**PROSPECTUS SUPPLEMENT SUMMARY**

This summary contains basic information about us and our business but does not contain all of the information that is important to your investment decision. You should read this summary together with the more detailed information contained elsewhere in this prospectus supplement and the accompanying base prospectus and the documents incorporated herein and therein by reference before making an investment decision. Investors should carefully consider the information set forth under the caption "Risk Factors" appearing elsewhere in this prospectus supplement, including those described in documents incorporated by reference herein.

Unless otherwise indicated, references to "we," "us," "our," "ParkerVision" or the "Company" refer to ParkerVision, Inc. Additionally, references to the "Board" refer to the board of directors of ParkerVision, Inc.

**Our Company**

We were incorporated under the laws of the state of Florida on August 22, 1989. We have designed and developed proprietary radio frequency ("RF") technologies and integrated circuits based on those technologies and we license our technologies to others for use in wireless communication products. We have expended significant financial and other resources to research and develop our RF technologies and to obtain patent protection for those technologies in the United States of America ("U.S.") and certain foreign jurisdictions. We believe certain patents protecting our proprietary technologies have been broadly infringed by others and therefore the primary focus of our business plan is the enforcement of our intellectual property rights through patent infringement litigation and licensing efforts. We currently have patent enforcement actions ongoing in various U.S. district courts against mobile handset providers and providers of smart televisions and other WiFi products and, in certain cases, their chip suppliers for the infringement of several of our RF patents. We have made significant investments in developing and protecting our technologies, the returns on which are dependent upon the generation of future revenues for realization.

Our business address is 4446-1A Hendricks Avenue, Suite 354, Jacksonville, Florida 32207 and our telephone number is (904) 732-6100. We maintain a website at www.parkervision.com.

Factors that might cause actual results to differ from teh results discussed in the forward-looking statements include those discussed in "Our Company," "Risk Factors," and elsewhere in this prospectus and any prospectus supplements and any free writing prospectus.

**RISK FACTORS**

An investment in our securities involves a high degree of risk. Before deciding whether to invest in our securities, you should carefully consider the risk factors described below and in the accompanying base prospectus, together with other information in this prospectus supplement, the accompanying base prospectus, and the information incorporated by reference herein and therein as set forth in our filings with the SEC, including our most recent Annual Report on Form 10-K for the year ended December 31, 2024, and any subsequent Quarterly Reports on Form 10-Q or Current Reports on Form 8-K. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also affect our business and results of operations. If any of these risks actually occur, our business, financial conditions or results of operations could be seriously harmed. In that event, the market price for our common stock could decline and you may lose all or part of your investment.

**Risks Related to this Offering**

***Our management will have broad discretion in the use of the net proceeds from this offering and may spend the proceeds in ways with which you may not agree and in ways that may not increase the value of your investment.***

Our management will have broad discretion in the application of the net proceeds from this offering, and our stockholders will not have the opportunity as part of their investment decision to assess whether the net proceeds are being used appropriately. Because of the number and variability of factors that will determine our use of the net proceeds from this offering, their ultimate use may vary substantially from their currently intended use. The failure by our management to apply these funds effectively could harm our business. See "*Use of Proceeds*" on page S-5 of this prospectus supplement for a description of our proposed use of proceeds from this offering.

***You will experience immediate and substantial dilution in the net tangible book value per share of the common stock you purchase.***

The price per share of our common stock offered hereby is substantially higher than the net tangible book value per share of our common stock. As a result, investors purchasing shares of our common stock in this offering will incur immediate dilution of approximately $0.53 per share, after giving effect to the sale of all 16,481,579 shares of our common stock offered hereby at a public offering price of $0.21 per share, and the deduction of the estimated offering expenses payable by us. See "*Dilution*" on page S-7 of this prospectus supplement for a more detailed discussion of the dilution you will incur if you purchase shares in this offering.

