Acquisition of Tetraphase Pharmaceuticals, Inc.

On June 24, 2020, La Jolla entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Tetraphase, a biopharmaceutical company focused on commercializing its novel tetracycline XERAVA to treat serious and life‑threatening infections, and TTP Merger Sub, Inc., a wholly owned subsidiary of La Jolla. On July 28, 2020, La Jolla completed its acquisition of Tetraphase for $43 million in upfront cash plus potential future cash payments of up to $16 million pursuant to contingent value rights (“CVRs”). The holders of the CVRs are entitled to receive potential future cash payments of up to $16 million in the aggregate upon the achievement of certain net sales of XERAVA in the U.S. as follows: (i) $2.5 million if 2021 XERAVA U.S. net sales are at least $20 million; (ii) $4.5 million if XERAVA U.S. net sales are at least $35 million during any calendar year ending on or prior to December 31, 2024; and (iii) $9 million if XERAVA U.S. net sales are at least $55 million during any calendar year ending on or prior to December 31, 2024. Following the acquisition, Tetraphase became a wholly owned subsidiary of La Jolla. The acquisition of Tetraphase will be accounted for as a business combination pursuant to FASB ASC Topic 805.
