INVESTOR INFORMATION

Non-GAAP (Generally Accepted Accounting Principles) Financial Measures

ONEOK and ONEOK Partners have disclosed in this annual report adjusted EBITDA, cash flow available for dividends, free cash flow and dividend coverage ratio, and ONEOK Partners distributable cash flow and distribution coverage ratio, which are non-GAAP financial metrics, used to measure the company’s financial performance and are defined as follows:

  • Adjusted EBITDA is defined as net income adjusted for interest expense, net of capitalized interest, depreciation and amortization, impairment charges, income taxes and allowance for equity funds used during construction and certain other noncash items;
  • Cash flow available for dividends is defined as cash distributions declared from ONEOK’s ownership in ONEOK Partners adjusted for ONEOK’s standalone interest expense, corporate expenses, excluding certain noncash items, payments related to released contracts from ONEOK’s former energy services business, capital expenditures and equity compensation reimbursed by ONEOK Partners;
  • Free cash flow is defined as cash flow available for dividends, computed as described above, less ONEOK’s dividends declared;
  • Dividend coverage ratio is defined as cash flow available for dividends divided by the dividends declared for the period;
  • Distributable cash flow is defined as ONEOK Partners adjusted EBITDA, computed as described above, less interest expense, maintenance capital expenditures and equity earnings from investments, adjusted for cash distributions received and certain other items; and
  • Distribution coverage ratio is defined as ONEOK Partners distributable cash flow to limited partners per limited partner unit divided by the distribution declared per limited partner unit for the period.

These non-GAAP financial measures described above are useful to investors because they are used by many companies in the industry as a measurement of financial performance and are commonly employed by financial analysts and others to evaluate our financial performance and to compare our financial performance with the performance of other companies within our industry. ONEOK cash flow available for dividends, free cash flow and dividend coverage ratio, and ONEOK Partners distributable cash flow and distribution coverage ratio, 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.

These non-GAAP financial measures exclude some, but not all, items that affect net income. Additionally, these calculations may not be comparable with similarly titled measures of other companies. Reconciliations of adjusted EBITDA, cash flow available for dividends and free cash flow to net income are included in the tables.

Forward-Looking StatEments

Some of the statements contained and incorporated in this annual report are forward-looking statements as defined under federal securities laws. The forward-looking statements relate to our anticipated financial performance (including projected operating income, net income, capital expenditures, cash flow and projected levels of dividends and distributions), liquidity, management’s plans and objectives for our future growth projects and other future operations (including plans to construct additional natural gas and natural gas liquids pipelines and processing facilities and related cost estimates), our business prospects, the outcome of regulatory and legal proceedings, market conditions, statements about the benefits of the Merger Transaction involving ONEOK and ONEOK Partners and other matters. We make these forward-looking statements in reliance on the safe harbor protections provided under federal securities legislation and other applicable laws. The following discussion is intended to identify important factors that could cause future outcomes to differ materially from those set forth in the forward-looking statements.

Forward-looking statements include the items identified in the preceding paragraph, the information concerning possible or assumed future results of our operations and other statements contained or incorporated in this annual report identified by words such as “anticipate,” “estimate,” “expect,” “project,” “intend,” “plan,” “believe,” “should,” “goal,” “forecast,” “guidance,” “could,” “may,” “continue,” “might,” “potential,” “scheduled” and other words and terms of similar meaning.

One should not place undue reliance on forward-looking statements. Known and unknown risks, uncertainties and other factors may cause our actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by forward-looking statements.

  • the risk that a condition to closing of the Merger Transaction may not be satisfied;
  • the timing to consummate the Merger Transaction;
  • the risk that the cost savings, tax benefits and any other synergies from the Merger Transaction may not be fully realized or may take longer to realize than expected;

  • changes in demand for the use of natural gas, NGLs and crude oil because of market conditions caused by concerns about climate change;

  • our indebtedness could make us vulnerable to general adverse economic and industry conditions, limit our ability to borrow additional funds and/or place us at competitive disadvantages compared with our competitors that have less debt, or have other adverse consequences;
  • actions by rating agencies concerning the credit ratings of ONEOK and ONEOK Partners;
  • the results of administrative proceedings and litigation, regulatory actions, rule changes and receipt of expected clearances involving any local, state or federal regulatory body, including the FERC, the National Transportation Safety Board, the PHMSA, the EPA and CFTC;

  • the efficiency of our plants in processing natural gas and extracting and fractionating NGLs;
