Memory chip makers post record profit growth but shares slump amid AI spending concerns

Micron Technology, SanDisk and SK Hynix reported extraordinary revenue increases in fiscal 2026, with Micron posting $133.2 billion, SanDisk $11.03 billion and SK Hynix 104.62 trillion won, all far above prior‑year levels. Despite the earnings surge, their stocks fell 23% to 60% below 2026 peaks as investors worry about the durability of AI‑driven demand and possible oversupply. Analysts kept buy ratings and high price targets, but market sentiment turned negative after weaker outlooks from other tech giants.

The sharp disconnect means investors may continue to discount memory makers despite strong cash flow, keeping valuations below recent highs (the company notes shares are 23%‑60% below 2026 peaks). Analysts maintain bullish price targets, so the gap could present a valuation opportunity if demand holds.
