GE Vernova’s $9bn Trench deal buys four times its grid parts output as TPG eyes Ark

Trench makes about four times the bushings, instrument transformers and coils that GE Vernova makes itself, and its own cash flow covers the interest on the debt that funds half the price. TPG's $5bn Ark talks buy an owner that must keep building.

GE Vernova is buying capacity it cannot build fast enough. Trench Group expects $1.4bn of 2026 revenue from bushings, instrument transformers and coils. GE Vernova makes about $0.3bn of the same three products, per slide 6 of its presentation.

That is more than four to one, and Trench is about four fifths of the combined output. The slide says the deal "vertically integrates an existing supplier; increases capacity for key grid equipment". The price is $9bn, and this ratio is not in the press release.

GE Vernova said on Wednesday it will pay that sum for Trench, which makes high voltage components that connect grids and measure their performance. The same morning the FT reported that TPG is in talks to buy Ark Data Centres, a UK group, from Elliott for about $5bn. The deals buy grid components and data centre buildings, respectively.

A bushing is an insulated pass through that carries current into a transformer. An instrument transformer steps high voltage down for metering and protection. Trench serves more than 800 utilities and hyperscalers. Per the press release, its components are present in the majority of high voltage direct current lines built globally.

The price and debt costs

GE Vernova pays EUR 8.0bn, or $9.0bn at its 1.12 rate. That is 13 times Trench's 2028 adjusted EBITDA of $0.7bn, before synergies. The 10-Q calls it a fixed purchase price.

GE Vernova expects to fund half with cash and half with debt, about $4.5bn of each. Interest should run near $0.2bn a year. Trench's forecast free cash flow is $0.3bn in 2027 and $0.4bn in 2028, so a full year of interest is covered about 1.5 times, then 2 times.

Trench can therefore cover its debt costs before any savings from combining the businesses. GE Vernova held $16.8bn of cash at 30 September, so the $4.5bn cash leg is 27 percent of it. The group says debt will stay below one times EBITDA. Closing is expected in late 2027, so the risk is delivering capacity, not paying interest.

Margin and backlog support the price. Trench forecasts an adjusted EBITDA margin of about 33 percent for 2026 and 36 percent for 2028, on its own accounting policies. GE Vernova's Electrification segment earned 18.5 percent over the first nine months. Backlog and framework agreements of about $5bn equal 3.6 times 2026 revenue, and CEO Strazik says some "reach into the next decade".

With the $50 million to $100 million of cost synergies targeted by 2030, the multiple falls to 11 to 12 times.

Valuation and execution risks

The valuation is the main concern. Thirteen times a 2028 number, with a close in late 2027, is rich at the top of the grid cycle. GE Vernova paid $5.2bn in cash in February for the other half of Prolec GE, a precedent for buying Electrification capacity.

Margin and cash flow support the valuation. Trench forecasts a higher margin than the segment, and the debt costs $0.2bn against $0.3bn to $0.4bn of cash. Triton, the seller, says Trench passed EUR 2bn of order intake and EUR 1bn of revenue under its ownership.

The buyer also inherits a capital programme. GE Vernova says it expects to grow output through incremental capex. Trench's Charlotte plant for 765kV equipment is expected to begin production in late 2027.

Two terms add risk. Each 0.01 move in EUR/USD shifts the dollar price by about $80m. GE Vernova has agreed to pay a termination fee if regulatory approvals are not obtained within specified timeframes. It would be paid no earlier than the second half of 2027.

Orders do not signal weak demand. Electrification orders fell 9 percent organically in the third quarter against large synchronous condenser orders a year earlier. Book to bill was about 1.4, and Electrification backlog rose 55 percent to $46.1bn.

What TPG would buy at Ark

Ark is a different kind of purchase. The FT says the talks value Ark at about $5bn and a deal is not guaranteed. It would rank among the top five global data centre deals this year. Ark runs 27 centres across the UK and Belgium.

Data centre deals worth $89.4bn have been struck this year, 50 percent more than in all of 2025.

The accounts of the operating company, Ark Data Centres Limited, lead with income. In the year to June 2025 it booked data centre income of GBP 133m, up 21 percent. Power recharged came to GBP 67m and fit out fees to GBP 24m.

The campuses sit in separate property companies. At 30 June 2025 they held 108 MW of built capacity, with 14 MW under construction. The accounts also name Union Park, Longcross Park and Alliance Park as further sites to build out.

Dividing $5bn by 108 MW gives $46m per built megawatt. That is a ceiling, because the $5bn covers all 27 centres and any capacity built since June 2025. Companies House also shows a CBRE Loan Services charge created on 1 April 2026. A Lloyds Bank charge from March 2022 was satisfied on 8 June 2026.

The seller's price has moved. Reuters reported in September 2025 that Elliott was exploring a sale that could fetch more than GBP 3bn, or $4.00bn. Offers in 2023 had fallen short of expectations. Five billion dollars is up to 25 percent more in 13 months.

Ark's joint venture with the Cabinet Office, Crown Hosting Data Centres, gives it access to UK public sector requirements. TPG would pay about $5bn for an owner with that access and three more campuses to build out.

The next earnings test

GE Vernova reports fourth quarter results on 27 January 2027. Its Electrification guide implies $4.0bn to $4.5bn of revenue, against $3.86bn in the third quarter. The segment guide is 18% to 20% for the year, trending toward the higher end. That leaves fourth quarter segment EBITDA of roughly $0.7bn to $1.1bn. A fourth quarter margin below the 18.5 percent nine month level would put the top of that range out of reach.
