Mr. Oz, the Harbin contract stated a deposit. You may be able to extrapolate the new contract value from the admission document. Add to that existing revenue figures from last year. And discount organic growth. That's the fundamental basis. And at 18p, on that reasoning, its rather cheap. The placing proceeds, very small of course, were used to establish a sales base in the US/UK (to be confirmed on Jan update). There's four major businesses in this company, again the admission document will help. The prospect of more contract wins in China is immense, given that the Harbin city contract has been won. Add to that the previously quoted US article that the US wants all its lights to be replaced with LED by the 2010's.
In terms of your share price, consider the shares in issue (just 5 million) and the impact of a positive trading statement. It's got a very large safety margin in profits at this price anyway.
