Forward-Looking Statements

This Form 8-K and the exhibit attached hereto contain forward-looking statements of AVEO Pharmaceuticals, Inc. (“AVEO” or the “Company”) that involve substantial risks and uncertainties. All statements, other than statements of historical facts, contained in this Form 8-K and the exhibit attached hereto, are forward-looking statements. The words “anticipate,” “believe,” “estimate,” “expect,” “intend,” “may,” “plan,” “predict,” “project,” “target,” “potential,” “will,” “would,” “could,” “should,” “continue,” “contemplate,” or the negative of these terms or other similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain these identifying words. These forward-looking statements include, among others, statements about: the Company’s planned development, commercialization and manufacturing plans, timelines and strategies for tivozanib; the potential therapeutic advantages and benefits of tivozanib and the Company’s other product candidates; the timing and results of the Company’s ongoing and planned preclinical studies and clinical trials; the potential benefits of the Company’s strategic partnership agreements, its ability to achieve additional payments under these arrangements and its ability to enter into additional arrangements; the Company’s plans to leverage its Human Response Platform^™ to inform clinical development; its intellectual property position and strategies; the expected RCC market and potential of tivozanib to obtain regulatory approval and enter this market; the Company’s anticipated plans for success in the oncology markets; the anticipated dates for the FDA’s ODAC meeting to review the Company’s NDA for tivozanib and the completion of the FDA’s review of the NDA; and the Company having sufficient capital to fund its operations into the second quarter of 2014 and the Company’s estimates for its 2013 expected year-end cash balance.

Actual results or events could differ materially from the plans, intentions and expectations disclosed in the forward-looking statements that the Company makes due to a number of important factors, including risks and uncertainties inherent in pharmaceutical research and development, such as those related to: the Company’s ability to successfully develop, test and gain approval of its product candidates, including regulatory approval of tivozanib to treat advanced RCC; the Company’s ability to obtain, maintain and enforce intellectual property rights; competition; the Company’s dependence on its alliance partners and other third parties; the Company’s ability to obtain necessary financing; adverse economic conditions; and other risk factors discussed in the “Risk Factors” and elsewhere in its Current Report on Form 8-K filed with the Securities and Exchange Commission (the “SEC”) on January 16, 2013 and in its other filings with the SEC. The forward-looking statements in this Form 8-K and the exhibit attached hereto represent the Company’s views as of the date of this Form 8-K. The Company anticipates that subsequent events and development will cause its views to change. However, while it may elect to update these forward-looking statements at some point in the future, it has no current intention of doing so except to the extent required by applicable law. You should, therefore, not rely on these forward-looking statements as representing the Company’s views as of any date subsequent to the date of this Form 8-K.
