Organization Consolidation And Presentation Of Financial Statements [Abstract]
BASIS OF PRESENTATION	NOTE 1 – BASIS OF PRESENTATION The interim consolidated financial statements include the accounts of Equity Bancshares, Inc., its wholly owned subsidiaries, EBAC, LLC and Equity Bank and Equity Bank’s wholly owned subsidiaries, EBHQ, LLC and SA Holdings, Inc. These entities are collectively referred to as the “Company”. All significant intercompany accounts and transactions have been eliminated in consolidation. The accompanying unaudited condensed interim consolidated financial statements have been prepared in accordance with United States Generally Accepted Accounting Principles (“GAAP”) for interim financial information and in accordance with guidance provided by the Securities and Exchange Commission. Accordingly, they do not include all the information and footnotes required by GAAP for complete financial information. The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. In the opinion of management, the interim statements reflect all adjustments necessary for a fair presentation of the financial position, results of operations and cash flows of the Company on a consolidated basis and all such adjustments are of a normal recurring nature. These financial statements and the accompanying notes should be read in conjunction with the Company’s audited financial statements for the year ended December 31, 2019, included in the Company’s Annual Report on Form 10-K filed with the SEC on March 10, 2020. Operating results for the nine months ended September 30, 2020, are not necessarily indicative of the results that may be expected for the year ending December 31, 2020, or any other period. Reclassifications Some items in prior financial statements were reclassified to conform to the current presentation. Management determined the items reclassified are immaterial to the consolidated financial statements taken as a whole and did not result in a change in equity or net income for the periods reported. Risk and Uncertainties The outbreak of COVID-19 has adversely impacted a broad range of industries in which the Company’s customers operate and could impair their ability to fulfill their financial obligations to the Company. The World Health Organization has declared COVID-19 to be a global pandemic indicating that almost all public commerce and related business activities must be, to varying degrees, curtailed with the goal of decreasing the rate of new infections. The spread of the outbreak has caused significant disruptions in the U.S. economy and has disrupted banking and other financial activity in the areas in which the Company operates. While there has been no material impact to the Company’s employees to date, COVID-19 could also potentially create widespread business continuity issues for the Company. Congress, the President, and the Federal Reserve have taken several actions designed to cushion the economic fallout. Most notably, the CARES Act was signed into law at the end of March 2020 as a $2 trillion legislative package. The goal of the CARES Act is to prevent a severe economic downturn through various measures, including direct financial aid to American families and economic stimulus to significantly impacted industry sectors. The package also includes extensive emergency funding for hospitals and medical providers. In addition to the general impact of COVID-19, certain provisions of the CARES Act as well as other recent legislative and regulatory relief efforts are expected to have a material impact on the Company’s operations. The Company’s business is dependent upon the willingness and ability of its employees and customers to conduct banking and other financial transactions. If the global response to contain COVID-19 is unsuccessful, the Company could experience a material adverse effect on its business, financial condition, results of operations and cash flows. While it is not possible to know the full universe or extent that the impact of COVID-19, and resulting measures to curtail its spread, will have on the Company’s operations, the Company is disclosing potentially material items of which it is aware. Financial position and results of operations The Company’s interest income and fees could be reduced due to COVID-19. In keeping with guidance from regulators, the Company is actively working with COVID-19 affected borrowers to defer their payments, interest, and fees. While interest and fees will still accrue to income, through normal GAAP accounting, should eventual credit losses on these deferred payments emerge, interest income and fees accrued would need to be reversed. In such a scenario, interest income in future periods could be negatively impacted. At this time, the Company is unable to project the materiality of such an impact but recognizes the breadth of the economic impact may affect its borrowers’ ability to repay in future periods. Capital and liquidity As of September 30, 2020, all our capital ratios, and our subsidiary bank’s capital ratios, were in excess of regulatory requirements. While we are currently classified as well capitalized, an extended economic recession brought about by COVID-19 could adversely impact our reported and regulatory capital ratios by further credit losses. The Company relies on cash on hand as well as dividends from its subsidiary bank to service its debt. If the Company’s subsidiary bank’s capital deteriorates such that it is unable to pay dividends to the Company for an extended period of time, the Company may not be able to service its debt. The Company maintains access to multiple sources of liquidity. Wholesale funding markets have remained open to us, but rates for short term funding have historically been volatile. If funding costs are elevated for an extended period of time, it could have an adverse effect on the Company’s net interest margin. If an extended recession caused large numbers of the Company’s deposit customers to withdraw their funds, the Company might become more reliant on volatile or more expensive sources of funding. Asset valuation Currently, the Company does not expect COVID-19 to affect its ability to account timely for the assets on its balance sheet; however, this could change in future periods. While certain valuation assumptions and judgments will change to account for pandemic-related circumstances such as widening credit spreads, the Company does not anticipate significant changes in methodology used to determine the fair value of assets measured in accordance with GAAP. At September 30, 2020, the Company performed a quantitative analysis to assess goodwill for impairment of Equity Bancshares, Inc., the sole reporting unit. Consideration was given to the on-going economic market disruption, the