Graham earnings-power value (normalized NOPAT)$88.15 – $117.69 / 股
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.
年份：TTM 2026-06-30, 2024, 2023, 2022, 2021
v1 简化：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 156% (> 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$101.87 – $123.49 / 股
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).
年份：TTM 2026-06-30, 2024, 2023, 2022, 2021
v1 简化：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 156% (> 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.
资产地板：Reproduction value = tangible net assets + acquired-intangible reset proxy, ÷ diluted shares; tangible net assets alone are negative for this asset-light franchise (no R&D history to capitalize).
护城河读数：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. A directional reading, not a verdict.

价格在赌什么
现价把公司未来几年的 owner-earnings 年增定在 16.4%；公司过去营收年增 1.3%。
市场要它明显快过自己一贯的水平。
价值带信心不足时仍可对照：这里只说明市场在赌多快，不把它当成「确认便宜」。
