CNB Financial Q3 2026 earnings rise to $27M

Nine-month diluted earnings per share reached $2.69, described by the company as a record for comparable periods.

Rhea-AI Filing Summary

CNB Financial Corporation (CCNE) reported Q3 2026 net income available to common shareholders of $27.0 million, versus $18.9 million a year earlier; diluted earnings per share was $0.91 versus $0.69. For the first nine months, net income available to common shareholders was $80.2 million versus $42.2 million, with diluted earnings per share of $2.69 versus $1.81.

Third-quarter revenue was $87.8 million versus $77.7 million, and net interest margin was 3.89% versus 3.69%. Organic loans totaled $6.5 billion as of September 30, 2026, excluding $124.1 million of syndicated loans. Deposits were $7.0 billion and declined $32.6 million from the prior quarter after the exit of approximately $76.1 million of higher-cost corporate deposits; excluding that exit, deposits increased approximately $43.5 million.

Nonperforming assets were $56.9 million as of September 30, 2026, versus $40.4 million a year earlier; quarterly net loan charge-offs were $2.4 million versus $957,000. Pre-tax unrealized securities losses were $81.9 million, or 8.98% of shareholders’ equity, while capital ratios would still exceed regulatory well-capitalized levels if those losses were fully recognized. The company recast certain 2025 comparisons after adopting ASU 2025-08, which affected credit-loss expense timing but not acquired assets’ economics or cash flows; it said the change was not an error, correction, or restatement.

How this balance works

Rhea-AI gives every point it takes from this document a weight. Minor counts 1, Moderate 3 and Major 9, so one Major point outweighs several Minor ones. The bar adds up the weights on each side, and when neither side holds more than 65% of the total the balance reads Mixed.

It reads the document as published, with the same rules for every company, and it does not look at what the market expected or at how the stock traded, so a point can be objectively good on a day the stock falls.

Rhea-AI Sentiment measures something else, the tone of the wording.

Filing Explained

After a 1.6 million dollar charge-off, one commercial and industrial relationship had 3.0 million dollars outstanding and an approximately 2.0 million dollar reserve.

As of September 30, 2026, CNB Financial classified $78.0 million of deposits as held for sale in connection with a planned sale of certain customer accounts; the disclosed disposition is planned, not completed.

The release says the decrease in nonperforming assets from the prior quarter was primarily tied to a $1.6 million charge-off on one commercial and industrial relationship. After the charge-off, the relationship had $3.0 million outstanding and an approximately $2.0 million reserve.

5 terms

net interest margin financial

"Net interest margin was 3.89%"

Net interest margin measures how much a bank earns from lending and investing compared with what it pays for funding, expressed as a percentage of its interest-earning assets. Think of it like a grocery store’s markup: it shows the gap between buying cost and selling price per dollar of goods — here, the cost is interest paid and the sale is interest received. Investors watch it because a higher margin usually means a bank is more profitable and better at managing interest rate and credit conditions.

Organic Loans financial

"Total loans excluding $124.1 million of syndicated loan balances"

nonperforming assets financial

"Total nonperforming assets were approximately $56.9 million"

Nonperforming assets are loans or investments that are not generating expected payments or returns because the borrower has fallen behind on payments or the investment has lost value. They matter to investors because a high level of nonperforming assets can indicate financial trouble for a bank or institution, potentially affecting its stability and profitability.

pre-provision net revenue financial

"Pre-provision net revenue ("PPNR"), a non-GAAP measure"

Pre-provision net revenue is a bank’s income from core operations — interest earned minus interest paid plus fees and other operating income, after operating costs — measured before setting aside funds for potential loan losses. Investors use it to gauge how well a bank’s everyday business generates money independent of one-time loss reserves, like judging a store’s sales and operating profit before accounting for an expected number of returned items.

FOR IMMEDIATE RELEASE

CNB FINANCIAL CORPORATION REPORTS THIRD QUARTER 2026 RESULTS

Clearfield, Pennsylvania – October 21, 2026

CNB Financial Corporation (“Corporation”) (NASDAQ: CCNE), the parent company of CNB Bank, today announced its earnings for the three and nine months ended September 30, 2026.

Certain comparative financial information for the prior year's three and nine month periods ended September 30, 2025 has been recast to reflect the Corporation's adoption of Accounting Standards Update 2025-08, Financial Services - Credit Losses (Topic 326): Purchased Financial Assets. The recast primarily eliminates the recognition of Day 1 provision expense associated with acquired loans and records an allowance for credit losses as of the acquisition date. The adoption had no impact on the economics or cash flows of the acquired assets but affected the timing of credit loss expense recognition. This change is not the result of an error, correction, or restatement of previously issued financial statements, but rather, it enhances comparability among periods presented in accordance with applicable financial reporting guidance. Accordingly, certain comparative amounts presented herein differ from those previously reported for these prior year periods.

Key Financial Trends

•Earnings - Net income available to common shareholders ("earnings") was $27.0 million, or $0.91 per diluted share, for the three months ended September 30, 2026, compared to $27.2 million, or $0.91 per diluted share, for the three months ended June 30, 2026, and $18.9 million, or $0.69 per diluted share, for the three months ended September 30, 2025. Earnings for the three months ended September 30, 2026, decreased $244 thousand compared to earnings for the three months ended June 30, 2026, while diluted earnings per share remained unchanged at $0.91.

◦Adjusted earnings for the three months ended September 30, 2025, a non-GAAP measure, were $22.5 million, or $0.82 per diluted share, with adjusted earnings excluding after-tax merger and integration costs ("merger transaction related expenses") related to the Corporation’s acquisition of ESSA Bancorp, Inc. (“ESSA”).1 Earnings for the three months ended September 30, 2026 increased $4.5 million, or $0.09 per diluted share, compared to adjusted earnings for the three months ended September 30, 2025.

