Digi International Acquires Sarian Systems

Digi International® Inc. (NASDAQ: DGII) announced the acquisition of Sarian Systems, Limited. a privately held U.K. based corporation and a leader in the European wireless router market. The acquisition is a cash transaction for approximately $30.5 million for all the outstanding ordinary shares of Sarian. The purchase price of $30.5 million takes into account cash on Sarian’s balance sheet as of the acquisition date, estimated to be $2.5 million.

Sarian Systems designs, develops and manufactures advanced wireless/cellular IP Routing equipment for mission critical applications. Having developed its own comprehensive IP operating system and software, Sarian delivers customers technical excellence, flexibility and rapid customization. With a vertical market focus and deep protocol knowledge, Sarian has developed a strong customer base in ATM connectivity; retail and payment systems connectivity; remote monitoring or telemetry; lottery terminal connectivity; and wireless backup of wired broadband connections. This vertical focus is highly complementary to Digi’s market approach.

“As we got to know the Sarian team and business, it quickly became apparent that this acquisition was a great fit on many levels,” said Joe Dunsmore, Chairman, President and CEO of Digi. “We’re acquiring a high-growth, profitable wireless business that can be expanded from Europe into other parts of the world. We have very similar corporate cultures and vertical go-to-market strategies, so integration will be straightforward. And with Sarian’s strong European engineering and sales presence, we’re immediately increasing the international content and capabilities of our business.”

“With the great cultural and technical fit we see Digi as the ideal partner to take the fast growing business that we have in Europe, Scandinavia and Southern Africa into many other geographic regions,” said Andrew Hood, Managing and Technical Director of Sarian. “Digi’s market-leading Drop-in Networking technology and our flexible wired and wireless IP routing capability create a powerful global combination.”
