nsom, re: BWOW/BWOWW - with a forward PE in the low single-digits, a gov't still spending bucks on heavy construction infrastructure, a recent contract win in the U.S., and BWOW being the only player in their niche, I'd say that the future is pretty exciting.
The warrants have some non-trivial intrinsic here (common ~7.25; warrants 1.75 with a $5 strike).
Solid DD combined with timeliness and conviction is a recipe for profits.
