Exhibit 99.1

RENNOVA HEALTH postpones special meeting of stockholders

to may 26, 2017

WEST PALM BEACH, Fla. (May 18, 2017) – Rennova Health, Inc. (NASDAQ: RNVA), (NASDAQ: RNVAZ) (“Rennova” or the “Company”), a vertically integrated provider of industry-leading diagnostics and supportive software solutions to healthcare providers, announces the postponement of its Special Meeting of stockholders that was to have taken place on May 19, 2017. The postponement is necessary to achieve a quorum of shares represented at the meeting. The new date for the Special Meeting is May 26, 2017 at 11:00 a.m. Eastern time and it will take place at the offices of Shutts & Bowen LLP, 525 Okeechobee Boulevard, Suite 1100, West Palm Beach, FL 33401. The record date of April 21, 2017 remains unchanged.

The Special Meeting is for the following purposes:

To approve, for the purpose of Nasdaq Listing Rule 5635(d), the issuance of shares of Common Stock underlying Senior Secured Original Issue Discount Convertible Debentures and three series of Warrants issued by the Company pursuant to the terms of that certain Securities Purchase Agreement, dated as of March 15, 2017, and those certain Exchange Agreements, dated as of March 15, 2017, between the Company and the investors named therein, in an amount in excess of 19.99% of the Company’s Common Stock outstanding before the issuance of such Senior Secured Original Issue Discount Convertible Debentures and Warrants;

To authorize an adjournment of the Special Meeting, if necessary, if a quorum is present, to solicit additional proxies if there are not sufficient votes in favor of Proposal 1; and

To transact such other business as may properly come before the Special Meeting or any adjournment or postponement thereof.

“Although the vast majority of votes cast to date have been in favor of the proposals, the number of shares cast is insufficient for a quorum and our proxy solicitation firm requires more time to solicit votes from our stockholders,” commented Seamus Lagan, chief executive officer of Rennova Health.

Stockholders who have already voted do not need to recast their votes. Stockholders who have not yet voted are encouraged to do so.

Stockholders that own their shares in “street name” through a stock brokerage account or through a bank or nominee should consult the broker, bank or nominee about its procedures to vote the shares.
