SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Overview USCB Financial Holdings, Inc., a Florida corporation incorporated in 2021, is a bank holding company with one direct wholly owned subsidiary, U.S. Century Bank (the “Bank”), together referred to as “the Company”. The Bank, established in 2002, is a Florida state-chartered, non-member financial institution providing financial services through its banking centers located in South Florida. The Bank owns a subsidiary, Florida Peninsula Title LLC, that offers our clients title insurance policies for real estate transactions closed at the Bank. Licensed in the State of Florida and approved by the Department of Insurance Regulation, Florida Peninsula Title LLC began operations in 2021. Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared in accordance with instructions to Form 10-Q and do not include all the information and footnotes required by U.S. generally accepted accounting principles (“U.S. GAAP”) for complete financial statements. All adjustments consisting of normally recurring accruals that, in the opinion of management, are necessary for a fair presentation of the financial position and results of operations for the periods presented have been included. These unaudited consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and related notes appearing in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025. Principles of Consolidation The Company consolidates entities in which it has a controlling financial interest. Intercompany transactions and balances are eliminated in consolidation. Use of Estimates To prepare consolidated financial statements in conformity with U.S. GAAP, management makes estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in the consolidated financial statements. The most significant estimate impacting the Company’s consolidated financial statements is the allowance for credit losses (“ACL”). Reclassifications Certain amounts in prior period consolidated financial statements have been reclassified to conform to the current presentation. Reclassifications had no impact on prior period net income or stockholders’ equity. Recently Issued Accounting Standards There were no recently issued accounting standards adopted or issued during the period that are expected to have a material impact on the Company’s consolidated financial statements.

The unrealized gain or loss at the date of transfer is retained in accumulated other comprehensive loss (“AOCL”) and in the carrying value of the HTM securities and there is no impact to net income. Table of Contents USCB FINANCIAL HOLDINGS, INC. Notes to the Consolidated Financial Statements - Unaudited 11 USCB Financial Holdings, Inc. Q2 2026 Form 10-Q Such amounts are amortized over the remaining life of the security. The Company made two transfers from AFS to HTM portfolios in 2022. During the quarter ended June 30, 2026, there were no investment securities that were transferred from AFS to HTM. For the three months ended June 30, 2026, total amortization out of AOCL for net unrealized losses on securities transferred in 2022 from AFS to HTM was $ 99 thousand and $ 67 thousand for the three months ended June 30, 2025. At June 30, 2026, the fair value of the transferred securities was $ 83.4 million and the balance of the remaining unamortized loss was $ 8.8 million. The measurement of expected credit losses under the current expected credit loss (“CECL”) methodology is applicable to financial assets measured at amortized cost, including loan receivables and HTM debt securities. CECL requires a loss reserve for securities classified as HTM. The reserve should reflect historical credit performance as well as the impact of projected economic forecasts. For U.S. Government bonds and U.S. Agency issued bonds classified as HTM, the explicit guarantee of the U.S. Government is sufficient to conclude that an allowance for credit loss reserve is not required. The reserve requirement is for three primary assets groups: municipal bonds, corporate bonds, and non- agency securitizations. The Company calculates quarterly the loss reserve utilizing Moody’s ImpairmentStudio. The CECL measurement for investment securities incorporates historical data, containing defaults and recoveries information, and Moody’s baseline economic forecast. The solution uses the probability of default/loss given default (“PD/LGD”) approach. PD represents the likelihood a borrower will default. Within the Moody’s model, this is determined using historical default data, adjusted for the current economic environment. LGD projects the expected loss if a borrower were to default. The Company monitors the credit quality of HTM securities through the use of credit ratings. Credit ratings are monitored by the Company on at least a quarterly basis. As of June 30, 2026 and December 31, 2025, all HTM securities held by the Company were rated investment grade. At June 30, 2026, the Company's HTM securities portfolio consisted entirely of U.S. government and U.S. agency- issued bonds and mortgage-backed securities with an amortized cost of $ 136.1 million. Due to the explicit or implicit guarantees associated with these securities, management determined that no ACL was required as of June 30, 2026. The Company utilizes a PD/LGD methodology to estimate expected credit losses for HTM securities exposed to non-government credit risk. As of December 31, 2025, the ACL for HTM securities was $ 2 thousand. The carrying value of HTM securities represents amortized cost less the related ACL. The Company’s investment portfolio includes AFS debt securities, which are carried at fair value with unrealized gains and losses recognized in AOCL, net of applicable taxes. The Company evaluates whether the declines in fair value are attributable to credit losses or other factors like interest rate risk, using both quantitative and qualitative analyses, including company performance analysis, review of credit ratings, bond vintage, remaining payment terms, prepayment speeds and analysis of macro-economic conditions. When the fair value of an AFS security is less than its amortized cost and the decline is attributable to credit-related factors, an ACL is recorded. As a result of this evaluation, the Company concluded that no allowance was required on AFS securities as of June 30, 2026 and as of December 31, 2025.