***We will require additional capital funding, the receipt of which may impair the value of our common stock.***

Our future capital requirements depend on many factors, including the timing of and necessary investment in our patent licensing and enforcement program. We may need to raise additional capital through public or private equity or debt offerings or through arrangements with strategic partners or other sources for the continuation of our business plan. There can be no assurance that additional capital will be available when needed or on terms satisfactory to us, if at all. To the extent we raise additional capital by issuing equity securities, our stockholders may experience substantial dilution and the new equity securities may have greater rights, preferences or privileges than our existing common stock

***Only a limited market exists for our common stock which could lead to price volatility.***

Our common stock trades on the OTCQB Venture Market and the trading volume for our common stock has been low. The limited trading market for our common stock may cause fluctuations in the market value of our common stock to be exaggerated, leading to price volatility in excess of that which would occur in a more active trading market for our common stock.

[**Table of Contents**](#toc)

**USE OF PROCEEDS**

We received proceeds of $3,461,132 from this offering, before deducting offering expenses payable by us.

We intend to use the net proceeds from this offering for general corporate purposes, including, as needed, litigation fees and expenses.

The foregoing table does not take into account our convertible securities, warrants, stock options, or restricted stock awards as set forth in footnote (2) in "*Prospectus Summary - The Offering*."

[**Table of Contents**](#toc)

**DILUTION**

If you invest in our shares, your ownership interest will be diluted to the extent of the differences between the price you paid per share of common stock in this offering and the net tangible book value per share of our common stock after this offering. Net tangible book value per share represents total tangible assets less total liabilities, divided by the number of shares of our common stock outstanding.

Our historical actual net tangible book value as of September 30, 2025 was approximately $(50,562), or approximately $(0.42) per share of our common stock issued and outstanding as of September 30, 2025. The negative net tangible book value results primarily from our accumulated deficit.

After giving effect to the issuance of an aggregate of 5,941,243 shares of our common stock and receipt of estimated net proceeds of $1,128,000, between October 1, 2025 and November 21, 2025, as set forth in footnote (1) in "*Prospectus Summary - The Offering",* our estimated and unaudited "as adjusted" net tangible book value was approximately $(49,385), or approximately $(0.39) per share of our common stock issued and outstanding as of November 21, 2025.

Our unaudited pro forma as adjusted net tangible book value is approximately $(45,944), or $(0.32) per share of our common stock after giving further effect to the sale by us of all 16,481,579 shares of our common stock offered hereby at an offering price of $0.21 per share, and the deduction of the estimated offering expenses payable by us. This represents an immediate increase in net tangible book value of $0.07 per share to existing shareholders and an immediate dilution of $0.53 per share to the Investors purchasing shares in this offering.

The following table illustrates the dilution on a per share basis for investors purchasing shares in this offering:

---

| | | |
|:---|:---|:---|
| Public offering price per share in this offering |  | $0.21 |
| &nbsp;&nbsp;&nbsp;&nbsp;Pro forma net tangible book value per share as of September 30, 2025, as adjusted | $(0.39) |  |
| &nbsp;&nbsp;&nbsp;&nbsp;Increase in net tangible book value attributable to this offering | $0.07 |  |
| Pro forma as adjusted net tangible book value per share as of September 30, 2025 | $(0.32) |  |
| Dilution per share to new investors in this offering |  | $0.53 |

---

The per share calculations above are based on the following number of shares of our common stock issued and outstanding at September 30, 2025: 120,394,060 shares on a historical actual basis, 126,335,303 shares on an unaudited "as adjusted" basis*,* and 142,816,882 shares on an unaudited pro forma as adjusted basis, each as described above.

The foregoing table does not take into account our convertible securities, warrants, stock options, or restricted stock awards as set forth in footnote (2) in "*Prospectus Summary - The Offering*."

**$25,000,000** 

**Common Stock**

**Warrants**

We may offer and sell, from time to time, shares of our common stock, par value $0.01 per share ("Common Stock"), warrants, or any combination thereof, in one or more offerings in amounts, at prices and on terms that we determine at the time of the offering, with an aggregate initial offering price of up to $25,000,000.

This prospectus describes the general terms of these securities and the general manner in which these securities may be offered. We will provide you with the specific terms of any offering in one or more supplements to this prospectus. The prospectus supplements will also describe the specific manner in which these securities will be offered and may also supplement, update or amend information contained in this document. You should read this base prospectus and any prospectus supplement, as well as any documents incorporated by reference into this base prospectus, or any prospectus supplement, carefully before you invest.