•Loans - Total loans excluding $124.1 million of syndicated loan balances, or ("Organic Loans"), were $6.5 billion as of September 30, 2026. During the three months ended September 30, 2026, Organic Loans increased by $76.5 million, or 1.19% (4.73% annualized), from June 30, 2026.1 The increase in Organic Loans was primarily driven by growth in commercial real estate and residential real estate loans.

•Deposits - At September 30, 2026, total deposits were $7.0 billion. During the three months ended September 30, 2026, deposits declined by $32.6 million, or 0.46% (1.83% annualized), compared to June 30, 2026. The third quarter of 2026 included the impact of the Bank's strategy to exit certain higher cost corporate deposits totaling approximately $76.1 million, with an average interest cost of 3.69%. Excluding the impact of this strategic corporate deposits exit, total deposits increased approximately $43.5 million, or 0.61% (2.44% annualized), compared to the second quarter of 2026. Noninterest-bearing deposits increased for the quarter by $13.5 million, or 1.18% (4.67% annualized), compared to June 30, 2026, primarily driven by additional and expanded treasury management customer relationships.

•Net Interest Margin - Net interest margin was 3.89% for the three months ended September 30, 2026, compared to 3.88% for the three months ended June 30, 2026. Net interest margin on a fully tax-equivalent basis, a non-GAAP measure, was 3.89% and 3.89%, for the three months ended September 30, 2026 and June 30, 2026, respectively.1 Included in net interest margin on a fully tax-equivalent basis was $2.7 million and $4.8 million of purchase accounting loan accretion for the three months ended September 30, 2026 and June 30, 2026, respectively.

•Credit Quality - Total nonperforming assets were approximately $56.9 million, or 0.68% of total assets, as of September 30, 2026, compared to $58.4 million, or 0.69% of total assets, as of June 30, 2026. The decrease in nonperforming assets was primarily the result of charge-offs of approximately $1.6 million on one commercial and industrial relationship, as discussed in more detail below.

◦Net loan charge-offs for the three months ended September 30, 2026 were $2.4 million, or 0.14% (annualized) of average total loans and loans held for sale, compared to net loan charge-offs of $1.4 million, or 0.09% (annualized) of average total loans and loans held for sale, during the three months ended June 30, 2026. The increase in net loan charge-offs was primarily the result of charge-offs of approximately $1.6 million on one commercial and industrial relationship, as discussed in more detail below.

•Capital - Book value per common share was $28.86 and $28.75 at September 30, 2026 and June 30, 2026, respectively. Book value per common share at September 30, 2026 reflects an increase of $0.11, or 0.38%, compared to book value per common share at June 30, 2026. The increase in book value per common share was primarily due to an increase in retained earnings (net of the payment of common and preferred stock dividends), partially offset by a higher accumulated other comprehensive loss, primarily reflecting the after-tax impact of temporary unrealized valuation changes in the Corporation's available-for-sale investment portfolio due to changes in market yields relative to securities maturity dates, and not from other than temporary impairments.

◦Tangible book value per common share, a non-GAAP measure, was $24.87 and $24.73 as of September 30, 2026 and June 30, 2026, respectively.1 Tangible book value per common share at September 30, 2026 reflects an increase of $0.14, or 0.57%, compared to the tangible book value per common share as of June 30, 2026.1 The increase in tangible book value per common share was partially offset by a higher accumulated other comprehensive loss, primarily reflecting the after-tax impact of temporary unrealized valuation changes in the Corporation's available-for-sale investment portfolio.

1 This release contains references to certain financial measures that are not defined by U.S. Generally Accepted Accounting Principles ("GAAP"). Management believes that these non-GAAP measures provide a greater understanding of ongoing operations, enhance the comparability of results of operations with prior periods, and reflect the effects of significant gains and charges in the periods presented. A reconciliation of these non-GAAP financial measures is provided in the "Reconciliation of Non-GAAP Financial Measures" section.

Executive Summary

•Earnings were $27.0 million, or $0.91 per diluted share, for the three months ended September 30, 2026, compared to $27.2 million, or $0.91 per diluted share, for the three months ended June 30, 2026, and $18.9 million, or $0.69 per diluted share, for the three months ended September 30, 2025. Earnings for the three months ended September 30, 2026, decreased $244 thousand compared to earnings for the three months ended June 30, 2026, while diluted earnings per share remained unchanged at $0.91.

◦Adjusted earnings for the three months ended September 30, 2025, a non-GAAP measure, were $22.5 million, or $0.82 per diluted share, with adjusted earnings excluding merger transaction related expenses related to the Corporation’s acquisition of ESSA.1 Earnings for the three months ended September 30, 2026 increased $4.5 million, or $0.09 per diluted share, compared to adjusted earnings for the three months ended September 30, 2025, due to organic growth coupled with the overall impact of the acquisition of ESSA.1

•Earnings were $80.2 million, or $2.69 per diluted share, for the nine months ended September 30, 2026, compared to $42.2 million, or $1.81 per diluted share, for the nine months ended September 30, 2025.

◦Adjusted earnings for the nine months ended September 30, 2025, a non-GAAP measure, were $47.6 million, or $2.05 per diluted share, with adjusted earnings excluding merger transaction related expenses related to the Corporation’s acquisition of ESSA.1 Earnings for the nine months ended September 30, 2026 increased $32.6 million, or $0.64 per diluted share, compared to adjusted earnings for the nine months ended September 30, 2025, due primarily to the overall impact of the acquisition of ESSA.1

•At September 30, 2026, loans totaled $6.5 billion, excluding $124.1 million of syndicated loans. Organic Loans increased $76.5 million, or 1.19% (4.73% annualized), compared to June 30, 2026. Organic Loan growth was $83.8 million, or 1.31%, compared to September 30, 2025. The increase in loans for the quarter ended September 30, 2026, compared to the quarter ended June 30, 2026, was primarily driven by increases in commercial real estate and residential real estate loans. The year-over-year growth in loans as of September 30, 2026, compared to September 30, 2025, was primarily driven by growth in the Ridge View Bank and ERIEBANK markets. The year-over-year growth was also significantly impacted by an increased level of commercial real estate ("CRE") loan prepayments, including full repayments of $71.4 million of CRE loans acquired in 2025 as a result of the ESSA acquisition, and a full payoff of $40.0 million of the Corporation’s largest office building loan related to a CRE property in the BankOnBuffalo division.

◦At September 30, 2026, the syndicated loan portfolio totaled $124.1 million, or 1.87% of total loans, compared to $93.9 million, or 1.44% of total loans, at June 30, 2026 and $71.9 million, or 1.11% of total loans, at September 30, 2025. The increase in syndicated lending balances of $30.2 million compared to June 30, 2026, which includes both new credits as well as additional credit extensions on existing quality borrowers, reflects the Corporation's continued focus on evaluating the level and composition of its syndicated loan portfolio to ensure it continues to provide strong credit quality and profitable use of excess liquidity, while complementing the Corporation’s loan growth from its in-market customer relationships. The Corporation’s portfolio of syndicated credits includes only commercial and industrial loans and no CRE exposure.

•At September 30, 2026, total deposits were $7.0 billion. Deposits declined for the quarter by $32.6 million, or 0.46% (1.83% annualized), compared to June 30, 2026. The third quarter of 2026 included the strategic exit of higher cost corporate deposits totaling approximately $76.1 million, with an average interest cost of 3.69%. Excluding the impact of the corporate deposits exit, total deposits increased approximately $43.5 million, or 0.61% (2.44% annualized), compared to the second quarter of 2026. Total deposits increased $147.6 million, or 2.14%, compared to September 30, 2025. The year-over-year growth in deposits as of September 30, 2026, compared to September 30, 2025, was primarily driven by both additional and expanded treasury management customer relationships. Noninterest-bearing deposits increased for the quarter by $13.5 million, or 1.18% (4.67% annualized), compared to June 30, 2026, were also the result of additional and expanded treasury management customer relationships. The $78.0 million in deposits classified as held for sale as of September 30, 2026 are associated with a planned sale of certain customer deposit accounts that are part of a broader strategic initiative to optimize the Corporation’s branch and market footprint following the ESSA acquisition. Additional deposit and liquidity profile details were as follows:

◦At September 30, 2026, the total estimated uninsured deposits for CNB Bank were approximately $2.1 billion, or 30.02% of total CNB Bank deposits. When excluding $22.3 million of affiliate company deposits and $760.4 million of pledged-investment collateralized deposits, adjusted total estimated uninsured deposits as of September 30, 2026 were approximately $1.4 billion, or 19.07% of total CNB Bank deposits.

▪Total estimated uninsured deposits for CNB Bank at June 30, 2026 were approximately $2.1 billion, or approximately 28.83% of total CNB Bank deposits. Excluding $21.2 million of affiliate company deposits and $704.2 million of pledged-investment collateralized deposits, adjusted total estimated uninsured deposits as of June 30, 2026 were approximately $1.3 billion, or approximately 18.73% of total CNB Bank deposits.

◦At September 30, 2026, the Corporation had $221.2 million of cash equivalents held at CNB Bank’s interest-bearing deposit account at the Federal Reserve. These excess funds, when combined with total contingent liquidity resources of $6.2 billion including (i) available borrowing capacity from both the Federal Home Loan Bank of Pittsburgh ("FHLB") and the Federal Reserve, and (ii) available unused commitments from brokered deposit sources and other third-party funding channels, including previously established lines of credit from correspondent banks, resulted in the total available liquidity sources for the Corporation as of September 30, 2026 of approximately 4.7 times the estimated amount of adjusted uninsured deposit balances discussed above.

•At September 30, 2026 and June 30, 2026, the Corporation had $164.0 million outstanding in short-term borrowings. The Corporation had $181.6 million outstanding short-term borrowings at September 30, 2025. The decrease in short-term borrowings at September 30, 2026 compared to September 30, 2025 was attributable to the repayment of certain borrowings assumed with the ESSA acquisition.

•At September 30, 2026, the Corporation's pre-tax net unrealized losses on the combined portfolios of available-for-sale and held-to-maturity securities totaled $81.9 million, or 8.98% of total shareholders' equity, compared to $54.8 million, or 6.02% of total shareholders' equity, at June 30, 2026, and $49.8 million, or 5.81% of total shareholders' equity, at September 30, 2025. The change in unrealized losses during the third quarter of 2026 compared to the second quarter of 2026, as well as for the quarter ended September 30, 2025, was primarily due to changes in the yield curve, coupled with the Corporation’s scheduled bond maturities, which were all realized at par. Importantly, all regulatory capital ratios for the Corporation would still exceed regulatory “well-capitalized” levels as of September 30, 2026, June 30, 2026, and September 30, 2025 if the net unrealized losses at the respective dates were fully recognized.

