UNAUDITED SUPPLEMENTAL INFORMATION RECONCILIATION OF GAAP TO NON-GAAP MEASURES
(In thousands, except per share data)

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 which may be 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 lines of business. 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 Fourth Quarter and Fiscal 2026 Results, Page 10

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, often occur in periods other than the period of activity, 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.
 
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 direct 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, 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(1). Adjusted EPS expresses adjusted income on a per share basis using weighted average diluted shares outstanding.

© Mercury Systems, Inc. /Mercury Proprietary/No Tech Data/ Forward-looking safe harbor statement This presentation contains certain forward-looking statements, as that term is defined in the Private Securities Litigation Reform Act of 1995, including those relating to the Company's focus on enhanced execution of the Company's strategic plan. You can identify these statements by the words “may,” “will,” “could,” “should,” “would,” “plans,” “expects,” “anticipates,” “continue,” “estimate,” “project,” “intend,” “likely,” “forecast,” “probable,” “potential,” and similar expressions. These forward-looking statements involve risks and uncertainties that could cause actual results to differ materially from those projected or anticipated. Such risks and uncertainties include, but are not limited to, cost increases, our inability to increase production and deliver products on time and with appropriate quality, continued funding of defense programs, the timing and amounts of such funding, general economic and business conditions, including unforeseen weakness in the Company’s markets, effects of any U.S. federal government shutdown or extended continuing resolution, effects of increasingly volatile geopolitical events and regional conflicts, competition, changes in technology and methods of marketing, delays in or cost increases related to completing development, engineering and manufacturing programs, changes in customer order patterns, changes in product mix, continued success in technological advances and delivering technological innovations, changes in, or in the U.S. government’s interpretation of, federal export control or procurement rules and regulations, including tariffs, changes in, or in the interpretation or enforcement of, environmental rules and regulations, market acceptance of the Company's products, shortages or delays in receiving components, supply chain delays or volatility for critical components, production delays or unanticipated expenses including due to quality issues or manufacturing execution issues, failure to meet contractual performance specifications, adherence to required manufacturing standards, capacity underutilization, increases in scrap or inventory write-offs, failure to achieve or maintain manufacturing quality certifications, such as AS9100, failure to achieve or maintain qualified business systems, such as those required by the DFARS, adverse findings in government audits or investigations, the impact of supply chain disruption, inflation and labor shortages, among other things, on program execution and the resulting effect on customer satisfaction, inability to fully realize the expected benefits from acquisitions, restructurings and operational efficiency initiatives or delays in realizing such benefits, challenges in integrating acquired businesses and achieving anticipated synergies, effects of shareholder activism, increases in interest rates, changes to industrial security and cyber-security regulations and requirements and impacts from any cyber or insider threat events, including the risks from heightened, persistent, and increasingly sophisticated nation-state level cyberattacks and emerging threats associated with agentic AI-enabled cyber tools, changes in tax rates or tax regulations, changes to interest rate swaps or other cash flow hedging arrangements, changes to generally accepted accounting principles, difficulties in retaining key employees and customers, litigation, including the state law claim related to our settled federal securities class action lawsuit, unanticipated costs under fixed-price service and system integration engagements, and various other factors beyond our control. These risks and uncertainties also include such additional risk factors as are discussed in the Company's filings with the U.S. Securities and Exchange Commission, including its Annual Report on Form 10-K for the fiscal year ended July 3, 2026 and subsequent Quarterly Reports on Form 10-Q and Current Reports on Form 8-K. The Company cautions readers not to place undue reliance upon any such forward-looking statements, which speak only as of the date made. 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, and free cash flow, 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. 2


 
© Mercury Systems, Inc. /Mercury Proprietary/No Tech Data/ Today’s call ▪ Opening remarks on business and results ▪ Update on our four priorities ▪ Performance expectations for FY27 and beyond ▪ Q&A 3


 
© Mercury Systems, Inc. /Mercury Proprietary/No Tech Data/ Business and results ▪ Our Q4 FY26 results reflected robust organic growth and margin expansion: • Record bookings of $660M, up 93.1% year-over-year and nearly double our previous record bookings quarter; a 2.3 book-to-bill, record backlog of over $1.9B, and record next-12-month backlog of $1.0B. • Record Q4 FY26 revenue of $290M. • Q4 FY26 adjusted EBITDA of $49M and adjusted EBITDA margin of 16.7%. • Free cash flow of $29M. Ended Q4 FY26 with $227M of net debt, down 19.5% year-over-year. ▪ These results reflect ongoing focus on our four priority areas with highlights that include: • Solid execution across our broad portfolio leading to full-year FY26 organic revenue growth of 7.9% and adjusted EBITDA growth of 25.7%. • Year-over-year growth in backlog and next-12-month backlog of 38.4% and 23.3%, respectively. • An increase of 217 basis points year-over-year in full-year adjusted EBITDA margin; and • Continued progress on free cash flow drivers with net working capital down 4.0% year-over-year while revenue grew 7.9%. 4


 
© Mercury Systems, Inc. /Mercury Proprietary/No Tech Data/ Driving performance excellence ▪ Focused on sound execution on development programs, delivering for our customers across our portfolio, and scaling efficiently on numerous programs transitioning to higher volume production. • In Q4, we ramped up across a number of programs and generated record quarterly revenue. • Our over time revenue in Q4, up 23.6% year-over-year, was the highest in 15 quarters, driven largely by the receipt of material which we believe is an indicator that we are better aligning our supply chain with the increased organic growth we are seeing in several areas across the business. ▪ Our domestic revenue, representing approximately 85.8% of our FY26 revenue, grew 13.0% organically year-over-year. ▪ Continue efforts to expand capacity, increase automation, and consolidate sub-scale sites in our ongoing efforts to drive scalability and efficiency: • Recently announced a strategic agreement with Palantir to leverage AI software to enhance material planning and factory operations in an effort to improve backlog conversion and deliver critical technologies to the warfighter. 5


 
© Mercury Systems, Inc. /Mercury Proprietary/No Tech Data/ Driving organic growth ▪ Record quarter with $660M of bookings resulting in record fiscal year bookings of $1.5B, up 49.8% year- over-year, and a book-to-bill of 1.57 for the year. • Record total backlog approaching $2.0B is also providing enhanced visibility as we enter FY27 and into FY28. ▪ Strength in Q4 bookings was broad-based, with significant production awards across our products and solutions in Common Processing Architecture (CPA), effectors, airborne applications, space and missile defense. • Largest quarter ever for CPA bookings which we believe reflects the differentiation of our CPA solutions and reinforces our confidence in the growth prospects of this area. • The quarter also included significant bookings related to securing memory to support future production requirements across a number of advanced defense platforms. • Beginning to see the favorable impacts of the defense budgetary environment leading to a number of multi-year customer commitments. ▪ Continue to see the potential for higher demand on multiple programs across our portfolio, including space, munitions, missile defense, and our CPA, driven by increased defense budgets globally and domestic priorities. 6


 
© Mercury Systems, Inc. /Mercury Proprietary/No Tech Data/ Expanding margins ▪ In our efforts to progress toward our targeted adjusted EBITDA margins in the low to mid 20% range, we remain focused on the following drivers: • Backlog margin expansion as we convert low-margin backlog and add new bookings aligned with our target margin profile. • Ongoing initiatives to further simplify, automate, and optimize our operations. • Driving organic growth to increase positive operating leverage. ▪ Gross margin for FY26 of 28.6% was up 70 basis points year-over-year, consistent with our expectation that average backlog margin will continue to increase as we convert legacy lower-margin backlog and bring in new bookings that we believe will be in line with our targeted margin profile. ▪ FY26 operating expenses are down year-over-year as a percent of our revenue reflecting our ongoing focus to drive efficiencies and enable positive operating leverage as we accelerate organic growth. ▪ Full year adjusted EBITDA margin of 15.3% was in line with our expectations and up 217 basis points year-over-year. 7


 
© Mercury Systems, Inc. /Mercury Proprietary/No Tech Data/ Driving improved free cash flow conversion and release ▪ Continue to make progress on drivers of free cash flow. Net working capital at approximately $431M is down $18M year-over-year. ▪ Full year free cash flow of $68M led to net debt of $227M at the end of Q4, which we reduced by $55M year-over-year. ▪ Continuous improvement related to program execution, demand planning, and supply chain management, along with strong balance sheet flexibility, positions us well to drive organic growth and capitalize on any additional potential market tailwinds. 8


 
© Mercury Systems, Inc. /Mercury Proprietary/No Tech Data/ Expectations for FY27 and beyond* ▪ Increasing targeted organic revenue growth to low double digits, while maintaining targeted adjusted EBITDA margin in the low to mid 20s and targeted FCF conversion of 50%. ▪ For FY27, expect revenue growth approaching double digits year-over-year with total revenue approaching $1.1B. • Anticipate Q1 FY27 revenue to be the lowest of the year and up high single digits year-over-year, with revenue increasing through the balance of the year. ▪ Expect adjusted EBITDA margin in the high-teens and adjusted EBITDA approaching $200M for the full year, reflecting nearly 30% year-over-year growth. • Expect adjusted EBITDA margin to generally increase through the year, with Q1 FY27 adjusted EBITDA margin expected to be in-line with Q1 FY26. ▪ Amidst increased demand, we plan to make targeted investments in inventory, automation, and factory optimization to drive organic growth. • For the full year, we are anticipating FY27 free cash flow conversion beneath our 50% target, approaching 35%, with free cash flow in the second half expected to be higher than in the first half. • Expect Q1 to be a larger outflow than normal, primarily reflecting the receipt of materials to support our growth outlook and the defense spending tailwinds we see ahead. 9


 
© Mercury Systems, Inc. /Mercury Proprietary/No Tech Data/ Expectations for FY27 and beyond* - continued ▪ In our initial view of FY28, our reference point for top-line organic growth is in the low double digits, for adjusted EBITDA margin in-line with the low end of our target margin profile, and for free cash flow a return towards conversion in line with our target. ▪ Outlook for FY27 and FY28 incorporates a limited set of tailwinds that have materialized in firm bookings. • Does not incorporate the benefit of potential additional tailwinds that could occur on a number of production programs across our portfolio, including our CPA, effectors, airborne applications, space, and missile defense. • Additionally, outlook does not incorporate any benefit from the Palantir partnership or other automation efforts across our organization to improve backlog conversion. • We believe any such improvements may translate into higher organic growth and adjusted EBITDA margin representing potential upside to our outlook. 10 * FY28 reference points, along with our target profile, should not be construed as financial guidance and speak only as of today. They illustrate the financial profile the business could achieve based on the factors referenced in the forward-looking safe harbor statement, including our ability to convert backlog to revenue and gain additional orders beyond current backlog. These factors may materially affect whether we reach these reference points or target profile.
