NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Amounts in thousands except per share data)

(Unaudited)

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 June 28, 2024, which are contained in the Company’s Annual Report on Form 10-K filed with the SEC on August 13, 2024. The results for the first quarter ended September 27, 2024 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 2025 are to the quarter ended September 27, 2024. There were 13 weeks during the first quarters ended September 27, 2024 and September 29, 2023, 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.

FOREIGN CURRENCY

Local currencies are the functional currency for the Company’s subsidiaries in Switzerland, the United Kingdom, 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 income (“AOCI”) 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 and were immaterial for all periods presented.

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.

ACCOUNTS RECEIVABLES FACTORING

On September 27, 2022, the Company executed an uncommitted receivables purchase agreement (“RPA”), pursuant to which the Company may offer to sell certain customer receivables, subject to the terms and conditions of the RPA. The RPA is an uncommitted arrangement such that the Company is not obligated to sell any receivables and the party has no obligation to purchase any receivables from the Company. Pursuant to the RPA, the party may purchase certain of the Company's customer receivables at a discounted rate, subject to a limit that as of any date, the total amount of purchased receivables held by the party, less the amount of all collections received on such receivables, may not exceed $20,000. The RPA has an indefinite term and the agreement remains in effect until it is terminated by either party. Factoring under the RPA Agreement is treated as a true sale of accounts receivable by the Company. The Company has continued involvement in servicing accounts receivable under the RPA, but no retained interests related to the factored accounts receivable. On March 14, 2023, the Company amended the RPA to increase the capacity from $20,000 to $30,600. On June 21, 2023, the Company further amended the RPA to increase the capacity from $30,600 to $60,000. On August 13, 2024, the Company terminated the RPA in conjunction with entering into a new receivables purchase and service agreement.

On August 13, 2024, the Company entered into a $60,000 committed receivables purchase and servicing agreement (“RPSA”) with a new party. The RPSA has an initial term of two years. Pursuant to the RPSA, the new party has committed to purchase receivables from a certain number of agreed upon customers, maintaining a balance of purchased receivables at or below $60,000. Under the RPSA, a portion of the factored receivables is paid by the counterparty in cash and classified as a deferred purchase price receivable, which is paid as receivables are collected by the Company.

Proceeds for amounts factored by the Company are recorded as an increase to cash and a reduction to accounts receivable outstanding in the Consolidated Balance Sheets. Cash Flows attributable to factored receivables are reflected as cash flows from operating activities in the Company's Consolidated Statements of Cash Flows. Factoring fees are included as selling, general and administrative expenses in the Company's Consolidated Statements of Operations and Comprehensive Loss.

The Company had $43,659 and $362 of factored accounts receivables and factoring fees, respectively, for the first quarter ended September 27, 2024. At September 27, 2024, the Company had $18,835 of factored receivables included in Accounts receivable, net allowance for credit losses on Consolidated Balance Sheet. The Company had $28,826 and $308 of factored accounts receivables and factoring fees, respectively, for the first quarter ended September 29, 2023.

DERIVATIVES

The Company records the fair value of its derivative financial instruments in its consolidated financial statements in Other non-current assets, or Other non-current liabilities depending on their net position, regardless of the purpose or intent for holding the derivative contract. Changes in the fair value of the derivative financial instruments are either recognized periodically in earnings or in shareholders’ equity as a component of Other comprehensive income (loss) (“OCI”). Changes in the fair value of cash flow hedges that qualify for hedge accounting treatment are recorded in OCI and reclassified into earnings in the same line item on the Consolidated Statements of Operations and Comprehensive Loss as the impact of the hedged transaction when the underlying contract matures and, for interest rate exposure derivatives, over the term of the corresponding debt instrument. Changes in the fair values of derivatives not qualifying for hedge accounting are reported in earnings as they occur. All derivatives for the Company qualified for hedge accounting as of September 27, 2024.

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 solutions. 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 solutions 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 45% and 42% of revenues for the first quarters ended September 27, 2024 and September 29, 2023, respectively.

The Company also engages in contracts for development, production and service activities and recognizes revenue for performance obligations over time. These over time contracts involve the design, development, manufacture, or modification of complex modules and sub-assemblies or integrated solutions and related services. Over time 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.

Accounting for contracts recognized over time requires significant judgment relative to estimating total contract revenues and costs. In particular, this includes assumptions relative to the amount of time to complete the contract and the assessment of the nature and complexity of the work to be performed and the impact of contract amendments which may result in cumulative adjustments. The Company's estimates are based upon the professional knowledge and experience of its engineers, operations, program managers and other personnel, who review each over time contract monthly to assess the contract’s schedule, performance, technical matters and estimated cost at completion. Changes in estimates are applied retrospectively and when adjustments in estimated contract costs are identified, such revisions may result in current period adjustments to earnings applicable to performance in prior periods. The aggregate effects of these favorable and unfavorable changes across the Company’s portfolio of programs can have a significant effect upon its reported Loss from operations, Net loss and Diluted net loss per share in each of the reporting periods. The net impact of changes in estimates had the following impact on the Company’s operating results:


	First Quarters Ended
(In thousands, except per share data)	September 27, 2024		September 29, 2023
Loss from operations	$	(8,293)	$	(16,463)
Net loss (1)	$	(6,054)	$	(12,018)
Diluted net loss per share	$	(0.10)	$	(0.21)
Diluted Shares	58,260		57,105
(1) Federal and state statutory rate of 27%

Total revenue recognized over time was 55% and 58% of total revenues for the first quarters ended September 27, 2024 and September 29, 2023, 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 generally 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.

The Company's contracts generally do not include significant financing components. The Company's over time contracts may include milestone payments, which align the payment schedule with the progress towards completion on the performance obligation. Otherwise, the Company's contracts are predicated on payment upon completion of the performance obligation. On certain contracts, the Company may be entitled to receive an advance payment, which is not considered a significant financing component because most contracts have a duration of approximately two years on average and it is used to facilitate inventory demands at the onset of a contract and to safeguard the Company from the failure of the other party to abide by some or all of their obligations under the contract.

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

CONTRACT BALANCES

Contract balances result from the timing of revenue recognized, billings and cash collections resulting in 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. Instead, while the Company has an enforceable right to payment as progress is made over performance obligations, billings to customers are generally predicated on (i) completion of defined milestones, (ii) monthly costs incurred or (iii) final delivery of goods or services. Contract assets are presented as Unbilled receivables and costs in excess of billings, net of allowance for credit losses 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 as well as 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 $298,270 and $304,029 as of September 27, 2024 and June 28, 2024, respectively. The contract asset balance decreased due to $117,865 of billings, offset by revenue recognized under over time contracts of $112,106 during the first quarter ended September 27, 2024. The contract liability balances were $96,859 and $74,367 as of September 27, 2024 and June 28, 2024, respectively. The contract liability increased due to a higher volume of milestone billing events as well as timing of revenue recognized across multiple programs.

Revenue recognized for the first quarter ended September 27, 2024 that was included in the contract liability balance at June 28, 2024 was $26,411. Revenue recognized for the first quarter ended September 29, 2023 that was included in the contract liability balance at June 30, 2023 was $21,015.

REMAINING PERFORMANCE OBLIGATIONS

The Company includes in its computation of remaining performance obligations customer orders for which it has accepted executed 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 September 27, 2024, the aggregate amount of the transaction price allocated to remaining performance obligations was $765,775. The Company expects to recognize approximately 54% of its remaining performance obligations as revenue in the next 12 months and the balance thereafter.

LONG-LIVED ASSETS

Long-lived assets primarily include property and equipment, intangible assets and right-of-use ("ROU") assets. The Company regularly evaluates its long-lived assets for events and circumstances that indicate a potential impairment in accordance with ASC 360, Property, Plant and Equipment (“ASC 360”). The Company reviews long-lived assets for impairment whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable or that the useful lives of these assets are no longer appropriate. Each impairment test is based on a comparison of the estimated undiscounted cash flows of the asset as compared to the recorded value of the asset. If impairment is indicated, the asset is written down to its estimated fair value.

GOODWILL AND INTANGIBLE ASSETS

Goodwill is the amount by which the purchase price of a business acquisition exceeded the fair values of the net identifiable assets on the date of purchase (see Note E). In accordance with the requirements of Intangibles-Goodwill and Other (“ASC 350”), goodwill is not amortized. Goodwill is assessed for impairment at least annually, on a reporting unit basis, or when events and circumstances (“triggering event”) occur indicating that the recorded goodwill may be impaired. Potential triggering events include macroeconomic conditions, industry and market considerations, financial performance and expectations of projected financial performance and cash flows, and changes in the Company's stock price in relation to the carrying value of its reporting units, among other relevant factors. Adverse changes to these events and circumstances could require the Company to perform an interim impairment test.

