Item 1.01 Entry Into a Material Definitive Agreement

Common Stock Sales Agreement

On October 3, 2025, XOMA Royalty Corporation (the “Company”) entered into an “at the market” sales agreement (the “Common Stock Sales Agreement”) with Leerink Partners LLC (“Leerink”), pursuant to which the Company may offer and sell from time to time up to $75,000,000 of shares of the Company’s common stock, par value $0.0075 (the “Common Shares”), through Leerink, as the Company’s sales agent.

Sales of the Common Shares, if any, pursuant to the Common Stock Sales Agreement, may be made in transactions that are deemed to be an “at the market offering” as defined in Rule 415(a)(4) under the Securities Act of 1933, as amended (the “Securities Act”), including sales made directly on or through The Nasdaq Global Market (“Nasdaq”) or on any other existing trading market for the Common Shares. The Company has no obligation to sell any of the Common Shares under the Common Stock Sales Agreement, and may at any time suspend offers under the Common Stock Sales Agreement or terminate the Common Stock Sales Agreement.

Leerink will act as a sales agent and will use commercially reasonable efforts to sell on the Company’s behalf all of the Common Shares requested to be sold by the Company, consistent with their normal trading and sales practices, on mutually agreed terms between Leerink and the Company. The Company currently intends to use the net proceeds of the offering of Common Shares, if any, to acquire additional potential royalty and milestone revenue streams, for working capital and other general corporate purposes.

Under the terms of Common Stock Sales Agreement, the Company will pay Leerink a commission of up to 3.0% of the aggregate gross proceeds from each Common Share sold through it under the Common Stock Sales Agreement. In addition, the Company has also provided Leerink with customary representations, warranties and indemnification rights and has agreed to reimburse certain expenses incurred by Leerink in connection with the offering of Common Shares. The Common Stock Sales Agreement may be terminated by Leerink or the Company at any time upon notice to the other party, as set forth in the Common Stock Sales Agreement, or by Leerink at any time in certain circumstances, including the occurrence of a material and adverse change in the Company’s business or financial condition that may materially impair Leerink’s ability to sell the Common Shares.

Preferred Stock Sales Agreement

Also on October 3, 2025, the Company entered into an “at the market” sales agreement (the “Preferred Stock Sales Agreement” and together with the Common Stock Sales Agreement, the “Sales Agreements”) with H.C. Wainwright & Co., LLC (“Wainwright”), pursuant to which the Company may offer and sell from time to time up to $50,000,000 of the Company’s depositary shares (the “Depositary Shares,” and together with the Common Shares, the “Shares”), each representing 1/1000th of a share of the Company’s 8.375% Series B cumulative perpetual preferred stock, par value $0.05, through Wainwright, as the Company’s sales agent.

Sales of the Depositary Shares, if any, pursuant to the Preferred Stock Sales Agreement, may be made in transactions that are deemed to be an “at the market offering” as defined in Rule 415(a)(4) under the Securities Act, including sales made directly on or through Nasdaq or on any other existing trading market for the Depositary Shares. The Company has no obligation to sell any of the Depositary Shares under the Preferred Stock Sales Agreement, and may at any time suspend offers under the Preferred Stock Sales Agreement or terminate the Preferred Stock Sales Agreement.

Wainwright will act as a sales agent and will use commercially reasonable efforts to sell on the Company’s behalf all of the Depositary Shares requested to be sold by the Company, consistent with their normal trading and sales practices, on mutually agreed terms between Wainwright and the Company. The Company currently intends to use the net proceeds of the offering of Depositary Shares, if any, to fund future dividends and any remaining net proceeds to acquire additional potential royalty and milestone revenue streams, for working capital and other general corporate purposes.

Under the terms of the Preferred Stock Sales Agreement, the Company will pay Wainwright a commission of up to 3.0% of the aggregate gross proceeds from each Depositary Share sold through it under the Preferred Stock Sales Agreement. In addition, the Company has also provided Wainwright with customary representations, warranties and indemnification rights and has agreed to reimburse certain expenses incurred by Wainwright in

connection with the offering of Depositary Shares. The Preferred Stock Sales Agreement may be terminated by Wainwright or the Company at any time upon notice to the other party, as set forth in the Preferred Stock Sales Agreement, or by Wainwright at any time in certain circumstances, including the occurrence of a material and adverse change in the Company’s business or financial condition that may materially impair Wainwright’s ability to sell the Depositary Shares.

The offering and sale of the Shares has been registered under the Securities Act, pursuant to the Company’s Registration Statement on Form S-3 (File No. 333-277794) (the “Registration Statement”), which was originally filed with the Securities and Exchange Commission (“SEC”) on March 8, 2024 and declared effective by the SEC on June 17, 2024, the base prospectus contained within the Registration Statement, and prospectus supplements that were filed with the SEC on October 3, 2025 in connection with the offer and sale of the Shares under each applicable Sales Agreement.
