Consensus Spread
Market Consensus: 可驗證的直接 EPS 只有元富 FY2026/27E NT12 為 NTM proxy,非券商 FY2028E 預估;資料更新前不提高確信度。
P/E Rationale
- 估值基準: 估值以 holding-company discount、矽晶圓子公司獲利修復及資產價值為共同 anchor;歷史 P/E 基準未獨立驗證。
- Bear: 下行由 EPS 未達、估值回落或兩者同時觸發。
- Base: 只採情境中明示的 EPS 與 P/E,不直接搬用券商目標價。
- Bull: 需要產能、產品組合與需求同時優於 Base。
Investment Thesis
- 中美晶的核心不是純矽晶圓 beta,而是持有環球晶 46.64% 之外,再加上其他轉投資的資產重估;元富在 4/22 的估算中,主要持股市值合計 NT85.3bn,反映控股折價。[元富, Apr 2026] 矽晶圓復甦的高階/12 吋端由環球晶帶動,但本頁不能把集團 NAV 與可實現獲利混為一談。收盤 NT$216.5 高於 5/20/60/240 日均線。[玉山, May 2026;FinMind, Oct 2026]
Model assumptions & uncertainty
- Forward earnings basis: NTM / FY2027E proxy at 2027-12-31 target date
- Evidence quality: Medium; see Consensus Spread and sources for estimate dispersion / evidence gaps.
- Freshness: Latest direct evidence through 2026-07-15.
- Fallback: Bear NT8 × 12x; Base NT12 × 18x; Bull NT15 × 22x. Base requires both earnings recovery and partial holding-company discount narrowing.
- Sensitivity: Demand conversion, capacity/price realization and forward EPS estimate convergence are the key sensitivities.
