This summary contains basic information about us and this offering. Because it is a summary, it does not contain all of the information that you should consider before deciding to invest in our securities. Before you decide to invest in our securities, you should read this entire prospectus carefully, any related free writing prospectus that we have authorized for use in connection with the offering, including the information included under the heading titled "Risk Factors."

Overview

We are a media and consumer products company engaged in the design, licensing, marketing, live streaming, and social commerce sales of branded apparel, footwear, accessories, fine jewelry, home goods and other consumer products, and the acquisition of dynamic consumer lifestyle brands. Xcel was founded in 2011 with a vision to reimagine shopping, entertainment, and social media as one thing. Currently, our brand portfolio consists of the following:

●

the Halston, Judith Ripka, and C Wonder brands, which are wholly owned by Xcel;

●

the Tower Hill by Christie Brinkley brand, which is a new co-branded collaboration between Xcel and Christie Brinkley that launched in May 2024;

●

the Trust, Respect, Love by Cesar Millan brand, which is a new co-branded collaboration between Xcel and Cesar Millan that we expect to launch in 2026;

●

GemmaMade, which is a co-branded collaboration between Xcel and baking influencer Gemma Stafford which we expect to launch in 2026;

●

The Off/Duty by Coco Rocha brand which is a new co-branded collaboration between Xcel and Coco Rocha, which is planned to launch in Fall 2026; and

●

Mesa Mia, which is a brand owned by Mexican home influencer Jenny Martinez, and for which Xcel has the television rights and expects to launch in 2026.

Xcel is pioneering a true omni-channel and social commerce sales strategy which includes the promotion and sale of products under its brands through interactive television, digital live-stream shopping, social commerce, brick-and-mortar retailers, and e-commerce channels.

Xcel currently operates in a working-capital light model, with our licensees and/or retail partners responsible for the procurement and sale of inventory. As such, our revenues primarily consist of royalty revenues, and we do not have risk of carrying aged inventory. As a result, fluctuations in product costs and tariffs do not have a direct impact on us, but do impact us indirectly as our royalty revenues are typically based on the net sales and success of our licensees.

Our objective is to build a diversified portfolio of lifestyle consumer products brands through organic growth and the strategic acquisition of new brands. To grow our brands, we are focused on the following primary strategies:

●

licensing of our brands for sale through interactive television (e.g., QVC, HSN, JTV, etc.);

●

licensing of our brands to retailers that sell to the end consumer;

●

licensing our brands to manufacturers and retailers for promotion and distribution through e-commerce, social commerce, live streaming, and traditional brick-and-mortar retail channels; and

●

acquiring additional consumer brands and integrating them into our operating platform, and leveraging our operating infrastructure and distribution relationships.

We believe that Xcel offers a unique value proposition to our retail partners and our licensees for the following reasons:

●

our management team, including our officers' and directors' experience in, and relationships within the industry;

●

our deep knowledge, expertise, and proprietary technology in live streaming and social commerce;

●

our design, sales, marketing, and technology platform that enables us to design trend-right product; and

●

our significant media and internet presence.

Implications of Being a Smaller Reporting Company

We are a "smaller reporting company" as defined in the Exchange Act, and have elected to take advantage of certain of the scaled disclosures available to smaller reporting companies. To the extent that we continue to qualify as a "smaller reporting company" as such term is defined in Rule 12b-2 under the Exchange Act we may take advantage of specified reduced reporting requirements and other burdens that are otherwise applicable generally to other public companies including exemption from compliance with the auditor attestation requirements pursuant to SOX and reduced disclosure about our executive compensation arrangements. We will continue to be a "smaller reporting company" until we have $250 million or more in public float (based on our Common Stock) measured as of the last business day of our most recently completed second fiscal quarter or, in the event we have no public float (based on our Common Stock) or a public float (based on our Common Stock) that is less than $700 million, annual revenues of $100 million or more during the most recently completed fiscal year.

Risk Factors

Investing in our securities involves a high degree of risk. Before deciding whether to invest in our securities, you should consider carefully the risks and uncertainties described below, together with all of the other information included in this prospectus. The risks described below are material risks currently known, expected or reasonably foreseeable by us. However, the risks described below are not the only ones that we face. Additional risks not presently known to us or that we currently deem immaterial may also affect our business, 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 securities to decline, resulting in a loss of all or part of your investment. For more information, see the section entitled "Where You Can Find More Information."

It is not possible to predict the actual number of shares of Common Stock we may sell to White Lion under the Common Stock Purchase Agreement, or the actual gross proceeds resulting from those sales.

Because the purchase price per share to be paid by White Lion for the shares of Common Stock that we may elect to sell to White Lion under the Common Stock Purchase Agreement, if any, will fluctuate based on the market prices of our Common Stock at the time we elect to sell shares to White Lion pursuant to the Common Stock Purchase Agreement, if any, it is not possible for us to predict, as of the date of this prospectus and prior to any such sales, the number of shares of Common Stock that we will sell to White Lion under the Purchase Agreement, the purchase price per share that White Lion will pay for shares purchased from us under the Common Stock Purchase Agreement, or the aggregate gross proceeds that we will receive from those purchases by White Lion under the Common Stock Purchase Agreement.

White Lion may sell the shares of our Common Stock described in this prospectus in a number of different ways and at varying prices. The number of shares of our Common Stock ultimately offered for sale by White Lion is dependent upon the number of shares of Common Stock, if any, we ultimately sell to White Lion under the Common Stock Purchase Agreement.

The terms of the Common Stock Purchase Agreement limit the amount of shares of Common Stock we may issue to White Lion, which may limit our ability to utilize the arrangement to enhance our cash resources.

The Common Stock Purchase Agreement includes restrictions on our ability to sell shares of Common Stock to White Lion, including, subject to specified limitations, if a sale would cause White Lion and its affiliates to beneficially own in excess of 4.99% of the then total outstanding shares of Common Stock, provided that, White Lion may increase this beneficial ownership limitation up to 9.99% at its sole discretion upon 61 days prior written notice to the Company. In addition, under applicable rules of Nasdaq, in no event may we issue or sell to White Lion under the Common Stock Purchase Agreement shares of our Common Stock, including the Commitment Shares, in excess of 1,178,173 shares, which is equal to the Exchange Cap, unless (i) we obtain stockholder approval to issue shares of our Common Stock in excess of the Exchange Cap or (ii) the average price of all shares of Common Stock issued to White Lion under the Common Stock Purchase Agreement (including the Commitment Shares) equals or exceeds $1.36 per share, so that the Exchange Cap limitation would not apply to issuances and sales of Common Stock under the Common Stock Purchase Agreement pursuant to the rules and regulations of Nasdaq.

Accordingly, we cannot guarantee that we will be able to sell all 15 million Purchase Shares in this offering. If we cannot sell the full amount of the shares of Common Stock that White Lion has committed to purchase because of these limitations, we may be required to utilize more costly and time-consuming means of accessing the capital markets, which could materially adversely affect our liquidity and cash position. If we choose to sell more shares of Common Stock than are offered under this prospectus, we must first register for resale under the Securities Act such additional shares of Common Stock.

Table of Contents

The sale or issuance of our Common Stock to White Lion may cause dilution and the sale of the shares of Common Stock by White Lion that it acquires pursuant to the Common Stock Purchase Agreement, or the perception that such sales may occur, could cause the price of our Common Stock to decrease.

On January 21, 2026, we entered into the Common Stock Purchase Agreement with White Lion, pursuant to which White Lion has committed to purchase up to $15.0 million of our Common Stock. On the date hereof, we will issue up to 37,500 Commitment Shares to White Lion as a fee for its commitment to purchase shares of our Common Stock under the Purchase Agreement, for which we will not receive any cash consideration. The shares of our Common Stock that may be issued under the Common Stock Purchase Agreement may be sold by us to White Lion at our sole discretion from time to time during the Commitment Period. The purchase price for the shares that we may sell to White Lion under the Common Stock Purchase Agreement will fluctuate based on the trading price of our Common Stock. Depending on market liquidity at the time, sales of such shares may cause the trading price of our Common Stock to decrease. We generally have the right to control the timing and amount of any future sales of our shares to White Lion. Additional sales of our Common Stock, if any, to White Lion will depend upon market conditions and other factors to be determined by us. We may ultimately decide to sell to White Lion all, some or none of the shares of our Common Stock that are available for us to sell pursuant to the Common Stock Purchase Agreement. If and when we do sell shares to White Lion, after White Lion has acquired the shares, White Lion may resell all, some or none of those shares at any time or from time to time in its discretion. Therefore, sales to White Lion by us could result in substantial dilution to the interests of other holders of our Common Stock. Additionally, the sale of a substantial number of shares of our Common Stock to White Lion, or the anticipation of such sales, could make it more difficult for us to sell equity or equity-related securities in the future at a time and at a price that we might otherwise wish to effect sales.

The Common Stock being registered in this prospectus represent a substantial percentage of our public float and of our outstanding Common Stock, and the sale of such shares could cause the market price of Common Stock to decline significantly.

The Common Stock being registered pursuant to this prospectus represent a substantial percentage of our public float and of our outstanding Common Stock. The number of shares being registered in this prospectus represents approximately 227% of the total Common Stock outstanding as of April 17, 2026 which was 6,014,071 shares of Common Stock. The sale of the securities being registered in this prospectus, or the perception in the market that such sales may occur, could result in a significant decline in the public trading price of our Common Stock.

Resales of our Common Stock in the public market by our stockholders as a result of this offering may cause the market price of our Common Stock to fall.

We are registering Common Stock issuable upon the exercise of the Private Placement Warrants. Sales of substantial amounts 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 new shares of Common Stock could result in resales of our Common Stock by our current stockholders concerned about the potential ownership dilution of their holdings. Furthermore, in the future, we may issue additional shares of Common Stock or other equity or debt securities exercisable or convertible into Common Stock. Any such issuance could result in substantial dilution to our existing stockholders and could cause our stock price to decline.

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

Our Certificate of Incorporation authorizes the issuance of 50,000,000 shares of Common Stock, $0.001 par value per share, and 1,000,000 shares of preferred stock, $0.001 par value per share. In certain circumstances, shares of Common Stock and preferred stock, as well as the awards available for issuance under our equity incentive plans, can be issued by our Board of Directors, without stockholder approval. Any future issuances of such stock would further dilute the percentage ownership of us held by holders of Common Stock and preferred stock. In addition, the issuance of certain securities, including pursuant to the terms of our stockholder rights plan, 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.

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

Investors who purchase 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. Our management will have broad discretion over the use of the proceeds from any cash exercise of the Warrants and Placement Agent Warrants, you may not agree with how we use the proceeds, and the proceeds may not be used in ways that may not enhance our operating results or the price of the Common Stock.

Our management will have broad discretion over the use of proceeds, if any, from this offering resulting from the sale of the Purchase Shares under the Common Stock Purchase Agreement and any cash exercise of Warrants, or Placement Agent Warrants, and we could spend the proceeds from this offering in ways our stockholders may not agree with or that do not yield a favorable return, if at all. We intend to use the net proceeds, if any, from the exercise of the Warrants and Placement Agent Warrants for working capital and general corporate purposes. See "Use of Proceeds" on page 9 of this prospectus for additional detail. However, our use of these proceeds may differ substantially from our current plans. If we do not invest or apply the proceeds from this offering in ways that improve our operating results, we may fail to achieve expected financial results, which could cause our stock price to decline.

Moreover, the Warrants and Placement Agent Warrants permit the exercise of such warrants on a "Cashless" basis. If such warrants are exercised on a cashless basis, we will not receive any proceeds from such exercises.

We do not expect to pay dividends in the foreseeable future. As a result, you must rely on stock appreciation for any return on your investment.

We have never declared or paid cash dividends on the Common Stock and do not anticipate paying cash dividends on the Common Stock in the foreseeable future. Any payment of cash dividends will also depend on our financial condition, results of operations, capital requirements and other factors and will be at the discretion of our board of directors, subject to limitations under applicable law. Accordingly, you will have to rely on capital appreciation, if any, to earn a return on your investment in Common Stock.

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, which such Purchasers are not obligated to grant to us.

Use Of Proceeds

The Selling Stockholders will receive all of the proceeds of the sale of shares of Common Stock offered from time to time pursuant to this prospectus. Accordingly, we will not receive any proceeds from the sale of shares of Common Stock that may be sold from time to time pursuant to this prospectus; however, we will receive proceeds from the cash exercise of the Warrants and Placement Agent Warrants. We may also receive up to $15.0 million aggregate gross proceeds under the Common Stock Purchase Agreement from any sales of shares of our Common Stock we make to White Lion pursuant to the Purchase Agreement after the commencement, assuming that we sell the full amount of our Common Stock that we have the right, but not the obligation to sell to White Lion under the Common Stock Purchase Agreement. We currently intend to use the net proceeds from sales of shares of our Common Stock to White Lion under the Common Stock Purchase Agreement and cash exercises of Warrants and Placement Agent Warrants for working capital and general corporate purposes. We have not determined the amount of net proceeds from such cash exercise, if any, to be used specifically for any particular purposes.

The expected use of net proceeds, if any, from the cash exercise of the Warrants, and Placement Agent Warrants represents our intentions based upon our current plans and business conditions, which could change in the future as our plans and business conditions evolve and change. The amounts and timing of our actual expenditures, specifically with respect to working capital, may vary significantly depending on numerous factors. As a result, our management will retain broad discretion over the allocation of the net proceeds from such cash exercise, if any. We have no current agreements, commitments or understandings for any material acquisitions or licenses of any products, businesses or technologies that are definitive or probable to close.

We will bear the out-of-pocket costs, expenses and fees incurred in connection with the registration of shares of our Common Stock to be sold by the Selling Stockholders pursuant to this prospectus. Other than registration expenses, the Selling Stockholders will bear any underwriting discounts, commissions, placement agent fees or other similar expenses payable with respect to sales of shares of our Common Stock.

