## Exhibit 1.01

**Exhibit 1.01** 

**Rambus Inc.** 

**Conflict Minerals Report** 

**For the Reporting Period from January 1, 2025 to December 31, 2025** 

**Introduction** 

This Conflict Minerals Report (this "Report") of Rambus Inc. ("we," "our," "us," "Rambus" or the "Company") for the reporting period January 1, 2025 to December 31, 2025 (the "Reporting Period") has been prepared in accordance with the requirements of Rule 13p-1 (the "Rule") and Form SD promulgated under the Securities Exchange Act of 1934, as amended.

The Rule requires disclosure of certain information when a company manufactures or contracts to manufacture products where the minerals specified in the Rule are necessary to the functionality or production of those products. The specified minerals are referred to as "Conflict Minerals," which include gold, columbite-tantalite (coltan), cassiterite, wolframite and their derivatives, which are limited to tantalum, tin and tungsten. The "Covered Countries" for purposes of the Rule and this Report are the Democratic Republic of Congo (the "DRC"), or any adjoining country, including the Republic of Congo, the Central African Republic, South Sudan, Uganda, Rwanda, Burundi, Tanzania, Zambia and Angola.

This Report and Form SD can be found on our website at www.rambus.com.

**Company Overview** 

Rambus delivers industry-leading chips and silicon IP for the data center and AI infrastructure. With over three decades of advanced semiconductor experience, our products and technologies address the critical bottlenecks between memory and processing to accelerate data-intensive workloads. By enabling greater bandwidth, efficiency and security across next-generation computing platforms, we make data faster and safer.

During the Reporting Period we continued to ship our physical semiconductor products, including DDR4 and DDR5 memory interface chipsets for memory modules utilized in cloud data center and enterprise servers, and client computing systems. For such products we operate a fabless business model and use third-party foundries, assembly and test manufacturing contractors to manufacture, assemble, test and provide our semiconductor products.

**Description of the Company's Conflict Minerals Policy** 

Our goal is to eliminate the use of Conflict Minerals. We are aware that our physical semiconductor products contain tin, tantalum, tungsten and gold ("3TG") metals that are necessary to the functionality or production of those products. To this end, we work with our applicable suppliers to identify the sources of all 3TG metals used in our physical semiconductor products. If any of these metals originate from the Covered Countries, then further investigation is required.

We use the tools provided by the Responsible Minerals Initiative ("RMI") to gather information from our suppliers. The information requested includes the name and location of smelters or refiners used to produce the metals, and the origin of the minerals. Our due diligence process and efforts are consistent with 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 ("OECD Guidance").

Our Conflict Minerals Policy can be found on our website at www.rambus.com.

------

**Description of the Company's Supply Chain** 

Because we operate a fabless business model, we do not directly purchase 3TG from mines, smelters, or refiners. Therefore, we must rely on our suppliers to provide information regarding the country of origin of Conflict Minerals that are included in the Covered Products (as defined below). Many of our suppliers do not purchase raw materials directly and must rely on their downstream suppliers and sub-suppliers to determine the origin of their raw materials. Thus, reliably determining the origin is a difficult task, and our suppliers are highly dependent on the information provided to them by their suppliers and sub-suppliers which are often far removed from the direct smelter or refiner. Additionally, many of our suppliers are not directly subject to the same conflict minerals law and regulations as we are.

**Identification of Conflict Minerals and of the Company's Products Covered by this Report** 

We sent a questionnaire to our operating business units inquiring whether during the Reporting Period any of our units manufactured or contracted to manufacture any products containing Conflict Minerals necessary to such products' functionality or production.

Based on these inquiries, we determined that our chipsets were the only products that met this test ("Covered Products"). We found that Conflict Minerals were not necessary to the functionality or production of any product that we manufactured or contracted to manufacture other than the Covered Products that we contracted to manufacture during the Reporting Period.

From this information, we developed a list of direct suppliers within our applicable supply chain to be surveyed and who provided 3TG materials for our products. Engineering and evaluation materials were not included in our analysis.

**Description of the Company's Reasonable Country of Origin Inquiry** 

We conducted in good faith a reasonable country of origin inquiry ("RCOI") with respect to the Covered Products that were manufactured or contracted to be manufactured by us during the Reporting Period. The RCOI is reasonably designed to determine if any of the Conflict Minerals in the Covered Products originated in the Covered Countries and whether any of the Conflict Minerals may be from recycled or scrap sources.

