Dear Fellow Stockholder:

We previously sent you proxy materials for the virtual special meeting of stockholders of iRobot Corporation (the “Company”) in connection with our proposed acquisition by Amazon.com, Inc. (“Amazon”), to be held on October 17, 2022 at 8:30 a.m. ET. Your Board of Directors unanimously recommends voting FOR all agenda items.

Because Proposal 1, to approve and adopt the merger agreement with Amazon, requires the affirmative vote of a majority of the outstanding shares, your vote is very important, regardless of the number of shares that you own.

To ensure that your shares are represented at the meeting, please vote TODAY by telephone, via the Internet, or by signing, dating and returning the hard-copy proxy card or voting instruction form. If you received this letter by email you may also vote by simply clicking the “VOTE NOW” button in the accompanying email.

Thank you for your support,

Colin M. Angle

Chairman of the iRobot Board of Directors and

Chief Executive Officer

Cautionary Statement Regarding Forward-Looking Statements

This communication contains “forward-looking statements” within the meaning of the federal securities laws, including Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Exchange Act. These forward-looking statements are based on the Company’s current expectations, estimates and projections about the expected date of closing of the proposed transaction and the potential benefits thereof, its business and industry, management’s beliefs and certain assumptions made by the Company and Amazon, all of which are subject to change. In this context, forward-looking statements often address expected future business and financial performance and financial condition, and often contain words such as “expect,” “anticipate,” “intend,” “plan,” “believe,” “could,” “seek,” “see,” “will,” “may,” “would,” “might,” “potentially,” “estimate,” “continue,” “expect,” “target,” similar expressions or the negatives of these words or other comparable terminology that convey uncertainty of future events or outcomes. All forward-looking statements by their nature address matters that involve risks and uncertainties, many of which are beyond our control, and are not guarantees of future results, such as statements about the consummation of the proposed transaction and the anticipated benefits thereof. These and other forward-looking statements, including the failure to consummate the proposed transaction or to make or take any filing or other action required to consummate the transaction on a timely matter or at all, are not guarantees of future results and are subject to risks, uncertainties and assumptions that could cause actual results to differ materially from those expressed in any forward-looking statements. Accordingly, there are or will be important factors that could cause actual results to differ materially from those indicated in such statements and, therefore, you should not place undue reliance on any such statements and caution must be exercised in relying on forward-looking statements. Important risk factors that may cause such a difference include, but are not limited to: (i) the ability of the parties to consummate the proposed transaction in a timely manner or at all; (ii) the satisfaction (or waiver) of closing conditions to the consummation of the proposed transaction, including with respect to the approval of the Company’s stockholders; (iii) potential delays in consummating the proposed transaction; (iv) the ability of the Company to timely and successfully achieve the anticipated benefits of the proposed transaction; (v) the occurrence of any event, change or other circumstance or condition that could give rise to the termination of the merger agreement; (vi) the impact of the COVID-19 pandemic and the current conflict between the Russian Federation and Ukraine on the Company’s business and general economic conditions; (vii) the Company’s ability to implement its business strategy; (viii) significant transaction costs associated with the proposed transaction; (ix) potential litigation relating to the proposed transaction; (x) the risk that disruptions from the proposed transaction will harm the Company’s business, including current plans and operations; (xi) the ability of the Company to retain and hire key personnel; (xii) potential adverse reactions or changes to business relationships resulting from the announcement or completion of the proposed transaction; (xiii) legislative, regulatory and economic developments affecting the Company’s business; (xiv) general economic and market developments and conditions; (xv) the evolving legal, regulatory and tax regimes under which the Company operates; (xvi) potential business uncertainty, including changes to existing business relationships, during the pendency of the merger that could affect the Company’s financial performance; (xvii) restrictions during the pendency of the proposed transaction that may impact the Company’s ability to pursue certain business opportunities or strategic transactions; and (xviii) unpredictability and severity of catastrophic events, including, but not limited to, acts of terrorism or outbreak of war or hostilities, as well as the Company’s response to any of the aforementioned factors. These risks, as well as other risks associated with the

proposed transaction, are fully discussed in the Proxy Statement filed with the SEC in connection with the proposed transaction. Additional risks and uncertainties that could cause actual outcomes and results to differ materially from those contemplated by the forward-looking statements are included under the caption “Risk Factors” in the Company’s most recent annual and quarterly reports filed with the SEC and any subsequent reports on Form 10-K, Form 10-Q or Form 8-K filed from time to time and available at www.sec.gov. While the list of factors presented here is, and the list of factors presented in the Proxy Statement are, considered representative, no such list should be considered to be a complete statement of all potential risks and uncertainties. Unlisted factors may present significant additional obstacles to the realization of forward-looking statements. Consequences of material differences in results as compared with those anticipated in the forward-looking statements could include, among other things, business disruption, operational problems, financial loss, legal liability and similar risks, any of which could have a material adverse effect on the Company’s financial condition, results of operations, or liquidity. The forward-looking statements included herein are made only as of the date hereof. The Company does not assume any obligation to publicly provide revisions or updates to any forward-looking statements, whether as a result of new information, future developments or otherwise, should circumstances change, except as otherwise required by securities and other applicable laws.
