CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus, any prospectus supplement and any related free writing prospectus, including the information incorporated by reference herein and therein, contains or may contain forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”) and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) that involve substantial risks and uncertainties. These forward-looking statements depend upon events, risks and uncertainties that may be outside of our control. All statements, other than statements related to present facts or current conditions or of historical facts, contained in this prospectus, any prospectus supplement and any related free writing prospectus, including the information incorporated by reference herein and therein, including statements regarding our strategy, future operations, future financial position, future revenues, and projected costs, prospects, plans and objectives of management, are forward-looking statements. Accordingly, these statements involve estimates, assumptions and uncertainties which could cause actual results to differ materially from those expressed in them. The words “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “intend,” “may,” “might,” “ongoing,” “plan,” “potential,” “predict,” “project,” “should,” “target,” “will,” “would,” or the negative of these terms or other comparable terminology are intended to identify forward-looking statements, although not all forward-looking statements contain these identifying words. Any forward-looking statements are qualified in their entirety by reference to the factors discussed under the heading “Risk Factors” in this prospectus, any prospectus supplement and any related free writing prospectus, or the documents incorporated by reference herein.

Forward-looking statements involve a number of risks, uncertainties and assumptions, and actual results or events may differ materially from those projected or implied in those statements. Important factors that could cause such differences include, but are not limited to: risks related to the rollout of our business and the timing of expected business milestones; our dependence on widespread acceptance and adoption of electric vehicles and increased installation of charging stations; our ability to maintain effective internal controls over financial reporting, including the remediation of identified material weaknesses in internal control over financial reporting relating to segregation of duties with respect to, and access controls to, its financial record keeping system, and our accounting staffing levels; our current dependence on sales of charging stations for most of our revenues; overall demand for electric vehicle charging and the potential for reduced demand if governmental rebates, tax credits and other financial incentives are reduced, modified or eliminated or governmental mandates to increase the use of electric vehicles or decrease the use of vehicles powered by fossil fuels, either directly or indirectly through mandated limits on carbon emissions, are reduced, modified or eliminated; potential adverse effects on our backlog, revenue and gross margins if customers increasingly claim clean energy credits and, as a result, they are no longer available to be claimed by us; the effects of competition on our future business; risks related to our dependence on its intellectual property and the risk that our technology could have undetected defects or errors; the risk that we conduct a portion of our operations through a joint venture exposes us to risks and uncertainties, many of which are outside of our control; changes in applicable laws or regulations; risks related to disruption of management time from ongoing business operations due to our joint ventures; risks relating to privacy and data protection laws, privacy or data breaches, or the loss of data; the possibility that we may be adversely affected by other economic, business, and/or competitive factors; and the risks identified under “Risk Factors” described or incorporated by reference in this prospectus.

We caution you not to rely on forward-looking statements, which reflect current beliefs and are based on information currently available as of the date a forward-looking statement is made. Forward-looking statements set forth herein speak only as of the date of this prospectus or the documents incorporated by reference in this prospectus, as applicable. Forward-looking statements are not guarantees of performance. There can be no assurance that future developments affecting us will be those that we have anticipated. These forward-looking statements involve a number of risks, uncertainties (some of which are beyond our control) or other assumptions that may cause actual results or performance to be materially different from those expressed or implied by these forward-looking statements. Other sections of this prospectus and the documents incorporated by reference herein describe additional factors that could adversely affect our business, financial condition or results of operations. We believe these factors include, but are not limited to, those described or incorporated by reference under “Risk Factors”. Should one or more of these risks or uncertainties materialize, or should any of our assumptions prove incorrect, actual results may vary in material

RISK FACTORS

Investing in our securities involves risks. You should carefully consider the risks, uncertainties and other factors described in our most recent Annual Report on Form 10-K, as supplemented and updated by subsequent Quarterly Reports on Form 10-Q and Current Reports on Form 8-K that we have filed or will file with the Securities and Exchange Commission (the “SEC”), and in other documents which are incorporated by reference into this prospectus, including all future filings we make with the SEC pursuant to Sections 13(a), 13(c), 14 or 15(d) of the Exchange Act, as well as the risk factors and other information contained in or incorporated by reference into any accompanying prospectus supplement before investing in any of our securities. Our financial condition, results of operations or cash flows could be materially adversely affected by any of these risks. The risks and uncertainties described in the documents incorporated by reference herein are not the only risks and uncertainties that you may face. For more information about our SEC filings, please see “Where You Can Find More Information” and “Incorporation of Certain Information by Reference.”

We have a limited operating history under the Flash Sports & Media platform and may not be able to successfully execute our business plan.

The Company completed the Merger with Flash on February 17, 2026. Flash was incorporated on August 7, 2023 and had not generated any revenue prior to the Merger. While IPG, which is now a wholly owned subsidiary of Flash and therefore of the Company, has generated revenue from cricket-related operations since 2020, the combined entity has a limited operating history as a publicly traded sports and media company. There can be no assurance that we will be able to successfully integrate the operations of Flash, IPG, and the Company, or that we will achieve profitability. Our prospects must be considered in light of the risks and uncertainties encountered by companies in the early stages of development in rapidly evolving markets.

We are substantially dependent on a single contractual relationship with Sri Lanka Cricket for a significant majority of our revenue.

Substantially all of IPG’s revenue is derived from the commercialization of rights granted under the Master Event Rights Agreement with SLC for the Lanka Premier League. The loss, non-renewal, or material modification of this agreement would have a material adverse effect on our business, financial condition, and results of operations. The Event Rights Agreement requires annual payment of an Event Rights Fee or provision of a bank guarantee by March 15 of each year; failure to make timely payment could result in termination of the Company’s rights for that year. Although the agreement provides for automatic one-year renewals, IPG’s rights must be secured annually, and there can be no assurance that the agreement will be renewed on favorable terms, or at all.

We have a going concern qualification and a history of net losses and accumulated deficits.

Both IPG and Flash have received going concern qualifications from their respective auditors. As of December 31, 2024, IPG had an accumulated deficit of approximately $4.6 million and a working capital deficit of approximately $1.9 million. Flash had an accumulated deficit of $500,000 as of December 31, 2024 and had never generated revenue. The Company (legacy urban-gro) had an accumulated deficit of approximately $120.6 million and a stockholders’ deficit of approximately $40.9 million as of December 31, 2025. There can be no assurance that the combined entity will achieve or sustain profitability.

Our revenue is concentrated among a limited number of customers and geographies.

For the year ended December 31, 2024, approximately 82% of IPG’s total revenue was generated from customers based in Sri Lanka, with the remaining 18% derived from Zimbabwe. In 2023, sales to four customers individually exceeded 10% of IPG’s total revenue, collectively representing approximately 53% of total revenue. The loss of any significant customer or a significant reduction in business from Sri Lanka or Zimbabwe could have a material adverse effect on our financial performance. The Company continues to focus on efforts to diversify its customer base to mitigate such risks.

Our business is dependent on the continued popularity and growth of cricket, particularly T20 cricket, in our target markets.

