Note 13 Warrants

DHAC Assumed Warrants

The Company has analysed the public warrants, private warrants, Bridge Warrants (as defined below), September 2024 Warrants and the Extension Warrants and determined they are considered to be freestanding instruments and do not exhibit any of the characteristics in ASC 480 and therefore are not classified as liabilities under ASC 480. The warrants meet all of the requirements for equity classification under ASC 815 and therefore are classified in equity. Below is a summary of the warrants issued and outstanding:

Public and Private Warrants

There are 12,057,000 public and private warrants issued and outstanding as of December 31, 2024, which were assumed as a result of the Business Combination. . As of December 31, 2025, there are 10,460,565 public and private warrants issued and outstanding. The warrants were issued by DHAC in connection with DHAC’s Initial Public Offering. Each warrant entitles the registered holder to purchase one (1) share of common stock at a price of $11.50 per whole share, subject to adjustment as discussed below, at any time commencing on the later of 30 days after the completion of an initial business combination or 12 months from the closing of the Initial Public Offering.

However, no warrants will be exercisable for cash unless the Company has an effective and current registration statement covering the shares of common stock issuable upon exercise of the warrants and a current prospectus relating to such shares of common stock. Notwithstanding the foregoing, if a registration statement covering the shares of common stock issuable upon exercise of the public warrants is not effective within a specified period following the consummation of the initial business combination, warrant holders may, until such time as there is an effective registration statement and during any period when the Company shall have failed to maintain an effective registration statement, exercise warrants on a cashless basis pursuant to the exemption provided by Section 3(a)(9) of the Securities Act, provided that such exemption is available. If that exemption, or another exemption, is not available, holders will not be able to exercise their warrants on a cashless basis. In the event of such cashless exercise, each holder would pay the exercise price by surrendering the warrants for that number of shares of common stock equal to the quotient obtained by dividing (x) the product of the number of shares of common stock underlying the warrants, multiplied by the difference between the exercise price of the warrants and the “fair market value” (defined below) by (y) the fair market value. The “fair market value” for this purpose will mean the average reported last sale price of the shares of common stock for the five trading days ending on the trading day prior to the date of exercise. The warrants will expire on the fifth anniversary of the completion of an initial business combination, at 5:00 p.m., New York City time, or earlier upon redemption or liquidation.

The Private Placement Warrants are identical to the warrants underlying the units in the Initial Public Offering. The Company may call the warrants for redemption, in whole and not in part, at a price of $0.01 per warrant,

The right to exercise will be forfeited unless the warrants are exercised prior to the date specified in the notice of redemption. On and after the redemption date, a record holder of a warrant will have no further rights except to receive the redemption price for such holder’s warrant upon surrender of such warrant.

The redemption criteria for the warrants have been established at a price which is intended to provide warrant holders a reasonable premium to the initial exercise price and provide a sufficient differential between the then-prevailing share price and the warrant exercise price so that if the share price declines as a result of the redemption call, the redemption will not cause the share price to drop below the exercise price of the warrants.

If the Company calls the warrants for redemption as described above, the Company’s management will have the option to require all holders that wish to exercise warrants to do so on a “cashless basis.” In such event, each holder would pay the exercise price by surrendering the warrants for that number of shares of common stock equal to the quotient obtained by dividing (x) the product of the number of shares of common stock underlying the warrants, multiplied by the difference between the exercise price of the warrants and the “fair market value” (defined below) by (y) the fair market value. The “fair market value” for this purpose shall mean the average reported last sale price of the shares of common stock for the five trading days ending on the third trading day prior to the date on which the notice of redemption is sent to the holders of warrants.

The warrants were issued in registered form under a warrant agreement between Continental Stock Transfer & Trust Company, as warrant agent, and the Company. The warrant agreement provides that the terms of the warrants may be amended without the consent of any holder to cure any ambiguity or correct any defective provision or to make any other change that does not adversely affect the interests of the registered holders. For any other change, the warrant agreement requires the approval by the holders of at least a majority of the then outstanding public warrants if such amendment is undertaken prior to or in connection with the consummation of a business combination or at least a majority of the then outstanding warrants if the amendment is undertaken after the consummation of a business combination.

