Stock Warrants	Note 13: Stock Warrants 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, 56,410 shares of the Company’s common stock (the “Shares”) and (ii) in a concurrent private placement, the Company issued to the Purchaser Class A common warrants to purchase an aggregate of up to 56,410 shares of its common stock (the “A Warrants”) at an exercise price of $36.30 per share and Class B common warrants to purchase an aggregate of up to 56,410 shares of its common stock (the “B Warrants” and, along with the A Warrants, the “Common Warrants”) at an exercise price of $36.30 per share. On September 30, 2024, the Company entered into a Purchase Agreement with the Purchaser in the May 2024 Securities Purchase Agreement as Purchaser, pursuant to which the Company issued to the Purchaser, (i) in a registered direct offering, 46,530 shares of its common stock (“Shares”) and (ii) in the concurrent Private Placement, Class C and Class D Warrants, each to purchase an aggregate of up to 46,530 Shares (the “Common Warrant Shares”) each with an exercise price of $28.00. The Class C and Class D Warrants together, hereinafter the “Common Warrants”. The purchase price for Shares in the registered direct offering was $28.00 per Share. On July 30, 2025, the Company announced closing a public offering of an aggregate of 2,000,000 shares of its common stock (or pre-funded warrants in lieu thereof), Class E warrants to purchase up to 2,000,000 shares of common stock, and Class F warrants to purchase up to 2,000,000 shares of common stock, at a combined public offering price of $4.00 per share (or $3.999 per pre-funded warrant) and accompanying warrants. The warrants had an exercise price of $4.00 per share and were exercisable immediately upon issuance. The Class E warrants will expire on the fifth anniversary of the original issuance date, and the Class F warrants will expire on the eighteen-month anniversary of the original issuance date. Gross proceeds, before deducting placement agent fees and offering expenses, were $8 million. Maxim Group LLC acted as sole placement agent in connection with this offering. Based on a review of the Class E and F Warrants, it was determined that the warrants met the liability criteria which resulted in Class E & F warrants to be treated as liability under ASC 815 – Derivatives and Hedging. Accordingly, a loss was recognized and the resulting computed value was classified as a liability on the Company’s balance sheet at December 31, 2025. On December 30, 2025, the Company declared a stock dividend of one share of common stock for every 1,000 shares of outstanding common stock as well as one share of common stock for every outstanding option or warrant that has a right to receive stock dividends (“Alternate Securities”). On January 13, 2026, the Company distributed a dividend of one share of its common stock for every 1,000 shares of common stock issued and outstanding as of January 9, 2026, as well as one share of common stock for every outstanding option or warrant that has a right to receive stock dividends (the “Dividend”). The issuance of the Dividend was a Share Combination Event under Section 3(g) of the Class E & F Common Stock Purchase Warrants. As a result, the number of outstanding warrants of Class E & F Common Stock Purchase Warrants both increased to 5,561,125 and the exercise price was reduced to $1.439 per share of common stock. Due to the Share Combination Event trigger of the Class E & F Common Stock Purchase Warrants, the warrants were reevaluated, resulting in the reclassification of the warrants from liability to equity. The Company recognized a loss on the fair market valuation of the warrants of $468 thousand in the statements of operations for the six months ended June 30, 2026, and reclassified the Class E & F Common Stock Purchase Warrants from liability to equity in the amount of $8.7 million reflected in the Balance Sheet at June 30, 2026. On March 6, 2026, the Company completed a rights offering (the “2026 Rights Offering”) to our stockholders and to holders of certain of our outstanding options and warrants that had the right to participate in the 2026 Rights Offering as of February 10, 2026, the record date. In the Rights Offering the Company issued non-transferable subscription rights to purchase 1,842 Units. Each Unit consists of one share of Series G Convertible Preferred Stock (the “G Preferred”) and 2,000 warrants to purchase common stock (the “G Warrants”). Each share of G Preferred is convertible, at the option of the holder at any time, into a number of shares of our common stock equal to the quotient of the stated value of the Preferred Stock ($1 thousand) divided by $1.00, the conversion price. Each G Warrant is exercisable for one share of our common stock at an exercise price of $1.00 per share from March 6, 2026, the date of issuance, through its expiration five years from the date of issuance. The 2026 Rights Offering raised $1.8 million in gross proceeds.

The Existing May 2024 Warrants had an exercise price of $36.30 per share, the Existing September 2024 Warrants had an exercise price of $28.00, and the Existing July 2025 Warrants had an exercise price of $1.439. Pursuant to the Inducement Letter, the Holders agreed to exercise the Existing Warrants for cash at a reduced exercise price of $0.48 per share in consideration of the Company’s agreement to issue the Holders new warrants to purchase up to a number of shares of Common Stock equal to 200% of the number of shares of Common Stock issued pursuant to such Holder’s exercise of Existing Warrants, comprised of new Class H warrants to purchase up to 17,439,856 shares of Common Stock (the “Inducement Warrants” and the shares of Common Stock underlying the Inducement Warrants, the “Inducement Warrant Shares”) with an exercise term of 5 years from the initial exercise date. The initial exercise date of the Inducement Warrants is the Stockholder Approval Date, and the exercise price thereof is $0.60 per share.

The Company also issued to the Placement Agent warrants to purchase up to 6.0% of the aggregate number of shares of Common Stock issued upon exercise of the Existing Warrants pursuant to the Inducement Letter. The Placement Agent Warrants have substantially the same terms as the Inducement Warrants, except that the Placement Agent Warrants will be exercisable until the five-year anniversary of the date of issuance, will have an exercise price equal to 125% of the Reduced Exercise Price, and will include piggyback registration rights that are triggered if there is not an effective registration statement covering all of the Placement Agent Warrant Shares while the Placement Agent Warrants are outstanding. On May 21, 2026, the Company issued and sold 7,519,351 shares of common stock, par value $0.001 per share, and, in a concurrent private placement, Class I warrants to purchase up to 15,038,702 shares of common stock to certain investors for aggregate gross proceeds of approximately $2.4 million. On June 10, 2026, the Company issued and sold 2,554,119 shares of common stock and, in a concurrent private placement, 771,503 shares of common stock, pre-funded warrants to purchase up to 1,782,616 shares of common stock, and Class J warrants to purchase up to 10,216,476 shares of common stock to certain investors for aggregate gross proceeds of approximately $2.6 million. 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.
