Exhibit 99.1

Shareholder Meeting Adjourned to April 26, 2018

Rosetta Genomics Urges Shareholders to Vote FOR the Proposed Merger
with Genoptix

If shareholders do not approve the merger, outstanding ordinary shares likely will cease
to have any value

PHILADELPHIA, PA and REHOVOT, ISRAEL / ACCESSWIRE / April 17, 2018 / Rosetta Genomics Ltd. (the “Company”) (NASDAQ: ROSG) today announced that the extraordinary general meeting of shareholders of that was summoned for April 17, 2018, has been adjourned to Thursday, April 26, 2018 at 10:00 AM (PT) in order to provide additional time for the solicitation of votes in favor of the proposed merger of the Company with a subsidiary of Genoptix, Inc. (“Genoptix”). The adjourned meeting will be held at 25901 Commercentre Dr., Lake Forest, CA 92630. The Company and Genoptix have entered into amendments to the merger agreement and related agreements to permit the necessary extensions of the shareholder meeting date and the outside date for completing the transaction.

The matter to be voted upon at the adjourned meeting, and the record date for the shareholders entitled to vote at the meeting, will remain unchanged. For information regarding the matter to be voted upon at the adjourned meeting, see the Company’s proxy statement filed on Form 6-K with the U.S. Securities and Exchange Commission on March 13, 2018.

The Company urges all its shareholders to vote FOR the proposed merger of Rosetta Genomics with a subsidiary of Genoptix, Inc. If the merger is not adopted by the Company’s shareholders or if the merger is not consummated for any other reason, the Company’s shareholders will not receive any payment for their shares in connection with the merger. In addition, because of the Company’s financial condition and continued operating losses, which, among other things, led the Company’s Board of Directors to recommend the merger, we anticipate that we may be required to seek protection from our creditors, or an involuntary petition for bankruptcy may be filed against us in light of our financial condition. In such a case, it is unlikely that the Company’s ordinary shares would have any value. The Board of Directors has explored many different strategic alternatives and concluded that this proposed merger with Genoptix is the best option for all Rosetta Genomics stakeholders.

If any shareholder has questions on the proposed merger or on voting methods, please call Ron Kalfus, CFO of Rosetta Genomics, at 949-587-7522.
