PEOPLES BANCORP INC. ANNOUNCES RESULTS FOR THE SECOND QUARTER 2026

_____________________________________________________________________

MARIETTA, Ohio - Peoples Bancorp Inc. ("Peoples") (NASDAQ: PEBO) today announced results for the quarter ended June 30, 2026. Net income totaled $28.0 million for the second quarter of 2026, representing earnings per diluted common share of $0.78. In comparison, Peoples reported net income of $29.0 million, representing earnings per diluted common share of $0.81, for the first quarter of 2026 and net income of $21.2 million, representing earnings per diluted common share of $0.59, for the second quarter of 2025. Non-core items, which includes one-time losses and expenses, negatively impacted earnings per diluted common share by $0.18 for the second quarter of 2026, $0.01 for the first quarter of 2026, and $0.01 for the second quarter of 2025.

"We are pleased with the results for the second quarter of 2026, with improvements in many performance metrics including our net interest margin expanding seven basis points for the quarter," said Tyler Wilcox, President and Chief Executive Officer. "We are committed to maintaining our focus on delivering strong returns and driving shareholder value."

Citizens Acquisition:

On April 21, 2026, Peoples announced the signing of a definitive agreement and plan of merger pursuant to which Peoples will acquire Citizens, a bank holding company headquartered in Paintsville, Kentucky, and the parent company of Citizens Bank of Kentucky, Inc. (“Citizens Bank”), in a cash and stock transaction. Under the terms of the Merger Agreement, Citizens will merge with and into Peoples (the “Merger”), and Citizens Bank will subsequently merge with and into Peoples’ wholly owned subsidiary, Peoples Bank, in a transaction valued at approximately $76.6 million. As of June 30, 2026 Peoples had recognized $0.4 million in acquisition-related expenses associated with this pending transaction.

Quarterly Highlights:

•Net interest margin for the second quarter of 2026 increased to 4.23% when compared to 4.16% for the linked quarter driven by a reduction in deposit costs.

◦Net interest income increased $2.3 million compared to the linked quarter and was driven by lower funding costs.

•Provision for credit losses decreased $5.0 million when compared to the linked quarter.

◦Net charge-offs decreased from $6.6 million for the linked quarter to $5.2 million for the second quarter of 2026. As a percentage of average total loans on an annualized basis, this represents a 9 basis point improvement. The improvement was driven by reductions in charge-offs in leases and indirect consumer loans.

◦The provision for credit losses was also positively impacted by the stabilization of macro-economic conditions used within the current expected credit losses ("CECL") model.

◦Period-end total loan and lease balances at June 30, 2026, increased $51.4 million, or 3% annualized, when compared to the linked quarter.

◦The loan growth was largely due to increases in commercial and industrial loans, driven by life premium finance loans, commercial premium finance loans, and construction loans, which were partially offset by a decrease in other commercial real estate loans.

1

•Total non-interest income, excluding net gains and losses, increased $0.3 million, or 1%, for the second quarter of 2026 compared to the linked quarter.

◦The growth was driven by increases in electronic banking income, lease income, trust and investment income, and mortgage banking income. These increases were partially offset by lower insurance income, which was driven by the annual performance-based commissions recognized in the first quarter of each year.

•Tangible book value per common share for the second quarter of 2026 increased to $23.56 when compared to $22.95 for the linked quarter.

Net Interest Income

Net interest income was $92.7 million for the second quarter of 2026, which was an increase of $2.3 million compared to the linked quarter. Net interest margin was 4.23% for the second quarter of 2026, compared to 4.16% for the linked quarter. The increase in net interest income and net interest margin was primarily driven by a reduction in deposit costs compared to the linked quarter.

Net interest income for the second quarter of 2026 increased $5.2 million, or 6%, compared to the second quarter of 2025. Net interest margin increased 8 basis points when compared to the second quarter of 2025. The increases in net interest income and net interest margin were primarily driven by lower deposit and borrowing costs compared to the second quarter of 2025.

