Semtech Corporation
Conflict Minerals Report for the Year Ended December 31, 2025
This Conflict Minerals Report (this “Report”) of Semtech Corporation (“Semtech”) for calendar year 2025 is filed in accordance with Rule 13p-1 under the Securities Exchange Act of 1934 (“Rule 13p-1”). Numerous terms in this Report are defined in Rule 13p-1 and in the Specialized Disclosure Report on Form SD and the reader is referred to those sources for such definitions. Unless the context otherwise requires, “Semtech” “we,” “our” and “us” refers to Semtech Corporation and its consolidated subsidiaries.
Semtech has determined that conflict minerals, which are defined as cassiterite, columbite-tantalite (coltan), gold, wolframite and their derivatives, which are limited to tantalum, tin, or tungsten (“Conflict Minerals” or “3TG”), are necessary to the functionality and/or production of many of our manufactured products. We undertook a reasonable country of origin inquiry (“RCOI”) regarding the conflict minerals in our manufactured products. This RCOI was reasonably designed to determine whether any of the conflict minerals in our manufactured products originated in the Democratic Republic of the Congo or an adjoining country (the “Covered Countries”) and whether any of the conflict minerals may be from recycled or scrap sources. Semtech also exercised due diligence on the source and chain of custody of the conflict minerals.
This Report is not audited, as Rule 13p-1 and current guidance of the Securities and Exchange Commission (the “SEC”) provide that if the registrant is not declaring products as “DRC Conflict Free,” the Report is not subject to an independent private sector audit.

Reasonable Country of Origin Inquiry and Due Diligence Process
Semtech as a purchaser is many steps removed from the mining of the conflict minerals that are necessary to the functionality or production of our semiconductor or IoT hardware products. We do not purchase raw ore or unrefined conflict minerals, and we do no purchasing in the Covered Countries. We relied upon our suppliers to provide information on the origin of the conflict minerals contained in components and materials supplied to us, including sources of conflict minerals that are supplied to them from sub-tier suppliers. Our suppliers are expected to provide the conflict minerals sourcing information to us per our Conflict Minerals Policy and the Semtech Policy Regarding Conflict Metals Procured from Conflict Areas.
For this Report, we performed an analysis of our products and product components, and the role that suppliers play throughout our manufacturing and product delivery processes. We defined the scope of our conflict minerals due diligence by identifying and reaching out to our current suppliers that provide components or engage in manufacturing activities that are likely to contain conflict minerals. We adopted the standard Conflict Minerals reporting template (“CMRT”) established by RMI and launched our conflict minerals due diligence communication survey to these suppliers, who are foundries, materials, and turnkey and assembly service suppliers.
We designed our due diligence measures to be in conformity, in all material respects, with the framework in the Organization for Economic Co-operation and Development Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas and related supplements for gold, tin, tantalum and tungsten (“OECD Framework”).
Summarized below are the design components of our conflict minerals program as they relate to the five-step framework set forth in the OECD Framework:
1. Establish Strong Company Management Systems
•Adopted a Conflict Minerals Policy which provides that Semtech will seek to ensure, to the extent reasonably practicable, that the products within our supply chain are not fabricated, assembled nor manufactured with metals whose origin traces back to any “conflict areas” as identified by the Dodd- Frank Wall Street Reform and Consumer Protection Act of 2010.
•Established internal Conflict Minerals Program team, led by our Quality & Compliance team and supported by a cross-functional team consisting of representatives from Operations, Supply Chain, Legal, Finance and Internal Audit functions.
•Communicated with our direct suppliers and requested that they execute the CMRT annually.
•Required that our suppliers and contract manufacturers implement the Responsible Business Alliance’s (“RBA”) Code of Conduct, which includes an obligation to conduct due diligence regarding Conflict Minerals.
•Incorporated vendor qualification requirements related to conflict minerals in our standard qualification process so that current and future suppliers are obligated to participate in a supply chain survey and related due diligence activities.
•Established a company-wide, third-party managed, grievance mechanism (Ethico), that serves as Semtech’s anonymous procedure for employee submissions of concerns regarding ethical violations or questionable accounting or auditing matters, including concerns with violations of Semtech’s Conflict Minerals Policy.
2. Identify and Assess Risks in Our Supply Chain
•Identified direct suppliers that supply products to Semtech that may contain conflict minerals;
•Conducted a supply-chain survey with direct suppliers using the CMRT to identify the smelters and refiners which contribute refined conflict minerals to Semtech products.
•Compared the smelters and refiners identified by direct suppliers via the supply-chain survey against the list of smelter and refiner facilities which have received an RMAP Conformant designation.
•Assessed each smelter according to red flag indicators defined in the OECD Framework, including: geographic proximity to the Covered Countries, known mineral source country of origin, RMAP audit status, credible evidence of unethical or conflict sourcing, and peer assessments conducted by credible third-party sources.
•Evaluated direct suppliers in the strength of their internal Conflict Minerals programs as reflected in their CMRTs based on four key criteria:
(1)Have you established a conflict minerals sourcing policy?
(2)Have you implemented due diligence measures for conflict-free sourcing?
(3)Do you review due diligence information received from your suppliers against your company’s expectations?
(4)Does your review process include corrective action management?
