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, 2026 and 2025 and for the three-month periods then ended have not been audited. The consolidated balance sheet as of December 31, 2025 has been extracted from the audited financial statements included in United’s 2025 Annual Report to Shareholders. The Notes to Consolidated Financial Statements appearing in United’s 2025 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, 2026, 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. New Accounting Standards In December 2025, the Financial Accounting Standards Board (“FASB”) released Accounting Standards Update (“ASU”) 2025-11, “Interim Reporting (Topic 270): Narrow-Scope Improvements.” ASU 2025-11 is intended to improve the navigability of the guidance in Accounting Standards Codification (“ASC”) Topic 270 and clarify when it applies. Under the amendments, an entity is subject to ASC Topic 270 if it provides “interim financial statements and notes in accordance with GAAP.” The ASU also addresses the form and content of such financial statements, adds lists to ASC Topic 270 of the interim disclosures required by all other Codification topics, and establishes a principle under which an entity must “disclose events since the end of the last annual reporting period that have a material impact on the entity.” ASU 2025-11 is effective for all public business entities for annual periods beginning after December 15, 2027, with early adoption permitted. The adoption of ASU 2025-11 is not expected to have a material impact on the Company’s financial condition or results of operations but could change certain disclosures in United’s SEC filings. 10 Table of Contents In November 2025, the FASB released ASU 2025-09, “Derivatives and Hedging (Topic 815): Hedge Accounting Improvements.” ASU 2025-09 amends certain aspects of the hedge accounting guidance in ASC Topic 815. In addition to addressing stakeholder concerns, the amendments are intended to more closely align hedge accounting with the economics of an entity’s risk management activities. ASU 2025-09 is effective for all public business entities for annual periods beginning after December 15, 2026, with early adoption permitted. The ASU 2025-09 guidance should be applied prospectively for all hedging relationships as of the date of adoption. Entities must disclose the nature of and reason for the change in accounting principle, as well as the method of applying the change, in both the interim reporting period and the annual reporting period in which they adopt the ASU. The adoption of ASU 2025-09 is not expected to have a material impact on the Company’s financial condition or results of operations. In November 2025, the FASB released ASU 2025-08, “Financial Instruments—Credit Losses (Topic 326): Purchased Loans.” ASU 2025-08 makes significant changes to the accounting for certain acquired seasoned loans subject to the current expected credit loss model (CECL). No changes were made to the existing models for originated assets, purchased credit deteriorated assets (PCD) or other acquired assets. Under the ASU 2025-08, the initial allowance for credit losses recorded upon the acquisition of loans in scope is recognized as an adjustment to the amortized cost basis of the loan–similar to the PCD model. For these loans, the “day-one” credit loss estimate does not impact earnings immediately but rather is amortized over time as an adjustment to interest income. Subsequent changes in the allowance for credit losses are reported in earnings within credit loss expense. ASU 2025-08 is effective for all business entities for annual periods beginning after December 15, 2026, with early adoption permitted. The Company is currently evaluating the impact the adoption of ASU 2025-08 may have on the Company’s financial condition or results of operations for subsequent acquisitions. In September 2025, the FASB released ASU 2025-06, “Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software.” ASU 2025-06 modernizes the accounting for internal-use software (the existing internal-use software guidance does not contemplate more current methods of software development). The amendments in ASU 2025-06 are limited and focused on the key challenge that entities face in applying FASB ASC Subtopic 350-40—applying that guidance to software that is developed using an incremental and iterative method. The amendments in ASU 2025-06 apply to all entities subject to the internal-use software guidance in FASB ASC Subtopic 350-40. The amendments also apply to all entities that account for website development costs in accordance with FASB ASC Subtopic 350-50, Intangibles— Goodwill and Other—Website Development Costs. ASU 2025-06 is effective for all business entities for annual periods beginning after December 15, 2027, with early adoption permitted. The adoption of ASU 2025-06 is not expected to have a material impact on the Company’s financial condition or results of operations. In July 2025, the FASB released ASU 2025-05, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets.” ASU 2025-05 amends ASC Subtopic 326-20 to provide a practical expedient for all entities and an accounting policy election for all entities, other than public business entities, that elect the practical expedient related to the estimation of expected credit losses for current accounts receivable and current contract assets that arise from transactions accounted for under ASC Topic 606, “Revenue from Contracts with Customers”. ASU 2025-05 addresses concerns from stakeholders that estimating expected credit losses can be costly and complex for such transactions. ASU 2025-05 was effective for all business entities for annual periods beginning after December 15, 2025, with early adoption permitted. The adoption of ASU 2025-05 did not have a material impact on the Company’s financial condition or results of operations. In May 2025, The FASB has released ASU 2025-03, “Business Combinations (Topic 805) and Consolidation (Topic 810): Determining the Accounting Acquirer in the Acquisition of a Variable Interest Entity.” ASU 2025-03 is based on an EITF Issue and revises the guidance in ASC Topic 805 to clarify that, in determining the accounting acquirer in “a business combination that is effected primarily by exchanging equity interests in which a VIE is acquired,” an entity would be required to consider the factors in ASC Subtopic 805-10-55-12 through 55-15. Previously, the accounting acquirer in such transactions was always the primary beneficiary. ASU 2025-03 is effective for all business entities for annual periods beginning after December 15, 2026. The adoption of ASU 2025-03 is not expected to have a material impact on the Company’s financial condition or results of operations. 