( NYSE : NOG ) ( “ NOG ” or “ Company ” ) today announced the Company's second quarter results . MANAGEMENT COMMENTS " The strength of the NOG model shows most clearly when the macro backdrop is at its most volatile , and the flexibility of our diversified , non - operated business model is precisely what carried us through this quarter . Adjusted EBITDA was up 17 % sequentially over the first quarter and we reiterated our full year production guidance despite less than ideal operating conditions . This directly demonstrates the resiliency of our platform . We strategically expanded our total addressable market by entering the Duvernay , a high quality , low break- even basin with significant growth potential , while also further enhancing our lower 48 footprint through our accretive and dynamic ground game program . Additionally , we opportunistically repurchased ~ 3 million shares of our stock at a highly attractive valuation , exactly the kind of disciplined capital allocation the NOG model is built to enable , ” commented Nick O'Grady , Chief Executive Officer . " NOG remains as strong and as well positioned as ever with an asset base that is materially undervalued by the public market juxtaposed against one of the strongest private asset markets in decades . We believe our value proposition will be well illuminated over time , and we remain steadfast in executing a business plan built to ensure the market recognizes both the value inherent in what we own today and our ability to generate attractive risk - adjusted returns across the cycle . " FINANCIAL RESULTS Oil and natural gas sales for the second quarter were $ 670.8 million . Second quarter GAAP net income was $ 236.6 million or $ 2.19 per diluted share . Second quarter Adjusted Net Income was $ 122.5 million or $ 1.13 per adjusted diluted share . Adjusted EBITDA in the second quarter was $ 401.0 million , a 17 % increase from the first quarter of 2026 , driven primarily by a 13 % improvement in realized commodity price per boe . See " Non - GAAP Financial Measures " below . PRODUCTION Second quarter 2026 production averaged 145,659 Boe per day , a 9 % increase from the second quarter of 2025. Oil represented approximately 47 % of total production in the second quarter at an average of 68,275 Bbls per day . As previously announced , oil volumes were impacted by approximately 7,000 Boe per day of well shut - ins and 3 deferred turn - in - lines in certain Permian assets in April , May and part of June . The wells that were shut in are back on line and the turn - in - lines are expected to TIL in the third quarter . During the quarter , NOG added 12.7 net wells to production , compared to 13.5 net wells , excluding major acquisitions , added to production in the second quarter of 2025. The Company anticipates an acceleration of TILs through the second half of 2026 . 1

Well performance continues to be strong across all of NOG’s basins. Appalachian volumes set another production record as our joint development program in West Virginia culminated mid-quarter and our Utica joint development contributed a full quarter of production. Additionally, NOG’s Uinta Assets significantly outperformed internal estimates both on legacy production as well as on the 2026 development program. PRICING During the second quarter, NOG’s unhedged net realized oil price was $90.02 per Bbl. The Company’s average differential to WTI prices was ($3.03), a 43% improvement from the second quarter of 2025. NOG’s unhedged net realized gas price in the second quarter was $2.64 per Mcf, representing a 90% realization compared with Henry Hub pricing. Natural gas realizations were pressured throughout the majority of the quarter due to weak Waha pricing, offset by solid NGL realizations and improved differentials in other regions. Conditions began to improve in late June and appear to be returning to normalized levels. HEDGING In the second quarter, the Company recorded a non-cash unrealized mark-to-market gain on derivatives of approximately $156.5 million, driven by changes to the value of the Company’s derivatives portfolio. Realized hedge losses were $86.3 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 $127.1 million in the second quarter of 2026, or $9.59 per Boe, 4% lower on a per unit basis compared to the second quarter of 2025. Production taxes were $45.7 million in the second quarter of 2026, compared to $35.6 million in the second quarter of 2025 due to higher oil prices. Second quarter general and administrative (“G&A”) costs totaled $24.5 million or $1.85 per Boe, as compared to $1.28 per Boe in the second quarter of 2025. The increase primarily reflects $7.7 million, mainly for the transaction costs associated with the Company’s Duvernay acquisition, which closed in June. NOG’s adjusted cash G&A costs, which excludes non-cash share-based compensation and acquisition cost amounts of $4.4 million and $7.7 million, respectively, totaled $12.4 million or $0.94 per Boe in the second quarter, up $0.05 per Boe compared to the second quarter of 2025. CAPITAL EXPENDITURES AND ACQUISITIONS Capital expenditures for the second quarter were $195.8 million (excluding non-budgeted acquisitions and other). This was comprised of $151.0 million of total drilling and completion (“D&C”) capital on organic assets, and $44.7 million of Ground Game activity, inclusive of associated development costs. Normalized well costs on the Company’s AFE elections increased modestly, averaging approximately $761 per lateral foot in the second quarter, as compared to $749 in the first quarter of 2026. NOG’s Permian Basin spending was 37% of the capital expenditures for the second quarter followed by the Williston at 33%, Appalachian at 14%, the Uinta at 14% and the Duvernay at 2%. LIQUIDITY AND CAPITAL RESOURCES NOG had total liquidity of $1.0 billion as of June 30, 2026, consisting of $975.0 million of committed borrowing availability under its Revolving Credit Facility and $47.6 million of cash on hand. SHAREHOLDER RETURNS In May 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 was paid on July 31, 2026, to stockholders of record as of the close of business on June 29, 2026. In August 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 October 30, 2026, to stockholders of record as of the close of business on September 29, 2026. During the second quarter, the Company repurchased 2.95 million shares of its common stock (approximately 3% of outstanding shares) at an average price of $20.37, including commissions, ~81% of which were purchased before the dividend record date. On July 10, 2026, NOG’s Board of Directors authorized a $150.0 million increase to the Company’s common stock repurchase program, which provides a current total repurchase capacity of approximately $243.0 million. 2

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.

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.

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, (vi) (gain) loss on foreign currency transactions and (vii) 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) (gain) loss on foreign currency transactions, (xi) impairment of long-lived assets, and (xii) 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. 13