Intangible assets result from the Company’s various business acquisitions and certain licensed technologies, and consist of identifiable intangible assets, including completed technology, licensing agreements, patents, customer relationships, trademarks, backlog and non-compete agreements. Intangible assets are reported at cost, net of accumulated amortization and

are either amortized on a straight-line basis over their estimated useful lives of up to 12.5 years or over the period the economic benefits of the intangible asset are consumed.

PRODUCT WARRANTY ACCRUAL

The Company’s product sales generally include a 12 to 36 month standard hardware warranty. At time of product shipment, the Company accrues for the estimated cost to repair or replace potentially defective products. Estimated warranty costs are based upon prior actual warranty costs for substantially similar transactions and any specifically identified warranty requirements. Product warranty accrual is included as part of accrued expenses in the accompanying Consolidated Balance Sheets. The following table presents the changes in the Company's product warranty accrual.


	Total
Balance at June 28, 2024	$	5,721
Accruals for warranties issued during the period	97
Settlements made during the period	(998)
Balance at September 27, 2024	$	4,820

WEIGHTED-AVERAGE SHARES

Weighted-average shares were calculated as follows:


	First Quarters Ended
	September 27, 2024	September 29, 2023
Basic weighted-average shares outstanding	58,260	57,105
Effect of dilutive equity instruments	—	—
Diluted weighted-average shares outstanding	58,260	57,105

Equity instruments to purchase 2,694 and 1,912 shares of common stock were not included in the calculation of diluted net loss per share for the first quarters ended September 27, 2024 and September 29, 2023, respectively, because the equity instruments were anti-dilutive.

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

C.Fair Value of Financial Instruments

The following table summarizes the Companies' financial instruments measured at fair value on a recurring basis as of September 27, 2024:


	Fair Value Measurements
	September 27, 2024		Level 1		Level 2		Level 3
Liabilities:



Interest rate swap	$	9,628	$	—	$	9,628	$	—

Total	$	9,628	$	—	$	9,628	$	—

The carrying values of cash and cash equivalents, including money market funds, restricted cash, accounts receivable and payable, contract assets and liabilities 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.

During the first quarter ended September 29, 2023, the Company entered into an interest rate hedging agreement (the “September 2023 Swap”). The fair value of the September 2023 Swap is estimated using a discounted cash flow analysis based on the contractual terms of the derivative, leveraging observable inputs other than quoted prices, such as interest rates. As of September 27, 2024, the fair value of the September 2023 Swap was a liability of $9,628 and is included within Other non-current liabilities in the Company's Consolidated Balance Sheets. As of June 28, 2024, the fair value of the September 2023 Swap was a liability of $2,436 and was included within Other non-current liabilities in the Company's Consolidated Balance Sheets.

The following table summarizes the Companies' financial instruments measured at fair value on a recurring basis as of June 28, 2024:


	Fair Value Measurements
	June 28, 2024		Level 1		Level 2		Level 3
Liabilities:
Interest rate swap	$	2,436	$	—	$	2,436	$	—
Total assets measured at fair value	$	2,436	$	—	$	2,436	$	—

The fair value of the September 2023 Swap is estimated using a discounted cash flow analysis based on the contractual terms of the derivative, leveraging observable inputs other than quoted prices, such as interest rates.

Refer to Note M for further information regarding the September 2023 Swap.

D. 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
		September 27, 2024		June 28, 2024
Raw materials		$	206,986	$	200,501
Work in process		124,321		118,060
Finished goods		19,781		16,739
Total		$	351,088	$	335,300

E.Goodwill

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: Mission Systems and Microelectronics. Accordingly, these were determined to be the Company's reporting units.

The Company performs its annual goodwill impairment test in the fourth quarter of each fiscal year. The Company estimates its fair value and compares the fair value with the carrying value of its reporting units, including goodwill using an income approach based upon a discounted cash flow (“DCF”) model to calculate the present value of cash flows to estimate its implied fair value. The future cash flows for the Company’s reporting units are projected based on the Company’s estimates, at that time, of future revenues, expenses, capital expenditures, and working capital. The discount rates used in the Company’s DCF model were based on a weighted-average cost of capital (“WACC”) determined from relevant market comparisons, adjusted upward for specific reporting unit risks (primarily the uncertainty of achieving projected operating cash flows). A terminal value growth rate is applied to the final year of the projected period, which reflects the Company’s estimate of stable, perpetual growth. The Company then calculated a present value of the respective cash flows for each reporting unit to arrive at an estimate of fair value under the income approach. In addition, the Company uses the market approach, which compares the reporting unit to publicly traded companies and transactions involving similar businesses, to support the conclusions of the income approach. Finally, the Company compared its estimates of fair values to its total market capitalization to assess the reasonableness of the reporting units combined determined fair value.

The Company also assesses potential triggering events during interim reporting periods. During the first quarter ended September 27, 2024, the Company assessed events and circumstances to consider its reporting units for a potential triggering event, including: macroeconomic conditions, industry and market considerations, financial performance and expectations of projected financial performance and cash flows, changes in the Company's stock price in relation to the carrying value of its reporting units, among other relevant factors. The Company concluded that there were no triggering events during the period that would require an interim impairment test.

F.Restructuring

During the first quarter ended September 27, 2024, the Company incurred $2,260 of severance costs. The Company incurs restructuring and other charges in connection with management's decision to undertake certain actions to realign operating expenses through workforce reductions and the closure of certain Company facilities, businesses and product lines. All of the restructuring and other charges are classified as Operating expenses in the Consolidated Statements of Operations and Comprehensive Loss and any remaining restructuring 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 charges included in the Company’s liability for restructuring and other charges:


	Severance & Related
Balance at June 28, 2024	$	8,758
Restructuring charges	2,260

Cash paid	(6,185)

Balance at September 27, 2024	$	4,833

G.Income Taxes

The Company recorded an income tax benefit of $5,594 and $13,027 on a loss before income taxes of $23,119 and $49,735 for the first quarters ended September 27, 2024 and September 29, 2023, respectively.

During the first quarters ended September 27, 2024 and September 29, 2023, the Company recognized a tax provision of $219 and $1,215 related to stock compensation shortfalls, respectively.

The effective tax rate for the first quarter ended September 27, 2024 differed from the federal statutory rate primarily due to federal and state research and development credits, non-deductible compensation and state taxes. The effective tax rate for the first quarter ended September 29, 2023 differed from the federal statutory rate primarily due to federal and state research and development credits and state taxes.

The Company continues to maintain a valuation allowance on the majority of its foreign net operating loss carryforwards and state research and developmental tax credit carryforwards. Based on forecasted taxable income and the scheduled reversal of the remaining deferred tax assets, the Company believes it is more likely than not that all other deferred tax assets will be recognized.

H.Debt

REVOLVING CREDIT FACILITY

The Company maintains a 5-year revolving credit facility (the "Revolver") with a maturity extended to February 28, 2027. As of September 27, 2024, the Company's outstanding balance of unamortized deferred financing costs was $5,108, which is being amortized to Other expense, net in the Consolidated Statements of Operations and Comprehensive Loss on a straight line basis over the term of the Revolver and includes the costs incurred in conjunction with the August 2024 amendment to the Revolver.

On November 7, 2023, due to the uncertainty surrounding a government shutdown or prolonged continuing resolution and the potential impact on the second quarter and fiscal 2024 results, the Company proactively executed Amendment No. 5 to the Revolver, as amended to date, with a syndicate of commercial banks and Bank of America, N.A acting as the administrative agent allowing for a temporary increase in the Consolidated Total Net Leverage Ratio covenant requirement from 4.50 to 5.25 for the second quarter ended December 29, 2023. In conjunction with Amendment No. 5 to the Revolver, the Company incurred $1,931 of new deferred financing costs that will be amortized over the remaining term of the Revolver. Refer to exhibit 10.1 on Form 8-K filed by the Company with the SEC on November 7, 2023.

On August 13, 2024, the Company executed Amendment No. 6 to the Revolver, decreasing the permanent borrowing capacity to $900,000, with a temporary reduction in credit availability to $750,000 until the Company meets a minimum consolidated EBITDA level, as defined in the Amendment No. 6 to the Revolver. In conjunction with Amendment No. 6 to the Revolver, the Company incurred $2,249 of new deferred financing costs that will be amortized over the remaining term of the Revolver. As part of the amendment, the Company wrote off $714 of previously deferred financing costs associated with the line of credit facility prior to the amendment. This write-off is included in Other expense, net in the Consolidated Statements of Operations and Comprehensive Loss. Refer to exhibit 10.7.6 on Form 10-K filed by the Company with the SEC on August 13, 2024.

