Given low share, weak margins, and >€5m annual capex-to-revenue drag, these lines are prime divestiture candidates to refocus on LEM’s industrial power-sensor strengths.
Standardized Shunt Resistors
Standardized shunt resistors sit in Dogs: low-growth, low-share; LEM’s magnetic tech gives no edge and market growth is ~1% CAGR (2020–2025) while specialized resistor makers hold >60% share; LEM’s shunts generate near-break-even margins (≈1–2% operating margin in 2024) and tie up ~€5–10m working capital that could fund higher-return Stars or Question Marks.
Regional Niche Industrial Meters
Certain localized, non-standard measurement devices designed for specific geographic markets have failed to scale globally; these regional niche industrial meters show annual revenue declines of 6–12% and account for under 3% of LEM’s 2025 sales (LEM Group revenue ~CHF 320m in 2024). They face low growth and low market share due to outdated technical specs and regulatory fragmentation. LEM treats them as legacy obligations and minimizes capex and R&D here.
- Low growth: -6–12% CAGR
- Low share: <3% of 2025 sales
- Minimal capex and R&D allocation
- High maintenance cost, limited resale value
Basic Isolated Amplifiers
LEM’s Basic Isolated Amplifiers compete with large semiconductor firms and hold negligible share (below 1% globally in 2025), in a mature, low-growth market with ~2% CAGR; they add little to LEM’s high-precision measurement strategy and are excluded from new strategic plans.
- Market share <1% (2025)

If technical milestones hit and SiC adoption reaches projected 40–50% of EV/inverter markets by 2028, these products could move from Question Marks to Stars, driving double-digit revenue growth for LEM.
Energy Harvesting Wireless Sensors
As a Question Mark in the BCG matrix, LEM’s self-powered wireless current sensors target an Industry 4.0 IoT market growing at ~22% CAGR (2024–30) with global industrial IoT spending of $200B in 2025; LEM is a new entrant with estimated <2% share versus startups and incumbents.
LEM must choose: invest — ~€15–25M over 3 years for global sales, channels, and certification to reach 10–15% share in select segments, or exit if pilot adoption stays <8% after 24 months, given expected payback risks and coalition costs.
Residential Energy Management Systems
LEM’s Residential Energy Management Systems sit in the Question Marks quadrant: rising prosumer adoption—global residential solar+storage installations grew 28% in 2024 to ~7.2 GW—drives high market potential for home energy monitors tied to EV charging.
LEM launched consumer-facing monitors in 2024 but holds under 3% share versus >25% for top home-automation incumbents, so revenue is small while unit economics lag.
Customer acquisition and software integration swallowed ~€9.6M in 2024 capex/Opex, pressuring cash until scale or partnerships improve margins.
- High growth: residential solar+storage +28% (2024)
- LEM share <3% vs leaders >25%
- 2024 cash burn on category ≈ €9.6M
Aviation Electrification Solutions
eVTOL aircraft are a high-growth, high-risk segment for LEM’s high-reliability current sensors; global eVTOL orders reached ~2,100 vehicles by end-2024 and BloombergNEF projects a $2.7B component market by 2035.
LEM has prototypes in testing but holds minimal market share as OEMs face FAA/EASA certification timelines through 2026–2030; meaningful revenue likely requires multi-year investment and qualification cycles.
These offerings are strategic long-term bets: high R&D and certification costs, potential high margins if adopted widely, but delayed payback and concentration risk.
- Orders: ~2,100 eVTOLs (end-2024)
