EXPLANATORY NOTE

Post-Effective Amendment No. 1 to the Registration Statement on Form S-3 (File No. 333-254290) of CleanSpark, Inc., or the Company, was filed because the Company expected that it would no longer be a “well-known seasoned issuer” (as such term is defined in Rule 405 of the Securities Act of 1933, as amended, or the Securities Act) when it filed its Annual Report on Form 10-K for the fiscal year ended September 30, 2022. Accordingly, the Company filed Post-Effective Amendment No. 1 for the purpose of including disclosure required for a registrant other than a well-known seasoned issuer, identifying the securities being registered, registering a specific amount of securities and paying the associated filing fee. This Post-Effective Amendment No. 2 to the Registration Statement on Form S-3 (“Post-Effective Amendment No. 2”) is being filed using EDGAR submission type POS AM in order to convert the Registration Statement to the proper EDGAR submission type for a non-automatic shelf registration statement.

This Post-Effective Amendment No. 2 contains:

• a base prospectus, which covers the offering, sale and issuance by us of up to $500,000,000 of the securities identified below from time to time in one or more offerings;

• a sales agreement prospectus supplement covering the offering, issuance and sale by us of up to a maximum aggregate offering price of $500,000,000 of our common stock that may be issued and sold from time to time under a sales agreement with H.C. Wainwright & Co., LLC, or Wainwright; and

• a selling shareholder prospectus covering the offer and sale, from time to time, in one or more offerings, of 2,691,065 shares of our common stock by the selling shareholder named therein.

The base prospectus immediately follows this explanatory note. The specific terms of any other securities to be offered pursuant to the base prospectus will be specified in one or more prospectus supplements to the base prospectus. The sales agreement prospectus supplement immediately follows the base prospectus. The selling shareholder prospectus immediately follows the sales agreement prospectus supplement.

The $500,000,000 of common stock that may be offered, issued and sold under the sales agreement prospectus supplement is included in the $500,000,000 of securities that may be offered, issued and sold by us under the base prospectus. Upon termination of the sales agreement with Wainwright, any portion of the $500,000,000 of common stock included in the sales agreement prospectus supplement that is not sold pursuant to the sales agreement will be available for sale in other offerings pursuant to the base prospectus and a corresponding prospectus supplement, and if no shares are sold under the sales agreement, the full $500,000,000 of securities may be sold in other offerings pursuant to the base prospectus and a corresponding prospectus supplement.

This registration statement also contains the selling shareholder prospectus to be used in connection with the offer and sale, from time to time, in one or more offerings, of 2,691,065 shares of our common stock by the selling shareholder named therein.

The information in this preliminary prospectus is not complete and may be changed. We may not sell these securities until the U.S. Securities and Exchange Commission declares our registration statement effective. This preliminary prospectus is not an offer to sell these securities and we are not soliciting offers to buy these securities in any state or jurisdiction where the offer or sale is not permitted.

This prospectus is part of a registration statement that we filed with the U.S. Securities and Exchange Commission, or the SEC, utilizing a “shelf” registration process. By using a shelf registration statement, we may sell securities from time to time and in one or more offerings as described in this prospectus for an aggregate offering price of up to $500,000,000. This prospectus provides you with a general description of the securities we may offer. Each time that we offer and sell securities, we will provide a prospectus supplement to this prospectus that contains specific information about the securities being offered and sold and the specific terms of that offering. 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 or free writing prospectus may also add, update or change information contained in this prospectus with respect to that offering. If there is any inconsistency between the information in this prospectus and the applicable prospectus supplement or free writing prospectus, you should rely on the prospectus supplement or free writing prospectus, as applicable. However, no prospectus supplement will offer a security that is not registered and described in this prospectus at the time of its effectiveness.

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.

THE COMPANY

Overview

CleanSpark, Inc. is a leading sustainable bitcoin mining company incorporated in Nevada, whose common stock is listed on the Nasdaq Capital Market. The Company, through itself and its wholly owned subsidiaries, has operated in the digital currency mining industry since December 2020.

We are currently working with various industry participants in developing a long-term sustainability and clean energy plan for our bitcoin mining operations. As part of this plan, we are using the available clean and renewable energy resources that we currently have reasonable access to at our bitcoin mining locations in order to further support our sustainability efforts.

Through CleanSpark, Inc., and our wholly owned subsidiaries ATL Data Centers LLC (“ATL”), CleanBlok, Inc. (“CleanBlok”), CleanSpark DW, LLC, and CleanSpark GLP, LLC, we mine bitcoin. We entered the bitcoin mining industry through our acquisition of ATL in December 2020, acquired a second data center in August 2021, a third data center and mining equipment in August 2022, a fourth data center and mining equipment in October 2022, and have had a co-location agreement with New York-based Coinmint in place since July 2021. Bitcoin mining has now become our principal revenue generating business activity. We currently intend to continue to acquire additional facilities, equipment and infrastructure capacity to continue to expand our bitcoin mining operations.

In August 2022, we completed the acquisition of certain real property located in Wilkes County, Georgia, and approximately 3,400 S19 and S19j Pro series bitcoin miners capable of providing computing power of approximately 341,000 terahash per second. The property acquired provided us with a turn-key data center campus capable of supporting approximately 1 exahash per second of computing power, upon closing of the acquisition. We expect to expand the campus to support approximately 2.6 exahash per second of computing power (collectively, the “WAHA and SPRE Assets”).

In October 2022, we acquired the lease for 16.35 acres of real property located in Sandersville, Washington County, Georgia, all personal property situated on such property, and 6,349 application specific integrated circuit miners (“ASICs”) capable of providing computing power of approximately 530,000 terahash per second from subsidiaries of Mawson Infrastructure Group, Inc. The property acquired provided the Company with a turn-key data center campus capable of supporting approximately 2.4 exahash per second of computing power, upon closing of the acquisition. The company expects to expand the campus to support approximately 7.0 exahash per second of computing power (collectively, the “Mawson Assets”).

RISK FACTORS

An investment in our securities involves a high degree of risk. The prospectus supplement applicable to each offering of securities will contain a discussion of the risks applicable to an investment in our securities. Prior to making a decision about investing in our securities, you should carefully consider the specific factors discussed under the heading “Risk Factors” in the applicable prospectus supplement, together with all of the other information contained or incorporated by reference in the prospectus supplement or appearing or incorporated by reference in this prospectus. You should also consider the risks, uncertainties and assumptions discussed under the heading “Risk Factors,” in our most recent Annual Report on Form 10-K, which may be amended, supplemented or superseded from time to time by other reports we file with the SEC in the future. The risks and uncertainties we have described are not the only ones we face. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also affect our operations.

4

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus and the documents incorporated herein by reference contain “forward-looking statements” within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act about us and our industry that involve substantial risks and uncertainties. All statements other than statements of historical fact contained in this document and the materials accompanying this document are forward-looking statements. These statements are based on current expectations of future events. Frequently, but not always, forward-looking statements are identified by the use of the future tense and by words such as “believes,” “expects,” “anticipates,” “intends,” “will,” “may,” “could,” “would,” “projects,” “continues,” “estimates” or similar expressions. Forward-looking statements are not guarantees of future performance and actual results could differ materially from those indicated by such forward-looking statements. Forward-looking statements involve known and unknown risks, uncertainties, and other factors that may cause our or our industry’s actual results, levels of activity, performance, or achievements to be materially different from any future results, levels of activity, performance, or achievements expressed or implied by the forward-looking statements. These forward-looking statements speak only as of the date made and are subject to a number of known and unknown risks, uncertainties and assumptions, including the important factors incorporated by reference into this prospectus from 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 we file after the date of this prospectus, and all other information contained or incorporated by reference into this prospectus, as updated by our subsequent filings under the Exchange Act and in our other filings with the SEC, that may cause our actual results, performance or achievements to differ materially and adversely from those expressed or implied by the forward-looking statements.

Because forward-looking statements are inherently subject to risks and uncertainties, some of which cannot be predicted or quantified and some of which are beyond our control, you should not rely on these forward-looking statements as predictions of future events. The events and circumstances reflected in our forward-looking statements may not be achieved or occur and actual results could differ materially from those projected in the forward-looking statements. Moreover, we operate in an evolving environment. New risk factors and uncertainties may emerge from time to time, and it is not possible for management to predict all risk factors and uncertainties. Except as required by applicable law, we do not plan to publicly update or revise any forward-looking statements, whether as a result of any new information, future events, changed circumstances or otherwise.

USE OF PROCEEDS

Except as otherwise set forth in any accompanying prospectus supplement, we expect to use the net proceeds from the sale of securities for general corporate purposes, which may include funding our future development, strategic acquisitions or other significant corporate transactions.

DESCRIPTION OF CAPITAL STOCK

The following description sets forth certain general terms and provisions of the common stock and preferred stock to which any prospectus supplement may relate. This description is summarized from, and qualified in its entirety by reference to, the applicable provisions of Nevada Revised Statutes (“NRS”) Chapters 78 and 92A and our articles of incorporation and bylaws, each as amended, which are incorporated by reference as exhibits to the registration statement of which this prospectus forms a part.

In this “Description of Capital Stock” section, when we refer to “we,” “us” or “our” or when we otherwise refer to ourselves, we mean CleanSpark, Inc., excluding, unless otherwise expressly stated or the context requires, our subsidiaries.

General

Our articles of incorporation authorize us to issue up to 100,000,000 shares of common stock, $0.001 par value per share, and 10,000,000 shares of preferred stock, $0.001 par value per share.

As of December 12, 2022, there were 71,308,381 shares of common stock outstanding and 1,750,000 shares of our Series A Preferred Stock outstanding.

Common Stock

Voting rights. Each holder of our common stock is entitled to one vote for each share on all matters submitted to a vote of the stockholders, including the election of directors. Our stockholders do not have cumulative voting rights in the election of directors. Directors are elected by a plurality of the votes cast at the meeting of stockholders.

