👉 Breaking Down KLA Corp ($KLAC)

Together with F4 Uranium

Hi everyone,

I hope the coffee is strong and the portfolio is green.

Most people have never heard of the company we are covering today, and that is exactly the point. While everyone fixated on Nvidia and the hyperscalers, a quiet inspection business out of Milpitas, California nearly tripled. KLA is up roughly 121% over the past twelve months and then split its stock ten-for-one in June. If you blinked, a $1,763 share quietly became ten $176 shares, which then climbed back all the way up to $300.

As a reminder, this specific deep-dive is written by the GRIT team and is not the exclusive work of Head Analyst Austin Hankwitz.

KLA Corporation sits in one of the strongest competitive positions in all of technology, and almost nobody talks about it. The semiconductor world is dominated by five equipment giants: ASML sells the lithography that prints chips, Applied Materials and Lam Research sell the deposition and etch tools that build them, and KLA owns the inspection and metrology layer that checks whether any of it was done correctly. At the leading edge, where a single defect can ruin a $30,000 chip, that checking step is the difference between a profitable fab and a financial disaster.

That positioning has produced numbers most companies can only dream about. KLA controls roughly 58% of the process control market, a share that has expanded by 360 basis points since 2021 and now sits about seven times larger than its nearest competitor. On trailing revenue of about $12.2B, the company earns net margins above 33% and returns on equity near 95%, generates more than $4B in free cash flow a year, and hands over 90% of it back to shareholders.

The catalyst now is artificial intelligence. Every AI accelerator, every stack of high-bandwidth memory, every advanced package that glues them together has to be inspected, and the more complex the chip, the more inspection it needs. Management raised its 2030 revenue target to $26B, said advanced packaging process control revenue will nearly double to about $1B in 2026, and the CEO described customer urgency he has not seen in a 38-year career. The catch, as always, is price. At roughly 70 times trailing earnings in a historically cyclical business, the market has already priced in a lot of perfection.

The Uranium Market Is Entering a New Chapter

As countries around the world expand nuclear power generation to meet growing electricity demand, uranium has re-emerged as one of the world's most strategically important commodities. More than 80 nuclear reactors are currently under construction globally, with hundreds more planned or proposed as nations pursue reliable, low-carbon energy sources.

F4 Uranium (TSXV:FFU | OTC:FFUCF) is a Canadian exploration company focused on discovering high-grade uranium deposits in Saskatchewan's Athabasca Basin—widely regarded as the world's premier uranium district. The company controls a portfolio of exploration properties across the basin and is led by the technical team behind four major uranium discoveries in the region.

As governments prioritize energy security, data center power demand continues to accelerate, and utilities seek long-term uranium supply, many investors are taking a fresh look at exploration companies operating in proven mining jurisdictions with significant discovery potential.

F4 Uranium (TSXV:FFU | OTC:FFUCF) has also recently been featured by both ZeroHedge and Insider Stock Pick, highlighting the company's experienced leadership team and exploration strategy.

Why Now 👉 the split, the AI surge, and four straight beats

Companies do not split their stock ten-for-one when things are going badly. They do it when the price has run so far that ordinary investors feel locked out. That is exactly what happened here. Before the split took effect on June 12, KLA traded near $1,763 a share. Management approved the ten-for-one forward split, lifted the quarterly dividend 21%, and tacked on an additional $7B buyback authorization for good measure. The message was confidence, and the market sent shares up nearly 32% in the week around the split alone.

Underneath the financial engineering is a genuinely strong business. KLA has now beaten Wall Street estimates four quarters in a row. The most recent report, for the March 2026 quarter, delivered $3.42B in revenue, up about 11% year over year, with non-GAAP earnings of $9.40 per share against a $9.15 consensus. Management guided the June quarter to $3.575B and told investors that calendar 2026 process control systems revenue should grow more than 20%, with the overall company growing in the high teens. Then it said 2027 should grow even faster.

The reason is simple. The wafer fabrication equipment market, KLA's pond, is now expected to clear $140B in 2026, lifted by the scramble to build enough fabs and packaging capacity for AI. CEO Rick Wallace put it bluntly on the earnings call, saying he had never seen this level of customer urgency to secure tool slots in his entire career. When the company that inspects every chip says demand is unprecedented, it is worth paying attention.

