Reconciliation of Non-GAAP Financial Measures

Adjusted Operating Income Reconciliation

Adjusted operating income is not a measure of financial performance under generally accepted accounting principles (“GAAP”). The Company believes adjusted operating income provides a relevant measure of operating profitability and a useful basis for evaluating the ongoing operations of the Company. Adjusted operating income is used by the Company to assess operating income before the impact of IPO-related expenses, expenses terminated in connection with the IPO, M&A and acquisition-related costs and certain non-cash items. Adjusted operating income should not be considered in isolation or as a substitute for operating income or other profitability data prepared in accordance with GAAP. Adjusted operating income, as presented, may not be comparable to similarly titled measures of other companies. Set forth below is a reconciliation of adjusted operating income to operating income.

Adjusted Net Income and Adjusted Earnings per Share Reconciliation

Adjusted net income and adjusted earnings per share (EPS) are non-GAAP measures. The Company believes these measures provide a useful indication of profitability and basis for assessing the operations of the Company without the impact of IPO-related expenses, expenses terminated in connection with the IPO, bond redemption premiums, M&A and acquisition related costs and certain non-cash items.

Adjusted net income should not be considered in isolation or as a substitute for net income or other profitability metrics prepared in accordance with GAAP. Adjusted net income, as presented, may not be comparable to similarly titled measures of other companies.

Set forth below is a reconciliation of adjusted net income to net income.

Free Cash Flow Reconciliation

The Company believes free cash flow provides a relevant measure of liquidity and a useful basis for assessing the Company’s ability to fund its activities, including the financing of acquisitions, debt service, stock repurchases and distribution of earnings to shareholders. Free cash flow is calculated as cash flows from operations less cash capital expenditures. Free cash flow is not a measure of financial performance under GAAP. Free cash flow should not be considered in isolation or as a substitute for cash flows from operations or other liquidity measures prepared in accordance with GAAP. Free cash flow, as presented, may not be comparable to similarly titled measures of other companies. Set forth below is a reconciliation of free cash flow to cash flows from operations.

Reconciliation of Free Cash Flow from Operating Cash Flow

EBITDA and Adjusted EBITDA Reconciliation

The common definition of EBITDA is “earnings before interest expense, taxes, depreciation and amortization.” In evaluating liquidity and performance, the Company uses earnings before interest expense, share based compensation, taxes, depreciation and amortization, M&A and acquisition-related costs and one-time IPO-related expenses, or “adjusted EBITDA.” EBITDA and adjusted EBITDA are not measures of financial performance or liquidity under GAAP. EBITDA and adjusted EBITDA should not be considered in isolation or as a substitute for net income, cash flows from operations or other income or cash flows data prepared in accordance with GAAP. EBITDA and adjusted EBITDA, as presented, may not be comparable to similarly titled measures of other companies. EBITDA and adjusted EBITDA are used by certain investors as measures to assess the Company’s ability to service debt. Adjusted EBITDA is also used in the Company’s debt covenants, although the precise adjustments used to calculate adjusted EBITDA included in the Company’s credit facility and indentures vary in certain respects among such agreements and from those presented below. Certain adjustments to adjusted EBITDA were excluded from the calculations below consistent with the adjustments made for adjusted operating income and adjusted net income. Set forth below is a reconciliation of EBITDA and adjusted EBITDA to cash flows from operations and net income.
