Insights

Energy M&A and Capital Structure Analyst

NOG closes a $1.2 billion Utica joint acquisition and secures a larger credit facility to support it.

Northern Oil and Gas has closed its joint purchase of Ohio Utica Shale upstream and midstream assets from Antero, with total cash consideration of approximately $800 million for Upstream Assets and $400 million for Midstream Assets shared with Infinity Natural Resources. Amendments shifted ownership so INR now holds 60% and Northern 40% of each asset package, with Northern’s unadjusted purchase price set at $320 million upstream and $160 million midstream.

The company paid a $464.5 million closing amount, including a $58.8 million deposit, funded through cash on hand, operating free cash flow and borrowings under its reserves-based lending facility. In tandem, Northern negotiated a credit agreement amendment increasing its borrowing base to $1.975 billion from $1.8 billion and its elected commitment to $1.8 billion from $1.6 billion, while keeping other terms largely unchanged for the facility due 2030.

Strategically, this filing highlights a scale expansion in a core shale basin, backed by additional liquidity from an 18-lender syndicate. Actual financial impact will depend on production performance of the acquired properties, commodity prices and how Northern manages leverage under the enlarged revolving credit facility in future reporting periods.

FAQ

AI-generated questions and answers. How Rhea-AI works. Not financial advice.

What acquisition did Northern Oil and Gas (NOG) close in the Ohio Utica Shale?

Northern closed a joint acquisition of upstream and midstream assets in the Ohio Utica Shale from Antero entities. The combined cash purchase price was approximately $800 million for Upstream Assets and $400 million for Midstream Assets, shared with Infinity Natural Resources.

What ownership interest did NOG acquire in the Antero Utica assets?

NOG acquired a 40% interest in both the Upstream Assets and Midstream Assets, while Infinity Natural Resources holds 60%. This revised split comes from amendments to the original purchase agreements signed on February 22, 2026, adjusting the initial 49%/51% structure.

How much did NOG pay at closing for its Ohio Utica acquisition stake?

NOG’s closing payment was $464.5 million in cash, including a $58.8 million deposit paid at signing. The payment reflects preliminary and customary purchase price adjustments and remains subject to post-closing settlements between Northern and Antero.

How did Northern Oil and Gas fund the Ohio Utica acquisition?

Northern funded the $464.5 million closing payment using cash on hand, operating free cash flow and borrowings from its revolving credit facility. This blended funding approach combines internal cash generation with additional draws on its reserves-based lending facility.

What changes were made to NOG’s revolving credit facility in 2026?

An amendment increased the borrowing base to $1.975 billion from $1.8 billion and raised the elected commitment amount to $1.8 billion from $1.6 billion. The facility, due 2030, otherwise retains substantially unchanged terms with an 18-lender syndicate.

Why did NOG and Infinity Natural Resources amend their Antero purchase agreements?

The amendments shifted the ownership interests so Infinity Natural Resources now acquires 60% and NOG 40% of both Upstream and Midstream Assets. Correspondingly, NOG’s unadjusted purchase prices are $320 million upstream and $160 million midstream, altering the initial 49% share.

SAFE HARBOR

This press release contains forward-looking statements regarding future events and future results that are subject to the safe harbors created under the Securities Act of 1933, as amended, and the Securities Exchange Act of 1934, as amended. All statements other than statements of historical facts included in this release regarding NOG’s financial position, business strategy, plans and objectives of management for future operations, industry conditions, capital expenditures, production, cash flow, hedging and other matters are forward-looking statements. When used in this release, forward-looking statements are generally accompanied by terms or phrases such as “estimate,” “guidance,” “project,” “predict,” “believe,” “expect,” “continue,” “anticipate,” “target,” “could,” “plan,” “intend,” “seek,” “goal,” “will,” “should,” “may” or other words and similar expressions that convey the uncertainty of future events or outcomes. Items contemplating or making assumptions about actual or potential future production, sales, market size, collaborations, cash flows, and trends or operating results also constitute such forward-looking statements.

Forward-looking statements involve inherent risks and uncertainties, and important factors (many of which are beyond NOG’s control) that could cause actual results to differ materially from those set forth in the forward-looking statements, including the following: changes in crude oil and natural gas prices, the pace of drilling and completions activity on NOG’s properties and properties pending acquisition, the effects of the COVID-19 pandemic and related economic slowdown, NOG’s ability to acquire additional development opportunities, integration and benefits of property acquisitions, or the effects of such acquisitions on Northern’s cash position and levels of indebtedness, changes in NOG’s reserves estimates or the value thereof, general economic or industry conditions, nationally and/or in the communities in which NOG conducts business, changes in the interest rate environment, legislation or regulatory requirements, conditions of the securities markets, risks and uncertainties related to the closing of recent acquisition transactions (including the transactions described herein), NOG’s ability to raise or access capital, changes in accounting principles, policies or guidelines, financial or political instability, acts of war or terrorism, and other economic, competitive, governmental, regulatory and technical factors affecting NOG’s operations, products, services and prices. Additional information concerning potential factors that could affect future results is included in the section entitled “Item 1A. Risk Factors” and other sections of NOG’s most recent Annual Report on Form 10-K and subsequently filed Quarterly Reports on Form 10-Q, as updated from time to time in amendments and subsequent reports filed with the SEC, which describe factors that could cause NOG’s actual results to differ from those set forth in the forward-looking statements.

NOG has based these forward-looking statements on its current expectations and assumptions about future events. While management considers these expectations and assumptions to be reasonable, they are inherently subject to significant business, economic, competitive, regulatory and other risks, contingencies and uncertainties, most of which are difficult to predict and many of which are beyond NOG’s control. Accordingly, results actually achieved may differ materially from expected results described in these statements. NOG does not undertake, and specifically disclaims, any obligation to update any forward-looking statements, except as may be required by the federal securities laws.
