Building materials company Kingspan has posted a 19% increase in revenue for the year ending 31 January 2018, according to preliminary figures.

The results show a revenue of €4.4 billion for the Co Cavan company, with a trading profit of €445 million.

The company reported a strong performance in the Americas and continental Europe for insulated panel sales, which were up 21% for the year.

In a statement, Kingspan said it was the first time earnings before interest, tax, depreciation and amortisation exceeded €500m.

They said that with the exception of the UK market, most markets ended the year strongly with order banks well positioned for the start of 2019.

However, they added that the UK market "is relatively stable for Kingspan despite the backdrop".

Chief Executive Gene Murtagh said 2018 "was a year of strong growth for Kingspan".

He said while the outlook for the future is positive, they "remain mindful of challenges to growth, particularly the continuing uncertainty in the UK".

Mr Murtagh added that geographical diversification - helped by acquisitions last year in Latin America, Southern Europe and India - means the company is "well placed to continue to deliver long-term returns to shareholders".

Meanwhile in an interview on RTÉ's Morning Ireland, Mr Murtagh said he was waiting for clarity before taking action on Brexit.

Shares in Kingspan are up 2.1 percent to €39.76 following the announcement.
