Coherent Stock Rises 8% in a Month: Is the Buying Opportunity Intact?
Read MoreHide Full Article
Key Takeaways
Coherent shares gained 8% in a month as AI infrastructure demand strengthens its optical-networking outlook.
Coherent is ramping 1.6T transceivers, while 800G demand and subsystem opportunities broaden growth avenues.
COHR has fiscal 2027 demand strongly committed, with customer purchase orders extending into calendar 2028.
Coherent Corp. (COHR - Free Report) has emerged as a major beneficiary of the artificial intelligence infrastructure boom. The stock has surged 190% over the past year and gained another 8% in the past month, significantly outperforming its industry and the broader market.
Despite the sharp rally, the investment case remains supported by accelerating optical-connectivity demand, expanding manufacturing capacity and Coherent’s growing role in higher-value optical systems.

AI Infrastructure Offers a Long Growth Runway
The AI opportunity extends well beyond the construction of new data centers. Existing facilities must continually upgrade as newer GPUs, switches and networking platforms require greater bandwidth. As AI clusters expand, more connections are needed among processors, racks, switches and facilities, increasing the importance of high-speed optical networking.
This trend plays directly into Coherent’s strengths. Its portfolio includes indium phosphide lasers, VCSELs, silicon photonics, specialty fiber, detectors and micro-optics. That broad technological base gives the company multiple ways to benefit as data-center operators shift toward faster, denser and more power-efficient network architectures.
Continued improvements in AI models, falling inference costs and broader commercial adoption could further stimulate computing requirements. As AI becomes embedded in more applications, network capacity should become increasingly critical alongside computing power.
PhotonLink Expands Coherent’s Value Proposition
PhotonLink could strengthen Coherent’s position by moving the company further beyond individual components and into integrated optical subsystems. Combining internally developed technologies with integration, assembly and testing capabilities enables the company to capture a greater portion of the value created within an AI system.
This approach could also deepen customer relationships. Replacing a single component supplier is generally simpler than switching a provider whose subsystem has been designed and qualified within a broader architecture.
Coherent is also positioned across multiple technology pathways, including conventional pluggable optics, co-packaged optics, near-packaged optics and chip-to-chip connectivity. This diversified exposure reduces dependence on any single optical architecture becoming the dominant industry standard.
Coherent’s immediate earnings momentum should primarily come from products already entering large-scale production. The 1.6T transceiver ramp is particularly important, while demand for 800G products continues to expand. Co-packaged optics, optical circuit switching and Multi Rail technologies provide additional avenues for growth as AI networks become more complex.
Demand visibility is another encouraging factor. Fiscal 2027 requirements are already strongly committed, while customer purchase orders extend into calendar 2028. Longer-term agreements stretch further into the decade, with some incorporating minimum purchasing commitments and predetermined pricing.
The bigger challenge appears to be satisfying demand. Coherent increased InP laser production by nearly 80% year over year during the June quarter and continues to expand six-inch InP capacity. Higher yields from six-inch wafers could also improve manufacturing economics as volumes rise.
Earnings Momentum Supports the Investment Case
The Zacks Consensus Estimate projects fiscal 2027 revenues of $10.68 billion, indicating 50% year-over-year growth. Revenues are expected to advance another 35% in fiscal 2028.
Profit expectations are similarly robust. Fiscal 2027 EPS is projected at $9.38, indicating 67.2% growth, followed by another 46% increase in fiscal 2028. These estimates suggest that rising AI exposure, greater manufacturing utilization and operating leverage could translate strong demand into accelerating profitability.

COHR trades at roughly 32.06 times forward earnings compared with the industry’s 20.77 times. The premium is considerable, but Coherent increasingly looks different from the more cyclical hardware supplier of the past. Greater revenue visibility, stronger margins, long-term customer commitments and improving cash generation provide greater support for the valuation.

Two U.S.-Listed Peers to Watch
Lumentum Holdings (LITE - Free Report) is a relevant optical-networking peer with significant exposure to cloud and data-center connectivity. Lumentum Holdings competes in high-speed optical components and related technologies, making it sensitive to many of the AI-driven bandwidth trends supporting COHR. Lumentum Holdings therefore provides investors with another way to gauge demand across the rapidly evolving optical-networking market.
Applied Optoelectronics (AAOI - Free Report) is another U.S.-listed peer tied closely to data-center optics. Applied Optoelectronics benefits from demand for higher-speed optical products used by hyperscale customers, linking its growth prospects to expanding data-center investment. Applied Optoelectronics is therefore a useful comparison when assessing how effectively optical suppliers are converting AI infrastructure spending into revenue growth and stronger profitability.
Is COHR Stock a Buy?
Coherent appears well positioned to remain a compelling buy as AI infrastructure spending expands and optical networking becomes more critical to next-generation data centers. Demand visibility, rising high-speed transceiver volumes, broader subsystem exposure and improving manufacturing efficiency strengthen the earnings outlook. The company also benefits from a deeper role in customer architectures, which can support stickier relationships and better margins. Valuation is elevated, but the premium looks increasingly supported by faster growth, stronger profitability and long-term customer commitments. For investors willing to tolerate volatility after the rally, Coherent still offers an attractive way to participate in the AI infrastructure buildout.
