Appendix Second Quarter 2017 Earnings Call

Non-GAAP Financial Measures Non-GAAP Financial Measures We use non-GAAP financial measures EBITDA, Adjusted EBITDA, Distributable Cash Flow and Distribution Coverage Ratio. EBITDA represents net income available to us before deducting interest expense, income taxes and depreciation, amortization and accretion. Adjusted EBITDA represents EBITDA as further adjusted to exclude equity funded expenses related to incentive compensation and the Amended Omnibus Agreement, gains or losses on sales of assets, certain discrete acquisition related costs, such as legal and other professional fees and severance expenses associated with recently acquired companies, and certain other discrete non-cash items arising from purchase accounting. Distributable Cash Flow represents Adjusted EBITDA less cash interest expense, sustaining capital expenditures and current income tax expense. Distribution Coverage Ratio is computed by dividing Distributable Cash Flow by the weighted average diluted common and subordinated units and then dividing that result by the distributions paid per limited partner unit. EBITDA, Adjusted EBITDA, Distributable Cash Flow and Distribution Coverage Ratio are used as supplemental financial measures by management and by external users of our financial statements, such as investors and lenders. EBITDA and Adjusted EBITDA are used to assess our financial performance without regard to financing methods, capital structure or income taxes and the ability to incur and service debt and to fund capital expenditures. In addition, Adjusted EBITDA is used to assess the operating performance of our business on a consistent basis by excluding the impact of items which do not result directly from the wholesale distribution of motor fuel, the leasing of real property, or the day to day operations of our retail site activities. EBITDA, Adjusted EBITDA, Distributable Cash Flow and Distribution Coverage Ratio are also used to assess the ability to generate cash sufficient to make distributions to our unit-holders. We believe the presentation of EBITDA, Adjusted EBITDA, Distributable Cash Flow and Distribution Coverage Ratio provides useful information to investors in assessing the financial condition and results of operations. EBITDA, Adjusted EBITDA, Distributable Cash Flow and Distribution Coverage Ratio should not be considered alternatives to net income or any other measure of financial performance or liquidity presented in accordance with U.S. GAAP. EBITDA, Adjusted EBITDA, Distributable Cash Flow and Distribution Coverage Ratio have important limitations as analytical tools because they exclude some but not all items that affect net income. Additionally, because EBITDA, Adjusted EBITDA, Distributable Cash Flow and Distribution Coverage Ratio may be defined differently by other companies in our industry, our definitions may not be comparable to similarly titled measures of other companies, thereby diminishing their utility.

(b)Relates to certain discrete acquisition related costs, such as legal and other professional fees, severance expenses and purchase accounting adjustments associated with recently acquired businesses. Acquisition-related costs for the three and six months ended June 30, 2017 include severance and benefit expense and retention bonuses paid to certain EICP participants associated with CST’s merger with Couche-Tard. (c)Under the Partnership Agreement, sustaining capital expenditures are capital expenditures made to maintain our long-term operating income or operating capacity. Examples of sustaining capital expenditures are those made to maintain existing contract volumes, including payments to renew existing distribution contracts, or to maintain our sites in conditions suitable to lease, such as parking lot or roof replacement/renovation, or to replace equipment required to operate the existing business. (d)On July 26, 2017, the Board approved a quarterly distribution of $0.6225 per unit attributable to the second quarter of 2017. The distribution is payable on August 14, 2017 to all unitholders of record on August 7, 2017. (e)The distribution coverage ratio is computed by dividing Distributable Cash Flow by the weighted average diluted common and subordinated units and then dividing that result by the distributions paid per limited partner unit.
