## Item 3.01 Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.
As previously disclosed, on August 19, 2025, HCW Biologics Inc. (the "Company") received written notice from the Listing Qualifications Staff (the "Staff") of the Nasdaq Stock Market LLC ("Nasdaq") that as of June 30, 2025, the Company was non-compliant with Listing Rule 5550(b)(1), the "Equity Rule" for continued listing on The Nasdaq Capital Market (the "Exchange"). The Company made a timely request for a hearing before the Nasdaq Hearings Panel (the "Panel") and was granted a hearing, which was held on September 25, 2025.

On October 13, 2025, the Panel granted the Company an extension in which to regain compliance with all continued listing rules of the Exchange. The Panel's determination follows the Company's hearing on September 25, 2025, at which the Company presented, and the Panel considered, the Company's plan to regain compliance with the Equity Rule. The Panel granted the Company's request for continued listing on the Exchange, subject to, among other things, the Company demonstrating compliance with the Equity Rule by December 31, 2025, and with all other Exchange continued listing rules by February 16, 2026. The Company was advised that February 16, 2026, represents the full extent of the Panel's discretion to grant continued listing while the Company is non-compliant with the Nasdaq Listing Rules.

The Panel also required that the Company provide prompt notification of any significant events that occur during the exception period that may affect the Company's compliance with Nasdaq requirements. In addition, the Company must timely file Form 10-Q for the third quarter, and provide notice of the status of certain elements of the Company's compliance plan. Any compliance documentation submitted by the Company will be subject to review by the Panel, which may, in its discretion, request additional information before determining that the Company has complied with the terms of the exception. The Panel has discretion to review its decision to grant an exception period within 45 calendar days after issuance of the written decision.
