MARIETTA, Ohio - Peoples Bancorp Inc. ("Peoples") (NASDAQ: PEBO) today announced results for the quarter ended June 30, 2024. Net income totaled $29.0 million for the second quarter of 2024, representing earnings per diluted common share of $0.82. In comparison, Peoples reported net income of $29.6 million, representing earnings per diluted common share of $0.84, for the first quarter of 2024 and net income of $21.1 million, representing earnings per diluted common share of $0.64, for the second quarter of 2023.

"We are pleased with our results for the quarter, in particular our loan growth and continued stable credit metrics. Additionally, we are very honored to be recognized by Newsweek for being awarded one of America's Best Regional Banks and one of America's Greatest Workplaces, one of only five banks being recognized for both awards," said Tyler Wilcox, President and Chief Executive Officer. "We continue to focus on creating a top tier workplace while producing solid and consistent performance."

•Net interest income for the second quarter of 2024 was relatively consistent when compared to the linked quarter, with higher interest income offset by higher funding costs.

◦Net interest margin decreased to 4.18% for the second quarter of 2024, compared to 4.26% for the linked quarter driven by lower accretion income.

•Peoples recorded a provision for credit losses of $5.7 million for the second quarter of 2024, compared to a provision for credit losses of $6.1 million for the first quarter of 2024.

◦The provision for credit losses negatively impacted earnings per diluted common share by $0.13 for the second quarter of 2024 and $0.14 for the first quarter of 2024.

•Total non-interest income, excluding net gains and losses, decreased $1.6 million, or 6%, for the second quarter of 2024 compared to the linked quarter.

◦The decrease was primarily driven by lower insurance income due to annual contingency income recognized in the first quarter of each year.

•Total non-interest expense for the second quarter of 2024 increased $0.3 million compared to the linked quarter.

◦The efficiency ratio for the second quarter of 2024 was 59.2%, compared to 58.1% for the linked quarter.

•Period-end total loan and lease balances at June 30, 2024 increased $122.5 million, or 8% annualized, compared to at March 31, 2024.

◦The increase was driven by growth in (i) premium finance loans, (ii) commercial and industrial loans, (iii) constructions loans, and (iv) consumer indirect loans, partially offset by a decrease in other commercial real estate loans.

•Asset quality metrics remained stable during the second quarter of 2024.

◦Delinquency trends improved compared to March 31, 2024.

◦Criticized and classified loans both decreased and were driven by the paydowns of previously downgraded commercial and industrial relationships.

◦Annualized net charge-offs were 0.27% of average total loans, representing a return to pre-pandemic levels.

•Period-end total deposit balances at June 30, 2024 decreased $28.8 million compared to at March 31, 2024

◦Excluding a decrease in brokered certificates of deposit of $70.8 million, core deposits were up $42.0 million compared to the linked quarter, driven by an increase in retail certificates of deposits and higher money market deposit accounts.

◦Total loan balances were 87% of total deposit balances at June 30, 2024, compared to 85% at March 31, 2024.

As of the close of business on April 30, 2023, Peoples completed its previously announced merger with Limestone Bancorp, Inc. (“Limestone”), a bank holding company headquartered in Louisville, Kentucky, and the parent company of Limestone Bank, pursuant to a definitive Agreement and Plan of Merger (the “Merger Agreement”) dated October 24, 2022. Under the terms of the Merger Agreement, Limestone merged with and into Peoples, and immediately thereafter Limestone Bank merged with and into Peoples’ wholly-owned subsidiary, Peoples Bank (collectively, the "Limestone Merger"), in a transaction valued at $177.9 million. Peoples recorded acquisition-related expenses, primarily related to the Limestone Merger, which included $(0.1) million and $10.7 million in other non-interest expense for the three months ended March 31, 2024, and three months ended June 30, 2023, respectively. There was no such expense for the three months ended June 30, 2024. For the six months ended June 30, 2024, Peoples recorded acquisition expenses of $(0.1) million compared to $11.3 million for the six months ended June 30, 2023.

Net interest income was $86.6 million for the second quarter of 2024 and was relatively flat when compared to the linked quarter. Net interest margin was 4.18% for the second quarter of 2024, compared to 4.26% for the linked quarter. The decrease in net interest margin was primarily driven by a decrease in accretion income, net of amortization, from acquisitions and higher borrowing costs, which offset higher earning asset yields.

