See “Supplemental Non-GAAP Financial Measures” below for descriptions of the above non-GAAP measures as well as a reconciliation of these measures to the associated GAAP (as defined herein) measures.

Luke Brandenberg, President and CEO of Granite Ridge, commented, “We were pleased to end fourth quarter and full year 2023 with an average daily production increase of 18% and 23%, respectively. We also posted a year-over-year increase in proved reserves of 6%. This was a direct result of our successful multi-pronged strategy as we thoughtfully grow the business, and I want to thank our full team for their hard work and dedication as we continue to execute on additional opportunities to further enhance our asset base. We continued these efforts in the fourth quarter of 2023 with the closing of ten unique transactions, including two Haynesville acquisitions alongside an existing operating partner for a combined $24 million and two transactions with a Strategic Partner in the Delaware Basin including aggregate inventory of 1.9 net locations, acquisition cost of $3 million, and estimated future development cost of $18 million. While we are typically a buyer of assets, we are always looking for opportunities to redeploy capital at attractive valuations. As such, sometimes it makes sense to divest. This occurred in the fourth quarter with our sale of certain Permian Basin assets to Vital Energy for consideration that included common shares and preferred securities.”

Mr. Brandenberg concluded, “Looking forward, we continue to see a lot of runway in front of us. This view supports our 2024 guidance of an increase of approximately 7% in production at the midpoint from 2023 levels, after adjusting for the divestiture of the assets to Vital. We look forward to keeping everyone apprised of our progress as we continue to execute our proven growth strategy and support our shareholders through our ongoing quarterly cash dividend payment program.”

Oil production for the quarter totaled 12,280 barrels (“Bbls”) per day, a 8% increase from the prior year quarter.

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 March 7, 2024, 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, (gain) loss on derivatives – commodity derivatives, net cash receipts from (payments on) commodity derivatives, interest expense, (gain) loss on derivatives – common stock warrants, non-cash stock-based compensation, warrant exchange transaction, income tax expense, impairment of long-lived assets, gain on equity investments and other. 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 deletable 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 provides 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, accrued expenses, prepaid and other expenses 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.

Additionally, the Company provides Free Cash Flow, which is a non-GAAP financial measure. The Company defines Free Cash Flow as OCF Before Working Capital Changes minus development costs. The Company believes that Free Cash Flow is useful to investors as it provides measures to compare cash from operating activities and exploration and development costs across periods on a consistent basis.

These non-GAAP measures should not be considered in isolation or as alternatives to, or more meaningful than, net cash provided by operating activities as indicators of operating performance.

The following tables provide a reconciliation from the GAAP measure of net cash provided by operating activities to OCF Before Working Capital Changes and to Free Cash Flow:

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, gain on disposal of oil and natural gas properties, (gain) loss on derivatives - commodity derivatives, net cash receipts from (payments on) commodity derivatives, gain (loss) on derivatives - common stock warrants, (gain) loss on equity investments, deferred finance cost amortization acceleration, warrant exchange transaction costs, tax impact on above adjustments and changes in deferred taxes and other estimates.

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:
