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.

Exchange Listing

Series D Preferred Stock is not listed on the Nasdaq, any national securities exchange or other nationally recognized trading system. The Company’s Common Stock issuable upon conversion of the Series D Preferred Stock is listed on the Nasdaq under the symbol “TNFA”.

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

As of June 30, 2025 and December 31, 2024, the Company had 72,992 shares of Series D Convertible Preferred Stock outstanding which represent 1,217 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 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 6,651,885 shares (pre-split) of the Company’s Common Stock at an initial conversion price of $2.255 per share (the “Series F Conversion Price”), subject to adjustment, and (ii) warrants to acquire up to an aggregate of 6,651,885 shares (pre-split) 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 $2.255. 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).

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 and Series F Warrants, (i) the Series F Conversion Price was adjusted to $0.1832 per share and, (ii) the Series F Exercise Price was equal to $0.1832 per share and the number of shares of Common Stock issuable upon exercise of the Series F Warrants was adjusted proportionally.

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 Series F Common Stock during the thirty trading day period immediately prior to the date the amortization payment is due or (B) a “Floor Price” of $6.60 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 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.

The April 2025 Series F Certificate of Amendment was filed with the Secretary of State of the State of Delaware, effective as of April 8, 2025.

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 of the State of Delaware (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 of the State of Delaware (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.

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 Comprehensive Loss. 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 $1.90 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.

During the three months ended June 30, 2025 and 2024, 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 Comprehensive Loss. During the six months ended June 30, 2025 and 2024, 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 Comprehensive Loss. The Company estimated the $0 fair value of the bifurcated embedded derivative at June 30, 2025 using a Monte Carlo simulation model, with the following inputs; the fair value of the Company’s Common Stock of $5,112,000 on the valuation date, estimated equity volatility of 125.0%, estimated traded volume volatility of 345.0%, the time to maturity of 0.50 years, a discounted market interest rate of 5.40%, dividend rate of 10.0%, a penalty dividend rate of 15.0%, and probability of default of 4.40%.

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 ended June 30, 2025 and 2024, the Company recorded dividends totaling $309,437 and $625,382, respectively, which are reported as Preferred Stock Dividends on the Consolidated Statements of Comprehensive Loss. During the six months ended June 30, 2025 and 2024, the Company recorded dividends totaling $920,723 and $1,827,249, respectively, which are reported as Preferred Stock Dividends on the Consolidated Statements of Comprehensive Loss.

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 2,780,839 shares of Common Stock at a conversion price of $1.816 per share (the “Series F-1 Conversion Shares”), (ii) short-term warrants to acquire up to an aggregate of 2,780,839 shares of Common Stock (the “Series F-1 Short-Term Warrants”) at an exercise price of $1.816 per share, and (iii) long-term warrants to acquire up to an aggregate of 2,780,839 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 $1.816 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 and Series F Warrants, (i) the Series F Conversion Price was adjusted to $0.1832 per share and, (ii) the Series F Exercise Price was equal to $0.1832 per share and the number of shares of Common Stock issuable upon exercise of the Series F Warrants was adjusted proportionally.

The Company initially is required to redeem the Series F-1 Preferred Stock in equal monthly installments, commencing on December 1, 2024.

On April 8, 2025, the Company entered into the April 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 the April 2025 Series F-1 Certificate of Amendment with the Secretary of State of the State of Delaware, (ii) the Series F Certificate of Designations, as described below, by filing the April 2025 Series F Certificate of Amendment, (iii) the Series F-1 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 Seres F-1 Purchase Agreement pursuant to an Approved Stock Plan (as defined in the Series F-1 Purchase Agreement), which in the aggregate does not exceed more than 2% of the shares of common stock issued and outstanding as of the date of such issuance, and (iv) to amend the term of the Series F-1 Short-Term Warrants to be five years from the date of issuance.

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 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.

During the three months ended June 30, 2025 and 2024, the Company recorded a gain of $19,000 and a loss of $72,000, respectively, related to the change in fair value of the derivative liabilities, which is recorded in other income (expense) on the Consolidated Statements of Comprehensive Loss. During the six months ended June 30, 2025 and 2024, the Company recorded a gain of $1,303,000 and a loss of $11,000, respectively, related to the change in fair value of the derivative liabilities, which is recorded in other income (expense) on the Consolidated Statements of Comprehensive Loss. The Company estimated the $2,180,000 fair value of the bifurcated embedded derivative at June 30, 2025, using a Monte Carlo simulation model, with the following inputs: the fair value of the Company’s Common Stock of $0.12 on the valuation date, estimated equity volatility of 125.0%, estimated traded volume volatility of 345.0%, the time to maturity of 0.50 years, a discounted market interest rate of 4.287%, dividend rate of 10.0%, a penalty dividend rate of 15.0%, and probability of default of 4.40%.

