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

On July 24, 2026, Curis, Inc. (the “Company”) received written notice from the Nasdaq Stock Market LLC (“Nasdaq”) indicating that the Company has regained compliance with Nasdaq Listing Rule 5550(a)(2) (the “Bid Price Rule”) and is in full compliance with the terms set forth by the Nasdaq Hearings Panel (the “Panel”).

Pursuant to Listing Rule 5815(d)(4)(A), the Company will be subject to a Discretionary Panel Monitor for a one-year period from July 24, 2026. If the Company fails to maintain compliance with any continued listing requirement, the Staff will issue a Delist Determination Letter, and the Company promptly schedule a new hearing with the initial Panel or a newly convened Hearings Panel if the initial Panel is unavailable. The hearing may be oral or written, at the Company’s election. Notwithstanding Rule 5810(c)(2), the Company will not be permitted to provide Staff with a plan of compliance with respect to any deficiency that arises during the monitor period, and Staff will not be permitted to grant additional time for the Company to regain compliance with respect to any deficiency. The Hearings Panel will consider the Company’s compliance history when rendering its decision. However, there can be no assurance that such appeal will be successful or that the Company will remain listed on Nasdaq.

In addition, any forward-looking statements represent the views of the Company only as of the date of the Current Report on Form 8-K and should not be relied upon as representing the Company’s views as of any subsequent date. The Company disclaims any intention or obligation to update these forward-looking statements in the future to reflect events, information, or circumstances after the date hereof, except as may be required by law.
