Graham earnings-power value (normalized NOPAT)

Normalized operating earnings net of maintenance capex are non-positive over the years shown; earnings power cannot be capitalized.

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: 2026, 2025, 2024, 2023, 2022

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. Maintenance-capex methods diverge by 481% (> 50%); estimate is degraded. Share-based compensation is left as a real expense (not added back).

Buffett owner-earnings value

Normalized owner earnings are non-positive over the years shown; earnings power cannot be capitalized.

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: 2026, 2025, 2024, 2023, 2022

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). 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).
