What Happened?

On August 15, 2025, Scorpion Capital published a report that described Soleno’s only product, Vykat XR, as overpriced and potentially unsafe for children. On this news, the price of Soleno shares declined by $5.73 per share, or approximately 7.41%, from $77.36 per share on August 14, 2025 to close at $71.64 on August 15, 2025.

Then on November 4, 2025, Soleno revealed during its quarterly earnings call that the discontinuation rate of Vykat XR related to adverse effects was approximately 8% at the end of the third quarter of fiscal 2025. Soleno’s Chief Executive Officer disclosed during the call that Soleno “did see a disruption in our [Vykat XR] launch trajectory in the wake of a short seller report that was released in mid-August [i.e, the Scorpion Capital report], mostly in the form of a lower number of start forms and increased discontinuations for non-serious adverse events. On this news, the price of Soleno shares declined by $16.98 per share, or approximately 26.59%, from $63.85 per share on November 4, 2025 to close at $46.87 on November 5, 2025.