3. Design and Implement a Strategy to Respond to Identified Risks
•Provided direct suppliers with feedback on responses containing errors, inconsistencies or incomplete information and encouraged them to resubmit a valid response.
•Maintained an escalation plan in the event that we have to address non-responsive suppliers and/or to contact suppliers that provided incomplete or inaccurate supply chain information.
•Requested direct suppliers to remove specific smelters or refiners from their supply chain that we deemed to be high-risk.
4. Support Development and Implementation of Independent Third Party Audits
•Semtech does not have a direct relationship with conflict minerals smelters and refiners, nor do we perform direct audits of these entities. However, we rely upon third parties to coordinate and conduct third-party audits of these facilities. We rely upon the published results of these third-party audits like RMAP to validate the responsible sourcing practices of the smelters and other processing facilities in our supply chain.
5. Report Annually on Supply Chain Due Diligence
•In addition to this Report, further information about our supply chain due diligence is disclosed in the Semtech Policy Regarding Conflict Metals Procured from Conflict Areas and our Conflict Minerals Policy, which are posted on our website at https://www.semtech.com/quality/declarations.
•Reported supply chain smelter information in this Report.
Results of Due Diligence
For the reporting period January 1 to December 31, 2025, following our RCOI and our due diligence process, we have reason to believe that a portion of the conflict minerals used in our products originated from the Covered Countries, but we have not identified any instances in which the sourcing of conflict minerals directly or indirectly financed or benefitted armed groups in the Covered Countries.
As a result of Semtech’s due diligence efforts:
1.Received CMRT survey responses from 153 suppliers, representing 100% of our suppliers that we believe provide components to us, or engage in manufacturing activities for us, that may contain conflict minerals (the “Covered Components/Materials”).
2.Of the 153 responding suppliers, 90% indicated that the products they supply to Semtech do, in fact, constitute Covered Components/Materials.
3.Sixty-six of the responding suppliers represented that the conflict minerals contained in the Covered Components/Materials they supplied to Semtech either:
(a) did not originate, or are not believed to have originated, from the Covered Countries, or
(b) originated exclusively from recycled or scrap sources.
4.The remaining 87 responding suppliers represented that the Covered Components/Materials they provided to Semtech may contain conflict minerals that originated or may have originated from the Covered Countries, and that such conflict minerals did not originate exclusively from recycled or scrap sources. Each of these suppliers provided smelter and refinery information as part of their CMRT response.
5.Based on our review, Semtech has determined that 81% (221 of the 274) unique smelters and refineries identified by our responding suppliers as potentially present in our supply chain have been designated as RMAP Conformant by the Responsible Minerals Initiative, indicating that their sourcing practices have been validated through an independent third-party audit.
Risk Mitigation Measures
Semtech is taking or intends to continue to take the following steps to improve its due diligence during the next compliance period to further mitigate the risk that its necessary conflict minerals do not benefit armed groups in the Covered Countries:
•Increase the emphasis on clean and validated smelter and refiner information from our supply chain as the list of conflict-free smelters and refiners grows and more smelters and refiners declare their intent to enroll in the program.
•Encourage our direct suppliers to have due diligence procedures in place for their supply chains to improve the content of the responses from such direct suppliers and follow up with direct suppliers that appear to have gaps in their internal processes for conflict minerals.
•Engage with our direct suppliers more closely and provide direct suppliers with more information and training resources regarding responsible sourcing of 3TG.
•Request direct suppliers to remove specific smelters or refiners from their supply chain that we deem to be high-risk.
•Engage any direct suppliers that we have reason to believe are supplying Semtech with 3TG from sources that may be considered red flag sources and encourage them to establish alternative sources of 3TG.
•Encourage our direct suppliers to take these same steps with regard to their suppliers in our supply chain.
•Engage direct suppliers to encourage smelters or refiners in our supply chain, not yet certified by the RMAP or an equivalent independent third-party audit, to undergo smelter audits and verify compliance.
Additional Cautionary Statements
Semtech’s RCOI and due diligence measures are designed to address the inherent limitations of collecting conflict minerals origin and chain-of-custody information as a downstream purchaser operating within a complex, multi-tier international electronics supply chain. Because Semtech does not have a direct contractual relationship with, or operational control over, the smelters and refiners identified by its suppliers, Semtech necessarily relies on the accuracy and completeness of the information provided by its direct suppliers regarding the processing facilities in their supply chains. Semtech cannot independently verify all such information, and material misrepresentations or fraudulent disclosures by third parties may not be detectable even through robust due diligence processes.
Notwithstanding these limitations, Semtech believes that the determinations made in this Report represent a reasonable assessment of the current status of its conflict minerals compliance program, and such limitations do not diminish Semtech’s commitment to responsible sourcing or its ongoing efforts to advance a conflict-free supply chain as industry infrastructure, audit programs, and traceability tools continue to mature.
With respect to the scope of information reported, Semtech requested conflict minerals data from its direct suppliers at the product level. However, a number of suppliers responded at the company or business division level rather than at the individual product level, and were therefore unable to identify with specificity the smelters or refiners associated with components supplied to Semtech. As a result, certain smelters and refiners identified in this Report may not be confirmed as present in Semtech’s supply chain. Semtech continues to engage directly with suppliers that have provided company-level responses to improve the granularity and product-level specificity of future CMRT submissions.
