Following the 2025 annual meeting, on June 6, 2025, the Company filed the Share Increase Amendment with the Secretary of State.

As of March 31, 2026, the Company’s authorized capital stock consisted of 1,300,000,000 shares, of which 1,250,000,000 are shares of Common Stock, and 50,000,000 are shares of preferred stock, $0.001 par value per share, 1,990,000 of which have been designated as Series C Convertible Preferred Stock (the “Series C Preferred Stock”), 211,353 of which have been designated as Series D Convertible Preferred Stock (the “Series D Preferred Stock”), 100,000 of which have been designated as Series E Junior Participating Preferred Stock, 15,000 of which have been designated as Series F Preferred Shares, 5,050 of which have been designated as Series F-1 Convertible Preferred Stock, 12,826,273 of which have been designated as Series G Preferred Stock, 7,000 of which have been designated as Series H Preferred Stock, and 747,362 of which have been designated as Series I Preferred Stock.

Preferred Stock

The holders of preferred shares or preferred warrants are entitled to vote, as determined and as limited by the certificate of designation for each class of preferred shares or warrants, at meetings of the Company stockholders.

Series D Convertible Preferred Stock

The following are the principal terms of the Series D Preferred Stock:

Rank

The Series D Preferred Stock ranks (1) on parity with Common Stock on an “as converted” basis, (2) senior to any series of the Company’s capital stock hereafter created specifically ranking by its terms junior to the Series D Preferred Stock, (3) on parity with any series of the Company’s capital stock hereafter created specifically ranking by its terms on parity with the Series D Preferred Stock, and (4) junior to any series of the Company’s capital stock hereafter created specifically ranking by its terms senior to the Series D Preferred Stock in each case, as to dividends or distributions of assets upon the Company’s liquidation, dissolution or winding up whether voluntary or involuntary.

Conversion Rights

A holder of Series D Preferred Stock is entitled at any time to convert any whole or partial number of shares of Series D Preferred Stock into shares of the Company’s Common Stock, determined by dividing the stated value equal to $0.01 by the conversion price of $0.01 per share. A holder of Series D Preferred Stock is prohibited from converting Series D Preferred Stock into shares of Common Stock if, as a result of such conversion, the holder, together with its affiliates, would own more than 4.99% of the total number of shares of the Company’s Common Stock then issued and outstanding (with such ownership restriction referred to as the “Series D Beneficial Ownership Limitation”) immediately after giving effect to the issuance of the shares of Common Stock issuable upon conversion of the Series D Preferred Stock. However, any holder may increase or decrease such percentage to any other percentage not in excess of 9.99%, provided that any increase in such percentage shall not be effective until 61 days after such notice to us. The conversion rate of the Series D Preferred Stock is subject to proportionate adjustments for stock splits, reverse stock splits and similar events, but is not subject to adjustment based on price anti-dilution provisions.

Dividend Rights

In addition to stock dividends or distributions for which proportionate adjustments will be made, holders of Series D Preferred Stock are entitled to receive dividends on shares of Series D Preferred Stock equal, on an as-if-converted-to-common-stock basis, to and in the same form as dividends actually paid on shares of the Common Stock when, as and if such dividends are paid on shares of the Common Stock. No other dividends are payable on shares of Series D Preferred Stock.

Voting Rights

Subject to the Series D Beneficial Ownership Limitation, on any matter presented to the Company’s stockholders for their action or consideration at any meeting of the Company’s stockholders (or by written consent of stockholders in lieu of a meeting), each holder, in its capacity as such, shall be entitled to cast the number of votes equal to the number of whole shares of the Company’s Common Stock into which the Series D Preferred Stock beneficially owned by such holder are convertible as of the record date for determining stockholders entitled to vote on or consent to such matter (taking into account all Series D Preferred Stock beneficially owned by such holder). Except as otherwise required by law or by the other provisions of the Certificate of Designation of Series D Convertible Preferred Stock (the “Series D Certificate of Designation”), the holders of Series D Preferred Stock, in their capacity as such, shall vote together with the holders of the Company’s Common Stock and any other class or series of stock entitled to vote thereon as a single class.

Liquidation Rights

Upon any liquidation, dissolution or winding-up of the Company, whether voluntary or involuntary, the holders of Series D Preferred Stock are entitled to receive, pari passu with the holders of Common Stock, out of the assets available for distribution to stockholders an amount equal to such amount per share as would have been payable had all shares of Series D Preferred Stock been converted into Common Stock immediately before such liquidation, dissolution or winding up, without giving effect to any limitation on conversion as a result of the Series D Beneficial Ownership Limitation, as described above.

Failure to Deliver Conversion Shares

If the Company fails to timely deliver shares of Common Stock upon conversion of the Series D Preferred Stock (the “Series D Conversion Shares”) within the time period specified in the Series D Certificate of Designation (within two trading days after delivery of the notice of conversion, or any shorter standard settlement period in effect with respect to trading market on the date notice is delivered), then the Company is obligated to pay to the holder, as liquidated damages, an amount equal to $25 per trading day (increasing to $50 per trading day on the third trading day and $100 per trading day on the sixth trading day) for each $5,000 of stated value of Series D Preferred Stock being converted which are not timely delivered. If the Company makes such liquidated damages payments, the Company is also not obligated to make Series D Buy-In (as defined below) payments with respect to the same Series D Conversion Shares.

Compensation for Series D Buy-In on Failure to Timely Deliver Shares

If the Company fails to timely deliver the Series D Conversion Shares to the holder, and if after the required delivery date the holder is required by its broker to purchase (in an open market transaction or otherwise) or the holder or its brokerage firm otherwise purchases, shares of Common Stock to deliver in satisfaction of a sale by the holder of the Series D Conversion Shares which the holder anticipated receiving upon such conversion or exercise (a “Series D Buy-In”), then the Company is obligated to (A) pay in cash to such holder (in addition to any other remedies available to or elected by such holder) the amount, if any, by which (x) such holder’s total purchase price (including any brokerage commissions) for the shares of Common Stock so purchased exceeds (y) the product of (1) the aggregate number of Series D Conversion Shares that such holder was entitled to receive from the conversion at issue multiplied by (2) the actual sale price at which the sell order giving rise to such purchase obligation was executed (including any brokerage commissions) and (B) at the option of such holder, either reissue (if surrendered) the shares of Series D Preferred Stock equal to the number of shares of Series D Preferred Stock submitted for conversion (in which case, such conversion shall be deemed rescinded) or deliver to such holder the number of Series D Conversion Shares that would have been issued if the Company had timely complied with its delivery requirements.

As of March 31, 2026 and December 31, 2025, the Company had 72,992 shares of Series D Convertible Preferred Stock outstanding which represent 13 underlying shares of the Company’s Common Stock.