Overview👉 from photomask inspection house to process control king

KLA was incorporated in 1975 and spent decades as a niche player inspecting the photomasks and reticles used to pattern chips. The modern company was forged in 1997 when KLA merged with Tencor to form KLA-Tencor, combining defect inspection with metrology, the science of measuring whether a chip's microscopic features came out the right size and in the right place. The company dropped the Tencor name in July 2019 and is now simply KLA, headquartered in Milpitas, California with about 15,100 employees.

What KLA actually sells is certainty. Its tools scan wafers and reticles for defects, measure film thickness and pattern dimensions down to the atomic scale, and feed that data back into the manufacturing line so chipmakers can correct problems before they ruin an entire batch. In an industry where a leading-edge fab can cost $20B to build and a single bad run wastes weeks of output, catching a defect early is worth far more than the inspection tool costs. That is the quiet leverage at the heart of this business.

Rick Wallace has run the company since January 2006, having joined as an applications engineer in 1988 and worked his way up. Under his nearly two decades as CEO, KLA's process control share has climbed from the low-40s to roughly 58%, all while keeping operating margins above 40%. CFO Bren Higgins has built a capital return machine that has handed shareholders more than $20B over the years. This is a team that has compounded patiently and let the numbers do the talking.

How Do They Win👉 the moat behind the inspection layer

KLA's advantage starts with a clean division of labor among the equipment giants. Think of chipmaking in three verbs: print, make, and inspect. ASML prints the patterns with lithography. Applied Materials and Lam Research make the structures with deposition and etch. KLA inspects everything, and it does so with almost no overlap from the others. That focus lets KLA pour its entire research budget into one mission, while rivals split their attention across many tool categories.

The moat deepens with every shrink in chip geometry. As features get smaller and chips stack into three dimensions, defects become harder to find and more catastrophic when missed, so each new technology node requires more inspection steps, not fewer. Once a fab qualifies a KLA tool into a production line, ripping it out and requalifying a competitor's tool risks yield, schedule, and millions in lost output. Switching costs are brutally high.

Then there is data. KLA's installed base has been scanning wafers for decades, building a reservoir of defect signatures and process knowledge that a new entrant cannot replicate. The software that classifies defects and recommends corrections gets smarter the more wafers it sees, which feeds a flywheel: more tools generate more data, and better data wins more tools. Layer on a services business that grows with every machine in the field, and you get a company whose lead compounds rather than erodes.

Business Units👉 the three segments and the services engine

KLA reports through three operating segments. The crown jewel is Semiconductor Process Control, which houses the wafer inspection, patterning, metrology, and reticle inspection tools that define the company. Wafer inspection alone made up about 51% of total revenue last quarter at $1.74B, up 16% year over year, while patterning systems contributed roughly 18%. This segment is where KLA's near-monopoly lives and where the AI demand is landing hardest.

The second segment, Specialty Semiconductor Process, sells etch, deposition, and plasma dicing tools aimed at specialty devices and advanced packaging rather than the bleeding-edge logic nodes. The third, PCB and Component Inspection, serves printed circuit boards and electronic packaging with direct imaging, inspection, and additive printing systems. These two are smaller than the flagship segment but extend KLA's reach across the broader electronics supply chain and diversify it beyond the most cyclical leading-edge spending.

Running underneath all three is the services business, which is the unsung hero of the model. Service revenue reached $775M last quarter, up almost 16% year over year, and now accounts for nearly 23% of the total. Every tool KLA ships becomes an annuity, generating maintenance, upgrades, and spare-parts revenue for a decade or more. That recurring stream smooths out the lumpiness of equipment orders and gives the company a base of revenue that holds up even when fab spending cools.

How Do They Make Money👉 systems, services, and where revenue comes from

The economics break into two streams. First is the systems business: high-value inspection and metrology tools that can run several million dollars each, sold to fabs as they add or upgrade capacity. This is the cyclical, order-driven part of the company, and the part riding the AI wave right now. Second is the services stream, a recurring, higher-margin annuity tied to the growing installed base. Together they produced trailing revenue of about $12.2B with a non-GAAP gross margin north of 62%.

Geographically, the revenue map tells the story of where leading-edge chips get built. In the March quarter, Taiwan led at 26% of revenue, followed by China at 24%, Korea at 20%, and North America at 12%, with Europe, Japan, and the rest of Asia splitting the remainder. Taiwan and Korea reflect the foundry and memory giants, while China remains a large and politically sensitive slice we will return to in the risks section.

