Executive Summary



We are a worldwide leader in the design, development, manufacture and support of
process control tools that perform macro-defect inspection and metrology,
lithography systems, and process control analytical software used by
semiconductor and advanced packaging device manufacturers. We deliver
comprehensive solutions throughout the semiconductor fabrication process with
our families of proprietary products that provide critical yield-enhancing
information, enabling microelectronic device manufacturers to drive down costs
and time to market of their devices. We provide process and yield management
solutions used in both wafer processing facilities, often referred to as
"front-end" manufacturing, and in device packaging and test facilities, commonly
referred to as "back-end" manufacturing. Our advanced process control software
portfolio includes powerful solutions for standalone tools, groups of tools, or
factory-wide suites to enhance productivity and achieve significant cost
savings.

Our principal market is semiconductor capital equipment. Semiconductors packaged
as integrated circuits, or "chips", are used in consumer electronics, server and
enterprise systems, mobile computing (including smart phones and tablets), data
storage devices, and embedded automotive and control systems. Our core focus is
the measurement and control of the structure, composition, and geometry of
semiconductor devices as they are fabricated on silicon wafers to improve device
performance and manufacturing yields.

Our products and services are used by our customers who manufacture many types
of integrated circuits for a multitude of applications, each having unique
manufacturing challenges. This includes integrated circuits to enable
information processing and management (logic integrated circuits), memory
storage (NAND, 3D-NAND, NOR, and DRAM), analog devices (e.g., Wi-Fi and 5G radio
integrated circuits, power devices), MEMS sensor devices (accelerometers,
pressure sensors, microphones), image sensors, and other end markets including
components for hard disk drives, LEDs, and power management.

The semiconductor and electronics industries have also been characterized by
constant technological innovation. We believe that, over the long term, our
customers will continue to invest in advanced technologies and new materials to
enable smaller design rules and higher density applications that fuel demand for
process control equipment.

The following table summarizes certain key financial information for the periods indicated below (in thousands, except per share and percent data):

•
In fiscal 2022, revenue increased 27% compared to fiscal 2021, primarily due to
an increase in sales to memory customers in advanced nodes applications and OSAT
customers in specialty device and advanced packaging applications, partially
offset by an increase in sales to foundry customers for advanced node
applications.

Gross margin as a percentage of revenue was relatively flat at 54% for both fiscal 2022 and 2021 years. This was primarily driven by increased revenue volume, offset by unfavorable product mix and increased manufacturing costs due to inflationary pressures.


The increase in operating expenses in fiscal 2022 compared to fiscal 2021 was
primarily due to increases in research and development, and sales and marketing
expenses related to increased headcount, travel expenses and the write-off of
purchased in process research and development assets.

Our cash, cash equivalents and marketable securities balance increased to $547.8
million at the end of fiscal 2022 compared to $511.3 million at the end of
fiscal 2021. This increase was primarily the result of $136.7 million of cash
generated from operating activities. This source of cash was partially offset of
$65.3 million of cash used for the purchase of our common stock, $18.4 million
used for capital expenditures and $4.6 million used for the purchase of acquired
research and development assets.

The demand environment, particularly in memory and advanced nodes, has weakened,
and as a result, we expect a reduction in wafer fabrication equipment spending
in fiscal year 2023. We expect the regulatory conditions, and the slowing

economic environment, to negatively impact our financial results in fiscal year
2023. We believe that the semiconductor industry macroeconomics have not changed
and anticipate that the industry's long-term growth projections will normalize,
but in the short-term, the industry is seeing volatility and disruption due to
inflationary pressures, geopolitical unrest and the lingering effects of the
pandemic.

Key Events

Expanded U.S. Export Controls

In October 2022, BIS issued the October 2022 Export Controls related to the
Chinese semiconductor manufacturing, advanced computing, and supercomputer
industries. The October 2022 Export Controls include restrictions on certain
semiconductor integrated circuits, commodities containing such integrated
circuits, and semiconductor manufacturing equipment and restrict the ability of
U.S. persons to support the development or production of integrated circuits at
certain semiconductor fabrication facilities in China. The primary impact of the
October 2022 Export Controls on Onto Innovation is that we are now required to
obtain a license to do business with certain Chinese customers that produce
certain advanced computing integrated circuits. The October 2022 Export Controls
also expanded the scope of foreign-produced items subject to license
requirements to entities on the Entity List that are located in China. In 2022,
BIS also added a number of Chinese companies to the Unverified List and Entity
List, including Yangtze Memory Technologies Co., Ltd.

