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.

What does 東台 do? Company profile

電機機械；工具機、PCB加工設備、半導體與高階製造設備台灣證券交易所上市

Overview

4526 對應東台精機股份有限公司，證券簡稱東台，為台灣證券交易所上市普通股。公司成立於 1969 年，總部位於高雄市路竹區路科三路 3 號，高雄科學園區；2000/09/28 上櫃，2003/09/15 上市。董事長兼總經理為嚴瑞雄。公開資料顯示實收資本額約新台幣 25.48 億元，發行普通股約 254,826,461 股。公司 2024 年年報揭露 2024 年合併營收 57.39 億元、年減 25%，合併毛利率 9%，歸屬母公司稅後淨損 9.07 億元，每股虧損 3.56 元；2025 年營運資料依公開資訊與股市資料顯示全年營收約 53.60 億元、EPS 約 1.81 元，但此數據來自股市資訊彙整網站，仍應以正式年報與財報為準。員工規模方面，2024 年年報列示截至 2025/03/31 合計 1,380 人，其中製造生產 740 人、業務售服 243 人、後勤行政 245 人、研發設計 152 人。主要股東與董監持股以嚴氏家族相關投資公司為核心，公開資料可見三新股份有限公司約 12,326,080 股、4.84%，瑞秀投資股份有限公司約 8,118,693 股、3.19%，嚴瑞雄個人約 5,480,200 股、2.15%，另有燦英投資、弘邁、宇源、偉玲投資等董事席次或持股；更早年報曾揭露三新投資、瑞秀投資、三新、燦英投資、嚴瑞雄、瑟正璐投資、偉玲投資、弘邁、東捷科技等為重要持股者。公司為東台集團核心公司，關係企業涵蓋台灣、中國、法國、奧地利、荷蘭、日本、泰國、馬來西亞、越南、美國、墨西哥等地，主要子公司或關係企業包括東鋒機械自動化、亞太菁英、譁泰精機、榮田精機、東曄精密、蘇州東昱、PCI、Anger Machining 等。

Business

東台以工具機與先進製造設備為核心，產品線包括專用機、CNC 車床、綜合加工中心機、臥式與立式加工中心、車銑複合機、搪銑床、PCB 鑽孔機、PCB 成型機、雷射鑽孔與雷射加工設備、金屬積層製造設備、智慧製造與整線整廠 Turnkey 解決方案。公司網站稱其具高雄與蘇州生產基地，並有超過 85 個全球銷售服務據點；東台每年投入約 3% 至 5% 研發預算，跨足超音波輔助加工、雷射加工、金屬 3D 列印等技術。2024 年產品營收比重據 MoneyDJ 彙整公司法說資料：綜合加工中心機約 46%、電腦數值控制車床約 20%、印刷電路板加工機約 5%、專用機約 10%、維修及整修約 16%。2024 年銷售地區約內銷 15%、外銷 85%，其中中國大陸約 36%、歐洲約 27%、亞洲約 18%。商業模式以設備研發設計、組裝製造、客製化專案、整線整廠輸出、售後維修與整修服務為主；年報指出公司為客製化設備研發設計、製造與銷售公司，部分機台設備採協力廠合作生產，零件與關鍵模組則由公司或供應鏈製作。終端應用涵蓋汽機車與新能源車、航太、能源、軌道交通、PCB與高階載板、AI伺服器板、高階封裝、第三代半導體硬脆材料加工、醫療、模具與一般金屬加工。2024 年資料顯示最近兩年度無單一客戶占銷貨淨額超過 10%，因此客戶集中度不高但客戶名稱揭露有限。

Outlook 2025–2028

2025 至 2028 年展望屬中期推估，能見度以公司已揭露策略與產業趨勢為主。成長動能包括：一、全球工具機在 2024 年出口下滑後，公司年報預期 2025 年後隨製造業復甦逐步回溫，印度、東協、美洲與供應鏈重組帶來新產能投資需求。二、公司 2025 年經營方針聚焦智慧製造、整線整廠解決方案、主力機種銷售、新應用產業，以及新能源車、半導體、載板產業布局。三、PCB 高階應用受 AI 伺服器、高階載板、車用板、5G 應用推動，東台已開發多軸獨立 CCD 鑽孔機與成型機，對應 AI 伺服器板背鑽、對鑽、高階載板基板加工及 24/7 自動化生產。四、半導體設備布局是重要選項，年報揭露東台運用切、磨、拋技術，開發晶圓基板研磨機與高階封裝用刨平機，適用碳化矽晶圓、硬脆材料與高階封裝平坦化；公司亦提到切入半導體供應鏈製造需求並取得相關成果。五、航太、電動車、軌道交通、氫能源與大型工件加工需求，可由亞太菁英、榮田、PCI、Anger 等集團資源整合接單。六、金屬積層製造與半導體設備零組件代工若能放量，將提高高附加價值產品占比。主要風險包括：全球景氣與資本支出循環仍弱、工具機需求復甦速度不確定；日系與歐系品牌在高階市場夾擊，中國低價設備在中低階市場競爭；匯率、利率、中美貿易戰、俄烏戰爭、紅海危機與地緣政治可能影響訂單與交期；鋼鐵、鋁、鎳、控制器、線性傳動、精密軸承等原物料與關鍵零組件價格與交期波動；半導體設備驗證週期長、客戶認證與量產導入不確定；人才與技術斷層可能限制研發速度。整體而言，2025-2028 的關鍵觀察指標為 PCB 與半導體設備營收占比、在手訂單、毛利率修復、海外市場接單、研發成果商業化、以及是否能將客製化專案轉為標準化與模組化產品。
