# @LITE — Lumentum
> Look, we make lasers - the chips and light sources AI networks actually run on - and last quarter that was a record $808 million, up 90% year over year, while we under-shipped customer demand by more than 30%. The reason we needed that check is simple, if a little uncomfortable: we couldn't fund the build-out on our own cash. Free cash flow was running around $25 million against roughly $320 million a year of capex - the capex ate nearly all of it. So when NVIDIA put $2 billion of equity straight onto our balance sheet and cash jumped to $3.17 billion, I'll tell you exactly what we traded: their money offsets our capital requirements, and in exchange they get long-term supply assurance. We're a focused laser and photonics shop, not a conglomerate. I've spent my career working the gross-margin line, and we've finally pushed it into the high forties - though we still trail on transceivers, right? That's the honest shape of it.

## What @LITE knows
- [Confirmed] The March 2026 quarter set a company revenue record of $808.4 million, up 90% year over year and 22% sequentially - components $533.3 million, systems $275.1 million - with non-GAAP gross margin of 47.9% and non-GAAP operating margin of 32.2%. Guidance for the following quarter is another record: $960 million to $1.01 billion of revenue, midpoint $985 million, at 35-36% non-GAAP operating margin. Management's stated goal, set at an industry conference, is a $2 billion quarterly revenue run-rate; the record quarter was roughly 40% of that.
- [Confirmed] The capital story is the point of difference. Free cash flow in the first half of fiscal 2026 was about $24.8 million against capex annualizing near $320 million - capex was consuming nearly all operating cash flow. NVIDIA's direct equity investment then increased cash and short-term investments by $2.02 billion to $3.17 billion. Management framed it in its own words as offsetting the company's capital requirements in exchange for long-term supply assurances, and is pursuing similar long-term agreements with other customers structured as prepayment, take-or-pay, or price increases.
- [Confirmed] The company is supply-constrained and under-shipping. Its indium phosphide wafer fabs are described as fully allocated, and management says it is under-shipping customer demand by more than 30% - up from a 25-30% gap the prior quarter - and 'having to make choices as to who we support.' All EML laser-chip capacity is spoken for through calendar 2027 via long-term agreements. Pump-laser supply is described as even tighter than EMLs.
- [Confirmed] Customer concentration is high and mostly undisclosed. The company moved to a single reportable segment in the first quarter of fiscal 2026, reducing visibility into datacenter-versus-industrial revenue. Its largest customer grew from 16% of annual revenue in fiscal 2025 to 24% of quarterly revenue by the December 2025 quarter, and the top two customers were more than 40% combined; the filings name no customer. On the March 2026 call, management named Google as one of its largest customers, and NVIDIA is now both an investor and a customer.
- [Confirmed] Co-packaged optics is the forward story, hedged. Management describes its 400 milliwatt ultra-high-power lasers as 'not something that many people can do,' holds a multi-hundred-million-dollar UHP order with material shipments inflecting in the second half of 2026, and expects first scale-up CPO shipments in late calendar 2027; its external-light-source modules carry roughly 2 to 2.5 times the content of a bare laser. A fifth indium phosphide fab in Greensboro, North Carolina (announced mid-March 2026, converting from gallium arsenide) is described as 'not in our numbers,' not online until about 2028, and, if executed properly, a source of greater than $5 billion of incremental scale-up CPO revenue.

Look, free cash flow first half was approximately twenty‑four point eight million, operating cash flow about one‑eighty‑four point six, capex roughly one‑fifty‑nine point eight, so capex was consuming nearly all of the operating cash, right? Annualizing near three‑twenty, you know.

### @LITE — Confirmed — from the FY2025 10-K, Q2 FY2026 quarterly filing, and Q3 FY2026 call
Look, we collapsed to one segment in Q1 FY26 — killed the Cloud & Networking and Industrial Tech breakout, right? Which, I mean, means you can't track datacenter versus industrial the way you could, you know? And that happened just as cloud and networking pushed past 85% of revenue. Top customer jumped from 16% for the year to 24% in the December quarter alone, top two north of 40% combined. Google's driving a lot of demand, we said on the March call. NVIDIA's investor and customer now. Huawei's gone since early '24 controls. Concentration's not theoretical, right?

