The Warrants, which were issued on September 4, 2026, have an exercise price of $3.30 per share (subject to adjustment), are exercisable at any time following issuance, and have a term of five years from the date of issuance. See “Prospectus Summary - Recent Developments – Loan and Warrant Financing” for additional information regarding the Warrants and the transaction pursuant to which the Warrants were issued.

The Selling Stockholders may sell the shares of our common stock offered by this prospectus from time to time on terms to be determined at the time of sale through ordinary brokerage transactions or through any other means described in this prospectus under the caption “Plan of Distribution.” The shares of common stock may be sold at fixed prices, at market prices prevailing at the time of sale, at prices related to prevailing market price or at negotiated prices.

We are not selling any shares of common stock under this prospectus and will not receive any proceeds from the sale by the Selling Stockholders of such shares. We are paying the cost of registering the shares of common stock covered by this prospectus as well as various related expenses. The Selling Stockholders are responsible for all selling commissions, transfer taxes and other costs related to the offer and sale of their shares.

Our common stock is listed on The Nasdaq Capital Market under the symbol “NEOV.” On October 1, 2026, the closing price of the common stock, as reported on Nasdaq, was $2.52 per share.

We are an “emerging growth company” as defined in Section 2(a) of the Securities Act and we have elected to comply with certain reduced public company reporting requirements.

Overview

We are a rapidly-growing U.S.-based energy technology company delivering scalable energy storage solutions. We are presently transitioning from being a storage manufacturer into an integrated energy solutions leader. Since our founding in 2018 solely as a manufacturer of high-performance energy storage systems for residential and small commercial applications, we have evolved into a more diversified storage technology company. Currently, our strategy is centered around building a multi-market energy solutions platform serving customer markets in the following three areas:

·	Residential	-	Our legacy energy storage business
·	Commercial & Industrial (“C&I”)	-	A logical extension from our legacy business
·	Utility-Scale	-	Our new energy storage initiative

Since April 2024, we have adopted a growth strategy which is designed to be focused around our customer base and structured to expand our market penetration, diversify revenue channels, and accelerate product development on a scalable basis. This strategy rests on three primary objectives: (i) expanding revenue through strategic sales channel development, (ii) broadening financing options through partnerships, and (iii) initiating development of next-generation storage solutions.

Recent Developments

Loan and Warrant Financing

On September 4, 2026 (the “Closing Date”), we entered into a Loan, Security and Guaranty Agreement (the “Loan Agreement”) with Horizon Technology Finance Corporation, a Delaware corporation (“Horizon”), as collateral agent and a lender, ROHO Capital Opportunity Fund LLC, a Delaware limited liability company (“ROHO”), as a lender, and Monroe Capital Management Advisors, LLC, a Delaware limited liability company (“Monroe Capital”), as administrative agent. Pursuant to the Loan Agreement, the lenders agreed to make term loans to us in an aggregate principal amount of $20,000,000 (the “Loans”), with a potential increase of up to an additional $10,000,000 subject to the conditions set forth in the Loan Agreement.

The Loans have a scheduled maturity date of March 3, 2028 and bear interest at a rate of 10.00% per annum. The Loans are subject to scheduled amortization payments, with the first amortization payment due on December 4, 2026 and subsequent payments due on the fourth day of each calendar month thereafter through the maturity date. The amortization amount for each payment date is equal to, in the aggregate, the greater of $1,250,000 or 7.5% of the “value traded” in our common stock for the previous month, subject to a cap of $2,000,000 per payment date. We may, at our option, prepay all or any portion of the outstanding Loans without premium or penalty. The Loans are secured by a first-priority security interest in substantially all of our assets and the assets of our subsidiaries, which serve as guarantors of our obligations under the Loan Agreement.

Description of the Warrants

In connection with the Loan Agreement, we issued to the lenders (the Selling Stockholders named herein) the Warrants to purchase an aggregate of 1,454,545 shares of our common stock. We also agreed to issue additional warrants to purchase up to 727,273 shares of common stock, on a pro rata basis, if the loan amounts are increased. The Warrants, which were issued on September 4, 2026, have an exercise price of $3.30 per share (subject to adjustment), are exercisable at any time following issuance, and have a term of five years from the date of issuance. The Selling Stockholders are prohibited from exercising any Warrants to the extent that such exercise would result in the number of shares of common stock beneficially owned by such Selling Stockholder and its affiliates exceeding 4.9% of the total number of shares of common stock outstanding immediately after giving effect to the exercise. In addition, the Warrants are subject to a “Cap Allocation Amount,” which limits the number of shares issuable upon exercise of each Warrant to a number of shares equal to such holder’s pro rata share of 19.99% of the shares of common stock outstanding on the issue date (as adjusted for stock splits, stock dividends and similar events), less any shares previously issued upon exercise of such Warrant. This cap applies unless and until we obtain stockholder approval in accordance with Nasdaq listing rules to permit the issuance of shares upon exercise of the Warrants in excess of the Cap Allocation Amount (the “Stockholder Approval”). The Warrants were issued in reliance upon the exemption from registration provided by Section 4(a)(2) of the Securities Act of 1933, as amended.

