Antin Infrastructure Partners

The firm is led by a partnership of managing partners including Alain Rauscher (CEO), Mark Crosbie (Managing Partner for the UK and North America), and Sébastien Feix (COO and Managing Partner). Founding partner Bruno Candès remains active within the firm. Investment decisions are made by the partnership collectively, with sector-specific teams leading due diligence on each deal (per Antin's 2021 firm overview).

Antin sources deals primarily through a combination of direct origination from its sector specialists — who maintain relationships with developers, governments, and corporate vendors — and selective participation in competitive processes. The firm avoids auctions where it has no informational advantage, and instead focuses on negotiated transactions, carve-outs from corporates, and partnership opportunities with public entities (per Infrastructure Investor, 2020).

Antin is structured as an independent partnership, not a family office. It operates as a regulated asset manager under the management of its founding partners, who are not representing a single family’s capital. The firm raises institutional capital from pension funds, sovereign wealth funds, and insurance companies. This structure means its investment mandate is driven by fund-level objectives rather than the preferences of a single wealthy family.

Antin manages blind-pool closed-end funds that commit capital directly to infrastructure assets. The firm does not run a fund-of-funds or separately managed account business at scale. Investors in Antin funds commit to the firm’s sector and geographic strategy; the firm then deploys that capital into specific assets. There is no vehicle for co-investments alongside external GPs, though Antin itself may accept co-investors on a deal-by-deal basis (per Infrastructure Investor, 2021).

Antin focuses on core-plus infrastructure investments in mid- to large-cap assets — typically above €200 million in equity value per deal. The firm targets operational or near-operational assets in regulated or contracted environments, rather than greenfield development. However, with the launch of Antin NextGen Infrastructure, the firm has expanded into growth-stage assets such as energy-transition platforms or digital infrastructure companies that require capital for expansion, but still target a lower-risk profile than pure venture (per Infrastructure Investor, 2023).

Antin has publicly stated it avoids merchant-energy assets that carry commodity-price exposure — i.e., un-hedged power plants or hydrocarbon-dependent generation. The firm also avoids shipping and aircraft leasing, and has historically rejected any infrastructure with material technology obsolescence risk. Its focus is on essential-service assets with predictable, inflation-linked cash flows (per Antin's 2021 investor presentation).

Antin typically leads its own deals as a GP and does not serve as a passive co-investor behind other infrastructure managers. However, the firm has partnered selectively with other GPs on large transactions where it takes a co-leading role. For example, in 2020, Antin co-acquired the Spanish telecom fiber operator Avatel with another infrastructure fund, acting as a joint controlling investor (per Reuters, 2020). In general, the firm prefers to control assets.
