Stockholders’ Equity

(7) Stockholders’ Equity

 

(a) Preferred Stock

 

The Company is authorized to issue 5,000,000 shares of $0.01 par value preferred stock with such designations, rights and preferences as may be determined by the Board. Of our authorized preferred stock, 4,000,000 shares have been designated as Series A Junior Participating Preferred Stock and 10,000 shares have been designated as Series B Convertible Preferred Stock.

 

Series A Junior Participating Preferred Stock

 

On May 10, 2023, the Company filed a Certificate of Increase in Delaware, increasing the number of preferred stock designated as Series A Junior Participating Preferred Stock to 4,000,000 from 250,000 shares. As of December 31, 2024, there were no Series A Junior Participating Preferred Stock outstanding.

 

Series B Convertible Preferred Stock

 

The Company has designated 10,000 shares of its preferred stock as Series B Convertible Preferred Stock (the “Preferred Stock”). Each share of Preferred Stock has a par value of $0.01 per share and a stated value equal to $1,000 (the “Stated Value”). The shares of Preferred Stock shall initially be issued and maintained in the form of securities held in book-entry form and the Depository Trust Company or its nominee (“DTC”) shall initially be the sole registered holder of the shares of Preferred Stock.

 

Each share of Preferred Stock shall be convertible, at any time and from time to time from and after the Original Issue Date at the option of the Holder thereof or at any time and from time to time on or after the second anniversary of the Original Issue Date at the option of the Corporation, into that number of shares of common stock (subject in each case to the limitations determined by dividing the Stated Value of such share of Preferred Stock by the Conversion Price). The conversion price for the Preferred Stock shall be equal to $0.20, subject to adjustment herein (the “Conversion Price”).

 

Pursuant to a registration statement relating to a rights offering (the “Rights Offering”) declared effective by the SEC on February 14, 2019, AIM distributed to its holders of common stock and to holders of certain options and redeemable warrants as of February 14, 2019, at no charge, one non-transferable subscription right for each share of common stock held or deemed held on the record date. Each right entitled the holder to purchase one unit, at a subscription price of $1,000 per unit, consisting of one share of Series B Convertible Preferred Stock with a face value of $1,000 (and immediately convertible into common stock at an assumed conversion price of $8.80) and 114 warrants with an assumed exercise price of $8.80. The redeemable warrants are exercisable for five years after the date of issuance. The net proceeds realized from the rights offering were approximately $4,700,000. As of December 31, 2024, 689 shares of Series B Convertible Preferred Stock had expired, and none were converted prior to expiration.

 

 

(b) Common Stock and Equity Finances

 

The Company has authorized shares of 350,000,000 with specific limitations and restrictions on the usage of 8,000,000 of the 350,000,000 authorized shares. As of December 31, 2024, and December 31, 2023, there were 65,526,320 and 49,102,484 shares of common stock issued and outstanding, respectively.

 

Employee Stock Purchase Plan (Not equity compensation)

 

On July 7, 2020, the Board approved a plan pursuant to which all directors, officers, and employees could purchase from the Company up to an aggregate of $500,000 worth of shares at the market price (including subsequent plans, the “Employee Stock Purchase Plan”). Pursuant to NYSE American rules, this plan was effective for a sixty-day period commencing upon the date that the NYSE American approved the Company’s Supplemental Listing Application. The Company created successive new plans following the expiration of the July 7, 2020 plan. The latest plan was approved by the Board on March 6, 2025 and expires in May 2025.

 

During the year ended December 31, 2024, the Company issued a total of 395,713 shares of its common stock at a price ranging from $0.18 to $0.41 for total proceeds of approximately $131,000 as part of the employee stock purchase plan.

 

During the year ended December 31, 2023, the Company issued a total of 419,285 shares of its common stock at a price ranging from $0.31 to $0.67 for total proceeds of approximately $150,500 as part of the employee stock purchase plan.

 

Rights Plan

 

On May 12, 2023, the Company amended and restated its November 14, 2017 Rights Plan with American Stock Transfer & Trust Company as Rights Agent (the “Rights Plan”).

