Vol. 4, No. 16, September 2006
UPDATED November 9, 2006:
On page 34, in the capsule description of Infinera Corp., we wrote: "Infinera reported revenue of $25 million in the fourth quarter of 2005 and estimates 2006 full-year revenue will be $75 million on sales of $90-100 million. Throughout the year the company has been rumored to be planning a large initial public offering (IPO) in the $1 billion range, but in July it announced another $110 million in venture funding, which suggests that an IPO is not imminent. The latest round brings Infinera's total venture funding since inception to $315 million."
This should have read (alterations in italics): "Heavy Reading estimates that Infinera had revenues of $25 million in the fourth quarter of 2005 and $75 million to $100 million for the full year 2006. Throughout the year the company has been rumored to be planning a large initial public offering (IPO) in the $1 billion range, but in July industry publications cited SEC filings showing that it raised another $110 million in venture funding, which suggests that an IPO is not imminent. The latest round brings Infinera's total venture funding since inception to $315 million. Infinera declined to comment on any financial matters."
