SanDisk(SNDK 0.00%↑) delivered a set of financial results that would be considered explosive in any industry.

Q4 revenue was about $9 billion, up 372% year-over-year, beating the market expectation of $8.394 billion. Adjusted EPS came in at $39.25, roughly 14% higher than the expected $34.45. Gross margin hit 84.6%, more than triple the 26.4% from a year ago.

Full-year revenue reached $20.248 billion, up 175% year-over-year. GAAP net income was $11.433 billion, compared with a loss of $1.641 billion in the prior year. Data center revenue for the full year grew 437% to $5.153 billion.

The board also approved a new $14 billion share repurchase program, bringing the total remaining authorization to $15.5 billion.

Every single metric is at a crushing level.