Net interest income for the second quarter of 2024 increased $1.8 million, or 2%, compared to the second quarter of 2023. The increase in net interest income compared to the second quarter of 2023 was driven by increases in market interest rates, the Limestone Merger, and organic growth. Net interest margin decreased 36 basis points when compared to the second quarter of 2023, driven primarily by an increase in interest expense on deposits.

Accretion income, net of amortization expense, from acquisitions was $5.8 million for the second quarter of 2024, $6.5 million for the first quarter of 2024 and $4.5 million for the second quarter of 2023, which added 29 basis points, 32 basis points and 24 basis points, respectively, to net interest margin. The decrease in accretion income for the second quarter of 2024 when compared to the linked quarter was primarily driven by lower pay-offs. The increase in accretion income for the current quarter compared to the second quarter of 2023 was a result of the accretion from the Limestone Merger.

For the first six months of 2024, net interest income increased $15.5 million, or 10%, compared to the first six months of 2023, while net interest margin decreased 31 basis points to 4.22%. The increase in net interest income was driven by increases in market interest rates and an additional four months of income from the Limestone Merger. The decrease in net interest margin for the first six months of 2024 compared to the first six months of 2023 was primarily driven by higher borrowing costs, which offset higher earning asset yields.

Accretion income, net of amortization expense, from acquisitions was $12.3 million for the six months ended June 30, 2024, compared to $6.5 million for the six months ended June 30, 2023, which added 30 and 18 basis points, respectively, to net interest margin. The increase in accretion income for the first six months of 2024 compared to the same period in 2023 was due to more accretion in 2024 from the Limestone Merger.

The provision for credit losses was $5.7 million for the second quarter of 2024, compared to $6.1 million for the linked quarter and $8.0 million for the second quarter of 2023. The provision for credit losses for the second quarter of 2024 was a result of (i) higher net charge-offs, (ii) an increase of reserves on individually analyzed loans and leases, and (iii) loan growth. The provision for credit losses for the first quarter of 2024 was driven by (i) a deterioration in macro-economic conditions used within the current expected credit loss ("CECL") model, (ii) an increase of reserves on individually analyzed loans and leases and (iii) loan growth. The decrease in the provision for credit losses for the second quarter of 2024 compared to the second quarter of 2023, was largely attributable to the provision for loans acquired in the Limestone Merger recorded in the second quarter of 2023, as well as a reduction in the reserves for individually analyzed loans and leases, offset by loan growth, an increase in net charges-offs and economic forecast deterioration.

The provision for credit losses during the first six months of 2024 was $11.8 million, compared to a provision for credit losses of $9.8 million for the first six months of 2023. The provision for credit losses during the first six months of 2024 was mainly a result of (i) higher net charge-offs, (ii) an increase in reserves on individually analyzed loans and leases and (iii) loan growth. The provision for credit losses during the first six months of 2023 was driven by (i) the addition of the provision for the non-purchased credit deteriorated loans acquired in the Limestone Merger, (ii) loan growth and (iii)

economic forecast deterioration, partially offset by a reduction in the reserves for individually analyzed loans and leases and the use of updated loss drivers.

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 $0.13 for the second quarter of 2024, $0.14 for the first quarter of 2024, and $0.19 for the second quarter of 2023. For the first six months of 2024, the provision negatively impacted earnings per diluted common share by $0.27, compared to $0.25 for the first six months of 2023.

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 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 2024 was $0.8 million, compared to a net loss of $0.3 million for the linked quarter, and a net loss of $1.8 million for the second quarter of 2023. The net loss for the second quarter of 2024 was driven primarily by $0.4 million of net losses on repossessed assets. The net loss for the linked quarter was primarily due to $0.3 million of net losses on repossessed assets. The second quarter of 2023 net loss was primarily driven by a $1.6 million write-down of an other real estate owned ("OREO") property.

The net loss realized during the first six months of 2024 was $1.1 million, compared to a net loss realized of $4.0 million for the first six months of 2023. The net loss for the first six months of 2024 was primarily driven by the $0.7 million of net losses on repossessed assets mentioned above. The net loss recognized in the first six months of 2023 was primarily driven by a $2.0 million pre-tax net loss on the sale of available-for-sale investment securities and the $1.6 million write-down of an OREO property mentioned above.

