Funds managed by Foresight Group (“Foresight”), a leading, listed, sustainability-led alternative asset investment manager with £12 billion* of assets under management, have completed the acquisition of LionFish Litigation Finance Limited (“LionFish”) from AIM-listed professional services firm RBG Holdings Plc (“RBG”).

LionFish was launched in May 2020 as a subsidiary of RBG. Built on strong principles and a solid operating infrastructure, LionFish quickly established its presence in the market and experienced rapid growth. To accommodate its growth, LionFish entered a co-investment arrangement with Foresight in February 2022. Intended to be the first of many, this co- investment afforded LionFish the ability to expand its capital investment base and reduce its reliance on RBG’s balance sheet.

In December 2022, RBG announced intentions to refocus on professional services and received several bids to acquire the LionFish business. Foresight’s bid was unique and stood out given its patient capital base, long-term commitment and alignment with LionFish’s ambitions and investment thesis.

Foresight’s acquisition will provide LionFish with the stability and support to leverage its team, its principal investment model, and its operational efficiency. Operationally, LionFish will remain an independent company run by management team Tets Ishikawa and Tanya Lansky, with general oversight from a soon to be announced and newly appointed board. Its existing transactions will continue to be honoured and capital for new investments made available immediately.

Tets Ishikawa, Managing Director of LionFish, said: “We would like to thank RBG Holdings Plc for their support in launching LionFish. Although we had originally envisaged the partnership to last for many years, the lessons we learnt together and RBG’s decision to refocus on professional services has given us the opportunity to find a more suitable, long-term and exciting partner. Tanya and I would like to thank both RBG and Foresight for making this transaction possible.”

Oliver Bates, Senior Private Debt Manager at Foresight, added: “We have followed the litigation finance market for several years and we have always been impressed by LionFish’s model and commercial approach. Having followed it closely over the last couple of years, it was always clear to us that Foresight could provide a stronger platform on which LionFish could fulfil its true potential. We are therefore delighted with this acquisition and are excited and confident that under our ownership, Tets, Tanya and the LionFish team will achieve their business ambitions.”

Tanya Lansky, Managing Director of LionFish, comments: “Foresight’s deep and patient capital base, long-term commitment, and its understanding and support of our model made it stand out. Tets and I would like to thank Foresight for their faith and commitment in us and in our

business. Notwithstanding the situation since last year, we have maintained a strong pipeline which we look forward to leveraging and continuing to grow in this exciting next chapter.”
