Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Informational Disclosures	Basis of Presentation and Informational Disclosures Northwest Bancshares, Inc. (the “Company” or “NWBI”), a Maryland corporation headquartered in Columbus, Ohio, is a bank holding company regulated by the Board of Governors of the Federal Reserve System (“FRB”). The primary activity of the Company is the ownership of all of the issued and outstanding common stock of Northwest Bank, a Pennsylvania-chartered savings bank (“Northwest”). Northwest is regulated by the Federal Deposit Insurance Corporation (“FDIC”) and the Pennsylvania Department of Banking. Northwest operates 142 community-banking offices throughout Pennsylvania, Western New York, Eastern Ohio, and Indiana. The accompanying unaudited Consolidated Financial Statements include the accounts of the Company and its subsidiary, Northwest, and Northwest’s subsidiaries Northwest Capital Group, Inc., Great Northwest Corporation, and MutualFirst Interest Company, Inc. The unaudited Consolidated Financial Statements have been prepared in accordance with United States generally accepted accounting principles for interim financial information and with the instructions for Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information or footnotes required for complete annual financial statements. In the opinion of management, all adjustments necessary for the fair presentation of the Company’s financial position and results of operations have been included. The Consolidated Financial Statements have been prepared using the accounting policies described in the financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022 updated, as required, for any new pronouncements or changes. Certain items previously reported have been reclassified to conform to the current year’s reporting format. These reclassifications had no effect on the reported results of operations. An adjustment has been made to the Consolidated Statements of Income and Consolidated Statements of Cash Flows for the quarter and six months ended June 30, 2022, to reclassify the provision for credit losses - unfunded commitments, previously presented in other expense, to provide additional transparency to financial statement users. The results of operations for the quarter ended are not necessarily indicative of the results that may be expected for the year ending December 31, 2023, or any other period. Stock-Based Compensation On March 15, 2023, the Company awarded employees 176,623 restricted stock units (“RSUs”) with a weighted average discounted grant date fair value of $11.28. The RSUs vest over a three-year period with the first vesting occurring one year from the grant date. The Company awarded directors 33,048 restricted stock awards (“RSAs”) with a grant date fair value of $12.80 which fully vest one-year from the grant date. Also, the Company awarded employees 176,623 performance share units (“PSUs”) with a discounted grant date fair value of $10.54. The number of PSUs earned will be based on attainment of certain performance criteria over a three-year period, with the actual number of shares issuable ranging between 0% and 150% of the number of PSUs granted. The PSUs have a three-year cliff vesting, from the date of grant, and any PSUs earned will be issued after the vesting period. As of June 30, 2023, we awarded discretionary grants of 168,639 RSUs with a weighted average grant date fair value of $10.92. These shares vest over a two Income Taxes-Uncertain Tax Positions Accounting standards prescribe a comprehensive model for how a company should recognize, measure, present and disclose in its financial statements uncertain tax positions that the company has taken or expects to take on a tax return. A tax benefit from an uncertain position may be recognized only if it is “more likely than not” that the position is sustainable, based on its technical merits. The tax benefit of a qualifying position is the largest amount of tax benefit that is greater than 50% likely of being realized upon ultimate settlement with a taxing authority having full knowledge of all relevant information. We had $473,000 of liability for unrecognized tax benefits as of both June 30, 2023 and December 31, 2022. We recognize interest accrued related to: (1) unrecognized tax benefits in other expenses and (2) refund claims in other operating income. We recognize penalties (if any) in other expenses. We are subject to audit by the Internal Revenue Service and any state in which we conduct business for the tax periods ended December 31, 2022, 2021, 2020 and 2019. Recently Adopted Accounting Standards In March 2022, the Financial Accounting Standards Board ( “ FASB ” ) issued Accounting Standards Update ( “ ASU ” ) No. 2022-02, “Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosure.” This ASU eliminates the accounting guidance for troubled debt restructurings ( “ TDRs ” ), while enhancing disclosure requirements for certain loan modifications when a borrower is experiencing financial difficulty. This ASU also requires the disclosure of current period gross write-offs by year for origination for financing receivables. This guidance is effective for annual periods beginning after December 15, 2022, including interim periods within those years, with early adoption permitted. This ASU is applied prospectively to modifications and write-offs beginning on the first day of the fiscal year of adoption. An entity may elect to adopt a modified retrospective transition method on the recognition and measurement of the TDR guidance. We adopted ASU 2022-02 using a modified retrospective transition approach related to the recognition and measurement of the TDR guidance and on a prospective basis for modification and write-offs. As a result, the Company was not required to adjust its comparative period financial information for effects of the standard or make the new required ASU 2022-02 disclosure for periods before the date of adoption (i.e. January 1, 2023). This change did not have a material effect on our consolidated financial statements. In March 2020, the