Our revenue is substantially derived from the commercialization of T20 cricket league rights. Any decline in the popularity of cricket or T20 cricket in Sri Lanka, or in international markets where we distribute media content, could reduce demand for media rights, sponsorships, franchise ownership, and ticketing, which would materially and adversely affect our business, financial condition, and results of operations.

We are subject to risks associated with international operations.

The Company conducts operations in the United Arab Emirates, Sri Lanka, Zimbabwe, and other international markets, and is subject to risks inherent in international operations, including political and economic instability, currency fluctuation risk, regulatory uncertainty, foreign tax regimes (including the recently enacted UAE Corporate Tax), sanctions and trade restrictions, cultural and legal differences, and challenges in enforcing contractual rights across jurisdictions. Any of these factors could materially and adversely affect our operations and financial results.

We depend on key personnel, including the founder and chairman of IPG.

The Company’s success depends in significant part on the continued services and leadership of key individuals, including Anil Mohan Sankhdhar, the founder and chairman of IPG, who has been instrumental in building the Company’s relationships with SLC, franchise owners, sponsors, and broadcast partners, and Bradley Nattrass, the Company’s Chairman and Chief Executive Officer. The loss of any of these individuals’ services could have a material adverse effect on our business and operations. We do not currently maintain key-person life insurance on any of our executives.

Force majeure events, including pandemics, natural disasters, terrorism, and political unrest, could disrupt our tournament operations.

The LPL and our other cricket events are live, in-person sporting events that are subject to disruption or cancellation due to force majeure events. Under the Event Rights Agreement, the full Event Rights Fee remains payable by the Event Rights Partner to SLC even if the whole or any part of the Tournament is curtailed, cancelled, or abandoned due to any Force Majeure event, after the date of commencement of the Tournament. Force Majeure events include, but are not limited to, acts of God, war, riot, strike, civil commotion, terrorism, pandemics, epidemics, fire, earthquake, storm, flood, tsunami, explosion, and acts of Government. Any such disruption could materially and adversely affect our revenue, reputation, and operations.

Our expansion into new markets and new business verticals involves significant risks and uncertainties.

We have announced expansion plans for T20 cricket league operations in Malaysia, Zimbabwe, Bangladesh, and the United Arab Emirates. We are also pursuing potential strategic combinations and partnerships in the esports and entertainment sectors, including a potential combination with Infinity Esports & Gaming, a Latin American esports organization that operates gaming centers across multiple countries and holds branded intellectual properties, and the potential development of Dune Bridge Capital, an investment and strategic capital deployment vertical focused on film, television, sports, and digital media. Each of these initiatives involves significant execution risk, including the need to negotiate and execute definitive agreements, secure regulatory approvals, recruit qualified local personnel, obtain adequate financing, and build local infrastructure. As of the date of this Report, no definitive agreements have been entered into with respect to the esports or entertainment verticals. There can be no assurance that any of these expansion or diversification initiatives will be completed on the terms anticipated, or at all, or that they will generate the revenue or returns expected.

We face significant competition in the sports media and entertainment industry.

The sports media and entertainment industry is highly competitive. We compete for viewership, sponsorship dollars, franchise investment, media rights fees, and talent with larger, better-capitalized companies and established cricket leagues, including the IPL, BBL, CPL, PSL, and SA20. Many of our competitors have significantly greater financial, technical, marketing, and other resources than we do. There can be no assurance that we will be able to compete effectively.

Risks Related to the Merger and Integration

The Merger may not achieve its intended benefits, and integration of the combined businesses involves significant risks.

The success of the Merger depends on, among other things, our ability to successfully integrate the operations, technologies, and personnel of Flash, IPG, and the legacy urban-gro business, achieve anticipated revenue growth, realize cost synergies, and retain key customers, partners, and employees. Integration may be more difficult, time-consuming, or costly than expected, and there can be no assurance that we will realize the expected benefits of the Merger.

Following the Merger, former Flash stockholders are expected to own approximately 90% of the combined company, resulting in significant dilution to existing stockholders.

Under the terms of the Merger Agreement, Flash stockholders received shares of UGRO common stock equal to 19.99% of the outstanding shares immediately prior to certain prior issuances, as well as shares of newly created non-voting convertible preferred stock that, upon stockholder approval of the conversion, would result in former Flash stockholders owning approximately 90% of the combined company on a fully-converted basis. This represents substantial dilution to the Company’s existing stockholders.

The Company changed its independent auditor in connection with the Merger, which may increase the risk of accounting errors or restatements.

On February 27, 2026, the Company dismissed Sadler, Gibb & Associates, LLC as its independent registered public accounting firm and appointed Suri and Co., Chartered Accountants of Chennai, India to audit the Company’s financial statements for the year ended December 31, 2025. The transition to a new auditor during a period of significant business transformation increases the risk of accounting errors, delays in financial reporting, or the need for restatements.

We have a history of non-compliance with Nasdaq listing standards and may be unable to maintain our Nasdaq listing.

The Company has experienced multiple instances of non-compliance with Nasdaq listing standards, including the minimum bid price requirement, timely filing of periodic reports, minimum stockholders’ equity requirement, and annual meeting requirement. While the Company regained compliance with these requirements as of March 2026, Nasdaq has placed the Company on a one-year Discretionary Panel Monitor under Listing Rule 5815(d)(4)(A). Any future non-compliance could result in delisting, which would materially and adversely affect the liquidity and trading price of our common stock.

We have limited liquidity and may require additional financing to fund our operations.

As of December 31, 2025, the Company had cash of approximately $10,000 and negative working capital of approximately $41.1 million. Our ability to continue operations is dependent on our ability to generate sufficient revenue and/or obtain financing. There can be no assurance that additional financing will be available on acceptable terms, or at all. If we are unable to obtain sufficient amounts of additional capital, we may be required to reduce the scope of our planned development, which could harm our business, financial condition, and operating results.

We have significant outstanding liabilities and legal proceedings that could adversely affect our financial condition.

The Company has significant accounts payable, contract liabilities, notes payable, and accrued expenses. Additionally, the Company is subject to various legal proceedings, including lawsuits by creditors, equipment suppliers, and former contractors. Adverse outcomes in any of these proceedings could materially affect our financial position and results of operations.

Risks Related to Regulatory and Legal Matters

We are subject to anti-corruption, anti-bribery, and sports integrity laws and regulations.

The Company and its subsidiaries, sub-licensees, franchise holders, and team owners are required to comply with anti-corruption and anti-bribery laws in all jurisdictions in which we operate, as well as ICC anti-corruption codes. Any violation of these laws or codes could result in criminal penalties, fines, suspension, or termination of our Event Rights, any of which could have a material adverse effect on our business.

Changes in tax laws or regulations, including the recently enacted UAE Corporate Tax, could increase our tax burden.

IPG is subject to the UAE Corporate Tax Law effective January 1, 2024, which imposes a 9% tax on taxable income exceeding the exemption threshold. Changes in applicable tax laws or their interpretation, or the enactment of new taxes in jurisdictions where we operate, could increase our effective tax rate and adversely affect our financial results.

