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 新盛力 do? Company profile

電腦及週邊設備業；高功率鋰離子電池模組、BMS、BBU/UPS/儲能與輕型電動交通工具應用櫃買中心上櫃

Overview

4931 為新盛力科技股份有限公司，屬營運公司普通股，於櫃買中心上櫃。公司成立於 2004-07-26，總部位於高雄市前鎮區西十五街1號，統一編號 70848850，董事長為張中秋，公開股市資料列總經理亦為張中秋，發言人為范貴鈞。公司於 2017-04-27 登錄興櫃、2019-09-17 上櫃。公司官網投資人專區揭露實收資本額為新台幣 655,657,610 元；104 人力銀行資料列員工約 400 人。公司前身可追溯至 Sony 在台鋰離子電池模組生產基地，2004 年由原經營團隊與投資人正式成立新盛力，後續逐步由筆電電池模組轉向非 IT 高功率電池模組。公司截至 2026-03-29 官網揭露十大股東為：晶采光電科技股份有限公司代表人蘇漢傑 3,200,000 股、4.88%；李國豐 2,212,000 股、3.37%；張中秋 1,424,385 股、2.17%；龍翰興業股份有限公司代表人楊維顏 1,000,000 股、1.53%；范貴鈞 816,766 股、1.25%；楊陳秋華 643,239 股、0.98%；鄭棍方 630,000 股、0.96%；傅英嘉 570,000 股、0.87%；陳思翰 529,000 股、0.81%；李佳龍 500,000 股、0.76%。115 年度年報資料顯示 2025 年合併營收 2,451,377 千元、稅後淨利 203,562 千元、EPS 3.13 元；2026 年 1 至 5 月公司官網月營收分別為 289,976、218,293、283,109、302,908、415,943 千元。

Business

新盛力核心業務為鋰離子電池模組之研發、設計、製造、組裝與銷售，搭配自有設計與生產的電池管理系統 BMS、客製化機構設計與安規驗證能力，主要產品應用於三大領域：人工智慧算力中心與伺服器用鋰離子電池備援系統模組（BBU/UPS/BESS）、電動手工具用鋰離子電池模組、電動輕型交通工具用鋰離子電池模組；其他應用包括筆記型電腦、醫療、餐飲儲能、工業、雲端機房、家用與車載能源儲存。114 年度年報彙整資料列產品組合為鋰離子電池模組 2,441,954 千元、約 100%，其他 9,423 千元、約 0%；公司致股東報告指出 2025 年產品仍以電源備援系統、電動手工具及電動輕型交通工具三大領域之鋰離子電池模組為主，銷售地區主要為美國、歐洲等市場，直接與間接外銷約占營收 99%。商業模式以高功率、多串併、客製化電池模組 ODM/OEM 為主，價值不在電芯製造，而在電芯選型、BMS、韌體、散熱與安全設計、安規認證、量產組裝與品質管控。歷史報導提及儲能終端大客戶曾包括 HPE，電動工具大客戶為美國上市專業級電動工具 S 牌，輕型電動車客戶包括日本 DENSO 與榮輪；另早期筆電電池模組曾通過 HP、華碩、廣達、仁寶等國際大廠認證。上述客戶多屬歷史或市場報導資訊，公司近年未完整公開最新客戶名單。

Outlook 2025–2028

2025 年已驗證公司由電動工具、輕型電動車轉向資料中心備援電源的成長軌跡：2025 年營收 24.51 億元、年增約 23%，稅後淨利年增約 26%，主要受惠 AI 算力中心電源備援系統需求提升。2026 年主要成長動能來自 AI 伺服器、CSP 資料中心、HVDC 高壓直流架構與 BBU/UPS 滲透率提升；MoneyDJ 報導指出高壓 BBU 於 2025Q3 已有試樣單，放量時間估落在 2026 年下半年，法人預期 2026 年營收與毛利率有望續創高。公司 2025 年研發支出約占營收 4%，開發項目包括 AI 算力中心電源備援系統、伺服器機架電源備援系統、伺服器主板電源備援系統、次世代高功率密度電動手工具電池模組與無人機電池模組；公司亦規劃導入新型態鋰離子電池組裝、提升自動化製程、因應客戶異地生產要求。2027 至 2028 年展望屬推估：若 AI 伺服器功耗持續提高、GB300 以後平台擴大 BBU 配置、CSP 資料中心由集中式 UPS 轉向機架或伺服器內建 BBU，則高壓、高容量、高可靠度電池模組需求有機會延續；公司可望透過既有客戶產品線垂直深耕與新客戶水平擴散，提高 BBU/UPS 與儲能占比，同時維持電動工具、輕型電動交通工具作為基礎營收。主要風險包括：電芯與關鍵零組件供應集中於日韓與中國大廠、電芯價格與鋰料價格波動、客戶認證進度與訂單集中度、BBU 規格轉換與高壓安全法規、CSP 或伺服器平台導入時程不確定、匯率波動、擴產與自動化良率、同業 AES-KY、順達、新普及其他 BBU 新進者競爭加劇。
