You are an infrastructure fund, and you want to own one of these assets for the long term. This module walks the whole acquisition, how a deal is structured and run, what you underwrite, the suite of models you build, an interactive acquisition & returns model with a value-creation bridge, and a library of landmark deals that actually happened.
Infrastructure M&A is not trading. A fund buying a port, a regulated network or a wind farm is buying decades of cash flow and the obligation to keep an essential service running. The discipline is therefore different from corporate or growth-equity dealmaking: you underwrite durability before upside, you structure financing to survive the downside, and you plan the next owner's purchase on the day you sign yours.
Before any number is modelled, the question is whether the target has genuine infrastructure characteristics. The more of these it has, the more leverage it supports, the lower the return it can be priced to, and the longer it can be held. A "core" regulated network sits at one end; a merchant, demand-exposed asset sits at the other, and is priced for more risk.
People and economies cannot easily do without the service, and a competitor cannot simply build a parallel asset. High barriers to entry, a licence, a corridor, a coastline, a grid connection, protect the cash flow.
Revenue is underpinned by regulation (a RAB and allowed return), a long-term contract (PPP availability payment, PPA, take-or-pay), or deeply embedded demand. The buyer maps exactly how much revenue is contracted vs merchant.
Tariffs, regulatory settlements and concession payments are often explicitly indexed to CPI/RPI. That real-return profile is a core reason pension and insurance capital owns the asset class.
Assets last 30–100+ years and convert revenue to EBITDA at high margins once built. Maintenance capex is real but the operating cost base is thin relative to the cash thrown off.
Stable cash flows let the asset carry far more debt than a typical company, sized to a coverage ratio (DSCR) rather than an earnings multiple. Cheap, long, often investment-grade debt is central to the return.
The biggest threats are regulatory resets, re-tendered concessions, and government action, not demand collapse. The fund prices the regulatory period it is buying into and the political durability of the framework.
A buyer also fixes its style up front, because it sets the price it can pay and the return it must hit: core (regulated/contracted, ~7–9% target equity IRR), core-plus (some volume or merchant exposure, ~9–12%), value-add (build-out, repositioning, buy-and-build, ~12–16%), and opportunistic / greenfield (development and construction risk, 15%+). The same asset can be a different deal to a pension fund and to a value-add manager.
A competitive infrastructure auction runs 4–9 months from teaser to signing, with another few months to completion behind regulatory approvals. Bilateral and proprietary deals move on their own clock. The phases below are the path almost every deal follows.
The fund defines its mandate (geography, sector, risk style, cheque size, target return) and sources opportunities, through advisers running auctions, proprietary relationships, corporate carve-outs, take-privates of listed platforms, or secondary purchases from another fund.
Output: a pipeline and an initial fit screen against the fund's strategy and concentration limits.
A one-page teaser arrives; if it fits, the buyer signs an NDA and receives the Information Memorandum (IM) and a management presentation. A first-cut model and valuation range are built from this public-to-limited information.
Output: an internal screening paper and a preliminary view of value and fit.
The buyer submits a Non-Binding Offer (NBO), a price range, structure, financing approach, conditions and timetable. The seller shortlists bidders for the next round and opens the data room to them.
Output: NBO letter; admission to due diligence; an Investment Committee "go" to spend on advisers.
The core work. Parallel workstreams, commercial, financial & tax, technical, legal & regulatory, insurance, ESG, interrogate the data room, run site visits and expert sessions, and feed findings into the model. Debt providers run their own diligence in parallel.
Output: red-flag and full DD reports, a fully diligenced model, a financing package and a risk-allocation map.
The buyer submits a Binding Offer with a markup of the Sale & Purchase Agreement (SPA), committed (or highly confident) financing and final IC approval. Negotiation centres on price, the locked-box/completion-accounts mechanism, warranties & indemnities (and W&I insurance), conditions precedent and the management package.
Output: a signed SPA and shareholders' agreement; debt commitment letters.
Between signing and closing, conditions precedent are cleared: merger control / antitrust, sector regulator consent, foreign-investment screening (FDI), and lender conditions. Debt is drawn, equity is funded, and ownership transfers at completion.
Output: regulatory clearances, funds flow, completion, the asset is now owned.
The 100-day plan executes: governance and board, management incentives, reporting and KPIs, the capital programme, refinancing, bolt-on M&A, operational improvement and the ESG/decarbonisation plan. This is where most of the return is actually built, year after year.
Output: a performing asset delivering the business plan; periodic distributions to the fund.
At the right point in the hold (typically 7–15 years, often longer for core), the asset is sold to another fund, a strategic, or via IPO, or recycled into a long-hold/open-ended vehicle. The exit thesis was set at entry; the bid the next buyer can pay is the cap on this fund's return.
Output: realised proceeds, a final IRR and money multiple, and a track record.
Diligence is run as parallel workstreams, each by specialists, all feeding one model and one risk-allocation view. The recurring question is the same: which risks stay with the buyer, and which can be passed to the seller (warranties/indemnities), to lenders, to insurers, or to contractors and the regulator?
The market, demand drivers, competitive position, customer/counterparty concentration, contract terms and the volume vs price story. For regulated assets: the framework, the current settlement, and reset risk. The independent "commercial DD" report often anchors the base-case revenue.
Quality of earnings, is reported EBITDA real, recurring and clean of one-offs? Working capital, net debt at completion, capex history, and the tax structure (holding-company location, withholding tax, interest deductibility, capital allowances).
Asset condition, remaining life, the maintenance and capex programme, technology and obsolescence, health & safety, and the operating cost base. Engineers price the lifecycle and stress the capex line, usually the biggest model swing after revenue.
Title and the licence/concession, change-of-control and consents, the regulatory contract and its enforceability, litigation, key contracts, and the SPA risk allocation (warranties, indemnities, conditions). Antitrust and FDI clearance feasibility is assessed here.
Physical climate risk to the asset, transition risk (stranding of carbon-exposed assets), permitting, environmental liabilities and remediation, biodiversity, community and political/social licence to operate. Increasingly a gating item for the fund's own LPs.
Insurability and the cost of cover (a real opex line for catastrophe-exposed assets), plus an independent model audit to confirm the financial model is mechanically correct and that lenders and IC are relying on the same numbers.
There is one model, a single, audited Excel operating & financial model, and several lenses onto it. It projects the asset's cash flows for the full hold (and often the full concession/asset life), drives the debt, and produces the valuation and returns. The lenses below all read from it.
The source of truth: revenue built bottom-up (volumes × price, or RAB × allowed return, or contracted payments), the full opex and maintenance-capex base, tax, working capital and a three-statement or cash-flow waterfall. Monthly or annual, with an explicit forecast period and indexation.
A DCF of unlevered free cash flow at the asset WACC (or a dividend-discount / equity cash-flow model); cross-checked against trading and transaction comparables (EV/EBITDA, EV/RAB, $/MW, $/passenger). Regulated assets are also valued at a premium/discount to RAB. Sum-of-the-parts for platforms.
Sources & uses, debt sized to a target gearing and coverage (DSCR/ICR), the cash-flow waterfall and distributions, and the equity return, IRR and money multiple (MOIC), over the hold, with an exit at an assumed multiple. The value-creation bridge decomposes the return.
One- and two-way data tables on the value drivers, a downside/management/upside case set, Monte-Carlo on key variables, and break-even analysis (e.g. the price at which covenants breach). This is what the Investment Committee actually debates.
The acquisition & returns lens (C) is the one that decides the price. Use the live model below to see how the headline drivers, what you pay, how much debt you raise, how fast EBITDA grows, and what you sell for, combine into an equity return, and how the value-creation bridge attributes that return to growth, re-rating, deleveraging and cash yield.
A buyout of a single asset, built the way a deal team would. Set the four headline value drivers on the sliders, then refine the operating assumptions below, inflation and indexation, maintenance and growth capex, tax, the debt-sizing and terminal-value method. The sources & uses, the equity return (nominal and real) and the value-creation bridge update live. Crucially, real growth is paid for with growth capex, and EBITDA growth is split into the part that is merely inflation indexation and the part that is genuine real value.
Start from a generic, illustrative asset, or load any of the 216 worked assets from across the reference library, and the model pre-fills its EBITDA, multiple, leverage, growth and hold from that page's financials.

Each cell re-runs the full model holding everything else at the current settings; the outlined cell is today's case. Read it as the bid (entry multiple) you can justify for a target return, against the exit you assume.
