KLA Service Revenue Hits $775M, But Timing and Valuation Risks Persist

What happened

KLA's service business generated $775 million in the March quarter, underscoring the recurring revenue strength from AI-driven demand and longer tool lifecycles. However, the DeepValue report maintains a WAIT rating, highlighting that near-term optics supply constraints and export control uncertainties continue to limit revenue conversion. While services now represent about 22% of revenue and provide a cash flow buffer, the stock trades at 42x P/E with no margin of safety. The key catalyst remains the ability to demonstrate a clear 2H CY2026 shipment ramp, with formal evidence expected by the May 2026 earnings cycle.

Implication

KLA's service business provides a durable annuity that should support cash flows through cyclical dips, but the current valuation leaves little room for error. Investors should wait for either a pullback to the attractive entry zone ($1,250) or hard evidence by May 2026 that optics bottlenecks and fab readiness are no longer gating revenue conversion. The service revenue growth is a positive long-term anchor, but near-term execution frictions and high multiple compress expected returns.

Thesis delta

The March-quarter service revenue beat reinforces the recurring revenue story and suggests the services growth anchor is strengthening, but this does not change the core thesis that near-term upside is limited by supply and policy constraints at a crowded valuation. The positive service data slightly increases the probability of the bull case but does not shift the WAIT rating until supply chain evidence materializes.
