TABLE OF CONTENTS

SELLING STOCKHOLDER

This prospectus supplement relates to the offer and sale from time to time of up to an aggregate 1,727,764 shares of our common stock by the stockholder identified in the table below, who we refer to in this prospectus supplement as the “selling stockholder,” and their transferees, pledgees, donees, assignees or other successors (each also a selling stockholder for purposes of this prospectus supplement). The selling stockholder identified below may currently hold or acquire at any time shares of our common stock in addition to those registered hereby.

We are registering 1,727,764 shares of our common stock for sale by the selling stockholder named below pursuant to the Moser Registration Rights Agreement and the Moser Purchase Agreement.

Pursuant to the Moser Purchase Agreement, the Company acquired 100% of the authorized, issued and outstanding equity ownership interests in Moser Acquisition, Inc., a Delaware corporation (“Moser AcquisitionCo”), and Moser Engine Service, Inc. (d/b/a Moser Energy Systems), a Wyoming corporation and a wholly-owned subsidiary of Moser AcquisitionCo (the “Moser Acquisition”), in exchange for (i) $180,000,000 in cash and (ii) 1,727,764 shares of common stock (the “Stock Consideration”). The Stock Consideration includes 86,388 shares of common stock subject to forfeiture for potential purchase price adjustments (the “Purchase Price Adjustment Stock Consideration”) and 23,757 shares of common stock subject to forfeiture to satisfy potential indemnification claims (the “Indemnity Stock”). The selling stockholder agreed not to transfer any of the Stock Consideration until May 25, 2025, subject to certain exceptions. Further, the lock-up provisions prevent the transfer of the Purchase Price Adjustment Stock Consideration until the final determination of the adjusted purchase price following the procedures set out in the Moser Purchase Agreement and the Indemnity Shares until February 24, 2026, in each case subject to certain exceptions.

The percent of beneficial ownership for the selling stockholder is based on 123,636,913 shares of our common stock outstanding as of May 21, 2025. Beneficial ownership is determined in accordance with the rules of the SEC. These rules generally attribute beneficial ownership of securities to persons who possess sole or shared voting or dispositive power with respect to such securities.

The table below was prepared based on information provided by or on behalf of the selling stockholder and we have not sought to verify such information. Except as disclosed elsewhere in this prospectus supplement, the accompanying base prospectus or the documents incorporated by reference herein, the selling stockholder does not have, and within the past three years has not had, any material relationship with us or any of our affiliates. Information concerning the selling stockholder may change from time to time and any changed information will be set forth in supplements to this prospectus supplement and accompanying base prospectus, if and when necessary. We will supplement or amend this prospectus supplement and accompanying base prospectus if applicable to include additional selling stockholders upon provision of all required information to us and subject to the terms of any relevant agreement between us and the selling stockholder.

The selling stockholder is not obligated to sell any of the shares of our common stock offered by this prospectus supplement. Because the selling stockholder identified in the table below may sell some or all of the shares of our common stock owned by it that are included in this prospectus supplement, and because there are currently no agreements, arrangements or understandings with respect to the sale of any of such shares of our common stock, no estimate can be given as to the number of shares of our common stock covered by this prospectus supplement that will be held by the selling stockholder upon termination of this offering. In addition, the selling stockholder may sell, transfer or otherwise dispose of, at any time and from time to time, shares of our common stock they hold in transactions exempt from the registration requirements of the Securities Act of 1933, as amended (the “Securities Act”), including pursuant to Rule 144 under the Securities Act (when available), after the date on which the selling stockholder provided the information set forth in the table below. Accordingly, the table below assumes that the selling stockholder disposes of all shares of common stock covered by this prospectus supplement and does not acquire beneficial ownership of any additional shares of common stock.

Pursuant to the Moser Registration Rights Agreement, we will bear all fees and expenses incident to our obligation to register the shares of our common stock held by the selling stockholder.

A selling stockholder, or agents designated by it, may directly solicit, from time to time, offers to purchase the shares.

To the extent required, any agents involved in the offer or sale of the shares and any commissions payable by a selling stockholder to these agents will be named and described in any applicable prospectus supplement. The agents may also be our customers or may engage in transactions with or perform services for us in the ordinary course of business.

