**Technology Research and Development**

***InterDigital R&I***&nbsp;&nbsp;&nbsp;&nbsp;

InterDigital operates a diversified research and development operation, InterDigital Research & Innovation ("InterDigital R&I").

As an early and ongoing participant in the digital wireless market, InterDigital has developed pioneering solutions for cellular and Wi-Fi technologies that enable wireless transmission of voice, data and multimedia content in use today. That early involvement and our continued development of advanced digital wireless technologies have enabled us to create our significant worldwide portfolio of patents. InterDigital is also a leader in key video technologies, including 2D video coding and emerging technologies such as immersive video and AI-based video coding. Our current research efforts are focused on a variety of areas related to future technology and devices, including cellular wireless and Wi-Fi technologies, advanced video coding and transmission, and AI. The InterDigital R&I team's technical expertise is recognized by the worldwide wireless and video standards bodies where our delegates hold key leadership positions.

Our capabilities in the development of advanced technologies are based on the efforts of a highly specialized engineering team, leveraging leading-edge equipment and software platforms. In 2025 and 2024, our research and portfolio development costs were $211.4 million and $196.9 million, respectively, and the largest portion of this expense has been personnel costs.

*Wireless Technology*

We have a long history of developing cellular technologies that include physical layer design covering CDMA, TDMA, OFDM/OFDMA, and MIMO, radio interface protocols, as well as system architecture and services supporting cellular networks. Many of our inventions are being used in all 2G, 3G, 4G, and 5G wireless networks and mobile terminal devices. We continue to be engaged in development efforts to build and enhance our 3rd Generation Partnership Project ("3GPP") technology portfolio in the current and future generations including 5G Advanced and 6G. We are one of a handful of companies bringing wireless, video and AI technologies together to meet IMT 2030 requirements for 6G. The horizontal technologies we develop are essential to support a variety of use cases across several vertical market segments that use connected devices such as mobile phones, automobiles and autonomous vehicles, wearables, smart factories and smart homes, robots, drones and many other connected consumer electronic products including tablets and PCs. We are developing evolutionary and revolutionary solutions that enable connectivity in both licensed and unlicensed spectrum, terrestrial and non-terrestrial networks to provide ubiquitous coverage, across a large range of frequencies up to the terahertz (THz) bands.

<u>[**Table of Contents**](#ibb62662d68ca424983f0f56e1e5271de_7)</u>

Segments outside of 3GPP primarily fall within the scope of the IEEE 802.11 for Wi-Fi devices and IETF standards for Internet protocols. Our IEEE 802.11 standards-based inventions are used in devices that are certified for Wi-Fi 4/5/6/7 and provide improvements in spectral efficiency, higher throughput, reduced latency, energy efficiency, and many other features. We are developing new technologies towards Wi-Fi 8 by continuing novel innovations and participation in IEEE 802.11 standards and Wi-Fi Alliance forums.

*Advanced Video Coding and Transmission Technology*

An important and growing segment of wireless traffic is devoted to video streaming. We have a rich history in developing advanced technologies that address the challenges of video products and services. Specifically, in the area of video research, we have a long history of research and innovation in technologies that provide the basis for nearly all of the modern video codecs. We have been actively engaged in video codec standards development work in the ISO/IEC Moving Picture Expert Group (MPEG), the ITU-T Video Coding Expert Group (VCEG), the Joint Collaborative Team on Video Coding (JCT-VC) and the Joint Video Expert Team (JVET). Those efforts have focused on H.264/Advanced Video Coding, H.265/High Efficiency Video Coding ("HEVC") versions 1 to 4, as well as development of the H.266/VVC and the MPEG Immersive (MPEG-I) standards suite. InterDigital R&I is now conducting research in groundbreaking technologies preparing for the next generation of video codecs beyond VVC using both traditional and AI-based techniques. The recent acquisition of the Deep Render team has enhanced our ability to develop novel end-to-end AI-based codecs. Even codecs, such as AV1/VP9, developed by non-standard groups, use fundamental techniques we have been instrumental in developing. In addition to the video codec, we have pioneered technologies that enhance video quality in other ways. An example is the technology enabling production, distribution and display of high dynamic range (HDR) video that leverages AI to maximize the quality of video delivered to consumers. We are also investigating new media coding such as point cloud compression, haptics, or avatars using both traditional and AI-based techniques that will form the basis of future immersive video experiences. The technologies we have developed in video compression and in high quality media delivery form the foundation of streaming and many other cloud services and enable consumers to enjoy them on their favorite devices.

*Artificial Intelligence/Machine Learning (AI/ML)*

InterDigital is using AI to drive both wireless and video standards towards the future, leveraging AI as a valuable tool to drive efficiency and new capabilities in wireless networks and in video compression and delivery systems. We are researching a variety of aspects of AI that can be applied to complex problems in video and wireless technologies. Those areas of research include: energy-efficient deep learning aimed at reducing the energy-intensive rollout of AI; design of novel video codecs based on deep learning techniques and optimized for different use cases (e.g., for machine consumption); and the integration of AI into current and next generation 3GPP wireless systems. InterDigital is also actively investing in leveraging AI as technology, using existing large language model (LLM) based solutions to help us improve our research outcomes, streamline our internal workflows, and to further enhance our IP portfolio.

Companies participating in these markets make, import, use or sell services making use of a number of video codecs and other technologies covered by our patent portfolio. In 2025, we initiated patent infringement actions involving major streaming ecosystem participants, including Disney and Amazon, relating to certain video technologies. During 2025, in our matter with Disney, we were awarded injunctions against Disney video streaming services by courts in Brazil and Germany. These matters are more fully discussed in Note 12, "Litigation and Legal Proceedings," to the Notes to Consolidated Financial Statements included below in Part II, Item 8 of this Form 10-K.

***Overview of Patent Licenses***

The majority of our revenue is generated from fixed-fee patent license agreements, with a smaller portion coming from variable royalty agreements. Our revenue could also come from hybrid agreements, which have both a fixed-fee and variable component if certain unit caps are exceeded. Upon entering into a new patent license agreement, consideration should be paid for sales made prior to the period in which the agreement was executed, to the extent those past sales were previously unlicensed (i.e., catch-up revenue), in addition to royalties or license fees on licensed products and services sold during the term of the agreement. We expect that, for the most part, new license agreements will follow this model. Almost all of our patent license agreements provide for the payment of royalties based on sales of licensed products and services (convenience-based licenses), as opposed to the payment of royalties if the manufacture, sale or use of the licensed product infringes one of our patents (infringement-based licenses).

Our variable and hybrid royalty license agreements typically contain provisions that give us the right to audit our licensees' books and records to ensure compliance with the licensees' reporting and payment obligations under those agreements. From time to time, these audits reveal underreporting or underpayments under the applicable agreements. In such cases, we seek payment for the amount owed and enter into negotiations with the licensee to resolve the discrepancy.

For a discussion of our revenue recognition policies with respect to patent license agreements, see "Item 7. *Management's Discussion and Analysis of Financial Condition and Results of Operations - Overview - Critical Accounting Policies and Estimates - Revenue Recognition - Patent License Agreements*."

*Licensing Through Platforms* 

We are part of a joint licensing program with Sony relating to digital televisions ("DTVs") and standalone computer display monitors ("CDMs") (such program, the "Madison Arrangement"), and act as exclusive licensing agent. Under the Madison Arrangement, InterDigital and Sony combine portions of their respective DTV and CDM patent portfolios and have created a combined licensing opportunity for DTV and CDM manufacturers. As licensing agent for the Madison Arrangement, we are responsible for making decisions regarding the prosecution and maintenance of the combined patent portfolio and the licensing and enforcement of the combined patent portfolio in the field of use of DTVs and CDMs. Refer to Note 10, "*Obligations*," within the Notes to the Consolidated Financial Statements included in Part II, Item 8 of this Form 10-K for further information about the Madison Arrangement.

In 2016, InterDigital joined Avanci, the industry's first marketplace for the licensing of cellular standards-essential technology for the IoT. The licensing platform brings together many of InterDigital's peers in standards-essential technology leadership, and makes 2G, 3G, 4G, and 5G standards-essential patents available to IoT players in specific product segments with one flat-rate license. The Avanci licensing programs in specific product segments for the IoT industry will provide access to the entire applicable standards-essential cellular patent portfolios held by all of the platform participants, as well as any additions to their portfolios during the term of the license. Since December 2017, Avanci has primarily focused on the automotive market, and has signed patent license agreements with BMW Group, Audi, Ford, Toyota, BYD, and Volvo Cars, among others, collectively representing over 80% of annual connected car shipments. Through Avanci, InterDigital's cellular standard essential patents are also made available to certain other product verticals in the IoT area, such as smart meters and vehicle aftermarket products.

**Overview of Smartphone, Consumer Electronics, IoT, and Video Services Industries** 

The primary markets for our wireless and video technologies are the smartphone, consumer electronics, IoT/Automotive, and video services markets. The smartphone market, with an estimated 1.2 billion units shipped worldwide in 2025, is driven by several large, global brands. We now have eight of the ten largest smartphone vendors based on shipments and approximately 85% of the entire global smartphone market under license. The smartphone market once again grew in 2025 after several stagnant years due to the continued global uptake of 5G smartphones as well as the migration from feature phones to smartphones in emerging regions. Continued growth beyond 2025 is anticipated due in part to the introduction of new technologies and form factors.

<u>[**Table of Contents**](#ibb62662d68ca424983f0f56e1e5271de_7)</u>

In addition to smartphones, there is a large universe of other consumer electronic devices and ecosystems, with a mix of mature and emerging, as well as consolidated and fragmented, device segments. After smartphones, televisions represent one of the largest markets with more than 200 million units shipped globally. Other key consumer electronics device categories include tablets and personal computers, set-top-boxes and streaming media players, gaming consoles, wearables and smart home products. As of December 31, 2025, we have approximately 60% of the tablets and personal computers market and 35% of the television market under license and we are pursuing licenses with the remaining market to drive revenue growth in this area.

IoT/Automotive is an important and relatively new market that is expected to result in a significant increase in the number of connected devices worldwide and unlock new business capabilities. Total global cellular IoT device shipments are expected to grow from approximately 550 million in 2025 to approximately 800 million by 2029. Automobiles represent a significant opportunity within the IoT market, with approximately 65 million connected passenger vehicles shipped in 2025, which is expected to grow significantly in the future.

Video Services, a rapidly growing market, encompass a wide range of consumer video entertainment platforms, including SVOD, AVOD, Virtual Multichannel Video Programming Distributor ("vMVPD"), Free Ad-Supported Streaming TV ("FAST"), and social media platforms. Collectively, the Video Services market is expected to grow from approximately $475 billion of annual revenue in 2025 to approximately $675 billion of annual revenue by 2029.

**Overview of Standardization**

To achieve economies of scale and support interoperability among different participants, many wireless and consumer electronics products have been designed to operate in accordance with certain industry standards and common technical specifications. Wireless industry standards, for example, are formal requirements and guidelines for engineers, designers, manufacturers and service providers that regulate and define the use of the radio frequency spectrum in conjunction with providing detailed specifications for wireless communications products. The consumer electronics industry also implements many of the same standards, including standards related to Wi-Fi and increasingly, cellular technologies, as well as a broad range of video coding standards and technical specifications that enable the efficient rendering of video content. Technology related to these video coding standards also enable the media content and video streaming industries. New standards and specifications are typically adopted with each new generation of products and services, are often compatible with previous generations and are defined to ensure equipment interoperability and regulatory compliance.

SDOs, which facilitate and govern the development of standards, typically ask participating companies to declare formally whether they believe they hold patents or patent applications essential or potentially essential to a particular standard and whether they are willing to license those patents on either a royalty-bearing basis on fair, reasonable and nondiscriminatory terms or on a royalty-free basis. To manufacture, have made, sell, offer to sell or use such products on a non-infringing basis, a manufacturer or other entity doing so needs to obtain a license from the holder of essential patent rights. The SDOs neither have enforcement authority against entities that fail to obtain required licenses, nor do they have the ability to protect the intellectual property rights of holders of essential patents.

InterDigital often publicly characterizes aspects of its business, including license agreements and development projects, as pertaining to industry standardized technologies such as, for example, 3G, 4G, 5G, Wi-Fi, HEVC, and VVC. In doing this, we generally rely on the positions of the applicable SDOs in defining the relevant standards. However, the definitions may evolve or change over time, including after we have characterized certain transactions.

**Business Activities**

***2025 Patent Licensing Activity***

During 2025, we entered into eight patent license agreements as discussed below.

*<u>Direct Licenses</u>*

In 2025, we signed new multi-year, worldwide, non-exclusive, royalty-bearing license agreements with two major Chinese smartphone vendors, vivo and Honor. As a result, we now have eight of the ten largest smartphone vendors based on shipments and approximately 85% of the entire global smartphone market under license.

In April 2025, we signed a new multi-year license agreement with HP Inc. The agreement licenses HP personal computers to InterDigital's Wi-Fi and video decoding technologies.

Additionally, we entered into device licenses covering our technologies with a significant social media company, along with Eaton, Seiko Solutions Inc., Sharp, and Teltronic.

<u>[**Table of Contents**](#ibb62662d68ca424983f0f56e1e5271de_7)</u>

*<u>Samsung Arbitration</u>*

In 2022, we agreed to renew our patent license agreement with Samsung and enter into binding arbitration to determine the final terms of the license. In 2023, we began recognizing revenue for Samsung at a conservative level consistent with the revenue we recognized from our patent license agreement that expired on December 31, 2022.

On July 28, 2025, a panel of International Chamber of Commerce arbitrators determined the royalties of the patent license agreement covering Samsung's products, other than digital televisions and computer display monitors which have been licensed under a separate agreement. The arbitration panel set the total royalties at $1.05 billion for the eight-year patent license, which commenced on January 1, 2023 and runs through December 31, 2030. Under this agreement, we now recognize approximately $131 million of recurring revenue per year, a 67% increase from the previous license agreement. In 2025, the agreement contributed $118 million of catch-up revenue due to a true-up of the $78 million per year we had been recognizing based on the level of our prior agreement from January 1, 2023 to June 30, 2025.

***Customers Generating Revenue Exceeding 10% of Total 2025 Revenue***

A small number of customers historically have accounted for a significant portion of our consolidated revenue. In fiscal 2025, revenue (in descending order) from Samsung, Apple, and vivo each comprised 10% or more of our consolidated revenue. Additional information regarding revenue concentrations is provided in this Annual Report in Note 4, "*Segment and Concentration Information*" in the Notes to Consolidated Financial Statements included in Part II, Item 8, of this Form 10-K.

As discussed above in *2025 Patent Licensing Activity*, the arbitration panel of International Chamber of Commerce set the total royalties for our Samsung patent license at $1.05 billion for the eight-year patent license, which commenced on January 1, 2023 and runs through December 31, 2030. This agreement covers Samsung's products other than digital televisions and computer display monitors.

We also recognized revenue from the patent license agreement signed in 2024 with Samsung (the "Samsung TV agreement"). The Samsung TV agreement licenses Samsung's digital TVs and computer display monitors under InterDigital's joint licensing program with Sony and includes licenses to key technologies including ATSC 3.0, as well as licenses under InterDigital's patents including HEVC, VVC and Wi-Fi. This agreement expired as of December 31, 2025. We are actively working to renew this agreement on terms consistent with the licensees' respective market positions and utilization of our technology.

In 2022, we renewed a multi-year, royalty-bearing, worldwide, and non-exclusive patent license agreement with Apple (the "Apple PLA"). The agreement sets forth terms covering Apple's business, including its sale of 3G, 4G, and 5G cellular and wireless-enabled products. The term of the Apple PLA extends through September 30, 2029.

In 2025, we signed a new multi-year, worldwide, non-exclusive, royalty-bearing license agreement with vivo, a major Chinese smartphone vendor. The term of the vivo patent license agreement runs through June 30, 2028.

***Patent Infringement and Declaratory Judgment Proceedings***

From time to time, if we believe a party is required to license our patents in order to manufacture, use and/or sell certain products and such party refuses to do so, we may in certain circumstances, institute legal action against them. Enforcing our intellectual property through legal action is an important alternative to bilateral negotiations with respect to licensees who engage in the pernicious practice of "holdout". In recent years, courts in various jurisdictions have addressed "holdout" behavior, recognizing that fair, reasonable and non-discriminatory ("FRAND") obligations are bilateral and failure of implementers to act in a FRAND manner can result in certain penalties. We welcome this development as it incentivizes potential licensees to negotiate in a timely and reasonable fashion as well as providing a necessary balance to FRAND negotiations. If a party is willing to take a license but we cannot agree with the party on a fair price, we may, in certain circumstances agree with such party to have royalties or other terms set by third party adjudicators (such as arbitrators).

------

<u>[**Table of Contents**](#ibb62662d68ca424983f0f56e1e5271de_7)</u>

Enforcement of our patent portfolio has typically taken the form of a patent infringement lawsuit or an administrative proceeding, such as a Section 337 proceeding before the U.S. International Trade Commission ("USITC" or the "Commission"). In a patent infringement lawsuit, we would typically seek damages for past infringement, an injunction against future infringement, declaratory judgment and/or other relief. In a USITC proceeding, we would seek an exclusion order to bar infringing goods from entry into the United States, as well as a cease and desist order to bar further sales of infringing goods that have already been imported into the United States. Parties may bring administrative and/or judicial challenges to the validity, enforceability, essentiality and/or applicability of our patents to their products or seek to petition a court to establish a rate and/or terms for a license to our patents. Parties may also allege that our efforts to enter into a license with that party do not comply with any obligations we may have in connection with our participation in standards-setting organizations, and therefore that we are not entitled to the relief that we seek. For example, a party may allege that we have not complied with an obligation to offer (or be prepared to offer) a license to that party for patents that are or may become standards-essential patents ("SEPs") on FRAND terms and conditions, and may also file antitrust claims or regulatory complaints on that or other bases, and may seek damages or other relief based on such claims. In addition, a party might file a declaratory judgment action to seek a court's declaration that our patents are invalid, unenforceable, not infringed by the other party's products or are not SEPs, or that certain of our patents are subject to FRAND obligations. Our response to such a declaratory judgment action may include claims of infringement. When we include claims of infringement in a patent infringement lawsuit, a favorable ruling for the Company can result in the payment of monetary damages for past manufacture, use and/or sale of the patented invention, the setting of terms and conditions for a license, issuance by the court of an injunction enjoining the infringer from manufacturing, using and/or selling infringing products and/or a declaration of FRAND compliance.

***Contractual Arbitration Proceedings***

We and our licensees, in the normal course of business, may have disagreements as to the rights and obligations of the parties under applicable agreements. For example, we could have a disagreement with a licensee as to the amount of reported sales and royalties. Our patent license agreements typically provide private confidential arbitration as the mechanism for resolving disputes with our licensees. In arbitration, licensees may seek to assert various claims, defenses, or counterclaims, such as claims based on waiver, promissory estoppel, breach of contract, fraudulent inducement to contract, antitrust, and unfair competition. Arbitration proceedings can be resolved through an award rendered by the arbitrators or by settlement between the parties. Parties to arbitration might have the right to have the award reviewed in a court of competent jurisdiction; however, based on public policy favoring the use of arbitration, it is generally difficult to have arbitration awards vacated or modified. The party securing an arbitration award may seek to have that award confirmed as a judgment through an enforcement proceeding. The purpose of such a proceeding is to secure a judgment that can be used for, if need be, seizing assets of the other party.

In addition, arbitration may be a particularly effective means for resolving disputes with prospective licensees concerning the appropriate FRAND terms and conditions for license agreements that include SEPs, particularly where negotiations have otherwise reached an impasse. Binding arbitration to resolve the terms and conditions of a worldwide FRAND license to our patent portfolio is an efficient and cost-effective mechanism, as it allows the parties to avoid piecemeal litigation in multiple jurisdictions and ensures that an enforceable patent license agreement that is consistent with FRAND commitments will be in place at the end of the arbitration process.

***Competition***

With respect to our technology development activities and resulting commercialization efforts, we face competition from companies, including other wireless and video technology companies, consumer electronics device companies, semiconductor companies, wireless operators, video streaming and cloud service companies, and other technology providers, developing other and similar technologies that are competitive with our technologies that we may market or set forth into the standards-setting arena.

Due to the exclusionary nature of patent rights, we do not compete, in a traditional sense, with other patent holders for patent licensing relationships or sale transactions. Other patent holders do not have the same rights to the inventions and technologies encompassed by our patent portfolio. In any device, piece of equipment, or service that contains intellectual property, the manufacturer or implementer may need to obtain licenses from multiple holders of intellectual property. In licensing our patent portfolio, we compete with other patent holders for a share of the royalties that certain licensees may argue to be the total royalty that is supported by certain products or services, which they may argue face practical limitations. We believe that licenses under a number of our patents are required to manufacture and sell wireless products, as well as other consumer electronics devices, and to implement certain technology services. However, numerous companies also claim that they hold patents that are or may be essential or may become essential to standards-based technology deployed on wireless products, other consumer electronics devices and services. To the extent that multiple parties all seek royalties on the same product or service, the manufacturers could claim to have difficulty in meeting the financial requirements of each patent holder. In the past, certain manufacturers have sought antitrust exemptions to act collectively on a voluntary basis. In addition, certain manufacturers have sought to limit aggregate licensing fees or rates for SEPs.

***Sustainability***

We believe our innovation provides the framework for a future increasingly shaped by the profound convergence of wireless, video, and AI technologies. As these technologies become more ubiquitous and deliver immense benefits across the global ecosystem, we believe it is important that the future we are enabling continues to be anchored by a core set of values, ethics, and principles. Our heritage of innovation has produced technologies that fundamentally improve efficiency and power consumption across billions of devices, network infrastructure, and delivered services. Our sustainability principles continue this legacy and shape our pursuit of a more sustainable, representative, diverse, and equitable world.

Our Nominating and Corporate Governance Committee has primary oversight over environmental, social and other sustainability matters, which it exercises in conjunction with the committees of the Board. In addition, our Chief Financial Officer oversees a committee of senior executives that steers the process of setting strategies, policies and goals related to economic, environmental and social topics. We are committed to sustainable business principles, to thinking long-term, and to making strategic decisions that adhere to our mission and values. We strive to focus and make progress on initiatives that matter most to our business, our employees, communities, and external stakeholders.

We are committed to driving positive progress towards reducing the environmental footprint that the deployment of 5G, wireless networks, and other video technologies will bring. While our business activities do not entail the same concerns related to manufacturing or raw materials sourcing and disposal, our corporate sustainability strategy addresses the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• investing in best practices to track and reduce our carbon footprint, including environmental considerations, and reporting related to data center needs;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• investigating and reducing unnecessary energy consumption; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• continuing to manage our environmental footprint with our office improvements

As a pure research business, we consider our carbon impact through our "handprint" and the ways our innovation and contributions to global standards empower energy efficiencies and sustainable outcomes. Our research not only offers significant advances in the operational performance of various systems, but also reduced environmental impact through efficiency improvements, reduced power consumption, and by altering the way that products are used, serviced, or maintained worldwide.

InterDigital ranks among the industry leaders for highest patent quality for 5G and video codec patents. 5G and video codec technology is designed to efficiently use energy throughout its ecosystem and will play a significant role in promoting and attaining sustainability goals. We published white papers exploring the state of video and media sustainability, highlighting the strategies that leading enterprises are leveraging to meet short- and long-term sustainability objectives. The video industry accounts for over 80% of all internet data, and InterDigital's sustainable video innovation tackles the energy intensive nature of video streaming and display technologies. Roughly 67% of video-related energy consumption is attributed to TV devices, and InterDigital's award-winning Pixel Value Reduction (PVR) solution optimizes the brightness of pixels on a device display to reduce energy consumption without compromising the perceived video quality. By applying AI expertise to InterDigital's Deep PVR, our solution can achieve an up to 15% reduction in a display's power consumption. The resulting energy savings per device becomes exponentially significant if applied across billions of displays worldwide.

The foregoing discussion includes information regarding sustainability matters that we believe may be of interest to our shareholders generally. We recognize that certain other stakeholders (such as customers, employees and non-governmental organizations), as well as certain of our shareholders, may be interested in more detailed information on these topics. We encourage you to review our most recent Corporate Sustainability Report (located on our website) for more detailed information regarding our Corporate Sustainability governance, goals, priorities, accomplishments and initiatives, as well as the Corporate Governance section of our most recent Proxy Statement, and our Corporate Governance Principles and Practices (located on our website), for additional information regarding governance matters, including Board and Committee leadership, oversight, roles and responsibilities, and Director independence, tenure, refreshment and diversity.

***Human Capital***

We are committed to making InterDigital an exceptional place to work, fostering a workplace where all employees feel valued, respected, included, and challenged. We aim to create an environment that attracts, engages, and retains a talented workforce that drives the company's growth and long-term sustained success. Our Human Capital Committee is responsible for overseeing our policies and strategies related to culture and human capital.

As of December 31, 2025, our global workforce included approximately 460 employees, with approximately 240 employees based outside the United States; nearly all were full-time. Our employees in France are represented by works councils and are subject to collective bargaining agreements. None of our employees based in the United States or Canada are unionized or subject to collective bargaining agreements. Management believes that its relationships with our employees and works councils are strong and productive.

------

To attract and retain the specialized talent required to compete in our markets, we focus on the following human capital priorities:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Health, Safety & Well-Being.** We support employee well-being through a flexible work model, holistic benefits, and wellness-oriented policies. We provide a minimum of twelve weeks of paid parental leave globally and offer paid time off for employee volunteerism through our "Charity Day" program.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Compensation & Benefits.** Our compensation programs are designed to be market competitive and to reward individual contributions aligned with our strategy. Total rewards plans generally include base salary, short- and long-term incentives, healthcare benefits, retirement savings plans, well-being programs, and hybrid work arrangements, and both monetary and social recognition across our global locations. We routinely review our programs to support talent attraction and retention.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Talent and Culture.** Our Talent philosophy focuses on cultivating a culture of high performance, career development, and employee engagement, empowering our workforce to reach its full potential. We invest in employee development and engagement through our talent practices, leadership development resources, and performance management processes. In 2025, we refreshed our company values based on employee feedback to align with our evolving culture. We continue to enhance our talent assessment processes, including performance reviews, succession planning for key and senior roles, and employee feedback mechanisms. We believe our culture and competitive total rewards support strong employee retention.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Inclusive Global Workforce.** Our work in advancing wireless, video, and AI technologies requires a highly educated, skilled, and specialized workforce, and we believe an inclusive environment supports collaboration and innovation. We are a company of world-class inventors, representing more than 60 countries, that strive to foster a diverse and stimulating environment where creative, intelligent, and ambitious people can develop and grow.

The foregoing discussion is intended to address human capital matters of interest to shareholders generally. Stakeholders seeking additional detail are encouraged to review the "Human Capital" section of our most recent Corporate Sustainability Report available on our website, which includes our most recent Consolidated EEO-1 reports.

