Shares of Catapult Communications Corp. (Nasdaq: CATT) were catapulted higher this morning after the manufacturer of software-based test systems said it now expects higher than anticipated revenues for its fiscal fourth quarter.

For its fourth fiscal quarter ending September 30, the Mountain View, Calif.-based small-cap said it now expects revenues in the range of $9.5 million to $10.5 million. One analyst polled by Thomson Financial anticipates revenues of $9 million for the fourth quarter.

Catapult raised revenue guidance on account of actual order input for the quarter to date and forecast order input for the remainder of the quarter exceeding original expectations.

 “I also expect that our results of operations will be more favorable than our original estimate," Catapult’s CEO Richard Karp said in a statement.

Shares of Catapult gained $0.68, or 10.56%, to $7.12 in morning trading Wednesday.
