**Item 1.01 Entry into a Material Definitive Agreement.**

On March 13, 2026, ParkerVision, Inc., a Florida corporation (the "<u>Company</u>") entered into exchange agreements (each an "Exchange Agreement" and collectively, the "Exchange Agreements") with certain holders (the "Holders") of the Company's outstanding convertible promissory notes (the "Exchange Notes").

Pursuant to the Exchange Agreements, the Holders agreed to exchange the outstanding principal amount of the Exchange Notes held by them, together with accrued and unpaid interest thereon through the closing date of the exchange, for shares of the Company's common stock, par value $0.01 per share (the "Common Stock") at an exchange price of $0.21 per share (the "Exchange Price").

The exchanges were effected pursuant to Section 3(a)(9) of the Securities Act of 1933, as amended (the "Securities Act"), which provides an exemption from registration for securities exchanged by the issuer with its existing security holders exclusively where no commission or other remuneration is paid or given directly or indirectly for soliciting such exchange.

In connection with the exchanges, the Company issued an aggregate of 3,277,099 shares of Common Stock to the Holders in exchange for the cancellation of Exchange Notes having an aggregate outstanding principal amount of $675,000 and accrued and unpaid interest of approximately $13,200.

Upon completion of the exchanges, the Exchange Notes surrendered by the Holders were cancelled and extinguished and are no longer outstanding.

The Exchange Agreements contain customary representations and warranties of the parties and provide that the Exchange Shares are being issued pursuant to the exemption from registration provided by Section 3(a)(9) of the Securities Act. The foregoing description of the Exchange Agreements does not purport to be complete and is qualified in its entirety by reference to the form of Exchange Agreement, which is filed as Exhibit 10.1 to this Current Report on Form 8-K and incorporated herein by reference.

**Item 3.02 Unregistered Sales of Equity Securities.**

The information set forth in Item 1.01 of this Current Report on Form 8-K is incorporated herein by reference.

On March 13, 2026, the Company issued an aggregate of 3,277,099 shares of its Common Stock to the Holders in exchange for the cancellation of Exchange Notes having an aggregate outstanding principal amount of $675,000 and accrued and unpaid interest of approximately $13,200.

The shares of Common Stock issued in the exchanges (the "Exchange Shares") were issued in reliance upon the exemption from registration provided by Section 3(a)(9) of the Securities Act. The Exchange Shares were issued solely to existing holders of the Exchange Notes and no commission or other remuneration was paid or given directly or indirectly for soliciting the exchanges.
