Peterson Partners announced on September 9 that it has closed a $510 million capital raise for Peterson Kelso Coinvest, LP, a single-asset continuation vehicle for Kelso Industries, a Fund VIII and Fund X portfolio company. NorthSands Capital was the sole lead investor and committed more than $450 million. As part of the transaction, Peterson Partners Fund X rolled its position and made an additional investment in Kelso.
The asset.
Kelso Industries was founded in 2021 through Peterson’s partnership with Steve Carroll and Steve Nicholson. Headquartered in Draper, Utah, the company delivers mechanical, electrical, and plumbing (MEP) services to commercial, institutional, and industrial customers across more than 40 states with more than 4,000 employees. End markets named in the release include data centers, healthcare, airports, industrial facilities, advanced manufacturing, and other mission-critical commercial environments. Kelso’s partnership-oriented model is built to preserve local culture, customer relationships, and operating autonomy under a national platform — the same playbook behind recent bolt-ons covered on Insights, including three contractors added in Alabama, Wyoming, and Washington.
The structure.
This is a single-asset continuation vehicle, not a sale to a new sponsor that takes Peterson fully out. Peterson Kelso Coinvest, LP holds the company; NorthSands leads the new money at more than $450 million of the $510 million raise; and Peterson Fund X — the firm’s current flagship — rolls its existing stake and puts in additional capital. Proceeds are earmarked for continued growth: strategic acquisitions, investment in people and capabilities, and expansion into new markets and business opportunities.

Why a continuation vehicle matters for MEP platforms.
In trades roll-ups, the usual liquidity path is a full sale to another sponsor or a strategic. A continuation vehicle is different: the sponsor keeps a meaningful piece (here, Fund X rolls and adds), a CV specialist underwrites a large new check (NorthSands, founded in 2023 by former Blackstone SMD Bruce McEvoy and focused on single-asset CVs), and the operating company gets another multi-year runway for M&A without resetting the partnership model sellers already bought into.
For an MEP platform that has been acquiring under a culture-preserving partnership structure, that continuity matters. Selling owners who rolled equity into Kelso stay in a vehicle still sponsored by the firm that backed the platform from founding — with fresh dry powder aimed at more of the same: acquisitions, people, and markets.
What it means.
For commercial and industrial MEP owners, three practical points.
First, this is not an exit announcement dressed as growth capital. Peterson stays in. NorthSands leads new capital. The disclosed use of proceeds is more buy-and-build, not a wind-down.
Second, single-asset continuation vehicles are now a live capital path for scaled MEP platforms — alongside traditional sponsor-to-sponsor sales and public strategics. When a platform is large enough that Fund VIII wants liquidity and Fund X still wants exposure, a CV is how both get solved in one close.
Third, the buyer profile for the next wave of MEP add-ons just got better funded. A $510 million vehicle with a >$450 million sole lead, explicit M&A mandate, and sponsors still in the capital structure is a platform still shopping — on the same partnership model Kelso has used since 2021.
No enterprise value, EBITDA, or purchase multiple was disclosed.