 

Warrants (Rights offering)

 

On September 27, 2019, the Company closed a public offering underwritten by A.G.P./Alliance Global Partners, LLC (the “Offering”) of (i) 1,740,550 shares of common stock; (ii) pre-funded warrants exercisable for 7,148,310 shares of common stock (the “Pre-funded Warrants”), and (iii) warrants to purchase up to an aggregate of 8,888,860 shares of common stock (the “Warrants”). In conjunction with the Offering, we issued a Representative’s Warrant to purchase up to an aggregate of 266,665 shares of common stock (the “Representative’s Warrant”). The shares of common stock and Warrants were sold at a combined Offering price of $0.90, less underwriting discounts and commissions. Each Warrant sold with the shares of common stock represents the right to purchase one share of common stock at an exercise price of $0.99 per share. The Pre-Funded Warrants and Warrants were sold at a combined Offering price of $0.899, less underwriting discounts and commissions. The Pre-Funded Warrants were sold to purchasers whose purchase of shares of common stock in the Offering would otherwise result in the purchaser, together with its affiliates and certain related parties, beneficially owning more than 4.99% of the Company’s outstanding common stock immediately following the consummation of the Offering, in lieu of shares of common stock. Each Pre-Funded Warrant represents the right to purchase one share of common stock at an exercise price of $0.001 per share. The Pre-Funded Warrants are exercisable immediately and may be exercised at any time until the Pre-Funded Warrants are exercised in full. A registration statement on Form S-1, relating to the Offering was filed with the SEC and was declared effective on September 25, 2019, the net proceeds were approximately $7,200,000. During the year ended December 31, 2020, 1,870,000 of the Pre-funded Warrants were exercised and 8,873,960 Warrants were exercised. In addition, on March 25, 2020, the Representative’s Warrant was amended to permit exercise of such warrant to commence on March 30, 2020. These warrants were exercised on March 31, 2020, and an aggregate of 266,665 shares were issued upon exercise of this warrant for gross proceeds of approximately $264,000 and a $46,000 expense for the warrant modification.

 

During the year ended December 31, 2024, 205,000 warrants were exercised, and 5,830,028 warrants expired unexercised. No warrants were exercised during the year ended December 31, 2023. At December 31, 2024 there were no warrants outstanding and December 31, 2023 there were 15,000 warrants outstanding.

 

 

Equity Distribution Agreement

 

On April 19, 2023, we entered into an Equity Distribution Agreement (the “EDA”), with Maxim, pursuant to which we may sell from time to time, shares of our common stock having an aggregate offering price of up to $8.5 million through Maxim, as agent. The amount was subsequently reduced from $8.5 million to $3.1 million. Sales under the EDA were registered under the S-3 Shelf Registration Statement. Under the terms of the Distribution Agreement, Maxim is entitled to a transaction fee at a fixed rate of 3.0% of the gross sales price of shares sold under the EDA. For the year ended December 31, 2024, we sold 1,395,612 shares under the EDA for total gross proceeds of approximately $649,916, which includes a 3.0% fee to Maxim of $19,497. During the year ended December 31, 2023, we sold 598,114 shares under the EDA for total gross proceeds of approximately $344,000, which includes a 3.0% fee to Maxim of $10,326. Subsequent to December 31, 2024, the Company has sold 1,119,106 shares under the EDA for total gross proceeds of approximately $259,800, which includes a 3.0% fee to Maxim of approximately $7,800.

 

Equity Purchase Agreement

 

On March 28, 2024, the Company entered into a purchase agreement and a registration rights agreement with Atlas Sciences, LLC (“Atlas”), pursuant to which Atlas committed to purchase up to $15,000,000 of common stock of the Company for a period of 24 months from the date of the purchase agreement. No assurance can be given as to the actual amount that will be raised pursuant to the purchase agreement.

 

Under the terms of the purchase agreement, the Company, at its sole discretion, shall have the right to issue Put shares to the Investor at 95% of the Market Price of the shares on the day of trade. Sales under the purchase agreement are limited to a daily maximum of the lessor of: $500,000, the Median Daily Trading volume, and a beneficial ownership limitation of 4.99% and a maximum of 19.99% of the outstanding shares at the time of the purchase agreement. In April 2024, the Company filed a registration statement with the SEC on Form S-1 registering a total of 9,975,000 shares for resale pursuant to the Atlas Agreements, consisting of 9,636,400 shares that can be sold by the Company to Atlas and 338,600 shares that were issued to Atlas as Commitment Shares. The registration statement was declared effective on May 1, 2024. As of December 31, 2024, a total of 759,685 shares have been issued pursuant to the purchase agreement for a total of approximately $128,000 after clearing costs. Subsequent to December 31, 2024, a total of 3,082,961 shares have been issued pursuant to the purchase agreement for a total of approximately $398,000 after clearing costs.