We may experience a temporary loss of revenues while we apply for licenses
needed to continue doing business with certain customers affected by the new
export rules. A failure to obtain required license could result in a reduction
of anticipated revenues. We have assessed and will continue to assess the impact
of the October 2022 Export Controls and the addition of new entities to the
Unverified List and Entity List on our business, financial condition and results
of operations. We have estimated these new restrictions will negatively impact
our revenue by approximately $80.0 million for fiscal year 2023.

Impact of COVID-19 and the Global Semiconductor Supply Shortage



To date, the COVID-19 pandemic has disrupted the way that we conduct business
but has not had a material adverse impact on our operations. We have experienced
some delays in customer deliveries. Additionally, we are impacted by the global
shortage in electronic components and inflationary pressures. Our supply chain
is strained in some cases as the availability of materials, logistics and
freight options are challenging in many jurisdictions, which have resulted in
long lead times, rising prices and supply chain disruptions. We expect supply
chain shortages as well as inflationary cost pressures to persist into fiscal
year 2023. While demand for our products has remained strong, further
disruptions to our supply chain in connection with the sourcing of materials,
inflationary pressures, equipment and engineering support, and services from
geographic areas that have been impacted by COVID-19 may pose risks to our
business, results of operations and financial condition. We are continuing to
serve our customers while taking appropriate precautionary measures to provide a
safe work environment for our employees and customers.

For a discussion of certain risks related to the international nature of our
business and our operations and the COVID-19 pandemic and the resulting economic
impact and supply chain issues, see Part I, Item 1A - Risk Factors of this 2022
Form 10-K.

Results of Operations for 2022, 2021 and 2020



Revenue. Our revenue is derived from the sale of our systems and software, spare
parts, and services. Our revenue was $1,005.2 million, $788.9 million and $556.5
million for the years ended December 31, 2022, January 1, 2022 and December 26,
2020, respectively. This represents an increase of 27.4% from 2021 to 2022 and
an increase of 41.8% from 2020 to 2021.

The following table lists, for the periods indicated, the different sources of our revenue in dollars (thousands) and as percentages of our total revenue:



                                                    Year Ended
                           December 31,              January 1,             December 26,

Total systems and software revenue increased $196.6 million for the year ended
December 31, 2022, as compared to the year ended January 1, 2022, primarily due
to an increase in overall demand for our products from semiconductor industry
customers, particularly in advanced nodes applications, and specialty devices
and advanced packaging. The year-over-year change in systems revenue was
primarily due to an increase in units shipped in our metrology and inspection
product lines. Parts and services revenue is generated from part sales,
maintenance service contracts, and system upgrades, as well as time and material
billable service calls. During fiscal 2022, the increase in parts and services
revenue was primarily due to increased spending by our customers on system
upgrades and repairs of existing systems.

Total systems and software revenue increased $218.7 million for the year ended
January 1, 2022, as compared to the year ended December 26, 2020, primarily due
to an increase in overall demand for our products from semiconductor industry
customers, particularly in specialty devices and advanced packaging and advanced
nodes applications, and the inclusion of $22.3 million of revenue from the
Inspectrology acquisition. The year-over-year change in systems revenue was
primarily due to an increase in units shipped in our metrology and inspection
product lines. Parts and services revenue is generated from part sales,
maintenance service contracts, and system upgrades, as well as time and material
billable service calls. During fiscal 2021, the increase in parts and services
revenue was primarily due to increased spending by our customers on system

Total revenue               100 %            100 %              100 %


The overall Asia region continues to account for a majority of our revenues as a substantial amount of the worldwide capacity investments for semiconductor manufacturing continue to occur in this region and we expect that trend to continue.