We are required under the Warrants to take all necessary action to obtain the Stockholder Approval, and may not engage in any dilutive issuance that would cause a Warrant to be exercisable for shares in excess of the Cap Allocation Amount without first obtaining such approval. In the event of certain fundamental transactions, the holder of the Warrants will have the right to receive the Black Scholes Value (as defined in the Warrants) of its Warrants calculated pursuant to a formula set forth in the Warrants, payable either in cash or in the same type or form of consideration that is being offered and being paid to the holders of common stock.

If, while the Warrants are outstanding, we issue or sell, or are deemed to have issued or sold, any common stock and/or common stock equivalents other than in connection with certain exempt issuances, at a purchase price per share less than the exercise price of the Warrants in effect immediately prior to such issuance or sale or deemed issuance or sale, then immediately after such issuance or sale or deemed issuance or sale, the exercise price of the Warrants then in effect will be reduced based on a weighted average dilution formula and the number of shares underlying the Warrant will be proportionately increased, subject to the Cap Allocation Amount described above.

This prospectus relates to the resale by the Selling Stockholders of the shares of common stock issuable upon exercise of the Warrants.

Registration Rights Agreement

In connection with the Loan Agreement, we also entered into a Registration Rights Agreement (the “Registration Rights Agreement”) with the Selling Stockholders, pursuant to which we agreed to file a registration statement with the SEC to register the resale of the shares of common stock issuable upon exercise of the Warrants. This prospectus forms part of such registration statement.

Corporate Information

Our corporate headquarters are located at 12195 Dearborn Place, Poway, California 92064. Our telephone number is (800) 364-5464. Our principal website address is www.neovolta.com. Information contained in, or accessible through, our website is not a part of this prospectus and the inclusion of our website address herein is an inactive textual reference only.

Implications of Being a Smaller Reporting Company

We are a “smaller reporting company,” meaning that the market value of our common stock held by non-affiliates is less than $250.0 million measured on the last business day of our second fiscal quarter or our annual revenue is less than $100.0 million during the most recently completed fiscal year and the market value of our common stock held by non-affiliates is less than $700.0 million measured on the last business day of our second fiscal quarter. Accordingly, we may provide less public disclosure than larger public companies, including the inclusion of only two years of audited financial statements and only two years of management’s discussion and analysis of financial condition and results of operations disclosure. As a result, the information that we provide to our stockholders may be different than what you might receive from other public reporting companies in which you hold equity interests.

Implications of Being an Emerging Growth Company

As a company with less than $1.235 billion in revenues during our last fiscal year, we qualify as an emerging growth company as defined in the Jumpstart Our Business Startups Act (“JOBS Act”) enacted in 2012. As an emerging growth company, we expect to take advantage of reduced reporting requirements that are otherwise applicable to public companies. These provisions include, but are not limited to:

being permitted to present only two years of audited financial statements, in addition to any required unaudited interim financial statements, with correspondingly reduced “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”;

not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, as amended (“Sarbanes-Oxley Act”);

reduced disclosure obligations regarding executive compensation in our periodic reports, proxy statements and registration statements; and

exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved.

We may use these provisions until the last day of our fiscal year following the fifth anniversary of the completion of our initial public offering. However, if certain events occur prior to the end of such five-year period, including if we become a “large accelerated filer,” our annual gross revenues exceed $1.235 billion or we issue more than $1.0 billion of non-convertible debt in any three-year period, we will cease to be an emerging growth company prior to the end of such five-year period. The JOBS Act provides that an emerging growth company can take advantage of an extended transition period for complying with new or revised accounting standards. As an emerging growth company, we intend to take advantage of an extended transition period for complying with new or revised accounting standards as permitted by the JOBS Act.

