Sotheara Cheav executes 7 sales totaling 18,750 shares for $1,585,923.42 ($1.6M) under pre-arranged 10b5-1 plan

Sotheara Cheav sold 18,750 shares across 7 separate transactions on June 4–5, 2026 at prices ranging from $81.73 to $85.77, raising $1,585,923.42. This activity was pre-arranged under a 10b5-1 trading plan adopted on 2026-03-05, meaning the sales were scheduled and not discretionary responses to current market conditions. Post-transaction, Cheav retains 100,002 non-derivative shares and holds an additional 80,399 shares via derivative securities (two stock option grants: 42,899 and 37,500 shares), so the position remains active despite the sale. The sales occurred during a period of significant momentum—the stock has gained 37.8% in the 30-day period and 69.8% over 90 days, recovering substantially from its 52-week low. Investors should note that the 10b5-1 framework removes any inference of timing-based decision-making; the trades follow a pre-set schedule established three months prior.
