Entry into a Material Definitive Agreement.

On August 11, 2026, NuScale Power Corporation (the “Company”) entered into a Sales Agreement (the “Sales Agreement”) with UBS Securities LLC (“UBS”), B. Riley Securities, Inc. (“B. Riley”), Canaccord Genuity LLC (“Canaccord”), Craig-Hallum Capital Group, LLC (“Craig-Hallum”), TCBI Securities, Inc., doing business as Texas Capital Securities (“TCS”) and Tuohy Brothers Investment Research, Inc. (“Tuohy Brothers”) with respect to an at-the-market offering program under which the Company may offer and sell, from time to time at its sole discretion, shares of its Class A common stock, par value $0.0001 per share (the “Common Stock”), having an aggregate offering price of up to $750,000,000 (the “Shares”) through any of UBS, B. Riley, Canaccord, Craig-Hallum, TCS or Tuohy Brothers as its “sales agent” (together, the “Sales Agents”).

Under the Sales Agreement, the Company will set the parameters for the sale of Shares, including the number of Shares to be issued, the time period during which sales are requested to be made, limitations on the number of Shares that may be sold in any one trading day and any minimum price below which sales may not be made. Subject to the terms of the Sales Agreement, the sales agent may sell the Shares by any method that is deemed to be an “at the market offering” as defined in Rule 415(a)(4) promulgated under the Securities Act of 1933, as amended (the “Securities Act”), including sales made through The New York Stock Exchange or any other trading market for the Common Stock.

The Company will pay the sales agent a commission equal up to 2% of the gross sales proceeds of any Shares sold through the sales agent under the Sales Agreement, and has provided each sales agent with customary indemnification and contribution rights.

The Sales Agreement will terminate upon the earlier of (i) the sale of all Shares subject to the Sales Agreement or (ii) termination of the Sales Agreement in accordance with the terms and conditions set forth therein.

Any Shares to be offered and sold under the Sales Agreement will be issued and sold pursuant to the Company’s Registration Statement on Form S-3ASR (File No. 333-289467), which was filed with the Securities and Exchange Commission (“SEC”) on August 11, 2025 and became automatically effective upon filing pursuant to Rule 462(e) under the Securities Act. The Company filed a prospectus supplement, dated August 11, 2026, with the SEC in connection with the offer and sale of the Shares pursuant to the Sales Agreement.
