Rhea-AI Filing Summary

ParkerVision, Inc. is registering 16,809,295 shares of its common stock for resale by the selling stockholders under a Prospectus Supplement dated March 23, 2026. The resale pool includes shares issuable on conversion of notes, shares issued under purchase agreements and as consideration, and shares issuable upon exercise of warrants.

The company states it will not receive proceeds from sales by the selling stockholders; however, if the Aspire and Tailwinds warrants are exercised for cash, the company would receive up to $3,900,000. Shares outstanding were 147,535,024 as of March 19, 2026.

Insights

Resale registration preserves secondary liquidity without immediate capital inflow for the issuer.

The filing registers 16,809,295 shares for resale by selling holders and explicitly states the company will not receive proceeds from those resale transactions. The issuer could receive up to $3,900,000 only if specified warrants are exercised for cash.

Cash-flow treatment is clear: resale proceeds go to selling holders; any potential cash inflow to the company depends solely on warrant exercises. Subsequent filings or closing notices will specify whether holders sell through the registration or whether warrants are exercised.

The company remains litigation-centric with contingent financings shaping future cash flow allocation.

ParkerVision's Annual Report discloses significant ongoing patent enforcement activity and substantial contingent payment obligations recorded at an estimated fair value of $46.1M as of Dec 31, 2025. The company estimates that initial future proceeds may be heavily allocated to repay contingent financings.

The resale registration lists convertible-note-related shares and warrants among the resale sources; any monetization from litigation or license settlements will be subject to existing contingent repayment priorities. Monitor litigation milestones and settlement receipts in subsequent filings for material impact.

INTRODUCTORY NOTE

Unless the context otherwise requires, in this Annual Report on Form 10-K (“Annual Report”), “we”, “us”, “our” and the “Company” mean ParkerVision, Inc.

Forward-Looking Statements

We believe that it is important to communicate our future expectations to our shareholders and to the public. This Annual Report contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, including, without limitation, statements about our future plans, objectives, and expectations under the headings “Item 1. Business” and “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.” Forward-looking statements include any statement that does not directly relate to any historical or current fact. When used in this Annual Report and in future filings by the Company with the Securities and Exchange Commission (“SEC”), the words or phrases “will likely result”, “management expects”, “we expect”, “will continue”, “is anticipated”, “estimated” or similar expressions are intended to identify such “forward-looking statements.” Readers are cautioned not to place undue reliance on such forward-looking statements, each of which speaks only as of the date made. Such statements are subject to certain risks and uncertainties that could cause actual results to differ materially from historical results and those presently anticipated or projected, including the risks and uncertainties set forth in this Annual Report under the heading “Item 1A. Risk Factors” and in our other periodic reports. Examples of such risks and uncertainties include general economic and business conditions, the outcome of litigation, unexpected changes in technologies and technological advances, reliance on our intellectual property, and the ability to obtain adequate financing in the future. We have no obligation to publicly release the results of any revisions that may be made to any forward-looking statements to reflect anticipated events or circumstances occurring after the date of such statements.

PART I

Item 1. Business.

We are in the business of innovating and licensing our fundamental wireless technologies. 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 current business plan is the enforcement of our intellectual property rights through licensing efforts and patent infringement litigation efforts. We have determined that our business currently operates under a single operating and reportable segment.

We currently have five licensees of our technologies, all of which resulted from our patent enforcement efforts. We currently have patent enforcement actions ongoing in various U.S. district courts against mobile handset, smart television and other WiFi product providers, as well as semiconductor 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.

Table of Contents

We spent the majority of 2025 supporting our current patent enforcement actions, including the defense of Inter Partes Review ("IPR") actions filed against us. We currently have nine patent enforcement actions pending in the Western District of Texas against five separate foreign defendants and one domestic defendant. Two such cases were scheduled for trial in March 2026 and April 2026, respectively, although the March 2026 case was postponed just prior to commencing in March 2026. Six of the pending actions, against five separate defendants, are currently stayed pending results from other related actions, including IPRs. In addition, we have a patent enforcement action against Qualcomm that has been granted an expedited appeal by the Court of Appeals for the Federal Circuit ("CAFC"). The Qualcomm case was subject to a prior appeal filed by us in 2022, for which we received a favorable opinion and a remand of the case back to the district court for the Middle District of Florida in 2024. We have an additional patent enforcement action against Qualcomm and Apple in the Middle District of Florida and against LG in the District of New Jersey, both of which are currently stayed pending the outcome of the current pending case against Qualcomm. A number of defendants in our patent enforcement actions have filed petitions for IPR against claims of the asserted patents. Currently, we have IPRs that have been instituted by the Patent Trial and Appeal Board ("PTAB") against claims on four of our asserted patents, including one IPR that is currently pending director review following an unfavorable PTAB decision. In addition, in late 2024, we filed a petition with the U.S. Supreme Court with respect to two unfavorable PTAB decisions that were upheld by the CAFC through Rule 36 decisions in 2024. Our petition was denied by the Supreme Court on March 24, 2025.

See “Legal Proceedings” in Note 12 to our consolidated financial statements included in Item 8 for a detailed description of our various patent enforcement actions. A significant portion of our litigation costs have been funded under a secured contingent payment arrangement with Brickell Key Investments, LP (“Brickell”), contingent arrangements with legal counsel, and various debt and equity financings. See Note 9 to our consolidated financial statements included in Item 8 and “Liquidity and Capital Resources” included in Item 7 for a full discussion of our litigation funding arrangements and our equity and debt financings.

Products and Licenses

Since 2019, we have focused predominantly on our patent enforcement and licensing efforts. As of December 31, 2025, we had five licensees for our technologies. All of our license agreements resulted from settlement of patent enforcement actions initiated by us. To date, our patent license and settlement agreements have included a one-time, up-front payment to cover past and future use of our technologies, with no future recurring revenue. See “Revenue” in Note 3 to our consolidated financial statements included in Item 8 for additional details.

RF Technologies

Our RF technologies enable highly accurate transmission and reception of RF carriers at low power consumption, thereby enabling extended battery life, and certain size, cost, performance, and packaging advantages. We believe the most significant hurdle to the licensing and/or sale of our technologies and related products is the widespread use of certain of our technologies in infringing products produced by companies with significantly greater financial, technical, sales, and marketing resources. We believe we can secure licensing agreements with unauthorized current users of one or more of our technologies based on a solid and defensible patent portfolio and the advantages enabled by our unique patent-protected technologies.

Patents and Trademarks

We consider our intellectual property, including patents, patent applications, trademarks, and trade secrets to be significant to our business plan. We have a program to file applications for and obtain patents, copyrights, and trademarks in the U.S. and in selected foreign countries where we believe filing for such protection is appropriate to establish and maintain our proprietary rights in our technology and products. As of December 31, 2025, we had approximately 36 active U.S. and foreign patents related to our RF technologies. In addition, we have over 70 patents that have expired over the past eight years that we believe continue to have significant economic value as a result of our ability to assert past damages in our patent enforcement actions. We estimate the economic lives of our patents to be the shorter of fifteen years from issuance or twenty years from the earliest application date. Our current portfolio of issued patents have expiration dates ranging from 2026 to 2036.

Table of Contents

Employees

As of December 31, 2025, we had seven full-time employees and one part-time employee. We also outsource certain specialty services, such as information technology ("IT") and public relations, and utilize contract staff and third-party consultants from time to time to supplement our workforce. Our employees are not represented by any collective bargaining agreements and we consider our employee relations to be satisfactory.

Following the COVID-19 pandemic, we reverted to fully remote worksites for all of our employees. Our management, with the oversight of our Board of Directors ("Board"), monitors the hiring, retention, and management of our employees.

Item 1A. Risk Factors.

In addition to other risks and uncertainties described in this Annual Report, the following risk factors should be carefully considered in evaluating our business because such factors may have a significant impact on our business, operating results, liquidity and financial condition. As a result of the risk factors set forth below, actual results could differ materially from those projected in any forward-looking statements.

Table of Contents

Financial and Operating Risks

Our financial condition raises substantial doubt as to our ability to continue as a going concern.

We have had significant losses and negative cash flows in nearly every year since inception, and continue to have an accumulated deficit which, at December 31, 2025, was approximately $455.6 million. Our net loss for the years ended December 31, 2025 and 2024 was approximately $7.4 million and $14.5 million, respectively. Our independent registered public accounting firm has included in their audit opinion on our consolidated financial statements as of and for the year ended December 31, 2025, a statement with respect to substantial doubt about our ability to continue as a going concern. Note 2 to our consolidated financial statements included in Item 8 includes a discussion regarding our liquidity and our ability to continue as a going concern. Our consolidated financial statements have been prepared assuming we will continue to operate as a going concern, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. If we become unable to continue as a going concern, we may have to liquidate our assets and the values we receive for our assets in liquidation or dissolution could be significantly lower than the values reflected in our consolidated financial statements. The substantial doubt as to our ability to continue as a going concern may adversely affect our ability to negotiate reasonable terms with our vendors and may adversely affect our ability to raise additional capital in the future.

We have had a history of losses which may ultimately compromise our ability to implement our business plan and continue in operation.

With the exception of the year ended December 31, 2023, our technologies and products have not produced revenues sufficient to cover our operating costs. We will continue to make expenditures on patent protection and enforcement and general operations in order to continue our current patent enforcement and licensing efforts. Those efforts may not produce a successful financial outcome in 2026, or at all. Without a successful financial outcome from one or more of our patent enforcement and licensing efforts, we will not achieve profitability. If we are not able to generate sufficient revenues or obtain sufficient capital resources, we may not be able to implement our business plan or meet our current obligations due within the twelve months after the issuance date of our consolidated financial statements and investors will suffer a loss in their investment. This may also result in a change in our business strategies.

We will need to raise substantial additional capital in the future to fund our operations. Failure to raise such additional capital may prevent us from implementing our business plan as currently formulated.

Because we have a history of net losses and negative cash flow from operations, we have funded our operating costs primarily from the sale of debt and equity securities, including our secured and unsecured contingent debt obligations. Our current capital resources include cash and cash equivalents of $4.4 million at December 31, 2025, which will not alone be sufficient to meet our working capital needs for the twelve months following the issuance of our consolidated financial statements. Our business plan will continue to require expenditures for patent protection and enforcement and general operations. If we do not generate sufficient revenues from our licensing and patent enforcement programs, we will require additional capital to fund our operations. Additional capital may be in the form of debt securities, the sale of equity securities, including common or preferred stock, additional litigation funding, or a combination thereof. Failure to raise additional capital may have a material adverse impact on our ability to achieve our business objectives.

Table of Contents

Raising additional capital by issuing debt securities or additional equity securities may result in dilution and/or impose covenants or restrictions that create operational limitations or other obligations.

We may require additional capital to fund our operations and meet our current obligations due within the twelve months after the issuance date of our consolidated financial statements. Financing, if any, may be in the form of debt or sales of equity securities, including common or preferred stock. Debt instruments or the sale of preferred stock may result in the imposition of operational limitations and other covenants and payment obligations, any of which may be burdensome to us and may have a material adverse impact on our ability to implement our business plan as currently formulated. The sale of equity securities, including common or preferred stock, may result in dilution to the current shareholders’ ownership and may be limited by the number of shares we have authorized and available for issuance.

We may be obligated to repay outstanding notes at a premium upon the occurrence of an event of default.

We have $3.1 million in outstanding principal under convertible notes at December 31, 2025. If we fail to comply with the various covenants set forth in each of the notes, including failure to pay principal or interest when due or consummating a change in control, we could be in default thereunder. Upon an event of default under each of the notes, the interest rate of the notes will increase to 12% per annum and the outstanding principal balance of the notes plus all accrued unpaid interest may be declared immediately payable by the holders. We may not have sufficient available funds to repay the notes upon an event of default, and we cannot provide assurances that we will be able to obtain other financing at terms acceptable to us, or at all.

Our ability to utilize our tax benefits could be substantially limited if we fail to generate sufficient income or if we experience an “ownership change.”

We have cumulative net operating loss carryforwards (“NOLs”) totaling approximately $254.7 million at December 31, 2025, of which $203.9 million is subject to expiration in varying amounts from 2026 to 2037. Our ability to fully recognize the benefits from those NOLs is dependent upon our ability to generate sufficient income prior to their expiration. In addition, our NOL carryforwards may be limited if we experience an ownership change as defined by Section 382 of the Internal Revenue Code (“Section 382”). In general, an ownership change under Section 382 occurs if one or more 5% shareholders increase their collective ownership of the aggregate amount of our outstanding shares by more than 50 percentage points over a relevant lookback period. We have sold a significant number of equity securities over the relevant lookback period which increases the risk of triggering an ownership change under Section 382 from the future sale of additional equity securities. An ownership change under Section 382 will significantly limit our ability to utilize our tax benefits.

Our litigation funding arrangements may impair our ability to obtain future financing and/or generate sufficient cash flows to support our future operations.

We have funded much of our cost of litigation through contingent financing arrangements with Brickell and others and contingent fee arrangements with legal counsel. The repayment obligation to Brickell is secured by the majority of our assets. Furthermore, our contingent arrangements will result in reductions in the amount of net proceeds retained by us from litigation, licensing, and other patent-related activities. The contingent fees payable to legal counsel, Brickell and others will consume all of our initial future proceeds up to specified limits and will likely exceed half of our proceeds thereafter depending on size and timing of proceeds, among other factors. The long-term continuation of our business plan is dependent upon our ability to secure sufficient financing to support our business, and our ability to generate revenues and/or patent related proceeds sufficient to offset expenses and meet our contingent payment obligations. Failure to generate revenue or other patent-related proceeds sufficient to repay our contingent obligations may impede our ability to obtain additional financing which will have a material adverse effect on our ability to achieve our long-term business objectives.

Table of Contents

Our litigation can be time-consuming, costly and we cannot anticipate the results.

Since 2011, we have spent a significant amount of our financial and management resources to pursue patent infringement litigation against third parties. We believe this litigation will continue to consume management and financial resources for long periods of time. There can be no assurance that our litigation matters will ultimately result in a favorable outcome for us or that our financial resources will not be exhausted before achieving a favorable outcome. In addition, even if we obtain favorable interim rulings or verdicts in particular litigation matters, they may not be predictive of the ultimate resolution of the matter. Unfavorable outcomes could result in exhaustion of our financial resources and could hinder our ability to pursue licensing and/or product opportunities for our technologies in the future. Failure to achieve favorable outcomes from one or more of our patent enforcement actions will have a material adverse impact on our financial condition, results of operations, cash flows, and business prospects.

If our patents and intellectual property rights do not provide us with the anticipated market protections, our competitive position, business, and prospects will be impaired.

