You can work out the D&A yourself - both EBITDA and EBIT are given in the ann. Maybe you can get a gauge on the age of the plant from that number, but I feel it's unlikely it's too old as miners and gas companies would be major clients and they don't tend to like old equipment - it's a pain to get certified for use on site.

SSH have a tendency to trumpet their revenue and EBITDA figures in their presentations and bury the NPAT in the accounts. I suspect that's the main reason they use pro forma EBITDA here, to gel the numbers with the underlying business.
