US optical component stocks are rising, yet Zhongji Innolight fell 9.19% in one day, and some say this is AI capital expenditure peaking. To test this claim, which document is fastest? Are the four cloud providers' capital expenditure guidance from late January to early February 2027 enough?

美股光器件在涨,中际旭创一天却跌9.19%,有人说这是AI资本开支见顶。要验这个说法,哪份文件最快?2027年1月底到2月初四家云厂的资本开支指引够不够?

Answer translation · machine-translated (original 中文)

It is not a capex peak. The fastest document is already sitting on the SEC: the 8-K Coherent filed on November 4, Exhibit 99.1, and the first page says it all.

It is the company among US optical components makers that is closest to A-share optical modules, and it reported the September quarter. A single release packs in four markers: the current quarter, the December quarter guidance, the full fiscal year, and the 2028 step-up.

Revenue 23.70 yi US dollars, quarter-on-quarter +15.9%, year-on-year +49.9%; GAAP gross margin 39.1%, last quarter 38.5%, same period last year 36.6%. December quarter guidance 25.5 to 27.5 yi, divided by the midpoint gives quarter-on-quarter +11.8% (the company only gives endpoints; this quarter-on-quarter figure is my calculation). non-GAAP gross margin guidance 40% to 42%, actual this quarter 40.6%, the upper half of the guidance is higher than actual. Full-year pro forma "exceeding 60%", and in fiscal 2028 it wants to reach its first 4 yi quarter.

A company having orders cut would not simultaneously raise its gross margin guidance, nor would it give you a 2028 step-up.

Put the three side by side, and the next-quarter slope is layered

Lumentum (light sources, pump lasers, optical switches): current quarter 12.626 yi, quarter-on-quarter +25.5%, next quarter 15.75 to 16.25 yi, quarter-on-quarter +24.7% to +28.7%, accelerating.

Coherent (modules plus chips mixed): next quarter +7.6% to +16.0%, flat at a high level.

Fabrinet (pure assembly contract manufacturing): current quarter 14.745 yi, quarter-on-quarter +12.1%, next quarter 16 to 16.5 yi, quarter-on-quarter +8.5% to +11.9%, decelerating.

The closer to assembly, the softer; the closer to light sources, the harder. This is not demand peaking, it is orders changing position within the chain: the 1.6T and co-packaged optics generational shift moves the assembly end first, then volume moves toward the light source end.

That A-share candlestick

Zhongji Innolight is precisely the purest name at the assembly layer. If it were only a layer problem, it should move in the same direction as Fabrinet — Fabrinet rose 11.66% this week, while it fell 9.19%.

The tape gave the answer. That day Zhongji Innolight traded 239.7 yi, Dongshan Precision 123.0 yi down 10.00%, Wus, Shengyi, and Jingwang all fell 9.3% to 9.6%, PCB and copper-clad laminate fell in a string; at the same moment Shanghai Film rose 10.00%, Simei Media rose 9.96%. The money did not leave the market, it moved from AI hardware into film and media. Such a large sell volume paired with media stocks on the other side hitting limit-up is positions moving, not demand being recalculated.

Why it sold off like that that day, I have no evidence, and I will not attribute it. But a capex peak cannot explain it — in the same week Coherent, Fabrinet, and Lumentum rose; AMD data center year-on-year +97%, Lam next quarter only +4.6%, Amkor flat — compute power and optics are accelerating, equipment and packaging are not.

The capex guidance from those four companies at the end of January 2027, is it enough

Not enough. Not too late, but the wrong position.

It is an aggregate, and moreover an aggregate at the very upstream of the chain. "Purchases of property and equipment" contains land, buildings, power, non-AI servers. The same number can go up while cutting orders for a certain generation of modules — the timing of the generational shift matters more than the aggregate. What fell in A-shares this time is the PCB and copper-clad laminate layer, which is invisible in the total.

It is also one quarter later than the optical components quarterly reports: cloud capex guidance only arrives at the end of January, while these three companies will have finished reporting the December quarter in early February.

The leading line is not in capex. Lumentum's release says: won a second NPO/CPO project, "backed by purchase commitments exceeding $5 billion", the customer is locking capacity with money, one quarter earlier than cloud capex. Those four are final rulings, not early warnings.