To the extent that we continue to qualify as a “smaller reporting company,” as such term is defined in Rule 12b-2 under the Securities Exchange Act of 1934, after we cease to qualify as an emerging growth company, certain of the exemptions available to us as an emerging growth company may continue to be available to us as a smaller reporting company, including: (i) not being required to comply with the auditor attestation requirements of Section 404(b) of the Sarbanes-Oxley Act; (ii) scaled executive compensation disclosures; and (iii) the requirement to provide only two years of audited financial statements, instead of three years.

Risks Affecting Our Company

In evaluating an investment in our securities, you should carefully read this prospectus and especially consider the factors incorporated by reference in the section titled “Risk Factors” commencing on page 6 of this prospectus and our Annual Report on Form 10-K for the year ended June 30, 2026, incorporated by reference herein.

THE OFFERING

Shares of common stock outstanding as of September 30, 2026:		59,013,247

Use of proceeds:		We will not receive any of the proceeds from any sale of shares of common stock by the Selling Stockholders. If all of the Warrants are exercised for cash, we will receive approximately $4.8 million in gross proceeds.

Risk factors:		An investment in our securities involves substantial risk. You should read carefully the “Risk Factors” section on page 6 of this prospectus, and under similar headings in the other documents incorporated by reference into this prospectus. Additional risks and uncertainties not presently known to us or that we currently deem to be immaterial may also impair our business and operations.

Nasdaq Capital Market symbol:		Our common stock is listed on The Nasdaq Capital Market under the symbol “NEOV”.

The number of shares of common stock outstanding is based on 59,013,247 shares outstanding as of September 30, 2026, and excludes:

1,454,545 shares of common stock issuable upon exercise of the Warrants (as defined herein);

1,081,150 shares of common stock underlying outstanding warrants at a weighted average exercise price of $4.00 per share (excluding the Warrants);

2,385,697 shares of common stock underlying outstanding options with a weighted average exercise price of $3.54 per share;

2,227,254 shares available for future grants under the Company’s Stock Plan.

Except as otherwise indicated, the information in this prospectus assumes no exercise of options or exercise of warrants.

Before making an investment decision, in addition to the risks set forth below, you should consider the “Risk Factors” included under Item 1A. of our most recent Annual Report on Form 10-K, and in our Quarterly Reports on Form 10-Q, and in our updates to those Risk Factors which are incorporated by reference in this prospectus, as updated by our future filings with the SEC. The market or trading price of our common stock could decline due to any of these risks. In addition, please read “Cautionary Note Regarding Forward-Looking Statements” in this prospectus, where we describe additional uncertainties associated with our business and the forward-looking statements included or incorporated by reference in this prospectus. Please note that additional risks not currently known to us or that we currently deem immaterial may also impair our business and operations.

The number of shares of common stock issuable upon exercise of the Warrants being registered for resale is significant in relation to the number of our outstanding shares of common stock.

We have filed a registration statement of which this prospectus is a part to register the shares issuable upon exercise of the Warrants offered hereunder for sale into the public market by the Selling Stockholders. These shares, if issued and sold, would represent a noteworthy number of shares of our common stock relative to our outstanding shares. The sale of all or a substantial portion of these shares in the market within a short period of time could adversely affect the market price of our common stock during the period the registration statement remains effective and could also adversely affect our ability to raise equity capital.

Some of the information in this prospectus, and the documents we incorporate by reference, contain forward-looking statements within the meaning of the federal securities laws. You should not rely on forward-looking statements in this prospectus, and the documents we incorporate by reference. Forward-looking statements typically are identified by use of terms such as “anticipate,” “believe,” “plan,” “expect,” “future,” “intend,” “may,” “will,” “should,” “estimate,” “predict,” “potential,” “continue,” and similar words, although some forward-looking statements are expressed differently. This prospectus, and the documents we incorporate by reference, may also contain forward-looking statements attributed to third parties relating to their estimates regarding the markets we may enter in the future. All forward-looking statements address matters that involve risk and uncertainties, and there are many important risks, uncertainties and other factors that could cause our actual results to differ materially from the forward-looking statements contained in this prospectus, and the documents we incorporate by reference.

You should also carefully consider the statements under “Risk Factors” and other sections of this prospectus, which address additional facts that could cause our actual results to differ from those set forth in the forward-looking statements. We caution investors not to place significant reliance on the forward-looking statements contained in this prospectus, and the documents we incorporate by reference. We undertake no obligation to publicly update or review any forward-looking statements, whether as a result of new information, future developments or otherwise.

All shares of our common stock offered by this prospectus are being registered for the account of the Selling Stockholders identified herein. We will not receive any of the proceeds from the sale of these shares. To the extent that the Warrants are exercised for cash, we will receive the exercise price of the Warrants, which would be up to approximately $4.8 million in aggregate gross proceeds if the Warrants were exercised in full for cash at the current exercise price of $3.30 per share. We intend to use any proceeds received from the exercise of the Warrants for general corporate purposes.

