Current report

On July 27, 2025, Spire entered into an agreement with Piedmont Natural Gas, a wholly-owned Subsidiary of Duke Energy, to acquire its Tennessee natural gas business that serves more than 200,000 customers in the Nashville area (the “Transaction”). The strategic rationale for the Company is described below:

Current report

We expect the Transaction to allow Spire to significantly expand its regulated utility footprint in high-quality jurisdictions and significantly increase the scale of its regulated business while delivering on Spire’s commitment to growth and creating long-term shareholder value.

Current report

We expect the Transaction to provide robust growth driven by customer additions and system integrity investments, aligned with Spire’s investment strategy. These long-term investments are expected to be supported by Tennessee’s constructive regulatory environment support of natural gas.

Current report

We expect the Transaction to support Spire’s long-term adjusted earnings per share growth expectations and provide meaningful investment opportunities. The acquisition is expected to generate incremental cash flow to support investment in the business, shareholder returns and dividend growth.

Current report

The stated purchase price of the Transaction is $2.48 billion subject to adjustment, including adjustments based on net working capital, regulatory assets and liabilities and capital expenditures at closing. The Transaction is supported by a fully committed bridge facility with BMO Capital Markets Corp. for the entire purchase price.

Current report

We expect permanent financing of the acquisition will be funded through a balance mix of debt, equity and hybrid securities. Spire is also evaluating the sale of non-utility assets, such as natural gas storage facilities, as a potential source of funds.

Current report

The Transaction is expected to close in the first quarter of calendar 2026, subject to customary closing conditions, including the approval of the Tennessee Public Utility Commission and the expiration or termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act.

Current report

For the quarter ended June 30, 2025, Gas Utility net loss and adjusted loss were lower than the corresponding prior-year period by $4.4 and $1.0, respectively. The quarterly change in net income was driven by the $3.8 and $1.6 growth of Spire Missouri and Spire Alabama, respectively. The variance differential between the $4.4 net loss and the $1.0 adjusted loss performance was primarily the result of the prior-year quarter GAAP result including $3.3 (after-tax) charges related to the Company’s customer affordability initiative that was excluded from adjusted earnings.

Current report

Contribution margin increased $4.2 versus the prior-year quarter. Contribution margin benefited from the $8.8 Spire Missouri ISRS growth and the $1.1 increase in off-system sales at both Spire Missouri and Spire Alabama. These favorable impacts more than offset the $2.2 net unfavorable impact of weather-mitigated volume margins at Spire Missouri. The quarter’s results were also unfavorably impacted by a $1.0 lower benefit attributable to Spire Alabama’s Cost Control Measure (CCM).

Current report

Including $21.4 (after-tax) favorable mark-to-market activity, net income increased $25.7. Adjusted income, after removing the mark-to-market activity, increased $4.3. Gas Marketing’s business portfolio was well-positioned to create value.

Current report

Contribution margin increased $33.6 versus the prior-year quarter, reflecting the $28.5 (pre-tax) favorable mark-to-market activity. Excluding this impact, contribution margin increased $5.1. As noted above, Gas Marketing’s business portfolio was well-positioned to create value.

Current report

O&M expenses for the current-year quarter increased $1.3 versus the prior-year quarter. Excluding the impact of the NSC Transfer, O&M expenses were $0.2 higher than the prior-year quarter. After excluding the $3.5 prior year charge relating to the Company’s customer affordability initiative, O&M expenses were $3.7 higher than the prior-year quarter. Lower bad debt expense was more than offset by higher field operations and employee costs.

Current report

Reported other income increased by $0.9 versus the prior-year quarter, but decreased $0.2 after removing the impact of the NSC Transfer. Favorable mark-to-market unrealized gains on non-qualified benefit trusts was offset by a $1.5 decrease in gas carrying cost credits. Interest expense decreased $1.0, reflecting lower average short-term interest rates in the current year more than offsetting the incremental interest expense related to higher average debt levels.

Current report

Resulting net loss for the quarter ended June 30, 2025 decreased $3.8 versus the prior-year quarter.

Current report

Contribution margin was slightly below the prior-year quarter, as a lower CCM benefit was mostly offset by off-system sales and weather-mitigated volumetric impacts.

Current report

Depreciation and amortization expenses decreased $0.6 versus the comparable prior-year period as change in rates offset the impact of ongoing capital investments.

Current report

Taxes, other than income taxes decreased $0.3 driven by lower pass-through gross receipts taxes.

Current report

Including $4.9 (after-tax) favorable mark-to-market activity, net income increased $3.5. The $1.4 year-over-year decrease in adjusted earnings reflects higher storage and transportation fees in the current year.

Current report

Reported O&M expenses for the nine months ended June 30, 2025 increased $1.8 versus the corresponding prior-year period. Excluding the NSC Transfer impact, O&M expense decreased $0.8. After excluding the $3.5 prior-year charge relating to the Company’s customer affordability initiative, O&M expenses were $2.7 higher than the corresponding prior year period. Higher employee-related costs were only partly mitigated by lower bad debt expense costs and lower

Current report

Depreciation and amortization expenses decreased $1.0 versus the comparable prior-year period as changes in rates offset the impact of ongoing capital investments. Taxes, other than income taxes decreased $3.1, driven by lower pass-through gross receipts taxes.

Previous report

For the quarter ended March 31, 2025, Gas Utility net income and adjusted earnings were higher than the corresponding prior-year period by $6.9 and $7.2, respectively. The quarterly change in net income was driven by the $7.7 growth of Spire Missouri, which offset slightly lower performance by Spire Alabama and Spire EnergySouth.

Previous report

Contribution margin increased $14.7 versus the prior-year quarter. Contribution margin benefited from the $8.7 Spire Missouri ISRS growth and $6.5 favorable volumetric impact of Spire Missouri. The current year period also benefited from Spire Alabama’s annual rate update, which includes the benefit of the reversal of the $4.1 customer refund provision that was recorded in the first quarter of the current fiscal year. These favorable impacts more than offset the $7.1 net unfavorable impact of weather-mitigated volume margins at Spire Alabama.

Previous report

Including $12.5 (after-tax) unfavorable mark-to-market activity, net income decreased $13.2. The $0.7 quarter-over-quarter decrease in adjusted earnings primarily reflects reduced volatility in regional basis differentials combined with higher transportation and storage fees.

Previous report

O&M expenses for the current-year quarter decreased $0.8 versus the prior-year quarter. Excluding the impact of the NSC Transfer, O&M expenses were $1.9 lower than the prior-year quarter, as lower expense levels for A&G and support functions resulting from customer affordability initiatives implemented last year were partially offset by bad debt expense.

Previous report

Contribution margin was slightly below the prior-year quarter, as favorable RSE adjustments, including the benefit of the reversal of the $4.1 customer refund provision that was recorded in the first quarter of the current fiscal year, and higher off-system sales were offset by the net unfavorable impact of weather-mitigated volume margins.

Previous report

Net income and net adjusted earnings decreased $22.2 and $5.7, respectively, versus the prior-year period. The decrease in adjusted earnings primarily reflects reduced volatility in regional basis differentials combined with higher transportation and storage fees.

Previous report

O&M expenses for the six months ended March 31, 2025 increased $0.5 versus the corresponding prior-year period. Excluding the NSC Transfer impact, O&M expense decreased $1.0. Lower A&G and support function costs resulting from customer affordability initiatives implemented last year more than offset higher bad debt expense.
Reworded paragraphs (53)

Previous wording

The decrease in interest expense reflects lower effective interest rates on long-term and short-term debt that more than offset higher average levels of debt in the current year. Weighted-average short-term interest rates were 4.5% in the current-year quarter versus 5.8% in the prior-year quarter.

Current wording

The increase in interest expense reflects interest on higher average levels of debt in the current year that more than offset lower effective interest rates on short-term debt. Weighted-average short-term interest rates were 4.5% in the current-year quarter versus 5.6% in the prior-year quarter.

Previous wording

Other income decreased $4.3 versus the prior-year quarter, $5.2 after removing the $0.9 benefit attributable to the Postretirement Non-Service Costs Transfer (“NSC Transfer”), which has no impact on net income. The principal drivers of the decline were a decline of gas carrying cost credits at Spire Missouri, and unfavorable mark-to-market unrealized losses on non-qualified benefit trusts.

Current wording

Other income increased $2.2 versus the prior-year quarter, $1.3 after removing the $0.9 benefit attributable to the Postretirement Non-Service Costs Transfer (“NSC Transfer”), which has no impact on net income. The principal driver of the increase was favorable mark-to-market unrealized gains on non-qualified benefit trusts that more than offset a decline of gas carrying cost credits at Spire Missouri.

Previous wording

The primary driver of the current year decrease in revenue was the $137.0 impact of lower gas cost recoveries across all utilities, driven principally by lower PGA rates at Spire Missouri. These reductions were only partly offset by higher volumetric usage, current year ISRS billings and favorable net RSE adjustments at Spire Alabama.

Current wording

The primary driver of the current year decrease in revenue was the $31.2 impact of lower gas cost recoveries across all utilities, driven principally by lower PGA recovery and volume, including weather mitigation, at Spire Missouri. These reductions were only partly offset by higher current year ISRS billings and off-system sales.

