INTRODUCTORY STATEMENT

This Amendment No. 1 (the “Amendment”) amends and supplements the Tender Offer Statement on Schedule TO (the “Schedule TO”) originally filed on January 10, 2022 with the United States Securities and Exchange Commission by Teekay Corporation, a Marshall Islands corporation (the “Company”).
