Conflict Minerals Report

For the Year Ended December 31, 2016

This Conflict Minerals Report (“Report”) for the year ended December 31, 2016 has been prepared in accordance with Rule 13p-1 of the Securities Exchange Act of 1934 (“Rule 13p-1”). Certain terms in this Report are defined in Rule 13p-1, and the reader is referred to this Rule and to Release No. 34-67716 issued by the Securities and Exchange Commission on August 22, 2012 for these definitions.

Conflict Minerals, as defined under Rule 13p-1, include tin, tantalum, tungsten or gold, or their derivatives. Maxwell Technologies, Inc. ("Maxwell" or the "Company") manufactures, or contracts to manufacture, the following products containing Conflict Minerals necessary to the functionality or production of the products:

• Ultracapacitors, are energy storage devices that possess a unique combination of high power density, extremely long operational life and the ability to charge and discharge very rapidly. Maxwell's ultracapacitor cells, multi-cell packs and modules provide highly reliable energy storage and power delivery solutions for applications in multiple industries, including automotive, bus, rail and truck in transportation, grid energy storage and renewable wind energy solutions; and

• High-Voltage Capacitors, Maxwell's CONDIS® high-voltage capacitors are designed and manufactured to perform reliably for decades in all climates. These products include grading and coupling capacitors and electric voltage transformers that are used to ensure the safety and reliability of electric utility infrastructure and other applications involving transport, distribution and measurement of high-voltage electrical energy.

In accordance with Rule 13p-1, Maxwell undertook due diligence to determine the source and chain of custody of Conflict Minerals necessary to the production or functionality of its products. In conducting its due diligence, Maxwell applied the OECD Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas (“OECD Due Diligence Guidance”), an internationally recognized due diligence framework. The objective of this due diligence is to determine whether Conflict Minerals originated in the Democratic Republic of the Congo or an adjoining country (collectively defined as the “Covered Countries”), and if so, whether sourcing practices directly or indirectly financed or benefited Armed Groups in the Covered Countries. Under Rule 13p-1, “DRC conflict free” refers to products for which sourcing practices did not directly or indirectly finance or benefit Armed Groups in the Covered Countries. In this Report, Maxwell uses the term “conflict-free” more broadly to refer to suppliers, smelters and refiners that source Conflict Minerals without funding conflict as described above.

Maxwell exercised reasonable due diligence to determine the source and chain of custody of its Conflict Minerals in accordance with the OECD Due Diligence Guidance. These procedures included the following:

• Oversight of the Company’s compliance with Rule 13p-1, including the design and execution of a due diligence plan, by a steering committee which included executive leadership;

• Maintained a Conflict Mineral Policy which is published on Maxwell's publicly-available internet site;

• Determined in-scope suppliers of materials and components that contain or may contain Conflict Minerals and conducted supply chain surveys to assess the usage of Conflict Minerals and to identify the smelter and refiners of Conflict Minerals in the Company’s supply chain;

• Utilized a third party software program to assist with the execution of supplier surveys and risk assessment procedures under the Company's conflict minerals due diligence program;

• Reviewed and evaluated responses received from in-scope suppliers for reasonableness and conducted several rounds of follow up on incomplete responses;

• Evaluated smelting and refining facilities identified in the Company’s supply chains for Conflict Minerals against the list of smelters and refiners that have been designated as “conflict-free” under the Conflict-Free Smelter Program sponsored by the Electronics Industry Citizen Coalition and the Global e-Sustainability Initiative ("EICC-GeSI"); and,

• Assigned a risk score to each supplier of Conflict Minerals based on mineral sourcing practices in order to understand the risk of conflict-sourcing in Maxwell's products and to determine further due diligence measures to be performed.

For the supply chain surveys described above, Maxwell conducted these surveys utilizing the Conflict Mineral Reporting Template developed by EICC-GeSI. All responses received from suppliers were reviewed and evaluated for reasonableness and

completeness and all identified smelters and refiners were checked against the EICC-GeSI list of certified “conflict-free” smelters and refiners to determine whether the facility has been independently certified as “conflict-free”. To date, not all suppliers have responded to Maxwell’s survey, and for those suppliers which did respond, some responses were incomplete in that not all of the indirect suppliers underlying Maxwell’s direct suppliers have provided complete location of origin information for Conflict Minerals. Therefore, the source and chain of custody information for Conflict Minerals included in Maxwell’s products is currently incomplete. Further, not all known smelters and refiners have been designated as “conflict-free” under the EICC-GeSI Conflict Free Smelter Program.

Below is a summary of the number of suppliers surveyed for each product line and the responses received to date:

• For Ultracapacitor products, 13 suppliers were surveyed and approximately 77% of suppliers have provided a survey response.

• For High-Voltage Capacitor products, 3 suppliers were surveyed and 67% of suppliers have provided a survey response.

Identified smelters and refiners and countries of origin for Conflict Minerals included in the Company’s products, to the extent known, are listed in Appendix A to this Report.

For the 2017 compliance period, Maxwell plans to continue to execute due diligence measures to determine the source and chain of custody of Conflict Minerals contained in its products.