Dividends. Subject to preferences that may be applicable to any then-outstanding preferred stock, holders of common stock are entitled to receive ratably those dividends, if any, as may be declared from time to time by our Board out of legally available funds. We have never declared or paid any cash dividends on our common stock. We currently intend to retain future earnings, if any, to finance the expansion of our business. As a result, we do not anticipate paying any cash dividends in the foreseeable future.

Liquidation. In the event of our liquidation, dissolution or winding up of the Company, holders of common stock are entitled to share ratably in the net assets legally available for distribution to stockholders after the payment of all of our debts and other liabilities and the satisfaction of any liquidation preference granted to the holders of any then-outstanding shares of preferred stock.

Rights and preferences. Holders of common stock have no preemptive, conversion or subscription rights and there are no redemption or sinking fund provisions applicable to the common stock. The rights, preferences and privileges of the holders of common stock are subject to, and may be adversely affected by, the rights of the holders of shares of any series of our preferred stock, including any series of preferred stock that our board of directors may designate in the future.

Fully paid and nonassessable. All of our outstanding shares of common stock are, and the shares of common stock to be issued in this offering, if any, will be, upon payment therefor, fully paid and nonassessable.

Preferred Stock

Under our articles of incorporation, as amended, our Board has the authority, without further action by the stockholders (unless such stockholder action is required by applicable law or the rules of any stock exchange or market on which our securities are then traded), to designate and issue up to 10,000,000 shares of preferred stock in one or more series, to establish from time to time the number of shares to be included in each such series, to

7

fix the designations, voting powers, preferences and rights of the shares of each wholly unissued series, and any qualifications, limitations or restrictions thereof, and to increase or decrease the number of shares of any such series, but not below the number of shares of such series then outstanding.

We will fix the designations, voting powers, preferences and rights of the preferred stock of each series, as well as the qualifications, limitations or restrictions thereof, in a certificate of designation relating to that series. We will file as an exhibit to our reports, or will incorporate by reference from reports that we file with the SEC, the form of any certificate of designation that describes the terms of the series of preferred stock we are offering before the issuance of that series of preferred stock. This description will include, as applicable:

• the title and stated value, if any;

• the number of shares we are offering;

• the liquidation preference, if any, per share;

• the purchase price;

• the dividend rate, period and payment date and method of calculation for dividends;

• whether dividends, if any, will be cumulative or non-cumulative and, if cumulative, the date from which dividends will accumulate;

• the procedures for any auction and remarketing, if any;

• the provisions for a sinking fund, if any;

• the provisions for redemption or repurchase, if applicable, and any restrictions on our ability to exercise those redemption and repurchase rights;

• any listing of the preferred stock on any securities exchange or market;

• whether the preferred stock will be convertible into our common stock, and, if applicable, the conversion price, or how it will be calculated, and the conversion period;

• whether the preferred stock will be exchangeable into debt securities, and, if applicable, the exchange price, or how it will be calculated, and the exchange period;

• voting rights, if any;

• preemptive rights, if any;

• restrictions on transfer, sale or other assignment, if any;

• a discussion of any material U.S. federal income tax considerations applicable to the preferred stock;

• the relative ranking and preferences of the preferred stock as to dividend rights and rights if we liquidate, dissolve or wind up our affairs;

• any limitations on the issuance of any class or series of preferred stock ranking senior to or on a parity with the series of preferred stock as to dividend rights and rights if we liquidate, dissolve or wind up our affairs; and

• any other specific terms, preferences, rights or limitations of, or restrictions on, the preferred stock.

Nevada law provides that, unless such right to vote is specifically denied in the articles of incorporation (including any applicable certificate of designation), any proposed amendment to our articles of incorporation that would adversely alter or change any preference or any relative or other right given to any class or series of outstanding shares, then, in addition to any approval otherwise required, the amendment must be approved by the holders of shares representing a majority of the voting power of each class or series adversely affected by the amendment regardless of limitations or restrictions on the voting power of the class or series.

8

Our Board may authorize the issuance of preferred stock with voting, exchange or conversion rights that could adversely affect the voting power or other rights of the holders of our common stock. Preferred stock could be issued quickly with terms designed to delay or prevent a change in control of the Company or make removal of management more difficult. Additionally, the issuance of preferred stock may have the effect of decreasing the market price of our common stock.

Series A Preferred Stock

On April 15, 2015, pursuant to the authority granted under our articles of incorporation, our board of directors designated a series of preferred stock as Series A Preferred Stock, consisting of up to one million (1,000,000) shares, par value $0.001. Under the certificate of designation for the Series A Preferred Stock, holders of Series A Preferred Stock will be entitled to quarterly dividends on 2% of our earnings before interest, taxes and amortization. The dividends are payable in cash or common stock. The holders will also have a liquidation preference on the stated value of $0.02 per share plus any accumulated but unpaid dividends. The holders are further entitled to have the Company redeem each share of Series A Preferred Stock for three shares of our common stock if a change of control event (as defined in the certificate of designation) occurs, and they are entitled to vote together with the holders of the Company’s common stock on all matters submitted to stockholders at a rate of forty-five (45) votes for each share of Series A Preferred Stock held.

On October 9, 2019, the certificate of designation for the Series A preferred Stock was amended to increase the number of shares of preferred stock designated as Series A Preferred Stock from one million (1,000,000) shares to two million (2,000,000) shares.

Stock Options

The Company sponsors a stock-based incentive compensation plan known as the 2017 Incentive Plan (the “2017 Plan”), which was established by the Board of Directors of the Company on June 19, 2017. A total of 300,000 shares were initially reserved for issuance under the 2017 Plan. On October 7, 2020, the Company executed an amendment to the 2017 Plan to increase the reserved option pool to 1,500,000 shares, and on September 15, 2021, the Company executed a second amendment to the 2017 Plan to increase the number of share of common stock authorized for issuance under the 2017 Plan by an additional 2,000,000 shares.

The 2017 Plan allows the Company to grant incentive stock options, non-qualified stock options, stock appreciation rights, restricted stock and stock units. The incentive stock options are exercisable for up to ten years, at an option price per share not less than the fair market value on the date the option is granted. The incentive stock options are limited to persons who are regular full-time employees of the Company at the date of the grant of the option. Non-qualified options may be granted to any person, including, but not limited to, employees, independent agents, consultants and attorneys, who the Company’s Board believes have contributed, or will contribute, to the success of the Company.

Earn-out Shares

On October 8, 2022, we completed the acquisition of a lease for approximately 16.35 acres of real property located in Sandersville, Washington County, Georgia (the “Property”), all personal property situated on the Property and 6,349 application-specific integrated circuit miners from subsidiaries of Mawson Infrastructure Group, Inc. a Delaware corporation (“Mawson”), all pursuant to a Purchase and Sale Agreement, dated September 8, 2022 (as amended, the “Purchase Agreement”) and an Equipment Purchase and Sale Agreement dated September 8, 2022.

As part of the consideration for the Property, the Company issued 1,590,175 shares of the Company’s common stock (the “Closing Date Shares”) to Mawson. In addition, the Company may issue up to 1,100,890 additional shares of its common stock (the “Earn-out Shares”) to Mawson pursuant to earn out provisions in the Purchase Agreement.

Registration Rights

On September 8, 2022, the Company agreed to register 2,691,065 shares of common stock issued to Mawson in connection with the Purchase Agreement.

Anti-Takeover Laws

The NRS contain provisions governing the acquisition of a controlling interest in certain Nevada corporations. Nevada’s “acquisition of controlling interest” statutes (NRS 78.378 through 78.3793, inclusive) contain provisions governing the acquisition of a controlling interest in certain Nevada corporations. These “control share” laws provide generally that any person that acquires a “controlling interest” in certain Nevada corporations may be denied voting rights, unless a majority of the disinterested stockholders of the corporation elects to restore such voting rights. These laws will apply to us as of a particular date if we were to have 200 or more stockholders of record (at least 100 of whom have addresses in Nevada appearing on our stock ledger at all times during the 90 days immediately preceding that date) and do business in the State of Nevada directly or through an affiliated corporation, unless our articles of incorporation or bylaws in effect on the tenth day after the acquisition of a controlling interest provide otherwise. These laws provide that a person acquires a “controlling interest” whenever a person acquires shares of a subject corporation that, but for the application of these provisions of the NRS, would enable that person to exercise (1) one-fifth or more, but less than one-third, (2) one-third or more, but less than a majority or (3) a majority or more, of all of the voting power of the corporation in the election of directors. Once an acquirer crosses one of these thresholds, shares which it acquired in the transaction taking it over the threshold and within the 90 days immediately preceding the date when the acquiring person acquired or offered to acquire a controlling interest become “control shares” to which the voting restrictions described above apply. These laws may have a chilling effect on certain transactions if our articles of incorporation or bylaws are not timely amended to provide that these provisions do not apply to us or to an acquisition of a controlling interest, or if our disinterested stockholders do not confer voting rights in the control shares.

Nevada’s “combinations with interested stockholders” statutes (NRS 78.411 through 78.444, inclusive) provide that specified types of business “combinations” between certain Nevada corporations and any person deemed to be an “interested stockholder” of the corporation are prohibited for two years after such person first becomes an “interested stockholder” unless the corporation’s board of directors approves the combination (or the transaction by which such person becomes an “interested stockholder”) in advance, or unless the combination is approved by the board of directors and sixty percent of the corporation’s voting power not beneficially owned by the interested stockholder, its affiliates and associates. Furthermore, in the absence of prior approval certain restrictions may apply even after such two-year period. For purposes of these statutes, an “interested stockholder” is any person who is (1) the beneficial owner, directly or indirectly, of 10% or more of the voting power of the outstanding voting shares of the corporation, or (2) an affiliate or associate of the corporation and at any time within the two previous years was the beneficial owner, directly or indirectly, of 10% or more of the

10

voting power of the then-outstanding shares of the corporation. The definition of the term “combination” is sufficiently broad to cover most significant transactions between a corporation and an “interested stockholder”. These laws generally apply to Nevada corporations with 200 or more stockholders of record. However, a Nevada corporation may elect in its articles of incorporation not to be governed by these particular laws, but if such election is not made in the corporation’s original articles of incorporation, the amendment (1) must be approved by the affirmative vote of the holders of stock representing a majority of the outstanding voting power of the corporation not beneficially owned by interested stockholders or their affiliates and associates, and (2) is not effective until 18 months after the vote approving the amendment and does not apply to any combination with a person who first became an interested stockholder on or before the effective date of the amendment. We have not made such an election in our original articles of incorporation and we have not amended our articles of incorporation to so elect.

