“Strong demand for our proprietary security-led solutions drove record revenues for the quarter and the full-year, with continued broad-based growth across both enterprises and service providers and in each key geographic region, on a constant-currency basis,” said Dhrupad Trivedi, President and Chief Executive Officer of A10 Networks. “Increasingly, A10 is positioned as a diversified, differentiated security solutions provider, structured to mitigate fluctuations from any single customer or region. While
we are not immune from recessionary impacts, our industry leadership makes our offerings a priority over discretionary investments. We remain well-positioned for continued success with both enterprise and service provider customers.”
“In 2022 we successfully navigated supply chain constraints, maintained robust gross margins and effectively managed our operating expenses, which drove profitability and free cash flow,” added Trivedi. “With revenue growth that outpaced operating expenses, we were able to grow our bottom line faster than our top line. For the year, we delivered record non-GAAP operating income and EBITDA margins, enabling us to repurchase more than $79.3 million of our stock and return further capital to shareholders through meaningful cash dividends. Simultaneously, we continued to strategically invest in technology, augmenting our already durable differentiators and making our business increasingly resilient. We remain committed to delivering revenue growth that outpaces our peer set, navigating recessionary headwinds better than our peers and delivering solid bottom-line growth, with expected double-digit growth in 2023 full-year non-GAAP EPS. We continue to carry no debt and hold $151.0 million of cash and cash equivalents.”

Forward-Looking Statements
This press release contains “forward-looking statements,” including statements regarding our anticipated future financial results, quarterly dividend payments, drivers of growth, strategy, demand, supply chain challenges, positioning, growth and Adjusted EBITDA and non-GAAP EPS expectations. 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 impact of the COVID-19 pandemic on our business and the business of our customers; a significant decline in global macroeconomic or political conditions that have an adverse impact on our business and financial results; business interruptions related to our supply chain; our ability to manage our business and expenses if customers cancel or delay orders; 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; our ability to timely file periodic reports required to be filed under the Securities Exchange Act of 1934; and other risks that are described in “Risk Factors” in our periodic filings with the Securities and Exchange Commission, including our Form 10-K filed with the Securities and Exchange Commission on March 8, 2022. We do not intend to update or alter our forward-looking statements, whether as a result of new information, future events or otherwise, except as required by applicable law.
Non-GAAP Financial Measures
In addition to disclosing financial measures prepared in accordance with U.S. generally accepted accounting principles (GAAP), we refer to certain non-GAAP financial measures, including non-GAAP net income, non-GAAP net income per basic and diluted share (or non-GAAP EPS), non-GAAP gross profit and gross margin, non-GAAP operating income 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.
We define non-GAAP net income as our GAAP net income excluding: (i) stock-based compensation and related payroll tax, (ii) impairment of investment, (iii) amortization expense related to acquisition, (iv) global distribution center transition expense, (v) litigation and investigation expense (recovery, (vi) non-recurring facilities expense, (vii) restructuring expense and related taxes, (viii) tax benefit of amended returns and (ix) release of deferred tax asset valuation allowance. We define non-GAAP net income per basic and diluted share as our non-GAAP net income divided by our basic and diluted weighted-average shares outstanding. We define tax effected non-GAAP net income as non-GAAP net income adjusted for the income tax effect of excluding the non-GAAP items (i) to (ix) listed above. We define non-GAAP gross profit as our GAAP gross profit excluding (i) stock-based compensation and related payroll tax, and (ii) global distribution center transition expense. We define non-GAAP gross margin as our non-GAAP gross profit divided by our GAAP revenue. We define non-GAAP operating income as our GAAP income from operations excluding (i) stock-based compensation and related payroll tax, (ii) amortization expense related to acquisition and (iii) global distribution center transition expense. We define non-GAAP operating margin as our non-GAAP operating income divided by our GAAP revenue. We define non-GAAP operating expenses as our GAAP operating expenses excluding (i) stock-based compensation and related payroll tax, (ii) amortization expense related to acquisition and (iii) global distribution center transition expense. We define Adjusted EBITDA as our GAAP net income excluding (i) interest and other (income) expense, net, (ii) depreciation and amortization expense, (iii) provision for (benefit from) income taxes, (iv) stock-based compensation and related payroll tax, (v) litigation and investigation expense (recovery), (vi) non-recurring facilities expense, (vi) impairment of investment, (vii) global distribution center transition expense and (ix) restructuring expense.
Non-GAAP financial measures are presented for supplemental informational purposes only for understanding the company's operating results.

Q4 2022 Financial Results & Commentary February 7, 2023

Cautionary Statements & Disclosures This presentation and the accompanying oral presentation contain “forward-looking” statements that are based on our management’sbeliefs and assumptions, including statements regarding our future financial performance, strategy, routes to market, technical differentiation, positioning, capital allocation strategy, expansion opportunities, growth, profitability, market growth, as well as market and technology trends. Forward-looking statements are subject to known and unknown risks, uncertainties, assumptions and other factors that could cause our actual results to differ materially from those anticipated or implied by our forward-looking statements. These factors include, but are not limited to, the impact of the COVID-19 pandemic on our business, on the business of our customers and suppliers, and on the global economy in general, a significant decline in global macroeconomic or political conditions, execution risks related to closing key deals and improving our execution, successfully executing our strategies, market adoption of our products, successfully anticipating market needs and opportunities, timely development of new products and features, achieving or maintaining profitability, loss or delay of expected purchases, our ability to maintain or improve our competitive position; competitive and execution risks related to cloud-based computing trends, attracting and retaining new end-customers, maintaining and enhancing our brand and reputation, changes demanded by our customers in the deployment and payment model for our products, growth in markets relating to network security, the success of any future acquisitions or investments, the success of our partnerships with technology providers, the ability of our sales team to execute well, our ability to shorten our close cycle, the ability of our channel partners to sell our products, variations in product mix or geographic locations of our sales, our presence in international markets, andother factors described in our quarterly reports on Form 10-Q, annual reports on Form 10-K and other filings made with the Securities and Exchange Commission, to which your attention is directed. The forward-looking statements included in this presentation are based on current expectations and beliefs as of February 7, 2023, only. We do not intend to update this information contained in the forward-looking statements, except as required by law. This presentation and the accompanying oral presentation also include certain non-GAAP financial measures including Non-GAAP gross margin, non-GAAP operating income, non-GAAP net income, non-GAAP operating margin, Adjusted EBITDA and Non-GAAP EPS. Non-GAAP financial measures do not have any standardized meaning and are therefore unlikely to be comparable to similarly titles 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. 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, (iii) global distribution center transition 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 (i) stock-based compensation and related payroll tax, and (ii) global distribution center transition expense. 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 payroll tax, (ii) amortization expense related to acquisition, and (iii) global distribution center transition 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 payroll tax, (ii) amortization expense related to acquisition, and (iii) global distribution center transition expense. We define Adjusted EBITDA as our GAAP net income (loss) excluding (i) interest expense (if any), (ii) interest income and other (income) expense, net, (iii) depreciation and amortization expense, (iv) provision (benefit) for income taxes, (v) stock-based compensation and related payroll tax, and global distribution center transition expense. A reconciliation between GAAP and non-GAAP financial measures can be found in the appendix to this document and in the accompany financial results press release.
