**Silicon Laboratories Inc.**

**Conflict Minerals Report**

**Calendar Year Ended December 31, 2025**

This Conflict Minerals Report of Silicon Laboratories Inc. ("Silicon Laboratories" or "the Company") has been prepared to comply with Rule 13p-1 under the Securities Exchange Act of 1934, as amended (the "Rule"). The Rule requires registrants to disclose information regarding the use and origin of conflict minerals necessary for the functionality or production of products manufactured or contracted to be manufactured by such registrants. The Rule defines "conflict minerals" as cassiterite, columbite-tantalite, gold, wolframite and their derivatives, which are limited to tin, tantalum, tungsten and gold. The purpose of the Rule is to identify whether a registrant's use of conflict minerals may have directly or indirectly financed or benefitted armed groups in the Democratic Republic of the Congo ("DRC") or an adjoining country (collectively, "Covered Countries").

For products which contain necessary conflict minerals, a registrant must conduct in good faith a reasonable country of origin inquiry ("RCOI") designed to determine whether any of the conflict minerals originated in the Covered Countries. If, based on such inquiry, the registrant knows or has reason to believe that any of the necessary conflict minerals contained in its products originated or may have originated in a Covered Country and knows or has reason to believe that those necessary conflict minerals may not be from recycled or scrap sources, the registrant must conduct due diligence on the source and chain of custody of those conflict minerals.

Certain of the Company's products contain conflict minerals, including gold, tantalum, tin and/or tungsten. These minerals are necessary to the functionality of the products contracted by the Company to be manufactured. Pursuant to the Rule, the Company undertook due diligence measures on the source and chain of custody of the conflict minerals in its products that the Company had reason to believe may have originated from the Covered Countries and may not have come from recycled or scrap sources.

The following describes: (a) the design of the Company's Conflict Minerals Program; (b) the Company's conclusion based on its RCOI; (c) the measures the Company has taken to exercise due diligence on the source and chain of custody of the conflict minerals contained in its products; and (d) the Company's products, including information on the facilities used to process the necessary conflict minerals in those products, the country of origin of the necessary conflict minerals in those products and the Company's efforts to determine the mine or location of origin of those conflict minerals with the greatest possible specificity.

**<u>Part 1 – Due Diligence</u>**

**Design of Conflict Minerals Program**

The design of the Company's conflict minerals program is in conformity 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 and related Supplements on Tin, Tantalum and Tungsten and on Gold (collectively, "OECD Guidance"), as it relates to the Company's position in the minerals supply chain. Summarized below are the design components of the Company's conflict minerals program as they relate to the five-step framework set forth in the OECD Guidance:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**1.Establish strong company management systems.**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Adopt and commit to a supply chain policy for minerals originating from conflict-affected and high-risk areas.

-The Company's supply chain policy requires all suppliers to maintain a conflict-free sourcing policy and to comply with the Company's internal policy based on the OECD Guidance.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Structure internal management systems to support supply chain due diligence.

-Vendors that supply the Company with products containing conflict minerals are required to complete a Responsible Minerals Initiative ("RMI") Conflict Minerals Reporting Template ("CMRT"), a supply chain survey designed to identify the smelters, refiners and countries of origin of the conflict minerals in products the vendors supply to a customer.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Establish a system of controls and transparency over the mineral supply chain.

-The Company maintains a dedicated internal system to track, analyze and approve supplier responses to supply chain surveys. The Company maintains records relating to its conflict minerals program in accordance with its record retention guidelines.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Strengthen Company engagement with suppliers.

-The Company has created an internal system of controls to ensure that both current and new suppliers report information regarding their supply chain.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Establish a Company level grievance mechanism.

-The Company maintains an external reporting system for individuals to report concerns of actions (including compliance with the Company's conflict minerals program) that may not comply with the Company's standards, contractual, regulatory or legal requirements.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**2.Identify and assess risks in the Company's supply chain.**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Identify risks in the supply chain as recommended in the OECD Guidance Supplements.

-The Company reviews the components of the products provided by its suppliers to determine if such products may contain conflict minerals.

-The Company requests suppliers that provide products which may contain conflict minerals to complete the CMRT survey. The Company contacts vendors that do not respond to the supply chain survey by a specified date, requesting their responses. If necessary, the Company escalates its requests to management or other appropriate personnel as described in its supply chain policy.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Assess risks of adverse impacts in light of the standards of the Company's supply chain policy consistent with the due diligence recommendations in the OECD Guidance.

-The Company reviews completed CMRT surveys for compliance with the Company's internal policy based on the OECD Guidance.

-The Company compares the smelters and refiners identified by the CMRT surveys against the list of facilities that have received a "conformant" designation from the RMI's Responsible Minerals Assurance Process ("RMAP").

-The Company assesses whether the smelters and refiners have carried out all elements of reasonable due diligence for responsible supply chains of minerals from conflict-affected and high-risk areas.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**3.Design and implement a strategy to respond to identified risks.** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Devise and adopt a risk management plan.

-The Company has adopted a risk management plan, which includes measures for risk mitigation for suppliers using smelters and refiners that have not received a conformant designation from the RMAP.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Implement the risk management plan, monitor and track performance of risk mitigation efforts and report back to designated senior management.

-The Company's risk mitigation efforts for smelters and refiners that have not received a conformant designation from the RMAP include: (a) reviewing the mine location; (b) requesting and reviewing Certificate of Origin documents from the supplier; (c) requesting an action plan from the supplier; and (d) performing a risk assessment with an internal management team for further consideration of risk mitigation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Undertake additional fact and risk assessments for risks requiring mitigation, or after a change of circumstances.