Further, NRS 78.139 also provides that directors may resist a change or potential change in control of the corporation if the board of directors determines that the change or potential change is opposed to or not in the best interest of the corporation upon consideration of any relevant facts, circumstances, contingencies or constituencies pursuant to NRS 78.138(4).

DESCRIPTION OF DEBT SECURITIES

We may issue debt securities from time to time, in one or more series, as either senior or subordinated debt or as senior or subordinated convertible debt. While the terms we have summarized below will apply generally to any debt securities that we may offer under this prospectus, we will describe the particular terms of any debt securities that we may offer in more detail in the applicable prospectus supplement. The terms of any debt securities offered under a prospectus supplement may differ from the terms described below. Unless the context requires otherwise, whenever we refer to the indenture, we also are referring to any supplemental indentures that specify the terms of a particular series of debt securities.

We will issue the debt securities under the indenture that we will enter into with the trustee named in the indenture. The indenture will be qualified under the Trust Indenture Act of 1939, as amended, or the Trust Indenture Act. We have filed the form of indenture as an exhibit to the registration statement of which this prospectus is a part, and supplemental indentures and forms of debt securities containing the terms of the debt securities being offered will be filed as exhibits to the registration statement of which this prospectus is a part or will be incorporated by reference from reports that we file with the SEC.

The following summary of material provisions of the debt securities and the indenture is subject to, and qualified in its entirety by reference to, all of the provisions of the indenture applicable to a particular series of debt securities. We urge you to read the applicable prospectus supplements and any related free writing prospectuses related to the debt securities that we may offer under this prospectus, as well as the complete indenture that contains the terms of the debt securities.

General

The indenture does not limit the amount of debt securities that we may issue. It provides that we may issue debt securities up to the principal amount that we may authorize and may be in any currency or currency unit that we may designate. Except for the limitations on consolidation, merger and sale of all or substantially all of our assets contained in the indenture, the terms of the indenture do not contain any covenants or other provisions designed to give holders of any debt securities protection against changes in our operations, financial condition or transactions involving us.

We may issue the debt securities issued under the indenture as “discount securities,” which means they may be sold at a discount below their stated principal amount. These debt securities, as well as other debt securities that are not issued at a discount, may be issued with “original issue discount,” or OID, for U.S. federal income tax purposes because of interest payment and other characteristics or terms of the debt securities. Material U.S. federal income tax considerations applicable to debt securities issued with OID will be described in more detail in any applicable prospectus supplement.

We will describe in the applicable prospectus supplement the terms of the series of debt securities being offered, including:

• the denominations in which we will issue the series of debt securities, if other than denominations of $1,000 and any integral multiple thereof;

• any and all terms, if applicable, relating to any auction or remarketing of the debt securities of that series and any security for our obligations with respect to such debt securities and any other terms which may be advisable in connection with the marketing of debt securities of that series;

• whether the debt securities of the series shall be issued in whole or in part in the form of a global security or securities; the terms and conditions, if any, upon which such global security or securities may be exchanged in whole or in part for other individual securities; and the depositary for such global security or securities;

• whether interest will be payable in cash or additional debt securities at our or the holders’ option and the terms and conditions upon which the election may be made;

13

• the terms and conditions, if any, upon which we will pay amounts in addition to the stated interest, premium, if any, and principal amounts of the debt securities of the series to any holder that is not a “United States person” for federal tax purposes;

• any other specific terms, preferences, rights or limitations of, or restrictions on, the debt securities, any other additions or changes in the provisions of the indenture, and any terms that may be required by us or advisable under applicable laws or regulations

Conversion or Exchange Rights

We will set forth in the applicable prospectus supplement the terms on which a series of debt securities may be convertible into or exchangeable for our common stock or our other securities. We will include provisions as to settlement upon conversion or exchange and whether conversion or exchange is mandatory, at the option of the holder or at our option. We may include provisions pursuant to which the number of shares of our common stock or our other securities that the holders of the series of debt securities receive would be subject to adjustment.

Consolidation, Merger Or Sale

Unless we provide otherwise in the prospectus supplement applicable to a particular series of debt securities, the indenture will not contain any covenant that restricts our ability to merge or consolidate, or sell, convey, transfer or otherwise dispose of our assets as an entirety or substantially as an entirety. However, any successor to or acquirer of such assets (other than a subsidiary of ours) must assume all of our obligations under the indenture or the debt securities, as appropriate.

Events Of Default Under The Indenture

Unless we provide otherwise in the prospectus supplement applicable to a particular series of debt securities, the following are events of default under the indenture with respect to any series of debt securities that we may issue:

• if we fail to pay any installment of interest on any series of debt securities, as and when the same shall become due and payable, and such default continues for a period of 90 days; provided, however, that a valid extension of an interest payment period by us in accordance with the terms of any indenture supplemental thereto shall not constitute a default in the payment of interest for this purpose;

• if we fail to pay the principal of, or premium, if any, on any series of debt securities as and when the same shall become due and payable whether at maturity, upon redemption, by declaration or otherwise, or in any payment required by any sinking or analogous fund established with respect to such series; provided, however, that a valid extension of the maturity of such debt securities in accordance with the terms of any indenture supplemental thereto shall not constitute a default in the payment of principal or premium, if any;

• if we fail to observe or perform any other covenant or agreement contained in the debt securities or the indenture, other than a covenant specifically relating to another series of debt securities, and our failure continues for 90 days after we receive written notice of such failure, requiring the same to be remedied and stating that such is a notice of default thereunder, from the trustee or holders of at least 25% in aggregate principal amount of the outstanding debt securities of the applicable series; and

• if specified events of bankruptcy, insolvency or reorganization occur.

If an event of default with respect to debt securities of any series occurs and is continuing, other than an event of default specified in the last bullet point above, the trustee or the holders of at least 25% in aggregate principal amount of the outstanding debt securities of that series, by notice to us in writing, and to the trustee if

14

notice is given by such holders, may declare the unpaid principal of, premium, if any, and accrued interest, if any, of such series of debt securities due and payable immediately. If an event of default specified in the last bullet point above occurs with respect to us, the principal amount of and accrued interest, if any, of each issue of debt securities then outstanding shall be due and payable without any notice or other action on the part of the trustee or any holder.

The holders of a majority in principal amount of the outstanding debt securities of an affected series may waive any default or event of default with respect to the series and its consequences, except defaults or events of default regarding payment of principal, premium, if any, or interest, unless we have cured the default or event of default in accordance with the indenture. Any waiver shall cure the default or event of default.

Subject to the terms of the indenture, if an event of default under an indenture shall occur and be continuing, the trustee will be under no obligation to exercise any of its rights or powers under such indenture at the request or direction of any of the holders of the applicable series of debt securities, unless such holders have offered the trustee reasonable indemnity. The holders of a majority in principal amount of the outstanding debt securities of any series will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee, or exercising any trust or power conferred on the trustee, with respect to the debt securities of that series; provided that:

• the direction so given by the holder is not in conflict with any law or the applicable indenture; and

• subject to its duties under the Trust Indenture Act, the trustee need not take any action that might involve it in personal liability or might be unduly prejudicial to the holders not involved in the proceeding.

A holder of the debt securities of any series will have the right to institute a proceeding under the indenture or to appoint a receiver or trustee, or to seek other remedies only if:

• the holder has given written notice to the trustee of a continuing event of default with respect to that series;

• the holders of at least 25% in aggregate principal amount of the outstanding debt securities of that series have made written request;

• such holders have offered to the trustee indemnity satisfactory to it against the costs, expenses and liabilities to be incurred by the trustee in compliance with the request; and

• the trustee does not institute the proceeding, and does not receive from the holders of a majority in aggregate principal amount of the outstanding debt securities of that series other conflicting directions within 90 days after the notice, request and offer.

These limitations do not apply to a suit instituted by a holder of debt securities if we default in the payment of the principal, premium, if any, or interest on, the debt securities.

We will periodically file statements with the trustee regarding our compliance with specified covenants in the indenture.

Modification of Indenture; Waiver

Unless we provide otherwise in the prospectus supplement applicable to a particular series of debt securities, we and the trustee may change an indenture without the consent of any holders with respect to specific matters:

• to cure any ambiguity, defect or inconsistency in the indenture or in the debt securities of any series;

• to comply with the provisions described above under “Description of Debt Securities - Consolidation, Merger or Sale”;

15

• to provide for uncertificated debt securities in addition to or in place of certificated debt securities;

• to add to our covenants, restrictions, conditions or provisions such new covenants, restrictions, conditions or provisions for the benefit of the holders of all or any series of debt securities, to make the occurrence, or the occurrence and the continuance, of a default in any such additional covenants, restrictions, conditions or provisions an event of default or to surrender any right or power conferred upon us in the indenture;

• to add to, delete from or revise the conditions, limitations, and restrictions on the authorized amount, terms, or purposes of issue, authentication and delivery of debt securities, as set forth in the indenture;

• to make any change that does not adversely affect the interests of any holder of debt securities of any series in any material respect;

• to provide for the issuance of and establish the form and terms and conditions of the debt securities of any series as provided above under “Description of Debt Securities - General” to establish the form of any certifications required to be furnished pursuant to the terms of the indenture or any series of debt securities, or to add to the rights of the holders of any series of debt securities;

• to evidence and provide for the acceptance of appointment under any indenture by a successor trustee; or

• to comply with any requirements of the SEC in connection with the qualification of any indenture under the Trust Indenture Act.