•Total nonperforming assets were $56.9 million, or 0.68% of total assets, as of September 30, 2026, compared to $58.4 million, or 0.69% of total assets, as of June 30, 2026, and were $40.4 million, or 0.49% of total assets, as of September 30, 2025. The decrease of $1.6 million at September 30, 2026 compared to June 30, 2026 was primarily driven by charge-offs related to one commercial and industrial relationship during the third quarter of 2026. After the $1.6 million charge-off at September 30, 2026, the relationship had an outstanding balance of $3.0 million and a related reserve of approximately $2.0 million. The $16.5 million increase in nonperforming assets at September 30, 2026, compared to September 30, 2025, was primarily driven by two previously disclosed relationships: a commercial and industrial relationship totaling $7.2 million and a commercial relationship totaling $6.8 million. Net loan charge-offs for the three months ended September 30, 2026 were $2.4 million, or 0.14% (annualized) of average total loans and loans held for sale, compared to net loan charge-offs of $1.4 million, or 0.09% (annualized) of average total loans and loans held for sale, during the three months ended June 30, 2026, and $957 thousand, or 0.06% (annualized) of average total loans and loans held for sale, during the three months ended September 30, 2025.

•Pre-provision net revenue ("PPNR"), a non-GAAP measure, was $36.7 million for the three months ended September 30, 2026 and $36.9 million and $27.5 million for the three months ended June 30, 2026 and September 30, 2025, respectively.1 Excluding merger and integration costs, adjusted PPNR was $31.7 million for the three months ended September 30, 2025.1 The quarter-over-quarter change in PPNR was driven by higher non-interest expense, partially offset by an increase in non-interest income. For the three months ended September 30, 2026, the increase in PPNR compared to the three months ended September 30, 2025 was primarily attributable to stronger net interest income and non-interest income, partially offset by higher non-interest expenses. PPNR was $107.8 million for the nine months ended September 30, 2026, compared to $65.0 million for the nine months ended September 30, 2025.1 Excluding merger and integration costs, adjusted PPNR was $71.1 million for the nine months ended September 30, 2025.1 The year-to-date 2026 PPNR when compared to the same year-to-date period in 2025 PPNR, excluding merger and integration costs, reflected increases in net interest income and non-interest income, partially offset by an increase in non-interest expense.

"Earnings of $2.69 per diluted share for the first nine months of 2026 were a record for the Corporation versus comparable periods in any prior years, as we sustained positive operating performance in the third quarter consistent with the first half of 2026”, stated Michael Peduzzi, President and CEO of both the Corporation and CNB Bank. “The expanded revenue base and operating efficiencies realized as a result of the ESSA acquisition in July 2025 have added to the continuing solid performance in our legacy banking divisions across our four-state footprint. We continue to realize qualitative growth from both new and expanded relationships in lending and treasury management activities, and see a sound loan production pipeline and both retail and treasury management deposit growth opportunities entering the fourth quarter. Despite the headwinds of an increased yield curve contributing to increased temporary after-tax unrealized losses on our available-for-sale investment portfolio, we continue to have sustained post-dividend retained earnings to favorably accrete tangible book value as we strive to achieve an acceleration of the post-acquisition earn-back period when compared to our pre-merger model projections. We remain well-positioned from an interest rate risk management position to sustain a positive net interest margin in the current changing interest rate environment. Complementing our core operating activities, we also implemented a tax management strategy to purchase renewable energy tax credits at a discount, and apply them to reduce our income tax expense. Importantly, all of these activities are conducted upon an operating foundation reflecting our ongoing commitment to disciplined underwriting, enterprise risk management and sound controls, and effective but well-secured use of expanded technological capabilities. We are pleased with our current financial position and our sustained earnings momentum."

Other Balance Sheet Highlights

•Book value per common share was $28.86, $28.75, and $27.12 at September 30, 2026, June 30, 2026, and September 30, 2025, respectively. Excluding the after-tax impact of merger transaction related expenses, book value per common share was $27.30 at September 30, 2025.1 Book value per common share at September 30, 2026 reflects an increase of $0.11, or 0.38%, compared to book value per common share at June 30, 2026. The increase in book value per common share from June 30, 2026 to September 30, 2026 was primarily due to an increase in retained earnings (net of the payment of common and preferred stock dividends), partially offset by an increase in accumulated other comprehensive loss primarily from the after-tax impact of temporary unrealized valuation changes in the Corporation’s available-for-sale investment portfolio. The increase in book value per common share of $1.56, or 5.71%, from September 30, 2025 to September 30, 2026, when excluding the after-tax impact of merger transaction related expenses, was primarily driven by growth in retained earnings, net of common and preferred stock dividends, partially offset by a higher accumulated other comprehensive loss, primarily reflecting the after-tax impact of temporary unrealized valuation changes in the Corporation's available-for-sale investment portfolio.1

•Tangible book value per common share, a non-GAAP measure, was $24.87, $24.73, and $22.76 as of September 30, 2026, June 30, 2026, and September 30, 2025, respectively.1 Excluding the after-tax impact of merger transaction related expenses, tangible book value per common share was $22.94 as of September 30, 2025.1 Tangible book value per common share for September 30, 2026 reflects an increase of $0.14, or 0.57%, compared to tangible book value per common share as of June 30, 2026. Adjusted tangible book value per common share (non-GAAP) increased $1.93, or 8.41%, from September 30, 2025 to September 30, 2026, primarily due to growth in retained earnings, net of common and preferred stock dividends, partially offset by a higher accumulated other comprehensive loss, primarily reflecting the after-tax impact of temporary unrealized valuation changes in the Corporation's available-for-sale investment portfolio.1