During the first quarter ended September 27, 2024, the Company made no additional borrowings. As of September 27, 2024, the Company was in compliance with all covenants and conditions under the Revolver and there were outstanding borrowings of $591,500 against the Revolver, resulting in interest expense of $8,906 for the first quarter ended September 27, 2024. The borrowing capacity as defined under the Revolver as of September 27, 2024 is approximately $750,000 less outstanding borrowings of $591,500. There were outstanding letters of credit of $753 as of September 27, 2024.

I.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 September 27, 2024 was a net liability of $5,383, which is recorded in Other non-current liabilities on the Consolidated Balance Sheet. The Company recognized net periodic benefit costs of $232 and $207 associated with the Plan and a net loss of $54 and $56 in AOCI during the first quarters ended September 27, 2024 and September 29, 2023, respectively. The Company's total expected employer contributions to the Plan during fiscal 2025 are $959.

401(k) Plan

The Company maintains a qualified 401(k) plan (the “401(k) Plan”) for its U.S. employees and matches participants' contributions to the plan of up to 6% of their eligible annual compensation in Company stock. The Company may also make optional contributions to the plan for any plan year at its discretion. The Company had $2,981 and $2,901 of capitalized stock-based 401(k) matching compensation expense on the Consolidated Balance Sheets at September 27, 2024 and June 28, 2024, respectively. Stock-based 401(k) matching compensation cost is measured based on the value of the matching amount and is recognized as expense as incurred. During the first quarter ended September 27, 2024, the Company recognized share-based matching contributions related to the 401(k) plan of $4,432, as compared to $4,841 during the first quarter ended September 29, 2023.

Deferred Compensation Plan

The Company implemented a nonqualified deferred compensation plan as of January 1, 2024, under which eligible employees may defer up to 50% of their base salaries and up to 100% of their annual incentive bonuses. The Company may also make employer contributions to participant accounts in its sole discretion, and for calendar year 2024, will match participants’ deferrals under the plan of up to 6% of their eligible annual compensation in the form of deferred stock units (or at the Company’s election, a cash deferral credited to participants’ account balances). The Company’s matching obligation for 2024 is subject to the satisfaction of a financial performance condition for the Company's four fiscal quarters corresponding to the 2024 calendar year. Participant deferrals under the plan are held in a Rabbi trust and are subject to the claims of the Company’s creditors. Assets held by the rabbi trust are classified as trading securities and are recorded at fair value, with changes in value recorded as adjustments to other income. All deferrals or employer contributions under the plan, and all earnings thereon, are fully vested as and when made or credited to plan participants.

As of September 27, 2024, the Company held assets under the rabbi trust of $183, and was subject to liabilities for amounts payable under the plan to participants (including accrued employer matching contributions not yet credited to plan participants) of $183. Assets related to this plan are included in Other assets, and liabilities related to this plan are included in Other long-term liabilities in the Consolidated Balance Sheets. During the first quarter ended September 27, 2024, the Company recognized an immaterial value of compensation expense as a result of changes in the value of notional investments selected by plan participants for the investment of their plan account balances, with the same amount being recorded as other income attributable to changes in the market value of the assets held by the Rabbi trust. The nonqualified deferred compensation plan was not in place as of the first quarter ended September 29, 2023.

J.Stock-Based Compensation

STOCK INCENTIVE PLANS

At September 27, 2024, the aggregate number of shares authorized for issuance under the Company’s Amended and Restated 2018 Stock Incentive Plan (the “2018 Plan”) is 7,862 shares, including 3,000 shares approved by the Company's shareholders on October 28, 2020 and 2,000 shares approved for future grant under the 2018 Plan by the Company's shareholders on October 26, 2022. On October 25, 2023, the Company's shareholders approved an additional 3,450 shares to be added to the 2018 plan. The 2018 Plan shares available for issuance also include 948 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”). 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 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 3,091 available shares for future grant under the 2018 Plan at September 27, 2024.

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 financial performance goals, either on an absolute basis or relative to a peer group of companies. Payouts under performance-based restricted stock awards may also be

subject to modification based on Mercury’s total shareholder return relative to the component companies within the Spade Defense Index.

EMPLOYEE STOCK PURCHASE PLAN

The Company’s 1997 Employee Stock Purchase Plan, as amended and restated (the “1997 ESPP”) was terminated in accordance with its terms effective May 14, 2024. Under the 1997 ESPP, rights were 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 1997 ESPP permitted employees to purchase common stock through payroll deductions, which may not have exceeded 10% of an employee’s compensation as defined in the 1997 ESPP. There were no shares issued under the 1997 ESPP during the first quarter ended September 29, 2023.

The Company adopted a new employee stock purchase plan (the “2024 ESPP”) in April 2024. The Company's shareholders approved the plan at the Company’s 2024 annual meeting of shareholders, held on October 23, 2024. The number of shares authorized for issuance under the 2024 ESPP is 1,000 shares. Under the 2024 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 2024 ESPP permits employees to purchase common stock through payroll deductions, which may not exceed 10% of an employee’s compensation as defined in the 2024 ESPP. As of September 27, 2024, no shares have been issued under the 2024 ESPP.

STOCK OPTION AND AWARD ACTIVITY

On August 15, 2023, the Company announced that William L. Ballhaus was appointed as the Company’s President and Chief Executive Officer. Mr. Ballhaus received an onboarding grant of premium-priced stock options ("New Hire Option") under the 2018 Plan. The Company and Mr. Ballhaus are parties to an employment agreement, which is included in exhibit 10.1 on Form 8-K filed by the Company with the SEC on August 15, 2023.

The following table summarizes activity of the Company's stock option plans since June 28, 2024:

K.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. The Company evaluated its internal organization under FASB ASC 280, Segment Reporting (“ASC 280”) to determine whether there has been a change to its conclusion of a single operating and reportable segment. The Company concluded there has been no changes 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 SEPTEMBER 27, 2024
Net revenues to unaffiliated customers	$	192,660	$	11,771	$	—	$	—	$	204,431

The Company offers a broad family of products and processing solutions 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 processing solutions often must also meet significant size, weight and power ("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 solutions 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
	September 27, 2024		September 29, 2023
Domestic(1)	$	161,194	$	146,467
International/Foreign Military Sales(2)	43,237		34,524
Total Net Revenue	$	204,431	$	180,991

(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 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.

L.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 business. Although legal proceedings are inherently unpredictable, the Company believes that it has valid defenses with respect to those 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 December 7, 2021, counsel for National Technical Systems, Inc. (“NTS”) sent the Company an environmental demand letter pursuant to Massachusetts General Laws Chapter 21E, Section 4A, and CERCLA 42 U.S.C. Section 9601, related to a site that NTS formerly owned at 533 Main Street, Acton, Massachusetts. NTS received a Notice of Responsibility from the Massachusetts Department of Environmental Protection (“MassDEP”) alleging trichloroethene, freon and 1,4-dioxane contamination in the groundwater emanating from NTS’s former site. NTS alleges in its demand letter that the operations of a predecessor company to the Company that was acquired in the Company's acquisition of the Microsemi Carve-Out Business that once owned and operated a facility at 531 Main Street, Acton, Massachusetts contributed to the groundwater contamination. NTS is seeking payment from the Company of NTS’s costs for any required environmental remediation. In April 2022, the Company engaged in a meet and confer session with NTS pursuant to Massachusetts General Laws Chapter 21E, Section 4A to discuss the status of the environmental review performed by NTS and its licensed site professional. The Company subsequently delivered a letter to NTS outlining the deficiencies in their claim and reiterated that the Company is not obligated to tender a substantive response to their demand without first having received the responsive information requested in connection with the meet and confer session. In April 2024, counsel for NTS sent additional communications on their demand that the Company participate in their environmental monitoring and remediation planning, and in May 2024, the Company responded with a rebuttal of the allegations. The Company believes the NTS claims are without merit and intends to defend itself vigorously. In addition, in November 2021, the Company responded to a request for information from MassDEP regarding the detection of PFAS (per- and polyfluoroakyl substances) in the Acton, Massachusetts Water District’s Conant public water supply wells near the former facility at 531 Main Street, Acton, Massachusetts at a level above the standard that MassDEP published for PFAS in October 2020. The Company has not been contacted by MassDEP since the Company's response was provided in November 2021. It is too early to determine what responsibility, if any, Mercury may have for these environmental matters.

