Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	1. Basis of Presentation Premier Financial Corp. (“Premier” or the “Company”) is a financial holding company that conducts business through its wholly-owned subsidiaries, Premier Bank (the "Bank"), and PFC Capital, LLC (“PFC Capital”). All significant intercompany transactions and balances are eliminated in consolidation. Premier’s stock is traded on the NASDAQ Global Select Market under the ticker PFC. On July 26, 2024 , Premier and Wesbanco announced the signing of the definitive Merger Agreement under which Premier will merge into Wesbanco in a stock-for-stock transaction. Refer to Note 17. The Bank is primarily engaged in community banking. It attracts deposits from the general public through its offices and website, and uses those and other available sources of funds to originate residential real estate loans, commercial real estate loans, commercial loans, home improvement and home equity loans and consumer loans. In addition, the Bank invests in U.S. Treasury and federal government agency obligations, obligations of states and political subdivisions, mortgage-backed securities ("MBS") that are issued by federal agencies, collateralized mortgage obligations (“CMOs”), and corporate bonds. The Bank’s deposits are insured by the Federal Deposit Insurance Corporation (“FDIC”). The Bank is a member of the Federal Home Loan Bank (“FHLB”) System. PFC Capital was formed as an Ohio limited liability company in 2016 for the purpose of providing mezzanine funding for customers. Mezzanine loans are offered by PFC Capital to customers in the Company’s market area and are expected to be repaid from the cash flow from operations of the business. First Insurance Group of the Midwest, Inc. ("First Insurance") is a wholly-owned subsidiary of Premier that conducted business as an insurance agency throughout Premier’s markets. First Insurance offered property and casualty insurance, life insurance and group health insurance. On June 30, 2023, the Company completed the sale of substantially all of the assets (including $ 24.7 million of goodwill and intangibles) of First Insurance to Risk Strategies Corporation (“Buyer”). Consideration included a combination of cash and a subordinated note resulting in net cash received of $ 47.4 million after certain transaction costs at closing, the assumption of certain leases, and contingent consideration subject to certain performance criteria by the Buyer to be determined after the year ended December 31, 2026. The Company recorded a pre-tax gain on sale of $ 36.3 million, transaction costs of $ 3.7 million and taxes of $ 8.5 million for a $ 24.1 million increase to equity in 2023. The Company tests goodwill at least annually and, more frequently, if events or changes in circumstances indicate that it may be more likely than not that there is a possible impairment. Due to the Company’s signing of the definitive agreement for the merger transaction with Wesbanco, the Company conducted a quantitative interim goodwill impairment assessment at September 30, 2024. The impairment assessment compares the fair value of identified reporting unit with their carrying amount (including goodwill). If the carrying amount of a reporting unit exceeds its fair value, an impairment loss is recognized in an amount equal to the excess. The Company's interim assessment estimated fair value on income and market approaches. The income approach incorporated a discounted cash flow model that involves management assumptions and consideration of future economic forecasts available. The market approach incorporates a combination of price to book value and price to earnings, adjusted based on companies similar to the reporting unit and adjusted for selected multiples, along with a control premium based on a review of transactions in the banking industry. Results of the interim assessment indicated no goodwill impairment as of September 30, 2024. The Company will continue to monitor its goodwill for possible impairment. The consolidated condensed statement of financial condition at December 31, 2023, was derived from the audited financial statements at that date, which were included in Premier’s 2023 Form 10-K. The accompanying consolidated condensed financial statements as of September 30, 2024, and for the three and nine months ended September 30, 2024 and 2023 have been prepared by the Company without audit and do not include information or footnotes necessary for the complete presentation of financial condition, results of operations, and cash flows in conformity with accounting principles generally accepted in the United States (“GAAP”). These consolidated condensed financial statements should be read in conjunction with the financial statements and notes thereto included in the 2023 Form 10-K. However, in the opinion of management, all adjustments, consisting of only normal recurring items, necessary for the fair presentation of the financial statements have been made. The results for the three and nine months ended September 30, 2024 , are not necessarily indicative of the results that may be expected for the entire year.

Accounting Policies [Abstract]
Significant Accounting Policies	2. Significant Accounting Policies Accounting Standards Update ("ASU") ASU No. 2023-06, Disclosure Improvements – Codification Amendments in Response to the Securities and Exchange Commission’s ("SEC") Disclosure Update and Simplification Initiative: On October 9, 2023, the Financial Accounting Standards Board (the "FASB") issued ASU 2023-06 “Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative,” which incorporates 14 of the 27 disclosures referred by the SEC in Release No. 33-10532, “Disclosure Update and Simplification,” that was issued August 17, 2018. The changes modify the disclosure or presentation requirements of a variety of topics including statement of cash flows, accounting changes and error corrections, earnings per share, interim reporting, commitments, debt, equity, derivatives and hedging, and secured borrowing and collateral. For entities subject to the SEC’s existing disclosure requirements and for entities required to file or furnish financial statements with or to the SEC in preparation for the sale of or for purposes of issuing securities that are not subject to contractual restrictions on transfer, the effective date for each amendment is the date on which the SEC removes that related disclosure from its rules. For all other entities, the amendments will be effective two years later. If the SEC has not removed the related disclosure from its regulations by June 30, 2027, the amendments will be removed from the codification and not become effective for any entity. This ASU is not expected to have a material effect on the Company’s consolidated condensed financial statements. ASU No. 2023-07, Segment Reporting (Topic 280) – Improvements to Reportable Segment Disclosures: On November 27, 2023, the FASB issued ASU 2023-07 “Segment Reporting (Topic 820): Improvements to Reportable Segment Disclosure,” which requires public entities to disclose significant expense categories and amounts for each reportable segment, an amount for and description of the composition of “other segment items,” the title and position of the entity’s Chief Operating Decision Maker (the "CODM") and explanation