-The Company's conflict minerals policy includes an on-going program for both current and new suppliers. Any change in the Company's supply chain may require that certain steps be repeated in order to prevent or mitigate adverse impacts.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Report findings of the supply chain risk assessment to the designated senior management of the Company.

-The Company reports findings from its supply chain risk assessment to its Executive Quality Council, which consists of members of the Company's executive management.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• If and when required by the Rule, obtain an independent private sector audit of the Company's Conflict Minerals Report.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**4.Carry out independent third-party audit of supply chain due diligence at identified points in the supply chain.**

-The Company supports development and implementation of due diligence practices and tools, including:

oThe CMRT survey completed by the Company's suppliers,

oThe RMAP assessment process used by the Company to determine facilities that have received a conformant designation.

-The Company encourages all of its conflict mineral suppliers to use facilities that have received a conformant designation.

-The Company requests its suppliers to remove sanctioned smelters and refiners from their supply chain to ensure compliance with U.S. sanctions and the OECD Due Diligence Framework.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**5.Report on supply chain due diligence.**

**Conclusion Based on Reasonable Country of Origin Inquiry**

Step 2 of the Company's Conflict Minerals Program, *Identify and assess risks in the Company's supply chain*, represents its RCOI. This step is designed to determine whether any of the conflict minerals in the Company's products originated in the Covered Countries. Based on the results of the Company's RCOI, the following was determined:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• A portion of the necessary conflict minerals contained in the Company's products originated or may have originated in the Covered Countries and those necessary conflict minerals may not be solely from recycled or scrap sources. The Company performed due diligence measures on these conflict minerals.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• A portion of the necessary conflict minerals contained in the Company's products are from recycled or scrap sources. Conflict minerals obtained from recycled or scrap sources are considered DRC conflict free pursuant to Rule 13p-1.

**Description of Due Diligence Measures Performed**

Steps 3 and 4 of the Company's Conflict Minerals Program, *Design and implement a strategy to respond to identified risks* and *Carry out independent third-party audit of supply chain due diligence at identified points in the supply chain,* respectively, represent the due diligence measures performed by the Company. The purpose of these measures is to determine whether the necessary conflict minerals contained in the Company's products did or did not directly or indirectly finance or benefit armed groups in the Covered Countries in order to conclude whether such products were DRC conflict free.

Below is a description of the measures the Company performed to exercise due diligence on the source and chain of custody of the necessary conflict minerals contained in its products:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Adopted a risk management plan, which included measures for risk mitigation for suppliers using smelters and refiners that have not received an RMAP conformant designation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Requested the Company's existing and new conflict mineral suppliers to use facilities that have received a conformant designation. Suppliers that use facilities without such designation may be removed as an approved vendor.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Monitored and tracked suppliers to ensure compliance with the Company's Conflict Minerals Policy.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Performed risk mitigation efforts with suppliers identified not to be in conformity with the Conflict Minerals Policy by working with them to bring them into compliance.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Reported findings from the Company's supply chain risk assessment to its Executive Quality Council.

**Results of Due Diligence Measures and Product Determination**

The Company received responses from all of its direct suppliers subject to the supply chain survey for 2025. Collectively, their responses listed 235 smelters and refiners within their supply chains. The tables below list the smelters and refiners of conflict minerals that may have been used to process the necessary conflict minerals in the Company's products in 2025. Efforts to determine this population are described above under the caption *Description of Due Diligence Measures Performed*. The information presented is derived from information provided by the Company's direct suppliers and the RMAP.

**Inherent Limitations on Due Diligence Measures**

Silicon Laboratories is a downstream company in the conflict minerals supply chain, and as such, its due diligence efforts can provide only reasonable, not absolute, assurance regarding the source and chain of custody for the necessary conflict minerals in its products. The Company has no direct relationships with smelters and refiners, and its due diligence processes are based on the necessity of seeking data from its direct suppliers, who in turn seek similar information within their supply chains. Additionally, the complete supply chain from the smelters and refiners to the Company's final products involves a complex multi-step process that may be subject to changes without the Company's knowledge.

**Independent Private Sector Audit** 

An independent private sector audit is not required for 2025.

**Future Due Diligence Measures**

For the next reporting period, the Company is continuing to engage in the activities described above in *Design of Conflict Minerals Program* to mitigate the risk that its necessary conflict minerals benefit armed groups. The Company will continue to contact suppliers that use smelters and refiners identified in its supply chain survey process that have not received a conformant designation and request their participation in the RMAP or other independent third party audit program in order for them to obtain such a conformant designation.

**<u>Part 2 – Product Description</u>**

**Description of the Company's products**

Silicon Laboratories is a leader in secure, intelligent wireless technology for a more connected world. The Company's integrated hardware and software platform, intuitive development tools, industry leading ecosystem and robust support enable customers in building advanced industrial, commercial, home and life applications. The Company's semiconductor devices leverage standard complementary metal oxide semiconductor (CMOS), a low cost, widely available process technology.

As a fabless semiconductor company, the Company relies on third-party semiconductor fabricators to manufacture the silicon wafers that reflect its integrated circuit ("IC") designs. Each wafer contains numerous die, which are cut from the wafer to create a chip for an IC. The Company relies on third parties to assemble, package, and, in most cases, test these devices and ship these units to its customers.

**The following facilities, to the extent known, may have been used to process the necessary conflict minerals in the Company's products:** <sup>(1)</sup>
