Overview



We are a leading cell analysis solutions company advancing the next generation
of cell analysis tools by leveraging novel technical approaches. Our goal is to
become the premier cell analysis company through continued innovation that
facilitates scientific advances in biomedical research and clinical
applications. We believe our core instruments, the Aurora and Northern Lights
systems, are the first full spectrum flow cytometers able to deliver
high-resolution, high-content and high-sensitivity cell analysis by utilizing
the full spectrum of fluorescence signatures from multiple lasers to distinguish
fluorescent tags on single cells ("Full Spectrum Profiling" or "FSP"). Our novel
approach harnesses the power of information within the entire spectrum of a
fluorescent signal to achieve a higher level of multiplexing with exquisite
sensitivity. Our patented FSP technology optimizes sensitivity and accuracy
through its novel optical and electronic designs that utilize an innovative
method of light detection and distribution. Our FSP platform includes
instruments, reagents, software and services to provide a comprehensive and
integrated suite of solutions for our customers. Since our first U.S. commercial
launch in mid-2017, we have sold and deployed over 1,000 instruments-primarily
comprised of our Aurora and Northern Lights systems-to over 840 customers around
the world, including the largest pharmaceutical companies, over 150 biopharma
companies, leading academic research centers, and clinical research
organizations ("CROs"). In June 2021, we began shipping the Aurora cell sorter
("Aurora CS"), which uses our FSP technology to further broaden our potential
applications across cell analysis.

We manufacture our instruments in our facilities in Fremont, California and in
Wuxi, China. We have designed our operating model to be capital efficient and to
scale efficiently as our product volumes grow.

Our total revenue was $128.0 million and $92.8 million in the year ended December 31, 2021 and 2020, respectively. The increase was primarily due to sales of our Aurora, Aurora CS, and Northern Lights systems.



To date, we have adopted a direct sales model in North America, Europe and
China, and sell our products through third-party distributors in certain
countries in Europe, Latin America, the Middle East, Africa, and the
Asia-Pacific region. Revenue from direct sales represented 86% and 83% of total
revenue for the year ended December 31, 2021 and 2020, respectively, and revenue
from distributors represented 14% and 17% of total revenue for the year ended
December 31, 2021 and 2020, respectively.

We focus a substantial portion of our resources on developing new products and
solutions to meet our customers' needs. Our research and development efforts
focus on developing new and complementary instruments, reagents and reagent
kits, and continued operating software development. We incurred research and
development expenses of $24.4 million and $13.7 million for the year ended
December 31, 2021 and 2020, respectively. We intend to continue to make
significant investments in research and development in the future.

We expect to continue to invest in our commercial infrastructure through hiring
additional employees with strong scientific and technical backgrounds to support
growth in sales of our Aurora, Northern Lights and Aurora CS systems, as well as
our planned expansion of reagents offerings and panel design capabilities. We
also plan to continue to invest in sales, marketing and business development
across the globe to drive commercialization of our products. We incurred sales
and marketing expenses of $24.7 million and $15.0 million for the year ended
December 31, 2021 and 2020, respectively.

Since our inception in 2014, we have financed our operations primarily through sales of our securities and revenue from the sale of our products and services.



Our net income was $3.0 million and $19.4 million for the year ended December
31, 2021 and 2020, respectively. The change for the year ended December 31, 2021
compared to the year ended December 31, 2020 resulted primarily from expenses
driven by an increase in headcount and salaries, expenses related to our IPO,
and efforts in research and development and marketing initiatives. Net

                                       53
--------------------------------------------------------------------------------


income of $3.0 million as disclosed in this Annual Report on Form 10-K differs
from net income of $4.4 million previously reported in our earnings press
release issued on February 23, 2022 due to a $1.4 million tax adjustment made
prior to the filing of this Form 10-K and omitted from the net income amount
included in our earnings press release.

We expect our expenses will increase substantially in connection with our on-going activities, as we:

attract, hire and retain qualified personnel;

invest in processes, commercial infrastructure and supporting functions to scale our business and introduce new products and services;

support our research and development efforts;

continue to expand geographically;

protect and defend our intellectual property; and

make strategic investments in complementary businesses, services, products or technologies.



On November 2, 2021, we completed the acquisition of the reagents business of
Tonbo Biotechnologies Corporation as detailed in Note 8, Acquisition, to
consolidated financial statements included elsewhere in this Annual Report on
Form 10-K. The acquired assets include a portfolio of life science research
reagents related to cell preparation, flow cytometry, molecular
immunology/polymerase chain reaction and cell culture covering application areas
across immunology, apoptosis and immunoprofiling.

Key factors affecting our results of operations and future performance

We believe that our financial performance has been, and in the foreseeable future will continue to be, primarily driven by multiple factors as described below, each of which presents growth opportunities for our business. These factors also pose important challenges that we must successfully address to sustain our growth and improve our results of operations. Our ability to successfully address these challenges is subject to various risk and uncertainties, including those described under the heading "Risk Factors" included elsewhere in this Annual Report on Form 10-K.

