2. Main parameters of evaluation and fairness

The evaluation method, main parameters, evaluation procedure and result and value adding status of aforesaid evaluation are as follows:

(1) Evaluation of equity values of Beijing Boyu and Chaoyang Jinmei

1) Thinking of evaluation

8-1-1-6

According to due diligence of this evaluation, the asset composition and business characteristics of the enterprise, all equities of its shareholders (net assets) are valued on the basis of audited financial statement of the evaluated entity, that is, the value of all equities of its shareholders results from evaluating the value of productive assets of the evaluated entity by using discounted cash flow (DCF) in the way of income, plus value of other assets, and minus value of other liabilities; that is, the value of all equities of shareholders is obtained indirectly through evaluating overall value of the enterprise.

2) Evaluation model

The basic calculation model of this evaluation is:

E = B-D

E: Value of all equities of shareholders of estimation object

B: Overall corporate value of estimation object

B=P+Ci +Q

Wherein: P: Value of productive assets of estimation object

ΣCi: Value of surplus assets and non-operating assets (liabilities)

Q: Value of long-term equity investment of estimation object

D: Value of interest-bearing debt of estimation object

3) Main parameters

The main parameters of income method evaluation include operating income, operating cost, period expense and discount rate; relevant operating income and discount rate are as follows:

Parameter

Beijing Boyu

Chaoyang Jinmei

Forecast period

Sustainable operation, the forecast period is perpetual, 5-year income growth period and the perpetual growth rate is 0% after 5 years.

From 2021 to 2025, the operating incomes are RMB109.46 million, RMB118.22 million, RMB125.31 million, RMB131.58 million and RMB136.84 million respectively.

From 2021 to 2025, the operating incomes are RMB62.19 million, RMB88.42 million, RMB123.21 million, RMB135.19 million and RMB144.37 million respectively.

12.70%

13.00%

8-1-1-7

Discount rate

Discount rate is confirmed by using Weighted Average Cost of Capital (WACC) model; of which, risk-free rate is determined by reference to average interest rate of medium and long term national debts issued in recent five years

(2) Evaluation of equity values of Chaoyang Tongmei, Baoding Tongmei and Nanjing Jinmei

1) Thinking of evaluation

The value of evaluation object is confirmed through reasonable evaluation of values of assets and liabilities of the enterprise on the basis of balance sheet of the evaluated enterprise at the evaluation benchmark date.

2) Main parameters

The evaluation method is asset basis method, and relevant assets are confirmed mainly through book value and replacement cost method.

3. Conclusion of evaluation

Asset basis method

As a whole, the pricing basis for the purchase of Beijing Boyu, Chaoyang Jinmei, Chaoyang Tongmei, Baoding Tongmei and Nanjing Jinmei by the Issuer is the evaluated equities of all shareholders; of which, the evaluation method adopted by final conclusion for Beijing Boyu and Chaoyang Jinmei is income method.

8-1-1-8

With respect to Chaoyang Tongmei, Baoding Tongmei and Nanjing Jinmei, asset basis method is adopted for confirming evaluated value mainly because: (1) Chaoyang Tongmei and Baoding Tongmei just start operation and suffer losses at the evaluation benchmark day, with large uncertainty on future proceeds and risks, and the income method cannot reflect the value of all their equities; in addition, Chaoyang Tongmei and Baoding Tongmei have large capital expenditures, with large amount and high degree of newness of noncurrent assets such as plants and machine, so it is reasonable to adopt asset basis method for evaluation; (2) After transferring its production business to Chaoyang Jinmei, Nanjing Jinmei only assumes the function of sale, and all its revenues depend on the production of Chaoyang Jinmei, lacking independent capacity of gaining profits; in the other hand, Nanjing Jinmei is reducing its single sale, and the income method cannot fairly reflect the value of all its equities, so asset basis method is adopted for evaluation. As a whole, it is reasonable for final evaluation conclusion of aforesaid three companies to adopt asset basis method as the evaluating method, and the transaction price paid by the Issuer for purchasing restructured object is fair.

4. The reason and reasonableness of large difference between the valuation at this asset restructuring of the Company and the valuation at the capital increase from third parties in January 2021

The reasons for large difference between the value estimated at this asset restructuring of the Company and the value estimated in January 2021 when the third party increases capital include:

(1) Different transaction backgrounds

Before this asset restructuring, there was either business overlapping or upstream and downstream relationship between the Company and the restructured parties without horizontal competition, involving lots of related party transactions. The purpose of this restructuring is to integrate business resources, deal with horizontal competitions and reduce related party transactions. Given all restructured parties are controlled by AXT, such restructuring denotes a combination involving enterprises under common control and an internal integration at the level of the Group.

8-1-1-9

The third party capital increase in January 2021 was a market-based investment by external entities, which were introduced by the Issuer for attracting capitals for business development. This capital increase and pricing was established through negotiation between the market-based entities and the Company after full consideration of prospect of the Company's listing by each investor.

(2) Different pricing bases

This asset restructuring is the combination of enterprises under same control, and the capital increase price of the Issuer is confirmed by the parties through negotiation on the basis of net assets per share.

The corporate value is confirmed through negotiation between the Issuer and external investors who invest in the Company based on their optimism on the future development after the restructuring taking into account the prospect of listing and market value of the Company.

(3) Difference in valuation scope and synergy after restructuring

Before restructuring, the Issuer is a single entity mainly dealing in indium phosphide, gallium arsenide and Germanium substrate, without a sound industrial chain.

Through restructuring, the Company integrates supply of raw materials of semiconductor substrates upstream such as PBN crucible, indium phosphide polycrystalline and high-purity gallium, with its main businesses covering the R&D, production and sales of semiconductor substrate materials, PBN materials and other high-purity materials, forming a complete industry chain of semiconductor substrate materials.

After completion of business handover between AXT and AXT-Tongmei in March 2021, original overseas business of AXT is transferred to the Issuer and its subsidiaries, and the Issuer deals with overseas customers directly, and the Company can conduct independent sales in the overseas market, with apparent industrial and resource synergy after the restructuring, which greatly improves the overall profitability and anti-risk ability of the Company, as well as the valuation thereof at the time of additional capital contribution by external investors after the restructuring.

(4) Effect of Valuation Adjustment Mechanism (VAM) on valuation

8-1-1-10

According to the provisions of Supplemental Agreement to Capital Increase Agreement of Beijing Tongmei Xtal Technology Co., Ltd. executed by the Company, AXT and external investors, investors will be entitled to require AXT to repurchase all or parties equities of the Company held by investors if the Company fails to realize IPO prior to December 31, 2022 (if the Company's IPO is under review at the expiry of such period, the repurchase shall be postponed to the time when IPO fails or the Company withdraws its application) or is under other special circumstances. In addition to such article of repurchasing equities, the Supplemental Agreement also contains special rights articles such as equity transfer limitation, preemptive right, priority in sale and anti-dilution. When buying shares, the external investors are protected by the VAM article, the consideration of which during negotiation among the parties properly increased the overall valuation of the Company.

As a whole, the large difference between the value estimated at this asset restructuring of the Company and the value estimated in January 2021 when the third party increases capital is reasonable.

(II) The time when equities of 5 subsidiaries such as Beijing Boyu were transferred and included in consolidated statement, and the time when this asset restructuring is completed

According to its industrial and commercial registration materials, the restructured parties (acquired entities) involve the following dates during procedure of this asset restructuring:

The indium phosphide polycrystalline produced by Chaoyang Jinmei is provided to the Company for single-crystal growth, high-purity gallium is provided to Chaoyang Tongmei for producing gallium arsenide single crystal ingot, and other high-purity metals and compounds are used for sale directly or through Nanjing Jinmei. PBN crucible produced by Beijing Boyu is indispensable consumption material for single-crystal growth of the Company, and is also sold together with other PBN materials to others. Baoding Tongmei produces and sells GaAs substrates based on the gallium arsenide single crystal ingot supplied by Chaoyang Tongmei through subsequent procedure of cutting, grounding and polishing. The Company is responsible for the production, R&D and sales of InP substrates and germanium substrates.

To sum up, after restructuring, the business positioning and work division of the Company and its subsidiaries are clear, forming a sound industrial chain of compound semiconductor substrate materials as a whole, with strong market competitiveness.

(V) The integration measures adopted by the Company in assets, business and personnel, and their effect, the measures and effect of controlling each subsidiary, and whether there is any risk of influencing stability of main operating business of the Company and effective control over subsidiaries.

1. The integration measures adopted by the Company in assets, business and personnel, and their effect

After acquiring the 5 companies such as Beijing Boyu, the assets, business and personnel of relevant entities do not change greatly, and its original business continues to operate and develop as follows:

In terms of assets, after restructuring, the 5 companies such as Beijing Boyu keep their major assets, and the main operating business continues to run as usual based on relevant assets.

In terms of business, after restructuring, the Issuer and its subsidiaries have clear responsibilities and continue to perform their respective functions based on original cooperation and work division. The Company operates well in the R&D, production

8-1-1-17

and sale of indium phosphide substrate, gallium arsenide substrate, germanium substrate, PBN material and other high-purity materials, so the integration effect is satisfying.

In terms of personnel, after restructuring, the Issuer completes equity reform, and engages WANG Yuxin and GUO Tao to act as deputy general managers, HAO Ze acts as financial manager, and SONG Jing acts as secretary of the board of directors; the 5 companies such as Beijing Boyu reserve their R&D and management teams, the personnel in relevant teams do not change greatly, and main personnel continue to perform original labor contracts and labor relationship.

Since aforesaid entities are under control of AXT prior to restructuring, have clear work divisions and cooperate with each other, this acquisition has no material influence on the assets, business and personnel of relevant entities and does not affect effective operation of each entity.

At the time of capital increase by external investors in January 2021, the Supplement to Capital Increase Agreement between AXT and external investors provided for the issues such as assets restructuring, establishment of overseas subsidiary, reduction of horizontal competition and connected transactions, with main contents and completion status as follows:

As of February 28, 2022, the inventory sold by the Company through AXT had a small balance, without realization of further sales, of RMB120,100, which was due to the fact that after products were sold to AXT in 2020, the demand parameters of downstream customers for products were changed, and AXT had not yet sold externally.

(II) The specific time and reason for the Company's sales to AXT from January to June 2021, the collection of accounts receivable from AXT at the end of the reporting period, and the transactions with AXT after the reporting period;

In March 2021, the Company successfully integrated its overseas sales business, selling products to overseas customers through AXT-Tongmei, whereupon AXT no longer engaged in the sales business after fully performing its orders on hand. Accordingly, the Company's sales to AXT during the period from January to June 2021 can be divided into two stages which are normal sales stage and inventory order destocking stage, as detailed below:

The Company has not sold any product to AXT since July 1, 2021. As of December 31, 2021, the balance of the Company's accounts receivable to AXT was 0.

(III) The specific process and implementation method of business and customer handover, showing the status of certification by the end customers of the Company's products sold through AXT and the basis for completing the handover in tabular form; the impact on the Company's production and operation of some customers who have not certified the products or have not been handed over up to now and the solutions; is there any case or risk of failure of certification and loss

8-1-1-25

of customers due to customer handover and change of sales model;

1. Specific process and implementation method of business and customer handover

The specific procedure and realization method of the Company's business and customer handover are as follows:

(1) Since March 2021, salesmen of AXT sent letters signed by CEO to customers, and the main contents of the letters are: AXT changes its sales entity into AXT-Tongmei, and notifies customers of the tax number and fund collection account of AXT-Tongmei; the production line, supply method and contractual terms related to production and sale are not changed.

(2) After receiving letters, customers implemented their internal procedure; since this business handover only involves the change of sales entity of the Company, and other cooperation methods do not change, not affecting product quality, performance or delivery, and customers are not required to conduct product certification again. After quickly completing changes to registered suppliers and payees, some customers will reply the Company by mail, and most customers will reply by telephone, and directly sign contracts/orders with AXT-Tongmei when issuing new orders in future.

(3) Former salesmen of AXT rescinded employment contracts with AXT, and concluded employment contracts with AXT-Tongmei; at the same time, AXT leased its offices to AXT-Tongmei; after completing internal procedure of AXT, relevant sales data and customer information were transferred to AXT-Tongmei. Therefore, the sales persons and sales teams dealing with overseas customers did not change and subsequent services and relationship with customers will not be affected.

After business and customer handover, AXT would not receive any new orders after completing orders which had been received by it. Since July 2021, the Company no longer sold products to AXT. The overall handover effect of the Company is satisfied. In 2021, the semi-conductor substrate materials of the Company realized the incomes of RMB626,751,800, an increase of 41.33% over previous year; main customers purchased more products, without any interruption of cooperation with customers due to handover of business and sales entity of the Company.

2. Status of certification by the end customers of the Company's products sold through AXT and the basis for completing the handover

According to the industry practice of semiconductor substrates, the downstream customers mainly implement product certification according to the production line of the supplier. Product certification is required for comparable companies in the same industry, such as National Silicon Industry (688126.SH) and SICC (688234.SH), to be recognized by customers.

During the procedure of certification, the Company and customers communicate mainly in respect of product parameters, including but not limited to dislocation density,

8-1-1-26

resistivity uniformity, thickness fluctuation value, warpage and surface particle size, and confirm relevant test equipment and test standard. After its product performance indexes comply with requirements of customers, the Company will supply small number of products to customers, and customers will validate to its downstream customers whether or not the epitaxy and chip grown on the basis of substrate can meet performance requirements of final products; after satisfying performance requirements of final products, the Company's customers complete internal certification; if customers do not change product performance, process and production procedure, such product certification is valid for a long term. During certification, both parties will continue to exchange technologies; after passing certification, customers will place orders, and will regularly (one year or several years) or irregularly visit production lines of the Company to confirm that no material changes happen on the standards of production line such as equipment and process. If material changes happen on equipment, production site and process of the Company, product certification is required again.

Since this handover only results in the change of selling entity (namely the entity signing the contract and receiving the payment) without changing the production line, relevant customers have no need to conduct product certifications again.

At present, AXT has completed customer handover with AXT-Tongmei, and the completion of handover of end customers which account for more than 90% of sales amount sold by the Company to AXT in 2021 is as follows:

In addition to aforesaid end customers, other key customers have completed handover. Refer to "I. (III). 1. The specific process and implementation method of business and customer handover" of this Question. Except for change of selling entity, this handover does not change the production line, supply method and contractual terms of the Company, and customers have no need to carry out product certification again. The overall handover effect of the Company is satisfied. In 2021, the semi-conductor

8-1-1-28

substrate materials of the Company realized the incomes of RMB626,751,800, an increase of 41.33% over previous year; main customers purchased more products, without any interruption of cooperation with customers due to handover of business and sales entity of the Company. In future, the Company will carry out marketing and maintenance at overseas markets through AXT-Tongmei, and ATX will no longer assume specific function of operation.

To sum up, the sales business restructuring only involves the internal business and structural adjustment of AXT Group, and does not change any production line. The original AXT customers do not need to re-certify the Company's products. All customers concerned have been successfully handed over to AXT-Tongmei. The Company does not encounter any loss of customers due to customer handover and change of sales model. After handover, AXT-Tongmei maintains good cooperation relationship with overseas customers; the purchase amount and orders of the customers increased. The Issuer has smoothly undertaken relevant overseas customers of AXT.

(IV) The Company's current customer acquisition modes, the reasons for the small number of sales staff, the acquisition of new customers and realization of sales revenue after restructuring, and the role of AXT in the Issuer's process of obtaining customers and orders;

1. The Company's current customer acquisition modes and the reasons for the small number of sales staff

(1) Current method of winning customers by the Company

Based on direct marketing, the Company obtains orders mainly through negotiating with potential customers and entrusting agents to promote. In terms of marketing, salespersons of the Company maintain long-term communication with downstream epitaxy manufacturers, OEMs, chip and apparatus manufacturers mainly through relying on historical customer resources, participation in exhibitions and industry conferences, orders actively placed by customers, and visiting potential customers, so as to know the demand dynamics of downstream customers, market supply & demand and work related to preparing sales plan. This is in line with industry practice. In terms of customer maintenance, since quality of products is stable, the demand for after-sale services of company products is small, and the salespersons of the Company are mainly responsible for communicating requirements of current customers and product performance.

Main customers of the Company are famous manufacturers in the world; during reporting period, the amount of products purchased by main customers from the Company increases constantly, and orders are sufficient to maintain full production capacity of the Company; currently, the Company sells its products overseas mainly via

8-1-1-29

AXT-Tongmei, and sells in China mainly through Beijing Tongmei; the main duties of salespersons are serving current customers, supplemented by exploring new customers. The revenues of the Company contributed by main customers increase year by year.

(2) Reasons for small number of sales staff

The number of sales staff of the Company is relatively small mainly because:

1) The industry to which the Company belongs has no high demand for number of salespersons. The customers in the compound semiconductor substrates industry are mostly downstream epitaxy manufacturers, OEMs, and chip and device manufacturers, and downstream industries are relatively concentrated, so customers are also relatively concentrated.

2) The Company has been dealing in III-V compound semiconductors for many years, with high reputation and popularity in the market and among main epitaxy manufacturers, OEMs, and chip and device manufacturers in China and other countries, so many customers express their intentions of cooperating with the Company through email and telephone.

3) The Company has established good cooperation with main downstream customers. The products of the Company have high technical barrier and threshold, and the Company owns core patented technologies of producing III-V compound semiconductor substrate materials. The Company's customers are mainly global well-known enterprises with years of cooperation with the Company. Under strict requirements for their suppliers, with each supplier including the Company into its list of qualified suppliers generally having been subject to its certification, the customers will not easily change their suppliers.

Therefore, small number of sales staff of the Company will not have adverse effect on business development and sustainable operation.

In future, the Company will continue to maintain good relationship with customers through in-depth analysis of customers' demands and technical R&D; it is expected that customers will continue to purchase from the Company; the sales staff of the Company meet the requirements of business development, and it is expected that the Company will not greatly increase its number of sales staff.

(3) Comparison with comparable companies

The semiconductor substrate field requires sales staff to meet high professional background and experience requirements. The sales staff needs to be familiar with the

8-1-1-30

indicators of the Company's products such as key performances and parameters, understands the in-depth needs of downstream customers, and makes timely communications in response to production issues on the part of downstream customers. In view of the professional characteristics of the semiconductor substrate industry in which the Company is located and the Company's industry position, the Company has fewer sales staff, but the sales team has rich industry experience and the ability to independently develop and serve customers and connect with the end customers - downstream manufacturers. A comparison of the proportion of sales staff between the Company and comparable peers in the same industry at the end of each reporting period is as follows:

Company Name

End of 2021

End of 2020

End of 2019

NSIG

Undisclosed

4.11%

4.73%

SICC

1.81%

1.33%

Undisclosed

Beijing Tongmei

1.50%

1.33%

1.04%

Note: The data of comparable companies are sourced from the annual reports and prospectuses of NSIG and SICC.

The above table indicates that the proportion of sales staff of the Company is relatively low compared to that of comparable peers, which is basically in line with that of SICC. The Company possesses more than 20 years of business and sales history, enjoys high reputation and customer recognition in the industry, and has established good cooperative relations with major downstream customers, requiring less sales staff.

2. Acquisition of new customers and realization of sales revenue after restructuring

The Company mainly develops new customers by participating in exhibitions and industry conferences, recommendation by customers, visiting potential customers, and other ways. Some customers also will actively place purchase orders with the Company owing to its prominent position in the industry. After the restructuring, the Company has won 23 new customers, including customers involving large amounts as follows:

3. Role of AXT in the Issuer's process of obtaining customers and orders

Before March 2021, the Company's semiconductor substrates were sold overseas mainly through AXT. In March 2021, the Company successfully integrated the overseas sales business, and AXT-Tongmei took over the existing customers of AXT. Based on the business adjustment within the group, AXT stopped selling the Company's products after executing the sales contract signed before March 2021. After March 2021, AXT's sales staff has become the employees of the Company. At present, the Company has an independent and complete sales team, carrying out business independently.

For one thing, the above-mentioned customers have cooperated with the Company for many years in view of its good product quality and service. For another, the business and customer handover only involves the change of seller entity within the AXT Group and will not affect the final product delivery. So the handover was completed quickly and the sales revenue from major customers grew rapidly after handover.

To sum up, based on the historical development of AXT and the unified arrangement within the group, AXT assumed the overseas sales function of semiconductor substrates before integration. After integration is completed, this function is performed by AXT-Tongmei and AXT no longer plays any role in the Issuer's sales system. The Issuer can independently win customers and orders.

(V) Transactions between AXT and other customers of the Company, and

8-1-1-32

reasons and rationality of transaction.

In December 2020, the Company completed the acquisition of Beijing Boyu and other entities. Before March 2021, AXT serves as the entity of overseas sales according to the decision at the group level to sell semiconductor substrates to overseas customers, and there was no overlap with other semiconductor material customers of the Issuer.

Nevertheless, AXT has transactions with some overseas customers of Beijing Boyu, a subsidiary of the Company, mainly because these overseas customers purchased PBN crucibles and PBN plates from Beijing Boyu while purchasing semiconductor substrates from AXT, as detailed below:

In general, the proportion of main raw materials required for the Company's production and operation from related party is relatively low. In 2019 and 2020, the reason why the proportion of high-purity arsenic purchased by the Company from related party was high was that the suppliers of high-purity arsenic were Dongfang Hi-purity and YONEDA CORPORATION, where the purchase from YONEDA CORPORATION was completed through AXT. As the production qualification of Dongfang Hi-purity has expired and the new certificate is being handled, the Company has stopped purchasing products from Dongfang Hi-purity since June 2021, and purchased raw materials overseas through AXT-Tongmei since March 2021. So the proportion of high-purity arsenic purchased from related party dropped significantly in 2021.

(II) The final purchasing source of raw materials supplied by AXT, the goods flow and capital flow of raw materials purchased by the Company, the process and effect of the above-mentioned suppliers switching to supply directly to the Company after the purchasing entity is adjusted, and whether there are any cases or risks that the Company cannot continuously and stably purchase raw materials from the original suppliers of AXT (if any, state the impact on the Company's operation);

1. The final purchasing source of raw materials supplied by AXT, and the goods flow and capital flow of raw materials purchased by the Company

During the reporting period, the final purchasing source of raw materials supplied by AXT is as follows:

Note: Information of suppliers are sourced from public network through retrieval.

The goods flow and capital flow of raw materials purchased by the Company are detailed as follows:

(1) Goods flow

After AXT places a purchase order to overseas suppliers, overseas suppliers provide raw materials as required by the order. If purchasing occurs in the United States, AXT will centrally purchase raw materials in the United States and then deliver them to the Company. If purchasing occurs in other countries or regions outside China and the United States, AXT will require the raw material supplier to deliver the goods directly to the Company.

After the raw materials arrive at the customs, the Company entrusts the customs declaration agency to handle the customs declaration and import formalities. After customs declaration, the raw materials are transported to the Company's warehouse and accepted, and then put into storage after successful acceptance. The Company makes the receiving list and sends it to AXT for verification.

(2) Capital flow

The Company settled with AXT according to the raw material requisition records and made payment by foreign exchange telegraphic transfer.

2. Process and effect of the above-mentioned suppliers switching to supply directly to the Company after the purchasing entity is adjusted, whether there are any cases or risks that the Company cannot continuously and stably purchase raw materials from the original suppliers of AXT (if any, state the impact on the Company's operation)

8-1-1-43

In March 2021, AXT-Tongmei and AXT completed the business handover. The overseas sales and procurement functions of AXT were transferred to AXT-Tongmei, and all related staff joined AXT-Tongmei. In view of the fact that the above-mentioned overseas suppliers have cooperated with AXT for a long time and the related staff of AXT has joined AXT-Tongmei, AXT-Tongmei can successfully re-sign purchase contracts or orders with those suppliers and release purchase requests. The purchase, customs declaration, and logistics transportation modes are the same as that adopted by AXT. The adjustment of purchasing entity has not increased the supply cost and difficulty of suppliers, so there is no loss of supplier.

According to the purchase contracts or orders signed by AXT-Tongmei and the supply of goods by overseas suppliers to AXT-Tongmei, the Company's overseas purchase amount in 2021 was RMB65,699,500, representing an increase compared with that in 2020. Additionally, major overseas suppliers have remained relatively stable.

The raw materials purchased by the Company from the original suppliers of AXT mainly include high-purity arsenic, Germanium ingots, cutting, grinding and polishing materials, cleaning consumables, and packaging materials, all of which can be stably supplied involving no monopoly. In addition, with the rapid development of compound semiconductor industry in China, the number of Chinese suppliers has greatly increased, and the quality of raw materials provided by them has basically met the Company's requirements. For example, the Company increased the quantity of Germanium ingots purchased from companies including Hengyang Hengrong High Purity Semiconductor Material Co., Ltd. and Jiangsu Ningda Environmental Protection Co., Ltd., to ensure the production of Germanium substrates; Jiamei Hi-purity has resumed production and supplied high-purity arsenic to the Company; in addition, the Company is purchasing increasingly more cutting, grinding and polishing materials, cleaning consumables, and packaging materials from Chinese suppliers.

In summary, the Company has established a relatively mature global procurement system, which can ensure sustainable and stable overseas procurement. Meantime, the Company has reached more cooperation with Chinese suppliers, and further ensured stable raw material procurement, avoiding out-of-supply and shortage.

Moreover, the Company has given sufficient risk warnings on the dependence of some key raw material suppliers in "II. (II) Risk of reliance on the suppliers of certain critical raw materials and fluctuations in the raw material prices" in Section IV "Risk

8-1-1-44

Factors" of the Prospectus.

(III) Purchasing source and mode of the Company's production equipment, and the reason and rationality of purchasing production equipment through AXT during the reporting period;

1. Purchasing source and mode of the Company's production equipment

With a global procurement system, the Company formulated standardized procurement regulations, implemented standardized procurement control procedures, and established long-term mutually beneficial and win-win cooperation with suppliers, thus ensuring stable and timely supply.

The Issuer formulates the equipment procurement plan according to business requirements and annual plans, and selects suppliers through inquiry, bidding and tendering, competitive negotiation, and other ways. The Company mainly develops the annual equipment purchase plan based on whether the capacity of the project corresponding to the current equipment, the need for process optimization, and the capacity reserve for future development can meet the increasing order requirements. Equipment shall be uniformly purchased by the Engineering Technology Department, and the procurement project shall be established after internal approval by the Company. According to the project approval form and the final quotation of the supplier, the engineering technician generates an inquiry sheet and submits it to the Company for internal approval. After fulfilling the approval process, the engineering technician will create a purchase order or project contract that contains the supplier information and confirmed price, and distribute it to the corresponding suppliers.

