The following discussion and analysis of our financial condition and results of operations should be read together with our condensed financial statements and related notes elsewhere in this Quarterly Report and our audited financial statements and the related notes and the discussion under the heading "Management's Discussion and Analysis of Financial Condition and Results of Operations" in our Annual Report on Form 10-K for the fiscal year ended December 31, 2020 filed with the SEC on March 30, 2021 (Annual Report). Some of the information contained in this discussion and analysis or set forth elsewhere in this Quarterly Report, including information with respect to our plans and strategy for our business and related financing, includes forward-looking statements that involve risks and uncertainties. As a result of many factors, including those factors set forth in the "Risk factors" section of this Quarterly Report, our actual results could differ materially from the results described in or implied by the forward-looking statements contained in the following discussion and analysis. You should carefully read the "Risk factors" section of this Quarterly Report to gain an understanding of the important factors that could cause actual results to differ materially from our forward-looking statements. Please also see the section entitled "Special note regarding forward-looking statements."

Management's Discussion and Analysis of Financial Condition and Results of Operations (MD&A) is designed to provide material information relevant to an assessment of our financial condition and results of operations, including an evaluation of the amounts and certainty of cash flows from operations and from outside sources. This section is designed to focus on material events and uncertainties known to management that are reasonably likely to cause reported financial information not to be necessarily indicative of future operating results or of future financial condition. This includes descriptions and amounts of matters that have had a material impact on reported operations, as well as matters that are reasonably likely based on management's assessment to have a material impact on future operations.

Overview

Our primary focus is to transform diagnostic testing through innovative molecular diagnostic products that enable customers to deploy accurate, reliable, low-cost and rapid molecular testing at the point-of-care for infectious diseases and other conditions.

We are developing the Talis One system which leverages expertise across chemistry, biology, engineering and software to create a fully integrated, cloud-enabled and portable molecular diagnostic solution that customers can rapidly deploy when and where needed. The Talis One system incorporates core proprietary technologies into a compact, easy-to-use instrument, that utilizes single use test cartridges and software, including a central cloud database, which are designed to work together to provide levels of testing accuracy equivalent to a central laboratory. We intend to commercialize the Talis One system as an integrated solution comprising single use consumables, an instrument and software. Our commercial strategy will focus on building and expanding an installed base of Talis One instruments and driving utilization of our Talis One assay kits to generate revenue from the purchase of such products. Subject to marketing authorization, our first commercial test will be a rapid point-of-care molecular diagnostic to detect SARS-CoV-2 directly from a patient sample in less than 30 minutes (COVID-19 test). We are also developing assays for the detection of other respiratory infections that could be included as a panel test with our COVID-19 test as well as tests for infections related to women's health and sexually transmitted infections.

Our products will require marketing authorization from the FDA prior to commercialization. Due to the COVID-19 global pandemic, we are pursuing marketing authorization for our COVID-19 test under an emergency use authorization (EUA) rather than initially pursuing 510(k) clearance or other forms of marketing authorization under the FDA's standard medical device authorities.

We have invested in automated cartridge manufacturing lines capable of producing one million Talis One cartridges per month. The first of such lines was delivered in the first quarter of 2021, and we expect will scale to meet demand through 2021. These manufacturing lines are located at our contract manufacturers' sites and are operated by our contract manufacturing partners. We have also ordered 5,000 Talis One instruments from our instrument contract manufacturer.

Since our inception in 2013, we have devoted substantially all our efforts to research and development activities, manufacturing capabilities, raising capital, building our intellectual property portfolio and providing general and administrative support for these operations. We have principally financed our operations through the issuance and sale of shares of our convertible preferred stock to outside investors in private equity financings as well as the issuance of convertible promissory notes and receipts from government grants. Prior to our initial public offering we received $351.5 million from investors in our preferred stock financings and the sale of convertible promissory notes that converted in such financings. Additionally, on February 17, 2021, we raised $232.5 million through an initial public offering (IPO) to finance operations going forward.



