Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions (see General Instruction A.2. below):

As of the opening of business on July 1, 2016 (the “Effective Time”), Lakeland Bancorp, Inc. (the “Company”) consummated its acquisition of Harmony Bank pursuant to the Agreement and Plan of Merger, dated as of February 17, 2016 (the “Merger Agreement”) by and among the Company, Lakeland Bank, the Company’s wholly-owned subsidiary, and Harmony Bank. At the Effective Time, Harmony Bank merged (the “Merger”) with and into Lakeland Bank, with Lakeland Bank continuing as the surviving entity.

Subject to the terms and conditions of the Merger Agreement, at the Effective Time, each share of Harmony Bank common stock issued and outstanding immediately prior to the Effective Time was converted into and became the right to receive 1.25 shares of the Company’s common stock. Cash will be paid in lieu of fractional shares. In the aggregate, the Company paid approximately 3,201,217 shares of the Company’s common stock in the Merger.

Former shareholders of Harmony Bank will be receiving Letters of Transmittal pursuant to which they may tender their Harmony Bank common stock certificates in exchange for their portion of the Merger consideration.

Pursuant to the terms of the Merger Agreement, all stock options to purchase Harmony Bank common stock outstanding at the Effective Time, which we refer to as “old stock options,” were forfeited or, if the holders executed and delivered prior to the Effective Time an option cancellation agreement, in form and substance reasonably satisfactory to the Company, cancelled in exchange for a payment by the Company equal to (x) the number of shares covered by the old stock option immediately prior to the Effective Time multiplied by (y) the amount, if any, by which the product of the closing price of the Company’s common stock on the date on which the Effective Time occurs multiplied by 1.25 exceeds the exercise price of such old stock option. The Company expects to pay approximately $868,532 in the aggregate in connection with the cancellation of the old stock options.

On July 1, 2016, the Company disseminated a press release announcing the closing of the Merger. A copy of the press release is attached as Exhibit 99.1 to this Current Report on Form 8-K.
