VizualStocks APIOperating KPI and segment definitions available for KLA (KLAC) through the VizualStocks API.
KLA revenue shipped to customers in China across semiconductor process-control, specialty-process, PCB/component-inspection and service offerings. Geography is assigned by customer ship-to location, not by KLA's manufacturing site or customer headquarters.
chinaRevenueThe foreign-currency and other corporate adjustments that reconcile revenue from KLA's three reportable segments to consolidated revenue. This is not revenue from a separate corporate business and can be positive or negative.
corporateAndUnallocatedRevenueKLA revenue shipped to customers in Europe and Israel across its equipment and service businesses. Geography is assigned by customer ship-to location, and KLA combines these destinations into one reporting region.
europeAndIsraelRevenueKLA revenue shipped to customers in Japan across its semiconductor equipment and service businesses. Geography is assigned by customer ship-to location rather than customer headquarters.
japanRevenueKLA revenue shipped to customers in South Korea across its semiconductor equipment and service businesses. Geography is assigned by customer ship-to location rather than customer headquarters.
koreaRevenueKLA revenue shipped to customers in North America across its semiconductor equipment and service businesses. Geography is assigned by customer ship-to location rather than the location where KLA built the product.
northAmericaRevenueGross profit not allocated to KLA's Semiconductor Process Control, Specialty Semiconductor Process, or PCB and Component Inspection segments. It reconciles the three segment amounts to consolidated gross profit and reflects corporate or currency-related adjustments, not a fourth business.
otherGrossProfitRevenue from KLA's refurbished systems, remanufactured legacy tools, and enhancements or upgrades for previous-generation products. These offerings belong primarily to the Semiconductor Process Control segment.
otherProductRevenueRevenue from KLA systems that inspect and measure semiconductor patterns, including reticles and masks, critical dimensions and layer alignment. These tools help chipmakers find patterning defects and control lithography processes and are part of Semiconductor Process Control.
patterningRevenueProduct revenue from KLA tools used to image, inspect, test and measure printed circuit boards, IC substrates and packaged chips. It excludes the segment's service revenue, which is reported in KLA's companywide Services category.
printedCircuitBoardAndComponentInspectionRevenueRevenue from KLA's PCB and Component Inspection segment less that segment's cost of revenue. The segment includes PCB, IC-substrate and packaged-component tools plus related services, while most new Display equipment manufacturing has been discontinued.
printedCircuitBoardDisplayAndComponentInspectionGrossProfitTotal segment revenue from KLA's PCB and Component Inspection business, including inspection, metrology, direct-imaging and related services for PCBs, IC substrates and packaged chips. The historical label includes Display, but KLA exited most Display equipment manufacturing and continues mainly to service the installed base.
printedCircuitBoardDisplayAndComponentInspectionRevenueCustomer orders KLA is obligated to fulfill but has not yet recognized as revenue, primarily written orders for semiconductor equipment and services. KLA reports this balance separately from customer deposits and contract liabilities, so it is broader than deferred revenue.
remainingPerformanceObligationsKLA revenue shipped to Asian customers outside China, Taiwan, South Korea and Japan. It is the residual Asian geography and is assigned by customer ship-to location.
restOfAsiaRevenueRevenue from KLA's Semiconductor Process Control segment less the cost of equipment and services sold by that segment. It captures gross profit from inspection, metrology, chemistry-control, analytics and installed-base support before research, sales and corporate expenses.
semiconductorProcessControlGrossProfitTotal revenue from KLA's largest segment, which sells inspection, metrology, chemistry process-control and data-analytics systems plus related services. Customers use these tools from semiconductor research through volume production to detect defects, control processes and improve yields.
semiconductorProcessControlRevenueRevenue from KLA's installed-base support across multiple segments, including warranties, maintenance, spare parts, training and other field services. Unlike equipment sales recognized when control transfers, many service arrangements are recognized over the coverage period.
servicesRevenueRevenue from KLA's Specialty Semiconductor Process segment less the cost of its products and services. The segment supplies vacuum deposition, etch, plasma-dicing and related wafer-processing tools for MEMS, RF and power-semiconductor applications.
specialtySemiconductorProcessGrossProfitProduct-only revenue from KLA's advanced vacuum deposition, etch, plasma-dicing and related wafer-processing tools. These systems serve specialty-chip markets such as MEMS, radio-frequency devices and automotive or industrial power semiconductors.
specialtySemiconductorProcessProductRevenueTotal revenue from KLA's Specialty Semiconductor Process segment, including its wafer-processing equipment and associated services. It is broader than Specialty Semiconductor Process Product Revenue because it also includes the segment's installed-base support.
specialtySemiconductorProcessSegmentRevenueKLA revenue shipped to customers in Taiwan across its semiconductor equipment and service businesses. Geography is assigned by customer ship-to location; Taiwan is also home to KLA's only customer accounting for more than 10% of fiscal 2026 revenue, TSMC.
taiwanRevenueRevenue from KLA defect-inspection and review systems used on patterned and unpatterned wafers. Chipmakers use these tools to locate, classify and analyze defects so they can improve yield from process development through high-volume manufacturing.
