CNB Financial (NASDAQ: CCNE) boosts Q2 2026 profit and margin after ESSA deal

Rhea-AI Filing Summary

CNB Financial Corporation reported strong second-quarter 2026 results, with net income available to common shareholders of $27.2 million, or $0.91 per diluted share, up from $26.0 million, or $0.88, in the prior quarter and $12.9 million, or $0.61, a year earlier. For the first six months of 2026, net income available to common shareholders was $53.2 million, or $1.79 per diluted share, compared with $23.3 million, or $1.10, for the same period in 2025, driven by higher net interest income, increased non-interest income, and the impact of the ESSA acquisition.

Total revenue for the quarter was $87.6 million, versus $83.3 million in Q1 2026 and $61.2 million in Q2 2025. Net interest income rose to $76.3 million, and the net interest margin improved to 3.88% (3.89% on a fully tax-equivalent basis). Pre-provision net revenue reached $36.9 million, and the efficiency ratio on a fully tax-equivalent basis improved to 56.14%. Loans totaled $6.4 billion excluding $93.9 million of syndicated balances, with organic loan growth of $64.3 million in the quarter, while deposits were $7.1 billion; excluding the deliberate exit of a $140.0 million higher-cost municipal relationship, deposits increased $71.6 million and noninterest-bearing deposits grew $22.7 million.

Asset quality metrics remain manageable but showed some pressure: nonperforming assets were $58.4 million, or 0.69% of total assets, up from $49.2 million (0.58%) at March 31, 2026 and $30.4 million (0.48%) a year earlier, with net loan charge-offs of $1.4 million, or 0.09% annualized of average loans. The allowance for credit losses was 1.04% of total loans, and coverage of nonaccrual loans was 123.00%. Capital and liquidity are solid, with total shareholders’ equity of $909.4 million, common shareholders’ equity to total assets of 10.10%, tangible common equity to tangible assets of 8.81%, and estimated liquidity sources of about 4.8 times adjusted uninsured deposits, while all regulatory capital ratios remain above “well-capitalized” thresholds.

Positive

• Net income available to common shareholders reached $27.2 million ($0.91 per diluted share) in Q2 2026, up from $12.9 million ($0.61) in Q2 2025, reflecting stronger earnings power and contribution from the ESSA acquisition.
• Total revenue was $87.6 million in Q2 2026 versus $61.2 million a year earlier, as net interest income increased to $76.3 million and the fully tax-equivalent net interest margin improved to 3.89%.
• Capital and balance sheet strength remained solid, with total shareholders’ equity of $909.4 million, a common equity-to-assets ratio of 10.10%, tangible common equity to tangible assets of 8.81%, and all regulatory capital ratios above “well-capitalized” levels.

Negative

• Asset quality weakened somewhat as nonperforming assets rose to $58.4 million, or 0.69% of total assets, from $30.4 million (0.48%) a year earlier, and allowance coverage of nonaccrual loans declined to 123.00% from higher prior-period levels.

Filing Explained

As of June 30, 2026, CNB had completed a $50 million subordinated-note redemption, leaving $35 million outstanding at a floating rate.

The Form 8-K records two balance-sheet changes: a completed partial redemption of $50.0 million of subordinated notes and $81.3 million of deposits classified as held for sale.

The filing is a material-event report, and the debt action is complete rather than proposed: $35.0 million of the notes remains outstanding, with interest resetting quarterly to three-month average SOFR plus 2.58%.

The deposits held for sale are associated with a planned sale of certain customer accounts as part of a broader initiative to optimize the company’s branch and market footprint following the ESSA acquisition; the filing does not state that this sale has closed.

5 terms

pre-provision net revenue financial

"Pre-provision net revenue ("PPNR"), a non-GAAP measure, was $36.9 million for the three months ended June 30, 2026"

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.

tangible book value per common share financial

"Tangible book value per common share, a non-GAAP measure, was $24.73 as of June 30, 2026"

A per-share measure of the company’s tangible net asset value available to common shareholders after removing intangible items (like goodwill, brand value, and patents) and any preferred shareholder claims. Think of it as the amount each common share would get if the company sold only its physical and financial assets and settled priority claims. Investors use it as a conservative baseline to judge whether a stock is cheaply priced relative to the company’s hard-asset backing.

Secured Overnight Financing Rate ("SOFR") financial

"The interest rate on the remaining Subordinated Notes reset to a floating rate equal to the three-month average SOFR plus 2.58%"

A secured overnight financing rate (SOFR) is a daily benchmark interest rate that reflects the actual cost of borrowing cash overnight using U.S. Treasury securities as collateral. Investors watch SOFR because it serves as a reference for loans, bond yields and interest-rate contracts; think of it as the going overnight price to rent money—small changes in that price influence borrowing costs, investment returns and the valuation of interest-sensitive assets.

high volatility commercial real estate ("HVCRE") financial

"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"

nonperforming assets financial

"Total nonperforming assets were $58.4 million, or 0.69% of total assets, as of June 30, 2026"

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.

◦Adjusted earnings for the three months ended June 30, 2025, a non-GAAP measure, were $13.2 million, or $0.63 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 June 30, 2026 increased $14.0 million, or $0.28 per diluted share, compared to adjusted earnings for the three months ended June 30, 2025.

•Loans - Excluding $93.9 million of syndicated loan balances, loans were $6.4 billion as of June 30, 2026. During the three months ended June 30, 2026, organic loans increased by $64.3 million, or 1.01% (4.06% annualized), from March 31, 2026.1 The increase in organic loans was primarily driven by growth in commercial and industrial loans.

•Deposits - At June 30, 2026, total deposits were $7.1 billion. Including $81.3 million in deposits classified as held for sale, organic deposits declined for the quarter by $68.4 million, or 0.95% (3.80% annualized), compared to March 31, 2026.1 The second quarter of 2026 included the exit of a higher cost municipal deposit relationship totaling approximately $140.0 million, with an average interest cost of 3.49%. Excluding the impact of this exit, total deposits increased approximately $71.6 million, or 0.99% (3.97% annualized), compared to the first quarter of 2026.1 Noninterest-bearing deposits increased for the quarter by $22.7 million, or 2.01% (8.07% annualized), compared to March 31, 2026, primarily driven by treasury management customer relationships.

•Borrowings - On June 15, 2026, the Corporation completed the redemption of $50.0 million of its 3.25% Fixed-to-Floating Rate Subordinated Notes due June 15, 2031 (the “Subordinated Notes”). Upon completion of the partial redemption, $35.0 million in principal amount of the Subordinated Notes remained outstanding. The interest rate on the remaining Subordinated Notes reset to a floating rate and will reset quarterly thereafter at an annual rate equal to the then-current three-month average Secured Overnight Financing Rate ("SOFR") plus 2.58%.

•Credit Quality - Total nonperforming assets were approximately $58.4 million, or 0.69% of total assets, as of June 30, 2026, compared to $49.2 million, or 0.58% of total assets, as of March 31, 2026. The increase in nonperforming assets was primarily the result of one commercial and industrial relationship of approximately $8.5 million, as discussed in more detail below.

◦Net loan charge-offs for the three months ended June 30, 2026 were $1.4 million, or 0.09% (annualized) of average total loans and loans held for sale, compared to net loan charge-offs of $884 thousand, or 0.06% (annualized) of average total loans and loans held for sale, during the three months ended March 31, 2026.

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 $27.2 million, or $0.91 per diluted share, for the three months ended June 30, 2026, compared to $26.0 million, or $0.88 per diluted share, for the three months ended March 31, 2026, and $12.9 million, or $0.61 per diluted share, for the three months ended June 30, 2025. Earnings for June 30, 2026 increased $1.3 million, or $0.03 per diluted share, compared to earnings for the three months ended March 31, 2026. The quarterly increase in earnings was driven by higher net interest income and non-interest income, partially offset by higher non-interest expense, as discussed below.

◦Adjusted earnings for the three months ended June 30, 2025, a non-GAAP measure, were $13.2 million, or $0.63 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 June 30, 2026 increased $14.0 million, or $0.28 per diluted share, compared to adjusted earnings for the three months ended June 30, 2025, due primarily to the overall impact of the acquisition of ESSA.1

•Earnings were $53.2 million, or $1.79 per diluted share, for the six months ended June 30, 2026, compared to $23.3 million, or $1.10 per diluted share, for the six months ended June 30, 2025.

