Basis of Presentation	NOTE 1 – BASIS OF PRESENTATION The interim consolidated financial statements include the accounts of Equity Bancshares, Inc., its wholly owned subsidiary, Equity Bank (“Equity Bank”) and Equity Bank’s wholly owned subsidiary, 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 generally accepted accounting principles for interim financial information. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial information. 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, 2014. Operating results for nine months ended September 30, 2015 are not necessarily indicative of the results that may be expected for the year ending December 31, 2015 or any other period.

The fair value and amortized cost of debt securities at September 30, 2015, by contractual maturity, is shown below.

The table above presents unrealized losses on held-to maturity securities since the date of the securities purchases, independent of the impact associated with changes in cost basis upon transfer from the available-for-sale designation to the held-to-maturity designation. 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 and 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. The proceeds from sales and the associated gains and losses reclassified from other comprehensive income to income are listed below: Three Months Ended September 30, 2015 2014 Proceeds $ — $ 20,685 Gross gains — 631 Gross losses — — Income tax expense on net realized gains — 241 Nine Months Ended September 30, 2015 2014 Proceeds $ 17,105 $ 23,460 Gross gains 370 725 Gross losses — — Income tax expense on net realized gains 142 277

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. The Company uses the following definitions for risk ratings: Special Mention Substandard: Doubtful: The risk category of loans by class of loans is as follows as of September 30, 2015 and December 31, 2014: September 30, 2015 Pass Special Substandard Doubtful Total Commercial real estate $ 359,760 $ — $ 11,728 $ — $ 371,488 Commercial and industrial 252,816 — 2,110 307 255,233 Residential real estate 181,813 — 1,962 — 183,775 Agricultural real estate 17,701 — 403 — 18,104 Consumer 10,800 — 26 — 10,826 Agricultural 15,511 — 117 — 15,628 Total $ 838,401 $ — $ 16,346 $ 307 $ 855,054 December 31, 2014 Pass Special Substandard Doubtful Total Commercial real estate $ 340,224 $ 147 $ 23,096 $ — $ 363,467 Commercial and industrial 181,272 — 1,828 — 183,100 Residential real estate 132,285 — 2,170 — 134,455 Agricultural real estate 16,708 — 375 — 17,083 Consumer 7,846 — 29 — 7,875 Agricultural 15,432 — 3,835 — 19,267 Total $ 693,767 $ 147 $ 31,333 $ — $ 725,247 Purchased Credit Impaired Loans As part of previous acquisitions, the Company has acquired certain loans, for which there was, at acquisition, evidence of deterioration of credit quality since origination and it was probable, at acquisition, that all contractually required payments would not be collected.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	NOTE 4 – DERIVATIVE FINANCIAL INSTRUMENTS Net cash settlements on derivatives that qualify for hedge accounting are recorded in interest income or interest expense, based on the item being hedged. Net cash settlements on derivatives that do not qualify for hedge accounting are reported in non-interest income. Cash flows on hedges are classified in the cash flow statement the same as the cash flows of the items being hedged unless the derivative meets the criteria to be a financing derivative. All derivatives are recognized in the consolidated balance sheet at their fair values and are reported as either derivative assets or derivative liabilities net of accrued net settlements and collateral, if any. The individual derivative amounts are netted by counterparty when the netting requirements have been met. If these netted values are positive, they are classified as an asset and, if negative, they are classified as a liability. The Company formally documents the relationship between derivatives and hedged items, as well as the risk-management objective and the strategy for undertaking hedge transactions at the inception of the hedging relationship. This documentation includes linking fair value or cash flow hedges to specific assets and liabilities on the balance sheet or to specific firm commitments or forecasted transactions. The Company also formally assesses, both at the hedge’s inception and on an ongoing basis (at least quarterly), whether the derivative instruments that are used are highly effective in offsetting changes in fair values or cash flows of the hedged items. The Company discontinues hedge accounting when it determines that the derivative is no longer effective in offsetting changes in the fair value or cash flows of the hedged item, the derivative is settled or terminates, a hedged forecasted transaction is no longer probable, a hedged firm commitment is no longer firm, or treatment of the derivative as a hedge is no longer appropriate or intended. When hedge accounting is discontinued, subsequent changes in fair value of the derivative are recorded as non-interest income. When a fair value hedge is discontinued, the hedged asset or liability is no longer adjusted for changes in fair value and the existing basis adjustment is amortized or accreted over the remaining life of the asset or liability. When a cash flow hedge is discontinued but the hedged cash flows or forecasted transactions are still expected to occur, gains or losses that are accumulated in other comprehensive income are amortized into earnings over the same periods which the hedged transactions will effect earnings. 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, 2015, the portfolio of interest rate swaps have a weighted average maturity of 10.2 years, a weighted average pay rate of 4.45% and a weighted average rate received of 2.92%. No interest rate swaps were outstanding at December 31, 2014. Stand-Alone Derivatives: In 2009, the Company purchased an interest rate cap derivative to assist with interest rate risk management. This derivative is not designated as a hedging instrument but rather as a stand-alone derivative. At September 30, 2015, the interest rate cap had a term of 4.1 years and a cap rate of 4.50%. At December 31, 2014, the interest rate cap had a term of 4.9 years and a cap rate of 4.50% 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, 2015 and December 31, 2014: September 30, 2015 December 31, 2014 Notional Derivative Derivative Notional Derivative Derivative Derivatives designated as hedging instruments: Interest rate swaps $ 12,341 $ — $ 361 $ — $ — $ — Total derivatives designated as hedging relationships 12,341 — 361 — — — Derivatives not designated as hedging instruments: Interest rate caps/floors 3,206 2 — 3,399 11 — Total derivatives not designated as hedging instruments 3,206 2 — 3,399 11 — Total $ 15,547 2 361 $ 3,399 11 — Cash Collateral — (270 ) — — Net amount presented in Balance Sheet $ 2 $ 91 $ 11 $ — For the three months ended September 30, 2015 and 2014, the Company recorded net losses on derivatives and hedging activities: 2015 2014 Derivatives designated as hedging instruments: Interest rate swaps $ — $ — Total net gain (loss) related to fair value hedge ineffectiveness — — Derivatives not designated as hedging instruments: Economic hedges: Interest rate caps/floors (3 ) (2 ) Total net gains (losses) related to derivatives not designated as hedging instruments (3 ) (2 ) Net gains (losses) on derivatives and hedging activities $ (3 ) $ (2 ) For the nine months ended September 30, 2015 and 2014, the Company recorded net losses on derivatives and hedging activities: 2015 2014 Derivatives designated as hedging instruments: Interest rate swaps $ — $ — Total net gain (loss) related to fair value hedge ineffectiveness — — Derivatives not designated as hedging instruments: Economic hedges: Interest rate caps/floors (9 ) (28 ) Total net gains (losses) related to derivatives not designated as hedging instruments (9 ) (28 ) Net gains (losses) on derivatives and hedging activities $ (9 ) $ (28 ) The following table shows the recorded net gains (losses) on derivatives and the related hedged items in fair value hedging relationships and the impact of those derivatives on the Company’s net interest income for the three months ended September 30, 2015.

