PRESENTATION OF ANTIN 1 Antin model

Investment strategy expansion Supported by a global, well-diversified Fund Investor base, Antin has demonstrated that it can successfully expand its investment strategies and grow strategies to scale. Starting with a target size of €1.0 billion for its inaugural fund in 2008, Antin has been able to grow the size of its Flagship Fund Series over time, with its fourth fund in the Flagship Fund Series reaching €6.5 billion in commitments in 2020. In Spring 2021, Antin successfully launched Mid Cap Fund I, the first fund of the Mid Cap Fund Series, a new Fund Series focused on the mid cap market segment of the infrastructure asset class. Reaching the hard cap of €2.2 billion for Mid Cap Fund I is testament to Antin’s strong relationships with its Fund Investor base and its ability to launch complementary investment strategies that respond to investor demand. Also in 2021, Antin launched fundraising for NextGen Fund I, the first fund of the NextGen Fund Series, a new Fund Series focused on investing in the infrastructure of the future. Antin achieved a successful first close for NextGen Fund I in December 2021. Antin believes that operating a platform of scale is a key competitive advantage. Fund Investors want to work with managers that can raise and deploy significant amounts of capital. Such Fund Investors are choosing to concentrate allocations with firms who have an existing track record and can offer a range of different strategies. Having established a leading market position, Antin is well-positioned to meet the needs of its increasingly diversified institutional Fund Investor base by growing investment strategies to scale, as it has done with its Flagship Fund Series. Furthermore, Antin believes that its dual focus of searching for investment opportunities that have defensive infrastructure characteristics and at the same time have strong potential for value creation, remains a point of differentiation for Antin as compared to its peers. Antin seeks investment opportunities that benefit from long-term market trends, have identifiable value creation potential and demonstrate a degree of complexity. Antin also believes that it has demonstrated long-standing leadership with respect to responsible investment practices through its dedication to using sustainability as a value creation tool. Since inception and across economic cycles, this differentiated investment approach has resulted in a track record of delivering attractive, risk-adjusted returns across Antin’s Funds. Antin has achieved investment performance of 24% Gross IRR and 2.7x Gross Multiple on a realised basis across the Antin Funds. Antin believes that its established track record of stable returns is one of the key reasons Fund Investors choose to invest and reinvest in Antin Funds. 1.5.1.5 Proven fundraising success across an expanding and loyal investor base 1.5.1.4 Pioneering investment approach delivering attractive returns Founded in 2007, Antin has played a pioneering role in defining and shaping what was a nascent asset class at the time by employing a differentiated investment strategy, approaching the infrastructure market with a clear definition of the risk profile of an investment opportunity in order to identify compelling opportunities that may sometimes fall outside conventional ideas of infrastructure. This ability to innovate has allowed Antin to pioneer investments in new sectors which are sometimes not perceived as infrastructure by the wider market but which over time are seen as integral infrastructure subsectors.

Having identified investor relations as a critical success factor, Antin has remained committed to growing its investor relations team in tandem with the growth in the size of its managed funds. Since it was founded in 2007, Antin has raised fee-paying commitments of approximately €17 billion in seven funds across three investment strategies including ongoing fundraising of

NextGen Fund I. Antin has also increased the size of the funds in its Flagship Fund Series over successive fundraising cycles, growing from €1.1 billion for Flagship Fund I in 2008 to €6.5 billion for Flagship Fund IV in 2020. This represents an increase in size for each flagship fund by an average of ~80% over the prior fund raised.

Commensurate with the fundraising growth, Antin’s Fund Investor base has significantly expanded and become more balanced over time. Today, Antin counts over 210 institutions amongst its Fund Investors, almost tripple the count in 2015. Antin believes that a significant opportunity to further grow the Fund Investor base remains, as many institutional investors have yet to establish formal infrastructure allocations in their portfolio. Deepening existing relationships with Fund Investors provides another growth opportunity. Allocations by Fund Investors to the Antin Funds are increasing over time, with the average

commitment size per Fund Investor rising from €32 million in 2015 to €43 million in 2021. Antin believes that having played a pioneering role in defining and shaping the infrastructure asset class for 15 years and having delivered strong outcomes for its Fund Investors confer competitive advantages when it comes to raising capital for existing and new strategies. The deep and longstanding nature of Antin’s relationships with its Fund Investor base is illustrated by the 85% average re-investment rate achieved across its Flagship Fund Series.
