Due Diligence Framework and Overview

We undertook due diligence on the source and chain of custody of the tantalum, tin, tungsten, and gold (“Conflict Minerals” or “3TG”) that are necessary to the functionality or production of products manufactured or contracted to be manufactured by us. We designed our due diligence to conform to an internationally recognized due diligence framework, the Organization for Economic Co-operation and Development (OECD) Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas, Third Edition, and related supplements (“OECD Framework”).

The OECD Framework divides the entire Conflict Mineral supply chain into upstream and downstream entities. An upstream entity is within the Conflict Mineral supply chain from the mine to the smelter or refiner and includes miners, local traders, and exporters from the country of mineral origin, international concentrate traders, mineral processors, smelters, and refiners. A downstream entity is within the Conflict Mineral supply chain from when the mineral leaves the smelter or refiner to when it arrives at the retailer and includes metal traders and exchanges, component manufacturers, product manufacturers, original equipment manufacturers, and retailers.

The Company is a downstream entity and is typically several tiers removed from the smelter or refiner and the origin of the Conflict Minerals present in our supply chain for Covered Products. We have limited visibility beyond our direct suppliers to entities within the supply chain. Therefore, we rely principally on our direct suppliers to provide us with sourcing information for the Conflict Minerals present in their supply chain.

We conduct a portion of our due diligence using tools and relying on information provided by the Responsible Minerals Initiative (“RMI”), an industry group that works to address Conflict Minerals issues within supply chains. We use the Conflict Minerals Reporting Template (“CMRT”) to facilitate the collection of information on the source of Conflict Minerals. We also rely on RMI’s Responsible Minerals Assurance Process (“RMAP”), which uses an independent third-party assessment of smelter and refiner management systems and sourcing practices for Conflict Minerals to validate conformance with RMAP standards.

Due Diligence Process

The OECD Framework provides a five-step framework for risk-based due diligence in the Conflict Mineral supply chain. Set forth below, we disclose the actions we took to exercise due diligence under this framework for the sourcing of Conflict Minerals we used or may have used when manufacturing or contracting to manufacture the Covered Products.

Step 1 - Establish strong company management systems

RCOI and Due Diligence Measures Performed

The Company’s Reasonable Country of Origin Inquiry (“RCOI”) was designed to determine whether the Conflict Minerals, which are necessary to the functionality or production of a product manufactured (or contracted to be manufactured) by the Company, originated in the Covered Countries. The Company performed a good faith, risk-based, global scoping exercise to identify suppliers of Covered Products that were considered in-scope and therefore subject to RCOI in the 2023 calendar year. Through communications with these suppliers, the Company attempted to identify smelters and refiners of Conflict Minerals that are or may be utilized in the Covered Products during the reporting period.

The Company’s RCOI and due diligence employed a combination of measures to determine whether the necessary Conflict Minerals in the Covered Products originated from the Covered Countries. The Company identified suppliers of commodity groups with high potential of containing Conflict Minerals. In other cases, the materials supplied were analyzed by other means. All identified first-tier suppliers of Conflict Minerals were surveyed to ascertain for each Conflict Mineral (a) the smelter or refiner where it was processed, (b) its country of origin and (c) the mine or location of origin, using the CMRT and RMAP.

The Company strives for participation of all In-Scope Suppliers but did not receive responses from all of such suppliers and, in some cases, responses were incomplete or did not appear to be accurate, even after reasonable follow-up. Furthermore, the majority of our suppliers that did provide names of smelters and refiners and country of origin information, did so only on an entity-wide basis without distinguishing between 3TG purchased for goods supplied to Gentherm and 3TG purchased for other purposes. Because we did not receive full and complete responses covering products supplied to Gentherm from every supplier in every case, we were unable to determine the country of origin of Conflict Minerals for some of the Covered Products or whether such Conflict Minerals for Covered Products were from recycled or scrap sources.

Smelters and Refiners

Gentherm identified 549 suppliers of Covered Products that were considered in-scope and subject to RCOI in the 2023 calendar year (the “In-Scope Suppliers”). These In-Scope Suppliers covered approximately $490 million, representing over 74%, of our total material spending in 2023. Out-of-scope suppliers included those suppliers providing exclusively products that were evaluated and determined to contain no metallic content or to be of de minimus spend. We received CMRTs or similar supporting data covering over 95% of the in-scope material spend in 2023.

The smelters and refiners that our suppliers identified in the CMRTs submitted to us for this reporting year are provided in a listing in Attachment A to this report. Our submitted supplier CMRTs included two smelters or refiners that were not identified on RMI’s Smelter Reference List or related materials, but are nonetheless included in Attachment A (with Smelter Country noted as “Unknown”). As noted above, the majority of the CMRTs we received from our suppliers were made on an entity-wide basis, rather than on a product-level basis. Therefore, we believe the list of smelters in Attachment A both omits smelters that are in the Company’s supply chain for Covered Products and includes smelters that are not in the Company’s supply chain for Covered Products.

Due Diligence Enhancements

We consider ongoing compliance improvements during each reporting period to (1) increase our ability to determine the country of origin of the Conflict Minerals and the facilities used to mine and refine the Conflict Minerals used in, and necessary to, the functionality or production of our products, including by obtaining more Company-specific product information, and (2) further mitigate the risks that necessary Conflict Minerals contained in the Company’s products finance or benefit armed groups in Covered Countries. Additional steps may include the following:
