If You Invested $1000 in KLA a Decade Ago, This is How Much It'd Be Worth Now
Read MoreHide Full Article
How much a stock's price changes over time is important for most investors, since price performance can both impact your investment portfolio and help you compare investment results across sectors and industries.
FOMO, or the fear of missing out, also plays a role in investing, particularly with tech giants and popular consumer-facing stocks.
What if you'd invested in KLA (KLAC - Free Report) ten years ago? It may not have been easy to hold on to KLAC for all that time, but if you did, how much would your investment be worth today?
KLA's Business In-Depth
With that in mind, let's take a look at KLA's main business drivers.
Milpitas, CA-based KLA Corporation is an original equipment manufacturer (OEM) of process diagnostics and control (PDC) equipment and yield management solutions required for the fabrication of semiconductor integrated circuits (ICs) or chips. The company has a comprehensive portfolio of products addressing each major PDC subsegment, including photomask or reticle inspection, wafer inspection and defect review, and metrology.
Reticle production is vital to the semiconductor device formation process. Reticles control the precise deposition of materials onto the wafer, which changes its chemical characteristics and imparts specific functions to the ICs created. Inspection and metrology tools measure reticle quality and help improve production yields. The broader use of semiconductors, shrinking form factors and greater chip functionality continue to increase the importance of reticle design and production. Taiwan Semiconductor was the only largest customers in the last three years, accounting for more than 10% of total sales in fiscal 2026, 2025 and 2024.
KLA reported revenues of $13.58 billion in fiscal 2026. Product revenues accounted for 77% of total revenues, while service revenues represented 23%. Semiconductor Process Control generated $12.24 billion, or 90% of fiscal 2026 revenues. Specialty Semiconductor Process and PCB and Component Inspection contributed $584 million (4.3% of revenues) and $750 million (5.5% of reveneus), respectively.
KLA’s two main product lines are defect inspection and metrology. Its defect inspection tools have broad applications in chip, wafer, reticle, storage, compound semiconductor and MEMS manufacturing. Metrology tools gather critical dimension measurements and assess process dimensions such as film thickness, lithography overlay and surface profiling. These products are used in chip, wafer, reticle and solar device manufacturing. KLA also offers products and services.
In addition to new tools, KLA offers refurbished systems that upgrade equipment and improve yields under the KT-Certified program. These tools are sold to IC, reticle, substrate, MEMS and data storage manufacturers.
Although KLA is a major player in each of its served markets, it faces competition from other large equipment suppliers such as Applied Materials and Hitachi High-Tech Corporation.
Bottom Line
Putting together a successful investment portfolio takes a combination of research, patience, and a little bit of risk. For KLA, if you bought shares a decade ago, you're likely feeling really good about your investment today.
A $1000 investment made in October 2016 would be worth $27,085.45, or a gain of 2,608.55%, as of October 8, 2026, according to our calculations. This return excludes dividends but includes price appreciation.
In comparison, the S&P 500's gained 262.24% and the price of gold went up 211.21% over the same time frame.
Analysts are forecasting more upside for KLAC too.
KLA remains positioned to outperform as AI infrastructure spending broadens demand for process control across leading-edge logic, memory and advanced packaging. Rising chip complexity, larger die sizes and tighter defect requirements should increase inspection and metrology intensity. A backlog above $12 billion and improving supply availability provide visibility into 2027, while advanced packaging offers added share gains as front-end tools move into packaging flows. Services add recurring revenue as the installed base expands. KLA's differentiated portfolio, operating leverage and capital-return framework support long-term earnings growth. Risks include semiconductor cyclicality, customer concentration, export controls, competition and component costs, but structural demand and share opportunities remain more compelling.
The stock has jumped 7.61% over the past four weeks. Additionally, no earnings estimate has gone lower in the past two months, compared to 1 higher, for fiscal 2026; the consensus estimate has moved up as well.
