Valuation
Valuation · two methods
Earnings Power & Asset Floor
Two intrinsic-value methods and a tangible asset floor — deterministic, not price forecasts or recommendations.
Micron Technology Inc (MU): A conservative earnings-power estimate, $26–$56 / sh; today’s price sits above it (price $976 as of 2026-07-02).
Capex is in a steep ramp (heavy build-ahead investment) — owner earnings carry extra uncertainty, so read the value range with that caveat.
Model cautions
- Owner-earnings yield diverges sharply from the 10-year Treasury (over 300 bps).
- The DCF result diverges from a zero-growth sanity check (over 50%).
- Growth nearly matches the discount rate — the estimate is sensitive to assumptions.
An observation from two valuation methods — not investment advice, not a buy/sell signal, and not a price target.

Graham earnings-power value (normalized NOPAT)$34.37 – $40.10 / sh
Normalized NOPAT = average operating margin over the years shown × latest-year revenue × (1 − normalized tax); then + D&A − maintenance capex (write A). Unlevered (pre-interest, attributable to all capital). Capitalized at the 9–11% rate band (read as a WACC proxy). Enterprise → equity bridge applied: + cash − total debt.
Years: 2025, 2024, 2023, 2022, 2021
v1 simplifications: Maintenance capex (degraded) deducted in full cash (write A): EPV = (NOPAT + D&A − maintenance capex) / WACC; no tax shield on the capex term. Capex doubled within two years (AI-hog rule): maintenance capex floored at 50% of current capex; EPV is correspondingly pressed down. Only one maintenance-capex method available; estimate is degraded. Capex doubled within two years (AI-hog rule): flagged; the spike is treated as growth, not maintenance — owner earnings carry extra uncertainty. Share-based compensation is left as a real expense (not added back).
Buffett owner-earnings value$21.80 – $26.65 / sh
Owner earnings = average net income + average D&A − maintenance capex (zero-growth floor; no ΔNWC). Levered (starts from net income, already after interest — an equity-holder stream). Capitalized at the 9–11% rate band (read as a cost-of-equity proxy). No enterprise→equity bridge: the capitalized result is already equity value (subtracting debt would double-count interest).
Years: 2025, 2024, 2023, 2022, 2021
v1 simplifications: Owner earnings = net income + D&A − maintenance capex (degraded); the working-capital change is excluded (maintenance ΔNWC ≈ 0; growth ΔNWC is carried in growth value, not double-counted). Capex doubled within two years (AI-hog rule): maintenance capex floored at 50% of current capex. One-time items are not separately normalized (multi-year averaging smooths them partially). Share-based compensation is left as a real expense (not added back); see the SBC/OE disclosure. Capitalized at the same 9–11% band as a cost-of-equity proxy (theoretically the cost of equity is higher; v2 simplification, v3 to refine).
Reproduction value = tangible net assets $52.56B + capitalized R&D $10.19B（FY 2025, 2024, 2023, 2022, 2021） = $55.78 / sh. Reproduction value = tangible net assets (equity − goodwill − intangibles) + capitalized R&D (5y straight-line), ÷ diluted shares.
Moat reading: Franchise test compares earnings power (EPV) against reproduction value (tangible net assets + capitalized R&D). EPV well above reproduction value signals a moat; near it, a commodity; below it, value destruction. A directional reading, not a verdict.
Growth value gated to zero — no moat / ROIIC ≤ WACC, so no growth value is credited.
Window FY 2025, 2024, 2023, 2022, 2021 · discount band 9%–11% · normalized tax 12% (Average effective tax rate over 5 year(s), capped at the statutory 21%.) · diluted shares.
Owner-earnings DCF: growth g₁ 10% · OE FY 2025, 2024, 2023, 2022, 2021 · Discount band: 8.98%–12.00% (DGS10 +4.5% to a 12% strict end, as of 2026-07-01). No enterprise→equity bridge: owner earnings already flow to shareholders (post-interest), so no net cash is added and no debt subtracted — matching the engine owner-earnings lamp.
