NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Amounts in thousands except per share data)

(Unaudited)

Therefore, the Company encourages investors and others interested in Mercury to review the information the Company posts on the social media and other communication channels listed on its website.

B.Summary of Significant Accounting Policies

BASIS OF PRESENTATION

The accompanying consolidated financial statements have been prepared by the Company in accordance with Generally Accepted Accounting Principles (“GAAP”) in the United States of America for interim financial information and with the instructions to the Form 10-Q and Article 10 of Regulation S-X. Certain information and footnote disclosures normally included in annual consolidated financial statements have been condensed or omitted pursuant to those rules and regulations; however, in the opinion of management the financial information reflects all adjustments, consisting of adjustments of a normal recurring nature, necessary for fair presentation. These consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes for the fiscal year ended July 2, 2021 which are contained in the Company’s Annual Report on Form 10-K filed with the SEC on August 17, 2021. The results for the first quarter ended October 1, 2021 are not necessarily indicative of the results to be expected for the full fiscal year.

The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation.

All references to the first quarter of fiscal 2022 are to the quarter ended October 1, 2021. There were 13 weeks during the first quarters ended October 1, 2021 and October 2, 2020, respectively.

USE OF ESTIMATES

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates.

BUSINESS COMBINATIONS

The Company utilizes the acquisition method of accounting under ASC 805, Business Combinations, (“ASC 805”), for all transactions and events in which it obtains control over one or more other businesses, to recognize the fair value of all assets and liabilities acquired, even if less than one hundred percent ownership is acquired, and in establishing the acquisition date fair value as the measurement date for all assets and liabilities assumed. The Company also utilizes ASC 805 for the initial recognition and measurement, subsequent measurement and accounting, and disclosure of assets and liabilities arising from contingencies in business combinations.

7

FOREIGN CURRENCY

Local currencies are the functional currency for the Company’s subsidiaries in Switzerland, the United Kingdom, France, Japan, Spain and Canada. The accounts of foreign subsidiaries are translated using exchange rates in effect at period-end for assets and liabilities and at average exchange rates during the period for results of operations. The related translation adjustments are reported in Accumulated other comprehensive loss (“AOCL”) in shareholders’ equity. Gains (losses) resulting from non-U.S. currency transactions are included in Other expense, net in the Consolidated Statements of Operations and Comprehensive (Loss) Income and were immaterial for all periods presented.

REVENUE RECOGNITION

The Company recognizes revenue in accordance with ASC 606, Revenue from Contracts with Customers, (“ASC 606”). Revenues are derived from the sales of products that are grouped into one of the following three categories: (i) components; (ii) modules and sub-assemblies; and (iii) integrated subsystems. The Company also generates revenues from the performance of services, including systems engineering support, consulting, maintenance and other support, testing and installation. Each promised good or service within a contract is accounted for separately under the guidance of ASC 606 if they are distinct. Promised goods or services not meeting the criteria for being a distinct performance obligation are bundled into a single performance obligation with other goods or services that together meet the criteria for being distinct. The appropriate allocation of the transaction price and recognition of revenue is then determined for the bundled performance obligation.

Revenue recognized at a point in time generally relates to contracts that include a combination of components, modules and sub-assemblies, integrated subsystems and related system integration or other services. Contracts with distinct performance obligations recognized at a point in time, with or without an allocation of the transaction price, totaled 47% and 64% of revenues for the first quarters ended October 1, 2021 and October 2, 2020, respectively.

The Company also engages in long-term contracts for development, production and service activities and recognizes revenue for performance obligations over time. These long-term contracts involve the design, development, manufacture, or modification of complex modules and sub-assemblies or integrated subsystems and related services. Long-term contracts include both fixed-price and cost reimbursable contracts. The Company’s cost reimbursable contracts typically include cost-plus fixed fee and time and material contracts.

Total revenue recognized under long-term contracts over time was 53% and 36% of total revenues for the first quarters ended October 1, 2021 and October 2, 2020, respectively.

The Company generally does not provide its customers with rights of product return other than those related to assurance warranty provisions that permit repair or replacement of defective goods over a period of 12 to 36 months. The Company accrues for anticipated warranty costs upon product shipment. The Company does not consider activities related to such assurance warranties, if any, to be a separate performance obligation. The Company does offer separately priced extended warranties which generally range from 12 to 36 months that are treated as separate performance obligations. The transaction price allocated to extended warranties is recognized over time in proportion to the costs expected to be incurred in satisfying the obligations under the contract.

All revenues are reported net of government assessed taxes (e.g., sales taxes or value-added taxes). Refer to Note L for disaggregation of revenue for the period.

ACCOUNTS RECEIVABLE

Accounts receivable, net, represents amounts that have been billed and are currently due from customers. The Company maintains an allowance for credit losses to provide for the estimated amount of receivables that will not be collected. The Company provides credit to customers in the normal course of business. The Company performs ongoing credit evaluations of its customers’ financial condition and limits the amount of credit extended as necessary. The allowance is based upon an assessment of the customer's credit worthiness, reasonable forecasts about the future, history with the customer, and the age of the receivable balance. The Company typically invoices a customer upon shipment of the product (or completion of a service) for contracts where revenue is recognized at a point in time. For contracts where revenue is recognized over time, the invoicing events are typically based on specified performance obligation deliverables or milestone events, or quantifiable measures of performance.

8

CONTRACT BALANCES    

Contract balances result from the timing of revenue recognized, billings and cash collections, and the generation of contract assets and liabilities. Contract assets represent revenue recognized in excess of amounts invoiced to the customer and the right to payment is not subject to the passage of time. Contract assets are presented as unbilled receivables and costs in excess of billings on the Company’s Consolidated Balance Sheets. Contract liabilities consist of deferred product revenue, billings in excess of revenues, deferred service revenue, and customer advances. Deferred product revenue represents amounts that have been invoiced to customers, but are not yet recognizable as revenue because the Company has not satisfied its performance obligations under the contract. Billings in excess of revenues represents milestone billing contracts where the billings of the contract exceed recognized revenues. Deferred service revenue primarily represents amounts invoiced to customers for annual maintenance contracts or extended warranty contracts, which are recognized over time in proportion to the costs expected to be incurred in satisfying the obligations under the contract. Customer advances represent deposits received from customers on an order. Contract liabilities are included in deferred revenue and the long-term portion of deferred revenue is included within other non-current liabilities on the Company’s Consolidated Balance Sheets. Contract balances are reported in a net position on a contract-by-contract basis.

The contract asset balances were $194,367 and $162,921 as of October 1, 2021 and July 2, 2021, respectively. The contract asset balance increased due to growth in revenue recognized over time and timing of billable events under long-term contracts during the first quarter ended October 1, 2021. The contract liability balances were $29,438 and $35,201 as of October 1, 2021 and July 2, 2021, respectively. The decrease was due to lower billings in excess of revenues.

Revenue recognized for the first quarter ended October 1, 2021 that was included in the contract liability balance at July 2, 2021 was $13,137. Revenue recognized for the first quarter ended October 2, 2020 that was included in the contract liability balance at July 3, 2020 was $9,030.

REMAINING PERFORMANCE OBLIGATIONS

The Company includes in its computation of remaining performance obligations customer orders for which it has accepted signed sales orders. The definition of remaining performance obligations excludes contracts with original expected durations of less than one year, as well as those contracts that provide the customer with the right to cancel or terminate the order with no substantial penalty, even if the Company’s historical experience indicates the likelihood of cancellation or termination is remote. As of October 1, 2021, the aggregate amount of the transaction price allocated to remaining performance obligations was $373,904. The Company expects to recognize approximately 69% of its remaining performance obligations as revenue in the next 12 months and the balance thereafter.

WEIGHTED-AVERAGE SHARES

Weighted-average shares were calculated as follows:

	First Quarters Ended
	October 1, 2021	October 2, 2020
Basic weighted-average shares outstanding	55,376	54,883
Effect of dilutive equity instruments	—	456
Diluted weighted-average shares outstanding	55,376	55,339

Equity instruments to purchase 474 and 203 shares of common stock were not included in the calculation of diluted net earnings per share for the first quarters ended October 1, 2021 and October 2, 2020, respectively, because the equity instruments were anti-dilutive.

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, an amendment of the FASB Accounting Standards Codification. The amendments in this ASU provide optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. The amendments in this ASU are elective and apply to all entities, subject to meeting certain criteria, that have contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. The amendments in this Update are effective for all entities as of March 12, 2020 through December 31, 2022. The Company is currently evaluating the effect that this standard will have on its consolidated financial statements and related disclosures.

In October 2021, the FASB issued ASU No. 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, an amendment of the FASB Accounting Standards

9

Codification. The amendments in this ASU address diversity and inconsistency related to the recognition and measurement of contract assets and contract liabilities acquired in a business combination and require that an acquirer recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606, Revenue from Contracts with Customers. Under current U.S. GAAP, an acquirer generally recognizes assets and liabilities assumed in a business combination, including contract assets and liabilities arising from revenue contracts with customers, at fair value on the acquisition date. ASU No. 2021-08 will result in the acquirer recording acquired contract assets and liabilities on the same basis that would have been recorded by the acquiree before the acquisition under Topic 606. This ASU is effective for fiscal years beginning after December 15, 2022, with early adoption permitted, including adoption in an interim period. The Company is currently evaluating the effect that this standard will have on its consolidated financial statements and related disclosures.

RECENTLY ADOPTED ACCOUNTING PRONOUNCEMENTS

Effective July 3, 2021 the Company adopted ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, an amendment of the FASB Accounting Standards Codification. The amendments in this ASU simplify the accounting for income taxes by removing certain exceptions for intraperiod tax allocations and deferred tax liabilities for equity method investments and add guidance as to whether a step-up in tax basis of goodwill relates to a business combination or a separate transaction. This adoption did not have a material impact to the Company's consolidated financial statements or related disclosures.

C. Acquisitions

PENTEK ACQUISITION

On May 27, 2021, the Company acquired Pentek Technologies, LLC and Pentek Systems, Inc. (collectively, "Pentek"). for a purchase price of $65,000, subject to net working capital and net debt adjustments. Based in Upper Saddle River, New Jersey, Pentek is a leading designer and manufacturer of ruggedized, high-performance, commercial off-the-shelf software-defined radio and data acquisition boards, recording systems and subsystems for high-end commercial and defense applications. The acquisition and associated transaction expenses were funded through a combination of cash on hand and Mercury's existing revolving credit facility (the "Revolver").

The following table presents the net purchase price and the fair values of the assets and liabilities of Pentek on a preliminary basis:

	Amounts
Consideration transferred
Cash paid at closing	$	65,668
Less cash acquired	(746)
Net purchase price	$	64,922
Estimated fair value of tangible assets acquired and liabilities assumed
Cash	$	746
Accounts receivable	1,370
Inventory	6,575
Fixed assets	152
Other current and non-current assets	2,864
Accounts payable	(1,016)
Accrued expenses	(520)
Other current and non-current liabilities	(4,090)
Estimated fair value of net tangible assets acquired	6,081
Estimated fair value of identifiable intangible assets	24,110
Estimated goodwill	35,477
Estimated fair value of net assets acquired	65,668
Less cash acquired	(746)
Net purchase price	$	64,922

The amounts above represent the preliminary fair value estimates as of October 1, 2021 and are subject to subsequent adjustment as the Company obtains additional information during the measurement period and finalizes its fair value estimates. The preliminary identifiable intangible asset estimate includes customer relationships of $15,560 with a useful life of 21 years, completed technology of $6,340 with a useful life of seven years and backlog of $2,210 with a useful life of one year. Any subsequent adjustments to these fair value estimates occurring during the measurement period will result in an adjustment to goodwill.

The goodwill of $35,477 largely reflects the potential synergies and expansion of the Company's offerings across product lines and markets complementary to the Company's existing products and markets. The goodwill from this acquisition is included in the Microelectronics reporting unit. The transaction was a combination of asset and stock, with the asset portion of goodwill being deductible for tax purposes. The Company has estimated the tax value of the intangible assets from this transaction and is amortizing the amount over 15 years for tax purposes. As of October 1, 2021, the Company had $29,703 of goodwill deductible for tax purposes.

On December 7, 2020, the Company signed a definitive agreement to acquire Physical Optics Corporation ("POC") for a purchase price of $310,000, subject to net working capital and net debt adjustments. On December 30, 2020, the transaction closed and the Company acquired POC. Based in Torrance, California, POC expands the Company's global avionics business and its collective footprint in the platform and mission management market. The Company funded the acquisition through a combination of cash on hand and the Company's existing revolving credit facility (the "Revolver"). On May 28, 2021 the Company and representative of the former owners of POC agreed to post closing-adjustments totaling $2,641, which increased the Company’s net purchase price.

The following table presents the net purchase price and the fair values of the assets and liabilities of POC on a preliminary basis:

	Amounts
Consideration transferred
Cash paid at closing	$	251,229
Cash paid post closing	61,626
Working capital and net debt adjustment	(2,096)
Less cash acquired	(2,855)
Net purchase price	$	307,904
Estimated fair value of tangible assets acquired and liabilities assumed
Cash	$	2,855
Accounts receivable and Unbilled Receivables	28,022
Inventory	11,125
Fixed assets	23,236
Other current and non-current assets	16,453
Accounts payable	(3,777)
Accrued expenses	(5,572)
Other current and non-current liabilities	(32,999)
Estimated fair value of net tangible assets acquired	39,343
Estimated fair value of identifiable intangible assets	116,000
Estimated goodwill	155,416
Estimated fair value of net assets acquired	310,759
Less cash acquired	(2,855)
Net purchase price	$	307,904

The amounts above represent the preliminary fair value estimates as of October 1, 2021 and are subject to subsequent adjustment as the Company obtains additional information during the measurement period and finalizes its fair value estimates, including the ongoing assessment of collectability of receivable balances. The preliminary identifiable intangible asset estimate includes customer relationships of $83,000 with a useful life of 11 years, completed technology of $25,000 with a useful life of 9 years and backlog of $8,000 with a useful life of one year. Any subsequent adjustments to these fair value estimates occurring during the measurement period will result in an adjustment to goodwill.

The estimated goodwill of $155,416 largely reflects the potential synergies and expansion of the Company’s offerings across product lines and markets complementary to the Company’s existing products and markets and is not deductible for tax purposes. The goodwill from this acquisition is reported in the Processing reporting unit.

AVALEX ACQUISITION

On September 27, 2021, the Company announced that it had signed a definitive agreement to acquire Avalex Technologies Corporation (“Avalex”). Based in Gulf Breeze, Florida. Avalex is a provider of mission-critical avionics, including rugged displays, integrated communications management systems, digital video recorders, and warning systems. Pursuant to the terms of the agreement, the Company will acquire Avalex for an all-cash purchase price of $155,000, subject to net working capital and net debt adjustments. On November 5, 2021, the transaction closed and the Company acquired Avalex. See Note N "Subsequent Events" to the consolidated financial statements for further discussion.

D.Fair Value of Financial Instruments

The carrying values of cash and cash equivalents, including money market funds, restricted cash, accounts receivable and payable, and accrued liabilities approximate fair value due to the short-term maturities of these assets and liabilities. The Company determined the carrying value of long-term debt approximated fair value due to variable interest rates charged on the borrowings, which reprice frequently. As of October 1, 2021, the Company had no financial instruments required to be measured at fair value.

E. Inventory

Inventory is stated at the lower of cost (first-in, first-out) or net realizable value, and consists of materials, labor and overhead. On a quarterly basis, the Company uses consistent methodologies to evaluate inventory for net realizable value. Once an item is written down, the value becomes the new inventory cost basis. The Company reduces the value of inventory for excess and obsolete inventory, consisting of on-hand inventory in excess of estimated usage. The excess and obsolete inventory evaluation is based upon assumptions about future demand, historical usage, product mix and possible alternative uses. Inventory was comprised of the following:

	As of
		October 1, 2021		July 2, 2021
Raw materials		$	148,747	$	141,774
Work in process		63,380		58,087
Finished goods		22,276		21,779
Total		$	234,403	$	221,640

F.Goodwill

On August 3, 2021, Mercury announced a companywide effort, called 1MPACT, to lay the foundation for the next phase of the Company's value creation at scale. The goal of 1MPACT is to achieve Mercury's full growth, margin expansion and adjusted EBITDA potential over the next five years. In connection with 1MPACT, the Company realigned its internal organizational structure in the first quarter of fiscal 2022 shifting to two divisions, Processing and Microelectronics. The Mission division has now merged under the Processing division. There was no change to the Microelectronics division.

In accordance with FASB ASC 350, Intangibles-Goodwill and Other (“ASC 350”), the Company determines its reporting units based upon whether discrete financial information is available, if management regularly reviews the operating results of the component, the nature of the products offered to customers and the market characteristics of each reporting unit. A reporting unit is considered to be an operating segment or one level below an operating segment also known as a component. Component level financial information is reviewed by management across two divisions: Processing and Microelectronics. Accordingly, these were determined to be the Company's new reporting units.

The internal reorganization and change in reporting units qualified as a triggering event and required goodwill to be tested for impairment. As required by ASC 350, the Company tested goodwill for impairment immediately before and after the reorganization. As a result of these analyses, it was determined that goodwill was not impaired before or after the reorganization.

In the first quarter ended October 1, 2021, the Company assigned goodwill to the new reporting units based on the relative fair value of transferred operations.

The following table sets forth the changes in the carrying amount of goodwill for the first quarter ended October 1, 2021:

	Total
Balance at July 2, 2021	$	804,906
Goodwill adjustment for the POC acquisition	157
Goodwill adjustment for the Pentek acquisition	252
Balance at October 1, 2021	$	805,315

The Company performs its annual goodwill impairment test in the fourth quarter of each fiscal year.

G.Restructuring

During the first quarter ended October 1, 2021, the Company incurred $12,274 of restructuring and other charges. Restructuring and other charges of $7,338 related to severance costs associated with the elimination of 100 employees in manufacturing, SG&A and R&D based on changes in the business environment and to align with the internal organizational changes completed under 1MPACT. The remaining $4,936 of restructuring and other charges related to third-party consulting costs associated with 1MPACT.

All of the restructuring and other charges are classified as Operating expenses in the Consolidated Statements of Operations and Comprehensive (Loss) Income and any remaining severance obligations are expected to be paid within the next twelve months. The restructuring liability is classified as Accrued expenses in the Consolidated Balance Sheets.

The following table presents the detail of activity for the Company’s restructuring plans:

	Severance & Related
Balance at July 2, 2021	$	1,006
Restructuring and other charges	7,338
Cash paid	(2,009)
Balance at October 1, 2021	$	6,335

H.Income Taxes

The Company recorded an income tax (benefit) provision of $(441) and $2,198 on a (loss) income before income taxes of $(7,581) and $17,996 for the first quarters ended October 1, 2021 and October 2, 2020, respectively.

During the first quarters ended October 1, 2021 and October 2, 2020, the Company recognized a discrete tax provision of $715 related to stock-based compensation shortfalls and a discrete tax benefit of $2,480 related to excess benefits on stock-based compensation.

The effective tax rate for the first quarters ended October 1, 2021 and October 2, 2020 differed from the Federal statutory rate primarily due to Federal and State research and development credits, non-deductible compensation, stock-based compensation, and state taxes. In addition, during the first quarter ended October 1, 2021, the Company had certain unbenefited deferred tax assets.

During the first quarter ended October 1, 2021, there were no material changes to the Company's unrecognized tax positions.

Within the calculation of the Company's annual effective tax rate, the Company has used assumptions and estimates that may change as a result of future guidance and interpretation from the Internal Revenue Service (“IRS”).

I.Debt

REVOLVING CREDIT FACILITY

On September 28, 2018, the Company amended the Revolver to increase and extend the borrowing capacity to a $750,000, 5-year revolving credit line, with the maturity extended to September 28, 2023. As of October 1, 2021, the Company's outstanding balance of unamortized deferred financing costs was $2,689, which is being amortized to Other expense, net in the Consolidated Statements of Operations and Comprehensive (Loss) Income on a straight line basis over the term of the Revolver.

As of October 1, 2021, the Company was in compliance with all covenants and conditions under the Revolver and there were outstanding borrowings of $200,000 against the Revolver, resulting in interest expense of $595 for the first quarter ended October 1, 2021. There were outstanding letters of credit of $963 as of October 1, 2021.

J.Employee Benefit Plan

PENSION PLAN

The Company maintains a defined benefit pension plan (the “Plan”) for its Swiss employees, which is administered by an independent pension fund. The Plan is mandated by Swiss law and meets the criteria for a defined benefit plan under ASC 715, Compensation—Retirement Benefits (“ASC 715”), because participants of the Plan are entitled to a defined rate of return on contributions made. The independent pension fund is a multi-employer plan with unrestricted joint liability for all participating companies for which the Plan’s overfunding or underfunding is allocated to each participating company based on an allocation key determined by the Plan.

The Company recognizes a net asset or liability for the Plan equal to the difference between the projected benefit obligation of the Plan and the fair value of the Plan’s assets as required by ASC 715. The funded status may vary from year to year due to changes in the fair value of the Plan’s assets and variations on the underlying assumptions of the projected benefit obligation of the Plan. The Plan's funded status at October 1, 2021 was a net liability of $9,691, which is recorded in Other non-current liabilities on the Consolidated Balance Sheet. The Company recorded a net gain of $48 and $31 in AOCL during the first quarters ended October 1, 2021 and October 2, 2020, respectively. The Company recognized net periodic benefit costs of $269 and $413 associated with the Plan for the first quarters ended October 1, 2021 and October 2, 2020, respectively. The Company's total expected employer contributions to the Plan during fiscal 2022 are $1,165.

K.Stock-Based Compensation

STOCK INCENTIVE PLANS

At October 1, 2021, the aggregate number of shares authorized for issuance under the Company’s Amended and Restated 2018 Stock Incentive Plan (the “2018 Plan”) is 6,782 shares, including 710 shares rolled into the 2018 Plan that were available for future grant under the Company’s 2005 Stock Incentive Plan, as amended and restated (the “2005 Plan”) and 3,000 shares approved by the Company's shareholders on October 28, 2020. The 2018 Plan replaced the 2005 Plan. The shares authorized for issuance under the 2018 Plan will continue to be increased by any future cancellations, forfeitures or terminations (other than by exercise) of awards under the 2005 Plan. The foregoing does not affect any outstanding awards under the 2005 Plan, which remain in full force and effect in accordance with their terms. The 2018 Plan provides for the grant of non-qualified and incentive stock options, restricted stock, stock appreciation rights and deferred stock awards to employees and non-employees. Stock options must be granted with an exercise price of not less than 100% of the fair value of the Company’s common stock on the date of grant and the options generally have a term of seven years. There were 3,529 shares available for future grant under the 2018 Plan at October 1, 2021.

As part of the Company's ongoing annual equity grant program for employees, the Company grants performance-based restricted stock awards to certain executives and employees pursuant to the 2018 Plan. Performance awards vest based on the requisite service period subject to the achievement of specific financial performance targets. Based on the performance targets, some of these awards require graded vesting which results in more rapid expense recognition compared to traditional time-based vesting over the same vesting period. The Company monitors the probability of achieving the performance targets on a quarterly basis and may adjust periodic stock compensation expense accordingly based on its determination of the likelihood for reaching targets. The performance targets generally include the achievement of internal performance targets in relation to a peer group of companies.

