• Operating results may fluctuate significantly due to factors like timing of revenue recognition, making future results difficult to predict.
• The stock repurchase program may not result in a positive return of capital if the stock price declines.
• Shareholders may not receive the expected level of dividends, and any decrease or suspension could cause the stock price to decline.
• Securities analyst coverage or lack thereof may negatively impact the common stock's market price.
• Indebtedness could adversely affect business, financial condition, and ability to meet payment obligations.
• Convertible note hedge and warrant transactions may affect the value of notes and the market price of common stock, potentially leading to substantial dilution.
• Counterparty risk with respect to convertible note hedge transactions if option counterparties default.
• Provisions of the 2027 Notes could discourage an acquisition of the company by a third party.
• Anti-takeover provisions could delay and discourage takeover attempts.
• Inability to attract and retain qualified employees due to intense competition for specialized talent.
• Macroeconomic conditions (inflation, high interest rates, trade tensions, global conflicts) may harm the business by increasing costs without corresponding revenue increases.
• Strategic decisions about the patent portfolio (e.g., divestitures, filing strategies) involve risks and may not realize anticipated benefits.
• Business is subject to evolving domestic and international laws, rules, and policies regarding data protection, leading to compliance costs and potential regulatory actions.
• Patent exhaustion or implied license issues from commercialization, licensing, or M&A activities could adversely affect patent licensing programs.
• Use of open source software could expose intellectual property to adverse licensing conditions or require re-engineering.
• Exposure to additional tax liabilities due to complex and changing tax laws, ongoing audits, and potential changes in tax rates or deductions (e.g., FDII, CIR).

Future Outlook

InterDigital anticipates continued growth in the smartphone market beyond 2025, driven by 5G adoption and new technologies. Global cellular IoT device shipments are projected to increase from approximately 550 million in 2025 to 800 million by 2029, with connected passenger vehicles also expected to grow significantly.