FASB issued Accounting Standards Update (“ASU”) No. 2020-04, “ Facilitation of the Effects of Reference Rate Reform on Financial Reporting .” This ASU provides temporary optional guidance on contract modifications and hedge accounting to ease the financial reporting burdens of the expected market transition from LIBOR and other interbank offered rates to alternative reference rates. The guidance provides expedients and exceptions for applying GAAP to transactions affected by reference rate reform if certain criteria are met. The amendments primarily include contract modifications and hedge accounting, as well as providing a one-time election for the sale or transfer of debt securities classified as held-to-maturity. This guidance was effective as of March 12, 2020 through December 31, 2022. In December 2022, the FASB issued ASU No. 2022-06, “Reference Rate Reform (Topic 848): Deferral of the Sunset Date to Topic 848”. This guidance extends the guidance of ASU 2022-04 from December 31, 2022 to December 31, 2024. In January 2021, the FASB issued ASU No. 2021-01, “Reference Rate Reform.” This ASU provides amendments, which are elective, and apply to all entities that have derivative instruments that use an interest rate for margining, discounting or contract price alignment of certain derivative instruments that are modified as a result of the reference rate reform. This ASU is effective upon issuance through December 31, 2024, and can be adopted at any time during this period.

Company does not believe that the available-for-sale debt securities that were in an unrealized loss position as of June 30, 2023, which were comprised of 543 individual securities, represents a credit loss impairment. All of these securities were issued by U.S. government agencies, U.S. government-sponsored enterprises, local municipalities, or represent corporate debt. The securities issued by the U.S. government agencies or U.S. government-sponsored enterprises 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 securities issued by local municipalities and the corporate debt issues were all highly rated by major rating agencies and have no history of credit losses. The unrealized losses were primarily attributable to changes in the interest rate environment and not due to the credit quality of these investment securities. The Company does not have the intent to sell these investment securities and it is more likely than not that we will not be required to sell these securities before their anticipated recovery, which may be at maturity. All of the Company ’ s held-to-maturity debt securities are issued by U.S. government agencies or U.S. government-sponsored enterprises. 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 decline in fair value of the held-to-maturity debt securities were primarily attributable to changes in the interest rate environment and not due to the credit quality of these investment securities, therefore, the Company did not record an allowance for credit losses for these securities as of June 30, 2023. The following table presents the credit quality of our held-to-maturity securities, based on the latest information available as of June 30, 2023 (in thousands). The credit ratings are sourced from nationally recognized rating agencies, which include Moody’s and S&P, and they are presented based on asset type. All of our held-to-maturity securities were current in their payment of principal and interest as of June 30, 2023.

When principal forgiveness is provided, the amount of forgiveness is charged off against the allowance for credit losses. In some cases, the Company provides multiple types of concessions to one loan. Typically, one type of concession, such as a term extension, is granted initially. If the borrower continues to experience financial difficulty, another concession, such as principal forgiveness, may be granted. For loans included in the "combination" columns below, multiple types of modifications have been made on the same loan within the current reporting period. The combination is at least two of the following: a term extension, principal forgiveness, an other-than-insignificant payment delay, and/or an interest rate reduction. The following table presents the amortized cost basis of loans as of June 30, 2023 that were both experiencing financial difficulty and modified during the periods indicated, by class and by type of modification. The percentage of the amortized cost basis of loans that were modified to borrowers in financial distress as compared to the amortized cost basis of each class of financial receivable is also presented below.

The following table presents the performance of loans that such loans have been modified since the adoption of ASU 2022-02: Current 30-59 days 60-89 days 90 days or Personal Banking: Residential mortgage loans $ 262 — — — Home equity loans 166 — — — Consumer loans 3 — — — Total Personal Banking 431 — — — Commercial Banking: Commercial real estate loans 81 139 — — Commercial loans — 660 — — Total Commercial Banking 81 799 — — Total loans $ 512 799 — — No loans modified since the adoption of ASU 2022-02 subsequently defaulted during the quarter ended June 30, 2023. The modifications to borrowers experiencing financial distress are included in their respective portfolio segment and the current loan balance and updated loan terms are run through their respective ACL models to arrive at the quantitative portion of the ACL. Subsequent performance of the loans will be measured by delinquency status and will be captured through our ACL models or our qualitative factor assessment, as deemed appropriate. If we no longer believe the loan demonstrates similar risks to their respective portfolio segment an individual assessment will be performed. Upon the Company's determination that a modified loan (or portion of a loan) has subsequently been deemed uncollectible, the loan (or a portion of the loan) is written off. Therefore, the amortized cost basis of the loan is reduced by the uncollectible amount and the allowance for credit losses is adjusted by the same amount.

