## 1) The disclosure record shows a “news vacuum” into the selloff PHIO’s most recent event-driven SEC disclosure ahead of the move was an 8‑K filed February 10, 2026, which simply furnished (via Item 8.01) the Company’s press release about the Safety Monitoring Committee’s conclusion for PH‑762—there is no indication in that filing of any contemporaneous adverse development, guidance reset, or regulatory setback.
