Zero-growth floor

Central IV

$6

Optimistic top

$15

Malibu Boats Inc - A (MBUU): A conservative value band $15 / sh (zero-growth floor to growth-capped optimistic top); central read about $6. Today’s price sits above that band (price $28 as of 2026-07-20).

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

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.

Owner-earnings DCF $5.22 – $6.92 · Greenwald zero-growth $15.01 · zero-growth base $15.01 · reproduction $15.01

Moat Below asset base · terminal value 37% of present value · owner-earnings yield 2% vs 10Y 4.5%.

Graham earnings-power value (normalized NOPAT)$9.41 – $11.29 / 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: 2024, 2023, 2022, 2021, 2020

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$5.69 – $6.96 / 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: 2024, 2023, 2022, 2021, 2020

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% band as a cost-of-equity proxy; no leverage premium applied (net cash or debt within the no-charge range).

Reproduction value = tangible net assets $295.52M = $15.01 / 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 2024, 2023, 2022, 2021, 2020 · discount band 9%–11% · normalized tax 19% (Average effective tax rate over 5 year(s), capped at the statutory 21%.) · diluted shares.

Owner-earnings DCF: growth g₁ 0% (history declining → capped at 0) · OE FY 2024, 2023, 2022, 2021, 2020 · Discount band: 9.05%–12.00% (DGS10 +4.5% to a 12% strict end, as of 2026-07-17). 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.

What the price is betting

Today's price pencils in about over 30.0% (outside the usual range) a year in owner-earnings for the next few years. Revenue actually grew 2.5% a year.

The market wants it well ahead of its own track record.

Even when the value band is low-confidence: use this to see what the price assumes — not as a cheapness confirmation.
