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. Although 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. For a more complete description of these uncertainties and risk factors, see our Form 10-K for the fiscal year ended September 30, 2017 as filed with the Securities and Exchange Commission (SEC). This presentation also includes “net economic earnings,” “net economic earnings per share,” “contribution margin,” “adjusted EBITDA,” and “adjusted long-term capitalization,” non-GAAP measures used internally by management when evaluating the Company’s performance and results of

• perations. 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 include the revaluation

• f deferred tax assets and liabilities due to the federal Tax Cuts and Jobs Act and write-off of certain long-standing assets related to pension costs and

property sold as a result of disallowances in our Missouri rate proceedings. 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. 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. Adjusted EBITDA is earnings before interest, income taxes, depreciation and amortization, plus largely non-cash write-offs related to Missouri rate cases. 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 and of capitalization per balance sheet to adjusted long-term capitalization are also contained in the Appendix. Note: Years shown in this presentation are fiscal years ended September 30, unless otherwise indicated.

Delivering earnings growth YTD in FY18

• Net economic earnings1 (NEE) $210.3 million, up $32.2 million or 18%
• Gas Utility: NEE $208.1 million (+$20.8 million)

‒ Contribution margin2 +$18.3 million

• Higher demand (+$28.7 million) due to the return of normal weather
• Higher MO ISRS, customer growth and smaller RSE rate adjustment for Spire AL (+$5.8 million)
• Partially offset by new rate design at Missouri utilities ($9.8 million) and Alabama customer rate

reductions for tax reform ($9.7 million)

‒ O&M expense (net of write-offs) was $11.9 million higher, largely due to weather-driven increases in employee-related costs and bad debt expense

• Gas Marketing: NEE up $14.5 million on improved market conditions
• NEE per share of $4.30 reflects our May 2018 equity offering

– Reflect ~$70 million in cost savings from our transformative growth – Authorized 9.8% ROE, utility LT capital structure and $2.0B rate base – Aligns MO rate design: higher volumetric component and full residential weather normalization

Tax Cuts and Jobs Act

• We lowered customer rates for all utilities as a result of tax reform
• 1H financial results include impacts based on the available guidance, including

– Lowering our effective tax expense by $14.4 million, reflecting lower federal income taxes, net of amounts reflected in lower customer rates – GAAP results include revaluation of deferred taxes totaling $54 million (excluded from NEE)

• 2018 impact

– Cash flow will be reduced by ~$40 million annually due to lower customer rates – Interest deductibility will likely be retained due to our largely regulated mix and growing non-regulated EBITDA

Income tax expense

• Federal income tax expense now reflects the net TCJA impact based on current Treasury

– Regulatory certainty in key areas, including ROE and capital structure – Full residential weather normalization

• $8M increase in annual ISRS

revenues approved, eff. early Oct.

• We are assessing Spire’s regulatory

and legislative strategy going forward, and still strongly believe in the benefits of more progressive and timely rate review