movement of the Company’s stock price in relation to other bank indexes and the length of time that the market value of the reporting unit has been below its book value as triggering events and completed a quantitative analysis to assess whether or not goodwill was impaired. This analysis determined that goodwill was impaired and subsequently the Company booked a non-cash impairment charge of $104,831 to goodwill on September 30, 2020. The determination of the fair value of the reporting unit incorporates assumptions that marketplace participants would use in their estimates of fair value in a change in control transaction, as prescribed by ASC Topic 820. To arrive at a conclusion of fair value, we utilized both the income approach and the market approach and then applied weighting factors to each approach. Weighting factors represent our best business judgement of the weightings a market participant would utilize in arriving at fair value of the reporting unit. In performing the analysis, Company management made numerous assumptions with respect to industry performance, reporting unit business performance, economic and market conditions and various other matters, many of which require significant management judgement. Projections related to business unit performance over the next five years assumed an economic downturn over a 12-month time horizon subsequently returning to conservative positive growth rates in loan and deposits after that time period. The analysis performed and the assumptions that are incorporated into the analysis reflect the best currently available estimates and judgements as to the expected future financial performance of the reporting unit. At September 30, 2020, the Company had goodwill of $31,601 which could be at risk of further impairment with further declines in performance, stock price or market conditions for bank stocks. Processes, controls and business continuity plan As of September 30, 2020, all the Company’s bank locations were open to customers with social distancing measures in place, allowing full access for customer use. Customers are served by appointment, calling ahead, curbside and drive-through but offered full lobby access during normal hours. The Company does not anticipate incurring additional material cost related to its continued deployment of the preparedness plan and no material operational or internal control challenges or risks have been identified to date. The Company does not anticipate significant challenges to its ability to maintain its systems and controls in light of the measures the Company has taken to prevent the spread of COVID-19. The Company has not experienced any material resource constraints through the implementation of its business continuity plans. Lending operations and accommodations to borrowers In keeping with regulatory guidance to work with borrowers during this unprecedented situation and as outlined in the CARES Act, the Company has worked with customers affected by COVID-19 and offered short-term assistance in accordance with regulatory guidelines. Commercial borrowers needing assistance have been offered either a 90-day principal and interest deferral or a 180-day principal only deferral. Commercial borrowers that originally requested a 90-day deferral can request an additional 90-day deferral by providing their previous year financial information, current year interim financial information, projections for the balance of the calendar year and information related to their cash reserves to show a need for the additional 90-day deferral. Consumers needing assistance have been offered a 90-day principal and interest deferral with an option to request an additional 90-day deferral. At the end of the deferral period, the interest will be capitalized and the loan re-amortized generally causing a minimal increase to payments for most consumers. As of September 30, 2020, the Company had 68 remaining deferrals on outstanding loan balances of $41,228, with interest deferred of $306. In accordance with interagency guidance issued in March 2020, these short-term deferrals are not automatically considered troubled debt restructurings, are not reflected in past due loan balances and have not been reported as a classified loan solely due to a deferral. These deferred loans are subject to ongoing monitoring and will be downgraded or placed on nonaccrual if a noted weakness exists. The following table lists loans by category that have been deferred under the payment deferral program at September 30, 2020. September 30, 2020 Commercial real estate $ 4,965 Commercial and industrial 25,746 Residential real estate 9,752 Agricultural real estate 643 Consumer 122 Total loans $ 41,228 With the passage of the Paycheck Protection Program (“PPP”), administered by the Small Business Administration (“SBA”), the Company actively participated in assisting its customers with applications for resources through the program. PPP loans originated prior to June 5, 2020, have a two-year five-year Credit As a result of the current economic environment caused by the COVID-19 virus, the Company is engaging in frequent communication with borrowers to better understand their situation and the challenges faced, allowing the Company to respond proactively as needs and issues arise. Should economic conditions worsen, the Company could experience further increases in its required allowance for loan losses and record additional provision for loan losses. It is possible that the Company’s asset quality measures could worsen at future measurement periods if the effects of COVID-19 are prolonged. Many industries have and will continue to experience adverse impacts as a result of COVID-19. Our exposure from outstanding loans and commitments to industries which we consider a higher risk totaled approximately $285,943 in hospitality and $65,088 in aircraft manufacturing. Recent Accounting Pronouncements In June 2016, FASB issued ASU 2016-13, Financial Instruments – Credit Losses, first quarter of 2020; however, the CARES Act, issued in 2020, provided temporary relief related to the implementation of this accounting guidance until the earlier of the date on which the national emergency concerning the COVID-19 virus terminates or December 31, 2020. The Company has elected to utilize this relief and has calculated the allowance for loan losses and the resulting provision for loan losses using the prior incurred loss method at September 30, 2020. When the temporary relief expires the implementation of this accounting guidance is expected to be applied retroactively back to January 1, 2020. The Company completed the process of developing credit models and model implementation during the fourth quarter of 2019 and is in the final stages of implementing the internal