Section 1 - Conflict Minerals Disclosure

Item 1.01 Conflict Minerals Disclosure and Report

The Company has filed a Conflict Minerals Report filed as Exhibit 1.01 hereto and it is publicly available at https://investors.a10networks.com/corporate-governance/governance-documents/default.aspx. The content of our website as referred to in this Form SD is included for general information only and is not incorporated by reference into this Form SD.

Conflict Minerals Disclosures

(a)The Company conducted a Reasonable Country of Origin Inquiry (“RCOI”) as required by Item 1.01(a) of Form SD. The RCOI began with a multi-department initiative that scoped and evaluated the Company’s product line to determine which suppliers provide the Company with manufactured or contracted to be manufactured products. The Company then looked on a product-by-product level to determine which of these products were most likely to contain Conflict Minerals (as defined by the U.S. Securities and Exchange Commission) that are “necessary to the functionality or production” of the product, or are otherwise sourced from recycled or scrap materials. Suppliers of such products (other than those sourced from recycled or scrap materials) were next identified and surveyed using the basic EICC/GeSI Conflict Minerals Reporting Template or, where appropriate, a custom-designed form. Follow-up was undertaken with those suppliers who provided incomplete forms or were otherwise non-responsive. The Company then evaluated the information provided from suppliers to assess completeness and reliability of the data collected. On the basis of this inquiry and evaluation, the Company has no reason to believe that the Conflict Minerals contained in its products originated in the Democratic Republic of Congo or adjoining countries (the “Covered Countries”).

(b)On the basis of its RCOI undertaking, the Company has no reason to believe that its necessary Conflict Minerals may have originated in the Covered Countries. Given that the results of its RCOI efforts were inconclusive, the Company proceeded to the due diligence stage of the inquiry as required by Form SD and has filed herewith a Conflict Minerals Report, which is attached as Exhibit 1.01 to this Form SD.

Item 1.02 Exhibits

A copy of the Company’s Conflict Minerals Report is provided as Exhibit 1.01 hereto.
