Shares in RTC Group PLC (AIM:RTC), the engineering and technical recruitment firm, more than doubled, adding 102% to 36.5p after it reported an increase in profits and revenues in the first half.
Revenue from continuing operations jumped 33% to £45.6mln, while contracted revenues grew to £43mln from £32.1mln, with an order book in excess of £200mln.
RTC, which works with Network Rail, also swung back into a profit of £1mln, after a first-half loss last year of £400,000.
"I am pleased to report that, whilst industrial action remains disappointingly prevalent, albeit with less impact, our Rail business is back trading strongly and in line with our expectations. Our other businesses are also showing strong recovery and have progressed well as anticipated," said chairman Bill Douie.
