Appendix

Appendix We use the following Non-GAAP Financial Measures that we believe are useful to investors as key valuation and operating performance measures: EBITDA We believe EBITDA is useful to an investor in evaluating our operating performance because it helps investors evaluate and compare the results of our operations from period to period by removing the impact of our capital structure (interest and lease expense) and our asset base (depreciation and amortization expense) from our operating results. In addition, covenants in our debt agreements use EBITDA as a measure of financial compliance. Adjustments to EBITDA We adjust EBITDA when evaluating our performance because we believe that the exclusion of certain additional items described below provides useful supplemental information to investors regarding, in the case of EBITDAR, the value of our business, and, in the case of EBITDA, our ongoing operating performance. We believe that the presentation of Adjusted EBITDA, when combined with GAAP net income (loss) attributable to Genesis Healthcare, Inc., and EBITDA, is beneficial to an investor’s complete understanding of our operating performance. In addition, such adjustments are substantially similar to the adjustments EBITDA provided for in the financial covenant calculations contained in our lease and debt agreements. We adjust EBITDA for the following items:  Loss on extinguishment of debt. We recognize losses on the extinguishment of debt when we refinance our debt prior to its original term, requiring us to write-off any unamortized deferred financing fees. We exclude the effect of losses or gains recorded on the early extinguishment of debt because we believe these gains and losses do not accurately reflect the underlying performance of our operating businesses.  Other loss (income). We primarily use this income statement caption to capture gains and losses on the sale or disposition of assets. We exclude the effect of such gains and losses because we believe they do not accurately reflect the underlying performance of our operating businesses.  Transaction costs. In connection with our acquisition and disposition transactions, we incur costs consisting of investment banking, legal, transaction-based compensation and other professional service costs. We exclude acquisition and disposition related transaction costs expensed during the period because we believe these costs do not reflect the underlying performance of our operating businesses.  Customer receivership. We exclude the non-cash costs related to a customer receivership and the related write-down of unpaid accounts receivable. We believe these costs do not accurately reflect the underlying performance of our operating businesses.  Long-lived asset impairments. We exclude non-cash long-lived asset impairment charges because we believe including them does not reflect the ongoing operating performance of our operating businesses. Additionally, such impairment charges represent accelerated depreciation expense, and depreciation expense is excluded from EBITDA.  Goodwill and identifiable intangible asset impairments. We exclude non-cash goodwill and identifiable intangible asset impairment charges because we believe including them does not reflect the ongoing operating performance of our operating businesses.  Severance and restructuring. We exclude severance costs from planned reduction in force initiatives associated with restructuring activities intended to adjust our cost structure in response to changes in the business environment. We believe these costs do not reflect the underlying performance of our operating businesses. We do not exclude severance costs that are not associated with such restructuring activities. 18

Appendix Losses of newly acquired, constructed or divested businesses. The acquisition and construction of new businesses is an element of our growth strategy. Many of the businesses we acquire have a history of operating losses and continue to generate operating losses in the months that follow our acquisition. Newly constructed or developed businesses also generate losses while in their start-up phase. We view these losses as both temporary and an expected component of our long-term investment in the new venture. We adjust these losses when computing Adjusted EBITDA in order to better analyze the performance of our mature ongoing business. The activities of such businesses are adjusted when computing Adjusted EBITDA until such time as a new business generates positive Adjusted EBITDA. The operating performance of new businesses is no longer adjusted when computing Adjusted EBITDA beginning in the period in which a new business generates positive Adjusted EBITDA and all periods thereafter. The divestiture of underperforming or non-strategic facilities is also an element of our business strategy. We eliminate the results of divested facilities beginning in the quarter in which they become divested. We view the losses associated with the wind-down of such divested facilities as not indicative of the performance of our ongoing operating business.    Stock-based compensation. We exclude stock-based compensation expense because it does not result in an outlay of cash and such non-cash expenses do not reflect the underlying operating performance of our operating businesses.  Other Items. From time to time we incur costs or realize gains that we do not believe reflect the underlying performance of our operating businesses. In the current reporting period, we incurred the following expenses that we believe are non-recurring in nature and do not reflect ongoing operating performance of the Company or our operating businesses. (1) Skilled Healthcare and other loss contingency expense – We exclude the estimated settlement cost and any adjustments thereto regarding the four legal matters inherited by Genesis in the Skilled and Sun Transactions and disclosed in the commitments and contingencies footnote to our consolidated financial statements describing our material legal proceedings. In the nine months ended September 30, 2016, we increased our estimated loss contingency expense by $15.2 million, respectively, related to these matters. We believe these costs are non-recurring in nature as they will no longer be recognized following the final settlement of these matters. We do not exclude the estimated settlement costs associated with all other legal and regulatory matters arising in the normal course of business. Also, we do not believe the excluded costs reflect the underlying performance of our operating businesses. (1) Regulatory defense and related costs – We exclude the costs of investigating and defending the matters associated with the Skilled Healthcare and other loss contingency expense as noted in footnote (1). We believe these costs are non-recurring in nature as they will no longer be recognized following the final settlement of these matters. Also, we do not believe the excluded costs reflect underlying performance of our operating businesses. (1) Other non-recurring costs – In the three and nine months ended September 30, 2017, we excluded $3.5 million of costs, primarily incurred in connection with the removal of a non cash actuarially developed discount related to the settlement of workers’ compensation claims for policy years 2012 and prior. In the three and nine months ended September 30, 2016, we excluded ($0.1) million and $0.8 million, respectively, of costs related to previously reported periods and a regulatory audit associated with acquired businesses and related to pre-acquisition periods. We do not believe the excluded costs are recurring or reflect the underlying performance of our operating businesses. See the reconciliation of net loss attributable to Genesis Healthcare, Inc. to EBITDA and Adjusted EBITDA included herein. Adjusted EBITDAR We use Adjusted EBITDAR as one measure in determining the value of prospective acquisitions or divestitures. Adjusted EBITDAR is also a commonly used measure to estimate the enterprise value of businesses in the healthcare industry. In addition, covenants in our lease agreements use Adjusted EBITDAR as a measure of financial compliance. The adjustments made and previously described in the computation of Adjusted EBITDA are also made when computing Adjusted EBITDAR. See the reconciliation of net loss attributable to Genesis Healthcare, I1n9c. to Adjusted EBITDAR included herein.
