The AI-driven growth in semiconductors is remarkable, with the total semiconductor market anticipated to exceed $1 trillion annually by the end of 2026. While e-commerce remains a relatively small portion of our revenue to date, our growing momentum and robust pipeline in this market gives us confidence that it could be much more significant in the future. We continue to make steady progress towards reaching our long-term goal of $500 million in annual licensing revenue. A key driver of this progress is our ability to add new, high-value customers such as AMD and Microsoft, agreements that provide sustainable recurring revenue streams.
In the first quarter, non-pay TV recurring revenue grew 28% year-over-year, reflecting further expansion into growth markets.

We continue to invest strategically in both organic R&D and targeted tuck-in acquisitions to ensure we maintain and enhance the value of our portfolio over time.
