Do a 10% equity offering and buy them out. Top line would rise by 50% (or more as OSTK has no international presence), bottom line would expand significantly. The risk reward makes a lot of sense as they trade at 6X multiple on sales to OSTK. Its a good strategic fit as they are looking to compete against AMZN with their goods segment and OSTK has experience with operating multiple distribution hubs.
OSTK valuation is compelling given it's about 20% of the valuation of GRPN. GRPN is trying to push into restaurant reservations and hotel stuff but it still gets 100% of their revenues from retail sales so the justification of it trading at 5.5X higher price to sales of OSTK is a bit of a stretch.