EMPLOYEE STOCK PURCHASE PLAN

At October 1, 2021, the aggregate number of shares authorized for issuance under the Company’s 1997 Employee Stock Purchase Plan, as amended and restated (“ESPP”), is 2,300 shares, including 500 shares approved by the Company's shareholders on October 28, 2020. Under the ESPP, rights are granted to purchase shares of common stock at 85% of the lesser of the market value of such shares at either the beginning or the end of each six-month offering period. The ESPP permits employees to purchase common stock through payroll deductions, which may not exceed 10% of an employee’s compensation as defined in the ESPP. There were no shares issued under the ESPP during the first quarters ended October 1, 2021 and October 2, 2020, respectively. Shares available for future purchase under the ESPP totaled 428 at October 1, 2021.

STOCK AWARD ACTIVITY

The following table summarizes the status of the Company’s non-vested restricted stock awards and deferred stock awards since July 2, 2021:

	Non-vested Restricted Stock Awards
	Number of Shares	Weighted Average Grant Date Fair Value
Outstanding at July 2, 2021	1,013	$	70.77

STOCK-BASED COMPENSATION EXPENSE

The Company recognizes expense for its share-based payment plans in the Consolidated Statements of Operations and Comprehensive (Loss) Income in accordance with ASC 718, Compensation - Stock Compensation (“ASC 718”). The Company had $767 and $796 of capitalized stock-based compensation expense on the Consolidated Balance Sheets for the periods ended October 1, 2021 and July 2, 2021, respectively. Under the fair value recognition provisions of ASC 718, stock-based compensation cost is measured at the grant date based on the value of the award and is recognized as expense over the service period, net of estimated forfeitures.

The following table presents share-based compensation expenses included in the Company’s Consolidated Statements of Operations and Comprehensive (Loss) Income:

	First Quarters Ended
	October 1, 2021		October 2, 2020

L.Operating Segment, Geographic Information and Significant Customers

Operating segments are defined as components of an enterprise evaluated regularly by the Company's Chief Operating Decision Maker ("CODM") in deciding how to allocate resources and assess performance. During the first quarter of fiscal 2022, the Company announced its 1MPACT value creation initiative to promote scale as the organization continues to grow. The Company evaluated this internal reorganization under FASB ASC 280, Segment Reporting ("ASC 280") to determine whether this change has impacted the Company's single operating and reportable segment. The Company concluded this change had no effect given the CODM continues to evaluate and manage the Company on the basis of one operating and reportable segment. The Company utilized the management approach for determining its operating segment in accordance with ASC 280.

The geographic distribution of the Company’s revenues as determined by country in which the Company's legal subsidiary is domiciled is summarized as follows:

	U.S.		Europe		Asia Pacific		Eliminations		Total
FIRST QUARTER ENDED OCTOBER 1, 2021
Net revenues to unaffiliated customers	$	213,741	$	11,187	$	85	$	—	$	225,013
Inter-geographic revenues	1,559		729		—		(2,288)		—
Net revenues	$	215,300	$	11,916	$	85	$	(2,288)	$	225,013
FIRST QUARTER ENDED OCTOBER 2, 2020
Net revenues to unaffiliated customers	$	195,847	$	9,663	$	111	$	—	$	205,621
Inter-geographic revenues	240		344		—		(584)		—
Net revenues	$	196,087	$	10,007	$	111	$	(584)	$	205,621

The Company offers a broad family of products designed to meet the full range of requirements in compute-intensive, signal processing, image processing and command and control applications. To maintain a competitive advantage, the Company seeks to leverage technology investments across multiple product lines and product solutions.

The Company’s products are typically compute-intensive and require extremely high bandwidth and high throughput. These systems often must also meet significant SWaP constraints for use in aircraft, unmanned aerial vehicles, ships and other platforms and be ruggedized for use in harsh environments. The Company's products transform the massive streams of digital data created in these applications into usable information in real time. The systems can scale from a few processors to thousands of processors.

In recent years, the Company completed a series of acquisitions that changed its technological capabilities, applications and end markets. As these acquisitions and changes occurred, the Company's proportion of revenue derived from the sale of components in different technological areas, and modules, sub-assemblies and integrated subsystems which combine technologies into more complex diverse products has shifted. The following tables present revenue consistent with the Company's strategy of expanding its technological capabilities and program content. As additional information related to the Company’s products by end user, application, product grouping and/or platform is attained, the categorization of these products can vary over time. When this occurs, the Company reclassifies revenue by end user, application, product grouping and/or platform for prior periods. Such reclassifications typically do not materially change the underlying trends of results within each revenue category.

The following table presents the Company's net revenue by end user for the periods presented:

	First Quarters Ended
	October 1, 2021		October 2, 2020
Domestic(1)	$	189,248	$	178,743
International/Foreign Military Sales(2)	35,765		26,878
Total Net Revenue	$	225,013	$	205,621

(1) Domestic revenues consist of sales where the end user is within the U.S., as well as sales to prime defense contractor customers where the ultimate end user location is not defined. 

(2) International/Foreign Military Sales consist of sales to U.S. prime defense contractor customers where the end user is known to be outside the U.S., foreign military sales through the U.S. government, and direct sales to non-U.S. based customers intended for end use outside of the U.S.

There were no programs comprising 10% or more of the Company's revenues for the first quarters ended October 1, 2021 and October 2, 2020.

M.Commitments and Contingencies

LEGAL CLAIMS

The Company is subject to litigation, claims, investigations and audits arising from time to time in the ordinary course of its business. Although legal proceedings are inherently unpredictable, the Company believes that it has valid defenses with respect to any matters currently pending against the Company and intends to defend itself vigorously. The outcome of these matters, individually and in the aggregate, is not expected to have a material impact on the Company’s cash flows, results of operations, or financial position.

On June 23, 2021, Embedded Reps of America, LLC (“ERA”), a former sales representative, and James Mazzola, a principal of ERA, filed for binding arbitration related to the termination of ERA’s sales representative agreement raising multiple claims that aggregate to approximately $9,000 in direct damages, with treble damages requested on a number of those claims. ERA was a sales representative of Themis when Themis was acquired by Mercury. The sales representative agreement provided for termination by either party upon 30 days written notice with ERA entitled to commissions for orders obtained by ERA product shipment occurring prior to termination. The Company responded to the complaint on July 28, 2021. The Company believes the claims in the complaint are without merit and intends to defend itself vigorously.

INDEMNIFICATION OBLIGATIONS

The Company’s standard product sales and license agreements entered into in the ordinary course of business typically contain an indemnification provision pursuant to which the Company indemnifies, holds harmless, and agrees to reimburse the indemnified party for losses suffered or incurred by the indemnified party in connection with any patent, copyright or other intellectual property infringement claim by any third party with respect to the Company’s products. Such provisions generally survive termination or expiration of the agreements. The potential amount of future payments the Company could be required to make under these indemnification provisions is, in some instances, unlimited.

PURCHASE COMMITMENTS

As of October 1, 2021, the Company has entered into non-cancelable purchase commitments for certain inventory components and services used in its normal operations. The purchase commitments covered by these agreements are for less than one year and aggregate to $154,689.

OTHER

As part of the Company's strategy for growth, the Company continues to explore acquisitions or strategic alliances. The associated acquisition costs incurred in the form of professional fees and services may be material to the future periods in which they occur, regardless of whether the acquisition is ultimately completed.

20

The Company may elect from time to time to purchase and subsequently retire shares of common stock in order to settle employees’ tax liabilities associated with vesting of a restricted stock award or exercise of stock options. These transactions would be treated as a use of cash in financing activities in the Company's Consolidated Statements of Cash Flows.

N.Subsequent Events

AVALEX ACQUISITION

On September 27, 2021, the Company announced that it has signed a definitive agreement to acquire Avalex. On November 5, 2021, the Company closed its acquisition of Avalex for an all-cash purchase of $155,000 subject to net working capital and net debt adjustments. Based in Gulf Breeze, Florida. Avalex is a provider of mission-critical avionics, including rugged displays, integrated communications management systems, digital video recorders, and warning systems. Upon completion of the acquisition, Avalex will become part of the Company's Processing division. The Company has not completed its preliminary purchase price allocation for Avalex as not all information required for the analysis was available.

OVERVIEW

Mercury Systems, Inc. is a leading technology company serving the aerospace and defense industry, positioned at the intersection of high-tech and defense. Headquartered in Andover, Massachusetts, we deliver products and solutions that enable a broad range of aerospace and defense programs, optimized for mission success in some of the most challenging and demanding environments. We envision, create and deliver innovative technology solutions that are open, purpose-built and uncompromised to meet our customers’ most-pressing high-tech needs, including those specific to the defense community.

As a leading manufacturer of essential components, products, modules and subsystems, we sell to defense prime contractors, the U.S. government and OEM commercial aerospace companies. Mercury has built a trusted, contemporary portfolio of proven product solutions purpose-built for aerospace and defense that it believes meets and exceeds the performance needs of our defense and commercial customers. Customers add their own applications and algorithms to our specialized, secure and innovative products and pre-integrated solutions. This allows them to complete their full system by integrating with their platform, the sensor technology and, in some cases, the processing from Mercury. Our products and solutions are deployed in more than 300 programs with over 25 different defense prime contractors and commercial aviation customers.

Mercury’s transformational business model accelerates the process of making new technology profoundly more accessible to our customers by bridging the gap between commercial technology and aerospace and defense applications. Our long-standing deep relationships with leading high-tech companies, coupled with our high level of R&D investments and industry-leading trusted and secure design and manufacturing capabilities, are the foundational tenets of this highly successful model. We are leading the development and adaptation of commercial technology for aerospace and defense solutions. From chip-scale to system scale and from RF to digital, we make mission-critical technologies safe, secure, affordable and relevant for our customers.

Our capabilities, technology and R&D investment strategy combine to differentiate Mercury in our industry. Our technologies and capabilities include secure embedded processing modules and subsystems, mission computers, secure and rugged rack-mount servers, safety-critical avionics, components, multi-function assemblies, subsystems and custom microelectronics. We maintain our technological edge by investing in critical capabilities and IP in processing and RF, leveraging open standards and open architectures to adapt quickly those building blocks into solutions for highly data-intensive applications, including emerging needs in areas such as AI.

22

Our mission critical solutions are deployed by our customers for a variety of applications including C4ISR, electronic intelligence, avionics, EO/IR, electronic warfare, weapons and missile defense, hypersonics and radar.

Since we conduct much of our business with our defense customers via commercial items, requests by customers are a primary driver of revenue fluctuations from quarter to quarter. Customers specify delivery date requirements that coincide with their need for our products. Because these customers may use our products in connection with a variety of defense programs or other projects of different sizes and durations, a customer’s orders for one quarter generally do not indicate a trend for future orders by that customer. Additionally, order patterns do not necessarily correlate amongst customers and, therefore, we generally cannot identify sequential quarterly trends.

As of October 1, 2021, we had 2,239 employees. We employ hardware and software architects and design engineers, primarily engaged in engineering and research and product development activities to achieve our objectives to fully capitalize upon and maintain our technological leads in the high-performance, real-time sensor processing industry and in mission computing, platform management and other safety-critical applications. Our talent attraction, engagement and retention is critical to execute on our long-term strategy. We invest in our culture and values to drive employee engagement that turns ideas into action, delivering trusted and secure solutions at the speed of innovation. We believe that our success depends on our ability to embrace diversity company-wide and realize the benefits of a diverse workforce that includes a greater variety of solutions to problems, a broader collection of skills and experiences and an array of viewpoints to consider. Mercury is strongly focused on providing an inclusive environment that respects the diversity of the world. We believe that the workforce required to grow our business and deliver creative solutions must be rich in diversity of thought, experience and culture. Our diversity and inclusion initiatives focus on building and maintaining the talent that will create cohesive and collaborative teams that drive innovation. We believe that these values will help our employees realize their full potentials at work to provide Innovation That Matters®.

