Natural Gas 01-Jul-2026

Spire finalized the $650 million sale of its gas storage business to I Squared Capital, strengthening finances and sharpening utility focus.

Spire Inc. has successfully finalized the sale of its natural gas storage operations located in Wyoming and Oklahoma to global infrastructure investment firm I Squared Capital. The transaction officially closed on June 30, 2026, with a total value of $650 million, marking a significant strategic milestone for the company as it strengthens its emphasis on regulated utility operations.

Under the terms of the agreement, Spire received an immediate cash payment of $600 million upon closing. The remaining $50 million will be paid as a fixed, non-contingent deferred installment during the company's fiscal year 2027. The structured payment arrangement provides Spire with both immediate liquidity and additional future financial support while completing the transition of ownership.

Following the acquisition, the former Spire Storage business has been incorporated into Bear River Midstream LLC, a newly established portfolio company under I Squared Capital. Employees previously associated with Spire Storage, along with existing customers, will transition seamlessly to Bear River Midstream, ensuring continuity of operations and customer service without disruption.

The proceeds generated from the divestiture will play an important role in financing Spire's previously completed acquisition of the Piedmont Natural Gas Tennessee business, which was finalized on March 31, 2026. By reallocating capital from non-core assets into regulated utility operations, Spire continues to execute its long-term strategy of focusing on businesses that offer more stable earnings and predictable growth opportunities.

Scott Doyle, President and Chief Executive Officer of Spire, described the completion of the transaction as an important achievement in the company's strategic transformation. He stated that the sale reinforces Spire's commitment to concentrating on its regulated natural gas utility business while improving its financial flexibility. Doyle also acknowledged the efforts of the employees who helped build and operate the storage platform over the years, expressing appreciation for their contributions to the company's overall success. According to him, the strengthened balance sheet resulting from the transaction positions Spire to continue delivering sustainable value to both customers and shareholders over the long term.

On the acquiring side, Bear River Midstream plans to further develop and expand the acquired storage platform. Scott Smith, Chief Executive Officer of Bear River Midstream and former President of Spire Storage, emphasized that the company intends to enhance operational performance while exploring expansion opportunities to meet rising demand for natural gas storage services across the Western and Mid-Continent regions of the United States. He also reassured customers that they would experience a smooth transition because the experienced operations and service teams responsible for managing the facilities will remain in place under the new ownership.

The acquired portfolio includes strategically located underground natural gas storage facilities in two key energy-producing regions. In southwestern Wyoming, the storage system comprises two storage fields with regulatory authorization to provide up to 55 billion cubic feet (Bcf) of working natural gas capacity. These facilities primarily serve customers throughout the western United States, providing flexibility for balancing seasonal demand and supporting regional energy reliability.

Additionally, the portfolio includes a storage facility located in north-central Oklahoma. This asset serves customers across the Mid-Continent and Midwestern United States through its direct connections to the Southern Star Pipeline and Oklahoma Gas Transmission systems. The Oklahoma facility has regulatory approval to provide up to 17 Bcf of working gas storage capacity, making it an important component of regional natural gas infrastructure.

The transaction also involved several prominent advisory firms. Greenhill, a Mizuho affiliate, served as the exclusive financial advisor to Spire throughout the sale process. Vinson & Elkins LLP acted as legal counsel for Spire, while Kirkland & Ellis provided legal advisory services to I Squared Capital during the acquisition.

The completion of this transaction represents a strategic realignment for both organizations. Spire strengthens its financial position and sharpens its focus on regulated utility operations, while I Squared Capital, through Bear River Midstream, gains ownership of a well-established natural gas storage platform with opportunities for operational improvements and future expansion to address growing regional energy storage requirements.

Impact on Products and Chemical Commodity Prices

The sale of Spire's natural gas storage assets to I Squared Capital is not expected to create an immediate impact on natural gas supply, as the facilities will continue operating under Bear River Midstream with the same workforce and customer base. However, the new ownership's plans to enhance operations and expand storage capacity could improve regional gas storage efficiency and supply flexibility over the medium to long term. Better storage infrastructure can help moderate seasonal price volatility by ensuring greater gas availability during peak demand periods. For chemical manufacturers tracked by ChemAnalyst, particularly producers of ammonia, methanol, hydrogen, urea, and other gas-intensive petrochemicals, stable natural gas availability supports more predictable production costs. In the near term, commodity prices are expected to remain largely unchanged because the transaction represents a change in ownership rather than production capacity. Over time, expanded storage capabilities may exert slight downward pressure on natural gas prices during demand spikes, indirectly supporting stable-to-soft pricing trends for gas-based chemical commodities.
