Informa's first-half performance is expected to be hurt by the rescheduling of events in the Middle East, Citi analysts write. They expect B2B Live Events underlying revenue growth of 7.5% for the half year compared with 7.6% for the first five months. The London-listed events and academic-publishing group is due to report half-year earnings on July 30. It said on June 18 that it was returning to B2B growth in markets directly hurt by the conflict in the Middle East. Events in the region are expected to go ahead, but questions remain over how much growth will be affected, the analysts say. Shares are down 1% at 906.50 pence. Citi has a buy rating on the stock and 990 pence target price. (ian.walker@wsj.com)
