## Exhibit 1.01

**Exhibit 1.01**

**Conflict Minerals Report**

**of Monolithic Power Systems, Inc.**

**for the Year Ended December 31, 2025**

This Conflict Minerals Report of Monolithic Power Systems, Inc. (including its consolidated subsidiaries, "MPS," "we," "us," "our") is being filed for the reporting period from January 1, 2025 to December 31, 2025 in compliance with Rule 13p-1 of the Securities Exchange Act of 1934, as amended ("Rule 13p-1").

Rule 13p-1, through Form SD, requires the disclosure of certain information if a company manufactures or contracts to manufacture products for which certain "conflict minerals" (as defined below) are necessary to the functionality or production of such products. Form SD defines "conflict minerals" as: (i)(a) columbite-tantalite, (b) cassiterite, (c) gold and (d) wolframite, or their derivatives, which are currently limited to tantalum, tin and tungsten; or (ii) any other mineral or its derivatives determined by the U.S. Secretary of State to be financing conflict in the Democratic Republic of the Congo or an "adjoining country," as such term is defined in Form SD (collectively, the "Covered Countries").

Because conflict minerals were necessary to the functionality or production of products contracted by us manufactured between January 1, 2025 and December 31, 2025 (the "Reporting Period"), we were required to conduct in good faith a reasonable country of origin inquiry ("RCOI"). Based on the RCOI, if we have reason to believe our necessary conflict minerals may have originated in the Covered Countries and have reason to believe that they may not be from recycled or scrap sources, we must exercise due diligence on the source and chain of custody of our conflict minerals, and file a Conflict Minerals Report to describe our due diligence efforts on the source and chain of custody of such conflict minerals.

**Forward-Looking Statements**

**1.1 *Company Overview***

MPS is a fabless global company that provides high-performance, semiconductor-based power electronics solutions. Incorporated in 1997, our three core strengths include deep system-level knowledge, strong semiconductor design expertise, and innovative proprietary technologies in the areas of semiconductor processes, system integration, and packaging. These combined advantages enable us to deliver reliable, compact, and monolithic solutions found in storage and computing, enterprise data, automotive, industrial, communications and consumer applications. Our mission is to reduce energy and material consumption to improve all aspects of quality of life and create a sustainable future. We believe that we differentiate ourselves by offering solutions that are more highly integrated, smaller in size, more energy-efficient, more accurate and more reliable with respect to performance specifications and, consequently, more cost-effective than many competing solutions. We plan to continue to introduce new products within our existing product families, as well as new, innovative products that expand our market.

------

**1.2. *Products Overview***

Our proprietary process and packaging technologies enable us to design and deliver smaller, single-chip power management solutions. These technologies simplify the design process and are applicable across a wide range of analog applications within the storage and computing, enterprise data, automotive, communications, consumer, and industrial end markets.

Our key product families include, but are not limited to, the Direct Current ("DC") to DC, Alternating Current ("AC") to DC, driver metal-oxide-semiconductor field-effect transistor, power management IC, current limit switch and lighting control products.

Our product families are differentiated from those of our competitors with respect to their high degree of integration and strong levels of accuracy, power efficiency, quality and longevity, making them cost-effective and more sustainable relative to many competing solutions. For example, DC to DC solutions are used to convert and control voltages within a broad range of electronic systems, such as cloud-based and on-premises CPU servers and workstations, AI systems, memory, storage solutions, notebooks, infotainment, power sources, home appliances, network infrastructure and satellite communications. We believe our DC to DC products are differentiated in the market, particularly with respect to their high degree of integration, high voltage operation, high load current, high switching speed, small footprint, and high energy efficiency. These features are important to our customers as they are designed to result in fewer components that need to be produced and consumed, a smaller form factor, more accurate regulation of voltages, lower power consumption and, ultimately, lower system cost, increased reliability and lower carbon emissions through the elimination of many discrete components and power devices.

**2. *Conflict Minerals Policy***

MPS has adopted a Conflict Minerals Policy, which is publicly available at https://www.monolithicpower.com/en/about-mps/policies-and-documents.html. As a key component of our conflict minerals program, this policy:

● Reflects MPS's support and contribution to industry-wide efforts to validate that the conflict minerals used in its products come from socially responsible sources.

● Reflects MPS's actions to conduct upstream supply chain due diligence of minerals for conflict-affected and high-risk areas in all material respects with the guidance issued by the Organization for Economic Cooperation and Development ("OECD").