11 Table of Contents In January 2025, the FASB issued ASU 2025-01, “Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40).” ASU 2025-01 revised the effective date of ASU 2024-03 to clarify that all public business entities are required to adopt the guidance in annual reporting periods beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027. Entities within the ASU’s scope are permitted to early adopt. The adoption of ASU 2025-01 is not expected to have a material impact on the Company’s financial condition or results of operations but could change certain disclosures in United’s SEC filings. In November 2024, the FASB issued Accounting Standards Update ASU 2024-04, “Induced Conversions of Convertible Debt Instruments.” ASU 2024-04 provides additional guidance on whether induced conversion or extinguishment accounting should be applied to certain settlements of convertible debt instruments that do not occur in accordance with the instruments’ preexisting terms. ASU 2024-04 requires entities to apply a preexisting contract approach. To qualify for induced conversion accounting under this approach, the inducement offer is required to preserve the form of consideration and result in an amount of consideration that is not less than that issuable pursuant to the preexisting conversion privileges. ASU 2024-04 clarifies how entities should assess the form and amount of consideration when applying this approach. ASU 2024-04 is effective for public business entities for annual periods beginning after December 15, 2025, with early adoption permitted, and can be adopted either on a prospective or retrospective basis. The adoption of ASU 2024-04 is not expected to have a material impact on the Company’s financial condition or results of operations. In November 2024, the FASB issued Accounting Standards Update ASU 2024-03, “Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses.” ASU 2024-03 requires disaggregated disclosure of income statement expenses for public business entities. ASU 2024-03 adds ASC Subtopic 220-40 to require a footnote disclosure about specific expenses by requiring public business entities to disaggregate, in a tabular presentation, each relevant expense caption on the face of the income statement that includes any of the following natural expenses: purchases of inventory, employee compensation, depreciation, intangible asset amortization, and depreciation, depletion, and amortization recognized as part of oil- and gas-producing activities or other types of depletion expenses. Certain other expenses and gains or losses that must be disclosed under existing U.S. GAAP, and that are recorded in a relevant expense caption, must be presented in the same tabular disclosure. ASU 2024-03 does not change or remove existing expense disclosure requirements; however, it may affect where that information appears in the footnote to the financial statements. ASU 2024-03 is effective for public business entities for annual periods beginning after December 15, 2026. However, the effective date was amended by ASU 2025-01 to clarify that all public business entities adopt ASU 2024-03 in the first annual reporting period beginning after December 15, 2026, and in interim periods within annual reporting periods beginning after December 15, 2027 Entities are permitted to early adopt the standard and apply retrospectively for annual financial statements that have not yet been issued or made available for issuance. The adoption of ASU 2024-03 is not expected to have a material impact on the Company’s financial condition or results of operations but could change certain disclosures in United’s SEC filings. 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 did not have an impact on the Company’s financial condition or results of operations. 12 Table of Contents 2.

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 $ 14,000 and $ 12,717 at March 31, 2026 and December 31, 2025, respectively, that is recorded in “Accrued interest receivable.” 13 Table of Contents The following is a summary of securities available for sale which were in an unrealized loss position at March 31, 2026 and December 31, 2025.

There were no gross realized gains and losses included in earnings on any sales and calls of available for sale securities for the three months ended March 31, 2026 and 2025. United recognizes any gains or losses on sales and calls of available for sale securities using the specific identification method. 14 Table of Contents At March 31, 2026, gross unrealized losses on available for sale securities were $ 226,446 on 870 securities of a total portfolio of 1,037 available for sale securities. Securities with the most significant gross unrealized losses at March 31, 2026 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, 2026 was the result of elevated 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 $ 569,145 at March 31, 2026. As of March 31, 2026, approximately 46 % 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, 2026. 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, 2026. 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 $ 143,756 on mortgage-backed securities at March 31, 2026. 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 $ 2,086,968 at March 31, 2026. Of the $ 2,086,968 amount, $ 413,080 was related to agency commercial mortgage-backed securities and $ 1,673,888 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, 2026. 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 $ 42,296 at March 31, 2026. Of the $ 42,296 , 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, 2026. Asset-backed securities As of March 31, 2026, United’s asset-backed securities portfolio had a total amortized cost balance of $ 204,171 . 100 % of the portfolio had at least one rating above investment grade as of March 31, 2026. Approximately 69 % 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 31 % of the portfolio relates to collateralized loan obligation securities that are all AAA rated. Upon reviewing this portfolio as of March 31, 2026, it was determined that none of the asset-backed securities had credit losses. 