We rely on our intellectual property rights, including patents and patent applications, to provide competitive advantage and protect us from theft of our intellectual property. We believe that our patents are for entirely new technologies and that our patents are valid, enforceable, and valuable. However, third parties have made claims of invalidity with respect to certain of our patents and other similar claims may be brought in the future. For example, the PTAB has issued a number of rulings invalidating claims of certain of our patents as a result of third-party challenges filed by defendants in our patent enforcement actions. If our patents are shown not to be as broad as currently believed or are otherwise challenged such that some or all of the protection is lost, we will suffer adverse effects from the loss of competitive advantage and our ability to offer unique products and technologies. As a result, there would be an adverse impact on our financial condition and business prospects. Furthermore, defending against challenges to our patents may give rise to material costs for defense and divert resources away from our other activities.

Our business, results of operations, and financial condition may be impacted by risks related to pandemics and other similar outbreaks.

The COVID-19 pandemic created significant volatility and uncertainty in financial markets and negatively impacted the timing of our current patent enforcement actions as a result of travel restrictions, office closures and court closures. Future pandemics or other similar outbreaks could likewise adversely impact our business, results of operations and financial condition. For example, market volatility and uncertainty could impact our ability to raise additional capital on terms that are acceptable to us, or at all. Additionally, business shut-downs, court closures, and travel restrictions resulting from future outbreaks could cause material delays in our patent enforcement and licensing program which is currently our sole source of revenue. The extent to which future pandemics or similar outbreaks impact our ongoing business strategy, as well as our results of operations and financial condition, generally, will depend on future developments which are highly uncertain and cannot be predicted, including the severity and duration of the outbreak and the actions taken by governments and private businesses to contain or treat its impact, among others. If the disruptions posed by future pandemics or outbreaks continue for an extensive period of time, our business, results of operations, and financial condition may be materially adversely affected.

Table of Contents

We are subject to outside influences beyond our control, including new legislation that could adversely affect our licensing and enforcement activities and have an adverse impact on the execution of our business plan.

Our licensing and enforcement activities are subject to numerous risks from outside influences, including new legislation, regulations and rules related to obtaining or enforcing patents. For instance, over the past decade, the U.S. has enacted sweeping changes to the U.S. patent system including changes that transition the U.S. from a “first-to-invent” to a “first-to-file” system and other changes that alter the processes for challenging issued patents. To the extent that we are unable to secure patent protection for our future technologies and/or our current patents are challenged such that some or all of our protection is lost, we will suffer adverse effects to our ability to offer unique products and technologies. As a result, there would be an adverse impact on our financial position, results of operations and cash flows and our ability to execute our business plan.

Our industry is subject to rapid technological changes which if we are unable to match or surpass, will result in a loss of competitive advantage and market opportunity.

Because of the rapid technological development that regularly occurs in the wireless technology industry, along with shifting user needs and the introduction of competing products and services, we have historically devoted substantial resources to developing and improving our technology and introducing new product offerings. As a result of our limited financial resources, we have ceased our research and development activities which could result in a loss of future market opportunity which could adversely affect our future revenue potential.

We are highly dependent on Mr. Jeffrey Parker as our chief executive officer. If his services were lost, it would have an adverse impact on the execution of our business plan.

Because of Mr. Parker’s leadership position in the Company, the relationships he has garnered in both the industry in which we operate and the investment community and the key role he plays in our patent litigation strategies, the loss of his services might be seen as an impediment to the execution of our business plan. If Mr. Parker was no longer available to the Company, investors might experience an adverse impact on their investment. We maintain a $1.5 million key-man life insurance policy on Mr. Parker.

If we are unable to retain key highly skilled employees, we will not be able to execute our current business plans.

Our business is dependent on having skilled and specialized key employees to conduct our business activities. The inability to retain these key employees would have an adverse impact on the technical support activities and the financial reporting and regulatory compliance activities that our business requires. These activities are instrumental to the successful execution of our business plan.

Any disruptions to our information technology systems or breaches of our network security could interrupt our operations, compromise our reputation, and expose us to litigation, government enforcement actions, and costly response measures and could have a material adverse effect on our business, financial condition, and results of operations.

We rely on information technology systems, including third-party hosted servers and cloud-based servers, to keep business, financial, and corporate records, communicate internally and externally, and operate other critical functions. If any of our internal systems or the systems of our third-party providers are compromised due to computer virus, unauthorized access, malware, and the like, then sensitive documents could be exposed or deleted, and our ability to conduct business could be impaired. Cyber incidents can result from deliberate attacks or unintentional events. These incidents can include, but are not limited to, unauthorized access to our systems, computer viruses or other malicious code, denial of service attacks, malware, ransomware, phishing, SQL injection attacks, human error, or other events that result in security breaches or give rise to the manipulation or loss of sensitive information or assets. Cyber incidents can be caused by various persons or groups, including disgruntled employees and vendors, activists, organized crime groups, and state-sponsored and individual hackers. Cyber incidents can also be caused or aggravated by natural events, such as earthquakes, floods, fires, power loss, and telecommunications failures. The risk of cybersecurity breach has generally increased as the number, intensity, and sophistication of attempted attacks from around the world has increased. While we have cyber security procedures in place, given the evolving nature of these threats, there can be no assurance that we will not suffer material losses in the future due to cyber-attacks.

To date, we have not experienced any material losses relating to cyber-attacks, computer viruses or other systems failures. Although we have taken steps to protect the security of data maintained in our information systems, it is possible that our security measures will not be able to prevent the systems’ improper functioning or the improper disclosure of personally identifiable information, such as in the event of cyber-attacks. In addition to operational and business consequences, if our cybersecurity is breached, we could be held liable to our customers or other parties in regulatory or other actions, and we may be exposed to reputation damages and loss of trust and business. This could result in costly investigations and litigation, civil or criminal penalties, fines, and negative publicity.

Risks Relating to our Common Stock

Our outstanding options and warrants may affect the market price and liquidity of the common stock.

At December 31, 2025, we had 143.2 million shares of common stock outstanding and had outstanding options, restricted share units, and warrants for the purchase of up to 29.3 million additional shares of common stock, the majority of which were exercisable as of December 31, 2025. In addition, as described more fully below, holders of convertible notes may elect to receive up to 24.7 million shares of common stock upon conversion of the notes, and we may elect to pay accrued interest on the notes in shares of our common stock. The majority of the shares of common stock underlying these securities are currently registered for sale to the holder or for public resale by the holder. The amount of common stock reserved for issuance may have an adverse impact on our ability to raise capital and may affect the price and liquidity of our common stock in the public market. In addition, the issuance of these shares of common stock will have a dilutive effect on current shareholders’ ownership.

Table of Contents

The conversion of outstanding convertible notes into shares of common stock, and the issuance of common stock by us as payment of accrued interest upon the convertible notes, could materially dilute our current shareholders.

We have an aggregate principal amount of $3.1 million in convertible notes outstanding at December 31, 2025. The notes are convertible into shares of our common stock at fixed conversion prices, which may be less than the market price of our common stock at the time of conversion. If the entire principal were converted into shares of common stock, we would be required to issue an aggregate of up to 24.7 million shares of common stock. If we issue all of these shares, the ownership of our current shareholders will be diluted.

Further, we may elect to pay interest on the notes, at our option, in shares of common stock, at a price equal to the then-market price for our common stock. From 2018 to 2025, we issued an aggregate of approximately 10.1 million shares of common stock as in-kind interest payments on our convertible notes. We currently do not believe that we will have the financial ability to make payments on the notes in cash when due. Accordingly, we currently intend to make such payments in shares of our common stock to the greatest extent possible. Such interest payments could further dilute our current shareholders.

The price of our common stock may be subject to substantial volatility.

The trading price of our common stock has been and may continue to be volatile. Between January 1, 2024 and March 1, 2026, the reported high and low sales prices for our common stock ranged between $0.09 and $1.18 per share. The price of our common stock may continue to be volatile as a result of a number of factors, some of which are beyond our control. These factors include, but are not limited to, developments in outstanding litigation, our performance and prospects, general conditions of the markets in which we compete, and other economic and financial conditions. Such volatility could materially and adversely affect the market price of our common stock in future periods.

Our common stock is quoted on OTCQB, an over-the-counter market. There can be no assurance that our common stock will continue to trade on the OTCQB or on another over-the-counter market or securities exchange.

Our common stock began trading on the OTCQB, an over-the-counter market, in August 2018 under the symbol “PRKR”. The over-the-counter market is a significantly more limited market than a nationally-recognized securities exchange such as Nasdaq, and the quotation of our common stock on the over-the-counter market has resulted in a less liquid market available for existing and potential shareholders to trade shares of our common stock. Securities traded in the over-the-counter market generally have less liquidity due to factors such as the reduced number of investors that will consider investing in the securities, the reduced number of market makers in the securities, and the reduced number of securities analysts that follow such securities. As a result, holders of shares of our common stock may find it difficult to resell their shares at prices quoted in the market or at all. We are also subject to additional compliance requirements under applicable state laws relating to the issuance of our securities. This could have a long-term adverse effect on our ability to raise capital, which ultimately could adversely affect the market price of our common stock. We cannot provide any assurances as to if or when we will be in a position to relist our common stock on a nationally-recognized securities exchange.

Table of Contents

Our common stock has been classified as a “penny stock” from time to time under SEC rules, which means broker-dealers who make a market in our stock may be subject to additional compliance requirements.

Our common stock has been deemed to be a "penny stock" in prior periods, as defined in the Securities Exchange Act of 1934 (the “Exchange Act”). Penny stocks are stocks (i) with a price of less than five dollars per share; (ii) that are not traded on a recognized national exchange; (iii) whose prices are not quoted on an automated quotation system sponsored by a recognized national securities association; or (iv) whose issuer has net tangible assets less than $2,000,000 (if the issuer has been in continuous operation for at least three years); or $5,000,000 (if continuous operations for less than three years); or with average revenues of less than $6,000,000 for the last three years. The Exchange Act requires broker-dealers dealing in penny stocks to provide potential investors with a document disclosing the risks of penny stocks and to obtain a manually signed and dated written receipt of the document before effecting any transaction in a penny stock for the investor’s account. Potential investors in our common stock are urged to obtain and read such disclosure carefully before purchasing any shares that are deemed to be “penny stock.” Further, the Exchange Act requires broker-dealers dealing in penny stocks to approve the account of any investor for transactions in such stocks before selling any penny stock to that investor. These procedures require the broker-dealer to (i) obtain from the investor information concerning his, her or its financial situation, investment experience and investment objectives; (ii) reasonably determine, based on that information, that transactions in penny stocks are suitable for the investor, and that the investor has sufficient knowledge and experience as to be reasonably capable of evaluating the risks of penny stock transactions; (iii) provide the investor with a written statement setting forth the basis on which the broker dealer made the determination in (ii) above; and (iv) receive a signed and dated copy of such statement from the investor, confirming that it accurately reflects the investor’s financial situation, investment experience and investment objectives. Although our stock is not currently classified as a penny stock, there can be no assurance that we will not revert to penny stock status in the future. Compliance with the penny stock requirements may affect the ability or willingness of broker-dealers to sell our securities, and accordingly would affect the ability of shareholders to sell their securities in the public market. These additional procedures could also limit our ability to raise additional capital in the future.

We do not currently pay dividends on our common stock and thus shareholders must look to appreciation of our common stock to realize a gain on their investments.

We do not currently pay dividends on our common stock and intend to retain our cash and future earnings, if any, to fund our business plan. Our future dividend policy is within the discretion of our Board and will depend upon various factors, including our business, financial condition, results of operations and capital requirements. We therefore cannot offer any assurance that our Board will determine to pay special or regular dividends in the future. Accordingly, unless our Board determines to pay dividends, shareholders will be required to look to appreciation of our common stock to realize a gain on their investment. There can be no assurance that this appreciation will occur.

Provisions in our certificate of incorporation and by-laws could have effects that conflict with the interest of shareholders.

Some provisions in our certificate of incorporation and by-laws could make it more difficult for a third party to acquire control of us. For example, our Board is divided into three classes with directors having staggered terms of office, our Board has the ability to issue preferred stock without shareholder approval, and there are advance notification provisions for director nominations and submissions of proposals from shareholders to a vote by all the shareholders under the by-laws. Florida law also has anti-takeover provisions in its corporate statute.

Item 1C. Cybersecurity.

For purposes of the following disclosure, the terms "cybersecurity incident" and "cybersecurity threat" have the meanings given to such terms in Item 106(a) of Regulation S-K promulgated under the Securities Exchange Act of 1934.

Given the small size of our organization, we leverage a third-party IT service provider for management of our information systems needs. Our IT service provider works closely with executive management in the assessment, identification and management of cybersecurity threats. Cybersecurity threats are prevented and detected by multiple approaches, including perimeter defense, vulnerability management, intrusion testing, multifactor authentication and data protection. We have also implemented a formal cybersecurity awareness program that includes cybersecurity training for all employees and relevant contractors and is integrated with our overall risk management process. Material risks from cybersecurity threats, including those associated with the use of third-party service providers, are assessed during our annual review of our enterprise risks and related controls.

Our overall Board has oversight of all enterprise risks, including those arising from cybersecurity threats. The Board has not assigned that responsibility to any committee or subcommittee of the Board. Assessments of ongoing and emerging enterprise risks, including cybersecurity threats, if applicable, are an integral part of our regularly scheduled Board meetings.

We have an informal cyber incident response plan for mitigating and remediating cybersecurity threats and incidents. Any identified cybersecurity threats and incidents are promptly reported to executive management who, along with our IT professionals, will assess the severity of the event and formulate a response. Our determination of the severity of a cybersecurity incident would generally include an evaluation of the incident's effect on the Company, including (i) our business strategy, results of operations, or financial condition, (ii) the integrity, confidentiality, resiliency, and security of our networks and systems, and (iii) our operations. Based on the severity of the event, the Board will be notified and will provide strategic direction through the incident response and communication.

We rely on technology in all aspects of our business, including information systems of our third-party service providers. The information systems upon which we depend have been, and likely continue to be, subject to cybersecurity threats such as unauthorized access attempts, business email compromise, phishing, malware, ransomware, hacking and other cyberattacks attempting to disrupt operations. Our dependence on these information systems exposes us to cyberattacks, both directly and through cyberattacks impacting our service providers. A significant cybersecurity incident could result in service interruptions, security events, regulatory compliance failures, the inability to protect employee or corporate information or assets against unauthorized access or use, or other operational difficulties. As described above, we continuously monitor our cybersecurity threats, including risks associated with our use of service providers. We are not aware of any risks from cybersecurity threats, or previous cybersecurity incidents, that have materially affected or are reasonably likely to materially affect our business strategy, results of operations, or financial condition.

Item 2. Properties.

Since November 2020, we have operated in a fully remote worksite environment for all of our employees. We believe a remote work environment is currently suitable for the conduct of our business.

Item 3. Legal Proceedings.

We are a party to a number of patent enforcement actions initiated by us against others for the infringement of our technologies, as well as proceedings brought by others against us in an attempt to invalidate certain of our patent claims. In addition, we are currently in arbitration proceedings with a former litigation firm for disputed amounts due upon termination of the firm's engagement. These patent-related and other proceedings are more fully described in Note 12 to our consolidated financial statements included in Item 8.