Loan Portfolio Profile

•As part of its lending policy and credit risk management activities, the Corporation tracks lending exposure by industry classification and type to determine potential risks associated with industry concentrations, and to identify any concentration risk issues that could lead to additional credit loss exposure. An important and recurring part of this process involves the Corporation’s continued measurement and evaluation of its exposure to the office, hospitality, and multifamily industries within its commercial real estate portfolio. Even with the Corporation’s historically sound underwriting protocols and high credit quality standards for borrowers in the commercial real estate industry segments, the Corporation monitors numerous relevant sensitivity elements, including occupancy, loan-to-value, absorption and cap rates, debt service coverage and covenant compliance, and developer/lessor financial strength both in the project and globally. At September 30, 2026, the Corporation had the following key metrics related to its office, hospitality, and multifamily portfolios with such metrics including the impact on the respective portfolios of loans acquired during the third quarter of 2025 from the ESSA acquisition, as well as notable early payoffs of larger CRE credits occurring in the first quarter of 2026 as previously noted:

◦Commercial office loans:

▪There were 140 outstanding loans, totaling $132.0 million, or 1.99% of total loans outstanding;

▪There were two nonaccrual commercial office loans that totaled $2.0 million, or 1.55% of total commercial office loans outstanding;

▪There was one past-due commercial office loan that totaled $202 thousand, or 0.15% of the total commercial office loans outstanding; and

▪The average outstanding balance per commercial office loan was $943 thousand.

◦Commercial hospitality loans:

▪There were 148 outstanding loans, totaling $370.2 million, or 5.59% of total loans outstanding;

▪There were no nonaccrual commercial hospitality loans;

▪There were no past-due commercial hospitality loans; and

▪The average outstanding balance per commercial hospitality loan was $2.5 million.

◦Commercial multifamily loans:

▪There were 331 outstanding loans, totaling $539.7 million, or 8.15% of total loans outstanding;

▪There were two nonaccrual commercial multifamily loans that totaled $721 thousand, or 0.13% of total multifamily loans outstanding;

▪There were four past-due commercial multifamily loans that totaled $2.9 million, or 0.54% of total multifamily loans outstanding; and

▪The average outstanding balance per commercial multifamily loan was $1.6 million.

The Corporation had no commercial office, hospitality or multifamily loan relationships considered by the banking regulators to be high volatility commercial real estate ("HVCRE") credits. No credits acquired from ESSA were considered HVCRE.

Performance Ratios

•Annualized return on average equity was 12.09%, 12.65%, and 10.05% for the three months ended September 30, 2026, June 30, 2026 and September 30, 2025, respectively. Excluding the impact of merger transaction related expenses, annualized return on average equity was 11.86% for the three months ended September 30, 2025.1 Annualized return on average equity was 12.38% for the nine months ended September 30, 2026.

•Annualized return on average tangible common equity, a non-GAAP measure, was 14.39%, 15.20% and 12.03% for the three months ended September 30, 2026, June 30, 2026, and September 30, 2025, respectively.1 Excluding the impact of merger transaction related expenses, annualized return on average tangible common equity was 14.33% for the three months ended September 30, 2025.1 Annualized return on average tangible common equity was 14.84% for the nine months ended September 30, 2026. Annualized return on average tangible common equity was 10.13% for the nine months ended September 30, 2025. Excluding the impact of merger transaction related expenses, annualized return on average tangible common equity was 11.42% for the nine months ended September 30, 2025.1

•The Corporation's efficiency ratio was 58.21%, 57.86% and 64.56% for the three months ended September 30, 2026, June 30, 2026 and September 30, 2025, respectively, and 56.53%, 56.14% and 62.97%, respectively, on a fully tax-equivalent basis, a non-GAAP measure.1 Excluding merger and integration costs, the efficiency ratio on a fully tax-equivalent basis was 57.67% for the three months ended September 30, 2025.1 The linked-quarter increase, on a fully tax-equivalent basis, represented an increase of 39 basis points compared to June 30, 2026, primarily driven by higher non-interest expense, as further discussed below. The year-over-year decrease was primarily driven by an increase in net interest income, partially offset by an increase in non-interest expense. The Corporation's efficiency ratio was 58.35% for the nine months ended September 30, 2026, and 56.65% on a fully tax-equivalent basis, a non-GAAP measure.1 The Corporation's efficiency ratio was 66.80% for the nine months ended September 30, 2025, and 65.74% on a fully tax-equivalent basis, a non-GAAP measure.1 Excluding merger and integration costs, the efficiency ratio on a fully tax-equivalent basis was 62.68% for the nine months ended September 30, 2025. The year-over-year decrease was primarily driven by higher net interest income, partially offset by higher non-interest expense.

Revenue

•Total revenue (net interest income plus non-interest income) was $87.8 million for the three months ended September 30, 2026, compared to $87.6 million and $77.7 million for the three months ended June 30, 2026 and September 30, 2025, respectively.

◦Net interest income was $76.3 million for the three months ended September 30, 2026, compared to $76.3 million and $67.1 million for the three months ended June 30, 2026 and September 30, 2025, respectively. Net interest income increased $9.2 million, or 13.67%, for the three months ended September 30, 2026, compared to the three months ended September 30, 2025, primarily reflecting the impact of the ESSA acquisition and growth in the Corporation's legacy loan portfolio.

◦Net interest margin was 3.89%, 3.88%, and 3.69% for the three months ended September 30, 2026, June 30, 2026, and September 30, 2025, respectively. Net interest margin on a fully tax-equivalent basis, a non-GAAP measure, was 3.89%, 3.89% and 3.69% for the three months ended September 30, 2026, June 30, 2026, and September 30, 2025, respectively.1 Excluding the $2.7 million, $4.8 million, and $3.4 million in purchase accounting loan accretion realized in the third quarter of 2026, second quarter of 2026, and third quarter of 2025, respectively, the net interest margin on a fully tax-equivalent basis for the three months ended September 30, 2026, June 30, 2026, and September 30, 2025, was 3.75%, 3.65%, and 3.50%, respectively.1

▪The yield on earning assets of 5.85% for the three months ended September 30, 2026 decreased 3 basis points compared to the three months ended June 30, 2026 and decreased 11 basis points compared to the three months ended September 30, 2025. The decrease in yield in the third quarter of 2026 compared to the quarter ended June 30, 2026 was primarily attributable to a decrease in purchase accounting loan accretion. The decrease in yield during the third quarter of 2026 compared to the third quarter of 2025 was primarily attributable to lower average loan yields resulting from the Federal Reserve interest rate decreases during 2025.