Series F Convertible Preferred Stock

On February 21, 2023, the Company entered into a Securities Purchase Agreement (the “Series F Purchase Agreement”) with certain accredited investors (the “Series F Investors”), pursuant to which it agreed to sell to the Series F Investors (i) an aggregate of 15,000 shares of the Company’s newly-designated Series F convertible preferred stock (the “Series F Preferred Shares”) with a stated value of $1,000 per share, initially convertible into up to 66,523 shares of the Company’s Common Stock at an initial conversion price of $6,765 per share (the “Series F Conversion Price”), subject to adjustment, and (ii) warrants to acquire up to an aggregate of 66,523 shares of the Company’s Common Stock, subject to adjustment (the “Series F Warrants”) (collectively, the “February 2023 Offering”). The Series F Preferred Shares became convertible upon issuance into Common Stock (the “Series F Conversion Shares”) at the election of the holder at any time at an initial conversion price of $225.50. The Series F Conversion Price is subject to customary adjustments for stock dividends, stock splits, reclassifications and the like, and subject to price-based adjustment in the event of any issuances of Common Stock, or securities convertible, exercisable or exchangeable for Common Stock, at a price below the then-applicable Series F Conversion Price (subject to certain exceptions).

Following the Company’s one-for-thirty reverse stock split of its Common Stock in February 2024 (the “2024 Reverse Stock Split”), the conversion price of the Series F Preferred Shares was adjusted to $318.00 per share pursuant to the terms of the Certificate of Designations of Series F Convertible Preferred Stock, which was subsequently amended and restated by the filing of the Amended and Restated Certificate of Designations of Series F Convertible Preferred Stock, effective April 8, 2024 and which was amended and restated by the filing of the Second Amended and Restated Certificate of Designations of Series F Convertible Preferred Stock, effective September 3, 2025 (as amended and restated, the “Series F Certificate of Designations”). In connection with the Private Placements (as defined herein), (i) the conversion price of the Series F Preferred Shares was further adjusted to $181.60 per share pursuant to the full ratchet anti-dilution provisions contained in the Series F Certificate of Designations. On April 17, 2025, in connection with the issuance of stock options to certain officers of the Company and pursuant to the full ratchet anti-dilution provisions contained in the Series F Certificate of Designations the Series F Conversion Price was adjusted to $18.32 per share. In September 2025, in connection with the Company’s 1-for-100 reverse stock split (the “2025 Reverse Stock Split”), and pursuant to the stock combination event adjustment provisions contained in the Series F Certificate of Designations, the Series F Conversion Price was reduced to $3.3713 per share.

Prior to the Series F Certificate of Amendment (as defined below), the Company was initially required to redeem the Series F Preferred Shares in 12 equal monthly installments, commencing on July 1, 2023. The amortization payments due upon such redemption are payable, at the Company’s election, in cash, or subject to certain limitations, in shares of Common Stock valued at the lower of (i) the Series F Conversion Price then in effect and (ii) the greater of (A) 80% of the average of the three lowest closing prices of the Company’s Common Stock during the thirty trading day period immediately prior to the date the amortization payment is due or (B) a “Floor Price” of $660.00 on a post-split basis (subject to adjustment for stock splits, stock dividends, stock combinations, recapitalizations or other similar events) or, in any case, such lower amount as permitted, from time to time, by the Nasdaq Stock Market.

On April 5, 2024, the Company entered into an Omnibus Waiver and Amendment (the “Omnibus Agreement”) with the Required Holders (as defined in the Series F Certificate of Designations). Pursuant to the Omnibus Agreement, the Required Holders agreed (i) to defer payment of the monthly installment amounts due on March 1, 2024, and April 1, 2024 (the “Installments”), under Section 9(a) of the Series F Certificate of Designations, until May 1, 2024, and (ii) to waive any breach or violation of the Series F Purchase Agreement, the Series F Certificate of Designations, or the Series F Warrants resulting from missing the Installments. The Company may require holders to convert their Series F Preferred Shares into shares of Common Stock if the closing price of the Common Stock exceeds $6.765 per share (as adjusted for the 2025 Reverse Stock Split) (subject to adjustment for stock splits, stock dividends, stock combinations, recapitalizations or other similar events) for 20 consecutive trading days and the daily dollar trading volume of the Common Stock exceeds $3,000,000 per day during the same period and certain equity conditions described in the Series F Certificate of Designations are satisfied.

On August 19, 2025, the Company entered into an Omnibus Amendment Agreement (“August 2025 Amendment Agreement”) with the Required Holders (as defined in the Series F Certificate of Designations and Series F-1 Certificate of Designations), pursuant to which, the Required Holders agreed to amend (i) the Series F-1 Certificate of Designations, as described below, by filing a Certificate of Amendment to the Series F-1 Certificate of Designations with the Secretary of State (the “August 2025 Series F-1 Certificate of Amendment”), (ii) the Series F Certificate of Designations, as described below, by filing a Certificate of Amendment to the Series F Certificate of Designations with the Secretary of State (the “August 2025 Series F Certificate of Amendment”), and (iii) to amend the term of the Series F Warrants and Series F-1 Warrants such that such warrants have a term expiring on August 15, 2030. In addition, in consideration of the foregoing, the Required Holder is entitled to nominate one director to the board of directors, provided that such nomination shall be approved by the Company’s Nominating and Governance Committee, which approval shall not be unreasonably withheld.

The August 2025 Series F Certificate of Amendment amends the Series F Certificate of Designations to (A) (i) extend the maturity date to December 31, 2025, and (ii) modify the schedule of Installment Dates (as defined in the Series F Certificate of Designations), in each case, effective as of June 30, 2025.

On September 2, 2025, the Company entered into an Omnibus Amendment Agreement (the “September 2025 Omnibus Amendment”) with the Required Holders (as defined in each of (i) the Series F Certificate of Designations and (ii) the Series F-1 Certificate of Designations) pursuant to which, the Required Holders agreed to (i) amend and restate the Series F Certificate of Designations by filing a Second Amended and Restated Certificate of Designations of the Series F Preferred Stock (the “Second Amended and Restated Series F Certificate of Designations”) with the Secretary of State, and (ii) amend and restate the Series F-1 Certificate of Designations by filing an Amended and Restated Certificate of Designations of the Series F-1 Preferred Stock (the “Amended and Restated Series F-1 Certificate of Designations”) with the Secretary of State. Each of the Second Amended and Restated Series F Certificate of Designations and the Amended and Restated Series F-1 Certificate of Designations (i) extend the maturity date of each of Series F Convertible Preferred Stock and Series F-1 Convertible Preferred Stock to March 2, 2027, and (ii) remove the amortization payments and related terms and covenants.

The Series F Preferred Shares are classified in temporary equity as the holder of the Series F Preferred Shares have the right to require the Company to redeem for cash all or any portion of each such holder’s shares upon the suspension from trading or the failure of the Common Stock to be trading or listed (as applicable) on an eligible trading market for a period of five (5) consecutive trading days. The Series F Preferred Shares are not unconditionally redeemable and are only conditionally puttable at the holder’s option upon this trading suspension or failure. This would not be considered to be within the Company’s control.