The strongest counterargument: you are using questions set by the person being tested to prove he did not cheat. The three companies' November accelerating guidance only shows no orders were cut before December, it does not show no orders will be cut in January. Module order cycles are one to two quarters, cloud budget years switch in January — if the full-year budget really were cut in January, module makers would not know in January and would only revise down in February. January is exactly the invisible month; this claim cannot be falsified now, only by February's documents.

I accept this, but it has a testable point: real order cuts land first on purchase commitments, not on guidance. Once the customer's capacity-locking money is not renewed, the "exceeding $5 billion" tier in the next quarter's release will shrink or no longer appear.

What would count as me being wrong: Fabrinet's early-February March quarter guidance turning negative quarter-on-quarter — the assembly layer turning negative first means I am wrong. The second is that sentence about purchase commitments disappearing from Lumentum's release.

不是资本开支见顶。最快的文件已经躺在 SEC 上了:Coherent 11月4日交的 8-K,附件 99.1,第一页就写完了。

它是美股光器件里最贴着 A 股光模块的一家公司,报的还是 9 月季。一份稿子里压着四个刻度:本季、12 月季指引、整财年、2028 年的台阶。

收入 23.70 亿美元,环比 +15.9%,同比 +49.9%;GAAP 毛利率 39.1%,上季 38.5%,去年同期 36.6%。12 月季指引 25.5 到 27.5 亿,按中值除出来环比 +11.8%(公司只给端点,这个环比我算的)。non-GAAP 毛利率指引 40% 到 42%,本季实际 40.6%,指引上半段比实际还高。全年备考"超过 60%",2028 财年要做到第一个 40 亿季度。

被砍单的公司不会同时抬高毛利率指引,也不会给你 2028 年的台阶。

三家摆一起,下季斜率是分层的

Lumentum(光源、泵浦激光器、光开关):本季 12.626 亿,环比 +25.5%,下季 15.75 到 16.25 亿,环比 +24.7% 到 +28.7%,加速。

Coherent(模块加芯片混装):下季 +7.6% 到 +16.0%,高位平着走。

Fabrinet(纯组装代工):本季 14.745 亿,环比 +12.1%,下季 16 到 16.5 亿,环比 +8.5% 到 +11.9%,减速。

越靠近组装越软,越靠近光源越硬。这不是需求见顶,是订单在链内换位置:1.6T 和光电共封装的换代先动组装端,再往光源端走量。

A 股那根 K 线

中际旭创正是组装这一层最纯的标的。若只是层的问题,它该和 Fabrinet 同向——Fabrinet 这周涨 11.66%,它跌 9.19%。

盘面给了答案。那天中际旭创成交 239.7 亿,东山精密 123.0 亿跌 10.00%,沪电、生益、景旺齐跌 9.3% 到 9.6%,PCB 和覆铜板成串下跌;同一时刻上海电影涨 10.00%、思美传媒涨 9.96%。钱没离开市场,从 AI 硬件搬进了影视传媒。这么大的出货量配上对面涨停的传媒股,是持仓在动,不是重算需求。

那天为什么这么卖,我没有证据,也不给归因。但资本开支见顶解释不了它——同周 Coherent、Fabrinet、Lumentum 是涨的;AMD 数据中心同比 +97%,Lam 下季只 +4.6%,Amkor 走平——算力和光在加速,设备和封装没有。

2027 年 1 月底那四家的资本开支指引,够不够

不够。不是太晚,是位置不对。

它是总量,而且还是链条最上游的总量。"购置不动产及设备"装着土地、厂房、电力、非 AI 服务器。同一个数可以一边往上走,一边把某一代模块的订单砍掉——换代时点比总量重要。这次 A 股跌的是 PCB 和覆铜板这一层,总数里看不见。

它比光器件季报还晚一季:1 月底才拿到云厂指引,而这三家 2 月初就交完 12 月季了。

领先的那一行不在 capex 里。Lumentum 稿里写着:第二个 NPO/CPO 项目中标,"backed by purchase commitments exceeding $5 billion",客户拿钱锁产能,比云厂 capex 早一个季度。那四份是终审,不是预警。

反方最强的一条:你是在拿被考核的人自己出的题,去证明他没作弊。三家 11 月的加速指引只说明 12 月前不砍单,说明不了 1 月不砍。模块订单周期一到两个季度,云厂预算年度 1 月切换——真要 1 月把全年预算砍了,模块厂 1 月不知道,2 月才下调。1 月恰好是看不见的那个月,这话现在否证不了,只能被 2 月的文件否证。

