Item 4.02
Non-Reliance on Previously Issued Financial Statements or a Related Audit Report or Completed Interim Review

Results of the Audit Committee Investigation
A10 Networks (the “Company”) announced today that the Audit Committee of its Board of Directors has completed its internal investigation previously disclosed on January 30, 2018. The Audit Committee conducted the investigation with the assistance of outside counsel, as well as independent counsel. Counsel retained forensic accountants to assist with their work.
On July 2, 2018, as a result of facts identified during the investigation, the Audit Committee, in consultation with the Company’s management, concluded that the Company’s previously issued consolidated financial statements and other financial information, and the related report of its independent registered public accounting firm, each as contained in its Annual Report on Form 10-K for the fiscal year ended December 31, 2016, and its condensed consolidated financial statements contained in its Quarterly Reports on Form 10-Q for the quarters ended September 30, 2016 and March 31, 2017 should no longer be relied upon and should be restated, because of errors in those financial statements. The errors generally concerned the timing of the recognition of revenue in a limited number of sale transactions between the Company and its resellers and distributors. Revenue on certain sale transactions was recognized prematurely, as it was determined that the reseller’s or distributor’s price was not fixed or determinable, or that collectability was not reasonably assured, because the reseller’s or distributor’s payment to the Company was contingent on resale of the product or the transaction included extended payment terms beyond the Company’s customary terms.
As a result, the Company’s Total Revenue was overstated by approximately $1 million for the three months ended September 30, 2016, overstated by approximately $3 million for the year ended December 31, 2016, and understated by approximately $4 million for the three months ended March 31, 2017. The Company’s Net Loss was understated by approximately $1 million for the three months ended September 30, 2016, understated by approximately $2 million for the year ended December 31, 2016, and overstated by approximately $3 million for the three months ended March 31, 2017. As part of the restatement process, the Company is continuing to assess the adjustments identified above and will assess any other potential items for correction as needed.
In addition, the Company is evaluating the impact of the errors identified in the investigation on its internal control over financial reporting and disclosure controls and procedures, and expects to report one or more material weaknesses in internal control over financial reporting related to this matter and to report that its disclosure controls and procedures were not effective. The Company is evaluating, has begun to implement and will continue to implement remedial measures identified by the investigation.
The Audit Committee has discussed the matters disclosed in this Item 4.02(a) with the Company’s independent registered public accounting firm.
