Important Additional Information The Company and certain of its directors and executive officers are deemed to be “participants” (as defined in Section 14(a) of the Securities Exchange Act of 1934, as amended) in the solicitation of proxies from the Company’s shareholders in connection with the Company’s 2025 Annual Meeting of Shareholders (the “Annual Meeting”). The Company filed its definitive proxy statement (the “Definitive Proxy Statement”) and a WHITE universal proxy card with the U.S. Securities and Exchange Commission (the “SEC”) on December 3, 2024 in connection with such solicitation of proxies from the Company’s shareholders. SHAREHOLDERS OF THE COMPANY ARE STRONGLY ENCOURAGED TO READ SUCH DEFINITIVE PROXY STATEMENT, ACCOMPANYING WHITE UNIVERSAL PROXY CARD AND ALL OTHER DOCUMENTS FILED WITH THE SEC CAREFULLY AND IN THEIR ENTIRETY AS THEY CONTAIN IMPORTANT INFORMATION ABOUT THE ANNUAL MEETING. The Definitive Proxy Statement contains information regarding the identity of the participants, and their direct and indirect interests, by security holdings or otherwise, in the Company’s securities and can be found in the appendix titled “Supplemental Information Regarding Participants in the Solicitation” of the Definitive Proxy Statement and available here. Information regarding subsequent changes to their holdings of the Company’s securities can be found in the SEC filings on Forms 3, 4, and 5, which are available on the Company’s website available here or through the SEC’s website at www.sec.gov. Shareholders will be able to obtain the Definitive Proxy Statement, any amendments or supplements thereto and other documents filed by the Company with the SEC at no charge at the SEC’s website at www.sec.gov. Copies will also be available at no charge at the Company’s website at https://investors.airproducts.com. Cautionary Statement The timing of these postings are made at the discretion of the Company.
