ABOUT THIS PROSPECTUS SUPPLEMENT

This document is in two parts. The first part is this prospectus supplement, which describes the terms of the offering and also adds to and updates information contained in the accompanying prospectus and the documents incorporated by reference into this prospectus supplement and the accompanying prospectus. The second part consists of a prospectus dated December 17, 2024, included in the registration statement on Form S-3 (File No. 333-276298) that we filed with the U.S. Securities and Exchange Commission (the “SEC”) under the Securities Act, utilizing a “shelf” registration process.

Overview

Following the acquisition of Streamex on May 28, 2025 (the “Share Exchange”), BioSig now operates two principal business segments: (i) healthcare innovation through our PURE EP™ platform and ViralClear BioSciences, and (ii) tokenized finance and real-world asset (“RWA”) digitization through Streamex.

Medical Devices

Our advanced digital signal processing technology platform, the PURE EP™ Platform (“PURE EP”), delivers insights to electrophysiologists for ablation treatments of cardiovascular arrhythmias. The PURE EP™ Platform enables electrophysiologists to acquire raw signal data in real-time-absent of unnecessary noise or interference-to maximize procedural success and minimize unnecessary inefficiencies. As physician advocates, we believe that the ability to maintain the integrity of intracardiac signals with precision and clarity without driving up procedural costs has never been more pertinent.

By capturing critical cardiac signals-even the most complex-PURE EP is designed to enhance clinical decision-making and improve clinical workflow for all types of arrhythmias, even the most challenging procedures for cardiac arrhythmias, like ventricular tachycardia (VT) and atrial fibrillation (AF).

BioSig has pivoted from a focus on commercial distribution of hardware to the research and development of novel software algorithms that advance our understanding of mechanisms and tissue characteristics. Data collection began in December 2023 and is ongoing. Despite its rapid adoption, there is room to improve the long-term outcomes of pulsed field ablation (PFA). Our primary focus is aimed at improving the specificity of PFA treatment and improving clinical outcomes.

Our owned patent portfolio now includes 42 issued/allowed utility patents (30 utility patents where BioSig is at least one of the applicants). 31 additional U.S. and foreign utility patent applications are pending covering various aspects of our PURE EP System for recording, measuring, calculating and displaying of electrocardiograms during cardiac ablation procedures (31 U.S. and foreign utility patent applications where either BioSig, Mayo Foundation for Medical Education and Research (“Mayo”), or both is at least one of the applicants). We also have one U.S. patent and one U.S. Pending application directed to artificial intelligence (AI). We also have 30 issued worldwide design patents, which cover various features of our display screens and graphical user interface for enhanced visualization of biomedical signals (30 design patents where BioSig is at least one of the applicants). Finally, we have licenses to 12 (issued/allowed) patents and 9 additional worldwide utility patent applications from Mayo that are pending (12 issued/allowed patents and 9 applications where only Mayo is the applicant). These patents and applications are generally directed to electroporation and stimulation.

Tokenized Finance and RWA Digitization

Streamex is developing a blockchain-based technology platform intended to support the tokenization of real-world assets, including future production contracts, royalties, and other physical asset interests. The Company aims to operate as an infrastructure provider, enabling the future issuance, trading, and custody of digital tokens backed by tangible commodities, beginning with gold. The platform remains under development and has not yet launched or facilitated any asset tokenization or exchange activity.

Nature of Operations

Streamex is a software development company focused on building advanced digital infrastructure for the tokenization and exchange of commodity-linked financial products. The Company combines proprietary intangible assets, a skilled workforce, and a structured operational framework created to produce outputs in the form of:

	●	RWAs

	●	Decentralized exchange infrastructure.

	●	Private placement and capital markets access platforms.

	●	Gold denominated structured products.

These outputs are expected to enable monetization through multiple fee-based and recurring revenue models across the commodity and digital asset lifecycle.

Streamex Revenue Streams

Streamex’s revenue model consists of the following core business lines:

Tokenization of RWAs: Streamex seeks to enable the digital transformation of tangible and intangible assets—such as future gold deliveries, royalties, and real estate—into blockchain-based tokens. Revenue is generated through:

	○	Issuance fees on new token creation;

	○	Secondary trading and exchange-related transaction fees; and

	○	Platform access and usage fees.

Exchange Infrastructure: Streamex will operate a compliant digital exchange for trading tokenized assets. The platform supports listing, custody, and liquidity mechanisms for RWAs. Revenue streams include:

	○	Transaction and trading fees;

	○	Listing fees for new tokens; and

	○	Liquidity provisioning incentives and spreads.

Private Placement and Capital Markets Access: Streamex intends to offer access to tokenized instruments representing private placements and structured deals for institutional and qualified investors. Revenue sources include:

	○	Underwriting and origination fees;

	○	Placement agent fees; and

	○	Subscription-based services and investor access products.

For the three months ended March 31, 2025, Streamex generated approximately $200,000 in revenue from early-stage consulting and platform access agreements, specifically as part of pilot implementations of its tokenized gold financing infrastructure and related services. The Company anticipates continued revenue growth following the Share Exchange, supported by increased issuance activity, platform usage, and capital deployment.

Strategy

Streamex’s initial product offering is intended to be a tokenized gold financing program, whereby it will enter into pre-buy contracts with mining operators for the future delivery of gold. In these arrangements:

	●	The gold producer receives upfront funding from Streamex.

	●	Streamex obtains the contractual right to receive a defined volume of gold at maturity.

	●	The delivery rights are tokenized and issued to investors as blockchain-based volumetric claims.

	●	The tokens are tradable and settleable globally, with holders bearing the full economic risk and return associated with changes in gold prices and mine performance.

S-5

Streamex expects to earn revenue through origination fees, token sale spreads, and treasury capital redeployment, while operating with minimal direct exposure to commodity price risk.

Growth

Streamex plans to scale its operations through:

	●	Increasing the number and volume of tokenized gold contracts.

	●	Launching a secondary marketplace to improve token liquidity.

	●	Expanding the platform to support additional asset classes such as industrial metals, energy royalties, and other RWAs.

	●	Partnering with institutional market participants for underwriting, syndication, and capital markets integration.

The Company also intends to scale its internal treasury strategy, re-deploying capital across multiple token issuance cycles per year to increase gold-linked asset holdings and maximize capital efficiency.

Implications of Being a Smaller Reporting Company

We are a “smaller reporting company,” meaning that the market value of our stock held by non-affiliates is less than $700 million and our annual revenue was less than $100 million during the most recently completed fiscal year. We may continue to be a smaller reporting company if either (i) the market value of our stock held by non-affiliates is less than $250 million or (ii) our annual revenue was less than $100 million during the most recently completed fiscal year and the market value of our stock held by non-affiliates was less than $700 million. For so long as we remain a smaller reporting company, we are permitted and intend to rely on exemptions from certain disclosure. As a result, the information that we provide to our stockholders may be different than you might receive from other public reporting companies in which you hold equity interests.

Preliminary Results for the Six Months Ended June 30, 2025

Unaudited preliminary approximated results for the six months ended June 30, 2025 are as follows:

	June 30, 2025
Operating Expenses	$	(23,300	)

RISK FACTORS

An investment in our securities involves a high degree of risk. Prior to making a decision about investing in our securities, you should carefully consider the following risks and uncertainties, as well as those discussed under the caption “Risk Factors” in the accompanying prospectus and in the documents incorporated by reference herein and therein. If any of the risks described in this prospectus supplement, the accompanying prospectus or the documents incorporated by reference herein and therein, actually occur, our business, prospects, financial condition or operating results could be harmed. In that case, the trading price of our securities could decline, and you may lose all or part of your investment. Additional risks and uncertainties not presently known to us or that we currently believe are immaterial may also impair our business operations and our liquidity. You should also refer to the other information contained in this prospectus supplement and the accompanying prospectus, or incorporated by reference herein and therein, including our financial statements and the related notes thereto and the information set forth under the heading “Cautionary Note Regarding Forward-Looking Statements.”

Risks Related to Our Business and Industry

If our stockholders do not approve the proposals to be presented at the upcoming special meeting, including proposals relating to our acquisition of Streamex and financing arrangements with YA II PN, Ltd. (“Yorkville”), our ability to execute our business strategy could be materially and adversely affected.

On May 23, 2025, the Company entered into that certain Share Purchase Agreement (the “Share Purchase Agreement”) with Streamex, ExchangeCo, CallCo, the Streamex Shareholders, and the Trustee for the benefit of the holders of exchangeable shares (the “Exchangeable Shares”) issued in connection with the Share Purchase Agreement. Pursuant to the Share Purchase Agreement, the Company acquired all of the issued and outstanding shares of Streamex in exchange for 109,070,079 Exchangeable Shares at a fixed exchange ratio of 2.0469 Exchangeable Shares per share of Streamex (the “Exchange Ratio”), subject to certain adjustments. Each Exchangeable Share is exchangeable on a one-for-one basis into one share of our common stock, but, under applicable rules of the Nasdaq Stock Market LLC (“Nasdaq”), we may not issue more than 19.9% of our pre-transaction outstanding common stock without obtaining stockholder approval.

