NOTE 5 — Stockholders’ Equity

ChEF Purchase Agreement

On September 29, 2025, the Company entered into a ChEF purchase agreement (the “ChEF Agreement”) and registration rights agreement (the “Registration Rights Agreement”), each with Chardan Capital Markets LLC (“Chardan”) related to a “ChEF,” Chardan’s committed equity facility.

Pursuant to the ChEF Agreement, the Company has the right from time to time at its option to sell to Chardan up to the lesser of (i) $500,000 in aggregate gross purchase price of newly issued shares of the Company’s common stock, par value $0.001 per share (the “Common Stock”), and (ii) the Exchange Cap (as defined in the ChEF Agreement), subject to certain conditions and limitations set forth in the Purchase Agreement and applicable Nasdaq listing rules. The Company is under no obligation to sell any securities to Chardan under the ChEF Agreement.

While there are distinct differences, the facility pursuant to the ChEF Agreement is structured similarly to a traditional “at-the-market” equity facility, insofar as it allows the Company to raise primary equity capital on a periodic basis. The net proceeds from any sales under the ChEF Purchase Agreement will depend on the frequency with, and prices at, which the shares of our common stock are sold to Chardan. The registration statement in connection with the facility became effective on October 29, 2025.

Use of Proceeds

The Company expects to use a minimum of 33% of proceeds from any sales under the ChEF Agreement for pre-payment of the promissory note in the original principal amount of $2,755 issued by the Company to Streeterville Capital, LLC on July 11, 2025, pursuant to the July Purchase Agreement, until and unless such note is repaid in full. The Company intends to use any remaining proceeds for operations, to support the overall business strategy, for working capital, and general corporate purposes.

Registered Public Offering

On July 2, 2025, the Company consummated a best-efforts public offering (the “Offering”) of 411,111 shares of its common stock, as adjusted for the Reverse Stock Splits, at a public offering price of $13.50 per share, as adjusted for the Reverse Stock Splits. In connection with the Offering, the Company entered into a securities purchase agreement with certain investor signatories thereto for the purchase of shares of common stock described above.

Roth (the “Placement Agent”) served as the exclusive placement agent in connection with the Offering. The Company paid the Placement Agent a cash fee of 7.0% of the aggregate gross proceeds raised at the closing of the Offering, and reimbursement of certain expenses and legal fees in the amount of $100. The Company also issued to designees of the Placement Agent warrants to purchase up to an aggregate of 11,604 shares of Common Stock, as adjusted for the Reverse Stock Splits (the “Placement Agent Warrants”). The Placement Agent Warrants have an exercise price of $13.50 per share, as adjusted for the Reverse Stock Splits, are not exercisable until January 2, 2026, and expire on July 2, 2030. The exercise prices of the Placement Agent Warrants are subject to appropriate adjustment in the event of stock dividends, stock splits, stock combinations, reorganizations or similar events affecting the Common Stock. Subject to limited exceptions, a holder of Placement Agent Warrants will not have the right to exercise any portion of its Warrants if the holder (together with such holder’s affiliates, and any persons acting as a group together with such holder or any of such holder’s affiliates) would beneficially own a number of shares of common stock in excess of 4.99% (or, upon election by a holder prior to the issuance of any Warrants, 9.99%) of the shares of common stock then outstanding. At the holder’s option, upon notice to the Company, the holder may increase or decrease this beneficial ownership limitation not to exceed 9.99% of the shares of Common Stock then outstanding. The Purchase Agreement contains customary representations, warranties, and covenants by the Company. It also provides for customary indemnification for losses or damages arising out of or in connection with the Offering, including for liabilities under the Securities Act, other obligations of the parties and termination provisions. 

The shares of common stock and the Placement Agent Warrants described above and the underlying shares of common stock were offered pursuant to a Registration Statement on Form S-1, as amended (File No. 333-288221), which was declared effective by the SEC on June 30, 2025.

The net proceeds of the Offering are approximately $4,800, after deducting the Placement Agent fees and expenses and other estimated offering expenses payable by the Company. The Company used the net proceeds of the Offering for overall business strategy, for working capital purposes and for general corporate purposes.

ATM Offering

On August 6, 2024, the Company entered into a sales agreement (the “Sales Agreement”) with Roth Capital Partners, LLC (“Roth”). Pursuant to the Sales Agreement, the Company may sell, at its option, shares of common stock through Roth, as sales agent. Sales of shares of the Company’s common stock made pursuant to the Sales Agreement are being made under the Registration Statement on Form S-3 filed on April 9, 2024 (File No. 333-278577), which was declared effective by the SEC on May 3, 2024. Subject to the terms and conditions of the Sales Agreement, Roth may sell the shares, if any, only by methods deemed to be an “at the market” offering as defined in Rule 415(a)(4) promulgated under the Securities Act. Roth will be entitled to compensation at a commission rate of 3% of the gross sales price per share sold through it under the Sales Agreement. The Company agreed to provide Roth with customary indemnification and contribution rights, including for liabilities under the Securities Act. In addition, the Company is required to reimburse Roth for certain specified expenses in connection with entering into the Sales Agreement.

During the nine months ended September 30, 2025, a total of 193,405 shares of common stock, as adjusted for the Reverse Stock Splits, were sold under the Sales Agreement for net proceeds of $8,229, after payment of commission fees and other related expenses of $258. In the second quarter of 2025, the Company completed its sales of shares of common stock under the Sales Agreement and the ATM program was terminated.

Shareholder Rights Plan

On April 21, 2025, the Board declared a dividend of one preferred share purchase right (“Right”) for each outstanding share of common stock, par value $0.001 per share, of the Company, and adopted a stockholder rights plan, as set forth in the Rights Agreement, dated as of April 21, 2025 (the “Rights Agreement”), by and between the Company and Equiniti Trust Company, LLC, a New York limited liability company, as rights agent. The dividend is payable to stockholders of record of the Company as of the close of business on May 2, 2025.

Each Right will allow its holder to purchase from the Company one one-thousandth of a share of Series A Junior Participating Preferred Stock (the “Preferred Shares”), par value $0.001 per share, for $4.00 (the “Purchase Price”), once the Rights become exercisable. The Purchase Price payable, and the number of Preferred Shares or other securities or other property issuable upon exercise of the Rights will be subject to adjustment from time to time to prevent dilution in the event of a stock dividend on, or a subdivision, combination or reclassification of, the Preferred Shares. The Rights are exercisable only if a person or group acquires 15.5% or more of the Company’s outstanding common stock (an amount of “less than 20%” in the case of a passive institutional investor as described in the Rights Plan), commences tender or exchange offer, or a similar event, as described in detail in the Purchase Agreement.
