Notes to the Financial Statements December 31, 2025

### 1.

### Nature of Operations

TRB Capital Markets, LLC (the Company) was formed August 19, 2022 and commenced its operations with the acquisition of Estrada Hinojosa & Company, on August 2, 2024. The Company is a municipal securities dealer registered with the Securities and Exchange Commission (SEC) and a member of the Financial Industry Regulatory Authority (FINRA). The Company is a Texas limited liability company. The Company is a wholly owned subsidiary of Texas Regional Bank (TRB), which is a wholly owned subsidiary of Texas State Bankshares, Inc. (TSBI).

### Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America ("U.S. GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

### Concentrations of Credit Risk

The Company maintains its cash at its clearing correspondent broker dealer and in TRB deposit accounts which, at times, may exceed federally insured limits. The Company has not experienced any losses in such accounts and believes it is not exposed to any significant credit risk on cash and cash equivalents.

### Basis of Presentation

The Company is engaged in investment banking services which consists of several classes of services, including underwriting activities, financial advisory services, placement agent services, continuing disclosure submission services, and secondary market sales. The accompanying financial statements have been prepared in accordance with Generally Accepted Accounting Principles (GAAP).

### Cash and Interest-Bearing Deposits in Banks

For purposes of the statement of cash flows, cash and interest-bearing deposits in banks include deposits with banks and investments with maturities of three months or less that are not segregated and deposited for regulatory purposes.

At December 31, 2025, the Company's cash accounts exceeded federally insured limits by approximately \$15 million. The Company has not experienced any losses in such accounts.

### Cash Deposits with Clearing Organizations

Deposits with clearing broker-dealer represent cash required to be maintained at the clearing brokerdealer for clearing and trading activities. These balances are considered at risk as they are not federally insured. The Company conducts business with one clearing broker-dealer for its underwriting activities. The availability of these funds to the Company is governed by the agreements with the clearing firms and may vary depending upon the margin requirement on securities owned and other non-recurring debits, such as securities sold short, fails, and unanticipated price corrections.

Notes to the Financial Statements December 31, 2025

### Receivables from Brokers and Dealers

Receivables from Brokers and Dealers are reported on the statements of financial position at outstanding principal adjusted for any allowance for credit losses. The receivable is recognized upon completion of the performance obligation to the customer and collateral is not required. Receivables from Brokers and Dealers represent amounts that have been earned and billed to other Brokers related to underwriting and financial advisory services where the Company acts as co-lead or financial advisor to a transaction. The Company takes into consideration the composition of the receivables, current economic conditions, the estimated net realizable value of the underlying collateral, historical loss experience, and bankrupt accounts when determining management's estimate of probable credit losses and the adequacy of the allowance for credit losses. Any receivables deemed uncollectible are written off against allowance. The Company's expectation is that credit risk is not significant until receivables are more than 180 days past due. As of December 31, 2025, the Company had no accounts that management believed were uncollectible. Receivables related to contracts with brokers and dealers as of December 31, 2025 were \$1.3 million.

### Receivables from Customers

Receivables from Customers are reported on the statements of financial position at outstanding principal adjusted for any allowance for credit losses. The receivable is recognized upon completion of the performance obligation to the customer and collateral is not required. Receivables from customers represent amounts that have been earned and billed to clients in accordance with the terms of the Company's engagement letter or agreement with respective clients. The Company takes into consideration the composition of the receivables, current economic conditions, the estimated net realizable value of the underlying collateral, historical loss experience, delinquency, and bankrupt accounts when determining management's estimate of probable credit losses and the adequacy of the allowance for credit losses. Any receivables deemed uncollectible are written off against allowance. The Company's expectation is that credit risk is not significant until receivables are more than 180 days past due. Receivables related to contracts with customers as of December 31, 2025 were \$484 thousand and included in trade receivables on the statement of financial condition. As of December 31, 2025, the Company had no accounts that management believed were uncollectible.

#### Securities

Securities transactions are recorded on the trade date, as if they had settled. Securities owned are valued at fair value in accordance with Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 820, Fair Value Measurements and Disclosures, with the resulting difference between cost and fair value included in income for the period. The valuation of securities often requires judgments and estimates. The valuation is as of a specific date and such values may change significantly due to changes in interest rates, the credit quality of the issuer of the security or other market factors.

Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific identification method.

### Premises and Equipment

Premises and equipment are stated at cost, net of accumulated depreciation is recognized on the straight-line method based on the following estimated useful lives: buildings –40 years; equipment and furniture - 5 to 7 years; and software - 3 years. Leasehold improvements are amortized over the shorter of the lease term or respective estimated useful lives.

Notes to the Financial Statements December 31, 2025

### Goodwill and Intangible Assets

Goodwill is the excess of purchase price over fair value of identifiable net assets acquired in a business combination. Goodwill is not amortized but is tested for impairment annually or more frequently if a triggering event occurs. The Company elected the accounting alternative for evaluating goodwill impairment triggering events and performs a goodwill impairment triggering event evaluation only as of the end of each reporting period. A qualitative assessment is performed to determine whether the existence of events or circumstances leads to a determination that it is more likely than not the fair value of a reporting unit is less than the carrying amount, including goodwill. If, based on the evaluation, it is determined to be more likely than not that the fair value of a reporting unit is less than the carrying value, then goodwill is tested further for impairment. The quantitative impairment test consists of calculating the fair value of a reporting unit and comparing it to the carrying amount, including goodwill. The goodwill impairment loss, if any, is measured as the amount by which the carrying amount of a reporting unit, including goodwill, exceeds its fair value. Subsequent increases in goodwill value are not recognized in the consolidated financial statements. For the year ended December 31, 2025, the Company determined that no impairment of goodwill has occurred.

Intangible assets with finite lives are initially recorded at fair value and amortized on a straight-line basis over periods ranging from 6-12 years. Intangible assets are periodically evaluated as to the recoverability of carrying values.

#### Stock Incentive Plans

The Company accounts for share based compensation in accordance with ASC 718, Compensation – Stock Compensation, which requires the measurement of the cost of employee services received in exchange for restricted stock based on the grant-date fair value of the award, over the period the employee is required to provide services for the equity-classified award. Employees participate in an equity incentive plan, which provides for restricted stock that may only be settled in common shares of TSBI. The value of restricted stock is the value of TSBI stock at the date of the grant. The Company's accounting policy is to recognize forfeitures as they occur. TSBI allocates share-based compensation expense to the Company for employees receiving equity awards.

#### Revenue Recognition

The Company recognizes revenue in accordance with Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 606, Revenue from Contracts with Customers, which provides accounting guidance on the recognition of revenues from contracts and requires gross presentation of revenues and certain costs. Revenue from contracts with clients is recognized when the Company satisfies performance obligations by transferring the service to the client. A service is transferred to a client when the client obtains control and benefit of that service. The amount of revenue recognized reflects the consideration the Company expects to be entitled to in exchange for the service.

Revenues from the Company's investment banking operations include fees for financial advisory services and underwriting activities and gains and losses on secondary market sales.

The Company engages in the underwriting of municipal debt securities for governmental entities and public/private conduit issuers that use the proceeds from the sale of such securities for purposes specified in the issuer's official statement. Revenues arising from the primary offering of municipal debt securities for governmental entities and public/private conduit issuers for the bonds the Company is contracted to purchase are recognized on the trade date. The Company believes that the trade date is the

{9}------------------------------------------------

Notes to the Financial Statements December 31, 2025

appropriate point in time to recognize revenue arising from transactions of municipal debt underwritings since the terms of the transaction have been established, beneficial ownership has been transferred, all performance obligations have been satisfied, variable constraints are released and there is no significant action which the Company must undertake subsequent to this date.

The Company recognizes an underwriting expense at the time the related revenues are recorded. In the event that transactions are not completed, and the securities are not issued, the Company immediately expenses these costs.