Item 4. Mine Safety Disclosures.

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations.

Executive Overview

We are in the business of innovating and licensing our fundamental wireless technologies. We have designed and developed proprietary 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 U.S. and certain foreign jurisdictions. We believe certain patents protecting our proprietary technologies have been broadly infringed by others and therefore our business plan primarily consists of enforcement of our intellectual property rights through patent licensing efforts and infringement litigation. We currently have patent enforcement actions ongoing in various U.S. district courts against mobile handset, smart television and other WiFi product providers, as well as semiconductor suppliers, for the infringement of a number 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.

Table of Contents

We continue to aggressively pursue licensing opportunities with wireless communications companies that make, use or sell semiconductors and/or products that incorporate RF technologies. We believe there are a number of wireless communications companies that can benefit from the use of the RF technologies we have developed, whether through a license or, in certain cases, a joint product venture that may include licensing rights. Our licensing efforts to date have required litigation in order to enforce and/or defend our intellectual property rights. Since 2011, we have been involved in patent infringement litigation against Qualcomm and subsequently others for the unauthorized use of our technology. Refer to Note 12 to our consolidated financial statements included in Item 8 for a complete discussion of our legal proceedings. We have expended significant resources since 2011 and incurred significant debt for the enforcement and defense of our intellectual property rights. As of December 31, 2025, we had five licensees for our technologies.

Recent Developments

Legal Proceedings

In March 2026, our patent enforcement trial against MediaTek, scheduled to commence in the Western District of Texas, was postponed by the court pending updates to expert reports and related briefings by the parties. The court will issue a revised pretrial and trial schedule following its receipt of these submissions.

In January 2026, the CAFC granted our motion for an expected appeal of district court decisions in our patent infringement action against Qualcomm in the Middle District of Florida (Orlando division). Briefings by both parties are expected to be completed by March 2026 with oral arguments scheduled by the CAFC for the next available session after completion of briefing.

Refer to Note 12 to our consolidated financial statements included in Item 8 for a complete discussion of our patent enforcement proceedings.

Financing

In March 2026, we issued 3.3 million shares of our common stock in satisfaction of approximately $0.7 million in convertible debt and related accrued interest that was scheduled to mature in March 2026.

In November 2025, we completed two registered direct offerings with accredited investors under a shelf registration statement ("Shelf") for net proceeds of approximately $4.4 million. These proceeds are being used to fund our ongoing operations.

Liquidity and Capital Resources

With the exception of the year ended December 31, 2023, we have incurred significant losses from operations and negative cash flows in every year since inception, largely as a result of our significant investments in developing advanced technologies and protecting our intellectual property. We have utilized the proceeds from sales of debt and equity securities and contingent funding arrangements with third parties to fund our operations, including the cost of litigation to enforce our intellectual property rights. At December 31, 2025, we had cash and cash equivalents of approximately $4.4 million, working capital of $2.3 million, and an accumulated deficit of approximately $455.6 million.

For the year ended December 31, 2025, we incurred a net loss of approximately $7.4 million and used cash for operations of approximately $5.1 million. A significant amount of future proceeds that we may receive from our patent enforcement and licensing programs will be utilized to repay borrowings, legal fees, and litigation expenses under our contingent funding arrangements. We have $0.9 million in convertible debt, at conversion prices ranging from $0.08 to $0.13 per share, with maturity dates between July 2026 and January 2027 that we anticipate will be converted or extended in accordance with the current terms of the notes. Additionally, we issued 3.3 million shares of our common stock in March 2026 in satisfaction of $0.7 million in convertible debt and related accrued interest that matured in March 2026. Although all of our remaining convertible notes have conversion prices that are below the market price of our common stock, conversion is at the option of the holder and there can be no assurance that the holders will exercise their conversion option prior to maturity. Our independent registered public accounting firm has included in their audit report an explanatory paragraph expressing substantial doubt about our ability to continue as a going concern. See Note 2 to our consolidated financial statements included in Item 8 for a discussion of our liquidity and our ability to continue as a going concern.

Table of Contents

We used cash for operations of approximately $5.1 million and $3.2 million for the years ended December 31, 2025 and 2024, respectively. The increase in cash used for operations from 2024 to 2025 is primarily due to reductions in wages payable and other accrued liabilities from 2024 to 2025, along with an increase in prepaid insurance and prepaid services in 2025.

We paid approximately $0.1 million and $0.2 million in debt obligations during the years ended December 31, 2025 and 2024, respectively. During the years ended December 31, 2025 and 2024, we received aggregate net proceeds from equity-based financings and option and warrant exercises of approximately $4.8 million and $5.8, respectively.

Significant portions of our litigation costs to date have been funded by contingent payment arrangements with legal counsel. Fee discounts offered by legal counsel in exchange for contingent payments upon successful outcome in our litigation are not recognized in expense until such time that the related proceeds on which the contingent fees are payable are considered probable. Contingent fees vary based on each firm’s specific fee agreement. We currently have contingent fee arrangements in place for all of our active cases. In addition to our contingent fee agreements with legal counsel, we have secured and unsecured contingent payment obligations to third parties that have priority payments due from patent-related proceeds as discussed more fully under “Financial Condition - Contingent Payment Obligations” below.

Based on our current outstanding legal proceedings, funding arrangements and contingent payment arrangements, we estimate that up to 100% of our initial future proceeds will be used to repay contingent payment arrangements at least until the first $5.8 million of outstanding principal under our secured contingent payment obligation has been repaid. After repayment of $5.8 million in principal, we estimate that at least 75% of future proceeds could be payable to others until such time that certain minimum repayments have been achieved or our non recourse note matures in August 2028. The amount of proceeds payable to others depends on the proceeding and the nature, amount and timing of proceeds, among other factors.

Patent enforcement litigation is costly and time-consuming, and the outcome is difficult to predict. We expect to continue to invest in the support of our patent enforcement and licensing programs. We expect that cash flows generated from proceeds received from patent enforcement actions and/or technology licenses in 2026, after deduction of contingent payment obligations, may not be sufficient to cover our operating expenses and debt repayment obligations. In the event we do not generate revenues, or other patent-related proceeds, sufficient to cover our operational costs and contingent repayment obligations, we will be required to raise additional working capital through the sale of debt or equity securities or other financing arrangements.

The long-term continuation of our business plan is dependent upon our ability to secure sufficient financing to support our business, and our ability to generate revenues and/or patent-related proceeds sufficient to offset expenses and meet our contingent payment obligations and other long-term debt repayment obligations. Failure to generate sufficient revenues, raise additional capital through debt or equity financings, and/or reduce operating costs could have a material adverse effect on our ability to meet our short and long-term liquidity needs and achieve our intended long-term business objectives.

Financial Condition

Intangible Assets

We consider our intellectual property, including patents, patent applications, trademarks, copyrights, and trade secrets to be significant to our business. Our intangible assets are pledged as security for our secured contingent payment obligation with Brickell. The net book value of our intangible assets was approximately $0.7 million and $0.8 million as of December 31, 2025 and 2024, respectively. The cost basis for our intangible assets represents capitalized legal costs and agency filing fees for securing intellectual property protection and does not include the costs expended in developing the underlying intellectual property. The cost of our intangible assets is amortized using the straight-line method over their estimated period of benefit, generally fifteen to twenty years. The decrease in the carrying value of our intangible assets is primarily the result of $0.2 million in patent amortization expense recognized in 2025 as our portfolio matures. Management evaluates the recoverability of intangible assets periodically and considers events or circumstances that may warrant revised estimates of useful lives or that may indicate impairment exists. As part of our ongoing patent maintenance program, we may, from time to time, abandon a particular patent if we determine fees to maintain the patent exceed its expected recoverability.

Table of Contents

Contingent Payment Obligations

We have secured and unsecured contingent payment obligations recorded at an aggregate estimated fair value of $46.1 million and $46.7 million as of December 31, 2025 and 2024, respectively. These repayment obligations are contingent upon receipt of proceeds from patent enforcement and other patent monetization actions. We have elected to account for these contingent payment obligations at their estimated fair values which are subject to significant estimates and assumptions as discussed in “Critical Accounting Policies” below. Refer to Note 10 to our consolidated financial statements included in Item 8 for a discussion of the fair value measurement of our contingent payment obligations. The fair value of our contingent payment obligations may fluctuate significantly from period to period based on unpredictable changes in the status of our various patent litigation actions.

Our secured contingent payment obligation is payable to Brickell as a result of $23 million in aggregate borrowings under litigation funding arrangements initiated in 2016. As of December 31, 2025, we have repaid Brickell an aggregate of $17.3 million to date under these agreements. The contingent payment obligation to Brickell is recorded at its estimated fair market value of $39.7 million at December 31, 2025, a decrease of $1.1 million or 3% from the estimated fair market value at December 31, 2024. This decrease in fair value is primarily the result of changes in the estimated amounts and timing of projected future cash flows due to changes in probabilities and time frames based on the status of various patent infringement actions.

Brickell is entitled to the first $5.8 million in proceeds received by us, net of contingent legal fees, from any patent-related actions. Thereafter, Brickell is entitled to a prorated percentage of net proceeds. The underlying carrying value of the contingent payment obligation is represented by a non recourse note with a face value of $45.5 million, plus accrued interest of approximately $21.9 million as of December 31, 2025. The note matures on August 14, 2028. If our repayments to Brickell are insufficient to repay the face value of the note plus accrued interest by the maturity date, our remaining repayment obligations under the note will be reduced to zero with future payment obligations, if any, being determined under a separate prepaid forward purchase agreement that entitles Brickell to a specified percentage of monetary recoveries resulting from patent-related actions to the extent not already paid to Brickell under the note or previous litigation funding agreements.

In addition, we have incurred unsecured contingent payment obligations in connection with various funding arrangements. These contingent payment obligations are payable from our share of patent-related proceeds after satisfaction of our priority obligation to Brickell and payment of contingent fees to legal counsel. These unsecured contingent payment obligations are recorded at an aggregate estimated fair value of $6.4 million at December 31, 2025, representing an increase of $0.5 million, or 8.5% from the estimated fair market value at December 31, 2024. This increase is primarily the result of changes in the estimated amounts and timing of projected future cash flows due to changes in probabilities and time frames based on the status of various patent infringement actions. The maximum payment obligation for our unsecured contingent payment obligations is $10.8 million at December 31, 2025.

See “Change in Fair Value of Contingent Obligations” included in “Results of Operations” below for a discussion of the changes in the estimated fair values of our secured and unsecured contingent payment obligations.

Note Payable

As of December 31, 2025, we have a $0.2 million unsecured note payable to Sterne, Kessler, Goldstein, & Fox, PLLC (“SKGF”), a related party. The note calls for monthly payments of $12,500 through March 2027 with a final payment of approximately $0.02 million in April 2027. Failure to comply with the payment terms of this note constitutes an event of default which, if uncured, will result in the entire unpaid principal balance of the note and any unpaid, accrued interest to become immediately due and payable. In addition, an event of default results in an increase in the interest rate under the notes to a default rate of 12% per annum. Notes payable are discussed more fully in Note 7 to our consolidated financial statements included in Item 8.

Table of Contents

Convertible Notes

As of December 31, 2025 and 2024, we had $3.1 million and $3.5 million, respectively in notes, convertible at the holders’ option, into shares of our common stock at fixed conversion prices ranging from $0.08 to $0.25 per share. The decrease in the carrying value of our convertible notes is the result of approximately $0.4 million in notes that were converted into approximately 3.0 million shares of our common stock during 2025. The outstanding convertible notes as of December 31, 2025 mature at varying dates from January 2026 to January 2028. Notes representing approximately 45% of the outstanding principal balance are held by a single party and contain provisions for automatic extension of the maturity dates of the notes by up to ten one-year periods, if not revoked at the option of the holder.

The notes bear interest at stated rates ranging from 7.5% to 9% per annum and interest is generally payable quarterly. We have the option, subject to certain conditions, to pay the quarterly interest in-kind with shares of our common stock based on the market price of our common stock at the interest payment date. To date, nearly all of the interest payments under these convertible notes have been paid in-kind, and we anticipate that future payments of interest will also be paid in-kind to the extent allowable. The notes provide for events of default that include failure to pay principal or interest when due, breach of any of the representations made by us, events of liquidation or bankruptcy, and a change in control. In the event of default, the interest rate increases to 12% per annum and the outstanding principal balance of the notes plus all accrued interest due may be declared immediately payable by the holders of a majority of the then-outstanding notes. Our convertible notes payable are more fully discussed in Note 8 to our consolidated financial statements included in Item 8.

Deferred Tax Assets and Related Valuation Allowance

Deferred tax assets and liabilities are recognized for the expected future tax consequences of events that have been included in the financial statements or tax returns. Deferred tax assets and liabilities are determined based on differences between the financial statement carrying amounts and the tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. Valuation allowances are established to reduce deferred tax assets when, based on available objective evidence, it is more likely than not that the benefit of such assets will not be realized. As of December 31, 2025, we had net deferred tax assets of approximately $79.9 million, primarily related to our NOL carryforwards, which were fully offset by a valuation allowance due to the uncertainty related to realization of these assets through future taxable income. In addition, our ability to benefit from our NOL and other tax credit carryforwards could be limited under Section 382 as more fully discussed in “Risk Factors” and in Note 11 to our consolidated financial statements included in Item 8.

Results of Operations for Each of the Years Ended December 31, 2025 and 2024

Revenues and Gross Margins

We reported no licensing revenue for the years ended December 31, 2025 and 2024. Our licensing revenue is from patent licensing and settlement agreements resulting from patent enforcement actions filed by us. To date, all of our license and settlement agreements have consisted of a one-time, lump sum payment with no recurring future revenue. We recognized revenue from each contract when the parties’ performance obligations were met. Cost of sales related to the licensing revenue consists of amortization expense for the patents covered under the license agreements. Our licensing revenue is expected to vary based on the market size of the licensee and the specific terms of the license and settlement agreement.

Although we anticipate additional revenue to result from our licensing and patent enforcement actions, the amount and timing is highly unpredictable and there can be no assurance that we will achieve our anticipated results.

Table of Contents

Selling, General, and Administrative Expenses

Selling, general and administrative expenses consist primarily of executive, director, technical support, and finance and administrative personnel and third-party consulting costs, including share-based compensation, costs incurred for insurance, shareholder relations and outside legal and professional services, including litigation expenses, and maintenance expenses related to our patent assets.

Our selling, general and administrative expenses were approximately $7.6 million for the year ended December 31, 2025, as compared to approximately $4.3 million for the year ended December 31, 2024, representing an increase of approximately $3.3 million or 78%. This increase results primarily from a $2.9 million increase in total share-based compensation and a $0.8 million increase in third-party consulting and lobbying fees, partially offset by a $0.4 million decrease in personnel related expenses.