Gross Profit. Our gross profit has been and will likely continue to be affected
by a variety of factors, including manufacturing efficiencies, provision for
excess and obsolete inventory, pricing by competitors or suppliers, new product
introductions, production volume, inventory step-up from purchase accounting,
customization and reconfiguration of systems, international and domestic sales
mix, system and software product mix, and parts and services margins. Our gross
profit was $539.2 million, $429.1 million and $278.5 million for the years ended
December 31, 2022, January 1, 2022, and December 26, 2020, respectively. Our
gross profit represented 53.6%, 54.4% and 50.0% for the years ended December 31,
2022, January 1, 2022, and December 26, 2020, respectively. The decrease in
gross profit as a percentage of revenue from 2021 to 2022 was primarily due to
continued supply chain cost increases in the 2022 fiscal period, partially
offset by higher factory utilization associated with increased sales volume
during the 2022 fiscal period. The increase in gross profit as a percentage of
revenue from 2020 to 2021 was primarily due to higher factory utilization
associated with stronger sales levels in the 2021 fiscal period, inventory
reserve charges for a discontinued product line and the sale of inventory
written-up to fair value upon the 2019 Merger in the 2020 fiscal period. This
increase in gross profit was partially offset by supply chain cost increases in
the 2021 fiscal period.

Operating Expenses.

Our operating expenses consist of:


Research and Development. We believe that it is critical to continue to make
substantial investments in research and development to ensure the availability
of innovative technology that meets the current and projected requirements of
our customers' most advanced designs. We have maintained, and intend to
continue, our commitment to investing in research and development in order to
continue to offer new products and technologies. Accordingly, we devote a
significant portion of our technical, management and financial resources to
research and development programs. Research and development expenditures consist
primarily of salaries and related expenses of employees engaged in research,
design and development activities. They also include consulting fees, the cost
of related supplies and legal costs to defend our intellectual property. Our
research and development expenses were $112.0 million, $96.1 million and $84.6
million in fiscal years 2022, 2021 and 2020, respectively. The year-over-year
dollar increase from 2021 through 2022 was primarily due to increased costs
related to new product initiatives, increased headcount and the write-off of
purchased in process research and development assets. The year-over-year dollar
increase from 2020 through 2021 was primarily due to increased costs related to
new product initiatives and increased variable compensation plan costs. We
continue to maintain our commitment to investing in new product development and
enhancement to existing products.


Sales and Marketing. Sales and marketing expenses are primarily comprised of
salaries and related costs for sales and marketing personnel, as well as
commissions and other non-personnel related expenses. Our sales and marketing
expenses were $65.7 million, $57.2 million and $48.1 million in fiscal years
2022, 2021 and 2020, respectively. The year-over-year dollar increase from 2021
through 2022 was primarily due to increased headcount, including variable
compensation plan costs and higher travel related expenses. The year-over-year
dollar increase from 2020 through 2021 was primarily due to increased personnel
costs, including variable compensation plan costs.

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

Table of Contents


General and Administrative. General and administrative expenses are primarily
comprised of salaries and related costs for general administrative personnel, as
well as other non-personnel related expenses. Our general and administrative
expenses were $69.6 million, $68.0 million and $65.3 million in fiscal years
2022, 2021 and 2020, respectively. The year-over-year dollar increase from 2021
through 2022 was primarily due to increased headcount, including variable
compensation plan costs. The year-over-year dollar increase from 2020 through
2021 was primarily due to increased personnel costs, including variable
compensation plan costs.


Amortization of Identifiable Intangible Assets. Amortization of identifiable
intangible assets, primarily purchased technology, was $55.3 million, $51.4
million and $53.7 million in fiscal years 2022, 2021 and 2020, respectively. The
year-over-year dollar increase from 2021 through 2022 was primarily due to a
full year of amortization being included in the 2022 fiscal period for IPR&D
that became classified as identifiable intangible assets in second half of 2021.
The year-over-year dollar decrease from 2020 through 2021 was primarily due to
certain intangible assets becoming fully amortized, partially offset by
amortization for newly acquired intangible assets in 2021.