15 Table of Contents 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, 2026 consisted of $ 7,490 in investment grade bonds and $ 5,834 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 2026, it was determined that none of the single issue trust preferred securities had credit losses. Other corporate securities As of March 31, 2026, United’s other corporate securities portfolio had a total amortized cost balance of $ 232,746 . The majority of the portfolio consisted of debt issuances of corporations representing a variety of industries, including financial institutions. Of the $ 232,746 , 95 % had at least one rating above investment grade, 2 % 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, 2026. The amortized cost and estimated fair value of securities available for sale at March 31, 2026 and December 31, 2025 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, 2026 December 31, 2025 Estimated Estimated Amortized Fair Amortized Fair Cost Value Cost Value Due in one year or less $ 297,483 $ 296,964 $ 298,573 $ 298,193 Due after one year through five years 580,062 540,509 527,383 494,204 Due after five years through ten years 480,739 445,810 559,647 521,011 Due after ten years 2,072,405 1,928,789 1,879,257 1,746,044 Total $ 3,430,689 $ 3,212,072 $ 3,264,860 $ 3,059,452 Equity securities at fair value Equity securities consist mainly of equity securities of financial institutions, 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 $ 12,248 at March 31, 2026 and $ 34,760 at December 31, 2025. The decline in equity securities from December 31, 2025 was due mainly to the sale of equity securities totaling $ 26,646 in the first quarter of 2026. Three Months Ended March 31 2026 2025 Net gains recognized during the period on equity securities sold $ 2,296 $ 0 Unrealized gains recognized during the period on equity securities still held at period end 2 554 Unrealized losses recognized during the period on equity securities still held at period end ( 33 ) ( 33 ) Net gains recognized during the period $ 2,265 $ 521 16 Table of Contents Other investment securities During the first quarter of 2026, United evaluated all of its cost method investments to determine if certain events or changes in circumstances during the first quarter of 2026 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 $ 2,042,566 and $ 2,102,175 at March 31, 2026 and December 31, 2025, respectively. 3. LOANS AND LEASES Major classes of loans and leases are as follows: March 31, 2026 December 31, 2025 Commercial, financial and agricultural: Owner-occupied commercial real estate $ 2,140,233 $ 2,145,921 Nonowner-occupied commercial real estate 8,546,654 8,343,520 Other commercial 3,758,923 3,784,833 Total commercial, financial & agricultural 14,445,810 14,274,274 Residential real estate 6,115,055 6,098,262 Construction & land development 3,541,988 3,570,902 Consumer: Bankcard 9,227 9,686 Other consumer 762,659 767,496 Less: Unearned income ( 11,601 ) ( 11,498 ) Total gross loans $ 24,863,138 $ 24,709,122 The table above does not include loans held for sale of $ 29,235 and $ 31,277 at March 31, 2026 and December 31, 2025, 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 $ 47,215 and $ 42,441 at March 31, 2026 and December 31, 2025, 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. 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 17 Table of Contents 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: Age Analysis of Past Due Loans and Leases As of March 31, 2026 30-89 Days Past Due 90 Days or more Past Due Total Past Due Current & Other Total Financing Receivables 90 Days or More Past Due & Accruing Commercial real estate: Owner-occupied $ 5,323 $ 1,390 $ 6,713 $ 2,133,520 $ 2,140,233 $ 242 Nonowner-occupied 6,304 71,547 77,851 8,468,803 8,546,654 4,399 Other commercial 14,035 5,649 19,684 3,739,239 3,758,923 732 Residential real estate 23,470 21,189 44,659 6,070,396 6,115,055 5,357 Construction & land development 1,963 1,839 3,802 3,538,186 3,541,988 537 Consumer: Bankcard 33 31 64 9,163 9,227 31 Other consumer 10,170 1,189 11,359 751,300 762,659 366 Total $ 61,298 $ 102,834 $ 164,132 $ 24,710,607 $ 24,874,739 $ 11,664 Age Analysis of Past Due Loans and Leases As of December 31, 2025 30-89 Days Past Due 90 Days or more Past Due Total Past Due Current & Other Total Financing Receivables 90 Days or More Past Due & Accruing Commercial real estate: Owner-occupied $ 4,754 $ 1,830 $ 6,584 $ 2,139,337 $ 2,145,921 $ 81 Nonowner-occupied 7,598 71,038 78,636 8,264,884 8,343,520 0 Other commercial 2,490 6,569 9,059 3,775,774 3,784,833 591 Residential real estate 25,026 19,124 44,150 6,054,112 6,098,262 3,701 Construction & land development 1,508 1,301 2,809 3,568,093 3,570,902 0 Consumer: Bankcard 28 54 82 9,604 9,686 54 Other consumer 13,661 1,550 15,211 752,285 767,496 547 Total $ 55,065 $ 101,466 $ 156,531 $ 24,564,089 $ 24,720,620 $ 4,974 18 Table of Contents The following table sets forth United’s nonaccrual loans and leases, segregated by class of loans and leases: At March 31, 2026 At December 31, 2025 Nonaccruals With No Related Allowance for Credit Losses Nonaccruals With No Related Allowance for Credit Losses Commercial Real Estate: Owner-occupied $ 1,148 $ 1,148 $ 1,749 $ 1,749 Nonowner-occupied 67,148 67,148 71,038 71,038 Other Commercial 4,917 2,454 5,978 3,515 Residential Real Estate 15,832 15,832 15,423 15,423 Construction 1,302 1,302 1,301 1,301 Consumer: Bankcard 0 0 0 0 Other consumer 823 823 1,003 1,003 Total $ 91,170 $ 88,707 $ 96,492 $ 94,029 Interest income recognized on nonaccrual loans was insignificant during the three months ended March 31, 2026 and 2025. 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 2026 and 2025, 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.

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 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, 2026 and December 31, 2025: Collateral Dependent Loans and Leases At March 31, 2026 Residential Property Business Assets Land Commercial Property Other Total Commercial real estate: Owner-occupied $ 0 $ 0 $ 0 $ 3,975 $ 20,043 $ 24,018 Nonowner-occupied 5,316 0 0 73,605 31,485 110,406 Other commercial 0 12,309 0 4,865 3,091 20,265 Residential real estate 6,160 0 0 0 4 6,164 Construction & land development 1,421 0 798 0 1,354 3,573 Consumer: Bankcard 0 0 0 0 0 0 Other consumer 0 0 0 0 0 0 Total $ 12,897 $ 12,309 $ 798 $ 82,445 $ 55,977 $ 164,426 Collateral Dependent Loans and Leases At December 31, 2025 Residential Property Business Assets Land Commercial Property Other Total Commercial real estate: Owner-occupied $ 0 $ 0 $ 0 $ 3,094 $ 19,366 $ 22,460 Nonowner-occupied 6,830 0 0 84,786 38,761 130,377 Other commercial 0 4,005 0 4,893 3,174 12,072 Residential real estate 6,049 0 0 0 5 6,054 Construction & land development 250 0 849 0 1,170 2,269 Consumer: 21 Table of Contents Collateral Dependent Loans and Leases At December 31, 2025 Residential Property Business Assets Land Commercial Property Other Total Bankcard 0 0 0 0 0 0 Other consumer 0 0 0 0 0 0 Total $ 13,129 $ 4,005 $ 849 $ 92,773 $ 62,476 $ 173,232 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 $4,000 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. 22 Table of Contents 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. Loans originated in any year may be renewals of existing loans and not necessarily new loans.

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, 2026 and December 31, 2025, the recorded investment of consumer mortgage loans secured by residential real estate properties for which formal foreclosure proceedings are in process was $ 1,946 and $ 1,868 , 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. 26 Table of Contents 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 $ 93,656 and $ 95,960 at March 31, 2026 and December 31, 2025, 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, 2026 and December 31, 2025: Accrued Interest Receivable At March 31, 2026 At December 31, 2025 Commercial Real Estate: Owner-occupied $ 6,279 $ 6,922 Nonowner-occupied 38,858 37,086 Other Commercial 10,338 11,822 Residential Real Estate 21,646 21,643 Construction 14,197 16,046 Consumer: Bankcard 0 0 Other consumer 2,338 2,441 Total $ 93,656 $ 95,960 The following table represents the accrued interest receivables written off by reversing interest income for the three months ended March 31, 2026 and 2025: Accrued Interest Receivables Written Off by Reversing Interest Income Three Months Ended March 31 2026 2025 Commercial Real Estate: Owner-occupied $ 0 $ 27 Nonowner-occupied 4 12 Other Commercial 2 33 Residential Real Estate 120 224 Construction 0 44 Consumer: Bankcard 0 0 Other consumer 39 76 Total $ 165 $ 416 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 Table of Contents 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 $ 37,047 and $ 35,075 at March 31, 2026 and December 31, 2025, 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 loan and lease losses at March 31, 2026 was relatively flat from December 31, 2025, increasing $ 2,081 or less than 1 % from December 31, 2025. 28 Table of Contents The first quarter of 2026 qualitative adjustments include analyses of the following: • Current conditions – United considered the impact of changes in economic and business conditions; collateral values for dependent loans; past due, nonaccrual and adversely classified 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 improved slightly in the first quarter, from a projection of 2.30 % for 2026 as of mid-December 2025 to 2.40 % for 2026 as of mid-March with a projection of 2.30 % for 2027. The unemployment rate forecast remained the same in the first quarter with a projection of 4.40 % for 2026 as of mid-December 2025 and mid-March 2026 with a slightly lower projection of 4.30 % for 2027. • Greater risk of loss in the office portfolio due to continued hybrid and remote work that may be exacerbated by future economic conditions. • 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: Allowance for Loan and Lease Losses and Carrying Amount of Loans and Leases For the Three Months Ended March 31, 2026 Commercial Real Estate Other Commercial Residential Real Estate Construction & Land Development Bankcard Other Consumer Total Owner- occupied Nonowner- occupied Allowance for Loan and Lease Losses: Beginning balance $ 13,564 $ 96,716 $ 61,729 $ 53,949 $ 57,967 $ 889 $ 12,704 $ 297,518 Charge-offs 0 ( 3,864 ) ( 1,434 ) ( 275 ) 0 ( 61 ) ( 1,196 ) ( 6,830 ) Recoveries 16 1 578 51 0 5 484 1,135 Provision 63 8,892 1,500 ( 95 ) ( 4,090 ) 110 1,396 7,776 Ending balance $ 13,643 $ 101,745 $ 62,373 $ 53,630 $ 53,877 $ 943 $ 13,388 $ 299,599 29 Table of Contents Allowance for Loan and Lease Losses and Carrying Amount of Loans and Leases For the Year Ended December 31, 2025 Commercial Real Estate Other Commercial Residential Real Estate Construction & Land Development Bankcard Total Owner- occupied Nonowner- occupied Other Consumer Allowance for Loan and Lease Losses: Beginning balance $ 11,852 $ 74,522 $ 65,105 $ 46,373 $ 63,621 $ 891 $ 9,480 $ 271,844 Initial allowance for PCD loans (acquired during the period) 795 11,059 872 208 4,584 0 0 17,518 Charge-offs ( 228 ) ( 35,798 ) ( 5,424 ) ( 999 ) ( 408 ) ( 320 ) ( 7,735 ) ( 50,912 ) Recoveries 318 160 2,309 704 225 55 1,429 5,200 Provision 827 46,773 ( 1,133 ) 7,663 ( 10,055 ) 263 9,530 53,868 Ending balance $ 13,564 $ 96,716 $ 61,729 $ 53,949 $ 57,967 $ 889 $ 12,704 $ 297,518 6.

