Forward-Looking Statements This news release contains certain forward-looking statements by Ligand that involve risks and uncertainties and reflect Ligand’s judgment as of the date of this release. Actual events or results may differ from Ligand’s expectations. For example, we may not be profitable or cash-flow positive before the end of 2012, we may not receive expected revenue from material sales of Captisol, we may not be able to effectively integrate CyDex’s business into our current business, expected royalties on partnered products or from research and development milestones may not be received, and we and our partners may not be able to timely or successfully advance any product(s) in Ligand’s internal or partnered pipeline. In addition, there can be no assurance that Ligand will achieve its guidance for 2012 or beyond, that Ligand will deliver strong cash flow over the long-term, that Ligand will realize the expected benefits of the acquisition of CyDex, that Ligand’s 2012 revenues will be at the levels or be broken down as currently anticipated or that Captisol sales will be sufficiently strong, that Ligand will be able to create future revenues and cash flows by developing innovative therapeutics, that results of any clinical study will be timely, favorable or confirmed by later studies, that products under development by Ligand or its partners will receive regulatory approval, or that there will be a market for the product(s) if successfully developed and approved. Also, Ligand and its partners may experience delays in the commencement, enrollment, completion or analysis of clinical testing for its product candidates, or significant issues regarding the adequacy of its clinical trial designs or the execution of its clinical trials, which could result in increased costs and delays, or limit Ligand’s ability to obtain regulatory approval. Further, unexpected adverse side effects or inadequate therapeutic efficacy of Ligand’s product(s) could delay or prevent regulatory approval or commercialization. Ligand may also have indemnification obligations to King Pharmaceuticals or Eisai in connection with the sales of the Avinza and oncology product lines. In addition, Ligand may not be able to successfully implement its strategic growth plan and continue the development of its proprietary programs. The failure to meet expectations with respect to any of the foregoing matters may reduce Ligand’s stock price.
