MERCURY SYSTEMS, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Amounts in thousands except per share data)
(Unaudited)
A.Description of Business
Mercury Systems, Inc. is a technology company that delivers processing power for the most demanding aerospace and defense missions. Headquartered in Andover, Massachusetts, the Company's end-to-end processing platform enables a broad range of aerospace and defense programs, optimized for mission success in some of the most challenging and demanding environments. Processing technologies that comprise the Company's platform include signal solutions, display, software applications, networking, storage and secure processing. The Company's innovative solutions are mission-ready, trusted and secure, software-defined and open and modular (the Company's differentiators), to meet customers’ most-pressing high-tech needs, including those specific to the defense community.
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 30, 2023 which are contained in the Company’s Annual Report on Form 10-K filed with the SEC on August 15, 2023. The results for the second quarter and six months ended December 29, 2023 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 second quarter of fiscal 2024 are to the quarter ended December 29, 2023. There were 13-weeks during the second quarters ended December 29, 2023 and December 30, 2022, respectively. There were 26 weeks during the six months ended December 29, 2023 and December 30, 2022, 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.
7


ACCOUNTS RECEIVABLES FACTORING
On September 27, 2022, the Company executed an uncommitted receivables purchase agreement (“RPA”) with Bank of the West, as purchaser, 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 Bank of the West has no obligation to purchase any receivables from the Company. Pursuant to the RPA, Bank of the West 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 Bank of the West, 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 with BMO Harris Bank (as successor in interest to Bank of the West) to increase the capacity from $30,600 to $60,000.
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 factoring 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 $48,205 factored accounts receivables as of December 29, 2023 and incurred factoring fees of approximately $953 and $1,261 for the second quarter and six months ended December 29, 2023. The Company had $20,000 factored in accounts receivables as of December 30, 2022 and incurred factoring fees of approximately $138 for the second quarter and six months ended December 30, 2022.
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 December 29, 2023.
REVENUE RECOGNITION
The Company recognizes revenue in accordance with ASC 606, Revenue from Contracts with Customers, (“ASC 606”). Revenues are derived from the sales of products that are grouped into one of the following three categories: (i) components; (ii) modules and sub-assemblies; and (iii) integrated subsystems. The Company also generates revenues from the performance of services, including systems engineering support, consulting, maintenance and other support, testing and installation. Each promised good or service within a contract is accounted for separately under the guidance of ASC 606 if they are distinct. Promised goods or services not meeting the criteria for being a distinct performance obligation are bundled into a single performance obligation with other goods or services that together meet the criteria for being distinct. The appropriate allocation of the transaction price and recognition of revenue is then determined for the bundled performance obligation.
Revenue recognized at a point in time generally relates to contracts that include a combination of components, modules and sub-assemblies, integrated subsystems and related system integration or other services. Contracts with distinct performance obligations recognized at a point in time, with or without an allocation of the transaction price, totaled 47% and 45% of revenues for the second quarter and six months ended December 29, 2023, respectively. Contracts with distinct performance obligations recognized at a point in time, with or without an allocation of the transaction price, totaled 44% and 40% of revenues for the second quarter and six months ended and December 30, 2022, 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 subsystems 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.
8


Total revenue recognized over time was 53% and 55% of total revenues for the second quarters and six months ended December 29, 2023, respectively. Total revenue recognized over time was 56% and 60% of total revenues for the second quarters and six months ended December 30, 2022, 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 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 $351,003 and $382,558 as of December 29, 2023 and June 30, 2023, respectively. The contract asset balance decreased due to the successful execution and billings across multiple programs, as well as, cumulative adjustments from the cost growth impact and contract settlements during the six months ended December 29, 2023. The contract liability balances were $81,596 and $57,142 as of December 29, 2023 and June 30, 2023, respectively. The contract liability increased due to a higher volume of advanced milestone billing events as well as timing of revenue conversion across multiple programs.
Revenue recognized for the second quarter and six months ended December 29, 2023 that was included in the contract liability balance at June 30, 2023 was $10,228 and $31,243, respectively. Revenue recognized for the second quarter and six months ended December 30, 2022 that was included in the contract liability balance at July 1, 2022 was $3,068 and $7,737, respectively.
REMAINING PERFORMANCE OBLIGATIONS
The Company includes in its computation of remaining performance obligations customer orders for which it has accepted signed sales orders. The definition of remaining performance obligations excludes contracts with original expected durations of less than one year, as well as those contracts that provide the customer with the right to cancel or terminate the order with no substantial penalty, even if the Company’s historical experience indicates the likelihood of cancellation or termination is remote. As of December 29, 2023, the aggregate amount of the transaction price allocated to remaining performance obligations was $657,598. The Company expects to recognize approximately 58% of its remaining performance obligations as revenue in the next 12 months and the balance thereafter.
9


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.
WEIGHTED-AVERAGE SHARES
Weighted-average shares were calculated as follows:
Second Quarters EndedSix Months Ended

Diluted weighted-average shares outstanding57,424 56,252 57,314 56,126 
Equity instruments to purchase 2,865 and 2,460 shares of common stock were not included in the calculation of diluted net loss per share for the second quarters and six months ended December 29, 2023, respectively, because the equity instruments were anti-dilutive. Equity instruments to purchase 511 and 300 shares of common stock were not included in the calculation of diluted net earnings per share for the second quarter and six months ended December 30, 2022, respectively, because the equity instruments were anti-dilutive.
RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS
In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (ASC 280): Improvements to Reportable Segment Disclosures, an amendment of the FASB Accounting Standards Codification. The amendments in this ASU address improvements to reportable segment disclosure requirements, specifically requiring disclosure of significant segment expenses. The amendment also extends certain annual disclosures to interim periods, and clarifies that single reportable segment entities must apply ASC 280 in its entirety, inclusive of this update. This ASU is effective for fiscal years beginning after December 15, 2023, as well as all interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted, including adoption in an interim period. The Company is currently evaluating the effect that this standard will have on its consolidated financial statements and related disclosures.
In December 2023, the FASB issued ASU No. 2023-09, Improvement to Income Tax Disclosures, an amendment of the FASB Accounting Standards Codification.

C.Fair Value of Financial Instruments
The following table summarizes the Companies' financial instruments measured at fair value on a recurring basis as of December 29, 2023:
 Fair Value Measurements
 December 29, 2023Level 1Level 2Level 3
Liabilities:
Interest rate swap$8,710 $ $8,710 $ 
Total$8,710 $ $8,710 $ 
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 December 29, 2023, the fair value of the September 2023 Swap was a liability of $8,710 and is 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 30, 2023:

The fair value of interest rate hedging agreement entered on September 29, 2022 ("the 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 June 30, 2023, the fair value of the Swap was an asset of $3,523 and was included within Other non-current assets in the Company's Consolidated Balance Sheets. The Company terminated the Swap during the first quarter ended September 29, 2023.
Refer to Note M for further information regarding the September 2023 Swap and the termination of the 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:

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, and also assesses potential triggering events during interim reporting periods. During the second quarter ended December 29, 2023, 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 was no triggering event during the second quarter ended December 29, 2023 that would require an interim impairment test. The Company will continue to monitor these events and circumstances in future periods and adverse changes to these events and circumstances could require the Company to perform an interim impairment test.
There has been no change to the carrying amount of goodwill during the six months ended December 29, 2023.

F.Restructuring
For the six months ended December 29, 2023, the Company initiated several immediate cost savings measures that simplify the Company’s organizational structure, facilitate clearer accountability, and align to the Company’s priorities, including: (i) embedding the 1MPACT value creation initiatives and execution into the Company’s operations; (ii) streamlining organizational structure and removing areas of redundancy between corporate and divisional organizations; and (iii) reducing selling, general, and administrative headcount and rebalancing discretionary and third party spending to better align with the Company’s priority areas. On July 20, 2023, the Company executed the plan to embed the 1MPACT value creation initiatives into operations, and on August 9, 2023, the Company approved and initiated a workforce reduction that, together with the 1MPACT related action, eliminated approximately 150 positions resulting in $9,548 of severance costs for the six months ended December 29, 2023.
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. The Company's adjustments reflected in restructuring and other charges are typically related to acquisitions and organizational redesign programs initiated as part of discrete post acquisition integration activities.
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. Refer to Note N for further information regarding the workforce reduction announced during the third quarter of fiscal 2024.
The following table presents the detail of charges included in the Company’s liability for restructuring and other charges:

G.Income Taxes
The Company recorded an income tax benefit of $18,141 and $2,151 on a loss before income taxes of $63,722 and $13,071 for the second quarters ended December 29, 2023 and December 30, 2022, respectively. The Company recorded an income tax benefit of $31,168 and $3,173 on a loss before income taxes of $113,457 and $28,428 for the six months ended December 29, 2023 and December 30, 2022, respectively.
During the second quarter and six months ended December 29, 2023, the Company recognized a tax provision of $431 and $1,646 related to stock compensation shortfalls, respectively, and during the second quarter and six months ended December 30, 2022 the Company recognized a tax provision of $134 and $1,745 related to stock compensation shortfalls, respectively. During the second quarter ended December 30, 2022, the Company recognized a tax benefit of $2,348 related to a release of income tax reserves for unrecognized income tax benefits due to the expiration of the statute of limitations.
The effective tax rate for the second quarters and six months ended December 29, 2023 and December 30, 2022 differed from the federal statutory rate primarily due to federal and state research and development credits, non-deductible compensation, stock compensation shortfalls and state taxes. The effective tax rate for the second quarter and six months ended December 30, 2022 also differed from the federal statutory rate due to the release of income tax reserves for previously unrecognized income tax benefits.
The Tax Cuts and Jobs Act of 2017 requires companies to capitalize and amortize domestic research and development expenditures over five years for tax purposes, and foreign research and development expenditures over fifteen years for tax purposes, effective for the Company beginning in the fiscal year ended June 30, 2023. As a result, the Company has recorded a deferred tax asset through the second quarter ended December 29, 2023 of $88,949. During the six months ended December 29, 2023, the Company has made $15,314 of tax payments related to this requirement. The Company will continue to monitor guidance and any proposed regulations and adjust the estimates as necessary.
H.Debt
REVOLVING CREDIT FACILITY
On February 28, 2022, the Company amended the revolving credit facility (the "Revolver") to increase and extend the borrowing capacity to a $1,100,000, 5-year revolving credit line, with the maturity extended to February 28, 2027. As of December 29, 2023, the Company's outstanding balance of unamortized deferred financing costs was $4,811, 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 November 2023 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 unamortized 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.
During the second quarter and six months ended December 29, 2023, the Company borrowed $40,000 and $105,000, respectively. As of December 29, 2023, the Company was in compliance with all covenants and conditions under the Revolver and there were outstanding borrowings of $616,500 against the Revolver, resulting in interest expense of $8,674 and $16,537 for the second quarter and six months ended December 29, 2023. The borrowing capacity as defined under the Revolver as of December 29, 2023 is approximately $750,000, less outstanding borrowings of $616,500. There were outstanding letters of credit of $963 as of December 29, 2023.
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.
13


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 December 29, 2023 was a net liability of $4,431, which is recorded in Other non-current liabilities on the Consolidated Balance Sheet. The Company recorded a net loss of $57 and $113 in AOCI during the second quarter and six months ended December 29, 2023. The Company recorded a net gain of $48 and $96 in AOCI during the second quarter and six months ended December 30, 2022. The Company recognized net periodic benefit costs of $208 and $415 associated with the Plan for the second quarter and six months ended December 29, 2023, respectively. The Company recognized net periodic benefit costs of $220 and $441 associated with the Plan for the second quarter and six months ended December 30, 2022, respectively. The Company's total expected employer contributions to the Plan during fiscal 2024 are $1,133.
401(k) Plan
The Company maintains a qualified 401(k) plan (the “401(k) Plan”) for its U.S. employees and matches participants' eligible annual compensation up to 6% in Company stock. The Company may also make optional contributions to the plan for any plan year at its discretion. The Company had $3,270 and $2,705 of capitalized stock-based 401(k) matching compensation expense on the Consolidated Balance Sheet at December 29, 2023 and June 30, 2023, 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 second quarter and six months ended December 29, 2023, the Company recognized share-based matching contributions related to the 401(k) plan of $2,811 and $7,652, as compared to $3,822 and $6,427 during the second quarter and six months ended December 30, 2022.