DIVIDEND POLICY

We currently intend to retain all available funds and any future earnings to fund the growth and development of our business. We have never declared or paid any cash dividends on our capital stock. We do not intend to pay cash dividends on our Common Stock in the foreseeable future. Investors should not purchase our Common Stock with the expectation of receiving cash dividends.

Any future determination to declare dividends will be made at the discretion of our board of directors and will depend on our financial condition, operating results, capital requirements, general business conditions, and other factors that our board of directors may deem relevant.

DETERMINATION OF THE OFFERING PRICE

The prices at which the shares of Common Stock covered by this prospectus may actually be sold will be determined by the prevailing public market price for shares of our Common Stock or by negotiations between the Selling Stockholders and buyers of our Common Stock in private transactions or as otherwise described in "Plan of Distribution."

DESCRIPTION OF THE WHITE LION TRANSACTION

Common Stock Purchase Agreement

On January 21, 2026, the Company entered into a common stock purchase agreement (the "Common Stock Purchase Agreement") and a registration rights agreement (the "Registration Rights Agreement"), with White Lion Capital, LLC (the "Investor"), pursuant to which White Lion has committed to purchase up to $15.0 million of the Company's Common Stock, par value $0.0001 per share (the "Common Stock"), subject to certain limitations and satisfaction of the conditions set forth in the Common Stock Purchase Agreement.

Under the terms and subject to the conditions set forth in the Common Stock Purchase Agreement, the Company has the right, but not the obligation, to sell to White Lion, and White Lion is obligated to purchase, up to $15.0 million of the Company's Common Stock (the "Purchase Shares"). Such sales of Common Stock by the Company, if any, will be subject to certain limitations specified in the Common Stock Purchase Agreement and may occur from time to time, at the Company's sole discretion, during the 24-month period beginning on the date of the Common Stock Purchase Agreement (the "Commitment Period").

Regular Purchases

During the Commitment Period, the Company may, by written notice (each, a "Regular Purchase Notice"), direct White Lion to purchase shares of Common Stock (each such purchase, a "Regular Purchase" and, the Regular Purchase Date (defined below)), subject to the Regular Purchase share limit. The Regular Purchase share limit shall be equal to 30% of the average daily trading volume of the Common Stock on the Principal Market over the five business days immediately preceding the Regular Purchase Notice. A Regular Purchase Notice shall be deemed delivered on the business day (i) a Regular Purchase Notice is received by 9:00 a.m. New York time by email by White Lion and (ii) the DWAC of the applicable Purchase Shares has been initiated and completed as confirmed by White Lion's designated brokerage account by 9:00 a.m. New York time (the "Regular Purchase Notice Date"). If the applicable Regular Purchase Notice is received after 9:00 a.m. New York time or the DWAC of the applicable Purchase Shares has not been completed as confirmed by White Lion's designated brokerage account by 9:00 a.m. New York time, then the next Business Day shall be the Regular Purchase Notice Date, unless waived by Investor in writing. The purchase price for each Regular Purchase shall mean the average of the three (3) lowest traded prices of the Common Stock on the Regular Purchase Notice Date.

Rapid Purchases

Subject to the terms and conditions of the Common Stock Purchase Agreement, in addition to directing purchases of Purchase Shares pursuant to a Regular Notice, during the Commitment Period, the Company shall also have the right, but not the obligation, to direct White Lion to purchase a number of Purchase Shares by delivering a written notice to White Lion (each, a "Rapid Purchase Notice"). A Rapid Purchase Notice shall be deemed delivered on the business day (i) a Rapid Purchase Notice is received by 1:00 p.m. New York time by email by White Lion and (ii) the DWAC of the applicable Purchase Shares has been initiated and completed as confirmed by White Lion's designated brokerage account by 1:00 p.m. New York time (the "Rapid Purchase Notice Date"). If the applicable Rapid Purchase Notice is received after 1:00 p.m. New York time or the DWAC of the applicable Purchase Shares has not been completed as confirmed by White Lion's designated brokerage account by 1:00 p.m. New York time, then the next business day shall be the Rapid Purchase Notice Date, unless waived by Investor in writing. Each Rapid Purchase Notice may direct White Lion to purchase a number of Purchase Shares not to exceed 30% of the average daily trading volume of the Common Stock on the Principal Market over the five business days immediately preceding the Rapid Purchase Notice (the "Rapid Purchase Share Amount"). The purchase price for each Rapid Purchase (the "Rapid Purchase Price," and each such purchase, a "Rapid Purchase") shall be equal to the average of the two lowest traded prices of the Common Stock during the three hour period following White Lion's written consent of the acceptance of the applicable Rapid Purchase Notice Form by Investor.

VWAP Purchases

In addition to purchases of Purchase Shares as described above, during the Commitment Period, the Company may, by written notice (each, a "VWAP Purchase Notice"), direct White Lion to purchase shares of Common Stock (each such

12

Table of Contents

purchase, a "VWAP Purchase" and, the VWAP Date (as defined below)), subject to the VWAP Purchase share limit. The VWAP Purchase share limit shall be equal to 30% of the average daily trading volume of the Common Stock on the Principal Market over the five business days immediately preceding the VWAP Purchase Notice. A VWAP Purchase Notice shall be deemed delivered on the business day (i) that an applicable VWAP Purchase Notice is received by 9:00 a.m. New York time by email by White Lion and (ii) the DWAC of the applicable Purchase Shares has been initiated and completed as confirmed by White Lion's designated brokerage account by 9:00 a.m. New York time (the "VWAP Purchase Notice Date"). If the applicable VWAP Purchase Notice is received after 9:00 a.m. New York time or the DWAC of the applicable Purchase Shares has not been completed as confirmed by White Lion's designated brokerage account by 9:00 a.m. New York time, then the next business day shall be the VWAP Purchase Notice Date, unless waived by Investor in writing. The purchase price for each VWAP Purchase (the "VWAP Purchase Price") shall be equal to the product of (i) the lowest daily volume weighted average price ("VWAP") of the Common Stock during the two (2) consecutive business days commencing on and including the VWAP Purchase Notice Date and (ii) 97%. For the avoidance of doubt, the VWAP Purchase Notice Date shall be the first business day in the VWAP Purchase Valuation Period.

Other Terms

The Company will control the timing and amount of any sales of Common Stock to White Lion pursuant to the Common Stock Purchase Agreement. White Lion does not have the right to require the Company to sell any shares of Common Stock, but is obligated to purchase shares as directed by the Company, subject to the conditions set forth in the Common Stock Purchase Agreement.

The actual amount and timing of any sales of Common Stock will be determined by the Company at its discretion and will depend on various factors, including, among others, general market conditions, the trading price of the Common Stock, and the Company's assessment of appropriate funding sources for its operations. The net proceeds that the Company may receive under the Common Stock Purchase Agreement will vary based on the frequency of sales and the prices at which shares are sold to White Lion. The Company currently intends to use any proceeds from such sales for working capital and general corporate purposes.

