Allegro MicroSystems, Inc. – 2022 Conflict Minerals Report
Introduction
This Conflict Minerals Report of Allegro MicroSystems, Inc. (the “Company”, “Allegro”, “we”, or “our”), for the year ended December 31, 2022 (the “Report”), is presented in compliance with Rule 13p-1 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). This Report should be read in conjunction with the definitions set forth by U.S. Securities and Exchange Commission (“SEC”) within the Form SD – Specialized Disclosure Report – Instructions. “Conflict Minerals” or “3TG” refers to the four specific metals, tantalum, tin, tungsten, and gold, regardless of country of origin or whether they benefit, or finance, armed conflict and violence.
Rule 13p-1 of the Exchange Act imposes reporting obligations for SEC reporting companies whose products contain Conflict Minerals that are necessary to the functionality or production of their products. Such companies must, in good faith, conduct a reasonable country of origin inquiry (the “RCOI”) designed to determine the country of origin of the Conflict Minerals. If the Conflict Minerals necessary for the functionality or production of a company’s products may have originated in the Democratic Republic of the Congo, and adjoining countries (the “Covered Countries”), and may not be solely from recycled or scrap resources, a company must also conduct due diligence on the source and chain of custody of those Conflict Minerals to determine if the Conflict Minerals benefitted, or financed, armed conflict and violence.
For the year ended December 31, 2022, the Company has determined that Conflict Minerals were necessary to the functionality and production of our products and has conducted a RCOI, as described in this Report. Based on the RCOI, some of the Conflict Minerals used in the Company’s products may have originated in the Covered Countries and may not have only originated from scrap and recycled sources. The Company performed due diligence measures on the source and chain of custody of these Conflict Minerals, as described in this Report.
This Report describes our products and the review and diligence process undertaken for products that were manufactured or contracted to be manufactured during calendar year 2022 and that contain Conflict Minerals. Pursuant to the April 29, 2014 “Statement on the Effect of the Recent Court of Appeals Decision on the Conflict Minerals Rule,” issued by Keith F. Higgins, Director, SEC Division of Corporate Finance, the Company is not required to describe its products as “DRC Conflict Free” or “DRC Conflict Undeterminable.” Moreover, the Company is not required to obtain, and has not obtained, an independent private sector audit of this Report.
For important disclosures regarding the website references and forward-looking statements contained in this Report, please see the section of the Report titled “Additional Information.”

Overview of Allegro’s Ethical Minerals Program
We are committed to the ethical and responsible sourcing of minerals and have enacted our Conflict Minerals – 3TG Sourcing Policy to prevent the 3TG procured for manufacturing from directly, or indirectly, benefitting armed groups, violence, or human rights violations in the Covered Countries. Our Conflict Minerals – 3TG Sourcing Policy, as well as our Cobalt and Mica Sourcing Policy are publicly available on our website (https://www.allegromicro.com/en/design-support/quality-and-environment under “Policies and Declarations”). These policies are the foundation for our ethical minerals program and are designed to improve mineral sourcing decisions through:
Installing company-wide programs and procedures supporting the Responsible Minerals Initiative (“RMI”) aimed at eradicating armed conflict, violence, and human right violations.
Mapping mineral supply chains and minerals sources utilizing RCOI data, smelter databases, and the Responsible Minerals Assurance Program (“RMAP”) to identify smelters or refiners (“SORs”) as conformant to the Organization for Economic Co-operation and Development (“OECD”) Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict Affected High Risk Areas (the “OECD Guidance”).
Requiring suppliers to have a policy or program in place that aims to have all 3TG utilized ethically sourced, conflict free and reported to stakeholders within the Conflict Minerals Reporting Template (“CMRT”).
Working to improve 3TG sourcing decisions and communicating with stakeholders concerning 3TG mineral supply chain changes that need attention.
Taking corrective actions to enable ethical sourcing and a conflict-free 3TG supply chain.