Our securities may be sold directly by us to you, through agents designated from time to time, or through underwriters or dealers. For additional information on the methods of sale, you should refer to the section entitled "Plan of Distribution" in this base prospectus and in the applicable prospectus supplement. If any underwriters or agents are involved in the sale of our securities with respect to which this base prospectus is being delivered, the names of such underwriters or agents and any applicable fees, commissions or discounts and over-allotment options will be set forth in a prospectus supplement. The price to the public of such securities and the net proceeds that we expect to receive from such sale will also be set forth in a prospectus supplement.

Pursuant to General Instruction I.B.6 of Form S-3, in no event will we sell our securities in public primary offerings with a value exceeding more than one-third of our public float in any 12-month period so long as our public float remains below $75.0 million. As of May 16, 2025 the aggregate market value of our outstanding common stock held by non-affiliates, or the public float, was approximately $53,786,641 based on 112,055,502 shares of our outstanding Common Stock that were held by non-affiliates on such date and a price of $0.48 per share, which was the last sale price of our Common Stock on the OTCQB Venture Market on May 16, 2025, calculated in accordance with General Instruction I.B.6 of Form S-3. We have not offered any securities pursuant to General Instruction I.B.6 of Form S-3 during the twelve-month period that ends on and includes the date hereof.

**ABOUT THIS PROSPECTUS**

This prospectus is part of a registration statement that we filed with the Securities and Exchange Commission, (the "SEC"), using a "shelf" registration process. Under this shelf registration process, we may offer and sell from time to time any combination of the securities described in this prospectus in one or more offerings in amounts, at prices and on terms that we determine at the time of the offering, with an aggregate offering price of up to $xx. This prospectus provides you with a general description of the securities we may offer.

Each time we offer securities, we will provide a prospectus supplement that describes the terms of the relevant offering. The prospectus supplement also may add, update or change information contained in this prospectus. We may also authorize one or more free writing prospectuses to be provided to you that may contain material information relating to these offerings. The prospectus supplement or free writing prospectus may also add, update or change information contained in this prospectus with respect to that offering. If there is any inconsistency between the information in this prospectus and the applicable prospectus supplement or free writing prospectus, you should rely on the prospectus supplement or free writing prospectus, as applicable. Before purchasing any securities, you should carefully read both this prospectus and the applicable prospectus supplement (and any applicable free writing prospectuses), together with the additional information described under the headings "Where You Can Find More Information" and "Incorporation by Reference."

We have not authorized anyone to provide you with any information or to make any representations other than those contained in this prospectus, any applicable prospectus supplement or any free writing prospectuses prepared by or on behalf of us or to which we have referred you.

**CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS**

This prospectus and the documents incorporated by reference herein contain forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the Securities Act) and Section 21E of the Securities Exchange Act of 1934, as amended (the Exchange Act). All statements other than statements of historical facts contained in this prospectus and the documents incorporated by reference herein, are forward looking statements. These forward-looking statements include statements about our plans, objectives, expectations, intentions and assumptions, and all other statements that are not statements of historical fact. Words such as "may," "will," should," "estimates," "plans," "expects," "believes," "intends" and similar expressions may identify forward-looking statements, but the absence of such words does not mean that a statement is not forward-looking. We cannot guarantee future results, levels of activity, performance or achievements. Our actual results and the timing of certain events may differ significantly from the results discussed in the forward-looking statements. Factors that might cause such a discrepancy include those discussed in "Our Company," "Risk Factors," and elsewhere in this prospectus and any prospectus supplements and any free writing prospectus. You are cautioned not to place undue reliance on any forward-looking statements. Except as required by applicable law, we do not plan to publicly update or revise any forward-looking statements contained in this prospectus or the documents incorporated by reference herein, whether as a result of any new information, future events, changed circumstances or otherwise. For all forward-looking statements, we claim the protection of the safe harbor for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995.

