**Subject to completion, dated April 8, 2026**

**PRELIMINARY PROSPECTUS**

 **2,290,312 Shares of Common Stock**

This prospectus relates to the resale by the selling stockholders named in this prospectus (the "Selling Stockholders") from time to time of up to 2,290,312 shares of our common stock, par value $0.001 per share (the "Common Stock"), of RenX Enterprises Corp. (the "Company," "we," "our," or "us"). The shares of Common Stock being registered herewith consist of: (i) up to an aggregate of 1,215,048 shares of Common Stock issuable upon the conversion of those certain senior convertible notes in the aggregate principal amount of $6,042,985.39 (the "Notes") that we issued to the Selling Stockholders on February 17, 2026 pursuant to that securities purchase agreement, dated February 12, 2026 (the "Purchase Agreement"), by and between us and the Selling Stockholders, as more fully described in this prospectus, and (ii) up to 1,075,264 shares of Common Stock (the "First Warrant Shares") issuable upon exercise of certain accompanying warrants (the "First Warrants") that were issued to the Selling Stockholders together with the Notes pursuant to the Purchase Agreement.

The 1,215,048 shares of Common Stock issuable upon conversion of the Notes (the "Conversion Shares") assumes the full conversion of the Notes, plus accrued interest in full into Common Stock, at the conversion price of $5.62 per share (assuming the Notes accrued interest at 12% for a period of thirteen (13) months), without giving effect to any default interest or penalties which may accrue thereunder and without regard to any conversion limitations set forth in the Notes. The First Warrants are exercisable immediately upon issuance, have a term of six years from the date of issuance and are exercisable at a price of $3.1188 per share of Common Stock. The Conversion Shares and the First Warrant Shares are collectively referred to as (the "Private Placement Shares").

The Notes and the First Warrants were issued in reliance upon the exemption from the registration requirements in Section 4(a)(2) of the Securities Act of 1933, as amended (the "Securities Act"), and/or Regulation D promulgated thereunder, as applicable. We are registering the Private Placement Shares for resale by the Selling Stockholders.

We are filing this registration statement on Form S-3, of which this prospectus forms a part, to fulfill our contractual obligations to register the resale of the Private Placement Shares by the Selling Stockholders. See "Selling Stockholders" beginning on page 13 of this prospectus for more information about the Selling Stockholders. Our registration of the shares of Common Stock covered by this prospectus does not mean that the Selling Stockholders will offer or sell any of such shares of Common Stock. The Selling Stockholders named in this prospectus, or their donees, pledgees, transferees or other successors-in-interest, may resell the shares of Common Stock covered by this prospectus through public or private transactions at prevailing market prices, at prices related to prevailing market prices or at privately negotiated prices. For additional information on the possible methods of sale that may be used by the Selling Stockholders, you should refer to the section of this prospectus entitled "Plan of Distribution."

The issuance of the shares of Common Stock covered by this prospectus could cause substantial dilution to our existing stockholders. The number of shares covered by this prospectus represents approximately 91% of the number of shares of Common Stock issued and outstanding as of the date of this prospectus. The actual number of shares of Common Stock that we issue to the Selling Stockholders may be less than the aggregate number of shares covered by this prospectus. Please refer to risk factor entitled "*The issuance of all of the shares of Common Stock covered by this prospectus will significantly increase the total number of shares of Common Stock issued and outstanding and thereby cause our existing stockholders to experience substantial dilution*" on page 5 of this prospectus. For additional information regarding the terms of the Notes and the First Warrants, including those terms which may affect the number of Conversion Shares and First Warrant Shares that may be issued to the holders of the Notes and the First Warrants, you should refer to the section of this prospectus entitled "The Private Placement."

We will not receive any of the proceeds from the sale of Common Stock by the Selling Stockholders. However, we will receive proceeds from the exercise of the First Warrants, if the First Warrants are exercised by the Selling Stockholders for cash. We intend to use those proceeds, if any, for general corporate purposes.

Any Private Placement Shares subject to resale hereunder will have been issued by us and acquired by the Selling Stockholders prior to any resale of such shares pursuant to this prospectus.

No underwriter or other person has been engaged to facilitate the sale of the Private Placement Shares in this offering. We will bear all costs, expenses and fees in connection with the registration of the Private Placement Shares. The Selling Stockholders will bear all commissions and discounts, if any, attributable to their respective sales of the Private Placement Shares.

Shares of our Common Stock are traded on the Nasdaq Capital Market ("Nasdaq") under the symbol "RENX." On April 6, 2026, the closing sale price of our Common Stock on Nasdaq was $2.41 per share.

We are an "emerging growth company" and a "smaller reporting company," each as defined under the federal securities laws and, as such, have elected to comply with certain reduced reporting requirements for this prospectus and may elect to do so in future filings. See the sections of this prospectus entitled "Prospectus Summary - Implications of Being an Emerging Growth Company" and "Prospectus Summary – Implications of Being a Smaller Reporting Company."

We may amend or supplement this prospectus from time to time by filing amendments or supplements as required. You should read the entire prospectus and any amendments or supplements carefully before you make an investment decision.

**Investment in our Common Stock involves risk. See "Risk Factors" contained in this prospectus on page 4, under similar headings in our annual and periodic reports filed from time to time with the Securities and Exchange Commission, which are incorporated by reference in this prospectus and in any applicable prospectus supplement. You should carefully read this prospectus and the accompanying prospectus supplement, together with the documents we incorporate by reference, before you invest in our Common Stock.**

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

The date of this prospectus is , 2026.

**PROSPECTUS SUMMARY**

*This summary highlights certain information about us and selected information contained elsewhere in this prospectus and in the documents we incorporate by reference. This summary does not contain all of the information you should consider before investing in our Common Stock. You should read this entire prospectus and the documents incorporated by reference carefully, especially the risks of investing in our Common Stock discussed under and incorporated by reference in "Risk Factors" on page 4 of this prospectus, along with our consolidated financial statements and notes to those consolidated financial statements and the other information incorporated by reference in this prospectus, before making an investment decision.*

On October 8, 2024, we effected a 1-for-20 reverse stock split of our then-outstanding Common Stock (the "2024 Stock Split"). All share and per share amounts set forth in this prospectus from the period prior to the 2024 Stock Split have been retroactively adjusted to reflect the 2024 Stock Split.

On March 26, 2026, we effected a 1-for-20 reverse stock split of our then-outstanding Common Stock (the "2026 Stock Split"). All share and per share amounts set forth in this prospectus from the period prior to the 2026 Stock Split have been retroactively adjusted to reflect the 2026 Stock Split.