                                       19

--------------------------------------------------------------------------------

We have incurred recurring losses since our inception, including net losses of $125.0 million for the six months ended June 30, 2021 and $17.4 million for the six months ended June 30, 2020. As of June 30, 2021, we had an accumulated deficit of $297.9 million. We expect to continue to generate operating losses and negative operating cash flows for the foreseeable future if and as we:



    •   continue the research and development of our platform and assays for
        additional diseases;


    •   initiate clinical trials for, or additional preclinical development of,
        our platform;


  • further develop and refine the manufacturing processes for our platform;


  • change or add manufacturers or suppliers of materials used for our platform;


  • seek marketing authorizations;


  • seek to identify and validate diagnostic assays for other disease states;


  • obtain, maintain, protect and enforce our intellectual property portfolio;


  • hire and deploy a salesforce;


  • seek to attract and retain new and existing skilled personnel;


    •   create additional infrastructure to support our operations as a public
        company and incur increased legal, accounting, investor relations and
        other expenses; and


  • experience delays or encounter issues with any of the above.

In addition, if we obtain marketing authorization for our platform, we expect to incur significant commercialization expenses related to product manufacturing, marketing, sales and distribution. As a result, we will need substantial additional funding to support our operating activities. Until such time as we can generate significant revenue from product sales, if ever, we expect to finance our operating activities through a combination of equity offerings, debt and grant revenue. Adequate funding may not be available to us on acceptable terms, or at all.

If we are unable to obtain funding, we will be forced to delay, reduce or eliminate some or all of our research and development programs, product portfolio expansion or commercialization efforts, which could adversely affect our business prospects, or we may be unable to continue operations. Although we continue to pursue these plans, there is no assurance that we will be successful in obtaining sufficient funding on terms acceptable to us to fund continuing operations, if at all.

As of June 30, 2021, we had unrestricted cash and cash equivalents of $313.5 million. We expect that our cash and cash equivalents of $313.5 million as of June 30, 2021 will be sufficient to fund our operations through at least the next 12 months from the date our condensed financial statements are issued. We may need substantial additional funding to support our continuing operations and pursue our long-term business plan. We may seek additional funding through the issuance of our common stock, other equity or debt financings, or collaborations or partnerships with other companies. The amount and timing of our future funding requirements will depend on many factors, including the pace and results of our research efforts for our assays and development and manufacturing activities. We may not be able to raise additional capital on terms acceptable to us, or at all. Any failure to raise capital as and when needed would compromise our ability to execute on our business plan and may cause us to significantly delay or scale back our operations.

We outsource essentially all of our manufacturing. Design work, prototyping and pilot manufacturing are performed in-house before outsourcing to third party contract manufacturers. Our outsourced production strategy is intended to drive rapid scalability and avoid the high capital outlays and fixed costs related to constructing and operating a manufacturing facility. Certain of our suppliers of components and materials are single source suppliers. To support our anticipated commercial launch, we have invested in automated cartridge manufacturing production lines for our Talis One cartridges. Those assets deemed to have an alternative future use have been capitalized as property and equipment while those assets determined to not have an alternative future use have been expensed. The automated cartridge manufacturing lines are capable of producing one million Talis One cartridges per month, which we expect will scale to meet demand through 2021.

COVID-19 pandemic

Since it was reported to have surfaced in December 2019, a novel strain of coronavirus (COVID-19) has spread across the world and has been declared a pandemic by the World Health Organization. Efforts to contain the spread of COVID-19 have intensified and governments around the world, including in the United States, Europe and Asia, have implemented travel restrictions, social distancing requirements, stay-at-home orders and have delayed the commencement of non-COVID-19-related clinical trials, among other restrictions. As a result, the current COVID-19 pandemic has presented a substantial public health and economic challenge



                                       20

--------------------------------------------------------------------------------

around the world and is affecting our employees, patients, communities and business operations, as well as contributing to significant volatility and negative pressure on the U.S. economy and in financial markets.

We expect that COVID-19 precautions will directly or indirectly impact the timeline for some of our planned clinical trials for our non-COVID-19 related products in development and we are continuing to assess the potential impact of the COVID-19 pandemic on our current and future business and operations, including our expenses and clinical trials, as well as on our industry and the healthcare system.

As a result of the outbreak, many companies have experienced disruptions in their operations and in markets served. We are considered an essential business and therefore the impact to our operations has been limited. To date, we have initiated some and may take additional temporary precautionary measures intended to help ensure our employees' well-being and minimize business disruption. For the safety of our employees and their families, we have temporarily reduced the presence of our employees in our facilities. Certain of our third-party service providers have also experienced shutdowns or other business disruptions. We are continuing to assess the impact of the COVID-19 pandemic on our current and future business and operations, including our expenses and planned clinical trial and other development timelines, as well as on our industry and the healthcare system.

