ABOUT THIS PROSPECTUS

This prospectus is part of a registration statement that we filed with the U.S. Securities and Exchange Commission, or the SEC, using a "shelf" registration process. Under the shelf registration process, we may, from time to time, offer and sell in one or more offerings, up to a total dollar amount of $250,000,000 of the securities described in this prospectus.

This prospectus provides you with a general description of the securities we may offer. Each time we offer to sell securities pursuant to this prospectus, we will provide a prospectus supplement that will contain specific information about that offering and the specific terms of the securities offered. We may also authorize one or more free writing prospectuses to be provided to you that may contain material information relating to these offerings. The prospectus supplement may include additional risk factors or other special considerations applicable to the securities being offered. The prospectus supplement or free writing prospectus may also add, update or change information contained in this prospectus. If there is any inconsistency between the information contained or incorporated by reference in this prospectus, on the one hand, and any information contained or incorporated by reference in any applicable prospectus supplement or free writing prospectus, on the other hand, you should rely on the information contained or incorporated by reference in the applicable prospectus supplement or free writing prospectus. You should read both this prospectus and any prospectus supplement and the documents incorporated by reference herein and therein carefully before making your investment decision. You should also read the documents we have referred you to under the headings "Where You Can Find More Information" and "Incorporation by Reference."

We have not authorized any other person to provide you with any information or to make any representations other than those contained in this prospectus, any applicable prospectus supplement or any free writing prospectuses prepared by or on behalf of us or to which we have referred you. We take no responsibility for, and can provide no assurance as to the reliability of, any other information that others may give you. We will not make an offer to sell these securities in any jurisdiction where the offer or sale is not permitted. You should assume that the information appearing in this prospectus and the applicable prospectus supplement to this prospectus is accurate only as of the date on its respective cover, that the information appearing in any applicable free writing prospectus is accurate only as of the date of that free writing prospectus, and that any information incorporated by reference is accurate only as of the date of the document incorporated by reference, unless we indicate otherwise. Our business, financial condition, results of operations and prospects may have changed since those dates. This prospectus incorporates by reference, and any prospectus supplement or free writing prospectus may contain and incorporate by reference, market data and industry statistics and forecasts that are based on independent industry publications and other publicly available information. Although we believe these sources are reliable, we do not guarantee the accuracy or completeness of this information and we have not independently verified this information. In addition, the market and industry data and forecasts that may be included or incorporated by reference in this prospectus, any prospectus supplement or any applicable free writing prospectus may involve estimates, assumptions and other risks and uncertainties and are subject to change based on various factors, including those discussed under the heading "Risk Factors" contained in this prospectus, the applicable prospectus supplement and any applicable free writing prospectus, and under similar headings in other documents that are incorporated by reference into this prospectus. Accordingly, investors should not place undue reliance on this information.

When we refer to "American Battery Technology Company," "ABAT," "we," "our," "us" and the "Company" in this prospectus, we mean American Battery Technology Company and its consolidated subsidiaries, unless otherwise specified. When we refer to "you," we mean the potential holders of the applicable series of securities.

INCORPORATION BY REFERENCE

The SEC's rules allow us to "incorporate by reference" information into this prospectus, which means that we can disclose important information to you by referring you to another document filed separately with the SEC.

We are not, however, incorporating by reference any documents or portions thereof, whether specifically listed below or filed in the future, that are not deemed "filed" with the SEC, including any information furnished pursuant to Item 2.02 or 7.01 of Form 8-K or related exhibits furnished pursuant to Item 9.01 of Form 8-K.

THE COMPANY

This summary description about us and our business highlights selected information contained elsewhere in this prospectus supplement or the accompanying prospectus, or incorporated by reference in this prospectus supplement or the accompanying prospectus. This summary does not contain all of the information that you should consider before buying securities in this offering. You should carefully read this entire prospectus supplement and the accompanying prospectus, including each of the documents incorporated herein or therein by reference, before making an investment decision.

Overview

American Battery Technology Company (the "Company", "ABTC", "we" and "us") is an integrated critical minerals manufacturing company that is working to increase the domestic U.S. production of critical minerals, such as lithium, nickel, cobalt, manganese, copper, aluminum, and graphite through its exploration of new primary resources of critical minerals, the development and commercialization of new technologies for the extraction of these critical minerals from primary resources, and the commercialization of an internally developed integrated process for the recycling of lithium-ion batteries. Through this three-pronged approach the Company is working to both increase the domestic production of these critical minerals and to ensure that as these materials reach their end of life, the constituent elemental critical minerals are returned to the domestic manufacturing supply chain in a closed-loop fashion.

ABTC has won several competitive funding opportunities from the US Government, and has signed strategic partnership and supply agreements with some of the largest corporations in the world.

The Company's corporate headquarters are in Reno, Nevada, and its critical mineral exploration office is located in Tonopah, Nevada. The Company's critical mineral recycling factory is in McCarran, Nevada.

Background

The Company was incorporated as Oroplata Resources, Inc. under the laws of the State of Nevada on October 6, 2011, for the purpose of acquiring rights to mineral properties with the eventual objective of being a producing mineral company. On August 8, 2016, the Company formed Lithortech Resources Inc. as a wholly owned subsidiary to serve as its operating subsidiary for lithium resource exploration and mine development. On June 29, 2018, the Company changed the name of Lithortech Resources to LithiumOre Corp. ("LithiumOre"). On May 3, 2019, the Company changed its name to American Battery Metals Corporation. On August 12, 2021, the Company further changed its name to American Battery Technology Company, which better aligns with the Company's current business activities and future objectives.

Smaller Reporting Company

We are a "smaller reporting company" as defined by Rule 12b-2 of the Exchange Act. We may take advantage of certain of the scaled disclosures available to smaller reporting companies and will be able to take advantage of these scaled disclosures for so long as 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. For example, as a smaller reporting company we may choose to present only the two most recent fiscal years of audited financial statements in our Annual Report on Form 10-K and we have reduced disclosure obligations regarding executive compensation.

Corporate Information

Our mailing address and telephone number of our principal executive offices are:

American Battery Technology Company

100 Washington Street, Suite 100

Reno, Nevada 89503

Tel: (775) 473-4744

Our corporate website address is americanbatterytechnology.com. Information contained on or accessible through our website is not a part of this prospectus, and the inclusion of our website address in this prospectus is an inactive textual reference only.

RISK FACTORS

Investment in any securities offered pursuant to this prospectus and the applicable prospectus supplement involves risks. Before deciding whether to invest in our securities, you should carefully consider the risk factors incorporated by reference to our most recent Annual Report on Form 10-K and any subsequent Quarterly Reports on Form 10-Q or Current Reports on Form 8-K, and all other information contained in or incorporated by reference into this prospectus, as updated by our subsequent filings under the Exchange Act, and the risk factors and other information contained in the applicable prospectus supplement and any applicable free writing prospectus. The occurrence of any of these risks might cause you to lose all or part of your investment in the offered securities. There may be other unknown or unpredictable economic, business, competitive, regulatory or other factors that could have material adverse effects on our future results. Past financial performance may not be a reliable indicator of future performance, and historical trends should not be used to anticipate results or trends in future periods. If any of these risks actually occurs, our business, financial condition, results of operations or cash flow could be seriously harmed. This could cause the trading price of our securities to decline, resulting in a loss of all or part of your investment. Please also carefully read the section entitled "Cautionary Note Regarding Forward-Looking Statements" included herein and the section entitled "Cautionary Note Regarding Forward-Looking Statements" included in our most recent Annual Report on Form 10-K and any subsequent Quarterly Reports on Form 10-Q or Current Reports on Form 8-K.

USE OF PROCEEDS

Unless otherwise indicated in a prospectus supplement relating to a specific offering, we intend to use the net proceeds from the sale of securities by us under this prospectus for general corporate purposes, which may include working capital, capital expenditures, operational purposes and potential acquisitions.

The intended application of proceeds from the sale of any particular offering of securities using this prospectus will be described in the accompanying prospectus supplement relating to such offering. The precise amount and timing of the application of these proceeds will depend on our funding requirements and the availability and costs of other funds.

DIVIDEND POLICY

We have never declared or paid any cash dividends on our Common Stock. We currently intend to retain all available funds and any future earnings to support our operations and finance the growth and development of our business. We do not intend to pay cash dividends on our Common Stock for the foreseeable future. Any future determination related to dividend policy will be made at the discretion of our Board of Directors.

The holders of the Series B and Series C Preferred Stock are entitled to receive an 8% per annum dividend on their stated value which can be paid in cash or Common Stock at the discretion of the Company (see descriptions of the Preferred Stock below). As of September 11, 2026, there were no shares of Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock, or Series D Preferred Stock issued and outstanding.

The current and future holders of our Common Stock are entitled to receive dividends pro rata based on the number of shares held, when and if declared by our Board of Directors, from funds legally available for that purpose. Nevada Revised Statutes prohibits us from declaring dividends where, after giving effect to the distribution of the dividend, we would not be able to pay our debts as they become due in the ordinary course of business, or our total assets would be less than the sum of our total liabilities.

Our Articles of Incorporation and Bylaws do not contain provisions restricting our ability to pay dividends of our Common Stock.

Description of CAPITAL STOCK

The following description of our capital stock is not complete and may not contain all the information you should consider before investing in our capital stock. This description is summarized from, and qualified in its entirety by reference to, our Articles of Incorporation and Bylaws which have been publicly filed with the SEC. See "Where You Can Find More Information" and "Incorporation by Reference."

The Series D Preferred Stock may not be transferred at any time prior to stockholder approval of the Increase in Authorized Common Stock without the prior written consent of the Board of Directors.

Anti-Takeover Effects of Nevada Law and Our Charter Documents

Certain provisions of Nevada law and our Articles of Incorporation and Bylaws could make more difficult the acquisition of us by means of a tender offer or otherwise, and the removal of incumbent officers and directors. These provisions are expected to discourage certain types of coercive takeover practices and inadequate takeover bids and to encourage persons seeking to acquire control of us.

Nevada Revised Statutes (as amended, the "NRS")

Business Combinations

The "business combination" provisions of Sections 78.411 to 78.444, inclusive, of the Nevada Revised Statutes, or NRS, generally prohibit a Nevada corporation with at least 200 stockholders from engaging in various "combination" transactions with any interested stockholder for a period of two years after the date of the transaction in which the person became an interested stockholder, unless the transaction is approved by the board of directors prior to the date the interested stockholder obtained such status or the combination is approved by the board of directors and thereafter is approved at a meeting of the stockholders by the affirmative vote of stockholders representing at least 60% of the outstanding voting power held by disinterested stockholders, and extends beyond the expiration of the two-year period, unless:

	●	the combination was approved by the board of directors prior to the person becoming an interested stockholder or the transaction by which the person first became an interested stockholder was approved by the board of directors before the person became an interested stockholder or the combination is later approved by a majority of the voting power held by disinterested stockholders; or
	●	if the consideration to be paid by the interested stockholder is at least equal to the highest of: (a) the highest price per share paid by the interested stockholder within the two years immediately preceding the date of the announcement of the combination or in the transaction in which it became an interested stockholder, whichever is higher, (b) the market value per share of common stock on the date of announcement of the combination and the date the interested stockholder acquired the shares, whichever is higher, or (c) for holders of preferred stock, the highest liquidation value of the preferred stock, if it is higher.

A "combination" is generally defined to include mergers or consolidations or any sale, lease exchange, mortgage, pledge, transfer, or other disposition, in one transaction or a series of transactions, with an "interested stockholder" having: (a) an aggregate market value equal to 5% or more of the aggregate market value of the assets of the corporation, (b) an aggregate market value equal to 5% or more of the aggregate market value of all outstanding shares of the corporation, (c) 10% or more of the earning power or net income of the corporation, and (d) certain other transactions with an interested stockholder or an affiliate or associate of an interested stockholder.

In general, an "interested stockholder" is a person who, together with affiliates and associates, owns (or within two years, did own) 10% or more of a corporation's voting stock. The statute could prohibit or delay mergers or other takeover or change in control attempts and, accordingly, may discourage attempts to acquire our Company even though such a transaction may offer our stockholders the opportunity to sell their stock at a price above the prevailing market price. The Articles of Incorporation expressly elect not to be governed by these provisions of the NRS. Accordingly, the business combination statutes will not be applicable to us unless our Articles of Incorporation are amended in accordance with applicable law and the Articles of Incorporation to remove our election to opt out of the application of the statutes.

