Description of Business and Significant Accounting Policies | Description of Business and Summary of Significant Accounting Policies Description of Business A10 Networks, Inc. (together with our subsidiaries, the “Company”, “we”, “our” or “us”) was incorporated in California in 2004 and reincorporated in Delaware in March 2014. We are headquartered in San Jose, California and have wholly-owned subsidiaries throughout the world including Asia and Europe. We are a leading provider of secure application solutions and services that enable a new generation of intelligently connected companies with the ability to continuously improve cyber protection and digital responsiveness across dynamic Information Technology (“IT”) and network infrastructures. Our product portfolio seeks to address many of the cyber protection challenges and solution requirements. The portfolio consists of six secure application solutions; Thunder Application Delivery Controller (“ADC”), Lightning Application Delivery Controller (“Lightning ADC”), Thunder Carrier Grade Networking (“CGN”), Thunder Threat Protection System (“TPS”), Thunder SSL Insight (“SSLi”) and Thunder Convergent Firewall (“CFW”), and two intelligent management and automation tools; Harmony Controller and aGalaxy TPS. Our solutions are available in a variety of form factors, such as optimized hardware appliances, bare metal software, containerized software, virtual appliances and cloud-native software. Our customers include leading service providers (cloud, telecommunications, multiple system operators, cable), government organizations, and enterprises. We derive revenue from two sources: (i) products revenue, which includes hardware, perpetual software license and subscription offerings, which include term-based license agreements; and (ii) services revenue, which includes post contract support (“PCS”), professional services, training and software-as-a-service offerings. Revenue for term-based license agreements is recognized at a point in time when the Company delivers the software license to the customer and over time once the subscription term has commenced. For our software-as-a-service offerings, our customers do not take possession of the Company’s software but rather we provide access to the service via a hosting arrangement. Revenue in these arrangements is recognized over time as the services are provided. A substantial portion of our revenue is from sales of our products and services through distribution channel partners, such as resellers and distributors. Our customers predominantly purchase PCS services in conjunction with purchases of our products. We recognize services revenue ratably over the term of the PCS contract, which is typically one year, but can be up to seven years. We sell our products globally to service providers and enterprises that depend on data center applications and networks to generate revenue and manage operations efficiently. We report two customer verticals: service providers and enterprises, and we report customer revenues in three broad geographic regions: the Americas, APJ and EMEA regions. The Americas region comprises the United States and other countries in the Americas (excluding the United States). The APJ region comprises Japan and other countries in Asia Pacific. The EMEA region comprises Europe, Middle East and Africa. We believe this geographic revenue view is consistent with how we evaluate our financial performance. Our end-customers operate in a variety of industries, including telecommunications, technology, industrial, retail, financial, gaming, education and government. Since inception, our customer base has grown rapidly. We sell substantially all of our solutions through our high-touch sales organization as well as distribution channel partners, including distributors, value-added resellers and system integrators, and fulfill nearly all orders globally through such partners. We believe this sales approach allows us to obtain the benefits of channel distribution, such as expanding our market coverage, while still maintaining face-to-face relationships with our end-customers. We outsource the manufacturing of our hardware products to original design manufacturers. We perform quality assurance and testing at our San Jose, Taiwan and Japan distribution centers, as well as at our manufacturers’ locations. Basis of Presentation The accompanying unaudited condensed consolidated financial statements include those of A10 Networks, Inc. and its subsidiaries after elimination of all intercompany accounts and transactions. We have prepared the accompanying unaudited condensed consolidated financial statements pursuant to the rules and regulations of the United States Securities and Exchange Commission (the “SEC” or the “Commission”). As permitted under these rules and regulations, we have condensed or omitted certain financial information and footnote disclosures we normally include in our annual consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The unaudited condensed consolidated balance sheet as of December 31, 2023 has been derived from our audited financial statements, which are included in our 2023 Annual Report on Form 10-K for the year ended December 31, 2023 on file with the SEC (the “2023 Annual Report”). These financial statements have been prepared on the same basis as our annual financial statements and, in management’s opinion, reflect all adjustments consisting only of normal recurring adjustments that are necessary for a fair presentation of our financial information. Our interim period operating results do not necessarily indicate the results that may be expected for any other interim period or for the full fiscal year. These financial statements and accompanying notes should be read in conjunction with the financial statements and accompanying notes thereto in the 2023 Annual Report. Use of Estimates The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Those estimates and assumptions affect revenue recognition and deferred revenue, the allowance for credit losses for potential uncollectible amounts, the sales return reserve, the valuation of inventory, the fair value of marketable securities, contingencies and litigation, accrued liabilities, deferred commissions and the determination of fair value of stock-based compensation. These estimates are based on information available as of the date of the condensed consolidated financial statements, therefore, actual results could differ from management’s estimates. Significant Accounting Policies The Company’s significant accounting policies are disclosed in Part II – Item 8, “Financial Statements and Supplementary Data” of the 2023 Annual Report filed with the SEC on February 29, 2024. There have been no material changes to the Company’s significant accounting policies during the three and six months ended June 30, 2024. Concentration of Credit Risk and Significant Customers Financial instruments that potentially subject us to concentrations of credit risk consist of cash, cash equivalents, marketable securities and accounts receivable. Our cash, cash equivalents and marketable securities are held and invested in high-credit quality financial instruments by recognized financial institutions and are subject to minimum credit risk. Our accounts receivable are unsecured and represent amounts due to us based on contractual obligations of our customers. We mitigate credit risk in respect to accounts receivable by performing periodic credit evaluations based on a number of factors, including past transaction experience, evaluation of credit history and review of the invoicing terms of the contract. We generally do not require our customers to provide collateral to support accounts receivable. Significant customers, including distribution channel partners and direct customers (end-customers), are those which represent 10% or more of our total revenue for each period presented or our gross accounts receivable balance as of each respective balance sheet date. Revenues from our significant end-customers as a percentage of our total revenue are as follows:
|  | Three Months Ended June 30, |  | Six Months Ended June 30,
Customers |  | 2024 |  | 2023 |  | 2024 |  | 2023
Customer A |  | 14% |  | 25% |  | 13% |  | 20%
As of June 30, 2024, one customer accounted for 43% of our total gross accounts receivable. As of December 31, 2023, one customer accounted for 19% of our total gross accounts receivable. Recent Accounting Standards Not Yet Adopted In November 2023, the Financial Accounting Standards Board, or the FASB, issued Accounting Standards Update, or ASU, 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires public entities to disclose information about their reportable segments’ significant expenses and other segment items on an interim and annual basis. Public entities with a single reportable segment are required to apply the disclosure requirements in ASU 2023-07, as well as all existing segment disclosures and reconciliation requirements in ASC 280, on an interim and annual basis. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, and for interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. We do not expect the adoption of this accounting standard to have an impact on our consolidated financial statements, but will require certain additional disclosures. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires public entities, on an annual basis, to provide disclosure of specific categories in the rate reconciliation, as well as disclosure of income taxes paid disaggregated by jurisdiction. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. We are currently evaluating the impact of adopting ASU 2023-09. There have been no other recent accounting pronouncements, changes in accounting pronouncements or recently adopted accounting guidance during the three and six months ended June 30, 2024 that are of significance or potential significance to us.