The increase in share-based compensation is the result of new share-based compensation awards to non-employee directors and third-party consultants, as well as a one-time, noncash charge of $2.5 million which reflects the compensation cost recognized upon the modification of awards for executives and key employees during the second quarter of 2025 to extend the maturity date of those awards by five years. The increases in third-party consulting and lobbying fees is a result of increased expenditures related to our social media and public awareness campaigns and business and financial advisory services incurred in 2025. The decrease in personnel related expenses is due to 2024 bonuses to executives and other key employees, partially offset by increased base salaries for executives and key employees in 2025.

Change in Fair Value of Contingent Payment Obligations

We have elected to measure our secured and unsecured contingent payment obligations at fair value which is based on significant unobservable inputs. We estimated the fair value of our secured contingent payment obligations using a probability-weighted income approach based on the estimated present value of projected future cash outflows using a risk-adjusted discount rate. Increases or decreases in the significant unobservable inputs could result in material increases or decreases in fair value. Generally, changes in fair value are a result of changes in estimated amounts and timing of projected future cash flows resulting from increases in funded amounts, changes in estimated potential proceeds, the passage of time, and changes in the probabilities based on the litigation status of the funded actions.

For the year ended December 31, 2025, we recorded a net decrease in the aggregate fair value of our secured and unsecured contingent payment obligations of approximately $0.6 million, compared to an increase in the aggregate fair value of approximately $9.6 million for the year ended December 31, 2024. The majority of the change in fair value is attributable to changes in the estimated amounts and timing of projected future cash flows due to changes in the litigation status of various patent infringement actions. The significant increase in fair value in 2024 was, in part, the result of a September 2024 favorable CAFC decision that remanded our infringement action against Qualcomm to the district court.

Critical Accounting Policies

We believe that the following are critical accounting policies and estimates that significantly impact the preparation of our consolidated financial statements:

Contingent Payment Obligations

We have accounted for our secured and unsecured contingent payment obligations as long-term debt. Our repayment obligations are contingent upon the receipt of proceeds from patent enforcement or other patent monetization actions. We have elected to measure our contingent payment obligations at their estimated fair values based on the variable and contingent nature of the repayment provisions. We have determined that the fair value of our secured and unsecured contingent payment obligations falls within Level 3 in the fair value hierarchy, which involves significant estimates and assumptions including projected future patent-related proceeds and the risk-adjusted rate for discounting future cash flows. Actual results could differ materially from the estimates made. Changes in fair value, including the component related to imputed interest, are included in the consolidated statements of comprehensive loss under the heading “Change in fair value of contingent payment obligations.” Refer to Note 10 to our consolidated financial statements included in Item 8 for a discussion of the significant estimates and assumptions used in estimating the fair value of our contingent payment obligations.

New Accounting Pronouncements

In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40) - Disaggregation of Income Statement Expenses. This update requires disclosure of the amounts of purchases of inventory, employee compensation, depreciation, and intangible asset amortization included in each relevant expense line item on the income statement. The standard also requires a qualitative description of other amounts included in each relevant expense line item on the income statement that are not separately disclosed. In addition, entities are required to disclose the nature and amount of selling expenses. The amendments in ASU 2024-03 are effective for annual periods beginning after December 15, 2026, which for the Company would be applicable to fiscal year 2027, and for subsequent interim periods. Early adoption is permitted and the amendments should be applied on a prospective basis. Retrospective application is permitted. Adoption of this guidance will result in additional disclosures, but we do not expect the adoption of ASU 2024-03 to materially impact our consolidated financial statements.

In November 2024, the FASB issued ASU 2024-04, Debt - Debt with Conversion and Other Options (Subtopic 470-20) - Induced Conversions of Convertible Debt Instruments. This update clarifies the assessment of whether a transaction should be accounted for as an induced conversion or extinguishment of convertible debt when changes are made to conversion features as part of an offer to settle the instrument. ASU 2024-04 is effective for reporting periods beginning after December 15, 2025, and interim periods within those annual reporting periods. Early adoption is permitted for entities that have adopted ASU 2020-06, Accounting for Convertible Instruments and Contracts in an Entity's Own Equity (Subtopics 470-20 and 815-40). We are currently evaluating the impact of this new accounting guidance.

Off-Balance Sheet Transactions

As of December 31, 2025, we had outstanding warrants to purchase 4.3 million shares of our common stock. The estimated grant date fair value of these warrants of approximately $3.0 million is included in shareholders’ deficit in our consolidated balance sheet for the year ended December 31, 2025. The outstanding warrants have an average exercise price of $1.05 per share and a weighted average remaining life of approximately 2.1 years.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and Board of Directors of ParkerVision, Inc.

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of ParkerVision, Inc. (the “Company”) as of December 31, 2025 and 2024, and the related consolidated statements of comprehensive loss, changes in shareholders’ deficit, and cash flows for the years then ended, and the related notes (collectively referred to as the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2025 and 2024, and the results of its operations and cash flows for the years then ended, in conformity with accounting principles generally accepted in the United States of America.

Substantial Doubt About the Company's Ability to Continue as a Going Concern

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 2 to the consolidated financial statements, the Company has losses from operations, negative operating cash flows and an accumulated deficit. These factors raise substantial doubt about the Company's ability to continue as a going concern. Management’s plans in regard to these matters are also described in Note 2. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s consolidated financial statements based on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) ("PCAOB") and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As a part of our audit, we are required to obtain an understanding of internal control over financial reporting, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audit included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audit provides a reasonable basis for our opinion.

Table of Contents

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing separate opinions on the critical audit matter or on the accounts or disclosures to which they relate.

Fair Value of Contingent Payment Obligations

As described in Notes 1, 9 and 10 to the consolidated financial statements, the Company has recorded the contingent payment obligations at fair value as of December 31, 2025. To determine the fair value of contingent payment obligations, the Company uses a present value technique based on discounted cash flows to estimate the fair value.

We determined the fair value of contingent payment obligations listed above was a critical audit matter because the fair value estimates require significant estimates and assumptions by management, including those relating to future patent-related cash proceeds and discount rates. Testing these estimates and obtaining sufficient audit evidence involved increased auditor judgment and effort.

Our audit procedures related to the valuation of the contingent payment obligations included the following, among others:

	●	We obtained an understanding and evaluated the appropriateness of management's valuation methodology, including testing the mathematical accuracy of the calculation.

	●	We engaged an external patent litigation specialist to assist with discussions with the Company's patent litigation attorneys in understanding and evaluating significant assumptions used in management's estimate of the fair value of the contingent payment obligations.

	●	We performed sensitivity analyses of the timing of future cash flows to evaluate changes in the fair value of the contingent payment obligations.

	●	We assessed the reasonableness of the discount rates utilized by management in estimating the fair value of the contingent payment obligations.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

December 31, 2025 and 2024

1. SIGNIFICANT ACCOUNTING POLICIES

ParkerVision, Inc. (collectively “ParkerVision”, “we” or the “Company”) is in the business of innovating and licensing fundamental wireless technologies. We have determined that our business currently operates under a single operating and reportable segment.

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 licensing and infringement litigation efforts. We currently have patent enforcement actions ongoing in various U.S. district courts against mobile handset, smart television and other WiFi product providers, as well as semiconductor suppliers, for the infringement of a number 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.

Basis of Presentation

Our consolidated financial statements are prepared in accordance with generally accepted accounting principles in the U.S. (“GAAP”). Certain reclassifications have been made to prior period amounts to conform to the current period presentation.

Use of Estimates in the Preparation of Financial Statements

The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. The more significant estimates made by us include projected future cash flows and risk-adjusted discount rates for estimating the fair value of our contingent payment obligations. Other estimates include the estimated lives of share-based awards used in the estimate of the fair market value of share-based compensation, the assessment of recoverability of long-lived assets, the amortization periods for intangible and long-lived assets, and the valuation allowance for deferred taxes. Actual results could differ from the estimates made. We periodically evaluate estimates used in the preparation of the financial statements for continued reasonableness. Appropriate adjustments, if any, to the estimates used are made prospectively based upon such periodic evaluation.

Cash and Cash Equivalents

We consider cash and cash equivalents to include cash on hand, interest-bearing deposits, overnight repurchase agreements and investments with original maturities of three months or less when purchased.

Intangible Assets

We capitalize outside legal costs and agency filing fees incurred in connection with securing the rights to our intellectual property. Patents, copyrights, and other intangible assets are amortized using the straight-line method over their estimated period of benefit. We estimate the economic lives of our patents and copyrights to be fifteen to twenty years. Management evaluates the recoverability of intangible assets periodically and considers events or circumstances that may warrant revised estimates of useful lives or that may indicate impairment exists. As part of our ongoing patent maintenance program, we will, from time to time, abandon a particular patent if we determine fees to maintain the patent exceed its expected recoverability. The cost and accumulated amortization of abandoned intangible assets are removed from their respective accounts, and any resulting net loss is recognized in selling, general and administrative expenses in the accompanying consolidated statements of comprehensive loss.

Table of Contents

Contingent Payment Obligations

We have accounted for our secured and unsecured contingent payment obligations as long-term debt in accordance with Accounting Standards Codification (“ASC”) 470-10-25, “Sales of Future Revenues or Various other Measures of Income.” Our payment obligations are contingent upon the receipt of proceeds from patent enforcement and/or patent monetization actions. We have elected to measure our contingent payment obligations at their estimated fair values in accordance with ASC 825, “Financial Instruments” based on the variable and contingent nature of the repayment provisions. We have determined that the fair value of our secured and unsecured contingent payment obligations falls within Level 3 in the fair value hierarchy, which involves significant estimates, and assumptions including projected future patent-related proceeds and the risk-adjusted rate for discounting future cash flows (see Note 10). Actual results could differ materially from the estimates made. Changes in fair value, including the component related to imputed interest, are included in the accompanying consolidated statements of comprehensive loss under the heading “Change in fair value of contingent payment obligations.”

Revenue Recognition

We account for revenue under ASC 606, “Revenue from Contracts with Customers” which implements a common revenue standard that clarifies the principles for recognizing revenue. This revenue recognition model provides a five-step analysis in determining when and how revenue is recognized. These steps include (1) identifying the contract with the customer, (2) identifying the performance obligations, (3) determining the transaction price, (4) allocating the transaction price to the performance obligations, and (5) recognizing revenue as the entity satisfies the performance obligation(s).

Our revenue is derived from patent licensing and settlement agreements. We have an active monitoring and enforcement program with respect to our intellectual property rights that includes seeking appropriate compensation from third parties that utilize or have utilized our intellectual property without a license. As a result, we may receive payments as part of a settlement or in the form of court-awarded damages for a patent infringement dispute. The timing and amount of revenue recognized from each licensee depend upon a variety of factors, including the specific terms of each agreement and the nature of the deliverables and obligations. Such agreements are often complex and may include multiple performance obligations. These agreements can include performance obligations related to the settlement of past patent infringement liabilities, royalties on future covered products sold by licensees, access to a portfolio of technology as it exists at a point in time, and/or promises to provide technology updates to the portfolio during the term of the license.

Refer to Note 3 for additional disclosures related to our revenue.

Cost of Sales

Cost of sales includes amortization of intangible assets directly linked with revenue generating licensing activities. Amortization expense for intangible assets that are not directly related to revenue generating licensing activities are included in selling, general, and administrative expenses in our consolidated statements of comprehensive loss. As a result of the confidential patent license and settlement agreement reached in February 2023, all of our patents are now directly linked with revenue generating licensing activities and, therefore, amortization expense for all intangible assets is now recorded to cost of sales.

Accounting for Share-Based Compensation

We have various share-based compensation programs which provide for equity awards including stock options, restricted stock units (“RSUs”) and restricted stock awards (“RSAs”). We calculate the fair value of share-based equity awards on the date of grant and recognize the calculated fair value as compensation expense over the requisite service periods of the related awards. We estimate the fair value of stock option awards using the Black-Scholes option valuation model. This valuation model requires the use of subjective assumptions and estimates including how long persons will retain their stock options before exercising them and the volatility of our common stock price over the expected life of the equity award. Such estimates, and the basis for our conclusions regarding such estimates, are outlined in detail in Note 14. Estimates of fair value are not intended to predict actual future events or the value ultimately realized by persons who receive equity awards. We account for forfeitures of share-based awards as they occur.

Table of Contents

Income Taxes

The provision for income taxes is based on loss before taxes as reported in the accompanying consolidated statements of comprehensive loss. Deferred tax assets and liabilities are recognized for the expected future tax consequences of events that have been included in the financial statements or tax returns. Deferred tax assets and liabilities are determined based on differences between the financial statement carrying amounts and the tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. Valuation allowances are established to reduce deferred tax assets when, based on available objective evidence, it is more likely than not that the benefit of such assets will not be realized. Our deferred tax assets exclude unrecognized tax benefits which do not meet a more-likely-than-not threshold for financial statement recognition for tax positions taken or expected to be taken in a tax return.

New Accounting Pronouncements

2. LIQUIDITY AND GOING CONCERN

The accompanying consolidated financial statements as of and for the year ended December 31, 2025 were prepared assuming we will continue as a going concern, which contemplates that we will continue in operation and will be able to realize our assets and settle our liabilities and commitments in the normal course of business for a period of at least one year from the issuance date of these consolidated financial statements. These consolidated financial statements do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classification of liabilities that could result should we be unable to continue as a going concern.

Table of Contents

For the year ended December 31, 2025, we incurred a net loss of approximately $7.4 million and used cash from operations of approximately $5.1 million. For the year ended December 31, 2025, we made aggregate payments of approximately $0.1 million on long-term debt. We received aggregate net proceeds in 2025 from equity-based financings of $4.4 million and proceeds from option and warrant exercises of approximately $0.4 million. These proceeds are being used to support our operations.

A significant amount of future proceeds that we may receive from our patent enforcement and licensing programs will be utilized to repay borrowings, legal fees, and litigation expenses under our contingent funding arrangements. We have $0.9 million in convertible debt, at conversion prices ranging from $0.08 to $0.13 per share, with maturity dates between July 2026 and January 2027 that we anticipate will be converted or extended in accordance with the current terms of the notes. Additionally, we issued 3.3 million shares of our common stock in March 2026 in satisfaction of $0.7 million in convertible debt and related accrued interest that matured in March 2026 (see Note 18). Although all of our remaining convertible notes have conversion prices that are below the market price of our common stock, conversion is at the option of the holder and there can be no assurance that the holders will exercise their conversion option prior to maturity. These circumstances indicate there is substantial doubt about our ability to continue to operate as a going concern for a period of one year following the issue date of these consolidated financial statements.

Our business plan is currently focused predominantly on our patent enforcement and technology licensing objectives. The timing and amount of proceeds from our patent enforcement actions are difficult to predict and there can be no assurance we will receive any proceeds from these enforcement actions. Refer to Note 12 for a complete discussion of our patent enforcement proceedings.