We analyze loans individually by classifying the loans by credit risk. Credit relationships greater than or equal to $1.0 million classified as special mention or substandard are reviewed quarterly for deterioration or improvement to determine if the loan is appropriately classified. We use the following definitions for risk ratings other than pass: Special Mention — Loans designated as special mention have specific, well-defined risk issues, which create a high level of uncertainty regarding the long-term viability of the business. Loans in this class are considered to have high-risk characteristics. A special mention loan exhibits material negative financial trends due to company-specific or systemic conditions. If these potential weaknesses are not mitigated, they threaten the borrower’s capacity to meet its debt obligations. Special mention loans still demonstrate sufficient financial flexibility to react to and positively address the root cause of the adverse financial trends without significant deviations from their current business strategy. Their potential weaknesses deserve our close attention and warrant enhanced monitoring. Substandard — Loans classified as substandard are inadequately protected by the current net worth and payment capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that we will sustain some loss if the deficiencies are not corrected. Doubtful — Loans classified as doubtful have all the weaknesses inherent in those classified as substandard. In addition, those weaknesses make collection or liquidation in full highly questionable and improbable. A loan classified as doubtful exhibits discernible loss potential, but a complete loss seems very unlikely. The possibility of a loss on a doubtful loan is high, but because of certain important and reasonably specific pending factors that may strengthen the loan, its classification as an estimated loss is deferred until a more exact status can be determined. Loss — Loans classified as loss are considered uncollectible and of such value that the continuance as a loan is not warranted. A loss classification does not mean that the loan has no recovery or salvage value; instead, it means that it is not practical or desirable to defer writing off all or a portion of a basically worthless loan even though partial recovery may be possible in the future. For Personal Banking loans a pass risk rating is maintained until they are 90 days or greater past due, and risk rating reclassification is based primarily on past due status of the loan. The risk rating categories can generally be described by the following groupings: Pass — Loans classified as pass are homogeneous loans that are less than 90 days past due from the required payment date at month-end. Substandard — Loans classified as substandard are homogeneous loans that are greater than 90 days past due from the required payment date at month-end, or homogenous retail loans that are greater than 180 days past due from the required payment date at month-end that has been written down to the value of underlying collateral, less costs to sell.

At June 30, 2023, the carrying value of these loans was $6.013 billion. Certain of these borrowings are subject to restrictions or penalties in the event of prepayment. The revolving line of credit with the FHLB of Pittsburgh carries a commitment of $250.0 million. The rate is adjusted daily by the FHLB of Pittsburgh, and any borrowings on this line may be repaid at any time without penalty. At June 30, 2023 and December 31, 2022, the balance of the revolving line of credit was $28.0 million and $51.3 million, respectively. At June 30, 2023 and December 31, 2022, collateralized borrowings due within one year were $63.9 million and $105.8 million, respectively. These borrowings are collateralized by cash or various securities held in safekeeping by the FHLB. At June 30, 2023, the carrying value of the cash and securities used as collateral was $94.6 million. At June 30, 2023 and December 31, 2022, collateral received was $40.5 million and $24.1 million, respectively. This represents collateral posted to us from our derivative counterparties. At each of the periods ended June 30, 2023 and December 31, 2022, term notes payable to the FHLB of Pittsburgh due within one year were $500.0 million. The June 30, 2023 total is made up of eight advances: $100.0 million at 5.52% maturing July 7, 2023; $100.0 million at 5.37% maturing July 14, 2023; $100.0 million at 5.39% maturing July 21, 2023; $100.0 million at 5.39% maturing July 28, 2023; $25.0 million at 5.46% maturing August 11, 2023; $25.0 million at 5.45% maturing August 14, 2023; $25.0 million at 5.48% maturing August 21, 2023; and $25.0 million at 5.51% maturing August 31, 2023. On September 9, 2020, the Company issued $125.0 million of 4.00% fixed-to-floating rate subordinated notes with a maturity date of September 15, 2030. The subordinated notes, which qualify as Tier 2 capital, bear interest