In the case of Regular Purchases, Rapid Purchases and VWAP Purchases, the purchase price per share will be equitably adjusted for any reorganization, recapitalization, non-cash dividend, stock split, reverse stock split or other similar transaction occurring during the business days used to compute the purchase price.

The aggregate number of shares that the Company can sell to White Lion under the Common Stock Purchase Agreement together with the number of Commitment Shares (defined below) is limited to and may not exceed (i) 1,178,173 shares (subject to adjustment as described above), which is equal to 19.99% of the total shares of the Common Stock outstanding immediately prior to the execution of the Common Stock Purchase Agreement (the "Exchange Cap"), unless either of the following conditions is satisfied: (i) the Company obtains stockholder approval to issue Purchase Shares in excess of the Exchange Cap; or (ii) the average price paid for all shares of Common Stock issued under the Purchase Agreement equals or exceeds the lower of: (A) the Nasdaq official closing price of the Common Stock on the trading day immediately preceding the date of the Common Stock Purchase Agreement; and (B) the average official closing price of our Common Stock on Nasdaq for the five consecutive trading days ending on the trading day immediately preceding the date of the Common Stock Purchase Agreement.

In all cases, the Common Stock Purchase Agreement also prohibits the Company from directing White Lion to purchase any shares of Common Stock if those shares, when aggregated with all other shares of Common Stock then beneficially owned by White Lion (as calculated pursuant to Section 13(d) of the Securities Exchange Act of 1934, as amended, and Rule 13d-3 thereunder), would result in White Lion beneficially owning more than 4.99% of the then total outstanding shares of Common Stock, provided that, White Lion may increase this beneficial ownership limitation up to 9.99% at its sole discretion upon 61 days prior written notice to the Company.

The Common Stock Purchase Agreement and the related Registration Rights Agreement impose no restrictions on future financings, rights of first refusal, participation rights, penalties, or liquidated damages, except that while the Common Stock Purchase Agreement remains in effect, the Company is prohibited, without the prior approval of White Lion, from entering into any "equity line" or substantially similar transaction whereby an investor is irrevocably bound to purchase

13

Table of Contents

securities over a period of time from the Company at a price based on the market price of the Common Stock at the time of such purchase; provided, however, that this restriction does not prohibit the issuance of shares of Common Stock pursuant to (i) an "at-the-market offering" by the Company through a registered broker-dealer acting as agent of the Company pursuant to a written agreement between the Company and such registered broker-dealer or (ii) the conversion or exercise of derivative securities where the conversion or exercise price varies based on the market price of the Common Stock. White Lion has agreed not to engage in or effect, directly or indirectly, for its own principal account or for the principal account of any of its affiliates, any short sales of the Common Stock during the term of the Common Stock Purchase Agreement.

In consideration for White Lion's execution and delivery of the Common Stock Purchase Agreement, the Company will issue to White Lion shares of Common Stock valued in an aggregate amount of $37,500 (the "Commitment Shares"). The amount of shares to be issued shall be determined by dividing $37,500 by the closing price of the Common Stock on the business day immediately preceding the day on which the Registration Statement is declared effective by the Securities and Exchange Commission (the "SEC"), provided, however, that the Company shall not issue a number of Commitment Shares in excess of the Exchange Cap. The Commitment Fee will be fully earned and payable on the Commencement Date, regardless of whether White Lion purchases any shares under the Common Stock Purchase Agreement or whether the agreement is later terminated. White Lion shall not resell, on any single business day, an amount of Commitment Shares exceeding 10% of the average daily trading volume of the Common Stock.

The Company has agreed to pay Maxim Group LLC a cash fee equal to 4.0% of the gross proceeds received by the Company from sales of securities to White Lion pursuant to any Regular Purchase, Add-On Purchase, or Intraday Purchase, under an advisory agreement between the Company and Maxim Group LLC.

The Common Stock Purchase Agreement contains customary representations, warranties, conditions and indemnification obligations of both parties. The Company may terminate the Common Stock Purchase Agreement at any time upon written notice without cost or penalty.

Registration Rights Agreement

In connection with the execution of the Common Stock Purchase Agreement, the Company and White Lion entered into the Registration Rights Agreement. Pursuant to the terms of the Registration Rights Agreement, the Company is obligated to: (a) file a registration statement on Form S-1 (the "Registration Statement") with the SEC on or prior to the earlier to occur of (i) 60 days after the date of the agreement, or (ii) the date upon which the Company files the resale registration statement required by the Purchase Agreement entered into by the Company and certain investors on December 17, 2025 covering any shares of Common Stock issued as part of the Commitment Fee and the maximum number of Purchase Shares issuable pursuant to the Common Stock Purchase Agreement (collectively, the "Registrable Securities"); (b) use its commercially reasonable best efforts to have the Registration Statement and any amendment thereto declared effective under the Securities Act of 1933, as amended (the "Securities Act") as soon as practicable after such filing and (c) use its commercially reasonable best efforts to keep such Registration Statement continuously effective under the Securities Act pursuant to Rule 415 promulgated under the Securities Act and available for the resale by White Lion of all of the Registrable Securities covered thereby at all times until the earlier of (i) the date on which White Lion shall have resold all the Registrable Securities covered thereby (ii) the date of termination of the Common Stock Purchase Agreement if as of such termination date White Lion holds no Registrable Securities (or, if applicable, the date on which such securities cease to be Registrable Securities after the date of termination of the Common Stock Purchase Agreement) and (iii) all such securities cease to be Registrable Securities.

DESCRIPTION OF The Private Placement

On December 17, 2025, we entered into the Purchase Agreement with the Purchasers for gross proceeds of approximately $2.05 million. The Purchase Agreement provides for the issuance and sale of: (i) 896,126 shares of the Company's Common Stock, (ii) Pre-Funded Warrants to purchase from the Company a total of 773,929 shares of Common Stock, at an exercise price per share equal to $0.001, and (iii) Warrants to purchase from the Company a total of 835,023 shares of Common Stock, at an exercise price per share equal to $3.00.

The closing of the Private Placement occurred on December 18, 2025 (the "Closing Date"). Robert W. D'Loren, Chairman and Chief Executive Officer of the Company, agreed to purchase 81,466 Shares and 40,733 Warrants for a total purchase price of $100,000. The aggregate net proceeds to the Company from the sale of the Private Placement Shares and Pre-Funded Warrants, after deducting the placement agent fees and other estimated offering expenses payable by the Company, are estimated to be approximately $1.82 million.

Pursuant to the Placement Agency Agreement, dated December 17, 2025, by and between the Company and the Placement Agent, the Placement Agent served as the exclusive placement agent in connection with the Private Placement and received (i) a fee equal to up to 8% of the gross proceeds from the Private Placement Shares and Pre-Funded Warrants sold in the Private Placement, (ii) Placement Agent Warrants to purchase 4% of the aggregate number of Private Placement Shares and Pre-Funded Warrants sold in the Private Placement, for an aggregate of up to 66,802 shares of Common Stock, at an exercise price per share equal to $1.165 per share, and (iii) $50,000 for expenses incurred in the Private Placement.

