NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)     1. Description of Business   ParkerVision, Inc. and its wholly-owned German subsidiary, ParkerVision GmbH (collectively “ParkerVision”, “we” or the “Company”), is in the business of innovating fundamental wireless hardware technologies and products.   We have designed and developed proprietary radio frequency (“RF”) technologies and integrated circuits based on those technologies, and we license those 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.     2. Liquidity and Going Concern   For the three months ended March 31, 2023 , we recognized net income of approximately $ 13.1 million and cash flows from operations of approximately $ 13.2 million.  At March 31, 2023 , we had cash and cash equivalents, excluding restricted cash, of approximately $ 0.1 million and an accumulated deficit of approximately $ 430.1 million.  We had restricted cash of approximately $ 13.9 million at March 31, 2023, all of which was used to make a repayment on our secured contingent payment obligation in May 2023.      For the three months ended March 31, 2023 , we received aggregate net proceeds from debt and equity financings of approximately $ 0.8 million. On May 4, 2023, we entered into a confidential letter agreement with Brickell whereby Brickell provided $ 5.0 million in new funding to us on substantially similar repayment terms as those set forth in our existing contingent payment agreement, but at a lower interest rate.   These proceeds will be used to support our operations.  We believe our current capital resources are sufficient to meet our liquidity needs for at least the next twelve months and we will not be required to seek additional capital.     We expect to continue to invest in the support of our patent licensing and enforcement program.  A significant amount of future proceeds that we may receive from our patent licensing and enforcement program will be first utilized to repay borrowings and legal fees and expenses under our contingent funding arrangements.  The long-term continuation of our business plan is dependent upon the generation of sufficient cash flows from our technologies and/or products 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 will have a material adverse effect on our ability to meet our long-term liquidity needs and achieve our intended long-term business objectives.   6 Table of Contents     3. Basis of Presentation   The accompanying unaudited condensed consolidated financial statements for the period ended March 31, 2023 were prepared in accordance with generally accepted accounting principles (“GAAP”) for interim financial information and with the instructions to Form 10 -Q and Rule 10 - 01 of Regulation S- X.   Operating results for the three months ended March 31, 2023 , are not necessarily indicative of the results that may be expected for the year ending December 31, 2023 , or future years.  All normal and recurring adjustments which, in the opinion of management, are necessary for a fair statement of the consolidated financial condition and results of operations have been included.   The year-end condensed consolidated balance sheet data was derived from audited financial statements for the year ended December 31, 2022 .  Certain information and disclosures normally included in the notes to the annual financial statements prepared in accordance with GAAP have been omitted from these interim condensed consolidated financial statements.  These interim condensed consolidated financial statements should be read in conjunction with our latest Annual Report on Form 10 -K for the year ended December 31, 2022 (“ 2022 Annual Report”).   The condensed consolidated financial statements include the accounts of ParkerVision, Inc. and its wholly-owned German subsidiary, ParkerVision GmbH, after elimination of all intercompany transactions and accounts.       4. Accounting Policies   There have been no changes in accounting policies from those stated in our 2022 Annual Report.  We do not expect any newly effective accounting standards to have a material impact on our financial position, results of operations or cash flows when they become effective.      5. Revenue   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.  We recognize such payments as revenue in accordance with Accounting Standards Codification (“ASC”) 606, “Revenue from Contracts with Customers.”   We recognized $ 25.0 million of revenue during the three -month period ended March 31, 2023 from patent license and settlement agreements with third parties for their use of our technologies.  Our performance obligations were satisfied, and therefore revenue recognized, upon transfer of the licensed rights and dismissal of all patent enforcement actions between the parties.  No revenue was recognized during the three months ended March 31, 2022 .    