Why Sandisk Stock Dropped This Morning

SNDK shares dropped 7.5% following reports that the Trump Administration will allow AAPL to source memory chips from Chinese manufacturers CXMT and YMTC. The authorization currently applies only to chips destined for Apple products sold within China, but the move opens the door for two well-capitalized rivals to compete directly with SanDisk's NAND and high-bandwidth flash memory business.

Both CXMT and YMTC have raised billions in funding to expand production capacity. The Chinese suppliers now have a validated channel into one of the world's largest hardware ecosystems, even if geographically limited for now. The approval signals a targeted carve-out in U.S.-China tech policy that could shift share in the memory chip market.

SanDisk's 7.5% decline reflects investor concern that the exemption may widen over time or set a precedent for other U.S. companies to source from subsidized Chinese memory manufacturers.
