A10 Networks (NYSE:ATEN), a leading provider of secure application services and solutions, today announced financial results for its second quarter ended June 30, 2021.

Second Quarter 2021 Financial Summary

Revenue of $59.2 million, up 12.7% year-over-year.
Improving commercial execution combined with favorable market conditions drove 20% growth in the Americas year-over-year; Japan normalized as expected.
Deferred revenue of $116.3 million, up 10.8% year-over-year.
GAAP gross margin of 77.0%; non-GAAP gross margin of 77.9% as the company navigated short-term input cost pressures.
GAAP net income of $6.6 million, or $0.08 per diluted share, compared with net income of $3.8 million, or $0.05 per diluted share in the second quarter of 2020.
Non-GAAP net income of $10.5 million, or $0.13 per diluted share compared with non-GAAP net income of $7.1 million, or $0.09 per diluted share in the second quarter of 2020.
Adjusted EBITDA of $13.2 million compared to $9.8 million in the second quarter of 2020.

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

"Our focus on customer-centric product innovation and on driving improvements in commercial execution is beginning to deliver results, with consolidated revenue growing double-digits in the second quarter and EBITDA growing faster than that rate," said Dhrupad Trivedi, President and Chief Executive Officer of A10 Networks. "We gained market share, adding new customers and expanding our security-led sales with existing customers. As expected, Japan again grew year-over-year during the quarter. Our customer engagements, strength of funnel and improving execution reinforce our confidence in full year growth targets while building a diversified customer base for the future."

"We continue to deliver on our strategic goal to deliver leading innovative solutions to the market," continued Trivedi. "We grew product revenue, which is a leading indicator of future recurring revenue, by 17.6% year-over-year. Year-to-date, recurring revenue has grown faster than our consolidated revenue, and our deferred revenue reached an all-time high, demonstrating our ability to sell differentiated solutions that are meeting the security challenges of today's world. The growth, combined with an increasingly favorable sales mix, greater contribution of recurring revenue and discipline related to our cost structure is driving significant expansion of our profitability. Our GAAP net income nearly doubled on 12.7% revenue growth, and we generated more than $17.2 million in cash from operating activities during the quarter."

Based on improved visibility, management today provided guidance for the third quarter. Management now expects third quarter revenue of $60.6 to $63.4 million, with the bottom-line growing at a faster rate than the top-line.

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 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.

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) non-recurring expenses associated with the litigation settlement and internal investigation expense, (iv) global distribution center transition expense, 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 (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, (iii) non-recurring expenses associated with the litigation settlement and internal investigation expense, (iv) global distribution center transition expense, 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 payroll tax, (ii) amortization expense related to acquisition, (iii) non-recurring expenses associated with the litigation settlement and internal investigation expense, (iv) global distribution center transition expense, and (v) non-recurring facilities 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 for income taxes, (v) stock-based compensation and related payroll tax, (vi) litigation settlement and internal investigation expense, (vii) global distribution center transition expense, 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.
