Exhibit 99.1

This presentation contains “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended.  These forward-looking statements reflect the current views of the management of Equity Bancshares, Inc. (“Equity,” “we,” “us,” “our,” “the company”) with respect to, among other things, future events and Equity’s financial performance. These statements are often, but not always, made through the use of words or phrases such as “may,” “should,” “could,” “predict,” “potential,” “believe,” “will likely result,” “expect,” “continue,” “will,” “anticipate,” “seek,” “estimate,” “intend,” “plan,” “project,” “forecast,” “goal,” “target,” “would” and “outlook,” or the negative variations of those words or other comparable words of a future or forward-looking nature.  These forward-looking statements are not historical facts, and are based on current expectations, estimates and projections about Equity’s industry, management’s beliefs and certain assumptions made by management, many of which, by their nature, are inherently uncertain and beyond Equity’s control. Accordingly, Equity cautions you that any such forward-looking statements are not guarantees of future performance and are subject to risks, assumptions and uncertainties that are difficult to predict. Although Equity believes that the expectations reflected in these forward-looking statements are reasonable as of the date made, actual results may prove to be materially different from the results expressed or implied by the forward-looking statements.  Factors that could cause actual results to differ materially from Equity’s expectations include competition from other financial institutions and bank holding companies; the effects of and changes in trade, monetary and fiscal policies and laws, including interest rate policies of the Federal Reserve Board; changes in the demand for loans; fluctuations in value of collateral and loan reserves; inflation, interest rate, market and monetary fluctuations; changes in consumer spending, borrowing and savings habits; the possibility that the expected benefits related to the proposed transaction with NBC Corp. of Oklahoma (“NBC”) may not materialize as expected; the proposed transaction not being timely completed, if completed at all; prior to the completion of the proposed transaction, the business of NBC experiencing disruptions due to transaction-related uncertainty or other factors making it more difficult to maintain relationships with employees, customers, other business partners or governmental entities, difficulty retaining key employees; the ability to obtain regulatory approval of the NBC transactions; and the ability to successfully implement integration strategies or to achieve expected synergies and operating efficiencies within the expected time-frames or at all; and similar variables. The foregoing list of factors is not exhaustive. For discussion of these and other risks that may cause actual results to differ from expectations, please refer to “Cautionary Note Regarding Forward-Looking Statements” and “Risk Factors” in Equity’s Annual Report on Form 10-K filed with the Securities and Exchange Commission on March 7, 2025, and any updates to those risk factors set forth in Equity’s subsequent Quarterly Reports on Form 10-Q or Current Reports on Form 8-K. If one or more events related to these or other risks or uncertainties materialize, or if Equity’s underlying assumptions prove to be incorrect, actual results may differ materially from what Equity anticipates. Accordingly, you should not place undue reliance on any such forward-looking statements. Any forward-looking statement speaks only as of the date on which it is made, and Equity does not undertake any obligation to publicly update or review any forward-looking statement, whether as a result of new information, future developments or otherwise, except as required by law. New risks and uncertainties arise from time to time and it is not possible for us to predict those events or how they may affect us. In addition, Equity cannot assess the impact of each factor on Equity’s business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements. All forward-looking statements, expressed or implied, included in this press release are expressly qualified in their entirety by this cautionary statement. This cautionary statement should also be considered in connection with any subsequent written or oral forward-looking statements that Equity or persons acting on Equity’s behalf may issue. NON-GAAP FINANCIAL MEASURES  This presentation contains certain non-GAAP financial measures intended to supplement, not substitute for, comparable GAAP measures.  Reconciliations of non-GAAP financial measures to GAAP financial measures are provided at the end of this presentation.  Numbers in the presentation may not sum due to rounding.

Primary Drivers Net Interest Income Noninterest Income Rate Protection Noninterest Expense Provision for Credit Losses Net interest income was $50.3 million for the period, as compared to $49.5 million for previous quarter. Adjusting the stated number for non-recurring nonaccrual reversals and excess prepayment fee realization of $2.3 million in the current quarter and $1.5 million in the prior quarter, net interest income was $48.0 for each. A larger balance sheet and margin offset the day count variance in the period. Total non-interest income was $10.3 million for the quarter, as compared to $8.8 million linked quarter. Current quarter includes a $1.7 million comparative improvement in benefit from Bank Owned Life Insurance as we realized a death benefit during the period. Excluding this periodic change Noninterest income was down $200 thousand due to seasonally consistent soft results in service charges, mortgage and insurance revenues. Proactive effort to book variable rate assets subject to floor levels. Total non-interest expense for the quarter was $39.0 million as compared to $37.8 million for the previous quarter. The comparative increase during the period was driven by beginning of the year payroll dynamics as well as comparatively higher incentive accruals to account for positive earnings during the period. Excluding these items, non-interest expense was effectively flat quarter-over-quarter. $2.6 million in the provision for credit losses was realized in the quarter. While charge-off results were muted, the increase is due to loan growth coupled with increased economic uncertainty attributable to recent trad policy announcements. Allowance to total loans closed the quarter at 1.26%, up 3 bps to prior quarter reflecting the increased economic risk. Quarter over Quarter Walk Q4 Q1 Net Income Non-GAAP Financial Measure.

Cost of total deposits decreased 9bps and cost of interest-bearing deposits decreased 13bps in the quarter. Loan yield increased 1bps quarter-over-quarter, driven by purchase accounting and non-accrual impacts, offsetting 11bps lower coupon yield quarter-over-quarter. Investment yield increased 4bps quarter-over-quarter due to a comparatively shorter period.