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, 2026 March 31, 2025 Operating lease cost Net occupancy expense $ 5,086 $ 4,900 Sublease income Net occupancy expense ( 52 ) ( 50 ) Net lease cost $ 5,034 $ 4,850 Supplemental balance sheet information related to leases was as follows: Classification March 31, 2026 December 31, 2025 Operating lease right-of-use assets Operating lease right-of-use assets $ 87,841 $ 89,312 Operating lease liabilities Operating lease liabilities $ 93,921 $ 95,392 Other information related to leases was as follows: March 31, 2026 Weighted-average remaining lease term: Operating leases 7.46 years Weighted-average discount rate: Operating leases 3.64 % 31 Table of Contents Supplemental cash flow information related to leases was as follows: Three Months Ended March 31, 2026 March 31, 2025 Cash paid for amounts in the measurement of lease liabilities: Operating cash flows from operating leases $ 5,087 $ 4,872 ROU assets obtained in the exchange for lease liabilities 2,374 3,853 Maturities of lease liabilities by year and in the aggregate, under operating leases with initial or remaining terms of one year or more, for years subsequent to December 31, 2025, consists of the following as of March 31, 2026: Year Amount 2026 $ 14,211 2027 18,012 2028 15,732 2029 13,490 2030 11,175 Thereafter 35,817 Total lease payments 108,437 Less: imputed interest ( 14,516 ) Total $ 93,921 8. SHORT-TERM BORROWINGS At March 31, 2026 and December 31, 2025, short-term borrowings were as follows: As of March 31, 2026 As of December 31, 2025 Federal funds purchased $ 0 $ 0 Securities sold under agreements to repurchase 166,175 198,573 Total short-term borrowings $ 166,175 $ 198,573 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, 2026, United had no outstanding balance under this credit. 9. 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, 2026, United had an unused borrowing amount of approximately $ 9,236,038 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. 32 Table of Contents At March 31, 2026, a $ 250,000 FHLB advance with a weighted-average contractual interest rate of 3.82 % and a weighted-average effective interest rate of 0.59 % is scheduled to mature in 2026. The weighted-average effective rate considers the effect of any interest rate swaps designated as cash flow hedges outstanding at March 31, 2026 to manage interest rate risk on its long-term debt. At March 31, 2026, 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, 2026 and December 31, 2025, the outstanding balance of the Debentures was $ 282,216 and $ 281,817 , 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 or the fixed-to-floating rate subordinated notes as Tier 1 capital, but rather the Capital Securities and the fixed-to-floating rate subordinated notes are included as a component of United’s Tier 2 capital. United can include the Capital Securities and the fixed-to-floating rate subordinated notes in its Tier 2 capital on a permanent basis. 10. 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 $ 6,796,307 and $ 6,408,827 of loan commitments outstanding as of March 31, 2026 and December 31, 2025, respectively, approximately 31% of which contractually expire within one year . 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 33 Table of Contents intended between the customer and a third party. As of March 31, 2026 and December 31, 2025, United had $ 2,761 and $ 2,762 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 $ 170,105 and $ 166,885 as of March 31, 2026 and December 31, 2025, 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, 2026 and December 31, 2025. 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. 11. 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. 34 Table of Contents 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. United holds an interest rate swap derivative with a notional amount of $ 250,000 . The derivatives is designated as a cash flow hedge and is intended to hedge the changes in cash flows associated with floating rate FHLB borrowings. As of March 31, 2026, 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 $ 7,922 will be reclassified from AOCI as a decrease to interest expense over the next 12-months following March 31, 2026 related to the cash flow hedges. As of March 31, 2026, the maximum length of time over which forecasted transactions are hedged is five 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 $ 250,000 for asset derivatives as of March 31, 2026. 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 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 released 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. 35 Table of Contents The following tables disclose the derivative instruments’ location on the Company’s Consolidated Balance Sheets and the notional amount and fair value of those instruments at March 31, 2026 and December 31, 2025.

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. The effect on net income of United’s derivative financial instruments in its unaudited Consolidated Statements of Income for the three months ended March 31, 2026 and 2025 is presented as follows: Three Months Ended Income Statement Location March 31, 2026 March 31, 2025 Derivatives in hedging relationships Fair Value Hedges: Interest rate swap contracts Interest and fees on loans $ 2 $ ( 2 ) Cash flow Hedges: Interest rate swap contracts Interest on long-term borrowings 2,019 2,452 Total derivatives in hedging relationships $ 2,021 $ 2,450 Derivatives not designated as hedging instruments Forward loan sales commitments Income from Mortgage Banking Activities $ ( 33 ) $ 25 TBA mortgage-backed securities Income from Mortgage Banking Activities 481 ( 438 ) Interest rate lock commitments Income from Mortgage Banking Activities 348 335 Total derivatives not designated as hedging instruments $ 796 $ ( 78 ) Total derivatives $ 2,817 $ 2,372 For the three months ended March 31, 2026 and 2025, 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. 12. FAIR VALUE MEASUREMENTS United determines the fair values of its financial instruments based on the fair value hierarchy established in ASC Topic 820, “Fair Value Measurement,” 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. 