Octopus Investments and Clydesdale bank also supported the MBO, which saw shareholders including original MBO backer Finance Wales sell their stakes.
Vista, which was launched in 1995, has growth to become an organisation with a turnover of £14m, and supports retailers including Superdrug, Lloyds Pharmacy and BHS.
WestBridge partner and CIO Sandy Smart said, “Vista has progressed very well since the original management buyout and the recent upturn in economic activity will provide excellent opportunities for further growth.
“We are delighted to be able to support the vision of the management team and its ambitious plans for the future.
Finance Wales portfolio development manager John Mihell added, “Vista is a great Welsh success story and its success demonstrates the difference Finance Wales’ backing can make.
“ With a 4.5-times return on our investment, this is our largest, most profitable exit to date and we look forward to helping create more success stories like Vista in future.”