J.Stock-Based Compensation
STOCK INCENTIVE PLANS
At December 29, 2023, 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 (other than by exercise) of awards under the 2005 Plan. The foregoing does not affect any outstanding awards under the 2005 Plan, which remain in full force and effect in accordance with their terms. The 2018 Plan provides for the grant of non-qualified and incentive stock options, restricted stock, stock appreciation rights and deferred stock awards to employees and non-employees. Stock options must be granted with an exercise price of not less than 100% of the fair value of the Company’s common stock on the date of grant and the options generally have a term of seven years. There were 4,110 available shares for future grant under the 2018 Plan at December 29, 2023.
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
At December 29, 2023, the aggregate number of shares authorized for issuance under the Company’s 1997 Employee Stock Purchase Plan, as amended and restated (“ESPP”), is 2,300 shares, including 500 shares approved by the Company's shareholders on October 28, 2020. Under the ESPP, rights are granted to purchase shares of common stock at 85% of the lesser of the market value of such shares at either the beginning or the end of each six-month offering period. The ESPP permits employees to purchase common stock through payroll deductions, which may not exceed 10% of an employee’s compensation as defined in the ESPP. There were 107 and 57 shares issued under the ESPP during the six months ended December 29, 2023 and December 30, 2022, respectively. Shares available for future purchase under the ESPP totaled 60 at December 29, 2023.
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 New Hire Option is granted in four (4) tranches as follows: (w) 233,500 shares of the Company’s common stock with an exercise price equal to $42.00 (“Tranche 1”); (x) 233,500 shares of the Company’s common stock with an exercise price equal to $43.00 (“Tranche 2”); (y) 233,500 shares of the Company’s common stock with an exercise price equal to $46.00 (“Tranche 3”); and (z) 233,500 shares of the Company’s common stock with an exercise price equal to $49.00 (“Tranche 4”). Tranche 1 and Tranche 2 shall become vested and exercisable on the third anniversary of August 17, 2023 ("the Initial Grant Date") (subject to the Executive’s continued employment through such date) and shall expire on the fourth anniversary of the Initial Grant Date. Tranche 3 and Tranche 4 shall become vested and exercisable on the fourth anniversary of the Initial Grant Date (subject to the Executive’s continued employment through such date) and shall expire on the fifth anniversary of the Initial Grant Date.

There were no options vested or exercised during the second quarter ended December 29, 2023. Non-vested stock options are subject to the risk of forfeiture until the fulfillment of specified conditions. As of December 29, 2023, there was $10,609 of total unrecognized compensation cost related to non-vested options granted that is expected to be recognized over a weighted-average period 3.18 years from December 29, 2023.
The Company uses the Black-Scholes valuation model for estimating the fair value on the date of grant of stock options. The Company calculated the fair values of the options grants using the following weighted-average assumptions:
Second Quarter Ended
December 29, 2023
Expected volatility45 %
Expected term4 years
Risk-free interest rate4.44 %
Expected dividend yield %
Weighted-average grant date fair value per share$12.71 
The expected volatility of options granted has been determined using a weighted average of the historical volatility of the Company’s stock for a period equal to the expected life of the option. The expected life of options has been determined using the average of the contractual term and the weighted average vesting term of the options. The risk-free interest rate is based on a
15


zero-coupon U.S. treasury instrument whose term is consistent with the expected life of the stock options. The Company has not paid and does not anticipate paying cash dividends on its shares of common stock; therefore, the expected dividend yield is assumed to be zero. The Company applied an estimated annual forfeiture rate based on historical averages in determining the expense recorded in each period. There were no stock options granted during fiscal year ended June 30, 2023.

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 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 subsystems which combine technologies into more complex diverse products has shifted. The following tables present revenue consistent with the Company's strategy of expanding its technological capabilities and program content. As additional information related to the Company’s products by end user, application, product grouping and/or platform is attained, the categorization of these products can vary over time. When this occurs, the Company reclassifies revenue by end user, application, product grouping and/or platform for prior periods. Such reclassifications typically do not materially change the underlying trends of results within each revenue category.
The following table presents the Company's net revenue by end user for the periods presented:

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. 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 standard that MassDEP published for PFAS in October 2020. The Company has not been contacted by NTS or MassDEP since the dates discussed above. It is too early to determine what responsibility, if any, the Company 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 entitlement 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 the arbitration trial has been scheduled for mid-December 2024. 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 and compensation during the dispute. If instead the arbitrator rules for the former CEO, the Company could be liable for up to approximately $12,900, based on the closing price of the Company's common stock on June 26, 2023, plus legal fees and expenses and compensation during dispute, for accelerated equity vesting, severance, and other benefits under the CIC Agreement. 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 $12,900, plus costs and attorneys’ fees 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 asserts 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 alleges that the Company's public disclosures in SEC filings and on earnings calls were false and/or misleading. 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, are indemnified by the Company for this matter. The Company believes the claims in the complaint 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 December 29, 2023, 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 $122,449.
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.
20


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 December 29, 2023, the fair value of the September 2023 Swap was a liability of $8,710 and is included within Other non-current liabilities in the Company's Consolidated Balance Sheets.
During the second quarter and six months ended December 29, 2023, the Company amortized a total of $881 and $1,220, respectively, 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 December 29, 2023, 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.
On January 12, 2024, the Company initiated and approved a workforce reduction that will eliminate approximately 100 positions, resulting in expected restructuring charges of approximately $10,000 - $12,000. These charges are for employee separation costs and will be classified as Restructuring and other charges within the Consolidated Statements of Operations and Comprehensive Loss for the fiscal quarter ending March 29, 2024.

OVERVIEW
Mercury Systems, Inc. is a technology company that delivers processing power for the most demanding aerospace and defense missions. Headquartered in Andover, Massachusetts, our end-to-end processing platform enables a broad range of aerospace and defense programs, optimized for mission success in some of the most challenging and demanding environments. Processing technologies that comprise our platform include signal solutions, display, software applications, networking, storage and secure processing. Our innovative solutions are mission-ready, trusted and secure, software-defined and open and modular meeting our customers’ cost and schedule needs today by allowing them to use or modify our products to suit their mission. Customers access our solutions via the Mercury Processing Platform, which encompasses the broad scope of our investments in technologies, companies, products, services and the expertise of our people. Ultimately, we connect our customers to what matters most to them. We connect commercial technology to defense, people to data and partners to opportunities. And, at the most human level, we connect what we do to our customers’ missions; supporting the people for whom safety, security and protecting freedom are of paramount importance.
As a leading manufacturer of essential components, products, modules and subsystems, we sell to defense prime contractors, the U.S. government and original equipment manufacturers (“OEM”) commercial aerospace companies. Mercury has built a trusted, robust portfolio of proven product solutions, leveraging the most advanced commercial silicon technologies and purpose-built to exceed the performance needs of our defense and commercial customers. Customers add their own applications and algorithms to our specialized, secure and innovative products and pre-integrated solutions. This allows them to complete their full system by integrating with their platform, the sensor technology and, increasingly, the processing from Mercury. Our products and solutions are deployed in more than 300 programs with over 25 different defense prime contractors and commercial aviation customers.
Mercury’s business model accelerates the process of making new technology profoundly more accessible to our customers by bridging the gap between commercial technology and aerospace and defense applications on time constraints that matter.
22


