I. Introduction

This is the Conflict Minerals¹ Report of Neuronetics, Inc. ("we," "our," "Neuronetics," or the "Company") prepared for calendar year 2024 in accordance with Rule 13p-1 ("Rule 13p-1") under the Securities Exchange Act of 1934 (the "Act"). Numerous terms in this Report are defined in Rule 13p-1 of the Act and SEC Release No. 34-67716 (August 22, 2012) under the Act (the "Adopting Release"). The reader is referred to these sources for the definitions of defined terms contained herein.

In accordance with Rule 13p-1, we undertook efforts to determine the presence and source of the conflict minerals within our products. The Company designed its efforts in conformity with the internationally recognized due diligence framework set forth in the Organisation for Economic Co-operation and Development ("OECD") Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas² ("OECD Due Diligence Guidance") and related Supplements.

The statements below are based on the activities performed to date in good faith by the Company and are based on the infrastructure and information available at the time of this filing. Factors that could affect the accuracy of these statements include, but are not limited to, incomplete supplier data or available smelter data, errors or omissions by suppliers or smelters, evolving identification of smelters, incomplete information from industry or other third-party sources, continuing guidance regarding the SEC final rules, and other issues.

II. Overview

Company Profile

We are a vertically integrated, commercial stage, medical technology and healthcare company with a strategic vision of transforming the lives of patients whenever and wherever they need help, with the leading neurohealth therapies in the world. We believe that mental health is as important as physical health. As a global leader in neuroscience, Neuronetics is delivering more treatment options to patients and physicians by offering exceptional in-office treatments that produce extraordinary results. NeuroStar Advanced Therapy ("NeuroStar Therapy") is a non-drug, noninvasive treatment that can improve the quality of life for people suffering from neurohealth conditions when traditional medication has not helped. In addition to selling the NeuroStar Advanced Therapy System (the "NeuroStar System") and associated treatment sessions to customers, Neuronetics operates Greenbrook TMS Inc. ("Greenbrook") treatment centers across the United States, offering NeuroStar Therapy, Spravato^®, and other treatment modalities for the treatment of major depressive disorder ("MDD") and other mental health disorders.

NeuroStar Therapy is indicated for the treatment of depressive episodes and for decreasing anxiety symptoms for those who may exhibit comorbid anxiety symptoms in adult patients suffering from MDD and who failed to achieve satisfactory improvement from previous antidepressant medication treatment in the current episode. It is also cleared by the U.S. Food and Drug Administration as an adjunct for adults with obsessive-compulsive disorder and for adolescent patients aged 15 to 21 with MDD. Neuronetics is committed to transforming lives by offering an exceptional treatment that produces extraordinary results.

We are subject to this rule as we have determined that, during 2024, conflict minerals were likely necessary to the functionality or production of products we manufactured or contracted to manufacture. The Company, as a purchaser of component parts, is many steps removed from the mining of conflict minerals. We do not purchase raw ore or unrefined conflict minerals and we conduct no purchasing activities directly in the DRC or adjoining countries.

Conflict Minerals Policy

The Company developed a policy statement to support the goals expressed by Congress in enacting Section 1502 of the Dodd-Frank Wall Street Reform and Consumer Protection Act. The policy highlights the Company's commitment to complying with the reporting and due diligence obligations required by the SEC rule and the Company's expectations from its suppliers. In addition, the policy includes language encouraging suppliers to source responsibly. The policy resides on our corporate website at http://ir.neuronetics.com/corporate-governance/highlights.

Reasonable Country of Origin Inquiry Information

We have conducted a good faith reasonable country of origin inquiry ("RCOI") to determine whether the necessary conflict minerals originated in the DRC or an adjoining country or came from recycled or scrap sources.

The Company's RCOI process included reviewing the products manufactured or contracted to be manufactured during the Reporting Period to identify products that should be deemed in-scope as described by the Adopting Release and conducting an inquiry of our direct suppliers of the in-scope products using the Responsible Minerals Initiative's ("RMI") Conflict Minerals Reporting Template ("CMRT"). Based on the results of our RCOI which indicated sourcing from the DRC or an adjoining country, we exercised due diligence on the source and chain of custody of the conflict minerals in accordance with the OECD Due Diligence Guidance. Our due diligence efforts are discussed further in this Conflict Minerals Report.

IV. Product Description; Processing Facilities

Product Description - Our business is managed and reported on a product basis as follows:

Our current products include our NeuroStar Advanced Therapy System used to treat psychiatric disorders. All of our revenues are currently derived from sales of our NeuroStar Advanced Therapy System, accessories, components and related services in the United States and select international markets. Each of our current products is, and our future products will be, designed to address significant unmet clinical needs in the treatment of mental health.

Processing Facilities - Based on our due diligence process and the information received from our suppliers, the following facilities were identified by the Company's suppliers as the smelters and refiners of the tin, tantalum, tungsten and/or gold present in and necessary to the functionality of products manufactured by the Company in the calendar year ended December 31, 2024. The information from our suppliers is still evolving and may contain company-level declarations. As such, this smelter list is presented in good faith as the best information we have to date. This list may contain smelters that are not in our supply chain and/or there may be other smelters not yet identified in our due diligence process. We will continue to update the list as our information and the relevant third-party data from RMI, LBMA, and RJC improves.

V. Future Due Diligence

We will continue to communicate our expectations and information requirements to our direct suppliers. Over time, we anticipate that the amount of information available globally on the traceability and sourcing of these ores will increase and improve our knowledge. We will continue to make inquiries to our direct suppliers and undertake additional risk assessments when potentially relevant changes in facts or circumstances are identified. If we become aware of a supplier whose due diligence needs improvement, we may continue the trade relationship while that supplier improves its compliance program. We expect our suppliers to take similar measures with their suppliers to ensure alignment throughout the supply chain.

In addition to those above, the Company will undertake the following steps during the next compliance period:
