Forward-looking statements and use of non-GAAP measures This presentation contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Our forward- looking statements in this presentation speak only as of today, and we assume no duty to update them. Forward-looking statements are typically identified by words such as, but not limited to: “estimates,” “expects,” “anticipates,” “intends,” and similar expressions. A lthough our forward-looking statements are based on reasonable assumptions, various uncertainties and risk factors may cause future performance or results to be different than those anticipated. More complete descriptions and listings of these uncertainties and risk factors can be found in our annual (Form 10-K) and quarterly (Form 10-Q) filings with the Securities and Exchange Commission. This presentation also includes “net economic earnings,” “net economic earnings per share,” “contribution margin,” “adjusted EBI TDA,” and “adjusted long- term capitalization,” non - GAAP measures used internally by management when evaluating the Company’s performance and results of operations. Net economic earnings exclude from net income the after-tax impacts of fair-value accounting and timing adjustments associated with energy-related transactions, the impacts of acquisition, divestiture, and restructuring activities and the largely non-cash impacts of other non- recurring or unusual items such as certain regulatory, legislative, or GAAP standard-setting actions. In fiscal 2018, these items included the revaluation of deferred tax assets and liabilities due to the Tax Cuts and Jobs Act, and the write-off of certain long-standing assets as a result of disallowances in our Missouri rate proceedings. For fiscal 2019 this included ISRS rulings. The fair value and timing adjustments, which primarily impact the Gas Marketing segment, include net unrealized gains and losses on energy-related derivatives resulting from the current changes in fair value of financial and physical transactions prior to their completion and settlement, lower of cost or market inventory adjustments, and realized gains and losses on economic hedges prior to the sale of the physical commodity. Management believes that excluding these items provides a useful representation of the economic impact of actual settled transactions and overall results of ongoing operations by facilitating comparisons of year-over- year results. Contribution margin is defined as operating revenues less natural and propane gas costs and gross receipts tax expense, which are directly passed on to customers and collected through revenues. Adjusted long-term capitalization treats preferred stock as 50% debt and 50% equity, as rating agencies would treat preferred stock. EBITDA is earnings before interest, income taxes, depreciation and amortization. Management believes EBITDA provides a helpful additional measure of core results of Spire Storage. Adjusted EBITDA is earnings before interest, income taxes, depreciation and amortization, plus largely non-cash write-offs related to Missouri rate cases. These internal non-GAAP operating metrics should not be considered as an alternative to, or more meaningful than, GAAP measures such as operating income or net income. Reconciliations of net income to net economic earnings and of contribution margin to operating income are contained in our SEC filings and in the Appendix to this presentation. Reconciliations of adjusted EBITDA to net income, Storage EBITDA to net income and of adjusted long-term capitalization to capitalization per balance sheet are also contained in the Appendix.