这条我认,但它有个可检验的地方:真砍单先落在采购承诺上,不落在指引上。客户锁量的钱一不续,下季稿里"exceeding $5 billion"这一档就会变小或不再出现。

什么情况算我看错:Fabrinet 2 月初给的 3 月季指引环比转负——组装层先转负就是我看错。第二个是 Lumentum 稿里那句采购承诺消失。

所以,这 9.19% 卖的不是需求,是一个还没到的月份。要验它,最快的不是云厂的资本开支指引,是供应商账上的预付款和订单口径——前者是"打算花多少",后者是"已经花了多少"。

## 先把这一季拆开:坏的不是毛利线

三季报 10 月 30 日就出了,比这根阴线早三个交易日。单季拆出来:收入 277.69 亿,环比 +24.6%,同比 +171.83%;毛利率 46.61%,二季度 46.42%,还升了 0.19 个百分点。

怪的是利润。单季归母 85.87 亿,环比只增 8.5%;单季扣非归母 90.18 亿,比归母还高 4.3 亿。扣非高于归母只有一个原因:非经常性损益是负的。

公司在 10 月 29 日的电话会上把这两笔讲明白了。一笔是持有的上游核心供应商二级市场股票回调,公允价值变动损失税前约 6.2 亿;一笔是 7 月底 H 股发行后,港币募集资金在三季度汇率波动里形成汇兑损失,税前约 3.9 亿。合计 10.1 亿,全在毛利线以下,一张订单都不涉及。

> "若将上述特殊事项还原,经营性利润的环比表现与收入的环比增长基本匹配。"——2026-009 号记录表

算一遍也对得上:单季营业利润 106.12 亿,加回 10.1 亿是 116.22 亿,比二季度的 96.96 亿增 19.9%。同期毛利环比增 25.99 亿,费用环比只多 4.59 亿——毛利没有被吃掉,吃掉利润的是毛利线以下那两笔。

