Blackboard (BBBB), provider of software to the education sector, reported fourth quarter revenue of $63.2 million, with non-GAAP EPS of 25 cents, a bit ahead of the Street at $62.6 million and 24 cents.

But the big story here is much-lower-than-expected guidance for the first quarter and all of 2008. For the first quarter, the company sees revenue of $64 million to $66 million, versus Street expectations of $64.6 million. On a non-GAAP basis, Blackboard expects a loss of 2 cents a share to a profit of one penny. The consensus view had been for a profit of 20 cents.

For the full year, the company sees revenue of $306 million to $314 million, ahead of the Street at $281.4 million. But Blackboard sees EPS of 58-68 cents, far short of the Street view of 96 cents.

In after hours trading, Blackboard fell $2.91, or 8.5%, to $31.30, adding to a loss of 71 cents in the regular session.