 

Securities Purchase Agreement

 

On May 31, 2024, the Company entered into a Securities Purchase Agreement (the “Purchase Agreement”) to complete an offering (the “Transactions”) with a single accredited investor (the “Purchaser”), pursuant to which, on June 3, 2024, the Company issued to the Purchaser, (i) in a registered direct offering, 5,640,958 shares of the Company’s common stock (the “Shares”), par value $0.001 per share (“common stock”) and (ii) in a concurrent private placement, the Company issued to the Purchaser Class A common warrants to purchase an aggregate of up to 5,640,958 shares of its common stock (the “A Warrants”) at an exercise price of $0.363 per share and Class B common warrants to purchase an aggregate of up to 5,640,958 shares of its common stock (the “B “Warrants” and, along with the A Warrants, the “Common Warrants”) at an exercise price of $0.363 per share. The A Warrants and B Warrants are not exercisable for six months after the issuance date and expire, respectively, 24 months and five years and six months after the issuance date. The Common Warrants and the shares of common stock issuable upon the exercise of such warrants are offered pursuant to an exemption from the registration requirements of the Securities Act provided in Section 4(a)(2) of the Securities Act and Rule 506(b) promulgated thereunder.

 

The Shares were offered by the Company pursuant to a shelf registration statement on Form S-3 (File No. 333-262280), which was declared effective on February 4, 2022 (as amended from time to time, the “Registration Statement”).

 

Pursuant to the terms of the Purchase Agreement, subject to certain exceptions, the Company could not issue any equity securities for 60 days following the issuance date, provided that the Company was able to utilize its at-the-market offering program with the Placement Agent after 30 days. Additionally, the Company cannot enter into a variable rate transaction (other than the ATM program with the Placement Agent) for 120 days after the issuance date. In addition, the Company’s executive officers and each of the Company’s directors have entered into lock-up agreements with the Company pursuant to which each of them has agreed not to, for a period of 90 days from the closing of the Transactions, offer, sell, transfer or otherwise dispose of the Company’s securities, subject to certain exceptions.

 

The exercise price of the Common Warrants, and the number of Common Warrant Shares, are subject to adjustment in the event of any stock dividend or split, reverse stock split, recapitalization, reorganization or similar transaction, as described in the Common Warrants. If a Fundamental Transaction (as defined in the Common Warrants) occurs, then the successor entity will succeed to, and be substituted for the Company, and may exercise every right and power that the Company may exercise and will assume all of its obligations under the Common Warrants with the same effect as if such successor entity had been named in the warrant itself. Common Warrant Holders will have additional rights defined in the Common Warrants. The Common Warrants are exercisable on a “cashless” basis only if there is not a current registration statement permitting public resale. In this regard, the Company filed a registration statement to register the resale of the Common Warrant Shares providing for the resale of the Shares issued and issuable upon exercise of the Common Warrants. That registration statement was declared effective by the SEC on July 11, 2024. The Company has agreed to use commercially reasonable efforts to cause such registration statement to keep such registration statement effective at all times until no Purchaser owns any Warrants or Warrant Shares issuable upon exercise thereof.

 

 

Maxim Group LLC acted as the placement agent (the “Placement Agent”) on a “commercially reasonable best efforts” basis, in connection with the Transactions pursuant to the Placement Agency Agreement, dated May 31, 2024 (the “Placement Agency Agreement”), by and between the Company and the Placement Agent. Pursuant to the Placement Agency Agreement, the Placement Agent was paid a cash fee of 8% of the aggregate gross proceeds paid to the Company for the securities sold in the Transactions and reimbursement of certain out-of-pocket expenses.

 

The Company evaluated the Common Warrants under the guidance of ASC 480 – Distinguishing Liabilities from Equity and determined that they were in scope under the guidance as freestanding financial instruments but did not meet the criteria for liability classification and are classified as equity within the consolidated financial statements. Proceeds allocated to such warrants totaled approximately $2.5 million. For the year ended December 31,2024, no Common Warrants were exercised, and all remain outstanding on December 31, 2024 related to this agreement.

 

On September 30, 2024, the Company entered into a Purchase Agreement with the Selling Stockholder as Purchaser, pursuant to which we issued to the Selling Stockholder, (i) in a registered direct offering, 4,653,036 shares of our Common Stock (“Shares”) and (ii) in the concurrent Private Placement, Class C and Class D Warrants, each to purchase an aggregate of up to 4,653,036 Shares (the “Common Warrant Shares”) each with an exercise price of $0.28. The Class C and Class D Warrants together, hereinafter the “Common Warrants”. The purchase price for Shares in the registered direct offering was $0.27 per Share.