If any selling stockholder utilizes a dealer in the sale of the shares in respect of which this prospectus supplement is delivered, the selling stockholder will sell those shares to the dealer, as principal. The dealer may then resell those shares to the public at varying prices to be determined by the dealer at the time of resale. The dealers may also be our or the selling stockholder’s customers or may engage in transactions with or perform services for us or the selling stockholder in the ordinary course of business.

S-11

TABLE OF CONTENTS

Offers to purchase shares may be solicited directly by any selling stockholder and the sale thereof may be made by any selling stockholder directly to institutional investors or others, who may be deemed to be underwriters within the meaning of the Securities Act, with respect to any resale thereof.

We or any selling stockholder may agree to indemnify underwriters, dealers and agents who participate in the distribution of securities against certain liabilities to which they may become subject in connection with the sale of the shares, including liabilities arising under the Securities Act.

A selling stockholder may offer our shares into an existing trading market in accordance with Rule 415(a)(4) under the Securities Act and on the terms described in the prospectus supplement relating thereto. Underwriters, dealers, and agents who participate in any at-the-market offerings will be described in the prospectus supplement relating thereto.

In connection with the sale of our common stock or interests therein, a selling stockholder may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the common stock in the course of hedging the positions they assume. A selling stockholder may also sell shares of our common stock short and deliver these securities to close out their short positions, or loan or pledge the common stock to broker-dealers that in turn may sell these securities. In addition, a selling stockholder may enter into derivative transactions with third parties, or sell shares not covered by this prospectus supplement to third parties in privately negotiated transactions. In connection with those derivatives, the third parties may sell shares covered by this prospectus supplement, including in short sale transactions. If so, the third party may use shares pledged by the selling stockholder or borrowed from the selling stockholder or others to settle those sales or to close out any related open borrowings of stock, and may use securities received from us in settlement of those derivatives to close out any related open borrowings of stock. The third party in such sale transactions may be deemed to be an underwriter and, if not identified in this prospectus supplement, will be named in the applicable prospectus supplement (or a post-effective amendment), to the extent required.

In addition, a selling stockholder may otherwise loan or pledge shares to a financial institution or other third party that in turn may sell the shares short using this prospectus supplement and accompanying base prospectus. Such financial institution or other third party may transfer its economic short position to investors in our shares or in connection with a concurrent offering of other securities.

The specific terms of any lock-up provisions in respect of any given offering will be described in any applicable prospectus supplement.

The underwriters, dealers and agents may engage in transactions with us or the selling stockholder, or perform services for us or the selling stockholder, in the ordinary course of business for which they receive compensation.

There can be no assurance that the selling stockholder will sell any or all of the shares of our common stock registered pursuant to the registration statement, of which this prospectus supplement and accompanying base prospectus form a part.

To the extent required, this prospectus supplement may be amended or supplemented from time to time to describe a specific plan of distribution. If required, we may add transferees, successors and donees by prospectus supplement in instances where the transferee, successor or donee has acquired its shares from holders named in this prospectus supplement after the effective date of this prospectus supplement. Transferees, successors and donees of the selling stockholder may not be able to use this prospectus for resales until they are named in the selling stockholder table by prospectus supplement or post-effective amendment.

ABOUT ATLAS ENERGY SOLUTIONS INC.

Overview

Atlas Energy Solutions Inc. (referred to herein as “Atlas,” the “Company,” “we,” “us,” “our” and like expressions) is a leading proppant producer and proppant logistics provider, serving primarily the Permian Basin of West Texas and New Mexico. We operate 12 proppant production facilities across the Permian Basin with a combined annual production capacity of 28 million tons, including both large-scale in-basin facilities and smaller distributed mining units. We manage a portfolio of leading-edge logistics assets, which includes our 42-mile Dune Express conveyor system, which is currently under construction and is scheduled to come online in the fourth quarter of 2024. In addition to our conveyor infrastructure, we manage a fleet of 120 trucks, which are capable of delivering expanded payloads due to our custom-manufactured trailers and patented drop-depot process. Our approach to managing both our proppant production and proppant logistics operations is intently focused on leveraging technology, automation and remote operations to drive efficiencies.

We are a low-cost producer of various high-quality, locally sourced proppants used during the well completion process. We offer both dry and damp sand, and carry various mesh sizes including 100 mesh and 40/70 mesh. Proppant is a key component necessary to facilitate the recovery of hydrocarbons from oil and natural gas wells.