**SUMMARY**

*This summary highlights selected information contained elsewhere, or incorporated by reference, in this prospectus. This summary does not contain all of the information that you should consider before deciding to invest in our securities. You should carefully read the entire prospectus, any accompanying prospectus supplement and any related free writing prospectus, including the risks of investing in our securities discussed under the heading* "*Risk Factors*" *contained herein and in any accompanying prospectus supplement and any related free writing prospectus, and under a similar heading in other documents that are incorporated by reference into this prospectus. You also should carefully read the information incorporated by reference into this prospectus, including our financial statements and the exhibits to the registration statement of which this prospectus is a part.*

**Our Company**

We were incorporated under the laws of the state of Florida on August 22, 1989. We have designed and developed proprietary radio frequency ("RF") technologies and integrated circuits based on those technologies and we license our technologies to others for use in wireless communication products. We have expended significant financial and other resources to research and develop our RF technologies and to obtain patent protection for those technologies in the United States of America ("U.S.") and certain foreign jurisdictions. We believe certain patents protecting our proprietary technologies have been broadly infringed by others and therefore the primary focus of our business plan is the enforcement of our intellectual property rights through patent infringement litigation and licensing efforts. We currently have patent enforcement actions ongoing in various U.S. district courts against mobile handset providers and providers of smart televisions and other WiFi products and, in certain cases, their chip suppliers for the infringement of several of our RF patents. We have made significant investments in developing and protecting our technologies, the returns on which are dependent upon the generation of future revenues for realization.

Our business address is 4446-1A Hendricks Avenue, Suite 354, Jacksonville, Florida 32207 and our telephone number is (904) 732-6100. We maintain a website at www.parkervision.com.

**RISK FACTORS**

Investment in any securities offered pursuant to this prospectus and the applicable prospectus supplement involves risks. Before deciding whether to invest in our securities, you should carefully consider the risk factors incorporated by reference to our most recent Annual Report on Form 10-K and any subsequent Quarterly Reports on Form 10-Q or Current Reports on Form 8-K, and all other information contained in or incorporated by reference into this prospectus, as updated by our subsequent filings under the Exchange Act, and the risk factors and other information contained in the applicable prospectus supplement and any applicable free writing prospectus. The occurrence of any of these risks might cause you to lose all or part of your investment in the offered securities. There may be other unknown or unpredictable economic, business, competitive, regulatory or other factors that could have material adverse effects on our future results. Past financial performance may not be a reliable indicator of future performance, and historical trends should not be used to anticipate results or trends in future periods. If any of these risks actually occurs, our business, financial condition, results of operations or cash flow could be seriously harmed. This could cause the trading price of our securities to decline, resulting in a loss of all or part of your investment. Please also carefully read the section entitled "Cautionary Note Regarding "Forward-Looking Statements" included above.

**USE OF PROCEEDS**

We will retain broad discretion over the use of the net proceeds from the sale of the securities offered hereby. Except as described in any prospectus supplement or any related free writing prospectus that we may authorize to be provided to you, we currently intend to use the net proceeds from the sale of the securities offered hereby for general corporate purposes, including litigation expenses. We may also use a portion of the net proceeds to acquire or invest in businesses and products that are complementary to our own, although we have no current plans, commitments or agreements with respect to any acquisitions as of the date of this prospectus. We will set forth in the applicable prospectus supplement or free writing prospectus our intended use for the net proceeds received from the sale of any securities sold pursuant to the prospectus supplement or free writing prospectus. We intend to invest the net proceeds to us from the sale of securities offered hereby that are not used as described above in short-term, investment-grade, interest-bearing instruments.

------

[**Table of Contents**](#toc)

**PLAN OF DISTRIBUTION**

We may sell any or all of the securities covered by this prospectus directly to purchasers or through underwriters, broker-dealers, or agents, who may receive compensation in the form of discounts, concessions, or commissions from us. These discounts, concessions, or commissions as to any particular underwriter, broker-dealer, or agent may be in excess of those customary in the types of transactions involved.

The securities may be sold in one or more transactions at fixed prices, at prevailing market price at the time of sale, at varying prices determined at the time of sale, or at negotiated prices. These sales may be effected in transactions which may involve crosses or block transactions.

