PARKERVISION, INC.

1,578,946 Shares of Common Stock

This Prospectus Supplement relates to the prospectus dated January 24, 2022, as amended and supplemented from time to time (the “Prospectus”), which permits the resale by the selling stockholder listed in the Prospectus of up to 1,578,946 shares of our common stock, par value $0.01 per share (“Common Stock”) consisting of an aggregate of 1,052,631 shares of Common Stock and 526,315 shares of Common Stock underlying warrants (“Warrants”) issued pursuant to a securities purchase agreement dated December 14, 2021.

We will not receive proceeds from the sale of the shares of Common Stock by the selling stockholder. To the extent the Warrants are exercised for cash, we will receive up to an aggregate of $526,315 in gross proceeds. We expect to use the proceeds received from the exercise of the Warrants, if any, for general working capital purposes, including payment of litigation expenses.

This Prospectus Supplement is being filed to update and supplement the information previously included in the Prospectus with the information contained in our Current Report on Form 8-K filed with the Securities and Exchange Commission (the “SEC”) on June 7, 2024. Accordingly, we have attached the 8-K to this prospectus supplement. You should read this prospectus supplement together with the prospectus, which is to be delivered with this prospectus supplement.

Any statement contained in the Prospectus shall be deemed to be modified or superseded to the extent that information in this Prospectus Supplement modifies or supersedes such statement. Any statement that is modified or superseded shall not be deemed to constitute a part of the Prospectus except as modified or superseded by this Prospectus Supplement.

This Prospectus Supplement should be read in conjunction with, and may not be delivered or utilized without, the Prospectus.

Our Common Stock is listed on the OTCQB Venture Capital Market under the ticker symbol “PRKR.”

Investing in our securities involves a high degree of risk. See “Risk Factors” beginning on page 5 of the Prospectus for a discussion of information that should be considered in connection with an investment in our securities.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved these securities or determined whether this Prospectus or Prospectus Supplement is truthful or complete. Any representation to the contrary is a criminal offense.

The date of this prospectus supplement is June 7, 2024.
