Micron Technology (NASDAQ:MU) brought in more revenue in a single quarter than it did in its entire previous fiscal year. Sales hit $54.23 billion in fiscal Q4 2026, against $11.32 billion a year earlier, and the full year landed at $133.19 billion versus $37.38 billion in fiscal 2025. Yet the stock trades at under 6 times expected earnings.
Micron makes memory chips, the DRAM and NAND that store and move data for processors. Its customers range from cloud giants building AI data centers to phone, PC, and carmakers, and its profits rise and fall with memory prices. That last part is the catch. Memory has always been a boom-and-bust business, and investors have learned to sell the boom.
The real question isn’t whether Micron’s results are spectacular. They are. It’s whether this cyclical surge makes it a classic fit among 10 High Beta Stocks with Strong Revenue Growth, and whether the boom ends like the others, hinging on something memory makers have rarely had: visibility.
Few Players, Big Pricing Power
Micron’s edge comes from scale and technology in an industry with only a handful of serious producers. Leading-edge memory takes years and enormous sums to build, which keeps new entrants rare. Micron shares that position with a small group that includes South Korean memory giant SK Hynix.
When demand outruns supply, those few producers set the price. The proof shows up in margins. Non-GAAP gross margin (which excludes items like stock-based pay) reached 87.0% in fiscal Q4, up from 45.7% a year earlier.
Data Centers Take Over
The mix shift tells the story. Core Data Center revenue reached $18.00 billion in fiscal Q4, versus $1.58 billion a year earlier, and Cloud Memory added another $16.28 billion. That demand ties Micron tightly to stocks riding AI infrastructure spending; read more about Micron in our list of 11 AI Stocks That Will Go to the Moon.
Momentum hasn’t stalled. Revenue climbed from $41.46 billion in fiscal Q3 to $54.23 billion in Q4, and management guided for $61.5 billion, plus or minus $1.5 billion, in fiscal Q1 2027, with non-GAAP gross margin of about 86.25%.
The more important detail is structural. CEO Sanjay Mehrotra credited Micron’s Strategic Customer Agreements, longer-term arrangements with key customers, with adding confidence that its financial performance can last. In past cycles, memory makers often learned about a downturn only once orders dried up. Commitments like these, if they hold, give Micron something closer to a forecast.
Cash is piling up. Micron generated $62.31 billion in adjusted free cash flow in fiscal 2026 and ended the year with $73.48 billion in cash and investments.
Hasn’t Memory Fooled Investors Before?
Yes, and more than once. Every memory boom invites the same response: producers add capacity, supply catches up, and prices fall faster than expected. Micron is spending heavily itself, with net capital expenditures of $27.37 billion in fiscal 2026, and management has said it’s increasing investment in manufacturing.
If rivals expand just as aggressively, today’s shortage could become tomorrow’s glut, a risk that hangs over fellow memory maker Sandisk as well. And margins near 87% leave little room to improve and plenty of room to fall. The customer agreements soften this risk, but they haven’t yet been tested in a downturn.
Priced for the Bust
At 5.84 times forward earnings, as of October 9, Micron trades far below the sector’s 23.35 multiple and its own 5-year average P/E of 74.18. That historical average is inflated, since Micron’s earnings collapsed in past downturns and sent its P/E soaring. Still, it shows how differently the market treats the stock today. Put plainly, investors are paying about $5.84 for each dollar of expected earnings, and those earnings are expected to grow 133.25% in 2027. A multiple that low on growth that fast says the market expects the profits to vanish. It’s pricing the next bust, not the current boom.
The evidence doesn’t show a rollover yet. Fiscal Q1 2027 guidance calls for non-GAAP EPS of $38.15, plus or minus $1.00, compared with $33.42 in fiscal Q4. Full-year GAAP EPS came in at $74.33, against $75.52 on a non-GAAP basis. Would you need Micron’s boom to last forever to justify the price? Not at this multiple. Even a meaningful drop from peak earnings could leave the shares looking reasonable. The math only breaks if profits shrink dramatically and stay down. Hedge funds seem to agree. In the most recent quarter, 184 funds held Micron, up from 154 in the prior one. Short interest sits at 2.45% of the float, relatively limited bearish positioning for a stock this debated.
Cyclical, but Mispriced?
Micron hasn’t escaped the memory cycle, and it probably never will. But at under 6 times expected earnings, the stock already prices in a severe downturn that its results and guidance don’t show. For investors who can stomach volatility and believe AI demand outlasts the industry’s capacity build, the setup looks unusually favorable. A quarter of falling guidance, or signs that customer agreements are being renegotiated, would mean the market’s skepticism was right.