The Company provides financial advisory services to governmental entities and public/private conduit issuers of municipal securities. Revenues are earned from the rendering of financial advice with respect to a public or private issuance of municipal securities or the structuring of a bank loan on behalf of the governmental entities and/or public/private conduit issuers. The Company recognizes financial advisory fees at a point in time when the related transaction or engagement is successfully completed, i.e. pricing date. Underwriting revenue is subject to variance constraint due to matters outside the control of the partnership such as market interest and competitive rates. These constraints are not resolved until the date of the bond issuance. The Company believes that pricing date is the appropriate point in time to recognize revenues arising from financial advisory services as that is when the customer receives the benefit of the services, all performance obligations have been satisfied, and there are no significant variable constraints.

The Company defers financial advisory expenses only to the extent they are explicitly reimbursable by the financial advisory client and records expenses when the related revenue has been recognized. Expenses reimbursed by our clients are recognized as financial advisory revenues; otherwise, financial advisory expenses are recognized as they are incurred.

Placement agent service receivables are earned in accordance with contract terms. Revenue related to these transactions is recognized at trade date. The Company believes that the performance obligation is satisfied on the trade date because that is when the underlying financial instrument or purchaser is identified, the pricing is agreed upon and the risks and rewards of ownership have been transferred to/from the customer. Any costs associated are recognized when incurred.

Interest and other income represent revenues that are not within the scope of ASC 606.

The economic conditions which affect the Company's operations are related to overall trends in the economy and can be significantly influenced by changes in interest rates and overall market conditions.

### Income Taxes

The Company is included in the consolidated federal income tax return filed by the Parent. The Company is a single member limited liability company disregarded for U.S. federal income tax purposes therefore, there is no future benefit or liability related to book and tax bases of assets or liabilities. Accordingly, the Company has not recorded current or deferred tax for the period ended December 31, 2025. The Company recorded no income tax expense due to the Parent company for the period ended December 31, 2025.

{10}------------------------------------------------

Notes to the Financial Statements

December 31, 2025

The Company recognizes and measures its unrecognized tax benefits in accordance with FASB ASC 740, Income Taxes. Under that guidance the Company assesses the likelihood, based on their technical merit, that tax positions will be sustained upon examination based on the facts, circumstances and information available at the end of each period. The measurement of unrecognized tax benefits is adjusted when new information is available, or when an event occurs that requires a change.

#### 2. Fair Value Measurements

The Company follows the provisions of ASC 820, Fair Value Measurements and Disclosures required about fair value measurements include, among other things, (1) the amounts and reasons for certain significant transfers among the three hierarchy levels of inputs; (2) the gross, rather than net, basis for certain Level 3 rollforward information; (3) use of a "class" basis rather than a major category basis for assets and liabilities; and (4) valuation techniques and inputs used to estimate Level 3 fair value measurements. The ASC defines fair value as the exchange price that would be received for an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date.

The ASC guidance establishes a fair value hierarchy for valuation inputs that prioritizes the inputs used in valuation methodologies into the following three levels:

- · Level 1 Quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access as of the measurement date.
- · Level 2 Observable inputs other than Level 1, including quoted prices for similar assets or liabilities, quoted prices in less active markets, or other observable inputs that can be corroborated by observable market data.
- Level 3 Unobservable inputs supported by little or no market activity for financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation.

The Company uses fair value to measure certain assets and liabilities on a recurring basis when fair value is the primary measure of accounting. Fair value is used on a nonrecurring basis to measure certain assets when applying lower of cost or market accounting or when adjusting carrying values, such as goodwill and intangible assets.

Fair value is also used when evaluating impairment on certain assets, including trading securities, goodwill and other intangibles, long-lived assets, and for disclosures of certain financial instruments.

There were no transfers among the three hierarchy levels of inputs.

{11}------------------------------------------------

Notes to the Financial Statements

December 31, 2025

The fair value of the Company's municipal bonds, which are classified within Level 2, is estimated using observable market inputs. These instruments are generally valued using prices obtained from independent pricing services or broker-dealer quotations. Observable inputs used in the valuation process include:

- · Recently executed transactions in the marketplace
- · Benchmark yield curves
- · Credit spreads and issuer-specific credit risk
- Reported trades and market corroborated data for similar securities
- Interest rate spreads and maturity profiles

The following table summarizes assets and liabilities measured at fair value by class on a recurring basis as reported on the statements of financial position as of December 31, 2025, segregated by level within the fair value measurement hierarchy (dollars in thousands):

#### 4. Premises and Equipment

Components of premises and equipment, included in the statements of financial position, are as follows (dollars in thousands):

|                                                    |   | 2025    |

| Premises and equipment, net                        | S | 345     |

Depreciation expense for the year ended December 31, 2025 totaled \$40 thousand.

The Company has several operating leases for locations and for equipment, which terminate between 2026 and 2029. As of December 31, 2025, the ROU assets totaled \$845 thousand.

The Company has lease agreements with non-lease components that relate to the lease components. The Company elected the practical expedient to account for non-lease components and the lease components to which they relate as a single lease component for all. In addition, the Company elected to keep shortterm leases with an initial term of 12 months or less off the statements of financial position.

The Company determines if an arrangement is a lease or contains a lease at inception. Leases result in the recognition of ROU assets and lease liabilities on the statements of financial position. ROU assets represent the right to use an underlying asset for the lease liabilities represent the obligation to make lease payments arising from the lease, measured on a discounted basis. The Company determines lease classification as operating or finance at the lease commencement date.

At lease inception, the lease liability is measured at the present value of the lease payments over the lease term. The ROU asset equals the lease liability adjusted for any initial direct costs, prepaid or deferred rent, and lease incentives. The Company has made a policy election to use an incremental borrowing rate, utilizing the FHLB Dallas yield curve, for the initial and subsequent measurement of all lease liabilities. The incremental borrowing rate is determined using a period comparable with the lease term.

Operating lease rental cost and finance lease amortization of right-of-use (ROU) assets are included within occupancy and equipment expenses, netted in the statements of income. Finance lease interest expense is included within other interest expense in the statements of income. The Company does not generally enter into leases which contain variable payments, other than due to the passage of time.

#### 6. Net Capital Requirements

The Company is subject to the SEC Uniform Net Capital Rule (SEC Rule 15c3-1), which requires the maintenance of minimum net capital and requires that the ratio of aggregate indebtedness to net capital, both as defined, shall not exceed 15 to 1; and the rule of the "applicable" exchange also provides that equity capital may not be withdrawn, or cash dividends paid if the resulting debt to net capital ratio would exceed 10 to 1. At December 31, 2025, the Company had net capital of \$12.85 million which was \$8.8 million in excess of its required net capital of \$4 million. The Company's net capital ratio was 4.69 to 1.

#### 7. Restricted Stock Units (RSUs)

The Company participates in TSBI's equity incentive plan, under which restricted stock units of TSBI's common stock may be granted to employees of the Company. In 2024, the Company issued 5,934 shares of restricted stock to select members of the Company's management team. In 2025, TSBI issued no shares of restricted stock to executive officers. The shares are subject to forfeiture provisions in the event that the officers cease employment with the Company during the term of the agreement. All shares vest ratably over five years. All restricted stock is granted at the fair value of common stock at the time of award. The RSUs are considered fixed awards as the number of shares and fair value are known at the date of grant and the fair value at the grant date is amortized over the vesting and/or service period. The forfeiture provisions on the shares granted in 2024 lapse on 100% of the shares at the end of five years. The restricted stock agreements include provisions that accelerate the vesting of the unvested restricted stock if a change of control occurs as defined by the agreements. The holders of the restricted stock are entitled to all rights of a shareholder with regard to the restricted stock including the right to receive dividends. Dividends on the unvested restricted stock are charged to retained earnings when declared.

The restricted stock awards were valued at \$44 per share at the date of grant in 2024. Therefore, the total compensation expense that will be recognized by the Company over the requisite service periods is \$261 thousand. The Company's accounting policy is to recognize forfeitures as they occur.

The Company recognized compensation expense related to the restricted stock awards of \$52 thousand in 2025.