7 Table of Contents     6. Earnings per Common Share   Basic earnings per common share is determined based on the weighted-average number of common shares outstanding during each period.    The dilutive effect of outstanding options and warrants is calculated using the treasury stock method.  The dilutive effect of shares underlying convertible notes was calculated using the if-converted method.   The following table shows the computation of basic and diluted earnings per share for the  three months ended March 31, 2023 and 2022 (net income and shares in thousands):       March 31,       2023     2022   Numerator                 Net income   $ 13,115     $ 332   Effect of dilutive securities     99       56   Net income adjusted for dilutive effect     13,214       388                     Denominator:                 Weighted-average basic shares outstanding     83,968       77,553   Effect of dilutive securities     37,728       28,919   Weighted-average diluted shares     121,696       106,472                     Basic earnings per share   $ 0.16     $ 0.00   Diluted earnings per share   $ 0.11     $ 0.00     Diluted earnings per common share for the  three months ended March 31, 2023 and 2022 excludes options and warrants that are anti-dilutive.  The anti-dilutive common share equivalents at  March 31, 2023 and 2022 were as follows (in thousands):       March 31,       2023     2022   Options outstanding     17,526       13,413   Warrants outstanding     7,346       7,346         24,872       20,759     8 Table of Contents     7. Cash, Cash Equivalents and Restricted Cash   Cash, cash equivalents and restricted cash of $ 14.06 million as of March 31, 2023, consists of $ 0.135 million of cash and cash equivalents and $ 13.925 million in restricted cash.  Restricted cash represents cash held in escrow by our attorneys designated for repayment of principal on our secured contingent debt obligation.  These restricted funds were released from escrow and remitted to Brickell in May 2023.        8. Prepaid Expenses   Prepaid expenses consist of the following (in thousands):       March 31, 2023     December 31, 2022   Prepaid services   $ 185     $ 202   Prepaid insurance     24       25   Prepaid licenses, software tools and support     15       15   Other prepaid expenses     2       2       $ 226     $ 244     Prepaid services at March 31, 2023 and December 31, 2022 include approximately $ 0.2 million and $ 0.2 million, respectively of consulting services paid in shares of stock or warrants to purchase shares of stock in the future.     9. Intangible Assets   Intangible assets consist of the following (in thousands):       March 31, 2023     December 31, 2022   Patents and copyrights   $ 14,216     $ 14,319   Accumulated amortization     ( 12,964 )     ( 12,960 )     $ 1,252     $ 1,359     9 Table of Contents     10. Debt   Related Party Note Payable   We have an unsecured promissory note of approximately $ 0.6 million payable to Sterne, Kessler, Goldstein, & Fox, PLLC (“SKGF”), a related party, for outstanding unpaid fees for legal services.  In 2022 , SKGF agreed to amend the note in order to change and extend the final balloon payment due under the note from April 2023 to April 2027.  The SKGF note, as amended, will continue to accrue interest at a rate of 4 % per annum, requires monthly payments of principal and interest of $ 12,500 with a final balloon payment of approximately $ 0.02 million in  April 2027.  We are currently in compliance with all the terms of the note.    Convertible Notes   Our convertible notes represent 5 -year promissory notes that are convertible, at the holders’ option, into shares of our common stock at fixed conversion prices.  Interest payments are made on a quarterly basis and are payable, at our option, 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.  To date, 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 condensed consolidated financial statements.   We have the option to prepay the majority 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 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 principal balance of the notes.   For the three months ended March 31, 2023 , convertible notes with a face value of $ 0.2 million were converted, at the option of the holder, into approximately 1.5 million shares of our common stock.  For the three months ended March 31, 2023 , we recognized interest expense of approximately $ 0.1 million related to the contractual interest on our convertible notes which we elected to pay in shares of our common stock and issued approximately 428,000 shares of our common stock as interest-in-kind payments.   In January 2023, we issued 5 -year convertible notes with an aggregate face value of $ 0.7 million to accredited investors.  The notes have a conversion price of $ 0.16 per share.  The shares underlying the notes, as well as shares reserved for future in-kind interest payments on the notes, were registered on a registration statement that was declared effective on May 11, 2023 ( File No. 333 -