of how the CODM uses the reported measures of profit or loss to assess segment performance, and – on an interim basis – certain segment-related disclosures that previously were required only on an annual basis. This ASU clarifies that entities with a single reportable segment are subject to both new and existing segment reporting requirements and that an entity is permitted to disclose multiple measures of segment profit or loss, provided that certain criteria are met. The amendments are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. Entities must adopt the changes to the segment reporting guidance on a retrospective basis. This ASU is not expected to have a material effect on the Company’s consolidated condensed financial statements. ASU No. 2023-09, Income Taxes (Topic 740) – Improvements to Income Tax Disclosures: On December 14, 2023, the FASB issued ASU 2023-09 “Income Taxes (Topic 740): Improvements to Income Tax Disclosures,” to address requests for improved income tax disclosures from investors, lenders, creditors and other allocators of capital that use the financial statements to make capital allocation decisions. This ASU is intended to improve the transparency of tax disclosures by requiring (1) consistent categories and greater disaggregation of information in the rate reconciliation and (2) income taxes paid disaggregated by jurisdiction, in addition to certain other amendments intended to improve the effectiveness of income tax disclosures. For public business entities, this ASU is effective for annual periods beginning after December 15, 2024. For other entities, this ASU is effective for annual periods beginning after December 15, 2025. Early adoption is permitted for annual financial statements that have not yet been issued or made available for issuance. This ASU is not expected to have a material effect on the Company’s consolidated condensed financial statements. SEC Final Rules Not Yet Adopted The Enhancement and Standardization of Climate-Related Disclosures for Investors: On March 6, 2024, the SEC approved the final rule for these disclosures, requiring registrants to provide information about climate-related risks that materially impact or are reasonably likely to materially impact a registrant's strategy, results of operations, or financial condition. The rule applies to all SEC reporting companies and may significantly increase reporting costs and complexities, including increased data collection and development of significant internal processes and controls. The final rule includes a phased-in compliance period, effective for the Company for the fiscal year ending December 31, 2025. On March 15, 2024, the U.S. Court of Appeals granted an administrative stay of the climate-related disclosure rules recently adopted by the SEC.

Fair Value Disclosures [Abstract]
Fair Value	3. Fair Value FASB ASC Topic 820, Fair Value Measurement, defines fair value as 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 (an exit price). A fair value measurement assumes that the transaction to sell the asset or transfer the liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability. The price in the principal (or most advantageous) market used to measure the fair value of the asset or liability shall not be adjusted for transaction costs. An orderly transaction is a transaction that assumes exposure to the market for a period prior to the measurement date to allow for marketing activities that are usual and customary for transactions involving such assets and liabilities; it is not a forced transaction. Market participants are buyers and sellers in the principal market that are (i) independent, (ii) knowledgeable, (iii) able to transact and (iv) willing to transact. FASB ASC Topic 820 requires the use of valuation techniques that are consistent with the market approach, the income approach and/or the cost approach. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets and liabilities. The income approach uses valuation techniques to convert future amounts, such as cash flows or earnings, to a single present amount on a discounted basis. The cost approach is based on the amount that currently would be required to replace the service capacity of an asset (replacement cost). Valuation techniques should be consistently applied. Inputs to valuation techniques refer to the assumptions that market participants would use in pricing the asset or liability. Inputs may be observable, meaning those that reflect the assumptions market participants would use in pricing the asset or liability developed based on the best information available. In that regard, FASB ASC Topic 820 established a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows: • Level 1 : Quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. • Level 2 : Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These might include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (such as interest rates, prepayment speeds, credit risks, etc.) or inputs that are derived principally from or corroborated by market data by a correlation or other means. • Level 3 : Unobservable inputs for the asset or liability and that are significant to the fair value of assets and liabilities (i.e., allowing for situations in which there is little or no market activity for the asset or liability at the measurement date). A description of the valuation methodologies used for instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below. Available-for-sale securities – Securities classified as available for sale are generally reported at fair value utilizing Level 2 inputs where the Company obtains fair value measurements from an independent pricing service that uses matrix pricing, which is a mathematical technique widely used in the industry to value debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities’ relationship to other benchmark quoted securities (Level 2 inputs). The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows and the bonds’ terms and conditions, among other things. Securities in Level 2 include U.S. federal government agencies, MBS, asset-backed securities ("ABS"), corporate bonds and municipal securities. Securities in Level 1 include U.S. treasuries. Equity securities – These securities are reported at fair value utilizing Level 1 inputs where the Company obtains fair value measurements from a broker. Loans held for sale, carried at fair value – The Company has elected the fair value option for all loans held for sale originated after January 31, 2020. The fair value of conventional loans held for sale is determined using the current 15-day forward contract price for either 15 or 30 year conventional mortgages (Level 2). The fair value of permanent construction loans held for sale is determined using the current 5-day forward contract price for 15 or 30 years conventional mortgages which is then adjusted for unobservable market data such as estimated fall out rates and estimated time from origination to completion of construction (Level 3). Collateral dependent loans – Fair values for individually analyzed collateral dependent loans are generally based on appraisals obtained from licensed real estate appraisers and in certain circumstances consideration of offers obtained to purchase properties prior to foreclosure. Appraisals for commercial real estate generally use three methods to derive value: cost, sales or market comparison and income approach. The cost method bases value on the cost to replace the current property. Value of market comparison approach evaluates the sales price of similar properties in the same market area. The income approach considers net operating income generated by the property and an investor’s required return. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available. Comparable sales adjustments are based on known sales prices of similar type and similar use properties and duration of time that the property has been on the market to sell. Such adjustments made in the appraisal process are typically significant and result in a Level 3 classification of the inputs for determining fair value. Real estate held for sale – Assets acquired through or instead of loan foreclosure are initially recorded at fair value less costs to sell when acquired, establishing a new cost basis. These assets are then reviewed monthly by members of the asset review committee for valuation changes and are accounted for at lower of cost or fair value less estimated costs to sell. Fair value is commonly based on recent real estate appraisals which may utilize a single valuation approach or a combination of approaches including cost, comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available. Such adjustments may be significant and typically result in a Level 3 classification of the inputs for determining fair value. Appraisals for both individually analyzed collateral-dependent loans and other real estate owned ("OREO") are performed by certified general appraisers (for commercial properties) or certified residential appraisers (for residential properties) whose qualifications and licenses have been reviewed and verified by the Company. Once received, a member of the Company’s asset quality or collections department reviews the assumptions and approaches utilized in the appraisal. Appraisal values are discounted from 0 % to 30 % to account for other factors that may impact the value of collateral. In determining the value of individually analyzed collateral dependent loans and OREO, significant unobservable inputs may be used, which include but are not limited to physical condition of comparable properties sold, net operating income generated by the property and investor rates of return. Mortgage servicing rights – On a quarterly basis, mortgage servicing rights are evaluated for impairment based upon the fair value of the rights as compared to the carrying amount. If the carrying amount of an individual tranche exceeds fair value, impairment is recorded on that tranche so that the servicing asset is carried at fair value. Fair value is determined at a tranche level based on a model that calculates the present value of estimated future net servicing income. The valuation model utilizes assumptions that market participants would use in estimating future net servicing income and are validated against available market data (Level 2). Mortgage banking derivative – The fair value of mortgage banking derivatives is evaluated monthly based on derivative valuation models using quoted prices for similar assets adjusted for specific attributes of the commitments and other observable market data at the valuation date (Level 2). Interest rate swaps – The Company periodically enters into interest rate swap agreements with its commercial customers who desire a fixed rate loan term that is longer than the Company is willing to extend. The Company then enters into a reciprocal swap agreement with a third party that offsets the interest rate risk from the interest rate swap extended to the customer. The interest rate swaps are derivative instruments which are carried at fair value on the statement of financial condition. The Company uses an independent third party to perform a market valuation analysis for both swap positions (Level 2). Cash flow and fair value hedge derivatives – The Company periodically enters into cash flow and fair value hedge derivative instruments to hedge the risk of variability in cash flows on the Company's floating rate loan pool, fixed rate mortgage loan pool and FHLB advances. The Company uses an independent third party to perform a market valuation analysis for these derivatives (Level 2). The following table summarizes the financial assets measured at fair value on a recurring basis segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value: Assets and Liabilities Measured on a Recurring Basis September 30, 2024 Level 1 Level 2 Level 3 Total (In Thousands) Assets: Available for sale securities: Obligations of U.S. federal government corporations and $ — $ 104,507 $ — $ 104,507 Mortgage-backed securities — 175,291 — 175,291 Collateralized mortgage obligations — 350,109 — 350,109 Asset-backed securities — 243,817 — 243,817 Corporate bonds — 64,806 — 64,806 Obligations of state and political subdivisions — 207,351 — 207,351 US Treasuries 50,377 — — 50,377 Equity securities 5,970 — — 5,970 Loans held for sale, at fair value — 17,623 103,988 121,611 Interest rate swaps — 3,000 — 3,000 Liabilities: Interest rate swaps — 3,058 — 3,058 Cash flow/fair value hedge derivatives — 31,068 — 31,068 Mortgage banking derivatives - liability — 443 — 443 December 31, 2023 Level 1 Level 2 Level 3 Total Fair (In Thousands) Assets: Available for sale securities: Obligations of U.S. government corporations and agencies $ — $ 101,598 $ — $ 101,598 Mortgage-backed securities — 156,508 — 156,508 Collateralized mortgage obligations — 235,767 — 235,767 Asset-backed securities — 136,980 — 136,980 Corporate bonds — 62,420 — 62,420 Obligations of states and political subdivisions — 204,258 — 204,258 US Treasuries 49,177 — — 49,177 Equity securities 5,773 — — 5,773 Loans held for sale, at fair value — 14,397 131,244 145,641 Interest rate swaps — 2,867 — 2,867 Cash flow / Fair value hedge derivatives — 299 — 299 Liabilities: Interest rate swaps — 2,867 — 2,867 Cash flow / Fair value hedge derivatives — 35,392 — 35,392 Mortgage banking derivatives - liability — 4,750 — 4,750 The following table presents a reconciliation of assets that are measured at fair value on a recurring basis using significant unobservable inputs (Level 3) for the three and nine months ended September 30, 2024 and 2023 .

