• Transaction date: August 3, 2026; Form 4 filed August 5, 2026 (appears timely under the 2‑business‑day rule).
• Total shares sold: 120,000; total gross proceeds: ~ $4.90M.
• Sales were effected pursuant to a Rule 10b5‑1 trading plan adopted March 31, 2025 (footnote F1).

• Shares owned after the transactions are not specified in the excerpt provided — consult the full Form 4 or the issuer’s most recent proxy for updated ownership figures.

Context

• This is a sale by a 10% owner rather than an option exercise or a gift. Sales under pre‑arranged 10b5‑1 plans are commonly used to systematically sell shares and do not, by themselves, indicate the filer’s current view of company prospects.
• Retail investors tracking insider activity should note the size (~$4.9M) and that the plan and weighted‑average price footnotes mean the trades were executed in multiple child transactions across a stated price range.
