A MILESTONE YEAR FOR ANTIN 2021 was a remarkable year for Antin. We grew our assets under management by 24% while delivering continued exceptional returns to our Fund Investors. We expanded our investment capabilities and launched two new strategies, marking the beginning of a new era in Antin’s growth journey. We made continued progress as a responsible investor and upheld high ESG standards across our business and portfolio companies, making Antin a true sustainability champion. We also grew the firm’s partnership and team with 53 new hires to be appropriately resourced to manage a materially larger pool of assets as we continue to scale up the business. In addition to that, we took a game changing step with our IPO on the Euronext Paris stock exchange, attracting strong demand from diverse and globally renowned investors. We are heartened by the success of the IPO, which provides us with the capital to fund our ambitious growth plans while also substantially enhancing the global visibility of the Antin brand. While all these achievements make us proud, we are confident that the best is yet to come. PIONEERING INFRASTRUCTURE PRIVATE EQUITY We started Antin in 2007 with the vision to create a different kind of infrastructure investment firm. One that applies private equity methods to the infrastructure asset

class, combined with an entrepreneurial culture in which talents can thrive. We were convinced that we could deliver superior investment returns to our Fund Investors by transforming infrastructure businesses through active ownership, which wasn’t widely practiced at the time. As such, we were pioneers in executing a value-add strategy in infrastructure in Europe. With dedication and discipline, we have raised four Flagship funds, each new one being on average ~80% larger than its predecessor. These funds have been invested in more than 30 portfolio companies since inception and achieved a 2.7x Gross Multiple across all realised investments. Today, our methods are proven, and we are the largest pure-play infrastructure private equity firm in Europe, delivering consistent best-in-class returns for our Fund Investors in the fastest-growing segment within private markets. ENTERING AN EXCITING PHASE IN ANTIN’S GROWTH JOURNEY In 2021, we successfully launched two new investment strategies to complement our Flagship Fund Series. Our Mid Cap fundraising was one of the fastest we ever completed and attracted significant demand from both existing and new Fund Investors. The NextGen strategy also started fundraising with strong momentum as we reached a first close in December 2021. The only difference between the Mid Cap and Flagship Fund