The Company's production equipment is mainly purchased from Chinese equipment manufacturers and other suppliers outside China. Among the equipment to be purchased from abroad, those for routine production that are easily worn-out and need to be delivered by manufacturers in batches such as single crystal polishing machine, single crystal furnace, and vacuum furnace controller are usually purchased by the Company centrally through AXT who will deliver them to the former, and those to be delivered in a single batch are ordered directly by the Company from equipment manufacturers outside China for direct delivery to the Company.

2. Reason and rationality of purchasing production equipment through AXT during the reporting period

During the reporting period, the Company purchased professional equipment for

8-1-1-45

the production of compound semiconductor substrates from AXT, amounting to RMB11,596,900, RMB6,025,400, and RMB5,760,500 respectively. The details are as follows:

The Company's procurement of production equipment through AXT is determined

8-1-1-46

by AXT's organizational structure and its long-term business development model. At the early development stage of the Company, the III-V compound semiconductor material industry has just started to develop in Chinese Mainland, and there were only a few qualified suppliers, especially the suppliers of key equipment. In this context, to facilitate procurement and ensure stable production, the Company centrally purchased the easily worn-out equipment for routine production such as single crystal polishing machine, single crystal furnace, and vacuum furnace controller through AXT. Considering the convenience of procurement, the Company continues to import such kind of equipment through AXT. In 2021, after AXT fulfilled the original equipment purchase orders, the Company purchased equipment directly or through AXT-Tongmei instead of AXT.

The price of equipment purchased by the Company from AXT is based on that purchased by AXT from equipment suppliers, so there is no obvious unfairness in price in related transactions. It is reasonable for the Company to purchase production equipment through AXT.

As the number of III-V compound semiconductor material equipment suppliers has greatly increased in Chinese Mainland, and the quality of equipment provided by them has basically met the Company's requirements, the Company has imported increasingly less equipment from suppliers outside China. Equipment with high consumption frequency such as single crystal furnace will be produced by Beijing Boyu in the future. Other equipment that is purchased less frequently will be purchased directly by the Issuer or AXT-Tongmei and will not be purchased through AXT in the future.

2.3

According to the submissions, 1) In November 2021, the Issuer signed a technology license agreement and a trademark license agreement with AXT, in which AXT granted its own intellectual property rights, authorized patents and pending patents to the Issuer and its controlled subsidiaries, and granted a trademark license to the Issuer and its subsidiaries; 2) The Issuer owns 42 domestic invention patents, four (4) of which are jointly owned by the Issuer and AXT.

AXT

The Company is in the semiconductor material industry, and its business development does not depend significantly on trademarks. The trademarks mentioned above are not necessary ones for the Company's production and operation. As a controlled subsidiary of AXT, the Company mainly uses relevant trademark patterns in daily management of enterprise, internal identification in plant and product packaging.

In order to ensure the continuity of the Company's business management and trademark use, the Company signed a Trademark License Agreement with AXT on

8-1-1-53

November 4, 2021, which stipulates that: AXT will license the above trademarks to the Company and its subsidiaries for free as an integral part of the Company's corporate name for the manufacture, marketing and sale of products; The license term begins on March 1, 2021 and is valid forever.

In summary, AXT has licensed the relevant registered trademarks owned by itself to the Company for free.

(II) AXT has already no actual business, the reason for taking the licensing mode rather than transfer and the fairness of license royalties;

1. Reasons for adopting licensing mode rather than transfer

In terms of technology licensing, due to the cross-licensing agreement between AXT and M, AXT has restrictions on transferring patents, and AXT patents cover Europe, the United States, Japan, South Korea, Taiwan, China and other countries and regions. Since 2021, various countries and regions have introduced laws to increase support for the semiconductor industry. In this context, there are many restrictions and policy uncertainties in the cross-border transfer of semiconductor-relevant patents. In view of the above reasons, although AXT has no actual business, the Issuer and AXT still take the licensing mode rather than transfer to receive the AXT- related right to use the patent.

On trademark licensing, as AXT itself is still a NASDAQ listed company, foreign public relations publicity and information disclosure are still required to use relevant trademarks. To facilitate the integration of the Issuer's sales operations while ensuring AXT's daily publicity and disclosure needs, AXT licenses the trademark to the Issuer at no cost, and the license term begins on March 1, 2021 and is valid forever.

2. The fairness of license royalties

Technology license royalties granted by AXT to the Issuer include intellectual property rights, licensed patents and pending patents owned by AXT. The above license royalties are determined according to the Intangible Assets Appraisal Report issued by Armanino LLP, an overseas appraisal agency, and through negotiation by both parties. The appraisal value is USD1.228 million, the appraisal method is income approach, and the appraisal base date is January 1, 2021.

8-1-1-54

According to the appraisal report issued by Armanino LLP, the fair value of the right to use patented technology was appraised using the income method. The main parameters for appraising the fair value of such use right are as follows:

Main parameters

Descriptions

Appraisal purpose

Fair value of the authorized patent rights and intellectual property rights

Appraisal base date

Appraisal method

Income method

Contribution rate of patent technology use right

The technical sharing rate is 15% in 2021, and it is reasonably expected that the proportion will decline at an annual attenuation rate of 1.5% in the next decade.

Discount rate

13%

Armanino LLP, upon prediction and calculation of the Company's sales revenue from relevant products from 2021 to 2030, and in light of the technical sharing rate of AXT patented technology during the license period, finds that the present value of technology license royalties for each year after discounting totals to USD1.228 million; In addition, the royalty rates of 12 US listed companies have been selected by Armanino LLP for comparative analysis. The royalties for AXT are reasonably priced.

In summary, the above technology license royalties are evaluated according to the Intangible Assets Appraisal Report issued by Armanino LLP, an overseas appraisal agency, and agreed by the Issuer and AXT through negotiation, the pricing of license royalties is fair.

AXT grants a license on the trademark which is still in its use to the Issuer on a permanent and royalty-free basis, rendering the trademark to be jointly used by both parties.

(III) For the joint patents, whether there are currently arrangements for licensing to a third party in the use and planning of AXT.

As of February 28, 2022, the Company has been granted a total of 53 invention patents inside and outside China, among which four (4) patents are jointly owned by the Company and AXT, its controlling shareholder. The Company was originally a

8-1-1-55

wholly-owned subsidiary of AXT, and declared the above four (4) patent applications as joint patents with AXT. The details of such jointly patents are as follows:

1. All patents and technologies necessary for the Company's production and operation have been transferred or authorized to the Company.

2. The Issuer belongs to the semiconductor material industry and does not have significant dependence on trademarks for business development; The relevant registered trademarks owned by AXT are not necessary trademarks for the Company's production and operation, but in order to ensure the continuity of the Company's business management and trademark use, AXT has licensed the relevant registered trademarks owned by itself free of charge to the Issuer for use.

2.4

According to the submissions, during the reporting period, AXT has dispatched R&D players to assist the Issuer in research and development, and these players have been converted into Company employees since March 2021.

The Issuer is required to explain: (1) whether the sources of the Company's core technology are legal and compliant, and whether they are disputable or have potential disputes; (2) during the reporting period, whether the Company and AXT hold cross-posts or part-time jobs in terms of management personnel and core technical team, or advance salary on behalf of the Company.

I. Explanations from the Issuer

8-1-1-59

(I) The sources of the Company's core technology are legal and compliant, whether they have disputes or potential disputes;

In 1998, AXT established its predecessor company Tongmei Co., Ltd in Beijing, and gradually transferred its production and research and development to Beijing Tongmei Co., Ltd., and invested related technology of compound semiconductor substrate into Tongmei Co., Ltd. On the basis of these technologies, the Company has continued to carry out technological development and innovation for more than 20 years, and upgraded and innovated polycrystalline synthesis, single crystal growth, material purification and other processes and various devices, in order to meet the downstream demand and technological development trend.

Prior to March 2021, AXT dispatched R&D players to assist the Issuer in research and development. These players are mainly engaged in overseas customer communication, overseas product research and development, testing and other R&D activities. Since March 2021, these R&D players have been converted to company employees. The main core research and development work of the Issuer is completed on its own, based on which, the Issuer has applied for a series of patents or formed technical secrets, generating its core technologies, patents and products, with its current core technologies coming from its independent research and development.

In summary, the core technologies of the Company are independently researched and developed. The source of core technologies is legal and compliant, and there are no disputes or potential disputes.

(II) During the reporting period, whether the Company and AXT hold cross-posts or take part-time jobs in terms of management personnel and core technical team, or advance salary on behalf of the Company;

During the reporting period, the Company and AXT do not hold cross-posts or take part-time jobs in terms of management personnel or core technical teams.

During the reporting period, AXT disbursed salaries in the amount of RMB2.4354 million, RMB3.835 million and RMB736,100, respectively, to Mr. VINCENT WENSEN LIU, the general manager of the Company. As stated by AXT, the Company was not required to reimburse such amounts, and corresponding accounting treatments

8-1-1-60

have been made by the Company therefor. After March 2021, no circumstances as above have happened again. There is no other disbursement of salaries except the above.

In order to actively promote the Company's research and development efforts, AXT sent R&D players to assist the Company's research and development, and the Company paid subsidies of RMB1,070,500, RMB1,049,900 and RMB415,600, respectively to those R&D players during the reporting period. Given the Company, who was formerly a wholly-owned subsidiary of AXT, needed to maintain close communication with overseas advanced customers for overseas business, AXT dispatched some overseas players to assist the Company in R&D. All relevant R&D players take office in AXT, but not in the Company, without cross-employment or part-time job. The Company has paid the relevant subsidies according to the service time of the relevant personnel, which does not belong to salary payment on behalf of AXT. Starting from March 2021, the above-mentioned R&D players have been converted to employees of the Company.

The Company has an independent personnel management system, and all the directors, supervisors and senior managers of the Company are elected and appointed in strict accordance with the relevant provisions of the Company Law and the Articles of Association. The management personnel and core technical team of the Company take full-time job and receive remuneration in the Company, and they do not hold positions other than directors and supervisors in the controlling shareholders and other enterprises controlled by the Company, nor do they hold positions in other enterprises with the same or similar business of the Company.

2.5

The Sponsor and the Issuer's Attorney shall specify whether the Issuer business is complete, whether the relevant sales, procurement, assets, personnel and technology are confused with the controlling shareholders and the companies they control and share in and whether the Issuer has verification procedures, evidences and conclusions performed for the independent ability to continue

8-1-1-61

operations directly to the market, and give a clear opinion on whether the Issuer meets the requirements of the relevant rules for business integrity and independence.

Reply:

I. Basic information of the Issuer

As regards sales and procurement, before March 2021, based on the unified arrangement within the Group, the Issuer sold semiconductor substrate material products and also purchased some main raw materials overseas through AXT, its controlling shareholder. After March 2021, the business handover between AXT and AXT-Tongmei, a subsidiary of the Issuer, was completed whereupon AXT-Tongmei was independently responsible for overseas procurement and sales, and AXT no longer engaged in specific business after accomplishing the ongoing orders.

As regards assets and technology, in addition to independent plants, equipment and sound production processes, the Issuer has formed patented and non-patented technologies during production and R&D. In November 2021, the Company entered into a Technology License Agreement and a Trademark License Agreement with AXT, whereby it is agreed that AXT shall grant the Company and its controlled subsidiaries licenses to use AXT's intellectual property rights, patents (whether issued or pending) and trademarks on a perpetual basis. In 2021, AXT-Tongmei, a subsidiary of the Company, rented real estate from AXT as office space against paying the rent of RMB1.5068 million, recognizing right-to-use assets of RMB5.1358 million therefor. The above real estate is only used by AXT-Tongmei for daily office work, without a material impact on the Company's business and asset independence.

As regards labor force, since March 2021, AXT has handed over its business to AXT-Tongmei, with its relevant sales, procurement and R&D teams having re-signed labor contracts with the latter, while only retaining some necessary personnel to be responsible for information disclosures, investor relations, finances and other related matters in the US capital market. As of December 31, 2021, the Company has a total of 1,396 employees, who independently undertake such functions as procurement, sales, R&D and management.

To sum up, the Issuer maintains its business integrity, having no confusion with its controlling shareholder and the companies controlled or invested by the latter in

8-1-1-62

respects of relevant sales, procurement, assets, personnel and technology. The Issuer has the ability to directly conduct market-oriented operations as an independent going concern.

AXT's board meeting can be divided into regular meeting and ad hoc meeting. The regular meeting shall be held at the place, date and time determined by the board of directors and announced to all directors.

(3) Functions and powers of different types of directors

Directors of AXT are, according to their term of office, composed of three classes i.e. Class I Director, Class II Director and Class III Director. The term of office for each class of directors will expire at the annual general meeting of shareholders in the third year after their election.

Except for difference in the term of office, the above different classes of directors

8-1-1-69

enjoy the same functions and powers, and each director has one vote on decision-making matters related to operation. It is a common practice of listed companies in the US to classify directors by term of office.

2. Whether MORRIS SHEN-SHIH YOUNG plays a special role in AXT's operation, has a special decision-making position on major matters, and can actually control the board of directors and AXT in combination with his role in AXT's operation

(2) As the board chairman of AXT, he presides over the board meetings, and participates in decision-making matters related to AXT operation together with other directors. Since directors of various classes of AXT differ in term of office only, directors do not have different functions and powers due to different classes, so MORRIS SHEN-SHIH YOUNG has the same decision-making status with other directors, enjoys one vote on decision-making matters related to operation, and the final decision-making matters shall be voted by a majority of directors attending the meeting and reaching a quorum.

As a whole, as CEO of AXT, MORRIS SHEN-SHIH YOUNG is responsible for managing daily operation issues of AXT, and only has one vote in the board of directors as a director of AXT; he does not have a special decision-making status on major matters, cannot actually control the board of directors and AXT, and does not play a special role in AXT's operation.

I. Explanations from the Issuer

(I) The background and reasons of AXT's share investment in Beijing Jiya, Jiamei Hi-purity and other enterprises, The relationship between the business of the above enterprises and the main business of the Company, and whether there is a potential conflict of interest between the business of the above enterprises and the main business of the Company

The Company focuses on the R&D, production and sales of indium phosphide, gallium arsenide and germanium substrate materials, PBN materials and high-purity materials, and mainly realizes revenue and profits by selling related products to downstream epitaxy manufacturers, foundry manufacturers, chip and device manufacturers, scientific research institutes and other customers.

In order to ensure the stable supply of raw materials in the upstream substrate production, the Company and its controlling shareholder AXT actively seek expansion to the upstream business and deepen the cooperation with raw material suppliers by way of equity investment including AXT's investing in Beijing Jiya and Jiamei Hi-purity in 1999 and 2001 respectively.

Beijing Jiya mainly produces and sells gallium. Its headquarters is located in Beijing, and its production base is set up in the plant area of Shanxi Aluminum Factory in Hejin City, Shanxi Province. The production process is to efficiently extract gallium

8-1-1-85

from the Alumina Bayer Process Solution, with purity levels of 4N and 5N; its main customers are compound semiconductor material enterprises, photoelectric material manufacturers, magnetic material manufacturers and other material manufacturers. At present, the commercial extraction of gallium is mainly extracted from alumina mother solution. Therefore, the production bases of domestic gallium manufacturers cooperate closely with nearby aluminum factories, and the shareholders of gallium manufacturers will operate aluminum factory generally, such as Beijing Jiya, Xing'an Gallium, Tiandong Jinxin Gallium, Pinglu Youying Gallium and other enterprises. Therefore, gallium is essentially a by-product of aluminum factories, providing basic raw materials for material enterprises in specific industries. At present, the high-purity gallium produced by the Company is mainly purified and extracted from metal gallium, mainly having a purity level of 6N and 7N. Jiamei Hi-purity's main product is high-purity arsenic, which is one of the raw materials of the Company's main product gallium arsenide substrate.

In December 2020, in order to solve horizontal competition and integrate business resources, AXT and the Company carried out asset restructuring, with the Company acquiring 100% equity in Beijing Boyu, Baoding Tongmei, Chaoyang Tongmei, Nanjing Jinmei and Chaoyang Jinmei. Following such restructuring, raw material suppliers such as Beijing Boyu and Chaoyang Jinmei have been incorporated into the Company's system for PBN crucible, high-purity gallium and other raw materials that are hard to be supplied in China with high technical difficulty and high added value, who at present can not only be self-sufficient but also have remaining production capacity for external sales thereby bringing revenue and profits to the Company. For other important raw materials that can be stably supplied in China, the Company continues to improve its cooperation with Beijing Jiya, Jiamei Hi-purity and other suppliers by means of equity investment from AXT, so as to ensure the stable supply of raw materials.

In conclusion, Beijing Jiya and Jiamei Hi-purity and the Company are of an upstream-downstream relation. All parties operate independently and make independent decisions. There is no potential conflict of interest on the part of the

8-1-1-86

Company by AXT's equity investment in the above two companies.

(III) The main business and operating performance of Dongfang Hi-purity, the background and reasons for transferring the equity of Dongfang Hi-purity to AXT before filing, and whether Dongfang Hi-purity commits any violations.

1. Main business and operating performance of Dongfang Hi-purity, and background and reasons for transferring equity in Dongfang Hi-purity to AXT before filing

The main business of Dongfang Hi-purity is to produce and sell Hi-purity arsenic.

8-1-1-87

Its main product Hi-purity arsenic is one of the main raw materials for the production of gallium arsenide substrates.

The operating performance of Dongfang Hi-purity from the beginning of the reporting period to the transfer of its equity is as follows:

Note: the above data has not been audited.

As the high-purity arsenic produced and sold by Dongfang Hi-purity is one of the raw materials of the Company's main product gallium arsenide substrates, in order to ensure the stability of the Company's raw material supply, the Company made share investment in Dongfang Hi-purity in June 2011. In November 2021, the Company transferred its 45.97% equities of Dongfang Hi-purity to AXT's controlling subsidiary Chaoyang Limei. The background and reason of such equity transfer are as follows:

(1) Due to the expiration of the safety production license held by Dongfang Hi-purity, the new license is under processing and there is great uncertainty of obtaining the new license based on interview with Li Bo, the actual controller of Dongfang Hi-purity, since it involves long-term and complicated formalities of examination and approval. Since June 2021, the Company no longer purchased products from it, and decided to transfer its 45.97% equities to AXT.

(2) Currently, the Company mainly purchases high-purity arsenic from foreign suppliers such as AMALGAMET CANADA LP and YONEDA CORPORATION. The parties have cooperated for many years and there is no dispute or potential dispute over any supply. In addition, Jiamei Hi-purity resumed production and supplied to the Company, so the stability of supply of high-purity arsenic to the Company can be guaranteed.

8-1-1-88

(3) The Company established controlling subsidiary Chaoyang Xinmei in February 2021, which is mainly engaged in production and marketing of high-purity arsenic. Currently, Chaoyang Xinmei is applying for issuance of project construction and safe production permit; in future, it can supply high-purity arsenic to the Company regularly.

The Company employs a third-party institution to evaluate 45.97% of the shareholders' equity of Dongfang Hi-purity involved in the proposed equity transfer by using the asset-based method, and to issue an asset evaluation report, which indicates that the transfer price is fair. The Company signed the Equity Transfer Agreement with Chaoyang Limei, a subsidiary of AXT, on November 19, 2021. The Company transferred the equity of Dongfang Hi-purity to Chaoyang Limei through negotiation based on the appraisal price, and completed the industrial and commercial change registration procedures on November 24, 2021.

2. Whether Dongfang Hi-purity commits any violations

According to the supporting documents issued by Donghai County Market Regulation Administration, Donghai County Taxation Bureau of the State Taxation Administration, Lianyungang Donghai Ecology and Environment Bureau, Donghai County Emergency Management Bureau, Donghai County Human Resources and Social Security Bureau, Donghai County Industry and Information Bureau, Shuangdian Police Station of Donghai County Public Security Bureau, Shuangdian Town Natural Resources Office of Donghai County Natural Resources and Planning Bureau, and other government departments, as well as through public online search and interview with the general manager of Dongfang Hi-purity, it is confirmed that Dongfang Hi-purity is not subject to administrative punishment by such government departments due to violations of laws and regulations during the reporting period.

Single-element semiconductor materials, III-V compound semiconductor materials and wide-band gap semiconductor materials are known as the first generation, the second generation and the third generation semiconductor materials according to their chronological order of appearance. Different semiconductor materials have different characteristics and uses. At present, the downstream application fields of silicon, germanium, gallium arsenide, indium phosphide, silicon carbide and gallium nitride have low overlap with each other. As such, there is no intergenerational iterative relationship between different semiconductor materials.

Single-element semiconductor silicon is the most widely used semiconductor material at present. Due to the rich reserves of silicon elements, mature technology and industrial supporting facilities as well as relatively low cost, more than 90% of chips and devices, including the most common CPU, GPU and other logic and storage chips, are made of silicon materials. Under the influence of Moore's law, silicon-based chips keep developing towards more advanced processes, manifested in smaller process nodes, such as 14nm, 7nm and 3nm, as well as more complex structures, such as 128-layer and 192-layer 3D NAND. In the generic scenarios with the requirements that can be met by the performance of silicon-based chips, it is generally difficult for silicon materials to be replaced by other materials.

However, in special scenarios with the requirements that go beyond the performance of silicon-based semiconductors, such as high frequency, luminescence, high power, high voltage and other application scenarios, III-V compound semiconductor materials and wide-band gap semiconductor materials, among others,

8-1-1-94

are needed, the market demand of which increases with the growth of their existing downstream application markets and the emergence of new application scenarios, with the increase mainly from the incremental markets, rather than alternative markets for silicon and other semiconductor materials.

In recent years, wide-band gap semiconductor materials witness a high market and investment heat, mainly driven by the broad incremental markets of electric vehicle power devices and charging pile power devices with the rapid development of new energy vehicle industry. Wide-band gap semiconductor materials, although they appeared later than III-V compound semiconductor materials, have been used in industry for more than 30 years, which are not an upgrade and iteration of III-V compound semiconductor materials.

The growth of market demand for 5G, new generation displays, data centers, driverless vehicles, mobile phone face recognition and wearable devices, etc., has broadened the demand for III-V compound semiconductor materials, leading to a certain future market growth for such materials.

2. Introduction to the overlapping areas and scenarios of different types of semiconductor materials

It can be seen from the above that the main application scenarios of different semiconductor materials, while being wide and varying from each other, have some overlaps in certain fields, mainly in the fields of mobile communication RF and LED, as detailed below:

(1) Mobile communication RF

Different types of semiconductor materials can all be used in RF devices for mobile communication, but the frequency bands of the corresponding devices are different. Gallium arsenide RF devices can be used with working frequency of up to 8Ghz, and suitable for 4G and 5G mobile communication devices. SOI RF devices are mainly used within 3.5Ghz of working frequency, and suitable for 2G, 3G and 4G mobile communication devices and communication base stations. Gallium nitride RF devices, while being used within 40GHz of working frequency, have a high requirement for power density, and are thus mainly applied in communication base stations.

8-1-1-95

In view of the above, at present, different semiconductor materials have different applications in the field of mobile communication. Gallium arsenide and silicon on insulator (SOI) RF devices are mainly used in mobile devices, and gallium nitride RF devices are mainly used in communication base stations, both of which are complementary rather than competitive with each other as to their applications in the field of mobile communication.

(2) LED

The III-V compound semiconductor material gallium arsenide and the wide-band gap semiconductor material gallium nitride are both used in LEDs. Gallium arsenide mainly transmits red, yellow and infrared light while gallium nitride mainly sends out blue, green and ultraviolet light. The light colors of photoelectric devices made from both semiconductor materials are different, which can be used together in LED display scenes, showing complementation rather than competition or replacement relationship between them.

3. Competitive advantages and disadvantages as well as future development trend of III-V compound semiconductor material products

(1) The competitive advantages and disadvantages of III-V compound semiconductor material products

1) Competitive advantages

Different types of semiconductor materials mentioned above have their own characteristics and comparative advantages in specific application scenarios, without absolute substitutability. In addition to the above overlapping application scenarios, in potential new application scenarios in the future, compared with other semiconductor

8-1-1-96

materials, III-V compound semiconductor materials have such competitive advantages as are mainly embodied in the following aspects:

First, compared with silicon materials, as direct band gap materials, gallium arsenide and indium phosphide have higher luminance and electron mobility and can better adapt to the environment of high temperature, high voltage and high radiation, which can, therefore, be applied to the fields such as 5G RF devices, LED light-emitting devices, laser devices and optical communication laser devices where silicon materials cannot be applied;

Second, compared with silicon carbide and gallium nitride, gallium arsenide and indium phosphide have higher luminous efficiency, and thus are more suitable for commercial applications in the fields of high-end displays and low-power small devices. Additionally, gallium arsenide has a comparatively mature industry chain with a low production cost of downstream devices, which fits better for large-scale commercial applications;

2) Competitive disadvantages

In potential new application scenarios in the future, compared with other types of semiconductor materials, III-V compound semiconductor materials have such competitive disadvantages as are mainly reflected in the following aspects:

Compared with silicon materials, III-V compound semiconductor materials usually have a high price given the high technical difficulty in the production of GaAs

8-1-1-97

and InP substrates, and are in a supporting industrial chain pending mature, rendering it difficult for them to compete with silicon materials in the application scenarios if the requirements can be met by the performance of the latter;

Compared with wide-band gap semiconductor materials, III-V compound semiconductor materials have a poorer band gap necessitating their use at a higher power, making it less competitive on this regard.

(2) Future development trend of III-V compound semiconductor materials

1) Technology development trend and opportunities of III-V compound semiconductor materials

InP substrate and GaAs substrate are both moving toward larger sizes, lower defect densities, and higher surface quality. In years to come, 8-inch GaAs substrate and 6-inch InP substrate will have increasing supply and market demand so as to further enhance the efficiency of chip preparation, promote chip performance consistency, reduce the costs of chip preparation, and also bring new demand and increment to the markets of indium phosphide and GaAs substrate.

Currently, the semiconductor industry in the world is moving to mainland China. With the semiconductor industry moving to mainland China, mainland China, as the world's largest semiconductor end-use market, will attract more domestic and foreign semiconductor enterprises to establish factories, which will further promote the overall development level of the domestic compound semiconductor industry chain. The supporting environment of compound semiconductor industry chain in mainland China is expected to enhance significantly in the future, with continuous expansion in the market share.

2) Market space brought by development of downstream industry of III-V compound semiconductor materials

The main market of downstream applications of indium phosphide substrate includes 5G base station, data center, Lidar and wearable device.

With the rapid growth of 5G network and data center traffic, the market demand for higher-speed optical modules continues to increase. As scenarios such as data

8-1-1-98

centers and core backbone networks enter the era of 400GHz and higher rates, the rate of laser chips required for a single channel is increasing accordingly. The demand for indium phosphide substrates, an essential basic raw material for optical modules, will also continue to grow.

