Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies A. Basis of Financial Statement Presentation The accompanying unaudited consolidated financial statements include the accounts of Provident Financial Services, Inc. (the "Company") and its wholly owned subsidiary, Provident Bank (the “Bank") and its wholly owned subsidiaries. In preparing the interim unaudited consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the consolidated statements of financial condition and the consolidated statements of income for the periods presented. Actual results could differ from these estimates. The allowance for credit losses is a material estimate that is particularly susceptible to near-term change. The interim unaudited consolidated financial statements reflect all normal and recurring adjustments, which are, in the opinion of management, considered necessary for a fair presentation of the financial condition and results of operations for the periods presented. The results of operations for the three and six months ended June 30, 2024 are not necessarily indicative of the results of operations that may be expected for all of 2024. Certain information and note disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission. Additionally, certain comparative balances on the interim unaudited consolidated financial statements have been reclassified to conform to the current year’s presentation. These unaudited consolidated financial statements should be read in conjunction with the December 31, 2023 Annual Report to Stockholders on Form 10-K. B. Earnings Per Share The following is a reconciliation of the numerators and denominators of the basic and diluted earnings per share calculations for the three and six months ended June 30, 2024 and 2023 (dollars in thousands, except per share amounts): Three months ended June 30, 2024 2023 Net Weighted Per Net Weighted Per Net (loss) income $ (11,485) $ 32,003 Basic earnings per share: (Loss) Income available to common stockholders $ (11,485) 102,957,521 $ (0.11) $ 32,003 74,823,272 $ 0.43 Dilutive shares — 6,915 Diluted earnings per share: (Loss) Income available to common stockholders $ (11,485) 102,957,521 $ (0.11) $ 32,003 74,830,187 $ 0.43 Six months ended June 30, 2024 2023 Net Weighted Per Net Weighted Per Net income $ 20,596 $ 72,539 Basic earnings per share: Income available to common stockholders $ 20,596 89,108,775 $ 0.23 $ 72,539 74,734,795 $ 0.97 Dilutive shares 7,815 32,053 Diluted earnings per share: Income available to common stockholders $ 20,596 89,116,590 $ 0.23 $ 72,539 74,766,848 $ 0.97 Anti-dilutive stock options and awards as of June 30, 2024 and 2023, totaling 1.5 million shares and 1.3 million shares, respectively, were excluded from the earnings per share calculations. C. Loans Receivable and Allowance for Credit Losses The impact of utilizing the current expected credit loss ("CECL") methodology approach to calculate the allowance for credit losses on loans is significantly influenced by the composition, characteristics and quality of the Company’s loan portfolio, as well as the prevailing economic conditions and forecast utilized. Material changes to these and other relevant factors may result in greater volatility to the allowance for credit losses, and therefore, greater volatility to the Company’s reported earnings. For the three and six months ended June 30, 2024, an initial CECL provision for credit losses on loans and commitments to extend credit of $65.2 million was recorded as part of the Lakeland merger in accordance with GAAP requirements for accounting for business combinations. See Notes 4 and 10 to the Consolidated Financial Statements for more information on the allowance for credit losses on loans and off-balance sheet credit exposures. D. Goodwill Goodwill represents the excess of the purchase price over the estimated fair value of identifiable net assets acquired through purchase acquisitions. Goodwill with an indefinite useful life is not amortized, but is evaluated for impairment on an annual basis, or more frequently if events or changes in circumstances indicate potential impairment between annual measurement dates. Goodwill is analyzed for impairment at least once a year. The Company prepares a qualitative assessment in determining whether goodwill may be impaired. The factors considered in the assessment include macroeconomic conditions, industry and market conditions and overall financial performance of the Company, among others. The Company completed its most recent annual goodwill impairment test as of July 1, 2024. The Company performed a qualitative analysis of goodwill and concluded that no triggering events were identified and therefore a test for impairment between annual tests was not required. Accounting Pronouncements Not Yet Adopted In December 2023, FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures”. The amendments in this ASU require improved annual income tax disclosures surrounding rate reconciliation, income taxes paid, and other disclosures. This update will be effective for financial statements issued for fiscal years beginning after December 15, 2024, with early adoption in the interim period permitted. The Company is currently evaluating the impact of this standard on the consolidated financial statements.