In addition, under the indenture, the rights of holders of a series of debt securities may be changed by us and the trustee with the written consent of the holders of at least a majority in aggregate principal amount of the outstanding debt securities of each series that is affected. However, unless we provide otherwise in the prospectus supplement applicable to a particular series of debt securities, we and the trustee may make the following changes only with the consent of each holder of any outstanding debt securities affected:

• extending the fixed maturity of any debt securities of any series;

• reducing the principal amount, reducing the rate of or extending the time of payment of interest, or reducing any premium payable upon the redemption of any series of any debt securities; or

• reducing the percentage of debt securities, the holders of which are required to consent to any amendment, supplement, modification or waiver.

Discharge

The indenture provides that we can elect to be discharged from our obligations with respect to one or more series of debt securities, except for specified obligations, including obligations to:

• provide for payment;

• register the transfer or exchange of debt securities of the series;

• replace stolen, lost or mutilated debt securities of the series;

• pay principal of and premium and interest on any debt securities of the series;

• maintain paying agencies;

• hold monies for payment in trust;

• recover excess money held by the trustee;

• compensate and indemnify the trustee; and

• appoint any successor trustee.

16

In order to exercise our rights to be discharged, we must deposit with the trustee money or government obligations sufficient to pay all the principal of, any premium, if any, and interest on, the debt securities of the series on the dates payments are due.

Form, Exchange And Transfer

We will issue the debt securities of each series only in fully registered form without coupons and, unless we provide otherwise in the applicable prospectus supplement, in denominations of $1,000 and any integral multiple thereof. The indenture provides that we may issue debt securities of a series in temporary or permanent global form and as book-entry securities that will be deposited with, or on behalf of, The Depository Trust Company, or DTC, or another depositary named by us and identified in the applicable prospectus supplement with respect to that series. To the extent the debt securities of a series are issued in global form and as book-entry, a description of terms relating to any book-entry securities will be set forth in the applicable prospectus supplement.

At the option of the holder, subject to the terms of the indenture and the limitations applicable to global securities described in the applicable prospectus supplement, the holder of the debt securities of any series can exchange the debt securities for other debt securities of the same series, in any authorized denomination and of like tenor and aggregate principal amount.

Subject to the terms of the indenture and the limitations applicable to global securities set forth in the applicable prospectus supplement, holders of the debt securities may present the debt securities for exchange or for registration of transfer, duly endorsed or with the form of transfer endorsed thereon duly executed if so required by us or the security registrar, at the office of the security registrar or at the office of any transfer agent designated by us for this purpose. Unless otherwise provided in the debt securities that the holder presents for transfer or exchange, we will impose no service charge for any registration of transfer or exchange, but we may require payment of any taxes or other governmental charges.

We will name in the applicable prospectus supplement the security registrar, and any transfer agent in addition to the security registrar, that we initially designate for any debt securities. We may at any time designate additional transfer agents or rescind the designation of any transfer agent or approve a change in the office through which any transfer agent acts, except that we will be required to maintain a transfer agent in each place of payment for the debt securities of each series.

If we elect to redeem the debt securities of any series, we will not be required to:

• issue, register the transfer of, or exchange any debt securities of that series during a period beginning at the opening of business 15 days before the day of mailing of a notice of redemption of any debt securities that may be selected for redemption and ending at the close of business on the day of the mailing; or

• register the transfer of or exchange any debt securities so selected for redemption, in whole or in part, except the unredeemed portion of any debt securities we are redeeming in part.

Information Concerning The Trustee

The trustee, other than during the occurrence and continuance of an event of default under an indenture, undertakes to perform only those duties as are specifically set forth in the applicable indenture. Upon an event of default under an indenture, the trustee must use the same degree of care as a prudent person would exercise or use in the conduct of his or her own affairs. Subject to this provision, the trustee is under no obligation to exercise any of the powers given it by the indenture at the request of any holder of debt securities unless it is offered reasonable security and indemnity against the costs, expenses and liabilities that it might incur.

17

Payment And Paying Agents

Unless we otherwise indicate in the applicable prospectus supplement, we will make payment of the interest on any debt securities on any interest payment date to the person in whose name the debt securities, or one or more predecessor securities, are registered at the close of business on the regular record date for the interest.

We will pay principal of and any premium and interest on the debt securities of a particular series at the office of the paying agents designated by us, except that unless we otherwise indicate in the applicable prospectus supplement, we will make interest payments by check that we will mail to the holder or by wire transfer to certain holders. Unless we otherwise indicate in the applicable prospectus supplement, we will designate the corporate trust office of the trustee as our sole paying agent for payments with respect to debt securities of each series. We will name in the applicable prospectus supplement any other paying agents that we initially designate for the debt securities of a particular series. We will maintain a paying agent in each place of payment for the debt securities of a particular series.

All money we pay to a paying agent or the trustee for the payment of the principal of or any premium or interest on any debt securities that remains unclaimed at the end of two years after such principal, premium or interest has become due and payable will be repaid to us, and the holder of the debt security thereafter may look only to us for payment thereof.

Governing Law

The indenture and the debt securities, and any claim, controversy or dispute arising under or related to the indenture or the debt securities, will be governed by and construed in accordance with the laws of the State of New York, except to the extent that the Trust Indenture Act of 1939 is applicable.

• through a combination of any of these methods; or

• through any other method permitted by applicable law and described in a prospectus supplement.

In addition, we may enter into derivative or hedging transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. In connection with such a transaction, the third parties may sell securities covered by and pursuant to this prospectus and any accompanying prospectus supplement. If so, the third party may use securities borrowed from us or others to settle such sales and may use securities received from us to close out any related short positions. We may also loan or pledge securities covered by this prospectus and any accompanying prospectus supplement to third parties, who may sell the loaned securities or, in an event of default in the case of a pledge, sell the pledged securities pursuant to this prospectus and any accompanying prospectus supplement.

The prospectus supplement with respect to any offering of securities will include the following information:

• the terms of the offering;

• the names of any underwriters, dealers or direct purchasers;

• the name or names of any managing underwriter or underwriters;

• the purchase price or initial public offering price of the securities;

• the net proceeds from the sale of the securities;

• any delayed delivery arrangements;

• any underwriting discounts, commissions and other items constituting underwriters’ compensation;

• any discounts or concessions allowed or reallowed or paid to dealers;

• any commissions paid to agents; and

• any securities exchange on which the securities may be listed.

Sale through Underwriters or Dealers

If underwriters are used in the sale, the underwriters will acquire the securities for their own account. 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 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. Unless we inform you otherwise in the applicable prospectus supplement, the obligations of the underwriters to purchase the securities will be subject to

23

certain conditions, and the underwriters will be obligated to purchase all of the offered securities if they purchase any of them. The underwriters may change from time to time any initial public offering price and any discounts or concessions allowed or reallowed or paid to dealers.

During and after an offering through underwriters, the underwriters may purchase and sell the securities in the open market. These transactions may include overallotment and stabilizing transactions and purchases to cover syndicate short positions created in connection with the offering. The underwriters may also impose a penalty bid, which means that selling concessions allowed to syndicate members or other broker-dealers for the offered securities sold for their account may be reclaimed by the syndicate if the offered securities are repurchased by the syndicate in stabilizing or covering transactions. These activities may stabilize, maintain or otherwise affect the market price of the offered securities, which may be higher than the price that might otherwise prevail in the open market. If commenced, the underwriters may discontinue these activities at any time.

Some or all of the securities that we offer through this prospectus may be new issues of securities with no established trading market. Any underwriters to whom we sell our securities for public offering and sale may make a market in those securities, but they will not be obligated to do so and they may discontinue any market making at any time without notice. Accordingly, we cannot assure you of the liquidity of, or continued trading markets for, any securities that we offer.

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

If agents are used in an offering, the names of the agents and the terms of the agency will be specified in a prospectus supplement. Unless otherwise indicated in a prospectus supplement, the agents will act on a best-efforts basis for the period of their appointment.

Dealers and agents named in a prospectus supplement may be underwriters as defined in the Securities Act and any discounts or commissions they receive from us and any profit on their resale of the securities may be treated as underwriting discounts and commissions under the Securities Act. We will identify in the applicable prospectus supplement any underwriters, dealers or agents and will describe their compensation. We may have agreements with the underwriters, dealers and agents to indemnify them against specified civil liabilities, including liabilities under the Securities Act.

Underwriters, dealers or agents and their associates may engage in other transactions with and perform other services for us in the ordinary course of business.

If so indicated in a prospectus supplement, we will authorize underwriters or other persons acting as our agents to solicit offers by institutional investors to purchase securities pursuant to contracts providing for payment and delivery on a future date. We may enter contracts with commercial and savings banks, insurance companies, pension funds, investment companies, educational and charitable institutions and other institutional investors. The obligations of any institutional investor will be subject to the condition that its purchase of the offered securities will not be illegal at the time of delivery. The underwriters and other agents will not be responsible for the validity or performance of contracts.

Direct Sales and Sales through Agents

We may sell the securities directly. In this case, no underwriters or agents would be involved. We may also sell the securities through agents designated by us from time to time. In the applicable prospectus supplement, we will name any agent involved in the offer or sale of the offered securities, and we will describe any commissions payable to the agent. Unless we inform you otherwise in the applicable prospectus supplement, any agent will agree to use its reasonable best efforts to solicit purchases for the period of its appointment.

24

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 will describe the terms of any sales of these securities in the applicable prospectus supplement.

At the Market Offerings

We may also sell the securities offered by any applicable prospectus supplement in “at the market offerings” 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.

