WATERTOWN, Mass.--(BUSINESS WIRE)--May 29, 2020--
Tetraphase Pharmaceuticals, Inc. (Nasdaq:TTPH), a biopharmaceutical company focused on commercializing its novel tetracycline XERAVATM (eravacycline for injection) to treat serious and life-threatening infections, today announced that it has entered into a second amendment to the Agreement and Plan of Merger, dated March 15, 2020, asamended on May 27, 2020, to which the Company is a party with AcelRx Pharmaceuticals, Inc. (“AcelRx”) and its merger subsidiary (the “Merger Agreement”), to increase the consideration payable to Tetraphase shareholders.
Under the amended Merger Agreement, Tetraphase stockholders will receive, for each share of Tetraphase common stock, (1) $0.5872 in cash and 0.7409 of a share of AcelRx common stock, representing approximately $1.70 in upfront per share value, based on the closing price of AcelRx’s common stock as of the close of trading on May 28, 2020, in each case subject to downward adjustment in the event that the Company’s closing net cash is less than $5.0 million, and (2) one contingent value right (“CVR”), which would entitle the holders to receive potential aggregate payments of up to $16.0 million in cash upon the achievement of certain future XERAVA™ net sales milestones starting in 2021. Under the terms of the Merger Agreement prior to the second amendment, upon the consummation of the transaction, Tetraphase stockholders were entitled to receive for each share of Tetraphase common stock, (1) $0.2434 in cash and 0.7217 of a share of AcelRx common stock, in each case subject to downward adjustment in the event that the Company’s closing net cash is less than $5.0 million, and (2) one CVR, which would have entitled the holders to receive potential aggregate payments of up to $14.5 million in cash or AcelRx stock, at AcelRx’s option upon the achievement of future XERAVA™ net sales milestones starting in 2021.
AcelRx proposed the second amendment to the Merger Agreement in response to a proposal from Melinta Therapeutics, Inc. (“Melinta”), on May 27, 2020, to acquire Tetraphase for $34.0 million in cash (or $1.52 per share of Tetraphase common stock), plus an additional $16.0 million in cash potentially payable under CVRs upon the achievement of certain future XERAVA™ net sales milestones starting in 2021.
The boards of directors of Tetraphase and AcelRx have each approved the second amendment to the Merger Agreement. Tetraphase’s board of directors has determined that as a result of the second amendment to the Merger Agreement with AcelRx, Melinta’s proposal is not superior and recommends the Merger Agreement, as amended by the amendment, to its stockholders.
Based on the closing price of AcelRx stock on May 28, 2020, the total upfront consideration to be received by Tetraphase equityholders is valued at approximately $37.0 million, with approximately $18.7 million of this amount allocated to the Company’s outstanding common stock warrants. In the merger, Tetraphase stockholders would also be entitled to receive, for each share of Tetraphase common stock, one non-tradeable CVR, the holders of which will be entitled to receive potential payments of up to an additional $16.0 million in cash in the aggregate upon the achievement of net sales of XERAVA™ in the United States, payable as follows: (i) $2.5 million upon annual net sales of $20.0 million during 2021, (ii) $4.5 million upon annual net sales of $35.0 million during any year ending on or before December 31, 2024 and (iii) $9.0 million upon annual net sales of $55.0 million during any year ending on or before December 31, 2024.
The special meeting of Tetraphase’s stockholders to approve the pending transaction is scheduled for June 8, 2020. The transaction is expected to close in June 2020, subject to specified closing conditions, including Tetraphase having a minimum amount of net cash as of the closing and approval by Tetraphase stockholders. Upon the closing of the transaction, Tetraphase will become a privately held company and shares of Tetraphase’s common stock will no longer be listed on any public market. Subject to certain limited exceptions, the CVRs will be non-transferable.