controls, accounting, financial reporting and governance processes to comply with the new guidance. The adoption of CECL is expected to result in an increase to our total allowance for credit losses (ACL) on loans held for investment and will require a reclassification of purchased credit-impaired discount from loans to the allowance for credit losses. The expected increase in the ACL is largely attributable to the longer duration of the real estate portfolios. The ultimate impact to the Company’s financial condition and results of operations of the ASU, at both adoption and each subsequent reporting period, is highly dependent on credit quality, macroeconomic forecasts and conditions, the composition of our loan portfolio and other management judgements. In January 2017, the FASB issued ASU 2017-04, Intangibles-Goodwill and Other In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820) - Changes to the Disclosure Requirements for Fair Value Measurement In March 2020, various regulatory agencies, including the Federal Reserve and the Federal Deposit Insurance Corporation, (“the agencies”) issued an interagency statement on loan modifications and reporting for financial institutions working with customers affected by the Coronavirus. The interagency statement was effective immediately and impacted accounting for loan modifications. This interagency statement was later revised in April 2020 to clarify the interaction between the original interagency statement and section 4013 of the CARES Act, as well as the agencies’ views on consumer protection considerations. Under Accounting Standards Codification 310-40, Receivables – Troubled Debt Restructurings by Creditors In March 2020, the FASB issued ASU 2020-04, Facilitation of the Effects of Reference Rate Reform on Financial Reporting In October 2020, the FASB issued ASU 2020-08, Codification Improvements to Subtopic 310-20, Receivables-Nonrefundable Fees and Other Costs

During the third quarter of 2020, all held-to-maturity securities were moved to available-for-sale to better manage the Company’s assets and liabilities and to facilitate opportunities to take advantage of changes in the yield curve or other market factors. The fair value and amortized cost of debt securities at September 30, 2020, by contractual maturity, is shown below. Expected maturities will differ from contractual maturities because issuers may have the right to call or prepay obligations with or without call or prepayment penalties. Securities not due at a single maturity date, primarily mortgage-backed securities, are shown separately.

As of September 30, 2020, the Company held 38 available-for-sale securities in an unrealized loss position. Unrealized losses on securities have not been recognized into income because the security issuers are of high credit quality, management does not intend to sell, it is more likely than not that the Company will not be required to sell the securities prior to their anticipated recovery and the decline in fair value is largely due to changes in interest rates. The fair value is expected to recover as the securities approach maturity. There were no proceeds from sales of available-for-sale securities during the nine months ended September 30, 2020, or 2019.

The Company analyzes loans individually by classifying the loans as to credit risk. Consumer loans are considered pass credits unless downgraded due to payment status or reviewed as part of a larger credit relationship. Loans that participated in the short-term deferral program are not automatically considered classified solely due to a deferral, are subject to ongoing monitoring and will be downgraded or placed on nonaccrual if a noted weakness exists. The Company uses the following definitions for risk ratings. Pass: Special Mention Substandard Doubtful The risk category of loans by class of loans is as follows as of September 30, 2020, and December 31, 2019.

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	NOTE 4 – DERIVATIVE FINANCIAL INSTRUMENTS The Company is exposed to interest-rate risk primarily from the effect of interest rate changes on its interest-earning assets and its sources of funding these assets. The Company will periodically enter into interest rate swaps or interest rate caps/floors to manage certain interest rate risk exposure. Interest Rate Swaps Designated as Fair Value Hedges The Company periodically enters into interest rate swaps to hedge the fair value of certain commercial real estate loans. These transactions are designated as fair value hedges. In this type of transaction, the Company typically receives from the counterparty a variable-rate cash flow based on the one-month London Interbank Offered Rate (“LIBOR”) plus a spread to this index and pays a fixed-rate cash flow equal to the customer loan rate. At September 30, 2020, the portfolio of interest rate swaps had a weighted average maturity of 6.5 years, a weighted average pay rate of 5.19% and a weighted average rate received of 3.22%. At December 31, 2019, the portfolio of interest rate swaps had a weighted average maturity of 7.3 years, a weighted average pay rate of 5.19% and a weighted average rate received of 4.78%. Stand-Alone Derivatives The Company periodically enters into interest rate swaps with our borrowers and simultaneously enters into swaps with a counterparty with offsetting terms for the purpose of providing our borrowers long-term fixed rate loans. Neither swap is designated as a hedge and both are marked to market through earnings. At September 30, 2020, this portfolio of interest rate swaps had a weighted average maturity of 8.1 years, weighted average pay rate of 4.14% and a weighted average rate received of 4.14%. At December 31, 2019, this portfolio of interest rate swaps had a weighted average maturity of 8.8 years, weighted average pay rate of 4.92% and weighted average rate received of 4.92%. In 2009, the Company purchased an interest rate cap derivative to assist with interest-rate risk management. This was not designated as a hedging instrument but rather as a stand-alone derivative. During 2019, the interest rate cap derivative matured. Reconciliation of Derivative Fair Values and Gains/(Losses) The notional amount of a derivative contract is a factor in determining periodic interest payments or cash flows received or paid. The notional amount of derivatives serves as a level of involvement in various types of derivatives. The notional amount does not represent the Company’s overall exposure to credit or market risk, generally, the exposure is significantly smaller. The following table shows the notional balances and fair values (including net accrued interest) of the derivatives outstanding by derivative type at September 30, 2020, and December 31, 2019.

REGULATORY MATTERS	NOTE 8 – REGULATORY MATTERS Banks and bank holding companies (on a consolidated basis) are subject to regulatory capital requirements administered by federal banking agencies. Capital adequacy guidelines and, additionally for banks, prompt corrective action regulations, involve quantitative measures of assets, liabilities, and certain off-balance-sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators. Failure to meet capital requirements can initiate regulatory action. The final rules implementing the Basel Committee on Banking Supervision’s capital guidelines for U.S. banks (Basel III rules) became effective for the Company on January 1, 2015, and became fully phased in January 1, 2019. The Basel III rules require banks to maintain a Common Equity Tier 1 capital ratio of 6.5%, a total Tier 1 capital ratio of 8%, a total capital ratio of 10% and a leverage ratio of 5% to be deemed “well capitalized” for purposes of certain rules and prompt corrective action requirements. The risk-based ratios include a “capital conservation buffer” of 2.5% which can limit certain activities of an institution, including payment of dividends, share repurchases and discretionary bonuses to executive officers, if its capital level is below the buffer amount. Management believes as of September 30, 2020, the Company and Bank meet all capital adequacy requirements to which they are subject. Prompt corrective action regulations provide five classifications: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized, although these terms are not used to represent overall financial condition. If adequately capitalized, regulatory approval is required to accept brokered deposits. If undercapitalized, capital distributions are limited, as are asset growth and acquisitions, and capital restoration plans are required. As of September 30, 2020, the most recent notifications from the federal regulatory agencies categorized Equity Bank as well capitalized under the regulatory framework for prompt corrective action. To be categorized as well capitalized, Equity Bank must maintain minimum total risk-based, Tier 1 risk-based, and Tier 1 leverage ratios as set forth in the table below. There are no conditions or events since that notification that management believes have changed Equity Bank’s category. The Company’s and Equity Bank’s capital amounts and ratios at September 30, 2020, and December 31, 2019, are presented in the table below.

FAIR VALUE

Fair Value Disclosures [Abstract]
FAIR VALUE	NOTE 10 – FAIR VALUE The Company uses fair value measurements to record fair value adjustments to certain assets and liabilities and to disclose the fair value of its financial instruments. Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. For disclosure purposes, the Company groups its financial and non-financial assets and liabilities into three different levels based on the nature of the instrument and the availability and reliability of the information that is used to determine fair value. The three levels of inputs that may be used to measure fair values are defined as follows. Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. Level 2: Significant other observable inputs other than Level 1 prices such as 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. Level 3: Significant unobservable inputs that reflect a reporting entity’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. Level 1 inputs are considered to be the most transparent and reliable. The Company assumes the use of the principal market to conduct a transaction of each particular asset or liability being measured and then considers the assumptions that market participants would use when pricing the asset or liability. Whenever possible, the Company first looks for quoted prices for identical assets or liabilities in active markets (Level 1 inputs) to value each asset or liability. However, when inputs from identical assets or liabilities on active markets are not available, the Company utilizes market observable data for similar assets and liabilities. The Company maximizes the use of observable inputs and limits the use of unobservable inputs to occasions when observable inputs are not available. The need to use unobservable inputs generally results from the lack of market liquidity of the actual financial instrument or of the underlying collateral. Although, in some instances, third party price indications may be available, limited trading activity can challenge the implied value of those quotations. The following is a description of the valuation methodologies used for assets and liabilities measured at fair value, as well as the general classification of each instrument under the hierarchy. Fair Value of Assets and Liabilities Measured on a Recurring Basis The fair values of securities available-for-sale and equity securities with readily determinable fair value are carried at fair value on a recurring basis. To the extent possible, observable quoted prices in an active market are used to determine fair value and, as such, these securities are classified as Level 1. For securities where quoted prices are not available, fair values are calculated based on market prices of similar securities, generally determined by matrix pricing, which is a mathematical technique widely used in the industry to value securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities’ relationship to other benchmark quoted securities (Level 2 inputs). The Company’s available-for-sale securities, including U.S. Government sponsored entity securities, residential mortgage-backed securities (all of which are issued or guaranteed by government sponsored agencies), corporate securities, Small Business Administration securities, and State and Political Subdivision securities are classified as Level 2. The fair values of derivatives are determined based on a valuation pricing model using readily available observable market parameters such as interest rate yield curves (Level 2 inputs) adjusted for credit risk attributable to the seller of the interest rate derivative. Cash collateral received from or delivered to a derivative counterparty is classified as Level 1. Assets and liabilities measured at fair value on a recurring basis are summarized in the following table. September 30, 2020 (Level 1) (Level 2) (Level 3) Assets: Available-for-sale securities: U.S. Government-sponsored entities $ — $ 1,029 $ — Mortgage backed securities Government-sponsored residential mortgage backed securities — 604,870 — Private label residential mortgage backed securities — 21,084 — Corporate — 44,864 — Small Business Administration loan pools — 1,276 — State and political subdivisions — 125,453 — Derivative assets: Derivative assets (included in other assets) — 7,937 — Cash collateral held by counterparty and netting adjustments 102 — — Total derivative assets 102 7,937 — Other assets: Equity securities with readily determinable fair value 501 — — Total other assets 501 — — Total assets $ 603 $ 806,513 $ — Liabilities: Derivative liabilities: Derivative liabilities (included in other liabilities) $ — $ 9,299 $ — Cash collateral held by counterparty and netting adjustments (9,299 ) — — Total derivative liabilities (9,299 ) 9,299 — Total liabilities $ (9,299 ) $ 9,299 $ — December 31, 2019 (Level 1) (Level 2) (Level 3) Assets: Available-for-sale securities: Mortgage backed securities Government-sponsored redisential mortgage backed securities $ — $ 142,067 $ — Derivative assets: Derivative assets (included in other assets) — 3,535 — Cash collateral held by counterparty and netting adjustments 182 — — Total derivative assets 182 3,535 — Other assets: Equity securities with readily determinable fair value 489 — — Total other assets 489 — — Total assets $ 671 $ 145,602 $ — Liabilities: Derivative liabilities: Derivative liabilities (included in other liabilities) $ — $ 4,076 $ — Cash collateral held by counterparty (4,004 ) — — Total derivative liabilities (4,004 ) 4,076 — Total liabilities $ (4,004 ) $ 4,076 $ — There were no material transfers between levels during the nine months ended September 30, 2020, or the year ended December 31, 2019. The Company’s policy is to recognize transfers into or out of a level as of the end of a reporting period. Fair Value of Assets and Liabilities Measured on a Non-recurring Basis Certain assets are measured at fair value on a non-recurring basis when there is evidence of impairment. The fair value of impaired securities is determined as discussed previously for available-for-sale securities. The fair values of impaired loans with specific allocations of the allowance for loan losses are generally based on recent real estate appraisals of the collateral less estimated cost to sell. Declines in the fair values of other real estate owned subsequent to their initial acquisitions are also based on recent real estate appraisals less estimated selling costs. Real estate appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the appraisers to adjust for differences between the comparable sales and income data available. We routinely value loans other than real estate as multiples of earnings or with the discounted cash flow approach and adjustments are made to observable market data to make the valuation consistent with the underlying credit. Such adjustments made to real estate appraisals and other loan valuations are typically significant and result in a Level 3 classification of the inputs for determining fair value. Assets measured at fair value on a non-recurring basis are summarized below. September 30, 2020 (Level 1) (Level 2) (Level 3) Impaired loans: Commercial real estate $ — $ — $ 5,110 Commercial and industrial 5,193 — 6,979 Residential real estate — — 2,327 Agricultural real estate — — 4,680 Other — — 922 Other real estate owned: Commercial real estate — — 4,956 Residential real estate — — 671 December 31, 2019 (Level 1) (Level 2) (Level 3) Impaired loans: Commercial real estate $ — $ — $ 2,411 Commercial and industrial — — 15,688 Residential real estate — — 2,920 Agricultural real estate — — 866 Other — — 1,549 Other real estate owned: Commercial real estate — — 1,268 Residential real estate — — 42 The Company did not record any liabilities for which the fair value was measured on a non-recurring basis at September 30, 2020, or at December 31, 2019. Valuations of impaired loans and other real estate owned utilize third party appraisals or broker price opinions and were classified as Level 3 due to the significant judgment involved. Appraisals may include the utilization of unobservable inputs, subjective factors and quantitative data to estimate fair market value. The following table presents additional information about the unobservable inputs used in the fair value measurement of financial assets measured on a nonrecurring basis that were categorized with Level 3 of the fair value hierarchy.

COMMITMENTS AND CREDIT RISK	NOTE 11 – COMMITMENTS AND CREDIT RISK The Company extends credit for commercial real estate mortgages, residential mortgages, working capital financing and loans to businesses and consumers. Commitments to Originate Loans and Available Lines of Credit Commitments to originate loans and available lines of credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments and lines of credit generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since a portion of the commitments and lines of credit may expire without being drawn upon, the total commitment and lines of credit amounts do not necessarily represent future cash requirements. Each customer’s creditworthiness is evaluated on a case-by-case basis. The amount of collateral obtained, if deemed necessary, is based on management’s credit evaluation of the counterparty. Collateral held varies, but may include accounts receivable, inventory, property, plant and equipment, commercial real estate and residential real estate. Mortgage loans in the process of origination represent amounts that the Company plans to fund within a normal period of 60 to 90 days, and which are intended for sale to investors in the secondary market. The contractual amounts of commitments to originate loans and available lines of credit as of September 30, 2020, and December 31, 2019, were as follows. September 30, 2020 December 31, 2019 Fixed Rate Variable Rate Fixed Rate Variable Rate Commitments to make loans $ 50,686 $ 93,720 $ 41,916 $ 141,685 Mortgage loans in the process of origination 15,272 2,767 9,200 2,473 Unused lines of credit 86,836 168,516 95,866 150,749 The fixed rate loan commitments have interest rates ranging from 2.40% to 7.51% and maturities ranging from 1 month to 121 months. Standby Letters of Credit Standby letters of credit are irrevocable commitments issued by the Company to guarantee the performance of a customer to a third party once specified pre-conditions are met. Financial standby letters of credit are primarily issued to support public and private borrowing arrangements, including commercial paper, bond financing, and similar transactions. Performance standby letters of credit are issued to guarantee performance of certain customers under non-financial contractual obligations. The credit risk involved in issuing standby letters of credit is essentially the same as that involved in extending loans to customers. The contractual amounts of standby letters of credit as of September 30, 2020, and December 31, 2019, were as follows.

