Callan JMB Inc. named Michael Reger president of Callan Power LLC, a wholly owned subsidiary formed to develop oil and gas assets and manufacture transformers and electrical equipment.
The appointment becomes effective upon completion of Callan JMB’s acquisition of assets from Reger Oil Inc., a company Reger founded in 2006. Reger previously led Northern Oil and Gas Inc., stepping down as CEO in 2019 after guiding the company through a $650 million recapitalization and approximately $850 million in acquisitions. At the time of his departure, Northern Oil and Gas reported production exceeding 40,000 barrels of oil equivalent per day and a market capitalization near $2.9 billion, based on trading prices from August 21, 2026.
Reger will receive no cash salary, with compensation structured entirely in equity. His responsibilities will include overseeing Callan Power’s business strategy, commercial relationships, and oil and gas asset development. The unit will also manage planned manufacturing operations in Alabama, including transformer production and advanced power solutions.
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 company intends to produce power and distribution transformers, pad-mounted and dry-type units, renewable energy transformers, mobile substations, battery energy-storage systems, and advanced power cables using automated, vertically integrated processes.
The new subsidiary builds on the operational experience of Coldchain Technology Services LLC, a Callan JMB affiliate that has managed power-generation assets for healthcare and government clients since 2009.
