**Item 2.02.&nbsp;&nbsp;&nbsp;&nbsp;Results of Operations and Financial Condition.**

On January 31, 2023, Mercury Systems, Inc. (the "Company") issued a press release and an earnings presentation regarding its financial results for the second quarter of fiscal 2023 ended December 30, 2022. The Company's earnings release and earnings presentation are attached as exhibits 99.1 and 99.3 to this Current Report on Form 8-K and incorporated by reference herein.

&nbsp;&nbsp;&nbsp;&nbsp;Information in Item 2.02 of this Current Report on Form 8-K and the exhibits 99.1 and 99.3 attached hereto shall not be deemed "filed" for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the "Exchange Act") or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, regardless of any general incorporation language in such filing.

**Use of Non-GAAP Financial Measures**

&nbsp;&nbsp;&nbsp;&nbsp;In addition to reporting financial results in accordance with generally accepted accounting principles, or GAAP, the Company provides adjusted EBITDA, adjusted income, adjusted EPS, free cash flow, organic revenue and acquired revenue, which are non-GAAP financial measures. Adjusted EBITDA, adjusted income, and adjusted EPS exclude certain non-cash and other specified charges. The Company believes these non-GAAP financial measures are useful to help investors more completely understand its past financial performance and prospects for the future. However, the presentation of these non-GAAP financial measures is not meant to be considered in isolation or as a substitute for financial information provided in accordance with GAAP. Management believes these non-GAAP financial measures assist in providing a more complete understanding of the Company's underlying operational results and trends, and management uses these measures along with the corresponding GAAP financial measures to manage the Company's business, to evaluate its performance compared to prior periods and the marketplace, and to establish operational goals.

**Item 5.02.&nbsp;&nbsp;&nbsp;&nbsp;Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.**

The Company's Board of Directors has appointed Michelle M. McCarthy as the Company's interim Chief Financial Officer and Treasurer effective February 17, 2023, in addition to her current duties as the Company's Senior Vice President, Chief Accounting Officer. On January 25, 2023, Michael D. Ruppert, the Company's Executive Vice President, Chief Financial Officer, and Treasurer informed the Company that he will be departing on February 17, 2023. The Company has initiated a search for a successor Chief Financial Officer. Mr. Ruppert's departure is not related to any issues or disagreements on the Company's financial statement disclosures or accounting policies or practices.

Ms. McCarthy, age 42, joined the Company in 2018 as its Vice President, Chief Accounting Officer. She was promoted to Senior Vice President, Chief Accounting Officer in 2022. Prior to joining the Company, Ms. McCarthy was Corporate Controller of Analog Devices, Inc., a publicly traded, global high-performance analog technology company, from 2015 to 2018, and she served as Assistant Corporate Controller at Analog Devices from 2011 to 2015. Prior to that, Ms. McCarthy served in various positions throughout the assurance practice at Ernst & Young LLP. Ms. McCarthy is a Certified Public Accountant.

Ms. McCarthy will not receive any additional compensation for assuming the role of interim Chief Financial Officer and Treasurer other than her being awarded a $200,000 restricted stock award effective February 15, 2023, with four-year time-based vesting. Consistent with the Company's prior practice for granting equity awards, the number of shares to be granted to Ms. McCarthy will be determined by dividing the target value by the average closing price of Mercury's common stock during the 30 calendar days prior to February 15, 2023. In the event that Ms. McCarthy receives additional compensation for this interim role beyond the equity award discussed herein, the Company will file an amendment to this Current Report on Form 8-K with a summary of such compensation.

There are no family relationships between Ms. McCarthy and any director or executive officer of the Company, and she has no direct or indirect material interest in any transaction required to be disclosed pursuant to Item 404(a) of Regulation S-K.

**Item 7.01.&nbsp;&nbsp;&nbsp;&nbsp;Regulation FD Disclosure.**

**Mercury Systems Reports Second Quarter Fiscal 2023 Results; Initiates Review of Strategic Alternatives**

**Second Quarter Highlights Include:**

**Bookings of $270.3M yielding book-to-bill of 1.18**

**Record backlog of $1.12 billion**

**Revenues increased 4% over prior year with positive organic growth**

**Generated positive cash flow**

**ANDOVER, Mass. January 31, 2023** Mercury Systems, Inc. (NASDAQ: MRCY, www.mrcy.com), reported operating results for the second quarter of fiscal 2023, ended December 30, 2022.

**Management Comments**

"In the second quarter, the Company generated positive organic growth and cash flow," said Mark Aslett, Mercury's President and Chief Executive Officer. "Driven by accelerated bookings growth, our book-to-bill was 1.18 for the quarter and backlog grew to a record $1.12 billion. Looking forward to the second half of fiscal 2023, we expect to see continued revenue growth, higher margins and increased profitability and as a result, we're maintaining our full-year guidance for revenue and adjusted EBITDA."

"We see a favorable demand environment ahead even as we experienced some customer funding delays and continued supply chain challenges that are affecting the timing of conversion to revenue. Mercury is well-positioned to benefit from growth in U.S. and international defense spending, the increasing electronification of new and existing platforms, and ongoing supply chain delayering and reshoring."

**Recent Highlights**

January – Mercury announced that Vivek Upadhyaya joined the company as Vice President of Finance to lead the corporate finance team and be responsible for forecasting and analysis as well as internal management reporting. Upadhyaya was most recently Chief Financial Officer, Treasurer, and Chief Information Officer of Leonardo Electronics U.S., Inc., a subsidiary of Leonardo and supplier of laser and electronic solutions to the defense, security, and medical industries.

January – Mercury introduced a new COTS open-architecture board that delivers the latest commercial signal processing technology for aerospace and defense applications, driving higher performance from a smaller form factor. The DRF3182 Direct RF Processing Module is the first standard product purpose-built for the aerospace and defense industry that leverages Intel's new Stratix® 10 AX SoC field programmable gate array (FPGA), which adds a key capability to the Mercury Processing Platform by enabling the direct digitization and processing of broadband RF signals.

November — The U.S. Army announced that Mercury was one of three finalists awarded cash prizes to drive technology innovations that facilitate the convergence of warfighting platforms. Mercury presented a prototype for improving the C4ISR/Electronic Warfare Modular Open Suite of Standards as part of xTechCMFF Integration Fest, an event hosted by the Army xTech Program.

Mercury Reports Second Quarter Fiscal 2023 Results, Page 5

November – Mercury introduced a new radiation-tolerant version of its proven 8GB DDR4 memory component that sets a new bar for performance in data-intensive processing applications in space. As space systems become more complex, new capabilities and requirements necessitate high-density memory capabilities to complement greater processing power. And as space systems are increasingly developed with smaller form factors, Mercury's 8GB DDR4 components offer 75% space savings compared to alternative memory options.

October – Mercury announced that its new mPOD, a rapidly reprogrammable electronic attack training system designed to train pilots using realistic, near-peer jamming capabilities, successfully completed initial flight testing and is available for order. Tactical Air Support, a leader in commercial air services, tactical aviation training, and technical advisory services for U.S. military and international partners, oversaw three days of flight testing that ran beyond visual range tactical intercept training engagements replicating adversary tactics. F-5 aircraft equipped with Mercury's mPOD training system successfully broke, delayed, and denied opposing fighter radar locks, created multiple false targets on the opposing fighter radar, and performed other electronic attack techniques.

October – Mercury announced that the mission computer it built for the Airbus A330 MRTT allowed the tanker to receive the world's first certification for automatic air-to-air refueling boom operations. Mercury Mission Systems International, located in Switzerland and Spain, delivered a purpose-built computer for Airbus based on the commercial off-the-shelf ROCK family of pre-integrated subsystem platforms that draw from a range of safety-certifiable modular COTS building blocks, addressing both the need for high-end video processing and the safety-criticality of the application.

Adjusted EBITDA, a non-GAAP measure for reporting financial performance, excludes the impact of certain items and, therefore, has not been calculated in accordance with GAAP. Management believes that exclusion of these items assists in providing a more complete understanding of the Company's underlying results and trends, and management uses these measures along with the corresponding GAAP financial measures to manage the Company's business, to evaluate its performance compared to prior periods and the marketplace, and to establish operational goals. The adjustments to calculate this non-GAAP financial measure, and the basis for such adjustments, are outlined below:

*Other non-operating adjustments*. The Company records other non-operating adjustments such as gains or losses on foreign currency remeasurement, investments and fixed asset sales or disposals among other adjustments. These adjustments may vary from period to period without any direct correlation to underlying operating performance.

*Interest income and expense*. The Company receives interest income on investments and incurs interest expense on loans, financing leases and other financing arrangements. These amounts may vary from period to period due to changes in cash and debt balances and interest rates driven by general market conditions or other circumstances outside of the normal course of the Company's operations.

