Kla brought in $9.94B from its six regions in fiscal 2026, the year ended June 30, 2026. That is less than the $13.08B it reports by product and service, so these regions do not cover all of its revenue. China was the largest at $4.05B (40.7%), ahead of Korea at $1.83B (18.5%) and North America at $1.76B (17.7%). The other three regions brought in $2.30B combined.
Compared with fiscal 2025, Rest Of Asia grew fastest, up 69.6% to $654.40M, while Japan fell the most, down 19.2% to $915.11M. Some of that change comes from Kla regrouping its regions.
Kla stopped reporting Taiwan as a separate region after fiscal 2025, when it brought in $3.21B.
Wafer Inspection was Kla’s largest product and service line in fiscal 2026, bringing in $6.63B of $13.08B (51%).

Kla brought in $13.08B from its five product and service lines in fiscal 2026, the year ended June 30, 2026. Kla regrouped these lines after fiscal 2025, so the total does not compare directly with that year's $12.16B. Wafer Inspection was the largest at $6.63B (50.7%), ahead of Service at $3.13B (23.9%) and Patterning at $2.71B (20.7%). The other two lines brought in $613.44M combined.
Compared with fiscal 2025, Pcb & Component Inspection grew fastest, up 29.3% to $460.32M. Every line above 2% of revenue grew.
