NEW YORK, NY (May 5, 2014) - Varonis Systems, Inc. (Nasdaq: VRNS), the leading provider of software solutions for unstructured, human-generated enterprise data, today announced results for the first quarter ended March 31, 2014.

Yaki Faitelson, Varonis CEO, said, “I am very pleased with the Company’s strong first quarter financial performance. We continue to achieve meaningful growth across both new and existing customers, driven by the investments we have made to expand our sales teams as well as broaden our product offerings to address an ever-growing set of use cases. Organizations of all sizes are seeing rapid growth in the volume of human-generated data, which are typically the most valuable and sensitive files a company has. The growth of this data carries big opportunities as well as serious threats, and our solutions enable companies to realize value from their human-generated data, manage it efficiently and protect it effectively.”

Financial Highlights for the First Quarter Ended March 31, 2014

Revenues:

Operating Loss

Net Loss

In our non-GAAP Q1 2014 earnings per share, the Company calculated shares of common stock outstanding after accounting for the automatic conversion of Varonis’ then outstanding shares of convertible preferred stock into 15.1 million shares of common stock and the issuance of 5.3 million shares of common stock in our initial public offering as though such events had occurred at the beginning of the period. In the same calculation for Q1 2013, the Company accounted for the automatic conversion of Varonis’ then outstanding shares of convertible preferred stock into 14.9 million shares of common stock at the beginning of the period.

The tables at the end of this press release include a reconciliation of GAAP to non-GAAP loss from operations and net loss for the three months ended March 31, 2014 and 2013. An explanation of these measures is also included below under the heading “Non-GAAP Financial Measures.”

Financial Outlook

For the second quarter of 2014, Varonis expects revenues in the range of $22.9 million to $23.4 million. The Company anticipates second quarter 2014 non-GAAP operating loss in the range of $(4.1) million to ($3.8) million and non-GAAP loss per basic share in the range of ($0.18) to ($0.16), based on a tax provision of $0.2 million to $0.3 million and 24.5 million basic shares outstanding. Expectations of non-GAAP loss from operations and non-GAAP loss per basic share exclude stock-based compensation expense.

Non-GAAP Financial Measures

Varonis believes that the use of non-GAAP operating loss and non-GAAP net loss is helpful to our investors. These measures, which the Company refers to as our non-GAAP financial measures, are not prepared in accordance with GAAP.

For the three months ended March 31, 2014 and 2013, non-GAAP operating loss is calculated as operating loss excluding stock-based compensation expense.

For the three months ended March 31, 2014 and 2013, non-GAAP net loss is calculated as net loss excluding (i) stock-based compensation expense and (ii) financial expenses resulting from the revaluation of warrants to purchase convertible preferred stock.

Because of varying available valuation methodologies, subjective assumptions and the variety of equity instruments that can impact a company’s non-cash expense, the Company believes that providing non-GAAP financial measures that exclude stock-based compensation expense allow for more meaningful comparisons between our operating results from period to period. In addition, the Company believes that excluding financial expenses with respect to revaluation of warrants to purchase convertible preferred stock allows for more meaningful comparison between our net loss from period to period, especially since upon the closing of the IPO, the warrants automatically converted into warrants to purchase our common stock, and as a result, are no longer evaluated at each balance sheet date.

Each of our non-GAAP financial measures is an important tool for financial and operational decision making and for evaluating our own operating results over different periods of time. The non-GAAP financial data are not measures of our financial performance under U.S. GAAP and should not be considered as alternatives to operating loss or net loss or any other performance measures derived in accordance with GAAP. Non-GAAP financial measures may not provide information that is directly comparable to that provided by other companies in our industry, as other companies in our industry may calculate non-GAAP financial results differently, particularly related to non-recurring, unusual items. In addition, there are limitations in using non-GAAP financial measures because the non-GAAP financial measures are not prepared in accordance with GAAP, may be different from non-GAAP financial measures used by other companies and exclude expenses that may have a material impact on our reported financial results. Further, stock-based compensation expense has been, and will continue to be for the foreseeable future, a significant recurring expense in our business and an important part of the compensation provided to our employees. The presentation of non-GAAP financial information is not meant to be considered in isolation or as a substitute for the directly comparable financial measures prepared in accordance with GAAP. Varonis urges investors to review the reconciliation of our non-GAAP financial measures to the comparable GAAP financial measures included below, and not to rely on any single financial measures to evaluate our business.
