EOG vs MGY: Which Is the Better Buy in 2026?
Last updated September 2026
Short answer
EOG is the larger of the two ($77.81B market cap): the incumbent the market prices for continued execution (10.30x forward earnings, beta 0.28). MGY is the smaller challenger ($6.71B), cheaper on forward earnings (8.51x): more room to run, but more to prove. The real question is which set of drivers you believe, and whether owning one (or both) leaves you over-concentrated.
EOG vs MGY: the tie-breaker metrics
Same yardstick, side by side (as of September 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.
| Metric | EOG | MGY | What it tells you |
|---|---|---|---|
| Market cap | $77.81B | $6.71B | Size. The larger name is the incumbent; the smaller has more room to grow and more to prove. |
| Forward P/E | 10.30 | 8.51 | Valuation on next year's expected earnings, the same yardstick for both. Lower is cheaper for that growth; higher means the market is paying up. |
| Trailing P/E | 11.54 | 12.08 | Valuation on the last 12 months. A big drop from trailing to forward means the market expects earnings to jump, so more growth is already in the price. |
| Beta | 0.28 | 0.70 | Volatility vs the market. Above 1 swings harder than the index; below 1 is steadier. Higher beta means bigger drawdowns to hold through. |
| Price vs 52-week range | 90% of range | 56% of range | Where today's price sits between the 52-week low and high. Near the high is momentum with less margin of safety; near the low is out of favor or a discount, depending on why. |
| Price / book | 2.45 | 2.34 | How much you pay over book value. Very high can signal an asset-light, high-return business or a rich price. |
Reading it: MGY is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.
Before you buy: how EOG and MGY affect your concentration
The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. EOG and MGY share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.
This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined EOG and MGY exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

What does EOG Resources (EOG) do?
EOG Resources is one of the largest independent crude oil and natural gas exploration and production companies in the United States, with proved reserves primarily in the Permian Basin (Delaware sub-basin), the Eagle Ford in South Texas, and, following the August 2025 acquisition of Encino Acquisition Partners, a major position in Ohio's Utica Shale. The company makes money almost entirely by finding, drilling, and selling hydrocarbons: crude oil and condensate dominate revenue (roughly $12.5 billion of the ~$22.3 billion in U.S. revenue reported for fiscal 2025), with natural gas liquids and natural gas providing the remainder. EOG's operating philosophy centers on drilling only what it calls 'premium' wells, defined as those expected to return at least 30% after-tax at conservative commodity prices, which underpins its reputation as one of the most cost-efficient operators in the sector. EOG traces its origins to Enron Oil and Gas, which was spun off and renamed EOG Resources in 1999 and is headquartered in Houston, Texas. Ezra Y. Yacob, who joined the company in 2005 as a geoscientist, became CEO in October 2021 and Chairman in October 2022; under his leadership the company has expanded its multi-basin portfolio, executed the transformative Encino acquisition, and maintained a consistent capital-return framework while targeting international growth opportunities in the UAE and Bahrain.
What does Magnolia Oil & Gas (MGY) do?
Magnolia Oil & Gas is an independent exploration and production company concentrated in the core of South Texas, where it operates in the Eagle Ford Shale and Austin Chalk across two main areas, Karnes and Giddings. As of March 2026 it held interests in roughly 2,890 gross wells and produced about 102.6 thousand barrels of oil equivalent per day, with oil making up around 40% of volumes. The company's strategy centers on delivering steady, moderate production growth (guidance of about 5% for 2026) while keeping capital spending disciplined and reinvestment rates low, which lets it generate free cash flow across commodity cycles.
EOG vs MGY: how do they differ?
Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.
- EOG drivers: Premium-well discipline drives durable free cash flow; Utica Shale adds a third foundational growth platform.
- MGY drivers: Low-leverage balance sheet; Free cash flow and shareholder returns.
Which fits which kind of investor
A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: EOG's revenue and free cash flow are tightly linked to crude oil and natural gas prices, so a sustained commodity downturn is the central bear-case scenario: lower realized prices shrink margins quickly and could pressure the company's commitment to returning at least 70% of annual free cash flow. For MGY, magnolia's results are highly sensitive to oil and natural gas prices because the company generally does not hedge, so a sustained downturn in commodity prices would pressure revenue, cash flow, and buybacks.
EOG or MGY: which should you pick?
Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick EOG if you believe its drivers more; MGY if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the EOG and MGY guides.