To obtain approval for the issuance of the full number of our shares of common stock in excess of this limit and to implement other key aspects of the post-transaction structure, we have called a special meeting of stockholders (the “Special Meeting”) to approve the following proposals (collectively, the “Parent Stockholder Matters”):

	●	Proposal 1 – Approval of the issuance of our shares of common stock exchangeable for Exchangeable Shares and one share of Special Voting Preferred Stock in connection with the Share Purchase Agreement;
	●	Proposal 2 – Approval of the issuance of our shares of common stock underlying convertible debentures to be issued to Yorkville (the “Convertible Debentures”) in a financing of up to $50 million (the “Convertible Debt Financing”) and related matters;
	●	Proposal 3 – Approval of the Third Amendment to our 2023 Long-Term Incentive Plan to increase the number of shares authorized for issuance;
	●	Proposal 4 – Approval of the issuance of 19.99% or more of our common stock pursuant to the Standby Equity Purchase Agreement, dated July 7, 2025, with Yorkville (the “SEPA”);
	●	Proposal 5 – Approval of an amendment to our Amended and Restated Certificate of Incorporation to increase the number of authorized shares of common stock from 200,000,000 to 500,000,000; and
	●	Proposal 6 – Approval of an amendment to our Amended and Restated Certificate of Incorporation to classify our board of directors into three staggered classes.

If these proposals are not approved by our stockholders, the consequences could be significant. In particular, if the required stockholder approval is not obtained within six months of the closing of the Share Purchase Agreement, the Exchange Ratio will be adjusted from 1.0 to 1.25, resulting in the potential issuance of additional shares of common stock and further dilution to our existing stockholders. Moreover, without approval of the authorized share increase and other share issuance proposals, we may be unable to issue the shares necessary to satisfy obligations under the Share Purchase Agreement, the SEPA, or the Convertible Debentures, which could limit our capital-raising ability, or force renegotiation on unfavorable terms.

S-9

Failure to approve the Parent Stockholder Matters could also create corporate governance uncertainty, delay integration of the combined business, and affect our eligibility to maintain or relist our securities on Nasdaq.

Additionally, the issuance of a significant number of shares in the future in connection with these transactions may result in substantial dilution to our existing stockholders, and our complex capital structure could negatively impact investor confidence and market valuation. Further, there is no assurance that Nasdaq will approve any initial listing application filed in connection with the acquisition of Streamex, and failure to secure such approval may impair our market access and liquidity.

Streamex has a limited operating history and has incurred significant losses since inception.

Streamex was incorporated on April 5, 2024, and has a limited operating history upon which investors may evaluate its business, prospects, and performance. As a newly formed company, Streamex is subject to all of the risks and uncertainties typically associated with the development of a new business, including the need to attract customers, develop and commercialize its software products and services, and achieve market acceptance. Streamex has incurred significant operating losses since inception. For the period from incorporation to December 31, 2024, Streamex incurred a net loss of approximately CAD$1.7 million, and as of March 31, 2025, it had an accumulated deficit of approximately CAD$1.9 million.

The audited financial statements of Streamex for the period ended December 31, 2024, include a going concern qualification from its independent registered public accounting firm, which raises substantial doubt about Streamex’s ability to continue as a going concern. Streamex’s ability to continue as a going concern depends on its ability to obtain additional financing, generate sufficient revenue, and achieve profitability. There can be no assurance that Biosig will satisfy the conditions required to obtain the funds under its agreements with Yorkville, or that Streamex will be successful in securing additional financing on favorable terms, or at all, or that it will achieve positive cash flow or profitability in the future. If Streamex is unable to address these risks, its business, financial condition, and results of operations could be materially and adversely affected.

Risks Related to our Convertible Debentures and Potential Future Indebtedness

Our level and terms of indebtedness could adversely affect our ability to raise additional capital to further execute on our gold-linked tokenization and treasury strategy, fund other operations, and take advantage of new business opportunities.

Our indebtedness, whether currently existing or incurred in the future, could have important consequences to us, including:

	●	limiting our ability to use a substantial portion of our cash flow from operations in other areas of our business, including for the development and implementation of our gold treasury strategy, working capital, developing our products and services, capital expenditures, and other general business activities and investment opportunities in our company, because we must dedicate a substantial portion of these funds to pay interest on and/or service our debt;

	●	limiting our ability to obtain additional financing in the future for the development and implementation of our gold treasury strategy, working capital, capital expenditures, debt service, acquisitions, execution of our strategy, and other expenses or investments planned by us;

	●	limiting our flexibility and our ability to capitalize on business opportunities and to react to competitive pressures and adverse changes in government regulation, our business, and our industry;

	●	increasing our vulnerability to a downturn in our business and to adverse economic and industry conditions generally;

	●	requiring us to maintain liquid assets to cover any repurchase, conversion or collateral requirement of the Convertible Debentures;

	●	placing us at a competitive disadvantage as compared to our competitors that are less leveraged; and

	●	limiting our ability, or increasing the costs, to refinance indebtedness.

S-10

We may be unable to service our indebtedness, which could cause us to default on our debt obligations and could force us into bankruptcy or liquidation.

Our ability to make scheduled payments on and to refinance our indebtedness (whether currently existing or incurred in the future) depends, and will depend, on and is subject to our financial and operating performance, which is influenced, in part, by general economic, financial, competitive, legislative, regulatory, counterparty business, and other risks that are beyond our control, including the availability of financing in the U.S. banking and capital markets. If our cash flows and capital resources are insufficient to fund our debt service obligations, we may be forced to reduce or delay capital expenditures, sell assets, seek additional capital, or restructure or refinance our indebtedness. We cannot assure you that future borrowings will be available to us in an amount sufficient to enable us to service our indebtedness, to refinance our indebtedness, or to fund our other liquidity needs. Even if refinancing indebtedness is available, any refinancing of our indebtedness could be at higher interest rates and may require us to comply with more onerous covenants that could further restrict our business operations. In addition, our gold-linked tokenization and treasury strategy anticipates that we may issue additional debt in future periods to finance additional purchases of pre-buy gold delivery contracts, but if we are unable to generate sufficient cash flow to service our debt and make necessary capital expenditures, we may be required to sell gold-linked tokens or liquidate related assets. These alternative measures may not be successful and may not permit us to meet our scheduled debt service obligations or our financial covenants, which could cause us to default on our debt obligations. In addition, any failure to make payments of interest and principal on our outstanding indebtedness on a timely basis would likely result in a reduction of our credit rating, which could harm our ability to incur additional indebtedness.

Upon the occurrence of an event of default under our indebtedness (whether currently existing or incurred in the future), the holders of the defaulted indebtedness could elect to declare all the funds borrowed to be due and payable, together with accrued and unpaid interest. Any of these events could in turn result in cross-defaults under any other indebtedness. We may not have sufficient funds available to pay the amounts due upon any such default, particularly in the event that there has been a decrease in the market value of our gold-linked tokens or related gold assets, and we may not be able to raise additional funds to pay such amounts on a timely basis, on terms we find acceptable, or at all. Any financing that we may undertake under such circumstances could result in substantial dilution of our existing stockholders, and in the absence of being able to obtain such financing, we could be forced into bankruptcy or liquidation.

We may not have the ability to raise the funds necessary to settle conversions of the Convertible Debentures in cash or to repurchase the Convertible Debentures for cash upon events which require repayment of the Convertible Debentures, including the mandatory repurchase provisions y, and any future debt may contain, limitations on our ability to engage in cash-settled conversions or repurchases of the Convertible Debentures.

In connection with any conversion of the Convertible Debentures, we may elect (and if our common stock is not freely tradable, we will be required) to make cash payments in respect of the Convertible Debentures being converted. However, any future debt may contain limitations on our ability to (i) pay cash upon conversion or redemption of the Convertible Debentures, which may require us to elect to deliver solely shares of our common stock to settle such conversion (other than paying cash in lieu of delivering any fractional share), or (ii) sell certain gold assets or other assets to generate cash that can be used to make such cash payments.

Standard events of default are included in the Convertible Debentures, pursuant to which the holder may declare the Convertible Debentures immediately due and payable and exercise other remedies, including the right to foreclose on the collateral securing the obligations.

Absent a waiver from the applicable holders of the Convertible Debentures, our failure to offer to purchase all applicable Convertible Debentures or to purchase all validly tendered Convertible Debentures or repay the Convertible Debentures upon would be an event of default. Additionally, the collateral held by the collateral agent may not be available to us to repurchase or repay the Convertible Debentures.

