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

詠昇為訊號連接器、訊號傳輸線與客製化線材模組製造商，產品包括電子連接器、訊號傳輸線、Cable Assembly、Adapter、USB Type-C、USB 2.0/3.x、DisplayPort、DVI、VGA、KVM、LAN/Network/Patch、D-Sub、Mini Din、Wire Harness、RF Cable、Audio Cable、LVDS、光纖線材、防水連接器、工控用防水類產品、PCB Assembly/Dongle、PCBA 以及金屬端子加工。商業模式以客戶指定組件、客製化與利基型產品之設計製造代工為主，並透過自製關鍵零組件、金屬端子沖壓、自動化生產與檢驗設備降低成本與提升交期彈性。依公司 2026 年第一次法說會簡報，2025 年產品營收比重約為連接器 50%、連接線 35%、電子產品 4%、其他 11%；2025 年產品應用比重約為工控產品 30%、3C 產品 39%、非 3C 產品 20%、車用產品 3%、醫療產品 8%。依 2025 年第三季合併財報，2025 年前三季營收新台幣 587,922 仟元，其中連接器 301,535 仟元、線材成品 203,311 仟元、電子產品 23,917 仟元、其他 51,669 仟元、加工收入 7,490 仟元。終端應用涵蓋 TV 與顯示器、PC、通訊、工業電腦與設備、事務機、醫療設備、車用電子與智慧穿戴相關 IoT 應用。公司未在已查得公開資料中完整揭露主要客戶名稱，只以應用領域、客戶群廣與銷售區域分散描述。

Outlook 2025–2028

2025 至 2028 年展望以穩定本業、提高自製與自動化、擴大工控/醫療/車用/智慧穿戴等非單一消費性電子應用為主。成長動能包括：一、工控、3C、醫療與車用應用持續擴張，2025 年法說會已揭露工控、3C、非 3C、車用、醫療為主要應用結構；二、公司已導入 USB Type-C、USB3.0、防水 Type-C、防水型環狀連接器、工控用防水類產品等產品，後續可受惠高速傳輸、環保、高速、輕量化與防水連接需求；三、持續增加自動化生產與檢驗設備，有助於降低人力工時、提高效率並維持約 20% 毛利率水準；四、2025 年上曜集團與世紀民生入主後，集團表示將結合詠昇在連接器、智慧穿戴 IoT 與醫療應用的能力，形成資源整合、技術交流與市場聯動。財務基礎方面，2022 至 2025 年營收分別約為新台幣 817,754 仟元、828,349 仟元、794,532 仟元、782,351 仟元，2025 年營收較 2024 年小幅下滑；2025 年毛利率約 20.55%，稅後淨利約 25,154 仟元，EPS 約 0.73 元。2026 年 1 至 4 月累計營收新台幣 261,278 仟元，較去年同期減少 1.05%，顯示短期營運仍偏穩而非高速成長。主要風險包括全球景氣與消費/工控需求循環、銅材與塑膠等原料價格波動、匯率波動、連接器產業競爭激烈、客製化利基產品量產放大不確定性、車用與醫療認證導入時間、以及新集團整合後治理與策略執行成效。2027 至 2028 年具體財務預測未見公司正式量化指引，本段對中期成長動能屬依公司策略展望與產業趨勢之推估。

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.