Significant portions of our litigation costs to date have been funded by contingent payment arrangements with legal counsel. Fee discounts offered by legal counsel in exchange for contingent payments upon successful outcome in our litigation are not recognized in expense until such time that the related proceeds on which the contingent fees are payable are considered probable. Contingent fees vary based on each firm’s specific fee agreement. We currently have contingent fee arrangements in place for all of our active cases. In addition to our contingent fee agreements with legal counsel, we have secured and unsecured contingent payment obligations that have contingent payments due from patent-related proceeds which are reflected in our consolidated financial statements at their current fair values. These fair value measures are subject to substantial increases or decreases depending upon actual outcomes from our enforcement actions.

Table of Contents

Our current capital resources may not be sufficient to meet our liquidity needs for the twelve months following the issuance of our financial statements, and we may be required to seek additional capital. Our ability to meet our future liquidity needs is dependent upon (i) our ability to successfully negotiate licensing agreements and/or settlements relating to the use of our technologies by others in excess of our contingent payment obligations, (ii) our ability to control operating costs, (iii) the exercise behavior of our convertible note holders, and/or (iv) our ability to obtain additional debt or equity financing. We expect that proceeds received by us from patent enforcement actions and technology licenses over the next twelve months may not alone be sufficient to cover our long-term working capital requirements.

We expect to continue to invest in the support of our patent licensing and enforcement program. The long-term continuation of our business plan is dependent upon the generation of sufficient cash flows from our technology licenses to offset expenses and debt obligations. In the event that we do not generate sufficient cash flows, we will be required to obtain additional funding through public or private debt or equity financing or contingent fee arrangements and/or reduce operating costs. Failure to generate sufficient cash flows, raise additional capital through debt or equity financings or contingent fee arrangements, and/or reduce operating costs could have a material adverse effect on our ability to meet our short and long-term liquidity needs and achieve our intended long-term business objectives.

3. REVENUE

We reported no licensing revenue for the years ended December 31, 2025 and 2024. Revenue resulting from our patent enforcement actions is highly unpredictable with respect to the amount and timing of receipt.

4. LOSS PER SHARE

Basic loss per common share is determined based on the weighted-average number of common shares outstanding during each period. Diluted loss per common share is the same as basic loss per common share as all common share equivalents are excluded from the calculation, as their effect is anti-dilutive.

The number of shares underlying outstanding options, warrants, unvested RSUs, and convertible notes at December 31, 2025 and 2024 were as follows (in thousands):

	2025		2024
Options outstanding	24,669		25,451
Warrants outstanding		4,346		9,746
Unvested RSUs		296		250
Shares underlying convertible notes		24,678		27,724
		53,989		63,171

These potential shares were excluded from the computation of diluted loss per share as their effect would have been anti-dilutive.

7. NOTES PAYABLE

Note Payable to a Related Party

We have an unsecured promissory note payable of $0.2 million to Sterne, Kessler, Goldstein, & Fox, PLLC (“SKGF”), a related party (see Note 15), for outstanding unpaid fees for legal services. The note, as amended, accrues interest at 4% per annum and provides for monthly payments of principal and interest of $12,500 with a final balloon payment of approximately $0.02 million due at the maturity date of April 30, 2027. We recognized interest expense of approximately $0.01 and $0.02 million related to this note during the years ended December 31, 2025 and 2024, respectively. Principal repayments of $0.14 million and $0.13 million for the years ended December 31, 2025 and 2024, respectively, are included under the caption "Principal payments on long-term debt" in our consolidated statements of cash flows. Failure to comply with the payment terms of this note constitutes an event of default which, if uncured, will result in the entire unpaid principal balance of the note and any unpaid, accrued interest to become immediately due and payable. In addition, an event of default results in an increase in the interest rate under the notes to a default rate of 12% per annum.

At December 31, 2025, the aggregate maturities of our notes payable are as follows (in thousands):

2026	$	144
2027		57
Total	$	201

8. CONVERTIBLE NOTES

Our convertible notes represent promissory notes that are convertible, at the holders’ option, into shares of our common stock at fixed conversion prices. Interest payments are generally made on a quarterly basis and are payable, at our option and subject to certain equity conditions, in either cash, shares of our common stock, or a combination thereof. The number of shares issued for interest is determined by dividing the interest payment amount by the closing price of our common stock on the trading day immediately prior to the scheduled interest payment date. Upon conversion by the holder, any accrued and unpaid interest, if not paid in cash, is converted into shares of common stock at the conversion price. To date, nearly all interest payments on the convertible notes have been made in shares of our common stock. We have recognized the convertible notes as debt in our consolidated financial statements.

We have the option to prepay approximately 55% of the face value of the notes any time following the one-year anniversary of the issuance of the notes, subject to a premium on the outstanding principal prepayment amount of 25% prior to the two-year anniversary of the note issuance date, 20% prior to the three-year anniversary of the note issuance date, 15% prior to the four-year anniversary of the note issuance date, or 10% thereafter. The notes provide for events of default that include failure to pay principal or interest when due, breach of any of the representations, warranties, covenants, or agreements made by us, events of liquidation or bankruptcy, and a change in control. In the event of default, the interest rates increase to 12% per annum and the outstanding principal balance of the notes plus all accrued interest due may be declared immediately payable by the holders of a majority of the then outstanding principal balance of the notes.

No convertible notes matured or were repaid during the year ended December 31, 2025. For the year ended December 31, 2024, we repaid an aggregate of $0.05 million upon the maturity of convertible notes. Repayments of our convertible notes upon maturity are included in the caption "Principal payments on long-term debt" in our consolidated statements of cash flows. For the years ended December 31, 2025 and 2024, convertible notes with a face value of $0.4 million and $1.4 million, respectively, were converted by the holders into 3.0 million and 9.6 million shares of our common stock, respectively. We recognized interest expense of approximately $0.3 million and $0.4 million during the years ended December 31, 2025 and 2024, respectively. We have elected to pay contractual interest in shares of our common stock. For the years ended December 31, 2025 and 2024, we issued approximately 0.8 million and 2.0 million shares of our common stock, respectively, as interest-in-kind payments on our convertible notes.

Table of Contents

No convertible notes were amended during the year ended December 31, 2025. For the year ended December 31, 2024, we amended convertible notes with an aggregate face value of $2.35 million with the primary purpose of extending the maturity date of the notes. Each of the amendments was considered to be a troubled debt restructuring in accordance with ASC 470-60, and accordingly, the changes were accounted for prospectively and no gain or loss was recognized as a result of the note modifications.

At the holders’ option, subject to ownership limitations, the convertible notes outstanding at December 31, 2025 could be converted into an aggregate of approximately 24.7 million shares of our common stock based on the fixed conversion prices. All of the shares underlying our convertible notes, including shares reserved for future in-kind interest payments on the notes, have been registered for resale.

Convertible notes payable to non-related parties at December 31, 2025 and 2024, consist of the following (in thousands):

	Fixed

Less current portion								1,225		500
							$	1,908	$	2,798

¹Unless otherwise revoked by the holder within ten days of the then-stated maturity date, the maturity date of the note will automatically extend by one year, for a maximum of ten years.

In March 2026, we issued approximately 3.3 million unregistered shares of our common stock in exchange for the satisfaction of approximately $0.7 million in principal and accrued interest on convertible notes with March 2026 maturity dates (see Note 18).

We have no convertible notes payable to related parties as of December 31, 2025. At December 31, 2024, we had convertible notes payable to related parties with a face value of $0.2 million. These notes, which were converted in 2025, were issued in May 2022, had a fixed conversion price of $0.13, accrued interest at 8.0% per annum, and matured between May 10, 2027 and August 3, 2027.

9. CONTINGENT PAYMENT OBLIGATIONS

Secured Contingent Payment Obligation

The following table provides a reconciliation of our secured contingent payment obligation measured at estimated fair market value for the years ended December 31, 2025 and 2024, respectively (in thousands):

	2025			2024
Secured contingent payment obligation, beginning of year	$	40,724		$	29,402
Change in fair value		(1,074	)		11,322
Secured contingent payment obligation, end of year	$	39,650		$	40,724

Our secured contingent payment obligation represents the estimated fair value of our repayment obligation to Brickell Key Investments, LP (“Brickell”) under a February 2016 funding agreement, as amended from time to time. On August 14, 2023, the contingent funding agreement with Brickell was replaced with a secured, non-recourse note (the "Note") and a prepaid forward purchase agreement (the "PPFPA"). The Note has a face value of $45.5 million ("Face Value"), accrues simple interest at a fixed rate, and matures on August 14, 2028. Payments under the Note will be made solely from proceeds from our patent assets, net of contingent fees payable to attorneys ("Distributions"). We are obligated to pay one hundred percent (100%) of the first $5.8 million in Distributions to Brickell, and thereafter will pay a percentage of Distributions, which varies depending upon the origin of the Distributions, until the Face Value of the Note, and accrued interest thereon, has been repaid in full. If the amounts payable to Brickell from Distributions are insufficient to repay the face value and interest accrued on the Note by the maturity date, our remaining repayment obligations under the Note will be reduced to zero with future payment obligations, if any, being determined under the PPFPA. The Note is secured by our patent assets and related proceeds and contains standard and customary representations, warranties and covenants. The Note contains events of default including, but not limited to, (a) failure to pay principal or interest on the Note when due; (b) breach of representations or covenants, (c) impairment in the perfection or priority of Brickell's security interests in the collateral, and (d) bankruptcy or dissolution of the Company. In the event of a default, the outstanding principal and accrued interest on the Note will become immediately due and payable. The PPFPA extends beyond the maturity date of the Note and provides that Brickell is entitled to a specified percentage of monetary recoveries resulting from our patent-related actions to the extent not already paid to Brickell under the Note, or otherwise prior to the inception of the Note. The PPFPA also contains standard and customary representations, warranties and covenants. The Note and PPFPA are collectively referred to as our secured contingent payment obligation.

Since 2016, we have received aggregate proceeds of $23 million in exchange for Brickell’s right to reimbursement and compensation from gross proceeds resulting from patent enforcement and other patent monetization actions and have repaid an aggregate of $17.3 million from patent license and settlement proceeds. The underlying carrying value of the Note, which includes the Face Value plus accrued interest, was approximately $67.4 million and $59.2 million as of December 31, 2025 and 2024, respectively. The range of potential proceeds payable to Brickell is discussed more fully in Note 10.

Brickell holds a senior security interest in the majority of our assets until such time as the Note, including accrued interest thereon, is paid in full. The security interest is enforceable by Brickell in the event that we are in default under the agreement which would occur if (i) we fail, after notice, to pay proceeds to Brickell, (ii) we become insolvent or insolvency proceedings are commenced (and not subsequently discharged) with respect to us, (iii) our creditors commence actions against us (which are not subsequently discharged) that affect our material assets, (iv) we, without Brickell’s consent, incur indebtedness other than immaterial ordinary course indebtedness, or (v) there is an uncured non-compliance of our obligations or misrepresentations under the agreement.

Table of Contents

We have elected to measure our secured contingent payment obligation at its estimated fair value based on probability-weighted estimated cash outflows, discounted back to present value using a discount rate determined in accordance with accepted valuation methods (see Note 10). The secured contingent payment obligation is remeasured to fair value at each reporting period with changes recorded in the consolidated statements of comprehensive loss until the contingency is resolved.

Unsecured Contingent Payment Obligations

The following table provides a reconciliation of our unsecured contingent payment obligations, measured at estimated fair market value, for the years ended December 31, 2025 and 2024, respectively (in thousands):

	2025		2024
Unsecured contingent payment obligations, beginning of year	$	5,935	$	7,618
Change in fair value		504		(1,683	)
Unsecured contingent payment obligations, end of year	$	6,439	$	5,935

Our unsecured contingent payment obligations represent amounts payable to others from future patent-related proceeds including (i) a termination fee due to a litigation funder (“Termination Fee”) and (ii) contingent payment rights (“CPRs”) issued to accredited investors primarily in connection with equity financings. We have elected to measure these unsecured contingent payment obligations at their estimated fair value based on probability-weighted estimated cash outflows, discounted back to present value using a discount rate determined in accordance with accepted valuation methods. The unsecured contingent payment obligations will be remeasured to fair value at each reporting period with changes recorded in the consolidated statements of comprehensive loss until the contingency is resolved (see Note 10).

The Termination Fee is a result of $1.0 million in advances received under a letter agreement with a third-party funder. Based on the terms of the letter agreement, if a final funding arrangement was not executed by March 31, 2020, we would be obligated to pay, from future patent-related proceeds, an aggregate termination payment equal to five times the advances received, or approximately $5.0 million. We did not consummate a funding agreement and accordingly the advances were recorded as an unsecured contingent payment obligation at March 31, 2020, when the Termination Fee obligation was incurred. As of December 31, 2025, the estimated fair value of unsecured contingent payment obligations related to the Termination Fee is $3.0 million.

The CPRs represent the estimated fair value of rights provided to accredited investors who purchased shares of our common stock in 2020 and 2021 and the fair value of a right issued to a third-party in connection with a service agreement during the year ended December 31, 2020. The terms of the CPRs provide that we will pay each investor an allocated portion of our net proceeds from patent-related actions, after taking into account fees and expenses payable to law firms representing us and amounts payable to Brickell. The investors’ allocated portion of net proceeds will be determined by multiplying the net proceeds recovered by us (up to $10 million) by the quotient of such investors’ subscription amount divided by $10 million, up to an amount equal to each investor’s subscription amount, or an aggregate of $5.8 million. As of December 31, 2025, the estimated fair value of our unsecured contingent payment obligations related to the CPRs is $3.4 million.

10. FAIR VALUE MEASUREMENTS

ASC 820, “Fair Value Measurements” establishes a fair value hierarchy that prioritizes the inputs to valuation methods used to measure fair value. The three levels of the fair value hierarchy are as follows:

●

Level 1: Quoted prices for identical assets or liabilities in active markets which we can access

●

Level 2: Observable inputs other than those described in Level 1

●

Level 3: Unobservable inputs

The fair values of cash and cash equivalents, prepaid and other current assets, accounts payable, accrued expenses and other current liabilities approximate their carrying values because of the short-term nature of these instruments.

Our convertible notes, which are recorded at face value in the consolidated balance sheets as of December 31, 2025 and 2024 have an estimated fair value of approximately $2.8 million.

The following table summarizes financial assets and financial liabilities carried at fair value and measured on a recurring basis as of December 31, 2025 and 2024, segregated by classification within the fair value hierarchy (in thousands):

			Fair Value Measurements
	Total		Quoted Prices in Active Markets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)
December 31, 2025:
Liabilities:
Secured contingent payment obligation	$	39,650	$	-	$	-	$	39,650
Unsecured contingent payment obligations		6,439		-		-		6,439


December 31, 2024:
Liabilities:
Secured contingent payment obligation		40,724		-		-		40,724
Unsecured contingent payment obligations		5,935		-		-		5,935

For the years ended December 31, 2025 and 2024, respectively, we had no transfers of assets or liabilities between the levels of the hierarchy.