Our consolidated revenues, acquired revenues, net loss, diluted net loss per share, adjusted earnings per share (“adjusted EPS”), and adjusted EBITDA for the first quarter ended October 1, 2021 were $225.0 million, $41.3 million, $(7.1) million, $(0.13), $0.41, and $38.3 million, respectively. See the Non-GAAP Financial Measures section for a reconciliation to our most directly comparable GAAP financial measures.

OUR RESPONSE TO COVID

We continue to monitor the COVID pandemic and adapt our policies and programs as needed to protect the health, safety and livelihoods of our people. On September 9, 2021, President Biden signed an executive order directing executive departments and agencies to ensure that certain contracts had COVID-19 health and safety provisions, which included requirements for vaccinated employees, masking and physical distancing, and workplace safety coordinators. We are requiring all employees in the U.S. to become fully vaccinated from COVID-19 except in limited circumstances as allowed under the mandate. We are also complying with requirements for masking and physical distancing in the workplace and have maintained an internal task force to coordinate COVID-19 workplace safety efforts since the start of the pandemic.

1MPACT

On August 3, 2021, we announced a companywide effort, called 1MPACT, to lay the foundation for the next phase of the Company’s value creation at scale. The goal of 1MPACT is to achieve our full growth, margin expansion and adjusted EBITDA potential over the next five years. Since fiscal year 2014 and through the first quarter ended October 1, 2021, we have completed 13 acquisitions, deploying $1.2 billion of capital and, as a result, dramatically scaled and transformed the business. Over this time, we have extracted substantial revenue and cost synergies from each of these individual acquisitions. Now, as we approach the milestone of $1 billion of revenue, we believe there is significant opportunity to realize further scale through consolidating and streamlining our internal organizational structure which will improve visibility, speed of decision making and accountability. 1MPACT is led by our new Chief Transformation Officer, Thomas Huber, and focuses on six major areas: organization efficiency and scalability; procurement and supply chain; facilities optimization; R&D investment; capital and asset efficiency; and scalable common processes and systems.

RESULTS OF OPERATIONS:

Results of operations for the first quarter ended October 1, 2021 includes a full period of results from the acquisitions of Physical Optics Corporation ("POC") and Pentek Technologies, LLC and Pentek Systems, Inc. (collectively, "Pentek"). Results of operations for the first quarter ended October 2, 2020 do not include results from POC or Pentek. Accordingly, the periods presented below are not directly comparable.

The first quarter ended October 1, 2021 compared to the first quarter ended October 2, 2020

The following table sets forth, for the first quarter ended indicated, financial data from the Consolidated Statements of Operations and Comprehensive (Loss) Income:

(In thousands)	October 1, 2021		As a % of Total Net Revenue		October 2, 2020		As a % of Total Net Revenue
Net revenues	$	225,013	100.0	%	$	205,621	100.0	%

REVENUES

Total revenues increased $19.4 million, or 9.4%, to $225.0 million during the first quarter ended October 1, 2021, as compared to $205.6 million during the first quarter ended October 2, 2020, including “acquired revenue” which represents net revenue from acquired businesses that have been part of Mercury for completion of four full quarters or less (and excludes any intercompany transactions). After the completion of four full fiscal quarters, acquired businesses will be treated as organic for current and comparable historical periods. The increase in total revenue was primarily due to an additional $41.3 million of acquired revenues from the POC and Pentek businesses, partially offset by $21.9 million less organic revenues. These increases were driven by modules and sub-assemblies which increased $41.6 million or 238% which was partially offset by decreases in components and integrated subsystems of $15.2 million and $7.0 million, respectively. The increase in total revenue was primarily from the C4I and other sensor and effector end applications which increased $29.6 million and $8.3 million, respectively and were partially offset by a $13.5 million decrease to radar application. The increase was primarily across the airborne platform which grew $29.3 million during the first quarter ended October 1, 2021. The largest program increases were related to the MH-60 program, a classified C2 program and a classified radar program. There were no programs comprising 10% or more of our revenues for the first quarters ended October 1, 2021 or October 2, 2020. See the Non-GAAP Financial Measures section for a reconciliation to our most directly comparable GAAP financial measures.

24

GROSS MARGIN

Gross margin was 39.3% for the first quarter ended October 1, 2021, a decrease of 360 basis points from the 42.9% gross margin achieved during the first quarter ended October 2, 2020. The lower gross margin was primarily driven by program mix, including the acquisition of POC, which carries lower margins than the organic business, and higher volume of Customer Funded Research and Development (“CRAD”). CRAD primarily represents engineering labor associated with long-term contracts for customized development, production and service activities. CRAD, including POC, increased $14.5 million in the quarter. Due to the nature of these efforts, they typically carry a lower margin but serve as a precursor to higher margin production orders over time. These products are predominately grouped within integrated subsystems and to a lesser extent modules and sub-assemblies. These gross margin decreases were partially offset by $1.8 million gross margin benefit from fair value adjustments from purchase accounting and $1.7 million less COVID expenses.

SELLING, GENERAL AND ADMINISTRATIVE

Selling, general and administrative expenses increased $4.1 million, or 12.3%, to $37.0 million during the first quarter ended October 1, 2021, as compared to $32.9 million in the first quarter ended October 2, 2020. The increase was primarily related to the recent acquisitions of POC and Pentek, which contributed $3.3 million of incremental cost. Selling, general and administrative expenses increased as a percentage of revenue to 16.4% for the first quarter ended October 1, 2021 from 16.0% for the first quarter ended October 2, 2020 as a result of lower overall operating leverage in the quarter.

RESEARCH AND DEVELOPMENT

Research and development expenses increased $1.5 million, or 5.3%, to $28.9 million during the first quarter ended October 1, 2021, as compared to $27.4 million during the first quarter ended October 2, 2020. The increase was primarily related to $1.0 million of incremental expenses from the recent acquisitions of POC and Pentek as well as continued investment in internal R&D to promote future growth, including new opportunities in avionics mission computers, secure processing, radar modernization and our trusted custom microelectronics business. Research and development expenses accounted for 12.8% and 13.3% of our revenues for the first quarters ended October 1, 2021 and October 2, 2020, respectively.

AMORTIZATION OF INTANGIBLE ASSETS

Amortization of intangible assets increased $6.0 million to $13.7 million during the first quarter ended October 1, 2021, as compared to $7.7 million during the first quarter ended October 2, 2020, primarily due to the acquisitions of POC and Pentek.

RESTRUCTURING AND OTHER CHARGES

During the first quarter ended October 1, 2021, the Company incurred $12.3 million of restructuring and other charges, as compared to $1.3 million during the first quarter ended October 2, 2020. Restructuring and other charges of $7.3 million related to severance costs associated with the elimination of 100 employees based on changes in the business environment and alignment with the internal organizational changes completed under 1MPACT. The remaining $4.9 million of restructuring and other charges related to third-party consulting costs associated with 1MPACT.

ACQUISITION COSTS AND OTHER RELATED EXPENSES

Acquisition costs and other related expenses were $2.1 million during the first quarter ended October 1, 2021. The acquisition costs and other related expenses during the first quarter ended October 1, 2021 were primarily related to costs associated with signing a definitive agreement to acquire Avalex Technologies Corporation ("Avalex") and other M&A activities. We expect to incur acquisition costs and other related expenses periodically in the future as we continue to seek acquisition opportunities to expand our technological capabilities and especially within the sensor and effector and C4I markets. Transaction costs incurred by the acquiree prior to the consummation of an acquisition would not be reflected in our historical results of operations.

INTEREST INCOME

Interest income decreased to less than $0.1 million during the first quarter ended October 1, 2021, as compared to $0.1 million for the first quarter ended October 2, 2020. This was driven by lower cash on hand during the first quarter ended October 1, 2021, as compared to the prior year.

INTEREST EXPENSE

We incurred $0.6 million of interest expense during the first quarter ended October 1, 2021, related to the $200.0 million balance on our Revolver to facilitate the acquisitions of POC and Pentek during fiscal 2021.

25

OTHER EXPENSE, NET

Other expense, net increased to $1.4 million during the first quarter ended October 1, 2021, as compared to $0.8 million during the first quarter ended October 2, 2020. The first quarter ended October 1, 2021 includes net foreign currency translation losses of $0.5 million and $0.2 million less of financing and registration costs, partially offset by $0.2 million of additional litigation and settlement costs. The first quarter ended October 2, 2020 includes net foreign currency translation gains of $0.2 million.

INCOME TAXES

We recorded an income tax (benefit) provision of $(0.4) million and $2.2 million on a (loss) income before income taxes of $(7.6) million and $18.0 million for the first quarters ended October 1, 2021 and October 2, 2020, respectively.

During the first quarters ended October 1, 2021 and October 2, 2020, we recognized a discrete tax provision of $0.7 million related to stock-based compensation shortfalls and a discrete tax benefit of $2.5 million related to excess benefits on stock-based compensation, respectively.

The effective tax rate for the first quarters ended October 1, 2021 and October 2, 2020 differed from the Federal statutory rate primarily due to Federal and State research and development credits, non-deductible compensation, stock-based compensation, and state taxes. In addition, during the first quarter ended October 1, 2021, we had certain unbenefited deferred tax assets.

Within the calculation of our annual effective tax rate, we have used assumptions and estimates that may change as a result of future guidance and interpretation from the Internal Revenue Service (“IRS”).

LIQUIDITY AND CAPITAL RESOURCES

Our primary sources of liquidity come from existing cash and cash generated from operations, our Revolver and our ability to raise capital under our universal shelf registration statement. Our near-term fixed commitments for cash expenditures consist primarily of payments under operating leases and inventory purchase commitments. We plan to continue to invest in improvements to our facilities, continuous evaluation of potential acquisition opportunities and internal R&D to promote future growth, including new opportunities in avionics mission computers, secure processing, radar modernization and trusted custom microelectronics. Our facilities improvements include expansion of our trusted custom microelectronics and mission computing businesses during fiscal 2022.

Based on our current plans and business conditions, we believe that existing cash and cash equivalents, our available Revolver, cash generated from operations, and our financing capabilities will be sufficient to satisfy our anticipated cash requirements for at least the next twelve months.

Shelf Registration Statement

On September 14, 2020, we filed a shelf registration statement on Form S-3ASR with the SEC. The shelf registration statement, which was effective upon filing with the SEC, registered each of the following securities: debt securities, preferred stock, common stock, warrants and units. We intend to use the proceeds from financings using the shelf registration statement for general corporate purposes, which may include the following:

•the acquisition of other companies or businesses;

•the repayment and refinancing of debt;

•capital expenditures;

•working capital; and

•other purposes as described in the prospectus supplement.

We have an unlimited amount available under the shelf registration statement.

Revolving Credit Facility

On September 28, 2018, we amended the Revolver to increase and extend the borrowing capacity to a $750.0 million, 5-year revolving credit line, with the maturity extended to September 2023. As of October 1, 2021, we had $200.0 million of outstanding borrowings on the Revolver. See Note I in the accompanying consolidated financial statements for further discussion of the Revolver.

CASH FLOWS

	As of and For the First Quarters Ended,
(In thousands)	October 1, 2021		October 2, 2020
Net cash (used in) provided by operating activities	$	(2,006)	$	22,929
Net cash used in investing activities	$	(8,614)	$	(10,978)
Net cash used in financing activities	$	(7,316)	$	(64)
Net (decrease) increase in cash and cash equivalents	$	(18,035)	$	12,284
Cash and cash equivalents at end of period	$	95,804	$	239,122

Our cash and cash equivalents decreased by $18.0 million from July 2, 2021 to October 1, 2021, primarily as the result of the $7.3 million share repurchase and retirement of common stock used to settle individual tax liabilities, $5.4 million invested in purchases of property and equipment and $3.2 million of other investing activities.

