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.

光電業；安控監控、智慧影像、車載安全、邊緣 AI 與工業電腦相關 台灣證券交易所上市

Overview

5484 對應慧友電子股份有限公司，英文名 EverFocus Electronics Corp.，為台灣證券交易所上市普通股，非 ETF、ETN、權證或特別股。公司成立於 1995 年 7 月 18 日；2001 年 3 月 16 日上櫃，2003 年 8 月 25 日轉上市。官方與資訊平台揭露總部/公司地址版本略有差異，近年公司官網列 HQ Office 為新北市新店區寶橋路 235 巷 134 號 1 樓，公開資訊/財報封面曾列新北市新店區寶橋路 235 巷 133 號 7 樓之 1；鉅亨網另列新北市深坑區北深路三段 270 巷 8 號 2 樓，推測與公司登記或過往資料更新時間差異有關。董事長為莊永順；總經理/經理人資料在不同來源出現莊永順、施皓榮、高誌鴻等版本，其中 114 年第一季財報簽章列董事長莊永順、經理人高誌鴻、會計主管林佳韋，故本研究採保守表述為管理職資料需以最新公開資訊觀測站公告為準。實收資本額約新台幣 668,010,000 元，普通股 66,801,000 股。員工規模：2025Q3 法說摘要列 worldwide 130 人；Investing.com 公司頁列 154 人，因統計口徑與日期不同，採 130 至 154 人區間。主要股東與董監持股：富邦/鉅亨資料顯示 2023 年莊永順持股約 10,655,686 股、約 15.95%，智新投資約 3,768,021 股、曹慧明約 1,707,541 股；財報狗顯示 2026 年 5 月董監持股比率約 24.68%，但主要股東最新完整名冊未能在公開網頁中完整驗證。公司有美國 Orange、東京、日本與中國深圳據點；公司官網揭露具 ISO9001、ISO14001、IATF 16949:2016 認證，且為 Intel IPA Gold Tier Member、NVIDIA Preferred Partner。

Business

慧友定位為智慧安控與智慧交通/工業視覺解決方案商，核心產品包含：1. 商用車安全與車載影像：MDVR、AI Mirror/Camera Monitor System、Mobile Camera、ADAS、BSD、DMS、車隊管理相關軟硬體；2. CCTV/安控監控：DVR/NVR/XVR、IP Camera、AHD/USB/3D 攝影機、中央監控與影像管理軟體；3. Edge AI 與工業電腦：NVIDIA Edge AI、Qualcomm Edge AI、Intel/ARM Embedded System、Automation and Control、Network Appliances、Embedded Computing、Vision Embedded System、GMSL Camera；4. AV over IP 與專業影音：Lecture Capture、Pro-AV Appliance、Capture Card 等。商業模式包含自有品牌 EverFocus 銷售、專案整合、OEM/ODM、車載與工業用客製化解決方案。終端應用涵蓋商用卡車與車隊、巴士與客運、自主機器人/AMR、特種車、交通與智慧城市、智慧零售、智慧製造、教育、政府與企業。2025Q3 法說摘要將 AI Vision 產品分為高階客製化相機與致動器、專業應用 AI 相機、高階 AI 運算視覺系統，並聚焦 Humanoid/Robot、Specialized Vehicle、AI Manufacturing。2025 前三季營收新台幣 329,308 仟元，較 2024 前三季 357,948 仟元年減 8%；區域結構為亞洲 59%、美洲 33%、歐洲 5%、中國 3%。2025 全年營收依 Yahoo/玩股網資料約新台幣 506,246 仟元，年增約 9.99%；截至 2026 年 5 月累計營收約 314,609 仟元，年增約 92.03%。2024 前三季產品結構第三方整理自法說資料為影像監控設備約 42%、工業電腦約 25%、智慧車載系統約 23%、其他約 10%，但此比重未在官方可直接擷取文字中完全驗證，列為參考。

Outlook 2025–2028

2025 至 2028 年展望：成長動能主要來自車載安全法規、商用車隊數位化、AI 邊緣運算、智慧製造與機器人視覺需求。短期來看，2025Q3 法說與 MoneyDJ 報導顯示第三季受惠半導體測試設備客戶拉貨增加，單季轉盈，且公司對 2025 年全年營收持平至小幅成長、2026 年工業用產品發酵持正向看法；實際 2025 全年營收年增約 10%，2026 年 1 至 5 月累計營收年增約 92%，顯示基期與訂單回補帶動明顯。中期產品路線包含 GMSL2 camera for robotics、ToF depth camera、Jetson Thor/Orin 機器人運算平台、AI NVR、MDVR、AI Mirror、Out-of-Band 管理、Intel/ARM/NVIDIA/Qualcomm edge AI 平台。若車隊安全、盲點偵測、DMS/ADAS、工業自動化與機器人視覺導入加速，慧友可望受惠於少量多樣、客製化與垂直應用整合需求。主要風險包括：公司規模小、營收波動大；近年多數年度仍虧損，2025Q1/Q2 虧損且 Q3 單季轉盈是否延續仍需追蹤；產品組合變動可能壓抑毛利率；安控與工業電腦競爭激烈；中國與國際品牌價格競爭；關鍵晶片/感測器供應與匯率波動；專案型與客製化訂單驗收時點造成營收不穩；若 AI/機器人產品路線未能放量，研發投入可能拖累獲利。2026 至 2028 的高成長假設屬推估，需以後續法說、月營收、毛利率與營業利益率驗證。

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.