On June 19, 2023, the Board of Directors received notice of the Company’s former CEO’s resignation from the positions of President and Chief Executive Officer. The Board accepted his resignation effective June 24, 2023. In the notice, the former CEO claimed he was entitled to certain benefits, including equity vesting, severance, and other benefits, under the change in control severance agreement (the “CIC Agreement”) because the former CEO had resigned with good reason during a potential change in control period. The Company disputes these claims and maintains that the former CEO resigned without good reason. On September 19, 2023, the former CEO filed for binding arbitration under the employment rules of the American Arbitration Association (“AAA”). An arbitrator was appointed on November 29, 2023, and an arbitration trial that was initially scheduled for mid-December 2024 has been rescheduled to late March 2025. On March 25, 2024, the arbitrator denied Mr. Aslett's motion for compensation during the dispute and payment of his legal fees, preserving those matters for the arbitration trial. The Company intends to contest vigorously the claims under the CIC Agreement and believes that the Company has strong arguments that the former CEO’s claims lack merit. If the arbitrator rules in the Company’s favor, the Company may still need to pay the former CEO’s reasonable legal fees, interest, and compensation during the dispute. If instead the arbitrator rules for the former CEO, the Company could be liable for up to approximately $14,100, based on the closing price of the Company's common stock on June 26, 2023, for accelerated equity vesting, severance, and other benefits under the CIC Agreement, plus interest, legal fees and expenses and compensation during dispute, which could include Mr. Aslett's base salary and other amounts based on the compensation, benefit and insurance plans in which he participated. The Company categorically denies any wrongdoing or liability under the CIC Agreement, but the outcome of potential arbitration is inherently uncertain. Accordingly, it is reasonably possible that the Company will incur a liability in this matter, and the Company estimates the potential range of exposure from $0 to $14,100, plus costs and attorneys’ fees, interest and compensation to the former CEO during the dispute.

On December 13, 2023, a securities class action complaint was filed against the Company, Mark Aslett, and Michael Ruppert in the U.S. District Court for the District of Massachusetts. The complaint asserted Section 10(b) and 20(a) securities fraud claims on behalf of a purported class of purchasers and sellers of the Company's stock from December 7, 2020, through June 23, 2023. The complaint alleged that the Company's public disclosures in SEC filings and on earnings calls were false and/or misleading. On February 27, 2024, the Court entered an order appointing Carpenters Pension Trust Fund for Northern California as lead plaintiff. On April 18, 2024, the lead plaintiff filed an amended complaint including William Ballhaus and David Farnsworth as additional defendants and amended the class period to February 3, 2021 through February 6, 2024. The Company filed a motion to dismiss on May 24, 2024, and after the plaintiffs’ filed their opposition motion and the Company filed its reply to their opposition, a hearing on the motion was conducted by the Court on July 24, 2024. On July 24, 2024, the Court dismissed the case without prejudice and permitted the plaintiffs 30 days to file an amended complaint. The plaintiffs filed for leave to amend their complaint on August 23, 2024, Mercury filed its opposition motion on September 6th, the plaintiffs filed their response brief on September 17, 2024, and Mercury filed its reply on September 30, 2024. On October 17, 2024, Mercury received a shareholder derivative demand alleging the same claims as those covered in the federal securities class action. Subject to the terms of the Company's by-laws and applicable Massachusetts law, Mr. Aslett, the Company's former Chief Executive Officer, and Mr. Ruppert, the Company's former Chief Financial Officer, Mr. Ballhaus, the Company's current Chief Executive Officer, and Mr. Farnsworth, the Company's current Chief Financial officer, are indemnified by the

Company for this matter. The Company believes the claims in the complaints are without merit and intends to defend itself vigorously. It is too early to determine what responsibility, if any, the Company will have for this matter.

On January 31, 2024, a former employee at the Company's Torrance, California location, filed a wage and hour class action lawsuit in California state court in Los Angeles County, along with a companion Private Attorneys General Act (“PAGA”) lawsuit, to act in a representative capacity for other Mercury Mission Systems, LLC employees in California, alleging a range of violations of California wage and hour regulations. On October 1, 2024, a second former employee at our Torrance location filed a PAGA notice to act in a representative capacity on allegations of a range of violations of California wage and hour regulations. The Company believes the claims in the complaints are without merit and intends to defend itself vigorously. It is too early to determine what responsibility, if any, the Company will have for this matter.

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 September 27, 2024, 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 $120,574.

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.

M.Derivatives

The Company utilizes interest rate derivatives to mitigate interest rate exposure with respect to its financing arrangements. On September 29, 2022, the Company entered into the Swap with JP Morgan Chase Bank, N.A. ("JPMorgan") for a notional amount of $300,000 in order to fix the interest rate associated with a portion of the total $511,500 existing borrowings on the Revolver at the time of the Swap. The Swap agreement was designated and qualified for hedge accounting treatment as a cash flow hedge. The Swap was scheduled to mature on February 28, 2027, coterminous with the maturity of the Revolver. The Swap established a fixed interest rate on the first $300,000 of the Company's outstanding borrowings against the Revolver obligation at 3.79%.

On September 28, 2023, the Company terminated the Swap. At the time of termination, the fair value of the Swap was an asset of $7,403. The Company received the cash settlement of $7,403 and these proceeds are classified within Operating Activities of the Consolidated Statements of Cash Flows.

Following the termination of the Swap, the Company entered into the September 2023 Swap agreement on September 28, 2023 with JPMorgan for a notional amount of $300,000 in order to fix the interest rate associated with a portion of the total $576,500 existing borrowings on Company's Revolver at the time of the Swap at 4.66%. The September 2023 Swap agreement was designated and qualified for hedge accounting treatment as a cash flow hedge. The September 2023 Swap matures on February 28, 2027, coterminous with the maturity of the Revolver.

As of September 27, 2024, the fair value of the September 2023 Swap was a liability of $9,628 and is included within Other non-current liabilities in the Company's Consolidated Balance Sheets.

During the first quarter ended September 27, 2024, the Company amortized a total of $881 of the gain associated with the interest swaps terminated on September 29, 2022 and September 28, 2023, which is included within Other comprehensive loss.

The market risk associated with the Company’s derivative instrument is the result of interest rate movements that are expected to offset the market risk of the underlying arrangement. The counterparty to the September 2023 Swap is JPMorgan. Based on the credit ratings of the Company’s counterparty as of September 27, 2024, nonperformance is not perceived to be a material risk. Furthermore, none of the Company’s derivatives are subject to collateral or other security arrangements and none contain provisions that are dependent on the Company’s credit ratings from any credit rating agency. While the contract or notional amounts of derivative financial instruments provide one measure of the volume of these transactions, they do not represent the amount of the Company’s exposure to credit risk. The amounts potentially subject to credit risk (arising from the possible inability of the counterparty to meet the terms of their contracts) are generally limited to the amounts, if any, by which the counterparty obligations under the contracts exceed the obligations of the Company to the counterparty. As a result of the above considerations, the Company does not consider the risk of counterparty default to be significant.

N.Subsequent Events

The Company has evaluated subsequent events from the date of the Consolidated Balance Sheet through the date the consolidated financial statements were issued and noted no items requiring adjustment of the financial statements or additional disclosures.

REVENUES

Total revenues increased $23.4 million, or 13.0%, to $204.4 million during the first quarter ended September 27, 2024, as compared to $181.0 million during the first quarter ended September 29, 2023. Revenues increased year over year as we pivoted our resources in fiscal 2024 to executing on our program base, including progress toward full rate production of our common processing architecture. As a result, we are experiencing a temporary volume shift in our total revenue, including our point in time revenue and over time revenue which increased by approximately $16.0 million and $7.4 million, respectively. Over time revenue represented 55% of total revenues during the first quarter ended September 27, 2024, as compared to 58% of total revenues during the first quarter ended September 29, 2023.

Revenue increases were driven by the modules and sub-assemblies, integrated solutions, and components product groupings which increased $8.3 million, $7.8 million and $7.4 million, respectively during the first quarter ended September 27, 2024 when compared to the prior period. The increase in total revenue was primarily driven by the other, radar, other sensor and effector, and electronic warfare end applications with increases of $14.3 million, $7.0 million, $5.2 million, and $1.9 million respectively, partially offset by a decrease to C4I end applications of $5.0 million. The increase in total revenue was also driven by higher Other, Space, and Land platforms of $20.2 million, $9.3 million and $8.6 million, respectively, partially offset by decreases to Airborne and Naval platforms of $14.2 million and $0.5 million, respectively. The largest program increases were related to a strategic weapons program, a secure processing program, and MH-60R/S, partially offset by decreases in the F-35, AARGM, and CH-53K programs when compared to the prior period. There were no programs comprising 10% or more of our revenues for the first quarters ended September 27, 2024 or September 29, 2023.

GROSS MARGIN

Gross margin was 25.3% for the first quarter ended September 27, 2024, a decrease of 260 basis points from the 27.9% gross margin realized during the first quarter ended September 29, 2023. The lower gross margin was driven primarily by higher manufacturing adjustments and inventory reserves of $11.2 million, partially offset by net EAC change impact on our programs recognized over time of approximately $8.3 million recorded in the quarter, an incremental improvement of approximately $8.2 million, or 500 basis points, when compared to the prior period.

We had the following aggregate effects of favorable and unfavorable margin impacts as a result of changes in estimates across our portfolio for the period presented:


	First Quarters Ended
(in thousands)	September 27, 2024		September 29, 2023
Gross favorable	$	7,774	$	6,335
Gross unfavorable	(16,067)		(22,798)
Net impact of changes in estimates	$	(8,293)	$	(16,463)

The changes in estimates are assessed based on historical results and cumulative adjustments are recorded to recognize revenue to date based on changes in estimated margin on programs, including impact of contract amendments factored for potential risks and opportunities. We utilize the latest and best information available when revising our estimates and apply consistent judgement across the full portfolio of programs.

SELLING, GENERAL AND ADMINISTRATIVE

Selling, general and administrative expenses decreased $2.6 million, or 7.4%, to $33.2 million during the first quarter ended September 27, 2024, as compared to $35.8 million in the first quarter ended September 29, 2023. The decrease was primarily driven by the savings from reductions in force initiated in fiscal 2024, resulting in lower compensation costs including $5.0 million of salary and benefit expense as well as lower software licensing fees of $1.2 million, and lower directors fees of $0.5 million. These decreases were partially offset by higher stock-based compensation of $2.9 million.

RESEARCH AND DEVELOPMENT

Research and development expenses decreased $13.5 million, or 42.3%, to $18.4 million during the first quarter ended September 27, 2024, as compared to $31.9 million during the first quarter ended September 29, 2023. The decrease during the first quarter ended September 27, 2024 was primarily driven by the savings from reductions in force initiated in fiscal 2024, reducing headcount by approximately 130, resulting in lower expense of $10.0 million as well as decreased spend on equipment, supplies, and outside services of $3.8 million.

AMORTIZATION OF INTANGIBLE ASSETS

Amortization of intangible assets decreased $1.3 million to $11.2 million during the first quarter ended September 27, 2024, as compared to $12.5 million during the first quarter ended September 29, 2023, primarily due to various developed technology and customer relationship intangibles being fully amortized in fiscal 2024.

RESTRUCTURING AND OTHER CHARGES

We incurred $2.3 million of restructuring and other charges during the first quarter ended September 27, 2024, as compared to $9.5 million during the first quarter ended September 29, 2023. Restructuring and other charges during the first quarter ended September 27, 2024 are primarily related to severance related charges. Restructuring and other charges during the first quarter ended September 29, 2023 includes $9.5 million of severance costs related to a workforce reduction that eliminated approximately 150 positions.

ACQUISITION COSTS AND OTHER RELATED EXPENSES

There was an immaterial amount of acquisition costs and other related expenses during the first quarter ended September 27, 2024. The acquisition costs and other related expenses during the first quarter ended September 29, 2023 includes $0.3 million related to the conclusion of the Board of Directors' review of strategic alternatives, as well as $0.3 million for third-party advisory fees in connection with engagements by activist investors.

INTEREST EXPENSE

We incurred $8.9 million of interest expense during the first quarter ended September 27, 2024, as compared to $7.9 million during the first quarter ended September 29, 2023. The increase was driven by a higher interest rate and higher average outstanding borrowings during the period on our existing credit facility (the "Revolver").

OTHER EXPENSE, NET

Other expense, net was $1.3 million during the first quarter ended September 27, 2024, as compared to $1.8 million during the first quarter ended September 29, 2023. The first quarter ended September 27, 2024 includes $2.3 million of financing costs, $0.5 million of consulting costs, and $0.2 million securities class action expenses, partially offset by $1.5 million net foreign currency translation gains and $0.2 million of other income. The first quarter ended September 29, 2023 includes net foreign currency translation losses of $1.0 million, financing costs and litigation and settlement expenses of $0.5 million, partially offset by other income of $0.3 million.

INCOME TAXES

We recorded an income tax benefit of $5.6 million and $13.0 million on a loss before income taxes of $23.1 million and $49.7 million for the first quarters ended September 27, 2024 and September 29, 2023, respectively.

During the first quarters ended September 27, 2024 and September 29, 2023, we recognized a tax provision of $0.2 million and $1.2 million related to stock compensation shortfalls, respectively.

The effective tax rate for the first quarters ended September 27, 2024 differed from the federal statutory rate primarily due to federal and state research and development credits, non-deductible compensation and state taxes. The effective tax rate for the first quarter ended September 29, 2023 differed from the federal statutory rate primarily due to federal and state research and development credits and state taxes.

We continue to maintain a valuation allowance on the majority of our foreign net operating loss carryforwards and state research and developmental tax credit carryforwards. Based on forecasted taxable income and the scheduled reversal of the remaining deferred tax assets, we believe it is more likely than not that all other deferred tax assets will be recognized.

LIQUIDITY AND CAPITAL RESOURCES

Our primary sources of liquidity come from existing cash and cash generated from operations, our Revolver, our ability to raise capital under our universal shelf registration statement and our ability to factor our receivables. Our near-term fixed commitments for cash expenditures consist primarily of payments under operating leases and inventory purchase commitments. We have experienced growth in our working capital balances and, in particular, related to unbilled receivables and inventory over the last several years. As we receive follow-on production awards, we believe that both unbilled receivables and inventory is expected to convert to cash reducing our working capital balances.

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 October 4, 2023, 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 Facilities

On November 7, 2023, due to the uncertainty surrounding a government shutdown or prolonged continuing resolution and the potential impact on the second quarter and fiscal 2024 results, we proactively executed Amendment No. 5 to the Revolver, as amended to date, with a syndicate of commercial banks and Bank of America, N.A acting as the administrative agent allowing for a temporary increase in the Consolidated Total Net Leverage Ratio covenant requirement from 4.50 to 5.25 for the second quarter ended December 29, 2023. As part of Amendment No. 5, the Company agreed to a temporary reduction of Revolver capacity to $750.0 million through the earlier of May 15, 2024 or the filing of the compliance certificate for the period ended March 29, 2024.

On August 13, 2024, we executed Amendment No. 6 to the Revolver, decreasing the permanent borrowing capacity to $900.0 million, with a temporary reduction in credit availability to $750.0 million until we meet a minimum consolidated EBITDA level of $75.0 million.

During the first quarter ended September 27, 2024, we did not have any additional borrowings or repayments. As of September 27, 2024, the Company was in compliance with all covenants and conditions under the Revolver and expects to be within our covenant and conditions for the remainder of the year. The borrowing capacity as defined under the Revolver as of September 27, 2024 is approximately $750.0 million, less outstanding borrowings of $591.5 million.

Receivables Purchase Agreement

On September 27, 2022, we entered into an uncommitted receivables purchase agreement (“RPA”), pursuant to which we may offer to sell certain customer receivables, subject to the terms and conditions of the RPA. The RPA is an uncommitted arrangement such that we are not obligated to sell any receivables and the party has no obligation to purchase any receivables from us. Pursuant to the RPA, the party may purchase certain of our customer receivables at a discounted rate, subject to a limit that as of any date, the total amount of purchased receivables held by the party, less the amount of all collections received on such receivables, may not exceed $20.0 million. The RPA has an indefinite term and the agreement remains in effect until it is terminated by either party. On March 14, 2023, we amended the RPA to increase the capacity from $20.0 million to $30.6 million. On June 21, 2023, we further amended the RPA to increase the capacity from $30.6 million to $60.0 million. On August 13, 2024, we terminated the RPA in conjunction with entering into a new receivables purchase and service agreement.

On August 13, 2024, we entered into a $60.0 million committed receivables purchase and servicing agreement (“RPSA”) with a new party. The RPSA has an initial term of two years. Pursuant to the RPSA, the new party has committed to purchase receivables from a certain number of agreed upon customers, maintaining a balance of purchased receivables at or below $60.0 million. We factored accounts receivable and incurred factoring fees of approximately $43.7 million and $0.4 million, respectively, for the first quarter ended September 27, 2024. We received $18.8 million of factoring proceeds on the first business day of the second quarter that were outstanding as of September 27, 2024. The $18.8 million was included in Accounts receivable, net of allowance for credit losses on the Consolidated Balance Sheet as of September 27, 2024. We factored accounts receivable and incurred factoring fees of approximately $28.8 million and $0.3 million respectively, for the first quarter ended September 29, 2023.

