Micron Technology MU recently joined the elite club of trillion-dollar companies after its stock skyrocketed more than 900% in one year. The company is benefiting from a tremendous memory pricing cycle, thanks to demand for artificial intelligence infrastructure. Tight memory supply is driving ridiculous pricing growth, boosting revenue and profitability, and we expect supply constraints to keep prices rising into 2027. But the key question is how long this cycle lasts and how high it goes. We expect a peak between 2027 and 2028 and a precipitous downcycle thereafter, in 2029. Based on our forecasts, Micron’s stock is outrageously overpriced: We think it is worth $455 per share, but it trades at more than twice that today. Micron was one of Morningstar Chief US Market Strategist Dave Sekera’s five stocks to sell on a recent episode of The Morning Filter podcast.

Micron is the fifth-largest chipmaker in the world, with a third-place market share in DRAM chips and a fifth-place market share in NAND flash chips. In the medium term, we see artificial intelligence driving a strong and enduring upcycle for the company. Micron supplies high-bandwidth memory chips into AI processors from the likes of Nvidia. We credit AI investments for Micron’s strong growth in fiscal 2025, and they are a significant driver of our five-year forecast. We believe high-bandwidth memory will continue to rise as a share of Micron’s total shipments and revenue, supporting growth and margins. We also like Micron’s shareholder distributions and view its balance sheet as good for a cyclical memory chipmaker.

Key Morningstar metrics for Micron

  • Fair Value Estimate: $455
  • Star Rating: 1 Star
  • Economic Moat Rating: None
  • Uncertainty Rating: High

Economic Moat Rating

We do not believe Micron has an economic moat. The company operates in a highly capital-intensive industry, and it doesn’t earn good enough profit margins through the course of a cycle to give us confidence in enduring economic profits. We view DRAM and NAND as commodity-like products prone to market supply/demand dynamics and steady pricing erosion that reduces industry profitability. While we see better margins in DRAM, which has consolidated to three primary players (versus six in NAND), we still don’t see high enough returns on invested capital over the cycle to result in an economic moat.

Fair Value estimate for Micron Stock

Our $455 fair value estimate implies a fiscal 2026 adjusted price/earnings multiple of 7 times and an enterprise value/sales multiple of 4 times. We expect AI to drive 200% revenue growth in fiscal 2026, with another strong year in fiscal 2027. Thereafter, we model pricing to normalize, with growth slowing and peaking in 2028. In 2029, we forecast a harsh downcycle, with revenue falling nearly 50%. In the medium term, we see gross margin reaching 80% thanks to high pricing. In the long term, we expect gross margins of 40%-50%. In the current upcycle, we forecast non-GAAP operating margin rising to the low 80s. At midcycle, we think Micron can earn non-GAAP operating margins close to 40%.

Risk and uncertainty

Micron’s largest risk comes from its high cyclicality, in our view. Memory chipmakers are susceptible to fluctuations in market supply and demand for commodity-like chips, and periods of oversupply can slash prices. Micron has a high fixed cost base, so weak pricing can have an outsize effect on profitability. The company also bears risk from its China exposure, which sits at roughly 25% of sales. If Micron is left out of the consolidation in the NAND market, it could see a gap in scale relative to peers. Roughly half of Micron’s sales come from 10 customers; losing one or more of these could have a negative impact on results.

Micron bulls say

  • When memory markets are in an upswing and demand is strong, Micron’s sales growth and profitability can be impressive.
  • Micron is benefiting from immense growth in high-bandwidth memory revenue due to high investments in AI infrastructure. This boosts its growth and margin profile.
  • We like Micron’s shareholder returns and view its balance sheet as strong for a cyclical company.

Micron bears say

  • Micron has a high fixed cost base that leaves it vulnerable to underutilization charges and major profit compression when memory markets enter a downturn.
  • We see DRAM and NAND as commodity-like products and foresee little ability for Micron to build durable differentiation from its competitors.
  • Micron is extremely sensitive to memory pricing. Weaker pricing growth in an upcycle, or a more volatile downcycle, can greatly depress its results and valuation.
