NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

UNITED BANKSHARES, INC. AND SUBSIDIARIES

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying unaudited consolidated interim financial statements of United Bankshares, Inc. and Subsidiaries (“United” or “the Company”) have been prepared in accordance with accounting principles for interim financial information generally accepted in the United States (“GAAP”) and with the instructions for Form 10-Q and Article 10 of Regulation S-X. Accordingly, the financial statements do not contain all of the information and footnotes required by accounting principles generally accepted in the United States. In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. The financial statements presented as of March 31, 2024 and 2023 and for the three-month periods then ended have not been audited. The consolidated balance sheet as of December 31, 2023 has been extracted from the audited financial statements included in United’s 2023 Annual Report to Shareholders. The Notes to Consolidated Financial Statements appearing in United’s 2023 Annual Report on Form 10-K, which includes descriptions of significant accounting policies, should be read in conjunction with these interim financial statements. In the opinion of management, any adjustments necessary for a fair presentation of financial position and results of operations for the interim periods have been made. Such adjustments are of a normal and recurring nature.

The accompanying consolidated interim financial statements include the accounts of United and its wholly owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in the consolidated financial statements. Information is presented in these notes to the unaudited consolidated interim financial statements with dollars expressed in thousands, except per share or unless otherwise noted.

Operating and Reporting Segments

As of March 31, 2024, United’s business activities are confined to one operating segment, United Bank, and one reportable segment, community banking. As a community banking entity, United, through United Bank, offers a full range of products and services through various delivery channels. Included among the banking products and services offered are the acceptance of deposits in checking, savings, time and money market accounts; the making and servicing of personal, credit card, commercial, and floor plan loans; and the making of construction and real estate loans as well as the origination and sale of residential mortgages in the secondary market. Also offered are trust and brokerage services, safe deposit boxes, and wire transfers. United’s chief operating decision maker regularly reviews the operating results of United Bank in order to assess performance and make decisions about resource allocation. Previously, United had three operating segments: United Bank, George Mason Mortgage, LLC (“George Mason”) and Crescent Mortgage Company (“Crescent”), and two reporting segments: community banking and mortgage banking. However, during the first quarter of 2024, United consolidated the mortgage origination and sales business of George Mason and Crescent with that of United Bank. United previously exited the third-party origination (“TPO”) business during the fourth quarter of 2023.

New Accounting Standards

In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-09, “Improvements to Income Tax Disclosures.” ASU 2023-09 enhances annual income tax disclosures by requiring (1) consistent categories and greater disaggregation of information in the rate reconciliation and (2) income taxes paid disaggregated by jurisdiction. ASU 2023-09 also includes certain other amendments to improve the effectiveness of income tax disclosures. ASU 2023-09 is effective for public business entities for annual periods beginning after December 15, 2024. For entities other than public business entities, the amendments are effective for annual periods beginning after December 15, 2025. Entities are permitted to early adopt the standard for annual financial statements that have not yet been issued or made available for issuance. The adoption of ASU 2023-09 is not expected to have an impact on the Company’s financial condition or results of operations but could change certain disclosures in United’s SEC filings.

10

In November 2023, the FASB issued ASU 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures.” The amendments in ASU 2023-07 improve reportable segment disclosure requirements, mainly through enhanced disclosures about significant segment expenses. In addition, the amendments enhance interim disclosure requirements, clarify circumstances in which an entity can disclose multiple segment measures of profit or loss, provide new segment disclosure requirements for entities with a single reportable segment, and contain other disclosure requirements. The purpose of the amendments will enable investors to better understand an entity’s overall performance and assess potential future cash flows. ASU No. 2023-07 is effective for public business entities for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption of the amendment is permitted. The adoption of ASU 2023-07 is not expected to have an impact on the Company’s financial condition or results of operations but could change certain disclosures in United’s SEC filings starting with its 2024 Annual Report on Form 10-K.

In October 2023, the FASB issued ASU 2023-06, “Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative,” which adopts certain disclosure requirements referred by the SEC. For entities subject to the SEC’s existing disclosure requirements and for entities required to file or furnish financial statements with or to the SEC in preparation for the sale of or for purposes of issuing securities that are not subject to contractual restrictions on transfer, the effective date for each amendment will be the date on which the SEC’s removal of that related disclosure from Regulation S-X or Regulation S-K becomes effective, with early adoption prohibited. For all other entities, the amendments will be effective two years later. The adoption of ASU 2023-06 is not expected to have an impact on the Company’s financial condition or results of operations but could change certain disclosures in United’s SEC filings.

In August 2023, the FASB issued ASU 2023-05, “Business Combinations – Joint Venture Formations (Subtopic 805-60).” ASU 2023-05 requires a joint venture to apply a new basis of accounting at its formation date by valuing the net assets contributed at fair value for both business and asset transactions. The value of the net assets in total is then allocated to individual assets and liabilities by applying Topic 805 with certain exceptions. ASU 2023-05 requires certain disclosures to aid the user of the financial statements in understanding the implications of the joint venture formation. ASU 2023-05 is effective for joint venture formations with a formation date on or after January 1, 2025. The adoption of ASU 2023-05 is not expected to have an impact on the Company’s financial condition or results of operations.

In July 2023, the FASB issued ASU No. 2023-03, “Presentation of Financial Statements (Topic 205), Income Statement—Reporting Comprehensive Income (Topic 220), Distinguishing Liabilities from Equity (Topic 480), Equity (Topic 505), and Compensation—Stock Compensation (Topic 718): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 120, SEC Staff Announcement at the March 24, 2022 EITF Meeting, and Staff Accounting Bulletin Topic 6.B, Accounting Series Release 280—General Revision of Regulation S-X: Income or Loss Applicable to Common Stock.” ASU 2023-03 amends the ASC for SEC updates pursuant to SEC Staff Accounting Bulletin No. 120; SEC Staff Announcement at the March 24, 2022 Emerging Issues Task Force (“EITF”) Meeting; and Staff Accounting Bulletin Topic 6.B, Accounting Series Release 280 - General Revision of Regulation S-X: Income or Loss Applicable to Common Stock. These updates were immediately effective and did not have a significant impact on the Company’s financial statements.

In March 2023, the FASB issued Accounting ASU 2023-02, “Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method.” ASU 2023-02 permits reporting entities to elect to account for their tax equity investments, regardless of the tax credit program from which the income tax credits are received, using the proportional amortization method if certain conditions are met. The amendments in this ASU apply to all reporting entities that hold

11

tax equity investments that meet the conditions for and elect to account for them using the proportional amortization method or an investment in a low income housing tax credit (“LIHTC”) structure through a limited liability entity that is not accounted for using the proportional amortization method and to which certain LIHTC-specific guidance removed from Subtopic 323-740 has been applied. Additionally, the disclosure requirements apply to investments that generate income tax credits and other income tax benefits from a tax credit program for which the entity has elected to apply the proportional amortization method (including investments within that elected program that do not meet the conditions to apply the proportional amortization method). ASU 2023-02 was effective for United on January 1, 2024. The amendments in this update must be applied on either a modified retrospective or a retrospective basis except for LIHTC investments not accounted for using the proportional amortization method. At January 1, 2024, United chose not to elect to account for its tax equity investments using the proportional amortization method.

In December 2022, the FASB issued ASU 2022-06, “Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848.” ASU 2022-06 extends the period of time financial statement preparers can utilize the reference rate reform relief guidance. In 2020, the FASB issued ASU 2020-04 to provide temporary, optional expedients related to the accounting for contract modifications and hedging transactions as a result of the global markets’ anticipated transition away from the use of LIBOR and other interbank offered rates to alternative reference rates. At the time ASU 2020-04 was issued, the United Kingdom’s Financial Conduct Authority (“FCA”) had established the intent that it would no longer be necessary to persuade, or compel, banks to submit to LIBOR after December 31, 2021. As a result, the sunset provision was set for December 31, 2022; 12 months after the expected cessation date of all currencies and tenors of LIBOR. In March 2021, the FCA announced that the intended cessation date of LIBOR in the United States would be June 30, 2023, which has now taken effect as intended. Accordingly, ASU 2022-06 defers the expiration date of ASU 848 to December 31, 2024. United implemented a comprehensive project plan to execute the transition of its LIBOR-based financial instruments to alternative reference rates. United utilized the Secured Overnight Financing Rate (“SOFR”) and Prime as the preferred alternatives to LIBOR.

In June 2022, the FASB issued ASU 2022-03, “Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions.” ASU 2022-03 clarifies that a contractual restriction on the sale of an equity security is not considered part of the unit of account of the equity security and, therefore, is not considered in measuring fair value. ASU 2022-03 also clarifies that an entity cannot, as a separate unit of account, recognize and measure a contractual sale restriction and requires certain new disclosures for equity securities subject to contractual sale restrictions. ASU 2022-03 was effective for United on January 1, 2024. The adoption of ASU 2022-03 did not have a material impact on the Company’s financial condition or results of operations.

For the adoption of ASC Topic 326, “Financial Instruments—Credit Losses,” United made a policy election to exclude accrued interest from the amortized cost basis of available-for-sale debt securities and report accrued interest separately in “Accrued interest receivable” in the consolidated balance sheets. Available-for-sale debt securities are placed on non-accrual status when we no longer expect to receive all contractual amounts due, which is generally at 90 days past due. Accrued interest receivable is reversed against interest income when a security is placed on non-accrual status. Accordingly, United does not currently recognize an allowance for credit loss against accrued interest receivable on available-for-sale debt securities. The table above excludes accrued interest receivable of $19,963 and $20,878 at March 31, 2024 and December 31, 2023, respectively, that is recorded in “Accrued interest receivable.”

The following table shows the proceeds from maturities, sales and calls of available for sale securities and the gross realized gains and losses on sales and calls of those securities that have been included in earnings as a result of any sales and calls. Gains or losses on sales and calls of available for sale securities were recognized by the specific identification method.

	2024		2023
Proceeds from maturities, sales and calls	$	416,410	$	185,748
Gross realized gains		0		0
Gross realized losses		0		420

At March 31, 2024, gross unrealized losses on available for sale securities were $366,788 on 1,071 securities of a total portfolio of 1,124 available for sale securities. Securities with the most significant gross unrealized losses at March 31, 2024 consisted primarily of agency residential mortgage-backed securities, state and political subdivision securities, agency commercial mortgage-backed securities and other corporate securities.

In determining whether or not a security is impaired, management considered the severity of the loss in conjunction with United’s positive intent and the more likely than not ability to hold these securities to recovery of their cost basis or maturity. Generally, the significant amount of gross unrealized losses on available for sale securities at March 31, 2024 was the result of rising interest rates.

State and political subdivisions

United’s state and political subdivisions portfolio relates to securities issued by various municipalities located throughout the United States. The total amortized cost of available for sale state and political subdivision securities was $611,240 at March 31, 2024. As of March 31, 2024, approximately 48% of the portfolio was supported by the general obligation of the issuing municipality, which allows for the securities to be repaid by any means available to the municipality. The majority of the portfolio was rated AA or higher, and no securities within the portfolio were rated below investment grade as of March 31, 2024. In addition to monitoring the credit ratings of these securities, management also evaluates the financial performance of the underlying issuers on an ongoing basis. Based upon management’s analysis and judgment, it was determined that none of the state and political subdivision securities had credit losses at March 31, 2024.

Mortgage-backed securities

The fair value of mortgage-backed securities is affected by changes in interest rates and prepayment speeds. When interest rates decline, prepayment speeds generally accelerate due to homeowners refinancing their mortgages at lower interest rates. This may result in the proceeds being reinvested at lower interest rates. Rising interest rates may decrease the assumed prepayment speed. Slower prepayment speeds may extend the maturity of the security beyond its estimated maturity. Therefore, investors may not be able to invest at current higher market rates due to the extended expected maturity of the security. United had a net unrealized loss of $239,195 on mortgage-backed securities at March 31, 2024. Below is a detailed discussion of mortgage-backed securities by type.

United’s agency mortgage-backed securities portfolio relates to securities issued by Fannie Mae, Freddie Mac, and Ginnie Mae. The total amortized cost of available for sale agency mortgage-backed securities was $1,691,373 at March 31, 2024. Of the $1,691,373 amount, $507,889 was related to agency commercial mortgage-backed securities and $1,183,484 was related to agency residential mortgage-backed securities. Each of the agency mortgage-backed securities provides a guarantee of full and timely payments of principal and interest by the issuing agency. Based upon management’s analysis and judgment, it was determined that none of the agency mortgage-backed securities had credit losses at March 31, 2024.

United’s non-agency residential mortgage-backed securities portfolio relates to securities of various private label issuers. The total amortized cost of available for sale non-agency residential mortgage-backed securities was $83,698 at March 31, 2024. Of the $83,698, 100% was rated AAA. Based upon management’s analysis and judgment, it was determined that none of the non-agency residential mortgage-backed securities had credit losses at March 31, 2024.

Asset-backed securities

As of March 31, 2024, United’s asset-backed securities portfolio had a total amortized cost balance of $837,064. 100% of the portfolio was investment grade rated as of March 31, 2024. Approximately 24% of the portfolio relates to securities that are backed by Federal Family Education Loan Program (“FFELP”) student loan collateral which includes a minimum of a 97% government repayment guaranty, as well as additional credit support and subordination in excess of the government guaranteed portion. Approximately 76% of the portfolio relates to collateralized loan obligation securities that are all AAA rated. Upon reviewing this portfolio as of March 31, 2024, it was determined that none of the asset-backed securities had credit losses.

Single issue trust preferred securities

The majority of United’s single issue trust preferred portfolio consists of obligations from large cap banks (i.e. banks with market capitalization in excess of $10 billion). All single issue trust preferred securities are currently receiving interest payments. The amortized cost of available for sale single issue trust preferred securities as of March 31, 2024 consisted of $7,477 in investment grade bonds, $3,109 in split rated bonds, and $5,804 in unrated bonds. Management reviews each issuer’s current and projected earnings trends, asset quality, capitalization levels, and other key factors. Upon completing the review for the first quarter of 2024, it was determined that none of the single issue trust preferred securities had credit losses.

Other corporate securities

As of March 31, 2024, United’s other corporate securities portfolio had a total amortized cost balance of $301,199. The majority of the portfolio consisted of debt issuances of corporations representing a variety of industries, including financial institutions. Of the $301,199, 96% had at least one rating above investment grade, 1% were below investment grade rated, and 3% were unrated. For other corporate securities, management has evaluated the near-term prospects of the investment in relation to the severity of any unrealized loss. Based upon management’s analysis and judgment, it was determined that none of the other corporate securities had credit losses at March 31, 2024.

The amortized cost and estimated fair value of securities available for sale at March 31, 2024 and December 31, 2023 by contractual maturity are shown as follows. Expected maturities may differ from contractual maturities because the issuers may have the right to call or prepay obligations without penalties.

	March 31, 2024				December 31, 2023
	Amortized Cost		Estimated Fair Value		Amortized Cost		Estimated Fair Value
Due in one year or less	$	431,832	$	429,801	$	497,555	$	493,651

Total	$	3,980,612	$	3,613,975	$	4,149,895	$	3,786,377

Equity securities at fair value

Equity securities consist mainly of mutual funds of Community Reinvestment Act (“CRA”) qualified investments and equity securities within a rabbi trust for the payment of benefits under a deferred compensation plan for certain key officers of United and its subsidiaries. The fair value of United’s equity securities was $8,762 at March 31, 2024 and $8,945 at December 31, 2023.

Other investment securities

During the first quarter of 2024, United evaluated all of its cost method investments to determine if certain events or changes in circumstances during the first quarter of 2024 had a significant adverse effect on the recorded value of any of its cost method securities. United determined that there was no individual security that experienced an adverse event during the first quarter. There were no other events or changes in circumstances during the first quarter which would have an adverse effect on the recorded fair value of its cost method securities.

The carrying value of securities pledged to secure public deposits, securities sold under agreements to repurchase, and for other purposes as required or permitted by law, approximated $2,279,895 and $2,307,591 at March 31, 2024 and December 31, 2023, respectively.

3. LOANS AND LEASES

Major classes of loans and leases are as follows:

	March 31, 2024			December 31, 2023
Commercial, financial and agricultural:
Owner-occupied commercial real estate	$	1,624,746		$	1,598,231
Nonowner-occupied commercial real estate		7,010,266			6,718,343

Total gross loans	$	21,520,076		$	21,359,084

The table above does not include loans held for sale of $44,426 and $56,261 at March 31, 2024 and December 31, 2023, respectively. Loans held for sale consist of single-family residential real estate loans originated for sale in the secondary market.

United’s subsidiary bank has made loans to the directors and officers of United and its subsidiaries, and to their affiliates. The aggregate dollar amount of these loans was $68,274 and $68,460 at March 31, 2024 and December 31, 2023, respectively.

4. CREDIT QUALITY

Management monitors the credit quality of its loans and leases on an ongoing basis. Measurement of delinquency and past due status are based on the contractual terms of each loan. United considers a loan to be past due when it is 30 days or more past its contractual payment due date.

17

For all loan classes, past due loans and leases are reviewed on a monthly basis to identify loans and leases for nonaccrual status. Generally, when collection in full of the principal and interest is jeopardized, the loan is placed on nonaccrual status. The accrual of interest income on commercial and most consumer loans generally is discontinued when a loan becomes 90 to 120 days past due as to principal or interest. However, regardless of delinquency status, if a loan is fully secured and in the process of collection and resolution of collection is expected in the near term (generally less than 90 days), then the loan will not be placed on nonaccrual status. When interest accruals are discontinued, unpaid interest recognized in income in the current year is reversed, and unpaid interest accrued in prior years is charged to the allowance for credit losses. United’s method of income recognition for loans and leases that are classified as nonaccrual is to recognize interest income on a cash basis or apply the cash receipt to principal when the ultimate collectability of principal is in doubt. Nonaccrual loans and leases will not normally be returned to accrual status unless all past due principal and interest has been paid and the borrower has evidenced their ability to meet the contractual provisions of the note.

The following table sets forth United’s age analysis of its past due loans and leases, segregated by class of loans and leases:

In some cases, United will modify a loan to a borrower experiencing financial difficulty by providing multiple types of concessions such as a term extension, principal forgiveness, an interest rate reduction or a combination thereof. The following table presents the amortized cost of loans and leases to borrowers experiencing financial difficulty modified during the first three months of 2024 and 2023, respectively, by class of financing receivable and by type of modification. The percentage of the amortized cost basis of loans and leases that were modified to borrowers experiencing financial difficulty as compared to the amortized cost basis of each class of financing receivable is also represented below.

As of March 31, 2024 and December 31, 2023, there were commitments to lend additional funds of $718 and $28, respectively, to debtors owing loan receivables whose terms have been modified.

United’s estimate of future credit losses uses a lifetime methodology, derived from modeled loan performance based on the extensive historical experience of loans with similar risk characteristics, adjusted to reflect current conditions and reasonable and supportable forecasts. The historical loss experience used in United’s credit loss models includes the impact of loan modifications provided to borrowers experiencing financial difficulty, and also includes the impact of projected loss severities as a result of loan defaults.

United closely monitors the performance of the loans that are modified to borrowers experiencing financial difficulty to understand the effectiveness of its modification efforts. The following table presents the performance in the 12 months after a modification made to borrowers experiencing financial difficulty presented by class of financing receivable:

United elects the practical expedient to measure expected credit losses on collateral dependent loans and leases based on the difference between the loan’s amortized cost and the collateral’s fair value, adjusted for selling costs. The following table presents the amortized cost basis of collateral-dependent loans and leases in which repayment is expected to be derived substantially through the operation or sale of the collateral and where the borrower is experiencing financial difficulty, by class of loans and leases as of March 31, 2024 and December 31, 2023:

United categorizes loans and leases into risk categories based on relevant information about the ability of borrowers to service their debt: current financial information, historical payment experience, credit documentation, underlying collateral (if any), public information and current economic trends, among other factors.

United uses the following definitions for risk ratings:

• Pass

• Special Mention

• Substandard

• Doubtful

For United’s loans with a corporate credit exposure, United analyzes loans individually to classify the loans as to credit risk. Review and analysis of criticized (special mention-rated loans in the amount of $1,000 or greater) and classified (substandard-rated and worse in the amount of $500 and greater) loans is completed once per quarter. Review of notes with committed exposure of $2,000 or greater is completed at least annually. For loans with a consumer credit exposure, United internally assigns a grade based upon an individual loan’s delinquency status. United reviews and updates, as necessary, these grades on a quarterly basis.

Special mention loans, with a corporate credit exposure, have potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loans or in the Company’s credit position at some future date. Borrowers may be experiencing adverse operating trends (declining revenues or margins) or an ill proportioned balance sheet (e.g., increasing inventory without an increase in sales, high leverage, tight liquidity). Adverse economic or market conditions, such as interest rate increases or the entry of a new competitor, may also support a special mention rating. Nonfinancial reasons for rating a credit exposure special mention include management problems, pending litigation, an ineffective loan agreement or other material structural weakness, and any other significant deviation from prudent lending practices. For loans with a consumer credit exposure, loans that are past due 30-89 days are generally considered special mention.

A substandard loan with a corporate credit exposure is inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness, or weaknesses, that jeopardize the liquidation of the debt by the borrower. They are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. They require more intensive supervision by management. Substandard loans are generally characterized by current or expected unprofitable operations, inadequate debt service coverage, inadequate liquidity, or marginal capitalization. Repayment may depend on collateral or other credit risk mitigants. For some substandard loans, the likelihood of full collection of interest and principal may be in doubt and thus, placed on nonaccrual. For loans with a consumer credit exposure, loans that are 90 days or more past due or that have been placed on nonaccrual are considered substandard.

A loan with corporate credit exposure is classified as doubtful if it has all the weaknesses inherent in one classified as substandard with the added characteristic that the weaknesses make collection in full, on the basis of currently existing facts, conditions, and values, highly questionable. A doubtful loan has a high probability of total or substantial loss, but because of specific pending events that may strengthen the loan, its classification as loss is deferred. Doubtful borrowers are usually in default, lack adequate liquidity or capital, and lack the resources necessary to remain an operating entity. Pending events can include mergers, acquisitions, liquidations, capital injections, the perfection of liens on additional collateral, the valuation of collateral, and refinancing. Generally, there are not any loans with a consumer credit exposure that are classified as doubtful. Usually, they are charged-off prior to such a classification.

At March 31, 2024 and December 31, 2023, other real estate owned (“OREO”) included in other assets in the Consolidated Balance Sheets was $2,670 and $2,615, respectively. OREO consists of real estate acquired in foreclosure or other settlement of loans. Such assets are carried at the lower of the investment in the assets or the fair value of the assets less estimated selling costs. Any adjustment to the fair value at the date of transfer is charged against the allowance for loan losses. Any subsequent valuation adjustments as well as any costs relating to operating, holding or disposing of the property are recorded in other expense in the period incurred. At March 31, 2024 and December 31, 2023, the recorded investment of consumer mortgage loans secured by residential real estate properties for which formal foreclosure proceedings are in process was $258 and $142, respectively.

5. ALLOWANCE FOR CREDIT LOSSES

The allowance for loan losses is an estimate of the expected credit losses on financial assets measured at amortized cost to present the net amount expected to be collected as of the balance sheet date. Such allowance is based on the credit losses expected to arise over the life of the asset (contractual term). Assets are charged off when United determines that such financial assets are deemed uncollectible or based on regulatory requirements, whichever is earlier. Charge-offs are recognized as a deduction from the allowance for credit losses. Expected recoveries of amounts previously charged-off, not to exceed the aggregate of the amount previously charged-off, are included in determining the necessary reserve at the balance sheet date.

United made a policy election to present the accrued interest receivable balance separately in its consolidated balance sheets from the amortized cost of a loan. Accrued interest receivable was $91,178 and $88,963 at March 31, 2024 and December 31, 2023, respectively, related to loans and leases are included separately in “Accrued interest receivable” in the consolidated balance sheets. For all classes of loans and leases receivable, the accrual of interest is discontinued when the contractual payment of principal or interest has become 90 days past due, unless the loan is well secured and in the process of collection. Interest received on nonaccrual loans and leases, generally is either applied against principal or reported as interest income, according to management’s judgment as to the collectability of principal.

The following table represents the accrued interest receivable as of March 31, 2024 and December 31, 2023:

	Accrued Interest Receivable
	At March 31, 2024		At December 31, 2023
Commercial Real Estate:
Owner-occupied	$	4,662	$	4,751
Nonowner-occupied		36,089		27,507

United estimates the allowance balance using relevant available information, from internal and external sources, relating to past events, current conditions and reasonable and supportable forecasts. Historical credit loss experience provides the basis for the estimation of expected credit losses. Adjustments to historical loss information are made for differences in current loan-specific risk characteristics such as differences in underwriting standards, portfolio mix, delinquency level or term as well as reasonable and supportable forecast adjustments for changes in environmental conditions, such as changes in unemployment rates, property values or other relevant factors. A reversion to historical loss data occurs via a straight-line method during the year following the one-year reasonable and supportable forecast period.

