​

On February 24, 2026, the Company entered into the February 2026 Purchase Agreement with a certain accredited investor (the “February 2026 Purchaser”) for the issuance and sale in a private placement of an aggregate of (i) 31,333 shares of the Company’s newly-designated Series H Convertible Preferred Stock, par value of $0.01 per share and a stated value of $1,000 per share (the “Series H Preferred Stock”), initially convertible into up to 66,665,957 shares of common stock (the “Series H Conversion Shares”), at an initial conversion price of $0.47 per share, subject to adjustment for certain customary adjustments, and (ii) the warrants (the “Series H Warrants”) to purchase up to 66,665,957 shares of common stock, at an initial exercise price of $0.345 per share, subject to adjustment for certain customary adjustments, for aggregate gross proceeds of approximately $31,300. The Series H Warrants expire three years from the date of issuance. The February 2026 Private Placement closed in two tranches, with 30,832 shares of Series H Preferred Stock and 65,600,000 Series H Warrants issued on February 27, 2026 (the “First Closing”), and 501 shares of Series H Preferred Stock and 1,065,957 Series H Warrants issued on March 3, 2026 (the “Second Closing”, and collectively with the First Closing, the “Closing”).

​

In connection with the February 2026 Private Placement, pursuant to a placement agency agreement (the “Placement Agency Agreement”), dated as of February 24, 2026, by and between the Company and Dominari Securities LLC (the “Placement Agent”), the Company engaged the Placement Agent to act as an exclusive placement agent in connection with the February 2026 Private Placement and agreed to (i) pay to the Placement Agent (a) a cash fee equal to 8% of the gross proceeds of the February 2026 Private Placement and (b) reimbursements and payments of certain expenses, including non-accountable expense allowance equal to 1% of the gross proceeds raised in the February 2026 Private Placement and reasonable out-of-pocket expenses, not to exceed $250, and (ii) issue to the Placement Agent warrants (the “Placement Agent Warrants”) to purchase up to an aggregate number of shares of Common Stock equal to 8% of the aggregate number of shares of common stock underlying the securities issued in the February 2026 Private Placement, with terms identical to the Series H Warrants, except that the Series H Placement Agent Warrants have a term of five (5) years from the date of issuance. The Placement Agency Agreement contains customary representations, warranties and agreements of the parties, and customary indemnification obligations of the Company.

​

Series H Preferred Stock

​

The terms of the Series H Preferred Stock are set forth in the Series H Certificate of Designations. The shares of Series H Preferred Stock are convertible into the Series H Conversion Shares at the election of the holders of the Series H Preferred Stock (the “Holders”) at any time at an initial conversion price of $0.47 per share (the “Series H Conversion Price”). The

Series H Conversion Price is subject to customary adjustments for stock dividends, stock splits, reclassifications, stock combinations and the like.

​

A Holder of the Series H Preferred Stock may not convert any portion of the Series H Preferred Stock to the extent that the Holder, together with its affiliates, would beneficially own more than 4.99% of the Company’s outstanding shares of Common Stock immediately after conversion, except that upon at least 61 days’ prior notice from the Holder to the Company, the Holder may increase the beneficial ownership limitation to up to 9.99% of the number of shares of Common Stock outstanding immediately after giving effect to the conversion.

​

Pursuant to the Series H Certificate of Designations, so long as any shares of the Series H Preferred Stock are outstanding, the Company may not, directly or indirectly, redeem, or declare or pay any cash dividend or distribution on, any securities of the Company without the prior express written consent of the Required Holders (as defined in the Series H Certificate of Designations). In the event that dividends are consented to by the Required Holders, the Holders of the Series H Preferred Stock shall be entitled to receive dividends on shares of the Series H 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 may be paid on shares of the Series H Preferred Stock.

​

Except as otherwise provided in the Series H Certificate of Designations or as otherwise required by law, the Series H Preferred Stock will have no voting rights except as provided by law. However, as long as any shares of Series H Preferred Stock are outstanding, the Company may not, without the affirmative vote at a meeting duly called for such purpose, or the written consent without a meeting, of the Required Holders, voting together as a single class, (a) amend or repeal any provision of, or add any provision to, its charter documents, including, without limitation, its Certificate of Incorporation or bylaws, the Series H Certificate of Designation, or file any certificate of designations or articles of amendment of any series of shares of preferred stock, in each case, only if such action would adversely alter or change in any respect the preferences, rights, privileges or powers, or restrictions provided for the benefit, of the Series H Preferred Stock, regardless of whether any such action shall be by means of amendment to the Certificate of Incorporation or by merger, consolidation or otherwise; (b) increase or decrease (other than by conversion) the authorized number of shares of the Series H Preferred Stock; (c) create or authorize (by reclassification or otherwise) any new class or series of shares that has a preference over the Series H Preferred Stock with respect to dividends or the distribution of assets on the liquidation, dissolution or winding up of the Company; (d) pay dividends or make any other distribution on any shares of any capital stock of the Company junior in rank to the Series H Preferred Stock; or (e) whether or not prohibited by the terms of the Series H Preferred Stock, circumvent a right of the Series H Preferred Stock.

