Exhibit 99.4

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

The following unaudited pro forma condensed combined financial information combines the historical consolidated financial position and results of operations of Provident Financial Services, Inc. (“Provident” or “Provident Financial”) and Lakeland Bancorp, Inc. (“Lakeland” or “Lakeland Bancorp”) as an acquisition of Lakeland by Provident. The Agreement and Plan of Merger (the “merger agreement”) was entered into on September 26, 2022, as amended, by and among Provident, Lakeland and NL 239 Corp., a direct, wholly owned subsidiary of Provident (“Merger Sub”), and provides that each share of Lakeland common stock issued and outstanding immediately prior to the effective time will be converted into the right to receive 0.8319 of a share of Provident common stock. The merger agreement provides that, upon the terms and subject to the conditions set forth therein, 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 (the “holdco merger”).

The unaudited pro forma condensed combined financial information has been prepared to give effect to the following:

• the acquisition of Lakeland by Provident under the provisions of the Financial Accounting Standards Board (FASB) Accounting Standards Codification, ASC 805, “Business Combinations” where the assets and liabilities of Lakeland will be recorded by Provident at their respective fair values as of the date the merger is completed;

• the distribution of shares of Provident common stock to Lakeland shareholders in exchange for shares of Provident common stock (based upon a 0.8319 exchange ratio);

• certain reclassifications to conform historical financial statement presentations of Lakeland to Provident; and

• transaction costs in connection with the merger.

The unaudited pro forma combined condensed consolidated financial information has been derived from and should be read in conjunction with: Provident’s audited consolidated financial statements and the related notes thereto as of and for the year ended December 31, 2023, which were included in Provident’s Annual Report on Form 10-K for the year ended December 31, 2023, and Provident’s unaudited financial statements and the related notes thereto as of and for the three months ended March 31, 2024, which were included in Provident’s Quarterly Report on Form 10-Q for the three months ended March 31, 2024, which were filed with the U.S. Securities and Exchange Commission (the “SEC”) on February 28, 2024, and April 26, 2024, respectively, and Lakeland’s audited consolidated financial statements as of and for the year ended December 31, 2023 and 2022 and Lakeland’s unaudited consolidated financial statements as of and for the three months ended March 31, 2024, which are being filed as Exhibit 99.2 and Exhibit 99.3 to this Current Report on Form 8-K, respectively.

The unaudited pro forma condensed combined income statements for the three months ended March 31, 2024 and for the year ended December 31, 2023 combine the historical consolidated income statements of Provident and Lakeland, giving effect to the merger as if it had been completed on January 1, 2023. The accompanying unaudited pro forma condensed combined balance sheet as of March 31, 2024 combines the historical consolidated balance sheets of Provident and Lakeland, giving effect to the merger as if it had been completed on March 31, 2024.

The unaudited pro forma condensed combined financial information is provided for illustrative information purposes only. The unaudited pro forma condensed combined financial information is not necessarily, and should not be assumed to be, an indication of the actual results that would have been achieved had the merger been completed as of the dates indicated or that may be achieved in the future. The unaudited pro forma condensed combined financial information has been prepared by Provident in accordance with Regulation S-X Article 11, Pro Forma Financial Information.

The unaudited pro forma condensed combined financial information also does not consider any potential effects of changes in market conditions on revenue enhancements, expense efficiencies, asset dispositions and share repurchases, among other factors. In addition, as explained in more detail in the accompanying notes, the preliminary allocation of the pro forma purchase price reflected in the unaudited pro forma condensed combined financial information is subject to adjustment and may vary significantly from the actual purchase price allocation that will be recorded upon completion of the merger.

As of the date of this Current Report on Form 8-K, Provident has not completed the valuation analysis and calculations in sufficient detail necessary to arrive at the required estimates of the fair value of Lakeland’s assets to be acquired or liabilities to be assumed, other than a preliminary estimate for intangible assets and certain financial assets and financial liabilities. Accordingly, apart from the aforementioned, certain Lakeland assets and liabilities are presented at their respective carrying amounts and should be treated as preliminary values. A final determination of the fair value of Lakeland’s assets and liabilities will be based on Lakeland’s actual assets and liabilities as of the closing date and therefore cannot be made prior to the completion of the merger. In addition, the value of the merger consideration to be paid by Provident in shares of Provident common stock upon the completion of the merger will be determined based on the closing price of Provident common stock on the closing date of the merger and the number of issued and outstanding shares of Lakeland common stock immediately prior to the closing of the merger. Actual adjustments may differ from the amounts reflected in the unaudited pro forma condensed combined financial information, and the differences may be material.

Further, Provident has not identified all adjustments necessary to conform Lakeland’s accounting policies to Provident’s accounting policies. Upon completion of the merger, or as more information becomes available, Provident will perform a more detailed review of Lakeland’s accounting policies. As a result of that review, differences could be identified between the accounting policies of the two companies that, when conformed, could have a material impact on the combined company’s financial information.

As a result of the foregoing, the pro forma adjustments are preliminary and are subject to change as additional information becomes available and as additional analysis is performed. The preliminary pro forma adjustments have been made solely for the purpose of providing the unaudited pro forma condensed combined financial information.

Provident estimated the fair value of certain Lakeland assets and liabilities based on a preliminary valuation analysis, due diligence information, information presented in Lakeland’s SEC filings and other publicly available information. Until the merger is completed, both companies are limited in their ability to share certain information.

Upon completion of the merger, a final determination of the fair value of Lakeland’s assets acquired and liabilities assumed will be performed. Any changes in the fair values of the net assets or total purchase consideration as compared with the information shown in the unaudited pro forma condensed combined financial information may change the amount of the total purchase consideration allocated to goodwill and other assets and liabilities and may impact the combined company’s statement of income. The final purchase consideration allocation may be materially different than the preliminary purchase consideration allocation presented in the unaudited pro forma condensed combined financial information.

Note—Basis of Presentation

The unaudited pro forma condensed combined financial information and explanatory notes have been prepared to illustrate the effects of the merger under the acquisition method of accounting with Provident as the acquirer. The unaudited pro forma condensed combined financial information is presented for illustrative purposes only and does not necessarily indicate the financial condition or results of operations of the combined company had the companies been combined at the beginning of each period presented, nor does it necessarily indicate the results of operations in future periods or the future financial position of the combined company. Under the acquisition method of accounting, the assets and liabilities of Lakeland, as of the effective time, will be recorded by Provident at their respective fair values and the excess of the merger consideration over the fair value of Lakeland’s net assets will be allocated to goodwill.

The merger provides for Lakeland shareholders to receive 0.8319 of a share of Provident common stock, valuing the transaction at approximately $1.3 billion based on the closing share price of Provident common stock of $23.16 as of September 26, 2022.

The pro forma allocation of the purchase price reflected in the unaudited pro forma condensed combined financial information is subject to adjustment and may vary from the actual purchase price allocation that will be recorded at the time the merger is completed. Adjustments may include, but not be limited to, changes in (i) Lakeland’s balance sheet through the effective time; (ii) the aggregate value of merger consideration paid if the price of shares of Provident common stock varies from the assumed $23.16 per share, which represents the closing share price of Provident common stock on September 26, 2022; (iii) total merger-related expenses if consummation and/or implementation costs vary from currently estimated amounts; and (iv) the underlying values of assets and liabilities if market and credit conditions differ from current assumptions.
