As previously disclosed, on September 26, 2022, Provident Financial Services, Inc., a Delaware corporation (“Provident”), NL 239 Corp., a Delaware corporation and a direct, wholly owned subsidiary of Provident (“Merger Sub”), and Lakeland Bancorp, Inc., a New Jersey corporation (“Lakeland”), entered into an Agreement and Plan of Merger (the “Merger Agreement”). Pursuant to the terms and subject to the conditions set forth in the Merger Agreement, Merger Sub will merge with and into Lakeland, with Lakeland as the surviving entity (the “Merger”), and as soon as reasonably practicable following the Merger, Lakeland will merge with and into Provident, with Provident as the surviving entity.

In connection with the proposed Merger, Provident filed with the Securities and Exchange Commission (the “SEC”) a registration statement on Form S-4 containing a joint proxy statement/prospectus, as amended, and Provident filed a definitive proxy statement/prospectus and Lakeland filed a definitive proxy statement with the SEC, each dated December 21, 2022 (collectively, the “joint proxy statement/prospectus”), which Provident first mailed to its stockholders and Lakeland first mailed to its shareholders on or about December 22, 2022.

Following the announcement of the Merger Agreement, as of the date of this Current Report on Form 8-K, seven lawsuits and six demand letters challenging the disclosures contained in the joint proxy statement/prospectus or other aspects of the Merger have been filed. The first lawsuit, captioned Shiva Stein v. Lakeland Bancorp, Inc. et al., Case No. 1:22-cv-09946, was filed in the U.S. District Court for the Southern District of New York on November 22, 2022. The second lawsuit, captioned Ryan O’Dell v. Lakeland Bancorp, Inc. et al., Case No. 1:22-cv-09980, was filed in the U.S. District Court for the Southern District of New York on November 23, 2022. The third lawsuit, captioned Stephen Bushansky v. Lakeland Bancorp, Inc. et al., Case No. 2:22-cv-07131, was filed in the U.S. District Court for the District of New Jersey on December 7, 2022. The fourth lawsuit, captioned Molly Kaplan v. Lakeland Bancorp, Inc. et al., Case No. 2:22-cv- 07193, was filed in the U.S. District Court for the District of New Jersey on December 8, 2022. The fifth lawsuit, captioned Michael Rubin v. Provident Financial Services, Inc. et al., Case No. 1:22-cv-10485, was filed in the U.S. District Court for the Southern District of New York on December 12, 2022. The sixth lawsuit, captioned Paul Berger Revocable Trust v. Provident Financial Services, Inc. et al., Docket No. HUD-C-000005-23, was filed in the Superior Court of New Jersey on January 4, 2023. The seventh lawsuit, captioned Charles Reinhardt v. Lakeland Bancorp, Inc. et al., Case No. 1:23-cv-00113, was filed in the U.S. District Court for the Southern District of New York on January 6, 2023. The complaints in the Stein, O’Dell, Bushansky, Kaplan and Reinhardt actions are brought by alleged Lakeland shareholders and assert claims against Lakeland and the members of its board of directors. The complaints in the Rubin and Berger actions are brought by alleged Provident stockholders and assert claims against Provident and the members of its board of directors. The complaints filed in the actions, other than the Berger action, allege, among other things, that the defendants caused a materially incomplete and misleading registration statement relating to the proposed Merger to be filed with the SEC in violation of Section 14(a) and Section 20(a) of the Securities Exchange Act of 1934, as amended, and Rule 14a-9 promulgated thereunder. In addition, the complaint in the Berger action alleges that certain directors of Provident breached fiduciary duties of good faith, loyalty, fair dealing, due care and disclosure under Delaware law. On January 17, 2023, the plaintiff in the Berger action filed a motion seeking an interlocutory injunction that would, among other things, enjoin the closing of the vote at the special meeting of Provident’s stockholders, to be held virtually via the internet on February 1, 2023, in connection with the Merger. The court has not ruled on this motion. We refer to the foregoing lawsuits and demand letters collectively as the “Merger Actions.”

Provident and Lakeland believe that the claims asserted in the Merger Actions referred to above are without merit and supplemental disclosures are not required or necessary under applicable laws. However, in order to diminish the risk that these Merger Actions delay or otherwise adversely affect the Merger, and to minimize the costs, risks and uncertainties inherent in defending the Merger Actions, and without admitting any liability or wrongdoing, Provident and Lakeland have determined to supplement the joint proxy statement/prospectus as described in this Current Report on Form 8-K. Provident, Lakeland and the other named defendants deny that they have violated any laws or breached any duties to Provident’s stockholders or Lakeland’s shareholders, as applicable. Nothing in this Current Report on Form 8-K shall be deemed an admission of the legal necessity or materiality under applicable laws of any of the disclosures set forth herein. To the contrary, Provident and Lakeland specifically deny all allegations in the Merger Actions that any additional disclosure was or is required.

