The need for expanded mass transit in ever-growing mega-cities provides a strong tailwind for the non-defense portion of CUB’s business (see, for instance, #msg-57987139).
#msg-66355098 has a dated pie chart of CUB’s revenue sources, but it’s still fairly accurate.
I owned CUB from 2010-2012 and sold when the stock popped on the death of the founding CEO (#msg-76957330), which led investors to think a buyout was in the cards.
The buyout never happened and the share price is now about 20% lower than when I originally bought the stock six years ago. CUB may be worth another look.
