Northern Oil and Gas, Inc. (NYSE:NOG) ("NOG" or "Company") today announced the Company's first quarter results.

MANAGEMENT COMMENTS

"The current geopolitical environment is creating a dynamic environment for our business, and NOG is well-positioned to navigate it. We are seeing improved field level price realizations — particularly in the Williston — while strong hedging keeps us insulated from the seasonal weakness in natural gas prices. It is the longer-dated strip, however, that matters most, and improvements in 2027 and 2028 forward prices give us confidence in the durability of activity, M&A market liquidity, and our ability to compete for high-quality assets. Despite the current volatility, operator activity has remained relatively unchanged since the prior quarter, but we will continue to monitor operator plans and activity in the coming quarters," commented Nick O'Grady, Chief Executive Officer.

"Q1 was a banner quarter for our Ground Game, closing 41 transactions while keeping capital disciplined. Our leasing program — having added over 70 net locations in the past year — is building an underappreciated runway of future value that will continue to differentiate NOG from peers. With a strong balance sheet and robust free cash flow, we see the potential for meaningful growth ahead," added Adam Dirlam, President.

FIRST QUARTER FINANCIAL RESULTS

Oil and natural gas sales for the first quarter were $539.9 million. First quarter GAAP net loss was $522.8 million or $5.31 loss per basic and diluted share driven by a non-cash unrealized mark-to-market loss on derivatives of approximately $521.4 million and a non-cash impairment charge of $268.3 million. First quarter Adjusted Net Income was $74.7 million or $0.74 per adjusted diluted share. Adjusted EBITDA in the first quarter was $342.5 million, a 21% decrease from the first quarter of 2025, reflecting a 19% decrease in realized price on a Boe basis including settled commodity derivatives and the impact of a changing commodity mix. See "Non-GAAP Financial Measures" below.

PRODUCTION

First quarter 2026 production averaged 148,303 Boe per day, a 6% increase from the fourth quarter of 2025. Oil represented approximately 50% of total production in the first quarter at an average of 73,567 Bbls per day. NOG added 17.1 net wells to production during the first quarter, compared to 24.2 net wells added to production in the fourth quarter of 2025. The first quarter marked a lower point for well additions, in line with forecast, with the expectation of an acceleration of TILs through the balance of 2026. Well performance continues to be strong across all of NOG's basins. Appalachian volumes set another production record as our Appalachian joint development program continues to consistently deliver TILs according to plan.

PRICING

During the first quarter, NOG's unhedged net realized oil price was $66.32 per Bbl. The Company's average differential to WTI prices was $5.85, a 1% increase from the first quarter of 2025. NOG's unhedged net realized gas price in the first quarter was $2.50 per Mcf, representing a 72% realization compared with Henry Hub pricing. Natural gas realizations continue to be pressured due to lack of takeaway capacity in the Permian Basin.

HEDGING

In the first quarter, the Company recorded a non-cash unrealized mark-to-market loss on derivatives of approximately $521.4 million, driven by changes to the value of the Company's derivatives portfolio. Realized hedge losses were $17.6 million as gains on the Company's natural gas hedges were more than offset by losses on the Company's crude oil hedges.

OPERATING COSTS

Lease operating costs were $129.7 million in the first quarter of 2026, or $9.72 per Boe, higher by 4% on a per unit basis compared to the first quarter of 2025. Production taxes were $38.3 million in the first quarter of 2026, compared to $36.1 million in the first quarter of 2025. First quarter general and administrative ("G&A") costs totaled $23.2 million or $1.74 per Boe, as compared to $1.19 per Boe in the first quarter of 2025. The increase primarily reflects the $6.7 million of transaction costs associated with the Company's Ohio Utica joint acquisition which closed in February. NOG's adjusted cash G&A costs, which excludes non-cash share-based compensation and acquisition cost amounts of $3.7 million and $6.7 million, respectively, totaled $12.8 million or $0.96 per Boe in the first quarter, up $0.09 per Boe compared to the first quarter of 2025.

CAPITAL EXPENDITURES AND ACQUISITIONS

Capital expenditures for the first quarter were $270.1 million (excluding non-budgeted acquisitions and other). This was comprised of $226.5 million of total drilling and completion ("D&C") capital on organic assets, and $43.6 million of Ground Game activity, inclusive of associated development costs. Normalized well costs on the Company's AFE elections declined sequentially, averaging approximately $749 per lateral foot in the first quarter, as compared to $833 in the first quarter of 2025. NOG's Permian Basin spending was 31% of the capital expenditures for the first quarter, the Appalachian was 28%, the Williston was 24% and the Uinta was 17%.

LIQUIDITY AND CAPITAL RESOURCES

NOG had total liquidity of $1.2 billion as of March 31, 2026, consisting of $1.1 billion of committed borrowing availability under its Revolving Credit Facility and $37.0 million cash on hand.

In March 2026, the Company completed an underwritten public offering of its common stock issuing 8,288,289 shares and raising $227.9 million in net proceeds. Funds raised in the offering were applied to the outstanding borrowings on the Company's revolving credit facility.

OTHER MATTERS

NOG accounts for its assets under the Full Cost method, as opposed to the Successful Efforts method, which does not perform historical price-based asset tests. Driven by lower average oil prices, the Company recorded a non-cash ceiling test impairment charge of $268.3 million, in the first quarter of 2026, on its oil and gas assets. This non-cash charge will have no impact on cash flows of the Company.

SHAREHOLDER RETURNS

In February 2026, the Company's board of directors declared a cash dividend on the Company's common stock in the amount of $0.45 per share. The dividend is payable on April 30, 2026, to stockholders of record as of the close of business on March 30, 2026.

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, operating and financial performance, business strategy, dividend plans and practices, plans and objectives of management for future operations, industry conditions, indebtedness covenant compliance, capital expenditures, production, cash flow, borrowing base under NOG's Revolving Credit Facility, NOG's intention or ability to pay or increase dividends on its capital stock, and impairment are forward-looking statements. When used in this release, forward-looking statements are generally accompanied by terms or phrases such as "estimate," "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 current properties and properties pending acquisition; infrastructure constraints and related factors affecting NOG's properties; general economic or industry conditions, whether internationally, nationally and/or in the communities in which NOG conducts business, including any future economic downturn, cost inflation, supply chain disruptions, the impact of continued or further inflation, disruption in the financial markets, changes in the interest rate environment and actions taken by OPEC and other oil producing countries as it pertains to the global supply and demand of, and prices for, crude oil, natural gas and NGLs; ongoing legal disputes over, and potential shutdown of, the Dakota Access Pipeline; NOG's ability to identify and consummate additional development opportunities and potential or pending acquisition transactions, the projected capital efficiency savings and other operating efficiencies and synergies resulting from NOG's acquisition transactions, integration and benefits of property acquisitions, or the effects of such acquisitions on NOG's cash position and levels of indebtedness; changes in NOG's reserves estimates or the value thereof; disruption to NOG's business due to acquisitions and other significant transactions; changes in local, state, and federal laws, regulations or policies that may affect NOG's business or NOG's industry (such as the effects of tax law changes, and changes in environmental, health, and safety regulation and regulations addressing climate change, and trade policy and tariffs); conditions of the securities markets; risks associated with NOG's 3.625% convertible senior notes due 2029 (the "Convertible Notes"), including the potential impact that the Convertible Notes may have on NOG's financial position and liquidity, potential dilution, and that provisions of the Convertible Notes could delay or prevent a beneficial takeover of NOG; the potential impact of the capped call transactions undertaken in tandem with the Convertible Notes issuances, including counterparty risk; increasing attention to environmental, social and governance matters; NOG's ability to raise or access capital on acceptable terms; cyber-incidents could have a material adverse effect on NOG's business, financial condition or results of operations; changes in accounting principles, policies or guidelines; events beyond NOG's control, including a global or domestic health crisis, acts of terrorism, political or economic instability or armed conflict in oil and gas producing regions; and other economic, competitive, governmental, regulatory and technical factors affecting NOG's operations, products 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 for the year ended December 31, 2025, and Quarterly Report 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 duty to update or revise any forward-looking statements, except as may be required by the federal securities laws.

Non-GAAP Financial Measures

Adjusted Net Income, Adjusted EBITDA and Free Cash Flow are non-GAAP measures. NOG defines Adjusted Net Income as income before income taxes, excluding (i) (gain) loss on unsettled commodity derivatives, net of tax, (ii) (gain) loss on extinguishment of debt, net of tax, (iii) contingent consideration (gain) loss, net of tax, (iv) acquisition transaction costs, net of tax, (v) (gain) loss on unsettled interest rate derivatives, net of tax, and (vi) impairment of long-lived assets, net of tax. NOG defines Adjusted EBITDA as net income before (i) interest expense, (ii) income taxes, (iii) depreciation, depletion, amortization and accretion, (iv) non-cash stock-based compensation expense, (v) (gain) loss on extinguishment of debt, (vi) contingent consideration (gain) loss (vii) acquisition transaction costs, (viii) (gain) loss on unsettled interest rate derivatives, (ix) (gain) loss on unsettled commodity derivatives, (x) impairment of long-lived assets, and (xi) other non-cash adjustments. NOG defines Free Cash Flow as cash flows from operations before changes in working capital and other items, less (i) capital expenditures, excluding non-budgeted acquisitions and changes in accrued capital expenditures and other items. A reconciliation of each of these measures to the most directly comparable GAAP measure is included below.

Management believes the use of these non-GAAP financial measures provides useful information to investors to gain an overall understanding of current financial performance. Management believes Adjusted Net Income and Adjusted EBITDA provide useful information to both management and investors by excluding certain expenses and unrealized commodity gains and losses that management believes are not indicative of NOG's core operating results. Management believes that Free Cash Flow is useful to investors as a measure of a company's ability to internally fund its budgeted capital expenditures, to service or incur additional debt, and to measure success in creating stockholder value. In addition, these non-GAAP financial measures are used by management for budgeting and forecasting as well as subsequently measuring NOG's performance, and management believes it is providing investors with financial measures that most closely align to its internal measurement processes. The non-GAAP financial measures included herein may be defined differently than similar measures used by other companies and should not be considered an alternative to, or more meaningful than, the comparable GAAP measures. From time to time NOG provides forward-looking Free Cash Flow estimates or targets; however, NOG is unable to provide a quantitative reconciliation of the forward looking non-GAAP measure to its most directly comparable forward looking GAAP measure because management cannot reliably quantify certain of the necessary components of such forward looking GAAP measure. The reconciling items in future periods could be significant.

(1)	For the three months ended March 31, 2026 and March 31, 2025, this represents a tax impact using an estimated tax rate of 24.5%.
(2)	Weighted average shares outstanding - diluted, on a GAAP basis, includes diluted shares attributable to the Company's Convertible Notes due 2029. However, the offsetting impact of the capped call transactions that the Company entered into in connection therewith is not recognized on a GAAP basis. As a result, for purposes of this calculation, the Company excludes the dilutive shares to the extent they would be offset by the capped calls.
(3)	Weighted average shares outstanding - diluted, on a GAAP basis, does not include the dilutive effect of restricted stock when the Company is in a loss position. As a result, for purposes of this calculation, the Company includes the dilutive shares attributable to the restricted stock.