CASH FLOWS


	As of and For the First Quarters Ended,
(In thousands)	September 27, 2024		September 29, 2023
Net cash used in operating activities	$	(14,660)	$	(39,068)
Net cash used in investing activities	$	(6,236)	$	(8,015)
Net cash (used in) provided by financing activities	$	(2,249)	$	65,000
Net (decrease) increase in cash and cash equivalents	$	(22,398)	$	17,806
Cash and cash equivalents at end of period	$	158,123	$	89,369

Our cash and cash equivalents decreased by $22.4 million from June 28, 2024 to September 27, 2024, as the result of $14.7 million of cash used in operating activities, $6.2 million invested in purchases of property and equipment, and $2.2 million of cash paid in deferred financing and offering costs.

Operating Activities

During the first quarter ended September 27, 2024, we had an outflow of $14.7 million in cash from operating activities compared to a $39.1 million outflow during the first quarter ended September 29, 2023. The lower outflow during the first quarter ended September 27, 2024 was primarily due to a higher inflow from deferred revenues and customer advances of $19.5 million, a lower net loss of $19.2 million, an income tax refund received of $1.0 million as compared to income tax payments of $13.9 million during the first quarter ended September 29, 2023, and a $13.7 million reduced outflow of inventory. This activity was partially offset by a $6.1 million outflow from accounts receivable, unbilled receivables and costs in excess of billings as compared to a $27.0 million inflow during the first quarter ended September 29, 2023 and a $14.0 million higher outflow from accounts payable, accrued expenses, and accrued compensation. The first quarter ended September 29, 2023 also included a $7.4 million inflow from the cash settlement for the termination of the interest rate swap.

Investing Activities

During the first quarter ended September 27, 2024, we invested $6.2 million, a decrease of $1.8 million, as compared to $8.0 million during the first quarter ended September 29, 2023 due to lower purchases of property and equipment.

Financing Activities

During the first quarter ended September 27, 2024, we had no additional borrowings on our Revolver as compared to $65.0 million of borrowings during the first quarter ended September 29, 2023. The first quarter ended September 27, 2024, included $2.2 million of cash paid in deferred financing in conjunction with the amendment to our Revolver during the first quarter of fiscal 2025.

COMMITMENTS, CONTRACTUAL OBLIGATIONS AND CONTINGENCIES

The following is a schedule of our commitments and contractual obligations outstanding at September 27, 2024:


(In thousands)	Total		Less Than 1 Year		1-3 Years		3-5 Years		More Than 5 Years
Purchase obligations	$	120,574	$	120,574	$	—	$	—	$	—
Operating leases	85,590		15,455		27,035		22,762		20,338


	$	206,164	$	136,029	$	27,035	$	22,762	$	20,338

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 $120.6 million at September 27, 2024.

We have a liability at September 27, 2024 of $7.7 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.

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 would be 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, and free cash flow.

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, financing and other third party 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.

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


	First Quarters Ended
(In thousands)	September 27, 2024		September 29, 2023
Net loss	$	(17,525)	$	(36,708)
Other non-operating adjustments, net	(1,735)		731
Interest expense, net	8,362		7,760
Income tax benefit	(5,594)		(13,027)
Depreciation	9,985		10,145
Amortization of intangible assets	11,235		12,547
Restructuring and other charges	2,260		9,546
Impairment of long-lived assets	—		—
Acquisition, financing and other third party costs	2,331		1,332
Fair value adjustments from purchase accounting	177		177
Litigation and settlement expense, net	1,394		503

Stock-based and other non-cash compensation expense	10,560		8,951
Adjusted EBITDA	$	21,450	$	1,957

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, financing and other third party costs, fair value adjustments from purchase accounting, litigation and settlement income and expense, 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.

The following table reconciles net loss and diluted loss per share, the most directly comparable GAAP measures, to adjusted (loss) income and adjusted EPS:


	First Quarters Ended
(In thousands, except per share data)	September 27, 2024				September 29, 2023
Net loss and loss per share	$	(17,525)	$	(0.30)	$	(36,708)	$	(0.64)
Other non-operating adjustments, net	(1,735)				731
Amortization of intangible assets	11,235				12,547
Restructuring and other charges	2,260				9,546
Impairment of long-lived assets	—				—
Acquisition, financing and other third party costs	2,331				1,332
Fair value adjustments from purchase accounting	177				177
Litigation and settlement expense, net	1,394				503

Stock-based and other non-cash compensation expense	10,560				8,951
Impact to income taxes(1)	(6,253)				(10,758)
Adjusted income (loss) and adjusted earnings (loss) per share(2)	$	2,444	$	0.04	$	(13,679)	$	(0.24)

Diluted weighted-average shares outstanding			58,585				57,105

(1) Impact to income taxes is calculated by recasting income before income taxes to include the items involved in determining adjusted income and recalculating the income tax provision using this adjusted income from operations before income taxes. The recalculation also adjusts for any discrete tax expense or benefit related to the items.

(2) Adjusted earnings per share is calculated using diluted shares whereas Net loss per share or Adjusted loss per share is calculated using basic shares. There was no impact to the calculation of adjusted earnings per share as a result of this for the first quarters ended September 27, 2024 and September 29, 2023.

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.

The following table reconciles cash used in operating activities, the most directly comparable GAAP financial measure, to free cash flow:


	First Quarters Ended
(In thousands)	September 27, 2024		September 29, 2023
Net cash used in operating activities	$	(14,660)	$	(39,068)
Purchase of property and equipment	(6,236)		(8,015)
Free cash flow	$	(20,896)	$	(47,083)

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

There were no material changes in our exposure to market risk from June 28, 2024 to September 27, 2024.

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 September 27, 2024. 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 September 27, 2024 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

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 ourself 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 December 7, 2021, counsel for National Technical Systems, Inc. (“NTS”) sent us an environmental demand letter pursuant to Massachusetts General Laws Chapter 21E, Section 4A, and CERCLA 42 U.S.C. Section 9601, related to a site that NTS formerly owned at 533 Main Street, Acton, Massachusetts. NTS received a Notice of Responsibility from the Massachusetts Department of Environmental Protection (“MassDEP”) alleging trichloroethene, freon and 1,4-dioxane contamination in the groundwater emanating from NTS’s former site. NTS alleges in its demand letter that the operations of a predecessor company to Mercury that was acquired in our acquisition of the Microsemi Carve-Out Business that once owned and operated a facility at 531 Main Street, Acton, Massachusetts contributed to the groundwater contamination. NTS is seeking payment from us of NTS’s costs for any required environmental remediation. In April 2022, we engaged in a meet and confer session with NTS pursuant to Massachusetts General Laws Chapter 21E, Section 4A to discuss the status of the environmental review performed by NTS and its licensed site professional. We subsequently delivered a letter to NTS outlining the deficiencies in their claim and reiterated that we are not obligated to tender a substantive response to their demand without first having received the responsive information requested in connection with the meet and confer session. In April 2024, counsel for NTS sent additional communications on their demand that we participate in their environmental monitoring and remediation planning, and in May 2024, we responded with a rebuttal of the allegations. We believe the NTS claims are without merit and intend to defend our self vigorously. In addition, in November 2021, we responded to a request for information from MassDEP regarding the detection of PFAS (per- and polyfluoroakyl substances) in the Acton, Massachusetts Water District’s Conant public water supply wells near the former facility at 531 Main Street, Acton, Massachusetts at a level above the standard that MassDEP published for PFAS in October 2020. We have not been contacted by MassDEP since our response was provided in November 2021. It is too early to determine what responsibility, if any, we may have for these environmental matters.

On June 19, 2023, our Board of Directors received notice of our former CEO’s resignation from his positions of President and Chief Executive Officer. The Board accepted his resignation effective June 24, 2023. In his notice, the former CEO claimed he was entitled to certain benefits, including equity vesting, severance, and other benefits, under his change in control severance agreement (the “CIC Agreement”) because he had resigned with good reason during a potential change in control period. We dispute these claims and maintain that he resigned without good reason. On September 19, 2023, our former CEO filed for binding arbitration under the employment rules of the American Arbitration Association (“AAA”). An arbitrator was appointed on November 29, 2023, and an arbitration trial that was initially scheduled for mid-December 2024 has been rescheduled to late March 2025. On March 25, 2024, the arbitrator denied Mr. Aslett’s motion for compensation during the dispute and payment of his legal fees, preserving those matters for the arbitration trial. We intend to contest vigorously the claims under the CIC Agreement and believe that we have strong arguments that our former CEO’s claims lack merit. If the arbitrator rules in our favor, we may still need to pay the former CEO’s reasonable legal fees, interest, and compensation during the dispute. If instead the arbitrator rules for the former CEO, we could be liable for up to approximately $14.1 million, based on the closing price of our common stock on June 26, 2023, for accelerated equity vesting, severance and other benefits under the CIC Agreement, plus interest, legal fees and expenses and compensation during dispute, which could include Mr. Aslett's base salary and other amounts based on the compensation, benefit and insurance plans in which he participated. We categorically deny any wrongdoing or liability under the CIC Agreement, but the outcome of potential arbitration is inherently uncertain. Accordingly, it is reasonably possible that we will incur a liability in this matter, and we estimate the potential range of exposure from $0 to $14.1 million, plus costs and attorneys’ fees, interest, and compensation to our former CEO during the dispute.

