As a result of the acquisition of Piedmont Bancorp, Inc.

Fourth quarter of 2025 compared to the third quarter of 2025

Earnings for the fourth quarter of 2025 were $128.8 million, or $0.91 per diluted share, as compared to earnings of $130.7 million, or $0.92 per diluted share, for the third quarter of 2025.

Net interest income for the fourth quarter of 2025 was a record $287.5 million, an increase of $7.3 million, or 3%, from the third quarter of 2025. Tax-equivalent net interest income, a non-GAAP measure which adjusts for the tax-favored status of income from certain loans and investments, for the fourth quarter of 2025 increased $7.4 million, or 3%, from the third quarter of 2025. The increase in net interest income and tax-equivalent net interest income was driven by a lower average rate paid on deposits and loan growth partially offset by a lower yield on average net loans and loans held for sale and an increase in average interest-bearing deposits. The net interest spread increased 10 basis points to 3.04% for the fourth quarter of 2025 due to a 21 basis point decrease in the average cost of funds partially offset by an 11 basis point decrease in the average yield on earning assets. The cost of average interest-bearing deposits decreased 21 basis points to 2.63% for the fourth quarter of 2025. The yield on average net loans and loans held for sale decreased 8 basis points to 6.18% for the fourth quarter of 2025. Average net loans and loans held for sale increased $390.9 million from the third quarter of 2025 funded by an increase in average interest-bearing deposits of $399.2 million from the third quarter of 2025. The net interest margin was 3.83% and 3.80% for the fourth quarter of 2025 and the third quarter of 2025, respectively.

The provision for credit losses was $6.8 million for the fourth quarter of 2025 as compared to $12.1 million for the third quarter of 2025.

Noninterest income for the fourth quarter of 2025 was $30.9 million, a decrease of $12.3 million, or 28%, from the third quarter of 2025. Net losses on investment securities were $218 thousand for the fourth quarter of 2025 as compared to net gains on investment securities of $10.4 million for the third quarter of 2025. Net losses and gains on investment securities for the fourth quarter of 2025 and third quarter of 2025, respectively, were primarily due to changes in the fair value of equity securities. The remainder of the decrease in noninterest income from the third quarter of 2025 was driven by decreases in several other categories of noninterest income, none of which were significant.

Noninterest expense for the fourth quarter of 2025 was $151.7 million, an increase of $5.0 million, or 3%, from the third quarter of 2025. The expense for the reserve for unfunded loan commitments was $2.4 million for the fourth quarter of 2025 as compared to a net benefit of $3.2 million for the third quarter of 2025. The expense for the reserve for unfunded loan commitments for the fourth quarter of 2025 was primarily due to an increase in the outstanding balance of construction loan commitments. The net benefit in the expense for the reserve for unfunded loan commitments for the third quarter of 2025 was primarily due to a decrease in the modeled loss rate within certain loan portfolios partially offset by an increase in the outstanding balance of loan commitments from the prior quarter-end. Additionally, a $1.7 million decrease in employee benefits was largely offset by an increase in other noninterest expense of $1.5 million. The fluctuations in these noninterest expense categories were driven by certain general operating expenses, none of which were individually significant.

For the fourth quarter of 2025, income tax expense was $31.1 million, a decrease of $2.7 million from the third quarter of 2025. This decrease in income tax expense was primarily due to the impact of a lower effective tax rate and lower earnings. United’s effective tax rate was 19.4% and 20.5% for the fourth quarter of 2025 and third quarter of 2025, respectively. The lower effective tax rate was primarily due to the impact of provision to return adjustments in the fourth quarter of 2025.

Fourth quarter of 2025 compared to the fourth quarter of 2024

Earnings for the fourth quarter of 2025 were $128.8 million, or $0.91 per diluted share, as compared to earnings of $94.4 million, or $0.69 per diluted share, for the fourth quarter of 2024.

Net interest income for the fourth quarter of 2025 increased $54.8 million, or 24%, from the fourth quarter of 2024. Tax-equivalent net interest income increased $54.9 million, or 24%, from the fourth quarter of 2024. The increase in net interest income and tax-equivalent net interest income was primarily due to an increase in average earning assets, a lower average rate paid on deposits, and an increase in acquired loan accretion income. These increases to net interest income and tax-equivalent net interest income were partially offset by an increase in average interest-bearing deposits. Average earning assets increased $3.3 billion, or 12%, from the fourth quarter of 2024, driven by increases in average net loans and loans held for sale of $3.0 billion and average short-term investments of $497.3 million, partially offset by a decrease in average investment securities of $198.4 million. The increase in average loans from the fourth quarter of 2024 was driven by the Piedmont acquisition and organic loan growth. The cost of average interest-bearing deposits decreased 39 basis points from the fourth quarter of 2024. Acquired loan accretion income was $8.5 million for the fourth quarter of 2025 as compared to $2.0 million for the fourth quarter of 2024. Average interest-bearing deposits increased $2.5 billion, or 14%, from the fourth quarter of 2024. The net interest margin of 3.83% for the fourth quarter of 2025 was an increase of 34 basis points from the net interest margin of 3.49% for the fourth quarter of 2024.

