| Issuer:                                     |     | HCW Biologics Inc.                                                                                                                                                                                                                                        |
| Securities Offered by Us:                   |     | Up to [●] Units, consisting of one share of our Common Stock and one Common Stock Warrant to purchase one share of Common Stock.                                                                                                                          |
|                                             |     | We are also offering to investors in Units that would otherwise result in the investor’s beneficial ownership exceeding 4.99% of our outstanding Common Stock immediately following the consummation of this offering the                                 
 opportunity to invest in Units consisting of one Pre-Funded Warrant to purchase one share of Common Stock in lieu of one share of Common Stock. For each Unit that includes a Pre-Funded Warrant purchased (without regard to any limitation on exercise  
 set forth therein), the number of Units including a share of Common Stock we are offering will be decreased on a one-for-one basis. Subject to limited exceptions, a holder of Pre-Funded Warrants will not have the right to exercise any portion of its 
 Pre-Funded Warrant if the holder, together with its affiliates, would beneficially own in excess of 4.99% (or, at the election of the holder, such limit may be increased to up to 9.99%) of the Common Stock outstanding immediately after giving effect 
 to such exercise. Each Pre-Funded Warrant will be exercisable for one share of Common Stock. The purchase price of each Unit including a Pre-Funded Warrant (and accompanying Common Stock Warrant) will be equal to the price per Unit including one     
 share of Common Stock, minus $0.0001, and the exercise price of each Pre-Funded Warrant will equal $0.0001
