SYT General, page-938

You've only included H1 in that revenue figure. Their FY16 revenue was $93m and they're on track to easily exceed $100m revenue for FY17.

Also, you have to compare revenue to market cap - not share price, as you need to adjust for the vastly different number of shares on issue for each company.

ALU is trading at around 10-11x revenue atm ($1.1b / $100m). SYT is at 300x revenue ($75m / $250k). Obviously at different stages and a degree of expectation being priced-in to SYT making a go of things.