27

United pools its loans and leases based on similar risk characteristics in estimating expected credit losses. United has identified the following portfolio segments and measures the allowance for credit losses using the following methods:

• Method: Probability of Default/Loss Given Default (PD/LGD)

• Commercial Real Estate Owner-Occupied

• Commercial Real Estate Nonowner-Occupied

• Commercial Other

• Method: Cohort

• Residential Real Estate

• Construction & Land Development

• Consumer

• Bankcard

Risk characteristics of commercial real estate owner-occupied loans and commercial other loans and leases are similar in that they are normally dependent upon the borrower’s internal cash flow from operations to service debt. Commercial real estate nonowner-occupied loans differ in that cash flow to service debt is normally dependent on external income from third parties for use of the real estate such as rents, leases and room rates. Residential real estate loans are dependent upon individual borrowers who are affected by changes in general economic conditions, demand for housing and resulting residential real estate valuation. Construction and land development loans are impacted mainly by demand whether for new residential housing or for retail, industrial, office and other types of commercial construction within a given area. Consumer loan pool risk characteristics are influenced by general, regional and local economic conditions.

Loans that do not share risk characteristics are evaluated on an individual basis. Loans evaluated individually are not also included in the collective evaluation. When management determines that foreclosure is probable or when the borrower is experiencing financial difficulty at the reporting date and repayment is expected to be provided substantially through the operation or sale of the collateral but may also include other non-performing loans, expected credit losses are based on the fair value of the collateral at the reporting date, adjusted for selling costs as appropriate. These individually evaluated loans are removed from their respective pools and typically represent collateral dependent loans.

Expected credit losses are estimated over the contractual term of the loans and leases, adjusted for expected prepayments when appropriate. The contractual term excludes expected extensions, renewals and modifications unless management has a reasonable expectation at the reporting date that the extension or renewal options are included in the original or modified contract at the reporting date and are not unconditionally cancelable by United.

At the acquisition date, an initial allowance for expected credit losses for non-PCD loans is estimated and recorded as credit loss expense. The subsequent measurement of expected credit losses for all acquired loans is the same as the subsequent measurement of expected credit losses for originated loans. For allowance for credit losses under ASC Topic 326 calculation purposes, United includes its acquired loans and leases in their relevant pool unless they meet the criteria for specific review.

United maintains an allowance for loan losses and a reserve for lending-related commitments such as unfunded loan commitments and letters of credit. The reserve for lending-related commitments of $42,915 and $44,706 at March 31, 2024 and December 31, 2023, respectively, is separately classified on the balance sheet and is included in other liabilities. The combined allowance for loan losses and reserve for lending-related commitments is considered the allowance for credit losses.

28

United’s allowance for credit losses at March 31, 2024 was relatively flat from December 31, 2023, increasing $1,877 or less than 1%. This slight increase was due mainly to increases in the loan loss reserves for the commercial real estate, both owner and non-owner occupied, the residential real estate and the other commercial loans segments due to increased outstanding loan balances and increased adjustments resulting from the reasonable and supportable forecast.

The first quarter of 2024 qualitative adjustments include analyses of the following:

• Current conditions – United considered the impact of inflation, interest rates, the banking regulatory environment and geopolitical conflict when making determinations related to factor adjustments for the external environment. United also considered portfolio trends related to economic and business conditions, collateral values for dependent loans; past due, nonaccrual and graded loans and leases; and concentrations of credit.

• Reasonable and supportable forecasts – The forecast is determined on a portfolio-by-portfolio basis by relating the correlation of real GDP and the unemployment rate to loss rates to forecasts of those variables. The reasonable and supportable forecast selection is subjective in nature and requires more judgment compared to the other components of the allowance. Assumptions for the economic variables were the following:

• The forecast for real GDP in 2024 increased in the first quarter, from a projection of 1.40% for 2024 at the end of 2023 to 2.10% for 2024 with a slightly smaller increase for 2025, from a projection of 1.80% for 2025 at the end of 2023 to 2.00% for 2025. The unemployment rate remained fairly consistent to the end of 2023 with a steady trend expected throughout 2024 and 2025.

• Greater risk of loss is probable in the office portfolio due to continued hybrid and remote work that may be exacerbated by future economic conditions as well as higher interest rates and cap rates.

• Reversion to historical loss data occurs via a straight-line method during the year following the one-year reasonable and supportable forecast period.

A progression of the allowance for loan and lease losses, by portfolio segment, for the periods indicated is summarized as follows:

7. MORTGAGE SERVICING RIGHTS

Mortgage loans serviced for others are not included in the accompanying Consolidated Balance Sheets. The value of mortgage servicing rights (“MSRs”) is included on the Company’s Consolidated Balance Sheets.

The Company initially measures servicing assets and liabilities retained related to the sale of residential loans held for sale (“MSRs”) at fair value, if practicable. For subsequent measurement purposes, the Company measures servicing assets and liabilities based on the lower of cost or market using the amortization method. MSRs are amortized in proportion to, and over the period of, estimated net servicing income. The amortization of the MSRs is analyzed periodically and is adjusted to reflect changes in prepayment rates and other estimates.

The Company evaluates potential impairment of MSRs based on the difference between the carrying amount and current estimated fair value of the servicing rights. In determining impairment, the Company aggregates all servicing rights and stratifies them into tranches based on predominant risk characteristics. If impairment exists, a valuation allowance is established for any excess of amortized cost over the current estimated fair value by a charge to income. If the Company later determines that all or a portion of the impairment no longer exists for a particular tranche, a reduction of the allowance may be recorded as an increase to income.

Service fee income is recorded for fees earned for servicing mortgage loans under servicing agreements with the Federal National Mortgage Association (“FNMA”), the Federal Home Loan Mortgage Corporation (“FHLMC”) and certain private investors. The fees are based on a contractual percentage of the outstanding principal balance of the loans serviced and are recorded in noninterest income. Amortization of MSRs and mortgage servicing costs are charged to expense when incurred.

The unpaid principal balances of loans serviced for others were approximately $1,173,246 at March 31, 2024 and $1,202,448 at December 31, 2023.

The estimated fair value of the mortgage servicing rights was $13,439 and $13,427 at March 31, 2024 and December 31, 2023, respectively. The estimated fair value of servicing rights at March 31, 2024 was determined using a net servicing fee of 0.25%, average discount rates ranging from 10.19% to 11.15% with a weighted average discount rate of 10.59%, average constant prepayment rates (“CPR”) ranging from 7.62% to 9.96% with a weighted average prepayment rate of 9.16%, depending upon the stratification of the specific servicing right, and a delinquency rate, including loans on forbearance of 2.65%. The estimated fair value of servicing rights at December 31, 2023 was determined using a net servicing fee of 0.25%, average discount rates ranging from 10.50% to 10.82% with a weighted average discount rate of 10.58%, average constant prepayment rates (“CPR”) ranging from 7.84% to 10.25% with a weighted average prepayment rate of 9.43%, depending upon the stratification of the specific servicing right, and a delinquency rate, including loans on forbearance of 3.29%. Please refer to Note 13 in these Notes to Consolidated Financial Statements for additional information concerning the fair value of MSRs.

31

The following presents the activity in mortgage servicing rights, including their valuation allowance for the three months ended March 31, 2024 and 2023:

	Three Months Ended March 31, 2024			Three Months Ended March 31, 2023
MSRs beginning balance	$	4,554		$	21,022
Amount sold		0			(235	)
Amount capitalized		0			145
Amount amortized		(313	)		(945	)
MSRs ending balance	$	4,241		$	19,987
MSRs valuation allowance beginning balance	$	0		$	0
Aggregate additions charged and recoveries credited to operations		0			0
MSRs impairment		0			0
MSRs valuation allowance ending balance	$	0		$	0
MSRs, net of valuation allowance	$	4,241		$	19,987

The Company did not record any temporary impairments on mortgage servicing rights for the three months ended March 31, 2024 and 2023.

The estimated amortization expense is based on current information regarding future loan payments and prepayments. Amortization expense could change in future periods based on changes in the volume of prepayments and economic factors.

8. LEASES

United determines if an arrangement is a lease at inception. United and certain subsidiaries have entered into various noncancelable-operating leases for branch and loan production offices as well as operating facilities. Operating leases are included in operating lease right-of-use (“ROU”) assets and operating lease liabilities on the Consolidated Balance Sheets. Operating leases with an initial term of 12 months or less are not recorded on the Consolidated Balance Sheets. Presently, United does not have any finance leases.

United’s operating leases are subject to renewal options under various terms. United’s operating leases have remaining terms of 1 to 15 years, some of which include options to extend leases generally for periods of 5 years. United rents or subleases certain real estate to third parties. Our sublease portfolio generally consists of operating leases to other organizations for former branch offices.

ROU assets represent United’s right to use an underlying asset for the lease term and lease liabilities represent United’s obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of United’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The operating lease ROU asset also includes any lease payments made and excludes lease incentives. Lease terms may include options to extend the lease when it is reasonably certain that United will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term.

The components of lease expense were as follows:

			Three Months Ended
	Classification		March 31, 2024			March 31, 2023
Operating lease cost		Net occupancy expense	$	5,671		$	5,392

9. SHORT-TERM BORROWINGS

At March 31, 2024 and December 31, 2023, short-term borrowings were as follows:

	As of March 31, 2024		As of December 31, 2023
Federal funds purchased	$	0	$	0
Securities sold under agreements to repurchase		207,727		196,095
Total short-term borrowings	$	207,727	$	196,095

Federal funds purchased and securities sold under agreements to repurchase have not been a significant source of funds for the company. The securities sold under agreements to repurchase were accounted for as collateralized financial transactions. They were recorded at the amounts at which the securities were acquired or sold plus accrued interest.

United has various unused lines of credit available from certain of its correspondent banks in the aggregate amount of $280,000. These lines of credit, which bear interest at prevailing market rates, permit United to borrow funds in the overnight market, and are renewable annually subject to certain conditions.

33

United has a $20,000 line of credit with an unrelated financial institution to provide for general liquidity needs. The line is an unsecured, revolving line of credit. The line is renewable on a 360 day basis and carries an indexed, floating-rate of interest. The line requires compliance with various financial and nonfinancial covenants. At March 31, 2024, United had no outstanding balance under this credit.

10. LONG-TERM BORROWINGS

United’s subsidiary bank is a member of the Federal Home Loan Bank (“FHLB”). Membership in the FHLB makes available short-term and long-term borrowings from collateralized advances. All FHLB borrowings are collateralized by a mix of single-family residential mortgage loans, commercial loans and investment securities. At March 31, 2024, United had an unused borrowing amount of approximately $7,001,680 available subject to delivery of collateral after certain trigger points. Advances may be called by the FHLB or redeemed by United based on predefined factors and penalties.

At March 31, 2024, $1,460,415 of FHLB advances with a weighted-average contractual interest rate of 5.43% and a weighted-average effective interest rate of 3.70% are scheduled to mature within the next two years. The weighted-average effective rate considers the effect of any interest rate swaps designated as cash flow hedges outstanding at March 31, 2024 to manage interest rate risk on its long-term debt.

The scheduled maturities of these FHLB borrowings are as follows:

Year	Amount
2024	$	1,450,000
2025		10,415
2026		0
2027		0
2028 and thereafter		0
Total	$	1,460,415

At March 31, 2024, United had a total of twenty statutory business trusts that were formed for the purpose of issuing or participating in pools of trust preferred capital securities (“Capital Securities”) with the proceeds invested in junior subordinated debt securities (“Debentures”) of United. The Debentures, which are subordinate and junior in right of payment to all present and future senior indebtedness and certain other financial obligations of United, are the sole assets of the trusts and United’s payment under the Debentures is the sole source of revenue for the trusts. At March 31, 2024 and December 31, 2023, the outstanding balance of the Debentures was $279,019 and $278,616, respectively, and was included in the category of long-term debt on the Consolidated Balance Sheets entitled “Other long-term borrowings.” The Capital Securities are not included as a component of shareholders’ equity in the Consolidated Balance Sheets. United fully and unconditionally guarantees each individual trust’s obligations under the Capital Securities.

Under the provisions of the subordinated debt, United has the right to defer payment of interest on the subordinated debt at any time, or from time to time, for periods not exceeding five years. If interest payments on the subordinated debt are deferred, the dividends on the Capital Securities are also deferred. Interest on the subordinated debt is cumulative.

In accordance with the fully-phased in “Basel III Capital Rules” as published by United’s primary federal regulator, the Federal Reserve, United is unable to consider the Capital Securities as Tier 1 capital, but rather the Capital Securities are included as a component of United’s Tier 2 capital. United can include the Capital Securities in its Tier 2 capital on a permanent basis.

11. COMMITMENTS AND CONTINGENT LIABILITIES

Lending-related Commitments

United is a party to financial instruments with off-balance-sheet risk in the normal course of business to meet the financing needs of its customers and to alter its own exposure to fluctuations in interest rates. These financial instruments include loan commitments, standby letters of credit, and interest rate swap agreements. The instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the financial statements.

United’s maximum exposure to credit loss in the event of nonperformance by the counterparty to the financial instrument for the loan commitments and standby letters of credit is the contractual or notional amount of those instruments. United uses the same policies in making commitments and conditional obligations as it does for on-balance sheet instruments. Collateral may be obtained, if deemed necessary, based on management’s credit evaluation of the counterparty.

Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the commitment contract. Commitments generally have fixed expiration dates or other termination clauses and may require the payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily, and historically do not, represent future cash requirements. The amount of collateral obtained, if deemed necessary upon the extension of credit, is based on management’s credit evaluation of the counterparty. United had approximately $6,817,449 and $6,851,890 of loan commitments outstanding as of March 31, 2024 and December 31, 2023, respectively, approximately 41% of which contractually expire within one year. Excluded in the December 31, 2023 amount above were commitments to extend credit of $416,095 related to mortgage loan funding commitments of United’s previous mortgage banking segment which were of a short-term nature.

Commercial and standby letters of credit are agreements used by United’s customers as a means of improving their credit standing in their dealings with others. Under these agreements, United guarantees certain financial commitments of its customers. A commercial letter of credit is issued specifically to facilitate trade or commerce. Typically, under the terms of a commercial letter of credit, a commitment is drawn upon when the underlying transaction is consummated as intended between the customer and a third party. As of March 31, 2024 and December 31, 2023, United had $16,113 and $16,233 of commercial letters of credit outstanding. A standby letter of credit is generally contingent upon the failure of a customer to perform according to the terms of an underlying contract with a third party. United has issued standby letters of credit of $155,354 and $147,705 as of March 31, 2024 and December 31, 2023, respectively. In accordance with the Contingencies Topic of the FASB Accounting Standards Codification, United has determined that substantially all of its letters of credit are renewed on an annual basis and the fees associated with these letters of credit are immaterial.

Mortgage Banking

Related to its mortgage banking activities, United provides for its estimated exposure to repurchase loans previously sold to investors for which borrowers failed to provide full and accurate information on their loan application or for which appraisals have not been acceptable or where the loan was not underwritten in accordance with the loan program specified by the loan investor, and for other exposure to its investors related to loan sales activities. United evaluates the merits of each claim and estimates its reserve based on actual and expected claims received and considers the historical amounts paid to settle such claims. United’s reserve was immaterial as of March 31, 2024 and December 31, 2023.

United has derivative counter-party risk that may arise from the possible inability of United’s mortgage banking third party investors to meet the terms of their forward sales contracts. United works with mortgage banking third-party investors that are generally well-capitalized, are investment grade and exhibit strong financial performance to mitigate this risk. United does not expect any third-party investor to fail to meet its obligation.

35

Legal Proceedings

United and its subsidiaries are currently involved in various legal proceedings in the normal course of business. On at least a quarterly basis, United assesses its liabilities and contingencies in connection with all pending or threatened claims and litigation, utilizing the most recent information available. On a matter-by-matter basis, an accrual for loss is established for those matters which United believes it is probable that a loss may be incurred and that the amount of such loss can be reasonably estimated. Once established, each accrual is adjusted as appropriate to reflect any subsequent developments. Accordingly, management’s estimate will change from time to time, and actual losses may be more or less than the current estimate. For matters where a loss is not probable, or the amount of the loss cannot be estimated, no accrual is established.

Management is vigorously pursuing all its legal and factual defenses and, after consultation with legal counsel, believes that all such litigation will be resolved with no material effect on United’s financial statements.

Regulatory Matters

A variety of consumer products, including mortgage and deposit products, and certain fees and charges related to such products, have come under increased regulatory scrutiny. It is possible that regulatory authorities could bring enforcement actions, including civil money penalties, or take other actions against United in regard to these consumer products. United could also determine of its own accord, or be required by regulators, to refund or otherwise make remediation payments to customers in connection with these products. It is not possible at this time for management to assess the probability of a material adverse outcome or reasonably estimate the amount of any potential loss related to such matters.

12. DERIVATIVE FINANCIAL INSTRUMENTS

United uses derivative instruments to help aid against adverse price changes or interest rate movements on the value of certain assets or liabilities and on future cash flows. These derivatives may consist of interest rate swaps, caps, floors, collars, futures, forward contracts, written and purchased options. United also executes derivative instruments with its commercial banking customers to facilitate its risk management strategies.

Derivative instruments designated in a hedge relationship to mitigate exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivative instruments designated in a hedge relationship to mitigate exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges.

Fair value hedges may be eligible for offset on the consolidated balance sheets because they are subject to master netting arrangements or similar agreements. United has elected not to offset the assets and liabilities subject to such arrangements on the consolidated financial statements.

During 2020, United entered into two interest rate swap derivatives designated as cash flow hedges. The notional amount of these cash flow hedge derivatives totaled $500,000. The derivatives are intended to hedge the changes in cash flows associated with floating rate FHLB borrowings. As of March 31, 2024, United has determined that no forecasted transactions related to its cash flow hedges resulted in gains or losses pertaining to cash flow hedge reclassification from AOCI to income because the forecasted transactions became probable of not occurring. United estimates that $16,625 will be reclassified from AOCI as a decrease to interest expense over the next 12-months following March 31, 2024 related to the cash flow hedges. As of March 31, 2024, the maximum length of time over which forecasted transactions are hedged is six years.

At inception of a hedge relationship, United formally documents the hedged item, the particular risk management objective, the nature of the risk being hedged, the derivative being used, how effectiveness of the hedge will be assessed

36

and how the ineffectiveness of the hedge will be measured. United also assesses hedge effectiveness at inception and on an ongoing basis using regression analysis. Hedge ineffectiveness is measured by using the change in fair value method. The change in fair value method compares the change in the fair value of the hedging derivative to the change in the fair value of the hedged exposure, attributable to changes in the benchmark rate.

United is subject to the Dodd-Frank Act clearing requirement for eligible derivatives. United has executed and cleared eligible derivatives through the London Clearing House (“LCH”). Variation margin at the LCH is distinguished as settled-to-market and settled daily based on the prior day value, rather than collateralized-to-market. The daily settlement of the derivative exposure does not change or reset the contractual terms of the instrument. The total notional amount of interest rate swap derivatives designated as cash flow hedges cleared through the LCH include $500,000 for asset derivatives as of March 31, 2024. Balances related to LCH are presented as a single unit of account with the fair value of the designated cash flow interest rate swap asset being reduced by variation margin posted by (with) the applicable counterparty and reported in the following table on a net basis. The related fair value on a net basis approximates zero.

United through its mortgage banking channel enters into interest rate lock commitments to finance residential mortgage loans with its customers. These commitments, which contain fixed expiration dates, offer the borrower an interest rate guarantee provided the loan meets underwriting guidelines and closes within the timeframe established by United. Interest rate risk arises on these commitments and subsequently closed loans if interest rates change between the time of the interest rate lock and the delivery of the loan to the investor. Market risk on interest rate lock commitments and mortgage loans held for sale is managed using corresponding forward mortgage loan sales contracts. United is a party to these forward mortgage loan sales contracts to sell loans with servicing either released or retained and short sales of mortgage-backed securities. When the interest rate is locked with the borrower, the rate lock commitment, forward sale agreement, and mortgage-backed security position are undesignated derivatives and marked to fair value through earnings. The fair value of the rate lock derivative is measured using valuations from investors for loans with similar characteristics as well as considering the probability of the loan closing (i.e. the “pull-through” rate) with some adjusted for the Company’s actual sales experience versus the investor’s indicated pricing. Fair values of TBA mortgage-backed securities are measured using valuations from investors for mortgage-backed securities with similar characteristics. Income from mortgage banking activities includes the gain recognized for the period presented and associated elements of fair value.

Derivative contracts involve the risk of dealing with both bank customers and institutional derivative counterparties and their ability to meet contractual terms. Credit risk arises from the possible inability of counterparties to meet the terms of their contracts. United’s exposure is limited to the replacement value of the contracts rather than the notional amount of the contract. The Company’s agreements generally contain provisions that limit the unsecured exposure up to an agreed upon threshold. Additionally, the Company attempts to minimize credit risk through certain approval processes established by management.

For the three months ended March 31, 2024 and 2023, changes in the fair value of any interest rate swaps attributed to hedge ineffectiveness were recorded, but not significant to United’s Consolidated Statements of Income.

13. FAIR VALUE MEASUREMENTS

United determines the fair values of its financial instruments based on the fair value hierarchy established in ASC Topic 820, which also clarifies that fair value of certain assets and liabilities is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants.

ASC Topic 820 specifies a hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect United’s market assumptions.

The three levels of the fair value hierarchy based on these two types of inputs are as follows:

	Level 1	-	Valuation is based on quoted prices in active markets for identical assets and liabilities.
	Level 2	-	Valuation is based on observable inputs including quoted prices in active markets for similar assets and liabilities, quoted prices for identical or similar assets and liabilities in less active markets, and model-based valuation techniques for which significant assumptions can be derived primarily from or corroborated by observable data in the market.
	Level 3	-	Valuation is based on model-based techniques that use one or more significant inputs or assumptions that are unobservable in the market.

When determining the fair value measurements for assets and liabilities, United looks to active and observable markets to price identical assets or liabilities whenever possible and classifies such items in Level 1. When identical assets and liabilities are not traded in active markets, United looks to market observable data for similar assets and liabilities and classifies such items as Level 2. Nevertheless, certain assets and liabilities are not actively traded in observable markets and United must use alternative valuation techniques using unobservable inputs to determine a fair value and classifies such items as Level 3. For assets and liabilities that are not actively traded, the fair value measurement is based primarily upon estimates that require significant judgment. Therefore, the results may not be realized in an actual sale or immediate

39

settlement of the asset or liability. Additionally, there are inherent weaknesses in any calculation technique, and changes in the underlying assumptions used, including discount rates and estimates of future cash flows, could significantly affect the results of current or future values. The level within the fair value hierarchy is based on the lowest level of input that is significant in the fair value measurement.

In accordance with ASC Topic 820, the following describes the valuation techniques used by United to measure certain financial assets and liabilities recorded at fair value on a recurring basis in the financial statements.

Securities available for sale and equity securities: Securities available for sale and equity securities are recorded at fair value on a recurring basis. Fair value measurement is based upon quoted market prices, when available (“Level 1”). If quoted market prices are not available, fair values are measured utilizing independent valuation techniques of identical or similar securities for which significant assumptions are derived primarily from or corroborated by observable market data. Using a market approach valuation methodology, third party vendors compile prices based on observable market inputs, which include benchmark yields, reported trades, issuer spreads, benchmark securities, and “To Be Announced” prices (“Level 2”). Management internally reviews the fair values provided by third party vendors on a monthly basis. Management also performs a quarterly price testing analysis at the individual security level which compares the pricing provided by the third party vendors to an independent pricing source’s valuation of the same securities. Variances that are deemed to be material are reviewed by management. Additionally, to further assess the reliability of the information received from third party vendors, management obtains documentation from third party vendors related to the sources, methodologies, and inputs utilized in valuing securities classified as Level 2. Management analyzes this information to ensure the underlying assumptions appear reasonable. Management also obtains an independent service auditor’s report from third party vendors to provide reasonable assurance that appropriate controls are in place over the valuation process. Upon completing its review of the pricing from third party vendors at March 31, 2024, management determined that the prices provided by its third party pricing sources were reasonable and in line with management’s expectations for the market values of these securities. Therefore, prices obtained from third party vendors that did not reflect forced liquidation or distressed sales were not adjusted materially by management at March 31, 2024. Management utilizes a number of factors to determine if a market is inactive, all of which may require a significant level of judgment. Factors that management considers include: a significant widening of the bid-ask spread, a considerable decline in the volume and level of trading activity in the instrument, a significant variance in prices among market participants, and a significant reduction in the level of observable inputs. Any securities available for sale not valued based upon quoted market prices or third party pricing models that consider observable market data are considered Level 3. Currently, United does not have any available-for-sale securities considered as Level 3.

Loans held for sale: For residential mortgage loans sold, the loans closed are recorded at fair value using the fair value option which is measured using valuations from investors for loans with similar characteristics (“Level 2”) with some adjusted for the Company’s actual sales experience versus the investor’s indicated pricing (“Level 3”). The unobservable input for Level 3 valuations is the Company’s historical sales prices. For March 31, 2024, the range of historical sales prices increased the investor’s indicated pricing by a range of 0.001% to 0.392% with a weighted average increase of 0.140%.

Derivatives: United utilizes interest rate swaps to hedge exposure to interest rate risk and variability of cash flows associated to changes in the underlying interest rate of the hedged item. These hedging interest rate swaps are classified as either a fair value hedge or a cash flow hedge. United utilizes third-party vendors for derivative valuation purposes. These vendors determine the appropriate fair value based on a net present value calculation of the cash flows related to the interest rate swaps using primarily observable market inputs such as interest rate yield curves (“Level 2”). Valuation adjustments to derivative fair values for liquidity and credit risk are also taken into consideration, as well as the likelihood of default by United and derivative counterparties, the net counterparty exposure and the remaining maturities of the positions. Values obtained from third party vendors are typically not adjusted by management. Management internally reviews the derivative values provided by third party vendors on a quarterly basis. All derivative values are tested for reasonableness by management utilizing a net present value calculation.

40

For a fair value hedge, the fair value of the interest rate swap is recognized on the balance sheet as either a freestanding asset or liability with a corresponding adjustment to the hedged financial instrument. Subsequent adjustments due to changes in the fair value of a derivative that qualifies as a fair value hedge are offset in current period earnings either in interest income or interest expense depending on the nature of the hedged financial instrument. For a cash flow hedge, the fair value of the interest rate swap is recognized on the balance sheet as either a freestanding asset or liability with a corresponding adjustment to accumulated other comprehensive income within shareholders’ equity, net of tax. Subsequent adjustments due to changes in the fair value of a derivative that qualifies as a cash flow hedge are offset to accumulated other comprehensive income, net of tax and reclassified into earnings in the same line associated with the forecasted transaction when the forecasted transaction affects earnings.

The Company records its interest rate lock commitments and forward loan sales commitments at fair value determined as the amount that would be required to settle each of these derivative financial instruments at the balance sheet date. In the normal course of business, United, through its mortgage banking channel, enters into contractual interest rate lock commitments to extend credit to borrowers with fixed expiration dates. The commitments become effective when the borrowers “lock-in” a specified interest rate within the timeframes established by the mortgage companies. All borrowers are evaluated for credit worthiness prior to the extension of the commitment. Interest rate risk arises if interest rates move adversely between the time of the interest rate lock by the borrower and the sale date of the loan to the investor. To mitigate the effect of the interest rate risk inherent in providing rate lock commitments to borrowers, United, through its mortgage banking channel, enters into either a forward sales contract to sell loans to investors or a TBA mortgage-backed security. Fair values of TBA mortgage-backed securities are measured using valuations from investors for mortgage-backed securities with similar characteristics (“Level 2”). The forward sales contracts lock in an interest rate and price for the sale of loans similar to the specific rate lock commitments. These valuations fall into a Level 2 category. The interest rate lock commitments are recorded at fair value which is measured using valuations from investors for loans with similar characteristics (“Level 2”) with some adjusted for the Company’s actual sales experience versus the investor’s indicated pricing (“Level 3”). The unobservable input for Level 3 valuations is the Company’s historical sales prices. For March 31, 2024, the range of historical sales prices increased the investor’s indicated pricing by a range of 0.001% to 0.392% with a weighted average increase of 0.140%.

For interest rate swap derivatives that are not designated in a hedge relationship within United’s mortgage banking activities, changes in the fair value of the derivatives are recognized in income from mortgage banking activities in the same period as the change in the fair value. Unrealized gains and losses due to changes in the fair value of other derivative financial instruments not in hedge relationships are included in noninterest income and noninterest expense, respectively.

The following tables present the balances of financial assets and liabilities measured at fair value on a recurring basis as of March 31, 2024 and December 31, 2023, segregated by the level of the valuation inputs within the fair value hierarchy.

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis

Certain financial assets are measured at fair value on a nonrecurring basis in accordance with GAAP. Adjustments to the fair value of these assets usually result from the application of lower-of-cost-or-market accounting or write-downs of individual assets.

44

The following describes the valuation techniques used by United to measure certain financial assets recorded at fair value on a nonrecurring basis in the financial statements.

Individually assessed loans: In the determination of the allowance for loan losses, loans that do not share risk characteristics are evaluated on an individual basis. Loans evaluated individually are not also included in the collective evaluation. When management determines that foreclosure is probable or when the borrower is experiencing financial difficulty at the reporting date and repayment is expected to be provided substantially through the operation or sale of the collateral, expected credit losses are based on the fair value of the collateral at the reporting date, adjusted for selling costs as appropriate. Fair value is measured using a market approach based on the value of the collateral securing the loans. Collateral may be in the form of real estate or business assets including equipment, inventory, and accounts receivable. The vast majority of the collateral is real estate. The value of real estate collateral is determined utilizing an appraisal conducted by an independent, licensed appraiser outside of the Company using comparable property sales (“Level 2”). However, if the collateral is a house or building in the process of construction or if an appraisal of the real estate property is over two years old, then the fair value is considered Level 3. The value of business equipment is based upon an outside appraisal if deemed significant, or the net book value on the applicable business’ financial statements if not considered significant using observable market data. Likewise, values for inventory and accounts receivables collateral are based on financial statement balances or aging reports (“Level 3”). For individually assessed loans, a specific reserve is established through the allowance for loan losses, if necessary, by estimating the fair value of the underlying collateral on a nonrecurring basis. Any fair value adjustments are recorded in the period incurred as provision for credit losses expense on the Consolidated Statements of Income.

OREO: OREO consists of real estate acquired in foreclosure or other settlement of loans. Such assets are carried on the balance sheet at the lower of the investment in the assets or the fair value of the assets less estimated selling costs. Fair value is determined by one of two market approach methods depending on whether the property has been vacated and an appraisal can be conducted. If the property has yet to be vacated and thus an appraisal cannot be performed, a Brokers Price Opinion (i.e. BPO), is obtained. A BPO represents a best estimate valuation performed by a realtor based on knowledge of current property values and a visual examination of the exterior condition of the property. Once the property is subsequently vacated, a formal appraisal is obtained and the recorded asset value appropriately adjusted. On the other hand, if the OREO property has been vacated and an appraisal can be conducted, the fair value of the property is determined based upon the appraisal using a market approach. An authorized independent appraiser conducts appraisals for United. Appraisals for property other than ongoing construction are based on consideration of comparable property sales (“Level 2”). In contrast, valuation of ongoing construction assets requires some degree of professional judgment. In conducting an appraisal for ongoing construction property, the appraiser develops two appraised amounts: an “as is” appraised value and a “completed” value. Based on professional judgment and their knowledge of the particular situation, management determines the appropriate fair value to be utilized for such property (“Level 3”). As a matter of policy, valuations are reviewed at least annually and appraisals are generally updated on a bi-annual basis with values lowered as necessary.

Intangible Assets: For United, intangible assets consist of goodwill and core deposit intangibles. Goodwill is tested for impairment at least annually or sooner if indicators of impairment exist. United may elect to perform a qualitative analysis to determine whether or not it is more-likely-than not that the fair value of a reporting unit is less than its carrying amount. If United elects to bypass this qualitative analysis, or concludes via qualitative analysis that it is more-likely-than-not that the fair value of a reporting unit is less than its carrying value, United may use either a market or income quantitative approach to determine the fair value of the reporting unit. If the fair value of the reporting unit is less than its carrying value, an impairment charge would be recorded for the difference, not to exceed the amount of goodwill allocated to the reporting unit. At each reporting date, the Company considers potential indicators of impairment. United performed its annual goodwill impairment test on the Company’s reporting units as of September 30, 2023. The goodwill impairment test did not identify any goodwill impairment. In subsequent periods, economic uncertainty, market volatility and the performance of the Company’s stock as well as possible other impairment indicators could cause us to perform a goodwill impairment test which could result in an impairment charge being recorded for that period if the carrying value of goodwill was found to exceed fair value. Core deposit intangibles relate to the estimated value of the deposit base of acquired institutions. Management reviews core deposit intangible assets on an annual basis, or sooner if indicators of

45

impairment exist, and evaluates changes in facts and circumstances that may indicate impairment in the carrying value. During the fourth quarter of 2023, United’s management formulated a plan to consolidate its mortgage delivery channels by consolidating George Mason’s and Crescent’s mortgage banking business into United Bank. As a result of this consolidation decision, United impaired the trade names intangibles at George Mason and Crescent to zero at December 31, 2023. No fair value measurement of intangible assets was made during the first three months of 2024 and 2023.

Mortgage Servicing Rights (“MSRs”): A mortgage servicing right asset represents the amount by which the present value of the estimated future net cash flows to be received from servicing loans are expected to more than adequately compensate the Company for performing the servicing. The Company initially measures servicing assets and liabilities retained related to the sale of residential loans held for sale (“mortgage servicing rights”) at fair value. For subsequent measurement purposes, the Company measures servicing assets and liabilities using the amortization method on a quarterly basis. The quarterly determination of fair value of servicing rights is provided by a third party and is estimated using a present value cash flow model. The most important assumptions used in the valuation model are the anticipated rate of the loan prepayments and discount rates. Although some assumptions in determining fair value are based on standards used by market participants, some are based on unobservable inputs and therefore are classified in Level 3 of the valuation hierarchy. The unobservable inputs for Level 3 valuations are market discount rates, anticipated prepayment speeds, projected delinquency rates, and ancillary fee income net of servicing costs. For the unobservable inputs used in the valuation of mortgage servicing rights at March 31, 2024 and December 31, 2023, refer to Note 7 of these Notes to Consolidated Financial Statements. The Company did not record any temporary impairment of mortgage servicing rights in the quarter ended March 31, 2024 and 2023.

Fair Value of Other Financial Instruments

The following methods and assumptions were used by United in estimating its fair value disclosures for other financial instruments:

Cash and Cash Equivalents: The carrying amounts reported in the balance sheet for cash and cash equivalents approximate those assets’ fair values.

46

Securities held to maturity and other securities: The estimated fair values of securities held to maturity are based on quoted market prices, where available. If quoted market prices are not available, fair values are measured utilizing independent valuation techniques of identical or similar securities for which significant assumptions are derived primarily from or corroborated by observable market data. Third party vendors compile prices from various sources and may determine the fair value of identical or similar securities by using pricing models that consider observable market data. Any securities held to maturity, not valued based upon the methods above, are valued based on a discounted cash flow methodology using appropriately adjusted discount rates reflecting nonperformance and liquidity risks. Other securities consist mainly of shares of Federal Home Loan Bank and Federal Reserve Bank stock that do not have readily determinable fair values and are carried at cost.

Loans and leases: The fair values of certain mortgage loans (e.g., one-to-four family residential), credit card loans, and other consumer loans are based on quoted market prices of similar loans sold in conjunction with securitization transactions, adjusted for differences in loan characteristics. The fair values of other loans and leases (e.g., commercial real estate and rental property mortgage loans, commercial and industrial loans, financial institution loans and agricultural loans) are estimated using discounted cash flow analyses, using market interest rates currently being offered for loans and leases with similar terms to borrowers of similar creditworthiness, which include adjustments for liquidity concerns. For acquired PCD loans, fair value is assumed to equal United’s carrying value, which represents the present value of expected future principal and interest cash flows, as adjusted for any Allowance for Credit Losses recorded for these loans.

Deposits: The fair values of demand deposits (e.g., interest and noninterest checking, regular savings and certain types of money market accounts) are, by definition, equal to the amount payable on demand at the reporting date (i.e., their carrying amounts). The carrying amounts of variable-rate, fixed-term money market accounts and certificates of deposit approximate their fair values at the reporting date. Fair values of fixed-rate certificates of deposit are estimated using a discounted cash flow calculation that applies interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities on time deposits.

Short-term Borrowings: The carrying amounts of federal funds purchased, borrowings under repurchase agreements and any other short-term borrowings approximate their fair values.

Long-term Borrowings: The fair values of United’s Federal Home Loan Bank borrowings and trust preferred securities are estimated using discounted cash flow analyses, based on United’s current incremental borrowing rates for similar types of borrowing arrangements.

14. STOCK BASED COMPENSATION

On May 12, 2020, United’s shareholders approved the 2020 Long-Term Incentive Plan (“2020 LTI Plan”). The 2020 LTI Plan became effective May 13, 2020. An award granted under the 2020 LTI Plan may consist of any non-qualified stock options or incentive stock options, stock appreciation rights (“SARs”), restricted stock, restricted stock units, performance units or other-stock-based award. These awards all relate to the common stock of United. The maximum number of shares of United common stock which may be issued under the 2020 LTI Plan is 2,300,000. The 2020 LTI Plan will be administered by a board committee appointed by United’s Board of Directors (the “Board”). Unless otherwise determined by the Board, the Compensation Committee of the Board (the “Committee”) shall administer the 2020 LTI Plan. The maximum number of options and stock appreciation rights, in the aggregate, which may be awarded to any individual key employee during any calendar year is 100,000. The maximum number of options and stock appreciation rights, in the aggregate, which may be awarded to any non-employee director during any calendar year is 10,000 or, if such Award is payable in cash, the Fair Market Value equivalent thereof. The maximum number of shares of restricted stock or shares subject to a restricted stock units award that may be granted during any calendar year is 225,000 shares to any individual key employee and 10,000 shares to any individual non-employee director. Subject to certain change in control provisions, the 2020 LTI Plan provides that all awards of will vest as the Committee determines in the award agreement, provided that no awards will vest sooner than 1/3 per year over the first three anniversaries of the award. United adopted a clawback policy that applies to named executive officers and other executive officers and permits the Committee to cancel certain awards and to recoup gains realized from previous awards should United be required to prepare an accounting restatement due to materially inaccurate performance metrics. A Form S-8 was filed on May 29, 2020 with the Securities and Exchange Commission to register all the shares which were available for the 2020 LTI Plan. The 2020 LTI Plan replaces the 2016 LTI Plan.

48

Compensation expense of $3,266 and $2,713 related to the nonvested awards under United’s Long-Term Incentive Plans was incurred for the first quarter of 2024 and 2023, respectively. Compensation expense was included in employee compensation in the unaudited Consolidated Statements of Income.

Stock Options

United currently has options outstanding from various option plans other than the 2020 LTI Plan (the “Prior Plans”); however, no common shares of United stock are available for grants under the Prior Plans as these plans have expired. Awards outstanding under the Prior Plans will remain in effect in accordance with their respective terms. The maximum term for options granted under the plans is ten (10) years.

A summary of activity under United’s stock option plans as of March 31, 2024, and the changes during the first three months of 2024 are presented below:

	Three Months Ended March 31, 2024

Exercisable at March 31, 2024		1,307,914		$	3,440		3.6	$	35.66

The following table summarizes the status of United’s nonvested stock option awards during the first three months of 2024:

	Shares			Weighted-Average Grant Date Fair Value Per Share
Nonvested at January 1, 2024		56,526		$	5.65
Vested		(56,526	)		5.65
Forfeited or expired		0			0.00
Nonvested at March 31, 2024		0		$	0.00

During the three months ended March 31, 2024 and 2023, 25,991 and 55,796 shares, respectively, were issued in connection with stock option exercises. All shares issued in connection with stock option exercises for the three months ended March 31, 2024 and 2023 were issued from authorized and unissued stock. The total intrinsic value of options exercised under the Plans during the three months ended March 31, 2024 and 2023 was $207 and $722 respectively.

As of March 31, 2024, there was no unrecognized compensation cost related to nonvested stock option awards.

Restricted Stock

Under the 2020 LTI Plan, United may award restricted common shares to key employees and non-employee directors. Restricted shares granted to participants will vest no sooner than 1/3 per year over the first three anniversaries of the award. Unless determined by the Committee or the Board and provided in the award agreement, recipients of restricted shares do not pay any consideration to United for the shares, have the right to vote all shares subject to such grant and receive all dividends with respect to such shares, whether or not the shares have vested. Presently, these nonvested participating securities have an immaterial impact on diluted earnings per share. As of March 31, 2024, the total unrecognized compensation cost related to nonvested restricted stock awards was $10,971 with a weighted-average expense recognition period of 1.6 years.

49

The following summarizes the changes to United’s nonvested restricted common shares for the period ended March 31, 2024:

	Shares			Weighted-Average Grant Date Fair Value Per Share
Nonvested at January 1, 2024		333,932		$	37.75
Granted		183,908			34.36
Vested		(187,258	)		36.60
Forfeited		(5,215	)		36.48
Nonvested at March 31, 2024		325,367		$	36.51

Restricted Stock Units

Under the 2020 LTI Plan, United may grant restricted stock units (“RSUs”) to key employees. These awards help align the interests of these employees with the interests of the shareholders of United by providing economic value directly related to the performance of the Company. These RSU grants could be time-vested RSUs, performance-vested RSUs, or a combination of both. Currently, time-vested RSUs vest ratably over three years from the date of grant. Performance-vested RSUs cliff-vest after assessment of the Company’s performance over a period of three years. The number of performance-vested RSUs that vest is determined by two metrics measured relative to peers: Return on Average Tangible Common Equity (“ROATCE”) and Total Shareholder Return (“TSR”). Based on ASC Topic 718, the ROATCE comparison is considered a performance condition while the TSR comparison is considered a market condition. There will be no payout of the performance-vested awards if the threshold performance is not achieved. United communicates the specific threshold, target, and maximum performance-vested RSU awards and performance targets to the applicable key employees at the beginning of a performance period. Dividends are accrued but not paid in respect to the awards until the RSUs vest. The holder does not have the right to vote the shares during the time and performance periods. The value of the time-vested RSUs and the performance-vested, based on the performance condition, RSUs awarded is established as the fair market value of the stock at the time of the grant. The value of the performance-vested, based on the market condition, RSUs awarded is estimated through the use of a Monte Carlo valuation model as of the grant date. The Company recognizes expense on the RSUs in accordance with ASC Topic 718.

The following table summarizes the status of United’s nonvested RSUs during the first three months of 2024:

	Shares			Weighted-Average Grant Date Fair Value Per Share
Nonvested at January 1, 2024		363,502		$	37.53
Granted		254,592			32.80
Vested		(127,536	)		36.28
Forfeited or expired		(439	)		34.72
Nonvested at March 31, 2024		490,119		$	35.41

As of March 31, 2024, the total unrecognized compensation cost related to nonvested restricted stock units was $13,314 with a weighted-average expense recognition period of 2.0 years.

15. EMPLOYEE BENEFIT PLANS

United has a defined benefit retirement plan covering qualified employees hired prior to October 1, 2007. Pension benefits are based on years of service and the average of the employee’s highest five consecutive plan years of basic compensation paid during the ten plan years preceding the date of determination. Contributions are intended to provide not only for benefits attributed to service to date, but also for those expected to be earned in the future. No discretionary contributions were made during the first quarter of 2024 and 2023.

19. VARIABLE INTEREST ENTITIES

Variable interest entities (“VIEs”) are entities that either have a total equity investment that is insufficient to permit the entity to finance its activities without additional subordinated financial support or whose equity investors lack the characteristics of a controlling financial interest (i.e., ability to make significant decisions, through voting rights, right to receive the expected residual returns of the entity, and obligation to absorb the expected losses of the entity). VIEs can be structured as corporations, trusts, partnerships, or other legal entities. United’s business practices include relationships with certain VIEs. For United, the business purpose of these relationships primarily consists of funding activities in the form of issuing trust preferred securities.

United currently sponsors twenty statutory business trusts that were created for the purpose of raising funds that originally qualified for Tier I regulatory capital. As previously discussed, these trusts now are considered Tier II regulatory capital. These trusts, of which several were acquired through bank acquisitions, issued or participated in pools of trust preferred capital securities to third-party investors with the proceeds invested in junior subordinated debt securities of United. The Company, through a small capital contribution, owns 100% of the voting equity shares of each trust. The assets, liabilities, operations, and cash flows of each trust are solely related to the issuance, administration, and repayment of the preferred equity securities held by third-party investors. United fully and unconditionally guarantees the obligations of each trust and is obligated to redeem the junior subordinated debentures upon maturity.

53

United does not consolidate these trusts as it is not the primary beneficiary of these entities because United’s wholly owned and indirect wholly owned statutory trust subsidiaries do not have a controlling financial interest in the VIEs. A controlling financial interest is present when an enterprise has both the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and an obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE. The enterprise with a controlling financial interest, known as the primary beneficiary, consolidates the VIE. At March 31, 2024 and December 31, 2023, United’s investment (maximum exposure to loss) in these trusts were $11,876 and $11,751, respectively.

Information related to United’s statutory trusts is presented in the table below:

United, through its banking subsidiary, also makes limited partner equity investments in various low income housing and community development partnerships sponsored by independent third-parties. United invests in these partnerships to either realize tax credits on its consolidated federal income tax return or for purposes of earning a return on its investment. These partnerships are considered VIEs as the limited partners lack a controlling financial interest in the entities through their inability to make decisions that have a significant effect on the operations and success of the partnerships. United’s limited partner interests in these entities is immaterial; however, these partnerships are not consolidated as United is not deemed to be the primary beneficiary. At March 31, 2024 and December 31, 2023, United’s investment (maximum exposure to loss) in these low income housing and community development partnerships were $90,919 and $87,554, respectively, while related unfunded commitments were $65,039 and $63,539, respectively. As of March 31, 2024, United expects to recover its remaining investments through the use of the tax credits that are generated by the investments.

20. SUBSEQUENT EVENT

Agreement to Acquire Piedmont Bancorp, Inc.

On May 9, 2024, United entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Piedmont Bancorp, Inc., a Georgia corporation (“Piedmont”). The Merger Agreement provides that, upon the terms and subject to the conditions set forth therein, Piedmont will merge with and into United (the “Merger”), with United as the surviving corporation in the Merger. Immediately following the Merger, Piedmont’s wholly-owned subsidiary, The Piedmont Bank, a state bank chartered under the laws of the State of Georgia, will merge with and into United’s wholly-owned subsidiary, United Bank, a state bank chartered under the laws of the Commonwealth of Virginia (the “Bank Merger”), with United Bank as the surviving bank in the Bank Merger. The Merger Agreement was approved and adopted by the board of directors of each of United and Piedmont.

Piedmont is a well-capitalized, single bank holding company headquartered in Atlanta, Georgia with total assets of approximately $2.1 billion, total loans of approximately $1.7 billion, total liabilities of approximately $1.9 billion, total deposits of approximately $1.8 billion, and total shareholders’ equity of approximately $195 million as of March 31, 2024. Piedmont is the holding company for The Piedmont Bank, a Georgia state-chartered bank, with sixteen locations in the State of Georgia.

Subject to the terms and conditions of the Merger Agreement, at the effective time of the Merger (the “Effective Time”), each share of common stock, $0.01 par value, of Piedmont (“Piedmont Common Stock”) outstanding immediately prior to the Effective Time, other than certain shares of Piedmont Common Stock held by United and its subsidiaries, will be converted into the right to receive, without interest, (a) 0.300 of a share (the “Exchange Ratio”) of common stock, $2.50 par value, of United (“United Common Stock” and such consideration is hereinafter referred to as the “Merger Consideration”) and (b) cash in lieu of fractional shares.

At the Effective Time, (i) each option to purchase shares of Piedmont Common Stock will fully vest and will be cashed out based on a formula that takes into account the difference between the exercise price and the volume-weighted average of the closing sales price on Nasdaq of United Common Stock for the 10 full trading days ending on the second trading day immediately preceding the Effective Time and the Exchange Ratio, (ii) each warrant to purchase shares of Piedmont Common Stock will fully vest and holders will have the option to convert into the right to receive shares of United Common Stock based on the exchange ratio or be cashed out based on the same formula applicable to option holders, and (iii) each restricted stock grant, restricted stock unit grant and any other outstanding equity award with respect to Piedmont Common Stock that is subject to vesting will fully vest and be entitled to receive the Merger Consideration.

The completion of the Merger and the Bank Merger are subject to the satisfaction of customary closing conditions, including receipt of regulatory approvals from the Board of Governors of the Federal Reserve System and the Virginia Bureau of Financial Institutions, regulatory filings with the Georgia Department of Banking and Finance, and the approval by the stockholders of Piedmont.

Item 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

FORWARD-LOOKING STATEMENTS

Congress passed the Private Securities Litigation Act of 1995 to encourage corporations to provide investors with information about the company’s anticipated future financial performance, goals, and strategies. The act provides a safe haven for such disclosure; in other words, protection from unwarranted litigation if actual results are not the same as management expectations.

United desires to provide its shareholders with sound information about past performance and future trends. Consequently, any forward-looking statements contained in this report, in a report incorporated by reference to this report, or made by management of United in this report, in any other

55

reports and filings, in press releases and in oral statements, involve numerous assumptions, risks and uncertainties. Forward-looking statements can be identified by the use of the words “expect,” “may,” “could,” “intend,” “project,” “estimate,” “believe,” “anticipate,” and other words of similar meaning. Such forward-looking statements are based on assumptions and estimates, which although believed to be reasonable, may turn out to be incorrect. Therefore, undue reliance should not be placed upon these estimates and statements. United cannot assure that any of these statements, estimates, or beliefs will be realized and actual results may differ from those contemplated in these “forward-looking statements.” United undertakes no obligation to publicly update any forward-looking statements, whether as a result of new information, future events, or otherwise.

