Annual Meeting of Shareholders

March 25, 2026

To Our Shareholders:

We welcome you to join us at our 2026 Annual Meeting of Shareholders to be held virtually on Friday, May 8, 2026, at 9:00 a.m., EDT. This proxy statement provides more information regarding the virtual-only meeting and the business we will conduct at the annual meeting.

Shareholders will be able to attend and participate in the annual meeting, including voting their shares and asking questions from any remote location with Internet connectivity. Information on how to participate in this year’s annual meeting can be found on page 2 of this proxy statement. At this year’s meeting, you are being asked to consider and act upon each of the following items:

1. to elect the seven directors identified in the proxy statement;

2. to conduct a non-binding advisory vote on the compensation of our named executive officers;

3. to ratify the appointment of KPMG LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2026; and

4. to transact such other business as may properly come before the meeting or any adjournments or postponements thereof.

We are using the Securities and Exchange Commission rule for Notice and Access that allows companies to furnish proxy materials to their shareholders over the Internet. You are therefore receiving a Notice of Internet Availability of Proxy Materials rather than a paper copy of our proxy statement and our Annual Report on Form 10-K for the fiscal year ended December 31, 2025. The Notice of Internet Availability explains how to access the proxy materials online, vote online, and obtain a paper copy of our proxy materials, if desired.

On behalf of the Board of Directors, management, and employees of Tredegar Corporation, I thank you for your continued support and confidence in our company.

Sincerely yours,

Gregory A. Pratt

Chairman of the Board