◦Adjusted earnings for the six months ended June 30, 2025, a non-GAAP measure, were $25.1 million, or $1.19 per diluted share, with adjusted earnings excluding merger transaction related expenses related to the Corporation’s acquisition of ESSA.1 Earnings for the six months ended June 30, 2026 increased $28.1 million, or $0.60 per diluted share, compared to adjusted earnings for the six months ended June 30, 2025, due primarily to the overall impact of the acquisition of ESSA.1

•At June 30, 2026, loans totaled $6.4 billion, excluding $93.9 million of syndicated loans. Organic loans increased $64.3 million, or 1.01% (4.06% annualized), compared to March 31, 2026. Excluding $1.7 billion in loans, net of estimated purchase accounting fair value adjustments, acquired in the ESSA acquisition, organic loan growth was $106.8 million, or 2.30%, compared to June 30, 2025.1 The increase in loans for the quarter ended June 30, 2026, compared to the quarter ended March 31, 2026, was primarily driven by an increased level of commercial and industrial loans. The year-over-year growth in loans as of June 30, 2026, compared to June 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 June 30, 2026, the syndicated loan portfolio totaled $93.9 million, or 1.44% of total loans, compared to $78.3 million, or 1.22% of total loans, at March 31, 2026 and $78.9 million, or 1.67% of total loans, at June 30, 2025. The increase in syndicated lending balances of $15.5 million compared to March 31, 2026 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, 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 June 30, 2026, total deposits were $7.1 billion. Including $81.3 million in deposits classified as held for sale, organic deposits declined for the quarter by $68.4 million, or 0.95% (3.80% annualized), compared to March 31, 2026.1 Excluding $1.5 billion in deposits assumed in the ESSA acquisition (net of estimated purchase accounting fair value adjustments), and including $81.3 million in deposits classified as held for sale, total deposits increased $238.9 million, or 4.37%, compared to June 30, 2025.1 Noninterest-bearing deposits increased for the quarter by $22.7 million, or 2.01% (8.07% annualized), compared to March 31, 2026, primarily driven by treasury management customer relationships. The $81.3 million in deposits classified as held for sale as of June 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. The quarter-over-quarter decrease in organic deposit balances as of June 30, 2026, compared to March 31, 2026, was driven primarily by the exit of a higher cost municipal deposit relationship totaling approximately $140.0 million (weighted average rate of 3.49%). Excluding the impact of this exit, total deposits increased approximately $71.6 million or 0.99% (3.97% annualized), compared to the first quarter of 2026.1 Additional deposit and liquidity profile details were as follows:

◦At June 30, 2026, the total estimated uninsured deposits for CNB Bank were approximately $2.1 billion, or 28.83% of total CNB Bank deposits. When 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 18.73% of total CNB Bank deposits.

▪Total estimated uninsured deposits for CNB Bank at March 31, 2026 were approximately $2.1 billion, or approximately 29.11% of total CNB Bank deposits. Excluding $32.1 million of affiliate company deposits and $808.1 million of pledged-investment collateralized deposits, adjusted total estimated uninsured deposits as of March 31, 2026 were approximately $1.3 billion, or approximately 17.54% of total CNB Bank deposits.

◦At June 30, 2026, the Corporation had $364.8 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 $6.0 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 June 30, 2026 of approximately 4.8 times the estimated amount of adjusted uninsured deposit balances discussed above.

•At June 30, 2026 and March 31, 2026, the Corporation had $164.0 million outstanding in short-term borrowings. The Corporation had no outstanding short-term borrowings at June 30, 2025. The increase in short-term borrowings at June 30, 2026 compared to June 30, 2025 was attributable to borrowings assumed with the ESSA acquisition.

◦On June 15, 2026, the Corporation completed the redemption of $50.0 million of the Subordinated Notes. Upon completion of the partial redemption, $35.0 million in principal amount of the Subordinated Notes remained outstanding. The interest rate on the remaining Subordinated Notes reset to a floating rate and will reset quarterly thereafter at an annual rate equal to the then-current three-month average SOFR plus 2.58%.

