“We are pleased to report that increased demand for a broad range of our communication product offerings and robust sales of our PCI Express^® devices enabled us to post better-than-expected results in our fiscal fourth quarter, despite anticipated weakness in our computing and consumer end markets,” said Ted Tewksbury, president and CEO of IDT. “Strength in our core businesses, increased traction with new products, and tight cost controls allowed us to weather broader economic weakness in fiscal 2008. We are confident that the strong design activity we are experiencing across our industry-leading serial switching, communication clocks, and digital display product lines, combined with improvement in our core businesses, places us in a solid position to deliver increased stockholder value in fiscal 2009. I am excited to be a part of this dynamic organization and believe the best is yet to come for IDT.”

Company highlights for the quarter include:
