Material Event Form 8 K

As previously disclosed, on January 12, 2023, Bioventus Inc. (the "Company" or "Bioventus") and certain of its current and former directors and officers were named as defendants in a putative class action lawsuit filed in the Middle District of North Carolina (the "Court), Ciarciello v. Bioventus, Inc., No. 1:23- CV - 00032-CCE-JEP(M.D.N.C. 2023). The complaint asserted violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended (the "Exchange Act") and of Sections 11 and 15 of the Securities Act of 1933, as amended (the "Securities Act") and generally alleged that the Company failed to disclose certain information regarding rebate practices, its business and financial prospects, and the sufficiency of internal controls regarding financial reporting. The complaint sought damages in an unspecified amount. On April 12, 2023, the Court appointed Wayne County Employees' Retirement System as lead plaintiff. The plaintiff's amended consolidated complaint was filed with the Court on June 12, 2023. On July 17, 2023, the defendants filed a motion to dismiss the complaint raising a number of legal and factual deficiencies with the amended consolidated complaint. In response to the defendants' motion to dismiss, the lead plaintiff filed a second amended complaint on July 31, 2023. The defendants moved to dismiss the second amended complaint on August 21, 2023, which the Court granted in part and denied in part on November 6, 2023. The Court dismissed the plaintiff's Securities Act claims, but allowed the plaintiff's Exchange Act claims to proceed into discovery.

On July 15, 2024, a Stipulation and Agreement of Settlement (the "Settlement Agreement") by and between the lead plaintiff and the defendants was filed with the Court. The Settlement Agreement, which is subject to Court approval, provides among other things for (i) the dismissal of all claims against the defendants, including the Company; (ii) a settlement amount of $15.25 million, together with interest earned thereon, to be paid by the defendants and/or the defendant's insurers within 30 days after the later of the date of entry by the Court of an order preliminarily approving the terms of the settlement or receipt by the defendants from lead counsel of the information necessary to effectuate a transfer of the settlement funds; and (iii) no admission of liability or wrongdoing by any party. The Company expects approximately $6.5 million of the settlement amount to be paid by its insurers, subject to ongoing costs and fees.