所以这张季报:收入在加速,毛利率在抬,经营利润跟着收入走,报表利润被两笔非经营性损失按住。市场若在重算需求,对象错了;若在重算估值,那和"资本开支见顶"是两件事。

```

## 同一张标签下,毛利率是分叉的

八家公司三季报的单季数摊开,分叉比总量有用。

| 公司 | Q3单季收入(亿) | 环比 | 单季毛利率(Q2→Q3) |
|---|---|---|---|
| 中际旭创 | 277.69 | +24.6% | 46.42→46.61 |
| 新易盛 | 109.40 | -13.0% | 47.96→46.27 |
| 天孚通信 | 19.23 | +28.4% | 64.66→65.05 |
| 太辰光 | 10.07 | +52.6% | 33.27→26.94 |
| 沪电股份 | 95.36 | +27.6% | 41.28→44.02 |
| 生益科技 | 141.82 | +30.3% | 32.63→41.63 |

新易盛单季收入环比 -13.0%;太辰光收入 +52.6%,毛利率却掉了 6.32 个百分点。只看这两家,"见顶"或者"杀价"都成立。

但同一个季度,旭创 +24.6%、天孚 +28.4%、光迅 +32.2%、沪电 +27.6%、生益 +30.3%、胜宏 +11.8%。八家里七家收入在环比增,一家在减。这不叫总量见顶,叫订单在客户之间换位置。

更关键的是最上游。11 月 6 日跌得最狠的是 PCB 和覆铜板,可它们的三季报毛利率是全链最陡的:生益单季 41.63%,环比 +9.00 个百分点;沪电 44.02%,+2.75;胜宏 34.17%,+2.06。

需求真见顶,最先裂的应该是离订单最远、扩产最凶的这一层。它没有裂,反而扩得最猛。

用毛利率分叉去解释一根 K 线,比用"资本开支见顶"解释得通:跌的是持仓和估值,不是毛利。

## 传导链:价值量在换代里换位置

这条链四层:云厂预算 → 光模块的 800G/1.6T 订单 → 光引擎、CW 光源、DSP → PCB 和覆铜板。每层卡的不是同一个东西。

卡点在中间。公司在 10 月 29 日说,DSP"供给偏紧张""价格较为坚挺";CW 光源要等供应商产能释放;1.6T 的良率还在爬。这三样决定 2027 年谁能交货,不决定云厂花多少钱。

议价权看毛利率分布就清楚:天孚 65.05%,旭创 46.61%,沪电 44.02%,生益 41.63%,光迅 25.51%。越靠近光引擎和光源越硬,纯组装和传统光通信最软。旭创站在中间偏上,靠的不是组装,是硅光比例——公司说硅光"毛利率优于传统方案",占比提升能优化 BOM 结构。

链条上还有一个比资本开支早得多的信号,藏在资产负债表里:三季度末存货 238.78 亿,比年初的 126.81 亿增 88.30%;预付款项 15.67 亿,比年初的 1.34 亿增 1068.43%。三季报给的原因都是同一句——在手订单增加,提前向上游锁料。

这是用钱投的票,比管理层说什么都硬。它也可能变成积压,下一季要看收入能不能消化掉;但在三季报这个时点,它是备货,不是积压。

落到报表上,各走各的科目:产品结构变化走营业收入和营业成本;锁料走存货和预付款项;汇率走财务费用;持股的公允价值走公允价值变动损益。四件事混在一起看,就会把汇兑损失当成需求下滑。

## 那四份资本开支指引,为什么不够

不够,但不是因为太晚,是因为三件事。

第一,它是总量。"购置不动产及设备"里装着土地、厂房、电力、非 AI 服务器。同一个总数可以一边往上,一边把某一代模块的订单砍掉。2027 年真正的变量是 800G 和 1.6T 的比例,不是四家公司加起来的那个数。

第二,它拆不到代际。四份 10-K 的分部和地域披露里没有"光模块"这一行,更没有"1.6T"。要验的那个东西,在那个科目里根本不存在。

第三,时间上它给不了提前量。按往年节奏,四家云厂(微软、亚马逊、谷歌、Meta)的四季报在 1 月底到 2 月初,Coherent、Fabrinet、Lumentum 的 12 月季也在 2 月初。两边几乎同时,资本开支不早于器件季报。

那最快的文件是什么,要分两个问题。问"这个季度有没有砍单",最快的是 Coherent 11 月 4 日那份 8-K,它报的就是 9 月季,还给了 12 月季和 2028 年的台阶。

问"2027 有没有订单",最快的不是任何一份美股文件,是旭创自己 11 月 3 日的记录表——它把"订单"和"指引"分开了:

> "公司所称订单是客户给出的确定性 PO,与需求指引(guidance)有严格区别。"——2026-010 号记录表

这句话比任何资本开支数字都值钱。资本开支是董事会打算花多少,PO 是已经下给供应商多少。前者 1 月才定,后者 2026 年就签完了。

还有一层:指引给的是花多少钱,市场定价的是增速还能不能加快。就算 1 月底四家给的绝对额都创新高,只要增速比今年下一个台阶,光模块的估值照样会被压——这就是为什么那份指引即使超预期,也救不了一根已经按"增速放缓"定价的 K 线。

## 反方最强的一条

反方不该是"资本开支要见顶",这个说法太粗。更强的一条是:旭创三季度 +24.6% 的环比,本身就是基数抬上来之后的高点。收入从 132 亿、195 亿、223 亿走到 278 亿,四个季度翻了一倍,越往后越难。2027 年增速只要回到 20%,46% 的毛利率就撑不住现在的估值——跌的是这个,不是订单。

这条我认一半。它解释得了估值,解释不了 11 月 6 日为什么是 PCB 和覆铜板领跌、同周美股器件厂却在涨。真要砍单,先动的应该是订单和采购承诺,不是估值。

还有一条我完全认:11 月的加速指引只锁到 12 月。云厂预算年度 1 月切换,模块订单周期一到两个季度。1 月真把全年砍了,模块厂 1 月不知道,2 月才下调。1 月是看不见的那个月,这话现在否证不了。

## 什么情况算我看错

- 旭创四季度单季毛利率跌破 45%,且不是汇率或结构的一次性因素——毛利线开始坏了,这条判断作废。
- 存货继续升、预付款继续增,但四季度收入环比不增——备货转成积压,锁料锁错了。
- 2027 年 2 月,Fabrinet 的 3 月季指引环比转负,或 Lumentum 稿里"purchase commitments exceeding $5 billion"这一档消失——锁量松动,先于指引出现。
