Igneo Infrastructure Partners is the direct equity infrastructure business of First Sentier Investors. For over 30 years we have been successfully investing in and managing infrastructure businesses across the world on behalf of a global base of institutional investors. We are one of the largest and most experienced direct investors in infrastructure assets globally, managing c. €17bn of client assets as at December 31 2022 on behalf of more than 120 institutional investors around the world.

Our vision & beliefs

Sourcing and investing in high-quality infrastructure businesses, where we see an opportunity to apply our operational skills and innovation, enables us to develop sustainable businesses that are leaders in their fields.

Great infrastructure businesses must have a foundation of excellent ESG management. A best-in-class health and safety culture, prudent management of environmental risks, diversity and inclusion, strong governance and high employee engagement are good for the company, its stakeholders and the environment.

Fundamentally, good ESG management reduces risk and improves long-term investment returns. This is at the heart of our approach.

Investment process & research

Infrastructure assets are inherently long-term in nature and therefore a long-term investment horizon is the most appropriate approach both for creating sustainable value and for investors to access an increasingly attractive asset class.

The ability to evaluate and manage unlisted infrastructure businesses enables Igneo to apply a much larger set of asset management tools and strategies to pursue sustainable value-add initiatives than a short-term or a conventional private equity style strategy.

With the above factors in mind, Igneo’s investment philosophy has been developed based on the application of the lessons learned from having more than 25 years’ experience as an infrastructure investor and manager. Igneo has learned how to provide the optimum balance between the ability to deliver diversification of risk and the practical requirement to be able to engage in and lead proactive asset management strategies that have been shown as the fundamental driver of long-term sustainable value creation.

Strategies & products

Igneo Infrastructure Partners offers institutional investors a range of both global and regional investment strategies as well as a choice of closed-ended and open-ended structures. 

We seeking to construct diversified portfolios of mature, unlisted, income-genersting infrastructure businesses operating in the energy, telecommunications, transportation and utilities sectors. We target sole, lead or co-lead roles in portfolio companies and require board representation. This enables us to proactively approach all aspects of the company and better influence the Environmental, Social and Governance (ESG) practices to add value, manage risks and act as a catalyst to adopt industry best practice.
