iRobot Announces Preliminary Unaudited Fourth Quarter and
Full Year 2007 Results

Revenue in line with expectations; Significant income tax benefits partially offset by costs associated with lawsuit settlement result in increased EPS compared to prior year

BURLINGTON, Mass., Jan. 22, 2008 – iRobot Corp. (Nasdaq: IRBT) today announced that it anticipates revenue for the fourth quarter of 2007 in the range of $98 million to $100 million and revenue for the full year 2007 in the range of $248 million to $250 million.

“I am extremely pleased to report that we anticipate fourth quarter and full year revenue to be in line with our expectations following a successful holiday season for our new iRobot^® Roomba^® 500 Series robot, despite widely reported weakness in general retail. The company’s Government & Industrial Robots business also made a strong contribution to the quarter,” said Colin Angle, chief executive officer of iRobot. “There also were two one-time events in the fourth quarter that impact fourth quarter and full year profitability: an anticipated income tax valuation reversal of at least $8 million and estimated litigation and settlement costs of approximately $1.6 million associated with the resolution of a lawsuit against Robotics FX that we announced last month,” he added.

“On a GAAP basis, we are expecting pre-tax profit between $12.1 million and $12.6 million for the fourth quarter and a pre-tax profit for the full year between $500,000 and $1 million. These results reflect the litigation settlement costs and lower than expected gross margins. Excluding the full year litigation and settlement costs of approximately $2.3 million, 2007 pro forma pre-tax profit is expected to be approximately $3 million. GAAP earnings per share are expected to be between $0.79 and $0.81 in the fourth quarter and between $0.33 and $0.35 for the full year, including the anticipated income tax valuation reversal,” Angle said.

“Based upon the company’s profits since December 31, 2004, and its expected annual profitability in 2008 and future years, at least $8 million of the deferred tax asset valuation allowance will be reversed effective December 29, 2007,” said Geoff Clear, chief financial officer of iRobot. “Reversal of the valuation allowance will be a discrete event and will result in a significant non-cash income tax benefit in the fourth quarter of 2007,” Clear added.

Angle continued, “Our results demonstrate the strength of our business, and we exited the year with excellent momentum and visibility. We are optimistic about strong revenue growth and

improved profitability across the company in 2008. The details of our expectations will be provided during our fourth quarter earnings call in February,” he said.