Control Share Acquisitions

The "control share" provisions of Sections 78.378 to 78.3793, inclusive, of the NRS apply to "issuing corporations" that are Nevada corporations with at least 200 stockholders, including at least 100 stockholders of record who are Nevada residents, and that conduct business directly or indirectly in Nevada. The control share statute prohibits an acquirer, under certain circumstances, from voting its shares of a target corporation's stock after crossing certain ownership threshold percentages, unless the acquirer obtains approval of the target corporation's disinterested stockholders. The statute specifies three thresholds: one-fifth or more but less than one-third, one-third but less than a majority, and a majority or more, of the outstanding voting power. Generally, once an acquirer crosses one of the above thresholds, those shares in an offer or acquisition and acquired within 90 days thereof become "control shares" and such control shares are deprived of the right to vote until disinterested stockholders restore the right. These provisions also provide that if control shares are accorded full voting rights and the acquiring person has acquired a majority or more of all voting power, all other stockholders who do not vote in favor of authorizing voting rights to the control shares are entitled to demand payment for the fair value of their shares in accordance with statutory procedures established for dissenters' rights.

The effect of the Nevada control share statutes is that the acquiring person, and those acting in association with the acquiring person, will obtain only such voting rights in the control shares as are conferred by a resolution of the stockholders at an annual or special meeting. The Nevada control share law, if applicable, could have the effect of discouraging takeovers of our Company. A corporation may elect to not be governed by, or "opt out" of, the control share provisions by making an election in its articles of incorporation or bylaws, provided that the opt-out election must be in place on the 10th day following the date an acquiring person has acquired a controlling interest, that is, crossing any of the three thresholds described above. The Articles of Incorporation expressly elect not to be governed by these provisions of the NRS. Accordingly, the control share statutes will not be applicable to us unless our Articles of Incorporation are amended in accordance with applicable law and the Articles of Incorporation to remove our election to opt out of the application of the statutes.

Articles of Incorporation and Bylaws

The Company's Articles of Incorporation and Bylaws include anti-takeover provisions that:

	●	authorize the Board of Directors, without further action by the stockholders, to issue shares of Preferred Stock in one or more series, and with respect to each series, to fix the number of shares constituting that series, and establish the rights and terms of that series;
	●	establish advance notice procedures for stockholders to submit nominations of candidates for election to the Board of Directors to be brought before a stockholders meeting;
	●	allow the Company's directors to establish the size of the Board of Directors and fill vacancies on the Board created by an increase in the number of directors (subject to the rights of the holders of any series of Preferred Stock to elect additional directors under specified circumstances);
	●	require the affirmative vote of the holders of at least two-thirds (2/3) of the voting power of all of the then-outstanding shares of capital stock of the Company entitled to vote generally in the election of directors in order to remove a director or the entire Board of Directors for cause;
	●	do not provide stockholders cumulative voting rights with respect to director elections; and
	●	provide that the Company's Bylaws may be amended by the Board of Directors without stockholder approval.

Provisions of the Company's Articles of Incorporation and Bylaws may delay or discourage transactions involving an actual or potential change in the Company's control or change in the Company's Board of Directors or management, including transactions in which stockholders might otherwise receive a premium for their shares or transactions that the Company's stockholders might otherwise deem to be in their best interests. Therefore, these provisions could adversely affect the price of our common stock.

Authorized and Unissued Shares

The Company's authorized and unissued shares of Common Stock are available for future issuance without stockholder approval except as may otherwise be required by applicable stock exchange rules or Nevada law. The Company may issue additional shares for a variety of purposes, including future offerings to raise additional capital, to fund acquisitions and as employee and consultant compensation. The existence of authorized but unissued shares of Common Stock could render more difficult, or discourage an attempt, to obtain control of the Company by means of a proxy contest, tender offer, merger or otherwise.

The issuance of shares of Preferred Stock by the Company could have certain anti-takeover effects under certain circumstances, and could enable the Board of Directors to render more difficult or discourage an attempt to obtain control of the Company by means of a merger, tender offer, or other business combination transaction directed at the Company by, among other things, placing shares of Preferred Stock with investors who might align themselves with the Board of Directors.

Transfer Agent

The transfer agent for our Common Stock is Securities Transfer Corporation at 2901 N. Dallas Parkway, Suite 380, Plano, TX 75093. The transfer agent's telephone number is (469) 633-0101.

DESCRIPTION OF WARRANTS

The following description, together with the additional information we may include in any applicable prospectus supplements, summarizes the material terms and provisions of the warrants that we may offer under this prospectus. While the terms summarized below will apply generally to any warrants that we may offer, we will describe the particular terms of any series of warrants in more detail in the applicable prospectus supplement. If we indicate in the prospectus supplement, the terms of any warrants offered under that prospectus supplement may differ from the terms described below. Specific warrant agreements will contain additional important terms and provisions and will be incorporated by reference as an exhibit to the registration statement of which this prospectus forms a part.

We may issue, together with any other securities being offered or separately, warrants entitling the holder to purchase from or sell to us, or to receive from us the cash value of the right to purchase or sell, Common Stock, Preferred Stock, or units. We and a warrant agent will enter into a warrant agreement pursuant to which the warrants will be issued. The warrant agent will act solely as our agent in connection with the warrants and will not assume any obligation or relationship of agency or trust for or with any holders or beneficial owners of warrants. We will file a copy of the forms of warrants and the warrant agreement with the SEC at or before the time of the offering of the applicable series of warrants.

In the event that we issue warrants, we will distribute a prospectus supplement with regard to each issue of warrants. Each prospectus supplement will describe, as to the warrants to which it relates:

	●	the securities which may be purchased by exercising the warrants (which may be Common Stock, Preferred Stock, or units consisting of two or more of those types of securities);
	●	the exercise price of the warrants (which may be wholly or partly payable in cash or wholly or partly payable with other types of consideration);
	●	the period during which the warrants may be exercised;
	●	any provision adjusting the securities which may be purchased on exercise of the warrants and the exercise price of the warrants in order to prevent dilution or otherwise;
	●	the place or places where warrants can be presented for exercise or for registration of transfer or exchange; and
	●	any other material terms of the warrants.

Exercise of Warrants

Warrants may be exercised as described in the applicable prospectus supplement. Until a holder exercises the warrants to purchase any securities underlying the warrants, the holder will not have any rights as a holder of the underlying securities by virtue of ownership of warrants. Warrants may be exercised at any time up to the close of business on the expiration date shown in the applicable prospectus supplement, unless otherwise specified in such prospectus supplement. Warrants may be exercised as described in the applicable prospectus supplement.

DESCRIPTION OF UNITS

The following description, together with the additional information we may include in any applicable prospectus supplements, summarizes the material terms and provisions of the units that we may offer under this prospectus. While the terms summarized below will apply generally to any units that we may offer, we will describe the particular terms of any series of units in more detail in the applicable prospectus supplement. If we indicate in the prospectus supplement, the terms of any units offered under that prospectus supplement may differ from the terms described below. Specific unit agreements will contain additional important terms and provisions and will be incorporated by reference as an exhibit to the registration statement of which this prospectus forms a part.

We may issue units composed of one or more of the other securities described in this prospectus in any combination. Each unit will be issued so that the holder of the unit is also the holder of each security included in the unit. If we issue units, the prospectus supplement relating to the units will contain the information described above with regard to each of the securities that is a component of the units. In addition, each prospectus supplement relating to units will:

	●	state how long, if at all, the securities that are components of the units must be traded in units, and when they can be traded separately;
	●	state whether we will apply to have the units traded on a securities exchange or securities quotation system; and
	●	describe how, for U.S. federal income tax purposes, the purchase price paid for the units is to be allocated among the component securities.

The provisions described in this section, as well as those described under "Description of Our Capital Stock" and "Description of Warrants" will apply to each unit, as applicable, and to any Common Stock, Preferred Stock and warrant included in each unit, as applicable.

PLAN OF DISTRIBUTION

We may sell the securities offered pursuant to this prospectus and applicable prospectus supplements in one or more of the following ways from time to time: (i) to or through underwriters or dealers, (ii) directly to one or more purchasers, including our affiliates, (iii) through agents, (iv) through a combination of any these methods, or (v) through any other method permitted by applicable law.

In addition, the manner in which we may sell some or all of the securities covered by this prospectus, includes, without limitation, through:

	●	an "at the market" offering, within the meaning of Rule 415(a)(4) of the Securities Act, to or through a market maker or into an existing trading market on an exchange or otherwise;
	●	a block trade in which a broker-dealer will attempt to sell as agent, but may position or resell a portion of the block, as principal, in order to facilitate the transaction;
	●	purchases by a broker-dealer, as principal, and resale by the broker-dealer for its account;
	●	ordinary brokerage transactions and transactions in which a broker solicits purchasers; or
	●	privately negotiated transactions.

The securities may be distributed from time to time in one or more transactions at a fixed price or prices, which may be changed, based on market prices prevailing at the time of sale, prices related to the prevailing market prices, or negotiated prices. The prospectus supplement relating to an offering of securities will set forth the terms of such offering, including:

	●	the name or names of any underwriters or agents;
	●	the name or names of any managing underwriter or underwriters;
	●	the name or names of any broker/dealers or placement agents;
	●	the purchase price of the securities;
	●	any over-allotment options under which underwriters may purchase additional securities;
	●	the net proceeds to us from the sale of the securities;
	●	any delayed delivery arrangements;
	●	any underwriting discounts, commissions and other items constituting underwriters' compensation;
	●	any initial public offering price;
	●	any discounts or concessions allowed or reallowed or paid to dealers;
	●	any commissions paid to agents; and
	●	any securities exchange or market on which the securities may be listed.

Sales Through Underwriters or Dealers

If underwriters are used in the sale, the underwriters will acquire the securities for their own account. We will enter into an underwriting agreement with those underwriters at the time of sale to them. We will set forth the names of the underwriters and the terms of the transaction in a prospectus supplement, which will be used by the underwriters to make resales of the securities in respect of which this prospectus is delivered to the public. The underwriters may resell the securities from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. Underwriters may sell the securities in order to facilitate transactions in any of our other securities (described in this prospectus or otherwise), including other public or private transactions and short sales. Underwriters may offer securities to the public either through underwriting syndicates represented by one or more managing underwriters or directly by one or more firms acting as underwriters without a syndicate. Unless otherwise indicated in a prospectus supplement, the obligations of the underwriters to purchase the securities will be subject to certain conditions, and the underwriters will be obligated to purchase all the offered securities if they purchase any of them. The underwriters may change from time to time any public offering price and any discounts or concessions allowed or reallowed or paid to dealers.

If dealers are used in the sale of securities offered through this prospectus, we will sell the securities to them as principals. The dealers may then resell those securities to the public at varying prices determined by the dealers at the time of resale. The prospectus supplement will include the names of the dealers and the terms of the transaction.

The maximum compensation or discount to be received by any FINRA member or independent broker-dealer will not be greater than 8% for the sale of any securities being registered hereunder pursuant to Rule 415 of the Securities Act.

Direct Sales

We may sell the securities offered pursuant to this prospectus directly. In this case, no underwriters or agents would be involved. We may sell the securities directly to institutional investors or others who may be deemed to be underwriters within the meaning of the Securities Act, with respect to any sale of those securities. We may use electronic media, including the Internet, to sell offered securities directly. The terms of any such sales will be described in a prospectus supplement.

Sales Through Agents

Securities offered by us pursuant to this prospectus may be sold through agents designated by us. Any such agent may be deemed to be an underwriter as that term is defined in the Securities Act. Any applicable prospectus supplement will name any agent involved in the offer or sale of the offered securities and will describe any commissions payable to the agent. Unless otherwise indicated in the prospectus supplement, any such agent will agree to use its reasonable best efforts to solicit purchases for the period of its appointment.

Delayed Delivery Arrangements

If an applicable prospectus supplement indicates, we may authorize agents, underwriters or dealers to solicit offers from certain institutional investors to purchase securities at the public offering price under delayed delivery contracts. Institutional investors to which such offers may be made, when authorized, include commercial and savings banks, insurance companies, pension funds, investment companies, education and charitable institutions and such other institutions as may be approved by us. The obligations of any such purchasers under such delayed delivery and payment arrangements will be subject to the condition that the purchase of the offered securities will not, at the time of delivery, be prohibited under applicable law. The underwriters and such agents will not have any responsibility with respect to the validity or performance of such contracts. The applicable prospectus supplement will describe the commission payable for solicitation of those contracts.

Market Making, Stabilization and Other Transactions

We may elect to list offered securities on an exchange or in the over-the-counter market. Any underwriters that we use in the sale of offered securities may make a market in such securities, but may discontinue such market making at any time without notice. Therefore, we cannot assure you that the securities will have a liquid trading market.

Certain persons participating in an offering may engage in overallotment, stabilizing transactions, syndicate covering transactions and penalty bids in accordance with rules and regulations under the Exchange Act. Overallotment involves the sale in excess of the offering size, which creates a short position. Stabilizing transactions involve bids to purchase the underlying security in the open market for the purpose of pegging, fixing or maintaining the price of the securities. Syndicate covering transactions involve purchases of the securities in the open market after the distribution has been completed in order to cover syndicate short positions.

Penalty bids permit the underwriters to reclaim a selling concession from a syndicate member when the securities originally sold by the syndicate member are purchased in a syndicate covering transaction to cover syndicate short positions. Stabilizing transactions, syndicate covering transactions and penalty bids may cause the price of the securities to be higher than it would be in the absence of the transactions. The underwriters may, if they commence these transactions, discontinue them at any time.

General Information

Underwriters, dealers and agents that participate in the distribution of the offered securities may be deemed to be underwriters as defined in the Securities Act, and any discounts or commissions received by them from us and any profit on the resale of the offered securities by them may be treated as underwriting discounts and commissions as such terms are defined under the Securities Act. Any underwriters or agents will be identified, and their compensation described, in the applicable prospectus supplement.

The securities (other than common stock) offered by this prospectus and any prospectus supplement, when first issued, will have no established trading market. Any underwriters or agents to or through whom such securities are sold by us for public offering and sale may make a market in such securities, but such underwriters or agents will not be obligated to do so and may discontinue any market making at any time without notice. We cannot assure you as to the liquidity of the trading market for any such securities.

Agents, underwriters, and dealers may be entitled, under agreements entered into with us, to indemnification by us against certain liabilities, including liabilities under the Securities Act, or to contribute with respect to payments that the underwriters, dealers or agents may be required to make.

Agents, underwriters, and dealers may engage in transactions with, or perform services for, us or our subsidiaries in the ordinary course of their businesses.

LEGAL MATTERS

Holland & Hart LLP, Denver, Colorado, or other counsel selected by the Company with regard to a particular offering, who will be named in the prospectus supplement relating to that offering, will pass upon the validity of any securities we offer by this prospectus. If the validity of any securities is also passed upon by counsel for the underwriters of an offering of those securities, that counsel will be named in the prospectus supplement relating to that offering.

Overview

American Battery Technology Company (the "Company", "ABTC", "we" and "us") is an integrated critical minerals manufacturing company that is working to increase the domestic U.S. production of critical minerals, such as lithium, nickel, cobalt, manganese, copper, aluminum, and graphite through its exploration of new primary resources of critical minerals, the development and commercialization of new technologies for the extraction of these critical minerals from primary resources, and the commercialization of an internally developed integrated process for the recycling of lithium-ion batteries. Through this three-pronged approach the Company is working to both increase the domestic production of these critical minerals and to ensure that as these materials reach their end of life, the constituent elemental critical minerals are returned to the domestic manufacturing supply chain in a closed-loop fashion.

ABTC has won several competitive funding opportunities from the US Government, and has signed strategic partnership and supply agreements with some of the largest corporations in the world.

The Company's corporate headquarters are in Reno, Nevada, and its critical mineral exploration office is located in Tonopah, Nevada. The Company's critical mineral recycling factory is in McCarran, Nevada.

Corporate Information

The Company was incorporated as Oroplata Resources, Inc. under the laws of the State of Nevada on October 6, 2011, for the purpose of acquiring rights to mineral properties with the eventual objective of being a producing mineral company. On August 8, 2016, the Company formed Lithortech Resources Inc. as a wholly owned subsidiary to serve as its operating subsidiary for lithium resource exploration and mine development. On June 29, 2018, the Company changed the name of Lithortech Resources to LithiumOre Corp. ("LithiumOre"). On May 3, 2019, the Company changed its name to American Battery Metals Corporation. On August 12, 2021, the Company further changed its name to American Battery Technology Company, which better aligns with the Company's current business activities and future objectives.

Risk Factors		An investment in our common stock involves a high degree of risk. See the section entitled "Risk Factors" included in this prospectus supplement, the accompanying base prospectus and our Annual Report on Form 10-K for the fiscal year ended June 30, 2026, incorporated by reference herein, and any other risk factors described in the documents incorporated by reference herein, for a discussion of certain factors to consider carefully before deciding to invest in our common stock.

Unless we indicate otherwise, all information in this prospectus supplement is based on 142,577,758 shares of common stock outstanding as of September 11, 2026, and excludes, as of such date, approximately 12,993,277 shares of our common stock issuable upon the exercise of outstanding warrants, with a weighted average exercise price of $6.31 per share, and 11,941,476 shares of common stock issuable upon the vesting of outstanding restricted stock units. Unless otherwise stated, all information in this prospectus supplement assumes no exercise of the outstanding warrants described above into common stock.

RISK FACTORS

An investment in our common stock involves a high degree of risk. Before making an investment in our common stock, you should carefully consider the risks discussed under the heading "Risk Factors" in our most recent Annual Report on Form 10-K, which are incorporated herein by reference (other than, in each case, information furnished, rather than filed), as well as the information contained in this prospectus supplement and the accompanying base prospectus relating to this offering. Any of those risk factors could significantly and adversely affect our business, prospects, financial condition and results of operations, and the trading price of our common stock. Although we describe, and will describe, what we believe to be the principal risks related to our Company and the securities we offer, we can also be affected by risks we do not anticipate or do not think will have a material effect upon us. Please also read carefully the section entitled "Cautionary Statement Regarding Forward-Looking Statements."

