Callan JMB Inc. has named Michael Reger president of its newly formed oil and gas unit, Callan Power LLC, a wholly owned subsidiary of the company.
Reger will oversee Callan Power’s business strategy, commercial relationships, and the development of oil and gas assets, the company said on Monday. He will also lead planned manufacturing operations in Alabama, where the subsidiary intends to produce power and distribution transformers, mobile substations, and advanced power cables using automated, vertically integrated processes.
His compensation will consist entirely of equity, with no cash salary provided. The appointment is contingent on the closing of Callan JMB’s previously announced acquisition of oil and gas assets from Reger Oil, Inc., a company he founded.
Callan Power will be headquartered at the Atlas Complex in Marion, Alabama, with additional manufacturing operations planned at a facility owned by Alabama State University in Brewton. The subsidiary aims to supply equipment for domestic energy infrastructure, including transformers for renewable energy applications and battery energy-storage systems.
Reger previously served as chairman emeritus of Northern Oil and Gas, Inc., a company he founded in 2006. During his tenure, Northern achieved production growth exceeding 40,000 barrels of oil equivalent per day and completed a $650 million recapitalization alongside approximately $850 million in acquisitions between 2018 and 2019. As of August 21, 2026, Northern Oil and Gas had a market capitalization of roughly $2.9 billion.
Coldchain Technology Services LLC, which Reger also founded in 2009, will continue to manage power-generation assets supporting healthcare organizations and government agencies.
