  • Transaction type/code: Open market purchase (P).
  • Shares purchased: 1,000; weighted-average price: $10.19; total value ≈ $10,190.
  • Price range: purchases occurred at prices between $9.99 and $10.34 (weighted average reported). The filer offers to provide a breakdown of how many shares were bought at each price upon request.

Context
Insider purchases are often watched by retail investors as a potential sign of confidence, but they can also occur under pre-set 10b5-1 plans that schedule trades in advance. This purchase was executed under such a plan (adopted 12/05/2025), which can reduce the extent to which the trade reflects new, real-time insider sentiment.
