We are providing the folloing disclosure in lieu of filing a Current Report on Form 8-K under Items 1.01 and 1.02.

On May 6, 2026, Redwire Corporation (the “Company”), entered into an Equity Distribution Agreement (the “2026 ATM Agreement”) by and between the Company, Truist Securities, Inc., J.P. Morgan Securities LLC, BofA Securities, Inc., TCBI Securities, Inc., doing business as Texas Capital Securities, A.G.P./Alliance Global Partners, B. Riley Securities, Inc., Canaccord Genuity LLC, H.C. Wainwright & Co., LLC and Roth Capital Partners, LLC (each an “Agent” and collectively, the “Agents”). Pursuant to the terms of the 2026 ATM Agreement, the Company may sell, from time to time through or to the Agents, as the Company’s sales agent and/or as principal, shares of its common stock, par value $0.0001 per share (the “Shares”), having an aggregate gross sales price of up to $350 million. The sales, if any, of the Shares made under the 2026 ATM Agreement may be made in sales deemed to be “at-the-market offerings” as defined in Rule 415 under the Securities Act of 1933, as amended (the “Securities Act”), including sales made directly on the New York Stock Exchange, on any other existing trading market for the Shares, or to or through a market maker other than on an exchange. The Agents may also sell the Shares by any other method permitted by law, including in block trades and privately negotiated transactions. The Agents will use commercially reasonable efforts consistent with their normal trading and sales practices and applicable laws and regulations to sell the Shares from time to time, based upon the Company’s instructions (including any price or size limits the Company imposes). The Company intends to use the net proceeds from the offering, after deducting the Agents’ commissions and the Company’s offering expenses, for working capital purposes and other general corporate purposes, which may include financing of capital expenditures, repayment or refinancing of outstanding debt, financing acquisitions or investments, financing other business opportunities, and general working capital purposes.

For sales of Shares through the Agents, the Company will pay the Agents a commission of up to 3% of the gross sales price per Share. The Company may also sell Shares to the Agents as principal for the Agents’ own account at a price agreed upon at the time of sale. If the Company sells Shares to the Agents as principal, the Company will enter into a separate terms agreement with the Agents. The Company has no obligation to sell any Shares under the 2026 ATM Agreement, and may at any time suspend the offering of Shares under the 2026 ATM Agreement. Unless earlier terminated as provided below, the 2026 ATM Agreement will automatically terminate upon the issuance and sale of all of the Shares subject to the 2026 ATM Agreement. The Company and each Agent, solely with respect to its own obligations, may terminate the 2026 ATM Agreement at any time by written notice.

The 2026 ATM Agreement contains customary representations and warranties of the parties and indemnification and contribution provisions under which the Company and the Agents have agreed to indemnify each other against certain liabilities, including liabilities under the Securities Act.

The Shares will be offered and sold pursuant to a shelf registration statement on Form S-3ASR (File No. 333-289380), which was filed with the Securities and Exchange Commission on August 7, 2025 and became effective upon filing, and a related prospectus supplement, dated May 6, 2026.

In connection with the Company’s entry into the 2026 ATM Agreement, on May 6, 2026, the Company terminated its Equity Distribution Agreement (the “ATM Agreement”), dated November 10, 2025, by and between the Company, Truist Securities, Inc., J.P. Morgan Securities LLC, BofA Securities, Inc. and TCBI Securities, Inc. doing business as Texas Capital Securities.