*Income taxes*. The Company's GAAP tax expense can fluctuate materially from period to period due to tax adjustments that are not directly related to underlying operating performance or to the current period of operations.

*Depreciation*. The Company incurs depreciation expense related to capital assets purchased to support the ongoing operations of the business. These assets are recorded at cost or fair value and are depreciated using the straight-line method over the useful life of the asset. Purchases of such assets may vary significantly from period to period and without any direct correlation to underlying operating performance.

*Amortization of intangible assets.* The Company incurs amortization of intangible assets primarily as a result of acquired intangible assets such as backlog, customer relationships and completed technologies but also due to licenses, patents and other arrangements. These intangible assets are valued at the time of acquisition or upon receipt of right to use the asset, amortized over the requisite life and generally cannot be changed or influenced by management after acquisition.

*Restructuring and other charges.* The Company incurs restructuring and other charges in connection with management's decisions 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. Management believes these items are non-routine and may not be indicative of ongoing operating results.

*Impairment of long-lived assets.* The Company incurs impairment charges of long-lived assets based on events that may or may not be within the control of management. Management believes these items are outside the normal operations of the Company's business and are not indicative of ongoing operating results.

Mercury Reports Second Quarter Fiscal 2023 Results, Page 14

*Acquisition, financing and other third party costs*. The Company incurs transaction costs related to acquisition and potential acquisition opportunities, such as legal, accounting, and other third party advisory fees. The Company may also incur third-party costs, such as legal, banking, communications, proxy solicitation, and other third party advisory fees in connection with engagements by activist investors or unsolicited acquisition offers. Although the Company may incur such third-party costs and other related charges and adjustments, it is not indicative that any transaction will be consummated. Additionally, the Company incurs unused revolver and bank fees associated with maintaining its credit facility as well as non-cash financing expenses associated with obtaining its credit facility. Management believes these items are outside the normal operations of the Company's business and are not indicative of ongoing operating results.

*Fair value adjustments from purchase accounting.* As a result of applying purchase accounting rules to acquired assets and liabilities, certain fair value adjustments are recorded in the opening balance sheet of acquired companies. These adjustments are then reflected in the Company's income statements in periods subsequent to the acquisition. In addition, the impact of any changes to originally recorded contingent consideration amounts are reflected in the income statements in the period of the change. Management believes these items are outside the normal operations of the Company and are not indicative of ongoing operating results.

*Litigation and settlement income and expense.* The Company periodically receives income and incurs expenses related to pending claims and litigation and associated legal fees and potential case settlements and/or judgments. Although the Company may incur such costs and other related charges and adjustments, it is not indicative of any particular outcome until the matter is fully resolved. Management believes these items are outside the normal operations of the Company's business and are not indicative of ongoing operating results. The Company periodically receives warranty claims from customers and makes warranty claims towards its vendors and supply chain. Management believes the expenses and gains associated with these recurring warranty items are within the normal operations and operating cycle of the Company's business. Therefore, management deems no adjustments are necessary unless under extraordinary circumstances.

*COVID related expenses*. The Company incurred costs associated with the COVID pandemic. These costs relate primarily to enhanced compensation and benefits for employees as well as incremental supplies and services to support social distancing and mitigate the spread of COVID. These costs include expanded sick pay related to COVID, overtime, the Mercury Employee COVID Relief Fund, meals and other compensation-related expenses as well as ongoing testing for onsite employees. Management believes these items are outside the normal operations of the Company and are not indicative of ongoing operating results.

*Stock-based and other non-cash compensation expense.* The Company incurs expense related to stock-based compensation included in its GAAP presentation of cost of revenues, selling, general and administrative expense and research and development expense. The Company also incurs non-cash based compensation in the form of pension related expenses and matching contributions to its defined contribution plan. Although stock-based and other non-cash compensation is an expense of the Company and viewed as a form of compensation, these expenses vary in amount from period to period, and are affected by market forces that are difficult to predict and are not within the control of management, such as the market price and volatility of the Company's shares, risk-free interest rates and the expected term and forfeiture rates of the awards, as well as pension actuarial assumptions. Management believes that exclusion of these expenses allows comparisons of operating results to those of other companies, both public, private or foreign, that disclose non-GAAP financial measures that exclude stock-based compensation and other non-cash compensation.

Mercury uses adjusted EBITDA as an important indicator of the operating performance of its business. Management excludes the above-described items from its internal forecasts and models when establishing internal operating budgets, supplementing the financial results and forecasts reported to the Company's board of directors, determining a portion of bonus compensation for executive officers and other key employees based on operating performance, evaluating short-term and long-term operating trends in the Company's operations, and allocating resources to various

initiatives and operational requirements. The Company believes that adjusted EBITDA permits a comparative assessment of its operating performance, relative to its performance based on its GAAP results, while isolating the effects of charges that may vary from period to period without any correlation to underlying operating performance. The Company believes 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 its financial and operational decision-making. The Company believes that trends in its adjusted EBITDA are valuable indicators of its 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. The Company expects to continue to incur expenses similar to the adjusted EBITDA financial adjustments described above, and investors should not infer from the Company's presentation of this non-GAAP financial measure that these costs are unusual, infrequent or non-recurring.

The following table reconciles the most directly comparable GAAP financial measure to the non-GAAP financial measure.

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, and, therefore, has not been calculated in accordance with GAAP. Management believes free cash flow provides investors with an important perspective on cash available for investment and acquisitions after making capital investments required to support ongoing business operations and long-term value creation. The Company believes that trends in its free cash flow are valuable indicators of its 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. The Company expects to continue to incur expenditures similar to the free cash flow financial adjustment described above, and investors should not infer from the Company's presentation of this non-GAAP financial measure that these expenditures reflect all of the Company's obligations which require cash.

Adjusted income and adjusted earnings per share ("adjusted EPS") are non-GAAP measures for reporting financial performance, exclude the impact of certain items and, therefore, have not been calculated in accordance with GAAP. Management believes that exclusion of these items assists in providing a more complete understanding of the Company's underlying results and trends and allows for comparability with its 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. The Company uses these measures along with the corresponding GAAP financial measures to manage the Company's business and to evaluate its performance compared to prior periods and the marketplace. The Company defines adjusted income as 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, COVID related expenses, and stock-based and other non-cash compensation expense. The impact to income taxes includes the impact to the effective tax rate, current tax provision and deferred tax provision<sup>(1)</sup>. Adjusted EPS expresses adjusted income on a per share basis using weighted average diluted shares outstanding.

The following tables reconcile the most directly comparable GAAP financial measures to the non-GAAP financial measures.

| **UNAUDITED SUPPLEMENTAL INFORMATION RECONCILIATION OF GAAP TO NON-GAAP MEASURES** |
| (In thousands) |

---

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

The following table reconciles the most directly comparable GAAP financial measure to the non-GAAP financial measure.

The Company undertakes no obligation to update any forward-looking statement to reflect events or circumstances after the date on which such statement is made. Use of Non-GAAP (Generally Accepted Accounting Principles) Financial Measures In addition to reporting financial results in accordance with generally accepted accounting principles, or GAAP, the Company provides adjusted EBITDA, adjusted income, adjusted EPS, free cash flow, organic revenue and acquired revenue, which are non-GAAP financial measures. Adjusted EBITDA, adjusted income, and adjusted EPS exclude certain non-cash and other specified charges. The Company believes these non-GAAP financial measures are useful to help investors better understand its past financial performance and prospects for the future. However, these non-GAAP measures should not be considered in isolation or as a substitute for financial information provided in accordance with GAAP. Management believes these non-GAAP measures assist in providing a more complete understanding of the Company's underlying operational results and trends, and management uses these measures along with the corresponding GAAP financial measures to manage the Company's business, to evaluate its performance compared to prior periods and the marketplace, and to establish operational goals. A reconciliation of GAAP to non-GAAP financial results discussed in this presentation is contained in the Appendix hereto.

![](a2023q2earningspresentat016.jpg)© Mercury Systems, Inc.16 Adjusted EPS reconciliation Notes (1) Per share information is presented on a fully diluted basis. (2) Rounded amounts used. (3) 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. (4) All references in this presentation to the third quarter of fiscal 2023 are to the quarter ending March 31, 2023. All references in this presentation to the full fiscal 2023 are to the 52-week period ending June 30, 2023. (5) Adjusted earnings per share is calculated using diluted shares whereas Net loss is calculated using basic shares. There was no impact to the calculation of adjusted earnings per share as a result of this for the second quarters ended December 30, 2022 and December 31, 2021, respectively.