RISKS RELATED TO THIS OFFERING

The number of shares of our common stock available for future issuance or sale could adversely affect the per share trading price of our common stock.

We cannot predict whether future issuances or sales of our common stock or the availability of shares for resale in the open market will decrease the per share trading price of our common stock. The issuance of a substantial number of shares of our common stock in the public market or the perception that such issuances might occur could adversely affect the per share trading price of our common stock.

The actual number of shares we will issue under the Sales Agreement, at any one time or in total, is uncertain.

Subject to certain limitations in the Sales Agreement and compliance with applicable law, we have the discretion to deliver instruction to the Sales Agent to sell shares of our common stock at any time throughout the term of the Sales Agreement. The number of shares that are sold through the Sales Agent after our instruction will fluctuate based on a number of factors, including the market price of our common stock during the sales period, the limits we set with the Sales Agent in any instruction to sell shares, and the demand for our common stock during the sales period. Because the price per share of each share sold will fluctuate during this offering, it is not currently possible to predict the number of shares that will be sold or the gross proceeds to be raised in connection with those sales.

The common stock offered hereby will be sold in "at the market offerings," and investors who buy shares at different times will likely pay different prices.

Investors who purchase shares in this offering at different times will likely pay different prices, and so may experience different levels of dilution, and different outcomes in their investment results. We will have discretion, subject to market demand, to vary the timing, prices, and numbers of shares sold in this offering. Investors may experience a decline in the value of the shares they purchase in this offering as a result of sales made at prices lower than the prices they paid.

The market price of our common stock has been, and may continue to be, highly volatile, and such volatility could cause the market price of our common stock to decrease and could cause you to lose some or all of your investment in our common stock.

During the fiscal year ended June 30, 2026, the market price of our common stock has fluctuated from a high of $11.33 per share to a low of $1.64 per share, and our stock price continues to fluctuate. The market price of our common stock may continue to fluctuate significantly in response to numerous factors, some of which are beyond our control, such as:

	●	our ability to generate revenue and develop a consistent customer base;
	●	our ability to develop and scale our proprietary technology;
	●	the announcement and acceptance of new products or technology or related enhancements by us or our competitors;
	●	developments concerning regulatory oversight and approvals;
	●	variations in our and our competitors' results of operations;

	●	successes or challenges in our collaborative arrangements or alternative funding sources;
	●	developments in our industry generally;
	●	future issuances of common stock or other securities;
	●	the addition or departure of key personnel;
	●	announcements by us or our competitors of acquisitions, investments or strategic alliances; and
	●	general market conditions and other factors, including factors unrelated to our operating performance.

Further, the stock market in general, and our industry in particular, has recently experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of companies with securities traded in those markets. Broad market and industry factors may seriously affect the market price of companies' stock, including ours, regardless of actual operating performance. The volatility of our common stock is further exacerbated due to its low trading volume. Continued market fluctuations could result in extreme volatility in the price of our common stock, which could cause a decline in the value of our common stock and the loss of some or all of your investment.

Management will have broad discretion as to the use of the proceeds from this offering, and we may not use the proceeds effectively.

We have not allocated specific amounts of the net proceeds from this offering for any specific purpose. Accordingly, our management will have broad discretion in the application of the net proceeds from this offering and could spend the proceeds in ways that you do not agree with or that do not improve our results of operations or enhance the value of our common stock. See "Use of Proceeds." Our failure to apply these funds effectively could have a material adverse effect on our business, financial results, operating results and/or cash flow and could cause the price of our common stock to decline.

Our outstanding options and warrants, and the availability for resale of certain of the underlying shares, may adversely affect the trading price of our common stock.

Our outstanding options and warrants could adversely affect our ability to obtain future financing or engage in certain mergers or other transactions, since the holders thereof may exercise them at a time when we may be able to obtain additional capital through a new offering of securities on terms more favorable to us than the terms of outstanding securities. For the life of the options and warrants, the holders have the opportunity to profit from a rise in the market price of our common stock without assuming the risk of ownership. The issuance of shares upon the exercise of outstanding options and warrants would also dilute the ownership interests of our existing stockholders.

Additional financing or future equity issuances may result in future dilution to our stockholders.

We expect that we will need to raise additional funds in the future to finance our growth, our current and planned initiatives, investment activities, and for other reasons. Any required additional financing may not be available on terms acceptable to us, or at all. If we raise additional funds by issuing equity securities, you may experience significant dilution of your ownership interest and the newly issued securities may have rights senior to those of the holders of our common stock. The price per share at which we sell additional securities in future transactions may be higher or lower than the price per share in this offering. Alternatively, if we raise additional funds by obtaining loans from third parties, the terms of those financing arrangements may include negative covenants or other restrictions on our business that could impair our operational flexibility and would also require us to fund additional interest expense. If adequate additional financing is not available when required or is not available on acceptable terms, we may be unable to successfully execute our business plan.

The sale or issuance of our common stock may cause dilution and the sale of the shares of common stock could cause the price of our common stock to fall.

We are not restricted from issuing additional securities in the future, including our common stock, securities that are convertible into or exchangeable for, or that represent the right to receive, our common stock or substantially similar securities. To the extent that we raise additional funds through the sale of equity or convertible debt securities, the issuance of such securities will result in dilution to our stockholders. We may sell our common stock or other securities at a price per share that is less than the price per share paid by investors in this offering, and investors purchasing our common stock or other securities in the future could have rights superior to existing stockholders. The price per share at which we sell additional shares of our common stock, or securities convertible or exchangeable into shares of our common stock, in future transactions may be higher or lower than the price per share paid by investors in this offering. Depending on market liquidity at the time, sales of such shares or other securities may cause the trading price of our common stock to fall.

USE OF PROCEEDS

We may issue and sell shares of our common stock having aggregate sales proceeds of up to $100,000,000 from time to time under this prospectus supplement and accompanying base prospectus and the Sales Agreement. The amount of proceeds from this offering will depend upon the number of shares of our common stock sold and the market price at which they are sold. There can be no assurance that we will be able to sell any shares under or fully utilize the Sales Agreement with the Sales Agent as a source of financing. Because there is no minimum offering amount required as a condition to close this offering, the net proceeds to us, if any, are not determinable at this time.