● Is communicated to MPS's supply chain with the expectation of compliance with the policy, which requires our suppliers to provide sourcing information using the Conflict Minerals Reporting Template ("CMRT") developed by the Responsible Minerals Initiative ("RMI").

The contents of any website referenced in this Conflict Minerals Report are not a part of this Conflict Minerals Report.

**3. *RCOI and RCOI Conclusion***

MPS has conducted the RCOI in good faith regarding the conflict minerals included in its products during the Reporting Period to determine whether any such conflict minerals originated in the Covered Countries and/or whether any of the conflict minerals were from recycled or scrap sources. The results of MPS's RCOI regarding conflict minerals are included below.

MPS's global supply chain is complex. As a fabless company in the analog semiconductor business, MPS does not manufacture its products or engage in the actual mining of conflict minerals. In addition, MPS does not make purchases of raw ore or unrefined conflict minerals. In the course of its business operations, however, MPS contracts with subcontractors to manufacture its products with minerals, and those manufacturers may source conflict minerals to manufacture our products. Because MPS does not purchase conflict minerals directly from mines, smelters or refiners, our manufacturers and other third parties in our supply chain create a potential link between MPS and the original sources of conflict minerals. As a result, MPS relies on its subcontractors to provide information regarding the origin of any conflict minerals that are included in its products, and to ensure that all conflict minerals sourced for our products are conformant under the RMI standards.

MPS evaluated whether conflict minerals were used in its products, and as a result of this process, MPS identified those key subcontractors that it believed could potentially provide materials or components containing conflict minerals (collectively, the "Covered Suppliers"). MPS then utilized the CMRT to collect sourcing information from the Covered Suppliers in order to identify whether: (i) conflict minerals sourced by such Covered Suppliers originated in Covered Countries; and (ii) smelters and refiners (collectively, "smelters") in our supply chain have been validated as conformant in accordance with the Responsible Minerals Assurance Process ("RMAP") developed by the RMI. Such responses from the Covered Suppliers were reviewed by MPS's Quality Assurance group. An escalation process was initiated with Covered Suppliers who were non-responsive after the above contacts were made, or with Covered Suppliers whose initial (or subsequent) response was not complete or otherwise warranted clarification or confirmation.

After review by MPS's Quality Assurance group, non-conformant smelters were identified and removed throughout 2025. The result of this process is that no "non-conformant" or "not eligible" smelters were included in MPS's CMRT reporting. All gold, tantalum, tungsten and tin smelters were reported to be 100% RMAP conformant.

------

**4.1 *Due Diligence Program Design***

Our conflict minerals due diligence program is designed to conform in all material respects with the framework recommended by the OECD Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas (the "OECD Guidance"), as it relates to our supply chain position as a "downstream" purchaser. Summarized below are the components of our program as they relate to the five-step framework set forth in the OECD Guidance:

Step 1: Establish strong company management systems

● Adopted and publicly communicated a Code of Social Responsibility, in which we uphold the Code of Conduct of the Responsible Business Alliance ("RBA"), which includes the standards regarding responsible sourcing of conflict minerals. In addition, as a member of the RBA, we require that our Covered Suppliers acknowledge and implement the RBA's Code of Conduct, which includes an obligation to conduct due diligence on the source and chain of custody of conflict minerals. Both the Code of Social Responsibility and the Supplier Code of Conduct can be found at https://www.monolithicpower.com/en/about-mps/policies-and-documents.html.

● Adopted and publicly communicated a Conflict Minerals Policy, which is posted on our website at https://www.monolithicpower.com/about-mps/policies-and-documents.html.

● Assembled an internal conflict minerals team, with representation by our Operations, Legal and Compliance, Sales, Procurement, Quality Assurance, Supply Chain Management and Environmental, Social and Governance ("ESG") departments.

● Established a system of control and transparency over our conflict minerals supply chain by engaging our Covered Suppliers and requesting their completed CMRT. This process was further strengthened in 2025 as MPS engaged a third-party compliance vendor to oversee and manage this step.

● Maintain an independent corporate hotline to allow any employees and third-party business partners to file a complaint confidentially and anonymously about any matter of concern, including those related to conflict minerals (unless prohibited by local privacy laws for employees located in the European Union). The details for the hotline are available in our Conflict Minerals Policy posted on our website https://www.monolithicpower.com/about-mps/policies-and-documents.html.