The fair values of our secured and unsecured contingent payment obligations were estimated using a probability-weighted income approach based on various cash flow scenarios as to the outcome of patent-related actions both in terms of timing and amount, discounted to present value using a risk-adjusted rate. We used a risk-adjusted discount rate for the secured and unsecured contingent payment obligations of 17.55% and 17.47%, respectively, at December 31, 2025, based on a risk-free rate of 3.55% and 3.47%, respectively, as adjusted by 8% for credit risk and 6% for litigation inherent risk. We used a risk-adjusted discount rate for the secured and unsecured contingent payment obligations of 18.27% and 18.21%, respectively, at December 31, 2024, based on a risk-free rate of 4.27% and 4.21%, respectively, as adjusted by 8% for credit risk and 6% for litigation inherent risk.

Table of Contents

The following tables provide quantitative information about the significant unobservable inputs used in the measurement of fair value for both the secured and unsecured contingent payment obligations at December 31, 2025 and 2024, respectively, including the lowest and highest undiscounted payout scenarios as well as a weighted average payout scenario based on relative undiscounted fair value of each cash flow scenario.

December 31, 2025
	Secured Contingent Payment Obligation									Unsecured Contingent Payment Obligations
Unobservable Inputs	Low			Weighted Average			High			Low			Weighted Average			High

Estimated probabilities		15	%		19	%		25	%		15	%		21	%		25	%

We evaluate the estimates and assumptions used in determining the fair value of our contingent payment obligations each reporting period and make any adjustments prospectively based on those evaluations. Changes in any of these Level 3 inputs could result in a significantly higher or lower fair value measurement.

11. INCOME TAXES AND TAX STATUS

Our net losses before income tax for the years ended December 31, 2025 and 2024 are from domestic operations.

No current or deferred tax benefits were recorded in either 2025 or 2024 as a result of current losses and full deferred tax valuation allowances. We have recorded a valuation allowance to state our remaining deferred tax assets at their estimated net realizable value due to the uncertainty related to realization of these assets through future taxable income.

Table of Contents

We adopted the guidance in ASU 2023-09, "Income Taxes - Improvements to Income Tax Disclosures", during the year ended December 31, 2025, which requires enhanced disclosures on income taxes paid and defines specific categories for the reconciliation of jurisdictional tax rate to effective tax rate. A reconciliation between the provision for income taxes and the expected tax benefit using the federal statutory rate of 21% for each of the years ended December 31, 2025 and 2024, respectively, are as follows (in thousands):

	2025				2024
	Amount			Percent of Net loss before income tax	Amount			Percent of Net loss before income tax
Tax benefit at statutory rate	$	(1,559	)	(21.0%)	$	(3,039	)	(21.0%)

Our deferred tax assets and liabilities relate to the following sources and differences between financial accounting and the tax bases of our assets and liabilities at December 31, 2025 and 2024 (in thousands):

	2025			2024
Gross deferred tax assets:
Net operating loss carry-forward	$	63,807		$	67,899

Net deferred tax asset	$	-		$	-

At December 31, 2025, we had cumulative NOL carry-forwards for income tax purposes of $254.7 million, of which $203.9 million is subject to expiration in varying amounts from 2026 to 2037. At December 31, 2025, we also had research and development tax credit carryforwards of $3.5 million, which expire in varying amounts from 2026 through 2037.

Our ability to benefit from the NOL and tax credit carry-forwards could be limited under certain provisions of the Internal Revenue Code if there are ownership changes of more than 50%, as defined by Section 382 of the Internal Revenue Code of 1986 (“Section 382”). Under Section 382, an ownership change may limit the amount of NOL, capital loss and R&D credit carry-forwards that can be used annually to offset future taxable income and tax, respectively. In general, an ownership change, as defined by Section 382, results from transactions increasing the ownership of certain shareholders or public groups in the stock of a corporation by more than 50 percentage points over a three-year period. We conduct a study annually of our ownership changes. Based on the results of our studies, we have determined that we do not have any ownership changes on or prior to December 31, 2025 which would result in limitations of our NOL, capital loss or R&D credit carry-forwards under Section 382.

Uncertain Tax Positions

We file income tax returns in the U.S. federal jurisdiction and various state jurisdictions. We have identified our Federal and Florida tax returns as our only major jurisdictions, as defined. The periods subject to examination for those returns are the 2004 through 2025 tax years. Unrecognized tax benefits due to uncertain tax positions were $0.64 million for each of the years ended December 31, 2025 and 2024.

Future changes in the unrecognized tax benefit will have no impact on the effective tax rate so long as we maintain a full valuation allowance.

Our policy is that we recognize interest and penalties accrued on any unrecognized tax benefits as a component of our income tax expense. We do not have any accrued interest or penalties associated with any unrecognized tax benefits. For the years ended December 31, 2025 and 2024, we did not incur any income tax-related interest income, expense or penalties.

12. COMMITMENTS AND CONTINGENCIES

Legal Proceedings

From time to time, we are subject to legal proceedings and claims which arise in the ordinary course of our business. These proceedings include patent enforcement actions initiated by us against others for the infringement of our technologies, as well as proceedings brought by others against us at the Patent Trial and Appeal Board of the U.S. Patent and Trademark Office (“PTAB”) in an attempt to invalidate certain of our patent claims. The majority of our litigation, including our PTAB proceedings, is being paid for through contingency fee arrangements with our litigation counsel as well as third-party litigation financing. In general, litigation counsel is entitled to recoup on a priority basis, from litigation proceeds, any out-of-pocket expenses incurred. Following reimbursement of out-of-pocket expenses, litigation counsel is generally entitled to a percentage of remaining proceeds based on the terms of the specific arrangement between us, counsel and our third-party litigation funder. In addition, we are currently in arbitration proceedings with a former litigation firm for disputed amounts due upon termination of that firm's engagement. We have been indemnified by our subsequent litigation firm for the costs of these proceedings.

ParkerVision v. Qualcomm (Middle District of Florida-Orlando Division) - Appealed to U.S. Court of Appeals for the Federal Circuit

ParkerVision v. Qualcomm currently has a second appeal underway at the United States Court of Appeals for the Federal Circuit ("CAFC") with respect to this case.

This patent infringement case was originally filed in the Middle District of Florida in May 2014. The case was stayed in 2016 pending decisions in other cases, including the appeal of a PTAB proceeding with regard to U.S. patent 6,091,940 (“the ‘940 Patent”) asserted in this case. In 2017, the PTAB ruled in our favor on three of the six petitions (the method claims), ruled in Qualcomm’s favor on two of the six petitions (the apparatus claims) and issued a split decision on the claims covered in the sixth petition. In 2018, the CAFC upheld the PTAB’s decision with regard to the ‘940 Patent.

In 2019, the district court lifted the stay in this case. Qualcomm filed a motion for partial summary judgment in an attempt to exclude certain patents from the case, including the ‘940 Patent. The court denied this motion in January 2020. In April 2020, the court issued its claim construction order in which the court adopted our proposed construction for seven of the ten disputed terms and adopted slightly modified versions of our proposed construction for the remaining terms. Discovery in this case was closed in January 2021. Our damages expert submitted a report supporting a damages ask of $1.3 billion for Qualcomm’s unauthorized use of our technology. Such amount excludes additional amounts requested by us for interest and enhanced damages for willful infringement. Ultimately, the amount of damages, if any, will be determined by the court.

Table of Contents

Citing backlog due to the pandemic, among other factors, the court moved several scheduled deadlines in this case. Joint pre-trial statements were submitted by the parties in May 2021 and a pre-trial hearing was held in January 2022. In March 2022, the district court ruled in Qualcomm's favor on a number of motions, including summary judgment against our receiver patent claims and striking and excluding our technical expert report, essentially precluding the support of infringement testimony at trial. Accordingly, the district court closed the case and we filed an appeal with the CAFC in 2022. Oral arguments were heard by the CAFC in late 2023, and on September 6, 2024, the CAFC issued its opinion, ruling in our favor on each of the issues we appealed. The case was remanded back to the district court and reopened.

In December 2024, the district court held a status conference for the reopened case. The court denied a motion by Qualcomm for a third claim construction hearing and also denied our motion to substitute our infringement and validity expert due to medical incapacity. Both parties filed motions for reconsideration on their respective motions. In April 2025, the district court granted, on reconsideration, the Qualcomm motion for a third claim construction briefing on two previously undisputed claim terms that were critical to the September 2024 CAFC decision. On May 30, 2025, following briefings by both parties, the district court issued a claim construction order adopting Qualcomm's proposed constructions for the two claim terms. This decision, in essence, precluded us, once again, from asserting our receiver claims in the case.

In June 2025, we filed a Rule 54(b) motion requesting that the court enter a final judgment of noninfringement on our receiver claims, based on the court's most recent claim construction, and sever and stay the remaining transmit claims in the case to allow us to immediately appeal the most recent claim construction order and avoid the inefficiency of potentially two separate trials. In August 2025, the court denied our reconsideration motion to substitute our expert, and on October 2, 2025, the court granted our Rule 54(b) motion. We immediately filed an appeal with the CAFC, requesting an expedited schedule.

On October 22, 2025, the CAFC granted our motion to expedite and ordered briefings to be completed by the parties by February 2026. One day following the CAFC's expedited order, Qualcomm filed a motion to dismiss the appeal for lack of jurisdiction, temporarily suspending the court's expedited schedule. In January 2026, the CAFC again ordered an expedited schedule with briefings due to be completed by the end of March 2026 with oral arguments to be scheduled for the next available CAFC session thereafter. The CAFC's order indicated that the parties may address any jurisdictional issues in the briefs. We submitted our opening brief on February 4, 2026 which includes our position with respect to the district court's improper claim construction for our receiver patents, addresses Qualcomm's jurisdictional challenge, and also requests the CAFC reassign the case to a different district court judge. Qualcomm's response brief was filed on March 16, 2026 and our final reply brief is due to be filed on March 23, 2026.

ParkerVision v. Apple and Qualcomm (Middle District of Florida-Jacksonville Division)

We have a patent infringement case in the Middle District of Florida against Apple Inc. (“Apple”) and Qualcomm, filed in December 2015, alleging infringement of four of our patents, which was subsequently reduced to one patent. Fact discovery has closed in this case and a jury trial was scheduled to begin in August 2020. In March 2020, as a result of the impact of COVID-19, the parties filed a motion requesting an extension of certain deadlines in the case. In April 2020, the court stayed this proceeding pending the outcome of the infringement case against Qualcomm in the Orlando Division of the Middle District of Florida.

ParkerVision v. LG (District of New Jersey)

In July 2017, we filed a patent infringement complaint in the District of New Jersey against LG for the alleged infringement of four patents previously asserted against LG in the Middle District of Florida (see ParkerVision v. Apple and Qualcomm above). We elected to dismiss the case in the Middle District of Florida and re-file in New Jersey as a result of a Supreme Court ruling regarding venue. In March 2018, the court stayed this case pending a final decision in ParkerVision v. Apple and Qualcomm in the Middle District of Florida. As part of this stay, LG has agreed to be bound by the final claim construction decision in that case.

ParkerVision v. Realtek (Western District of Texas)

We filed two patent infringement actions in the Western District of Texas against Realtek Semiconductor Corp. ("Realtek"), the first in 2022 and a second in 2023, alleging infringement of an aggregate of seven of our patents. One of the seven patents was dropped from the litigation in August 2024. A claim construction hearing was held in January 2024 in the first Realtek action and the court adopted the majority of our claim constructions. A claim construction hearing was held in June 2024 in the second Realtek action, and the court again adopted the majority of our claim constructions. The two Realtek cases were scheduled for trial in January 2026 and April 2026, respectively. In December 2025, the court combined the two cases into a single trial scheduled to commence April 27, 2026, and the parties agreed to narrow the combined case to an aggregate of three patents.

ParkerVision v. TCL (Western District of Texas)

We filed two patent infringement actions in the Western District of Texas in 2020 and 2021 against TCL Industries Holdings Co., Ltd, a Chinese company, TCL Electronics Holdings Ltd., Shenzhen TCL New Technology Co., Ltd, TCL King Electrical Appliances (Huizhou) Co., Ltd., TCL Moka Int’l Ltd. and TCL Moka Manufacturing S.A. DE C.V. (collectively “TCL”) alleging infringement of approximately twelve of our patents. The court issued its claim construction recommendations in the first TCL case, adopting our claim constructions in for nearly all of the disputed terms. In January 2023, the TCL action was stayed pending final resolution of patent infringement actions filed against Realtek, the manufacturer of the integrated circuits used in TCL's alleged infringing products.

ParkerVision v. MediaTek (Western District of Texas)

We filed three patent infringement actions in the Western District of Texas against MediaTek Inc. and MediaTek USA Inc. (collectively, "MediaTek"), the first in 2022 and two additional cases in 2023, alleging infringement of an aggregate of ten of our patents. One of the patents was voluntarily dropped from the first MediaTek case in 2024 and MediaTek likewise terminated an IPR petition it had initiated against the same patent. A claim construction hearing was held in January 2024 in the first MediaTek action and the court adopted the majority of our claim constructions. A jury trial for the first MediaTek action was scheduled to commence on March 20, 2026; however, on March 16, 2026 at a pretrial conference, the court postponed the trial date pending requested updates to the expert reports and related briefings. A new trial schedule has not yet been established.

A claim construction hearing was held in June 2024 in the second MediaTek action, and the court adopted the majority of our recommended claim constructions in January 2025. The trial for the second MediaTek action had been scheduled for November 2026. However, in July 2025, the second case was stayed pending the PTAB's final written decision on IPRs impacting patents in this case. The PTAB decision was initially expected by November 2025, but the PTAB extended its deadline to May 2026.

The third MediaTek action had a claim construction hearing in June 2025 and in November 2025, the court adopted all of our proposed constructions. A trial in this third action is currently scheduled for April 2027.

ParkerVision v. LGE (Western District of Texas)

We filed a patent infringement action in the Western District of Texas against LG Electronics, a South Korean company ("LGE") in 2021, alleging infringement of ten of our patents. The court issued its claim construction recommendations in June 2022, adopting our claim constructions for nearly all of the disputed terms. In January 2023, the LGE action was stayed pending final resolution of patent infringement actions filed against Realtek and MediaTek as well as final resolution of IPR actions against patents in this case.

ParkerVision v. Texas Instruments (Western District of Texas)

We filed a patent infringement action in the Western District of Texas against Texas Instruments ("TI") in 2023, alleging infringement of three of our patents. In December 2023, TI filed a motion to change venue to the Northern District of Texas which the court denied in August 2024. A claim construction hearing was held in June 2024, and the court issued its final claim construction order in November 2024. The trial was scheduled to commence in January 2026; however in May 2025, the case was stayed pending the PTAB's final written decision on IPRs filed against all of the patents in this case (see Texas Instruments and NXP v. ParkerVision (PTAB) below).

ParkerVision v. NXP Semiconductors (Western District of Texas)

We filed a patent infringement action in the Western District of Texas against NXP Semiconductors ("NXP") in 2023, alleging infringement of three of our patents. A claim construction hearing was held in June 2024, and the court issued its final claim construction order in January 2025. A trial was scheduled to commence in February 2026; however in May 2025, the case was stayed pending the PTAB's final written decision on IPRs filed against all of the patents in this case (see Texas Instruments and NXP v. ParkerVision (PTAB) below).

