Heathrow Funding Limited H1 2026 Results Review: Debt, EBITDA and Credit Outlook

Heathrow Funding Limited H1 2026 Results Review: Strong Passenger Demand but Higher Costs and Debt

Heathrow Funding Limited’s half-year results for the six months ended 30 June 2026 show continued passenger demand, strong liquidity and resilient cash generation. However, rising operating costs and higher leverage remain key considerations for investors assessing Heathrow’s long-term credit profile.

Financial Performance

• Revenue: £1,729 million in H1 2026 compared with £1,724 million in H1 2025, an increase of £5 million.
• Adjusted EBITDA: £915 million in H1 2026 compared with £959 million in H1 2025, a decrease of £44 million.
• Cash generated from operations: £880 million in H1 2026 compared with £863 million in H1 2025, an increase of £17 million.
• Adjusted profit before tax: £115 million in H1 2026 compared with £121 million in H1 2025, a decrease of £6 million.
• Profit before tax: £447 million in H1 2026 compared with £203 million in H1 2025, an increase of £244 million.

The results highlight Heathrow’s ability to maintain strong cash generation, although profitability was affected by higher operating costs. Adjusted EBITDA declined by £44 million year-on-year despite passenger volumes remaining at record levels.

Passenger Growth and Operational Performance

Heathrow handled 40.0 million passengers during the first half of 2026 compared with 39.9 million passengers in the same period of 2025.

Passenger growth was supported by stronger international demand, particularly across Asia-Pacific routes, while transfer passenger volumes also improved. Heathrow continued investment in customer experience, security infrastructure and airport facilities.

Cost Pressures

The main pressure on earnings came from higher operating costs, including increased government-related charges such as business rates and national insurance costs, together with continued technology investment.

These factors contributed to adjusted EBITDA falling to £915 million in H1 2026 from £959 million in H1 2025.

Debt Position and Liquidity

Heathrow remains highly leveraged, reflecting the significant capital requirements associated with airport infrastructure.

• Heathrow SP net debt: £16,350 million in H1 2026 compared with £15,706 million in H1 2025, an increase of £644 million.
• Heathrow’s Regulatory Asset Base (RAB): £21,662 million in H1 2026 compared with £21,263 million in H1 2025, an increase of £399 million.

The company reported liquidity of £3.8 billion, providing a significant financial buffer and supporting near-term funding requirements.

Credit Investor Perspective

For bond investors, Heathrow continues to benefit from its position as a strategically important UK transport asset, supported by:

• Strong passenger demand and global connectivity
• A regulated revenue framework
• Significant liquidity reserves
• A growing Regulatory Asset Base

Key areas for investors to monitor include:

• High absolute debt levels
• Interest costs and refinancing requirements
• Regulatory decisions affecting charges and returns
• Capital requirements linked to expansion plans
• Exposure to geopolitical disruption affecting international travel

Third Runway Expansion Plans

Heathrow’s proposed third runway remains a major strategic focus. The expansion could increase long-term capacity and provide economic benefits, although it remains dependent on regulatory approvals, government policy and financing considerations.

Conclusion

Heathrow Funding Limited’s H1 2026 results demonstrate a resilient infrastructure business with strong passenger demand and substantial liquidity. The main challenges remain managing rising costs, maintaining cash flow generation and balancing future investment requirements with a highly leveraged balance sheet.

For bond investors, Heathrow’s long-term credit profile continues to depend on operational resilience, regulatory support and disciplined financial management.
