An update said: "We continue to make good progress on our cost initiatives and are on track to deliver £18m of net savings in the year to March 2017.
"We are also investing to drive the long-term growth of the business, appointing new Presidents for both RS and Allied and significantly strengthening the leadership teams in Innovation, DesignSpark and IT.
"We continue to expect FY 2017 revenue and profits to see a significant benefit from foreign exchange and additional trading days.
"As previously guided in FY 2018 we expect to see an adverse impact on revenues and profits from fewer trading days compared with FY 2017."
