umm... the increase is 153% and 134% but otherwise you're correct. Keep in mind that's based on guidance that Mgmt considered as "a minimum". Granted they are currently a little behind schedule with the scrap metal production but can easily catch up in the 2H of the year.
Things look even more interesting next year and beyond. Even without a capacity expansion, I think they can easily do 500M+ in rev and 37M+ in net income in 2011. What's really nice is they have put all the pieces in place this year to secure that future growth, even buying a 19.9% stake of an australian mine to secure a stable affordable source of iron ores.
