<div align='center'>**IMPORTANT NOTICE REGARDING THE AVAILABILITY OF

PROXY MATERIALS FOR THE 2025 ANNUAL MEETING OF SHAREHOLDERS

TO BE HELD ON MAY 13, 2025: OUR PROXY STATEMENT, 2024 ANNUAL REPORT AND NOTICE OF

ANNUAL MEETING OF SHAREHOLDERS ARE AVAILABLE ATWWW.PROXYVOTE.COM**</div>

We are taking advantage of a rule of the Securities and Exchange Commission (the “SEC”) which allows companies to make proxy materials available on a public website rather than in paper form. This rule allows a company to send some or all of its shareholders a Notice of Internet Availability of Proxy Materials in place of the complete proxy package. For our 2025 Annual Meeting, to save significant printing and mailing expenses, S&T mailed a Notice to certain shareholders who had not previously elected to receive their proxy materials through the mail on or about March 31, 2025, to inform them of the electronic availability of the proxy materials 40 days in advance of the Annual Meeting.
