Aug 17 (Reuters) - JDS Uniphase Corp forecast weak first-quarter revenue on macro-economic challenges and inventory corrections but said booking trends were encouraging.
Shares of the company, which provides broadband and optical communication components, fell much as 16 percent to $9.80 in after-market trading on Wednesday, before recouping the losses.
The company expects first-quarter non-GAAP net revenue of $400-$425 million and operating margin to be 7.5-9.5 percent.
Analysts on average were expecting revenue of $470.3 million for the first quarter, according to Thomson Reuters I/B/E/S.
“General economic conditions and uncertainties, inventory corrections by our optical communications customers, and seasonally weak September quarter for our Comcast business segment are causing short-term volatility for us,” said Chief Executive Tom Waechter on a conference call.
“We do believe it’s a near-term issue as we see improving booking trend for our optical components business across the customer base and it is encouraging,” Waechter said.
For the fourth quarter, earnings rose to $9.3 million, or 4 cents per share, from $1.5 million, or 1 cent per share, a year ago.
The company, which competes with Finisar Corp , Oclaro Inc and Opnext Inc , said adjusted earnings came in at 23 cents a share.
Non-GAAP revenue rose 4 percent to $472.3 million.
Analysts on average had expected earnings of 23 cents a share, on revenue of $466.3 million.
