The sales and issuances of the Shares authorized by the Amendment to Sale Agreement will be made pursuant to the Company’s effective shelf registration statement on Form S-3ASR (File No.333-278770) (the “Registration Statement”), that was automatically effective upon filing with the SEC on April 17, 2024, as supplemented by the Prospectus Supplement.
