Glasgow-based sausage skin and collagen products firm Devro said its revenue rose 11% to £125.2 million in the six months to June 30 but underlying profit before tax fell slightly to £13.1 million.

Devro said it enjoyed particularly strong volume growth in China, South East Asia and Russia, with an expected volume decline in Latin America.

Devro CEO Peter Page said: “Devro has made good progress with its principal objectives of growing revenue, volumes and market share in a range of markets, whilst reducing unit costs in operations. 

“The Devro 100 programme to accelerate achievement of these objectives has progressed well during the first half of 2017. 

“New products will be introduced during H2 as planned.

“The board’s expectations for the full year remain unchanged and the business continues to generate strong cash flow from the underlying operations, which will enable net debt covenant ratios to be returned to historic levels over time.“