37 Table of Contents 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, 2026, 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, 2026. 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. 38 Table of Contents 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, 2026, the range of historical sales prices increased the investor’s indicated pricing by a range of 0.006 % to 0.622 % with a weighted average increase of 0.207 %. 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 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 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 adjusted for the Company’s actual sales experience versus the investor’s indicated pricing (“Level 3”). 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”) 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, 2026, the range of historical sales prices increased the investor’s indicated pricing by a range of 0.006 % to 0.622 % with a weighted average increase of 0.207 %. For derivatives that are not designated in a hedge relationship, 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. 39 Table of Contents The following tables present the balances of financial assets and liabilities measured at fair value on a recurring basis as of March 31, 2026 and December 31, 2025, 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. 43 Table of Contents 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, 2025. 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. Other than those intangible assets recorded in the acquisition of Piedmont in the first quarter of 2025, no other fair value measurement of intangible assets was made during the first three months of 2026 and 2025. The following table summarizes United’s financial assets that were measured at fair value on a nonrecurring basis during the period: Description Fair Value at March 31, 2026 Balance as of March 31, 2026 Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) YTD Gains (Losses) Assets Individually assessed loans $ 45,875 $ 0 $ 44,289 $ 1,586 $ ( 1,730 ) OREO 10,390 0 10,390 0 ( 37 ) Description Fair Value at December 31, 2025 Balance as of December 31, 2025 Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) YTD Gains (Losses) Assets Individually assessed loans $ 51,485 $ 0 $ 49,870 $ 1,615 $ 1,172 OREO 8,857 0 8,857 0 0 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 as well as investment tax credits that do not have readily determinable fair values and are carried at cost. 44 Table of Contents 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: Fair Value Measurements Carrying Amount Fair Value Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) March 31, 2026 Cash and cash equivalents $ 2,305,034 $ 2,305,034 $ 0 $ 2,305,034 $ 0 Securities available for sale 3,212,072 3,212,072 4,597 3,207,475 0 Securities held to maturity 1,004 1,020 0 0 1,020 Equity securities 12,248 12,248 12,248 0 0 Other securities 305,244 289,982 0 0 289,982 Loans held for sale 29,235 29,235 0 0 29,235 Net loans 24,563,539 24,570,286 0 0 24,570,286 Derivative financial assets 1,384 1,384 0 350 1,034 Deposits 27,120,883 27,086,282 0 27,086,282 0 Short-term borrowings 166,175 166,175 0 166,175 0 Long-term borrowings 532,216 530,427 0 530,427 0 Derivative financial liabilities 19 19 0 0 19 45 Table of Contents Fair Value Measurements Carrying Amount Fair Value Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) December 31, 2025 Cash and cash equivalents $ 2,542,250 $ 2,542,250 $ 0 $ 2,542,250 $ 0 Securities available for sale 3,059,452 3,059,452 4,678 3,054,774 0 Securities held to maturity 1,004 1,020 0 0 1,020 Equity securities 34,760 34,760 29,356 5,404 0 Other securities 305,184 289,925 0 0 289,925 Loans held for sale 31,277 31,277 0 0 31,277 Net loans 24,411,604 24,432,980 0 0 24,432,980 Derivative financial assets 789 789 0 316 473 Deposits 27,060,939 27,031,873 0 27,031,873 0 Short-term borrowings 198,573 198,573 0 198,573 0 Long-term borrowings 531,817 524,281 0 524,281 0 Derivative financial liabilities 70 70 0 70 0 13. STOCK BASED COMPENSATION On May 14, 2025, United’s shareholders approved the 2025 Equity Incentive Plan (“2025 EIP”), becoming effective on that date. The 2025 EIP replaced United’s 2020 Long-Term Incentive Plan (“2020 LTI Plan”). An award granted under the 2025 EIP may consist of stock options, stock appreciation rights (“SARs”), restricted stock, restricted stock units, performance based stock awards, dividend equivalent rights and other equity-based or equity-related awards. 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 2025 EIP is 3,000,000 . The 2025 EIP will be administered by the Compensation and Human Capital Committee of the Board (the “Committee”). Awards are subject to a minimum vesting schedule of at least twelve months following the date of grant of such award, subject to accelerated vesting on certain events, including a change in control, and 5 % of the shares available for grant under the 2025 EIP may be granted with a shorter minimum vesting period. Awards under the 2025 EIP will be subject to the terms of the Company’s Compensation Recoupment Policy and any other clawback or recapture policy that the Company may adopt from time to time and, in accordance with such policy, may be subject to the requirement that the awards be repaid to the Company after they have been distributed to the grantee. A Form S-8 was filed on May 30, 2025 with the Securities and Exchange Commission to register all the shares available for issuance under the 2025 EIP Plan. During the first three months of 2026, a total of 155,135 shares of restricted stock and 226,556 of restricted stock units were granted under the 2025 EIP. No stock options were granted under the 2025 EIP during the first three months of 2026. Compensation expense of $ 3,214 and $ 2,875 related to the all share-based grants and awards under United’s Long-Term Incentive Plans was incurred for the first quarter of 2026 and 2025, respectively. Compensation expense was included in employee compensation in the unaudited Consolidated Statements of Income. Stock Options During the first quarter of 2026, no stock option awards were granted under the 2025 EIP. United does have options outstanding from various plans (the “Prior Plans”) under which stock options were granted; however, no 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 Prior Plans is ten ( 10 ) years. 