CAMBRIDGE, Mass., Sept. 19, 2017 (GLOBE NEWSWIRE) -- Dimension Therapeutics, Inc. (Nasdaq:DMTX), a leader in discovering and developing new therapeutic products for people living with devastating rare and metabolic diseases associated with the liver, announced today that its Board of Directors has determined in good faith, after consultation with its financial advisor and outside legal counsel, that the non-binding, unsolicited proposal from Ultragenyx Pharmaceutical Inc. (Nasdaq:RARE) to acquire Dimension for $5.50 per share in cash could reasonably be expected to lead to a “Superior Proposal” as defined in Dimension’s merger agreement with REGENXBIO Inc. (Nasdaq:RGNX) (“REGENXBIO”). As previously announced, the Ultragenyx proposal is subject to, among other things, diligence to be conducted, various closing conditions and regulatory approvals.
Under the REGENXBIO agreement, the Dimension Board’s determination allows Dimension, subject to Ultragenyx’s entry into a customary confidentiality agreement with Dimension, to provide information to and conduct discussions and negotiations with Ultragenyx. Dimension’s Board has not determined that Ultragenyx’s proposal in fact constitutes a Superior Proposal under the existing merger agreement with REGENXBIO and has not changed its recommendation in support of the merger with REGENXBIO.
There can be no assurance that the discussions with Ultragenyx will result in the Dimension Board’s determination that the Ultragenyx proposal is a Superior Proposal or the consummation of a transaction that is superior to the pending transaction with REGENXBIO or that the terms of any new transaction will be the same as those reflected in Ultragenyx’s proposal.
As announced on August 25, 2017, Dimension entered into a definitive merger agreement with REGENXBIO, a leading clinical-stage biotechnology company, under which REGENXBIO will acquire Dimension in an all-stock transaction. Under the terms of the merger agreement, each Dimension stockholder will receive 0.1573 shares of REGENXBIO Common Stock in exchange for each of their shares in Dimension.
Dimension will have no further comment on Ultragenyx’s proposal until the Board has completed discussions and/or negotiations with Ultragenyx.
MTS Health Partners, L.P. is serving as financial advisor to Dimension, and Goodwin Procter LLP is serving as legal counsel.
