Explanatory Note

On March 26, 2025, Edwards Lifesciences Corporation (the “Company”) filed a definitive proxy statement (the “Proxy Statement”) with the Securities and Exchange Commission for the Company’s 2025 Annual Meeting of Stockholders to be held on May 8, 2025 (the “Annual Meeting”). The Company is filing this supplement (this “Supplement”) to its Proxy Statement solely to clarify disclosure included in the “Vote Required on Proposals” table in the “General Meeting and Voting Information” section of the Proxy Statement. Except as specifically updated by the information contained below, all information set forth in the Proxy Statement remains unchanged.

Voting Information

As disclosed in the Proxy Statement, broker non-votes will not be counted as votes cast for Proposal 1 and will not be counted as shares entitled to vote on Proposals 2, 3, 4, and 5. This necessarily means that broker non-votes with respect to these proposals will have no effect on the outcome of the proposals at the Annual Meeting. This Supplement is being filed solely to clarify the effect of this treatment on the proposals by replacing the “Vote Required on Proposals” table on pages 3-4 of the Proxy Statement with the following:
