Appendix Brean Capital Conference—May 2013 36

Adjusted EBITDA represents earnings before interest, taxes, depreciation, depletion and amortization (“EBITDA”) adjusted for sales discounts and the interest, taxes, depreciation, depletion and amortization attributable to equity earnings in our unconsolidated affiliates. EBITDA reflects sales discounts included as a reduction in sales and other operating revenue. The sales discounts represent the sharing with customers of a portion of nonconventional fuel tax credits, which reduce our income tax expense. However, we believe our Adjusted EBITDA would be inappropriately penalized if these discounts were treated as a reduction of EBITDA since they represent sharing of a tax benefit that is not included in EBITDA. Accordingly, in computing Adjusted EBITDA, we have added back these sales discounts. Our Adjusted EBITDA also includes EBITDA attributable to our unconsolidated affiliates. EBITDA and Adjusted EBITDA do not represent and should not be considered alternatives to net income or operating income under GAAP and may not be comparable to other similarly titled measures in other businesses. Adjusted EBITDA does not represent and should not be considered as an alternative to net income as determined by GAAP, and calculations thereof may not be comparable to those reported by other companies. We believe Adjusted EBITDA is an important measure of operating performance and provides useful information to investors because it highlights trends in our business that may not otherwise be apparent when relying solely on GAAP measures and because it eliminates items that have less bearing on our operating performance. Adjusted EBITDA is a measure of operating performance that is not defined by GAAP and should not be considered a substitute for net (loss) income as determined in accordance with GAAP. Adjusted EBITDA attributable to SXC/SXCP equals Adjusted EBITDA less Adjusted EBITDA attributable to noncontrolling interests. • Adjusted EBITDA/Ton represents Adjusted EBITDA divided by tons sold. When applicable to Adjusted EBITDA attributable to SXC or SXCP, tons sold are prorated according to the respective ownership interest of SXC or SXCP as applicable. Definitions 37 Brean Capital Conference—May 2013

Distributable Cash Flow equals Adjusted EBITDA less net cash paid for interest expense, on-going capital expenditures, accruals for replacement capital expenditures, and cash distributions to noncontrolling interests. Distributable Cash Flow is a non-GAAP supplemental financial measure that management and external users of the Partnership’s financial statements, such as industry analysts, investors, lenders, and rating agencies, use to assess: the Partnership’s operating performance as compared to other publicly traded partnerships, without regard to historical cost basis; the ability of the Partnership’s assets to generate sufficient cash flow to make distributions to the Partnership’s unitholders; the Partnership’s ability to incur and service debt and fund capital expenditures; and the viability of acquisitions and other capital expenditure projects and the returns on investment of various investment opportunities. The Partnership believes that Distributable Cash Flow provides useful information to investors in assessing the Partnership’s financial condition and results of operations. Distributable Cash Flow should not be considered an alternative to net income, operating income, cash flows from operating activities, or any other measure of financial performance or liquidity presented in accordance with generally accepted accounting principles (GAAP). Distributable Cash Flow has important limitations as an analytical tool because it excludes some, but not all, items that affect net income and net cash provided by operating activities and used in investing activities. Additionally, because Distributable Cash Flow may be defined differently by other companies in the industry, the Partnership’s definition of Distributable Cash Flow may not be comparable to similarly titled measures of other companies, thereby diminishing their utility.
