Why Did Applied Materials Stock Nearly Triple On Single-Digit Trailing Revenue Growth?
Applied Materials (AMAT) stock has returned about 180% over the past year, against roughly a fifth for the S&P 500. Nothing in the trailing revenue looks like that. Revenue over the trailing twelve months grew 7.8%. What re-rated the shares was a forecast management raised twice between February and August, and the reason that forecast kept rising is the part worth knowing.
Applied Materials Kept Raising What It Expected To Sell
In February management guided its semiconductor systems business to grow more than 20% in calendar 2026. In May that became more than 30%. By August it said the figure would run higher still.
The raises trace to one thing. As 2026 has progressed, customers have found new ways to address the clean room space constraints and have asked for tool deliveries sooner. DRAM revenue, which includes high bandwidth memory packaging, grew 52% year over year in fiscal Q3 2026, and management expects packaging revenue overall to grow more than 70% in calendar 2026.

Its peers did not move like this. Texas Instruments (TXN) returned about 31% over the same year and Microchip Technology (MCHP) about 17%.
But Its Trailing Sales Have Not Caught Up Yet
Company revenue over the trailing twelve months was $30.84 billion, up 7.8% year over year. That is an acceleration from the 5.2% the company averaged over the previous three years, and it is nothing like the move the stock made.
The recent numbers are the ones that moved. Fiscal Q3 2026 revenue was $9.1 billion, up 25% year over year, and management guided fiscal Q4 revenue up 51% year over year, to $10.25 billion at the midpoint. Owning the stock through the past year meant paying for the guided quarter long before the trailing figures could reflect it.
So You Are Paying 11 Times Sales For A Forecast
About $348 billion of market value sits on $30.84 billion of trailing revenue, roughly 11 times sales. At that price the guided quarter is the assumption rather than the upside.
The market has already changed its mind about this once. The shares reached $722.23 inside the past year and now trade at $438.46. The same twelve months hold a 180% gain and a 39% fall from the high, so the forecast and the price have not moved in step.
Follow the forecast rather than the story. Management says the clean room available at its customers will govern how much anyone can ship in calendar 2027, and its own answer to that constraint is a product: a new epitaxy system for DRAM that uses 20% less clean room space than the tools before it. If the raises stop, the trailing figures are what you are holding, which is why the names whose forecasts are still moving up are worth watching as a group.
Enjoy The Move, Then Check What It Did To Your Allocation
A move like this is even better to own than to watch, and it is also how one holding grows into an outsized share of a portfolio. Concentration tends to arrive by accident rather than by decision.
