Omeros Director Thomas Cable Exercises Options, Sells 15,000 Shares

What Happened

• Thomas J. Cable, a director of Omeros Corporation (OMER), exercised options to acquire 15,000 common shares (7,500 at $2.00 and 7,500 at $3.93) for a combined exercise cost of $44,475. The same day he sold 15,000 shares in an open-market transaction for a reported weighted average price of $18.45, generating proceeds of about $276,773. The filing also includes two derivative-disposition entries reported at $0 (see Key Details).

Key Details

• Transaction date: August 20, 2026.
• Option exercises (acquired): 7,500 shares @ $2.00 ($15,000); 7,500 shares @ $3.93 ($29,475) — total exercise outlay $44,475.
• Open-market sale (disposed): 15,000 shares @ weighted avg $18.45 ≈ $276,773. Footnote F1: actual sale prices ranged $18.23–$18.72; $18.45 is the weighted average.
• Two additional derivative disposals are reported at $0 for 7,500 shares each (listed as derivative dispositions in the filing).
• Shares owned after the transactions: not specified in the provided Form 4 details.
• Filing date: August 21, 2026 (filed the business day after the transactions) — appears timely under standard Form 4 rules.

Context

• The pattern—exercising options and selling an equal number of shares the same day—is commonly a cashless exercise or immediate disposition to cover exercise cost/taxes or realize gains; the Form 4 shows the exercises and the contemporaneous open-market sale but does not state motive.
• These transactions are by a non-executive director (not a 10% owner per the information provided). Retail investors should view purchases as more indicative of bullish insider sentiment; same-day exercise-and-sell transactions are often routine and primarily tax/finance-driven.
