My main takeaway was that your merchant CW laser suppliers seem to be EXTREMELY IMPORTANT now.
But TLDR of $COHR earnings:
"given the demand that we see in our DC business with transceivers, I don’t see any time in the near future where we would be selling indium phosphide lasers externally"
Ton more value placed on companies that sell InP lasers externally if $AAOI can't doesn't enough capacity for first gen-CPO deployments, $COHR not selling externally...
I guess that's why $MTSI said a ton of customers are approaching them with urgency for InP CW DFB lasers (and they dont even have meaningful capacity coming online until EOY 2027)
$AAOI -> Internal $COHR -> Internal Buyers -> fewer places to look for capacity.
"Our backlog now extends out, fiscal 2027 is basically completely booked out. We are booked really through the end of calendar 2027" [ Massive massive demand visibility]
Coherent also mentioned LTAs spanning end of decade. So this kinda reinforces what $POET CEO said at their AGM that the "big 3" are fully sold out next 2 years.
"we’re not constrained in the assembly and test capacity right now. We’re really just constrained by the ramp of the indium phosphide production"
Just for the bottleneck bros in terms of assembly/test not a bottleneck.
"absolutely no push-out of CPO demand. In fact, it has been the opposite. We have seen demand increase and request from customers’ demand getting pulled in"
"we continue to expect revenue from CPO for scale-up applications to start to flow in the second half of calendar 2027"
Big read through on other CPO players for scale up if $LITE, $COHR reaffirm revenue from CPO scale up coming h2027.
"quarterly revenue exceeding $3 billion by the end of fiscal 2027"
$COHR revenue go brrr
So for regular numbers it's:
$2.046B revenue (+13.3% Q/Q, +33.8% Y/Y), main revenue ramp looks to be happening entering Q4 into 2027
Non-GAAP gross margins: 40.2%
Next quarter guide is:
Revenue: $2.2–$2.4B revenue
Non-GAAP gross margins: 39.5-41.5%
Basically: $1.69B -> $1.81B -> $2.05B -> ~$2.30B -> $3.0B (end of FY 2027) ~39% -> 39.6% -> 40.2% -> ~40.5% (gross margins)
For operating margins: 18.0% -> 19.5% -> 19.9% -> 20.3% -> 21.8%
Little less impressed compared to $LITE margin growth in terms of profitability, but revenue scale for $COHR growing rapidly.

Serenity 的核心判断是，能对外销售的 merchant CW laser suppliers 现在更重要。Coherent 的数据中心 transceiver 需求已经吸收了内部 InP 产能，近期没有对外销售 InP lasers 的空间。若 AAOI 也没有足够产能参与 first-gen CPO，买方能寻找的外部供给就会更少。

他把 MTSI 提到的客户紧急询价、Coherent 的 backlog 和 CPO 需求拉动放在同一条证据链上。这里能确认的是行业需求、Coherent 内部产能约束和 CPO 时间表表述。$SIVE 是否属于这组 merchant CW laser suppliers，仍缺客户、订单、出货与收入确认文件。

Coherent 官方业绩稿确认 FY2026 Q4 revenue 为 $2.05B，non-GAAP gross margin 为 40.2% 2。电话会转录记录了管理层关于 external InP lasers、calendar 2028 backlog、长期协议、assembly and test capacity、InP production ramp 和 CPO scale-up revenue 的表述 3。