Remarketing Arrangements

Securities may also be offered and sold, if so indicated in the applicable prospectus supplement, in connection with a remarketing upon their purchase, in accordance with a redemption or repayment pursuant to their terms, or otherwise, by one or more remarketing firms, acting as principals for their own accounts or as agents for us. Any remarketing firm will be identified and the terms of its agreements, if any, with us and its compensation will be described in the applicable prospectus supplement.

Delayed Delivery Contracts

If we so indicate in the applicable prospectus supplement, we may authorize agents, underwriters or dealers to solicit offers from certain types of institutions to purchase securities from us at the public offering price under delayed delivery contracts. These contracts would provide for payment and delivery on a specified date in the future.

The contracts would be subject only to those conditions described in the applicable prospectus supplement. The applicable prospectus supplement will describe the commission payable for solicitation of those contracts.

General Information

We may have agreements with the underwriters, dealers, agents and remarketing firms to indemnify them against certain civil liabilities, including liabilities under the Securities Act, or to contribute with respect to payments that the underwriters, dealers, agents or remarketing firms may be required to make. Underwriters, dealers, agents and remarketing firms may be customers of, engage in transactions with or perform services for us in the ordinary course of their businesses.

SUBJECT TO COMPLETION, DATED DECEMBER 15, 2022

PROSPECTUS SUPPLEMENT

Up to $500,000,000

Common Stock

This prospectus supplement is being filed to update, amend and supplement certain information in the prospectus supplement of CleanSpark, Inc. dated June 3, 2021 (including any documents incorporated by reference therein), or the Prior ATM Sales Prospectus. The Prior ATM Sales Prospectus will no longer be in effect as of the date of this prospectus supplement.

On June 3, 2021, we entered into an at the market offering agreement, or the sales agreement, with H.C. Wainwright & Co., LLC, or Wainwright, relating to shares of our common stock, par value $0.001 per share, offered by the Prior ATM Sales Prospectus.

On December 14, 2022, we entered into an amendment to the sales agreement, or the amendment to the sales agreement. In accordance with the terms of the sales agreement, as amended, or the amended sales agreement, under this prospectus supplement, we may now offer and sell shares of our common stock from time to time having an aggregate offering price of up to $500,000,000 through Wainwright acting as our sales agent, exclusive of any amounts previously sold under the sales agreement.

From June 2021 through December 9, 2022, the Company issued and sold 35,968,018 shares under the sales agreement for gross proceeds of $219,733,443 and net proceeds of $212,990,030, after deducting commissions to Wainwright on the shares sold and offering expenses.

Our common stock is listed on the Nasdaq Capital Market, or Nasdaq, under the symbol “CLSK.” On December 12, 2022, the last reported sale price of our common stock on Nasdaq was $2.30 per share.

Sales of our common stock, if any, under this prospectus supplement and the accompanying prospectus may be made in sales deemed to be “at the market” equity offerings as defined in Rule 415 promulgated under the Securities Act of 1933, as amended, or the Securities Act, including sales made directly on or through the Nasdaq Capital Market, the existing trading market for our common stock, sales made to or through a market maker other than on an exchange or otherwise, directly to the sales agent as principal, in negotiated transactions at market prices prevailing at the time of sale or at prices related to such prevailing market prices, and/or in any other method permitted by law. If we and Wainwright agree on any method of distribution other than sales of shares of our common stock into the Nasdaq Capital Market or another existing trading market in the United States at market prices, we will file a further prospectus supplement providing all information about such offering as required by Rule 424(b) under the Securities Act. Wainwright is not required to sell any specific number or dollar amount of shares, but will act as sales agent on a commercially reasonable efforts basis consistent with its normal trading and sales practices. There is no arrangement for funds to be received in any escrow, trust or similar arrangement.

Wainwright will be entitled to compensation at a fixed commission rate equal to 3.0% of the gross proceeds per share sold under the sales agreement. In connection with the sale of the common stock on our behalf, Wainwright may be deemed to be an “underwriter” within the meaning of the Securities Act, and the compensation of Wainwright may be deemed to be underwriting commissions or discounts. We have also agreed to provide indemnification and contribution to Wainwright with respect to certain liabilities, including liabilities under the Securities Act or the Exchange Act of 1934, as amended, or the Exchange Act.

Investing in our common stock involves a high degree of risk. Before deciding whether to invest in our common stock, please read “Risk Factors” beginning on page S-8 of this prospectus supplement, and in the accompanying prospectus and in the documents incorporated by reference in this prospectus supplement that we file with the Securities and Exchange Commission.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or passed upon the adequacy or accuracy of this prospectus supplement or the prospectus to which it relates. Any representation to the contrary is a criminal offense.

ABOUT THIS PROSPECTUS SUPPLEMENT

This prospectus supplement and the accompanying prospectus are part of a registration statement that we filed with the Securities and Exchange Commission (the “SEC”) using a “shelf” registration process. This document is in two parts. The first part is this prospectus supplement, which describes the specific terms of this offering and also supplements and updates information contained or incorporated by reference in the accompanying prospectus.

PROSPECTUS SUPPLEMENT SUMMARY

This summary highlights selected information about CleanSpark, Inc. contained elsewhere in this prospectus supplement, in the accompanying prospectus and in the documents incorporated herein by reference. This summary does not contain all of the information that may be important to you in making an investment decision. For a more complete understanding of CleanSpark, Inc., you should read carefully this entire prospectus supplement and the accompanying prospectus, including the “Risk Factors” section, and the other documents we refer to and incorporate by reference. Unless otherwise indicated, “common stock” means our common stock, par value $0.001 per share.

Overview

CleanSpark, Inc. is a leading sustainable bitcoin mining company incorporated in Nevada, whose common stock is listed on the Nasdaq Capital Market. The Company, through itself and its wholly owned subsidiaries, has operated in the digital currency mining industry since December 2020.

We are currently working with various industry participants in developing a long-term sustainability and clean energy plan for our bitcoin mining operations. As part of this plan, we are using the available clean and renewable energy resources that we currently have reasonable access to at our bitcoin mining locations in order to further support our sustainability efforts.

Through CleanSpark, Inc. and our wholly owned subsidiaries ATL Data Centers LLC (“ATL”), CleanBlok, Inc. (“CleanBlok”), CleanSpark DW, LLC, and CleanSpark GLP, LLC, we mine bitcoin. We entered the bitcoin mining industry through our acquisition of ATL in December 2020, acquired a second data center in August 2021, a third data center and mining equipment in August 2022, a fourth data center and mining equipment in October 2022, and have had a co-location agreement with New York-based Coinmint in place since July 2021. Bitcoin mining has now become our principal revenue generating business activity. We currently intend to continue to acquire additional facilities, equipment and infrastructure capacity to continue to expand our bitcoin mining operations.

In August 2022, we completed the acquisition of certain real property located in Wilkes County, Georgia, and approximately 3,400 S19 and S19j Pro series bitcoin miners capable of providing computing power of approximately 341,000 terahash per second. The property acquired provided us with a turn-key data center campus capable of supporting approximately 1 exahash per second of computing power, upon closing of the acquisition. We expect to expand the campus to support approximately 2.6 exahash per second of computing power (collectively, the “WAHA and SPRE Assets”).

In October 2022, we acquired the lease for 16.35 acres of real property located in Sandersville, Washington County, Georgia, all personal property situated on such property, and 6,349 application specific integrated circuit miners (“ASICs”) capable of providing computing power of approximately 530,000 terahash per second from subsidiaries of Mawson Infrastructure Group, Inc. (“Mawson”). The property acquired provided the Company with a turn-key data center campus capable of supporting approximately 2.4 exahash per second of computing power, upon closing of the acquisition. The company expects to expand the campus to support approximately 7.0 exahash per second of computing power (collectively, the “Mawson Assets”).

S-7

RISK FACTORS

Investing in our common stock involves a high degree of risk. Before you make an investment decision with respect to our common stock, you should consider carefully the risks described below and discussed under the section captioned “Risk Factors” contained in our Annual Report on Form 10-K for the fiscal year ended September 30, 2022, and other information included in any document that we file from time to time with the SEC after the date of this prospectus supplement that is incorporated by reference herein, as well as other information contained or incorporated by reference in this prospectus supplement or the accompanying prospectus. If any of the following events or any of the events described in any such other document actually occur, our business, operating results, prospects or financial condition could be materially and adversely affected. The risks described below are not the only ones that we face. Additional risks not presently known to us or that we currently deem immaterial may also affect our business and operations.

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

Investors that purchase shares in this offering at different times will likely pay different prices, and so may experience different outcomes in their investment results. We will have discretion, subject to market demand, to vary the timing, prices, and numbers of shares sold, and there is no minimum or maximum sales price. Investors may experience a decline in the value of their shares as a result of sales made at share prices lower than the prices they paid.

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 a sales notice to Wainwright at any time throughout the term of the sales agreement. The number of shares that are sold by Wainwright after delivering a sales notice will fluctuate based on the market price of our common stock during the sales period and limits we set with Wainwright. Because the price per share of each share sold in this offering will fluctuate based on the market price of our common stock during the sales period, it is not possible at this stage to predict the number of shares that will be ultimately issued. As of December 12, 2022, we had 15,207,809 authorized but unissued shares of Common Stock (less the number of shares of Common Stock issuable upon exercise, conversion or exchange of any outstanding securities of the Company or otherwise reserved from the Company’s authorized capital stock). Although we plan to seek shareholder approval to increase the number of authorized shares under our articles of incorporation, we are presently limited as to the number of shares we may issue pursuant to the sales agreement.

If you purchase our common stock in this offering, you may incur immediate and substantial dilution in the book value of your shares.

