Preliminary Prospectus,

Subject to Completion, dated June 25, 2025

ASCENT SOLAR TECHNOLOGIES, INC.

UP TO 3,205,129 SHARES OF COMMON STOCK

AND 3,205,129 ACCOMPANYING WARRANTS TO PURCHASE UP TO 3,205,129 SHARES OF COMMON STOCK

OR

UP TO 3,205,129 PRE-FUNDED WARRANTS TO PURCHASE UP TO 3,205,129 SHARES OF COMMON STOCK

AND ACCOMPANYING WARRANTS TO PURCHASE UP TO 3,205,129 SHARES OF COMMON STOCK

UP TO 224,359 PLACEMENT AGENT WARRANTS TO PURCHASE UP TO 224,359 SHARES OF COMMON STOCK

UP TO 6,634,617 SHARES OF COMMON STOCK ISSUABLE UPON EXERCISE OF THE WARRANTS, PRE-FUNDED WARRANTS AND PLACEMENT AGENT WARRANTS

We are offering up to 3,205,129 shares of common stock, par value $0.0001 per share (the “Common Stock”), together with warrants to purchase up to 3,205,129 shares of common stock (the “Warrants”), pursuant to this prospectus. The assumed combined public offering price for each share of Common Stock, together with an accompanying Warrant to purchase one (1) share of Common Stock, is $1.56, which is equal to the last reported sale price of our Common Stock on The Nasdaq Capital Market on June 23, 2025. The shares of Common Stock and accompanying Warrants will be separately issued, but the shares of Common Stock and accompanying Warrants will be issued to purchasers in the ratio of one-for-one (1 for 1). Each Warrant will have an exercise price of $1.56 per share, will be exercisable beginning on the effective date of stockholder approval of the issuance of the shares upon exercise of the Warrants (the “Warrant Stockholder Approval”), provided however, if the Pricing Conditions (as defined below) are met, the Warrant Stockholder Approval will not be required and the Warrants will be exercisable upon issuance (the “Initial Exercise Date”). The Warrants will expire on the five (5) year anniversary of the Initial Exercise Date or the effective date of the Warrant Stockholder Approval, as applicable. As used herein “Pricing Conditions” means that the combined public offering price per share and accompanying Warrant is such that the Warrant Stockholder Approval is not required under the rules of The Nasdaq Stock Market LLC (“Nasdaq”) because either (i) the offering is an at-the-market offering under Nasdaq rules and such price equals or exceeds the sum of (a) the applicable “Minimum Price” per share under Nasdaq Rule 5635(d) plus (b) $0.125 per whole share of Common Stock underlying the Warrants or (ii) the offering is a discounted offering where the pricing and discount (including attributing a value of $0.125 per whole share of Common Stock underlying the Warrants) meet the pricing requirements under Nasdaq’s rules.

We are also offering up to 3,205,129 pre-funded warrants (the “Pre-Funded Warrants”) to those purchasers whose purchase of shares of Common Stock in this offering would result in the purchaser, together with its affiliates and certain related parties, beneficially owning more than 4.99% (or, at the election of the purchaser, 9.99%) of our outstanding Common Stock following the consummation of this offering in lieu of the shares of our Common Stock that would result in ownership in excess of 4.99% (or, at the election of the purchaser, 9.99%). Each Pre-Funded Warrant will be exercisable for one (1) share of Common Stock at an exercise price of $0.0001 per share. Each Pre-Funded Warrant is being issued together with the same Warrants described above being issued with each share of Common Stock. The assumed combined public offering price for each such Pre-Funded Warrant, together with an accompanying Warrant to purchase one (1) share of Common Stock, is $1.5599, which is equal to the last reported sale price of our Common Stock on The Nasdaq Capital Market on June 23, 2025, minus $0.0001, the exercise price of the Pre-Funded Warrants. Each Pre-Funded Warrant will be exercisable upon issuance and may be exercised at any time until all of the Pre-Funded Warrants are exercised in full. The Pre-Funded Warrants and accompanying Warrants are immediately separable and will be issued separately in this offering, but the Pre-Funded Warrants and Warrants will be issued to purchasers in the ratio of one-for-one (1 for 1). This prospectus also relates to the offering of the shares of Common Stock issuable upon exercise of the Warrants, Pre-Funded Warrants and Placement Agent Warrants (as defined herein). For each Pre-Funded Warrant sold, the number of shares of Common Stock sold will be reduced on a one-for-one basis.

There is no established public trading market for the Warrants or the Pre-Funded Warrants, and we do not expect a market to develop. We do not intend to apply for listing of the Warrants or the Pre-Funded Warrants on any securities exchange or other nationally recognized trading system. Without an active trading market, the liquidity of the Warrants and the Pre-Funded Warrants will be limited.

This offering will terminate on July 31, 2025, unless we decide to terminate the offering (which we may do at any time in our discretion) prior to that date. We will have one closing for all the securities purchased in this offering. The combined public offering price per share of Common Stock (or Pre-Funded Warrant in lieu thereof) and accompanying Warrant will be fixed for the duration of this offering.

We have engaged H.C. Wainwright & Co., LLC (the “Placement Agent”), to act as our exclusive placement agent in connection with this offering. The Placement Agent has agreed to use its reasonable best efforts to arrange for the sale of the securities offered by this prospectus. The Placement Agent is not purchasing or selling any of the securities we are offering and the Placement Agent is not required to arrange the purchase or sale of any specific number of securities or dollar amount. We have agreed to pay to the Placement Agent the Placement Agent fees set forth in the table below, which assumes that we sell all of the securities offered by this prospectus. There is no minimum number of securities or amount of proceeds required as a condition to closing in this offering. In addition, because there is no escrow trust or similar arrangement and no minimum offering amount, investors could be in a position where they have invested in our company, but we are unable to fulfill all of our contemplated objectives due to a lack of interest in this offering. Investors in this offering will not receive a refund in the event that we do not sell an amount of securities sufficient to pursue our business goals described in this prospectus. Further, any proceeds from the sale of securities offered by us will be available for our immediate use, despite uncertainty about whether we would be able to use such funds to effectively implement our business plan. We will bear all costs associated with the offering. See “Plan of Distribution” on page 23 of this prospectus for more information regarding these arrangements.

Our Common Stock is traded on the Nasdaq Capital Market under the symbol “ASTI.” On June 23, 2025, the closing price for our Common Stock, as reported on the Nasdaq Capital Market, was $1.56 per share.

The assumed combined offering price used throughout this prospectus has been included for illustration purposes only, and may not be indicative of the final offering price. The actual combined public offering price per share of Common Stock and accompanying Warrant and the combined public offering price per Pre-Funded Warrant and accompanying Warrant we are offering and the exercise price and other terms of the Warrants will be negotiated between us and the purchasers, in consultation with the Placement Agent based on the trading of our Common Stock prior to this offering, among other factors. Other factors considered in determining the offering price of the securities we are offering and the exercise price and other terms of the Warrants include the history and prospects of our company, the stage of development of our business, our business plans for the future and the extent to which they have been implemented, an assessment of our management, general conditions of the securities markets at the time of the offering and such other factors as were deemed relevant. The combined public offering price per share of Common Stock and accompanying Warrant and the combined public offering price per Pre-Funded Warrant and accompanying Warrant may be at a discount to the current market price of our Common Stock. Therefore, the recent market price used throughout this prospectus may differ substantially from the combined public offering price.

You should read this prospectus, together with additional information described under the headings “Information Incorporated by Reference” and “Where You Can Find More Information” carefully before you invest in any of our securities.

We are a “smaller reporting company” as defined under the federal securities laws and, as such, have elected to be subject to reduced public company reporting requirements. See “Prospectus Summary- Smaller Reporting Company Status.”

(1) Represents a cash fee equal to 7.0% of the aggregate gross proceeds raised in this offering. In addition, we have also agreed to pay the Placement Agent a management fee equal to 1.0% of the aggregate gross proceeds raised in this offering and to reimburse the Placement Agent for its non-accountable expenses in the amount of $15,000, for its legal fees and expenses and other out-of-pocket expenses in an amount of up to $100,000, and for its clearing expenses in the amount of $15,950. In addition, we have agreed to issue to the Placement Agent, or its designees, warrants (the “Placement Agent Warrants”) as compensation in connection with this offering to purchase a number of shares of our Common Stock equal to 7.0% of the aggregate number of shares of Common Stock and Pre-Funded Warrants being offered at an exercise price equal to 125% of the combined public offering price per share of Common Stock and accompanying Warrant. See the section entitled “Plan of Distribution” of this prospectus for a description of the compensation to be received by the Placement Agent.

(2) Because there is no minimum number of securities or amount of proceeds required as a condition to closing in this offering, the actual offering amount, Placement Agent fees, estimated expenses and net proceeds to us, if any, are not presently determinable and may be substantially less than the total maximum offering amounts set forth above. The amount of the proceeds to us presented in this table does not give effect to any exercise of the Warrants or Placement Agent Warrants offered hereby.

We anticipate that delivery of the securities against payment will be made on or about , 2025, subject to the satisfaction of customary closing conditions.

Investing in our securities involves a high degree of risk. Before buying any shares, you should carefully read the discussion of material risks of investing in our securities in “Risk Factors” beginning on page 8 of this prospectus.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or passed on the adequacy or accuracy of this prospectus. Any representation to the contrary is a criminal offense.
