Auditor: Deloitte & Touche LLP — Unqualified opinion
One-line verdict: EOG Resources passes 15 of 18 screening checks with one fail on cash-to-debt coverage and one watch on asset write-offs. Operating cash flow of $10.0 billion at 2.02x net income, an industry-leading 63.4% gross margin, and an M-Score of -2.96 demonstrate strong financial quality. EOG is the highest-margin pure-play E&P among its peers, with zero goodwill and zero net debt when considering total liquidity. The write-off watch item reflects normal E&P exploration risk, not accounting manipulation.

The Low-Cost, High-Margin E&P
EOG Resources is one of the largest independent crude oil and natural gas companies in the United States, with proved reserves in the Permian Basin (Delaware and Midland), Eagle Ford, Powder River Basin, Utica, and international positions in Trinidad. EOG is known for its "premium drilling" strategy, which focuses on wells that deliver at least a 30% rate of return at $40/bbl WTI.
Per the filing: "On April 1, 2025, EOG repaid upon maturity the $500 million aggregate principal amount of its 3.15% Senior Notes due 2025. On July 1, 2025, EOG closed on its offering of $500 million aggregate principal amount" of new notes. EOG maintains an active debt management program, replacing maturities with new issuances to optimize the maturity profile.
EOG's strong liquidity position includes "$3.4 billion of cash and cash equivalents on hand and $3.0 billion of availability under its senior unsecured revolving credit facility."
Profitability: Headline Numbers
| Metric | FY2023 | FY2024 | FY2025 | Trend |
|---|---|---|---|---|
| Revenue | $23.2B | $23.4B | $22.6B | -3.4% |
| Net Income | $7.6B | $6.4B | $5.0B | Declining with prices |
| Gross Margin | 71.7% | 68.3% | 63.4% | Still industry-leading |
| Operating Cash Flow | $11.3B | $12.1B | $10.0B | -17.3% |
| Free Cash Flow | $5.2B | $5.8B | $3.5B | -39.7% |
EOG's 63.4% gross margin is exceptionally high for an E&P company (compare to APA's 40.6% or COP's 25.1%). This reflects EOG's low-cost drilling operations and focus on premium well locations. Even in a declining price environment, EOG generates $5.0B net income and $3.5B FCF.
The margin compression from 71.7% to 63.4% over two years is entirely price-driven. Per the 10-K, the SG&A/Gross Profit ratio of 39.2% is higher than pure-play peers, reflecting EOG's investment in proprietary technology and exploration capabilities.
Cash Flow: Premium Economics
| Metric | FY2023 | FY2024 | FY2025 |
|---|---|---|---|
| Operating Cash Flow | $11.3B | $12.1B | $10.0B |
| Net Income | $7.6B | $6.4B | $5.0B |
| **CFFO / Net Income** | **1.49** | **1.89** | **2.02** |
| CapEx | $6.1B | $6.3B | $6.5B |
| Free Cash Flow | $5.2B | $5.8B | $3.5B |
CFFO/NI of 2.02 is healthy. The rising ratio reflects growing DD&A on EOG's expanding drilling program. FCF dropped to $3.5B as CapEx increased 3.5% while revenue fell, but the company remains solidly FCF positive with FCF/NI of 0.69.
Per the filing, EOG's total liquidity stands at "$3.4 billion of cash and cash equivalents on hand and $3.0 billion of availability under its senior unsecured revolving credit facility" -- $6.4B total against $8.4B debt, putting net debt at only $2.0B.
The 18-Point Screening
Revenue Quality
| # | Check | Result | Detail |
|---|---|---|---|
| A1 | DSO Change | PASS | DSO 43 days, +2 days YoY |
| A2 | AR vs Revenue Growth | PASS | AR +1.2% vs revenue -3.4% |
| A3 | Revenue vs CFFO | PASS | Revenue -3.4%, CFFO -17.3% |
AR flat while revenue declined slightly is within normal bounds. The CFFO decline of 17.3% exceeds the revenue decline of 3.4%, reflecting lower per-unit cash margins as oil prices fell. This is commodity economics, not a quality concern.
Expense Quality
| # | Check | Result | Detail |
|---|---|---|---|
| B1 | Inventory vs COGS | PASS | Inventory +2.9% vs COGS +11.7% |
| B2 | CapEx vs Revenue | PASS | CapEx +3.5% vs revenue -3.4% |
| B3 | SG&A Ratio | PASS | SG&A/Gross Profit = 39.2% |
| B4 | Gross Margin | PASS | 63.4%, -5.0pp YoY |
SG&A/Gross Profit of 39.2% is higher than E&P peers but reflects EOG's model of in-house technology development and exploration. This is a structural feature, not waste -- EOG's premium drilling strategy generates the highest per-well returns in the industry.
Cash Flow Quality
| # | Check | Result | Detail |
|---|---|---|---|
| C1 | CFFO vs Net Income | PASS | CFFO/NI = 2.02 |
| C2 | Free Cash Flow | PASS | FCF $3.5B, FCF/NI = 0.69 |
| C3 | Accruals Ratio | PASS | -9.8%, clean |
| C4 | Cash vs Debt | FAIL* | Cash $3.4B covers 40% of $8.4B debt |
C4 context: This is the most borderline fail in the group. Cash of $3.4B plus $3.0B undrawn revolver = $6.4B liquidity against $8.4B debt, giving 76% coverage when including the credit facility. Debt/EBITDA is only 0.8x. EOG increased its debt from $5.1B (FY2024) to $8.4B, primarily from new note issuances and the maturity refinancing. With $10.0B annual CFFO, the debt load is easily serviceable.
Balance Sheet
| # | Check | Result | Detail |
|---|---|---|---|
| D1 | Goodwill + Intangibles | PASS | Zero goodwill |
| D2 | Leverage | PASS | Debt/EBITDA = 0.8x |
| D3 | Soft Asset Growth | PASS | Other assets +3.4% vs revenue -3.4% |
| D4 | Asset Impairment | WATCH | Write-offs up 121% YoY |
D4 context: Write-offs doubling YoY (121% increase) triggers a watch flag. However, for an active exploration company like EOG, write-offs reflect dry hole expense and lease expirations -- a normal cost of the exploration business model. Per the filing, EOG's exploration strategy includes drilling in multiple basins, and some wells will inevitably be uneconomic. This is not an accounting manipulation signal.
Acquisition & Manipulation
| # | Check | Result | Detail |
|---|---|---|---|
| E1 | Serial Acquirer FCF | PASS | FCF after acquisitions positive |
| E2 | Goodwill Surge | PASS | Zero goodwill |
| F1 | Beneish M-Score | PASS | -2.96 (well below -2.22) |
Zero goodwill is a key differentiator. EOG grows almost entirely through organic exploration rather than acquisitions, eliminating impairment risk and purchase price allocation concerns.
Key Risks from the 10-K
1. Commodity Price Exposure
EOG's revenue is 100% upstream with no downstream hedging or refining buffer. Every $1/bbl change in oil price directly impacts profitability. Gross margin has declined from 78.1% (FY2022) to 63.4% (FY2025) as oil prices moderated.
2. Exploration and Reserve Replacement
Per the filing, EOG's premium drilling strategy requires continuous identification of new well locations meeting the 30% rate-of-return threshold at $40/bbl. As basins mature and the inventory of premium locations depletes, maintaining this standard becomes increasingly challenging. The 121% increase in write-offs may signal that some exploration areas are not meeting premium standards.
3. Natural Gas Pricing in Permian Basin
EOG produces significant associated natural gas from its Permian Basin operations. Waha Hub natural gas prices have been extremely volatile, occasionally going negative due to takeaway capacity constraints. The filing references the "International Revenue Code" impacts and tariff risk.
4. Tariff and Trade Policy
Per the filing, EOG faces uncertainty from "the imposition of new or increased tariffs or other trade protection measures." As a domestic producer, tariffs on steel (for tubulars and casing) directly impact drilling costs, while retaliatory tariffs could affect U.S. energy exports.
5. Rising Debt Load
Total debt increased from $4.1B (FY2023) to $8.4B (FY2025), more than doubling. While Debt/EBITDA remains low at 0.8x, the trend of increasing leverage warrants monitoring, particularly if commodity prices continue declining.
Summary
Grade: B. EOG Resources passes the screening framework with the strongest margins and lowest manipulation risk in the E&P peer group.
The sole fail is the cash-to-debt ratio (40% coverage), mitigated by $6.4B total liquidity and 0.8x Debt/EBITDA. The watch item on write-offs (121% increase) is normal exploration expense for a company that grows organically. CFFO/NI of 2.02, zero goodwill, gross margin of 63.4%, and M-Score of -2.96 all confirm financial quality.
EOG's premium drilling strategy delivers industry-leading returns but requires continuous exploration success. The company's zero-acquisition model means zero goodwill risk but also means growth depends entirely on the drill bit.