​

The Series H Preferred Shares are not mandatorily redeemable and do not embody an unconditional obligation to settle in a variable number of equity shares. As such, the Series H Preferred Stock are classified as permanent equity on the unaudited condensed consolidated balance sheets. The holder’s contingent redemption right in the event of certain deemed liquidation events does not preclude permanent equity classification. The Series H Preferred Shares were determined to be more akin to an equity-like host than a debt-like host for purposes of assessing embedded derivative features for potential bifurcation. The embedded conversion feature is considered to be clearly and closely related to the associated convertible preferred stock host instrument and therefore was not bifurcated from the equity host. 

​

Series H Warrants

​

The exercise price of the Series H Warrants is subject to customary adjustments for stock dividends, stock splits, reclassifications and the like. A holder of the Series H Warrants may not exercise any portion of such holder’s Warrants to the extent that the holder, together with its affiliates, would beneficially own more than 4.99% of the Company’s outstanding shares of Common Stock immediately after exercise, except that upon at least 61 days’ prior notice from the holder to the Company, the holder may increase the beneficial ownership limitation to up to 9.99% of the number of shares of Common Stock outstanding immediately after giving effect to the exercise.

​

The Company assessed the Series H Warrants under ASC 480 and ASC 815 and determined that they met the requirements to be classified in stockholders’ equity upon issuance.

​

Pursuant to the Placement Agency Agreement, the Company issued to the Placement Agent  the Series H Placement Agent Warrants to purchase 5,333,277 shares of Common Stock with the same terms as the Series H Warrants except that the Series H Placement Agent Warrants have a term of five (5) years from the date of issuance. The Series H Placement Agent Warrants are within the scope of ASC 718 pursuant to ASC 718-10-20 and were determined to qualify for equity classification upon issuance. The total aggregate fair value of the Series H Placement Agent Warrants between the First Closing and the Second Closing of approximately $7,152 was included as a component of total transaction costs for the February 2026 Private Placement and was accordingly recorded in equity. The issuance date fair value of the Series H Placement Agent Warrants issued in the First Closing of $7,048 was determined using the Black Scholes Model using the following weighted average assumptions: the fair value of the Company’s common stock per share of $1.49; remaining term of 5 years; equity volatility of 101%; and a risk-free interest rate of 3.5%. The issuance date fair value of the Series H Placement Agent Warrants issued in the Second Closing of $104 was determined using the Black Scholes Model using the following weighted average assumptions: the fair value of the Company’s common stock per share of $1.37; remaining term of 5 years; equity volatility of 100%; and a risk-free interest rate of 3.6%.

​

Transaction costs totaling $10,216 were incurred related to the February 2026 Private Placement consisting of cash expenses for placement agent fees, legal fees, and accounting costs related to the financing, as well as the fair value of Series H Placement Agent Warrants. Net proceeds from the February 2026 Private Placement totaled $28,269. As the Series H Preferred Stock and Series H Warrants were classified in permanent equity, all transaction costs were recorded as an offset to additional paid-in capital.

​

February 2026 Omnibus Agreement

​

On February 24, 2026, the Company entered into the Omnibus Agreement, by and between the Company and January 2025 Investors, pursuant to which, the Company agreed to (i) repurchase from the January 2025 Investors $3,468 of aggregate principal amount of the Notes, representing the entire outstanding principal amounts of the Notes and any accrued and unpaid interest thereon, (ii) redeem 196 shares of Series G Preferred Stock held by the January 2025 Investors with an aggregate Stated Value of $196 and $27 of accrued and unpaid dividends thereon, representing all outstanding shares of Series G Preferred Stock, and (iii) redeem all Amended and Restated Warrants held by the January 2025 Investors, representing all outstanding Series A Warrants and Series B Warrants, for an aggregate cash purchase price of $9,000 (collectively, the “Repurchase”). The Repurchase closed on March 2, 2026.