Accretion income, net of amortization expense, from acquisitions was $1.1 million for the second quarter of 2026, $1.3 million for the linked quarter and $2.6 million for the second quarter of 2025, which added 5 basis points, 6 basis points and 12 basis points, respectively, to net interest margin. The decrease in accretion income for the second quarter of 2026 when compared to the linked quarter and second quarter of 2025 was driven by less accretion income recognized in the current period from the 2023 merger with Limestone Bancorp, Inc. (the "Limestone Merger").

For the first six months of 2026, net interest income increased $10.3 million compared to the same period of 2025, while net interest margin increased 6 basis points to 4.20%. The increases in net interest income and net interest margin were driven by lower deposit costs and increased interest income compared to the first half of 2025.

Accretion income, net of amortization expense, was $2.4 million for the first six months of 2026, compared to $6.1 million of accretion income recognized in the first half of 2025. Accretion income contributed 6 basis points and 15 basis points to net interest margin in the first six months of 2026 and 2025, respectively.

Provision for Credit Losses:

The provision for credit losses was $4.7 million for the second quarter of 2026, compared to $9.7 million for the linked quarter, and $16.6 million for the second quarter of 2025. The provision for credit losses for the second quarter of 2026 was driven by the reduction of balances within higher loss rate segments offset by an increase in individually-analyzed loans. The provision for credit losses for the linked quarter was primarily driven by net charge-offs and a deterioration in macro-economic conditions used within the CECL model. The provision for credit losses for the second quarter of 2025 was primarily driven by (i) net charge-offs, (ii) an increase in reserves for individually analyzed loans and leases, (iii) an increase in reserves for leases originated by the North Star Leasing division, (iv) a periodic refresh in loss drivers utilized within the CECL model, (v) deterioration in the economic forecasts used within the CECL model, and (vi) loan growth.

The provision for credit losses during the first six months of 2026 was $14.4 million and was primarily driven by net charge-offs, a deterioration in macro-economic conditions used within the CECL model, and an increase in individually- analyzed loans. The provision for credit losses for the same period of 2025 was $26.8 million and was driven by (i) net charge-offs, (ii) an increase in reserves for individually-analyzed loans and leases, (iii) an increase in reserves for leases originated by the North Star Leasing division, (iv) a periodic refresh in the loss drivers utilized within the CECL model, (v) deterioration in the economic forecasts used within the CECL model, and (vi) loan growth.

The provision for credit losses recorded represents the amount needed to maintain the appropriate level of the allowance for credit losses based on management’s quarterly estimates. The provision for credit losses negatively impacted earnings per diluted common share by $0.10 for the second quarter of 2026, $0.21 for the first quarter of 2026, and $0.36 for the second quarter of 2025. The provision for credit losses negatively impacted earnings per diluted common share by $0.31 and $0.59 for the first half of 2026 and 2025, respectively.

For additional information on net charge-offs, credit trends and the allowance for credit losses, see the "Asset Quality" section below.

Net Gains and Losses:

Net gains and losses include gains and losses on investment securities, asset disposals and other transactions, which are included in total non-interest income on the Consolidated Statements of Income. The net loss for the second quarter of 2026 was $8.6 million, compared to a net loss of $0.4 million for the linked quarter, and a net loss of $0.3 million for the second quarter of 2025. The net loss for the second quarter of 2026 was driven by the sale of $135.2 million of available-for-sale securities at a net loss of $8.2 million due to a portfolio restructure as Peoples manages its balance sheet under $10

2

billion in assets ahead of the pending Citizens merger. The net losses for the linked quarter and the second quarter of 2025 were driven by net losses on repossessed assets.

The net losses realized during the first half of 2026 and 2025 were $9.0 million and $0.6 million, respectively. The net loss for the first half of 2026 was driven by the aforementioned investment portfolio restructure in the second quarter. The net loss for the first half of 2025 was driven by losses on repossessed assets.

