Beta Bionics, Inc.

From time to time, we may become involved in legal proceedings arising in the ordinary course of our business. In September 2026, a purported stockholder of our company filed a securities class action against our company and certain of our executive officers in the United States District Court for the Central District of California, captioned Holtzman vs. Beta Bionics, Inc. et al., Case No. 8:26-cv-2612-JWH (KESx). The complaint alleges that defendants violated Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, and SEC Rule 10b-5 promulgated thereunder, by making material misstatements or omissions concerning the safety, efficacy, and commercial success of iLet. The complaint seeks, on behalf of the putative class, unspecified damages, pre- and post-judgment interest, attorneys’ fees, expert fees and costs, as well as class certification and such other relief as the court may deem just and proper. We intend to vigorously defend against the claims in this action. Any potential loss arising from this claim is not currently probable or estimable.