The Event Rights Agreement is governed by Sri Lankan law and disputes are subject to international arbitration, which may be costly and time-consuming.

The Event Rights Agreement is governed by the laws of Sri Lanka, and disputes are subject to arbitration in Colombo under the Rules of the International Chamber of Commerce. The number of arbitrators shall be three, and each party shall be entitled to select one arbitrator each, with the third selected jointly to act as Chairman of the Arbitral Tribunal. Enforcing contractual rights through international arbitration may be more costly, time-consuming, and uncertain than litigation in U.S. courts, and arbitral awards may be difficult to enforce in other jurisdictions.

We had negative cash flow from operations for the fiscal years ended December 31, 2025 and December 31, 2024.

We had negative cash flow from operations of $2.1 million and $3.0 million for the years ended December 31, 2025 and 2024, respectively. To the extent that we have negative cash flow from operations in future periods, we may need to allocate a portion of our cash reserves to fund such negative cash flow. We may also be required to raise additional funds through the issuance of equity or debt securities. We may not be able to generate positive cash flow from our operations and additional capital or other types of financing may not be available when needed or on terms favorable to us.

We may continue to incur losses in the near future, which may impact our ability to implement our business strategy and adversely affect our financial condition.

While we are focused significantly on controlling our operating expenses by managing variable expenses, employee count, and marketing activities in order to become cash flow positive, these measures may adversely affect our future operating results if we are unable to support the business effectively. In turn, this would have a negative impact on our financial condition and potentially our share price.

We may not become profitable or generate sufficient profits from operations in the future. If our revenues do not continue to grow or our gross profits deteriorate substantially, we are likely to continue to experience losses in future periods. Collectively, this may impact our ability to implement our business strategy and adversely affect our financial condition. This potentially would have a negative impact on our share price.

We may be forced to litigate to defend our intellectual property rights, or to defend against claims by third parties against urban-gro relating to intellectual property rights.

We may be forced to litigate to enforce or defend our intellectual property rights, to protect our trade secrets or to determine the validity and scope of other parties’ proprietary rights. Any such litigation could be very costly and could distract our management from focusing on operating our business. The existence and/or outcome of any such litigation could harm our business.

We may not be able to successfully identify, consummate or integrate acquisitions or to successfully manage the impacts of such transactions on our operations.

Part of our business strategy includes pursuing synergistic acquisitions. We have expanded, and plan to continue to expand, our business by making strategic acquisitions and regularly seeking suitable acquisition targets to enhance our growth. Material acquisitions, dispositions and other strategic transactions involve a number of risks, including: (i) the potential disruption of our ongoing business; (ii) the distraction of management away from the ongoing oversight of our existing business activities; (iii) incurring indebtedness; (iv) the anticipated benefits and cost savings of those transactions not being realized fully, or at all, or taking longer to realize than anticipated; (v) an increase in the scope and complexity of our operations; and (vi) the loss or reduction of control over certain of our assets.

The pursuit of acquisitions may pose certain risks to us. We may not be able to identify acquisition candidates that fit our criteria for growth and profitability. Even if we are able to identify such candidates, we may not be able to acquire them on terms or financing satisfactory to us. We will incur expenses and dedicate attention and resources associated with the review of acquisition opportunities, whether or not we consummate such acquisitions.

Additionally, even if we are able to acquire suitable targets on agreeable terms, we may not be able to successfully integrate their operations with ours. Achieving the anticipated benefits of any acquisition will depend in significant part upon whether we integrate such acquired businesses in an efficient and effective manner. We may not be able to achieve the anticipated operating and cost synergies or long-term strategic benefits of our acquisitions within the anticipated timing or at all. The benefits from any acquisition will be offset by the costs incurred in integrating the businesses and operations. We may also assume liabilities in connection with acquisitions to which we would not otherwise be exposed. An inability to realize any or all of the anticipated synergies or other benefits of an acquisition as well as any delays that may be encountered in the integration process, which may delay the timing of such synergies or other benefits, could have an adverse effect on our business, results of operations and financial condition.

Our failure to meet the continued listing requirements of Nasdaq could result in the delisting of our Common Stock.

Although we regained compliance with Nasdaq’s continued listing requirements in March 2026, we are currently subject to a one-year Discretionary Panel Monitor. If we fail to maintain compliance during the monitoring period, Nasdaq may take steps to delist our common stock. Such a delisting would likely have a negative effect on the price of our common stock and would impair stockholders’ ability to sell or purchase our common stock when they wish to do so, as well as adversely affect our ability to issue additional securities and obtain additional financing in the future.

There can be no assurance that we will be able to regain compliance with the Bid Price Rule, the Timely Filing Requirement, or the Stockholders’ Equity Requirement, or will otherwise be in compliance with other applicable Nasdaq Listing Rules. If we fail to meet the conditions set forth in our compliance plan or if Nasdaq delists our securities from trading for any other reason, we could face significant material adverse consequences, including:

•        a limited availability of market quotations for our securities;

•        reduced liquidity with respect to our securities;

•        a determination that our common stock is a “penny stock” which will require brokers trading in our ordinary shares to adhere to more stringent rules, possibly resulting in a reduced level of trading activity in the secondary trading market for our ordinary shares;

•        a limited amount of news and analyst coverage for our company; and

•        a decreased ability to issue additional securities or obtain additional financing in the future.

Our stock price could be extremely volatile. As a result, shareholders may not be able to re-sell their shares at or above the price they paid for them.

The market price of our common stock may be highly volatile and could be subject to wide fluctuations. Volatility in the market price of our common stock, as well as general economic, market or political conditions, may prevent shareholders from being able to sell their shares at or above the price they paid for their shares and may otherwise negatively affect the liquidity of our common stock. Shareholders may experience a decrease, which could be substantial, in the value of their stock, including decreases unrelated to our operating performance or prospects, and

shareholders could lose part or all of their investment. The price of our common stock has been, and could continue to be, subject to wide fluctuations in response to a number of factors, including those described elsewhere in this Report and others such as:

•        our ability to generate sufficient revenues to achieve profitability and positive cash flow;

•        competition in our industry and our ability to compete effectively;

•        our ability to attract, recruit, retain and develop key personnel and qualified employees;

•        reliance on significant clients and third-party suppliers;

•        our ability to successfully identify and complete acquisitions and effectively integrate those acquisitions into our operations;

•        our actual or anticipated operating and financial results, including how those results vary from the expectations of management, securities analysts and investors;

•        changes in financial estimates or publication of research reports and recommendations by financial analysts or actions taken by rating agencies with respect to us or other industry participants;

•        developments in our business or operations or our industry sectors generally;

•        any future offerings by us of our common stock;

•        any coordinated trading activities or large derivative positions in our common stock, for example, a “short squeeze” (a short squeeze occurs when a number of investors take a short position in a stock and have to buy the borrowed securities to close out the position at a time that other short sellers of the same security also want to close out their positions, resulting in a surge in stock prices, i.e., demand is greater than supply for the stock sold short);

•        legislative or regulatory changes affecting our industry generally or our business and operations specifically;

•        the operating and stock price performance of companies that investors consider to be comparable to us;

•        announcements of strategic developments, acquisitions, restructurings, dispositions, financings and other material events by us or our competitors;

•        actions by our current shareholders, including future sales of common shares by existing shareholders, including our directors and executive officers;

•        proposed or final regulatory changes or developments;

•        anticipated or pending regulatory investigations, proceedings, or litigation that may involve or affect us; and

•        the other factors described under Risk Factors in Part I, Item 1A of this Report.

