Stars
EV and power electronics cooling solutions
High-growth, high-share: as electrification ramps across autos, storage and industrial drives—global EV sales reached 14 million in 2023 (IEA)—Mersen’s liquid and air-cooled plates sit in specs for leading inverter and battery platforms. They require heavy upfront capital for custom engineering and tight thermal performance, so they consume cash while scaling. Keep feeding them; they should become Cash Cows once market growth normalizes.
Semiconductor process graphite and high‑temp materials
Wafer fabs are booming—TSMC alone planned $32–40B capex for 2024—driving structural demand for graphite, insulation, and thermal components where Mersen is entrenched. Strong multi-year qualifications and long supply cycles lock in share at top OEMs and fabs. Demand is volatile but up with AI, SiC, and broad capacity additions. Mersen should invest to expand capacity and protect lead times.
Renewables and grid surge protection (utility‑grade)
Wind, solar and grid-scale storage increasingly require utility-grade surge and transient protection as 2024 sees accelerating deployments and fast-growing spend on grid resilience.
Mersen’s engineered devices and coordination studies provide an edge with EPCs and utilities where project specs are sticky and bids remain competitive.
Maintaining leadership depends on scaling field support and digital design tools to win large, specification-driven projects.
Rail and e‑mobility high‑power busbars and fusing
Urban rail and e‑bus fleets are electrifying now: global electric bus fleet topped about 750,000 units in 2024 and new orders were >60% electric, driving immediate demand for high‑power components. Mersen’s laminated busbars and high‑rupture fuses are specified into traction systems and chargers, with design wins across OEMs. Lengthy certification and integration cycles raise switching costs, sustaining share; scale platform wins and 24/7 service SLAs globally to lock growth.
- Market: global e‑bus fleet ~750,000 (2024)
- Adoption: >60% of new e‑bus orders electric (2024)
- Product: laminated busbars + high‑rupture fuses specified in traction/chargers
- Moat: certification complexity = high switching cost
- Strategy: expand platform wins + global SLAs
SiC device thermal management and packaging materials
SiC power electronics are scaling rapidly in EV inverters and DC fast chargers, shifting heat flux limits into the 100s W/cm2 as the primary choke point; Mersen’s advanced coolers and high‑thermal‑conductivity dielectrics deliver proven reliability and lifetime in fielded Tier‑1 designs, supporting higher switching frequencies and >95% system efficiency. Double down on co‑development with device makers to cement leadership.
- SiC adoption: rising in EVs/chargers
- Thermal: heat flux hundreds W/cm2
- Mersen: Tier‑1 design‑ins, proven reliability
- Strategy: scale co‑development
Electrification & fab capex fuel demand for thermal, graphite and protection — prioritize capacity
High-growth, high-share: electrification (global EVs 14M in 2023; e‑bus fleet ~750k in 2024) and wafer fab capex (TSMC $32–40B planned 2024) drive demand for Mersen’s thermal, graphite and protection products. These require upfront capital and consume cash while scaling but have long qualification cycles and high switching costs, poised to become cash cows as growth normalizes. Prioritize capacity, co‑development and 24/7 SLAs.

Cash Cows
Industrial fuses for low‑voltage protection
Industrial low‑voltage fuses are a mature, global cash cow for Mersen, underpinning steady replacement cycles and contributing to the group’s scale (Mersen reported ~€1.06bn revenue in 2023). High market share across geographies and broad distribution reduce need for heavy promotions—customers buy on spec compliance and availability. Focus on optimizing footprint, maintaining fill rates above industry benchmarks, and milking margins.
Carbon brushes and holders for industrial motors
Large installed base of industrial motors—commonly cited at over 500 million units worldwide—keeps aftermarket demand for carbon brushes and holders durable; brushes remain recurring MRO buys with stable unit volumes. VFD and brushless adoption is growing roughly 5–7% annually, slowing segment growth but not causing rapid obsolescence. These products generate predictable cash flow and margins; focus should be on service-led sales, SKU simplification, and disciplined pricing to protect profitability.
Chemical process equipment graphite blocks and exchangers
Chemical process equipment graphite blocks and exchangers act as Mersen cash cows: replacement and maintenance drive repeat orders in a mature niche, with 2024 demand stable across legacy chemical plants. Mersen’s material know-how yields defensible margins and high aftermarket stickiness. Capex cycles are lumpy but the installed base ensures recurring revenue. Prioritize efficiency and lead‑time reductions over heavy promotion.
Panel‑level surge protection for commercial buildings
Panel-level surge protection for commercial buildings is a code-driven, spec-based cash cow in a stable market; Mersen benefits from strong contractor and OEM panel brand recall, driving dependable reorder behavior with low organic growth and margin stability. Maintain close channel relationships and execute incremental product refreshes to preserve share and profitable recurring revenue.
- Code/spec-driven purchases
- Trusted brand with contractors/OEMs
- Low growth, steady reorders
- Maintain channels, incremental refreshes
Standard laminated busbars for industrial drives
Standard laminated busbars for industrial drives are a Cash Cow: OEM integrations are long‑lived, low visibility and deliver stable replacement and retrofit demand; market tied to industrial capex with an estimated 2024 CAGR around 2–4%, supporting steady volumes. High share in core regions and amortized engineering spend mean strong EBITDA conversion if yields remain high and scrap stays minimal.
- Long‑lived OEM contracts
- Market growth ~2–4% (2024)
- High regional share; engineering payback achieved
- Protect margin by maximizing yields, minimizing scrap
Cash-core industrial parts: €700–750m, margins 12–22%
Mersen cash cows deliver predictable EBITDA and cash: industrial fuses, carbon brushes, graphite exchangers, surge protection and laminated busbars drove ~€700–750m recurring revenue in 2024, margins 12–22% and growth 0–4%—focus on uptime, fill‑rates, SKU rationalization and lead‑time cuts to maximize cash conversion.

Dogs
Legacy commodity fuses in price‑only segments
Legacy commodity fuses in Mersen’s price-only segments face a race-to-the-bottom on SKUs with heavy low-cost competition; global low-voltage fuse markets grew under 2% in 2024, amplifying pricing pressure. Low growth and little differentiation keep gross margins compressed—often below 10% in commodity tiers—while cash and working capital remain tied in slow-turn SKUs. Prune long tail SKUs or exit lowest tiers to free ~5–10% of tied-up working capital and restore margin focus.
Coal and legacy thermal power protection parts
Decarbonization has pushed coal and legacy thermal fleets into decline, with over 40 countries committing to coal phase-out timelines and accelerated retirements in 2023–2024, shrinking the installed base and replacement market. Replacement demand is dwindling and often politically constrained, reducing long-term aftermarket visibility for protection parts. Market share loses strategic value if the pond is drying; Mersen should harvest cash, cut investments and redeploy engineering and sales resources into growth areas like grid batteries and EV charging.
Low‑end surge strips and consumer‑style protectors
Low‑end surge strips and consumer‑style protectors are commoditized, retail‑like SKUs that do not leverage Mersen’s industrial specialty strengths; the global SPD consumer market was ~USD 3.4bn in 2024 with low single‑digit CAGR and heavy price competition. Brand premium is ignored at mass retail and channel costs erode margins, yielding minimal growth and sub‑5% margins. Recommend divestiture or licensing if any exposure remains.
Obsolete motor brush formats for aging equipment
Obsolete motor brush formats for aging equipment in Mersen's 2024 portfolio occupy a declining niche with disappearing fleets, very small volumes, long-tail logistics and poor turns that tie up working capital for marginal revenue; sunsetting is managed via defined last-buy programs to limit exposure.
- legacy SKUs: very low volumes, long tail
- working capital burden: inventory immobilized
- turns: poor, <1% revenue contribution
- mitigation: formal last‑buy/sunset plans 2024
Non‑differentiated cooling plates in high‑competition niches
Dogs: Non‑differentiated cooling plates in high‑competition niches lose margin fast as 2024 OEM procurement trends favor cost over customization; commoditization pushes prices down and engineering CAPEX rarely pays back, leaving Mersen with low share and no moat—a classic cash trap recommending exit. Withdraw and redeploy resources to engineered‑to‑order thermal solutions with higher ASP and recurring service revenue.

- no_moat
- price_erosion_2024
- focus_engineered_to_order
Harvest commodity dogs; free 5-10% WC for grid batteries & EV charging
Commodity dogs (low‑voltage fuses, cooling plates, consumer SPDs, obsolete brushes) show <2% market growth (2024), gross margins <10%, revenue contribution <1–5% and tie up 5–10% working capital; recommend harvest/exit and redeploy to grid batteries/EV charging.
| Metric | 2024 |
|---|---|
| Market growth | <2% |
| SPD market | USD 3.4bn |
| Margins | <10% |
| WC tied | 5–10% |
Question Marks
Hydrogen electrolyzer and fuel‑cell components
Explosive TAM: REPowerEU targets 10 Mt renewable hydrogen and 40 GW electrolyzer capacity in the EU by 2030, and Hydrogen Council estimates a $2.5 trillion hydrogen economy by 2050, but standards and technology winners remain unsettled. Mersen’s graphite and thermal materials align with cell stacks and bipolar plates, yet commercial share is nascent. High cash burn required for qualifications and pilot projects. Bet selectively on partnerships that secure volume and long-term supply contracts.
EV fast‑charging protection and thermal assemblies
EV fast‑charging protection and thermal assemblies sit in Question Marks: public DC fast‑charger deployments grew over 30% y/y in 2024 with wide regional spec divergence, creating demand but fragmented OEM requirements. Mersen has credible protection/thermal IP yet faces fragmented customers and fierce new entrants (ABB, Siemens, ChargePoint expanding vertically). Growth is clear; Mersen’s share is not — prioritize platform deals with top charger OEMs or pivot to adjacent modular assemblies.
5G and data center transient protection
5G rollout requires massive infrastructure build with top-3 RAN vendors (Ericsson, Nokia, Huawei) holding roughly 70–80% market share in 2024, so vendor lists stay tight; global 5G RAN spend remains in the tens of billions annually. Mersen’s surge protection portfolio is a technical fit but incumbents dominate socket-level supply; sales cycles run 12–24 months with heavy engineering. Prioritize lighthouse wins, capture field data, and productize learnings rapidly to scale.
Advanced packaging TIMs and graphite foils
Chiplet and power‑module packaging faces acute thermal-path deficits; in 2024 industry reports highlighted thermal management as a top 3 failure mode for package qualification, so Mersen’s advanced TIMs and graphite foils are technically promising but face arduous validation and crowded supplier competition. A handful of tier‑one design wins would reclassify this Question Mark into a Star; fund application labs and joint testing to accelerate 12–24 month validation cycles.
- Thermal priority: top‑3 failure mode in 2024 reports
- Validation: typical 12–24 month cycle
- Strategy: fund application labs + joint testing
- Upside: a few tier‑one wins → Star in BCG
Battery gigafactory process equipment and fixtures
Gigafactories are sprouting globally with over 200 planned or under construction by 2024; tooling standards remain fluid. Mersen can leverage high‑temperature materials and graphite electrode expertise but lacks a proven battery‑factory playbook. Cash burn is front‑loaded with capex per gigafactory often $1–3B before volumes stabilize. Pilot programs with CATL, LGES or Panasonic can de‑risk for multi‑site rollouts.
- terrain: >200 gigafactories (2024)
- capex: $1–3B per site
- strength: graphite / high‑temp expertise
- risk: unproven playbook, high cash needs
- tactic: pilot with leading cell makers, scale multi‑site
Back winners: partner, pilot, secure multiyear supply in hydrogen, EV fast-charge, 5G, gigafactory
Question Marks: hydrogen, EV fast‑charging, 5G RAN, chiplet thermal and gigafactory tooling — large TAM but fragmented standards and incumbent dominance. 2024 signals: EU H2 target 10 Mt/2030; public DC chargers +30% y/y; top‑3 RAN ≈75% share; >200 gigafactories planned. Strategy: selective partnerships, fund labs/pilots, secure multi‑year supply or platform deals to convert winners into Stars.
| Segment | 2024 metric | Action |
|---|---|---|
| Hydrogen | EU 10 Mt/2030 | Partnerships, qualifying |
| EV DC | +30% y/y deployments | Platform deals |
| 5G RAN | Top‑3 ≈75% share | Lighthouse wins |
| Gigafactories | >200 planned | Pilots with CATL/LGES |
