FIRST QUARTER 2026 COMPARED TO FOURTH QUARTER 2025

For the first quarter of 2026, net income available to common stockholders was $69.5 million, or $1.56 per diluted share, compared to $96.3 million, or $2.12 per diluted share, for the fourth quarter of 2025.

The $16.0 million provision for credit losses recorded in the first quarter of 2026 resulted primarily from an increase in criticized loans and $17.4 million in net charge-offs.

Net interest income was $254.7 million for the first quarter of 2026, compared to $267.4 million for the fourth quarter of 2025, primarily due to decreases in average earning assets and earning asset yields, partially offset by a decrease in funding costs. Net interest margin for the first quarter of 2026 was 3.43%, an increase of 5 basis points from the fourth quarter of 2025. Loans held for investment (“LHI”), excluding mortgage finance, yields decreased 6 basis points from the fourth quarter of 2025 and LHI, mortgage finance, yields decreased 14 basis points from the fourth quarter of 2025.

Non-interest income for the first quarter of 2026 increased $9.2 million compared to the fourth quarter of 2025 primarily due to increases in investment banking and advisory fees, trading income and other non-interest income.

Non-interest expense for the first quarter of 2026 increased $29.4 million compared to the fourth quarter of 2025, primarily due to an increase in salaries and benefits, primarily as a result of the effect of seasonal payroll expenses that peak in the first quarter.

FIRST QUARTER 2026 COMPARED TO FIRST QUARTER 2025

Net income available to common stockholders was $69.5 million, or $1.56 per diluted share, for the first quarter of 2026, compared to $42.7 million, or $0.92 per diluted share, for the first quarter of 2025.

The first quarter of 2026 included a $16.0 million provision for credit losses, reflecting a linked quarter increase in criticized loans and $17.4 million in net charge-offs, compared to a $17.0 million provision for credit losses for the first quarter of 2025.

Net interest income increased to $254.7 million for the first quarter of 2026, compared to $236.0 million for the first quarter of 2025, primarily due to an increase in average earning assets and a decrease in funding costs. Net interest margin increased 24 basis points to 3.43% for the first quarter of 2026, as compared to the first quarter of 2025. LHI, excluding mortgage finance, yields decreased 21 basis points compared to the first quarter of 2025 and LHI, mortgage finance yields increased 6 basis points from the first quarter of 2025. Total cost of deposits decreased 38 basis points compared to the first quarter of 2025.

Non-interest income for the first quarter of 2026 increased $24.8 million compared to the first quarter of 2025 primarily due to increases in service charges on deposit accounts, investment banking and advisory fees, trading income and other non-interest income.

Non-interest expense for the first quarter of 2026 increased $10.5 million compared to the first quarter of 2025, primarily due to increases in salaries and benefits, occupancy expense and communications and technology expense, partially offset by a decrease in legal and professional expense.

CREDIT QUALITY

Net charge-offs of $17.4 million were recorded during the first quarter of 2026, compared to net charge-offs of $10.7 million and $9.8 million during the fourth quarter of 2025 and the first quarter of 2025, respectively. Criticized loans totaled $650.6 million at March 31, 2026, compared to $634.9 million at December 31, 2025 and $762.9 million at March 31, 2025. Non-accrual LHI totaled $144.9 million at March 31, 2026, compared to $116.9 million at December 31, 2025 and $93.6 million at March 31, 2025. The ratio of non-accrual LHI to total LHI for the first quarter of 2026 was 0.58%, compared to 0.49% for the fourth quarter of 2025 and 0.42% for the first quarter of 2025. The ratio of total allowance for credit losses to total LHI was 1.32% at March 31, 2026, compared to 1.38% and 1.48% at December 31, 2025 and March 31, 2025, respectively.

All regulatory ratios continue to be in excess of “well capitalized” requirements as of March 31, 2026. CET1, tier 1 capital, total capital and leverage ratios were 12.0%, 13.4%, 15.9% and 12.1%, respectively, at March 31, 2026, compared to 12.1%, 13.6%, 16.1% and 11.7%, respectively, at December 31, 2025 and 11.6%, 13.1%, 15.6% and 11.8%, respectively, at March 31, 2025.

GAAP TO NON-GAAP RECONCILIATIONS

The following items are non-GAAP financial measures: adjusted non-interest income, adjusted total revenue, adjusted non-interest expense, adjusted income tax expense, adjusted net income, adjusted net income available to common stockholders, adjusted pre-provision net revenue (“PPNR”), adjusted diluted earnings per common share, adjusted return on average assets, adjusted return on average common equity, adjusted efficiency ratio, adjusted non-interest income to average earning assets and adjusted non-interest expense to average earning assets. These are not measures recognized under GAAP and therefore are considered non-GAAP financial measures. The table below provides a reconciliation of these non-GAAP financial measures to the most comparable GAAP measures.

These non-GAAP financial measures are adjusted for certain items, listed below, that management believes are non-operating in nature and not representative of its actual operating performance. Management believes that these non-GAAP financial measures provide meaningful additional information about Texas Capital Bancshares, Inc. to assist management and investors in evaluating operating results, financial strength, business performance and capital position. Non-GAAP financial measures have inherent limitations, are not required to be uniformly applied and are not audited. As such, these non-GAAP financial measures should not be considered in isolation or as a substitute for analyses of operating results or capital position as reported under GAAP.

15 Non-GAAP Reconciliation // Return on Average Tangible Common Equity (ROATCE) ROATCE is a non-GAAP financial measure. ROATCE represents the measure of net income available to common shareholders as a percentage of average tangible common equity. ROATCE is used by management in assessing financial performance and use of equity. A reconcilement of ROATCE to the most directly comparable U.S. GAAP measure, ROACE, for all periods is presented below.