In response to any one or more of these events, the market price of shares of our common stock could decrease significantly. In the past, securities class action litigation has often been initiated against companies following periods of volatility in their stock price. This type of litigation could result in substantial costs and divert our management’s attention and resources and could also require us to make substantial payments to satisfy judgments or to settle litigation.

Shareholders may be diluted by future issuances of preferred stock or additional common stock in connection with our incentive plans, acquisitions or otherwise; future sales of such shares in the public market, or the expectations that such sales may occur, could lower our stock price.

Our certificate of incorporation authorizes us to issue shares of our common stock and options, rights, warrants and appreciation rights relating to our common stock for the consideration and on the terms and conditions established by our Board in its sole discretion. We could issue a significant number of shares of common stock in the future in

connection with investments or acquisitions. Any of these issuances could dilute our existing shareholders, and such dilution could be significant. Moreover, such dilution could have a material adverse effect on the market price for the shares of our common stock.

The future issuance of shares of preferred stock with voting rights may adversely affect the voting power of the holders of shares of our common stock, either by diluting the voting power of our common stock if the preferred stock votes together with the common stock as a single class, or by giving the holders of any such preferred stock the right to block an action on which they have a separate class vote, even if the action were approved by the holders of our shares of our common stock.

The future issuance of shares of preferred stock with dividend or conversion rights, liquidation preferences or other economic terms favorable to the holders of preferred stock could adversely affect the market price for our common stock by making an investment in the common stock less attractive. For example, investors in the common stock may not wish to purchase common stock at a price above the conversion price of a series of convertible preferred stock because the holders of the preferred stock would effectively be entitled to purchase common stock at the lower conversion price, causing economic dilution to the holders of common stock.

We do not anticipate paying any cash dividends on our common stock in the foreseeable future.

We currently intend to retain our future earnings, if any, for the foreseeable future, to fund the development and growth of our business. We do not intend to pay any dividends to holders of our common stock in the foreseeable future. Any decision to declare and pay dividends in the future will be made at the discretion of our Board taking into account various factors, including our business, operating results and financial condition, current and anticipated cash needs, plans for expansion, any legal or contractual limitations on our ability to pay dividends under our loan agreements or otherwise. As a result, if our Board does not declare and pay dividends, the capital appreciation in the price of our common stock, if any, will be our shareholders only source of gain on an investment in our common stock, and shareholders may have to sell some or all of their common stock to generate cash flow from their investment.

If securities or industry analysts do not publish research or reports about our business, or if they downgrade their recommendations regarding our common stock, its trading price and volume could decline.

We expect the trading market for our common stock to be influenced by the research and reports that industry or securities analysts publish about us, our business or our industry. If no additional securities or industry analysts commence coverage of our company, the trading price for our stock may be negatively impacted. If one or more of our covering analysts cease coverage of our company or fail to publish reports on us regularly, we could lose visibility in the financial markets, which in turn could cause our stock price or trading volume to decline and our common stock to be less liquid. Moreover, if one or more of the analysts who cover us downgrades our stock or publishes inaccurate or unfavorable research about our business, or if our results of operations do not meet their expectations, our stock price could decline.

Taking advantage of the reduced disclosure requirements applicable to “emerging growth companies” may make our common stock less attractive to investors.

We qualify as an “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012 (“JOBS Act”). An emerging growth company may take advantage of certain reduced reporting and other requirements that are otherwise generally applicable to public companies, as described above. We currently intend to take advantage of each of these exemptions. We have elected not to opt out of such extended transition period, which means that when a standard is issued or revised and it has different application dates for public or private companies, we, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make a comparison of our financial statements with the financial statements of a public company that is not an emerging growth company, or the financial statements of an emerging growth company that has opted out of using the extended transition period, difficult or impossible because of the potential differences in accounting standards used. We cannot predict if investors will find our common stock less attractive if we elect to rely on these exemptions, or if taking advantage of these exemptions would result in less active trading or more volatility in the price of our common stock.

Provisions of our certificate of incorporation and bylaws may delay or prevent a take-over that may not be in the best interests of our shareholders.

Provisions of our certificate of incorporation and bylaws may be deemed to have anti-takeover effects, which include when and by whom special meetings of our shareholders may be called, and may delay, defer or prevent a takeover attempt.

In addition, our certificate of incorporation authorizes the issuance of up to 3,000,000 shares of preferred stock with such rights and preferences determined from time to time by our Board. None of our preferred shares are currently issued or outstanding. Our Board may, without shareholder approval, issue preferred shares with dividends, liquidation, conversion, voting or other rights that could adversely affect the voting power or other rights of the holders of our common stock.

The requirements of being a public company may strain our resources, divert management’s attention and affect our ability to attract and retain executive management and qualified Board members.

As a public company, we are subject to the reporting requirements of the Exchange Act, the Sarbanes-Oxley Act, the Dodd-Frank Act, and other applicable securities rules and regulations. Compliance with these rules and regulations involves significant legal and financial compliance costs, may make some activities more difficult, time-consuming or costly and may increase demand on our systems and resources, particularly after we are no longer an “emerging growth company,” as defined in the JOBS Act. The Exchange Act requires, among other things, that we file annual, quarterly and current reports with respect to our business and operating results. The Sarbanes-Oxley Act requires, among other things, that we maintain effective disclosure controls and procedures and internal control over financial reporting. In order to maintain and, if required, improve our disclosure controls and procedures and internal control over financial reporting to meet this standard, significant resources and management oversight may be required. As a result, management’s attention may be diverted from other business concerns, which could adversely affect our business and operating results. We may need to hire more employees in the future or engage outside consultants, which will increase our costs and expenses.

In addition, changing laws, regulations and standards relating to corporate governance and public disclosure are creating uncertainty for public companies, increasing legal and financial compliance costs and making some activities more time consuming. These laws, regulations and standards are subject to varying interpretations, in many cases due to their lack of specificity, and, as a result, their application in practice may evolve over time as new guidance is provided by regulatory and governing bodies. This could result in continuing uncertainty regarding compliance matters and higher costs necessitated by ongoing revisions to disclosure and governance practices. We intend to invest resources to comply with evolving laws, regulations and standards, and this investment may result in increased general and administrative expenses and a diversion of management’s time and attention from revenue-generating activities to compliance activities. If our efforts to comply with new laws, regulations and standards differ from the activities intended by regulatory or governing bodies due to ambiguities related to their application and practice, regulatory authorities may initiate legal proceedings against us, and our business may be adversely affected.

