Strategic Acquisition Further Expands Global Footprint to Serve More Customers Globally and Accelerates the Company’s Vision of Empowering Global Advancement

Oakland, Calif. – October 8, 2018 – DASAN Zhone Solutions, Inc. (NASDAQ: DZSI or the “Company”), a global leader in fiber access transformation for enterprise and service provider networks, announced its intent to acquire KEYMILE, a leading solution provider and manufacturer of telecommunication systems for broadband access. The acquisition will bring together two major broadband vendors to empower global service providers with freedom of choice and to advance the internet connection experience to their customers.

Founded in 2002 and headquartered in Hanover, Germany, KEYMILE offers a series of multi-service access platforms for FTTx network architectures, including ultra-fast broadband copper access based on VDSL/Vectoring & G. Fast technology. With this acquisition, DZS will further expand its footprint in the global broadband access market and gain exposure to hundreds of customers. KEYMILE has strong regional presence in Europe, Latin America and other regions which complement DZS.

The transaction is expected to close in the fourth quarter of 2018, subject to customary closing conditions and required regulatory approvals. Following the close of the acquisition, KEYMILE CEO, Mr. Lothar Schwemm, will continue to serve as General Manager of KEYMILE.

“I am delighted to welcome KEYMILE to our DZS family. This acquisition represents the continuation of our transformation from a leading networking equipment provider to a solutions vendor with next-generation software and services,” said Yung Kim, CEO, DZS. “As a combined DZS, we can capture the broader, global market opportunity and continue to elevate our position as a leading broadband vendor and trusted advisor to prominent carriers and enterprises.  I believe the combination of our two companies is going to prove to be very powerful in the market.”

“Much like the transformational merger of DASAN and Zhone two years ago, this acquisition represents an attractive opportunity to grow in markets where we’ve historically had a smaller footprint and to build on the momentum in our business,” said Michael Golomb, CFO, DZS. “We will execute to the same prudent playbook around sustainable, profitable growth and continue to be good stewards of capital with the KEYMILE acquisition.”

“We are excited to join DZS, combine our solutions and people with the unified goal of helping our service provider and enterprise customers, through offering them greater choice among industry-leading products and solutions as our customers migrate to a connected broadband world,” said Lothar Schwemm, CEO, KEYMILE. “Further, with the expanded global footprint, we can leverage global manufacturing capabilities and expanded logistics, driving more customer value.”

Additional information relating to the acquisition can be found in the accompanying 8-K filing the Company filed today with the Securities and Exchange Commission.
