Applied Materials Stock: Straight A's on All Five Buffett Criteria — but the 45 Percent Profit Jump Didn't Come From the Factories

There is an investor trap that is especially well camouflaged because it feels like diligence: the guarantor trap. It works like this: a great name appears to vouch for a stock — "passes the Buffett criteria," "Graham would have bought this," "a Munger kind of business" — and from that moment on, your brain stops examining the company and starts trusting the guarantor. The treacherous part: the guarantor has no idea. A checklist from a book is a sieve, not a blessing. Applied Materials, Inc. (Nasdaq: AMAT) is the perfect test case: in our in-house Buffett criteria scanner, the stock passes all five tests and ranks no. 8 of the U.S. selection (as of July 18, 2026). So let's make a deal: before you outsource your homework to the most famous name in stock market history, we read together what the company itself filed, under penalty of law, with the U.S. securities regulator, the SEC — the annual reports (10-K) for fiscal years 2025 and 2024 and the quarterly reports (10-Q) through April 26, 2026. Both things are in there: one of the best balance sheets we have ever covered in this series. And a 45 percent profit jump of which, on close inspection, only 0.2 percentage points came from the operating business. In the end, you decide whom to trust here.

What Applied Materials actually does — the toolmaker behind every chip

Applied Materials, founded in 1967 and headquartered in Santa Clara, California, is the world's largest maker of semiconductor manufacturing equipment, with about 36,500 employees (as of October 26, 2025). The company calls its field "materials engineering": machines that deposit, remove, dope and measure wafer-thin layers of material on silicon — the process steps from which a chip is made in the first place. Its own claim in the annual report is immodest and still fairly accurate: the leader in the solutions used to produce "virtually every semiconductor in the world." Important framing: Applied Materials sells neither chips nor artificial intelligence — it sells the factory equipment to those who build both: foundries, logic and memory chipmakers. In our company-by-company AI rating we accordingly file the company under "uses AI": its own filings describe AI as a demand driver and as a tool inside products and operations, not as a revenue source. Reporting comes in two segments plus a remainder: Semiconductor Systems (new equipment, $20.798 billion of fiscal 2025 revenue, 73 percent), Applied Global Services (service, spares and upgrades for the installed fleet, $6.385 billion, 23 percent) and "Corporate and Other" (mostly display equipment, $1.185 billion). One quirk that helps with reading the numbers: the fiscal year ends on the last Sunday in October — "fiscal 2025" ended on October 26, 2025, and the current "fiscal 2026" is already half over by mid-2026.

How tightly this toolmaker is wired into the AI build-out is something we have covered from two other angles in this series: at direct competitor Lam Research, which sits higher in the same scanner, and at memory maker Micron, which sits on the customer side of such machines. Which brings us to the central tension of this analysis, running through every chapter: The quality report card is real — margins, balance sheet and cash flow are world class. But the latest profit surge comes mostly from a stock portfolio and a tax effect, a third of revenue hangs on two customers, and the valuation has detached itself from the machinery business.

Where the stock shows up in our scanner

Every day we run roughly 3,500 stocks through our scanners. As of July 18, 2026, Applied Materials has two hits, and the first is the reason for this analysis: rank 8 in the Buffett criteria scanner (U.S. selection, 25 U.S. hits of 104 total). To replicate it yourself: open the scanner, set the country filter to "US" — Applied Materials sits in the top third of the list. The scanner tests the five screenable criteria from Mary Buffett's "Buffettology," and it is worth translating them one by one, because AMAT passes every single one with room to spare: a return on equity of about 40 percent (required: at least 15 — $100 of equity generates $40 of annual profit here), a debt-to-equity ratio of 0.32 (allowed: up to 0.5 — only 32 cents of financial debt per dollar of equity), an EBIT margin around 32 percent (required: 10 — of every revenue dollar, 32 cents remain as operating profit), positive earnings per share rising from the oldest to the newest of all six recorded quarters ($1.45 to $3.51), and clearly positive free cash flow. The second hit provides confluence: the Altman-Z balance fortress scanner, with a Z-score around 13.6 — a bankruptcy early-warning gauge whose danger zone starts below 1.8; 13.6 is about as far from that as an industrial company can get without net debt. Add a Piotroski F-Score of 7 of 9 (a nine-point test of the direction of the books — 7 is good; rock-solid starts at 8). But remember the principle, because it is the connecting thread of this piece: A criteria sieve tests the company of yesterday and today — not today's price, and not the source of tomorrow's profit. That is exactly why we now read the filings.

