Forward-Looking Statements

This press release contains “forward-looking statements,” including statements regarding our position to help our customers; projections for our future operating results; and the strength and capabilities of our talent base. 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 execution risks related to closing key deals and improving our execution, the continued market adoption of our products, our ability to successfully anticipate market needs and opportunities, our timely development of new products and features, our ability to achieve or maintain profitability, any loss or delay of expected purchases by our largest end-customers, our ability to maintain or improve our competitive position, competitive and execution risks related to cloud-based computing trends, our ability to attract and retain new end-customers and our largest end-consumers, our ability to maintain and enhance our brand and reputation, changes demanded by our customers in the deployment and payment model for our products, continued growth in markets relating to network security, the success of any future acquisitions or investments in complementary companies, products, services or technologies, 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, variations in product mix or geographic locations of our sales, risks associated with our presence in international markets, weaknesses or deficiencies in our internal control over financial reporting, and our ability to timely file periodic reports required to be filed under the Securities Exchange Act of 1934.

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 table contain certain non-GAAP financial measures, including non-GAAP net income (loss), non-GAAP net income (loss) per basic and diluted share, non-GAAP gross profit and gross margin, non-GAAP operating income (loss) and operating margin, non-GAAP operating expenses, and Adjusted EBITDA. 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.

Non-GAAP financial measures should not be considered in isolation from, or as a substitute for, financial information prepared in accordance with GAAP. Investors are encouraged to review the reconciliation of these non-GAAP financial measures to their most directly comparable GAAP financial measures provided in the financial statement tables below. A reconciliation of non-GAAP guidance measures to corresponding GAAP measures on a forward-looking basis is not available due to high variability and low visibility with respect to the charges which are excluded from these non-GAAP measures.

We define non-GAAP net income as our GAAP net income (loss) excluding: (i) stock-based compensation and related payroll tax, (ii) amortization expense related to acquisition and (iii) non-recurring expenses associated with the litigation settlement expense and internal investigation, (iv) restructuring expense, and related tax, and (v) non-recurring facilities expense. We define non-GAAP net income per basic and diluted share as our non-GAAP net income (loss) divided by our basic and diluted weighted-average shares outstanding. We define non-GAAP gross profit as our GAAP gross profit excluding stock-based compensation and related payroll tax. We define non-GAAP gross margin as our non-GAAP gross profit divided by our GAAP revenue. We define non-GAAP operating income (loss) as our GAAP income (loss) from operations excluding (i) stock-based compensation, and related tax, (ii) amortization expense related to acquisition and (iii) non-recurring expenses associated with the litigation settlement expense and internal investigation, (iv) restructuring expense, and related tax, and (v) non-recurring facilities expense. We define non-GAAP operating margin as our non-GAAP operating income (loss) divided by our GAAP revenue. We define non-GAAP operating expenses as our GAAP operating expenses excluding (i) stock-based compensation, and related tax, (ii) amortization expense related to acquisition, (iii) non-recurring expenses associated with the litigation settlement expense and internal investigation, (iv) restructuring expense, and related tax, and (v) non-recurring facilities expense. We define Adjusted EBITDA as our GAAP net income (loss) excluding (i) interest expense, (ii) interest income and other (income) expense, net, (iii) depreciation and amortization expense, (iv) provision for income taxes, (v) stock-based compensation and related payroll tax, (vi) litigation settlement and internal investigation expense (vii) restructuring expense, and related tax, and (viii) non-recurring facilities expense.

We have included our non-GAAP net income (loss), non-GAAP gross profit and gross margin, non-GAAP operating income (loss) and operating margin, non-GAAP operating expenses and Adjusted EBITDA in this press release. Non-GAAP financial measures are presented for supplemental informational purposes only for understanding the company’s operating results.
