Tyler Farquharson, President and CEO of Granite Ridge, commented, “Granite Ridge delivered another quarter of strong execution and disciplined growth, demonstrating the consistency of our model and the strength of our diversified portfolio. Our Operated Partnership platform continues to perform well, highlighted by Admiral Permian Resources and other key partners who are driving operational excellence and capital efficiency across our portfolio.

“Subsequent to quarter end, we further strengthened our balance sheet through proactive refinancing that enhanced our liquidity and extended our financial runway heading into 2026. These actions reflect our continued commitment to maintaining a conservative capital structure and ensuring the flexibility to pursue high-return opportunities while delivering consistent cash returns to shareholders.

“As we look ahead to 2026, Granite Ridge is well positioned to build on this momentum. Our Operated Partnerships provide a repeatable path to growth, our non-operated portfolio continues to generate steady cash flow, and our financial strength enables us to create long-term value for shareholders through commodity cycles.”

All statements other than statements of historical facts included in this release regarding, without limitation, Granite Ridge’s 2025 outlook, financial position, operating and financial performance, business strategy, plans and objectives of management for future operations, industry conditions, indebtedness covenant compliance, capital expenditures, production and cash flows are forward-looking statements.

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 November 6, 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, (gain) 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 December 31, 2024, March 31, 2025, and June 30, 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, (gain) 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:
