Keysight Q3 Revenue Jumps on AI Demand

Keysight Technologies reported strong Q3 2025 results, with revenue up 11% year-over-year to $1.35 billion and non-GAAP EPS of $1.72, both exceeding guidance. This outperformance was significantly driven by double-digit growth and record bookings in its wireline business, fueled by robust AI demand and accelerated technology refresh cycles. Despite absorbing $75 million annually from new tariffs, the company is implementing effective mitigation strategies, including supply chain diversification, aiming for dollar-neutrality by fiscal 2026. Management raised full-year guidance, now projecting 7% revenue growth and 13% non-GAAP EPS growth, reflecting confidence in its AI-centric market position and operational resilience.

Analysis

Keysight Technologies delivered a strong third quarter for fiscal 2025, with revenue climbing 11% year-over-year to $1.35 billion and non-GAAP EPS reaching $1.72, both surpassing the upper end of its guidance. This outperformance is primarily fueled by its wireline business, which is experiencing strong double-digit growth and record-high bookings, in stark contrast to a normalized wireless segment. The surge is directly attributed to robust demand from the AI ecosystem, where Keysight is capitalizing on accelerated technology refresh cycles with new product launches like industry-first 1.6 terabit network test solutions. While the company faces a significant headwind from tariffs, now totaling $150 million to $175 million annually, management has articulated a clear mitigation strategy involving supply chain diversification and price actions, projecting a dollar-neutral impact within fiscal 2026. Reflecting this operational resilience and demand strength, the company raised its full-year outlook to 7% revenue growth and 13% non-GAAP EPS growth, supported by a durable pipeline in commercial communications that management sees extending well into 2028 and beyond.

Key Decisions for Investors

• The Q3 results validate Keysight's strategic positioning as a key enabler of the AI infrastructure buildout, and investors should view the wireline segment's performance as a powerful secular growth driver.
• Monitor the execution of the company's tariff mitigation strategy, specifically its progress towards achieving dollar-neutrality by fiscal 2026, as any deviation could impact the targeted 40% incremental margins.
• Given the raised full-year guidance and management's commentary on accelerating, multi-year technology refresh cycles, the current results support a bullish thesis for initiating or adding to positions, as the underlying business drivers appear sustainable.