TCL and LGE. v. ParkerVision (PTAB)

We appealed two IPR actions filed by TCL and LGE against our U.S. patent 7,292,835 (“the ‘835 Patent”) and U.S. patent 7,110,444, both of which are asserted in the infringement cases against these parties in the Western District of Texas. In November 2022, the PTAB issued its written decision ruling that the challenged claims for both patents were unpatentable. We appealed these decisions to the CAFC and oral arguments for both appeals were presented to the CAFC on June 3, 2024. On June 5, 2024, the CAFC issued its final decisions, in the form of Rule 36 decisions, affirming the PTAB rulings. On November 4, 2024, we submitted a petition for a Writ of Certiorari with the U.S. Supreme Court challenging the CAFC's use of Rule 36 to affirm PTAB decisions without a written opinion. On March 24, 2025, the Supreme Court denied our petition.

MediaTek v. ParkerVision (PTAB)

MediaTek filed an IPR petition in November 2023 against the ‘835 Patent which is one of the patents asserted in the first MediaTek infringement action. In May, 2024, the PTAB instituted the IPR petition. MediaTek withdrew its petition and the IPR was terminated in September 2024, following our dismissal of the '835 Patent from the patent infringement action against MediaTek. MediaTek filed a second petition for IPR in May 2024 against one of the patents asserted in the second MediaTek infringement action. The PTAB instituted this IPR in November 2024 and a final decision was expected in November 2025. In November 2025, the PTAB extended its statutory deadline to May 2026. In October 2024, MediaTek filed a third petition for IPR against one of the patents asserted in the third MediaTek action. The PTAB instituted the IPR in March 2025 and oral arguments were heard in January 2026. A final written decision is currently expected in March 2026, barring any extensions by the PTAB.

Texas Instruments and NXP v. ParkerVision (PTAB)

Texas Instruments filed three petitions for IPR in May 2024 against each of the patents asserted in the TI action. All three IPRs were instituted by the PTAB in November 2024 and a decision was expected by November 2025. NXP filed petitions for IPR against two of the three patents asserted in the NXP action, which are the same as two of the patents asserted in the TI action. Accordingly, in December 2024, the PTAB granted NXP's joinder motion to join the TI petitions. In November 2025, the PTAB issued its final written decision in one of the IPRs filed by TI, deeming our challenged patent claims to be unpatentable. We filed a request for review of this decision by the U.S. Patent and Trademark Office director and that request is currently pending. The PTAB extended its deadlines with respect to the two joint TI/NXP IPRs until May 2026.

Realtek v. ParkerVision (PTAB)

In December 2024, Realtek filed petitions for IPR against two patents asserted in the second Realtek action, which are the same as the two patents under joint IPR by TI and NXP. Realtek also filed a joinder motion to join the TI/NXP proceedings. In June 2025, the PTAB granted our request for discretionary denial and terminated both petitions as Realtek was time-barred from filing a petition more than one year following the filing of our infringement complaint.

Goldberg Segalla v. ParkerVision (Arbitration)

The law firm of Goldberg Segalla, LLP ("Goldberg") was engaged by us in 2019, on a full contingency basis, to prosecute our patent infringement actions in the Western District of Texas. In 2021, the Goldberg legal team handling all of our Texas actions left Goldberg and formed a new law firm, Daignault Iyer, LLP ("DI"). In late April 2021, we engaged DI, on a full contingency basis, to continue the prosecution of our patent infringement actions in Texas. In November 2024, Goldberg filed a demand for arbitration against us, alleging that we owe Goldberg an aggregate of $4.3 million plus costs and interest for contingency fees, disbursements and other advances. The arbitration was temporarily stayed while the parties attempted to reach a mutual agreement through mediation. Following the failure to reach an agreement, the arbitration resumed and we filed our answer to the arbitration demand in January 2026 denying Goldberg's allegations and asserting numerous affirmative defenses. We have been indemnified by both DI and Brickell for the Goldberg claims. In addition, we have an aggregate of approximately $0.8 million that has been accrued in our consolidated financial statements since 2020 for amounts that we deem the maximum amount probable of owing to Goldberg.

13. STOCK AUTHORIZATION AND ISSUANCE

Preferred Stock

We have 15 million shares of preferred stock authorized for issuance at the direction of our board of directors (the “Board”). On November 17, 2005, our Board designated 0.1 million shares of authorized preferred stock as the Series E Preferred Stock in conjunction with its adoption of a Shareholder Protection Rights Agreement that expired in November 2023. As of December 31, 2025, we had no outstanding preferred stock.

Common Stock

We have 225 million shares of common stock authorized for issuance as of December 31, 2025. Our shareholders approved amendments to our articles of incorporation in October 2024 increasing the number of our authorized shares of common stock from 175 million to 225 million shares.

As of December 31, 2025, we have 29.3 million shares reserved for issuance under outstanding warrants, options, and RSUs and 24.7 million shares reserved for issuance upon conversion of our outstanding convertible notes.

Shelf Registration and Registered Direct Offerings

In May 2025, we filed a shelf registration statement ("Shelf") for the offering of various securities, up to $25.0 million. The Shelf, which was declared effective May 25, 2025, is intended to provide flexibility for our future capital needs and may be used to fund working capital, capital expenditures, vendor purchases, and other capital needs. As of December 31, 2025, we have sold an aggregate of 21.2 million shares of common stock under the Shelf for gross proceeds of $4.5 million, including 4.8 million shares of common stock sold to an independent director for gross proceeds of $1.0 million (see Note 15).

Private Placements

In December 2024, we entered into securities purchase agreements with accredited investors for the sale of 10.0 million shares of our common stock and 2.0 million warrants at a price of $0.50 per share for aggregate gross proceeds of $5.0 million. The warrants are exercisable for a period of five years at an exercise price of $0.50 per share and have an estimated fair value of approximately $0.8 million. The shares were registered for resale on a registration statement that was declared effective on April 24, 2025 (File No. 333-286486).

Common Stock Warrants

During the year ended December 31, 2025, 5.0 million warrants with an exercise price of $0.74 per share were exercised via net share exercise, resulting in the issuance of 1.3 million shares of our common stock. In addition, during the year ended December 31, 2025, 0.4 million warrants with an exercise price of $0.16 per share expired unexercised. Cash received from warrant exercises for the years ended December 31, 2025 and 2024 was approximately $0 and $0.4 million, respectively.

We had outstanding warrants for the purchase of up to 4.3 million and 9.7 million shares of our common stock as of December 31, 2025 and 2024, respectively. The estimated grant date fair value of these warrants of $3.0 million and $4.0 million for the years ended December 31, 2025 and 2024, respectively, is included in shareholders’ deficit in our consolidated balance sheets. As of December 31, 2025, our outstanding warrants have an average exercise price of $1.05 per share and a weighted average remaining life of approximately 2.1 years.

14. SHARE-BASED COMPENSATION

During the year ended December 31, 2025, the compensation committee of our Board (the "Committee") authorized the modification of an aggregate of 11.65 million fully-vested, nonqualified share options held by the CEO, CFO, and three key employees. The options, which were awarded in January 2021, are exercisable at $0.54 per share and had an original expiration date of January 11, 2026. The Committee extended the expiration date of the options by five years, or until January 11, 2031. No other modifications were made to these awards. We recognized a one-time, non-cash charge to share-based compensation expense of approximately $2.5 million, representing the incremental fair value of the options as a result of the modification, based on a Black-Scholes option pricing model.

For the years ended December 31, 2025 and 2024, we recognized share-based compensation expense, including the expense recognized upon modification of awards, of approximately $3.3 million and $0.4 million, respectively. This share-based compensation expense includes in-kind consulting fees of $0.42 million and $0.09 million paid to third parties for the years ended December 31, 2025 and 2024, respectively. Share-based compensation, including in-kind consulting, is included in selling, general, and administrative expenses in our consolidated statements of comprehensive loss. As of December 31, 2025, there was $0.3 million of total unrecognized compensation cost related to all non-vested share-based compensation awards. That cost is expected to be recognized over a weighted-average period of approximately 0.7 years.

Stock Incentive Plans

2019 Long-Term Incentive Equity Plan

We adopted a long-term incentive equity plan in August 2019 that, as amended in January 2021, January 2023, and June 2025, provides for the grant of stock-based awards to employees, officers, directors, and consultants, not to exceed 45.0 million shares of common stock (the “2019 Plan”). The 2019 Plan provides for benefits in the form of nonqualified stock options, stock appreciation rights, restricted stock awards, and other stock-based awards that may vest over time, or based on specified performance conditions. Forfeited and expired options under the 2019 Plan become available for reissuance. The plan provides that non-employee directors may not be granted awards during any calendar year that exceed the lesser of 1.0 million shares or $175,000 in value, calculated based on grant-date fair value. At December 31, 2025, we had outstanding options for the purchase of up to 23,994,000 shares and unvested RSUs for 296,000 shares under the 2019 Plan, and we had 12,867,467 shares of common stock available for future grants under the 2019 Plan.

2011 Long-Term Incentive Equity Plan

We adopted a shareholder approved long-term incentive equity plan in September 2011 that was amended in 2014, 2016 and 2017 and provided for the grant of stock-based awards to employees, officers, directors and consultants, not to exceed 3.0 million shares of common stock (the “2011 Plan”). In January 2023, we ceased any future grants under the 2011 Plan. At December 31, 2025, we had outstanding options for the purchase of up to 175,000 shares under the 2011 Plan. Upon the exercise or expiration of these remaining outstanding options, the 2011 Plan will be terminated.

Non-Plan Awards

In addition, from time to time, we issue share-based compensation awards to third-party consultants outside of our stock incentive plans ("Non-Plan Awards"). At December 31, 2025, we had outstanding options for the purchase of up to 500,000 shares that were issued as Non-Plan Awards. The shares underlying these awards were registered for resale on a registration statement that was declared effective April 24, 2025 (File No. 333-286486).

Restricted Stock Awards

RSAs are issued as executive and employee incentive compensation and as payment for services to others. The value of the award is based on the closing price of our common stock on the date of grant. RSAs are generally immediately vested. From time to time, we issue fully vested share-based compensation awards to third parties as prepaid retainers for services over a specified period. The grant date fair value of these awards is recorded as prepaid services and expensed to selling, general and administrative expense over the service period.

Restricted Stock Units

RSUs are issued as incentive compensation to executives, employees, and non-employee directors and as payment for services to others. Each RSU represents a right to one share of our common stock, upon vesting. The RSUs are not entitled to voting rights or dividends, if any, until vested. RSUs generally vest over a one to three year period for employee awards and a one year period for non-employee director and third-party awards. The fair value of RSUs is generally based on the closing price of our common stock on the date of grant and is amortized to share-based compensation expense over the estimated life of the award, generally the vesting period. In the case of performance-based RSUs, the grant date fair value of the award is amortized to share-based compensation expense based on the probability of the performance condition being met which is assessed at each interim reporting period during the performance period for each respective award. Upon forfeiture of performance-based RSUs, any previously recognized share-based compensation expense is reversed.

Table of Contents

RSAs and RSUs

The following table presents a summary of RSA and RSU activity under the 2019 Plan and the 2011 Plan (collectively, the "Stock Plans") and Non-Plan Award activity for the year ended December 31, 2025 (shares in thousands):

	Non-vested Shares
	Shares			Weighted-Average Grant Date Fair Value
Non-vested at beginning of year		250		$	0.50
Granted		1,194			0.35
Vested		(1,048	)		0.35
Forfeited		(100	)		0.83
Non-vested at end of year		296		$	0.32

The RSAs and RSUs activity during the year ended December 31, 2025 included 100,000 performance-based RSUs granted to a third party for services with an aggregate grant date fair value of approximately $0.08 million. The performance requirements of the performance-based RSUs were not met and the award was forfeited as of December 31, 2025. The total fair value of all RSAs and RSUs vested for the years ended December 31, 2025 and 2024 was approximately $0.31 million and $0.06 million, respectively.

Stock Options

Stock options are issued as incentive compensation to executives, employees, consultants and non-employee directors. Stock options are granted with exercise prices at or above fair market value of the underlying shares at the date of grant and generally vest over a one to two year period. Fair market value of the underlying shares is determined based on observable market prices at the date of the grant. The fair value of options granted is estimated using the Black-Scholes option pricing model as of the grant date and is amortized to share-based compensation expense over the estimated life of the award, generally the vesting period. In the case of performance-based option awards, the grant date fair value of the award is amortized to share-based compensation expense based on the probability of the performance condition being met which is assessed at each interim reporting period during the performance period for each respective award. Upon forfeiture of performance-based options, any previously recognized share-based compensation expense is reversed.

Table of Contents

The following table presents a summary of option activity under the Stock Plans and Non-Plan Award activity for the year ended December 31, 2025 (shares and aggregate intrinsic value in thousands):

	Shares			Weighted- Average Exercise Price		Weighted-Average Remaining Contractual Term (in years)		Aggregate Intrinsic Value ($)
Outstanding at beginning of year		25,451		$	0.38
Granted		2,075			0.37
Exercised		(1,742	)		0.24

Vested at end of year		23,799		$	0.39		3.2	$	292

The options awarded for the year ended December 31, 2025 included 1,350,000 nonqualified performance-based options granted to third-parties for services with a weighted average exercise price of $0.31, of which 750,000 options were forfeited upon failure to meet performance conditions in 2025. Options outstanding and unvested at December 31,2025 include 600,000 performance-based options with an exercise price of $0.32 that were forfeited in January 2026 for failure to meet performance conditions.

The weighted average per share fair value of options granted during the years ended December 31, 2025 and 2024 was $0.30 and $0.23, respectively. The total fair value of options vested was $0.4 million and $0.3 million for the years ended December 31, 2025 and 2024, respectively.

The fair value of option grants for the years ended December 31, 2025 and 2024, respectively, was estimated using the Black-Scholes option-pricing model with the following assumptions:

	Year ended December 31,
	2025	2024
Expected option term (in years) ¹	2-5	5
Expected volatility factor ²	126.8% - 150.6%	150.6%
Risk-free interest rate ³	3.82% - 4.26%	3.80%
Expected annual dividend yield	0%	0%

¹ The expected term was generally determined based on historical activity for grants with similar terms and for similar groups of employees and represents the period of time that options are expected to be outstanding. For employee options, groups of employees with similar historical exercise behavior are considered separately for valuation purposes. For third parties, the expected term is estimated to be the contractual life of the related service agreement.

² The stock volatility for each grant is measured using the weighted average of historical daily price changes of our common stock over the most recent period equal to the expected option term.

³ The risk-free interest rate for periods equal to the option expected term is based on the U.S. Treasury yield curve in effect at the measurement date.

