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.

Business

達航科技深耕 PCB 產業,主要業務包括 PCB 鑽孔機、成型機、清潔機、主軸(Spindle)、零件耗材、設備維修保養、雷射鑽孔與雷射加工服務,以及自有品牌設備。公司早期投入 PCB、LCD、被動元件、半導體產業相關設備代理銷售與維修保養,近年轉向自主研發製造高精密加工設備,包括雷射鑽孔機、高精度機械鑽孔機、成型機與精密主軸。營收結構方面,MoneyDJ 與 StockFeel 等資料顯示 2024 年營收以專業服務為主,專業服務約 63%(雷射鑽孔加工、機台維護保養),設備產銷約 34% 或設備約 33.5%,其他代理收入約 3% 至 3.5%。商業模式兼具設備銷售、售後維修保養、耗材零件、雷射鑽孔代工與產能支援服務;代工服務可協助 PCB、IC 載板或高階基板廠調節產能,設備銷售則受下游資本支出循環影響較大。主要客戶與終端應用包括 PCB 廠、IC 載板廠、高階 HDI、ABF 載板、AI 伺服器、高速運算、CPO/光電共封裝、新材料封裝、FPC、陶瓷、LTCC、矽晶圓、鋼板等微細加工應用。公開新聞曾點名服務客戶包含南電、欣興、景碩。

Outlook 2025–2028

2025 至 2028 年展望以高階 PCB、AI 伺服器、IC 載板、CPO 與精密雷射加工升級為主軸。2025 年營運已較 2024 年谷底回溫,2025 年全年營收約 7.4646 億元、年增約 12.2%;2026 年前 5 月營收約 3.57388 億元、年增約 49.7%,2026 年第 1 季營收約 2.10857 億元,但仍為稅後虧損、EPS 約 -0.21 元,顯示需求復甦與獲利改善仍需觀察。成長動能包括:AI 伺服器與高速網通推升高層數、高密度、高精度 PCB 與載板製程難度;ABF、HDI、CPO、新材料封裝與探針卡等精密加工需求提升雷射鑽孔、微孔、切割、挖槽等設備與代工需求;公司在台灣與日本研發據點、中國、韓國、東南亞服務網絡,有助接觸海外客戶與支援設備售後服務。2026 至 2028 年若下游 PCB/IC 載板資本支出恢復、專業服務稼動率提高、雷射平台產品通過更多客戶驗證,營運有機會逐步改善。主要風險包括:PCB 與載板產業景氣循環大、設備訂單遞延或取消、公司近年仍處虧損且固定成本壓力高、專業服務稼動率不足會壓縮毛利、客戶集中與少數大廠資本支出變化、雷射設備與精密主軸技術競爭、海外服務與匯率風險、AI/CPO 題材若未能轉化為實際訂單可能造成市場預期落差。2027 至 2028 的量化營收與獲利未見公司正式財測,故不做數字預估。

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.

This page is historical statistics for educational purposes and is not investment advice. Investing involves risk; past performance does not indicate future results. Assess and bear the risk yourself before trading.
