Beam Therapeutics Confidential and Anonymous Compliance Hotline

Beam Therapeutics is committed to maintaining an ethical, transparent and legally compliant culture as it conducts its business and advances its mission of developing therapies for patients. Accordingly, Beam-related conduct is expected to adhere to all applicable laws, rules,and regulations, codes and policies. As part of this commitment, Beam asks its employees and business partners to proactively ask questions and seek guidance about, and report suspected violations of, its Code of Business Conduct and Ethics or any of its other policies and procedures, any violation or suspected violation of relevant laws, rules or regulations arising in the conduct of the Beam’s business or occurring on Beam’s property, or any concerns regarding accounting, internal accounting controls or auditing matters.

We believe that the best way to communicate any concerns or questions you may have, or report any issues you may have observed, is to speak directly with your supervisor or management. You should also feel free to contact your manager, the Chief Legal Officer, the Chief Human Resources Officer or the Chief Executive Officer.

If, however, you prefer to anonymously communicate with the Audit Committee of Beam’s Board of Directors, we ask that you use this secure website, which is hosted by a third-party provider. You do not have to provide any identifying data with your message. The provider will encrypt your message and, if you choose to leave a telephone message, anonymize your voice before forwarding it to the Chairperson of the Audit Committee.

You may leave a message using any one of two methods: Secure Web Form and Secure Hotline.
