Fourth Quarter and Full Year 2025 Highlights:

•Fourth quarter and full year 2025 total net income was $71.4 million and $337.3 million, respectively, and total adjusted net income(1) was $71.4 million and $335.7 million, respectively, and providing full year operating income margins of 33%. The diluted weighted average shares outstanding(2) for the fourth quarter and full year 2025 was 188.0 million and 191.1 million, respectively, representing a year-over-year decline of 4% for both periods.

•Adjusted EBITDAX(1) was $215.7 million during the fourth quarter of 2025, with drilling and completions (“D&C”) capital of $116.5 million. Adjusted EBITDAX for the full year 2025 was $906.1 million with total D&C capital of $460.7 million, representing a reinvestment rate of 51% of adjusted EBITDAX.

•Net cash provided by operating activities was $208.4 million during the fourth quarter of 2025 and $878.6 million during full year 2025. The Company generated free cash flow(1) of $74.7 million during the fourth quarter of 2025 and $426.6 million during full year 2025.

•Total production in the fourth quarter of 2025 grew 11% from fourth quarter 2024 levels to 103.8 thousand barrels of oil equivalent per day (“Mboe/d”), exceeding our earlier guidance and establishing a new quarterly record. Full year 2025 production volumes averaged 99.8 Mboe/d representing year-over-year volume growth of 11% and full year production per share growth of 16%. Fourth quarter oil production grew to 40.7 thousand barrels of oil per day (“Mbbls/d”), also a

quarterly record for Magnolia, leading to full year 2025 oil production of 39.8 Mbbls/d and year-over-year oil growth of approximately 4%.

•Total fourth quarter 2025 production at Giddings was 83.6 Mboe/d climbing by 16% compared to the prior year period, and inclusive of oil production growth of 10%. Giddings volumes were broadly supported by strong well performance throughout the field and part of which originated from newly delineated areas.

•Magnolia added 49.8 million barrels of oil equivalent (“MMboe”) of proved developed reserves in 2025, representing additions from the Company’s drilling program, and which excluded reserves related to acquisitions and price-related revisions. These organic proved developed reserve additions provide a reserve replacement ratio of 137% of our 2025 production and leading to organic proved developed Finding and Development (“F&D”) costs of $9.25 per barrel of oil equivalent for 2025.

•Magnolia purchased 2.4 million Class A Common shares during the fourth quarter for $53.4 million, representing approximately 1.3% of our outstanding shares. Total share repurchases during 2025 amounted to 8.9 million Class A Common shares, leading to a 4.4% reduction in the Company’s diluted weighted average total shares outstanding(2) compared to the prior year. Magnolia’s Board of Directors has increased the existing share repurchase authorization by an additional 10 million shares, bringing the total remaining authorization to 12.9 million Class A Common shares, which are specifically designated toward open market share repurchases.

•As previously announced, the Board of Directors declared a cash dividend of $0.165 per share of Class A common stock, and a cash distribution of $0.165 per Class B unit, payable on March 2, 2026, to shareholders of record as of February 10, 2026. This quarterly dividend payment represents a 10% increase compared to the previous rate, and providing an annualized dividend rate of $0.66 per share. This is the fifth consecutive year that Magnolia has raised its dividend rate after first initiating a dividend payment in 2021. Delivering a safe, sustainable, and growing dividend is an important element of Magnolia’s investment proposition.

•Magnolia returned 110%(3) and 75%(4) of the free cash flow generated during the fourth quarter and full year 2025, respectively, to the Company’s shareholders through a combination of share repurchases and dividends. In addition to the significant return of cash to shareholders, Magnolia completed several small bolt-on oil and gas property acquisitions during 2025 totaling $66.6 million. We started 2025 with $260.0 million of cash on our balance sheet and ended the year with $266.8 million of cash and an undrawn $450 million revolving credit facility.

“Magnolia delivered another year of exceptional and consistent performance in 2025, marked by the steady execution of our capital-efficient business model and our high quality assets,” said Chairman, President, and CEO Chris Stavros. “I am especially proud of the unwavering dedication and focus shown by both our operating teams in the field and our Houston staff. Their continued hard work and perseverance is a significant factor behind Magnolia’s success.

“We continually remind the financial community that Magnolia’s primary goals and objectives are to be the most efficient operator of our best-in-class oil and gas assets, to generate the highest returns on those assets, and while employing the least amount of capital for drilling and completing wells, no matter the product prices. Last year was another example of our successful delivery on these goals. We returned 75 percent of the free cash flow generated during 2025 to our shareholders through our secure and growing cash dividend and our ongoing share repurchase program. And, we continued to enhance and expand our asset base through opportunistic bolt-on acquisitions stemming from our accumulated subsurface knowledge and experience, near areas where we operate and understand well.