We intend to use the net proceeds, if any, from this offering for general corporate purposes and working capital. Our management will retain broad discretion in the allocation and use of the net proceeds of this offering, and investors will be relying on the judgment of our management with regard to the use of these net proceeds. The precise amount, use and timing of the application of such proceeds will depend upon our funding requirements and the availability and cost of other capital.

Pending our use of the net proceeds from this offering, we may invest the net proceeds of this offering in a variety of capital preservation investments, including but not limited to short-term, investment grade, interest bearing instruments and U.S. government securities.

DIVIDEND POLICY

We have never declared or paid any cash dividends on our Common Stock. We currently intend to retain all available funds and any future earnings to support our operations and finance the growth and development of our business. We do not intend to pay cash dividends on our Common Stock for the foreseeable future. Any future determination related to dividend policy will be made at the discretion of our Board of Directors.

The holders of the Series B and Series C Preferred Stock are entitled to receive an 8% per annum dividend on their stated value which can be paid in cash or Common Stock at the discretion of the Company (see descriptions of the Preferred Stock below). As of September 11, 2026, there were 0 shares of Series A Preferred Stock, 0 shares of Series B Preferred Stock, 0 shares of Series C Preferred Stock, and 0 shares of Series D Preferred Stock issued and outstanding.

The current and future holders of our Common Stock are entitled to receive dividends pro rata based on the number of shares held, when and if declared by our Board of Directors, from funds legally available for that purpose. Nevada Revised Statutes prohibits us from declaring dividends where, after giving effect to the distribution of the dividend, we would not be able to pay our debts as they become due in the ordinary course of business, or our total assets would be less than the sum of our total liabilities.

Our Articles of Incorporation and Bylaws do not contain provisions restricting our ability to pay dividends of our Common Stock.

CAPITALIZATION

The following table sets forth our consolidated cash and cash equivalents and capitalization as of June 30, 2026. Such information is set forth on the following basis:

Our Articles of Incorporation authorize the issuance of up to 251,666,667 shares, including 250,000,000 shares of common stock and 1,666,667 shares of preferred stock. We are not permitted to issue and sell a number of shares under this offering that would cause us to issue and sell more shares than we have authorized under our Articles of Incorporation.

PLAN OF DISTRIBUTION

We entered into the Sales Agreement with the Sales Agent under which we may issue and sell from time to time up to $100,000,000 of our common stock through or to the Sales Agent as sales agent or principal. This summary of the material provisions of the Sales Agreement does not purport to be a complete statement of its terms and conditions. The Sales Agreement was filed as an exhibit to a Current Report on Form 8-K dated April 3, 2024 and is incorporated herein by reference.

Upon delivery of a placement notice, the Sales Agent may offer the common stock subject to the terms and conditions of the Sales Agreement on a daily basis or as otherwise agreed upon by us and the Sales Agent. We will designate the maximum amount of common stock to be sold through the Sales Agent on a daily basis or otherwise determine such maximum amount together with the Sales Agent. Subject to the terms and conditions of the Sales Agreement, the Sales Agent will use its commercially reasonable efforts to sell on our behalf all of the shares of common stock requested to be sold by us. We may instruct the Sales Agent not to sell common stock if the sales cannot be effected at or above the price designated by us in any such instruction. We or the Sales Agent may suspend the offering of the common stock being made through the Sales Agent under the Sales Agreement upon proper notice to the other party and subject to other conditions.

We will pay the Sales Agent a commission, in cash, for its services in acting as agent in the sale of our common stock. The aggregate compensation payable to the Sales Agent will be equal to up to 3.0% of the gross sales price per share of all shares sold through the Sales Agent under the Sales Agreement. We also have agreed to reimburse the Sales Agent up to a maximum of $60,000 for its costs and expenses relating to the Sales Agreement, including legal expenses. Because there is no minimum offering amount required as a condition to close this offering, the actual total public offering amount, commissions and proceeds to us, if any, are not determinable at this time. The total expenses of the offering payable by us, excluding commissions payable to the Sales Agent under the Sales Agreement, is up to $60,000.

Unless the parties agree otherwise, settlement for sales of common stock will occur on the second business day following the date on which any sales are made, or on some other date that is agreed upon by us and the Sales Agent in connection with a particular transaction, in return for payment of the net proceeds to us. Sales of our common stock as contemplated in this prospectus supplement will be settled through the facilities of The Depository Trust Company or by such other means as we and the Sales Agent may agree upon. There is no arrangement for funds to be received in an escrow, trust or similar arrangement.

The Sales Agent is not required to sell any specific amount of securities, but will act as our sales agent using its commercially reasonable efforts, consistent with its sales and trading practices under the terms and subject to the conditions set forth in the Sales Agreement, to sell our common stock. In connection with the sales of our common stock on our behalf, the Sales Agent will be deemed to be an "underwriter" within the meaning of the Securities Act, and the compensation to them will be deemed to be underwriting commissions or discounts. We have also agreed in the Sales Agreement to provide indemnification and contribution to the Sales Agent with respect to certain liabilities, including liabilities under the Securities Act.

This offering of our common stock pursuant to the Sales Agreement will terminate automatically upon the sale of all shares of our common stock subject to the Sales Agreement and this prospectus supplement or as otherwise permitted therein. We and the Sales Agent may each terminate the Sales Agreement at any time upon ten days' prior written notice.

Our common stock is listed on The Nasdaq Stock Market LLC under the trading symbol "ABAT." The transfer agent for our common stock is Securities Transfer Corporation at 2901 N. Dallas Parkway, Suite 380, Plano, TX 75093. The transfer agent's telephone number is (469) 633-0101.

We will report at least quarterly the number of shares of common stock sold through the Sales Agent under the Sales Agreement, the net proceeds to us and the compensation paid by us to the Sales Agent in connection with the sales of shares of common stock during the relevant period.

This prospectus supplement and the accompanying base prospectus in electronic format may be made available on a website maintained by the Sales Agent, and the Sales Agent may distribute this prospectus supplement and the accompanying base prospectus electronically.