Pursuant to the terms of the Purchase Agreement, we agreed, subject to certain exceptions, not to issue, enter into any agreement to issue, or announce the issuance or proposed issuance of any shares of Common Stock or Common Stock Equivalents (as defined in the Purchase Agreement) for a period of 60 days after December 17, 2025, the date the Purchase Agreement was signed.

In addition, pursuant to the Purchase Agreement, we agreed to file the Registration Statement with the SEC within 30 days of the Closing Date registering for resale the Private Placement Shares, Warrant Shares, and Pre-Funded Warrant Shares. We will use commercially reasonable efforts to have such Registration Statement declared effective by the SEC no later than the 60 days following the Closing Date (or, in the event of a review by the SEC, the later of (i) 90 days following the Closing Date and (ii) 20 days following the date on which the Company files its Annual Report on Form 10-K for the year ending December 31, 2025) and use commercially reasonable efforts to keep such Registration Statement effective at all times until the earlier of (i) such time as no Purchaser owns any Shares, Warrant Shares, or Pre-Funded Warrant Shares issuable upon exercise thereof and (ii) such time as all Purchasers are eligible to resell all Shares, Warrant Shares, and Pre-Funded Warrant Shares pursuant to Rule 144 without compliance by the Company with the current public information requirement of Rule 144.

Warrants

The Warrants have an exercise price of $3.00 per share. The Warrants are exercisable immediately upon issuance and expire on December 18, 2030.

The exercise price of the Warrants, and the number of Warrant Shares, will be subject to adjustment in the event of any stock dividend or split, recapitalization, reorganization or similar transaction, as described in the Warrants.

Holders of the Warrants may not exercise any portion of the Warrants to the extent they would own more than 4.99% (or, or 9.99%, as elected by the holder) of the outstanding common shares immediately after exercise, except that upon at least 61 days' prior notice from the holder to us, the holder may increase the amount of ownership of outstanding stock after exercising the Warrants up to 19.99% of the number of shares of our common shares outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the Warrants.

In the event of a Fundamental Transaction (as such term is defined in the Warrants), the holder has the right to receive, upon exercise of the Warrant, the same amount and kind of securities, cash or property as it would have been entitled to receive upon the occurrence of such Fundamental Transaction if it had been, immediately prior to such Fundamental

Table of Contents

Transaction, the holder of the number of Warrant Shares then issuable upon exercise in full of the Warrant (including any Distributions or Purchase Rights then held in abeyance pursuant to Sections 9(b) or 9(c) in the Warrants) without regard to any limitations on exercise contained herein (the "Alternate Consideration"). If holders of Common Stock are given any choice as to the securities, cash or property to be received in a Fundamental Transaction, then the holder will be given the same choice as to the Alternate Consideration it received upon any exercise of the Warrant following such Fundamental Transaction. The Company will not effect any Fundamental Transaction in which the Company is not the surviving entity or the Alternate Consideration includes securities of another person unless (i) the Alternate Consideration is solely in the form of cash and the Company provides for the simultaneous "cashless exercise" of the Warrants pursuant to Section 10 of the Warrants or (ii) prior to or simultaneously with the consummation thereof, any successor to the Company, surviving entity or other Person (including any purchaser of assets of the Company) assumes the obligation to deliver to the holder such Alternate Consideration as, in accordance with the foregoing provisions, the holder may be entitled to receive, and the other obligations under the Warrant. These provisions will similarly apply to subsequent transactions analogous to a Fundamental Transaction type. If the Company undertakes a Fundamental Transaction in which the Company is not the surviving entity and the Alternate Consideration includes securities of another person, then the Company will provide that, prior to or simultaneously with the consummation of such Fundamental Transaction, any successor to the Company, surviving entity or other person (including any purchaser of assets of the Company) will assume the obligation to deliver to the holder such Alternate Consideration as the holder is entitled to receive in accordance with the foregoing provisions, and to assume the other obligations under the Warrant. These provisions similarly apply to subsequent transactions analogous to a Fundamental Transaction type.

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 will not have the rights or privileges of a holder of Common Stock, including any voting rights, until the holder exercises such warrant.

The foregoing does not purport to be a complete description of the Warrants and is qualified in its entirety by reference to the full text of such documents, which are filed as exhibits to the registration statement of which this prospectus forms a part.

Pre-Funded Warrants

The Pre-Funded Warrants have an exercise price of $0.001 per share. The Pre-Funded Warrants are exercisable immediately upon issuance and will not expire.

The exercise price of the Pre-Funded Warrants, and the number of Pre-Funded Warrant Shares, will be subject to adjustment in the event of any stock dividend or split, recapitalization, reorganization or similar transaction, as described in the Pre-Funded Warrants.

The holder may, in its sole discretion, elect to exercise the Pre-Funded Warrants through a cashless exercise, in which case the holder would receive upon such exercise the net number of shares of Common Stock determined according to the formula set forth in the Warrants.

Holders of the Pre-Funded Warrants may not exercise any portion of the Pre-Funded Warrants to the extent they would own more than 4.99% (or 9.99%, as elected by the holder) of the outstanding common shares immediately after exercise, except that upon at least 61 days' prior notice from the holder to us, the holder may increase the amount of ownership of outstanding stock after exercising the Pre-Funded Warrants up to 19.99% of the number of shares of our common shares outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the Pre-Funded Warrants.

In the event of a Fundamental Transaction (as such term is defined in the Pre-Funded Warrants), the holder has the right to receive, upon exercise of the Pre-Funded Warrant, the Alternate Consideration. If holders of Common Stock are given any choice as to the securities, cash or property to be received in a Fundamental Transaction, then the holder will be given the same choice as to the Alternate Consideration it received upon any exercise of the Pre-Funded Warrant following such Fundamental Transaction. The Company will not effect any Fundamental Transaction in which the Company is not the surviving entity or the Alternate Consideration includes securities of another person unless (i) the Alternate Consideration

16

Table of Contents

is solely in the form of cash and the Company provides for the simultaneous "cashless exercise" of the Pre-Funded Warrant pursuant to Section 10 of the Pre-Funded Warrant or (ii) prior to or simultaneously with the consummation thereof, any successor to the Company, surviving entity or other person (including any purchaser of assets of the Company) assumes the obligation to deliver to the holder such Alternate Consideration as, in accordance with the foregoing provisions, the holder may be entitled to receive, and the other obligations under the Pre-Funded Warrant. These provisions will similarly apply to subsequent transactions analogous to a Fundamental Transaction type. If the Company undertakes a Fundamental Transaction in which the Company is not the surviving entity and the Alternate Consideration includes securities of another person, then the Company will provide that, prior to or simultaneously with the consummation of such Fundamental Transaction, any successor to the Company, surviving entity or other person (including any purchaser of assets of the Company) assumes the obligation to deliver to the holder such Alternate Consideration as the holder is entitled to receive in accordance with the foregoing provisions, and to assume the other obligations under the Pre-Funded Warrant. These provisions similarly apply to subsequent transactions analogous to a Fundamental Transaction type.