The numbers over the years — honestly appraised

First, what genuinely impresses — and there is a lot of it. Applied Materials does not grow spectacularly, but with a steadiness that has few equals in the cyclical semiconductor equipment industry: revenue of $26.517 billion (fiscal 2023), $27.176 billion (2024), $28.368 billion (2025, up 4 percent) — the third record in a row. Gross margin climbed from 46.7 to 47.5 to 48.7 percent along the way, and operating income reached $8.289 billion (29.2 percent margin). Operating cash flow in fiscal 2025 was $7.958 billion; after $2.3 billion of capital expenditures, roughly $5.7 billion of free cash flow remained. And the current fiscal year keeps delivering: in the second quarter (through April 26, 2026), revenue rose 11 percent to $7.910 billion, the core segment's gross margin hit 54.7 percent, and the order and service backlog already stood at $15.0 billion at the end of fiscal 2025. A second, often overlooked stabilizer: the services business, Applied Global Services — maintenance, spares and long-term contracts for the globally installed fleet — contributes almost half of that backlog and grew 17 percent in the second quarter; like an elevator company, Applied keeps earning on the service contract even when nobody is ordering new elevators. So much for the report card the Buffett scanner sees. Now for what it does not see:

In the first half of fiscal 2026 (through April 26, 2026), Applied Materials reported $4.832 billion of net income — up 45 percent year over year. Operating income over the same period: $4.354 billion after $4.344 billion — up 0.2 percent. A scissors of 45 versus 0.2 does not open on the factory floor. Where it opens is the subject of the next chapter — and it is the most important finding of this analysis. Remember the image: The sieve measures that profit is rising. It does not ask what the profit is made of.

What the filings say — the uncomfortable truths

Uncomfortable truth no. 1: The profit jump comes from the portfolio and the tax line — not from operations

The quarterly report names the driver of the profit jump itself, in a single dry sentence:

"Interest and other income (expense), net in the three and six months ended April 26, 2026 increased compared to the same periods in the prior year, primarily driven by higher net unrealized gain on equity investments."

— Applied Materials, Inc., SEC quarterly report 10-Q as of April 26, 2026, Item 2 "Management's Discussion and Analysis"

The numbers behind it: the line "interest and other income" exploded from $229 million to $1.337 billion in the half-year — including $1.157 billion of unrealized gains on publicly traded stocks the company holds in its portfolio (cost basis $965 million, market value $2.248 billion at the balance sheet date; which stocks they are, the report does not say). "Unrealized" means: nothing was sold, no cash came in — U.S. accounting rules require the price swings of such positions to run straight through the income statement. Then there is the second lever: the tax rate fell from 25.2 to 13.0 percent — the prior year was distorted by a one-off, as the first quarter of fiscal 2025 carried an extraordinary 44.1 percent rate from the remeasurement of deferred tax assets tied to new tax incentive agreements in Singapore. Strip both effects out, and almost nothing of the 45 percent jump remains: operations grew 0.2 percent — solid, but no breakout. None of this is illegal or hidden; it is all in the filing. But a stock portfolio works in both directions: the same accounting that just poured $1.2 billion into net income will pull it back out in the next correction. Growth the stock market lends you, the stock market can recall at any time.

