StockStory’s Take

Coherent’s second quarter results for 2026 surpassed Wall Street’s revenue and profit expectations, yet the market responded negatively. Management identified exceptional demand in the data center and communications segments, with CEO James Anderson attributing the growth to a surge in AI-driven optical networking and ongoing production capacity expansion, particularly in their 6-inch Indium Phosphide lines. CFO Sherri Luther emphasized improved cost structure and greater operating leverage as additional contributors. Despite these achievements, cautious commentary around supply constraints and industry uncertainties shaped investor sentiment.

Looking ahead, Coherent’s forward guidance is anchored by anticipated continued strength in AI data center infrastructure and the ramp-up of new product platforms including Optical Circuit Switching and co-packaged optics. Management expects further gross margin expansion, driven by cost structure improvements and increased internal capacity for Indium Phosphide. CEO James Anderson stated, "We believe Coherent is uniquely positioned to capitalize on the multiyear expansion of AI data center infrastructure," highlighting robust customer demand and significant long-term agreements as key factors supporting visibility into future growth.

Key Insights from Management’s Remarks

Management detailed that robust AI infrastructure demand and rapid capacity expansion in advanced photonics drove the quarter’s performance, while strategic investments in manufacturing and product development shaped both current results and future expectations.

• AI data center momentum: Management reported that demand for optical connectivity in AI data centers remains exceptionally strong, with the data center and communications segment accounting for 79% of company revenue and seeing 66% year-over-year growth in the quarter. The transition from copper to optical networks was cited as a foundational trend.

• 6-inch Indium Phosphide ramp: The company’s accelerated expansion of internal Indium Phosphide laser production—achieving 80% year-over-year growth in output—was described as a primary driver of improved revenue and gross margin. CEO Anderson highlighted that yields from these new 6-inch lines not only exceed those from older 3-inch lines but are critical for supporting next-generation transceivers.

• Integrated optics and product launches: Coherent is preparing to introduce the PhotonLink platform, which supports integrated optics such as co-packaged and near-packaged optics (CPO and NPO). Management described this as a “one-stop shop” solution aimed at enabling higher bandwidth and energy efficiency in data centers, with initial revenue expected in upcoming quarters.

• Long-term customer agreements: Management emphasized that customer purchase orders and long-term agreements (LTAs) now extend into 2028 and beyond, providing strong visibility for both production planning and pricing. These LTAs were described as including both volume and price commitments, supporting future financial stability.

• Industrial and communications diversification: While data center demand led the quarter, management also pointed to strengthening bookings in semiconductor capital equipment and emerging industrial applications such as data center cooling, quantum technologies, and micro LED displays. These areas are expected to support future revenue diversification.

Drivers of Future Performance

Coherent’s outlook is shaped by ongoing AI infrastructure demand, product launches in integrated optics, and continued margin expansion through operational efficiencies and manufacturing scale.

• AI-driven capacity ramp: The company’s guidance assumes sustained high demand for AI data center connectivity, with expanded production capacity in Indium Phosphide lasers expected to enable higher transceiver output and support revenue growth. Management views the ramp of new products—such as 1.6T transceivers and optical circuit switches—as essential to reaching future revenue milestones.

• Product and platform innovation: The upcoming launch of the PhotonLink platform and ramping of co-packaged and near-packaged optics are expected to open new addressable markets, enabling Coherent to participate in both scale-out and scale-up data center architectures. These innovations are projected to drive incremental revenue and improve product mix.

• Margin expansion and risks: Management expects gross margin improvements from the migration to 6-inch Indium Phosphide and operational efficiencies, but cautioned that the pace of improvement will depend on the timing of new product ramps and ongoing cost control. External factors such as potential import restrictions and competitive pressures, particularly from international players, are also being monitored as possible risks.

Catalysts in Upcoming Quarters

In the quarters ahead, the StockStory team will be watching (1) the pace of Indium Phosphide capacity expansion and its effect on transceiver shipments, (2) the rollout and customer adoption of the PhotonLink integrated optics platform, and (3) the scaling of Optical Circuit Switching and multi-rail systems as new revenue streams. Progress in industrial diversification and execution against long-term customer agreements will also serve as key indicators of sustainable growth.

Coherent currently trades at $345.80, down from $358 just before the earnings. Is the company at an inflection point that warrants a buy or sell? See for yourself in our full research report (it’s free).