As a result of the COVID-19 pandemic, or similar pandemics and outbreaks, we have and may in the future experience severe disruptions, including:



    •   interruption of or delays in receiving products and supplies from the
        third parties we rely on to, among other things, manufacture components of
        our instruments, due to staffing shortages, production slowdowns or
        stoppages and disruptions in delivery systems, which may impair our
        ability to sell our products and consumables;


    •   limitations on our business operations by the local, state, or federal
        government that could impact our ability to sell or deliver our
        instruments and consumables;


    •   delays in customers' purchasing decisions and negotiations with customers
        and potential customers;


    •   business disruptions caused by workplace, laboratory and office closures
        and an increased reliance on employees working from home, travel
        limitations, cyber security and data accessibility limits, or
        communication or mass transit disruptions; and


    •   limitations on employee resources that would otherwise be focused on the
        conduct of our activities, including because of sickness of employees or
        their families or the desire of employees to avoid contact with large
        groups of people.

Three vaccines for COVID-19 have been authorized for emergency use by the FDA as of June 2021. There has been a recent drop in COVID-19 testing volumes in the U.S. There can be no assurance that demand for our COVID-19 testing will continue to exist in the future due to successful containment efforts, the successful vaccination of a majority of Americans, or due to other events.

Enterprise Resource Planning

During the six month period ending June 30, 2021, we implemented a new enterprise resource planning (ERP) system to provide better information and to support our commercial scale-up.

Components of our results of operations

Grant revenue

To date, all of our revenue has been derived from government grants, which includes an April 2018 subaward grant from Boston University as part of the CARB-X initiative, a May 2018 grant from the NIH to support our advancement of a Diagnostics via Rapid Enrichment, Identification, and Phenotypic Antibiotic Susceptibility Testing of Pathogens from Blood project (NIH grant), a July 2020 subaward grant from the University of Massachusetts Medical School for Phase 1 of the NIH's Rapid Acceleration of Diagnostics - Advanced Technology Platforms (RADx) initiative and a contract from the NIH directly for Phase 2 of the RADx initiative.

In July 2021, the Company and the NIH agreed to an amended contract for the completion of the RADx initiative. The amendment extended the contract to October 31, 2021, and decreased the potential payment for the remaining milestone from $7.9 million to $4.0 million. The remaining $4.0 million available under the amended RADx contract is contingent upon us meeting our agreed-upon contractual milestone.

Under the CARB-X and NIH grants there is the possibility of an additional $2.8 million and $2.1 million, respectively, through April 2023.



                                       21

--------------------------------------------------------------------------------

These grants are not in scope of the contracts with customers accounting guidance as the government entities and/or government-sponsored entities are not customers under the agreements.

Grant funds received from third parties are recorded as revenue if we are deemed to be the principal participant in the arrangement. If we are not the principal participant, the funds from grants are recorded as a reduction to research and development expense. Reimbursable costs paid prior to being billed are recorded as unbilled grant receivables. Funds received in advance are recorded as deferred grant revenue. Our management has determined that we are the principal participant under our grant agreements, and accordingly, we record amounts earned under these arrangements as grant revenue.

Operating expenses

Research and development expenses

Research and development expenses consist primarily of internal and external costs incurred for our research activities, the development of our platform, investment in manufacturing capabilities as well as costs incurred pursuant to our government grants and include:



    •   salaries, benefits and other related costs, including stock-based
        compensation expense, for personnel engaged in research and development
        functions;


    •   the cost of laboratory supplies and developing and manufacturing of our
        platform;


    •   contract services, other outside costs and costs to develop our technology
        capabilities;


    •   facility-related expenses, which include direct depreciation costs and
        allocated expenses for rent and maintenance of facilities and other
        operating costs;


    •   cost of outside consultants, including their fees and related travel
        expenses, engaged in research and development functions;


  • expenses related to regulatory affairs; and


  • fees related to our scientific advisory board.

We expense research and development costs as incurred. Costs for external development activities are recognized based on an evaluation of the progress to completion of specific tasks using information provided to us by our vendors. Payments for these activities are based on the terms of the individual agreements, which may differ from the pattern of costs incurred, and are reflected in our financial statements as prepaid or accrued research and development expenses. Nonrefundable advance payments for goods or services to be received in the future for use in research and development activities are recorded as prepaid expenses and expensed as the related goods are delivered or the services are performed.

