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 有成精密 do? Company profile

光電業;半導體製程設備零組件;太陽能模組與能源整合服務 臺灣證券交易所上市

Overview

有成精密股份有限公司,股票代號4949,為臺灣證券交易所上市普通股,非ETF/ETN/權證等非營運證券。公司成立於2003年11月5日,原名有成精密材料股份有限公司,早期從事半導體機台耗材買賣,後續擴展至真空零組件維修、半導體設備零組件開發製造,以及太陽能模組品牌與能源整合服務。總部位於新竹市東區公道五路二段180號4樓。董事長兼總經理為陳思銘,發言人為徐龍耀。公司曾於2010年登錄興櫃,2018年因組織與長期發展規劃終止興櫃,後於2024年5月9日轉上市掛牌;櫃買中心公告同日終止興櫃買賣。公開資料顯示資本額約新台幣6.77億元;員工規模公開來源有差異,台灣就業通列示約400人,因非最新年報口徑,僅作參考。主要股東名冊截至2025年3月30日,前十名包含陳逸菁5,157,736股、持股7.62%;建利投資3,236,162股、4.78%;忠易投資2,962,584股、4.38%;陳思銘2,404,361股、3.55%;黃俊祥2,402,000股、3.55%;陳宜君1,911,314股、2.82%;陳林彩茹1,862,634股、2.75%;匯豐台灣商銀受託保管英商高盛國際公司投資專戶1,690,208股、2.50%;順源投資1,600,762股、2.36%;鄭國宏1,473,116股、2.18%。

Business

公司為雙主軸營運:一是半導體製程設備關鍵零組件,二是新能源。半導體事業聚焦離子植入機、化學氣相沉積機台等設備耗材與關鍵零組件,產品包含離子電弧室、光束線相關零件、絕緣件、電極、孔徑件、燈絲、夾鉗、CVD用Carrier Ring、Robot Paddle、EPD Window等,並提供組件開發、零件改善設計、翻修、維修、駐廠或快速支援服務。商業模式偏向晶圓廠設備耗材與維修服務,透過客製化、材料加工、表面處理、良率與稼動率改善方案提高黏著度。新能源事業包含WINAICO自有品牌高效太陽能模組、太陽能系統建置、儲能應用工程、智慧能源管理、綠電供應與企業能源轉型方案。公司自2008年前後切入太陽能自有品牌,WINAICO外銷歐洲、澳洲、美國等市場,證交所文章指出模組外銷全球29國、合作近900個綠能安裝商夥伴,外銷比例約75%至85%。2022年興櫃資料顯示當時太陽能模組營收25.36億元、占81.06%,半導體設備零組件5.92億元、占18.94%;但2024至2025年公司營收結構已明顯朝半導體提高,第三方研究與媒體資料稱2024年半導體比重約43%、2025年半導體收入約12.96億元並成為主要獲利引擎,該比重非公司年報逐項揭露口徑,需保守看待。公司2025全年合併營收約23.89億元,2026年1至5月累計營收約14.10億元、年增明顯,反映半導體與新能源需求同步回升。主要終端應用包括晶圓製造、成熟與先進製程、車用IC、AI與高效能運算相關半導體產能,以及住宅、商用、工廠屋頂、漁電共生、企業綠電與儲能案場。

Outlook 2025–2028

2025至2028年展望可分三條主線。第一,半導體設備耗材受惠AI、高效能運算、先進製程與成熟製程持續投資。證交所資料指出2024至2026年全球新建晶圓廠帶動離子植入機零組件與耗材需求成長;有成已從90奈米一路服務到2奈米相關產品,並取得車用IC製造原廠供應鏈資格,產品線也延伸至薄膜沉積與化合物半導體應用。若全球晶圓廠資本支出維持高檔,設備耗材、翻修、改善設計與快速交期服務將支持較穩定毛利。第二,新能源業務從單純模組品牌銷售轉向光儲整合、企業能源轉型、儲能與智慧能源管理。歐洲住宅型太陽能、澳洲市場、企業用電大戶、碳關稅與淨零要求將支撐長線需求;公司已布局太陽能系統、儲能、EMS與綠電供應,若能從一次性模組銷售升級為專案與服務收入,營收品質有機會改善。第三,營收結構改善與國際化。2024年太陽能市場價格下行使公司營收下滑,但半導體比重提高有助毛利率修復;2026年1至5月累計營收年增約35.65%,顯示回升動能。主要風險包括:太陽能模組全球價格競爭與中國供給過剩、歐洲補貼與利率政策變動、匯率波動、海外庫存與通路風險、半導體景氣循環與客戶資本支出延後、關鍵客戶集中、精密加工產能與良率瓶頸、材料與設備供應交期,以及新廠或擴產投資未能如期轉化為訂單。2027至2028年的能見度低,除已揭露的半導體產品延伸與光儲整合方向外,具體營收或獲利數字不宜推估。

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.