•At June 30, 2026, the Corporation's pre-tax net unrealized losses on the combined portfolios of available-for-sale and held-to-maturity securities totaled $54.8 million, or 6.02% of total shareholders' equity, compared to $51.9 million, or 5.83% of total shareholders' equity, at March 31, 2026, and $55.6 million, or 8.73% of total shareholders' equity, at June 30, 2025. The change in unrealized losses during the second quarter of 2026 compared to the first quarter of 2026, as well as for the quarter ended June 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 June 30, 2026, March 31, 2026, and June 30, 2025 if the net unrealized losses at the respective dates were fully recognized.

•Total nonperforming assets were $58.4 million, or 0.69% of total assets, as of June 30, 2026, compared to $49.2 million, or 0.58% of total assets, as of March 31, 2026, and were $30.4 million, or 0.48% of total assets, as of June 30, 2025. The increase of $9.2 million at June 30, 2026 compared to March 31, 2026 was primarily driven by one commercial and industrial relationship (specific reserve of $3.0 million). The $28.0 million increase at June 30, 2026 compared to June 30, 2025 was primarily driven by the addition of the previously discussed commercial and industrial relationship for $8.5 million, one previously disclosed commercial relationship for $6.9 million, and certain ESSA-related additions for $9.2 million. Net loan charge-offs for the three months ended June 30, 2026 were $1.4 million, or 0.09% (annualized) of average total loans and loans held for sale, compared to net loan charge-offs of $884 thousand, or 0.06% (annualized) of average total loans and loans held for sale, during the three months ended March 31, 2026, and $3.3 million, or 0.28% (annualized) of average total loans and loans held for sale, during the three months ended June 30, 2025.

•Pre-provision net revenue ("PPNR"), a non-GAAP measure, was $36.9 million for the three months ended June 30, 2026 and $34.1 million and $21.6 million for the three months ended March 31, 2026 and June 30, 2025, respectively.1 Excluding merger and integration costs, adjusted PPNR was $21.9 million for the three months ended June 30, 2025.1 The quarter-over-quarter change in PPNR was driven by higher net interest income and non-interest income, partially offset by higher non-interest expense. For the three months ended June 30, 2026, the increase compared to the three months ended June 30, 2025 was primarily attributable to stronger net interest income and non-interest income, partially offset by higher non-interest expenses. PPNR was $71.1 million for the six months ended June 30, 2026, compared to $37.5 million for the six months ended June 30, 2025.1 Excluding merger and integration costs, adjusted PPNR was $39.4 million for the six months ended June 30, 2025.1 The year-to-date 2026 PPNR when compared to the year-to-date 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.

Michael Peduzzi, President and CEO of both the Corporation and CNB Bank, stated, “Our second quarter earnings and financial position reflect several positive developments for CNB, and position us well for the future. In managing our capital and debt structure, during the second quarter, we called $50 million of subordinated debt that was going to reprice at a higher interest rate to the Corporation. Given our success in recent years in building a stronger common equity base with the combination of sound and increasing retained earnings, a common capital raise, and acquisition activities, we were well positioned to complete this substantial and cost-beneficial redemption without compromising our regulatory capital strength. Also during the quarter, we experienced favorable net growth and increased production momentum in our commercial loan portfolio, adding new relationships and expanding borrowing positions with qualitative customers in an increasingly competitive lending environment. This favorable commercial customer production, which more than offset some headwinds from increased loan prepayments, paralleled continued relationship growth in our Treasury Management activities. These volume increases in some of our core net interest income components were complemented by a favorable net interest margin, supported by a continued realized reduction in our average cost of funds. We continue to see both a sound loan pipeline and both commercial and retail deposit generation opportunities for further growth as we enter the third quarter.