Until future commercialization is considered probable and the future economic benefit is expected to be realized, we do not capitalize pre-launch inventory costs prior to completion of marketing authorization unless the regulatory review process has progressed to a point that objective and persuasive evidence of regulatory approval is sufficiently probable, and future economic benefit can be asserted. We record such costs to research and development costs, or if used in marketing evaluations reported to selling, general and administrative expense. A number of factors are taken into consideration, based on management's judgment, including the current status in the regulatory approval process, potential impediments to the approval process, anticipated R&D initiatives and risk of technical feasibility, viability of commercialization and marketplace trends.

Prior to receiving an EUA, costs of property and equipment related to scaling up our manufacturing capacity for commercial launch are recorded to research and development expense when the asset does not have an alternative future use.

Research and development activities are central to our business model. We expect that our research and development expenses will continue to increase for the foreseeable future as we initiate clinical trials for our platform, ramp-up our manufacturing and commercialization efforts and continue to discover and develop platforms and assays for other infectious diseases and disease states. There are numerous factors associated with the successful commercialization of any assay we may develop in the future for other diseases or disease states, including future trial design and various regulatory requirements, many of which cannot be determined with accuracy at this time based on our stage of development.

Selling, general and administrative expenses

Selling, general and administrative expenses consist primarily of salaries and other related costs, including stock-based compensation, for personnel in our executive, finance, sales, product management, corporate and business development and administrative functions.



                                       22

--------------------------------------------------------------------------------

Beginning in the first quarter of 2021, we started to incur selling related expenses as part of planning for a commercial launch of our products. Selling, general and administrative expenses also include professional fees for legal, patent, accounting, information technology, auditing, tax and consulting services, travel expenses and facility-related expenses, which include direct depreciation costs and allocated expenses for rent and maintenance of facilities and other operating costs.

We expect that our selling, general and administrative expenses will increase in the future as we increase our headcount to support our continued research and development and potential commercialization and sales of our platform. We also expect to incur increased expenses associated with being a public company, including costs of accounting, audit, legal, regulatory and tax compliance services, director and officer insurance costs, and investor and public relations costs.

Other income (expense)

Other income (expense), net consists primarily of interest income on cash deposits held at financial institutions, gains and losses on holdings invested in money market funds, and unrealized and realized foreign exchange gains and losses.

Grant revenue

Our revenue for the three months ended June 30, 2021 and 2020 relates to the CARB-X and NIH grants and the RADx initiative. During the three months ended June 30, 2021, $0.1 million of revenue was recognized related to our NIH grant. During the three months ended June 30, 2020, $0.3 million, $0.2 million, and $0.3 million of revenue was recognized related the NIH, CARB-X grants, and RADx grants, respectively.

Research and development expenses

Substantially all of our research and development expenses incurred for the three months ended June 30, 2021 were related to the manufacturing scale-up for, and development of our first potential commercial product utilizing the Talis One system, a rapid, point-of-care molecular diagnostic test to detect COVID-19 directly from a patient sample.

Research and development expenses were $54.5 million for the three months ended June 30, 2021, compared to $8.2 million for the three months ended June 30, 2020, an increase of $46.3 million. The increase was primarily due to increases of $23.0 million related to the automation of consumable manufacturing, an increase of $10.6 million in instrument component costs, an increase of $7.1 million relating to Talis One cartridge materials for the COVID-19 assay, including $3.6 million related to the modification of one of the agreements with our suppliers, and an increase of $2.4 million related to professional and personnel related expenses, including increased consulting expenses, stock compensation expenses, and personnel related expenses as we increased full-time and temporary headcount, and an increase of $3.2 million relating to an increase in outside services, allocated facilities and IT costs, supplies, freight and logistics costs.

The ramp up of our manufacturing efforts, which began in the middle of 2020, is expected to be completed by the end of 2021. As of June 30, 2021, we have incurred approximately $100.5 million related to such manufacturing scale-up costs, of which $92.8 million has been incurred related to high capacity production equipment and $7.7 million has been incurred related to our cartridge expenses. During the three months ended June 30, 2021, the Company incurred $23.3 million of these costs. We expect to incur approximately $12.3 million of additional costs in the near term, which we expect to be recognized in research and development expense until we



                                       23

--------------------------------------------------------------------------------

receive emergency use authorization. We submitted our EUA application for the Talis One system and COVID-19 assay cartridges in July 2021. See "Liquidity and capital resources - Future funding requirements" below for additional information.