If underwriters are used in an offering of securities, such offered securities may be resold in one or more transactions:

● on any national securities exchange or quotation service on which the common stock may be listed or quoted at the time of sale, including, as of the date of this prospectus, the Nasdaq Capital Market in the case of the common stock;

● in the over-the-counter market;

● in transactions otherwise than on these exchanges or services or in the over-the-counter market; or

● through the writing of options, whether the options are listed on an options exchange or otherwise.

Each prospectus supplement will state the terms of the offering, including, but not limited to:

● the names of any underwriters, dealers, or agents;

● the public offering or purchase price of the securities and the net proceeds that we will receive from the sale;

● any underwriting discounts and commissions or other items constituting underwriters' compensation;

● any discounts, commissions, or fees allowed or paid to dealers or agents; and

● any securities exchange on which the offered securities may be listed.

If we sell securities to underwriters, we will execute an underwriting agreement with them at the time of the sale and will name them in the applicable prospectus supplement. In connection with these sales, the underwriters may be deemed to have received compensation in the form of underwriting discounts and commissions. The underwriters also may receive commissions from purchasers of securities for whom they may act as agent. Unless we specify otherwise in the applicable prospectus supplement, the underwriters will not be obligated to purchase the securities unless the conditions set forth in the underwriting agreement are satisfied, and if the underwriters purchase any of the securities offered by such prospectus supplement, they will be required to purchase all of such offered securities. The underwriters may acquire the securities for their own account and may resell the securities from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or varying prices determined at the time of sale. The underwriters may sell the securities to or through dealers, and those dealers may receive discounts, concessions, or commissions from the underwriters as well as from the purchasers for whom they may act as agent.

We may designate agents who agree to use their reasonable efforts to solicit purchasers for the period of their appointment or to sell securities on a continuing basis. We may also sell securities directly to one or more purchasers without using underwriters or agents.

Under agreements entered into with us, underwriters and agents may be entitled to indemnification by us against certain civil liabilities, including liabilities under the Securities Act, or to contribution for payments the underwriters or agents may be required to make. The underwriters, agents, and their affiliates may engage in financial or other business transactions with us and our subsidiaries in the ordinary course of business.

The aggregate proceeds to us from the sale of the securities will be the purchase price of the securities less discounts and commissions, if any.

In order to facilitate the offering of the securities, any underwriters may engage in transactions that stabilize, maintain, or otherwise affect the price of the securities or any other securities the prices of which may be used to determine payments on such securities. Specifically, any underwriters may over allot in connection with the offering, creating a short position for their own accounts. In addition, to cover overallotments or to stabilize the price of the securities or of any such other securities, the underwriters may bid for, and purchase, the securities or any such other securities in the open market. Finally, in any offering of the securities through a syndicate of underwriters, the underwriting syndicate may reclaim selling concessions allowed to an underwriter or a dealer for distributing the securities in the offering if the syndicate repurchases previously distributed securities in transactions to cover syndicate short positions, in stabilization transactions, or otherwise. Any of these activities may stabilize or maintain the market price of the securities above independent market levels. Any such underwriters are not required to engage in these activities and may end any of these activities at any time.

The applicable prospectus supplement may provide that the original issue date for your securities may be more than three scheduled business days after the trade date for your securities. Accordingly, in such a case, if you wish to trade securities on any date prior to the third business day before the original issue date for your securities, you will be required, by virtue of the fact that your securities initially are expected to settle in more than three scheduled business days after the trade date for your securities, to make alternative settlement arrangements to prevent a failed settlement.

The securities may be new issues of securities and may have no established trading market. The securities may or may not be listed on a national securities exchange. We can make no assurance as to the liquidity of or the existence of trading markets for any of the securities.

In order to comply with the securities laws of some states, if applicable, the shares of common stock offered by this prospectus must be sold in such jurisdictions only through registered or licensed brokers or dealers. In addition, in some states the shares of common stock may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with.

To the extent required, this prospectus may be amended or supplemented from time to time to describe a specific plan of distribution.

