This Registration Statement on Form S-8 (this "***Registration Statement***") is being filed by Expion360 Inc., a Nevada corporation (the "***Registrant***"), to register shares of its common stock, par value $0.001 per share (the "***Common Stock***"), as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• an
 additional 489,086 shares of Common Stock reserved for issuance under the Expion360 Inc.

**Item 4.** **Description of Securities.**

Not applicable.

**Item 5.** **Interests of Named Experts and Counsel.**

Not applicable.

**Item 6.** **Indemnification of Directors and Officers.**

Subsection (1) of Section 78.7502 of the Nevada General Corporation Law (the "***NGCL***") empowers a corporation to indemnify any person who was or is a party, or is threatened to be made a party, to any threatened, pending, or completed action, suit, or proceeding, whether civil, criminal, administrative, or investigative (other than an action by or in the right of the corporation) by reason of the fact that the person is or was a director, officer, employee, or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust, or other enterprise, against expenses (including attorneys' fees, judgments, fines, and amounts paid in settlement) actually and reasonably incurred by him or her in connection with the action, suit, or proceeding if the person (i) exercised their powers in good faith under NGCL 78.138, or (ii) acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to, the best interests of the corporation and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful.

Subsection (2) of Section 78.7502 of the NGCL empowers a corporation to indemnify any person who was or is a party, or is threatened to be made a party, to any threatened, pending, or completed action or suit by or in the right of the corporation, to procure a judgment in its favor by reason of the fact that such person acted in any of the capacities set forth in subsection (1) above, against expenses (including attorneys' fees and amounts paid in settlement) actually and reasonably incurred by him or her in connection with the defense or settlement of such action or suit if the person (i) exercised their powers in good faith under NGCL 78.138, or (ii) acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to, the best interests of the corporation, except that no indemnification may be made in respect to any claim, issue, or matter as to which such person shall have been adjudged to be liable to the corporation, unless, and only to the extent that, the court in which such action or suit was brought determines that, in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnify for such expenses which the court shall deem proper.

Subsection (3) of Section 78.7502 of the NGCL provides that any discretionary indemnification pursuant to Section 78.7502 of the NGCL may be made by the corporation only as authorized in each specific case upon the determination that the indemnification of a director, officer, employee or agent of a corporation is proper under the circumstances.

The Registrant's Articles of Incorporation, as amended (the "***Articles***"), permits the Registrant to indemnify its directors and officers in the same manner as prescribed by the laws of the State of Nevada against expenses (including attorneys' fees, judgments, fines and amounts paid in settlement) actually and reasonably incurred by him or her in connection with such action, suit or proceeding related to their services as officers or directors. In addition, the Articles provide that the Registrant must pay the expenses of officers and directors incurred in defending a civil or criminal action, suit or proceeding as they are incurred and in advance of the final disposition of the action, suit or proceeding, upon receipt of an undertaking by or on behalf of the director or officer to repay the amount if it is ultimately determined by a court of competent jurisdiction that he or she is not entitled to be indemnified by the Registrant. Such right of indemnification shall not be exclusive of any other right which such officers or directors may have. Further, the Articles provide that the Registrant's board of directors may cause it to purchase and maintain insurance on behalf of any person who is or was a director or officer. The indemnification provided in the Articles shall continue as to a person who has ceased to be an officer or director, and shall inure to the benefit of the heirs, executors and administrators of any such person

The Registrant's Amended and Restated Bylaws provide that each officer or director who was or is a party to, or is threatened to be made a party to, or is otherwise involved in, any Proceeding (defined as any threatened, pending, or completed action, suit or proceeding, whether civil, criminal, administrative, or investigative), by reason of the fact that he or she is or was a director or officer of the Registrant or a director or officer or an affiliate of a predecessor corporation or member, manager or managing member of a predecessor limited liability company or affiliate of such limited liability company or is or was serving in any capacity at the request of the Registrant as a director, officer employee, agent, partner, member, manager or fiduciary or, or in any other capacity for, another corporation or any partnership, joint venture, limited liability company, trust, or other enterprise (an "***Indemnitee***") shall be indemnified and held harmless by the Registrant to the fullest extent permitted by Nevada law, against all expense, liability and loss (including, without limitation, attorneys' fees, judgments, fines, taxes, penalties, and amounts paid or to be paid in settlement) reasonably incurred or suffered by the Indemnitee in connection with any Proceeding; provided that such Indemnitee either is not liable pursuant to Nevada Revised Statutes Section 78.138 or acted in good faith and in a manner such Indemnitee reasonably believed to be in or not opposed to the best interests of the Registrant and, with respect to any Proceeding that is criminal in nature, had no reasonable cause to believe that his or her conduct was unlawful. The termination of any Proceeding by judgment, order, settlement, conviction or upon a plea of nolo contendere or its equivalent, does not, of itself, create a presumption that the Indemnitee is liable pursuant to Nevada Revised Statutes Section 78.138 or did not act in good faith and in a manner in which he or she reasonably believed to be in or not opposed to the best interests of the Registrant, or that, with respect to any criminal proceeding he or she had reasonable cause to believe that his or her conduct was unlawful. The Registrant shall not indemnify an Indemnitee for any claim, issue or matter as to which the Indemnitee has been adjudged by a court of competent jurisdiction, after exhaustion of all appeals therefrom, to be liable to the Registrant or for any amounts paid in settlement to the Registrant, unless and only to the extent that the court in which the Proceeding was brought or other court of competent jurisdiction determines upon application that in view of all the circumstances of the case, the Indemnitee is fairly and reasonably entitled to indemnity for such amounts as the court deems proper. Except as so ordered by a court and for advancement of expenses pursuant to this Section, indemnification may not be made to or on behalf of an Indemnitee if a final adjudication establishes that his or her acts or omissions involved intentional misconduct, fraud or a knowing violation of law and was material to the cause of action. Notwithstanding the foregoing, no director or officer may be indemnified for expenses incurred in defending any threatened, pending, or completed action, suit or proceeding (including without limitation, an action, suit or proceeding by or in the right of the Registrant), whether civil, criminal, administrative or investigative, that such director or officer incurred in his or her capacity as a stockholder.

