Overview

Micron Technology Inc reported fiscal third‑quarter 2026 revenue of $41.46 billion, surpassing Wall Street consensus of $35.69 billion by 16.2%. Earnings per share came in at $25.11, well above the estimated $20.49, a 22.6% upside.

Share‑price reaction

In extended trading, Micron’s stock jumped roughly 12.6% to $1,180.97, up from its regular‑session close of $1,047.20. The earnings beat sparked broad after‑hours gains across the semiconductor sector: SanDisk Corp rose about 10.2% to $2,110, Western Digital Corp also climbed 10.2% to $709.15, Qualcomm Inc surged 12.7% to $222.44, AMD gained 3.4% to $537.51, Intel Corp rose 3.4% to $136.12, and Nvidia edged up 0.5% to $200.08. The iShares Semiconductor ETF (SOXX) advanced 4.1% to $625.94 after ending the regular session down 0.31% at $601.50.

Context and prior volatility

The earnings release came after a turbulent week: on Tuesday, chip stocks retreated from record highs amid AI‑spending concerns, with SanDisk down 12.4% and Western Digital down 8.4%. Micron itself had fallen 13.2% that session and closed the following regular session down 0.44% before the earnings announcement.

Underlying drivers

Micron’s near‑quadrupling year‑over‑year revenue reflects a memory‑supply crunch that has pushed prices sharply higher as AI data‑center construction accelerates. The company’s 52‑week price range spans $103.38 to $1,213.56, and its stock has surged roughly 700% over the prior year. SanDisk’s after‑hours price of $2,110 represents an extraordinary ~3,952% gain from its 52‑week low of $40.10.

Outlook and next steps

Guidance for fiscal fourth quarter was not available at the time of release; analysts will scrutinize forthcoming commentary on memory‑pricing cycles and next‑generation HBM4 pricing. Major banks are expected to revise price targets in the hours following the report, and the earnings release referenced strategic customer agreements that merit further examination.

Market implications

The SOXX ETF’s after‑hours level of $625.94 would, if sustained, move the fund toward its 52‑week high of $655.95, partially reversing the two‑session drawdown. Pre‑market trading on Thursday, June 25, will test whether the after‑hours momentum translates into broader market confidence in the AI‑driven memory chip cycle.
