13018 Town Hall Focuses on OfficeMax Merger

NARRATOR VOICEOVER: At a special Town Hall, Office Depot Chairman & CEO, Neil Austrian, explained merging with OfficeMax gives the joint company necessary capital.

NEIL AUSTRIAN: For us to make any big bets, let alone small bets, we’ve really been handicapped here—given the loss of revenue from 16-billion down to 11-billion dollars over the past four or five years. Putting the two businesses together results in a business that has $18 billion in revenue and gives us the financial flexibility to really transform the business.

NARRATOR VOICEOVER: A business facing increased competition from expanding retail and online office suppliers, making this merger a good bet to receive FTC approval.

NEIL AUSTRIAN: And in talking with our anti-trust attorneys, they see the marketplace differently today than it was seen in 1997. So it has changed, at the same time we’ve gotta be prepared that it doesn’t happen.

NARRATOR VOICEOVER: Lessons were learned during the 1997 Staples merger, when Office Depot shared too much with its rival, leading to competitive consequences when the deal fell through.

NEIL AUSTRIAN: Which is why we didn’t name a CEO of the combined company, which is why we didn’t pick a name. Which is why we didn’t pick a location. Because at the end of the day, while I’m very optimistic it’ll be approved, we can’t take the chance that the same thing happens in 2013 that happened in 1997.

NARRATOR VOICEOVER: So for now, it’s business as usual—and Office Depot needs all its associate to continue executing the company strategy.


NEIL AUSTRIAN: And I’d really say keep your head down. Keep doing what you’re doing, and you’ll be successful. But none of us—whether we had this merger or didn’t have this merger—is guaranteed anything. And I don’t wanna get up here and say everybody’s gonna have a job for life, cause that’s not the case. But there are no major layoffs planned.

NARRATOR VOICEOVER: In fact, there’s an increased focus on building a stronger company, that can better compete in a constantly changing world.

NEIL AUSTRIAN: I mean, we’ve proven we can run a business in really crummy times. And they’ve been pretty bad. So I think in terms of putting these two businesses together, there has to be a new vision in terms of what can be. And I think that we’ve got one shot, and a real opportunity to take advantage of that.
