Summary · why it matters

Micron shares fell 5.7% after TSMC raised its capital expenditure guidance to $60–$64 billion, up from a prior ceiling of $56 billion, despite reporting record profit and raising its full-year 2026 revenue growth outlook to slightly above 40%. The higher capex, along with third-quarter operating margin guidance roughly 70 basis points below consensus and warnings that overseas expansion and 2-nanometer ramp costs would dilute second-half gross margins, shifted investor focus to free cash flow compression and the cost of staying at the leading edge. The selloff compounded a sector-wide decline that began with ASML the day before, as the market priced in the exceptionally high expense of scaling AI manufacturing capacity, forcing a multiple de-rating across semiconductor stocks. Micron remains up 169% year-to-date but is trading 26.5% below its 52-week high of $1,154 from June 2026.