Business Combination, Asset Acquisition, and Joint Venture Formation [Abstract]
Business Combinations	Business Combinations Lakeland Bancorp, Inc. - Merger Agreement On May 16, 2024, the Company completed its merger with Lakeland Bancorp, Inc. ("Lakeland"), which added $10.91 billion to total assets, $7.91 billion to total loans, $8.62 billion to total deposits and 68 full-service banking offices in New Jersey and New York. The Company expects to close 13 of the acquired Lakeland banking offices and nine legacy Bank branches in the third quarter of 2024 due to geographic overlap. Under the merger agreement, each share of Lakeland common stock was converted into the right to receive 0.8319 shares of the Company's common stock, a total of 54,356,954 shares converted, plus cash in lieu of fractional shares. The total consideration paid for the acquisition of Lakeland was $876.8 million. In connection with the acquisition, Lakeland Bank, a wholly owned subsidiary of Lakeland, was merged with and into the Bank. The acquisition was accounted for under the acquisition method of accounting. Under this method of accounting, the purchase price has been allocated to the respective assets acquired and liabilities assumed based upon their estimated fair values, net of tax. The excess of consideration paid over the estimated fair value of the net assets acquired totaled $190.9 million and was recorded as goodwill. The following table summarizes the estimated fair values of the assets acquired and the liabilities assumed at the merger date, net of cash consideration paid (in thousands): As of May 16, 2024 Assets acquired: Cash and cash equivalents, net $ 194,548 Available for sale debt securities 1,585,993 Federal Home Loan Bank stock 46,113 Loans held for sale 1,494 Loans held for investment 7,906,326 Allowance for credit losses on PCD loans (17,188) Loans, net 7,889,138 Bank-owned life insurance 160,646 Banking premises and equipment 60,578 Accrued interest receivable 27,241 Goodwill 190,858 Other intangibles assets 209,915 Other assets 242,011 Total assets acquired $ 10,608,535 Liabilities assumed: Deposits 8,622,924 Mortgage escrow deposits 5,532 Borrowed funds 785,927 Subordinated debentures 180,198 Other liabilities 137,176 Total liabilities assumed $ 9,731,757 Net assets acquired $ 876,778 The calculation of goodwill is subject to change for up to one year after the date of acquisition as additional information relative to the closing date estimates and uncertainties become available. As the Company finalizes its review of the acquired assets and liabilities, certain adjustments to the recorded carrying values and goodwill may be required. Fair Value Measurement of Assets Assumed and Liabilities Assumed The methods used to determine the fair value of the assets acquired and liabilities assumed in the Lakeland acquisition were as follows: Securities Available for Sale The estimated fair values of the available for sale debt securities, primarily comprised of U.S. government agency mortgage-backed securities and U.S. government agency and municipal bonds carried on Lakeland's balance sheet was confirmed using open market pricing provided by multiple independent securities brokers. Management reviewed the open market quotes used in pricing the securities and a fair value adjustment was not recorded on the investments. A fair value discount of $249.7 million was recorded on the investments. Loans Loans acquired from Lakeland were recorded at fair value, and there was no carryover related allowance for loan and lease losses. The fair values of loans acquired from Lakeland were estimated using the discounted cash flow method based on the remaining maturity and repricing terms. Cash flows were adjusted for expected losses and prepayments. Projected cash flows were then discounted to present value based on: the relative risk of the cash flows, taking into account the loan type, liquidity risk, the maturity of the loans, servicing costs, and a required return on capital; and monthly principal and interest cash flows were discounted to present value and summed to arrive at the calculated value of the loans. The fair value of the acquired loans receivable had a gross amortized cost basis of $7.91 billion. For loans acquired without evidence of more-than-insignificant deterioration in credit quality since origination, the Company recorded interest rate loan fair value and credit fair value adjustments. Loans were grouped into pools based on similar characteristics, such as loan type, fixed or adjustable interest rates, payment type, index rate and caps/floors, and non-accrual status. The loans were valued at the sub-pool level and were pooled at the summary level based on loan type. Market rates for similar loans were obtained from various internal and external data sources and reviewed by management for reasonableness. The average of these market rates was used as the fair value interest rate that a market participant would utilize. A present value approach was utilized to calculate the interest rate fair value discount of $297.2 million. The Company used historical annual average charge-off percentages for banking institutions identified as peers of the Company and Lakeland combined as a market-participant proxy to develop the life-of-loan loss rates per loan type for the Non-PCD loans. The default and loss rates were then applied to the principal balance to arrive at the projected credit losses for each period, which resulted in a credit fair value discount of $82.4 million. Loans acquired that have experienced more-than-insignificant deterioration in credit quality since origination are considered purchased credit deteriorated (“PCD”) loans. The Company evaluated acquired loans for deterioration in credit quality based on any of, but not limited to, the following: (1) non-accrual status; (2) modifications for borrowers experiencing financial difficulty; (3) risk ratings of watch, special mention, substandard or doubtful; and (4) loans greater than 59 days past due. At the acquisition date, an estimate of expected credit losses was made for groups of PCD loans with similar risk characteristics and individual PCD loans without similar risk characteristics. This estimate of credit losses was calculated using management's best estimate of projected losses over the remaining life of the loans. This represents the portion of the loan balances that has been deemed uncollectible based on the Company’s expectations of future cash flows for each respective PCD loan pool, given the outlook and forecasts. The expected lifetime losses were calculated using historical losses observed at the Bank, Lakeland and peer banks. A $17.2 million allowance for credit losses was recorded on PCD loans. The interest rate fair value adjustment related to PCD loans will be substantially recognized as interest income on a level yield amortization or straight line method over the expected life of the loans. The table below illustrates the fair value adjustments made to the amortized cost basis in order to present the fair value of the loans acquired (in thousands): Gross amortized cost basis as of May 16, 2024 $ 8,323,589 Interest rate fair value adjustment on all loans (330,540) Credit fair value adjustment on non-PCD loans (82,359) Charge-offs on PCD Loans at acquisition (4,364) Allowance for credit losses on PCD loans (17,188) Fair value of acquired loans, net, as of May 16, 2024 $ 7,889,138 The table below is a summary of the PCD loans that were acquired from Lakeland as of the closing date (in thousands): Gross amortized cost basis as of May 16, 2024 $ 564,147 Charge-offs on PCD Loans at acquisition (4,364) Interest component of expected cash flows (accretable difference) (33,365) Allowance for credit losses on PCD loans (17,188) Net PCD loans $ 509,230 Banking Premises and Equipment The Company acquired 68 branches from Lakeland, 29 of which were owned premises. The Company expects to close 13 of the acquired banking offices in the third quarter of 2024. The fair value of Lakeland’s premises was determined based upon independent third-party appraisals performed by licensed appraisers in the market in which the premises are located. Core Deposit Intangible The fair value of the core deposit intangible was measured using a discounted cash flow approach by comparing the all-in cost of less rate sensitive deposits against an alternative funding source. The discounted cash flow approach is used because there is no reliable market participant data to support a market approach nor is there an effective measure to utilize the cost approach. To calculate the value of core deposits, deposit account servicing costs (net of deposit fee income) and interest expense on deposits were compared to the cost of alternative funding sources by using an average of Federal Home Loan Bank of New York ("FHLBNY") advance rates and brokered CD rates as disclosed by market sources. The projected cash flows were developed using projected deposit attrition rates. The discount rate was calculated using the Capital Assets Pricing Model. The core deposit intangible totaled $209.2 million and is being amortized over its estimated life of approximately 10 years based on dollar weighted deposit runoff on an annualized basis. The core deposit intangible will be evaluated annually for impairment. Bank Owned Life Insurance ("BOLI") Lakeland's BOLI cash surrender value was $160.6 million with no fair value adjustment required. Time Deposits The fair value adjustment for time deposits represents a discount from the value of the contractual repayments of fixed-maturity deposits using prevailing market interest rates for similar-term time deposits. The time deposit discount of approximately $1.2 million is being amortized into income on a level yield basis over the contractual life of the deposits. Borrowings The fair value of FHLBNY advances was determined based on a discounted cash flow analysis using a discount rate derived from FHLBNY rates as of May 16, 2024. The cash flows of the advances were projected based on the scheduled payments of each advance. Subordinated Debentures At the valuation date, Lakeland had three outstanding trust preferred issuances and a subordinated debt issuance with an aggregate balance of $180.2 million, all of which was assumed by the Company on May 16, 2024 . The fair value of trust preferred and subordinated debt issuances was determined based on a discounted cash flow analysis using a discount rate commensurate with yields and terms of comparable issuances. The cash flows were projected through the remaining contractual term of the trust preferred issuance and based on the call date for the subordinated debt issuance. Merger-Related Expenses Merger-related expenses, which is a separate line in non-interest expense on the Consolidated Statements of Income, totaled $18.9 million and $21.1 million for the three and six months ended June 30, 2024, respectively, compared with $2.0 million and $3.1 million for the three and six months ended June 30, 2023.

Management measures expected credit losses on held to maturity debt securities on a collective basis by security type. Management classifies the held to maturity debt securities portfolio into the following security types: • Government-agency obligations; • Mortgage-backed securities; • State and municipal obligations; and • Corporate obligations. All of the agency obligations held by the Company are issued by U.S. government entities and agencies. These securities are either explicitly or implicitly guaranteed by the U.S. government, are highly rated by major rating agencies and have a long history of no credit losses. The majority of the state and municipal and corporate obligations carry credit ratings from the rating agencies as of June 30, 2024 that were no lower than an A rating and the Company had no securities rated BBB or worse by Moody’s Ratings ("Moody's").