Investors purchasing shares of common stock in this offering may pay a price per share that substantially exceeds the as adjusted net tangible book value per share of our common stock prior to this offering. After giving effect to the sale of shares of our common stock in this offering at the assumed public offering price of $2.30 per share (which was the closing sales price of our common stock on the Nasdaq Capital Market on December 12, 2022), and after deducting commissions and estimated offering expenses, our as adjusted net tangible book value as of September 30, 2022 would have been approximately $868 million or approximately $3.18 per share. As a result, investors purchasing shares of common stock in this offering will incur immediate accretive value of $0.88 per share, representing the difference between the assumed public offering price of $2.30 per share and our as adjusted net tangible book value as of September 30, 2022 after giving effect to this offering. See the section entitled “Dilution” below for a more detailed discussion of dilution.

S-8

You will experience further dilution if we issue additional equity securities in the future.

In order to raise additional capital, we may in the future, offer additional shares of our common stock or other securities convertible into or exercisable or exchangeable for our common stock. We cannot assure you that we will be able to sell shares or other securities in any other offering at a price per share that is equal to or greater than the price per share paid by investors in this offering, and investors purchasing shares or other securities in the future could have rights superior to existing stockholders. In addition, as of September 30, 2022, approximately 12,319,706 shares of common stock that are subject to outstanding options, warrants, preferred stock, or restricted stock units reserved for future issuance under our equity incentive plans are eligible for sale in the public market to the extent permitted by the provisions of various vesting schedules and Rule 144 and Rule 701 under the Securities Act. To the extent that outstanding options or warrants are exercised, investors purchasing our common stock in this offering will experience further dilution.

Sales of a substantial number of shares of our common stock in the public market could cause our stock price to fall.

Future sales of substantial amounts of our common stock (including in this offering), or securities convertible or exchangeable into shares of our common stock, into the public market, including shares of our common stock issued upon exercise of options and warrants, or the perception that those sales could occur, could adversely affect the prevailing market price of our common stock and our ability to raise capital in the future. Additionally, the market price of our common stock could decline as a result of sales by, or the perceived possibility of sales by, our existing stockholders of shares of our common stock in the market after this offering. These sales might also make it more difficult for us to sell equity securities at a time and price that we deem appropriate.

We have broad discretion in the use of the net proceeds of this offering and may not use them effectively.

We expect to use the net proceeds from this offering for working capital, general corporate purposes and capital expenditures. Our management will have considerable discretion in the application of any such net proceeds and could spend the proceeds in ways with which you may not agree. We may not invest the proceeds of this offering effectively or in a manner that yields a favorable or any return and, consequently, this could result in financial losses that could have a material and adverse effect on our business or cause the market price of our common stock to decline.

The price of our common stock has been, and may continue to be, volatile and could fluctuate or decline significantly, regardless of our operating performance.

The market price of our common stock has been, and may continue to be, highly volatile. Given the continued uncertainty surrounding many variables that may affect our business and the industry in which we operate, our ability to foresee results for future periods is limited. This variability could affect our operating results and thereby adversely affect our stock price. Many factors that contribute to this volatility are beyond our control and may cause the market price of our common stock to change, regardless of our operating performance. Factors that could cause fluctuation in our stock price may include, among other things:

• technological innovations or new products and services by us or our competitors;

• government regulation of our products and services;

• the establishment of partnerships with other technology companies;

• intellectual property disputes;

• additions or departures of key personnel;

• sales of our common stock;

• the trading price of bitcoin;

• our ability to integrate operations, technology, products and services;

S-9

• our ability to execute our business plan;

• loss of any strategic relationship;

• industry developments;

• general economic, market and political conditions;

• current and future litigation and negative publicity;

• period-to-period fluctuations in our financial results or those of companies that are perceived to be similar to us, including financial results that are below our or such other companies’ expectations and estimates; and

• other risks, uncertainties and factors described under the caption “Risk Factors” in this prospectus supplement, and elsewhere in this prospectus supplement, the accompanying prospectus and the documents incorporated herein by reference.

Because we have limited revenues to date, if any of these or other factors materializes, our stock price may fluctuate or decline significantly.

Specifically, the trading price of our common stock has already been correlated, and, in the future, as we continue to expand our cryptocurrency mining business, may be increasingly correlated, to the trading prices of bitcoin. Bitcoin and other cryptocurrency market prices, which have historically been volatile and are impacted by a variety of factors (including those discussed below), are determined primarily using data from various exchanges, over-the-counter markets and derivative platforms. Furthermore, such prices may be subject to factors such as those that impact commodities, more so than business activities, which could be subjected to additional influence from fraudulent or illegitimate actors, real or perceived scarcity, and political, economic, regulatory or other conditions. Pricing may be the result of, and may continue to result in, speculation regarding future appreciation in the value of cryptocurrencies, or our share price, inflating and making their market prices more volatile. For example, the closing sales price of our common stock in 2022 has been as high as $13.42 on March 28, 2022 and, as of December 12, 2022, the closing sales price was $2.30.

In addition, the stock markets in general have often experienced volatility, including, most recently, in the wake of COVID-19, that has sometimes been unrelated or disproportionate to the operating performance of particular companies. These broad market fluctuations have caused, and may continue to cause, the trading price of our common stock to decline. A continuation or worsening of the levels of market disruption and volatility seen in the recent past could have an adverse effect on our ability to access capital, on our business, financial condition, results of operations, cash flow and prospects, and on the market price of our common stock. In the past, following periods of volatility in the market price of a company’s securities, securities class-action litigation has often been brought against that company. We may become involved in this type of litigation in the future. Litigation of this type may be expensive to defend and may divert our management’s attention and resources from the operation of our business.

Our outstanding shares of Series A Preferred Stock have, and, in the future, we may issue additional shares of our Series A Preferred Stock or other series of preferred stock that have, rights, preferences and privileges that may adversely affect the common stock.

We are authorized to issue 10,000,000 shares of “blank check” preferred stock, with such rights, preferences and privileges as may be determined from time-to-time by our board of directors. Our board of directors is empowered, without shareholder approval, to issue preferred stock in one or more series, and to fix for any series the dividend rights, dissolution or liquidation preferences, redemption prices, conversion rights, voting rights, and other rights, preferences and privileges for the preferred stock. As of December 12, 2022, we had designated 2,000,000 shares as Series A Preferred Stock, of which 1,750,000 shares of Series A Preferred Stock were

S-10

outstanding. Under the terms of the Certificate of Designations for our Series A Preferred Stock, holders of shares of Series A Preferred Stock are entitled to vote together with the holders of common stock on all matters submitted to stockholders, with each share of Series A Preferred Stock entitled to 45 votes. The outstanding shares of our Series A Preferred Stock represented approximately 52.5% of the voting power of our outstanding shares as of December 12, 2022. As a result, the holders of Series A Preferred Stock are able to take action without the approval of other holders of our common stock and have historically done so through action by written consent. The holders of our Series A Preferred Stock have voting control over matters requiring stockholder approval, including amending our articles of incorporation and approval of significant corporate transactions, which could make the approval of certain transactions impossible without the support of such holders. In addition, holders of Series A Preferred Stock are also entitled to quarterly dividends, payable in cash or common stock, a liquidation preference on the stated value of $0.02 per share plus any accumulated but unpaid dividends, and the right to have each share of Series A Preferred Stock redeemed for three shares of common stock in the event of a change of control.

We may in the future issue additional series of preferred stock, and depending on the rights, preferences and privileges attributable to any designated series of preferred stock, the issuance of preferred stock could further reduce the relative voting rights and powers of the common stock and the portion of our assets allocated for distribution to common stockholders in a liquidation event, and could also result in dilution in the book value per share of the common stock. The preferred stock could also be utilized, under certain circumstances, as a method for raising additional capital or discouraging, delaying or preventing a change in control of the company, to the detriment of the investors in the common stock offered hereby. We cannot assure you that we will not issue additional shares of our preferred stock.

We qualify as a smaller reporting company, and, under the smaller reporting company rules, we are subject to scaled disclosure requirements that may make it more challenging for investors to analyze our results of operations and financial prospects.

Currently, we qualify as a “smaller reporting company” as defined by Rule 12b-2 of the Exchange Act. We have elected to provide disclosure under the smaller reporting company rules and, therefore, are subject to decreased disclosure obligations in our filings with the SEC, including being required to provide only two years of audited financial statements in our annual reports. Consequently, it may be more challenging for investors to analyze our results of operations and financial prospects.

USE OF PROCEEDS

We may issue and sell shares of our common stock having an aggregate offering price of up to $500,000,000 from time to time. Because there is no minimum offering amount required as a condition of this offering, the actual total public offering amount, commissions and proceeds to us, if any, are not determinable at this time.

We expect to use the net proceeds from this offering for growth initiatives, capital expenditures, acquisitions and general corporate purposes. However, as of the date of this prospectus supplement, the Company has no arrangements, agreements or understanding in principle of any such acquisitions.

DIVIDEND POLICY

We have never declared or paid any cash dividends on our capital stock, and we do not currently intend to pay any cash dividends on our common stock for the foreseeable future. We expect to retain future earnings, if any, to fund the development and growth of our business, subject to certain preferential dividend rights held by our Series A Preferred Stockholders. Any future determination to pay dividends on our common stock will be at

S-11

the discretion of our board of directors and will depend upon, among other factors, our results of operations, financial condition, capital requirements and any contractual restrictions.

DILUTION

If you invest in shares of common stock offered by this prospectus supplement, you will experience dilution to the extent of the difference between the public offering price per share of common stock you pay in this offering and the net tangible book value per share of our common stock immediately after giving effect to this offering. Our net tangible book value as of September 30, 2022 was approximately $383 million or approximately $6.89 per share of common stock. Net tangible book value represents total tangible assets less total liabilities. Net tangible book value per share represents net tangible book value divided by the total number of shares of common stock outstanding as of September 30, 2022.

