Section 1 – Conflict Minerals Disclosure

Item 1.01 Conflict Minerals Disclosure and Report

Quantum Corporation (“Quantum”) has evaluated its current products and determined that certain products we manufacture or contract to manufacture contain tin, tungsten, tantalum and/or gold (“3TG”). Based on the outcome of our due diligence procedures, we have filed a Conflict Minerals Report herewith.

Reasonable Country of Origin Inquiry (RCOI)

Following our initial determination that certain of our hardware products contain components that contain 3TG minerals, Quantum conducted an RCOI to determine which components contain 3TG minerals and whether such 3TG minerals originated in the Democratic Republic of the Congo and adjoining countries (the “Covered Countries”). Our RCOI was based on a survey of our direct suppliers of parts, components and assemblies containing conflict minerals. We have identified over 200 direct suppliers that supply components for our products that may contain 3TG minerals. We requested that each of these 200 suppliers complete the EICC GeSI conflict minerals reporting template. We do not have a direct relationship with any of the smelters or refiners of the 3TG materials. Accordingly, we rely on our suppliers to provide us with information about the source of conflict minerals contained in the components supplied to us based on the EICC GeSI conflict minerals reporting template. Our direct suppliers are similarly reliant upon information provided by their suppliers. Many of the largest suppliers are also SEC registrants and subject to Rule 13p-1.

Over 75% of our suppliers responded. Based on those responses, Quantum determined that 3TG minerals present in certain of its products may have originated in the Covered Countries and were not from scrap or recycled sources. Therefore, in accordance with Rule 13p-1, Quantum proceeded to engage in due diligence regarding the sources and chain of custody of its 3TG minerals and has completed a Conflict Minerals Report, filed herewith.
