Macquarie Investment Management Global Limited

John F. O'Connor serves as Head of Macquarie Investment Management, overseeing the public-market and private-credit strategies. David Fass was appointed Global Head of Macquarie Asset Management in 2025, aligning MIMGL within the broader Macquarie Asset Management platform. Investment decisions are made by sector-specific teams within the asset management division, which reports to Macquarie Group's executive committee.

MIMGL benefits from Macquarie Group's integrated platform — the bank's corporate advisory, infrastructure placement, and debt capital markets desks originate deals that flow directly to the asset manager. This gives MIMGL access to infrastructure, real estate, and private credit opportunities that independent asset managers rarely see. Macquarie's global presence in Asia, Europe, and North America also enables multi-regional sourcing.

MIMGL is an institutional asset manager, not a family office. It is a regulated subsidiary of Macquarie Group, which is a listed financial conglomerate. Its investment strategies serve pension funds, sovereign wealth funds, insurance companies, and other institutional clients, not a single family or endowment.

MIMGL covers the full spectrum: public-market equities and fixed income for core mandates, private credit for direct lending and mezzanine, and infrastructure equity for greenfield and brownfield assets. It also participates in secondary transactions and co-investments alongside its fund vehicles. The firm does not typically target early-stage venture capital.

As part of Macquarie Asset Management, MIMGL frequently co-invests alongside its own infrastructure and real estate funds, as well as with external managers. It has participated in club deals and direct co-investments in large infrastructure assets such as Sydney Airport and renewable energy portfolios. The firm also originates separate accounts for large institutional clients that co-invest with the broader platform.

MIMGL has publicly stated it avoids direct exposure to tobacco, controversial weapons, and thermal coal mining (per Macquarie Group's responsible investment policy, 2025). It also excludes early-stage technology and venture capital from its core strategies, focusing instead on infrastructure, real assets, private credit, and public markets.

Macquarie Group operates the Macquarie Group Foundation, a philanthropic arm that is legally separate from the asset management business. MIMGL does not manage the foundation's assets; the foundation is funded by Macquarie Group's profit share and independent donations. This separation ensures that investment decisions are not influenced by charitable objectives.