Global customer adoption



Our financial performance has largely been driven by our ability to increase the
adoption of our FSP platform, a key factor on which our future success depends.
We plan to drive global customer adoption through business development efforts,
direct sales and marketing and third-party distributions. We are investing in
our direct sales organization and commercial support functions and developing
third-party distributor relationships to support global expansion and drive
revenue growth. As part of this effort, we increased our direct sales force by
55% in the year ended December 31, 2021 compared to the year ended December 31,
2020. We intend to continue increasing our workforce in line with our growth.

Recurring revenues



We believe our expanding installed base of instruments to new and existing
customers will provide us with greater leverage to drive pull-through for
reagent and service revenue, which are recurring by nature. Furthermore, as we
develop and identify new applications and products, we expect to further
increase pull-through across our installed base. We expect recurring revenue on
an absolute basis to increase and become an increasingly important contributor
to our revenue as our installed base expands.

Revenue mix and gross margin



Our revenue is primarily derived from sales of our instruments and services with
our instruments recognizing higher gross margins than our services. Although we
expect sales of our instruments to continue to represent the largest percentage
of our revenue in the future, we expect reagent sales to increase as a
percentage of our total revenue and our gross margins to experience a
corresponding improvement as we grow our installed base and increase our focus
on commercializing reagents. We also expect a higher gross margin on our
instruments as we increase manufacturing efficiency, instrument reliability and
training for personnel using our instruments, which we expect to lead to a
reduction in warranty claims. Our sales in certain regions, particularly outside
of the United States, are realized through third-party distribution partners
that typically receive discounted prices, thus resulting in lower gross margins
than those recognized by our direct sales organization. Furthermore, our gross
margins and instrument selling prices may fluctuate in the future as we continue
to grow our volume of third-party distribution partners in geographies outside
of the United States, introduce new products and reduce our production costs as
a result of variability in the timing of new product introductions.

In the near term, we expect the continued optimization of our manufacturing processes related to our instruments and the expansion of product manufacturing distribution facilities to have the greatest impact on our gross margin. In addition to the impact of competing


                                       54
--------------------------------------------------------------------------------

products entering the market, the future gross margin profiles of our instruments, services and reagents will depend on the outcome of any royalties we are required to pay and the royalty rates and products to which such royalties apply.

Expansion into new markets



We focus our research and development efforts on the greatest value-additive FSP
products to meet the growing and unmet needs of the research and clinical
markets. We work closely with researchers and clinicians to optimize and
implement new panels and applications to meet their specific needs. We also gain
valuable insight on potential new products, new applications and enhancements to
existing products, as well as biomarker combinations that would be beneficial in
different fields, through collaborations with our customers, academic
laboratories, KOLs and industry partners. We plan to continue to invest in new
product development and enhancements to support our expansion into new markets.

Our Northern Lights system obtained clinical certification in China in 2019 and
received CE Marking under the European Union In Vitro Diagnostic Medical Devices
Directive in September 2020. With these achievements, our Northern Lights system
is available for clinical diagnostic use in hospitals, laboratories, and clinics
in China and the European Union.

Key business metrics



We regularly review the following key business metrics to evaluate our business,
measure our performance, identify trends affecting our business, formulate
financial projections and make strategic decisions. We believe that the
following metrics are representative of our current business; however, we
anticipate these will change or may be substituted for additional or different
metrics as our business grows.

COVID-19

The global COVID-19 pandemic continues to evolve and we intend to continue to
monitor it closely. In response to the COVID-19 pandemic and various resulting
government directives, we took proactive measures to protect the health and
safety of our employees, contractors, customers and visiting vendors and
suppliers, including implementing social distancing and other protective
measures, restricting business travel and limiting access to our facilities to
vendors, suppliers and partners who are critical to our business operations. We
communicate regularly with our suppliers so that our supply chain remains
intact, and we have not experienced any material supply issues. We also
developed, and continue to develop, remote learning capabilities to help our
customers and partners operate and reduce the number of required
customer/partner on-site visits for our field application scientists and field
support engineers to comply with travel restrictions and country-specific
quarantine requirements. While the COVID-19 pandemic has not had a material
adverse effect on our business, results of operations or the operation of
financial reporting systems, internal control over financial reporting and
disclosure controls and procedures, given the considerable uncertainty around
the duration and extent of the pandemic, the related financial and operational
impact cannot be reasonably estimated. We continue to monitor the implications
of the COVID-19 pandemic on our business, as well as our customers' and
suppliers' business. Potential impacts of the COVID-19 pandemic, some of which
we have already experienced, include those described throughout the "Risk
Factors" section, including "A pandemic, epidemic

                                       55
--------------------------------------------------------------------------------


or outbreak of an infectious disease in the United States or worldwide could
adversely affect our business. The COVID-19 pandemic has had and could continue
to have an adverse impact on our business, operations, and the markets and
communities in which we, our partners, and customers operate."