Other Relationships

The Sales Agent and its affiliates may in the future provide various investment banking, commercial banking and other financial services for us and our affiliates, for which services they may in the future receive customary fees. To the extent required by Regulation M, the Sales Agent will not engage in any market making activities involving our common stock while the offering is ongoing under this prospectus supplement.

Item 15. Indemnification of Directors and Officers

Nevada Law

Section 78.7502 of the Nevada Revised Statutes permits 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, except an action by or in the right of the corporation, by reason of the fact that he 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 or as a manager of a limited-liability company, against expenses, including attorneys' fees, judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with the action, suit or proceeding if he:

(a) is not liable pursuant to Nevada Revised Statute 78.138, or (b) acted in good faith and in a manner which he 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 conduct was unlawful.

In addition, Section 78.7502 permits 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 he 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 or as a manager of a limited-liability company, against expenses, including amounts paid in settlement and attorneys' fees actually and reasonably incurred by him in connection with the defense or settlement of the action or suit if he:

(a) is not liable pursuant to Nevada Revised Statute 78.138; or (b) acted in good faith and in a manner which he reasonably believed to be in or not opposed to the best interests of the corporation.

Section 78.751 of the Nevada Revised Statutes provides that to the extent that a director, officer, employee or agent of a corporation has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to above (or in defense of any claim, issue or matter therein), the corporation is required to indemnify him against expenses, including attorneys' fees, actually and reasonably incurred by him in connection with the defense.

Section 78.751 of the Nevada Revised Statutes also provides that (unless otherwise restricted by the articles of incorporation, the bylaws or an agreement made by the corporation) such indemnification may also include payment by the corporation of expenses incurred in defending a civil or criminal action or proceeding as they are incurred and in advance of the final disposition of such action or proceeding upon receipt of an undertaking by (or on behalf of) a director or officer to repay such payment if he shall be ultimately found not to be entitled to indemnification by the corporation. Indemnification may be provided even though the person to be indemnified is no longer a director, officer, employee or agent of the corporation or such other entities.

Section 78.752 of the Nevada Revised Statutes allows a corporation to purchase and maintain insurance or make other financial arrangements on behalf of any person who 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 for any liability asserted against him and liability and expenses incurred by him in his capacity as a director, officer, employee or agent, or arising out of his status as such, whether or not the corporation has the authority to indemnify him against such liability and expenses.

Other financial arrangements made by the corporation pursuant to Section 78.752 may include the following:

(a) the creation of a trust fund;

(b) the establishment of a program of self-insurance;

(c) the securing of its obligations of indemnification by granting a security interest or other lien on any assets of the corporation; and

(d) the establishment of a letter of credit, guaranty or surety.

No financial arrangement made pursuant to Section 78.752 may provide protection for a person adjudged by a court of competent jurisdiction, after exhaustion of all appeals, to be liable for intentional misconduct, fraud or a knowing violation of law, except with respect to the advancement of expenses of indemnification ordered by a court.

Any discretionary indemnification pursuant to Section 78.7502 of the Nevada Revised Statutes, unless ordered by a court or advanced pursuant to an undertaking to repay the amount if it is determined by a court that the indemnified party is not entitled to be indemnified by the corporation, may be made by the corporation only as authorized in the specific case upon a determination that indemnification of the director, officer, employee or agent is proper under the circumstances. The determination must be made by:

(a) the stockholders;

(b) the board of directors by a majority vote of a quorum consisting of directors who were not parties to the action, suit or proceeding;

(c) independent legal counsel in a written opinion if a majority vote of a quorum consisting of directors who were not parties to the action, suit or proceeding so orders; or

(d) independent legal counsel in a written opinion if a quorum consisting of directors who were not parties to the action, suit or proceeding cannot be obtained.

Subsection 7 of Section 78.138 of the Nevada Revised Statutes provides that, subject to certain very limited statutory exceptions or unless the articles of incorporation or an amendment thereto provide for greater individual liability, 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 or her capacity as a director or officer, unless it is proven that the act or failure to act constituted a breach of his or her fiduciary duties as a director or officer and such breach of those duties involved intentional misconduct, fraud or a knowing violation of law.

Charter Provisions and Other Arrangements

Pursuant to the provisions of Nevada Revised Statutes, we have adopted the following indemnification provisions in our Articles of Incorporation for our directors and officers:

Officers and directors shall have no personal liability to the corporation or its stockholders for damages for breach of fiduciary duty as an officer or director. This provision does not eliminate or limit the liability of an officer or director for acts or omissions which involve intentional misconduct, fraud or a knowing violation of law or the payment of distributions in violation of the NRS 78.300.

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 SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable.

Item 17. Undertakings

a. The undersigned registrant hereby undertakes:

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 of 1933;

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 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement.

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) of this section do not apply if the registration statement is on Form S-3 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 Securities Exchange Act of 1934 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 of 1933, 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 of 1933 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 of 1933 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 the 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 that 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.

5. That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities:

The undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

i. Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

ii. Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

iii. The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

iv. Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

b. The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant's annual report pursuant to section 13(a) or section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to section 15(d) of the Securities Exchange Act of 1934) 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. The undersigned registrant hereby undertakes to deliver or cause to be delivered with the prospectus, to each person to whom the prospectus is sent or given, the latest annual report to security holders that is incorporated by reference in the prospectus and furnished pursuant to and meeting the requirements of Rule 14a-3 or Rule 14c-3 under the Securities Exchange Act of 1934; and, where interim financial information required to be presented by Article 3 of Regulation S-X are not set forth in the prospectus, to deliver, or cause to be delivered to each person to whom the prospectus is sent or given, the latest quarterly report that is specifically incorporated by reference in the prospectus to provide such interim financial information.

d. Insofar as indemnification for liabilities arising under the Securities Act of 1933 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.

e. If and when applicable, the Registrant hereby further undertakes to file an application for the purpose of determining the eligibility of the trustee to act under subsection (a) of Section 310 of the Trust Indenture Act in accordance with the rules and regulations prescribed by the Securities and Exchange Commission under Section 305(b)(2) of the Trust Indenture Act.

SIGNATURES

Pursuant to the requirements of the Securities Act of 1933, as amended, 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 Reno, State of Nevada, on September 18, 2026.