As a result of disclosure of information in this Report and in filings required of a public company, our business and financial condition are highly visible, which may result in threatened or actual litigation, including by competitors and other third parties. If such claims are successful, our business and operating results could be adversely affected, and even if the claims do not result in litigation or are resolved in our favor, these claims, and the time and resources necessary to resolve them, could divert the resources of our management and adversely affect our business and operating results.

We are subject to ongoing regulatory burdens resulting from our public listing.

We continually work with our legal, accounting and financial advisors to identify those areas in which changes should be made to our financial management control systems to manage our obligations as a public company listed on Nasdaq. These areas include corporate governance, corporate controls, disclosure controls and procedures and financial reporting and accounting systems. We have made, and will continue to make, changes in these and other areas, including our internal controls over financial reporting. However, these and other measures that we might take may not be sufficient to allow us to satisfy our obligations as a public company listed on Nasdaq on a timely basis. In addition, compliance with reporting and other requirements applicable to public companies listed on Nasdaq creates

additional costs for us and requires the time and attention of management. The additional costs that we incur, the timing of such costs and the impact that management’s attention to these matters may adversely affect our business and operating results.

We have identified material weaknesses in our internal control over financial reporting. If we fail to develop or maintain an effective system of internal controls, we may not be able to accurately report our financial results and prevent fraud. As a result, current and potential shareholders could lose confidence in our financial statements, which would harm the trading price of our common shares.

Companies that file reports with the SEC, including us, are subject to the requirements of Section 404 of the Sarbanes-Oxley Act of 2002, or SOX 404. SOX 404 requires management to establish and maintain a system of internal control over financial reporting and annual reports on Form 10-K filed under the Exchange Act to contain a report from management assessing the effectiveness of a company’s internal control over financial reporting. Separately, under SOX 404, as amended by the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, public companies that are large accelerated filers or accelerated filers must include in their annual reports on Form 10-K an attestation report of their regular auditors attesting to and reporting on management’s assessment of internal control over financial reporting. Non-accelerated filers and smaller reporting companies, like us, are not required to include an attestation report of their auditors in annual reports.

We are highly dependent on our management team, and the loss of our executive officers or other key employees could harm our ability to implement our strategies, impair our relationships with clients and adversely affect our business, results of operations and growth prospects.

Our success depends, in large degree, on the skills of our management team and our ability to retain, recruit and motivate key officers and employees. Our senior executive leadership team has significant experience, and their knowledge and relationships would be difficult to replace. Leadership changes will occur from time to time, and we cannot predict whether significant resignations will occur or whether we will be able to recruit additional qualified personnel. Competition for senior executives and skilled personnel in the horticulture industry is intense, which means the cost of hiring, paying incentives and retaining skilled personnel may continue to increase.

We need to continue to attract and retain key personnel and to recruit qualified individuals to succeed existing key personnel to ensure the continued growth and successful operation of our business. In addition, as a provider of custom-tailored horticulture solutions, we must attract and retain qualified personnel to continue to grow our business, and competition for such personnel can be intense. Our ability to effectively compete for senior executives and other qualified personnel by offering competitive compensation and benefit arrangements may be restricted by cash flow and other operational restraints. The loss of the services of any senior executive or other key personnel, or the inability to recruit and retain qualified personnel in the future, could have a material adverse effect on our business, financial condition or results of operations. In addition, to attract and retain personnel with appropriate skills and knowledge to support our business, we may offer a variety of benefits, which could reduce our earnings or have a material adverse effect on our business, financial condition or results of operations.

Our insurance may not adequately cover our operating risk.

We have insurance to protect our assets, operations and employees. While we believe our insurance coverage addresses all material risks to which we are exposed and is adequate and customary in our current state of operations, such insurance is subject to coverage limits and exclusions and may not be available for the risks and hazards to which we are exposed. In addition, such insurance may not be adequate to cover our liabilities or may not be generally available in the future or, if available, premiums may not be commercially justifiable. If we were to incur substantial liability and such damages were not covered by insurance or were in excess of policy limits, or if we were to incur such liability at a time when we are not able to obtain liability insurance, our business, results of operations and financial condition could be materially adversely affected.

We may be exposed to currency fluctuations.

Although our revenues and expenses are expected to be predominantly denominated in United States dollars, we may be exposed to currency exchange fluctuations. Recent events in the global financial markets have been coupled with increased volatility in the currency markets. Fluctuations in the exchange rate between the U.S. dollar,

the Canadian dollar, the Euro, and the currency of other regions in which we may operate may have a material adverse effect on our business, financial condition and operating results. We may, in the future, establish a program to hedge a portion of our foreign currency exposure with the objective of minimizing the impact of adverse foreign currency exchange movements. However, even if we develop a hedging program, there can be no assurance that it will effectively mitigate currency risks.

Changes in accounting standards and subjective assumptions, estimates and judgments by management related to complex accounting matters could significantly affect our financial results.

U.S. generally accepted accounting principles (“U.S. GAAP”) and related pronouncements, implementation guidelines and interpretations with regard to a wide variety of matters that are relevant to our business, such as, but not limited to, revenue recognition, stock-based compensation, trade promotions, and income taxes are highly complex and involve many subjective assumptions, estimates and judgments by our management. Changes to these rules or their interpretation or changes in underlying assumptions, estimates or judgments by our management could significantly change our reported results.

Our ability to maintain our reputation is critical to the success of our business, and the failure to do so may materially adversely affect our business and the value of our common stock.

Our reputation is a valuable component of our business. Threats to our reputation can come from many sources, including adverse sentiment about our industry generally, unethical practices, employee misconduct, failure to deliver minimum standards of service or quality, compliance deficiencies, and questionable or fraudulent activities of our clients. Negative publicity regarding our business, employees, or clients, with or without merit, may result in the loss of clients, investors and employees, costly litigation, a decline in revenues and increased governmental regulation. If our reputation is negatively affected, by the actions of our employees or otherwise, our business and, therefore, our operating results and the value of our common stock may be materially adversely affected.

DESCRIPTION OF THE TRANSACTIONS

Merger with Flash Sports and Media, Inc.

On February 17, 2026, urban-gro, Inc., a Delaware corporation entered into a Agreement and Plan of Merger (the “Merger Agreement”) with Flash Sports & Media, Inc., a Delaware corporation and UGRO Merger Sub, Inc., a Delaware corporation and wholly owned subsidiary of the Company, pursuant to which the Company shall acquire Flash by way of a merger of the Merger Sub with and into Flash, with Flash being a wholly owned subsidiary of the Company and the surviving entity in the Merger.

