Introduction
A regulated utility earning a little under 10% on its equity makes a poor leveraged buyout and a natural infrastructure investment. A regulator caps the upside, but the asset offers a regulated return that is close to certain and grows with approved investment, the mechanism explained in the energy guide's article on rate base and allowed ROE, and that is what an infrastructure fund underwrites. When Canada Pension Plan Investment Board (CPP Investments) and Global Infrastructure Partners (GIP) bought ALLETE, the Minnesota utility group, they accepted a cut in its main utility's allowed return on equity (ROE) to 9.65% from 9.78% to win approval. Infrastructure funds buy with lower target returns, longer holds and asset-level debt, often taking a minority slice rather than a company, which changes the mandates, the financing and the clock a coverage banker works to.
Core, Core-Plus and Value-Add: Where the Return Targets Sit
Infrastructure managers sort their strategies into risk bands, and the band predicts what a client will pay and how long it will hold. Mercer's primer on private markets infrastructure investing sets out four, with net internal rate of return (IRR) targets drawn from what managers state:
| Risk profile | Typical assets | Manager net IRR target | Holding period |
|---|---|---|---|
| Core | Utilities, contracted power, mature airports | 6% to 9% | 7+ years |
| Core-plus | Contracted midstream, economy-sensitive transport | 9% to 12% | 6+ years |
| Value-add | Data centers, fiber, greenfield assets | 12% to 15% | 5 to 7 years |
| Opportunistic | Merchant power, emerging markets, distress | 15%+ | 3 to 5 years |
Mercer attributes most of a core return to cash yield and almost all of an opportunistic return to capital growth, so the higher the band, the more the client behaves like a buyout fund and needs a sale at the end.
- Core-Plus Infrastructure
An infrastructure strategy that buys mostly operating assets with long-term contracts or concessions but accepts some volume, price or growth risk that core assets avoid, for higher target returns. Mercer puts typical manager targets at 9% to 12% net, earned from both cash yield and capital growth.
The vehicle matters as much as the band. A value-add flagship such as EQT Infrastructure VI, which closed at its €21.5 billion hard cap in March 2025, runs on a fund clock and will sell. Core money often sits in open-ended funds with no end date, such as Brookfield's Super-Core fund for mature utility and transport assets. A lower hurdle lets a fund pay more for the same cash flow and hold it longer, so contracted energy assets often pass from higher-return private equity owners to infrastructure funds, a hand-off traced in private equity's role in energy.
The Client List: Specialists and the Arms of Larger Firms
The family's core is a small group of specialist managers, three of them part of listed groups. The descriptions are the firms' own.
| Manager | Stated focus | Ownership | Vehicles a banker meets |
|---|---|---|---|
| Brookfield | Real assets and essential services | Brookfield Asset Management (listed) | Flagship funds, Super-Core |
| GIP | Energy, transport and digital | BlackRock since October 2024 | Flagship funds |
| Stonepeak | Infrastructure and real assets | Independent, unlisted | Infrastructure, real estate, credit |
| EQT Infrastructure | Essential-service companies | EQT (listed in Stockholm) | Value-Add, Active Core, Transition |
GIP reported more than $189 billion of assets under management (AUM) in October 2025; Stonepeak reports about $93 billion at March 2026, including capital committed since. The multi-strategy managers run large infrastructure arms too, placed beside their credit and buyout businesses in the mega funds comparison. The assets cluster in four groups:
- Regulated utilities and transmission, with returns set in rate cases
- Midstream pipelines, storage and processing under fee-based contracts
- Digital infrastructure: data centers, towers and fiber networks
- Transport: airports, ports, toll roads and rail
Sector mechanics belong to the sector guides, such as the technology and telecom guide's tower companies article and the real estate guide's private data center platforms. The coverage banker adds the client's view: which vehicle is buying, what band it underwrites to, and whether it wants control or a seat beside an operator.
Minority Stakes and Carve-Outs: How Corporates Create the Mandate
Buyout funds usually insist on control. Infrastructure funds will often take a minority stake, a joint venture (JV) interest or a carved-out network, because they want a long stream of distributions and a strong operator can be part of the asset. The corporate seller, rather than the fund, is then the usual source of the mandate.
