Key Details

• Transaction date and price: 2026-08-17 — 27,505 shares at $9.21 each (total ≈ $253,321).
• Filing date: Form 4 filed 2026-08-19; this appears timely (filed within two business days).

Context
A 10b5-1 plan allows insiders to sell shares on a pre-arranged schedule and commonly reduces the extent to which a sale is interpreted as a reaction to inside information. For retail investors, purchases tend to be more informative of insider confidence than scheduled sales; this transaction should be viewed as routine unless other material disclosures suggest otherwise.
