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, 2023 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 to the functionality or production of a product manufactured (or contracted to be manufactured) by theCompany 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 isaccelerating change in megatrends such as vehicle electrification and safety, sustainable energy grids, industrial automation, and 5G and cloudinfrastructure. With a highly differentiated and innovative product portfolio, onsemi creates intelligent power and sensing technologies that solve theworld’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 ofsuch minerals from the Democratic Republic of the Congo and adjoining countries (“Covered Countries”). The Company’s annual Sustainability Report(the next of which is expected to be released in June 2024), which addresses these concerns and other actions the Company is taking in the area of social
responsibility, is available at 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 2023
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 isutilized.
Conflict minerals are obtained from multiple sources worldwide, and the Company does not desire to eliminate those originating in Covered
Countries. 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. The Company also recognizes the importance of supporting responsible mineral sourcing fromthe Covered Countries so as not to negatively impact the economies of those countries.
1Due Diligence
In accordance with the Conflict Minerals Regulations, the Company conducted a reasonable country of origin inquiry (“RCOI”) designed todetermine 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 continually reviews and updates policies, as appropriate, to reflect the procedures by which the Company and its 3TG
suppliers should conduct due diligence related to conflict minerals. Ethics and Compliance and global supply chain teams review
any changes to the conflict minerals policy or governing documents.

•

The Company established an internal management team to support supply chain due diligence and institute a systematic process.
The internal management team includes appropriate employees within the Company’s quality, purchasing and legal departments.
The sustaining management team consists of quality, ethics, supply chain and legal representatives. Additionally, the Audit
Committee of the Board of Directors of the Company reviews the program on a quarterly basis to track the progress towards the
program’s goals.

•

The Company is a member of the RBA and is a full member of the RMI. Our participation in these organizations allows us to learn
from our peer companies in the electronics industry and provides us with additional insight regarding their conflict minerals plans,
programs and processes.

•

The Company utilized the form conflict minerals reporting template (“CMRT”), standardized by the RMI, to collect sourcing
information from its 3TG suppliers in order to identify whether: (i) conflict minerals sourced by such suppliers originated in
Covered Countries; and (ii) smelters and refiners (collectively, “smelters”) in our supply chain have been validated as conformant inaccordance with the Responsible Minerals Assurance Process (“RMAP”) and cross-recognized certification programs, which include
the London Bullion Metal Association (“LBMA”) Responsible Gold Certification and the Responsible Jewelry Council (“RJC”)
Responsible Jewelry Program Chain-of-Custody Certification.

•

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 RMI developed an audit protocol for verification of entities as conformant with the RMAP in accordance with the OECD
Guidance and in conjunction with complementary traceability schemes in the Covered Countries. The Conformant Smelter List iscomposed of entities that were determined to be conformant with the RMAP and that have been subject to an independent thirdparty audit to assess whether each such entity employed policies, practices and procedures to source conflict-free minerals. onsemi
uses the Conformant Smelter List and any other lists that have been recognized by the RMI, including the LBMA and RJC lists forgold, for making conflict minerals determinations with respect to conflict minerals sourced by the Company. We are a member of the
RMI and have access to the RMI country of origin information for entities on the Conformant Smelter List.

•

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 customers and 3TG suppliers to inquire about conflict minerals and alertsuch entities about the risk of using non-conformant smelters as grievance mechanisms under our conflict minerals complianceprogram.
2••OECD Guidance Step 2: Identify and assess risk in the supply chain•

The Company believes that it has identified all suppliers that provide it with 3TG through its supply chain diligence. The Company
sends an outreach campaign letter requesting the latest CMRT from each of its identified 3TG suppliers every year.

•

The Company employs a third-party web-based software platform to collect, manage, aggregate, and review the completeness of the
CMRT declarations received from its 3TG suppliers. This software ensures the Company has an auditable “chain of custody”
regarding receipt of declarations and information received from suppliers.

•

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

•

The Company’s conflict minerals team reviews all CMRT responses for completeness and consistency with the latest CMRT
revision. As of December 31, 2023, the Company had received and reviewed CMRT submissions from 100% of its 3TG suppliers.

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

The Company’s conflict minerals 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.
•

Outreach or encouragement letters are sent to 3TG suppliers to remove or replace non-conformant smelters. The Company
contacts suppliers and regularly sends out reminder emails to request responses or updates.

•

As a member of the RMI, the Company has access to outreach or encouragement letters, which are also sent directly by theCompany’s conflict minerals team to non-conformant smelters.

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 “Critical Risk,” as further described below:•“Low Risk” means that a supplier is using 100% RMAP conformant smelters with a conflict minerals policy.

•“Medium Risk” means that a supplier is using an active or non-conformant smelter but one which is identified as eligible toparticipate in the RMAP (or otherwise does not meet the criteria for Low Risk above).

•“High Risk” or “Critical Risk” means that a supplier either has no conflict minerals policy or is using an ineligible entity.

•

As of December 31, 2023, 100% of our 3TG suppliers were assigned a “Low Risk” rating for having 100% conformant
smelters declared in their CMRTs, as further described in the “Due Diligence Results” section of this CMR.

At least once per year, or whenever there is a major CMRT revision release, 3TG suppliers receive an email notification through athird-party solution provider or from the conflict minerals compliance team for the Company’s conflict-free minerals campaign,
requesting them to:•continue to source only from RMAP conformant smelters;•

remove or replace non-conformant smelters;•

immediately report any risk: (i) contributing to, or associated with, any violations of the Company’s conflict-free minerals
campaign, or (ii) that may give rise to a significant adverse impact on the Company’s conflict-free minerals campaign; and
3

•
•

•

identify all conflict minerals smelters in their supply chain and report back to the Company a completed and updated
CMRT.

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

As an active RMI member, we benefit from the RMAP, which uses an independent third-party assessment of smelter or refinermanagement systems and sourcing practices to validate compliance with RMAP standards. We have relied on RMI due diligenceand RMAP audit results posted on the RMI website, including the RMI RCOI report.

•

One employee on the Company’s conflict minerals compliance team is a member of the RMI workgroups that continue to develop
improvements to the RMI programs. To that end, the Company approaches, through direct communication and smelter outreach,both the smelters and their customers (i.e., the Company’s suppliers) in our supply chain. The Company also contributes to thought
leadership and supplier training and participates in the relevant workgroups along with peer companies within industry
organizations.

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 conflictminerals. 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 isrequested from all 3TG suppliers annually to promote a reliable and consistent due diligence process. If we determine that a supplierhas not complied with the Company’s conflict minerals policy, the Company will employ an escalation process 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 andExchange Commission Form SD with the SEC on an annual basis. The conflict minerals report is made available to the public andposted 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 athttps://www.onsemi.com/pub/Collateral/CMRTRM.XLSX.

•Conflict minerals due diligence is also available in our annual Sustainability Report posted on the Social Responsibility Webpage.

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, 2023, 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 thecompany level do not limit the information provided on smelters to those specific to the products that the supplier provides to us. As a result of theCompany’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 99.6% RMAP conformant at the end of the 2020 calendar year, 98% for 2021 and 100% for 2022, as
described in the chart below.
4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 isincluded 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 includedin 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.

•“Not eligible” means that an entity does not meet the definition of a smelter or refiner or is otherwise ineligible for the RMAP programand is not included in the Standard Smelter List. This includes any alleged or unknown smelter that requires more research for its RMAP
eligibility.

For the year ended December 31, 2023, 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 productintroduction, new supplier qualification and change management.
5

•

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

•

If a smelter becomes non-conformant at any time, the Company will send an outreach letter directly to such smelter.
