The firm expects underlying profit for 2011 to reach between £155m and £159m, which would take it to growth of up to 57.9 per cent. It also said it should earn £11m in performance fees for the second half of the year.
Henderson, which manages more than £65bn in client assets, has focused on attracting more money to higher-margin products. It recently signed up Real Madrid and former Chelsea boss Jose Mourinho – the self-styled “special one” – to help promote its brand against a backdrop of sluggish business and flatlining fund fees.
Earlier this year it said it was winding down its low-fee earning businesses to focus on more lucrative active fund management. Separately it is mounting a vigorous defence against legal claims from a group of pension funds over the handling of its investment in construction firm John Laing.
