Valuation
No usable market price is available, so this page does not place price on the value gauge.
Method & numbers
Price is at or below the reproducible tangible asset base ($32 / sh) — a rarer, harder floor.
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.
· reproduction $31.55
Moat Below asset base.
Graham earnings-power value (normalized NOPAT)
Normalized operating earnings net of maintenance capex are non-positive over the years shown; earnings power cannot be capitalized.
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
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).
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
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 debt or owner earnings is unavailable, so no adjustment is made.
Reproduction value = tangible net assets $403.93M = $31.55 / sh. Total book value (shareholders' equity ÷ diluted shares); intangibles not separated — goodwill/intangibles unavailable this period.
Moat reading: Franchise test compares earnings power (EPV) against reproduction value (tangible net assets + capitalized R&D). EPV well above reproduction value signals a moat; near it, a commodity; below it, value destruction. Dual reproduction test unavailable (intangibles not separated). 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 · discount band 9%–11% · normalized tax 0% (Average effective tax rate over 4 year(s), capped at the statutory 21%.) · diluted shares.