Once we identified our list of suppliers, we began the process of surveying the supply chain using the RMI's Conflict Minerals Reporting Template ("CMRT"). The CMRT is used predominantly throughout the electronics industry and requests relevant information, including details of the smelters and refiners where the materials were processed and the location of mines where the minerals originated.

We informed each identified supplier of our desire to use only materials verified to be conflict-free and asked them to return a completed CMRT. Responses were reviewed for completeness, reasonableness, and consistency, and we followed up with our suppliers for corrections and clarifications as needed.

Based on the responses from the suppliers, we were not able to conclusively determine the complete geographic origin of all 3TG materials used in our Covered Products. Therefore, we proceeded to perform the due diligence process outlined below.

**Description of the Company's Due Diligence Process** 

Based on the information provided to us by our suppliers, we undertook additional due diligence processes and efforts based on the OECD Guidance in order to determine if any Conflict Materials included in our Covered Products may have originated in the Covered Countries and if so, whether they benefited armed groups in those countries.

In accordance with the OECD Guidance, the design of our due diligence includes the five steps described below.

------

***Step 1: Establish Strong Company Management Systems***

We have completed a number of steps to establish a management system for addressing the sourcing of Conflict Minerals in our Covered Products. These actions include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Adopt and Commit to a Supply Chain Policy for Conflict Minerals:** We are committed to responsible
relationships with customers, suppliers and business partners under our Code of Business Conduct and Ethics ("Code of Conduct") publicly available on our website at www.rambus.com. Our Code of Conduct standards apply worldwide and
outline expected behaviors for everyone who works for us or serves on our Board of Directors. These expected behaviors include, without limitation, conducting all business relationships, including with suppliers, in an honest and ethical manner and
in compliance with all applicable laws and refraining from participating or aiding a supplier who is seeking to commit an unethical act. We have also adopted a Conflict Minerals Policy.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Internal Management to Support Supply Chain Due Diligence:** We have established a management system for
disclosing our use of Conflict Minerals under the Rule. This management system is sponsored by our General Counsel as well as executive-level representatives and a team of subject matter experts from relevant functions such as finance, legal,
operations and engineering. The team of subject matter experts is responsible for ensuring our Conflict Minerals disclosure compliance.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Controls and Transparency to Support Supply Chain Diligence:** As described above, we undertook an RCOI with
respect to the Conflict Minerals in our supply chain by requesting a CMRT be completed by each of our suppliers to gather information about their use of Conflict Minerals, the smelters and refiners in their supply chain that are included in our
Covered Products, and the countries of origin for such Conflict Minerals.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Supplier Engagement:** With respect to the OECD requirement to strengthen engagement with suppliers, we
inform our suppliers of our conflict mineral efforts and that they are expected to investigate their supply chains for conflict minerals information and inform us of the results.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Grievance Mechanism:** Code of Conduct contains procedures whereby employees can report violations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Maintain records:** We have an existing document retention policy that includes retaining Conflict Minerals
due diligence documentation.

***Step 2: Identify and Assess Risk in the Supply Chain***

As a fabless producer of semiconductor products, we have no direct relationship with 3TG suppliers. Thus, we rely on our direct suppliers to provide us with the necessary information about the source of Conflict Minerals contained in the Covered Products that we contract with them to manufacture for us. Our suppliers are similarly reliant upon information provided by their suppliers to provide information regarding the country of origin of Conflict Minerals that are included in the Covered Products. Thus, there is a risk that the final information provided to us and upon which we rely is incomplete or inaccurate.

***Step 3: Carry Out Independent Third-Party Audit of Supply Chain Due Diligence at Identified Points in the Supply Chain***

Because we do not have direct relationships with suppliers of the 3TG materials, we rely upon third parties to perform audits and certify smelters/refiners as conflict-free. Responsible Minerals Assurance Process (RMAP) coordinates audits of 3TG smelters/refiners and publishes lists of those that are found to be conflict-free by following OECD Guidelines. The RMI also publishes names of smelters/refiners that are actively in the process of becoming certified conflict-free, but have not completed the process to date. We use these published lists to determine if the smelters and refiners supplying 3TG materials for our Covered Products are conflict-free. If the sources of all 3TG materials for a product have been identified as conflict-free, then we likewise consider such product as conflict-free.

------

***Step 4: Report on Supply Chain Due Diligence***

We report on our due diligence efforts as required by law. We publicly filed the Form SD and this Report with the SEC.

This Report includes information about the RCOI we undertook, our due diligence process designed to conform with the OECD Guidelines, the list of known smelters and refiners utilized in our supply chain identified in our due diligence process, and a description of our products that incorporate Conflict Minerals necessary to the functionality or production of such products.

**Findings and Conclusions** 

During the Reporting Period, we utilized six suppliers with respect to our physical semiconductor products and required all of these suppliers to perform and report on their supply chain due diligence through the use of the CMRT. We received a 100% response rate to our requests. Responses from our suppliers using the CMRT have been reviewed, combined and summarized. Responding parties provided a CMRT which includes a declaration page and a list of smelter and refinery names. Based on the information provided to us by our suppliers, we believe that, to the extent reasonably determinable, the facilities that were used to process the Conflict Minerals contained in the Covered Products included the smelters and refiners listed in Annex I below.

All responding suppliers provided complete lists of smelters representing 100% of the 3TG materials they utilized. All of suppliers declared that a portion of the 3TG metals came from the Covered Countries. However, these suppliers also indicated that such materials came from a smelter or refiner that has been audited and is listed as conflict-free and conformant by the RMI.

We combined the responses from all suppliers and prepared a list of unique smelter or refiner names. We then used the RMI conformance lists to determine if the Conflict Minerals originate from the Covered Countries and could be benefitting armed groups. All of the smelters/refiners on our list have been verified as conformant by the RMAP. Therefore, based on our due diligence efforts, we conclude the Conflict Minerals contained in our Covered Products come from suppliers using smelters or refiners listed as conformant by RMI. However, we rely on our direct suppliers to provide us with the necessary information about the source of Conflict Minerals contained in the Covered Products that we contract with them to manufacture for us and our suppliers are similarly reliant upon information provided by their suppliers. Thus, there is a risk that the final information provided to us and upon which we rely is incomplete or inaccurate.

**Future Steps to Improve Due Diligence** 

We have communicated our expectations to our contract manufacturers regarding our commitment to sourcing minerals for our products in a manner that does not finance or benefit armed groups in the Covered Countries. We plan to continue our inquiry method and utilize the CMRT to collect and report on due diligence activities with our supply base. We continue to work with our suppliers to improve the quality and completeness of information collected by using the most updated CMRT form. We will continue to review our supplier responses, provide feedback as necessary, encourage our suppliers to remain committed to conflict-free sources and engage with our relevant suppliers in order to build their knowledge and capacity so they are able to provide us with complete and accurate information on the source and chain of custody of Conflict Minerals in our supply chain.

**Conclusion** 

Based on our due diligence efforts and subject to the limitations of such efforts as detailed above, we conclude the Conflict Minerals contained in our Covered Products come from suppliers using smelters or refiners listed as conformant by RMI.

**Additional Risk Factors** 

The statements above are based on the RCOI process and due diligence performed in good faith by us. These statements are based on the infrastructure and information available at the time. A number of factors could introduce errors or otherwise affect our Conflict Minerals status. These factors include, but are not limited to, gaps in supplier data, gaps in smelter data, errors or omissions by suppliers, errors or omissions by smelters, smelter classifications, all instances of Conflict Minerals necessary to the functionality or manufacturing of our products possibly not yet having been identified, gaps in supplier education and knowledge, timeliness of data, public information not discovered during a reasonable search, errors in public data, language barriers and translation, supplier and smelter unfamiliarity with the protocol, oversights or errors in conflict free smelter audits, Covered Countries sourced materials being declared secondary materials, companies going out of business, certification programs being not equally advanced for all industry segments and metals, and smuggling of Conflict Minerals from the Covered Countries to countries beyond the Covered Countries.

**Forward-looking Statements** 

This Conflict Minerals Report contains forward-looking statements. These statements include statements regarding steps we intend to examine to further mitigate risk. We also use words such as "believe," "expect," "future," "intend" and similar expressions to identify forward-looking statements. All forward-looking statements involve risk and uncertainty. When considering these statements, you should also consider the important factors described in this Conflict Minerals Report under the heading "Additional Risk Factors" and in the reports and documents we file from time to time with the SEC, including the factors described under the sections titled "Risk Factors" in our most recently submitted Annual and Quarterly Reports on Forms 10-K and 10-Q, respectively. Except as required by law, we disclaim any obligation to update information contained in these forward-looking statements whether as a result of new information, future events, or otherwise.