The exercise price and number of shares of common stock issuable on exercise of the warrants may be adjusted in certain circumstances including in the event of a stock dividend, extraordinary dividend or recapitalization, reorganization, merger or consolidation. However, except as described below, the warrants will not be adjusted for issuances of shares of common stock at a price below their respective exercise prices. If (x) the Company issues additional shares of common stock or equity-linked securities for capital raising purposes in connection with the closing of the initial business combination at an issue price or effective issue price of less than $9.20 per share of common stock (with such issue price or effective issue price to be determined in good faith by the board of directors, and in the case of any such issuance to the Company’s Sponsor, initial stockholders or their affiliates, without taking into account any founders’ shares held by them prior to such issuance), (y) the aggregate gross proceeds from such issuances represent more than 60% of the total equity proceeds, and interest thereon, available for the funding of the initial business combination on the date of the consummation of the initial business combination (net of redemptions), and (z) the Market Value is below $9.20 per share, the exercise price of the warrants will be adjusted (to the nearest cent) to be equal to 115% of the greater of (i) the Market Value or (ii) the price at which the Company issue the additional shares of common stock or equity-linked securities and the $18.00 per share redemption trigger price described above will be adjusted (to the nearest cent) to be equal to 180% of the Market Value. The warrants may be exercised upon surrender of the warrant certificate on or prior to the expiration date at the offices of the warrant agent, with the exercise form on the reverse side of the warrant certificate completed and executed as indicated, accompanied by full payment of the exercise price, by certified or official bank check payable to the Company, for the number of warrants being exercised. The warrant holders do not have the rights or privileges of holders of shares of common stock and any voting rights until they exercise their warrants and receive shares of common stock. After the issuance of shares of common stock upon exercise of the warrants, each holder will be entitled to one vote for each share held of record on all matters to be voted on by stockholders.

Warrant holders may elect to be subject to a restriction on the exercise of their warrants such that an electing warrant holder would not be able to exercise their warrants to the extent that, after giving effect to such exercise, such holder would beneficially own in excess of 9.8% of the shares of common stock outstanding.

No fractional shares will be issued upon exercise of the warrants. If, upon exercise of the warrants, a holder would be entitled to receive a fractional interest in a share, the Company will, upon exercise, round up to the nearest whole number the number of shares of common stock to be issued to the warrant holder.

Bridge Warrants

In connection with the closing of the Business Combination, for accounting purposes, it was treated that the Company also assumed the Bridge Warrants which were outstanding with DHAC. On October 6, 2022, 173,913 warrants were issued pursuant to the Bridge Purchase Agreement. The purchase right represented by the Bridge Warrants shall terminate on or before 5:30 p.m., Pacific Time, on the date five years from the date of issuance (the “Expiration Date”). The exercise price at which the Bridge Warrants may be exercised shall be $11.50 per share of Common Stock. If at any time after the date of issuance of the Bridge Warrants there is no effective registration statement available for the resale of shares of Common Stock held by the holder, the Bridge Warrants may be exercised by cashless exercise. In lieu of any fractional share to which the holder would otherwise be entitled, the Company shall make a cash payment equal to the Exercise Price multiplied by such fraction. Except as provided in the Bridge Warrant, the Bridge Warrant does not entitle its holder to any rights of a shareholder of the Company.

During the term the Bridge Warrants are exercisable, the Company will reserve from its authorized and unissued Common Stock a sufficient number of shares to provide for the issuance of Common Stock upon the exercise of the Bridge Warrant and, from time to time, will take all steps necessary to amend its Certificate of Incorporation to provide sufficient reserves of shares of Common Stock issuable upon exercise of the Bridge Warrants. All shares that may be issued upon the exercise of rights represented by the Bridge Warrants and payment of the Exercise Price will be free from all taxes, liens and charges in respect of the issue thereof (other than taxes in respect of any transfer occurring contemporaneously or otherwise specified in the Bridge Warrants). Prior to the Expiration Date, the Exercise Price and the number of shares of Common Stock purchasable upon the exercise of the Bridge Warrants are subject to adjustment from time to time upon the occurrence of any of the following events:

The Bridge Warrants are governed by, and construed in accordance with, the laws of the State of Delaware, without regard to principles of conflicts of law. The Company and the holders of the Bridge Warrants consent to the exclusive jurisdiction of the federal courts of the United States sitting in Delaware.

Extension Warrants

In connection with the closing of the Business Combination, the Company also assumed the Extension Warrants which were outstanding with DHAC. On May 5, 2023, the Company issued 26,086 warrants pursuant to the Extension Purchase Agreement. The purchase right represented by the Extension Warrants shall terminate on the date five years from the date of issuance (the “Expiration Date”). The exercise price at which the Extension Warrants may be exercised shall be $11.50 per share of Common Stock. If at any time after the date of issuance of the Extension Warrants there is no effective registration statement available for the resale of shares of Common Stock held by the holder, the Extension Warrants may be exercised by cashless exercise. In lieu of any fractional share to which the holder would otherwise be entitled, the Company shall make a cash payment equal to the exercise price multiplied by such fraction. Except as provided in the Extension Warrants, the Extension Warrant does not entitle its holder to any rights of a stockholder of the Company.

