Notice Regarding NTT Communications’ Planned Stock Acquisition of Lux e-shelter 1 S.a.r.l.

NTT Communications Corporation (“NTT Com”), a subsidiary of Nippon Telegraph and Telephone Corporation (“NTT”), has announced today that it entered into a stock purchase agreement with the shareholders of Lux e-shelter 1 S.a.r.l. (“e-shelter,” headquartered in Luxembourg), the largest provider of data center services in Germany, to acquire 86.7% of e-shelter’s outstanding shares. For more details, please see the attached press release by NTT Com.

This acquisition will not have a material impact on NTT’s consolidated results of operations.

TOKYO, Japan, Luxembourg and Germany — March 3, 2015 — NTT Communications Corporation (NTT Com), the ICT solutions and international communications business within NTT (NYSE: NTT), e-shelter, the top operator of data center services in Germany, and ABRY Partners, a private equity investment firm, jointly announced that NTT Com will acquire 86.7% of e-shelter’s issued shares. The acquisition will vault the NTT Com group into the no. 3 position for data center space in Europe.

e-shelter is currently managing nearly 90,000 square meters of data center space in four major cities in Germany, as well as Zurich, Switzerland and Vienna, Austria. One of its main facilities, Campus Frankfurt 1, Europe’s largest data center with some 60,000 square meters of data center space, comprises five free-standing buildings constructed specifically as data centers.

The acquisition will further strengthen NTT Com’s EU capabilities to meet increased demand for data center and cloud services, as well as provide increasingly efficient services to migrate customer systems to the cloud. The EU data center market is growing at 9% per year, according to the research firm Gartner, Inc.

NTT Com currently operates data centers in the UK, France, Germany and Spain which e-shelter’s six locations in central Europe will complement perfectly.

NTT Com President and CEO Akira Arima said: “e-shelter is a growing company offering high-quality, highly extensible data center capabilities.

According to e-shelter CEO Rupprecht Rittweger: “As our multinational customers expand beyond EU borders, and undergo rapid ICT evolutions, they are increasingly demanding globally seamless ICT solutions. To meet their demands ahead of our competitors, we believe that the best way to ensure e-shelter’s growth and development is in partnership with NTT Com, which has a commanding presence in Asia and is a leading provider of ICT services worldwide. At the same time, we look forward to strengthening NTT Com’s global ICT infrastructure and market share with our strong presence in Europe.”
