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

太欣為台灣消費性 IC 設計廠,核心業務為積體電路研究發展、設計、製造與銷售,產品聚焦影像處理與數位影像擷取錄影系統單晶片,並延伸至 MCU、USB/數位電腦耳機 IC、無線充電控制晶片與 ASIC 晶片客製化設計服務。2024 年產品營收結構公開資料顯示,網路攝影機控制 IC 約占 70%,MCU 約占 10%,數位電腦耳機 IC 約占 20%;銷售區域約亞洲 79%、台灣 21%。主要產品應用包括行車記錄器、數位監控錄影、迷你攝影機、航拍與消費性錄影產品、手機或平板 Wi-Fi 控制的輕型錄影設備、汽車、家電、醫療與消費電子 MCU 應用、USB 低功耗耳機方案、BLDC 馬達控制、無線充電發射端控制晶片。商業模式以 IC 設計、委外製造、代理/客戶導入與技術服務為主;公開資料指出攝影機控制 IC 曾獲中國大陸車廠採用,也由韓國與中國大陸代理商導入全高清及雙路行車記錄器解決方案。2025 年 5 月起新增 ASIC 晶片開發委託設計服務,已簽一年以上長約,成為較穩定的營收來源之一。財務面,公司 2024 年營收約新台幣 1,391.2 萬元、歸屬母公司淨損約 4,384.3 萬元;2025 年全年月營收累計約 1,943.3 萬元,年增約 39.69%;2026 年第 1 季營收約 678 萬元、稅後淨損約 625.4 萬元、EPS 約 -0.04 元,2026 年前 5 月累計營收約 1,188.2 萬元、年增約 102.38%。公司仍屬小型、轉型中的 IC 設計公司,營收基期低、波動較大。

Outlook 2025–2028

2025 年公司重點在新舊產品線轉換、ASIC Design Service 導入與無線充電控制晶片開發。公開法說摘要指出,2025 年前三季營收逐季改善,主要受惠於 2025 年 5 月起新增的晶片客製化設計服務;公司亦預計 2025Q4 認列約新台幣 1,982 萬元退休金專戶結清收入,對短期損益有一次性正面效果。2026 年初至 5 月月營收年增明顯,但因基期低且第 1 季仍虧損,是否形成可持續獲利模式仍待驗證。2026 至 2028 年的主要成長動能推估包括:一、ASIC 設計服務若能延續長約並擴大客戶數,可改善過去產品銷售波動;二、WPC Qi2.0 MPP 磁吸式無線充電發射端控制晶片若完成開發並導入手機、智慧手錶、無線耳機與車載/醫療等應用,有機會成為新產品線;三、MCU 市場經歷庫存去化與價格競爭後,若電動車、物聯網、邊緣 AI、家電與醫療消費電子需求回溫,對公司 MCU 產品有間接受惠;四、內湖研發大樓擴建完工及後續資產活化若順利,可能改善資產使用效率。主要風險包括:營收規模極小、連年虧損與費用吸收能力有限;中國 MCU 與無線充電 IC 廠商低價競爭;既有攝影機控制 IC 與 DVR 產品成熟化;新產品認證、量產、客戶導入與毛利率不確定;ASIC Design Service 客戶集中度與合約續約風險;匯率、晶圓成本與委外製造交期風險。公司未公開具體 2026 至 2028 財測,以上展望中超過已公告內容者屬研究推估。

Supply Chain

Upstream
  • 晶圓供應商/晶圓代工廠 公開資料僅明確指出主要原料為晶圓,未確認個別供應商名單;太欣作為 IC 設計公司,營運上通常需依賴晶圓代工、封測與相關 EDA/IP 供應鏈。

  • 無線充電聯盟 WPC 非供應商且非台股掛牌公司;太欣正在開發相容 WPC Qi2.0 MPP 規範的無線充電發射端控制晶片,WPC 標準影響產品規格與認證門檻。
Downstream
  • 中國大陸車廠 公開資料稱公司攝影機控制 IC 獲中國大陸車廠採用,但未揭露具體客戶名稱;應用包括行車記錄器與汽車機面板操作系統相關錄影方案。
  • 韓國與中國大陸代理商 公開資料稱公司透過韓國與中國大陸代理商導入全高清及雙路行車記錄器解決方案;具體代理商未公開。
  • 手機、智慧手錶、無線耳機等可攜式裝置客戶 法說摘要指出 Qi2.0 MPP 無線充電發射端控制晶片目標市場為可攜式裝置,且已與中國大陸主要客戶前期溝通;客戶名稱尚未公開。
  • ASIC 晶片開發委託設計客戶 2025 年 5 月起新增 ASIC Design Service,並已簽一年以上長期合約;客戶名稱、產業別與是否上市櫃未公開。

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.
