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 宇瞻 do? Company profile

半導體業；記憶體模組與快閃記憶體儲存解決方案上市

Overview

8271 對應宇瞻科技股份有限公司，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 1997/04/16，掛牌上市日期為 2010/12/29，總部位於新北市土城區忠承路32號1樓。依 2026/06/17 可查之公開股市基本資料，董事長為陳益世，總經理為張家騉，發言人為賴孜玟，股務代理為凱基證券，簽證會計師為安侯建業聯合會計師事務所；實收資本額約新台幣 12.96 億元，已發行普通股約 129,614,266 股。員工規模方面，2024 年永續報告書揭露 2024 年底全球員工 598 人，生產線直接員工約 27%、間接員工約 73%；2024 年報台灣含子公司口徑為 534 人，2025/02/28 為 531 人。股權方面，年報揭露董事會/法人董事與宏碁等淵源，鉅亨網最新頁面列前十大持股合計約 17.78%、董監持股約 17.44%至17.85%區間；但個別前十大股東與最新持股名單需以公開資訊觀測站股東會年報與集保資料為準。公司原為宏碁體系記憶體模組事業之一，後發展為 Apacer 品牌，長期聚焦工業級 SSD、DRAM 模組、記憶卡、隨身碟與嵌入式儲存。

Business

宇瞻的主要業務為 DRAM 記憶體模組與 NAND Flash 快閃記憶體產品之設計、製造、測試、銷售與加值韌體/軟體解決方案。依 2024 年報，2024 年營收新台幣 78.37159 億元，其中快閃記憶體 47.76364 億元、占 60.95%；記憶體模組 29.49576 億元、占 37.64%；其他 1.11219 億元、占 1.41%。產品線包括桌機/筆電/超頻 DRAM 模組、IPC/伺服器/印表機/網通/路由器專用記憶體、工業 USB、PCIe/SATA/ATA Disk Module、BGA SSD、2.5 吋/U.2/E1.S/E3.S/M.2/mSATA/CFast/SD/microSD、企業級 SATA/PCIe SSD、寬溫與抗硫化模組、DDR5 UDIMM/SODIMM/ECC/RDIMM/CUDIMM、全無鉛 DDR5、CorePower 斷電保護 SSD、CoreSnapshot/CoreRescue 備份還原技術、WORM 一寫多讀資料保護，以及智慧 IoT、AI+AOI 光學檢測與自動化解決方案。商業模式以自有品牌 Apacer、工業/嵌入式客戶客製化設計、通路銷售、B2B design-in、消費與電競通路並行；工控產品重視長生命週期、BOM 穩定、寬溫、抗震、資料完整性、斷電保護、資安與韌體加值。終端應用涵蓋工業電腦、工廠自動化、IoT/AIoT、5G 與網通、伺服器/雲端/資料中心、AI 伺服器與邊緣運算、交通/車載、醫療、國防、POS、監控、教育、智慧零售、無人機、個人電腦、筆電、遊戲與電競、相機與消費性儲存。2024 年報揭露單一客戶並無占銷貨 10% 以上，顯示下游客戶相對分散。

Outlook 2025–2028

2025 至 2028 年展望主軸為記憶體循環、AI/邊緣運算帶動高容量高可靠儲存、DDR5 世代轉換、工控與企業級 SSD 滲透、以及 ESG 無鉛產品。2024 年報列 2025 策略為「精煉工控」與「擴大通路」，工控重點應用包括 IoT、伺服器、網通與國防固態化；消費端則強化特定區域通路與高階儲存產品。研發規劃包括 PCIe Gen4 工業 SSD、PCIe Gen5 消費 SSD、SSD 軟硬韌體架構、工業用 SATA/PCIe/USB 嵌入式儲存、DDR5 新規格、工業光學檢測與智慧 IoT 平台，2025 年預估研發投入約新台幣 1.60679 億元。2025 Computex 資訊顯示，公司推出面向 AI 伺服器、雲端、資料中心、邊緣運算與智慧製造的 PCIe Gen5 企業級 SSD、BiCS8 相關 SSD、CoreVolt 2 電壓穩定、CoreEnergy 能耗調節、全無鉛 SSD/DDR5，以及 DDR5 CUDIMM/高頻電競記憶體。2026 年公開新聞顯示，記憶體供需緊俏與價格上漲使宇瞻 2025 年營收達 111.24 億元、年增 41.93%、EPS 6.70 元，2026 年第 1 季營收 70.42 億元、EPS 14.54 元並創高；2026 年 3 至 5 月營收年增幅仍高，反映短期受惠於 DRAM/NAND 漲價與客戶拉貨。中長期成長動能包括 AI 伺服器與企業級 SSD 容量升級、CSP/伺服器 DDR5 與高容量 RDIMM、工控/邊緣 AI 對高可靠儲存需求、Raspberry Pi 生態導入智慧教育/零售/無人機/智慧工廠、歐美高階消費通路、以及無鉛與低功耗產品因應環保法規。主要風險包括 DRAM/NAND 價格劇烈波動、上游原廠供給與配額、庫存水位與跌價風險、客戶轉嫁成本能力、消費性電子需求疲弱、AI 伺服器需求不如預期、同業價格競爭、匯率波動、地緣政治/關稅、原物料如 IC/PCB/玻纖布/金屬價格上漲，以及工控 design-in 週期長造成營收認列延後。2027 至 2028 年未見公司明確量化財測，以上為依公司策略、年報產業趨勢與公開新聞推估。

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.
