## Item 3.01 Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.
On February 26, 2026, the HCW Biologics Inc. (the "Company") received written notice form the Listing Qualifications Staff (the "Staff") of the Nasdaq Capital Market Nasdaq Stock Market LLC ("Nasdaq") that the Nasdaq Hearings Panel (the "Panel") found that the Company regained compliance with all continued listing rules of the Nasdaq Capital Market (the "Exchange"), according to the terms of the Panel's decision letter dated October 13, 2025.

On October 13, 2025, the Panel had granted the Company an extension in which to regain compliance with all continued listing rules of the Exchange, subject to, among other things, the Company demonstrating compliance with Listing Rule 5550(b)(1), the "Equity Rule," by December 31, 2025, and with all other Exchange continued listing rules by February 16, 2026.

In accordance with the partial compliance letter dated January 7, 2026, the Company remains subject to the Mandatory Panel Monitor for a period of one year from the date of this letter. If, within that one-year monitoring period, the Staff finds the Company again out of compliance with the Equity Rule that was the subject of the exception, notwithstanding Rule 5810(c)(2), the Company will not be permitted to provide the Staff with a plan of compliance with respect to that deficiency and the Staff will not be permitted to grant additional time for the Company to regain compliance with respect to that deficiency, nor will the Company be afforded an applicable cure or compliance period pursuant to Rule 5810(c)(3). Instead, the Staff will issue a Delist Determination Letter and the Company will have an opportunity to request a new hearing with the initial Panel or a newly convened Hearings Panel if the initial Panel is unavailable. The Company will have the opportunity to respond/present to the Hearings Panel as provided by Listing Rule 5815(d)(4)(C). The Company's securities may be at that time delisted from Nasdaq.

**HCW Biologics Regains Compliance with All Continued Listing Rules for Nasdaq**

**Per Nasdaq Determination Letter**

**Miramar, FL** – March 2, 2026 – HCW Biologics Inc. (the "Company" or "HCW Biologics") (Nasdaq: HCWB), a clinical-stage biopharmaceutical company focused on discovering and developing novel immunotherapies to lengthen healthspan by disrupting the link between inflammation and disease, today reported that, on February 26, 2026, the Nasdaq Hearings Panel (the "Panel") of The Nasdaq Stock Market LLC ("Nasdaq" or the "Exchange") found that the Company regained compliance with all continued listing rules of The Nasdaq Capital Market.

Dr. Hing C. Wong, the Company's Founder and CEO, stated "We appreciate the discretion of the Nasdaq Panel to provide us with the time we needed to regain compliance with the Equity Rule. Regaining compliance allows us to continue to access the public markets for capital we need to advance our first-in-class immunotherapeutic drugs that we believe will transform the way we treat autoimmune diseases, cancer and other senescence-associated diseases."

**About HCW Biologics:**

HCW Biologics Inc. (NASDAQ: HCWB) is a clinical-stage biopharmaceutical company developing proprietary immunotherapies to treat diseases promoted by chronic inflammation, especially age-related and senescence-associated diseases. The Company's immunotherapeutics represent a new class of drug that it believes have the potential to fundamentally change the treatment of cancer and many other diseases and conditions that are promoted by chronic inflammation — and in doing so, improve patients' quality of life and possibly extend longevity. Chronic inflammation, including inflammaging, is believed to be a significant contributing factor to the cause for senescence-associated diseases and conditions that diminish healthspan, including many types of cancer, autoimmune diseases, and neurodegenerative diseases, as well as indications that impact quality-of-life that are not life-threatening. The Company lead product candidate for its autoimmune program is HCW9302, subcutaneously injectable, first-in-kind interleukin-2 ("IL-2") fusion molecule with a tissue-factor scaffold that was constructed using the Company's TOBI™ platform technology. HCW9302 is currently being evaluated in a Phase 1 clinical study in patients with alopecia areata, which initiated in November 2025 (NCT07049328). The

------

Company has identified two preclinical lead product candidates for internal development constructed with its proprietary TRBC drug discovery and development platform, constructed with a protein-based scaffold. HCW11-018b ("Big BiTE") is a tetra-valent T-cell engager designed to address shortfalls of bi-specific T-cell engagers (BiTE) related to manufacturability, safety profile, and ability to treat a wide spectrum of solid tumors. HCW11-040 is a pembrolizumab-based, tetra-valent immune checkpoint inhibitor. To improve efficacy, HCW11-040 is equipped with other moieties in addition to pembrolizumab which neutralizes the immunosuppressive cytokine, TGF-β, and activates effector immune cell responses. A key aspect of the Company's clinical development and financing strategy is to focus on its business development programs. To date, the Company has entered two licensing agreements in which it has licensed exclusive, worldwide rights for some of its proprietary molecules.
