On April 16, 2025, J. Drayton Wise notified Insmed Incorporated (the “Company”) of his decision to resign from his position as the Company’s Chief Commercial Officer for personal and medical reasons, effective immediately. Mr. Wise’s resignation was not related to the Company’s financial or operating results or to any disagreements or concerns between Mr. Wise and the Company regarding the Company’s operations, policies, or practices.

Mr. Wise will continue to provide consulting services to the Company following his resignation as described in the consulting agreement entered into between Mr. Wise and the Company on April 16, 2025 (the “Consulting Agreement”). Mr. Wise will be reasonably available to provide consulting services to the Company until December 31, 2025 (the “Initial Consulting Period”), subject to automatic extension for two three-month periods unless the Consulting Agreement is terminated by mutual agreement of Mr. Wise and the Company (each such additional period, an “Extension Period” and together with the Initial Consulting Period, the “Consulting Period”).

Pursuant to and conditioned upon Mr. Wise’s compliance with the Consulting Agreement, (a) Mr. Wise will receive a consulting fee of $30,000 per month during the Initial Consulting Period, (b) Mr. Wise will receive a consulting fee of $20,000 per month during each Extension Period, and (c) Mr. Wise’s outstanding equity awards will continue to vest during the Consulting Period. In accordance with the Company’s equity incentive plans and Mr. Wise’s grant agreements, his stock options will continue to be exercisable, to the extent vested, until the earlier of the three months following the last day of his service relationship with the Company and the original 10-year expiration date for such vested options.
