Item 8.01. Other Events.

Lakeland Bancorp, Inc. (the “Company”) has maintained the 2013 Lakeland Bancorp, Inc. Dividend Reinvestment and Stock Purchase Plan (the “Lakeland DRP”). American Stock Transfer & Trust Company LLC (“AST”), the administrator of the Lakeland DRP, has agreed to sponsor a dividend reinvestment and stock purchase plan for the Company’s common stock that mirrors in all material respects the Lakeland DRP (such AST plan, the “AST DRP”). The Company’s management and Board of Directors has concluded that the AST DRP would provide the Company’s shareholders with an alternative to the Lakeland DRP which would enable the Company’s shareholders to continue to reinvest the Company’s cash dividends in Lakeland common stock and invest through optional cash payments in shares of Lakeland common stock. Accordingly, the Company’s Board of Directors has terminated the Lakeland DRP effective April 27, 2014, so that AST may proceed with the AST DRP.

Shareholders will be receiving from AST detailed information concerning the AST DRP, which is sponsored by AST, and which will provide that those shareholders participating in the Lakeland DRP on April 27, 2014 will automatically become participants in the AST DRP, unless they notify AST that they do not wish to participate in the AST DRP. As a result of the transition by the Company’s shareholders from the Lakeland DRP to the AST DRP, no optional cash payments will be invested on May 1, 2014 (but may be invested on a monthly basis thereafter), and the Company’s second quarter cash dividend, which was declared on April 25, 2014 and is payable on May 15, 2014 to shareholders of record as of May 8, 2014, will be reinvested in shares of the Company’s common stock under the AST DRP on behalf of participants in the AST DRP.
