Capacity Release and New Product Ramp Drive Material Upward Revision to Coherent's FY27 Growth Outlook

Overview

Coherent's F4Q26 results exceeded expectations for revenue, gross margin, and earnings. JPMorgan believes the company is converting strong demand for data-center optical interconnects into faster growth: expanding internal InP capacity will support 800G and 1.6T transceiver supply, while OCS, CPO/NPO, and multi-rail products will progressively contribute incremental revenue in FY27. Based on improved demand visibility and expectations for continued margin expansion, JPMorgan reiterates Overweight and raises its target price.

Core views

The core investment thesis is the simultaneous improvement in supply capability and demand growth. Internal InP supply replacing higher-cost external supply is expected to improve gross margins, while a higher-value new product mix can further enhance profitability. FY27 revenue guidance and expectations for nearly 50% full-year growth reflect accelerating growth from the data-center business and new product ramp; however, the market may still focus on the relatively modest sequential gross-margin improvement implied by F1Q27 guidance.

Analysis framework

The report bases its assessment on quarterly results relative to JPMorgan and market consensus expectations, management's next-quarter guidance, the pace of capacity ramp-up, product revenue ramp paths, and forward financial forecasts, and uses a forward P/E methodology to set the target price.

Methodology notes

• Valuation MethodologyP/E Valuation Method

  Estimate the target price by multiplying forward earnings per share by a target P/E multiple

  The $465 target price is based on updated CY28E EPS and an approximately 30x target P/E multiple; this multiple is above long-term average levels and the historical average of optical communications comparables, reflecting the company's benefit from AI data-center investment.

• Earnings AnalysisExpectation Gap Analysis

  Compare actual results, institutional forecasts, and market consensus expectations

  The report compares F4Q26 revenue, gross margin, and EPS with JPMorgan forecasts and market consensus, and assesses the upside of F1Q27 guidance relative to expectations.

• Operational AnalysisCapacity and Product Ramp Analysis

  Assess future revenue and margins based on the expansion of critical capacity and the pace of product introduction

  The increase in internal InP capacity is the key factor easing supply constraints on transceiver revenue expansion; the introductions of OCS, CPO/NPO, and multi-rail products are viewed as drivers of incremental FY27 growth and margin improvement.

  Core Covered Name

  Strengths

  Strong data-center optical interconnect demand; expanding internal InP capacity eases supply constraints; 800G/1.6T transceivers, OCS, CPO/NPO, and multi-rail products provide diversified growth sources; high FY27 order visibility.

  Weaknesses

  The sequential improvement implied by F1Q27 gross-margin guidance is relatively modest, and the degree of near-term margin acceleration still requires validation.

  Comparison

  Target valuation is approximately 30x CY28E P/E, above long-term averages and the historical average valuation of optical communications peers, reflecting its positioning as an AI data-center beneficiary.

  Risks

  Industry pricing pressure, customer vertical integration, weaker-than-expected acquisition integration execution, and delays in capacity or new product ramp-up.

• Target Price$465Raised from the prior $435, based on approximately 30x CY28E EPS.

Impact & implications

If InP capacity is released as planned and 1.6T transceivers and new products ramp successfully, Coherent could gain stronger revenue and earnings leverage from AI data-center capital spending. Longer order coverage improves short- to medium-term forecast visibility; meanwhile, internal supply substitution and product-mix optimization are key to advancing gross margins toward the above-42% target. Valuation already reflects part of the growth expectations, and subsequent earnings delivery, gross-margin acceleration, and new product revenue ramp will be the main conditions for sustaining the valuation premium.

Risks

• Pricing pressure may intensify as optical industry technologies mature, potentially reducing revenue, earnings estimates, and the target price.
• Optical transport system suppliers may increase vertical integration, raising competitive and pricing pressure on optical component suppliers.
• Recent acquisition integration carries execution risk, which may affect industrial laser business synergies and earnings improvement.
• If internal InP capacity expansion, 1.6T transceivers, and new product introductions fall below plan, growth expectations may not be realized.
• Changes in the pace of AI data-center investment or customer demand could affect orders and revenue growth.

What to watch

• Whether F1Q27 revenue, gross margin, and adjusted EPS reach or exceed the guidance midpoint.
• Execution progress toward doubling internal InP output by the end of F1Q27 and doubling it again by the end of CY27.
• Shipment volumes of 800G and 1.6T transceivers and year-over-year growth in data-center revenue.
• OCS growth in FY27, as well as the initial revenue contribution from CPO/NPO in F2Q27 and multi-rail products in the first half of CY27.
• Whether gross margins can continue moving toward the above-42% target through internal supply substitution and product-mix improvement.
• The continuation of order coverage, CY28 purchase orders, and long-term agreements.
