Total revenue for the third quarter of 2022 was $33.7 million, a 3% increase compared to $32.8 million reported for the third quarter of 2021. Third quarter 2022 licensing, non-recurring engineering (NRE) and related revenue was $22.3 million compared to $21.6 million reported for the same quarter a year ago. Royalty revenue for the third quarter of 2022 was $11.4 million compared to $11.2 million reported for the third quarter of 2021.
During the quarter, eighteen IP license and NRE agreements were concluded with customers targeting a wide variety of applications including ADAS, Wi-Fi access points and endpoints, wireless audio devices and satellite communications. Five of the agreements were with first-time customers. Geographically, nine of the deals signed were in China, seven were in the U.S., and two were in Japan.
Gideon Wertheizer, CEO of CEVA, stated: "Despite the challenging demand environment, we delivered year-over-year revenue growth in both licensing and royalties in the third quarter. Our royalties from 5G RAN are benefiting from share gains in China and the consistent rollout of new base stations in the U.S., helping to grow our base station & IoT royalties 16% quarter-over-quarter to $8.2 million. Moreover, we expect 5G RAN royalties to grow further next year as 5G base station rollouts in India begin. Of note, our presence in the wearable space expanded during the quarter as a major OEM launched a new wearable device using our cellular technology."
Wertheizer concluded: "CEVA is well-positioned to continue its track record of consistently delivering innovation, further cementing its industry leadership position. I have decided now is the right time for me to retire and to hand the reins to our next leader. Amir Panush brings strategic vision, management skills and customer expertise that will help drive CEVA's continued growth in years to come. I am very pleased the board has chosen Amir to lead the company in the new year and look forward to supporting him as a board member and advisor."
