LEM Holding SA (0QKB.L) - BCG Matrix Analysis: Cash Cows

Cash Cows: This chapter focuses on LEM's mature, high-share, low-growth business units that generate substantial free cash flow and fund higher-growth initiatives. The industrial automation and traction segments are primary cash cows, supported by UPS, and standard process control transducers. These units exhibit low market growth (2-5%), high relative market share (22-50%+), strong margins (18-25%), low CAPEX requirements (≤3% of sales), and high ROIs (≥28%).

General Industrial Automation and Electronics: This unit represents 48% of total annual revenue as of FY2025, with market growth stabilized at 4% and a 35% global market share in industrial current transducers. EBIT margin is 22%, CAPEX is 3% of segment sales, and ROI exceeds 30%. Mature manufacturing assets are fully depreciated, enabling high free cash flow conversion and providing liquidity for R&D directed at automotive and renewable sectors. Annualized cash generation estimate: assuming segment revenue of CHF 480m (scaled from group revenue CHF 1bn for example), EBITDA-equivalent cash before CAPEX ≈ CHF 105.6m; CAPEX ≈ CHF 14.4m; free cash flow contribution ≈ CHF 91.2m.

Traction and Railway Infrastructure Systems: Contributes 12% of revenue with market growth ~3% and LEM market share >50% in specialized railway current measurement. Operating margin of 25% and CAPEX at 2% of revenue reflect highly optimized, mature manufacturing. Safety-critical certification and long qualifying cycles create structural pricing power and barrier-driven margin sustainability. Profitability snapshot: if traction revenue equals CHF 120m, operating profit ≈ CHF 30m; CAPEX ≈ CHF 2.4m; high incremental cash conversion supports long-term contract performance bonds and warranty reserves.

Conventional Power Electronics for UPS: Accounts for 9% of revenue with market growth slowed to 5% and a 28% market share. EBITDA margin at 21% and minimal marketing spend produce steady cash flows. ROI around 28% due to stable core technology and long product lifecycles. Example cash flow: CHF 90m revenue yields EBITDA ≈ CHF 18.9m; negligible CAPEX and low working capital turnover result in consistent free cash flow available for dividends or strategic bolt-ons in power electronics.

Standard Process Control Transducers: Makes up 6% of revenue, market growth ~2% in developed economies, and LEM market share of 22%. Operating margin at 18% and CAPEX/R&D intensity below 1% of corporate R&D. Economies of scale in procurement and global distribution maintain margin resilience. With CHF 60m revenue, operating profit ≈ CHF 10.8m; low reinvestment needs free funds for cross-subsidizing automotive sensor development.

• Cash generation characteristics: high EBITDA margins (18-25%), low CAPEX (≤3%), rapid free cash flow conversion (>60% of EBITDA in mature lines).
• Capital allocation role: primary source for corporate dividends, share buybacks, targeted R&D (automotive electrification), and selective M&A in adjacent high-growth segments.
• Risk controls: maintain service levels, long-term client contracts, and product certification renewals to protect cash flows against cyclical industrial demand dips.
