To be sure, there are some good business arguments for such a move. For example, a Citi research note points out that the two companies have some overlapping stores that drive down performance at each, and also that the combined company could have greater leverage over suppliers. And KKR may be able to mitigate the high asking price for Saks (SKS) – its current trades are around the same EBITDA multiple paid for Neiman Marcus, so a premium would be rich — by doing sale-leaseback transactions on its some of its underlying real estate assets.

The bigger question may be one of logistics.

Neiman Marcus shareholders originally began laying IPO groundwork last summer, and also appear to have been contemplating a parallel sale process. In other words, Neiman Marcus should be further along than Saks – a timeline issue exacerbated by the fact that it private-to-private deals like Neiman Marcus are usually easier/faster to complete than are public-to-private deals like Saks.

Would KKR make the completion of Saks (or at least shareholder approval) a precondition to closing Neiman Marcus? And, if so, would Neiman’s private equity owners be willing to wait? Or does KKR have a model where Neiman Marcus can produce adequate returns on its own, with Saks serving as gravy?

Not saying that such a two-step can’t be done, but it could be a tricky manuever.