Forward-Looking Statements

This Current Report on Form 8-K includes “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995, Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, with respect to Provident’s and Lakeland’s beliefs, goals, intentions, and expectations regarding the proposed transaction, revenues, earnings, earnings per share, loan production, asset quality, and capital levels, among other matters; our estimates of future costs and benefits of the actions we may take; our assessments of probable losses on loans; our assessments of interest rate and other market risks; our ability to achieve our financial and other strategic goals; the expected timing of completion of the proposed transaction; the expected cost savings, synergies and other anticipated benefits from the proposed transaction; and other statements that are not historical facts.

Forward-looking statements are typically identified by such words as “believe,” “expect,” “anticipate,” “intend,” “outlook,” “estimate,” “forecast,” “project,” “should,” and other similar words and expressions, and are subject to numerous assumptions, risks, and uncertainties, which change over time. These forward-looking statements include, without limitation, those relating to the terms, timing and closing of the proposed transaction.

Additionally, forward-looking statements speak only as of the date they are made; Provident and Lakeland do not assume any duty, and do not undertake, to update such forward-looking statements, whether written or oral, that may be made from time to time, whether as a result of new information, future events, or otherwise. Furthermore, because forward-looking statements are subject to assumptions and uncertainties, actual results or future events could differ, possibly materially, from those indicated in such forward-looking statements as a result of a variety of factors, many of which are beyond the control of Provident and Lakeland. Such statements are based upon the current beliefs and expectations of the management of Provident and Lakeland and are subject to significant risks and uncertainties outside of the control of the parties. Caution should be exercised against placing undue reliance on forward-looking statements. The factors that could cause actual results to differ materially include the following: the occurrence of any event, change or other circumstances that could give rise to the right of one or both of the parties to terminate the Merger Agreement; the outcome of any legal proceedings that may be instituted against Provident or Lakeland; the possibility that the proposed transaction will not close when expected or at all because required regulatory, shareholder or other approvals are not received or other conditions to the closing are not satisfied on a timely basis or at all, or are obtained subject to conditions that are not anticipated (and the risk that required regulatory approvals may result in the imposition of conditions that could adversely affect the combined company or the expected benefits of the proposed transaction); the ability of Provident and Lakeland to meet expectations regarding the timing, completion and accounting and tax treatments of the proposed transaction; the risk that any announcements relating to the proposed transaction could have adverse effects on the market price of the common stock of either or both parties to the proposed transaction; the possibility that the anticipated benefits of the proposed transaction will not be realized when expected or at all, including as a result of the impact of, or problems arising from, the integration of the two companies or as a result of the strength of the economy and competitive factors in the areas where Provident and Lakeland do business; certain restrictions during the pendency of the proposed transaction that may impact the parties’ ability to pursue certain business opportunities or strategic transactions; the possibility that the transaction may be more expensive to complete than anticipated, including as a result of unexpected factors or events; diversion of management’s attention from ongoing business operations and opportunities; the possibility that the parties may be unable to achieve expected synergies and operating efficiencies in the merger within the expected timeframes or at all and to successfully integrate Lakeland’s operations and those of Provident; such integration may be more difficult, time consuming or costly than expected; revenues following the proposed transaction may be lower than expected; Provident’s and Lakeland’s success in executing their respective business plans and strategies and managing the risks involved in the foregoing; the dilution caused by Provident’s issuance of additional shares of its capital stock in connection with the proposed transaction; effects of the announcement, pendency or completion of the proposed transaction on the ability of Provident and Lakeland to retain customers and retain and hire key personnel and maintain relationships with their suppliers, and on their operating results and businesses generally; and risks related to the potential impact of general economic, political and market factors on the companies or the proposed transaction and other factors that may affect future results of Provident and Lakeland; uncertainty as to the extent of the duration, scope, and impacts of the COVID-19 pandemic on Provident, Lakeland and the proposed transaction; and the other factors discussed in the “Risk Factors” section of each of Provident’s and Lakeland’s Annual Report on Form 10-K for the year ended December 31, 2021, in the “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” sections of each of Provident’s and Lakeland’s Quarterly Report on Form 10-Q for the quarter ended September 30, 2022, and other reports Provident and Lakeland file with the SEC.