RECENT DEVELOPMENTS

During the first quarter of 2024, United consolidated its mortgage delivery channels by consolidating George Mason’s and Crescent’s mortgage origination and sales business with United Bank. United had previously exited the third-party origination (“TPO”) business during the fourth quarter of 2023 as part of this consolidation. United continues to offer mortgage products through its bank mortgage channel with previous George Mason offices re-branded under the United umbrella. The consolidation streamlined operations and will enhance the customer experience.

Based on this consolidation of its mortgage delivery channels and an analysis performed at March 31, 2024 in accordance with ASC 280, “Segment Reporting,” United has concluded that it operates only in one reportable segment – community banking. 

INTRODUCTION

The following discussion and analysis presents the significant changes in financial condition and the results of operations of United and its subsidiaries for the periods indicated below. This discussion and the unaudited consolidated financial statements and the notes to unaudited Consolidated Financial Statements include the accounts of United Bankshares, Inc. and its wholly-owned subsidiaries, unless otherwise indicated. Management has evaluated all significant events and transactions that occurred after March 31, 2024, but prior to the date these financial statements were issued, for potential recognition or disclosure required in these financial statements.

This discussion and analysis should be read in conjunction with the unaudited Consolidated Financial Statements and accompanying notes thereto, which are included elsewhere in this document.

USE OF NON-GAAP FINANCIAL MEASURES

This discussion and analysis contains certain financial measures that are not recognized under GAAP. Under SEC Regulation G, public companies making disclosures containing financial measures that are not in accordance with GAAP must also disclose, along with each “non-GAAP” financial measure, certain additional information, including a reconciliation of the non-GAAP financial measure to the closest comparable GAAP financial measure, as well as a statement of the company’s reasons for utilizing the non-GAAP financial measure.

56

Generally, United has presented a non-GAAP financial measure because it believes that this measure provides meaningful additional information to assist in the evaluation of United’s results of operations or financial position. Presentation of a non-GAAP financial measure is consistent with how United’s management evaluates its performance internally and this non-GAAP financial measure is frequently used by securities analysts, investors and other interested parties in the evaluation of companies in the banking industry. Specifically, this discussion contains certain references to financial measures identified as tax-equivalent (“FTE”) net interest income and return on average tangible equity. 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 discussion 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.

Average tangible equity is calculated as GAAP total shareholders’ equity minus total intangible assets. Tangible equity can thus be considered a more conservative valuation of the company. When considering net income, a return on average tangible equity can be calculated. Management provides a return on average equity to facilitate the understanding of as well as to assess the quality and composition of United’s capital structure. This measure, along with others, is used by management to analyze capital adequacy and performance.

However, this non-GAAP information should be considered supplemental in nature and not as a substitute for related financial information prepared in accordance with GAAP. Where the non-GAAP financial measure is used, the comparable GAAP financial measure, as well as reconciliation to that comparable GAAP financial measure, as well as a statement of the company’s reasons for utilizing the non-GAAP financial measure, can be found within this discussion and analysis. Investors should recognize that United’s presentation of this non-GAAP financial measure might not be comparable to a similarly titled measure at other companies.

APPLICATION OF CRITICAL ACCOUNTING POLICIES

The accounting and reporting policies of United conform with U.S. generally accepted accounting principles. In preparing the consolidated financial statements, management is required to make estimates, assumptions and judgments that affect the amounts reported in the financial statements and accompanying notes. These estimates, assumptions and judgments, which are reviewed with the Audit Committee of the Board, are based on information available as of the date of the financial statements. Actual results could differ from these estimates. These policies, along with the disclosures presented in the financial statement notes and in this financial review, provide information on how significant assets and liabilities are valued in the financial statements and how those values are determined. Based on the valuation techniques used and the sensitivity of financial statement amounts to the methods, assumptions, and estimates underlying those amounts, management has identified the determination of the allowance for loan and lease losses, the calculation of the income tax provision, and the use of fair value measurements to account for certain financial instruments to be the accounting areas that require the most subjective or complex judgments, and as such could be most subject to revision as new information becomes available.

United’s critical accounting policies involving the significant judgments and assumptions used in the preparation of the Consolidated Financial Statements as of March 31, 2024 were unchanged from the policies disclosed in United’s Annual Report on Form 10-K for the year ended December 31, 2023 within the section “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

57

FINANCIAL CONDITION

United’s total assets as of March 31, 2024 were $30.03 billion, which was an increase of $102.32 million or less than 1% from December 31, 2023. This increase was mainly due to an increase of $133.70 million or 8.36% in cash and cash equivalents and an increase of $160.99 million or less than 1% in portfolio loans. These increases in assets were partly offset by a $171.24 million or 4.15% decrease in investment securities, an $11.84 million or 21.04% decrease in loans held for sale, and a $10.98 million or 3.97% decrease in other assets. Total liabilities increased $66.12 million or less than 1% from year-end 2023. Deposits increased $100.43 million or less than 1% and accrued expenses and other liabilities increased $6.14 million or 2.88%, which were partially offset by a $38.04 million or 1.92% decrease in borrowings. Shareholders’ equity increased $36.20 million or less than 1%.

The following discussion explains in more detail the changes in financial condition by major category.

Cash and Cash Equivalents

Cash and cash equivalents at March 31, 2024 increased $133.70 million or 8.36% from year-end 2023. In particular, interest-bearing deposits with other banks increased $152.69 million or 11.39% as United placed more cash in an interest-bearing account with the Federal Reserve while cash and due from banks decreased $19.01 million or 7.39%. Federal funds sold increased $16 thousand or 1.37%. During the first three months of 2024, net cash of $124.37 million and $11.77 million were provided by operating and financing activities, respectively, while net cash of $2.43 million was used in investing activities. See the unaudited Consolidated Statements of Cash Flows for data on cash and cash equivalents provided and used in operating, investing and financing activities for the first three months of 2024 and 2023.

Securities

Total investment securities at March 31, 2024 decreased $171.24 million or 4.15%. Securities available for sale decreased $172.40 million or 4.55%. This change in securities available for sale reflects $248.05 million in purchases, $416.41 million in sales, maturities and calls of securities, and a decrease of $3.12 million in market value. The majority of the purchase activity was related to obligations of U.S. Government corporations and agencies. Equity securities were $8.76 million at March 31, 2024, a decrease of $183 thousand or 2.05% due mainly to a net decrease in fair value. Other investment securities were relatively flat from year-end 2023, increasing $1.35 million or less than 1% due to net purchases of investment tax credits.

The following table summarizes the changes in the available for sale securities since year-end 2023:

In addition to the single issue trust preferred securities, the Company held positions in various other corporate securities, including asset-backed securities with an amortized cost of $837.06 million and a fair value of $830.93 million and other corporate securities, with an amortized cost of $301.20 million and a fair value of $269.42 million.

United’s available for sale single issue trust preferred securities had a fair value of $15.33 million as of March 31, 2024. Of the $15.33 million, $7.11 million or 46.36% were investment grade; $3.04 million or 19.82% were split rated; and $5.18 million or 33.82% were unrated. The two largest exposures accounted for 80.19% of the $15.33 million. These included Truist Bank at $7.11 million and Emigrant Bank at $5.18 million. All single issue trust preferred securities are currently receiving full scheduled principal and interest payments.

During the first quarter of 2024, United did not recognize any credit losses on its available for sale investment securities. Management does not believe that any individual security with an unrealized loss as of March 31, 2024 is impaired. United believes the decline in value resulted from changes in market interest rates, credit spreads and liquidity, not a deterioration of credit. Based on a review of each of the securities in the available for sale investment portfolio, management concluded that it was more-likely-than-not that it would be able to realize the cost basis investment and appropriate interest payments on such securities. United has the intent and the ability to hold these securities until such time as the value recovers or the securities mature. As of March 31, 2024, there was no allowance for credit losses related to the Company’s available for sale securities. However, United acknowledges that any securities in an unrealized loss position may be sold in future periods in response to significant, unanticipated changes in asset/liability management decisions, unanticipated future market movements or business plan changes.

Further information regarding the amortized cost and estimated fair value of investment securities, including remaining maturities as well as a more detailed discussion of management’s impairment analysis, is presented in Note 2 to the unaudited Notes to Consolidated Financial Statements.

Other Assets

Other assets decreased $10.98 million or 3.97% from year-end 2023. Income tax receivable decreased $9.42 million due to timing differences, accounts receivable decreased $1.54 million, and dealer reserve decreased $2.09 million due to a decrease in indirect automobile financing. In addition, core deposit intangibles decreased $910 thousand due to amortization. Partially offsetting these decreases was an increase of $1.68 million in other prepaid assets, a $986 thousand increase in deferred tax assets, and a $208 thousand increase in derivative assets due to an increase in fair value.

60

Deposits

Deposits represent United’s primary source of funding. Total deposits at March 31, 2024 increased $100.43 million or less than 1%. In terms of composition, noninterest-bearing deposits decreased $131.73 million or 2.14% while interest-bearing deposits increased $232.16 million or 1.39% from December 31, 2023.

Noninterest-bearing deposits consist of demand deposit and noninterest bearing money market (“MMDA”) account balances. The $131.73 million decrease in noninterest-bearing deposits was due mainly to a $99.65 million or 2.22% decrease in commercial noninterest-bearing deposits and a $32.30 million or 54.40% decrease in official checks. In addition, items in-process decreased $34.53 million. Partially offsetting these decreases in noninterest-bearing deposits was an increase in public noninterest-bearing deposits of $25.59 million or 16.24% and an increase in personal noninterest-bearing deposits of $7.96 million or less than 1%.

Interest-bearing deposits consist of interest-bearing transaction, regular savings, interest-bearing MMDA, and time deposit account balances. Interest-bearing transaction accounts decreased $145.62 million or 2.58% since year-end 2023 as the result of decreases of $57.60 million in personal interest-bearing transaction accounts, $81.28 million in commercial interest-bearing transaction accounts, and $6.74 million in public funds interest-bearing transaction accounts. Regular savings accounts decreased $22.71 million or 1.69% mainly as a result of a $14.63 million decrease in personal savings accounts and a $9.86 million decrease in commercial savings accounts. Interest-bearing MMDAs increased $265.66 million or 4.18%. In particular, personal MMDAs increased $69.61 million while commercial MMDAs and public funds MMDAs increased $175.05 million and $21.00 million, respectively.

Time deposits under $100,000 increased $41.49 million or 3.89% from year-end 2023. This increase in time deposits under $100,000 was the result of a $45.06 million increase in fixed rate Certificates of Deposits (“CDs”) under $100,000. Partially offsetting this increase in deposits under $100,000 was a $3.36 million decrease in CDs under $100,000 obtained through the use of deposit listing services.

Since year-end 2023, time deposits over $100,000 increased $93.34 million or 4.13% as fixed rate CDs increased $109.62 million. Partially offsetting this increase in time deposits over $100,000, were decreases of $5.49 million in CDARS over $100,000, $4.36 million in brokered CDs, and $5.71 million in public funds CDs over $100,000.

Borrowings

Total borrowings at March 31, 2024 decreased $38.04 million or 1.92% since year-end 2023. During the first three months of 2024, short-term borrowings increased $11.63 million or 5.93% due to an increase in securities sold under agreements to repurchase. Long-term borrowings decreased $49.67 million or 2.78% from year-end 2023 due to maturities of advances obtained from the FHLB during the first quarter of 2024.

Net income for the first quarter of 2024 was $86.81 million as compared to earnings of $98.31 million for the first quarter of 2023. Earnings for the first quarter of 2024, as compared to the first quarter of 2023, decreased primarily due to lower net interest income as a result of the impact of higher market interest rates on interest-bearing liabilities. Diluted earnings per share were $0.64 for the first quarter of 2024 and $0.73 for the first quarter of 2023. On a linked-quarter basis, net income for the fourth quarter of 2023 was $79.39 million or $0.59 per diluted share. The fourth quarter of 2023 included $11.99 million of noninterest expense for the FDIC special assessment levied on banking organizations as compared to an additional $1.81 million of noninterest expense for the first quarter of 2024 related to the FDIC’s revised loss estimates to the Deposit Insurance Fund.

United’s annualized return on average assets for the first three months of 2024 was 1.19% and return on average shareholders’ equity was 7.25% as compared to 1.35% and 8.72%, respectively, for the first three months of 2023. On a linked-quarter basis, United’s annualized return on average assets for the fourth quarter of 2024 was 1.08% and return on average shareholders’ equity was 6.70%. For the first three months of 2024, United’s annualized return on average tangible equity, a non-GAAP measure, was 11.98%, as compared to 14.97% for the first three months of 2023. On a linked-quarter basis, United’s annualized return on average tangible equity was 11.27% for the fourth quarter of 2023.

Net interest income for the first quarter of 2024 decreased $11.83 million, or 5.05%, to $222.49 million from net interest income of $234.32 million for the first three months of 2023. The decrease of $11.83 million in net interest income occurred because total interest income increased $39.88 million while total interest expense increased $51.71 million from the first quarter of 2023. Net interest income for the first quarter of 2024 decreased $7.20 million, or 3.14%, from the fourth quarter of 2023. The decrease of $7.20 million in net interest income occurred because total interest income increased $5 thousand while total interest expense increased $7.21 million from the fourth quarter of 2023.

The provision for credit losses was $5.74 million for the first quarter of 2024 as compared to a provision for credit losses of $6.89 million for the first quarter of 2023. The decrease in the provision for credit losses was mainly due to a change in qualitative factors and the impact of reasonable and supportable forecasts of future macroeconomic conditions. On a linked-quarter basis, the provision for credit losses for the first quarter of 2024 declined $1.14 million from $6.88 million for the fourth quarter of 2023 due mainly to less portfolio loan growth as well as a change in the impact of reasonable and supportable forecasts of future macroeconomic conditions in the first quarter of 2024 as compared to the fourth quarter of 2023.

63

Noninterest income was $32.21 million for the first three months of 2024, a decrease of $532 thousand or 1.62% from the first three months of 2023 due mainly to a decrease in mortgage loan servicing income of $1.49 million partially offset by increased fees of $1.07 million from brokerage services. On a linked-quarter basis, noninterest income for the first quarter of 2024 decreased $1.46 million, or 4.34%, from the fourth quarter of 2023. The fourth quarter of 2023 included a $2.66 million gain from the payoff of a fixed rate commercial loan that had an associated interest rate swap derivative. Partially offsetting the decrease in noninterest income was a $907 thousand increase in fees from brokerage services.

Noninterest expense for the first quarter of 2024 was $140.74 million, an increase of $3.32 million or 2.42% from the first quarter of 2023 primarily due to increases in employee compensation and FDIC insurance expense partially offset by a decrease in other noninterest expense. On a linked-quarter basis, noninterest expense for the first quarter of 2024 decreased $11.55 million or 7.58% from the fourth quarter of 2023. This decrease in noninterest expense was driven by decreases in FDIC insurance expense and other noninterest expense partially offset by an increase in employee benefits.

Income taxes decreased $3.04 million or 12.45% for the first three months of 2024 as compared to the first three months of 2023 primarily due to decreased earnings and a slightly lower effective tax rate. On a linked-quarter basis, income taxes decreased $3.41 million or 13.73% for the first quarter of 2024 as compared to the fourth quarter of 2023 due mainly to a lower effective tax rate partially offset by higher earnings. The effective tax rate was 19.78% and 19.92% and for the first quarter of 2024 and 2023, respectively. The effective tax rate was 23.81% for the fourth quarter of 2023.

The following discussion explains in more detail the consolidated results of operations by major category.

Net Interest Income

Net interest income represents the primary component of United’s earnings. It is the difference between interest income from earning assets and interest expense incurred to fund these assets. Net interest income is impacted by changes in the volume and mix of interest-earning assets and interest-bearing liabilities, as well as changes in market interest rates. Such changes, and their impact on net interest income in 2024 and 2023, are presented below.

Net interest income for the first quarter of 2024 was $222.49 million, which was a decrease of $11.83 million or 5.05% from the first quarter of 2023. The $11.83 million decrease in net interest income occurred because total interest income increased $39.88 million while total interest expense increased $51.71 million from the first quarter of 2023. On a linked-quarter basis, net interest income for the first quarter of 2024 decreased $7.20 million, or 3.14%, from the fourth quarter of 2023. The $7.20 million decrease in net interest income occurred because total interest income increased $5 thousand while total interest expense increased $7.21 million from the fourth quarter of 2023.

For the purpose of this remaining discussion, net interest income is presented on a tax-equivalent basis to provide a comparison among all types of interest earning assets. 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.

Tax-equivalent net interest income for the first quarter of 2024 was $223.36 million, which was a decrease of $12.09 million or 5.14% from the first quarter of 2023. The decrease in net interest income and tax-equivalent net interest income was primarily due to higher interest expense driven by deposit rate repricing, an increase in average interest-bearing deposits and a decrease in loan fees partially offset by the impact of rising market interest rates on earning assets, organic loan growth and a decrease in average long-term borrowings. The average cost of funds increased 104 basis points from the first quarter of 2023 to 3.21% driven by an increase in the yield on average interest-bearing deposits of 127 basis points. Average interest-bearing deposits increased $1.48 billion or 9.73% from the first quarter of 2023.

64

Acquired loan accretion income for the first quarter of 2024 decreased $613 thousand from the first quarter of 2023. Loan fees for the first quarter of 2024 decreased $351 thousand from the first quarter of 2023. The yield on average earning assets increased 60 basis points from the first quarter of 2023 to 5.70% driven by an increase in the yield on average net loans of 53 basis points. Average net loans increased $800.47 million, or 3.91%, from the first quarter of 2023. The net interest margin of 3.44% for the first quarter of 2024 was a decrease of 19 basis points from the net interest margin of 3.63% for the first quarter of 2023.

On a linked-quarter basis, tax-equivalent net interest income for the first quarter of 2024 decreased $7.20 million, or 3.12%, from the fourth quarter of 2023. The decrease in net interest income and tax-equivalent net interest income was primarily due to higher interest expense driven by the impact of deposit rate repricing and a decrease in loan fees. The yield on average interest-bearing deposits increased 15 basis points to 3.10% for the first quarter of 2024. Overall, the average cost of funds for the first quarter of 2024 increased 14 basis points from the fourth quarter of 2023. In comparison, the yield on average earning assets for the first quarter of 2024 increased 2 basis points from the fourth quarter of 2023. Loan fees for the first quarter of 2024 decreased $677 thousand from the fourth quarter of 2023. Acquired loan accretion income for the first quarter of 2024 decreased $521 thousand from the fourth quarter of 2023. Average earning assets for the first quarter of 2024 were relatively flat from the fourth quarter of 2023, increasing $211.65 million or less than 1%. Average net loans increased $224.86 million or 1.07% and average short-term investments increased $63.23 million or 7.72% while average investments decreased $76.44 million or 1.90%. The net interest margin of 3.44% for the first quarter of 2024 was a decrease of 11 basis points from the net interest margin of 3.55% for the fourth quarter of 2023.

United’s tax-equivalent net interest income also includes the impact of acquisition accounting fair value adjustments. The following table provides the discount/premium and net accretion impact to tax-equivalent net interest income for the three months ended March 31, 2024, March 31, 2023 and December 31, 2023:

Provision for Credit Losses

The provision for credit losses was $5.74 million for the first quarter of 2024 as compared to a provision for credit losses of $6.89 million for the first quarter of 2023. On a linked-quarter basis, the provision for credit losses for the fourth quarter of 2023 was $6.88 million. United’s provision for credit losses relates to its portfolio of loans and leases, held-to-maturity securities and interest receivable on loans which are discussed in more detail in the following paragraphs.

For the quarter ended March 31, 2024, the provision for loan and lease losses was a $5.74 million as compared to a provision for loan and lease losses of $6.89 million for the quarter ended March 31, 2023. The lower amount of provision expense for the first quarter of 2024 compared to the first quarter of 2023 was mainly due to less credit deterioration expected within the portfolios for 2024 as compared to 2023. Net charge-offs were $2.07 million for the first quarter of 2024 compared to net charge-offs were $1.14 million for the first quarter of 2023. The higher amount of net charge-offs for 2024 as compared to 2023 was primarily due to increased charge-offs within the consumer portfolio. On a linked-quarter basis, the provision for loan and lease losses for the fourth quarter of 2023 was $6.88 million. The decline of $1.14 million for the first quarter of 2024 from the fourth quarter of 2023 was due mainly to a greater amount of recoveries in the first quarter of 2024 compared to fourth quarter of 2023, primarily in the commercial real estate owner-occupied portfolio and other commercial portfolio. Net charge-offs were $2.53 million for the fourth quarter of 2023. Annualized net charge-offs as a percentage of average loans and leases, net of unearned income for the first quarter of 2024 were 0.04% as compared to annualized net charge-offs of 0.02% for the first quarter of 2023 and annualized net charge-offs of 0.05% for the fourth quarter of 2023.

The following table shows a summary of United’s nonperforming assets including nonperforming loans and other real estate owned (“OREO”) at March 31, 2024 and December 31, 2023:

(In thousands)	March 31 2024		December 31 2023
Nonaccrual loans	$	63,053	$	30,919
Loans past due 90 days of more		11,329		14,579
Total nonperforming loans	$	74,382	$	45,498
Other real estate owned		2,670		2,615
Total nonperforming assets	$	77,052	$	48,113

The increase of $32.13 million in nonaccrual loans from December 31, 2023 to March 31, 2024 was due mainly to the transfer to nonaccrual of one significant commercial lending relationship.

United maintains an allowance for loan and lease losses and a reserve for lending-related commitments. The combined allowance for loan losses and reserve for lending-related commitments is considered the allowance for credit losses. At March 31, 2024, the allowance for credit losses was $305.82 million as compared to $303.94 million at December 31, 2023.

At March 31, 2024, the allowance for loan and lease losses was $262.91 million as compared to $259.24 million at December 31, 2023. The slight increase in the allowance for loan and lease losses was primarily driven by increases in the reserves for the commercial real estate, both owner and non-owner occupied, the residential real estate and the other commercial loans segments due to increased outstanding loan balances and increased adjustments resulting from the reasonable and supportable forecast. As a percentage of loans and leases, net of unearned income, the allowance for loan losses was 1.22% at March 31, 2024 and 1.21% at December 31, 2023. The ratio of the allowance for loan and lease losses to nonperforming loans and leases or coverage ratio was 353.45% and 569.78% at March 31, 2024 and December 31, 2023, respectively. The increase in this ratio was due mainly to an increase in nonperforming loans.

68

United continues to evaluate risks which may impact its loan and lease portfolios. Reserves are initially determined based on losses identified from the PD/LGD and Cohort models which utilize the Company’s historical information. Then, any qualitative adjustments are applied to account for the Company’s view of current conditions, the future and other factors.

The first quarter of 2024 qualitative adjustments include analyses of the following:

• Current conditions – United considered the impact of inflation, interest rates, the banking regulatory environment and geopolitical conflict when making determinations related to factor adjustments for the external environment. United also considered portfolio trends related to economic and business conditions, collateral values for dependent loans; past due, nonaccrual and graded loans and leases; and concentrations of credit.

• Reasonable and supportable forecasts – The forecast is determined on a portfolio-by-portfolio basis by relating the correlation of real GDP and the unemployment rate to loss rates to forecasts of those variables. The reasonable and supportable forecast selection is subjective in nature and requires more judgment compared to the other components of the allowance. Assumptions for the economic variables were the following:

• The forecast for real GDP in 2024 increased in the first quarter, from a projection of 1.40% for 2024 at the end of 2023 to 2.10% for 2024 with a slightly smaller increase for 2025, from a projection of 1.80% for 2025 at the end of 2023 to 2.00% for 2025. The unemployment rate remained fairly consistent to the end of 2023 with a steady trend expected throughout 2024 and 2025.

• Greater risk of loss is probable in the office portfolio due to continued hybrid and remote work that may be exacerbated by future economic conditions as well as higher interest rates and cap rates.

• Reversion to historical loss data occurs via a straight-line method during the year following the one-year reasonable and supportable forecast period.

United’s review of the allowance for loan and lease losses at March 31, 2024 produced increased reserves in two of the four loan categories as compared to December 31, 2023. The allowance related to the commercial, financial & agricultural loan pool, consisting of the owner and non-owner occupied commercial real estate and other commercial loan segments, increased $3.99 million due to increased outstanding balances and increased reasonable and supportable forecast adjustments particularly as it pertains to office loans. The residential real estate segment reserve increased $4.79 million due primarily to increased outstanding balances. The real estate construction and development loan segment reserve decreased $4.39 million due to decreased outstanding balances. The consumer loan segment reserve decreased $728 thousand primarily due to a decrease in outstanding balances.