at an annual rate of 4.00%, payable semi-annually in arrears commencing on March 15, 2021, and a floating rate of interest equivalent to the 3-month Secured Overnight Financing Rate (“SOFR”) plus 3.89% payable quarterly in arrears commencing on December 15, 2025. During the year-ended December 31, 2022 the Company repurchased $10.2 million of subordinated notes leaving $114.8 million of subordinated notes outstanding. The subordinated debt issuance costs of approximately $1.8 million are being amortized over five years on a straight-line basis into interest expense. At June 30, 2023 and December 31, 2022, subordinated debentures, net of issuance costs, were $114.0 million and $113.8 million, respectively. (b) Trust Preferred Securities The Company has seven statutory business trusts: Northwest Bancorp Capital Trust III, a Delaware statutory business trust, Northwest Bancorp Statutory Trust IV, a Connecticut statutory business trust, LNB Trust II, a Delaware statutory business trust, Union National Capital Trust I (“UNCT I”), a Delaware statutory business trust, Union National Capital Trust II (“UNCT II”), a Delaware statutory business trust, MFBC Statutory Trust I, a Delaware statutory trust, and Universal Preferred Trust, a Delaware statutory trust (the “Trusts”). The Trusts exist solely to issue preferred securities to third parties for cash, issue common securities to the Company in exchange for capitalization of the Trusts, invest the proceeds from the sale of trust securities in an equivalent amount of debentures of the Company, and engage in other activities that are incidental to those previously listed. The Trusts have invested the proceeds of the offerings in junior subordinated deferrable interest debentures issued by the Company. The structure of these debentures mirrors the structure of the trust-preferred securities. These subordinated debentures are the sole assets of the Trusts. As the shareholders of the trust preferred securities are the primary beneficiaries of the Trusts, the Trusts are not consolidated in our financial statements. The following table sets forth a summary of the cumulative trust preferred securities and the junior subordinated debt held by the Trust as of the date listed.

Cash distributions on the trust securities are made on a quarterly basis to the extent interest on the debentures is received by the Trusts. We have the right to defer payment of interest on the subordinated debentures at any time, or from time-to-time, for periods not exceeding five years. If interest payments on the subordinated debentures are deferred, the distributions on the trust securities also are deferred. To date there have been no interest deferrals. Interest on the subordinated debentures and distributions on the trust securities is cumulative. Our obligation constitutes a full, irrevocable, and unconditional guarantee on a subordinated basis of the obligations of the trust under the preferred securities. The Trusts must redeem the preferred securities when the debentures are paid at maturity or upon an earlier redemption of the debentures to the extent the debentures are redeemed. All or part of the debentures may be redeemed at any time. Also, the debentures may be redeemed at any time if existing laws or regulations, or the interpretation or application of these laws or regulations, change causing: • the interest on the debentures to no longer be deductible by the Company for federal income tax purposes; • the trusts to become subject to federal income tax or to certain other taxes or governmental charges; • the trusts to register as an investment company; or • the preferred securities to no longer qualify as Tier I capital. We may, at any time, dissolve any of the Trusts and distribute the debentures to the trust security holders, subject to receipt of any required regulatory approvals.

Guarantees

Guarantees [Abstract]
Guarantees	Guarantees We issue standby letters of credit in the normal course of business. Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. Standby letters of credit generally are contingent upon the failure of the customer to perform according to the terms of the underlying contract with the third party. We are required to perform under a standby letter of credit when drawn upon by the guaranteed third party in the case of nonperformance by our customer. The credit risk associated with standby letters of credit is essentially the same as that involved in extending loans to customers and is subject to normal loan underwriting procedures. Collateral may be obtained based on management’s credit assessment of the customer. At June 30, 2023, the maximum potential amount of future payments we could be required to make under these non-recourse standby letters of credit was $39.9 million, of which $26.3 million is fully collateralized. At June 30, 2023, we had a liability which represents deferred income of $870,000 related to the standby letters of credit.