Total Non-interest Income, Excluding Net Gains and Losses:

Total non-interest income, excluding net gains and losses, for the second quarter of 2026 increased $0.3 million compared to the linked quarter. The increase in non-interest income, excluding net gains and losses, was primarily impacted by increases of $0.6 million in electronic banking income, driven by debit card interchange, $0.4 million in lease income, driven by an increase in month-to-month income, $0.4 million in trust and investment income, and $0.2 million in mortgage banking income. Partially offsetting those increases was a decrease of $1.2 million in insurance income due to the seasonal performance-based commissions recognized in the first quarter of each year. Total non-interest income, excluding net gains and losses, for the second quarter of 2026 was 24% of total revenue (defined as net interest income plus total non-interest income excluding net gains and losses), consistent with the linked quarter.

Compared to the second quarter of 2025, total non-interest income, excluding net gains and losses, increased $1.8 million due to increases of $0.8 million in lease income, driven by higher operating lease income, $0.7 million in trust and investment income, driven by an increase in assets under administration and management, $0.4 million in deposit account services charges, and $0.4 million in mortgage banking income, partially offset by a decrease of $0.6 million in other non-interest income, driven by lower swap fee income.

During the first six months of 2026, total non-interest income, excluding gains and losses, increased $3.0 million, or 6%, when compared to the same period of 2025. The increase was primarily due to increases of $1.9 million in lease income, driven by operating lease income, $1.2 million in trust and investment income, driven by an increase in assets under administration and management, and $0.7 million in deposit account service charges, partially offset by a decrease of $0.8 million in other non-interest income, driven by lower swap fee income.

Total Non-interest Expense:

Total non-interest expense increased $1.1 million for the second quarter of 2026, compared to the linked quarter. The increase in total non-interest expense was primarily due to increases of $1.3 million in professional fees, driven by higher legal expenses and professional services, and $0.3 million in data processing and software expense, which were partially offset with a decrease of $0.5 million in net occupancy and equipment expense, driven by lower repair and maintenance costs.

Compared to the second quarter of 2025, total non-interest expense increased $2.4 million. The increase in total non-interest expense was primarily driven by increases of $1.1 million in salaries and benefit costs due to higher sales levels and overall company performance measures used in calculating incentive awards, $0.7 million in operating lease expense, $0.5 million in data processing and software expense due to costs associated with recent technology projects, and $0.4 million in professional fees, partially offset by a decrease of $0.5 million in amortization of other intangible assets, driven by decreases in amortization on core deposits and customer relationship intangibles.

For the first six months of 2026, total non-interest expense increased $3.2 million, when compared to the same period of 2025. This increase was primarily driven by increases of $1.6 million in operating lease expense, $1.1 million in salaries and employee benefit costs due to annual merit increases and an increase in sales incentives, $1.0 million in data processing and software expenses driven by recent technology projects, and $0.7 million in net occupancy and equipment expense, partially offset by a decrease of $1.0 million in amortization of other intangible assets, due to decreases in amortization on core deposits and customer relationship intangibles.

The efficiency ratio for the second quarter of 2026 was 58.3%, compared to 58.6% for the linked quarter and 59.3% for the second quarter of 2025. The efficiency ratio improved slightly compared to the linked quarter mainly as the result of higher revenue. The efficiency ratio for the first six months of 2026 was 58.4%, compared to 60.0% for the same period of

4

2025. The efficiency ratio improved compared to the same period of 2025 due to higher revenue. The efficiency ratio adjusted for non-core items was 57.9% for the second quarter of 2026. Peoples continues to focus on controlling expenses, while recognizing necessary costs in order to continue growing the business.

Income Tax Expense:

Peoples recorded income tax expense of $7.7 million with an effective tax rate of 21.6% for the second quarter of 2026, compared to income tax expense of $8.3 million with an effective tax rate of 22.3% for the linked quarter and income tax expense of $6.2 million with an effective tax rate of 22.7% for the second quarter of 2025. Income tax expense for the first six months of 2026 and 2025 was $16.0 million and $13.3 million, with an associated effective tax rate of 22.0% and 22.6%, respectively. The decreases in income tax expense and the effective tax rate when compared to the linked quarter were impacted by a $0.5 million benefit relating to tax credits purchased in the second quarter of 2026. The increase in income tax expense when compared to the three and six month periods ended June 30, 2025, was driven by higher pretax income.

Investment Securities and Liquidity:

Peoples' investment portfolio primarily consists of available-for-sale investment securities reported at fair value and held-to-maturity investment securities reported at amortized cost. The available-for-sale investment securities balance at June 30, 2026, decreased $133.9 million when compared to at March 31, 2026, decreased $110.3 million when compared to December 31, 2025, and decreased $177.4 million when compared to at June 30, 2025. The decrease in available-for-sale investment securities compared to all prior periods was driven by the aforementioned portfolio restructure. The unrealized losses, net of tax, on available-for-sale investment securities recognized within accumulated other comprehensive loss were $71.2 million at June 30, 2026, $76.4 million at March 31, 2026, $71.0 million at December 31, 2025, and $90.9 million at June 30, 2025. The decrease in accumulated other comprehensive loss compared to the linked quarter was the result of sales of available-for-sale investment securities during the period. At June 30, 2026, Peoples’ investment securities represented approximately 19.1% of total assets, compared to 20.3% at March 31, 2026, 20.5% at December 31, 2025, and 21.2% at June 30, 2025. The decrease in the percentage of investment securities to total assets was impacted in the second quarter of 2026 by sales of available-for-sale investment securities.

The held-to-maturity investment securities balance at June 30, 2026, decreased $16.3 million when compared to at March 31, 2026, decreased $55.5 million when compared to at December 31, 2025, and decreased $32.7 million when compared to at June 30, 2025. The decrease when compared to all prior periods was due to prepayments and maturities of collateralized mortgage obligations.

The effective durations of the available-for-sale investment securities and the held-to-maturity investment securities as of June 30, 2026, were approximately 6.03 and 7.55 years, respectively. The duration of Peoples’ investments is managed as part of Peoples' Asset Liability Management program, and has the potential to impact both liquidity and capital, as mismatches in duration may require a liquidation of investment securities at market prices to meet funding needs. These assets are a component of Peoples' liquidity profile.

Peoples maintains a number of liquid and liquefiable assets, borrowing capacity, and other sources of liquidity to ensure the availability of funds. At June 30, 2026, Peoples had liquid and liquefiable assets totaling $549.5 million, which included (i) cash and cash equivalents, (ii) unpledged government and agency investment securities and (iii) unpledged non-agency investment securities that could be liquidated. At June 30, 2026, Peoples had a total borrowing capacity of $848.7 million available through the Federal Home Loan Bank (“FHLB”), the Federal Reserve Bank ("FRB"), and federal funds. Additionally, at June 30, 2026, Peoples had contingent sources of liquidity totaling $3.9 billion. Contingent sources of liquidity are generally comprised of borrowing capacity at the FHLB and FRB, unpledged securities, liquifiable securities, and available capacity from wholesale funding sources. Cash and cash equivalents decreased $9.2 million when compared to December 31, 2025, as the level of cash fluctuates given Peoples' total liquidity position.

Loans and Leases:

The period-end total loan and lease balances at June 30, 2026, increased $51.4 million, or 3% annualized, compared to at March 31, 2026. The increase in loans was driven by increases of $43.0 million in commercial and industrial loans, driven largely by life premium finance loans, $37.1 million in commercial premium finance loans, and $24.8 million in construction loans, partially offset by decreases of $57.7 million in other commercial real estate loans and $10.6 million in leases originated by the North Star Leasing division.

Total loans and leases increased by $64.7 million, or 2% annualized, when compared to at December 31, 2025. The increase was driven by increases of $154.1 million in commercial and industrial loans and $20.1 million in home equity lines of credit, partially offset by decreases of $80.8 million in other commercial real estate loans, $15.2 million in residential real estate loans, and $11.7 million in leases.

The period-end total loan and lease balances at June 30, 2026, increased $220.0 million, or 3%, compared to at June 30, 2025, driven by increases of $282.4 million in commercial and industrial loans, $34.9 million in other commercial real estate loans, and $32.2 million home equity lines of credit. These increases were partially offset by decreases of $47.0 million in construction loans, $46.1 million in leases, and $31.5 million in residential real estate loans.