46 Table of Contents A summary of activity under United’s stock option plans as of March 31, 2026, and the changes during the first three months of 2026 are presented below: Weighted Average Shares Aggregate Intrinsic Value Remaining Contractual Term (Yrs.) Exercise Price Outstanding at January 1, 2026 909,516 $ 36.78 Exercised ( 70,904 ) 30.05 Forfeited or expired ( 6,351 ) 36.43 Outstanding at March 31, 2026 832,261 $ 4,262 2.4 $ 37.35 Exercisable at March 31, 2026 832,261 $ 4,262 2.4 $ 37.35 During the three months ended March 31, 2026 and 2025, 70,904 and 9,816 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, 2026 and 2025 were issued from authorized and unissued stock. The total intrinsic value of options exercised under the Plans during the three months ended March 31, 2026 and 2025 was $ 930 and $ 55 , respectively. As of March 31, 2026, there was no unrecognized compensation cost related to nonvested stock option awards. Restricted Stock During the first quarter of 2026, restricted stock awards totaling 155,135 shares were granted under the 2025 EIP. Under the 2025 EIP, recipients of restricted stock will have the right to vote all shares subject to such grant, whether or not the shares have vested, but any dividends paid upon any restricted stock will be retained by the Company during the period of restriction, and will be paid to the relevant grantee (without interest) when the restricted stock vests and will revert back to the Company if for any reason the restricted stock upon which such dividends were paid is forfeited by the grantee prior to vesting. United also has unvested restricted stock awards granted to key employees and non-employee directors of the Company under the 2020 LTI Plan. Shares of restricted stock granted under the 2020 LTI Plan to participants were scheduled to vest no sooner than 1/3 per year over the first three anniversaries of the award. Recipients of shares of restricted stock under the 2020 LTI Plan did not pay any consideration to United for the shares, had the right to vote all shares subject to such grant and received 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, 2026, the total unrecognized compensation cost related to nonvested restricted stock awards was $ 12,441 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, 2026: Shares Weighted-Average Grant Date Fair Value Per Share Nonvested at January 1, 2026 325,427 $ 36.52 Granted 155,135 44.07 Vested ( 154,322 ) 37.09 Forfeited ( 2,236 ) 37.32 Nonvested at March 31, 2026 324,004 $ 39.86 47 Table of Contents Restricted Stock Units During the first quarter of 2026, restricted stock units (“RSUs”) totaling 226,556 were granted to key employees of the Company under the 2025 EIP. These RSUs awarded 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. United also has unvested RSUs granted under the 2020 LTI Plan. RSUs granted under these two plans are 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 outstanding as of March 31, 2026 that will vest in the future 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, “Compensation – Stock Compensation,” 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. Dividend equivalents 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 until shares of common stock are delivered in respect of vested RSUs. 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 changes to United’s nonvested RSUs during the first three months of 2026: Shares Weighted-Average Grant Date Fair Value Per Share Nonvested at January 1, 2026 595,485 $ 35.28 Granted 226,556 47.83 Vested ( 157,695 ) 38.24 Forfeited or expired ( 28,880 ) 39.89 Nonvested at March 31, 2026 635,466 $ 38.81 As of March 31, 2026, the total unrecognized compensation cost related to nonvested restricted stock units was $ 18,378 with a weighted-average expense recognition period of 1.8 years. 14. 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 2026 and 2025. Included in accumulated other comprehensive income at December 31, 2025 are unrecognized actuarial losses of $ 10,725 that have not yet been recognized in net periodic pension cost. Net periodic pension costs, except for service cost, are recognized in employee benefits on the consolidated statements of income. Service cost is recognized in employee compensation. 48 Table of Contents Net periodic pension cost for the three months ended March 31, 2026 and 2025 included the following components: Three Months Ended March 31 2026 2025 Service cost $ 332 $ 344 Interest cost 1,744 1,815 Expected return on plan assets ( 2,866 ) ( 2,721 ) Recognized net actuarial loss 0 0 Net periodic pension (benefit) cost $ ( 790 ) $ ( 562 ) Weighted-Average Assumptions: Discount Rate 5.66 % 5.76 % Expected return on assets 6.00 % 6.15 % Rate of Compensation Increase (prior to age 40) 6.00 % 6.00 % Rate of Compensation Increase (ages 40-49) 5.50 % 5.50 % Rate of Compensation Increase (ages 50-54) 5.00 % 5.00 % Rate of Compensation Increase (ages 55-64) 4.00 % 4.00 % Rate of Compensation Increase (otherwise) 3.00 % 3.00 % 15. INCOME TAXES United records a liability for uncertain income tax positions based on a recognition threshold of more-likely-than-not, and a measurement attribute for all tax positions taken on a tax return, in order for those tax positions to be recognized in the financial statements. As of March 31, 2026, no interest was accrued related to uncertain tax positions as compared to $ 677 as of March 31, 2025. United accounts for interest and penalties related to uncertain tax positions as part of its provision for federal and state income taxes. United is currently open to audit under the statute of limitations by the Internal Revenue Service for the years ended December 31, 2022, 2023 and 2024 and certain State Taxing authorities for the years ended December 31, 2022 through 2024. United’s effective tax rate was 20.38 % for the first quarter of 2026 and 21.16 % for the first quarter of 2025. 16.