**The Company**

RenX Enterprises Corp. is a Delaware corporation, originally formed in 2021 under the name SGB Development Corp., to engage in real property development using purpose-built, prefabricated modules constructed from both wood and steel. From our inception through 2023, our operations primarily focused on the acquisition, entitlement, and development of residential properties in high-growth markets across the United States. These efforts included the direct acquisition of land, strategic investments in real estate entities, and joint venture partnerships targeting green, single-family and multifamily housing projects.

In 2023 and early 2024, we expanded our strategy by investing in real estate-related artificial intelligence ("AI") technologies and entering into additional joint ventures in the Southern Texas market aimed at developing sustainable single-family housing. Due to our shift in focus described below, we are no longer pursuing real estate AI related activities. We also announced plans to monetize our real estate holdings by selling properties where third-party appraisals indicated meaningful value appreciation, with proceeds to be reinvested into our current operations.

In June 2025, we completed our acquisition of Resource Group US Holdings LLC ("Resource Group"), which marked a significant strategic shift in our core business. Resource Group, through its subsidiaries, is a vertically integrated, full-service operator in the engineered soils and organic recycling industry. Its operations center on the transformation of targeted organic green waste materials into environmentally friendly soil and mulch products. Through our subsidiary, Zimmer Equipment Inc. ("ZEI"), we provide comprehensive waste logistics and collection services for our own products as well as for products of third parties through ZEI's owned fleet of high-capacity transportation equipment and third-party contractors engaged by us. ZEI offers year-round collection and disposal services through high-capacity grapple trucks, open-top walking floor trailers, and variable-sized containers serving green waste generators, landscaping companies, golf courses, communities, and municipalities. Resource Group works with ZEI to streamline operations by internalizing certain transportation services, reducing over-the-road mileage, lowering disposal costs, and maximizing efficiency.

We currently operate in three segments: biomass recycling, logistics, and real estate. While our logistics business operated by our subsidiary, ZEI, and our biomass recycling business operated by our subsidiary, Resource Group, are expected to serve as our primary operational focuses going forward, we also currently intend to continue to monetize our legacy real estate assets and joint venture interests.

**Risks Associated with this Offering**

Our business and our ability to implement our business strategy are subject to numerous risks, as more fully described in the section of this prospectus entitled "Risk Factors" and under similarly titled headings of the documents incorporated herein by reference. You should read these risks before you invest in our securities. We may be unable, for many reasons, including those that are beyond our control, to implement our business strategy. In particular, risks associated with this offering include:

● If we fail to comply with the continued listing requirements of Nasdaq, our Common Stock may be delisted and the price of our Common Stock and our ability to access the capital markets could be negatively impacted.

● It is not possible to predict the actual number of shares of Common Stock we will issue upon conversion of the Notes.

● The sale of a substantial amount of our shares in the public market could adversely affect the prevailing market price of our securities.

● The issuance of the shares of Common Stock covered by this prospectus could significantly increase the total number of shares of Common Stock issued and outstanding and thereby cause our existing stockholders to experience substantial dilution.

● Under the Purchase Agreement, we are subject to certain restrictive covenants that may make it difficult to procure additional financing.

● Investors who buy shares at different times will likely pay different prices.

● We have additional securities available for issuance, which, if issued, could adversely affect the rights of the holders of our Common Stock.

● Stockholders may experience significant dilution as a result of potential future financings that we may effect.

● An active trading market for our Common Stock may not be sustained.

● Our share price may be subject to substantial volatility, and stockholders may lose all or a substantial part of their investment.

**Implications of Being an Emerging Growth Company**

We are an "emerging growth company" as defined in the federal securities laws. An emerging growth company may take advantage of specified reduced reporting requirements that are otherwise generally applicable to public companies. As a result:

● we are required to have only two years of audited financial statements and only two years of management's discussion and analysis of financial condition and results of operation in this prospectus;

● we are not required to comply with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory audit firm rotation or a supplement to the auditor's report providing additional information about the audit and financial statements (i.e., an auditor discussion and analysis) compliance with new or revised accounting standards until they are made applicable to private companies;

● we are not required to engage an auditor to provide an attestation to report on our internal control over financial reporting pursuant to Section 404(b) of the Sarbanes-Oxley Act of 2002;

● we are not required to comply with certain disclosure requirements related to executive compensation, such as the requirement to disclose the correlation between executive compensation and performance and the requirement to present a comparison of our Chief Executive Officer's compensation to our median employee compensation; and

● we are not required to submit certain executive compensation matters to stockholder advisory votes, such as "say on pay," "say on frequency" and "say on golden parachute arrangements."

We may take advantage of these reduced reporting and other requirements until the earlier of (i) the last day of the first fiscal year following the fifth anniversary of the completion of this offering; (ii) the last day of the first fiscal year in which we have total annual gross revenue of at least $1.235 billion; (iii) the last day of the fiscal year in which we are deemed to be a "large accelerated filer" as defined in Rule 12b-2 under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), which would occur if the market value of our common stock held by non-affiliates exceeded $700.0 million as of the last business day of the second fiscal quarter of such fiscal year; or (iv) the date on which we have issued more than $1.0 billion in non-convertible debt securities during the prior three-year period.

We have elected to take advantage of certain of the reduced disclosure obligations in this prospectus and the registration statement of which this prospectus is a part, and we may elect to take advantage of other reduced reporting requirements in the future. As a result, the information that we provide to our stockholders may be different than, and not comparable to, information presented by other public reporting companies.

**Implications of Being a Smaller Reporting Company**

We are also a "smaller reporting company" as defined in Rule 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 (1) the market value of our shares held by non-affiliates equals or exceeds $250 million as of the prior June 30th, or (2) our annual revenues equaled or exceeded $100 million during such completed fiscal year and the market value of our shares held by non-affiliates equals or exceeds $700 million as of the prior June 30th. Such reduced disclosure and corporate governance obligations may make it more challenging for investors to analyze our results of operations and financial prospects. We may be a smaller reporting company even after we are no longer an emerging growth company.

**Corporate Information**

We were incorporated in Delaware on February 27, 2021. Our principal executive office is located at 100 Biscayne Blvd., Floor 12, Suite 1201, Miami, Florida 33132, and our phone number is (786) 808-5776. We maintain a website at *www.renxent.com*. The reference to our website is intended to be an inactive textual reference only. The information contained on, or that can be accessed through, our website is not part of this prospectus.

In December 2022, Safe & Green Holdings Corp. ("SG Holdings"), the then owner of 100% of our issued and outstanding securities, announced its plan to separate Safe and Green Development and SG Holdings into two separate publicly traded companies (the "Separation"). To implement the Separation, on September 27, 2023 (the "Distribution Date"), SG Holdings, effected a pro rata distribution to SG Holdings' stockholders of approximately 30% of the outstanding shares of our Common Stock (the "Distribution"). Immediately after the Distribution, we were no longer a wholly owned subsidiary of SG Holdings and SG Holdings held approximately 70% of our issued and outstanding securities. SG Holdings no longer holds any of our issued and outstanding securities. On September 28, 2023, our Common Stock began trading on the Nasdaq Capital Market under the symbol "SGD."

