In licensing, our wireless communications IPs continue to be in strong demand, underpinned by three more Wi-Fi & Bluetooth combo deals, including a customer for our new Wi-Fi 7 IP for Access Points. In royalties, we reported our second highest CEVA-powered device shipments in a quarter, totaling half a billion units. These results reflect robust restocking demand for consumer devices and illustrative of the strength of our customer base."
