Re: Registration Statement on Form S-3

Ladies and Gentlemen:

We have acted as special counsel to Equity Bancshares, Inc., a Kansas corporation (the “Company”), with respect to certain legal matters in connection with the registration under the Securities Act of 1933, as amended (the “Securities Act”), of the offer and sale by the Company from time to time, pursuant to Rule 415 under the Securities Act, of (i) debt securities of the Company (“Debt Securities”), in one or more series, which may be senior debt securities or subordinated debt securities, and convertible into or exchangeable for Preferred Stock or Common Stock (both as defined below), (ii) Class A common stock of the Company, par value $0.01 per share (“Common Stock”), (iii) preferred stock of the Company (“Preferred Stock,” and together with Common Stock, “Company Stock”), in one or more series, which may be convertible into or exchangeable for Debt Securities or Common Stock, (iv) depositary shares (“Depositary Shares”) representing an interest in a fractional share or multiple shares of Preferred Stock, (v) warrants to purchase Debt Securities or shares of Company Stock (“Warrants”), (vi) subscription rights to the holders of Common Stock or other securities to purchase a specified number of shares of Common Stock or other securities (“Subscription Rights”) that the holder owns as of a record date set by the Board of Directors of the Company (the “Board”), and (vii) units that include Debt Securities, Common Stock, Preferred Stock, Depositary Shares, Warrants, Subscription Rights or any combination thereof (“Units”), having an aggregate initial offering price not to exceed $150,000,000, and each on terms to be determined at the time of its offering. The Debt Securities, Company Stock, Depositary Shares, Warrants, Subscription Rights and Units are collectively referred to herein as the “Securities.”

We also have participated in the preparation of the Prospectus (the “Prospectus”) contained in the Registration Statement on Form S-3 (the “Registration Statement”) to which this opinion is an exhibit. The Securities will be offered in amounts, at prices and on terms to be determined in light of market conditions at the time of sale and to be set forth in supplements (each, a “Prospectus Supplement”) to the Prospectus contained in the Registration Statement. Capitalized terms not defined herein shall have the meanings ascribed to them in the Prospectus.

The Debt Securities are to be issued under an Indenture, between the Company and Wells Fargo Bank, National Association, as trustee, a form of which has been filed as Exhibit 4.4 (in the case of senior Debt Securities) (the “Indenture”) or Exhibit 4.5 (in the case of subordinated Debt Securities) (the “Subordinated Indenture”) to the Registration Statement.

The opinions set forth above are subject to the effects of (i) bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and other similar laws relating to or affecting the enforcement of creditors’ rights generally; (ii) general equitable principles (whether considered in a proceeding in equity or at law); (iii) an implied covenant of good faith and fair dealing; (iv) provisions of law that require that a judgment for money damages rendered by a court in the United States be expressed only in United States dollars; (v) limitations by any governmental authority that limit, delay or prohibit the making of payments outside the United States; and (vi) generally applicable laws that (a) provide for the enforcement of oral waivers or modifications where a material change of position in reliance thereon has occurred or provide that a course of performance may operate as a waiver, (b) limit the availability of a remedy under certain circumstances where another remedy has been elected, (c) limit the enforceability of provisions releasing, exculpating or exempting a party from, or requiring indemnification of a party for, liability for its own action or inaction, to the extent the action or inaction involves negligence, gross negligence, recklessness, willful misconduct or unlawful conduct, (d) may, where less than all of a contract may be unenforceable, limit the enforceability of the balance of the contract to circumstances in which the unenforceable portion is not an essential part of the agreed-upon exchange, (e) may limit the enforceability of provisions providing for compounded interest, imposing increased interest rates or late payment charges upon delinquency in payment or default or providing for liquidated damages or for premiums or penalties upon acceleration, or (f) limit the waiver of rights under usury laws. Furthermore, the manner in which any particular issue relating to the opinions would be treated in any actual court case would depend in part on facts and circumstances particular to the case and would also depend on how the court involved chose to exercise the wide discretionary authority generally available to it. We express no opinion as to the effect of Section 210(p) of the Dodd-Frank Wall Street Reform and Consumer Protection Act.

We express no opinions concerning (i) the validity or enforceability of any provisions contained in the indenture, subordinated indenture or any supplemental indenture that purport to waive or not give effect to rights to notices, defenses, subrogation or other rights or benefits that cannot be effectively waived under applicable law; (ii) any provision that relates to severability or separability or purports to require that all amendments, supplements or waivers be in writing; or (iii) the enforceability of indemnification provisions to the extent they purport to relate to liabilities resulting from or based upon negligence or any violation of federal or state securities or blue sky laws.

The foregoing opinions are limited to the laws of the State of New York and the federal securities laws of the United States of America, and we are expressing no opinion as to the effect of the laws of any other jurisdiction, domestic or foreign.