Operating Activities

During the first quarter ended October 1, 2021, we had an outflow of $2.0 million in cash from operating activities, as compared to $22.9 million of cash generated from operating activities for the first quarter ended October 2, 2020. The decrease was primarily due to the net loss of $7.1 million, including cash outflows for restructuring and other charges associated with 1MPACT as well as acquisition costs primarily associated with the Avalex acquisition. In addition, the decrease was due to lower deferred revenue and customer advances, higher unbilled receivables and costs in excess of billings as well as income tax payments. These decreases were partially offset by lower cash outflows for accounts payable, accrued expenses and accrued compensation.

Investing Activities

During the first quarter ended October 1, 2021, we invested $8.6 million, a decrease of $2.4 million, as compared to the first quarter ended October 2, 2020. The decrease was driven by $5.6 million lower purchases of property and equipment, partially offset by $3.2 million of other investing activity during the first quarter ended October 1, 2021.

Financing Activities

During the first quarter ended October 1, 2021, we used $7.3 million of cash payments related to the purchase and retirement of common stock used to settle individual employees’ tax liabilities associated with the annual vesting of restricted stock awards, as compared to $0.1 million in the first quarter ended October 2, 2020.

COMMITMENTS, CONTRACTUAL OBLIGATIONS AND CONTINGENCIES

The following is a schedule of our commitments and contractual obligations outstanding at October 1, 2021:

(In thousands)	Total		Less Than 1 Year		1-3 Years		3-5 Years		More Than 5 Years
Purchase obligations	$	154,689	$	154,689	$	—	$	—	$	—
Operating leases	100,950		14,478		25,875		21,374		39,223
	$	255,639	$	169,167	$	25,875	$	21,374	$	39,223

Purchase obligations represent open non-cancelable purchase commitments for certain inventory components and services used in normal operations. The purchase commitments covered by these agreements are for less than one year and aggregated approximately $154.7 million at October 1, 2021.

We have a liability at October 1, 2021 of $7.5 million for uncertain tax positions that have been taken or are expected to be taken in various income tax returns. We do not know the ultimate resolution on these uncertain tax positions and as such, do not know the ultimate timing of payments or amount, if any, related to this liability. Accordingly, these amounts are not included in the above table.

Our standard product sales and license agreements entered into in the ordinary course of business typically contain an indemnification provision pursuant to which we indemnify, hold harmless, and agree to reimburse the indemnified party for losses suffered or incurred in connection with certain intellectual property infringement claims by any third party with respect to our products. Such provisions generally survive termination or expiration of the agreements. The potential amount of future payments we could be required to make under these indemnification provisions is, in some instances, unlimited.

27

As part of our strategy for growth, we continue to explore acquisitions or strategic alliances. The associated acquisition costs incurred in the form of professional fees and services may be material to the future periods in which they occur, regardless of whether the acquisition is ultimately completed.

We may elect from time to time to purchase and subsequently retire shares of common stock in order to settle employees' tax liabilities associated with vesting of a restricted stock award. These transactions are treated as a use of cash in financing activities in our Consolidated Statements of Cash Flows.

OFF-BALANCE SHEET ARRANGEMENTS

Other than certain indemnification provisions in the normal course of business, we do not have any off-balance sheet financing arrangements or liabilities, guarantee contracts, retained or contingent interests in transferred assets, or any obligation arising out of a material variable interest in an unconsolidated entity. We do not have any majority-owned subsidiaries that are not consolidated in the financial statements. Additionally, we do not have an interest in, or relationships with, any special purpose entities.

NON-GAAP FINANCIAL MEASURES

In our periodic communications, we discuss certain important measures that are not calculated according to U.S. generally accepted accounting principles (“GAAP”), including adjusted EBITDA, adjusted income, adjusted EPS, free cash flow, organic revenue and acquired revenue.

Adjusted EBITDA is defined as net income before other non-operating adjustments, interest income and expense, income taxes, depreciation, amortization of intangible assets, restructuring and other charges, impairment of long-lived assets, acquisition and financing costs, fair value adjustments from purchase accounting, litigation and settlement income and expense, COVID related expenses, and stock-based and other non-cash compensation expense. We use adjusted EBITDA as an important indicator of the operating performance of our business. We use adjusted EBITDA in internal forecasts and models when establishing internal operating budgets, supplementing the financial results and forecasts reported to our board of directors, determining the portion of bonus compensation for executive officers and other key employees based on operating performance, evaluating short-term and long-term operating trends in our operations and allocating resources to various initiatives and operational requirements. We believe that adjusted EBITDA permits a comparative assessment of our operating performance, relative to our performance based on our GAAP results, while isolating the effects of charges that may vary from period to period without any correlation to underlying operating performance. We believe that these non-GAAP financial adjustments are useful to investors because they allow investors to evaluate the effectiveness of the methodology and information used by management in our financial and operational decision-making. We believe that trends in our adjusted EBITDA are valuable indicators of our operating performance.

Adjusted EBITDA is a non-GAAP financial measure and should not be considered in isolation or as a substitute for financial information provided in accordance with GAAP. This non-GAAP financial measure may not be computed in the same manner as similarly titled measures used by other companies. We expect to continue to incur expenses similar to the adjusted EBITDA financial adjustments described above, and investors should not infer from our presentation of this non-GAAP financial measure that these costs are unusual, infrequent or non-recurring.

28

The following table reconciles our net (loss) income, the most directly comparable GAAP financial measure, to our adjusted EBITDA:

	First Quarters Ended

Interest expense (income), net	586		(72)
Income tax (benefit) provision	(441)		2,198
Depreciation	7,756		5,266

COVID related expenses	183		2,319
Stock-based and other non-cash compensation expense	9,573		7,367
Adjusted EBITDA	$	38,290	$	42,750

Adjusted income and adjusted EPS exclude the impact of certain items and, therefore, have not been calculated in accordance with GAAP. We believe that exclusion of these items assists in providing a more complete understanding of our underlying results and trends and allows for comparability with our peer company index and industry. These non-GAAP financial measures may not be computed in the same manner as similarly titled measures used by other companies. We use these measures along with the corresponding GAAP financial measures to manage our business and to evaluate our performance compared to prior periods and the marketplace. We define adjusted income as net income before other non-operating adjustments, amortization of intangible assets, restructuring and other charges, impairment of long-lived assets, acquisition and financing costs, fair value adjustments from purchase accounting, litigation and settlement income and expense, COVID related expenses, and stock-based and other non-cash compensation expense. The impact to income taxes includes the impact to the effective tax rate, current tax provision and deferred tax provision. Adjusted EPS expresses adjusted income on a per share basis using weighted average diluted shares outstanding.

Adjusted income and adjusted EPS are non-GAAP financial measures and should not be considered in isolation or as a substitute for financial information provided in accordance with GAAP. We expect to continue to incur expenses similar to the adjusted income and adjusted EPS financial adjustments described above, and investors should not infer from our presentation of these non-GAAP financial measures that these costs are unusual, infrequent or non-recurring.

Diluted weighted-average shares outstanding			55,376				55,339

(1) Impact to income taxes is calculated by recasting income before income taxes to include the add-backs involved in determining adjusted income and recalculating the income tax provision using this adjusted income from operations before income taxes. The impact to income taxes includes the impact to the effective tax rate, current tax provision and deferred tax provision.

Free cash flow, a non-GAAP measure for reporting cash flow, is defined as cash provided by operating activities less capital expenditures for property and equipment, which includes capitalized software development costs. We believe free cash flow provides investors with an important perspective on cash available for investments and acquisitions after making capital investments required to support ongoing business operations and long-term value creation. We believe that trends in our free cash flow can be valuable indicators of our operating performance and liquidity.

Free cash flow is a non-GAAP financial measure and should not be considered in isolation or as a substitute for financial information provided in accordance with GAAP. This non-GAAP financial measure may not be computed in the same manner as similarly titled measures used by other companies. We expect to continue to incur expenditures similar to the free cash flow adjustment described above, and investors should not infer from our presentation of this non-GAAP financial measure that these expenditures reflect all of our obligations which require cash.

Organic revenue and acquired revenue are non-GAAP measures for reporting the financial performance of our business. We believe this information provides investors with insight as to our ongoing business performance. Organic revenue represents total company revenue excluding net revenue from acquired companies for the first four full quarters since the entities’ acquisition date (which excludes intercompany transactions). Acquired revenue represents revenue from acquired companies for the first four full quarters since the entities' acquisition date (which excludes intercompany transactions). After the completion of four full fiscal quarters, acquired revenue is treated as organic for current and comparable historical periods.

The following tables reconcile the most directly comparable GAAP financial measure to the non-GAAP financial measure for the first quarters ended October 1, 2021 and October 2, 2020, respectively:

(In thousands)	October 1, 2021		As a % of Total Net Revenue		October 2, 2020		As a % of Total Net Revenue		$ Change		% Change

ITEM 3.     QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

There were no material changes in our exposure to market risk from July 2, 2021 to October 1, 2021.

ITEM 4.     CONTROLS AND PROCEDURES

(a) Evaluation of Disclosure Controls and Procedures

We conducted an evaluation under the supervision and with the participation of our management, including the Chief Executive Officer and Chief Financial Officer (our principal executive officer and principal financial officer, respectively), regarding the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as of the end of the period covered by this report. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures were effective as of October 1, 2021. We continue to review our disclosure controls and procedures and may from time to time make changes aimed at enhancing their effectiveness and to ensure that our systems evolve with our Company’s business. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met.

(b) Changes in Internal Control Over Financial Reporting

There was no change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the quarter ended October 1, 2021 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting. Management is in the process of integrating the POC and Pentek businesses into our overall internal control over financial reporting environment.

PART II. OTHER INFORMATION

ITEM 1.     LEGAL PROCEEDINGS

We are subject to litigation, claims, investigations and audits arising from time to time in the ordinary course of our business. Although legal proceedings are inherently unpredictable, we believe that we have valid defenses with respect to those matters currently pending against us and intend to defend our self vigorously. The outcome of these matters, individually and in the aggregate, is not expected to have a material impact on our cash flows, results of operations, or financial position.

On June 23, 2021, Embedded Reps of America, LLC (“ERA”), a former sales representative, and James Mazzola, a principal of ERA, filed for binding arbitration related to the termination of ERA’s sales representative agreement raising multiple claims that aggregate to approximately $9 million in direct damages, with treble damages requested on a number of those claims. ERA was a sales representative of Themis when Themis was acquired by Mercury. The sales representative agreement provided for termination by either party upon 30 days written notice with ERA entitled to commissions for orders obtained by ERA product shipment occurring prior to termination. We responded to the complaint on July 28, 2021. We believe the claims in the complaint are without merit and we intend to defend ourselves vigorously.

ITEM 1A.     RISK FACTORS

You should carefully review and consider the information regarding certain factors that could materially affect our business, financial condition or future results set forth under Item 1A (Risk Factors) in our Annual Report on Form 10-K for the fiscal year ended July 2, 2021. There have been no changes from the factors disclosed in our 2021 Annual Report on Form 10-K filed on August 17, 2021, although we may disclose changes to such factors from time to time in our future filings with the Securities and Exchange Commission.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

BASIS OF PRESENTATION

The accompanying consolidated financial statements have been prepared by the Company in accordance with Generally Accepted Accounting Principles (“GAAP”) in the United States of America for interim financial information and with the instructions to the Form 10-Q and Article 10 of Regulation S-X. Certain information and footnote disclosures normally included in annual consolidated financial statements have been condensed or omitted pursuant to those rules and regulations; however, in the opinion of management the financial information reflects all adjustments, consisting of adjustments of a normal recurring nature, necessary for fair presentation. These consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes for the fiscal year ended July 2, 2021 which are contained in the Company’s Annual Report on Form 10-K filed with the SEC on August 17, 2021. The results for the first quarter ended October 1, 2021 are not necessarily indicative of the results to be expected for the full fiscal year.

