CBIZ Terminates Eight Legacy Registration Statements After Viking Merger Closes

According to the filing, CBIZ, Inc. (NYSE:CBZ), a Delaware corporation headquartered at 5959 Rockside Woods Blvd. N., Suite 600, Independence, Ohio 44131, completed a merger on November 2, 2026. Under the terms of the Agreement and Plan of Merger dated July 28, 2026, Viking MergerCo, Inc., a direct wholly owned subsidiary of Viking ParentCo, Inc., merged with and into CBIZ, with CBIZ continuing as the surviving entity and becoming a wholly owned subsidiary of Parent. The filing states that the company is classified as a large accelerated filer.

The filing discloses that, as a result of the merger, "any and all offerings of securities registered pursuant to the Registration Statements have been terminated." In accordance with undertakings made by the company in each of the eight registration statements, CBIZ filed these Post-Effective Amendments to remove from registration all securities that remained unsold as of November 2, 2026. Those securities span a broad range of instruments, including shares of common stock registered for resale by selling stockholders under statements dating as far back as November 1, 1996, when the company operated under its former name, International Alliance Services, Inc., as well as a $125,000,000 shelf covering debt securities, common stock, and warrants under Registration No. 333-40331, and the 3.125% Convertible Senior Subordinated Notes due 2026 under Registration No. 333-135912, filed on July 21, 2006.

The filing further states that "the Registration Statements are hereby amended, as appropriate, to reflect the deregistration of such securities, and the Company hereby terminates the effectiveness of the Registration Statements." The company operated under several former names over the decades covered by these registrations, including International Alliance Services, Inc. and Century Business Services, Inc., before adopting the CBIZ, Inc. name. No further sales of securities under any of the eight registration statements will occur following this action.
