Acquisition includes interests across 377 producing wells, approximately 150 BOE/day of current net production, and 27 additional wells in process, with $48 million of proved PV-10 and an illustrative 21% unlevered cash return at $75 WTI 1

SPRING BRANCH, Texas, Aug. 27, 2026 (GLOBE NEWSWIRE) -- Callan JMB Inc. (NASDAQ: CJMB) (“Callan JMB” or the “Company”) a diversified company focused on logistics, emergency preparedness and critical infrastructure, today announced that, acting through its wholly owned subsidiary, Callan Power LLC, it has entered into a definitive Asset Purchase and Sale Agreement to acquire a non-operated working interest position in producing oil and gas properties in the Williston Basin of North Dakota and Montana from The Pfanenstiel Company, LLC for $12.5 million in cash, plus reimbursement of certain costs associated with wells currently in process. An independent reserve report prepared by Pinnacle Energy Services, LLC estimates the PV-10 (Present Value Cash Flows) attributable to the acquired interest at $48.1 million on a proved basis and $82.7 million on a total proved, probable and possible basis. The Company anticipates closing the transaction before October 1, 2026.

Transaction Highlights

Significant increase in diversified, oil-producing assets : Interests across 377 gross producing wells in five North Dakota and Montana counties, limiting reliance on the performance of any single wellbore, generating approximately 150 BOE/d 2 of current net production, approximately 85% weighted to crude oil.

Substantial upside in future drillable locations: Over 4 net wells on proved undeveloped acreage remain available for drilling and development.

Independently evaluated reserves: Estimated PV-10 of $48.1 million on proved reserves and $82.7 million on total proved, probable and possible reserves, based on an independent reserve report prepared by Pinnacle Energy Services, LLC. Net proved reserves attributable to the acquired interest total approximately 4.3 million BOE, approximately 79% weighted to crude oil, of which $9.7 million of PV-10 is attributable to proved developed reserves and $38.4 million to proved undeveloped locations.

Highly cash accretive: Approximately $2.5 million of annualized net operating cash flow at $75 WTI, representing an illustrative 21.2% unlevered cash return on the $12.5 million purchase price from currently producing wells alone.

Large acquisition of acreage: Approximately 3,000 net acres held by production with no lease-expiration exposure, delay-rental obligations, or drilling commitments.

Additional wells in process : Interests in 27 gross wells that are permitted, drilling, awaiting completion, or being completed, with the potential to contribute incremental production and cash flow as they are placed into production.

Non-operated structure: Callan Power will participate in its share of production, development capital, and cash flow without assuming direct responsibility for field operations, staffing, or production facilities.

“This acquisition will strengthen Callan Power’s energy footprint following the announced acquisition of Reger Oil assets and provide immediate exposure to producing energy assets with current cash flow, substantial diversification and additional development activity already underway,” said Wayne Williams, Chief Executive Officer of Callan JMB. “With a projected $2.5 million in illustrative annualized net operating cash flow at $75 WTI, an independently estimated proved PV-10 of approximately $48 million and a total 3P PV-10 of approximately $83 million, we believe this is a compelling transaction. Just as importantly, the non-operated structure allows us to participate in the economics of a diversified portfolio of producing assets while experienced operators manage field operations.”

Michael Reger, soon-to-be President of Callan Power and a longtime energy executive who founded Northern Oil and Gas, brings extensive experience with the non-operated upstream model that underpins the acquired asset portfolio.

“This is exactly the kind of asset we want to own,” said Michael Reger. “It is producing on day one, every acre is held by production, and the cash flow is spread across 377 wells operated by some of the leading operators in the Williston Basin rather than concentrated in a handful of wellbores. We are acquiring current production at a price that provides an attractive return based on the producing wells alone, with 27 additional wells currently in process and approximately ten years of future drilling inventory behind them. The non-operated strategy has been a central part of my energy career for two decades, and we believe this position provides a strong foundation from which to build.”

Forward-Looking Statements

This press release contains “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, and the Private Securities Litigation Reform Act of 1995. Forward-looking statements include, without limitation, statements regarding the expected closing of the acquisition and the timing thereof; estimated production volumes, net acreage, well counts and reserves; estimated revenue, cash flow, operating costs, taxes and returns, including the illustrative figures set forth above; the expected timing, cost and productivity of the wells in process; commodity price assumptions; the Company’s ability to obtain financing for the acquisition; and the Company’s strategy, plans and objectives. These statements are based on management’s current expectations and assumptions and are subject to known and unknown risks and uncertainties that could cause actual results to differ materially. Such risks include, without limitation: the failure to satisfy the conditions to closing, or the failure of the acquisition to close at all; volatility in oil, natural gas and natural gas liquids prices and in regional differentials; the Company’s status as a non-operator, under which it does not control the timing, cost or manner of drilling, completion or operations, including with respect to the 27 wells in process; risks that actual production, decline rates, operating costs and capital costs differ materially from the assumptions used; the inherent uncertainty of reserve estimates, including the risk that estimated reserves and PV-10 are not realized, that reserve estimates prepared using forward strip pricing differ materially from those prepared using SEC pricing, and that reserves attributable to undeveloped locations are never developed; title, environmental, regulatory, litigation and permitting risks, including pending litigation relating to certain of the acquired wellbores; the Company’s ability to obtain required financing and bonding on acceptable terms or at all; the Company’s limited operating history in the oil and gas industry and the risks of entering a new line of business; the risk that the acquisition is not accretive; and the other risk factors described in the Company’s filings with the Securities and Exchange Commission, including its Annual Report on Form 10-K and subsequent periodic reports. Any forward-looking statement speaks only as of the date on which it is made, and the Company undertakes no obligation to update or revise any forward-looking statement, whether as a result of new information, future events or otherwise, except as required by law. The illustrative cash flow figures presented above are not projections, forecasts or guidance of future results. They are arithmetic illustrations derived from the stated assumptions and are presented solely to describe the sensitivity of the acquired assets to commodity prices. They assume production is held flat and therefore do not reflect the natural production decline that will occur. Net operating cash flow is a non-GAAP financial measure and is not a substitute for, and should not be considered in isolation from, net income, operating income, cash flow from operating activities or any other measure calculated in accordance with generally accepted accounting principles. Because these amounts are forward-looking and depend on future commodity prices, volumes and costs, the Company is unable to reconcile them to the most directly comparable GAAP measure without unreasonable effort.