The Series F Preferred Shares were determined to be more akin to a debt-like host than an equity-like host. The Company identified the following embedded features that are not clearly and closely related to the debt host instrument: 1) make-whole interest upon a contingent redemption event, 2) make-whole interest upon a conversion event, 3) an installment redemption upon an Equity Conditions Failure (as defined in the Series F Certificate of Designations), and 4) variable share-settled installment conversion. These features were bundled together, assigned probabilities of being affected and measured at fair value. Subsequent changes in fair value of these features are recognized in the Consolidated Statements of Operations. The Company estimated at issuance the $3,149,800 fair value of the bifurcated embedded derivative using a Monte Carlo simulation model, with the following inputs; the fair value of the Company’s Common Stock of $190.00 on the issuance date, estimated equity volatility of 120.0%, estimated traded volume volatility of 190.0%, the time to maturity of 1.35 years, a discounted market interest rate of 6.8%, dividend rate of 10.0%, a penalty dividend rate of 15.0%, and probability of default of 0.5%. The fair value of the bifurcated derivative liabilities was estimated utilizing the with and without method which uses the probability weighted difference between the scenarios with the derivative and the plain vanilla maturity scenario without a derivative.

The discount to the fair value is included as a reduction to the carrying value of the Series F Preferred Shares. The Company recorded a total discount of $14,087,111 upon issuance of the Series F Preferred Shares, which was comprised of the issuance date fair value of the associated embedded derivative of $3,149,800, stock issuance costs of $314,311 and the fair value of the Series F Warrants of $10,623,000.

The Company performed an analysis of the change in fair value of the derivative liabilities pre and post the September 2, 2025 modification and determined the change in fair value to be immaterial. During the three months ended March 31, 2026 and 2025, the Company recorded gains of $0 and $0, respectively, related to the change in fair value of the derivative liabilities which is recorded in other income (expense) on the Condensed Consolidated Statements of Operations. The Series F Preferred Stock were fully converted during the three months ended September 30, 2025.  The derivative liability is reclassified to equity upon final conversion. Since the derivative had a fair value of $0 at time of conversion and there was no impact to equity.

The following are the principal terms of the Series F Preferred Shares:

Dividends

The holders of the Series F Preferred Shares are entitled to dividends of 10.0% per annum, compounded monthly, which are payable in cash or shares of Common Stock at the Company’s option, in accordance with the terms of the Series F Certificate of Designations. Upon the occurrence and during the continuance of a Triggering Event (as defined in the Series F Certificate of Designations), Series F Preferred Shares will accrue dividends at the rate of 15.0% per annum. Upon conversion or redemption, the holders of Series F Preferred Shares are also entitled to receive a dividend make-whole payment. During the three months ended March 31, 2026 and 2025, the Company recorded no dividends for Series F Preferred Shares.

Liquidation

Upon any liquidation, dissolution or winding-up of the Company, whether voluntary or involuntary, each holder of the Series F Preferred Shares shall be entitled to receive out of the assets, whether capital or surplus, of the Company an amount per share of Series F Preferred Shares equal to the greater of (A) 125% of the stated value of such share of Series F Preferred Shares (plus any applicable make-whole amount, unpaid late charge or other applicable amount) on the date of such payment and (B) the amount per share such holder would receive if such holder converted such share of Series F Preferred Shares into Common Stock immediately prior to the date of such payment. All shares of capital stock of the Company shall be junior in rank to all Series F Preferred Shares with respect to the preferences as to payments upon liquidation.

Series F-1 Preferred Stock

On May 20, 2024, the Company entered into a Securities Purchase Agreement (the “Series F-1 Purchase Agreement”) with certain accredited investors (the “Series F-1 Investors”) pursuant to which it agreed to sell to the Series F-1 Investors (i) an aggregate of 5,050 shares of the Company’s newly-designated Series F-1 Preferred Stock, initially convertible into up to 27,813 shares of Common Stock at a conversion price of $181.60 per share (the “Series F-1 Conversion Shares”), (ii) short-term warrants to acquire up to an aggregate of 27,813 shares of Common Stock (the “Series F-1 Short-Term Warrants”) at an exercise price of $181.60 per share, and (iii) long-term warrants to acquire up to an aggregate of 27,813 shares of Common Stock (the “Series F-1 Long-Term Warrants,” and collectively with the Series F-1 Short-Term Warrants, the “Series F-1 Warrants”) at an exercise price of $181.60 per share (collectively, the “Series F-1 Private Placement”). The closing of the Series F-1 Private Placement occurred on May 23, 2024 (the “Series F-1 Closing Date”). The Series F-1 Conversion Price is subject to customary adjustments for stock dividends, stock splits, reclassifications and the like, and subject to price-based adjustment in the event of any issuances of Common Stock, or securities convertible, exercisable or exchangeable for Common Stock, at a price below the then-applicable Series F-1 Conversion Price (subject to certain exceptions).

On April 17, 2025, in connection with the issuance of stock options to certain officers of the Company and pursuant to the full ratchet anti-dilution provisions contained in the Series F Certificate of Designations the Series F-1 Conversion Price was adjusted to $18.32 per share. In September 2025, in connection with the 2025 Reverse Stock Split, and pursuant to the stock combination event adjustment provisions contained in the Series F-1 Certificate of Designations, the Series F-1 Conversion Price was reduced to $3.3713 per share.

The Company initially was required to redeem the Series F-1 Preferred Stock in equal monthly installments, commencing on December 1, 2024. The amortization payments due upon such redemption are payable, at the Company’s election, in cash at 105% of the applicable Installment Redemption Amount (as defined in the Series F-1 Certificate of Designations), or subject to certain limitations, in shares of Common Stock valued at the lower of (i) the Series F-1 Conversion Price then in effect and (ii) the greater of (A) 80% of the average of the three lowest closing prices of the Company’s Common Stock during the thirty consecutive trading day period ending and including the trading day immediately prior to the date the amortization payment is due or (B) $0.364, which is 20% of the “Minimum Price” (as defined in Nasdaq Stock Market Rule 5635) on the date in which the approval of the Company’s stockholders in accordance with Nasdaq listing standards for the issuance of shares in connection with the Series F-1 Private Placement (the “Series F-1 Stockholder Approval”) was obtained or, in any case, such lower amount as permitted, from time to time, by the Nasdaq Capital Market, and, in each case, subject to adjustment for stock splits, stock dividends, stock combinations, recapitalizations or other similar events, which amortization amounts are subject to certain adjustments as set forth in the Series F-1 Certificate of Designations (the “Series F-1 Floor Price”).

In addition, in consideration of the foregoing, the Company agreed to reduce the size of the board of directors of the Company to no more than six directors, no later than the Company’s 2025 annual meeting of stockholders.

The April 2025 Series F-1 Certificate of Amendment amends the Series F-1 Certificate of Designations to amend the definition of “Excluded Securities” substantially similar to the Excluded Securities Modification.

