Analysis

## The Short Answer Is Yes [KLA Corp](/company/kla-corp/) is an American company. It is headquartered in Milpitas, California, trades on a US stock exchange, and has built its business around one of the most critical links in the American semiconductor supply chain: making sure computer chips are built correctly. ## Headquarters in Silicon Valley KLA's headquarters sits in Milpitas, California, placing it squarely in the Silicon Valley corridor that has anchored American chip innovation for decades. The company was founded in 1997, though its roots as a publicly traded firm stretch back further. ## Listed on the NASDAQ KLA trades publicly under the ticker **KLAC** on the NASDAQ, and it first went public all the way back in October 1980. A US stock exchange listing doesn't by itself make a company American, but combined with a California headquarters, it's a strong marker of domestic roots and public accountability to US investors and regulators. ## What KLA Actually Builds KLA is one of the largest semiconductor wafer fabrication equipment, or WFE, manufacturers in the world. Rather than making the chips themselves, KLA makes the machines that inspect semiconductor wafers during both research and development and full-scale manufacturing, catching defects and verifying measurements with extreme precision. ### A Majority Share of a Niche Market Within the specific niche of semiconductor process control, KLA holds a majority share of the market. It also has a smaller presence in the etch and deposition segments of the broader WFE industry, rounding out its footprint in chip-manufacturing technology. ## Who Relies on KLA KLA's customer list includes the largest chipmakers in the world, among them TSMC and Samsung. That customer base underscores how central KLA's inspection and measurement tools are to the global chip industry, even though KLA itself isn't a household name the way its customers are. ## A Sizable American Workforce KLA employs approximately 15,200 people. That workforce supports a company whose tools are quietly essential to an industry most people only think about when they buy a new phone or laptop. ## The Numbers Behind the Company In fiscal year 2025, KLA reported revenue of $12.2B and net income of $4.1B. Its total assets stood at $16.1B, and its market capitalization reached $275.0B. These figures reflect a company with substantial scale relative to its specialized corner of the semiconductor equipment business. ## Verified in the Directory KLA Corp is listed in the americancompanies.com directory of US-based companies, a resource that vets and organizes companies by their domestic headquarters and operations. Its inclusion there aligns with the headquarters and listing details laid out above. ## The Bottom Line Between its Milpitas headquarters, its NASDAQ listing, and its long operating history dating back to a 1980 IPO, KLA checks every conventional box for being classified as an American company. It may operate behind the scenes of the chip industry, but its address, its stock ticker, and its workforce are firmly rooted in the United States.
