**Item 3.03 Material Modification to Rights of Security Holders.**

On June 15, 2026, at the Annual Meeting of Stockholders of HCW Biologics Inc., a Delaware corporation (the "Company"), the stockholders granted to the Board of Directors of the Company the authority to effectuate a reverse split of the Company's issued and outstanding shares of common stock, par value $0.0001 per share (the "Common Stock"). On June 24, 2026, the Board of Directors (the "Board") approved a reverse stock split at a ratio of 1 - for - 6 (one for six) shares (the "Reverse Stock Split"). The Company expects that the effective time of the Reverse Stock Split will be at or about 12:01 a.m. Eastern time on Tuesday, June 30, 2026 (the "Effective Date"), with the Common Stock trading on The Nasdaq Capital Market ("Nasdaq") on a reverse split-adjusted basis under the Company's existing trading symbol, "HCWB," at the market open on Tuesday, June 30, 2026.

***Reasons for Reverse Stock Split***

As of June 24, 2026, the Company's shares traded over $1.00 per share for 27 consecutive trading days; however, the trading price was sustained at the minimum level. According to the terms contained in a decision letter from the Nasdaq Hearings Panel (the "Panel") delivered on May 29, 2026, any future noncompliance of the Common Stock with Nasdaq Listing Rule 5550(a), or (the "Bid Price Rule") prior to September 22, 2026, will result in automatic delisting of the Common Stock. The Company is effecting the Reverse Stock Split now in an effort to ensure the Company remains compliant with the Bid Price Rule as well as the terms required by the Panel.

***Effects of the Reverse Stock Split***

*Effective Date; Symbol; CUSIP Number.* The Reverse Stock Split will become effective with Nasdaq, and the Common Stock will begin trading on a reverse split-adjusted basis, at the open of business on the Effective Date. In connection with the Reverse Stock Split, the CUSIP number for the Common Stock will change to 40423R303.

*Split Adjustment; Treatment of Fractional Shares*. On the Effective Date, the total number of shares of Common Stock held by each stockholder of the Company will be converted automatically into the number of shares of Common Stock equal to: (i) the number of issued and outstanding shares of Common Stock held by each such stockholder immediately prior to the Reverse Stock Split divided by (ii) six (6). Any fractional share of Common Stock that would otherwise result from the Reverse Stock Split will be rounded up to the next whole share and, as such, any stockholder who otherwise would have held a fractional share after giving effect to the Reverse Stock Split will instead hold one whole share of the post-Reverse Stock Split Common Stock after giving effect to the Reverse Stock Split. As a result, no fractional shares will be issued in connection with the Reverse Stock Split and no cash, scrip, or other consideration will be paid in connection with any fractional shares that would otherwise have resulted from the Reverse Stock Split. The Company intends to treat stockholders holding shares of Common Stock in "street name" (that is, held through a bank, broker, or other nominee) in the same manner as stockholders of record whose shares of Common Stock are registered in their names. Banks, brokers, or other nominees will be instructed to effect the Reverse Stock Split for their beneficial holders holding shares of the Company's Common Stock in "street name"; however, these banks, brokers, or other nominees may apply their own specific procedures for processing the Reverse Stock Split.

Also, on the Effective Date, all options and warrants of the Company outstanding immediately prior to the Reverse Stock Split will be adjusted by (i) dividing the number of shares of Common Stock into which the options and warrants are exercisable or convertible by six (6) and (ii) multiplying the exercise or conversion price thereof by six (6), all in accordance with the terms of the plans, agreements, or arrangements governing such options and warrants and subject to rounding up to the nearest whole share.

*Non-Certificated Shares*. Those Company stockholders who hold their shares in electronic form do not need to take any action, as the effect of the Reverse Stock Split will automatically be reflected in their accounts with the Company's transfer agent. Those stockholders who hold their shares in "street name" will receive instructions from their bank, broker, or nominee.

*Amended Certificate of Incorporation.* The Company effected the Reverse Stock Split pursuant to the Company's filing of a Certificate of Amendment of Certification of Incorporation with the Secretary of State of the State of Delaware on June 24, 2026 to advance the first day of trading on a reverse split-adjusted basis to the Effective Date, all in accordance with the Delaware General Corporation Law. The Certificate of Amendment of Certificate of Incorporation is expected to become effective at or about 12:01 a.m. Eastern time on the Effective Date. A copy of the Certificate of Amendment of Certificate of Incorporation is attached as Exhibit 3.1 to this Current Report.

