Material Event (Form 8-K)

As previously disclosed, on July 20, 2025, ZimVie Inc. (the "Company") entered into an Agreement and Plan of Merger (the "Merger Agreement") with Zamboni Parent Inc., a Delaware corporation ("Parent"), and Zamboni MergerCo Inc., a Delaware corporation and wholly owned subsidiary of Parent ("MergerCo"), pursuant to which, subject to the terms and conditions thereof, MergerCo will merge with and into the Company with the Company continuing as the surviving corporation and a wholly owned subsidiary of Parent (the "Merger"). Consummation of the Merger is subject to the approval of the Company's stockholders and other customary closing conditions. On September 2, 2025, the Company filed a definitive proxy statement (the "Proxy Statement") with the Securities and Exchange Commission ("SEC") in connection with the Merger.

Since the initial filing of the Proxy Statement, two complaints have been filed in the Supreme Court of the State of New York, County of New York, by purported Company stockholders against the Company and the members of the board of directors of the Company (the "Board") in connection with the Merger: Robert Williamsv. ZimVie Inc., et al., No. 655560/2025 (N.Y. Sup. Ct.) (filed September 17, 2025) and Richard McDanielsv. ZimVie Inc., et al., No. 655584/2025 (N.Y. Sup. Ct.) (filed September 18, 2025) (collectively, the "New York Stockholder Litigation"). In addition, one complaint has been filed in the Circuit Court of the Fifteenth Judicial Circuit in and for Palm Beach County, Florida, by a purported Company stockholder against, among others, the Company, members of the Board, Parent and MergerCo in connection with the Merger: Martin Siegelv. Asar, et al., No. 50-2025-CA-009567(Fla. Cir. Ct.) (filed September 17, 2025) (the "Florida Stockholder Litigation" and, together with the New York Stockholder Litigation, the "Stockholder Litigation"). Each of the complaints filed in the New York Stockholder Litigation includes allegations that, among other things, the Proxy Statement omitted certain material information, asserting claims for negligent misrepresentation and concealment in violation of New York common law and negligence in violation of New York common law. The complaint filed in the Florida Stockholder Litigation includes allegations that, among other things, the Proxy Statement omitted certain material information, asserting claims for violation of the New Jersey Uniform Securities Law (1997) and negligent misrepresentation and concealment and negligence in violation of Florida and New Jersey common law. Additionally, attorneys representing several purported Company stockholders have sent demand letters alleging similar insufficiencies in the disclosures in the Proxy Statement (such letters, the "Demand Letters" and, together with the Stockholder Litigation, the "Litigation Matters").

The complaints filed in the Stockholder Litigation seek various remedies, which include, among other things: (i) enjoining the defendants from proceeding with the proposed Merger unless and until the defendants disclose certain allegedly material information that was allegedly omitted from the Proxy Statement; (ii) enjoining or rescinding the closing of the stockholders vote concerning the proposed Merger until trial or until the defendants make corrective and complete disclosure or, in the event that the proposed Merger is consummated, rescinding it or awarding the plaintiff actual and punitive damages; (iii) awarding the plaintiffs the costs and disbursements of the action, including reasonable attorneys' and experts' fees and expenses; (iv) declaring that the defendants violated the New Jersey Uniform Securities Law (1997), that the defendants negligently misrepresented, concealed and omitted facts in the Proxy Statement or that the defendants were negligent and failed to exercise reasonable care or competence in communicating or failing to communicate truthfully and completely in the Proxy Statement, as applicable; and (v) granting such other and further relief as the court may deem just and proper.

It is possible that additional, similar complaints may be filed, that the complaints described above may be amended or that additional demand letters will be received by the Company. If this occurs, the Company does not intend to announce the filing or receipt of each additional, similar complaint or demand letter or any amended complaint unless required by law.

The Company believes that the allegations contained in the Litigation Matters are without merit and that no further disclosures are required to supplement the Proxy Statement under applicable laws. However, in order to avoid the risk of the Litigation Matters delaying or adversely affecting the Merger and to minimize the costs, risks and uncertainties inherent in litigation, and without admitting any liability or wrongdoing, the Company has determined to voluntarily make the following supplemental disclosures to the Proxy Statement as described in this Current Report on Form 8-K.Nothing in this Current Report on Form 8-Kshall be deemed an admission of the legal necessity or materiality under applicable laws of any of the disclosures set forth herein. To the contrary, the Company specifically denies all allegations in the Litigation Matters and that any additional disclosure was or is required.

These supplemental disclosures will not change the consideration to be paid to the Company stockholders in connection with the Merger or the timing of the special meeting of Company stockholders (the "Special Meeting") to be held on October 10, 2025, at 7:00 a.m., Mountain Time, at the Westin Denver International Airport located at 8300 Peña Blvd, Denver, CO 80249 (unless the Special Meeting is adjourned or postponed). The Board continues to unanimously recommend that you vote "FOR" the proposals to be voted on at the Special Meeting described in the Proxy Statement.
