This prospectus supplement amends and supplements the ATM Prospectus dated June 9, 2025, relating to the offer and sale of common stock under the Sales Agreement with Cantor Fitzgerald & Co. and Craig-Hallum Capital Group LLC. The initial offering amount was reduced from $300,000,000 to $150,000,000 due to changes in the company's strategy.
As of September 30, 2025, the company has already sold 3,936,578 shares for gross proceeds of $22,997,761 under the Sales Agreement. The common stock is listed on NYSE American under the symbol "KULR," with the last reported sale price being $4.22 per share on September 29, 2025.
Sales will be conducted as "at the market offerings" under Rule 415(a)(4) of the Securities Act of 1933, with Cantor and Craig-Hallum acting as sales agents without committing to sell any specific amount. The Sales Agents will receive a commission of up to 3.0% of the gross sales price per share sold.
Significant risks associated with the business and investment are detailed in the "Risk Factors" section of the ATM Prospectus. Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities.
