Item 1.01. Entry Into a Material Definitive Agreement

On February 18, 2026, the Company entered into subscription agreements with a group of private accredited investors, which included family members of a director of the Company, as well as the owner of a licensee of the Company licensed to produce SPD-SmartGlass products including SPD-SmartGlass products for the retrofit architectural glass market.

The investors purchased 1.1 million shares of common stock of the Company at a price of $1.00 per share (which represents the closing market price of the Company’s common stock on February 13, 2026 which was the date that the transaction was agreed to). The Company will receive $1.1 million in proceeds from the sale of common stock to the investors. For each share received, the investor also received one warrant (expiring on February 28, 2031) to purchase one share of common stock at an exercise price of $1.10 for warrant exercises occurring on or before February 28, 2027, $1.20 for warrant exercises occurring between March 1, 2027 through February 29, 2028, $1.30 for warrant exercises occurring between March 1, 2028 through February 28, 2029, and $1.50 for warrant exercises occurring after February 28, 2029 and prior to the expiration of the warrants.

The shares were issued to the investors in a private placement and, along with the shares issued in connection with the exercise of any warrants in the future, are not registered and therefore currently subject to at least a six month holding period by the investor. Research Frontiers is filing the related transaction documents as Exhibits 1.1 and 1.2 to this current report on Form 8-K.