 

The Company received aggregate gross proceeds from the Transactions of approximately $1.26 million, before deducting fees to the Placement Agent and other estimated offering expenses payable by us. The Shares were offered by the Company pursuant to a shelf registration statement on Form S-3 (File No. 333-262280), which was declared effective on February 4, 2022. The Common Warrants and the Common Warrant Shares issued in the Private Placement were not registered under the Securities Act. Rather the Common Warrants and the Common Warrant Shares were issued pursuant to the exemption from registration provided in Section 4(a)(2) under the Securities Act and Rule 506(b) promulgated thereunder. The Class C Warrants and the Class D Warrants are not exercisable until December 3, 2024, and will expire, respectively, 24 months and five years and six months after that date.

 

(c) Common Stock Options and Warrants

 

(i) Stock Options

 

The 2018 Equity Incentive Plan, effective September 12, 2018, authorizes the grant of (i) Incentive Stock Options, (ii) Nonstatutory Stock Options, (iii) Stock Appreciation Rights, (iv) Restricted Stock Awards, (v) Restricted Stock Unit Awards, (vi) Performance Stock Awards, (vii) Performance Cash Awards, and (viii) Other Stock Awards. Initially, a maximum of 7,000,000 shares of common stock is reserved for potential issuance pursuant to awards under the 2018 Equity Incentive Plan. Unless sooner terminated, the 2018 Equity Incentive Plan will continue in effect for a period of 10 years from its effective date.

 

The Equity Incentive Plans of 2018 are administered by the Board of Directors. The Plans provide for awards to be made to such Officers, other key employees, non-employee Directors, consultants and advisors of the Company and its subsidiaries as the Board may select.

 

Stock options awarded under the Plans may be exercisable at such times (not later than 10 years after the date of grant) and at such exercise prices (not less than fair market value at the date of grant) as the Board may determine. The Board may provide for options to become immediately exercisable upon a “change in control”, which is defined in the Plans to occur upon any of the following events: (a) the acquisition by any person or group, as beneficial owner, of 20% or more of the outstanding shares or the voting power of the outstanding securities of the Company; (b) either a majority of the Directors of the Company at the annual stockholders meeting has been nominated other than by or at the direction of the incumbent Directors of the Board, or the incumbent Directors cease to constitute a majority of the Company’s Board; (c) the Company’s stockholders approve a merger or other business combination pursuant to which the outstanding common stock of the Company no longer represents more than 50% of the combined entity after the transaction; (d) the Company’s stockholders approve a plan of complete liquidation or an agreement for the sale or disposition of all or substantially all of the Company’s assets; or (e) any other event or circumstance determined by the Company’s Board to affect control of the Company and designated by resolution of the Board as a change in control.

 

The fair value of each option award is estimated on the date of grant using a Black-Scholes-Merton pricing option valuation model. Expected volatility is based on the historical volatility of the price of the Company’s stock. The risk-free interest rate is based on U.S. Treasury issues with a term equal to the expected life of the option and equity warrant. The Company uses historical data to estimate expected dividend yield, life and forfeiture rates. The expected life of the options and equity warrants was estimated based on historical option and equity warrant holders’ behavior and represents the period of time that options and equity warrants are expected to be outstanding. The fair values of the options granted were estimated based on the following weighted average assumptions:

 

 

 

During the year ended December 31, 2023, we issued a total of 400,000 options under the 2018 Equity Incentive Plan, effective September 12, 2018, which will continue in effect for a period of 10 years from its effective date.

 

During the year ended December 31, 2024, we did not issue any options under the 2018 Equity Incentive Plan, However, pursuant to employment agreements for certain executives, 400,000 options were deferred to assure that a sufficient number of shares are available under the 2018 Equity Incentive Plan should they be needed, in the Company opinion, to focus on the Company’s financial resources to further its Ampligen R&D Activities, This deferral is in effect until the Company no longer needs the shares underlying the options reserved from the shares available for issuance under the Plan, or the Company agrees otherwise. During this deferral, the shares underlying the options are still deemed reserved under the Plan.

(ii) Stock Warrants

 

Stock warrants are issued as needed by the Board of Directors and have no formal plan.

 

The fair value of each warrant award is estimated on the date of grant using a Black-Scholes-Merton pricing option valuation model. Expected volatility is based on the historical volatility of the price of the Company’s stock. The risk-free interest rate is based on U.S. Treasury issues with a term equal to the expected life of the warrant. The Company uses historical data to estimate expected dividend yield, life and forfeiture rates. The expected life of the warrants was estimated based on historical option holder’s behavior and represents the period of time that options are expected to be outstanding. No warrants were granted in 2023.