These loans are intended for sale and the Company believes that fair value is the best indicator of the resolution of these loans. Interest income is recorded based on the contractual terms of the loan and in accordance with the Company’s policies. The aggregate fair value of the residential mortgage loans held for sale at September 30, 2024 and December 31, 2023 was $ 17.6 million and $ 14.4 million, respectively, and they had a contractual balance of $ 17.6 million and $ 14.7 million, respectively, for these same periods. The difference between the fair value and the contractual balance is recorded in gains and losses on the sale of loans held for sale. For the three and nine months ended September 30, 2024 , $ 260,000 and $ 228,000 , respectively, was recorded in gains (losses) on the sale of loans held for sale for the change in fair value. For the three and nine months ended September 30, 2023 , $ 83,000 and $ 473,000 , respectively, was recorded in gains (losses) on the sale of loans held for sale for the change in fair value. The aggregate fair value of the permanent construction loans held for sale at September 30, 2024 and December 31, 2023 , was $ 104.0 million and $ 131.2 million, respectively, and they had a contractual balance of $ 98.7 million and $ 133.1 million, respectively, for these same periods. The difference between the fair value and the contractual balance is recorded in gains and losses on the sale of loans held for sale. For the three and nine months ended September 30, 2024 , $ 7.9 million and $ 5.6 million, respectively, was recorded in gains (losses) on the sale of loans held for sale for the change in fair value. For the three and nine months ended September 30, 2023 , $ 5.9 million and $ 874,000 , respectively, was recorded in gains (losses) on the sale of loans held for sale for the change in fair value. The following table summarizes the financial assets measured at fair value on a non-recurring basis segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value: Assets and Liabilities Measured on a Non-Recurring Basis September 30, 2024 Level 1 Level 2 Level 3 Total Fair (In Thousands) Individually analyzed loans Commercial real estate $ — $ — $ 7,796 $ 7,796 Commercial — — 24,694 24,694 Mortgage servicing rights — 2,346 — 2,346 December 31, 2023 Level 1 Level 2 Level 3 Total Fair (In Thousands) Individually analyzed loans Commercial real estate $ — $ — $ 3,425 $ 3,425 Commercial — — 6,164 6,164 Mortgage servicing rights — 2,744 — 2,744 For Level 3 assets and liabilities measured at fair value on a non-recurring basis as of September 30, 2024, the significant unobservable inputs used in the fair value measurements were as follows: Fair Valuation Unobservable Range of Weighted (Dollars in Thousands) Individually analyzed Loans- $ 32,490 Appraisals which utilize sales comparison, net income and cost approach Discounts for collection issues and changes in market conditions 10 - 50 % 39.72 % For Level 3 assets and liabilities measured at fair value on a non-recurring basis as of December 31, 2023, the significant unobservable inputs used in the fair value measurements were as follows: Fair Valuation Unobservable Range of Weighted (Dollars in Thousands) Individually analyzed Loans- $ 9,589 Appraisals which utilize sales comparison, net income and cost approach Discounts for collection issues and changes in market conditions 10 - 50 % 27.60 % Fair value of financial instruments Much of the information used to arrive at “fair value” is highly subjective and judgmental in nature and therefore the results may not be precise. Subjective factors include, among other things, estimated cash flows, risk characteristics and interest rates, all of which are subject to change. With the exception of investment securities, the Company’s financial instruments are not readily marketable and market prices do not exist. Since negotiated prices for the instruments, which are not readily marketable, depend greatly on the motivation of the buyer and seller, the amounts that will actually be realized or paid per settlement or maturity of these instruments could be significantly different. The carrying amount of cash and cash equivalents, as a result of their short-term nature, is considered to be equal to fair value and are classified as Level 1. It was not practicable to determine the fair value of FHLB stock due to restrictions placed on its transferability. The Company’s loans were valued on an individual basis, with consideration given to the loans’ underlying characteristics, including account types, remaining terms (in months), annual interest rates or coupons, interest types, past delinquencies, timing of principal and interest payments, current market rates, loss exposures, and remaining balances. The model utilizes a discounted cash flow (“DCF”) approach to estimate the fair value of the loans using assumptions for the coupon rates, remaining maturities, prepayment speeds, projected default probabilities, losses given defaults, and estimates of prevailing discount rates. The DCF approach models the credit losses directly in the projected cash flows. The model applies various assumptions regarding credit, interest, and prepayment risks for the loans based on loan types, payment types and fixed or variable classifications. The estimated fair value of individually analyzed loans is based on the fair value of the collateral, less estimated cost to sell, or the present value of the loan’s expected future cash flows (discounted at the loan’s effective interest rate). All individually analyzed loans are classified as Level 3 within the valuation hierarchy. The fair value of non-interest bearing deposits are considered equal to the amount payable on demand at the reporting date (i.e. carrying value) and are classified as Level 1. The fair value of savings, checking and certain money market accounts are equal to their carrying amounts and are a Level 1 classification. Fair values of fixed rate certificates of deposit are estimated using a DCF calculation that applies interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities on time deposits resulting in a Level 2 classification. The carrying value of notes payable, as a result of their short-term nature, is considered to be equal to fair value and are classified as Level 1. The carrying value of floating rate subordinated debentures was considered to be the carrying value as the debt is floating rate and can be prepaid at any time without penalty. The carrying value of fixed rate subordinated debt is estimated using a DCF calculation that applies interest rates currently being offered in the market to the expected maturity of the debt resulting in a Level 2 classification. FHLB advances with maturities greater than 90 days are valued based on a DCF analysis, using interest rates currently being quoted for similar characteristics and maturities resulting in a Level 2 classification. The cost or value of any call or put options is based on the estimated cost to settle the option at September 30, 2024. Subordinated debt is valued utilizing the coupon rate, discount rate, weighted average life and duration. This debt is classified as Level 3. The carrying amount of advance payments by borrowers, as a result of their short-term nature, is considered to be equal to fair value and are classified as Level 1.

Share-Based Payment Arrangement [Abstract]
Stock Compensation Plans	4. Stock Compensation Plans Premier has established equity-based compensation plans for its directors and employees. On February 27, 2018, the Board adopted, and the shareholders approved at the 2018 Annual Shareholders Meeting, the Premier Financial Corp. 2018 Equity Incentive Plan (the “2018 Equity Plan”). The 2018 Equity Plan replaced all existing plans, although the Company’s former equity plans remain in existence to the extent there were outstanding grants thereunder at the time the 2018 Equity Plan was approved. In addition, as a result of the Company's merger (the "UCFC Merger") with United Community Federal Corp. ("UCFC"), Premier assumed certain outstanding stock options granted under UCFC’s Amended and Restated 2007 Long-Term Incentive Plan (the “UCFC 2007 Plan”) and UCFC’s 2015 Long Term Incentive Plan, which has since been renamed as the “Premier Financial Corp. 2015 Long Term Incentive Plan” (the “2015 Plan”). Premier also assumed the shares available for future issuance under the 2015 Plan as of the effective date of the UCFC Merger, with appropriate adjustments to the number of shares available to reflect the UCFC Merger. The stock options assumed from UCFC in the UCFC Merger remain subject to the terms of the 2015 Plan, but became exercisable solely to purchase shares of Premier, with appropriate adjustments to the number of shares subject to the assumed stock options and the exercise price of such stock options. Besides certain options previously issued under the First Defiance Financial Corp. 2010 Equity Incentive Plan, all awards currently outstanding are issued under the 2018 Equity Plan or the 2015 Plan. The 2018 Equity Plan and the 2015 Plan were each amended and restated in February 2022 to align certain administrative components of the plans in addition to enhancing certain governance components. New awards will be made under either the 2018 Equity Plan or the 2015 Plan as the Company determines. The 2018 Equity Plan allows for issuance of up to 900,000 common shares through the award of options, restricted stock, stock, stock appreciation rights, or other stock-based awards. The 2015 Plan allows for the issuance of up to 1.2 million common shares, as adjusted for the UCFC Merger, through the award of options, stock, restricted stock, stock units, stock appreciation rights, or performance stock awards. Beginning in 2023, directors were able to elect to receive stock in lieu of cash for their director fees. In the first nine months of 2024 , the Company did no t issue any shares or recognize any expense for shares. In the first nine months of 2023 , the Company recognized $ 60,000 in expense for 2,930 shares that were issued to directors in lieu of cash fees. The Company maintains Long-Term Equity Incentive Plans (each, an "LTIP") for select members of management (the "Executive LTIP") and a Key Employee and Commercial Lender Plan (the "Key Plan"). Under the Executive LTIP, participants may earn between 20 % to 50 % of their salary for potential payout in the form of (1) equity awards based on the achievement of certain corporate performance targets over a three-year period and (2) beginning in 2023, restricted stock awards (“RSAs”). The Company granted 83,148 performance stock units ("PSUs") to the participants under the Executive LTIP during the first nine months of 2024 , which represents the maximum target award. The value of PSU awards issued in 2022, 2023 and 2024 under the Executive LTIP will be determined individually at the end of each respective 36 month performance period ending December 31. The benefits earned under these PSUs will be paid out in equity in the first quarter following the end of the performance period. The participants will receive all or a portion of the award if their employment is terminated by the Company without cause, by the participant in certain situations, or by death, disability or retirement of the participant. The RSAs issued under the Executive LTIP vest incrementally over three years, being fully vested upon the third anniversary of the grant date. The Company granted 28,702 RSAs under the Executive LTIP in the first nine months of 2024. The maximum amount of compensation expense that may be earned for the PSUs at September 30, 2024 is approximately $ 5.7 million in the aggregate. However, the estimated expense that is expected to be earned as of September 30, 2024 is $ 3.8 million, of which $ 2.7 million was unrecognized at September 30, 2024 , and will be recognized over the remaining performance periods. A reduction of expense of $ 91,000 and expense of $ 245,000 were recorded during the three and nine months ended September 30, 2024 , respectively, compared to an expense of $ 33,000 and a reduction in expense of $ 506,000 for the three and nine months ended September 30, 2023, respectively. Beginning in 2022, under the Key Plan, the participants were granted RSAs based upon the achievement of certain targets in the prior year. Prior to 2022, restricted stock units ("RSUs") were issued to participants under the same plan. The participants can earn from 5 % to 10 % of their salary in RSAs or RSUs that vest three years from the date of grant. The Company granted 31,139 RSAs and 25,044 RSAs in the first nine months of 2024 and 2023, respectively, as a payout under the Key Plan. In the nine months ended September 30, 2024 , the Company also granted 9,471 in discretionary RSAs and 24,768 RSAs to directors that vest over a one to three-year time period. Compensation expense is recognized over the performance or vesting period. Total expense of $ 560,000 and $ 1.6 million was recorded during the three and nine months ended September 30, 2024 , respectively, compared to expense of $ 495,000 and $ 1.4 million for the three and nine months ended September 30, 2023 , respectively. Approximately $ 1.7 million and $ 1.9 million is included within other liabilities at September 30, 2024 and December 31, 2023, respectively, related to the cash portion of the Company's Short-Term Incentive Plans. The following table sets forth Premier's performance and restricted stock activity during the nine months ended September 30, 2024: PSUs RSUs RSAs Unvested Shares Shares Weighted- Shares Weighted- Shares Weighted- Unvested at January 1, 2024 217,562 $ 28.75 18,625 $ 29.52 153,779 $ 25.49 Granted 82,737 19.43 — — 94,080 19.88 Vested ( 23,245 ) 30.08 ( 18,625 ) 29.52 ( 42,047 ) 23.02 Forfeited ( 57,688 ) 30.17 — — ( 3,975 ) 23.90 Unvested at September 30, 2024 219,366 $ 24.72 — $ — 201,837 $ 23.42 As of September 30, 2024 , 28,175 options to acquire Premier shares were outstanding at option prices based on the market value of the underlying shares on the date the options were granted. All options expire ten years from the date of grant. Vested options of retirees expire on the earlier of the scheduled expiration date or one year after the retirement date. The fair value of each option award is estimated on the date of grant using the Black-Scholes model. Expected volatilities are based on historical volatilities of the Company’s common shares. The Company uses historical data to estimate option exercise and post-vesting termination behavior. The expected term of options granted is based on historical data and represents the period of time that options granted are expected to be outstanding, which takes into account that the options are not transferable. The risk-free interest rate for the expected term of the option is based on the U.S. Treasury yield curve in effect at the time of the grant. There were no options granted during the nine months ended September 30, 2024 and 2023. Following is stock option activity under the plans during the nine months ended September 30, 2024: Options Weighted Weighted Aggregate Options outstanding, January 1, 2024 28,175 $ 23.18 Forfeited or cancelled — — Exercised — — Granted — — Options outstanding, September 30, 2024 28,175 $ 23.18 2.51 $ 55,196 Exercisable at September 30, 2024 28,175 $ 23.18 2.51 $ 55,196 As of September 30, 2024 , there was a de minimus amount of total unrecognized compensation costs related to unvested stock options granted under the Company’s equity plans. The cost is expected to be recognized over a weighted-average period of one month .