Importantly, as we release these second quarter earnings, we recently celebrated the one-year anniversary of the July 23, 2025 acquisition of ESSA. As we look back on the past year, the benefit of hindsight reflects the successful addition and integration of this wonderful franchise and so many valued employees and clients. The professionalism, credit quality and system integration and efficiency expectations we had prior to and at the time of the ESSA acquisition have been and continue to be realized. With so many incredible and customer-focused leaders in our ESSA division, we see further opportunities to deliver great retail and commercial banking, and wealth management experiences, for clients in the Northeastern Pennsylvania markets served by ESSA. Our optimism is supported by the favorable growth in both existing relationship building and new clients being added across our lines of business in our other legacy divisions. Concurrent with these continuing franchise growth efforts, we remain focused on tightly managing the Corporation’s core overhead. Our efficiency ratio reflects not only the economies-of-scale cost efficiencies from the ESSA acquisition, but also process efficiencies including the greater effective use of automation as we continuously challenge how we deliver our products and services without any compromise to our security, quality, and internal control standards. Achieving positive operating leverage that leads to meaningful returns, built on a foundation of security and financial soundness, and delivered by engaged banking and wealth management professionals, remains our driving commitment."

Other Balance Sheet Highlights

•Book value per common share was $28.75, $28.06, and $27.44 at June 30, 2026, March 31, 2026, and June 30, 2025, respectively. Excluding merger transaction related expenses, book value per common share was $27.53 at June 30, 2025.1 Book value per common share for June 30, 2026 reflects an increase of $0.69, or 2.46%, compared to book value per common share at March 31, 2026. The increase in book value per common share from March 31, 2026 to June 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, excluding merger transaction related expenses, from June 30, 2025 to June 30, 2026 was primarily driven by the increase in additional paid-in capital resulting from the ESSA acquisition, together with growth in retained earnings, net of common and preferred stock dividends.1 These increases were 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.

•Tangible book value per common share, a non-GAAP measure, was $24.73, $23.97, and $25.35 as of June 30, 2026, March 31, 2026, and June 30, 2025, respectively.1 Excluding merger transaction related expenses, tangible book value per common share was $25.44 as of June 30, 2025.1 Tangible book value per common share for June 30, 2026 reflects an increase of $0.76, or 3.17%, compared to tangible book value per common share as of March 31, 2026. Adjusted tangible book value per common share (non-GAAP) decreased $0.71, or 2.79%, from June 30, 2025 to June 30, 2026, primarily due to the issuance of 8.4 million common shares as consideration for the ESSA acquisition and the addition of acquisition-related goodwill and core deposit intangibles of $43.6 million and $31.5 million, respectively, coupled with an increase in 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 These factors were partially offset by growth in retained earnings, net of common and preferred stock dividends.

Loan Portfolio Profile

•As part of its lending policy and 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 June 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 $126.3 million, or 1.94% of total loans outstanding;

▪There were two nonaccrual commercial office loans that totaled $2.1 million, or 1.64% of total commercial office loans outstanding;

▪There was one past-due commercial office loan that totaled $204 thousand, or 0.16% of the total commercial office loans outstanding; and

▪The average outstanding balance per commercial office loan was $902 thousand.

◦Commercial hospitality loans:

▪There were 150 outstanding loans, totaling $357.1 million, or 5.48% 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 $2.4 million.

◦Commercial multifamily loans:

▪There were 342 outstanding loans, totaling $547.1 million, or 8.40% of total loans outstanding;

▪There were two nonaccrual commercial multifamily loans that totaled $751 thousand, or 0.14% of total multifamily loans outstanding;

▪There were two past-due commercial multifamily loans that totaled $751 thousand, or 0.14% 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 12.65%, 12.36%, and 8.83% for the three months ended June 30, 2026, March 31, 2026 and June 30, 2025, respectively. Excluding merger transaction related expenses, annualized return on average equity was 9.06% for the three months ended June 30, 2025.1 Annualized return on average equity was 12.51% for the six months ended June 30, 2026. Annualized return on average equity was 8.18% for the six months ended June 30, 2025. Excluding merger transaction related expenses, annualized return on average equity was 8.78% for the six months ended June 30, 2025.1

•Annualized return on average tangible common equity, a non-GAAP measure, was 15.20%, 14.89% and 9.71% for the three months ended June 30, 2026, March 31, 2026, and June 30, 2025, respectively.1 Excluding merger transaction related expenses, annualized return on average tangible common equity was 9.98% for the three months ended June 30, 2025.1 Annualized return on average tangible common equity was 15.04% for the six months ended June 30, 2026. Annualized return on average tangible common equity was 8.95% for the six months ended June 30, 2025. Excluding merger transaction related expenses, annualized return on average tangible common equity was 9.66% for the six months ended June 30, 2025.1

