GE Vernova Pays $9 Billion for a 5% Part That Gates the Grid

$9 billion for a part that makes up 5% to 8% of a transformer's bill of materials.

That is the price GE Vernova agreed to pay for Trench Group, signed on 28 October 2026. The $9.0 billion in dollar equivalents splits evenly between cash and debt and lands at 13 times Trench's forecast 2028 adjusted EBITDA before synergies.

Trench is not a turbine builder. The Berlin company makes bushings, cable terminations, instrument transformers and coils — the hardware that carries high-voltage current into and out of a transformer without arcing through its insulation. GE Vernova expects the deal to close in late 2027, pending regulatory approval and employee consultation.

What $9 billion actually buys

The asset is older and larger than the price suggests. Trench has more than 130 years of engineering history, 3,000-plus employees and 11 factories across eight countries. It supplies more than 800 utilities and hyperscalers, and its components appear in the majority of high-voltage direct-current lines built worldwide, according to GE Vernova.

Revenue runs at an estimated $1.4 billion this year and is forecast at $1.9 billion in 2028, at roughly 36% adjusted EBITDA margin. The company carries about $5 billion in backlog and framework agreements. Around half of that sits in some 80 framework agreements, several reaching into the 2030s.

Triton carved Trench out in April 2024. Since then the business has doubled annual revenue past €1 billion. That is a fast re-rating for a supplier of bushings and coils, and it explains why the exit landed at a strategic buyer instead of a second sponsor.

Goldman Sachs and UBS advised GE Vernova; Skadden handled legal work. Bank of America and Morgan Stanley advised Triton. That advisory bench is the one you hire for a transaction that has to clear two continents of regulators.

GE Vernova puts the global high-voltage equipment market at roughly $90 billion in 2025, growing about 8% a year to $130 billion by 2030. North American demand is forecast to grow faster, near 9% annually. Those are company estimates, not audited figures, and they carry the usual optimism of a seller describing its own market.

The 5% to 8% that gates the transformer

Bushings are cheap next to the machine they protect. Strazik put them at 5% to 8% of a transformer's bill of materials during the 28 October earnings call. A small share, and a hard stop when it is missing.

Large-transformer buyers often name the bushing maker in the specification. That detail decides who can ship. Trench rates its transformer bushings to 1,200 kV and other products to 800 kV, which puts it in the small group qualified for the highest-voltage work.

The component sits on the boundary between the grid and the equipment. It routes current through the tank wall, holds the voltage off the steel, and takes the thermal and mechanical load of a line that may run for decades. Get the interface wrong and the failure is not gradual.

This gives us a lot more control over the critical technology in the supply chain to meet the growing backlog that we see with differentiated technology.— Scott Strazik, CEO, GE Vernova

GE Vernova already buys most of its transformer bushings from outside suppliers. After the deal closes, it expects to pull a larger share into Trench factories. The shift will be gradual, because qualification and customer specifications move slowly.

Vertical integration here is about schedule control. A late bushing holds a finished transformer in the yard. A held transformer holds a substation, and a held substation holds the load behind it.

Why the bottleneck moved downstream

The demand side is not subtle. GE Vernova's Electrification backlog reached $46.1 billion in the third quarter, up 55% from a year earlier and from roughly $7 billion at the start of 2022, Strazik said.

Companywide backlog hit $196.7 billion, against $135.3 billion a year earlier. Orders came in at $29.3 billion, up 96% organically. Revenue rose 27% to $12.6 billion, and free cash flow reached $5.4 billion.

Gas turbines tell the same story with a twist. Capacity under contract reached 122 GW, from 116 GW in the prior quarter. The quarterly gain was 6 GW. GE Vernova still expects at least 130 GW by year-end.

The scarce input has moved downstream, from the turbine to the substation. That shift is why a company with $16.8 billion of cash and an A- rating from Fitch spends $9 billion on a component supplier instead of another generation asset.

It also explains why grid rules now read like equipment specifications. As we wrote in October, ERCOT's grid-forming requirement turned a technical preference into a procurement line item — the same logic of buying certainty rather than capacity.

The transformer business is an oligopoly with long memories. Hitachi Energy, Siemens Energy, ABB and GE Vernova dominate large power transformers and the switchgear around them. Each has announced North American capacity, with most new lines starting after 2027.

The Charlotte arithmetic

Trench's only U.S. plant opened in Charlotte, North Carolina. Production of bushings rated to 765 kV is due to start in late 2027, the same window as the acquisition close.

Initial output is set at up to 3,500 bushings a year, with room to reach 10,000. That is the first U.S. source of 765 kV bushings, Strazik said, which matters for a build-out that keeps running into import schedules.

There is room to more than double production capacity from the initially planned 3,500 to 10,000 bushings per year, reflecting Trench Group's commitment to the growing North American market.— Ulrich Künster, VP Communications, Trench Group

The timing is awkward and useful at once. The plant ramps as the deal closes, so the capacity arrives just as GE Vernova takes control of the order book that fills it.

The projects waiting on the part

The abstract bottleneck has addresses. In northeastern Kentucky, American Electric Power subsidiary Kentucky Power plans a new 765 kV substation and two 765 kV transmission lines to connect TeraWulf's planned 1 GW Muskie Data Campus to the regional grid. Substation construction is scheduled to begin in February 2027, with line work later that year.

That schedule is why bushings matter. A 765 kV substation needs bushings rated for the voltage, and the qualifying suppliers are few. If the hardware slips, the campus waits. The data halls do not care about the grid queue. The grid queue does not care about the data halls.

The mismatch is structural. ENR reported in May that interconnection timelines in some regions have stretched to five or six years or longer, while hyperscale data centers can be built in roughly two to two and a half years. The gap between those two clocks is where equipment scarcity turns into rent.

GE Vernova's equipment backlog reached $42.2 billion, up 60% year over year, including $5 billion from Prolec GE. Orders of $29.3 billion in the quarter were up 96% organically. Customers are not waiting for a price signal to order. They are ordering to hold a place in line.

Bushings are a small line in that budget and a large line in the schedule. That asymmetry is the whole investment case, and it is also the risk: if the queue clears faster than expected, the premium for a guaranteed slot fades.

For Trench, the customer list cuts both ways. More than 800 utilities and hyperscalers depend on its components, which makes the backlog sticky. That list also includes rivals of GE Vernova, which makes the integration delicate.

The counter-case

Thirteen times 2028 EBITDA is a full price for a component maker. It assumes the 36% margin holds and the $5 billion backlog converts. Close in late 2027 leaves more than a year for regulators and works councils to slow the timetable.

The demand picture has a soft edge. Gas capacity under contract grew 6 GW in the quarter. A large part of that book is slot reservations rather than firm orders, and reservations can be released if data-center plans slip.

Strazik described 2027 as solid growth, "if not at the breakneck pace of the first half of 2026." That is a careful sentence from a chief executive who has watched order growth decelerate.

Integration adds its own friction. Eleven factories in eight countries, three thousand employees, and a customer base that chose Trench partly because it was independent of GE Vernova. Rivals that buy bushings from Trench will now be buying from a competitor.

What to watch before close

Three checkpoints decide whether the price was right. Regulatory clearance in Europe and the United States, with employee consultation attached. The Charlotte line actually producing 765 kV bushings in late 2027. And the share of GE Vernova's bushings sourced internally, the number that turns vertical integration into margin.

A fourth matters for the sector. If Electrification margin holds near 19% while backlog keeps growing, the bottleneck is durable and the multiple is defensible. If orders slow and reservations unwind, GE Vernova will have bought capacity at the top of the cycle.

The deal is a clean test of a larger claim: that the next decade of energy infrastructure will be won on delivery, not on generation. Nine billion dollars says the constraint is a bushing.