▪The cost of interest-bearing liabilities was 2.48% for the three months ended September 30, 2026, reflecting decreases of 2 basis points and 35 basis points from the three months ended June 30, 2026 and the three months ended September 30, 2025, respectively. The decrease in the cost of interest-bearing liabilities is primarily the result of the Corporation’s targeted interest-bearing deposit rate decreases.

•Total revenue was $258.8 million for the nine months ended September 30, 2026 compared to $195.8 million for the nine months ended September 30, 2025.

◦Net interest income was $226.0 million for the nine months ended September 30, 2026 compared to $167.8 million for the nine months ended September 30, 2025. When comparing the nine months ended September 30, 2026 to the nine months ended September 30, 2025, the increase in net interest income of $58.2 million, or 34.70% (46.40% annualized), was primarily due to the impact of the ESSA acquisition and growth in the Corporation's legacy loan portfolio.

◦Net interest margin was 3.87% and 3.57% for the nine months ended September 30, 2026 and September 30, 2025, respectively. Net interest margin on a fully tax-equivalent basis, a non-GAAP measure, was 3.87% and 3.56% for the nine months ended September 30, 2026 and September 30, 2025, respectively.1 Excluding the $10.6 million and $3.4 million in purchase accounting loan accretion realized for the nine months ended September 30, 2026 and 2025, respectively, the net interest margin on a fully tax-equivalent basis was 3.69% and 3.49%, respectively.1

▪The yield on earning assets of 5.86% for the nine months ended September 30, 2026 decreased 1 basis point from September 30, 2025. The decrease in yield compared to September 30, 2025 was attributable to Federal Reserve interest rate decreases since mid-September 2025 until the most recent Federal Reserve rate increase in September 2026, partially offset by growth in higher-yielding securities.

▪The cost of interest-bearing liabilities of 2.50% for the nine months ended September 30, 2026 favorably decreased by 38 basis points from September 30, 2025, primarily the result of the Corporation’s targeted interest-bearing deposit rate decreases in response to the Federal Reserve rate decreases, coupled with the benefit of ESSA’s lower overall interest cost of deposits.

•Total non‑interest income was $11.5 million for the three months ended September 30, 2026, compared to $11.3 million and $10.6 million for the three months ended June 30, 2026 and September 30, 2025, respectively. The quarter-over-quarter increase was primarily attributable to an increase in wealth and asset management fees and treasury management fees, partially offset by a decrease in net realized and unrealized gains on equity securities and gains from recoveries of acquired loans. The primary increase in wealth and asset management fees was due to a $1.1 million transition fee for the Corporation moving its existing retail investment business platform to a new provider. The year-over-year increase in non-interest income was primarily driven by increases in wealth and asset management fees, including the platform provider change transition fee, treasury management fees, and card processing and interchange income, partially offset by lower net realized and unrealized gains on equity securities and a decrease in net realized gains on available-for-sale securities.

•Total non-interest income was $32.8 million for the nine months ended September 30, 2026 compared to $28.1 million for the nine months ended September 30, 2025. This increase was primarily due to higher wealth and asset management fees (including the transition fee), treasury management fees, card processing and interchange income, mortgage banking income, and service charges on deposits, partially offset by lower pass-through income from small business investment companies ("SBICs").

Non-Interest Expense

•For the three months ended September 30, 2026, June 30, 2026, and September 30, 2025, total non‑interest expense was $51.1 million, $50.7 million, and $50.2 million, respectively. Excluding merger and integration costs, total non‑interest expense for the three months ended September 30, 2025 was $46.0 million.1 The quarter-over-quarter increase of $396 thousand, or 0.78%, was primarily driven by increases in salaries and benefits, partially offset by decreases in legal, professional, and examination fees and other non-interest expenses, including the timing of business development-related costs and other real estate owned expenses. The increase in salaries and benefits was driven primarily by an increase in incentive compensation accruals. The decrease in legal, professional, and examination fees was driven by the reversal of a legal accrual assumed as part of the ESSA acquisition. Excluding merger and integration costs, the $5.1 million, or 11.09%, increase in non-interest expense compared to the three months ended September 30, 2025 was primarily attributable to personnel, software licensing expenses, higher core system volume-based fees, and other operating costs associated with the ESSA acquisition.

•For the nine months ended September 30, 2026, total non-interest expense was $151.0 million compared to $130.8 million for the nine months ended September 30, 2025. Excluding merger and integration costs, total non‑interest expense for the nine months ended September 30, 2025 was $124.8 million.1 Excluding merger and integration costs, the increase of $26.2 million, or 21.02%, compared to the nine months ended September 30, 2025, was primarily attributable to higher personnel, occupancy and facilities costs, software licensing expenses, increased core system volume-based fees, and other operating costs associated with the ESSA acquisition.