Quarterly average total loan balances increased $39.4 million compared to the linked quarter and $331.1 million when compared to the prior year quarter. The increase in average total loan balances when compared to the linked quarter was primarily the result of increases of $98.0 million in commercial and industrial loans and $11.3 million in home equity lines of credit, partially offset by decreases of $46.9 million in other commercial real estate loans, and $15.1 million in residential real estate loans. The increase in average total loans when compared to the prior year quarter was driven by increases in $326.8 million commercial and industrial loans, $94.1 million in other commercial real estate loans, and $28.4 million in home equity lines of credit, partially offset by decreases of $52.5 million, $31.5 million, and $30.9 million in construction loans, leases, and residential real estate loans, respectively.

For the first six months of 2026, the average total loans balances increased $355.8 million compared to the first six months of 2025. The increase in average total loan balances was primarily the result of increases of $273.1 million in commercial and industrial loans, $138.2 million in other commercial real estate loans, and $25.7 million in home equity lines of credit, partially offset by decreases of $37.9 million and $35.4 million in construction loans and leases, respectively.

Asset Quality:

Key asset quality metrics improved in some regards during the second quarter of 2026. Delinquency trends improved as loans considered current comprised 99.1%, 98.9%, and 99.1% of the loan portfolio at June 30, 2026, at March 31, 2026, and at June 30, 2025, respectively. Total nonperforming assets at June 30, 2026, increased $1.4 million, or 4%, compared to at March 31, 2026, and decreased $5.6 million, or 12%, compared to at June 30, 2025. The increase in nonperforming assets compared to at March 31, 2026, was driven by two other commercial real estate loans totaling $3.8 million that were 90+ days past due and accruing at the end of the current quarter. Compared to at June 30, 2025, nonperforming assets decreased because of the sale of an OREO property in the fourth quarter of 2025. Nonperforming assets as a percent of total loans and OREO was 0.60% at June 30, 2026, compared to 0.59% at March 31, 2026, and 0.71% at June 30, 2025.

Criticized loans, which are those categorized as special mention, substandard or doubtful, increased $49.7 million, or 22%, compared to at March 31, 2026, and increased $29.3 million, or 12%, compared to at June 30, 2025. As a percent of total loans, criticized loans were 4.01% at June 30, 2026, compared to 3.31% at March 31, 2026, and 3.70% at June 30, 2025. The increase in the amount of criticized loans compared to at March 31, 2026, and at June 30, 2025, was driven by fewer paydowns on loans previously considered criticized, coupled with an increase in loan downgrades, driven by two larger commercial downgrades during the quarter.

Classified loans, which are those categorized as substandard or doubtful, decreased $1.1 million, or 1%, compared to at March 31, 2026, and increased $15.8 million, or 13%, compared to at June 30, 2025. As a percent of total loans, classified loans were 2.06% at June 30, 2026, compared to 2.10% at March 31, 2026, and 1.89% at June 30, 2025. The decrease in classified loans compared to at March 31, 2026, was primarily driven by paydowns. Compared to at June 30, 2025, classified loans increased due to loan downgrades.

Annualized net charge-offs were 0.31% of average total loans for the second quarter of 2026, compared to 0.40% for the linked quarter, and 0.43% for the second quarter of 2025. Compared to the linked quarter and prior year second quarter, net charge-offs decreased, driven by a reduction in net charge-offs in leases originated by the North Star Leasing division and indirect consumer loans.

At June 30, 2026, the allowance for credit losses decreased $0.3 million when compared to at March 31, 2026, and increased $3.4 million when compared to at June 30, 2025. The ratio of the allowance for credit losses as a percent of total loans was 1.14% at June 30, 2026, compared to 1.16% at March 31, 2026, and 1.13% at June 30, 2025. The ratio of allowance for credit losses as a percentage of non-performing loans was 190.78% at June 30, 2026, compared to 198.16% at March 31, 2026, and 183.89% at June 30, 2025.

Deposits:

As of June 30, 2026, period-end core deposits decreased $155.1 million compared to at March 31, 2026. The decrease in core deposits was attributable to decreases of $92.4 million retail certificates of deposit and $87.1 million in governmental deposits, driven by seasonality, partially offset by an increase of $37.1 million in money market deposit accounts.

