Mercury Systems swings to $13.1M Q1 FY27 profit
Quarterly free cash flow was negative as Mercury raised its fiscal 2027 revenue, adjusted EBITDA and free-cash-flow conversion outlook.
Sentiment and the balance of points
Rhea-AI Sentiment reads the wording of the document, how positive or negative its language is on a 1 to 5 scale. The balance of points shown with the takes weighs what the document actually discloses, so the two can disagree, for example when a trial that missed its main goal is described in upbeat language.

How this balance works
Rhea-AI gives every point it takes from this document a weight. Minor counts 1, Moderate 3 and Major 9, so one Major point outweighs several Minor ones. The bar adds up the weights on each side, and when neither side holds more than 65% of the total the balance reads Mixed.
It reads the document as published, with the same rules for every company, and it does not look at what the market expected or at how the stock traded, so a point can be objectively good on a day the stock falls.
Rhea-AI Sentiment measures something else, the tone of the wording.

Key Terms
book-to-bill ratio, Adjusted EBITDA, free cash flow conversion, next-12-month backlog, +1 more
5 terms
book-to-bill ratio financial
"yielding a book-to-bill ratio of 1.46 for the quarter"
The book-to-bill ratio compares the value of new orders a company receives to the value of products it ships out or bills for over a certain period. If the ratio is above 1, it means the company is getting more orders than it is completing, which can indicate growth. If it's below 1, it suggests demand is slowing down.
Adjusted EBITDA financial
"Adjusted EBITDA is a non-GAAP financial measure"
Adjusted EBITDA is a way companies measure how much money they make from their core operations, like running a business, by removing certain costs or income that aren’t part of regular business activities. It helps investors see how well a company is doing without distractions from unusual expenses or gains, making it easier to compare companies or track performance over time.
free cash flow conversion financial
"FY27 free cash flow conversion approaching 40%"
Free cash flow conversion measures how effectively a company turns its reported profits into actual cash that can be used for growth, debt repayment, or dividends. It compares the cash generated after expenses to the company's net income, similar to how a person might compare their savings to their paycheck. High conversion indicates the company is efficient at translating profits into cash, which is important for investors assessing its financial health and flexibility.
next-12-month backlog financial
"record next-12-month backlog of over $1B"
net working capital financial
"net working capital down 60 basis points year-over-year"
Net working capital is the amount left when you subtract a company’s short-term bills (like accounts payable and short-term loans) from its short-term assets (cash, money owed to it, and inventory). Think of it as the cash cushion a business has to keep daily operations running — a bigger cushion means fewer short-term funding worries, while a small or negative number can signal pressure to raise cash or cut activity, which matters to investors assessing stability and short-term risk.

Use of Non-GAAP 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.

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.

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, including the implementation costs of cloud computing 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 or other transformation activities, including the analysis, evaluation, and planning of information system upgrades and/or deployments. 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 First Quarter Fiscal 2027 Results, Page 9
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.

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.

