Hitting this target will of course be a big milestone for TNT, and then setting the next target will have a big impact on the share price, I believe. Revenue is one of the main metrics used for valuations, and reaching the previous target will bring credibility and confidence in their next one, especially given how bold a target $150 million was when they made it (not long ago when current revenue was a mere fraction of it). The lowest target they'd set would be $200 million in 6 or 12 months, and that's a very round figure, approximately equal to our current market cap. Any way you slice it, that's going to look fantastic and lift the market cap. As you rightly say, look at any other company with a $200 million revenue and such a small market cap/relative share price.