On December 13, 2023, a securities class action complaint was filed against us, Mark Aslett, and Michael Ruppert in the U.S. District Court for the District of Massachusetts. The complaint asserted Section 10(b) and 20(a) securities fraud claims on behalf of a purported class of purchasers and sellers of our stock from December 7, 2020, through June 23, 2023. The complaint alleged that our public disclosures in SEC filings and on earnings calls were false and/or misleading. On February 27, 2024, the Court entered an order appointing Carpenters Pension Trust Fund for Northern California as lead plaintiff. On April 18, 2024, the lead plaintiff filed an amended complaint including William Ballhaus and David Farnsworth as additional defendants and amended the class period to February 3, 2021 through February 6, 2024. We filed a motion to dismiss on May 24, 2024, and after the plaintiffs’ filed their opposition motion and we filed our reply to their opposition, a hearing on the motion was conducted by the Court on July 24, 2024. On July 24, 2024, the Court dismissed the case without prejudice and permitted the plaintiffs 30 days to file an amended complaint. The plaintiffs filed for leave to amend their complaint on August 23, 2024, Mercury filed its opposition motion on September 6th, the plaintiffs filed their response brief on September 17th, and Mercury filed our reply on September 30th. On October 17, 2024, Mercury received a shareholder derivative demand alleging the same

claims as those covered in the federal securities class action. Subject to the terms of our by-laws and applicable Massachusetts law, Mr. Aslett, our former Chief Executive Officer, Mr. Ruppert, our former Chief Financial Officer, Mr. Ballhaus, our current Chief Executive Officer, and Mr. Farnsworth, our current Chief Financial officer, are indemnified by us for this matter. We believe the claims in the complaints are without merit and intend to defend our self vigorously. It is too early to determine what responsibility, if any, we will have for this matter.

On January 31, 2024, a former employee at our Torrance, California location, filed a wage and hour class action lawsuit in California state court in Los Angeles County, along with a companion Private Attorneys General Act (“PAGA”) lawsuit, to act in a representative capacity for other Mercury Mission Systems, LLC employees in California, alleging a range of violations of California wage and hour regulations. On October 1, 2024, a second former employee at our Torrance location filed a PAGA notice to act in a representative capacity on allegations of a range of violations of California wage and hour regulations. We believe the claims in the complaints are without merit and intend to defend our self vigorously. It is too early to determine what responsibility, if any, Mercury will have for this matter.

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 June 28, 2024. There has been no changes from the factors disclosed in our 2024 Annual Report on Form 10-K filed on August 13, 2024, although we may disclose additional changes to such factors from time to time in our future filings with the Securities and Exchange Commission.

ITEM 5. OTHER INFORMATION

The table below has defined terms that are used throughout this Agreement: Defined Term Meaning “You” or “Employee” Allen Couture Employee ID #: 16672 “Separation Date” February 16, 2024 “Human Resources Business Partner” Steve Ratner “Number of Weeks of Salary Continuation after Termination of Employment” 52 weeks “Due Date for Signed Agreement” February 26, 2024 You must take the following actions to obtain the Special Severance Package: 1. You must sign this Agreement and then email that signed Agreement to Steve Ratner by the later of (a) the Due Date for Signed Agreement listed above, and (b) the end of the forty-five (45) calendar day period after your receipt of this Agreement. If you cannot email the signed Agreement, please contact your Human Resources Business Partner for mailing instructions or other delivery options. 2. After the Separation Date, you must sign and deliver the Affirmation of Separation Agreement and General Release that is attached to this Agreement as Exhibit A (the “Affirmation”) to the Company by email to Steve Ratner before the end of the forty-five (45) calendar day period after the Separation Date. If you cannot email the Agreement, please contact your Human Resources Business Partner for mailing instructions or other delivery options. 3. You must not revoke this Agreement during the revocation period specified in the “Consideration/Revocation” section of this Agreement. Special Severance Package The Company will provide you with the Special Severance Package described below in consideration of your acceptance of all of the terms and conditions of this Agreement and subject to your compliance with the terms and conditions hereunder. 1. Continued Employment. The Company will continue your employment through the Separation Date.

Page 2 50 Minuteman Road • Andover, MA 01810 • 866.627.6951 • mrcy.com Does not contain Technical Data. //Private and Restricted/No Tech Data// 2. Salary Continuation. The Company will pay your regular salary to you for a period of week(s) equal to the Number of Weeks of Salary Continuation after Termination of Employment listed in the table on page 1 of this Agreement (the “Salary Continuation Period”), less legally-required and voluntarily-authorized deductions (such payments, the “Salary Continuation”). The Company will make the Salary Continuation payments to you beginning with the first payroll cycle after the Effective Date of the Affirmation. The Salary Continuation will be paid in equal installments on the Company’s regularly scheduled paydays. 3. Bonus. You will receive a lump sum payment of your target annual bonus (excluding any potential over- achievement bonus) for Fiscal Year 2024. Any amount payable to you under this section will be paid to you in the ordinary course of the Company’s business. 4. Amendment to FY23 Outstanding Equity Awards. Your outstanding fiscal 2023 equity awards shall be amended to provide the same severance-based vesting as was included in your fiscal 2024 equity awards, such that in the event of a qualifying termination for non-change in control severance, that the vesting of the time-based awards shall accelerate at the Separation Date for equity awards that would vest in the Salary Continuation Period, and the vesting of the performance awards shall be prorated at the Separation Date with the actual payout dependent on the Company’s performance for the entire performance period. 5. Benefits. If you currently participate in medical, vision and/or dental coverage under the Company’s group health plan, and you properly and timely elect to continue such coverage in accordance with the continuation requirements of COBRA, then the Company shall pay the same portion of your premium as it pays with respect to active employees (at the same level of coverage for you and your covered dependents in effect immediately prior to the Separation Date) for a period of time equal to the Salary Continuation Period (unless your COBRA coverage period ends earlier) (the “COBRA Payment Period”). Following the COBRA Payment Period, and provided that the COBRA coverage period has not expired, you shall be entitled to continue your elected COBRA coverage for the remainder of the COBRA coverage period at your own and sole expense. Company payments of your COBRA premiums are subject to all the terms and conditions set forth in the Company’s group health plan and are intended to avoid any excise tax under Section 4980D of the Internal Revenue Code of 1986, as amended (the “Code”). If the Company, in its sole discretion, determines that the payments of any COBRA premiums would violate the nondiscrimination rules or cause the reimbursement of claims to be taxable under the Patient Protection and Affordable Care Act of 2010, together with the Health Care and Education Reconciliation Act of 2010 (collectively, the “Act”) or Section 105(h) of the Code, the premium payments may be imputed as income and treated as taxable to you to the extent necessary to eliminate any discriminatory treatment or taxation under the Act or Section 105(h) of the Code. If you become employed by another employer and are eligible for coverage under the group benefits plan of the new employer, then the Company will no longer pay premiums for COBRA continuation as of the date of eligibility. You agree to immediately notify the Company in writing of such new employment so that the Company receives such notification prior to the commencement of such new employment. You shall deliver such notice to Mercury Systems, Inc., Attention: Total Rewards, 50 Minuteman Road, Andover, MA 01810.

