USEC is not an "earnings" story. They are currently the high-cost producers of enrichment services BUT they are building the world's most advanced centrifuge enrichment plant. If they complete it, they become low cost producers and can begin winning back market share in the world-wide enrichment market.
In order for USEC to succeed
1) They need a government loan guarentee in order to be able to borrow the money to complete the plant at reasonable rates.
2) SILEX (a competing enrichment technology backed by GE) has to fail.
3) No more Fukushima type disasters hurting the nuclear industry