The application field of lidar is also expanding. In addition to the field of unmanned driving, including advanced assisted driving, it will bring a broader market for lidar. As an important raw material in lidar chips, indium phosphide substrates will also bring new opportunity for business growth.

After iWatch was invented, major manufacturers have followed suit. Wearable devices will continue to improve people's lifestyles such as sports, health, leisure and entertainment. The market now generally expects that the growth space of wearable devices will exceed that of mobile phones and tablets; wearable devices faces broad development prospect, and it will also bring significant demand for indium phosphide substrates.

The main markets for downstream applications of gallium arsenide substrates include radio frequency devices, LEDs, VCSEL facial recognition, and high-power semiconductor lasers.

Currently, GaAs RF devices are mainly used in mobile phones, which directly determine the wireless communication distance and signal quality of mobile terminals and base stations. With the popularization of 5G, 5G smartphones and various forms of 5G terminal products continue to develop and increase. The shipment of 5G mobile phones and other 5G terminal products continues to increase, and the growing demand for mobile phones and mobile terminals also provides an important market guarantee for gallium arsenide substrates.

GaAs substrate is the basic material of red LED light-emitting devices. LEDs can be divided into conventional LEDs, Mini LEDs, Micro LEDs and other types based on chip size. Conventional LEDs are mainly applied in general lighting, outdoor large displays, etc. Mini LEDs and Micro LED are applied to a new generation of display. Benefiting from technological innovation and science progress, the application scenarios of display technology are constantly enriched, and the market space is

8-1-1-99

constantly expanding. The industry will experience long-term rapid development, greatly driving the growth of GaAs substrate market.

Gallium arsenide substrate is the basic material of VCSEL laser. VCSEL is the basic sensor of 3D sensing technology. With the development of 5G communication technology and artificial intelligence technology, and benefiting from the wide application of IoT sensing technology, it has broad application prospect in emerging fields such as biometrics, smart driving, robotics, smart home, smart TV, smart security, 3D modeling, face recognition and VR/ARs, which will provide new market growth points for gallium arsenide substrates.

Currently, the laser industry is developing rapidly around the world. With the development of global intelligence, the demand for lasers in smart devices, consumer electronics, new energy and other fields continues to grow, as well as the continuous expansion of emerging application fields such as medical and beauty equipment, the size of global laser market will continue to maintain stable growth, and will also bring a significant driving effect to the GaAs substrate market.

As a whole, indium phosphide substrate, as the basic material for optical module chips and laser sensor chips, and gallium arsenide substrate, as the basic material for LED red pixel light-emitting chips, radio frequency devices and laser chips, are irreplaceable. According to the statistics of professional market research institutions, the main downstream application markets of indium phosphide and gallium arsenide substrates have been relatively prosperous in the past five years, and the strong demand for downstream applications will also drive the market of indium phosphide and gallium arsenide substrates to grow rapidly.

3) Future development trend of GaAs substrate

Doing well out of the strong demand for RF devices and optoelectronic devices in LED and mobile communication RF, GaAs substrate is expected to maintain high growth in the sales in the near future. Currently, the downstream application market of GaAs substrate mainly includes RF and LED. According to Yole's estimation, the global market size of downstream RF devices of GaAs substrate will reach 25 billion USD in 2025. The global market size of downstream LED devices will exceed 180 billion USD according to GGII data, with a very broad downstream market space of GaAs substrate. For specific applications, the rapid penetration of Mini LED, Micro LED, 5G cell phones, and VCSEL visual recognition will significantly pull GaAs substrate market to a higher level.

In the LED display field, Mini LED and Micro LED chips used in new generation display are sub-millimeter and micron levels, which require high technology for GaAs substrate. Therefore, new opportunities will be offered for gallium arsenide application with the popularity of Mini LED and Micro LED. Based on Yole's forecast, the demand for GaAs substrate by Mini LED and Micro LED devices is in a rapid growth. The global market sales of GaAs substrate (equivalent to two inches) for Mini LED and Micro LED devices will increase from 2.0790 million pieces in 2019 to 6.138 million

8-1-1-101

pieces in 2025, with a compound annual growth rate of 19.77%. In 2019, the global market size of GaAs substrate for Mini LED and Micro LED devices was about USD17 million. The global market size of the GaAs substrate is expected to reach USD70 million by 2025, with a compound annual growth rate of 26.60%. At present, lead enterprises of Mini LED chips have basically completed the investment layout in Mini LED.

In the RF field, gallium arsenide will still dominate the market of 5G smartphone PA (RF power amplifier). According to Yole's statistical forecast, the RF device market alone accounted for 30.15% of the total overall gallium arsenide semiconductor market in 2021, and contributed 32.50% of the output value. According to the statistics of Orient Securities Institute, each cell phone needs to use 7 PAs on average in 4G era. As 5G has added new frequency bands, new high frequency bands will be needed in the future. 5G needs to continue to be compatible with 4G, 3G and 2G standards. Therefore, 5G cell phones will need more PAs, up to 16 PAs. The average of PAs is expected to be more than 10. RF devices based on gallium arsenide are expected to further promote the penetration rate of mobile terminals in the 5G era.

In terms of 3D sensors, with Apple's launch of iPhoneX with integrated face recognition structured light front camera in 2017, Apple commercialized 3D sensors (vertical-cavity surface-emitting laser, VCSEL) in cell phones. Huawei, OPPO, ViVO, Xiaomi, Samsung and other cell phone manufacturers are subsequently expected to gradually equip 3D sensors (vertical-cavity surface-emitting laser, VCSEL) in cell phones. Cell phones are only one of the application scenarios of VCSEL. With the development of intelligent driving, automotive LiDAR is expected to provide a new growth space for GaAs substrates. According to McKinsey & Company, automobiles achieve the annual production volume that will reach 115 million units by 2030, of which 15% will achieve advanced autonomous driving and 45% will achieve low-level autonomous driving. In 2019, the global sales in GaAs substrate (equivalent to two-inch) of VCSEL devices are about 938,900 pieces, and are expected to grow to 2,993,200 pieces by 2025, with a compound annual growth rate of 21.32%. The global market size of GaAs substrate of VCSEL devices is about USD21 million in 2019. The global market size of GaAs substrate is expected to exceed USD56 million by 2025, with a compound annual growth rate of 17.76%.

4) Future development trend of InP substrate

The rapid development of 5G communication, big data and cloud computing will bring new opportunities. According to Yole's estimation, the market size of the downstream devices of InP substrate will exceed USD17 billion in 2025. Driven by

8-1-1-103

market demand and the continued favorable policies such as "East Digital and West Computation", the downstream market of InP substrate will still have a sound development trend. 5G communications, big data and cloud computing are inseparable from the optical modules. InP substrate is a key semiconductor material for lasers and receivers of optical module components. Therefore, the construction for 5G base stations and data centers demonstrates a great growth point of the market of InP substrate.

In the field of optical communications, the use of optical modules for 5G base stations is significantly higher than that of 4G base stations, with the large-scale rollout of 5G base station construction, will greatly drive the growth of demand for optical modules. According to Yole's statistics, InP substrate (equivalent to two inches) of optical module devices is expected to sell more than 1 million pieces globally by 2026. The period from 2019 to 2026 witnesses a compound annual growth rate of 13.94%. The global market size of InP substrate of optical module devices is expected to USD157 million in 2026, with a compound annual growth rate of 13.94% from 2019 to 2026. In addition, the biggest advantage of indium phosphide is that it has higher power density than gallium arsenide. RF devices made of indium phosphide are more effective than gallium arsenide RF devices in the 5G millimeter wave band and B5G (Beyond 5G) sub-terahertz (THz) band. In the future, indium phosphide is expected to become the upstream base material for communication RF devices in the 6G era.

In the field of data centers, with the popularity of mobile Internet in recent years, data traffic is growing rapidly, driving the booming of cloud computing industry, stimulating the growth of demand in data center, and driving the growth of demand for data centers' optical modules. According to Yole's statistics, the global market size of optical modules of data centers will rise from USD4 billion in 2019 to USD12.1 billion in 2025, with a growth at a compound annual growth rate of 20% from 2019 to 2025.

Moreover, indium phosphide, as a basic raw material for the Digital Infrastructure Mega Project 'East-West Data Migration', will also have more market growth space. On February 17, 2022, NDRC, Cyberspace Administration of Office, Ministry of Industry and Information Technology of PRC, and National Energy Administration jointly issued a notice, agreeing to build 8 national computing hubs in the Beijing-Tianjin-Hebei region, the Yangtze River Delta, the Guangdong-Hong Kong-Macao Greater Bay Area, the Chengdu-Chongqing economic circle, north China's Inner Mongolia Autonomous Region, southwest China's Guizhou Province, northwest

8-1-1-104

China's Gansu Province and Ningxia Hui Autonomous Region, and approve plans on 10 national data center clusters, indicating a strategy is in full swing to channel more computing resources from the eastern areas to the less developed western regions . The 8 computing hubs will promote data circulation and value transfer from the eastern areas to the less developed western regions, and facilitate the shift of data center-related industries from east to west. These 10 national data center clusters will be responsible for the development of the large and super-large data centers of the 8 computing hubs. The Project 'East-West Data Migration' will promote the further construction of China's data centers, which in turn will lead to huge demand and growth space for upstream InP substrate.

2. Application or development trend of other materials that have the same or similar functions as gallium arsenide and indium phosphide, the competitive advantages and disadvantages of gallium arsenide and indium phosphide compared with such materials, and the impact of such materials on the competitiveness and future development space of gallium arsenide and indium phosphide

It is difficult for devices manufactured based on conventional silicon materials to guarantee the linearity and stability of integrated circuits in special environments and applications. Therefore, compound semiconductor materials such as gallium arsenide and indium phosphide are required. Other materials with the same or similar functions as gallium arsenide and indium phosphide also include gallium nitride and silicon on

8-1-1-106

insulator.

(1) Application and development trend of gallium nitride

Gallium nitride pertains to wide-bandgap semiconductor material. Wide-bandgap semiconductor material represented by silicon carbide, gallium nitride, has the advantages of large bandgap width, high breakdown electric field, high thermal conductivity, high electron saturation rate and strong radio resistance ability compared with other types of semiconductor materials. Therefore, wide-bandgap semiconductor material is widely used in RF, power devices and other fields because of its excellent performance to adapt to high voltage, high frequency and high temperature environment.

At present, silicon-based materials are still the main materials for the production of semiconductor chips and devices around the world. Wide-bandgap semiconductor material, represented by silicon carbide and gallium nitride, is rapidly rising because of its advantages with the advent of the Internet of Things and the 5G era. Wide-bandgap semiconductor material has become an important part of the "new infrastructure" strategy of China, and the Outline of the 14th Five-Year Plan includes "the development of gallium nitride such as silicon carbide and wide-bandgap semiconductor" as key support areas. The wide-bandgap semiconductor material device market has large growth space in China, benefiting from the industry development and policy environment.

(2) Application or development trend of SOI

SOI has the advantages of small parasitic capacitance, small short channel effect, high integration density, high speed, low power consumption and simple process. Over the recent years, SOI silicon wafers, driven by the terminal markets such as 5G communications, Internet of Things, artificial intelligence and automotive electronics, with the ecosystem gradually improved, have been widely used in the manufacturing of integrated circuit chips such as RF front-end chips, sensor, power devices and silicon photonic devices through the in-depth cooperation and research and development of

8-1-1-107

upstream and downstream enterprises in industry chain. Among them, radio frequency is the most widely used.

The global sales of SOI market increased from USD537 million to USD915 million from 2017 to 2019, with a compound annual growth rate of 50.55%, according to SEMI statistics. The production process of SOI is more complex as a special silicon-based material, the cost is higher, and the application field is more professional. Only a few enterprises in the world, such as Soitec, Shin-Etsu Chemical, GlobalWafers, SUMCO and NSIG, have the ability to produce SOI. On the demand side, the current production and marketing scale of SOI substrates in China is still relatively small since there are not many enterprises with SOI chip production capacity in Chinese chip manufacturing field.

Other materials that play the same or similar functions as gallium arsenide and indium phosphide mainly include gallium nitride and SOI. For more information on the competitive advantages and disadvantages of gallium arsenide and indium phosphide compared with such materials, and their impact on gallium arsenide, indium phosphide competitiveness and future development space, please refer to Q "I. (I) The application fields and application scenarios of different types (generations) of semiconductor materials. If there is an overlap, please explain the competitive advantages, disadvantages and future development trend according to the requirements of the overlapping areas and scenarios on the functional features of semiconductor materials and the features of the Company's products;".

In the field of compound semiconductor substrates, a company's production capacity of large-size substrates can, to a certain extent, reflect its technical strength. The Company has the technologies at the first echelon level in the world with its main competitors in terms of substrate product size.

The production of III-V compound semiconductor substrates covers multiple complex processes including, among others, poly-crystal synthesis (if any), single-crystal growth, cutting, grinding, polishing, cleaning and testing, with a high technical threshold. Meanwhile, InP and GaAs substrates are gradually iterating to a larger size, which imposes high requirements on enterprises for equipment, process and technology accumulation. As regards the existing products, III-V compound semiconductor

8-1-1-122

substrate enterprises need to keep improving product performance indicators to adapt to the continuous iteration of chip and device products of downstream customers.

Based on the public information of competitors, the main substrate product sizes provided by each relevant company are as follows:

Apart from that, the Company also sends samples of product to the downstream customers for testing, striving to participate in the formulation of future parameter standards for new products, including 6G optical module and mobile phone, Mini LED, Micro LED, VR, AR, L4-L5 lidar and wearable devices, in a bid to dominate the substrate technology and take the lead in seizing emerging market share.

4. The Company's product has excellent performance and good stability with years of iterative accumulation of technology and process

Compared with competitors, the Company has more than 35 years of single-crystal growth experience in vertical gradient freeze method (VGF method), and the grown single crystal has stable quality and reasonable cost control. In order to ensure the yield of product, the downstream epitaxy manufacturer and final device manufacturers will put forward higher requirements for the substrate pit density level of substrate manufacturers in the future. Therefore, the technical level of single-crystal growth directly determines the pit density level. In terms of technical characteristics, the Company has the technology to manufacture low-etching pit density substrate.

One of the major difficulties in producing compound semiconductor substrate materials is to maintain the stability of product, and automatic production is the most effective way to solve the stability of product. However, semiconductor industry has a high barrier, which does not depend entirely on capital investment, but also needs to have a deep understanding of various production processes and downstream applications. Therefore, the automation level of production lines mainly depends on the iterative accumulation of processes and the reserve of engineers. The products of the Company can maximize the use of gallium arsenide and indium phosphide materials.

At present, the Company has unique attainments in crystal growth technology in VGF method. The Company is improving the automation level in wafer processing technology. At present, it has developed a fully automatic wafer thinning process and a fully automatic wafer wet cleaning process, and is developing a fully automatic wafer chemical mechanical polishing process. In the future, the Company will continue to improve the automation level of the whole process and further improve the stability, reliability and yield of the whole process while ensuring the stable application quality of customer products.

To sum up, the Company's production technology is stable and highly automated. The product has the advantages of low dislocation density, high electron mobility, good surface consistency and low fluctuation value of total thickness. The product has superior performance, stable parameters and high cost performance.

I. Explanations from the Issuer

(I) The impact of being included into the list of hazardous chemicals on the Company's operation. Whether other major products of the Company, in addition to gallium arsenide, are included in the list

1. Impact of being included into the list of hazardous chemicals on the Company's operation

On February 27, 2015, the State Administration of Work Safety issued the Catalogue of Hazardous Chemicals (2015 Edition), which lists gallium arsenide as a hazardous chemical. The impact of these circumstances on the Company's operations is as follows:

(1) In terms of industrial policy

According to the Catalogue of Industrial Structure Adjustment Guidance (2019 Edition) promulgated by the National Development and Reform Commission, the production and operation of GaAs engaged by the Company does not belong to the restricted or eliminated industry in the Catalogue; according to Negative List of Market Access (2022 Edition) promulgated by National Development and Reform Commission and Ministry of Commerce, the Company's gallium arsenide production and operation business does not belong to the prohibited access category in the List. Therefore, after gallium arsenide was included in the list of hazardous chemicals, the relevant business of the Company complies with relevant national industrial policies, and the production capacity of gallium arsenide products of the Company was not restricted by the relevant national industrial policies.

(2) In terms of business qualification

According to Article 67 of the Regulations on the Safety Management of Hazardous Chemicals, the production enterprises and import enterprises of hazardous

8-1-1-127

chemicals shall register the hazardous chemicals with the organization responsible for the registration of hazardous chemicals in the Work Safety Supervision and Administration Department of the State Council. According to the provisions of Article 14 of the Regulations, the production enterprises of hazardous chemicals shall obtain the safe production license of hazardous chemicals in accordance with the Regulations on Safe Production License before production. According to the provisions of Article 33 of the Regulations, the State implements a licensing system for the operation of hazardous chemicals. Without permission, no entity or individual may operate hazardous chemicals; a legally established hazardous chemical production enterprise does not need to obtain a hazardous chemical business license to sell the hazardous chemicals produced by the enterprise within its plant area.

As per the above regulations and requirements, after gallium arsenide was listed in the Catalogue of Hazardous Chemicals (2015 Edition), Chaoyang Tongmei has obtained the Registration Certificate of Hazardous Chemicals and the Safe Production License in accordance with relevant laws and regulations, and does not need to obtain the hazardous chemicals business license for the product sold within its plant area.

(3) In terms of marketing

During the reporting period, sales revenue and sales volume of gallium arsenide substrate materials of the Company are as follows:

Gallium arsenide was included in the list of hazardous chemicals in relatively early time, and no restriction has been imposed on procurement at related downstream applications since the policy was introduced. During the reporting period, the sales revenue and sales volume of gallium arsenide substrate materials of the Company maintained steady growth. The inclusion of gallium arsenide in the list of hazardous

8-1-1-128

chemicals did not have material adverse effect on the sales revenue and sales volume of gallium arsenide substrate materials during the reporting period. At the same time, in the downstream application field, there is no situation where it is unable to purchase gallium arsenide substrate products from the Company due to policy restrictions and other factors.

(4) In terms of operating costs

Due to inclusion of gallium arsenide in the list of hazardous chemicals, the Company has to further strengthen its own safety production management, and increase investment in environmental protection, which puts forward higher requirements for its production and inventory management, and increases its operating costs to a certain extent, but the overall impact is relatively small.

In conclusion, the inclusion of gallium arsenide in the list of hazardous chemicals will not have a material adverse impact on the Company's sustainable operation ability.

2. Whether other major products of the Company, in addition to gallium arsenide, are included in the list

The Company's major products include InP substrate, GaAs substrate, germanium substrate, high-purity gallium, gallium-magnesium alloy, indium-magnesium alloy, PBN crucible and other PBN materials. Gallium has been listed in the Catalogue of Hazardous Chemicals in 2003, in addition to that gallium arsenide was listed in the Catalogue of Hazardous Chemicals in 2015. Chaoyang Jinmei, the controlled subsidiary of the Company, is responsible for the production of high-purity gallium products. Chaoyang Jinmei has obtained the Registration Certificate of Hazardous Chemicals and the Safe Production License in accordance with relevant laws and regulations, and does not need to obtain the hazardous chemicals business license for the product sold within its plant area.

slightly lower than those to regular employees in the same position, mainly due to the high mobility as well as the short service term, probation period and overtime working hours in production auxiliary positions of dispatched employees. In 2019, the average remunerations to dispatched workers were higher than those to regular employees in the same position, mainly caused by the higher proportion of employees in catering and cleaning positions with lower remuneration level to the regular employees in the same position in 2019.

It can be seen from the above table that during the reporting period, there is no significant remuneration difference between dispatched employees and regular employees in the same position, and the use of dispatched employees by the Company has no material impact on the human resource costs of the Company.

Q6. History of the Issuer

6.1

According to the submissions, Beijing Tongzhou District Industrial Development Zone Corporation (hereinafter referred to as "Industrial Development Zone Corporation") and AXT jointly established Tongmei Limited, the Issuer's predecessor, in 1998. In 2001, Industrial Development Zone Corporation transferred its equity interests to AXT, thereby exiting from the Issuer. Industrial Development Zone Corporation was an enterprise owned by the whole people. According to the then applicable provisions, Industrial Development Zone Corporation should conduct an asset appraisal when it exited from Tongmei Limited and obtain a confirmation notice from the competent state-owned assets administration authorities in charge of examination and approval matters, or file the appraisal result with the competent state-owned assets administration authorities. Upon the verification by the intermediary agency, as it occurred a long time ago, the archival materials in relation to the equity transfer auditing appraisal and the receipt of equity transfer price have not been found.

Asset appraisal, and confirmation or filing procedures of appraisal results

Due to the long time span, the death or resignation of the original handlers and other reasons, no relevant archives on the procedures for the transfer of state-owned assets such as appraisal request, asset appraisal and confirmation of amount appraised regarding this equity transfer or the payment for the equity transfer price can be located; in order to solve historical problems, prevent the loss of state-owned assets and support the listing of the Issuer, the underlying equity transfer has been audited and appraised retrospectively according to the procedures and confirmed by the

8-1-1-146

competent authorities, with the transfer price having been settled, which is thus in line with the relevant laws and regulations on the transfer of state-owned assets.

Pursuant to the Administrative Measures on the Appraisal of State-owned Assets (State Council Order No. 91, November 1991) and the Rules on the Implementation of the Administrative Measures on the Appraisal of State-owned Assets (Guo Zi Ban Fa [1992] No. 36) and other applicable provisions, the exit of Industrial Development Zone Corporation from Tongmei Limited shall be subject to an asset appraisal, and is required to obtain a confirmation notice issued by the competent state-owned assets administrative authorities in charge of examination and approval matters, or file the appraisal result with the competent state-owned assets administration authorities.

According to the documents and clarifications from AXT and Industrial Development Zone Corporation, as well as the confirmation by interviewing with relevant principals of the People's Government of Zhangjiawan Town, Tongzhou District, Beijing, the above equity transfer occurred in June 2000. Irrespective of efforts to find informed personnel and search relevant historical files with supports from the competent government authorities, no relevant archives on the procedures for the transfer of state-owned assets such as appraisal request, asset appraisal and confirmation of amount appraised regarding this equity transfer or the payment for the equity transfer price can be located due to the long time span, the death or resignation of the original handlers and other reasons, with defects thereon.

In view of the above, to solve historical problems, prevent the loss of state-owned assets and support the listing of the Issuer, relevant government departments of Tongzhou District have, under the organization of the People's Government of Zhangjiawan Town, Tongzhou District, Beijing, jointly approved the implementation of retroactive audit and evaluation procedures on the above matters (taking May 31, 2000 as the base date), and determined that the People's Government of Zhangjiawan Town, Tongzhou District, Beijing and the Tongzhou Management Committee of Zhongguancun Science Park (i.e. the Park Management Committee of the People's Government of Tongzhou District, Beijing) shall jointly confirm the retrospective audit

8-1-1-147

and appraisal results, and issue corresponding supporting materials according to the listing-related audit requirements.

Tihuasic (Beijing) Certified Public Accountants Co., Ltd. and Tianhua Xiangtong (Beijing) Assets Appraisal Co., Ltd. respectively issued Tihuasic's Audit Report of Beijing Tongmei Xtal Technology Co., Ltd. (Tianhua Zhengxin (2022) Shen Zi No. N006) and the Retrospective Assets Appraisal Report of All Interests of Shareholders in Beijing Tongmei Xtal Technology Co., Ltd. Involved by the Equity Value Intended to be Known by Beijing Tongzhou District Industrial Development Zone Corporation and Beijing Tongmei Xtal Technology Co., Ltd. (Tianhua Xiangtong (2022) No. 2-1). According to the retrospective audit and appraisal results, as of May 31, 2000, the value of equity interests of shareholders in Beijing Tongmei is RMB48.24 million; as calculated based on 1% equity interest, the value of equity interest held by Industrial Development Zone Corporation in Beijing Tongmei is RMB482,400. Upon the mutual agreement between Industrial Development Zone Corporation and AXT and the confirmation by entering into a written supplementary agreement, AXT shall pay Industrial Development Zone Corporation a sum of RMB1,101,686 in principal and interest for the equity transfer, the sum of which has been fully paid as of the date hereof.

In March 2022, the superior competent authorities of Industrial Development Zone Corporation i.e. the People's Government of Zhangjiawan Town, Tongzhou District, Beijing and the Tongzhou Management Committee of Zhongguancun Science Park jointly issued a Statement of Fact, confirming that "the appraisal method and result as used by the retrospective appraisal are reasonable, and accordingly, the equity transfer price is determined to be RMB482,400. Industrial Development Zone Corporation has received the equity transfer price and interest thereof, totaling RMB1,101,686 in full"; "Industrial Development Zone Corporation has performed the retrospective appraisal procedure for its exit from Tongmei Limited, and the transfer price has been paid in full in compliance with relevant laws and regulations on the transfer of state-owned assets, without any damage to the legitimate rights and interests of the state, the collective and other third parties, and without any dispute or potential risk."

8-1-1-148

Zhangjiawan Town, Tongzhou District, Beijing, it is confirmed that Industrial Development Zone Corporation exited from the Issuer in accordance with a complete procedure, the equity transfer being true and effective.

In conclusion, the exit of Industrial Development Zone Corporation from Tongmei Limited has performed such procedures as the decision-making of the board of directors of Tongmei Limited, the approval of the Beijing Tongzhou District Foreign Economic and Trade Commission and the industrial and commercial change procedure. The defects of failure to locate relevant archives on the procedures for the transfer of state-owned assets such as appraisal request, asset appraisal and confirmation of amount appraised regarding such equity transfer and the payment for the equity transfer price have been rectified by the entities involved having performed the retrospective appraisal procedures and obtained the confirmation from the competent authorities, and the transfer price has been settled, which is in compliance with the applicable laws and regulations on the transfer of state-owned assets.

(II) Impact of the failure to find the documents in relation to the auditing appraisal and transfer price on the validity of the equity change

According to the requirements on this offering and listing, AXT and the Issuer have applied to Industrial Development Zone Corporation for confirming the fact of the equity transfer. Industrial Development Zone Corporation issued a Statement of Fact in December 2021, confirming that "Industrial Development Zone Corporation invested in and became a shareholder of Tongmei Limited in August 1998, and entered into the Equity Transfer Agreement with AXT, Inc. in June 2000, thereby transferring all shares held in Tongmei Limited to AXT, Inc., and the approval and industrial and commercial change procedures have been completed with Beijing Tongzhou District Foreign Economic and Trade Commission, AXT, Inc. therefore became the sole shareholder of Tongmei Limited".