“We achieved double-digit production growth with less capital than originally planned, completed approximately $67 million of bolt-on acquisitions furthering our resource opportunity set, repurchased 4 percent of our outstanding shares, and recently announced a 10 percent increase in our dividend — our fifth consecutive annual increase. Magnolia ended 2025 on a strong note, with record quarterly oil and gas volumes, resulting in 11 percent year-over-year production growth. Notably, this was all accomplished organically, as our cash on the balance sheet increased during the year, while generating a sector leading return on capital employed of 18 percent during 2025.

“As we enter 2026, Magnolia is well-positioned and consistently guided by the principles of our business model. Our high-quality assets and strategy of continued capital spending discipline, proactive cost management and pursuit of further operational efficiencies should serve us well during periods of product price volatility. Our consistent policy of low leverage and lack of commodity hedges is central to our strategy, providing us with downside protection while allowing for upside to product prices and the ability to generate value through commodity cycles.”

Operational Update

Fourth quarter and full-year 2025 total company production averaged 103.8 and 99.8 Mboe/d, representing a 11 percent year over year increase for both periods. Giddings production represented 79 percent of total company volumes during 2025. Fourth quarter and full-year 2025 production from Giddings both increased by 16 percent, compared to the prior year periods with Giddings oil production growing by 10 percent compared to fourth quarter 2024. Last year’s production volume growth benefited from continued strong well performance throughout Magnolia’s assets with exceptional well results in Giddings, part of which originated from a new development area.

Magnolia’s fourth quarter and full year 2025 capital spending on drilling, completions and associated facilities was $116.5 million and $460.7 million, respectively. Magnolia delivered a more capital efficient program during 2025, with our drilling and completions team continuing to generate productivity gains in 2025 which included an 8 percent year-over-year improvement in drilling feet per day and a 6 percent increase in completed feet per day in Giddings. The Company also spent less capital during 2025 because of stronger than expected well performance allowing us to defer several completions into 2026. Additionally, lease operating expenses declined by 7 percent to $5.12 per boe during the full year 2025 compared to 2024 levels as the Company continues to drive down operating costs in the field and across our assets.

Magnolia plans to operate two drilling rigs and one completion crew during 2026 and expects to maintain this level of activity throughout year. While this year’s activity is expected to have similar characteristics to the 2025 operating plan, lower anticipated overall well costs combined with improved operating efficiencies is expected to allow for more wells to be drilled, completed and turned in line lending support to Magnolia’s overall high-margin growth. The Company’s current development program utilizing two operated rigs and one completion crew has been consistently in place for the last five years, driving total Company production growth by greater than 50 percent and more than doubling our production volumes in Giddings.

Approximately 75 to 80 percent of our 2026 activity is expected to consist of multi-well development pads in the Giddings area with the remainder focused on the Karnes area. The development program at Giddings consists of drilling multi-well pads throughout our core 240,000 net acre development area. This creates a balanced and efficient program providing more consistent year-over-year results. Magnolia plans to continue to allocate a modest amount of capital toward appraisal activities throughout our large acreage footprint in south Texas designed to further enhance our resource opportunity set and to further de-risk our sizable acreage position particularly in Giddings.

2025 Oil and Gas Reserves

Magnolia’s total 2025 proved reserves increased 10 percent to 210.2 MMboe from 191.7 MMboe at year end 2024 replacing 151 percent(5) of our 2025 production. Magnolia books only one year of proved undeveloped reserves and as a result 79 percent of its 2025 proved reserves were developed. The proved undeveloped reserves represent what we plan to convert to the proved developed category during 2026 as part of our capital and activity program.

Magnolia’s total proved developed reserves at year end 2025 were 166.6 MMboe. Excluding acquisitions, sales, and price-related revisions, the Company added 49.8 MMboe of proved developed reserves during the year. Total costs incurred excluding property acquisition costs, exploration expenses and asset retirement obligations were $460.7 million in 2025 resulting in organic proved developed F&D costs of $9.25 per boe. During the three-year period from 2023 to 2025, Magnolia’s organic proved developed F&D costs averaged $9.85 per boe.

Additional Guidance

Magnolia currently estimates its total 2026 D&C capital spending to be in the range of $440 to $480 million and that is comparable to last year, which includes an estimate of non-operated capital that is similar to 2025. The Company currently expects this year’s capital spending program and activity to deliver full-year total production growth of approximately 5 percent for 2026. First quarter 2026 D&C capital spending is estimated at approximately $125 million and is expected to be the highest quarterly rate of spending for the year. Total production for the first quarter is estimated to be approximately 102 Mboe/d which includes approximately 1.5 Mboe/d of downtime impact resulting from the recent winter storm, all of which has been fully restored.

Oil price differentials are anticipated to be approximately a $3 per barrel discount to Magellan East Houston and Magnolia remains completely unhedged for all its oil and natural gas production. The fully diluted share count for the first quarter of 2026 is expected to be approximately 187 million shares, which is 4 percent reduction from first quarter 2025 levels.

Annual Report on Form 10-K

Magnolia's financial statements and related footnotes will be available in its Annual Report on Form 10-K for the year ended December 31, 2025, which is expected to be filed with the U.S. Securities and Exchange Commission (“SEC”) on February 12, 2026.

Non-GAAP Financial Measures

Reconciliation of net income to adjusted EBITDAX

In this press release, we refer to adjusted EBITDAX, a supplemental non-GAAP financial measure that is used by management and external users of our consolidated financial statements, such as industry analysts, investors, lenders, and rating agencies. We define adjusted EBITDAX as net income before interest expense, income taxes, depreciation, depletion and amortization, amortization of intangible assets, exploration expenses, and accretion of asset retirement obligations, adjusted to exclude the effect of certain items included in net income. Adjusted EBITDAX is not a measure of net income in accordance with GAAP.

Our management believes that adjusted EBITDAX is useful because it allows them to more effectively evaluate our operating performance and compare the results of our operations from period to period and against our peers without regard to our financing methods or capital structure. We also believe that securities analysts, investors, and other interested parties may use adjusted EBITDAX in the evaluation of our Company. We exclude the items listed above from net income in arriving at adjusted EBITDAX because these amounts can vary substantially from company to company within our industry depending upon accounting methods and book values of assets, capital structures and the method by which the assets were acquired. Adjusted EBITDAX should not be considered as an alternative to, or more meaningful than, net income as determined in accordance with GAAP or as an indicator of our operating performance or liquidity. 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 costs of depreciable assets, none of which are components of adjusted EBITDAX. Our presentation of adjusted EBITDAX should not be construed as an inference that our results will be unaffected by unusual or non-recurring items. Our computations of adjusted EBITDAX may not be comparable to other similarly titled measures of other companies.

The following table presents a reconciliation of net income to adjusted EBITDAX, our most directly comparable financial measure, calculated and presented in accordance with GAAP:

Non-GAAP Financial Measures

Reconciliation of net income to adjusted net income

Our presentation of adjusted net income is a non-GAAP measure because it excludes the effect of certain items included in net income. Management uses adjusted net income to evaluate our operating and financial performance because it eliminates the impact of certain items that management does not consider to be representative of the Company’s on-going business operations. As a performance measure, adjusted net income may be useful to investors in facilitating comparisons to others in the Company’s industry because certain items can vary substantially in the oil and gas industry from company to company depending upon accounting methods, book value of assets, and capital structure, among other factors. Management believes adjusting these items facilitates investors and analysts in evaluating and comparing the underlying operating and financial performance of our business from period to period by eliminating differences caused by the existence and timing of certain expense and income items that would not otherwise be apparent on a GAAP basis. However, our presentation of adjusted net income may not be comparable to similar measures of other companies in our industry.

Non-GAAP Financial Measures

Reconciliation of revenue to adjusted cash operating margin and to operating income margin

Our presentation of adjusted cash operating margin and total adjusted cash operating costs are supplemental non-GAAP financial measures that are used by management. Total adjusted cash operating costs exclude the impact of non-cash activity. We define adjusted cash operating margin per boe as total revenues per boe less operating expenses per boe. Management believes that total adjusted cash operating costs per boe and adjusted cash operating margin per boe provide relevant and useful information, which is used by our management in assessing the Company’s profitability and comparability of results to our peers.

As a performance measure, total adjusted cash operating costs and adjusted cash operating margin may be useful to investors in facilitating comparisons to others in the Company’s industry because certain items can vary substantially in the oil and gas industry from company to company depending upon accounting methods, book value of assets, and capital structure, among other factors. Management believes excluding these items facilitates investors and analysts in evaluating and comparing the underlying operating and financial performance of our business from period to period by eliminating differences caused by the existence and timing of certain expense and income items that would not otherwise be apparent on a GAAP basis. However, our presentation of adjusted cash operating margin may not be comparable to similar measures of other companies in our industry.

Non-GAAP Financial Measures

Reconciliation of net cash provided by operating activities to free cash flow

Free cash flow is a non-GAAP financial measure. Free cash flow is defined as cash flows from operations before net change in operating assets and liabilities less additions to oil and natural gas properties and changes in working capital associated with additions to oil and natural gas properties. Management believes free cash flow is useful for investors and widely accepted by those following the oil and gas industry as financial indicators of a company’s ability to generate cash to internally fund drilling and completion activities, fund acquisitions, and service debt. It is also used by research analysts to value and compare oil and gas exploration and production companies and is frequently included in published research when providing investment recommendations. Free cash flow is used by management as an additional measure of liquidity. Free cash flow is not a measure of financial performance under GAAP and should not be considered an alternative to cash flows from operating, investing, or financing activities.