Earnings Per Share [Abstract]
Earnings Per Common Share	6. Earnings Per Common Share Basic earnings per share are calculated using the two-class method. The two-class method is an earnings allocation formula under which earnings per share is calculated from common stock and participating securities according to dividends declared and participation rights in undistributed earnings. Under this method, all earnings distributed and undistributed, are allocated to participating securities and common shares based on their respective rights to receive dividends. Unvested share-based payment awards that contain non-forfeitable rights to dividends are considered participating securities (i.e., unvested restricted stock), not subject to performance based measures. The following table sets forth the computation of basic and diluted earnings per common share: Three Months Ended Nine Months Ended 2024 2023 2024 2023 (In Thousands, except per share data) Basic Earnings Per Share: Net income available to common shareholders $ 16,665 $ 24,687 $ 50,630 $ 91,227 Less: income allocated to participating securities 90 40 261 133 Net income allocated to common shareholders 16,575 24,647 50,369 91,094 Weighted average common shares outstanding including 35,840 35,731 35,815 35,701 Less: Participating securities 148 18 141 11 Average common shares 35,692 35,713 35,674 35,690 Basic earnings per common share $ 0.46 $ 0.69 $ 1.41 $ 2.55 Diluted Earnings Per Share: Net income allocated to common shareholders $ 16,575 $ 24,647 $ 50,369 $ 91,094 Weighted average common shares outstanding for basic earnings 35,692 35,713 35,674 35,690 Add: Dilutive effects of stock options and restricted stock units 45 80 104 79 Average shares and dilutive potential common shares 35,737 35,793 35,778 35,769 Diluted earnings per common share $ 0.46 $ 0.69 $ 1.41 $ 2.55 There were no shares for the three and nine months ended September 30, 2024 or 2023 that were excluded from the diluted earnings per common share calculation as anti-dilutive.

Expected maturities will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. For purposes of the maturity table, MBS, CMOs and ABS, which are not due at a single maturity date, have not been allocated over the maturity groupings. These securities may mature earlier than their weighted-average contractual maturities because of principal prepayments.

For the three and nine months ended September 30, 2023 , the Company had no realized gains or losses and $ 27,000 in realized gains, respectively, from the sale of investment securities. It is expected that the securities would not be settled at less than the amortized cost of the Company's investment because the decline in fair value is attributable to changes in interest rates and relative spreads and not credit quality. Management does not intend to sell these investments and it is not expected that the Company will be required to sell the investments before recovery of its amortized cost basis. Quarterly, the Company evaluates if any security has a fair value less than its amortized cost. Once these securities are identified, in order to determine whether a decline in fair value resulted from a credit loss or other factors, the Company performs further analysis as outlined below: • Review the extent to which the fair value is less than the amortized cost and observe the security’s lowest credit rating as reported by third-party credit ratings companies. • Any security that has a loss rate greater than 3 %, credit rating below investment grade or not rated by a third-party credit ratings company would be subjected to additional analysis that may include, but is not limited to: changes in market interest rates, changes in securities credit ratings, security type, service area economic factors, financial performance of the issuer/or obligor of the underlying issue and third-party guarantee. • If the Company determines that a credit loss exists, the credit portion of the allowance will be measured using a DCF analysis using the effective interest rate as of the security’s purchase date. The amount of credit loss the Company records will be limited to the amount by which the amortized cost exceeds the fair value. As of September 30, 2024, management determined that no credit loss exists and that the unrealized losses are due to the increased interest rate environment. At September 30, 2024 and December 31, 2023 , the Company held preferred and common stock of various bank holding companies totaling $ 5.9 million and $ 5.8 million, respectively. During the three and nine months ended September 30, 2024 , a realized gain of $ 410,000 and $ 197,000 , respectively, was recorded within gain (loss) on equity securities on the Consolidated Condensed Statements of Income. During the three and nine months ended September 30, 2023 , a realized gain of $ 256,000 and a realized loss of $ 1.1 million, respectively, was recorded within gain (loss) on equity securities on the Consolidated Condensed Statements of Income.

Occasionally, the Company modifies loans by providing principal forgiveness on certain of its real estate loans. When principal forgiveness is provided, the amortized cost basis of the loan is written off against the allowance for credit losses. The amount of the principal forgiveness is deemed to be uncollectible; therefore, that portion of the loan is written off, resulting in a reduction of amortized cost basis and a corresponding adjustments to the allowance for credit losses. In some cases, the Company will modify a certain loan by providing multiple types of concessions. 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 or reduction of rate, may be granted. Of the loans modified as of September 30, 2024 , $ 17.7 million were on non-accrual status and partial charge-offs have in some cases been taken against the outstanding balance. The allowance for credit losses incorporates an estimate of lifetime expected credit losses and is recorded on each loan upon loan origination or acquisition. The starting point for the estimate of the allowance for credit losses is historical loss information, which includes losses from modifications of loans to borrowers experiencing financial difficulty. The Company uses probability of default/loss given default, discounted cash flows or remaining life method to determine the allowance for credit losses. An assessment of whether a borrower is experiencing financial difficulty is made on the date of a modification. Because the effect of most modifications made to borrowers experiencing financial difficulty is already included in the allowance for credit losses because of the measurement methodologies used to estimate the allowance, a change to the allowance for credit losses is generally not recorded upon modification. The following table shows the amortized cost basis at the end of the reporting period of the loans modified to borrowers experiencing financial difficulty, disaggregated by loan category and type of modification granted during the three and nine months ended September 30, 2024 . The percentage of the amortized cost basis of loans that were modified to borrowers experiencing financial difficulty as compared to the amortized cost basis of each class of loan category is also presented below: Loans Modifications Made to Borrowers Experiencing Financial Difficulty Three Months Ended September 30, 2024 Loans Modifications Made to Borrowers Experiencing Financial Difficulty Nine Months Ended September 30, 2024 (Dollars in Thousands) (Dollars in Thousands) Term Extension Term Extension Loan Type Amortized Cost Basis Percent of total loans by Amortized Cost Basis Percent of total loans by Real Estate: Residential $ — — $ 41 0.00 % Commercial 299 0.01 % 642 0.02 % Construction — — — — Other Loans: Commercial 202 0.02 % 18,492 1.78 % Home equity and improvement — — — — Consumer finance — — — — Total $ 501 $ 19,175 The following table describes the financial effect of the modifications made to borrowers experiencing financial difficulty: Term Extension Loan Type Financial Effect Real Estate: Residential -Term extended 6 months Commercial -Term extended 6 months Other Loans: Commercial -Demand Line termed out to 10 year term 5 year term 5 months -Demand Line termed out to 192 months 189 months -Term extended 6 months -Term extended 11 months -Term extended 5 years Rate Reduction Loan Type Financial Effect Real Estate: Other Loans: Commercial -Interest rate reduction 10.5 % to 8.5 % 11 % (tied to prime) to 8.25 % fixed 13.5 % to 8.5 % 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. There were no modification loans that had a payment default during the quarter ended September 30, 2024 and were modified in the twelve months prior to that default to borrowers experiencing financial difficulty. The Company closely monitors the performance of the loans that were modified to borrowers experiencing financial difficulty to understand the effectiveness of its modification efforts. Nine of the modified loans are current and seven modified loans pertaining to three commercial loan relationships are on nonaccrual status as of September 30, 2024. Credit Quality Indicators Loans are categorized into risk categories based on relevant information about the ability of borrowers to service their debt such as: current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. Loans are analyzed individually by classifying the loans by credit risk. This analysis includes all non-homogeneous loans, such as commercial and commercial real estate loans and certain homogeneous mortgages, home equity and consumer loans. This analysis is performed on a quarterly basis. Premier uses the following definitions for risk ratings: Special Mention. Loans classified as special mention have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the institution's credit position at some future date. Substandard. Loans classified as substandard are inadequately protected by the current net worth and paying 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 the institution 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, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. Loans not meeting the criteria above that are analyzed individually as part of the above described process are considered to be pass rated loans.

