Amendment to Amended and Restated By-laws

On March 13, 2025, our board of directors approved an amendment (the “Certificate of Amendment”) to our amended and restated by-laws (the “By-laws”), effective as of March 13, 2025. The Certificate of Amendment amends Section 5 of Article I of the By-laws, dealing with a quorum at meetings of stockholders, to generally provide that a quorum is at least one-third of the voting power of the stock issued and outstanding and entitled to vote, present in person, or represented by proxy. Prior to effectiveness of the Certificate of Amendment, a quorum was a majority of the voting power of the stock issued and outstanding and entitled to vote, present in person, or represented by proxy. The foregoing description of the Certificate of Amendment does not purport to be complete and is qualified in its entirety by reference to the full text of the Certificate of Amendment, a copy of which is filed as Exhibit 3.5 to this Annual Report on Form 10-K and incorporated herein by reference.
