A10 Networks Reports Financial Results for the Second Quarter of 2024

Company Maintains Solid Profitability

SAN JOSE, Calif., July 30, 2024 -- A10 Networks, Inc. (NYSE: ATEN), a leading provider of cybersecurity and infrastructure solutions, today announced financial results for its second quarter ended June 30, 2024. 

Second Quarter 2024 Financial Summary

•Revenue of $60.1 million, compared to $65.8 million in the second quarter of 2023. Revenue for the first six months of 2024 was $120.8 million, compared to $123.5 million for the first half of 2023.

•GAAP gross margin of 80.0%; non-GAAP gross margin of 80.9% as a result of continued focus on operational execution of business model goals in spite of near-term volatility in the market.

•GAAP net income of $9.5 million (15.8% of revenue), or $0.13 per diluted share, compared to net income of $11.6 million (17.7% of revenue) or $0.15 per diluted share in the second quarter of 2023.

•Non-GAAP net income of $13.2 million (22.0% of revenue), or $0.18 per diluted share (non-GAAP EPS) compared to non-GAAP net income of $14.5 million (22.1% of revenue) or $0.19 per diluted share in the second quarter of 2023.

•The Company returned $16.3 million to investors, having repurchased 844 thousand shares at an average price of $14.02 per share for a total of $11.8 million and having paid $4.5 million in cash dividends in the quarter.

•The Board of Directors approved a quarterly cash dividend of $0.06 per share, payable September 3, 2024, to stockholders of record at the close of business on August 15, 2024.

A reconciliation between GAAP and non-GAAP information is contained in the financial statements below.

“Consistent with our prior comments and expectations, the North American service provider market remains volatile, impacting our quarter-to-quarter visibility,” commented Dhrupad Trivedi, A10 Network’s President and Chief Executive Officer. “While elongated sales cycles have slowed service provider revenue, we continue to believe that we have not lost those customer opportunities to competitors or cancellations, and demand for our security-led solutions remains robust. The Enterprise segment continues to grow in line with our stated strategy. During the second quarter, Enterprise revenue increased 25% and year-to-date, Enterprise revenue was up 7%. We continue to increase our research and development investments, focused on enterprise-targeted solutions and capitalizing on AI-driven market potential, to better position A10 to capture growth opportunities in the future.”

“Despite the macro challenges, we continued to deliver bottom-line results in-line with expectations while returning significant capital to shareholders,” added Trivedi. “We believe our business model enables solid and consistent profitability, and our revenue diversification positions A10 to navigate challenging market conditions.”

Forward-Looking Statements

This press release contains “forward-looking statements,” including statements regarding our quarterly dividend payments and stock repurchase program, strategy, growth, customer opportunities, demand, positioning, profitability, revenue and expectations for 2024, market trends, investments and return of capital. 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 any unforeseen need for capital which may require us to divert funds we may have otherwise used for the dividend program or stock repurchase program, which may in turn negatively impact our ability to administer the quarterly dividends or the repurchase of our common stock; 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 February 29, 2024. 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, Adjusted EBITDA and Adjusted EBITDA margin. 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) restructuring expense, (iii) cyber incident remediation expense, (iv) one-time tax planning expense, (v) one-time legal expense and (vi) income tax effect of non-GAAP items (i) to (v) listed above. 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 non-GAAP gross profit as our GAAP gross profit excluding (i) stock-based compensation and related payroll tax, (ii) restructuring expense and (iii) cyber incident remediation expense. We define non-GAAP gross margin as our non-GAAP gross profit 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) restructuring expense, (iii) cyber incident remediation expense, (iv) one-time tax planning expense and (v) one-time legal expense. We define non-GAAP operating income as our GAAP income from operations excluding (i) stock-based compensation and related payroll tax, (ii) restructuring expense, (iii) cyber incident remediation expense, (iv) one-time tax planning expense and (v) one-time legal expense. We define non-GAAP operating margin as our non-GAAP operating income divided by our GAAP revenue. 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 income taxes, (iv) stock-based compensation and related payroll tax, (v) restructuring expense, (vi) cyber incident remediation expense, (vii) one-time tax planning expense and (viii) one-time legal expense. We define Adjusted EBITDA margin as our Adjusted EBITDA divided by our GAAP revenue.

Non-GAAP financial measures are presented for supplemental informational purposes only for understanding the company's operating results.

Our adjusted net income and earnings per share may not be comparable to similarly titled measures of another company because companies may not all calculate adjusted net income and earnings per share in the same manner.

Q2 2024 Financial Results & Commentary July 30, 2024

Cautionary Statements & Disclosures This presentation and the accompanying oral presentation contain “forward-looking” statements that are based on our management’s beliefs and assumptions, including statements regarding our future financial performance, strategy, demand, positioning, capital allocation strategy and value creation, and market and technology trends. 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 any unforeseen need for capital which may require us to divert funds we may have otherwise used for the dividend program or stock repurchase program, which may in turn negatively impact our ability to administer the quarterly dividends or the repurchase of our common stock; 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 February 27, 2023. 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. 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 excluding: (i) stock-based compensation and related payroll tax, (ii) restructuring expense, (iii) cyber incident remediation expense, (iv) one-time tax planning expense, (v) one-time legal expense, (vi) capitalized project impairment expense and (vii) income tax effect of non-GAAP items (i) to (vi) listed above. 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 non-GAAP gross profit as our GAAP gross profit excluding (i) stock-based compensation and related payroll tax, (ii) restructuring expense and (iii) cyber incident remediation expense. We define non-GAAP gross margin as our non-GAAP gross profit 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) restructuring expense, (iii) cyber incident remediation expense, (iv) one-time tax planning expense and (v) one-time legal expense. We define non-GAAP operating income as our GAAP income from operations excluding (i) stock-based compensation and related payroll tax, (ii) restructuring expense, (iii) cyber incident remediation expense, (iv) one-time tax planning expense, (v) one-time legal expense and (vi) capitalized project impairment expense . We define non-GAAP operating margin as our non-GAAP operating income divided by our GAAP revenue. 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 income taxes, (iv) stock-based compensation and related payroll tax, (v) restructuring expense, (vi) cyber incident remediation expense, (vii) one-time tax planning expense, (viii) one-time legal expense and (ix) capitalized project impairment expense. We define Adjusted EBITDA margin as our Adjusted EBITDA divided by our GAAP revenue. A reconciliation between GAAP and non-GAAP financial measures can be found in the appendix to this document and in the accompanying financial results press release.