When SOR facilities cannot be confirmed or denied as sourcing from Covered Countries, those suppliers may be audited and subjected to an executive decision on future sourcing options.
Reasonable Country of Origin Inquiry
RCOI Process
For the year ended December 31, 2022, we utilized the following process to conduct our RCOI. We conducted an annual survey utilizing the CMRT to survey our supply chain for any Conflict Minerals necessary for production and manufacturing to identify the SOR facilities our suppliers use when manufacturing our products. Any suppliers that may use Conflict Minerals were identified, provided our Conflict Minerals – 3TG Sourcing Policy, the latest version of the CMRT, and were asked to complete and return the CMRT. Submitted supplier CMRTs were then reviewed for accuracy and completeness. Any areas of concern were identified to the supplier for more details and any amendments. The SOR facilities were then cross-checked with the RMI facilities database, which contains the current status of all facilities as active and conformant. For any facilities identified to not be active and conformant to RMAP, or another responsible mineral validation program, we attempted to contact the SOR facility directly to request that the country of origin be identified for the Conflict Minerals used in the manufacturing of our products. As part of that outreach, we encouraged the contacted SOR facility to engage in the RMI’s RMAP. All RCOI surveys and direct communications with SOR facilities were retained within our compliance database and reviewed.
RCOI Results
The results of our RCOI for the year ending December 31, 2022, are as follows:
100% of suppliers identified as utilizing Conflict Minerals that are necessary for the production and manufacturing of our parts provided responses to the CMRT.
144 SOR facilities were identified on supplier’s CMRTs.
Of the 144 facilities, we have reason to believe that 18 may have sourced Conflict Minerals from the Covered Countries and are in conformance with RMAP. Of the 144 facilities, 143 were audited by the RMI and validated against RMAP as active and conformant facilities. One facility fell out of the audit cycle, but this facility is engaged with RMAP, is in progress of being reaudited, and is being evaluated to determine if it is conformant. Three facilities were later dispositioned due to no longer being active and remaining conformant to RMAP. We performed additional activities on these four (4) facilities through supplier engagement and



ongoing monitoring. Our suppliers engaged with the supply chain to ensure the facilities are brought into conformance or removed. The three (3) facilities that became inactive were removed from the supply chain. We are actively monitoring the progress of the final facility’s RMAP audit and will continue to engage with the supplier to ensure RMAP conformance or removal from the supply chain.
Based on the RCOI conducted by the Company described above, we have reason to believe that some of the Conflict Minerals used in the Company’s products may have originated in the Covered Countries and may not have only originated from scrap and recycled sources. Therefore, we exercised due diligence on the source and chain of custody of Conflict Minerals, in accordance with our ethical minerals program.
Design of Allegro’s Ethical Minerals Program and Due Diligence Process
Allegro has implemented management systems and due diligence processes, including an internal written procedure (our “Ethical Minerals Program”) as a key component for supply chain management, compliance disclosures, and reporting as related to the Conflict Minerals necessary to the functionality or production of products that the Company manufactures and contracts to manufacture. Our Ethical Minerals Program is designed to conform with the five-step framework contained in the OECD Guidance. Our Ethical Minerals Program works in connection with our Supplier Code of Conduct, which is publicly available on our website (https://www.allegromicro.com/en/about-allegro/corporate-responsibility).
Ethical Minerals Program
The following is a summary of the steps we take as part of our Ethical Minerals Program, as it related to the OEC Guidance:
Step 1: Maintain strong company management systems
Responsible Mineral Sourcing Policies: We maintain supply chain mineral sourcing policies that are regularly reviewed and updated. The scope of these policies is minerals that originate from conflict affected high risk areas identified by the OECD (“CAHRAs”), including the Covered Countries. These policies are aligned to the OECD Guidance, require our suppliers to have similar policies in place, and establish the importance of responsible mineral supply chains to Allegro. These policies are publicly available on our website (https://www.allegromicro.com/en/design-support/quality-and-environment under “Policies and Declarations”).