**DESCRIPTION OF SECURITIES**

The following description of our capital stock is a summary only and is qualified by reference to our Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws, which are included herewith as Exhibits 3.1 through 3.11, respectively.

**Common Stock**

We are authorized to issue up to 225,000,000 shares of Common Stock, $0.01 par value per share. As of May 16, 2025, there were 119,519,494 shares of our Common Stock outstanding. Holders of our Common Stock are entitled to one vote per share on all matters submitted to a vote of shareholders and may not cumulate votes for the election of directors. Common shareholders have the right to receive dividends when, as, and if declared by the Board from funds legally available therefore. Holders of Common Stock have no preemptive rights and have no rights to convert their Common Stock into any other securities.

**Classified Board; Director Nominations; Special Meetings**

Our Board is divided into three classes, with only one class of directors elected at each annual meeting, and our shareholders may remove our directors only for cause. Nominations for our Board may be made by our Board or by any holder of Common Stock. A shareholder entitled to vote for the election of directors may nominate a person for election as director only if the shareholder provides written notice of his nomination to our secretary not later than 120 days in advance of the same day and month that our proxy statement was released to shareholders in connection with the previous year's annual meeting of shareholders or, if no annual meeting was held in the previous year, then by the end of the fiscal year to which the annual meeting in which the nomination will be made relates. A special meeting of our shareholders may be called only by our Board or our chief executive officer. These provisions and the Board's right to issue shares of our preferred stock from time to time, in one or more classes or series without shareholder approval, are intended to enhance the likelihood of continuity and stability in the composition of the policies formulated by our Board. These provisions are also intended to discourage some tactics that may be used in proxy fights.

**Description of Warrants**

Set forth below is a description of the general terms and conditions of the warrants that may be offered under this prospectus. The specific terms and conditions of the warrants will be described in a supplement to this prospectus. Any prospectus supplement may add, change, update, or supersede the terms and conditions of the warrants as described in this prospectus. To the extent the information contained in the prospectus supplement differs from the summary set forth below, you should rely on the information in the prospectus supplement. The summary below and in the prospectus supplement do not contain all of the information that you may find useful or that may be important to you. You should refer to the provisions of the warrant agreement and warrant certificate because those documents, and not the summaries, define your rights as a holder of the warrants.

***General***

We may issue warrants for the purchase of our Common Stock. Warrants may be issued independently or together with any of our Common Stock offered by a prospectus supplement, and may be attached to or separate from those offered securities. A copy of the form of any such warrant agreement, will be filed with the SEC in connection with the offering of particular warrants.

***Terms of Warrants***

The prospectus supplement relating to a particular issue of warrants to purchase our Common Stock will describe the terms of those warrants, which may include, without limitation, one or more of the following:

● the title or designation of the warrants;

● the aggregate number of the warrants;

● the price or prices at which the warrants will be issued;

● the price at which the underlying securities purchasable upon exercise of the warrants may be purchased;

● the date on which the right to exercise the warrants shall commence and the date on which such right shall expire;

● if applicable, the minimum or maximum amount of the warrants that may be exercised at any one time;

● if applicable, the date on and after which the warrants and the related underlying securities will be separately transferable;

● information with respect to book-entry procedures, if any; and

● any other terms of the warrants, including terms, procedures, and limitations relating to the exercise of the warrants.

***Exercise of Warrants***

Each warrant will entitle the holder of the warrant to purchase at the exercise price set forth in the applicable prospectus supplement the number of shares of Common Stock being offered. Holders may exercise warrants at any time up to the close of business on the expiration date set forth in the applicable prospectus supplement. After the close of business on the expiration date, unexercised warrants will be void. Holders may exercise warrants as described in the prospectus supplement relating to the warrants being offered. Until a holder exercises the warrants to purchase shares of our Common Stock , the holder will not have any rights as a holder of shares of our Common Stock by virtue of ownership of the warrants.

**INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE**

**DISCLOSURE OF COMMISSION POSITION ON INDEMNIFICATION**

**FOR SECURITIES ACT LIABILITY**

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling the registrant pursuant to the foregoing provisions, the registrant has been informed that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable.
