One River Asset Management has signed a definitive purchase agreement with Switzerland-based LGT Capital Partners to acquire the core team members, intellectual property, and derived investment strategies of LGT Capital Partners’ Quantitative Investment Solutions business unit.
The transaction is expected to close midway through the 2026 calendar year. Upon completion, the acquired business will operate as One River Switzerland AG, a wholly owned subsidiary of One River. The deal is expected to add more than $900 million in Day 1 assets under management across the transferred strategies.
LGT Capital Partners, a global alternative investment specialist with over $110 billion in assets under management, is transferring its eight-person QIS hedge fund team along with two long-established systematic strategies. The strategies will be renamed One River Dynamic Protection, a systematic multi-asset futures-based long volatility strategy with an 11-year live track record, and One River Systematic Macro, a multi-asset systematic macro strategy with a nearly 10-year live track record.
LGT Capital Partners will remain meaningfully invested in both strategies following the transaction.
As part of the integration, Stephen Prajna will continue to serve as Deputy CIO of Risk Mitigating Strategies, leading One River’s core systematic suite. The acquisition also brings three new partners to the firm. Jean-François Bacmann will join alongside Prajna as Deputy CIO of Diversifying Strategies. Pascal Spielmann will become President of One River Switzerland, and Simone Villa will serve as Chief Technology Officer. Christian Jung will join as COO and CRO of One River Switzerland.
The acquisition expands One River’s systematic investment capabilities and establishes its first European footprint. The firm said the addition of complementary strategies enhances its ability to deliver lowly correlated, positively convex, capital-efficient solutions that can be rebalanced alongside core portfolio exposures. By integrating the strategies within its broader platform, One River aims to improve capital efficiency, reduce fee layering, and offer partially funded structures such as separately managed accounts.
One River manages approximately $3 billion in assets and focuses on macro-aware, systematic risk mitigation strategies for institutional investors.
LGT Capital Partners oversees more than $110 billion in assets and serves over 700 institutional clients across 50 countries, with investment programs spanning private markets, multi-alternatives, diversifying strategies, and sustainable and impact investments.
