Henderson Group - 1Q17 Trading Update & Dividend

First Quarter 2017 Trading Statement

First Quarter 2017 Extraordinary Dividend

19 April 2017

Henderson Group plc ("Henderson") publishes its first quarter 2017 trading statement today. The comments below refer to the period 1 January 2017 to 31 March 2017 ("the period") unless otherwise stated.

Key points

· Assets under management ("AUM") at 31 March 2017 increased to £103.1bn (31 December 2016: £101.0bn), driven by positive investment performance and FX gains

· Net outflow of £1.4bn from Retail and £0.4bn from Institutional

· Long-term investment performance remained strong, with 73% of funds outperforming over three years1

· First quarter 2017 extraordinary dividend of 1.85p per share.

Andrew Formica, Chief Executive of Henderson, said: "While Retail client outflows continued, we saw an improvement in client sentiment and flows as we moved towards the end of the quarter. Aside from the one-off outflows that resulted from the merger-related restructuring of our Global Equities team, our Institutional business continues to see steady growth, with a healthy number of mandates funding since quarter end.

"We have made substantial progress in preparation for our proposed merger with Janus Capital Group. It is an exciting time as momentum builds towards the launch of Janus Henderson Investors, which will enable us to significantly increase our distribution reach and investment capabilities. We continue to be pleased with the supportive response from clients and await shareholder approval on 26 April."

AUM and flows

Total AUM increased in the period to £103.1bn at 31 March 2017 (31 December 2016: £101.0bn), driven by positive investment performance and FX gains.

Retail net outflows were £1.4bn for the quarter, with 85% of the outflow occurring in the first two months. Against an improving economic and European political backdrop, Retail client sentiment is showing encouraging signs of improvement with outflows tapering significantly through March. This positive trend continued into April.

UK Retail saw a net outflow of £0.2bn in the first quarter, with continued client demand for Henderson UK Absolute Return and growing interest in Emerging Markets offset by modest outflows from the Property fund.

In the US Mutual fund range, continued demand for income led to net inflows to Global Equity Income. This was counterbalanced by outflows from International Opportunities and European Focus reflecting a continuation of the trend observed in the latter half of 2016, with clients reducing exposure to non-US assets. Net outflows were £0.2bn, an improvement on previous periods.

SICAVs in Continental Europe and Latin America saw an outflow of £1.0bn as clients continued to reduce their exposure to European assets. However, outflows slowed towards the end of the quarter as concerns over the political landscape in Europe subsided.

The Australian Retail business made a modestly positive contribution to net flows in the first quarter - its sixth consecutive quarter of positive net flows.

Institutional net outflows were £0.4bn. Mandate wins which funded in the first quarter were offset by one-off redemptions following the merger-related restructure of Henderson's Global Equities offering. Further new mandates, which funded in early April, reversed this position. After these, there remains a healthy pipeline of unfunded mandate wins.

Henderson's Institutional business continues to diversify both in terms of asset class and geography. Support from Institutional clients remains encouraging, as the investments made in improving Henderson's Institutional offering continue to bear fruit.

Investment performance¹

Long-term investment performance remained strong, with 73% of funds outperforming the relevant benchmark over three years (December 2016: 77%). Over one year, 54% of funds outperformed (December 2016: 50%).

1. Representing 99% of assets under management as at 31 March 2017.