Internal Ethical Minerals Team: We established an internal team that is tasked with enforcing our Conflict Minerals – 3TG Sourcing Policy and implementing our Ethical Minerals Program. The Director of Quality Management Systems leads our Ethical Minerals Program, reporting to our Sr. Director of Quality and Reliability. Our internal team is supported by the Sr. Vice President of Operations and Quality. The internal team provides reports every other week to stakeholders and the Director of Quality Management Systems, and quarterly reports to the Sr. Director of Quality and Reliability and the Vice President of Operations and Quality to manage the supply chain. These quarterly reports include any escalations related to nonconformant SORs that cannot be removed from the supply chain, metrics on CMRTS and Extended Minerals Reporting Templates (“EMRTs”), and information on suppliers from whom we have not been able to obtain a CMRT. In 2022, no internal quarterly reporting was necessary regarding nonconformant SORs that cannot be removed from the supply chain or unresponsive CMRTs because we did not have any instances of either of these types of events occurring.
RMI Membership: We are a member of the Responsible Business Alliance (RBA) and a full member of the RMI. As regular participants in RMI’s members-only meetings and work groups, we benefit from industry-wide learning and can engage with other industry stakeholders. An integral part of our Ethical Minerals Program is the RCOI data the RMI provides to us in connection with our risk assessment and due diligence practices.
Supplier Compliance Management System: A third-party management system is maintained by our internal ethical minerals team and is utilized for the approval or rejection of a supplier’s compliance documents, including the CMRT and EMRT. This is a multi-tiered approval system that has numerous controls in place to ensure compliance records are acceptable according to Company policies. This database is used to internally maintain records that are related to the responsible souring of minerals, including annual and ad hoc updates.
Due Diligence Tools: We utilize the latest CMRT published by the RMI to survey our suppliers, map our supply chain, and identify the SORs that process the necessary Conflict Minerals contained in our products and the minerals’ country of origin. Our internal monitoring and control tools are used in connection with our supplier compliance management system to identify when smelters are dispositioned from the RMI’s conformant facilities list and which suppliers utilize those facilities and require engagement and supply chain updates.
Supplier Engagement: To routinely engage with our suppliers, we have established our compliance management system to request annual updates to the CMRT and communicate our Conflict Minerals – 3TG Policy. We have also



established supplier contacts within the ethical minerals team that are directly responsible for supplier outreach. These supplier contacts utilize a report provided every other week with information from our supplier compliance management system to assist with supplier engagement. Other members of the ethical minerals team also engage with suppliers via meetings, email, and phone when additional information is required or updates are needed relating to supply chain mapping, traceability, smelter dispositions, or corrective actions.
Objective Evidence: Documents that are directly related to Conflict Minerals are stored within our management system including the CMRT and EMRT. Our management system also serves as a record retention platform, keeping a historical archive of all past records related to Conflict Minerals.
Company Grievance Mechanism: We implemented a grievance mechanism for our employees, suppliers, and any other stakeholders to report any concerns, anonymously, as they relate to the responsible sourcing of minerals and corporate responsibility. We also encourage our suppliers and any other stakeholder to report any grievances to the RMI. Our corporate grievance mechanism is available publicly on our website (https://investors.allegromicro.com/corporate-governance). The RMI’s grievance mechanism is available on the RMI website (https://mineralsgrievanceplatform.org/).
Step 2: Identify and assess risks in the supply chain
Risk Assessment Tools: Our risk assessment process relies heavily on third-party tools and information systems from the RMI. The third-party tools used for assessing the risks associated with Conflict Minerals are the CMRT, RMI Facilities Database, and RCOI data. These tools are used to verify details on our suppliers’ CMRTs and identify risks from the supply chain map. We have developed the CMRT Checker Tool for crosschecking all SORs across all of our suppliers’ CMRTs against the RMI’s Facilities Database. This tool allows us to monitor the applicable facilities for dispositions, request updates from suppliers when needed, and assess risks in the supply chain. The EMRT is another third-party tool that is used to assess risks in the supply chain as they are related to Cobalt and Mica, allowing for the supply chain to be mapped in a similar capacity to the CMRT.