Components of our results of operations

Total revenue, net

We currently generate our total revenue, net from product revenue and service revenue.



Product. Our product revenue primarily consists of sales of our instruments,
including the Aurora, Northern Lights and Aurora CS systems, instrument
accessories, such as loaders and, to a lesser extent, consumables, such as
reagents. We offer multiple versions of our Aurora and Northern Lights systems
with different price points based on the number of lasers integrated in the
systems. We also derive revenue from sales of our conventional flow cytometry
system, which is available for sale in China. We recognize product revenue when
control of the instrument is transferred to the customer.

Service. Our service revenue primarily consists of post-warranty service contracts, installations and repairs which are recognized over time. Post-warranty service contracts are recognized ratably over the term of the contract and installations and repair services are recognized as they are delivered to the customer.



We expect our revenue to increase in absolute dollars as we expand our sales
organization and sales territories, broaden our customer base, and expand
awareness of our products with new and existing customers. Our revenue was
$128.0 million and $92.8 million for the year ended December 31, 2021 and 2020,
respectively.

Total cost of sales, gross profit and gross margin

Our total cost of sales is comprised of product cost of sales and service cost of sales.

Product. Cost of sales associated with our products primarily consist of manufacturing-related costs incurred in the production process, inventory write-downs, warranty costs, third party royalty costs, personnel and related costs, costs of component materials, overhead, packaging and delivery and depreciation expense.

Service. Cost of sales associated with our services primarily consists of personnel and related costs, expenses related to product replacements, product updates and qualification validation of our products and depreciation expense.

We expect our total cost of sales to increase in absolute dollars in future periods, corresponding to our anticipated growth in revenue and employee headcount to support our manufacturing, operations, field service team and support organizations.



Gross profit is calculated as revenue less total cost of sales. Gross margin is
gross profit expressed as a percentage of revenue. Our gross profit in future
periods will depend on a variety of factors, including market conditions that
may impact our pricing, sales mix changes among our instruments and service
agreements, product mix changes between established products and new products,
excess and obsolete inventories, our cost structure for manufacturing operations
relative to volume and product warranty obligations.

Operating expenses

Our operating expenses are primarily comprised of research and development, sales and marketing, and general and administrative expenses, depreciation and amortization, and related overhead.

Research and development. Our research and development expenses primarily consist of salaries, benefits, stock-based compensation costs for employees in our research and development department, independent contractor costs, laboratory supplies, equipment maintenance and materials expenses.



We plan to continue to invest in our research and development efforts, including
hiring additional employees to enhance existing products and develop new
products. We expect research and development expense will increase in absolute
dollars in future periods and vary from period to period as a percentage of
revenue due to our continuing investment in product development.

Sales and marketing. Our sales and marketing expenses consist primarily of
salaries, benefits, and stock-based compensation costs for employees in our
sales and marketing department, sales commissions, marketing material costs,
travel expenses and costs related to trade shows, trainings and various
workshops. We expect our sales and marketing expense to increase in absolute
dollars as we expand our commercial sales, marketing, and business development
teams, increase our presence globally and increase marketing activities to drive
awareness and adoption of our platform. While these expenses may vary from
period to period as a percentage of revenue, we

                                       56
--------------------------------------------------------------------------------


expect these expenses to increase as a percentage of sales in the short-term as
we continue to grow our commercial organization to support anticipated growth of
the business.

General and administrative. Our general and administrative expenses primarily
consist of salaries, benefits, and stock-based compensation costs for employees
in our executive, accounting and finance, legal and human resource functions, as
well as professional services fees, such as consulting, audit, tax, legal,
general corporate costs and allocated overhead expenses. We expect our operating
expenses to increase as a public company. In particular, we expect our
accounting, legal, personnel-related expenses and directors' and officers'
insurance costs reported within general and administrative expense to increase
as we establish more comprehensive compliance and governance functions, maintain
IT costs, review internal controls over financial reporting in accordance with
the Sarbanes-Oxley Act and prepare and distribute periodic reports as required
by the rules and regulations of the SEC. As a result, our historical results of
operations may not be indicative of our results of operations in future periods.

We expect these expenses to vary from period to period as a percentage of revenue.

Other income (expense), net

Interest expense. Interest expense consists primarily of accretion of the present value of the litigation settlement liability. See Note 10 to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K for further details regarding the settlement.



Interest income. Our interest income consists primarily of interest earned on
our cash and cash equivalents which are invested in cash deposits and in money
market funds.

Other income (expense), net. Our other income (expense), net consists primarily of foreign exchange gains and losses.

Income taxes



Our provision for (benefit from) income taxes consists primarily of provision
for federal taxes, local taxes and state minimum taxes in the United States as
well as foreign taxes. As we plan to expand the scale and scope of our
international business activities, any changes in the United States and foreign
taxation of such activities may increase our overall provision for income taxes
in the future.