Our logistics platform is designed to increase the efficiency, safety and sustainability of the oil and natural gas industry within the Permian Basin. Proppant logistics is increasingly a differentiating factor affecting customer choice among proppant producers. The cost of delivering sand, even short distances, can be a significant component of customer spending on their well completions given the substantial volumes that are utilized in modern well designs.

We continue to invest in and pursue leading-edge technologies, including autonomous trucking, digital infrastructure, and artificial intelligence, to support opportunities to gain efficiencies in our operations. To this end, we have recently taken delivery of next-generation dredge mining assets to drive efficiencies in our proppant production operations. These technology-focused investments aim to improve our cost structure and also combine to produce beneficial environmental and community impacts.

While our core business is fundamentally aligned with a lower emissions economy, our core obligation has been, and will always be, to our stockholders. We recognize that maximizing value for our stockholders requires that we optimize the outcomes for our broader stakeholders, including our employees and the communities in which we operate. We are proud of the fact that our approach to innovation in the hydrocarbon industry while operating in an environmentally responsible manner creates immense value. Since our founding in 2017, our core mission has been to improve human beings’ access to the hydrocarbons that power our lives while also delivering differentiated social and environmental progress. Our Atlas team has driven innovation and has produced industry-leading environmental benefits by reducing energy consumption, emissions, and our aerial footprint. We call this Sustainable Environmental and Social Progress.

We were founded in 2017 by Ben M. “Bud” Brigham, our Executive Chairman, and are led by an entrepreneurial team with a history of constructive disruption bringing significant and complementary experience to this enterprise, including the perspective of longtime E&P operators, which provides for an elevated understanding of the end users of our products and services. Our executive management team has a proven track record with a history of generating positive returns and value creation. Our experience as E&P operators was instrumental to our understanding of the opportunity created by in-basin sand production and supply in the Permian Basin, which we view as North America’s premier shale resource and which we believe will remain its most active through economic cycles.

Our Corporate Information

Atlas is a publicly listed company and trades on the New York Stock Exchange (the “NYSE”) under the ticker symbol “AESI.”

TABLE OF CONTENTS

DESCRIPTION OF CAPITAL STOCK

Atlas is incorporated in the State of Delaware. The rights of stockholders of Atlas are generally governed by Delaware law, as well as Atlas’s Amended and Restated Certificate of Incorporation (the “Charter”) and Amended and Restated Bylaws (the “Bylaws”). The following description of Atlas’s common stock, par value $0.01 per share (the “Common Stock”), and Atlas’s preferred stock, par value $0.01 per share (the “Preferred Stock”), is a summary and is qualified in its entirety by reference to the Charter and Bylaws.

General

Atlas’s authorized capital stock consists of 2,000,000,000 shares of stock, comprising: 1,500,000,000 shares of Common Stock and 500,000,000 shares of Preferred Stock. Unless Atlas’s board of directors (the “Board”) determines otherwise, Atlas issues all shares of its capital stock in uncertificated form.

Common Stock

Voting Rights

Holders of shares of Common Stock are entitled to one vote per share held of record on all matters to be voted upon by the stockholders. The holders of Common Stock do not have cumulative voting rights in the election of directors.

Dividend Rights

Holders of Common Stock are entitled to ratably receive dividends when and if declared by the Board out of funds legally available for that purpose, subject to any statutory or contractual restrictions on the payment of dividends and to any prior rights and preferences that may be applicable to any outstanding Preferred Stock.

Liquidation Rights

Upon Atlas’s liquidation, dissolution, distribution of assets or other winding up, the holders of Common Stock are entitled to receive ratably the assets available for distribution to the stockholders after payment of liabilities and the liquidation preference of any outstanding shares of Preferred Stock.

Other Matters

The shares of Common Stock have no preemptive or conversion rights and are not subject to further calls or assessment by Atlas. There are no redemption or sinking fund provisions applicable to the Common Stock. All outstanding shares of Common Stock are fully paid and non-assessable.

Preferred Stock

The Charter authorizes the Board, subject to any limitations prescribed by law, without further stockholder approval, to establish and issue from time to time one or more classes or series of Preferred Stock covering up to an aggregate of 500,000,000 shares. Each class or series of Preferred Stock will cover the number of shares and will have the powers, preferences, rights, qualifications, limitations and restrictions determined by the Board, which may include, among others, dividend rights, liquidation preferences, voting rights, conversion rights, preemptive rights and redemption rights. Except as provided by law or in a preferred stock designation, the holders of Preferred Stock will not be entitled to vote at or receive notice of any meeting of stockholders.

Anti-Takeover Effects of Provisions of Delaware Law and Atlas’s Organizational Documents

Charter and Bylaws

Provisions of the Charter and Bylaws may delay or discourage transactions involving an actual or potential change in control or change in Atlas’s management, including transactions in which stockholders

TABLE OF CONTENTS

might otherwise receive a premium for their shares or transactions that Atlas stockholders might otherwise deem to be in their best interests.

Among other things, the Charter and Bylaws have:

•

established advance notice procedures regarding stockholder proposals relating to the nomination of candidates for election as directors or new business to be brought before meetings of the stockholders. These procedures provide that notice of stockholder proposals must be timely given in writing to Atlas’s corporate secretary prior to the meeting at which the action is to be taken. Generally, to be timely, notice must be received at Atlas’s principal executive offices not less than 90 days nor more than 120 days prior to the first anniversary date of the annual meeting for the preceding year. The Bylaws specify the requirements as to form and content of all stockholders’ notices. These requirements may preclude stockholders from bringing matters before the stockholders at an annual or special meeting.

•

provided the Board the ability to authorize undesignated preferred stock. This ability makes it possible for the Board to issue, without stockholder approval, preferred stock with voting or other rights or preferences that could impede the success of any attempt to change control of Atlas. These and other provisions may have the effect of deterring hostile takeovers or delaying changes in control or management of Atlas.

•

provided that subject to the rights of the holders of any series of preferred stock to elect directors under specified circumstances and the terms of the Amended and Restated Stockholders’ Agreement, dated October 2, 2023, by and between Atlas, AESI Holdings Inc., a Delaware corporation (f/k/a Atlas Energy Solutions Inc.) (“Old Atlas”), and the parties signatory thereto (the “A&R Stockholders’ Agreement”), the authorized number of directors may be changed only by resolution of the Board.

•

provided that all vacancies, including newly created directorships, may, except as otherwise required by law or, if applicable, the rights of holders of a series of preferred stock, and subject to the terms of the A&R Stockholders’ Agreement, be filled by the affirmative vote of a majority of directors then in office, even if such directors constitute less than a quorum.

•

provided that, subject to the terms of the A&R Stockholders’ Agreement, the Bylaws can be amended or repealed at any regular or special meeting of stockholders or by the Board.

•

provided that any action required or permitted to be taken by the stockholders must be effected at a duly called annual or special meeting of stockholders and may not be effected by any consent in writing in lieu of a meeting of such stockholders, subject to the rights of the holders of any series of preferred stock with respect to such series.

•

provided that, subject to the terms of the A&R Stockholders’ Agreement, each of the Charter and Bylaws may be amended by the affirmative vote of the holders of at least two-thirds of then-outstanding common stock.

•

provided that special meetings of our stockholders may only be called by the Board (pursuant to a resolution adopted by a majority of the Board), the chief executive officer or the chairman of the Board.

•

provided for the Board to be divided into three classes of directors, with each class as nearly equal in number as possible, serving staggered three-year terms, other than directors that may be elected by holders of preferred stock, if any. This system of electing and removing directors may tend to discourage a third party from making a tender offer or otherwise attempting to obtain control of Atlas because it generally makes it more difficult for stockholders to replace a majority of the directors.

•

provided that, subject to the terms of the A&R Stockholders’ Agreement, the affirmative vote of the holders of at least 662∕3% of the voting power of all then-outstanding Atlas capital stock entitled to vote generally in the election of directors, voting together as a single class, shall be required to remove any or all of the directors from office and such removal may only be for cause.

Authorized but Unissued Capital Stock

The Delaware General Corporation Law (the “DGCL”) does not require stockholder approval for any issuance of authorized shares. However, the listing requirements of the NYSE, which will apply so long as

TABLE OF CONTENTS

the common stock remains listed on the NYSE, require stockholder approval of certain issuances equal to or exceeding 20% of the then-outstanding voting power or then-outstanding number of shares of common stock. These additional shares may be used for a variety of corporate purposes, including future public offerings, to raise additional capital or to facilitate acquisitions.

