Check the latest ann by them.
It's as they don't have the variable rent known at this time. so I assume it will be much higher.
When they IPO'd they said 8c for the year, and I am guessing they wanted to announce that sooner rather than later be known for not keeping their word. From the announcement:
Due to the variable rent component of the rent received by VTH under its Leases with Costa GroupHoldings Limited (ASX:CGC), VTH is unable at this time to accurately determine the amount of thedistribution for the period ending 30 June 2019 until it is in receipt of the calculation of the final variablerent figures under the terms of the leases.
