What Are the Key Operations Driving Mersen’s Success?
Mersen designs and manufactures critical components that protect, conduct, convert and cool electrical power, and engineers advanced graphite and composite materials for extreme environments, serving power electronics, EV, renewables, semicon and chemical industries.
Core product lines
Low- and medium-voltage fuses and fusegear, overvoltage/surge protection, laminated busbars and current collectors form the electrical protection and conduction portfolio.
Thermal and cooling solutions
Cooling plates and heat sinks for power electronics reduce junction temperatures and extend life of inverters, converters and traction systems.
Graphite and composites
Isostatic graphite, carbon/carbon composites and SiC‑coated graphite serve high‑temperature, corrosive and semiconductor process applications.
Anti‑corrosion equipment
Heat exchangers, columns and packing for chemical and pharmaceutical plants offer corrosion resistance and long operational life.
Mersen operates vertically where it matters: raw graphite production, precision machining, coatings such as SiC, lamination for laminated busbars, metal fabrication and final assembly, plus on‑site application engineering and standards support to secure design‑ins.
Differentiation and value propositions
The company delivers reliability in harsh environments, safety certifications and life‑cycle support that lower customers' downtime and total cost of ownership.
- Vertically integrated manufacturing and multi‑site redundancy across Europe, North America and Asia
- Strategic sourcing of petroleum coke, resins, copper/aluminum and silicon carbide to secure supply
- Long‑term contracts with semiconductor and chemical customers, supporting predictable revenue
- Application engineering, qualification support and compliance with IEC and UL standards
Customer segments include power electronics OEMs, EV charging and renewable systems, rail and aerospace, semiconductor equipment makers, battery and solar producers, and chemical/pharma plants; 2024 reported revenue mix showed industrial electrical and advanced materials exposure with continuing growth in EV and semicon end markets.
Distribution uses direct key‑account sales for OEMs, global electrical distributors and panel‑builder channels; intellectual property in materials science, demonstrated field reliability and certifications underpin premium positioning and recurring serviceable revenues—see Mission, Vision & Core Values of Mersen for related corporate context.

How Does Mersen Make Money?
Revenue Streams and Monetization Strategies center on product sales across two families—Advanced Materials and Electrical Power—plus engineered systems, aftermarket services, and design‑in activities that drive recurring, higher‑margin business.
Core product sales
Group revenue in 2024 was approximately €1.2–€1.3 billion, split roughly 55–60% Advanced Materials and 40–45% Electrical Power.
Engineered systems
Custom graphite heat exchangers, reactors, and thermal assemblies generate higher gross margins through engineering content and aftermarket pull‑through.
Aftermarket & spares
Replacement fuses, surge modules and graphite components form recurring revenue, estimated at low‑to‑mid teens percent of sales with strong margin contribution.
Design‑in & application engineering
Monetized via product pricing and project scopes rather than standalone fees; creates multi‑year, sticky OEM relationships once qualified.
Regional revenue mix (2024 est.)
EMEA ~35–40%, Americas ~30–35%, Asia‑Pacific ~25–30%, with semicon‑exposed Asia and U.S. power‑electronics/EV infrastructure driving growth.
Pricing & bundling
Tiered fuse portfolios, bundled busbar+cooling solutions, and value‑based pricing on SiC‑coated graphite amid capacity tightness expand wallet share per platform.
Revenue mix has shifted toward semiconductors, batteries and renewables over the last three years, raising ASPs and margins; management indicated continued mix improvement into 2025 as electrification ramps.
Monetization levers
Key levers that sustain and grow revenue streams across the Mersen company business model include premium products, engineering services, and recurring aftermarket sales.
- Product sales: Advanced Materials (wafer‑fab, battery, solar) and Electrical Power (EV charging, inverters, rail)
- Engineered systems: Higher margins from custom graphite equipment and thermal assemblies
- Aftermarket & services: Low‑to‑mid teens percent of sales with strong gross margin impact
- Design‑in: Embedded value in OEM projects that secures multi‑year demand

Which Strategic Decisions Have Shaped Mersen’s Business Model?
Key milestones from 2023–2025 show capacity expansion in semiconductor materials, scaled electrification components, portfolio optimization, and supply‑chain resilience that strengthened backlog and OEM qualifications.
Semiconductor upcycle capture
Expanded graphite and SiC‑coated part capacity; secured multi‑year agreements for deposition, implant and diffusion tools with backlog sustained into 2025 despite node transitions.
Electrification build‑out
Scaled laminated busbars and liquid‑cooled plates for EV inverters/chargers and utility inverters; product qualifications with leading OEMs broadened across 2023–2024.
Portfolio optimization
Prioritized higher‑margin advanced materials and engineered protection; disciplined capex in coatings, isostatic graphite and precision machining to relieve bottlenecks.
Supply chain resilience
Dual‑sourcing and regionalized manufacturing reduced logistics and geopolitical risk; operational excellence programs preserved service levels through 2022–2024 disruptions.
The company leverages materials science, certifications and high switching costs from OEM design‑ins to sustain margins while aligning capex with secular growth in EVs, renewables and semiconductors.
Competitive edge and strategic moves
Competitive advantages include deep engineering know‑how, safety and application standards, and economies of specialization in mission‑critical parts; strategic moves focus on embedding with next‑gen platforms.
- Deep materials science expertise enabling advanced graphite and SiC coatings
- High switching costs after OEM design‑in for fuses, busbars and custom components
- Regional production and dual‑sourcing to protect margins and delivery
- Capex aligned to EV, renewables and semicon growth with expanding aftermarket services
Financial and operational indicators up to 2024–2025: capacity expansions targeted to raise production output by double digits in coated parts and laminated busbars; multi‑year OEM contracts underpin recurring revenue; margins improved where advanced materials represent a larger share of sales.

How Is Mersen Positioning Itself for Continued Success?
Mersen holds leading positions in industrial fuses, surge protection and laminated busbars in Europe and globally strong shares in thermal management and specialty graphite for semiconductors, supported by long qualification cycles and recurring platform business across 35+ countries.
Industry position
Mersen company is a top‑tier supplier in industrial fuses and surge protection in Europe and a leader in laminated busbars, thermal assemblies and specialty graphite for semicon and harsh‑chemistry equipment worldwide.
Market reach
Customers span over 35 countries; long qualification cycles (typically 3–5 years) and multi‑year platform lifecycles support resilient repeat business and high OEM design‑in retention.
Key risks
Principal risks include semiconductor capex cyclicality, raw‑material price volatility (graphite precursors, metals), competitive pressure from global fuse and materials players, and regulatory changes in grid and rail standards.
Financial exposures
Currency exposure (EUR vs USD/CNY) can materially affect reported growth; a slowdown in EV or renewables deployment would weigh on the Electrical Power segment and aftermarket timing.
Management outlook and actions for 2025 focus on capacity additions and mix uplift toward semicon and electrification while expanding aftermarket services and maintaining disciplined capex.
Outlook and growth drivers
With secular trends in power electronics, grid modernization, EV infrastructure and wafer‑fab investments, Mersen targets organic growth, margin accretion from engineered solutions and monetization through deeper OEM design‑ins.
- 2025 priorities: expand coated graphite and thermal assembly capacity and pursue mix upgrade toward semicon/electrification
- Revenue mix shift expected toward higher‑margin engineered products and aftermarket services
- Key sensitivity: semiconductor capex cycles and raw material cost swings
- Operational levers: design‑in expansion, service revenue growth, and selective, disciplined capex
