ProPhase Labs Rejects Matrixx 1.60/Share Bid The Rejection:
ProPhase Labs PRPH announced Monday that it has rejected the revised and unsolicited, non-binding proposal from Matrixx Initiatives to acquire the Company for $1.60 per share in cash. This most recent proposal, like their prior $1.40 per share proposal, is conditioned on further due diligence by Matrixx. On October 9, 2012, ProPhase received a revised non-binding proposal, on essentially the same terms as Matrixx's earlier offer, except that in the recent proposal Matrixx raised the proposed price by 20 cents per share. In response to this latest proposal from Matrixx, the Company again sought advice from its independent financial advisors. At a meeting held on October 24, 2012, the Company's Board of Directors unanimously voted to reject this latest Matrixx proposal after careful consideration and consultation with its advisors.
