CHAPTER 5

Built for today’s environment

Infrastructure valuations have moved closer to historical norms while remaining competitive relative to public markets. Valuation levels continue to vary across sectors and market cycles, creating opportunities for investors to allocate selectively based on fundamentals and long-term demand drivers.


Private infrastructure valuation multiples have moderated from recent highs and are now broadly in line with historical ranges. While valuations can fluctuate over time, current EV/ EBITDA multiples suggest entry points that are more consistent with long-term averages.

Entry EV/EBITDA private infrastructure transaction multiples

Key takeaway

Entry valuation multiples have moved closer to long-term historical norms.

Macquarie Asset Management, Bloomberg (October 2025). Private infrastructure time series is based on 1,222 transaction multiples from January 2008 to June 2025 (see methodology for details). Past performance is not indicative of future results. For illustrative purposes only.


Private infrastructure has historically traded at a valuation premium to listed equities, reflecting its defensive characteristics and contracted revenue base.

Recent data shows that premium has narrowed relative to historical norms – a shift that reflects both the interest rate environment and the growth in institutional demand for the asset class.

Private infrastructure valuation multiples compared to listed equities

Key takeaway

The valuation premium historically associated with private infrastructure has narrowed relative to listed equities.

Bloomberg, Macquarie Asset Management (March 2026). Private infrastructure series is based on 1,338 data transaction multiples for deals that reached financial close between January 2008 and December 2025 (see methodology for details). For illustrative purposes only. Past performance is not indicative of future results.

What drives infrastructure valuations?

Infrastructure valuations have historically been more sensitive to interest rates and inflation than to economic growth. Periods characterised by moderating rates and stable inflation have tended to be supportive of infrastructure valuations.

Interest, Yield, Revenue, Profit, Return, Dividend, Earnings, Gain, Percent, Percentage, Increase, Decrease

Interest rates

Higher interest rates have historically been associated with lower infrastructure valuation multiples

Inflation

Infrastructure valuations have historically shown a positive relationship with inflation.

GDP Growth

Infrastructure valuation multiples have historically shown limited direct relationship with GDP growth.

Valuation levels vary meaningfully across infrastructure sectors, reflecting distinct demand drivers, growth profiles and risk characteristics.

Key takeaway

Valuation dispersion across sectors may create more selective investment opportunities.

As of September 2025. Macquarie Asset Management (September 2025). Past performance is not indicative of future results. For illustrative purpose only. Utilities include regulated utilities, contracted power generation (excluding renewables), district heating and other segments. Diversified infrastructure mainly includes waste management, healthcare, car parks and education. Energy midstream refers to LNG terminals, oil & gas pipelines.

Like most asset classes, infrastructure can experience periods of weaker performance, particularly during economic downturns or when real interest rates rise.

As the chart illustrates, these periods have historically been temporary. In both the GFC and COVID‑19, returns recovered as the underlying demand for essential infrastructure services remained broadly intact.

Private infrastructure returns

Key takeaway

Periods of weaker performance have historically been temporary, with returns recovering as demand for essential infrastructure services remained intact.

Portfolio and risk metrics

Efficient frontier: The set of portfolios offering the highest expected return for a given level of risk, or the lowest expected risk for a given level of return.

Volatility: A measure of how much an asset’s returns fluctuate over time. Higher volatility indicates greater variability in returns.

Correlation: A measure of how closely the returns of two assets move together. Lower correlation between assets can contribute to portfolio diversification.

Drawdown: The decline in an investment’s value from a previous peak to a subsequent low, used to assess the severity of losses during periods of market stress.

Standard deviation: A statistical measure of the variation in returns, commonly used to quantify volatility.

 

Macroeconomic terms

GDP: Gross Domestic Product. The total value of goods and services produced within a country.

CPI: Consumer Price Index. A measure of the average change over time in the prices paid by consumers for a basket of goods and services, commonly used as a measure of inflation.

Deglobalisation: A shift towards less globally integrated trade and production, often reflected in more regionalised supply chains and a greater focus on domestic resilience.

