Method & numbers
· reproduction $5.00
Moat Below asset base.
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: 2025, 2024, 2023, 2022, 2021
v1 simplifications: Maintenance capex unavailable → degraded to the v1 simplification (maintenance capex = D&A, so the depreciation add-back nets to zero). 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: 2025, 2024, 2023, 2022, 2021
v1 simplifications: Maintenance capex or D&A unavailable → degraded to normalized net income (= average net income over the years shown). 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 $1.92B = $5.00 / sh. Tangible net assets = shareholders' equity − goodwill − intangibles, ÷ diluted shares (no R&D history to capitalize).
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 9% (Average effective tax rate over 5 year(s), capped at the statutory 21%.) · diluted shares.
