MEETING INFORMATION</div>

**Date, Time and Place

The Annual Meeting will be held on May 13, 2025, at 10:00 a.m. Eastern Time solely online via the Internet by going to www.virtualshareholdermeeting.com/STBA2025. To participate in the Annual Meeting, you will need the 16-digitcontrol number included on your Notice, on your proxy card or on the instructions that accompanied your proxy materials. See “Attending the Meeting; Virtual Meeting” below.

As permitted by S&T’s By-laws and applicable law, S&T will hold a virtual-only Annual Meeting. S&T will continue holding annual meetings in virtual-only format so long as shareholders are served well through this medium, which we believe enhances accessibility to our Annual Meeting for all of our shareholders.

Record Date, Voting Rights and Required Vote

The securities that can be voted at the Annual Meeting consist of shares of common stock of S&T, par value $2.50 per share (“Common Stock”), with each share entitling its owner to one vote on each matter to be voted on at the Annual Meeting. There are no cumulative voting rights with respect to the Common Stock. Only holders of the Common Stock at the close of business on February 28, 2025 (the “Record Date”) are entitled to notice of and to vote at the Annual Meeting. There were 38,370,213 shares of Common Stock outstanding as of the Record Date.

A quorum is required for the transaction of business at the Annual Meeting. A “quorum” is the presence at the meeting, virtually (i.e., online via www.virtualshareholdermeeting.com/STBA2025) or represented by proxy, of the holders of the majority of the outstanding shares of Common Stock entitled to vote at the meeting. Abstentions are counted for purposes of determining the presence or the absence of a quorum but are not considered a vote cast under Pennsylvania law. Under our governing documents and applicable state law, abstentions will not affect the outcome of a vote on a particular matter. Broker non-votesare counted to determine if a quorum is present but are not considered a vote cast under Pennsylvania law. Under our governing documents and applicable state law, broker non-voteswill not affect the outcome of a vote on a particular matter. Generally, broker non-votesoccur on a matter when a bank, broker or other nominee is not permitted to vote on that matter
