Exhibit 99.2

Use of Non-GAAP Financial Information—This earnings release supplemental data includes the terms “EBITDA,” “adjusted EBITDA,” “distributable cash flow,” “coverage ratio,” and “adjusted capital spending.” These are non-GAAP financial measures. EBITDA and adjusted EBITDA are included to help facilitate comparisons of operating performance of the Partnership with other companies in our industry. EBITDA and distributable cash flow help facilitate an assessment of our ability to generate sufficient cash flow to make distributions to our partners. We believe that the presentation of EBITDA, adjusted EBITDA and distributable cash flow provides useful information to investors in assessing our financial condition and results of operations. Our coverage ratio is calculated as distributable cash flow divided by total cash distributions and is included to help indicate the Partnership’s ability to pay cash distributions from current earnings. Additionally, adjusted capital spending is a non-GAAP financial measure that demonstrates Phillips 66 Partners' net share of capital spending. The GAAP performance measure most directly comparable to EBITDA and adjusted EBITDA is net income (loss). The GAAP liquidity measure most comparable to EBITDA and distributable cash flow is net cash provided by operating activities. The GAAP financial measure most comparable to our coverage ratio is calculated as net cash provided by operating activities divided by total cash distributions. The GAAP financial measure most comparable to adjusted capital spending is capital expenditures and investments. These non-GAAP financial measures should not be considered as alternatives to their comparable GAAP measures. They have important limitations as analytical tools because they exclude some but not all items that affect their corresponding GAAP measures. They should not be considered in isolation or as substitutes for analysis of our results as reported under GAAP. Additionally, because EBITDA, adjusted EBITDA, distributable cash flow, coverage ratio and adjusted capital spending may be defined differently by other companies in our industry, our definition of those measures may not be comparable to similarly titled measures of other companies, thereby diminishing their utility.

Reconciliations of these non-GAAP measures to their comparable GAAP measures are included in this earnings release supplemental data. Additionally, the disaggregation of adjusted capital spending between expansion and maintenance is not a distinction recognized under GAAP. We provide such disaggregation because our partnership agreement requires that we treat expansion and maintenance capital differently for certain surplus determinations. Further, we generally fund expansion capital spending with both operating and financing cash flows and fund maintenance capital spending with operating cash flows. We believe this is an important distinction in our liquidity profile.