8-1-1-149

Development Zone Corporation i.e. the People's Government of Zhangjiawan Town, Tongzhou District, Beijing and the Tongzhou Management Committee of Zhongguancun Science Park jointly issued a Statement of Fact in March 2022, confirming that "Industrial Development Zone Corporation has performed the retrospective appraisal procedure for its exit from Tongmei Limited, and the transfer price has been paid in full in compliance with the relevant laws and regulations on the transfer of state-owned assets, without any damage to the legitimate rights and interests of the state, the collective and other third parties, and without any dispute or potential risk". According to the interviews with relevant persons in charge of the People's Government of Zhangjiawan Town, Tongzhou District, Beijing, it is confirmed that Industrial Development Zone Corporation exited from the Issuer in accordance with a complete procedure, the equity transfer being true and effective.

HE Junfang intended to accept transfer of the equity in Beijing Boyu held by Ulrich Goetz and the equity in Beijing Bomeilian held by MA Jie through Zhongke Hengye under his control (HE Junfang held 79% of its property share and acted as the appointed representative of its executive partner).

In order to fund the equity transfer price, Zhongke Hengye borrowed a total of USD8.05 million (or RMB52.655928 million) from Liaoning Zhuomei, an external institutional investor, for which an agreement has made whereby Zhongke Hengye shall repay the loan with its corresponding equity in Beijing Tongmei.

At the end of 2020, Zhongke Hengye and Ulrich Goetz entered into the Equity Transfer Agreement, by which Ulrich Goetz transferred the registered capital, in an amount of USD141,180, held by him in Beijing Boyu to Zhongke Hengye at a price of USD2.4 million. Besides, Zhongke Hengye entered into the Transfer Agreement with Ma Jie, by which Ma Jie transferred 33.33% equity interest held by him in Beijing Bomeilian (corresponding to the registered capital of RMB660,000) to Zhongke Hengye at a price of RMB27.73 million. In January 2021, Zhongke Hengye transferred the registered capital in an amount of RMB10,463,911 held by it in Beijing Tongmei to Liaoning Zhuomei with reference to the share purchase price of RMB5.03/registered capital for external investors, and Zhongke Hengye has repaid the debt to Liaoning Zhuomei by equity accordingly.

2. Beijing Bomeilian

Before the asset restructuring of the Company in December 2020, both Zhongke

8-1-1-154

Hengye and Beijing Bomeilian were shareholders of Beijing Boyu, holding 6% and 27% equity interest in Beijing Boyu respectively. In December 2020, Beijing Bomeilian and Zhongke Hengye respectively subscribed for the Issuer's newly increased registered capital with their equity interest in Beijing Boyu as payment consideration. Such asset restructuring obliged Beijing Bomeilian and Zhongke Hengye to pay various taxes including enterprise income taxes. To fund the taxes, Beijing Bomeilian transferred its registered capital in an amount of RMB4,907,343 held in Beijing Tongmei to AXT in January 2021 at a price of RMB equivalent of USD3.73 million.

In conclusion, the transfer of equity interest in the Company by Zhongke Hengye and Beijing Bomeilian soon after they invested in the Issuer was to repay the external borrowings and fund taxes and charges involved in asset restructuring.

(II) Fairness of the share price paid by Zhongke Hengye and Beijing Bomeilian for their investment in the Company, and the reasons for and reasonableness of the large gap in prices.

In December 2020, to solve horizontal competition and integrate business resources, the Company carried out the asset restructuring and acquired 100% equity interest in Beijing Boyu, Baoding Tongmei, Chaoyang Tongmei, Nanjing Jinmei and Chaoyang Jinmei, among which, Beijing Bomeilian, with its 27% equity interest in Beijing Boyu, and Zhongke Hengye, with its 6% equity interest in Beijing Boyu, subscribed for the newly increased registered capital of the Company and realized their capital increase in the Company by way of share exchange; the price at which Zhongke Hengye and Beijing Bomeilian purchased the shares of the Issuer through such asset restructuring is consistent with the price at which AXT, Jinchao Business Management and other shareholders participated in the capital increase by way of share exchange, both of which were RMB1.36 per unit of registered capital. The price was determined through the negotiation among the parties on the basis of the net asset value per share of Beijing Tongmei and was fair.

In January 2021, for the purpose of repaying the external borrowings and funding the taxes and charges involved in the asset restructuring, Zhongke Hengye and Beijing Bomeilian transferred part of equity interest held by them in the Company to Liaoning

8-1-1-155

Zhuomei and AXT respectively, and the transfer price is the same as the price at which Haitong Innovation, Haitong New Energy, Anxin Industrial Investment, Huadeng II and other external investors purchased the shares of the Company in the same period, both of which were RMB5.03 per unit of registered capital. Such transfer price was determined through the negotiation between both parties to the relevant transfer with reference to the price at which external institutional investors purchased the shares in the same period, the large gap between such transfer price and the above share price in the asset restructuring is reasonable.

The specific reasons for the significant difference in the share price and transfer price between Zhongke Hengye and Beijing Bomeilian can be referred to Q1 "I.(I).4 The reason and reasonableness of large difference between the valuation at this asset restructuring of the Company and the valuation at the capital increase from third parties in January 2021" hereof.

In conclusion, the price at which Zhongke Hengye and Beijing Bomeilian purchased the shares of the Issuer through the asset restructuring was determined through the negotiation among the parties on the basis of the net asset value per share of Beijing Tongmei and was fair; the price at which Zhongke Hengye and Beijing Bomeilian transferred part of equity interest held by them in the Company to Liaoning Zhuomei and AXT was determined through the negotiation between both parties to the relevant transfer with reference to the price at which external institutional investors purchased the shares in the same period, the large gap between such prices is reasonable.

From February 2018 to May 2019, AXT signed a Equity Exit Agreement with FAN Jiahua, FENG Yi and ZONG Hongxia (ZHANG Fengxiang, the husband of ZONG Hongxia, was passed away at the time of equity exit) respectively, pursuant to which all nominee holding was canceled.

According to the statement of AXT and the confirmation by interviewing with the entrusting holders namely FAN Jiahua, FENG Yi and ZONG Hongxia, at the time of the establishment of Nanjing Jinmei, FAN Jiahua served as the general manager and ZONG Hongxia served as the deputy general manager, ZHANG Fengxiang served as the executive director and financial director, and FENG Yi served as a consultant in Nanjing Jinmei. To motivate the above persons, AXT transferred a total of 5% equity interest in Nanjing Jinmei to FAN Jiahua, FENG Yi, ZONG Hongxia and ZHANG

8-1-1-160

Fengxiang in September 2000, as Nanjing Jinmei was incorporated as a Sino-foreign cooperative enterprise, no individual may be a Chinese partner to the enterprise, such part of equity interest was held by AXT on their behalf.

From February 2018 to May 2019, due to the advanced age of FAN Jiahua, FENG Yi and ZONG Hongxia, and Nanjing Jinmei's main production and operation site needed to be relocated to another place, FAN Jiahua, FENG Yi and ZONG Hongxia requested to exit from Nanjing Jinmei and entered into the Equity Exit Agreement with AXT, agreeing to transfer all the equity interest held by them in Nanjing Jinmei to AXT. The above nominee holding has been completely released after consummation of such equity transfer. As of October 2020, FAN Jiahua, FENG Yi and ZONG Hongxia have received all the amounts payable for their equity exit.

(III) Specific meaning of "persons handling the equity exit matter", and whether there is any dispute or potential dispute in the establishment and termination of the nominee holding

According to the interviews with HAO Ze, the deputy general manager and chief financial officer of the Issuer (who worked in the finance department of Nanjing Jinmei from September 2000 to March 2005) and CHEN Yu, a financial manager of Nanjing Jinmei, the specific matter that FAN Jiahua, FENG Yi and ZONG Hongxia exited from Nanjing Jinmei was handled by HAO Ze and CHEN Yu, and thus HAO Ze and CHEN Yu are the persons handling the equity exit matter.

To sum up, according to the confirmation by interviewing with all the entrusting holders FAN Jiahua FENG Yi and ZONG Hongxia other than the deceased ZHANG Fengxiang, as well as HAO Ze and CHEN Yu, the persons handling the equity exit matter, and upon search through public network, there is no dispute or potential dispute in the establishment and termination of the nominee holding.

II. The Issuer's Attorney is requested to verify and issue a clear opinion on the above issues.

The Issuer has revised the relevant description on "satisfaction by the Company with the requirements of science and innovation attribute" in the Prospectus..

7.2

According to the submissions, AXT has entered into certain cross-license agreement with one of its major competitors to grant each other's patents filed before December 31, 2029 to the other party and its controlled entities for use. AXT shall pay a royalty (actually borne by the Issuer) and the counterparty is exempt from it. The cross-license agreement was signed primarily to avoid any risk of infringement or litigation arising from overlapping patents, and the Issuer has not yet applied the counterparty's licensed patents to its existing products.

Please indicate the reasons and reasonableness for the counterparty to be exempted from payment of the royalty while it is payable by the Issuer to the counterparty even if the counterparty's licensed patents are not actually applied to the Issuer's existing products.

Reply:

I. Explanations from the Issuer

On April 16, 2020, AXT and M signed a Cross-License and Non-Litigation Agreement, providing that M and AXT shall license to each other and the controlled entities thereof any patent filed by them prior to and including December 31, 2029, and that during the licensed term of such patents, M and AXT and their controlled entities will not knowingly pursue litigation worldwide against each other and each other's direct or indirect customers for any direct or indirect patent infringement resulting from

8-1-1-165

such license. Pursuant to the agreement, M shall be free from paying royalties, while AXT shall pay royalties to M, for the reasons and with the rationality as follows:

On the one hand, the number of patents licensed by M, who was established and started the patent layout at an earlier time having a high status in the industry, to AXT is far greater than that by AXT to M; and on the other hand, it has formed a relatively complete and comprehensive patent network layout in the field of semiconductor substrate materials in the early stage, with a certain first mover advantage. Additionally, the Company keeps a large number of formula and process know-how strictly confidential according to different types of core technologies, in addition to applying for intellectual property rights at home and abroad, so as to avoid disclosing technical secrets due to patent disclosure.

In order to avoid any risk of patent infringement or litigation and to achieve the purpose of non-litigation by both parties, they entered into a Cross-License and Non-Litigation Agreement specifying that M shall be exempt from paying any royalties which shall, nevertheless, be payable by AXT to M.

To sum up, the arrangement is mutually agreed upon by AXT and M after multiple rounds of commercial negotiations and taking into account the historical disputes, industry status, number of patents, patent network layout time and business prospects, which is commercially reasonable as it helps AXT and the company avoid any risk of patent infringement and litigation and conforms to industry practices.

1. Different customers had great differences in product parameter requirements, in response to which the Company needed to dope iron, sulfur and other substances to establish the product performance during production, resulting in different unit consumption of raw materials for each single product;

2. The products had different thicknesses and edge angles to meet different customer needs, leading to different unit consumption of raw materials for products;

3. Affected by production factors such as field temperature control and personnel operation proficiency, there were losses for each product at varying degrees in the production process;

Note: The discrepancy rate is calculated by (actual value - theoretical value) / actual value, the same below

1) Longitudinal comparison

During the production of InP polycrystal, the unit consumption of red phosphorus and high-purity indium was relatively stable as a whole, with a normal phenomenon of slight fluctuation in each year. In 2020, the unit consumption of high-purity indium was 0.83, which was relatively low, mainly due to the fact that some InP polycrystal products were still in production in 2019 and 2021. After considering such factor, the unit consumption of high-purity indium in 2019 and 2021 would be 0.85, with a small discrepancy rate of 2.35% compared with 2020.

During the reporting period, the unit consumption of InP polycrystal required for the production of InP substrate was relatively stable.

2) Comparison with theoretical value

8-1-1-190

During the reporting period, the unit consumption of InP polycrystal was basically consistent with the theoretical value. The unit consumption of high-purity indium required for the production of InP polycrystal showed a certain discrepancy from the theoretical value, while the unit consumption of red phosphorus had a substantial discrepancy from the theoretical value.

The main reasons for the loss of red phosphorus lie in: 1) after red phosphorus entered the container containing metal indium in the form of gas after evaporation for synthesis, some red phosphorus adhered to the inner wall of the container without participating in product synthesis; 2) given the relatively uneven synthesized InP polycrystal, in order to meet the requirements of standard carrier concentration (which refers to the number of charges that can move freely in unit volume, the higher the carrier concentration, the better the conductivity), part of the InP polycrystal needed to be removed, and the removed part would be placed in a high temperature to gasify phosphorus, and then subject to leaching to form wastewater containing phosphoric acid for further treatment; 3) after InP polycrystal was produced into ingots, they needed to be polished or otherwise treated, as a result of which, the ingots in qualified finished products would has a smaller weight than the ingots discharged.

The main reason for the loss of metal indium was also that ingots would, after being produced from InP polycrystal, need to be polished and made other treatments, resulting in a weight of ingots in qualified finished products being smaller than that of ingots discharged, and causing the loss of some metal indium.

In conclusion, for the above reasons, the actual unit consumption of red phosphorus and the actual unit consumption of metal indium were higher than the theoretical value, of which the actual unit consumption of red phosphorus had more discrepancy from the theoretical value.

In addition, as per the public paper titled Synthesis, Growth and Characteristics of InP Crystals (a doctoral dissertation written by SUN Niefeng of Tianjin University), 4-6kg InP polycrystal can be synthesized by putting 1-1.4kg red phosphorus and 3-5kg high-purity indium into the InP polycrystal synthesis process. Based on such proportion, the theoretical unit consumption of red phosphorus is 0.17-0.35, and the unit

8-1-1-191

consumption of high-purity indium is 0.5-1.25; while according to the upper limit of the interval, the theoretical unit consumption of red phosphorus is 0.25 and the unit consumption of high-purity indium is 0.83. There is little discrepancy between the Company's actual consumption and its theoretical consumption.

1) Longitudinal comparison

During the reporting period, the unit consumption of high-purity arsenic and high-purity gallium required for the production of GaAs polycrystal was relatively stable.

As one of the main raw materials for the production of GaAs substrates, high-purity gallium is obtained by the Company through purification from gallium. The unit consumption of gallium in 2020 was slightly higher, mainly because, on the one hand, Nanjing Jinmei relocated its production line in 2019 to Chaoyang Jinmei in 2019, and the production process was gradually debugged and restored in 2020, thereby resulting in a large consumption; on the other hand, high-purity gallium with higher purity at 7N level produced in 2020 accounted for a relatively high proportion of 79.57%, representing an increase of 70.68% compared with that in 2019, and its unit consumption of gallium was relatively high, thereby increasing the whole unit consumption of gallium.

The unit consumption of GaAs polycrystal was relatively stable in 2019 and 2020, and was increased slightly in 2021 mainly because: on the one hand, the output of 6-inch GaAs substrates increased by 5.49% year on year, resulting in relatively high consumption of GaAs polycrystals given the relatively thick large-size products; on the

8-1-1-193

other, a large number of local employees from Chaoyang, Liaoning and Baoding, Hebei with contemplatively lower operation proficiency were recruited in 2021 due to the re-commissioning and expansion of the GaAs production line after relocation, resulting in the high consumption.

2) Comparison with theoretical value

During the reporting period, there was little discrepancy in the actual unit consumption of high-purity arsenic and that of high-purity gallium required for the production of GaAs polycrystal.

The actual unit consumption of GaAs polycrystals required for the production of each 10,000 pieces of 2-inch GaAs substrates had a relatively great discrepancy from the theoretical consumption. The main reason lies in the fact that the theoretical data was obtained according to the relevant production steps of 2-inch GaAs substrate, while the actual output was made according to the results of various sizes thereof after being converted into 2 inches, and generally the large-size products were relatively thicker requiring the consumption of more raw materials, resulting in a relatively high actual consumption. Based on the output of GaAs substrate of various sizes after they are converted into 2 inches during the reporting period, and in light of the theoretical consumption, it is concluded that the unit consumption of GaAs polycrystal required for the production of each 10,000 pieces of 2-inch GaAs substrate is 146.93kg, with less discrepancy from the actual unit consumption.

18.30%

During the reporting period, the unit consumption of germanium ingot for the production of germanium substrate was basically stable, which was slightly higher in 2020 mainly due to the fierce competition in the downstream market of germanium substrate with higher requirements from the Company's downstream customers for the dislocation density of products that year, resulting in the increase of germanium ingot loss in the production process for the sake of meeting the low dislocation density requirements of substrate products.

The actual unit consumption of germanium ingot required for the production of each 10,000 pieces of 2-inch germanium substrate had a relatively great discrepancy from the theoretical consumption, mainly because the theoretical data was obtained according to the relevant production steps of 2-inch germanium substrate, while the actual output was made according to the results of various sizes thereof after being converted into 2 inches, under which circumstance, given generally the large-size products were relatively thicker requiring the consumption of more raw materials, and the most of germanium substrate materials had a size of 4 inches, the revenue from products of which size accounted for 80.85%, 74.18% and 88.63% respectively during the reporting period, the actual consumption of germanium ingot was relatively high accordingly. Based on the output of germanium substrate of various sizes after they are converted into 2 inches during the reporting period, and in light of the theoretical consumption, it is concluded that the unit consumption of germanium ingot required for the production of each 10,000 pieces of 2-inch germanium substrate is 61.83kg, with less discrepancy from the actual unit consumption.

8-1-1-195

4. PBN crucible

The PBN crucible of the Company was produced by its subsidiary Beijing Boyu using boron trichloride as the main raw material. Given PBN crucibles are mainly customized with different shape, size, performance and purpose and complex shape types, the unit consumption of raw materials for them is unstable having no comparability.

5. High-purity gallium

High-purity gallium is both the product directly sold by the Company and the material for synthesizing GaAs polycrystal and further producing GaAs substrate, with its main raw material being metal gallium. The articulation between the purchase volume and inventory balance of metal gallium, on the one hand, and the output of high-purity gallium, on the other, during the reporting period can be referred to in "I.(II).2. High-purity arsenic, metal gallium, GaAs polycrystal" under this Q9.

(III) The reasons why the purchase unit price of gallium increased year by year during the reporting period, and the impact of the fluctuation of the purchase unit price on GaAs substrate and the Company's total costs and gross margin;

1. The reasons why the purchase unit price of gallium increased year by year during the reporting period

In the past two years, the prices of industrial raw materials have posed a general upward trend due to the domestic economic environment and COVID-19 pandemic. Gallium is extracted from bauxite ore. Due to the market environment of industrial raw materials, the price of gallium has risen sharply since the second half of 2020. According to Asian Metal's statistics, the average ex-factory price of gallium during the reporting period is shown in the figure below:

Unit: RMB/kg

8-1-1-196

During the reporting period, the average purchase unit price of gallium was RMB896.50 per kg, RMB1,010.25 per kg and RMB1,823.03 per kg respectively, which were consistent with market price fluctuations.

2.The impact of the fluctuation of the purchase unit price on GaAs substrate and the Company's total costs and gross margin

Judging from raw materials, the production of gallium arsenide mainly consumes gallium, high-purity arsenic, quartz materials, crucibles for crystal growth (mainly produced from boron trichloride and liquid nitrogen), chemical reagents, packaging materials and other materials. Taking 2021 as an example, subject to other conditions remaining unchanged, the sensitive impact of the purchase unit price of gallium increasing/decreasing by 10% and 20% on GaAs substrates and the Company's total costs and gross margin in 2021 is analyzed as follows:

(IV) The demand and purchase of raw materials after the self-production of indium phosphide polycrystalline;

For the purpose of self-producing indium phosphide polycrystalline, the Company needs to purchase red phosphorus and high-purity indium. The Company's purchase amount for red phosphorus and high-purity indium and the proportion thereof in the total purchase amount during the reporting period are as follows:

During the reporting period, the overall purchase amount for red phosphorus and high-purity indium increased year by year. On this regard, the purchase amount for red phosphorus decreased significantly in 2021, mainly because the Company reduced the purchase for the period based on its own inventory and production arrangement in response to the large number of red phosphorus unused at the beginning of the period;

8-1-1-198

while the purchase amount for high-purity indium was relatively low in 2020, mainly due to the decline of the purchase unit price in that year compared with 2019.

(V) The basic information of the purchase of other raw materials other than the main raw materials, including their type and production purposes.

During the reporting period, in addition to purchasing high-purity arsenic, gallium, indium phosphide polycrystalline, germanium ingot, boron trichloride, quartz materials and other main materials, as well as red phosphorus and high-purity indium, the Company mainly purchased other raw materials, including cutting, grinding and polishing materials, packaging materials, chemical reagents, graphite materials, liquid nitrogen and nitrogen materials and clean consumables. During the reporting period, the purchase amounts of the aforesaid other main raw materials were RMB42,553,500, RMB60,624,300 and RMB65,247,000 respectively, accounting for 24.69%, 22.65% and 16.08% of the total purchase amount respectively, and their production uses are as follows:

(II) The reasons why there are multiple suppliers for the same raw material and whether it conforms to industry practices;

1. The reason why there are multiple suppliers for the same raw material

The Company has a globalized procurement system, established a standardized procurement system, implemented standardized procurement control procedures, and formed long-term mutually beneficial and win-win relationships with suppliers so as to maintain the stable supply of raw materials. The procurement center conducts procurement through quality and price comparison within the scope of qualified suppliers, and follows up and supervises the purchase price in accordance with the relevant regulations. Therefore, the main reasons why there are multiple suppliers for the same raw materials are as follows: (1) the benign competition among suppliers, and the procurement through quality and price comparison is adopted for similar raw materials from different suppliers so as to reduce procurement costs while the quality of raw materials is guaranteed; (2) the multi-channel procurement is adopted to ensure the stability of the sources of supply and to prevent the supply shortage due to the existence of a single supplier.

2. Whether it is consistent with the industry practices

According to P257 of the Reply to the Letter of Inquiry on the Approval of Application Documents of National Silicon Industry Group for the Initial Public Offering of Shares and Listing on the STAR Market to NSIG, "during the reporting period, the Company mainly purchased its key raw material polysilicon from Wacker Group, Hemlock and Marubeni Corporation. In 2016, 2017, 2018 and from January to September 2019, the combined polysilicon procurement amount from the said three companies accounted for 87.35%, 75.73%, 95.51% and 94.45% of the Company's polysilicon procurement amount respectively...".

According to P104 of SICC's Prospectus (Registered Draft), "the Company implements a "A+B+C" model in managing some key materials, of which Category A means the first supplier of such material, which is a leading brand at the international; Category B means the second supplier, which is a leading brand at home or abroad; and Category C means an alternative supplier, which is a newly developed domestic

8-1-1-210

supplier. The Company forms a comprehensive layout of domestic and international suppliers in the said manner so as to reduce the impact of the suppliers, changes in trading policies and other circumstances."

In view of the foregoing, it is reasonable for the Company to have multiple suppliers for the same raw material, and such circumstance is consistent with the industry practices.

(III) The amount and proportion of raw materials imported during the reporting period and whether the corresponding supply is available in China;

The Company's raw materials for production mainly include high-purity arsenic, gallium, indium phosphide polycrystalline, germanium ingot, boron trichloride, quartz material, etc. During the reporting period, the purchase amounts of the aforesaid major raw materials were RMB89,502,800, RMB167,586,100 and RMB276,336,800 respectively, of which the import amounts and proportions involved were as follows:

During the reporting period, the total import amounts of the aforesaid major raw materials were RMB18,588,800, RMB16,680,400 and RMB24,401,100 respectively, and the import proportions were 20.77%, 9.96% and 8.83% respectively, and such amounts and proportions were relatively smaller and decreased year by year. Among them, gallium and boron trichloride were purchased from domestic suppliers; high-purity arsenic, germanium ingots and quartz materials were partially imported.

Indium phosphide polycrystalline was 100% imported from the foreign supplier WAFER TECHNOLOGY LIMITED, mainly because the domestic synthesis process was relatively weaker and cannot guarantee the quality required by the Company; in order to further enhance its competitiveness, reduce the risk of import, and continue to extend to the upstream of the industry chain, the Company has mastered the synthesis technology of indium phosphide polycrystalline and gradually replaced the imported indium phosphide polycrystalline with self-produced indium phosphide polycrystalline.

Up to now, the Company has realized the self-production of InP polycrystal. Corresponding suppliers are available in China for other main raw materials except InP polycrystal.

(IV) Whether the supply of raw materials to the Company is stable as judged in combination with the aforesaid situation.

In combination with the aforesaid situations: 1. The Company has multiple supplies of its main raw materials, and except for indium phosphide polycrystalline, there are two or more suppliers for each of the remaining main raw materials to ensure stable supply; 2. the overall business scale of the aforesaid suppliers is relatively larger, and they have a long history of cooperation with the Company, and there has been a good basis for cooperation and mutual trust; 3. The fact that the Company purchases the same raw material from multiple suppliers is based on its actual situation and

8-1-1-212

business philosophy, and such circumstance is reasonable and meets industry practices; 4. The overall import amounts and proportions of the Company's main raw materials were relatively smaller, and the Company has mastered the synthesis technology of indium phosphide polycrystalline and gradually replaced imported indium phosphide polycrystalline with its self-produced indium phosphide polycrystalline.

In addition, the Company improves its cooperation with raw material suppliers through investment to ensure the stability of raw material supply.

In view of the foregoing, the supply of raw materials to the Company is relatively stable, but there are risks of dependence on some supplies of key raw materials and fluctuations in the prices of raw materials. For relevant details of risk warning and significant matters, please refer to "II. (IV) Risks of Dependence on Some Suppliers of Key Raw Materials and Fluctuations in Prices of Raw Materials" in the "Significant Matters" in the Prospectus and "II. (ii)Risks of Dependence on Some Suppliers of Key Raw Materials and Fluctuations in Prices of Raw Materials" in "Section IV Risk Factors" of the Prospectus.

2. Whether it conforms to the contract and the product delivery process by taking the logistics receipt record, customs declaration form, etc. as the basis for revenue confirmation

Logistics receipt records and customs declaration forms are mainly used for revenue confirmation in direct sales and agency mode: according to the sales orders signed by the Company with different customers and product delivery process, customs declaration forms are used as the basis for revenue confirmation in FOB and CIF mode; the logistics receipt record is used as the basis for revenue confirmation under other modes.

In case of FOB and CIF, the time point of product control transfer occurs when the products cross the ship's rail during sea transportation, or when the products have been handed over to the air carrier or agent during air transportation. Since there is no record carrier for the time point of risk reward/control transfer, it is difficult to determine. The Company believes that when the products are shipped and the customs declaration procedures are completed, it is operable and in line with market practice to take the time point specified in the customs declaration form as the basis for revenue confirmation. Therefore, taking the customs declaration form as the basis for revenue confirmation is in line with the contract and the product delivery process.

