•Magnolia reported first quarter 2021 net income attributable to Class A Common Stock of $63.2 million, or $0.37 per diluted share. First quarter 2021 total net income was $91.5 million and adjusted net income was $93.8 million, or $0.38 per diluted share.

•Adjusted EBITDAX for the first quarter of 2021 was $150.8 million, a 54% sequential quarterly increase driven by both higher overall production and stronger product prices. Total capital allocated to drilling and completions (“D&C”) during the first quarter was $38.9 million, or 26% of adjusted EBITDAX.

•Net cash provided by operating activities was $118.2 million and the Company generated free cash flow(1) of $100.0 million during the first quarter.

•During the first quarter of 2021, we generated operating income as a percent of revenue of 48%, compared to 29% during fourth quarter 2020.

•Total production in the first quarter of 2021 increased 3% sequentially to 62.3 thousand barrels of oil equivalent per day (“Mboe/d”). Production at Giddings achieved another record level in the first quarter with total volumes of 34.6 Mboe/d increasing 22% sequentially and 45% from prior year levels. Giddings oil production of 11.3 Mbbl/d increased by 32% sequentially and 73% over the same period last year.

•Magnolia spent $88 million reducing its shares during the first quarter of 2021. As a result, the fully diluted share count is expected to decline by approximately 4% to 245 million diluted shares in the second quarter of 2021 from 255 million shares in the fourth quarter of 2020. Magnolia ended the first quarter with 12.6 million Class A Common shares remaining under the current share repurchase authorization.

•Magnolia had approximately $178.2 million of cash on its balance sheet at the end of the first quarter of 2021 and remains undrawn on its $450.0 million revolving credit facility. The Company has no debt maturities until 2026 and has no plans to increase its debt levels.

•As stated earlier this year, Magnolia expects to begin paying a semi-annual cash dividend during the third quarter of 2021.

(1)Adjusted net income, adjusted earnings per share, adjusted EBITDAX, and free cash flow are non-GAAP financial measures. For reconciliations to the most comparable GAAP measures, please see “Non-GAAP Financial Measures” at the end of this press release.

(2) Weighted average total shares outstanding include diluted weighted average shares of Class A Common Stock outstanding during the period and shares of Class B Common Stock, which are anti-dilutive in the calculation of weighted average number of common shares outstanding.

“Magnolia had a very strong start to 2021, achieving record quarterly earnings. The characteristics of our strategy and business model should gain momentum through the year as our per share and unit metrics continue to improve,” said Chairman, President and CEO Steve Chazen. “Our disciplined approach toward allocating capital to our assets is expected to generate moderate growth and strong profit margins this year, while generating meaningful free cash flow.

“Despite lower capital spending, total production continued to grow in the first quarter, demonstrating the quality of our assets. The growth in volumes was driven by record production from the Giddings area, which increased 22 percent sequentially and 45 percent compared to the prior-year quarter. Based on continued strong well results in Giddings and increased activity in Karnes, we now expect our full-year 2021 production to grow 6 to 9 percent compared to prior year levels, while spending somewhat less than $300 million.

“Our ongoing free cash flow generation and strong financial position will allow us to allocate the excess cash toward accretive, small bolt-on property acquisitions, or repurchasing our shares. We used our free cash flow and some of our balance sheet cash to reduce our share count by roughly 4 percent compared to fourth quarter 2020 levels. We continue to target repurchasing around 1 percent of our outstanding shares each quarter. In addition, Magnolia plans to pay its first semi-annual dividend during the third quarter of this year. Magnolia’s oil production remains unhedged as part of our strategy, allowing us to fully capture the benefit of improved prices.”

Operational Update

First quarter total company production averaged 62.3 Mboe/d, representing a 3 percent increase from fourth quarter 2020 levels. The higher production outcome was a result of better-than-expected production at our Giddings asset and as several new wells were turned in-line. Giddings and Other production averaged 34.6 Mboe/d representing a 22 percent increase in sequential volumes and a 45 percent increase from the same prior-year quarter. Oil production at Giddings averaged 11.3 Mbbl/d, a 32 percent sequential increase and a 73 percent increase compared to last year’s first quarter. Production in the Karnes area averaged 27.7 Mboe/d during the first quarter of 2021.

We plan to add a second drilling rig this summer. One rig will continue drilling multi-well pads in our Giddings area. The second rig will operate in both the Karnes and Giddings areas, including some appraisal wells at Giddings. Total well costs associated with drilling, completion and facilities continue to average about $6 million per well at Giddings and we expect to drill about 2 wells per month.

Guidance

Inclusive of the additional rig for the back half of the year, we expect Magnolia’s capital spending for drilling and completing wells to be somewhat less than $300 million this year. Our D&C capital is expected to increase during the second quarter and during the second half of the year, which coincides with the added activity. Magnolia’s total production for 2021 is currently expected to grow 6 to 9 percent compared to full-year 2020 levels.

Looking at the second quarter of 2021, total production is forecast to be about 66 Mboe/d, a 6 percent increase from first quarter production levels. Oil price differentials are anticipated to be approximately a $3 per barrel discount to Magellan East Houston (“MEH”) during the second quarter. The fully diluted share count for the second quarter of 2021 is expected to be approximately 245 million shares which is 4 percent lower than fourth quarter 2020 levels.

Quarterly Report on Form 10-Q

Magnolia's financial statements and related footnotes will be available in its Quarterly Report on Form 10-Q for the three months ended March 31, 2021, which is expected to be filed with the U.S. Securities and Exchange Commission (“SEC”) on May 5, 2021.

Non-GAAP Financial Measures

Reconciliation of net income (loss) 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 (loss) before interest expense, income taxes, depreciation, depletion and amortization, amortization of intangible assets, exploration costs, and accretion of asset retirement obligations, adjusted to exclude the effect of certain items included in net income (loss). 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 (loss) 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 (loss) 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 (loss) to adjusted EBITDAX, our most directly comparable financial measure, calculated and presented in accordance with GAAP:

Non-GAAP Financial Measures

Reconciliation of net income (loss) attributable to Class A Common Stock to adjusted earnings

Our presentation of adjusted earnings and adjusted earnings per share are non-GAAP measures because they exclude the effect of certain items included in net income (loss) attributable to Class A Common Stock. Management uses adjusted earnings and adjusted earnings per share 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 earnings 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 earnings and adjusted earnings per share 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 are frequently included in published research when providing investment recommendations. Free cash flow, therefore, is an additional measure of liquidity, but 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.
