Freshfields Bruckhaus Deringer is advising new client Misys on its £500m IPO, with Kirkland & Ellis and Linklaters also picking up mandates.

Financial software maker Misys was taken private by Vista Equity Partners in 2012 after beating off competing bids from Temenos and CVC Capital Partners.

The decision to list Misys comes after months of speculation regarding Vista’s stake in the company, with the latter thought to have been heading towards a sale rather than flotation.

Freshfields won Misys as a new client after pitching for the work. The team was led by co-head of international capital markets Sarah Murphy and partner Mark Austin.

Meanwhile Kirkland partner Gavin Gordon acted for Misys’ current owners Vista Equity Partners, with the US firm having a longstanding relationship with the private equity house.

Linklaters took the lead role for the banks, with partners John Lane and partner Jason Manketo advising on the finance side.

Misys exists to raise approximately £500m with the listing and expects to debut on the London Stock Exchange next month.