Under the terms of the Merger Agreement, at the closing of the merger (the “Closing”), stockholders of Flash shall receive the right to receive (i) shares of UGRO Common Stock equal to 19.99% of the outstanding shares of UGRO calculated based on the outstanding shares of UGRO immediately prior to the issuance of 1,000,000 shares of Common Stock on January 23, 2026 (adjusted to 40,000 shares following the reverse stock split) as disclosed in the Current Report on Form 8-K filed January 29, 2026, to be issued to stockholders of the Company, pro rata in proportion to their respective stock ownership in the Company, and (ii) shares of UGRO Non-Voting Convertible Preferred Stock to be issued to the stockholders of Flash, pro rata in proportion to their respective stock ownership in Flash, in an aggregate amount such that, upon effectiveness of the conversion of such shares into Common Stock of UGRO, the total number of shares of UGRO Common Stock issuable to the stockholders of the Company (including the shares of UGRO Common Stock issued pursuant to clause (i) above) shall equal a number of shares determined by dividing (A) the agreed equity valuation of Flash as mutually agreed and determined by the parties pursuant to the Merger Agreement, by (B) $3.23, representing the closing price of UGRO Common Stock on February 17, 2026 (the “Reference Price”), with such quotient representing the aggregate number of shares of UGRO Common Stock issuable to the stockholders of Flash on a fully converted basis.

Consulting Agreement

On November 20, 2025, the Company entered into a consulting agreement (the “Consulting Agreement”) with Hudson Global Ventures, LLC (the “Consultant”), pursuant to which the Consultant agreed to provide the Company with business advisory services, guidance on growth strategies, and networking on a non-exclusive basis for a term of three (3) months from the effective date. In consideration for the Consultant’s services, the Company issued 763,018 shares of Common Stock to the Consultant, which shares were fully earned as of the effective date of the Consulting Agreement. The Consulting Agreement further provides that if (i) the merger transaction between the Company and Flash Sports & Media, Inc. is consummated and (ii) the closing price of the Common Stock on the date that is six (6) months from the date of the Consulting Agreement is lower than $0.70, the Company shall pay to the Consultant the “Cash Amount,” which is defined as $500,000 minus the “Share Value” (calculated as such closing price multiplied by the number of shares issued under the Consulting Agreement). In addition, if the Common Stock becomes a “penny stock” as defined in SEC Rule 240.3a51-1, the remaining shares held by the Consultant shall be automatically canceled and extinguished, and the Company shall pay to the Consultant a redemption amount in cash equal to the number of remaining shares multiplied by the closing price of the Common Stock on the date of the Consulting Agreement. After giving effect to the 1-for-25 reverse stock split, 763,018 shares of common stock are equivalent to 30,520 shares of common stock.

March 2026 AHP Transaction

On March 23, 2026, the Company entered into a Securities Purchase Agreement (the “March Purchase Agreement”) with AHP, pursuant to which the Company issued to AHP a Convertible Promissory Note (the “March Note”) and a Common Stock Purchase Warrant (the “March Warrant”).

The March Note has a total principal amount of up to $1,395,000, with a corresponding purchase price of up to $1,260,000, resulting in an original issue discount of up to $135,000. In connection with the funding of the First Tranche, the Holder paid $420,000 of the purchase price, resulting in an outstanding principal amount of $465,000, consisting of the First Tranche amount plus the prorated portion of the original issue discount. The March Note bears a one-time interest charge of twelve percent (12%) on the principal amount with respect to each tranche. The maturity date for each tranche is twelve (12) months from the date the respective portion of the purchase price was funded by the Holder.

The March Note is convertible, at the option of the Holder, into shares of Common Stock at a conversion price equal to the lesser of (i) the Fixed Price of $2.50 per share or (ii) the Market Price, defined as 75% of the average of the three (3) lowest traded prices of the Common Stock on the principal market during the ten (10) Trading Days immediately preceding the respective conversion date. The Holder’s right to convert is subject to a beneficial ownership limitation of 4.99% of the outstanding shares of Common Stock, and an Exchange Cap as defined in the March Purchase Agreement. The Holder may not convert the Note prior to the earlier of (i) the date that is six (6) calendar months after the Issue Date or (ii) the date the Conversion Shares are registered for resale under a registration statement filed by the Company.

In connection with the March Purchase Agreement, the Company issued to AHP the March Warrant to purchase up to 186,000 shares of Common Stock at an initial exercise price of $2.50 per share, exercisable at any time during the five (5) year period commencing on the issuance date. The March Warrant may be exercised on a cash or cashless basis. The exercise of the March Warrant is subject to a beneficial ownership limitation of 4.99% of the outstanding Common Stock.

April 2026 AHP Transaction

On April 7, 2026, the Company entered into a Securities Purchase Agreement (the “April Purchase Agreement”) with AHP, pursuant to which the AHP agreed to purchase, and the Company agreed to issue and sell to the Buyer, a 12% secured promissory note (the “April Note”) in an aggregate principal amount of up to $2,775,000, at an aggregate purchase price of up to $2,525,000, in one or more tranches.

Pursuant to the April Purchase Agreement, AHP funded the first tranche in the original principal amount of $2,225,495.05 (the “First Tranche”) for a purchase price of $2,025,000 (the “Purchase Price”). AHP withheld $25,000 from the Purchase Price to cover the AHP’s legal fees in connection with the First Tranche.

The April Note is convertible into shares of the Company’s common stock, par value $0.001 per share (the “Common Stock”), subject to certain limitations, including a beneficial ownership limitation of 4.99% and an exchange cap, unless the Company obtains stockholder approval as required by applicable Nasdaq rules. The conversion price is equal to the lesser of (i) a fixed price of $36.00 per share (subject to adjustment) and (ii) 80% of the average of the three lowest traded prices of the Common Stock on the Company’s principal market during the ten trading days immediately preceding the applicable conversion date (subject to adjustment).

In connection with the funding of the First Tranche, the Company issued to AHP (i) a Common Stock purchase warrant to purchase up to 154,166 shares of Common Stock at an initial exercise price of $18.00 per share (the “First Warrant”) and (ii) a pre-funded Common Stock purchase warrant to purchase up to 26,000 shares of Common Stock at an initial exercise price of $0.01 per share (the “Second Warrant,” and together with the First Warrant, the “Warrants”). The First Warrant is exercisable for a period ending five (5) years after April 7, 2026, and contains customary provisions regarding, among other things, cashless exercise (in certain circumstances), beneficial ownership limitations and adjustments upon certain corporate events.

The April Purchase Agreement also provides for a potential second tranche funding. Subject to satisfaction of certain conditions, including (among other things) the absence of defaults, compliance with covenants, and the Company’s filing of its Annual Report on Form 10-K for the year ended December 31, 2025 with audited financial statements (the “10-K Filing Condition”), AHP agreed to fund an additional $500,000 purchase price under the April Note (the “Second Tranche”). At the closing of the Second Tranche, the principal amount outstanding under the April Note would increase by $549,504.95 (including the prorated portion of original issue discount), and the accrued interest charge would increase by $65,940.60.

SELLING STOCKHOLDERS

The Common Stock being offered by the Selling Stockholders are those previously issued to the Selling Stockholders, and those issuable to the Selling Stockholders, as applicable, upon conversion of the Preferred Shares, March Warrant, March Note, First April Warrant, Second April Warrant and April Note.

The issuance of shares of Common Stock upon conversion of the Preferred Stock may be subject to limitations under applicable Nasdaq listing rules, including the requirement to obtain stockholder approval prior to issuing shares of Common Stock in excess of 19.99% of the Company’s outstanding Common Stock (the “Exchange Cap”). The number of shares set forth in the second and fourth columns of the table below do not reflect these limitations, as the share amounts have been calculated on a fully converted basis.

PLAN OF DISTRIBUTION

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

•        ordinary brokerage transactions and transactions in which the broker dealer solicits purchasers;

•        block trades in which the broker dealer will attempt to sell the securities as agent but may position and resell a portion of the block as principal to facilitate the transaction;

•        purchases by a broker dealer as principal and resale by the broker dealer for its account;

•        an exchange distribution in accordance with the rules of the applicable exchange;

•        privately negotiated transactions;

•        settlement of short sales effected after the effective date of the registration statement of which this prospectus is a part;

•        in transactions through broker dealers that agree with the Selling Stockholders to sell a specified number of such securities at a stipulated price per security;

•        through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;

•        a combination of any such methods of sale; or

•        any other method permitted pursuant to applicable law.

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

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

To the extent required, this prospectus may be amended or supplemented from time to time to describe a specific plan of distribution. In connection with the sale of the securities or interests therein, the Selling Stockholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the securities in the course of hedging the positions they assume. The Selling Stockholders may also sell securities short and deliver these securities to close out their short positions, or loan or pledge the securities to broker-dealers that in turn may sell these securities. The Selling Stockholders may also enter into option or other transactions with broker-dealers or other financial institutions or create one or more derivative securities which require the delivery to such broker-dealer or other financial institution of securities offered by this prospectus, which securities such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

The Selling Stockholders and any broker-dealers or agents that are involved in selling the securities may be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the securities purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act. Each Selling Stockholder has informed the Company that it does not have any written or oral agreement or understanding, directly or indirectly, with any person to distribute the securities.

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

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

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

Except as described under the section of this prospectus entitled “Description of Capital Stock — Anti-Takeover Effects of Delaware Law and Provisions of Our Amended and Restated Certificate of Incorporation and Bylaws” below, a majority vote of the holders of Common Stock present at a meeting in which a quorum is present is generally required to take action under our certificate of incorporation and bylaws.

The rights, preferences, and privileges of holders of Common Stock are subject to, and may be adversely affected by, the rights of the holders of shares of any series of preferred stock that we may designate and issue in the future.

Anti-Takeover Effects of Delaware Law and Provisions of Our Amended and Restated Certificate of Incorporation and Bylaws

Certain provisions of the Delaware General Corporation Law (the “DGCL”) and of our certificate of incorporation and bylaws effective immediately prior to the completion of this offering could have the effect of delaying, deferring or discouraging another party from acquiring control of us. These provisions, which are summarized below, are expected to discourage certain types of coercive takeover practices and inadequate takeover bids and, as a consequence, they might also inhibit temporary fluctuations in the market price of our Common Stock that often result from actual or rumored hostile takeover attempts. These provisions are also designed in part to encourage anyone seeking to acquire

control of us to first negotiate with our board of directors. These provisions might also have the effect of preventing changes in our board of directors or management. It is possible that these provisions could make it more difficult to accomplish transactions that stockholders might otherwise deem to be in their best interests.

However, we believe that the advantages gained by protecting our ability to negotiate with any unsolicited and potentially unfriendly acquirer outweigh the disadvantages of discouraging such proposals, including those priced above the then-current market value of our Common Stock, because, among other reasons, the negotiation of such proposals could improve their terms.

Delaware Takeover Statute

We are subject to the provisions of Section 203 of the DGCL. In general, Section 203 prohibits a publicly held Delaware corporation from engaging in a “business combination” with an “interested stockholder” for a three-year period following the time that this stockholder becomes an interested stockholder, unless the business combination is approved in a prescribed manner. Under Section 203, a business combination between a corporation and an interested stockholder is prohibited unless it satisfies one of the following conditions:

•        before the stockholder became interested, our board of directors approved either the business combination or the transaction that resulted in the stockholder becoming an interested stockholder;

•        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, excluding for purposes of determining the voting stock outstanding, shares owned by persons who are directors and also officers, and employee stock plans, in some instances, but not the outstanding voting stock owned by the interested stockholder; or

•        at or after the time the stockholder became interested, the business combination was approved by our board of directors and authorized at an annual or special meeting of the stockholders by the affirmative vote of at least two-thirds of the outstanding voting stock that is not owned by the interested stockholder.

Section 203 defines a business combination to include:

•        any merger or consolidation involving the corporation and the interested stockholder;

•        any sale, transfer, lease, pledge, exchange, mortgage or other disposition involving the interested stockholder of 10% or more of the assets of the corporation;

•        subject to exceptions, any transaction that results in the issuance or transfer by the corporation of any stock of the corporation to the interested stockholder;

•        subject to exceptions, any transaction involving the corporation that has the effect of increasing the proportionate share of the stock of any class or series of the corporation beneficially owned by the interested stockholder; or

•        the receipt by the interested stockholder of the benefit of any loans, advances, guarantees, pledges or other financial benefits provided by or through the corporation.

In general, Section 203 defines an interested stockholder as any entity or person beneficially owning 15% or more of the outstanding voting stock of the corporation and any entity or person affiliated with or controlling or controlled by the entity or person.

Provisions of Our Certificate of Incorporation and Bylaws

Our certificate of incorporation and bylaws include a number of provisions that may have the effect of delaying, deferring or discouraging another party from acquiring control of us and encouraging persons considering unsolicited tender offers or other unilateral takeover proposals to negotiate with our board of directors rather than pursue non-negotiated takeover attempts. These provisions include the items described below.

Election of Directors

The election of directors is determined by a plurality of the votes cast by the stockholders present in person or represented by proxy at each annual stockholder meeting and entitled to vote thereon, except that if any annual stockholder meeting will not be held, such election will take place at any stockholders meeting called and held in accordance with the DGCL.

Stockholder Meetings

Our bylaws provide that annual stockholder meetings will be held at a date, time, and place — whether remote or in person — as determined by our board of directors. Any stockholder seeking to bring business before our annual meeting of stockholders, or to nominate candidates for election as directors at our annual meeting of stockholders, must provide written or printed notice of the annual meeting of stockholders stating the place, day and hour of the meeting, and in case of a meeting held by remote communication stating such means, will be delivered not less than ten nor more than 60 calendar days before the date of the meeting, either personally or by mail, to each stockholder of record entitled to vote at such meeting. Only the board of directors may call a special meeting of the stockholders upon delivery of the written notice described above, with such notice also setting forth the purpose(s) for which the meeting has been called. Our bylaws provide that our board of directors may adopt by resolution such rules and regulations for the conduct of stockholders meetings as the board of directors deems appropriate. Except to the extent inconsistent with such rules and regulations as adopted by our board of directors, the chairman of any meeting of the stockholders has the right and authority to prescribe such rules, regulations and procedures and to do all such acts as, in the judgment of such chairman, are appropriate for the proper conduct of the meeting. These rules, regulations, or procedures, may include, without limitation: (a) the establishment of an agenda or order of business for the meeting; (b) the determination of when the polls shall open and close for any given matter to be voted on at the meeting; (c) rules and procedures for maintaining order at the meeting and the safety of those present; (d) limitations on attendance at or participation in the meeting to stockholders of record of the corporation, their duly authorized and constituted proxies or such other persons as the chairman of the meeting shall determine; (e) restrictions on entry to the meeting after the time fixed for the commencement thereof; and (f) limitations on the time allotted to questions or comments by participants.