The employment agreements the Registrant has entered into with certain of its officers provide that the Registrant will indemnify these individuals to the fullest extent permitted under Nevada law against liabilities that may arise by reason of their service to the Registrant, and cover these individuals under the Registrant's directors' and officers' liability insurance on the same basis as it covers its other officers and directors.

In addition, the Registrant has entered into indemnification agreements with each of its directors and officers. These agreements require the Registrant to indemnify these individuals to the fullest extent permitted under Nevada law against liabilities that may arise by reason of their service to the Registrant, and to advance expenses incurred as a result of any proceeding against them as to which they could be indemnified.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that, in the opinion of the Commission, such indemnification is against public policy and is, therefore, unenforceable.

**Item 7.** **Exemption from Registration Claimed.**

Not applicable.

A list of exhibits filed with this Registration Statement is set forth in the Exhibit Index hereto and is incorporated herein by reference.

**Item 9.** **Undertakings.**

(a) The
undersigned Registrant hereby undertakes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) To file, during any period
 in which offers or sales are being made, a post-effective amendment to this Registration Statement:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) To include any prospectus
 required by Section 10(a)(3) of the Securities Act;

(ii) To reflect in the prospectus
 any facts or events arising after the effective date of the Registration Statement (or the most recent post-effective amendment thereof)
 which, individually or in the aggregate, represent a fundamental change in the information set forth in the Registration Statement.
 Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities
 offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering
 range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes
 in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in Exhibit 107 (Filing
 Fee Table) to the effective Registration Statement; and

(iii) To include any material
 information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change
 to such information in the Registration Statement;

 

*provided, however*, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the Registration Statement is on Form S-8, and the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in the Registration Statement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) That, for the purpose of
 determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement
 relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial *bona fide* offering thereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) To remove from registration
 by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) The
 undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of
 the Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each
 filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Exchange Act), that is incorporated by
 reference in the Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein,
 and the offering of such securities at that time shall be deemed to be the initial *bona fide* offering thereof.

(c) Insofar
 as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons
 of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the
 Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In
 the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred
 or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding)
 is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will,
 unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction
 the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed
 by the final adjudication of such issue.

**SIGNATURES**

Pursuant to the requirements of the Securities Act, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-8 and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized in the City of Redmond, Oregon, on March 26, 2026

Re: *Registration Statement on Form S-8*

Ladies and Gentlemen:

You have requested our opinion with respect to certain matters in connection with the filing by Expion360 Inc., a Nevada corporation (the "***Company***"), of a Registration Statement on Form S-8 (as such may be amended or supplemented from time to time, the "***Registration Statement***") with the Securities and Exchange Commission on the date hereof under the Securities Act of 1933, as amended (the "***Securities Act***").

The Registration Statement covers the offer, issuance and sale of an aggregate of 492,487 shares (the "***Shares***") of the Company's common stock, par value $0.001 per share (the "***Common Stock***"), which includes (i) 489,086 shares of Common Stock reserved for issuance under the Expion360 Inc. 2021 Incentive Award Plan (the "***2021 Plan***") pursuant to the evergreen provision set forth in the 2021 Plan reflecting the automatic annual increase effective as of January 1, 2026, and (ii) 3,401 shares of Common Stock reserved for issuance under the 2021 Plan pursuant to the evergreen provision set forth in the 2021 Plan reflecting the automatic annual increase effective as of January 1, 2023.

In connection with this opinion, we have examined such documents and considered such questions of law as we have deemed necessary or appropriate. We have assumed the genuineness of all signatures, the authenticity of all documents submitted to us as originals, and the conformity to originals of all documents submitted to us as copies. As to certain factual matters, we have relied upon a certificate of an officer of the Company and have not independently verified such matters.

Subject to the foregoing, and the other matters set forth herein, it is our opinion that the Shares, when issued and sold in accordance with the terms of the 2021 Plan, and the related award agreements, will be validly issued, fully paid and non-assessable.

Our opinion is expressed only with respect to the General Corporation Law of the State of Nevada. We express no opinion to the extent that any other laws are applicable to the subject matter hereof, and express no opinion and provide no assurance as to compliance with any federal or state securities law, rule or regulation.

We consent to the use of this opinion as Exhibit 5.1 to the Registration Statement, and to the reference to our firm in the Registration Statement and any amendments or supplements thereto. In giving such consent, we do not admit that we are within the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations thereunder.

This opinion is intended solely for use in connection with the issuance and sale of the Shares pursuant to the Registration Statement and is not to be relied upon for any other purpose or delivered to or relied upon by any other person without our prior written consent. This opinion is rendered as of the date hereof and based solely on our understanding of facts in existence as of such date after the examination described in this opinion. We assume no obligation to advise you of any fact, circumstance, event or change in the law or the facts that may hereafter be brought to our attention whether or not such occurrence would affect or modify the opinions expressed herein.