S-11

Moreover, the exercise by holders of the Convertible Debentures of their right to require us to repurchase such Convertible Debentures could cause a default under future debt agreements, even if the change of control or fundamental change itself does not, due to the financial effect of such repurchase on us.

Despite our current level of indebtedness, we may incur substantially more indebtedness and enter into other transactions in the future which could further exacerbate the risks related to our indebtedness.

Our gold tokenization strategy includes financing the acquisition of pre-purchased gold delivery contracts and related gold-linked digital instruments using proceeds from equity and debt financings and, potentially, cash flows from operations. As such, despite our current level of indebtedness, we may incur substantially more indebtedness, and we may enter into other transactions in the future. Even if we were to enter into debt or other arrangements that contain restrictions on our ability to incur additional indebtedness, these restrictions may be subject to a number of qualifications and exceptions that would allow us to incur significant additional indebtedness. To the extent we incur additional indebtedness or other obligations, the risks described herein with respect to our indebtedness may increase significantly.

Future resales of our common stock as a result of registration rights granted to Yorkville in connection with the Convertible Debentures may cause the market price of our securities to drop significantly, even if our business is doing well.

In connection with our issuance of the Convertible Debentures of up to $50 million to Yorkville, we have agreed to file and cause to be declared effective a resale registration statement (the “Resale Registration Statement”) to register for resale all of the shares of our common stock issuable upon conversion of the Convertible Debentures (the “Conversion Shares”), including shares that may be issued pursuant to the anti-dilution provisions of the Convertible Debentures and any shares issuable as a result of stock splits, stock dividends, recapitalizations or similar events. The availability of such a large number of shares for resale under the Resale Registration Statement, particularly shortly after the registration statement becomes effective, could create significant downward pressure on the market price of our common stock.

In addition, following the effectiveness of the Resale Registration Statement, Yorkville may convert all or a portion of the Convertible Debentures and resell the Conversion Shares in the public market at its discretion, subject only to contractual and regulatory limitations. This could result in substantial dilution to our existing stockholders, especially given the conversion price formula based on market prices, and may further increase the volatility of our stock price. Sales of substantial amounts of our common stock by Yorkville or the perception that such sales could occur may also impair our ability to raise capital through the future sale of equity securities at a time and at a price that we deem appropriate or necessary.

Moreover, because the registration of the Conversion Shares is a condition to the closing of a Convertible Debenture in the principal amount of $25 million, we are contractually obligated to complete the registration process. If we fail to do so within the required timeframe, we may be subject to penalties or be unable to access the remaining capital under the Debenture Purchase Agreement we entered into with Yorkville on July 7, 2025, which could adversely affect our liquidity and financial condition.

Risks Related to This Offering

You may experience immediate and substantial dilution as a result of this offering.

The public offering price of our common stock is substantially higher than the pro forma as adjusted net tangible book value per share of our common stock. Therefore, if you purchase shares of our common stock in this offering, you will pay a price per share that substantially exceeds our pro forma as adjusted net tangible book value per share after this offering. Our net tangible book value as of March 31, 2025, was approximately $2.37 million, or $0.10 per share of common stock. Our pro forma net tangible book value as of March 31, 2025, giving effect to (i) the assumed reclassification of the Exchangeable Shares and finder fee liabilities to equity, which includes the issuance of 109,070,079 and 1,064,000 shares of common stock underlying the Exchangeable Shares and finder fee liabilities, respectively, and (ii) the assumed issuance of the Convertible Debentures in the aggregate principal amount of $50 million, whose issuance remains subject to shareholder approval, was approximately $2.51 million or $0.02 per share of common stock. Based on the public offering price of $3.90 per share, you will experience immediate dilution of $3.78 per share, representing the difference between our pro forma as adjusted net tangible book value per share after giving effect to this offering and the public offering price per share. See the section entitled “Dilution” on page S-16 below for a more detailed illustration of the dilution you may incur if you participate in this offering.

Management will have broad discretion as to the use of the net proceeds from this offering, and we may not use the proceeds effectively.

We intend to use the net proceeds of this offering, if any, to purchase gold bullion in accordance with our investment policy, for working capital and for general corporate purposes. Our management will have broad discretion in the application of the net proceeds from this offering, if any, and could spend the proceeds in ways that do not improve our results of operations or enhance the value of our common stock. You will be relying on the judgment of our management concerning these uses and you will not have the opportunity, as part of your investment decision, to assess whether the proceeds are being used appropriately. The failure of our management to apply these funds effectively could result in unfavorable returns and uncertainty about our prospects, each of which could cause the price of our common stock to decline.

Risks Related to our Common Stock

Our failure to meet the continued listing requirements of Nasdaq could result in a delisting of our common stock, which could negatively impact the market price and liquidity of our common stock and our ability to access the capital markets.

Our common stock is listed on the Nasdaq Capital Market. If we fail to satisfy the continued listing requirements of Nasdaq, such as the minimum bid price, shareholders’ equity, public float and other requirements, Nasdaq may take steps to delist our common stock. Such a delisting would have a negative effect on the price of our common stock, impair the ability to sell or purchase our common stock when persons wish to do so, and any delisting materially adversely affect our ability to raise capital or pursue strategic restructuring, refinancing or other transactions on acceptable terms, or at all. Delisting from the Nasdaq Capital Market could also have other negative results, including the potential loss of institutional investor interest and fewer business development opportunities. In the event of a delisting, we would attempt to take actions to restore our compliance with Nasdaq’s listing requirements, but we can provide no assurance that any such action taken by us would allow our common stock to become listed again, stabilize the market price or improve the liquidity of our common stock, prevent our common stock from dropping below the Nasdaq minimum bid price requirement or prevent future non-compliance with Nasdaq’s listing requirements.

On March 5, 2024, the Company received a letter from the Staff stating that the Company had not regained compliance with Listing Rule 5550(a)(2) because the Company’s common stock did not meet the minimum bid price of $1.00 per share required for continued listing on the Nasdaq Capital Market, and the Company is not eligible for a second 180 day cure period under Rule 5810(c)(3)(A)(2) because the Company does not comply with the $5,000,000 minimum stockholders’ equity initial listing requirement for Nasdaq, and that accordingly, Nasdaq would delist the Company’s common stock unless the Company requested an appeal of this determination. On March 11, 2024, the Company submitted a request for a hearing before Hearings Panel to appeal the delisting determination.

On March 12, 2024, the Company received a letter from the Staff stating that based upon the Staff’s review of the Company and pursuant to Listing Rule 5101, the Staff believes that the Company no longer has an operating business and is a “public shell,” and that the continued listing of its securities is no longer warranted, in view of work force reductions and resignations of members of the board of directors and officers. The letter further stated that the Company no longer meets the requirement of Rule 5550(b)(2) to maintain a minimum market value of listed securities of $35 million, if none of the other standards set forth in Rule 5550(b) is met. The Staff stated that the foregoing matters serve as an additional basis for delisting the Company’s common stock from the Nasdaq Stock Market, and that the Panel will consider this matter in rendering a determination regarding the Company’s continued listing on the Nasdaq Capital Market. The Company appealed the foregoing determinations. The requested hearing before the Panel was held on May 7, 2024.

On June 10, 2024, the Company received formal notice that the Panel had determined to delist the Company’s common stock from Nasdaq due to the Company’s continued non-compliance with the minimum stockholders’ equity requirement set forth in Nasdaq Listing Rule 5550(b)(2) for continued listing on Nasdaq. As a result, trading in the Company’s common stock was suspended on Nasdaq effective with the open of business on Wednesday, June 12, 2024. The Company’s common was eligible to trade on the OTC Markets’ Pink Current Information tier under symbol “BSGM” effective with the open of trading on Wednesday, June 12, 2024. The Company sought the Panel’s reconsideration in accordance with the Nasdaq Listing Rules

On June 24, 2024, the Company was notified by Nasdaq that the Panel had declined to reconsider its decision dated June 10, 2024 to delist the Company’s common stock from Nasdaq (the “Delisting Decision”). Trading in the Company’s securities remained suspended on Nasdaq effective with the open of business on June 12, 2024, at which point the Company’s common stock was eligible to trade on the OTC Market’s Pink Current Information tier.

On July 10, 2024, the Company filed a submission in support of an appeal to the Listing Council.

S-14

On July 23, 2024, the Company commenced trading of its common stock on the OTCQB, operated by OTC Markets Group, Inc.

On October 18, 2024, the Company was notified by the Staff that the Listing Council had granted the Company an exception through March 7, 2025, to evidence compliance with Nasdaq Listing Rule 5550(b), namely either the $35 million in market value of listed securities requirement or the alternative requirement of $2.5 million in stockholders’ equity (the “Equity Rule”) for continued listing on The Nasdaq Capital Market.

On October 23, 2024, the Company’s common stock resumed trading on the Nasdaq Capital Market.

