YouGov CEO Steve Hatch is stepping down following pressure from activist investor Gatemore Capital Management, which has called for the firm to be put up for sale. Gatemore blamed a series of management 'missteps' for a severe share price decline. YouGov shares have fallen around 70% over the last 12 months and are almost 80% below their all-time high. Gatemore wants YouGov to find a buyer and exit London's AIM market at a 'healthy premium'. YouGov said its board had 'mutually agreed' with Hatch that he should step down, and chair Stephen Shakespeare would take his place on an interim basis.
