Tyler Farquharson, President and CEO of Granite Ridge, commented, “Our quarterly results continue to validate our business model, with production and cash flow again exceeding expectations. We allocate capital to the highest risk-adjusted returns across a diverse portfolio of oil and natural gas assets, driving consistent and attractive full-cycle returns. This compounding effect is accelerating our growth momentum.

“In the second quarter, we increased production by 37% year-over-year to 31,576 Boe per day, driven by a 46% rise in oil production and a 28% rise in natural gas production. Development capital expenditures of $148.6 million for the six months ended June 30 were in line with expectations, while non-budgeted acquisition capital increased due to heightened transaction activity in our Operated Partnership and Traditional Non-Op investment strategies. We are raising our full-year production guidance by 10% at the midpoint to between 31,000 and 33,000 Boe per day and increasing our capital expenditure guidance to $400-420 million to support the expanded inventory additions.”

“During the quarter, we announced that Luke Brandenburg stepped down as CEO. I am honored to lead Granite Ridge and am confident our strategy will maximize shareholder value. We deeply appreciate Luke’s significant contributions to our success and wish him the very best. Our strategy remains unchanged: underwrite development projects with full-cycle returns exceeding 25%, deliver consistent growth, and return capital to shareholders through a quarterly dividend.”

The Company’s Operated Partnership and Traditional Non-Op investment strategies continued to drive value in the second quarter of 2025. Wells in the Permian came online ahead of schedule and Utica wells exceeded forecasts. As a result, the Company has raised its full-year production guidance by 10% at the midpoint to 31,000–33,000 barrels of oil equivalent per day, achieving 28% year-over-year growth. Capital expenditure guidance has also been increased to $400–$420 million, primarily to fund acquisitions expected to close in 2025.

Granite Ridge plans to deploy approximately $120 million in acquisition capital, adding 74 net locations, with a significant portion allocated to the Permian Basin through its Operated Partnership strategy and the remaining portion to the high-performing Appalachia leasing strategy.

These acquisitions have secured three additional years of inventory at an entry cost of approximately $1.7 million per location.

Oil and natural gas sales for the second quarter of 2025 were $109.2 million. Net income was $25.1 million, or $0.19 per diluted share. Excluding non-cash and special items, Adjusted Net Income (non-GAAP) was $14.0 million, or $0.11 per diluted share.

Adjusted EBITDAX (non-GAAP) for the second quarter of 2025 totaled $75.4 million compared to $68.3 million for the second quarter of 2024. Cash flow from operating activities was $78.0 million, including $8.6 million in working capital changes. Operating Cash Flow Before Working Capital Changes (non-GAAP) was $69.5 million.

Second quarter 2025 oil production volumes totaled 16,009 barrels (“Bbls”) per day, a 46% increase from the second quarter of 2024. Natural gas production for the second quarter of 2025 totaled 93,404 thousand cubic feet of natural gas (“Mcf”) per day, a 28% increase from the second quarter of 2024. The Company’s daily production for the second quarter of 2025 grew 37% from the second quarter of the prior year to 31,576 Boe per day.

The Company’s average realized price for oil and natural gas for the second quarter of 2025, excluding the effect of commodity derivatives, was $61.41 per Bbl and $2.32 per Mcf, respectively, compared to $77.84 per Bbl and $1.98 per Mcf realized in the second quarter of 2024.

Lease operating expenses were $20.1 million ($7.00 per Boe) for the three months ended June 30, 2025 compared to $13.7 million ($6.50 per Boe) during the same period in 2024. The increase was primarily due to an overall increase in service costs, particularly saltwater disposal costs. Production and ad valorem taxes were $6.4 million for the quarter, or 6% of oil and natural gas sales. During the quarter, general and administrative expenses totaled $8.5 million, or $2.96 per Boe, inclusive of $2.8 million of nonrecurring severance and capital markets expenses and $0.4 million of non-cash stock-based compensation.

Capital expenditures for the quarter were $87.3 million comprised of $77.2 million of development capital and $10.1 million of property acquisition costs. The Company closed nine acquisitions in the Permian and Utica Basins, adding an aggregate inventory of 5.5 net undeveloped locations.

The Company had 4.9 net wells turned in-line (“TIL”) during the second quarter of 2025, compared to 9.1 net wells TIL in the second quarter of 2024.

To supplement the presentation of the Company’s financial results prepared in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”), this press release contains certain financial measures that are not prepared in accordance with GAAP, including Adjusted Net Income, Adjusted Earnings Per Share, Adjusted EBITDAX, Trailing Twelve Months Adjusted EBITDAX, Operating Cash Flow Before Working Capital Changes, and Net Debt.

See “Supplemental Non-GAAP Financial Measures” below for a description and reconciliation of each non-GAAP measure presented in this press release to the most directly comparable financial measure calculated in accordance with GAAP.