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share Basic earnings per common share (“EPS”) is computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding for the period, without considering any dilutive items. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the Company. The following table sets forth the computation of basic and diluted EPS (in thousands, except share data and per share amounts): Quarter ended June 30, Six months ended June 30, 2023 2022 2023 2022 Net income $ 33,044 33,426 66,723 61,713 Less: Dividends and undistributed earnings allocated to participating securities 86 159 174 294 Net income available to common shareholders $ 32,958 33,267 66,549 61,419 Weighted average common shares outstanding 126,620,383 126,059,165 126,559,784 125,960,997 Add: Participating shares outstanding 331,088 604,613 331,088 604,613 Total weighted average common shares and dilutive potential shares 126,951,471 126,663,778 126,890,872 126,565,610 Basic earnings per share $ 0.26 0.26 0.53 0.49 Diluted earnings per share $ 0.26 0.26 0.52 0.49

Fair Value Disclosures [Abstract]
Disclosures About Fair Value of Financial Instruments	Disclosures About Fair Value of Financial Instruments We are required to disclose fair value information about financial instruments whether or not recognized in the Consolidated Statement of Financial Condition. Fair value information of certain financial instruments and all nonfinancial instruments is not required to be disclosed. Accordingly, the aggregate fair value amounts presented do not represent the underlying value of the Company. Financial assets and liabilities recognized or disclosed at fair value on a recurring basis and certain financial assets and liabilities on a non-recurring basis are accounted for using a three-level hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable. This hierarchy gives the highest priority to quoted prices with readily available independent data in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable market inputs (Level 3). When various inputs for measurement fall within different levels of the fair value hierarchy, the lowest level input that has a significant impact on fair value measurement is used. Financial assets and liabilities are categorized based upon the following characteristics or inputs to the valuation techniques: • Level 1 - Financial assets and liabilities for which inputs are observable and are obtained from reliable quoted prices for identical assets or liabilities in actively traded markets. This is the most reliable fair value measurement and includes, for example, active exchange-traded equity securities. • Level 2 - Financial assets and liabilities for which values are based on quoted prices in markets that are not active or for which values are based on similar assets or liabilities that are actively traded. Level 2 also includes pricing models in which the inputs are corroborated by market data, for example, matrix pricing. • Level 3 - Financial assets and liabilities for which values are based on prices or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement. Level 3 inputs include the following: ◦ Quotes from brokers or other external sources that are not considered binding; ◦ Quotes from brokers or other external sources where it cannot be determined that market participants would in fact transact for the asset or liability at the quoted price; and ◦ Quotes and other information from brokers or other external sources where the inputs are not deemed observable. We are responsible for the valuation process and as part of this process may use data from outside sources in establishing fair value. We perform due diligence to understand the inputs used or how the data was calculated or derived. We also corroborate the reasonableness of external inputs in the valuation process. The carrying amounts reported in the Consolidated Statement of Financial Condition approximate fair value for the following financial instruments: cash and cash equivalents, marketable securities available-for-sale, residential mortgage loans held-for-sale, accrued interest receivable, interest rate lock commitments, forward commitments, interest rate swaps, savings and checking deposits, foreign exchange swaps, risk participation agreements, and accrued interest payable. Marketable Securities Where available, market values are based on quoted market prices, dealer quotes, and prices obtained from independent pricing services. Debt Securities — available-for-sale - Generally, debt securities are valued using pricing for similar securities, recently executed transactions and other pricing models utilizing observable inputs. The valuation for most debt securities is classified as Level 2. Securities within Level 2 include corporate bonds, municipal bonds, mortgage-backed securities and U.S. government obligations. Certain debt securities which were AAA rated at purchase do not have an active market and as such we have used an alternative method to determine the fair value of these securities. The fair value has been determined using a discounted cash flow model using market assumptions, which generally include cash flow, collateral and other market assumptions. As such, securities which otherwise would have been classified as Level 2 securities if an active market for those assets or similar assets existed are included herein as Level 3 assets. Debt Securities — held-to-maturity - The fair value of debt securities held-to-maturity is determined in the same manner as debt securities available-for-sale. Loans Receivable Loans with comparable characteristics including collateral and re-pricing structures are segregated for valuation purposes. Each loan pool is separately valued utilizing a discounted cash flow analysis. Projected monthly cash flows are discounted to present value using a market rate for comparable loans, which is not considered an exit price. Characteristics of comparable loans include remaining term, coupon interest, and estimated prepayment speeds. Delinquent loans are separately evaluated given the impact delinquency has on the projected future cash flow of the loan including the approximate discount or market rate, which is not considered an exit price. Loans Held-for-Sale The estimated fair value of loans held-for-sale is based on market bids obtained from potential buyers. FHLB Stock Due to the restrictions placed on transferability of FHLB stock, it is not practical to determine the fair value. FHLB stock is recorded at