Registered Direct Offerings and Private Placements

On November 10, 2025, the Company entered into a securities purchase agreement (the “November 2025 Securities Purchase Agreement”) pursuant to which the Company agreed to sell and issue to a single investor in a registered direct offering (the “November Registered Direct Offering”): (i) 1,970,000 shares of common stock, par value $0.00001 per share (the “common stock”), at an offering price of $1.68 per share, and (ii) pre-funded warrants (the “November Pre-Funded Warrants”) to purchase up to 1,601,429 shares of common stock at an offering price of $1.67999 per November Pre-Funded Warrant. Each November Pre-Funded Warrant is exercisable for one share of common stock. The November Pre-Funded Warrants have an exercise price of $0.00001 per share, are immediately exercisable, and may be exercised at any time until exercised in full.

​

Also pursuant to the November Securities Purchase Agreement, in a concurrent private placement offering (the “November PIPE Offering,” and collectively with the Registered Direct Offering, the “November Offering”), the Company agreed to sell and issue to the Investor detachable Series A common stock Purchase Warrants (the “Series A Warrants”) to purchase up to 3,571,429 shares of common stock and detachable Series B common stock Purchase Warrants (the “Series B Warrants,” and collectively with the Series A Warrants (the “November Common Warrants”) to purchase up to 3,571,429 shares of common stock. The Series A Warrants will be exercisable beginning six months from the date of issuance at an exercise price of $1.75 per share, and will expire two years from the date of issuance. The Series B Warrants will be exercisable beginning six months from the date of issuance at an exercise price of $2.00 per share, and will expire five and one-half years from the date of issuance. The November Common Warrants meet the criteria for equity classification.

​

The Company generated gross proceeds of $6,000,000 and net proceeds of approximately $5,404,000 from the November Offering after deducting under writing discounts and commissions and other offering expenses. Additionally, on November 25, 2025 the November Pre-Funded Warrants were exercised, the Company received $16.01, the par value of the shares issued, and the Company issued 1,601,429 of the Company’s $0.00001 par value common shares.

​

On December 15, 2025, the Company filed a Prospectus registering the common shares underlying Series A and B Common Warrants. The filing of the Preliminary Prospectus enables the registered shares of common stock to be issued upon the exercise of the November Common Warrants.

​

The exercise price of the November Pre-Funded and November Common Warrants are subject to adjustment in the case of customary events such as stock dividends or other distributions on shares of common stock or any other equity or equity equivalent securities payable in shares of common stock, stock splits, stock combinations, reclassifications or similar events affecting the Common Stock, and also, subject to limitations, upon any distribution of assets, including cash, stock or other property to our stockholders.

The November Common Warrants grant certain participation rights to the warrant holder. If the Company issues rights, warrants, or other purchase rights to common stockholders on a pro rata basis, the warrant holder can participate as if it already exercised the warrant in full. If the company declares any distribution to common stock holders, including, cash dividends stock dividends, spin-offs, property distributions, reorganizations or similar transactions, then the holder participates as if it held all warrant shares immediately before the record date. In the event of a fundamental transaction the holder can, generally, exercise the warrant, and receive the same consideration received by the common shareholders. These participation rights may be held in abeyance, or limited if they result in the holder exceeding beneficial ownership limitations as defined in the warrants.

On May 15, 2026, the Company entered into a securities purchase agreement (the “May Securities Purchase Agreement”) pursuant to which the Company agreed to sell and issue to a single investor in a registered direct offering (the “May Registered Direct Offering”): (i) 1,133,334 shares of common stock par value $0.00001per share, (ii) Pre-funded warrants (the “May Pre-Funded Warrants”) to purchase up to 200,000 shares of common stock, at an offering price of $1.49999 per May Pre-Funded Warrant, and (iii) accompanying common warrants to purchase up to 1,333,334 shares of common stock (“May Common Warrants”). Each May Pre-Funded Warrant is exercisable for one share of common stock. The May Pre-Funded Warrants have an exercise price of $0.00001 per share, are immediately exercisable, and may be exercised at any time until exercised in full. The May Common Warrants will be exercisable beginning six

months from the date of issuance at an exercise price of $1.75 per share, and will expire three years from the date of issuance. The May Common Warrants meet the criteria for equity classification.

​

On May 18, 2026, the Company generated gross proceeds of $2,000,000 and net proceeds of approximately $1,703,000 from the May Offering after deducting under writing discounts and commissions and other offering expenses. The May Pre-Funded Warrants were exercised, the Company received $2.00, the par value of the shares issued, and the Company issued 200,000 of the Company’s $0.00001 par value common shares.

​

On June 15, 2026, the Company filed a Preliminary Prospectus registering the common shares underlying May Common Warrants. The filing of the Preliminary Prospectus enables the registered shares of common stock to be issued upon the exercise of the May Common Warrants.

​

The exercise price of the May Pre-Funded and May Common Warrants are subject to adjustment in the case of customary events such as stock dividends or other distributions on shares of common stock or any other equity or equity equivalent securities payable in shares of common stock, stock splits, stock combinations, reclassifications or similar events affecting the common stock, and also, subject to limitations, upon any distribution of assets, including cash, stock or other property to our stockholders.

The May Common Warrants grant certain participation rights to the warrant holder. If the Company issues rights, warrants, or other purchase rights to common stockholders on a pro rata basis, the warrant holder can participate as if it already exercised the warrant in full. If the company declares any distribution to common stockholders, including, cash dividends stock dividends, spin-offs, property distributions, reorganizations or similar transactions, then the holder participates as if it held all warrant shares immediately before the record date. In the event of a fundamental transaction the holder can, generally, exercise the warrant, and receive the same consideration received by the common shareholders. These participation rights may be held in abeyance, or limited if they result in the holder exceeding beneficial ownership limitations as defined in the warrants.
