Item 8.01 – Other Events.

On November 30, 2019, pursuant to the terms and conditions of the Agreement and Plan of Merger, dated as of June 5, 2019 (the “Merger Agreement”), by and between S&T Bancorp, Inc. (“S&T”) and DNB Financial Corporation (“DNB”), DNB merged with and into S&T (the “Merger”), with S&T continuing as the surviving corporation.  Immediately following the Merger, DNB First, National Association, a wholly owned bank subsidiary of DNB, merged with and into S&T Bank, a Pennsylvania bank and wholly owned subsidiary of S&T (such merger, the “Bank Merger”), with S&T Bank as the surviving entity in the Bank Merger.

Under the terms and subject to the conditions of the Merger Agreement, at the effective time of the Merger (the “Effective Time”), each share of the common stock, par value $1.00 per share, of DNB (“DNB Common Stock”) issued and outstanding immediately prior to the Effective Time (except for certain shares cancelled in accordance with the Merger Agreement), was converted into the right to receive, without interest, 1.22 shares of common stock, par value $2.50 per share, of S&T (“S&T Common Stock”)(such amount the “Merger Consideration”).  In addition, at the Effective Time, each award of restricted shares of DNB Common Stock vested in full, and converted into the right to receive the Merger Consideration (less applicable tax withholdings) in respect of each share of DNB Common Stock underlying such award.  No fractional shares of S&T Common Stock were issued in the Merger; DNB shareholders became entitled to receive cash in lieu of fractional shares.

The foregoing description of the Merger and the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement, which is attached as Exhibit 2.1 to S&T’s Current Report on Form 8-K filed with the Securities and Exchange Commission (the “Commission”) on June 5, 2019 and incorporated herein by reference.

As previously disclosed, in connection with the Merger, the board of directors (the “Board”) of S&T appointed two new members, William (Bill) J. Hieb and Peter R. Barsz, to the Board, effective as of immediately after the Effective Time.  For additional description of these appointments, please see S&T’s Current Report on Form 8-K filed with the Commission on October 24, 2019 (the second Current Report on Form 8-K filed by S&T on such date).
