Item 1.01 Entry into a Material Definitive Agreement.

On June 3, 2026, Aeva Technologies, Inc., a Delaware corporation (the “Company”), entered into an Underwriting Agreement (the “Underwriting Agreement”) with Morgan Stanley & Co. LLC, acting as representative of the underwriters named in the Underwriting Agreement (the “Underwriters”), relating to the offer and sale of 4,494,382 shares of the Company’s common stock, par value $0.0001 per share (“Common Stock”), at a price to the public of $22.25 per share (the “Offering”). Under the terms of the Underwriting Agreement, the Company has granted the Underwriters an option, exercisable for 30 days, to purchase up to an additional 674,157 shares at the public offering price.

The Company expects to receive net proceeds from the Offering of approximately $94.4 million, or approximately $108.7 million if the Underwriters exercise in full their option to purchase additional shares, after deducting underwriting discounts and commissions and estimated transaction expenses. The Offering is expected to close on June 5, 2026, subject to the satisfaction of customary closing conditions.

The Offering was made pursuant to the Company’s shelf registration statement on Form S-3, filed with the Securities and Exchange Commission (“SEC”) on June 3, 2026, which became automatically effective upon filing (File No. 333-296469) and the base prospectus included therein (the “Registration Statement”), a preliminary prospectus supplement, dated June 3, 2026, filed with the SEC pursuant to Rule 424(b) under the Securities Act of 1933, as amended (the “Securities Act”), and a final prospectus supplement, dated June 3, 2026, filed with the SEC pursuant to Rule 424(b) under the Securities Act.

The Underwriting Agreement contains customary representations, warranties and agreements by the Company, customary conditions to closing, indemnification obligations of the Company and the Underwriters, including for liabilities under the Securities Act, other obligations of the parties and termination provisions. The representations, warranties and covenants contained in the Underwriting Agreement were made only for purposes of such agreement and as of specific dates and were solely for the benefit of the parties to such agreement. The foregoing description of the Underwriting Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Underwriting Agreement. A copy of the Underwriting Agreement is attached as Exhibit 1.1 hereto and is incorporated by reference herein.