Municipal bonds are of high credit quality, and the observed declines in fair value are not attributable to a deterioration in the creditworthiness. Similarly, the decrease in fair value of bank subordinated debt securities is primarily driven by changes in market interest rates rather than credit concerns. Based on management’s evaluation of these factors, management believes that the unrealized losses on these debt securities are attributable to fluctuations in market spreads and interest rate movements, rather than adverse changes in the underlying credit quality of the issuers. The Company does not intend to sell the investments before recovery of its amortized cost basis, which may be at maturity, and it is more likely than not that the Company will not be required to sell the securities before maturity. Gains and losses on the sale of securities are recorded on the trade date and are determined on the specific identification basis.

Allowance for Credit Losses In general, the Company utilizes the Discounted Cash Flow (“DCF”) method or the Weighted-Average Remaining Maturity (“WARM”) methodology to estimate the quantitative portion of the ACL for loan pools. The DCF method uses a loss driver analysis (“LDA”) and DCF analysis. Management engaged advisors and consultants with expertise in CECL model development to assist in development of a LDA based on regression models and supportable forecast. Peer group data obtained from FFIEC Call Report filings is used to inform regression analyses to quantify the impact of reasonable and supportable forecasts in projective models. Economic forecasts applied to regression models to estimate probability of default for loan receivables use at least one of the following economic indicators: civilian unemployment rate (national), real gross domestic product growth (national GDP) or the House Price Index (“HPI”). For each of the segments in which the WARM methodology is used, the long-term average loss rate is calculated and applied on a quarterly basis for the remaining life of the pool. Adjustments for economic expectations are made through qualitative factors. Qualitative factors (“Q-Factors”) used in the ACL methodology include: • Changes in lending policies, procedures, and strategies • Changes in international, national, regional, and local economic conditions • Changes in nature and volume of the portfolio • Changes in the volume and severity of past due loans and other similar conditions • Concentration risk • Changes in the value of underlying collateral Table of Contents USCB FINANCIAL HOLDINGS, INC.

Internal credit risk grades are evaluated periodically. The Company's internally assigned credit risk grades are as follows: Pass – Loans indicate different levels of satisfactory financial condition and performance. Special Mention – Loans classified as special mention have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the institution’s credit position at some future date. Table of Contents USCB FINANCIAL HOLDINGS, INC. Notes to the Consolidated Financial Statements - Unaudited 16 USCB Financial Holdings, Inc. Q2 2026 Form 10-Q Substandard – Loans classified as substandard are inadequately protected by the current net worth and paying capacity of the obligator or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected. Doubtful – Loans classified as doubtful have all the weaknesses inherent in those classified at substandard, with the added characteristic that the weaknesses make collection or liquidation in full on the basis of currently existing facts, conditions, and values, highly questionable and improbable. Loss – Loans classified as loss are considered uncollectible.

LEASES The Company leases certain banking facilities and office space under non-cancelable operating lease agreements. During the six months ended June 30, 2026, the Company exercised renewal options and modified certain lease arrangements, including extensions of the Coral Gables branch and Doral branch/headquarters leases for additional five - year terms. These lease modifications resulted in the remeasurement of operating lease liabilities and corresponding right- of-use assets. Operating lease right-of-use assets and lease liabilities totaled $ 12.6 million at June 30, 2026, compared to $ 5.5 million at December 31, 2025. The lease modifications were measured using an incremental borrowing rate of 4.27 %. The Company’s incremental borrowing rate is based on the FHLB advances rate matching or nearing the lease term. There were no material changes to the Company's lease accounting policies from those disclosed in Note 4, Leases, included in the Annual Report on Form 10-K for the year ended December 31, 2025. 5. INCOME TAXES The Company’s income tax expense is presented in the following table for the periods indicated (in thousands): Six Months Ended June 30, 2026 2025 Pre-tax income: Domestic $ 24,400 $ 20,837 Total pre-tax income $ 24,400 $ 20,837 Current tax expense: Federal $ 4,745 $ - State 58 - Total current 4,803 - Deferred tax expense: Federal 140 3,948 State 1,028 1,091 Deferred income tax expense 1,168 5,039 Total income tax expense $ 5,971 $ 5,039 The actual income tax expense for the six months ended June 30, 2026 and 2025 differs from the statutory tax expense for the periods (computed by applying the U.S. federal corporate tax rate of 21 % for both 2026 and 2025 periods to income before income tax expense) as follows (in thousands): Six Months Ended June 30, 2026 2025 Amount % Pre-tax Income Amount % Pre-tax Income Computed tax at the statutory federal income tax rate $ 5,124 21.00% $ 4,376 21.00% Increase (decrease) resulting from: State income taxes, net of federal tax benefit (1) 1,122 4.60% 905 4.34% Bank owned life insurance income (257) (1.05%) (242) (1.16%) Benefit from stock-based compensation (377) (1.55%) - - Section 162(m) limitation 322 1.32% - - Other adjustments, net 37 0.15% - - Total tax expense $ 5,971 24.47% $ 5,039 24.18% (1) Taxes in Florida made up the majority (greater than 50 %) of the tax effect in this category.