The increases in provision for both periods was primarily attributable to an initial CECL provision for credit losses on loans of $60.1 million recorded as part of the Lakeland merger in accordance with GAAP requirements for accounting for business combinations. For the three months ended June 30, 2024, net charge-offs totaled $1.3 million, which was primarily attributable to one commercial loan. For the six months ended June 30, 2024, net charge-offs totaled $2.3 million, which was primarily attributable to two commercial loans.

The Company defines a loan individually evaluated for impairment as a non-homogeneous loan greater than $1.0 million, for which, based on current information, it is not expected to collect all amounts due under the contractual terms of the loan agreement. As of June 30, 2024, there were 18 loans totaling $54.6 million, compared to 17 loans totaling $42.3 million as of December 31, 2023, that were individually evaluated for impairment. A financial asset is considered collateral-dependent when the debtor is experiencing financial difficulty and repayment is expected to be provided substantially through the sale or operation of the collateral. For all classes of loans deemed collateral-dependent, the Company estimates expected credit losses based on the collateral’s fair value less any selling costs. A specific allocation of the allowance for credit losses is established for each collateral-dependent loan with a carrying balance greater than the collateral’s fair value, less estimated selling costs. In most cases, the Company records a partial charge-off to reduce the loan’s carrying value to the collateral’s fair value less estimated selling costs. The Company uses third-party appraisals to determine the fair value of the underlying collateral in its analysis of collateral-dependent loans. A third-party appraisal is generally ordered as soon as a loan is designated as a collateral-dependent loan and updated annually, or more frequently if required. At each fiscal quarter end, if a loan is designated as collateral-dependent and the third-party appraisal has not yet been received, an evaluation of all available collateral is made using the best information available at the time, including rent rolls, borrower financial statements and tax returns, prior appraisals, management’s knowledge of the market and collateral, and internally prepared collateral valuations based upon market assumptions regarding vacancy and capitalization rates, each as and where applicable. Once the appraisal is received and reviewed, the specific reserves are adjusted to reflect the appraised value and evaluated for charge offs. The Company believes there have not been any significant time lapses since the receipt of the most recent appraisals. As of June 30, 2024 and December 31, 2023, the Company had collateral-dependent loans with fair values of $18.4 million and $24.1 million secured by commercial real estate, respectively. Loan modifications to borrowers experiencing financial difficulty may include interest rate reductions, principal or interest forgiveness, forbearance, term extensions, and other actions intended to minimize economic loss and to avoid foreclosure or repossession of collateral. In addition, management attempts to obtain additional collateral or guarantor support when modifying such loans. If the borrower has demonstrated performance under the previous terms and our underwriting process shows the borrower has the capacity to continue to perform under the restructured terms, the loan will continue to accrue interest. Non-accruing restructured loans may be returned to accrual status when there has been a sustained period of repayment performance (generally six consecutive months of payments) and both principal and interest are deemed collectible. The following illustrates the most common loan modifications by loan classes offered by the Company that are required to be disclosed pursuant to the requirements of ASU 2022-02: Loan Classes Modification types Commercial Term extension, interest rate reductions, payment delay, or combination thereof. These modifications extend the term of the loan, lower the payment amount, or otherwise delay payments during a defined period for the purpose of providing borrowers additional time to return to compliance with the original loan term. Residential Mortgage/ Home Equity Forbearance period greater than six months. These modifications require reduced or no payments during the forbearance period for the purpose of providing borrowers additional time to return to compliance with the original loan term as well as term extension and rate adjustment. These modifications extend the term of the loan and provides for an adjustment to the interest rate, which reduces the monthly payment requirement. Direct Installment Term extension greater than three months. These modifications extend the term of the loan, which reduces the monthly payment requirement. In 2023, the Company adopted ASU 2022-02, “Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures” (“ASU 2022-02”), which eliminated the accounting guidance for troubled debt restructurings while enhancing disclosure requirements for certain loan refinancing and restructurings by creditors when a borrower is experiencing financial difficulty. This guidance was applied on a modified retrospective basis. Upon adoption of this guidance, the Company no longer establishes a specific reserve for loan modifications to borrowers experiencing financial difficulty. Instead, these loan modifications are included in their respective pool and a projected loss rate is applied to the current loan balance to arrive at the quantitative and qualitative baseline portion of the allowance for credit losses. At adoption, the Company recorded a $594,000 reduction to the allowance for credit losses, which resulted in a $433,000 cumulative effect adjustment increase, net of tax, to retained earnings.

As of June 30, 2024, the balance of PCD loans totaled $697.9 million with a related allowance for credit losses of $16.4 million. The balance of PCD loans as of December 31, 2023 was $165.1 million with a related allowance for credit losses of $1.7 million. In connection with the Lakeland merger, the Company evaluated acquired loans for deterioration in credit quality based on any of, but not limited to, the following: (1) non-accrual status; (2) modifications for borrowers experiencing financial difficulty; (3) risk ratings of watch, special mention, substandard or doubtful; and (4) loans greater than 59 days past due. At the acquisition date, an estimate of expected credit losses is made for groups of PCD loans with similar risk characteristics and individual PCD loans without similar risk characteristics. Additionally for PCD loans, an allowance for credit losses was calculated using management's best estimate of projected losses over the remaining life of the loans. This represents the portion of the loan balances that has been deemed uncollectible based on the Company’s expectations of future cash flows for each respective PCD loan pool, given the outlook and forecasts inclusive of related fiscal and regulatory interventions. The expected lifetime losses were calculated using historical losses observed at the Bank, Lakeland and peer banks. A $17.2 million allowance for credit losses was recorded on PCD loans acquired from Lakeland. The interest rate fair value adjustment related to PCD loans will be substantially recognized as interest income on a level yield or straight line method over the expected life of the loans. The table below is a summary of the PCD loans that were acquired from Lakeland as of the closing date (in thousands): Gross amortized cost basis as of May 16, 2024 $ 564,147 Charge-offs on PCD Loans at acquisition (4,364) Interest component of expected cash flows (accretable difference) (33,365) Allowance for credit losses on PCD loans (17,188) Net PCD loans $ 509,230 Management utilizes an internal nine-point risk rating system to summarize its loan portfolio into categories with similar risk characteristics. Loans deemed to be “acceptable quality” are rated 1 through 4, with a rating of 1 established for loans with minimal risk. Loans that are deemed to be of “questionable quality” are rated 5 (watch) or 6 (special mention). Loans with adverse classifications (substandard, doubtful or loss) are rated 7, 8 or 9, respectively. Commercial mortgage, commercial, multi-family and construction loans are rated individually, and each lending officer is responsible for risk rating loans in their portfolio. These risk ratings are then reviewed by the department manager and/or the Chief Lending Officer and by the Credit Department. The risk ratings are also reviewed periodically through loan review examinations which are currently performed by independent third-parties.

