TR TARGA INVESTOR PRESENTATION 25#26Non-GAAP Financial Measures This presentation includes the Company's non-GAAP financial measures: adjusted EBITDA, distributable cash flow, and adjusted free cash flow. The following tables provide reconciliations of these non- GAAP financial measures to their most directly comparable GAAP measures. The Company utilizes non-GAAP measures to analyze the Company's performance. Adjusted EBITDA, distributable cash flow, adjusted free cash flow and adjusted operating margin (segment) are non- GAAP measures. The GAAP measures most directly comparable to these non-GAAP measures are income (loss) from operations, Net income (loss) attributable to Targa Resources Corp. and segment operating margin. These non-GAAP measures should not be considered as an alternative to GAAP measures and have important limitations as analytical tools. Investors should not consider these measures in isolation or as a substitute for analysis of the Company's results as reported under GAAP. Additionally, because the Company's non-GAAP measures exclude some, but not all, items that affect income and segment operating margin, and are defined differently by different companies within the Company's industry, the Company's definitions may not be comparable with similarly titled measures of other companies, thereby diminishing their utility. Management compensates for the limitations of the Company's non-GAAP measures as analytical tools by reviewing the comparable GAAP measures, understanding the differences between the measures and incorporating these insights into the Company's decision-making processes. Adjusted EBITDA The Company defines adjusted EBITDA as Net income (loss) attributable to Targa Resources Corp. before interest, income taxes, depreciation and amortization, and other items that the Company believes should be adjusted consistent with the Company's core operating performance. The adjusting items are detailed in the adjusted EBITDA reconciliation table and its footnotes. Adjusted EBITDA is used as a supplemental financial measure by the Company and by external users of the Company's financial statements such as investors, commercial banks and others to measure the ability of the Company's assets to generate cash sufficient to pay interest costs, support the Company's indebtedness and pay dividends to the Company's investors. Distributable Cash Flow and Adjusted Free Cash Flow The Company defines distributable cash flow as adjusted EBITDA less cash interest expense on debt obligations, cash tax (expense) benefit and maintenance capital expenditures (net of any reimbursements of project costs). The Company defines adjusted free cash flow as distributable cash flow less growth capital expenditures, net of contributions from noncontrolling interest and net contributions to investments in unconsolidated affiliates. Distributable cash flow and adjusted free cash flow are performance measures used by the Company and by external users of the Company's financial statements, such as investors, commercial banks and research analysts, to assess the Company's ability to generate cash earnings (after servicing the Company's debt and funding capital expenditures) to be used for corporate purposes, such as payment of dividends, retirement of debt or redemption of other financing arrangements.

Gains or losses on debt repurchases or early debt extinguishments. (In millions) (3) Non-GAAP Measures Reconciliation (11) CHP Includes financial advisory, legal and other professional fees, and other one-time transaction costs. Risk management activities related to derivative instruments including the cash impact of hedges acquired in the 2015 mergers with Atlas Energy L.P. and Atlas Pipeline Partners L.P. The cash impact of the acquired hedges ended in December 2017. Represents one-time severance and related benefit expense related to the Company's cost reduction measures. Noncontrolling interest portion of depreciation and amortization expense (including the effects of the impairment of long-lived assets on non-controlling interests). Beginning in the second quarter of 2019, we revised our reconciliation of Net Income (Loss) attributable to TRC to Adjusted EBITDA to exclude the Splitter Agreement adjustment previously included in the comparative periods presented herein. For all comparative periods presented, our Adjusted EBITDA measure previously included the Splitter Agreement adjustment, which represented the recognition of the annual cash payment received under the condensate splitter agreement ratably over four quarters. The effect of these revisions reduced TRC's Adjusted EBITDA by $75.2 million and $43.0 million for 2018 and 2017. There was no impact to Distributable Cash Flow. In Distributable Cash Flow, Splitter Agreement represents the annual cash payment in the period received. Excludes amortization of interest expense. Represents capital expenditures, net of contributions from noncontrolling interests and includes net contributions to investments in unconsolidated affiliates. Includes an adjustment, reflecting the benefit from net operating loss carryback to 2015 and 2014, which was recognized over the periods between the third quarter 2016 recognition of the receivable and the anticipated receipt date of the refund. The refund, previously expected to be received on or before the fourth quarter of 2017, was received in the second quarter of 2017. The remaining $20.9 million unamortized balance of the tax refund was therefore included in Distributable Cash Flow in the second quarter of 2017. Also includes a refund of Texas margin tax paid in previous periods and received in 2017.
