Nexans is one of the world's three largest cable manufacturers — producing high-voltage subsea cables, terrestrial power cables, telecom cables and industrial cables from copper and aluminium conductors. Listed on Euronext Paris, Nexans is the most direct equity expression of the intersection between LME copper prices (which determine raw material costs and, partly, selling prices) and the energy transition capex cycle (which drives demand for offshore wind cables and grid interconnectors).
Subsea HV Cable: The Crown Jewel
Nexans's high-voltage subsea cable division — laying interconnectors between countries and connecting offshore wind farms to onshore grids — is the company's highest-margin, fastest-growing segment. Nexans's cable-laying vessel Nexans Aurora and its Aurora successors are essential infrastructure for the North Sea offshore wind build-out. The European offshore wind pipeline (hundreds of gigawatts planned through 2030) creates a decade-long order backlog for subsea cable installation.
LME Copper: The Raw Material Cycle
Copper conductors represent approximately 40–50% of Nexans's raw material costs. Nexans typically passes copper price changes through to customers via indexation clauses, but timing differences (buying copper before selling cable) create short-term earnings volatility. At high copper prices, Nexans's working capital requirements increase significantly. The LME copper price is therefore both a cost signal and a demand signal — high copper often correlates with strong industrial and construction activity that drives cable demand.
Grid Investment: The Structural Demand Driver
European grid investment is accelerating dramatically — driven by the need to integrate renewable energy, electrify transport and industry, and reinforce cross-border interconnection capacity. Nexans benefits from national grid operators' multi-decade investment programmes: Elia (Belgium), National Grid (UK), RTE (France) and TenneT (Netherlands) are all major customers with long-term framework agreements. Grid investment is largely policy-driven and relatively recession-resistant.
Telecom & Data: The Digital Infrastructure Link
Nexans produces optical fibre cables and copper data cables for telecom networks and data centres. Hyperscaler data centre build-out and national broadband roll-out programmes create structural demand growth in this segment. Telecom cables are less cyclical than power cables, providing earnings diversification from the construction and energy cycles.
Key Risks
Nexans's subsea cable installation capacity is constrained by vessel availability — any vessel downtime creates revenue delays and contractual penalty risk. Copper price volatility creates working capital and margin timing complexity. Competition from Prysmian (Italy) and NKT (Denmark) is intense in the high-voltage cable market. Offshore wind project delays — permitting, grid connection approvals — can push cable installation revenues into future periods.