We are registering the shares of common stock issuable upon exercise of the Warrants in order to permit the Selling Stockholders to offer the shares for resale from time to time.

Except for the Loan Agreement described above under “Prospectus Summary – Recent Developments - Loan and Warrant Financing” and the Registration Rights Agreement described therein, as well as the Selling Stockholders’ ownership of shares of our common stock issuable upon exercise of the Warrants, the Selling Stockholders have not had any material relationship with us or any of our affiliates within the past three years.

The table below lists the Selling Stockholders and other information regarding the beneficial ownership of the shares of common stock by the Selling Stockholders. The second column lists the number of shares of common stock beneficially owned by each Selling Stockholder, based on its ownership of the Warrants, as of September 30, 2026, assuming full exercise of the Warrants, without regard to any limitations on exercise and assuming no adjustments to the number of shares exercisable upon exercise of the Warrants. The third column lists the shares of common stock being offered by this prospectus by each Selling Stockholder. The Warrants are subject to a 4.9% beneficial ownership limitation and a Cap Allocation Amount. See “Prospectus Summary – Recent Developments – Loan and Warrant Financing” for a description of the Warrants.

In accordance with the terms of the Registration Rights Agreement with the Selling Stockholders, this prospectus covers the resale of up to 1,454,545 shares of common stock issuable upon exercise of the Warrants described above. The fourth column assumes no adjustments to the number of shares exercisable upon exercise of the Warrants and the sale of all of the shares offered by the Selling Stockholders pursuant to this prospectus.

Under the terms of the Warrants, the Warrants may not be exercised to the extent that, after giving effect to such exercise, the applicable Selling Stockholder (together with its affiliates and any other persons acting as a group together with such Selling Stockholder or any of its affiliates) would beneficially own shares in excess of 4.9% of the total number of shares of common stock outstanding immediately after giving effect to the exercise, and the Warrants are further subject to the Cap Allocation Amount described above. The number of shares in the second and fourth columns do not reflect these limitations. The Selling Stockholders may sell all, some or none of their shares in this offering. See “Plan of Distribution.”

The Selling Stockholders of the securities and any of their pledgees, assignees and successors-in-interest may, from time to time, sell any or all of their securities covered hereby on The Nasdaq Capital Market or any other stock exchange, market or trading facility on which the securities are traded or in private transactions. These sales may be at fixed or negotiated prices. The Selling Stockholders may use any one or more of the following methods when selling securities:

The Selling Stockholders may also sell securities under Rule 144 or any other exemption from registration under the Securities Act, if available, rather than under this prospectus.

The Selling Stockholders may, from time to time, pledge or grant a security interest in some or all of the shares of common stock owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the shares of common stock, from time to time, under this prospectus, or under an amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act, by amending the list of Selling Stockholders to include the pledgee, transferee or other successors in interest as Selling Stockholders under this prospectus. The Selling Stockholders also may transfer the shares of common stock in other circumstances, in which case the transferees, pledgees or other successors in interest will be the Selling Stockholders for purposes of this prospectus.

Broker-dealers engaged by the Selling Stockholders may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the Selling Stockholders (or, if any broker-dealer acts as agent for the purchaser of securities, from the purchaser) in amounts to be negotiated, but, except as set forth in a supplement to this prospectus, in the case of an agency transaction not in excess of a customary brokerage commission in compliance with Financial Industry Regulatory Authority (“FINRA”) Rule 2121; and in the case of a principal transaction a markup or markdown in compliance with FINRA Rule 2121.

In connection with the sale of the securities or interests therein, the Selling Stockholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the securities in the course of hedging the positions they assume. The Selling Stockholders may also sell securities short and deliver these securities to close out their short positions, or loan or pledge the securities to broker-dealers that in turn may sell these securities, and if such short sale shall take place after the date that this Registration Statement is declared effective by the Commission, the Selling Stockholders may deliver securities covered by this prospectus. The Selling Stockholders may also enter into option or other transactions with broker-dealers or other financial institutions or create one or more derivative securities which require the delivery to such broker-dealer or other financial institution of securities offered by this prospectus, which securities such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

Any broker-dealers or agents that are involved in selling the securities may be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the securities purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act.

The Company is required to pay certain fees and expenses incurred by the Company incident to the registration of the securities. The Company has agreed to indemnify the Selling Stockholders against certain losses, claims, damages and liabilities, including liabilities under the Securities Act.