Selling a Slice of a Regulated Utility
In August 2025 Duke Energy agreed to issue up to 19.7% of Florida Progress, the holding company of Duke Energy Florida, to Brookfield's Super-Core strategy for $6 billion in cash, which Duke's announcement called a significant premium to its public equity valuation. The money arrives in stages, $2.8 billion at a first closing and the rest by 2028, with $4 billion earmarked to reduce holding company debt. J.P. Morgan advised Duke and RBC Capital Markets advised Brookfield.
The first closing, on March 3, 2026, bought 9.19%, and Duke's quarterly filing says the proceeds displace planned issues of long-term debt and common equity through 2029. The seller raises equity without issuing parent shares or giving up control; the fund gets a non-controlling interest in a regulated utility, with rights set in an operating agreement.
Carving Out a Network
Carve-outs apply the same logic at larger scale. Telecom Italia (TIM) sold its fixed-line network, valued at up to €22 billion including earn-outs, in a deal completed on July 1, 2024. The new owner, FiberCop, is held 37.8% by KKR, 17.5% each by CPP Investments and the Abu Dhabi Investment Authority (ADIA), 16% by Italy's economy ministry and 11.2% by the Italian infrastructure fund F2i: one asset, five very different owners. The separation work follows the carve-out playbook.
Financing at the Asset, Not a Buyout Loan
The debt on an infrastructure deal rarely looks like a buyout loan. Most of it sits at the operating company, where a regulated utility or contracted pipeline already borrows long-dated in the investment grade bond or private placement markets, and regulators and lenders expect it to stay there. A fund wanting more leverage adds it above, at a holding company with no operations of its own.
- Holdco Debt
Debt raised by a holding company that owns an operating business but has no operations itself. It is repaid from dividends the operating company sends up after serving its own lenders, so it is structurally subordinated to operating company debt and usually rated below it.
Instead of an underwritten term loan B, the coverage banker therefore brings private placements sold to insurers that want long-dated, rated paper; operating company bonds; holdco term loans; and, for assets under construction, project finance, whose bond form is set out in the debt capital markets guide's project finance bonds article. Digital assets add securitization, as the data center financing explainer shows.
The operating company keeps refinancing for years after the deal, so debt capital markets (DCM) and project finance bankers stay close to these clients.
Regulators, Timetables and Who Covers the Client
Control of a regulated asset changes hands on the regulator's timetable, and the approval terms become part of the price.
The Approval Clock
CPP Investments and GIP agreed in May 2024 to buy ALLETE for $67 a share, $6.2 billion including assumed debt. Shareholders, the Federal Energy Regulatory Commission (FERC) and Wisconsin's regulator approved, but the Minnesota Public Utilities Commission (MPUC) voted only on October 3, 2025. ALLETE's announcement of the vote lists the price: about $200 million of customer benefits, including a one-year base rate freeze and $50 million of rate credits, plus the ROE cut, a majority independent board and guaranteed access to capital. The deal completed on December 15, 2025, about 19 months after signing. Minority stakes are reviewed too: Duke's Florida sale required FERC, the Committee on Foreign Investment in the United States (CFIUS) and a Nuclear Regulatory Commission determination.
Where the Client Sits Inside the Bank
Some banks cover infrastructure funds from the financial sponsors group, others from a power, utilities and infrastructure team that knows the assets, and the financing runs through DCM and project finance whoever holds the logo. Citi chose a hybrid in April 2026: alongside the new Financial and Strategic Investors group described in why banks cover a client type, it set up global infrastructure coverage as a separate, stand-alone vertical, WealthBriefing reported, led by a banker who keeps responsibility for power, utilities and renewables. ALLETE shows why the line blurs: one of its two buyers was a pension, the client type profiled in sovereign wealth funds and pensions as direct investors.
Whichever desk holds the account, the calendar is set outside the fund. A buyout client sells when its fund needs cash; an infrastructure client often buys when a utility's capital plan outruns its balance sheet, closes when the last regulator signs, then may stay for a decade of refinancings. Covering this client means following regulatory dockets as closely as fund vintages.