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 Q1 results reflect robust organic growth and margins that are in-line with our target profile: • Record Q1 bookings of $370M, up 48.0% year-over-year; a 1.46 book-to-bill, record backlog of $2.1B, and record next-12-month backlog of over $1B. • Record Q1 revenue of $253M. • Record Q1 adjusted EBITDA of $56M and adjusted EBITDA margin of 22.3%; and • Free cash out flow of $24M; better-than-expected performance. We ended Q1 with $232M of net debt, down 19.2% year-over- year. ▪ These Q1 results reflect relentless focus on our four priority areas, with highlights that include: • Solid execution across our portfolio leading to Q1 year-over-year organic revenue growth of 12.4% and adjusted EBITDA growth of 58.6%. • Year-over-year growth in backlog and next-12-month backlog of 44.7% and 27.9%, respectively. • An increase of 648 basis points year-over-year in adjusted EBITDA margin; and • Continued progress on free cash flow drivers with net working capital down 60 basis points year-over-year as a percent of trailing twelve-month revenue. 4
© Mercury Systems, Inc. /Mercury Proprietary/No Tech Data/ Driving performance excellence ▪ Focused on sound execution on development programs, delivering for our customers, and scaling efficiently on numerous programs transitioning to higher volume production. • In Q1, we ramped up across a number of programs generating record Q1 revenue and record trailing twelve-month revenue of just over $1B. • We believe Q1 revenue reflects increased linearity in the business enabled by an improving material posture. ▪ Our progress in scaling efficiently, combined with strong bookings and record backlog, have resulted in organic growth above our prior expectation for Q1, and a raised outlook for the full year. ▪ Beyond this solid performance, we continue efforts to expand capacity and increase automation to drive scalability and efficiency. 5
© Mercury Systems, Inc. /Mercury Proprietary/No Tech Data/ Driving organic growth ▪ Record first quarter with $370M of bookings, up 48.0% year-over-year, and a book-to-bill of 1.46 for the quarter. • Our trailing twelve-month bookings of $1.7B is the highest in the Company’s history, and our record total backlog of over $2B is providing enhanced visibility as we progress through FY27 and into FY28. ▪ Strength in Q1 bookings reflected demand across multiple areas of our portfolio. Importantly, we are also beginning to see some of the defense spending tailwinds we've discussed on past calls materialize in the form of earlier-than-expected bookings. • Effectors were a particular area of strength, with bookings increasing meaningfully year-over-year, including a significant production award for advanced weapons systems that expands Mercury's role on the program. We also received a follow -on production order supporting an established missile defense platform. • Radar bookings also increased year over year, supported by awards across multiple programs. • Electronic warfare was another area of strength, with bookings increasing significantly year over year, including a competiti ve takeaway on the F-35 program driven in part by improvements in our operational execution. • We also received notable awards across our common processing architecture and space-based tracking applications, including follow-on orders supporting existing satellite programs and additional funding associated with early-stage Golden Dome-related missile tracking capabilities. 6
© Mercury Systems, Inc. /Mercury Proprietary/No Tech Data/ Expanding margins ▪ In our efforts toward consistently delivering adjusted EBITDA margins in the low to mid 20s, we are focused on the following drivers: • Backlog margin expansion as we convert legacy lower-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 Q1 of 35.2% was up 730 basis points year-over-year reflecting a favorable mix in the quarter and improved average backlog margin. ▪ Q1 FY27 operating expenses are flat on an absolute basis and down year-over-year as a percent of revenue reflecting our ongoing focus to drive efficiencies and enable positive operating leverage with top-line growth. ▪ Quarterly adjusted EBITDA margin of 22.3% was ahead of our expectation and up 648 basis points year-over- year driven by the favorable mix in the quarter. We are encouraged by Q1 adjusted EBITDA margin which we believe is an early indication of our ability over time to consistently deliver results within our target margin profile. 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 $491M, while up $33M year-over-year, is down 60 basis points as a percent of trailing twelve- month revenue. ▪ Net debt of $232M at the end of the quarter is down $55M year-over-year. With a $100M debt repayment in Q1, we have paid down $250M in debt over the last two quarters, reflecting confidence in our expected ability to generate robust free cash flow on an ongoing basis. ▪ We believe our 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 efficiently and to capitalize on any additional potential market tailwinds. 8
© Mercury Systems, Inc. /Mercury Proprietary/No Tech Data/ Expectations for FY27 and beyond* ▪ Our Q1 results reflect significant progress toward consistently delivering on our target financial profile of top- line growth above our estimated market growth rate of 9.9%, adjusted EBITDA margins in the low to mid 20s, and free cash flow conversion of 50%. ▪ Based on our Q1 performance, we are raising our FY27 outlook for revenue, adjusted EBITDA, and FCF conversion. ▪ For FY27, we now expect revenue growth of double digits year-over-year, up from approaching double digits, with total revenue approaching $1.1B. • We anticipate Q2 revenue to be up 10% year-over-year, with revenue increasing through the balance of the year. ▪ We expect FY27 adjusted EBITDA margin in the high-teens and adjusted EBITDA around $210M, reflecting 40% year-over-year growth, up from our prior view of approaching $200M and 30% year-over-year growth. • We expect Q2 adjusted EBITDA margin to expand roughly 500 basis points year over year and adjusted EBITDA margin to increase quarterly through the balance of the year. ▪ Amid increased demand, we are making targeted investments in inventory, automation, and factory optimization to drive organic growth. • For the full year, we are now anticipating FY27 free cash flow conversion approaching 40%, up from approaching 35%, with positive Q2 free cash flow and second half free cash flow expected to be higher than in the first half. 9
© Mercury Systems, Inc. /Mercury Proprietary/No Tech Data/ Expectations for FY27 and beyond* - continued ▪ While our revised FY27 outlook incorporates a limited set of tailwinds that have materialized in firm bookings, it does not incorporate the benefit of potential tailwinds that could occur on a number of production programs across our portfolio, including our Common Processing Architecture, effectors, airborne applications, space, and missile defense. • Additionally, this outlook does not incorporate benefits from 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. ▪ Finally, while we are not updating today the FY28 reference points that we provided last quarter, our record Q1 performance, record backlog, and improving visibility gives us increasing confidence in our outlook beyond FY27. We expect to revisit and update these reference points as we progress through the back half of FY27. ▪ In summary, with our positive momentum coming out of a record Q1, we look forward to executing well for our customers, enabling high-performance processing and mission dominance for the warfighter at the edge, and delivering on what we believe is a significant value creation opportunity in front of us. 10 * Our previously provided FY28 reference points, along with our target profile, should not be construed as financial guidance. 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.
