SHI achieved "another key milestone" in its UK and European expansion in November 2022 when it opened a 38,000 sqft integration centre in South Yorkshire (having first touched down in the UK in 1998). Based on market sources, CRN estimates that the Microsoft, Cisco, Dell, AWS and HP partner turns over roughly $600m in EMEA and is growing at around 35 per cent. The UK is thought to generate about 40 per cent of that total. Globally, New Jersey-based SHI turns over $12.1bn and employs 5,000 staff.