Annual Survey: Our risk assessment process involves conducting an annual survey of all direct suppliers to identify any Conflict Minerals in our products that may have originated in Covered Countries. This survey is designed to disclose the SORs that processed the Conflict Minerals and the country of origin. When we receive a CMRT from a supplier, it goes through an approval process within our database management system to verify the details as both accurate and complete. If there are any concerns relating to the CMRT’s accuracy or completeness, it is sent back to the supplier requesting additional details be provided. Our database management system sends notifications to customers automatically when it is time to provide an update to the CMRT. This database management system is utilized for annual and ad hoc updates of suppliers’ CMRTs and EMRTs.
Risk Assessment Scope: The scope of our risk assessment includes upholding our Supplier Code of Conduct and Conflict Minerals – 3TG Sourcing Policy. Expectations are communicated to all suppliers within our Supplier Code of Conduct.
Perform Spot Checks: Spot checks are performed at SOR facilities that are not conformant to a responsible mineral sourcing validation program by attempting to have the facility engage with RMAP and allow us to review and audit their due diligence practices, mineral trade routes, chain of custody information, and mineral country of origin information, in person, virtually, or via third party auditing firms that have been approved by the RMI. When a smelting and refining facility does not allow us to perform a spot check in person or virtually, the issue is escalated to our leadership team, and an executive decision is required to send a third-party auditing firm to the facility or remove the facility from the supply chain altogether. The RMI approved third party auditing firms are listed on the RMI’s website (https://www.responsiblemineralsinitiative.org/responsible-minerals-assurance-process/rmap-audit-firm-and-auditor-approval/)
Step 3: Execute a strategy to respond to identified risks
Risk Management Plan: Our risk management plan is heavily reliant on the RMI’s RMAP to validate SOR facilities as active and conformant to the OECD Guidance. RMAP is designed as a due diligence measure that audits the procurement, smelting, and refining practices of facilities processing Conflict Minerals from the Covered Countries, or other CAHRAs, that may not be from recycled or scrap resources. The RCOI data provided by the RMI bimonthly allows for a RCOI to be performed to identify and respond to any location-based risks.
Risk Monitoring: We have a monitoring, measuring and reporting process in place to monitor risks on an ongoing basis. This process is set forth in our written ethical minerals procedure that we utilize as part of our Conflict Minerals Program. Records of supplier CMRTs that have, and have not, been obtained are monitored and reported from the compliance module and within the supplier compliance dashboard. The supplier compliance dashboard produces and distributes a report every other week detailing this information to all internal Conflict Minerals stakeholders.



Reporting Findings: In addition to the biweekly supplier compliance dashboard report that is produced, any findings are presented to the Company’s leadership team in a quarterly report, containing any necessary escalations related to securing the Conflict Minerals supply chain. Escalations are processed by the leadership team to bring suppliers into conformance, otherwise they are removed from the supply chain by enforcing our Supplier Code of Conduct and Conflict Minerals – 3TG Sourcing Policy.
Report Findings to Senior Management: Status updates are provided to our ethical minerals leadership team summarizing the information gathered during our annual survey for Conflict Minerals, results of the risk assessment, due diligence activities, and risk mitigation efforts.
Step 4: Carry out independent third-party audit of SORs’ due diligence practices
Our membership to RMI allows us to utilize RMAP. RMAP is a third-party assessment of the management systems and mineral sourcing practices of SORs for compliance with OECD Guidance and RMAP standards. RMAP is an integral part of our due diligence process.
Our membership to RMI allows us to utilize RCOI data, which is a product of RMI’s RMAP audit activities. RCOI data updates are distributed every other month for use in supply chain traceability.
A member of our ethical minerals team is an active participant in the RMI’s workgroups that are responsible for the ongoing improvement of the RMI’s templates, programs, and initiatives.