the allowance for credit loss ("ACL"), which requires a projection of credit loss over the contract lifetime of the credit adjusted for prepayment tendencies. This valuation account is deducted from the loans amortized cost basis to present the net amount expected to be collected on the loan. The ACL is adjusted through the provision for credit losses and reduced by net charge offs of loans. The credit loss estimation process involves procedures that consider the unique characteristics of the Company’s portfolio segments. These segments are further disaggregated into the loan pools for monitoring. When computing allowance levels, a model of risk characteristics, such as loss history and delinquency status, along with current conditions and a supportable forecast is used to determine credit loss assumptions. The Company is generally utilizing two methodologies to analyze loan pools, DCF and probability of default/loss given default (“PD/LGD”). A default can be triggered by one of several different asset quality factors including past due status, non-accrual status, modification status or if the loan has had a charge-off. The PD/LGD utilizes charge off data from the Federal Financial Institutions Examination Council to construct a default rate. This default rate is further segmented based on the risk of the credit assigning a higher default rate to riskier credits. The DCF methodology was selected as the most appropriate for loan segments with longer average lives and regular payment structures. The DCF model has two key components, the loss driver analysis combined with a cash flow analysis. The contractual cash flow is adjusted for PD/LGD and prepayment speed to establish a reserve level. The prepayment studies are updated quarterly by a third-party for each applicable pool. The Company estimates losses over an approximate one-year forecast period using Moody’s baseline economic forecasts, and then reverts to longer term historical loss experience over a three-year period. The remaining life method was selected for the consumer direct loan segment since the pool contains loans with many different structures and payment streams and collateral. The weighted average remaining life uses an average annual charge-off rate applied to the contractual term, further adjusted for estimated prepayments to determine the unadjusted historical charge-off rate for the remaining balance of assets.

The Company has made the accounting policy election not to measure an ACL for accrued interest receivables for all loan segments. Current policy dictates that a loan will be placed on nonaccrual status, with the current accrued interest receivable balance being written off, upon the loan being 90 days delinquent or when the loan is deemed to be collateral dependent and the collateral analysis shows less than 1.2 times discounted collateral coverage based on a current assessment of the value of the collateral. In addition, ASC Topic 326 requires the Company to establish a liability for anticipated credit losses for unfunded commitments. To accomplish this, the Company must first establish a loss expectation for extended (funded) commitments. This loss expectation, expressed as a ratio to the amortized cost basis, is then applied to the portion of unfunded commitments not considered unilaterally cancelable and is considered by the Company’s management as likely to fund over the life of the instrument. At September 30, 2024 , the Company had $ 1.3 billion in unfunded commitments and set aside $ 3.5 million in anticipated credit losses. This reserve is recorded in other liabilities as opposed to the ACL. The determination of ACL is complex and the Company makes decisions on the effects of matters that are inherently uncertain.

The Company also has a $ 50.0 million credit line at US Bank as of September 30, 2024 and December 31, 2023, respectively, which also was not drawn upon. In September 2020, the Company completed the issuance of $ 50.0 million aggregate principal amount, fixed-to-floating rate subordinated notes due September 30, 2030 in a private offering exempt from the registration requirements under the Securities Act of 1933, as amended. The notes carry a fixed rate of 4.0 % for five years at which time they will convert to a floating rate based on the secured overnight borrowing rate, plus a spread of 388.5 basis points. The Company may, at its option, beginning September 30, 2025, redeem the notes, in whole or in part, from time to time, subject to certain conditions. The net proceeds from the sale were approximately $ 48.7 million, after deducting the estimated offering expenses. The Company has used, and intends to continue using, the net proceeds for general corporate purposes, which may include, without limitation, providing capital to support its growth organically or through strategic acquisitions, repaying indebtedness, in financing investments, capital expenditures, repurchasing its common shares and for investments in the Bank as regulatory capital. The subordinated debentures are included in "Total Capital", as such term is defined under current regulatory guidelines and interpretations. In March 2007, the Company sponsored an affiliated trust, First Defiance Statutory Trust II (“Trust Affiliate II”) that issued $ 15.0 million of Guaranteed Capital Trust Securities (“Trust Preferred Securities”). In connection with this transaction, the Company issued $ 15.5 million of Junior Subordinated Deferrable Interest Debentures ("Subordinated Debentures") to Trust Affiliate II. The Company formed Trust Affiliate II for the purpose of issuing Trust Preferred Securities to third-party investors and investing the proceeds from the sale of these capital securities solely in Subordinated Debentures of the Company. The Subordinated Debentures held by Trust Affiliate II are the sole assets of that trust. The Company is not considered the primary beneficiary of Trust Affiliate II (variable interest entity), therefore, the trust is not consolidated in the Company’s financial statements, but rather the Subordinated Debentures are shown as a liability. Distributions on the Trust Preferred Securities issued by Trust Affiliate II are payable quarterly at a variable rate equal to the three-month SOFR rate plus 1.5 % .