In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and tax planning strategies in making this assessment. The major tax jurisdictions where the Company files income tax returns are the U.S. federal jurisdiction and the State of Florida. With few exceptions, the Company is no longer subject to U.S. federal and state income tax return examinations by tax authorities for years before 2022. For the six months ended June 30, 2026 and 2025 the Company did no t have any unrecognized tax benefits as a result of tax positions taken during a prior period or during the current period. Additionally, no interest or penalties were recorded as a result of tax uncertainties. 6. OFF-BALANCE SHEET ARRANGEMENTS The Company is a party to financial instruments with off-balance-sheet risk in the normal course of business in order to meet the financial needs of its customers and to reduce its own exposure to fluctuations in interest rates. These financial instruments include unfunded commitments under lines of credit, commitments to extend credit, and standby and commercial letters of credit. Those instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the Company’s Consolidated Balance Sheets. The Company uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. The Company's exposure to credit loss in the event of nonperformance by the other party to the financial instruments for unused lines of credit and standby letters of credit is represented by the contractual amount of these commitments. Table of Contents USCB FINANCIAL HOLDINGS, INC. Notes to the Consolidated Financial Statements - Unaudited 23 USCB Financial Holdings, Inc. Q2 2026 Form 10-Q A summary of the amounts of the Company's financial instruments with off-balance sheet risk are shown below at June 30, 2026 and December 31, 2025 (in thousands): June 30, 2026 December 31, 2025 Commitments to grant loans and unfunded lines of credit $ 205,573 $ 161,606 Standby and commercial letters of credit 3,646 2,700 Total $ 209,219 $ 164,306 Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses. Unfunded lines of credit and revolving credit lines are commitments for possible future extensions of credit to existing customers. These lines of credit are uncollateralized and usually do not contain a specified maturity date and ultimately may not be drawn upon to the total extent to which the Company committed. Standby and commercial letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. Those letters of credit are primarily issued to support public and private borrowing arrangements. Essentially all letters of credit have fixed maturity dates and since many of them expire without being drawn upon, they do not generally present a significant liquidity risk to the Company. Changes in the ACL for the three and six months ended June 30, 2026 and 2025 were as follows (in thousands): Three Months Ended June 30, Six Months Ended June 30, 2026 2025 2026 2025 Beginning balance $ 957 $ 581 $ 752 $ 571 Provision for credit losses - off-balance sheet arrangements 380 134 585 144 Total $ 1,337 $ 715 $ 1,337 $ 715 7. DERIVATIVES The Company utilizes interest rate swap agreements as part of its asset-liability management strategy to help manage its interest rate risk exposure. The notional amount of the interest rate swaps does not represent actual amounts exchanged by the parties. The amounts exchanged are determined by reference to the notional amount and the other terms of the individual interest rate swap agreements. Interest Rate Swaps Designated as a Cash Flow Hedge As of June 30, 2026, the Company had two costless collar hedges with a notional amount of $ 100 million that were designated as cash flow hedges of two three-month brokered CDs. The derivatives are based on the USD SOFR overnight index and have a weighted average cap rate of 4.50 % and weighted average floor rate of 1.763 %, effectively creating a defined range of interest rate outcomes without requiring an upfront premium. The costless collar hedges have an average maturity of 1.04 years. As of December 31, 2025, the Company had two costless collar hedges with a notional amount of $ 100 million that were designated as cash flow hedge of two three-month brokered CDs. The derivatives are based on the USD SOFR overnight index and have a weighted average cap rate of 4.50 % and weighted average floor rate of 1.763 %, effectively creating a defined range of interest rate outcomes without requiring an upfront premium. The costless collar hedges had an average maturity of 1.54 years. During the three months ended June 30, 2026, one interest rate swap agreement matured. As of June 30, 2026, the Company had no outstanding interest rate swap agreements. As of December 31, 2025, the Company had one interest rate swap agreement with a notional aggregate amount of $ 25 million that was designated as cash flow hedge of a certificate of deposit. Under the agreement, the Company paid a Table of Contents USCB FINANCIAL HOLDINGS, INC. Notes to the Consolidated Financial Statements - Unaudited 24 USCB Financial Holdings, Inc. Q2 2026 Form 10-Q fixed rate of 3.47 % and received a variable rate based on the weighted ‑ average three ‑ months compounded USD SOFR. The swap had a maturity of 0.42 years. During the quarter ended December 31, 2025, the Company unwound a separate interest rate swap designated as a cash flow hedge of certificate of deposit with notional amount of $ 25 million. The decision to unwind this swap was driven by changes in interest rate forecasts and asset-liability management strategies. The early termination income to unwind the fair value swaps totaled $ 5 thousand. The original maturity of the cash flow interest rate swap that was unwound during the quarter