COHR -- Coherent Corp.

The most vertically integrated photonics company on earth. From raw materials (InP, GaAs, SiC) to lasers to transceivers to systems. Leopold's smaller position ($89M). Founded 1971 as II-VI, acquired Coherent Inc. for ~$5.7B in 2022. | AGI Score: 8 | Analysis date: 2026-03-12

Why are we looking at this?

Leopold holds ~$89M in Coherent Corp, a smaller position alongside his $479M in Lumentum. Both are optical networking plays, but Coherent is a fundamentally different animal: it is 3.5x larger by revenue ($5.8B vs $1.6B), has three diverse business segments, and is the most vertically integrated photonics company in the world -- from growing compound semiconductor crystals to shipping completed laser systems. The II-VI + Coherent Inc. merger in 2022 created a photonics superpower, but the integration is still playing out. New CEO Jim Anderson (ex-AMD/Lattice) joined June 2024 and is aggressively restructuring. The question: is Coherent a better risk/reward than Lumentum at similar market caps ($45B vs $44B)?

1. What Exactly Does Coherent Make?

Coherent is an industrial conglomerate built around photonics -- the science of controlling light. Unlike Lumentum, which focuses primarily on datacom transceivers, Coherent operates across the full photonics stack and serves diverse end markets.

Three Segments (FY2025, transitioning to two segments in FY2026)

SegmentRevenue% TotalYoY GrowthSegment ProfitMargin
Networking$3,421M59%+49%$644M18.8%
Materials$954M16%-6%$355M37.2%
Lasers$1,435M25%+3%$317M22.1%
Total$5,810M100%+23%$1,316M22.7%

Networking (59% -- The AI Growth Engine)

  • 800G/1.6T optical transceivers -- Protocol-agnostic: work with Ethernet, InfiniBand, AND NVIDIA's proprietary NVLink. This is important -- Coherent is one of the few companies qualified for NVLink.
  • Coherent transceivers -- For DCI and telecom (ZR/ZR+). Growing demand.
  • VCSELs, DMLs, EMLs, CW lasers -- The semiconductor laser chips inside transceivers. Made in-house on 6-inch GaAs and InP wafers.
  • Silicon photonics -- Next-gen platform. Co-packaged optics (CPO) capability.
  • Optical circuit switches -- Digital liquid-crystal technology. Emerging product for AI data centers.
  • Pump lasers, ROADMs, optical amplifiers -- Telecom transport equipment.

Materials (16%) + Lasers (25%)

  • SiC substrates -- Silicon carbide for EV power electronics. Market leader in 200mm semi-insulating SiC. (Declining due to EV slowdown.)
  • VCSELs for 3D sensing -- Consumer electronics (smartphones, AR/VR). One of very few vertically integrated 6-inch VCSEL manufacturers.
  • Thermoelectric coolers -- Bi2Te3 materials for temperature control.
  • Engineered materials -- ZnSe, ZnS optics for IR applications, aerospace/defense.
  • Excimer lasers -- For OLED display manufacturing (annealing).
  • Industrial lasers -- CO2, solid-state, ultrafast for semiconductor equipment, precision manufacturing.
  • Aerospace & Defense -- High-energy lasers, ISR (intelligence, surveillance, reconnaissance). Separate classified division.

The Vertical Integration Advantage

Coherent's key differentiator is depth of vertical integration. The company doesn't just make transceivers -- it grows the compound semiconductor wafers (InP, GaAs, SiC), fabricates the laser chips, makes the passive optics and isolators, designs the driver ICs, manufactures the thermoelectric coolers, and assembles the final modules. No other company in the world has this breadth. This creates several advantages: (1) cost control -- making components internally is cheaper than buying them, (2) supply chain resilience -- less dependence on external suppliers, (3) quality control -- can optimize across the full stack, (4) innovation speed -- can iterate on materials and components simultaneously. The downside is complexity and capital intensity.