Total revenue, net increased by $35.1 million, or 38%, for the year ended
December 31, 2021 as compared to the year ended December 31, 2020. The increase
in revenue was primarily driven by an increase in product revenue due to higher
unit sales of our Aurora and Northern Lights systems, sales of our Aurora CS
system, which commercially launched in June 2021, and an increase in the average
blended selling price due to product mix.

Product revenue increased by $34.2 million, or 40%, to $119.5 million, for the
year ended December 31, 2021 as compared to the year ended December 31, 2020.
The increase was primarily driven by an increase in our instrument sales due to
higher unit sales of our Aurora and Northern Lights systems, sales of our Aurora
CS system, which commercially launched in June 2021, and an increase in the
average blended selling price due to product mix.

Service revenue increased by $0.9 million, or 12%, to $8.4 million, for the year
ended December 31, 2021 as compared to the year ended December 31, 2020. The
increase in service revenue was driven by more instruments coming off warranty,
offset by reduced service contract revenue associated with non-Cytek
instruments. While we have historically performed maintenance services and
support functions for non-Cytek instruments, we ceased sales of service
contracts for non-Cytek instruments as of January 1, 2021 while continuing to
honor pre-existing multi-year service contracts. We perform on-demand
professional services to support non-Cytek

                                       58
--------------------------------------------------------------------------------


instruments provided that resources are available. As a result of our decision
to no longer service non-Cytek instruments, revenue associated with service
contracts for non-Cytek instruments decreased in the year ended December 31,
2021. Our strategy was to shift resources in anticipation of the increasing
demand for our Aurora and Northern Lights instruments, and to allow us to fully
support our instruments when they come out of warranty.

Gross margin                                   62 %            56 %




Total cost of sales increased by $7.7 million, or 19%, for the year ended
December 31, 2021 as compared to the year ended December 31, 2020. This is
primarily due to more instruments shipped and increased service and
manufacturing headcount and associated personnel cost, including $1.3 million
stock-based compensation; offset by lower inventory write-downs as a result of
operational efficiencies.

Gross profit margin was 62% and 56% as a percent of total revenue for the year
ended December 31, 2021 and 2020, respectively. The increase is primarily due to
an increase of instruments delivered to customers, an increase in the average
blended selling price due to product mix, and lower inventory write-downs for
the year ended December 31, 2021.

While we have seen an increase in total gross profit margin, the gross profit
margin of our service revenue has decreased from (17)% in the year ended
December 31, 2020, to (36)% in the year ended December 31, 2021. This was due to
an increase in headcount and personnel-related expenses. The decrease was also
driven by reduced service contract revenue on non-Cytek instruments consistent
with our expectations after not renewing these contracts.

Research and development expenses were $24.4 million for the year ended December
31, 2021 as compared to $13.7 million for the year ended December 31, 2020. The
increase of $10.7 million in research and development expenses was primarily due
to an increase in headcount and personnel-related expenses, including
stock-based compensation of $1.8 million.

We expect our research and development expense to increase in absolute dollars as we continue to develop new products and enhance existing instruments and technologies.

Sales and marketing expenses were $24.7 million for the year ended December 31,
2021 as compared to $15.0 million for the year ended December 31, 2020. The
increase of $9.7 million in sales and marketing expenses was primarily due to an
increase in headcount, commissions, and personnel-related expenses of $7.0
million, including stock-based compensation of $1.2 million. There was also an
increase in advertising and marketing activities of $0.8 million.

We expect our sales and marketing expenses to increase in absolute dollars as we hire additional sales and marketing personnel, expand our sales support infrastructure and invest in our brand and product awareness to further penetrate the United States and the international markets.

General and administrative expenses were $20.8 million for the year ended
December 31, 2021 as compared to $9.4 million for the year ended December 31,
2020. The increase of $11.5 million in general and administrative expenses was
primarily due to an increase in general corporate personnel-related costs,
professional fees relating to our IPO, and infrastructure services to support
the growth of our overall operations. The increase in personnel-related costs
was primarily due to increased headcount and stock-based compensation of $1.7
million.

We expect to continue to incur additional general and administrative expenses as
a result of operating as a public company, including expenses related to
compliance with the rules and regulations of the SEC and the Nasdaq Stock
Market, additional insurance costs, investor relations activities and other
administrative and professional services. As a result, we expect general and
administrative expenses to increase in absolute dollars in future periods.

Interest income was $49,000 for the year ended December 31, 2021 as compared to
$110,000 for the year ended December 31, 2020. The decrease of $61,000 in
interest income was the result of lower interest earned on our cash and
short-term deposits due to a decline in interest rates as compared to year ended
December 31, 2020.

in the second quarter of fiscal 2020 and an increase in income tax from higher
earnings in the year ended December 31, 2021.

Liquidity and capital resources

Overview



To date, our primary sources of capital have been through sales of our
securities and revenue from the sale of our products and services. As of
December 31, 2021 and December 31, 2020, we had approximately $364.6 million and
$165.2 million, respectively, in cash and cash equivalents, which were primarily
held in U.S. short-term bank deposit accounts and money market funds.

Funding requirements



We anticipate continuing to expend significant amounts of cash in the
foreseeable future as we continue to invest in research and development of our
product offerings, commercialization of new products and services, and expansion
into new markets. Our future capital requirements will depend on many factors
including our revenue, research and development efforts, the new and continued
impacts of the COVID-19 pandemic, the timing and extent of additional capital
expenditures to invest in existing and new facilities, as well as our
manufacturing operations, the expansion of sales and marketing and the
introduction of new products. We have entered into, and may in the future enter
into, arrangements to acquire or invest in businesses, services and
technologies, and any such acquisitions or investments could significantly
increase our capital needs.

We currently anticipate making additional capital expenditures during the next 12 months, which is expected to primarily include equipment to be used for manufacturing and investment in research and development, as well as spend associated with the expansion of our facilities in Wuxi, China.



Based on our current business plan, we believe our existing cash and cash
equivalents and anticipated cash flows from operations will be sufficient to
meet our working capital and capital expenditure needs for at least the next 12
months from the date of this Annual Report on Form 10-K.

Sources of liquidity



We have financed our operations primarily through sales of our securities. In
July 2021, we completed our IPO, which resulted in net proceeds to us of
approximately $215.7 million. We have also benefited from operating cash flows
from the sale of our products and services.

On May 7, 2020, we received loan proceeds in the amount of approximately $4.1
million under the PPP. The PPP, established as part of the CARES Act, provides
for loans to qualifying businesses for amounts up to 2.5 times of the average
monthly payroll expenses of the qualifying business. On May 4, 2021, we fully
repaid the PPP loan.

Operating activities

Net cash provided by operating activities for the year ended December 31, 2021
was $4.6 million, including net income of $3.0 million. We also incurred
non-cash stock-based compensation expense, interest expenses for accretion of
the legal settlement liabilities, and depreciation and amortization of $6.6
million, $1.7 million, and $1.2 million, respectively. Usage of cash included an
increase of trade accounts receivable of $12.4 million due to an increase in
sales, an increase in inventories of $7.1 million, an increase in prepaid
expenses and other assets of $6.3 million, and a decrease in the legal
settlement liability of $3.7 million due to payment to BD of $6.0 million, which
is offset by increased royalty accrual. This was partially offset by an increase
in deferred revenue of $10.0 million and an increase in accrued expenses and
other liabilities of $11.0 million.

Net cash provided by operating activities for the year ended December 31, 2020
was $15.2 million, consisting primarily of net income of $19.4 million, an
increase in accrued expenses and other liabilities of $8.2 million directly
attributable to an increase in headcount and the corresponding personnel-related
costs, and an increase in inventories of $5.7 million to accommodate increase in
sales volume.

Investing activities

Net cash used in investing activities during the year ended December 31, 2021
was $21.0 million driven by our acquisition of Tonbo's reagents business for
$17.0 million, an increase in purchases of property and equipment of $4.4
million partially offset by the payment for the additional investment in Cytek
Japan, net of cash acquired of $371,000. See Note 17 to our consolidated
financial statements included elsewhere in this Annual Report on Form 10-K.

Net cash used in investing activities during the year ended December 31, 2020
was $1.5 million primarily driven by an increase in capital expenditures for
laboratory equipment of $1.1 million and an increase in leasehold improvements
of $344,000.

Financing activities

Net cash provided by financing activities during the year ended December 31, 2021 was $213.6 million primarily driven by our IPO, which resulted in net proceeds to us of approximately $215.7 million.



Net cash provided by financing activities during the year ended December 31,
2020 was $122.6 million primarily driven by the issuance of our Series D
redeemable convertible preferred stock in October 2020 for net proceeds of
$119.7 million, net proceeds from the PPP loan of $2.8 million and $169,000 from
the issuance of common stock upon option exercises.

Contractual Obligations and Commitments



During the year ended December 31, 2021, there were no material changes to our
contractual obligations and commitments from those described under "Management's
Discussion and Analysis of Financial Condition" which is contained in our final
prospectus dated July 22, 2021 and filed with the SEC on July 23, 2021 pursuant
to Rule 424(b)(4) under the Securities Act in connection with our IPO.

Off-balance sheet arrangements



We did not have during the periods presented, and we do not currently have, any
off-balance sheet financing arrangements or any relationships with
unconsolidated entities or financial partnerships, including entities sometimes
referred to as structured finance or special purpose entities, that were
established for the purpose of facilitating off-balance sheet arrangements or
other contractually narrow or limited purposes.

Critical accounting policies, significant judgments and use of estimates



We have prepared our consolidated financial statements in accordance with U.S.
GAAP. Our preparation of these consolidated financial statements requires us to
make estimates, assumptions and judgments that affect the reported amounts of
assets, liabilities, revenue, expenses, and related disclosures. We evaluate our
estimates and judgments on an ongoing basis. We based our estimates on our
historical experience and on various other factors that we believe are
reasonable under the circumstances, the results of which form the basis for
making judgments about the carrying value of assets and liabilities that are not
readily apparent from other sources. The economic uncertainty in the current
environment caused by the COVID-19 pandemic could limit our ability to
accurately make and evaluate our estimates and judgments.

