In its Interim Management Statement released earlier this week, Speedy Hire Plc said that trading for the period from 1 October 2011 to 14 February 2012 overall has been in line with the Board's expectations.
Group underlying revenues for the third quarter (Oct - Dec) were up 7.6% against the prior year with the focus on self help measures to drive operational efficiency delivering further improvement in profitability. The Group expects to have opened a further 3 superstores by the end of February.
Speedy's second half is always influenced by the Christmas period when the weather and holidays cause activity for many of its clients to be reduced. Whilst in January the initial speed of recovery following the Christmas period was slower than expected as the mild weather resulted in lower revenues from heating and drying equipment, subsequent trading has benefited from the recent bout of cold weather, together with improved revenues from non-weather related activity.
The Group has maintained its focus on the regulated industries and private sector investment markets of water, waste, energy and transport. Speedy said it is making steady progress despite the challenging market conditions and uncertain economic outlook and the Board remains confident of meeting its expectations for the financial year.
