Military goods producer Chemring has seen a 5% increase in trade during the four months to the end of February despite deliveries being hit by extreme winter weather.

According to the company, adverse weather conditions in the first few weeks of 2010 disrupted production in most of its US and UK subsidiaries, which affected deliveries in January and February.

The company, which produces countermeasures products that help fighter planes avoid missile attacks, said the impact of slower deliveries was expected to be recovered in the next two to three months, according to Reuters.

According to Thomson Reuters I/B/E/S poll, market expectations for 2010 pretax profit range from between £122m and £130m, with the consensus at £125.22m.
