Item 1.01. Entry into a Material Definitive Agreement. On February 19, 2026, Candel Therapeutics, Inc. (the “Company”) announced its entry into a purchase and sale agreement (the “Purchase Agreement”) with funds managed by RTW Investments, LP (the “Purchaser”). Under the terms of the Purchase Agreement, the Purchaser has agreed to pay the Company $100 million (the “Purchase Price”) upon the marketing approval of the Company’s product referred to as CAN-2409 (aglatimagene besadenovec) (the “Product”) for the treatment of intermediate-risk and high-risk localized prostate cancer by the U.S. Food and Drug Administration (the “FDA Approval”) in exchange for a tiered royalty on future net sales of the Product in the United States. The Purchaser will be entitled to a 4.67% royalty on the portion of annual net sales in the United States that is less than or equal to $1 billion, and a 1.33% royalty on the portion of annual net sales in the United States, exceeding $1 billion. The 4.67% tier will increase to 6.67% if annual net sales do not achieve certain specified levels (the “Ratchet”), subject to a cure opportunity by the Company (provided that such Ratchet and cure opportunity may each subsequently occur more than once). The royalty payments become payable following the first commercial sale of the Product in the United States and end upon the Purchaser’s receipt of $250 million in royalty payments (the “Royalty Cap”). If the Company undergoes a change of control (as defined in the Purchase Agreement) with, or sells the Product and all of the Product rights to, a third party, the Purchase Agreement provides the Company and the Purchaser with an option for the Company to pay certain specified amounts to terminate the Purchase Agreement, depending upon the timing for such transaction, up to the Royalty Cap (the “Buy-Out Option”). If either party exercises the Buy-Out Option, the Purchase Agreement will automatically terminate upon payment of the specified amount. The transaction is subject to certain closing conditions, including that FDA Approval must occur by a specified date, conditions related to the Company’s indebtedness and other customary closing conditions. The Purchase Agreement also contains customary representations, warranties and indemnities on the part of the Company and the Purchaser and customary covenants on the part of the Company, including around the Company’s indebtedness as well as licensing and other activities related to the Product and Product rights. The foregoing description of the Purchase Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Purchase Agreement, a copy of which will be included as an exhibit to the Company’s Annual Report on Form 10-K for the year ending December 31, 2025 to be filed with the Securities and Exchange Commission.
