Appendix

Definitions of Non-GAAP Measures (A) Adjusted EBITDA: Adjusted EBITDA, a non-GAAP financial measure, is provided supplementally because it is widely used by investors as a performance and valuation measure in the solid waste industry. Waste Connections’ management uses adjusted EBITDA as one of the principal measures to evaluate and monitor the ongoing financial performance of the Company's operations. Waste Connections defines adjusted EBITDA as net income, plus income tax provision, plus interest expense, plus depreciation and amortization expense, plus closure and post-closure accretion expense, plus or minus any loss or gain on disposal of assets, plus other expense, less other income. The Company further adjusts this calculation to exclude the effects of other items management believes impact the ability to assess the operating performance of our business. This measure is not a substitute for, and should be used in conjunction with, GAAP financial measures. Other companies may calculate adjusted EBITDA differently. (B) Adjusted Free Cash Flow: Adjusted free cash flow, a non-GAAP financial measure, is provided supplementally because it is widely used by investors as a valuation and liquidity measure in the solid waste industry. Waste Connections’ management uses adjusted free cash flow as one of the principal measures to evaluate and monitor the ongoing financial performance of the Company's operations. Waste Connections defines adjusted free cash flow as net cash provided by operating activities, plus proceeds from disposal of assets, plus or minus change in book overdraft, plus excess tax benefit associated with equity-based compensation, less capital expenditures for property and equipment and distributions to non-controlling interests. The Company further adjusts this calculation to exclude the effects of items management believes impact the ability to assess the operating performance of its business. This measure is not a substitute for, and should be used in conjunction with, GAAP liquidity or financial measures. Other companies may calculate adjusted free cash flow differently. 23