Interest income, net. In fiscal years 2022, 2021 and 2020, net interest income
was $5.0 million, $1.2 million and $2.9 million, respectively. The increase in
net interest income from 2021 to 2022 was due to higher average balances and
higher interest rates during the 2022 period. The decrease in net interest
income from 2020 to 2021 was due to lower interest rates during the 2021 period.

Income taxes. The following table provides details of income tax (dollars in
millions):

                                                             Year Ended
                                          December 31,       January 1,       December 26,
                                              2022              2022              2020
Income before provision (benefit) for
income taxes                              $       241.6     $       155.7     $        26.9
Provision (benefit) for income taxes      $        18.3     $        13.3     $        (4.2 )
Effective tax rate                                  7.6 %             8.6 %           (15.5 )%


The income tax provision differs from the federal statutory income tax rate of
21% for 2022 primarily due to a benefit related to the Foreign Derived
Intangible Income Deduction ("FDII") of $25.4 million, excess benefits related
to stock compensation of $3.5 million, tax benefits for research and development
credits of $7.1 million, and a one-time benefit of $1.5 million related to the
recognition of a tax benefit associated with the lapse of a statute of
limitations. These benefits were partially offset by the inclusion of U.S. tax
on foreign source income of $1.4 million and non-deductible officer's
compensation of $1.9 million.

The income tax provision differs from the federal statutory income tax rate of
21% for 2021 primarily due to a benefit related to the Foreign Derived
Intangible Income Deduction ("FDII") of $11.1 million, excess benefits related
to stock compensation of $3.8 million, tax benefits for research and development
credits of $3.6 million, tax benefit from foreign income being taxed at lower
rates of $3.8 million, and a one-time benefit of $2.0 million from a reduction
to recorded tax reserve related to a lapse of statute of limitations. These
benefits were partially offset by the inclusion of U.S. tax on foreign source
income of $1.7 million.

The income tax provision differs from the federal statutory income tax rate of
21% for 2020 primarily due to a benefit related to the FDII of $4.3 million, tax
benefits for research and development credits of $4.9 million, and a one-time
benefit related to the closure of an IRS audit for tax years 2016 through 2018
of $2.9 million. These benefits were partially offset by the inclusion of Global
Intangible Low-Taxed Income ("GILTI") of $2.0 million.

Our future effective income tax rate depends on various factors, such as future
impacts of the Tax Act, possible further tax legislation, the geographic
composition of our pre-tax income, the amount of our pre-tax income as business
activities fluctuate, non-deductible expenses incurred in connection with
acquisitions and research and development credits as a percentage of aggregate
pre-tax income.

On March 27, 2020, the "Coronavirus Aid, Relief and Economic Security Act" (the
"CARES Act") was enacted. The CARES Act includes provisions relating to
refundable payroll tax credits, deferral of the employer portion of certain
payroll taxes, net operating loss carryback periods, alternative minimum tax
credit refunds, modifications to the net interest deduction limitations and
technical corrections to tax depreciation methods for qualified improvement
property. The Company filed a claim for a refund of prior years' income taxes
paid under the provisions of the CARES Act which resulted in a tax benefit of
$1.9 million as the 2019 net operating loss was carried back to a year with
higher tax rates.

Unanticipated changes in our tax provisions or exposure to additional tax
liabilities could affect our profitability and cash flow. We are subject to
income and other taxes in the United States and foreign jurisdictions. Changes
in applicable U.S. (federal, state and local) or foreign tax laws and
regulations, or their interpretation and application, including the possibility
of retroactive effect, have affected and could continue to affect our tax
expense and profitability as, for example, they did in 2017

upon passage of the Tax Cuts and Jobs Act. In addition, the final determination
of any state or federal tax audits or related litigation, in particular with
regard to the sustainment of our positions on research credits and timing of
revenue recognition under IRC Section 451(b), could be materially different from
our historical income tax provisions and accruals.

Beginning in 2022, the TCJA eliminates the existing option to deduct research
and development expenditures and requires taxpayers to amortize them over five
years for U.S. incurred expenditures and fifteen years for non-U.S. expenditures
pursuant to IRC Section 174. Although Congress has considered legislation that
would defer the amortization requirement to later years, we have no assurance
that the provision will be repealed or otherwise modified. If the requirement is
not modified, it will continue to reduce our cash flows for 2023. Changes in our
tax provisions or an increase in our tax liabilities, whether due to changes in
applicable laws and regulations, the interpretation or application thereof, or a
final determination of tax audits or litigation or agreements, could have a
material adverse effect on our financial position, results of operations and/or
cash flows.

