In a landmark transaction poised to reshape the future of Indian aviation infrastructure, Adani Airports Holdings Ltd (AAHL) has secured $1 billion in project financing for the development and modernisation of Mumbai International Airport Ltd (MIAL). This marks a historic first: the country’s maiden investment-grade private bond issuance in the airport infrastructure sector, signalling a surge in global investor confidence in India’s aviation ecosystem.
According to The Economic Times, the funding comprises a $750 million senior secured note issuance maturing in July 2029, primarily intended to refinance existing debt, along with a $250 million accordion feature, allowing further capital to be drawn as needed. The entire facility has been structured as part of a long-term strategy to support the transformation of Mumbai Airport into a world-class, sustainable aviation hub.
“This successful issuance validates the strength of the Adani Airports’ operating platform, the robust fundamentals of Mumbai International Airport, and our commitment to sustainable infrastructure development,” said Arun Bansal, CEO of Adani Airports Holdings Ltd. “With participation from Apollo-managed funds and leading institutional investors, we are proud to deepen our access to global pools of capital.”
The investment was led by Apollo Global Management, one of the world’s largest alternative asset managers. Additional backing came from BlackRock-managed funds and Standard Chartered, among others, collectively underscoring the credibility of Adani’s airport platform and the growing appeal of Indian infrastructure assets to global investors.
What sets this deal apart is not just its scale, but its investment-grade rating, a notable achievement in a space traditionally reliant on government funding or lower-rated private credit instruments. This shift highlights India’s maturing infrastructure financing landscape, where robust governance, strong project fundamentals, and private-sector execution are increasingly attracting international capital.
“This is more than just a financing deal; it’s a signal that India’s airport sector is evolving into a global-grade investment destination,” noted a senior aviation analyst. “The fact that institutional investors are willing to commit to long-tenor capital reflects growing confidence in both the sector’s growth trajectory and Adani’s operational credibility.”

The capital raised will be deployed toward an ambitious transformation plan at Mumbai International Airport, India’s second busiest airport by passenger traffic. Adani’s vision includes:
- Capacity expansion to accommodate growing passenger and cargo volumes
- Terminal upgrades to enhance customer experience
- Technological innovations for improved efficiency and digital passenger services
- Infrastructure improvements aligned with international standards
Crucially, a significant portion of the funding is earmarked for sustainability initiatives. Mumbai Airport has committed to achieving net-zero emissions by 2029, placing it among a select group of global airports with aggressive environmental targets. This will involve:
- Transitioning to renewable energy sources
- Electrifying ground support equipment
- Investing in sustainable aviation fuel (SAF) infrastructure
- Enhancing water and waste management systems
These efforts align with India’s broader climate goals and strengthen the airport’s positioning as an environmentally conscious gateway to South Asia.
This transaction also represents a critical pillar of the Adani Group’s broader infrastructure and capital allocation strategy. With operations spanning airports, ports, energy, logistics, and digital infrastructure, the Group has positioned itself as a key driver of India’s next phase of economic development.
Arun Bansal emphasised that the financing reflects a disciplined approach to capital deployment, with an emphasis on long-term value creation and global best practices.
“Our ability to secure one of the largest private investment-grade project finance deals in the country is a testament to our financial strategy and operational strength,” he said.
This deal is the latest in a series of high-profile financial moves by Adani aimed at strengthening liquidity, reducing leverage, and unlocking value across its portfolio, particularly after facing scrutiny in early 2023 over corporate governance and debt levels. The company’s renewed focus on transparency, sustainability, and global investor alignment appears to be yielding tangible results.
India’s aviation industry is entering a phase of exponential growth, fuelled by a rising middle class, expanding regional connectivity, and policy reforms under initiatives like UDAN and the National Infrastructure Pipeline (NIP). According to the International Air Transport Association (IATA), India is expected to become the third-largest aviation market globally by 2030, with passenger traffic surpassing 520 million annually.
Mumbai Airport is expected to play a central role in this growth narrative, serving as a critical hub for both domestic and international travel, while easing capacity pressures on Delhi and Bangalore.
Adani’s $1 billion raise comes at a pivotal moment, setting a precedent for privatised, digitally driven, and sustainability-focused airport development. It is not just an infusion of capital, it’s a blueprint for future airport infrastructure financing in India, blending global capital, green ambition, and infrastructure modernisation.
With this landmark transaction, Adani has effectively redefined the playbook for infrastructure financing in India’s aviation space. By tapping global markets through an investment-grade offering, and by aligning capital deployment with environmental and operational excellence, the Group is demonstrating how Indian companies can compete and lead, on the global stage.
As the aviation sector continues to evolve, this financing deal may well be remembered as a turning point, where India’s airports moved from being public utilities to investment-grade global assets, with Adani at the forefront of this transformation.
