Malibu Boats Inc - A (MBUU): A conservative value band $8 / sh (zero-growth floor to growth-capped optimistic top); central read about $1. Today’s price sits above that band (price $27 as of 2026-09-03).
The middle figure is the main read. The right end is the optimistic case under the same conservative caps — not an absolute ceiling.
- Recent earnings are below the multi-year average, so the band uses the lower run-rate.

Method & numbers
Model cautions
- Owner-earnings yield diverges sharply from the 10-year Treasury (over 300 bps).
A conservative intrinsic-value band (zero-growth floor to growth-capped DCF) plus a tangible asset floor — not investment advice, not a buy/sell signal, and not a price target.

Graham earnings-power value (normalized NOPAT)$-1.60 – $-0.92 / 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 (ok) deducted in full cash (write A): EPV = (NOPAT + D&A − maintenance capex) / WACC; no tax shield on the capex term. Share-based compensation is left as a real expense (not added back). Operating margin is below its multi-year average (cyclical/declining): normalized margin capped at the latest year — no peak-margin capitalization (audit #2).
Buffett owner-earnings value$1.10 – $1.27 / 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 13.0–15.0% band (9–11% base + 4.0pp leverage premium). 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: Net income is below its multi-year average (cyclical/declining): normalized owner earnings anchored to the latest year — no peak-earnings capitalization (audit #2). Owner earnings = net income + D&A − maintenance capex (ok); 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 9–11% base band plus a 4.0pp leverage premium (cost of equity rises with leverage — MM Proposition II). Net debt is about 28.4 years of owner earnings, adding 4.0pp of cost-of-equity risk premium.
Reproduction value = tangible net assets $149.79M = $7.74 / 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 on both AV_conservative (tangible + capitalized R&D) and AV_reproduction (conservative + acquired-reset proxy). Both must clear the franchise multiple for a moat signal; near it, a commodity; below it, value destruction. A directional reading, not a verdict.
Growth value gated to zero — no moat or ROIIC ≤ WACC, so no growth value is credited.
Window FY 2025, 2024, 2023, 2022, 2021 · discount band 9%–11% · normalized tax 21% (Average effective tax rate over 5 year(s), capped at the statutory 21%.) · diluted shares.
Baseline 9%–11%, net debt ≈ 28.4 years of owner earnings → +4.0pp cost-of-equity premium → effective 13.0%–15.0%.
Owner-earnings DCF: growth g₁ 0% (history declining → capped at 0) · OE FY 2025, 2024, 2023, 2022, 2021 · Discount band: 13.29%–16.00% (DGS10 +4.5% to a 12% strict end, each +4.00pp for leverage premium, as of 2026-09-02). 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.
