• Quarterly Revenue of $136.1 million, similar to prior year
• First Quarter Diluted EPS of $0.05; Adjusted Diluted EPS of $0.10
• Reduces Full Year 2018 Revenue and Adjusted EBITDA guidance
• Revitalized leadership team focused on improved execution and strategy

Yair Averbuch, Interim Chief Executive Officer, commented, "Our first quarter results fell short of our expectations. We are working with urgency and purpose to improve execution and resume growth. We plan to enhance our execution, particularly in the U.S. market, with a focus on growth and margins. We believe that we have significant opportunities to leverage our global operating platform, powerful global brand, innovative and leading products and our considerable financial strength to return to compelling levels of value creation for our shareholders."

Gross margin in the first quarter was 25.2% compared to 36.1% in the same period in the prior year. The decrease in margin primarily reflects: increased product complexity and related manufacturing challenges in Israel; inventory and logistical inefficiencies primarily related to the U.S. distribution operation, the majority of which the company does not expect will continue in the remainder of the year; and higher raw material prices.

Adjusted EBITDA, which excludes expenses for share-based compensation as well as legal settlements and loss contingencies, was $11.2 million in the first quarter of 2018, a margin of 8.2%. This compares to adjusted EBITDA of $24.3 million in the prior year's first quarter, a margin of 17.8%. This year-over-year margin comparison primarily reflects the decline in gross margin, as described above.

The Company reported net income attributable to controlling interest for the first quarter of 2018 of $1.5 million compared to income of $11.1 million in the same quarter in the prior year. Diluted net income per share for the first quarter was $0.05 compared to $0.31 in the prior year's first quarter, both on 34.4 million shares. Adjusted diluted net income per share for the first quarter was $0.10 compared to the prior year's first quarter level of $0.36.

The Company's balance sheet as of March 31, 2018 remained strong, including cash, cash equivalents and short-term bank deposits of $112.1 million as compared to a total of $138.7 million on December 31, 2017 and to $121.0 million on March 31, 2017. The Company noted that during the quarter, it used approximately $14.2 million in cash, as previously announced, to conclude long-standing arbitration as well as $10.5 million in cash for the payment of a previously authorized dividend paid during the first quarter.

The non-GAAP measures presented by the Company should be considered in addition to, and not as a substitute for, comparable GAAP measures. A reconciliation of GAAP net income attributable to controlling interest to adjusted net income attributable to controlling interest and net income to Adjusted EBITDA are provided in the schedules within this release. The Company provides these non-GAAP financial measures because it believes that they present a better measure of the Company's core business and management uses the non-GAAP measures internally to evaluate the Company's ongoing performance. Accordingly, the Company believes that they are useful to investors in enhancing an understanding of the Company's operating performance.
