Micron, Red Hat Sales Disappoint

Micron Technology and Red Hat missed Wall Street revenue estimates after the close on Wednesday.

Shares of Micron were unchanged after hours after the company beat earnings estimates by two cents per share with 23-cent earnings. But revenues of $1.26 billion, up 6% year-over-year, missed $1.31 billion forecasts. Average selling prices were flat from the previous quarter, the company said.

Red Hat shares fell 4% after the company reported in-line earnings of 6 cents per share. Sales surged 55% to $50.9 million, but that was less than the $51.5 million that analysts were looking for.

Also after the close, Tibco beat earnings and revenue estimates, while PalmSource fell on a warning.
