Jan 11 (Reuters) ? British defence contractor Ultra Electronics , which has warned of lower defence orders in the country, said on Thursday it had significant exposure to a rising U.S. defence budget, and had seen growing demand for advanced technologies.

The company, which makes military electronics for land, air and sea operations, also said it expects to have modest progress in 2018 underlying revenue and operating profit on a constant currency basis. …

Shares of Ultra Electronice were up 13 percent at 1428 pence in early trading, making it the biggest percentage gainer on the FTSE Midcap Index Ultra Electronics said it had begun the new year with an order cover on expected revenue of about 62 percent, higher than about 56 percent in 2017.

“The board is confident that Ultra has sustainable operating trading momentum with a significant number of recent long-term contract wins,” said Douglas Caster, Executive Chairman.

The company said order intake for the year ended Dec. 31, 2017 was about 900 million pounds ($1.21 billion), adding it would recommend a final dividend of 35 pence per share.

The company said the search for a new chief executive was underway, after its last CEO quit in November as Britain’s government scaled back business with the defence contractor. …

Funding pressure on the Ministry of Defence has forced it to pause, cancel or delay several programmes and “within the last few weeks a number of our UK orders budgeted for 2017 have been affected,” Ultra Electronics said in November.

Ultra Electronics’ new chief will be looking to tap U.S. President Donald Trump’s promised $700 billion in defence spending. The U.S. accounts for 50 percent of the company’s revenue, while UK accounts for 24 percent.
