The Company

Corporate History and Background

We were originally incorporated in Delaware on July 21, 2020 under the name “Tailwind Acquisition Corp.” as a special purpose acquisition company, formed for the purpose of effecting an initial business combination with one or more target businesses. On September 9, 2020, we consummated our initial public offering. On January 31, 2023, we consummated a business combination with Nuburu Subsidiary, Inc. f/k/a Nuburu, Inc. (“Legacy Nuburu”), a privately held operating company which merged into our subsidiary Compass Merger Sub, Inc. (the “Business Combination”) and changed our name to “Nuburu, Inc.,” and we became the owner, directly or indirectly, of all of the equity interests of Nuburu Subsidiary, Inc. and its subsidiaries. Unless the context requires otherwise, references to “Nuburu,” “we,” “us,” or “our” in this section are to the business and operations of Legacy Nuburu prior to the Business Combination and to Nuburu, Inc. (the “Company”) and its subsidiaries following the Business Combination.

During 2024, our focus was on developing and delivering high-power, high-brightness blue laser technology with a broad range of high value applications that included welding and 3D printing. In 2024, we had approximately 220 granted and pending patents and patent applications globally, which included: blue laser applications such as welding, blue laser technologies, single mode blue laser technology, blue Raman laser technologies, addressable array technologies, and 3D printing using blue lasers. We shipped blue laser systems for applications including EV batteries, medical device production, large screen displays, and cell phone components. In the fourth quarter of 2024, our senior secured lenders provided notice of default with respect to our outstanding secured indebtedness and initiated a foreclosure process with respect to our patent portfolio that served as collateral for our outstanding secured indebtedness (the “Foreclosure”). In the first quarter of 2025, such secured lenders completed the Foreclosure sale and obtained such patents in exchange for extinguishing our outstanding secured indebtedness, while we retained our non-patent intellectual property, including trade secrets and know-how. Following the Foreclosure, we have adjusted our laser business to focus on licensing certain intellectual property, as well as using retained intellectual property primarily for purposes of product development related to our new dual-use Defense and Security Platform, as described below.

On February 27, 2026, we effected a 1-for-4.99 reverse stock split of our Common Stock (the “2026 Reverse Stock Split”). The 2026 Reverse Stock Split has been reflected retroactively to all Common Stock and per share amounts. Proportional adjustments were made to the number of shares of Common Stock issuable upon exercise, vesting, or conversion of our outstanding stock options, restricted stock units, warrants, convertible notes, preferred stock, and other instruments convertible into or exercisable for Common Stock, as well as the applicable exercise prices, conversion prices, and per share grant date fair values.

Our Transformation Plan

In January 2025, we adopted a new business plan focused on building a stable foundation for the future business, including addressing outstanding payables, entering into joint development agreements, and investing in controlling interests in strategic targets (the “Transformation Plan”). In connection with the Transformation Plan, we agreed to certain governance changes, including the appointment of Alessandro Zamboni as our Executive Chairman and changes to our Board of Directors.

Our Dual-Use Defense and Security Platform

Pursuant to our Transformation Plan, we have become a defense, security, and critical-infrastructure technology company focused on the development, integration, and deployment of dual-use, non-kinetic, and software-orchestrated solutions addressing modern security and resilience challenges across military, governmental, and civilian domains. We operate a modular, platform-based business model that integrates directed-energy technologies, electronic-warfare capabilities, and a software-centric command, control, and orchestration layer through a combination of wholly owned subsidiaries, strategic investments and partnerships, and industrial cooperation arrangements.

During 2025, we undertook a comprehensive strategic transformation designed to reposition us from a legacy industrial laser manufacturer into a dual-use defense and security platform (“Defense and Security Platform”). As part of this transformation, we realigned our operating model toward licensing, joint development, system integration, and asset-light manufacturing, while retaining and expanding core non-patent intellectual property, engineering know-how, software capabilities, and system-architecture expertise.

Our Defense and Security Platform operates as a vertically integrated stack of capabilities, with each layer building upon foundational elements to deliver comprehensive mission capability. Our platform is designed to provide separate layers of distinct functional capabilities while integrating with adjacent layers through a unified software-defined control infrastructure, which enables both independent operation of specific capabilities and coordinated multi-layer mission execution. These layers consist of software governance, including AI-driven orchestration software, risk management platforms, unified command and full auditability; directed energy and electronic warfare (EW) effects, including laser systems, electro-magnetic capabilities and sensor integration; physical integration, including vehicle systems, tactical deployment and field operations; mobile manufacturing, including deployable production and rapid capability deployment; and commercial acceleration, including market access, regulatory expertise and defense partnerships.

In connection with this transformation, in early 2026, we completed the acquisition of Lyocon S.r.l., an Italian photonics and laser-engineering company specializing in the design, development, and production of advanced laser sources, optics, electronics, and customized laser systems for industrial, medical, and high-reliability applications. This acquisition has expanded our in-house engineering, assembly, testing, and demonstration capabilities for laser-based and directed-energy systems applicable to both defense and civilian security use cases. These use cases include the protection of critical infrastructure, ports, borders, transportation hubs, and

other sensitive assets, as well as applications in agri-tech and food-system resilience, where laser-based technologies may be applied to mitigate operational, environmental, and supply-chain risks. We also entered into industrial and network cooperation arrangements with defense and technology partners, including Tekne S.p.A., a defense-tech company that specializes in the design, production, and outfitting of a diverse range of vehicles, including industrial and military applications, as well as electronic devices for defense and security, advanced telecommunications, and tracking systems. These arrangements are intended to support scalable production, system integration, and access to established defense and dual-use supply chains.

A central pillar of our platform is our software and data-orchestration capability, which is being developed and expanded through Orbit S.r.l. (“Orbit”), an Italian software company specializing in digitalizing operational resilience solutions for mission-critical corporations. We acquired a 10.7% ownership interest in Orbit in October 2025 and an additional 11.3% ownership interest in January 2026. As a result of owning an approximate 22% ownership interest in Orbit in January 2026, we obtained control of Orbit’s board of directors and now hold a controlling position in Orbit. Orbit provides a software platform focused on operational resilience, data integration, and decision support, enabling the coordination, monitoring, and governance of complex systems and assets. Within our platform architecture, Orbit’s software capabilities are intended to function as a unifying software-defined control layer supporting sensor fusion, situational awareness, workflow orchestration, and auditability across both kinetic and non-kinetic components, as well as across defense, civilian, and critical-infrastructure environments.

Our Defense and Security Platform is designed to be applicable not only in military and governmental contexts, but also in civilian critical sectors where regulatory frameworks increasingly emphasize operational resilience, continuity of essential services, and systemic risk management. These sectors include financial services, energy, transportation, agriculture and food systems, and other critical-infrastructure operators. In this context, certain agri-tech applications-such as precision laser-based systems aimed at reducing dependency on chemical inputs, improving crop reliability, and mitigating environmental and operational risks-are viewed by us as part of a broader security and resilience framework related to food security and supply-chain stability.

This regulatory and risk-management focus underpins Orbit’s current portfolio of customers, which consists primarily of financial institutions and selected critical-infrastructure service providers, and informs our broader strategy of addressing converging defense, security, environmental, and civilian resilience requirements through a common, software-orchestrated platform approach.

In addition, we recognize that certain portions of our business-particularly those involving hardware-intensive solutions such as directed-energy systems, special-purpose platforms, and integrated defense or security assets-require capital-intensive supply chains and careful management of inventory, procurement cycles, and working capital in order to scale effectively. As part of our long-term platform strategy, we have made a strategic investment in a single financial-technology platform, Supply@ME Capital Plc (“SYME”), which is focused on working-capital solutions with particular emphasis on inventory-related financing and optimization.

This SYME investment is intended to support the scaling of our operating businesses by enhancing supply-chain resilience, liquidity management, and capital efficiency, particularly in contexts where inventory ownership, production lead times, and delivery cycles are material to execution. Our investment in SYME is positioned as a supporting, integrated capability enabler within our platform and does not represent a broader financial-services business or investment strategy to us.

In furtherance of our Defense and Security Platform, in January 2026, we partnered with Maddox Defense Incorporated (“Maddox”) on a contractual joint venture for the development of a modular, containerized, mobile additive manufacturing platform capable of producing drone components, pods, mission-critical structural parts and related components for defense and security applications.

We continue to evaluate and pursue strategic investments, acquisitions, joint ventures, and cooperation initiatives that complement our platform strategy, expand our technological and software capabilities, and support long-term participation in defense and dual-use security, resilience, and food-system stability programs in the United States, Europe, and other allied markets.

Implications of Being a Smaller Reporting Company

We are a “smaller reporting company” as defined in Item 10(f)(1) of Regulation S-K. Smaller reporting companies may take advantage of certain reduced disclosure obligations, including, among other things, providing only two years of audited financial statements. We will remain a smaller reporting company until the last day of the fiscal year in which (i) the market value of our ordinary shares held by non-affiliates exceeds $250 million as of the prior June 30 or (ii) our annual revenue exceeded $100 million during such completed fiscal year and the market value of our ordinary shares held by non-affiliates exceeds $700 million as of the prior June 30.

THE OFFERING

RISK FACTORS

Before purchasing any of the securities, you should carefully consider the risk factors incorporated by reference in this prospectus from our Annual Report on Form 10-K for the fiscal year ended December 31, 2025, filed with the SEC on March 31, 2026 (the “Annual Report”), and any subsequent updates described in our Quarterly Reports on Form 10-Q and Current Reports on Form 8-K, as well as the risks, uncertainties and additional information set forth in our SEC reports on Forms 10-K, 10-Q and 8-K and in the other documents incorporated by reference in this prospectus. For a description of these reports and documents, and information about where you can find them, see “Where You Can Find More Information” and “Incorporation of Certain Information By Reference.” Additional risks not presently known or that we presently consider to be immaterial could subsequently materially and adversely affect our financial condition, results of operations, business and prospects.

THE STANDBY EQUITY PURCHASE AGREEMENT

On May 30, 2025, we entered into a Standby Equity Purchase Agreement (the “SEPA”) with the Selling Stockholder pursuant to which we have the right to sell to the Selling Stockholder up to $100 million of shares of our Common Stock (the “Commitment Amount”), subject to certain limitations and conditions set forth in the SEPA, from time to time during the term of the SEPA. In connection with the SEPA, we agreed to register for resale the Common Stock issued to the Selling Stockholder. Sales of shares of Common Stock to the Selling Stockholder under the SEPA, and the timing of any such sales, are at our option, and we are under no obligation to sell any shares of Common Stock to the Selling Stockholder under the SEPA. Registration statements were declared effective by the SEC allowing the Selling Stockholder to resell up to 20 million, 30 million and 130 million shares of Common Stock on July 24, 2025, September 23, 2025, and December 19, 2025, respectively. We are filing a new registration statement of which this prospectus forms a part to register an additional 60 million shares of Common Stock that may be resold by the Selling Stockholder.

Upon the satisfaction of the conditions to the Selling Stockholder’s purchase obligation set forth in the SEPA, including having a registration statement registering the resale of the shares of Common Stock issuable under the SEPA declared effective by the SEC, we will have the right, but not the obligation, from time to time at our discretion until the SEPA is terminated to direct the Selling Stockholder to purchase a specified number of shares of Common Stock (“Advance”) by delivering written notice to the Selling Stockholder (“Advance Notice”). While there is no mandatory minimum amount for any Advance, it may not exceed an amount equal to 100% of the average of the daily traded amount during the five consecutive trading days immediately preceding an Advance Notice.

The shares of Common Stock purchased pursuant to an Advance delivered by us will be purchased at a price equal to 97% of the lowest daily VWAP (as defined below) of the shares of Common Stock during the three consecutive trading days commencing on the date of the delivery of the Advance Notice, other than the daily VWAP on a day in which the daily VWAP is less than a minimum acceptable price as stated by us in the Advance Notice or there is no VWAP on the subject trading day, in which cases the size of the Advance may be reduced to account for such day(s) in which the daily VWAP is less than the applicable minimum acceptable price or there is no VWAP. We may establish a minimum acceptable price in each Advance Notice below which we will not be obligated to make any sales to the Selling Stockholder. “VWAP” is defined as the daily volume weighted average price of the shares of Common Stock for such trading day on the NYSE American during regular trading hours as reported by Bloomberg L.P.

Under applicable NYSE American rules, in no event may we issue to the Selling Stockholder under the SEPA shares equal to greater than 19.99% of the shares of Common Stock outstanding immediately prior to the execution of the SEPA (the “Exchange Cap”), unless we obtain stockholder approval to issue shares of Common Stock in excess of the Exchange Cap in accordance with applicable NYSE American rules. At our annual meeting of stockholders held on July 9, 2025 (the “2025 Annual Meeting”), our stockholders approved issuances of Common Stock pursuant to the SEPA in excess of 19.99%. In addition, in accordance with the terms of the SEPA, we may not issue or sell any shares of Common Stock to the Selling Stockholder under the SEPA which, when aggregated with all other shares of Common Stock then beneficially owned by the Selling Stockholder and its affiliates (as calculated pursuant to Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and Rule 13d-3 thereunder), would result in the Selling Stockholder’s then beneficially owning more than 4.99% of the then outstanding shares of Common Stock.

We will control the timing and amount of any sales of shares of Common Stock to the Selling Stockholder. Actual sales of shares of Common Stock to the Selling Stockholder under the SEPA will depend on a variety of factors to be determined by us from time to time, which may include, among other things, market conditions, the trading price of the Common Stock and determinations by us as to the appropriate sources of funding for our business and operations.

The SEPA will automatically terminate on the earlier of (i) the 36-month anniversary of the date of the SEPA and (ii) the date on which the Selling Stockholder shall have made payment of Advances pursuant to the SEPA for Common Stock equal to the Commitment Amount. We have the right to terminate the SEPA at no cost or penalty upon five (5) trading days’ prior written notice to the Selling Stockholder, provided that (i) there are no outstanding Advance Notices for which shares of Common Stock need to be issued and (ii) we have paid all amounts owed to the Selling Stockholder pursuant to the SEPA. We and the Selling Stockholder may also agree to terminate the SEPA by mutual written consent. Neither we nor the Selling Stockholder may assign or transfer respective rights and obligations under the SEPA, and no provision of the SEPA may be modified or waived other than by an instrument in writing signed by both parties.

As consideration for the Selling Stockholder’s commitment to purchase the shares of Common Stock pursuant the SEPA, we paid the Selling Stockholder (i) a structuring fee in the amount of $25,000 and (ii) a commitment fee in Common Stock (the “Commitment Shares”) in an amount equal to 1% of the Commitment Amount, or $1,000,000, which was paid 50% with the issuance of 267,059 shares of Common Stock on June 5, 2025 and 50% with the issuance of 267,059 shares of Common Stock on July 15, 2025.

The SEPA contains customary representations, warranties, conditions and indemnification obligations of the parties. The representations, warranties and covenants contained in such agreements were made only for purposes of such agreements and as of specific dates, were solely for the benefit of the parties to such agreements and may be subject to limitations agreed upon by the contracting parties.

The net proceeds under the SEPA to us will depend on the frequency and prices at which we sell Common Stock to the Selling Stockholder. Until such time as the Debenture issued to the Selling Stockholder has been indefeasibly paid in full, all proceeds to us from sales under the SEPA are required to be applied to the repayment of the Debenture. Following the repayment of the Debenture, we expect that any proceeds received from sales to the Selling Stockholder will be used primarily for working capital and general corporate purposes and for purposes of implementing our previously announced Transformation Plan.

USE OF PROCEEDS

Any sales of Common Stock by the Selling Stockholder pursuant to this prospectus will be solely for the Selling Stockholder’s accounts. We will not receive any proceeds from any such sales.

We may receive up to $97 million aggregate gross proceeds under the SEPA from any sales we make to the Selling Stockholder pursuant to the SEPA. The net proceeds from additional sales, if any, under the SEPA, will depend on the frequency and prices at which we sell our Common Stock to the Selling Stockholder after the date of this prospectus. See the section titled “Plan of Distribution” in this prospectus for more information.

Until such time as the Debenture issued to the Selling Stockholder has been indefeasibly paid in full, all proceeds to us from sales under the SEPA are required to be applied to the repayment of the Debenture. Following repayment of the Debenture, we expect to use any proceeds that we receive under the SEPA primarily for working capital and general corporate purposes and to implement our announced Transformation Plan. As of the date of this prospectus, we cannot specify with certainty all of the particular uses, and the respective amounts we may allocate to those uses, for any net proceeds we receive.

The Selling Stockholder will pay any underwriting discounts, selling commissions and stock transfer taxes and fees incurred by the Selling Stockholder in connection with any sale of its shares of Common Stock. We will generally bear all other costs, fees and expenses incurred in effecting the registration of the shares of Common Stock covered by this prospectus, including, without limitation, all registration and filing fees, NYSE American listing fees and fees and expenses of Company counsel and independent registered public accountants.

SELLING stockHOLDER

This prospectus relates to the possible resale from time to time by the Selling Stockholder of any or all of the shares of Common Stock that may be issued by us to the Selling Stockholder under the SEPA. For additional information regarding the issuance of Common Stock covered by this prospectus, see the section titled “The Standby Equity Purchase Agreement” above.

We are registering the shares of Common Stock in connection with the SEPA in order to permit the Selling Stockholder to offer the shares of Common Stock for resale from time to time. The Selling Stockholder has not had any material relationship with us within the past three years, except for (i) the transactions contemplated by the SEPA, (ii) the Company’s issuance of the Debenture in the amount of $25,000,000 and issuance of warrants to purchase 46,092,188 shares of Common Stock to the Selling Stockholder on December 17, 2025, and (iii) the Company’s issuance of a debenture in the amount of $1,250,000 to the Selling Stockholder in exchange for a capital infusion of $1,100,000, which was repaid in the third quarter of 2025.

The table below presents information regarding the Selling Stockholder and the shares of Common Stock that it may offer from time to time under this prospectus. This table is prepared based on information supplied to us by the Selling Stockholder and reflects beneficial ownership as of April 20, 2026. The number of shares of Common Stock in the column “Maximum Number of Shares of Common Stock to be Offered Pursuant to this Prospectus” represents all of the shares of Common Stock that the Selling Stockholder may offer under this prospectus. The Selling Stockholder may sell some, all or none of its shares of Common Stock in this offering. We do not know how long the Selling Stockholder will hold the shares of Common Stock before selling them.

Beneficial ownership is determined in accordance with Rule 13d-3(d) promulgated by the SEC under the Exchange Act and includes shares of Common Stock with respect to which the Selling Stockholder has voting and investment power. The percentage of shares of Common Stock beneficially owned by the Selling Stockholder prior to the offering shown in the table below is based on an aggregate of 169,497,579 shares of our Common Stock outstanding on April 20, 2026. Because the purchase price of the shares of Common Stock issuable under the SEPA is determined on each applicable purchase date, the number of shares of Common Stock that may actually be sold by the Company to the Selling Stockholder under the SEPA may be fewer than the number of shares of Common Stock being offered by this prospectus. The fourth column assumes the sale of all of the shares of Common Stock offered by the Selling Stockholder pursuant to this prospectus.

PLAN OF DISTRIBUTION

The shares of Common Stock offered by this prospectus are being offered by the Selling Stockholder. The shares of Common Stock may be sold or distributed from time to time by the Selling Stockholder directly to one or more purchasers or through brokers, dealers, or underwriters who may act solely as agents at market prices prevailing at the time of sale, at prices related to the prevailing market prices, at negotiated prices, or at fixed prices, which may be changed. The sale of the shares of Common Stock offered by this prospectus could be effected in one or more of the following methods:

In order to comply with the securities laws of certain states, if applicable, the shares of Common Stock may be sold only through registered or licensed brokers or dealers. In addition, in certain states, the shares of Common Stock may not be sold unless they have been registered or qualified for sale in the state or an exemption from the state’s registration or qualification requirement is available and complied with.

The Selling Stockholder is an “underwriter” with respect to the Offered Shares within the meaning of Section 2(a)(11) of the Securities Act. The Selling Stockholder has informed us that it intends to use one or more registered broker-dealers to effectuate all sales, if any, of our Common Stock that it has acquired and may in the future acquire from us pursuant to the SEPA. Such sales will be made at prices and at terms then prevailing or at prices related to the then current market price. Each such registered broker-dealer will be an underwriter within the meaning of Section 2(a)(11) of the Securities Act. The Selling Stockholder has informed us that each such broker-dealer will receive commissions from the Selling Stockholder that will not exceed customary brokerage commissions.

