InterDigital combines a 71% EBITDA-margin SEP licensing model, record $625.7 million ARR, and streaming upside with meaningful FRAND litigation and customer-concentration risks.
Overview
InterDigital is a research-first intellectual-property company that designs and patents cellular wireless, video compression, and AI technologies, then licenses standard-essential portfolios to device manufacturers and digital-service providers. Its revenue model combines approximately 90% fixed-price recurring royalties with lumpier catch-up payments for historical unlicensed shipments. The company’s moat rests on more than 40,000 IP assets, contributions to 5G, 6G, and VVC standards, two 3GPP chair positions, and licenses covering approximately 85% of global smartphone shipments. **The core financial trajectory is stronger than headline revenue volatility suggests:** Q2 2026 ARR reached a record $625.7 million, up 13% year over year, even as total revenue fell 13% to $260.2 million because catch-up revenue declined to $103.7 million from $162.3 million. Non-GAAP EPS of $4.62 beat the $1.48 consensus by 212%, and Adjusted EBITDA was $184.1 million at a 71% margin. Management raised 2026 revenue guidance to $775 million–$845 million and non-GAAP EPS guidance to $10.85–$12.81. The stock closed at $303.33 after rising 16.16% on July 30 and later traded near $334.65–$345.54. Catalysts include Amazon arbitration, Disney enforcement, remaining smartphone renewals, streaming growth, and buybacks; the principal valuation risks are FRAND royalty compression, customer concentration, and dilution.