An allowance is established for estimated lifetime losses for loans that are individually assessed. Nonperforming commercial loans and leases are regularly reviewed to identify expected credit losses. A loan is individually assessed for expected credit losses when the loan does not share similar characteristics with other loans in the portfolio. Measuring expected credit losses of a loan requires judgment and estimates, and the eventual outcomes may differ from those estimates. Expected credit losses are measured based upon the present value of expected future cash flows from the loan discounted at the loan’s effective rate or the fair value of collateral if the loan is collateral dependent. When the selected measure is less than the recorded investment in the loan, an expected credit loss has occurred. The allowance for loans and leases that were individually assessed was $18.02 million at March 31, 2024 and $13.15 million at December 31, 2023. In comparison to the prior year-end, this element of the allowance increased $4.87 million due to the downgrade of a commercial real estate non-owner occupied loan.

69

Management believes that the allowance for credit losses of $305.82 million at March 31, 2024 is adequate to provide for expected losses on existing loans and lending-related commitments based on information currently available. United’s loan administration policies are focused on the risk characteristics of the loan portfolio in terms of loan approval and credit quality. The commercial loan portfolio is monitored for possible concentrations of credit in one or more industries. Management has lending limits as a percentage of capital per type of credit concentration in an effort to ensure adequate diversification within the portfolio. Most of United’s commercial loans are secured by real estate located in West Virginia, southeastern Ohio, Pennsylvania, Virginia, Maryland, North Carolina, South Carolina, and the District of Columbia. It is the opinion of management that these commercial loans do not pose any unusual risks and that adequate consideration has been given to these loans in establishing the allowance for credit losses.

The provision for credit losses related to held to maturity securities for the first quarter of 2024 and 2023 was immaterial. The allowance for credit losses related to held to maturity securities was $19 thousand and $17 thousand as of March 31, 2024 and December 31, 2023, respectively. There was no provision for credit losses recorded on available for sale investment securities for the first quarter of 2024 and 2023 and no allowance for credit losses on available for sale investment securities as of March 31, 2024 and December 31, 2023.

Management is not aware of any potential problem loans or leases, trends or uncertainties, which it reasonably expects, will materially impact future operating results, liquidity, or capital resources which have not been disclosed. Additionally, management has disclosed all known material credits, which cause management to have serious doubts as to the ability of such borrowers to comply with the loan repayment schedules.

Other Income

Other income consists of all revenues, which are not included in interest and fee income related to earning assets. Noninterest income has been and will continue to be an important factor for improving United’s profitability. Recognizing the importance, management continues to evaluate areas where noninterest income can be enhanced.

Noninterest income for the first quarter of 2024 was $32.21 million, a decrease of $532 thousand or 1.62% from the first quarter of 2023 driven by decreases in mortgage loan servicing income and mortgage banking income partially offset by an increase in fees from brokerage services and lower net losses on investment securities transactions.

Mortgage loan servicing income for the first quarter of 2024 decreased $1.49 million or 65.33% from the first quarter of 2023. The decrease in mortgage loan servicing income was due to lower mortgage servicing rights (“MSRs”) balances after the sale of MSRs during the second quarter of 2023.

Income from mortgage banking activities totaled $5.30 million for the first quarter of 2024 compared to $6.38 million for the first quarter of 2023. The decrease of $1.09 million or 17.01% for the first quarter of 2024 was mainly due to a decrease in the fair value of loans held for sale. Mortgage loan sales were $188.74 million in the first quarter of 2024 as compared to $166.51 million in the first quarter of 2023. Mortgage loans originated for sale were $176.91 million for the first quarter of 2024 as compared to $177.81 million for the first quarter of 2023.

Fees from brokerage services for the first quarter of 2024 increased $1.07 million or 25.40% from the first quarter of 2023. The increase was primarily due to higher volume.

United recorded a net loss on investment securities of $99 thousand for the first quarter of 2024 as compared to a net loss on investment securities of $405 thousand for the first quarter of 2023 driven primarily by a net loss of $420 thousand on the sale of AFS securities in last year’s first quarter.

On a linked-quarter basis, noninterest income for the first quarter of 2024 decreased $1.46 million, or 4.34%, from the fourth quarter of 2023 driven by a decrease of $3.00 million in other noninterest income. The fourth quarter of 2023 included a $2.66 million gain from the payoff of a fixed rate commercial loan that had an associated interest rate swap derivative. Partially offsetting the decrease in noninterest income was a $907 thousand increase in fees from brokerage services primarily due to higher volume.

70

Other Expenses

Just as management continues to evaluate areas where noninterest income can be enhanced, it strives to improve the efficiency of its operations to reduce costs. Other expenses include all items of expense other than interest expense, the provision for credit losses, and income taxes. Noninterest expense for the first quarter of 2024 was $140.74 million, which was an increase of $3.32 million or 2.42% from the first quarter of 2023.

Employee compensation for the first quarter of 2024 increased $3.88 million or 7.00% when compared to the first quarter of 2023. The increase in employee compensation was driven by higher employee incentives, commissions, base salaries and employee severance.

Employee benefits expense for the first quarter of 2024 increased $1.24 million or 9.20% from the first quarter of 2023. This increase was primarily due to higher amounts of expense for postretirement benefits.

Mortgage servicing and impairment expense decreased $869 thousand or 46.13% due to a lower amount of loans serviced.

FDIC expense increased $1.87 million or 40.72% from the first quarter of 2023 due to an additional special assessment accrual of $1.81 million resulting from the FDIC’s revised loss estimates to the Deposit Insurance Fund.

Other expense for the first quarter of 2024 decreased $2.69 million or 7.77% from the first quarter of 2023. Within other expenses, the most significant decrease was the expense for the reserve for unfunded commitments of $4.39 million due to lower amount of outstanding loan commitments. Partially offsetting this decrease was an increase in the amortization of investment tax credits of $950 thousand.

On a linked-quarter basis, noninterest expense for the first quarter of 2024 decreased $11.55 million, or 7.58%, from the fourth quarter of 2023. This decrease in noninterest expense was driven by decreases in FDIC insurance expense of $10.17 million and other noninterest expense of $8.02 million partially offset by an increase in employee benefits of $4.90 million and employee compensation of $1.46 million. The fourth quarter of 2023 included $11.99 million of expense for the FDIC special assessment. The first quarter of 2024 included an additional expense of $1.81 million related to the FDIC special assessment stemming from the FDIC’s revised loss estimates. The decrease of $8.02 million in other noninterest expense was driven primarily by decreases of $2.73 million in the expense for the reserve for unfunded commitments, $1.23 million of expense related to community development lending programs and $1.22 million of amortization for investment tax credits. Additionally, other noninterest expense for the fourth quarter of 2023 included $1.28 million related to trade name intangible impairments. The decrease in the expense for the reserve for unfunded loan commitments was driven by a decrease in the outstanding balance of loan commitments. The increase in employee benefits was primarily driven by higher postretirement benefit costs and higher Federal Insurance Contributions Act (“FICA”) costs. Employee compensation for the first quarter of 2024 increased due mainly to higher amount of base salaries and approximately $240 thousand of severance expense associated with the mortgage delivery channel consolidation.

Income Taxes

For the first quarter of 2024, income tax expense was $21.41 million as compared to $24.45 million for the first quarter of 2023. The decrease of $3.04 million was primarily due to decreased earnings and lower effective tax rate. On a linked-quarter basis, income tax expense decreased $3.41 million primarily due to a lower effective tax rate partially offset by higher earnings. United’s effective tax rate was 19.78% for the first quarter of 2024, 19.92% for the first quarter of 2023 and 23.81% for the fourth quarter of 2023.

71

Liquidity and Capital Resources

In the opinion of management, United maintains liquidity that is sufficient to satisfy its depositors’ requirements and the credit needs of its customers. Like all banks, United depends upon its ability to renew maturing deposits and other liabilities on a daily basis and to acquire new funds in a variety of markets. A significant source of funds available to United is “core deposits”. Core deposits include certain demand deposits, statement and special savings and NOW accounts. These deposits are relatively stable, and they are the lowest cost source of funds available to United. Short-term borrowings have also been a significant source of funds. These include federal funds purchased and securities sold under agreements to repurchase as well as advances from the FHLB. Repurchase agreements represent funds which are obtained as the result of a competitive bidding process.

Liquid assets are cash and those items readily convertible to cash. All banks must maintain sufficient balances of cash and near-cash items to meet the day-to-day demands of customers and United’s cash needs. Other than cash and due from banks, the available for sale securities portfolio and maturing loans are the primary sources of liquidity.

The goal of liquidity management is to ensure the ability to access funding which enables United to efficiently satisfy the cash flow requirements of depositors and borrowers and meet United’s cash needs. Liquidity is managed by monitoring funds’ availability from a number of primary sources. Substantial funding is available from cash and cash equivalents, unused short-term borrowing and a geographically dispersed network of branches providing access to a diversified and substantial retail deposit market.

Short-term needs can be met through a wide array of outside sources such as correspondent and downstream correspondent federal funds and utilization of Federal Home Loan Bank advances.

Other sources of liquidity available to United to provide long-term as well as short-term funding alternatives, in addition to FHLB advances, are long-term certificates of deposit, lines of credit, borrowings that are secured by bank premises or stock of United’s subsidiaries and issuances of trust preferred securities. In the normal course of business, United through its Asset Liability Committee evaluates these as well as other alternative funding strategies that may be utilized to meet short-term and long-term funding needs.

During the first quarter of 2024, United increased its interest-bearing deposit balance at the FRB by $135.62 million to $1.38 billion. The change in the balance at the FRB was mostly the result of a $100.43 million increase in total deposits and $168.36 million of net sales, maturities, and paydowns in the available for sale debt securities portfolio partially offset by a $50.07 million decrease in FHLB advances.

For the three months ended March 31, 2024, cash of $124.37 million was provided by operating activities due mainly to net income of $86.81 million. In addition, proceeds from the sale of mortgage loans in the secondary market exceeded originations by $17.14 million. Net cash of $2.43 million was used in investing activities which was primarily due to loan growth of $160.68 million and net purchases of $4.71 million in bank premises and equipment over sales proceeds mostly offset by $162.81 million of net proceeds from sales of investment securities over purchases. During the first three months of 2024, net cash of $11.77 million was provided by financing activities due primarily to growth of $100.60 million in deposits partially offset by cash dividends paid of $50.14 million and the net repayment of $50.00 million in FHLB borrowings during the quarter. The net effect of the cash flow activities was an increase in cash and cash equivalents of $133.70 million for the first three months of 2024.

At March 31, 2024, United had an unused borrowing amount at the FHLB of approximately $7.00 billion subject to delivery of collateral after certain trigger points, $2.86 billion without the delivery of additional collateral. United has various unused lines of credit available from certain of its correspondent banks in the aggregate amount of $280 million, all of which was available at March 31, 2024. United also has a $20 million unsecured, revolving line of credit with an unrelated financial institution to provide for general liquidity needs, all of which was available at March 31, 2024. At March 31, 2024, United’s borrowing capacity for the FRB Discount Window was $2.53 billion. United did not have any borrowings from the FRB’s Discount Window, or its new Bank Term Funding Program, during the first quarter of 2024.

72

United anticipates it can meet its obligations over the next 12 months and has no material commitments for capital expenditures. United also has lines of credit available. See Notes 9 and 10 to the accompanying unaudited Notes to Consolidated Financial Statements for more details regarding the amounts available to United under lines of credit.

The Asset Liability Committee monitors liquidity to ascertain that a liquidity position within certain prescribed parameters is maintained. No changes are anticipated in the policies of United’s Asset Liability Committee.

United’s capital position is financially sound. United seeks to maintain a proper relationship between capital and total assets to support growth and sustain earnings. United has historically generated attractive returns on shareholders’ equity. United is well-capitalized based upon regulatory guidelines. United’s risk-based capital ratio is 15.55% at March 31, 2024 while its Common Equity Tier 1 capital, Tier 1 capital and leverage ratios are 13.22%, 13.22% and 11.41%, respectively. The March 31, 2024 ratios reflects United’s election of a five-year transition provision, allowed by the Federal Reserve Board and other federal banking agencies in response to the COVID-19 pandemic, to delay for two years the full impact of CECL on regulatory capital, followed by a three-year transition period. The regulatory requirements for a well-capitalized financial institution are a risk-based capital ratio of 10.0%, a Common Equity Tier 1 capital ratio of 6.5%, a Tier 1 capital ratio of 8.0% and a leverage ratio of 5.0%.

Total shareholders’ equity was $4.81 billion at March 31, 2024, which was relatively flat from December 31, 2023, increasing $36.20 million or less than 1%. This increase is primarily due to increases of $36.60 million in retained earnings (net income less dividends declared).

United’s equity to assets ratio was 16.01% at March 31, 2024 as compared to 15.94% at December 31, 2023. The primary capital ratio, capital and reserves to total assets and reserves, was 16.86% at March 31, 2024 as compared to 16.79% at December 31, 2023. United’s average equity to average asset ratio was 16.36% for the first quarter of 2024 as compared to 15.49% the first quarter of 2023. All of these financial measurements reflect a financially sound position.

During the first quarter of 2024, United’s Board of Directors declared a cash dividend of $0.37 per share. Total cash dividends declared were $50.21 million for the first quarter of 2024 which was an increase of $1.49 million or 3.07% from dividends declared of $48.72 million for the first quarter of 2023.

Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The objective of United’s Asset Liability Management function is to maintain consistent growth in net interest income within United’s policy guidelines. This objective is accomplished through the management of balance sheet liquidity and interest rate risk exposures due to changes in economic conditions, interest rate levels and customer preferences.

Interest Rate Risk

Management considers interest rate risk to be United’s most significant market risk. Interest rate risk is the exposure to adverse changes in United’s net interest income as a result of changes in interest rates. United’s earnings are largely dependent on the effective management of interest rate risk.

Management of interest rate risk focuses on maintaining consistent growth in net interest income within Board-approved policy limits. United’s Asset/Liability Management Committee (“ALCO”), which includes senior management representatives and reports to the Board, monitors and manages interest rate risk to maintain an acceptable level of change to net interest income as a result of changes in interest rates. Policy established for interest rate risk is stated in terms of the change in net interest income over a one-year and two-year horizon given an immediate and sustained increase or decrease in interest rates. The current limits approved by the Board are structured on a staged basis with each stage requiring specific actions.

73

United employs a variety of measurement techniques to identify and manage its exposure to changing interest rates. One such technique utilizes an earnings simulation model to analyze the sensitivity of net interest income to movements in interest rates. The model is based on actual cash flows and repricing characteristics for on and off-balance sheet instruments and incorporates market-based assumptions regarding the impact of changing interest rates on the prepayment rate of certain assets and liabilities. The model also includes executive management projections for activity levels in product lines offered by United. Assumptions based on the historical behavior of deposit rates and balances in relation to changes in interest rates are also incorporated into the model. Rate scenarios could involve parallel or nonparallel shifts in the yield curve, depending on historical, current, and expected conditions, as well as the need to capture any material effects of explicit or embedded options. These assumptions are inherently uncertain and, as a result, the model cannot precisely measure net interest income or precisely predict the impact of fluctuations in interest rates on net interest income. Actual results will differ from simulated results due to timing, magnitude and frequency of interest rate changes as well as changes in market conditions and management’s strategies.

Interest sensitive assets and liabilities are defined as those assets or liabilities that mature or are repriced within a designated time frame. The principal function of managing interest rate risk is to maintain an appropriate relationship between those assets and liabilities that are sensitive to changing market interest rates. The difference between rate sensitive assets and rate sensitive liabilities for specified periods of time is known as the “GAP.” Earnings-simulation analysis captures not only the potential of these interest sensitive assets and liabilities to mature or reprice, but also the probability that they will do so. Moreover, earnings-simulation analysis considers the relative sensitivities of these balance sheet items and projects their behavior over an extended period of time. United closely monitors the sensitivity of its assets and liabilities on an on-going basis and projects the effect of various interest rate changes on its net interest margin.

The following table shows United’s estimated earnings sensitivity profile as of March 31, 2024 and December 31, 2023:

Change in Interest Rates (basis points)	Percentage Change in Net Interest Income
	March 31, 2024	December 31, 2023
+200	(0.62%)	(0.28%)
+100	0.07%	0.24%
-100	2.82%	2.66%
-200	4.31%	4.35%

At March 31, 2024, given an immediate, sustained 100 basis point upward shock to the yield curve used in the simulation model, net interest income for United is estimated to increase by 0.07% over one year as compared to an increase by 0.24% at December 31, 2023. A 200 basis point immediate, sustained upward shock in the yield curve would decrease net interest income by an estimated 0.62% over one year as of March 31, 2024, as compared to a decrease of 0.28% as of December 31, 2023. A 100 basis point immediate, sustained downward shock in the yield curve would increase net interest income by an estimated 2.82% over one year as of March 31, 2024 as compared to an increase of 2.66%, over one year as of December 31, 2023. A 200 basis point immediate, sustained downward shock in the yield curve would increase net interest income by an estimated 4.31% over one year as of March 31, 2024 as compared to an increase of 4.35% over one year as of December 31, 2023.

In addition to the one year earnings sensitivity analysis, a two-year analysis is also performed. Compared to the one year analysis, United is projected to show improved performance in year two within the upward rate shock scenarios. Given an immediate, sustained 100 basis point upward shock to the yield curve used in the simulation model, net interest income for United is estimated to increase by 1.94% in year two as of March 31, 2024. A 200 basis point immediate, sustained upward shock in the yield curve would increase net interest income by an estimated 2.80% in year two as of March 31, 2024. A 100 basis point immediate, sustained downward shock in the yield curve would increase net interest income by an estimated 0.46% in year two as of March 31, 2024. A 200 basis point immediate, sustained downward shock in the yield curve would decrease net interest income by an estimated 0.76% in year two as of March 31, 2024.

74

While it is unlikely market rates would immediately move 100 or 200 basis points upward or downward on a sustained basis, this is another tool used by management and the Board to gauge interest rate risk. All of these estimated changes in net interest income are and were within the policy guidelines established by the Board.

To further aid in interest rate management, United’s subsidiary bank is a member of the Federal Home Loan Bank (“FHLB”). The use of FHLB advances provides United with a low risk means of matching maturities of earning assets and interest-bearing funds to achieve a desired interest rate spread over the life of the earning assets. In addition, United uses credit with large regional banks and trust preferred securities to provide funding.

As part of its interest rate risk management strategy, United may use derivative instruments to protect against adverse price or interest rate movements on the value of certain assets or liabilities and on future cash flows. These derivatives commonly consist of interest rate swaps, caps, floors, collars, futures, forward contracts, written and purchased options. Interest rate swaps obligate two parties to exchange one or more payments generally calculated with reference to a fixed or variable rate of interest applied to the notional amount. United accounts for its derivative activities in accordance with the provisions of ASC Topic 815, “Derivatives and Hedging.”

Extension Risk

A key feature of most mortgage loans is the ability of the borrower to repay principal earlier than scheduled. This is called a prepayment. Prepayments arise primarily due to sale of the underlying property, refinancing, or foreclosure. In general, declining interest rates tend to increase prepayments, and rising interest rates tend to slow prepayments. Like other fixed-income securities, when interest rates rise, the value of mortgage- related securities generally declines. The rate of prepayments on underlying mortgages will affect the price and volatility of mortgage-related securities and may shorten or extend the effective maturity of the security beyond what was anticipated at the time of purchase. If interest rates rise, United’s holdings of mortgage-related securities may experience reduced returns if the borrowers of the underlying mortgages pay off their mortgages later than anticipated. This is generally referred to as extension risk.

At March 31, 2024, United’s mortgage related securities portfolio had an amortized cost of $1.8 billion, of which approximately $745.1 million or 42% were fixed rate collateralized mortgage obligations (“CMOs”). These fixed rate CMOs consisted primarily of planned amortization class (“PACs”), sequential-pay and accretion directed (“VADMs”) bonds having an average life of approximately 5.7 years and a weighted average yield of 2.09%, under current projected prepayment assumptions. These securities are expected to have moderate extension risk in a rising rate environment. Current models show that immediate, sustained upward shock of 300 basis points, the average life of these securities would only extend to 6.7 years. The projected price decline of the fixed rate CMO portfolio in rates up 300 basis points would be 15.9%, or less than the price decline of a 7- year treasury note. By comparison, the price decline of a 30-year 5.5% current coupon mortgage backed security (“MBS”) in rates higher by 300 basis points would be approximately 12.2%.

United had approximately $487.9 million in fixed rate commercial mortgage backed securities (“CMBS”) with a projected yield of 1.94% and a projected average life of 4.5 years on March 31, 2024. This portfolio consisted primarily of Freddie Mac Multifamily K securities and Fannie Mae Delegated Underwriting and Servicing (“DUS”) securities with a weighted average maturity (“WAM”) of 8.3 years.

United had approximately $22.9 million in 15-year mortgage backed securities with a projected yield of 1.98% and a projected average life of 4.6 years as of March 31, 2024. This portfolio consisted of seasoned 15-year mortgage paper with a weighted average loan age (“WALA”) of 4.2 years and a WAM of 11.1 years.

75

United had approximately $318.9 million in 20-year mortgage backed securities with a projected yield of 1.82% and a projected average life of 6.7 years on March 31, 2024. This portfolio consisted of seasoned 20-year mortgage paper with a WALA of 3 years and a WAM of 16.8 years.

United had approximately $151.3 million in 30-year mortgage backed securities with a projected yield of 2.65% and a projected average life of 7.8 years on March 31, 2024. This portfolio consisted of seasoned 30-year mortgage paper with a WALA of 4.6 years and a WAM of 23.7 years.

The remaining 3% of the mortgage related securities portfolio on March 31, 2024, included floating rate CMO, CMBS, and mortgage backed securities.

Item 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

As of March 31, 2024, an evaluation was performed under the supervision of and with the participation of United’s management, including the Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), of the effectiveness of the design and operation of United’s disclosure controls and procedures. Based on that evaluation, United’s management, including the CEO and CFO, concluded that United’s disclosure controls and procedures as of March 31, 2024 were effective in ensuring that information required to be disclosed in the Quarterly Report on Form 10-Q was recorded, processed, summarized and reported within the time period required by the Securities and Exchange Commission’s rules and forms.

Limitations on the Effectiveness of Controls

United’s management, including the CEO and CFO, does not expect that United’s disclosure controls and internal controls will prevent all errors and fraud. While United’s disclosure controls and procedures are designed to provide reasonable assurance of achieving their objective, a control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls.

Changes in Internal Controls

There have been no changes in United’s internal control over financial reporting (as defined in Rules 13a-15(e) and 15d-15(f) under the Exchange Act) that occurred during the quarter ended March 31, 2024, or in other factors that have materially affected or are reasonably likely to materially affect United’s internal control over financial reporting.

76

PART II - OTHER INFORMATION

Item 1. LEGAL PROCEEDINGS

United and its subsidiaries are currently involved in various legal proceedings in the normal course of business.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying unaudited consolidated interim financial statements of United Bankshares, Inc. and Subsidiaries (“United” or “the Company”) have been prepared in accordance with accounting principles for interim financial information generally accepted in the United States (“GAAP”) and with the instructions for Form 10-Q and Article 10 of Regulation S-X. Accordingly, the financial statements do not contain all of the information and footnotes required by accounting principles generally accepted in the United States. In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. The financial statements presented as of March 31, 2024 and 2023 and for the three-month periods then ended have not been audited. The consolidated balance sheet as of December 31, 2023 has been extracted from the audited financial statements included in United’s 2023 Annual Report to Shareholders. The Notes to Consolidated Financial Statements appearing in United’s 2023 Annual Report on Form 10-K, which includes descriptions of significant accounting policies, should be read in conjunction with these interim financial statements. In the opinion of management, any adjustments necessary for a fair presentation of financial position and results of operations for the interim periods have been made. Such adjustments are of a normal and recurring nature.

The accompanying consolidated interim financial statements include the accounts of United and its wholly owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in the consolidated financial statements. Information is presented in these notes to the unaudited consolidated interim financial statements with dollars expressed in thousands, except per share or unless otherwise noted.

Operating and Reporting Segments

As of March 31, 2024, United’s business activities are confined to one operating segment, United Bank, and one reportable segment, community banking. As a community banking entity, United, through United Bank, offers a full range of products and services through various delivery channels. Included among the banking products and services offered are the acceptance of deposits in checking, savings, time and money market accounts; the making and servicing of personal, credit card, commercial, and floor plan loans; and the making of construction and real estate loans as well as the origination and sale of residential mortgages in the secondary market. Also offered are trust and brokerage services, safe deposit boxes, and wire transfers. United’s chief operating decision maker regularly reviews the operating results of United Bank in order to assess performance and make decisions about resource allocation. Previously, United had three operating segments: United Bank, George Mason Mortgage, LLC (“George Mason”) and Crescent Mortgage Company (“Crescent”), and two reporting segments: community banking and mortgage banking. However, during the first quarter of 2024, United consolidated the mortgage origination and sales business of George Mason and Crescent with that of United Bank. United previously exited the third-party origination (“TPO”) business during the fourth quarter of 2023.