Brokers, dealers, underwriters or agents participating in the distribution of the shares of our Common Stock offered by this prospectus may receive compensation in the form of commissions, discounts, or concessions from the purchasers, for whom the broker-dealers may act as agent, of the shares of Common Stock sold by the Selling Stockholder through this prospectus. The compensation paid to any such particular broker-dealer by any such purchasers of shares of our Common Stock sold by the Selling Stockholder may be less than or in excess of customary commissions. Neither we nor the Selling Stockholder can presently estimate the amount of compensation that any agent will receive from any purchasers of shares of our Common Stock sold by the Selling Stockholder.

We know of no existing arrangements between the Selling Stockholder or any other stockholder, broker, dealer, underwriter or agent relating to the sale or distribution of the shares of our Common Stock offered by this prospectus.

We may from time to time file with the SEC one or more supplements to this prospectus or amendments to the registration statement of which this prospectus forms a part to amend, supplement or update information contained in this prospectus, including, if and when required under the Securities Act, to disclose certain information relating to a particular sale of shares of Common Stock offered by this prospectus by the Selling Stockholder, including the names of any brokers, dealers, underwriters or agents participating in the distribution of such shares of Common Stock by the Selling Stockholder, any compensation paid by the Selling Stockholder to any such brokers, dealers, underwriters or agents, and any other required information.

We will pay the expenses incident to the registration under the Securities Act of the offer and sale of the shares of our Common Stock covered by this prospectus by the Selling Stockholder.

We also have agreed to indemnify the Selling Stockholder and certain other persons against certain liabilities in connection with the offering of shares of our Common Stock offered hereby, including liabilities arising under the Securities Act or, if such indemnity is unavailable, to contribute amounts required to be paid in respect of such liabilities. The Selling Stockholder has agreed to indemnify us against liabilities under the Securities Act that may arise from certain written information furnished to us by the Selling Stockholder specifically for use in this prospectus or, if such indemnity is unavailable, to contribute amounts required to be paid in respect of such liabilities. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to our directors, officers, and controlling persons, we have been advised that in the opinion of the SEC this indemnification is against public policy as expressed in the Securities Act and is therefore, unenforceable.

We have advised the Selling Stockholder that it is required to comply with Regulation M promulgated under the Exchange Act. With certain exceptions, Regulation M precludes the Selling Stockholder, any affiliated purchasers, and any broker-dealer or other person who participates in the distribution from bidding for or purchasing, or attempting to induce any person to bid for or purchase any security that is the subject of the distribution until the entire distribution is complete. Regulation M also prohibits any bids or purchases made in order to stabilize the price of a security in connection with the distribution of that security. All of the foregoing may affect the marketability of the securities offered by this prospectus.

This offering will terminate on the date that all shares of our Common Stock offered by this prospectus have been sold by the Selling Stockholder.

Description of Securities WE ARE OFFERING

The following descriptions of the Common Stock and certain provisions of our amended and restated certificate of incorporation, as amended (the “Certificate of Incorporation”), and amended and restated bylaws, as amended (“Bylaws”), are summaries and are qualified by reference to such documents (together the “Governing Documents”), copies of which have been filed as exhibits to the Company’s Annual Reports on Form 10-K and other periodic reports filed with the SEC, as well as to the relevant provisions of the general corporation law of the state of Delaware (the “DGCL”).

Common Stock

Holders of our Common Stock, par value $0.0001 per share, are entitled to one (1) vote for each share held as of the applicable record date on all matters properly submitted to a vote of stockholders, including the election or removal of directors. Unless specified in our Governing Documents, or as required by applicable provisions of the DGCL or applicable stock exchange rules, the affirmative vote of a majority of the votes cast at any meeting of the Company stockholders at which there is a quorum by the stockholders present in person or represented by proxy at the meeting and entitled to vote thereon will be required to approve any such matter voted on by stockholders. The Company’s board of directors is divided into three (3) classes, each of which generally serve for a term of three (3) years with only one (1) class of directors being elected each year. The Company’s stockholders do not have cumulative voting rights in the election of directors. Accordingly, holders of a majority of the voting power of the outstanding capital stock of the Company will be able to elect all of the directors.

Subject to preferences that may be applicable to any preferred stock outstanding at the time, the holders of outstanding shares of our Common Stock are entitled to receive ratably any dividends declared by the Company’s Board of Directors out of assets legally available. Upon the liquidation, dissolution or winding up, holders of our Common Stock are entitled to share ratably in all assets remaining after payment of liabilities and the liquidation preference of any then outstanding shares of preferred stock. Holders of our Common Stock have no preemptive or conversion rights or other subscription rights. There are no redemption or sinking fund provisions applicable to our Common Stock.

Anti-Takeover Effects of the Company’s Certificate of Incorporation, Bylaws and Certain Provisions of Delaware Law

The Certificate of Incorporation, our Bylaws and the DGCL contain provisions as summarized in the following paragraphs that are intended to enhance the likelihood of continuity and stability in the composition of the Company’s board of directors. These provisions are intended to avoid costly takeover battles, reduce the Company’s vulnerability to a hostile change of control and enhance the ability of the Company’s board of directors to maximize stockholder value in connection with any unsolicited offer to acquire the Company. However, these provisions may have an anti-takeover effect and may delay, deter, or prevent a merger or acquisition of the Company by means of a tender offer, a proxy contest or other takeover attempt that a stockholder might consider in its best interest, including those attempts that might result in a premium over the prevailing market price for the shares of Common Stock held by stockholders.

These provisions are designed to enhance the likelihood of continued stability in the composition of the Company’s board of directors and its policies, to discourage certain types of transactions that may involve an actual or threatened acquisition of our Company and to reduce our vulnerability to an unsolicited acquisition proposal. We also designed these provisions to discourage certain tactics that may be used in proxy fights. However, these provisions could have the effect of discouraging others from making tender offers for our shares and, as a consequence, they may also reduce fluctuations in the market price of our shares that could result from actual or rumored takeover attempts.

Delaware General Corporation Law Section 203

As a Delaware corporation, we are also subject to the anti-takeover provisions of Section 203 of the DGCL, which generally prohibits a Delaware corporation from engaging in a “business combination” (as defined in the statute) with an “interested stockholder” (as defined in the statute) for a period of three (3) years after the date of the transaction in which the person first becomes an interested stockholder, unless the business combination or the transaction by which the applicable stockholder became an interested stockholder is approved in advance by a majority of the independent directors or by the holders of at least two-thirds of the voting power of the outstanding disinterested shares. The application of Section 203 of the DGCL could also have the effect of delaying or preventing a change of control of us.

Dissenters’ Rights of Appraisal and Payment

Under the DGCL, with certain exceptions, our stockholders have appraisal rights in connection with certain mergers, consolidations or conversions of the Company. Pursuant to the DGCL, stockholders who properly request and perfect appraisal rights in connection with such merger, consolidation or conversion will have the right to receive payment of the fair value of their shares as determined by the Delaware Court of Chancery.

Stockholders’ Derivative Actions

Under the DGCL, any of our stockholders may bring an action in our name to procure a judgment in our favor, also known as a derivative action, if certain conditions are met, provided that the stockholder bringing the action is a holder of our shares at the time of the transaction to which the action relates or such stockholder’s stock thereafter devolved by operation of law.

Limitations on Liability and Indemnification of Officers and Directors

The DGCL authorizes corporations to limit or eliminate the personal liability of directors and certain officers to corporations and their stockholders for monetary damages for breaches of directors’ and officers’ fiduciary duties, subject to certain exceptions. The Governing Documents include certain provisions that eliminate the personal liability of directors and officers for monetary damages for any breach of fiduciary duty as a director or officer, except to the extent such exemption from liability or limitation thereof is not permitted under the DGCL. The effect of these provisions is to eliminate the rights of the Company and its stockholders, through stockholders’ derivative suits on the Company’s behalf, to recover monetary damages from a director or officer for breach of fiduciary duty as a director or officer in certain circumstances, including breaches resulting from grossly negligent behavior. However, exculpation does not apply to any director if the director has acted in bad faith, knowingly or intentionally violated the law, authorized illegal dividends or redemptions or derived an improper benefit from his or her actions as a director and does not apply to officers if the officer has acted in bad faith, knowingly or intentionally violated the law or derived an improper benefit from his or her actions as a director or in the context of an action by or in the right of the Company.

The Certificate of Incorporation provides that we must indemnify our directors, and our Bylaws provide that we must indemnify and advance expenses to our directors and officers, to the fullest extent authorized by the DGCL. We also are expressly authorized to carry directors’ and officers’ liability insurance providing indemnification for our directors, officers, employees and agents for some liabilities. We believe that these indemnification and advancement provisions and the authority to carry insurance are useful to attract and retain qualified directors and executive officers.