LEGAL MATTERS	NOTE 12 – LEGAL MATTERS The Company is party to various matters of litigation in the ordinary course of business. The Company periodically reviews all outstanding pending or threatened legal proceedings and determines if such matters will have an adverse effect on the business, financial condition or results of operations or cash flows. A loss contingency is recorded when the outcome is probable and reasonably able to be estimated. The following loss contingency has been identified by the Company as reasonably possible to result in an unfavorable outcome for the Company or the Bank. Equity Bank is a party to a February 3, 2015, lawsuit filed against it by CitiMortgage, Inc. (“Citi”). The lawsuit involves an alleged breach of contract related to loan repurchase obligations and damages of $2,700 plus pre-judgment and post-judgment interest. In January 2018 Except for the above-mentioned lawsuit, there are no other outstanding claims for potential repurchase or indemnification demands regarding mortgage loans originated by Equity Bank and sold to investors. However, the Company believes there is possible risk it may face similar demands based on comparable demands loan aggregators are facing from their investors, including Government Sponsored Entities such as Freddie Mac and Fannie Mae, and or settlement agreements loan aggregators have entered into with those investors. The amount of potential loss and outcome of such possible litigation, if it were commenced, is uncertain and the Company would vigorously contest any claims. On May 13, 2019, a purported stockholder of the Company filed a putative securities class action lawsuit in federal court in the Southern District of New York against the Company and certain of its executive officers. On August 16, 2019, the court appointed lead plaintiffs and on October 15, 2019, the plaintiffs filed an amended complaint on behalf of a putative class of persons who purchased Company securities between April 20, 2018, and April 23, 2019. Plaintiffs allege that the Company made materially misleading statements about the Company’s financial results, business, operations and prospects starting on April 20, 2018, that these statements caused the Company’s securities to be overvalued and that the “truth” came out on January 24, 2019, when the Company disclosed that a credit relationship was downgraded and further on April 22, 2019, when the Company disclosed a $14,500 provision for loan loss against that credit relationship. On December 6, 2019, the Company filed a motion to dismiss all claims in the lawsuit. On October 14, 2020, the court issued a ruling in favor of the Company finding that the case had no merit and dismissing all claims with prejudice. The plaintiffs have 30 days to appeal the adverse ruling. At this time, the Company is confident the outcome will be resolved in favor of the Company.

Subsequent Events [Abstract]
SUBSEQUENT EVENTS	NOTE 14 – SUBSEQUENT EVENTS On October 22, 2020, the Federal Reserve Bank of Kansas City advised the Company that it had no objection to the Company’s authorization of its repurchase of up to 800,000 shares of the Company’s Class A Voting Common Stock, par value $0.01 per share, from time to time, beginning October 30, 2020, and concluding October 29, 2021. This follows the completion of a previously authorized 2019 repurchase program in which the Company repurchased 1,100,000 shares at a total cost of $23,695, or an average of $21.54 per share. The Company may repurchase shares in privately negotiated transactions, in the open market, including pursuant to any trading plan that may be adopted in accordance with Rule 10b5-1 promulgated by the Securities and Exchange Commission, or otherwise in a manner that complies with applicable federal securities laws. The repurchase program does not obligate the Company to acquire a specific dollar amount or number of shares and it may be extended, modified or discontinued at any time without notice. At the close of business on October 23, 2020, Equity Bank acquired the assets and assumed the deposit liabilities of Almena State Bank (“ASB”), with locations in Almena and Norton, Kansas, pursuant to a Purchase and Assumption Agreement facilitated by the Federal Deposit Insurance Corporation. Information necessary to recognize the fair value of assets acquired and liabilities assumed remains incomplete. At September 30, 2020, ASB reported total assets of $ 65,733 , which includes total loans of $ 49,855 and securities of $ 7,412 . Total deposit liabilities reported were $ 64,941 .

Organization Consolidation And Presentation Of Financial Statements [Abstract]
Reclassifications	Reclassifications Some items in prior financial statements were reclassified to conform to the current presentation. Management determined the items reclassified are immaterial to the consolidated financial statements taken as a whole and did not result in a change in equity or net income for the periods reported. Risk and Uncertainties The outbreak of COVID-19 has adversely impacted a broad range of industries in which the Company’s customers operate and could impair their ability to fulfill their financial obligations to the Company. The World Health Organization has declared COVID-19 to be a global pandemic indicating that almost all public commerce and related business activities must be, to varying degrees, curtailed with the goal of decreasing the rate of new infections. The spread of the outbreak has caused significant disruptions in the U.S. economy and has disrupted banking and other financial activity in the areas in which the Company operates. While there has been no material impact to the Company’s employees to date, COVID-19 could also potentially create widespread business continuity issues for the Company. Congress, the President, and the Federal Reserve have taken several actions designed to cushion the economic fallout. Most notably, the CARES Act was signed into law at the end of March 2020 as a $2 trillion legislative package. The goal of the CARES Act is to prevent a severe economic downturn through various measures, including direct financial aid to American families and economic stimulus to significantly impacted industry sectors. The package also includes extensive emergency funding for hospitals and medical providers. In addition to the general impact of COVID-19, certain provisions of the CARES Act as well as other recent legislative and regulatory relief efforts are expected to have a material impact on the Company’s operations. The Company’s business is dependent upon the willingness and ability of its employees and customers to conduct banking and other financial transactions. If the global response to contain COVID-19 is unsuccessful, the Company could experience a material adverse effect on its business, financial condition, results of operations and cash flows. While it is not possible to know the full universe or extent that the impact of COVID-19, and resulting measures to curtail its spread, will have on the Company’s operations, the Company is disclosing potentially material items of which it is aware. Financial position and results of operations The Company’s interest income and fees could be reduced due to COVID-19. In keeping with guidance from regulators, the Company is actively working with COVID-19 affected borrowers to defer their payments, interest, and fees. While interest and fees will still accrue to income, through normal GAAP accounting, should eventual credit losses on these deferred payments emerge, interest income and fees accrued would need to be reversed. In such a scenario, interest income in future periods could be negatively impacted. At this time, the Company is unable to project the materiality of such an impact but recognizes the breadth of the economic impact may affect its borrowers’ ability to repay in future periods. Capital and liquidity As of September 30, 2020, all our capital ratios, and our subsidiary bank’s capital ratios, were in excess of regulatory requirements. While we are currently classified as well capitalized, an extended economic recession brought about by COVID-19 could adversely impact our reported and regulatory capital ratios by further credit losses. The Company relies on cash on hand as well as dividends from its subsidiary bank to service its debt. If the Company’s subsidiary bank’s capital deteriorates such that it is unable to pay dividends to the Company for an extended period of time, the Company may not be able to service its debt. The Company maintains access to multiple sources of liquidity. Wholesale funding markets have remained open to us, but rates for short term funding have historically been volatile. If funding costs are elevated for an extended period of time, it could have an adverse effect on the Company’s net interest margin. If an extended recession caused large numbers of the Company’s deposit customers to withdraw their funds, the Company might become more reliant on volatile or more expensive sources of funding. Asset valuation Currently, the Company does not expect COVID-19 to affect its ability to account timely for the assets on its balance sheet; however, this could change in future periods. While certain valuation assumptions and judgments will change to account for pandemic-related circumstances such as widening credit spreads, the Company does not anticipate significant changes in methodology used to determine the fair value of assets measured in accordance with GAAP. At September 30, 2020, the Company performed a quantitative analysis to assess goodwill for impairment of Equity Bancshares, Inc., the sole reporting unit. Consideration was given to the on-going economic market disruption, the movement of the Company’s stock price in relation to other bank indexes and the length of time that the market value of the reporting unit has been below its book value as triggering events and completed a quantitative analysis to assess whether or not goodwill was impaired. This analysis determined that goodwill was impaired and subsequently the Company booked a non-cash impairment charge of $104,831 to goodwill on September 30, 2020. The determination of the fair value of the reporting unit incorporates assumptions that marketplace participants would use in their estimates of fair value in a change in control transaction, as prescribed by ASC Topic 820. To arrive at a conclusion of fair value, we utilized both the income approach and the market approach and then applied weighting factors to each approach. Weighting factors represent our best business judgement of the weightings a market participant would utilize in arriving at fair value of the reporting unit. In performing the analysis, Company management made numerous assumptions with respect to industry performance, reporting unit business performance, economic and market conditions and various other matters, many of which require significant management judgement. Projections related to business unit performance over the next five years assumed an economic downturn over a 12-month time horizon subsequently returning to conservative positive growth rates in loan and deposits after that time period. The analysis performed and the assumptions that are incorporated into the analysis reflect the best currently available estimates and judgements as to the expected future financial performance of the reporting unit. At September 30, 2020, the Company had goodwill of $31,601 which could be at risk of further impairment with further declines in performance, stock price or market conditions for bank stocks. Processes, controls