Effective December 19, 2025, we changed our corporate name to RenX Enterprises Corp. and our Common Stock began trading on the Nasdaq Capital Market under the symbol "RENX."

**THE OFFERING**

The Registration Rights Agreement further provides that we shall use commercially reasonable efforts to keep such registration statement effective at all times until all securities covered by such registration statement have been sold or may be sold without volume or manner-of-sale restrictions pursuant to Rule 144 and without the requirement for us to be in compliance with the current public information requirement under Rule 144. |

We will not receive any proceeds from the sale of the Private Placement Shares by the Selling Stockholders (although we may receive proceeds from the exercise of the First Warrants, to the extent such Warrants are exercised for cash by the Selling Stockholders). See "*Use of Proceeds*" in this prospectus. |
| **Risk Factors** | You should read the "Risk Factors" section of this prospectus and in the documents incorporated by reference in this prospectus for a discussion of factors to consider before deciding to purchase shares of our Common Stock. |

**RISK FACTORS**

*Investing in our shares of Common Stock involves a high degree of risk. Before deciding whether to invest in our Common Stock, you should consider carefully the risks and uncertainties described below, together with all of the other information included or incorporated by reference in this prospectus, including the risks and uncertainties discussed under "Risk Factors" in our most recent Annual Report on Form 10-K and our subsequent Quarterly Reports on Form 10-Q, which are incorporated by reference in this prospectus, as well as any updates thereto contained in subsequent filings with the SEC or any free writing prospectus, before deciding whether to purchase our Common Stock in this offering. All of these risk factors are incorporated herein in their entirety. The risks described below and incorporated by reference are material risks currently known, expected or reasonably foreseeable by us. However, the risks described below and incorporated by reference are not the only ones that we face. Additional risks not presently known to us or that we currently deem immaterial may also affect our business, operating results, prospects or financial condition. If any of these risks actually materialize, our business, prospects, financial condition, and results of operations could be seriously harmed. This could cause the trading price of our Common Stock to decline, resulting in a loss of all or part of your investment.

***If we fail to comply with the continued listing requirements of Nasdaq, our Common Stock may be delisted and the price of our Common Stock and our ability to access the capital markets could be negatively impacted.***

 ****

Our Common Stock is currently listed for trading on Nasdaq. We must satisfy Nasdaq's continued listing requirements, including, among other things, a minimum stockholders' equity of $2.5 million and a minimum closing bid price of $1.00 per share or risk delisting, which would have a material adverse effect on our business. A delisting of our Common Stock from Nasdaq could materially reduce the liquidity of our Common Stock and result in a corresponding material reduction in the price of our Common Stock. In addition, delisting could harm our ability to raise capital through alternative financing sources on terms acceptable to us, or at all, and may result in the potential loss of confidence by investors, suppliers, customers and employees and fewer business development opportunities.

On January 26, 2026, we received a letter from Nasdaq notifying us that for the preceding 30 consecutive business days (December 5, 2025 through January 20, 2026), our Common Stock did not maintain a minimum closing bid price of $1.00 per share as required by Nasdaq Listing Rule 5550(a)(2) ("Minimum Bid Price Requirement"). The notice had no immediate effect on the listing or trading of our Common Stock, which continues to trade on the Nasdaq Capital Market under the symbol "RENX." In accordance with Nasdaq Listing Rule 5810(c)(3)(A), we have a compliance period of 180 calendar days, or until July 27, 2026, to regain compliance with Nasdaq Listing Rule 5550(a)(2). On December 8, 2025, our stockholders approved and authorized us to amend our Amended and Restated Certificate of Incorporation, as amended, to effect a reverse stock split at a ratio of 1-for-5 to 1-for-20, and on March 26, 2026, we effected the 1-for-20 reverse stock split of our then-outstanding Common Stock. Nasdaq Listing Rule 5810(c)(3)(A)(iv) states that any listed company that fails to meet the Minimum Bid Price Requirement and has effected a reverse stock split over the prior one-year period, or has effected one or more reverse stock splits over the prior two-year period with a cumulative ratio of 250 shares or more to one, will not be eligible for an automatic 180-day grace compliance period and the Nasdaq Listing Qualifications Department is obligated to immediately issue a delisting determination if it should fail to meet any continued listing requirements. Therefore, if we were to fail to meet any continued listing requirements we would immediately be issued a delisting determination. Further, the Nasdaq rule provides that a company will not be considered to have regained compliance with the minimum bid price requirement if the company takes an action to achieve compliance (such as a reverse split) and that action results in the Company's security falling below the numeric threshold for another listing requirement.

As of April 8, 2026, the closing bid price of our Common Stock has been over $1.00 per share for nine consecutive trading days since we completed the 2026 Stock Split for the purpose of regaining compliance with the Minimum Bid Price Requirement. In order to regain compliance with the Minimum Bid Price Requirement, the closing bid price of our Common Stock must be $1.00 per share or greater for a minimum period of 10 consecutive trading days (which may be subject to extension by Nasdaq, in their discretion) after completion of the 2026 Stock Split. There can be no assurance that we will be able to regain compliance with the Minimum Bid Price Requirement within the applicable compliance period or at all.

Additionally, Nasdaq has recently proposed a new rule change to (i) adopt Listing Rules 5450(a)(3) and 5550(a)(6) to require issuers listed on the Nasdaq Global and Capital Markets, respectively, to maintain a minimum Market Value of Listed Securities (as defined in Nasdaq Listing Rule 5005(a)(23)) of at least $5 million for a period of 30 consecutive business days, and (ii) amend Rule 5810 to suspend trading and immediately delist from Nasdaq securities of issuers that do not satisfy the proposed new requirements, and Rule 5815 to set forth the procedures for requesting a hearing before a Hearings Panel and the scope of the Panel's discretion (collectively, the "Proposed $5 Million MVLS Rule"). As of April 8, 2026, the market value of our listed securities is less than $5 million. If the SEC approves the Proposed $5 Million MVSL Rule and the market value of our listed securities does not meet the $5.0 million requirement as of the date it goes into effect, our securities will be subject to delisting.