The provision for credit losses was $6.8 million for the fourth quarter of 2025 as compared to $6.7 million for the fourth quarter of 2024.

Noninterest income for the fourth quarter of 2025 increased $1.6 million, or 6%, from the fourth quarter of 2024. The increase in noninterest income was primarily due to an increase in fees from brokerage services of $980 thousand driven by higher volume.

Noninterest expense for the fourth quarter of 2025 increased $17.5 million, or 13%, from the fourth quarter of 2024. Employee compensation increased $5.8 million from the fourth quarter of 2024 primarily due to higher employee headcount from the acquisition and higher employee incentives. The expense for the reserve for unfunded loan commitments was $2.4 million for the fourth quarter of 2025 as compared to a net benefit of $3.1 million for the fourth quarter of 2024. Other noninterest expense increased $2.3 million from the fourth quarter of 2024 due to a $2.4 million increase in tax credit amortization and higher amounts of certain general operating expenses partially offset by a decline of $1.3 million in merger-related expenses. Additionally, increases in equipment expense of $1.8 million, amortization of intangibles of $1.4 million, and net occupancy of $1.1 million were mainly attributable to the acquisition.

For the fourth quarter of 2025, income tax expense was $31.1 million as compared to $26.7 million for the fourth quarter of 2024. This increase of $4.4 million in income tax expense was driven by higher earnings partially offset by a lower effective tax rate. United’s effective tax rate was 19.4% and 22.0% for the fourth quarter of 2025 and fourth quarter of 2024, respectively. The effective tax rates for the fourth quarters of 2025 and 2024 reflect the impact of provision to return adjustments during each period.

Year of 2025 compared to the year of 2024

Earnings for the year of 2025 were $464.6 million, or $3.27 per diluted share, as compared to earnings of $373.0 million, or $2.75 per diluted share, for the year of 2024.

Net interest income for the year of 2025 increased $191.1 million, or 21%, from the year of 2024. Tax-equivalent net interest income for the year of 2025 increased $190.9 million, or 21%, from the year of 2024. The increase in net interest income and tax-equivalent net interest income was primarily due to an increase in average earning assets, a lower average rate paid on deposits, an increase in acquired loan accretion income, and a decrease in average long-term borrowings. These increases to net interest income and tax-equivalent net interest income were partially offset by an increase in average interest-bearing deposits. Average earning assets increased $3.0 billion, or 11%, from the year of 2024, driven by increases in average net loans and loans held for sale of $2.5 billion and average short-term investments of $896.6 million, partially offset by a decrease in average investment securities of $385.9 million. The cost of average interest-bearing deposits decreased 35 basis points from the year of 2024. Acquired loan accretion income was $33.7 million for the year of 2025 as compared to $9.3 million for the year of 2024. Average long-term borrowings decreased $472.6 million, or 46%, from the year of 2024. Average interest-bearing deposits increased $2.7 billion, or 16%, from the year of 2024. The net interest margin of 3.78% for the year of 2025 was an increase of 29 basis points from the net interest margin of 3.49% for the year of 2024.

The provision for credit losses was $53.9 million for the year of 2025, which included $18.7 million of provision recorded on purchased non-credit deteriorated (“non-PCD”) loans from Piedmont. The provision for credit losses was $25.2 million for the year of 2024.

Noninterest income for the year of 2025 was $135.2 million, an increase of $11.5 million, or 9%, from the year of 2024. The increase in noninterest income was driven by net gains on investment securities for the year of 2025 of $11.2 million as compared to net losses on investment securities for the year of 2024 of $7.7 million, a $2.5 million increase in fees from brokerage services, a $2.0 million increase in income from bank-owned life insurance (“BOLI”), and a $1.8 million increase in fees from deposit services. Partially offsetting these increases in noninterest income were a $9.0 million decrease in mortgage loan servicing income and a $6.5 million decrease in income from mortgage banking activities. Net gains on investment securities of $11.2 million for the year of 2025 were primarily due to net unrealized fair value gains on equity securities. Net losses on investment securities of $7.7 million for the year of 2024 included $16.0 million in losses on sales of available for sale (“AFS”) investment securities partially offset by a $6.9 million gain on the VISA share exchange. The increase in BOLI income was primarily due to the impact of higher market values of underlying investments and policies added from the acquisition. Increases in fees from brokerage services and in fees from deposit services were primarily due to higher volume. The decrease in mortgage loan servicing income was due to sales of mortgage servicing rights (“MSRs”) in 2024. The decrease in income from mortgage banking activities was primarily due to lower mortgage production in 2025.

