Forward-Looking Statements

This press release contains “forward-looking statements,” including statements regarding our ability to meet our financial goals for the year, the anticipated benefits of our acquisition of Appcito, including expanding our addressable market. Forward-looking statements are subject to known and unknown risks and uncertainties and are based on assumptions that may prove to be incorrect, which could cause actual results to differ materially from those expected or implied by the forward-looking statements. Factors that may cause actual results to differ include the continued market adoption of our products, our ability to successfully anticipate market needs and opportunities, our timely development of new products and features, any loss or delay of expected purchases by our largest end-customers, our ability to attract and retain new end-customers, continued growth in markets relating to network security, our ability to hire, retain and motivate qualified personnel, the ability of our sales team to execute well, our ability to shorten our close cycles, the ability of our channel partners to sell our products, our ability to achieve or maintain profitability while continuing to invest in our sales, marketing and research and development teams, variations in product mix or geographic locations of our sales, fluctuations in currency exchange rates, risks associated with our significant presence in international markets, the cost and potential outcomes of existing and future litigation, increased cost requirements of being a public company and future sales of substantial amounts of our common stock in the public markets, or the perception that such sales might occur, and litigation risks and costs.

More information about potential factors that could affect the company's business and financial results is included in our annual and quarterly reports on file with the SEC. These filings are available on the SEC's website at https://www.sec.gov/and the company’s website.

All forward-looking statements in this press release are based on information available to the company as of the date hereof. We disclaim any obligation to update information contained in these forward-looking statements whether as a result of new information, future events, or otherwise.

Non-GAAP Financial Measures

In addition to disclosing financial measures prepared in accordance with U.S. generally accepted accounting principles (GAAP), this press release and the accompanying tables contain certain non-GAAP financial measures, including non-GAAP net income (loss). Non-GAAP financial measures do not have any standardized meaning and are therefore unlikely to be comparable to similarly titled measures presented by other companies.

A10 Networks considers these non-GAAP financial measures to be important because they provide useful measures of the operating performance of the company, exclusive of unusual events or factors that do not directly affect what we consider to be our core operating performance, and are used by the company's management for that purpose. We define non-GAAP net income (loss) as our net income (loss) excluding: (i) stock-based compensation and (ii) amounts paid in settlement of litigation, and other legal expenses associated with these settlements.

We have included non-GAAP net income (loss) in this press release. Non-GAAP financial measures are presented for supplemental informational purposes only for understanding the company's operating results. The non-GAAP financial measures should not be considered a substitute for financial information presented in accordance with GAAP, and may be different from non-GAAP financial measures presented by other companies. Please see the reconciliation of non-GAAP financial measures to the most directly comparable GAAP measure attached to this release.
