I think in 2018 they made around the same EBITDA they're forecasting for this year and that led to a 2c dividend.
They did mention that they were holding off paying a dividend because of the TCIG offer. If they're confident of their forecast they could do 1c now and 1c in December.
I think it's likely we'd be looking at around the 2c mark though once the year is out and if we can avoid the TER takeover.
