iRobot Reports Fourth-Quarter and Full-Year Financial Results
Record Results; Strong 2011 Outlook

BEDFORD, Mass., Feb. 9, 2011 — iRobot Corp. (NASDAQ: IRBT), a leader in delivering robotic technology-based solutions, today announced its financial results for the fourth quarter and full year ended January 1, 2011.

Revenue for the fourth quarter of 2010 increased 12 percent to $114.0 million, compared with $101.7 million for the same quarter one year ago. Revenue for the full year 2010 increased 34 percent to $401.0 million from $298.6 million for the full year 2009. Net income in the fourth quarter of 2010 was $7.0 million, compared with $5.1 million in the fourth quarter of 2009. Net income for the full year 2010 was $25.5 million, compared with $3.3 million for the same period in 2009. Quarterly earnings per share were $0.26, compared with $0.20 in the fourth quarter last year. Full-year earnings per share were $0.96, compared with $0.13 last year. The full-year results include an $0.08 one-time tax benefit reported in the third quarter. Excluding the impact of this one-time benefit, earnings per share for the full year would have been $0.88.

“Our record financial results in 2010 were exceptional on all fronts driven by strong performance in both divisions. Revenue increased 34 percent to $401 million for the full year while Adjusted EBITDA more than doubled to $49 million or 12 percent of revenue,” said Colin Angle, chairman and chief executive officer of iRobot. “EPS of $0.96 for the year, which includes the impact of an $0.08 one-time tax benefit in Q3, was more than seven times greater than our 2009 EPS. Investments and initiatives implemented in 2010 will enable us to continue our profitable growth. In 2011, we expect stronger revenue and earnings growth in the second half of the year due to the timing of G&I orders and year-over-year comparisons with a record-breaking first half of 2010. We anticipate making further progress towards our three-year financial targets, while investing in our future to support our market-leading position.”

Business Highlights

•

Strong demand in overseas markets drove a 70 percent year-over-year increase in full-year 2010 international home robot revenue. International home robot revenue of $151 million comprised 66 percent of total home robot revenue.

•

Driven by shipments of Small Unmanned Ground Vehicles and spares, government & industrial robot revenue grew 29 percent in 2010.

Use of Non-GAAP Financial Measures

In evaluating its business, iRobot considers and uses Adjusted EBITDA as a supplemental measure of its operating performance. The Company defines Adjusted EBITDA as earnings before interest, taxes, depreciation and amortization, merger and acquisition expenses, and non-cash stock compensation. The Company also presents Adjusted EBITDA because it believes it is frequently used by securities analysts, investors and other interested parties as a measure of financial performance.

The term Adjusted EBITDA is not defined under U.S. generally accepted accounting principles, or U.S. GAAP, and is not a measure of operating income, operating performance or liquidity presented in accordance with U.S. GAAP. Adjusted EBITDA has limitations as an analytical tool, and when assessing the Company’s operating performance, investors should not consider Adjusted EBITDA in isolation, or as a substitute for net income (loss) or other consolidated income statement data prepared in accordance with U.S. GAAP. Among other things, Adjusted EBITDA does not reflect the Company’s actual cash expenditures. Other companies may calculate similar measures differently than iRobot, limiting their usefulness as comparative tools. iRobot compensates for these limitations by relying primarily on its GAAP results and using Adjusted EBITDA only supplementally.
