 LLC, you are considered the stockholder of record with respect to those shares, and these proxy materials were sent directly to you by HCW Biologics. Beneficial Owner of Shares Held in Street Name: Shares Registered in the Name of a Broker or Nominee If your shares are held in an account at a brokerage firm, bank, broker-dealer, or other similar organization, then you are the “beneficial owner” of shares held in “street name,” and these proxy materials were forwarded to you by that organization rather than from us. The organization holding your account is considered the stockholder of record for purposes of voting at the Special Meeting. As a beneficial owner, you have the right to instruct that organization on how to vote the shares held in your account. Because you are not the stockholder of record, you may not vote your shares at the Special Meeting unless you request and obtain a valid proxy from the organization that holds your shares giving you the right to vote the shares at the Special Meeting. Beneficial owners must obtain a valid proxy from the organization that holds their shares and present it to Equiniti Trust Company, LLC, at least two (2) weeks in advance of the Special Meeting.
