SanDisk, Western Digital Fall After Earnings

SNDK Goldman TMT on tech weakness SanDisk & Western Digital: Both memory names traded lower after hours despite strong reported quarters, as the issue was not the current print but elevated buy-side expectations going into results.

SanDisk beat on revenue, gross margin and EPS, but 3Q revenue guidance was only slightly below the Street while EPS was broadly in line, triggering some profit-taking after a big prior move; the more supportive takeaway is that SanDisk has locked in multi-year customer supply agreements covering over 50% of FY27 and 65% of FY28 planned bit production at floor pricing, supporting NAND pricing visibility and buybacks.

Western Digital also beat on revenue, margin and EPS and guided 3Q revenue/margins above consensus, but the stock fell because the guide did not reset the bar enough given high HDD pricing and margin expectations, with some concern around softer exabyte growth as the company manages its 40TB ePMR ramp and HAMR qualification; overall, the read-through is a "beat but not enough" night for NAND/HDD, with fundamentals still supportive but expectations very high.