was April 2026. The changes in fair value of these interest rate swaps are recorded in other assets or accrued interest and other liabilities with a corresponding recognition in other comprehensive income (loss) and subsequently reclassified to earnings when gains or losses are realized. Interest Rate Swaps The Company enters into interest rate swaps with its loan customers. The Company had 122 and 94 interest rate swaps with loan customers with an aggregate notional amount of $ 401.9 million and $ 310.8 million at June 30, 2026 and December 31, 2025, respectively. At June 30, 2026, these interest rate swaps mature between 2027 and 2051. The Company entered into corresponding and offsetting derivatives with third parties. The fair value of the liability created by these derivatives requires the Company to provide the counterparty with funds to be held as collateral which the Company reports as other assets under the Consolidated Balance Sheets. While these derivatives represent economic hedges, they do not qualify as hedges for accounting purposes. The following table reflects the Company’s interest rate swaps at the dates indicated (in thousands): Fair Value Notional Amount Collateral Amount Balance Sheet Location Asset Liability June 30, 2026: Derivatives designated as cash flow hedges: Interest rate swaps $ 100,000 $ - Other assets/Accrued interest and other liabilities $ 92 $ - Derivatives not designated as hedging instruments: Interest rate swaps related to customer loans $ 401,882 $ 7,037 Other assets/Accrued interest and other liabilities $ 6,615 $ 6,615 December 31, 2025: Derivatives designated as cash flow hedges: Interest rate swaps $ 125,000 $ - Other assets/Accrued interest and other liabilities $ 14 $ 33 Derivatives not designated as hedging instruments: Interest rate swaps related to customer loans $ 310,761 $ 5,769 Other assets/Accrued interest and other liabilities $ 9,753 $ 9,753 8. FAIR VALUE MEASUREMENTS Determination of Fair Value The Company uses fair value measurements to record fair-value adjustments to certain assets and liabilities and to determine fair value disclosures. In accordance with the fair value measurements accounting guidance, the fair value of a financial instrument is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is best determined based upon quoted market prices. However, in many instances, there are no quoted market prices for the Company's various financial instruments. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. Accordingly, the fair value estimates may not be realized in an immediate settlement of the instrument. Table of Contents USCB FINANCIAL HOLDINGS, INC. Notes to the Consolidated Financial Statements - Unaudited 25 USCB Financial Holdings, Inc. Q2 2026 Form 10-Q The fair value guidance provides a consistent definition of fair value, which focuses on exit price in an orderly transaction (that is, not a forced liquidation or distressed sale) between market participants at the measurement date under current market conditions. If there has been a significant decrease in the volume and level of activity for the asset or liability, a change in valuation technique or the use of multiple valuation techniques may be appropriate. In such instances, determining the price at which willing market participants would transact at the measurement date under current market conditions depends on the facts and circumstances and requires the use of significant judgment. The fair value is a reasonable point within the range that is most representative of fair value under current market conditions. Fair Value Hierarchy In accordance with this guidance, the Company groups its financial assets and financial liabilities generally measured at fair value in three levels, based on the markets in which the assets and liabilities are traded, and the reliability of the assumptions used to determine fair value. Level 1 - Valuation is based on quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. Level 1 assets and liabilities generally include debt and equity securities that are traded in an active exchange market. Valuations are obtained from readily available pricing sources for market transactions involving identical assets or liabilities. Level 2 - Valuation is based on inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. The valuation may be based on quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the asset or liability. Level 3 - Valuation is based on unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Level 3 assets and liabilities include financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which determination of fair value requires significant management judgment or estimation. A financial instrument's categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. Items Measured at Fair Value on a Recurring Basis AFS investment securities: When instruments are traded in secondary markets and quoted market prices do not exist for such securities, management generally relies on prices obtained from independent vendors or third-party broker-dealers. Management reviews pricing methodologies provided by the vendors and third-party broker-dealers in order to determine if observable market information is being utilized. Securities measured with pricing provided by independent vendors or third- party broker-dealers are classified within Level 2 of the hierarchy and often involve using quoted market prices for similar securities, pricing models or discounted cash flow analyses utilizing inputs observable in the market where available. Derivatives: The fair values of derivatives are measured with pricing provided by third-party participants and are classified within Level 2 of the hierarchy.