The shares of Series F-1 Preferred Stock are classified as temporary equity as the holders of the Series F-1 Preferred Stock have the right to require the Company to redeem for cash all or any portion of each such holder’s shares upon the suspension from trading or the failure of the Common Stock to be trading or listed (as applicable) on an eligible trading market for a period of five (5) consecutive trading days. The Series F-1 Preferred Stock is not unconditionally redeemable and is only conditionally puttable at the holder’s option upon this trading suspension or failure. This would not be considered to be within the Company’s control.

The estimated fair value of the Series F-1 Preferred Stock on the issuance date of approximately $9.3 million, was determined utilizing Monte Carlo simulations. The estimated aggregate fair value of the Series F-1 Warrants of approximately $7.9 million was determined utilizing the Black Scholes Model. The aggregate fair value of the Series F-1 Warrants exceeds the aggregate gross proceeds from the transaction as the Series F-1 Warrants were issued below fair market value of the Company’s Common stock. Further, the fair value of the derivative liability related to the Series F-1 Preferred Stock was determined to be approximately $0.9 million on the date of issuance.

The approximately $5.1 million stock discount (contra-Preferred Stock) resulting from (i) approximately $4.2 million related to the difference between the gross proceeds and the allocated residual fair value of the Series F-1 Preferred Stock (i.e., $0), and (ii) approximately $0.9 million related to the stock derivative at issuance, is accounted for as a reduction to the carrying value of the Series F-1 Preferred Shares and will be accreted from the issuance date to maturity in accordance with ASC 480-10-S99-3A as redemption is deemed probable pursuant to the Installment Redemption terms of the Series F-1 Certificate of Designations.

The Company performed an analysis of the change in fair value of the derivative liabilities pre and post the September 2, 2025 modification and determined the change in fair value to be immaterial. During the three months ended March 31, 2026 and 2025, the Company recorded a gains of $0 and $0, respectively, related to the change in fair value of the derivative liabilities, which is recorded in other income (expense) on the Consolidated Statements of Operations. The Series F-1 Preferred Stock were fully converted during the three months ended March 31, 2026. The derivative liability is reclassified to equity upon final conversion. Since the derivative had a fair value of $0 at time of conversion and there was no impact to equity.

The following are the principal terms of the Series F-1 Preferred Stock:

Dividends

The holders of the Series F-1 Preferred Stock are entitled to dividends of 10% per annum, compounded monthly, which are payable in arrears monthly in cash or shares of Common Stock at the Company’s option, in accordance with the terms of the Series F-1 Certificate of Designations. Upon the occurrence and during the continuance of a Triggering Event (as defined in the Series F-1 Certificate of Designations), the Series F-1 Preferred Stock will accrue dividends at the rate of 15% per annum. Upon conversion or redemption, the holders of the Series F-1 Preferred Stock are also entitled to receive a dividend make-whole payment. During the three months ended March 31, 2026 and 2025, the Company recorded dividends totaling $0 and $0, respectively, which are reported as Preferred Stock Dividends on the Consolidated Statements of Operations.

Liquidation

Upon any liquidation, dissolution or winding-up of the Company, whether voluntary or involuntary, each holder of shares of the Series F-1 Preferred Stock shall be entitled to receive out of the assets, whether capital or surplus, of the Company an amount per share of Series F-1 Preferred Stock equal to the greater of (A) 125% of the stated value of such share of Series F-1 Preferred Stock (plus any applicable make-whole amount, unpaid late charge or other applicable amount) on the date of such payment and (B) the amount per share such holder would receive if such holder converted such share of Series F-1 Preferred Stock into Common Stock immediately prior to the date of such payment. All shares of capital stock of the Company shall be junior in rank to all shares of Series F-1 Preferred Stock with respect to the preferences as to payments upon liquidation.

Series G Preferred Stock

On May 20, 2024, the Company entered into a Securities Purchase Agreement (the “Series G Purchase Agreement” and collectively with the Series F-1 Purchase Agreement, each a “Purchase Agreement” and collectively, the “Purchase Agreements”) with certain accredited investors (the “Series G Investors” and collectively with the Series F-1 Investors, the “Investors”), pursuant to which it agreed to sell to the Series G Investors (i) an aggregate of 8,950 shares of the Company’s newly-designated Series G Preferred Stock, initially convertible into up to 49,288 shares of the Company’s Common Stock (the “Series G Conversion Shares”), at an initial conversion price of $181.60 per share (the “Series G Conversion Price”), (ii) short-term warrants to acquire up to an aggregate of 49,288 shares of Common Stock (the “Series G Short-Term Warrants”) at an exercise price of $181.60 per share, and (iii) long-term warrants to acquire up to an aggregate of 49,288 shares of Common Stock (the “Series G Long-Term Warrants,” and collectively with the Series G Short-Term Warrants, the “Series G Warrants”) at an exercise price of $181.60 per share (collectively, the “Series G Private Placement” and collectively with the Series F-1 Private Placement, each a “Private Placement” and collectively, the “Private Placements”). The closing of the Series G Private Placement occurred on May 23, 2024 (the “Series G Closing Date” and collectively with the Series F-1 Closing Date, the “Closing Date”). The Series G Conversion Price is subject to customary adjustments for stock dividends, stock splits, reclassifications and the like, and subject to price-based adjustment in the event of any issuances of Common Stock, or securities convertible, exercisable or exchangeable for Common Stock, at a price below the then-applicable Series G Conversion Price (subject to certain exceptions).

On April 17, 2025, in connection with the issuance of stock options to certain officers of the Company, (i) the Series G Conversion Price was equal to $18.32 per share due to the full ratchet anti-dilution provisions contained in the Series G Certificate of Designations. In August 2025, in connection with the 2025 Reverse Stock Split, and pursuant to the stock combination event adjustment provisions contained in the Series G Certificate of Designations, the Series G Conversion Price was reduced to $3.3713 per share.

At any time after the issuance date of the Series G Preferred Shares, the Company has the option to redeem in cash all or any portion of the shares of Series G Preferred Shares then outstanding at a premium upon notice by the Company to all holders of the Series G Preferred Shares.

The holders of the Series G Preferred Shares will be entitled to dividends of 10% per annum, compounded monthly, which will be payable in arrears monthly, at the holder’s option, (i) in cash, (ii) “in kind” in the form of additional shares of Series G Preferred Shares (the “PIK Shares”), or (iii) in a combination thereof, in each case, in accordance with the terms of the Certificate of Designations of the Series G Preferred Stock (the “Series G Certificate of Designations”). Upon the occurrence and during the continuance of a Triggering Event (as defined in the Series G Certificate of Designations), the Series G Preferred Stock will accrue dividends at the rate of 15% per annum. Upon conversion or redemption, the holders of the Series G Preferred Shares are also entitled to receive a dividend make-whole payment. The holders of the Series G Preferred Shares will be entitled to vote with holders of the Common Stock on an as-converted basis, with the number of votes to which each holder of Series G Preferred Share is entitled to be calculated assuming a conversion price of $2.253 per share, which was the Minimum Price (as defined in Rule 5635 of the Rules of the Nasdaq Stock Market) applicable immediately before the execution and delivery of the Series G Purchase Agreement, subject to certain beneficial ownership limitations as set forth in the Series G Certificate of Designations. During the three months ended March 31, 2026 and 2025, the Company recorded dividends totaling $229,671 and $0, respectively, which are reported as Preferred Stock Dividends on the Consolidated Statements of Operations.