In case of CIP, DAP and DDU, etc., the time point of product risk return/control transfer occurs when the product delivery is completed, that is, the time point of revenue confirmation shall be when the product delivery is completed. The Company delivers the products to the customer according to the sales order. At this time, the Company has transferred the risk reward/control right of the goods to the customer to complete its performance obligations, and the sales revenue can be confirmed. The Company usually

8-1-1-217

delivers the products to the delivery place designated by the customer by express. After the goods are signed, the Issuer confirms the customer's receipt of the goods according to the "signed in" displayed in the logistics information of the express bill. Therefore, the logistics receipt record is used as the proof that the customer has completed the sign in, which can be used as the basis for revenue confirmation, and is in line with the contract and product delivery process.

In addition, the Company's products are mainly non standardized products. After delivery of products by the Company to customers, some customers will inspect the products mainly by, among others, checking whether the appearance and quantity of the products are defective, for acceptance. If quality problems are found in the products after they are accepted by the customer, both parties will follow the relevant return procedures of the Company, and the corresponding batch of products will be returned or replaced to the extent the Company is liable therefor after verification.

(III) Whether the revenue confirmation method applicable to the part of sales revenue realized through AXT and the implementation of accounting policies are consistent;

According to the Accounting Standards for Business Enterprises No. 14 - Revenue, since AXT can control the products after purchasing the products from the Company and before transferring the products, it is judged that AXT is the main responsible person. Therefore, the Company loses its control over the products after selling the products to AXT, and confirms the revenue after the products are delivered.

The Company judges AXT as the main responsible person for the following reasons:

1. AXT has the pricing power when selling the products purchased from the Company, and can independently determine the price of products sold to downstream customers;

2. AXT's payment of goods to the Company is not related to AXT's collection of payment from downstream customers, that is, AXT pays goods to the Company on a regular basis and does not default on the Company's payment because its downstream customers default on the payment;

8-1-1-218

3. AXT is primarily responsible for selling to downstream customers. AXT promises to provide quality assurance services to downstream customers and bear the responsibility of quality assurance. The Company does not bear any responsibility of quality assurance to downstream customers;

4. The trade between the Company and AXT is made on terms of FOB, under which AXT needs to bear the risk of damage and loss of inventory before product transfer. During sea transportation, when the products cross the ship's rail or during air transportation, when the products are delivered to the custody of the air carrier or agent, the Company can confirm the sales revenue. When the Company completes the product delivery obligation, the performance obligation of the sales contract will be completed.

Assuming that the Company recognizes revenue from sales of products to AXT when AXT sells the same, the comparison between its such revenue and the current revenue during the reporting period is as follows:

As can be seen from the above table, the discrepancy between the revenue of the Company from sales of products to AXT on the assumption that it is recognized when AXT sells the same and its current one is small, which was mainly caused by the time difference.

During the reporting period, since the trading mode of sales orders signed between the Company and AXT has not changed significantly, the Company has not significantly changed the sales revenue confirmation method of AXT, and the implementation of accounting policies is consistent.

(IV) The return and exchange of products during and after the reporting period and the main reasons;

8-1-1-219

During and after the reporting period (as of the end of February 2022), the amount of goods returned and exchanged by the Issuer was RMB1.8611 million, RMB2.5389 million, RMB4.5334 million and RMB828,400 (unaudited) respectively, accounting for 0.40%, 0.51%, 0.54% and 0.50% (unaudited) of the main business revenue of the current period, respectively, with small proportion, mainly due to the surface defects of the Company's semiconductor substrate materials after customers' epitaxial production, in response to which, the Company will have the following after-sales processing: when the sold products can be processed and utilized, they will be resent to the customer after the repair meets the relevant technical standards; When the product is damaged and cannot be recycled, the customer will be compensated and sent a new product.

(V) Details of the provision of processing materials supplied by customers to AXT, and the revenue confirmation method applicable to the relevant revenue.

At the beginning of its establishment, the Company mainly focused on overseas customers. AXT, as the entity making sales and purchasing raw materials overseas, provided the Company with main raw materials, etc., took delivery of semiconductor substrate products from the Company after processing by the Company, and sold them to overseas customers. AXT provides or designates main raw materials and a certain amount of auxiliary materials. The Issuer provides processing business against consideration, covering processing fees and other costs (self-purchased main and auxiliary materials, labor, depreciation, amortization, etc.). Under the processing mode with supplied materials, the Issuer does not record the materials provided by AXT, and confirms it as processing service revenue.

With the rapid development of the semiconductor industry in China, downstream customers have grown rapidly, and the production level of domestic suppliers has gradually improved. Since August 2018, the business between AXT and the Issuer has changed from entrusted processing to general trade.

In 2018, the main raw materials and auxiliary materials from AXT for processing received by the Company, the production costs invested by the Company and the corresponding income are detailed as below:

For the processing and sales business with materials supplied by AXT, the relevant processing revenue is recognized using the net method when the Issuer has completed the customs declaration of the goods according to the contract, the relevant economic benefits are likely to flow in, and the main risks and rewards of property in the goods have been transferred.

The Issuer recognizes the revenue from professing with supplied materials by the net amount method. In 2018, the Company still applied the Accounting Standards for Business Enterprises No. 14 - Revenue (CK [2006] No. 3), but since the standards have no express provisions on how to judge a principal liable person and an agent, the Issuer made the judgment the same with reference to the provisions on applicable revenue recognition of the Accounting Standards for Business Enterprises No. 14 - Revenue (CK [2017] No. 22).

Pursuant to Article 34 of the Accounting Standards for Business Enterprises No. 14 - Revenue (CK [2017] No. 22), an enterprise shall judge whether it acts as the principal liable person or an agent when conducting transactions based on the fact whether it has the right to control the goods before transferring them to the customer. If the enterprise is able to control the goods before transferring them to the customer, the enterprise acts as the principal liable person and shall recognize revenue according to the total consideration received or receivable; otherwise, the enterprise acts as an agent and shall recognize revenue according to the amount of expected commission or handling charge to which the enterprise is entitled, and such an amount shall be

8-1-1-221

determined according to the total consideration received or receivable deducted by the price to be paid to other parties, or according to a specified commission amount or proportion, among others.

In light of the contractual terms, the basis for the Issuer to determine the use of net amount method for recognizing revenue from processing with supplied materials is as follows:

1. Whether the enterprise is primarily responsible for transferring goods to the customer: the Issuer does not assume the primary responsibility for transferring goods to AXT as raw materials are mainly supplied by AXT or purchased from suppliers designated by AXT, and the entrusted processing technical standards and quality requirements are formulated by AXT;

2. Whether the enterprise bears inventory risks in relation to the goods before or after the transfer thereof: for the raw materials supplied by AXT, the ownership and control of their inventories remain with AXT, with the Issuer only bearing the risk of damage to and loss of such inventories caused by improper storage;

3. Whether the enterprise has the right to independently decide on the price of traded goods: the price of the products sold by the Issuer to AXT does not include the cost of corresponding raw materials, and the Company can only price the processing fees included in the final products and the materials purchased by itself, having no full right to decide on the sales price of the final products;

To sum up, the Issuer's processing with supplied materials is in essence a business whereby the main raw materials are supplied by AXT or purchased from suppliers designated by AXT, and the Issuer processes goods in accordance with AXT's quality standards against the charge of processing fees. The Issuer only bears the risk of damage to and loss of inventories caused by improper storage without full right to decide on the sales price of the final products. The Issuer judges that the Company has no control right over the goods before transferring them and thus acts as an agent in such business with reference to the Accounting Standards for Business Enterprises No. 14 - Revenue (CK [2017] No. 22). Accordingly, the net method is used for the recognization of relevant revenue.

Note: Since the Company's sales of semiconductor substrate materials overseas have been carried out through AXT-Tongmei since March 2021, the E-port data and the Issuer's overseas sales revenue in 2021 are only based on the overseas sales directly carried out by the Issuer's domestic entities in China.

It can be seen from the above table that in 2019 and 2020, the Issuer's E-port data was basically consistent with the export revenue data; the relatively large discrepancy in 2021 arose mainly from the new consignment customers of the Company due to the business handover between AXT and AXT-Tongmei in March 2021. For details, please refer to "X.(II).6.(5) Collection of price for goods and adjustments to sales during the period for which ATX's business was transferred to the Company's subsidiary in the US" in Section VII of the Prospectus. After excluding the above factors, there was no discrepancy between the Company's E-port data and export revenue data in 2021.

In 2020, the unit price of 3-inch InP substrate decreased by 16.33% on a year-on-year basis, mainly because that on the one hand, the purchase price of indium phosphide polycrystalline reduced by 8.58%; on the other hand, the sales volume of Customer A, the biggest customer of 3-inch products at home, decreased largely in 2020 due to its high standard of product performance and parameter and high price of its products, all of which make the unit price of 3-inch indium InP substrate reduced. The sales volume of the products in 2020 are mainly caused by the reduced orders of Customer A.

In 2020, the unit price of InP substrate in other specifications increased by 27.49% from RMB1.373 million in 2019 to RMB8.9586 million since: Visual Photonics Epitaxy purchased 4-inch InP substrate in a larger quantity and enhanced its products performance and quality which made the unit price raised quickly; the price also increased with the rise of the overall market demand from overseas customers and the improvement of product quality requirements; in 2020, the sales volume of indium phosphide in other specifications increased by 50.17% on a year-on-year basis driven by the rapid demand growth due to the fast development of 5G communication, big data, cloud computing and others.

In 2021, the unit price of InP substrate increased by 83.24% for the 3-inch one on a year-on-year basis, and increased by 66.65% for other specifications, mainly because: on the one hand, the Company, as the world's second largest InP supplier, appropriately

8-1-1-230

increased the sales price given the relatively tight product supply with the increase of global demand for downstream optical chips, optical module epilayer and devices; and on the other, since March 2021, the Company has directly dealt with end customers by selling products to overseas customers through AXT-Tongmei, also leading to the rise of the price to a certain extent. The sales volume of InP substrate in 3-inch and other specifications increased by 29.63% and 24.98% respectively due to the increased demand in the downstream market. The orders from our main customers increased to varying degrees.

In 2020, the unit price of 6-inch GaAs substrate of the Company increased by 19.61% on a year-on-year basis, and the products in other specifications increased by 13.30%, due to the increased purchase price (increased by 12.69%) of raw materials, Gallium. The unit price of the downstream products increases as the cost of raw materials raised. The sales volume of 6-inch GaAs substrate increased by 22.47%, mainly due to the increased demand of customers and the acceptance to the products of the Company, Osram, WIN SEMICONDUCTOR CORP., Epi Solution Technology Co., Ltd. and other customers improved their purchase volume of the products in main specifications; and the sales volume of the products in other specifications were stable.

In 2021, the unit price of 6-inch GaAs substrate of the Company reduced by 31.84% and other products in other specifications increased by 17.36%, mainly because that the 6-inch GaAs substrate is popular abroad while the 4-inch products are popular at home. According to Yole's statistics, the shipment volume of GaAs substrate in 2021 is expected to increase by 26.98% compared with that in 2020. Given the scaling up of the market and the steady expansion of its production capacity for GaAs substrate, the Company has further strengthened its preferential efforts for the international market; In addition, under the fierce international market competition, the Company adopted a more radical market strategy for its GaAs substrates which had a lower market ranking than those of Freiberger and Sumitomo in order to explore the international market thereof, resulting in an increase by 40.72% in the sales volume of its mainstream size products. In turn, on the domestic market, the price of products increased due to the increased price of Gallium, high demand of products and others.

Based on the specifications, the sales revenue of 4-inch germanium substrate accounts for a relatively high proportion. Among the products in other specifications, the sales revenue of 6-inch products are more than that of 2-inch and 3-inch. In respect of the germanium substrate, due to the difference of epitaxial process in difference

8-1-1-233

regions, most of the manufacturers abroad have their own method to process the epitaxial wafer in large size, so, among the products in other specifications, 6-inch products mostly sold overseas are most popular; and most of 4-inch products are sold domestically.

In recent years, due to the increased competition, Yunnan Lincang Xinyuan Germanium Industry Co., Ltd. and other manufacturers have laid out the production and sale of germanium substrate; meanwhile, the downstream customers have increased their orders year by year due to the rapidly increasing demand of solar photovoltaic cells, high-performance light emitting diodes and other device products in the aerospace field, all of which caused the Company to make concessions to the pricing; during the reporting period, the sales volume of 4-inch products increased fast while the unit price reduced to some degree.

For products of other specifications, the Company mainly sold them for export. Before March, 2021, the Company sold the germanium substrate overseas through AXT. In 2020, the unit price increased by 26.76% as the purchase volume of Mo Sangyo Co, Ltd. in Japan reduced from 44.73% in 2019 to 25.08% in 2020 and it always purchased the 2-inch product which has a low unit price. During the reporting period, the sales volume increased first and then reduced as the downstream customers changed their purchase volume based on the market. Among them, Osram, one of our main customers, had a large demand in 2020, but Mo Sangyo Co, Ltd. reduced its demand for such products year by year.

The unit price of single-crystal growth crucible was stable in 2019 and 2021, and relatively high in 2020 as Sumitomo purchased the highly customized single-crystal growth crucible mainly using LEC method with large size and high price. The sales volume of the single-crystal growth crucible was stable in 2019 and 2020, and increased by 38.18% on a year-on-year basis in 2021 as Yunnan Xinyao Semiconductor Materials Co., Ltd., Daqing Yitai Semiconductor Materials Co., Ltd. and Zhejiang Compound Semiconductor Co., Ltd. under Yunnan Lincang Xinyuan Germanium Industry Co., Ltd. raised their demand for the products as the development of their Companies.

Except for crystal growth crucibles, the overall incomes from other types of crucibles decreased slightly, mainly caused by the decline in sales due to the impact of downstream customer orders. The unit price of each such crucible was also different

As the table shows, during the reporting period, the increased gross profit margins of the Issuer were caused by the InP and GaAs substrates, high purity metal and compound products. The detailed situations are listed as follows:

(1) In 2020

The overall gross profit margin of the Company increased by 6.25% in 2020, mainly:

1) Due to the impact of the downstream customers' purchase policy, Customer A, the largest customer of 3-inch InP substrate materials, had its sales volume reduced to a large degree in 2020; due to its higher requirements on product performance and parameters, its product selling price and the gross profit margin is also relatively high. The decrease in sales has lowered the overall average unit price in 2020, which has caused the gross profit margin of InP substrate to drop slightly from 40.65% to 38.64%,

8-1-1-240

causing the gross profit to drop by 0.46%; meanwhile, due to the relatively high gross profit margin, InP substrate had a lower revenue growth rate than that of GaAs substrate products, resulting in a decline of its revenue proportion, and a decrease of its overall gross profit margin by 0.76%. In 2020, the Company's overall gross profit margin decreased by 1.20% as a result of the InP substrate material products.

2) On the one hand, affected by the rising market price of downstream raw material metal gallium, and the increase in the proportion of sales of large-scale products, the average sales unit price of GaAs substrate materials rose from RMB378.50/piece to RMB466.33/piece; and on the other, due to the improvement of personnel proficiency with completion of the relocation in Chaoyang, Liaoning and Baoding, Hebei, and the relatively low labor cost and fuel cost, the overall gross profit margin of GaAs substrate increased by 17.78%, driving an increase of the Company's overall gross profit margin by 7.04%; meanwhile, the average sales unit price, revenue share and gross profit margin of high purity metal and compound also increased with the increase in the market price of gallium, resulting in an overall gross profit margin increase of 1.04%.

(2) In 2021

The overall gross profit margin of the Company increased by 8.85% in 2021, mainly because:

1) On the one hand, the Company, as the world's second largest InP supplier, appropriately increased the sales price given the relatively tight product supply with the increase of global demand for downstream optical chips, optical module epilayer and devices; and on the other, since March 2021, the Company has directly dealt with end customers by selling products to overseas customers through AXT-Tongmei, also leading to the rise of the price to a certain extent, which made the average unit price of InP substrate increased to a large degree and the gross profit margin increased from 38.64% to 54.42%, driving the gross profit margin to be increased by 6.83%. Besides, as the gross profit margin of InP substrate increased, the revenue share of InP substrate increased significantly with the increasing of the gross profit margin due to the unit price, making the overall gross profit margin improve by 4.25%. Therefore, InP substrate products drove the overall gross profit margin increased by 9.42% in 2021.

8-1-1-241

2) First, with the operation of factories in Baoding and Chaoyang, the order quantity of GaAs substrate increased as well as its production efficiency and scale; second, the labor costs, gas power costs and other prices in Baoding and Chaoyang were relatively lower compared with Beijing, and the operating rate increased, further reducing the comprehensive cost; third, in terms of product structure, in 2021, the proportion of the Company's revenue from 3-inch GaAs substrate materials, which had a relatively high gross profit margin, increased by 6.31% year on year; additionally, while some GaAs production lines in Beijing Tongmei in 2020 being allocated the fixed costs of the Beijing plant, the GaAs substrates was no longer subject to such allocation in 2021, further increasing the gross profit margin of GaAs substrate to 25.59%; in 2021, GaAs substrate products boosted the Company's overall gross profit margin by 4.14%.

Besides, in terms of products, the fluctuation of the gross profit margin and the revenue share of germanium substrate and PBN crucible also affected the overall gross profit margin of the Company; in terms of indicators, the fluctuation of exchange rate impacted the gross profit margin as well.

2 Comparison of the gross profit margin from the main businesses between the Company and equivalents in the same industry

The comparison of the gross profit margin from the main businesses between the Company and equivalents in the same industry during the reporting period are as below:

Note: The data on SICC and NSIG are sourced from their annual reports and prospectuses.

In 2020, the gross profit margin of semiconductor substrate increased from 11.80% to 19.05%, consistent with the gross profit margin of SICC. The gross profit margin of NSIG decreased slightly in 2020, mainly because: the semiconductor silicon wafers in the size of 200mm or less are maturing products and NSIG has formed a scale effect;

8-1-1-242

and at the same time, its fixed cost has increased significantly given the increase in the production capacity for 300mm semiconductor silicon substrates. In 2021, the gross profit margin of the Company's semiconductor substrate products was close to that of SICC's primary business.

(IV) The reason for the continuously decreased gross profit margin of gallium arsenide and germanium substrate during the reporting period.

1. GaAs substrate

During the reporting period, the gross profit margin of GaAs substrate were -9.13%, 8.65%, and 25.59% respectively, showing a year-on-year growth.

The gross profit margin of GaAs substrate in 2019 was relatively low. As for the reason, the production line of GaAs substrate was relocated from Beijing to Chaoyang, Liaoning and Baoding, Hebei and recruited new production staffs, during when, the raw materials wasted a lot and the yield of GaAs substrate was low due to the commissioning of the production line and the technically rusty employees. All such factors raised the business cost of the Company. In 2020, the production efficiency was enhanced with the improved working proficiency of employees and the optimized machines and equipment. Moreover, with the increased price of gallium, the price of products also increased. Meanwhile, the increased sales volume of large size products drove the rising of the unit price of GaAs substrate. As a result, the gross profit margin of GaAs substrate improved in 2020.

In 2021, the gross profit margin of GaAs substrate increased a lot. As for the reason, first, the production efficiency and scale effect further improved as the orders to the factories in Baoding, Hebei and Chaoyang, Liaoning increased; second, the labor costs, gas power costs and other prices in Baoding and Chaoyang were relatively lower compared with Beijing, and the operating rate increased, further reducing the comprehensive cost; third, in terms of product structure, in 2021, the proportion of the Company's revenue from 3-inch GaAs substrate materials, which had a relatively high gross profit margin, increased by 6.31% year on year; additionally, while some GaAs production lines in Beijing Tongmei in 2020 being allocated the fixed costs of the Beijing plant, the GaAs substrates was no longer subject to such allocation in 2021,

8-1-1-243

which is also an associated reason.

2. Germanium substrate

During the reporting period, the gross profit margin of germanium substrate was 20.60%, 18.44% and 0.21% respectively. The continuous decline in gross profit margin was mainly affected by the continuous decline in the average unit price. During the reporting period, the average unit price of germanium substrate was RMB351.05/piece, RMB336.81/piece and RMB287.74/piece respectively. Thereinto, the gross profit margin of germanium substrate decreased by 2.16% in 2020 since the unit price decreased by 4.06%. In recent years, as Yunnan Lincang Xinyuan Germanium Industry Co., Ltd. and other manufacturers have laid out the production and sale of germanium substrate, the domestic competition are intensified; meanwhile, the downstream customers have increased their orders year by year due to the rapidly rising demand of solar photovoltaic cells, high-performance light emitting diodes and other device products in the aerospace field, all of which caused the Company to make concessions to the pricing to some degree.

The gross profit margin in 2021 is 18.23% lower than that in 2020 as the average unit price decreased by 14.57%. Due to the difference of epitaxial process in difference regions, most of the manufacturers abroad have their own method to process the large-size epitaxial wafer. Therefore, products with other specifications are mainly 6-inch products and mainly exported; while most of 4-inch products were sold domestically. In 2021, due to the impact of the domestic and overseas market, the sales volume of 4-inch products continuously increased by 40.84%, while that of 6-inch products decreased by 54.42%; at the same time, affected by the fierce competition pattern in China, the unit price of mainstream 4-inch products, which had a revenue accounting for about 80% and a price being significantly different from that of 6-inch products, continued to decline by 6.00%, resulting in a significant decrease in the comprehensive average unit price.

In addition, according to the 2021 annual report disclosed by Yunnan Germanium Industry, in 2021, its sales unit price of germanium substrate products decreased by 27.27% to RMB283.70/piece from RMB390.06/piece in 2020, which is consistent with

8-1-1-244

the downward trend of the Company's sales price.

The Company's inventories are mainly gallium arsenide, indium phosphide, germanium substrates and other inventory commodities, as well as unprocessed and uncut crystal bars and various raw materials. At the end of each period of the reporting period, the book balance of the Company's inventories was respectively RMB269,292,100, RMB299,198,000 and RMB401,034,500 respectively; during the reporting period, the Company realized revenues of RMB462,226,800, RMB583,170,400 and RMB857,345,200 respectively. On the whole, the inventory balance increased with the revenues, with a consistent fluctuation.

In terms of inventory composition, at the end of each period of the reporting period, the proportion of various types of inventories has changed. The specific reasons are as follows:

1. Raw materials

At the end of each period of the reporting period, the Company's book balance of raw materials was RMB42,410,700, RMB101,015,000 and RMB66,556,100 respectively, accounting for 15.76%, 33.76% and 16.60% respectively.

8-1-1-246

At the end of 2019 and at the end of 2021, the proportion of raw materials was relatively stable, while that at the end of 2020 was higher. The main reasons are as follows: (1) The Company's production base in Chaoyang was gradually completed in 2020, the production line has been launched for commissioning, and the Company has increased the procurement of raw materials as needed for the new capacity. (2) With the increasing market demand for various products, the Company obtained more orders at the end of 2020. (3) With the rising price of metal gallium, the Company expects a continued upward trend. Thus, in the second half of 2020, the Company increased the purchase of metal gallium appropriately. (4) As the germanium ingot market was affected by the short supply of upstream raw materials, the market supply of germanium was in a short state, and the Company increased the purchase of germanium ingots.

2. Changes in semi-finished products

At the end of each period of the reporting period, the balance of semi-finished products of the Company was RMB110,934,000, RMB87,469,500 and RMB120,528,100 respectively, accounting for 41.19%, 29.23% and 30.05% respectively.

The proportion of semi-finished products at the end of 2020 and 2021 was relatively stable. At the end of 2019, the proportion of semi-finished products was relatively high, mainly because of the relocation of gallium arsenide crystal production, gallium arsenide chip production and high-purity material production from Beijing Tongmei and Nanjing Jinmei to Chaoyang Tongmei, Baoding Tongmei and Chaoyang Jinmei; meanwhile, in the second half of 2018, Beijing Boyu was notified that its leased plant would be expropriated, so that it would relocate its production equipment successively to Chaoyang Boyu and other plants in 2019. Affected by the expected relocation, the Company reserved a large quantity of semi-finished products at the end of 2018. However, due to the inadequate operation rate due to the relocation in 2019, some semi-finished products were not claimed in time.

3. Changes in work-in-process

8-1-1-247

At the end of each period of the reporting period, the Company's balance of work-in-process was RMB76,895,800, RMB74,353,300, and RMB127,630,100 respectively, accounting for 28.55%, 24.85% and 31.83% respectively, and the proportions fluctuated.

In terms of balance, at the end of 2020, the Company's work-in-process remained relatively stable, while the proportion decreased slightly compared with that at the end of 2019, mainly due to the reserve of more raw materials pending use at the end of the year.

At the end of 2021, the proportion increased significantly due to the following reasons: (1) after the Company completed the relocation, the production line in Chaoyang was completed in 2020 and 2021, which continued to release capacity; (2) affected by the rapid increase in the demand of the downstream application market, in 2021, the sales of various major products of the Company all showed a certain increase, further improving the Company's operating rate. Due to all of the foregoing reasons, the amount and proportion of work-in-process increased rapidly at the end of 2021.

4. Changes in goods in stock

At the end of each period of the reporting period, the balance of Company's goods in stock was RMB39,051,500, RMB35,580,200, and RMB66,214,900 respectively, accounting for 14.50%, 11.89%, and 16.51% respectively.

At the end of 2020, the balance and proportion of the Company's goods in stock decreased slightly, mainly because of: (1) The market demand for high-purity gallium increased significantly in 2020, and the sales revenues in 2020 increased by 198.70% compared with that in 2019, resulting in a significant increase in shipment. (2) The Company reserved a large quantity of raw materials at the end of 2020, resulting in a decline in the proportion of goods in stock.

At the end of 2021, the balance and proportion of the Company's goods in stock increased significantly, mainly because of: Affected by the rapid increase in the demand of the downstream application market, the sales of various main products of the

8-1-1-248

Company in 2021 showed a certain increase. Meanwhile, the number of the Company's orders on hand increased rapidly; as a result, for timely delivery to downstream customers, the Company accelerated the production schedule on the basis of an increased production capacity.

5. Changes in goods upon delivery

At the end of each period of the reporting period, the ending balance of goods upon delivery by the Company was 0, RMB780,000 and RMB20,105,200 respectively, accounting for 0, 0.26% and 5.01% respectively.

At the end of 2021, the quantity of goods upon delivery increased rapidly. The reason was that after the Company completed the switch in March 2021, some new consignment customers were newly added, resulting in an increase in the balance of overseas consignment inventory.

(II)At the end of each period of the reporting period, the matching between the Company's inventory balance and the orders on hand, as well as the sales and carry-over after the inventory balance period during the reporting period:

At the end of each period of the reporting period, the inventory coverage for orders on hand of the Company was 72.70%, 88.85% and 97.39% respectively, showing a rapid increase on a year-on-year basis, which was close to 100% at the end of the reporting period. The finished products coverage for orders on hand was 501.33%, 731.11% and 452.44% respectively, representing a full coverage of finished products of the Company. In recent years, due to the rapid development of downstream sectors and the continuous expansion of product application fields, the demand for various products of the Company has increased, and the orders on hand and the ending balance of inventory have also increased rapidly. Generally speaking, the coverage of the amount of orders on hand to the inventory balance is relatively high, and the ending balance of inventory basically matches the orders on hand.

2.Post-period sales and carry-over of inventory balance during the reporting period

As of February 28, 2022, the Issuer's subsequent carry-over of inventory at the end of each period of the reporting period was as follows:

(III)Method and basis for determining the net realizable value of inventory, the provision for declining prices of inventory of different storage ages, and whether the provision for declining prices of inventory is adequate.

8-1-1-250

1.Method and basis for determining the net realizable value of inventory

The Issuer measures the carrying amount of inventories at the cost or the net realizable value on the balance sheet date, whichever is lower. If the cost of inventory is higher than its net realizable value, the provision for inventory depreciation is made. For inventories held for the performance of sales contracts, the net realizable value of inventories is calculated based on the contract prices, and for other general products, it is calculated based on the prices of the same or similar products sold recently. Meanwhile, based on the principle of prudence, for auxiliary materials of more than 1 year, the Company makes a full provision for inventory depreciation; for separately identified deteriorated, damaged or unusable inventories, the provision is separately made.

For finished products directly used for sale, the net realizable value is determined by the estimated selling price of the inventory less the estimated selling expenses and relevant taxes; for materials held for production, etc., where the net realizable value of the finished products produced from such materials is higher than the cost, the materials should still be measured at the cost; if the decline in the price of the materials indicates that the net realizable value of the finished products is lower than the cost, the materials should be measured at the net realizable value.

2.Provision for declining prices of inventory of different storage ages, and whether the provision for declining prices of inventory is adequate

The provision for declining prices of inventory of different storage ages at the end of each period of the reporting period is as follows:

At the end of each reporting period, the Issuer's inventories mainly had an age of within one year, accounting for a relatively high proportion of 90.61%, 93.74% and 93.79% respectively. The provisions for decline in value of inventories were made focusing on those aged over one year, of which, the Company has made full provisions for the auxiliary materials aged over 1 year for the sake of prudence, and also made provisions for some semi-finished products and finished products due to changes in customer demand and other reasons.

The Issuer's products are customer-oriented, with customized products accounting for a high proportion. At the end of each period of the reporting period, the Issuer had a relatively adequate inventory coverage of orders on hand; the inventory balance within one year accounted for a relatively high proportion; and the subsequent carry-over of inventory was in a good condition. Besides, a comparison of the ratio of provision for decline in value of inventory between the Company and comparable listed companies in the same industry is as follows:

Note: The data on SICC and NSIG are sourced from their annual reports and prospectuses.

The proportion of the Company's provision for decline in value of inventory is generally higher than the average level of comparable companies in the same industry, mainly due to the relatively low proportion of SICC. At the end of 2020, the proportion

8-1-1-252

of the Company's provision for decline in value of inventory was lower than that of NSIG, mainly because the production of epilayers in 300mm wafers was still in the ramp-up stage with continuous product certification, the process and quality needed to be improved, and the production cost was higher than their market price.

To sum up, the Issuer's provision for inventory depreciation is adequate.

Within the reporting period, the Issuer's balance of accounts receivable increased year by year with the increase of its sales revenue, accounting for 35.63%, 35.26% and 34.83% of the current revenue respectively, representing a slight decline year by year. The turnover days of accounts receivable were 146.17days, 115.89 days and 107.36 days respectively, which are gradually shortened, showing that accounts receivable is well handled.

To sum up, the increase of accounts receivable balance is mainly due to increase of the Issuer's operating income, and the ending balance of accounts receivable matches its sales scale and therefore it is reasonable.

According to the characteristics of the industry and combined with its own production and operation conditions, the Issuer has formulated a more prudent credit policy for different types of customers: for new customers, advance payment is adopted; for regular customers, the credit policies are developed by taking into full account the basic situation, business scale, cooperation time, amount of orders and contracts, financial status, payment and payment, etc. of the customer. The credit period is normally 1-3 months. In addition, the Issuer conducted business negotiations with customers to slightly adjust the credit policies taking into account the product production, technical requirements, and cooperation relationship with customers. Within the reporting period, except for Osram and Landmark Optoelectronics, the Issuer's credit policies for major customers remain unchanged.

After penetrating into AXT, Osram and Landmark Optoelectronics were among Issuer's top five customers within the reporting period, and they have been working together for many years. Within the cooperation period, they have been maintaining good relations. As well-known enterprises in the industry, Osram and Landmark Optoelectronics have sound credit history, with timely payments since the very beginning of their cooperation. In March 2021, the Issuer exchanged business with AXT, aiming to enhance customer cooperation and give the customer certain buffer time in handling matters such as contract management and fund audit, so as to ensure that the business exchange could be completed as soon as possible. Besides, in order to maintain

8-1-1-259

the Issuer's sustained and sound development, it extended the credit period for the above two customers appropriately.

To sum up, within the reporting period, the credit policy of its sales business was relatively stable, and there was no loosening of credit policies or extending the credit period to stimulate sales.

In the semiconductor sector, it is common to adopt bills for settlement. At the end of each period of the reporting period, its customers for bills receivable and accounts receivable financing mainly include leading manufacturers of extended industry chain in China. In 2021, due to the tight supply of high-purity gallium and gallium oxide markets, its related income increased substantially, and Argosun Electronic New Materials Co., Ltd. and Jiangsu Bree Optronics Co., Ltd. were also among its top five customers of the bills receivable and accounts receivable financing.

2. Financing endorsement, discount and derecognition of bills receivable and accounts receivable financing, and whether the relevant accounting treatments comply with the provisions of the accounting standards for business enterprises

During the reporting period, no discount was found for bills receivable and accounts receivable financing on the part of the Issuer. At the end of each reporting period, the Issuer's undue bills with endorsement had a balance of RMB40.0537 million, RMB70.7175 million and RMB100.1745 million, of which the bills derecognized accounted for 52.64%, 72.24% and 82.70%, respectively.

According to the principle of prudence, the Issuer categorized the acceptance banks issuing the received bank acceptance bills as six major commercial banks with higher credit ratings and nine listed joint-stock commercial banks, other commercial banks and financial companies with average credit ratings. The above six major commercial banks include Bank of China, Agricultural Bank of China, China Construction Bank, Industrial and Commercial Bank of China, Postal Savings Bank of China and Bank of Communications, and the nine listed joint-stock commercial banks are China Merchants Bank, Shanghai Pudong Development Bank, China CITIC Bank, China Everbright Bank, Huaxia Bank, China Minsheng Bank, Ping An Bank, Industrial Bank and Zheshang Bank. For acceptance bills from accepting banks with high credit ratings, the derecognition time is the endorsement transfer date, discount date or maturity date. While for acceptance bills from accepting banks with relatively low credit ratings and commercial acceptance bills accepted by enterprises, the derecognition time is the maturity date of the acceptance bills. Within the reporting period, the Issuer had no bill discount or bill default.

To sum up, within the reporting period, the derecognition of the endorsement of its bills receivable complies with relevant provisions of Accounting Standard for Business Enterprises No. 23 - Transfer of Financial Assets, Accounting Standard for Business Enterprises No. 23 - Transfer of Financial Assets (Application Guide), Case Analysis of Listed Companies Implementing Accounting Standard for Business Enterprises (2020) and so forth.

2. Whether no provision for bad debts for AXT and Customer B is in compliance and the provision for bad debts is sufficient in 2018, and differences compared with comparable companies in the same industry and relevant reasons

(1) Whether bad-debt provisions for AXT and Customer B is compliant and sufficient in 2018

On December 31, 2018, the Issuer still applied the Accounting Standard for

8-1-1-265

Business Enterprises No. 22 - Recognition and Measurement of Financial Instruments (Cai Kuai [2006] No. 3) (hereinafter referred to as the "Former Standards for Financial Instruments"). According to Article 40 of the above standards, enterprises shall check the carrying amount of financial assets other than those measured at fair value and its balance is included in current profits and losses on the balance sheet date, and if there is any evidence showing that the financial assets are impaired, provision for impairment shall be done.

After comprehensively and cautiously evaluating the customer's market position, shareholder's background, credit status, business cooperation history, payment situation, business environment and other factors, the Issuer believed that AXT and Customer B had no signs of impairment, and no provision for bad debts should be made. The details are as follows:

1) AXT is a NASDAQ listed company with sound credit. As both the customer and supplier of the Issuer, it has been a partner for many years. As of December 31, 2018, the amount payable to AXT by the Issuer is far greater than the amount of receivables from AXT, and both parties have communicated about the payment plan for such gap, which will be fully recovered after due date.

2) Customer B, a partner of the Company for over 20 years, boasts a favorable business performance, with a sales scale of RMB100 billion, a registered capital of RMB20 billion and a high credit rating, awarded a credit rating of AAA by China Lianhe Credit Rating Co., Ltd., all receivables from whom as of December 31 have been fully recovered after the due date.

From January 1, 2019, the Issuer started to apply the Accounting Standard for Business Enterprises No. 22 - Recognition and Measurement of Financial Instruments (Cai Kuai [2017] No. 7) (hereinafter referred to as the "New Standards of Financial Instruments"). Taking into consideration the expected credit risk, for receivables, the Issuer first separates the receivables with significant amounts for impairment tests. The accounts receivable that have not been impaired after tests (including accounts receivable with significant and insignificant amounts), are included in the accounts receivable portfolio with similar credit risk characteristics for further impairment tests.

8-1-1-266

According to the Certain Questions and Answers on IPO Business issued by China Securities Regulatory Commission, it is necessary to consider the expected credit risk instead of excluding the provision for bad debts on the grounds that the defaulting party is a related party customer, a high-quality customer or a customer regarding government projects. The Issuer categorizes the customers with accounts receivable as low-risk, medium-risk and high-risk customers, and therefore classifies it as a low-risk customer based on the above analysis of various dimensions of AXT and Customer B. Customers with a history of disputes or potential disputes or signs of bankruptcy are classified as high-risk customers, while other customers are classified as medium-risk customers. Depending on different risk categories, the expected default rate was taken into account, and the expected credit loss is accrued. As a result, the amounts due from AXT and Customer B have been accrued for expected credit losses accordingly since January 1, 2019.

To sum up, no provision for bad debts for AXT and Customer B at the end of 2018 was in line with the Former Standards for Financial Instruments. The receivables from AXT and Customer B have been recovered at the end of 2018. Since January 1, 2019, the Issuer has accrued impairment for the above customers according to the new standards for financial instruments, with sufficient provision for bad debts.

(2) Differences compared with comparable companies in the same industry

At the end of each period of the reporting period, the proportions of provision for bad debts of the Issuer and comparable companies in the same industry based on the combination of credit risk characteristics in the expected credit loss model are as follows:

Comparable companies in the same industry

At the end of 2021

Issuer

0.43%

0.72%

8-1-1-267

Note: The data on SICC and NSIG are sourced from their annual reports and prospectuses.

The Issuer's overall expected credit loss rate is consistent with the historical bad debt loss rate, and meanwhile it is close to that of NSIG and lower than that of SICC. The Issuer is more related to NSIG in terms of customer base and concentration. After excluding AXT, the Issuer's revenue from the top five customers of NSIG accounts for less than 30% of the total, with a certain proportion of overseas customers. However, the Issuer's revenue from the top five customers of SICC accounts for more than 80% of the total, mainly including Chinese customers, with some jeweler customers.

According to the above standard, the Issuer categorizes its customers as low-risk customers, medium-risk customers and high-risk customers. Appraisers adopt the credit rating to calculate ECL for low-risk customers, and the default rate of AAA bond rating of Brilliance Ratings as the historical default rate. The migration rate model is used to calculate ECL for medium-risk customers. The migration rate model is constructed according to the average migration of accounts receivable in the past three fiscal years so as to get the historical default rate. Then, calculate the expected default rate = historical default rate × prospective adjustments × discount coefficient.

To sum up, the Issuer has conducted provision for bad debts for accounts receivable according to its own actual condition. Its overall expected credit loss rate is close to that of NSIG and lower than that of SICC, which is mainly due to different customer structure, end-user market environment, customer distribution and so forth, and therefore it is reasonable.

II. Intermediaries' verification procedure

(I) Verification procedure

In response to the above matters, the Sponsor and the Reporting Accountant have performed the following verification procedures:

1. Taking into account the revenue, analyze the reasons and rationality of the rapid growth of accounts receivable balance, bills receivable and the receivables financing at the end of each period of the reporting period; Acquire the sales contracts signed by the Issuer and major customers, check the credit policies agreed in the contracts, and

8-1-1-268

analyze whether there are any changes in the credit policies for major customers within the reporting period;

2. Refer to the Law of the People's Republic of China on Negotiable Instruments, Accounting Standard for Business Enterprises No. 23 - Transfer of Financial Assets, Accounting Standard for Business Enterprises No. 23 - Transfer of Financial Assets (Application Guide), Case Analysis of Listed Companies Implementing Accounting Standard for Business Enterprises (2020) and other documents, and check whether the bills receivable that have been derecognized at the end of each period of the reporting period meet the derecognition requirements of Accounting Standard for Business Enterprises;

3. Obtain the details of the memorandum book of bills receivable within the reporting period, check the information such as the drawer, the previous signer, and the term and type of the bill, count the bills receivable received and endorsed within the reporting period and the major customers of the previous signer, and check the endorsement records and accounting treatment;

4. Conduct sampling inspection of large-amount guarantee deposits and other items in other receivables, check the reasons for their formation, check relevant guarantee contracts, deposit payment vouchers and other related documents, and recheck the rationality of the amount;

5. Obtain the aging schedule of the Issuer's accounts receivable within the reporting period and the schedule of payment after due date, and analyze the risk of recovering accounts receivable and whether the provision for bad debts is sufficient. Acquire the details of the Issuer's single provision for bad debts within the reporting period, and analyze the reasons and rationality. Check the policy of provision for bad debts of accounts receivable of comparable companies in the same industry, and compare and analyze whether there is significant difference between the policy of provision for bad debts of accounts receivable of the Issuer and that of comparable companies in the same industry;

6. Refer to the Accounting Standard for Business Enterprises No. 22 - Recognition and Measurement of Financial Instruments (Cai Kuai [2006] No. 3) and

8-1-1-269

the Accounting Standard for Business Enterprises No. 22 - Recognition and Measurement of Financial Instruments (Cai Kuai [2017] No. 7;

7. Interview the Issuer's finance chief, understand and evaluate the design effectiveness of its internal control on the recognition of accounts receivable, and test the operational effectiveness of key controls;

8. Confirm the balance of accounts receivable of the Issuer at the end of each period of the reporting period by letter. Spot check related sales contracts, invoices, payment receipts and other supporting documents for inspection;

9. Review the rationality of the Issuer's expected credit loss model with the support of the internal valuation experts of the Reporting Accountant, make recalculation based on the model and compare with the results of the Issuer;

(II) Verification opinions

Upon verification, the Sponsor and the Reporting Accountant believe that:

1. The increase of accounts receivable balance is mainly due to the increase of revenue. The ending balance of accounts receivable matches the Issuer's sales scale and therefore it is reasonable. Based on the business exchange between AXT and the Issuer, by working more closely with the customer, the Issuer gave the customer certain buffer time in handling matters such as contract management and fund audit, so as to complete the business exchange as soon as possible. On the other hand, in order to maintain the sustained and sound business growth between the Issuer and its customer, the Issuer appropriately extended the credit period for Osram and Landmark Optoelectronics. Within the reporting period, the Issuer's credit policy for major customers remained unchanged, and the Issuer did not loosen its credit policy to stimulate sales;

2. Within the reporting period, the customer has no financing discount of bills

8-1-1-270

receivable and accounts receivable. Relevant accounting treatments such as endorsement and derecognition of bills receivable and financing of accounts receivable comply with the provisions of Accounting Standard for Business Enterprises;

3. During the reporting period, the Company was not subject to conversion of bills receivable into accounts receivable due to any dishonoring of the former at maturity;

4. The guarantee deposits and other amounts of other receivables match related items and therefore it is reasonable;

5. The Issuer's bad-debt provision policy is in line with its own business characteristics and the historical receipts from customers. During the reporting period, accounts receivable were collected in a timely manner with sufficient bad-debt provisions having been made.

2. Valuation basis and principles for the fixed assets acquired through reorganization

In accordance with Accounting Standard for Business Enterprises No. 20 - Business Combinations (2006), with respect to the business combinations involving entities under common control, the assets and liabilities that are obtained by the acquirer in a business combination shall be measured at their carrying amounts determined by the acquiree at the combination date. The difference between the carrying amount of the net assets obtained and the carrying amount of the consideration paid for the combination (or the aggregate face value of shares issued as consideration) shall be adjusted against capital surplus. If the capital surplus is not sufficient to absorb the difference, any excess shall be adjusted against retained earnings.

The reorganization in December 2020 is the business combination involving entities under common control; therefore, the fixed assets acquired by the Issuer through reorganization shall be measured at their carrying amounts at the reorganization date as recorded in the financial statements of the Company. The difference between the carrying amount of the net assets obtained by the Company of the restructured party and the carrying amount of the aggregate face value of shares issued as consideration shall be adjusted against share premium under capital surplus. If the capital surplus is not sufficient to absorb the difference, any excess shall be adjusted against retained earnings.

2. Appropriateness of the depreciation policy, the consistency of the depreciation policy in each subsidiary, and any difference from the comparable companies in the same industry

The Company and all the subsidiaries adopt the consistent depreciation policy. The Company has specified different depreciation periods for different kinds of machines and equipment based on the purposes, estimated useful lives and practical experience, among which, the service life of most of the machines and equipment is between 5 and 15 years; the protective shells made of iron with a value of RMB16,091,100 are primarily used as fixing support for the crystal growth furnaces to provide certain protection. Because of the solid and durable material and based on the Company's practical experience, the protective shells are expected to be used for a long time, therefore their amortization period is 20 years.

Comparison of depreciation period of machines and equipment between the

Company and the comparable companies in the same industry:

Compared with the comparable listed companies in the same industry, except that the protective shells made of iron have a 20-year depreciation period thanks to their longer useful life, there is no big difference in the depreciation period of the other machines and equipment between the Company and the comparable listed companies in the same industry.

(III) Matching performance between the scale of the production equipment and the changes in production capacity, output and production and operation size;

During the reporting period, the matching performance between the scale of the production equipment and the changes in production capacity, output and production and operation size is outlined as below:

From the above table, it can be seen that in each period of the reporting period, the

8-1-1-275

scale of the Company's production equipment basically matches its production capacity, output and operation scale. With the improvement and optimization of the process flow and the gradual enhancement of employee proficiency after the relocation in Chaoyang and Baoding to stabilize the production, the unit production capacity and output of equipment have increased.

(IV) Reasons for the fixed assets held under a finance lease, composition of such fixed assets and reasons for the changes, and whether the accounting treatment of these fixed assets is in compliance with the Accounting Standard for Business Enterprises.

1. Reasons for the fixed assets held under a finance lease, composition of such fixed assets and reasons for the changes

The Issuer signed the Nitrogen Supply Agreement with Air Liquide (Tianjin) Co., Ltd. in 2018. It is agreed that the Company rents the nitrogen generator and nitrogen supply system under a finance lease which is used to supply the nitrogen in the production process. Compared with the procurement of liquid nitrogen, it is more cost-efficient to produce the nitrogen on the site with necessary nitrogen generators when the monthly nitrogen consumption exceeds the economic balance point. Additionally, the transportation of liquid nitrogen might be affected by some uncertain factors such as the traffic and it is more reliable and safer to produce nitrogen on the site. If the Company purchases the nitrogen generators and nitrogen supply system directly, it is a big investment with high maintenance costs. Therefore, it is more advisable to lease the equipment.

At the end of each period of the reporting period, the original cost of the fixed assets under a finance lease remains RMB14,794,900 with no change at all. Besides the nitrogen generators and nitrogen supply system, there is no other assets held under a finance lease during the reporting period.

2. Whether the accounting treatment of these fixed assets is in compliance with the Accounting Standard for Business Enterprises

8-1-1-276

(1) Prior to January 1, 2021

According to the terms and conditions of the lease contract signed between the Company and Air Liquide (Tianjin) Co., Ltd. in 2018, the lease term of the nitrogen supply system is ten years, matching with the ten-year estimated useful life of the nitrogen supply system, which satisfies Article 6 of Accounting Standard for Business Enterprises No. 21 - Leases (Cai Kuai [2006] No. 3): If a lease meets one ore more of the following criteria, it should be classified as a finance lease: (iii) even if the ownership of the asset is not transferred, the lease term covers the major part of the useful life of the leased asset.

1) Initial measurement

For the above fixed assets, the Company entered them in the item of "fixed assets" as debits based on the present value of minimum lease payment, entered them in the item of "long-term accounts payable" as credits based on the minimum lease payment, entered them in the item of "bank deposit" as credits based on the direct expenses initially incurred, and entered them in the item of "unrecognized financing expenses" as debits based on the difference, at the commencement date of the lease.

2) Subsequent measurement

The rents to be paid as scheduled were entered by the Company in the item of "long-term accounts payable" as debits and entered in the item of "bank deposit" as credits; the unrecognized finance charges distributed under the effective interest rate method shall be entered in the item of "financial expenses" as debits and entered in the item of "unrecognized finance charges" as credits; the depreciation to be calculated as scheduled shall be entered in the item of "manufacturing expenses" as debits and entered in the item of "accumulated depreciation" as credits.

In conclusion, the accounting treatment in 2019 and 2020 complies with the provisions of Accounting Standard for Business Enterprises No. 21 - Leases.

(2) After January 1, 2021

8-1-1-277

The new lease rules come in force on January 1, 2021. According to the Article 14 of Accounting Standard for Business Enterprises No. 21 - Leases (Cai Kuai [2018] No. 35): At the commencement date of the lease, the lessee shall recognize the right-of-use assets and lease liabilities except for the short-term lease and the lease of low-value assets of which the treatment is simplified according to Section 3, Chapter 3 of the Standard; Article 30: Short-term lease refers to the lease with a lease term no longer than 12 months on the commencement date of the lease; Article 31: Lease of low-value assets refers to a lease with a single leased asset having a relatively low value when it is brand new.

According to the terms and conditions in the lease contract signed between the Company and Air Liquide (Tianjin) Co., Ltd. in 2018, the lease term of the nitrogen supply system is ten years and the price is high. Therefore, it doesn't meet the criteria of short-term lease and lease of low-value assets. Instead, it shall be recognized as right-of-use assets and lease liabilities and considered as general lease in the subsequent measurement.

1) Initial measurement

The right to use the above nitrogen supply system during the lease term was recognized by the Company as right-of-use assets at the commencement date of the lease, including the amount of the lease liabilities in the initial measurement; estimated costs to be assumed by the Company for dismantling and removing the system, restoration of the venue where the system is located or restoring the system to the particular status specified in the lease contract. The present value of the unpaid lease payment shall be recognized as lease liabilities. When calculating the present value of the lease payment, the Company considers the incremental borrowing rate as discount rate as the interest rate implicit in lease is uncertain.

2) Subsequent measurement

Right-of-use assets are depreciated using the straight-line method in the subsequent measurement.

8-1-1-278

The lease payment made as scheduled is entered in the item of "long-term accounts payable" as debits and in the item of "bank deposit" as credits. The interest expenses of the lease liabilities during the lease term are calculated according to the incremental borrowing rate and recognized as profit or loss in the current period.

In conclusion, the above-mentioned accounting treatment complies with the provisions of Accounting Standard for Business Enterprises No. 21 - Leases.

8-1-1-281

progress etc.;

3. Pay a site visit and make a survey at the site of the construction in progress, and pay attention to the completion of construction in progress as well as any damage or idleness; examine whether the completed construction in progress has not been transferred to fixed assets;

4. Inquire and interview some of the suppliers, review the bank statement of the controlling shareholders, directors, supervisors, senior management, sale and procurement manager, staff playing a leading role in the finance, sale and procurement management to identify associated relationship and any payment made to or received from suppliers;

5. Obtain all bank statements of the Issuer for the reporting period; review the inflow and outflow with a large amount in the bank statement of the Issuer and verify the business background for such large-amount inflow and outflow to make sure it matches the expenditures of the construction in progress of the Issuer; pay attention to the transaction records between the Issuer and its affiliates and inquire the Issuer about the business background of such transaction and verify whether its affiliates make payment to the suppliers on behalf of the Issuer or not.

(II) Verification opinions

Upon verification, the Sponsor and the Reporting Accountant believe that the accounting of the construction in progress during the reporting period by the Company is complete, authentic and accurate and the payments made during this period are authentic and accurate.

14.3

According to the Prospectus, at the end of each year during the reporting period, the Issuer's carrying amount of intangible assets was RMB59,213,700, RMB58,410,000, RMB59,404,500 and RMB18,742,900, which included the land use right, patents and software. At the end of June 2021, the patents increased by RMB8,012,600, which were the intellectual property right licenses granted by

8-1-1-282

AXT to the Issuer and its controlled subsidiaries.

The Issuer is required to explain: (1) how the software is acquired and its specific purpose, and whether the transfer price of patents is fair and the basis for the transfer price; (2) how the amortization period of intangible assets is determined and whether the accounting treatment complies with the Accounting Standard for Business Enterprises.

It can be seen from the above table that the software owned by the Issuer is related to business operations such as daily office use.

2. Basis for the fair transfer price of patents

In November 2021, the Company entered into a Technology License Agreement with AXT, the controlling shareholder, pursuant to which, AXT shall license its patents and intellectual property rights, having an original cost of RMB8,012,600, to the Issuer

8-1-1-283

on a perpetual basis.

According to the appraisal report issued by Armanino LLP, a US appraisal institution appointed by the Issuer, Armanino LLP appraised the fair value of the patents with the income approach and in terms of royalty rates, selected 12 companies listed in the US stock market as comparable companies in the same industry for comparison taking January 1, 2021 as the base date. For details, please refer to "2.3 (II) AXT has no actual business, the reason for taking the licensing mode rather than transfer and the fairness of license royalties" in Q2.

In conclusion, the transfer price related to the patents between the Issuer and AXT is fair.

(II) How the amortization period of intangible assets is determined and whether the accounting treatment complies with the Accounting Standard for Business Enterprises

According to the Accounting Standard for Business Enterprises, the enterprises shall analyze and determine the useful life of the intangible assets upon acquisition. In case the intangible asset has a limited useful life, the Company shall estimate the useful life and amortize such intangible assets over the useful life in a systematic and reasonable manner. The amortization period of each intangible asset is listed in the following table:

Item

Estimated useful life

Amortization method

Basis

Land

50 years

Straight-line method

The amortization period is determined as the term of use specified in the real property ownership certificate is 50 years.