​

On March 4, 2026, the Company filed a Certificate of Elimination (the “Certificate of Elimination”) with respect to its Series G Preferred Stock, with the Delaware Secretary of State. The Certificate of Elimination (i) eliminates the previous designation of 4,000 shares of Series G Preferred Stock, none of which were outstanding at the time of filing, (ii) causes such shares of Series G Preferred Stock to resume the status of authorized but unissued shares of preferred stock of the Company and (iii) eliminates all reference to the Series G Preferred Stock from the Company’s Amended and Restated Certificate of Incorporation, as amended.

​

The Company allocated the total cash purchase price related to the Repurchase among the Series G Preferred Stock, the Notes, and the Amended and Restated Warrants using the relative fair value method on March 2, 2026 as summarized in the table below and accounted for each instrument in accordance with the relevant accounting guidance:

​

​

Accounting Treatment – Redemption of Series G Preferred Stock

​

The following table summarizes the calculation of the net carrying value of the Series G Preferred Shares before the Repurchase:

​

​

During the three and six months ended June 30, 2026 the Company incurred $0 and $82 respectively, in dividends, and paid $0 and $76 of dividends in cash related to the Series G Preferred Stock. Additionally, during the six months ended June 30, 2026 the Company issued 1,855,442 shares of its common stock in conversion of Series G Preferred Shares for a total value of $543.

​

The Company estimated the $398 fair value of the remaining Series G Preferred Stock and the $22 fair value of the bifurcated embedded derivative related to the Series G Preferred Stock prior to the Repurchase on March 2, 2026 using a Monte Carlo simulation model, with the following inputs: the fair value of the Company’s common stock of $1.70 on the valuation date, estimated equity volatility of 148%, the time to maturity of 0.87 years, a discounted market interest rate 6.3%, a risk-free rate of 3.51%, dividend rate of 8.0%, a penalty dividend rate of 15.0%, and probability of default of 3.9%. Prior to the Repurchase, the Company recognized a gain of $0 and $40 related to the change in the fair value of the derivative during the three and six months ended June 30, 2026, respectively, which is recorded in change in fair value of derivative liabilities on the unaudited condensed consolidated statement of operations.

​

The Company treated the extinguishment of the Series G Convertible Preferred Stock as a redemption in accordance with ASC Topic 260, Earnings Per Share. Accordingly, the Company thus recognized a total of $106 representing the difference between the allocated consideration of $141 and the carrying amount of the Series G Preferred Shares of $247 as a deemed contribution, which is added to net loss attributable to common stockholders in the unaudited consolidated statement of operations and comprehensive loss for the six months ended June 30, 2026 and recognized as additional paid-in capital.

​

Accounting Treatment – Extinguishment of the Notes

​

The following table summarizes the calculation of the net carrying value of the Notes before the Repurchase:

​

​

The Company recognized interest expense totaling approximately $0 and $53 during the three and six months ended June 30, 2026 prior to the Repurchase, reflecting an effective interest rate of 8.80% and which was comprised of approximately $46 interest at the stated rate, and approximately $7 representing the amortization of the premium recognized at issuance.

​

The Company estimated the $12,906 fair value of the Notes and the $9,431 fair value of the bifurcated embedded derivative related to the Notes prior to the Repurchase on March 2, 2026 using a Monte Carlo simulation model, with the following inputs: the fair value of the Company’s common stock of $1.70 on the valuation date, estimated equity volatility of 108%, the time to maturity of 3.03 years, a discounted market interest rate of 6.5%, a risk-free rate of 3.43%, and probability of default of 15.6%. Prior to the Repurchase, the Company recognized a loss of $5,624 related to the change in the fair value of the derivative during the three and six months ended June 30, 2026, which is recorded in change in fair value of derivative liabilities on the unaudited condensed consolidated statement of operations.

​

The Company accounted for the repurchase of the Notes as a debt extinguishment in accordance with ASC Topic 470, Debt. Accordingly, the $8,527 difference between the allocated consideration of $4,583 and the carrying amount of the Notes of $13,109 was recognized as a capital contribution recognized in additional paid-in capital as the Notes were held by certain of the Company’s investors.

​

Accounting Treatment – Repurchase of the Amended and Restated Warrants

​

The Company estimated the $12,044 fair value of the Amended and Restated Warrants prior to the Repurchase on March 2, 2026 using the Black Scholes Model using the following weighted average assumptions: the fair value of the Company’s common stock per share of $1.70; remaining term of 3.87 years; equity volatility of 103%; and a risk-free interest rate of 3.49%.

​

The Company accounted for the repurchase of the Amended and Restated Warrants in accordance with the guidance in ASC Topic 815, Derivatives and Hedging, related to the repurchase of freestanding equity-classified instruments. Accordingly, the allocated consideration of $4,277 was recorded as reduction of additional paid-in capital.