Compared to at December 31, 2025, period-end core deposit balances increased $36.6 million. The increase was primarily driven by increases in money market deposit accounts and non-interest bearing deposits, partially offset by a decrease in retail certificate of deposits.

6

Compared to at June 30, 2025, period-end core deposit balances increased $36.3 million. The decrease in total deposits was primarily driven by increases of $67.9 million in money market deposit accounts, $63.0 million in non-interest bearing deposits, $36.0 million in interest-bearing demand accounts, and $25.6 million in savings accounts, partially offset by a decrease of $129.3 million in retail certificates of deposit.

The total deposit balances attributable to retail deposits and commercial deposits were 78% and 22%, respectively, at June 30, 2026, 77% and 23%, respectively, at March 31, 2026, and 78% and 22%, respectively, at June 30, 2025.

Uninsured deposits were 27%, 28%, and 26% of total deposits at June 30, 2026, at March 31, 2026, and at June 30, 2025, respectively. Uninsured amounts were based on the portion of customer account balances that exceeded the FDIC limit of $250,000. Peoples pledges investment securities against certain governmental deposit accounts, which collateralized $595.7 million, or 30%, $678.1 million, or 32%, and $641.1 million, or 32%, of the uninsured deposit balances at June 30, 2026, at March 31, 2026, and at June 30, 2025, respectively.

Average deposit balances during the second quarter of 2026, increased $38.6 million when compared to the linked quarter, and decreased $94.2 million when compared to the second quarter of 2025. The increase over the linked quarter was driven by increases of $44.8 million in money market deposit accounts, $36.1 million in interest-bearing checking accounts, $35.7 million in governmental deposits, and $26.6 million in non-interest bearing deposit accounts, partially offset by decreases of $63.9 million and $55.3 million in brokered deposits and retail certificates of deposits, respectively. The decrease when compared to the second quarter of 2025 was driven by decreases of $181.7 million in brokered deposits and $80.3 million in retail certificates of deposit, partially offset by increases of $84.8 million, $32.2 million, and $27.8 million in non-interest bearing deposits, money market deposit accounts, and savings accounts, respectively. Total demand deposit accounts comprised 36% of total deposits at June 30, 2026, 35% at March 31, 2026, and 34% at June 30, 2025.

For the first six months of 2026 average deposit balances decreased $105.0 million when compared to the first six months of 2025. The decrease was primarily a result of decreases of $222.2 million in brokered deposits and $23.6 million in retail certificates of deposits, partially offset with increases of $95.2 million, $26.1 million, and $21.9 million in non-interest bearing deposits, savings accounts, and money market deposit accounts, respectively.

Stockholders' Equity:

Total stockholders' equity at June 30, 2026, increased $20.5 million, or 2%, compared to at March 31, 2026. This change was primarily driven by net income of $28.0 million and a decrease of $5.2 million in accumulated other comprehensive loss during the quarter, partially offset by dividends paid of $15.1 million. The decrease in accumulated other comprehensive loss was the result of the sales of available-for-sale investment securities during the period.

Total stockholders' equity at June 30, 2026 increased $29.9 million when compared to at December 31, 2025. This change was driven by net income of $57.0 million, partially offset by dividends paid of $29.8 million.

Total stockholders' equity at June 30, 2026, increased $83.2 million, or 7%, compared to at June 30, 2025, which was due to net income of $118.2 million for the last twelve months and a decrease in other comprehensive loss of $19.4 million, partially offset by dividends paid of $59.0 million.

Use of Non-US GAAP Financial Measures:

This news release contains financial information and performance measures determined by methods other than those in accordance with accounting principles generally accepted in the United States of America ("US GAAP"). Management uses these "non-US GAAP" financial measures in its analysis of Peoples' performance and the efficiency of its operations. Management believes that these non-US GAAP financial measures provide a greater understanding of ongoing operations and enhance comparability of results with prior periods and peers. These disclosures should not be viewed as substitutes for financial measures determined in accordance with US GAAP, nor are they necessarily comparable to non-US GAAP performance measures that may be presented by other companies. Below is a listing of the non-US GAAP financial measures used in this news release:

◦Core non-interest expense is a non-US GAAP financial measure since it excludes the impact of acquisition-related expenses.