**Risks Related to Our Business**

***Our plans to expand our revenue opportunities may not be successful.***

As part of our business strategy, we regularly seek to expand our revenue opportunities both organically and inorganically. In particular, we have expanded our licensing activities beyond device-based licensing revenue to certain video and cloud-based service providers. The market for licensing video and cloud-based services is not as developed as device-based licensing programs. As a result, video and cloud-based service providers do not have a significant volume of comparable agreements against which to compare our offers and may use this as a reason to delay our negotiations with such providers. Additionally, our pricing models may not reflect the value of our technologies in the eyes of our customers. Because we have not yet entered into our first video services license, the revenue we expect to realize from this program is uncertain and inherently subject to risk. And, because the services licensing market is less developed, holdout behavior may be more likely than in device licensing. Service providers may also opt to use alternative technologies for which we have little or no patent coverage. Accordingly, we may not be able to enter into license agreements with these providers on terms that are favorable to us, or at all. Services revenue is a key component of our future growth, and if we are unable to successfully execute a services licensing program and monetize our video patents in respect of video services as we currently intend, we will not reach our revenue and other financial targets, and our business, financial condition and prospects could be harmed.

***Challenges relating to our ability to enter into new license agreements and renew existing license agreements could cause our revenue and cash flow to decline.*** 

We face challenges in entering into new patent license agreements. Most implementers of our technology do not voluntarily seek to enter into license agreements with us before they commence manufacturing and/or selling devices that use our patented inventions. The process of identifying users of our inventions and negotiating license agreements with reluctant prospective licensees requires significant time, effort and expense. Some infringers may act in bad faith, by attempting to hold out on taking a license altogether or behaving opportunistically in license negotiations. Even good faith negotiations are often very long and complex, involving significant company time and resources. Given these challenges, we cannot ensure that we will be able to enter into patent license agreements either at all or on terms acceptable to us. Additionally, given the large number of implementers using our patented inventions, we may not be able to identify all potential licensees. Once identified, it is not feasible for us to seek licenses from all users of our patented technologies, so we have to make strategic decisions with respect to which companies we should approach for license negotiations. In particular, the CE/IoT market is much more fragmented than our traditional smartphone core. Uncertainty related to entry into new license agreements impacts our forecasts and ultimately, revenue, cash flow and business.

We also face challenges in renewing our existing license agreements. Although we endeavor to renew license agreements prior to their expiration, due to various factors, including the technology and business needs and competitive positions of our licensees and, at times, reluctance on the part of our licensees to participate in renewal discussions, we may not be able to renegotiate the license agreements on acceptable terms before the expiration of the license agreement, or at all. Delays in renegotiating and renewing a license agreement prior to its expiration, cause gaps in time during which we may be unable to recognize revenue from that licensee. We may also be forced to renegotiate and renew the license agreement on terms that are more favorable to such licensee. If we fail to renegotiate and renew our license agreements prior to their expiration, at all or on terms that are favorable to us, our forecasts, revenue and cash flow could be materially adversely affected.

***Royalties or other terms under our patent license agreements could be subject to determination through arbitration or other third-party adjudications or regulatory or court proceedings, and arbitrators, judges or other third-party adjudicators or regulators could make unfavorable determinations.*** 

Historically, we strive for the terms of our patent license agreements, including royalties, to be reached through arms-length bilateral negotiations with our licensees. We could agree, as we did with Samsung and Lenovo pursuant to binding arbitration agreements, to have royalties and any other disputed terms set by third party adjudicators (such as arbitrators). We have no guarantee that the royalties or other terms set by arbitrators, courts or other third parties will be favorable to us. It is possible that courts or regulators could decide to set or otherwise determine the FRAND consistency of such terms or the manner in which such terms are determined, including by determining a worldwide royalty for our portfolio. Changes to or clarifications of our obligations to be prepared to offer licenses to SEPs on FRAND terms and conditions could require such terms, including our royalties, to be determined through third party adjudications. Finally, we and certain of our current and prospective licensees have initiated, and we and others could in the future initiate, legal proceedings or regulatory proceedings requesting third party adjudicators or regulators to set FRAND terms and conditions for a worldwide license to our SEPs or our entire portfolio, or to determine the FRAND-consistency of current terms and conditions in our patent license agreements. Chinese courts have affirmed their position that in certain SEP licensing disputes, Chinese courts can set worldwide royalties, and in December 2023, one such court issued such a decision setting a worldwide royalty for Nokia's cellular patents. We have faced similar proceedings with OPPO in China to determine a worldwide royalty for certain of our SEPs as well as royalty-setting proceedings in the UK initiated by Amazon and Tesla. If any court or arbitration tribunal decision sets a worldwide royalty rate that is unfavorable to us, our standard essential patent portfolio could be significantly devalued as it relates to the FRAND royalty an implementer should pay, which could in turn negatively impact pricing with other licensees.

To the extent that our patent royalties for our patent license agreements are determined through arbitration or other third party adjudications or regulatory or court proceedings rather than through bilateral negotiations, because such proceedings are inherently unpredictable and uncertain and there are currently few precedents for such determinations, it is possible that royalties may be lower than our accounting estimates and/or comparable licenses. This could also have a negative impact on royalties we are able to obtain from future licensees, which may have an adverse effect on our revenue and cash flow and render us unable to meet our revenue and other financial targets. Prospective customers may delay, and in some cases have delayed, negotiations on the basis of an adverse decision. In addition, to the extent that other terms and conditions for our patent license agreements are determined through such means, such terms and conditions could be less favorable than our historical terms and conditions, which could have an adverse effect on our licensing business more broadly.

***We could continue to be involved in a number of costly litigation, arbitration and administrative proceedings to enforce or defend our intellectual property rights and to defend our licensing practices.*** 

Although we always seek to enter into licenses through bilateral negotiations, sometimes licensees are unwilling and litigation is necessary. This may be even more true with respect to video services licensing than device licensing, because the licensing market is less developed. While some companies seek licenses before they commence manufacturing and/or selling devices or services that use our patented inventions, the vast majority do not. Consequently, we approach companies and seek to establish license agreements for using our inventions. We expend significant time and effort identifying users and potential users of our inventions and negotiating license agreements with companies that may be reluctant to take licenses. If a third party implementer is unwilling to take a license on reasonable terms or in a reasonable time frame, or at all, we have in the past commenced, and may in the future commence, legal or administrative actions against such third parties to enforce our intellectual property rights. In turn, we have faced, and expect to continue to face, counterclaims and other legal proceedings that challenge the essential nature of our patents, or that claim that our patents are invalid, unenforceable or not infringed. Litigation adversaries have and may continue to allege that we have not complied with certain commitments to standards-setting organizations and therefore that we are not entitled to the relief that we seek. Parties have also filed, and may in the future file, antitrust claims, unfair competition claims or regulatory complaints on that or other bases, and may seek damages and other relief based on such claims. Litigation adversaries have also filed against us, and other third parties may in the future file, validity challenges such as inter partes proceedings in the USPTO or the China National Intellectual Property Administration, which can lead to delays of our patent infringement actions as well as potential findings of invalidity. Such parties may also seek to obtain a determination that our patents are not infringed, are not essential or are unenforceable.

Litigation may be also required to protect our trade secrets, enforce patent license and confidentiality agreements or determine the validity, enforceability and scope of proprietary rights of others. The cost of enforcing and defending our intellectual property and of defending our licensing practices has been and may continue to be significant, in particular with rising fees from outside counsel. As a result, we could be subject to significant legal fees and costs, including in certain jurisdictions the costs and fees of opposing counsel if we are unsuccessful. In addition, litigation, arbitration and administrative proceedings require significant key employee involvement for significant periods of time, which could divert these employees from other business activities.

***Potential patent and litigation reform legislation, potential USPTO and international patent rule changes, potential legislation affecting mechanisms for patent enforcement and available remedies, and potential changes to the intellectual property rights ("IPR") policies of worldwide standards bodies, as well as rulings in legal proceedings, may affect our investments in research and development and our strategies for patent prosecution, licensing and enforcement and could have a material adverse effect on our business.*** 

Potential changes to certain U.S. and international patent laws, rules and regulations may occur in the future, some or all of which may affect our research and development investments, patent prosecution or maintenance costs, the scope of future patent coverage we secure, the number of forums in which we can seek to enforce our patents, the remedies that we may be entitled to in patent litigation, and attorneys' fees or other remedies that could be sought against us, and may require us to reevaluate and modify our research and development activities and patent prosecution, licensing and enforcement strategies. For example, the State Administration for Market Regulation in China regularly reviews its policies related to intellectual property and antitrust laws, and any such review could result in ambiguous standards and/or create a worse position for patent holders like us. Additionally, there is uncertainty surrounding future EU IP policy. In 2023, the European Commission ("EC") introduced a proposal for SEP regulation that would have increased regulation of and requirements on SEP holders. Following discussion and debate inside of the European Parliament ("EP") and the EC, the EC withdrew the proposed policy in 2025, but discussions between the EP and EC continue as they relate to the future of SEPs and FRAND policy in the EU. Any change to the legal or regulatory landscape as a result of this review could impact our ability to negotiate license agreements on favorable terms or at all, while also limiting our potential legal remedies and materially impacting our business. Further, legislation designed to reduce the value of SEPs and alter the U.S. patent system, including legislation designed to reduce the jurisdiction and remedial authority of the USITC, has periodically been introduced in Congress.

Any potential changes in the law, the IPR policies of standards bodies or other developments that reduce the available forums or the types of relief available in such forums (such as injunctive relief), restrict permissible licensing practices (such as our ability to license on a worldwide portfolio basis) or that otherwise cause us to seek alternative forums (such as arbitration or state court), would make it more difficult for us to enforce our patents, whether in adversarial proceedings or in negotiations. Because we have historically depended on the availability of certain forms of legal process to enforce our patents and obtain fair and adequate compensation for our investments in research and development and the unauthorized use of our intellectual property, developments that undermine our ability to do so could have a negative impact on future licensing efforts.

Rulings in our legal proceedings, as well as those of third parties, may affect our strategies for patent prosecution, licensing and royalty setting and enforcement. For example, in the past, the USITC and U.S. courts, including the U.S. Supreme Court, have taken actions that have been viewed as unfavorable to patentees, including us. Decisions that occur in the U.S. or in international forums may change the law applicable to various patent law issues, such as, for example, patentability, validity, claim construction, patent exhaustion, patent misuse, permissible licensing practices, available forums, and remedies such as damages and injunctive relief, in ways that are detrimental to the ability of patentees to enforce patents and obtain suitable relief.

We continue to monitor and evaluate our strategies for prosecution, licensing and enforcement with regard to these developments; however, any resulting change in such strategies may have an adverse impact on our business and financial condition.

***Our business and operations may be adversely affected by a deterioration in United States-China relations or broader trade and geopolitical conditions.***

The imposition of tariffs by the United States could materially harm our business. Companies headquartered in China currently comprise a substantial portion of customers that utilize our patented inventions in their devices and services. Our ability to renew license agreements with current licensees in China as well as license new manufacturers is, among other things, affected by the macroeconomic and geopolitical climate, as well as our business relationships and perceived reputation in China. Although the U.S. and Chinese governments are regularly engaged in various trade discussions, the imposition of tariffs by the US government in 2025 increased trade tensions, both with China and globally.

Countermeasures imposed in response to such government actions could materially harm our business prospects, financial condition and cash flow. Currently, the future of existing tariffs, and the possibility for new tariffs or changes in trade policies, remains uncertain. So far, these tariffs and trade policies have not had a significant impact on our ability to develop foundational technologies or to participate and lead open standard development, or our business operations or financial results more generally; however, there is no guarantee that we can avoid the impact of tariff and related economic effects in the future, and these trade measures and any retaliatory measures imposed could directly or indirectly harm our business. Our ability to renew or conclude new license agreements could also be affected by economic uncertainty, particularly in the handset market, in China or globally.

------

<u>[**Table of Contents**](#ibb62662d68ca424983f0f56e1e5271de_7)</u>

China is a key market for us, and any of the above-mentioned factors could harm our ability to execute our business plans. The ultimate impact of ongoing trade tensions is uncertain, but if tensions continue or escalate, we could suffer material harm to our business, financial condition and operating results.

***We may face setbacks in defending our patent licensing practices.*** 

Adverse decisions in litigation or regulatory actions relating to our licensing practices, including, but not limited to, findings that we have not complied with our FRAND commitments and/or engaged in anticompetitive or unfair licensing activities or that any of our license agreements are void or unenforceable, could have an adverse impact on our cash flow and revenue. Regulatory bodies may assess fines in the event of adverse findings, and as part of court or arbitration proceedings, a judgment could require us to pay damages (including the possibility of treble damages for antitrust claims). In addition, to the extent that legal decisions find patent license agreements to be void or unenforceable in whole or in part, that could lead to a decrease in the revenue associated with and cash flow generated by such agreements, and, depending on the damages requested, could lead to the refund of certain payments already made. Such decisions could also cause serious reputational harm. Finally, adverse legal decisions related to our licensing practices could have an adverse effect on our ability to enter into license agreements, which, in turn, could cause our cash flow and revenue to decline.

***We face competition from companies developing other or similar technologies.*** 

We face competition from companies developing other and similar technologies that are competitive with our technologies, including in the standards-setting arena. Due to competition, our technologies may not find a viable commercial marketplace or, where applicable, be adopted by the relevant standards. In particular, increasing participation within standards-setting organizations has contributed to greater competition for influence within such organizations and for ultimately setting standards. In addition, in licensing our patent portfolio, we may compete with other companies, many of whom also claim to hold SEPs, for a share of the royalties that certain licensees may argue to be the total royalty that is supported by a certain product or products. In any device or piece of equipment that contains intellectual property, the manufacturer may need to obtain a license from multiple holders of intellectual property. To the extent that multiple parties all seek royalties on the same product, the manufacturers could claim to have difficulty in meeting the financial requirements of each patent holder.

***Royalties could decrease for future license agreements due to downward product pricing pressures and competition over patent royalties.*** 

Royalty payments to us under future license agreements could be lower than anticipated. Certain licensees and others in the wireless and consumer electronics industries, individually and collectively, are demanding that royalties for patents be lower than historic royalties and/or should be applied to royalty bases smaller than the selling price of an end product (such as the "smallest salable patent practicing unit"). There is also increasing downward pricing pressure on certain wireless products, including handsets, and other consumer electronics devices that we believe implement our patented inventions, and some of our royalties are tied to the pricing of these devices. In addition, a number of other companies also claim to hold patents that are essential with respect to products we aim to license. Demands by certain licensees to reduce royalties due to pricing pressure or the number of patent holders seeking royalties on these technologies could result in a decrease in the royalties we receive for use of our patented inventions, thereby decreasing future revenue and cash flow.

***Our technologies may not become patented, adopted by wireless or video standards or widely deployed.*** 

We invest significant resources in the development of advanced technology and related solutions. However, certain of our inventions that we believe will be employed in current and future products, including 5G, HEVC, VVC and others, are the subject of patent applications where no patent has been issued to us yet by the relevant patent issuing authorities. There is no assurance that these applications will issue as patents, either at all or with claims that would be required by products in the market currently or in the future. Our investments may not be recoverable or may not result in meaningful revenue if a sufficient number of our technologies are not patented and/or adopted by the relevant standards or if products based on the technologies in which we invest are not widely deployed. Competing technologies could reduce the opportunities for the adoption or deployment of technologies we develop. In addition, it is possible that in certain technology areas, such as in the IoT space, the adoption of proprietary systems could compete with or replace standards-based technology. It is also possible in certain technology areas, such as video coding and the IoT, that open source and/or purportedly royalty-free solutions such as AV1, VP-9 and OCF could compete with or replace proprietary standards-based technology. If the technologies in which we invest do not become patented, are not adopted by the relevant standards, or are not adopted by and deployed in the mainstream markets, at all or at the rate or within time periods that we expect, our business, financial condition and operating results could be adversely affected.

***Setbacks in defending and enforcing our patent rights could cause our revenue and cash flow to decline.*** 

Some third parties have challenged, and we expect will continue to challenge, the infringement, validity and enforceability of certain of our patents. In some instances, certain of our patent claims could be substantially narrowed or declared invalid, unenforceable, not essential or not infringed. For example, in limited cases, certain of our patents have been held invalid by courts in proceedings initiated by counterparties to our litigation proceedings. We cannot ensure that the validity and enforceability of our patents will be maintained or that our patents will be determined to be applicable to any particular product or standard. Moreover, third parties could and do attempt to circumvent certain of our patents through design changes. Any significant adverse findings as to the validity, infringement, enforceability or scope of our patents and/or any successful design-around of our patents could result in the loss of patent licensing revenue from existing licensees, through termination or modification of agreements or otherwise, and could substantially impair our ability to secure new patent licensing arrangements, either at all or on beneficial terms.

***Scrutiny by antitrust authorities may affect our strategies for patent prosecution, licensing and enforcement and may increase our costs of doing business and/or lead to monetary fines, penalties or other remedies or sanctions.*** 

Domestic and foreign antitrust authorities regularly review their policies with respect to the use of SEPs, including the enforcement of such patents against competitors and others. Such scrutiny has in the past resulted in enforcement actions against Qualcomm and other licensing companies, and could lead to additional investigations of, or enforcement actions against, us. Additionally, potential licensees may initiate antitrust complaints against us, such as the complaint that Disney recently filed against us. Such inquiries and/or enforcement actions could impact the availability of injunctive and monetary relief, which may adversely affect our strategies for patent prosecution, licensing and enforcement and increase our costs of operation. Such inquiries and/or enforcement actions could also result in monetary fines, penalties or other remedies or sanctions that could adversely affect our business and financial condition.

***We are subject to risks resulting from customer concentration.*** 

We earn a significant amount of our revenue from a limited number of licensees or customers, and we expect that a significant portion of our revenue will continue to come from a limited number of licensees or customers for the foreseeable future. For example, in 2025, Samsung, Apple, and vivo each comprised 10% or more of our consolidated revenue. Further, because of the limited number of licensees and potential licensees, any opportunistic behavior during license negotiations by a company or companies using our technology could create large exposure for us. In the event that we are unable to renew one or more of such license agreements at all or on terms that are favorable to us, our future revenue and cash flow could be materially adversely affected. In the event that one or more of our significant licensees or customers fail to meet their payment or reporting obligations (for example, due to a credit issue or in connection with a legal dispute or similar proceeding) under their respective license agreements, our future revenue and cash flow could be materially adversely affected. In addition, in the event that there is a material decrease in shipments of licensed products by one of our per-unit licensees, our revenue from such licensee could significantly decline and our future revenue and cash flow could be adversely affected.

Additionally, there is significant concentration in the wireless communications industry in general, and these trends may continue. For example, in 2025, Samsung, Apple, and Xiaomi collectively accounted for over 50% of worldwide smartphone shipments, and we anticipate a similar level of concentration in worldwide shipments for future years. Any further concentration or sale within the wireless industry among handset providers may reduce the number of licensing opportunities or, in some instances, result in the reduction, loss or elimination of existing royalty obligations. Further, if wireless carriers consolidate with companies that utilize technologies that are competitive with our technologies or that are not covered by our patents, we could lose market opportunities, which could negatively impact our revenue and financial condition.

***We may not be successful in growing our business inorganically, and any acquisitions or strategic reactions could create risk and/or fail to yield the anticipated benefits.*** 

We regularly seek to expand our business opportunities through targeted acquisitions, research partnerships, joint ventures and licensing platforms. We face intense competition within our industry and otherwise for acquisitions of high-quality businesses, technologies and assets. As such, even if we are able to identify an acquisition target that we would like to acquire, we may not be able to complete the acquisition on commercially reasonable terms, or at all. If we are not able to consummate any of these inorganic growth opportunities on a reasonable time frame, on terms that are attractive to us or at all, we may not be able to grow our business in line with our expectations.

------

<u>[**Table of Contents**](#ibb62662d68ca424983f0f56e1e5271de_7)</u>

Additionally, acquisitions or other strategic transactions may increase our costs, including but not limited to accounting and legal fees, and may not generate financial returns or result in increased adoption or continued use of our technologies or of any technologies we may acquire. The integration of acquired companies or businesses may result in significant challenges, including, among others: successfully monetizing any acquired technology, in particular outside of our core licensing programs; integrating new employees, technology and/or products; consolidating research and development operations; minimizing the diversion of management's attention from ongoing business matters; and consolidating corporate and administrative infrastructures. As a result, we may be unable to accomplish the integration smoothly or successfully. In addition, we cannot be certain that the integration of acquired companies, businesses, technology and/or intellectual property with our business will result in the realization of the full benefits that we anticipate will be realized from such acquisitions. For example, in October 2025, we acquired AI startup Deep Render, and we may not realize the benefits of the acquisition to the extent anticipated. Our plans to integrate and/or expand upon research and development programs and technologies obtained through acquisitions may result in products or technologies that are not adopted by the market, or the market may adopt solutions competitive to our technologies.

***Our revenue may be affected by the deployment of future-generation wireless standards in place of 3G, 4G and 5G technologies or future-generation video standards, by the timing of such deployment, or by the need to extend or modify certain existing license agreements to cover subsequently issued patents.*** 

We own an evolving portfolio of issued and pending patents related to 3G, 4G and 5G cellular technologies and non-cellular technologies including video coding technologies, and our patent portfolio licensing program for future-generation wireless standards or video coding standards may not be as successful in generating licensing income as our current licensing programs. If there is a delay in the standardization and/or deployment of future standards, our business and revenue could be negatively impacted.

The licenses that we grant under our patent license agreements typically only cover products designed to operate in accordance with specified technologies and that were manufactured or deployed or anticipated to be manufactured or deployed at the time of entry into the agreement. Also, we have patent license agreements with licensees that now offer for sale types of products that were not sold by such licensees at the time the patent license agreements were entered into and, thus, are not licensed by us. We do not derive patent licensing revenue from the sale of products by our licensees that are not covered by a patent license agreement. In order to grant a patent license for any such products, we will need to extend or modify our patent license agreements or enter into new license agreements with such licensees, and we may not be able to do so on terms acceptable to us or at all. Further, such extensions, modifications or new license agreements may adversely affect our revenue on the sale of products covered by the license prior to any extension, modification or new license.

***Our business and operations could suffer in the event of security breaches.*** 

Attempts by others to gain unauthorized access to information technology systems are becoming more sophisticated. These attempts, which in some cases could be related to industrial or other espionage, include covertly introducing malware to computers and networks and impersonating authorized users, among others. Advancements in technology, including artificial intelligence ("AI") and machine learning, may continue to change the way bad actors seek to gain unauthorized access and disrupt systems, thereby increasing the risks of security breaches. Material security events could also require public disclosure, which could further harm our business or reputation. We seek to detect and investigate all security incidents and to prevent their recurrence, but, in some cases, we might be unaware of an incident or its magnitude and effects. The increasing use of AI tools also exposes us to additional risks of security breach and information loss. While we have not identified any material incidents of unauthorized access to date, the theft, unauthorized use or publication of our intellectual property and/or confidential business or personal information (whether through a breach of our own systems or the breach of a system of a third party that provides services to us) could harm our competitive or negotiating positions, reduce the value of our investment in research and development and other strategic initiatives, compromise our patent enforcement strategies or outlook, damage our reputation or otherwise adversely affect our business. In addition, to the extent that any future security breach results in inappropriate disclosure of our employees', licensees', or customers' confidential and /or personal information, we may incur liability or additional costs to remedy any damages caused by such breach.

***We face risks from doing business and maintaining offices in international markets.*** 

A significant portion of our licensees, potential licensees and customers are international, and our licensees, potential licensees and customers sell their products to markets throughout the world. Accordingly, a significant portion of our revenue are derived from operations outside of the United States. In recent years, we have expanded, and we may continue to expand, our international operations, opening offices in China, France and Finland. Accordingly, we are subject to the risks and uncertainties of operating internationally. Our international operations could exacerbate the other risk factors we have identified, and we could be affected by a variety of uncontrollable and changing factors, including, but not limited to: difficulty in protecting our intellectual property in foreign jurisdictions; enforcing contractual commitments in foreign jurisdictions or against foreign corporations; government regulations, tariffs and other applicable trade barriers; biased enforcement of foreign laws and regulations to promote industrial or economic policies at our expense; retaliatory practices by foreign actors; currency control regulations; export license requirements and restrictions on the use of technology; social, economic and political instability; costly, time consuming and changing regulatory regimes; natural disasters, acts of terrorism, widespread illness and war; potentially adverse tax consequences; general delays in remittance of and difficulties collecting non-U.S. payments; foreign labor regulations; anti-corruption laws; public health issues; and difficulty in staffing and managing operations remotely. Managing operations and complying with relevant laws and regulations in China may be particularly complex, costly and time-consuming. We also are subject to risks specific to the individual countries in which we and our licensees, potential licensees and customers do business.

In addition, adverse movements in currency exchange rates may negatively affect our business due to a number of situations, including the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• If the effective price of products sold by our licensees were to increase as a result of fluctuations in the exchange rate of the relevant currencies, demand for the products could fall, which in turn would reduce our royalty revenue.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Assets or liabilities of our consolidated subsidiaries may be subject to the effects of currency fluctuations, which may affect our reported earnings.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Certain of our operating and investing costs, such as foreign patent prosecution, are based in foreign currencies. If these costs are not subject to foreign exchange hedging transactions, strengthening currency values in selected regions could adversely affect our near-term operating expenses, investment costs and cash flows. In addition, continued strengthening of currency values in selected regions over an extended period of time could adversely affect our future operating expenses, investment costs and cash flows.

***Our business is subject to evolving corporate governance and public disclosure regulations and expectations that could expose us to reputational risks and legal liability.*** 

There is significant focus from investors, customers and employees as well as other stakeholders concerning sustainability and governance matters. Current and prospective investors are utilizing this data to inform their decisions including investment and voting using a multitude of evolving score and rating frameworks. Additionally, public interest and legislative pressure related to public companies' sustainability, governance and related practices continue to grow and evolve. We actively manage these issues and have established and publicly announced certain goals, commitments, and targets which we may refine or expand further in the future. These goals, commitments, and targets reflect our current plans and aspirations and are not guarantees that we will be able to achieve them.

Additionally, we are subject to various sustainability related reporting standards, which are rapidly evolving, and which have resulted in, and are likely to continue to result in, increased compliance costs and management attention. In particular, we are subject to both California and European Union reporting regimes on emissions and climate-related risks. Tracking and reporting the required metrics is costly and demands substantial attention. If our governance and reporting practices fail to meet the expectations of any of our stakeholders' evolving standards, our reputation, brand and employee retention may be negatively impacted. If we do not adapt our strategy or execution quickly enough to meet the evolving expectations, our business, financial condition, results of operations and reputation could be adversely affected.

