Triton shops Trench, the grid maker Siemens sold at the bottom for a fraction of its order book

The exit door is open

Trench Group, the Berlin-based maker of high-voltage bushings and instrument transformers, is going on the block ². Its parts sit inside every major substation connecting AI data centers to the grid, by the account of 23 September 2026 ². Triton Partners has retained Morgan Stanley to run a sale and an IPO in parallel ¹².

The potential valuation runs to several billion euros, with a deal possible as early as 2027 ². The mandate extends a relationship: Morgan Stanley led the lenders behind Trench's €1.4 billion term loan in July 2026 ². No party has confirmed the process, which traces to a single Bloomberg account↗ carried that day by two outlets ¹². The people cited call the deliberations early and no deal certain ².

Two years, one re-rating

Siemens Energy agreed to sell Trench in October 2023↗ while forecasting a €4.5 billion net loss for the year on quality failures at its wind unit, Siemens Gamesa ⁶⁷. The buyer was Triton's Fund V, and the deal closed in April 2024 ²⁶. Neither party disclosed the price for a business with about 2,400 staff across nine factories; sources put it in the mid-triple-digit millions of euros, roughly €400 to €600 million ¹⁶.

Since then revenue rose 33% to €906.5 million in calendar 2025, by Crypto Briefing↗'s figures ¹. The company says annual revenue has doubled since independence to more than $1.1 billion, a 30 July 2026 statement↗ of current scale, not the calendar-2025 count ³. The order book tops €2.1 billion, roughly twice annual sales ²; Crypto Briefing's tally was nearer €1.8 billion ¹. North America took around half of first-half 2026 order intake, up almost 400% since 2024 ³.

Buyers pay for time

The premium shows one link down the chain. On 2 September 2026, Vertiv agreed to pay about $1.45 billion up front, up to $2.6 billion with earnouts, for UtilityInnovation Group ⁴⁵. The microgrid firm, founded in 2020, priced near 13 times expected 2027 EBITDA ⁴. Vertiv's chief executive frames the logic: advantage depends on "how quickly they can move from site selection to first token" ⁴⁵.

Trench's own scarcity explains the pricing. Chief executive Bahadir Basdere says bushing lead times now run up to two years ². On 30 July 2026 the company opened its first US factory, a Charlotte plant costing more than $60 million and built for dry-type bushings up to 765 kV ³.

Who pays, who collects

Whoever wins Trench, a strategic or the IPO book, pays the AI-scarcity top, and Triton's Fund V investors collect the spread on a bottom-of-cycle carve-out ². Siemens Energy sold the bottleneck; Triton is selling the queue. The tell arrives in 2027: a fat strategic bid shelves the listing, a thin one sends Trench public ¹².
