RPS Group reported a 'robust' performance in 2013, prompting a 15 per cent increase in the dividend for investors in the oil and gas consultancy.

RPS remains a well respected company operating in a global marketplace. "Our range of activities and geographic spread will enable us to generate further growth as the global recovery develops further. We continued to deliver our strategy by investing in a number of high quality acquisitions in attractive markets. The board is confident this will enable us to perform well in 2014."Broker Jefferies reiterated its 'buy' rating on the stock, saying: "Whilst FX may result in low to mid-single digit 2014 consensus earnings per share downgrades, given recent share price weakness [...] we remain buyers."