During the term, the May 2023 Warrants are exercisable, the Company will reserve from its authorized and unissued Common Stock a sufficient number of shares to provide for the issuance of Common Stock upon the exercise of the May 2023 Warrant and, from time to time, will take all steps necessary to amend its Certificate of Incorporation to provide sufficient reserves of shares of Common Stock issuable upon exercise of the Extension Warrants. All shares that may be issued upon the exercise of rights represented by the Extension Warrants and payment of the exercise price will be free from all taxes, liens and charges in respect of the issue thereof (other than taxes in respect of any transfer occurring contemporaneously or otherwise specified in the Extension Warrants). Prior to the Expiration Date, the exercise price and the number of shares of Common Stock purchasable upon the exercise of the Extension Warrants are subject to adjustment from time to time upon the occurrence of any of the following events:

The Extension Warrants are governed by, and construed in accordance with, the laws of the State of Delaware, without regard to principles of conflicts of law. The Company and the holders of the Extension Warrants consent to the exclusive jurisdiction of the federal courts of the United States sitting in Delaware.

September 2024 Warrants

On September 30, 2024, the Company executed a securities purchase agreement (the “SPA”) with an accredited and institutional investor (the “Investor”). Pursuant to the SPA, the Company issued to the Investor warrants (the “September 2024 Warrants”) with an exercise period of five years to purchase up to 740,741 shares of Company Common Stock at an exercise price of $2.25 per share. The exercise price includes standard antidilution adjustments as well as adjustment in the event the Company sells or issues shares of common stock at a price less than the exercise price (a down-round event). The Company assessed the warrant as a freestanding financial instrument and determined it did not include any provisions which would require liability classification under ASC 480, and that it met the requirements to be considered indexed to the Company’s own stock and the additional equity classification requirements under ASC 815-40. As such, the Company classified the warrant in stockholders’ equity (deficit) upon its issuance.

During the term, the September 2024 Warrants are exercisable, the Company will reserve from its authorized and unissued Common Stock a sufficient number of shares to provide for the issuance of Common Stock upon the exercise of the September 2024 Warrants and, from time to time, will take all steps necessary to amend its Certificate of Incorporation to provide sufficient reserves of shares of Common Stock issuable upon exercise of the September 2024 Warrants. All shares that may be issued upon the exercise of rights represented by the September 2024 Warrants and payment of the exercise price will be free from all taxes, liens and charges in respect of the issue thereof (other than taxes in respect of any transfer occurring contemporaneously or otherwise specified in the September 2024 Warrants). Prior to the Expiration Date, the exercise price and the number of shares of Common Stock purchasable upon the exercise of the September 2024 Warrants are subject to adjustment from time to time upon the occurrence of any of the following events:

Warrant Exchange Agreement

On October 29, 2025, the Company also entered into a warrant exchange arrangement with Alta Partners (“Alta”) relating to holdings of its Public Warrants, which were issued in connection with the Company’s initial public offering. Pursuant to the arrangement, Alta exchanged a total of 1,560,000 Public Warrants for 1,508,052 shares of the Company’s Common Stock, representing an exchange ratio of approximately 0.9667 shares per warrant. Alta continues to hold 706,533 warrants exercisable for Common Stock at an exercise price of $11.50 per share. In connection with the exchange, the Company recognized proceeds of $1,500,003 in the consolidated statements of stockholders’ (deficit) equity.

Private Placement with Armistice 

On November 25, 2025, the Company entered into a securities purchase agreement with Armistice Capital (“Armistice”) pursuant to which Armistice agreed to purchase an aggregate of 9,836,065 shares of the Company’s Common Stock or, at Armistice’s election, pre-funded warrants exercisable at $0.0001 per share in lieu thereof, together with common warrants to purchase up to 19,672,130 common shares. The securities were sold at a combined purchase price of $0.61 per share (or pre-funded warrant) and accompanying common warrants, for gross proceeds of $5,999,016. The private placement closed on December 1, 2025. In connection with the exchange, the Company recognized proceeds of $5,519,085, net of issuance cost, in additional paid-in capital. The Company incurred $479,931 in legal fees related to the transaction, which were treated as share issuance costs and recorded as a reduction to the proceeds.