New Accounting Standards

In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-09, “Improvements to Income Tax Disclosures.” ASU 2023-09 enhances annual income tax disclosures by requiring (1) consistent categories and greater disaggregation of information in the rate reconciliation and (2) income taxes paid disaggregated by jurisdiction. ASU 2023-09 also includes certain other amendments to improve the effectiveness of income tax disclosures. ASU 2023-09 is effective for public business entities for annual periods beginning after December 15, 2024. For entities other than public business entities, the amendments are effective for annual periods beginning after December 15, 2025. Entities are permitted to early adopt the standard for annual financial statements that have not yet been issued or made available for issuance. The adoption of ASU 2023-09 is not expected to have an impact on the Company’s financial condition or results of operations but could change certain disclosures in United’s SEC filings.

In November 2023, the FASB issued ASU 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures.” The amendments in ASU 2023-07 improve reportable segment disclosure requirements, mainly through enhanced disclosures about significant segment expenses. In addition, the amendments enhance interim disclosure requirements, clarify circumstances in which an entity can disclose multiple segment measures of profit or loss, provide new segment disclosure requirements for entities with a single reportable segment, and contain other disclosure requirements. The purpose of the amendments will enable investors to better understand an entity’s overall performance and assess potential future cash flows. ASU No. 2023-07 is effective for public business entities for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption of the amendment is permitted. The adoption of ASU 2023-07 is not expected to have an impact on the Company’s financial condition or results of operations but could change certain disclosures in United’s SEC filings starting with its 2024 Annual Report on Form 10-K.

In October 2023, the FASB issued ASU 2023-06, “Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative,” which adopts certain disclosure requirements referred by the SEC. For entities subject to the SEC’s existing disclosure requirements and for entities required to file or furnish financial statements with or to the SEC in preparation for the sale of or for purposes of issuing securities that are not subject to contractual restrictions on transfer, the effective date for each amendment will be the date on which the SEC’s removal of that related disclosure from Regulation S-X or Regulation S-K becomes effective, with early adoption prohibited. For all other entities, the amendments will be effective two years later. The adoption of ASU 2023-06 is not expected to have an impact on the Company’s financial condition or results of operations but could change certain disclosures in United’s SEC filings.

In August 2023, the FASB issued ASU 2023-05, “Business Combinations – Joint Venture Formations (Subtopic 805-60).” ASU 2023-05 requires a joint venture to apply a new basis of accounting at its formation date by valuing the net assets contributed at fair value for both business and asset transactions. The value of the net assets in total is then allocated to individual assets and liabilities by applying Topic 805 with certain exceptions. ASU 2023-05 requires certain disclosures to aid the user of the financial statements in understanding the implications of the joint venture formation. ASU 2023-05 is effective for joint venture formations with a formation date on or after January 1, 2025. The adoption of ASU 2023-05 is not expected to have an impact on the Company’s financial condition or results of operations.

In July 2023, the FASB issued ASU No. 2023-03, “Presentation of Financial Statements (Topic 205), Income Statement—Reporting Comprehensive Income (Topic 220), Distinguishing Liabilities from Equity (Topic 480), Equity (Topic 505), and Compensation—Stock Compensation (Topic 718): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 120, SEC Staff Announcement at the March 24, 2022 EITF Meeting, and Staff Accounting Bulletin Topic 6.B, Accounting Series Release 280—General Revision of Regulation S-X: Income or Loss Applicable to Common Stock.” ASU 2023-03 amends the ASC for SEC updates pursuant to SEC Staff Accounting Bulletin No. 120; SEC Staff Announcement at the March 24, 2022 Emerging Issues Task Force (“EITF”) Meeting; and Staff Accounting Bulletin Topic 6.B, Accounting Series Release 280 - General Revision of Regulation S-X: Income or Loss Applicable to Common Stock. These updates were immediately effective and did not have a significant impact on the Company’s financial statements.

In March 2023, the FASB issued Accounting ASU 2023-02, “Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method.” ASU 2023-02 permits reporting entities to elect to account for their tax equity investments, regardless of the tax credit program from which the income tax credits are received, using the proportional amortization method if certain conditions are met. The amendments in this ASU apply to all reporting entities that hold

tax equity investments that meet the conditions for and elect to account for them using the proportional amortization method or an investment in a low income housing tax credit (“LIHTC”) structure through a limited liability entity that is not accounted for using the proportional amortization method and to which certain LIHTC-specific guidance removed from Subtopic 323-740 has been applied. Additionally, the disclosure requirements apply to investments that generate income tax credits and other income tax benefits from a tax credit program for which the entity has elected to apply the proportional amortization method (including investments within that elected program that do not meet the conditions to apply the proportional amortization method). ASU 2023-02 was effective for United on January 1, 2024. The amendments in this update must be applied on either a modified retrospective or a retrospective basis except for LIHTC investments not accounted for using the proportional amortization method. At January 1, 2024, United chose not to elect to account for its tax equity investments using the proportional amortization method.

In December 2022, the FASB issued ASU 2022-06, “Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848.” ASU 2022-06 extends the period of time financial statement preparers can utilize the reference rate reform relief guidance. In 2020, the FASB issued ASU 2020-04 to provide temporary, optional expedients related to the accounting for contract modifications and hedging transactions as a result of the global markets’ anticipated transition away from the use of LIBOR and other interbank offered rates to alternative reference rates. At the time ASU 2020-04 was issued, the United Kingdom’s Financial Conduct Authority (“FCA”) had established the intent that it would no longer be necessary to persuade, or compel, banks to submit to LIBOR after December 31, 2021. As a result, the sunset provision was set for December 31, 2022; 12 months after the expected cessation date of all currencies and tenors of LIBOR. In March 2021, the FCA announced that the intended cessation date of LIBOR in the United States would be June 30, 2023, which has now taken effect as intended. Accordingly, ASU 2022-06 defers the expiration date of ASU 848 to December 31, 2024. United implemented a comprehensive project plan to execute the transition of its LIBOR-based financial instruments to alternative reference rates. United utilized the Secured Overnight Financing Rate (“SOFR”) and Prime as the preferred alternatives to LIBOR.

In June 2022, the FASB issued ASU 2022-03, “Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions.” ASU 2022-03 clarifies that a contractual restriction on the sale of an equity security is not considered part of the unit of account of the equity security and, therefore, is not considered in measuring fair value. ASU 2022-03 also clarifies that an entity cannot, as a separate unit of account, recognize and measure a contractual sale restriction and requires certain new disclosures for equity securities subject to contractual sale restrictions. ASU 2022-03 was effective for United on January 1, 2024. The adoption of ASU 2022-03 did not have a material impact on the Company’s financial condition or results of operations.

For the adoption of ASC Topic 326, “Financial Instruments—Credit Losses,” United made a policy election to exclude accrued interest from the amortized cost basis of available-for-sale debt securities and report accrued interest separately in “Accrued interest receivable” in the consolidated balance sheets. Available-for-sale debt securities are placed on non-accrual status when we no longer expect to receive all contractual amounts due, which is generally at 90 days past due. Accrued interest receivable is reversed against interest income when a security is placed on non-accrual status. Accordingly, United does not currently recognize an allowance for credit loss against accrued interest receivable on available-for-sale debt securities. The table above excludes accrued interest receivable of $19,963 and $20,878 at March 31, 2024 and December 31, 2023, respectively, that is recorded in “Accrued interest receivable.”

The following is a summary of securities available for sale which were in an unrealized loss position at March 31, 2024 and December 31, 2023.

The following table shows the proceeds from maturities, sales and calls of available for sale securities and the gross realized gains and losses on sales and calls of those securities that have been included in earnings as a result of any sales and calls. Gains or losses on sales and calls of available for sale securities were recognized by the specific identification method.

At March 31, 2024, gross unrealized losses on available for sale securities were $366,788 on 1,071 securities of a total portfolio of 1,124 available for sale securities. Securities with the most significant gross unrealized losses at March 31, 2024 consisted primarily of agency residential mortgage-backed securities, state and political subdivision securities, agency commercial mortgage-backed securities and other corporate securities.

In determining whether or not a security is impaired, management considered the severity of the loss in conjunction with United’s positive intent and the more likely than not ability to hold these securities to recovery of their cost basis or maturity. Generally, the significant amount of gross unrealized losses on available for sale securities at March 31, 2024 was the result of rising interest rates.

State and political subdivisions

United’s state and political subdivisions portfolio relates to securities issued by various municipalities located throughout the United States. The total amortized cost of available for sale state and political subdivision securities was $611,240 at March 31, 2024. As of March 31, 2024, approximately 48% of the portfolio was supported by the general obligation of the issuing municipality, which allows for the securities to be repaid by any means available to the municipality. The majority of the portfolio was rated AA or higher, and no securities within the portfolio were rated below investment grade as of March 31, 2024. In addition to monitoring the credit ratings of these securities, management also evaluates the financial performance of the underlying issuers on an ongoing basis. Based upon management’s analysis and judgment, it was determined that none of the state and political subdivision securities had credit losses at March 31, 2024.

Mortgage-backed securities

The fair value of mortgage-backed securities is affected by changes in interest rates and prepayment speeds. When interest rates decline, prepayment speeds generally accelerate due to homeowners refinancing their mortgages at lower interest rates. This may result in the proceeds being reinvested at lower interest rates. Rising interest rates may decrease the assumed prepayment speed. Slower prepayment speeds may extend the maturity of the security beyond its estimated maturity. Therefore, investors may not be able to invest at current higher market rates due to the extended expected maturity of the security. United had a net unrealized loss of $239,195 on mortgage-backed securities at March 31, 2024. Below is a detailed discussion of mortgage-backed securities by type.

United’s agency mortgage-backed securities portfolio relates to securities issued by Fannie Mae, Freddie Mac, and Ginnie Mae. The total amortized cost of available for sale agency mortgage-backed securities was $1,691,373 at March 31, 2024. Of the $1,691,373 amount, $507,889 was related to agency commercial mortgage-backed securities and $1,183,484 was related to agency residential mortgage-backed securities. Each of the agency mortgage-backed securities provides a guarantee of full and timely payments of principal and interest by the issuing agency. Based upon management’s analysis and judgment, it was determined that none of the agency mortgage-backed securities had credit losses at March 31, 2024.

United’s non-agency residential mortgage-backed securities portfolio relates to securities of various private label issuers. The total amortized cost of available for sale non-agency residential mortgage-backed securities was $83,698 at March 31, 2024. Of the $83,698, 100% was rated AAA. Based upon management’s analysis and judgment, it was determined that none of the non-agency residential mortgage-backed securities had credit losses at March 31, 2024.

Asset-backed securities

As of March 31, 2024, United’s asset-backed securities portfolio had a total amortized cost balance of $837,064. 100% of the portfolio was investment grade rated as of March 31, 2024. Approximately 24% of the portfolio relates to securities that are backed by Federal Family Education Loan Program (“FFELP”) student loan collateral which includes a minimum of a 97% government repayment guaranty, as well as additional credit support and subordination in excess of the government guaranteed portion. Approximately 76% of the portfolio relates to collateralized loan obligation securities that are all AAA rated. Upon reviewing this portfolio as of March 31, 2024, it was determined that none of the asset-backed securities had credit losses.

Single issue trust preferred securities

The majority of United’s single issue trust preferred portfolio consists of obligations from large cap banks (i.e. banks with market capitalization in excess of $10 billion). All single issue trust preferred securities are currently receiving interest payments. The amortized cost of available for sale single issue trust preferred securities as of March 31, 2024 consisted of $7,477 in investment grade bonds, $3,109 in split rated bonds, and $5,804 in unrated bonds. Management reviews each issuer’s current and projected earnings trends, asset quality, capitalization levels, and other key factors. Upon completing the review for the first quarter of 2024, it was determined that none of the single issue trust preferred securities had credit losses.

Other corporate securities

As of March 31, 2024, United’s other corporate securities portfolio had a total amortized cost balance of $301,199. The majority of the portfolio consisted of debt issuances of corporations representing a variety of industries, including financial institutions. Of the $301,199, 96% had at least one rating above investment grade, 1% were below investment grade rated, and 3% were unrated. For other corporate securities, management has evaluated the near-term prospects of the investment in relation to the severity of any unrealized loss. Based upon management’s analysis and judgment, it was determined that none of the other corporate securities had credit losses at March 31, 2024.

The amortized cost and estimated fair value of securities available for sale at March 31, 2024 and December 31, 2023 by contractual maturity are shown as follows. Expected maturities may differ from contractual maturities because the issuers may have the right to call or prepay obligations without penalties.

Equity securities at fair value

Equity securities consist mainly of mutual funds of Community Reinvestment Act (“CRA”) qualified investments and equity securities within a rabbi trust for the payment of benefits under a deferred compensation plan for certain key officers of United and its subsidiaries. The fair value of United’s equity securities was $8,762 at March 31, 2024 and $8,945 at December 31, 2023.

Other investment securities

During the first quarter of 2024, United evaluated all of its cost method investments to determine if certain events or changes in circumstances during the first quarter of 2024 had a significant adverse effect on the recorded value of any of its cost method securities. United determined that there was no individual security that experienced an adverse event during the first quarter. There were no other events or changes in circumstances during the first quarter which would have an adverse effect on the recorded fair value of its cost method securities.

The carrying value of securities pledged to secure public deposits, securities sold under agreements to repurchase, and for other purposes as required or permitted by law, approximated $2,279,895 and $2,307,591 at March 31, 2024 and December 31, 2023, respectively.

Credit Quality

4. CREDIT QUALITY

Management monitors the credit quality of its loans and leases on an ongoing basis. Measurement of delinquency and past due status are based on the contractual terms of each loan. United considers a loan to be past due when it is 30 days or more past its contractual payment due date.

For all loan classes, past due loans and leases are reviewed on a monthly basis to identify loans and leases for nonaccrual status. Generally, when collection in full of the principal and interest is jeopardized, the loan is placed on nonaccrual status. The accrual of interest income on commercial and most consumer loans generally is discontinued when a loan becomes 90 to 120 days past due as to principal or interest. However, regardless of delinquency status, if a loan is fully secured and in the process of collection and resolution of collection is expected in the near term (generally less than 90 days), then the loan will not be placed on nonaccrual status. When interest accruals are discontinued, unpaid interest recognized in income in the current year is reversed, and unpaid interest accrued in prior years is charged to the allowance for credit losses. United’s method of income recognition for loans and leases that are classified as nonaccrual is to recognize interest income on a cash basis or apply the cash receipt to principal when the ultimate collectability of principal is in doubt. Nonaccrual loans and leases will not normally be returned to accrual status unless all past due principal and interest has been paid and the borrower has evidenced their ability to meet the contractual provisions of the note.

The following table sets forth United’s age analysis of its past due loans and leases, segregated by class of loans and leases:

In some cases, United will modify a loan to a borrower experiencing financial difficulty by providing multiple types of concessions such as a term extension, principal forgiveness, an interest rate reduction or a combination thereof. The following table presents the amortized cost of loans and leases to borrowers experiencing financial difficulty modified during the first three months of 2024 and 2023, respectively, by class of financing receivable and by type of modification.

As of March 31, 2024 and December 31, 2023, there were commitments to lend additional funds of $718 and $28, respectively, to debtors owing loan receivables whose terms have been modified.

United’s estimate of future credit losses uses a lifetime methodology, derived from modeled loan performance based on the extensive historical experience of loans with similar risk characteristics, adjusted to reflect current conditions and reasonable and supportable forecasts. The historical loss experience used in United’s credit loss models includes the impact of loan modifications provided to borrowers experiencing financial difficulty, and also includes the impact of projected loss severities as a result of loan defaults.

United closely monitors the performance of the loans that are modified to borrowers experiencing financial difficulty to understand the effectiveness of its modification efforts. The following table presents the performance in the 12 months after a modification made to borrowers experiencing financial difficulty presented by class of financing receivable:

United elects the practical expedient to measure expected credit losses on collateral dependent loans and leases based on the difference between the loan’s amortized cost and the collateral’s fair value, adjusted for selling costs. The following table presents the amortized cost basis of collateral-dependent loans and leases in which repayment is expected to be derived substantially through the operation or sale of the collateral and where the borrower is experiencing financial difficulty, by class of loans and leases as of March 31, 2024 and December 31, 2023:

United categorizes loans and leases into risk categories based on relevant information about the ability of borrowers to service their debt: current financial information, historical payment experience, credit documentation, underlying collateral (if any), public information and current economic trends, among other factors.

United uses the following definitions for risk ratings:

• Pass

• Special Mention

• Substandard

• Doubtful

For United’s loans with a corporate credit exposure, United analyzes loans individually to classify the loans as to credit risk. Review and analysis of criticized (special mention-rated loans in the amount of $1,000 or greater) and classified (substandard-rated and worse in the amount of $500 and greater) loans is completed once per quarter. Review of notes with committed exposure of $2,000 or greater is completed at least annually. For loans with a consumer credit exposure, United internally assigns a grade based upon an individual loan’s delinquency status. United reviews and updates, as necessary, these grades on a quarterly basis.

Special mention loans, with a corporate credit exposure, have potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loans or in the Company’s credit position at some future date. Borrowers may be experiencing adverse operating trends (declining revenues or margins) or an ill proportioned balance sheet (e.g., increasing inventory without an increase in sales, high leverage, tight liquidity). Adverse economic or market conditions, such as interest rate increases or the entry of a new competitor, may also support a special mention rating. Nonfinancial reasons for rating a credit exposure special mention include management problems, pending litigation, an ineffective loan agreement or other material structural weakness, and any other significant deviation from prudent lending practices. For loans with a consumer credit exposure, loans that are past due 30-89 days are generally considered special mention.

A substandard loan with a corporate credit exposure is inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness, or weaknesses, that jeopardize the liquidation of the debt by the borrower. They are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. They require more intensive supervision by management. Substandard loans are generally characterized by current or expected unprofitable operations, inadequate debt service coverage, inadequate liquidity, or marginal capitalization. Repayment may depend on collateral or other credit risk mitigants. For some substandard loans, the likelihood of full collection of interest and principal may be in doubt and thus, placed on nonaccrual. For loans with a consumer credit exposure, loans that are 90 days or more past due or that have been placed on nonaccrual are considered substandard.

A loan with corporate credit exposure is classified as doubtful if it has all the weaknesses inherent in one classified as substandard with the added characteristic that the weaknesses make collection in full, on the basis of currently existing facts, conditions, and values, highly questionable. A doubtful loan has a high probability of total or substantial loss, but because of specific pending events that may strengthen the loan, its classification as loss is deferred. Doubtful borrowers are usually in default, lack adequate liquidity or capital, and lack the resources necessary to remain an operating entity. Pending events can include mergers, acquisitions, liquidations, capital injections, the perfection of liens on additional collateral, the valuation of collateral, and refinancing. Generally, there are not any loans with a consumer credit exposure that are classified as doubtful. Usually, they are charged-off prior to such a classification.

Based on the most recent analysis performed, the risk category of loans and leases as well as charge-offs and recoveries by class of loans is as follows:

At March 31, 2024 and December 31, 2023, other real estate owned (“OREO”) included in other assets in the Consolidated Balance Sheets was $2,670 and $2,615, respectively. OREO consists of real estate acquired in foreclosure or other settlement of loans. Such assets are carried at the lower of the investment in the assets or the fair value of the assets less estimated selling costs. Any adjustment to the fair value at the date of transfer is charged against the allowance for loan losses. Any subsequent valuation adjustments as well as any costs relating to operating, holding or disposing of the property are recorded in other expense in the period incurred. At March 31, 2024 and December 31, 2023, the recorded investment of consumer mortgage loans secured by residential real estate properties for which formal foreclosure proceedings are in process was $258 and $142, respectively.

Allowance for Credit Losses

5. ALLOWANCE FOR CREDIT LOSSES

The allowance for loan losses is an estimate of the expected credit losses on financial assets measured at amortized cost to present the net amount expected to be collected as of the balance sheet date. Such allowance is based on the credit losses expected to arise over the life of the asset (contractual term). Assets are charged off when United determines that such financial assets are deemed uncollectible or based on regulatory requirements, whichever is earlier. Charge-offs are recognized as a deduction from the allowance for credit losses. Expected recoveries of amounts previously charged-off, not to exceed the aggregate of the amount previously charged-off, are included in determining the necessary reserve at the balance sheet date.

United made a policy election to present the accrued interest receivable balance separately in its consolidated balance sheets from the amortized cost of a loan. Accrued interest receivable was $91,178 and $88,963 at March 31, 2024 and December 31, 2023, respectively, related to loans and leases are included separately in “Accrued interest receivable” in the consolidated balance sheets. For all classes of loans and leases receivable, the accrual of interest is discontinued when the contractual payment of principal or interest has become 90 days past due, unless the loan is well secured and in the process of collection. Interest received on nonaccrual loans and leases, generally is either applied against principal or reported as interest income, according to management’s judgment as to the collectability of principal.

The following table represents the accrued interest receivable as of March 31, 2024 and December 31, 2023:

	Accrued Interest Receivable
	At March 31, 2024		At December 31, 2023
Commercial Real Estate:
Owner-occupied	$	4,662	$	4,751

United estimates the allowance balance using relevant available information, from internal and external sources, relating to past events, current conditions and reasonable and supportable forecasts. Historical credit loss experience provides the basis for the estimation of expected credit losses. Adjustments to historical loss information are made for differences in current loan-specific risk characteristics such as differences in underwriting standards, portfolio mix, delinquency level or term as well as reasonable and supportable forecast adjustments for changes in environmental conditions, such as changes in unemployment rates, property values or other relevant factors. A reversion to historical loss data occurs via a straight-line method during the year following the one-year reasonable and supportable forecast period.

United pools its loans and leases based on similar risk characteristics in estimating expected credit losses. United has identified the following portfolio segments and measures the allowance for credit losses using the following methods:

• Method: Probability of Default/Loss Given Default (PD/LGD)

• Commercial Real Estate Owner-Occupied

• Commercial Real Estate Nonowner-Occupied

• Commercial Other

• Method: Cohort

• Residential Real Estate

• Construction & Land Development

• Consumer

• Bankcard

Risk characteristics of commercial real estate owner-occupied loans and commercial other loans and leases are similar in that they are normally dependent upon the borrower’s internal cash flow from operations to service debt. Commercial real estate nonowner-occupied loans differ in that cash flow to service debt is normally dependent on external income from third parties for use of the real estate such as rents, leases and room rates. Residential real estate loans are dependent upon individual borrowers who are affected by changes in general economic conditions, demand for housing and resulting residential real estate valuation. Construction and land development loans are impacted mainly by demand whether for new residential housing or for retail, industrial, office and other types of commercial construction within a given area. Consumer loan pool risk characteristics are influenced by general, regional and local economic conditions.

Loans that do not share risk characteristics are evaluated on an individual basis. Loans evaluated individually are not also included in the collective evaluation. When management determines that foreclosure is probable or when the borrower is experiencing financial difficulty at the reporting date and repayment is expected to be provided substantially through the operation or sale of the collateral but may also include other non-performing loans, expected credit losses are based on the fair value of the collateral at the reporting date, adjusted for selling costs as appropriate. These individually evaluated loans are removed from their respective pools and typically represent collateral dependent loans.

Expected credit losses are estimated over the contractual term of the loans and leases, adjusted for expected prepayments when appropriate. The contractual term excludes expected extensions, renewals and modifications unless management has a reasonable expectation at the reporting date that the extension or renewal options are included in the original or modified contract at the reporting date and are not unconditionally cancelable by United.

At the acquisition date, an initial allowance for expected credit losses for non-PCD loans is estimated and recorded as credit loss expense. The subsequent measurement of expected credit losses for all acquired loans is the same as the subsequent measurement of expected credit losses for originated loans. For allowance for credit losses under ASC Topic 326 calculation purposes, United includes its acquired loans and leases in their relevant pool unless they meet the criteria for specific review.

United maintains an allowance for loan losses and a reserve for lending-related commitments such as unfunded loan commitments and letters of credit. The reserve for lending-related commitments of $42,915 and $44,706 at March 31, 2024 and December 31, 2023, respectively, is separately classified on the balance sheet and is included in other liabilities. The combined allowance for loan losses and reserve for lending-related commitments is considered the allowance for credit losses.

United’s allowance for credit losses at March 31, 2024 was relatively flat from December 31, 2023, increasing $1,877 or less than 1%. This slight increase was due mainly to increases in the loan loss reserves for the commercial real estate, both owner and non-owner occupied, the residential real estate and the other commercial loans segments due to increased outstanding loan balances and increased adjustments resulting from the reasonable and supportable forecast.

The first quarter of 2024 qualitative adjustments include analyses of the following:

• Current conditions – United considered the impact of inflation, interest rates, the banking regulatory environment and geopolitical conflict when making determinations related to factor adjustments for the external environment. United also considered portfolio trends related to economic and business conditions, collateral values for dependent loans; past due, nonaccrual and graded loans and leases; and concentrations of credit.

• Reasonable and supportable forecasts – The forecast is determined on a portfolio-by-portfolio basis by relating the correlation of real GDP and the unemployment rate to loss rates to forecasts of those variables. The reasonable and supportable forecast selection is subjective in nature and requires more judgment compared to the other components of the allowance. Assumptions for the economic variables were the following:

• The forecast for real GDP in 2024 increased in the first quarter, from a projection of 1.40% for 2024 at the end of 2023 to 2.10% for 2024 with a slightly smaller increase for 2025, from a projection of 1.80% for 2025 at the end of 2023 to 2.00% for 2025. The unemployment rate remained fairly consistent to the end of 2023 with a steady trend expected throughout 2024 and 2025.

