New York, March 3, 2026, 12:20 (EST) — Regular session
Coherent Corp. (COHR) shares fell 3.5% to $288.44 in midday trading on Tuesday, giving back part of the prior session’s jump after Nvidia agreed to invest $2 billion in the photonics maker. The stock has traded between $271.95 and $290.20 so far in the session.
Coherent closed up 15.4% on Monday after Nvidia laid out a multiyear optics deal that put the company on the short list of suppliers tied directly to next-generation AI data centers. Tuesday’s pullback showed early profit-taking after the rally, with investors also weighing the mechanics of a large equity issuance. 1
The companies said their nonexclusive agreement includes a multibillion-dollar purchase commitment and “access and capacity rights” for advanced laser and optical networking products — the sort of components needed to move huge volumes of data inside AI clusters. Nvidia CEO Jensen Huang said the pair are “pioneering next-generation silicon photonics,” a term for using light rather than electricity to shuttle data between chips. Coherent CEO Jim Anderson called it an expansion of the firms’ “20-year relationship” with Nvidia. 2
A regulatory filing showed Coherent sold 7,788,161 shares to Nvidia at $256.80 each in a private placement — a stock sale outside the public market — raising $2 billion in cash. Coherent said it expects the proceeds to support research and development, capacity expansion and operations as it expands a U.S. manufacturing footprint, and it disclosed a collaboration that gives Nvidia access to five additional Coherent product families tied to co-packaged optics. 3
Co-packaged optics, often shortened to CPO, pushes optical engines closer to the compute package to cut heat and power use as bandwidth climbs. Investors are watching for signs that supplier “access” turns into recurring orders, not just headlines.
The slide was not isolated. Lumentum (LITE) was down 8.9% and IPG Photonics (IPGP) fell 1.3%, while Nvidia (NVDA) shares were off about 1.3%.
Brendan Burke, a research director at Futurum, wrote that Nvidia’s twin investments in optics suppliers suggest photonics is emerging as a supply-chain choke point for AI infrastructure, not a nice-to-have upgrade. He flagged limited capacity for indium phosphide lasers, a key input for high-speed optical links. 4
But the risks are plain. A discounted share sale dilutes existing holders, and scaling advanced optics manufacturing can take time and capital — with no guarantee that customer demand stays this hot if data center spending slows or orders spread across rival suppliers.
What comes next is near-term and specific. Coherent is scheduled to present at Morgan Stanley’s 2026 Technology, Media & Telecom Conference later Tuesday, and it has a Technology Innovation Briefing set for March 17. Traders will be listening for anything concrete on production ramps, timing, and how quickly the Nvidia-linked demand shows up in revenue. 5
