TABLE OF CONTENTS

Forward-Looking Statements

This proxy statement (this “Proxy Statement”) contains certain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. All statements other than statements of historical facts are forward-looking statements, including, without limitation, statements regarding the plans and expectations under its sustainability initiatives of ICU Medical, Inc. (the “Company”). In some cases, you can identify forward-looking statements by terms such as ‘‘may,’’ ‘‘will,’’ ‘‘should,’’ ‘‘expect,’’ ‘‘plan,’’ ‘‘anticipate,’’ ‘‘could,’’ “future,” “outlook,” “guidance,” ‘‘intend,’’ ‘‘target,’’ ‘‘project,’’ ‘‘contemplate,’’ ‘‘believe,’’ ‘‘estimate,’’ ‘‘predict,’’ ‘‘potential,’’ ‘‘continue,’’ or the negative of these terms or other similar expressions, although not all forward-looking statements contain these words.

These forward-looking statements are based on management’s current expectations and involve known and unknown risks and uncertainties that may cause actual future events to differ materially from the forward-looking statements in this Proxy Statement, including but not limited to the factors, risks and uncertainties included in the Company’s filings with the Securities and Exchange Commission (the “SEC”), including its Annual Report on Form 10-K for the fiscal year ended December 31, 2024, and as such factors may be updated from time to time in the Company’s other filings with the SEC, which are accessible on the SEC’s website atwww.sec.gov and the Investors Relations section of the Company’s website, www.icumed.com. These and other important factors could cause actual results to differ materially from those indicated by the forward-looking statements made in this Proxy Statement. Any such forward-looking statements represent management’s estimates as of the date of this Proxy Statement. While the Company may elect to update such forward-looking statements at some point in the future, unless required by applicable law, the Company disclaims any obligation to do so, even if subsequent events cause its views to change. Thus, one should not assume that the Company’s silence over time means that actual events are bearing out as expressed or implied in such forward-looking statements. These forward-looking statements should not be relied upon as representing the Company’s views as of any date after the date of this Proxy Statement.
