Language translation service provider SDL warned on profits as it struggled to close software deals.
"If these deals are not closed, adjusted EBITA for 2017 on a like-for-like basis will be below current market expectations," the company said.
In addition, SDL said it experienced a faster than forecast shift from perpetual licence sales to software-as-a-service sales. This resulted in higher costs, with revenues deferred into future years.
