We have huge opportunities in front of us

August 11, 2014

There’s no question we’ve all been on quite a rollercoaster ride the past few months. As we approached the decision point about our partnership with Alliance Boots, we withstood a storm of speculation and criticism—some of it informed, much of it … less so.

So it’s no surprise that for many team members, the initial reaction to last week’s announcement, along with excitement about sealing the deal, was one of relief. Relief to finally have a measure of certainty about our future.

As the dust has settled, the next reaction is very likely, “What now?”

And that’s where I’d like to focus. We have a lot of work to do, and we have huge opportunities in front of us. So it’s time to tune out all the noise from the media, politicians and the financial markets. They have weighed in, and their reaction has been about what we thought.

So, whether we’re being praised or criticized, we have a job to do.

I personally have never been more excited about our future—and here’s why.

We’re going from being the industry leader in the United States to being a major healthcare and retail player on the global stage. That’s huge—and something we can all point to with great pride.

It will strengthen our long-term financial position, open up big opportunities for us in new markets around the world and give our customers access to an unparalleled portfolio of great brands.

We have a solid integration plan in place and a new leadership team that will be transitioning into their roles as the close of the transaction nears. And we have our Next Chapter plan that will transform the retail model for health and wellbeing, better integrate pharmacy and healthcare to deliver innovative new services and reinvent the pharmaceutical value chain.


Finally, we absolutely must reach new levels of efficiency, accelerating the efforts already underway so we can be nimble enough to seize the many promising global opportunities that await us.

So, as we undertake all this, here’s what I ask of you:

 

    Be open to change. There’s no other way to put it: Constant change is going to be a fact of life (and not just at Walgreens), and we have to do our best to “roll with it” and take advantage of the opportunities that come along.

 

    Be patient. We don’t have all the answers yet, but we’ll do our best to keep you informed every step of the way.

 

    Step up. We’re going to need everyone’s help. In every situation, ask yourself, “What can I be doing personally to help drive our goals along?”

 

    Be bold. In this world, playing it safe is the least safe thing we can do. We have to always be looking for opportunity instead of at the obstacles that limit us.

 

    Be persistent. Keep pressing forward. Focus on the goal and don’t relent.

This is a once-in-a-lifetime opportunity to reshape our industry, and I hope you’re as excited as I am to be a part of it. Now let’s get to work!

Thank you for reading, and be well.

Greg
