Explanatory Note: On February 12, 2024, Mr. R. Phillip Silver and Mr. Greg D. Horrigan entered into a Joint Filing Agreement pursuant to which they agreed to jointly file a Schedule 13G, as permitted by Rule 13d-1(k)(1) promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), to report their respective ownership of Common Stock, $0.01 par value, of Silgan Holdings Inc. (the “Common Stock”). On November 14, 2024, as a result of the new quarterly filing requirements for Schedule 13G, Mr. Silver and Mr. Horrigan mutually agreed to terminate such Joint Filing Agreement and no longer report their respective beneficial ownership of Common Stock on a joint filing on Schedule 13G as permitted by Rule 13d-1(k)(1) promulgated under the Exchange Act. Mr. Silver and Mr. Horrigan will now instead report their respective beneficial ownership of Common Stock on a Schedule 13G (or amendment thereto) filed by each reporting person separately or as otherwise required in accordance with the federal securities laws. As reported below, Mr. Silver and Mr. Horrigan do not file or act as a group (as that term is defined under Section 13D of the Exchange Act and the rules thereunder). This Schedule 13G reports Mr. Horrigan’s beneficial ownership of Common Stock as of September 30, 2024 and the termination of the Joint Filing Agreement as discussed above. Mr. Horrigan’s beneficial ownership of Common Stock as of December 31, 2023 was reported in Amendment 21 to Schedule 13G filed with the Securities and Exchange Commission on February 12, 2024.
