Management Commentary

“I am pleased with the outstanding financial performance delivered by the Infinera team in the third quarter,” said Tom Fallon, president and chief executive officer. “We achieved new records for quarterly revenue, gross margin and tributary adapter module shipments. The stronger revenue, higher profit margins and ongoing operating expense control resulted in significant income leverage, with a non-GAAP operating income contribution of $18.5 million for the quarter. We believe this operating income contribution, combined with our achievement of 51% gross margin, validates our long-term business model and demonstrates the leverage that is achievable.

“We believe that our continued solid financial performance stems from our customers’ confidence in Infinera’s unique and differentiated PIC-based networks and our expanded product portfolio that provides the end-to-end solutions that they are demanding,” continued Fallon.

The company also noted the following developments in the third quarter and more recently:

• Positive cash from operations of $10.0 million;

• TAM shipments of more than 3,000 units;

• The addition of two new invoiced customers bringing its customer roster to 77;

• The addition of six new ATN metro customers, bringing total ATN customers to 15;

• The launch of new hardware and software products for the company’s DTN and ATN platforms that enable a new end-to-end “Digital OTN” solution; and

• Two important technical demonstrations, including:

• PIC-based 100 Gigabit per second (100G) coherent transmission and reception over a 1,348 kilometer route on an XO Communications nationwide network on a production Infinera line system, and

• 100 Gigabit Ethernet services over Colt’s existing London to Frankfurt Infinera network.