Previous wording

Reported operation and maintenance (“O&M”) expenses for the three months ended March 31, 2025 were $1.2 higher than the prior-year quarter. Excluding the impact of the NSC Transfer, O&M expenses were $0.2 higher than the prior-year quarter, as lower expense levels for Administrative and General (“A&G”) and support functions resulting from customer affordability initiatives implemented last year were more than offset by higher field operations costs and bad debt expense.

Current wording

Reported operation and maintenance (“O&M”) expenses for the three months ended June 30, 2025 were $0.3 lower than the prior-year quarter. Excluding the impact of the NSC Transfer, O&M expenses were $1.2 lower than the prior-year quarter. After excluding the $4.4 relating to the Company’s customer affordability initiative in the prior-year, O&M expenses were $3.2 higher than the prior-year quarter. Lower bad debt expense and insurance claims were more than offset by higher outside service expenses and employee costs.

Previous wording

Taxes, other than income taxes, decreased $5.6, primarily due to lower gross receipt taxes resulting from lower revenues. Depreciation and amortization expenses for the quarter ended March 31, 2025 were $4.1 higher than the same period in the prior year primarily driven by continued infrastructure capital expenditures across all the Utilities. Interest expense decreased $4.5, with both Spire Missouri and Spire Alabama benefiting from lower average short-term interest rates in the current year. The benefit of gas carrying cost credits at Spire Missouri, included in other income, decreased $3.2 versus the corresponding prior-year quarter.

Taxes, other than income taxes, decreased $1.2, primarily due to $2.8 lower gross receipt taxes resulting from lower revenues more than offsetting an increase in property tax. Depreciation and amortization expenses for the quarter ended June 30, 2025 were $3.3 higher than the same period in the prior year primarily driven by continued infrastructure capital expenditures across all the Utilities. Interest expense decreased $1.7, with both Spire Missouri and Spire Alabama benefiting mostly from lower average short-term and long-term interest rates partially offset by higher balances in the current year. The benefit of gas carrying cost credits at Spire Missouri, included in other income, decreased $1.5 versus the corresponding prior-year quarter, but was more than offset by unrealized gains in non-qualified benefit trusts.

Previous wording

Contribution margin decreased $17.0 versus the prior-year quarter, reflecting the $16.7 (pre-tax) unfavorable mark-to-market activity. Excluding this impact, contribution margin decreased $0.3, reflecting the unfavorable drivers noted above. O&M expenses were slightly higher than prior-year levels, the result of higher spend on outside services in the current year.

Current wording

The Company’s other activities generated a $7.4 loss in the three months ended June 30, 2025, $1.0 less versus prior-year performance. Gains from non-qualified benefit and insurance trusts more than offset higher interest expense in the current year.

Previous wording

Revenues for the quarter ended March 31, 2025 were $94.9 lower than the comparable prior-year period. Lower PGA gas costs reduced gas cost recoveries by $113.0. This reduced revenue driver also resulted in reduced gross receipts taxes of $4.1. These negative impacts were only partly offset by $8.7 incremental ISRS revenues, $7.3 attributable to higher off-system sales and favorable volume impacts of $6.5 in the current-year quarter.

Current wording

Revenues for the quarter ended June 30, 2025 were $18.7 lower than the comparable prior-year period. Lower PGA gas cost recovery reduced revenues by $27.0.

Previous wording

The Company’s other activities generated a $22.3 loss in the six months ended March 31, 2025. The major contributor to this variance was the $8.2 pre-tax ($6.3 after-tax) interest rate swap gain in the prior year that did not repeat. The remaining variance was mostly a result of higher interest expense in the current year that was only partly offset by lower corporate expenses.

Current wording

The Company’s other activities generated a $29.7 loss in the nine months ended June 30, 2025, $7.9 higher than the prior year. The major contributor to this variance was the $8.2 pre-tax ($6.3 after-tax) interest rate swap gain in the prior year that did not repeat. The remaining variance was mostly a result of higher interest expense in the current year that was offset by lower corporate expenses.

Previous wording

Revenues for the six months ended March 31, 2025 were $172.8 lower than the comparable prior-year period. Lower unit gas costs reduced gas cost recoveries by $198.1. This reduced revenue driver also resulted in reduced gross receipts taxes of $7.1. These negative impacts were only partly offset by $15.7 incremental ISRS revenues, $13.1 attributable to higher off-system sales in the current-year, and increased weather-mitigated customer usage of $3.1 versus the prior-year period.

Current wording

Revenues for the nine months ended June 30, 2025 were $191.5 lower than the comparable prior-year period. Lower PGA rates reduced gas cost recoveries by $225.1.
