Above fair value
$23 value estimate
Solaris Energy Infrastructur (SEI): A conservative earnings-power estimate, $23 / sh; today’s price sits above it (price $52 as of 2026-08-26).
- Capex doubled in two years, so maintenance is hard to pin down — read the band conservatively.
Zero-growth downside $23

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
- Capex doubled within two years: maintenance is floored then capped at D&A (OE may look optimistic); Greenwald growth value is closed — growth credit stays in the owner-earnings DCF only.
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)$3.70 – $10.11 / 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. Only one maintenance-capex method available; estimate is degraded. Capex doubled within two years (AI-hog rule): flagged; the spike is treated as growth, not maintenance — owner earnings carry extra uncertainty. Share-based compensation is left as a real expense (not added back).
Buffett owner-earnings value
Normalized owner earnings are non-positive over the years shown; earnings power cannot be capitalized.
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: 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). Only one maintenance-capex method available; estimate is degraded. Capex doubled within two years (AI-hog rule): flagged; the spike is treated as growth, not maintenance — owner earnings carry extra uncertainty. 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 debt or owner earnings is unavailable, so no adjustment is made.
Reproduction value = tangible net assets $727.41M = $23.31 / 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 — capex doubled within two years (AI-hog); growth credit stays in the owner-earnings DCF only.