Software

10 years

Straight-line method

As the useful life is not specified in the contract, the amortization period is determined according to the period during which the intangible asset is expected to bring economic benefits.

Patents

6 years

Straight-line method

The amortization period is determined according to the period during which the intangible asset is expected to bring economic benefits.

8-1-1-284

The useful life of patents is determined according to the period during which it might bring economic benefits to the Company. The economic useful life of the patents owned by the Company at present is ten years, which was appraised by Armanino LLP, a US appraisal institution appointed by the Company. However, considering the lower cash inflow brought by such patents in six years and the uncertainty involved, the useful life of the patents is determined to be six years by the Company.

In conclusion, the accounting treatment for amortization of the intangible assets of the Company complies with the Accounting Standard for Business Enterprises.

Q15. R&D Expenses

According to the Prospectus, at the end of each year during the reporting period, the Issuer's R&D expenses amounted to RMB27,075,400, RMB26,826,400, RMB45,108,200 and RMB38,496,400, respectively, among which the amount of raw materials and finished goods consumed was RMB11,375,800, RMB12,136,000, RMB17,732,200 and RMB12,318,100 respectively.

The Issuer is required to explain: (1) the internal control system of R&D expenses, and the rationality and accuracy of the allocation among R&D expenses, operating costs and other period expenses; (2) the basis for assignment and management system of R&D staff during the reporting period; (3) the specific accounting items for raw materials and finished products consumed, the final destination of the results or related materials and finished products developed, and the accounting treatment method therefor; (4) the analysis of the reasons for the differences between the R&D expenses and the super deduction therefor under tax declaration.

The Sponsor and the Reporting Accountant are required to make verification and give express comments.

I. Explanation from the Issuer

(I) Internal control system of R&D expenses, and rationality and accuracy of the allocation among R&D expenses, operating costs and other period expenses;

1. Internal control system of R&D expenses

The Measures for the Administration of R&D Projects, the Financial Management System - R&D Expense Accounting System and other R&D-related internal control regulations were formulated and implemented by the Company with a view to enhancing and refining the management of R&D processes and R&D expenses. The Company has set out the scope of accounting for R&D expenses and regulated R&D activities including project approval, project progress follow-up and project acceptance in accordance with applicable provisions of the Accounting Standard for Business Enterprises and the Guidelines for the Administration of the Recognition of High- and New-Technology Enterprises.

The Finance Department of the Company has managed to ensure timely, accurate and complete recognition of various R&D expenses by establishing a separate accounting system for R&D expenses, setting up accounting items corresponding to R&D activities to account for the R&D expenses actually incurred, and establishing a ledger to recognize the expenses under R&D projects.

During the reporting period, the Company carried out R&D activities by relying on its relatively comprehensive internal controls for the accounting of various R&D expenses, and sound implementation thereof, in strict accordance with its internal control system regarding R&D.

2. Rationality and accuracy of the allocation among R&D expenses, operating costs and other period expenses

During the reporting period, the Company set out the scope of accounting for R&D expenses in accordance with applicable provisions of the Accounting Standard for Business Enterprises and the Financial Management System - R&D Expense Accounting System, among others. Such R&D expenses mainly consist of employee compensation, raw materials and finished goods consumed, depreciation and

8-1-1-286

amortization, utility bills, share-based payments and other expenses directly related to R&D activities. The specific scope of accounting is as follows:

(1) Employee compensation: such labor costs as the salaries, bonuses, social insurance premiums and housing provident fund of the Company's R&D staff; the compensation of R&D staff was classified as per R&D projects;

(2) Raw materials and finished goods consumed: the cost of raw materials and finished goods directly invested in R&D activities due to R&D demand;

(3) Depreciation and amortization: The R&D Department was provided with separate office space, and the depreciation of housings and buildings was apportioned based on the area of the office space; the depreciation of R&D equipment related to R&D activities was also included in R&D expenses;

(4) Utility bills: the cost of water and electricity used for R&D activities;

(5) Share-based payment: the amount of share-based payment corresponding to the participation of R&D staff in employee stock ownership platform, employee option incentive plan and controlling shareholder's equity incentive plan.

In addition to the above-mentioned expenses, such costs of demonstration, evaluation, acceptance and assessment of R&D results as well as the application fees, registration fees and agency fees for intellectual property rights and other expenses directly related to R&D activities, such as travel expenses and office expenses incurred by R&D staff for R&D activities, are also covered in the calculation of R&D expenses.

When the above-mentioned expenses were actually incurred, the Finance Department would determine whether to include the expenses so actually incurred in R&D expenses based on the scope and criteria of R&D expenses, and then credit the same into R&D expenses after checking against supporting documents corresponding to the amount of such R&D expenses. Those expenses that may be directly attributed to R&D projects or a certain department would be directly recognized as an expense; those indirect expenses or those expenses that may not be directly attributed to a certain project would be apportioned according to the working hours and workload of the

8-1-1-287

corresponding R&D staff.

In conclusion, the Issuer's R&D expenses were clearly accounted for and there was no unreasonable or inaccurate allocation among R&D expenses, operating costs and other period expenses.

(II) Basis for assignment and management system of R&D staff during the reporting period;

The Measures for the Administration of R&D Projects and the Regulations on the Management of R&D Staff have been formulated for the purpose of achieving effective management of R&D staff, which cover, among other things, the rights and obligations of R&D staff, the management of R&D tasks of R&D staff, the management of R&D results of R&D staff and the confidentiality obligations of R&D staff.

A dedicated R&D Department was set up by the Company, and the R&D staff were mainly responsible for the following (including without limitation): 1. the development of new technologies and new products to meet the market and customer demand for new products or new specifications; 2. continuous improvement and optimization of the existing process to improve the stability of the product processing process and production efficiency, reduce the costs and improve the production environment , etc.; 3. processing operation and process confirmation of R&D products, quality data collection and processing of R&D product processing process, and maintenance of R&D product processing equipment; 4. the provision of back-end technical support for downstream customers. At the time of applying for the approval of a R&D project, the participants of the R&D project and the expected duration of the R&D project would be specifically indicated, and such participants would be directly involved in the R&D activities.

The R&D staff of the Company were assigned on a reasonable basis, and properly classified for the accounting purpose. The R&D staff can be assigned accurately among various R&D projects, and there was no false increase or improper classification of R&D staff within the Company.

(III) Specific accounting items for raw materials and finished products consumed, final destination of the results or related materials and finished

8-1-1-288

products developed, and accounting treatment method therefor;

The amounts of raw materials and finished goods consumed by the Company for R&D activities during the reporting period were as follows:

In RMB0'000

Item

2021

2020

2019

Raw materials and finished goods consumed

2,894.58

1,773.22

1,213.60

The raw materials consumed under the Company's R&D expenses mainly referred to raw materials for R&D activities, including, among others, high-purity arsenic, high-purity gallium, InP polycrystal, boron trichloride and quartz materials, as well as chemical reagents, liquid nitrogen, materials for grinding, slicing and polishing and crucibles for long crystals. The specific accounting item of finished goods requisitioned during R&D process was mainly the PBN crucibles received by Beijing Boyu, a subsidiary of the Company, for R&D activities. The raw materials and finished goods consumed by the Company for R&D projects mainly aimed at upgrading and improving the Company's existing production processes, or developing new products and technologies, etc. The raw materials for R&D activities and the finished products mainly ended up being consumed during R&D activities, and then released to customers free of charge or sold in the form of R&D samples, or taken as wastes.

The R&D samples sent to customers for free during the R&D process are mainly samples of trial production in the R&D process. The purpose of the free samples is to allow end-user customers to give feedback on the company by using the R&D samples, which can help the company better achieve its R&D goals. Since such R&D samples do not meet the conditions for external sales and are trial production samples only, their purpose is to obtain production performance parameters of the samples, so that continuous optimization and improvement may be carried out subsequently. Therefore, the Company does not carry over such cost from the R&D expenses, which, instead, is accrued to the R&D expenses as incurred.

The value of the R&D samples formed during the R&D process that can be sold

8-1-1-289

to the public was accounted for based on the costs incurred during the R&D period and carried forward to the inventory for accounting; when the samples were sold to the public, the corresponding cost was carried forward and the corresponding selling revenue was recorded. During the reporting period, the amount of the external sales revenues and carry-over cost of the R&D samples is as follows:

(IV) Analysis of the reasons for the differences between the R&D expenses and the super deduction therefor under tax declaration;

During the reporting period, the amount of R&D expenses presented in the Company's reporting statements referred to the various expenses incurred during R&D process that were calculated and recognized as per R&D projects based on the Company's judgment over actual situation of R&D projects and in accordance with the Accounting Standard for Business Enterprises and the Certain Opinions of the Ministry of Finance on Strengthening the Financial Management of R&D Expenses by Enterprises (Cai Qi [2007] No. 194).

The R&D expenses qualifying for super deduction under tax declaration were prepared in accordance with the Circular on Improving the Policy on Pre-tax Super Deduction of Research and Development Expenses (Cai Shui [2015] No. 119), the Announcement on Issues Relating to the Policy on the Pre-tax Super Deduction of the Research and Development Expenses of Enterprises (STA Announcement [2015] No. 97), the Announcement on Issues Relating to the Scope of Pre-tax Super Deduction of Research and Development Expenses (Announcement [2017] No. 40), the Announcement of the Ministry of Finance, the State Taxation Administration and the Ministry of Science and Technology on Increasing the Ratio of Pre-tax Super Deduction of Research and Development Expenses (Cai Shui [2018] No. 99) and other norms.

There were some differences between R&D expenses and super deductions thereof

8-1-1-290

due to inconsistent calibers, which were attributed to accounting and taxation nature respectively. The amounts of differences between R&D expenses and super deductions thereof under tax declaration of the Company for 2019 and 2020 were shown as follows:

1. Super deductions not declared by certain subsidiaries

In 2019 and 2020, due to negative pre-tax profit or loss to offset on the part of some subsidiaries, the Company did not declare super deductions for R&D expenses incurred by them in the corresponding years for the sake of prudence.

2. Effect of offsetting related transactions in the consolidated financial statements

The Company maintained upstream and downstream synergistic production relationship with its subsidiaries, and purchased or sold some raw materials internally, certain of which were applied to R&D activities. Such related transactions were offset by the Company at the time of preparing the consolidated statements. R&D expenses reflected in the consolidated statements were measured at the ultimate purchasing cost of relevant raw materials, while the single company included the actual purchasing price under internal transactions into R&D expenses and applied for super deductions thereof, resulting in the differences between the R&D expenses and the super deduction therefor under tax declaration.

3. Share-based payment without super deductions

No super deduction was declared by the Company for the amount of share-based

8-1-1-291

payment corresponding to the participation of R&D staff in employee stock ownership platform, employee option incentive plan and controlling shareholder's equity incentive plan.

4. Building depreciation adjustment

In accordance with Item (1) of Article 1 of Cai Shui [2015] No. 119, the R&D expenses allowed for super deductions shall include depreciation expenses of instrument and equipment used for R&D activities. During the reporting period, the adjustment amounts of building depreciation for 2019 and 2020 were RMB127,000 and RMB186,600 respectively after excluding the depreciation expenses of housings, buildings, electronic equipment, etc. that were not the instrument and equipment used for R&D activities as stipulated by tax laws.

5. Others

The Company has not subjected other expenses directly related to the Company's R&D activities, such as costs of spare parts for process improvement of R&D projects, office expenses, travel expenses and other public expenses for R&D projects, to super deductions.

II. Intermediaries' verification procedure

(I) Verification procedure

In response to the foregoing, the Sponsor and the Reporting Accountant have implemented the following verification procedures:

1. Review the internal control documents of the Issuer concerning R&D expenses, and assess the effectiveness of the implementation thereof;

2. Review various systems of the Issuer governing R&D management, and have access to and examine the documents and information relating to major R&D projects of the Issuer during the reporting period, such as project approval forms, project completion reports, patent certificates and R&D project management practices;

3. Interview the person in charge of the R&D Department and the person in charge of the Finance Department to have a knowledge of the requisition process of R&D materials, the final destination of R&D materials requisitioned and the disposal of R&D

8-1-1-292

residuals, scraps and samples, and verify the compliance of the relevant accounting treatment with applicable provisions of the Accounting Standard for Business Enterprises;

4. Check the itemized statement of R&D expenses, randomly check the employees' payroll list and the bank slips thereof, have a knowledge of the composition and appointment or removal of R&D staff, and learn about their average salary level and the issuance thereof;

5. Obtain the details of raw materials and finished goods consumed, utility bills, share-based payment and other expenses under R&D projects, randomly check the material requisition forms, application for expenses, approval letters, invoices and payment vouchers, and verify the authenticity of the expenses and the accuracy of the expense recognition;

6. Obtain and double-check the depreciation and amortization computation lists of laboratory fixed assets machinery and equipment, office equipment and software intended for R&D;

7. Obtain the income tax computation and payment report of the Issuer for the reporting period, review the regulations on super deduction for R&D expenses and the scope of R&D expenses eligible for pre-tax super deduction, and make an alignment with R&D expenses.

(II) Verification opinions

Upon verification, the Sponsor and the Reporting Accountant believe that the internal control system of R&D expenses of the Company is reasonably designed and effectively implemented during the reporting period, that the R&D expenses of the Company are accurately recognized on an actual basis, and that the R&D expenses are calculated, apportioned, and measured in an accurate manner.

Q16. Internal Control

According to the submissions, during the reporting period, the Issuer had problems such as endorsement of negotiable instruments without commercial

8-1-1-293

substance, change of negotiable instruments, borrowings/loans with the related parties, and amounts received through related parties, etc.

The Issuer is required to explain: (1) the reason and rationality of amounts received through related parties, and whether there was financial disintermediation for the amount incurred during and after the reporting period, etc.; (2) the specific use and repayment of large value borrowings and loans during the reporting period, whether the agreed interest rate was in line with the market level, the reason for borrowing funds from AXT without bearing interest, and whether any costs and expenses were advanced by related parties.

The Sponsor and the Reporting Accountant are required to, in combination with the relevant requirements of the Questions and Answers on the Review of the Offering and Listing of Stocks on the STAR Market of the Shanghai Stock Exchange, explain the verification procedure, evidence and conclusion for the rectification and standardization of the Issuer's internal financial control and whether there was similar or other non-standardization circumstances after the deadline for initial audit filing.

Reply:

I. Explanations from the Issuer

(I) Reason and rationality of amounts received through related parties, and whether there was financial disintermediation for the amount incurred during and after the reporting period, etc.;

In 2019 and 2020, the Company had no amount received through related parties.

In March 2021, AXT-Tongmei, a subsidiary of the Company, undertook the overseas sales business and relevant customers from AXT. During the business handover, there were cases where both AXT-Tongmei and AXT had amounts receivable from the same customer. Due to factors such as the payment system of overseas customers, such customers may make payment only to a single entity. As a result, there were cases where AXT received amounts on behalf of the Company. In 2021, AXT

8-1-1-294

received RMB10,248,300 on behalf of AXT-Tongmei, which accounted for a small proportion in the current operating income and was commercially reasonable.

After AXT received the payment for the Company, it timely transferred the payment to AXT-Tongmei. AXT did not occupy the Company's funds, and there was no financial disintermediation. There have been no such cases since October 2021.

(II) Specific use and repayment of large value borrowings and loans during the reporting period, whether the agreed interest rate was in line with the market level, the reason for borrowing funds from AXT without bearing interest, and whether any costs and expenses were advanced by related parties;

8-1-1-295

and RMB1,982,900, respectively, in 2018, 2019 and 2021. The loans have been recovered in full. During the reporting period, the Company received from Maanshan Gallium the interest income amounting to RMB92,900, RMB93,200 and RMB46,100, respectively, in accordance with the loan agreement.

According to the loan agreement between the Company and Maanshan Jinmei, the loans were mainly used for organization costs related to the establishment of Maanshan Jinmei. The interest was accrued according to the benchmark interest rate of the People's Bank of China for the same period, and the agreed interest rate was in line with the market level.

2. Loans to HE Junfang

He Junfang is the general manager of Beijing Boyu, a subsidiary of the issuer, who is responsible for the daily operation of Beijing Boyu and holds 4.85% of the shares of the Company in total through Zhongke Hengye and Beijing Bomei.

In December 2017, Beijing Boyu and HE Junfang signed the loan contract, under which Beijing Boyu lent RMB2,000,000 to HE Junfang at the interest rate of 2.75%, with the term from December 1, 2017 to November 30, 2020; in January 2019, Beijing Boyu and HE Junfang signed the loan contract, under which Beijing Boyu lent RMB1,000,000 to HE Junfang at the interest rate of 2.75%, with the term from January 31, 2019 to December 31, 2024; in March 2020, Beijing Boyu and HE Junfang signed the loan contract, under which Beijing Boyu lent RMB1,000,000 to HE Junfang at the interest rate of 2.75%, and the interest rate was determined according to that of fixed deposits for the same period. HE Junfang provided the guarantee for the loans above by pledging 66.67% of shares held by him in Beijing Bomeilian.

Three loans above total RMB4,000,000, which were recovered in full in December 2020. The Company determined that the interest income payable by HE Junfang was RMB72,600 and RMB102,600, respectively, in 2019 and 2020 in accordance with the loan contracts, and collected such interest income in full in December 2020.

The loans mentioned above were mainly used for HE Junfang's personal purpose, including household expenses, decoration, tuition, loans between siblings, etc. The interest rate was determined according to that of fixed deposits for the same period, and

8-1-1-296

the agreed interest rate was in line with the market level.

3. Borrowings by AXT-Tongmei from AXT

AXT-Tongmei borrowed the funds from AXT in March 2021 for its initial operation, and borrowed RMB9,386,500 in aggregate from March to May 2021. The loan contract signed by and between AXT-Tongmei and AXT provides that no interest will accrue and no guarantee or pledge will be provided.

AXT-Tongmei was established in December 2020. When AXT-Tongmei was established, AXT held 100% of its equity interest. On May 6, 2021, the 2nd session of the first board of directors passed a resolution that Beijing Tongmei would acquire 100% equity interest in AXT-Tongmei from AXT in cash. On the same day, Beijing Tongmei and AXT entered into the Share Transfer Agreement, pursuant to which Beijing Tongmei would purchase all the shares of AXT-Tongmei from AXT.

Given borrowings by AXT-Tongmei from AXT were originally made within the AXT system, and to speed up the business operation of AXT-Tongmei and consummate the business handover, no interest payment was agreed. The Company acquired 100% equity interest in AXT-Tongmei from AXT to include AXT-Tongmei in the consolidated statements. As a result, as of June 30, 2021, the Company had a balance of funds to AXT within the scope of the Company's consolidated statements, continuing the borrowings. As of the date of this Reply, the above borrowings have been repaid.

In summary, during the reporting period, no related party bore costs and expenses for the Company or transferred any illegal interest.

II. The Sponsor and the Reporting Accountant are required to, in combination with the relevant requirements of the Questions and Answers on the Review of the Offering and Listing of Stocks on the STAR Market of the Shanghai Stock Exchange, explain the verification procedure, evidence and conclusion for the rectification and standardization of the Issuer's internal financial control and whether there was similar or other non-standardization circumstances after the deadline for initial audit filing.

(I) Rectification and standardization of the Company's internal financial

8-1-1-297

control

During the period, the non-standardization circumstances in connection with the Company's internal financial control were as follows:

1. Change of negotiable instruments

During the period, the change of negotiable instruments between the Company and customers in details is shown in the table below:

"Change to customers through negotiable instruments" means that the Issuer refunds change to customers by using negotiable instruments or by transfer when the face value of negotiable instruments actually paid by customers is more than the price for goods being collected by the Issuer and to be actually paid by the customers.

During the reporting period, the change of the Company's negotiable instruments amounted to RMB500,000, RMB1,589,900 and nil, respectively, which were relatively small. There was no dispute or claim between the Issuer and customers with regard to change of negotiable instruments, and the aforesaid negotiable instruments did not have a material adverse impact on the Issuer's normal production and business.

For change of negotiable instruments during the reporting period, the Company further established and improved internal control systems for administration of negotiable instruments, sales and collection, and purchase and payment. Since January 2021, the Company has no change of negotiable instruments, and the relevant systems have been effectively implemented.

2. Endorsement of negotiable instruments without commercial substance within the scope of consolidation

During the reporting period, the Issuer's parent company endorsed the negotiable instruments received from customers to Baoding Tongmei and Chaoyang Tongmei for payment to suppliers, with the amounts involved being RMB15,362,100, RMB3,881,800 and RMB4,401,100. The aforesaid endorsement of bank acceptance bills was not based on business backgrounds.

Regarding the endorsement of negotiable instruments without commercial substance with related parties during the reporting period, the Company further established and improved internal control systems for administration of negotiable instruments, sales and collection, and purchase and payment. Since February 2021, the Company has no endorsement of negotiable instruments without commercial substance with related parties, and the relevant systems have been effectively implemented.

3. Borrowings/loans between the Issuer and the related parties

For the offer of loans by the Issuer to its related parties Maanshan Gallium and HE Junfang and the borrowings by the Issuer from AXT during the reporting period, refer to Q16 "I. Explanations from the Issuer" hereof. Maanshan Gallium and HE Junfang had repaid the loans, the loan use was reasonable, the agreed interest rate was in line with the market level, and there have been no such cases later. Considering borrowings by AXT-Tongmei from AXT were originally in the AXT system, and to speed up the business operation of AXT-Tongmei and consummate the business handover, no interest payment was agreed. The Company acquired 100% equity interest in AXT-Tongmei from AXT to include AXT-Tongmei in the consolidated statements. As a result,

8-1-1-299

as of June 30, 2021, the Company had a balance of funds to AXT within the scope of the Company's consolidated statements, continuing the borrowings, which was reasonable, and there were no further new borrowings from AXT. As of the date of this Reply, the above borrowings have been repaid.

Regarding the borrowings/loans between related parties and the Issuer, the Company has further established and improved such systems and rules as the AOA, the Rules of Procedure for the General Meeting of Shareholders, the Rules of Procedure for the Board of Directors, the Work System for Independent Directors and the Decision-making System of Related Party Transactions, which specifically provide for decision-making authority, procedures and information disclosure of related party transactions, among others, and has established a relatively sound decision-making mechanism and supervision system.

4. Amounts received through related parties

In March 2021, AXT-Tongmei, a subsidiary of the Company, undertook the overseas sales business and relevant customers from AXT. During the business handover, there were cases where both AXT-Tongmei and AXT had amounts receivable from the same customer. Due to factors such as the payment system of overseas customers, such customers may make payment only to a single entity. As a result, there were cases where AXT received amounts on behalf of the Company. In 2021, AXT received RMB10,248,300 on behalf of AXT-Tongmei, which accounted for a small proportion in the current operating income and was commercially reasonable.

After AXT received the payment for the Company, it timely transferred the payment to AXT-Tongmei. AXT did not occupy the Company's funds, and there was no financial disintermediation. There have been no such cases since October 2021.

(II) Intermediaries' verification procedure

1. Verification procedure

The Sponsor and the Reporting Accountant have mainly carried out the following verification procedures with respect to the aforesaid issues:

(1) Review the relevant requirements of the Questions and Answers on the Review of the Offering and Listing of Stocks on the STAR Market of the Shanghai Stock

8-1-1-300

Exchange;

(2) Review the Company's bank loan contracts and the fund vouchers of bank loans;

(3) Review the Company's bills records to understand the endorsement of negotiable instruments;

(4) Review the subsidiary accounts of other payables, other receivables, long-term receivables, long-term payables and other items of the Company to understand the direct borrowings and loans between the Company and related parties or third parties, and referred to relevant contracts and fund vouchers, etc.;

(7) Interview the Chief Financial Officer of the Company to understand the rectification and standardization of internal financial control and whether there was similar or other non-standardization circumstances after the deadline for initial audit filing.

2. Verification opinions

Upon verification, the Sponsor and the Reporting Accountant believe that:

(1) The Company had such cases as change of negotiable instruments, endorsement of negotiable instruments without commercial substance within the scope of consolidation, borrowings/loans with related parties, and receipt of payment for cargoes through related parties during the reporting period, but has made rectification without such cases later. The receipt by the Company of amounts through the related party AXT was due to factors such as the payment system of overseas customers, which is commercially reasonable. After AXT received the payment for the Company, it

8-1-1-301

timely transferred the same to AXT-Tongmei. AXT did not occupy the Company's funds and there was no financial disintermediation. Both the amount and revenue proportion were small, without influence on the effectiveness of the Company's internal financial control operation. There have been no such cases since October 2021;

(2) For the above non-standardization, the Company has established targeted internal control system and effectively implemented it by correcting improper behavior, improving system and strengthening internal control;

(3) The defects and rectifications in the internal controls of the Company during the reporting period are disclosed in "IV. (I) Defects and rectifications in the internal controls of the Company during the reporting period" of "Section VII Corporate Governance and Independence" in the Prospectus.

(4) There is no follow-up impact of the aforementioned non-standardization and no major risk or hidden danger.

(5) The Company's internal financial control can continue to meet the normative requirements after the deadline of submitting the submissions for audit, and there is no case affecting the offering conditions.

1. Employee stock ownership platforms

8-1-1-303

(1) Specific content and implementation

On December 25, 2020, the Company granted equity interest to a total of 54 employees through four employee stock ownership platforms: Beijing Dingmei, Beijing Liaoyan, Boyu Yingchuang and Boyu Hengye. The employee stock ownership platforms become shareholders of the Company through capital increase;

In January 2022, MENG Fanwei, an incentive grantee of Boyu Yingchuang, and XI Jianhui, an incentive grantee of Boyu Hengye, resigned, and their shares (MENG Fanwei's contribution to Boyu Yingchuang is RMB90,000, accounting for 31.0345%; XI Jianhui's contribution to Boyu Hengye is RMB90,000, accounting for 10.7143%) were transferred to the employees WANG Xin and WANG Junyong respectively.

(2) Measurement method of fair value

As to the fair value regarding the employee stock ownership platform, taking the capital increase price for external investors introduced in January 2021 as a reference, the Company employed Shanghai PG Advisory Co., Ltd. for appraisal who has issued the consulting report P2021-1241, according to which the fair value per registered capital share was evaluated as RMB4.08. The specific calculation process is as follows:

In accordance with the Capital Increase Agreement and Supplementary Agreement executed by Beijing Tongmei and another 13 organizations including Haitong New Driving Force on November 13, 2020: 1) The capital increase price is RMB5.03 per share; 2) if Beijing Tongmei is not listed on the exchange by December 31, 2022, AXT needs to repurchase shares at the request of the share subscriber, and the repurchase commitment can be deemed as a put option. Shanghai PG Advisory Co., Ltd. has evaluated the option based on the Black-Scholes model, with the following main parameters:

1) Exercise probability, i.e., the probability that the issuer fails to go public on December 31, 2022: 50%;

2) Exercise price: RMB5.03 per share;

3) Option validity period: From November 13, 2020 to December 31, 2022;

4) Risk-free interest rate: Based on the yield rate of the bonds on the benchmark date of assessment on the maturity date of Chinese government bonds. In the event that

8-1-1-304

the exit event occurs less than one year ago, the yield rate with the same maturity period will be calculated by applying the interpolation method to Chinese government bonds;

5) Volatility: Based on the average value of historical stock price volatility of comparable companies with the same maturity period.