Uncomfortable truth no. 2: A $253 million penalty for China shipments — and an export ban that is merely suspended

The second footnote no scanner in the world sees sits under "Legal Matters" in the quarterly report:

"As previously disclosed, on February 11, 2026, we entered into a settlement agreement with the U.S. Commerce Department Bureau of Industry and Security (BIS) to resolve its inquiry relating to certain China customer shipments and export controls compliance and agreed to pay BIS an amount of $253 million, which we paid in full during our second quarter of fiscal 2026."

— Applied Materials, Inc., SEC quarterly report 10-Q as of April 26, 2026, Note 13 "Guarantees, Commitments and Contingencies" (Legal Matters)

The $253 million is digestible — it equals a bit over one percent of annual revenue and shaved about two points off the core segment's half-year margin. The real risk is in the sentence that follows: the settlement includes a denial order that is merely suspended — it is only waived three years after issuance, and only if Applied Materials completes the agreed internal audits of its export controls program on schedule. A denial order is the sharpest instrument of U.S. export enforcement: an outright ban on exporting certain products. In everyday terms: the company did not just pay a fine — it is now driving with a probationary license for three years, where the next violation takes the license away. And the license here is the China business: $8.529 billion of revenue, 30 percent of the company in fiscal 2025 (prior year: $10.117 billion and 37 percent — the export controls are already biting).

Uncomfortable truth no. 3: Two customers pay a third of the bill — and the AI boom is, by the company's own filing, hard to forecast

Who buys these machines? The annual report names no names, but it does name a number that should make you pause:

"During fiscal 2025, two customers accounted for approximately 19% and 15%, respectively, of our net revenue."

— Applied Materials, Inc., SEC annual report 10-K for fiscal year 2025, Item 1 "Business" (Customers)

A combined 34 percent of revenue from two buyers — picture a baker who sells every third roll to just two wholesale customers: their construction plans decide his year. This is structural in the industry (only a handful of companies worldwide build multi-billion-dollar fabs), and you can guess the names behind it — the filing deliberately does not provide them. But the concentration has been rising: in fiscal 2024, the two largest customers stood at 12 and 11 percent. The same filing also tells you how dependable the AI demand driving those customers is — with a candor you have to credit the company for:

"Artificial intelligence (AI) and technologies related to AI are a significant demand driver for the industries we serve. AI is evolving rapidly and the expected timing and amount of investments related to AI can change significantly. As a result, it is difficult to accurately forecast demand for our products related to AI."

— Applied Materials, Inc., SEC annual report 10-K for fiscal year 2025, Item 1A "Risk Factors" (Business and Industry Risks)

Hold these three facts next to each other: AI demand that is hard to forecast, two customers with 34 percent of revenue, and a China business of 30 percent under export supervision with probation conditions. Each of these dependencies is manageable on its own — together they explain why a company with this balance sheet quality remains a cyclical. For a reminder of what that cycle looks like from the inside, look one level deeper in the supply chain: in our Benchmark analysis, Applied Materials itself appears as the anchor customer on whom every seventh invoice of that contract manufacturer depends. Concentration runs through this industry like a watermark — at every level.

Valuation: What the market charges for the report card

Now for the price tag. In mid-July 2026 the Applied Materials share cost about $670, for a market value around $530 billion (all valuation figures: data as of July 18, 2026) — after a share-price gain of roughly 245 percent in twelve months. That works out to: a price-to-earnings ratio near 59 (on trailing twelve-month earnings), a price-to-sales ratio near 18, a price-to-book ratio near 22 and a price to free cash flow near 99. For context: for long stretches of the past decade, the equipment maker traded at 15 to 25 times earnings; the current multiple prices the machinery company like a software growth stock. And here it is worth watching what the company does with its own money: share repurchases were throttled to $737 million in the first half of fiscal 2026 (prior-year period: $2,999 million; just $400 million in the second quarter after $1,685 million) — against an open authorization of $13.2 billion. In fiscal 2025, at much lower prices, the same company bought back $4.9 billion. No official reason is given; as a quiet valuation verdict from management, it reads clearly enough. The dividend was raised 15 percent to $0.53 per quarter in March 2026 — about a 0.3 percent yield at the current price. The 39 analysts tracked by the data provider average a "buy" (consensus 1.2 on a scale where 1 means "strong buy") — the professionals' view is unanimously optimistic; for a stock that has just three-and-a-half-folded, unanimity is more choir than second opinion.

