DASAN Zhone Solutions Reports Fourth Quarter and Fiscal Year 2018 Financial Results; Introduces Revenue Guidance for Full Year 2019

Oakland, Calif., February 28, 2019 - DASAN Zhone Solutions, Inc. (NASDAQ: DZSI or the "Company" or “DZSI”), a global leader in fiber access transformation for enterprise and service provider networks, today reported fourth quarter and fiscal year results for the period ended December 31, 2018.  The Company also provided its outlook for the three months ending March 31, 2019 and introduced revenue guidance for the full year ending December 31, 2019.

Fourth Quarter 2018 Financial Performance:

(excludes KEYMILE figures)

• Revenue was $74.7 million, which was in-line with the Company’s guidance and an increase of 8.8% year-over-year.

• GAAP gross margin was 31.0%, which reflected strong revenue contribution from the Company’s Asia Pacific and South Korea geographies, which contributed approximately 69% of the quarter’s revenue.

• GAAP net income attributable to DZSI was $(1.3) million, or $(0.08) per diluted share, which reflected approximately $2.9 million in non-recurring operating expenses resulting from merger and acquisition related expenses for the KEYMILE acquisition as well as an accrual for a special 2018 performance-based bonus, which is expected to be paid in the first quarter of 2019.

• Without the inclusion of these non-recurring operating expenses, the Company would have generated a positive net income.

• GAAP operating expenses were $23.1 million.  Non-GAAP adjusted operating expenses were $20.1 million, which came in $0.9 million better than the low end of the Company’s guidance of between $21 million and $22 million.

• Non-GAAP adjusted EBITDA was $3.0 million, which was in-line with the Company’s adjusted EBITDA guidance of between $3 million to $4 million.  Non-GAAP financial measures are reconciled to the most comparable GAAP measures in the tables set forth at the end of this press release.

• Total cash and cash equivalents (excluding restricted cash) as of December 31, 2018 were $27.7 million, compared to $17.5 million as of December 31, 2017.

Full Year 2018 Financial Performance:

(excludes KEYMILE figures)

• Revenue was $282.3 million, which reflected an increase of 14.3% year-over-year.

• GAAP gross margin was 32.4%.

• GAAP net income attributable to DZSI was $2.0 million, or $0.12 per diluted share, which reflected approximately $3.1 million in non-recurring operating expenses resulting from merger and acquisition related expenses for the KEYMILE acquisition as well as an accrual for a special 2018 performance-based bonus that is expected to be paid in the first quarter of 2019.

• Non-GAAP adjusted EBITDA was $12.0 million, which exceeded the Company’s adjusted EBITDA guidance of $11.5 million.

Management Commentary:

"2018 was a year of strong progress for DZSI,” said Yung Kim, CEO of DZSI. “We are experiencing strong customer feedback for our new generation 10G PON broadband, Whole Home WiFi, and our newly designed generation of plug-and-play FiberLAN solutions.  On the customer side, we continue to demonstrate 5G mobile backhaul leadership, working alongside LG U+ in the roll-out of the first commercial 5G wireless network in South Korea.  I am also excited by a recent win with the South Korea Ministry of Education to provide SDN based wired and wireless infrastructure to connect more than 11,000 elementary, middle, and high schools, across the country.  On the leadership front, we deepened our management bench, formalizing our Chief Operating Officer role, adding a new Head of Asia Pacific, and welcoming Lothar Schwemm and the rest of the KEYMILE leadership team to DZS.”

Michael Golomb, CFO of DZSI, said:” We delivered strong results in the fourth quarter, with revenue growing 9% year-over-year, and driving $3.0 million of adjusted EBITDA.  For the full year, we delivered 14% revenue growth and $12 million in adjusted EBITDA, demonstrating our ability to grow profitability. We also made great strides in improving our capital structure with regards to our debt.  In fact, we recently closed on a new three-year, $40 million senior secured credit facility, inclusive of a $25 million term loan, with the proceeds used to strengthen our cash position to support continued growth in our business.”

Business Outlook:

DZSI’s business outlook is based on current expectations.  The following statements are forward-looking, and actual results can differ materially based on market conditions and factors set forth under “Forward-Looking Statements” below.  The Company will provide the pro forma combined financials for 2018, inclusive of KEYMILE, in the 8-K filing expected in mid-March.

• First Quarter 2019 Guidance:

- Organic revenue target of $63 million to $66 million, which represents 6% to 11% organic growth from Q1 2018, and revenue target of $70 million to $74 million including KEYMILE.

- GAAP gross margin target of between 31% and 33% (inclusive of KEYMILE), non-GAAP adjusted operating expenses target of $26 million to $29 million (inclusive of KEYMILE), and non-GAAP adjusted EBITDA to be approximately $(4) million, which is primarily driven by seasonality impacts, particularly in the KEYMILE business.

• Full Year 2019 Revenue Guidance:  Revenue target of $345 million to $360 million.

Non-GAAP Financial Measures

To supplement DZSI's consolidated financial statements presented in accordance with GAAP, DZSI uses adjusted EBITDA, a non-GAAP measure DZSI believes is appropriate to enhance an overall understanding of DZSI's past financial performance and prospects for the future. These adjustments to GAAP results are made with the intent of providing greater transparency to supplemental information used by management in its financial and operational decision-making. These non-GAAP results are among the primary indicators that management uses as a basis for making operating decisions because they provide meaningful supplemental information regarding the Company's operational performance, including the Company's ability to provide cash flows to invest in research and development, and to fund capital expenditures. In addition, these non-GAAP financial measures facilitate management's internal comparisons to the Company's historical operating results and comparisons to competitors' operating results. The presentation of this additional information is not meant to be considered in isolation or as a substitute for measures of financial performance prepared in accordance with GAAP. A reconciliation between net income (loss) and adjusted EBITDA is provided in a table immediately following the Unaudited Condensed Consolidated Statements of Comprehensive Income (Loss) below.
