In some European countries, public companies issue trading updates for the first and third quarter, but only provide actual revenue, expense and earnings numbers for the half and year.

 The company said the unit's operating profit margin declined, owing to the inclusion of Tagetik, which was acquired in April 2017, and increased investment in product development. WK also said software for professionals and corporates “saw sustained high single-digit organic growth.”

The drop in the value of the U.S. dollar against the euro took a toll on overall revenue, which fell 8 percent from last year’s first quarter. However, the top line was up 2 percent in constant currencies and 4 percent organically. 

 “We are making progress on fostering the development of recently acquired businesses and have successfully completed several non-core disposals in the first quarter,” CEO Nancy McKinstry said in a prepared statement.