***Our industry is subject to rapid technological change, uncertainty and shifting market opportunities.*** 

Our success depends, in part, on our ability to define and keep pace with changes in industry standards, technological developments and varying customer requirements. Changes in industry standards and needs could adversely affect the development of, and demand for, our technology, rendering our technology currently under development obsolete and unmarketable. The rapid adoption of AI, including its use in video codecs and related technologies, and widespread use of AI tools and could accelerate these changes. The patents and applications comprising our portfolio have fixed terms, and, if we fail to anticipate or respond adequately to these changes through the development or acquisition of new patentable inventions, patents or other technology, we could miss a critical market opportunity, reducing or eliminating our ability to capitalize on our patents, technology solutions or both.

***Our commercialization, licensing and/or M&A activities could lead to patent exhaustion or implied license issues that could materially adversely affect our business.*** 

The legal doctrines of patent exhaustion and implied license may be subject to different judicial interpretations. Our commercialization or licensing of certain technologies and/or our M&A activities could potentially lead to patent exhaustion or implied license issues that could adversely affect our patent licensing program(s) and limit our ability to derive licensing revenue from certain patents under such program(s), whether through the assumption of license agreements that would result in our patents being captured by such agreements, the acquisition of a business that sells or licenses products that practice our patents, or otherwise. In the event of successful challenges by current or prospective licensees based on these doctrines that result in a material decrease to our patent licensing revenue, our financial condition and operating results may be materially adversely affected.

***Our use of open source software could materially adversely affect our business, financial condition, operating results and cash flow.*** 

Certain of our technology and our suppliers' technology may contain or may be derived from "open source" software, which, under certain open source licenses, may offer accessibility to a portion of a product's source code and may expose related intellectual property to adverse licensing conditions. Licensing of such technology may impose certain obligations on us if we were to distribute derivative works of the open source software. For example, these obligations may require us to make source code for derivative works available or license such derivative works under a particular type of license that is different from what we customarily use to license our technology. While we believe we have taken appropriate steps and employ adequate controls to protect our intellectual property rights, our use of open source software presents risks that, if we inappropriately use open source software, we may be required to re-engineer our technology, discontinue the sale of our technology, release the source code of our proprietary technology to the public at no cost or take other remedial actions, which could adversely affect our business, operating results and financial condition. There is a risk that open source licenses could be construed in a way that could impose unanticipated conditions or restrictions on our ability to commercialize our solutions, which could adversely affect our business, operating results and financial condition. In addition, developing open source products, while adequately protecting the intellectual property rights upon which our licensing business depends, may prove burdensome and time-consuming under certain circumstances, thereby placing us at a competitive disadvantage.

***We may have exposure to additional tax liabilities.*** 

We are a U.S. headquartered multinational company subject to complex and changing tax laws in the United States and foreign jurisdictions where we do business. Significant judgment is required in determining our worldwide provision of income taxes. As a U.S. multinational company, we are subject to examination by the Internal Revenue Service ("IRS") and other tax authorities, and we have ongoing tax audits in various jurisdictions. Any of these examinations could result in challenges to various positions we assert in our filings and could impact our tax liability, both for future and past tax years. Although we believe that our tax estimates are reasonable, the final determination of tax audits and any related legal proceedings could materially differ from amounts reflected in our income tax provisions and accruals. Due to governmental and regulatory delays, the timing of the resolution of certain of our open audits has been extended, creating additional uncertainty. If the final determination of any of our open audits materially differs from our estimates and accruals, our income tax provision, results of operations and cash flows in the period or periods in which that determination is made could be negatively affected. And, the timing of the resolution of these audits could impact our cash position.

Our tax rate could be adversely affected by several factors beyond our control, including changes in tax laws, regulations, interpretations, tax rates, assessments and any related tax, interest or penalties. If we are deemed to owe additional taxes, it could negatively impact our business, financial condition, and results of operations. For example, most of our income is taxable in the United States with a significant portion qualifying for preferential treatment as foreign-derived intangible income ("FDII"). Beginning in 2026, the effective tax rate for FDII will increase from 13% to 14%. Any reduction or elimination of the FDII deduction would negatively impact our business. In France, where we have substantial operations, we benefit from research tax credits applicable to French technology companies, including the Crédit Impôt Recherche (CIR). While we have historically benefited from the CIR, the French government has recently challenged our eligibility for portions of the CIR that they previously accepted. We believe our estimates are reasonable and consistent with the regulation, but if this challenge is successful and our eligibility for the CIR is reduced, it could adversely impact our results of operations and cash flows. The French government could also eliminate or reduce the CIR entirely, in which case our provision for income taxes, results of operations and cash flows would be adversely affected.

In July 2025 budget reconciliation bill H.R. 1, referred to as the One Big Beautiful Bill Act (the "OBBBA"), was signed into law. The OBBBA contains several changes to corporate taxation rules which may affect our business. These provisions, their interpretations, and other proposed changes to law could further impact our tax rate and cash flow in future years.

------

<u>[**Table of Contents**](#ibb62662d68ca424983f0f56e1e5271de_7)</u>

Additionally, any increase in tax rates or new tax legislation, or any new guidance or interpretations of the same, could expose us to additional tax liabilities. For example, the OECD Model Rules under Pillar Two introduced a minimum corporate tax rate of 15% on multinational enterprises with annual consolidated revenue exceeding €750 million in at least two of the prior four years, and beginning in 2026, we are subject to this minimum tax, which has been adopted by various jurisdictions where we do business, including France and the UK. This and any of the other factors described above could have an adverse impact on our provision for income taxes, cash flows, results of operations and business.

***Market projections and data are forward-looking in nature.*** 

Our strategy is based on our own projections and on analyst, industry observer and expert projections, which are forward-looking in nature and are inherently subject to risks and uncertainties. We utilize these projections in various ways, including key strategic decisions that we regularly make regarding the direction of our business, research and licensing efforts. The validity of their and our assumptions, the timing and scope of wireless markets, economic conditions, customer buying patterns, timeliness of equipment development, pricing of products, growth in wireless telecommunications services that would be delivered on wireless devices and availability of capital for infrastructure improvements could affect these predictions. Projections on the size of various markets may be inaccurate. In addition, market data upon which we rely is based on third party reports that may be inaccurate. The inaccuracy of any of these projections and/or market data could adversely affect our business prospects, operating results and financial condition.

***Our strategic decisions about our patent portfolio involve risks, and the anticipated benefits of such actions may not be realized.***

From time to time, we make strategic decisions about our patent portfolio, whether through a formal portfolio review or opportunistic dispositions. Cost savings expectations of any portfolio review are inherently uncertain and, therefore, we cannot provide assurance that we will achieve any expected, or any actual cost savings from any such action. Our portfolio review activities may place substantial demands on our management, which could lead to the diversion of management's attention from other business priorities. We may divest or abandon assets as part of efforts to optimize spending on our patent portfolio. Any assets that we divest could turn out to be more valuable than we had anticipated and we may not realize the anticipated benefits of any strategic decision about our patent portfolio. Due to cost constraints, we also regularly undertake strategic decisions in respect of where and how we file for patents. These decisions could later prove to be incorrect, which could ultimately harm our licensing potential or enforcement options, which could in turn harm our financial results and business prospects.

***Our business is subject to a variety of domestic and international laws, rules and policies and other obligations regarding data protection.*** 

We may be affected by existing and proposed laws and regulations, as well as government policies and practices related to cybersecurity, privacy and data protection. For example, the European General Data Protection Regulation ("GDPR"), the United Kingdom's GDPR, the California Consumer Privacy Act of 2018 and the California Privacy Rights Act of 2020 impose obligations on companies such as ours regarding the collection, use, retention, protection and processing of personal data. Additionally, in 2021, China adopted the Personal Information Protection Law ("PIPL"), which, together China's existing cyber and data securities regulations, have required and will continue to require significant investment and resources to ensure compliance. Complying with these and other privacy and cybersecurity regulations could cause us to incur substantial costs or require us to change our business practices. If we cannot implement an effective compliance mechanism for cross-border privacy and security matters, we may face increased exposure to regulatory actions, substantial fines and other penalties and damage to our reputation, any of which could have a material adverse effect on our business. Further, these areas are quickly changing, becoming increasingly stringent, and creating regulatory uncertainty. Our commercial and cybersecurity insurance policies may be insufficient to insure us against these risks, and future escalations in premiums and deductibles under these policies may render them cost-prohibitive.

**Risks Relating to Our Common Stock and our Convertible Notes** 

***Our operating results may fluctuate significantly, which could make our future results difficult to predict and could cause our operating results to fall below expectations.*** 

Our operating results may fluctuate from quarter to quarter as a result of a number of factors, many of which are outside of our control and may be difficult to predict. In particular, the timing of revenue recognition may cause our revenue and earnings to fluctuate, and there is significant judgment in the application of our revenue recognition principles. For example, accounting principles sometimes require us to recognize revenue before the actual amount is certain, which could add to uncertainty in our revenue guidance. The variability and unpredictability of our results of operations or other operating metrics could result in our failure to meet our expectations or those of industry or financial analysts. If we fail to meet or exceed such expectations for these or any other reasons, the market price of our common stock could fall substantially.

***Our stock repurchase program may not result in a positive return of capital to shareholders.*** 

Our stock repurchase program may not return value to shareholders as it was designed to do because the market price of the stock may decline below the levels at which we repurchased shares of stock. Stock repurchase programs are intended to deliver shareholder value over the long term, but stock price fluctuations can reduce the effectiveness of such programs. In addition, our Board of Directors could choose to suspend or terminate the stock repurchase program at any time or not to renew the program.

***Our shareholders may not receive the level of dividends provided for in our dividend policy or any dividend at all, and any decrease in or suspension of the dividend could cause our stock price to decline.*** 

Our dividend policy contemplates the payment of a regular quarterly cash dividend of $0.70 per share on our outstanding common stock. We expect to pay quarterly cash dividends on our common stock at the rate set forth in our current dividend policy. However, the dividend policy and the payment and timing of future cash dividends under the policy are subject to the final determination each quarter by our Board of Directors that (i) the dividend will be made in compliance with laws applicable to the declaration and payment of cash dividends, including Section 1551(b) of the Pennsylvania Business Corporation Law, and (ii) the policy remains in our best interests, which determination will be based on a number of factors, including our earnings, financial condition, capital resources and capital requirements, alternative uses of capital, restrictions imposed by any existing debt, economic conditions and other factors considered relevant by the Board of Directors. Given these considerations, our Board of Directors may increase or decrease the amount of the dividend at any time and may also decide to vary the timing of or suspend or discontinue the payment of dividends in the future. Any decrease in the amount of the dividend, or suspension or discontinuance of payment of a dividend, could cause our stock price to decline.

***Securities analyst coverage or lack of coverage may have a negative impact on our common stock's market price.*** 

The trading market for our common stock will depend, in part, on the research and reports that securities or industry analysts publish about us or our business. We do not have any control over these analysts. If securities or industry analysts stop their coverage of us or additional securities and industry analysts fail to cover us in the future, the trading price for our common stock would be negatively impacted. If any analyst or analysts who cover us downgrade our common stock, changes their opinion of our shares or publishes inaccurate or unfavorable research about our business, our stock price could decline. If any analyst or analysts cease coverage of us or fail to publish reports on us regularly, demand for our common stock could decrease and we could lose visibility in the financial markets, which could cause our stock price and trading volume to decline.

***Our indebtedness could adversely affect our business, financial condition and results of operations and our ability to meet our payment obligations under such indebtedness.*** 

Our total indebtedness as of December 31, 2025 was approximately $478 million. This level of debt could have significant consequences on our future operations, including: reducing the availability of our cash flow to fund working capital, capital expenditures, acquisitions and other general corporate purposes, and limiting our ability to obtain additional financing for these purposes; limiting our flexibility in planning for, or reacting to, and increasing our vulnerability to, changes in our business, the industry in which we operate and the general economy; and placing us at a competitive disadvantage compared to our competitors that have less debt or are less leveraged. Any of the above-listed factors could have an adverse effect on our business, financial condition and results of operations and our ability to meet our payment obligations under the 2027 Notes.

***The convertible note hedge transactions and warrant transactions that we entered into in connection with the offering of the 2027 Notes may affect the value of the such notes, and the market price of our common stock.*** 

In connection with the 2027 Notes issuance, we entered into convertible note hedge transactions with certain financial institutions (the "option counterparties") and sold warrants to the respective option counterparties. These transactions will be accounted for as an adjustment to our shareholders' equity. The convertible note hedge transactions are expected to reduce the potential equity dilution upon any conversion of the notes. The warrants will have a dilutive effect on our earnings per share to the extent that the market price of our common stock exceeds the applicable strike price of the warrants on any expiration date of the warrants. Given the trading price of our stock in recent months, dilution related to these instruments will be substantial, and the market could react negatively. In addition, the respective option counterparties (and/or their affiliates) may modify their respective hedge positions from time to time (including during any observation period related to a conversion of the notes) by entering into or unwinding various derivative transactions with respect to our common stock and/or by purchasing or selling our common stock in open market transactions and/or privately negotiated transactions. The potential effect, if any, of any of these transactions and activities on the market price of our common stock will depend in part on investor expectations and market conditions and cannot be ascertained at this time, but any of these activities could adversely affect the market price of our common stock.

------

<u>[**Table of Contents**](#ibb62662d68ca424983f0f56e1e5271de_7)</u>

***We are subject to counterparty risk with respect to the convertible note hedge transactions.*** 

The respective option counterparties are financial institutions or affiliates of financial institutions, and we will be subject to the risk that such option counterparties may default under the respective convertible note hedge transactions. Our exposure to the credit risk of the option counterparties is not secured by any collateral. If an option counterparty becomes subject to insolvency proceedings, we will become an unsecured creditor in those proceedings with a claim equal to our exposure at that time under the applicable convertible note hedge transactions. Our exposure will depend on many factors but, generally, the increase in our exposure will be correlated to the increase in our common stock market price and in volatility of our common stock. In addition, upon a default by an option counterparty, we may suffer adverse tax consequences and dilution with respect to our common stock. We can provide no assurance as to the financial stability or viability of the option counterparties.

***Provisions of the 2027 Notes could discourage an acquisition of us by a third party.*** 

Certain provisions of the 2027 Notes could make it more difficult or more expensive for a third party to acquire us. Upon the occurrence of certain transactions constituting a fundamental change under the indenture, holders of the notes will have the right, at their option, to require us to repurchase all of their applicable notes or any portion of the principal amount of the notes at a price of 100% of the principal amount of the notes being repurchased, plus accrued and unpaid interest. We may also be required to issue additional shares upon conversion in the event of certain fundamental change transactions. These provisions could limit the price that some investors might be willing to pay in the future for shares of our common stock.

***Anti-takeover provisions could delay and discourage takeover attempts that shareholders may consider to be favorable.***

Certain provisions of our amended and restated articles of incorporation and amended and restated bylaws and applicable provisions of Pennsylvania law may make it more difficult or impossible for a third party to acquire control of us or effect a change in our Board of Directors and management. Our amended and restated articles of incorporation and amended and restated bylaws, together with other applicable provisions of Pennsylvania law, could delay, defer or prevent a change of control or changes in our Board of Directors or management. Any delay or prevention of a change of control transaction or changes in our Board of Directors or management could deter potential acquirers or prevent the completion of a transaction in which our shareholders could receive a substantial premium over the then current market price for their shares of our common stock. For further discussion of such anti-takeover provisions, see the sections titled "Certain Provisions of Our Articles and Bylaws" and "Anti-Takeover Statutes" in the Description of InterDigital's Securities exhibit incorporated by reference as Exhibit 4.2 to this Annual Report on Form 10-K

**General Risk Factors** 

***We may not be able to attract and retain qualified employees.*** 

Competition for top talent is substantial. In order to be successful, we must attract, develop, and retain employees. Implementing our business strategy requires specialized engineering, business and operational talent, and these skills are in high demand among our competitors. The market for employees in our industry is extremely competitive, and competitors for talent have and could in the future attempt to hire our employees or employment candidates. Additionally, our equity compensation programs are a key element in our ability to attract and retain talent. The future value of these awards is uncertain and depends on our stock price performance over time, so their effectiveness, particularly for retentive purposes, is difficult to predict. Further, the increased availability of remote working arrangements has expanded the pool of companies that can compete for our employees and employment candidates. A number of such competitors for talent are significantly larger than us and may be able to offer compensation, benefits or work arrangements perceived as more desirable than what we are able to offer. If we are unable to recruit, retain, and motivate our employees, then we may not be able to innovate, execute on our strategy and grow our business as planned. Further, the cost and loss of efficiency related to turnover, particularly at senior levels, may be significant.

***Macroeconomic conditions may harm our business.*** 

A decline in economic conditions, such as a recession, economic downturn or inflationary conditions in the U.S. or elsewhere could adversely affect our business. In particular, inflation has remained high in the U.S. and globally. Trade tensions or restrictions on free trade could exacerbate these effects. A majority of our revenue is derived from patent license agreements that provide for fixed payments that were negotiated before the recent rise in inflation. An inflationary environment can increase our cost of labor, as well as our other operating costs, without a corresponding increase in our revenue, which may have a material adverse impact on our operating results and financial condition.

**<u>Item 1C.</u> &nbsp;&nbsp;&nbsp;&nbsp;*<u>CYBERSECURITY.</u>***

InterDigital employs a defense-in-depth security model that uses multiple, layered controls to protect our data, our customers' data, our infrastructure, and our employees. We embed data protection throughout our operations and technology programs and rely on a combination of preventive and detective measures to safeguard our assets and personnel.

InterDigital evaluates cybersecurity risks as part of our overall enterprise risk management. A cybersecurity steering committee of senior executives is responsible for assessing and managing cybersecurity risks. The steering committee meets semi-annually to evaluate any changes to the Company's exposure to cybersecurity risks, discuss potential mitigation plans and provide updates on mitigation efforts already underway. The Senior Director, Head of Cybersecurity & Networks, with over 20 years of experience and industry-recognized certifications, reports to the VP of Information Services and manages the cybersecurity team that leads the steering committee. This team monitors threat intelligence from internal and external sources and oversees processes for evaluating cybersecurity risks associated with third-party service providers.

The cybersecurity team maintains a comprehensive set of cybersecurity policies and standards. We continually assess and update our cybersecurity strategy through activities such as tabletop exercises to anticipate emerging threats and evolving risks. InterDigital provides quarterly cybersecurity awareness training, conducts an annual Cybersecurity Awareness Month campaign, and performs quarterly phishing simulations to support ongoing employee education and vigilance. We also engage independent third parties to evaluate our cybersecurity program, including annual multi-stage penetration testing of our IT environment.

The Audit Committee of our Board oversees risks associated with cybersecurity threats. Both the Audit Committee and the full Board receive quarterly updates on cybersecurity risks identified through our enterprise risk management processes. Our cybersecurity policies include an incident response framework that defines responsibilities, reporting procedures, and escalation paths to ensure timely and accurate response to security incidents. The framework specifies how and when the Executive Leadership Team, cybersecurity steering committee, and the Audit Committee are informed of potential incidents. The Vice President of Information Services and the Head of Cybersecurity also present summaries of recent incidents quarterly at a regular Audit Committee meeting.

Despite our extensive cybersecurity program, we may not be able to prevent or mitigate all cybersecurity incidents, any of which could have a material adverse effect on us. To date, cybersecurity threats have not materially affected our business strategy, results of operations, or financial condition. We identify nation-state-sponsored threat actors, increasingly sophisticated criminal cyber actors, and ransomware campaigns as top reasonably likely material risks. Theft, unauthorized use, or disclosure of our intellectual property or confidential business or personal information—whether through a breach of our systems or those of a third-party service provider—could harm our competitive position, diminish the value of our investments in research and development and other strategic initiatives, compromise our patent enforcement strategies, damage our reputation, or otherwise adversely affect our business. See Item 1A, "Risk Factors," for additional information regarding cybersecurity risks.

<u>[**Table of Contents**](#ibb62662d68ca424983f0f56e1e5271de_7)</u>

**Business**

InterDigital, Inc. ("InterDigital") is a global research and development company focused primarily on wireless, video, artificial intelligence ("AI"), and related technologies. We design and develop foundational technologies that enable connected, immersive experiences in a broad range of communications and entertainment products and services. We license our innovations worldwide to companies providing such products and services, including makers of wireless communications devices, consumer electronics, internet of things ("IoT") devices, cars and other motor vehicles and providers of cloud-based services such as video streaming. As a leader in wireless technology, our engineers have designed and developed a wide range of innovations that are used in wireless products and networks, from the earliest digital cellular systems to 5G and today's most advanced Wi-Fi technologies. We are also a leader in video processing and video encoding/decoding technology used in video-enabled products and services. Our AI research effort is focused on the intersection of AI with both wireless and video technologies.

InterDigital is one of the largest pure research and development and licensing companies in the world, with one of the most significant patent portfolios of fundamental wireless and video technologies. As of December 31, 2025, InterDigital's wholly owned subsidiaries held a portfolio of more than 38,000 patents and patent applications related to wireless communications, video coding, display technology, and other areas relevant to communications and entertainment products and services. Our portfolio includes numerous patents and patent applications that we believe are or may be essential to existing standards, or may become essential to future standards, established by many Standards Development Organizations ("SDOs"). We have contributed technology to wireless standards including the 3G, 4G, 5G, and the development of 6G cellular standards and the IEEE 802.11 suite of standards. We have contributed technology to video standards including standards established by ISO/IEC Moving Picture Expert Group (MPEG), the ITU-T Video Coding Expert Group (VCEG), the Joint Collaborative Team on Video Coding (JCT-VC) and the Joint Video Expert Team (JVET), among others. We also develop technologies and associated patents enabling high dynamic range (HDR) production, distribution and display solutions.

**Revenue** 

In 2025 and 2024, our total revenue was $834.0 million and $868.5 million, respectively, which includes $277.4 million and $460.1 million, respectively, of catch-up revenue as more fully discussed below. In 2025, fixed-fee agreements accounted for 93% of our revenue. These fixed-fee revenue are not affected by the related licensees' success in the market or the general economic climate. The majority of the remaining portion of our revenue was variable in nature due to the per-unit structure of the related license agreements.

Smartphone, CE, IoT/Auto, and Video Services are the Company's licensing programs. The Smartphone revenue grouping consists primarily of smartphones and also includes other wireless communication devices and infrastructure equipment, such as tablets, and base stations. The CE, IoT/Auto revenue grouping consists of consumer electronics and IoT products, such as televisions, laptops, gaming consoles, set-top boxes, streaming devices, and connected automobiles. We do not yet have revenue from Video Services but a Video Services grouping would consist of SVOD, AVOD, global pay-TV, video conferencing, cloud gaming, and other cloud-based services.

**New Agreements** 

During 2025, we entered into eight patent license agreements as discussed below.

*<u>Direct Licenses</u>*

In 2025, we signed new multi-year, worldwide, non-exclusive, royalty-bearing license agreements with two major Chinese smartphone vendors, vivo and Honor. As a result, we now have eight of the ten largest smartphone vendors based on shipments and approximately 85% of the entire global smartphone market under license.

In April 2025, we signed a new multi-year license agreement with HP Inc. The agreement licenses HP personal computers to InterDigital's Wi-Fi and video decoding technologies.

------

<u>[**Table of Contents**](#ibb62662d68ca424983f0f56e1e5271de_7)</u>

Additionally, we entered into device licenses covering our technologies with a significant social media company, along with Eaton, Seiko Solutions Inc., Sharp, and Teltronic.

*<u>Samsung Arbitration</u>*

In 2022, we agreed to renew our patent license agreement with Samsung and enter into binding arbitration to determine the final terms of the license. In 2023, we began recognizing revenue for Samsung at a conservative level consistent with the revenue we recognized from our patent license agreement that expired on December 31, 2022.

On July 28, 2025, a panel of International Chamber of Commerce arbitrators determined the royalties of the patent license agreement covering Samsung's products, other than digital televisions and computer display monitors which have been licensed under a separate agreement. The arbitration panel set the total royalties at $1.05 billion for the eight-year patent license, which commenced on January 1, 2023 and runs through December 31, 2030. Under this agreement, we now recognize approximately $131 million of recurring revenue per year, a 67% increase from the previous license agreement. In 2025, the agreement contributed $118 million of catch-up revenue due to a true-up of the $78 million per year we had been recognizing based on the level of our prior agreement from January 1, 2023 to June 30, 2025.

**Subsequent Agreements**

In January 2026, we signed a new patent license agreement with LG Electronics. The agreement licenses LG's digital TVs and computer display monitors under InterDigital´s joint licensing program with Sony and includes licenses to technologies including ATSC 3.0, Wi-Fi and video codecs.

In January 2026, we renewed a worldwide, non-exclusive, royalty bearing license with Xiaomi. The renewed license has a term of five years and covers the vendor's cellular products, including its smartphones and other cellular-enabled devices, under InterDigital's standard essential cellular, Wi-Fi, and HEVC patents.

**Expiration of License Agreements**

Five revenue-generating patent license agreements expired during 2025 and have not yet been renewed, including the Samsung TV agreement. These agreements contributed $31.7 million of recurring revenue in 2025.

These five licensees exclude a license with Xiaomi that also expired during 2025 but was renewed in January 2026 as noted above.

Fourteen revenue-generating patent license agreements are scheduled to expire by the end of 2026. These agreements contributed $15.0 million of recurring revenue in 2025.

We are actively working to renew these agreements on terms consistent with each licensee's market position and use of our technology.

**Notes, Hedge, and Warrant Transactions**

Refer to Note 10, "*Obligations*" within the Notes to the Consolidated Financial Statements included in Part II, Item 8 of this Form 10-K for definitions of capitalized terms used below.

*<u>2027 Notes and Related Note Hedge and Warrant Transactions</u>*

During 2025, the 2027 Notes had a dilutive impact of 4.1 million shares, which are offset from an economic standpoint by the 2027 Note Hedge Transactions and would result in no incremental shares being issued upon conversion. However, under Generally Accepted Accounting Principles in the United States ("GAAP"), we are required to exclude the impact of the shares received from the 2027 Note Hedge Transactions counterparties from the calculation of weighted-average diluted shares outstanding.

From the period January 1, 2024 through March 31, 2026, the holders of the 2027 Notes have the right, but not the obligation, to convert any portion of the principal amount of the 2027 Notes. In December 2025, certain holders elected to convert $80.0 million of principal, which will settle in first quarter 2026. The principal of the converted notes will be paid in cash and the remaining amount will be settled in shares. No incremental shares will be outstanding upon conversion due to the offsetting impact of a corresponding partial settlement of the 2027 Note Hedge Transactions.

As of December 31, 2025, 6.0 million warrants remain outstanding related to the 2027 Warrant Transactions at a weighted-average strike price of $105.67 per share, subject to adjustment, which mature on a net-share basis beginning September 2027 through April 2028. Refer to "*Financial Position, Liquidity, and Capital Resources — Convertible Notes*" for further information regarding how changes in our stock price would affect the number of shares issuable related to the 2027 Warrant Transactions. For example, if the share price was $350, we would issue 4.2 million of common shares related to the 2027 Warrant Transactions.

**Intellectual Property Rights Enforcement**

If we believe a party is required to license our patents in order to manufacture, use and/or sell certain products or services and such party refuses to do so, we typically offer such party to have royalties, or other terms, set by third party adjudicators (such as arbitrators). If the party refuses that offer and we believe they are unwilling to agree to a patent license on a fair, reasonable and non-discriminatory basis, we may have no other viable recourse but to institute legal action against them to enforce our patent rights. This legal action has typically taken the form of a patent infringement lawsuit or an administrative proceeding. In addition, we and our licensees, in the normal course of business, might seek to resolve disagreements as to the rights and obligations of the parties under the applicable license agreement through arbitration or litigation. Such legal actions ultimately may be decided by the presiding court, third party adjudicator, or a negotiated resolution between the parties.

We initiated litigation against Lenovo and OPPO to enforce our intellectual patent rights in 2019 and 2021, respectively. Through these patent infringement actions, we successfully negotiated resolutions that resulted in patent license agreements being reached with OPPO in 2024 and Lenovo, with respect to our HEVC patents only, in 2023. Additionally, in 2024 we entered into an arbitration agreement with Lenovo to determine the terms of a new patent license for our cellular and other technologies. As part of these agreements, we and both third parties agreed to dismiss all pending litigations between us, and accordingly all litigations with Lenovo and OPPO have been dismissed as of fourth quarter 2024. Currently, our open enforcement actions include proceedings with Transsion, Disney, and Amazon, and the arbitration proceedings with Lenovo. The Company anticipates that the arbitration hearing will occur before year end.

These matters are more fully discussed in Note 12, "*Litigation and Legal Proceedings*," to the Notes to Consolidated Financial Statements included below in Part II, Item 8 of this Form 10-K.

In 2025, our intellectual property enforcement costs decreased to $48.9 million, from $56.2 million in 2024. These costs represented 52% of our total licensing costs of $93.6 million in 2025. Intellectual property enforcement costs will vary depending upon activity levels, and it is likely they will continue to be a significant expense for us in the future.

**Cash and Short-Term Investments**

As of December 31, 2025, we had $1.3 billion of cash, restricted cash, and short-term investments and approximately $1.5 billion of cash payments due under contracted fixed price agreements, which includes our conservative estimates of the minimum cash receipts that we expect to receive under the Lenovo arbitration.

93% of our 2025 revenue comes from fixed-fee agreements. Such agreements often have prescribed payment schedules that are uneven and sometimes front-loaded, resulting in timing differences between when we collect the cash payments and recognize the related revenue.

The following table reconciles the timing differences between cash receipts and recognized revenue on a quarterly basis for each of the last two years, including the resulting operating cash flow (in thousands):

**Return of Capital**

In June 2014, our Board of Directors authorized a $300 million share repurchase program (the "Share Repurchase Program"). Subsequently our Board of Directors authorized additional increases to the program, most recently in December 2023, bringing the total authorization of the Share Repurchase Program to nearly $1.4 billion. Since 2014, we have repurchased $1.2 billion of shares at an average price of $62.50, adjusted for dividends. This amount includes the $199.9 million, excluding fees, expenses and excise tax, repurchased as part of the modified "Dutch auction" tender offer in 2023. As of December 31, 2025, there was $127.2 million remaining under the Share Repurchase Program authorization.

Since January 2014, we have paid $504.6 million in dividends, bringing our total return of capital over this period to more than $1.7 billion. In September 2025, we announced a second dividend increase during 2025, increasing the quarterly cash dividend by $0.10 per share to $0.70 per share. Combined with previous increases, we have increased the dividend by 75% since the start of 2024.

**Impact of Macroeconomic and Geopolitical Factors**

We have been actively monitoring the impact of the current macroeconomic environment in the U.S. and globally characterized by market volatility, inflation, supply chain issues, high interest rates, tariffs and other potential trade-related sanctions, and the potential for a recession. These market factors, as well as the impacts of the Ukraine-Russia, Middle East and other global conflicts, have not had a material impact on our business to date. However, if these conditions continue or worsen, they could have an adverse effect on our operating results and our financial condition.

**Comparability of Financial Results**

When comparing our 2025 financial results against the financial results of other periods, the following items should be taken into consideration:

***Revenue***

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**•** Our 2025 revenue includes $277.4 million of catch-up revenue primarily related to the Samsung arbitration decision and from the vivo, HP, and Honor patent license agreements entered into in 2025.

***Operating Expenses***

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In 2025, we incurred $7.4 million nonrecurring costs, which includes severance costs from executive and non-executive departures, litigation fee reimbursement, and costs associated with the acquisition of Deep Render.

**Critical Accounting Policies and Estimates**

Our consolidated financial statements are based on the selection and application of GAAP, which require us to make estimates and assumptions that affect the amounts reported in both our consolidated financial statements and the accompanying notes. Future events and their effects cannot be determined with absolute certainty. Therefore, the determination of estimates requires the exercise of judgment. Actual results could differ from these estimates and any such differences may be material to the financial statements. Our significant accounting policies are described in Note 2, "*Summary of Significant Accounting Policies and New Accounting Guidance*" within the Notes to the Consolidated Financial Statements included in Part II, Item 8 of this Form 10-K. We believe the accounting policies that are of particular importance to the portrayal of our financial condition and results and that may involve a higher degree of complexity and judgment in their application compared to others are those relating to revenue recognition, compensation, and income taxes. If different assumptions were made or different conditions existed, our financial results could have been materially different.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***Revenue Recognition***

We derive the vast majority of our revenue from patent licensing. 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 include multiple performance obligations. These agreements can include, without limitation, performance obligations related to the settlement of past patent infringement liabilities, patent and/or know-how licensing royalties on covered products sold by licensees, access to a portfolio of technology as it exists at a point in time, and access to a portfolio of technology at a point in time along with promises to provide any technology updates to the portfolio during the term.

In accordance with GAAP, we use a five-step model to achieve the core underlying principle that an entity should recognize revenue to depict the transfer of goods or services to customers at an amount that the entity expects to be entitled to in exchange for those goods or services. 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). Additionally, we have elected to utilize certain practical expedients in the application of ASC 606, *Revenue From Contracts with Customers*. In evaluating the presence of a significant financing component in our agreements, we utilize the practical expedient to exclude any contracts wherein the gap between payment by our customers and the delivery of our performance obligation is less than one year. We have also elected to utilize the practical expedient related to costs of obtaining a contract where an entity may recognize the incremental costs of obtaining a contract as an expense when incurred if the amortization period of the asset that the entity otherwise would have recognized is one year or less. Timing of revenue recognition may differ significantly from the timing of invoicing to customers. Contract assets represent unbilled amounts expected to be received from customers in future periods, where the revenue recognized to date exceeds the amount billed, and right to payment is subject to the underlying contractual terms. Contract assets due within less than twelve months of the balance sheet date are included within accounts receivable in our consolidated balance sheets. Contract assets are classified as long-term assets within other non-current assets if the payments are expected to be received more than one year from the reporting date.

For certain patent license agreements or other contractual arrangements, the amount of consideration that we will receive is uncertain. In such cases, we estimate and recognize licensing revenue only when we have a contract, as defined in the revenue recognition guidance. Such estimates are only recognized to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur. We analyze the risk of a significant revenue reversal considering both the likelihood and magnitude of the reversal and, if necessary, constrain the amount of estimated revenue in order to mitigate this risk, which may result in recognizing revenue less than amounts we expect we are most likely to receive. These aforementioned estimates may require significant judgment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***Patent License Agreements***

Upon signing a patent license agreement, we provide the licensee permission to use our patented inventions in specific applications. We account for patent license agreements in accordance with the guidance indicated above.

Certain patent license agreements contain revenue from non-financial sources in the form of patents received from the customer. Under our patent license agreements, we typically receive one or a combination of the following forms of payment as consideration for permitting our licensees to use our patented inventions in their applications and products.

*<u>Consideration for Past Patent Royalties</u>*

Consideration related to a licensee's product sales from prior periods may result from a negotiated agreement with a licensee that utilized our patented inventions prior to signing a patent license agreement with us or from the resolution of a disagreement or arbitration with a licensee over the specific terms of an existing license agreement. We may also receive consideration for past patent royalties in connection with the settlement of patent litigation where there was no prior patent license agreement. In each of these cases, we record the consideration as revenue as prescribed by the five-step model.

*<u>Fixed-Fee Agreements</u>*

Fixed-fee license agreements include fixed, non-refundable royalty payments that fulfill the licensee's obligations to us under a patent license agreement for a specified time period or for the term of the agreement for specified products, under certain patents or patent claims, for sales in certain countries, or a combination thereof - in each case for a specified time period (including for the life of the patents licensed under the agreement).

------

<u>[**Table of Contents**](#ibb62662d68ca424983f0f56e1e5271de_7)</u>

**Dynamic fixed-fee license agreements** contain a performance obligation that represents ongoing access to a portfolio of technology over the license term, since our promise to transfer to the licensee access to the portfolio as it exists at inception of the license, along with promises to provide any technology updates to the portfolio during the term, are not separately identifiable. We use a time-based input method of progress to determine the timing of revenue recognition, and as such we recognize the future deliverables on a straight-line basis over the term of the agreement. We utilize the straight-line method as we believe that it best depicts efforts expended to develop and transfer updates to the customer evenly throughout the term of the agreement.

**Static fixed-fee license agreements** are fixed-price contracts that generally do not include updates to technology we create after the inception of the license agreement or in which the customer does not stand to substantively benefit from those updates during the term. Although we have few static fixed-fee license agreements, we generally satisfy our performance obligations under such agreements at contract signing, and, as such, revenue is recognized at that time.

*<u>Variable Agreements</u>*

Upon entering a new variable patent license agreement, the licensee typically agrees to pay royalties or license fees on licensed products sold during the term of the agreement. We utilize the sales- or usage- based royalty exception for these agreements and recognize revenue during the contract term when the underlying sale or usage occurs. Our licensees under variable agreements typically provide us with quarterly royalty reports that summarize their sales of covered products and their related royalty obligations to us. We receive these royalty reports subsequent to the period in which our licensees' underlying sales occurred. As a result, we are required to estimate revenue and recognize sales-based royalties on such licensed products in the period in which the associated sales occur, considering all relevant information (historical, current and forecasted) that is reasonably available to us. Estimating licensees' quarterly royalties prior to receiving the royalty reports requires us to make assumptions and judgments related to forecasted trends and growth rates used to estimate our licensees' sales, which could have an impact on the amount of revenue we report on a quarterly basis. As a result of recognizing revenue in the period in which the licensees' sales occur using estimates, adjustments to revenue are required in subsequent periods to reflect changes in estimates as new information becomes available, including market information, royalty reports provided by our licensees, audit results, among others.

*<u>Hybrid Agreements</u>*

We enter into hybrid patent license agreements that include (i) a fixed-fee minimum guarantee and (ii) additional per-unit royalties for units sold in excess of the units covered by the minimum guarantee. Under these agreements, the fixed-fee component represents a minimum amount the licensee is required to pay and provides a license to our technologies up to a specified number of units sold, with incremental per-unit royalties due for units sold in excess of the unit cap. When a licensee's sales exceed the unit cap, we recognize revenue for the additional per-unit royalties in the periods in which we estimate the licensee has exceeded the minimum and adjust revenue based on actual usage once reported by the licensee. The fixed-fee, or minimum guarantee, portion of a hybrid agreement is recognized on the same basis as our other fixed-fee agreements, as described above. As a result of recognizing revenue in the period in which the licensees' sales occur using estimates, adjustments to revenue are required in subsequent periods to reflect changes in estimates as new information becomes available, including market information, royalty reports provided by our licensees, audit results, among others.

***Agreements with Multiple Performance Obligations***

During 2025, we signed new fixed-fee agreements that had multiple performance obligations. We allocated the transaction price to each performance obligation for accounting purposes using our best estimate of the term and value. The process for determining the value of the standalone selling prices of identified performance obligations in dynamic fixed-fee license agreements requires the exercise of significant judgment when evaluating the valuation methods and assumptions, including the assumed royalties, projected sales volumes, discount rate, identification of comparable market transactions which are not directly observable and other relevant factors. Changes in any of a number of these assumptions could have had a substantial impact on the relative fair value assigned to each performance obligation for accounting purposes. These inputs and assumptions represent management's best estimates at the time of the transaction.

The impact that a five percent change in the aggregate amount allocated to catch-up revenue under these agreements would have had on 2025 revenue is summarized in the following table (in thousands):

---

| | | |
|:---|:---|:---|
| | **Change in amount allocated** | **Change in amount allocated** |
| **Allocation to catch-up revenue** | **+5%** | **-5%** |
| Change in revenue | $11689 | $(11689) |

***Revenue from Non-financial Sources***

During 2025, 2024, and 2023, less than 1%, 2% and 3%, respectively, of our total revenue was based on the estimated fair value of non-financial consideration received, principally patents. The process for determining the value of revenue from non-financial sources requires estimating the fair value of patents received. We estimated the fair value of the patents in the above transactions using one of, or a combination of, an analysis of comparable market transactions (the market approach), a discounted cash flow analysis (the income approach) and/or by quantifying the amount of money required to replace the future service capability of the assets (the cost approach). For the market approach, judgment was applied as to which market transactions were most comparable to the transaction. For the income approach, the inputs and assumptions used to develop these estimates were based on a market participant perspective and included estimates of projected royalties, discount rates, economic lives and income tax rates, among others. For the cost approach, we utilized the historical cost of assets of similar technologies to determine the estimated replacement cost, including research, development, testing and patent application fees. The development of a number of these inputs and assumptions requires a significant amount of management judgment and is based upon a number of factors, including identification of comparable market transactions, assumed royalties, projected sales volumes, economic lives of the patents and other relevant factors. Changes in any of a number of these assumptions could have had a substantial impact on the fair value assigned to the patents for accounting purposes. These inputs and assumptions represent management's best estimates at the time of the transaction.

The impact that a five-percent change in the estimated aggregate value of the patents acquired would have had on 2025 revenue, patent amortization and pre-tax income is summarized in the following table (in thousands):

---

| | | |
|:---|:---|:---|
| | **Change in estimate** | **Change in estimate** |
| **Estimated value of patents acquired in connection with PLAs** | **+5%** | **-5%** |
| Revenue | $130 | $(130) |
| Less: Patent amortization | 664 | (664) |
| Pre-tax income | $(534) | $534 |

***Compensation Programs***

We use a variety of compensation programs to attract, retain and motivate our employees, and to align employee compensation more closely with company performance. These programs include, but are not limited to, short-term incentives tied to performance goals, cash awards to inventors for filed patent applications and patent issuances, and long-term incentives in the form of stock option awards, time-based restricted stock unit ("RSU") awards, performance-based RSU awards and cash awards, noting equity awards are granted pursuant to the terms and conditions of our Equity Plans (as defined within the Notes to the Consolidated Financial Statements included in Part II, Item 8 of this Form 10-K). Our long-term incentives, including equity awards, typically include annual equity or cash award grants with three to five year vesting periods; as a result, in any one year, we are typically accounting for at least three active cycles.

The aggregate amount of performance compensation expense we record in a period, under both short-term and long-term incentive compensation programs, requires the input of subjective assumptions and is a function of our estimated progress toward performance goals at both the beginning and the end of the period. Our estimated progress toward goals under performance equity grants is based on meeting a minimum confidence level of achievement in accordance with accounting rules for share-based compensation. Due to the uncertain nature of patent license agreements, performance awards with milestone goals are typically not expensed until the goal has been achieved. Achievement rates can vary by performance cycle and from period to period, resulting in variability in our compensation expense.

We account for compensation costs associated with share-based compensation based on the fair value of the instruments issued. The estimated value of stock options includes assumptions around expected life, stock volatility and dividends. For stock options considered to be "plain vanilla" options, the Company estimates the expected term based on the simplified method as prescribed by Staff Accounting Bulletin Topic 14. The simplified method was used because the Company does not believe it has sufficient historical exercise data to provide a reasonable basis for the expected term of its grants. In all periods, our policy has been to set the value of RSUs awards equal to the value of our underlying common stock on the date of measurement. For grants with graded vesting, we amortize the associated unrecognized compensation cost using an accelerated method. For grants that cliff vest, we amortize the associated unrecognized compensation cost on a straight-line basis over their vesting term. For awards containing performance conditions, we recognize compensation expense ratably over the vesting period when it is probable that the stated performance targets will be achieved and record cumulative adjustments in the period in which estimates change.

<u>[**Table of Contents**](#ibb62662d68ca424983f0f56e1e5271de_7)</u>

In the event of canceled awards, we adjust compensation expense recognized to date as they occur. Tax windfalls and shortfalls related to the tax effects of employee share-based compensation are included in our tax provision. On the consolidated statements of cash flows, tax windfalls and shortfalls related to employee share-based compensation awards are included within operating activities and cash paid to tax authorities for shares withheld are included within financing activities. The inclusion of windfalls and shortfalls in the tax provision could increase our earnings volatility between periods. Tax windfalls related to share-based compensation was windfalls of $7.4 million, $4.9 million, and $3.1 million for the years ended 2025, 2024, and 2023, respectively.

The below table summarizes our supplemental compensation expense for 2025, 2024 and 2023, in thousands:

| &nbsp;&nbsp;Time-based awards <sup>(a)</sup> | 27188 | 25499 | 26426 |
| &nbsp;&nbsp;Performance-based awards <sup>(a)</sup> | 16249 | 20756 | 10035 |
| Total supplemental compensation expense | $73668 | $73844 | $56241 |

***Income Taxes***

Income taxes are accounted for under the asset and liability method. Under this method, deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, and operating loss and tax credit carry forwards. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the consolidated statement of income in the period in which the change was enacted. A valuation allowance is recorded to reduce the carrying amounts of deferred tax assets if management has determined that it is more likely than not that such assets will not be realized.

In addition, the calculation of tax liabilities involves significant judgment in estimating the impact of uncertainties in the application of complex tax laws. We are subject to examinations by the U.S. IRS and other taxing jurisdictions on various tax matters, including challenges to various positions we assert in our filings. In the event that the IRS or another taxing jurisdiction levies an assessment in the future, it is possible the assessment could have a material adverse effect on our consolidated financial condition or results of operations.

The financial statement recognition of the benefit for an uncertain tax position is dependent upon the benefit being more likely than not to be sustainable upon audit by the applicable tax authority. If this threshold is met, the tax benefit is then measured and recognized at the largest amount that is greater than 50 percent likely of being realized upon ultimate settlement. In the event that the IRS or another taxing jurisdiction levies an assessment in the future, it is possible the assessment could have a material adverse effect on our consolidated financial condition or results of operations.

Between 2014 and 2025, we paid approximately $205.2 million in foreign taxes to foreign governments that have tax treaties with the U.S., for which we have claimed foreign tax credits against our U.S. tax obligations, and for which the tax treaty procedures are still open. It is possible that as a result of tax treaty procedures, the U.S. government may reach an agreement with the related foreign governments that will result in a partial refund of foreign taxes paid with a related reduction in our foreign tax credits. Due to foreign currency fluctuations, any such agreement could result in foreign currency gain or loss. If the matter had been resolved as of December 31, 2025, we would have recognized a loss up to $22.5 million based on exchange rates and prior competent authority resolutions.

The One Big Beautiful Bill Act (the "OBBBA") was signed into law on July 4th, 2025. The OBBBA contains significant tax law changes with various effective dates affecting business taxpayers. Among the tax law changes that will impact the Company relate to the timing and amount of certain tax deductions including FDII, depreciation expense, R&D expenditures and interest expense. The tax law changes did not have an impact on the tax provision in 2025.

On November 8, 2019, the Company received notification that its request for competent authority pertaining to Article 25 (Mutual Agreement Procedure) of the United States-Republic of Finland Income Tax Convention had been reviewed by the IRS and an agreement has been reached (the "Finland Competent Authority Proceeding"). As a result of this agreement, the Company does not anticipate any tax consequences.

In France, where we have substantial operations, we benefit from research tax credits applicable to French technology companies, including the Crédit Impôt Recherche ("CIR"). While we have historically benefited from the CIR, the French government has recently challenged our eligibility for portions of the CIR that they previously accepted. The Company received notification from the French Tax Authorities that the CIR credit on patent costs has been rejected for tax years 2019 and 2020. The Company has filed petitions in the Lower Court of Paris to litigate this matter. Between 2019 and 2025, the Company has recorded benefits totaling approximately $29 million for CIR credit on patent related costs.

**New Accounting Guidance**

Refer to Note 2, "*Summary of Significant Accounting Policies and New Accounting Guidance*" within the Notes to the Consolidated Financial Statements included in Part II, Item 8 of this Form 10-K for a discussion of recently issued accounting guidance.

**Legal Proceedings**

We are routinely involved in disputes associated with enforcement and licensing activities regarding our intellectual property, including litigations, arbitrations and other proceedings. These litigations, arbitrations and other proceedings are important means to enforce our intellectual property rights. We are a party to other disputes and legal actions not related to our intellectual property, but also arising in the ordinary course of our business. Refer to Note 12, "*Litigation and Legal Proceedings*," to the Notes to Consolidated Financial Statements included below in Part II, Item 8 of this Form 10-K for a description of our material legal proceedings.

**FINANCIAL POSITION, LIQUIDITY AND CAPITAL RESOURCES** 

Our primary sources of liquidity are cash, cash equivalents, and short-term investments, as well as cash generated from operations. We believe we have the ability to obtain additional liquidity through debt and equity financings. From time to time, we may engage in a variety of transactions to augment our liquidity position as our business dictates and to take advantage of favorable interest rate environments or other market conditions, including the incurrence or issuance of debt and the refinancing or restructuring of existing debt. Based on our past performance and current expectations, we believe our available sources of funds, including cash, cash equivalents, short-term investments, and cash generated from our operations, will be sufficient to finance our operations, capital requirements, debt obligations, existing stock repurchase program, dividend program, and other contractual obligations discussed below in both the short-term over the next twelve months, and the long-term beyond twelve months.

**Cash, cash equivalents, restricted cash, and short-term investments**

As of December 31, 2025 and 2024, we had the following amounts of cash, cash equivalents, restricted cash, and short-term investments (in thousands):

---

| | | | |
|:---|:---|:---|:---|
| | **December 31, 2025** | **December 31, 2024** | **Increase / (Decrease)** |
| Cash and cash equivalents | $738960 | $527360 | $211600 |
| Restricted cash included within prepaid and other current assets | 15308 | 24187 | (8879) |
| Short-term investments | 504200 | 430848 | 73352 |
| Total cash, cash equivalents, restricted cash, and short-term investments | $1258468 | $982395 | $276073 |

---

The net increase in cash, cash equivalents, restricted cash, and short-term investments was attributable to cash provided by operating activities of $544.5 million partially offset by cash used in financing activities of $201.4 million and cash used in investing activities of $79.7 million, excluding sales and purchases of short-term investments. Refer to the sections below for further discussion of these items.

**Cash flows from operations**

We generated the following cash flows from our operating activities in 2025 and 2024 (in thousands):

---

| | | | |
|:---|:---|:---|:---|
| | **Year Ended December 31,** | **Year Ended December 31,** | **Year Ended December 31,** |
| | **2025** | **2024** | **Increase / (Decrease)** |
| Cash flows provided by operating activities | $544450 | $271528 | $272922 |

---

------

<u>[**Table of Contents**](#ibb62662d68ca424983f0f56e1e5271de_7)</u>

Our cash flows provided by operating activities are principally derived from cash receipts from patent license agreements, offset by cash operating expenses and income tax payments. The $272.9 million change in net cash provided by operating activities was driven by higher cash receipts resulting from timing of cash receipts on existing agreements and new agreements, and was partially offset by higher foreign withholding tax payments on those cash receipts. Additionally, cash operating expenses were lower primarily due to lower revenue share and litigation costs. The table below sets forth the significant items comprising our cash flows provided by operating activities during the years ended December 31, 2025 and 2024 (in thousands):

---

| | | | |
|:---|:---|:---|:---|
| | **Year Ended December 31,** | **Year Ended December 31,** | **Year Ended December 31,** |
| | **2025** | **2024** | **Increase / (Decrease)** |
| **Total Cash Receipts** | $877641 | $673910 | $203731 |
| **Cash Outflows:** |  |  |  |
| &nbsp;&nbsp;&nbsp;&nbsp;Cash operating expenses <sup>(a)</sup> | (252302) | (313125) | 60823 |
| &nbsp;&nbsp;&nbsp;&nbsp;Income taxes paid <sup>(b)</sup> | (109131) | (67541) | (41590) |
| **Total cash outflows** | (361433) | (380666) | 19233 |
| **Other working capital adjustments** | 28242 | (21716) | 49958 |
| **Cash flows provided by operating activities** | $544450 | $271528 | $272922 |

---

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) Cash operating expenses include operating expenses less depreciation, amortization, and share-based compensation. Amount includes revenue share costs of $10.1 million and $81.3 million in 2025 and 2024, respectively.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Income taxes paid include foreign withholding taxes.

**Cash provided by or used in investing and financing activities**

Net cash used in investing activities in 2025 was $140.3 million, a $249.7 million change from $109.5 million net cash provided by investing activities in 2024. During 2025, we purchased $60.6 million of short-term marketable securities, net of sales, and capitalized $70.5 million of patent costs and property and equipment purchases. During 2024, we sold $156.7 million of short-term marketable securities, net of purchases, and capitalized $58.7 million of patent costs and property and equipment purchases. Additionally, we received $15.8 million of net cash receipts from the sales of our long-term strategic investments.

Net cash used in financing activities for 2025 was $201.4 million, a $70.9 million decrease from $272.4 million in 2024. The decrease was driven primarily by a $126.2 million payment made in 2024 upon the maturity of the 2024 Notes. The decrease was partially offset by increased cash outflows in 2025, including a $35.6 million increase in share repurchases, a $25.0 million increase in taxes withheld on restricted stock unit vestings due to a higher share price at vesting, and a $18.9 million increase in dividends paid following the incremental increases in the declared dividend from $0.40 to $0.70.

**Other**

Our combined short-term and long-term deferred revenue balance at December 31, 2025 was $329.6 million, a decrease of $30.5 million from December 31, 2024. Based on current license agreements, we expect the amortization of dynamic fixed-fee royalty payments to reduce the December 31, 2025 deferred revenue balance by $193.7 million over the next twelve months.

**Convertible Notes**

Refer to Note 10, "*Obligations*" in the Notes to the Consolidated Financial Statements included in Part II, Item 8 of this Form 10-K for definitions of the capitalized terms used in this section.

From January 1, 2024 through March 31, 2026, the holders of the 2027 Notes have the right, but not the obligation, to convert any portion of the principal amount of the 2027 Notes.

Our 2027 Notes are included in the diluted earnings per share ("diluted EPS") calculation using the if-converted method in accordance with GAAP. Under the if-converted method, we assume that conversion of convertible securities occurs at the beginning of the reporting period. The 2027 Notes are convertible into cash up to the aggregate principal amount of the 2027 Notes to be converted and any value in excess of the principal amount ("the conversion spread") may be settled in cash, shares of the Company's common stock, or a combination thereof. As the principal amount is required to be paid in cash and only the conversion spread may result in shares being issued, we only include the net number of incremental shares that would be issued upon conversion. We calculate the number of shares of our common stock issuable under the terms of the 2027 Notes based on the average market price of our common stock during the applicable reporting period and include that number in the weighted-average diluted shares outstanding for the period.