• Greater risk of loss is probable in the office portfolio due to continued hybrid and remote work that may be exacerbated by future economic conditions as well as higher interest rates and cap rates.

• Reversion to historical loss data occurs via a straight-line method during the year following the one-year reasonable and supportable forecast period.

A progression of the allowance for loan and lease losses, by portfolio segment, for the periods indicated is summarized as follows:

Mortgage Servicing Rights

7. MORTGAGE SERVICING RIGHTS

Mortgage loans serviced for others are not included in the accompanying Consolidated Balance Sheets. The value of mortgage servicing rights (“MSRs”) is included on the Company’s Consolidated Balance Sheets.

The Company initially measures servicing assets and liabilities retained related to the sale of residential loans held for sale (“MSRs”) at fair value, if practicable. For subsequent measurement purposes, the Company measures servicing assets and liabilities based on the lower of cost or market using the amortization method. MSRs are amortized in proportion to, and over the period of, estimated net servicing income. The amortization of the MSRs is analyzed periodically and is adjusted to reflect changes in prepayment rates and other estimates.

The Company evaluates potential impairment of MSRs based on the difference between the carrying amount and current estimated fair value of the servicing rights. In determining impairment, the Company aggregates all servicing rights and stratifies them into tranches based on predominant risk characteristics. If impairment exists, a valuation allowance is established for any excess of amortized cost over the current estimated fair value by a charge to income. If the Company later determines that all or a portion of the impairment no longer exists for a particular tranche, a reduction of the allowance may be recorded as an increase to income.

Service fee income is recorded for fees earned for servicing mortgage loans under servicing agreements with the Federal National Mortgage Association (“FNMA”), the Federal Home Loan Mortgage Corporation (“FHLMC”) and certain private investors. The fees are based on a contractual percentage of the outstanding principal balance of the loans serviced and are recorded in noninterest income. Amortization of MSRs and mortgage servicing costs are charged to expense when incurred.

The unpaid principal balances of loans serviced for others were approximately $1,173,246 at March 31, 2024 and $1,202,448 at December 31, 2023.

The estimated fair value of the mortgage servicing rights was $13,439 and $13,427 at March 31, 2024 and December 31, 2023, respectively. The estimated fair value of servicing rights at March 31, 2024 was determined using a net servicing fee of 0.25%, average discount rates ranging from 10.19% to 11.15% with a weighted average discount rate of 10.59%, average constant prepayment rates (“CPR”) ranging from 7.62% to 9.96% with a weighted average prepayment rate of 9.16%, depending upon the stratification of the specific servicing right, and a delinquency rate, including loans on forbearance of 2.65%. The estimated fair value of servicing rights at December 31, 2023 was determined using a net servicing fee of 0.25%, average discount rates ranging from 10.50% to 10.82% with a weighted average discount rate of 10.58%, average constant prepayment rates (“CPR”) ranging from 7.84% to 10.25% with a weighted average prepayment rate of 9.43%, depending upon the stratification of the specific servicing right, and a delinquency rate, including loans on forbearance of 3.29%. Please refer to Note 13 in these Notes to Consolidated Financial Statements for additional information concerning the fair value of MSRs.

The following presents the activity in mortgage servicing rights, including their valuation allowance for the three months ended March 31, 2024 and 2023:

	Three Months Ended March 31, 2024			Three Months Ended March 31, 2023

The Company did not record any temporary impairments on mortgage servicing rights for the three months ended March 31, 2024 and 2023.

The estimated amortization expense is based on current information regarding future loan payments and prepayments. Amortization expense could change in future periods based on changes in the volume of prepayments and economic factors.

Leases [Abstract]

Leases

8. LEASES

United determines if an arrangement is a lease at inception. United and certain subsidiaries have entered into various noncancelable-operating leases for branch and loan production offices as well as operating facilities. Operating leases are included in operating lease right-of-use (“ROU”) assets and operating lease liabilities on the Consolidated Balance Sheets. Operating leases with an initial term of 12 months or less are not recorded on the Consolidated Balance Sheets. Presently, United does not have any finance leases.

United’s operating leases are subject to renewal options under various terms. United’s operating leases have remaining terms of 1 to 15 years, some of which include options to extend leases generally for periods of 5 years. United rents or subleases certain real estate to third parties. Our sublease portfolio generally consists of operating leases to other organizations for former branch offices.

ROU assets represent United’s right to use an underlying asset for the lease term and lease liabilities represent United’s obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of United’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The operating lease ROU asset also includes any lease payments made and excludes lease incentives. Lease terms may include options to extend the lease when it is reasonably certain that United will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term.

The components of lease expense were as follows:

Federal funds purchased and securities sold under agreements to repurchase have not been a significant source of funds for the company. The securities sold under agreements to repurchase were accounted for as collateralized financial transactions. They were recorded at the amounts at which the securities were acquired or sold plus accrued interest.

United has various unused lines of credit available from certain of its correspondent banks in the aggregate amount of $280,000. These lines of credit, which bear interest at prevailing market rates, permit United to borrow funds in the overnight market, and are renewable annually subject to certain conditions.

United has a $20,000 line of credit with an unrelated financial institution to provide for general liquidity needs. The line is an unsecured, revolving line of credit. The line is renewable on a 360 day basis and carries an indexed, floating-rate of interest. The line requires compliance with various financial and nonfinancial covenants. At March 31, 2024, United had no outstanding balance under this credit.

Long-Term Borrowings

10. LONG-TERM BORROWINGS

United’s subsidiary bank is a member of the Federal Home Loan Bank (“FHLB”). Membership in the FHLB makes available short-term and long-term borrowings from collateralized advances. All FHLB borrowings are collateralized by a mix of single-family residential mortgage loans, commercial loans and investment securities. At March 31, 2024, United had an unused borrowing amount of approximately $7,001,680 available subject to delivery of collateral after certain trigger points. Advances may be called by the FHLB or redeemed by United based on predefined factors and penalties.

At March 31, 2024, $1,460,415 of FHLB advances with a weighted-average contractual interest rate of 5.43% and a weighted-average effective interest rate of 3.70% are scheduled to mature within the next two years. The weighted-average effective rate considers the effect of any interest rate swaps designated as cash flow hedges outstanding at March 31, 2024 to manage interest rate risk on its long-term debt.

The scheduled maturities of these FHLB borrowings are as follows:

Year	Amount
2024	$	1,450,000
2025		10,415
2026		0
2027		0
2028 and thereafter		0
Total	$	1,460,415

At March 31, 2024, United had a total of twenty statutory business trusts that were formed for the purpose of issuing or participating in pools of trust preferred capital securities (“Capital Securities”) with the proceeds invested in junior subordinated debt securities (“Debentures”) of United. The Debentures, which are subordinate and junior in right of payment to all present and future senior indebtedness and certain other financial obligations of United, are the sole assets of the trusts and United’s payment under the Debentures is the sole source of revenue for the trusts. At March 31, 2024 and December 31, 2023, the outstanding balance of the Debentures was $279,019 and $278,616, respectively, and was included in the category of long-term debt on the Consolidated Balance Sheets entitled “Other long-term borrowings.” The Capital Securities are not included as a component of shareholders’ equity in the Consolidated Balance Sheets. United fully and unconditionally guarantees each individual trust’s obligations under the Capital Securities.

Under the provisions of the subordinated debt, United has the right to defer payment of interest on the subordinated debt at any time, or from time to time, for periods not exceeding five years. If interest payments on the subordinated debt are deferred, the dividends on the Capital Securities are also deferred. Interest on the subordinated debt is cumulative.

In accordance with the fully-phased in “Basel III Capital Rules” as published by United’s primary federal regulator, the Federal Reserve, United is unable to consider the Capital Securities as Tier 1 capital, but rather the Capital Securities are included as a component of United’s Tier 2 capital. United can include the Capital Securities in its Tier 2 capital on a permanent basis.

Commitments and Contingent Liabilities

11. COMMITMENTS AND CONTINGENT LIABILITIES

Lending-related Commitments

United is a party to financial instruments with off-balance-sheet risk in the normal course of business to meet the financing needs of its customers and to alter its own exposure to fluctuations in interest rates. These financial instruments include loan commitments, standby letters of credit, and interest rate swap agreements. The instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the financial statements.

United’s maximum exposure to credit loss in the event of nonperformance by the counterparty to the financial instrument for the loan commitments and standby letters of credit is the contractual or notional amount of those instruments. United uses the same policies in making commitments and conditional obligations as it does for on-balance sheet instruments. Collateral may be obtained, if deemed necessary, based on management’s credit evaluation of the counterparty.

Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the commitment contract. Commitments generally have fixed expiration dates or other termination clauses and may require the payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily, and historically do not, represent future cash requirements. The amount of collateral obtained, if deemed necessary upon the extension of credit, is based on management’s credit evaluation of the counterparty. United had approximately $6,817,449 and $6,851,890 of loan commitments outstanding as of March 31, 2024 and December 31, 2023, respectively, approximately 41% of which contractually expire within one year. Excluded in the December 31, 2023 amount above were commitments to extend credit of $416,095 related to mortgage loan funding commitments of United’s previous mortgage banking segment which were of a short-term nature.

Commercial and standby letters of credit are agreements used by United’s customers as a means of improving their credit standing in their dealings with others. Under these agreements, United guarantees certain financial commitments of its customers. A commercial letter of credit is issued specifically to facilitate trade or commerce. Typically, under the terms of a commercial letter of credit, a commitment is drawn upon when the underlying transaction is consummated as intended between the customer and a third party. As of March 31, 2024 and December 31, 2023, United had $16,113 and $16,233 of commercial letters of credit outstanding. A standby letter of credit is generally contingent upon the failure of a customer to perform according to the terms of an underlying contract with a third party. United has issued standby letters of credit of $155,354 and $147,705 as of March 31, 2024 and December 31, 2023, respectively. In accordance with the Contingencies Topic of the FASB Accounting Standards Codification, United has determined that substantially all of its letters of credit are renewed on an annual basis and the fees associated with these letters of credit are immaterial.

Mortgage Banking

Related to its mortgage banking activities, United provides for its estimated exposure to repurchase loans previously sold to investors for which borrowers failed to provide full and accurate information on their loan application or for which appraisals have not been acceptable or where the loan was not underwritten in accordance with the loan program specified by the loan investor, and for other exposure to its investors related to loan sales activities. United evaluates the merits of each claim and estimates its reserve based on actual and expected claims received and considers the historical amounts paid to settle such claims. United’s reserve was immaterial as of March 31, 2024 and December 31, 2023.

United has derivative counter-party risk that may arise from the possible inability of United’s mortgage banking third party investors to meet the terms of their forward sales contracts. United works with mortgage banking third-party investors that are generally well-capitalized, are investment grade and exhibit strong financial performance to mitigate this risk. United does not expect any third-party investor to fail to meet its obligation.

Legal Proceedings

United and its subsidiaries are currently involved in various legal proceedings in the normal course of business. On at least a quarterly basis, United assesses its liabilities and contingencies in connection with all pending or threatened claims and litigation, utilizing the most recent information available. On a matter-by-matter basis, an accrual for loss is established for those matters which United believes it is probable that a loss may be incurred and that the amount of such loss can be reasonably estimated. Once established, each accrual is adjusted as appropriate to reflect any subsequent developments. Accordingly, management’s estimate will change from time to time, and actual losses may be more or less than the current estimate. For matters where a loss is not probable, or the amount of the loss cannot be estimated, no accrual is established.

Management is vigorously pursuing all its legal and factual defenses and, after consultation with legal counsel, believes that all such litigation will be resolved with no material effect on United’s financial statements.

Regulatory Matters

A variety of consumer products, including mortgage and deposit products, and certain fees and charges related to such products, have come under increased regulatory scrutiny. It is possible that regulatory authorities could bring enforcement actions, including civil money penalties, or take other actions against United in regard to these consumer products. United could also determine of its own accord, or be required by regulators, to refund or otherwise make remediation payments to customers in connection with these products. It is not possible at this time for management to assess the probability of a material adverse outcome or reasonably estimate the amount of any potential loss related to such matters.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Financial Instruments

12. DERIVATIVE FINANCIAL INSTRUMENTS

United uses derivative instruments to help aid against adverse price changes or interest rate movements on the value of certain assets or liabilities and on future cash flows. These derivatives may consist of interest rate swaps, caps, floors, collars, futures, forward contracts, written and purchased options. United also executes derivative instruments with its commercial banking customers to facilitate its risk management strategies.

Derivative instruments designated in a hedge relationship to mitigate exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivative instruments designated in a hedge relationship to mitigate exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges.

Fair value hedges may be eligible for offset on the consolidated balance sheets because they are subject to master netting arrangements or similar agreements. United has elected not to offset the assets and liabilities subject to such arrangements on the consolidated financial statements.

During 2020, United entered into two interest rate swap derivatives designated as cash flow hedges. The notional amount of these cash flow hedge derivatives totaled $500,000. The derivatives are intended to hedge the changes in cash flows associated with floating rate FHLB borrowings. As of March 31, 2024, United has determined that no forecasted transactions related to its cash flow hedges resulted in gains or losses pertaining to cash flow hedge reclassification from AOCI to income because the forecasted transactions became probable of not occurring. United estimates that $16,625 will be reclassified from AOCI as a decrease to interest expense over the next 12-months following March 31, 2024 related to the cash flow hedges. As of March 31, 2024, the maximum length of time over which forecasted transactions are hedged is six years.

At inception of a hedge relationship, United formally documents the hedged item, the particular risk management objective, the nature of the risk being hedged, the derivative being used, how effectiveness of the hedge will be assessed

and how the ineffectiveness of the hedge will be measured. United also assesses hedge effectiveness at inception and on an ongoing basis using regression analysis. Hedge ineffectiveness is measured by using the change in fair value method. The change in fair value method compares the change in the fair value of the hedging derivative to the change in the fair value of the hedged exposure, attributable to changes in the benchmark rate.

United is subject to the Dodd-Frank Act clearing requirement for eligible derivatives. United has executed and cleared eligible derivatives through the London Clearing House (“LCH”). Variation margin at the LCH is distinguished as settled-to-market and settled daily based on the prior day value, rather than collateralized-to-market. The daily settlement of the derivative exposure does not change or reset the contractual terms of the instrument. The total notional amount of interest rate swap derivatives designated as cash flow hedges cleared through the LCH include $500,000 for asset derivatives as of March 31, 2024. Balances related to LCH are presented as a single unit of account with the fair value of the designated cash flow interest rate swap asset being reduced by variation margin posted by (with) the applicable counterparty and reported in the following table on a net basis. The related fair value on a net basis approximates zero.

United through its mortgage banking channel enters into interest rate lock commitments to finance residential mortgage loans with its customers. These commitments, which contain fixed expiration dates, offer the borrower an interest rate guarantee provided the loan meets underwriting guidelines and closes within the timeframe established by United. Interest rate risk arises on these commitments and subsequently closed loans if interest rates change between the time of the interest rate lock and the delivery of the loan to the investor. Market risk on interest rate lock commitments and mortgage loans held for sale is managed using corresponding forward mortgage loan sales contracts. United is a party to these forward mortgage loan sales contracts to sell loans with servicing either released or retained and short sales of mortgage-backed securities. When the interest rate is locked with the borrower, the rate lock commitment, forward sale agreement, and mortgage-backed security position are undesignated derivatives and marked to fair value through earnings. The fair value of the rate lock derivative is measured using valuations from investors for loans with similar characteristics as well as considering the probability of the loan closing (i.e. the “pull-through” rate) with some adjusted for the Company’s actual sales experience versus the investor’s indicated pricing. Fair values of TBA mortgage-backed securities are measured using valuations from investors for mortgage-backed securities with similar characteristics. Income from mortgage banking activities includes the gain recognized for the period presented and associated elements of fair value.

Derivative contracts involve the risk of dealing with both bank customers and institutional derivative counterparties and their ability to meet contractual terms. Credit risk arises from the possible inability of counterparties to meet the terms of their contracts. United’s exposure is limited to the replacement value of the contracts rather than the notional amount of the contract. The Company’s agreements generally contain provisions that limit the unsecured exposure up to an agreed upon threshold. Additionally, the Company attempts to minimize credit risk through certain approval processes established by management.

Fair Value Disclosures [Abstract]

Fair Value Measurements

13. FAIR VALUE MEASUREMENTS

United determines the fair values of its financial instruments based on the fair value hierarchy established in ASC Topic 820, which also clarifies that fair value of certain assets and liabilities is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants.

ASC Topic 820 specifies a hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect United’s market assumptions.

The three levels of the fair value hierarchy based on these two types of inputs are as follows:

	Level 1	-	Valuation is based on quoted prices in active markets for identical assets and liabilities.
	Level 2	-	Valuation is based on observable inputs including quoted prices in active markets for similar assets and liabilities, quoted prices for identical or similar assets and liabilities in less active markets, and model-based valuation techniques for which significant assumptions can be derived primarily from or corroborated by observable data in the market.
	Level 3	-	Valuation is based on model-based techniques that use one or more significant inputs or assumptions that are unobservable in the market.

When determining the fair value measurements for assets and liabilities, United looks to active and observable markets to price identical assets or liabilities whenever possible and classifies such items in Level 1. When identical assets and liabilities are not traded in active markets, United looks to market observable data for similar assets and liabilities and classifies such items as Level 2. Nevertheless, certain assets and liabilities are not actively traded in observable markets and United must use alternative valuation techniques using unobservable inputs to determine a fair value and classifies such items as Level 3. For assets and liabilities that are not actively traded, the fair value measurement is based primarily upon estimates that require significant judgment. Therefore, the results may not be realized in an actual sale or immediate

settlement of the asset or liability. Additionally, there are inherent weaknesses in any calculation technique, and changes in the underlying assumptions used, including discount rates and estimates of future cash flows, could significantly affect the results of current or future values. The level within the fair value hierarchy is based on the lowest level of input that is significant in the fair value measurement.

In accordance with ASC Topic 820, the following describes the valuation techniques used by United to measure certain financial assets and liabilities recorded at fair value on a recurring basis in the financial statements.

Securities available for sale and equity securities: Securities available for sale and equity securities are recorded at fair value on a recurring basis. Fair value measurement is based upon quoted market prices, when available (“Level 1”). If quoted market prices are not available, fair values are measured utilizing independent valuation techniques of identical or similar securities for which significant assumptions are derived primarily from or corroborated by observable market data. Using a market approach valuation methodology, third party vendors compile prices based on observable market inputs, which include benchmark yields, reported trades, issuer spreads, benchmark securities, and “To Be Announced” prices (“Level 2”). Management internally reviews the fair values provided by third party vendors on a monthly basis. Management also performs a quarterly price testing analysis at the individual security level which compares the pricing provided by the third party vendors to an independent pricing source’s valuation of the same securities. Variances that are deemed to be material are reviewed by management. Additionally, to further assess the reliability of the information received from third party vendors, management obtains documentation from third party vendors related to the sources, methodologies, and inputs utilized in valuing securities classified as Level 2. Management analyzes this information to ensure the underlying assumptions appear reasonable. Management also obtains an independent service auditor’s report from third party vendors to provide reasonable assurance that appropriate controls are in place over the valuation process. Upon completing its review of the pricing from third party vendors at March 31, 2024, management determined that the prices provided by its third party pricing sources were reasonable and in line with management’s expectations for the market values of these securities. Therefore, prices obtained from third party vendors that did not reflect forced liquidation or distressed sales were not adjusted materially by management at March 31, 2024. Management utilizes a number of factors to determine if a market is inactive, all of which may require a significant level of judgment. Factors that management considers include: a significant widening of the bid-ask spread, a considerable decline in the volume and level of trading activity in the instrument, a significant variance in prices among market participants, and a significant reduction in the level of observable inputs. Any securities available for sale not valued based upon quoted market prices or third party pricing models that consider observable market data are considered Level 3. Currently, United does not have any available-for-sale securities considered as Level 3.

Loans held for sale: For residential mortgage loans sold, the loans closed are recorded at fair value using the fair value option which is measured using valuations from investors for loans with similar characteristics (“Level 2”) with some adjusted for the Company’s actual sales experience versus the investor’s indicated pricing (“Level 3”). The unobservable input for Level 3 valuations is the Company’s historical sales prices. For March 31, 2024, the range of historical sales prices increased the investor’s indicated pricing by a range of 0.001% to 0.392% with a weighted average increase of 0.140%.

Derivatives: United utilizes interest rate swaps to hedge exposure to interest rate risk and variability of cash flows associated to changes in the underlying interest rate of the hedged item. These hedging interest rate swaps are classified as either a fair value hedge or a cash flow hedge. United utilizes third-party vendors for derivative valuation purposes. These vendors determine the appropriate fair value based on a net present value calculation of the cash flows related to the interest rate swaps using primarily observable market inputs such as interest rate yield curves (“Level 2”). Valuation adjustments to derivative fair values for liquidity and credit risk are also taken into consideration, as well as the likelihood of default by United and derivative counterparties, the net counterparty exposure and the remaining maturities of the positions. Values obtained from third party vendors are typically not adjusted by management. Management internally reviews the derivative values provided by third party vendors on a quarterly basis. All derivative values are tested for reasonableness by management utilizing a net present value calculation.

For a fair value hedge, the fair value of the interest rate swap is recognized on the balance sheet as either a freestanding asset or liability with a corresponding adjustment to the hedged financial instrument. Subsequent adjustments due to changes in the fair value of a derivative that qualifies as a fair value hedge are offset in current period earnings either in interest income or interest expense depending on the nature of the hedged financial instrument. For a cash flow hedge, the fair value of the interest rate swap is recognized on the balance sheet as either a freestanding asset or liability with a corresponding adjustment to accumulated other comprehensive income within shareholders’ equity, net of tax. Subsequent adjustments due to changes in the fair value of a derivative that qualifies as a cash flow hedge are offset to accumulated other comprehensive income, net of tax and reclassified into earnings in the same line associated with the forecasted transaction when the forecasted transaction affects earnings.

The Company records its interest rate lock commitments and forward loan sales commitments at fair value determined as the amount that would be required to settle each of these derivative financial instruments at the balance sheet date. In the normal course of business, United, through its mortgage banking channel, enters into contractual interest rate lock commitments to extend credit to borrowers with fixed expiration dates. The commitments become effective when the borrowers “lock-in” a specified interest rate within the timeframes established by the mortgage companies. All borrowers are evaluated for credit worthiness prior to the extension of the commitment. Interest rate risk arises if interest rates move adversely between the time of the interest rate lock by the borrower and the sale date of the loan to the investor. To mitigate the effect of the interest rate risk inherent in providing rate lock commitments to borrowers, United, through its mortgage banking channel, enters into either a forward sales contract to sell loans to investors or a TBA mortgage-backed security. Fair values of TBA mortgage-backed securities are measured using valuations from investors for mortgage-backed securities with similar characteristics (“Level 2”). The forward sales contracts lock in an interest rate and price for the sale of loans similar to the specific rate lock commitments. These valuations fall into a Level 2 category. The interest rate lock commitments are recorded at fair value which is measured using valuations from investors for loans with similar characteristics (“Level 2”) with some adjusted for the Company’s actual sales experience versus the investor’s indicated pricing (“Level 3”). The unobservable input for Level 3 valuations is the Company’s historical sales prices. For March 31, 2024, the range of historical sales prices increased the investor’s indicated pricing by a range of 0.001% to 0.392% with a weighted average increase of 0.140%.

For interest rate swap derivatives that are not designated in a hedge relationship within United’s mortgage banking activities, changes in the fair value of the derivatives are recognized in income from mortgage banking activities in the same period as the change in the fair value. Unrealized gains and losses due to changes in the fair value of other derivative financial instruments not in hedge relationships are included in noninterest income and noninterest expense, respectively.

The following tables present the balances of financial assets and liabilities measured at fair value on a recurring basis as of March 31, 2024 and December 31, 2023, segregated by the level of the valuation inputs within the fair value hierarchy.

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis

Certain financial assets are measured at fair value on a nonrecurring basis in accordance with GAAP. Adjustments to the fair value of these assets usually result from the application of lower-of-cost-or-market accounting or write-downs of individual assets.

The following describes the valuation techniques used by United to measure certain financial assets recorded at fair value on a nonrecurring basis in the financial statements.