Total non-interest income, excluding net gains and losses, for the second quarter of 2024 decreased $1.6 million compared to the linked quarter. The decrease in non-interest income, excluding net gains and losses, was primarily impacted by a decrease of $2.4 million in insurance income due to seasonal performance-based commissions being paid in the first quarter of each year. Partially offsetting the decrease was an increase of $0.4 million in each of electronic banking income and trust and investment income, respectively. Total non-interest income, excluding net gains and losses, for the second quarter of 2024 was 22% of total revenue (defined as net interest income plus total non-interest income excluding net gains and losses) compared to 23% for the first quarter of 2023.

Compared to the second quarter of 2023, total non-interest income, excluding net gains and losses, increased $1.6 million, primarily due to a $1.1 million increase in other non-interest income, driven by operating lease income, and a $0.6 million increase in trust and investment income, partially offset by a $0.6 million decrease in lease income. The increases for the second quarter of 2024, when compared to the second quarter of 2023, were primarily due to the additional customers brought in from the Limestone Merger and increases of assets under administration and management.

For the first six months of 2024, total non-interest income, excluding gains and losses, increased $6.5 million, or 15%, compared to the first six months of 2023. The increase was driven by (i) a $2.1 million increase in other non-interest income, driven by operating lease income, (ii) a $1.2 million increase in insurance income, (iii) a $1.1 million increase in trust and investment income, (iv) a $1.0 million increase in bank owned life insurance income, (v) a $0.9 million increase in deposit account service charge income, and (vi) a $0.6 million increase in electronic banking income, offset by a $0.4 million decrease in lease income. The increases for the first six months of 2024, when compared to the first six months of 2023, were primarily due to the additional customers brought in from the Limestone Merger, increases of assets under administration and management, higher contingency income, and market increases for premiums.

Total non-interest expense increased $0.3 million for the second quarter of 2024, compared to the linked quarter. The increase in total non-interest expense was primarily due to increases of $2.2 million in other non-interest expense driven by a one-time $1.3 million true-up of corporate expenses and $1.0 million in data processing and software expense driven by higher expenses attributable to recent technology projects, partially offset by a decrease of $2.3 million in salaries and employee benefit costs. The decrease in salaries and employee benefits costs was due to annual expenses that occur in the first quarter of each year including annual merit increases, stock-based compensation expenses attributable to retirement-eligible employees and health savings account ("HSA") contributions.

Compared to the second quarter of 2023, total non-interest expense decreased $1.9 million, or 3%. Excluding acquisition-related expenses, non-interest expenses increased $8.8 million, or 15%, primarily due to increases of $3.7 million in salaries and employee benefits costs due to additional employees added in the Limestone Merger, and $2.0 million in data processing and software expense due to the recent growth, including through acquisitions.

For the six months of 2024, total non-interest expense increased $10.1 million, or 8%, compared to the first six months of 2023. Excluding acquisition-related expenses, non-interest expenses increased $21.5 million, or 19%, primarily due to increases of $10.5 million in salaries and employee benefits costs due to additional employees added in the Limestone Merger, and $3.2 million and $2.1 million in data processing and software expense and in net occupancy and equipment expense, respectively, due to recent growth, included through acquisitions.

The table below summarizes the amount of acquisition-related expenses for each line item that is a component of non-interest expense. Acquisition-related expenses are considered a non-core non-interest expense by Peoples. This information is used by Peoples to provide information useful to investors in understanding Peoples' operating performance and trends.

The efficiency ratio for the second quarter of 2024 was 59.2%, compared to 58.1% for the linked quarter and 62.7% for the second quarter of 2023. The efficiency ratio improved compared to the prior year quarter due to the decrease in acquisition-related expenses. The efficiency ratio, adjusted for non-core items, was 59.2% for the second quarter of 2024, compared to 58.1% for the linked quarter, and 53.3% for the second quarter of 2023. The efficiency ratio and the adjusted for non-core items efficiency ratio increased compared to the linked quarter increased mainly as the result of a reduction in non-interest income.