------

<u>[**Table of Contents**](#ibb62662d68ca424983f0f56e1e5271de_7)</u>

At the time we issued the 2027 Notes, we entered into the 2027 Call Spread Transactions that together were designed to have the economic effect of reducing potential dilution upon conversion of the 2027 Notes by, in effect, increasing the conversion price of the 2027 Notes on an economic basis. However, under GAAP, since the impact of the 2027 Note Hedge Transactions is anti-dilutive, we exclude from the calculation of diluted EPS the shares of our common stock that we would receive from the counterparties upon settlement of the 2027 Note Hedge Transactions.

During periods in which the average market price of our common stock is above the applicable conversion price of the 2027 Notes (initial conversion price of approximately $77.49 per share), or above the strike price of the warrants (weighted average strike price of $105.67 per share), the impact of conversion of the 2027 Notes or exercise of the warrants, as applicable, would be dilutive and such dilutive effect is reflected in diluted earnings per share. In those periods, we calculate the incremental shares associated with the 2027 Notes (under the if-converted method) or the warrants based on the average market price of our common stock during the period and include those incremental shares in weighted-average diluted shares outstanding.

Under the if-converted method, changes in the price per share of our common stock can have a significant impact on the number of shares that we must include in the diluted EPS calculation. As described in Note 10, "*Obligations*" in the Notes to the Consolidated Financial Statements included in Part II, Item 8 of this Form 10-K, the 2027 Notes are convertible into cash up to the aggregate principal amount of 2027 Notes to be converted and any remaining obligations may be settled in cash, shares of the Company's common stock or a combination thereof ("net share settlement"). Assuming net share settlement upon conversion, the following table illustrates how changes in our stock price would affect the shares issuable under the 2027 Notes and related warrant transactions, the incremental shares included in diluted EPS under the if-converted method ("Total Incremental Shares"), the shares deliverable to us under the 2027 Note Hedge Transactions, and the resulting net incremental shares, based on $460.0 million aggregate principal amount outstanding and approximately 6.0 million related warrants as of December 31, 2025 (in thousands):

&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)From the period January 1, 2024 through March 31, 2026, the holders of the 2027 Notes have the right, but not the obligation, to convert any portion of the principal amount of the 2027 Notes. We will pay cash up to the aggregate principal amount of the 2027 Notes to be converted, if any, and will pay cash, shares of our Common Stock, or a combination of cash and shares of our Common Stock for any conversion obligation in excess of the aggregate principal amount being converted at our election. In December 2025, holders elected to convert $80.0 million of principal, which will settle in first quarter 2026. The principal of the converted notes will be paid in cash and the remaining amount will be settled in shares. The remaining $380.0 million will be repaid upon maturity in 2027, unless earlier converted. Refer to Note 10, "Obligations," within the Notes to the Consolidated Financial Statements included in Part II, Item 8 of this Form 10-K for details of our 2027 Notes.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)Purchase obligations consist of agreements to purchase goods and services that are legally binding on us, as well as accounts payable. Our consolidated balance sheet as of December 31, 2025 includes a $13.5 million non-current liability for uncertain tax positions. The future payments related to uncertain tax positions have not been presented in the table above due to the uncertainty of the amounts and timing of cash settlement with the taxing authorities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)Refer to Note 11, "*Commitments*," within the Notes to the Consolidated Financial Statements included in Part II, Item 8 of this Form 10-K for details of our defined benefit plan obligations. Estimated future benefit payments included above are through 2030.

As discussed above we believe our available sources of funds, including cash, cash equivalents, short-term investments, and cash generated from our operations, will be sufficient to finance these contractual obligations discussed above in both the short-term over the next twelve months, and the long-term beyond twelve months.

As of December 31, 2025, we have a debt obligation of $17.9 million related to the Technicolor Patent Acquisition and due to the uncertainty regarding the timing and amount of future payments, the amounts are excluded from the contractual obligations table above. Additionally, we are subject to a revenue-sharing arrangement with Technicolor resulting from the Technicolor Acquisitions. There is no liability associated with the revenue-share agreement at December 31, 2025, as it is deemed not probable. Refer to Note 10, "*Obligations*," within the Notes to the Consolidated Financial Statements included in Part II, Item 8 of this Form 10-K for further information.

**RESULTS OF OPERATIONS**

**2025 Compared with 2024**

***Revenue***

The following table compares 2025 revenue to 2024 revenue (in thousands):

---

| | | | | |
|:---|:---|:---|:---|:---|
| | **Year Ended December 31,** | **Year Ended December 31,** | | |
| | **2025** | **2024** | **Increase/(Decrease)** | **Increase/(Decrease)** |
| Smartphone | $678855 | $597540 | $81315 | 14% |
| CE, IoT/Auto | 154631 | 268680 | (114049) | (42)% |
| Other | 529 | 2296 | (1767) | (77)% |
| &nbsp;&nbsp;&nbsp;&nbsp;Total Revenue | $834015 | $868516 | $(34501) | (4)% |
| Catch-up revenue <sup>(a)</sup>, included above | $277409 | $460069 | $(182660) | (40)% |

---

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)&nbsp;&nbsp;&nbsp;&nbsp;Catch-up revenue represents revenue associated with reporting periods prior to the execution of the license agreement.

Total revenue of $834.0 million decreased $34.5 million from 2024 primarily due to larger catch-up revenue in 2024 resulting primarily from the Samsung TV and OPPO agreements, as well as the Lenovo UK ruling and arbitration agreement, partially offset by catch-up revenue on the Samsung arbitration decision and the vivo agreement in 2025. This decrease was also offset by revenue from fifteen new patent license agreements signed in the last twenty-one months.

In 2025 and 2024, 61% and 79% of our total revenue was attributable to companies that individually accounted for 10% or more of our total revenue, respectively. In 2025 and 2024, the following licensees or customers accounted for 10% or more of our total revenue:

---

| | | |
|:---|:---|:---|

***Operating Expenses***

The following table summarizes the change in operating expenses by category (in thousands):

---

| | | | | |
|:---|:---|:---|:---|:---|
| | **Year Ended December 31,** | **Year Ended December 31,** | | |
| | **2025** | **2024** | **Increase/(Decrease)** | **Increase/(Decrease)** |
| Research and portfolio development | $211432 | $196903 | $14529 | 7% |
| Licensing | 93642 | 169239 | (75597) | (45)% |
| General and administrative | 68088 | 62862 | 5226 | 8% |
| Total operating expenses | $373162 | $429004 | $(55842) | (13)% |

---

Operating expenses decreased 13% to $373.2 million in 2025 from $429.0 million in 2024. The $55.8 million decrease in total operating expenses was primarily due to the following items (in thousands):

---

| | |
|:---|:---|
| | **Increase/(Decrease)** |
| Revenue share costs | $(71178) |
| Intellectual property enforcement | (12524) |
| Depreciation and amortization | 7618 |
| Severance costs | 6072 |
| Net litigation fee reimbursement | 5223 |
| Other | 8947 |
| Total decrease in operating expenses | $(55842) |

---

The $55.8 million decrease in operating expenses was driven by a $71.2 million reduction in revenue share costs, mainly related to the Samsung TV and TPV agreements signed in 2024, and a $12.5 million reduction in intellectual property enforcement costs, primarily due to resolutions of the OPPO, Lenovo UK, and Samsung matters. This decrease in intellectual property enforcement costs was partially offset by one-time net litigation fee reimbursements resulting in contra-expense of $4.4 million in 2024 compared to a $0.9 million charge in 2025. These decreased intellectual property and enforcement costs were also partially offset by increases related to the announced Disney and Amazon proceedings, which are expected to continue into 2026 and increase as these, and other matters, progress.

These decreases were offset by a $7.6 million increase in depreciation and amortization due to our increased patent portfolio and investments in internal infrastructure and a $6.1 million increase in severance costs from executive and non-executive departures.

*Research and portfolio development expense:* Research and portfolio development expense increased by $14.5 million compared to 2024 primarily resulting from the above-noted increase in depreciation and amortization and severance costs.

*Licensing expense:* Licensing expense decreased by $75.6 million compared to 2024 primarily resulting from the above-noted decreased revenue share and intellectual property enforcement costs, partially offset by the above-noted litigation fee reimbursements and severance costs.

*General and administrative expense:* General and administrative expense increased by $5.2 million compared to 2024 primarily due to the above noted increases in severance costs.

***Non-Operating Income (Expense), Net***

The following table compares 2025 non-operating income to 2024 non-operating expense (in thousands):

---

| | | | | |
|:---|:---|:---|:---|:---|
| | **Year Ended December 31,** | **Year Ended December 31,** | | |
| | **2025** | **2024** | **Change** | **Change** |
| Interest expense | $(39962) | $(45421) | $5459 | 12% |
| Interest and investment income | 40025 | 40395 | (370) | (1)% |
| Other | 8516 | (5070) | 13586 | 268% |
| Total non-operating income (expense), net | $8579 | $(10096) | $18675 | 185% |

---

------

<u>[**Table of Contents**](#ibb62662d68ca424983f0f56e1e5271de_7)</u>

Interest expense decreased $5.5 million due to lower expense related to significant financing components on our patent license agreements and a reduction due to the maturity of the 2024 Notes.

The change in Other was primarily due to a foreign currency translation net gain arising primarily from euro translation of our foreign subsidiaries of $4.7 million in 2025, compared to a $7.9 million foreign currency translation net loss in 2024.

***Income Taxes***

In 2025, based on the statutory federal tax rate net of discrete federal and state taxes, our effective tax rate is 13.4%, as compared to an effective tax of 16.5% in 2024. The decrease in the effective rate was primarily attributable the impact of a higher percentage of foreign derived intangible income deduction and increase in share-based compensation deductions.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our ability to successfully integrate Deep Render and to recognize the anticipated benefits of the transaction;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the failure of markets for our technologies to materialize to the extent that we expect;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our continued ability to develop new technologies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in our interpretations of, and assumptions and calculations with respect to the impact on us of, the One Big Beautiful Bill Act, the 2017 Tax Cuts and Jobs Act and other U.S. and non-U.S. tax laws and other tax matters;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the timing and impact of potential regulatory, administrative and legislative matters;

You should carefully consider these factors as well as the risks and uncertainties outlined in greater detail in Part I, Item 1A, of this Form 10-K before making any investment decision with respect to our common stock. These factors, individually or in the aggregate, may cause our actual results to differ materially from our expected and historical results.

**<u>Item 7A.</u>** &nbsp;&nbsp;&nbsp;&nbsp;***<u>QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.</u>***

**Cash, cash equivalents, restricted cash and short-term investments**

The primary objectives of our investment activities are to preserve principal and maintain liquidity while at the same time capturing a market rate of return. To achieve these objectives, we maintain our portfolio of cash, cash equivalents, restricted cash, and short-term and long-term investments in a variety of securities, including government obligations, corporate bonds, and commercial paper.

*Interest Rate Risk —* We invest our cash in a number of diversified high quality investment-grade fixed and floating rate securities with a fair value of $1,258.5 million as of December 31, 2025. Our exposure to interest rate risks is not significant due to the short average maturity, quality and diversification of our holdings. We do not hold any derivative, derivative commodity instruments, or other similar financial instruments in our investment portfolio. The risk associated with fluctuating interest rates is generally limited to our investment portfolio. We believe that a hypothetical 10% change in period-end interest rates would not have a significant impact on our results of operations or cash flows.

The following table provides information about our interest-bearing securities that are sensitive to changes in interest rates as of December 31, 2025. The table presents principal cash flows, weighted-average yield at cost and contractual maturity dates. Additionally, we have assumed that these securities are similar enough within the specified categories to aggregate these securities for presentation purposes.

| Average interest rate | 3.7% | 3.7% | 3.9% | —% | —% | —% | 3.7% |

---

Cash and cash equivalents and available-for-sale securities are recorded at fair value.

*Bank Liquidity Risk —* As of December 31, 2025, we had approximately $745.0 million in money market and operating accounts that are held with domestic and international financial institutions. The majority of these balances are held with domestic financial institutions. While we monitor daily cash balances in our operating accounts and adjust the cash balances as appropriate, these cash balances could be lost or become inaccessible if the underlying financial institutions fail or if they are unable to meet the liquidity requirements of their depositors. We have not incurred any losses and have had full access to our operating accounts to date.

*Foreign Currency Exchange Rate Risk —* We are exposed to limited risk from fluctuations in currencies, which might change over time as our business practices evolve, that could impact our operating results, liquidity and financial condition. We operate and invest globally. Adverse movements in currency exchange rates might negatively affect our business due to a number of situations. Currently, our international licensing agreements are typically made in U.S. dollars and are generally not subject to foreign currency exchange rate risk. We do not engage in foreign exchange hedging transactions at this time.

Between 2014 and 2025, we paid approximately $205.2 million in foreign taxes to foreign governments that have tax treaties with the U.S., for which we have claimed foreign tax credits against our U.S. tax obligations, and for which the tax treaty procedures are still open. It is possible that as a result of tax treaty procedures, the U.S. government may reach an agreement with the related foreign governments that will result in a partial refund of foreign taxes paid with a related reduction in our foreign tax credits. Due to foreign currency fluctuations, any such agreement could result in foreign currency gain or loss. If the matter had been resolved as of December 31, 2025, we would have recognized a loss up to $22.5 million based on exchange rates and prior competent authority resolutions.

*Investment Risk —* We are exposed to market risk as it relates to changes in the market value of our short-term and long-term investments in addition to the liquidity and creditworthiness of the underlying issuers of our investments. We hold a diversified investment portfolio, which includes, fixed and floating-rate, investment-grade marketable securities, mortgage and asset-backed securities and U.S. government and other securities. The instruments included in our portfolio meet high credit quality standards, as specified in our investment policy guidelines. This policy also limits our amount of credit exposure to any one issue, issuer and type of instrument. Given that the guidelines of our investment policy prohibit us from investing in anything but highly rated instruments, our investments are not subject to significant fluctuations in fair value due to the volatility of the credit markets and prevailing interest rates for such securities. Our marketable securities, consisting of government obligations, corporate bonds and commercial paper, are primarily classified as available-for-sale with a fair value of $513.4 million as of December 31, 2025.

*Equity Risk —* We are exposed to changes in the market-traded price of our common stock as it influences the calculation of earnings per share. In connection with the offering of the 2027 Notes, we entered into convertible note hedge transactions with option counterparties. We also sold warrants to the option counterparties. These transactions have been accounted for as an adjustment to our shareholders' equity. The convertible note hedge transactions are expected to reduce the potential equity dilution upon conversion of the 2027 Notes. The warrants will have a dilutive effect for any incremental shares issued upon settlement and on our earnings per share to the extent that the average market price of our common stock for a given reporting period exceeds the applicable strike price or conversion price of the warrants or convertible 2027 Notes.

**Report of Independent Registered Public Accounting Firm**

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

***Opinions on the Financial Statements and Internal Control over Financial Reporting***

We have audited the accompanying consolidated balance sheets of InterDigital, Inc. and its subsidiaries (the "Company") as of December 31, 2025 and 2024, and the related consolidated statements of income, of comprehensive income, of shareholders' equity and of cash flows for each of the three years in the period ended December 31, 2025, including the related notes and financial statement schedule listed in the accompanying index (collectively referred to as the "consolidated financial statements"). We also have audited the Company's internal control over financial reporting as of December 31, 2025, based on criteria established in *Internal Control - Integrated Framework* (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above 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 its cash flows for each of the three years in the period ended December 31, 2025 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025, based on criteria established in *Internal Control - Integrated Framework* (2013) issued by the COSO.

***Basis for Opinions***

The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Management's Annual Report on Internal Control over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on the Company's consolidated financial statements and on the Company's internal control over financial reporting based on our audits. 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 audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements 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 audits 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. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

***Definition and Limitations of Internal Control over Financial Reporting***

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

------

<u>[**Table of Contents**](#ibb62662d68ca424983f0f56e1e5271de_7)</u>

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 or procedures may deteriorate.

***Critical Audit Matters***

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 (i) relates to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters 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 a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

*Revenue Recognition – Determination of Standalone Selling Prices of Identified Performance Obligations in Dynamic Fixed-Fee License Agreements Entered Into During The Year*

As described in Notes 2 and 3 to the consolidated financial statements, dynamic fixed-fee license agreements include fixed, non-refundable royalty payments that fulfill the licensee's obligations to the Company under a patent license agreement for a specified time period or for the term of the agreement. Total revenue and catch-up revenue were $834 million and $277 million, respectively, for the year ended December 31, 2025, of which a significant portion relates to dynamic fixed-fee agreements entered into during the year. As disclosed by management, the process for determining the value of the standalone selling prices of identified performance obligations in dynamic fixed-fee license agreements requires the exercise of significant judgment when evaluating the valuation methods and assumptions, including the assumed royalties, projected sales volumes, discount rate, identification of comparable market transactions which are not directly observable and other relevant factors.

The principal considerations for our determination that performing procedures relating to the determination of standalone selling prices of identified performance obligations in dynamic fixed-fee license agreements entered into during the year is a critical audit matter are (i) the significant judgment by management when determining the value of standalone selling prices of identified performance obligations in dynamic fixed-fee license agreements and (ii) a high degree of auditor judgment, subjectivity and effort in performing procedures and evaluating management's significant assumptions related to assumed royalties and projected sales volumes.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to the revenue recognition process, including controls over the determination of standalone selling prices of identified performance obligations in dynamic fixed-fee license agreements. These procedures also included, among others, for a sample of dynamic fixed-fee license agreements (i) reading agreements entered into during the year; (ii) testing management's process for determining the value of standalone selling prices of identified performance obligations; (iii) evaluating the appropriateness of the valuation methods used; (iv) testing the completeness and accuracy of data used by management in the valuation methods; and (v) evaluating the reasonableness of management's significant assumptions related to assumed royalties and projected sales volumes. Evaluating the reasonableness of management's significant assumptions related to assumed royalties and projected sales volumes involved considering consistency with historical sales data.

**INTERDIGITAL, INC. AND SUBSIDIARIES**

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS**

**December 31, 2025** 

**1. BACKGROUND AND BASIS OF PRESENTATION**

InterDigital, Inc. ("InterDigital") is a global research and development company focused primarily on wireless, video, artificial intelligence ("AI"), and related technologies. We design and develop foundational technologies that enable connected, immersive experiences in a broad range of communications and entertainment products and services. We license our innovations worldwide to companies providing such products and services, including makers of wireless communications devices, consumer electronics, internet of things ("IoT") devices, cars and other motor vehicles and providers of cloud-based services such as video streaming. As a leader in wireless technology, our engineers have designed and developed a wide range of innovations that are used in wireless products and networks, from the earliest digital cellular systems to 5G and today's most advanced Wi-Fi technologies. We are also a leader in video processing and video encoding/decoding technology used in video-enabled products and services. Our AI research effort is focused on the intersection of AI with both wireless and video technologies.

***Principles of Consolidation***

The accompanying consolidated financial statements include all of our accounts and all entities in which we have a controlling interest and/or are required to be consolidated in accordance with Generally Accepted Accounting Principles in the United States ("GAAP"). All significant intercompany accounts and transactions have been eliminated in consolidation.

In determining whether we are the primary beneficiary of a variable interest entity and therefore required to consolidate, we apply a qualitative approach that determines whether we have both the power to direct the economically significant activities of the entity and the obligation to absorb losses of, or the right to receive benefits from, the entity that could potentially be significant to that entity. These considerations impact the way we account for our existing collaborative relationships and other arrangements. We continuously assess whether we are the primary beneficiary of a variable interest entity as changes to existing relationships or future transactions may result in us consolidating or deconsolidating our partner(s) to collaborations and other arrangements.

***Use of Estimates***

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from these estimates. If different assumptions were made or different conditions had existed, our financial results could have been materially different.

***Reclassifications***

Certain reclassifications have been made to prior year amounts to conform to the current year presentation.

**2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND NEW ACCOUNTING GUIDANCE**

***Foreign Currency Translation***

The functional currency of substantially all of the Company's wholly-owned subsidiaries is the U.S. dollar. Certain subsidiaries have monetary assets and liabilities that are denominated in a currency that is different than the functional currency. The gains and losses resulting from this remeasurement and translation of monetary assets denominated in a currency that is different than the functional currency are reflected in the determination of net income.

***Cash, Cash Equivalents, Restricted Cash and Marketable Securities***

We classify all highly liquid investment securities with original maturities of three months or less at date of purchase as cash equivalents. Cash that is held for a specific purpose and therefore not available to the Company for immediate or general business use is classified as restricted cash. Our investments are comprised of mutual and exchange traded funds, commercial paper, United States and municipal government obligations and corporate securities. Management determines the appropriate classification of our investments at the time of acquisition and re-evaluates such determination at each balance sheet date.

As of December 31, 2025 and 2024, the majority of our marketable securities have been classified as available-for-sale and are carried at fair value, with unrealized gains and losses reported net-of-tax as a separate component of shareholders' equity. Substantially all of our investments are investment grade government and corporate debt securities that have maturities of less than three years, and we have both the ability and intent to hold the investments until maturity.

***Other-than-Temporary Impairments***

We review our investment portfolio during each reporting period to determine whether there are identified events or circumstances that would indicate there is a decline in the fair value that is considered to be other-than-temporary. For non-public investments, if there are no identified events or circumstances that would have a significant adverse effect on the fair value of the investment, then the fair value is not estimated. If an investment is deemed to have experienced an other-than-temporary decline below its cost basis, we reduce the carrying amount of the investment to its quoted or estimated fair value, as applicable, and establish a new cost basis for the investment. We charge the impairment to the "*Other income, net"* line of our consolidated statements of income.

***Intangible Assets***

***Patents***

We capitalize external costs, such as filing fees and associated attorney fees, incurred to obtain issued patents and patent license rights. We expense costs associated with maintaining and defending patents subsequent to their issuance in the period incurred. We amortize capitalized patent costs for internally generated patents on a straight-line basis over 10 years, which represents the estimated useful lives of the patents. The ten-year estimated useful life for internally generated patents is based on our assessment of such factors as: the integrated nature of the portfolios being licensed, the overall makeup of the portfolio over time, and the length of license agreements for such patents. The estimated useful lives of acquired patents and patent rights, however, have been and will continue to be based on a separate analysis related to each acquisition and may differ from the estimated useful lives of internally generated patents. The average estimated useful life of acquired patents is 9.9 years. We assess the potential impairment to all capitalized net patent costs when events or changes in circumstances indicate that the carrying amount of our patent portfolio may not be recoverable.

***Goodwill***

Goodwill is recorded as the difference, if any, between the aggregate consideration paid for an acquisition and the fair value of the net tangible and identified intangible assets acquired under a business combination. We review impairment of goodwill annually on the first day of the fourth quarter or if circumstances indicate a triggering event has occurred. We first assess qualitative factors to determine whether it is more likely than not that the fair value of our one reporting unit is less than its carrying amount as a basis for determining whether a quantitative goodwill impairment test is necessary. If we conclude it is more likely than not that the fair value of the reporting unit exceeds its carrying amount, we need not perform the quantitative assessment.

If based on the qualitative assessment we believe it is more likely than not that the fair value of the reporting unit is less than its carrying value, a quantitative assessment test is required to be performed. This assessment requires us to compare the fair value of our reporting unit to its carrying value including allocated goodwill. We determine the fair value of our reporting units generally using a combination of the income and market approaches. The income approach is estimated through the discounted cash flow method based on assumptions about future conditions such as future revenue growth rates, new product and technology introductions, gross margins, operating expenses, discount rates, future economic and market conditions, and other assumptions. The market approach estimates the fair value of our equity by utilizing the market comparable method which is based on revenue multiples from comparable companies in similar lines of business. If the carrying value of our reporting unit exceeds the reporting unit's fair value, a goodwill impairment charge will be recorded for the difference up to the carrying value of goodwill.

The carrying value of goodwill was $24.1 million and $22.4 million as of December 31, 2025 and December 31, 2024, which was included within "*Other non-current assets, net*" in the consolidated balance sheets. No impairments were recorded during 2025, 2024 or 2023 as a result of our annual goodwill impairment assessment.

***Property and Equipment***

Property and equipment are stated at cost, less depreciation, amortization, and impairments. Depreciation and amortization of property and equipment are provided using the straight-line method. The estimated useful lives for computer equipment, computer software, engineering and test equipment, and furniture and fixtures are generally three to five years. Leasehold improvements are amortized over the lesser of their estimated useful lives or their respective lease terms, which are generally five to ten years. Buildings are being depreciated over twenty-five years. Expenditures for major improvements and betterments are capitalized, while minor repairs and maintenance are charged to expense as incurred. Upon the retirement or disposition of property and equipment, the related cost and accumulated depreciation or amortization are removed, and a gain or loss is recorded.

***Leases***

We determine if an arrangement is a lease at inception. Operating lease right-of-use assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease right-of-use assets and liabilities are recognized at commencement date, except short-term leases with an original term of 12 months or less, based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we generally use an incremental borrowing rate based on the estimated rate of interest for collateralized borrowing over a similar term of the lease payments at commencement date. The operating lease right-of-use assets also includes any lease payments made and excludes lease incentives. Lease expense is recognized over the expected term on a straight-line basis. Leases with a lease term of 12 months or less are accounted for using the practical expedient which allows for straight-line rent expense over the remaining term of the lease.

<u>[**Table of Contents**](#ibb62662d68ca424983f0f56e1e5271de_7)</u>

***Internal-Use Software Costs***

We capitalize costs associated with software developed for internal use that are incurred during the software development stage. Such costs are limited to expenses incurred after management authorizes and commits to a computer software project, believes that it is more likely than not that the project will be completed, the software will be used to perform the intended function with an estimated service life of two years or more, and the completion of conceptual formulation, design and testing of possible software project alternatives (the preliminary design stage). Costs incurred after final acceptance testing has been successfully completed are expensed. Capitalized computer software costs are amortized over the estimated service life.

All computer software costs capitalized to date relate to the purchase, development and implementation of engineering, accounting and other enterprise software.

***Impairment of Long-Lived Assets***

We evaluate long-lived assets for impairment when factors indicate that the carrying value of an asset may not be recoverable. When factors indicate that such assets should be evaluated for possible impairment, we review whether we will be able to realize our long-lived assets by analyzing the projected undiscounted cash flows in measuring whether the asset is recoverable.

***Revenue Recognition***

We derive the vast majority of our revenue from patent licensing. 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 include multiple performance obligations. These agreements can include, without limitation, performance obligations related to the settlement of past patent infringement liabilities, patent and/or know-how licensing royalties on covered products sold by licensees, access to a portfolio of technology as it exists at a point in time, and access to a portfolio of technology at a point in time along with promises to provide any technology updates to the portfolio during the term.