After giving effect to the assumed sale of shares of common stock in the aggregate amount of $500,000,000 in this offering at the assumed public offering price of $2.30 per share (the closing sales price of our common stock on the Nasdaq Capital Market on December 12, 2022), and after deducting the commissions and other estimated offering expenses payable by us, assuming the company has sufficient authorized shares of common stock to issue such shares at such assumed public offering price, our as adjusted net tangible book value per share of our common stock on September 30, 2022 would have been approximately $868 million or approximately $3.18 per share of common stock. This represents an immediate decrease in net tangible book value per share of our common stock of approximately $3.71 per share to existing stockholders and an immediate increase in accretive value of approximately $0.88 per share to purchasers in this offering. The following table illustrates this per-share dilution:

Assumed public offering price per share	$	2.30
Net tangible book value per share as of September 30, 2022	$	6.89
Decrease per share attributable to new investors	$	3.71
As adjusted net tangible book value per share as of September 30, 2022 after giving effect to this offering	$	3.18
Accretive value per share to new investors	$	0.88

A $1.00 increase in the assumed public offering price of $2.30 per share (the closing sales price of our common stock on the Nasdaq Capital Market on December 12, 2022), would increase the as adjusted net tangible book value after the offering by $1.01 per share and would increase the accretive value to new investors by $0.01 per share, after deducting commissions and offering expenses payable by us in connection with this offering. A $1.00 decrease in the assumed public offering price of $2.30 per share (the closing sales price of our common stock on the Nasdaq Capital Market on December 12, 2022), would decrease the as adjusted net tangible book value after the offering by $1.21 per share and would decrease the accretive value to new investors by $0.21 per share, after deducting commissions and offering expenses payable by us in connection with this offering.

The number of shares of common stock to be outstanding after this offering is based on 55,661,337 shares of common stock outstanding as of September 30, 2022, and excludes the following, in each case as of such date:

• 1,418,938 shares issuable upon the exercise of outstanding options with a weighted average exercise price of $19.11;

• 78,548 shares reserved for issuance in connection with restricted stock unit awards under our equity compensation plan;

• 5,370,000 shares reserved for issuance in connection with future restricted stock unit awards under our equity compensation plan, subject to shareholder ratification;

S-12

• 202,220 shares issuable upon the exercise of outstanding warrants with a weighted average exercise price of $13.30;

• 1,100,890 shares issuable upon to Mawson pursuant to earn-out provisions in our purchase agreement with Mawson; and

• 5,250,000 shares issuable if all of our 1,750,000 shares of Series A Preferred Stock issued and outstanding are redeemed.

To the extent that outstanding options or warrants are exercised or outstanding restricted stock units vest, investors purchasing our common stock in this offering will experience further dilution. In addition, to the extent that additional capital is raised through the sale of equity or convertible debt securities, the issuance of these securities could result in further dilution to our stockholders.

PLAN OF DISTRIBUTION

We have entered into the amended sales agreement with Wainwright under which we may issue and sell from time to time shares of our common stock having an aggregate offering price of not more than $500,000,000 through Wainwright as our sales agent. Sales of our common stock, if any, will be made by any method permitted by law deemed to be an “at the market offering” as defined in Rule 415 promulgated under the Securities Act. If we and Wainwright agree on any method of distribution other than sales of shares of our common stock on or through the Nasdaq Capital Market or another existing trading market in the United States at market prices, we will file a further prospectus supplement providing all information about such offering as required by Rule 424(b) under the Securities Act.

Wainwright will offer our common stock at prevailing market prices subject to the terms and conditions of the amended sales agreement as agreed upon by us and Wainwright. We will designate the maximum number of shares which we desire to sell on a daily basis, any minimum price below which sales may not be made and other sale parameters as we deem appropriate. Subject to the terms and conditions of the amended sales agreement, Wainwright will use its commercially reasonable efforts consistent with its normal trading and sales practices and applicable law and regulations to sell on our behalf all of the shares of common stock so designated. We or Wainwright may suspend the offering of our common stock being made through Wainwright under the amended sales agreement upon proper notice to the other party.

Settlement for sales of common stock will occur on the second business day, or such shorter settlement cycle as may be in effect under Exchange Act Rule 15c6-1 from time to time, following the date on which any sales are made, or on some other date that is agreed upon by us and Wainwright 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 and the accompanying prospectus will be settled through the facilities of The Depository Trust Company or by such other means as we and Wainwright may agree upon. There is no arrangement for funds to be received in an escrow, trust or similar arrangement.

We will pay Wainwright in cash, upon each sale of our shares of common stock pursuant to the amended sales agreement, a commission equal to 3.0% of the gross proceeds from each sale of shares of our common stock. Because there is no minimum offering amount required as a condition of this offering, the actual total public offering amount, commissions and proceeds to us, if any, are not determinable at this time. Pursuant to the terms of the amended sales agreement, we agreed to reimburse Wainwright for the documented fees and costs of its legal counsel reasonably incurred in connection with entering into the transactions contemplated by the amended sales agreement in an amount not to exceed $100,000 in the aggregate. Additionally, pursuant to the terms of the amended sales agreement, we agreed to reimburse Wainwright for the documented fees and costs of its legal counsel reasonably incurred in connection with entering into the amendment to the sales agreement and incurred in connection with Wainwright’s ongoing diligence, drafting and other filing requirements arising from the transactions contemplated by the amended sales agreement for a 24 month period following the date of the amendment to the sales agreement, in an amount not to exceed $100,000 in the aggregate. We will report at

S-13

least quarterly the number of shares of common stock sold through Wainwright under the amended sales agreement, the net proceeds to us and the compensation paid by us to Wainwright in connection with the sales of common stock.

In connection with the sales of common stock on our behalf, Wainwright may be deemed to be an “underwriter” within the meaning of the Securities Act, and the compensation paid to Wainwright may be deemed to be underwriting commissions or discounts. We have agreed in the amended sales agreement to provide indemnification and contribution to Wainwright against certain liabilities, including liabilities under the Securities Act or the Exchange Act.

The offering of our shares of common stock pursuant to the amended sales agreement will terminate upon the earlier of the (i) sale of all of our shares of common stock provided for in this prospectus supplement or (ii) termination of the amended sales agreement as permitted therein.

From time to time, Wainwright and its affiliates have provided, and may provide in the future, various advisory, investment and commercial banking and other services to us in the ordinary course of business, including in connection with offerings by us in October 2020, March 2021 and June 2021, for which it has received and may continue to receive customary fees and commissions. To the extent required by Regulation M, Wainwright will not engage in any market making activities involving our shares of common stock while the offering is ongoing under this prospectus supplement. This summary of the material provisions of the amended sales agreement does not purport to be a complete statement of its terms and conditions.

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

For a more complete understanding of CleanSpark, Inc., you should read carefully this entire prospectus, including the “Risk Factors” section, and the other documents we refer to and incorporate by reference.

Overview

CleanSpark, Inc. is a leading sustainable bitcoin mining company incorporated in Nevada, whose common stock is listed on the Nasdaq Capital Market. The Company, through itself and its wholly owned subsidiaries, has operated in the bitcoin mining industry since December 2020.

We are currently working on developing a long-term sustainability and clean energy plan for our bitcoin mining operations. As part of this plan, we are using the available clean and renewable energy resources that we currently have reasonable access to at our bitcoin mining locations in order to further support our sustainability efforts.

Through our wholly owned subsidiaries, ATL Data Centers LLC (“ATL”) and CleanBlok, Inc. (“CleanBlok”), we mine bitcoin. We entered the bitcoin mining industry through our acquisition of ATL in December 2020. We acquired a second data center in August 2021 and have had a co-location agreement with New York-based Coinmint in place since July 2021. In March 2022, we entered into a colocation agreement with Lancium LLC pursuant to which we have access to up to 500 MWs of power. Bitcoin mining has now become our principal revenue generating business activity, and consistent with our current business strategy, we intend to explore and opportunistically continue to acquire additional facilities, equipment and infrastructure capacity as well as evaluate other colocation opportunities, with the intention of expanding our bitcoin mining operations.

In line with our business strategy, on August 17, 2022, we consummated the purchase of certain assets for total consideration of $23,891,610, including cash, assumption of a real estate mortgage and a seller issued note payable. The assets acquired include 27 acres of real property and related electrical infrastructure currently providing 36 megawatts of power, with an additional 50 megawatts of capacity expected to be available in mid-2023, located in Washington, GA. The August Transaction also included mining machines with computing power of approximately 341 petahash.

On October 8, 2022, we completed the acquisition of a lease for approximately 16.35 acres of real property located in Sandersville, Washington County, Georgia (the “Property”), all personal property located on the Property and 6,349 application-specific integrated circuit miners (the “ASICs”) from subsidiaries of Mawson Infrastructure Group, Inc. a Delaware corporation (“Mawson”), who is the selling shareholder named herein (the “Mawson Transaction”), all pursuant to a Purchase and Sale Agreement dated September 8, 2022 (the “Purchase Agreement”) and an Equipment Purchase and Sale Agreement dated September 8, 2022.

We paid the following consideration to Mawson for the Property: (i) $13.5 million in cash; (ii) 1,590,175 shares (the “Closing Shares”) of our common stock, par value $0.001 per share (which had a value of approximately $4.8 million based upon the closing price of the common stock on October 7, 2022), and (iii) $6.5 million in seller financing in the form of a promissory note. We also agreed to pay up to $9.02 million in cash within 15 days of the closing for the ASICs.

The following additional consideration may be payable to Mawson following the closing:

• up to 1,100,890 shares of our common stock (the “Earn-out Shares” and, together with the Closing Shares, the “Company Shares”) (which have a value of approximately $3.3 million based upon the closing price of our common stock on October 7, 2022), based upon the number of modular data centers on the Property occupied by Mawson being emptied and made available for our use; and

• up to an additional $2.0 million in a seller-financed earn-out payable at least 60 days post-closing if we are able to utilize at least an additional 150 MW of power on the Property by the six month anniversary of the closing.