 ****

There is no assurance that we will regain and/or maintain compliance with all applicable requirements for continued listing on Nasdaq. If our Common Stock were delisted from Nasdaq, trading of our Common Stock would most likely take place on an over-the-counter market established for unlisted securities, such as the OTCQB or the Pink Market maintained by OTC Markets Group Inc. An investor would likely find it less convenient to sell, or to obtain accurate quotations in seeking to buy, our Common Stock on an over-the-counter market, and many investors would likely not buy or sell our Common Stock due to difficulty in accessing over-the-counter markets, policies preventing them from trading in securities not listed on a national exchange or other reasons. In addition, as a delisted security, our Common Stock would be subject to SEC rules as a "penny stock," which impose additional disclosure requirements on broker-dealers. The regulations relating to penny stocks, coupled with the typically higher cost per trade to the investor of penny stocks due to factors such as broker commissions generally representing a higher percentage of the price of a penny stock than of a higher-priced stock, would further limit the ability of investors to trade in our Common Stock. In addition, delisting could harm our ability to raise capital through alternative financing sources on terms acceptable to us, or at all, and may result in the potential loss of confidence by investors, suppliers, customers and employees and fewer business development opportunities. For these reasons and others, delisting would adversely affect the liquidity, trading volume and price of our Common Stock, causing the value of an investment in us to decrease and having an adverse effect on our business, financial condition and results of operations, including our ability to attract and retain qualified employees and to raise capital.

** *It is not possible to predict the actual number of shares of Common Stock we will issue upon conversion of the Notes.***

 ****

The Selling Stockholders have the option to determine whether the obligations outstanding under the Notes are paid in cash or shares of Common Stock. Accordingly, the actual number of shares of Common Stock that will be issued upon conversion of the Notes, if any, cannot be determined at this time.

 ****

***The sale of a substantial amount of our shares in the public market could adversely affect the prevailing market price of our securities.***

We are registering for resale up to 2,290,312 shares of our Common Stock, which is a significant number of shares compared to the current number of shares of our Common Stock issued and outstanding. Sales of a substantial amount of shares of our Common Stock in the public market, or the perception that such sales might occur, could adversely affect the market price of our Common Stock. The issuance of the Conversion Shares and the First Warrant Shares, for example, is likely to further depress the price of our Common Stock, which could, among other factors, make it more difficult for us to maintain compliance with Nasdaq's continued listing requirements. We cannot predict if and when the Selling Stockholders may sell such shares of our Common Stock in the public markets. Furthermore, in the future, we may issue additional shares of our Common Stock or other equity or debt securities convertible into shares of our Common Stock. Any such issuance could result in substantial dilution to our existing stockholders and could cause the market price of our securities to decline.

***The issuance of the shares of Common Stock covered by this prospectus could significantly increase the total number of shares of Common Stock issued and outstanding and thereby cause our existing stockholders to experience substantial dilution.***

The shares of Common Stock being offered pursuant to this prospectus represent Conversion Shares and First Warrant Shares. As of April 8, 2026, there were 2,507,537 shares of Common Stock issued and outstanding (prior to any deemed issuance of any Conversion Shares or First Warrant Shares). The number of shares covered by this prospectus represents approximately 91% of the number of shares of Common Stock issued and outstanding as of the date of this prospectus. As a result, if we are required to issue the maximum number of Private Placement Shares that are being registered hereunder, an existing stockholder's proportionate interest in us will be substantially diluted. The actual number of shares of Common Stock that we issue to the Selling Stockholders may be less than the aggregate number of shares covered by this prospectus.

 ****

***Under the Purchase Agreement, we are subject to certain restrictive covenants that may make it difficult to procure additional financing.***

The Purchase Agreement contains restrictive covenants which restrict our ability to issue securities or file additional registration statements. If we require additional funding while these restrictive covenants remain in effect, we may be unable to effect a financing transaction on terms acceptable to us, or at all, while also remaining in compliance with the terms of the Purchase Agreement, or we may be forced to seek a waiver from the purchasers party to the Purchase Agreement, which such purchasers are not obligated to grant to us.

***Investors who buy shares at different times will likely pay different prices.***

Investors who purchase Private Placement Shares in this offering at different times will likely pay different prices, and so may experience different levels of dilution and different outcomes in their investment results. The Selling Stockholders may sell such Private Placement Shares at different times and at different prices.

***We have additional securities available for issuance, which, if issued, could adversely affect the rights of the holders of our Common Stock.***

We may from time-to-time issue additional shares of Common Stock or preferred stock. In addition, as opportunities present themselves, we may enter into financing or similar arrangements in the future, including the issuance of debt securities, Common Stock or preferred stock. Any future issuances of Common Stock or securities convertible into Common Stock, would further dilute the percentage ownership of us held by holders of Common Stock. In addition, the issuance of certain securities, may be used as an "anti-takeover" device without further action on the part of our stockholders, and may adversely affect the holders of the Common Stock.

 ***Stockholders may experience significant dilution as a result of potential future financings.***

Purchasers of the Private Placement Shares in this offering, as well as our existing stockholders, will experience significant dilution if we sell additional shares at prices significantly below the price at which they invested. In addition, we may issue additional shares of Common Stock or other equity securities exercisable for shares of Common Stock in connection with, among other things, future acquisitions of additional companies or assets, or under our equity incentive plans, in certain cases without stockholder approval. Our existing stockholders may experience significant dilution if we issue shares of Common Stock in the future at prices below the price at which previous stockholders invested.

Our issuance of additional shares of Common Stock or other Common Stock equivalents would have the following effects:

● our existing stockholders' proportionate ownership interest in us will decrease;

● the relative voting strength of each previously outstanding ordinary share may be diminished; and

● the market price of our Common Stocks may decline.

***An active trading market for our Common Stock may not be sustained.***

Although our Common Stock is listed on Nasdaq, the market for our Common Stock has demonstrated varying levels of trading activity. Furthermore, the current level of trading may not be sustained in the future. The lack of an active market for our Common Stock may impair investors' ability to sell their shares of Common Stock at the time they wish to sell them or at a price that they consider reasonable, may reduce the fair market value of their shares of Common Stock and may impair our ability to raise capital to continue to fund operations by selling shares and may impair our ability to utilize our shares as consideration in any licensing or other collaboration transactions with third parties.

***Our share price may be subject to substantial volatility, and stockholders may lose all or a substantial part of their investment.***

Our Common Stock is currently traded on Nasdaq. There is limited public float, and trading volume historically has been low and sporadic. As a result, the market price for our Common Stock may not necessarily be a reliable indicator of our fair market value. The price at which our Common Stock trades may fluctuate as a result of a number of factors, including the number of shares available for sale in the market, quarterly variations in our operating results, actual or anticipated announcements of new releases by us or competitors, the gain or loss of sources of revenues, changes in the estimates of our operating performance, market conditions in our industry and the economy as a whole.