Regulatory Matters	NOTE 7 – REGULATORY MATTERS Banks and bank holding companies 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. The Company and Equity Bank have elected to exclude accumulated other comprehensive income items in computing regulatory capital. Capital amounts and classifications are also subject to qualitative judgments by regulators. Failure to meet capital requirements can initiate regulatory action. Management believes as of September 30, 2015, the Company and Equity 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. To be categorized as well capitalized, Equity Bank must maintain minimum total risk-based, Tier 1 risk-based, Common equity Tier 1 risk-based and Tier 1 leverage ratios as set forth in the table. The most recent notification from the regulatory banking agencies categorized Equity Bank as “well capitalized” under the regulatory capital framework for prompt corrective action and there have been no events since that notification that the Company believes have changed Equity Bank’s category. In July 2013, the federal banking agencies published final rules establishing a new comprehensive capital framework for U.S. banking organizations. These rules became effective as applied to the Company and Equity Bank on January 1, 2015. An additional ratio, common equity Tier 1 capital to risk weighted assets, was added by these new rules. The Company’s and Equity Bank’s capital amounts and ratios at September 30, 2015 (under the new rules) and December 31, 2014 (under the previous rules) are presented in the tables below. Ratios provided for Equity Bancshares, Inc. represent the ratios of the Company on a consolidated basis.

