MaxLinear的AI利润是真的,也是借来的:基础设施收入增210%,流动性契约下限降至6000万美元

第三季度,MaxLinear实现多年来首次按美国通用会计准则(GAAP)计算的营业利润,AI光通信基础设施业务增长210%;但当晚披露的文件显示,流动性契约有所放宽,经营活动现金仍在净流出。放量是真的;这个季度的放量,是贷款方买的单。

MaxLinear联合创始人、董事长兼首席执行官基肖尔·森德里普(Kishore Seendripu)。第三季度财报发布前六天,公司修订信贷安排,新增7000万美元承诺额度,并将流动性契约下限降至6000万美元。

MaxLinear−17.40% — MaxLinear, down 17.40 percent today以季度业绩兑现了AI转型的承诺,却在同一份文件里悄悄放宽了背后的贷款条款。当季营收2.181亿美元,同比增长72%1。基础设施业务的收入如今建立在AI数据中心光芯片之上,当季增长210%1。公司实现至少三年来首次GAAP口径营业利润,营业利润率达13.9%,而去年同期尚为亏损12。

10月16日,也就是财报发布前六天,公司签署修订协议:新增7000万美元承诺额度,将有担保信贷安排扩大至2亿美元1。同一批文件还将流动性契约下限从8000万美元下调至6000万美元1。增长是真的。这个季度,增长也是借来的。

三周前,我们曾报道:在首席执行官套现5000万美元股票的几周后,这家公司对日渐萎缩的线缆业务降价3。如今,对那篇文章留下的疑问,AI业务给出了答案。投资者并不买账:尽管营收、利润和业绩指引均超预期,MaxLinear股价仍在10月22日盘后下跌——此前一年,该股已累计上涨约三倍45。

光芯片放量已成公司主业

第一跳是实打实的。AI集群通过光纤在服务器之间传输数据,每条800G和1.6T链路都需要一颗数字信号处理器(DSP)来驱动和恢复信号1。MaxLinear的Keystone PAM4 DSP本季度实现批量出货,Rushmore和Annapurna系列则将产品线延伸至1.6T的光、电两类器件1。12月当季2.4亿至2.6亿美元的营收指引表明,放量仍在继续1。

利润先行,现金滞后

下一跳——从营收到现金——尚未落地。按GAAP口径,MaxLinear本季度实现利润2890万美元1。但经营活动仍消耗了1360万美元现金,原因在于应收账款、存货和预付供应商款项的增长快于客户回款1。预付款项及其他流动资产自去年12月以来已增长逾一倍7。截至9月30日,公司持有现金8110万美元,循环信贷已提取4000万美元7。

盈利到来的当季,经营现金流再度转负

这一点在流动性契约上体现得最清楚。该契约以非受限现金加未动用承诺额度为指标,每个季度末测试一次;贷款方今年4月把契约下限设在8000万美元,10月又上调承诺额度、将下限降至6000万美元,两步操作都扩大了放量在贷款触发违约前可消耗的现金空间7。文件载明,新增额度用于“营运资金及一般公司用途”,富国银行+0.73% — 富国银行, up 0.73 percent today担任抵押代理行1。

贷款方不愿承担的风险,落在了股东身上

申报文件点名了由谁来承担下行风险。增长集中在少数超大规模客户手中,公司已把这些客户AI资本开支的可持续性列为风险1。慧荣科技−17.27% — 慧荣科技, down 17.27 percent today就MaxLinear 2023年放弃的那桩合并交易在新加坡提起的仲裁仍在进行,索偿包括终止费及损害赔偿;相关潜在付款,也列在公司自己披露的现金需求清单上7。贷款方手握抵押品,还有费用可收。这些被点名的风险,最终都落在股东头上。

利润表在本季度迎来拐点,现金流量表还没有。今年以来,看多这只股票的逻辑一直押在盈利与现金流的持久拐点上,一位分析师在财报发布前撰文,称这一拐点“尚未得到证明”6。只有当经营现金流与利润同步转正,这场困境反转才不再是“借来的”;而那份修订协议表明,公司与贷款方都为这段等待早有安排。