Actual results could therefore differ materially from these estimates under
different assumptions or conditions. We believe that the accounting policies
discussed below are critical to understanding our historical and future
performance, as these policies relate to the more significant areas involving
management's judgments and estimates.

While our significant accounting policies are described in Note 2 to our
consolidated financial statements included elsewhere in this Annual Report on
Form 10-K, we believe that the following accounting policies are the most
critical to understanding and evaluating our reported consolidated financial
results.


Revenue recognition

Our product revenue primarily consists of sale of our Aurora, Aurora CS and
Northern Lights systems, instrument accessories, such as loaders and, to a
lesser extent, consumables such as reagents. We offer multiple versions of our
Aurora and Northern Lights systems with different price points based on the
number of lasers integrated in the systems. We also derive revenue from sales of
our conventional flow cytometry system, which is available for sale in China. We
recognize product revenue when control of the instrument is transferred to the
customer.

Our service revenue consists of post-warranty service contracts, preventative
maintenance plans, repairs, installation and quality check, customer training
and other specialized product support services. We recognize service contract
revenue ratably over the term of the contract and other service obligations as
they are performed. Revenue is recognized when control of promised goods or
services is transferred to a customer in an amount that reflects the
consideration to which the entity expects to be entitled in exchange for those
goods or services. To determine revenue recognition for its arrangements with
customers, we perform the following five steps: (i) identify the contract(s)
with a customer; (ii) identify the performance obligations in the contract;
(iii) determine the transaction price; (iv) allocate the transaction price to
the performance obligations in the contract; and (v) recognize revenue when (or
as) the entity satisfies a performance obligation.

A performance obligation is a promise in a contract to transfer a distinct good
or service to the customer and is defined as the unit of account for revenue
recognition under the contract with customers guidance. Performance obligations
are considered distinct if they are both capable of being distinct, and distinct
within the context of the contract. The Company identified the following
performance obligations in the contracts: product sales of instrument systems,
installation on instrument systems, delivery of instrument accessories such as
loaders, consumables, reagents, extended service contracts and professional
services revenue for post-warranty service contracts, preventative maintenance
plans, repairs, installations, training, time and material services and other
specialized support services. A good or service is distinct when the customer
can benefit from the good or service either on its own or together with other
resources that are readily available from third parties or from the Company, and
is distinct in the context of the contract, where the transfer of the good or
service is separately identifiable from other promises in the contract.

Payments from customers are in arrears. For arrangements where the anticipated
period between timing of transfer of services and the timing of payment is one
year or less, we have elected to not assess whether a significant financing
component exists. For arrangements with terms greater than one year, payments
are received up-front and are for reasons other than financing. Revenue is
recognized only to the extent that it is probable that a significant reversal of
the cumulative amount recognized will not occur in future periods.

Certain of our sales contracts involve the delivery or performance of multiple
products and services within contractually binding arrangements. Significant
judgment is sometimes required to determine the appropriate accounting for such
arrangements, including whether the deliverables specified in a contract with
multiple promises should be treated as separate performance obligations for
revenue recognition purposes and, if so, how the related sales price should be
allocated among the performance obligations, when to recognize revenue for each
performance obligation, and the period over which revenue should be recognized.
For most of our performance obligations, we have established the stand-alone
selling prices ("SSP") as a range rather than a single value, based on
standalone sales of products. We allocate revenue to the performance obligations
based on their relative standalone selling prices SSP.

                                       63
--------------------------------------------------------------------------------


Taxes, such as sales, value-add and other taxes, collected from customers
concurrent with revenue generating activities and remitted to governmental
authorities are not included in revenue. Shipping and handling costs associated
with outbound freight are accounted for as a fulfillment cost and are included
in cost of sales.

The following describes the nature of our primary types of revenue and the revenue recognition policies and significant payment terms as they pertain to the types of transactions we enter into with our customers.

Product revenue




Our standard arrangement for sales to end users is generally a purchase order or
an executed contract. Product revenue is recognized upon transfer of control of
the product to the customer, which, for us, generally occurs at a point in time
depending on the shipping terms. Payment terms are generally 30 to 90 days from
the date of invoicing.

Our distributor arrangements with our customers include a purchase order. The
purchase order is governed by terms and conditions of the distributor
agreements. Revenue is recognized upon transfer of control of the products to
the distributor, which for us, occurs at a point in time depending on the
shipping terms.


Service revenue


Our services are primarily a mix of service contracts, installation services,
and time and material-based repair and support. We recognize revenue from the
sale of service contracts over the respective period, while revenue on product
support is recognized as the services are performed. Service contracts are
typically between one and three years. Payment terms are generally 30 days from
the date of invoicing. Installation revenue is recognized upon completion of the
installation, which, for us, occurs at a point in time.

