Convertible Preferred Stock [Text Block] | Note 9. CONVERTIBLE PREFERRED STOCK On March 28, 2024, the Company entered into a securities purchase agreement with the Alzheimer’s Drug Discovery Foundation pursuant to which the Company sold shares of a newly designated series of convertible preferred stock, the Series A Preferred Stock, and warrants to purchase up to 229,057 shares of the Company’s common stock (“ADDF Warrants”) for an aggregate purchase price of $1.75 million. See Note 10, ADDF Warrants. Our Series A Preferred Stock is convertible at the election of the holder at any time after the public announcement by the Company of top-line data from its SIGNAL-AD Alzheimer’s disease study (the “Data Release”) into shares of common stock at a conversion price equal to the greater of (a) $7.77 per share of common stock and (b)(i) the volume weighted average price of the common stock for the last three trading days prior to delivery of the conversion notice if the common stock is traded on a trading market or if its prices are reported on OTCQB or OTCQX, (ii) the most recent bid price of the common stock if it is then traded on The Pink Open Market, or (iii) in all other cases the fair market value of the common stock as determined by an independent appraiser, which conversion right is subject to termination on the last full day preceding the proposed effective date for exercise of the Company’s redemption right or the date fixed for redemption upon a Deemed Liquidation Event (generally defined to include certain fundamental transactions involving the company including a merger or sale of substantially all of the Company’s assets) or on a liquidation, dissolution or winding up of the Company. The Series A Preferred Stock is non-voting, has no mandatory redemption, and carries an annual 5% cumulative dividend, increasing by 2 percentage points each year, which dividend rate shall not exceed 12%. The Series A Preferred Stock will also participate on an as-converted basis in any regular or special dividends paid to holders of our common stock. In addition, the Series A Preferred Stock has a liquidation preference equal to the greater of (i) $175,000 per share, subject to appropriate adjustment in the event of any stock dividend, stock split, combination or other similar recapitalization with respect to the Series A Preferred Stock (the “Original Share Price”), plus any accrued but unpaid dividends thereon, whether or not declared, together with any other dividends declared but unpaid thereon, or (ii) such amount per share as would have been payable had all shares of Series A Preferred Stock been converted into common stock immediately prior to such liquidation, dissolution, winding up or Deemed Liquidation Event. The Company also agreed that so long as the Series A Preferred Stock is outstanding, the Company will not, without the written consent of the holders of 50.1% of the Series A Preferred Stock, (i) amend, alter, or repeal any provision of the Company’s certificate of incorporation or bylaws in a manner adverse to the Series A Preferred Stock or (ii) until March 29, 2026, incur any indebtedness for borrowed money in excess of $1.0 million. The Company has the right to redeem the Series A Preferred Stock at a price equal to the Original Share Price per share at any time after a public announcement of an increase in pepinemab-treated patients relative to placebo-treated patients, with statistical significance having a p-value of less than or equal to 0.05, in the change of the FDG-PET standard uptake value ratio for brain metabolism between baseline and month 12 as assessed by [18F]fluorodeoxyglucose (FDG)-PET in the resting state following administration of 40 mg/kg pepinemab or placebo, as applicable, as described in the protocol for the Company’s SIGNAL-AD Alzheimer’s disease study and the associated Statistical Analysis Plan, provided that (i) the holder is not in possession of any material nonpublic information that was provided by the Company or any of its directors, employees, agents, or affiliates and (ii) there is an effective resale registration statement on file covering the underlying common stock. The Series A Preferred Stock have similar characteristics of an “Increasing Rate Security” as described by SEC Staff Accounting Bulletin Topic 5Q, Increasing Rate Preferred Stock. As a result, the discount on Series A Preferred Stock is considered an unstated dividend cost that is amortized over the period preceding commencement of the perpetual dividend using the effective interest method, by charging imputed dividend cost against retained earnings, or additional paid in capital in the absence of retained earnings and increasing the carrying amount of the Series A Preferred Stock by a corresponding amount, to accrete the initial recognized value to its expected settlement value on the expected redemption date. The amortization in each period is the amount which, together with the stated dividend in the period, results in a constant rate of effective cost with regard to the carrying amount of the Series A Preferred Stock. Each share of Series A Preferred Stock contains redemption features which allow for the redemption of the Series A Preferred Stock in the event of a voluntary or involuntary liquidation, dissolution, winding up of the Company, or Deemed Liquidation Event, as defined in the certificate of designations (“liquidation events”). Upon the occurrence of such qualifying liquidation event, the Series A Preferred Stock holder shall be entitled to receive cash or assets of the Company before any distribution or payment may be made to or set apart for the holders of common stock in an amount per share of Series A Preferred Stock equal to, or greater of, (i) $175,000 plus all accrued and unpaid dividends thereon, whether or not declared (the "Liquidation Preference”); or (2) the amount per share the holder would receive if such holder converted the shares of Series A Preferred Stock immediately prior to the date of such payment, with certain additional conditions. The embedded redemption features require the Company to settle the Series A Preferred Stock at the Liquidation Preference amount upon the occurrence of certain qualifying liquidation events. The holder’s exercise of the embedded conversion feature when the volume weighted average price of the Common Stock for the last three trading days is greater than $7.77, as defined in the certificate of designations, settles the Series A Preferred Stock through the issuance of a variable number of Common Stock in a fixed monetary amount of $175,000 per share. As these embedded features provide for settlement in nominal amounts not associated with its underlyings, the embedded features each meet the definition of a derivative. Under ASC 815, certain contractual terms that meet the accounting definition of a derivative must be accounted for separately from the financial instrument in which they are embedded (Note 2). The Company has concluded that the redemption features and the holder’s option to convert when the volume weighted average price of the Common Stock for the last three trading days is greater than $7.77, as defined in the certificate of designations, constitute embedded derivative and, therefore, require bifurcation from the Series A Preferred Stock. In the event of any liquidation or deemed liquidation event, as defined in the certificate of designations, before any distribution or payment may be made to or set apart for the holders of common stock, the Series A Preferred Stock holder is entitled to receive assets from the Company equal to $175,000 plus all accrued and unpaid dividends thereon, whether or not declared, per share for a total liquidation value of $1.75 million as of September 30, 2024. These redemption provisions were determined to represent embedded derivatives requiring bifurcation from the Series A Preferred Stock. Upon initial issuance, the Company recorded the fair value of the embedded derivatives in the amount of $95 thousand as a derivative asset and premium on the Series A Preferred Stock. The derivative is adjusted to fair value at each reporting period with the change in the fair value recorded in earnings. Accordingly, based upon the relative fair values of the instruments on the date of issuance, the Company allocated approximately $0.57 million of the gross proceeds to the ADDF Warrants and $1.18 million of the gross proceeds to the Series A Preferred Stock which is net of $95 thousand, attributed to the derivative asset. |
