GILEAD SCIENCES, INC. 8-K/A Report, Acquisition Completed (Feb 1, 2007)

Filed February 1, 2007For Securities:GILD

Summary

This Form 8-K/A filing by Gilead Sciences, Inc. (GILD) provides updated financial information related to its acquisition of Myogen, Inc. The primary purpose is to file the historical financial statements of Myogen and the unaudited pro forma combined financial information of Gilead and Myogen, which were initially omitted from the original 8-K filing. This amendment allows investors to see the financial impact of the acquisition as if it had occurred at earlier dates. The acquisition, completed on November 17, 2006, was a cash tender offer for all outstanding Myogen shares, with remaining shares converted to $52.50 cash. The report details the preliminary purchase price allocation, including significant amounts allocated to goodwill and purchased in-process research and development (IPR&D). The IPR&D allocation is largely attributed to Myogen's late-stage product candidates, ambrisentan for pulmonary arterial hypertension and darusentan for resistant hypertension.

Frequently Asked Questions

This filing is an amendment to a previous Form 8-K. Its main purpose is to provide the required historical financial statements of Myogen, Inc. and the unaudited pro forma combined financial information for Gilead Sciences and Myogen, which were not included in the original filing upon completion of the acquisition.

The total purchase price for Myogen was approximately $2.44 billion. This included $2.34 billion in cash paid at closing, the fair value of vested stock options assumed ($85.5 million), estimated direct transaction costs ($13.1 million), and employee-related severance costs ($4.0 million). A substantial $2.06 billion was allocated to purchased in-process research and development (IPR&D), with the remainder allocated to goodwill ($107.9 million) and other net assets.

The acquisition brought in two key product candidates: ambrisentan, an endothelin receptor antagonist for pulmonary arterial hypertension (which had completed Phase 3 trials and for which an NDA was filed), and darusentan, another endothelin receptor antagonist for resistant hypertension (in Phase 3 clinical development).

The $2.06 billion allocated to IPR&D represents the estimated fair value of Myogen's incomplete research and development programs at the time of acquisition. As per accounting standards, this amount was expensed immediately upon acquisition. The significant allocation highlights the perceived future value and potential of ambrisentan and darusentan, though it also underscores the inherent risks and uncertainties in drug development and regulatory approval.