Liquidity and Capital Resources



At December 31, 2022, we had $547.8 million of cash, cash equivalents and
marketable securities and $974.3 million in working capital. At January 1, 2022,
we had $511.3 million of cash, cash equivalents and marketable securities and
$793.6 million in working capital.

Net cash and cash equivalents provided by operating activities for the years
ended December 31, 2022, January 1, 2022 and December 26, 2020 totaled $136.7
million, $175.3 million and $106.0 million, respectively.


Cash provided by operating activities decreased in fiscal 2022 compared to
fiscal 2021 primarily due to an increase in inventories of $36.7 million, an
increase in accounts receivable of $37.3 million, an increase in income taxes of
$6.3 million, and an increase in prepaid expenses and other assets of $4.2
million, partially offset by higher net income, adjusted to exclude the effect
of non-cash charges, of $67.3 million, an increase in accounts payable of $11.0
million and an increase in accrued and other liabilities of $10.4 million.


Cash provided by operating activities increased in fiscal 2021 compared to
fiscal 2020 primarily due to higher net income, adjusted to exclude the effect
of non-cash charges of $91.2 million, an increase in accrued and other
liabilities of $3.8 million and an increase in income taxes of $2.5 million,
partially offset by an increase in inventories of $14.7 million, an increase in
prepaid expenses and other assets of $12.2 million and an increase in accounts
receivable of $2.0 million.

Net cash and cash equivalents used in investing activities for the years ended December 31, 2022, January 1, 2022 and December 26, 2020 was $55.7 million, $141.8 million and $48.6 million, respectively.

During the year ended December 31, 2022, net cash used in investing activities included purchases of marketable securities, net of proceeds from sales of marketable securities of $32.6 million, purchase of business net of cash acquired of $4.6 million, and purchases of property, plant and equipment of $18.4 million.


During the year ended January 1, 2022, net cash used in investing activities
included purchases of marketable securities, net of proceeds from sales of
marketable securities of $106.0 million, purchase of business net of cash
acquired of $23.8 million, and purchases of property, plant and equipment of
$12.0 million.


During the year ended December 26, 2020, net cash used in investing activities
included purchases of marketable securities, net of proceeds from sales of
marketable securities of $47.6 million and purchases of property, plant and
equipment of $3.8 million, partially offset by cash received from convertible
note receivable of $2.8 million.

Net cash used in financing activities was $68.4 million and $53.7 million for
the year ended December 31, 2022 and December 26, 2020, respectively. For the
year ended January 1, 2022 financing activities provided $2.7 million.


During the year ended December 31, 2022, financing activities primarily used
cash for repurchases of common stock of $65.3 million, tax payments related to
shares withheld to satisfy employee tax obligations in connection with the
vesting of awards under share-based compensation plans of $8.9 million and
payments related to contingent consideration for acquired business of $2.3
million, partially offset by proceeds from sale of shares through share-based
compensation plans of $8.1 million.


During the year ended January 1, 2022, financing activities provided cash from
shares issued through share-based compensation plans of $10.1 million, partially
offset by cash used to pay taxes related to shares withheld to satisfy employee
tax obligations in connection with the vesting of awards under share-based
compensation plans of $7.4 million.

During the year ended December 26, 2020, financing activities used cash primarily to purchase shares of our common stock under the share repurchase authorization of $52.0 million.

From time to time, we evaluate whether to acquire new or complementary
businesses, products or technologies. We may fund all of or a portion of the
price of these investments or acquisitions in cash, stock, or a combination of
cash and stock. In the first quarter of 2021, the Company acquired
Inspectrology, LLC for $24.0 million in cash.

In November 2020, the Onto Innovation Board of Directors approved a share
repurchase authorization, which allows us to repurchase up to $100 million worth
of shares of our common stock. Repurchases may be made through both public
market and private transactions from time to time. During the twelve months
ended December 31, 2022, we repurchased 1.0 million shares of common stock under
this repurchase authorization and those shares were subsequently retired. At
December 31, 2022, there was $34.7 million available for future share under this
share repurchase authorization.

For further information regarding our share repurchases, see Note 16 in the accompanying Notes to the Consolidated Financial Statements included in this Form 10-K.



We have a credit agreement with a bank that provides for a line of credit that
is secured by the marketable securities we have with the bank. We are permitted
to borrow up to 70% of the value of eligible securities held at the time the
line of credit is accessed. As of December 31, 2022, the available line of
credit was approximately $108.4 million with an available interest rate of 6.0%.
The credit agreement is available to us until such time that either party
terminates the arrangement at its discretion. To date, we have not utilized the
line of credit.

Our future capital requirements will depend on many factors, including the
timing and amount of our revenue and our investment decisions, which will affect
our ability to generate additional cash. We expect that our existing cash, cash
equivalents, marketable securities and availability under our line of credit
will be sufficient to meet our anticipated cash requirements for working
capital, capital expenditures and other cash needs for the next 12 months
following the filing of this Form 10-Q. Thereafter, if cash generated from
operations and financing activities is insufficient to satisfy our working
capital requirements, we may seek additional funding through bank borrowings,
sales of securities or other means. In addition, a reduction in or volatility
with respect to our stock price or a general market downturn could materially
impact our ability to sell securities on favorable terms or at all. There can be
no assurance that we will be able to raise any such capital on terms acceptable
to us or at all.

Contractual Obligations

The following table summarizes our significant contractual obligations at
December 31, 2022, and the effect such obligations are expected to have on our
liquidity and cash flows in future periods. We are currently unable to provide a
reasonably reliable estimate of the amount or periods when cash settlement of
this liability may occur (dollars in thousands).

Critical Accounting Policies and Estimates



Management's discussion and analysis of our financial condition and results of
operations are based upon our Consolidated Financial Statements included in this
Form 10-K, which have been prepared in accordance with accounting principles
generally accepted in the United States. We review the accounting policies we
use in reporting our financial results on a regular basis. The preparation of
these financial statements requires us to make estimates and judgments that
affect the reported amounts of assets, liabilities, revenue and expenses and
related disclosure of contingent assets and liabilities. On an ongoing basis, we
evaluate our estimates, including those related to revenue recognition, accounts
receivable, inventories, business acquisitions, intangible assets, share-based
payments, income taxes and warranty obligations. We base our estimates on
historical experience and on various other assumptions that are believed to be
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. Results may differ from these estimates due
to actual outcomes being different from those on which we based our assumptions.
These estimates and judgments are regularly reviewed by management on an ongoing
basis at the end of each quarter prior to the public release of our financial
results. We believe the following critical accounting policies affect our more
significant judgments and estimates used in the preparation of our Consolidated
Financial Statements.

                                       39

Revenue Recognition. Revenue is recognized when control of the promised goods or
services are transferred to our customers in an amount that reflects the
consideration we expect to be entitled to receive in exchange for those goods or
services. We account for a contract when it has approval and commitment from
both parties, the rights of the parties and payment terms are identified, the
contract has commercial substance and collectability of consideration is
probable.

We account for shipping and handling activities as the fulfillment of a promise
to transfer goods to the customer and therefore record these activities under
the caption "Cost of revenue." Sales tax and any other taxes collected
concurrent with revenue producing activities are excluded from revenue.
Incidental items that are immaterial in the context of the contract are
recognized as expense.

Contracts with customers may include multiple performance obligations. For such
arrangements, we allocate revenue to each performance obligation based on its
relative standalone selling price. We generally determine standalone selling
prices based on the prices charged to customers or the expected cost-plus
margin.

Revenue from systems is recognized when we transfer control of the product to
our customer. To indicate transfer of control, we must have a present right to
payment, legal title must have passed to the customer and the customer must have
the significant risks and rewards of ownership. We generally transfer control
for system sales when the customer or the customer's agent picks up the system
at our facility. We provide an assurance warranty on our systems for a period of
twelve to fourteen months against defects in material and workmanship. We
provide for the estimated cost of product warranties at the time revenue is
recognized.

