今年以來,模擬芯片板塊在二級市場表現相當搶眼,其中臻鐳科技(688270)股價翻倍。

作為半導體的重要分支,模擬芯片是處理模擬信號的集成電路,廣泛應用于聲音、光線、溫度等物理量的處理。今年,在汽車電子、泛能源、人工智能等相關新興產業的帶動下,本土模擬芯片廠商通過持續技術升級和產品結構升級,提升運營效率,取得了亮眼的成績。

證券時報記者統計發現,2025年第二季度,模擬芯片板塊盈利增速位居A股半導體細分行業之首。今年以來,模擬芯片板塊指數累計上漲近18%,板塊中的個股臻鐳科技股價翻倍,翱捷科技-U、敏芯股份、思瑞浦等股價上漲超過60%。

新興業務釋放動力

2022年成為模擬芯片行業景氣度拐點,從此前缺芯漲價轉向供給過剩,行業步入漫長的去庫存周期。但今年以來,模擬芯片板塊盈利增速顯著提升,特種領域、工業市場、汽車電子等成為業績增長的重要新興助力。

Wind數據顯示,今年上半年A股(申萬)半導體行業營業收入實現3212億元,歸母凈利潤近245億元,同比增長約三成。其中,第二季度半導體行業盈利環比增長近六成,尤其是模擬芯片行業上市公司歸母凈利潤環比增長約4倍,增速超過其他細分行業;34家模擬芯片上市公司中,約六成上市公司第二季度盈利同比上漲,不少個股“絕地反擊”,同比大幅扭虧。

臻鐳科技今年上半年歸母凈利潤增速居首,同比增長10倍,其次是思瑞浦和芯動聯科。第二季度中,敏芯股份盈利環比增速居前,達到6.84倍;晶豐明源、思瑞浦等實現2倍以上。

具體來看,臻鐳科技今年上半年歸母凈利潤實現約6232萬元,同比增長約10倍,二季度“牛散”屠黎明、葛衛東精準“埋伏”,位居前十大股東。據披露,公司產品主要應用于衛星互聯網產業鏈,受益于下游行業回暖、需求持續向好的趨勢,在手訂單和在手項目同比大幅增長。

思瑞浦今年上半年歸母凈利潤近6569萬元,同比大幅扭虧,電源產品、隔離、ADC、運放等在工業市場出貨量明顯提升。公司高管介紹,工業市場作為公司最大業務板塊,上半年收入同比增長約50%,二季度環比繼續保持強勁增長;受下游備貨及國產替代持續推進,新能源(光伏、儲能)、電力電網、電源模塊、測試測量、家用電器等領域表現突出,汽車市場也實現穩健增長,并布局AI服務器。

晶豐明源今年上半年實現歸母凈利潤1576萬元,同比大幅扭虧。據公司高管介紹,在新一代顯卡應用出貨帶動下,高性能計算電源芯片業務實現快速增長,該部分業務收入同比上升約四成,汽車電子業務繼續實現突破,推出了超高集成度的ALL-in-One智能車規級MCU,空調出風口產品實現銷量超百萬顆,熱管理及座椅通風也都有產品進入量產。

產品結構升級

據統計,今年上半年模擬芯片行業銷售毛利率中位數從今年一季度34.72%,提升到第二季度35.05%。個股中,傳感器廠商芯動聯科二季度毛利率最高接近88%,公司已覆蓋的終端客戶包括高端工業領域、測繪測量、石油勘探、商業航天、智能駕駛等領域;臻鐳科技也接近83%,賽微微電、圣邦股份等銷售毛利率水平也超過50%。綜合來看,上述公司主要受益于消費電子、汽車電子、端側智能裝備等需求放量,高毛利產品出貨增加。

傳感器廠商敏芯股份今年上半年歸母凈利潤大幅扭虧,實現2519萬元,產品綜合毛利率31.64%,同比增加10.21個百分點,主要得益于MEMS聲學傳感器在消費電子與汽車電子領域的廣泛應用,以及MEMS壓力傳感器在電子煙、醫療設備和工業控制市場的持續拓展。

從產品劃分來看,敏芯股份高毛利的壓力產品線已超越聲學產品線,成為占公司營業收入比重最高的傳感器產品;同時,慣性傳感器產品收入比重也在快速提升,整體拉升了公司的產品毛利率。

另外,美芯晟來自AI端側及機器人領域的應用持續增長,通過產品結構的優化與供應鏈的持續整合,提升了毛利率,運營效率及經營管理效率得到改善,今年上半年實現歸母凈利潤500.68萬元,也同比扭虧。

艾為電子今年上半年雖然營業收入下降,但是歸母凈利潤同比增長七成實現1.56億元。據介紹,下游消費電子客戶需求和去年同期存在錯位,但是隨著新產品持續放量及工業互聯、汽車領域的持續開拓以及產品迭代更新,公司綜合毛利率較上年同期上升8.03個百分點至36.12%。

艾為電子高管在2025年半年度業績說明會上表示,公司下半年將繼續加快高性能數模混合、電源管理、信號鏈芯片新料號的推出,積極布局端側AI應用領域。

除了產品結構升級外,芯片采購成本下降成為毛利率修復的因素之一。

匯頂科技今年上半年營業收入同比微降,而歸母凈利潤4.31億元,同比增長近36%。據介紹,受下游客戶備貨節奏影響,公司出貨量不及去年同期水平,但在芯片采購成本下降、新產品量產及現有產品迭代等因素帶動下,毛利率提升至43.3%。

存貨周轉提速

在基本面修復背景下,模擬芯片行業存貨周轉進一步提速,今年第二季度中位數近177天,已經超過2022年同期存貨周轉水平;近六成上市公司存貨周轉天數壓縮。個股中,希荻微、思瑞浦、臻鐳科技等今年上半年存貨周轉天數顯著壓縮,而鉅泉科技、卓勝微和賽微微電等存貨周轉天數延長。

據披露,鉅泉科技去年公司主營業務智能電表芯片營業收入毛利率降低7.15個百分點,主要由于國網、南網招標量增加,導致銷量上升,但因售價降低,導致收入下降,成本增加,毛利率降低。今年上半年歸母凈利潤同比下降約三成,綜合毛利率41.13%,同比有所下降。

不過,鉅泉科技第二季度盈利環比增長約2倍。據介紹,公司布局BMS芯片新業務領域已實現市場突破并獲得相應訂單,為公司培育新的業績增長點;公司最新已在清潔電器、電動工具等消費電子領域實現批量訂單發貨,同時積極拓展工業自動化及車規級場景應用,如鋰電池管理、戶外電源等。

射頻芯片龍頭卓勝微今年上半年營業收入17.04億元,同比下降25.42%,歸母凈利潤-1.47億元,同比轉虧,公司毛利率從去年上半年42.11%下滑至28.75%。

公司高管在接受調研時指出,隨著芯卓產線量產,其中設備投入最大的12英寸射頻開關、低噪聲放大器工藝線在去年年中進行了大規模量產轉固。去年下半年,產能爬坡初期產能利用率不足,導致單片實際成本異常。該部分成本較高的晶圓經后道加工成產品,在2025年上半年銷售給客戶后,對公司的毛利率和盈利能力表現產生了較大擾動。同時,受到市場競爭與芯卓折舊金額增加的多重影響,公司毛利率下滑。

隨著芯卓產品持續上量,產線運轉效率提升,降本拐點等跡象陸續出現,卓勝微高管預計,公司后期相關產品毛利將企穩回升。
