UBS Warburg raised £19.7m (€32m) for Marlborough Stirling, the UK-based software company, just seven months after it led the flotation of the first information technology firm to list on the London Stock Exchange this year.

The bank completed the sale of 12.3 million shares on Tuesday at 160p, a 3.03% discount to the previous day's closing price. The disposal was made by Apax Partners, which acquired its holding following Marlborough Stirling's recent acquisition of Exchange FS, a UK electronic trading platform in which the global private equity house had a stake. UBS said shares were sold to UK, European and US investors. Marlborough Stirling shares are trading at 168p on Wednesday, up 20% from its issue price in April when the firm raised £66m in an initial public offering.
