  • No new August 26, 2026 company-specific announcement, earnings release, or analyst action was found; the latest listed update was participation in the H.C. Wainwright conference on August 18.
  • The August 13 earnings update disclosed a Proteus launch delay to Q2 2027 and workforce reductions, but available sources do not directly connect that prior news to today’s decline.
  • Broader market indexes are slightly lower, but not enough to establish a clear cause.