Contract assets and contract liabilities




Contract assets are recorded when the amount of revenue recognized exceeds the
amount invoiced to the customer and the right to payment is not solely subject
to the passage of time. As of December 31, 2021 and 2020, we had immaterial
amounts of contract assets included within prepaid expenses and other current
assets on the consolidated balance sheets.


Contract liabilities consist of fees invoiced or paid by our customers for which
the associated services have not been performed and revenue has not been
recognized based on our revenue recognition criteria described above. Such
amounts are reported as deferred revenue for service and customer deposits for
instruments on the consolidated balance sheets. Deferred revenue that is
expected to be recognized during the following 12 months is recorded as a
current liability and the remaining portion is recorded as noncurrent.

Assurance-type product warranties




We provide a one-year assurance-type warranty that is included with the sale of
our instruments. At the time revenue is recognized for the products, we
establish an accrual for estimated warranty expense based on historical data and
trends of product reliability and costs of repairing and replacing defective
products. We exercise judgment in estimating the expected product warranty
costs, using data such as the historical repair costs. While we believe that
historical experience provides a reliable basis for estimating such warranty
cost, unforeseen quality issues or component failure rates could result in
future costs in excess of such estimates, or alternatively, improved quality and
reliability in our products could result in actual expenses that are below those
currently estimated.


Goodwill and intangible assets




In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other:
Simplifying the Test for Goodwill Impairment, to simplify the subsequent
measurement of goodwill by eliminating Step 2 from the goodwill impairment test.
We adopted this guidance during the year ended December 31, 2019, and the
adoption did not have a material impact on the consolidated financial
statements.


We recognize goodwill in accounting for business combinations based on the
amount by which the total consideration transferred, exceeds the fair value of
identifiable assets acquired and liabilities assumed. Identifiable intangible
assets other than goodwill are primarily comprised of patents and trademarks
which amortize on a straight-line basis over an assigned useful life based on

management's estimate of the period the asset is expected to contribute to future cash flows.




We assess our goodwill and indefinite-lived intangible assets for impairment at
least annually in the fourth quarter, or more frequently if factors indicate
impairment may exist. Our qualitative goodwill impairment analysis consists of
assessing whether any events or circumstances listed in ASC 350-20-35-3A
("triggering events") existed or occurred in the year under review to the date
of the financial statements. The qualitative analysis assesses macroeconomic
conditions, market, and industry considerations, change in cost factors, overall
company financial performance, and any events affecting the reporting unit.
Based on the qualitative analysis results, we determined that it is more likely
than not that the fair values of the reporting unit exceed the carrying value
and that no triggering events were noted that would require a quantitative
impairment assessment in the fiscal year.


Stock-based compensation




We maintain an equity incentive compensation plan under which incentive stock
options and nonqualified stock options to purchase common stock, and restricted
stock units for common stock, are granted primarily to employees and
non-employee consultants.


Stock-based compensation cost is measured at the grant date based on the fair
value of the award and is recognized as expense over the vesting period. The
fair value of stock options is estimated using the Black- Scholes option pricing
model. We record forfeitures as they occur.


The Black-Scholes model considers several variables and assumptions in
estimating the fair value of stock- based awards. These variables include the
per share fair value of the underlying common stock, exercise price, expected
term, risk-free interest rate, expected annual dividend yield and expected stock
price volatility over the expected term. For all stock options granted, we
calculated the expected term using the simplified method for standard stock
option awards. After our IPO, the fair value of our common stock is determined
by the closing price of our common stock on the date of grant as reported on the
Nasdaq Global Select Market. The risk-free interest rate is based on the yield
available on U.S. Treasury zero-coupon issues similar in duration to the
expected term of the equity-settled award.


The following table summarizes the weighted-average assumptions used in
estimating the fair value of stock options granted during each of the periods
presented:

                              Year ended December 31,
                              2021              2020
Expected term (in years)          6.05              5.96
Expected volatility                 90 %              83 %
Risk-free interest rate              1 %               1 %
Dividend yield                       -                 -





Expected volatility-Expected volatility is estimated by studying the volatility
of selected industry peers deemed to be comparable to our business corresponding
to the expected term of the awards.


Expected term-Expected term represents the period that our stock-based awards are expected to be outstanding and is determined using the simplified method.

Risk-free interest rate-The risk-free interest rate is based on the U.S. Treasury zero-coupon issued in effect at the time of grant for periods corresponding with the expected term of the option.

Dividend yield- The expected dividend yield is zero as we have never declared or paid cash dividends and have no current plans to do so in the foreseeable future.

Common stock valuation




There was no public market for our common stock prior to our IPO. As such, the
estimated fair value of our common stock was determined at each grant date by
our board of directors, with input from management, based on the information
known to us on the grant date and upon review of any recent events and their
potential impact on the estimated per share fair value of our common stock. As
part of these fair value determinations, our Board of Directors obtained and
considered valuation reports prepared by third-party valuation firms in
accordance with the guidance outlined in the American Institute of Certified
Public Accountants Technical Practice Aid, Valuation of Privately-Held-Company
Equity Securities Issued as Compensation.

