 may properly come before the Annual Meeting or any adjournments or postponements thereof.

Our Board of Directors has fixed the close of business on March 17, 2025 as the record date for the Annual Meeting. Only stockholders of record on March 17, 2025 are entitled to notice of and to vote at the Annual Meeting. Further information regarding voting rights and the matters to be voted upon is presented in the accompanying proxy statement.

We are pleased to be furnishing proxy materials to stockholders primarily over the Internet for our Annual Meeting. Consequently, most stockholders will not receive paper copies of our proxy materials. We will instead send to our stockholders a Notice of Internet Availability of Proxy Materials. We believe that this process expedites stockholders’ receipt of proxy materials, lowers the costs of our Annual Meeting, and conserves natural resources.

On or about March 27, 2025, we expect to mail to our stockholders a Notice of Internet Availability of Proxy Materials containing instructions on how to access our proxy statement for our Annual Meeting and our 2024 annual report to stockholders (“Annual Report”). The Notice of Internet Availability of Proxy Materials also includes instructions on how you can vote using the Internet and how you can request and receive, free of charge, a printed copy of our proxy materials. Our proxy statement and our Annual Report can be accessed directly at the following Internet address: http://www.proxyvote.com by entering the control number located on your proxy card. All stockholders who do not receive a Notice of Internet Availability of Proxy Materials will receive a paper copy of the proxy materials by mail.

YOUR VOTE IS IMPORTANT. Whether or not you plan to attend the virtual Annual Meeting of Stockholders, we urge you to submit your vote via the Internet, telephone or mail.

On behalf of the Board of Directors, I would like to express our appreciation for your interest in Inogen.

Sincerely,

Kevin R.M. Smith