Disclaimer FORWARD LOOKING STATEMENTS The information in this presentation includes forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. All statements, other than statements of present or historical fact included in this presentation, regarding Magnolia’s strategy, future operations, financial position, estimated revenues and losses, projected costs, prospects, plans and objectives of management are forward looking statements. When used in this presentation, the words could, should, will, may, believe, anticipate, intend, estimate, expect, project, the negative of such terms and other similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain such identifying words. These forward-looking statements are based on management’s current expectations and assumptions about future events. Except as otherwise required by applicable law, Magnolia disclaims any duty to update any forward-looking statements, all of which are expressly qualified by the statements in this section, to reflect events or circumstances after the date of this presentation. Magnolia cautions you that these forward-looking statements are subject to all of the risks and uncertainties, most of which are difficult to predict and many of which are beyond the control of Magnolia, incident to the development, production, gathering and sale of oil, natural gas and natural gas liquids. In addition, Magnolia cautions you that the forward looking statements contained in this presentation are subject to the following factors: (i) the market prices of oil, natural gas, NGLs, and other products or services; (ii) the supply and demand for oil, natural gas, NGLs, and other products or services, including impacts of actions taken by OPEC and other state-controlled oil companies; (iii) the outcome of any legal proceedings that may be instituted against Magnolia; (iv) Magnolia’s ability to realize the anticipated benefits of its acquisitions, which may be affected by, among other things, competition and the ability of Magnolia to grow and manage growth profitably; (v) legislative, regulatory, or policy changes, including those following the change in presidential administrations; (vi) geopolitical and business conditions in key regions of the world; (vii) cybersecurity threats, including increased use of artificial intelligence technologies; and (viii) the possibility that Magnolia may be adversely affected by other economic, business, and/or competitive factors, including inflation. Should one or more of the risks or uncertainties described in this presentation occur, or should underlying assumptions prove incorrect, actual results and plans could differ materially from those expressed in any forward-looking statements. Additional information concerning these and other factors that may impact the operations and projections discussed herein can be found in Magnolia’s filings with the SEC, including its Annual Report on Form 10-K for the fiscal year ended December 31, 2025, which is expected to be filed with the SEC on February 12, 2026. Magnolia’s SEC filings are available publicly on the SEC’s website at www.sec.gov. NON-GAAP FINANCIAL MEASURES This presentation includes non-GAAP financial measures, including adjusted net income, free cash flow, adjusted EBITDAX, adjusted cash operating costs, adjusted cash operating margin and return on capital employed. Magnolia believes these metrics are useful because they allow Magnolia to more effectively evaluate its operating performance and compare the results of its operations from period to period and against its peers without regard to accounting methods or capital structure. Magnolia does not consider these non-GAAP measures in isolation or as an alternative to similar financial measures determined in accordance with GAAP. The computations of these non-GAAP measures may not be comparable to other similarly titled measures of other companies. Adjusted net income and adjusted EBITDAX should not be considered an alternative to, or more meaningful than, net income as determined in accordance with GAAP. Certain items excluded from free cash flow, adjusted net income, adjusted EBITDAX, adjusted cash operating costs, adjusted cash operating margin, adjusted operating margin and return on capital employed are significant components in understanding and assessing a company’s financial performance and should not be construed as an inference that its results will be unaffected by unusual or non-recurring terms. As performance measures, adjusted net income, adjusted EBITDAX, adjusted cash operating costs, adjusted cash operating margin and return on capital employed may be useful to investors in facilitating comparisons to others in the Company’s industry because certain items can vary substantially in the oil and gas industry from company to company depending upon accounting methods, book value of assets, and capital structure, among other factors. Management believes excluding these items facilitates investors and analysts in evaluating and comparing the underlying operating and financial performance of our business from period to period by eliminating differences caused by the existence and timing of certain expense and income items that would not otherwise be apparent on a GAAP basis. As a liquidity measure, management believes free cash flow is useful for investors and widely accepted by those following the oil and gas industry as financial indicators of a company’s ability to generate cash to internally fund drilling and completion activities, fund acquisitions, and service debt. Our presentation of adjusted net income, adjusted EBITDAX, free cash flow, adjusted cash operating costs, adjusted cash operating margin and return on capital employed may not be comparable to similar measures of other companies in our industry. A free cash flow reconciliation is shown on page 21, adjusted EBITDAX reconciliation is shown on page 22, adjusted net income is shown on page 23, adjusted cash operating costs and adjusted cash operating margin reconciliations are shown on page 15 and ROCE is shown on page 25 of the presentation.
