This is an excerpt from the latest press release. I like the way it is "almost 49%" - that's almost 50% but not quite as much.
“With these contracts in hand, Surna is off to a promising start in 2019. If fully realized, these contracts alone would represent almost 49% of our full year 2018 revenue..."
The math implies that 2018 revenue ($9.582 mil) plus the new contracts ($4.7 mil) equates to projected revenue in 2019 of $14.282 mil.
