Oclaro Announces Preliminary 2013 First Fiscal Quarter Revenues

SAN JOSE, Calif., – October 5, 2012 – Oclaro, Inc. (NASDAQ: OCLR), a provider of optical components, modules and subsystems, today announced preliminary revenues of approximately $149 million in its first fiscal quarter ending September 29, 2012, compared to the low end of its guidance of $154 million, previously issued on July 31, 2012. On July 23, 2012 the Oclaro/Opnext merger closed. The first fiscal quarter includes revenues from the former Opnext subsequent to the close of the merger.

Certain principal factors that contributed to the lower than expected revenues in the first quarter of fiscal 2013 include:

“We are disappointed that the revenues for the first quarter of our 2013 fiscal year are below guidance,” said Alain Couder, Chairman and CEO of Oclaro. “Following the merger, our integration activities are on track to execute our synergies, and our customer relationships are strong. We expect these factors to strengthen our future performance and expect revenues to be up in the December quarter.”

Oclaro cautions that its anticipated revenue results are preliminary and based on the best information currently available, and are subject to completion of the financial statements for the first quarter of fiscal 2013.
