Item 2.02. Results of Operations and Financial Condition.
On August 11, 2025, Mercury Systems, Inc. (the "Company" or "we") issued a press release and an earnings presentation regarding its financial results for the fourth quarter and fiscal year ended June 27, 2025. The press release and earnings presentation are attached as exhibits 99.1 and 99.2 to this Current Report on Form 8-K and incorporated by reference herein.
Information in Item 2.02 of this Current Report on Form 8-K and the exhibits 99.1 and 99.2 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
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 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.
