The $2.4 billion acquisition of Zulily by Liberty Interactive is a done deal. Englewood, Co.-based Liberty Interactive, which operates QVC, the home-shopping network, said it has purchased and paid for all of Zuily’s remaining shares as of today. Zulily received early regulatory approval last month, putting it on track for a fourth-quarter close. While today is the last day Zulily’s shares will trade publicly, many other things will remain the same, including the Seattle company’s leadership team and headquarters. In addition, Liberty has said it will add Zulily co-founder Mark Vadon, who helped hatch the idea of creating an online shopping destination for moms, to its board.