The Company pay you $30,000, less legally-required and voluntarily-authorized deductions, in lieu of providing you up for such dollar amount of executive outplacement services through a provider designated by the Company. The Company will make this payment to you with the first payroll cycle after the Effective Date of the Affirmation. 7. Waiver of Reimbursement Obligations. The Company will waive any obligation that you reimburse the Company for tuition payments previously reimbursed to you, any signing bonus, or any relocation or immigration assistance paid or provided to you by the Company that would otherwise be required to be repaid to the Company in connection with the termination of your employment. You understand and agree that you would not receive the monies and/or benefits specified above, except for your timely signing and non-revocation of this Agreement and the fulfillment of the promises contained herein. If you breach any provision of this Agreement, then you shall not be entitled to any additional monies and/or benefits specified above; however, your release of claims shall remain in effect. Performance of Job Duties You must continue to satisfactorily perform your job duties through the Separation Date. Those actions include, but are not limited to, continuing to work your regularly scheduled hours, organizing your electronic and hard copy files for transition to appropriate persons designated by the Company, your professional and good faith participation in any meetings with appropriate Company employees regarding your responsibilities and past and current projects, maintaining a professional, discreet, and collaborative demeanor during any interactions with Company employees, customers, suppliers, and/or consultants, and your performance of any other duties or projects that may be directed by the Company to assist with the transition of your duties. Acknowledgements and Affirmations You affirm that you have not filed, caused to be filed, or presently are a party to any claim against the Company. Nothing in this Agreement or these affirmations is intended to impair your rights under whistleblower laws or cause you to disclose your participation in any governmental whistleblower program or any whistleblowing statute(s) or regulation(s) allowing for anonymity. You also affirm that you have reported all hours worked as of the date you sign this Agreement and have been paid and/or has received all compensation, wages, bonuses, commissions, paid sick leave, predictability pay, and/or benefits which are due and payable as of the date you sign this Agreement, except for any payments due under the Special Severance Package. You also affirm you have been reimbursed for all necessary expenses or losses in following the Company’s directions or incurred by you within the scope of your employment as of the date you sign this Agreement. You affirm that you have no known workplace injuries or occupational diseases. You further affirm that you have been granted any leave to which you were entitled under the Family and Medical Leave Act and state and local leave and disability accommodation laws. You also affirm that you have not reported internally to the Company any allegations of wrongdoing by the Company or its officers, including any allegations of corporate fraud, and you have not been retaliated against for reporting any such allegations internally to the Company.

Collective/Class Action Waiver. If any claim is not subject to release, to the extent permitted by law, you waive any right or ability to be a class or collective action representative or to otherwise participate in any putative or certified class, collective or multi-party action or proceeding based on such a claim in which the Company or any other Releasee identified in this Agreement is a party. Waiver of Civil Code Section 1542 The following provision is applicable to you only if you have worked for the Company in California. To effect a full and complete general release as described above, you expressly waive and relinquish all rights and benefits of section 1542 of the Civil Code of the State of California, and do so understanding and acknowledging the significance and consequence of specifically waiving section 1542. Section 1542 of the Civil Code of the State of California states as follows: A general release does not extend to claims that the creditor or releasing party does not know or suspect to exist in his or her favor at the time of executing the release and that, if known by him or her, would have materially affected his or her settlement with the debtor or released party. Thus, notwithstanding the provisions of section 1542, and to implement a full and complete release and discharge of the Releasees, you expressly acknowledge this Agreement is intended to include in its effect, without limitation, all claims you do not know or suspect to exist in your favor at the time of signing this Agreement, and that this Agreement contemplates the extinguishment of any such claims. You warrant you have read this Agreement, including this waiver of California Civil Code section 1542, and that you have consulted with or had the opportunity to consult with counsel of your choosing about this Agreement and specifically about the waiver of section 1542, and that you understand this Agreement and the section 1542 waiver, and so you freely and knowingly enters into this Agreement. You further acknowledge that you later may discover facts different from or in addition to those you now know or believe to be true regarding the matters released or described in this Agreement, and even so you agree that the releases and agreements contained in this Agreement shall remain effective in all respects notwithstanding any later discovery of any different or additional facts. You expressly assume any and all risk of any mistake in connection with the true facts involved in the matters, disputes, or controversies released or described in this Agreement or with regard to any facts now unknown to you relating thereto. Non-Disclosure You agree that you will not disclose, directly or indirectly, the existence of this Agreement or any terms or provisions of this Agreement, except: (a) to members of your immediate family, on the condition that they be

Page 6 50 Minuteman Road • Andover, MA 01810 • 866.627.6951 • mrcy.com Does not contain Technical Data. //Private and Restricted/No Tech Data// advised that they cannot further disclose the same to others; (b) as may be necessary to obtain professional legal and/or tax advice; (c) as required by applicable law; and/or (d) to any federal, state or local government agency. For purposes of this paragraph, “immediate family” includes spouse, parents and children. By signing this Agreement, your signature affirms that you have not previously breached this paragraph. You acknowledge this provision constitutes a material inducement to the Company to enter into this Agreement. Nothing in this Agreement has the purpose or effect of preventing you from making truthful disclosures about alleged unlawful conduct. Additionally, this provision shall not be construed to limit your rights under the National Labor Relations Act including, but not limited to, the right to engage in protected concerted activity, including discussing terms and conditions of employment with coworkers, and attempting to improve terms and conditions of employment through channels outside the immediate employee-employer relationship, such as through the National Labor Relations Board. Non-Disparagement You agree that you will refrain from making false statements that are maliciously disparaging or defamatory about Releasees, or Releasees’ customers, suppliers, or vendors, including but not limited to communications on social media websites such as Facebook, Twitter, LinkedIn, or Glassdoor, on blogs, by text or email or other electronic means. This provision does not prohibit you from making truthful statements about the terms or conditions of your employment, or from exercising your rights under the National Labor Relations Act, government whistleblower programs, or whistleblowing statutes or regulations. Protection of Confidential Information You further agree that you have not and will never, directly or indirectly, use or disclose any Confidential Information of Releasees. For purposes of this Agreement, “Confidential Information” is defined as any and all information not generally known to others with whom Releasees do business, or plan to compete or do business (including, without limitation, information related to Releasees’ services, customers, customer lists, markets, developments, inventions, processes, formulas, technology, marketing, finances and all other business information), and also includes comparable information that Releasees receive or have received belonging to others who do business with Releasees. This obligation specifically includes, but is not limited to, information protected from disclosure by the Health Insurance Portability and Accountability Act, the Americans with Disabilities Act and all other federal and state laws governing the confidentiality of employee information. Confidential Information includes all information that Releasees receive or have received from others with any understanding, express or implied, that it will not be disclosed. Confidential information does not include information regarding wages or other terms and conditions of employment. Under the federal Defend Trade Secrets Act of 2016, you shall not be held criminally or civilly liable under any federal or state trade secret law for the disclosure of a trade secret that: (a) is made (i) in confidence to a federal, state, or local government official, either directly or indirectly, or to an attorney; and (ii) solely for the purpose of reporting or investigating a suspected violation of law; or (b) is made to your attorney in relation to a lawsuit against the Company for retaliation against you for reporting a suspected violation of law; or (c) is made in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal. You acknowledge and recognize that any disclosure of Confidential Information by you may give rise to irreparable injury to Releasees, which may not be adequately compensated by monetary damages, and that Releasees shall be entitled, in addition to any other damages, to obtain without posting a bond, an injunction restraining you from disclosing, in whole or in part, the Confidential Information (or from rendering services to any person or entity to whom such Confidential Information, in whole or in part, may be or has been disclosed). Return of Property

Assignment of Intellectual Property You hereby assign to the Company any right, title and interest to all Intellectual Property, to the maximum extent permitted by applicable law. You agree to sign any and all applications for domestic or foreign patents, copyrights, and other proprietary rights and to do such other acts (including, among others, the signing and delivery of instruments of further assurance or confirmation) requested by the Company to assign the Intellectual Property to the Company and to permit the Company to enforce any patents, copyrights and other proprietary rights in the Intellectual Property, to the maximum extent permitted by applicable law. You will not charge the Company for time spent in complying with these obligations. For purposes of this Agreement, “Intellectual Property” means inventions, copyrightable works, discoveries, developments, clinical and other research materials, methods, processes, compositions, works, concepts and ideas (whether or not patentable or copyrightable or constituting trade secrets) conceived, made, created, developed or reduced to practice by you (whether alone or with others) during your employment that relate in any way to the business, products or services of the Company or to any prospective activity of the Company, or which were assisted in any way by Company resources or facilities. Intellectual Property includes, without limitation, all Confidential Information. Furthermore, you acknowledge and agree that, without obtaining prior written authorization from the Company’s General Counsel, you are prohibited from (a) publishing any information or materials related to or arising out of your employment at the Company, and (b) mentioning the Company in any published work. Enforcement of Covenants You agree that if you violate any of the foregoing covenants, then in addition to all other remedies that may be available and damages that may be awarded to the Company, you shall continue to be bound by the restrictions set forth in such covenant until a period of twelve (12) months has expired without any violation of such provision, to the maximum extent permitted by applicable law. You further acknowledge that the scope of prohibited activities and time duration of these restrictions are reasonable in nature and are no broader than are necessary to maintain the goodwill of the Company and the confidentiality of its Confidential Information and to protect the other legitimate business interests of the Company. You further acknowledge that assertion of a breach of this Agreement by the Company shall not serve as a defense to claims arising from the Company’s enforcement of this Agreement.