Notwithstanding the foregoing, the Company’s ability to settle conversions and make dividend make-whole payments using shares of Common Stock is subject to certain limitations set forth in the Series G Certificate of Designations. Further, the Series G Certificate of Designations contains a certain beneficial ownership limitation, which applies to each Series G Investor, other than PharmaCyte Biotech, Inc., after giving effect to the issuance of shares of Common Stock issuable upon conversion of the Series G Preferred Shares or as part of any dividend make-whole payment under the Series G Certificate of Designations.

Upon any liquidation, dissolution or winding-up of the Company, whether voluntary or involuntary, each holder of shares of the Series G Preferred Stock shall be entitled to receive out of the assets, whether capital or surplus, of the Company an amount per share of Series G Preferred Stock equal to the greater of (A) 125% of the stated value of such share of Series G Preferred Stock (plus any applicable make-whole amount, unpaid late charge or other applicable amount) on the date of such payment and (B) the amount per share such holder would receive if such holder converted such share of Series G Preferred Stock into Common Stock immediately prior to the date of such payment. All shares of capital stock of the Company shall be junior in rank to all shares of Series G Preferred Stock with respect to the preferences as to payments upon liquidation.

On June 17, 2024, the Company entered into an Amendment Agreement (the “Series G Amendment”) with the Required Holders (as defined in the Series G Certificate of Designations). Pursuant to the Series G Amendment, the Required Holders agreed to amend the Series G Certificate of Designations by filing a Certificate of Amendment (“Series G Certificate of Amendment”) to the Series G Certificate of Designations with the Secretary of State of the State of Delaware (the “Secretary of State”) to increase the number of authorized shares of Series G Preferred Stock from 8,950 to 12,826,273, in order to authorize a sufficient number of shares of Series G Preferred Stock for the payment of PIK Shares. On June 17, 2024, the Company filed the Series G Certificate of Amendment with the Secretary of State, thereby amending the Series G Certificate of Designations. The Series G Certificate of Amendment became effective with the Secretary of State upon filing.

The shares of Series G Preferred Stock are classified as temporary equity as the holders of the Series G Preferred Stock have the right to require the Company to redeem for cash all or any portion of each such holder’s shares upon the suspension from trading or the failure of the Common Stock to be trading or listed (as applicable) on an eligible trading market for a period of five (5) consecutive trading days. The Series G Preferred Stock is not unconditionally redeemable and is only conditionally puttable at the holder’s option upon this trading suspension or failure. This would not be considered to be within the Company’s control.

The estimated fair value of the Series G Preferred Stock on the issuance date of approximately $22.3 million, was determined utilizing Monte Carlo simulations. The estimated aggregate fair value of the Series G Warrants of approximately $14.1 million was determined utilizing the Black Scholes Model. The aggregate fair value of the Series G Warrants exceeds the aggregate gross proceeds from the transaction as the Series G Warrants were issued below fair market value of the Company’s Common stock.

The approximately $9.0 million stock discount (contra-Preferred Stock) resulting from the difference between the gross proceeds and the allocated residual fair value of the Series G Preferred Stock (i.e. $0) is accounted for as a reduction to the carrying value of the Series G Preferred Stock and is not accreted until redemption becomes probable in accordance with ASC 480-10-S99-3A.

Since the fair value of the liabilities required to be subsequently measured at fair value exceeds the net proceeds received, the excess of the fair value over the net proceeds received is recognized as a loss in earnings. As such, the Company recognized a loss on the issuance of preferred stock of approximately $5.1 million.

On August 8, 2024, the Company entered into an Amendment Agreement (the “August Series G Amendment”) with the Required Holders (as defined in the Series G Certificate of Designations). Pursuant to the August Series G Amendment, the Required Holders agreed to amend the Series G Certificate of Designations by filing a Certificate of Amendment (“August Series G Certificate of Amendment”) to the Series G Certificate of Designations with the Secretary of State to adjust the calculation of the PIK Shares. On August 8, 2024, the Company filed the August Series G Certificate of Amendment with the Secretary of State, thereby amending the Series G Certificate of Designations. The August Series G Certificate of Amendment became effective with the Secretary of State upon filing.

During the three months ended March 31, 2026 and March 31, 2025, the Company did not issue Series G Preferred Stock in lieu of dividends.

Series H Preferred Stock

On September 2, 2025, the Company entered into a Securities Purchase Agreement (the “Series H Purchase Agreement”) with certain accredited investors (the “Series H Investors”), pursuant to which it issued and sold on September 4, 2025 (the “Series H Closing Date”) in a private placement (i) an aggregate of 7,000 shares of the Company’s newly-designated Series H Preferred Stock, initially convertible into up to 1,400,000 shares of Common Stock (the “Series H Conversion Shares”) at an initial conversion price of $5.00 per share (the “Series H Conversion Price”), and (ii) warrants to acquire up to an aggregate of 1,400,000 shares of Common Stock at an initial exercise price of $5.00 per share (the “Series H Investor Warrants”) (collectively, the “Series H Private Placement”). The aggregate gross proceeds from the Private Placement were $7,000,000.

The Series H Conversion Price is subject to customary adjustments for stock dividends, stock splits, reclassifications, stock combinations and the like, and subject to price-based adjustment in the event of any issuances of Common Stock, or securities convertible, exercisable or exchangeable for Common Stock, at a price below the then-applicable Series H Conversion Price (subject to certain exceptions).. The Series H Conversion Price may also be voluntarily reduced by the Company to any amount and for any period of time deemed appropriate by the Board at any time with the prior written consent of the holders of at least a majority of the outstanding shares of Series H Preferred Stock, subject to the rules and regulations of Nasdaq.

The holders of the Series H Preferred Stock are entitled to dividends of 7% per annum, compounded each calendar quarter, which are payable in arrears (i) on the first trading day of each quarter, commencing on October 1, 2025 and (ii) upon any redemption or any required payment upon any Triggering Event (as defined in the Certificate of Designations of the Series H Convertible Preferred Stock (the “Series H Certificate of Designations”)). The holders of the Series H Preferred Stock are also entitled to receive a dividend make-whole payment. Upon the occurrence and during the continuance of a Triggering Event, the Series H Preferred Stock will accrue dividends at the rate of 15% per annum. The holders of the Series H Preferred Stock will be entitled to vote with holders of the Common Stock on an as-converted basis, with the number of votes to which each holder of Series H Preferred Stock is entitled to be calculated assuming a conversion price of $4.83 per share, which was the Minimum Price (as defined in Rule 5635 of the Rule of the Nasdaq Stock Market) applicable immediately before the execution and delivery of the Series H Purchase Agreement, subject to certain beneficial ownership limitations as set forth in the Series H Certificate of Designations. During the three months ended March 31, 2026 and 2025, the Company recorded dividends totaling $55,999 and $0, respectively, which are reported as Preferred Stock Dividends on the Consolidated Statements of Operations.

