Insights

Rothblatt’s Form 4 shows a planned exercise-and-sell transaction with sizable remaining holdings.

Martine Rothblatt, Chairperson & CEO of United Therapeutics, exercised stock options for 9,500 shares at an exercise price of $146.03 and sold the same number of shares in open-market trades around the low $500s.

The filing specifies these actions occurred under a pre-arranged Rule 10b5-1 trading plan adopted on November 7, 2025, which is scheduled to continue until the earlier of exercising 1,734,410 options expiring on March 17, 2027 or December 31, 2026. Such plans are designed to systematize selling activity.

After the trades, Rothblatt still owns 40,513 shares directly and has substantial indirect holdings through her spouse and family trusts, including positions of 324,518, 258,117, 45,596, and 10,962 shares in various trusts. Given the pre-planned nature and large remaining stake, this filing appears as routine liquidity management rather than a thesis-changing move.