One of the effects of the existence of unissued and unreserved common stock or preferred stock may be to enable the Board to issue shares to persons friendly to current management, which issuance could render more difficult or discourage an attempt to obtain control of Atlas by means of a merger, tender offer, proxy contest or otherwise, and thereby protect the continuity of management and possibly deprive the stockholders of Atlas of opportunities to sell their shares of common stock at prices higher than prevailing market prices.

Anti-Takeover Provisions under Section 203 of the Delaware General Corporation Law

Section 203 of the DGCL (“Section 203”), subject to certain exceptions set forth therein, prohibits a Delaware corporation from engaging in any business combination (as defined in Section 203) with any interested stockholder (as defined in Section 203) for a period of three years following the date that the stockholder became an interested stockholder, unless:

•

the business combination or the transaction that resulted in the stockholder becoming an interested stockholder is approved by the board of directors before the date the interested stockholder attained that status;

•

upon consummation of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced; or

•

on or after such time the business combination is approved by the board of directors and authorized at a meeting of stockholders by at least two thirds of the outstanding voting stock that is not owned by the interested stockholder.

A corporation may elect not to be subject to Section 203. Under the Charter, Atlas has elected not to be governed by or subject to the provisions of Section 203.

Designation Rights

Among other things, the A&R Stockholders’ Agreement provides the right to designate nominees for election to the Board as follows:

•

so long as the Principal Stockholders (as defined in the A&R Stockholders’ Agreement) collectively beneficially own greater than 50% of the common stock, Ben M. Brigham, the Company’s Executive Chairman, or his affiliates will have the right to determine the size of the Board and designate all members of the Board, including the right to designate all individuals to be included in the slate of directors to be nominated by the Board for election by the stockholders of Atlas;

•

so long as the Principal Stockholders collectively beneficially own at least 35% but not greater than 50% of the common stock, Mr. Brigham or his affiliates will have the right to designate four members of the Board, including the right to designate four individuals to be included in the slate of directors to be nominated by the Board for election by the stockholders of Atlas;

•

so long as the Principal Stockholders collectively beneficially own at least 25% but not greater than 35% of the common stock, Mr. Brigham or his affiliates will have the right to designate three members of the Board, including the right to designate three individuals to be included in the slate of directors to be nominated by the Board for election by the stockholders of Atlas;

•

so long as the Principal Stockholders collectively beneficially own at least 10% but not greater than 25% of the common stock, Mr. Brigham or his affiliates will have the right to designate two members of the Board, including the right to designate two individuals to be included in the slate of directors to be nominated by the Board for election by the stockholders of Atlas; and

•

so long as the Principal Stockholders collectively beneficially own at least 5% but not greater than 10% of the common stock, Mr. Brigham or his affiliates will have the right to designate one member

TABLE OF CONTENTS

of the Board, including the right to designate one individual to be included in the slate of directors to be nominated by the Board for election by the stockholders of Atlas.

Additionally, each of the Principal Stockholders will agree to cause its respective shares of common stock to be voted in favor of the election of each of the nominees designated by Mr. Brigham or his affiliates. These provisions may have the effect of deferring, delaying or discouraging hostile takeovers, or changes in control of us or our management.

Corporate Opportunity

Under the Charter, to the extent permitted by law:

•

the Principal Stockholders and their affiliates, and any member of the Board that is not also an officer of Atlas, have the right to, and have no duty to abstain from exercising such right to, conduct business with any business that is competitive or in the same line of business as we are, do business with any of our clients or customers, or invest or own any interest publicly or privately in, or develop a business relationship with, any business that is competitive or in the same line of business as we are;

•

if the Principal Stockholders or their affiliates, or any member of the Board that is not also an officer of Atlas, acquire knowledge of a potential transaction that could be a corporate opportunity, they have no duty to offer such corporate opportunity to us; and

•

Atlas has renounced any interest or expectancy in, or in being offered an opportunity to participate in, such corporate opportunities.

