Our performance underpins our sector-leading dividend policy of 4% growth per annum above RPI inflation to 2020," Pennon said in a statement.Statutory profits after tax increased 6.1% to £72.9m.Following the results, analysts at HSBC bumped up their target price on the shares from 910p to 940p, telling clients that: "we maintain our Buy rating as we believe the stock combines regulatory stability and growth opportunities."The interim dividend per share was increased 6% to 11.09p.
