MORRISVILLE, N.C. — Telecom gear manufacturer Tekelec will keep its Nasdaq stock listing as it sorts through a review of its finances.

Tekelec (Nasdaq: TKLC) said Thursday before the markets opened that it had won an appeal from Nasdaq regarding its listing. The company faced delisting due to late filing of financial information.

Tekelec also disclosed it would not file the first quarter financial report with the Securities and Exchange Commission by May 10 as required.

A review of financial statements continues, the company said, and it plans to file 2005 reports on or before May 30.