On October 24, 2024, the Company received a letter from the Staff notifying the Company that based upon the closing bid price of the Company’s common stock from the period of June 11, 2024 through the reinstatement date, October 23, 2024, the Company did not meet the minimum bid price of $1.00 per share required by the Listing Rules and as a result, the Company no longer met this requirement. However, the Listing Rules also provided the Company a compliance period of 180 calendar days in which to regain compliance. Since then, Staff had determined that for the 10 consecutive business days, from October 30, 2024, to November 12, 2024, the closing bid price of the Company’s common stock was at $1.00 per share or greater. Accordingly, the Company regained compliance with Listing Rule 5550(a)(2) and this matter closed as of November 13, 2024.

On March 6, 2025, the Company submitted supporting documents to the Listing Council evidencing compliance with the Equity Rule. And on March 24, 2025, the Company was notified by the Office of General Counsel of Nasdaq that the Company had successfully met the qualifications to regain full compliance for continued listing on the Nasdaq Capital Market.

On April 11, 2025, the Company received a letter from the Staff indicating that, based upon the closing bid price of the Company’s common stock for the 30 consecutive business day period between February 27, 2025, through April 10, 2025, the Company did not meet the minimum bid price of $1.00 per share required for continued listing on Nasdaq pursuant to Nasdaq Listing Rule 5550(a)(2). The letter also indicated that the Company will be provided with a compliance period of 180 calendar days, or until October 8, 2025 (the “Compliance Period”), in which to regain compliance pursuant to Nasdaq Listing Rule 5810(c)(3)(A). Since then, Staff has determined that that the Company has regained compliance with Listing Rule 5550(a)(2) and this matter is closed as of May 14, 2025.

If we fail to satisfy the continued listing requirements of Nasdaq, Nasdaq may again take steps to delist our securities. Such a delisting would likely have a negative effect on the price and liquidity of our common stock and would impair your ability to sell our common stock purchased in this offering when you wish to do so. In the event of a delisting, we would again take actions to restore our compliance with Nasdaq’s listing requirements, but we can provide no assurance that any such action taken by us would allow our common stock to become listed again, stabilize the market price or improve the liquidity of our securities, prevent our common stock from dropping below the Nasdaq minimum share price requirement or prevent future non-compliance with Nasdaq’s listing requirements.

If our common stock is delisted and we are not able to list our common stock on another national securities exchange, we expect our securities would be quoted on an over-the-counter market. There can be no assurance that an active trading market for our common stock will develop or be sustained.

S-15

DILUTION

If you invest in our common stock, your interest will be diluted immediately to the extent of the difference between the offering price per share you will pay in this offering and the pro forma as adjusted net tangible book value per share of our common stock immediately after giving effect to (i) the assumed reclassification of the Exchangeable Shares and finder fee liabilities to equity, which includes the issuance of 109,070,079 and 1,064,000 shares of common stock underlying the Exchangeable Shares and finder fee liabilities, respectively, (ii) the assumed issuance of the Convertible Debentures in the aggregate principal amount of $50 million, whose issuance remains subject to shareholder approval, and (iii) this offering.

We calculate net tangible book value per share by dividing the net tangible book value, which is the total tangible assets less total liabilities, by the number of outstanding shares of our common stock. Dilution represents the difference between the amount per share paid by purchasers of shares in this offering and the pro forma as adjusted net tangible book value per share of our common stock immediately after giving effect to (i) the consummation of the Share Exchange; (ii) the assumed reclassification of the Exchangeable Shares and finder fee liabilities to equity, which includes the issuance of 109,070,079 and 1,064,000 shares of common stock underlying the Exchangeable Shares and finder fee liabilities, respectively, (iii) the assumed issuance of the Convertible Debentures, the issuance of which remains subject to shareholder approval; and (iv) this offering. Our net tangible book value as of March 31, 2025 was approximately $2,370,000 or $0.10 per share of common stock. Our pro forma net tangible book value as of March 31, 2025, giving effect to (i) the assumed reclassification of the Exchangeable Shares and finder fee liabilities to equity, which includes the issuance of 109,070,079 and 1,064,000 shares of common stock underlying the Exchangeable Shares and finder fee liabilities, respectively and (ii) the assumed issuance of the Convertible Debentures, was approximately $2.51 million or $0.02 per share of common stock.

After giving further effect to our sale of 3,852,149 shares of common stock in this offering at the public offering price of $3.90 per share, and after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us, our pro forma as adjusted net tangible book value as of March 31, 2025 would have been $16.13 million, or $0.12 per share. This represents an immediate increase in pro forma as adjusted net tangible book value of $0.10 per share to our existing stockholders and an immediate dilution in pro forma as adjusted net tangible book value of $3.78 per share to new investors purchasing common stock in this offering. Dilution per share to new investors purchasing common stock in this offering is determined by subtracting pro forma as adjusted net tangible book value per share after this offering from the public offering price per share paid by new investors.

The following table illustrates this dilution on a per share basis:

Public offering price per share			$	3.90
Pro-forma net tangible book value per share as of March 31, 2025	$	0.02
Increase in pro forma net tangible book value per share attributable to this offering	$	0.10
Pro forma as adjusted net tangible book value per share as of March 31, 2025, after giving effect to this offering			$	0.12
Dilution per share to new investors in this offering			$	3.78

The above discussion and table are based on 24,248,315 shares of our common stock outstanding as of March 31, 2025, and exclude as of that date:

●

5,577,260 shares of common stock issuable upon exercise of warrants outstanding, with a weighted average exercise price of $4.31 per share;

●

2,486,000 shares of common stock issuable upon exercise of options outstanding at a weighted average exercise price of $0.77 per share;

●

1,160,830 shares of common stock subject to restricted stock units;

●

4,251,595 shares of common stock reserved and available for future issuance under our 2023 Plan; and

●

564,234 shares of common stock issuable upon conversion of outstanding Series C Preferred Stock at the conversion price of $0.3197 per share and the stated value per share of $1,000 (which includes the payment of dividends accrued on the Series C Preferred Stock in an aggregate of 235,801 shares of common stock as of March 31, 2025 at a conversion rate of $0.4831).

Except as otherwise indicated, all information in this prospectus supplement assumes no exercise, conversion, or settlement of the outstanding options, preferred stock, restricted stock units or warrants described above.

To the extent that any of these outstanding options, warrants, preferred stock, or restricted stock units are exercised, converted or settled at prices per share below the public offering price per share in this offering or we issue additional shares under our equity incentive plans at prices below the public offering price per share in this offering, you may experience further dilution. In addition, we may choose to raise additional capital due to market conditions or strategic considerations even if we believe we have sufficient funds for our current or future operating plans. To the extent that we raise additional capital by issuing equity or convertible debt securities, your ownership will be further diluted.

S-16

DIVIDEND POLICY

We have never paid cash dividends on our common stock and do not anticipate paying any cash dividends in the foreseeable future but intend to retain our capital resources for reinvestment in our business. 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. Our ability to pay dividends is presently restricted pursuant to the terms of our Series C Preferred Stock.

DESCRIPTION OF THE COMMON STOCK

The material terms and provisions of our common stock are described under the caption “Description of Capital Stock” in the accompanying prospectus and are incorporated herein by reference.

USE OF PROCEEDS

We expect to receive net proceeds from this offering of approximately $13.6 million, after deducting the estimated underwriting discounts and commissions and the estimated offering expenses payable by us.

We intend to use the net proceeds from this offering to purchase gold bullion in accordance with our investment policy, for working capital and for general corporate purposes.

As of the date of this prospectus supplement, we cannot specify with certainty all of the particular uses of the proceeds, if any, from this offering. Accordingly, we will retain broad discretion over the use of such proceeds.

S-19

UNDERWRITING

Subject to the terms and conditions set forth in the underwriting agreement, dated the date of this prospectus supplement, among us and Clear Street LLC and Needham & Company, LLC, as the representatives of the underwriters named below and the joint book-running managers of this offering, we have agreed to sell to the underwriters, and each of the underwriters has agreed, severally and not jointly, to purchase from us, the respective number of shares of common stock shown opposite its name below:

	Number of Shares
Clear Street LLC		2,311,289
Needham & Company, LLC		1,540,860
Total		3,852,149

The underwriting agreement provides that the obligations of the several underwriters are subject to certain conditions precedent such as the receipt by the underwriters of officers’ certificates and legal opinions and approval of certain legal matters by their counsel. The underwriting agreement provides that the underwriters will purchase all of the shares of common stock. If an underwriter defaults, the underwriting agreement provides that the purchase commitments of the non-defaulting underwriters may be increased or the underwriting agreement may be terminated. We have agreed to indemnify the underwriters and certain of their controlling persons against certain liabilities, including liabilities under the Securities Act, and to contribute to payments that the underwriters may be required to make in respect of those liabilities.