•The Corporation's efficiency ratio was 57.86%, 59.03% and 64.73% for the three months ended June 30, 2026, March 31, 2026 and June 30, 2025, respectively, and 56.14%, 57.32% and 64.08%, 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 63.50% for the three months ended June 30, 2025.1 The linked-quarter decrease, on a fully tax-equivalent basis, represented an improvement of 118 basis points compared to March 31, 2026, primarily driven by higher net interest income and non-interest income, 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 58.43% for the six months ended June 30, 2026, and 56.71% on a fully tax-equivalent basis, a non-GAAP measure.1 The Corporation's efficiency ratio was 68.27% for the six months ended June 30, 2025, and 67.55% 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 65.97% for the six months ended June 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 $87.6 million for the three months ended June 30, 2026, compared to $83.3 million and $61.2 million for the three months ended March 31, 2026 and June 30, 2025, respectively.

◦Net interest income was $76.3 million for the three months ended June 30, 2026, compared to $73.3 million and $52.2 million for the three months ended March 31, 2026 and June 30, 2025, respectively. When comparing the second quarter of 2026 to the first quarter of 2026, the increase in net interest income of $3.0 million, or 4.12% (16.53% annualized), was primarily due to higher purchase accounting loan accretion, increased investment income, and higher interest income earned on excess cash balances maintained in the interest-bearing reserve account at the Federal Reserve. Net interest income increased $24.1 million, or 46.26%, for the three months ended June 30, 2026, compared to the three months ended June 30, 2025, primarily reflecting the impact of the ESSA acquisition and growth in the Corporation's legacy loan portfolio.

◦Net interest margin was 3.88%, 3.83%, and 3.60% for the three months ended June 30, 2026, March 31, 2026, and June 30, 2025, respectively. Net interest margin on a fully tax-equivalent basis, a non-GAAP measure, was 3.89%, 3.84% and 3.59% for the three months ended June 30, 2026, March 31, 2026, and June 30, 2025, respectively.1 Excluding the $4.8 million and $3.0 million in purchase accounting loan accretion in the second quarter of 2026 and first quarter of 2026, respectively, the net interest margin on a fully tax-equivalent basis for the three months ended June 30, 2026 and March 31, 2026 was 3.65% and 3.68%, respectively.1

▪The yield on earning assets of 5.88% for the three months ended June 30, 2026 increased 3 basis points compared to the three months ended March 31, 2026 and decreased 1 basis point compared to the three months ended June 30, 2025. The increase in yield in the second quarter of 2026 compared to the quarter ended March 31, 2026 was primarily attributable to an increase in purchase accounting loan accretion. The decrease in yield during the second quarter of 2026 compared to the second quarter of 2025 was primarily attributable to lower average loan yields resulting from the three Federal Reserve rate cuts.

▪The cost of interest-bearing liabilities was 2.50% for the three months ended June 30, 2026, reflecting decreases of 2 basis points and 38 basis points from the three months ended March 31, 2026 and the three months ended June 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, coupled with the benefit of ESSA’s lower overall interest cost of deposits.

•Total revenue was $171.0 million for the six months ended June 30, 2026 compared to $118.1 million for the six months ended June 30, 2025.

◦Net interest income was $149.7 million for the six months ended June 30, 2026 compared to $100.6 million for the six months ended June 30, 2025. When comparing the six months ended June 30, 2026 to the six months ended June 30, 2025, the increase in net interest income of $49.0 million, or 48.73% (98.27% annualized), was primarily due to the impact of the ESSA acquisition.

◦Net interest margin was 3.86% and 3.49% for the six months ended June 30, 2026 and June 30, 2025, respectively. Net interest margin on a fully tax-equivalent basis, a non-GAAP measure, was 3.86% and 3.48% for the six months ended June 30, 2026 and June 30, 2025, respectively.1 Excluding the $7.8 million in purchase accounting loan accretion for the six months ended June 30, 2026, the net interest margin on a fully tax-equivalent basis was 3.66%.1

▪The yield on earning assets of 5.86% for the six months ended June 30, 2026 increased 5 basis points from June 30, 2025. The increase in yield compared to June 30, 2025 was attributable to growth in higher-yielding securities, coupled with the impact from the ESSA acquisition, partially offset by three Federal Reserve rate decreases totaling 75 basis points since mid-September 2025.

