This statement is made on behalf of Allegro MicroSystems, Inc. and its direct and indirect subsidiaries(collectively, “Allegro”) pursuant to section 54(1) of the Modern Slavery Act 2015 (the “Act”) and constitutes
Allegro’s Anti-Slavery and Human Trafficking Statement (“Statement”) for the period April 1st, 2021 throughMarch 31st, 2022.

goods, and consumer electronics.
Allegro remain committed to maintaining and improving processes designed to reduce the possibility ofcomplicity in human rights violations as it relates to its operations, supply chain, and products. Allegro
recognizes slavery and human trafficking can occur in many forms, such as: forced labor, child labor, domestic
and indentured servitude, sex trafficking, and workplace abuse. In this Statement, Allegro uses the term“slavery and human trafficking” to encompass the various forms of coerced labor outlawed by the Act.
In complying with all laws, regulations, and rules relevant to its business Allegro endeavors to achieve andmaintain the highest ethical standards. It takes its responsibilities to its stakeholders very seriously, including
those of its employees and the communities in which it operates. All employees of Allegro receive annual
training in Allegro’s Code of Business Conduct and Ethics, which apply to all of those business organizations
under the Allegro corporate umbrella, and specifically addresses anti-slavery and human trafficking, as set
forth here:
Allegro recognizes that modern slavery is a crime and a violation of fundamental human rights. TheCompany has a zero tolerance approach to modern slavery. It does not tolerate modern slavery, toinclude human trafficking, compulsory labor (including child labor), or illegal exploitation in any
form and will take appropriate action if any such violations are discovered. Allegro is committed toacting ethically and with integrity wherever it operates and in implementing and enforcing systems
and controls proportionate to the risk to ensure modern slavery is not taking place in its operations
or supply chain. The Company communicates its zero tolerance approach to suppliers through its
Supplier Excellence Program. We expect our suppliers will hold their own suppliers to the same
standards.
Allegro further encourages compliance to its corporate policies and procedures against anti-slavery andhuman trafficking by way of an Allegro-wide hotline (accessible via either telephone, web, or mobile), allowing

As it pertains to Allegro’s suppliers Allegro has a well-established audit program for its suppliers, called theSupplier Excellence Program. In order to do business with Allegro, suppliers are regularly audited against
specific criteria that includes suppliers’ adherence to the applicable laws and human rights standards. Allegro’s
staff makes site visits at suppliers that might present a higher risk. Human rights violations result in Allegro
ceasing to do business with that supplier and the submission of a report to the appropriate governmental
authority. Although Allegro believes this is the most effective measure it can implement to prevent andidentify violations in the supply chain, in an effort to further inform and influence its suppliers, in March 2021
Allegro published its Supplier Code of Conduct policy, making it available to all suppliers via its Corporate
Responsibility and Sustainability web page (https://www.allegromicro.com/en/about-allegro/corporateresponsibility), and initiated an program whereby it seeks acknowledgement of this policy from its top twentyfive (25) suppliers in terms of annual spend. This effort is intended to make Allegro’s expectations of its
suppliers clear in that it will not accept complicity by its suppliers towards human rights violations, including
slavery and human trafficking.
Finally, as part of its on-going efforts to be transparent with its shareholders, stakeholders, customers,suppliers, and employees, in July 2021, Allegro published its Human Rights policy(https://www.allegromicro.com/en/about-allegro/corporate-responsibility/human-rights).
Thispolicy
expounds those basic freedoms believed to be inherent to all people.
Allegro concludes that its activities comply with the International Bill of Human Rights and with theconventions and principles of the International Labour Organization (Fundamental ILO Conventions).
In continuing these efforts, Allegro continues is affiliation with Responsible Business Alliance (RBA).
Membership in the RBA demonstrates Allegro’s commitment to high labor standards in its business andprovides access to compliance tools to help make improvements where needed. Going forward, Allegro willcontinue to look for additional ways to ensure the values expressed in this Statement are effectively carriedout.