**THE PRIVATE PLACEMENT**

On February 12, 2026, we entered into a securities purchase agreement (the "Purchase Agreement") with the Selling Stockholders for the issuance and sale in a private placement (the "Private Placement") of Notes in the aggregate principal amount of $6,042,985.39. The Notes bear interest at a rate of 12% per annum, will mature 13 months from the date of issuance, subject to limited extension and, without taking into account any accrued and unpaid interest, are initially convertible, at the option of the holder, into an aggregate of 1,075,264 shares of Common Stock, at a conversion price of $5.62 per share (the "Conversion Price"). In connection with the Private Placement, the Company also issued to the Selling Stockholders warrants (collectively, the "Warrants") to purchase an aggregate of 1,937,598 shares of Common Stock (which is equal to the face value of the Notes divided by the exercise price of the Warrants), consisting of (i) First Warrants to purchase 1,075,264 shares of Common Stock, which are exercisable immediately upon issuance, and (ii) additional warrants (the "Second Warrants") to purchase 862,335 shares of Common Stock, which cannot be exercised by the Selling Stockholders unless and until Stockholder Approval (as defined below) is obtained. The First Warrants have a term of six years from the date of issuance and are exercisable at a price of $3.1188 per share of Common Stock, and the Second Warrants will have a term of six years from the date that Stockholder Approval is obtained and will be exercisable at a price of $3.1188 per share of Common Stock. The shares of Common Stock issuable upon exercise of the Second Warrants (the "Second Warrant Shares") are not being registered for resale in this Offering.

The Private Placement closed on February 17, 2026 (the "Closing Date"). The net proceeds to the Company from the Private Placement were approximately $5.4 million, after deducting placement agent fees and the payment of other offering expenses associated with the offering that were payable by the Company and excluding any deductions for make whole payments made to certain of the investors. The Company intends to use the net proceeds from the Private Placement for working capital purposes.

Dawson James Securities, Inc. ("Dawson James") served as the exclusive placement agent in connection with the Private Placement and was paid (i) a cash fee equal to 7.0% of the aggregate gross proceeds of the Private Placement, and (ii) $50,000 for legal fees and other out-of-pocket expenses.

Set forth below is a summary of the Private Placement transaction and the related agreements. Copies of the related agreements have been filed as exhibits to this registration statement and our Current Report on Form 8-K, filed with the SEC on February 17, 2026. You are encouraged to review the full text of such agreements.

***The Securities Purchase Agreement***

The Purchase Agreement contains restrictive covenants which restrict our ability to issue securities or file additional registration statements. The Purchase Agreement further provides that until the date on which the Notes are no longer outstanding, the Company will be prohibited from effecting or entering into an agreement to effect any issuance by the Company or any of its subsidiaries of Common Stock or common stock equivalents (or a combination of units thereof) involving a Variable Rate Transaction (as defined therein).

Pursuant to the Purchase Agreement, until 12 months after the date on which the Notes are no longer outstanding, upon the Company or any of its subsidiaries issuing any securities, including Common Stock, preferred stock, Indebtedness (as defined in the Purchase Agreement) or options or securities convertible into shares of Common Stock (a "Subsequent Financing"), the Selling Stockholders shall have the right to participate in the Subsequent Financing up to an amount, in the aggregate, equal to 50% of the Subsequent Financing on the same terms, conditions and price provided for in the financing.

The Purchase Agreement contains customary representations, warranties, agreements and conditions to completing future sale transactions, indemnification rights and obligations of the parties. Among other things, each of the Selling Stockholders represented to the Company, that it is an "accredited investor" (as such term is defined in Rule 501(a) of Regulation D under the Securities Act), and the Company sold the securities in reliance upon an exemption from registration contained in Section 4(a)(2) of the Securities Act and/or Regulation D promulgated thereunder.

***Securities Issued***

**The Senior Convertible Notes**

 **

The Notes mature 13 months from their date of issuance (subject to extension under certain circumstances), bear interest at a rate of 12% per annum, and are payable in ten monthly installments in an amount equal to 110% of (i) 1/10<sup>th</sup> of the principal of the Notes (ii) plus accrued interest, with the first installment due and payable on the earlier of 180 days from the Closing Date or 90 days following the date that this registration statement is declared effective by the SEC. The Notes are unsecured and are senior to all other Indebtedness (as such term is defined in the Notes) of the Company and its subsidiaries, with each Note ranking *pari passu* with all other Notes.

The Notes are convertible, at the option of the holder, at any time after the date of issuance, into that number of shares of Common Stock equal to the principal amount of the Notes, plus all accrued and unpaid interest and late charges and any other unpaid amounts, at the Conversion Price of $5.62 per share, subject to adjustment for any stock splits, stock dividends, recapitalizations and similar events. The holders of the Notes are prohibited from converting the Notes into shares of Common Stock if, as a result of such conversion, such holder, together with its affiliates, would beneficially own in excess of 4.99% (or, at the option of the holder, 9.99%) of the total number of shares of Common Stock issued and outstanding immediately after giving effect to such exercise.

The Notes are redeemable by the Company at any time, at the Company's option, in whole or in part, at a redemption price equal to 110% of the sum of the principal amount to be redeemed plus accrued interest, if any.

The Notes contain customary events of default. If an event of default occurs, from and after the occurrence, and during the continuance of, an such event of default, the interest rate of the Notes shall automatically increase to 18% per annum until such event of default is cured. Additionally, if an event of default occurs, the holders of outstanding Notes may, regardless of whether such event of default has been cured, require the Company to redeem all or any portion of the outstanding Notes at a price equal to the greater of (i) the product of (A) the value of the Notes to be redeemed multiplied by (B) 110% and (ii) the product of (X) the value of the Notes to be redeemed, divided by the Conversion Price (the "Conversion Rate"), multiplied by (Y) the product of (1) 110% multiplied by (2) the greatest closing sale price of the Common Stock on any trading day during the period commencing on the date immediately preceding such event of default and ending on the date the Company makes the entire payment.

Pursuant to the Notes, the Company shall not enter into or be a party to a Fundamental Transaction (as such term is defined in the Notes) unless (i) the successor entity assumes in writing all of the obligations under the Notes and the other transaction documents and (ii) the successor entity is a publicly traded corporation whose common stock is quoted on or listed for trading on an eligible market, as set forth in the Notes.

While the Notes are outstanding, subject to certain exempt issuances, if the Company sells, offers or grants any option or right to purchase, or otherwise disposes of or sells any equity security or equity-linked or related security, any convertible securities any preferred stock or other securities, the holders of outstanding Notes shall have the right, in their sole discretion, to require that the Company apply up to 30% of the gross proceeds from such sales or offers to redeem all, or any portion, of the outstanding Notes at a price equal to 110% of the amount of the Note being redeemed.

Without giving effect to any default interest or penalties which may accrue thereunder, assuming the full conversion of the Notes plus accrued interest in full into Common Stock without regard to any conversion limitations set forth in the Notes (assuming the Notes accrued interest at 12% for a period of thirteen (13) months), approximately 1,215,048 shares of Common Stock would be issuable upon conversion, all of which shares are being registered pursuant to this registration statement.

**The Warrants**

*Stockholder Approval*

Pursuant to the Second Warrants, we agreed to file a proxy statement with the SEC within 45 days of the Closing Date (which 45 days has been extended by an additional 28 days) and hold a meeting of stockholders at the earliest practical date after the date following the filing thereof (and in no event later than 90 days after the Closing Date, which 90 days has been extended by an additional 28 days) (the "Stockholder Meeting Deadline") for the purpose of obtaining such approval as may be required under the applicable rules of Nasdaq from our stockholders with respect to the issuance of all of the Second Warrant Shares upon the exercise of the Second Warrants in accordance with their terms (including adjustment provisions set forth therein) (the "Stockholder Approval").

We agreed to use our reasonable best efforts to obtain such Stockholder Approval. If, despite our reasonable best efforts the Stockholder Approval is not obtained on or prior to the Stockholder Meeting Deadline, we are obligated to cause an additional stockholder meeting to be held on or prior to the 90th calendar day following the failure to obtain Stockholder Approval. If, despite the Company's reasonable best efforts the Stockholder Approval is not obtained after such subsequent stockholder meetings, the Company shall cause an additional Stockholder Meeting to be held every 90 days thereafter until such Stockholder Approval is obtained, or the Second Warrants are no longer outstanding, whichever is sooner.

*Exercise Price*

The First Warrants are immediately exercisable upon issuance, have a term of six years from the date of issuance, and are exercisable for shares of Common Stock at a price of $3.1188 per share. The Second Warrants shall become exercisable on such date, if ever, that Stockholder Approval is obtained, have a term of six years from the date of Stockholder Approval, and will be exercisable for shares of Common Stock at a price of $3.1188 per share.

The exercise price and number of shares of Common Stock issuable upon exercise of the Warrants are subject to customary adjustments pursuant to stock dividends, stock splits or similar events.

*Cashless Exercise*

 

In the event there is no effective registration statement registering, or the prospectus contained therein is not available for the resale of the shares of Common Stock issuable upon exercise of the Warrants (the "Warrant Shares"), the Warrants may be exercised, in whole or in part, by means of a "cashless exercise" in which case the holder will be entitled to receive a number of Warrant Shares equal to the quotient obtained by dividing, (x) (A) as applicable, the volume weighted average price ("VWAP") of the Common Stock on the date immediately preceding the exercise date (if the notice of exercise is (1) both executed and delivered on a day that is not a Trading Day (as defined in the Warrant) or (2) both executed and delivered on a Trading Day prior to the opening of "regular trading hours) or the bid price of the Common Stock as of the time of the holder's execution of the applicable notice of exercise (if the notice of exercise is executed during "regular trading hours" on a Trading Day), less the exercise price of the Warrant, multiplied by (B) the number of Warrant Shares that would be issuable upon exercise of the Warrant if the exercise were by means of a cash exercise rather than a cashless exercise, by (y) the price used in (A).

*Fundamental Transaction*

 

If a Fundamental Transaction (as such term is defined in the Warrants) occurs, then the successor entity will succeed to, and be substituted for the Company, and may exercise every right and power that the Company may exercise and will assume all of the Company's obligations under the Warrants with the same effect as if such successor entity had been named in the Warrant itself. If holders of the Common Stock are given a choice as to the securities, cash or property to be received in a fundamental transaction, then the holder shall be given the same choice as to the consideration it receives upon any exercise of the Warrant following such Fundamental Transaction. In certain circumstances, the holder will have the right to receive the Black Scholes Value of the Warrant calculated pursuant to a formula set forth in the Warrants, payable either in cash or in the same type or form of consideration that is being offered and being paid to the holders of the Common Stock as described in the Warrants.

 

*Rights of Holder*

Except as otherwise provided in the Warrants or by virtue of such holder's ownership of shares of Common Stock, the holder of a Warrant does not have the rights or privileges of a holder of the Common Stock, including any voting rights, until the holder exercises the Warrant.

 

*Limitations on Exercise*

The holders of the Warrants are prohibited from exercising the Warrants for shares of Common Stock if, as a result of such conversion, such holder, together with its affiliates, would beneficially own in excess of 4.99% (or, at the option of the holder, 9.99%) of the total number of shares of Common Stock issued and outstanding immediately after giving effect to such exercise.

***The Registration Rights Agreement***

 

In connection with the Private Placement, the Company entered into a registration rights agreement (the "Registration Rights Agreement"), dated February 12, 2026, with the Selling Stockholders, pursuant to which the Company agreed to prepare and file a registration statement with the SEC registering the resale of: (a) all Warrant Shares then issued and issuable upon exercise of the Warrants (assuming on such date the Warrants are exercised in full without regard to any exercise limitations therein), (b) all Conversion Shares then issued and issuable upon conversion of the Notes (assuming on such date the Notes are converted in full without regard to any conversion limitations therein), (c) any additional shares of Common Stock issued and issuable in connection with any anti-dilution provisions in the Warrants and/or the Notes, as applicable (without giving effect to any limitations on exercise set forth in the Warrants and/or the Notes, as applicable) and (d) any securities issued or then issuable upon any stock split, dividend or other distribution, recapitalization or similar event with respect to the foregoing (collectively, the "Registrable Securities") no later than 30 calendar days after the Closing Date (the "Filing Date") and to use its commercially reasonable efforts to have the registration statement declared effective as promptly as possible thereafter, and in any event not more than 45 days following the Closing Date, which 45 days has been extended by an additional 12 days (or 75 days following the Closing Date in the event of a "full review" by the SEC) (the "Effectiveness Date"). If certain of the Company's obligations under the Registration Rights Agreement are not met, the Company is required to pay the Selling Stockholders liquidated damages. The Registration Rights Agreement further provides that the Company shall use commercially reasonable efforts to keep such registration statement effective at all times until all Registrable Securities covered by such registration statement have been sold or may be sold without volume or manner-of-sale restrictions pursuant to Rule 144 and without the requirement for the Company to be in compliance with the current public information requirement under Rule 144. This Registration Statement does not register the resale of the Second Warrant Shares. We will be obligated to file another registration statement to register the Second Warrant Shares within ten days of obtaining Stockholder Approval.

***The Placement Agency Agreement***

Dawson James served as the Company's exclusive placement agent in connection with the Private Placement pursuant to the terms of a placement agency agreement (the "Placement Agency Agreement"), dated February 12, 2026, entered into between the Company and Dawson James. Pursuant to the Placement Agency Agreement, Dawson James is entitled to receive (i) a cash fee equal to 7.0% of the aggregate gross proceeds of the Private Placement, and (ii) up to $50,000 for legal fees and other out-of-pocket expenses.

