Keysight Q3: Record AI-Driven Results, Supply Constraints Cap Near-Term

Record Q3 Results and Raised Guidance Keysight reported record revenue of $1.85 billion, up 36%, EPS of $3.07, and orders up 56% to $2.09 billion, driven by AI infrastructure demand. Management raised guidance, and analysts lifted price targets to $400–$440.
This is the core new financial performance that drove the stock in Q3.
New Partnerships and 6G/Lab Automation Initiatives New initiatives with Intel Foundry, Lockheed Martin, 6G, and lab automation support future growth. However, 6G's expected inflection is not until early 2028, so it remains a longer-term bet.
These new business developments underpin future revenue potential and were highlighted this period.
Supply Chain Constraints Cap Near-Term Revenue Supply chain constraints remain the key counterweight, capping near-term revenue even as demand exceeds supply. Some revenue is pushed beyond the normal six-month order-to-revenue window, so execution depends on capacity expansion and supply easing.
This is the main risk that limits how much of the strong demand converts to revenue in the near term.
