Red Mountain Capital Partners LLC (“Red Mountain” or “we”), an investment management firm owning approximately 6.2% of the outstanding shares of iRobot Corporation (“iRobot” or the “Company”) (Nasdaq:IRBT), today released a letter to fellow shareholders, available at www.irobotproxycontest.com, in connection with its campaign to elect two highly qualified individuals, Lawrence S. Peiros and Willem Mesdag, to the Board of Directors of the Company (the “Board”) at the 2016 annual meeting of shareholders of iRobot.

In its letter, Red Mountain states that it is deeply concerned with the prolonged underperformance of iRobot’s share price. Red Mountain believes that the main reason for iRobot’s underperformance has been the incumbent Board’s poor oversight of management’s capital allocation. While Red Mountain has already been a catalyst for positive change at the Company, it believes that much more needs to be done.

Red Mountain is one of iRobot’s largest shareholders and its interests are aligned with the Company’s other shareholders. Red Mountain strongly recommends that shareholders vote on the GREEN proxy card to elect its experienced director nominees, Lawrence S. Peiros and Willem Mesdag, at iRobot’s upcoming annual meeting of shareholders to be held on May 25, 2016.

Shareholders who have questions about Red Mountain’s case for change, or require assistance in voting their GREEN proxy card, are encouraged to visit www.irobotproxycontest.com or contact Richard Grubaugh at D.F. KING & CO. at 212-493-6950 or rgrubaugh@dfking.com