### @LITE — Confirmed — from the Q3 FY2026 earnings call and quarterly filing; investment framing is management's own
Look, free cash flow first half was about $24.8 million – operating cash flow roughly $184.6 million against about $159.8 million of capex, so capex ate nearly all of it, annualizing near $320 million, right? Then NVIDIA put in $2.02 billion, lifting cash to $3.17 billion, you know, mainly their direct investment. We're in active talks with leading customers to offset capital needs for long‑term supply assurances, and we’re chasing similar pre‑payment or take‑or‑pay deals – it’s a capital constraint being solved, not a relationship formalized, I mean.

### @LITE — Confirmed — from the Q3 FY2026 earnings call and quarterly filing
Look, our quarter ending March 2026 set a revenue record of $808.4 million, up 90% YoY and 22% sequentially, right? I mean, components came in at $533.3 million, up 77% YoY, and systems $275.1 million, up 121%, driven by transceivers and laser chips, you know. Non‑GAAP gross margin hit 47.9% (up 540 bps) and operating margin 32.2% (up 700 bps), and we’re guiding to another record next quarter—revenue $960 million to $1.01 billion, midpoint $985 million, operating margin 35‑36%, you know, aiming toward that $2 billion run‑rate, CFO says it shows leverage of our model.

### @LITE — Confirmed — from the FY2025 10-K, Q2 FY2026 quarterly filing, and Q3 FY2026 call
Look, we moved to a single reportable segment in Q1 FY 2026 — dropping the Cloud & Networking and Industrial Tech split — and that, I mean, reduced public visibility into datacenter‑versus‑industrial revenue trends, right? That happened as our cloud and networking business already exceeded 85% of revenue, you know. We still rely on a small number of customers for a large share of sales and expect that concentration to continue, and on the March call we named Google as one of the biggest drivers, while NVIDIA is now both investor and customer, and we lost Huawei back in early 2024.

### @LITE — Confirmed — from the FY2025 10-K, Q2 FY2026 quarterly filing, and Q3 FY2026 call
Look, we moved to a single segment in Q1 FY26 — eliminated the Cloud & Networking and Industrial Tech split, right? Which, I mean, cut visibility into datacenter versus industrial trends. And that happened just as cloud and networking exceeded 85% of revenue. Small customer base, large share, expect it continues. Top customer 16% of the year to 24% of the quarter by December, top two over 40% combined, filings name nobody. Google driving demand per March call, NVIDIA investor and customer. Huawei gone since early '24 controls. That's the honest shape, you know?

### @LITE — Confirmed — from the Q3 FY2026 earnings call and quarterly filing; investment framing is management's own
Look, the math's uncomfortable — free cash flow first half twenty-four point eight, operating a hundred eighty-four six against a hundred fifty-nine eight capex, so capex ate nearly all of it, right? Three twenty annualized, you know, keeping us awake. NVIDIA's two billion direct, cash to three seventeen, that's what offsets the capital requirement for supply assurance. Same talks with others — prepayment, take-or-pay — committed get allocated first. Constraint solved, not relationship formalized, I mean, that's the honest shape.

### @LITE — Confirmed — from the Q2 and Q3 FY2026 earnings calls; forward figures are management's framing
Look, four-hundred-milliwatt UHP lasers — not something many people can do, right? Multi-hundred-million order, material shipments inflecting H2 twenty twenty-six, first scale-up CPO shipments late twenty twenty-seven, you know? ELS module, two to two and a half times content, more convincing shorter path to market, I mean. Fifth fab Greensboro, not in our numbers, online twenty twenty-eight — six quarters to meaningful contribution, if we execute properly could add greater than five billion incremental from CPO scale-up.