In contemplation of an IPO, we began using a hybrid approach in determining the
fair value of our common stock that includes a probability-weighted expected
return method, or PWERM, and an option pricing method, or OPM. Under a PWERM,
the fair market value of the common stock is estimated based upon an analysis of
future values for the enterprise assuming various future outcomes. Within one of
those potential outcomes, we utilized the OPM. The OPM treats the rights of the
holders of redeemable convertible preferred stock and common stock as equivalent
to that of call options on any value of the enterprise above certain break
points of value based upon the liquidation preferences of the holders of
redeemable convertible preferred stock, as well as their rights to participation
and conversion. Based on the timing and nature of an assumed liquidity event in
each scenario, a discount for lack of marketability either was or was not
applied to each scenario, as appropriate. We then probability-weighted the value
of each expected outcome to arrive at an estimate of fair value per share of
common stock.

In addition to considering the results of these third-party valuation reports,
our board of directors used assumptions based on various objective and
subjective factors, combined with management judgment, to determine the fair
value of our common stock as of each grant date, including:


the prices at which we sold shares of redeemable convertible preferred stock and the superior rights and preferences of the redeemable convertible preferred stock relative to our common stock at the time of each grant;

external market conditions affecting the life sciences research and development industry and trends within the industry;

our stage of development and business strategy;

our financial condition and operating results, including our levels of available capital resources, and forecasted results;




•
developments in our business;


•

the progress of our research and development efforts;

equity market conditions affecting comparable public companies; and

general United States market conditions and the lack of marketability of our common stock.




Application of these approaches involves the use of estimates, judgment and
assumptions that are subjective, such as those regarding our expected future
revenue, expenses and future cash flows, discount rates, market multiples, the
selection of comparable companies and the probability of possible future events.
Changes in any or all of these estimates and assumptions or the relationships
between those assumptions impact our valuations as of each valuation date and
may have a material impact on the valuation of our common stock.

Litigation settlement liability



We are not currently involved in legal proceedings as December 31, 2021. In case
we will be involved in legal proceedings, we are required to assess the
probability of loss and amount of such loss, if any, in preparing our
consolidated financial statements. We evaluate the likelihood of a potential
loss from legal proceedings to which we are a party. We record a liability for
such claims when a loss is deemed probable, and the amount can be reasonably
estimated. Significant judgment may be required in the determination of both
probability and whether an exposure is reasonably estimable. Our judgments are
subjective based on the status of the legal proceedings, the merits of our
defenses and consultation with in-house and outside legal counsel. As additional
information becomes

                                       66
--------------------------------------------------------------------------------


available, we reassess the potential liability related to pending claims and may
revise our estimates. Due to the inherent uncertainties of the legal processes
in the multiple jurisdictions in which we operate, our judgments may be
materially different than the actual outcomes, which could have material adverse
effects on our business, financial conditions, and results of operations.

Recently adopted accounting pronouncements



See Note 2 to our consolidated financial statements included elsewhere in this
Annual Report on Form 10-K for a description of recent accounting pronouncements
applicable to our financial statements.

Emerging growth company and smaller reporting company status



In April 2012, the Jumpstart Our Business Startups Act of 2012 (the "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 result, we will not adopt new or
revised accounting standards on the relevant dates on which adoption of such
standards is required for other public companies. In addition, as an emerging
growth company, we may take advantage of certain reduced disclosure and other
requirements that are otherwise applicable generally to public companies.

We may take advantage of these exemptions until 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 (i) the last day of the fiscal year
following the fifth anniversary of the date of the completion of our IPO; (ii)
the last day of the fiscal year in which our total annual gross revenue is equal
to or more than $1.07 billion; (iii) the date on which we have issued more than
$1.0 billion in nonconvertible debt during the previous three years; or (iv) the
date on which we are deemed to be a large accelerated filer under the rules of
the SEC.

We are also a "smaller reporting company," as defined in the Exchange Act. We
may continue to be a smaller reporting company even after we are no longer an
emerging growth company. We may take advantage of certain of the scaled
disclosures available to smaller reporting companies and will be able to take
advantage of these scaled disclosures for so long as our voting and non-voting
common stock held by non-affiliates is less than $250.0 million measured on the
last business day of our second fiscal quarter, or our annual revenue is less
than $100.0 million during the most recently completed fiscal year and our
voting and non-voting common stock held by non-affiliates is less than $700.0
million measured on the last business day of our second fiscal quarter. If we
are a smaller reporting company at the time, we cease to be an emerging growth
company, we may continue to rely on exemptions from certain disclosure
requirements that are available to smaller reporting companies. Specifically, as
a smaller reporting company we may choose to present only the two most recent
fiscal years of audited consolidated financial statements in our Annual Report
on Form 10-K and, similar to emerging growth companies, smaller reporting
companies have reduced disclosure obligations regarding executive compensation.
