// Full episode scriptWelcome to Beta Finch, your AI-powered earnings breakdown! I'm Alex, joined as always by Jordan, and today we're digging into KLA Corporation — ticker KLAC — and their September quarter results. And Jordan, I'll just say it up front: this one's a blowout.
It really is, Alex. Record revenue, record margins, and a 2027 outlook that sounds almost aggressive. I'm excited to get into it.
Before we do — quick housekeeping. This podcast is AI-generated content for educational and entertainment purposes only. Nothing we discuss should be considered investment advice. Always do your own research and consult a qualified financial advisor before making any investment decisions.
Important stuff. Okay, let's talk numbers.
So KLA makes process control and inspection equipment for semiconductor manufacturing — basically the tools that check wafers for defects as chipmakers build increasingly complex chips. This quarter, September 2026, they posted revenue of $4.14 billion. That's a record, up 13% sequentially and 29% year-over-year.
And here's the headline that really jumped out at me — operating margin above 46% for the first time ever in company history. 46.1%, to be exact, up 240 basis points from the prior quarter.
That's a remarkable number for a hardware company. Gross margin came in at 62.7%, non-GAAP EPS was $1.22, GAAP EPS $1.18 — both beating the midpoint of guidance. Free cash flow was $1.34 billion. Pretty much every metric beat expectations.
And it's not slowing down — guidance for the December quarter is about $4.7 billion in revenue, plus or minus $200 million. That implies the back half of calendar 2026 grows roughly 25% over the first half. That's a massive acceleration.
Right, and CEO Rick Wallace was clear about why: AI infrastructure investment, leading-edge foundry and logic demand, and rising "process control intensity" — basically, as chips get more advanced and complex, you need more inspection and metrology steps per wafer. That plays directly into KLA's wheelhouse.
Let's talk about the big strategic story here, though — because the 2027 outlook is really what's driving the stock. CFO Bren Higgins raised the 2026 wafer fab equipment market forecast to the mid-$150 billion range, and — this is the eye-popping part — they now expect the 2027 wafer equipment market to exceed $200 billion.
Exceed $200 billion. That's a jump from an already-raised 2026 number. And management said their visibility into 2027 is "unprecedented" — that's a strong word to use on an earnings call.
It really is, and it's backed up by tangible stuff — growing backlog, a strengthening sales funnel, and numerous greenfield fab projects across foundry, logic, and DRAM. This isn't just a vibes-based forecast; customers are locking in multi-year capacity commitments.
One thing I found fascinating from the Q&A was the DRAM conversation. An analyst pointed out that KLA's DRAM-related revenue jumped around $450 million quarter-over-quarter, which is a huge swing for a market where KLA has a relatively modest overall share. Rick Wallace explained it's about rising "intensity" — DRAM makers, especially with HBM for AI chips, are now treating yield almost like "printing money," as Bren put it, so they're buying a lot more inspection equipment per wafer than they used to.
That intensity comment stuck with me too. Bren actually said some DRAM products now see process control intensity similar to leading-edge logic — that's a real structural shift, not just a cyclical blip. And they expect memory to be about 60% of the business mix in the second half of 2027.
Advanced packaging was another bright spot — on track for $1.1 billion in revenue for 2026, growing over 70% year-over-year, nearly double the growth rate of the overall advanced packaging market. As chips move toward more complex 3D stacking and hybrid bonding, that requires finer and finer inspection sensitivity, and KLA says they're well positioned there.
Now, it wasn't all upside — let's talk about the gross margin headwind, because analysts pushed hard on this. KLA's long-term target is 63-64% gross margin, and they're currently guiding to 62.5% for December. The culprit? Memory chip costs — ironically, the memory KLA needs to build the image processing systems inside its own tools has gotten more expensive because of the broader AI-driven memory shortage.
It's a funny twist — they're benefiting from the DRAM boom on the demand side but getting squeezed by it on the cost side.
Exactly. Management says they're working on "memory optimization" engineering to use less of it in their systems, plus pricing initiatives to pass along value, but they don't expect real margin recovery until mid-to-late 2027 into 2028.
There was also a good exchange about supply chain constraints. Multiple analysts asked whether KLA can actually keep up with this demand. Bren and Rick were pretty candid — they said they've been "short" on supply most of the year, particularly on long-lead-time optical components, with lead times averaging around 12 months and even longer for their top-tier systems.
But they were adamant about one thing — their stated goal is to never be the bottleneck in the industry. They're investing heavily: new capacity at every manufacturing site, a brand-new campus in India, and CapEx they expect to run between $600 million and $800 million annually going forward.
And Rick made an interesting point — sometimes it's not even about KLA's shipping capability. Some customers are ready for equipment but their actual cleanroom construction or power infrastructure isn't ready yet. So the bottleneck can shift around the ecosystem.
That's a good reality check for anyone modeling out hyper-aggressive growth — building fabs takes time regardless of how fast the equipment makers can move.
So what does this mean for investors going forward? KLA is clearly riding the AI infrastructure wave from a picks-and-shovels angle — they're not making AI chips, but they're essential to making sure the chips going into AI data centers actually work and yield well.
And the long-term framing matters too — management reiterated their 2030 target model, and Bren even noted that some of those assumptions, like the $220 billion wafer equipment market estimate, now look conservative given where 2027 is shaping up. That's a notable signal of confidence.
The combination of record margins today plus a multi-year runway of greenfield fab investment is clearly what's got the market excited — KLAC shares were up over 3% on this report.

Great breakdown, Jordan. Big picture: KLA delivered a historic quarter, raised both near-term and next-year outlooks, and management sounds more confident than ever about a multi-year AI-driven capital spending cycle — even as they navigate some real supply chain and margin puzzles along the way.
We'll be watching closely for that January call when they give more detail on 2027 segment expectations. Should be a fascinating next few quarters.
That's it for this episode of Beta Finch. Thanks for listening, and we'll catch you next time!
See you then!
