Item 8.01 Other Events.

On September 8, 2025, Shimmick Corporation (the “Company”) entered into an At The Market Offering Agreement (the “Sales Agreement”) with Roth Capital Partners, LLC (the “Sales Agent”). Pursuant to the Sales Agreement, the Sales Agent will act as the Company’s agent with respect to an offering and sale, at any time and from time to time, of the Company’s common stock, par value $0.01 per share (the “Shares”). The Company has authorized the sale, at its discretion, of Shares in an aggregate offering amount up to $7,800,000 under the Sales Agreement. Sales of the Shares, if any, will be made in “at the market offerings” as defined in Rule 415 under the Securities Act of 1933, as amended (the “Securities Act”).

The Shares will be sold and issued pursuant to the Company’s Registration Statement on Form S-3 which was filed on July 3, 2025 with, and declared effective on July 10, 2025 by, the U.S. Securities and Exchange Commission (the “SEC”) (File No. 333-288513, the “Registration Statement”), and a related prospectus, as supplemented by a prospectus supplement related to the Company’s “at the market offering.” Concurrently herewith, we are filing a prospectus supplement (the “Prospectus Supplement”), dated September 8, 2025, with the SEC in connection with the offer and sale of the Shares. We are not obligated to make any sales of Shares under the Sales Agreement, and no assurance can be given that we will sell any Shares under the Sales Agreement, or, if we do, as to the price or amount of Shares that we will sell, or the dates on which any such sales will take place.

The Company or the Sales Agent, under certain circumstances and upon notice to the other, may suspend the offering of the Shares under the Sales Agreement. The offering of the Shares pursuant to the Sales Agreement will terminate upon the sale of Shares in an aggregate offering amount equal to $7,800,000, or sooner if either the Company or the Sales Agent terminates the Sales Agreement.

The Company will pay the Sales Agent a cash commission in an amount up to 3% of the gross proceeds from each sale of Shares sold pursuant to the Sales Agreement and will reimburse the Sales Agent for the documented fees and costs of its legal counsel reasonably incurred in connection with entering into the transactions contemplated by the Sales Agreement in an amount not to exceed $50,000 in the aggregate.

The Company made certain customary representations, warranties and covenants in the Sales Agreement concerning the Company and its subsidiaries and the Registration Statement, prospectus, Prospectus Supplement and other documents and filings relating to the offering of the Shares. In addition, the Company has agreed to indemnify the Sales Agent against certain liabilities, including liabilities under the Securities Act.

The foregoing description of the Sales Agreement is qualified in its entirety by reference to the Sales Agreement, a copy of which is filed as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated herein by reference.

The Shares to be sold under the Sales Agreement, if any, will be issued and sold pursuant to the Company’s Registration Statement, and its Prospectus Supplement related thereto.

This Current Report on Form 8-K shall not constitute an offer to sell or the solicitation of an offer to buy any Shares nor shall there be any sale of shares in any state or jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state or other jurisdiction.