Selling, general and administrative expenses

Selling, general and administrative expenses were $10.0 million for the three months ended June 30, 2021, compared to $2.7 million for the three months ended June 30, 2020, an increase of $7.3 million. The increase was primarily due to increased personnel related expenses of $6.2 million, including salaries and wages, stock-based compensation expenses and personnel related expenses as we have increased headcount consulting and recruiting expenses in these departments, and an increase of $1.1 million related to increased expenses for insurance, intellectual property, and professional services.

Comparison for the six months ended June 30, 2021 and 2020

During the six months ended June 30, 2021, $7.0 million of revenue was recognized related to the completion of Stage 2 and Stage 3 milestones as part of the RADx grant and $0.1 million of revenue was recorded related to our NIH grant. During the six months ended June 30, 2020, $0.6 million, $0.3 million, and $0.3 million of revenue was recognized related the NIH, CARB-X grants, and RADx grants, respectively.

Research and development expenses

Substantially all of our research and development expenses incurred for the six months ended June 30, 2021 were related to the manufacturing scale-up for, and development of our first potential commercial product utilizing the Talis One system, a rapid, point-of-care molecular diagnostic test to detect COVID-19 directly from a patient sample.

Research and development expenses were $114.7 million for the six months ended June 30, 2021, compared to $13.9 million for the six months ended June 30, 2020, an increase of $100.8 million. The increase was primarily due to increases of $51.5 million related to the automation of consumable manufacturing, an increase of $24.8 million in instrument component costs, an increase of $13.0 million relating to Talis One cartridge materials for the COVID-19 assay, including $3.6 million related to the modification of one of the agreements with our suppliers, and an increase of $5.8 million related to professional and personnel related expenses, including increased consulting expenses, stock compensation expenses, and personnel related expenses as we increased full-time and temporary headcount, and an increase of $5.7 million relating to an increase in outside services, allocated facilities and IT costs, supplies, equipment, freight and logistics costs.

During the six months ended June 30, 2021 we have incurred $51.6 million in expenses related to our manufacturing scale-up activities.

Selling, general and administrative expenses

Selling, general and administrative expenses were $17.3 million for the six months ended June 30, 2021, compared to $4.7 million for the six months ended June 30, 2020, an increase of $12.6 million. The increase was primarily due to increased personnel related expenses of $10.4 million, including salaries and wages, stock-based compensation expenses and personnel related expenses as we have increased headcount, consulting and recruiting expenses in these departments, and an increase of $2.2 million related to increased expenses for insurance, and professional services, and intellectual property.

Liquidity and capital resources

Sources of liquidity

On February 12, 2021, we completed our IPO, pursuant to which we issued and sold 13,800,000 shares of our common stock and an additional 2,070,000 shares pursuant to the exercise in full by the underwriters of their option to purchase additional shares of our common stock, at a public offering price of $16.00 per share. The net proceeds from the IPO were $232.5 million after deducting underwriting discounts and commissions and other offering expenses.

We believe our cash balance as of June 30, 2021 is sufficient for our operations for at least the next 12 months from the date our condensed financial statements are issued based on our existing business plan and our ability to control the timing of significant expense commitments.

Future funding requirements

We do not have any commercial-scale manufacturing facilities and expect to rely on third parties to manufacture the Talis One system and related cartridges. We have entered into, and expect to enter into additional, agreements with contract manufacturers to support our manufacturing scale-up. We will also need engage third-party logistics providers to manage the movement of materials between suppliers and contract manufacturers and for finished goods warehousing. We also intend to invest in additional manufacturing capacity to meet market demand if the Talis One system is approved for marketing. The ramp up of these manufacturing efforts, which began in the middle of 2020, is expected to result in a significant increase in our research and development expenses until regulatory approval of our products is achieved.

We do not yet have any products approved for sale, and we have never generated any revenue from contracts with customers. We do not expect to generate any meaningful revenue unless and until we obtain regulatory approval of and commercialize our Talis One system. Until we can generate a sufficient amount of revenue from the commercialization of Talis One system, if ever, we expect to finance our future cash needs through public or private equity offerings or debt financings.

To date, our primary uses of cash have been to fund operating expenses, primarily research and development expenditures. Cash used to fund operating expenses is impacted by the timing of when we pay these expenses, as reflected in the change in our outstanding accounts payable and accrued expenses. We currently have no other ongoing material financing commitments, such as other lines of credit or guarantees. We have recently increased our spending on automated cartridge manufacturing scale-up and instrument manufacturing, and expect expenses related to manufacturing to increase significantly as we prepare for a potential near-term commercial launch. We expect our expenses to increase in connection with our ongoing activities, particularly as we continue the research and development of, continue or initiate clinical trials of, and seek marketing approval for, our platform. In addition, if we obtain marketing approval for our platform, we expect to incur significant commercialization expenses related to program sales, marketing, manufacturing and distribution to the extent that such sales, marketing and distribution are not the responsibility of any future collaborators. We expect to incur additional costs associated with operating as a public company. Accordingly, we may choose to obtain additional funding in connection with our continuing operations. If we are unable to raise capital when needed or on attractive terms, we would be forced to delay, reduce or eliminate our research and development programs or future commercialization efforts.

Since our inception, we have incurred significant losses and negative cash flows from operations. We have an accumulated deficit of $297.9 million through June 30, 2021. We expect to incur substantial additional losses in the future as we conduct and expand our research and development, manufacturing and commercialization activities. Based on our planned operations, we expect that our unrestricted cash of $313.5 million as of June 30, 2021, will be sufficient to fund our operations for at least 12 months after these financial statements are issued. However, we may need to raise additional capital through equity or debt financing, or potential additional collaboration proceeds prior to achieving commercialization of our products. Our ability to continue as a going concern is dependent upon our ability to successfully secure sources of financing and ultimately achieve profitable operations.

We have based our projections of operating capital requirements on assumptions that may prove to be incorrect and we may use all our available capital resources sooner than we expect. Because of the numerous risks and uncertainties associated with research, development and commercialization of the Talis One system, we are unable to estimate the exact amount of our operating capital requirements. Our future capital requirements will depend on many factors, including:



    •   our ability to receive, and the timing of receipt of, an EUA for our
        COVID-19 test;


    •   the effectiveness and availability of the three vaccines in the U.S. that
        were authorized as of June 2021;


    •   the amount of capital, and related timing of payments, required to build
        sufficient inventory of our Talis One system and test cartridges in
        advance of and during commercial launch;


                                       25

--------------------------------------------------------------------------------




    •   the costs and timing of future commercialization activities, including
        manufacturing, marketing, sales and distribution, for our platform if we
        receive marketing approval;


    •   limitations of, or interruptions in, the quality or quantity of materials
        from our third party suppliers;


    •   our ability to implement an effective manufacturing, marketing and
        commercialization operation;


  • the scope, progress, results and costs of our ongoing and planned operations;


  • the costs associated with expanding our operations;


    •   the number and development requirements of assays for other diseases or
        disease states that we may pursue;


  • intervention, interruptions or recalls by government or regulatory agencies;


  • enhancements and disruptive advances in the diagnostic testing industry;


    •   our estimates and forecasts of the market size addressable by our Talis
        One system;


    •   security breaches, data losses or other disruptions affecting our
        information systems;


    •   the regulatory and political landscape upon the launch of our
        commercialization of the Talis One system;


    •   the revenue, if any, received from commercial sales of our products if
        approved, including additional working capital requirements if we pursue a
        reagent rental model for our Talis One instrument;


  • our ability to establish strategic collaborations; and


    •   the costs and timing of preparing, filing and prosecuting patent
        applications, maintaining and enforcing our intellectual property rights
        and defending any intellectual property-related claims.

Cash flows

The following table summarizes our cash flows for each of the periods presented:





                                                                 Six Months Ended June 30,
                                                                 2021                2020
                                                                      (in thousands)
Cash used in operating activities                            $     (55,895 )     $     (17,535 )
Cash used in investing activities                                   (1,120 )              (337 )
Cash provided by financing activities                              232,757             111,540

Net increase in cash, cash equivalents and restricted cash $ 175,742 $ 93,668






Operating activities

During the six months ended June 30, 2021, cash used in operating activities was $55.9 million, resulting primarily from our net loss of $125.0 million partially offset by an increase in our accrued expenses and accounts payable of $49.4 million and $6.6 million, respectively, a decrease in our prepaid research and development of $9.6 million, and non-cash items of $4.5 million, made up of stock-based compensation of $3.6 million, amortization of our right-of-use assets on operating leases of $0.5 million, and depreciation expense of $0.4 million. The increase in our accrued expenses of $49.4 million was primarily associated with our manufacturing scale-up project. We have increased spending on cartridge manufacturing scale-up and instrument manufacturing as we prepare for a potential commercial launch. These increases were partially offset by an increase in other long-term assets of $1.0 million relating to the long-term deposit held on one of our operating leases.