◦The efficiency ratio is calculated as total non-interest expense (less amortization of other intangible assets) as a percentage of fully tax-equivalent net interest income plus total non-interest income, excluding net gains and losses. This ratio is a non-US GAAP financial measure since it excludes amortization of other intangible assets and all gains and losses included in earnings, and uses fully tax-equivalent net interest income.

◦The efficiency ratio adjusted for non-core items is calculated as core non-interest expense (less amortization of other intangible assets) as a percentage of fully tax-equivalent net interest income plus total non-interest income, excluding net gains and losses. This ratio is a non-US GAAP financial measure since it excludes the impact of acquisition-related expenses and the amortization of other intangible assets and all gains and losses included in earnings, and uses fully tax-equivalent net interest income.

◦Tangible assets, tangible equity, the tangible equity to tangible assets ratio, and tangible book value per common share are non-US GAAP financial measures since they exclude the impact of goodwill and other intangible assets acquired through acquisitions on both total stockholders' equity and total assets.

◦Total non-interest income, excluding net gains and losses, is a non-US GAAP financial measure since it excludes all gains and losses included in earnings.

◦Pre-provision net revenue is defined as net interest income plus total non-interest income, excluding net gains and losses, minus total non-interest expense. This measure is a non-US GAAP financial measure since it excludes the provision for (recovery of) credit losses and all gains and losses included in net income.

◦Return on average assets adjusted for non-core items is calculated as annualized net income (less the after-tax impact of all gains and losses, and acquisition-related expenses) divided by average assets. This measure is a non-US GAAP financial measure since it excludes the after-tax impact of all gains and losses, and acquisition-related expenses.

◦Return on average tangible equity is calculated as annualized net income (less the after-tax impact of amortization of other intangible assets) divided by average tangible equity. This measure is a non-US GAAP financial measure since it excludes the after-tax impact of amortization of other intangible assets from net income and the impact of average goodwill and other average intangible assets acquired through acquisitions on average stockholders' equity.

A reconciliation of these non-US GAAP financial measures to the most directly comparable US GAAP financial measures is included at the end of this news release under the caption of "Non-US GAAP Financial Measures (Unaudited)."

(19)Peoples' ability to secure confidential information and avoid misappropriation of confidential information in connection with the delivery of products and services through the use of computer systems and telecommunications networks, including those of Peoples' third-party vendors and other service providers, which may prove inadequate, and could adversely affect customer confidence in Peoples and/or result in Peoples incurring a financial loss;

(20)Peoples' ability to anticipate and respond to technological changes, and Peoples' reliance on, and the potential failure of, a number of third-party vendors to perform as expected, including Peoples' primary core banking system provider, which can impact Peoples' ability to respond to customer needs and meet competitive demands;

Peoples filed a registration statement on Form S-4 (Registration No. 333-296361) and other documents regarding the proposed merger with Citizens National Corporation (“Citizens”) with the Securities and Exchange Commission (the “SEC”). The registration statement includes a proxy statement of Citizens that also constitutes a prospectus of Peoples, which has been sent to the shareholders of Citizens seeking their approval of the merger-related proposals. Investors and security holders are urged to read the proxy statement/prospectus and any other relevant documents filed with the SEC in connection with the proposed transaction because they contain or will contain important information about Peoples, Citizens and the proposed transaction.

3 This presentation contains financial information and performance measures determined by methods other than those in accordance with accounting principles generally accepted in the United States of America (“US GAAP”). Management uses these “non-US GAAP” financial measures in its analysis of Peoples’ performance and the efficiency of its operations. Management believes that these non-US GAAP financial measures provide a greater understanding of ongoing operations and enhance comparability of results with prior periods and peers. These disclosures should not be viewed as substitutes for financial measures determined in accordance with US GAAP, nor are they necessarily comparable to non-US GAAP performance measures that may be presented by other companies. A reconciliation of these non-US GAAP financial measures to the most directly comparable US GAAP financial measures is included under the caption “Non-US GAAP Financial Measures (Unaudited)” at the end of the Second Quarter Earnings Release.