Fair Value Measurements   The following tables summarize the fair value of our contingent payment obligations measured at fair value on a recurring basis as of March 31, 2023 and December 31, 2022 (in thousands):               Fair Value Measurements       Total Fair Value     Quoted Prices in Active Markets (Level 1)     Significant Other Observable Inputs (Level 2)     Significant Unobservable Inputs (Level 3)   March 31, 2023:                                 Liabilities:                                 Secured contingent payment obligation   $ 38,903     $ -     $ -     $ 38,903   Unsecured contingent payment obligations     6,545       -       -       6,545                 Fair Value Measurements       Total Fair Value     Quoted Prices in Active Markets (Level 1)     Significant Other Observable Inputs (Level 2)     Significant Unobservable Inputs (Level 3)   December 31, 2022:                                 Liabilities:                                 Secured contingent payment obligation   $ 40,708     $ -     $ -     $ 40,708   Unsecured contingent payment obligations     5,089       -       -       5,089     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 of  17.94 % at March 31, 2023 , based on a risk-free rate of  3.94 % as adjusted by  8 % for credit risk and  6 % for litigation inherent risk.   The following table provides quantitative information about the significant unobservable inputs used in the measurement of fair value for both the secured and unsecured contingent payment obligations at March 31, 2023 , 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.       Secured Contingent Payment Obligation     Unsecured Contingent Payment Obligations   Unobservable Inputs   Low     Weighted Average     High     Low     Weighted Average     High                                                     Estimated undiscounted cash outflows (in millions)   $ 13.9     $ 58.9     $ 102.9     $ -     $ 9.7     $ 10.8   Duration (in years)     0.3       2.4       4.3       0.8       2.1       4.3   Estimated probabilities     5 %     20 %     35 %     5 %     22 %     35 %   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.   13 Table of Contents     12. 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.   ParkerVision v. Qualcomm (Middle District of Florida-Orlando Division) - Appealed to U.S. Court of Appeals for the Federal Circuit We have appealed certain  March 2022 rulings by the Middle District of Florida in our patent infringement complaint against Qualcomm Incorporated and Qualcomm Atheros, Inc. (collectively “Qualcomm”).  Appellate court briefs have been filed by both parties and we are awaiting a hearing date in this matter.    The patent infringement case was filed in the Middle District of Florida in May 2014.  The case was stayed in February 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 March 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 September 2018, the Federal Circuit upheld the PTAB's decision with regard to the '940 Patent and, in January 2019, the court lifted the stay in this case.  In July 2019, the court issued an order that granted our proposed selection of patent claims from four asserted patents, including the '940 Patent, and denied Qualcomm's request to limit the claims and patents.  The court also agreed that we may elect to pursue accused products that were at issue at the time the case was stayed, as well as new products that were released by Qualcomm during the pendency of the stay.  In September 2019, 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.  Due to the impact of COVID- 19, a number of the scheduled deadlines in this case were moved, including the trial commencement date which was rescheduled from December 2020 to May 2021.  In October 2020, our damages expert submitted a report supporting our 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.  Discovery was expected to close in December 2020; however, the court allowed us to designate a substitute expert due to medical issues with one of our experts in the case.  Accordingly, the close of discovery was delayed until January 2021.  As a result of these delays, the court rescheduled the trial commencement date from May 3, 2021 to July 6, 2021.   In March 2021, the court further delayed the trial date citing backlog due to the pandemic, among other factors.  A new trial date was not set and the court indicated the case was unlikely to be tried before November or December 2021.  Fact and expert discovery was completed, expert reports were submitted, and summary judgment and Daubert briefings were submitted by the parties.  Joint pre-trial statements were submitted in May 2021.  In March 2021, the court granted Qualcomm's motion to strike certain of our 2020 infringement contentions.  As a result of this ruling, in July 2021, we filed a joint motion for entry of a judgment of non-infringement of our Patent No. 7,865,177 ("the '177 Patent"), subject to appeal.   14 Table of Contents   In January 2022, the court held a hearing to allow the parties to present their respective positions on three outstanding motions.  The court indicated that upon its ruling on these motions, a pre-trial conference would be scheduled and a trial date set.  On March 9, 2022, the court ruled with respect to one of these motions granting Qualcomm’s motion to strike and exclude opinions regarding the alleged infringement and validity issues.  This court order precluded the presentation of infringement and validity opinions by both of our experts at trial. On March 22, 2022, the court issued an order granting Qualcomm’s motion for summary judgment ruling that Qualcomm does not infringe the remaining three patents in this case.  On April 20, 2022, we filed a notice of appeal to the United States Court of Appeals for the Federal Circuit.  As a result of the court’s summary judgment motion in favor of Qualcomm, Qualcomm has the right to petition the court for its fees and costs. The court has granted a Qualcomm motion to delay such a petition until 30 days following the appellate court’s decision.  We are represented in this case on a full contingency fee basis.   ParkerVision v. Apple and Qualcomm (Middle District of Florida-Jacksonville Division) In December 2015, we filed a patent infringement complaint in the Middle District of Florida against Apple Inc. (“Apple”), LG Electronics, Inc., LG Electronics U.S.A., Inc. and LG Electronics MobileComm U.S.A., Inc. (collectively “LG”), Samsung Electronics Co. Ltd., Samsung Electronics America, Inc., Samsung Telecommunications America LLC, and Samsung Semiconductor, Inc. (collectively “Samsung”), and Qualcomm alleging infringement of  four  of our patents.  In February 2016, the district court proceedings were stayed pending resolution of a corresponding case filed at the International Trade Commission (“ITC”).  In July 2016, we entered into a patent license and settlement agreement with Samsung and, as a result, Samsung was dismissed from the district court action.  In March 2017, we filed a motion to terminate the ITC proceedings and a corresponding motion to lift the stay in the district court case. This motion was granted in May 2017. In July 2017, we filed a motion to dismiss LG from the district court case and re-filed our claims against LG in the District of New Jersey (see ParkerVision v. LG below).  Also in July 2017, Qualcomm filed a motion to change venue to the Southern District of California, and Apple filed a motion to dismiss for improper venue. In March 2018, the district court ruled against the Qualcomm and Apple motions. The parties also filed a joint motion in March 2018 to eliminate  three  of the  four  patents in the case in order to expedite proceedings leaving our U.S. patent 9,118,528 as the only remaining patent in this case.  A claim construction hearing was held on August 31, 2018. In July 2019, the court issued its claim construction order in which the court adopted our proposed claim construction for  two  of the  six  terms and the “plain and ordinary meaning” on the remaining terms. In addition, the court denied a motion filed by Apple for summary judgment.  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, which is currently pending an appeal.     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 the same 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 proper 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. Intel (Western District of Texas) In February 2020, we filed a patent infringement complaint in the Western District of Texas against Intel Corporation (“Intel”) alleging infringement of eight of our patents. The complaint was amended in May 2020 to add two additional patents. In June 2020, we requested that one of the patents be dropped from this case and filed a second case in the Western District of Texas that included this dismissed patent (see ParkerVision v. Intel II below). Intel’s response to our complaint was filed in June 2020 denying infringement and claiming invalidity of the patents. Intel also filed a motion to transfer venue which was denied by the court.  In July 2020 and September 2020, Intel filed petitions for Inter Partes Review (“IPR”) against two of the patents in this case and in January 2021, the PTAB instituted proceedings with regard to these two petitions (see Intel v. ParkerVision (PTAB) below).   15 Table of Contents   The court issued its claim construction ruling in January  2021  in which the majority of the claims were decided in our favor.  The case was scheduled for trial beginning February 7, 2022.  In April 2021, we filed an amended complaint to include additional Intel semiconductors and products, including WiFi devices, to the complaint.  