Item 8.01. Other Events.

As previously disclosed, on May 16, 2024, Ascent Solar Technologies, Inc., a Delaware corporation (“we,” “us,” the “Company” or “Ascent”), entered into an At The Market Offering Agreement (the “ATM Agreement”) with H.C. Wainwright & Co., LLC, as sales agent (“Wainwright”), to sell shares of its common stock, par value $0.0001 per share (the “Shares”), with an aggregate sales price of initially up to $4,219,000, from time to time, through an “at the market offering” program.

As previously disclosed, pursuant to prospectus supplements dated May 23, 2024 and May 30, 2024, to our shelf registration statement on Form S-3 (File No. 333-267971) initially filed by the Company with the U.S. Securities and Exchange Commission (the “SEC”) on October 21, 2022, and declared effective by the SEC on November 7, 2022 (the “Registration Statement”), the Company increased the amount available for sale under the ATM Agreement, up to an additional aggregate offering price of $4,344,000 and $3,981,000 of Shares, respectively.

The Company has determined to increase the amount available for sale under the ATM Agreement, up to an additional aggregate offering price of $758,818 of Shares. The Shares will be issued pursuant to our Registration Statement and the related prospectus supplement (the “Prospectus Supplement”), dated August 20, 2025.

Because there is no minimum offering amount required pursuant to the ATM Agreement, the total number of Shares to be sold under the ATM agreement, if any, and proceeds to the Company, if any, are not determinable at this time. The Company expects to use any net proceeds primarily for general and administrative expenses and other general corporate purposes. The Company’s management will have significant discretion and flexibility in applying the net proceeds from the sale of these securities.

This Current Report does not constitute an offer to sell or the solicitation of an offer to buy any security nor shall there be any sale of these securities in any state in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state.

Attached hereto as Exhibit 5.1, and incorporated by reference to the Prospectus Supplement, is the opinion of Carroll Legal LLC relating to the legality of the issuance and sale of the Shares.

Since May 16, 2024, the Company has sold 1,537,783 shares of common stock under the ATM Agreement for gross proceeds of approximately $11,883,824.54. The Company’s current outstanding shares of common stock are 3,047,658 as of August 20, 2025.
