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.

What does 嘉雨思-創 do? Company profile

半導體業/IC設計/高速傳輸介面IC 臺灣證券交易所創新板上市

Overview

6921 對應嘉雨思科技股份有限公司,為普通股而非 ETF、ETN、權證或特別股;證交所公告其普通股於 2025-12-23 在臺灣證券交易所創新板上市開始買賣。公司成立於 2020-01-02,總部位於新北市中和區連城路268號5樓之2,統一編號 83494520,英文名稱 LeRain Technology Co., Ltd.。董事長為朱德祥,總經理與發言人為高妙斌。依上市公司整合資訊與股市資料,實收資本額約新台幣318,369,410元,已發行普通股約31,836,941股;2025-12-23 掛牌上市前公告之普通股約30,067,941股,另有現金增資股款繳納憑證1,769,000股。公司員工規模依113年度年報:2023年24人、2024年24人、2025-03-31為26人,屬小型高研發密度IC設計公司。主要股東依113年度年報截至2025-03-29:嘉澤端子工業股份有限公司持股4,732,059股、15.74%;高妙斌持股4,607,941股、15.33%,其配偶呂曉迪持股4,600,000股、15.30%;呂曉迪本人持股4,600,000股、15.30%;何朱顏持股7.44%;何碩頡持股7.36%;朱妍婗持股5.60%;朱佩璇持股5.59%;朱靖馥持股4.93%;祥碩科技股份有限公司持股1,200,000股、3.99%。嘉雨思為嘉澤端子工業股份有限公司之關聯企業,祥碩亦為策略投資人。

Business

嘉雨思主要從事高速訊號傳輸介面之數位類比晶片設計、開發、生產與銷售,核心產品為高速訊號中繼器 Re-Driver/Re-Timer、線性訊號等化晶片、資料中心光通訊IC等。公司採 IC 設計公司模式,主係進行電路設計、軟韌體整合與客製化功能開發,再委外進行晶圓製造、封裝與測試,無自有晶圓廠或量產廠房。依113年度年報,2023與2024年度營收結構均為高速通訊IC 100%;2024年營業收入151,727千元,年增38.76%,營業毛利99,435千元,稅前淨利22,858千元,EPS 0.76元;公司說明成長主因為市場需求回升、高階商用與Gaming PC需求增加,以及客戶轉單與E客戶新產品訂單全數由公司接單。主要產品與應用包含:USB4.0/DisplayPort 2.1主動連接器 Re-Driver、PCIe Gen5 Re-Driver與Mux/DeMux、PCIe Gen5 x16 Linear Re-Driver、USB4 v2/DP2.1 Linear Re-Driver with AUX switch、PCIe 6.0/CXL 3.0 Linear Re-Driver、PCIe 6.0/USB4 v2 Linear Optical Engine,以及面向 PCIe 7.0、Ethernet、400Gb/s光通訊的下一代高速傳輸晶片。終端應用涵蓋Gaming/Desktop、高階電競桌機、筆電、伺服器、資料中心、AI與HPC系統、4K/8K顯示主動線、USB4/DP、PCIe/CXL Cable。客戶名稱多於年報中匿名揭露:2024年前三大客戶為C客戶43.02%、E客戶40.14%、D客戶10.34%,合計逾九成,客戶集中度高;銷售地區依MoneyDJ資料,2025年1-9月台灣約97%、中國大陸約3%。

Outlook 2025–2028

2025至2028展望偏向高成長但伴隨客戶集中與技術迭代風險。成長動能方面,公司所處高速傳輸IC受惠AI伺服器、HPC、資料中心、雲端運算、PCIe/CXL世代升級、USB4/DP與高解析顯示主動線需求;年報引用產業趨勢指出AI推升高階邏輯製程與半導體需求,且全球邊緣運算硬體市場2023至2028年預估CAGR約15.3%,高速傳輸需求成為趨勢。公司已開發PCIe 6.0/CXL 3.0 Linear Re-Driver、PCIe 6.0/USB4 v2 Linear Optical Engine,並揭露PCIe 7.0、400Gb/s Optical Linear Re-Driver等方向,若能進入CPU/GPU主晶片生態系與主要平台認證,2025-2028可望由PC/主機板延伸至AI Scale-Up與Scale-Out互連、伺服器板級高速訊號補償與光互連。技術與商業模式方面,公司強調低功耗、低延遲、小體積、簡化系統設計,並將深化晶圓廠、封裝測試廠合作以確保產能與品質;自有相容性實驗室、Intel平台導入經驗、專利組合與嘉澤/祥碩資源是優勢。風險與挑戰包括:一、公司規模小、員工僅約26人,研發與客戶支援能量相較國際大廠有限;二、2024年C、D、E三大客戶合計約93.5%,單一客戶或新產品訂單變動將明顯影響營收;三、主要晶圓供應商高度集中,2024年A公司占進貨100%,若晶圓產能、良率或價格不利將影響交期與毛利;四、PCIe/USB/CXL標準快速迭代,若產品認證落後、功耗/訊號完整性表現不如競品,可能失去設計導入;五、競爭對手包含TI、群聯、祥碩、譜瑞、君曜、智微等,部分具更大資金、IP與客戶基礎;六、終端PC與消費性電子循環仍可能波動,雖AI/資料中心中長期趨勢正向,但實際放量時點與客戶採用情況仍需追蹤。

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.
