Background of the Investigation

On January 8, 2026, Beta Bionics announced preliminary, unaudited financial results and key operating metrics for the fourth quarter of 2025. The Company reported that new patient starts were expected to be at least 5,581 for the quarter, representing year-over-year growth of at least 36%. Despite the reported growth, the results were below reported analyst expectations and reflected a significant deceleration from the prior quarter, when Beta Bionics reported 68% year-over-year growth in new patient starts.

Investors reacted swiftly to the disclosure. On January 9, 2026, Beta Bionics’ stock price fell more than 35%, erasing substantial shareholder value and reflecting investor concern that the Company’s growth trajectory had slowed relative to expectations.

In light of this disclosure, Johnson Fistel is investigating whether Beta Bionics complied with federal securities laws. If you suffered losses, contact Johnson Fistel for more information.