The court suggested that, given the number of patents at issue, the case would be separated into two trials and, as a result of the added products, the first trial date was scheduled for June 2022.   In January 2022, the PTAB issued its ruling on the IPRs (see Intel v. ParkerVision (PTAB) below).  In February 2022, the parties filed a joint motion with respect to both Intel cases whereby the first case would be narrowed to six total patents asserted against Intel cellular products.  These same six patents would be also asserted in the second Intel case, along with one additional patent from the second case, against Intel WiFi and Bluetooth products.  As a result of the restructuring of the two cases, the trial date was moved to October 2022.  In March 2022, due to discovery delays, the court agreed to move the trial commencement date to December 5, 2022.  In March 2022, Intel filed a motion requesting further claim construction which we opposed and the court denied.  In May 2022, we filed a motion to amend our complaint to add willful infringement based on information obtained during discovery.  The court granted this motion in June 2022 and we filed an amended complaint. As a result of additional discovery allowed by the court, the trial date was rescheduled from December 5, 2022 to February 6, 2023.    Beginning in November 2022, the parties filed a number of pre-trial motions.  The court held hearings on these pre-trial motions in January 2023.  The court issued its written orders with regard to these motions immediately prior to the February 6, 2023 trial start date.  As a result of the court's pre-trial rulings, the potential damages in the case decreased significantly.  On February 7, 2023, the parties resolved their outstanding dispute and we have dismissed all pending actions against Intel.   ParkerVision v. Intel II (Western District of Texas) In June 2020, to reduce the number of claims in ParkerVision v. Intel , we filed a second patent infringement complaint in the Western District of Texas against Intel that included one patent that we voluntarily dismissed from the original case.  In July 2020, we amended our complaint adding two more patents to the case.  Intel responded to the complaint denying infringement and claiming invalidity of the patents.  In January 2021, Intel filed a petition for IPR against one of the patents in this case and in July 2021, the PTAB instituted proceedings with regard to this petition (see Intel v. ParkerVision (PTAB) below).  We filed an amended complaint in 2021 adding Intel WiFi and Bluetooth products to the case.  Two claim construction hearings were held in June 2021 and July 2021 and the court’s claim construction ruling was largely decided in our favor.  The case was scheduled for trial in October 2022.  In February 2022, the parties filed a joint motion which provided that the Intel II case would assert the same six patents from the first Intel case, provided none of the patents were invalidated in the first case, as well as one additional patent, depending on the outcome of the pending IPR proceeding.  On February 7, 2023, the parties resolved their outstanding dispute and we have dismissed all pending actions against Intel.   Intel v. ParkerVision (PTAB) Intel filed IPR petitions against U.S. patent 7,539,474 (“the ‘474 Patent”) and U.S. patent 7,110,444 (“the ‘444 Patent”) which were both asserted in ParkerVision v. Intel .  Intel also filed a petition for IPR against U.S. patent 8,190,108 (“the ‘108 Patent”), which is asserted in ParkerVision v. Intel II . In January 2021, the PTAB issued its decision to institute IPR proceedings for the ‘444 Patent and the ‘474 Patent.  An oral hearing was held on November 1, 2021 and final decisions from the PTAB on the ‘474 Patent and the ‘444 Patent were issued in January 2022.  The PTAB ruled against us with respect to the single challenged claim of the ’444 Patent and ruled in our favor with respect to the seven challenged claims of the ‘474 Patent.  The ‘444 Patent has subsequently been excluded from the narrowed claims asserted in ParkerVision v. Intel .  In July 2022, we appealed the PTAB decision on the '444 Patent to the Federal Circuit.    In July 2021, the PTAB issued its decision to institute IPR proceedings for the ‘108 Patent.  We filed our response to this petition in October 2021 and an oral hearing was scheduled for April 2022.  A final decision from the PTAB was issued in June 2022 in which the PTAB ruled against us with respect to all of the challenged claims of the ‘108 Patent.  We filed a notice of appeal with the Federal Circuit with respect to this IPR decision.  Following the parties' resolution of outstanding disputes (see ParkerVision v. Intel above), Intel withdrew as a party to these appeals. The U.S. Patent and Trademark Office ("USPTO") has exercised its right to intervene following Intel's withdrawal and defend the PTAB's decisions.    