During the six months ended June 30, 2020, cash used in operating activities was $17.5 million, resulting primarily from our net loss of $17.4 million, increase of prepaid research and development of $3.4 million, a decrease in accrued expenses and other liabilities of $3.1 million, a decrease in unbilled grant receivable of $1.2 million and an increase in long-term assets of $0.3 million. This was offset by an increase in accounts payable of $4.0 million, $1.7 million of non-cash items including stock-based compensation of $1.1 million, depreciation and amortization of $0.4 million and non-cash lease expense of $0.3 million.

Investing activities

During the six months ended June 30, 2021 and 2020, we used $1.1 million and $0.3 million of cash, respectively, for investing activities related to purchases of property and equipment.

Financing activities

During the six months ended June 30, 2021, net cash provided by financing activities was $232.8 million, primarily consisting of $232.6 million of proceeds from the issuance of common stock in our initial public offering and $0.2 million in proceeds from stock option exercises.

During the six months ended June 30, 2020, net cash provided by financing activities was $111.5 million, consisting of proceeds from the issuance of preferred stock.

Contractual obligations and commitments

The following table summarizes our non-cancellable contractual obligations at June 30, 2021, and the effects that such obligations are expected to have on our liquidity and cash flows in future periods:





                                           Payments due by period
                                                  Less than      1 to 3

Operating leases(1)                 $  5,998     $     1,004     $ 4,994
Purchase commitments(2)               64,127          64,127           -

(1) Represents minimum contractual lease payments on our real estate leases in

Menlo Park, California and Chicago, Illinois. During the first quarter of
    2021, we entered into a lease laboratory and office space in Redwood City,
    CA. Because the lease has not commenced, we have excluded the commitment from
    the above analysis as of June 30, 2021. The Redwood City, CA lease will
    extend for an initial term of 10.5 years with a minimum commitment of
    approximately $2.6 million annually with fixed escalations of 3.0% per annum.

(2) Represents firm purchase commitments in the normal course of business of $2.2

million and $61.9 million of Talis One instruments and Talis One cartridges,

respectively.

(3) Represents firm commitments relating to the scale-up of manufacturing

capacity for Talis One cartridges, primarily attributed to investments in

production lines.

Apart from the contracts with payment commitments that we have reflected in the table, we have entered into other contracts in the normal course of business with certain contract manufacturing organizations and other third parties for manufacturing services. Payments due upon cancellation consist only of payments for services provided and expenses incurred, including non-cancelable obligations of our service providers, up to the date of cancellation.

Critical accounting policies and significant judgments and estimates

This discussion and analysis of financial condition and results of operation is based on our unaudited condensed financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of financial statements requires management to make estimates and judgments that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities as of the date of the financial statements and the reported amounts of expenses during the reporting period. On an ongoing basis, management evaluates its estimates and assumptions.

Our critical accounting policies and estimates are discussed in our Annual Report. There have been no material changes to our critical accounting policies and estimates during the six months ended June 30, 2021.

Recently issued accounting pronouncements

A description of recently issued accounting pronouncements that may potentially impact our financial position and results of operations is disclosed in Note 2 to our unaudited condensed financial statements included within Item I of this Quarterly Report.

Emerging growth company status

In April 2012, JOBS Act was enacted. Section 107 of the JOBS Act provides that an emerging growth company may take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act for complying with new or revised accounting standards. Therefore, an emerging growth company can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We have irrevocably elected to avail ourselves of this extended transition period and, as a



                                       27

--------------------------------------------------------------------------------

result, we may adopt new or revised accounting standards on the relevant dates on which adoption of such standards is required for non-public companies instead of the dates required for other public companies.

We may take advantage of these exemptions for up to the last day of the fiscal year ending after the fifth anniversary of our initial public offering or such earlier time that we are no longer an emerging growth company. We would cease to be an emerging growth company on the date that is the earliest of (1) the last day of the fiscal year in which we have total annual gross revenues of $1.07 billion or more; (2) the last day of our fiscal year following the fifth anniversary of the date of our initial public offering; (3) the date on which we have issued more than $1.0 billion in nonconvertible debt during the previous three years; or (4) the date on which we are deemed to be a large accelerated filer under the rules of the SEC.