The limitation of liability, advancement and indemnification provisions in the Governing Documents may discourage stockholders from bringing a lawsuit against directors for breach of their fiduciary duty.

These provisions also may have the effect of reducing the likelihood of derivative litigation against directors and officers, even though such an action, if successful, might otherwise benefit us and our stockholders. In addition, your investment may be adversely affected to the extent we pay the costs of settlement and damage awards against directors and officers pursuant to these indemnification provisions.

The validity of the securities offered hereby will be passed upon for us by Holland & Hart LLP, Denver, Colorado.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 14. Other Expenses of Issuance and Distribution.

The following table sets forth an estimate of the fees and expenses payable by us in connection with the issuance and distribution of the securities being registered. All amounts are estimated, except the Securities and Exchange Commission (“SEC”) registration fee. All of the expenses below will be paid by us.

Item 15. Indemnification of Directors and Officers.

Our Certificate of Incorporation provides that all of our directors, officers, employees and agents shall be entitled to be indemnified by us to the fullest extent permitted by Section 145 of the Delaware General Corporation Law (the “DGCL”). We are incorporated under the laws of the State of Delaware. Under Delaware law, a corporation may indemnify any person who was or is a party or is threatened to be made a party to an action (other than an action by or in the right of the corporation) by reason of his or her service as a director or officer of the corporation, or his or her service, at the corporation’s request, as a director, officer, employee or agent of another corporation or other enterprise, against expenses (including attorneys’ fees) that are actually and reasonably incurred by him or her (“Expenses”), and judgments, fines and amounts paid in settlement that are actually and reasonably incurred by him or her, in connection with the defense or settlement of such action, provided that such person acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the corporation’s best interests, and, with respect to any criminal action or proceeding, had no reasonable cause to believe that his or her conduct was unlawful. Although Delaware law permits a corporation to indemnify any person referred to above against Expenses in connection with the defense or settlement of an action by or in the right of the corporation, provided that such person acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the corporation’s best interests, if such person has been judged liable to the corporation, indemnification is only permitted to the extent that the Court of Chancery (or the court in which the action was brought) determines that, despite the adjudication of liability, such person is entitled to indemnity for such Expenses as the court deems proper. The DGCL also provides for mandatory indemnification of any director, officer, employee or agent against Expenses to the extent such person has been successful in any proceeding covered by the statute. In addition, the DGCL provides the general authorization of advancement of a director’s or officer’s litigation expenses in lieu of requiring the authorization of such advancement by the board of directors in specific cases, and that indemnification and advancement of expenses provided by the statute shall not be deemed exclusive of any other rights to which those seeking indemnification or advancement of expenses may be entitled under any bylaw, agreement or otherwise.

Our amended and restated bylaws and restated certificate of incorporation provide for indemnification of our directors and officers and for advancement of litigation expenses to the fullest extent permitted by current Delaware law. In addition, we have entered into indemnification agreements with directors and officers that provide for indemnification and advancement of litigation expenses to fullest extent permitted by the DGCL.

We maintain a policy of directors’ and officers’ liability insurance which reimburses us for expenses which we may incur in connection with the foregoing indemnity provisions and which may provide direct indemnification to directors and officers where we are unable to do so.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to our directors, officers and controlling persons pursuant to the above, we have been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable.

Item 16. Exhibits.

(a) Exhibits

† Certain of the exhibits and schedules to these exhibits have been omitted in accordance with Regulation S‑K Item 601(a)(5). The registrant agrees to furnish a copy of all omitted exhibits and schedules to the SEC upon its request.

* Filed herewith.

** To be filed by amendment.

Item 17. Undertakings.

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 Commission 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 (1)(i), (ii), (iii) above do not apply if the registration statement is on Form S-1 and the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to section 13 or section 15(d) of the Exchange Act that are incorporated by reference in the registration statement.

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

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

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

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

ii. each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

(5) That, for the purpose of determining liability of the registrant under the Securities Act to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

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

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

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

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

(6) That, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act of 1933 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 of 1933 and will be governed by the final adjudication of such issue.

The undersigned registrant hereby undertakes that:

(1) For purposes of determining any liability under the Securities Act, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective.

(2) For the purpose of determining any liability under the Securities Act, each post-effective amendment that contains a form of prospectus 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