Pursuant to the Placement Agency Agreement, the directors, officers and 5% stockholders of the Company executed lock-up agreements, pursuant to which they agreed not to offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any shares of capital stock of the Company or any securities convertible into or exercisable or exchangeable for shares of capital stock of the Company until 30 days after the effective date of the Initial Registration Statement (as such term is defined in the Registration Rights Agreement).

**USE OF PROCEEDS**

We will not receive any proceeds from the sale of the Private Placement Shares by the Selling Stockholders. We will, however, receive up to an aggregate of approximately $3.5 million in cash from the exercise of the First Warrants, assuming the exercise in full for cash of all the First Warrants, which we intend to use for working capital and general corporate purposes.

The Selling Stockholders will receive all of the proceeds of the sale of Private Placement Shares offered from time to time pursuant to this prospectus. Accordingly, we will not receive any proceeds from the sale of the Private Placement Shares that may be sold from time to time pursuant to this prospectus. See "Plan of Distribution" elsewhere in this prospectus for more information.

**SELLING STOCKHOLDERS**

The Private Placement Shares being offered by the Selling Stockholders are those issuable to the Selling Stockholders upon conversion of the Notes and exercise of the First Warrants. Included in the Private Placement Shares being offered by the Selling Stockholders are: 1,215,048 shares of Common Stock issuable upon the conversion of the Notes, assuming the conversion of the full $6,042,985.39 in principal plus interest of $785,588 (assuming the Notes accrued interest at 12% for a period of thirteen (13) months); and (ii) 1,075,264 First Warrant Shares issuable upon exercise of First Warrants. The Private Placement Shares being offered by the Selling Stockholders do not include 862,335 Second Warrant Shares issuable upon exercise of Second Warrants, subject to receipt of Stockholder Approval. For additional information regarding the issuances of the Notes and the Warrants, see "The Private Placement," above. We are registering the Private Placement Shares in order to permit the Selling Stockholders to offer the Private Placement Shares for resale from time to time.

Each of the Selling Stockholders entered into a securities purchase agreement with the Company on October 16, 2025, pursuant to which they purchased shares of Series B Convertible Preferred Stock ("Series B Preferred Stock") and warrants from the Company, at a combined purchase price of $25.00 for each shares of Series B Preferred Stock and accompanying warrant, in a private placement transaction, which closed on October 17, 2025. As of February 17, 2026, all shares of Series B Preferred Stock and warrants purchased by the Selling Stockholders in such offering had been converted and exercised, as applicable, and are no longer outstanding. Except for the foregoing and the ownership of the Notes and the Warrants, the Selling Stockholders have not had any material relationship with us within the past three years.

The table below lists the Selling Stockholders and other information regarding the beneficial ownership of the shares of Common Stock by each of the Selling Stockholders. The second column lists the number of shares of Common Stock beneficially owned by each Selling Stockholder, based on its ownership of shares of Common Stock, the Notes, the First Warrants and other outstanding securities convertible or exercisable for shares of Common Stock, as of April 8, 2026, assuming conversion and exercise of the Notes, First Warrants and other outstanding securities convertible or exercisable for shares of Common Stock, as applicable, held by the Selling Stockholders on that date, without regard to any limitations on exercises or conversions. The second column does not include the shares of Common Stock issuable upon exercise of the Second Warrants, the exercise of which is subject to receipt of Stockholder Approval.

The third column lists the shares of Common Stock being offered by this prospectus by the Selling Stockholders. In accordance with the terms of a registration rights agreement entered into with the Selling Stockholders, this prospectus generally covers the resale of the maximum number of shares of Common Stock issuable upon conversion or exercise of the Notes and the First Warrants, as applicable, determined as if the outstanding Notes and First Warrants were converted or exercised in full, as applicable, as of the trading day immediately preceding the date this registration statement was initially filed with the SEC, each as of the trading day immediately preceding the applicable date of determination and all subject to adjustment as provided in the registration right agreement, without regard to any limitations on exercises or conversions.

The fourth column assumes the sale of all of the shares of Common Stock offered by the Selling Stockholders pursuant to this prospectus. Because each Selling Stockholder may dispose of all, none or some portion of their Private Placement Shares, no estimate can be given as to the number of Private Placement Shares that will be beneficially owned by a Selling Stockholder upon termination of this offering. For purposes of the table below, however, we have assumed that after termination of this offering none of the Private Placement Shares covered by this prospectus will be beneficially owned by the Selling Stockholders and further assumed that the Selling Stockholders will not acquire beneficial ownership of any additional shares of our Common Stock during the offering. In addition, the Selling Stockholders may have sold, transferred or otherwise disposed of, or may sell, transfer or otherwise dispose of, at any time and from time to time, the Private Placement Shares in transactions exempt from the registration requirements of the Securities Act after the date on which the information in the table is presented.

Under the terms of the Notes and the First Warrants, a Selling Stockholder may not convert or exercise its applicable Notes or First Warrants to the extent such exercise or conversion, as applicable, would cause such Selling Stockholder, together with its affiliates and attribution parties, to beneficially own a number of shares of Common Stock which would exceed 4.99% (or, at the election of the holder, 9.99%) of our then outstanding Common Stock following such exercise or conversion, as applicable, excluding for purposes of such determination shares of Common Stock issuable upon conversion of the Notes or exercise of the First Warrants which have not been converted or exercised. The number of shares in the second and fourth columns does not reflect this limitation. The Selling Stockholders may sell all, some or none of their shares in this offering. See "Plan of Distribution."

Beneficial ownership is determined in accordance with Rule 13d-3(d) promulgated by the SEC under the Exchange Act, and includes our shares of Common Stock with respect to which the Selling Stockholders have sole or shared voting and investment power. The percentage of our shares of Common Stock beneficially owned by the Selling Stockholders prior to the offering shown in the table below is based on 2,507,537 shares of our Common Stock outstanding on April 8, 2026.

**PLAN OF DISTRIBUTION**

Each Selling Stockholder of the Private Placement Shares and any of their pledgees, assignees and successors-in-interest may, from time to time, sell any or all of their shares of Common Stock covered hereby on the principal trading 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;

● 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.

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).

**Item 15. Indemnification of Directors and Officers.**

Section 145 of the Delaware General Corporation Law (the "DGCL") empowers a corporation to indemnify its directors and officers and to purchase insurance with respect to liability arising out of their capacity or status as directors and officers, provided that the person acted in good faith and in a manner the person reasonably believed to be in our best interests, and, with respect to any criminal action, had no reasonable cause to believe the person's actions were unlawful. The DGCL further provides that the indemnification permitted thereunder shall not be deemed exclusive of any other rights to which the directors and officers may be entitled under the corporation's bylaws, any agreement, a vote of stockholders or otherwise.

