1) Business snapshot

  • Core businesses: Upstream (oil & gas), Product Solutions (refining/fuels + chemicals + specialties), and Low Carbon Solutions (CCS, hydrogen, lower-emission fuels).
  • Advantaged resource focus: Permian, Guyana, LNG growth (plus Brazil, Qatar, Mozambique, PNG, U.S.).
  • Moat (in plain English): scale + integration + deep project bench + balance sheet resilience; ability to fund multi-year projects through cycles.
  • What can go right: execution of Permian & Guyana growth, continued structural cost savings, disciplined capital allocation (dividend + buybacks).
  • What can go wrong: commodity price downside, downstream/chemical margin compression, cost inflation, political/regulatory shifts, and project execution risk.
Cyclical note: XOM's cash generation is heavily driven by oil & gas prices and industry margins; valuation must be framed around a mid-cycle commodity deck, not a single year's spot conditions.

Notes on normalization & one-offs
  • Management reports both GAAP and non-GAAP cash flow measures (e.g., "Free Cash Flow" and "Free Cash Flow excluding working capital").
  • For valuation, this memo treats mid-cycle cash generation (e.g., at a $65 real Brent planning basis) as the anchor, to avoid over-weighting any single oil-price environment.
  • 2025 includes growth acquisitions and continued share repurchases; the share count used is the latest reported shares outstanding (issued less treasury) at Sep 30, 2025.

3) Key drivers & assumptions

  • Commodity deck (explicit): Base case aligned to management's planning basis of $65 real Brent with downstream/chemical margins at 10-year averages.
  • Advantaged growth: Upstream growth led by Permian and Guyana; mix shift toward advantaged barrels.
  • Capital discipline: Capex held roughly flat in real terms; focus on high-return projects.
  • Cost structure: Continued structural cost savings, but not assuming full plan execution in the base case.
  • Share count: Current shares outstanding used; per-share upside from future buybacks is a potential tailwind but not explicitly modeled.
  • Terminal growth: 2.0% reflecting a mature, cyclical enterprise.
Base-case cash flow forecast inputs (what this DCF assumes)
  • 2025E starting FCFF: $27.0B (conservative run-rate from 2025 year-to-date free cash flow plus a normalized fourth quarter).
  • FCFF growth (2026–2030): 6.0% per year, reflecting advantaged volume growth + efficiency gains.
  • Terminal growth: 2.0%.
  • Net debt and other claims: net debt ≈ $28.2B and noncontrolling interests ≈ $7.7B deducted from enterprise value.

4) Discount rate (WACC) with math

Component Assumption Notes
Risk-free rate (10Y U.S.)4.14%Used as the long-term risk-free anchor.
Equity risk premium (ERP)5.5%Conservative long-run ERP assumption.
Beta1.05Conservative cyclicality + commodity sensitivity.
Cost of equity9.92%Re = Rf + β×ERP
Pre-tax cost of debt4.50%Conservative marginal borrowing cost.
Tax rate28.3%Approx. FY2024 effective rate.
After-tax cost of debt3.23%Rd × (1 − T)
Target capital structure87% equity / 13% debtAnchored to reported debt-to-capital.
WACC9.00%WACC = We×Re + Wd×Rd×(1−T)
Why WACC is the "fulcrum" for oil majors
  • With a large terminal value component, small changes in WACC can swing intrinsic value materially.
  • For cyclicals, a "too low" WACC can silently assume away cycle risk. This memo uses a conservative ~9% base WACC and shows a sensitivity grid.

5) DCF valuation results (base case)

Equity value (to XOM holders)430.56
Intrinsic value per share$102.10
How to read this DCF for a cyclical
  • The DCF is anchored to a mid-cycle cash generation level and assumes moderate growth from advantaged assets and efficiency.
  • Bear/bull outcomes are primarily driven by commodity prices and industry margins, not financial leverage.

6) Sensitivity table (per-share intrinsic value)

Terminal g WACC 8% WACC 9% WACC 10%
1%$106$91$80
2%$121$102$88
3%$142$117$98
4%$173$137$112

Heatmap shading is relative within the table (higher intrinsic value = "greener").

7) "Grandma-safe" conclusion

Decision framing (no stock price used)
  • Base intrinsic value: $102/sh
  • Fair value range: $52 – $155/sh
  • Grandma-safe buy zone (≈35% MOS): ≤ $66/sh

Top 5 things that could make this wrong

  1. Commodity prices (especially oil) settle below the mid-cycle deck for a prolonged period.
  2. Downstream/chemical margins stay structurally weak (overcapacity, demand softness, regulations).
  3. Execution slippage or cost inflation on major projects (Permian, Guyana, LNG, chemicals).
  4. Capital allocation changes (more M&A / higher capex / lower buybacks) reduce per-share compounding.
  5. Policy/tax/regulatory shocks (windfall taxes, carbon costs, geopolitical restrictions).

What would justify paying closer to fair value?

  • Clear evidence of sustained growth in advantaged volumes and unit profitability.
  • Structural cost savings continue without impairing reliability and safety.
  • Capex remains disciplined while cash returns remain robust through a full cycle.

Not investment advice. This is a valuation model with assumptions; real-world outcomes can differ materially.

Appendix

Case definitions (bear/base/bull)
  • Bear: lower commodity deck (e.g., $55 real Brent) + softer margins; FCFF starts ~$20B and grows ~2% with a higher discount rate.
  • Base: $65 real Brent mid-cycle + 10-year average margins; FCFF starts ~$27B (2025E) and grows ~6% through 2030.
  • Bull: stronger commodity deck (e.g., $75 real Brent) + better margins; FCFF starts ~$38B with moderate growth and a slightly lower discount rate.
Glossary
  • FCFF: Free cash flow to the firm (unlevered). Here approximated using company-reported free cash flow, with minor interest adjustments ignored for simplicity.
  • Net debt: Total debt less cash & equivalents (excluding restricted cash).
  • Terminal value: Value of cash flows beyond the explicit forecast period, modeled as a perpetuity growing at terminal growth.