and business continuity plan As of September 30, 2020, all the Company’s bank locations were open to customers with social distancing measures in place, allowing full access for customer use. Customers are served by appointment, calling ahead, curbside and drive-through but offered full lobby access during normal hours. The Company does not anticipate incurring additional material cost related to its continued deployment of the preparedness plan and no material operational or internal control challenges or risks have been identified to date. The Company does not anticipate significant challenges to its ability to maintain its systems and controls in light of the measures the Company has taken to prevent the spread of COVID-19. The Company has not experienced any material resource constraints through the implementation of its business continuity plans. Lending operations and accommodations to borrowers In keeping with regulatory guidance to work with borrowers during this unprecedented situation and as outlined in the CARES Act, the Company has worked with customers affected by COVID-19 and offered short-term assistance in accordance with regulatory guidelines. Commercial borrowers needing assistance have been offered either a 90-day principal and interest deferral or a 180-day principal only deferral. Commercial borrowers that originally requested a 90-day deferral can request an additional 90-day deferral by providing their previous year financial information, current year interim financial information, projections for the balance of the calendar year and information related to their cash reserves to show a need for the additional 90-day deferral. Consumers needing assistance have been offered a 90-day principal and interest deferral with an option to request an additional 90-day deferral. At the end of the deferral period, the interest will be capitalized and the loan re-amortized generally causing a minimal increase to payments for most consumers. As of September 30, 2020, the Company had 68 remaining deferrals on outstanding loan balances of $41,228, with interest deferred of $306. In accordance with interagency guidance issued in March 2020, these short-term deferrals are not automatically considered troubled debt restructurings, are not reflected in past due loan balances and have not been reported as a classified loan solely due to a deferral. These deferred loans are subject to ongoing monitoring and will be downgraded or placed on nonaccrual if a noted weakness exists. The following table lists loans by category that have been deferred under the payment deferral program at September 30, 2020. September 30, 2020 Commercial real estate $ 4,965 Commercial and industrial 25,746 Residential real estate 9,752 Agricultural real estate 643 Consumer 122 Total loans $ 41,228 With the passage of the Paycheck Protection Program (“PPP”), administered by the Small Business Administration (“SBA”), the Company actively participated in assisting its customers with applications for resources through the program. PPP loans originated prior to June 5, 2020, have a two-year five-year Credit As a result of the current economic environment caused by the COVID-19 virus, the Company is engaging in frequent communication with borrowers to better understand their situation and the challenges faced, allowing the Company to respond proactively as needs and issues arise. Should economic conditions worsen, the Company could experience further increases in its required allowance for loan losses and record additional provision for loan losses. It is possible that the Company’s asset quality measures could worsen at future measurement periods if the effects of COVID-19 are prolonged. Many industries have and will continue to experience adverse impacts as a result of COVID-19. Our exposure from outstanding loans and commitments to industries which we consider a higher risk totaled approximately $285,943 in hospitality and $65,088 in aircraft manufacturing.
Adoption of New Accounting Standards	Recent Accounting Pronouncements In June 2016, FASB issued ASU 2016-13, Financial Instruments – Credit Losses, first quarter of 2020; however, the CARES Act, issued in 2020, provided temporary relief related to the implementation of this accounting guidance until the earlier of the date on which the national emergency concerning the COVID-19 virus terminates or December 31, 2020. The Company has elected to utilize this relief and has calculated the allowance for loan losses and the resulting provision for loan losses using the prior incurred loss method at September 30, 2020. When the temporary relief expires the implementation of this accounting guidance is expected to be applied retroactively back to January 1, 2020. The Company completed the process of developing credit models and model implementation during the fourth quarter of 2019 and is in the final stages of implementing the internal controls, accounting, financial reporting and governance processes to comply with the new guidance. The adoption of CECL is expected to result in an increase to our total allowance for credit losses (ACL) on loans held for investment and will require a reclassification of purchased credit-impaired discount from loans to the allowance for credit losses. The expected increase in the ACL is largely attributable to the longer duration of the real estate portfolios. The ultimate impact to the Company’s financial condition and results of operations of the ASU, at both adoption and each subsequent reporting period, is highly dependent on credit quality, macroeconomic forecasts and conditions, the composition of our loan portfolio and other management judgements. In January 2017, the FASB issued ASU 2017-04, Intangibles-Goodwill and Other In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820) - Changes to the Disclosure Requirements for Fair Value Measurement In March 2020, various regulatory agencies, including the Federal Reserve and the Federal Deposit Insurance Corporation, (“the agencies”) issued an interagency statement on loan modifications and reporting for financial institutions working with customers affected by the Coronavirus. The interagency statement was effective immediately and impacted accounting for loan modifications. This interagency statement was later revised in April 2020 to clarify the interaction between the original interagency statement and section 4013 of the CARES Act, as well as the agencies’ views on consumer protection considerations. Under Accounting Standards Codification 310-40, Receivables – Troubled Debt Restructurings by Creditors In March 2020, the FASB issued ASU 2020-04, Facilitation of the Effects of Reference Rate Reform on Financial Reporting In October 2020, the FASB issued ASU 2020-08, Codification Improvements to Subtopic 310-20, Receivables-Nonrefundable Fees and Other Costs
Revenue Recognition	The majority of the Company’s revenues come from interest income on financial instruments, including loans, leases, securities and derivatives, which are outside the scope of ASC 606.
