UNITED THERAPEUTICS Corp President and COO Michael Benkowitz reported routine equity compensation activity involving restricted stock units and common shares. On March 15, 2026, a trust associated with him exercised restricted stock units that each convert into one share of common stock, resulting in 33,382 shares of common stock held indirectly by the trust.

Of these shares, 14,706 shares of common stock were withheld by United Therapeutics to satisfy tax obligations upon vesting, a non-market disposition that does not represent an open-market sale. Following these transactions, the filing shows 19,046 shares held indirectly by the trust and 2,710 shares held directly, which includes 62 shares acquired earlier under the company’s employee stock purchase plan.

United Therapeutics Corp CFO and Treasurer James Edgemond exercised restricted stock units into 19,478 shares of common stock on March 15, 2026. These awards converted one-for-one into common shares following vesting, reflecting performance-based and time-based equity compensation.

To cover tax obligations at vesting, 8,786 shares were withheld by United Therapeutics at a price of $536.12 per share. These F-code transactions are tax-withholding dispositions, not open-market sales. After all transactions, Edgemond directly holds 18,876 shares of common stock, including 42 shares acquired under the employee stock purchase plan.

United Therapeutics EVP & General Counsel Paul A. Mahon reported the vesting and conversion of restricted stock units into common shares. On March 15, 2026, 16,691 restricted stock units converted on a one-for-one basis into 16,691 shares of common stock, reflecting time- and performance-based awards granted in March 2023.

To cover tax obligations upon vesting, 8,363 of these shares were withheld by United Therapeutics at a reference price of $536.12 per share, rather than sold in the open market. After these transactions, Mahon directly owns 45,172 shares of United Therapeutics common stock.

United Therapeutics Chairperson and CEO Martine A. Rothblatt reported vesting and settlement of restricted stock units rather than open-market trades. On March 15, 2026, she exercised and converted a total of 69,579 restricted stock units into the same number of common shares on a one-for-one basis.

To cover tax obligations associated with these vestings, 29,196 common shares were withheld by United Therapeutics at $536.12 per share, a non-market tax-withholding disposition. After these transactions, Rothblatt directly held 40,513 shares of common stock, and the filing also shows additional indirect holdings through her spouse and various family trusts.

United Therapeutics director Jan Malcolm reported an open-market sale of company stock. On March 17, 2026, Malcolm sold 45 shares of Common Stock at an average price of $533.51 per share, and now directly holds 125 shares. The sale was executed under a pre-arranged Rule 10b5-1 trading plan that Malcolm entered into on September 11, 2025, indicating the transaction was scheduled in advance rather than timed discretionarily.
