DESCRIPTION OF BUSINESS	1. DESCRIPTION OF BUSINESS Neuronetics, Inc. (the “Company,” “Neuronetics,” “we,” and similar words) believes that mental health is as important as physical health. The Company’s first commercial product, the NeuroStar Advanced Therapy System (the “System”), is a non-invasive and non-systemic office-based treatment that uses transcranial magnetic stimulation (“TMS”) to create a pulsed, MRI-strength magnetic field that induces electrical currents designed to stimulate specific areas of the brain associated with mood. The System is cleared by the U.S. Food and Drug Administration (the “FDA”) to treat adult patients with major depressive disorder (“MDD”) who have failed to achieve satisfactory improvement from prior antidepressant medication in the current MDD episode. It is also cleared by the FDA as an adjunct for adults with obsessive-compulsive disorder (“OCD”) and for adolescent patients aged 15-21 with MDD. It is also cleared by the FDA to decrease anxiety symptoms in adult patients with MDD that may exhibit comorbid anxiety symptoms (anxious depression). In addition to selling the System and associated treatment sessions to customers, the Company operates Greenbrook TMS Inc. (“Greenbrook”) treatment centers (“Treatment Centers”) across the U.S., offering TMS treatment using the Systems. The Company acquired Greenbrook, a provider of mental healthcare services, pursuant to an Arrangement Agreement effective as of December 9, 2024 (the “Arrangement”). The System is safe, clinically effective, reproducible and precise, and the Company believes it is supported by the largest clinical data set of any competing TMS system. Treatment Centers also acquire SPRAVATO® to treat adults with treatment-resistant depression or depressive symptoms in adults suffering from MDD with acute suicidal ideation or behavior. The Company’s shares trade on the Nasdaq Global Market under the ticker “STIM.” Liquidity and Going concern As of June 30, 2026, the Company had cash and cash equivalents of $19.2 million and an accumulated deficit of $473.2 million. The Company incurred negative cash flows from operating activities of $10.4 million for the six months ended June 30, 2026 and $20.4 million for the year ended December 31, 2025. The Company has incurred operating losses since its inception, and management anticipates that its operating losses will continue in the near term as the Company continues to invest in sales and marketing and product development activities. The Company’s primary sources of capital to date have been from its initial public offering, borrowings under its credit facility, proceeds from its secondary public offerings of common stock (including, without limitation, the ATM Program (as defined below)), and revenues from NeuroStar and Greenbrook. As of June 30, 2026, the Company had $65.0 million of borrowings outstanding under its credit facility, which matures in July 2029. On February 10, 2025, the Company completed a secondary public offering of its common stock in which the Company issued and sold 9,200,000 shares of its common stock, which included shares pursuant to an option granted to the underwriter to purchase additional shares, at a public offering price of $2.25 per share. The Company received net proceeds of $18.9 million after deducting underwriting discounts, commissions and estimated offering expenses. On July 3, 2025, the Company entered into an Equity Distribution Agreement (the “Distribution Agreement”) with Canaccord Genuity LLC, pursuant to which the Company may offer and sell shares of its common stock having an aggregate offering price of up to $50.0 million from time to time through an at-the-market equity offering program (the “ATM Program”). Sales under the Distribution Agreement are made pursuant to the Company’s Registration Statement on Form S-3 (File No. 333-288526), and a related prospectus and prospectus supplement. During the three and six months ended June 30, 2026, the Company sold an aggregate of 6,052,953 shares of its common stock under the ATM Program at an average price of $1.31 per share, generating gross proceeds of $8.0 million. The Company paid aggregate sales commissions of $0.2 million and incurred additional offering-related expenses of $0.2 million. As a result, net proceeds from the offering are $7.6 million. The Company also amortized $0.1 million of shelf related expenses for the ATM Program. As of June 30, 2026, the Company had approximately $33.7 million remaining available for future issuance under the ATM Program. The Company is subject to certain financial covenants under its credit facility, including a liquidity and quarterly trailing twelve-month minimum revenue covenants. On March 12, 2026, the Company amended the terms of its credit agreement to modify the required quarterly revenue covenants through December 31, 2026 and the liquidity covenants through September 30, 2027. As of June 30, 2026 the Company was in compliance with the financial covenants in this agreement. The Company currently projects trailing twelve-month revenue for the period ended March 31, 2027 to be below the minimum required revenue for that period as stated in the credit agreement. Should the Company not be able to meet its March 31, 2027 minimum revenue covenant, the lender may at that time and at its discretion, call the credit facility. Should the lender call the facility, the Company is not projected to have the liquidity required to meet its requirement to pay off the loan. Therefore, substantial doubt exists about the Company’s ability to continue as a going concern. Actions within the Company's control to meet its minimum revenue covenant include improvements to its revenue cycle management, introducing new treatment options at its clinic locations and pursuing new strategies within its NeuroStar business to accelerate sales growth and optimize its product mix. The Company’s ability to meet its liquidity needs, including meeting future revenue and liquidity covenants, is dependent on growth in existing and acquired product and service lines and the realization of synergies related to its acquisition of Greenbrook. However, at this time, these actions do not fully mitigate the risk related to compliance with the revenue covenant for the March 31, 2027 period. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.
