The Certificate of Amendment was effective as of September 19, 2022. The Company’s board of directors also has adopted amended and restated By-Laws of the Company (“Amended By-Laws”) reflecting the name change, effective on September 19, 2022. In addition, on September 16, 2022, the Company filed with the Secretary of State of the State of Delaware a Certificate of Elimination of Series A Convertible Redeemable Preferred Stock and Series B Convertible Redeemable Preferred Stock (the “Certificate of Elimination”) to declassify those series of preferred stock as all shares of those classes had previously been repurchased. Other than the name change and the declassification of preferred stock, there were no changes to the Company’s certificate of incorporation or by-laws.
