Memory giant Sandisk preps for S&P 100 inclusion amid earnings surge

Sandisk Corporation (SNDK) earned promotion to the S&P 100 ahead of market open, after a Friday rally that sent shares up about 11.9% to 1,740, boosting its market value to roughly $273 billion. The memory-chip maker posted a quarterly revenue surge of 372% to $8.97 billion, with gross margin at 84.6% and data-center revenue more than doubling to $2.98 billion. The company also lifted its share buyback authorization to $15.5 billion and guided for as much as $10.8 billion in revenue next quarter. GuruFocus notes a GF Score of 51/100, signaling growth and strength offset by weaker value and momentum, implying valuation risk if NAND supply catches up.
