• by Internet—You can vote over the Internet at www.proxyvote.com by following the instructions on the Notice and Access Card or proxy card;

• by Telephone—You can vote by telephone by calling 1-800-690-6903 and following the instructions on the proxy card; or

• by Mail—You can vote by mail by signing, dating and mailing the proxy card, which you may have received by mail.

Internet and Telephone voting facilities for stockholders of record will be available 24 hours a day and will close at 11:59 p.m., Eastern Time, on June 2, 2025.

If your shares are held in the name of a bank, broker or other holder of record, you will receive instructions on how to vote from the bank, broker or holder of record. You must follow the instructions of such bank, broker or holder of record in order for your shares to be voted.