We issue new shares of our common stock upon exercise of options or vesting of RSUs or RSAs. All of the shares underlying the Stock Plans as well as the Non-Plan Awards are registered. Cash received from option exercises for the years ended December 31, 2025 and 2024, was $0.43 million and $0.34 million, respectively.

15. RELATED PARTY TRANSACTIONS

On November 17, 2025, we closed the sale of approximately 4.8 million shares of common stock at a price of $0.21 per share to an independent director for gross proceeds of $1.0 million. The $0.21 per share price represents the last sale price ParkerVision’s common stock on November 14, 2025, as reported by the OTCQB Venture Market. The stock was sold in a registered direct offering under the Company’s Shelf (see Note 13).

On May 10, 2024, we amended convertible notes held by two of our independent directors. A June 19, 2019 note with a principal balance of $0.03 million and a September 13, 2019 note with a principal balance of $0.05 million were amended to extend the maturity dates to March 15, 2026, reduce the interest rate from 8% to 5% and to replace the quarterly interest payments with a single payment of unpaid, accrued interest at the earlier of conversion or maturity of the notes. Additional convertible notes with an aggregate principal balance of $0.48 million were also amended to replace the quarterly interest payment dates with a single payment of unpaid, accrued interest at the earlier of conversion or maturity of the notes. These additional amended notes include a $0.05 million convertible note dated January 8, 2020, $0.3 million in convertible notes dated May 10, 2022, and a $0.1 million convertible note dated September 15, 2023. Notes held by independent directors with an aggregate face value of $0.2 million and $0.33 million, respectively, were converted during the years ended December 31, 2025 and 2024. At December 31, 2025, no convertible notes were held by our directors.

We paid approximately $0.04 million in each of the years ended December 31, 2025 and 2024 for patent-related legal services to SKGF, of which one of our independent directors is a partner. In addition, we paid approximately $0.2 million for principal and interest on a note payable to SKGF during each of the years ended December 31, 2025 and 2024 (see Note 7). The note payable to SKGF has an outstanding balance, including accrued interest, of approximately $0.2 million at December 31, 2025.

16. CONCENTRATIONS OF CREDIT RISK

Financial instruments that potentially subject us to a concentration of credit risk consist of cash and cash equivalents that are primarily held in bank accounts and overnight investments. We are exposed to credit risk from time to time, subject to federal deposit insurance, in the event of default by the financial institution holding our cash and cash equivalents. We had no cash and cash equivalents held in excess of federally insured limits at December 31, 2025. The cash and cash equivalents in deposit accounts held in excess of federally insured limits was $2.1 million at December 31, 2024 following our closing of an equity-based transaction on December 30, 2024. We mitigate this risk by depositing our cash and cash equivalents with major financial institutions and by ensuring timely transfers of excess funds to a high-yield savings program that offers federal insurance protection through a network of financial institutions.

17. SEGMENT INFORMATION

Our operations constitute a single reportable segment, focused on licensing our innovative, fundamental wireless technologies, often through patent infringement enforcement actions. All revenues, operating expenses and assets attributable to this segment are reflected in the consolidated financial statements.

Item 9A. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

Under Rules 13a-15(e) and 15d-15(e) of the Exchange Act, “disclosure controls and procedures” are controls and other procedures that are designed to ensure that the information we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified under the rules and forms of the SEC. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that such information is accumulated and communicated to our management, including our chief executive officer and our chief financial officer, as appropriate to allow timely decisions regarding required disclosures. Our management, with the participation of our chief executive officer and our chief financial officer, has evaluated the effectiveness of our disclosure controls and procedures as of December 31, 2025. Based on such evaluation, our chief executive officer and our chief financial officer have concluded that as of December 31, 2025, our disclosure controls and procedures were effective.

Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting and for the assessment of the effectiveness of internal control over financial reporting. Under Rules 13a-15(f) and 15d-15(f) of the Exchange Act, “internal control over financial reporting’’ is defined as a process designed by, or under the supervision of, our chief executive officer and our chief financial officer, and effected by our Board, management and other personnel, to provide reasonable assurance regarding the reliability of our financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.

Internal control over financial reporting includes policies and procedures that pertain to the maintenance of records, that in reasonable detail, accurately and fairly reflect our transactions and our dispositions of assets; provide reasonable assurance that transactions are recorded as necessary to permit preparation of our financial statements in accordance with generally accepted accounting; provide reasonable assurance that receipts and expenditures of the Company are made only in accordance with authorizations of management and directors; and provide reasonable assurance regarding the prevention or the timely detection of the unauthorized acquisition, use or disposition of the Company’s assets that could have a material effect on our financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies and procedures may deteriorate.

Management, with the participation of our chief executive officer and our chief financial officer, conducted an evaluation of the effectiveness of our internal control over financial reporting as of December 31, 2025 using the criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission in 2013. Based on this evaluation, management concluded that our internal control over financial reporting was effective as of December 31, 2025.

Item 11. Executive Compensation.

Summary Compensation Table

The following table summarizes the total compensation of each of our “named executive officers” as defined in Item 402(m) of Regulation S-K (the “Executives”) for the fiscal years ended December 31, 2025 and 2024. Given the complexity of disclosure requirements concerning executive compensation, and in particular with respect to the standards of financial accounting and reporting related to equity compensation, there is a difference between the compensation that is reported in this table versus that which is actually paid to and received by the Executives. The amounts in the Summary Compensation Table that reflect the full grant date fair value of an equity award, do not necessarily correspond to the actual value that has been realized or will be realized in the future with respect to these awards.

Narrative to Summary Compensation Table

Base Salaries and Discretionary Bonuses

The base salaries of our named executive officers, and other key employees, were reduced by approximately 20%, on a voluntary basis, in September 2018 in connection with significant cost reduction measures. Until April 2025, base salaries were maintained at those reduced levels. From time to time, our compensation committee awarded discretionary cash and/or equity-based bonuses that took into consideration these continued base salary reductions as well as the individual's performance and contribution to the corporate goals.

In January 2025, our compensation committee approved the payment of discretionary cash bonuses for Mr. Parker and Ms. French in the amounts of $350,000 and $100,000, respectively. These bonuses were awarded in recognition of the officers' significant contribution to our strategic initiatives, including Mr. Parker's leadership in overseeing our patent litigation efforts and supporting our financial stability and Ms. French's role in maintaining compliance with regulatory requirements and reducing costs associated with outside professional services. The bonuses also partially offset the voluntary 20% base salary reductions since 2018 as part of the officers' efforts to support the Company during a period of significant challenges. The bonuses reflect the compensation committee's intent to appropriately compensate these executives for their leadership and sustained commitment to advancing the Company's goals.

Table of Contents

In April 2025, our compensation committee approved an increase in base compensation for Mr. Parker, from $260,000 to $400,000 and an increase in base compensation for Ms. French from $180,000 to $250,000. The compensation committee considered a similarly sized peer group (“Peer Group”) developed by an independent compensation consultant in its evaluation of base salaries for its named executive officers and established base compensation that fell below the 50^th percentile when compared to the Peer Group.

In January 2026, our compensation committee approved grants, under the 2019 Plan, of nonqualified performance-based stock options to Mr. Parker and Ms. French. The performance-based grants included a performance-based option to purchase up to 8,000,000 shares granted to Mr. Parker and a performance-based option to purchase up to 500,000 shares granted to Ms. French. The options have a five-year performance period, with quarterly measurement dates, and expire ten years from the date of grant. Vested options are exercisable at a price of $0.24 per share, which was the last sale price of the our common stock on the date of grant. The performance conditions for vesting of these options are based on cumulative net cash received by the company from its patent enforcement actions, after deduction of all attorney contingency fees and contractual repayments of contingent payment obligations to third parties. The performance-based options provide for automatic acceleration of vesting, regardless of performance conditions, in the event (i) the market capitalization of the company meets or exceeds $1 billion for twenty (20) consecutive trading days, or (ii) upon a change in control event. In addition, the compensation committee approved a grant to Ms. French, under the 2019 Plan, of a nonqualified time-based stock option for the purchase of up to 500,000 shares. This option has an exercise price of $0.24 per share, vests in four equal biannual installments over a two-year period beginning July 22, 2026, and expires five years from the date of grant.

Employment and Non-Compete Agreements

We do not have employment agreements in place for our executives. We do have non-compete arrangements in place with all of our employees, including our executives, that impose post-termination restrictions on (i) employment or consultation with competing companies or customers, (ii) recruiting or hiring employees for a competing company, and (iii) soliciting or accepting business from our customers.

Employee Benefits and Perquisites

Our named executive officers are eligible to participate in our health and other benefit plans to the same extent as our other full-time employees. We generally do not provide our named executive officers with perquisites or other personal benefits that are not afforded to all full-time employees, with the exception of a $24,000 annual vehicle allowance provided for our chief executive officer.

Policies and Practices Related to the Grant of Equity Awards

From time to time, we grant equity awards, including stock options, to our employees, including our named executive officers. Historically, we have typically granted new-hire option awards on a new hire's employment start date. Also, non-employee directors have historically received annual equity awards during or about the first month of each calendar year, pursuant to our non-employee director compensation policy. We do not otherwise maintain any written policies on the timing of our equity awards. Our compensation committee considers whether there is any material nonpublic information ("MNPI") about our company when determining the timing of equity awards and does not seek to time the grant of equity awards in relation to our public disclosure of MNPI. We have not timed the release of MNPI for the purpose of affecting the value of executive compensation. During the year ended December 31, 2025, we did not grant any stock option or other equity awards to our named executive officers.

In April 2025, the compensation committee approved the modification of nonqualified options held by our named executive officers in order to extend the expiration date of the options from January 11, 2026 to January 11, 2031. The modified options include 8,000,000 options awarded to the CEO and 1,000,000 options awarded to the CFO on January 11, 2021, with exercise prices of $0.54 per share and an original term of five years. The options were fully vested as of the modification date and we recorded a one-time charge to share-based compensation of approximately $1.9 million in connection with the modification of these awards. The extension of the expiration date is the only modification made to these awards and no additional securities were issued.

Independent Compensation Consultant

In December 2024, our compensation committee retained an independent consultant to conduct a competitive review and assessment of our executive compensation program and to make recommendations for both our executive compensation and non-employee director compensation programs on a going forward basis.

²	Options vested over eight equal quarterly periods from March 31, 2021 to December 31, 2022 and were amended in April 2025 to extend the expiration date from January 11, 2026 to January 11, 2031.

³	Options vested 50% on grant date and the remaining 50% over four equal quarterly periods from May 9, 2020 to May 9, 2021.

⁴	Number of securities underlying exercisable options is net of 3.3 million share options gifted for no consideration by Mr. Parker in January 2021.

Director Compensation

Since September 2018, the Board compensation program has consisted exclusively of equity-based compensation, generally awarded annually, in the form of nonqualified stock options, RSUs, or a combination thereof. Unvested director equity compensation awards are forfeited if the director's services are terminated for any reason. In January 2023, the Board formalized its non-employee director compensation program whereby (i) non-employee directors will continue to solely receive share-based compensation for board and committee service, (ii) share-based compensation will be awarded annually on or about the first month of each year, (iii) the grant-date fair value of non-employee director awards for annual board service shall not exceed $80,000 for board service and no more than $20,000 additional for service on board committees, (iv) the awards shall vest over one year and expire no more than seven years after grant date, and (v) any unvested awards shall be forfeited upon a director's termination of service for any reason.

In January 2025, the compensation committee delayed its annual non-employee director compensation awards pending review of a report from a third-party compensation consultant on independent director compensation. On July 3, 2025, each of our non-employee directors were awarded, at their discretion, either (i) 275,000 restricted share units (“RSUs”) or (ii) 300,000 nonqualified share options with an exercise price of $0.29 per share for 2025 director compensation. The awards vested 50% upon grant and 50% on December 31, 2025. Each of the director awards has a grant-date fair value of approximately $80,000 which aligned with the independent compensation consultant recommendations.

Table of Contents

On January 22, 2026, each of our non-employee directors were awarded 370,000 nonqualified share options with an exercise price of $0.24 per share for 2026 director compensation. The awards vest in two bi-annual installments beginning July 22, 2026. Each of the director awards has a grant-date fair value of approximately $76,000.

We reimburse our non-employee directors for their reasonable expenses incurred in attending meetings where applicable and we encourage participation in relevant educational programs for which we reimburse all or a portion of the costs incurred for these purposes.

Directors who are also our employees are not compensated for serving on our Board. Information regarding compensation otherwise received by our directors who are also named executive officers is provided under “Executive Compensation.”

Item 13. Certain Relationships and Related Transactions and Director Independence.

Related Party Transactions

On November 17, 2025, we sold 4,761,905 shares of common stock at a price of $0.21 per share to Mr. Lewis Titterton, for gross proceeds of $1,000,000. The $0.21 per share price represents the last sale price ParkerVision’s common stock on November 14, 2025, as reported by the OTCQB Venture Market. The stock was sold in a registered direct offering under our Shelf that was declared effective by the Securities and Exchange Commission on May 28, 2025.

From time to time, we have sold convertible notes to accredited investors, including certain of our directors (see Note 8). Mr. Lewis Titterton, prior to becoming a director in June 2023, purchased an aggregate of $425,000 in convertible notes from us, with conversion prices ranging from $0.10 to $0.40 per share and maturity dates ranging from September 2023 to May 2027. On May 10, 2024, we amended two convertible notes issued in 2019 with an aggregate principal balance of $75,000 to extend the maturity dates to March 2026, reduce the stated interest rate from 8% to 5%, and replace the quarterly interest payments with a single payment of unpaid, accrued interest at the earlier of conversion or maturity of the notes. We also amended a $50,000 note issued in 2020 and a $200,000 note issued in 2022 to Mr. Titterton to likewise replace the quarterly interest payments with a single, lump sum payment upon conversion or maturity. In September 2024, Mr. Titterton converted an aggregate of $125,000 in notes issued in 2019 and 2020 into shares of our common stock. In May 2025, Mr. Titterton converted his remaining $200,000 in notes into shares of our common stock. At December 31, 2025, Mr. Titterton holds no outstanding convertible notes.

On May 10, 2024, we amended the convertible notes held by Mr. Paul Rosenbaum to defer the payment of interest until the earlier of maturity or conversion. In October 2024, Mr. Rosenbaum converted all of his outstanding notes into shares of our common stock.

We paid approximately $42,000 and $39,000 in 2025 and 2024, respectively, for patent-related legal services to SKGF, of which Robert Sterne is a partner. In addition, we paid approximately $150,000 in both 2025 and 2024 for principal and interest on the SKGF Note (see Note 7). The SKGF Note has an outstanding balance, including accrued interest, of approximately $201,000 at December 31, 2025.

We follow the rules of Nasdaq in determining if a director is independent. The Board also consults with our counsel to ensure that the Board’s determination is consistent with those rules and all relevant securities and other laws and regulations regarding the independence of directors. The Board has affirmatively determined that Messrs. Titterton, Rosenbaum, and Sterne are independent directors.