The following table sets forth summary information concerning production and operating data for the periods indicated:

The table below provides data associated with the Company’s derivatives at August 7, 2025, for the periods indicated:

The Company reports its financial results in accordance with GAAP. However, the Company believes certain non-GAAP performance measures may provide financial statement users with additional meaningful comparisons between current results, the results of its peers and the results of prior periods. In addition, the Company believes these measures are used by analysts and others in the valuation, rating and investment recommendations of companies within the oil and natural gas exploration and production industry. See the reconciliations throughout this release of GAAP financial measures to non-GAAP financial measures for the periods indicated.

Adjusted EBITDAX is presented herein and reconciled from the GAAP measure of net income because of its wide acceptance by the investment community as a financial indicator.

The Company defines Adjusted EBITDAX as net income before depletion and accretion expense, unrealized (gain) loss on derivatives – commodity derivatives, interest expense, net, non-cash stock-based compensation, income tax expense, impairment of unproved properties, impairment of long-lived assets, loss on equity investments, and other, net. Adjusted EBITDAX is not a measure of net income or cash flows as determined by GAAP.

The Company’s Adjusted EBITDAX measure provides additional information that may be used to better understand the Company’s operations. Adjusted EBITDAX is one of several metrics that the Company uses as a supplemental financial measurement in the evaluation of its business and should not be considered in isolation or as an alternative to, or more meaningful than, net income as an indicator of operating performance. Certain items excluded from Adjusted EBITDAX are significant components in understanding and assessing a company’s financial performance, such as a company’s cost of capital and tax structure, as well as the historic cost of depreciable and depletable assets. Adjusted EBITDAX, as used by the Company, may not be comparable to similarly titled measures reported by other companies. The Company believes that Adjusted EBITDAX is a widely followed measure of operating performance and is one of many metrics used by the Company’s management team and by other users of the Company’s consolidated financial statements. For example, Adjusted EBITDAX can be used to assess the Company’s operating performance and return on capital in comparison to other independent exploration and production companies without regard to financial or capital structure, and to assess the financial performance of the Company’s assets and the Company without regard to capital structure or historical cost basis.

The following table provides a reconciliation of the GAAP measure of net income to Adjusted EBITDAX for the periods indicated:

The Company defines Trailing Twelve Months Adjusted EBITDAX as the accumulation of the prior twelve months Adjusted EBITDAX. Adjusted EBITDAX for each of the quarters ended September 30, 2024, December 31, 2024, and March 31, 2025 were previously reported in an earnings release relating to the applicable quarter, and the reconciliation of net income to Adjusted EBITDAX for each quarter is included in the applicable earnings release.

The following table provides a reconciliation of the GAAP measure of net income to Trailing Twelve Months Adjusted EBITDAX for the period indicated:

The Company provides Net Debt, which is a non-GAAP financial measure. The Company defines Net Debt as long-term debt less cash as of the balance sheet date. The Company’s Net Debt to Trailing Twelve Months Adjusted EBITDAX provides investors with insight into the Company’s leverage as of the measurement date.

The following table provides a reconciliation from the GAAP measure of Debt to Net Debt and Net Debt to Trailing Twelve Months Adjusted EBITDAX ratio:

The Company provides Adjusted Net Income and Adjusted Earnings Per Share, which are non-GAAP financial measures. Adjusted Net Income and Adjusted Earnings Per Share represent earnings and diluted earnings per share determined under GAAP without regard to certain non-cash and nonrecurring items. The Company defines Adjusted Net Income as net income as determined under GAAP excluding impairments of long lived assets, unrealized (gain) loss on derivatives - commodity derivatives, loss on equity investments, deferred financing cost amortization acceleration, certain nonrecurring general and administrative expenses and tax impact on above adjustments.

The Company defines Adjusted Earnings Per Share as Adjusted Net Income divided by weighted average number of diluted shares of common stock outstanding.

The Company believes these measures provide useful information to analysts and investors for analysis of its operating results on a recurring, comparable basis from period to period. Adjusted Net Income and Adjusted Earnings Per Share should not be considered in isolation or as a substitute for earnings or diluted earnings per share as determined in accordance with GAAP and may not be comparable to other similarly titled measures of other companies.

The following table provides a reconciliation from the GAAP measure of net income to Adjusted Net Income, both in total and on a per diluted share basis, for the periods indicated:

The Company provides Operating Cash Flow (“OCF”) Before Working Capital Changes, which is a non-GAAP financial measure. The Company defines OCF Before Working Capital Changes as net cash provided by operating activities as determined under GAAP excluding changes in operating assets and liabilities such as: changes in cash due to changes in operating assets and liabilities, revenue receivable, other receivable, accounts payable and accrued liabilities, prepaid and other current assets, and other payables. The Company believes OCF Before Working Capital Changes is an accepted measure of an oil and natural gas company’s ability to generate cash used to fund development and acquisition activities and service debt or pay dividends.

This non-GAAP measure should not be considered as an alternative to, or more meaningful than, net cash provided by operating activities as an indicator of operating performance.

The following table provides a reconciliation from the GAAP measure of net cash provided by operating activities to OCF Before Working Capital Changes:
