Jeffrovich, As is generally the case in short attacks there is some merit in Cohodes assertions - but also, as is typically the case, he throws in a bunch of totally wild unfounded allegations.
The core issue is the sustainability of the dividends and EIF's use of FCF less maintenance capex (but not growth capex) as the denominator in their payout ratio calculation.

In Q2 and H1 2017 EIF reports payout ratios of 75% and 115% respectively. 
In the same periods their FCF - maintenance capex was $21.8 million and $28.2 million respectively. However, growth capex was $33.1 million and $98.8 million respectively. So if you take that into account a 'hard' measure of FCF would be negative. That's the nub of the concern. 
If they can continue to sell equity as required (and as they did earlier this year) fine. But this avenue may now be constrained. In that case the fallback option is to prune/eliminate growth capital - or increase debt.