Mawson and its affiliates (collectively, the “Selling Parties”) have granted us a right of first refusal for a period of one year following the closing with respect to a Selling Party’s potential sale of certain cryptocurrency mining facilities, mining assets and properties, including any U.S. facilities in which the Selling Parties acquire an interest during the period of the right of first refusal (individually, the “Other Mining Property”). The Selling Parties have also granted us a right of first offer with respect to the Other Mining Property for a period of 180 days after the closing.

We are filing this prospectus to register the Company Shares for resale by Mawson, pursuant to the terms of the Purchase Agreement.

Information about the selling shareholder may change over time. As used in this prospectus, the term “selling shareholder” includes the selling shareholder listed below, and any donee, pledgee, transferee or other successor in interest selling shares received after the date of this prospectus from a selling shareholder as a gift, pledge, or other non-sale related transfer.

The following table sets forth the name of the selling shareholder, the number of shares of our common stock and the percentage of our common stock beneficially owned by the selling shareholder prior to this offering, the number of shares that may be offered under this prospectus by the selling shareholder, and the number of shares of our common stock and the percentage of our common stock to be beneficially owned by the selling shareholder after completion of this offering, assuming that all shares offered hereunder are sold as contemplated herein.

PLAN OF DISTRIBUTION

The selling shareholder may offer and sell, from time to time, some or all of the shares of common stock covered by this prospectus. Registration of the shares of common stock covered by this prospectus does not mean, however, that those shares necessarily will be offered or sold, or if they are, that they will be sold pursuant to this prospectus. We will not receive any proceeds from any sale by the selling shareholder of its shares of common stock. See “Use of Proceeds.” We will pay all costs, expenses and fees in connection with the registration of the shares of common stock, including fees of our counsel and accountants and fees payable to the SEC. The selling shareholder will pay all underwriting discounts and commissions and similar selling expenses, if any, attributable to the sale of the shares of common stock covered by this prospectus.

The selling shareholder may sell the shares of common stock covered by this prospectus from time to time, at market prices prevailing at the time of sale, at prices related to market prices, at a fixed price or prices subject to change or at negotiated prices, in any manner permitted by the Securities Act, including any one or more of the following ways:

• in privately negotiated transactions;

• through broker-dealers, who may act as agents or principals;

• in a block trade in which a broker-dealer will attempt to sell a block of shares of common stock as agent but may position and resell a portion of the block as principal to facilitate the transaction;

• through one or more underwriters on a firm commitment or best-efforts basis;

• directly to one or more purchasers;

• through selling agents; or

• in any combination of the above.

The selling shareholder has agreed that it will not participate in any underwritten offering with respect to the shares of common stock covered by this prospectus unless (a) we provide our prior written consent to such offering and (b) the managing underwriter and any other underwriters thereof shall be designated by us. In addition, the selling shareholder has agreed not to sell more than five percent (5%) of the average daily trading volume of our common stock (the “Average Trading Volume”) on any trading day, other than through private-block sales. The Average Trading Volume will be based upon the average trading volume of our common stock on the Nasdaq Capital Market or, if not the Nasdaq Capital Market, the principal trading market for our common stock) for the 30- day period preceding any sale of our common stock by the selling shareholder.

In effecting sales, brokers or dealers engaged by the selling shareholder may arrange for other brokers or dealers to participate. Broker-dealer transactions may include:

• purchases of the shares of common stock by a broker-dealer as principal and resales of the shares of common stock by the broker-dealer for its account pursuant to this prospectus;

• ordinary brokerage transactions; or

• transactions in which the broker-dealer solicits purchasers.

At any time a particular offer of the shares of common stock covered by this prospectus is made, a prospectus supplement, if required, will be distributed which will set forth the aggregate amount of shares of common stock covered by this prospectus being offered and the terms of the offering, including the name or names of any underwriters, dealers, brokers or agents, any option under which underwriters may purchase additional shares of common stock from the selling shareholder, any discounts, commissions, concessions and other items constituting compensation from the selling shareholder and any discounts, commissions or concessions allowed or reallowed or paid to dealers. Such prospectus supplement will be filed with the SEC to reflect the disclosure of additional information with respect to the distribution of the shares of common stock covered by this prospectus.

In connection with the sale of the shares of common stock covered by this prospectus through underwriters, underwriters may receive compensation in the form of underwriting discounts or commissions and may also receive commissions from purchasers of shares of common stock for whom they may act as agent. Underwriters may sell to or through dealers, and such dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters and/or commissions from the purchasers for whom they may act as agent.

Any underwriters, broker-dealers or agents participating in the distribution of the shares of common stock covered by this prospectus may be deemed to be “underwriters” within the meaning of the Securities Act, and any commissions received by any of those underwriters, broker-dealers or agents may be deemed to be underwriting commissions under the Securities Act. The selling shareholder may also be deemed to be an underwriter, and any discounts and commissions it receives and any profit it realizes on the sale of the common stock may be deemed to be underwriting commissions under the Securities Act.

Agents, underwriters and dealers may be entitled under agreements which may be entered into with us or the selling shareholder to indemnification by us or the selling shareholder against specified liabilities, including liabilities incurred under the Securities Act, or to contribution by us or the selling shareholder to payments it may be required to make in respect of such liabilities.

INFORMATION NOT REQUIRED IN THE PROSPECTUS

Item 14. Other Expenses of Issuance and Distribution

The following is an estimate of the expenses (all of which are to be paid by the registrant) that we may incur in connection with the securities being registered hereby.

(2) These fees are calculated based on the securities offered and the number of issuances and accordingly cannot be estimated at this time.

Item 15. Indemnification of Directors and Officers

Our officers and directors are exculpated and indemnified as provided by the Nevada Revised Statutes (“NRS”) and our articles of incorporation and bylaws, each as amended.

NRS 78.138(7) provides that, subject to limited statutory exceptions and unless the articles of incorporation or an amendment thereto (in each case filed on or after October 1, 2003) provide for greater individual liability, a director or officer is not individually liable to a 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 the presumption established by the business judgment rule codified in NRS 78.138(3) has been rebutted and it is proven that: (i) the act or failure to act constituted a breach of his or her fiduciary duties as a director or officer and (ii) the breach of those duties involved intentional misconduct, fraud or a knowing violation of law. Our articles of incorporation, as amended, provide that directors shall have no liability to the Company or its stockholders for monetary damages for conduct as a director, except for acts or omissions that involve intentional misconduct by the director, or a knowing violation of law by the director, or for conduct violating NRS 78.138(7), or for any transaction from which the director will personally receive a benefit in money, property or services to which the director is not legally entitled.

NRS 78.7502 permits a corporation to indemnify, pursuant to that statutory provision, a present or former director, officer, employee or agent of the corporation, or of another entity or enterprise for which such person is

II-1

or was serving in such capacity at the request of the corporation, who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, except an action by or in the right of the corporation, against expenses, including attorneys’ fees, judgments, fines and amounts paid in settlement actually and reasonably incurred in connection therewith, arising by reason of such person’s service in such capacity if such person (i) is not liable pursuant to NRS 78.138, or (ii) acted in good faith and in a manner which he or she reasonably believed to be in or not opposed to the best interests of the corporation and, with respect to a criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful. In the case of actions brought by or in the right of the corporation, however, no indemnification pursuant to NRS 78.7502 may be made for any claim, issue or matter as to which such person has been adjudged by a court of competent jurisdiction, after exhaustion of all appeals therefrom, to be liable to the corporation or for amounts paid in settlement to the corporation, unless and only to the extent that the court in which the action or suit was brought or other court of competent jurisdiction determines upon application that in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses as the court deems proper. Any discretionary indemnification pursuant to NRS 78.7502, unless ordered by a court or advanced to a director or officer by the corporation in accordance with the Nevada Revised Statutes, may be made by a corporation only as authorized in each specific case upon a determination that indemnification of the director, officer, employee or agent is proper in the circumstances. Such determination must be made (1) by the stockholders, (2) by the board of directors by majority vote of a quorum consisting of directors who were not parties to the action, suit or proceeding, (3) if a majority vote of a quorum consisting of directors who were not parties to the action, suit or proceeding so orders, by independent legal counsel in a written opinion, or (4) if a quorum consisting of directors who were not parties to the action, suit or proceeding cannot be obtained, by independent legal counsel in a written opinion. NRS 78.751 further provides that indemnification pursuant to NRS 78.7502 does not exclude any other rights to which a person seeking indemnification or advancement of expenses may be entitled under our articles of incorporation, as amended, or any bylaw, agreement, vote of stockholders or disinterested directors or otherwise, for either an action in the person’s official capacity or an action in another capacity while holding office, except that indemnification, unless ordered by a court pursuant to NRS 78.7502 or for the advancement of expenses, may not be made to or on behalf of any director or officer finally adjudged by a court of competent jurisdiction, after exhaustion of any appeals, to be liable for intentional misconduct, fraud or a knowing violation of law, and such misconduct, fraud or violation was material to the cause of action. Our articles of incorporation and bylaws, each as amended, provide for indemnification substantially similar to that provided under the statutory indemnification mechanisms provided under NRS 78.7502.

We maintain a general liability insurance policy that covers certain liabilities of directors and officers of our corporation arising out of claims based on acts or omissions in their capacities as directors or officers.

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

In any underwriting agreement we enter into in connection with the sale of common stock being registered hereby, the underwriters will agree to indemnify, under certain conditions, us, our directors, our officers and persons who control us within the meaning of the Securities Act, against certain liabilities.

Item 16. Exhibits

The Exhibits to this registration statement are listed below, under the Exhibit Index.

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;

(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 SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 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) above 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 SEC by the registrant pursuant to Section 13 or Section 15(d) of 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 a 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:

(A) 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

(B) 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 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.

II-3

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

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

(7) 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. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

(8) 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 SEC under Section 305(b)(2) of the Trust Indenture Act.