▪The cost of interest-bearing liabilities of 2.51% for the six months ended June 30, 2026 decreased 39 basis points from June 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 $11.3 million for the three months ended June 30, 2026, compared to $10.0 million and $9.0 million for the three months ended March 31, 2026 and June 30, 2025, respectively. The quarter-over-quarter increase was primarily attributable to higher net realized and unrealized gains on equity securities, and an increase in wealth and asset management fees, partially offset by a decrease in net realized gains on available-for-sale securities. The year-over-year increase in non-interest income was primarily driven by increases in wealth and asset management fees, card processing and interchange income, and higher service charges on deposits.

•Total non-interest income was $21.3 million for the six months ended June 30, 2026 compared to $17.5 million for the six months ended June 30, 2025. This increase was primarily due to higher wealth and asset management fees, card processing and interchange 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 June 30, 2026, March 31, 2026, and June 30, 2025, total non‑interest expense was $50.7 million, $49.2 million, and $39.6 million, respectively. Excluding merger and integration costs, total non‑interest expense for the three months ended June 30, 2025 was $39.3 million.1 The quarter-over-quarter increase of $1.5 million, or 3.09%, was primarily driven by increases in state and local taxes, FDIC insurance premiums, and other non-interest expenses, including the timing of business development-related costs, partially offset by lower salaries and employee benefits expense. The increase in state and local taxes was primarily due to an $852 thousand sales tax refund recognized during the three months ended March 31, 2026. The decrease in salaries and employee benefits expense reflected disciplined hiring as the Corporation continues to integrate employees and operational processes associated with the ESSA acquisition, as well as lower incentive compensation accruals resulting from reduced anticipated payout levels. Excluding merger and integration costs, the $11.4 million, or 29.16%, increase in non-interest expense compared to the three months ended June 30, 2025 was primarily attributable to personnel, occupancy and facilities costs, software licensing expenses, higher core system volume-based fees, and other operating costs associated with the ESSA acquisition.

•For the six months ended June 30, 2026 total non-interest expense was $99.9 million compared to $80.7 million for the six months ended June 30, 2025. Excluding merger and integration costs, total non‑interest expense for the six months ended June 30, 2025 was $78.8 million.1 Excluding merger and integration costs, the increase of $21.1 million, or 26.82%, compared to the six months ended June 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 June 30, 2026 was $6.9 million, representing a 19.50% effective tax rate, compared to $6.1 million, representing an 18.41% effective tax rate, for the three months ended March 31, 2026, and $3.3 million, representing a 19.10% effective tax rate, for the three months ended June 30, 2025. Income tax expense for the six months ended June 30, 2026 was $13.0 million, representing an 18.97% effective tax rate, compared to $6.2 million, representing a 19.49% effective tax rate, for the six months ended June 30, 2025.

Asset Quality

•Total nonperforming assets were $58.4 million, or 0.69% of total assets, as of June 30, 2026, compared to $49.2 million, or 0.58% of total assets, as of March 31, 2026, and $30.4 million, or 0.48% of total assets, as of June 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 June 30, 2026, compared to 1.04% as of March 31, 2026, and 1.02% as of June 30, 2025. In addition, the allowance for credit losses as a percentage of nonaccrual loans was 123.00% as of June 30, 2026, compared to 145.33% and 169.52% as of March 31, 2026 and June 30, 2025, respectively.

•The provision for credit losses was $1.8 million for the three months ended June 30, 2026, compared to $998 thousand for the three months ended March 31, 2026, and $4.3 million for the three months ended June 30, 2025. The $779 thousand quarter-over-quarter increase in the provision for credit losses was primarily driven by a charge-off of one commercial loan (balance of approximately $2.4 million with a specific reserve balance of $1.2 million) that was transferred to other real estate owned, as well as continued loan portfolio growth. The $2.6 million decrease compared to the three months ended June 30, 2025, was primarily attributable to two previously disclosed commercial real estate charge-offs recognized during the second quarter of 2025. The provision for credit losses was $2.8 million for the six months ended June 30, 2026, compared to $5.9 million for the six months ended June 30, 2025. The $3.1 million decrease in the provision for credit losses compared to the six months ended June 30, 2025, was primarily attributable to two previously disclosed commercial real estate charge-offs recognized during the prior-year period.