Fair Value Disclosures [Abstract]
Fair Value	NOTE 9 – 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 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 agencies, residential mortgage-backed securities (all of which are issued or guaranteed by government sponsored agencies), corporate securities, Small Business Administration securities, State and Political Subdivision securities, and equity securities are classified as level 2. The fair values of interest rate swaps and interest rate caps are determined based on valuation pricing models 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 below: September 30, 2015 (Level 1) (Level 2) (Level 3) Assets: Available-for-sale securities: U.S. government-sponsored entities $ — $ 17,124 $ — Residential mortgage-backed securities (issued by government-sponsored entities) — 88,469 — Corporate — 3,008 — Small Business Administration loan pools — 297 — State and political subdivisions — 509 — Equity securities — 499 — Interest rate caps (included in other assets) — 2 — Liabilities: Interest rate swaps (included in other liabilities) — 361 — Cash collateral held by counterparty (270 ) — — Total derivative liabilities (270 ) 361 — December 31, 2014 (Level 1) (Level 2) (Level 3) Assets: Available-for-sale securities: U.S. government-sponsored entities $ — $ 10,400 $ — Residential mortgage-backed securities (issued by government-sponsored entities) — 36,529 — Corporate — 3,011 — Small Business Administration loan pools — 356 — State and political subdivisions — 2,193 — Equity securities — 496 — Interest rate caps (included in other assets) — 11 — The Company did not record any liabilities for which the fair value was measured on a recurring basis at December 31, 2014. There were no transfers between Levels during the nine months ended September 30, 2015 or the year ended December 31, 2014. 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 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 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. Such adjustments 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 20, 2015 (Level 1) (Level 2) (Level 3) Impaired loans: Commercial real estate $ — $ — $ 3,125 Commercial and industrial — — 603 Residential real estate — — 813 Other — — 24 Other real estate owned: Commercial real estate — — 524 Residential real estate — — 540 December 31, 2014 (Level 1) (Level 2) (Level 3) Impaired loans: Commercial real estate $ — $ — $ 4,386 Commercial and industrial — — 663 Residential real estate — — 801 Other — — 158 Other real estate owned: Commercial real estate — — 524 Residential real estate — — 646 The Company did not record any liabilities for which the fair value was measured on a non-recurring basis at September 30, 2015 or at December 31, 2014. Valuations of impaired loans and other real estate owned utilize third party appraisals or broker price opinions, and are classified as Level 3 due to the significant judgment involved. Appraisals may include the utilization of unobservable inputs, subjective factors, and utilize 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: Fair Value Valuation Technique Unobservable Input Range (weighted September 30, 2015 Impaired loans $ 4,565 Sales Comparison Approach Adjustments for differences between comparable sales 6% - 29% (17%) December 31, 2014 Impaired loans $ 6,008 Sales Comparison Approach Adjustments for differences between comparable sales 3% - 15% (7%) Measurable inputs for other real estate owned are not material.

Legal Matters	NOTE 11 – 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 contingencies have 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. 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. At this early stage of the litigation it is difficult to estimate any potential loss, however Equity Bank believes it has numerous and meritorious defenses to the claims and anticipates contesting the matter vigorously. The Company currently does not believe that it is probable that this legal matter will result in an unfavorable outcome for the Company or Equity Bank. Equity Bank and U.S. Bank (“USB”) were parties to lawsuits filed against each other. These lawsuits involved loan-repurchase demands made by USB and allegations by Equity Bank that USB withheld servicing release premiums (profits) on loans sold by Equity Bank to USB, and also that USB had interfered with a 2012 business combination. In June 2015, Equity Bank and USB settled the lawsuits filed against each other. Except for the above mentioned lawsuit and settlement, there have been no other 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.

Subsequent Events [Abstract]
Subsequent Events	NOTE 12 – SUBSEQUENT EVENTS On July 27, 2015, the Company entered into a definitive agreement to acquire First Independence Corporation and its subsidiary, First Federal Savings & Loan of Independence, based in Independence, Kansas. The acquisition was completed on October 9, 2015 for aggregate cash consideration of $14,740 and First Federal Savings & Loan of Independence was merged into Equity Bank. The estimated fair values of assets acquired as of the acquisition date are $134,000; which include total loans valued at $89,962; securities of $29,355; core deposit intangible of $735 and goodwill of $570. The estimated fair values of liabilities assumed as of the acquisition date are $119,420; which include deposits of $87,251 and Federal Home Loan Bank advances of $31,603. Although the Company does not expect significant differences from estimated values, final valuations are not yet available. Goodwill is calculated as the excess of the cash consideration transferred over the net of the acquisition-date fair values of identifiable assets acquired and liabilities assumed. Goodwill is not expected to be deductible for tax purposes. The Company has incurred expenses related to the acquisition of approximately $1,691. For the three and nine month periods ended September 30, 2015, merger expenses totaled $77. On November 16, 2015, the Company completed an initial public offering of 2,231,000 shares of Class A common stock, $0.01 par value, at a price to the public of $22.50 per share, including 291,000 shares pursuant to the full exercise by the underwriters of their option to purchase additional shares of Class A common stock from the Company. The Company sold 1,941,000 shares of its Class A common stock and the selling stockholders named in the registration statement sold 290,000 shares of the Company’s Class A common stock (which included 273,000 shares of Class A common stock that were issued upon the automatic conversion of an equal number of shares of Class B common stock as a result of the offering). Gross proceeds paid to the Company were $43,673. The Company’s net proceeds are expected to be approximately $39,184 after the subtraction of underwriting discounts and commissions and estimated offering expenses, which are not yet finalized. All of the shares issued and sold in the initial public offering were registered under the Securities Act pursuant to a Registration Statement on Form S-1 (File No. 333-207351), which was declared effective by the SEC on November 10, 2015. Proceeds from the initial public offering will be used for on-going operating expense, to redeem the Series C preferred stock and to repay the bank stock loan.