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

The foregoing does not purport to be a complete description of the Pre-Funded Warrants and is qualified in its entirety by reference to the full text of such documents, which are filed as exhibits to the registration statement of which this prospectus forms a part.

Placement Agent Warrants

The Placement Agent Warrants have an exercise price of $1.165 per share and are otherwise identical to the Warrants.

DESCRIPTION OF OUR CAPITAL STOCK

We are registering for resale 13,628,865 shares of our Common Stock.

As of the date of this prospectus, our certificate of incorporation authorizes us to issue up to 50,000,000 shares of Common Stock, $0.001 par value per share, and 1,000,000 shares of preferred stock, $0.001 par value per share. As of April 17, 2026, 6,014,071 shares of Common Stock were outstanding and no shares of preferred stock were outstanding.

The following summary describes certain applicable provisions of Delaware law and the material terms of our capital stock. The description of our capital stock is qualified by reference to our certificate of incorporation and our bylaws.

Common Stock

Voting Rights. Holders of our Common Stock are entitled to one vote per share on all matters submitted to a vote of the stockholders, including the election of directors, and subject to any contractual agreement entered into by any holder of shares. Generally, all matters to be voted on by stockholders must be approved by a majority of the votes entitled to be cast by all shares of our Common Stock that are present in person or represented by proxy. Holders of our Common Stock representing a majority of our capital stock issued, outstanding, and entitled to vote, represented in person or by proxy, are necessary to constitute a quorum at any meeting of our stockholders. A vote by the holders of a majority of our outstanding shares is required to effectuate certain fundamental corporate changes such as liquidation, merger or an amendment to our certificate of incorporation. Our certificate of incorporation does not provide for cumulative voting in the election of directors.

Dividends. The holders of shares of our Common Stock will be entitled to such cash dividends as may be declared from time to time by our board of directors from funds available, therefore.

Liquidation Rights. Upon liquidation, dissolution, or winding up, the holders of shares of our Common Stock will be entitled to receive pro rata all remaining assets available for distribution to such holders, after payment of liabilities and after provision has been made for each class of stock, if any, having preference over the Common Stock.

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

Preemptive or Similar Rights. Holders of our Common Stock have no preemptive rights and no conversion rights, and there are no redemption provisions applicable to our Common Stock.

Merger or Consolidation: In the event of any merger or consolidation with or into another company in connection with which shares of our Common Stock are converted into or exchangeable for shares of stock, other securities, or property (including cash), all holders of our Common Stock will be entitled to receive the same kind and amount of shares of stock and other securities and property (including cash).

Reverse Stock Split

We effected a reverse stock split of our outstanding Common Stock at a ratio of 1-for-10 shares, effected on March 25, 2025.

Unless otherwise indicated, the share amounts and per share prices, and the conversion or exercise prices of and the number of shares issuable under our outstanding securities exercisable for Common Stock, in this prospectus have been adjusted to reflect the Reverse Stock Split.

Anti-Takeover Effects of Our Charter Documents and Some Provisions of Delaware Law

Delaware Law

We are incorporated in the State of Delaware. As a result, we are subject to Section 203 of the Delaware General Corporation Law, which prohibits a Delaware corporation from engaging in any business combination with any interested stockholder for a period of three years after the time that such stockholder became an interested stockholder, with the following exceptions:

●

before such time, the board of directors of the corporation approved either the business combination or the transaction that resulted in the stockholder becoming an interested stockholder;

●

upon consummation of the transaction which 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 (but not the outstanding voting stock owned by the interested stockholder) those shares owned (1) by persons who are directors and also officers and (2) employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or

●

at or subsequent to such time, the business combination is approved by the board of directors and authorized at an annual or special meeting of the stockholders, and not by written consent, by the affirmative vote of at least 66 2/3% of the outstanding voting stock that is not owned by the interested stockholder.

In general, Section 203 defines a "business combination" to include the following:

●

any merger or consolidation involving the corporation or a direct or indirect majority-owned subsidiary of the corporation and the interested stockholder;

●

any sale, lease, mortgage, pledge transfer, or other disposition of the assets of the corporation or direct or indirect majority-owned a subsidiary of the corporation to or with the interested stockholder, which assets have an aggregate value equal to 10% or more of the fair value of the assets on a consolidated basis or the aggregate market value of the outstanding stock of the corporation;

18

Table of Contents

●

subject to certain exceptions, any transaction that results in the issuance or transfer by the corporation or a direct or indirect majority-owned subsidiary of the corporation of any stock of the corporation or subsidiary to the interested stockholder;

●

any transaction involving the corporation or direct or indirect majority-owned subsidiary of the corporation that has the effect of increasing the proportionate share of the stock or any class or series of the corporation or the subsidiary 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 by or through the corporation or direct or indirect majority-owned subsidiary of the corporation.

In general, Section 203 defines an "interested stockholder" as an entity or person (other than the corporation any direct or indirect majority-owned subsidiary of the corporation) who, together with the person's affiliates and associates, beneficially owns, 15% or more of the outstanding voting stock of the corporation. A Delaware corporation may "opt out" of these provisions with an express provision in its certificate of incorporation. Since we have not opted out of Section 203, Section 203 may discourage, delay or prevent mergers or other takeover or change of control attempts of us.

Certificate of Incorporation and Bylaws

Our certificate of incorporation provides for our board of directors to be elected at each annual meeting of our stockholders. Because our stockholders do not have cumulative voting rights, stockholders holding a majority of the shares of Common Stock outstanding are able to elect all of our directors. Our bylaws also provide that directors may be removed by the stockholders only for cause upon the vote of 66 2/3% of the shares then entitled to vote at an election of directors. Furthermore, the authorized number of directors may be changed only by resolution of the board of directors, and vacancies and newly created directorships on the board of directors may, except as otherwise required by law or determined by the board, only be filled by a majority vote of the directors then serving on the board, even though less than a quorum.

Our certificate of incorporation, as amended, authorizes our board of directors to establish one or more series of preferred stock. Unless required by law or by any stock exchange on which our Common Stock is listed, the authorized shares of preferred stock will be available for issuance without further action by stockholders. Our board of directors is able to determine the designations, powers, and relative rights, privileges, preferences and other terms, including terms relating to dividend rates, redemption rates, liquidation preferences and voting, sinking fund and conversion or other rights on, a series of preferred stock.

Our bylaws provide that any action required by the General Corporation Law to be taken at any annual or special meeting of stockholders, or any action which may be taken at any annual or special meeting of stockholders, may be taken without a meeting, if a consent in writing, setting forth the action so taken, shall be signed by the holders of outstanding stock having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares entitled to vote thereon were present and voted. Our bylaws also provide that special meetings may be called by a majority of the whole board or by any officer instructed by a majority of the whole board to call the meeting.