16 Table of Contents   Additional Patent Infringement Cases – Western District of Texas ParkerVision filed a number of additional patent cases in the Western District of Texas in 2020 including cases against (i) 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”), (ii) Hisense Co., Ltd. and Hisense Visual Technology Co., Ltd (collectively “Hisense”), a Chinese company, (iii) Buffalo Inc., a Japanese company (“Buffalo”) and (iv) Zyxel Communications Corporation, a Chinese multinational electronics company headquartered in Taiwan, (“Zyxel”).  Each case alleges infringement of the same  ten  patents by products that incorporate modules containing certain WiFi semiconductors manufactured by Realtek and/or MediaTek.  In May 2021, a case alleging infringement of the same ten patents was filed against LG Electronics, a South Korean company ("LGE").  Each of the defendants have filed responses denying infringement and claiming invalidity of the patents, among other defenses.  A second case was filed against Hisense in June 2021 alleging infringement of two additional patents and a second case was filed against TCL in November 2022 alleging infringement of the same two additional patents.    In November 2022, patent infringement actions were also filed against Taiwanese companies, Realtek Semiconductor Corp. ("Realtek") and MediaTek Inc. and MediaTek USA Inc. (collectively, "MediaTek") for infringement of four U.S. patents that are included in other Texas cases.   We dismissed the actions against Buffalo and Zyxel in 2021 following satisfaction of the parties' obligations under patent license and settlement agreements.  In November 2022, we dismissed the two cases against Hisense following satisfaction of the parties' obligations under a patent license and settlement agreement.   The court has issued claim construction recommendations for the TCL and LGE cases, in which nearly all of the claim terms were decided in our favor.  In November 2022, the PTAB issued its written decision in two IPRs asserted by TCL and LGE against two of the patents asserted against them (see TCL, et. al. v. ParkerVision (PTAB) below.    In January 2023, the cases against TCL were stayed pending final resolution of the Realtek case that was filed in November 2022.  In addition, in February 2023, the case against LGE was stayed pending final resolution of the cases against Realtek and MediaTek and the outstanding IPR actions to which LGE is a party.   TCL, et. al. v. ParkerVision (PTAB) In May 2021, TCL, along with Hisense, filed petitions for IPR against U.S. patent 7,292,835 (“the ‘835 Patent”) and the ‘444 Patent, both of which are asserted in the infringement cases against these parties in the Western District of Texas.  In November 2021, the PTAB issued its decision to implement IPR proceedings for these two patents.  In December 2021, LGE filed nearly identical petitions against the same two patents along with a joinder motion requesting to join the existing petitions filed by TCL and Hisense.  In April 2022, the PTAB granted LGE’s joinder motion.  Oral hearings for these IPRs were held in September 2022.  As part of a patent license and settlement agreement entered into with Hisense in November 2022, Hisense withdrew its participation in these IPR proceedings.  In November 2022, the PTAB issued its written decision ruling that the challenged claims for both patents were unpatentable.  We have appealed these decisions.     13. Stock Authorization and Issuance   Stock Issuances – Equity Based Financings   Private Placements with Accredited Investors In January 2023, we entered into securities purchase agreements with accredited investors for the sale of an aggregate of 843,750 shares of our common stock at a price of $ 0.16 per share for aggregate proceeds of $ 0.14 million, including 62,500 shares to Sanford Litvack, a member of our Board of Directors.  The shares were registered for resale on a registration statement that was declared effective on May 11, 2023 ( File No. 333 - 271351 ).   17 Table of Contents   Common Stock Warrants   As of March 31, 2023 , we had outstanding warrants for the purchase of up to 10.3 million shares of our common stock.  The estimated grant date fair value of these warrants of $ 3.2 million is included in additional paid-in capital in our condensed consolidated balance sheets. As of March 31, 2023 , our outstanding warrants have an average exercise price of $ 0.75 per share and a weighted average remaining life of approximately 1.9 years.      14. Share-Based Compensation   There has been no material change in the assumptions used to compute the fair value of our equity awards, nor in the method used to account for share-based compensation from those stated in our 2022 Annual Report.   For the three months ended March 31, 2023 and 2022 , we recognized share-based compensation expense of approximately $ 0.2 million and $ 0.75 million, respectively.  Share-based compensation is included in selling, general and administrative expenses in the accompanying condensed consolidated statements of comprehensive income.  