Depending on the terms of the systems arrangement, we may also defer the
recognition of a portion of the consideration expected to be received because we
have to satisfy a future obligation (e.g., installation and extended
warranties). We use an observable price to determine the standalone selling
price for separate performance obligations or a cost-plus margin approach when
one is not available.

Revenue from software licenses, which is primarily sold without systems, is
recognized upfront at the point in time when the software is made available to
the customer. Software licenses provide the customer with limited rights to use
the software. Revenue from licensing support and maintenance is recognized as
the support and maintenance are provided, which is over the contract period.

Revenue from parts is recognized when we transfer control of the product, which typically occurs when we ship the product from our facilities to the customer.



Revenue from services primarily consists of service contracts, which provide
additional maintenance coverage beyond our assurance warranty on our products,
service labor, consulting and training. Revenue from service contracts is
recognized ratably over the term of the service contract. Revenue from service
labor and consulting is recognized as services are performed.

We record contract liabilities when the customer has been billed in advance of
completing our performance obligations. These amounts are recorded as deferred
revenue in the Consolidated Balance Sheets.

Business combinations. We account for business combinations under the
acquisition method of accounting, which requires us to recognize separately from
goodwill the assets acquired, and the liabilities assumed at their acquisition
date fair values. While we use our best estimates and assumptions to accurately
value assets acquired and liabilities assumed at the acquisition date as well as
contingent consideration, where applicable, our estimates are inherently
uncertain and subject to refinement. As a result, during the measurement period,
which may be up to one year from the acquisition date, we record adjustments to
the assets acquired and liabilities assumed with the corresponding offset to
goodwill. Upon the conclusion of the measurement period or final determination
of the values of assets acquired or liabilities assumed, whichever comes first,
any subsequent adjustments are recognized in our consolidated statements of
operations. Accounting for business combinations requires our management to make
significant estimates and assumptions, especially at the acquisition date
including our estimates for intangible assets, contractual obligations assumed,
restructuring liabilities, pre-acquisition contingencies, and contingent
consideration, where applicable. Although we believe the assumptions and
estimates we have made in the past have been reasonable and appropriate, they
are based, in part, on historical experience and information obtained from the
management of the acquired companies and are inherently uncertain. Estimates in
valuing certain acquired intangible assets under the income approach include
growth in future expected cash flows from product sales, acquired technologies,
technology obsolescence rates, estimated cash flows from the projects when
completed and discount rates. Unanticipated events and circumstances may occur
that may affect the accuracy or validity of such assumptions, estimates or
actual results.

Excess and Obsolete Inventory. Inventories are stated at the lower of cost or
net realizable value. Net realizable value is the estimated selling prices in
the ordinary course of business, less predictable costs of completion, disposal
and transportation. Cost is generally determined on a first-in, first-out basis,
and includes material, labor and manufacturing overhead costs. We review and set
standard costs as needed, but at a minimum, on an annual basis, at current
manufacturing costs in order to approximate actual costs. We maintain reserves
for our excess and obsolete inventory equal to the difference between the cost

                                       40

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

Table of Contents




of inventory and the estimated market value based upon assumptions about future
product lifecycles, product demand and market conditions. If actual product
lifecycles, product demand and market conditions are less favorable than those
originally projected by management, additional inventory write-downs may be
required.

Goodwill and Indefinite Lived Intangible Assets. Goodwill is tested for
impairment during the fourth quarter, or whenever events or circumstances
indicate that its carrying value may not be recoverable. Goodwill impairment is
tested at the reporting unit level, which is defined as an operating segment or
one level below the operating segment. The Company has three reporting units and
one operating segment. Goodwill is reviewed for impairment using either a
qualitative assessment or a quantitative goodwill impairment test. If the
Company chooses to perform a qualitative assessment and determine the fair value
more likely than not exceeds the carrying value, no further evaluation is
necessary. When the Company performs the quantitative goodwill impairment test,
it compares fair value to carrying value, which includes goodwill. If fair value
exceeds carrying value, the goodwill is not considered impaired. If the carrying
value is higher than the fair value, the difference would be recognized as an
impairment loss.