The efficiency ratio for the first six months of 2024 was 58.6%, compared to 60.4% for the first six months of 2023. The efficiency ratio improved compared to the prior year first six months due to the decrease in acquisition-related expenses. The efficiency ratio, adjusted for non-core items, was 58.7% for the first six months of 2024, compared to 55.2% for the first six months of 2023. Peoples continues to focus on controlling expenses, while recognizing necessary costs in order to continue growing the business.

Peoples recorded income tax expense of $6.9 million with an effective tax rate of 19.1% for the second quarter of 2024, compared to income tax expense of $8.3 million with an effective tax rate of 21.8% for the linked quarter and income tax expense of $6.2 million with an effective tax rate of 22.6% for the second quarter of 2023. The decrease in income tax expense when compared to the prior quarter was driven by a $1.1 million one-time benefit related to a prior year amended return. The increase in income tax expense when compared to the second quarter of 2023 was primarily due to higher pre-tax income. Peoples recorded income tax expense of $15.1 million with an effective tax rate of 20.5% for the first six months of 2024 and $13.2 million with an effective tax rate of 21.7% in the first six months of 2023. The increase was driven by higher pre-tax income.

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, 2024 increased $2.7 million when compared to at March 31, 2024, increased $70.8 million when compared to at December 31, 2023, and decreased $14.3 million when compared to at June 30, 2023. The decrease in the balance when compared to at June 30, 2023, was driven by principal payment reductions. The balances of unrealized losses, net of tax, on available-for-sale investment securities recognized within accumulated other comprehensive loss were $112.7 million, $111.8 million, and $121.5 million at June 30, 2024, at March 31, 2024, and at June 30, 2023, respectively.

The held-to-maturity investment securities balance at June 30, 2024 decreased $22.5 million and increased $18.3 million and $28.1 million when compared to at March 31, 2024, at December 31, 2023 and at June 30, 2023, respectively. The decrease when compared to the linked quarter was driven by principal payments. The increase when compared to June 30, 2023 was primarily driven by higher yielding, longer duration securities booked as held-to-maturity. The balances of net unrealized losses on held-to-maturity investment securities were $79.4 million, $77.4 million, and $81.1 million at June 30, 2024, at March 31, 2024, and at June 30, 2023, respectively.

The effective duration of the investment portfolio as of June 30, 2024 was estimated to be 5.26 years. The duration of Peoples’ investments is managed as part of its 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 one 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, 2024, Peoples had liquid and liquefiable assets totaling $607.0 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, 2024, Peoples had a borrowing capacity of $727.3 million available through the Federal Home Loan Bank (“FHLB”), the Federal Reserve Bank ("FRB"), and federal funds. Additionally at June 30, 2024, Peoples had other contingent sources of liquidity totaling $2.7 billion. Cash and cash equivalents decreased $190.9 million when compared to December 31, 2023 due to an improvement in other inputs in our aforementioned liquidity metrics, specifically unencumbered securities, driven by the migration of deposit balances to insured cash sweep accounts ("ICS"), freeing up investment securities previously held as collateral against those balances, and requiring less cash to be held on the balance sheet.

The period-end total loan and lease balances at June 30, 2024 increased $122.5 million, or 8% annualized, compared to at March 31, 2024. The increase in the period-end total loan and lease balances was primarily driven by increases of (i) $54.4 million in premium finance loans, (ii) $43.4 million in commercial and industrial loans, (iii) $25.9 million in construction loans, (iv) $24.8 million in indirect consumer loans, partially offset by a reduction of $47.8 million in other commercial real estate loans.

The period-end total loan and lease balances at June 30, 2024 increased $166.2 million compared to at December 31, 2023, primarily driven by growth of $90.2 million, $73.1 million, and $18.9 million in premium finance loans, commercial and industrial loans, and home equity lines of credit, respectively, partially offset by a decrease of $23.4 million in construction loans.

The period-end total loan and lease balances at June 30, 2024 increased $350.8 million compared to at June 30, 2023, primarily driven by organic growth in our premium finance, other commercial real estate, commercial and industrial, and lease portfolios of $130.1 million, $124.5 million, $97.8 million, and $52.9, respectively.