Individually assessed loans: In the determination of the allowance for loan losses, loans that do not share risk characteristics are evaluated on an individual basis. Loans evaluated individually are not also included in the collective evaluation. When management determines that foreclosure is probable or when the borrower is experiencing financial difficulty at the reporting date and repayment is expected to be provided substantially through the operation or sale of the collateral, expected credit losses are based on the fair value of the collateral at the reporting date, adjusted for selling costs as appropriate. Fair value is measured using a market approach based on the value of the collateral securing the loans. Collateral may be in the form of real estate or business assets including equipment, inventory, and accounts receivable. The vast majority of the collateral is real estate. The value of real estate collateral is determined utilizing an appraisal conducted by an independent, licensed appraiser outside of the Company using comparable property sales (“Level 2”). However, if the collateral is a house or building in the process of construction or if an appraisal of the real estate property is over two years old, then the fair value is considered Level 3. The value of business equipment is based upon an outside appraisal if deemed significant, or the net book value on the applicable business’ financial statements if not considered significant using observable market data. Likewise, values for inventory and accounts receivables collateral are based on financial statement balances or aging reports (“Level 3”). For individually assessed loans, a specific reserve is established through the allowance for loan losses, if necessary, by estimating the fair value of the underlying collateral on a nonrecurring basis. Any fair value adjustments are recorded in the period incurred as provision for credit losses expense on the Consolidated Statements of Income.

OREO: OREO consists of real estate acquired in foreclosure or other settlement of loans. Such assets are carried on the balance sheet at the lower of the investment in the assets or the fair value of the assets less estimated selling costs. Fair value is determined by one of two market approach methods depending on whether the property has been vacated and an appraisal can be conducted. If the property has yet to be vacated and thus an appraisal cannot be performed, a Brokers Price Opinion (i.e. BPO), is obtained. A BPO represents a best estimate valuation performed by a realtor based on knowledge of current property values and a visual examination of the exterior condition of the property. Once the property is subsequently vacated, a formal appraisal is obtained and the recorded asset value appropriately adjusted. On the other hand, if the OREO property has been vacated and an appraisal can be conducted, the fair value of the property is determined based upon the appraisal using a market approach. An authorized independent appraiser conducts appraisals for United. Appraisals for property other than ongoing construction are based on consideration of comparable property sales (“Level 2”). In contrast, valuation of ongoing construction assets requires some degree of professional judgment. In conducting an appraisal for ongoing construction property, the appraiser develops two appraised amounts: an “as is” appraised value and a “completed” value. Based on professional judgment and their knowledge of the particular situation, management determines the appropriate fair value to be utilized for such property (“Level 3”). As a matter of policy, valuations are reviewed at least annually and appraisals are generally updated on a bi-annual basis with values lowered as necessary.

Intangible Assets: For United, intangible assets consist of goodwill and core deposit intangibles. Goodwill is tested for impairment at least annually or sooner if indicators of impairment exist. United may elect to perform a qualitative analysis to determine whether or not it is more-likely-than not that the fair value of a reporting unit is less than its carrying amount. If United elects to bypass this qualitative analysis, or concludes via qualitative analysis that it is more-likely-than-not that the fair value of a reporting unit is less than its carrying value, United may use either a market or income quantitative approach to determine the fair value of the reporting unit. If the fair value of the reporting unit is less than its carrying value, an impairment charge would be recorded for the difference, not to exceed the amount of goodwill allocated to the reporting unit. At each reporting date, the Company considers potential indicators of impairment. United performed its annual goodwill impairment test on the Company’s reporting units as of September 30, 2023. The goodwill impairment test did not identify any goodwill impairment. In subsequent periods, economic uncertainty, market volatility and the performance of the Company’s stock as well as possible other impairment indicators could cause us to perform a goodwill impairment test which could result in an impairment charge being recorded for that period if the carrying value of goodwill was found to exceed fair value. Core deposit intangibles relate to the estimated value of the deposit base of acquired institutions. Management reviews core deposit intangible assets on an annual basis, or sooner if indicators of

impairment exist, and evaluates changes in facts and circumstances that may indicate impairment in the carrying value. During the fourth quarter of 2023, United’s management formulated a plan to consolidate its mortgage delivery channels by consolidating George Mason’s and Crescent’s mortgage banking business into United Bank. As a result of this consolidation decision, United impaired the trade names intangibles at George Mason and Crescent to zero at December 31, 2023. No fair value measurement of intangible assets was made during the first three months of 2024 and 2023.

Mortgage Servicing Rights (“MSRs”): A mortgage servicing right asset represents the amount by which the present value of the estimated future net cash flows to be received from servicing loans are expected to more than adequately compensate the Company for performing the servicing. The Company initially measures servicing assets and liabilities retained related to the sale of residential loans held for sale (“mortgage servicing rights”) at fair value. For subsequent measurement purposes, the Company measures servicing assets and liabilities using the amortization method on a quarterly basis. The quarterly determination of fair value of servicing rights is provided by a third party and is estimated using a present value cash flow model. The most important assumptions used in the valuation model are the anticipated rate of the loan prepayments and discount rates. Although some assumptions in determining fair value are based on standards used by market participants, some are based on unobservable inputs and therefore are classified in Level 3 of the valuation hierarchy. The unobservable inputs for Level 3 valuations are market discount rates, anticipated prepayment speeds, projected delinquency rates, and ancillary fee income net of servicing costs. For the unobservable inputs used in the valuation of mortgage servicing rights at March 31, 2024 and December 31, 2023, refer to Note 7 of these Notes to Consolidated Financial Statements. The Company did not record any temporary impairment of mortgage servicing rights in the quarter ended March 31, 2024 and 2023.

The following table summarizes United’s financial assets that were measured at fair value on a nonrecurring basis during the period:

Fair Value of Other Financial Instruments

The following methods and assumptions were used by United in estimating its fair value disclosures for other financial instruments:

Cash and Cash Equivalents: The carrying amounts reported in the balance sheet for cash and cash equivalents approximate those assets’ fair values.

Securities held to maturity and other securities: The estimated fair values of securities held to maturity are based on quoted market prices, where available. If quoted market prices are not available, fair values are measured utilizing independent valuation techniques of identical or similar securities for which significant assumptions are derived primarily from or corroborated by observable market data. Third party vendors compile prices from various sources and may determine the fair value of identical or similar securities by using pricing models that consider observable market data. Any securities held to maturity, not valued based upon the methods above, are valued based on a discounted cash flow methodology using appropriately adjusted discount rates reflecting nonperformance and liquidity risks. Other securities consist mainly of shares of Federal Home Loan Bank and Federal Reserve Bank stock that do not have readily determinable fair values and are carried at cost.

Loans and leases: The fair values of certain mortgage loans (e.g., one-to-four family residential), credit card loans, and other consumer loans are based on quoted market prices of similar loans sold in conjunction with securitization transactions, adjusted for differences in loan characteristics. The fair values of other loans and leases (e.g., commercial real estate and rental property mortgage loans, commercial and industrial loans, financial institution loans and agricultural loans) are estimated using discounted cash flow analyses, using market interest rates currently being offered for loans and leases with similar terms to borrowers of similar creditworthiness, which include adjustments for liquidity concerns. For acquired PCD loans, fair value is assumed to equal United’s carrying value, which represents the present value of expected future principal and interest cash flows, as adjusted for any Allowance for Credit Losses recorded for these loans.

Deposits: The fair values of demand deposits (e.g., interest and noninterest checking, regular savings and certain types of money market accounts) are, by definition, equal to the amount payable on demand at the reporting date (i.e., their carrying amounts). The carrying amounts of variable-rate, fixed-term money market accounts and certificates of deposit approximate their fair values at the reporting date. Fair values of fixed-rate certificates of deposit are estimated using a discounted cash flow calculation that applies interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities on time deposits.

Short-term Borrowings: The carrying amounts of federal funds purchased, borrowings under repurchase agreements and any other short-term borrowings approximate their fair values.

Long-term Borrowings: The fair values of United’s Federal Home Loan Bank borrowings and trust preferred securities are estimated using discounted cash flow analyses, based on United’s current incremental borrowing rates for similar types of borrowing arrangements.

Summary of Fair Values for All Financial Instruments

The estimated fair values of United’s financial instruments are summarized below:

Stock Based Compensation

14. STOCK BASED COMPENSATION

On May 12, 2020, United’s shareholders approved the 2020 Long-Term Incentive Plan (“2020 LTI Plan”). The 2020 LTI Plan became effective May 13, 2020. An award granted under the 2020 LTI Plan may consist of any non-qualified stock options or incentive stock options, stock appreciation rights (“SARs”), restricted stock, restricted stock units, performance units or other-stock-based award. These awards all relate to the common stock of United. The maximum number of shares of United common stock which may be issued under the 2020 LTI Plan is 2,300,000. The 2020 LTI Plan will be administered by a board committee appointed by United’s Board of Directors (the “Board”). Unless otherwise determined by the Board, the Compensation Committee of the Board (the “Committee”) shall administer the 2020 LTI Plan. The maximum number of options and stock appreciation rights, in the aggregate, which may be awarded to any individual key employee during any calendar year is 100,000. The maximum number of options and stock appreciation rights, in the aggregate, which may be awarded to any non-employee director during any calendar year is 10,000 or, if such Award is payable in cash, the Fair Market Value equivalent thereof. The maximum number of shares of restricted stock or shares subject to a restricted stock units award that may be granted during any calendar year is 225,000 shares to any individual key employee and 10,000 shares to any individual non-employee director. Subject to certain change in control provisions, the 2020 LTI Plan provides that all awards of will vest as the Committee determines in the award agreement, provided that no awards will vest sooner than 1/3 per year over the first three anniversaries of the award. United adopted a clawback policy that applies to named executive officers and other executive officers and permits the Committee to cancel certain awards and to recoup gains realized from previous awards should United be required to prepare an accounting restatement due to materially inaccurate performance metrics. A Form S-8 was filed on May 29, 2020 with the Securities and Exchange Commission to register all the shares which were available for the 2020 LTI Plan. The 2020 LTI Plan replaces the 2016 LTI Plan.

Compensation expense of $3,266 and $2,713 related to the nonvested awards under United’s Long-Term Incentive Plans was incurred for the first quarter of 2024 and 2023, respectively. Compensation expense was included in employee compensation in the unaudited Consolidated Statements of Income.

Stock Options

United currently has options outstanding from various option plans other than the 2020 LTI Plan (the “Prior Plans”); however, no common shares of United stock are available for grants under the Prior Plans as these plans have expired. Awards outstanding under the Prior Plans will remain in effect in accordance with their respective terms. The maximum term for options granted under the plans is ten (10) years.

A summary of activity under United’s stock option plans as of March 31, 2024, and the changes during the first three months of 2024 are presented below:

	Three Months Ended March 31, 2024
	Shares			Aggregate Intrinsic Value		Weighted Average
						Remaining Contractual Term (Yrs.)		Exercise Price
Outstanding at January 1, 2024		1,337,382						$	35.47
Exercised		(25,991	)						27.15
Forfeited or expired		(3,477	)						27.49
Outstanding at March 31, 2024		1,307,914		$	3,440		3.6	$	35.66
Exercisable at March 31, 2024		1,307,914		$	3,440		3.6	$	35.66

The following table summarizes the status of United’s nonvested stock option awards during the first three months of 2024:

	Shares			Weighted-Average Grant Date Fair Value Per Share
Nonvested at January 1, 2024		56,526		$	5.65
Vested		(56,526	)		5.65
Forfeited or expired		0			0.00
Nonvested at March 31, 2024		0		$	0.00

During the three months ended March 31, 2024 and 2023, 25,991 and 55,796 shares, respectively, were issued in connection with stock option exercises. All shares issued in connection with stock option exercises for the three months ended March 31, 2024 and 2023 were issued from authorized and unissued stock. The total intrinsic value of options exercised under the Plans during the three months ended March 31, 2024 and 2023 was $207 and $722 respectively.

As of March 31, 2024, there was no unrecognized compensation cost related to nonvested stock option awards.

Restricted Stock

Under the 2020 LTI Plan, United may award restricted common shares to key employees and non-employee directors. Restricted shares granted to participants will vest no sooner than 1/3 per year over the first three anniversaries of the award. Unless determined by the Committee or the Board and provided in the award agreement, recipients of restricted shares do not pay any consideration to United for the shares, have the right to vote all shares subject to such grant and receive all dividends with respect to such shares, whether or not the shares have vested. Presently, these nonvested participating securities have an immaterial impact on diluted earnings per share. As of March 31, 2024, the total unrecognized compensation cost related to nonvested restricted stock awards was $10,971 with a weighted-average expense recognition period of 1.6 years.

The following summarizes the changes to United’s nonvested restricted common shares for the period ended March 31, 2024:

	Shares			Weighted-Average Grant Date Fair Value Per Share
Nonvested at January 1, 2024		333,932		$	37.75
Granted		183,908			34.36
Vested		(187,258	)		36.60
Forfeited		(5,215	)		36.48
Nonvested at March 31, 2024		325,367		$	36.51

Restricted Stock Units

Under the 2020 LTI Plan, United may grant restricted stock units (“RSUs”) to key employees. These awards help align the interests of these employees with the interests of the shareholders of United by providing economic value directly related to the performance of the Company. These RSU grants could be time-vested RSUs, performance-vested RSUs, or a combination of both. Currently, time-vested RSUs vest ratably over three years from the date of grant. Performance-vested RSUs cliff-vest after assessment of the Company’s performance over a period of three years. The number of performance-vested RSUs that vest is determined by two metrics measured relative to peers: Return on Average Tangible Common Equity (“ROATCE”) and Total Shareholder Return (“TSR”). Based on ASC Topic 718, the ROATCE comparison is considered a performance condition while the TSR comparison is considered a market condition. There will be no payout of the performance-vested awards if the threshold performance is not achieved. United communicates the specific threshold, target, and maximum performance-vested RSU awards and performance targets to the applicable key employees at the beginning of a performance period. Dividends are accrued but not paid in respect to the awards until the RSUs vest. The holder does not have the right to vote the shares during the time and performance periods. The value of the time-vested RSUs and the performance-vested, based on the performance condition, RSUs awarded is established as the fair market value of the stock at the time of the grant. The value of the performance-vested, based on the market condition, RSUs awarded is estimated through the use of a Monte Carlo valuation model as of the grant date. The Company recognizes expense on the RSUs in accordance with ASC Topic 718.

The following table summarizes the status of United’s nonvested RSUs during the first three months of 2024:

	Shares			Weighted-Average Grant Date Fair Value Per Share
Nonvested at January 1, 2024		363,502		$	37.53
Granted		254,592			32.80
Vested		(127,536	)		36.28
Forfeited or expired		(439	)		34.72
Nonvested at March 31, 2024		490,119		$	35.41

As of March 31, 2024, the total unrecognized compensation cost related to nonvested restricted stock units was $13,314 with a weighted-average expense recognition period of 2.0 years.

Variable Interest Entities

19. VARIABLE INTEREST ENTITIES

Variable interest entities (“VIEs”) are entities that either have a total equity investment that is insufficient to permit the entity to finance its activities without additional subordinated financial support or whose equity investors lack the characteristics of a controlling financial interest (i.e., ability to make significant decisions, through voting rights, right to receive the expected residual returns of the entity, and obligation to absorb the expected losses of the entity). VIEs can be structured as corporations, trusts, partnerships, or other legal entities. United’s business practices include relationships with certain VIEs. For United, the business purpose of these relationships primarily consists of funding activities in the form of issuing trust preferred securities.

United currently sponsors twenty statutory business trusts that were created for the purpose of raising funds that originally qualified for Tier I regulatory capital. As previously discussed, these trusts now are considered Tier II regulatory capital. These trusts, of which several were acquired through bank acquisitions, issued or participated in pools of trust preferred capital securities to third-party investors with the proceeds invested in junior subordinated debt securities of United. The Company, through a small capital contribution, owns 100% of the voting equity shares of each trust. The assets, liabilities, operations, and cash flows of each trust are solely related to the issuance, administration, and repayment of the preferred equity securities held by third-party investors. United fully and unconditionally guarantees the obligations of each trust and is obligated to redeem the junior subordinated debentures upon maturity.

United does not consolidate these trusts as it is not the primary beneficiary of these entities because United’s wholly owned and indirect wholly owned statutory trust subsidiaries do not have a controlling financial interest in the VIEs. A controlling financial interest is present when an enterprise has both the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and an obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE. The enterprise with a controlling financial interest, known as the primary beneficiary, consolidates the VIE. At March 31, 2024 and December 31, 2023, United’s investment (maximum exposure to loss) in these trusts were $11,876 and $11,751, respectively.

Information related to United’s statutory trusts is presented in the table below:

United, through its banking subsidiary, also makes limited partner equity investments in various low income housing and community development partnerships sponsored by independent third-parties. United invests in these partnerships to either realize tax credits on its consolidated federal income tax return or for purposes of earning a return on its investment. These partnerships are considered VIEs as the limited partners lack a controlling financial interest in the entities through their inability to make decisions that have a significant effect on the operations and success of the partnerships. United’s limited partner interests in these entities is immaterial; however, these partnerships are not consolidated as United is not deemed to be the primary beneficiary. At March 31, 2024 and December 31, 2023, United’s investment (maximum exposure to loss) in these low income housing and community development partnerships were $90,919 and $87,554, respectively, while related unfunded commitments were $65,039 and $63,539, respectively. As of March 31, 2024, United expects to recover its remaining investments through the use of the tax credits that are generated by the investments.

Accounting Policies [Abstract]

Operating and Reporting Segments

Operating and Reporting Segments

As of March 31, 2024, United’s business activities are confined to one operating segment, United Bank, and one reportable segment, community banking. As a community banking entity, United, through United Bank, offers a full range of products and services through various delivery channels. Included among the banking products and services offered are the acceptance of deposits in checking, savings, time and money market accounts; the making and servicing of personal, credit card, commercial, and floor plan loans; and the making of construction and real estate loans as well as the origination and sale of residential mortgages in the secondary market. Also offered are trust and brokerage services, safe deposit boxes, and wire transfers. United’s chief operating decision maker regularly reviews the operating results of United Bank in order to assess performance and make decisions about resource allocation. Previously, United had three operating segments: United Bank, George Mason Mortgage, LLC (“George Mason”) and Crescent Mortgage Company (“Crescent”), and two reporting segments: community banking and mortgage banking. However, during the first quarter of 2024, United consolidated the mortgage origination and sales business of George Mason and Crescent with that of United Bank. United previously exited the third-party origination (“TPO”) business during the fourth quarter of 2023.

The consolidated balance sheet as of December 31, 2023 has been extracted from the audited financial statements included in United’s 2023 Annual Report to Shareholders. The Notes to Consolidated Financial Statements appearing in United’s 2023 Annual Report on Form 10-K, which includes descriptions of significant accounting policies, should be read in conjunction with these interim financial statements. In the opinion of management, any adjustments necessary for a fair presentation of financial position and results of operations for the interim periods have been made. Such adjustments are of a normal and recurring nature.

The accompanying consolidated interim financial statements include the accounts of United and its wholly owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in the consolidated financial statements. Information is presented in these notes to the unaudited consolidated interim financial statements with dollars expressed in thousands, except per share or unless otherwise noted.

New Accounting Standards

New Accounting Standards

In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-09, “Improvements to Income Tax Disclosures.” ASU 2023-09 enhances annual income tax disclosures by requiring (1) consistent categories and greater disaggregation of information in the rate reconciliation and (2) income taxes paid disaggregated by jurisdiction. ASU 2023-09 also includes certain other amendments to improve the effectiveness of income tax disclosures. ASU 2023-09 is effective for public business entities for annual periods beginning after December 15, 2024. For entities other than public business entities, the amendments are effective for annual periods beginning after December 15, 2025. Entities are permitted to early adopt the standard for annual financial statements that have not yet been issued or made available for issuance. The adoption of ASU 2023-09 is not expected to have an impact on the Company’s financial condition or results of operations but could change certain disclosures in United’s SEC filings.

In November 2023, the FASB issued ASU 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures.” The amendments in ASU 2023-07 improve reportable segment disclosure requirements, mainly through enhanced disclosures about significant segment expenses. In addition, the amendments enhance interim disclosure requirements, clarify circumstances in which an entity can disclose multiple segment measures of profit or loss, provide new segment disclosure requirements for entities with a single reportable segment, and contain other disclosure requirements. The purpose of the amendments will enable investors to better understand an entity’s overall performance and assess potential future cash flows. ASU No. 2023-07 is effective for public business entities for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption of the amendment is permitted. The adoption of ASU 2023-07 is not expected to have an impact on the Company’s financial condition or results of operations but could change certain disclosures in United’s SEC filings starting with its 2024 Annual Report on Form 10-K.

In October 2023, the FASB issued ASU 2023-06, “Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative,” which adopts certain disclosure requirements referred by the SEC. For entities subject to the SEC’s existing disclosure requirements and for entities required to file or furnish financial statements with or to the SEC in preparation for the sale of or for purposes of issuing securities that are not subject to contractual restrictions on transfer, the effective date for each amendment will be the date on which the SEC’s removal of that related disclosure from Regulation S-X or Regulation S-K becomes effective, with early adoption prohibited. For all other entities, the amendments will be effective two years later. The adoption of ASU 2023-06 is not expected to have an impact on the Company’s financial condition or results of operations but could change certain disclosures in United’s SEC filings.

In August 2023, the FASB issued ASU 2023-05, “Business Combinations – Joint Venture Formations (Subtopic 805-60).” ASU 2023-05 requires a joint venture to apply a new basis of accounting at its formation date by valuing the net assets contributed at fair value for both business and asset transactions. The value of the net assets in total is then allocated to individual assets and liabilities by applying Topic 805 with certain exceptions. ASU 2023-05 requires certain disclosures to aid the user of the financial statements in understanding the implications of the joint venture formation. ASU 2023-05 is effective for joint venture formations with a formation date on or after January 1, 2025. The adoption of ASU 2023-05 is not expected to have an impact on the Company’s financial condition or results of operations.

In July 2023, the FASB issued ASU No. 2023-03, “Presentation of Financial Statements (Topic 205), Income Statement—Reporting Comprehensive Income (Topic 220), Distinguishing Liabilities from Equity (Topic 480), Equity (Topic 505), and Compensation—Stock Compensation (Topic 718): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 120, SEC Staff Announcement at the March 24, 2022 EITF Meeting, and Staff Accounting Bulletin Topic 6.B, Accounting Series Release 280—General Revision of Regulation S-X: Income or Loss Applicable to Common Stock.” ASU 2023-03 amends the ASC for SEC updates pursuant to SEC Staff Accounting Bulletin No. 120; SEC Staff Announcement at the March 24, 2022 Emerging Issues Task Force (“EITF”) Meeting; and Staff Accounting Bulletin Topic 6.B, Accounting Series Release 280 - General Revision of Regulation S-X: Income or Loss Applicable to Common Stock. These updates were immediately effective and did not have a significant impact on the Company’s financial statements.

In March 2023, the FASB issued Accounting ASU 2023-02, “Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method.” ASU 2023-02 permits reporting entities to elect to account for their tax equity investments, regardless of the tax credit program from which the income tax credits are received, using the proportional amortization method if certain conditions are met. The amendments in this ASU apply to all reporting entities that hold

tax equity investments that meet the conditions for and elect to account for them using the proportional amortization method or an investment in a low income housing tax credit (“LIHTC”) structure through a limited liability entity that is not accounted for using the proportional amortization method and to which certain LIHTC-specific guidance removed from Subtopic 323-740 has been applied. Additionally, the disclosure requirements apply to investments that generate income tax credits and other income tax benefits from a tax credit program for which the entity has elected to apply the proportional amortization method (including investments within that elected program that do not meet the conditions to apply the proportional amortization method). ASU 2023-02 was effective for United on January 1, 2024. The amendments in this update must be applied on either a modified retrospective or a retrospective basis except for LIHTC investments not accounted for using the proportional amortization method. At January 1, 2024, United chose not to elect to account for its tax equity investments using the proportional amortization method.

In December 2022, the FASB issued ASU 2022-06, “Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848.” ASU 2022-06 extends the period of time financial statement preparers can utilize the reference rate reform relief guidance. In 2020, the FASB issued ASU 2020-04 to provide temporary, optional expedients related to the accounting for contract modifications and hedging transactions as a result of the global markets’ anticipated transition away from the use of LIBOR and other interbank offered rates to alternative reference rates. At the time ASU 2020-04 was issued, the United Kingdom’s Financial Conduct Authority (“FCA”) had established the intent that it would no longer be necessary to persuade, or compel, banks to submit to LIBOR after December 31, 2021. As a result, the sunset provision was set for December 31, 2022; 12 months after the expected cessation date of all currencies and tenors of LIBOR. In March 2021, the FCA announced that the intended cessation date of LIBOR in the United States would be June 30, 2023, which has now taken effect as intended. Accordingly, ASU 2022-06 defers the expiration date of ASU 848 to December 31, 2024. United implemented a comprehensive project plan to execute the transition of its LIBOR-based financial instruments to alternative reference rates. United utilized the Secured Overnight Financing Rate (“SOFR”) and Prime as the preferred alternatives to LIBOR.

In June 2022, the FASB issued ASU 2022-03, “Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions.” ASU 2022-03 clarifies that a contractual restriction on the sale of an equity security is not considered part of the unit of account of the equity security and, therefore, is not considered in measuring fair value. ASU 2022-03 also clarifies that an entity cannot, as a separate unit of account, recognize and measure a contractual sale restriction and requires certain new disclosures for equity securities subject to contractual sale restrictions. ASU 2022-03 was effective for United on January 1, 2024. The adoption of ASU 2022-03 did not have a material impact on the Company’s financial condition or results of operations.
