Optimistic top

Cactus Inc - A (WHD): A conservative value band $20–$130 / sh (zero-growth floor to growth-capped optimistic top); central read about $105. Today’s price sits below that band (price $62 as of 2026-10-16).
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
Buybacks over the years shown roughly only offset stock-based-compensation dilution — read them as maintaining the share count, not a net return of capital.
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 $30.52 – $129.77 · Greenwald zero-growth $38.80 · zero-growth base $38.80 · reproduction $8.77
Moat Franchise (moat) · terminal value 33% of present value · owner-earnings yield 4% vs 10Y 5.1%.
Graham earnings-power value (normalized NOPAT)$32.71 – $38.80 / 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 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). 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$20.09 – $24.56 / 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, 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 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 $603.85M = $8.77 / 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 2024, 2023, 2022, 2021 · discount band 9%–11% · normalized tax 18% (Average effective tax rate over 5 year(s), capped at the statutory 21%.) · diluted shares.
Owner-earnings DCF: growth g₁ 20% · OE FY TTM 2026-06-30, 2024, 2023, 2022, 2021 · Discount band: 9.60%–12.00% (DGS10 +4.5% to a 12% strict end, as of 2026-10-15). 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 13.6% a year in owner-earnings for the next few years. Revenue actually grew 29.2% a year.
Below what it has already done.
Roughly, the price needs its historical revenue growth to run about 5 more years to hold up.