How it works. Entry EV = entry multiple × EBITDA; the equity cheque = EV + transaction costs − new debt. Debt is sized either by leverage (Net debt/EBITDA, capped at 85% of EV) or to a target DSCR, the supportable annuity = year-1 CFADS (cash conversion × EBITDA − maintenance capex) ÷ DSCR, annuitised over the tenor; the reported DSCR is the minimum across the whole hold, after tax. Each year, nominal EBITDA growth is split into inflation indexation (the inflation-linked share × inflation) and real growth; only real growth is paid for, with growth capex = the chosen multiple × the real EBITDA increment. The cash waterfall runs EBITDA → less maintenance capex → less cash tax (on EBITDA − straight-line tax depreciation − interest, with a loss carry-forward and the interest shield) → less cash interest → less growth capex; surplus is split between debt sweep and distributions, and any shortfall is drawn on a revolver. An optional index-linked tranche accretes its principal with CPI. Terminal value is either exit multiple × terminal EBITDA, or, for a finite concession, the discounted run-off of the remaining contracted cash flows to handback (debt repaid from that run-off). The IRR uses the dated equity cash flows (a real IRR deflates it by inflation); MOIC = total proceeds ÷ equity cheque; returns are gross of fund management fees and carry. The bridge reconciles exactly: equity cheque + indexation + real growth (both at the entry multiple) + re-rating (terminal value vs entry multiple × terminal EBITDA) + debt paydown + distributions − transaction costs = total proceeds. Real-asset figures are pulled from each reference page's model in that asset's native currency; they are illustrative, not a forecast, and the operating assumptions (capex, tax, indexation) are stylised by asset class. The model still omits construction phasing, working-capital detail and the full HoldCo tax structure. Not investment advice.
The model says what to pay; the structure decides how the price is set, who carries the risks the diligence surfaced, and how the equity cheque is minimised. These are the levers negotiated into the SPA and the financing package.
Locked-box (a price fixed to a recent audited balance sheet, with no post-completion true-up but a "no-leakage" covenant) or completion accounts (price adjusted for actual net debt and working capital at closing). Locked-box dominates competitive infra auctions, it gives certainty and speed.
The seller warrants the business; the buyer's recourse for breaches is increasingly placed with a warranty & indemnity (W&I) insurer rather than the seller, giving a clean exit to the seller and a solvent counterparty to the buyer. Specific indemnities ring-fence known risks (tax, litigation, environmental).
The gap between signing and completion exists to clear merger control, sector-regulator consent and foreign-investment (FDI) screening. Each is a real execution risk, and a reason deals fall over. Long-stop dates, break fees and interim-period covenants govern the gap.
A chain of holding companies (often in a treaty-friendly jurisdiction) houses the debt, manages withholding tax on distributions, preserves interest deductibility within local thin-cap/earnings-stripping limits, and ring-fences the asset for the lenders. Set up at entry with the exit and co-investors in mind.
Senior debt sized to a minimum DSCR and gearing, with tenor, amortisation/cash-sweep, hedging (interest-rate and, for cross-border deals, FX) and covenant package negotiated with the lenders or bondholders. A refinancing at a lower margin once de-risked is a deliberate part of the return, model the debt-sizing toggle above.
The shareholders' agreement sets board seats, reserved matters, drag/tag rights and the distribution policy across the consortium. Management is incentivised (a ratchet / co-invest) to the business plan, and minority and co-investment stakes are syndicated to LPs alongside the fund.
A selection of significant, well-documented infrastructure acquisitions across sectors and decades, the kind of transactions this module describes, actually executed. Values are at announcement and mix enterprise value and equity value as reported; figures are rounded. Filter by sector or sort any column.
Open the full deals database, filter by sector, region & deal type →Reading the table. "Deal value" is as reported at announcement, some figures are enterprise value (including assumed debt), some are equity/offer value, and consortium deals are the whole transaction, not one party's stake. Several deals later took very different paths (Thames Water's eventual restructuring; the CK Hutchison ports portfolio, agreed with a BlackRock-led consortium in 2025, was subsequently contested in Panama), a reminder that the entry is only the start of the ownership story.
Deal figures are drawn from company announcements, regulatory filings and contemporaneous trade and financial press, including:
