Shares in Rosebank Industries PLC (AIM:ROSE) rose 8% to 322.4 pence after the turnaround specialist upgraded its full-year guidance following two recent acquisitions.
The company, founded by Melrose veteran Simon Peckham to buy, improve and sell underperforming industrial businesses, said adjusted operating profit and earnings per share would beat consensus for 2026.
It also signalled confidence that the group would keep outperforming into 2027.
The upgrade was driven by strong early progress at MW Components and CPM, acquired in May, alongside continued improvement at Electrical Components International.
MW Components, a maker of fasteners, springs and precision parts, grew ahead of pre-acquisition expectations across all three of its businesses.
Rosebank has moved quickly to cut costs, closing the unit's head office for annual savings of at least $15 million and announcing three factory closures.
It has also approved $30 million of capital spending to boost capacity and efficiency.
At CPM, which supplies processing machinery and aftermarket parts, aftermarket revenue grew about 7% in the half, and the group has bought its UK and Ireland distributor for €26 million.
A new chief executive will join CPM on 1 October.
Electrical Components International traded in line, with its higher-margin electrification and industrial arm growing 9%, offsetting weakness in appliances.
Peckham said all three businesses were improving as a result of actions taken since acquisition.
He acknowledged well-understood headwinds in the appliance market but said he remained confident in the plans for each business.
Interim results are due on 3 September.