By substituting the foregoing parameters into the Black-Scholes model, it is estimated that the fair value of the put option is RMB0.95 per share, and then the fair value per unit of registered capital = 5.03-0.95 = RMB4.08 per share.

(3) Determination basis of vesting period

According to Article 18 of the Measures for Administration of Employee Stock Ownership of Beijing Tongmei Xtal Technology Limited, "The service period is 36 months from the date when an employee acquires the equity interest/property share of the employee stock ownership platform". The share-based payment confirmed by the employee stock ownership platform established by the Company will be amortized over 3 years.

(4) Calculation process of share-based payment

2. Option incentive

(1) Specific content and implementation

In November 2021, the Company granted 7,302,036 stock options to a total of 171 employees, including the Company's directors and executives, as well as the Company's core management, core technical personnel and core business personnel, but excluding independent directors and supervisors.

Vesting period and exercise arrangement: according to relevant provisions of the 2021 Stock Option Incentive Plan of Beijing Tongmei Xtal Technology Co., Ltd., the vesting period is 36 months commencing from the date of granting stock options. During the vesting period, the stock options granted to the incentive grantees under this Plan shall not be exercised. The stock options will be exercised in two batches upon expiry of 36 months after such options are granted. The percentage of options available for exercise with respect to each batch is 1/2 and 1/2 of the total amount of stock options granted. The stock options granted to the incentive grantees shall not be exercised before the Company's successful offering and listing.

Exercise price: according to the 2021 Stock Option Incentive Plan of Beijing Tongmei Xtal Technology Co., Ltd., the exercise price of the Incentive Plan is determined based on the transaction price of the most recent capital increase made by investors in Beijing Tongmei, and the exercise price is RMB5.03 per share.

Lock-up period and arrangement: incentive grantees shall not reduce their holdings within 3 years from the date on which the stocks are acquired from the exercise of the options after the Company is listed; after the expiration of the lock-up period, incentive grantees shall comply with the provisions with respect to the reduction of holdings by the Company's directors, supervisors and executives on a mutatis mutandis basis, and shall abide by the then applicable laws, regulations, regulatory documents

8-1-1-306

and the rules of the stock exchange where the Issuer is listed.

Up to now, incentive grantees MENG Fanwei (56,360 options granted) and LIU Lin (14,844 options granted) have left the Company; LIN Bin (21,560 options granted) and Dianna Huang (16,842 options granted) have voluntarily given up their options.

(2) Measurement method of fair value

For the fair value of equity interest under the option incentive plan, Shanghai PG Advisory Co., Ltd. employed by the Company appraised the fair value of the stock options granted on the grant date by adopting the binomial tree model and combining with the terms and conditions of stock option grant, and issued the consulting report P2021-1241.

(3) Determination basis of vesting period

According to Article 3 and Article 4, Chapter IV of the 2021 Stock Option Incentive Plan of Beijing Tongmei Xtal Technology Co., Ltd., "The vesting period is 36 months commencing from the date of granting stock options. During the vesting period, the stock options granted to the incentive grantees under this Plan shall not be exercised"; "The stock options will be exercised in two batches upon expiry of 36 months after such options are granted. The percentage of options available for exercise with respect to each batch is 1/2 and 1/2 of the total amount of stock options granted. Within the date on which applicable options are exercisable, subject to the fulfillment of the exercise conditions as stipulated in this Plan, an incentive grantee may exercise his/her granted stock options in two batches in accordance with the following table. The period available for the exercise of options is 12 months, and the starting date of the next exercise period shall not be earlier than the expiration date of the preceding exercise period, and should the exercise conditions of each batch of stock options have not been fulfilled, then the relevant rights and interests shall not be deferred to the next period". Therefore, the options granted by the Company are exercised in two batches, and the vesting period varies with the exercise date. The vesting period of the two batches of options is confirmed to be 3 years and 4 years respectively, and the relevant share-based payment is amortized separately.

3. Whether the relevant accounting treatment conforms to the provisions of the Accounting Standards for Business Enterprises

According to Article 6, Chapter II of the Accounting Standards for Business Enterprises No. 11 - Share-based Payments: if such equity-settled share-based payment in exchange for services received from employees could not be exercised until the completion of services for a vesting period, or until the achievement of a specified performance condition, at each balance sheet date during the vesting period, the services received for the current period shall be recognized as related costs or expenses and capital reserve, at an amount equal to the fair value of the equity instruments at the

8-1-1-308

grant date, based on the best estimate of the number of equity instruments expected to exercise. If, on the balance sheet date, subsequent information indicates that the number of equity instruments expected to exercise is different from that previously estimated, an adjustment shall be made to make it the number of equity instruments actually expected to exercise on the vesting date.

Since the stock options cannot be exercised on the grant date, there is no need for relevant accounting treatment as of that date. At each balance sheet date during the vesting period, the Company evaluated each batch of options separately, and recognized the services received for the current period as related costs or expenses and other capital reserves, at an amount equal to the fair value of the stock options at the grant date, based on the best estimate of the number of exercisable stock options. The above treatment principles are applicable to the employee stock ownership platform and the option incentive.

For the accounting treatment of the employees of the employee stock ownership platforms or the incentive grantees of options withdrawing from the employee stock ownership platforms and leaving during the reporting period, due to the vesting period stipulated for the Company's grant, the originally confirmed share-based payment related to the employees who have withdrawn from the employee stock ownership platforms or left shall be charged back to offset the share-based payment for the current period when they withdrew from the employee stock ownership platforms or left.

In view of the above, the accounting treatment for the employee stock ownership platform and the stock options by the Issuer conforms to the provisions of the Accounting Standards for Business Enterprises No. 11 - Share-based Payments.

(II) Accounting treatment by the controlling shareholder and the Issuer of the stock options and restricted stocks granted by AXT, the controlling shareholder, to employees of the Issuer, whether any incentivized employee held a position in the controlling shareholder or its subsidiary and the Issuer concurrently, and if yes, how to amortize the share-based payment;

1. Accounting treatment by the controlling shareholder of the stock options and restricted stocks granted

8-1-1-309

(1) Relevant rules in US GAAP

AXT, the controlling shareholder, is a NASDAQ-listed company in the United States and is governed by US GAAP.

On the grant date, in accordance with provisions under FASB ASC 718-10-30-3, relevant transactions with share-based payment shall be measured at the fair value. The value of goods or services exchanged with share-based payment instruments shall be determined based on the fair value of the equity instruments granted on the grant date. Therefore, AXT adopts the Black-Scholes model to estimate the fair value of the stock options on each grant date. The fair value of the restricted stock on the grant date is determined by its closing price on the same day.

In subsequent amortization, the number and amortization period of the equity instruments that are finally exercisable is stipulated by US GAAP stipulates as follows:

1) Number of equity instruments to be amortized

It is stipulated under FASB ASC 718-10-35-3 that in order to determine the share-based payment that should be recognized in each financial reporting period, the accounting subject may choose to estimate the number of equity instruments that are finally exercisable or recognize their effect only when they become invalid. AXT chooses the former, by which means the estimated number of equity instruments that are actually exercisable in the end is adjusted based on subsequent information on each balance sheet date. In accordance with the stock options and restricted stock terms granted by AXT to employees of the Issuer, as AXT has granted a waiting period, in the event of employment separation of any employee during the waiting period, on each balance sheet date, AXT will adopt the historical separation rate and other reference factors, to re-estimate the number of equity instruments that are finally exercisable, and amortize the fair value of the equity instruments that are finally exercisable.

2) Amortization period

It is stipulated under FASB ASC 718-10-35-8 that when the equity instruments granted have and only have the condition for the service period of vesting in batches, the entity may choose to make share-based payment based on the service period of each batch of vested equity instruments. The expenses can also be amortized based on the

8-1-1-310

longest service period of a batch. The equity instruments issued by AXT only have the service period condition. Therefore, AXT chooses to amortize the share-based payment based on the longest waiting period.

(2) Calculation process of the share-based payment for stock options and restricted stocks

During the reporting period, with regard to the stock options and restricted stocks granted by AXT, the controlling shareholder, to employees of the Issuer, AXT recognized share-based payments of RMB2.3041 million, RMB2.7837 million and RMB6.9109 million respectively. The specific calculation process is as follows:

1) Stock options

AXT granted the stock options to employees of the Issuer in November 2015, January 2016 and October 2016 respectively. The amortization and calculation processes of its share-based payment expenses in 2019 and 2020 are as follows:

2. Accounting treatment by the Issuer of the stock options and restricted stocks granted

(1) The share-based payment is treated as equity settlement

According to Item II, Q7 of the Interpretation of Accounting Standards for Business Enterprises No. 4, if no settlement obligation is imposed on the enterprise receiving services or the enterprise's equity instruments are granted to its staff, the share-based payment shall be treated as equity settlement; if any settlement obligation is imposed on the enterprise receiving services and the equity instruments of another enterprise subordinate to the group are granted to its staff, the share-based payment shall be treated as cash settlement.

AXT, the controlling shareholder, grants employees of the Issuer stock options and restricted stocks. The Issuer has no settlement obligation, so the share-based payment should be treated as equity settlement.

(2) Accounting treatment by the Issuer

According to Article 6, Chapter II of the Accounting Standards for Business Enterprises No. 11 - Share-based Payments: if such equity-settled share-based payment in exchange for services received from employees could not be exercised until the

8-1-1-313

completion of services for a vesting period, or until the achievement of a specified performance condition, at each balance sheet date during the vesting period, the services received for the current period shall be recognized as related costs or expenses and capital reserve, at an amount equal to the fair value of the equity instruments at the grant date, based on the best estimate of the number of equity instruments expected to exercise. If, on the balance sheet date, subsequent information indicates that the number of equity instruments expected to exercise is different from that previously estimated, an adjustment shall be made to make it the number of equity instruments actually expected to exercise on the vesting date.

Since the stock options and restricted stocks cannot be exercised on the grant date, there is no need for relevant accounting treatment. At each balance sheet date during the vesting period, the Company evaluated each batch of stock options and restricted stocks separately, and recognized the services received for the current period as related costs or expenses and other capital reserves, at an amount equal to the fair value of the stock options at the grant date, based on the best estimate of the number of stock options expected to exercise.

For the accounting treatment of the incentive grantees of stock options and restricted stocks leaving during the reporting period, due to the vesting period stipulated for the controlling shareholder's grant, the originally confirmed share-based payment related to the employees who have left shall be charged back to offset the share-based payment for the current period when they left.

During the reporting period, regarding the grant of stock options and restricted stocks by AXT, the controlling shareholder, to employees of the Issuer, the Issuer confirmed that the amount of share-based payment was RMB2,304,100, RMB2,783,700 and RMB6,910,900 respectively.

3. Whether any incentivized employee held a position in the controlling shareholder or its subsidiary and the Issuer concurrently, and if yes, how to amortize the share-based payment;

All the incentivized employees are employees of the Issuer, and there is no case where any incentivized employee held a position in the controlling shareholder or its

8-1-1-314

subsidiary and the Issuer concurrently.

(III) Positions of shareholders having contributed to the capital increase in the Company in December 2020, whether it constitutes share-based payment and the basis

1. Positions of shareholders having contributed to the capital increase in the Company in December 2020

On December 25, 2020, Tongmei Limited held a shareholders' meeting, agreeing to increase the Company's registered capital from RMB301,106,668.53 to RMB820,960,319. The newly added registered capital comprises RMB516,569,800, which was subscribed by AXT, Jinchao Business Management, Beijing Bomeilian, and Zhongke Hengye in the form of equity, and RMB3,283,841, which was subscribed by Beijing Liaoyan, Beijing Dingmei, Boyu Yingchuang, and Boyu Hengye in the form of cash.

(1) The act of AXT, Jinchao Business Management, Zhongke Hengye and Beijing Bomeilian does not constitute share-based payment

According to the Accounting Standards for Business Enterprises No. 11 - Share-based Payments and relevant interpretation, share-based payment refers to the transaction in which an enterprise grants equity instruments or assumes liabilities determined on the basis of equity instruments in order to receive services from employees or other parties. According to the definition, whether the transfer of shares or issuance of new shares by the Company during the reporting period constitutes share-based payment can be judged from the following two aspects: I. whether the Issuer has exchanged services from employees or other parties, including issuing shares to employees or specific suppliers at a low price in exchange for services; II. whether there is a large difference between equity transaction price and fair value.

As per the reply on share-based payments in the Certain Questions and Answers

8-1-1-324

on IPO Business, "Under normal circumstances, changes of shares resulting from regulatory measures such as resolution of nominee holdings of shares, non-transaction conduct such as property division among family, succession, and donation, asset restructuring, mergers and acquisitions, changes of shareholding manners, placement of new shares with existing shareholders in the same proportion, or the like generally need not be treated as share-based payments if there is sufficient evidence that the acquisition of the relevant shares is irrelevant to the issuer's acquisition of services."

In December 2020, AXT, Jinchao Business Management, Zhongke Hengye and Beijing Bomeilian acquired the Issuer's equity interest through equity capital increase, which is not a share-based payment mainly for the following reasons: the contribution made by AXT, Jinchao Business Management, Zhongke Hengye and Beijing Bomeilian to the capital increase of the Issuer with the equity interest in five companies such as Beijing Boyu is the Issuer's act of asset reorganization to solve the problem of horizontal competition and improve the comprehensive strength of the Company, but not to receive the services provided by the parties contributing to the capital increase to the Company. The Issuer has not agreed on any service matters with the above parties for the issue, so there is no case where the Issuer issues shares in exchange for the services from the transferee.

(2) The act of Beijing Liaoyan, Beijing Dingmei, Boyu Yingchuang and Boyu Hengye constitutes share-based payment

In order to realize that employees share the achievements of the Company and for the purpose of motivating employees, the Company sets up employee stock ownership platforms to realize employee stock ownership based on the principle of voluntariness and assumption of risk. Employees add capital to the Company through four employee stock ownership platforms: Beijing Liaoyan, Beijing Dingmei, Boyu Yingchuang and Boyu Hengye. The Company has confirmed the share-based payment of RMB2,657,600 in 2021 for the capital increase through the above employee stock ownership platforms.

The share changes of the employee stock ownership platforms are subject to the Accounting Standards for Business Enterprises No. 11 - Share-based Payments, and the

8-1-1-325

relevant accounting treatment is in accordance with the relevant provisions of the Accounting Standards for Business Enterprises.

(IV) Basis and accuracy of amortization of share-based payment among costs and expenses.

According to the department, work content and nature of the incentivized employees, the Company calculated the share-based payment expenses for each incentivized employee and included the same into corresponding costs, selling expenses, management expenses or R&D expenses. For motivated employees who may undertake multiple work contents and natures, the company determines the nature of their work based on their attendance and work records, and share-based payment expenses are amortized in different expenses according to the attendance records.

According to the Company's attendance and work records, most of motivated objects have fixed positions during the reporting period, who do not hold different positions in the same year; a small number of them are allocated to different positions as needed for their own positions and the Company's production. The Company amortizes their remunerations in different expenses according to their working hours based on the attendance records.

During the reporting period, the Company's share-based payments by expense type are as follows:

In RMB0'000

By expense type

To sum up, the share-based payment expenses of the Company during the reporting period were amortized on a reasonable basis and in an accurate amount.

II. Intermediaries' verification

(I) Verification procedure

8-1-1-326

The Reporting Accountant and the Sponsor have carried out the following verification procedures with respect to the aforesaid issues:

1. Review relevant documents including, among others, the resolutions of the board of directors and the general meeting of shareholders, and the corresponding plan and partnership agreements related to the implementation by the Company of the employee stock ownership plan and the equity incentive plan, and confirm the grantees, grant price, grant time, lock-in period and tenure in connection therewith;

2. Review the appraisal report issued by Shanghai PG Advisory Co., Ltd.;

3. Combined with the previous equity changes to review the accounting treatment process of share-based payment, whether it conforms to the relevant provisions of the Accounting Standards for Business Enterprises, and whether the Accounting Standards for Business Enterprises No. 11 - Share-based Payments is applicable to the relevant share changes;

4. Review the implementation of the Issuer's equity incentive plan, introduce internal valuation experts of the Reporting Accountant to evaluate the rationality and fairness of the measurement methods of fair value of relevant equity instruments and the calculation process of share-based payment, check the period in which share-based payment is included, and verify whether the accounting treatment of share-based payment conforms to the provisions of accounting standards for enterprises;

(II) Verification opinions

Upon verification, the Sponsor and the Reporting Accountant believe that the related share-based payment contents disclosed by the Company are true, complete and accurate, the accounting treatment of share-based payment contents is reasonable, and the amortization and measurement of share-based payment are reasonable and accurate.

Q18. Fundraising Project

According to the Prospectus, the Issuer intends to raise about RMB1.16 billion, of which RMB800 million will be used to replenish working capital.

8-1-1-327

The Issuer is required to explain: the reason and rationality for using the majority of the raised funds to replenish working capital, and the specific arrangements for the investment of the raised funds in the field of scientific and technological innovation.

Reply:

I. Explanations from the Issuer

(I) Reason and rationality for using the majority of the raised funds to replenish working capital

1. Necessity and rationality for using the raised funds to replenish working capital

The Company's current cash and bank balances are mainly used for daily raw material and equipment procurement, goods preparation, project R&D and other related expenses, project expenses, expenses related to business activities such as receiving labor services and paying employee compensation, taxes and fees, as well as expenses related to long-term development. With the continuous growth of the Company's production capacity and income scale, the Company's expenditure on raw material procurement, R&D and employee compensation will further increase, so it is urgent to raise more funds to meet the working capital needs.

In this Offering, RMB800 million will be raised to replenish working capital, mainly because that, on the one hand, with the continuous growth of the Company's income scale, the Company's demand for raw material procurement has increased correspondingly, and the expenditure on R&D and investment in projects have also kept increasing, which is expected to produce the demand for working capital investment; on the other hand, the rapid development of the market requires the Company to continue to pay attention to changes in market demand and expand core technological advantages, the Company still has the demand for further R&D to launch new products in the future, and it is expected to increase the demand for working capital investment. In addition, with the gradual investment, construction and operation of the Company's fundraising projects, and with the continuous improvement of the Company's overall

8-1-1-328

business scale, the demand for working capital is further increasing.

When the working capital is in place, it will provide sufficient working capital for the Company's project construction, avoid the dilemma of cash flow shortage caused by the increase of capital expenditure, and meet the needs of the Company's long-term development. At the same time, the increase of working capital is conducive to improving the Company's anti-risk ability, avoiding serious adverse impact on the Company's going-concern ability due to price fluctuations of raw materials and finished products and fluctuations in exchange rate, and ensuring the stability of the Company's main business. In addition, in order to adapt to the trend of rapid development of industry technology and the need for continuous upgrading of product performance, the Company will continue to carry out technological transformation of production lines and new product R&D in the future, which requires the Company to have strong financial strength. The use of the raised funds will help optimize the capital structure of the Company, improve the anti-risk ability, provide financial support for the sustainable development of the Company's business, and provide a strong guarantee for the implementation of the Company's future development strategy.

2. Process by which the raised funds are used to replenish working capital

The amount occupied by working capital is mainly affected by the Company's operating current assets and operating current liabilities. The Company uses the sales percentage method to estimate the changes of relevant current assets and current liabilities caused by the growth of future operating income, and then estimates the working capital gap in the next three years.

The Company has forecast the operating current assets and operating current liabilities at the end of 2022, 2023 and 2024, and calculated the amount of operating current capital at each end of the year (i.e. the difference between operating current assets and operating current liabilities). The percentage of operating current assets (accounts receivable, notes receivable, receivables financing, prepayments, inventory) and operating current liabilities (accounts payable, contract liabilities) in operating income is determined according to the average of actual indicators in 2019-2021.

The Company's new working capital gap in the next three years is calculated as

8-1-1-329

per the following formula:

New working capital gap = Amount of working capital occupied at the end of 2024 - amount of working capital occupied at the end of 2021

According to the above calculation, the Company's new working capital demand in the next three years amounts to RMB869.0666 million. It is reasonable for the Company to use the raised funds of RMB800 million to replenish the working capital.

To sum up, the Company calculates its working capital gap in the next three years using the sales percentage method, based on reasonable assumptions and parameters setting, and in accordance with rational calculation process. The amount of RMB800 million to be used by the Company for replenishing working capital is in line with its existing assets and business scale.

(II) Specific arrangements for the investment of the raised funds in the field of scientific and technological innovation

According to the Guidelines on the Industrial Classification for the Listed Companies (2012 Revision) published by the CSRC, the industry of the Company is classified into the "computer, communication and other electronic equipment manufacturing industry (industrial code: C39)."

According to the Tentative Provisions for Application for and Recommendation of Listing of Enterprises on the Sci-tech Innovation Board of the Shanghai Stock Exchange, the Company is classified into a new generation of information technology industry in line with the positioning of the STAR Market.

8-1-1-330

customers' orders, improve the supply capacity, consolidate the Company's competitive position in the market, meet customers' demand for products of larger quantities, faster delivery and higher quality, and lay a solid foundation for the Company's continuous growth.

Reply:

I. Explanations from the Issuer

(I) Basis and process of the calculation of the Issuer's estimated market value

1. Selection of evaluation methods

Enterprise value evaluation methods include market method, cost method and income method, etc. The characteristics and applicability of these methods are as follows:

Valuation Method

Introduction

Indicator

Feature

Market method

Comparable companies with the same or similar operating conditions and main business must be found in an active public market

PE ratio

Simple in calculation, easy in data acquisition and high in comprehensiveness, but not suitable for value assessment of loss-making enterprises

PB ratio

Applicable to loss-making companies, but vulnerable to accounting policies and not applicable to most high-tech companies

PS ratio

Wide in applicability, but unable to reflect business costs

EV/EBITDA

Applicable to heavy-asset industries with large depreciation and amortization amount or high-debt enterprises with high interest amount

Cost method

The cost of repurchasing a brand-new asset similar or identical to the asset being appraised is estimated from the buyer's perspective

Advantages: data availability, wide applicability

Disadvantages: the synergistic effects between corporate assets and the value of intangible assets are neglected, and the future development potential of the company is not reflected

8-1-1-348

Income method

Through the forecasting of the expected return of the asset, the value is assessed by means of discounting

Advantages: comprehensive assessment of enterprise value

Disadvantage: difficulty in acquisition and estimation of the measurement data

The Company is a world-renowned semiconductor material technology company, mainly engaged in the research and development, production and sales of indium phosphide substrates, gallium arsenide substrates, germanium substrates, PBN materials and other high-purity materials. Its products have broad application space in 5G communications, data centers, next-generation displays, artificial intelligence, unmanned driving, wearable devices, aerospace and other fields.

The Company had operating incomes of RMB857 million in 2021, and had net profits attributable to shareholders of the parent company amounting to RMB94,587,600. Both sales revenue and net profits have reached a certain scale. Therefore, the PS (price-to-sales ratio) method has been selected for the valuation by the Company.

2. Selection of comparable companies

The company is mainly engaged in the research and development, production and sales of InP, GaAs, germanium substrate materials, PBN materials and high-purity gallium. Therefore, the company chooses A-share listed companies Leon Micro, NSIG, San'an Optoelectronics, Yunnan Germanium Industry and SICC as comparable companies for the comparison of the enterprise value valuation. Details are as follows:

Based on industry development and the PS (TTM) range of comparable companies, Beijing Tongmei's PS (TTM) was forecast to be in the range of 24-28x, so the Company's reasonable market value was predicted to be in the range of RMB20.568 billion ~

8-1-1-350

23.996 billion.

(II) Other methods to estimate market value for confirmatory analysis

In addition to estimating the company's market value using the market method-PS (price-to-sales ratio) method, the company also analyzed the latest external financing, as follows:

On January 21, 2021, Tongmei Limited held a shareholders' meeting and agreed to increase the company's registered capital from RMB820,960,319 to RMB885,426,756, and the newly increased registered capital was to be subscribed by Haitong New Driving Force, Haitong New Energy, Haitong Innovation, Anxin Industrial Investment, Jinggangshan Meicheng, Huadeng II, Qingdao Xinxing, Qiji Hangzhou, Gongqingcheng Yihua, Shangrong Baoying, Xiamen Heyong, Hangzhou Jingyue, and Lumentime Semiconductor, and it was agreed that the shareholder Zhongke Hengye would transfer the registered capital of RMB10,463,911 to Liaoning Zhuomei at a price of RMB52,655,928, and that the shareholder Beijing Bomeilian would transfer the registered capital of RMB4,907,343 to AXT at a price in RMB equivalent to USD3,730,000. The capital increase and transfer price was RMB5.03/registered capital.

According to the above-mentioned Issuer's external financing price, the Issuer's post-investment valuation of this external financing is RMB4.454 billion.

(III) Differences in the valuation of securities markets between China and the United States

Due to the differences in laws, regulations and regulatory concepts between China and the United States, the company and AXT will have certain differences in specific accounting treatment and financial information disclosure due to the application of different accounting standards and different regulatory requirements. At the same time, due to the differences in the information disclosure requirements of listed companies by the securities regulatory authorities and the differences in language, culture, and expression habits, as well as the composition of investors in China and the United States, the investment philosophy of the semiconductor industry, and the specific conditions of the capital market, There would be discrepancies in the AXT's market capitalization on

8-1-1-351

the NASDAQ market and the Issuer's estimated market capitalization on the China Science and Technology Innovation Board. At present, relevant information about some companies that have completed the US stock split in the market is as follows:

Note: The foregoing valuation is the secondary market value as of April 8, 2022, and the relevant market value of the listed subject in the US stock market is converted at the USD-RMB exchange rate on April 8, 2022.

Thus, due to the foregoing reason, the market value of companies with US stock split in the A shares market is generally higher than their valuations in the US stock market.

(IV) Rationality of estimated market value

Benefiting from the favorable factors of industry development, the Issuer has a prominent market position and outstanding growth potential. The Issuer has reliable public market data comparable to A-share listed companies, and the PS (price-to-sales ratio) (TTM) valuation indicator selected in the market approach is reasonable and reliable.

Considering the above-mentioned latest external financing situation and the analysis of comparable companies in the same industry, the Issuer is expected to have a market value of not less than RMB3 billion when it goes public.

20.3
