Cyren Reports Fourth Quarter and Full Year 2018 Financial Results

- - -

Full year 2018 revenue grew 17% while fourth quarter revenue was up 26% year-over-year

McLean, Va. – February 13, 2019 – Cyren (NASDAQ: CYRN) today announced its fourth quarter and full year 2018 financial results for the period ending December 31, 2018.

During the fourth quarter, Cyren reported quarterly revenues of $9.5 million – an increase of 26% over the fourth quarter of 2017. For the full year ending 2018, Cyren reported revenues of $35.9 million, up 17% over the full year 2017, and representing the highest annual revenue total the company has ever recorded.

“We are pleased with our fourth quarter performance that tops off a record breaking year for Cyren,” said Lior Samuelson, Chairman and CEO of Cyren. “During the quarter, we brought a number of new enterprise customers onto the Cyren Cloud Security platform, and renewed contracts with two of our largest customers using our Threat Intelligence Services. Throughout 2018, we had a number of significant achievements including signing our largest CCS enterprise customer, with over 100,000 active email accounts, and the largest contract in our company’s history. We plan on launching some exciting new enterprise products over the coming two quarters, and are looking forward to continued progress in 2019.”

Cyren previously discussed that it plans to launch two significant products during 2019. The company is developing a next generation enterprise class anti-phishing solution which is intended to allow enterprises to proactively remediate and remove phishing emails after they have been delivered to a user’s mailbox, regardless of who the company is using as an email gateway for their primary level of protection. Cyren also announced a collaboration with Microsoft to integrate Cyren web security technology directly into the Windows Defender Advanced Threat Protection platform in order to provide an additional layer of protection to Windows Defender enterprise customers. Both products are anticipated to be generally available later in 2019.

For information regarding the non-GAAP financial measures discussed in this release, please see “Use of Non-GAAP Financial Measures” and “Reconciliation of Selected GAAP Measures to Non-GAAP Measures.”

Recent Business Highlights:

● During the fourth quarter, Cyren expanded service to its largest enterprise customer – an international company who selected Cyren’s CCS platform for email security and cloud sandboxing. The multi-year, multi-million dollar contract which was previously announced with 80,000 enterprise users, has grown to over 100,000 active enterprise users on the Cyren network.

● Also in the fourth quarter, Cyren renewed and expanded two of the company’s top 5 revenue customers using Cyren’s Threat Intelligence Services. One of the contracts was renewed at a 17% premium, and includes a significant multi-year prepayment, which will have a positive impact on operating cash flow during the first quarter of 2019.

● Cyren recently announced a partnership with Microsoft to integrate its web security technology directly into Windows Defender Advanced Threat Protection (ATP). The new integrated offering will initially be made available as a private preview with a select set of enterprise customers expected during the first half of 2019, with the goal of reaching general availability for all Windows Defender ATP customers later in the year.

● In January, Cyren announced that it will be voluntarily delisting from the Tel Aviv Stock Exchange (TASE). Cyren will continue to maintain its headquarters in Herzliya, Israel and operate as an Israeli-registered company, but the move is an effort to simplify regulatory filings and concentrate fragmented trading volume onto the Nasdaq exchange. The delisting is expected to become effective in April.

Use of Non-GAAP Financial Measures:

Non-GAAP financial measures consist of GAAP financial measures adjusted to exclude: stock-based compensation expenses, amortization of acquired intangible assets and deferred taxes related to acquisitions, one-time gain from sale of investment in affiliate, adjustments to earn-out obligations, capitalization of technology, accretion of discount on convertible note and change in fair value of the embedded conversion feature. The purpose of such adjustments is to give an indication of the company's performance exclusive of non-cash charges and other items that are considered by management to be outside of the company's core operating results. The company's non-GAAP financial measures are not meant to be considered in isolation or as a substitute for comparable GAAP measures, and should be read only in conjunction with the company's consolidated financial statements prepared in accordance with GAAP.

Company management regularly uses supplemental non-GAAP financial measures internally to understand, manage and evaluate the business and make operating decisions.

These non-GAAP measures are among the primary factors management uses in planning for and forecasting future periods. The company believes this adjustment is useful to investors as a measure of the ongoing performance of the business. The company believes these non-GAAP financial measures provide consistent and comparable measures to help investors understand the company's current and future operating cash flow performance. These non-GAAP financial measures may differ materially from the non-GAAP financial measures used by other companies. Reconciliation between results on a GAAP and non-GAAP basis is provided in a table immediately following the Consolidated Statements of Income. The presentation of this non-GAAP financial information is not intended to be considered in isolation or as a substitute for the financial information prepared and presented in accordance with GAAP. Management uses both GAAP and non-GAAP measures when evaluating the business internally and therefore felt it important to make these non-GAAP adjustments available to investors.

This press release contains forward-looking statements, including projections about the company's business, within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. For example, statements in the future tense, and statements including words such as "expect," "plan," "estimate," "anticipate," or "believe" are forward-looking statements. These statements are based on information available at the time of the press release and the company assumes no obligation to update any of them. The statements in this press release are not guarantees of future performance and actual results could differ materially from current expectations as a result of numerous factors, including business conditions and growth or deterioration in the internet security market, technological developments, products offered by competitors, availability of qualified staff, and technological difficulties and resource constraints encountered in developing new products, as well as those risks described in the company's Annual Reports and current reports on Form 8-K, which are available through www.sec.gov.
