Keysight (KEYS) Q3 2025 earnings review
AI Drives Strong Beat and Raise, but New Tariffs Create Margin Headwinds
Keysight delivered strong Q3 results, beating top and bottom-line guidance as revenue growth accelerated to 11% YoY. The performance was driven by sustained, robust demand for AI-related wireline solutions and a significant recovery in the industrial segment. For the second consecutive quarter, the company raised its full-year FY25 guidance, now expecting ~7% revenue and ~13% EPS growth. However, this optimism is tempered by new tariffs announced in August, which are expected to double the company's annual exposure to ~$150-175 million. Management plans to fully mitigate this impact by mid-FY26, but it will pressure margins in the interim.
🐂 Bull Case
The wireline business, a key beneficiary of the AI infrastructure build-out, continues to show strong double-digit growth, driving the Commercial Communications end market up 13% YoY. Management sees this as a durable, multi-year trend.
The Electronic Industrial Solutions Group (EISG) returned to strong growth, with revenue up 11% YoY. This recovery, driven by semiconductor and general electronics, provides a second major growth engine for the company.
Management raised full-year guidance for the second consecutive quarter, signaling strong execution and a healthy pipeline of opportunities despite macroeconomic uncertainty and new tariff pressures.
🐻 Bear Case
Newly announced tariffs will increase the company's annual exposure to an estimated $150-$175 million. While a mitigation plan is in place, it will take until mid-FY26 to be fully effective, creating a margin drag for the next few quarters.
Q4 revenue guidance implies YoY growth of ~7%, a notable deceleration from Q3's 11% pace. While partly due to the timing of a large deal, it suggests a moderation in growth heading into FY26.
Management commentary continues to highlight challenges in the automotive end market, which remains a drag on the otherwise recovering industrial segment.
⚖️ Verdict: 🟢
Bullish. The operational momentum from the durable AI trend, combined with the confirmed recovery in the industrial segment, is powerful. While the doubling of tariff headwinds is a clear negative, management has a credible mitigation plan and has still raised full-year guidance. The strong execution and positive demand signals outweigh the near-term margin pressure.
Key Themes
Tariff Headwinds Intensify, Doubling Exposure
The primary concern is the impact of new tariffs announced on August 1. Management estimates this will add ~$75 million in annual costs, raising the total gross exposure to a range of $150-$175 million. While mitigation strategies are underway, they will not be fully realized until the first half of FY26. This creates a direct contradiction to the positive margin narrative, as these costs will pressure gross and operating margins in Q4 and early FY26 before mitigation efforts like pricing and supply chain shifts catch up.
AI Infrastructure Remains the Primary Growth Engine
Keysight's wireline business is capitalizing on the massive investment in AI data centers. This drove a 13% increase in Commercial Communications revenue, the fastest-growing end market. The company is enabling next-generation technologies, delivering the industry's first protocol layer solution for 1.6 terabit performance and partnering with AMD on PCIe Gen 6 validation. Management views this as a long-term secular tailwind that extends beyond hardware to system-level emulation of complex AI workloads.
Industrial Segment (EISG) Returns to Strong Growth
After multiple quarters of decline, the Electronic Industrial Solutions Group (EISG) posted strong 11% YoY revenue growth, matching the pace of the communications segment. This recovery was broad-based, with robust demand for wafer test solutions driven by AI-related semiconductor investment, and order growth in general electronics and digital health. The return of this segment to growth provides a significant boost to the company's overall profile.
Resilient Aerospace & Defense Demand
The Aerospace, Defense & Government (AD&G) segment continues to be a source of strength, with revenue growing 8% YoY. Management noted that elevated global defense spending and modernization priorities are driving robust demand, particularly in the U.S. and Europe. Key wins in radar and electromagnetic spectrum operations applications underscore Keysight's strong position in this market.
Automotive Market Remains Challenged
While the broader industrial segment is recovering, management commentary continues to flag the automotive sector as a point of weakness. While demand has stabilized, the persistent challenges and cautious spending from OEMs, particularly in EV-related areas, are preventing the EISG segment from reaching its full potential.
Software and Services Provide Stability
The strategic shift towards software and services continues to add resilience to the business model. This category accounted for approximately 36% of total revenue in the quarter, with annual recurring revenue (ARR) at 28%. Strong renewal rates and growing demand for simulation and emulation software, particularly in RF-EDA for AI and defense applications, underscore the success of this strategy.
Other KPIs
Stable. The company continues to demonstrate strong cash generation, with year-to-date free cash flow reaching $1.1 billion. This financial strength supports ongoing R&D investment, strategic acquisitions like Spirent, and shareholder returns, with $50 million in shares repurchased during the quarter.
Improving. The Communications Solutions Group (CSG) maintained a stable and healthy 26% operating margin. More notably, the Electronic Industrial Solutions Group (EISG) saw its operating margin expand to 22% from 20% a year ago, demonstrating strong operating leverage as revenue recovers in that segment.
Slightly negative, but driven by timing. Orders of $1.340 billion came in just below revenues of $1.352 billion. However, management explained this was due to a large system integration deal receiving customer acceptance on the last day of the quarter, pulling revenue recognition into Q3 that would have otherwise fallen in Q4. This suggests underlying demand remains healthy.
Guidance
Decelerating. The midpoint of $1.380 billion implies YoY growth of 7.2%, a deceleration from the 11.1% growth reported in Q3. Management attributes this to the pull-forward of a large deal into Q3, which muted the typical sequential growth profile for Q4.
Accelerating slightly. The midpoint of $1.82 implies 10.3% YoY growth, a slight acceleration from Q3's 9.6%. This is primarily due to a more favorable year-over-year tax rate comparison in the fourth quarter.
Accelerating. The updated full-year outlook represents the second consecutive quarterly raise. The revenue growth target was increased from the 'midpoint of 5-7%' last quarter, and the EPS growth target was raised from 'slightly above 10%'. This demonstrates management's growing confidence in the business trajectory for the full year.
Key Questions
Tariff Mitigation Details
Regarding the new $75M annual tariff impact, can you provide more detail on the mitigation plan? What is the expected split between pricing actions versus supply chain shifts, and should we model a sequential step-down in gross margin in Q4 and Q1'26 before it begins to recover?
EISG Recovery Drivers
The 11% growth in EISG is a significant positive. Can you provide more color on the drivers within the segment? How much of the strength came from semiconductors versus general electronics, and is the recovery in general electronics broad-based or concentrated in specific areas like AI-related high-speed PCBs?
Underlying Growth Rate
You guided Q4 revenue growth to decelerate to ~7% from 11% in Q3, citing a deal pull-in. Excluding that specific timing impact, what does the underlying sequential and year-over-year growth profile for the business look like heading into fiscal 2026?
Sustainability of AI Demand
The wireline business is clearly benefiting from strong AI investment. How sustainable is this double-digit growth? Are you seeing signs of demand broadening from the initial group of hyperscalers to second-tier cloud providers or large enterprise customers?
