Generac Holdings Inc (GNRC): A conservative value band $39–$52 / sh (zero-growth floor to growth-capped optimistic top); central read about $40. Today’s price sits above that band (price $207 as of 2026-08-26).
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 $35.75 – $46.35 · Greenwald zero-growth $51.85 · zero-growth base $51.85 · reproduction $17.33
Moat Commodity-like · terminal value 35% of present value · owner-earnings yield 2% vs 10Y 4.7%.
Graham earnings-power value (normalized NOPAT)$39.32 – $51.85 / 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: TTM 2026-06-30, 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. Maintenance-capex methods diverge by 66% (> 50%); estimate is degraded. 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$38.88 – $47.14 / 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 9.4–11.4% band (9–11% base + 0.4pp leverage premium). No enterprise→equity bridge: the capitalized result is already equity value (subtracting debt would double-count interest).
Years: TTM 2026-06-30, 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 (degraded); the working-capital change is excluded (maintenance ΔNWC ≈ 0; growth ΔNWC is carried in growth value, not double-counted). Maintenance-capex methods diverge by 66% (> 50%); estimate is degraded. 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 0.4pp leverage premium (cost of equity rises with leverage — MM Proposition II). Net debt is about 3.8 years of owner earnings, adding 0.4pp of cost-of-equity risk premium.
Reproduction value = tangible net assets $550.61M + capitalized R&D $482.60M（FY 2026, 2024, 2023, 2022） = $17.33 / 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 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 TTM 2026-06-30, FY 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 ≈ 3.8 years of owner earnings → +0.4pp cost-of-equity premium → effective 9.4%–11.4%.
Owner-earnings DCF: growth g₁ 0% (history declining → capped at 0) · OE FY TTM 2026-06-30, 2024, 2023, 2022, 2021 · Discount band: 9.58%–12.42% (DGS10 +4.5% to a 12% strict end, each +0.42pp for leverage premium, as of 2026-08-26). 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.
Valuation basis: trailing twelve months to 2026-06-30 — latest 10-K plus unaudited 10-Q filings.
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 8.7% 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.
