Coherent Corp

COHR

NEUTRAL

May 29, 2026

Research Conclusion

At $377 per share (May 2026), Coherent Corp is a high-quality, well-positioned AI infrastructure equity trading at the upper end of defensible fair value. The composite valuation range of $230–$355 sits 6-39% below the current price, while a probability-weighted fair value of $301 implies ~20% downside. The investment thesis (transceiver supercycle + non-linear deleveraging + SiC/defense optionality) is correct and durable, but the market has substantially priced these tailwinds. The verdict is NEUTRAL/HOLD at current pricing, with accumulation appropriate below $280 and trimming appropriate above $400.

Company Overview & Moat Assessment

Coherent Corp (NYSE: COHR) is a vertically integrated photonics and compound semiconductor manufacturer formed by the January 2022 merger of II-VI Incorporated and legacy Coherent Inc. The company operates three segments—Networking (~60%, optical transceivers for AI data centers), Lasers (~20%, fiber/ultrafast/defense lasers), and Materials (~20%, SiC and compound semiconductor substrates)—with FY2025 revenue of $5.81B (+23% YoY), $1.66B LTM EBITDA, and net debt of ~$2.5B at 2.1x leverage. CEO Jim Anderson (appointed June 2024) is executing a portfolio simplification, deleveraging, and margin expansion playbook. Headquartered in Saxonburg, PA with 26,000+ employees.

▲ Bull Case

  • 1.6T market share exceeds consensus: Coherent's unique tri-architecture portfolio captures 25-30% of 1.6T (vs 15-20% consensus), driving $500M-$1B incremental Networking revenue by FY2027.
  • SiC inflection materializes: Wolfspeed-displaced volume converts to qualified Coherent supply, lifting Materials segment from -4% (FY2025) to +20-30% growth (FY2027-FY2028), with 25-35% global SiC substrate share.
  • Defense laser business monetizes: DoD directed energy programs grow to $600-800M+ by FY2027 as DEAM, HELIOS, and IFPC-HEL contracts ramp, combined with deleveraging-driven multiple expansion reaching $550-650/share (22% probability).

▼ Bear Case

  • AI capex normalization: Hyperscaler combined capex plateaus or declines 15%+ in 2026, triggering a 20-25% Networking revenue correction and channel inventory build.
  • Chinese competition arrives at 800G: InnoLight/HG Genuine/Eoptolink achieve 800G hyperscaler qualification, compressing ASPs 25%+ and stalling Coherent's gross margin expansion to 42% target.
  • Multiple compression: AI infrastructure sentiment fades and EV/EBITDA contracts from ~40x to 15-20x, representing ~50% equity destruction and driving stock to $120-180/share (28% probability).
Primary Debate on Wall Street

The 20-25 analyst consensus reflects strong buy bias with PT range $200-$500+—a remarkably wide dispersion capturing the central debate. The bull camp argues the AI infrastructure cycle is multi-decade, Coherent's vertical integration creates a structural moat at each generational transition, and the SiC/defense optionality is underpriced. The bear camp argues multiples are unsustainable, 800G shows channel inventory signals, Chinese competition is closer than the moat narrative suggests, and the merger-leveraged balance sheet amplifies downside. Both camps agree that 1.6T execution and FY2026 H1 margin trajectory are the most important near-term data points. Wall Street is debating price, not thesis validity.

Top Catalysts
  • Q1 FY2026 earnings (October 2025)—first quarter with meaningful 1.6T contribution; tests revenue and gross margin trajectory.
  • Hyperscaler quarterly capex guidance (Microsoft, Google, Meta, Amazon, Apple)—leading indicator for AI demand.
  • NVIDIA data center revenue prints—direct proxy for AI cluster buildout pace.
  • 1.6T quarterly revenue ramp—sequential growth validates execution; below $200M/qtr through FY2026 Q3 triggers assumption reset.
  • SiC market share visible signals—major OEM (Toyota, Honda, STMicro) publicly naming Coherent as primary supplier.
  • Net leverage reaching 2.0x—could trigger credit rating upgrade and multiple expansion.
  • 3.2T transceiver development milestones—extends thesis duration beyond FY2027.
  • DoD directed energy contract awards—confirms Step 16 variant view on defense laser monetization.
Top Risks
  • AI capex deceleration (Medium probability, HIGH severity)—hyperscaler plateau/decline triggers revenue correction.
  • Valuation multiple compression (Medium probability, HIGH severity)—EV/EBITDA contraction from ~40x to 15-20x represents ~50% equity destruction.
  • 1.6T ramp execution (Low-Medium probability, MEDIUM-HIGH severity)—qualification delays or lower-than-expected adoption.
  • Chinese competition at 800G (Low-Medium probability, MEDIUM severity)—InnoLight/HG Genuine qualification compresses ASPs 25%+.
  • Balance sheet stress (Low probability, MEDIUM-HIGH severity)—if EBITDA declines, net leverage rises above 3.0x without clear path.
  • Customer concentration with hyperscalers (HIGH severity)—top-5 buyers concentrate demand; single-customer loss is material.
