Airport Valuation Mandate for Infrastructure Investment
Independent valuation of an international airport conducted to support a strategic infrastructure investment
Description of the mandate: valuation of a European airport for an infrastructure fund stake
The engagement focused on the determination of the fair economic value of an international airport asset, on behalf of an investment fund entering the capital. The business valuation aimed to analyse long-term yield prospects and assess the robustness of the financial model in a complex regulatory environment.
The airport had a passenger capacity of several million per year, significant logistics infrastructure and an integrated portfolio of commercial and real estate concessions. The valuation was part of a strategic co-investment supporting facility modernisation.
Key challenges: valuing a regulated infrastructure asset over a long horizon
The main challenges of the mandate were:
- determining the economic value of a regulated infrastructure asset;
- modelling long-horizon future cash flows, integrating operating revenue, commercial royalties and non-aeronautical revenue;
- incorporating traffic rights and authorised air routes, which condition capacity and profitability;
- assessing the impact of airline concessions and slots on future value;
- ensuring consistency with international valuation standards (IVS, RICS).
Approach and outcomes: cross-checking long-cycle infrastructure DCF, RICS yields and sector multiples
The valuation deployed several complementary approaches:
- a discounted cash flow (DCF) approach, incorporating detailed assumptions on traffic, aeronautical and non-aeronautical revenue, CAPEX and regulatory evolution;
- a yield approach, based on expected profitability ratios for comparable airport infrastructures (RICS infrastructure benchmarks);
- a sector-specific multiples approach, based on a panel of international comparables (listed airports, secondary transactions on infrastructure funds);
- an analysis of the country risk premium and the financing structure typical of infrastructure projects.
The work enabled the determination of a coherent and defensible economic value range, accounting for regulation, traffic and expansion prospects. The analysis quantified the valuation's sensitivity to traffic assumptions, flight rights and airport pricing, as well as financing structure. The results showed a strong correlation between traffic volume and commercial concession performance (retail, car parks, duty-free), highlighting the complementarity between operating and real estate dimensions of the asset. The valuation served as the technical basis for negotiations between investors.
Illustrative example: numerical application to a European airport with 5M passengers
For illustrative purposes only — unrelated to the actual data of the mandate — a European airport with 5M passengers/year generating EBITDA of EUR 80M could exhibit an enterprise value range of between EUR 880M and 1.2bn based on 11.0x to 15.0x EBITDA multiples observed on infrastructure transactions (Vinci, Aena, Aéroports de Lyon). The long-cycle DCF (25-30 years) with WACC of 6-8% typical of regulated infrastructure refines the range, incorporating the residual capacity premium, slot value and commercial concession potential.
Summary: 7-week mandate, three cross-checked approaches, basis for co-investment negotiation
Business valuation mandate delivered in 7 weeks for a European airport in an infrastructure fund stake. Three approaches deployed (long-cycle DCF, RICS yields, sector multiples). Deliverable: independent report serving as the basis for negotiation between investors, incorporating sensitivity to traffic, flight rights and financing structure.
Frequently asked questions: airports, infrastructure, slots and long-cycle WACC
What multiples for a European airport?
For European airports, observed EV/EBITDA multiples on infrastructure transactions range between 10.0x and 16.0x, with a premium for (i) intercontinental hubs, (ii) high share of retail/non-aeronautical revenue, (iii) concession duration or full ownership, (iv) capacity expansion potential. EV/passenger multiples stand between EUR 200 and EUR 800/pax depending on profile.
Why a lower WACC for infrastructure?
Infrastructure benefits from a structurally lower WACC (5-9%) than conventional industrial companies (8-12%) due to (i) regulated cash flow predictability, (ii) long concession durations, (iii) natural barriers to entry, (iv) eligibility for ESG financing/green bonds. This stability premium justifies the high multiples observed.
How to value airport slots?
Slots (take-off/landing windows) constitute a valuable intangible asset, valued via (i) income approach (peak vs off-peak airport pricing differential), (ii) transaction comparables on slot sales in saturated hubs (Heathrow, Paris-CDG), (iii) real capacity option representing the right to accommodate additional traffic. Unit value can reach EUR 5-30M for a premium slot.
How long does an airport valuation take?
The standard duration is 6 to 10 weeks, depending on perimeter complexity (operating modes, concessions, integrated real estate) and access to operational data (traffic mix, seasonality curves, airline contracts). The mandate described was completed in 7 weeks.
What is the articulation between IVS and RICS?
IVS (International Valuation Standards) frame business and asset valuation generally. RICS (Royal Institution of Chartered Surveyors) provides complementary standards specific to real estate and infrastructure. Both frameworks are compatible and jointly deployed to ensure international enforceability of the report before investors and auditors.
Is the report usable for transactional closing?
Yes. An independent report compliant with IVS and RICS constitutes (i) a technical reference for pricing and negotiation, (ii) a fairness opinion that can be annexed to transactional documentation, (iii) a price allocation basis (PPA) for the acquirer's IFRS consolidation. To go further: PPA.
