Coherent Stock Has The Bull Case Changed After New AI Optics Launches?

• Coherent introduced its PhotonLink integrated optics platform and expanded Pluggable Optical Line System offerings at ECOC 2026. The company showcased CPO, NPO, chip to chip connectivity and high-capacity optical transport for AI datacenters, supported by vertically integrated manufacturing and capacity expansion in indium phosphide and specialty fiber.
• The PhotonLink launch, together with live AI datacenter demos and more than ten CPO and more than ten NPO customer engagements, indicates that Coherent is committing significant resources to become a single-vendor provider of critical optics for large scale AI infrastructure buildouts.
• We will now examine how Coherent’s PhotonLink platform and broader AI datacenter optics initiatives could influence the existing investment narrative.

Coherent Investment Narrative Recap

To own Coherent, you need to believe its heavy focus on AI datacenters and communications can remain the engine of the group while more cyclical industrial areas stay manageable. PhotonLink and the expanded Pluggable Optical Line System point to an operating plan centered on high speed optics, where execution on capacity ramps and customer programs is the key near term catalyst.

The biggest risk is that large capex and vertically integrated manufacturing may not translate into sustained, profitable volume if hyperscaler demand or pricing shifts. Recent announcements help frame the opportunity but do not resolve exposure to customer concentration, intense transceiver competition, or the financial strain of continual investment.

The PhotonLink launch is the clearest operational hinge for this news cycle. Coherent is aiming to offer a full optics path for AI datacenters, from indium phosphide lasers and VCSEL arrays through silicon photonics, specialty fiber and complete modules, supported by expanded 6 inch InP and fiber capacity. That puts execution quality on this platform at the center of the story.

For you as an investor, PhotonLink cuts directly into the main catalyst and the main risk. If customer engagements around CPO, NPO and chip to chip links convert cleanly into revenue ramps and cash generation, the heavy build out of manufacturing looks more justified. If qualification cycles slip or pricing pressure increases, those same fixed investments could weigh on returns.

Coherent's current analyst narrative points to US$19.2b in revenue and US$3.5b in earnings by 2029, based on assumed yearly top line expansion of 39.2% and an earnings increase of about US$2.7b from US$769.9m today.

Uncover why Coherent's fair value indicates a 44% potential upside to its current price before that discount starts to close.

Exploring Other Perspectives

One bullish twist in the Coherent story is how aggressively the highest analysts lean into AI datacenter optics as a long runway. They were already penciling in about US$24b of revenue and US$3.8b of earnings by 2029 before PhotonLink surfaced.
