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 先進光 do? Company profile

光電業；精密光學鏡頭與電子零件 上櫃

Overview

Business

先進光主要從事各類光學鏡片及鏡頭之設計、開發、製造、加工與銷售，以及指紋辨識模組、觸控相關模組與車用配件。產品涵蓋筆記型電腦與平板鏡頭、智慧型手機鏡頭、數位攝影機/數位相機鏡頭、光學式多點觸控螢幕鏡頭、條碼機與多功能事務機鏡頭、車用鏡頭、監控鏡頭、醫療與機器視覺、VR/AR、生物辨識等。2024年度公司揭露營收為新台幣42.78305億元，其中光學產品29.47602億元、占68.90%；電子零件產品13.30703億元、占31.10%。公司說明目前營收仍以筆電鏡頭與指紋辨識模組為大宗，並往車用、無人空拍機、安控等利基應用拓展。法說資料顯示 NB 鏡頭全球市占里程碑約65%至77%，2025年法說簡報列示77%作為 NB Lens Worldwide Market Share/Milestones。產能方面，台中廠負責模具、塑膠鏡片射出、鍍膜與自動化組裝，塑膠鏡片產能約1.2億片/月、鏡頭組裝約1,500萬顆/月、塑膠黑料約3,000萬件/月；越南胡志明廠負責玻璃鏡片研磨、自動定芯、鍍膜與組裝，玻璃鏡片約250萬片/月、鏡頭組裝約700萬顆/月；中國鎮江廠鏡頭組裝約800萬顆/月；集團鏡頭總產能約3,000萬顆/月。主要商業模式為與全球 NB、消費電子、車用與工業應用品牌/模組客戶共同開案，提供光學設計、模具、射出/研磨、鍍膜、組裝與 ODM/OEM 製造服務。媒體與產業資料列舉其 NB 客戶包含宏碁、華碩、戴爾、惠普、聯想、蘋果等；數位相機鏡頭曾供貨 Olympus；車用布局透過耀崴等子公司切入環景、電子後視鏡、DMS等，部分客戶與認證案屬媒體揭露，非全部可由官方年報逐一確認。

Outlook 2025–2028

2025年：月營收資料顯示全年合併營收約新台幣43.17392億元，年增約0.92%，營收維持高檔但獲利承壓；法說/媒體資訊指出前三季毛利與營業利益較2024年下滑，主要壓力來自客戶要求供應鏈移轉、越南擴產與車用布局前期成本。2025年成長主軸為 NB 鏡頭基本盤、AI PC/人臉辨識帶動單機鏡頭與指紋/觸控零組件增加、車用鏡頭逐步放量，以及越南「非中非台」供應鏈需求。2026年：公司於法說與新聞中表示將上修資本支出，規劃至少約新台幣20億元，投向越南新廠、廠房與設備，並在越南新增觸控與指紋辨識相關產線；越南新據點預計2026年中加入營運。車用方面以玻璃鏡片、環艙/環景、環境偵測與駕駛疲勞偵測 DMS 為重點，目標提升車用營收比重；但同時需面對 DRAM 漲價與缺貨可能壓抑 NB 出貨、客戶議價、折舊增加與資金成本壓力。2027年：可觀察越南新產能爬坡、車用客戶認證轉量產、科雅指紋/觸控模組在更多 PC 品牌量產、美系/亞洲車用與機器人/IoT專案的實際營收貢獻；法說資料提到影像 IC、Meta Lens、AR 眼球追蹤微型鏡頭、機器人觸覺 ForcePad 等新產品規劃，但量產時程與商業化仍屬不確定。2028年：若 AI PC、車用座艙感測、自動駕駛/ADAS、機器視覺與 AR/VR 應用持續成長，公司有機會從單純 NB 鏡頭供應商轉向多元光學與感測模組供應商；主要挑戰為筆電鏡頭標準化與價格競爭、車用認證週期長、越南擴產利用率、折舊與負債壓力、客戶集中、匯率與原料價格波動、專利/技術競爭、以及中國與日本光學廠競爭。2027-2028屬基於既有產品路線與產業趨勢之推估，尚無公司明確量化財測。

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.