Forum Selection

The Charter provides that unless Atlas consents in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware (or, if the Court of Chancery of the State of Delaware does not have jurisdiction, the Superior Court of the State of Delaware, or, if the Superior Court of the State of Delaware does not have jurisdiction, the United States District Court for the District of Delaware, in each case, subject to that court having personal jurisdiction over the indispensable parties named defendants therein) will, to the fullest extent permitted by applicable law, be the sole and exclusive forum for any stockholder (including a beneficial owner) to bring:

•

any derivative action or proceeding brought on Atlas’s behalf;

•

any action asserting a claim for a breach of a fiduciary duty owed by any of Atlas’s directors, officers, employees or stockholders to Atlas or its stockholders;

•

any action asserting a claim arising pursuant to any provision of the DGCL, the Charter or the Bylaws (as either may be amended or restated), or as to which the DGCL confers jurisdiction to the Court of Chancery of the State of Delaware, the Charter or Bylaws; or

•

any other action asserting a claim against Atlas that is governed by the internal affairs doctrine.

The Charter also provides that, unless Atlas consents in writing to an alternate forum, to the fullest extent permitted by applicable law, the federal district courts of the United States will be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act. Notwithstanding the foregoing, the exclusive forum provision will not apply to suits brought to enforce any liability or duty created by the Exchange Act or any other claim for which the federal courts have exclusive jurisdiction. While the Delaware courts have determined that such choice of forum provisions are facially valid, a stockholder may nevertheless seek to bring a claim in a venue other than those designated in the exclusive-forum provisions, and there can be no assurance that such provisions will be enforced by a court in those other jurisdictions. If a court were to find the exclusive-forum provisions contained in the Charter to be inapplicable or unenforceable in an action, Atlas may incur additional costs associated with resolving such action in other jurisdictions, which could harm our business.

Limitation of Liability and Indemnification Matters

The Charter limits the liability of Atlas’s directors for monetary damages for breach of their fiduciary duty as directors, except for liability that cannot be eliminated under the DGCL. Delaware law provides

TABLE OF CONTENTS

that directors of a company will not be personally liable for monetary damages for breach of their fiduciary duty as directors, except for liabilities:

•

for any breach of their duty of loyalty to Atlas or its stockholders;

•

for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law;

•

for unlawful payment of dividend or unlawful stock repurchase or redemption, as provided under Section 174 of the DGCL; or

•

for any transaction from which the director derived an improper personal benefit.

Any amendment, repeal or modification of these provisions will be prospective only and would not affect any limitation on liability of a director for acts or omissions that occurred prior to any such amendment, repeal or modification.

The Bylaws also permit us to purchase insurance on behalf of any officer, director, employee or other agent for any liability arising out of that person’s actions as Atlas’s officer, director, employee or agent, regardless of whether Delaware law would permit indemnification.

DESCRIPTION OF DEPOSITARY SHARES

We may offer depositary shares (either separately or together with other securities) representing fractional interests in our Preferred Stock of any series. In connection with the issuance of any depositary shares, we will enter into a deposit agreement with a bank or trust company, as depositary, which will be named in the applicable prospectus supplement. Depositary shares will be evidenced by depositary receipts issued pursuant to the related deposit agreement. Immediately following our issuance of the Preferred Stock related to the depositary shares, we will deposit the Preferred Stock with the relevant preferred stock depositary and will cause the preferred stock depositary to issue, on our behalf, the related depositary receipts. Subject to the terms of the deposit agreement, each owner of a depositary receipt will be entitled, in proportion to the fraction of a share of Preferred Stock represented by the related depositary share, to all the rights, preferences and privileges of, and will be subject to all of the limitations and restrictions on, the preferred stock represented by the depositary receipt (including, if applicable, dividend, voting, conversion, exchange redemption and liquidation rights).

TABLE OF CONTENTS

DESCRIPTION OF WARRANTS

We may issue warrants for the purchase of our Common Stock, Preferred Stock or any combination thereof. Warrants may be issued independently or together with our securities offered by any prospectus supplement and may be attached to or separate from any such offered securities. Each series of warrants will be issued under a separate warrant agreement to be entered into between us and a bank or trust company, as warrant agent, all as set forth in the prospectus supplement relating to the particular issue of warrants. The warrant agent will act solely as our agent in connection with the warrants and will not assume any obligation or relationship of agency or trust for or with any holders of warrants or beneficial owners of warrants. The following summary of certain provisions of the warrants does not purport to be complete and is subject to, and is qualified in its entirety by reference to, all provisions of the warrant agreements.

You should refer to the prospectus supplement relating to a particular issue of warrants for the terms of and information relating to the warrants, including, where applicable:

(1)

the number of securities purchasable upon exercise of the warrants and the price at which such securities may be purchased upon exercise of the warrants;

(2)

the date on which the right to exercise the warrants commences and the date on which such right expires (the “Expiration Date”);

(3)

the United States federal income tax consequences applicable to the warrants;

(4)

the amount of the warrants outstanding as of the most recent practicable date; and

(5)

any other terms of the warrants.

