EXFO Announces Preliminary Third-Quarter Results

Complete quarterly results will be reported on June 28^th

QUEBEC CITY, June 1, 2012 /CNW Telbec/ - EXFO Inc. (NASDAQ: EXFO) (TSX: EXF) announced today preliminary financial results for the third quarter ended May 31, 2012.

Revenue for the third quarter of fiscal 2012 is expected to be around US$60.0 million compared to EXFO's previous guidance of US$68.0 million to US$73.0 million.

Given the lower-than-anticipated revenue level for the third quarter of 2012, EXFO's gross margin will be negatively affected and IFRS net earnings will end below the company's initial outlook of US$0.01 to US$0.05 per diluted share.

EXFO will report its complete results for the third quarter of fiscal 2012 after the close of markets on June 28, 2012. All financial numbers provided in this news release are preliminary and subject to review.

"Challenging macro-economic conditions, coupled with the tightening of capital spending among network operators during the first half of calendar 2012, have rendered EXFO's end-markets very difficult for the short term," explained Germain Lamonde, EXFO's Chairman, President and CEO. "Europe turned out to be more impacted than expected, the anticipated pick-up of spending in the Americas did not materialize — especially with Tier-I operators — while spending in China has been sluggish. We believe this is not a company-specific issue, but rather a short-term industry spending pattern, since the requirement for wireline and wireless operators to invest in their networks in order to attract growing data revenue remains intact. We see a growing funnel of serious opportunities, but unfortunately they are being delayed and are taking longer to close."

Following the release of its quarterly results on June 28, 2012, EXFO will host a conference call at 5 p.m. Eastern time to review its performance. To listen to the conference call and participate in the question period via telephone on June 28, 2012 at 5 p.m. (Eastern time), dial [phone].

An audio replay will be available one hour after the end of the conference call until 7 p.m. (Eastern time) on July 5, 2012. The replay number is [phone] and the reservation number is 21592376.
