Section 1 – Conflict Minerals Disclosure

Item 1.01 Conflict Minerals Disclosure and Report

With respect to the reporting period from January 1, 2015 to December 31, 2015, Qualys, Inc. (“Qualys” or the “Company”) conducted a reasonable country of origin inquiry and additional due diligence designed to conform with the Organisation for Economic Co-operation and Development (“OECD”) Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas, including the related supplements on gold, tin, tantalum and tungsten (the “Framework”), in order to determine whether the products that we manufacture which contain any gold, columbite-tantalite (coltan), cassiterite and wolframite, including their derivatives (“Conflict Minerals”) originate from the Democratic Republic of Congo, the Republic of Congo, the Central African Republic, South Sudan, Uganda, Rwanda, Burundi, Tanzania, Zambia and Angola (collectively, the “Covered Countries”). Based on these due diligence efforts, we have reason to believe that certain Conflict Minerals contained in our products may have originated in the Covered Countries and may not be Conflict Minerals from recycled or scrap sources. However, we do not have sufficient information to conclusively determine the countries of origin of the Conflict Minerals contained in our products or whether the Conflict Minerals in our products are from scrap or recycled sources. We therefore conducted due diligence on the source and chain of custody of these Conflict Minerals and have prepared the Conflict Minerals Report attached hereto as Exhibit 1.01.
