Price growth slowed to 2.7% annually in 2017, it said. Micro Focus International PLC (MCRO.LN) tumbled 15% after the software maker said six-month revenue fell on constant-currency terms and a key profit metric, adjusted EBITDA, was lower by 4.1% "as we put operational improvement plans on hold while working on the completion of the HPE Software transaction." The company acquired Hewlett Packard Enterprise Co.'s (HPE) software business for $8.8 billion last year.
