This document provides an overview of SemGroup's non-GAAP financial measures, forward-looking statements, and strategic growth plan. It discusses SemGroup's Adjusted EBITDA measure and why certain items are excluded. It also notes key limitations of non-GAAP measures and that management compensates for these limitations. An overview is then provided of SemGroup's crude and natural gas assets, operations, and strategic growth areas. Key performance metrics and asset details are highlighted for SemGroup's crude and natural gas businesses.

Non-GAAP Financial Measures
SemGroup’s non-GAAP measure, Adjusted EBITDA, is not a GAAP measure and is not intended to be used in lieu of GAAP presentation of net income (loss),
which is the most closely associated GAAP measure. Adjusted EBITDA represents earnings before interest, taxes, depreciation and amortization, adjusted for
selected items that SemGroup believes impact the comparability of financial results between reporting periods. In addition to non-cash items, we have selected
items for adjustment to EBITDA which management feels decrease the comparability of our results among periods. These items are identified as those which are
generally outside of the results of day to day operations of the business. These items are not considered non-recurring, infrequent or unusual, but do erode
comparability among periods in which they occur with periods in which they do not occur or occur to a greater or lesser degree. Historically, we have selected
items such as gains on the sale of NGL units, costs related to our predecessor’s bankruptcy, significant business development related costs, significant legal
settlements, severance and other similar costs. Management believes these types of items can make comparability of the results of day to day operations among
periods difficult and have chosen to remove these items from our Adjusted EBITDA. We expect to adjust for similar types of items in the future. Although we
present selected items that we consider in evaluating our performance, you should be aware that the items presented do not represent all items that affect
comparability between the periods presented. Variations in our operating results are also caused by changes in volumes, prices, mechanical interruptions and
numerous other factors. We do not adjust for these types of variances.
This measure may be used periodically by management when discussing our financial results with investors and analysts and is presented as management
believes it provides additional information and metrics relative to the performance of our businesses. This non-GAAP financial measure has important limitations
as an analytical tool because it excludes some, but not all, items that affect the most directly comparable GAAP financial measures. You should not consider non-
GAAP measures in isolation or as substitutes for analysis of our results as reported under GAAP. Management compensates for the limitations of our non-GAAP
measures as analytical tools by reviewing the comparable GAAP measures, understanding the differences between the non-GAAP measure and the most
comparable GAAP measure and incorporating this knowledge into its decision-making processes. We believe that investors benefit from having access to the
same financial measures that our management uses in evaluating our operating results. Because all companies do not use identical calculations, our
presentations of non-GAAP measures may be different from similarly titled measures of other companies, thereby diminishing their utility.
