Micron Warns Memory Shortage Will Persist Through 2028 Despite Record Earnings

Key points

• Micron CEO Sanjay Mehrotra confirmed that demand for memory will exceed supply for the next two years, with 75% of 2027 output already contracted.
• Samsung executive Kim Taewoo noted that high-bandwidth memory (HBM) will consume nearly 30% of DRAM wafer capacity in 2027, up from 20% in 2026, limiting consumer RAM availability.
• Micron reported exceptional margins of 87% in the last quarter, but shares fell 1.5% on Friday due to concerns about the cyclical nature of the chip industry and potential margin pressure.
• BNP Paribas analyst Karl Ackerman maintained an 'Outperform' rating with a $1,700 price target but warned that potential changes in Nvidia's GPU specifications could alleviate supply tightness.
• Micron has ceased selling consumer RAM, prioritizing high-bandwidth memory for AI and servers, which has driven up prices for prebuilt PCs and other consumer electronics.

Background

Recent reports indicate a structural memory squeeze driven by AI demand, with SK Hynix warning that supply-demand balance may not return until 2030. Micron has secured approximately $100 billion in guaranteed revenue from strategic customer agreements, positioning it as a key beneficiary of the AI memory cycle despite lower valuations compared to Nvidia.

How outlets are covering it

Ars Technica emphasizes the physical constraints of the shortage, citing Micron and Samsung executives who predict supply tightness will persist through 2028 due to manufacturing ramp-up times and HBM demand. Barron's focuses on the financial implications, highlighting investor anxiety over Micron's record 87% margins and the cyclical risks of the chip industry, despite strong earnings. While both acknowledge the tight supply, Ars Technica views it as a structural issue affecting consumer prices, whereas Barron's frames it as a potential peak in the cycle that could lead to margin compression.

Why it matters

The prolonged memory shortage impacts costs across the tech sector, from AI servers to consumer electronics. Micron's dominance in high-bandwidth memory makes it a critical indicator of AI infrastructure health, while its stock performance reflects broader market sentiment on the sustainability of the AI boom.

What to watch

Investors will monitor Micron's ability to maintain margins as new manufacturing capacity comes online in 2028. Analysts will watch for signs of demand softening or changes in Nvidia's GPU specifications that could alleviate supply tightness. Consumer electronics prices may continue to rise as memory costs remain elevated.