cost. Deposit Liabilities The estimated fair value of deposits with no stated maturity, which includes demand deposits, money market, and other savings accounts, is the amount payable on demand. Although market premiums paid for depository institutions reflect an additional value for these low-cost deposits, adjusting fair value for any value expected to be derived from retaining those deposits for a future period of time or from the benefit that results from the ability to fund interest-earning assets with these deposit liabilities is prohibited. The fair value estimates of deposit liabilities do not include the benefit that results from the low-cost funding provided by these deposits compared to the cost of borrowing funds in the market. Fair values for time deposits are estimated using a discounted cash flow calculation that applies contractual cost currently being offered in the existing portfolio to current market rates being offered locally for deposits of similar remaining maturities. The valuation adjustment for the portfolio consists of the present value of the difference of these two cash flows, discounted at the assumed market rate of the corresponding maturity Borrowed Funds Fixed rate advances are valued by comparing their contractual cost to the prevailing market cost. The carrying amount of repurchase agreements approximates their fair value. Subordinated Debentures The fair value of our subordinated debentures is calculated using the discounted cash flows at rates observable for other similarly traded liabilities. Junior Subordinated Debentures The fair value of junior subordinated debentures is calculated using the discounted cash flows at the prevailing rate of interest. Interest Rate Lock Commitments and Forward Commitments The fair value of interest rate lock commitments is based on the value of underlying loans held-for-sale which is based on quoted prices for similar loans in the secondary market. This value is then adjusted based on the probability of the loan closing (i.e., the “pull-through” amount, a significant unobservable input). The fair value of forward sale commitments is based on quoted prices from the secondary market based on the settlement date of the contracts. Cash Flow Hedges, Interest Rate and Foreign Exchange Swap Agreements and Risk Participation Agreements The fair value of interest rate swaps is based upon the present value of the expected future cash flows using the SOFR discount curve, the basis for the underlying interest rate. To price interest rate swaps, cash flows are first projected for each payment date using the fixed rate for the fixed side of the swap and the forward rates for the floating side of the swap. These swap cash flows are then discounted to time zero using SOFR zero-coupon interest rates. The sum of the present value of both legs is the fair market value of the interest rate swap. These valuations have been derived from our third party vendor’s proprietary models rather than actual market quotations. The proprietary models are based upon financial principles and assumptions that we believe to be reasonable. The fair value of the foreign exchange swap is derived from proprietary models rather than actual market quotations. The proprietary models are based upon financial principles and assumptions we believe to be reasonable. Risk participation agreements are entered into when Northwest purchases a portion of a commercial loan that has an interest rate swap. Northwest assumes credit risk on its portion of the interest rate swap should the borrower fail to pay as agreed. The value of risk participation agreements is determined based on the value of the swap after considering the credit quality, probability of default, and loss given default of the borrower. Off-Balance Sheet Financial Instruments These financial instruments generally are not sold or traded, and estimated fair values are not readily available. However, the fair value of commitments to extend credit and standby letters of credit is estimated using the fees currently charged to enter into similar agreements. Commitments to extend credit are generally short-term in nature and, if drawn upon, are issued under current market terms. At June 30, 2023 and December 31, 2022, there was no significant unrealized appreciation or depreciation on these financial instruments.

We classify loans individually assessed as nonrecurring Level 3. Mortgage servicing rights - Mortgage servicing rights represent the value of servicing residential mortgage loans, when the mortgage loans have been sold into the secondary market and the associated servicing has been retained. The value is determined through a discounted cash flow analysis, which uses interest rates, prepayment speeds and delinquency rate assumptions as inputs. All of these assumptions require a significant degree of management judgment. Servicing rights and the related mortgage loans are segregated into categories or homogeneous pools based upon common characteristics. Adjustments are only made when the estimated discounted future cash flows are less than the carrying value, as determined by individual pool. As such, mortgage servicing rights are classified as nonrecurring Level 3. Real Estate Owned - Real estate owned is comprised of property acquired through foreclosure or voluntarily conveyed by borrowers. These assets are recorded on the date acquired at the lower of the related loan balance or fair value, less estimated disposition costs, with the fair value being determined by appraisal. Subsequently, foreclosed assets are valued at the lower of the amount recorded at acquisition date or fair value, less estimated disposition costs. We classify real estate owned as nonrecurring Level 3. The following table presents additional quantitative information about assets measured at fair value on a recurring and nonrecurring basis and for which we have utilized Level 3 inputs to determine fair value at June 30, 2023 (in thousands): Fair value Valuation techniques Significant Range (weighted average) Loans individually assessed $ 13,467 Appraisal value (1) Estimated cost to sell 10.0% Mortgage servicing rights 202 Discounted cash flow Annual service cost $92 Prepayment rate 6.6% to 16.3% (10.3%) Expected life (months) 52.1 to 104.2 (74.8) Option adjusted spread 707 basis points Forward yield curve 5.25% to 5.31% Real estate owned, net 371 Appraisal value (1) Estimated cost to sell 15.0% Loans held for sale 16,077 Quoted prices for similar loans in active markets adjusted by an expected pull-through rate Estimated pull-through rate 100.0% (1) Fair value is generally determined through independent appraisals of the underlying collateral, which may include Level 3 inputs that are not identifiable, or by using the discounted cash flow method if the loan is not collateral dependent.