Keysight Technologies Inc. Common Stock (KEYS) : juste valeur

Thèse ACCE

Keysight designs and manufactures electronic measurement instruments and software used in semiconductor design, manufacturing, and network testing. The company sells oscilloscopes, spectrum analyzers, and network protocol analyzers alongside software platforms that simulate and validate chip designs before fabrication. The structural advantage lies in high switching costs: once an engineer standardizes on Keysight's tools within a design flow, replacing them means retraining teams and revalidating entire workflows. This stickiness compounds as customers move up the value chain into software and services, where margins expand and churn declines. The near-term driver is semiconductor capital intensity. Advanced chip nodes require more complex validation; a 3-nanometer design involves orders of magnitude more test scenarios than a 28-nanometer node. Keysight's software revenue, which carries higher margins and recurring revenue characteristics, grew 36% last year and now represents roughly 40% of total revenue. The valuation disconnect is worth examining. At a forward PE of 27.5x against 36.5% revenue growth and 25.7% operating margins, the stock prices in deceleration. Yet the company has returned 20.9% ROE while reinvesting heavily in R&D, suggesting the market may be underweighting the durability of its installed base and the margin expansion potential as software penetration deepens.