We agreed to keep this prospectus effective until the earlier of (i) the date on which the securities may be resold by the Selling Stockholders without registration and without regard to any volume or manner-of-sale limitations by reason of Rule 144, without the requirement for the Company to be in compliance with the current public information under Rule 144 under the Securities Act or any other rule of similar effect or (ii) all of the securities have been sold pursuant to this prospectus or Rule 144 under the Securities Act or any other rule of similar effect. The resale securities will be sold only through registered or licensed brokers or dealers if required under applicable state securities laws. In addition, in certain states, the resale securities covered hereby may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with.

Under applicable rules and regulations under the Exchange Act, any person engaged in the distribution of the resale securities may not simultaneously engage in market making activities with respect to the shares of common stock for the applicable restricted period, as defined in Regulation M, prior to the commencement of the distribution. In addition, the Selling Stockholders will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including Regulation M, which may limit the timing of purchases and sales of the shares of common stock by the Selling Stockholders or any other person. We will make copies of this prospectus available to the Selling Stockholders and have informed them of the need to deliver a copy of this prospectus to each purchaser at or prior to the time of the sale (including by compliance with Rule 172 under the Securities Act).

A Selling Stockholder that is an entity may elect to make an in-kind distribution of shares of common stock covered by this prospectus to its members, partners or stockholders pursuant to the registration statement of which this prospectus is a part by delivering a prospectus. To the extent that such members, partners or stockholders are not affiliates of ours, such members, partners or stockholders would thereby receive freely tradable shares of common stock pursuant to the distribution through a registration statement.

The financial statements of NeoVolta, Inc. incorporated in this prospectus by reference to the Annual Report on Form 10-K for the year ended June 30, 2026, have been so incorporated in reliance on the report of MaloneBailey, LLP, an independent registered public accounting firm, given on the authority of said firm as experts in auditing and accounting.

We have filed with the SEC a registration statement on Form S-3 under the Securities Act with respect to the securities offered by this prospectus. This prospectus, which is part of the registration statement, does not contain all of the information included in the registration statement and the exhibits.

The following table sets forth the estimated costs and expenses to be incurred in connection with the issuance and distribution of the securities of NeoVolta, Inc., which are registered under this Registration Statement on Form S-3, other than underwriting discounts and commissions. All expenses will be borne by NeoVolta, Inc. All amounts are estimates except the Securities and Exchange Commission registration fee.

Section 78.138 of the Nevada Revised Statute provides that a director or officer is not individually liable to the corporation or its stockholders or creditors for any damages as a result of any act or failure to act in his capacity as a director or officer unless it is proven that (1) his act or failure to act constituted a breach of his fiduciary duties as a director or officer and (2) his breach of those duties involved intentional misconduct, fraud or a knowing violation of law.

This provision is intended to afford directors and officers protection against and to limit their potential liability for monetary damages resulting from suits alleging a breach of the duty of care by a director or officer. As a consequence of this provision, stockholders of our company will be unable to recover monetary damages against directors or officers for action taken by them that may constitute negligence or gross negligence in performance of their duties unless such conduct falls within one of the foregoing exceptions. The provision, however, does not alter the applicable standards governing a director’s or officer’s fiduciary duty and does not eliminate or limit the right of our company or any stockholder to obtain an injunction or any other type of non-monetary relief in the event of a breach of fiduciary duty.

The Registrant’s Amended and Restated Articles of Incorporation and Second Amended and Restated Bylaws provide for indemnification of directors, officers, employees or agents of the Registrant to the fullest extent permitted by Nevada law (as amended from time to time). Section 78.7502 of the Nevada Revised Statute provides that such indemnification may only be provided if the person acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to, the best interest of the Registrant and, with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful.

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(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 Securities and Exchange Commission (the “Commission”), pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in 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), (a)(1)(ii) and (a)(1)(iii) do not apply if 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 Securities Exchange Act of 1934 (the “Exchange Act”), that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

(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.

(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.

(4) That, for the purpose of determining liability under the Securities Act to any purchaser:

(i) Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(ii) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5) or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii) or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which the prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

(iii) If the registrant is subject to Rule 430C, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.

(5) 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 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.

(6) 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 Securities and Exchange Commission such indemnification is against public policy as expressed in the 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 Act and will be governed by the final adjudication of such issue.

Pursuant to the requirements of the Securities Act of 1933, the registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-3 and has duly caused this registration statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the city of Poway, California, on October 2, 2026.
