Central IV

$239

Optimistic top

$295

Eagle Materials Inc (EXP): A conservative value band $123–$295 / sh (zero-growth floor to growth-capped optimistic top); central read about $239. Today’s price sits below that band (price $199 as of 2026-08-25).

The middle figure is the main read. The right end is the optimistic case under the same conservative caps — not an absolute ceiling.

Method & numbers

Model cautions

  • Growth nearly matches the discount rate — the estimate is sensitive to assumptions.

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 $139.66 – $294.76 · Greenwald zero-growth $157.77 · zero-growth base $157.77 · reproduction $29.46

Moat Franchise (moat) · terminal value 24% of present value · owner-earnings yield 7% vs 10Y 4.7%.

Graham earnings-power value (normalized NOPAT)$122.89 – $157.77 / 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, 2022, 2021, 2020

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 93% (> 50%); estimate is degraded. Share-based compensation is left as a real expense (not added back).

Buffett owner-earnings value$127.36 – $155.66 / 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: TTM 2026-06-30, 2022, 2021, 2020

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). Maintenance-capex methods diverge by 93% (> 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% 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 $915.97M = $29.46 / 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.

Assumes a wide moat · competitive-advantage period ≈ 20 years (earnings intact, ROIC stable over history).

Growth value not assessable — No positive growth reinvestment in the matured window, so ROIIC cannot be computed.

Window TTM 2026-06-30, FY 2022, 2021, 2020 · discount band 9%–11% · normalized tax 21% (Average effective tax rate over 1 year(s), capped at the statutory 21%.) · diluted shares.

Owner-earnings DCF: growth g₁ 7% · OE FY TTM 2026-06-30, 2022, 2021, 2020 · Discount band: 9.20%–12.00% (DGS10 +4.5% to a 12% strict end, as of 2026-08-24). 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 4.7% a year in owner-earnings for the next few years. Revenue actually grew 7.1% a year.

Below what it has already done.

Roughly, the price needs its historical revenue growth to run about 8 more years to hold up.
