To Our Stockholders:

You are cordially invited to attend the 2026 Annual Meeting of Stockholders of iRhythm Holdings, Inc. (the “Annual Meeting”), which will be held virtually at www.virtualstockholdermeeting.com/IRTC2026 on Wednesday, May 27, 2026, at 9:00 a.m. Pacific Time. We believe that a virtual stockholder meeting provides greater access to those who may want to attend and therefore we have chosen this over an in-person meeting. This approach also lowers costs and enables participation from our global community. The matters expected to be acted upon at the Annual Meeting are described in the accompanying Notice of Annual Meeting of Stockholders and Proxy Statement. The Annual Meeting materials include the Notice of Annual Meeting of Stockholders, Proxy Statement, and Annual Report to stockholders, each of which has been furnished to you over the internet or, if you have requested a paper copy of the materials, by mail.

Your vote is important. Whether or not you plan to attend the Annual Meeting, please cast your vote as soon as possible by Internet, telephone or, if you received a paper copy of the meeting materials by mail, by completing and returning the enclosed proxy card in the postage-prepaid envelope to ensure that your shares will be represented. Your vote by written proxy will ensure your representation at the Annual Meeting regardless of whether or not you attend virtually. Returning the proxy does not affect your right to attend the Annual Meeting or to vote your shares at the Annual Meeting.

Sincerely,

/s/ Quentin S. Blackford

Quentin S. Blackford

Chief Executive Officer
