Meanwhile, Elster Water remained on track for annual profit growth.Melorse's Brush business was consistent with expectations that trade would be sluggish in the first half, before accelerating in the latter part of the year, due to a slowdown in turbo-generator demand and difficult market conditions across the oil and gas sector."Overall, trading in the Period allows the board to be confident about the performance of Melrose this year. The board continues to be keen on finding the next acquisition," a company spokesperson said.Melrose was trading 1.8pm or 0.69% higher at 262p as of 12:15.