Commitments and Contingencies Disclosure [Abstract]
Contingencies	Contingencies The Company is involved in various litigation and claims arising in the normal course of business. On May 2, 2022, a purported class action complaint was filed against the Bank in the Superior Court of New Jersey, which alleges that the Bank wrongfully assessed overdraft fees related to debit card transactions. The complaint asserted claims for breach of contract and breach of the covenant of good faith and fair dealing as well as an alleged violation of the New Jersey Consumer Fraud Act. Plaintiff sought to represent a proposed class of all the Bank's checking account customers who were charged overdraft fees on transactions that were authorized into a positive available balance. The parties mediated the matter on May 28, 2024, and agreed in principle to a settlement resolving the dispute with the Bank contributing $1.85 million to a settlement fund. The motion for preliminary approval is due to the Court on September 6, 2024.

Credit Loss [Abstract]
Allowance for Credit Losses on Off-Balance Sheet Credit Exposures	Allowance for Credit Losses on Off-Balance Sheet Credit Exposures Management analyzes the Company's exposure to credit losses for both on-balance sheet and off-balance sheet activity using a consistent methodology for the quantitative framework as well as the qualitative framework. For purposes of estimating the allowance for credit losses for off-balance sheet credit exposures, the exposure that may default includes an estimated drawdown of unused credit based on historical credit utilization factors and current loss factors. For the three and six months ended June 30, 2024, the Company recorded a $3.7 million and a $3.1 million provision charge for credit losses for off-balance sheet credit exposures, respectively. For the three and six months ended June 30, 2023, the Company recorded a $647,000 provision benefit for credit losses for off-balance sheet credit exposures and a $92,000 provision charge for credit losses for off-balance sheet credit exposures, respectively. The $4.3 million increase and the $3.1 million increase in the provision for the three and six months ended June 30, 2024, compared to the same period in 2023, primarily related to the establishment of an allowance for credit losses on commitments to extend credit acquired from Lakeland. The allowance for credit losses for off-balance sheet credit exposures was $6.6 million as of June 30, 2024 and $3.4 million as of December 31, 2023, and are included in other liabilities on the Consolidated Statements of Financial Condition.

Fair Value Measurements

Fair Value Measurements	6 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The Company utilizes fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. The determination of fair values of financial instruments often requires the use of estimates. Where quoted market values in an active market are not readily available, management utilizes various valuation techniques to estimate fair value. Fair value is an estimate of the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. However, in many instances fair value estimates may not be substantiated by comparison to independent markets and may not be realized in an immediate sale of the financial instrument. GAAP establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are as follows: Level 1: Unadjusted quoted market prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities; Level 2: Quoted prices in markets that are not active, or inputs that are observable either directly or indirectly, for substantially the full term of the asset or liability; and Level 3: Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity). A financial instrument’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. The valuation techniques are based upon the unpaid principal balance only, and exclude any accrued interest or dividends at the measurement date. Interest income and expense and dividend income are recorded within the consolidated statements of income depending on the nature of the instrument using the effective interest method based on acquired discount or premium. Assets and Liabilities Measured at Fair Value on a Recurring Basis The valuation techniques described below were used to measure fair value of financial instruments in the table below on a recurring basis as of June 30, 2024 and December 31, 2023. Available for Sale Debt Securities, at Fair Value For available for sale debt securities, fair value was estimated using a market approach. The majority of the Company’s securities are fixed income instruments that are not quoted on an exchange, but are traded in active markets. Prices for these instruments are obtained through third-party data service providers or dealer market participants with whom the Company has historically transacted both purchases and sales of securities. Prices obtained from these sources include market quotations and matrix pricing. Matrix pricing, a Level 2 input, is a mathematical technique used principally to value certain securities by benchmarking to comparable securities. The Company evaluates the quality of Level 2 matrix pricing through comparison to similar assets with greater liquidity and evaluation of projected cash flows. As management is responsible for the determination of fair value, it performs quarterly analyses on the prices received from the pricing service to determine whether the prices are reasonable estimates of fair value. Specifically, management compares the prices received from the pricing service to a secondary pricing source. Additionally, management compares changes in the reported market values and returns to relevant market indices to test the reasonableness of the reported prices. The Company’s internal price verification procedures and review of fair value methodology documentation provided by independent pricing services has generally not resulted in an adjustment in the prices obtained from the pricing service. The Company also holds debt instruments issued by the U.S. government that are traded in active markets with readily accessible quoted market prices that are considered Level 1 within the fair value hierarchy. Equity Securities at Fair Value The Company holds equity securities that are traded in active markets with readily accessible quoted market prices that are considered Level 1 inputs. Derivatives The Company records all derivatives on the statements of financial condition at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. The Company has interest rate derivatives resulting from a service provided to certain qualified borrowers in a loan related transaction which, therefore, are not used to manage interest rate risk in the Company’s assets or liabilities. As such, all changes in fair value of these derivatives are recognized directly in earnings. The Company also uses interest rate swaps as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges, and which satisfy hedge accounting requirements, involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without the exchange of the underlying notional amount. These derivatives were used to hedge the variable cash outflows associated with FHLBNY borrowings and brokered demand deposits. The change in the fair value of these derivatives is recorded in accumulated other comprehensive income (loss), and is subsequently reclassified into earnings in the period that the forecasted transactions affect earnings. The fair value of the Company's derivatives is determined using discounted cash flow analysis using observable market-based inputs, which are considered Level 2 inputs. Assets Measured at Fair Value on a Non-Recurring Basis The valuation techniques described below were used to estimate fair value of financial instruments measured on a non-recurring basis as of June 30, 2024 and December 31, 2023. Collateral-Dependent Impaired Loans For loans measured for impairment based on the fair value of the underlying collateral, fair value was estimated using a market approach. The Company measures the fair value of collateral underlying impaired loans primarily through obtaining independent appraisals that rely upon quoted market prices for similar assets in active markets. These appraisals include adjustments, on an individual case-by-case basis, to comparable assets based on the appraisers’ market knowledge and experience, as well as adjustments for estimated costs to sell between 5% and 10%. Management classifies these loans as Level 3 within the fair value hierarchy. Foreclosed Assets Assets acquired through foreclosure or deed in lieu of foreclosure are carried at fair value, less estimated selling costs, which range between 5% and 10%. Fair value is generally based on independent appraisals that rely upon quoted market prices for similar assets in active markets. These appraisals include adjustments, on an individual case basis, to comparable assets based on the appraisers’ market knowledge and experience, and are classified as Level 3. When an asset is acquired, the excess of the loan balance over fair value less estimated selling costs is charged to the allowance for credit losses. A reserve for foreclosed assets may be established to provide for possible write-downs and selling costs that occur subsequent to foreclosure. Foreclosed assets are carried net of the related reserve. Operating results from real estate owned, including rental income, operating expenses, and gains and losses realized from the sales of real estate owned, are recorded as incurred. There were no changes to the valuation techniques for fair value measurements as of June 30, 2024 or December 31, 2023. The following tables present the assets and liabilities reported on the consolidated statements of financial condition at their fair values as of June 30, 2024 and December 31, 2023, by level within the fair value hierarchy (in thousands): Fair Value Measurements at Reporting Date Using: June 30, 2024 Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Measured on a recurring basis: Available for sale debt securities: U.S. Treasury obligations $ 335,031 335,031 — — Government-agency obligations 166,202 114,369 51,833 — Mortgage-backed securities 1,849,184 — 1,849,184 — Asset-backed securities 53,053 — 53,053 — State and municipal obligations 126,558 — 126,558 — Corporate obligations 96,755 — 96,755 — Total available for sale debt securities 2,626,783 449,400 2,177,383 — Equity securities 19,250 19,250 — — Derivative assets 208,316 — 208,316 — $ 2,854,349 468,650 2,385,699 — Derivative liabilities $ 193,670 — 193,670 — Measured on a non-recurring basis: Loans measured for impairment based on the fair value of the underlying collateral $ 18,413 — — 18,413 Foreclosed assets 11,119 — — 11,119 $ 29,532 — — 29,532 Fair Value Measurements at Reporting Date Using: December 31, 2023 Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Measured on a recurring basis: Available for sale debt securities: U.S. Treasury obligations $ 253,878 253,878 — — Government-agency obligations 27,498 — 27,498 — Mortgage-backed securities 1,285,609 — 1,285,609 — Asset-backed securities 32,235 — 32,235 — State and municipal obligations 56,584 — 56,584 — Corporate obligations 34,308 — 34,308 — Total available for sale debt securities 1,690,112 253,878 1,436,234 — Equity Securities 1,270 1,270 — — Derivative assets 101,754 — 101,754 — $ 1,793,136 255,148 1,537,988 — Derivative liabilities $ 88,835 — 88,835 — Measured on a non-recurring basis: Loans measured for impairment based on the fair value of the underlying collateral $ 24,139 — — 24,139 Foreclosed assets 11,651 — — 11,651 $ 35,790 — — 35,790 There were no transfers into or out of Level 3 during the three and six months ended June 30, 2024. Other Fair Value Disclosures The Company is required to disclose estimated fair value of financial instruments, both assets and liabilities on- and off- the balance sheet, for which it is practicable to estimate fair value. The following is a description of valuation methodologies used for those assets and liabilities. Cash and Cash Equivalents For cash and due from banks, federal funds sold and short-term investments, the carrying amount approximates fair value. As of June 30, 2024 and December 31, 2023, $70,000 was included in cash and cash equivalents, representing cash collateral pledged to secure loan level swaps and risk participation agreements. Held to Maturity Debt Securities For held to maturity debt securities, fair value was estimated using a market approach. The majority of the Company’s securities are fixed income instruments that are not quoted on an exchange, but are traded in active markets. Prices for these instruments are obtained through third party data service providers or dealer market participants with whom the Company has historically transacted both purchases and sales of securities. Prices obtained from these sources include market quotations and matrix pricing. Matrix pricing, a Level 2 input, is a mathematical technique used principally to value certain securities by benchmarking to comparable securities. Management evaluates the quality of Level 2 matrix pricing through comparison to similar assets with greater liquidity and evaluation of projected cash flows. As management is responsible for the determination of fair value, it performs quarterly analyses on the prices received from the pricing service to determine whether the prices are reasonable estimates of fair value. Specifically, management compares the prices received from the pricing service to a secondary pricing source. Additionally, management compares changes in the reported market values and returns to relevant market indices to test the reasonableness of the reported prices. The Company’s internal price verification procedures and review of fair value methodology documentation provided by independent pricing services has generally not resulted in adjustment in the prices obtained from the pricing service. The Company also holds debt instruments issued by the U.S. government and U.S. government-sponsored agencies that are traded in active markets with readily accessible quoted market prices that are considered Level 1 within the fair value hierarchy. Federal Home Loan Bank of New York Stock The carrying value of FHLBNY stock is its cost. The fair value of FHLBNY stock is based on redemption at par value. The Company classifies the estimated fair value as Level 1 within the fair value hierarchy. Loans Fair values are estimated for portfolios of loans with similar financial characteristics. Loans are segregated by type such as commercial mortgage, residential mortgage, commercial, construction and consumer. Each loan category is further segmented into fixed and adjustable-rate interest terms and into performing and non-performing categories. The fair value of performing loans was estimated using a combination of techniques, including a discounted cash flow model that utilizes a discount rate that reflects the Company’s current pricing for loans with similar characteristics and remaining maturity, adjusted by an amount for estimated credit losses inherent in the portfolio at the balance sheet date (i.e. exit pricing). The rates take into account the expected yield curve, as well as an adjustment for prepayment risk, when applicable. The Company classifies the estimated fair value of its loan portfolio as Level 3. The fair value for significant non-performing loans was based on recent external appraisals of collateral securing such loans, adjusted for the timing of anticipated cash flows. The Company classifies the estimated fair value of its non-performing loan portfolio as Level 3. Deposits The fair value of deposits with no stated maturity, such as non-interest bearing demand deposits and savings deposits, was equal to the amount payable on demand and classified as Level 1. The estimated fair value of certificates of deposit was based on the discounted value of contractual cash flows. The discount rate was estimated using the Company’s current rates offered for deposits with similar remaining maturities. The Company classifies the estimated fair value of its certificates of deposit portfolio as Level 2. Borrowed Funds The fair value of borrowed funds was estimated by discounting future cash flows using rates available for debt with similar terms and maturities and is classified by the Company as Level 2 within the fair value hierarchy. Subordinated Debentures The fair value of borrowed funds was estimated based on bid/ask prices from brokers for similar types of instruments and is classified by the Company as Level 2 within the fair value hierarchy. Commitments to Extend Credit and Letters of Credit The fair value of commitments to extend credit and letters of credit was estimated using the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the present creditworthiness of the counterparties. For fixed rate loan commitments, fair value also considers the difference between current levels of interest rates and the committed rates. The Company classifies these commitments as Level 3 within the fair value hierarchy. Limitations Fair value estimates are made at a specific point in time, based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time the Company’s entire holdings of a particular financial instrument. Because no market exists for a significant portion of the Company’s financial instruments, fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and, therefore, cannot be determined with precision. Changes in assumptions could significantly affect the estimates. Fair value estimates are based on existing on- and off-balance sheet financial instruments without attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not considered financial instruments. Significant assets and liabilities that are not considered financial assets or liabilities include goodwill and other intangibles, deferred tax assets and premises and equipment. In addition, the tax ramifications related to the realization of the unrealized gains and losses can have a significant effect on fair value estimates and have not been considered in the estimates. The following tables present the Company’s financial instruments at their carrying and fair values as of June 30, 2024 and December 31, 2023. Fair values are presented by level within the fair value hierarchy.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative and Hedging Activities	Derivative and Hedging Activities The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through the management of its core business activities. The Company manages economic risks, including interest rate, liquidity, and credit risk, primarily by managing the amount, sources, and duration of its assets and liabilities. Non-designated Hedges. Derivatives not designated in qualifying hedging relationships are not speculative and result from a service the Company provides to certain qualified commercial borrowers in loan related transactions which, therefore, are not used to manage interest rate risk in the Company’s assets or liabilities. The Company may execute interest rate swaps with qualified commercial banking customers to facilitate their respective risk management strategies. Those interest rate swaps are simultaneously hedged by offsetting interest rate swaps that the Company executes with a third party, such that the Company minimizes its net risk exposure resulting from such transactions. The interest rate swap agreement which the Company executes with the commercial borrower is collateralized by the borrower's commercial real estate financed by the Company. As the Company has not elected to apply hedge accounting and these interest rate swaps do not meet the hedge accounting requirements, changes in the fair value of both the customer swaps and the offsetting swaps are recognized directly in earnings. As of June 30, 2024 and December 31, 2023, the Company had 321 and 154 loan related interest rate swaps with aggregate notional amounts of $4.64 billion and $2.30 billion, respectively. The Company periodically enters into risk participation agreements ("RPAs"), with the Company functioning as either the lead institution, or as a participant when another company is the lead institution on a commercial loan. These RPAs are entered into to manage the credit exposure on interest rate contracts associated with these loan participation agreements. Under the RPAs, the Company will either receive or make a payment in the event the borrower defaults on the related interest rate contract. The Company has minimum collateral posting thresholds with certain of its risk participation counterparties, and has posted collateral of $70,000 against the potential risk of default by the borrower under these agreements. For June 30, 2024 and December 31, 2023, the Company had 8 and 12 credit derivatives, respectively, with aggregate notional amounts of $87.7 million and $142.8 million, respectively, from participations in interest rate swaps as part of these loan participation arrangements. As of June 30, 2024, both the asset and liability positions of these fair value credit derivatives were insignificant, compared to $17,000 and $8,000, respectively, as of December 31, 2023. Cash Flow Hedges of Interest Rate Risk. The Company’s objective in using interest rate derivatives is to add stability to interest expense and to manage its exposure to interest rate movements. To accomplish this objective, the Company primarily uses interest rate swaps as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable payment amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. Changes in the fair value of derivatives designated and that qualify as cash flow hedges of interest rate risk are recorded in accumulated other comprehensive (loss) income and are subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. During the three and six months ended June 30, 2024 and 2023, such derivatives were used to hedge the variable cash outflows associated with FHLBNY borrowings and brokered demand deposits. Amounts reported in accumulated other comprehensive income related to derivatives will be reclassified to interest expense as interest payments are made on the Company’s borrowings or demand deposits. During the next twelve months, the Company estimates that $9.9 million will be reclassified as a reduction to interest expense. As of June 30, 2024, the Company had 7 outstanding interest rate derivatives with an aggregate notional amount of $375.0 million that were each designated as a cash flow hedge of interest rate risk, compared to 9 outstanding interest rate derivatives with an aggregate notional amount of $455.0 million, as of December 31, 2023. The Company is party to master netting arrangements with its financial institution counterparties; however, the Company does not offset assets and liabilities under these arrangements for financial statement presentation purposes. The master netting arrangements provide for a single net settlement of all swap agreements, as well as collateral, in the event of default on, or termination of, any one contract. Collateral, usually in the form of cash or marketable investment securities, is posted by or received from the counterparty with net liability or asset positions, respectively, in accordance with contract thresholds. Master repurchase agreements which include “right of set-off” provisions generally have a legally enforceable right to offset recognized amounts. In such cases, the collateral would be used to settle the fair value of the swap or repurchase agreement should the Company be in default. Total amount of collateral held or pledged cannot exceed the net derivative fair values with the counterparty. The tables below present a gross presentation, the effects of offsetting, and a net presentation of the Company’s financial instruments that are eligible for offset in the Consolidated Statements of Condition as of June 30, 2024 and December 31, 2023 (in thousands).

