**Meeting Information

Householding

The SEC has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for Notices or proxy statements and annual reports with respect to two or more shareholders sharing the same address by delivering a single Notice or proxy statement and annual report addressed to those shareholders. This process is commonly referred to as “householding.”

S&T has implemented “householding” to reduce the number of duplicate mailings to the same address. This process benefits both shareholders and S&T because it eliminates unnecessary mailings delivered to your home and helps to reduce S&T’s expenses. “Householding” is not being used, however, if S&T has received contrary instructions from one or more of the shareholders sharing an address. If your household has received only one Notice or one annual report and proxy statement, S&T will deliver promptly a separate copy of the Notice or annual report and proxy statement to any shareholder who contacts S&T by calling the toll-free number, 1-800-325-2265, or by mail to the attention of the Secretary of S&T at 800 Philadelphia Street, Indiana, Pennsylvania 15701. You can also notify S&T that you would like to receive separate copies of the Notice or S&T’s annual report and proxy statement in the future by calling or mailing S&T, as instructed above. If your household has received multiple copies of the Notice or S&T’s annual report and proxy statement, you can request the delivery of single copies in the future by calling or mailing S&T, as instructed above, or your broker, if you hold the shares in “street name.”

If you received more than one Notice or proxy card, it means that your shares are registered in more than one name (e.g., trust, custodial accounts, joint tenancy) or in multiple accounts. Please make sure that you vote all of your shares by following the directions on each Notice or on each proxy card
