Septerna President and COO Elizabeth Bhatt exercised 4,000 options at $6.81 and sold 4,000 common shares at about $33.99 on July 15, 2026 under a Rule 10b5-1 plan.

On July 15, 2026, Septerna, Inc. President and COO Elizabeth Bhatt exercised 4,000 stock options at $6.81 per share and immediately sold the same 4,000 shares of common stock at a weighted average price of $33.9935 per share under a pre-established Rule 10b5-1 trading plan, resulting in an approximate gross sale value of about $136,000 and an intrinsic gain of about $108,700. The option exercise, with a zero reported exercise cost in the derivative table but a stated option price of $6.81, reflects ongoing vesting from an option grant that vests in equal monthly installments over 48 months from October 28, 2024, and appears structured as a sell-to-cover or liquidity event. Following these transactions, Bhatt’s direct common stock holdings changed from 178,209 shares to 174,209 shares in one table, while the derivative table shows 80,911 shares of common stock underlying options remaining exercisable, indicating she retains a meaningful equity stake despite the modest, pre-planned sale.
