KLA reports tool lifespan expanded to 24 years as legacy process nodes see extended use
Saturday, March 14, 2026 at 09:26 AM
KLA has observed a significant increase in the operational lifespan of its semiconductor manufacturing tools, rising from a median of 4 years in 2000 to 24 years today. This extension, driven by the longer shelf life of various process nodes, significantly exceeds the typical 5-7 year customer depreciation cycle. Consequently, older equipment generations, such as those from 1995, still generate substantial annual service revenue. KLA has subsequently raised its service business compound annual growth rate (CAGR) forecast to 13-15%.
Context
As of March 2026, KLA Corporation has reported a significant extension in the operational lifespan of its semiconductor tools, with the median time to retirement reaching 24 years. This represents a sixfold increase from the 4-year lifespan observed in 2000 and significantly exceeds the standard customer depreciation cycle of 5-7 years. This shift is driven by the extended utility of legacy process nodes, which allows older equipment to remain productive for decades. Notably, systems manufactured in 1995 continue to generate $100 million in annual service revenue thirty years later.
This trend has substantial financial implications, as KLA recently raised its service business revenue CAGR target to 13-15%. With an installed base of over 50,000 tools, the company’s service segment provides high-margin, recurring revenue that effectively funds its capital return programs. Following these developments, KLA announced a new $7 billion share repurchase authorization and a 21% increase to its quarterly dividend, marking its 17th consecutive annual dividend hike.