Quarterly average total loan balances increased $73.5 million compared to the linked quarter. The increase in average total loan balances when compared to the linked quarter was primarily the result of growth of (i) $50.1 million in premium finance loans, (ii) $27.1 million in commercial and industrial loans,and (iii) $9.9 million in leases, partially offset by reductions of $10.5 million in construction loans, $5.4 million in residential real estate loans, and $5.0 million in consumer direct loans.

Compared to the second quarter of 2023, quarterly average loan balances in the current quarter increased $0.7 billion, or 12%. The increase was driven by loans acquired in the Limestone Merger, and to a lesser extent, organic growth in other commercial real estate loans, commercial and industrial loans, premium finance loans, and leases.

Overall, asset quality remained relatively stable through the second quarter of 2024. Delinquency trends remained stable as loans considered current comprised 98.8%, 98.7%, and 99.0% of the loan portfolio at June 30, 2024, at March 31, 2024, and and at June 30, 2023, respectively. Total nonperforming assets at June 30, 2024 increased $2.4 million, or 5%, compared to at March 31, 2024, and increased $6.8 million, or 16%, compared to at June 30, 2023. The increase in nonperforming assets compared to the linked quarter was primarily due to an increase in the balance of nonaccrual small-ticket leases, produced by our North Star Leasing business, and other commercial real estate loans. The increase in nonperforming assets compared to at June 30, 2023, was impacted by the increase of small-ticket nonaccrual leases and an increase in loans past due and accruing. Nonperforming assets as a percent of total loans and OREO was 0.77% at June 30, 2024, compared to 0.74% at March 31, 2024, and 0.70% at June 30, 2023.

Criticized loans, which are those categorized as special mention, substandard or doubtful, decreased $16.6 million, or 6%, compared to at March 31, 2024, increased $4.7 million, or 2%, compared to at December 31, 2023, and increased $20.1 million, or 9%, compared to at June 30, 2023. As a percent of total loans, criticized loans were 3.79% at June 30, 2024, compared to 4.14% at March 31, 2024, 3.82% at December 31, 2023, and 3.68% at June 30, 2023. The decrease in the amount of criticized loans compared to at March 31, 2024 and at December 31, 2023 was primarily driven by paydowns on previously downgraded loans. Compared to June 30, 2023, the increase in the amount of criticized loans was primarily driven by loan downgrades.

Classified loans, which are those categorized as substandard or doubtful, decreased $27.3 million, or 19%, compared to at March 31, 2024, increased $0.2 million compared to at December 31, 2023, and increased $9.2 million, or 8%, compared to at June 30, 2023. As a percent of total loans, classified loans were 1.90% at June 30, 2024, compared to 2.38% at March 31, 2024, 1.95% at December 31, 2023, and 1.86% at June 30, 2023. The decrease in classified loans compared to at March 31, 2024 was driven by paydowns and two upgrades in the commercial portfolio. The increase in classified loans when compared to at June 30, 2023, was primarily driven by loan downgrades.

Annualized net charge-offs were 0.27% of average total loans for the second quarter of 2024, compared to 0.22% for the linked quarter, and 0.09% for the second quarter of 2023. The increase relative to the linked quarter was driven by an increase in charge-offs on small-ticket leases partially offset by decreases in net charge-offs on commercial and industrial loans and other commercial real estate loans. The increase in net charge-offs during the second quarter of 2024 versus the prior year second quarter was primarily attributable to an increase in charge-offs on (i) small-tickets leases, (ii) indirect consumer loans, (iii) commercial and industrial loans, and (iv) other commercial real estate loans.

At June 30, 2024, the allowance for credit losses increased $1.4 million when compared to at March 31, 2024, increased $4.2 million when compared to at December 31, 2023, and increased $5.0 million when compared to at June 30, 2023. The increase in the allowance for credit losses at June 30, 2024 when compared to at March 31, 2024 and at December 31, 2023 was primarily due to an increase on reserves for individually analyzed loans and leases. The increase in the allowance balance at June 30, 2024 when compared to June 30, 2023 was driven by loan growth and a deterioration in macro-economic conditions used within the CECL model, partially offset by a release of reserves on individually analyzed loans and leases. The ratio of the allowance for credit losses as a percent of total loans was 1.05% at June 30, 2024, compared to 1.05% at March 31, 2024, and 1.02% at June 30, 2023.

