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.

Overview

光焱科技股份有限公司成立於2009年3月2日,總部位於高雄市路竹區路科五路96號1樓,位於南部科學園區高雄園區。公司於2023年11月29日公開發行、2024年3月18日登錄興櫃、2025年3月6日上櫃,證券代號7728,為普通股。董事長為柯歷亞,總經理為廖華賢;兩人為共同創業核心,年報揭露董事長兼營業長與總經理為配偶。依公開資料,實收資本額約新台幣1.3854億元、已發行普通股13,854,080股。員工規模依2024年年報截至2025年4月30日為86人,其中管理11人、研發15人、一般員工60人。主要股東基準日2025年4月5日為正亞投資有限公司26.55%、哈柏投資有限公司24.24%、中盈投資開發股份有限公司6.56%、台新國際商業銀行受託信託財產專戶3.70%、有本投資股份有限公司1.94%、余維斌1.91%、柯歷亞1.54%、台新綜合證券1.29%、邱敏鳳0.81%、張凱敦0.77%。公司透過Molly Ltd.、IRIS Tek Ltd.持有勝焱電子科技(上海)有限公司100%,上海子公司從事檢測分析儀器批發、進出口及技術服務。

Business

公司主要從事模擬光源、半導體光電轉換測試儀器、晶圓級光電檢測儀器之研發、設計、製造與銷售,核心能力為人造光源調製、光譜分析、光電轉換效率量測、軟硬體整合與客製化設備設計。2024年營收新台幣3.80116億元,產品結構為半導體光電轉換測試2.07556億元、占54.60%;模擬光源1.27059億元、占33.43%;晶圓級光電檢測2,031萬元、占5.34%;耗材與維修等其他2,519.1萬元、占6.63%。銷售地區以外銷為主,2024年外銷占95.82%,其中亞洲占86.18%、歐洲5.68%、美洲3.15%、其他0.81%,內銷占4.18%。主要產品應用於科學研究儀器、太陽能與鈣鈦礦材料研發、CIS影像感測器、LiDAR/SPAD/SiPM光感測器、環境光/接近光/3D感測器、矽光子與CPO接收器、半導體晶圓級WAT/CP/FT檢測。商業模式以高客製化、小量多樣設備與技術服務為主,透過自有研發、協力廠零組件加工、模組化設計、海外子公司與代理經銷通路服務科研與半導體客戶。年報揭露2024年沒有單一銷貨客戶超過10%;2023年曾有SCL占銷貨13.53%,但未揭露全名。2025年營收約新台幣3.6億元、年減6.16%,稅後淨利6,690萬元、EPS 4.92元,主要受美國關稅與訂單遞延影響,第四季訂單回升。

Outlook 2025–2028

2025年公司研發與產品主軸為CIS二代WL產線檢測光源、LiDAR光感測器產線FT檢測光源、CPO Receiver產研用高速檢測設備與CPO光波導檢測設備;公司揭露CIS進入量產階段、LiDAR完成產業化並開始小規模量產、矽光子與CPO從科研階段進入早期產業化。2025年營運實際受到美國關稅與客戶採購遞延影響,前三季較弱、第四季回升。2026年公司規劃開發CPO Receiver量產用高速檢測光源設備,並持續提升模擬光源、半導體光電量測與晶圓級檢測三大產品線;2026年6月公司表示部分案件訂單能見度可看三個季度以上,半導體業務第三季、第四季有機會出現新進展,下半年可能較具爆發性成長。2027至2028年展望屬推估:若AI資料中心高速傳輸、矽光子/CPO、CIS車用與工業影像、LiDAR、先進封裝與晶圓級光學檢測需求持續擴大,光焱有機會由科研儀器供應商進一步提高半導體產線設備占比;公司亦規劃強化AI與自動化技術整合,提升檢測準確性與效率。主要風險包括:客製化設備小量多樣造成規模化不易、科研市場通路封閉、專業人才招募困難、關稅與地緣政治造成訂單遞延、外銷比重高帶來匯率與區域需求波動、矽光子/CPO導入時程與客戶驗證進度不確定、晶圓級量產設備需面對國際設備大廠競爭。

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.