As of March 31, 2023 , there was $ 0.4 million of total unrecognized compensation cost related to all non-vested share-based compensation awards.  The cost is expected to be recognized over a weighted-average remaining life of approximately 0.9 years.     15. Income Taxes   The Company's effective income tax rate was 0.0 % for each of the three months ended March 31, 2023 and 2022 .  The 0.0 % effective rate for 2023 is due to NOL carryforwards not previously recognized as a tax benefit that we expect to be able to utilize in the current year to offset income tax expense related to current period income.     16. Related Party Transactions   On January 13, 2023, we sold 62,500 shares of our common stock to Sanford Litvack, one of our directors since October 2022, at $ 0.16 per share in a private placement transaction (see Note 13 ).        17. Subsequent Events   On May 4, 2023, we entered into a confidential letter agreement with Brickell whereby Brickell provided $ 5.0 million in new funding to us on substantially similar repayment terms as those set forth in our existing contingent payment agreement with Brickell, but at a lower interest rate.  We will use the proceeds for working capital purposes.     18 Table of Contents     ITEM 2.

Refer to Note 12 to our consolidated financial statements included elsewhere in this prospectus for a complete discussion of our patent enforcement proceedings.   Brickell Agreement We repaid Brickell $13.9 million in May 2023 from our patent licensing and settlement proceeds.  On May 4, 2023, we entered into a confidential letter agreement with Brickell whereby Brickell provided $5.0 million in new funding to us on substantially similar repayment terms as those set forth in our existing contingent payment agreement, but at a lower interest rate.  The new funding will be used for operations.     Other Debt and Equity Financings In January 2023, we received proceeds of approximately $0.7 million from the sale of five-year convertible notes to accredited investors.  The notes are convertible, at the holders' option, into shares of our common stock at a fixed conversion price of $0.16 per shares and bear interest at a stated rate of 9% per annum.  Interest is payable quarterly, and we may elect, subject to certain equity conditions, to pay interest in cash, shares of our common stock, or a combination thereof.  In addition, in January 2023, we received aggregate proceeds of approximately $0.14 million from the sale of common stock to accredited investors, including 62,500 shares to Sanford Litvack, a member of our Board of Directors, at a price of $0.16 per share.  The shares were registered for resale on a registration statement that was declared effective on May 11, 2023 (File No. 333-271351).   Liquidity and Capital Resources   We generated cash and restricted cash from operations of approximately $13.2 million for the three months ended March 31, 2023 and used cash for operations of $0.9 million for the three months ended March 31, 2022.  The increase in cash generated from operations from 2022 to 2023 is primarily due to proceeds received from the patent license and settlement agreement entered into in February 2023, net of contingent legal fees and expenses paid.  At March 31, 2023, we had cash and cash equivalents of approximately $0.1 million and restricted cash of approximately $13.9 million.  The restricted cash was used to make a $13.9 million repayment of principal on our secured contingent payment obligation in May 2023.       For the three months ended March 31, 2023, we received aggregate net proceeds from the sale of debt and equity securities, including the exercise of outstanding options and warrants, of approximately $0.8 million compared to approximately $0.1 million in proceeds received for the three months ended March 31, 2022.  We repaid approximately $0.04 million and $0.02 in debt obligations during the three months ended March 31, 2023 and 2022, respectively.  In May 2023, we repaid $13.9 million on our secured contingent payment obligation and received $5.0 million in new funding under that agreement (see Note 17).    We believe our current capital resources are sufficient to meet our liquidity needs for at least the next twelve months and we will not be required to seek additional capital.     20 Table of Contents   We expect to continue to invest in the support of our patent licensing and enforcement program. A significant amount of future proceeds that we may receive from our patent licensing and enforcement program will be first utilized to repay borrowings and legal fees and expenses under our contingent funding arrangements.  The long-term continuation of our business plan is dependent upon the generation of sufficient cash flows from our technologies and/or products 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 will have a material adverse effect on our ability to meet our long-term liquidity needs and achieve our intended long-term business objectives.   