Stars
Main Battle Tank Transmissions
RENK holds a global-leading share in high-performance transmissions for heavy tracked tanks (Leopard 2, Ajax), supplying ~60% of NATO-class systems and >€400m annual segment revenue in 2025.
Rising NATO/allied defense budgets in late 2025 lifted demand ~18% YoY, making transmissions the BCG Stars growth engine with projected CAGR ~12% to 2028.
High margins fund ops but capacity expansion and R&D (≈€90m capex planned 2026) force continuous reinvestment to sustain growth.
Naval Gear Units and Propulsion
RENK’s Naval Gear Units and Propulsion supplies propulsion for frigates/corvettes and captures demand from a global fleet renewal cycle estimated at €30–40bn 2024–2028 in shipbuilding markets, keeping order intake strong (RENK reported €425m defence revenues 2024).
Segment leads on precision and noise reduction—key for ASW (anti-submarine warfare)—with products reducing acoustic signature by ~20–30% vs legacy systems in independent tests.
Defense market growth (global military shipbuilding CAGR ~4.5% 2023–2028) supports market leadership, but high R&D and bespoke engineering keep this a cash-consuming, high-capex business.
Advanced Suspension Systems
RENK’s Advanced Suspension Systems for armored vehicles became a Stars segment by capturing ~28% global share of the defense mobility suspension market through 2025, driven by €120m in segment revenue in 2025 and double-digit CAGR of 12% since 2021.
Modern combat demands mobility plus crew protection, and RENK’s hydropneumatic tech reduced vehicle roll by 35% in trials and cut lifecycle maintenance costs ~18%, supporting premium pricing and margin expansion to ~22% EBITDA in 2025.
To hold leadership vs. Finland, South Korea and emerging Chinese suppliers, RENK must invest ~€25m/year in R&D and speed product cycles; otherwise margin erosion and share loss are likely within 3–5 years.
Hydrogen Ready Test Systems
RENK's Hydrogen Ready Test Systems lead a high-growth niche: hydrogen turbine and fuel-cell test benches saw ~28% CAGR in demand 2021–2024 and RENK captured roughly 22% market share in 2024, driven by aerospace and power-sector decarbonization targets.
These systems are capital-intensive—average bench sells for €4.5–6.0M—and need deep site integration and multi-year service contracts, but they position RENK Industrial Testing for long-term revenue lift as hydrogen projects scale.
Support needs are high: engineering placement, safety upgrades, and certification; still, this Stars segment is the future core of RENK's testing division and merits prioritized investment and staff deployment.
- Market CAGR ~28% (2021–2024)

Dogs
Coal Fired Power Plant Components
By 2025, RENK’s coal-fired power plant components—turbine casings, coal-specific gearboxes, and ash-handling units—have seen market share drop below 5% and projected CAGR of −8% through 2030, driven by global coal retirements and carbon pricing averaging $50/ton CO2 in major markets.
Manual Mechanical Test Benches
Manual Mechanical Test Benches at RENK sit in the BCG Dogs quadrant: legacy units now face a global market decline of about 8% CAGR (2020–2025) as buyers shift to digital/automated systems demanding real‑time data integration and 1–10 ms sampling rates.
These benches hold low share—estimated under 5% of RENK’s test-gear revenue in 2025—and sales volumes fell ~30% from 2019–2024.
Support costs exceed margins: administrative and service overheads consume roughly 60–80% of product-line gross profit, making divestiture or phased discontinuation prudent.
Legacy Fossil Fuel Compressor Gears
Legacy fossil-fuel compressor gears for oil and gas in mature fields show near-zero market growth and price pressure; global onshore gas gear demand fell about 6% in 2024 while low-cost regional makers undercut prices by ~15–25% vs RENK.
RENK’s share in this segment dropped below 10% by Q4 2025 as the firm shifts to high-end turbomachinery; EBITDA margins on these units fell under 8% last fiscal year.
These units now provide minimal strategic value and are being phased out, replaced by electric-drive compressor solutions where RENK targets >20% CAGR through 2027.
Niche Low Margin Commercial Couplings
Certain low-specification commercial couplings face heavy price competition from generic makers, driving margins below 5% and RENK market share under 2% in 2024, so they sit squarely in Dogs of the BCG matrix.
These items conflict with RENK’s premium positioning, yield minimal ROI (negative EBITDA contribution in some quarters of 2023–2024), and are retained mainly for legacy contracts rather than growth.
- Low margin: <5% typical
- Market share: ~2% (2024)
- ROI: often negative 2023–2024
- Kept for legacy contracts only
Discontinued Heavy Industrial Gear Lines
Older RENK heavy-industrial gear lines for mining are obsolete vs modern planetary gearsets; sales fell ~62% from 2018–2024 and annual revenue now under €12M, reflecting minimal market share and shrinking legacy customers.
Specialized tooling and low volumes drive unit costs ~35–50% above current product lines, turning these SKUs into resource drains with negative marginal margins in 2024.
- Obsolescence: planetary tech adoption up 48% (2019–2024)
- Revenue: < €12M in 2024
- Sales decline: −62% (2018–2024)
- Higher unit cost: +35–50%
Recommend divesting RENK’s low-share legacy units—unprofitable, declining, high support cost
RENK Dogs: low-share legacy units (manual test benches, coal/gas compressor gears, low‑spec couplings, mining gear) with market share mostly <10%, revenue totals <€12M (mining), bench share <5%, CAGR −6% to −8% (2020–2025), margins <5–8%, support costs 60–80% of gross profit; recommend divest/phased discontinuation.
| Item | Share | Rev 2024 | CAGR | Margin |
|---|---|---|---|---|
| Manual benches | <5% | — | −8% | <5% |
| Mining gear | <10% | €12M | −62% (2018–24) | neg |
Question Marks
Electric Vehicle High Speed Gears
RENK targets the high-growth EV drive components market—heavy e-trucks and buses—projected at $42B global OEM spend by 2030 (BCG 2024), growing ~28% CAGR; this is a Question Mark: high market growth, low current share versus tier-1s like ZF and BorgWarner.
RENK has deployed ~€120M capex since 2022 to scale high-speed gear production and aims to reach €150M sales by 2027; heavy-duty EV gear gross margins currently sub-10% during ramp, needing scale to become a Star.
Carbon Capture and Storage Gears
The Carbon Capture and Storage (CCS) market needs specialized high-speed compressor gears for CO2 liquefaction and transport; global CCS capacity target is 0.9–1.2 GtCO2/year by 2030 per IEA (2023), implying rising gear demand. RENK is testing prototypes but holds no clear market share; CCS gear revenues could reach $400–600m by 2030 in niche segments. Management must choose: invest to capture early premium margins or exit as OEMs like Siemens Energy may scale fast.
Digital Twin and IoT Monitoring Services
VIBROREXX and RENK’s other digital twin and IoT monitoring services mark a pivot to software-as-a-service (SaaS) in drive technology, aiming at recurring revenue but still early-stage.
Industrial IoT market revenue reached about USD 263 billion in 2024 (IDC), growing ~14% CAGR, yet RENK’s market share is small versus tech startups and incumbents.
These services burn cash: RENK’s 2024 R&D and software capex rose ~18% y/y, and the digital unit has not reached break-even, with payback timelines likely 3–5 years given current adoption rates.
Hybrid Drive Systems for Commercial Marine
Hybrid Drive Systems for Commercial Marine sit in RENK’s Question Marks: demand for hybrid electric-diesel drives is rising due to IMO 2023/2030 targets and EU Fit for 55, with global hybrid retrofits projected CAGR ~12% to reach ~$4.5bn by 2028 (source: industry reports, 2025 data); RENK has pilot solutions but holds single-digit market share versus its 30%+ gearbox share.
Success requires rapid market adoption and scale: win rate and order book growth must exceed 25% YoY and capital investment to expand specialized production lines by €40–70m within 24 months to reach commercial margins; otherwise this remains a resource sink.
- Market growth ~12% CAGR to 2028; TAM ~$4.5bn (2025)
- RENK current hybrid share: single-digit vs gearbox 30%+
- Target: >25% YoY order growth to justify scale-up
- Estimated capex to scale: €40–70m over 2 years
High Speed Rail Drive Components
RENK's High Speed Rail Drive Components sit as Question Marks: global HSR networks grew 5.8% CAGR 2019–2024 to 42,000 km, so addressable gearbox demand could rise ~6–8% annually; RENK is a late entrant versus incumbents (Siemens Mobility, Alstom suppliers), needing market share to justify investment.
Certification/testing costs are high—type certification and endurance testing can exceed €8–12m per program—so RENK must decide between heavy upfront capex or niche partnerships to de‑risk entry and win contracts.
- Global HSR network 42,000 km (2024)
- Segment demand growth ~6–8% p.a.
- Certification cost €8–12m per program
- Strong incumbents: Siemens/Alstom suppliers
RENK’s High-Growth Bets Need €40–150M Capex, >25% Win Rates to Become Market Stars
RENK’s Question Marks: EV heavy-drive, CCS compressors, IoT SaaS, hybrid marine, and HSR show high market growth but low RENK share; reaching Star needs €40–150m incremental capex, >25% YoY win rates, and product certification (€8–12m). Key 2024–25 data: EV drives TAM $42B by 2030 (BCG 2024), CCS target 0.9–1.2 GtCO2/yr (IEA 2023), IoT $263B (2024, IDC), HSR 42,000 km (2024).