Noninterest expense for the year of 2025 was $600.1 million, which included $12.7 million in merger-related expenses, while noninterest expense was $545.0 million for the year of 2024, which included $2.9 million in merger-related expenses. Employee compensation increased $17.4 million for the year of 2025 primarily due to $1.5 million in merger-related expenses, higher employee headcount mainly from the acquisition, and higher employee incentives partially offset by lower commissions driven by a decrease in mortgage production. Other noninterest expense increased $14.2 million, driven by $7.0 million in merger-related expenses recognized during the year of 2025 as compared to $2.9 million for the year of 2024, a $2.6 million increase in tax credit amortization, and higher amounts of certain other general operating costs. The expense for the reserve for unfunded loan commitments for the year of 2025 increased $10.0 million from the year of 2024 due in large part to $4.1 million in merger-related expenses from the Piedmont acquisition. Additionally, increases in several other categories of noninterest expense mainly from the acquisition were partially offset by a $2.7 million decrease in Federal Deposit Insurance Corporation (“FDIC”) insurance expense primarily related to the special assessment and a $2.4 million decrease in mortgage loan servicing expense due to the aforementioned sales in 2024.

For the year of 2025, income tax expense was $118.8 million as compared to $91.6 million for the year of 2024. The increase of $27.2 million was primarily due to higher earnings and a higher effective tax rate. United’s effective tax rate was 20.4% for the year of 2025 and 19.7% for the year of 2024. The effective tax rates for the years of 2025 and 2024 reflect the impact of provision to return adjustments during each period. Additionally, the effective tax rate for the year of 2024 reflects the impact of discrete tax benefits recognized in the second quarter of 2024.

The decrease in the allowance for loan and lease losses from September 30, 2025, to December 31, 2025, was driven by improved collateral valuations of certain individually assessed loans and resolutions of certain individually assessed loans.

During the first quarter of 2025, United recorded an allowance for loan & lease losses on acquired Piedmont non-PCD loans of $18.7 million and on acquired Piedmont purchased credit deteriorated (“PCD”) loans of $17.5 million.

Cautionary Statements

The Company is required under generally accepted accounting principles to evaluate subsequent events through the filing of its December 31, 2025 consolidated financial statements on Form 10-K. As a result, the Company will continue to evaluate the impact of any subsequent events on critical accounting assumptions and estimates made as of December 31, 2025 and will adjust amounts preliminarily reported, if necessary.

Use of non-GAAP Financial Measures

This press release contains certain financial measures that are not recognized under U.S. generally accepted accounting principles (“GAAP”). Generally, United has presented these “non-GAAP” financial measures because it believes that these measures provide meaningful additional information to assist in the evaluation of United’s results of operations or financial position. Presentation of these non-GAAP financial measures is consistent with how United’s management evaluates its performance internally and these non-GAAP financial measures are frequently used by securities analysts, investors, and other interested parties in the evaluation of companies in the banking industry.

Specifically, this press release contains certain references to financial measures identified as tax-equivalent (FTE) net interest income, average tangible equity, return on average tangible equity, and tangible book value per share. Management believes these non-GAAP financial measures to be helpful in understanding United’s results of operations or financial position.

Net interest income is presented in this press release on a tax-equivalent basis. The tax-equivalent basis adjusts for the tax-favored status of income from certain loans and investments. Although this is a non-GAAP measure, United’s management believes this measure is more widely used within the financial services industry and provides better comparability of net interest income arising from taxable and tax-exempt sources. United uses this measure to monitor net interest income performance and to manage its balance sheet composition. The tax-equivalent adjustment combines amounts of interest income on federally nontaxable loans and investment securities using the statutory federal income tax rate of 21%.

Tangible equity is calculated as GAAP total shareholders’ equity minus total intangible assets. Tangible equity can thus be considered the most conservative valuation of the company. Tangible equity is also presented on a per common share basis and considering net income, a return on average tangible equity. Management provides these amounts to facilitate the understanding of as well as to assess the quality and composition of United’s capital structure. By removing the effect of intangible assets that result from merger and acquisition activity, the “permanent” items of equity are presented. These measures, along with others, are used by management to analyze capital adequacy and performance.

Where non-GAAP financial measures are used, the comparable GAAP financial measure, as well as reconciliation to that comparable GAAP financial measure can be found in the attached financial information tables to this press release. Investors should recognize that United’s presentation of these non-GAAP financial measures might not be comparable to similarly titled measures at other companies. These non-GAAP financial measures should not be considered a substitute for GAAP basis measures and United strongly encourages a review of its condensed consolidated financial statements in their entirety.
