What Could Go Wrong At Micron From Here?
You own Micron Technology (MU) for its memory boom, and the worry is competition. The boom itself shows in the numbers. Micron’s revenue over the last twelve months was $90.3 billion, against $33.8 billion a year earlier. The company is now valued at about $1.09 trillion, so a dent in those sales would matter to you. Which memory rivals should you watch, and how close are they?
The Rivals To Watch Are Chinese Memory Makers
Two memory makers from China keep appearing in the news. One is YMTC, which a report on Aug 26 called a big threat to Micron. The other is CXMT, which reported its first results as a public company on Aug 28, with booming sales.
Those results showed CXMT gaining from the AI-driven surge that lifted memory prices. CXMT has also claimed an advance in smartphone memory, according to an Aug 31 report. A Sept 18 report said it could expand into flash memory too.
Micron’s own recent gains came mostly from price. DRAM is the chip that brings in most of Micron’s revenue. DRAM’s price rose by a percentage in the low 60s in fiscal Q3 2026. Micron’s DRAM shipments, counted in bits, grew only by a low single-digit percentage. Management said higher pricing was the main driver of that quarter’s record gross margin.
Stifel argued, in a Sept 21 report, that constrained memory supply should support higher prices. Every chip these rivals ship adds to that supply. The question is how much of Micron’s revenue they can reach.
Which Part Of Micron Sits In The Rivals’ Path?
Micron’s most exposed business is its Mobile and Client unit, which sold $11.5 billion in fiscal Q3 2026. That was 28% of Micron’s revenue, so this is a large piece of the company. The unit is exposed because smartphone memory is where CXMT claimed its advance.
The Mobile and Client unit sold $11.9 billion in all of fiscal 2025, up just 1.6%. It now sells nearly that much in a single quarter.
Micron’s long-term contracts give other parts of the business more protection. These take-or-pay agreements bind customers to buy set volumes for several years. Management said the agreements signed so far are with data center and auto customers.
The agreements cover roughly 20% of Micron’s DRAM volume. They also cover a third of its NAND volume, Micron’s other chip line. Mobile is not one of the named markets, so the Mobile and Client unit has less of that protection.
Micron’s price looks very different depending on the measure. The stock trades at 12.0 times its sales, against 3.1 for the S&P 500. Micron trades at 21.4 times its last twelve months’ earnings, against 22.4 for the index. Those earnings are based on an operating margin of 66%, the share of sales left as operating profit.
That margin is the highest in ten years. Over the past three years it averaged 11.2%. The price appears to assume that margin holds, so it helps to know how far the shares have fallen before.
How Far Could Your Micron Shares Drop?
In their two deepest recent falls, Micron shares dropped about twice as far as the S&P 500. During the 2022 inflation shock, they fell 49% from peak to trough, against 24% for the index. During the 2025 tariff shock, they fell 38%, against 19%.
A $10,000 holding at the 2022 peak was worth about $5,100 at the trough. Those falls came from market-wide shocks, not from a rival. Still, they show how far the shares can move in a bad stretch.
The threat from Chinese rivals looks real but slow. Management said on the fiscal Q3 2026 call that it expects tight supply to last beyond calendar 2027. It also said new chip plants around the world take a long time to build. That limits how fast any rival can add output. The worry stays small only while memory supply stays tight longer than the Chinese rivals need to catch up.
Micron reports fiscal Q4 2026 results on Sept 30. Mobile and Client revenue above its fiscal Q3 level would be a good sign. A fall from that level would be worth a closer look, since price moves also drive this revenue. Management repeating that supply stays tight beyond calendar 2027 would ease the worry.