Our long-standing deep relationships with leading high-tech and other commercial companies, coupled with our high level of research and development (“R&D”) investments on a percentage basis and industry-leading trusted and secure design and manufacturing capabilities, are the foundational tenets of this model. We are leading the development and adaptation of commercial technology for aerospace and defense solutions. From chip-scale to system scale and from data, including radio frequency (“RF”) to digital to decision, we make mission-critical technologies safe, secure, affordable and relevant for our customers.
Our capabilities, technology, people and R&D investment strategy combine to differentiate Mercury in our industry. We maintain our technological edge by investing in critical capabilities and intellectual property (“IP” or “building blocks”) in processing, leveraging open standards and open architectures to adapt quickly those building blocks into solutions for highly data-intensive applications, including emerging needs in areas such as artificial intelligence (“AI”).
Our mission critical solutions are deployed by our customers for a variety of applications including command, control, communications, computers, intelligence, surveillance and reconnaissance (“C4ISR”), electronic intelligence, mission computing avionics, electro-optical/infrared (“EO/IR”), electronic warfare, weapons and missile defense, hypersonics and radar.
Since we conduct much of our business with our defense customers via commercial items, requests by customers are a primary driver of revenue fluctuations from quarter to quarter. Customers specify delivery date requirements that coincide with their need for our products. Because these customers may use our products in connection with a variety of defense programs or other projects of different sizes and durations, a customer’s orders for one quarter generally do not indicate a trend for future orders by that customer. Additionally, order patterns do not necessarily correlate amongst customers and, therefore, we generally cannot identify sequential quarterly trends.
As of December 29, 2023, we had 2,550 employees. We employ hardware and software architects and design engineers, primarily engaged in engineering and research and product development activities to achieve our objectives to fully capitalize upon and maintain our technological leads in the high-performance, real-time sensor processing industry and in mission computing, platform management and other safety-critical applications. Our talent attraction, engagement and retention is critical to execute on our long-term strategy. We invest in our culture and values to drive employee engagement that turns ideas into action, delivering trusted and secure solutions at the speed of innovation. We believe that our success depends on our ability to embrace diversity company-wide and realize the benefits of a diverse workforce that includes a greater variety of solutions to problems, a broader collection of skills and experiences and an array of viewpoints to consider. We are strongly focused on providing an inclusive environment that respects the diversity of the world. We believe that the workforce required to grow our business and deliver creative solutions must be rich in diversity of thought, experience and culture. Our diversity and inclusion initiatives focus on building and maintaining the talent that will create cohesive and collaborative teams that drive innovation. We believe that these values will help our employees realize their full potentials at work to provide Innovation That Matters®.
Our consolidated revenues, net loss, diluted net loss per share, adjusted loss per share (“adjusted EPS”), and adjusted EBITDA for the second quarter ended December 29, 2023 were $197.5 million, ($45.6) million, ($0.79), ($0.42), and ($21.3) million, respectively. Our consolidated revenues, net loss, diluted net loss per share, adjusted EPS, and adjusted EBITDA for the six months ended December 29, 2023 were $378.5 million, ($82.3) million, ($1.44), ($0.66), and ($19.4) million, respectively. See the Non-GAAP Financial Measures section for a reconciliation to our most directly comparable GAAP financial measures.

REVENUES
Total revenues decreased $32.1 million, or 14.0%, to $197.5 million during the second quarter ended December 29, 2023, as compared to $229.6 million during the second quarter ended December 30, 2022. Revenues decreased year over year as we continue to prioritize resources to execute our challenged programs, transition from our higher mix of development programs and aim to better align our operating cadence with prudent working capital management. As a result, we are experiencing a temporary volume shift in our total revenue, especially our over time revenue which decreased by approximately $25.1 million. We expect this trend to continue through the remainder of fiscal 2024. Over time revenue represented 53% of total revenues during the second quarter ended December 29, 2023, as compared to 56% of total revenues during the second quarter ended December 30, 2022.
Specifically, with regard to our challenged programs which are recognized over time, we have recognized a majority of the revenue and related cost as we acquired material and applied labor over the period of performance to progress these programs in prior periods. As we continue to resolve technical challenges and complete these programs, which consumes a significant amount of operational capacity, the remaining revenues on these challenged programs are recognized, however these revenues represent a very small proportion of the total contract value. In addition, we adjusted our estimates at completion for incremental technical and execution costs in the quarter, especially as related to one of our challenged programs as well as certain other development and production programs resulting in a cumulative adjustment to reduce revenues in the second quarter. In addition, as we transition our operating cadence with a goal of more properly balancing our material purchases with contract awards and resource availability to drive better working capital results, we are experiencing a near-term revenue timing dynamic.
We experienced decreases across each product grouping during the second quarter ended December 29, 2023 when compared to the prior period; modules and sub-assemblies, components, and integrated subsystems, decreased $26.5 million, $3.7 million, and $1.9 million, respectively. The decrease in total revenue was primarily driven by the radar, other sensor and
24