As of June 30, 2024, period-end total deposits decreased $28.8 million compared to at March 31, 2024. The decrease was primarily driven by decreases of (i) $70.8 million in brokered certificates of deposit, (ii) $58.8 million in governmental deposit accounts, and (iii) $24.2 million in interest-bearing demand deposit accounts, partially offset by an increase of $132.5 million in retail certificates of deposit. The increase in retail certificates of deposits was due to current specials being offered, while the decrease in governmental deposit accounts was due to the seasonality of those balances, which are typically higher in the first quarter. Excluding a decrease in brokered certificates of deposit of $70.8 million, deposits were up $42.0 million compared to the linked quarter, driven by the aforementioned increase in retail certificates of deposits and higher money market deposit accounts.

Compared to December 31, 2023, period-end total deposits increased $145.5 million, or 2%. The increase was primarily driven by increases of $369.5 million in retail certificates of deposit and $93.7 million in money market deposit accounts, partially offset by decreases of $162.8 million in brokered certificates of deposits, $95.0 million in non-interest bearing deposits and $60.8 million in interest bearing demand accounts.

Compared to June 30, 2023, period-end deposit balances increased $337.9 million, or 5%. The increase was primarily driven by increases of $862.1 million in retail certificates of deposit, $150.5 million in money market deposit accounts, and $60.7 million in governmental deposit accounts, offset by decreases of $236.1 million, $209.9 million, $147.3 million, and $142.1 million in savings accounts, non-interest bearing deposits, brokered certificates of deposit, and interest-bearing demand deposit accounts, respectively. The increase in retail certificates of deposits was driven by current promotions being offered.

The percentages of retail deposit balances and commercial deposit balances of the total deposit balance at June 30, 2024 were 78% and 22%, respectively, compared to 76% and 24%, respectively, at March 31, 2024, and 78% and 22%, respectively, at June 30, 2023.

Uninsured deposits were 30%, 32%, and 32% of total deposits at June 30, 2024, at March 31, 2024, and at June 30, 2023, respectively. Uninsured amounts are estimated 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 $748.3 million, or 38%, $865.6 million, or 42%, and $749.9 million, or 38% of the uninsured deposit balances at June 30, 2024, at March 31, 2024, and at June 30, 2023, respectively.

Average deposit balances during the second quarter of 2024 increased $120.2 million when compared to the linked quarter, and increased $0.7 billion, or 11%, when compared to the second quarter of 2023. The increase in average deposit balances compared to the linked quarter was driven by increases of $160.8 million in retail certificates of deposits, $65.6 million in money market deposit accounts, and $32.0 million in governmental deposits, partially offset by decreases of $86.7 million in brokered certificates of deposits and $24.9 million in non-interest bearing deposits. Total demand deposit accounts comprised 35%, 35% and 42% of total deposits at June 30, 2024, at March 31, 2024 and at June 30, 2023, respectively.

Total stockholders' equity at June 30, 2024 increased $15.8 million, or 1%, compared to at March 31, 2024. This change was primarily driven by net income of $29.0 million during the quarter, partially offset by dividends paid of $14.2 million. The increase in accumulated other comprehensive loss was the result of the changes in the market value of available-for-sale investment securities during the period.

Total stockholders' equity at June 30, 2024 increased $24.3 million, or 2%, compared to at December 31, 2023, which was due to net income of $58.6 million in the first six months of 2024, partially offset by dividends paid of $27.9 million and an increase of $8.6 million in accumulated other comprehensive loss.

Total stockholders' equity at June 30, 2024 increased $78.9 million, or 8%, compared to at June 30, 2023, which was due to net income of $124.3 million in the last twelve months and a decrease in other comprehensive loss of $8.7 million, partially offset by dividends paid of $55.9 million.

Compared to at March 31, 2024, and at June 31, 2023, these ratios improved due to net income during the second quarter of 2024, partially offset by dividends paid.

At June 30, 2024, book value per common share and tangible book value per common share, which excludes goodwill and other intangible assets, were $30.36 and $18.91, respectively, compared to $29.93 and $18.39, respectively, at March 31, 2024, and $28.24 and $16.56, respectively, at June 30, 2023.

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 and COVID-19 employee retention credit.

◦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, COVID-19 employee retention credit, 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, acquisition-related expenses, and COVID-19 employee retention credit 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.
