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

工信是以重大公共工程與土木營造為核心的綜合營造公司，主要承攬道路、橋樑、隧道、碼頭、捷運、鐵路、港灣、疏浚、電廠周邊工程、建築工程與地質鑽探等工程，並從事工程相關材料買賣及進出口。113年度營收結構為工程合約新台幣69.81億元、占98.34%，不動產銷售1.17億元、占1.65%，其他82.2萬元、占0.01%，總營收70.99億元。主要服務項目涵蓋土木工程、海事工程、橋梁工程、建築工程、天然氣火力發電廠周邊工程、捷運工程；在建或重要工程包括淡江大橋及其聯絡道路、木瓜溪橋改建、台中電廠燃氣機組循環水抽水機房及暗渠、臺北港南碼頭S04/S05相關工程、花東地區鐵路雙軌電氣化CB02標、台北捷運環狀線北環段、高雄捷運黃線YC02與YC03標、空軍H007工程等。商業模式以公共機關或公民營機構發包之工程標案為主，透過公開招標、最有利標、統包工程、聯合承攬或協力廠商分包取得案源與執行；公司以包工包料為原則，自行採購鋼筋、砂石、混凝土、土方、油料與特殊材料。113年度主要銷貨客戶為交通部公路總局35.45%、台灣電力公司20.28%、台灣港務公司13.98%、交通部鐵道局5.95%；2025年全年營收約90.38億元，年增27.32%，2026年5月累計營收約45.59億元，累計年增16.04%。

Outlook 2025–2028

2025至2028年展望以公共工程在手案、政府基礎建設預算與交通/能源/港灣工程需求為主軸。成長動能包括：一、公司113年度年報揭露114年度以公路、軌道運輸、橋梁、隧道、港埠等公共工程為主要追蹤目標，擬訂114年度業務承攬金額80億元未稅；二、2025年全年營收90.38億元、年增27.32%，2026年前5月累計營收45.59億元、年增16.04%，顯示在手工程認列推升營收；三、重大合約工期橫跨2026至2033年，包含台中電廠燃氣機組工程至2026年11月、臺北港南碼頭至2027年5月、空軍H007至2027年12月、花東雙軌電氣化CB02至2028年5月、台北捷運北環段至2032年4月、高雄捷運黃線YC03與YC02至2033年，將提供中期營收能見度；四、公司短期規劃持續以公共工程為主，適度擴大建築工程承攬比例，並深化BIM、地質改良、隧道、港灣疏浚、PC化與即時監控等技術，長期則朝民間工程與海外大型工程承攬發展。產業趨勢方面，政府公共工程逐步採最有利標、統包最有利標與BOT/BT模式，有利具整合施工、設計、機電、財務與協力廠商管理能力的中大型營造商；軌道建設、水環境、綠能、城鄉建設與新南向基礎建設亦是潛在案源。主要風險包括營造業競爭激烈且甲級營造廠眾多、惡性低價搶標、營建物料價格波動、砂石/混凝土/鋼筋/油料成本上升、勞安與環保法規成本增加、居民抗爭或用地/環評延宕、定型化合約條款與工程爭議、公共工程驗收與估驗款時點造成現金流波動、海外或外商競爭，以及重大工程若發生工期、品質、設計變更或索賠爭議將影響毛利與評價。2026至2028具體獲利幅度仍高度取決於個案毛利率、工程進度、物調款、追加減與爭議處理，無足夠公開資料可精準預測。

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.