Warrants will be offered and exercisable for United States dollars only. Warrants will be issued in registered form only. Each warrant will entitle its holder to purchase such number of securities at such exercise price as is in each case set forth in, or calculable from, the prospectus supplement relating to the warrants. The exercise price may be subject to adjustment upon the occurrence of events described in such prospectus supplement. After the close of business on the Expiration Date (or such later date to which we may extend such Expiration Date), unexercised warrants will become void. The place or places where, and the manner in which, warrants may be exercised will be specified in the prospectus supplement relating to such warrants.

Prior to the exercise of any warrants, holders of the warrants will not have any of the rights of holders of securities, including the right to receive payments of any dividends on the securities purchasable upon exercise of the warrants, or to exercise any applicable right to vote.

We may also sell our shares of common stock under Rule 144 under the Securities Act, if available, or pursuant to other available exemptions from the registration requirements under the Securities Act, rather than under this prospectus.

We may prepare prospectus supplements for secondary offerings that will disclose the terms of the offering, including the name or names of any underwriters, dealers or agents, the purchase price of the shares, any underwriting discounts and other items constituting compensation to underwriters, dealers or agents. Shares covered by this prospectus may be sold in one or more transactions at a fixed price or prices, which may be changed, or at:

•

market prices prevailing at the time of any sale under this registration statement;

•

prices related to market prices; or

•

negotiated prices.

An agent may directly solicit, from time to time, offers to purchase the shares. Any such agent may be deemed to be an “underwriter” as that term is defined in the Securities Act. Any agents involved in the offer or sale of the shares and any commissions payable by us to these agents will be named and described in any applicable prospectus supplement. The agents may also be our customers or may engage in transactions with or perform services for us in the ordinary course of business.

If we utilize any underwriters in the sale of shares in respect of which this prospectus is delivered, we will enter into an underwriting agreement with those underwriters at the time of sale to them. We will set forth the names of these underwriters and the terms of the transaction in the prospectus supplement, which will be used by the underwriters to make resales of the shares in respect of which this prospectus is delivered to the public. The underwriters may also be our customers or may engage in transactions with or perform services for us in the ordinary course of business.

If we utilize a dealer in the sale of the shares in respect of which this prospectus is delivered, we will sell those shares to the dealer, as principal. The dealer may then resell those shares to the public at varying prices

to be determined by the dealer at the time of resale. The dealers may also be our customers or may engage in transactions with or perform services for us in the ordinary course of business.

We may agree to indemnify underwriters, dealers and agents who participate in the distribution of securities against certain liabilities to which they may become subject in connection with the sale of the shares, including liabilities arising under the Securities Act.

We may offer our shares into an existing trading market in accordance with Rule 415(a)(4) under the Securities Act and on the terms described in the prospectus supplement relating thereto. Underwriters, dealers, and agents who participate in any at-the-market offerings will be described in the prospectus supplement relating thereto.

In addition, we may enter into derivative transactions with third parties, or sell shares not covered by this prospectus to third parties in privately negotiated transactions. If the applicable prospectus supplement so indicates, in connection with those derivatives, the third parties may sell shares covered by this prospectus and the applicable prospectus supplement, including in short sale transactions. If so, we may use shares pledged by us or borrowed from us or others to settle those sales or to close out any related open borrowings of stock, and may use securities received from us in settlement of those derivatives to close out any related open borrowings of stock. The third party in such sale transactions will be an underwriter and, if not identified in this prospectus, will be named in the applicable prospectus supplement (or a post-effective amendment).

In addition, we may otherwise loan or pledge shares to a financial institution or other third party that in turn may sell the shares short using this prospectus and an applicable prospectus supplement. Such financial institution or other third party may transfer its economic short position to investors in our shares or in connection with a concurrent offering of other securities.

The specific terms of any lock-up provisions in respect of any given offering will be described in any applicable prospectus supplement.

The underwriters, dealers and agents may engage in transactions with us, or perform services for us, in the ordinary course of business for which they receive compensation.

To the extent required, this prospectus may be amended or supplemented from time to time to describe a specific plan of distribution.