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Derivative Financial Instruments We are a party to derivative financial instruments in the normal course of business to manage our own exposure to fluctuations in interest rates and to meet the needs of our customers. The primary derivatives that we use are interest rate swaps and caps and foreign exchange contracts, which are entered into with counterparties that meet established credit standards. We believe that the credit risk inherent in all of our derivative contracts is minimal based on our credit standards and the netting and collateral provisions of the interest rate swap agreements. Derivatives Designated as Hedging Instruments During May 2023, the Company entered into four separate pay-fixed interest rate swaps in order to synthetically convert short-term three month FHLB advances to fixed-rate term funding with an aggregate value of $100 million with maturities ranging from three Derivatives and Hedging . Our cash flow hedges are recorded within other assets on the Consolidated Statement of Financial Condition at their estimated fair value. As long as the hedge remains highly effective the changes in the fair value of derivatives designated, and that qualify, as cash flow hedges is recorded in accumulated other comprehensive income and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. A hedging relationship that is determined to not be highly effective no longer qualifies for hedge accounting and any gain or loss is recognized immediately into earnings. Amount reclassified into earnings are included in interest expense in the Consolidated Statement of Income. Derivatives Not Designated as Hedging Instruments We act as an interest rate or foreign exchange swap counterparty for certain commercial borrowers in the normal course of servicing our customers, which are accounted for at fair value. We manage our exposure to such interest rate or foreign exchange swaps by entering into corresponding and offsetting interest rate swaps with third parties that mirror the terms of the swaps we have with the commercial borrowers. These positions (referred to as “customer swaps”) directly offset each other and our exposure is the fair value of the derivatives due to changes in credit risk of our commercial borrowers and third parties. Customer swaps are recorded within other assets or other liabilities on the consolidated statement of financial condition at their estimated fair value. Changes to the fair value of assets and liabilities arising from these derivatives are included, net, in other operating income in the Consolidated Statement of Income. We enter into interest rate lock commitments for residential mortgage loans which commit us to lend funds to a potential borrower at a specific interest rate within a specified period of time. Interest rate lock commitments that relate to the origination of mortgage loans that will be held-for-sale are considered derivative financial instruments under applicable accounting guidance. Interest rate lock commitments on loans held-for-sale are carried at fair value in other assets on the consolidated statement of financial condition. Northwest sells loans to the secondary market on a mandatory or best efforts basis. The loans sold on a mandatory basis commit us to deliver a specific principal amount of mortgage loans to an investor at a specified price, by a specified date, or the commitment must be paired off. These forward commitments entered into on a mandatory delivery basis meet the definition of a derivative financial instrument. All closed loans to be sold on a mandatory delivery basis are classified as held-for-sale on the Consolidated Statement of Financial Condition. Changes to the fair value of the interest rate lock commitments and the forward commitments are recorded in mortgage banking income in the Consolidated Statements of Income. We enter into risk participation agreements with financial institution counterparties for interest rate swaps related to loans in which we are a participant. The risk participation agreements provide credit protection to the financial institution should the borrower fail to perform on its interest rate derivative contract with the financial institution. These risk participation agreements are recorded within other liabilities on the Consolidated Statement of Financial Condition at their estimated fair value. Changes to the fair value of the the risk participation agreements are included in other operating income in the Consolidated Statement of Income.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Northwest Bancshares, Inc. (the “Company” or “NWBI”), a Maryland corporation headquartered in Columbus, Ohio, is a bank holding company regulated by the Board of Governors of the Federal Reserve System (“FRB”). The primary activity of the Company is the ownership of all of the issued and outstanding common stock of Northwest Bank, a Pennsylvania-chartered savings bank (“Northwest”). Northwest is regulated by the Federal Deposit Insurance Corporation (“FDIC”) and the Pennsylvania Department of Banking. Northwest operates 142 community-banking offices throughout Pennsylvania, Western New York, Eastern Ohio, and Indiana. The accompanying unaudited Consolidated Financial Statements include the accounts of the Company and its subsidiary, Northwest, and Northwest’s subsidiaries Northwest Capital Group, Inc., Great Northwest Corporation, and MutualFirst Interest Company, Inc. The unaudited Consolidated Financial Statements have been prepared in accordance with United States generally accepted accounting principles for interim financial information and with the instructions for Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information or footnotes required for complete annual financial statements. In the opinion of management, all adjustments necessary for the fair presentation of the Company’s financial position and results of operations have been included. The Consolidated Financial Statements have been prepared using the accounting policies described in the financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022 updated, as required, for any new pronouncements or changes.
