___________________________________

Newton, MA (September 17, 2014).  Five Star Quality Care, Inc. (NYSE: FVE) today announced its financial results for the quarter and year ended December 31, 2013.

Fourth Quarter 2013 Financial Results:

▪                 Total revenues for the fourth quarter of 2013 increased 0.9% to $325.2 million from $322.5 million for the same period in 2012.  Growth in our revenues was negatively impacted in the fourth quarter of 2013 by the sequestration mandated Medicare payment rate reductions that went into effect on April 1, 2013 and a decrease in occupancy, partially offset by increases in our average monthly rates to residents who pay privately for our services.

▪                 Earnings before interest, taxes, depreciation and amortization, or EBITDA, for the fourth quarter of 2013 were $5.9 million compared to $11.3 million for the same period in 2012.  EBITDA for the fourth quarter of 2013 included $1.0 million of accounting costs incurred in connection with the restatement of certain of our previously issued financial statements.  EBITDA excluding these and certain other items was $7.1 million and $11.4 million in the fourth quarters of 2013 and 2012, respectively. A reconciliation of (loss) income from continuing operations determined in accordance with U.S. generally accepted accounting principles, or GAAP, to EBITDA and EBITDA excluding certain items for the quarters ended December 31, 2013 and 2012 appears later in this press release.

▪                 Loss from continuing operations for the fourth quarter of 2013 was $3.3 million, or $0.07 per basic and diluted share, compared to income from continuing operations of $1.6 million, or $0.04 and $0.03 per share, basic and diluted, respectively, for the same period in 2012.  Loss from continuing operations for the fourth quarter of 2013 included $1.0 million, or $0.02 per basic and diluted share, of general and administrative expenses incurred in connection with the restatement of certain of our previously issued financial statements.  Also, for the fourth quarter of 2013, we incurred increases in our senior living wages and benefits and other senior living operating expenses primarily due to increases in our workers’ compensation and professional and general liability insurance programs, increases in operating expenses as a result of harsh weather conditions experienced during the quarter and increases in general maintenance expenses.

▪                 Net loss for the fourth quarter of 2013 was $5.4 million, or $0.11 per basic and diluted share, compared to net income of $1.6 million, or $0.04 and $0.03 per share, basic and diluted, respectively, for the same period in 2012. Net loss in the fourth quarter of 2013 included a loss from discontinued operations of $2.1 million.  Net income in the fourth quarter of 2012 included a loss from discontinued operations of $47,000.

Fourth Quarter 2013 Operating Results:

▪                 Occupancy at our owned and leased senior living communities for the fourth quarter of 2013 was 85.6% compared to 86.3% for the same period in 2012.

▪                 The average monthly rate at our owned and leased senior living communities for the fourth quarter of 2013 increased by 0.5% to $4,417 from $4,393 for the same period in 2012.

▪                 The percentage of revenues derived from residents’ private resources at our owned and leased senior living communities for the fourth quarter of 2013 increased 70 basis points to 76.8% from 76.1% for the same period in 2012.

Fiscal Year Financial Results:

▪                 Total revenues for the year ended December 31, 2013 increased 7.4% to $1.3 billion from $1.2 billion for the year ended December 31, 2012.  Growth in our revenues was negatively impacted for the year ended December 31, 2013 by the sequestration mandated Medicare payment rate reductions that went into effect on April 1, 2013 and a decrease in occupancy, partially offset by increases in our average monthly rates to residents who pay privately for our services.

▪                 EBITDA for the year ended December 31, 2013 was $36.8 million compared to $47.6 million for the year ended December 31, 2012.  EBITDA for the year ended December 31, 2013 included $1.0 million of accounting costs incurred in connection with the restatement of certain of our previously issued financial statements.  EBITDA for the year ended December 31, 2012 included a gain on settlement of our litigation with Sunrise Senior Living, Inc., or Sunrise, which increased EBITDA by $3.4 million.  EBITDA excluding the restatement costs, the litigation settlement and certain other items was $38.8 million and $44.3 million for the year ended December 31, 2013 and 2012, respectively.  A reconciliation of income from continuing operations determined in accordance with GAAP to EBITDA and EBITDA excluding certain items for the years ended December 31, 2013 and 2012 appears later in this press release.

▪                 Income from continuing operations for the year ended December 31, 2013 was $3.4 million, or $0.07 per basic and diluted share, compared to $10.6 million, or $0.23 per basic and diluted share, for the year ended December 31, 2012.  Income from continuing operations for the year ended December 31, 2013 included $1.0 million, or $0.02 per basic and diluted share, of general and administrative expenses incurred in connection with the restatement of certain of our previously issued financial statements, a loss on early extinguishment of debt of $599,000, or $0.01 per basic and diluted share, and an income tax benefit of $1.5 million, or $0.03 per basic and diluted share, relating to a work opportunity tax credit program that expired in 2012 and then was retroactively reinstated in January 2013.  Also, for the year ended December 31, 2013, we incurred increases in our senior living wages and benefits and other senior living operating expenses primarily due to increases in employee health insurance, increases in our workers’ compensation and professional and general liability insurance programs, increases in operating expenses as a result of harsh weather conditions experienced during the fourth quarter of 2013 and increases in general maintenance expenses.  Income from continuing operations for the year ended December 31, 2012 included a gain on settlement of our litigation with Sunrise of $2.0 million (net of taxes), or $0.04 per basic and diluted share.