Section 102(b)(7) of the DGCL permits a corporation to provide in its certificate of incorporation that a director or officer of the corporation shall not be personally liable to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director or officer, except (i) for any breach of the director's or officer'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) a director for payments of unlawful dividends or unlawful stock repurchases or redemptions; (iv) for any transaction from which the director or officer derived an improper personal benefit; or (v) an officer in any action by or in the right of the corporation.

Our Amended and Restated Certificate of Incorporation, as amended ("Charter"), and Second Amended and Restated Bylaws provide for the indemnification of our directors and officers to the fullest extent permitted under Delaware law.

In addition, as permitted by Delaware law, our Charter includes provisions that eliminate the personal liability of our directors for monetary damages resulting from breaches of certain fiduciary duties as a director, except to the extent such an exemption from liability thereof is not permitted under the DGCL.

As permitted by the DGCL, we have entered into indemnity agreements with each of our directors and executive officers, that require us to indemnify such persons against any and all costs and expenses (including attorneys', witness or other professional fees) actually and reasonably incurred by such persons in connection with any action, suit or proceeding (including derivative actions), whether actual or threatened, to which any such person may be made a party by reason of the fact that such person is or was a director or officer or is or was acting or serving as our officer, director, employee or agent or any of our affiliated enterprises. Under these agreements, we are not required to provide indemnification for certain matters, including:

● indemnification beyond that permitted by the DGCL;

● indemnification for any proceeding with respect to the unlawful payment of remuneration to the director or officer;

● indemnification for certain proceedings involving a final judgment that the director or officer is required to disgorge profits from the purchase or sale of our stock;

● indemnification for proceedings involving a final judgment that the director's or officer's conduct was in bad faith, knowingly fraudulent or deliberately dishonest or constituted willful misconduct or a breach of his or her duty of loyalty, but only to the extent of such specific determination;

● indemnification for proceedings or claims brought by an officer or director against us or any of our directors, officers, employees or agents, except for claims to establish a right of indemnification or proceedings or claims approved by our board of directors or required by law;

● indemnification for settlements the director or officer enters into without our consent; or

● indemnification in violation of any undertaking required by the Securities Act or in any registration statement filed by us.

The indemnification agreements also set forth certain procedures that will apply in the event of a claim for indemnification thereunder.

We have an insurance policy in place that covers our officers and directors with respect to certain liabilities, including liabilities arising under the Securities Act or otherwise.

**Item 16. Exhibits.**

See the Exhibit Index immediately preceding the signature page hereto for a list of exhibits filed as part of this registration statement on Form S-3, which Exhibit Index is incorporated herein by reference.

**Item 17. Undertakings.**

The undersigned Registrant hereby undertakes:

To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) to include any prospectus required by Section 10(a)(3) of the Securities Act;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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 and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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 (i), (ii) and (iii) 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 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, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

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.

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.

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(A) Each prospectus filed by a 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

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

That, for purposes of determining any liability under the Securities Act, each filing of Registrant's annual report pursuant to Section 13(a) or 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.

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 a Registrant of expenses incurred or paid by a director, officer or controlling person of a 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, that 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.

Dear Ladies & Gentlemen:

This opinion is furnished to you in connection with a Registration Statement on Form S-3 (the "Registration Statement") filed with the Securities and Exchange Commission (the "Commission") under the Securities Act of 1933, as amended (the "Securities Act"), which registers the resale by the holders thereof of an aggregate of 2,290,310 shares (the "Shares") of common stock, par value $0.001 per share (the "Common Stock"), of RenX Enterprises Corp., a Delaware corporation (the "Company"), which includes (i) up to an aggregate of 1,215,046 shares of Common Stock issuable upon the conversion of certain senior convertible promissory notes in the aggregate principal amount of $6,042,985.39 (the "Notes") at the conversion price of $5.62 per share (assuming the Notes accrued interest at 12% for a period of thirteen (13) months), without giving effect to any default interest or penalties which may accrue thereunder, and (ii) up to 1,075,264 shares of Common Stock issuable upon the exercise of certain accompanying warrants (the "Warrants"), which Warrants are exercisable immediately upon issuance. The Notes and Warrants were issued and sold to the Selling Stockholders in a private placement offering, pursuant to the terms of that certain Securities Purchase Agreement, dated as of February 12, 2026 (the "Purchase Agreement"), between the Company and the Selling Stockholders. Except as otherwise provided herein, all capitalized terms not otherwise defined herein shall have the meanings ascribed to them in the Purchase Agreement. This opinion is being furnished in accordance with the requirements of Item 601(b)(5) of Regulation S-K under the Securities Act.

In rendering the opinions set forth herein, we have examined originals or copies, certified or otherwise identified to our satisfaction, of (i) the Registration Statement and all exhibits thereto; (ii) the Purchase Agreement; (iii) the form of Notes; (iv) the form of Warrants; (v) resolutions adopted by the Board of Directors of the Company (the "Board"); (vi) the amended and restated certificate of incorporation of the Company, as amended; (vii) the second amended and restated bylaws of the Company; and (vii) such other corporate records, agreements, certificates, including, but not limited to, certificates or comparable documents of public officials and of officers and representatives of the Company, statutes and other instruments and documents as we considered relevant and necessary as a basis for the opinions hereinafter expressed.

In rendering this opinion, we have assumed, without inquiry, (i) the authenticity of all documents submitted to us as originals; (ii) the conformity to the original documents of all documents submitted to us as facsimile, electronic, certified or photostatic copies, and the authenticity of the originals of such copies; (iii) the legal capacity of all natural persons and the genuineness of all signatures on the Registration Statement and all documents submitted to us; and (iv) that the books and records of the Company are maintained in accordance with proper corporate procedures.

The Board of Directors

RenX Enterprises Corp.

April 8, 2026

With respect to the Shares we express no opinion to the extent that future issuances of securities of the Company and/or adjustments to outstanding securities of the Company cause the Notes and/or the Warrants to be exercisable for more shares of Common Stock than the number that remain available for issuance.

Based upon the foregoing, we are of the opinion that the Shares have been duly authorized and, when issued upon the conversion of the Notes in accordance with the terms of the Notes or upon exercise of the Warrants in accordance with the terms of the Warrants, the Shares will be validly issued, fully paid and non-assessable.

The opinions expressed herein are limited exclusively to the General Corporation Law of the State of Delaware (the "DGCL") and applicable provisions of the Delaware Constitution and reported judicial decisions interpreting the DGCL and such provisions of the Delaware Constitution and we have not considered, and express no opinion on, any other laws or the laws of any other jurisdiction.

We hereby consent to the filing of this opinion as Exhibit 5.1 to the Registration Statement and to the reference to our firm under the caption "Legal Matters" in the Registration Statement. In giving our consent, we do not thereby admit that we are in the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the Commission thereunder.
