Shares of Diebold (DBD) are down 8% so far this year, but the company’s CEO Andreas Mattes said things are already looking up for 2016 when the ATM manufacturer completes its $1.8 billion acquisition of German-based Wincor Nixdorf. ‘We are on a journey to become a services led software enabled company and this going to propel us to a much bigger level,’ said Mattes. The new company will be called Diebold Nixdorf and it will boast the largest installed base in the world with nearly 1 million bank-owned ATMs. According to Diebold, approximately 1 in 3 cash withdrawals made globally will be made at one of the combined company’s ATMs. Diebold Nixdorf will also boast one of the largest services organization in the industry with more than 15,000 professionals globally. Mattes said he expects the transaction, which will likely be completed in full by the middle of next year, to yield approximately $160 million of annual cost synergies.

Transcript of The Street Interview with Diebold, Incorporated Chief Executive Officer, Andreas Mattes (December 10, 2015)

GREGG GREENBERG: Andreas Mattes, shares of Diebold, they’re down on 8% so far this year, but it’s been fairly range bound in between 30 and 36. But the big news about your company came last month; you’re buying Windcor Nixdorf for 1.8 billion. So how will this transform your company? What will you look like in 2016?

ANDREAS MATTES: We’re on a journey to become a services led software enabled company, and this is just going to propel us to a much bigger level. Think about it this way, we’re basically doubling our installed base. We’re going to have about a million ATM machines installed around the globe which we’re going to service, which we’re going to provide value added services for, which we’re going to provide software for. So it will take us a big step forward to being the premier service provider in the ATM space.


GREGG GREENBERG: And you believe Diebold and Nixdorf when it finally becomes complete, and this is a German company. So why don’t you tell us what you’re going to look like in Europe.

ANDREAS MATTES: If you take a look at our revenue, it’s going to be very evenly distributed; 40% Americas, 40% Europe, and 40% Asia Pac. And in Europe, we’re going to be a major force, which is very attractive because the whole theme in our industry right now is called branch automation, substitution of labor in the branches through the machines. Needless to say that trend is the most prevalent where labor is the most expensive, which happens to be in Europe. So being a powerhouse in Europe is an incredible important springboard for us going forward.

GREGG GREENBERG: And what about in the Asia-Pacific region?

ANDREAS MATTES: The cool thing is both companies fit together like two pieces of a puzzle. We’re so complimentary. That also holds true for Asia. They are strong in the countries where we weren’t that strong like Malaysia and Indonesia. We’re really strong in the markets they’re not strong like India, the Philippines, Thailand. So it’ll broaden our Asian footprint.

GREGG GREENBERG: And will it make you stronger in the big battle against NCR? I guess you’ll be bigger than them once this is through.

ANDREAS MATTES: It’s just going to make us the premier services and software company in our industry. It’s going to give us a great chance in our competitive positioning in the market, but most importantly it will provide a very unique position against all the Asian players that are coming into our business who are way more hardware centric than, than we are, and who do not appreciate the services and software we’re offering.

GREGG GREENBERG: And people are worried about security now, this is a very big issue, especially when it comes to their finances. They’re seeing lots of hackings worldwide. People are worried about ATMs and you’re coming out with new products to provide security as well as new technologies. Irving and Janis, these are new –- your new technologies. Can you tell me about Irving and Janis?

ANDREAS MATTES: They’re a great couple. There are two innovations that we’ve done with city labs, and we just showcased them in Las Vegas at Money 20/20. Irving is the first ATM in the world where you have iris recognition, where you can walk up to the machine with your cell phone, use the NFC code in your cell phone, connect through the cell phone, pre-stage everything, and you will not have a keyboard. You don’t even have a screen anymore. It’s all done on your mobile and you use biometrics. It’s 100% secure, no skimming possible, and much faster and much more convenient.

Janis — similar approach; again combining the mobile with a machine, but think about the machine now having a scanning table; it’s about a 21-inch monitor that you have at the machine. So if you want to deposit checks you need to scan a driver’s license. You need to sign a legal document. You just put them on the table like you would in front of a counter. The machine scans these, reads them, and automatically transforms the function that you need to do.


GREGG GREENBERG: How dependent are you on banks adding branches for you to expand? What’s your relationship with the banking industry?

ANDREAS MATTES: Well, the banking industry is our main customer. But the important thing that we need is touch points of the banks with their customers, and any consumer that you ask why they bank with a bank that they’re with it’s proximity to the home or proximity to the office. Can the banks afford all their branches? No, branches will probably go down, but touch points will go up. So you will have more machines in retail stores, at the corner, they need to leave something behind in the neighborhood and every time you read about a branch closure in the papers, literally on the flipside of that press release is an order to a company like ourselves for more high-end technology that will enable the banks to have a cost effective footprint in the neighborhood.

GREGG GREENBERG: All right. Well, thanks Andreas Mattes.

ANDREAS MATTES: Thank you very much.

GREGG GREENBERG: Thank you for watching the street.