effector and electronic warfare end applications decreases of $30.5 million, $6.7 million, and $5.3 million, respectively, partially offset by increases to C4I end applications of $11.7 million. The decrease in total revenue was also driven by lower Naval and Other platforms of $18.3 million and $17.9 million, respectively, partially offset by increases to airborne platforms of $4.9 million. The largest program decreases were related to the AEGIS program, a secure processing program, and the THAAD program, partially offset by increases to a large C4I program and the F/A-18 program when compared to the prior period. There were no programs comprising 10% or more of our revenues for the second quarters ended December 29, 2023 or December 30, 2022.
GROSS MARGIN
Gross margin was 16.0% for the second quarter ended December 29, 2023, a decrease of 1930 basis points from the 35.3% gross margin realized during the second quarter ended December 30, 2022. The lower gross margin was driven by cost growth impacts and higher manufacturing adjustments, primarily related to inventory reserves and scrap. The growth in estimated costs to complete during fiscal 2024 has significantly reduced the overall margins recognized on the affected programs through completion. Program cost growth of approximately $30.6 million was recorded in the quarter resulting in an incremental impact of approximately $23.3 million to gross margin, or 1230 basis points, when compared to the prior period. Approximately $13.7 million of total cost growth impact in the quarter was attributable to the approximately 20 challenged programs, of which $12.6 million related to one program. The remaining $16.9 million was incurred across certain other development and production programs based on facts and circumstances in the quarter. The decrease in gross margin was also attributable to higher manufacturing adjustments of approximately $13.3 million related to inventory reserves and scrap. The increase in inventory reserves was related to specifically identified excess and obsolete inventory primarily resulting from a shift in customer demand for our next generation product offering. In addition, we are actively marketing and selling certain of our slow moving inventory with certain parts expected to be at a discount. The increase in scrap was primarily a result of higher levels of discrepant material especially as related to the common processing architecture across several of our remaining challenged programs. We have several initiatives underway to address more efficient and cost-effective producibility of these subsystems.
SELLING, GENERAL AND ADMINISTRATIVE
Selling, general and administrative expenses decreased $0.6 million, or 1.3%, to $44.5 million during the second quarter ended December 29, 2023, as compared to $45.1 million in the second quarter ended December 30, 2022. The decrease was primarily driven by the reduction in force initiated on August 9, 2023, resulting in lower compensation costs including $2.5 million of stock compensation expense, $1.3 million of bonus expense, as well as a reduction in controllable spend. These decreases were partially offset by contract asset write-offs of $4.8 million as a result of negotiating settlement terms with our customers to reduce scope, or otherwise exit contracts, especially as related to certain challenged programs.
RESEARCH AND DEVELOPMENT
Research and development expenses increased $1.6 million, or 5.8%, to $28.5 million during the second quarter ended December 29, 2023, as compared to $26.9 million during the second quarter ended December 30, 2022. The increase during the second quarter ended December 29, 2023 was driven by higher compensation costs of $1.3 million and $1.2 million of incremental R&D spend on equipment and supplies and outside services, partially offset by lower bonus expense of $0.8 million as compared to the second quarter ended December 30, 2022.
AMORTIZATION OF INTANGIBLE ASSETS
Amortization of intangible assets decreased $1.3 million to $12.3 million during the second quarter ended December 29, 2023, as compared to $13.5 million during the second quarter ended December 30, 2022, primarily due to the backlog intangible from our Avalex acquisition being fully amortized in fiscal 2023.
RESTRUCTURING AND OTHER CHARGES
There was an immaterial amount of restructuring and other charges during the second quarter ended December 29, 2023. Restructuring and other charges during the second quarter ended December 30, 2022 included $1.0 million of costs related to facility optimization efforts associated with 1MPACT, including $0.8 million related to lease asset impairment, as well as $0.6 million related to severance costs and the remaining $0.4 million related to third party consulting costs associated with 1MPACT.

On January 12, 2024, we initiated and approved a workforce reduction that will eliminate approximately 100 positions, resulting in expected restructuring charges of approximately $10 - 12 million. All of the restructuring and other charges will be 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.
ACQUISITION COSTS AND OTHER RELATED EXPENSES
There was an immaterial amount of acquisition costs and other related expenses during the second quarter ended December 29, 2023. The acquisition costs and other related expenses during the second quarter ended December 30, 2022 were primarily related to $0.6 million for third-party advisory fees in connection with engagements by activist investors and other acquisition related costs.
INTEREST EXPENSE
We incurred $8.7 million of interest expense during the second quarter ended December 29, 2023, as compared to $6.6 million during the second quarter ended December 30, 2022. The increase was driven by a higher interest rate and higher average outstanding borrowings during the period on our existing credit facility (the "Revolver").
