What's Driving KLAC's Business? Latest 10-Q Breakdown

✓ 15/15 datapoints verified

AI-extracted from KLA CORP's 10-Q filed 2026-04-30 — Q3 FY2026 (quarter ended March 31, 2026). Every figure is machine-verified against the filing text on SEC EDGAR.

KLA's Q3 revenue reached $3.42B (+11% YoY) driven by memory and foundry/logic demand; net income was $1.20B (+10% YoY).

Biggest Revenue Drivers

Total revenue: $3.42B+11% YoY

Semiconductor Process Control$3.08B+13% YoY

Increased revenue from memory customers (particularly DRAM led by high-bandwidth memory) and foundry/logic, plus higher service revenues from growing installed base.

Specialty Semiconductor Process$164M+5% YoY

Timing of shipments and higher service revenues from increasing number of tools in installed base.

PCB and Component Inspection$168M-1% YoY

Display business exit offset by increased revenues from PCB products and higher service revenues from growing installed base.

Largest Expense Items

Cost of revenues$1.33B+13% YoY

Higher tariffs, installation and warranty costs, partially offset by lower inventory-related charges.

Research and development$389M+15% YoY

Increases in employee-related expenses ($35.7M) from additional headcount and higher compensation, plus engineering project material costs.

Selling, general and administrative$291M+17% YoY

Provision for credit losses ($23.1M), employee-related expenses ($14.9M), and facilities-related expenses ($6.6M).

Margins: Gross margin decreased 50 bps to 61.1%, primarily due to higher tariffs and installation/warranty costs, partially offset by revenue volume leverage. The company expects escalating DRAM chip costs to continue negatively impacting gross margin in calendar 2026, though expects this to be transitory.

Watch Items from the Filing

China revenue exposure: 24.3% of Q3 revenues from China; subject to U.S. export controls under 2022-2025 BIS Rules restricting advanced semiconductor manufacturing equipment sales.
DRAM chip shortage: Recent discontinuation by suppliers has caused dramatic price increases; estimated additional costs will adversely impact gross margin in calendar 2026.
Two customers represented 19% and 11% of Q3 revenues; customer concentration remains a risk.
Strong cash generation: Operating cash flow of $3.24B YTD; $10.31B remaining repurchase authorization and $4.96B in cash/equivalents/securities provide strong liquidity.
