AdCare Health Systems Provides Update on the Status of its First Quarter 2013 Quarterly Report and Releases Preliminary Unaudited Financial Data for First Quarter 2013

ATLANTA, GA--(May 17, 2013) - AdCare Health Systems, Inc. (NYSE MKT: ADK) (NYSE MKT: ADK.PRA), a leading long-term care provider, announced that, as expected, it did not file its Quarterly Report on Form 10-Q for the quarter ended March 31, 2013 (the “2013 First Quarter Report”) by the filing deadline of May 15, 2013 and would not be in a position to file such report by the extended filing deadline of May 20, 2013 afforded by Rule 12b-25 under the Securities Exchange Act of 1934, as amended. The Company is also furnishing in this release certain preliminary unaudited financial data for the quarter ended March 31, 2013. This data has not been reviewed by the Company’s independent registered public accounting firm.

As previously disclosed, the Audit Committee of the Company’s Board of Directors, in consultation with management, concluded that: (i) the Company’s previously issued financial statements for the quarters ended March 31, 2012, June 30, 2012 and September 30, 2012 (the “Relevant Financial Statements”) should no longer be relied upon due to errors in the Relevant Financial Statements identified in connection with the audit of the Company’s financial statements for the year ended December 31, 2012; and (ii) the Company would restate the Relevant Financial Statements by amending its Quarterly Reports on Form 10-Q for the quarters ended March 31, 2012, June 30, 2012 and September 30, 2012 (the “2012 Quarterly Reports”). The Audit Committee initiated a further review of, and inquiry with respect to, the accounting and financial issues related to these and other potential errors and engaged counsel to assist the Audit Committee with such matters. The Audit Committee has completed its inquiry and, in connection therewith, assisted in the correction of certain errors relating to accounting and financial matters and identified certain material weaknesses in the Company’s internal control over financial reporting. These material weaknesses include, among other things, weakness in the Company’s ability to appropriately account for complex or non-routine transactions and in the quality and sufficiency of the Company’s finance and accounting resources.

In addition, Martin D. Brew resigned as the Company’s Chief Financial Officer on April 15, 2013, and Ronald W. Fleming commenced serving as the Company’s Chief Financial Officer on May 15, 2013.

The restatement process for the 2012 Quarterly Reports and the audit of the Company’s financial statements for the year ended December 31, 2012 is ongoing. In addition, Mr. Fleming, the Company’s new Chief Financial Officer, is in the process of becoming knowledgeable with respect to the Company’s business, operations, accounting and finances so that he may be in a position to provide the required certifications under the Sarbanes-Oxley Act of 2002 for the 2012 Quarterly Reports, the Company’s Annual Report on Form 10-K for the year ended December 31, 2012 (the “Annual Report”), and the 2013 First Quarter Report, among other things. As a result of the foregoing, the Company is unable to file its 2013 First Quarter Report within the prescribed period. The Company anticipates filing: (i) the 2012 Quarterly Reports and the Annual Report by June 30, 2013; and (ii) the 2013 First Quarter Report by July 15, 2013.

The Company anticipates the following with respect to the unaudited financial data for the quarter ended March 31, 2013 specified below:

·                  Total revenues for the quarter ended March 31, 2013 ranging from $56.0 million to $59.0 million;

·                  Net loss for the quarter ended March 31, 2013 ranging from $1.1 million to $2.2 million (excluding the special charge discussed below);

·                  Total assets at March 31, 2013 ranging from $225.0 million to $231.0 million;

·                  Total liabilities at March 31, 2013 ranging from $203.0 million to $209.0 million; and

·                  Total stockholders’ equity at March 31, 2013 ranging from $20.7 million to $22.2 million.

In connection with the restatement process and the Audit Committee’s review and inquiry, the Company has incurred, and will continue to incur, significant professional services costs and other expenses which will be recognized as a special charge in the first and second quarters of 2013. The Company anticipates that this special charge will be material and, for the quarter ended March 31, 2013, will be in the range of $1.2 million to $1.5 million.

The foregoing unaudited financial data does not consolidate the results of the five entities which own the five skilled nursing facilities located in Oklahoma which are managed by the Company (known as the “Oklahoma Entities”). During the first three quarters of 2012, the Company recognized the Oklahoma Entities as “variable interest entities” and, accordingly, consolidated their results with the results of the Company. During the course of the restatement process and the audit, the Company has determined that the Oklahoma Entities should not be recognized as variable interest entities and their results should not be consolidated with the results of the Company.
