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

康聯訊主要經營光纖網路局端、用戶端設備及網管交換器之研發、製造及買賣，定位為利基型光纖網通設備供應商，產品涵蓋FTTX光纖到府架構下從接取層、分配層至用戶端的關鍵設備。113年度營收結構為光纖交換器200,874千元、占68.23%，光纖轉換器50,611千元、占17.19%，語音閘道器9,010千元、占3.06%，其他33,930千元、占11.52%，合計294,425千元；112年度營收為370,386千元，113年度年減20.51%。產品用途包含光纖/銅線交換器、光纖轉換器、多媒體家用閘道器與Wi-Fi Mesh路由器。商業模式以自主產品研發、自有品牌行銷、外銷與區域在地化支援為主，生產主係委外生產及組裝，公司本身以產品設計、研發、供應鏈管理、銷售與客戶服務為核心。113年度銷售地區為亞洲206,672千元、占70.20%，歐洲74,006千元、占25.14%，內銷11,283千元、占3.83%，美洲1,306千元、占0.44%，其他1,158千元、占0.39%。年報揭露主要下游客戶以匿名A公司為主，113年度銷貨155,223千元、占52.72%；直接客戶群包含歐洲及亞洲大型電信營運商，亦透過系統整合商與代理商切入海外電信、寬頻、光纖到府、智慧建築、智慧交通、工業自動化與企業網路應用。

Outlook 2025–2028

2025至2028年展望以營運改善與產品升級為主。成長動能包含全球FTTH/FTTB、10G接取網路、Wi-Fi 6/6E/7、2.5G/Multi-G乙太網路、802.3bt 60W/90W PoE、智慧建築、智慧交通、工業自動化、邊緣AI與AI基礎建設對高頻寬低延遲網通設備的需求提升。公司年報短期產品策略為從FTTX延伸至10G新一代產品，Wi-Fi產品向家庭應用場域延伸，交換機產品線由營運商接取端往10G至100G接取網路擴展，並規劃NetConf API以滿足營運商與ICT自動化整合需求；長期則投入AI基礎建設所需功能，發展10G至100G寬頻線路建置與90W PoE強固型產品線。2025年新聞報導指出，公司規劃推出4款10Gbps media converter、新版本10Gbps CPE Switch，Multi-G Ethernet Gateway Router已進行首批量產出貨日本當地SI，PoE產品規劃2025年下半年至2026年上半年陸續推出2款工規與1款商用產品。生產與供應鏈方面，公司2025產銷策略為加強供應商整合與新廠商開發、縮短交期、降低物料成本，並備妥其他地區代工廠以因應地緣政治與貿易變局。主要風險包含歐洲市場需求下降、客戶庫存調整、低價競爭、產品價格持續下滑、新產品導入未必即刻形成實質營收、股本與規模較小導致研發與品牌推廣資源受限、匯率與關稅/貿易政策不確定性；年報亦指出公司規劃增資籌資以改善財務結構與支應產品研發及市場拓展。

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.