Financial Condition   Our working capital increased approximately $13.3 million from December 31, 2022 to March 31, 2023.  This increase in working capital is primarily the result of our restricted cash balance of $13.9 million, which is partially offset by an increase in current liabilities from the reclassification of an additional $0.8 million of convertible notes due in February and March 2024 from long-term to current liabilities.   Our long-term liabilities decreased $0.6 million from December 31, 2022 to March 31, 2023, primarily due to a $0.3 million decrease in the fair value of our contingent payment obligations, the reclassification of an additional $0.8 million of convertible notes due in February and March 2024 from long-term to current liabilities, and the conversion of $0.2 million in convertible notes by the holder, offset by the issuance of $0.7 million of new five-year convertible notes.   Results of Operations for the three months ended March 31, 2023 and 2022   Revenue and Cost of Sales We reported no licensing revenue for the three months ended March 31, 2022.  Licensing revenue was $25.0 million for the three months ended March 31, 2023, resulting from a patent license and settlement agreement entered into in February 2023.  The parties' performance obligations were met in February 2023 and we recognized revenue at that time.  Cost of sales for the three months ended March 31, 2023 and 2022 consists of amortization expense related to the patents covered under license agreements.  Although we anticipate additional revenue to result in 2023 and beyond from our patent enforcement actions, the amount and timing is highly unpredictable and there can be no assurance that we will achieve our anticipated results.   Selling, General, and Administrative Expenses Selling, general and administrative expenses consist primarily of litigation fees and expenses, personnel and related costs, including share-based compensation, for executive, Board, finance and accounting and technical support personnel for our patent enforcement program, and costs incurred for insurance and outside professional fees for accounting, legal and business consulting services.   21 Table of Contents   Our selling, general and administrative expenses increased by approximately $10.2 million, or 525.2%, during the three months ended March 31, 2023 when compared to the same period in 2022.  This is primarily the result of an $10.7 million increase in litigation fees and expenses and is partially offset by a $0.6 million decrease in share-based compensation.   The increase in litigation fees and expenses is the result of contingent legal fees and expenses recognized in 2023 in conjunction with the confidential patent license and settlement agreement reached in February 2023.   The decrease in our share-based compensation for the three-month period ended March 31, 2023 is the result of share-based compensation expense attributed to restricted stock units and nonqualified stock options awarded to executives, key employees and nonemployee directors in 2020 and 2021 being fully recognized as of December 31, 2022.  As of March 31, 2023, we had $0.4 million of total unrecognized compensation cost related to all non-vested share-based compensation awards that is expected to be recognized over a period of approximately 0.9 years.   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 significant 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 due to increases in funded amounts, passage of time, and changes in the probabilities based on the status of the funded actions.   For the three months ended March 31, 2023 and 2022, we recorded an aggregate decrease in the fair value of our secured and unsecured contingent payment obligations of approximately $0.3 million and $2.3 million, respectively.  The change in fair value for the three months ended March 31, 2023 was 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.   Off-Balance Sheet Transactions, Arrangements and Other Relationships   As of March 31, 2023, we had outstanding warrants to purchase approximately 10.3 million shares of our common stock. The estimated grant date fair value of these warrants of approximately $3.2 million is included in shareholders’ deficit in our condensed consolidated balance sheets. The outstanding warrants have a weighted average exercise price of $0.75 per share and a weighted average remaining life of approximately 1.9 years.   22 Table of Contents   Critical Accounting Policies   There have been no changes in accounting policies from those stated in our 2022 Annual Report.  We do not expect any newly effective accounting standards to have a material impact on our financial position, results of operations or cash flows when they become effective.   ITEM 3.
