Exhibit 99.1

AdCare Health Systems Announces Notice of Noncompliance with NYSE MKT Listing Standards

ATLANTA, GA—(May 23, 2013) - AdCare Health Systems, Inc. (NYSE MKT: ADK) (NYSE MKT: ADK.PRA) (the “Company”), a leading long-term care provider, today announced that, on May 17, 2013, the Company received a deficiency letter from the NYSE MKT LLC (the “Exchange”) indicating that the Exchange has determined that the Company is not in compliance with Sections 134 and 1101 of the Exchange’s Company Guide (the “Company Guide”) due to the Company’s indication in its Form 12b-25, filed with the Securities and Exchange Commission (“SEC”) on April 16, 2013, that the Company is not able to file its Quarterly Report on Form 10-Q for the quarter ended March 31, 2013 (the “Form 10-Q”) with the SEC by the requisite deadline.  As previously disclosed, the Company received a deficiency letter from the Exchange on April 17, 2013 that it is not in compliance with Sections 134 and 1101 of the Company Guide due to its failure to file its Annual Report on Form 10-K for the year ended December 31, 2012 with the SEC by the requisite deadline.

In the deficiency letter issued to the Company in April, the Exchange advised the Company that, in order to maintain its listing of securities on the Exchange, the Company must submit a plan to the Exchange by May 1, 2013, detailing the action it had taken, or would take, that would bring it into compliance with the continued listing standards of the Company Guide by July 16, 2013.  The Company provided to the Exchange the Company’s plan and supporting documentation on May 1, 2013.

In the deficiency letter issued to the Company in May, the Exchange indicated that, due to the similar nature of the deficiencies identified in the April and May deficiency letters, the Company is not required to submit an additional plan of compliance in connection with its failure to timely file the Form 10-Q.  If the Company chooses, it may supplement its plan, no later than May 31, 2013, to address how it intends to regain compliance with Sections 134 and 1101 of the Company Guide, with respect to filing of the Form 10-Q, by August 15, 2013.  The Company intends on providing supplemental materials to the Exchange in support of its plan by May 31, 2013.

The Company remains subject to the conditions set forth in the deficiency letter issued to the Company in April.  Accordingly, if its plan is not accepted by the Exchange, or if the Company is not in compliance with the Exchange’s continued listing standards within the timeframe provided or does not make progress consistent with its plan by July 16, 2013, then the Exchange will initiate delisting proceedings as it deems appropriate.