The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation.

All references to the first quarter of fiscal 2022 are to the quarter ended October 1, 2021. There were 13 weeks during the first quarters ended October 1, 2021 and October 2, 2020, respectively.

USE OF ESTIMATES

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates.

BUSINESS COMBINATIONS

The Company utilizes the acquisition method of accounting under ASC 805, Business Combinations, (“ASC 805”), for all transactions and events in which it obtains control over one or more other businesses, to recognize the fair value of all assets and liabilities acquired, even if less than one hundred percent ownership is acquired, and in establishing the acquisition date fair value as the measurement date for all assets and liabilities assumed. The Company also utilizes ASC 805 for the initial recognition and measurement, subsequent measurement and accounting, and disclosure of assets and liabilities arising from contingencies in business combinations.

FOREIGN CURRENCY

Local currencies are the functional currency for the Company’s subsidiaries in Switzerland, the United Kingdom, France, Japan, Spain and Canada. The accounts of foreign subsidiaries are translated using exchange rates in effect at period-end for assets and liabilities and at average exchange rates during the period for results of operations. The related translation adjustments are reported in Accumulated other comprehensive loss (“AOCL”) in shareholders’ equity. Gains (losses) resulting from non-U.S. currency transactions are included in Other expense, net in the Consolidated Statements of Operations and Comprehensive (Loss) Income and were immaterial for all periods presented.

REVENUE RECOGNITION

The Company recognizes revenue in accordance with ASC 606, Revenue from Contracts with Customers, (“ASC 606”). Revenues are derived from the sales of products that are grouped into one of the following three categories: (i) components; (ii) modules and sub-assemblies; and (iii) integrated subsystems. The Company also generates revenues from the performance of services, including systems engineering support, consulting, maintenance and other support, testing and installation. Each promised good or service within a contract is accounted for separately under the guidance of ASC 606 if they are distinct. Promised goods or services not meeting the criteria for being a distinct performance obligation are bundled into a single performance obligation with other goods or services that together meet the criteria for being distinct. The appropriate allocation of the transaction price and recognition of revenue is then determined for the bundled performance obligation.

Revenue recognized at a point in time generally relates to contracts that include a combination of components, modules and sub-assemblies, integrated subsystems and related system integration or other services. Contracts with distinct performance obligations recognized at a point in time, with or without an allocation of the transaction price, totaled 47% and 64% of revenues for the first quarters ended October 1, 2021 and October 2, 2020, respectively.

The Company also engages in long-term contracts for development, production and service activities and recognizes revenue for performance obligations over time. These long-term contracts involve the design, development, manufacture, or modification of complex modules and sub-assemblies or integrated subsystems and related services. Long-term contracts include both fixed-price and cost reimbursable contracts. The Company’s cost reimbursable contracts typically include cost-plus fixed fee and time and material contracts.

Total revenue recognized under long-term contracts over time was 53% and 36% of total revenues for the first quarters ended October 1, 2021 and October 2, 2020, respectively.

The Company generally does not provide its customers with rights of product return other than those related to assurance warranty provisions that permit repair or replacement of defective goods over a period of 12 to 36 months. The Company accrues for anticipated warranty costs upon product shipment. The Company does not consider activities related to such assurance warranties, if any, to be a separate performance obligation. The Company does offer separately priced extended warranties which generally range from 12 to 36 months that are treated as separate performance obligations. The transaction price allocated to extended warranties is recognized over time in proportion to the costs expected to be incurred in satisfying the obligations under the contract.

All revenues are reported net of government assessed taxes (e.g., sales taxes or value-added taxes). Refer to Note L for disaggregation of revenue for the period.

ACCOUNTS RECEIVABLE

Accounts receivable, net, represents amounts that have been billed and are currently due from customers. The Company maintains an allowance for credit losses to provide for the estimated amount of receivables that will not be collected. The Company provides credit to customers in the normal course of business. The Company performs ongoing credit evaluations of its customers’ financial condition and limits the amount of credit extended as necessary. The allowance is based upon an assessment of the customer's credit worthiness, reasonable forecasts about the future, history with the customer, and the age of the receivable balance. The Company typically invoices a customer upon shipment of the product (or completion of a service) for contracts where revenue is recognized at a point in time. For contracts where revenue is recognized over time, the invoicing events are typically based on specified performance obligation deliverables or milestone events, or quantifiable measures of performance.

CONTRACT BALANCES    

Contract balances result from the timing of revenue recognized, billings and cash collections, and the generation of contract assets and liabilities. Contract assets represent revenue recognized in excess of amounts invoiced to the customer and the right to payment is not subject to the passage of time. Contract assets are presented as unbilled receivables and costs in excess of billings on the Company’s Consolidated Balance Sheets. Contract liabilities consist of deferred product revenue, billings in excess of revenues, deferred service revenue, and customer advances. Deferred product revenue represents amounts that have been invoiced to customers, but are not yet recognizable as revenue because the Company has not satisfied its performance obligations under the contract. Billings in excess of revenues represents milestone billing contracts where the billings of the contract exceed recognized revenues. Deferred service revenue primarily represents amounts invoiced to customers for annual maintenance contracts or extended warranty contracts, which are recognized over time in proportion to the costs expected to be incurred in satisfying the obligations under the contract. Customer advances represent deposits received from customers on an order. Contract liabilities are included in deferred revenue and the long-term portion of deferred revenue is included within other non-current liabilities on the Company’s Consolidated Balance Sheets. Contract balances are reported in a net position on a contract-by-contract basis.

The contract asset balances were $194,367 and $162,921 as of October 1, 2021 and July 2, 2021, respectively. The contract asset balance increased due to growth in revenue recognized over time and timing of billable events under long-term contracts during the first quarter ended October 1, 2021. The contract liability balances were $29,438 and $35,201 as of October 1, 2021 and July 2, 2021, respectively. The decrease was due to lower billings in excess of revenues.

Revenue recognized for the first quarter ended October 1, 2021 that was included in the contract liability balance at July 2, 2021 was $13,137. Revenue recognized for the first quarter ended October 2, 2020 that was included in the contract liability balance at July 3, 2020 was $9,030.

REMAINING PERFORMANCE OBLIGATIONS

The Company includes in its computation of remaining performance obligations customer orders for which it has accepted signed sales orders. The definition of remaining performance obligations excludes contracts with original expected durations of less than one year, as well as those contracts that provide the customer with the right to cancel or terminate the order with no substantial penalty, even if the Company’s historical experience indicates the likelihood of cancellation or termination is remote. As of October 1, 2021, the aggregate amount of the transaction price allocated to remaining performance obligations was $373,904. The Company expects to recognize approximately 69% of its remaining performance obligations as revenue in the next 12 months and the balance thereafter.

WEIGHTED-AVERAGE SHARES

Weighted-average shares were calculated as follows:

	First Quarters Ended
	October 1, 2021	October 2, 2020
Basic weighted-average shares outstanding	55,376	54,883
Effect of dilutive equity instruments	—	456

Equity instruments to purchase 474 and 203 shares of common stock were not included in the calculation of diluted net earnings per share for the first quarters ended October 1, 2021 and October 2, 2020, respectively, because the equity instruments were anti-dilutive.

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, an amendment of the FASB Accounting Standards Codification. The amendments in this ASU provide optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. The amendments in this ASU are elective and apply to all entities, subject to meeting certain criteria, that have contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. The amendments in this Update are effective for all entities as of March 12, 2020 through December 31, 2022. The Company is currently evaluating the effect that this standard will have on its consolidated financial statements and related disclosures.

In October 2021, the FASB issued ASU No. 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, an amendment of the FASB Accounting Standards

Codification. The amendments in this ASU address diversity and inconsistency related to the recognition and measurement of contract assets and contract liabilities acquired in a business combination and require that an acquirer recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606, Revenue from Contracts with Customers. Under current U.S. GAAP, an acquirer generally recognizes assets and liabilities assumed in a business combination, including contract assets and liabilities arising from revenue contracts with customers, at fair value on the acquisition date. ASU No. 2021-08 will result in the acquirer recording acquired contract assets and liabilities on the same basis that would have been recorded by the acquiree before the acquisition under Topic 606. This ASU is effective for fiscal years beginning after December 15, 2022, with early adoption permitted, including adoption in an interim period. The Company is currently evaluating the effect that this standard will have on its consolidated financial statements and related disclosures.

RECENTLY ADOPTED ACCOUNTING PRONOUNCEMENTS

Effective July 3, 2021 the Company adopted ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, an amendment of the FASB Accounting Standards Codification. The amendments in this ASU simplify the accounting for income taxes by removing certain exceptions for intraperiod tax allocations and deferred tax liabilities for equity method investments and add guidance as to whether a step-up in tax basis of goodwill relates to a business combination or a separate transaction. This adoption did not have a material impact to the Company's consolidated financial statements or related disclosures.

PENTEK ACQUISITION

On May 27, 2021, the Company acquired Pentek Technologies, LLC and Pentek Systems, Inc. (collectively, "Pentek"). for a purchase price of $65,000, subject to net working capital and net debt adjustments. Based in Upper Saddle River, New Jersey, Pentek is a leading designer and manufacturer of ruggedized, high-performance, commercial off-the-shelf software-defined radio and data acquisition boards, recording systems and subsystems for high-end commercial and defense applications. The acquisition and associated transaction expenses were funded through a combination of cash on hand and Mercury's existing revolving credit facility (the "Revolver").

The following table presents the net purchase price and the fair values of the assets and liabilities of Pentek on a preliminary basis:

	Amounts
Consideration transferred
Cash paid at closing	$	65,668

Estimated goodwill	35,477
Estimated fair value of net assets acquired	65,668
Less cash acquired	(746)
Net purchase price	$	64,922

The amounts above represent the preliminary fair value estimates as of October 1, 2021 and are subject to subsequent adjustment as the Company obtains additional information during the measurement period and finalizes its fair value estimates. The preliminary identifiable intangible asset estimate includes customer relationships of $15,560 with a useful life of 21 years, completed technology of $6,340 with a useful life of seven years and backlog of $2,210 with a useful life of one year. Any subsequent adjustments to these fair value estimates occurring during the measurement period will result in an adjustment to goodwill.

The goodwill of $35,477 largely reflects the potential synergies and expansion of the Company's offerings across product lines and markets complementary to the Company's existing products and markets. The goodwill from this acquisition is included in the Microelectronics reporting unit. The transaction was a combination of asset and stock, with the asset portion of goodwill being deductible for tax purposes. The Company has estimated the tax value of the intangible assets from this transaction and is amortizing the amount over 15 years for tax purposes. As of October 1, 2021, the Company had $29,703 of goodwill deductible for tax purposes.

PHYSICAL OPTICS CORPORATION ACQUISITION

On December 7, 2020, the Company signed a definitive agreement to acquire Physical Optics Corporation ("POC") for a purchase price of $310,000, subject to net working capital and net debt adjustments. On December 30, 2020, the transaction closed and the Company acquired POC. Based in Torrance, California, POC expands the Company's global avionics business and its collective footprint in the platform and mission management market. The Company funded the acquisition through a combination of cash on hand and the Company's existing revolving credit facility (the "Revolver"). On May 28, 2021 the Company and representative of the former owners of POC agreed to post closing-adjustments totaling $2,641, which increased the Company’s net purchase price.

The following table presents the net purchase price and the fair values of the assets and liabilities of POC on a preliminary basis:

	Amounts

The amounts above represent the preliminary fair value estimates as of October 1, 2021 and are subject to subsequent adjustment as the Company obtains additional information during the measurement period and finalizes its fair value estimates, including the ongoing assessment of collectability of receivable balances. The preliminary identifiable intangible asset estimate includes customer relationships of $83,000 with a useful life of 11 years, completed technology of $25,000 with a useful life of 9 years and backlog of $8,000 with a useful life of one year. Any subsequent adjustments to these fair value estimates occurring during the measurement period will result in an adjustment to goodwill.