*Stockholder Approval.* As disclosed above and as reported on Form 8-K filed on June 15, 2026, the Company's stockholders approved an amendment to the Company's Certificate of Incorporation to implement one or more reverse stock splits of the outstanding shares of the Common Stock (as necessary to maintain a listing of the Common Stock on Nasdaq in an aggregate range from one-for-five (1:5) up to one-for-twenty (1:20), or anywhere between, all as determined in the sole discretion of the Company's Board of Directors. The stockholder approval occurred at the Annual Meeting of Stockholders held on June 15, 2026 at 10 a.m. Eastern time.

*Capitalization*. Prior to the Reverse Stock Split, the Company was authorized to issue 250,000,000 shares of Common Stock. There will be no change in the number of authorized shares as a result of the Reverse Stock Split. As of June 25, 2026, there were 9,581,079 shares of Common Stock outstanding. As a result of the Reverse Stock Split, there will be approximately 1,596,849 shares of Common Stock outstanding (subject to adjustment due to the effect of rounding fractional shares into whole shares). The number of shares of preferred stock that the Company is authorized to issue will not be impacted; none is currently issued and outstanding.

Immediately after the Reverse Stock Split, each stockholder's relative ownership interest in the Company and proportional voting power will remain virtually unchanged except for minor changes and adjustments that will result from rounding fractional shares of Common Stock into whole shares.

## Exhibit 99.1

**Exhibit 99.1**

![](ex99-1_001.jpg)

**HCW Biologics Announces 1-for-6 Reverse Stock Split**

**Effective on June 30, 2026**

*Company completed 28 consecutive trading days above $1.00 per share on June 25, 2026*

 

*Reverse stock split effectuated to ensure ongoing compliance with the Bid Price Rule and additional requirements from Nasdaq Hearings Panel* 

**Miramar, FL** – June 26, 2026 – HCW Biologics Inc. (the "Company" or "HCW Biologics") (NASDAQ: HCWB), a U.S.-based clinical-stage biopharmaceutical company developing transformative fusion immunotherapeutics to support or treat diseases promoted by chronic inflammation, focusing on autoimmune disorders and other inflammatory diseases, cancer and senescence-associated dysplasia, today announced that its Board of Directors has approved a 1-for-6 reverse stock split of the Company's common stock, par value $0.0001 ("Common Stock"), which will be effective at 12:01 a.m. Eastern Time on June 30, 2026. The Company's Common Stock will be traded on The Nasdaq Capital Market on a reverse split-adjusted basis beginning on June 30, 2026, under the Company's existing trading symbol "HCWB."

After an appeal, the Company received a decision letter from a Nasdaq Hearings Panel (the "Panel") on May 29, 2026, which provided a path to compliance with Nasdaq Listing Rule 5550(a) (the "Bid Price Rule"). The primary requirement in the Panel's decision letter was that the Company's Common Stock must trade above $1.00 per share for a period of 20 days prior to July 29, 2026. The Company's Common Stock completed 20 trading days above $1.00 per share as of June 12, 2026, and has continued to trade around $1 per share since that time. Given the Panel's stated requirements, including that the Company maintain compliance with the Bid Price Rule or face immediate delisting, the reverse stock split is intended to ensure compliance with the Bid Price Rule as well as other conditions required by the Panel. The new CUSIP number following the reverse stock split will be 40423R303. The Company filed the relevant amendments to its Certificate of Incorporation with the Delaware Secretary of State on June 24, 2026 to effect the reverse split on June 30, 2026.

The reverse stock split will affect all stockholders uniformly and will not alter any stockholder's percentage ownership interest in the Company, except to the extent that the reverse stock split would otherwise result in any of the Company's stockholders owning a fractional share as described in more detail below.

The reverse stock split will reduce the number of shares of Common Stock issued and outstanding from 9,581,079 (the number of issued and outstanding shares as of June 25, 2026) to approximately 1,596,849. The total authorized number of shares of Common Stock will remain at 250,000,000 shares of Common Stock and the per-share par value will remain at $0.0001 per share. No fractional shares will be issued in connection with the reverse stock split. Each stockholder who would otherwise be entitled to receive a fraction of a share of the Company's Common Stock will instead receive one whole share of Common Stock in connection with the reverse stock split.

As of the effective date of the reverse stock split, the number of shares of Common Stock available for issuance under the Company's equity incentive plans and issuable upon the exercise of stock options and warrants outstanding immediately prior to the reverse stock split will be proportionately affected by the reverse stock split. The exercise prices of the Company's outstanding options and warrants will be adjusted in accordance with their respective terms.

Equiniti Trust Company LLC ("Equiniti"), the Company's transfer agent, will act as the exchange agent for the reverse stock split. Those Company stockholders who hold their shares in electronic form do not need to take any action, as the effect of the Reverse Stock Split will automatically be reflected in their accounts with Equiniti. Those stockholders who hold their shares in "street name" will receive instructions from their bank, broker, or nominee.
