ST. LOUIS, June 30, 2026 /PRNewswire/ -- Spire Inc. (NYSE:SR) today announced it has completed the sale of its natural gas storage businesses in Wyoming and Oklahoma ("Spire Storage") to I Squared Capital, effective June 30, 2026, for $650 million.
Spire Storage employees and customers will become part of the new I Squared portfolio company Bear River Midstream LLC.
Total consideration for the transaction consists of $600 million in cash received at closing and a $50 million fixed, non-contingent deferred payment to be received in Spire's fiscal year 2027.
Proceeds from the transaction help fund Spire's previously completed acquisition of the Piedmont Natural Gas Tennessee business, which closed on March 31, 2026.
"This closing marks an important milestone for Spire as we continue to sharpen our focus on our core regulated utility business," said Scott Doyle, president and chief executive officer of Spire. "We're proud of the strong storage platform we built and are grateful to the employees who contributed to its success and the overall success of Spire. With this transaction complete, we've further enhanced our financial position and are well positioned to deliver long-term, sustainable value for our customers and shareholders."
"With Bear River Midstream, we plan to enhance operational capabilities and pursue expansion opportunities that meet the increasing market demand for energy storage across the Western and Mid-Continent regions," said Scott Smith, chief executive officer of Bear River Midstream and former president of Spire Storage. "We are happy to provide our customers a seamless transition because the same operations and service teams customers already know will continue working with the company."
The former Spire Storage business includes two storage fields in southwestern Wyoming and another in north central Oklahoma. In Wyoming, the natural gas storage assets are certificated to provide up to 55 Bcf of working gas capacity to customers primarily in the western United States. In Oklahoma, the storage asset markets in the midcontinent and midwestern United States and is connected to Southern Star Pipeline and Oklahoma Gas Transmission. That facility is authorized to provide up to 17 Bcf of working gas capacity.
Greenhill, a Mizuho affiliate, acted as exclusive financial advisor to Spire. Vinson & Elkins LLP served as Spire's legal counsel. Kirkland & Ellis served as I Squared's legal advisor.