Notwithstanding the foregoing, the Company’s ability to issue any shares of Common Stock upon conversion of any shares of Series H Preferred Stock or otherwise pursuant to the terms of the Series H Certificate of Designations is subject to certain limitations set forth in the Series H Certificate of Designations, including a limit on the number of shares that may be issued until the time, if any, that the Company’s stockholders have approved the issuance of the Series H Conversion Shares and shares issuable upon exercise of the Series H Investor Warrants (the “Series H Stockholder Approval”). The Series H Stockholder Approval was obtained on November 14, 2025 at a special meeting of stockholders of the Company. Further, except with respect to Pharmacyte, the Series H Certificate of Designations contains a certain beneficial ownership limitation after giving effect to the issuance of shares of Common Stock issuable upon conversion of the Series H Preferred Stock.

The shares of Series H Preferred Stock were determined to be more akin to a debt-like host than an equity-like host. The Company identified the following embedded features that are not clearly and closely related to the debt host instrument: 1) certain contingent redemption options, 2) optional conversion features inclusive of make-whole interest and 3) an increase in the dividend rate related to the occurrence of a triggering event. These features were bundled together, assigned probabilities of being affected and measured at fair value. Subsequent changes in fair value of these features are recognized in the Consolidated Statement of Operations. The Company estimated the $1,837,000 fair value of the bifurcated embedded derivative at issuance using a discounted cash flow scenario model, with the following inputs: the fair value of our common stock of $3.61 on the issuance date, estimated equity volatility of 100.0%, the time to maturity of 1.49 years, the redemption premium of 106%, a market interest rate of 19.51%, a risk-free rate of 3.61%, and dividend rate of 7%. The fair value of the bifurcated derivative liability was estimated utilizing the with and without method which uses the probability weighted difference between the scenarios with the derivative and the plain vanilla maturity scenario without a derivative.

The discount to the fair value is included as a reduction to the carrying value of the Series H Preferred Stock. On September 30, 2025, the Company recorded a total discount of $4,472,000 upon issuance of the Series H Preferred Stock, which was comprised of the issuance date fair value of the associated embedded derivative of $1,837,000, stock issuance costs of $425,063, and amount allocated to the Series H Warrants of $2,209,937.

In connection with the Series H Private Placement, the Company and the Series H Investors entered into that certain Registration Rights Agreement, dated as of September 2, 2025 (the “Series H Registration Rights Agreement,” and, together with the Series H Purchase Agreement, the Series H Certificate of Designations, and the Series H Investor Warrants, the “Transaction Documents”), pursuant to which, the Company agreed to, among other things, prepare and file with the SEC a registration statement (the “Series H Registration Statement”) covering the resale of all of the Registrable Securities (as defined in the Series H Registration Rights Agreement) prior to the applicable Filing Deadline (as defined in the Series H Registration Rights Agreement).

On September 30, 2025, the Company entered into an Omnibus Waiver and Amendment (the “September 2025 Amendment”) with the Required Holders (as defined in the Series H Certificate of Designations). Pursuant to the Amendment, the Required Holders agreed (A) to amend (i) the Series H Certificate of Designations, as described below, by filing a Certificate of Amendment (“September 2025 Certificate of Amendment”) to the Series H Certificate of Designations with the Secretary of State, (ii) the Series H Purchase Agreement to amend the definition of “Excluded Securities” such that the definition includes the issuance of Common Stock issued after the date of the Series H Purchase Agreement pursuant to an Approved Stock Plan (as defined in the Series H Purchase Agreement) which in the aggregate does not exceed more than 15.0% of the sum of (x) shares of Common Stock issued and outstanding as of the date of the Series H Purchase Agreement, and (y) the shares of Common Stock issuable upon conversion of certain of the Company’s outstanding shares of preferred stock (the “Excluded Securities Modification”), and (iii) the Series H Registration Rights Agreement such that the Series H Registration Statement is required to be filed with the SEC by the date that is 30 calendar days following the Series H Closing Date and (B) waive (i) any prohibitions or limitations under the Transaction Documents in connection with the issuance by the Company of certain warrants to purchase Common Stock to certain current and future consultants of the Company, (ii) any prohibitions or limitations under the Transaction Documents in connection with the registration of certain securities of the Company, and (iii) any failure by the Company to file the Series H Registration Statement by the Filing Deadline.

The September 2025 Certificate of Amendment amends the Series H Certificate of Designations to amend the definition of “Excluded Securities” substantially similar to the Excluded Securities Modification. On October 3, 2025, the Company filed the September 2025 Certificate of Amendment with the Secretary of State, thereby amending the Series H Certificate of Designations. The September 2025 Certificate of Amendment became effective with the Secretary of State upon filing.

Series I Preferred Stock

On September 2, 2025, the Company entered into that certain Membership Interest Purchase Agreement (the “MIPA”), by and among the Company, LPU Holdings LLC (“LPU”) and the members of LPU (the “Sellers”), pursuant to which the Company agreed to acquire 100% of the membership interests (the “Membership Interests”) of LPU from the Sellers (the “Acquisition”). As consideration for the Membership Interests, the Company delivered to the Sellers that number of shares of Series I Preferred Stock that is convertible into a number of shares of Common Stock equal to 747,362, subject to certain conversion limitations as described in the Certificate of Designations for the Series I Convertible Preferred Stock (“Series I Certificate of Designations”), which was filed and became effective with the Secretary of State on September 3, 2025.

The shares of Series I Preferred Stock are convertible into shares of Common Stock at the election of the holder at any time at an initial conversion price of $0.01 (the “Series I Conversion Price”), provided that, until the receipt of requisite stockholder approval of the Company for the issuance of all Series I Conversion Shares in excess of 19.99% of the issued and outstanding shares of Common Stock of the Company (the “MIPA Stockholder Approval”), the Company may not issue a number of Series I Conversion Shares which, when aggregated with any shares of Common Stock issued on or after the closing date and prior to the applicable conversion date in connection with any conversion of shares of Series I Preferred Stock issued pursuant to the MIPA, would exceed 357,052 shares of Common Stock (subject to adjustment for forward and reverse stock splits, recapitalizations and the like). The MIPA Stockholder Approval was obtained on November 14, 2025, at a special meeting of stockholders of the Company. The Series I Conversion Price is subject to customary adjustments for stock dividends, stock splits, reclassifications and the like.

