Explanatory Note

This Amendment No. 1 (this “Amendment”) amends the definitive proxy statement filed with the U.S. Securities and Exchange Commission on March 28, 2025 (the “2025 Proxy Statement”) regarding the 2025 Annual Meeting of Stockholders of AptarGroup, Inc. (“Aptar”) to be held May 7, 2025, including any adjournment or postponement thereof.

This Amendment is being filed solely to correct the chart on page 4 of the 2025 Proxy Statement, which incorrectly marked Stephan B. Tanda, Aptar’s President and CEO, as an independent member of Aptar’s Board of Directors. As correctly disclosed elsewhere in the 2025 Proxy Statement, Mr. Tanda is not independent in accordance with the listing standards of the New York Stock Exchange.

This Amendment should be read in conjunction with the 2025 Proxy Statement. Except as described in this Amendment, this Amendment does not modify, amend, supplement, or otherwise affect the 2025 Proxy Statement.