Step 5: Report annually on supply chain due diligence
We are not a direct purchaser of 3TG; our supply chain partners purchase 3TG on our behalf to enable us to manufacture our products. We impose our Conflict Minerals – 3TG Sourcing Policy upon our supply chain, requiring them to provide a CMRT annually along with updates, as requested. After performing due diligence on a supplier’s CMRT, the CMRT is approved by the ethical minerals team members and is rolled up into our company-level CMRT, along with the approved CMRTs from our other suppliers. If the supplier CMRT is not approved, the supplier is given the opportunity to comply with our Conflict Minerals – 3TG Sourcing Policy and supplier outreach begins. If supplier outreach is not successful in bringing the supplier into compliance with our Conflict Minerals – 3TG Policy, the CMRT is escalated to the leadership of the ethical minerals team. This process allows for annual updates to our company-level CMRT. If the ethical minerals team leadership is not successful in bringing the supplier into conformance with our Supplier Code of Conduct and Conflict Minerals – 3TG Sourcing Policy, the supplier is removed from the supply chain entirely.
We prepare a Form – Specialized Disclosure Report on Conflict Minerals (“Form SD”) on an annual basis that includes the contents of our company-level CMRT, due diligence description and results, and conclusions. Our Form SD is publicly filed with SEC and available on the SEC’s website at www.sec.gov. In addition, this Report is available on our website at https://www.allegromicro.com/en/about-allegro/corporate-responsibility/sustainability.
Supplier Outreach
Our supplier outreach efforts for the Conflict Minerals necessary for the production or manufacturing of our products for the reporting period ending December 31, 2022, are as follows:
Conducted a survey of all applicable suppliers with the CMRT to identify the SOR facilities within our supply chain that process the Conflict Minerals necessary for the production or manufacturing of our products.
Reviewed the CMRTs provided by suppliers for completeness and accuracy and communicated any concerns with suppliers to obtain additional information and details.
Our response rate for supplier CMRTs was 100% (50 total).
Validated SOR facilities as active and conformant to RMAP.
Monitored, tracked, and reported on suppliers that fell out of conformance with our Conflict Minerals – 3TG Sourcing Policy based on biweekly and quarterly compliance status reports.
Mitigated risks identified on supplier CMRTs by directly communicating with suppliers to engage SOR facilities to participate in RMAP and align to the OECD Guidance.
Our ethical minerals team received quarterly consultations from a third-party consulting firm to review our Ethical Mineral Program and align with industry best practices.
Results of Due Diligence Process
The results of our due diligence efforts for the reporting period ending December 31, 2022, are as follows:



144 SOR facilities were identified utilizing the CMRT. Of those 144 facilities, one facility was identified as not yet being conformant to RMAP.
We requested our suppliers to continue engaging with the SOR facility that was not yet conformant to continue with RMAP and to perform any appropriate corrective actions.
After engaging with our suppliers, we upheld our Supplier Code of Conduct and Conflict Minerals – 3TG Sourcing Policy by successfully removing any inactive facilities from the supply chain, engaging in ongoing monitoring and working with supply chain partners to ensure conformance to RMAP is maintained.
Conclusion
For the period ended December 31, 2022, the Company has concluded, in good faith, that it contracts with others to manufacture and produce parts where Conflict Minerals are necessary for the functionality or production of our products. Based on our RCOI, we have reason to believe that some of the Conflict Minerals used in the manufacturing of our products may have originated in Covered Countries and may not only be from recycled or scrap resources. The Company has exercised due diligence on the source and chain of custody of those Conflict Minerals in accordance with our Ethical Minerals Program and OECD Guidance.
A summary of the results of our due diligence process for the year ended December 31, 2022 is provided in the table below, and a detailed disclosure by Conflict Mineral type of each facility in our supply chain that provides Conflict Minerals, including the company name, unique company identifier, and country location is provided on the following pages.
