Exhibit 1.01

This unaudited Conflict Minerals Report (this “CMR”) of ON Semiconductor Corporation (the “Company,” “onsemi,” “we” or “us”) for the year ended December 31, 2024 is attached as Exhibit 1.01 to the Company’s Specialized Disclosure Report on Securities and Exchange Commission Form SD (the “Form SD”). This CMR is also publicly available on the Company’s website: https://www.onsemi.com/company/environmental-social-and-governance/social-responsibility (the “Social Responsibility Webpage”). The content of any website referred to in this CMR is included for general information only and is not incorporated by reference in this CMR.

Pursuant to Section 13(p) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and Rule 13p-1 thereunder, which implements Section 1502 of the Dodd-Frank Wall Street Reform and Consumer Protection Act (Section 13(p) of the Exchange Act, Rule 13p-1 thereunder and Section 1502 of the Dodd-Frank Wall Street Reform and Consumer Protection Act collectively, the “Conflict Minerals Regulations”), the Company is required to make certain inquiries and perform certain due diligence with respect to any “conflict minerals” (as defined in the Conflict Minerals Regulations) that are necessary for the functionality or production of a product manufactured (or contracted to be manufactured) by the Company or any of its subsidiaries.

onsemi is driving disruptive innovations to help build a better future. With a focus on automotive and industrial end-markets, the Company is accelerating change in megatrends such as vehicle electrification and safety, sustainable energy grids, industrial automation, and 5G and cloud infrastructure. With a highly differentiated and innovative product portfolio, onsemi creates intelligent power and sensing technologies that solve the world’s most complex challenges and leads the way in creating a safer, cleaner and smarter world.

As a purchaser of products containing the minerals tantalum, tin, tungsten or gold (collectively, “3TG”) from suppliers for use in our manufacturing process, the Company continues to be concerned about the reports of violence and human rights violations resulting from the sourcing of such minerals from the Democratic Republic of the Congo and adjoining countries (“Covered Countries”) and from conflict-affected and high-risk areas (“CAHRAs”). The Company’s annual Sustainability Report, which addresses these concerns and other actions the Company is taking in the area of social responsibility, is available on the Social Responsibility Webpage.

For purposes of this CMR, the term “products” is used to describe products manufactured (or contracted to be manufactured) by the Company or any of its subsidiaries. As a result, when conducting its conflict minerals analysis as required by the Conflict Minerals Regulations, the Company has considered its sole product to be semiconductor components.

This CMR describes the process undertaken for products that were manufactured, or contracted to be manufactured, during calendar year 2024 and that contain conflict minerals. This CMR is unaudited, as an independent private sector audit is not required pursuant to guidance provided by the Securities and Exchange Commission (the “SEC”).

As a result of its inquiry, the Company determined that conflict minerals are necessary to the functionality of the Company’s products. In particular, these minerals provide internal electrically conductive connections to the various circuit elements required to manufacture a working semiconductor device and/or provide an electrically conductive path to connect the semiconductor device to the electronic application in which it is utilized. When sourcing conflict minerals, however, the Company expects its suppliers to share our goals of social, environmental and ethical conduct and implement steps to create a responsible supply chain.

Conflict minerals are obtained from multiple sources worldwide, and the Company does not desire to eliminate those originating in Covered Countries and from CAHRAs. However, the Company is committed to pursuing conflict-free sourcing of minerals from our supply chain through collaboration with our suppliers, including through our activities as a member of the Responsible Business Alliance (the “RBA”) and a full member of the Responsible Minerals Initiative (the “RMI”), which began as a joint effort between the RBA and the Global e-Sustainability Initiative. As a member of the RMI, we are required to engage in reasonable due diligence with respect to our supply chain to ensure such minerals are not being sourced from entities supporting armed conflict within the Covered Countries or CAHRAs. The Company also recognizes the importance of supporting responsible mineral sourcing from the Covered Countries or CAHRAs so as not to have a negative impact on the economies of those countries.