EARNINGS PER SHARE The reconciliation of the numerator and denominator of basic earnings per share with that of diluted earnings per share is presented as follows : Three Months Ended March 31 2026 2025 Distributed earnings allocated to common stock $ 53,484 $ 53,510 Undistributed earnings allocated to common stock 70,527 30,613 Net earnings allocated to common shareholders $ 124,011 $ 84,123 Average common shares outstanding 139,566,209 142,330,694 Common stock equivalents 525,987 367,424 Average diluted shares outstanding 140,092,196 142,698,118 Earnings per basic common share $ 0.89 $ 0.59 Earnings per diluted common share $ 0.89 $ 0.59 Antidilutive stock options and restricted stock outstanding of 607,649 for the three months ended March 31, 2026 were excluded from the earnings per diluted common share calculation as compared to 567,715 for the three months ended March 31, 2025. 18. 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. As defined in applicable accounting standards, VIEs are entities that lack one or more of the characteristics of a voting interest entity. A controlling financial interest in a VIE 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. United’s wholly owned and indirect wholly owned statutory trust subsidiaries are VIEs for which United is not the primary beneficiary. Accordingly, its accounts are not included in United’s consolidated financial statements. At March 31, 2026 and December 31, 2025, United’s investment (maximum exposure to loss) in these trusts were $ 12,775 and $ 12,686 , respectively. 51 Table of Contents Information related to United’s statutory trusts is presented in the table below: Description Issuance Date Amount of Capital Securities Issued Stated Interest Rate (1) Maturity Date United Statutory Trust III December 17, 2003 $ 20,000 3-month CME Term SOFR + 2.85% December 17, 2033 United Statutory Trust IV December 19, 2003 $ 25,000 3-month CME Term SOFR + 2.85% January 23, 2034 United Statutory Trust V July 12, 2007 $ 50,000 3-month CME Term SOFR + 1.55% October 1, 2037 United Statutory Trust VI September 20, 2007 $ 30,000 3-month CME Term SOFR + 1.30% December 15, 2037 Premier Statutory Trust II September 25, 2003 $ 6,000 3-month CME Term SOFR + 3.10% October 8, 2033 Premier Statutory Trust III May 16, 2005 $ 8,000 3-month CME Term SOFR + 1.74% June 15, 2035 Premier Statutory Trust IV June 20, 2006 $ 14,000 3-month CME Term SOFR + 1.55% September 23, 2036 Premier Statutory Trust V December 14, 2006 $ 10,000 3-month CME Term SOFR + 1.61% March 1, 2037 Centra Statutory Trust I September 20, 2004 $ 10,000 3-month CME Term SOFR + 2.29% September 20, 2034 Centra Statutory Trust II June 15, 2006 $ 10,000 3-month CME Term SOFR + 1.65% July 7, 2036 VCBI Capital Trust II December 19, 2002 $ 15,000 6-month CME Term SOFR + 3.30% December 19, 2032 VCBI Capital Trust III December 20, 2005 $ 25,000 3-month CME Term SOFR + 1.42% February 23, 2036 Cardinal Statutory Trust I July 27, 2004 $ 20,000 3-month CME Term SOFR + 2.40% September 15, 2034 UFBC Capital Trust I December 30, 2004 $ 5,000 3-month CME Term SOFR + 2.10% March 15, 2035 Carolina Financial Capital Trust I December 19, 2002 $ 5,000 Prime + 0.50% December 31, 2032 Carolina Financial Capital Trust II November 5, 2003 $ 10,000 3-month CME Term SOFR + 3.05% January 7, 2034 Greer Capital Trust I October 12, 2004 $ 6,000 3-month CME Term SOFR + 2.20% October 18, 2034 Greer Capital Trust II December 28, 2006 $ 5,000 3-month CME Term SOFR + 1.73% January 30, 2037 First South Preferred Trust I September 26, 2003 $ 10,000 3-month CME Term SOFR + 2.95% September 30, 2033 BOE Statutory Trust I December 12, 2003 $ 4,000 3-month CME Term SOFR + 3.00% December 12, 2033 (1) The 3-month CME Term SOFR rates have a spread adjustment of 0.26161% and the 6-month CME Term SOFR rate has a spread adjustment of 0.42826%. 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. These partnerships are not consolidated as United is not deemed to be the primary beneficiary. At March 31, 2026 and December 31, 2025, United’s investment (maximum exposure to loss) in these low income housing and community development partnerships were $ 130,924 and $ 129,861 , respectively, while related unfunded commitments were $ 96,038 and $ 103,184 respectively. The total amount of these unfunded commitments in low income housing, community development and other partnerships at March 31, 2026 and December 31, 2025 includes $ 5,000 to a related interest of a director of the Company. As of March 31, 2026, United expects to recover its remaining investments through the use of the tax credits that are generated by the investments. 19. SEGMENT INFORMATION United operates in one reportable segment, community banking. Through its community banking segment, United 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. The community banking segment derives revenues mainly from interest income on loans to customers, investment securities held and other short-term investments in addition to fees and income derived related to the services listed above. 52 Table of Contents The accounting policies of the community banking segment are the same as those described in the summary of significant accounting policies. United’s chief operating decision maker (“CODM”) is its chief executive officer who maintains responsibility for the day-to-day management of the Company including regularly reviewing the operating results of the community banking segment in order to assess performance and make decisions about resource allocation based on net income that also is reported on the income statement as consolidated net income. The measure of community banking segment assets is reported on the Consolidated Balance Sheets as total assets. The CODM uses net income to evaluate income generated from segment assets (return on assets) in deciding whether to reinvest profits into the community banking segment or into other parts of the entity, such as for acquisitions or to pay dividends. Net income is used to monitor budget versus actual results as well as comparing to prior year’s results. The comparative analysis along with the monitoring of budgeted versus actual results are used in assessing performance of the segment. Information about the community banking segment for the three months ended March 31, 2026 and 2025 is as follows: For the Three Months Ended March 31 2026 2025 Total Assets $ 33,705,380 $ 32,788,494 Net interest income $ 282,515 $ 260,055 Provision for credit losses 7,776 29,103 Other income 34,063 29,554 Other expense Employee compensation 63,493 60,866 Employee benefits 15,980 13,291 Net occupancy expense 13,013 12,601 OREO expense 475 22 Net gains on the sales of OREO properties 0 ( 11 ) Equipment expense 8,740 8,582 Data processing expense 7,001 8,455 Bankcard processing expense 623 600 FDIC insurance expense 4,476 4,728 Other segment expense (a) 39,013 44,439 Total other expense 152,814 153,573 Income before income taxes 155,988 106,933 Income taxes 31,788 22,627 Segment net income 124,200 84,306 Reconciliation of profit or loss Adjustments and reconciling items 0 0 Consolidated net income $ 124,200 $ 84,306 (a) Other segment expense includes legal, consulting and other professional services expense, franchise and other taxes not on income, expense for reserve on lending-related commitments, ATM expenses, marketing expense, core deposits amortization, and other general operating expenses. 53 Table of Contents