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 June 30, 2025 and 2024, the Company recorded dividends totaling $212,339 and $54,813, respectively, which are reported as Preferred Stock Dividends on the Consolidated Statements of Comprehensive Loss. During the six months ended June 30, 2025 and 2024, the Company recorded dividends totaling $407,807 and $54,813, respectively, which are reported as Preferred Stock Dividends on the Consolidated Statements of Comprehensive Loss.

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”), with certain accredited investors (the “Series G 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 4,928,416 shares of the Company’s Common Stock, at a conversion price of $1.816 per share (ii) short-term warrants to acquire up to an aggregate of 4,928,416 shares of Common Stock (the “Series G Short-Term Warrants”) at an exercise price of $1.816 per share, and (iii) long-term warrants to acquire up to an aggregate of 4,928,416 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 $1.816 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 $0.1832 per share due to the full ratchet anti-dilution provisions contained in the Series G Certificate of Designations and, (ii) the exercise price of the Series G Warrants was equal to $0.1832 per share and the number of shares of Common Stock issuable upon exercise of the Series G Short Term Warrants was equal to 48,853,711 shares and the number of shares of Common Stock issuable upon exercise of the Series G Long Warrants was equal to 48,853,711 shares, in each case, pursuant to the full ratchet anti-dilution provisions contained in the Series G Warrants.

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 options, (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 Shares (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 as 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 Rule 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 June 30, 2025 and 2024, the Company recorded dividends totaling $228,626 and $97,145, respectively, which are reported as Preferred Stock Dividends on the Consolidated Statements of Comprehensive Loss. During the six months ended June 30, 2025 and 2024, the Company recorded dividends totaling $461,336 and $97,145, respectively, which are reported as Preferred Stock Dividends on the Consolidated Statements of Comprehensive Loss.

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.

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 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.

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

Liquidation

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.

Common Stock

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

As of June 30, 2025, the Company had 29,383,743 shares of Common Stock issued and outstanding.

During the three and six months ended June 30, 2025, the Company issued and 4,068,388 and 4,313,388 shares of Common Stock, respectively, for conversions of Series G Preferred Stock.

Common Stock Warrants

The table below summarizes the warrant activity for the six months ended June 30, 2025:

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 $0.123 for the Company’s Common Stock on June 30, 2025 and the closing stock price of $1.15 for the Company’s Common Stock on December 31, 2024. 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 $0.1832 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 Conversion Price and Series G Exercise Price was adjusted to $0.1832 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 4,716,904 shares of Common Stock, with an initial exercise price of $3.18 per share, which, as of June 30, 2025, was adjusted to $0.1832 per share and the number of shares of Common Stock issuable upon exercise of the Series F warrants was adjusted proportionally to 81,877,728 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.

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 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.

During the three months ended March 31, 2024, the Company recorded a loss of $7,094,000 related to the change in fair value of the Series F Warrant liabilities through the March 31, 2024 reclassification of Series F Warrant liabilities to equity, which is recorded in other income (expense) on the Consolidated Statements of Comprehensive Loss (see below). The fair value of the Series F Warrants of $7,961,000 was estimated at March 31, 2024, utilizing the Black Scholes Model using the following weighted average assumptions: dividend yield 0%; remaining term of 3.90 years; equity volatility of 110.0%; and a risk-free interest rate of 4.31%.

On May 14, 2024, the Company entered into an Amendment (the “Series F Warrant Amendment”) with the Series F Investors in the February 2023 Offering, effective as of March 31, 2024. The Series F Warrant Amendment modified certain terms of the Series F Warrants relating to the rights of the holders of the Series F Warrants to provide that, in the event of a Fundamental Transaction (as defined in the Series F Warrants) that is not within the Company’s control, including the Fundamental Transaction not being approved by the Company’s Board of Directors, the holder of the Series F Warrant shall only be entitled to receive from the Company or any successor entity the same type or form of consideration (and in the same proportion), at the Black Scholes Value of the unexercised portion of such Series F Warrant, that is being offered and paid to the holders of the Company’s common stock in connection with the Fundamental Transaction, whether that consideration be in the form of cash, stock or any combination thereof, or whether the holders of Common Stock are given the choice to receive from among alternative forms of consideration in connection with the Fundamental Transaction; provided, further, that if holders of Common Stock of the Company are not offered or paid any consideration in such Fundamental Transaction, such holders of Common Stock will be deemed to have received common stock of the successor entity (which such successor entity may be the Company following such Fundamental Transaction) in such Fundamental Transaction. The modification resulted in the reclassification of the Series F Warrants to be considered equity classified as they were no longer in the scope of ASC 815. In accordance with ASC 815-40, the Company remeasured the Series F Warrant liabilities at $7,961,000 fair value as of March 31, 2024, the effective date of the modification, and recognized the $7,094,000 loss on the change in fair value and reclassified the $7,961,000 fair value of the Series F Warrants to additional paid-in capital as of March 31, 2024.

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 2,780,839 shares of Common Stock, with an initial exercise price of $1.816 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 2,780,839 shares of Common Stock, with an initial exercise price of $1.816 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, the Series F-1 Exercise Price was adjusted to $0.1832 per share pursuant to the full ratchet anti-dilution provisions contained in the Series F-1 Warrants.

