## About

Souter Investments was established in 2008 by Sir Brian Souter after he built Stagecoach Group into a major UK transport operator. His sister Ann Gloag co-founded Stagecoach. The office maintains its headquarters in Edinburgh and invests the family's capital on a long-term basis. The firm concentrates on private equity buyouts and growth investments in unquoted companies. It also holds positions in listed securities, real estate, and infrastructure. Asset classes include direct co-investments, SPVs, and select fund commitments. Confirmed holdings include Acteon Group, McAvoy, Likezero, Tracerco, and Premier Hytemp. The portfolio spans the UK, New Zealand, Europe, and the Middle East. Souter Investments employs a compact team led by Sir Brian Souter and Chairman Andy Macfie. It maintains no disclosed additional offices. The Souter Charitable Trust receives substantial distributions from investment activity. In December 2025 the firm released its H2 Newsletter covering recent transactions and portfolio updates. The office's structure ties investment decisions directly to the founding family without external capital or limited-partner obligations. This alignment allows extended holding periods and co-investment alongside partners such as Duke Street and Sullivan Street Partners on carve-outs and management buyouts.