EOG vs MGY: the full fundamentals
EOG. EOG trades at a low-teens price-to-earnings multiple, which is roughly 30% below the broader Energy sector average of approximately 15x, reflecting the market's tendency to discount commodity-linked earnings. The ~6x EV/EBITDA multiple is consistent with peer large-cap independents and suggests the market is pricing in neither a premium for EOG's capital discipline nor a deep discount for commodity risk. The company's payout ratio is approximately 43%, leaving capacity to sustain and grow the dividend even if earnings soften modestly.
MGY. Magnolia trades around a mid-teens trailing earnings multiple with a lower forward multiple reflecting analyst expectations, a premium many attribute to its low leverage and consistent free cash flow. First quarter 2026 revenue of about $358 million and net income near $100 million came alongside production growth of roughly 6% year over year. Valuation and profitability move with commodity prices, so multiples can shift quickly with the oil and gas cycle.
Headline figures (approximate, 2026-06-27): EOG shows revenue (fy 2025) ~$22.9 billion, net income (fy 2025, gaap) ~$5.0 billion, adjusted net income (fy 2025) ~$5.5 billion, free cash flow (fy 2025) ~$4.7 billion; MGY shows market cap ~$4.8B, revenue (ttm) ~$1.4B, q1 2026 revenue ~$358M, q1 2026 net income ~$100M.
The bottom line: EOG vs MGY
EOG and MGY are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme. Walnut can show your combined EOG and MGY exposure against your real portfolio. It is not an investment adviser.

FAQ
What is the difference between EOG and MGY?
+
EOG Resources is one of the largest independent crude oil and natural gas exploration and production companies in the United States, with proved reserves primarily in the Permian Basin (Delaware sub-basin), the Eagle Ford in South Texas, and, following the August 2025 acquisition of Encino Acquisition Partners, a major position in Ohio's Utica Shale. Magnolia Oil & Gas is an independent exploration and production company concentrated in the core of South Texas, where it operates in the Eagle Ford Shale and Austin Chalk across two main areas, Karnes and Giddings. They show up together because they share investment themes, but they are different businesses, so the better fit depends on which thesis you are expressing.
Is EOG or MGY the better stock?
+
Neither is universally better. EOG is the larger incumbent; MGY is the smaller challenger and looks cheaper on forward earnings. Walnut is informational, not investment advice. Compare what each does, the tie-breaker metrics above, and the risks, then decide which fits your thesis and what you already own.
Which is cheaper, EOG or MGY?
+
On forward P/E (as of September 2026), EOG trades at 10.30x and MGY at 8.51x, so MGY is the cheaper of the two on next year's expected earnings. A lower multiple is not automatically the better buy: a richer valuation can be justified by faster growth, and a lower one can reflect real risk. Weigh the multiple against how fast each business is compounding.
Should you own both EOG and MGY?
+
Because they share themes, owning both concentrates you in that theme. That can be intentional (a focused bet) or accidental (less diversification than it looks). Walnut can show your combined exposure across both, and whether adding either over-concentrates you, before you buy.
What are the risks of EOG vs MGY?
+
EOG: EOG's revenue and free cash flow are tightly linked to crude oil and natural gas prices, so a sustained commodity downturn is the central bear-case scenario: lower realized prices shrink margins quickly and could pressure the company's commitment to returning at least 70% of annual free cash flow. The Encino acquisition added meaningful debt (funded with approximately $3.5 billion of new borrowings), introducing integration risk and a modestly higher leverage profile at a time when natural gas prices remain volatile. Regulatory risk is real: tighter permitting on federal lands, pipeline restrictions, or changes to LNG export policy could constrain both production growth and EOG's gas monetization strategy. Finally, the energy transition creates long-term demand uncertainty for fossil fuels, even if near-term fundamentals remain supportive. MGY: Magnolia's results are highly sensitive to oil and natural gas prices because the company generally does not hedge, so a sustained downturn in commodity prices would pressure revenue, cash flow, and buybacks. Its assets are geographically concentrated in South Texas, which raises exposure to regional operating, weather, and regulatory factors. Growth depends partly on acquisitions, which carry integration, valuation, and financing risk, and drilling inventory eventually needs replenishment. Broader energy-sector regulation, cost inflation for services, and the long-term energy transition add uncertainty. As with any single stock, outcomes can differ materially from expectations.