The capital return policy is the final piece. KLA targets returning over 90% of free cash flow to shareholders, and last quarter alone it sent back roughly $875M through buybacks and dividends. With the dividend just raised 21% before the split and a fresh $7B buyback in hand, the company is leaning hard into giving cash back rather than hoarding it, a clear sign of confidence in the durability of its cash generation.

By The Numbers👉 the quarter, the guidance, and the model

Here is the snapshot of the most recent quarter and the road ahead, with everything in split-adjusted context where it matters:

The valuation is the elephant in the room. At roughly $249 post-split, KLA trades near 70 times trailing earnings, about 55 times EV/EBITDA, and well above its own history. Even bulls concede the multiple leaves little room for disappointment in a business that has always been cyclical. You are paying a premium for a near-monopoly at the exact moment its end market is booming.

Bonus Deep Dive👉 advanced packaging and the AI inflection

If you want to understand why this stock tripled, look at advanced packaging. As classic transistor scaling slows, chipmakers increasingly stitch multiple chips together into a single advanced package, stacking high-bandwidth memory next to a processor to feed AI accelerators the data they crave. Every TSMC, Samsung, and leading memory fab building this capacity needs to inspect each layer and connection, and that is a new and rapidly growing market for KLA.

The numbers here are the most exciting in the whole story. KLA projects its advanced packaging process control revenue will nearly double to about $1B in 2026, up from $635M in 2025. The company gained 14 percentage points of market share in advanced wafer-level packaging and grew that revenue line roughly 70% year over year. This is KLA taking its core inspection expertise and aiming it directly at the part of the chip that makes AI accelerators work, at the exact moment demand for those accelerators is exploding.

The strategic point is that AI does not just lift KLA's existing business, it expands the surface area that needs inspecting. A simple chip needs a handful of inspection steps. A stacked, packaged AI device with billions of microscopic connections needs far more, and the cost of a defect in a $30,000 accelerator is enormous. That is why management can credibly talk about a $26B revenue target by 2030. The more complex chips get, the more KLA sells, and chips are only getting more complex.

Risks👉 what could break the story

• China exposure. China made up 24% of last quarter's revenue, and tightening US export controls could cut off a meaningful slice of demand with little warning. This is the single largest geopolitical wildcard in the model.

• Valuation. At roughly 70 times trailing earnings in a cyclical equipment business, the stock is priced for continued execution. Any stumble in growth or margins could trigger a sharp re-rating, and bears point to support near $180 post-split.

• Cyclicality. Semiconductor equipment has always been boom-and-bust. The AI cycle feels durable today, but fab spending can cool quickly, and KLA's systems revenue would feel it first.

• Margin headwinds. Elevated DRAM prices are creating a roughly 100 basis point drag on gross margins for several quarters, and tariffs add another 50 to 100 basis points of pressure.

• Customer concentration. Revenue leans heavily on a handful of leading-edge customers in Taiwan and Korea. A capex pause at TSMC or Samsung would ripple straight through results.

• Insider selling. CEO Rick Wallace sold about $8.1M of stock in May, his largest sale in a year, and insiders have logged 19 sells and zero buys over the past twelve months. Not a thesis-killer, but worth noting at these levels.

Wrapping Up👉 the bull and bear in one place

The bull case is clean and powerful. KLA owns the inspection layer of chipmaking with a roughly 58% share that keeps growing, its tools get more essential with every shrink and every stacked package, and the AI buildout is expanding its market faster than at any point in the CEO's long career. Add 60%-plus gross margins, $4B-plus in annual free cash flow, a 90%-plus capital return policy, and a credible path to $26B in revenue by 2030, and you have one of the highest-quality compounders in the semiconductor complex.

The bear case is just as clean: you are paying about 70 times earnings for a cyclical business right as its cycle peaks, with a quarter of revenue exposed to China and insiders heading for the exits. Both sides are right, which is what makes this one interesting. The business is genuinely exceptional. The price assumes it stays that way for a very long time. Where you land depends on whether you see the AI inspection wave as a multi-year secular shift or a cycle that has already been fully priced.

As always, this is not investment advice, just one writer's research to help you do your own. Do the work, size your positions sensibly, and never let a great story talk you out of a sober look at the price.