In accordance with GAAP, we use a five-step model to achieve the core underlying principle that an entity should recognize revenue to depict the transfer of goods or services to customers at an amount that the entity expects to be entitled to in exchange for those goods or services. 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). Additionally, we have elected to utilize certain practical expedients in the application of ASC 606, *Revenue From Contracts with Customers*. In evaluating the presence of a significant financing component in our agreements, we utilize the practical expedient to exclude any contracts wherein the gap between payment by our customers and the delivery of our performance obligation is less than one year. We have also elected to utilize the practical expedient related to costs of obtaining a contract where an entity may recognize the incremental costs of obtaining a contract as an expense when incurred if the amortization period of the asset that the entity otherwise would have recognized is one year or less. Timing of revenue recognition may differ significantly from the timing of invoicing to customers. Contract assets represent unbilled amounts expected to be received from customers in future periods, where the revenue recognized to date exceeds the amount billed, and right to payment is subject to the underlying contractual terms. Contract assets due within less than twelve months of the balance sheet date are included within accounts receivable in our consolidated balance sheets. Contract assets are classified as long-term assets within other non-current assets if the payments are expected to be received more than one year from the reporting date.

For certain patent license agreements or other contractual arrangements, the amount of consideration that we will receive is uncertain. In such cases, we estimate and recognize licensing revenue only when we have a contract, as defined in the revenue recognition guidance. Such estimates are only recognized to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur. We analyze the risk of a significant revenue reversal considering both the likelihood and magnitude of the reversal and, if necessary, constrain the amount of estimated revenue in order to mitigate this risk, which may result in recognizing revenue less than amounts we expect we are most likely to receive. These aforementioned estimates may require significant judgment.

***Patent License Agreements***

Upon signing a patent license agreement, we provide the licensee permission to use our patented inventions in specific applications. We account for patent license agreements in accordance with the guidance indicated above.

Certain patent license agreements contain revenue from non-financial sources in the form of patents received from the customer. Under our patent license agreements, we typically receive one or a combination of the following forms of payment as consideration for permitting our licensees to use our patented inventions in their applications and products.

------

<u>[**Table of Contents**](#ibb62662d68ca424983f0f56e1e5271de_7)</u>

*<u>Consideration for Past Patent Royalties</u>*

Consideration related to a licensee's product sales from prior periods may result from a negotiated agreement with a licensee that utilized our patented inventions prior to signing a patent license agreement with us or from the resolution of a disagreement or arbitration with a licensee over the specific terms of an existing license agreement. We may also receive consideration for past patent royalties in connection with the settlement of patent litigation where there was no prior patent license agreement. In each of these cases, we record the consideration as revenue as prescribed by the five-step model.

*<u>Fixed-Fee Agreements</u>*

Fixed-fee license agreements include fixed, non-refundable royalty payments that fulfill the licensee's obligations to us under a patent license agreement for a specified time period or for the term of the agreement for specified products, under certain patents or patent claims, for sales in certain countries, or a combination thereof - in each case for a specified time period (including for the life of the patents licensed under the agreement).

**Dynamic fixed-fee license agreements** contain a performance obligation that represents ongoing access to a portfolio of technology over the license term, since our promise to transfer to the licensee access to the portfolio as it exists at inception of the license, along with promises to provide any technology updates to the portfolio during the term, are not separately identifiable. We use a time-based input method of progress to determine the timing of revenue recognition, and as such we recognize the future deliverables on a straight-line basis over the term of the agreement. We utilize the straight-line method as we believe that it best depicts efforts expended to develop and transfer updates to the customer evenly throughout the term of the agreement.

**Static fixed-fee license agreements** are fixed-price contracts that generally do not include updates to technology we create after the inception of the license agreement or in which the customer does not stand to substantively benefit from those updates during the term. Although we have few static fixed-fee license agreements, we generally satisfy our performance obligations under such agreements at contract signing, and, as such, revenue is recognized at that time.

*<u>Variable Agreements</u>*

Upon entering a new variable patent license agreement, the licensee typically agrees to pay royalties or license fees on licensed products sold during the term of the agreement. We utilize the sales- or usage- based royalty exception for these agreements and recognize revenue during the contract term when the underlying sale or usage occurs. Our licensees under variable agreements typically provide us with quarterly royalty reports that summarize their sales of covered products and their related royalty obligations to us. We receive these royalty reports subsequent to the period in which our licensees' underlying sales occurred. As a result, we are required to estimate revenue and recognize sales-based royalties on such licensed products in the period in which the associated sales occur, considering all relevant information (historical, current and forecasted) that is reasonably available to us. Estimating licensees' quarterly royalties prior to receiving the royalty reports requires us to make assumptions and judgments related to forecasted trends and growth rates used to estimate our licensees' sales, which could have an impact on the amount of revenue we report on a quarterly basis. As a result of recognizing revenue in the period in which the licensees' sales occur using estimates, adjustments to revenue are required in subsequent periods to reflect changes in estimates as new information becomes available, including market information, royalty reports provided by our licensees, audit results, among others.

*<u>Hybrid Agreements</u>*

We enter into hybrid patent license agreements that include (i) a fixed-fee minimum guarantee and (ii) additional per-unit royalties for units sold in excess of the units covered by the minimum guarantee. Under these agreements, the fixed-fee component represents a minimum amount the licensee is required to pay and provides a license to our technologies up to a specified number of units sold, with incremental per-unit royalties due for units sold in excess of the unit cap. When a licensee's sales exceed the unit cap, we recognize revenue for the additional per-unit royalties in the periods in which we estimate the licensee has exceeded the minimum and adjust revenue based on actual usage once reported by the licensee. The fixed-fee, or minimum guarantee, portion of a hybrid agreement is recognized on the same basis as our other fixed-fee agreements, as described above. As a result of recognizing revenue in the period in which the licensees' sales occur using estimates, adjustments to revenue are required in subsequent periods to reflect changes in estimates as new information becomes available, including market information, royalty reports provided by our licensees, audit results, among others.

***Accounts Receivable***

Accounts receivable is presented net of allowance for doubtful accounts. Our accounts receivable consists mainly of trade receivables derived from fixed-fee license arrangements with contractual payment terms. The remaining material amounts of our accounts receivable are from variable patent license agreements, which primarily are paid on a quarterly basis. The provision for doubtful accounts reflects the current estimate of credit losses expected to be incurred over the life of the financial asset, based on historical experience, current conditions and reasonable forecasts of future economic conditions. Further, we evaluate the collectability of our accounts receivable and if there is doubt that we will collect the full amount, we will record a reserve specific to that customer's receivable balance. There was no provision for doubtful accounts as of December 31, 2025 or 2024.

***Investments in Other Entities***

We may make strategic investments in companies that have developed or are developing technologies that are complementary to our business. We made an accounting policy election for a measurement alternative for our equity investments that do not have readily determinable fair values, specifically related to our strategic investments in other entities. Under the alternative, our strategic investments in other entities without readily determinable fair values are measured at cost, less any impairment, plus or minus changes resulting from observable price changes in orderly transactions for an identical or similar investment of the same issuer, if any. On a quarterly basis, we monitor items such as our investment's financial position and liquidity, performance targets, business plans, and cost trends to assess whether there are any triggering events or indicators present that would be indicative of an impairment, or any other observable price changes as indicated above. We do not adjust our investment balance when the investee reports profit or loss.

Additionally, other investments may be accounted for under the equity method of accounting. Under this method, we initially record our investment in the stock of an investee at cost, and adjust the carrying amount of the investment to recognize our share of the earnings or losses of the investee after the date of acquisition. The amount of the adjustment is included in the determination of net income, and such amount reflects adjustments similar to those made in preparing consolidated statements including adjustments to eliminate intercompany gains and losses, and to amortize, if appropriate, any difference between our cost and underlying equity in net assets of the investee at the date of investment. The investment is also adjusted to reflect our share of changes in the investee's capital. Dividends received from an investee reduce the carrying amount of the investment. When there are a series of operating losses by the investee or when other factors indicate that a decrease in value of the investment has occurred which is other than temporary, we recognize an impairment equal to the difference between the fair value and the carrying amount of our investment.

The carrying value of our investments in other entities is included within "*Other non-current assets, net*" on our consolidated balance sheets. The carrying value of our investments in other entities as of December 31, 2025 and 2024 was $11.7 million and $19.9 million and, respectively, the majority of which are accounted for under the measurement alternative for equity investments described above.

***Collaborative Arrangements***

We record the elements of our collaboration agreements that represent joint operating activities in accordance with ASC 808, *Collaborative Arrangements* ("ASC 808"). Accordingly, the elements of our collaboration agreements that represent activities in which both parties are active participants, and to which both parties are exposed to the significant risks and rewards that are dependent on the commercial success of the activities, are recorded as collaborative arrangements. Generally, the classification of a transaction under a collaborative arrangement is determined based on the nature and contractual terms of the arrangement along with the nature of the operations of the participants. For transactions that are deemed to be a collaborative arrangement under ASC 808, costs incurred and revenue generated on sales to third parties will be reported in our consolidated statement of operations on a gross basis if the Company is deemed to be the principal in the transaction, or on a net basis if the Company is instead deemed to be the agent in the transaction, consistent with the guidance in ASC 606-10-55-36, *Revenue From Contracts with Customers - Principal Agent Considerations*.

***Deferred Charges***

Direct costs of obtaining a contract or fulfilling a contract in a transaction that results in the deferral of revenue may be either expensed as incurred or capitalized, depending on certain criteria. We made a policy election to utilize the practical expedient related to costs of obtaining a contract where an entity may recognize the incremental costs of obtaining a contract as an expense when incurred if the amortization period of the asset that the entity otherwise would have recognized is one year or less. If the amortization period is greater than one year, we capitalize direct costs incurred for the acquisition or fulfillment of a contract through the date of signing if they are directly related to a particular revenue arrangement and are expected to be recovered. The costs are amortized on a straight-line basis over the life of the patent license agreement.

------

<u>[**Table of Contents**](#ibb62662d68ca424983f0f56e1e5271de_7)</u>

For example, from time to time, we use sales agents to assist us in our licensing and/or patent sale activities. In such cases, we may pay a commission. The commission rate varies from agreement to agreement. Commissions are normally paid shortly after our receipt of cash payments associated with the patent license or patent sale agreements. We defer recognition of commission expense and amortize these expenses in proportion to our recognition of the related revenue. Commission expense is included within the "*Licensing"* line of our consolidated statements of income and was immaterial for the years presented.

Incremental direct costs incurred related to a debt financing transaction may be capitalized. In connection with our offering of the 2027 Notes and 2024 Notes, defined and discussed in detail within Note 10, "*Obligations"*, we incurred directly related costs. The debt issuance costs of the debt were capitalized as deferred financing costs and recorded as a direct reduction of the debt. These costs are being amortized over the term of the debt using the effective interest method and are included within the "*Interest expense"* line of our consolidated statements of income. No new debt issuance costs were incurred in 2025, 2024, or 2023. Deferred financing expense was $2.1 million, $2.2 million and $2.3 million in 2025, 2024, and 2023, respectively. The balance of unamortized deferred financing costs as of December 31, 2025 and 2024 was $3.2 million and $5.3 million, respectively.

***Research and Innovation Expenses***

Research and innovation expenditures are expensed in the period incurred, except certain software development costs that are capitalized between the point in time that technological feasibility of the software is established and when the product is available for general release to customers. We did not have any capitalized software costs related to research and development in any period presented. Research and Innovation expenses are included within "*Research and portfolio development*" expenses in the consolidated statements of income.

***Compensation Programs***

We use a variety of compensation programs to attract, retain and motivate our employees, and to align employee compensation more closely with company performance. These programs include, but are not limited to, short-term incentives tied to performance goals, cash awards to inventors for filed patent applications and patent issuances, and long-term incentives in the form of stock option awards, time-based restricted stock unit ("RSU") awards, performance-based RSU awards and cash awards, noting equity awards are granted pursuant to the terms and conditions of our Equity Plans (as defined in Note 13, "*Compensation Plans and Programs*"). Our long-term incentives, including equity awards, typically include annual equity and cash award grants with three to five year vesting periods; as a result, in any one year, we are typically accounting for at least three active cycles.

We account for compensation costs associated with share-based compensation based on the fair value of the instruments issued. The estimated value of stock options includes assumptions around expected life, stock volatility and dividends. For stock options considered to be "plain vanilla" options, the Company estimates the expected term based on the simplified method as prescribed by Staff Accounting Bulletin Topic 14. The simplified method was used because the Company does not believe it has sufficient historical exercise data to provide a reasonable basis for the expected term of its grants. In all periods, our policy has been to set the value of RSUs awards equal to the value of our underlying common stock on the date of measurement. For grants with graded vesting, we amortize the associated unrecognized compensation cost using an accelerated method. For grants that cliff vest, we amortize the associated unrecognized compensation cost on a straight-line basis over their vesting term. For awards containing performance conditions, we recognize compensation expense ratably over the vesting period when it is probable that the stated performance targets will be achieved and record cumulative adjustments in the period in which estimates change.

In the event of canceled awards, we adjust compensation expense recognized to date as they occur. Tax windfalls and shortfalls related to the tax effects of employee share-based compensation are included in our tax provision. On the consolidated statements of cash flows, tax windfalls and shortfalls related to employee share-based compensation awards are included within operating activities and cash paid to tax authorities for shares withheld are included within financing activities. The inclusion of windfalls and shortfalls in the tax provision could increase our earnings volatility between periods. Tax windfalls related to share-based compensation were of $7.4 million, $4.9 million, and $3.1 million for the years ended 2025, 2024, and 2023, respectively.

***Income Taxes***

Income taxes are accounted for under the asset and liability method. Under this method, deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, and operating loss and tax credit carry forwards. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the consolidated statement of income in the period in which the change was enacted. A valuation allowance is recorded to reduce the carrying amounts of deferred tax assets if management has determined that it is more likely than not that such assets will not be realized.

In addition, the calculation of tax liabilities involves significant judgment in estimating the impact of uncertainties in the application of complex tax laws. We are subject to examinations by the U.S. IRS and other taxing jurisdictions on various tax matters, including challenges to various positions we assert in our filings. In the event that the IRS or another taxing jurisdiction levies an assessment in the future, it is possible the assessment could have a material adverse effect on our consolidated financial condition or results of operations.

The financial statement recognition of the benefit for an uncertain tax position is dependent upon the benefit being more likely than not to be sustainable upon audit by the applicable tax authority. If this threshold is met, the tax benefit is then measured and recognized at the largest amount that is greater than 50 percent likely of being realized upon ultimate settlement. In the event that the IRS or another taxing jurisdiction levies an assessment in the future, it is possible the assessment could have a material adverse effect on our consolidated financial condition or results of operations.

***Treasury Stock***

We record the repurchase of our shares of common stock at cost based on the settlement date of the transaction. These shares are classified as treasury stock, which is a reduction to shareholders' equity. Treasury shares are included in authorized and issued shares, but excluded from outstanding shares. If the Treasury shares are retired, the excess of the par value is included with retained earnings.

In August 2022, the Inflation Reduction Act was enacted in the United States, which included, among other items, a 1% excise tax on certain net repurchases of our common stock after December 31, 2022. This excise tax on our share repurchases is recorded as a component of stockholders' equity, as treasury stock, or retained earnings if retired.

**New Accounting Guidance**

***Accounting Standards Update: Interim Reporting (Topic 270): Narrow-Scope Improvements***

In December 2025, the FASB issued ASU 2025-11 to amend the guidance in "Interim Reporting" (Topic 270). The update provides clarifications intended to improve the consistency and usability of interim disclosure requirements, including a comprehensive listing of required interim disclosures and a new disclosure principle for reporting material events occurring after the most recent annual period. The amendments do not change the underlying objectives of interim reporting but are designed to enhance clarity in application. The guidance is effective for fiscal years beginning after December 15, 2027, including interim periods within those fiscal years. We are currently evaluating the impact of adoption on our consolidated financial statements.

***Accounting Standards Update: Targeted Improvements to the Accounting for Internal-Use Software***

In September 2025, the FASB issued ASU No. 2025-06, "Intangibles—Goodwill and Other Internal-Use Software (Subtopic 350-40)". The amendments in the ASU amends certain aspects of the accounting for and disclosure of software costs under ASC 350-40. ASU 2025-06 is effective for fiscal years beginning after December 15, 2027, with early adoption allowed. We are currently evaluating the impact of adoption on our consolidated financial statements.

***Accounting Standards Update: Induced Conversions of Convertible Debt Instruments***

In November 2024, the FASB issued ASU No. 2024-04, "Debt—Debt with Conversion and Other Options (Subtopic 470-20): Induced Conversions of Convertible Debt Instruments". The amendments in the ASU require disclosures for determining whether certain settlements of convertible debt instruments should be accounted for as an induced conversion. ASU 2024-04 is effective for fiscal years beginning after December 15, 2025, with early adoption allowed. We are currently evaluating the impact of adoption on our consolidated financial statements.

***Accounting Standards Update: Disaggregation of Income Statement Expenses***

In November 2024, the FASB issued ASU No. 2024-03, "Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses". The amendments in the ASU require disclosures about specific types of expenses included in the expense captions presented on the Consolidated Statements of Income, as well as disclosures about selling expenses. ASU 2024-03 is effective for fiscal years beginning after December 15, 2026, with early adoption allowed. We are currently evaluating the impact of adoption on our financial disclosures.

***Accounting Standards Update: Improvements to Income Tax Disclosures***

In December 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Updates ("ASU") No. 2023-09, "Income Taxes (Topic 740): Improvements to Income Tax Disclosures". The amendments in the ASU enhance income tax disclosures, primarily through standardization, disaggregation of rate reconciliation categories, and income taxes paid by jurisdiction. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024, with early adoption allowed. We retrospectively adopted this guidance as of January 1, 2025, and included the necessary disclosures in this Form 10-K.

**3.&nbsp;&nbsp;&nbsp;&nbsp;REVENUE RECOGNITION**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)&nbsp;&nbsp;&nbsp;&nbsp;Catch-up revenue represents revenue associated with reporting periods prior to the execution of the license agreement.

During the year ended December 31, 2025, we recognized $178.0 million of revenue that had been included in deferred revenue as of the beginning of the period. As of December 31, 2025 and 2024, we had contract assets of $19.7 million and $162.8 million included within "*Accounts receivable, net*" in the consolidated balance sheet, respectively. As of December 31, 2025, we also had $21.0 million contract assets included within "*Other non-current assets, net*" in the consolidated balance sheet.

**Contracted Revenue**

Based on Dynamic Fixed-Fee Agreements as of December 31, 2025, we expect to recognize the following amounts of revenue over the term of such contracts (in thousands):

**4.&nbsp;&nbsp;&nbsp;&nbsp;SEGMENT AND CONCENTRATION INFORMATION**

***Segment Performance Measures and Expenses***

Our chief operating decision maker ("CODM"), who is the Chief Executive Officer, assesses company-wide performance and allocates resources based on consolidated financial information. Consequently, we view the entire organization as one reportable segment and the strategic purpose of all operating activities is to support that one segment. The CODM evaluates company-wide performance based on multiple performance measures, including, but not limited to, net income. Our CODM does not generally evaluate our performance using asset or historical cash flow information.

The table below provides the calculation of net income, which is the performance measure that is most consistent with GAAP, and the significant operating expenses included in this performance measure (in thousands):

***Customer and Geographic Concentration***

During 2025, 2024, and 2023, the majority of our revenue was derived from a limited number of licensees based outside of the United States, primarily in Asia. Substantially all of this revenue was paid in U.S. dollars and were not subject to any substantial foreign exchange transaction risk. The table below lists the countries of the headquarters of our licensees and customers and the total revenue derived from each country or region for the periods indicated (in thousands):

As of December 31, 2025 and 2024, the majority of our marketable securities are classified as available-for-sale and are carried at fair value, with unrealized gains and losses reported net-of-tax as a separate component of shareholders' equity. Substantially all of our investments are investment-grade government and corporate debt securities that have maturities of less than three years, and we have both the ability and intent to hold the investments until maturity. We recorded no other-than-temporary impairments during 2025, 2024, or 2023. The gross realized gains and losses on sales of marketable securities were not significant during the years ended December 31, 2025, 2024, and 2023.

As of December 31, 2025 and 2024, $371.9 million and $323.8 million, respectively, of our short-term investments had contractual maturities within one year. The remaining portions of our short-term investments had contractual maturities within one to three years.

**6. &nbsp;&nbsp;&nbsp;&nbsp;CONCENTRATION OF CREDIT RISK AND FAIR VALUE OF FINANCIAL ASSETS AND FINANCIAL LIABILITIES**

***Concentration of Credit Risk and Fair Value of Financial Instruments***

Financial instruments that potentially subject us to concentration of credit risk consist primarily of cash equivalents, short-term investments, and accounts receivable. We primarily place our cash equivalents and short-term investments in highly rated financial instruments and in United States government instruments.

Our accounts receivable are derived principally from patent license and technology solutions agreements. As of December 31, 2025 and 2024, three licensees comprised 55% and 84% of our accounts receivable balance, respectively. We perform ongoing credit evaluations of our licensees, who generally include large, multinational, wireless telecommunications equipment manufacturers. We believe that the book values of our financial instruments approximate their fair values.

***Fair Value Measurements***

We use various valuation techniques and assumptions when measuring the fair value of our assets and liabilities. We utilize market data or assumptions that market participants would use in pricing the asset or liability, including assumptions about risk and the risks inherent in the inputs to the valuation technique. This guidance established a hierarchy that prioritizes fair value measurements based on the types of input used for the various valuation techniques (market approach, income approach and cost approach). The levels of the hierarchy are described below:

------

Level 1 Inputs — Level 1 includes financial instruments for which quoted market prices for identical instruments are available in active markets.

Level 2 Inputs — Level 2 includes financial instruments for which there are inputs other than quoted prices included within Level 1 that are observable for the instrument such as quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets with insufficient volume or infrequent transactions (less active markets) or model-driven valuations in which significant inputs are observable or can be derived principally from, or corroborated by, observable market data, including market interest rate curves, referenced credit spreads and pre-payment rates.

Level 3 Inputs — Level 3 includes financial instruments for which fair value is derived from valuation techniques including pricing models and discounted cash flow models in which one or more significant inputs are unobservable, including the company's own assumptions. The pricing models incorporate transaction details such as contractual terms, maturity and, in certain instances, timing and amount of future cash flows, as well as assumptions related to liquidity and credit valuation adjustments of marketplace participants.

Our assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the valuation of financial assets and financial liabilities and their placement within the fair value hierarchy. We use quoted market prices for similar assets to estimate the fair value of our Level 2 investments.

***Non-recurring Fair Value Measurements***

*Investments in Other Entities*

As disclosed in Note 2, "*Summary of Significant Accounting Policies and New Accounting Guidance*", we made an accounting policy election to utilize a measurement alternative for equity investments that do not have readily determinable fair values, which applies to our long-term strategic investments in other entities. Under the alternative, our long-term strategic investments in other entities that do not have readily determinable fair values are measured at cost, less any impairment, plus or minus changes resulting from observable price changes in orderly transactions for an identical or similar investment of the same issuer. Any adjustments to the carrying value of those investments are considered non-recurring fair value measurements.

&nbsp;&nbsp;&nbsp;&nbsp;We recognized a net loss of $1.0 million during year ended December 31, 2025 and net gains of $2.0 million and $10.4 million during years ended 2024 and 2023, respectively resulting from observable price changes of our long-term strategic investments, which were included within "*Other income, net*" in the consolidated statement of income. Certain of our investments in other entities may be seeking additional financing in the next twelve months or potential exit strategies. We will continue to review and monitor our investments in other entities for any indications of an increase in fair value or impairment.

Convida Wireless is a variable interest entity. We determined that we were the primary beneficiary for accounting purposes and consolidated Convida Wireless through September 30, 2023. As of October 1, 2023, we determined that we no longer met the accounting criteria for consolidation, and accordingly, we deconsolidated Convida Wireless during fourth quarter 2023. Upon deconsolidation, we recorded our investment in Convida at fair value utilizing the income approach. Our investment in Convida Wireless is accounted for as an equity method investment in accordance with ASC 323 "Investments – Equity Method and Joint Ventures" and included within "Other non-current assets, net" in the consolidated balance sheet. During fourth quarter 2025, this entity was fully dissolved.

*Patents*

During 2025 and 2024, we entered into patent license agreements in which a portion of the future consideration was in the form of patents. We estimated fair value of the patents subject to the agreements to be $3.0 million and $10.0 million in 2025 and 2024, respectively, for determining the transaction price for revenue recognition purposes utilizing a combination of the market and cost approaches. The value will be amortized as a non-cash expense over the patents' estimated useful lives.

We estimated the fair value of the patents in these transactions using one of, or a combination of, an analysis of comparable market transactions (the market approach) and/or by quantifying the amount of money required to replace the future service capability of the assets (the cost approach). For the market approach, judgment was applied as to which market transactions were most comparable to the transaction. For the cost approach, we utilized the historical cost of assets of similar technologies to determine the estimated replacement cost, including research, development, testing and patent application fees.

In October 2025, we acquired Deep Render, an AI startup with a team of world-class AI experts focusing on video codecs for cash considerations. We believe the acquisition adds significant depth to our existing AI expertise and strengthens the company's leadership in video compression. The transaction also adds Deep Render's patent portfolio in AI-based video coding to our market-leading video portfolio. As part of the deal, a team of AI experts joined our Video Lab. Founded in London in 2018, Deep Render has pioneered the use of AI in video and image compression to change the way that video is processed and ultimately distributed to connected devices and services.

As part of the transaction, the vast majority of the acquired value was assigned to patents, with the remaining resulting in the recognition of goodwill. The goodwill is included in the "*Other non-current assets, net*" in the consolidated balance sheet.

The 3.50% Senior Convertible Notes due 2027 (the "2027 Notes") are convertible during the period January 1, 2024 through March 31, 2026 and therefore are classified as "*Current portion of long-term debt*" as of December 31, 2025 and 2024 in our consolidated balance sheet. In December 2025, certain holders elected to convert $80.0 million of principal, which will settle in first quarter 2026. The principal of the converted notes will be paid in cash and the remaining amount will be settled in shares. No incremental shares will be outstanding upon conversion due to the offsetting impact of a corresponding partial settlement of the 2027 Note Hedge Transactions.

There is no acceleration of the maturity of the 2027 Warrant Transactions as a result of holders electing conversion of the 2027 Notes. As of December 31, 2025, all 6.0 million of the warrants under the 2027 Warrant Transactions are outstanding with a weighted average strike price of $105.67 per share, subject to adjustment, and mature beginning September 2027 through April 2028.

