E-commerce at all of our banners have been very, very strong,” Baker said. HBC operates Hudson’s Bay in Canada, Saks Off 5th, as well as Saks Fifth Avenue. It also has extensive real estate holdings, including real estate joint ventures.

With the split-up, Marc Metrick, who has been president and CEO of Saks Fifth Avenue, becomes CEO of the Saks e-commerce business, and a member of the new company’s board of directors.

Larry Bruce has become president of the SFA stores. Bruce has been with Saks Fifth Avenue for nearly 20 years, including the past eight as director of stores.

Sebastian Gunningham will join the Saks board of directors and serve as an adviser. Gunningham was previously an executive at Amazon, leading its marketplace expansion among other large technology and operational divisions at the company. Earlier, he held executive roles at Apple and Oracle.

HBC said SFA and Saks will work in conjunction to continue delivering “a seamless customer experience” and spelled out some of the division of functions. The Saks e-commerce company will lead marketing and merchandising across both Saks and SFA. Saks will retain ownership and control of the Saks Fifth Avenue intellectual property, including the brand and visual identity.

The SFA stores company will fulfill the physical functions of Saks, such as buy online, pick up in-store; exchanges; returns, and alterations.

This is disruptive from a business model and a partnership standpoint. We are breaking the mold,” Metrick told WWD. “This will allow both channels to be independent from an investment standpoint, to grow, and to continue to provide amazing customer experiences. The consumer experience is going to improve and consumers won’t realize there are two separate entities delivering that experience. They will view it as the Saks Fifth Avenue ecosystem, just as they do today.”

Metrick also said that in his new role, he won’t be removed from the stores and that along with Tracy Margolies, chief merchant, they will be responsible for the assortments in both channels and “the look and feel” of the brand presentations.

Integrating a marketplace format into Saks’ e-commerce site, Metrick said, enables saksfifthavenue.comto go wider in our offer with our existing brands, and go deeper. We can certainly also stretch into categories we don’t sell and bring far more brands on the website. But it’s all going to be luxury. That’s very important. And we will remain in fashion. We do not intend to be a marketplace for spearfishing. It’s always going to be Saks, with a point of view. It will know you as a consumer, giving a personalized experience.”

Luxury online is on fire,” Metrick said. “We know we can explode growth and really start to move the top-line at a much more rapid pace — starting today. The Saks dot-com business is profitable. Right now, we can invest for growth. Twenty years ago, when luxury on the internet started to get grounded, stores like us and some of our competitors couldn’t get into the game with the right level of investment. You had to make choices. To that end it opened up space for others to get into the market. As luxury e-commerce is about to triple in the next few years, we are not going to miss out on the opportunity.”

Saks Fifth Avenue is an unbelievable brand with a great customer base. If you ask anyone on the street, 90 percent know the brand, but the site experience is not where it needs to be,” said Deven Parekh, managing director of Insight Partners. Historically, he said Hudson Bay Co. had to run the Saks dot-com business on a constrained budget. “They’ve had other financial obligations and debt. Now Saks will have a well-capitalized balance sheet. The only debt is revolving credit for inventory.”
