The ACS-Xerox Deal: Was it a Smart Move?

September 30th, 2009

Since the news became public on Monday, hundreds of media, analysts and bloggers have had much to say about Xerox’s intent to acquire ACS. With all of the insightful banter, candid commentary and strong opinions being shared – both good and bad – I figured it was time to officially join the conversation.

From my perspective, there is only one question that everyone is trying to answer: Was it a smart move? For those of you that answered “yes” to that question, you can stop reading now. I’m going to spend the rest of this post trying to convince the skeptics.

Document management and beyond: through the ACS acquisition, we are hitting the “sweet spot” of fulfilling our vision of owning all aspects of document management, while preparing for tomorrow’s growth. In a maturing enterprise technology market, customers increasingly want to outsource the purchase and management of complicated systems, and to offload administrative tasks. By purchasing ACS, we can handle more for our customers.

We will be able to provide customers with a global delivery network, significantly scale our Business Process Outsourcing capabilities and differentiate Xerox in the marketplace. Please remember, we are primarily going after the BPO space, that layer where real business is getting done.

As the Wall Street Journal rightly pointed out today, “Xerox hopes to marry its document technologies with ACS’s paper-heavy processing work. It can use its overseas presence to expand ACS. Xerox also is paying a reasonable price of about 13.5 times consensus fiscal 2010 earnings, well below the 29 times that Dell is paying for Perot. Investors may be overreacting.”

Investors overreacting: there are comments out there saying we are grasping for revenue growth. Already, Xerox continues to lead in the fastest growing segments of our market, color adoption, digital production printing and managed print services. We are not desperate for growth – we have made a strategic decision to invest in the future of our company.

In an interview with Fortune, Xerox CEO Ursula Burns tells investors, “We’re actually scaling our services business and scaling our BPO in a very effective way to respond to changes in the marketplace.”

The ACS acquisition provides us instant scale in the BPO arena. Analysts say the current BPO market is about $130 – $150 billion, and growing 5 to 10 percent. With the Xerox/ACS combination, the total market opportunity is more like $500 Billion.

And shareholders who would like to have seen Xerox buy back stock instead of incurring additional debt? This new company creates a $22 Billion company with $17 Billion in recurring revenue, in our estimation. It brings our services revenue up from $3.5 Billion to approximately $10 Billion.

So, was it a smart move? My answer is a resounding YES!
