Other electrical equipment and component manufacturing

A residual group holding batteries, wire and cable, wiring devices and a tail of unlike electrical components. The screen takes the one niche with a clean public anchor — building wire and cable — and says plainly that the rest was not examined. The attraction is the same electrification demand that lifts the rest of subsector 335: every data centre, house and grid upgrade is wired with this product, and it is heavy enough that domestic mills hold the market. The anchor shows what holding it takes. In 2024 Prysmian bought Encore Wire for $290.00 a share, an implied enterprise value of about €3.9B — 8.2× 2023 EBITDA [A]. Encore made about $2.6B of revenue and $517M of EBITDA in 2023 from a single vertically integrated campus in McKinney, Texas, which Prysmian's release describes as built for low-cost production and centralised distribution [A]. That is the mechanism: building wire is a copper-conversion business in which the metal is most of the selling price, the product is a certified commodity that electrical distributors buy on price and fill rate, and the winner is whoever draws its own rod, carries the copper inventory and ships a full truck next day. A small mill buys rod at a worse price, carries the same metal exposure on a thinner balance sheet, and sells to distributors who already have two suppliers. The world's largest cable maker chose to buy that position rather than build it. The 207 Canadian establishments under five people are doing something else — harnesses, battery packs, specialty assemblies — and each would need its own record.

The gigafactory wave is real demand, not hype: CATL alone sold 661 GWh of lithium-ion batteries in 2025, up 39% [A], and North America is trying to localise that supply. But a cell plant is not a business an entrant with ordinary resources can go into. It is a few cell makers building plants that cost billions, sized for an anchor automaker, and underwritten by production subsidies about as large as the capex. PowerCo's St. Thomas plant is up to C$7B for up to 90 GWh [A] — about C$78M per GWh at the stated maximums — and the Parliamentary Budget Officer puts the federal and Ontario production subsidy for that one plant at C$13.2B [A]. The US 45X credit pays $35 per kWh of cells sold until 2030 and phases out by 2033 [A]. Everything is sunk years before the first sale, and the pipeline shows what happens when the demand forecast moves. Québec wrote off $270M when it ended Northvolt Six [A]; Honda indefinitely suspended its C$15B Ontario EV value chain [A]; Ford took a $2.9B charge leaving BlueOval SK, taking two Kentucky plants at a $0.9B fair value while assuming a $3.8B DOE note [A]; GM booked $7.9B of EV realignment charges in 2025, battery-cell JV settlements included [A]. Even the leader in Canada earns on the subsidy: LGES's Q3 2026 operating profit of KRW 756B falls to KRW 339.1B without North American credits [B]. Plants are surviving by pivoting to grid and data-centre storage — NextStar Windsor now sells ESS cells, and Tesla shipped its first Megapack with Nevada-made LFP cells [A]. The reachable business is around the plant, not in it: construction (EllisDon expects about 1,300 workers at peak in St. Thomas [A]) and the suppliers and services a town of 42,840 people [A] will be asked to provide.
