Medibank has failed to win a new contract to provide healthcare services to the Australian Defence Force.
Shares in Medibank, which was government-owned until its 2014 privatisation, were halted on Monday after the ADF told the insurer it would not extend its current arrangement with Medibank's Garrison Health Services past June next year.
Medibank last year made an operating profit of about $30 million from the ADF contract, which it has held for six years.