2. Revenue Trajectory -- Networking Driving Growth

Coherent's quarterly revenue shows steady acceleration, though less dramatic than Lumentum's because the non-networking segments are flat/declining:

QuarterRevenueQ/Q GrowthGross ProfitGross MarginOp Income
Q2 FY2025 (Dec 2024)$1,435M--$509M35.5%$145M
Q3 FY2025 (Mar 2025)$1,498M+4.4%$528M35.2%$146M
Q4 FY2025 (Jun 2025)$1,529M+2.1%$546M35.7%$145M

Q2 FY2026 (Dec 2025)$1,686M+6.6%$623M36.9%$199M

Revenue up 17% from $1,435M to $1,686M over 4 quarters. Annualized run rate of $6.7B. The growth is entirely driven by Networking (+49% YoY) while Materials (-6%) and Lasers (+3%) are flattish. Gross margin steadily expanding from 31% (FY2024) to 37% (Q2 FY2026).

*FY2022 was the first full year post-Coherent Inc. acquisition (closed Jul 2022). Revenue jumped from ~$3.3B (II-VI standalone) to $5.2B including Coherent Inc.

FY2023-2024 were digestion years: integrating the massive Coherent Inc. acquisition, dealing with restructuring charges ($119M in FY2023), and navigating a weak telecom/industrial cycle. FY2025 shows the real earnings power emerging: revenue up 23%, operating income up 335% from $123M to $535M. But net income is only $49M due to $196M in interest expense, $160M in restructuring charges, and $85M in impairment charges. The reported EPS is negative because of preferred stock dividends to noncontrolling interest in Silicon Carbide LLC.

3. Competitive Position & Moat Analysis

Coherent's Moat Sources

Moat SourceStrengthDetails
Vertical IntegrationVERY STRONGThe deepest in the industry. Materials (InP, GaAs, SiC wafers) -> laser chips -> passive optics -> ICs -> thermoelectric coolers -> modules -> systems. No competitor matches this breadth.
IP PortfolioVERY STRONG~3,100 patents globally. Combined IP from II-VI, Coherent Inc., Finisar heritage.
Manufacturing DiversitySTRONG30,000 employees across USA, China, Malaysia, Philippines, Singapore, Vietnam, Europe. Multiple 6-inch GaAs and InP fabs. Geographic diversity provides tariff/sanctions resilience.
Customer QualificationSTRONGTwo customers >10% of revenue. Protocol-agnostic transceivers (Ethernet + InfiniBand + NVLink) = qualified across all major AI platforms.
Material ScienceVERY STRONGCompound semiconductor expertise is a genuine barrier. Growing InP and GaAs crystals at scale is extremely difficult. Very few companies globally can do this.

*LITE Cloud & Networking grew 30% annually but quarterly sequential growth rate is faster (~65% on trailing 4 quarters)

On pure fundamentals, COHR looks significantly cheaper than LITE. Nearly identical market caps but 3.5x more revenue, positive FCF, positive tangible book, lower leverage, faster networking growth, deeper vertical integration, and a lower forward P/E. The market gives LITE a premium because of its higher AI revenue purity (86% vs 59%), but that premium seems excessive -- COHR's networking segment alone does $3.4B vs LITE's $1.4B in cloud & networking.

Net Tangible Assets$0.45B-$0.39B-$1.10B$2.46B

The Goodwill Elephant

$7.68B in goodwill + intangibles ($4.47B goodwill + $3.20B intangibles) -- 51% of total assets. This is almost entirely from the Coherent Inc. acquisition in July 2022 (~$5.7B deal). The old II-VI had only $1.9B in goodwill/intangibles.

Is this goodwill real? The Coherent Inc. acquisition brought genuine strategic assets -- world-class laser technology (excimer, ultrafast, CO2), a leading position in display capital equipment, and aerospace/defense capabilities. But $4.5B of goodwill on a $5.7B acquisition suggests a huge premium was paid. If any segment underperforms, impairment risk is real (they already took $85M in impairment charges in FY2025 on assets held for sale).

Key risk: At $45B market cap and $7.7B in goodwill/intangibles, a goodwill impairment wouldn't destroy equity value, but it would signal that the merger thesis is not working. The fact that Coherent is actively divesting non-core businesses (Newton Aycliffe sale, assets held for sale) suggests management is being realistic about what works and what doesn't.

FY2025$634M-$441M$193M

Consistently FCF positive. ~$200M/year in free cash flow even during the integration/restructuring period. This is a key advantage over Lumentum (FCF negative). The company is using FCF to pay down debt.

5. The Jim Anderson Transformation

CEO Jim Anderson (joined June 2024)

Anderson's background is notable: he ran AMD's Computing and Graphics group during its turnaround under Lisa Su, then turned around Lattice Semiconductor (stock went from ~$5 to ~$90 under his leadership). He brought his CFO from Lattice (Sherri Luther) to Coherent. His playbook: simplify the organization, focus on high-growth segments, divest non-core assets, drive operational excellence.

What Anderson Has Done So Far:

The pattern: Anderson is running the AMD/Lattice playbook -- simplify, focus, execute. If he can get Coherent's operating margins from 9% (current GAAP) to 20%+ (which his segment profit margins suggest is achievable by stripping out restructuring/integration noise), the earnings power would be transformative.

For a 10x over 5 years from entry, with FY2030 bull case EPS of $10-13 at 30x P/E:

Bull Case Stock Price (2030)$300-390
10x Entry Price$30-39
Last Seen at This PriceJan-Oct 2024 ($28-45 range)

Like Lumentum, the 10x window was in early-to-mid 2024. The stock was $28-45 for most of the first three quarters of 2024. It has already done a ~6-8x from its 2024 lows. From $241, the realistic upside is 1.5-2x over 3-5 years in the bull case.

But Wait -- Why COHR Might Be Better Value Than LITE

At nearly identical market caps (~$45B), COHR has: 3.5x more revenue, positive FCF, lower leverage, faster networking growth, and a lower forward P/E (33x vs 43x). If you believe optical interconnects are the play, COHR gives you more revenue and more diversification per dollar of market cap. The main reason LITE trades at a premium is perceived "AI purity" -- but COHR's networking segment alone ($3.4B) is 2.4x the size of LITE's cloud & networking ($1.4B). The premium seems unjustified.

8. Key Risks

Bear Case Risks

  • Integration complexity -- The II-VI + Coherent Inc. merger combined two large, complex organizations. Integration is ongoing. $160M in restructuring charges in FY2025 alone.
  • $7.7B goodwill/intangibles -- 51% of total assets. Impairment risk if segments underperform. Already took $85M impairment on held-for-sale assets.
  • Non-networking segments declining -- SiC (EV slowdown), consumer electronics (smartphone VCSEL design changes), precision manufacturing (macro weakness). 41% of revenue from flat/declining businesses.
  • Chinese competition -- Same Innolight threat as Lumentum. Coherent has more vertical integration defense but still faces pricing pressure.
  • Execution risk under new CEO -- Anderson's track record is strong but he has been at Coherent less than 2 years. Large-scale transformation takes time.
  • Interest expense burden -- $196M in interest expense (FY2025). Eats into net income. Debt paydown is happening but slowly.
  • Tariffs & export controls -- 22,000+ employees in Asia-Pacific. China-specific risks from both tariffs and rare earth export restrictions.
  • Higher beta (1.91) -- Stock is more volatile than the market. Drawdowns could be severe.

Bull Case Supports

  • Deepest vertical integration in photonics -- Materials to systems. No competitor matches this breadth. Cost and supply chain advantages.
  • Protocol-agnostic transceivers -- Qualified for Ethernet, InfiniBand, AND NVLink. Positioned across all major AI platforms.
  • Jim Anderson's transformation -- Proven operator (AMD, Lattice). Simplifying structure, focusing R&D, divesting non-core.
  • Consistently FCF positive -- $193M FCF even during heavy investment/restructuring. Real cash generation.
  • Cheaper than LITE on every metric -- 8x EV/Revenue vs 22x. 33x forward P/E vs 43x. More revenue, more FCF.
  • Optionality from non-networking segments -- SiC for EVs, aerospace/defense lasers, display capital equipment. These could re-accelerate.
  • Debt paydown trajectory -- $500M paid down in 2 years. On path to investment grade.
  • 3,100 patents -- Massive IP moat across photonics, materials science, laser technology.

9. Floor Price Assessment

Floor Price: $40-60 (Low Confidence)

Unlike Lumentum, Coherent has positive net tangible assets ($0.45B) and real physical assets: $1.88B in PP&E (fabs, cleanrooms, manufacturing equipment), ~$900M in cash, plus the operating businesses generating $634M in annual operating cash flow.

Tangible Book Value Calculation:

Stockholders' Equity$8.13B
Less: Goodwill-$4.47B
Less: Other Intangibles-$3.20B
Tangible Book Value$0.45B
Tangible BV / Share (187.5M shares)$2.40

Tangible book of $2.40/share is not meaningful as a floor -- the company's value is in its operating businesses, not its balance sheet. But the operating cash flow ($634M/year) provides a floor on earning power:

Trough Operating CF$400-500MAssume 25-30% decline from current
Less: Maintenance CapEx-$250MRough estimate
Trough FCF$150-250M
Trough FCF Yield (at 3%)$5-8.3B market cap
Trough Stock Price (187.5M shares)$27-44
With 50% Margin of Safety$40-65Above trough but reasonable floor

Confidence: Low-Moderate. Better than Lumentum because there are real assets and consistent FCF, but the goodwill-heavy balance sheet and dependence on AI demand cycle make any floor estimate uncertain. The floor exists but is 75-85% below current price, making this not a floor-price opportunity.

10. Investment Verdict

COHR at $241: Better Value Than LITE, But Still Not Cheap

Coherent is the more interesting of the two optical plays. At nearly identical market caps, you get 3.5x more revenue, the deepest vertical integration in photonics, positive FCF, a proven new CEO running a transformation playbook, and a lower valuation multiple on every metric. The protocol-agnostic transceiver capability (including NVLink) positions Coherent at the heart of AI infrastructure.

Compared to Lumentum: If forced to pick one, Coherent is the better fundamental value. LITE is priced as a pure-play AI darling at 22x EV/Revenue; COHR at 8x gives you more business for less money. The market is paying a massive "AI purity" premium for LITE that seems hard to justify when COHR's networking segment alone is 2.4x larger.

The big risk is complexity. This is a company still integrating a $5.7B acquisition, restructuring aggressively, divesting businesses, and navigating tariff headwinds -- all while trying to capitalize on the AI demand wave. Jim Anderson's track record suggests he can execute, but the margin for error is thin.

Current Price$241
Very Safe Entry$40-65
Fair Value Range$200-280
5-Year Bull Case$350-450
Upside from Here (Bull)45-87%
Downside if Cycle Turns-50% to -70%
10x Entry Would Have Been$28-39 (early-mid 2024)

For Leopold's portfolio context: His $89M position in COHR is much smaller than his $479M in LITE. This could mean he views COHR as a smaller-conviction secondary play, or it could mean he views COHR as more expensive relative to his cost basis. Given both stocks were at similar prices in early 2024 ($30-45 range), the position sizing likely reflects a stronger conviction in LITE's AI purity and faster growth trajectory.

Our stance: More interesting than LITE at current prices due to better fundamental value. But still not cheap enough for our framework -- we need much lower prices to have genuine downside protection. If COHR pulled back to $100-130 (a realistic scenario in a market correction), the risk/reward would be compelling: you would be paying ~15x forward earnings for a top-3 global photonics company with AI tailwinds, consistent FCF, and an improving operating trajectory under a proven CEO.
