Micron Technologies (MU) reported a beat on the top and bottom lines in the fiscal fourth quarter afterhours on Wednesday.

Micron earned $33.42 in adjusted EPS on $54.23 billion in revenue in Q4. Those figures easily surpassed Wall Street's consensus of $31.82 in adjusted EPS (+$1.60) and $51.5 billion in revenue (+$2.73 billion). That sales figure surged 379% YoY, even higher than the annual growth rate in the prior quarter.

Gross margin, possibly the most important figure in the release, arrived at 86.8%, above the company's 86.0% projection and the previous quarter's 84.6% figure. That led the operating margin to rise by three-tenths of a percent to 80.7%.

Micron earned $37.7 billion in the quarter, about 12 times the $3.2 billion earned in the same quarter a year ago. That figure was also about $9.5 billion higher than the third fiscal quarter that ended in August.