**<u>2027 Notes, and Related Note Hedge and Warrant Transactions</u>**

On May 27, 2022 we issued $460.0 million in aggregate principal amount of the 2027 Notes. The net proceeds from the issuance of the 2027 Notes, after deducting the initial purchasers' transaction fees and offering expenses, were approximately $450.0 million. The 2027 Notes bear interest at a rate of 3.50% per year, payable in cash on June 1 and December 1 of each year, commencing on December 1, 2022, and mature on June 1, 2027, unless earlier redeemed, converted or repurchased.

------

<u>[**Table of Contents**](#ibb62662d68ca424983f0f56e1e5271de_7)</u>

The 2027 Notes will be convertible into cash up to the aggregate principal amount of the notes to be converted and in respect of the remainder, if any, of the Company's obligation in excess of the aggregate principal amount of the notes being converted, pay or deliver, as the case may be, cash, shares of the Company's common stock or a combination thereof, at the Company's election, at an initial conversion rate of 12.9041 shares of Common Stock per $1,000 principal amount of Notes (which is equivalent to an initial conversion price of approximately $77.49 per share). The conversion rate, and thus the conversion price, may be adjusted under certain circumstances, including in connection with conversions made following fundamental changes and under other circumstances as set forth in the indenture governing the 2027 Notes.

Prior to 5:00 p.m., New York City time, on the business day immediately preceding March 1, 2027, the notes will be convertible only under the following circumstances: (1) on any date during any calendar quarter (and only during such calendar quarter) beginning after September 30, 2022 if the closing sale price of the Common Stock was more than 130% of the applicable conversion price on each applicable trading day for at least 20 trading days (whether or not consecutive) in the period of the 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter; (2) if the Company distributes to all or substantially all holders of the Common Stock any rights, options or warrants (other than in connection with a stockholder rights plan prior to separation of such rights from the shares of the Common Stock) entitling them to purchase, for a period of 45 calendar days or less from the issuance date for such distribution, shares of Common Stock at a price per share less than the average closing sale price for the ten consecutive trading day period ending on, and including, the trading day immediately preceding the declaration date for such distribution; (3) if the Company distributes to all or substantially all holders of the Common Stock any cash or other assets, debt securities or rights to purchase the Company's securities (other than pursuant to a rights plan), which distribution has a per share value exceeding 10% of the closing sale price of the Common Stock on the trading day immediately preceding the declaration date for such distribution; (4) if the Company engages in certain corporate transactions as described in the indenture governing the 2027 Notes; (5) if the Company calls the notes for redemption, at any time prior to the close of business on the second scheduled trading day immediately preceding the redemption date; (6) during a specified period if a fundamental change (as defined in the indenture governing the 2027 Notes) occurs; or (7) during the five consecutive business day period following any five consecutive trading day period in which the trading price for the notes for each day during such five trading day period was less than 98% of the closing sale price of the Common Stock multiplied by the applicable conversion rate on each such trading day. Commencing on March 1, 2027, the notes will be convertible in multiples of $1,000 principal amount, at any time prior to 5:00 p.m., New York City time, on the second scheduled trading day immediately preceding the maturity date of the notes.

The Company may not redeem the notes prior to June 5, 2025. The Company may redeem for cash all or any portion of the notes, at the Company's option, on or after June 5, 2025, if the last reported sale price of the Common Stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive), including the trading day immediately preceding the date on which the Company provides notice of redemption, during any 30 consecutive trading day period ending on and including the trading day preceding the date on which the Company provides notice of redemption at a redemption price equal to 100% of the principal amount of the notes to be redeemed, plus any accrued and unpaid interest to, but excluding the redemption date.

If a fundamental change (as defined in the indenture governing the 2027 Notes) occurs, holders may require the Company to purchase all or a portion of their Notes for cash at a repurchase price equal to 100% of the principal amount of the notes to be repurchased, plus any accrued and unpaid interest to, but excluding, the fundamental change repurchase date.

The 2027 Notes are the Company's senior unsecured obligations and rank equally in right of payment with any of the Company's current and any future senior unsecured indebtedness, including its 2.00% senior convertible notes due 2024 (the "2024 Notes" and together with the 2027 Notes, the "Convertible Notes"). The 2027 Notes are effectively subordinated to all of the Company's future secured indebtedness to the extent of the value of the related collateral, and the 2027 Notes are structurally subordinated to indebtedness and other liabilities, including trade payables, of the Company's subsidiaries.

On May 24 and May 25, 2022, in connection with the offering of the 2027 Notes, we entered into convertible note hedge transactions (collectively, the "2027 Note Hedge Transactions") that cover, subject to customary anti-dilution adjustments, approximately 5.9 million shares of common stock, in the aggregate, at a strike price that initially corresponds to the initial conversion price of the 2027 Notes, subject to adjustment, and are exercisable upon any conversion of the 2027 Notes. The aggregate cost of the 2027 Note Hedge Transactions was $80.5 million.

Also on May 24 and May 25, 2022, we also entered into privately negotiated warrant transactions (collectively, the "2027 Warrant Transactions" and, together with the 2027 Note Hedge Transactions, the "2027 Call Spread Transactions"), whereby we sold warrants to acquire, subject to customary anti-dilution adjustments, approximately 6.0 million shares of common stock at a weighted average strike price of $106.22 per share, subject to adjustment. As consideration for the 2027 Warrant Transactions, we received aggregate proceeds of $43.7 million. The net cost of the 2027 Call Spread Transactions was $36.8 million, which was funded out of the net proceeds from the offering of the 2027 Notes.

------

<u>[**Table of Contents**](#ibb62662d68ca424983f0f56e1e5271de_7)</u>

***Accounting Treatment of the 2027 Notes and Related Convertible Note Hedge and Warrant Transactions***

The 2027 Call Spread Transactions were classified as equity and the 2027 Notes were classified as long-term debt. The effective interest rate is approximately 4.02%.

In connection with the above-noted transactions, the Company incurred approximately $9.9 million of directly related costs, which were capitalized as deferred financing costs and as a reduction of long-term debt. These costs are being amortized as interest expense over the term of the debt using the effective interest method.

**<u>2024 Senior Convertible Notes, and Related Note Hedge and Warrant Transactions</u>**

On June 3, 2019 we issued $400.0 million in aggregate principal amount of 2.00% Senior Convertible Notes due 2024 (the "2024 Notes"). The net proceeds from the issuance of the 2024 Notes, after deducting the initial purchasers' transaction fees and offering expenses, were approximately $391.6 million. The 2024 Notes bore interest at a rate of 2.00% per year, payable in cash on June 1 and December 1 of each year, commenced on December 1, 2019, and matured on June 1, 2024.

In connection with the offering of the 2024 Notes, we entered into convertible note hedge transactions (collectively, the "2024 Note Hedge Transactions") that cover, subject to customary anti-dilution adjustments, approximately 4.9 million shares of common stock, in the aggregate, at a strike price that corresponded to the initial conversion price of the 2024 Notes, subject to adjustment, and were exercisable upon any conversion of the 2024 Notes.

We also entered into privately negotiated warrant transactions (collectively, the "2024 Warrant Transactions" and, together with the 2024 Note Hedge Transactions, the "2024 Call Spread Transactions"), whereby we sold warrants to acquire, subject to customary anti-dilution adjustments, approximately 4.9 million shares of common stock at an initial strike price of $109.43 per share, subject to adjustment.

In 2022, the Company repurchased $273.8 million in aggregate principal amount of the 2024 Notes in privately negotiated transactions concurrently with the offering of the 2027 Notes. We specifically negotiated the repurchase of the 2024 Notes with investors who concurrently purchased the 2027 Notes, such that their purchase of the 2027 Notes funded our repurchase of the 2024 Notes.

Additionally, in connection with the partial repurchase of the 2024 Notes, the Company entered into partial unwind agreements that amended the terms of the 2024 Note Hedge Transactions to reduce the number of options corresponding to the principal amount of the repurchased 2024 Notes. The unwind agreements also reduce the number of warrants exercisable under the 2024 Warrant Transactions. As a result of the partial unwind transactions, approximately 3.3 million shares of common stock in the aggregate that were covered under each of the 2024 Note Hedge Transactions and the 2024 Warrant Transactions were unwound.

On June 1, 2024, the 2024 Notes matured and we repaid the remaining $126.2 million in aggregate principal in cash and issued 0.3 million common shares to settle the remaining obligation. This issuance was effectively offset by our receipt of 0.3 million shares from the settlement of the 2024 Note Hedge Transactions. Additionally, the 2024 Warrant Transactions settled, on a net-share basis during September through December 2024 resulting in the issuance of 0.5 million shares.

**<u>Madison Arrangement</u>**

In conjunction with the Technicolor Patent Acquisition, we assumed Technicolor's rights and obligations under the Madison Arrangement, which commenced in 2015. The Madison Arrangement falls under the scope of ASC 808, *Collaborative Arrangements.*

------

<u>[**Table of Contents**](#ibb62662d68ca424983f0f56e1e5271de_7)</u>

Under the Madison Arrangement, Technicolor and Sony combined portions of their respective digital TV ("DTV") and computer display monitor ("CDM") patent portfolios and created a combined licensing opportunity to DTV and CDM manufacturers. Per an Agency and Management Services Agreement ("AMSA") entered into upon the creation of the Madison Arrangement, Technicolor was initially appointed as sole licensing agent of the arrangement, and InterDigital has now assumed that role. As licensing agent, we are responsible for making decisions regarding the prosecution and maintenance of the combined patent portfolio and the licensing and enforcement of the combined patent portfolio in the field of use of DTVs and CDMs on an exclusive basis during the term of the AMSA in exchange for an agent fee.

We were deemed to be the principal in this collaborative arrangement under ASC 808, and, as such, in accordance with ASC 606-10-55-36, *Revenue From Contracts with Customers - Principal Agent Considerations*, we record revenue generated on sales to third parties and costs incurred on a gross basis in the consolidated statements of income. Therefore, we recognize all royalties from customers as revenue and payments to Sony for its royalty share as operating expenses within the consolidated statements of income. Cost reimbursements for expenses incurred resulting from fulfilling the duties of the licensing agent are recorded as contra expenses. During the years ended December 31, 2025, 2024, and 2023, gross revenue recorded related to the Madison Arrangement were $41.7 million, $209.5 million, and $12.3 million, respectively. Net operating expenses related to the Madison Arrangement during the years ended December 31, 2025, 2024, and 2023 were $15.7 million, $84.1 million and $6.2 million, including $10.1 million, $81.3 million, and $3.3 million related to revenue sharing, respectively, and are reflected primarily within "*Licensing*" expenses in the consolidated statement of income.

*Long-term debt*

An affiliate of CPPIB Credit Investments Inc. ("CPPIB Credit"), a wholly owned subsidiary of Canada Pension Plan Investment Board, is a third-party investor in the Madison Arrangement. CPPIB Credit has made certain payments to Technicolor and Sony and has agreed to contribute cash to fund certain capital reserve obligations under the arrangement in exchange for a percentage of future revenue, specifically through September 11, 2030 in regard to the Technicolor patents.

Upon our assumption of Technicolor's rights and obligations under the Madison Arrangement, our relationship with CPPIB Credit met the criteria in ASC 470-10-25, *Sales of Future Revenue or Various Other Measures of Income* ("ASC 470"), which relates to cash received from an investor in exchange for a specified percentage or amount of revenue or other measure of income of a particular product line, business segment, trademark, patent, or contractual right for a defined period. Under this guidance, we recognized the fair value of our contingent obligation to CPPIB Credit, as of the acquisition date, as long-term debt in our consolidated balance sheet. This initial fair value measurement was based on the perspective of a market participant and includes significant unobservable inputs which are classified as Level 3 inputs within the fair value hierarchy. The fair value of the long-term debt as of December 31, 2025 is disclosed within Note 6, "*Concentration of Credit Risk and Fair Value of Financial Assets and Financial Liabilities"*. Our repayment obligations are contingent upon future royalty revenue generated from the Madison Arrangement and there are no minimum or maximum payments under the arrangement.

Under ASC 470, amounts recorded as debt shall be amortized under the interest method. At each reporting period, we review the discounted expected future cash flows over the life of the obligation. The Company made an accounting policy election to utilize the catch-up method when there is a change in the estimated future cash flows, whereby we will adjust the carrying amount of the debt to the present value of the revised estimated future cash flows, discounted at the original effective interest rate, with a corresponding adjustment recognized as interest expense within "*Interest expense*" in the consolidated statements of income. The effective interest rate as of the acquisition date was approximately 14.5%. This rate represents the discount rate that equates the estimated future cash flows with the fair value of the debt as of the acquisition date, and is used to compute the amount of interest to be recognized each period based on the estimated life of the future revenue streams. During the years ended December 31, 2025 and 2024, we recognized a $2.3 million and $3.5 million interest expense within "*Interest expense*" in the consolidated statements of income. During the year ended December 31, 2023, we recognized a $1.6 million net reduction of interest expense due to a change in estimate resulting from updated estimated cash outflows owed under the arrangement which is included within "*Interest expense*" in the consolidated statements of income. Any future payments made to CPPIB Credit, or additional proceeds received from CPPIB Credit, will decrease or increase the long-term debt balance accordingly.

*Restricted cash*

Under the Madison Arrangement, the parties reserve cash in bank accounts to fund our activities to manage the portfolios. These accounts are custodial accounts for which the funds are restricted for this purpose. As of December 31, 2025 and 2024, the Company had $15.3 million and $24.2 million, respectively, of restricted cash included within the consolidated balance sheet attributable to the Madison Arrangement. Refer to Note 5, "*Cash, Cash Equivalents, Restricted Cash and Marketable Securities",* for a reconciliation of cash, cash equivalents, and restricted cash within the consolidated balance sheets.

**<u>Technicolor Contingent Consideration</u>**

As part of the Technicolor Acquisitions, we entered into a revenue-sharing arrangement with Technicolor that created a contingent consideration liability, which is accounted for under *ASC 450 - Contingencies* under the asset acquisition framework when the liability is deemed probable and estimable. Under the revenue-sharing arrangement, Technicolor receives 42.5% of future cash receipts from new licensing efforts from the Madison Arrangement only, subject to certain conditions and hurdles. As of December 31, 2025 and 2024, the contingent consideration liability from the revenue-sharing arrangement was deemed not probable and is therefore not reflected within the consolidated financial statements.

**11.&nbsp;&nbsp;&nbsp;&nbsp;COMMITMENTS**

Minimum future payments for accounts payable and other purchase commitments, excluding commenced long-term operating leases for office space, as of December 31, 2025 were as follows (in thousands):

Refer to Note 10, "*Obligations*," for details of the Company's long-term debt obligations and the revenue-sharing arrangement with Technicolor resulting from the Technicolor Acquisitions. Refer to Note 17, "*Leases*," for maturities of the Company's operating lease liabilities as of December 31, 2025.

***Defined Benefit Plans***

In connection with the Technicolor Acquisitions, we assumed certain defined benefit plans which are accounted for in accordance with *ASC 715 - Compensation - Retirement Benefits*. These plans include a retirement lump sum indemnity plan and jubilee plan, both of which provide benefit payments to employees based upon years of service and compensation levels.

As of December 31, 2025 and 2024, the combined accumulated projected benefit obligation related to these plans totaled $5.5 million and $4.9 million, respectively. Service cost and interest cost for the combined plans totaled less than $0.5 million in each of the years ended December 31, 2025, 2024, and 2023 and the weighted average discount rate and assumed salary increase rate for these plans were 3.5% and 3.3%, respectively. These plans are not required to be funded and were not funded as of December 31, 2025.

Expected future benefit payments under these plans as of December 31, 2025 were as follows (in thousands):

---

**13.&nbsp;&nbsp;&nbsp;&nbsp;COMPENSATION PLANS AND PROGRAMS**

**Compensation Programs**

We use a variety of compensation programs to attract, retain and motivate our employees, and to more closely align employee compensation with company performance. These programs include, but are not limited to, short-term incentive awards tied to performance goals, cash awards to inventors for filed patent applications and patent issuances, and long-term incentives in the form of stock option awards, time-based RSU awards, performance-based RSU awards.

Our long-term incentives typically include annual time-based RSU grants or cash awards with a three-year vesting period, as well as annual performance-based RSU grants or cash awards with a three to five-year performance period; as a result, in any one year, we are typically accounting for at least three active cycles. Additionally, from time to time, executive officers are awarded long term incentives or new hire grants that may include time-based RSUs, performance-based RSUs or options. We issue new shares of our common stock to satisfy our obligations under the share-based components of these programs. However, our Board of Directors has the right to authorize the issuance of treasury shares to satisfy such obligations in the future.

**Equity Incentive Plans**

On June 11, 2025, our shareholders adopted and approved the 2025 Equity Incentive Plan (the "2025 Plan"), under which officers, employees, non-employee directors and consultants can receive share-based awards such as RSUs, restricted stock and stock options as well as other stock or cash awards. Subject to the adjustment provisions contained in the 2025 Plan, as of the effective date of the 2025 Plan, the maximum number of shares for issuance under the 2025 Plan equal to 3.7 million shares of our common stock. Upon adoption of the 2025 Plan by shareholders, the 2017 Equity Incentive Plan (the "2017 Plan") was terminated and no new awards are granted under the 2017 Plan after June 11, 2025.

***RSUs***

We may issue RSUs to officers, employees, non-employee directors and consultants. Any cancellations of unvested RSUs granted under the Equity Plans will increase the number of shares remaining available for grant under the 2025 Plan. Time-based RSUs vest over periods generally ranging from one to three years from the date of the grant. Performance-based RSUs also generally have a vesting period between three and five years. Milestone performance-based RSUs may vest at any time upon achievement of the milestone goal during the performance period, which is seven years for the most recent CEO award.

As of December 31, 2025, we had unrecognized compensation cost related to share-based awards of $41.8 million, at current performance accrual rates. For time-based grants with graded vesting, we expect to amortize the associated unrecognized compensation cost using an accelerated method. For time-based grants that cliff vest, we expect to amortize the associated unrecognized compensation cost as of December 31, 2025, on a straight-line basis generally over the remaining vesting period.

Vesting of performance-based RSU awards is subject to attainment of specific goals established by the Human Capital Committee of the Board of Directors. Depending upon performance achievement against these goals, the number of shares that generally vest can be anywhere from 0 to 2 times the target number of shares.

Information with respect to current RSU activity is summarized as follows (in thousands, except per share amounts):

---

| | | |
|:---|:---|:---|
| | **Number of<br>Unvested<br>RSUs** | **Weighted Average Per Share Grant Date Fair Value** |
| **Balance at December 31, 2024** | 1154 | $79.40 |
| Granted\* | 285 | 213.21 |
| Forfeited | (102) | 127.39 |
| Vested | (482) | 70.17 |
| **Balance at December 31, 2025** | 855 | $123.33 |

---

*\* These numbers include fewer than 0.1 million RSUs credited on unvested RSU awards as dividend equivalents. Dividend equivalents accrue with respect to unvested RSUs when and as cash dividends are paid on the Company's common stock, and vest if and when the underlying RSUs vest. Granted amounts include performance-based RSU awards at their maximum potential payout.*

------

<u>[**Table of Contents**](#ibb62662d68ca424983f0f56e1e5271de_7)</u>

During 2025, 2024 and 2023, we granted approximately 0.3 million, 0.5 million and 0.5 million RSUs under the Equity Plans, respectively, with weighted-average per share grant date fair values of $213.21, $104.08 and $73.80, respectively, assuming target payout for the performance-based awards. The total vest date fair value of the RSUs that vested in 2025, 2024 and 2023 was $105.2 million, $48.1 million and $31.0 million, respectively. The weighted average per share grant date fair value of the awards that vested in 2025, 2024 and 2023 was $70.17, $64.81 and $54.95, respectively.

***Other Equity Grants***

We grant equity awards to non-management Board members and may grant equity awards to certain consultants.

***Stock Options***

The 2017 Plan allowed, and the 2025 Plan allows, for the granting of incentive and non-qualified stock options, as well as other securities. The administrator of the Equity Plans, the Human Capital Committee of the Board of Directors, determines the number of options to be granted, subject to certain limitations set forth in the applicable plan. We grant performance-based stock options to our CEO annually as part of our long-term incentive program. Performance-based options typically have a vesting period between three and five years. Milestone performance-based options may vest at any time upon achievement of the milestone goal during the performance period, which is seven years for the most recent CEO award.

Vesting of performance-based option awards is subject to attainment of specific goals established by the Human Capital Committee of the Board of Directors. Depending upon performance achievement against these goals, the number of performance-based stock options that generally vest can be anywhere from 0 to 2 times the target number of stock options.

Under the terms of the Equity Plans, the exercise price per share of each option, other than in the event of options granted in connection with a merger or other acquisition, cannot be less than 100% of the fair market value of a share of common stock on the date of grant. Options granted under the Equity Plans are generally exercisable for a period of ten years from the date of grant and may vest upon the attainment of specified performance goals.

The fair value for option awards is computed using the Black-Scholes pricing model, whose inputs and assumptions are determined as of the date of grant and which require considerable judgment. Expected volatility was based upon a combination of implied and historic volatilities. The weighted-average grant date fair value per option award granted during the years ended December 31, 2025, 2024 and 2023 was $84.13, $36.00, and $24.41, respectively, based upon the assumptions included in the table below:

---

| | | | |
|:---|:---|:---|:---|
| | **Year Ended December 31,** | **Year Ended December 31,** | **Year Ended December 31,** |
| | **2025** | **2024** | **2023** |
| Expected term (in years) | 6.5 | 6.6 | 7.5 |
| Expected volatility | 39.1% | 31.7% | 32.8% |
| Risk-free interest rate | 4.0% | 4.2% | 3.6% |
| Dividend yield | 1.2% | 1.5% | 1.9% |

---

Information with respect to current year stock option activity is summarized as follows (in thousands, except per share amounts):

---

| | | |
|:---|:---|:---|
| | **Outstanding Options** | **Weighted<br>Average Exercise Price** |
| **Balance at December 31, 2024** | 946 | $77.18 |
| Granted\* | 63 | 206.75 |
| Forfeited |  |  |
| Exercised | (101) | 72.34 |
| **Balance at December 31, 2025** | 908 | $86.77 |

---

*\* Granted amounts include performance-based option awards at their maximum potential payout.*

The weighted average remaining contractual life of our outstanding options was 7.3 years as of December 31, 2025. Options with an indefinite contractual life, which were granted between 1983 and 1986 under a prior stock plan, were assigned an original life in excess of 50 years for purposes of calculating the weighted average remaining contractual life. The majority of these options have an exercise price between $9.00 and $11.63.

The total intrinsic value of our outstanding options as of December 31, 2025 was $210.3 million. Of the 0.9 million outstanding options as of December 31, 2025, 0.4 million were exercisable with a weighted-average exercise price of $63.65. Options exercisable as of December 31, 2025, had total intrinsic value of $111.0 million and a weighted average remaining contractual life of 6.7 years. The total intrinsic value of stock options exercised during the years ended December 31, 2025, 2024 and 2023 was $13.8 million, $0.5 million and $5.4 million, respectively. In 2025, we recorded cash received from the exercise of options of $7.3 million. Upon option exercise, we issued new shares of stock.

As of December 31, 2025, we had unrecognized compensation cost on our unvested stock options of $5.2 million, at current performance accrual rates. As of both December 31, 2025 and 2024, we had approximately 0.9 million options outstanding that had exercise prices less than the fair market value of our stock at the respective balance sheet date. These options would have generated cash proceeds to the Company of $78.8 million and $73.0 million, respectively, if they had been fully exercised on those dates.

**Defined Contribution Plans**

We have a 401(k) plan ("Savings Plan") wherein employees can elect to defer compensation within federal limits. We match a portion of employee contributions. Our contribution expense to our Savings Plan and other defined contributions plans was approximately $1.9 million, $1.7 million and $1.4 million for 2025, 2024 and 2023, respectively.

Under the Deferred Plan, eligible US employees may make tax-deferred contributions that cannot be made under the 401(k) Plan due to Internal Revenue Service limitations. We match 50% of a participant's contributions up to 6% of the participant's applicable compensation. From time to time InterDigital makes discretionary company contributions to the Deferred Plan on behalf of a participant.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)State taxes in Massachusetts & Delaware made up the majority (greater than 50%) of the tax effect in this category

***Income Tax Reform***

The One Big Beautiful Bill Act (the "OBBBA") was signed into law on July 4th, 2025. The OBBBA contains significant tax law changes with various effective dates affecting business taxpayers. Among the tax law changes that will impact the Company relate to the timing and amount of certain tax deductions including FDII, depreciation expense, R&D expenditures and interest expense. The tax law changes did not have an impact on the tax provision in 2025.

***Valuation Allowances and Net Operating Losses***

We establish a valuation allowance for any portion of our deferred tax assets for which management believes it is more likely than not that we will be unable to utilize the assets to offset future taxes. Given the binary nature of our business, at this time we believe it is more likely than not that the majority of our state net operating losses and net operating losses in certain subsidiaries in France, as well as our non-wholly owned subsidiaries in the United States and United Kingdom will not be utilized; therefore we have maintained a near full valuation allowance against our state, French and United Kingdom net operating losses as of December 31, 2025. We also maintain a valuation allowance against certain temporary differences other than the net operating losses in these jurisdictions.

------

<u>[**Table of Contents**](#ibb62662d68ca424983f0f56e1e5271de_7)</u>

At December 31, 2025, we had no U.S net operating loss carryforwards and non-U.S. net operating loss carryforwards amounting to $89.7 million which can be indefinitely carried forward under French statutes. In addition, we had U.S. state net operating loss carryforwards of $1.3 billion, of which $27.7 million can be indefinitely carried forward, while the remaining $1.3 billion will expire in varying amounts from 2026 to 2045. We had $10.1 million of foreign tax credit carried forward that will expire in 2035 and $0.7 million of R&D credit carried forward that will expire in 2045.

The Company recognizes deferred tax balances related to the undistributed earnings of subsidiaries when it expects that it will recover those undistributed earnings in a taxable manner, such as through receipt of dividends or sale of the investments. On December 31, 2025, the Company does not have distributable earnings in foreign subsidiaries that would be subject to deferred taxes.

***Uncertain Income Tax Positions***

As of December 31, 2025, 2024 and 2023, we had $13.5 million, $13.8 million and $14.4 million, respectively, of unrecognized tax benefits that, if recognized, would impact the Company's effective tax rate. The total amount of unrecognized tax benefits could change within the next twelve months for a number of reasons including audit settlements, tax examination activities and the recognition and measurement considerations under this guidance.

During 2025, 2024 and 2023, we reduced the reserve previously established for the amended returns by $0.7 million for the benefit available in the current year had it not been included on the amended returns. In addition, during 2023 we reduced the previously recorded reserve for withholding tax by $1.1 million due to favorable guidance from the taxing authorities in the United States.

The following is a roll forward of our total gross unrecognized tax benefits, which if reversed would impact the effective tax rate, for the fiscal years 2025 through 2023 (in thousands):

Our policy is to recognize interest and/or penalties related to income tax matters in income tax expense.

