Item 1.01 Entry into a Material Definitive Agreement.

On February 17, 2026, Liminatus Pharma, Inc. (the “Company”) announced the pricing of a “best efforts” public offering of (i) 8,270,000 shares of its common stock, par value $0.0001 per share (“common stock”), (ii) 5,543,000 pre-funded warrants to purchase up to 5,543,000 shares of common stock (the “Pre-Funded Warrants”) and (ii) 13,813,000 common stock purchase warrants to purchase up to 20,719,500 shares of common stock (the “Warrants”), at a combined public offering price of $0.29 per share (or $0.2899 per Pre-Funded Warrant) and Warrant (the “Offering”).

Each Pre-Funded Warrant has an exercise price of $0.0001 per share upon issuance for one share of common stock and will not expire prior to exercise. Each Warrant has an exercise price of $0.29 per share, is exercisable upon issuance for one and a half shares of common stock, and will expire five years following the date of issuance. The exercise price and number of shares of common stock issuable upon exercise is subject to appropriate adjustment in the event of stock dividends, stock splits, reorganizations or similar events affecting the common stock and the exercise price.

In connection with the Offering, on February 17, 2026, the Company entered into a securities purchase agreement (the “Purchase Agreement”) with certain purchasers party thereto. The Purchase Agreement contains customary representations, warranties and agreements of the Company and the purchasers and customary indemnification rights and obligations of the parties. Pursuant to the Purchase Agreement, the Company agreed not to issue, enter into any agreement to issue or announce the issuance or proposed issuance of any shares of common stock or any securities convertible into or exercisable or exchangeable for shares of common stock or file any registration statement or prospectus, or any amendment or supplement thereto for 180 days after the closing date of the Offering, subject to certain exceptions. The Company also agreed not to effect or enter into an agreement to effect any issuance of common stock or any securities convertible into or exercisable or exchangeable for shares of common stock involving a Variable Rate Transaction (as defined in the Purchase Agreement) until 180 days after the closing date of the Offering, subject to certain exceptions.

In connection with the Offering, on February 17, 2026, the Company entered into a placement agency agreement (the “Placement Agency Agreement”) with Maxim Group LLC, as placement agent in connection with the Offering (the “Placement Agent”). The Company paid the Placement Agent a cash fee of 8.0% of the aggregate gross proceeds raised in the Offering. The Company also agreed to reimburse the Placement Agent for all reasonable out-of-pocket costs and expenses incurred in connection with the Offering in an aggregate amount up to $100,000. In addition, the Company issued to the Placement Agent warrants (the “Placement Agent Warrants”) to purchase 690,650 shares of common stock (representing 5.0% of the number of shares of common stock sold in the Offering). The Placement Agent Warrants are immediately exercisable at an exercise price of $0.319 (or 110% of the public offering price for the shares of common stock and common warrants offered in the Offering) and will expire on the fifth anniversary of the commencement of sales of the Offering.

The Company’s directors and executive officers have agreed, subject to certain exceptions, not to offer, issue, sell, contract to sell, encumber, grant any option for the sale of or otherwise dispose of any shares of common stock or other securities convertible into or exercisable or exchangeable for common stock for a period of 180 days following the closing date of the Offering without the prior written consent of the Placement Agent, subject to certain exceptions.

The shares of common stock, the Pre-Funded Warrants, the Warrants and the Placement Agent Warrants described above and the underlying shares of common stock were offered pursuant to the Registration Statement on Form S-1 (File No. 333-293364), as amended, which was declared effective by the Securities and Exchange Commission on February 13, 2026.

The closing of the Offering occurred on February 18, 2026. The Company received net proceeds of approximately $3.46 million, after deducting the estimated offering expenses payable by the Company, including the placement agent fees. The Company intends to use the net proceeds from the offering primarily for clinical trials, research and development, sales and marketing and working capital and general corporate purposes.

The foregoing summaries of the Purchase Agreement, the Placement Agency Agreement, the Pre-Funded Warrants, the Warrants, the Placement Agent Warrant and the lock-up agreements do not purport to be complete and are subject to, and qualified in their entirety by, the forms of such documents, which are filed as exhibits 4.1, 4.2, 4.3, 10.1, 10.2 and 10.3 to this Current Report on Form 8-K, which are incorporated by reference.