Opportunities and risks at a glance

What speaks for Applied Materials:

• Quality that passes all five Buffett criteria with room to spare: return on equity around 40 percent, debt-to-equity 0.32, EBIT margin around 32 percent, six quarters of rising earnings, positive free cash flow (data as of July 18, 2026) — plus an Altman-Z around 13.6 and a Piotroski score of 7 of 9.
• Three revenue records in a row ($26.5 → $27.2 → $28.4 billion, fiscal 2023–2025) with a rising gross margin (46.7 → 48.7 percent); Q2 of fiscal 2026 up 11 percent with a 54.7 percent segment gross margin.
• The service anchor: Applied Global Services ($6.4 billion of fiscal 2025 revenue, up 17 percent in the latest quarter) and a $15.0 billion backlog smooth the equipment cycle.
• The AI build-out as structural tailwind: no new fabs, no AI chips — and virtually no fab gets built without Applied Materials equipment; $3.570 billion of fiscal 2025 R&D spending defends that position.
• Capital discipline: essentially zero net financial debt ($12.9 billion of cash and investments as of October 26, 2025), a 15 percent dividend hike, and buybacks that were not forced at record prices.

What speaks against it:

• The earnings quality of the current year: of the 45 percent first-half jump, only 0.2 percentage points came from operations — the rest from $1.157 billion of unrealized portfolio gains and a tax rate that fell from 25.2 to 13.0 percent; both effects can reverse.
• Regulatory probation risk: a $253 million BIS settlement (February 2026) with a suspended denial order over three years — a direct lever on the top line with China at 30 percent of fiscal 2025 revenue.
• Customer concentration: two buyers at 19 and 15 percent of revenue (fiscal 2025; prior year: 12 and 11 percent) — the capex cycles of a few companies decide the year.
• A valuation without a safety net: P/E near 59, price-to-sales near 18, price to free cash flow near 99 after a 245 percent twelve-month run (data as of July 18, 2026) — historically the cyclical traded at 15 to 25 times earnings.
• AI demand is, per the company's own 10-K, "difficult to accurately forecast" — a capex pause by a few large customers would hit equipment revenue and the valuation at the same time.

A human conclusion

Back to the guarantor trap from the opening. Its core is not that the criteria lie — they do not: Applied Materials has one of the best balance sheets in this series, genuine pricing power and a services business that cushions the cycle. Its core is that a borrowed name lets you skip two examinations no sieve in the world performs: the price, and the quality of the earnings. Scanner rank 8 says "passed: returns, leverage, margin, earnings streak, cash flow." It does not say "a 45 percent profit jump, 0.2 of it from the factories." It also does not say "59 times earnings for a company on probation with the export regulator." Both are in the same documents — just in the footnotes, not the headline. The honest math looks like this: you get the indispensable toolmaker of the chip industry, with world-class metrics and a structural AI tailwind — at a growth-stock price, with an income statement currently being inflated by the stock market itself, and a third of the business in the hands of two customers and one regulator. Whether operating growth catches up with the valuation before the portfolio or the cycle catches up with it — that is the bet, and no checklist takes it off your hands. Instead of the label, read the next quarterly reports (10-Q): the "interest and other income" line (how much of the profit is paper?), the China share, and the progress of the BIS audits. What you make of it is your decision. And that is exactly as it should be.
