CURRENT REPORT ON FORM 8-K

ITEM 2.01                                  Completion of Acquisition or Disposition of Assets

Effective July 1, 2017, ACNB Corporation (the “Corporation”) completed its previously- announced acquisition of New Windsor Bancorp, Inc. (“NW Bancorp”) pursuant to an Agreement and Plan of Reorganization dated as of November 21, 2016, as amended, by and among the Corporation, ACNB South Acquisition Subsidiary, LLC (“Acquisition Subsidiary”), ACNB Bank, NW Bancorp, and New Windsor State Bank (“NWS Bank”) (the “Reorganization Agreement”). At the effective time of the merger, NW Bancorp merged with and into Acquisition Subsidiary with Acquisition Subsidiary surviving the merger. In addition, NWS Bank, a Maryland state-chartered bank and NW Bancorp’s wholly-owned subsidiary, merged with and into ACNB Bank, a Pennsylvania state-chartered bank and the Corporation’s wholly-owned subsidiary, with ACNB Bank as the surviving bank.

Subject to the terms and conditions of the Reorganization Agreement and at the election of the NW Bancorp stockholders, at the effective time of the merger, each share of NW Bancorp common stock was converted into the right to receive one of the following: (i) 1.10 shares of ACNB common stock or (ii) $30.00 in cash. Such election, however, was subject to allocation and proration procedures such that the number of shares of NW Bancorp common stock to be exchanged for Corporation common stock will be equal to 85% of the total number of shares of NW Bancorp common stock issued and outstanding at the effective time of the merger and the number of shares of NW Bancorp common stock to be exchanged for cash will be equal to 15% of the total number of shares of NW Bancorp common stock issued and outstanding at the effective time of the merger. As a result of NW Bancorp stockholder elections and the related allocation and proration provisions of the Reorganization Agreement, the Corporation issued approximately 950,000 shares of its common stock and approximately $4,520,000 in cash in the merger.

The foregoing description of the Reorganization Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Reorganization Agreement, which is attached hereto as Exhibit 2.1 and is incorporated herein by reference.
