Q2 2026 earnings summary12 Feb, 2026

Executive summary

  • Focused on late-stage development of biologics for rare diseases, especially hyperinsulinism (HI).

  • Phase 3 sunRIZE trial for congenital HI did not meet primary or key secondary endpoints, though some efficacy signals were observed; all 59 participants entered the open-label extension, with many continuing on ersodetug monotherapy.

  • Phase 3 upLIFT trial for tumor HI is ongoing, with topline results expected in the second half of 2026.

  • Reduction in workforce by 29 employees in December 2025 to conserve cash after sunRIZE results.

Financial highlights

  • Net loss of $22.8 million for the quarter and $40.9 million for the six months ended December 31, 2025, compared to $15.7 million and $31.1 million in the prior year periods.

  • Operating expenses increased to $24.2 million for the quarter and $44.0 million for the six months, driven by higher R&D and G&A costs, including $1.5 million in one-time severance.

  • Cash, cash equivalents, and investments totaled $132.9 million as of December 31, 2025, down from $167.9 million as of June 30, 2025.

  • Working capital was $125.6 million as of December 31, 2025.

Outlook and guidance

  • Management believes current capital resources are sufficient to fund operations and planned activities for at least 12 months from the reporting date.

  • Additional equity or debt financing will be needed to meet long-term obligations and fund future development.

  • FDA meeting for congenital HI program expected by end of Q1 2026 under Breakthrough Therapy Designation; outcome may impact future plans and cash needs.

excellent app, it gives me free access to company earnings calls and annual reports. I also love the convenience of calls being available offline so I can listen in whilst doing other things and even when internet or WiFi isn't available.

One of the very few apps you could call perfect. If something was to add to it, maybe the share price of the company when you search for it, but it's already excellent.