The fair value of the collateral-dependent loan was determined using the appraised value of the underlying real estate collateral, adjusted for the estimated impact of senior lien positions, SBA participation interests, and estimated costs to sell. The application of these adjustments resulted in a fair value below the amortized cost, which was recognized through a charge-off and reflected in the carrying value of the loan. The resulting fair value attributable to the Company's exposure was approximately of $ 0 . The loan had an outstanding amortized cost basis of approximately $ 64 thousand and a specific reserve of $ 64 thousand at June 30, 2026. As of December 31, 2025, collateral-dependent loans classified within Level 3 of the fair value hierarchy had an aggregate fair value of $ 2.6 million and no specific reserve, as the appraised value of the underlying collateral exceeded the outstanding loan balance.

Dividends Declaration of dividends by the Board of Directors is required before dividend payments are made. The Company is limited in the amount of cash dividends that it may pay. Payment of dividends is generally limited to the Company’s net income for the current year combined with the Company’s retained income for the preceding two years, as defined by state banking regulations. However, for any dividend declaration, the Company must consider additional factors such as the amount of current period net income, liquidity, asset quality, capital adequacy and economic conditions at the Bank since the Bank is the primary source of funds to fund dividends paid by the Company. It is likely that these factors would further limit the amount of dividends which the Company could legally declare. In addition, bank regulators have the authority to prohibit banks and bank holding companies from paying dividends if they deem such payment to be an unsafe or unsound practice. As of June 30, 2026, the Company was not subject to any formal supervisory restrictions on its ability to pay dividends but will notify the Federal Reserve Bank of Atlanta in advance of any proposed dividend to the Company's stockholders in light of the Bank's negative retained earnings. In addition, under applicable FDIC regulations and policy, because the Bank has negative retained earnings, it must obtain the prior approval of the FDIC before effecting a cash dividend or other capital distribution from the Bank to the Company. The following table details the dividends declared and paid by the Company for the periods presented: Six Months Ended June 30, 2026 Declaration Date Record Date Payment Date Dividend Per Share Dividend Amount January 20, 2026 February 17, 2026 March 5, 2026 $ 0.125 $ 2.3 million April 20, 2026 May 15, 2026 June 5, 2026 $ 0.125 $ 2.3 million Six Months Ended June 30, 2025 Declaration Date Record Date Payment Date Dividend Per Share Dividend Amount January 21, 2025 February 14, 2025 March 5, 2025 $ 0.10 $ 2.0 million April 21, 2025 May 15, 2025 June 5, 2025 $ 0.10 $ 2.0 million The Bank exceeded all regulatory capital requirements and remained above “well-capitalized” guidelines as of June 30, 2026 and December 31, 2025. At June 30, 2026, the total risk-based capital ratio for the Bank was 13.68 %. See Note 12, Subsequent Events, for information regarding dividends declared in July 2026. 10. EARNINGS PER SHARE Earnings per share (“EPS”) for common stock is calculated using the two-class method required for participating securities. Basic EPS is calculated by dividing net income available to common shareholders by the weighted-average number of common shares outstanding for the period, without consideration for common stock equivalents. Diluted EPS is computed by dividing net income available to common shareholders by the weighted-average number of common shares outstanding for the period and the weighted-average number of dilutive common stock equivalents outstanding for the period Table of Contents USCB FINANCIAL HOLDINGS, INC.