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.

On August 16, 2024, the Company entered into (i) an Amendment (the “Series F-1 Long Term Warrant Amendment”) with the Series F-1 Investors, effective as of June 30, 2024 relating to the Series F-1 Long Term Warrants, and (ii) an Amendment (the “Series F-1 Short Term Warrant Amendment” and, together with the Series F-1 Long Term Warrant Amendment, the “Series F-1 Warrant Amendments”) with the Series F-1 Investors, effective as of June 30, 2024 relating to the Series F-1 Short Term Warrants. The Series F-1 Warrant Amendments modified certain terms of the Series F-1 Warrants relating to the rights of the holders of the Series F-1 Warrants to provide that, in the event of a Fundamental Transaction (as defined in the Series F-1 Warrants) that is not within the Company’s control, including the Fundamental Transaction not being approved by the Company’s Board of Directors, the holder of the Series F-1 Warrant shall only be entitled to receive from the Company or any successor entity the same type or form of consideration (and in the same proportion), at the Black Scholes Value of the unexercised portion of such Series F-1 Warrant, that is being offered and paid to the holders of the Company’s Common Stock in connection with the Fundamental Transaction, whether that consideration be in the form of cash, stock or any combination thereof, or whether the holders of Common Stock are given the choice to receive from among alternative forms of consideration in connection with the Fundamental Transaction; provided, further, that if holders of Common Stock of the Company are not offered or paid any consideration in such Fundamental Transaction, such holders of Common Stock will be deemed to have received common stock of the successor entity (which such successor entity may be the Company following such Fundamental Transaction). Additionally, the Series F-1 Warrant Amendments amend the definition of Black Scholes Value related to the volatility input which is now an expected volatility equal to the 30 day volatility, obtained from the “HVT” function on Bloomberg (determined utilizing a 365 day annualization factor) as of the trading day immediately following the earliest to occur of (1) the public disclosure of the applicable Fundamental Transaction and (2) the date of a holder’s request. The modification resulted in the reclassification of the Series F-1 Warrants to be considered equity classified as they were no longer in the scope of ASC 815. In accordance with ASC 815-40, the Company remeasured the Series F-1 Warrants at fair value as of July 25, 2024 ($6,965,000), and recognized the $6,000 change in fair value as a non-cash loss and reclassified the Series F-1 Warrants to additional paid-in capital as of July 25, 2024.

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 Comprehensive Loss. 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 $1.90 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

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 Comprehensive Loss. 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 $1.90 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.

Pursuant to the Series G Private Placement, the Company issued to investors (i) the Series G Long-Term Warrants to purchase 4,928,416 shares of Common Stock, with an initial exercise price of $1.816 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 4,928,416 shares of Common Stock, with an initial exercise price of $1.816 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 August 16, 2024, the Company entered into (i) an Amendment (the “Series G Long Term Warrant Amendment”) with the Series G Investors, effective as of June 30, 2024, relating to the Series G Long Term Warrants, and (ii) an Amendment (the “Series G Short Term Warrant Amendment” and, together with the Series G Long Term Warrant Amendment, the “Series G Warrant Amendments”) with the Series G Investors, effective as of June 30, 2024, relating to the Series G Short Term Warrants. The Series G Warrant Amendments modified certain terms of the Series G Warrants relating to the rights of the holders of the Series G Warrants to provide that, in the event of a Fundamental Transaction (as defined in the Series G Warrants) that is not within the Company’s control, including the Fundamental Transaction not being approved by the Company’s Board of Directors, the holder of the Series G Warrant shall only be entitled to receive from the Company or any successor entity the same type or form of consideration (and in the same proportion), at the Black Scholes Value (as defined in the Series G Warrants) of the unexercised portion of such Series G Warrant, that is being offered and paid to the holders of the Company’s Common Stock in connection with the Fundamental Transaction, whether that consideration be in the form of cash, stock or any combination thereof, or whether the holders of Common Stock are given the choice to receive from among alternative forms of consideration in connection with the Fundamental Transaction; provided, further, that if holders of Common Stock of the Company are not offered or paid any consideration in such Fundamental Transaction, such holders of Common Stock will be deemed to have received common stock of the successor entity (which such successor entity may be the Company following such Fundamental Transaction). Additionally, the Series G Warrant Amendments amend the definition of Black Scholes Value related to the volatility input which is now an expected volatility equal to the 60 day volatility, obtained from the “HVT” function on Bloomberg (determined utilizing a 365 day annualization factor) as of the trading day immediately following the earliest to occur of (1) the public disclosure of the applicable Fundamental Transaction and (2) the date of a holder’s request. The modification resulted in the reclassification of the Series G Warrants to be considered equity classified as they were no longer in the scope of ASC 815. In accordance with ASC 815-40, the Company remeasured the Series G Warrants at fair value as of July 25, 2024 ($12,343,000) and recognized the $11,000 change in fair value as a non-cash loss and reclassified the Series G Warrants to additional paid-in capital as of July 25, 2024.
