Leumi ABL backs Mthree–Peregrine merger with £10M facility

Leumi ABL has provided a £10 million asset-based lending facility to support the merger of Mthree and Peregrine International Limited, both portfolio companies of UK private equity firm Inspirit Capital. The deal combines Mthree's private sector recruitment focus with Peregrine's public sector operations in the hire-train-deploy market. The merger aims to deliver increased scale, strengthen management and unlock cross-selling opportunities across both sectors. This marks Leumi ABL's third financing arrangement with Inspirit portfolio companies, following its backing of @Spaldings Ltd's acquisition in June 2023. The combined group operates across the UK and US. Inspirit Capital highlighted asset-based lending's flexibility and scalability for PE-backed businesses, whilst Leumi ABL emphasised its expertise in cross-border transactions and understanding of private equity requirements.
