Company Completed Acquisition of NBC Oklahoma, Adding Seven Locations

WICHITA, Kansas, October 14, 2025 (BUSINESSWIRE) – Equity Bancshares, Inc. (NYSE: EQBK), (“Equity”, “the Company,” “we,” “us,” “our”), the Wichita-based holding company of Equity Bank, reported a net loss of $29.7 million or $1.55 per diluted share for the quarter ended September 30, 2025. Adjusting for pre-tax expenses associated with our merger with NBC Corp of Oklahoma ("NBC"), losses realized on the repositioning of our bond portfolio and double-count provisioning for NBC loans pre-tax income was $28.4 million. Tax effecting at 21%, adjusted net income was $22.5 million, or $1.17 per diluted share.

“Our Company continued to execute in the third quarter of 2025 as we closed and integrated our merger with NBC, announced a definitive agreement with Frontier Holdings LLC ("Frontier"), reissued subordinated debt, repositioned the remainder of our investment portfolio and continued to service our customers and our communities," said Brad S. Elliott, Chairman and CEO of Equity. “Our accomplishments in the quarter and throughout 2025 position our Company for continued success as we execute on our mission to empower our employees, customers and communities.

“I couldn’t be more proud of our employees and partners. Transformational quarters like these are not possible without excellent operators committing to accomplishing significant tasks,” Mr. Elliott continued. “Our teams are motivated to realize the benefits of our continued expansion efforts and to continue driving our organization forward.”

Notable Items:

Financial Results for the Quarter Ended September 30, 2025

Net loss allocable to common stockholders was $29.7 million, or $(1.55) per diluted share, as compared to net income allocable to common stockholders of $15.3 million, or $0.86 per diluted share in the prior quarter. The drivers of the periodic change are discussed in detail in the following sections. Excluding merger expenses, provisioning for acquired loan assets, and the cost realized in repositioning the bond portfolio pre-tax earnings were $28.4 million. Tax effected at 21% results in core net income of $22.5 million, or $1.17 per diluted share.

Net Interest Income

Net interest income was $62.5 million for the period, as compared to $49.8 million in the previous quarter. The increase was primarily driven by the addition of assets from the NBC merger which closed on July 2, 2025. The repositioning of investments was completed in the second half of the quarter, with benefits expected to be fully realized in future periods.

Average interest-bearing liabilities as a percentage of average interest earning assets declined to 74.2%, while total average interest earning assets increased $783.2 million during the quarter. Yield on interest earning assets increased by 27 basis points, while cost of interest bearing liabilities increased 3 basis points, both primarily attributable to the acquisition of NBC.

Provision for Credit Losses

During the quarter, there was a provision of $6.2 million compared to $19 thousand in the previous quarter. The primary driver of the periodic change was the addition of non-purchased credit deteriorated loans from the NBC merger. As of the end of the quarter, these loans had balances of $631.2 million and contributed $6.2 million to the allowance for credit losses all of which required funding through provision in the quarter. Exclusive of these assets there would not have been any provisioning during the quarter as charge-offs were predominantly on loans with specific reserves at the end of the previous quarter and loan balances were materially consistent.

During the quarter, the bank realized net charge-offs of $1.1 million as compared to $573 thousand, realizing an annualized ratio of charge-offs to average loans of 10 basis points. Year to date, the bank has realized net charge-offs $1.8 million or 6 basis points of average loans on an annualized basis.

At the close of the quarter, the ratio of allowance for credit losses to gross loans held for investment was 1.25%. The Company continues to estimate the allowance for credit loss with assumptions that anticipate slower prepayment rates and continued market disruption caused by trade policy, elevated inflation, supply chain issues and the impact of monetary policy on consumers and businesses.

Non-Interest Income

Total non-interest income for the quarter included a loss of $53.4 million on the sale of securities related to our repositioning during the quarter. Excluding this amount, adjusted non-interest income was $8.9 million for the quarter, as compared to $8.6 million linked quarter an increase of $284 thousand, or 3.3%. The periodic change was driven by the addition of NBC during the quarter and realized in service revenues including treasury, debit card, credit card, mortgage and trust and wealth management.

Non-Interest Expense

Total non-interest expense for the quarter was $49.1 million as compared to $40.0 million for the previous quarter. Adjusting for merger expenses in both periods, non-interest expense increased $3.3 million, or 8.3%. The increase during the period is primarily attributable to the addition of NBC at the beginning of the quarter. System conversions for NBC took place at the end of August. Exclusive of merger expenses, annualized non-interest expense as a percentage of average assets declined 20 basis points to 2.8%.

Also included in non-interest expense for the quarter were losses related to the disposition of other real estate owned totaling $777 thousand.

Income Tax Expense

At September 30, 2025, the effective tax rate for the quarter was 20.5% as compared to a rate of 16.9% for the quarter ended June 30, 2025. The year-to-date tax rate is not meaningful through September 30, 2025 compared to 18.6% at June 30, 2025.

The increase in the quarter over quarter tax rate (indicating a greater tax benefit with a pre-tax loss) was the result of additional tax benefits associated with the loss on the sale of bonds, generating pre-tax losses in the current quarter in conjunction with the reversal of tax expense booked in previous quarters offset by return to provision adjustments related to the 2024 federal income tax return. The anticipated tax rate for the full year with the loss on the sale of the bonds is anticipated to be between 17% and 19%.

Loans, Total Assets and Funding

Loans held for investment were $4.3 billion at period end, increasing $667.9 million during the quarter. At merger close, NBC contributed loans held for investment of $664.6 million. Excluding these balances, loan held for investment grew $3.3 million in the quarter and $103.3 million year to date. Total assets closed the quarter at $6.4 billion, a $982.4 million increase from prior quarter end.

Total deposit balances closed the quarter at $5.1 billion as compared to $4.2 billion as of the previous quarter end, an increase of $859.9 million, or 20.3%. NBC contributed balances of $808.0 million as of the close date and brokered deposits increased $14.6 million. Excluding these items, organic deposit growth during the quarter was $37.3 million. Brokered deposits closed the quarter at 3.0% of total deposits down from 3.3% linked quarter.

Asset Quality

Nonperforming assets were $52.6 million, or 0.8% of total assets, compared to $45.7 million as of the end of the previous quarter, or 0.9% of total assets. Non-accrual loans were $48.6 million, as compared to $42.6 million at the end of the previous quarter. Total classified assets, including loans rated special mention or worse, other real estate owned, excluding previous branch locations, and other repossessed assets were $82.9 million, or 12.4% of regulatory capital, up from $71.0 million, or 11.4% of regulatory capital as of the end of the previous quarter. The periodic increase in nonaccrual and classified assets is attributable to our acquisition of NBC, contributing $7.0 million in nonaccrual balances and $16.7 million in classified assets.

Capital

Quarter over quarter, book capital increased $76.3 million to $711.9 million. The increase is reflective of the capital issued to facilitate the NBC transaction in addition to current period earnings exclusive of losses realized on the repositioning of our investment portfolio. Tangible book value and Tangible book value per share closed the quarter at $605.6 million and $31.69, down from $32.17 linked quarter. The decline reflects the impact of the NBC transaction.

The Company’s ratio of common equity tier 1 capital to risk-weighted assets was 12.9%, the total capital to risk-weighted assets was 16.1% and the total leverage ratio was 10.4% at September 30, 2025. At June 30, 2025, the Company’s common equity tier 1 capital to risk-weighted assets ratio was 15.0%, the total capital to risk-weighted assets ratio was 16.8% and the total leverage ratio was 12.1%.

Equity Bank's ratio of common equity tier 1 capital to risk-weighted assets was 13.2%, total capital to risk-weighted assets was 14.3% and the total leverage ratio was 10.3% at September 30, 2025. At June 30, 2025, Equity Bank’s ratio of common equity tier 1 capital to risk-weighted assets was 14.4%, the ratio of total capital to risk-weighted assets was 15.6% and the total leverage ratio was 11.1%.

Non-GAAP Financial Measures

In addition to evaluating the Company’s results of operations in accordance with accounting principles generally accepted in the United States of America (“GAAP”), management periodically supplements this evaluation with an analysis of certain non-GAAP financial measures that are intended to provide the reader with additional perspectives on operating results, financial condition and performance trends, while facilitating comparisons with the performance of other financial institutions. Non-GAAP financial measures are not a substitute for GAAP measures, rather, they should be read and used in conjunction with the Company’s GAAP financial information.

The efficiency ratio is a common comparable metric used by banks to understand the expense structure relative to total revenue. In other words, for every dollar of total revenue recognized, how much of that dollar is expended. To improve the comparability of the ratio to our peers, non-core items are excluded. To improve transparency and acknowledging that banks are not consistent in their definition of the efficiency ratio, we include our calculation of this non-GAAP measure.

Core income calculations are a non-GAAP measure that management believes is an effective alternative measure of how efficiently the company utilizes its asset base. Core income is calculated by adjusting GAAP income by non-core gains and losses and excluding non-core expenses, net of tax, as outlined in the table below. We calculate (a) core net income (loss) allocable to common stockholders plus merger expenses, tax effected non-core items, goodwill impairment and BOLI tax adjustment, less gain (loss) from securities transactions; (b) adjusted operating net income as net income (loss) allocable to common stockholders plus adjusted non-core items, tax effected non-core items and BOLI tax adjustments

Core return on average assets before income tax provision and provision for loan losses is a measure that the Company uses to understand fundamental operating performance before these expenses. Used as a ratio relative to average assets, we believe it demonstrates “core” performance and can be viewed as an alternative measure of how efficiently the Company services its asset base. Used as a ratio relative to average equity, it can function as an alternative measure of the Company’s earnings performance in relationship to its equity.

Core return on average equity is a non-GAAP measure generally used by financial analysts and investment bankers to evaluate financial institutions. We calculate by taking core net income allocable to common stockholders divided by a simple average of net income and core net income plus average stockholders' equity. For return on average equity, the most directly comparable financial measure calculated in accordance with GAAP is return on average equity.

Core earnings per share is a non-GAAP financial measures we calculate by taking GAAP net income less non-core impacts to net income to arrive at core net income and core diluted earnings per share. This financial measure is used by financial statement users to evaluate the core financial performance of the Company

Tangible common equity and related measures are non-GAAP financial measures that exclude the impact of intangible assets, net of deferred taxes, and their related amortization. These financial measures are useful for evaluating the performance of a business consistently, whether acquired or developed internally. Return on average tangible common equity is used by management and readers of our financial statements to understand how efficiently the Company is deploying its common equity.

Companies that are able to demonstrate more efficient use of common equity are more likely to be viewed favorably by current and prospective investors.

The Company believes that disclosing these non-GAAP financial measures is both useful internally and is expected by our investors and analysts in order to understand the overall performance of the Company. Other companies may calculate and define their non-GAAP financial measures and supplemental data differently. A reconciliation of GAAP financial measures to non-GAAP measures and other performance ratios, as adjusted, are included in Table 6 in the following press release tables.
