Item 3.01 Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

On November 19, 2025, Liminatus Pharma, Inc. (the “Company”) received notices from the Nasdaq Listing Qualifications Department of The Nasdaq Stock Market LLC indicating that the Company was no longer in compliance with (i) Nasdaq Listing Rule 5450(b)(2)(A) due to its failure to maintain a minimum Market Value of Listed Securities (MVLS) of $50,000,000 (the “MVLS Rule”), based upon a review of the Company’s MVLS for the last 30 consecutive business days and (ii) Nasdaq Listing Rule 5450(b)(2)(C) due to its failure to maintain a minimum Market Value of Publicly Held Shares (MVPHS) of $15,000,000 (the “MVPHS Rule”), based upon a review of the Company’s MVPHS for the last 30 consecutive business days. The Nasdaq staff noted that the Company also does not meet the requirements under Listing Rule 5450(b)(3)(A), which requires the Company to have total assets and total revenue of at least $50 million each for the most recently completed fiscal year or two of the three most recently completed fiscal years.

The notification has no immediate effect on the listing of the Company’s common stock, and its common stock will continue to trade on Nasdaq under the symbol “LIMN” at this time.

Under the Nasdaq rules, the Company has been provided a compliance period of 180 calendar days, or until May 18, 2026, in which to regain compliance with the MVLS Rule. If at anytime during this compliance period the Company’s MVLS closes at $50,000,000 or more for a minimum of ten consecutive business days, Nasdaq will provide the Company written confirmation of compliance and this matter will be closed. In the event the Company does not regain compliance with the MVLS Rule prior to the expiration of the compliance period, it will receive written notification that its securities are subject to delisting. At that time, the Company may appeal the delisting determination to a Nasdaq Hearings Panel. Alternatively, the Company may consider applying for a transfer to The Nasdaq Capital Market (the “Capital Market”), provided it meets the Capital Market’s continued listing requirements.

Under the Nasdaq rules, the Company has been provided a compliance period of 180 calendar days, or until May 18, 2026, in which to regain compliance with the the MVPHS Rule. If at anytime during this compliance period the Company’s MVPHS closes at $15,000,000 or more for a minimum of ten consecutive business days, Nasdaq will provide the written confirmation of compliance and this matter will be closed. In the event the Company does not regain compliance with the MVPHS Rule prior to the expiration of the compliance period, it will receive written notification that its securities are subject to delisting. At that time, the Company may appeal the delisting determination to a Nasdaq Hearings Panel. Alternatively, the Company may consider applying to transfer the Company’s securities to the Capital Market, provided it meets the Capital Market’s continued listing requirements. 

The Company is working diligently to regain compliance with Nasdaq’s listing rules. However, there can be no assurance that the Company will be able to regain compliance within the prescribed time period.

This announcement is made in compliance with Nasdaq Listing Rule 5810(b), which requires prompt disclosure of receipt of a deficiency notification.
