Branch inventory reconstruction
Accumulating holders Branches that accumulated shares during the window and still hold positive inventory; they are the absorbing side.
Distributing sellers Branches that built inventory earlier and have been selling it down; the remaining number estimates what has not cleared.
Net-short desks Trading-desk branches with negative inventory or net selling, often hedge, offsetting, or short-term flow. It is not automatically a bearish view.

力積電採 Open Foundry 營運模式,以先進記憶體、客製化邏輯積體電路與分離式元件晶圓代工為服務主軸,服務涵蓋晶片設計支援、製造服務、設備與產能分享。主要營業項目為各式積體電路及系統產品之生產、製造、測試、封裝,半導體設備零組件維修、開發、製造與銷售,以及特殊應用積體電路技術整合服務、矽智財設計與服務。依 2025 年報,2025 年營收新台幣 467.30113 億元,產品比重為邏輯暨特殊應用產品 61.11%、記憶體產品 38.89%;董事長致股東報告書另將全年營收貢獻拆為邏輯代工 61%、記憶體代工 37%、先進封裝 2%。邏輯暨特殊應用晶圓代工包含顯示驅動 IC、電源管理 IC、分離式元件、CMOS 影像感測器、嵌入式非揮發性記憶體等;記憶體晶圓代工包含 DRAM、Interposer 中介層與 Flash。終端應用包括電腦、通訊、消費性電子、車用電子與 AI 相關應用。2025 年銷售地區比重為內銷 50.74%、外銷 49.26%,其中亞洲 23.90%、美洲 18.41%、歐洲 6.95%。年報揭露 2025 年有一名未具名甲客戶占銷貨淨額 10.17%,單一供應商 A 廠商占進貨淨額 10.69%,但未揭露實名。

Outlook 2025–2028

2025 年公司營收 467 億元、年增 4%,但受銅鑼 P5 新廠尚未達經濟規模拖累,稅後虧損約新台幣 78 億元;公司在年報中稱 2025 年為營運谷底,2026 年將透過第四次轉型,聚焦 AI 相關成熟製程、利基型記憶體與先進封裝。成長動能包括:1. AI 伺服器與先進封裝帶動 PMIC、矽中介層、GaN、IPD 矽電容等需求;2. 3D AI Foundry、3D WoW Hybrid-Bonding 與四層 DRAM 堆疊已取得先進邏輯大廠認證,並往八層堆疊推進;3. 高密度電容 IPD 的 2.5D Interposer 通過國際大廠認證並開始送樣或導入量產;4. 與美光簽署策略合作意向書,美光擬以 18 億美元現金收購力積電苗栗銅鑼 P5 12 吋晶圓廠,交易預計 2026 年第二季完成且需監管核准,交易後美光將取得 P5 所有權並分階段導入設備,力積電則將 P5 設備與人員轉回大新竹廠區、汰換老舊設備及低毛利產品線,並承接美光 DRAM 晶圓後段製造 PWF,切入 HBM 先進封裝供應鏈;5. 與 Tata Electronics 的印度技術服務合作仍進行,2025 年報稱技術服務費已累計入帳 1.43 億美元。2026 年 4 月法說相關報導指出,DRAM 代工價格 2026 年 3 月大幅調高,漲價效益預期 6 月起對營收有雙位數以上貢獻;與美光合作的 1P 製程預計 2027 年第一季新機台搬入、2028 年上半年試產、下半年量產;PWF 產線預計 2026 年第三季機台搬入、第四季試產、2027 年第四季量產,目標月產能 2 萬片;WoW 四層堆疊可望 2027 年轉小量生產。主要風險包括成熟製程價格競爭、中國成熟製程擴產與國產化壓力、消費性電子復甦不確定、車用與工規半導體復甦緩慢、P5 交易需監管核准且搬遷/復線存在執行風險、先進封裝與新製程認證時程不確定、DRAM/NAND 景氣循環波動、匯率與資本支出壓力。

Method and limitations

  • All returns use adjusted close (etl:adj_close), already adjusted for dividends and splits.
  • Excess return is measured against the TAIEX total-return index (dividends included).
  • Valuation regime and percentile stats use an expanding own-history window (no future data).
  • Revenue-signal event dates align to the first trading day after the filing deadline, avoiding look-ahead.
  • Event samples may overlap in time; stats describe historical distribution only and are less reliable when samples are few.