In addition, the Company has agreements with certain of its dealer counterparties which contain a provision that if the Company fails to maintain its status as a well or adequately capitalized institution, then the counterparty could terminate the derivative positions and the Company would be required to settle its obligations under the agreements.

Revenue Recognition

Revenue from Contract with Customer [Abstract]
Revenue Recognition	Revenue Recognition The Company generates revenue from several business channels. The guidance in ASU 2014-09, Revenue from Contracts with Customers (Topic 606) does not apply to revenue associated with financial instruments, including interest income on loans and investments, which comprise the majority of the Company's revenue. For both the three and six months ended June 30, 2024, the out-of-scope revenue related to financial instruments was 91.8% and 90.5% of the Company's total revenue, compared to 88.5% and 87.6% for the three and six months ended June 30, 2023, respectively. Revenue-generating activities that are within the scope of Topic 606, are components of non-interest income. These revenue streams are generally classified into three categories: wealth management revenue, insurance agency income and banking service charges and other fees. The following table presents non-interest income, segregated by revenue streams in-scope and out-of-scope of Topic 606, for the three and six months ended June 30, 2024 and 2023 (in thousands): Three months ended June 30, Six months ended June 30, 2024 2023 2024 2023 Non-interest income In-scope of Topic 606: Wealth management fees $ 7,769 6,919 15,257 13,834 Insurance agency income 4,488 3,847 9,281 7,950 Banking service charges and other fees: Service charges on deposit accounts 4,208 3,050 7,524 6,413 Debit card and ATM fees 1,174 761 1,861 1,466 Total banking service charges and other fees 5,382 3,811 9,385 7,879 Total in-scope non-interest income 17,639 14,577 33,923 29,663 Total out-of-scope non-interest income 4,636 4,810 9,158 11,877 Total non-interest income $ 22,275 19,387 43,081 41,540 Wealth management fee income represents fees earned from customers as consideration for asset management, investment advisory and trust services. The Company’s performance obligation is generally satisfied monthly and the resulting fees are recognized monthly. The fee is generally based upon the average market value of the assets under management for the month and the applicable fee rate. The monthly accrual of wealth management fees is recorded in other assets on the Company's Consolidated Statements of Financial Condition. Fees are received from the customer on a monthly basis. The Company does not earn performance-based incentives. To a lesser extent, optional services such as tax return preparation and estate settlement are also available to existing customers. The Company’s performance obligation for these transaction-based services is generally satisfied, and related revenue recognized, at either a point in time when the service is completed, or in the case of estate settlement, over a relatively short period of time, as each service component is completed. Insurance agency income, consisting of commissions and fees, is generally recognized as of the effective date of the insurance policy. Commission revenues related to installment billings are recognized on the invoice date. Subsequent commission adjustments are recognized upon the receipt of notification from insurance companies concerning matters necessitating such adjustments. Profit-sharing contingent commissions are recognized when determinable, which is generally when such commissions are received from insurance companies, or when the Company receives formal notification of the amount of such payments. Service charges on deposit accounts include account analysis fees and other deposit-related fees. These fees are generally transaction-based, or time-based services. The Company's performance obligation for these services is generally satisfied, and revenue recognized, at the time the transaction is completed, or the service rendered. Fees for these services are generally received from the customer either at the time of transaction, or monthly. Debit card and ATM fees are generally transaction-based. Debit card revenue is primarily comprised of interchange fees earned when a customer's Company card is processed through a card payment network. ATM fees are largely generated when a Company cardholder uses a non-Company ATM, or a non-Company cardholder uses a Company ATM. The Company's performance obligation for these services is satisfied when the service is rendered. Payment is generally received at the time of transaction or monthly. Out-of-scope non-interest income primarily consists of Bank-owned life insurance and net fees on loan level interest rate swaps, along with gains and losses on the sale of loans and foreclosed real estate, loan prepayment fees and loan servicing fees. None of these revenue streams are subject to the requirements of Topic 606.

