It has been reported that this drop in sales is equivalent to approximately £100m. However the business added that it will be able to make up some of the revenue in the third quarter.
RB expects like for like growth for the full year to be up 2%, down from a previously projected 3%.
The effects of last week’s global attack, which also hit WPP, have still not been fully resolved but RB said that the problem has been "materially contained".
In a statement, it said: "The attack did disrupt the company’s ability to manufacture and distribute products to customers in multiple markets across the RB Group.
"Consequently, we were unable to ship and invoice some orders to customers prior to the close of the quarter. Some of our factories are currently still not operating normally but plans are in place to return to full operation."