The Trust Preferred Securities and Subordinated Debentures mature on September 15, 2037, but can be redeemed at the Company’s option at any time.

In connection with this transaction, the Company issued $ 20.6 million of Subordinated Debentures to Trust Affiliate I. Trust Affiliate I was formed for the purpose of issuing Trust Preferred Securities to third-party investors and investing the proceeds from the sale of these capital securities solely in Subordinated Debentures of the Company. The Junior Debentures held by Trust Affiliate I are the sole assets of the trust. The Company is not considered the primary beneficiary of Trust Affiliate I (variable interest entity), therefore the trust is not consolidated in the Company’s financial statements, but rather the subordinated debentures are shown as a liability. Distributions on the Trust Preferred Securities issued by Trust Affiliate I are payable quarterly at a variable rate equal to the three-month SOFR rate plus 1.38 % . The coupon rate payable on the Trust Preferred Securities issued by Trust Affiliate I was 6.59 % and 7.03 % on September 30, 2024 and December 31, 2023, respectively. The Trust Preferred Securities issued by Trust Affiliate I are subject to mandatory redemption, in whole or in part, upon repayment of the Subordinated Debentures. The Company has entered into an agreement that fully and unconditionally guarantees the Trust Preferred Securities subject to the terms of the guarantee. The Trust Preferred Securities and Subordinated Debentures mature on December 15, 2035, but can be redeemed at the Company’s option at any time now. The Subordinated Debentures related to the Trust Preferred Securities may be included in Tier 1 capital (with certain limitations applicable) under current regulatory guidelines and interpretations. Interest on both issues of Trust Preferred Securities may be deferred for a period of up to five years at the option of the issuer.

Accounting Policies [Abstract]
Accounting Standards Update ("ASU")	Accounting Standards Update ("ASU") ASU No. 2023-06, Disclosure Improvements – Codification Amendments in Response to the Securities and Exchange Commission’s ("SEC") Disclosure Update and Simplification Initiative: On October 9, 2023, the Financial Accounting Standards Board (the "FASB") issued ASU 2023-06 “Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative,” which incorporates 14 of the 27 disclosures referred by the SEC in Release No. 33-10532, “Disclosure Update and Simplification,” that was issued August 17, 2018. The changes modify the disclosure or presentation requirements of a variety of topics including statement of cash flows, accounting changes and error corrections, earnings per share, interim reporting, commitments, debt, equity, derivatives and hedging, and secured borrowing and collateral. For entities subject to the SEC’s existing disclosure requirements and for entities required to file or furnish financial statements with or to the SEC in preparation for the sale of or for purposes of issuing securities that are not subject to contractual restrictions on transfer, the effective date for each amendment is the date on which the SEC removes that related disclosure from its rules. For all other entities, the amendments will be effective two years later. If the SEC has not removed the related disclosure from its regulations by June 30, 2027, the amendments will be removed from the codification and not become effective for any entity. This ASU is not expected to have a material effect on the Company’s consolidated condensed financial statements. ASU No. 2023-07, Segment Reporting (Topic 280) – Improvements to Reportable Segment Disclosures: On November 27, 2023, the FASB issued ASU 2023-07 “Segment Reporting (Topic 820): Improvements to Reportable Segment Disclosure,” which requires public entities to disclose significant expense categories and amounts for each reportable segment, an amount for and description of the composition of “other segment items,” the title and position of the entity’s Chief Operating Decision Maker (the "CODM") and explanation of how the CODM uses the reported measures of profit or loss to assess segment performance, and – on an interim basis – certain segment-related disclosures that previously were required only on an annual basis. This ASU clarifies that entities with a single reportable segment are subject to both new and existing segment reporting requirements and that an entity is permitted to disclose multiple measures of segment profit or loss, provided that certain criteria are met. The amendments are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. Entities must adopt the changes to the segment reporting guidance on a retrospective basis. This ASU is not expected to have a material effect on the Company’s consolidated condensed financial statements. ASU No. 2023-09, Income Taxes (Topic 740) – Improvements to Income Tax Disclosures: On December 14, 2023, the FASB issued ASU 2023-09 “Income Taxes (Topic 740): Improvements to Income Tax Disclosures,” to address requests for improved income tax disclosures from investors, lenders, creditors and other allocators of capital that use the financial statements to make capital allocation decisions. This ASU is intended to improve the transparency of tax disclosures by requiring (1) consistent categories and greater disaggregation of information in the rate reconciliation and (2) income taxes paid disaggregated by jurisdiction, in addition to certain other amendments intended to improve the effectiveness of income tax disclosures. For public business entities, this ASU is effective for annual periods beginning after December 15, 2024. For other entities, this ASU is effective for annual periods beginning after December 15, 2025. Early adoption is permitted for annual financial statements that have not yet been issued or made available for issuance. This ASU is not expected to have a material effect on the Company’s consolidated condensed financial statements. SEC Final Rules Not Yet Adopted The Enhancement and Standardization of Climate-Related Disclosures for Investors: On March 6, 2024, the SEC approved the final rule for these disclosures, requiring registrants to provide information about climate-related risks that materially impact or are reasonably likely to materially impact a registrant's strategy, results of operations, or financial condition. The rule applies to all SEC reporting companies and may significantly increase reporting costs and complexities, including increased data collection and development of significant internal processes and controls. The final rule includes a phased-in compliance period, effective for the Company for the fiscal year ending December 31, 2025. On March 15, 2024, the U.S. Court of Appeals granted an administrative stay of the climate-related disclosure rules recently adopted by the SEC.