The Company’s lease agreements often include one or more options to renew at the Company’s discretion. If at lease inception the Company considers the exercising of a renewal option to be reasonably certain, the Company will include the extended term in the calculation of the right-of-use asset and lease liability. Regarding the discount rate, Topic 842 requires the use of the rate implicit in the lease whenever this rate is readily determinable. As this rate is rarely determinable, the Company utilizes its incremental borrowing rate at lease inception based upon the term of the lease. For operating leases existing prior to January 1, 2019, the rate for the remaining lease term as of January 1, 2019 was applied. All of the leases in which the Company is the lessee are classified as operating leases and are primarily comprised of real estate properties for branches and administrative offices with terms extending through 2046. As of June 30, 2024, the weighted-average remaining lease term and the weighted-average discount rate for the Company's operating leases were 7.6 years and 2.06%, respectively. The following tables represent lease costs and other lease information for the Company's operating leases. The variable lease cost primarily represents variable payments such as common area maintenance and utilities (in thousands): Three months ended June 30, 2024 Three months ended June 30, 2023 Lease Costs Operating lease cost $ 3,771 2,629 Variable lease cost 705 842 Total lease cost $ 4,476 3,471 Six months ended June 30, 2024 Six months ended June 30, 2023 Lease Costs Operating lease cost $ 6,398 5,257 Variable lease cost 1,491 1,722 Total lease cost $ 7,889 6,979 Cash paid for amounts included in the measurement of lease liabilities: Six months ended June 30, 2024 Six months ended June 30, 2023 Operating cash flows from operating leases $ 5,698 4,776 During the three and six months ended June 30, 2024, the Company added 39 new lease obligations related to the Lakeland merger.

Impact of Recent Accounting Pronouncements	Summary of Significant Accounting Policies A. Basis of Financial Statement Presentation The accompanying unaudited consolidated financial statements include the accounts of Provident Financial Services, Inc. (the "Company") and its wholly owned subsidiary, Provident Bank (the “Bank") and its wholly owned subsidiaries. In preparing the interim unaudited consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the consolidated statements of financial condition and the consolidated statements of income for the periods presented. Actual results could differ from these estimates. The allowance for credit losses is a material estimate that is particularly susceptible to near-term change. The interim unaudited consolidated financial statements reflect all normal and recurring adjustments, which are, in the opinion of management, considered necessary for a fair presentation of the financial condition and results of operations for the periods presented. The results of operations for the three and six months ended June 30, 2024 are not necessarily indicative of the results of operations that may be expected for all of 2024. Certain information and note disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission. Additionally, certain comparative balances on the interim unaudited consolidated financial statements have been reclassified to conform to the current year’s presentation. These unaudited consolidated financial statements should be read in conjunction with the December 31, 2023 Annual Report to Stockholders on Form 10-K. B. Earnings Per Share The following is a reconciliation of the numerators and denominators of the basic and diluted earnings per share calculations for the three and six months ended June 30, 2024 and 2023 (dollars in thousands, except per share amounts): Three months ended June 30, 2024 2023 Net Weighted Per Net Weighted Per Net (loss) income $ (11,485) $ 32,003 Basic earnings per share: (Loss) Income available to common stockholders $ (11,485) 102,957,521 $ (0.11) $ 32,003 74,823,272 $ 0.43 Dilutive shares — 6,915 Diluted earnings per share: (Loss) Income available to common stockholders $ (11,485) 102,957,521 $ (0.11) $ 32,003 74,830,187 $ 0.43 Six months ended June 30, 2024 2023 Net Weighted Per Net Weighted Per Net income $ 20,596 $ 72,539 Basic earnings per share: Income available to common stockholders $ 20,596 89,108,775 $ 0.23 $ 72,539 74,734,795 $ 0.97 Dilutive shares 7,815 32,053 Diluted earnings per share: Income available to common stockholders $ 20,596 89,116,590 $ 0.23 $ 72,539 74,766,848 $ 0.97 Anti-dilutive stock options and awards as of June 30, 2024 and 2023, totaling 1.5 million shares and 1.3 million shares, respectively, were excluded from the earnings per share calculations.

Loans Receivable and Allowance for Credit Losses The impact of utilizing the current expected credit loss ("CECL") methodology approach to calculate the allowance for credit losses on loans is significantly influenced by the composition, characteristics and quality of the Company’s loan portfolio, as well as the prevailing economic conditions and forecast utilized. Material changes to these and other relevant factors may result in greater volatility to the allowance for credit losses, and therefore, greater volatility to the Company’s reported earnings. For the three and six months ended June 30, 2024, an initial CECL provision for credit losses on loans and commitments to extend credit of $65.2 million was recorded as part of the Lakeland merger in accordance with GAAP requirements for accounting for business combinations. See Notes 4 and 10 to the Consolidated Financial Statements for more information on the allowance for credit losses on loans and off-balance sheet credit exposures. D. Goodwill Goodwill represents the excess of the purchase price over the estimated fair value of identifiable net assets acquired through purchase acquisitions. Goodwill with an indefinite useful life is not amortized, but is evaluated for impairment on an annual basis, or more frequently if events or changes in circumstances indicate potential impairment between annual measurement dates. Goodwill is analyzed for impairment at least once a year. The Company prepares a qualitative assessment in determining whether goodwill may be impaired. The factors considered in the assessment include macroeconomic conditions, industry and market conditions and overall financial performance of the Company, among others. The Company completed its most recent annual goodwill impairment test as of July 1, 2024. The Company performed a qualitative analysis of goodwill and concluded that no triggering events were identified and therefore a test for impairment between annual tests was not required. Accounting Pronouncements Not Yet Adopted In December 2023, FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures”. The amendments in this ASU require improved annual income tax disclosures surrounding rate reconciliation, income taxes paid, and other disclosures. This update will be effective for financial statements issued for fiscal years beginning after December 15, 2024, with early adoption in the interim period permitted. The Company is currently evaluating the impact of this standard on the consolidated financial statements.

Accounting Policies [Abstract]
Basis of Financial Statement Presentation	Basis of Financial Statement Presentation The accompanying unaudited consolidated financial statements include the accounts of Provident Financial Services, Inc. (the "Company") and its wholly owned subsidiary, Provident Bank (the “Bank") and its wholly owned subsidiaries. In preparing the interim unaudited consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the consolidated statements of financial condition and the consolidated statements of income for the periods presented. Actual results could differ from these estimates. The allowance for credit losses is a material estimate that is particularly susceptible to near-term change. The interim unaudited consolidated financial statements reflect all normal and recurring adjustments, which are, in the opinion of management, considered necessary for a fair presentation of the financial condition and results of operations for the periods presented. The results of operations for the three and six months ended June 30, 2024 are not necessarily indicative of the results of operations that may be expected for all of 2024.

