On August 11, 2026, Septerna, Inc. President and COO Elizabeth Bhatt exercised two tranches of stock options for a total of 25,000 shares of common stock (18,681 shares at an exercise price of $6.81 and 6,319 shares at $2.76), and on the same day sold 25,000 shares of common stock at $44.00 per share pursuant to a pre-arranged Rule 10b5-1 trading plan. The option exercises, reported as transactions coded “M,” resulted in new share issuances that increased her direct holdings before the sale, while the subsequent open market sale, coded “S,” reduced her direct ownership to 174,209 shares. The exercised options had no remaining option value reported (exercise price fully paid), and the Form 4 footnotes describe standard monthly vesting schedules for the underlying option awards, indicating these were routine compensation-related exercises coupled with liquidity sales under a structured plan rather than discretionary, opportunistic trading.
