HCW Biologics Reports First Quarter 2026

Business Highlights and Financial Results

Miramar, FL – May 14, 2026 – HCW Biologics Inc. (the “Company” or “HCW Biologics”) (NASDAQ: HCWB), a clinical-stage biopharmaceutical company focused on developing transformative fusion immunotherapeutics to treat autoimmune disease, cancer and senescence-associated dysplasia, today reported financial results and recent business highlights for the three months ended March 31, 2026.

The Company remains on track to provide preliminary clinical data readout from the first two dose levels of the Phase 1 clinical study evaluating HCW9302 in alopecia areata in the first half of 2026. There are two clinical sites actively enrolling patients, and enrollment has been on schedule. HCW9302 is an injectable, first-in-kind interleukin 2 (“IL-2”) fusion protein complex designed to suppress the hair-follicle killing activities of the auto-reactive immune cells typically found in patients suffering with alopecia areata by activating and expanding regulatory T (“Treg”) cells. The Company has not reported any dose limiting toxicities in the patients treated to date. With continued patient enrollment, the full Phase 1 human data readout is expected in the fourth quarter of 2026.

Dr. Hing C. Wong, the Company’s Founder and Chief Executive Officer, stated, “HCW9302 was selected as the lead product candidate for the Company’s autoimmune program because it has demonstrated relatively high IL-2Rα affinity and sustains serum exposure, which implies it has a strong profile for the treatment of autoimmune disorders. The Company’s preclinical studies in nonhuman primates show that HCW9302 achieves significantly longer serum half-life and exhibits strong biological activity in relatively low doses, which could appear in the human data readout as support for enhanced receptor selectivity, better tolerability and reduced off-target effects.”

Business Highlights

Transaction Closed for Exclusive Worldwide License for HCW11-006

On March 16, 2026, the closing for the licensing arrangement with Beijing Trimmune Biotech Co., Ltd (“Trimmune”) occurred upon receipt of the full nonrefundable upfront license fee. The Trimmune upfront license fee consisted of $3.5 million in gross cash proceeds, or $2.9 million net of taxes, and an in-kind payment of a transferable minority equity interest in Trimmune with a fair value of $3.5 million. For the three months ended March 31, 2026, the Company recognized $6.5 million in revenue and $470,000 in deferred revenue.

Commercial-Ready

Molecules Used as Reagents

On March 13, 2026, Science Advances, a peer-reviewed, high-impact journal, released a publication with the Company’s data that showed the Company’s proprietary, commercial-ready compound, HCW9206, could fundamentally change how CAR-T cell therapies are manufactured and potential improve their clinical efficacy against diseases such as cancer and HIV. These findings support the Company’s belief that HCW9206 is a leap forward in both clinical potential and manufacturing efficiency. The Company is actively seeking a corporate partner to commercialize the reagent program.

February 2026 Equity Offering

On February 19, 2026, the Company completed a $1.5 million equity financing with an existing investor in which it issued Pre-Funded Warrants to purchase 2,477,292 shares of Common Stock for $0.0001 per share and Common Stock Warrants to purchase up to 2,477,292 shares of Common Stock for $0.6055 per share. Contemporaneously with this transaction, the Company agreed to amend previously issued Common Stock Warrants to purchase up to 3,020,410 shares of Common Stock to lower the exercise price from $2.41 per share to $0.6055 per share. The Warrants are subject to stockholder approval.

First Quarter 2026 Financial Results

Revenues: Revenues for the three months ended March 31, 2025 and 2026 were $5,065 and $6.5 million, respectively. Since inception, the Company’s revenues have been derived exclusively from its licenses. Under the Wugen License and supply agreements, the Company has recognized over $16.0 million of aggregate revenues since the inception of the license in 2020. In the three months ended March 31, 2025, Wugen was winding down its clinical programs in NK-Cell therapies to focus exclusively on its breakthrough CAR-T program that is in its pivotal clinical trial. In the three months ended March 31, 2026, the Company completed the closing of the exclusive, worldwide licensing agreement with Trimmune for the in vivo rights for HCW11-006. The nonrefundable upfront license fee consisted of $3.5 million in gross cash proceeds and $3.5 million in-kind in the form of a transferable minority equity interest in Trimmune.

Research and development (R&D) expenses: R&D expenses for the three months ended March 31, 2025 and 2026 were $1.5 million and $1.3 million, respectively, a decrease of $220,763, or 15%. The change was

HCW Biologics Reports Fourth Quarter 2025 and Fiscal Year 2025

Business Highlights and Financial Results

Miramar, FL – March 31, 2026 – HCW Biologics Inc. (the “Company” or “HCW Biologics”) (NASDAQ: HCWB), a clinical-stage biopharmaceutical company developing transformative fusion immunotherapeutics to support or treat diseases promoted by chronic inflammation, today reported financial results and recent business highlights for its three months ended December 31, 2025.

On November 17, 2025, the Company initiated its first-in-human clinical trial to evaluate HCW9302, the lead product candidate for the Company’s program to develop treatments for autoimmune disorders and proinflammatory diseases, in patients with areata alopecia. HCW9302 is a subcutaneously injectable, first-in-kind interleukin-2 (“IL-2”) fusion immunotherapeutic. IL-2, the active component of HCW9302, is the cytokine in humans and other vertebrates responsible for maintaining the proper numbers and functions of Treg cells in the body. Treg cells control excessive inflammation caused by other immune cells, which is the etiology of autoimmune diseases.

The Company believes that HCW9302 can suppress the hair-follicle killing activities of the auto-reactive immune cells by activating and expanding regulatory T cells (“Treg”) cells. There are no curative FDA approved treatments of this indication. Alopecia areata causes sudden hair loss and can have a significant negative impact on patients’ quality of life and psychological health. The National Alopecia Areata Foundation estimates approximately 160 million people worldwide and 7 million people in the United States have alopecia areata. The condition affects about 2% of the global population at some point in their lifetime.

The Phase 1 multi-center dose-escalation study of HCW9302 is designed to treat up to 30 patients. The primary objectives of the study are to evaluate the safety of HCW9302, injected under the skin (subcutaneously), and to determine the recommended dose level to advance to later phase clinical studies. A preliminary human data read out is expected in the first half of 2026.

Dr. Hing C. Wong, the Company’s Founder and Chief Executive Officer said, “We are excited to be the sponsor of this clinical study to evaluate this promising new treatment for alopecia areata. We will be conducting additional ancillary studies to provide further insights into disease responses and the effects of HCW9302 on proliferation and function of immune cells, particularly Treg cells.”

Dr. Wong continued, “Based the results of our preclinical studies including non-human primates, we believe the human data read out will show that HCW9302 has superior IL-2Rα affinity and will sustain serum exposure, which could potentially make it favorable for the expansion and in increasing the functionality of Treg for autoimmune disease treatments. HCW9302 was well tolerated in non-human primate studies. If this remains the case in human studies, this would be a significant improvement over conventional IL-2 therapies that have low tolerability profiles. We believe the data will confirm that HCW9302 can achieve strong biological activity at lower therapeutic dose levels, and as a result, will have a favorable tolerability and at the same time can potentially enhance receptor selectivity and reduce off-target effects.”