The underwriters have advised us that, following the completion of this offering, they currently intend to make a market in the common stock as permitted by applicable laws and regulations. However, the underwriters are not obligated to do so, and the underwriters may discontinue any market-making activities at any time without notice in their sole discretion. Accordingly, no assurance can be given as to the liquidity of the trading market for the common stock, that you will be able to sell any of the common stock held by you at a particular time or that the prices that you receive when you sell will be favorable.

The underwriters are offering the shares of common stock subject to their acceptance of the shares of common stock and subject to prior sale. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part. In addition, the underwriters have advised us that they do not intend to confirm sales to any account over which they exercise discretionary authority except sales to accounts over which they have discretionary authority to exceed 5% of the common stock being offered.

Commission and Expenses

The underwriters have advised us that they propose to offer the shares of common stock to the public at the initial public offering prices set forth on the cover page of this prospectus supplement and to certain dealers, which may include the underwriters, at that price less a concession not in excess of $0.117 per share of common stock. After the offering, the public offering prices and concession to dealers may be reduced by the representatives. No such reduction will change the amount of proceeds to be received by us as set forth on the cover page of this prospectus supplement.

S-20

The following table shows the public offering price, the underwriting discounts and commissions that we are to pay the underwriters and the proceeds, before expenses, to us in connection with this offering.

	Per Share		Total
Public offering price	$	3.90	$	15,023,381.10
Underwriting discounts and commissions	$	0.234	$	901,402.87
Proceeds, before expenses, to us	$	3.666	$	14,121,978.23

Shares sold by the underwriters to the public will be offered at the public offering prices set forth on the cover of this prospectus supplement. Any securities sold by the underwriters to securities dealers may be sold at a discount of up to $0.117 per share from the public offering price. After the initial offering of the shares, the representatives may change the offering price and the other selling terms. The offering of the shares by the underwriters is subject to receipt and acceptance and subject to the underwriters’ right to reject any order in whole or in part. Sales of securities made outside of the United States may be made by affiliates of the underwriters.

We have also agreed to pay certain of the underwriters’ expenses relating to the offering, including the fees of outside counsel to the Underwriters up to an aggregate of $150,000, the costs and expenses of the Company relating to investor presentations on any “road show” undertaken in connection with the marketing of the offering, and all other third-party costs and expenses incident to the offering or the performance of the obligations of the Company under the Underwriting Agreement.

We estimate that our share of the total expenses of the offering, excluding underwriting discounts and commissions, will be approximately $0.5 million.

Lock-up Agreements

We, our executive officers and directors and certain of our other existing security holders have agreed not to sell or transfer any common stock or securities convertible into or exchangeable or exercisable for common stock, for 90 days after the date of the underwriting agreement without first obtaining the written consent of Clear Street LLC and Needham & Company. Specifically, we and these other persons have agreed, with certain limited exceptions, not to directly or indirectly:

● offer, pledge or contract to sell any common stock;

● sell any option or contract to purchase any common stock;

● purchase any option or contract to sell any common stock;

● grant any option, right or warrant for the sale of any common stock;

● otherwise dispose of or transfer any common stock;

● request or demand that we file a registration statement related to the common stock; or

● enter into any swap or other agreement or any transaction that transfers, in whole or in part, directly or indirectly, the economic consequence of ownership of any common stock, whether any such swap or transaction is to be settled by delivery or other securities, in cash or otherwise.

The lock-up provisions apply to common stock and to securities convertible into or exchangeable or exercisable for common stock. They also apply to Common Stock owned now or acquired later by the person executing the lock-up agreement or for which the person executing the lock-up agreement later acquires the power of disposition.

S-21

Determination of Offering Price

The public offering price for our common stock was determined by negotiations between us and the representatives. Among the factors considered in these negotiations were prevailing market conditions, our financial information, market valuations of other companies that we and the underwriters believe to be comparable to us, estimates of our business potential, the present state of our development and other factors deemed relevant.

We offer no assurances that the public offering prices will correspond to the price at which the common stock will trade in the public market subsequent to the offering or that an active trading market for the common stock will develop and continue after the offering.

Listing

Our common stock is listed on the Nasdaq Capital Market under the symbol “BSGM.”

Stabilization

The underwriters have advised us that they, pursuant to Regulation M under the Exchange Act, and certain persons participating in the offering may engage in short sale transactions, stabilizing transactions, syndicate covering transactions or the imposition of penalty bids in connection with this offering. These activities may have the effect of stabilizing or maintaining the market price of the common stock at a level above that which might otherwise prevail in the open market. Establishing short sales positions may involve “naked” short sales.

The underwriters must close out any naked short position by purchasing shares in the open market. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the shares of our common stock in the open market after pricing that could adversely affect investors who purchase in this offering.

S-22

A stabilizing bid is a bid for the purchase of shares of common stock on behalf of the underwriters for the purpose of fixing or maintaining the price of the common stock. A syndicate covering transaction is the bid for or the purchase of shares of common stock on behalf of the underwriters to reduce a short position incurred by the underwriters in connection with the offering. Similar to other purchase transactions, the underwriters’ purchases to cover the syndicate short sales may have the effect of raising or maintaining the market price of our common stock or preventing or retarding a decline in the market price of our common stock. As a result, the price of our common stock may be higher than the price that might otherwise exist in the open market. A penalty bid is an arrangement permitting the underwriters to reclaim the selling concession otherwise accruing to a syndicate member in connection with the offering if the common stock originally sold by such syndicate member are purchased in a syndicate covering transaction and therefore have not been effectively placed by such syndicate member.

Neither we, nor any of the underwriters, make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of our common stock. The underwriters are not obligated to engage in these activities and, if commenced, any of the activities may be discontinued at any time.

Electronic Distribution

A prospectus in electronic format may be made available by e-mail or on the web sites or through online services maintained by one or more of the underwriters or their affiliates. In those cases, prospective investors may view offering terms online and may be allowed to place orders online. The underwriters may agree with us to allocate a specific number of shares of common stock for sale to online brokerage account holders. Any such allocation for online distributions will be made by the underwriters on the same basis as other allocations. Other than the prospectus in electronic format, the information on the underwriters’ web sites and any information contained in any other web site maintained by any of the underwriters is not part of this prospectus, has not been approved and/or endorsed by us or the underwriters and should not be relied upon by investors.

Other Activities and Relationships

The underwriters and certain of their affiliates are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, investment research, principal investment, hedging, financing and brokerage activities.

The underwriters and certain of their affiliates have, from time to time, performed, and may in the future perform, various commercial and investment banking and financial advisory services for us and our affiliates, for which they received or will receive customary fees and expenses.

In the ordinary course of their various business activities, the underwriters and certain of their affiliates and employees may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments for their own account and for the accounts of their customers, and such investment and securities activities may involve securities and/or instruments issued by us and our affiliates. The underwriters and their respective affiliates may hedge such exposure by entering into transactions which consist of the creation of short positions in our securities or the securities of our affiliates, including potentially the common stock offered hereby. Any such short positions could adversely affect future trading prices of the common stock offered hereby. The underwriters and certain of their respective affiliates may also communicate independent investment recommendations, market color or trading ideas and/or publish or express independent research views in respect of such securities or instruments and may at any time hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

This prospectus provides you with a general description of the securities we may offer. Each time we sell securities, we will provide a prospectus supplement that will contain specific information about the terms of that offering. The prospectus supplement may also add to, update or change information contained in the prospectus and, accordingly, to the extent inconsistent, information in this prospectus is superseded by the information in the prospectus supplement.

The prospectus supplement to be attached to the front of this prospectus may describe, as applicable: the terms of the securities offered; the public offering price; the price paid for the securities; net proceeds; and the other specific terms related to the offering of the securities.

No person has been authorized to give any information or make any representations in connection with this offering other than those contained or incorporated by reference in this prospectus, any accompanying prospectus supplement and any related issuer free writing prospectus in connection with the offering described herein and therein, and, if given or made, such information or representations must not be relied upon as having been authorized by us. Neither this prospectus nor any prospectus supplement nor any related issuer free writing prospectus shall constitute an offer to sell or a solicitation of an offer to buy offered securities in any jurisdiction in which it is unlawful for such person to make such an offering or solicitation.

Overview

BioSig Technologies, Inc. is a medical device company with an advanced digital signal processing technology platform to deliver insights to the treatment of cardiovascular arrhythmias. Through collaboration with physicians, experts, and healthcare leaders across the field of electrophysiology (EP), we are committed to addressing healthcare’s biggest priorities — saving time, saving costs, and saving lives.

Our first product, the PURE EP™ System, is an FDA 510(k) cleared non-invasive class II device consisting of a unique combination of hardware and software designed to provide unprecedented signal clarity and precision for real-time visualization of intracardiac signals paving the way for personalized patient care. Integrating with existing systems in the EP lab, PURE EP™ is designed to accurately pinpoint even the most complex signals to maximize procedural success and efficiency.

