Insights

Financial Analyst

TL;DR: Insider reported both a purchase and a substantial sale on the same date, producing mixed signals for investors.

The Form 4 discloses a 27,778-share acquisition at $9.00 and a 138,495-share disposition by Leonard Mertz on 08/18/2025, with 121,503 shares held indirectly via a trust after the purchase.