Step 2: Identify and assess risk in the supply chain

● Identify our Covered Suppliers based on the type of services they provide.

● Perform the following processes by MPS's Quality Assurance group and the third-party compliance vendor:

● Review Covered Suppliers' responses for completeness and accuracy.

● Compare information in Covered Suppliers' responses with the list of the conflict minerals processing facilities that receive a "conformant" designation, produced by the RMAP. The RMI developed an overarching RMI Recognition Process that covers requirements for program cross-recognition of industry initiatives' comparable assessment programs, as well as other types of recognition including Upstream Assurance Mechanisms and Voluntary Standard Systems recognition.

● Contact non-responsive Covered Suppliers and request their responses.

● Provide Covered Suppliers with feedback on responses containing errors, inconsistencies, or incomplete information.

● Require potential new suppliers to complete a CMRT for diligence review.

Step 3: Design and implement a strategy to respond to identified risks

● Report progress on a regular basis to the management team, and our Board and its committees.

● Identify main risks in our supply chain.

● Require that Covered Suppliers remove specific smelters from their supply chain that are not conformant or fail to comply with our Conflict Minerals Policy.

● Inform non-responsive suppliers that we will assess, and potentially withhold, future business with them if they do not acquire materials from conflict-free sources within the Covered Countries and do not provide their supply chain conflict minerals information to us using the CMRT.

● Conduct outreach with customers, respond to their concerns and comply with their requests regarding our supply chain.

------

Step 4: Carry out independent third-party audit of supply chain due diligence at identified points in the supply chain

● Rely on the RMAP to coordinate third-party audits of smelters to validate the sourcing practices of such facilities in our supply chain.

● Provide indirect financial support for such third-party audits through our continuing memberships with the RBA and RMI.

Step 5: Report on supply chain due diligence

● Publish conflict minerals information in our annual Corporate Social Responsibility Report, which is available at https://www.monolithicpower.com/media/mps_cms_document/e/s/esg-2026.pdf.

● File our Form SD annually, including this Conflict Minerals Report, with the SEC and make it available on our website at https://www.monolithicpower.com/about-mps/policies-and-documents.html.

● Conduct engagements with our key stakeholders, including stockholders, analysts, customers and rating agencies, and discuss our due diligence and compliance efforts related to conflict minerals and our supply chain.

● Report supply chain smelter information in this Conflict Minerals Report.

**4.2 *Description of Due Diligence Measures Performed***

Below is a description of the measures we performed for this Reporting Period to exercise due diligence on the source and chain of custody of our necessary conflict minerals.

We requested supply chain information from 100% of our Covered Suppliers that may use necessary conflict minerals in our products and components to determine whether any of these minerals originated in the Covered Countries or were from recycled or scrap sources. We tracked these communications with Covered Suppliers, aggregated CMRT responses for analysis and reporting, and performed additional follow-ups with those suppliers whose CMRT responses contained incomplete or potentially inaccurate information.

Based on the due diligence described above, as of December 31, 2025, we determined that all of our Covered Suppliers that may have potentially sourced conflict minerals did so from processing facilities validated by the RMAP as conformant, or removed non-compliant facilities from their supply chain.

Attached hereto as Exhibit A is the list of smelters used within our supply chain that, based on our due diligence process detailed above, we believe are conformant as determined by the RMAP.

**4.3 *Steps Taken or to be Taken to Mitigate Risk and Improve Due Diligence***

We maintain an ongoing effort to mitigate the risk that armed groups in conflict-affected and high-risk areas could benefit from our use of conflict minerals. We continue to encourage our Covered Suppliers to train their smelters and to recommend that their smelters participate in an independent assessment through RMAP.

**4.4 *Inherent Limitations on Due Diligence Measures***

Because of our fabless manufacturing strategy and our contract manufacturing process for our branded products, our due diligence measures provide reasonable, not absolute, assurance regarding the source and chain of custody of the necessary conflict minerals in the products we contract to have manufactured. Given our place in the supply chain, we have no direct relationships with smelters and therefore possess no independent means of determining the source and origin of conflict mineral ores processed by smelters. Our due diligence processes require that we seek data from our Covered Suppliers to identify the original sources of the necessary conflict minerals. We also rely, to a large extent, on information collected and provided by independent third-party audit programs. Such sources of information may yield inaccurate or incomplete information and may be subject to fraud.