Our bylaws provide that stockholders seeking to present proposals before a meeting of stockholders to nominate candidates for election as directors at a meeting of stockholders must comply with the notice provisions set forth in the bylaws, including, but not limited to, providing timely notice in proper written form to the Secretary.

Our bylaws provide that, except as otherwise provided by the General Corporate Law or the certificate of incorporation, any amendment to, repeal of, or adoption of any provisions inconsistent with these Bylaws, which has not previously received the approval of the Board, shall require for adoption the affirmative vote of the holders of a majority of the issued and outstanding shares present in person or represented by proxy at a meeting of stockholders and entitled to vote thereat. Our bylaws further provide that many of the provisions require for adoption the affirmative vote of the holders of not less than two-thirds of the issued and outstanding shares entitled to vote at a duly called and convened annual or special meeting of stockholders.

The combination of these provisions makes it more difficult for our existing stockholders to replace our board of directors as well as for another party to obtain control of us by replacing our board of directors. Since our board of directors has the power to retain and discharge our officers, these provisions could also make it more difficult for existing stockholders or

19

Table of Contents

another party to effect a change in management. In addition, the authorization of undesignated preferred stock makes it possible for our board of directors to issue preferred stock with voting or other rights or preferences that could impede the success of any attempt to change control of the Company.

These provisions are intended to enhance the likelihood of continued stability in the composition of our board of directors and its policies and to discourage coercive takeover practices and inadequate takeover bids. These provisions are also designed to reduce our vulnerability to hostile takeovers and to discourage certain tactics that may be used in proxy fights. However, such provisions could have the effect of discouraging others from making tender offers for our shares and may have the effect of delaying changes in our control or management.

Transfer Agent and Registrar

The transfer agent and registrar for our Common Stock is Continental Stock Transfer & Trust Company. The transfer agent's address is 1 State Street, 30th Floor, New York, New York 10004 and the transfer agent's telephone number is (800) 509-5586.

Howard Brous, the designee of Wellington, has not had any relationship with us during the past three years other than through their affiliation with Wellington.

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. Beneficial ownership is determined in accordance with the rules of the SEC and includes voting or investment power with respect to shares of our Common Stock or if a person has the right to acquire beneficial ownership of our Common Stock within 60 days.

Unless otherwise indicated below, to our knowledge, the Selling Stockholders named in the table below have sole voting and investment power with respect to the shares of Common Stock beneficially owned by them. The number of shares of Common Stock disclosed as beneficially owned in the table below includes (i) all shares of our Common Stock held by such Selling Stockholder as of April 17, 2026, and (ii) all shares of our Common Stock issuable to such Selling Stockholder upon the exercise in full of the Warrants, Pre-Funded Warrants and/or Placement Agent Warrants, without regard to any limitations on exercise of the Warrants, Pre-Funded Warrants and/or Placement Agent Warrants.

The column in the table below titled "Number of Shares of Common Stock Beneficially Owned Prior to Offering" lists the number of shares of Common Stock beneficially owned by the Selling Stockholders, based on their respective ownership of shares of our Common Stock and the Warrants, Pre-Funded Warrants and/or Placement Agent Warrants, as of April 17, 2026, assuming exercise in full of the Warrants, Pre-Funded Warrants and/or Placement Agent Warrants, as the case may be, held by the Selling Stockholders on that date, without regard to any limitations on exercises.

Under the terms of the Warrants and Pre-Funded Warrants, the Selling Stockholders in the Private Placement may not exercise the Warrants to the extent such exercise would cause such Selling Stockholder, together with its affiliates and attribution parties, to beneficially own a number of shares of Common Stock that would exceed 4.9% (9.9% in the case of Potomac Capital Partners V, LP, Maz Partners, LP and Jeff Yokuty) of our then outstanding Common Stock following such exercise, excluding for purposes of such determination shares of Common Stock issuable upon exercise of such Warrants which have not been exercised. The number of shares in the second and third columns do not reflect this limitation. The Selling Stockholders may sell all, some or none of their shares in this offering.

Yash Thukral, Sam Yaffa, and Nathan Yee are the managing principals of White Lion Capital, each of whom may be deemed to have sole voting control and investment discretion over securities beneficially owned directly or indirectly by White Lion Capital. We have been advised that White Lion Capital is not a member of the Financial Industry Regulatory Authority, or FINRA, or an independent broker-dealer.

Thukral, Yaffa, and Yee as to beneficial ownership of the securities beneficially owned directly or indirectly by White Lion Capital.

Represents the Commitment Shares that are issuable upon the date of this prospectus. We have excluded from the number of shares of our Common Stock beneficially owned prior to the offering all of the 11,019,485 shares of our Common Stock that we may issue and sell to White Lion pursuant to the Common Stock Purchase Agreement from and after the Commencement Date that are being registered for resale under the registration statement that includes this prospectus, because the issuance and sale of such shares to White Lion under the Common Stock Purchase Agreement is solely at our discretion and is subject to certain conditions, the satisfaction of all of which are outside of White Lion's control, including the registration statement that includes this prospectus becoming and remaining effective under the Securities Act.

The number of shares ultimately offered for resale by White Lion is dependent upon the number of shares we sell to White Lion under the Common Stock Purchase Agreement. Additionally, under applicable Nasdaq rules, in no event may we issue or sell to White Lion under the Common Stock Purchase Agreement shares of our Common Stock in excess of 1,202,213 shares (including the Commitment Shares), which represents 19.99% of the shares of our Common Stock outstanding (based on 6,014,071 shares outstanding immediately prior to the execution of the Common Stock Purchase Agreement), unless (i) we obtain stockholder approval to issue shares of our Common Stock in excess of the Exchange Cap or (ii) the average price of all applicable sales of our Common Stock to White Lion under the Common Stock Purchase Agreement equals or exceeds $1.36 per share so that the Exchange Cap limitation would not apply to issuances and sales of Common Stock under the Common Stock Purchase Agreement pursuant to the rules and regulations of Nasdaq.

PLAN OF DISTRIBUTION

Each Selling Stockholder of the securities and any of its 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. The Selling Stockholders 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 us that it

does not have any written or oral agreement or understanding, directly or indirectly, with any person to distribute the securities.

We are required to pay certain fees and expenses incurred by us incident to the registration of the securities.

We agreed to keep this prospectus effective until the date on which the Warrants, Pre-Funded Warrants, Placement Agent Warrants, Warrant Shares, Pre-Funded Warrant Shares, and Placement Agent Warrant Shares have been sold. 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 13. Other Expenses of Issuance and Distribution.

The following table sets forth the estimated costs and expenses, payable by the Company, in connection with the sale and distribution of the securities being registered. All amounts are estimates except the SEC registration fee.

​

Item 14. Indemnification of Directors and Officers.