The estimated goodwill of $155,416 largely reflects the potential synergies and expansion of the Company’s offerings across product lines and markets complementary to the Company’s existing products and markets and is not deductible for tax purposes. The goodwill from this acquisition is reported in the Processing reporting unit.

AVALEX ACQUISITION

On September 27, 2021, the Company announced that it had signed a definitive agreement to acquire Avalex Technologies Corporation (“Avalex”). Based in Gulf Breeze, Florida. Avalex is a provider of mission-critical avionics, including rugged displays, integrated communications management systems, digital video recorders, and warning systems. Pursuant to the terms of the agreement, the Company will acquire Avalex for an all-cash purchase price of $155,000, subject to net working capital and net debt adjustments. On November 5, 2021, the transaction closed and the Company acquired Avalex. See Note N "Subsequent Events" to the consolidated financial statements for further discussion.

Inventory

Inventory

Inventory is stated at the lower of cost (first-in, first-out) or net realizable value, and consists of materials, labor and overhead. On a quarterly basis, the Company uses consistent methodologies to evaluate inventory for net realizable value. Once an item is written down, the value becomes the new inventory cost basis. The Company reduces the value of inventory for excess and obsolete inventory, consisting of on-hand inventory in excess of estimated usage. The excess and obsolete inventory evaluation is based upon assumptions about future demand, historical usage, product mix and possible alternative uses. Inventory was comprised of the following:

On August 3, 2021, Mercury announced a companywide effort, called 1MPACT, to lay the foundation for the next phase of the Company's value creation at scale. The goal of 1MPACT is to achieve Mercury's full growth, margin expansion and adjusted EBITDA potential over the next five years. In connection with 1MPACT, the Company realigned its internal organizational structure in the first quarter of fiscal 2022 shifting to two divisions, Processing and Microelectronics. The Mission division has now merged under the Processing division. There was no change to the Microelectronics division.

In accordance with FASB ASC 350, Intangibles-Goodwill and Other (“ASC 350”), the Company determines its reporting units based upon whether discrete financial information is available, if management regularly reviews the operating results of the component, the nature of the products offered to customers and the market characteristics of each reporting unit. A reporting unit is considered to be an operating segment or one level below an operating segment also known as a component. Component level financial information is reviewed by management across two divisions: Processing and Microelectronics. Accordingly, these were determined to be the Company's new reporting units.

The internal reorganization and change in reporting units qualified as a triggering event and required goodwill to be tested for impairment. As required by ASC 350, the Company tested goodwill for impairment immediately before and after the reorganization. As a result of these analyses, it was determined that goodwill was not impaired before or after the reorganization.

In the first quarter ended October 1, 2021, the Company assigned goodwill to the new reporting units based on the relative fair value of transferred operations.

The following table sets forth the changes in the carrying amount of goodwill for the first quarter ended October 1, 2021:

	Total
Balance at July 2, 2021	$	804,906
Goodwill adjustment for the POC acquisition	157
Goodwill adjustment for the Pentek acquisition	252
Balance at October 1, 2021	$	805,315

The Company performs its annual goodwill impairment test in the fourth quarter of each fiscal year.

The Company recorded an income tax (benefit) provision of $(441) and $2,198 on a (loss) income before income taxes of $(7,581) and $17,996 for the first quarters ended October 1, 2021 and October 2, 2020, respectively.

During the first quarters ended October 1, 2021 and October 2, 2020, the Company recognized a discrete tax provision of $715 related to stock-based compensation shortfalls and a discrete tax benefit of $2,480 related to excess benefits on stock-based compensation.

The effective tax rate for the first quarters ended October 1, 2021 and October 2, 2020 differed from the Federal statutory rate primarily due to Federal and State research and development credits, non-deductible compensation, stock-based compensation, and state taxes. In addition, during the first quarter ended October 1, 2021, the Company had certain unbenefited deferred tax assets.

During the first quarter ended October 1, 2021, there were no material changes to the Company's unrecognized tax positions.

Within the calculation of the Company's annual effective tax rate, the Company has used assumptions and estimates that may change as a result of future guidance and interpretation from the Internal Revenue Service (“IRS”).

Employee Benefit Plan

Employee Benefit Plan

PENSION PLAN

The Company maintains a defined benefit pension plan (the “Plan”) for its Swiss employees, which is administered by an independent pension fund. The Plan is mandated by Swiss law and meets the criteria for a defined benefit plan under ASC 715, Compensation—Retirement Benefits (“ASC 715”), because participants of the Plan are entitled to a defined rate of return on contributions made. The independent pension fund is a multi-employer plan with unrestricted joint liability for all participating companies for which the Plan’s overfunding or underfunding is allocated to each participating company based on an allocation key determined by the Plan.

The Company recognizes a net asset or liability for the Plan equal to the difference between the projected benefit obligation of the Plan and the fair value of the Plan’s assets as required by ASC 715. The funded status may vary from year to year due to changes in the fair value of the Plan’s assets and variations on the underlying assumptions of the projected benefit obligation of the Plan. The Plan's funded status at October 1, 2021 was a net liability of $9,691, which is recorded in Other non-current liabilities on the Consolidated Balance Sheet. The Company recorded a net gain of $48 and $31 in AOCL during the first quarters ended October 1, 2021 and October 2, 2020, respectively. The Company recognized net periodic benefit costs of $269 and $413 associated with the Plan for the first quarters ended October 1, 2021 and October 2, 2020, respectively. The Company's total expected employer contributions to the Plan during fiscal 2022 are $1,165.

STOCK INCENTIVE PLANS

At October 1, 2021, the aggregate number of shares authorized for issuance under the Company’s Amended and Restated 2018 Stock Incentive Plan (the “2018 Plan”) is 6,782 shares, including 710 shares rolled into the 2018 Plan that were available for future grant under the Company’s 2005 Stock Incentive Plan, as amended and restated (the “2005 Plan”) and 3,000 shares approved by the Company's shareholders on October 28, 2020. The 2018 Plan replaced the 2005 Plan. The shares authorized for issuance under the 2018 Plan will continue to be increased by any future cancellations, forfeitures or terminations (other than by exercise) of awards under the 2005 Plan. The foregoing does not affect any outstanding awards under the 2005 Plan, which remain in full force and effect in accordance with their terms. The 2018 Plan provides for the grant of non-qualified and incentive stock options, restricted stock, stock appreciation rights and deferred stock awards to employees and non-employees. Stock options must be granted with an exercise price of not less than 100% of the fair value of the Company’s common stock on the date of grant and the options generally have a term of seven years. There were 3,529 shares available for future grant under the 2018 Plan at October 1, 2021.

As part of the Company's ongoing annual equity grant program for employees, the Company grants performance-based restricted stock awards to certain executives and employees pursuant to the 2018 Plan. Performance awards vest based on the requisite service period subject to the achievement of specific financial performance targets. Based on the performance targets, some of these awards require graded vesting which results in more rapid expense recognition compared to traditional time-based vesting over the same vesting period. The Company monitors the probability of achieving the performance targets on a quarterly basis and may adjust periodic stock compensation expense accordingly based on its determination of the likelihood for reaching targets. The performance targets generally include the achievement of internal performance targets in relation to a peer group of companies.

EMPLOYEE STOCK PURCHASE PLAN

At October 1, 2021, the aggregate number of shares authorized for issuance under the Company’s 1997 Employee Stock Purchase Plan, as amended and restated (“ESPP”), is 2,300 shares, including 500 shares approved by the Company's shareholders on October 28, 2020. Under the ESPP, rights are granted to purchase shares of common stock at 85% of the lesser of the market value of such shares at either the beginning or the end of each six-month offering period. The ESPP permits employees to purchase common stock through payroll deductions, which may not exceed 10% of an employee’s compensation as defined in the ESPP. There were no shares issued under the ESPP during the first quarters ended October 1, 2021 and October 2, 2020, respectively. Shares available for future purchase under the ESPP totaled 428 at October 1, 2021.

Segment Reporting [Abstract]

Operating Segment, Geographic Information and Significant Customers

Operating Segment, Geographic Information and Significant Customers

Operating segments are defined as components of an enterprise evaluated regularly by the Company's Chief Operating Decision Maker ("CODM") in deciding how to allocate resources and assess performance. During the first quarter of fiscal 2022, the Company announced its 1MPACT value creation initiative to promote scale as the organization continues to grow. The Company evaluated this internal reorganization under FASB ASC 280, Segment Reporting ("ASC 280") to determine whether this change has impacted the Company's single operating and reportable segment. The Company concluded this change had no effect given the CODM continues to evaluate and manage the Company on the basis of one operating and reportable segment. The Company utilized the management approach for determining its operating segment in accordance with ASC 280.

The geographic distribution of the Company’s revenues as determined by country in which the Company's legal subsidiary is domiciled is summarized as follows:

The Company offers a broad family of products designed to meet the full range of requirements in compute-intensive, signal processing, image processing and command and control applications. To maintain a competitive advantage, the Company seeks to leverage technology investments across multiple product lines and product solutions.

The Company’s products are typically compute-intensive and require extremely high bandwidth and high throughput. These systems often must also meet significant SWaP constraints for use in aircraft, unmanned aerial vehicles, ships and other platforms and be ruggedized for use in harsh environments. The Company's products transform the massive streams of digital data created in these applications into usable information in real time. The systems can scale from a few processors to thousands of processors.

In recent years, the Company completed a series of acquisitions that changed its technological capabilities, applications and end markets. As these acquisitions and changes occurred, the Company's proportion of revenue derived from the sale of components in different technological areas, and modules, sub-assemblies and integrated subsystems which combine technologies into more complex diverse products has shifted. The following tables present revenue consistent with the Company's strategy of expanding its technological capabilities and program content. As additional information related to the Company’s products by end user, application, product grouping and/or platform is attained, the categorization of these products can vary over time. When this occurs, the Company reclassifies revenue by end user, application, product grouping and/or platform for prior periods. Such reclassifications typically do not materially change the underlying trends of results within each revenue category.

The following table presents the Company's net revenue by end user for the periods presented:

	First Quarters Ended
	October 1, 2021		October 2, 2020
Domestic(1)	$	189,248	$	178,743

Commitments and Contingencies

Commitments and Contingencies

LEGAL CLAIMS

The Company is subject to litigation, claims, investigations and audits arising from time to time in the ordinary course of its business. Although legal proceedings are inherently unpredictable, the Company believes that it has valid defenses with respect to any matters currently pending against the Company and intends to defend itself vigorously. The outcome of these matters, individually and in the aggregate, is not expected to have a material impact on the Company’s cash flows, results of operations, or financial position.

On June 23, 2021, Embedded Reps of America, LLC (“ERA”), a former sales representative, and James Mazzola, a principal of ERA, filed for binding arbitration related to the termination of ERA’s sales representative agreement raising multiple claims that aggregate to approximately $9,000 in direct damages, with treble damages requested on a number of those claims. ERA was a sales representative of Themis when Themis was acquired by Mercury. The sales representative agreement provided for termination by either party upon 30 days written notice with ERA entitled to commissions for orders obtained by ERA product shipment occurring prior to termination. The Company responded to the complaint on July 28, 2021. The Company believes the claims in the complaint are without merit and intends to defend itself vigorously.

INDEMNIFICATION OBLIGATIONS

The Company’s standard product sales and license agreements entered into in the ordinary course of business typically contain an indemnification provision pursuant to which the Company indemnifies, holds harmless, and agrees to reimburse the indemnified party for losses suffered or incurred by the indemnified party in connection with any patent, copyright or other intellectual property infringement claim by any third party with respect to the Company’s products. Such provisions generally survive termination or expiration of the agreements. The potential amount of future payments the Company could be required to make under these indemnification provisions is, in some instances, unlimited.

