Employee Email with Voting Instructions

From: Brian Walters

To: Global Employees

Date: Wednesday, January 15, 2025

Subject: IMPORTANT UPDATE: Please Vote the WHITE Proxy Card for Matthews’ Board Nominees!

Dear Colleagues,

As you likely have seen, Matthews’ Annual Shareholder Meeting will be held virtually on February 20, 2025 (at 9:00 a.m. Eastern Time). We want to ensure that any Matthews employee who owns stock in the Company has the correct information to vote their shares at the upcoming Annual Meeting.

One of our shareholders, Barington Capital, recently nominated candidates to stand for election to our Board of Directors at our upcoming Annual Meeting. You may receive written communications or phone calls from Barington and its representatives encouraging you to vote at the Annual Meeting.

• The Matthews Board and Management Team strongly urges you to ignore any communications or proxy materials from Barington.

• The Matthews Board and Management Team also strongly recommends that all shareholders only use the WHITE proxy card to vote FOR all three Matthews nominees.

• If you complete the WHITE proxy card to vote FOR all three Matthews nominees, nothing else is necessary.

We encourage all employee shareholders to vote by proxy prior to the Company’s Annual Meeting. Your vote is important, no matter how many shares you own – and voting is quick and easy. You can vote by internet, by phone or by signing, dating and returning the WHITE proxy card in the postage-paid envelope that has been mailed to you.

If you have additional questions or need assistance in voting your shares, please call our proxy solicitor, Georgeson, by phone (888) 755-7097 or email at MATWinfo@Georgeson.com.

Thank you,

Brian