Due Diligence

In accordance with the Conflict Minerals Regulations, the Company conducted a reasonable country of origin inquiry (“RCOI”) designed to determine whether any of the conflict minerals in its products originated in a Covered Country or are from recycled or scrap sources. Based on its RCOI, the Company was unable to reasonably conclude that all its conflict minerals did not originate in a Covered Country or come from recycled or scrap sources, and the Company continues its due diligence on the source and chain of custody of its conflict minerals. In connection with this supply chain due diligence, the Company, in accordance 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 (Third Edition, OECD 2016) and the related Supplements on 3TG (collectively, the “OECD Guidance”), executed the following steps:

• OECD Guidance Step 1: Establish a strong company management system

• The Company adopted and continually reviews and updates its responsible minerals sourcing policy, as appropriate, to reflect the procedures by which the Company and its 3TG suppliers should conduct due diligence related to conflict minerals. The Corporate Responsible Minerals Team reviews any changes to the policy or governing documents. This policy is made publicly available on the Social Responsibility Webpage.

• The Company maintains an internal management team to support the supply chain due diligence, and has instituted a systematic process. This team includes employees within the Company’s supplier quality, external manufacturing operations, global sourcing and procurement, and legal departments. Additionally, the Audit Committee of the Board of Directors of the Company reviews the Responsible Minerals Compliance Program quarterly to track the progress towards the program’s goals.

• The Company utilizes the conflict minerals reporting template (“CMRT”), standardized by the RMI, to gather sourcing information from its 3TG suppliers in order to identify whether: (i) conflict minerals sourced by such suppliers originated in Covered Countries or CAHRAs; 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”) and its cross-recognized certification programs, which include the London Bullion Metal Association (“LBMA”) Responsible Gold Certification, the Responsible Jewelry Council (“RJC”) Responsible Jewelry Program Chain-of-Custody Certification and other third-party due diligence certification standards.

• In addition, a summary of country of origin information for minerals used in onsemi products that we collected in connection with our RCOI and due diligence efforts is attached hereto as Appendix A.

• The Company utilizes an internal compliance audit to assess and confirm that the due diligence approach followed by the Company is in accordance with OECD Guidance.

• The Company established communication channels with 3TG suppliers to inquire about conflict minerals and alert such entities about the risk of using non-conformant smelters. These channels also serve as grievance mechanisms under our Responsible Minerals Compliance Program.

• OECD Guidance Step 2: Identify and assess risk in the supply chain

• The Company conducts an annual outreach campaign requesting the latest CMRT from each of its identified 3TG suppliers in accordance with its responsible minerals sourcing policy. The Company also sends outreach letters when RMI reports a non-conformant smelter, a high-risk smelter or a smelter that ceased operations.

• The Company maintains a database and process to monitor, collect, manage and aggregate CMRT declarations received from its 3TG suppliers.

• The Company uses the RMI’s facility database report to identify suppliers using smelters that are conformant to a third-party audit program assessing related supply chain risks. Additionally, the Company also utilizes the RMI’s facility database report to perform due diligence and confirm information from its 3TG suppliers.

2

• The Company’s Responsible Minerals Compliance Team (the “RMC Team”) reviews all CMRT responses for completeness and consistency with the latest CMRT revision. As of December 31, 2024, the Company received and reviewed CMRT submissions from its 3TG suppliers.

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

• The RMC Team reviews and updates its own company-level CMRT to identify risk in the supply chain for non-RMAP conformant smelters reported by 3TG suppliers in their submitted CMRTs.

• The Company sends outreach or encouragement letters to 3TG suppliers to remove or replace non-conformant or high-risk smelters. When needed, the Company sends out reminders or escalation emails to request updates.

• The Company conducts a risk assessment of 3TG suppliers, and suppliers are rated using a risk matrix system based on the CMRT submitted. Each supplier is assigned a risk rating ranging from “Low Risk” to “High Risk,” as further described below:

• “Low Risk” means that a supplier is using 100% RMAP conformant smelters.

• “Medium Risk” means that a supplier is using an active or non-conformant smelter but one which is identified as eligible to participate in the RMAP.

• “High Risk” means that a supplier either is using a high-risk smelter or an ineligible entity.

• OECD Guidance Step 4: Carry out an independent third-party audit of smelters’ due diligence practices

• The Company is an active member of RMI, which uses an independent third-party assessment of smelter or refiner management systems and sourcing practices to validate compliance with RMAP standards. The Company relies on RMI due diligence and RMAP audit results, including the RMI RCOI report.

• The RMC Team is a member of the RMI work groups that continue to develop improvements to the RMI programs and tools.

• The Company also supports the RMI Smelter Assessment Fund, which encourages RMAP-eligible smelters and refiners to undergo an independent third-party assessment.

• OECD Guidance Step 5: Report annually on supply chain due diligence

• The Company is an indirect purchaser of conflict minerals, and its due diligence measures provide reasonable, not absolute, assurance regarding the source and chain of custody of conflict minerals. The Company’s due diligence processes seek data from its direct suppliers and those suppliers seek similar information within their supply chains to identify the original sources of the conflict minerals. We also rely to a large extent on information collected and provided by RMI’s independent third-party audit programs. Such sources of information may produce inaccurate or incomplete information and may be subject to fraud. As required, a CMRT is requested from all 3TG suppliers annually to promote a reliable and consistent due diligence process. If a supplier is found to be non-compliant with the Company’s responsible minerals sourcing policy, an escalation process is initiated to determine appropriate remedial measures, which may include removing the supplier from our supply chain.

• The Company prepares and files a conflict minerals report as an exhibit to its Specialized Disclosure Report on Securities and Exchange Commission Form SD with the SEC on an annual basis. The conflict minerals report is made available to the public and posted on the Company’s website at https://www.onsemi.com/site/pdf/Annual-Conflict-Minerals-Report.pdf.

• The Company publicly posts and regularly updates its own company-level CMRT on its website at https://www.onsemi.com/pub/Collateral/CMRTRM.XLSX.

Due Diligence Results

Appendix B sets forth a list of smelters, as provided by the Company’s 3TG suppliers, including mineral type and standard smelter names. As described below, as of December 31, 2024, 100% of such smelters were on the RMAP Conformant Smelter List. Although most of our suppliers provide us with product-level declarations, some of our suppliers continue to provide information at the company level. Declarations at the company level do not limit the information provided on smelters to those specific to the products that the supplier provides for us. As a result of the Company’s continuous due diligence with 3TG suppliers and smelters, information provided by its 3TG suppliers and other information available indicate that all the smelters used were 100% RMAP conformant for the last three consecutive years, as described in the chart below.

The smelter or refiner statuses utilized in the chart have the following definitions:

• “Conformant” means that a smelter has been independently assessed and found conformant with the relevant RMAP standard and is included in the Standard Smelter List.

• “Active” means that a smelter has been engaged in the RMAP program but has not yet been determined to be conformant and is included in the Standard Smelter List.

• “Non-conformant” means that a smelter meets the definition of a smelter or refiner, is identified as an eligible smelter, has been independently assessed and found non-conformant with the relevant RMAP standards and is included in the Standard Smelter List.

For the year ended December 31, 2024, all 3TG smelters were reported to be 100% RMAP conformant, as shown in the table below:

Mitigation of Risk Related to Benefiting Armed Groups

The Company seeks to continually improve its processes and procedures to mitigate the risk that the conflict minerals that it sources benefit armed groups. In particular, the Company has taken a number of steps to improve its due diligence processes, including, but not limited to, the following:

• The Company has incorporated conflict minerals compliance requirements into its supplier handbook for all suppliers.

• The Company has incorporated conflict minerals compliance requirements and checkpoints into its business processes for new product introduction, new supplier qualification and change management.

• The Company reviews and evaluates supplier data that it receives, including by comparison with the RMI’s RCOI report and other available data, with a view to increasing the reliability of its information and processes and the completeness and accuracy of such information.