PURCHASE COMMITMENTS

As of October 1, 2021, the Company has entered into non-cancelable purchase commitments for certain inventory components and services used in its normal operations. The purchase commitments covered by these agreements are for less than one year and aggregate to $154,689.

OTHER

As part of the Company's strategy for growth, the Company continues to explore acquisitions or strategic alliances. The associated acquisition costs incurred in the form of professional fees and services may be material to the future periods in which they occur, regardless of whether the acquisition is ultimately completed.

The Company may elect from time to time to purchase and subsequently retire shares of common stock in order to settle employees’ tax liabilities associated with vesting of a restricted stock award or exercise of stock options. These transactions would be treated as a use of cash in financing activities in the Company's Consolidated Statements of Cash Flows.

Summary of Significant Accounting Policies (Policies)

3 Months Ended

Oct. 01, 2021

Accounting Policies [Abstract]

Basis of Presentation

BASIS OF PRESENTATION

The accompanying consolidated financial statements have been prepared by the Company in accordance with Generally Accepted Accounting Principles (“GAAP”) in the United States of America for interim financial information and with the instructions to the Form 10-Q and Article 10 of Regulation S-X. Certain information and footnote disclosures normally included in annual consolidated financial statements have been condensed or omitted pursuant to those rules and regulations; however, in the opinion of management the financial information reflects all adjustments, consisting of adjustments of a normal recurring nature, necessary for fair presentation. These consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes for the fiscal year ended July 2, 2021 which are contained in the Company’s Annual Report on Form 10-K filed with the SEC on August 17, 2021. The results for the first quarter ended October 1, 2021 are not necessarily indicative of the results to be expected for the full fiscal year.

The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation

Use of Estimates

USE OF ESTIMATES

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates.

Business Combinations

BUSINESS COMBINATIONS

The Company utilizes the acquisition method of accounting under ASC 805, Business Combinations, (“ASC 805”), for all transactions and events in which it obtains control over one or more other businesses, to recognize the fair value of all assets and liabilities acquired, even if less than one hundred percent ownership is acquired, and in establishing the acquisition date fair value as the measurement date for all assets and liabilities assumed. The Company also utilizes ASC 805 for the initial recognition and measurement, subsequent measurement and accounting, and disclosure of assets and liabilities arising from contingencies in business combinations.

Foreign Currency

FOREIGN CURRENCY

Local currencies are the functional currency for the Company’s subsidiaries in Switzerland, the United Kingdom, France, Japan, Spain and Canada. The accounts of foreign subsidiaries are translated using exchange rates in effect at period-end for assets and liabilities and at average exchange rates during the period for results of operations. The related translation adjustments are reported in Accumulated other comprehensive loss (“AOCL”) in shareholders’ equity. Gains (losses) resulting from non-U.S. currency transactions are included in Other expense, net in the Consolidated Statements of Operations and Comprehensive (Loss) Income and were immaterial for all periods presented.

Revenue Recognition

REVENUE RECOGNITION

The Company recognizes revenue in accordance with ASC 606, Revenue from Contracts with Customers, (“ASC 606”). Revenues are derived from the sales of products that are grouped into one of the following three categories: (i) components; (ii) modules and sub-assemblies; and (iii) integrated subsystems. The Company also generates revenues from the performance of services, including systems engineering support, consulting, maintenance and other support, testing and installation. Each promised good or service within a contract is accounted for separately under the guidance of ASC 606 if they are distinct. Promised goods or services not meeting the criteria for being a distinct performance obligation are bundled into a single performance obligation with other goods or services that together meet the criteria for being distinct. The appropriate allocation of the transaction price and recognition of revenue is then determined for the bundled performance obligation.

Revenue recognized at a point in time generally relates to contracts that include a combination of components, modules and sub-assemblies, integrated subsystems and related system integration or other services. Contracts with distinct performance obligations recognized at a point in time, with or without an allocation of the transaction price, totaled 47% and 64% of revenues for the first quarters ended October 1, 2021 and October 2, 2020, respectively.

The Company also engages in long-term contracts for development, production and service activities and recognizes revenue for performance obligations over time. These long-term contracts involve the design, development, manufacture, or modification of complex modules and sub-assemblies or integrated subsystems and related services. Long-term contracts include both fixed-price and cost reimbursable contracts. The Company’s cost reimbursable contracts typically include cost-plus fixed fee and time and material contracts.

Total revenue recognized under long-term contracts over time was 53% and 36% of total revenues for the first quarters ended October 1, 2021 and October 2, 2020, respectively.

The Company generally does not provide its customers with rights of product return other than those related to assurance warranty provisions that permit repair or replacement of defective goods over a period of 12 to 36 months. The Company accrues for anticipated warranty costs upon product shipment. The Company does not consider activities related to such assurance warranties, if any, to be a separate performance obligation. The Company does offer separately priced extended warranties which generally range from 12 to 36 months that are treated as separate performance obligations. The transaction price allocated to extended warranties is recognized over time in proportion to the costs expected to be incurred in satisfying the obligations under the contract.

All revenues are reported net of government assessed taxes (e.g., sales taxes or value-added taxes). Refer to Note L for disaggregation of revenue for the period.

Contract balances result from the timing of revenue recognized, billings and cash collections, and the generation of contract assets and liabilities. Contract assets represent revenue recognized in excess of amounts invoiced to the customer and the right to payment is not subject to the passage of time. Contract assets are presented as unbilled receivables and costs in excess of billings on the Company’s Consolidated Balance Sheets. Contract liabilities consist of deferred product revenue, billings in excess of revenues, deferred service revenue, and customer advances. Deferred product revenue represents amounts that have been invoiced to customers, but are not yet recognizable as revenue because the Company has not satisfied its performance obligations under the contract. Billings in excess of revenues represents milestone billing contracts where the billings of the contract exceed recognized revenues. Deferred service revenue primarily represents amounts invoiced to customers for annual maintenance contracts or extended warranty contracts, which are recognized over time in proportion to the costs expected to be incurred in satisfying the obligations under the contract. Customer advances represent deposits received from customers on an order. Contract liabilities are included in deferred revenue and the long-term portion of deferred revenue is included within other non-current liabilities on the Company’s Consolidated Balance Sheets. Contract balances are reported in a net position on a contract-by-contract basis.

Accounts Receivables

ACCOUNTS RECEIVABLEAccounts receivable, net, represents amounts that have been billed and are currently due from customers. The Company maintains an allowance for credit losses to provide for the estimated amount of receivables that will not be collected. The Company provides credit to customers in the normal course of business. The Company performs ongoing credit evaluations of its customers’ financial condition and limits the amount of credit extended as necessary. The allowance is based upon an assessment of the customer's credit worthiness, reasonable forecasts about the future, history with the customer, and the age of the receivable balance. The Company typically invoices a customer upon shipment of the product (or completion of a service) for contracts where revenue is recognized at a point in time. For contracts where revenue is recognized over time, the invoicing events are typically based on specified performance obligation deliverables or milestone events, or quantifiable measures of performance.

Weighted-Average Shares

WEIGHTED-AVERAGE SHARES

Weighted-average shares were calculated as follows:

	First Quarters Ended
	October 1, 2021	October 2, 2020
Basic weighted-average shares outstanding	55,376	54,883
Effect of dilutive equity instruments	—	456
Diluted weighted-average shares outstanding	55,376	55,339

Equity instruments to purchase 474 and 203 shares of common stock were not included in the calculation of diluted net earnings per share for the first quarters ended October 1, 2021 and October 2, 2020, respectively, because the equity instruments were anti-dilutive.

Recently Adopted Accounting Pronouncements

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, an amendment of the FASB Accounting Standards Codification. The amendments in this ASU provide optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. The amendments in this ASU are elective and apply to all entities, subject to meeting certain criteria, that have contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. The amendments in this Update are effective for all entities as of March 12, 2020 through December 31, 2022. The Company is currently evaluating the effect that this standard will have on its consolidated financial statements and related disclosures.

In October 2021, the FASB issued ASU No. 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, an amendment of the FASB Accounting Standards

Codification. The amendments in this ASU address diversity and inconsistency related to the recognition and measurement of contract assets and contract liabilities acquired in a business combination and require that an acquirer recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606, Revenue from Contracts with Customers. Under current U.S. GAAP, an acquirer generally recognizes assets and liabilities assumed in a business combination, including contract assets and liabilities arising from revenue contracts with customers, at fair value on the acquisition date. ASU No. 2021-08 will result in the acquirer recording acquired contract assets and liabilities on the same basis that would have been recorded by the acquiree before the acquisition under Topic 606. This ASU is effective for fiscal years beginning after December 15, 2022, with early adoption permitted, including adoption in an interim period. The Company is currently evaluating the effect that this standard will have on its consolidated financial statements and related disclosures.

RECENTLY ADOPTED ACCOUNTING PRONOUNCEMENTS

Effective July 3, 2021 the Company adopted ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, an amendment of the FASB Accounting Standards Codification. The amendments in this ASU simplify the accounting for income taxes by removing certain exceptions for intraperiod tax allocations and deferred tax liabilities for equity method investments and add guidance as to whether a step-up in tax basis of goodwill relates to a business combination or a separate transaction. This adoption did not have a material impact to the Company's consolidated financial statements or related disclosures.

Stock-Based Compensation

STOCK INCENTIVE PLANS

At October 1, 2021, the aggregate number of shares authorized for issuance under the Company’s Amended and Restated 2018 Stock Incentive Plan (the “2018 Plan”) is 6,782 shares, including 710 shares rolled into the 2018 Plan that were available for future grant under the Company’s 2005 Stock Incentive Plan, as amended and restated (the “2005 Plan”) and 3,000 shares approved by the Company's shareholders on October 28, 2020. The 2018 Plan replaced the 2005 Plan. The shares authorized for issuance under the 2018 Plan will continue to be increased by any future cancellations, forfeitures or terminations (other than by exercise) of awards under the 2005 Plan. The foregoing does not affect any outstanding awards under the 2005 Plan, which remain in full force and effect in accordance with their terms. The 2018 Plan provides for the grant of non-qualified and incentive stock options, restricted stock, stock appreciation rights and deferred stock awards to employees and non-employees. Stock options must be granted with an exercise price of not less than 100% of the fair value of the Company’s common stock on the date of grant and the options generally have a term of seven years. There were 3,529 shares available for future grant under the 2018 Plan at October 1, 2021.

As part of the Company's ongoing annual equity grant program for employees, the Company grants performance-based restricted stock awards to certain executives and employees pursuant to the 2018 Plan. Performance awards vest based on the requisite service period subject to the achievement of specific financial performance targets. Based on the performance targets, some of these awards require graded vesting which results in more rapid expense recognition compared to traditional time-based vesting over the same vesting period. The Company monitors the probability of achieving the performance targets on a quarterly basis and may adjust periodic stock compensation expense accordingly based on its determination of the likelihood for reaching targets. The performance targets generally include the achievement of internal performance targets in relation to a peer group of companies.

EMPLOYEE STOCK PURCHASE PLAN

At October 1, 2021, the aggregate number of shares authorized for issuance under the Company’s 1997 Employee Stock Purchase Plan, as amended and restated (“ESPP”), is 2,300 shares, including 500 shares approved by the Company's shareholders on October 28, 2020. Under the ESPP, rights are granted to purchase shares of common stock at 85% of the lesser of the market value of such shares at either the beginning or the end of each six-month offering period. The ESPP permits employees to purchase common stock through payroll deductions, which may not exceed 10% of an employee’s compensation as defined in the ESPP. There were no shares issued under the ESPP during the first quarters ended October 1, 2021 and October 2, 2020, respectively. Shares available for future purchase under the ESPP totaled 428 at October 1, 2021.
