Spire Reports FY24 First Quarter Results

ST. LOUIS (Feb. 1, 2024) - Spire Inc. (NYSE: SR) today reported results for its fiscal 2024 first quarter ended December 31, including:

•  Net income of $85.1 million ($1.52 per share) compared to $91.0 million ($1.66 per share) in the prior year

•  Net economic earnings* (NEE) of $82.7 million ($1.47 per share) compared to $85.1 million ($1.55 per share) a year ago

•  Affirmed fiscal 2024 NEE expectation of $4.25–$4.45 per share

“During the first quarter, we delivered solid operational and financial results driven by growth in the Gas Utility segment. When extreme cold weather recently covered our entire service territory, our dedicated employees demonstrated their strong commitment to delivering safe, reliable and affordable energy to customers,” said Steve Lindsey, president and chief executive officer of Spire. “We remain focused on execution of our growth strategy and operational excellence in our businesses. In January, we enhanced our leadership team with the addition of Scott Doyle as chief operating officer and further bolstered reliability for customers with the acquisition of the MoGas and Omega pipeline businesses.”

*Non-GAAP, see “Net Economic Earnings and Reconciliation to GAAP.”

For fiscal 2024 first quarter, Spire reported consolidated net income of $85.1million ($1.52 per diluted share) compared to prior-year net income of $91.0 million ($1.66 per diluted share). Net economic earnings were $82.7million ($1.47 per share) compared to earnings of $85.1million ($1.55 per share) last year. The results reflect growth at the Gas Utility segment, which was more than offset by a return to more normal market conditions for the Gas Marketing and Midstream segments compared to very favorable market conditions in the prior year, as discussed below.

NEE excludes from net income, as applicable, the 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 impairments and certain regulatory, legislative, or GAAP standard-setting actions.

Gas Utility

The Gas Utility segment includes the regulated distribution operations of five gas utilities across Alabama, Mississippi and Missouri. For fiscal 2024 first quarter, Gas Utility reported NEE of $75.8 million, up from $62.9 million in the prior year. The higher earnings reflect a strong performance across all utilities. 

Contribution margin increased $22.8 million, mainly due to the benefit of rates implemented in late December 2022 and early January 2023 at Spire Missouri and Spire Alabama, respectively, which was partially offset by lower commercial and industrial customer usage.

Operation and maintenance expense of $116.7 million was $3.2 million lower than a year ago due to lower employee-related costs, partially offset by higher insurance expense.

Depreciation and amortization expense increased $4.5 million from last year, reflecting increased capital investment. Interest expense also increased $6.9 million to $39.0 million primarily due to higher rates. The benefit of carrying cost credits increased $1.7 million quarter over quarter.

Gas Marketing

The Gas Marketing segment reflects the results of Spire Marketing, which provides natural gas marketing services throughout the United States. First quarter NEE was $7.2 million, compared to $25.7 million in the prior year. The quarter-over-quarter decrease is due to a return to more normal market conditions in the current year compared to very favorable market conditions in the prior year that allowed the business to leverage regional basis differentials to optimize storage and transportation positions.

Midstream

NEE for the Midstream segment, which includes Spire STL Pipeline, Spire Storage West and Spire Storage Salt Plains, was $2.4 million compared to $3.8 million in the year-ago period. Similar to our Gas Marketing segment, the quarter-over-quarter decrease is primarily due to a return to more normal market conditions in the current year compared to very favorable market conditions in the prior year that allowed the business to more effectively optimize storage operations and commitments.  

Other

Spire’s other activities reported a loss on an NEE basis of $2.7 million compared to $7.3 million a year ago, reflecting the settlement of an interest rate hedge in the current period, partially offset by higher corporate costs.

Guidance and Outlook

Spire continues to expect fiscal 2024 NEE to be in a range of $4.25–$4.45 per share. We remain confident in our ability to grow long-term NEE per share 5–7% driven by expected 7–8% annual utility rate base growth, reflecting our robust capital investment plan.

Our 10-year $7.2 billion capital investment target through fiscal 2033 is driven by increasing investment in infrastructure upgrades and new business in the Gas Utility segment. Expected capital expenditures for fiscal 2024 remain $765 million, which includes $100 million for the Spire Storage West expansion.

Forward-Looking Information and Non-GAAP Measures

This news release contains forward-looking statements within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended. Spire’s future operating results may be affected by various uncertainties and risk factors, many of which are beyond the Company’s control, including weather conditions, economic factors, the competitive environment, governmental and regulatory policy and action, and risks associated with acquisitions. More complete descriptions and listings of these uncertainties and risk factors can be found in the Company’s annual (Form 10-K) and quarterly (Form 10-Q) filings with the Securities and Exchange Commission. 

This news release includes the non-GAAP financial measures of “net economic earnings,” “net economic earnings per share,” and “contribution margin.” Management also uses these non-GAAP measures internally when evaluating the Company’s performance and results of operations. Net economic earnings exclude from net income, as applicable, the 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 impairments and other non-recurring or unusual items such as certain regulatory, legislative, or GAAP standard-setting actions. 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 the 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. Contribution margin adjusts revenues to remove the costs that are directly passed on to customers and collected through revenues, which are the wholesale cost of natural gas and gross receipts taxes. These internal non-GAAP operating metrics should not be considered as an alternative to, or more meaningful than, GAAP measures such as operating income, net income, or earnings per share.
