 Premier Inn owner Whitbread PLCs LSE:WTB third quarter trading update next Thursday will see shareholders checking in to try and find comfort over the issues which have caused shares to slip by 11 over the last 12 months and over 30 since before the pandemic. The shares have been weighed down by a slowing economy in its key UK and German markets, said analysts at AJ Bell, along with the squeeze on consumer incomes as a result of soaring inflation and forecast downgrades as a result of higher energy, staff and input costs.