Intangible assets with indefinite lives, including in-process research and
development ("IPR&D"), are tested for impairment if impairment indicators arise
and, at a minimum, annually. However, the Company is permitted to first assess
qualitative factors to determine if a quantitative impairment test is necessary.
Further testing is only required if the entity determines, based on the
qualitative assessment, that it is more likely than not that an indefinite-lived
intangible asset's fair value is less than its carrying amount. Otherwise, no
further impairment testing is required. The indefinite-lived intangible asset
impairment test consists of a one-step analysis that compares the fair value of
the intangible asset with its carrying amount. If the carrying amount of an
intangible asset exceeds its fair value, an impairment loss is recognized in an
amount equal to that excess. We consider many factors in evaluating whether the
value of intangible assets with indefinite lives may not be recoverable,
including, but not limited to estimates of future cash flows, the discount rate,
terminal growth rates, general economic conditions, our outlook and market
performance of our industry and recent and forecasted financial performance.

There was no impairment of goodwill or IPR&D for the years presented.



Long-Lived Assets and Finite-Lived Acquired Intangible Assets. We periodically
review long-lived assets, other than goodwill, for impairment whenever changes
in events or circumstances indicate that the carrying amount of an asset may not
be recoverable. Assumptions and estimates used in the determination of
impairment losses, such as future cash flows and disposition costs, may affect
the carrying value of long-lived assets and the impairment of such long-lived
assets, if any, could have a material effect on our consolidated financial
statements. No such indicators were noted in 2022, 2021 or 2020.

Accounting for Income Taxes. As part of the process of preparing our
consolidated financial statements, we are required to estimate our current tax
exposure together with our temporary differences resulting from differing
treatment of items for tax and accounting purposes. These temporary differences
result in deferred tax assets and liabilities, which are included within our
consolidated balance sheet. We must then assess the likelihood that our deferred
tax assets will be recovered from future taxable income and to the extent we
believe that recovery is not likely, we must establish a valuation allowance.
Management judgment is required in determining our provision for income taxes
and any valuation allowance recorded against our deferred tax assets. The need
for a valuation allowance is based on our estimates of taxable income by
jurisdiction in which we operate and the period over which our deferred taxes
will be recoverable. In the event that actual results differ from these
estimates or we adjust these estimates in future periods, we may need to adjust
the valuation allowance, which could materially impact our financial position
and results of operations. At December 31, 2022 and January 1, 2022, we had
recorded valuation allowances of $11.8 million and $10.9 million on certain of
our deferred tax assets to reflect the deferred tax assets at the net amount
that is more likely than not to be realized. We evaluated the realizability of
the deferred tax assets based on positive earnings as well as the projected
earnings in future years and believe it is more likely than not that the
substantial majority of our deferred tax asset will be realized in the future
years. We will continue to monitor the realizability of the deferred tax assets
and evaluate the valuation allowance.

We recognize liabilities for uncertain tax positions based on a two-step
process. The first step requires us to determine if the weight of available
evidence indicates that the tax position has met the threshold for recognition;
therefore, we must evaluate whether it is more likely than not that the position
will be sustained on audit, including resolution of any related appeals or
litigation processes. The second step requires us to measure the tax benefit of
the tax position taken, or expected to be taken, in an income tax return as the
largest amount that is more than 50% likely of being realized when effectively
settled. This measurement step is inherently difficult and requires subjective
estimations of such amounts to determine the probability of various possible
outcomes. We reevaluate the uncertain tax positions each quarter based on
factors including, but not limited to, changes in facts or circumstances,
changes in tax law, effectively settled issues, and new audit activity. Such a
change in recognition or measurement could result in the recognition of a tax
benefit or an additional charge to the tax provision in the period.

Although we believe the measurement of our liabilities for uncertain tax
positions is reasonable, no assurance can be given that the final outcome of
these matters will not be different than what is reflected in the historical
income tax provisions and accruals. If additional taxes are assessed as a result
of an audit or litigation, it could have a material effect on our income tax
provision and net income in the period or periods for which that determination
is made.