Income Taxes

•Income tax expense for the three months ended September 30, 2026 was $5.2 million, representing a 15.53% effective tax rate, compared to $6.9 million, representing a 19.50% effective tax rate, for the three months ended June 30, 2026, and $5.5 million, representing a 21.51% effective tax rate, for the three months ended September 30, 2025. Income tax expense for the three months ended September 30, 2026 included the recognition of $1.2 million in renewable energy tax credits. Income tax expense for the nine months ended September 30, 2026 was $18.1 million, representing a 17.84% effective tax rate (including the benefit of the renewable energy tax credits), compared to $11.6 million, representing a 20.39% effective tax rate, for the nine months ended September 30, 2025.

Asset Quality

•Total nonperforming assets were $56.9 million, or 0.68% of total assets, as of September 30, 2026, compared to $58.4 million, or 0.69% of total assets, as of June 30, 2026, and $40.4 million, or 0.49% of total assets, as of September 30, 2025, as discussed in more detail above.

•The allowance for credit losses measured as a percentage of total loans was 1.04% as of September 30, 2026, June 30, 2026, and September 30, 2025, respectively. In addition, the allowance for credit losses as a percentage of nonaccrual loans was 127.89% as of September 30, 2026, compared to 123.00% and 187.94% as of June 30, 2026 and September 30, 2025, respectively.

•The provision for credit losses was $3.5 million for the three months ended September 30, 2026, compared to $1.8 million for the three months ended June 30, 2026, and $2.1 million for the three months ended September 30, 2025. The $1.7 million quarter-over-quarter increase in the provision for credit losses was primarily driven by a $1.6 million charge-off on one commercial loan relationship, as discussed in more detail above. The $1.4 million increase compared to the three months ended September 30, 2025, was primarily attributable to the $1.6 million charge-off on one commercial loan relationship, as discussed in more detail above. The provision for credit losses was $6.2 million for the nine months ended September 30, 2026, compared to $8.0 million for the nine months ended September 30, 2025. The $1.7 million decrease in the provision for credit losses compared to the nine months ended September 30, 2025, was primarily attributable to lower net loan charge-offs.

•As discussed in more detail above, for the three months ended September 30, 2026, net loan charge-offs were $2.4 million, or 0.14% (annualized) of average total loans and loans held for sale, compared to $1.4 million, or 0.09% (annualized) of average total loans and loans held for sale, during the three months ended June 30, 2026, and $957 thousand, or 0.06% (annualized) of average total loans and loans held for sale, during the three months ended September 30, 2025. Net loan charge-offs were $4.7 million, or 0.10% (annualized) for the nine months ended September 30, 2026, compared to $5.7 million, or 0.15% (annualized) for the nine months ended September 30, 2025.

Capital

•As of September 30, 2026, the Corporation’s total shareholders’ equity was $912.6 million, representing an increase of $3.1 million, or 0.34%, from June 30, 2026, and an increase of $55.4 million, or 6.47%, from September 30, 2025. The quarter-over-quarter increase was primarily driven by growth in retained earnings of $21.4 million, net of the payment of common and preferred stock dividends, partially offset by a $19.3 million increase in accumulated other comprehensive loss. The year-over-year increase was primarily driven by a $77.6 million increase in retained earnings, net of the payment of common and preferred stock dividends, partially offset by a $25.3 million increase in accumulated other comprehensive loss, during the twelve months ended September 30, 2026.

•Regulatory capital ratios for the Corporation continue to exceed regulatory “well-capitalized” levels as of September 30, 2026, consistent with prior periods.

•As of September 30, 2026, the Corporation’s ratio of common shareholders' equity to total assets was 10.19% compared to 10.10% at June 30, 2026 and 9.66% at September 30, 2025.

Consolidated Financial Data Notes:
(1) Management uses non-GAAP financial information in its analysis of the Corporation’s performance. Management believes that these non-GAAP measures provide a greater understanding of ongoing operations, enhance comparability of results of operations with prior periods and show the effects of significant gains and charges in the periods presented. The Corporation’s management believes that investors may use these non-GAAP measures to analyze the Corporation’s financial performance without the impact of unusual items or events that may obscure trends in the Corporation’s underlying performance. This non-GAAP data should be considered in addition to results prepared in accordance with GAAP, and is not a substitute for, or superior to, GAAP results. Limitations associated with non-GAAP financial measures include the risks that persons might disagree as to the appropriateness of items included in these measures and that different companies might calculate these measures differently. A reconciliation of these non-GAAP financial measures is provided below (dollars in thousands, except per share data).
(2) Capital ratios as of September 30, 2026 are estimated pending final regulatory filings.

Focusing on great experiences and mutually sustainable success for our clients, colleagues, and investors. Q3 2026 Earnings Supplement

2 CERTAIN IMPORTANT INFORMATION Certain comparative financial information for the three and nine months ended September 30, 2025 has been recast to reflect the Corporation's adoption of Accounting Standards Update 2025-08, Financial Services - Credit Losses (Topic 326): Purchased Financial Assets. The recast primarily eliminates the recognition of Day 1 provision expense associated with acquired loans and records an allowance for credit losses as of the acquisition date. The adoption had no impact on the economics or cash flows of the acquired assets but affected the timing of credit loss expense recognition. This change is not the result of an error, correction, or restatement of previously issued financial statements, but rather enhances comparability among periods presented in accordance with applicable financial reporting guidance. Accordingly, certain comparative amounts presented herein differ from those previously reported. CAUTION REGARDING FORWARD LOOKING STATEMENTS This presentation includes forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, with respect to the Corporation’s financial condition, liquidity, results of operations, future performance and business. These forward-looking statements are intended to be covered by the safe harbor for “forward-looking statements” provided by the Private Securities Litigation Reform Act of 1995. Forward-looking statements are those that are not historical facts. Forward-looking statements include statements with respect to beliefs, plans, objectives, goals, expectations, anticipations, estimates and intentions that are subject to significant risks and uncertainties and are subject to change based on various factors (some of which are beyond the Corporation’s control). Forward-looking statements often include the words “believes,” “expects,” “anticipates,” “estimates,” “forecasts,” “intends,” “plans,” “targets,” “potentially,” “probably,” “projects,” “outlook” or similar expressions or future conditional verbs such as “may,” “will,” “should,” “would” and “could.” The Corporation’s actual results may differ materially from those contemplated by the forward- looking statements, which are neither statements of historical fact nor guarantees or assurances of future performance. Such known and unknown risks, uncertainties and other factors that could cause the actual results to differ materially from the statements, include, but are not limited to, (i) adverse changes or conditions in capital and financial markets, including actual or potential stresses in the banking industry; (ii) changes in interest rates; (iii) the credit risks of lending activities, including our ability to estimate credit losses and the allowance for credit losses, as well as the effects of changes in the level of, and trends in, loan delinquencies and write-offs; (iv) effectiveness of our data security controls in the face of cyber attacks and any reputational risks following a cybersecurity incident; (v) changes in general business, industry or economic conditions or competition; (vi) changes in any applicable law, rule, regulation, policy, guideline or practice governing or affecting financial holding companies and their subsidiaries or with respect to tax or accounting principles or otherwise; (vii) adverse economic effects from international trade disputes, including threatened or implemented tariffs imposed by the U.S. and threatened or implemented tariffs imposed by foreign countries in retaliation, or similar events impacting economic activity; (viii) higher than expected costs or other difficulties related to integration of combined or merged businesses; (ix) the effects of business combinations and other acquisition transactions, including the inability to realize our loan and investment portfolios; (x) changes in the quality or composition of our loan and investment portfolios; (xi) adequacy of loan loss reserves; (xii) increased competition; (xiii) loss of certain key officers; (xiv) deposit attrition; (xv) rapidly changing technology; (xvi) unanticipated regulatory or judicial proceedings and liabilities and other costs; (xvii) changes in the cost of funds, demand for loan products or demand for financial services; and (xviii) other economic, competitive, governmental or technological factors affecting our operations, markets, products, services and prices. Such developments could have an adverse impact on the Corporation's financial position and results of operations. For more information about factors that could cause actual results to differ from those discussed in the forward-looking statements, please refer to the “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” sections of and the forward-looking statement disclaimers in the Corporation’s annual and quarterly reports filed with the Securities and Exchange Commission. The forward-looking statements contained in this presentation are based upon management’s beliefs and assumptions and are made as of the date of this presentation. Factors or events that could cause the Corporation’s actual results to differ may emerge from time to time, and it is not possible for the Corporation to predict all of them. The Corporation undertakes no obligation to publicly update or revise any forward-looking statements included in this presentation or to update the reasons why actual results could differ from those contained in such statements, whether as a result of new information, future events or otherwise, except to the extent required by law. In light of these risks, uncertainties and assumptions, the forward-looking events discussed in this presentation might not occur and you should not put undue reliance on any forward-looking statements. NON-GAAP FINANCIAL MEASURES This presentation contains references to financial measures that are not defined in GAAP. Management uses non-GAAP financial information in its analysis of the Corporation’s performance. Management believes that these non-GAAP measures provide a greater understanding of ongoing operations, enhance comparability of results of operations with prior periods and show the effects of significant gains and charges in the periods presented. The Corporation’s management believes that investors may use these non-GAAP measures to analyze the Corporation’s financial performance without the impact of unusual items or events that may obscure trends in the Corporation’s underlying performance. This non- GAAP data should be considered in addition to results prepared in accordance with GAAP, and is not a substitute for, or superior to, GAAP results. Limitations associated with non-GAAP financial measures include the risks that persons might disagree as to the appropriateness of items included in these measures and that different companies might calculate these measures differently. Non-GAAP measures reflected within the presentation include: Return on average tangible common equity, Adjusted return on average tangible common equity, Adjusted basic earnings per common share, Adjusted diluted earnings per common share, Adjusted net income available to common shareholders, Adjusted return on average assets, Net interest margin (fully tax equivalent basis), Efficiency ratio (fully tax equivalent), Adjusted efficiency ratio (fully tax equivalent), Tangible common equity/tangible assets, Merger transaction related expenses, net of tax, Adjusted return on average equity, Tangible book value per common share. Note: GAAP stands for Generally Accepted Accounting Principles

30 INTEREST RATE SENSITIVITY (1) The graph demonstrates the annualized result of an interest rate simulation and the estimated effect that a parallel interest rate shift, or "shock," in the yield curve and subjective adjustments in deposit pricing might have on the Corporation's projected net interest income over the next 12 months. This simulation assumes that there is no growth in interest-earning assets or interest-bearing liabilities over the next 12 months. The changes to net interest income shown above are in compliance with CNB's policy guidelines.

35 NON-GAAP RECONCILIATION This presentation contains references to financial measures that are not defined in GAAP. Management uses non-GAAP financial information in its analysis of the Corporation’s performance. Management believes that these non-GAAP measures provide a greater understanding of ongoing operations, enhance comparability of results of operations with prior periods and show the effects of significant gains and charges in the periods presented. The Corporation’s management believes that investors may use these non-GAAP measures to analyze the Corporation’s financial performance without the impact of unusual items or events that may obscure trends in the Corporation’s underlying performance. This non-GAAP data should be considered in addition to results prepared in accordance with GAAP, and is not a substitute for, or superior to, GAAP results. Limitations associated with non-GAAP financial measures include the risks that persons might disagree as to the appropriateness of items included in these measures and that different companies might calculate these measures differently. A reconciliation of these non-GAAP financial measures is provided below (dollars in thousands, except per share data).
