Item 1.01    Entry Into a Material Definitive Agreement
On November 4, 2025, Mercury Systems, Inc. (the “Company”), as the borrower, and Mercury Mission Systems, LLC, as a guarantor, entered into Amendment No. 7 (“Amendment No. 7”) to the Company’s Credit Agreement dated May 2, 2016 (the Credit Agreement, as amended, supplemented, waived, or modified from time to time through and including Amendment No. 6, the “Existing Credit Agreement”, and as amended by Amendment No. 7, the “Amended Credit Agreement”) with a syndicate of commercial banks and Wells Fargo Bank, National Association, acting on and after Amendment No. 7 as the successor administrative agent to Bank of America, N.A. Amendment No. 7 provides for (1) a new five-year revolving credit facility maturing on November 4, 2030 with $850.0 million in commitments; (2) the paydown of extensions of credit, and termination of commitments, under the Company’s existing $900.0 million revolving credit facility; (3) an increase in the amount of unrestricted cash netted from calculations of the consolidated total net leverage ratio from $150.0 million to $225.0 million (also applicable to the new springing senior secured net leverage ratio test described below); (4) an update to the definition of consolidated EBITDA related to certain non-cash charges; (5) the addition to the financial covenants of a springing quarterly maximum senior secured net leverage ratio test triggered upon the issuance of at least $350.0 million of convertible or senior unsecured debt (the “New Financial Covenant Trigger”); and (6) the removal of credit spread adjustments in interest rate calculations. The Company had $591.5 million in outstanding borrowings both prior to and following the closing of Amendment No. 7. Below is a summary of the Amended Credit Agreement.
Borrowing Capacity
The new revolving credit facility under the Amended Credit Agreement has a borrowing capacity of $850.0 million. The existing revolving credit facility under the Existing Credit Agreement was refinanced and commitments thereunder terminated on November 4, 2025 in connection with entry into the new revolving credit facility.
Maturity
The new revolving credit facility under the Amended Credit Agreement will mature on November 4, 2030.
Interest Rates and Fees
Borrowings applicable to the new revolving credit facility under the Amended Credit Agreement bear interest, at the Company’s option, at floating rates tied to SOFR or the prime rate plus an applicable percentage in the case of dollar denominated loans or, in the case of certain other currencies, such alternative floating rates as agreed. The interest rate applicable to outstanding loans is established pursuant to a pricing grid based on the Company’s total net leverage ratio.
In addition to interest on the aggregate outstanding principal amounts of any borrowings, the Company also pays a quarterly commitment fee on the unutilized commitments under the new revolving credit facility, which fee is established pursuant to a pricing grid based on the Company’s total net leverage ratio. The Company also pays customary letter of credit and agency fees.
Permitted Receivables Factoring
The Amended Credit Agreement permits up to $100.0 million in receivables factoring transactions, subject to no default or event of default at the time such factoring transaction is closed.
Covenants and Events of Default
The Amended Credit Agreement provides for customary negative covenants, including, among other things and subject to certain significant exceptions, restrictions on the incurrence of debt or guarantees, the creation of liens, the making of certain investments, loans and acquisitions, mergers and dissolutions, the sale of assets including capital stock of subsidiaries, the payment of dividends, the repayment or amending of junior debt, altering the business conducted, engaging in transactions with affiliates and entering into agreements limiting subsidiary dividends and distributions. The Amended Credit Agreement also requires the Company to comply with certain financial covenants, including a quarterly minimum consolidated cash interest charge ratio test, a quarterly maximum consolidated total net leverage ratio test, and upon the New Financial Covenant Trigger, a quarterly maximum senior secured net leverage ratio test.
The Amended Credit Agreement also provides for customary representations and warranties, affirmative covenants and events of default (including, among others, the failure to make required payments of principal and interest, certain insolvency events, and an event of default upon a change of control). If an event of default occurs, the lenders under the Amended Credit Agreement will be entitled to take various actions, including the termination of unutilized commitments, the acceleration of amounts outstanding under the Amended Credit Agreement, and all actions permitted to be taken by a secured creditor.
Guarantees and Security
The Company’s obligations under the Amended Credit Agreement are required to be guaranteed by certain of the Company’s material domestic wholly-owned restricted subsidiaries (the “Guarantors”). The obligations of both the Company and the Guarantors are secured by a perfected security interest in substantially all of the assets of the Company and the Guarantors, in each case, now owned or later acquired, including a pledge of all of the capital stock of substantially all of the Company’s domestic wholly-owned restricted subsidiaries and 65% of the capital stock of certain of its foreign restricted



subsidiaries, subject in each case to the exclusion of certain assets and additional exceptions. As of November 4, 2025, the only such Guarantor is Mercury Mission Systems, LLC.
The foregoing description of the Amended Credit Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Amendment No. 7, which is filed as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated by reference into this Item 1.01.
Item 2.02.    Results of Operations and Financial Condition.
On November 4, 2025, Mercury Systems, Inc. (the "Company") issued a press release and an earnings presentation regarding its financial results for the first quarter ended September 26, 2025. The Company’s 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.
Item 2.03 Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant
Reference is made to Item 1.01 of this Current Report on Form 8-K for a summary of the Amended Credit Agreement.
Item 8.01 Other Events
On November 3, 2025, the Company’s Board of Directors authorized a share repurchase program for the purchase of up to $200.0 million of the Company’s outstanding common stock. The program has no expiration date and repurchases may be made through open market or privately negotiated transactions from time to time at prevailing market prices. The timing and amount of repurchases will depend on market conditions and other factors.