The Company and its subsidiaries are subject to United States federal income tax, foreign income and withholding taxes and income taxes from multiple state jurisdictions. Our federal income tax returns for 2006 to the present, with the exception of 2011 and 2012, are currently open and will not close until the respective statutes of limitations have expired. The 2014, 2015 and 2018-2020 Federal income tax returns are currently under audit by the IRS. The statutes of limitations generally expire three years following the filing of the return or in some cases three years following the utilization or expiration of net operating loss carry forwards. The statute of limitations applicable to our open federal returns will expire at the end of 2027. The Company is subject to French corporate income tax on certain subsidiaries. The statute of limitations applicable to our open French returns will expire in 2026. Excluding the Korea Competent Authority Proceeding and the Finland Competent Authority Proceeding described in the section below, specific tax treaty procedures remain open for certain jurisdictions for 2014 to the present. Many of our subsidiaries have filed state income tax returns on a separate company basis. To the extent these subsidiaries have unexpired net operating losses, their related state income tax returns remain open. These returns have been open for varying periods, some exceeding ten years. The total amount of state net operating losses is $1.3 billion.

***Foreign Taxes***

We pay foreign source withholding taxes on patent license royalties when applicable. We apply foreign source withholding tax payments against our United States federal income tax obligations to the extent we have foreign source income to support these credits. In 2025, 2024 and 2023, we paid $91.5 million, $23.3 million and $12.0 million in foreign source withholding taxes, respectively, and applied these payments as credits against our United States federal tax obligation.

------

<u>[**Table of Contents**](#ibb62662d68ca424983f0f56e1e5271de_7)</u>

Between 2014 and 2025, we paid approximately $205.2 million in foreign taxes to foreign governments that have tax treaties with the U.S., for which we have claimed foreign tax credits against our U.S. tax obligations, and for which the tax treaty procedures are still open. It is possible that as a result of tax treaty procedures, the U.S. government may reach an agreement with the related foreign governments that will result in a partial refund of foreign taxes paid with a related reduction in our foreign tax credits. Due to foreign currency fluctuations, any such agreement could result in foreign currency gain or loss.

On November 8, 2019, the Company received notification that its request for competent authority pertaining to Article 25 (Mutual Agreement Procedure) of the United States-Republic of Finland Income Tax Convention had been reviewed by the IRS and an agreement has been reached (the "Finland Competent Authority Proceeding"). As a result of this agreement, the Company does not anticipate any tax consequences.

In France, where we have substantial operations, we benefit from research tax credits applicable to French technology companies, including the Crédit Impôt Recherche ("CIR"). While we have historically benefited from the CIR, the French government has recently challenged our eligibility for portions of the CIR that they previously accepted. The Company received notification from the French Tax Authorities that the CIR credit on patent costs has been rejected for tax years 2019 and 2020. The Company has filed petitions in the Lower Court of Paris to litigate this matter. Between 2019 and 2025, the Company has recorded benefits totaling approximately $29 million for CIR credit on patent related costs.

**15.&nbsp;&nbsp;&nbsp;&nbsp;NET INCOME PER SHARE**

Basic Earnings Per Share ("EPS") is calculated by dividing net income available to common shareholders by the weighted-average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution that could occur if options or other securities with features that could result in the issuance of common stock were exercised or converted to common stock or resulting from the unvested outstanding restricted stock units ("RSUs"). The following table reconciles the numerator and the denominator of the basic and diluted net income per share computation (in thousands, except for per share data):

| Diluted | $11.80 | $12.07 | $7.62 |

Shares of common stock issuable upon the exercise or conversion of certain securities have been excluded from our computation of EPS because the strike price or conversion rate, as applicable, of such securities was greater than the average market price of our common stock for the years ended December 31, 2025, 2024 and 2023, as applicable, and, as a result, the effect of such exercise or conversion would have been anti-dilutive. Set forth below are the securities and the weighted average number of shares of common stock underlying such securities that were excluded from our computation of EPS for the periods presented (in thousands):

**Convertible Notes and Warrants**

Refer to Note 10, "*Obligations*," for information about the Company's convertible notes and warrants and related conversion and strike prices. During periods in which the average market price of the Company's common stock is above the applicable conversion price of the Company's convertible notes, or above the strike price of the Company's outstanding warrants, the impact of conversion or exercise, as applicable, would be dilutive and such dilutive effect is reflected in diluted EPS. As a result, in periods where the average market price of the Company's common stock is above the conversion price or strike price, as applicable, under the if-converted method, the Company calculates the number of shares issuable under the terms of the convertible notes and the warrants based on the average market price of the stock during the period, and includes that number in the total diluted shares outstanding for the period.

**16.&nbsp;&nbsp;&nbsp;&nbsp;EQUITY TRANSACTIONS**

**Repurchase of Common Stock** 

In June 2014, our Board of Directors authorized a $300 million share repurchase program (the "Share Repurchase Program"). Subsequently our Board of Directors authorized five $100 million increases to the program, respectively, and an additional $333 million in December 2022 and an additional $235 million in December 2023, bringing the total amount of the Share Repurchase Program to approximately $1.4 billion. The Company may repurchase shares under the Share Repurchase Program through open market purchases, pre-arranged trading plans or privately negotiated purchases.

The table below sets forth the total number of shares repurchased and the dollar value of shares repurchased under the Share Repurchase Program (in thousands). As of December 31, 2025, there was approximately $127.2 million remaining under the Share Repurchase Program authorization.

In 2023, we commenced a modified "Dutch auction" tender offer (the "Tender Offer"), which resulted in the repurchase of 2.7 million shares of our common stock at a price of $72.98 per share, for an aggregate cost of $199.9 million, excluding fees, expenses and excise tax relating to the Tender Offer.

In 2025, we increased the quarterly cash dividend to $0.70 per share beginning with the dividend declared in third quarter 2025 and paid in fourth quarter 2025. Combined with previous increases, we have increased the dividend by 75% since the start of 2024. We currently expect to continue to pay dividends in accordance with our dividend policy; however, continued payment of cash dividends and changes in the Company's dividend policy will depend on the Company's earnings, financial condition, capital resources and capital requirements, alternative uses of capital, restrictions imposed by any existing debt, economic conditions and other factors considered relevant by our Board of Directors.

**17.** &nbsp;&nbsp;&nbsp;&nbsp;**LEASES**

The Company enters into operating leases primarily for real estate to support research and development ("R&D") sites and general office space in North America, with additional locations in Europe, China, and Canada. The Company does not currently have any finance leases. Certain leases include options to extend the lease at our discretion at the end of the lease term, or terminate the lease early subject to certain conditions and penalties. We do not include any renewal options in our lease terms for calculating our lease liabilities, as the renewal options allow us to maintain operational flexibility and we are not reasonably certain we will exercise these options.

At the inception of an arrangement, the Company determines whether the arrangement is or contains a lease based on the specific facts and circumstances present. Operating lease liabilities and their corresponding right-of-use assets are recorded based on the present value of lease payments over the expected lease term. The interest rate implicit in lease contracts is typically not readily determinable, and as such, the Company utilizes its incremental borrowing rate as the discount rate based on information available on the lease commencement date. Our incremental borrowing rate represents the rate we would incur to borrow on a collateralized basis over a similar term for an amount equal to the lease payments in a similar economic environment. The table below includes the balances of operating lease right-of-use assets and operating lease liabilities as of December 31, 2025 and 2024 (in thousands):

**<u>Item 9A.</u> &nbsp;&nbsp;&nbsp;&nbsp;*<u>CONTROLS AND PROCEDURES.</u>***

**Evaluation of Disclosure Controls and Procedures**

The Company's Chief Executive Officer and its Chief Financial Officer, with the assistance of other members of management, have evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of December 31, 2025. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures were effective to ensure that the information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms and to ensure that the information required to be disclosed by us in the reports that we file or submit under the Exchange Act is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

**Management's Annual Report on Internal Control Over Financial Reporting**

Management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. The Company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States of America. Internal control over financial reporting includes those policies and procedures that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the company;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with accounting principles generally accepted in the United States of America, and that receipts and expenditures of the company are being made only in accordance with authorization of management and directors of the company; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the company's assets that could have a material effect on the consolidated financial statements.

Management, including the Chief Executive Officer and Chief Financial Officer, assessed the effectiveness of internal control over financial reporting as of December 31, 2025. Management based this assessment on criteria for effective internal control over financial reporting described in "*Internal Control — Integrated Framework"* issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013). Based on this assessment, management determined that, as of December 31, 2025, the Company maintained effective internal control over financial reporting.

The effectiveness of the Company's internal control over financial reporting as of December 31, 2025 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report that appears under Part II, Item 8, of this Form 10-K.

**Changes in Internal Control over Financial Reporting**

There were no changes in our internal control over financial reporting during fourth quarter 2025 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

<u>&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)The decrease was primarily related to the change in Pennsylvania state tax rate, expired PA net operating losses, and utilization of certain French deferred tax assets. The Chordant entities were dissolved with all DTAs written off during 2025 and well as amending French tax filings adjusting their NOL, all offset by a reclass of valuation allowance.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)The decrease was primarily related to the decrease in Pennsylvania state tax rate and utilization of certain French deferred tax assets. There was a partial release of valuation allowance against deferred tax assets in France due to the Samsung deal in 2024.

**EXHIBIT 19**

**InterDigital, Inc. Insider Trading Policy**

**Introduction**

The Board of Directors (the "**Board**") of InterDigital, Inc. has adopted the following policy (this "**Policy**") regarding trading in securities by its directors, officers, employees and consultants as well as others from time to time who have access to material nonpublic information about the Company. This Policy is designed to promote compliance with certain securities laws and to protect the Company and you from the serious liabilities and penalties that can result from the violation of such securities laws. For purposes of this Policy, all references to the "**Company**" refer to InterDigital, Inc. and all of its subsidiaries.

Federal and state securities laws prohibit buying, selling or making other transfers of securities by persons who are aware of Material Nonpublic Information, as described below. These laws also prohibit persons with such information from disclosing it to others who trade. If you violate the federal insider trading laws, you may have to pay civil penalties of up to three times the profit gained or loss avoided, criminal fines (no matter how small the profit), or serve jail terms.

The Securities and Exchange Commission ("**SEC**"), NASDAQ and state regulators (as well as the New York State Attorney General and the Department of Justice) are very effective at detecting and pursuing insider trading cases. The SEC has successfully prosecuted cases against employees trading through foreign accounts, trading by family members and friends and trading involving only a small number of shares. Therefore, it is important that you understand the breadth of activities that constitute illegal insider trading.

You must <u>carefully read</u> this Policy and follow its directives at all times. Failure to adhere to this Policy or certify as to the matters contained in the attached acknowledgment form may result in immediate disciplinary measures being taken against you, including, where appropriate, termination of employment or service with the Company.

If you have any questions regarding this Policy, you should contact the Legal Department.

**What is "Material Nonpublic Information?"**

**1.&nbsp;&nbsp;&nbsp;&nbsp; MATERIAL INFORMATION**

Material information generally means information a reasonable investor would consider important in making an investment decision to purchase, sell or hold securities. Either positive or negative information may be material. Information that could reasonably be expected to affect market price, whether positively or negatively, is material. Other common examples of material information include: information concerning a potential business acquisition, internal information about revenues, earnings or other aspects of financial performance, important business developments, the acquisition or loss of a major customer, significant litigation developments, an important transaction, significant developments in research and development or relating to intellectual property, major personnel changes, such as changes in senior management or lay-offs, material cyber/security events, or major events involving the securities of the Company, such as stock repurchase programs, option repricings or changes in dividend policies. Please note that this list is merely illustrative and not exhaustive. Investigators will scrutinize a questionable trade after the fact with the benefit of hindsight, so you should always err on the side of deciding that the information is material and not trade. If you have questions regarding specific transactions, please contact the Legal Department.

------

**2.&nbsp;&nbsp;&nbsp;&nbsp; NONPUBLIC INFORMATION**

Nonpublic information is information that is not generally known or available to the public. Information is considered to be available to the public only when:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• it has been released to the public by the Company through appropriate channels (e.g., by means of a press release, SEC filing or a widely disseminated statement from a senior officer); *and*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• enough time has elapsed to permit the market to absorb and evaluate the information.<br>You should generally consider information to be nonpublic until one full trading day has elapsed following public disclosure. For example, if the Company makes a public announcement before the commencement of trading on a Monday (i.e., before the market opens), you will generally be permitted to commence trading in the Company's securities on the Tuesday of that week, because one full trading day would have elapsed (all of Monday). If, however, the Legal Department imposes a longer time period, you will be obligated to refrain from trading until such longer period elapses.

**Trading in the Company's Securities and Securities of Other Public Companies** 

The Company requires compliance with the following rules and procedures with respect to transactions in the Company's securities and the securities of other public companies, as applicable. Securities not only refers to common stock, but also includes, without limitation, preferred stock, notes and other debt instruments, derivative securities, warrants, options, restricted stock units, other stock-based awards, etc. For example, any sale of Company stock that you acquire through the vesting of restricted stock or restricted stock units granted to you by the Company is governed by this Policy. In addition to such sales, references to "**trading**" and "**transactions**" in this Policy *include*, among other things:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• purchases and sales of securities in public markets;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• transfers of securities to third parties including trusts;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• sales of the Company's securities obtained through (i) the exercise of stock options (including same-day sales and cashless exercises), (ii) other stock-based awards granted by the Company or (iii) participation in a Company-sponsored employee stock purchase plan;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• elections to participate in a Company-sponsored employee stock purchase plan and subsequent changes in the amount of your periodic contributions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• (i) any election to enroll in, or increase or decrease the percentage of your periodic contributions to, the Company's Savings and Protection Plan (the "**401(k) Plan**"), if such election results in a change to the dollar amount of your periodic contributions used to purchase Company securities via the Company stock fund, or (ii) any election to make an intra-plan transfer of an existing account balance into or out of the Company stock fund;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• making gifts of the Company's securities (including charitable donations); or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• using the Company's securities to secure a loan.<br>Conversely, references to "**trading**" and "**transactions**" in this Policy *exclude*:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the exercise of Company stock options or the vesting of Company restricted stock, restricted stock units or other stock-based awards if no shares are subsequently sold;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• purchases of the Company's securities through a Company-sponsored employee stock purchase plan or the Company's 401(k) Plan resulting from periodic contributions pursuant to payroll deduction elections;

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• indirect purchases or sales of the Company's securities as a result of ownership in an investment account over which you have no discretion (e.g., mutual funds, ETFs).<br>For example, the mere vesting of restricted stock or restricted stock units granted to you by the Company does not constitute "trading" in the Company's securities and therefore is not governed by this Policy. Similarly, should you elect to have the Company withhold some shares to satisfy tax withholding obligations upon the vesting of your restricted stock or restricted stock units, the exercise of such tax withholding right also does not constitute "trading" in the Company's securities and is not governed by this Policy.

**1.&nbsp;&nbsp;&nbsp;&nbsp; POLICY AGAINST INSIDER TRADING**

Neither you nor anyone who lives in your household, nor any partnership in which you are a general partner, trust of which you are a trustee, estate of which you are an executor or investment fund or similar vehicle over which you exercise investment discretion may trade in the Company's securities when you are aware of Material Nonpublic Information about the Company. Without limiting the generality of the foregoing, Material Nonpublic Information shall be deemed to include knowledge of the planned and impending establishment or modification of any Company share repurchase plan or program. For purposes of this Policy, members of your household also include family members who do not live in your home but whose transactions in Company securities are directed by you or are subject to your influence or control (such as parents or children who consult with you before trading in Company securities). This restriction extends beyond your date of employment or service with the Company; it applies to you so long as you are in possession of Material Nonpublic Information. This Policy also applies to trading in securities of other public companies. You may not trade in securities of any public company at a time when you are in possession of Material Nonpublic Information about such company.

**2.&nbsp;&nbsp;&nbsp;&nbsp; BLACKOUT POLICY**

No director, officer of the Company subject to Section 16 of the Securities Exchange Act of 1934, as amended (the "**Exchange Act**"), and any other person designated and notified by the Legal Department from time to time of their insider status (together with directors and officers, "**Insiders**") nor any member of an Insider's household may trade in the Company's securities during a Blackout Period. Blackout Periods will be determined in the sole discretion of the Legal Department. Insiders will be notified about the timing of Blackout Periods, which will generally commence on the first day of the first month of each fiscal quarter and end one (1) full trading day after the release of revenue guidance for such fiscal quarter. In addition, no director or officer of the Company subject to Section 16 of the Exchange Act may trade in the Company's securities during the four (4) trading days following the public announcement of a Company share repurchase plan or program or an increase of an existing Company share repurchase plan or program. To avoid even the appearance of impropriety, the Blackout Periods apply whether or not an Insider is, or a member of an Insider's household is, aware of Material Nonpublic Information about the Company.

------

**3.&nbsp;&nbsp;&nbsp;&nbsp; SPECIAL BLACKOUT PERIODS**

From time to time, the Company may also temporarily prohibit trading in the Company's securities due to specific developments or circumstances involving Material Nonpublic Information. In such event (a "**Special Blackout Period**"), the Legal Department will notify you that neither you nor any member of your household may engage in any transactions involving the Company's securities until you receive a subsequent notification that such restriction has been lifted. During a Special Blackout Period, you should not trade in the Company's securities, and you should not inform anyone within or outside the Company about the existence of the Special Blackout Period or the fact that you are prohibited from trading. There may be quarters during which the existence of Material Nonpublic Information means that you are restricted from trading and the window to trade does not open.

**4.&nbsp;&nbsp;&nbsp;&nbsp; PRECLEARANCE POLICY**

Insiders must request preclearance from the Legal Department to trade in the Company's securities by such Insider or by any member of such Insider's household. Executive Officers of the Company must request preclearance from the Chief Executive Officer or Chief Financial Officer, in addition to the Legal Department. Any such preclearance may be approved or denied, in the sole discretion of the Legal Department and/or the Chief Executive Officer or Chief Financial Officer and for any reason, irrespective of whether there exists any Material Nonpublic Information. If clearance to trade is approved, transactions must be executed within five (5) business days after the approval is obtained, but it may not be executed under any circumstances if the Insider is aware of Material Nonpublic Information concerning the Company or if preclearance is revoked by the Legal Department for any reason. If the transaction is not completed within the period described above, clearance to trade must be approved again before it may be executed. If clearance to trade is not approved under the preclearance policy, the Insider should refrain from initiating any transaction in the Company's securities, and the Insider should not inform anyone within or outside the Company of the restriction.

**5.&nbsp;&nbsp;&nbsp;&nbsp; REGULATION BTR BLACKOUTS**

Insiders may also be subject to trading blackouts pursuant to Regulation Blackout Trading Restriction, or Regulation BTR, under U.S. federal securities laws. In general, Regulation BTR prohibits any director or executive officer from engaging in certain transactions involving Company securities during periods when 401(k) plan participants are prevented from purchasing, selling or otherwise acquiring or transferring an interest in certain securities held in individual account plans. Any profits realized from a transaction that violates Regulation BTR are recoverable by the Company, regardless of the intentions of the director or officer effecting the transaction. In addition, individuals who engage in such transactions are subject to sanction by the SEC as well as potential criminal liability.

The Company will notify directors and officers if they are subject to a blackout trading restriction under Regulation BTR. Failure to comply with an applicable trading blackout in accordance with Regulation BTR is a violation of law and this Policy.

**6.&nbsp;&nbsp;&nbsp;&nbsp; PROHIBITION AGAINST TIPPING**

You may not disclose Material Nonpublic Information about the Company or any other public company to another person, or suggest to another person that he or she trade, or otherwise assist another person with such a trade while you are aware of Material Nonpublic Information about the Company or another public company, as applicable. This practice, known as "tipping," also violates the securities laws and can result in the same civil and criminal penalties that apply if you were to engage in insider trading directly, even if you do not receive any money or derive any benefit from trades made by the person(s) to whom you passed Material Nonpublic Information. Accordingly, in addition to your general obligations to maintain the confidentiality of information obtained through your employment (see the discussion below captioned "Confidentiality and Communications") and to refrain from trading while in the possession of such information, you must take the utmost care not to discuss Material Nonpublic Information about the Company and its securities, as well as information about other public companies, with family members, friends or other persons. This prohibition does not restrict legitimate business communications on a "need to know" basis, where you have a basis to expect that the other person will not trade while in possession of the information.

**Responding to outside inquiries for information**

In the event you receive an inquiry from someone outside of the Company, such as a stock analyst, for information, you should refer the inquiry to the Legal Department or the Company's Investor Relations Department. The Company is required under Regulation FD (Fair Disclosure) of the U.S. federal securities laws to avoid the selective disclosure of Material Nonpublic Information. In general, the regulation provides that when a public company discloses Material Nonpublic Information, it must provide broad, non-exclusionary access to the information. Violations of this regulation can subject the company to SEC enforcement actions, which may result in injunctions and severe monetary penalties. The Company has established procedures for releasing material information in a manner that is designed to achieve broad public dissemination of the information immediately upon its release in compliance with applicable law.

**7.&nbsp;&nbsp;&nbsp;&nbsp; PROHIBITION AGAINST SPECULATIVE TRANSACTIONS, HEDGING, SHORT SALES, PLEDGING AND TRADING ON MARGIN**

It is against Company policy for you to engage in speculative transactions in Company securities. As such, it is against Company policy for you to trade in puts or calls in the Company's securities or to sell Company securities short. You are also prohibited from day trading in the Company's securities. For purposes of this Policy, "**day trading**" means any market sale followed by a market purchase, or vice versa, of Company securities within fourteen (14) days (excluding an exercise of Company-granted stock options and purchases and sales under the 401(k) Plan).

Because certain forms of hedging transactions, such as zero cost collars and forward sale contracts, in certain instances involve the establishment of a short position (or an equivalent position) in Company securities and limit or eliminate the ability to profit from an increase in, or limit or eliminate exposure to a decrease in, the value of Company securities, you are prohibited from engaging in any hedging transactions involving Company securities.

Additionally, because securities held on margin (or margined) or pledged as collateral may be sold without your consent if you fail to meet a margin call or if you default on a loan, a margin or foreclosure sale may result in unlawful insider trading. Because of this danger, you must consult with the Company's Chief Legal Officer with regard to including Company securities in a margin account or pledging Company securities as collateral for a loan.

------

**Prearranged Trading Plans**

The SEC has adopted Rule 10b5-1(c) under the Exchange Act, which provides for an affirmative defense against insider trading liability if trades occur pursuant to a prearranged trading plan that meets specified conditions. The Company authorizes the use of such prearranged trading plans by Insiders and others under certain conditions. Only transactions made by an Insider pursuant to a trading plan that (i) meets the requirements set forth below and (ii) has been approved by the Company's Legal Department (each such trading plan that meets the foregoing requirements, an "**Approved Plan**") are eligible for exemption from the policies set forth above regarding trading in the Company's securities. Insiders should recognize, however, that transactions made pursuant to an Approved Plan do not eliminate the risk that an Insider may be sued by a shareholder or have an action brought against the Insider by the SEC or a state authority under insider trading laws. An Approved Plan will merely provide an Insider with an affirmative defense to such claims and an exemption from the policies set forth above relating to trading in the Company's securities. Moreover, while Approved Plans are subject to review and approval by the Company, the Insider or individual using the Approved Plan is ultimately responsible for compliance with Rule 10b5-1 and ensuring that the Approved Plan complies with applicable securities laws including Rule 10b-5.

To establish an Approved Plan, an Insider must, at a time when the Insider does not possess Material Nonpublic Information and that is not a Blackout Period or Special Blackout Period, and when acting in good faith and not as a part of a scheme to evade the federal insider trading laws:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• enter into a binding contract to purchase or sell securities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• instruct another person to purchase or sell securities for the Insider's account; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• adopt a written plan for trading securities.

Furthermore, such contract, instruction or plan must:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• specify the amount of securities to be purchased or sold and the price at which and the date on which the securities are to be purchased or sold or include a written formula or algorithm for determining the amount of securities to be purchased or sold and the price at which and the date on which the securities are to be purchased or sold; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• not permit any subsequent influence by the Insider over how, when or whether to effect purchases or sales and require that any third person who does exercise such influence not be aware of any Material Nonpublic Information when doing so.<br>In addition, please be advised that many brokers executing Approved Plans require that a certain period of time elapse between entry into or modification of the plan and the first transaction(s) under the plan. Additionally, while transactions effected under an Approved Plan are exempt from the policies set forth above regarding trading in the Company's securities, such transactions must nonetheless be made in accordance with applicable securities laws, including Rule 144 and Section 16 of the Exchange Act, as applicable.<br>The Company may publicly disclose information regarding trading plans that you may enter. Approved Plans may be modified or suspended only with the approval of the Legal Department. Under no circumstances may an Insider modify or suspend an Approved Plan at a time when the Insider is aware of Material Nonpublic Information.<br>The Company shall have the right to require cessation of transactions effected pursuant to an Approved Plan at certain times.

------

**8. POST-TERMINATION TRANSACTIONS**

This Policy continues to apply to transactions in securities of the Company even after termination of service to the Company. If an individual is in possession of Material Nonpublic Information when his or her service terminates, that individual may not trade in securities of the Company until that information has become public or is no longer material. Additionally, the pre-clearance procedures specified under the heading "Preclearance Policy" above will continue to apply for Insiders for 90 days after the time of the termination of service.

**Confidentiality and Communications**<br>Serious problems for the Company could result from any unauthorized disclosure of internal information about the Company or confidential information about our customers, prospective customers, partners or vendors, or entities similarly situated, whether or not for the purpose of facilitating improper trading in the Company's securities. Consequently, you are hereby reminded of your obligations relating to confidentiality and communications under the Company's Code of Ethics.

**Consequence of Violation of this Policy** <br>The Company considers strict compliance with this Policy to be a matter of the utmost importance. Violation of this Policy could cause legal liability and other adverse consequences for you and the Company. Violations of this Policy will be considered by the Company as grounds for immediate dismissal from the Company or other disciplinary action. Violations of this Policy might also expose you to severe criminal penalties as well as civil liability under the federal and state securities laws, as discussed above.

**Warning Regarding Possible Inability to Sell** <br>Trading in the Company's securities will be prohibited from time to time pursuant to Blackout Periods, Special Blackout Periods, because of the existence of Material Nonpublic Information and/or for any other reason, in the sole discretion of the Legal Department and/or the Chief Executive Officer or Chief Financial Officer. Anyone purchasing the Company's securities must consider the inherent risk that the sale of securities could be prohibited at a time when you desire to sell such securities. The next opportunity to sell might not occur until after an extended period, during which the market price of the securities might decline. As discussed above, you may continue to be subject to the restrictions of this Policy even following your separation from the Company.

**Resolving Doubts** 

<br>If you have any doubt as to your responsibilities under this Policy, seek clarification and guidance from the Legal Department before you act. Do not try to resolve uncertainties on your own.

**Effective Date** 

<br>This Policy shall be effective immediately. This Policy is subject to amendment by the Company's Chief Legal Officer at any time, provided that the Board will be apprised of any material changes at the next regular Board meeting following any such change.<br>Amended as of September 2025