The Registrant is incorporated under the laws of the State of Delaware. Section 145 of the Delaware General Corporation Law 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 Delaware General Corporation Law 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. The certificate of incorporation of the Registrant provides for the indemnification of the Registrant's directors and officers to the fullest extent permitted under the Delaware General Corporation Law. In addition, the bylaws of the Registrant require the Registrant to fully indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding (whether civil, criminal, administrative or investigative) by reason of the fact that such person is or was a director or officer of the Registrant, or is or was a director or officer of the Registrant serving at the Registrant's request as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorney's fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding, to the fullest extent permitted by applicable law.

Section 102(b)(7) of the Delaware General Corporation Law permits a corporation to provide in its certificate of incorporation that a director 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, except (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) for payments of unlawful dividends or unlawful stock repurchases or redemptions; or (iv) for any transaction from which the director derived an improper personal benefit. The Registrant's certificate of incorporation provides that the Registrant's directors shall not be personally liable to it or its stockholders for monetary damages for breach of fiduciary duty as a director and that if the Delaware General Corporation Law is amended to authorize corporate action further eliminating or limiting the personal liability of directors, then the liability of the Registrant's directors shall be eliminated or limited to the fullest extent permitted by the Delaware General Corporation Law, as so amended.

As permitted by the Delaware General Corporation Law, we have entered into separate indemnification agreements with each of our directors and certain of our officers which require the Registrant, among other things, to indemnify them against certain liabilities which may arise by reason of their status as directors or officers.

We have an insurance policy in place that covers under which its directors and officers are insured, within the limits and subject to the limitations of those policies, against certain expenses in connection with the defense of, and certain liabilities which might be imposed as a result of, actions, suits or proceedings to which they are parties by reason of being or having

II-1

Table of Contents

been directors or officers. The coverage provided by these policies may apply whether or not the Registrant would have the power to indemnify such person against such liability under the provisions of the Delaware General Corporation Law.

These indemnification provisions and the indemnification agreements entered into between the Registrant and the Registrant's officers and directors may be sufficiently broad to permit indemnification of the Registrant's officers and directors for liabilities (including reimbursement of expenses incurred) arising under the Securities Act.

In any underwriting agreement, securities purchase agreement, placement agency agreement or similar agreement that we may enter into in connection with the sale of certain securities being registered hereby, the underwriter, purchaser, or placement agent will agree to indemnify, under certain conditions, us, our directors, our officers and persons who control us, within the meaning of the Securities Act, against certain liabilities.

Item 15. Recent Sales of Unregistered Securities

The Company has not issued unregistered securities to any person within the last three years other than:

On March 14, 2024, the Registrant entered into Subscription Agreements (the "Subscription Agreements") with the officers and directors of the Registrant to purchase an aggregate of 294,644 shares of the registrant's Common Stock, respectively, (the "Private Placement Shares") at a price of $0.98 per Private Placement Share. The Private Placement Shares were sold without registration under the Act, in reliance upon the exemptions from registration provided under Section 4(a)(2) of the Act in reliance upon the exemptions from registration provided under Section 4(a)(2) of the Act and Regulation D promulgated under the Act ("Regulation D"). Each purchaser represented in the Subscription Agreements, among other things, that such purchaser was acquiring the Private Placement Shares for investment for the purchaser's account and that the purchaser was an "accredited investor" within the meaning of Regulation D.

On December 12, 2024, the registrant issued warrants to purchase an aggregate of 1,456,667 shares of its Common Stock to lenders in connection with entering into a loan agreement. The warrants have an exercise price of $0.6315 per share, are immediately exercisable, and expire on December 12, 2034. The warrants were issued and sold without registration under the Act, in reliance upon the exemptions from registration provided under Section 4(a)(2) of the Act and Regulation D. The lenders represented, among other things, that such lender was acquiring the warrants for investment for the lender's account and that such lender was an "accredited investor" within the meaning of Regulation D.

On August 1, 2025, Xcel entered into a placement agency agreement with Maxim Group LLC, as lead placement agent, relating to a best efforts public offering (the "Offering") of 2,181,818 shares of the Xcel's Common Stock, par value $0.001 per share, at a price to the public of $1.10 per Share. Robert W. D'Loren, Chairman and Chief Executive Officer of Xcel, purchased 124,200 Shares in the Offering, and Mark DiSanto, a Director of Xcel, purchased 91,800 Shares in the Offering. The closing of the Offering occurred on August 4, 2025. On August 1, 2025, Xcel entered into a securities purchase agreement in favor of each purchaser to purchase the 2,181,818 shares sold in the Offering. This securities purchase agreement contains customary representations, warranties and covenants made by Xcel. On August 1, 2025, Xcel entered into Subscription Agreements (the "Subscription Agreements") with Robert D'Loren and Mark DiSanto to purchase 82,159 and 60,883 shares, respectively, (the "Private Placement Shares") at a price of $1.38 per Private Placement Share. The purchase of the Private Placement Shares closed concurrently with the Offering. Upon closing of the sale of the Private Placement Shares, Xcel issued to Maxim Group LLC, as compensation, warrants to purchase up to 3,567 shares of Common Stock, which warrants were identical to the placement agent's warrants.

On December 17, 2025, we entered into the Purchase Agreement with several institutional and accredited investors for the issuance and sale in a private placement of securities for gross proceeds of $2.05 million. The Purchase Agreement provides for the issuance and sale of: (i) 896,126 shares of the Company's Common Stock, (ii) Pre-Funded Warrants to purchase from the Company a total of 773,929 shares of Common Stock, at an exercise price per share equal to $0.001, and (iii) Warrants to purchase from the Company a total of 835,023 shares of Common Stock, at an exercise price per share equal to $3.00. Also on this date, we issued Placement Agent Warrants to purchase 4% of the aggregate number of Shares and Pre-Funded Warrants sold in the Private Placement, for an aggregate of up to 66,802 shares of Common Stock, at an exercise price per share equal to $1.165 per share to the Placement Agent. The shares of Common Stock, Pre-Funded Warrants and Warrants were sold without registration under the Act, in reliance upon the exemptions from registration

provided under Section 4(a)(2) of the Act in reliance upon the exemptions from registration provided under Section 4(a)(2) of the Act and Regulation D promulgated under the Act ("Regulation D"). Each purchaser represented in the Subscription Agreements, among other things, that such purchaser was acquiring the Private Placement Shares for investment for the purchaser's account and that the purchaser was an "accredited investor" within the meaning of Regulation D.

Item 16. Exhibits.

The exhibits to this registration statement are listed in the Exhibit Index to this registration statement, which immediately precedes the signature page and which Exhibit Index is hereby incorporated by reference.

Item 17. Undertakings.

The undersigned Registrant hereby undertakes:

(1)

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

(i)

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

(ii)

to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Filing Fee Tables" in the effective registration statement; and

(iii)

to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement; provided, however, that paragraphs (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 SEC by the Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

(2)

That, for the purpose of determining any liability under the Securities Act of 1933, 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 of 1933 to any purchaser, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness. 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 first use, 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 date of first use.

(5)

That, for purposes of determining any liability under the Securities Act of 1933, each filing of Registrant's annual report pursuant to Section 13(a) or section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act

II-3

Table of Contents

of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(6)

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.