By capturing critical cardiac signals—even the most complex, the PURE EP™ System is designed to enhance clinical decision-making and improve clinical workflow for all types of arrhythmias - even the most challenging procedures for cardiac arrhythmias, like ventricular tachycardia (VT) and atrial fibrillation (AF).

Our owned patent portfolio now includes 41 issued/allowed utility patents (29 utility patents where BioSig is at least one of the applicants). Twenty seven additional U.S. and foreign utility patent applications are pending covering various aspects of our PURE EP System for recording, measuring, calculating and displaying of electrocardiograms during cardiac ablation procedures (27 U.S. and foreign utility patent applications where either BioSig, Mayo, or both is at least one of the applicants). We also have one U.S. patent and one U.S. Pending application directed to artificial intelligence (AI). We also have 30 issued worldwide design patents, which cover various features of our display screens and graphical user interface for enhanced visualization of biomedical signals (30 design patents where BioSig is at least one of the applicants). Finally, we have licenses to 12 (issued/allowed) patents and 9 additional worldwide utility patent applications from Mayo Foundation for Medical Education and Research that are pending (12 issued/allowed patents and 9 applications where only Mayo is the applicant). These patents and applications are generally directed to electroporation and stimulation.

The Securities We May Offer

We may offer up to $75,000,000 of common stock, preferred stock, warrants and/or units in one or more offerings and in any combination. This prospectus provides you with a general description of the securities we may offer. A prospectus supplement, which we will provide each time we offer securities, will describe the specific amounts, prices and terms of these securities.

Common Stock

We may issue shares of our common stock from time to time. Holders of our common stock are entitled to receive ratably dividends as may be declared by the board of directors out of funds legally available for that purpose. We have never paid cash dividends on our common stock and do not anticipate paying any cash dividends in the foreseeable future but intend to retain our capital resources for reinvestment in our business. Any future disposition of dividends will be at the discretion of our board of directors and will depend upon, among other things, our future earnings, operating and financial condition, capital requirements, and other factors.

Each share of common stock entitles the holder to one vote, either in person or by proxy, at meetings of stockholders. The holders are not permitted to vote their shares cumulatively. Accordingly, the stockholders of our common stock who hold, in the aggregate, more than fifty percent of the total voting rights can elect all of our directors and, in such event, the holders of the remaining minority shares will not be able to elect any of such directors. The affirmative vote of the holders of a majority in voting power of the votes cast (excluding abstentions and broker non-votes) on any matter other than the election of directors that is presented to stockholders at a duly called or convened meeting at which a quorum is present is sufficient to authorize, affirm, ratify or consent to such act or action, except as otherwise provided by our certificate of incorporation, our bylaws, the rules or regulations of any stock exchange applicable to us, or applicable law or pursuant to any regulation applicable to us or our securities.

Holders of our common stock have no preemptive rights or other subscription rights, conversion rights, redemption or sinking fund provisions. Subject to the rights of the holders of our preferred stock, upon our liquidation, dissolution or winding up, the holders of our common stock will be entitled to share ratably in the net assets legally available for distribution to stockholders after the payment of all of our debts and other liabilities. The rights, preferences and privileges of holders of our common stock are subject to, and may be adversely affected by, the rights of the holders of any series of preferred stock, which may be designated solely by action of our board of directors and issued in the future.

Preferred Stock

We may issue shares of our preferred stock from time to time, in one or more series. Our board of directors will determine the rights, preferences, privileges and restrictions of the preferred stock, including dividend rights, conversion rights, voting rights, terms of redemption, liquidation preferences, sinking fund terms and the number of shares constituting any series or the designation of such series, without any further vote or action by stockholders. Convertible preferred stock will be convertible into our common stock or exchangeable for our other securities. Conversion may be mandatory or at your option or both and would be at prescribed conversion rates.

If we sell any series of preferred stock under this prospectus and applicable prospectus supplements, we will fix the rights, preferences, privileges and restrictions of the preferred stock of such series in the certificate of designation relating to that series. We will file as an exhibit to the registration statement of which this prospectus is a part, or will incorporate by reference from reports that we file with the SEC, the form of any certificate of designation that describes the terms of the series of preferred stock we are offering before the issuance of the related series of preferred stock. We urge you to read the applicable prospectus supplement related to the series of preferred stock being offered, as well as the complete certificate of designation that contains the terms of the applicable series of preferred stock.

Warrants

We may issue warrants for the purchase of common stock or preferred stock in one or more series. We may issue warrants independently or together with common stock or preferred stock, and the warrants may be attached to or separate from these securities. We will evidence each series of warrants by warrant certificates that we will issue under a separate agreement. We may enter into warrant agreements with a bank or trust company that we select to be our warrant agent. We will indicate the name and address of the warrant agent in the applicable prospectus supplement relating to a particular series of warrants.

In this prospectus, we have summarized certain general features of the warrants. We urge you, however, to read the applicable prospectus supplement related to the particular series of warrants being offered, as well as the warrant agreements and warrant certificates that contain the terms of the warrants. We will file as exhibits to the registration statement of which this prospectus is a part, or will incorporate by reference from reports that we file with the SEC, the form of warrant agreement or warrant certificate containing the terms of the warrants we are offering before the issuance of the warrants.

Units

We may issue units consisting of common stock, preferred stock and/or warrants for the purchase of common stock or preferred stock in one or more series. In this prospectus, we have summarized certain general features of the units. We urge you, however, to read the applicable prospectus supplement related to the series of units being offered, as well as the unit agreements that contain the terms of the units. We will file as exhibits to the registration statement of which this prospectus is a part, or will incorporate by reference reports that we file with the SEC, the form of unit agreement and any supplemental agreements that describe the terms of the series of units we are offering before the issuance of the related series of units.

RISK FACTORS

An investment in our securities involves a high degree of risk. Before deciding whether to invest in our securities, you should consider carefully the specific factors discussed under the heading “Risk Factors” in the applicable prospectus supplement, together with all of the other information contained or incorporated by reference in the prospectus supplement or appearing or incorporated by reference in this prospectus. You should also consider the risks, uncertainties and assumptions discussed under Part I, Item 1A, “Risk Factors,” in our most recent Annual Report on Form 10-K or any updates in our Quarterly Reports on Form 10-Q, which are incorporated herein by reference, as updated or superseded by the risks and uncertainties described under similar headings in the other documents that are filed after the date hereof and incorporated by reference into this prospectus and any prospectus supplement related to a particular offering. The risks and uncertainties we have described are not the only ones we face. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also affect our operations. Past financial performance may not be a reliable indicator of future performance, and historical trends should not be used to anticipate results or trends in future periods. If any of these risks actually occurs, our business, business prospects, financial condition or 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. Please also read carefully the section above entitled “Cautionary Statement Regarding Forward-Looking Statements.”

USE OF PROCEEDS

We cannot assure you that we will receive any proceeds in connection with securities which may be offered pursuant to this prospectus. Unless otherwise indicated in the applicable prospectus supplement, we intend to use any net proceeds from the sale of securities under this prospectus for our operations and for other general corporate purposes, including, but not limited to, general working capital and possible future acquisitions. We have not determined the amounts we plan to spend on any of the areas listed above or the timing of these expenditures. As a result, our management will have broad discretion to allocate the net proceeds, if any, we receive in connection with securities offered pursuant to this prospectus for any purpose. Pending application of the net proceeds as described above, we may initially invest the net proceeds in investment-grade, interest-bearing securities such as money market funds, certificates of deposit, or direct or guaranteed obligations of the U.S. government, hold as cash or apply them to the reduction of short-term indebtedness.

DESCRIPTION OF CAPITAL STOCK

The following description of common stock and preferred stock summarizes the material terms and provisions of the common stock and preferred stock that we may offer under this prospectus, but is not complete. For the complete terms of our common stock and preferred stock, please refer to our amended and restated certificate of incorporation, as amended, any certificates of designation for our preferred stock, and our amended and restated bylaws, as amended. While the terms we have summarized below will apply generally to any future common stock or preferred stock that we may offer, we will describe the specific terms of any series of preferred stock in more detail in the applicable prospectus supplement. If we so indicate in a prospectus supplement, the terms of any preferred stock we offer under that prospectus supplement may differ from the terms we describe below.

We have authorized 201,000,000 shares of capital stock, par value $0.001 per share, of which 200,000,000 are shares of common stock and 1,000,000 are shares of “blank check” preferred stock, of which 200 are authorized as Series A Preferred Stock, 600 are authorized as Series B Preferred Stock, 4,200 are authorized as Series C Preferred Stock, 1,400 are authorized as Series D Preferred Stock, 1,000 are authorized as Series E Preferred Stock and 200,000 are authorized as Series F Junior Participating Preferred Stock. As of December 9, 2024, there were 17,234,929 shares of common stock issued and outstanding, 105 shares of Series C Preferred Stock issued and outstanding and no shares of our Series A Convertible Preferred Stock, Series B Convertible Preferred Stock, Series D Convertible Preferred Stock, Series E Convertible Preferred Stock or Series F Junior Participating Preferred Stock issued and outstanding. The authorized and unissued shares of common stock and the authorized and undesignated shares of preferred stock are available for issuance without further action by our stockholders, unless such action is required by applicable law or the rules of any stock exchange on which our securities may be listed. Unless approval of our stockholders is so required, our board of directors does not intend to seek stockholder approval for the issuance and sale of our common stock or preferred stock.

Common Stock

The holders of common stock are entitled to one vote per share on all matters to be voted upon by stockholders. Holders of our common stock are entitled to receive ratably dividends as may be declared by the board of directors out of funds legally available for that purpose. We have never paid cash dividends on our common stock and do not anticipate paying any cash dividends in the foreseeable future but intend to retain our capital resources for reinvestment in our business. Any future disposition of dividends will be at the discretion of our board of directors and will depend upon, among other things, our future earnings, operating and financial condition, capital requirements, and other factors.

The transfer agent and registrar for our common stock is Securities Transfer Corporation. The transfer agent’s address is 2901 N. Dallas Parkway, Suite 380, Plano, TX 75093. Our common stock is listed on The Nasdaq Capital Market under the symbol “BSGM.”

Preferred Stock

The board of directors is authorized, subject to any limitations prescribed by law, without further vote or action by the stockholders, to issue from time to time shares of preferred stock in one or more series. Each such series of preferred stock shall have such number of shares, designations, preferences, voting powers, qualifications, and special or relative rights or privileges as shall be determined by the board of directors, which may include, among others, dividend rights, voting rights, liquidation preferences, conversion rights and preemptive rights. Issuance of preferred stock by our board of directors may result in such shares having dividend and/or liquidation preferences senior to the rights of the holders of our common stock and could dilute the voting rights of the holders of our common stock.

Prior to the issuance of shares of each series of preferred stock, the board of directors is required by the Delaware General Corporation Law (the “DGCL”) and our certificate of incorporation to adopt resolutions and file a certificate of designation with the Secretary of State of the State of Delaware. The certificate of designation fixes for each class or series the designations, powers, preferences, rights, qualifications, limitations and restrictions, including, but not limited to, some or all of the following:

	●	the number of shares constituting that series and the distinctive designation of that series, which number may be increased or decreased (but not below the number of shares then outstanding) from time to time by action of the board of directors;

	●	the dividend rate and the manner and frequency of payment of dividends on the shares of that series, whether dividends will be cumulative, and, if so, from which date;

	●	whether that series will have voting rights, in addition to any voting rights provided by law, and, if so, the terms of such voting rights;

	●	whether that series will have conversion privileges, and, if so, the terms and conditions of such conversion, including provision for adjustment of the conversion rate in such events as the board of directors may determine;

	●	whether or not the shares of that series will be redeemable, and, if so, the terms and conditions of such redemption;

	●	whether that series will have a sinking fund for the redemption or purchase of shares of that series, and, if so, the terms and amount of such sinking fund;

	●	whether or not the shares of the series will have priority over or be on a parity with or be junior to the shares of any other series or class in any respect;

	●	the rights of the shares of that series in the event of voluntary or involuntary liquidation, dissolution or winding up of the corporation, and the relative rights or priority, if any, of payment of shares of that series; and

	●	any other relative rights, preferences and limitations of that series.

Once designated by our board of directors, each series of preferred stock may have specific financial and other terms that will be described in a prospectus supplement. The description of the preferred stock that is set forth in any prospectus supplement is not complete without reference to the documents that govern the preferred stock. These include our certificate of incorporation and any certificates of designation that our board of directors may adopt.

All shares of preferred stock offered hereby will, when issued, be fully paid and nonassessable, including shares of preferred stock issued upon the exercise of preferred stock warrants or subscription rights, if any.

Although our board of directors has no intention at the present time of doing so, it could authorize the issuance of a series of preferred stock that could, depending on the terms of such series, impede the completion of a merger, tender offer or other takeover attempt.

Anti-Takeover Effects of Certain Provisions of Delaware Law, our Certificate of Incorporation and Bylaws

Delaware Law

We are subject to Section 203 of the DGCL. Section 203 generally prohibits a public Delaware corporation from engaging in a “business combination” with an “interested stockholder” for a period of three years after the date of the transaction in which the person became an interested stockholder, unless:

	●	prior to the date of the transaction, the board of directors of the corporation approved either the business combination or 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 number of shares outstanding (but not the outstanding voting stock owned by the interested stockholder) (i) shares owned by persons who are directors and also officers and (ii) shares owned by 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

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

Section 203 defines a business combination to include:

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

	●	any sale, transfer, pledge or other disposition involving the interested stockholder of 10% or more of the assets of the corporation;

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

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

In general, Section 203 defines an “interested stockholder” as any entity or person beneficially owning 15% or more of the outstanding voting stock of the corporation and any entity or person affiliated with, or controlling, or controlled by, the entity or person. The term “owner” is broadly defined to include any person that, individually, with or through that person’s affiliates or associates, among other things, beneficially owns the stock, or has the right to acquire the stock, whether or not the right is immediately exercisable, under any agreement or understanding or upon the exercise of warrants or options or otherwise or has the right to vote the stock under any agreement or understanding, or has an agreement or understanding with the beneficial owner of the stock for the purpose of acquiring, holding, voting or disposing of the stock.

The restrictions in Section 203 do not apply to corporations that have elected, in the manner provided in Section 203, not to be subject to Section 203 of the DGCL or, with certain exceptions, which do not have a class of voting stock that is listed on a national securities exchange or held of record by more than 2,000 stockholders. Our certificate of incorporation and bylaws do not opt out of Section 203.

Section 203 could delay or prohibit mergers or other takeover or change in control attempts with respect to us and, accordingly, may discourage attempts to acquire us even though such a transaction may offer our stockholders the opportunity to sell their stock at a price above the prevailing market price.

Certificate of Incorporation and Bylaws

Provisions of our certificate of incorporation and bylaws may delay or discourage transactions involving an actual or potential change in our control or change in our management, including transactions in which stockholders might otherwise receive a premium for their shares, or transactions that our stockholders might otherwise deem to be in their best interests. Therefore, these provisions could adversely affect the price of our common stock. Among other things, our certificate of incorporation and bylaws:

	●	permit our board of directors to issue up to 1,000,000 shares of preferred stock, without further action by the stockholders, with any rights, preferences and privileges as they may designate, including the right to approve an acquisition or other change in control;

	●	provide that the authorized number of directors may be changed only by a resolution adopted by a majority of the total number of authorized directors;

	●	do not provide for cumulative voting rights (therefore allowing the holders of a majority of the shares of common stock entitled to vote in any election of directors to elect all of the directors standing for election, if they should so choose); and

	●	provide advance notice provisions with which a stockholder who wishes to nominate a director or propose other business to be considered at a stockholder meeting must comply.

DESCRIPTION OF WARRANTS

As of December 9, 2024, there were outstanding warrants to purchase 4,899,716 shares of common stock.

We will evidence each series of warrants by warrant certificates that we may issue under a separate agreement. We may enter into a warrant agreement with a warrant agent. Each warrant agent may be a bank that we select which has its principal office in the United States. We may also choose to act as our own warrant agent. We will indicate the name and address of any such warrant agent in the applicable prospectus supplement relating to a particular series of warrants.

We will describe in the applicable prospectus supplement the terms of the series of warrants, including:

	●	the offering price and aggregate number of warrants offered;

	●	if applicable, the designation and terms of the securities with which the warrants are issued and the number of warrants issued with each such security or each principal amount of such security;

	●	if applicable, the date on and after which the warrants and the related securities will be separately transferable;

	●	in the case of warrants to purchase common stock or preferred stock, the number or amount of shares of common stock or preferred stock, as the case may be, purchasable upon the exercise of one warrant and the price at which and currency in which these shares may be purchased upon such exercise;

	●	the manner of exercise of the warrants, including any cashless exercise rights;

	●	the warrant agreement under which the warrants will be issued;

	●	the effect of any merger, consolidation, sale or other disposition of our business on the warrant agreement and the warrants;

	●	anti-dilution provisions of the warrants, if any;

	●	the terms of any rights to redeem or call the warrants;

	●	any provisions for changes to or adjustments in the exercise price or number of securities issuable upon exercise of the warrants;

	●	the dates on which the right to exercise the warrants will commence and expire or, if the warrants are not continuously exercisable during that period, the specific date or dates on which the warrants will be exercisable;

	●	the manner in which the warrant agreement and warrants may be modified;

	●	the identities of the warrant agent and any calculation or other agent for the warrants;

	●	federal income tax consequences of holding or exercising the warrants;

	●	the terms of the securities issuable upon exercise of the warrants;

	●	any securities exchange or quotation system on which the warrants or any securities deliverable upon exercise of the warrants may be listed or quoted; and

	●	any other specific terms, preferences, rights or limitations of or restrictions on the warrants.

Before exercising their warrants, holders of warrants will not have any of the rights of holders of the securities purchasable upon such exercise, including, in the case of warrants to purchase common stock or preferred stock, the right to receive dividends, if any, or payments upon our liquidation, dissolution or winding up or to exercise voting rights, if any.

Exercise of Warrants

Each warrant will entitle the holder to purchase the securities that we specify in the applicable prospectus supplement at the exercise price that we describe in the applicable prospectus supplement. Unless we otherwise specify in the applicable prospectus supplement, holders of the warrants may exercise the warrants at any time up to 5:00 P.M. Eastern Time, the close of business, on the expiration date that we set forth in the applicable prospectus supplement. After the close of business on the expiration date, unexercised warrants will become void.

Holders of the warrants may exercise the warrants by delivering the warrant certificate representing the warrants to be exercised together with specified information, and paying the required exercise price by the methods provided in the applicable prospectus supplement. We will set forth on the reverse side of the warrant certificate, and in the applicable prospectus supplement, the information that the holder of the warrant will be required to deliver to the warrant agent.

Upon receipt of the required payment and the warrant certificate properly completed and duly executed at the corporate trust office of the warrant agent or any other office indicated in the applicable prospectus supplement, we will issue and deliver the securities purchasable upon such exercise. If fewer than all of the warrants represented by the warrant certificate are exercised, then we will issue a new warrant certificate for the remaining amount of warrants.

Enforceability of Rights by Holders of Warrants

Any warrant agent will act solely as our agent under the applicable warrant agreement and will not assume any obligation or relationship of agency or trust with any holder of any warrant. A single bank or trust company may act as warrant agent for more than one issue of warrants. A warrant agent will have no duty or responsibility in case of any default by us under the applicable warrant agreement or warrant, including any duty or responsibility to initiate any proceedings at law or otherwise, or to make any demand upon us. Any holder of a warrant may, without the consent of the related warrant agent or the holder of any other warrant, enforce by appropriate legal action the holder’s right to exercise, and receive the securities purchasable upon exercise of, its warrants in accordance with their terms.

Warrant Agreement Will Not Be Qualified Under Trust Indenture Act

No warrant agreement will be qualified as an indenture, and no warrant agent will be required to qualify as a trustee, under the Trust Indenture Act of 1939. Therefore, holders of warrants issued under a warrant agreement will not have the protection of the Trust Indenture Act of 1939 with respect to their warrants.

Governing Law

Unless we provide otherwise in the applicable prospectus supplement, each warrant agreement and any warrants issued under the warrant agreements will be governed by New York law.

DESCRIPTION OF UNITS

We may issue units comprised of one or more of the other securities described in this prospectus or any prospectus supplement in any combination. Each unit will be issued so that the holder of the unit is also the holder, with the rights and obligations of a holder, of each security included in the unit. The unit agreement under which a unit is issued may provide that the securities included in the unit may not be held or transferred separately, at any time or at any times before a specified date or upon the occurrence of a specified event or occurrence.

The applicable prospectus supplement will describe:

	●	the designation and the terms of the units and of the securities comprising the units, including whether and under what circumstances those securities may be held or transferred separately;

	●	any unit agreement under which the units will be issued;

	●	any provisions for the issuance, payment, settlement, transfer or exchange of the units or of the securities comprising the units; and

	●	whether the units will be issued in fully registered or global form.

PLAN OF DISTRIBUTION

We may sell the securities offered pursuant to this prospectus from time to time in one or more transactions, including, without limitation:

	●	to or through underwriters;

	●	through broker-dealers (acting as agent or principal);

	●	through agents;

	●	ordinary brokerage transactions and transactions in which a broker-dealer solicits purchasers;

	●	sales “at the market” to or through a market maker or into an existing trading market, on an exchange or otherwise; and

	●	sales in other ways not involving market makers or established trading markets, including direct sales to purchasers.

The applicable prospectus supplement or free writing prospectus will describe the terms of the offering of the securities, including:

	●	the name or names of any underwriters, if, and if required, any dealers or agents;

	●	the purchase price of the securities and the proceeds we will receive from the sale;

	●	any underwriting discounts and other items constituting underwriters’ compensation;

	●	a fixed price or prices, which may be changed;

	●	market prices prevailing at the time of sale;

	●	prices related to such prevailing market prices; or

	●	negotiated prices.

Only underwriters named in the prospectus supplement are underwriters of the securities offered by the prospectus supplement.

If underwriters are used in an offering, we will execute an underwriting agreement with such underwriters and will specify the name of each underwriter and the terms of the transaction (including any underwriting discounts and other terms constituting compensation of the underwriters and any dealers) in a prospectus supplement. The securities may be offered to the public either through underwriting syndicates represented by managing underwriters or directly by one or more investment banking firms or others, as designated. If an underwriting syndicate is used, the managing underwriter(s) will be specified on the cover of the prospectus supplement. If underwriters are used in the sale, the offered securities will be acquired by the underwriters for their own accounts and may be resold from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. Any public offering price and any discounts or concessions allowed or reallowed or paid to dealers may be changed from time to time. Unless otherwise set forth in the prospectus supplement, the obligations of the underwriters to purchase the offered securities will be subject to conditions precedent, and the underwriters will be obligated to purchase all of the offered securities, if any are purchased.

We may grant to the underwriters options to purchase additional securities to cover over-allotments, if any, at the public offering price, with additional underwriting commissions or discounts, as may be set forth in a related prospectus supplement. The terms of any over-allotment option will be set forth in the prospectus supplement for those securities.

If we use a dealer in the sale of the securities being offered pursuant to this prospectus or any prospectus supplement, we will sell the securities to the dealer, as principal. The dealer may then resell the securities to the public at varying prices to be determined by the dealer at the time of resale. The names of the dealers and the terms of the transaction will be specified in a prospectus supplement.

We may sell the securities directly or through agents we designate from time to time. We will name any agent involved in the offering and sale of securities and we will describe any commissions we will pay the agent in the prospectus supplement. Unless the prospectus supplement states otherwise, any agent will act on a best-efforts basis for the period of its appointment.

We may authorize agents or underwriters to solicit offers by institutional investors to purchase securities from us at the public offering price set forth in the prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on a specified date in the future. We will describe the conditions to these contracts and the commissions we must pay for solicitation of these contracts in the prospectus supplement.

In connection with the sale of the securities, underwriters, dealers or agents may receive compensation from us or from purchasers of the securities for whom they act as agents, in the form of discounts, concessions or commissions. Underwriters may sell the securities to or through dealers, and those dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters or commissions from the purchasers for whom they may act as agents. Underwriters, dealers and agents that participate in the distribution of the securities, and any institutional investors or others that purchase securities directly for the purpose of resale or distribution, may be deemed to be underwriters, and any discounts or commissions received by them from us and any profit on the resale of the common stock by them may be deemed to be underwriting discounts and commissions under the Securities Act.

We may provide agents, underwriters and other purchasers with indemnification against particular civil liabilities, including liabilities under the Securities Act, or contribution with respect to payments that the agents, underwriters or other purchasers may make with respect to such liabilities. Agents and underwriters may engage in transactions with, or perform services for, us in the ordinary course of business.

To facilitate the public offering of a series of securities, persons participating in the offering may engage in transactions that stabilize, maintain, or otherwise affect the market price of the securities. This may include over-allotments or short sales of the securities, which involves the sale by persons participating in the offering of more securities than have been sold to them by us. In addition, those persons may stabilize or maintain the price of the securities by bidding for or purchasing securities in the open market or by imposing penalty bids, whereby selling concessions allowed to underwriters or dealers participating in any such offering may be reclaimed if securities sold by them are repurchased in connection with stabilization transactions. The effect of these transactions may be to stabilize or maintain the market price of the securities at a level above that which might otherwise prevail in the open market. Such transactions, if commenced, may be discontinued at any time. We make no representation or prediction as to the direction or magnitude of any effect that the transactions described above, if implemented, may have on the price of our securities.

Unless otherwise specified in the applicable prospectus supplement, any common stock sold pursuant to a prospectus supplement will be eligible for listing on The Nasdaq Capital Market, subject to official notice of issuance. Any underwriters to whom securities are sold by us for public offering and sale may make a market in the securities, but such underwriters will not be obligated to do so and may discontinue any market making at any time without notice.

In order to comply with the securities laws of some states, if applicable, the securities offered pursuant to this prospectus will be sold in those states only through registered or licensed brokers or dealers. In addition, in some states securities 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 complied with.
