        <footnote id="F1">On September 13, 2018, the reporting person filed a Form 4 reporting the sale of 14,162 shares of common stock. The previously reported transaction was subsequently broken and unwound by the broker and, therefore, did not in fact occur for the reporting person's account. As of September 12, 2018, the reporting person beneficially owned 36,209 shares of common stock of Agios Pharmaceuticals, Inc.</footnote>