Amendment to certificate of incorporation and bylaws.

As required by the DGCL, any amendment of our certificate of incorporation must first be approved by a majority of our board of directors, and if required by law, must thereafter be approved by a majority of the outstanding shares entitled to vote on the amendment, and a majority of the outstanding shares of each class entitled to vote thereon as a class, except that the amendment of the provisions relating to stockholder action, directors, limitation of liability and the amendment of our amended and restated certificate of incorporation must be approved by not less than two-thirds of the outstanding shares entitled to vote on the amendment, and not less than two-thirds of the outstanding shares of each class entitled to vote thereon as a class. Our bylaws may be amended by the affirmative vote of a majority vote of the directors then in office or a majority of our stockholders.

Item 14. Indemnification of Directors and Officers.

Subsection (a) of Section 145 of the General Corporation Law of the State of Delaware (referred to as the “DGCL”) empowers a corporation to indemnify any person who was or is a party or who is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation) by reason of the fact that the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with such action, suit or proceeding if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe the person’s conduct was unlawful.

Subsection (b) of Section 145 empowers a corporation to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact that the person acted in any of the capacities set forth above, against expenses (including attorneys’ fees) actually and reasonably incurred by the person in connection with the defense or settlement of such action or suit if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation, except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the Court of Chancery or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper.

Section 145 further provides that to the extent a director or officer of a corporation has been successful on the merits or otherwise in the defense of any action, suit or proceeding referred to in subsections (a) and (b) of Section 145, or in defense of any claim, issue or matter therein, such person shall be indemnified against expenses (including attorneys’ fees) actually and reasonably incurred by such person in connection therewith; that indemnification provided for by Section 145 shall not be deemed exclusive of any other rights to which the indemnified party may be entitled; and the indemnification provided for by Section 145 shall, unless otherwise provided when authorized or ratified, continue as to a person who has ceased to be a director, officer, employee or agent and shall inure to the benefit of such person’s heirs, executors and administrators. Section 145 also empowers the corporation to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against any liability asserted against such person and incurred by such person in any such capacity, or arising out of his status as such, whether or not the corporation would have the power to indemnify such person against such liabilities under Section 145.

Section 102(b)(7) of the DGCL provides that a corporation’s certificate of incorporation may contain a provision eliminating or limiting the personal liability of a director to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, provided that such provision shall not eliminate or limit the liability of a director (i) for any breach of the director’s duty of loyalty to the corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the DGCL or (iv) for any transaction from which the director derived an improper personal benefit.

Our amended and restated certificate of incorporation provides that we shall indemnify our directors and officers, and may indemnify our employees and other agents, to the maximum extent permitted by the DGCL, and our bylaws provide that we shall indemnify directors, officers, employees and other agents to the maximum extent permitted by the DGCL.

In addition, we have entered into indemnification agreements with each of our directors and officers. These agreements require us to indemnify these individuals to the fullest extent permitted under Delaware law against liabilities that may arise by reason of their service to us, and to advance expenses incurred as a result of any proceeding against them as to which they could be indemnified. We also intend to enter into indemnification agreements with our future directors and officers.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to our directors, officers, and controlling persons pursuant to the foregoing provisions, or otherwise, 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. In the event that a claim for indemnification against such liabilities (other than the payment of expenses incurred or paid by a director, officer or controlling person in a successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, we will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to the 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.

Item 15. Recent Sales of Unregistered Securities.

The following information relates to all securities issued or sold by us within the past three years and not registered under the Securities Act.

Grow Hill Default

On October 1, 2024, we entered into an asset-based term Loan Agreement with Grow Hill, LLC (“Grow Hill”) pursuant to which Grow Hill extended to us a secured loan of $2,100,000 with an origination fee of $100,000, which was added to the amount of the loan. The loan is evidenced by a Secured Promissory Note issued by us to Grow Hill. Grow Hill received a security interest in certain of our assets pursuant to a security agreement between us and Grow Hill (the “Security Agreement”), which does not include any assets of our subsidiaries. This note accrues simple interest at an annual rate of fifteen percent (15%). In connection with entering in this loan, the Company issued to Grow Hill a warrant to purchase up to an aggregate of 160,000 shares of the Company’s common stock at an exercise price of $2.50 per share. Such warrant is exercisable immediately, will expire on the five (5) year anniversary of issuance, and is exercisable on a cashless basis at the election of the holder.

On October 14, 2025, we received service of process for a lawsuit filed by Grow Hill against us in the District Court for the City and County of Denver, Colorado (Case No. 2025CV33546) alleging breach of contract and fraud. Pursuant the complaint, Grow Hill stated that we were in default under the Secured Promissory Note due to a failure to timely make payments, and elected to accelerate all amounts due under the Secured Promissory Note, including a default fee equal to 1% of the outstanding principal amount. We are currently investigating available options to resolve the complaint and intends to vigorously defend the allegation of fraud.

As of December 31, 2025, the Company was in default under the Grow Hill Secured Promissory Note. Monthly payments of $87,500 plus interest ceased after the April 2025 payment. The outstanding balance was approximately $1,487,500 at December 31, 2025. Subsequent to year-end, the Company is in discussions for the Grow Hill debt to be acquired by a third party.

The Grow Hill loan agreement contained a covenant requiring the Company to maintain a Receivable Ratio of at least 2.00:1.00, calculated monthly. The Company failed to maintain the required ratio, which constituted an event of default.

On April 20, 2026, the Company entered into certain assignment, forbearance and exchange agreements with Hudson Global Ventures, LLC relating to the Grow Hill indebtedness, as previously disclosed in the Company’s Current Report on Form 8-K filed with the SEC on April 24, 2026. As of the date of this prospectus, the outstanding balance under the Grow Hill loan has been paid in full and the related litigation has been dismissed.

Upon the payment of the settlement proceeds, the parties will enter into a motion to file with the court to dismiss the litigation with prejudice. Such warrant and the shares of common stock underlying this warrant were, and will be, offered and sold in transactions exempt from registration under the Securities Act of 1933, as amended in reliance on Section 4(a)(2) thereof and Rule 506(b) of Regulation D thereunder.

(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 Securities Exchange Act of 1934, as amended (the “Exchange Act”), that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

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

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

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

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

(ii)    Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5) or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii) or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in 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.

(b)    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.

(c)     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.
