Market cap, ratios, CAGR and revenue: company table snapshot as of 30 Oct 2026 (the same figures on every page). Price: snapshot as of 30 Oct 2026. Not investment advice.
Where it fits
Steps grid power down to usable voltages and distributes it safely across the facility - the first stop for incoming electricity before it reaches any other system.
Why it matters
Every watt the data centre uses passes through this layer first; undersized or unreliable transformer capacity caps the whole site's growth.
Where the value pool sits
Transformer and switchgear makers sell large-ticket equipment with long replacement cycles, plus substation/interconnect project revenue as campuses scale.
Key drivers
New campus and capacity buildout
Grid-connection upgrades for larger power draws
Renewable/PPA interconnection projects
Potential bottlenecks
Grid interconnection approvals and timelines
Transformer manufacturing lead times during a capex upcycle
Copper/core-steel input cost volatility
