Wireline revenues more than doubled, driven by rising testing needs in AI data centers and connectivity.
Keysight Technologies, Inc. (KEYS - Free Report) is benefiting from strong momentum in its Communications Solutions Group (CSG). In the third quarter, CSG generated $1.35 billion in third-quarter fiscal 2026 revenues, up 43% year over year, accounting for roughly 73% of total company revenue. The segment also delivered a 70.8% gross margin and 34.0% operating margin.
The Commercial Communications business was the biggest contributor to CSG's growth. Revenues reached $1.006 billion, up 56% year over year, marking its first billion-dollar quarter. Wireline revenues more than doubled year over year and exceeded Wireless revenues for the first time. The trend reflects increasing testing requirements in high-speed connectivity and AI data-center infrastructure.
In the third quarter of fiscal 2026, wireless orders grew again as customers increased spending on next-generation connectivity and the supply chain supporting AI infrastructure. The Third Generation Partnership Project (3GPP) timeline now targets the first 6G standard for March 2029, and management said customers are moving from exploratory research into funded development programs. This can lead to strong growth prospects in the long run.
Aerospace, Defense and Government also contributed to CSG's performance. Revenues in this business increased 14% year over year to $339 million. Orders grew double-digit. Demand was driven by advanced radar architectures, autonomous platforms, satellite systems and resilient positioning, navigation and timing solutions. Backed by favorable trends, KEYS expects fourth-quarter fiscal 2026 revenues of $1.93-$1.95 billion, implying approximately 37% year-over-year growth at the midpoint.