▪                 Net loss for the year ended December 31, 2013 was $2.3 million, or $0.05 per basic and diluted share, compared to net income of $22.3 million, or $0.47 and $0.46 per share, basic and diluted, respectively, for the year ended December 31, 2012.  Net loss for the 2013 period included a loss from discontinued operations of $5.8 million.  Net income for the 2012 period included income from discontinued operations of $11.7 million and was primarily impacted by a $23.3 million gain on sale that we recorded related to the sale of our pharmacy business, partially offset by income tax expense of $5.4 million and other losses incurred at our discontinued senior living communities and rehabilitation hospitals.

Expansion and Disposition Activities:

Since October 1, 2013, we have begun managing four communities with a combined 281 living units and we have acquired one assisted living community with 116 living units:

▪                 In October 2013, we began managing two senior living communities in Georgia with a combined total of 153 living units and a senior living community in Tennessee with 60 living units.  In November 2013, we began managing a senior living community in Wisconsin with 68 living units.  These four communities are owned by Senior Housing Properties Trust, or SNH, and leased to one of its taxable REIT subsidiaries.

▪                 In May 2014, we acquired an assisted living community with 116 living units located in Dothan, Alabama for approximately $19.9 million, including the assumption of approximately $13.9 million of mortgage debt and excluding

closing costs.  We funded this acquisition with cash on hand and borrowings under our $150.0 million revolving credit facility.

Since October 1, 2013, we and SNH have disposed of two rehabilitation hospitals, including 13 affiliated out-patient clinics, with a combined 321 beds, and three senior living communities with a combined 203 living units:

▪                 As of December 31, 2013, we and SNH completed the transfer of operations and sale of the real estate at two rehabilitation hospitals and 13 out-patient clinics affiliated with those rehabilitation hospitals, which were previously disclosed as held for sale and discontinued operations.  We previously leased the rehabilitation hospitals from SNH and the out-patient clinics from others.  As a result of this transaction, SNH received proceeds of approximately $90.0 million for the sale of the real estate associated with the rehabilitation hospitals, we retained certain net assets of approximately $9.6 million and our annual rent payable to SNH and others decreased by approximately $11.5 million.  In 2013, we recorded losses of approximately $2.2 million relating to closing costs and legal fees associated with this transaction and we incurred $2.6 million of non-cash asset impairment charges to reduce the fixed assets we owned which are related to the rehabilitation hospitals to their estimated fair market values.

▪                 In January 2014, SNH sold an assisted living community with 48 living units that we leased from SNH that was previously disclosed as held for sale for a sales price of $2.4 million.  As a result of this sale, our annual minimum rent payable to SNH decreased by $210,000 in accordance with the terms of the applicable lease.

▪                 In June 2014, SNH sold two skilled nursing facilities, or SNFs, with a combined total of 155 living units that we leased from SNH that were previously disclosed as held for sale for a sales price of $4.5 million.  As a result of this sale, our annual minimum rent payable to SNH decreased by $450,000 in accordance with the terms of the applicable lease.

As of the date of this press release, we and SNH continue to market for sale seven senior living communities with a combined total of 509 living units that were previously disclosed as held for sale and discontinued operations.

RECONCILIATION OF NON-GAAP FINANCIAL MEASURES

(in thousands)

Earnings before interest, taxes, depreciation and amortization, or EBITDA, and EBITDA excluding certain items, and EBITDA excluding certain items plus rent expense (EBITDAR excluding certain items), or collectively, Non-GAAP financial measures, are not financial measures determined according to U.S. generally accepted accounting principles, or GAAP.  We consider these Non-GAAP financial measures to be meaningful disclosures because we believe that the presentation of these Non-GAAP financial measures may help investors to gain a better understanding of changes in our operating results, and may also help investors who wish to make comparisons between us and other companies on both a GAAP and a non-GAAP basis. These Non-GAAP financial measures are used by management to evaluate our financial performance and for comparing our performance over time and to the performance of our competitors. These Non-GAAP financial measures as presented may not, however, be comparable to amounts calculated by other companies.  This information should not be considered as an alternative to income from continuing operations, net income, cash flows from operating activities or any other financial operating or performance or liquidity measure established by GAAP.  The following table includes the reconciliation of these Non-GAAP financial measures to income from continuing operations, the most directly comparable financial measure under GAAP reported in our consolidated financial statements, for the three and twelve months ended December 31, 2013 and 2012.
