WDC fell nearly 14% and SNDK dropped over 8%, dragging down peers like SK Hynix and Micron. The sector decline was driven by weak next-quarter revenue and EPS forecasts that failed to meet Wall Street's high expectations."

Yesterday, both SanDisk and Western Digital released their fourth-quarter fiscal year 2026 financial results. Although both current-quarter revenue and earnings exceeded market expectations, their guidance for the next quarter failed to meet Wall Street's extremely high expectations, triggering a sharp plunge in stock prices and dragging down the entire U.S. storage and memory sector.

According to the financial report, SanDisk's quarterly revenue was $8.97 billion, beating the expected $8.4 billion; adjusted EPS was $39.25, higher than the expected $34.37. The midpoint of the revenue guidance was $10.55 billion, lower than the $11.16 billion expected by analysts; the midpoint of the EPS guidance was $45.00, also below the expected $45.58.

Western Digital's quarterly revenue reached $3.75 billion, higher than the market expectation of $3.69 billion; adjusted EPS was $3.56, also beating the expected $3.29. The midpoint of the revenue guidance was $4.10 billion, and the midpoint of the EPS guidance was $4.00, meeting most market expectations but failing to reach the extremely high expectations driven by strong market upward revisions.
