If the subject report could not be filed without unreasonable effort or expense and the registrant seeks relief pursuant to Rule 12b-25(b), the following should be completed. (Check box if appropriate)


☐       (a)   

The reason described in reasonable detail in Part III of this form could not be eliminated without unreasonable effort or expense;



The subject annual report, semi-annual report, transition report on Form 10-K, Form 20-F, Form 11-K,

Form N-SAR or Form N-CSR, or portion thereof, will be filed on or before the fifteenth calendar day following the prescribed due date; or the subject quarterly report or transition report on Form 10-Q or subject distribution report on Form 10-D, or portion thereof, will be filed on or before the fifth calendar day following the prescribed due date; and


   (c)    The accountant’s statement or other exhibit required by Rule 12b-25(c) has been attached if applicable.




State below in reasonable detail why Forms 10-K, 20-F, 11-K, 10-Q, 10-D, N-SAR, N-CSR, or the transition report or portion thereof, could not be filed within the prescribed time period.

A10 Networks, Inc. (“A10” or the “Company”) has determined that it is unable to file its Quarterly Report on Form 10-Q for the quarter ended June 30, 2018 (the “Form 10-Q”) by August 9, 2018, the original due date for such filing, without unreasonable effort or expense due to the circumstances described below.

As previously announced in the Form 8-K filed by the Company with the Securities and Exchange Commission (“SEC”) on July 2, 2018 (the “Restatement 8-K”), the Audit Committee of the Company’s Board of Directors completed an internal investigation into certain revenue recognition and internal control matters for the period beginning with the fourth quarter of 2015 and ending with the fourth quarter of 2017, and, 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 Company is continuing to evaluate 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 as of December 31, 2017.

As a result of these events, the Company has been unable to complete its preparation and review of the Form 10-Q in time to file within the five-day extension period provided under Rule 12b-25(b). The Company is working to complete the preparation of its financial statements for the year ended December 31, 2017, as well as the quarters ended March 31, 2018 and June 30, 2018, as soon as practicable. Due to the procedures required before such process can be completed, the Company is not able to predict at this time the exact dates for such filings, but currently expects to be able to make such filings in the third quarter of 2018. The Company also expects to provide during the third quarter an update on its business and financial performance in the first half of 2018.
