HarbourVest Infrastructure Opportunity Fund III

HarbourVest Infrastructure Opportunity Fund III is an opportunistic infrastructure secondary fund designed to invest in existing infrastructure assets across North America and Western Europe. It is structured to acquire stakes via secondary market transactions, providing liquidity and access to mature infrastructure exposures. The fund leverages HarbourVest’s global platform and relationships to source differentiated opportunities. The investment strategy focuses on buying into infrastructure assets that are already operating or nearing maturity, thus reducing development risk. The fund seeks value creation through operational improvements, capital optimization, and repositioning of assets when appropriate. Risk management, ESG integration, and alignment with long‑term infrastructure trends are central to its approach. The target fund size was approximately USD 865 million , as achieved at final close. The fund is positioned to supplement HarbourVest’s previous infrastructure vehicles and intends to double down on the firm’s track record in private markets, applying lessons from prior vintages to drive performance in a dynamic macro environment. The blend of geography, structure, and asset maturity is intended to deliver resilient returns. HarbourVest intends for IOF III to act as a bridge between high-barrier infrastructure deals and institutional investors seeking exposure via secondary markets. The fund targets a diversified portfolio across sub‑sectors including energy, transport, utilities, digital infrastructure, and natural resources, with careful attention to inflation linkage, regulatory risk, and cash yield.