 

Financial and valuation metrics

EBITDA: Earnings Before Interest, Taxes, Depreciation and Amortisation. A common measure of operating profitability.

EV/EBITDA: Enterprise value, or EV, measures a company’s total value and, when compared with its EBITDA, shows whether the company is overvalued or undervalued.

CAGR: Compound Annual Growth Rate. The constant annual rate at which an investment or metric would have grown over a specified period, assuming compounding.

Unsmoothed returns: Returns are adjusted to remove the artificial calm from lagging appraisals so a private investment’s true volatility can be fairly compared with daily-priced assets.

 

Infrastructure-specific terms

Contracted or regulated revenues: Revenues governed by contractual agreements or regulatory frameworks, which can provide greater visibility over future cash flows.

Concession agreement: An agreement granting a private operator the right to develop, operate or maintain an infrastructure asset for a specified period, subject to defined terms and obligations.

Energy midstream: Infrastructure involved in the transportation, storage and processing of energy commodities between production and end-market distribution.

Private and listed infrastructure: Private infrastructure comprises unlisted assets typically held directly or through private funds. Listed infrastructure comprises publicly traded companies that own or operate infrastructure assets.

Research methodology

Unsmoothed returns

Unsmoothed returns: Returns are adjusted to remove the artificial calm from lagging appraisals so a private investment’s true volatility can be fairly compared with daily-priced assets.

Private and listed equity valuation comparisons: Comparisons between private and listed equity valuations are subject to differences in valuation methodology, asset liquidity and risk profile.

 

Methodology pertaining to chapter 5

To ensure the time series is as accurate and representative as possible, we have used the following principles to build it:

Quality sources: We have used our trusted internal database of EV/EBITDA multiples and reliable external data sources, such as Inframation and Bloomberg.

Large sample size: Our database contains 1,054 data points for private infrastructure transactions that reached financial close between 2008 and 2022, inclusive.

Long history: Our time series covers a period of 15 years, including two recession periods, the GFC and COVID-19, and two recoveries.

Strict definition: The dataset primarily includes brownfield assets that are underpinned by regulated or contracted cash flows, with limited exposure to assets with significant merchant risk.

Diversification by sector: The dataset is well diversified by sector, including transport, utilities, digital infrastructure, renewables, energy midstream and diversified infrastructure.

Diversification by country: The dataset is also well diversified by country, with the largest exposures being to the US, UK, Spain, Italy, France and Australia.

Transparent approach: No adjustments have been applied to the reported multiples, except for the calculation of monthly, or quarterly where applicable, moving averages.

Diversification may not protect against market risk.

Market risk is the risk that all or a majority of the securities in a certain market – like the stock market or bond market – will decline in value because of factors such as adverse political or economic conditions, future expectations, investor confidence, or heavy institutional selling. International investments entail risks including fluctuation in currency values, differences in accounting principles, or economic or political instability. Investing in emerging markets can be riskier than investing in established foreign markets due to increased volatility, lower trading volume, and higher risk of market closures. In many emerging markets, there is substantially less publicly available information and the available information may be incomplete or misleading. Legal claims are generally more difficult to pursue.

Currency risk is the risk that fluctuations in exchange rates between the US dollar and foreign currencies and between various foreign currencies may cause the value of an investment to decline. The market for some (or all) currencies may from time to time have low trading volume and become illiquid, which may prevent an investment from effecting positions or from promptly liquidating unfavourable positions in such markets, thus subjecting the investment to substantial losses.

Credit risk is the risk of loss of principal or loss of a financial reward stemming from a borrower’s failure to repay a loan or otherwise meet a contractual obligation. Credit risk arises whenever a borrower expects to use future cash flows to pay a current debt. Investors are compensated for assuming credit risk by way of interest payments from the borrower or issuer of a debt obligation. Credit risk is closely tied to the potential return of an investment, the most notable being that the yields on bonds correlate strongly to their perceived credit risk.
