The networking gear maker said revenue for the fourth quarter rose 4% to $595.8m from a year ago, beyond the $593m analysts had expected, according to Thomson Financial.

But it was the third consecutive quarter the company has been unable to paint a full fiscal picture. Juniper shares fell more than 8.5% to close at $8.12 on the Nasdaq yesterday. They recovered a couple of cents in after-hours trading.

In December, the company said it had completed its internal review and that some executives and employees had been found to have been improperly granted stock options between mid-1999 and the end of 2003. It said it expects a $900m charge as a result.

The Sunnyvale, California-based company said in December that it would report most of its revised earnings for last year by March 31.
