Beesley will take up the role of CEO at a turbulent time for Jupiter, which struggled with severe outflows of £1.6bn in the first quarter of the year.
Market commentators have said the outflows make it vulnerable to a takeover, despite Formica saying earlier this year that Jupiter does not see itself being part of the current wave of consolidation in the sector.
The outflows are focussed mainly in the group’s European and UK equity funds, but also in the Merian funds.
A few weeks prior to Formica's announcement, former board member Jon Little criticised the fund house, saying it has "lost its way" and needs to change its management and strategy.
