1.5.1 Key strengths

The strength of Antin’s culture can be seen in the stability of the senior management team, with an average tenure of ten years and the very low level of turnover seen amongst its wider investment team. 1.5.1.2 Fast growing private market segment Antin benefits from operating in a highly attractive and fast-growing market, with private markets growing rapidly overall, benefitting from multiple structural growth drivers and infrastructure being among the fastest growing asset classes within private markets. Further detail on infrastructure market is available in Section 1.1 “ Industry overview ” of this Universal Registration Document.

1.5.1.1 Strong cultural values based on four founding principles Antin is a differentiated private markets firm, with a strong focus on culture and with a consistent set of principles as outlined in the introduction of this Universal Registration Document (see “Business Model”) , which have been in place since its foundation. Antin believes its culture to be a critical source of competitive advantage, enabling it to position itself as an attractive home for the best investment teams in the industry and as an attractive prospective owner of businesses. A strong and stable culture is also of high importance for Fund Investors given the long-standing nature of the commitments made when investing.

1.5.1.3 Pure-play leadership in infrastructure with global growth and expansion Antin is a leading independent infrastructure investor as evidenced by the second highest quantum of capital raised across its relevant peer group of European headquartered firms.

Geographical expansion From its roots in Europe, Antin has been able to build one of the largest pure-play investment platforms focused on infrastructure investments active in Europe and North America, supported by a global investor base. Having initially established a reputation and track record of sourcing and executing attractive infrastructure investments in Europe, Antin saw it as a natural next step to explore similar investment opportunities in North America. The first milestone of this geographical expansion was reached in 2018 when Antin acquired its first US portfolio company. In 2019, following this first acquisition, Antin announced the opening of its New York office with the aimof creating a geographic presence to serve as abase for further investments in North America. In addition to its offices in Paris and London, the New York team included over 20 investment professionals on 31 December 2021 (expanding to 35 as of the date of this Universal Registration Document). Antin also expanded its geographical reach in Asia-Pacific with the establishment of an office in Singapore dedicated to fundraising effort.

For nearly 15 years Antin has been researching relevant macro trends, refining its investment approach and deepening its network of relationships with industry players. This focus and dedication have positioned Antin as a partner of choice for business and asset owners considering disposals. This is particularly relevant when developing a dialogue with infrastructure corporates that are considering a carve-out of a business unit or in conversations with founders deciding to whom to entrust stewardship of their business for the next phase of ownership and development. Antin believes that it has significant scope for further attractive growth given the large size of the global private infrastructure market (~€860 billion) (2) versus Antin’s current size. Antin has substantial opportunity to continue to scale its existing strategies and to add new complementary strategies as outlined below.