Reclassifications	Certain items previously reported have been reclassified to conform to the current year’s reporting format. These reclassifications had no effect on the reported results of operations. An adjustment has been made to the Consolidated Statements of Income and Consolidated Statements of Cash Flows for the quarter and six months ended June 30, 2022, to reclassify the provision for credit losses - unfunded commitments, previously presented in other expense, to provide additional transparency to financial statement users.
Income Taxes - Uncertain Tax Positions	Income Taxes-Uncertain Tax Positions Accounting standards prescribe a comprehensive model for how a company should recognize, measure, present and disclose in its financial statements uncertain tax positions that the company has taken or expects to take on a tax return. A tax benefit from an uncertain position may be recognized only if it is “more likely than not” that the position is sustainable, based on its technical merits. The tax benefit of a qualifying position is the largest amount of tax benefit that is greater than 50% likely of being realized upon ultimate settlement with a taxing authority having full knowledge of all relevant information. We had $473,000 of liability for unrecognized tax benefits as of both June 30, 2023 and December 31, 2022. We recognize interest accrued related to: (1) unrecognized tax benefits in other expenses and (2) refund claims in other operating income. We recognize penalties (if any) in other expenses. We are subject to audit by the Internal Revenue Service and any state in which we conduct business for the tax periods ended December 31, 2022, 2021, 2020 and 2019.
Recently Adopted Accounting Standards	Recently Adopted Accounting Standards In March 2022, the Financial Accounting Standards Board ( “ FASB ” ) issued Accounting Standards Update ( “ ASU ” ) No. 2022-02, “Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosure.” This ASU eliminates the accounting guidance for troubled debt restructurings ( “ TDRs ” ), while enhancing disclosure requirements for certain loan modifications when a borrower is experiencing financial difficulty. This ASU also requires the disclosure of current period gross write-offs by year for origination for financing receivables. This guidance is effective for annual periods beginning after December 15, 2022, including interim periods within those years, with early adoption permitted. This ASU is applied prospectively to modifications and write-offs beginning on the first day of the fiscal year of adoption. An entity may elect to adopt a modified retrospective transition method on the recognition and measurement of the TDR guidance. We adopted ASU 2022-02 using a modified retrospective transition approach related to the recognition and measurement of the TDR guidance and on a prospective basis for modification and write-offs. As a result, the Company was not required to adjust its comparative period financial information for effects of the standard or make the new required ASU 2022-02 disclosure for periods before the date of adoption (i.e. January 1, 2023). This change did not have a material effect on our consolidated financial statements. In March 2020, the FASB issued Accounting Standards Update (“ASU”) No. 2020-04, “ Facilitation of the Effects of Reference Rate Reform on Financial Reporting .” This ASU provides temporary optional guidance on contract modifications and hedge accounting to ease the financial reporting burdens of the expected market transition from LIBOR and other interbank offered rates to alternative reference rates. The guidance provides expedients and exceptions for applying GAAP to transactions affected by reference rate reform if certain criteria are met. The amendments primarily include contract modifications and hedge accounting, as well as providing a one-time election for the sale or transfer of debt securities classified as held-to-maturity. This guidance was effective as of March 12, 2020 through December 31, 2022. In December 2022, the FASB issued ASU No. 2022-06, “Reference Rate Reform (Topic 848): Deferral of the Sunset Date to Topic 848”. This guidance extends the guidance of ASU 2022-04 from December 31, 2022 to December 31, 2024. In January 2021, the FASB issued ASU No. 2021-01, “Reference Rate Reform.” This ASU provides amendments, which are elective, and apply to all entities that have derivative instruments that use an interest rate for margining, discounting or contract price alignment of certain derivative instruments that are modified as a result of the reference rate reform. This ASU is effective upon issuance through December 31, 2024, and can be adopted at any time during this period.
