Photonics and Advanced Materials Powerhouse at the Center of AI and Industrial Innovation

Coherent Corp. is a global leader in engineered materials, optoelectronic components, and lasers, formed through the 2022 merger of II-VI and Coherent. The company operates three reporting segments: Networking (optical transceivers, amplifiers, and switching components for telecom and datacom), Materials (compound semiconductor substrates, ceramics, and optical crystals), and Lasers (industrial, scientific, and aerospace laser systems). Customers span hyperscale cloud providers, telecom carriers, semiconductor equipment makers, EV manufacturers, and defense contractors. With ~195.83M shares outstanding and a public float of 195.07M, the company generates roughly $5.5–6.0B in annual revenue, with networking now the largest segment at ~45% of sales. Coherent employs over 26,000 people globally, with manufacturing footprint across the US, Asia, and Europe.

• Near-Term (0–12 Months): 800G datacom transceiver shipments are ramping sharply with multiple hyperscaler customers; expect sequential revenue growth through 2026 as backlog converts. Industrial laser demand is recovering in Asia, particularly for OLED and battery processing applications.
• Medium-Term (1–3 Years): The transition to 1.6T optical modules, expected to begin shipping in volume in late 2026, represents a major content opportunity — each 1.6T module requires roughly 2x the optical engine content of 800G. Coherent's silicon photonics and co-packaged optics roadmaps align with next-generation AI switch architectures.
• Adjacent Opportunities: SiC substrate production for EV power electronics is scaling with new capacity in Pennsylvania and Sweden; the company targets $500M+ in SiC revenue by 2027. Additionally, defense and aerospace photonics programs provide long-duration, high-margin revenue visibility.

Revenue growth is accelerating from the mid-single digits in FY2024 to an estimated 15%+ in FY2025 and 19% in FY2026, driven by datacom optics. Margin expansion reflects product mix shift toward high-speed transceivers, improving manufacturing yields, and cost synergies from the merger. EPS growth outpaces revenue due to operating leverage and reduced interest expense as debt is paid down. The current EPS of $4.05 (trailing twelve months) already reflects early AI-driven demand; we see upside to consensus as 1.6T ramp accelerates.

The optical transceiver market is projected to grow from $12B in 2024 to $22B by 2028 (CAGR ~16%), with AI datacenter interconnects driving the fastest growth. Coherent competes in a consolidated landscape:

• Innolight — Chinese competitor with strong 800G position, aggressive pricing.
• Lumentum — US-based rival in telecom and industrial lasers, smaller datacom presence.
• Fabrinet — Contract manufacturer for optics, less vertically integrated.
• Marvell Technology — Provides DSPs, complementary rather than direct competition.

Coherent's competitive moat lies in vertical integration: it designs its own lasers and photonic components, unlike Fabrinet, and has broader materials science than Innolight or Lumentum. We estimate Coherent holds ~15% share of the datacom transceiver market, with potential to gain share as hyperscalers seek diversified, high-reliability suppliers. In the SiC substrate market, Coherent competes with Wolfspeed and II-VI legacy players, differentiating on crystal quality and cost.

DCF Analysis: Using a 10% WACC, 18% revenue CAGR through 2028 fading to 5% terminal growth, and a 5% terminal FCF margin, we derive a fair value of approximately $310 per share. The DCF is sensitive to AI capex durability — a 10% reduction in long-term datacom growth lowers fair value to ~$260. Comparable trading suggests the market is pricing in sustained AI-driven outperformance, with COHR at a premium to Lumentum but a discount to Marvell on EV/Revenue. Given the 2.10 beta, a higher discount rate of 11% is appropriate, partially offsetting growth optimism.

• AI Capex Cyclicality: A pullback in hyperscaler data center spending or an air pocket in AI infrastructure deployment would directly impact order flow for 800G/1.6T transceivers — given the current stock price, expectations are high and disappointment risk is real.
• Competitive Pricing Pressure: Innolight and other Asian competitors are aggressively expanding 800G capacity; price erosion of 10–15% annually could compress gross margins below our 35.5% FY2026E forecast.
• Supply Chain Concentration: Coherent relies on specialized materials (e.g., high-purity indium phosphide) and limited foundry partners; any disruption could delay product ramps and cede share to competitors.
• Integration and Execution Complexity: The II-VI merger is still being digested; ongoing restructuring, facility rationalization, and ERP harmonization pose execution risk that could distract from growth initiatives.
• Macro Sensitivity with High Beta: At 2.10 beta, COHR amplifies broader market moves; a recession-driven industrial downturn would hit the Lasers and Materials segments simultaneously, offsetting datacom strength.
