Genoptix Completes Acquisition of PersonalizeDx from Rosetta Genomics

First step in the process of Genoptix acquiring all of Rosetta Genomics 

Next step is the completion of a merger for $8 million in cash pursuant to which value to Rosetta Genomics’ equity holders is preliminarily estimated to be $0.40 – $0.45 per ordinary share, after deductions for debt, warrant termination payments, fees, expenses and other items 

Record date for shareholder meeting to approve the merger is March 9, 2018 and Rosetta Genomics strongly urges shareholders to vote for new transaction as its cash position is insufficient to fund operations beyond a short period of time

CARLSBAD, Calif., PHILADELPHIA and REHOVOT, Israel (March 5, 2018) – Genoptix, Inc., a leading oncology diagnostic laboratory, and Rosetta Genomics Ltd. (NASDAQ: ROSG), a genomic diagnostics company that improves treatment decisions by providing timely and accurate diagnostic information to physicians, jointly announce that they have consummated the first step in their previously announced acquisition by completing the sale of PersonalizeDx to Genoptix for $1 million in cash on March 2, 2018.

The next step in the acquisition is the consummation of the previously announced merger transaction for $8 million in cash.  After deducting expected payments for outstanding debt, convertible debentures, warrant termination payments, professional fees, expenses and other items, this purchase price equates to an amount that is preliminarily estimated to be $0.40 – $0.45, in cash, for each ordinary share of Rosetta Genomics.

The transactions have been unanimously approved by the Board of Directors of both companies, and the closing of the merger is expected to occur during the second quarter of 2018, subject to approval by Rosetta Genomics’ shareholders at an extraordinary meeting of shareholders to be held on April 6, 2018 and to customary closing conditions.   Shareholders of record on March 9, 2018 will be eligible to vote at this meeting.

In connection with the proposed merger, Rosetta Genomics intends to file a proxy statement with the Securities and Exchange Commission (“SEC”).  Shareholders of Rosetta Genomics are urged to carefully review the proxy statement, when available, because it will contain important information about the proposed merger and the estimated closing purchase price for each ordinary share.

Upon closing of the merger, trading in shares of Rosetta Genomics on the Nasdaq Capital Market will cease, and Rosetta Genomics will become a wholly owned subsidiary of Genoptix.