•As discussed in more detail above, for the three months ended June 30, 2026, net loan charge-offs were $1.4 million, or 0.09% (annualized) of average total loans and loans held for sale, compared to $884 thousand, or 0.06% (annualized) of average total loans and loans held for sale, during the three months ended March 31, 2026, and $3.3 million, or 0.28% (annualized) of average total loans and loans held for sale, during the three months ended June 30, 2025. Net loan charge-offs were $2.3 million, or 0.07% (annualized) for the six months ended June 30, 2026, compared to $4.7 million, or 0.21% (annualized) for the six months ended June 30, 2025.

Capital

•As of June 30, 2026, the Corporation’s total shareholders’ equity was $909.4 million, representing an increase of $20.3 million, or 2.29%, from March 31, 2026, and an increase of $272.2 million, or 42.71%, from June 30, 2025. The quarter-over-quarter increase was primarily driven by growth in retained earnings of $21.6 million, net of the payment of common and preferred stock dividends, partially offset by a $2.3 million increase in accumulated other comprehensive loss. The year-over-year increase was primarily driven by a $206.1 million increase in additional paid-in capital related to the ESSA acquisition, growth in retained earnings of $69.9 million, net of the payment of common and preferred stock dividends, partially offset by a $3.1 million increase in accumulated other comprehensive loss, during the twelve months ended June 30, 2026.

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

•As of June 30, 2026, the Corporation’s ratio of common shareholders' equity to total assets was 10.10% compared to 9.76% at March 31, 2026 and 9.17% at June 30, 2025. As of June 30, 2026, March 31, 2026, and June 30, 2025, the Corporation’s ratio of tangible common equity to tangible assets, a non-GAAP measure, was 8.81%, 8.46%, and 8.53%, respectively.1 Excluding merger transaction related expenses, the Corporation’s ratio of tangible common equity to tangible assets, a non-GAAP measure, as of June 30, 2025 was 8.56%.1 The increase in the ratio of tangible common equity to tangible assets compared to June 30, 2025 was primarily the result of an increase in retained earnings (net of the payment of common and preferred stock dividends), partially offset with an increase in accumulated other comprehensive loss, and the impacts of the ESSA acquisition.

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 June 30, 2026 are estimated pending final regulatory filings.

(2) Average yields are stated on a fully taxable equivalent basis (calculated using statutory rates of 21%) resulting from tax-free municipal securities in the investment portfolio and tax-free municipal loans in the commercial loan portfolio. The taxable equivalent adjustment to net interest income for the three months ended June 30, 2026, March 31, 2026 and June 30, 2025 was $497 thousand, $398 thousand and $265 thousand, respectively.

(3) Average loans receivable outstanding includes the average balance outstanding of all nonaccrual loans. Loans receivable consists of the average of total loans receivable less average unearned income. In addition, loans receivable interest income consists of loans receivable fees.

(4) Average balance is computed using the fair value of AFS securities and amortized cost of HTM securities. Average yield has been computed using amortized cost average balance for AFS and HTM securities. The adjustment to the average balance for securities in the calculation of average yield for the three months ended June 30, 2026, March 31, 2026 and June 30, 2025 was $(40.2) million, $(32.2) million and $(42.6) million, respectively.

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).

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.

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.

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 report 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.

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. ▪ Earnings stability across declining and rising rate environments ▪ Interest rate sensitivity based primarily on organic balance sheet execution (no external hedging utilized) 3/31/2026 12/31/2025 +300 basis points 0.4% 1.6% +200 basis points 0.7% 1.5% +100 basis points 0.5% 1.0% -100 basis points -0.9% -1.8% -200 basis points -0.1% -2.0% -300 basis points 0.6% -2.8% % Change in Net Interest Income (1)

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).