The number of Series I Conversion Shares initially may not exceed 456,536 (the “Maximum Issuance”); provided, however, that (A) upon the issuance of Common Stock in connection with any conversions of the Series F Preferred Stock pursuant to the terms of Series F Certificate of Designations, the Series F-1 Preferred Stock pursuant to the terms of the Series F-1 Certificate of Designations, the shares of Series I Preferred Stock pursuant to the terms of the Series I Certificate of Designations (collectively, the “Existing Preferred Stock”), and (B) upon the issuance of Common Stock in connection with any exercise, conversion or issuance of any securities exchanged for Existing Preferred Stock after the date of issuance of the Series I Preferred Stock (“Exchanged Securities”), the Maximum Issuance shall be increased to equal the sum of (i) the Maximum Issuance immediately prior to the date of such conversion plus (ii) 0.1999 shares of Common Stock for each share of Common Stock issued upon conversion, exercise or issuance of the applicable Existing Preferred Stock or Exchanged Securities.

Holders of Series I Preferred Stock are entitled to receive, and the Company shall pay, dividends as and when paid to the holders of Common Stock of the Company on an as-converted basis, ignoring for such purposes any limitations on conversion hereunder. Subject to applicable beneficial ownership limitations, on any matter presented to the stockholders of the Company for their action or consideration at any meeting of stockholders of the Company (or by written consent of stockholders in lieu of a meeting), each holder of Series I Preferred Stock, in its capacity as such, shall be entitled to cast the number of votes equal to the number of whole shares of Common Stock into which the Series I Preferred Stock beneficially owned by such holder are convertible as of the record date for determining stockholders entitled to vote on or consent to such matter (taking into account all Series I Preferred Stock beneficially owned by such holder).

The Series I Preferred Stock was determined to be more akin to an equity-like host than a debt-like host. There were no embedded derivative features identified requiring bifurcation. The Series I Preferred Stock is classified in mezzanine equity pursuant to ASC 480-10-S99 as it may be settled for cash upon an event outside of the Company’s control.

The Series I Preferred Stock was issued as consideration in connection with an asset acquisition (see Note 9) and was thus recognized at its issuance date fair value of $2,697,977. The Series I Preferred Stock was fully converted in 2025 and no shares remain outstanding as of March 31, 2026.

Common Stock

The holders of Common Stock are entitled to one vote per share at meetings of stockholders of the Company.

As of March 31, 2026, the Company had 7,853,429 shares of Common Stock issued and outstanding.

During the three months ended March 31, 2026, the Company issued 155,432 shares of Common Stock, for the exercise of Series H Preferred Stock Warrants and 7,594 shares of Common Stock for the conversion of vested Restricted Stock Units.

Common Stock Warrants

The table below summarizes the warrant activity for the three months ended March 31, 2026:

 Summary of Warrant Activity

The aggregate intrinsic value is calculated as the difference between the exercise price of the underlying awards and the closing stock price of $3.45 for the Company’s Common Stock on March 31, 2026 and the closing stock price of $0.35 for the Company’s Common Stock on December 31, 2025. All warrants were vested on date of grant.

On April 17, 2025, in connection with the issuance of Stock Options, (i) the Series F Conversion Price, Series F-1 Conversion Price and Series G Conversion Price was adjusted to $18.32 per share pursuant to the full ratchet anti-dilution provisions contained in the applicable Certificate of Designations and, (ii) the Series F Exercise Price, the Series F-1 Exercise Price and Series G Exercise Price was adjusted to $18.32 per share and the number of shares of Common Stock issuable upon exercise of such warrants was adjusted proportionally pursuant to the full ratchet anti-dilution provisions contained in the applicable warrants.

Series F Common Stock Warrants

Pursuant to the February 2023 Offering, the Company issued to investors the Series F Warrants to purchase 66,523 shares of Common Stock, with an initial exercise price of $6,865.00 per share, which, as of March 31, 2026, was adjusted to $3.3713 per share and the number of shares of Common Stock issuable upon exercise of the Series F Warrants was adjusted proportionally to 4,449,325 shares pursuant to the full ratchet anti-dilution provisions contained in the Series F Warrants in connection with the issuance of shares of Common Stock upon conversion of the Series F-1 Preferred Shares (the “Series F Exercise Price”), for a period of five years from the date of issuance. The Series F Exercise Price and the number of shares issuable upon exercise of the Series F Warrants are subject to customary adjustments for stock dividends, stock splits, reclassifications and the like, and subject to price-based adjustment, on a “full ratchet” basis, in the event of any issuances of Common Stock, or securities convertible, exercisable or exchangeable for Common Stock, at a price below the then-applicable Exercise Price (subject to certain exceptions). Upon any such price-based adjustment to the exercise price, the number of shares issuable upon exercise of the Series F Warrants will be increased proportionately.

Following the 2024 Reverse Stock Split, the exercise price of the Series F Warrants was reduced to $318.00 per share pursuant to the stock combination event adjustment provisions contained in the Series F Warrants and the number of shares of Common Stock issuable upon exercise of the Series F Warrants was adjusted proportionately. In May 2024, in connection with the Private Placements, the exercise price of the Series F Warrants was reduced to $181.60 per share pursuant to the full ratchet anti-dilution provisions contained in the Series F Warrants and the number of shares of Common Stock issuable upon exercise of the Series F Warrants was adjusted proportionately. On April 17, 2025, in connection with the issuance of stock options to certain officers of the Company and pursuant to the full ratchet anti-dilution provisions contained in the Series F Warrants, the exercise price of the Series F Warrants was reduced to $18.32 per share and the number of shares of Common Stock issuable upon exercise of the Series F Warrants was adjusted proportionately. In September 2025, in connection with the 2025 Reverse Stock Split and pursuant to the stock combination event adjustment provisions contained in the Series F Warrants, the exercise price of the Series F Warrants was reduced to $3.3713 per share and the number of shares of Common Stock issuable upon exercise of the Series F Warrants was adjusted proportionately.

The Series F Warrants were initially accounted for as liabilities based on the following analysis:

The Series F Warrants were determined to be within the scope of ASC 480-10 as they are puttable to the Company at the Holders’ election upon the occurrence of a Fundamental Transaction (as defined in the agreements). As such, the Company recorded the Series F Warrants as a liability at fair value with subsequent changes in fair value recognized in earnings. The Company utilized the Black Scholes Model to calculate the value of these warrants. The fair value of the Series F Warrants of $10,623,000 was estimated at the date of issuance using the following weighted average assumptions: dividend yield 0%; term of 5.0 years; equity volatility of 125.0%; and a risk-free interest rate of 4.09%.

Transaction costs incurred attributable to the issuance of the Series F Warrants of $762,834 were immediately expensed in accordance with ASC 480.

Series F-1 Warrants

Pursuant to the Series F-1 Private Placement, the Company issued to investors (i) the Series F-1 Long-Term Warrants to purchase 27,813 shares of Common Stock, with an initial exercise price of $181.60 per share (subject to adjustment), for a period of five years from the date of issuance and (ii) the Series F-1 Short-Term Warrants to purchase 27,813 shares of Common Stock, with an initial exercise price of $181.60 per share (subject to adjustment), for a period of eighteen months from the date of issuance. The exercise price of the Series F-1 Warrants and the number of shares issuable upon exercise of the Series F-1 Warrants are subject to customary adjustments for stock dividends, stock splits, reclassifications and the like, and subject to price-based adjustment, on a “full ratchet” basis, in the event of any issuances of Common Stock, or securities convertible, exercisable or exchangeable for Common Stock, at a price below the then-applicable exercise price (subject to certain exceptions). Upon any such price-based adjustment to the exercise price, the number of shares issuable upon exercise of the Series F-1 Warrants will be increased proportionately.

On April 17, 2025, in connection with the issuance of stock options to certain officers of the Company and pursuant to the full ratchet anti-dilution provisions contained in the Series F-1 Warrants, the exercise price of the Series F-1 Warrants was reduced to $18.32 per share and the number of shares of Common Stock issuable upon exercise of the Series F-1 Warrants was adjusted proportionately. In September 2025, in connection with the 2025 Reverse Stock Split and pursuant to the stock combination event adjustment provisions contained in the Series F-1 Warrants, the exercise price of the Series F-1 Warrants was reduced to $3.3713 per share and the number of shares of Common Stock issuable upon exercise of the Series F-1 Warrants was adjusted proportionately.

Pursuant to the April 2025 Amendment Agreement, the Series F-1 Short-Term Warrants were extended to expire five years from the date of issuance.

The Series F-1 Preferred Shares were determined to be more akin to a debt-like host than an equity-like host. The Company identified the following embedded features that are not clearly and closely related to the debt host instrument: 1) make-whole interest upon a contingent redemption event, 2) make-whole interest upon a conversion event, 3) an installment redemption upon an Equity Conditions Failure (as defined in the Series F-1 Certificate of Designations), and 4) variable share-settled installment conversion. These features were bundled together, assigned probabilities of being affected and measured at fair value. Subsequent changes in fair value of these features are recognized in the Consolidated Statements of Operations. The Company estimated at issuance the $3,149,800 fair value of the bifurcated embedded derivative using a Monte Carlo simulation model, with the following inputs: the fair value of the Company’s Common Stock of $190.00 on the issuance date, estimated equity volatility of 120.0%, estimated traded volume volatility of 190.0%, the time to maturity of 1.35 years, a discounted market interest rate of 6.8%, dividend rate of 10.0%, a penalty dividend rate of 15.0%, and probability of default of 0.5%. The fair value of the bifurcated derivative liabilities was estimated utilizing the with and without method which uses the probability weighted difference between the scenarios with the derivative and the plain vanilla maturity scenario without a derivative.

Series G Warrants

Pursuant to the Series G Private Placement, the Company issued to investors (i) the Series G Long-Term Warrants to purchase 49,288 shares of Common Stock, with an initial exercise price of $181.60 per share (subject to adjustment), for a period of five years from the date of issuance and (ii) the Series G Short-Term Warrants to purchase 49,288 shares of Common Stock, with an initial exercise price of $181.60 per share (subject to adjustment), for a period of eighteen months from the date of issuance.

The exercise price of the Series G Warrants and the number of shares issuable upon exercise of the Series G Warrants are subject to customary adjustments for stock dividends, stock splits, reclassifications and the like, and subject to price-based adjustment, on a “full ratchet” basis, in the event of any issuances of Common Stock, or securities convertible, exercisable or exchangeable for Common Stock, at a price below the then-applicable exercise price (subject to certain exceptions). Upon any such price-based adjustment to the exercise price, the number of shares issuable upon exercise of the Series G Warrants will be increased proportionately.

On April 17, 2025, in connection with the issuance of stock options to certain officers of the Company and pursuant to the full ratchet anti-dilution provisions contained in the Series G Warrants, the exercise price of the Series G Warrants was reduced to $18.32 per share and the number of shares of Common Stock issuable upon exercise of the Series G Warrants was adjusted proportionately. In September 2025, in connection with the 2025 Reverse Stock Split and pursuant to the stock combination event adjustment provisions contained in the Series G Warrants, the exercise price of the Series G Warrants was reduced to $3.3713 per share and the number of shares of Common Stock issuable upon exercise of the Series G Warrants was adjusted proportionately.

The Series G Preferred Shares were determined to be more akin to a debt-like host than an equity-like host. The Company identified the following embedded features that are not clearly and closely related to the debt host instrument: 1) make-whole interest upon a contingent redemption event, 2) make-whole interest upon a conversion event, 3) an installment redemption upon an Equity Conditions Failure (as defined in the Series G Certificate of Designations), and 4) variable share-settled installment conversion. These features were bundled together, assigned probabilities of being affected and measured at fair value. Subsequent changes in fair value of these features are recognized in the Consolidated Statements of Operations. The Company estimated at issuance the $3,149,800 fair value of the bifurcated embedded derivative using a Monte Carlo simulation model, with the following inputs: the fair value of the Company’s Common Stock of $190.00 on the issuance date, estimated equity volatility of 120.0%, estimated traded volume volatility of 190.0%, the time to maturity of 1.35 years, a discounted market interest rate of 6.8%, dividend rate of 10.0%, a penalty dividend rate of 15.0%, and probability of default of 0.5%. The fair value of the bifurcated derivative liabilities was estimated utilizing the with and without method which uses the probability weighted difference between the scenarios with the derivative and the plain vanilla maturity scenario without a derivative.

During the three months ended March 31, 2026 and 2025, there were no exercises of Series G Short-Term Warrants.

Series H Warrants

Pursuant to the Series H Private Placement, the Company issued investors the Series H Investor Warrants to purchase 1,400,000 shares of Common Stock, with an initial exercise price of $5.00 per share (subject to adjustment), for a period of five years from the date of the Series H Stockholder Approval. The exercise price of the Series H Investor Warrants and the number of shares issuable upon exercise of the Series H Investor Warrants are subject to customary adjustments for stock dividends, stock splits, reclassifications and the like, and subject to price-based adjustment, on a “full ratchet” basis, in the event of any issuances of Common Stock, or securities convertible, exercisable or exchangeable for Common Stock, at a price below the then-applicable exercise price (subject to certain exceptions). Upon any such price-based adjustment to the exercise price, the number of shares issuable upon exercise of the Series H Investor Warrants will be increased proportionately. In September 2025, in connection with the 2025 Reverse Stock Split and pursuant to the full ratchet anti-dilution provisions contained in the Series H Investor Warrants, the exercise price of the Series H Investor Warrants was reduced to $3.3717 per share and the number of shares of Common Stock issuable upon exercise of the Series H Investor Warrants was adjusted proportionately.
