LINTHICUM, Md. -- Ciena® Corporation (NASDAQ: CIEN), the network specialist, today announced results for its fiscal third quarter ended July 31, 2007. Revenue for the third quarter totaled $205.0 million, representing a 5.9% sequential increase from fiscal second quarter revenue of $193.5 million, and an increase of 34.4% over the same period a year ago when the Company reported sales of $152.5 million. For the nine months ended July 31, 2007, Ciena reported revenue of $563.6 million, representing an increase of 39.5% over revenue of $404.1 million for the same nine-month year-ago period.

On the basis of generally accepted accounting principles (GAAP), Ciena's net income for the fiscal third quarter 2007 was $28.3 million, or $0.29 per diluted share. This represents a 117.6% sequential increase from fiscal second quarter GAAP net income of $13.0 million, and compares with a reported GAAP net loss of $4.3 million, or a loss of $0.05 per share, for the same period a year ago. For the nine-month period ended July 31, 2007, Ciena's reported GAAP net income was $52.4 million, or $0.57 per diluted share. This compares to a GAAP net loss of $12.5 million, or $0.15 per share, for the same nine-month year-ago period. Note that calculating diluted earnings per share for the fiscal third quarter 2007 and for the nine-month period ended July 31, 2007 requires that the interest expense of $1.3 million and $2.2 million for the periods respectively, associated with the Company's 0.25% and 0.875% convertible senior notes, be added to GAAP net income in order to arrive at the numerator for the earnings per share calculation.

"Consistent execution of our network specialist strategy has enabled Ciena to benefit from two significant industry trends: the demand for increasing network capacity and the transition to Ethernet/IP-based network infrastructures," said Gary Smith, Ciena president and CEO. "At the same time, we continue to drive actions resulting in improved financial performance across the Company."
