HANISH ARNOLD C 4

What Happened
Arnold C. Hanish, a non-employee director of Omeros Corporation (OMER), received a grant of an option covering 15,000 shares on June 18, 2026. The Form 4 shows acquisition price as $0.00 (standard notation for a stock option award) and this is a derivative award, not an immediate purchase of common stock. The grant was made under Omeros’ non-employee director compensation policy and will fully vest and become exercisable the day before the 2027 annual meeting provided Hanish continues to serve as a director.

Context
This is a routine director compensation award rather than an outright purchase or sale of stock. Option grants are commonly used to align directors’ interests with shareholders but do not represent immediate stock ownership or a direct market bet. The Form 4 does not disclose exercise price or other economic terms beyond the award size and vesting condition; those details may be in the option agreement or a separate disclosure.
