Summary
Spire Inc. has agreed to divest its natural gas storage assets in Wyoming and Oklahoma to I Squared Capital for $650 million, according to the announcement made on April 15, 2026. The transaction reflects ongoing consolidation and portfolio optimization within the natural gas infrastructure sector, with I Squared Capital positioning itself as an acquirer of midstream energy assets.
The deal was advised by two major legal firms: V&E and Kirkland & Ellis, both providing counsel on the transaction. This dual-advisor structure suggests a complex transaction with multiple parties requiring sophisticated legal guidance on energy asset sales, regulatory compliance, and infrastructure investment mechanics.
I Squared Capital's acquisition of these storage assets adds operational capacity in two strategically important natural gas storage regions. Wyoming and Oklahoma contain significant natural gas reserves and storage infrastructure critical to the broader U.S. energy supply chain. For Spire, the $650 million sale price represents monetization of non-core or underutilized storage assets, potentially freeing capital for deployment in other business segments or returning value to shareholders.
The transaction underscores continued institutional investor appetite for regulated or midstream energy infrastructure despite ongoing energy transition pressures. Natural gas storage assets, which provide critical seasonal and emergency supply cushioning for domestic energy markets, remain attractive to infrastructure investors seeking stable, cash-generative investments with long-term contracted revenue profiles.
