Burlington, MA – July 25, 2018 – Attunity Ltd. (NasdaqCM: ATTU), a leading provider of data integration and Big Data management software solutions, today reported its unaudited financial results for the three-month period ended June 30, 2018.

“We are pleased to report record results for the second quarter of 2018. We continued to accelerate our business, and achieved license revenue growth of 86% year-over-year and total revenue growth of 47% year-over-year for the quarter. The momentum has been building over the past several quarters, driven by the shift in the analytics market to the next level of data lake adoption, the fast growth of the Cloud as an enterprise data platform, and our strong execution. With the combination of our innovative solutions and strategic partnerships with key industry leaders, we are strongly positioned to capitalize on this growing market opportunity,” stated Shimon Alon, Chairman and CEO of Attunity.

“The introduction of our recurring revenue pricing model has quickly resulted in strong customer adoption, with the majority of Replicate direct license deals in the quarter being term-based. We anticipate this trend to continue in the second half of 2018 and beyond. As a result of our strong first half of 2018 and the momentum we see for the full year, we determined to raise our guidance,” concluded Mr. Alon.

Recent Operational Highlights

Approximately 60% of the number of Replicate direct license deals in the second quarter were term-based, which represents approximately 70% of Replicate direct license revenue

Closed two large term-based deals, one for a total of $2.8 million and one for a total of $2.3 million

Closed first large GDPR solution sale for a total of $0.9 million

Introduced new Gold Client solution to enable GDPR compliance for SAP® environments

Conducted a strategic customer advisory board with representatives from 20 large companies

Hired a new EVP of North America Sales Operations, who previously served as a sales executive of Oracle’s data integration business, including GoldenGate

Updated Outlook for Full Year 2018

The Company increased its outlook for the full year 2018 as follows:

Total revenue is estimated to grow to between $78 and $81 million, compared with prior (updated) guidance of $75 to $78 million.

Non-GAAP operating margin is estimated to be between 7% and 10%, compared with prior (updated) guidance of 6% to 10%.

Financial Reconciliation to non-GAAP figures for the updated 2018 outlook:

	From			To
GAAP Operating Profit (Loss) Margin		0	%		4	%
Equity-based compensation		(6	)%		(5	)%
Amortization associated with acquisitions		(1	)%		(1	)%
Non-GAAP Operating Profit Margin (1)		7	%		10	%

(1) Non-GAAP Operating Profit Margin is calculated by dividing the non-GAAP Operating Profit by the total non-GAAP revenues for the period.

These estimates for 2018 reflect the Company's current and preliminary views, which are subject to change (see below under "Safe Harbor Statement") and are based on various assumptions, including the continued expanded adoption of the Cloud as a leading data platform, the continued adoption of modern analytics and the improved execution capabilities of our expanded sales team.

The Company clarified that it does not expect to provide or update guidance more often than on an annual basis.

(*) New Revenue Accounting Standard

Effective January 1, 2018, Attunity adopted the FASB-issued ASU, No. 2014-09, "Revenue from Contracts with Customers (Topic 606)", or ASC 606, a new accounting standard related to revenue recognition. Attunity adopted ASC 606 using the modified retrospective method, which means that the comparative financial information for the three and six month periods ended June 30, 2017 has not been restated in the current financial statements under the new accounting standard. Accordingly, the percentage changes from the 2017 to 2018 periods differ from what they would have been had the same accounting standards been in effect for both periods. In the interest of comparability during the transition year to ASC 606, the company has provided revenue, operating expenses, operating income (loss), financial income, taxes on income, net income (loss) and earnings per share information in accordance with both ASC 606 and revenue recognition rules in effect prior to the adoption of ASC 606 (ASC No. 985-605, or ASC 605). For further details, see the Impact of the Adoption of ASC 606 table later in this press release and the note thereto.

(**) Use of Non-GAAP Financial Information
In addition to reporting financial results in accordance with U.S. generally accepted accounting principles, or GAAP, Attunity uses Non-GAAP measures of net income (loss), operating expenses, operating profit (loss), and diluted net income (loss) per share, which are adjusted from results based on GAAP to exclude amortization associated with acquisitions, equity-based compensation expenses, non-cash financial expenses, such as the effect of a revaluation of liabilities presented at fair value, and the effect of changes in deferred taxes related to non-GAAP adjustments. Attunity’s management believes the non-GAAP financial information provided in this release is useful to investors' understanding and assessment of Attunity's on-going core operations and prospects for the future. Management uses both GAAP and non-GAAP information in evaluating and operating its business internally and as such has determined that it is important to provide this information to investors. The presentation of this non-GAAP financial information is not intended to be considered in isolation or as a substitute for results prepared in accordance with GAAP. For further details, see the Reconciliation of Supplemental Non-GAAP Financial Information table later in this press release.

Statements preceded by, followed by, or that otherwise include the words "believes", "expects", "anticipates", "intends", "estimates", "plans", and similar expressions or future or conditional verbs such as "will", "should", "would", "may" and "could" are generally forward-looking in nature and not historical facts. For example, when we discuss our ability to capitalize on the growing market opportunity, the continued trend of demand for our recurring revenue pricing model and our updated outlook for 2018, we are using forward-looking statements. In addition, announced results for the second quarter of 2018 are preliminary, unaudited and subject to year-end audit adjustment. Because such statements deal with future events, they are subject to various risks and uncertainties and actual results, expressed or implied by such forward-looking statements, could differ materially from Attunity's current expectations. Factors that could cause or contribute to such differences include, but are not limited to, risks and uncertainties relating to: our history of operating losses and ability to achieve or sustain profitability; our business and operating results dependency on the successful and timely implementation of our third party partner solutions; the lengthy sales cycle of our products; competition; acquisitions, including costs and difficulties related to integration of acquired businesses and impairment charges; global economic conditions; the potential loss of one or more of our significant customers or a decline in demand from one or more of these customers; timely availability and customer acceptance of Attunity's new and existing products; risks relating to proprietary rights and risks of infringement; loss of the services of our key personnel; international operations; and other factors and risks on which Attunity may have little or no control. This list is intended to identify only certain of the principal factors that could cause actual results to differ. For a more detailed description of the risks and uncertainties affecting Attunity, reference is made to Attunity's latest Annual Report on Form 20-F which is on file with the Securities and Exchange Commission (SEC) and the other risk factors discussed from time to time by Attunity in reports filed with, or furnished to, the SEC. Except as otherwise required by law, Attunity undertakes no obligation to publicly release any revisions to these forward-looking statements to reflect events or circumstances after the date hereof or to reflect the occurrence of unanticipated events.
