Item 8.01 Other Events. On May 22, 2026, the Company filed (i) a certificate of conversion with the Secretary of State of the State of Delaware and (ii) a certificate of conversion and certificate of formation with the Secretary of State of the State of Texas, pursuant to which the re-domestication of the Company from the State of Delaware to the State of Texas (“Re-domestication”) pursuant to a plan of conversion the “Plan of Conversion” became effective on May 22, 2026 (the “Effective Time”). At the Effective Time: (i) the Company’s state of incorporation changed from the State of Delaware to the State of Texas; and (ii) the affairs of the Company ceased to be governed by the laws of the State of Delaware and the Company’s existing restated certificate of incorporation and amended and restated bylaws, and instead became governed by the laws of the State of Texas and the certificate of formation filed with the Secretary of State of the State of Texas (“Texas Charter”) and the bylaws approved by the Company’s board of directors (“Texas Bylaws”). The Re-domestication did not result in any change in the business, jobs, management, properties, location of any of the Company’s offices or facilities, number of employees, obligations, assets, liabilities, or net worth (other than as a result of the costs related to the Re-domestication). The Re-domestication did not materially affect any of the Company’s material contracts with any third parties, and the Company’s rights and obligations under those material contractual arrangements continue to be the rights and obligations of the Company after the Re-domestication. At the Effective Time, each outstanding share of Common Stock, par value $0.01 per share, of the Delaware corporation (“Delaware Corporation Common Stock”) automatically converted into one outstanding share of common stock, par value $0.01 per share, of the Texas corporation (“Texas Corporation Common Stock”). Stockholders do not have to exchange their existing stock certificates for new stock certificates. At the Effective Time, each outstanding restricted stock unit or other right to acquire shares of Delaware Corporation Common Stock automatically became a restricted stock unit or other right to acquire an equal number of shares of Texas Corporation Common Stock, under the same terms and conditions. The Texas Corporation Common Stock continues to be traded on The Nasdaq Stock Market under the symbol “TTEC.” Certain rights of the Company’s stockholders were changed as a result of the Re-domestication. A more detailed description of the Plan of Conversion, Texas Charter, Texas Bylaws, and the effects of the Re-domestication is set forth in the Company’s definitive proxy statement on Schedule 14A for the Annual Stockholders Meeting filed with the Securities and Exchange Commission on April 10, 2026 under “Proposal No. 4 Approval of the Redomestication of the Company from Delaware to Texas by Conversion,” which description is incorporated herein by reference. Copies of the Plan of Conversion, Texas Charter and Texas Bylaws are filed as Exhibits 2.2, 3.1 and 3.2, respectively, to this Current Report on Form 8-K and are incorporated herein by reference.
