"In light of the views expressed by shareholders and any further feedback from shareholders, the executive board is currently considering, if an upgrade to a Prime Standard listing in Frankfurt with MDAX inclusion and a delisting from the London Stock Exchange would be in the best interest of shareholders." Tui said potential advantages of a move were "centralisation of liquidity, providing a clearer investment profile under a single listing, potential benefits to European Union airline ownership and control requirements, potentially enhancing TUI AG's equity profile with an expected prominent position in the MDAX50 and creating efficiencies as well as reducing costs". Shareholders will be asked to vote on the issue at the company's annual meeting on February 13. Under the UK listing rules, a delisting will require shareholder approval of at least a 75% majority of the votes cast.