Goodwill	GoodwillGoodwill represents the excess of the purchase price over the estimated fair value of identifiable net assets acquired through purchase acquisitions. Goodwill with an indefinite useful life is not amortized, but is evaluated for impairment on an annual basis, or more frequently if events or changes in circumstances indicate potential impairment between annual measurement dates. Goodwill is analyzed for impairment at least once a year. The Company prepares a qualitative assessment in determining whether goodwill may be impaired. The factors considered in the assessment include macroeconomic conditions, industry and market conditions and overall financial performance of the Company, among others. The Company completed its most recent annual goodwill impairment test as of July 1, 2024. The Company performed a qualitative analysis of goodwill and concluded that no triggering events were identified and therefore a test for impairment between annual tests was not required.
Fair Value Measurements	The Company utilizes fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. The determination of fair values of financial instruments often requires the use of estimates. Where quoted market values in an active market are not readily available, management utilizes various valuation techniques to estimate fair value. Fair value is an estimate of the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. However, in many instances fair value estimates may not be substantiated by comparison to independent markets and may not be realized in an immediate sale of the financial instrument. GAAP establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are as follows: Level 1: Unadjusted quoted market prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities; Level 2: Quoted prices in markets that are not active, or inputs that are observable either directly or indirectly, for substantially the full term of the asset or liability; and Level 3: Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity). A financial instrument’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. The valuation techniques are based upon the unpaid principal balance only, and exclude any accrued interest or dividends at the measurement date. Interest income and expense and dividend income are recorded within the consolidated statements of income depending on the nature of the instrument using the effective interest method based on acquired discount or premium. Assets and Liabilities Measured at Fair Value on a Recurring Basis The valuation techniques described below were used to measure fair value of financial instruments in the table below on a recurring basis as of June 30, 2024 and December 31, 2023. Available for Sale Debt Securities, at Fair Value For available for sale debt securities, fair value was estimated using a market approach. The majority of the Company’s securities are fixed income instruments that are not quoted on an exchange, but are traded in active markets. Prices for these instruments are obtained through third-party data service providers or dealer market participants with whom the Company has historically transacted both purchases and sales of securities. Prices obtained from these sources include market quotations and matrix pricing. Matrix pricing, a Level 2 input, is a mathematical technique used principally to value certain securities by benchmarking to comparable securities. The Company evaluates the quality of Level 2 matrix pricing through comparison to similar assets with greater liquidity and evaluation of projected cash flows. As management is responsible for the determination of fair value, it performs quarterly analyses on the prices received from the pricing service to determine whether the prices are reasonable estimates of fair value. Specifically, management compares the prices received from the pricing service to a secondary pricing source. Additionally, management compares changes in the reported market values and returns to relevant market indices to test the reasonableness of the reported prices. The Company’s internal price verification procedures and review of fair value methodology documentation provided by independent pricing services has generally not resulted in an adjustment in the prices obtained from the pricing service. The Company also holds debt instruments issued by the U.S. government that are traded in active markets with readily accessible quoted market prices that are considered Level 1 within the fair value hierarchy. Equity Securities at Fair Value The Company holds equity securities that are traded in active markets with readily accessible quoted market prices that are considered Level 1 inputs. Derivatives The Company records all derivatives on the statements of financial condition at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. The Company has interest rate derivatives resulting from a service provided to certain qualified borrowers in a loan related transaction which, therefore, are not used to manage interest rate risk in the Company’s assets or liabilities. As such, all changes in fair value of these derivatives are recognized directly in earnings. The Company also uses interest rate swaps as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges, and which satisfy hedge accounting requirements, involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without the exchange of the underlying notional amount. These derivatives were used to hedge the variable cash outflows associated with FHLBNY borrowings and brokered demand deposits. The change in the fair value of these derivatives is recorded in accumulated other comprehensive income (loss), and is subsequently reclassified into earnings in the period that the forecasted transactions affect earnings. The fair value of the Company's derivatives is determined using discounted cash flow analysis using observable market-based inputs, which are considered Level 2 inputs. Assets Measured at Fair Value on a Non-Recurring Basis The valuation techniques described below were used to estimate fair value of financial instruments measured on a non-recurring basis as of June 30, 2024 and December 31, 2023. Collateral-Dependent Impaired Loans For loans measured for impairment based on the fair value of the underlying collateral, fair value was estimated using a market approach. The Company measures the fair value of collateral underlying impaired loans primarily through obtaining independent appraisals that rely upon quoted market prices for similar assets in active markets. These appraisals include adjustments, on an individual case-by-case basis, to comparable assets based on the appraisers’ market knowledge and experience, as well as adjustments for estimated costs to sell between 5% and 10%. Management classifies these loans as Level 3 within the fair value hierarchy.
Revenue Recognition	Wealth management fee income represents fees earned from customers as consideration for asset management, investment advisory and trust services. The Company’s performance obligation is generally satisfied monthly and the resulting fees are recognized monthly. The fee is generally based upon the average market value of the assets under management for the month and the applicable fee rate. The monthly accrual of wealth management fees is recorded in other assets on the Company's Consolidated Statements of Financial Condition. Fees are received from the customer on a monthly basis. The Company does not earn performance-based incentives. To a lesser extent, optional services such as tax return preparation and estate settlement are also available to existing customers. The Company’s performance obligation for these transaction-based services is generally satisfied, and related revenue recognized, at either a point in time when the service is completed, or in the case of estate settlement, over a relatively short period of time, as each service component is completed. Insurance agency income, consisting of commissions and fees, is generally recognized as of the effective date of the insurance policy. Commission revenues related to installment billings are recognized on the invoice date. Subsequent commission adjustments are recognized upon the receipt of notification from insurance companies concerning matters necessitating such adjustments. Profit-sharing contingent commissions are recognized when determinable, which is generally when such commissions are received from insurance companies, or when the Company receives formal notification of the amount of such payments. Service charges on deposit accounts include account analysis fees and other deposit-related fees. These fees are generally transaction-based, or time-based services. The Company's performance obligation for these services is generally satisfied, and revenue recognized, at the time the transaction is completed, or the service rendered. Fees for these services are generally received from the customer either at the time of transaction, or monthly. Debit card and ATM fees are generally transaction-based. Debit card revenue is primarily comprised of interchange fees earned when a customer's Company card is processed through a card payment network. ATM fees are largely generated when a Company cardholder uses a non-Company ATM, or a non-Company cardholder uses a Company ATM. The Company's performance obligation for these services is satisfied when the service is rendered. Payment is generally received at the time of transaction or monthly. Out-of-scope non-interest income primarily consists of Bank-owned life insurance and net fees on loan level interest rate swaps, along with gains and losses on the sale of loans and foreclosed real estate, loan prepayment fees and loan servicing fees. None of these revenue streams are subject to the requirements of Topic 606.
