LINK TO EARNINGS TABLES AND PRESENTATION: https://ir.oneok.com/financial-information/financial-reports NON-GAAP (GENERALLY ACCEPTED ACCOUNTING PRINCIPLES) FINANCIAL MEASURES: ONEOK has disclosed in this news release adjusted earnings before interest, taxes, depreciation and amortization (adjusted EBITDA), a non-GAAP financial metric used to measure the company’s financial performance. Adjusted EBITDA is defined as net income adjusted for interest expense, depreciation and amortization, noncash impairment charges, income taxes, noncash compensation expense, and other noncash items; and includes adjusted EBITDA from the company’s unconsolidated affiliates using the same recognition and measurement methods used to record equity in net earnings from investments. Adjusted EBITDA from unconsolidated affiliates is calculated consistently with the definition above and excludes items such as interest expense, depreciation and amortization, income taxes and other noncash items. Adjusted EBITDA is useful to investors because it and similar measures are used by many companies in the industry as a measure of financial performance and is commonly employed by financial analysts and others to evaluate ONEOK’s financial performance and to compare the company’s financial performance with the performance of other companies within the industry. Adjusted EBITDA should not be considered in isolation or as a substitute for net income or any other measure of financial performance presented in accordance with GAAP. This non-GAAP financial measure excludes some, but not all, items that affect net income. Additionally, this calculation may not be comparable with similarly titled measures of other companies. A reconciliation of net income to adjusted EBITDA is included in the tables available on ONEOK’s website. At ONEOK (NYSE: OKE), we deliver energy products and services vital to an advancing world.
