Innolight (中际旭创) raised HK$53.4 billion in Hong Kong's largest IPO since Alibaba's 2018 listing, but grey-market shares already slipped 3.8% as AI valuations face a reality check.

01

How big is this IPO?

The deal raised HK$53.4 billion (about US$6.8 billion), the largest Hong Kong listing since Alibaba's secondary offering in 2019.
Shares priced at HK$980 each, an 11% discount to Innolight's concurrent A-share price. This means → Hong Kong investors got a cheaper entry, but the discount itself signals the market is split on where valuation should sit.
Cornerstone investors committed roughly US$3.45 billion with a six-month lock-up. The lineup: Temasek, Hillhouse, J.P. Morgan Asset Management, and BlackRock.
02

Why is AI sentiment cooling?

Innolight makes optical transceivers for data centres — devices that convert electrical signals between servers into light, essentially the "nerve fibres" of AI infrastructure.
Its A-share price has fallen more than 30% from the June peak, despite doubling from early April. In plain terms = the market priced in peak AI expectations first and is now verifying them trade by trade.
Charlie Hong, founder and CIO of LOGOS Asset Management, put it this way: "The long-term thesis still holds, but short-term conviction has softened on concerns about hyperscaler capex outlook and the pace of technology adoption."
03

Do the fundamentals hold up?

Q1 2026 revenue hit RMB 19.5 billion (about US$2.9 billion).
The top three customers — Alphabet, Amazon, and Meta — accounted for roughly 40% of revenue. This means → earnings are heavily concentrated in US tech giants, and order stability is directly tied to their capex plans.
Institutional tranches were oversubscribed by several times; the company closed its institutional book a day early — demand, for now, is not the issue.
04

How large is the geopolitical risk?

Guotou Securities analyst Wang Yang noted that US-market revenue rose to 61.7% of the total in Q1.
This reflects a structural tension: the stronger the business grows, the deeper its US dependence — and the greater its exposure to export controls.
In plain terms = Innolight's most profitable market is also its most geopolitically uncertain one — and that is the core variable capping its valuation.
05

Where will the proceeds go?

Funds are earmarked for R&D, capacity expansion, supply-chain improvements, M&A, and working capital.
With more large IPOs in the pipeline, Hong Kong's total IPO proceeds this year could hit a six-year high.
For Innolight, the key test ahead is whether its US-concentrated revenue mix can hold steady under export-control pressure — the market will treat that as the pivotal checkpoint for long-term valuation.
