First Quarter 2026 Financial and Operating Results for the Three Months Ended March 31, 2026

U.S.	$	34,226	$	31,483		9	%
International		228		492		(54	)%

Total revenue for the three months ended March 31, 2026 was $34.5 million, an increase of $2.5 million, or 8%, compared to the three months ended March 31, 2025 revenue of $32.0 million. The increase in revenue was primarily driven by higher U.S. clinic revenue, which increased to $21.5 million in the first quarter of 2026 from $18.7 million in the first quarter of 2025, reflecting strong growth since the Greenbrook acquisition and continued expansion of SPRAVATO^®, including the buy and bill model.

U.S. NeuroStar Advanced Therapy System revenue for the three months ended March 31, 2026 was $3.2 million, an increase of 13% compared to $2.8 million in the first quarter of 2025. For the three months ended March 31, 2026, the Company shipped 34 systems.

U.S. treatment session revenue was $9.1 million for the three months ended March 31, 2026, a decrease from $9.6 million for the three months ended March 31, 2025.

U.S. clinic revenue was $21.5 million for the three months ended March 31, 2026, compared to $18.7 million for the three months ended March 31, 2025, representing an increase of 15%.

Gross margin for the first quarter of 2026 was 46.9% compared to the first quarter of 2025 gross margin of 49.2%. The decrease in gross margin was primarily a result of mix.

Operating expenses during the first quarter of 2026 were $25.1 million, a decrease of $1.6 million, or 6%, compared to $26.8 million in the first quarter of 2025, mainly attributable to savings in general, administrative, sales and marketing expenses.

Net loss for the first quarter of 2026 was $(10.8) million, or $(0.16) per share, as compared to $(12.7) million, or $(0.21) per share, in the first quarter of 2025. Net loss per share was based on 69,589,144 and 61,464,725 weighted average common shares outstanding for the first quarters of 2026 and 2025, respectively.

As of March 31, 2026, the Company held $19.0 million in total cash, consisting of cash and cash equivalents of $13.2 million and $5.8 million of restricted cash, which is compared to $34.1 million as of December 31, 2025. As previously announced, the Company made a one-time principal payment of $5.0 million in March to reduce its debt obligation and ongoing interest expense.

Optum/UHC/UBH expanded its TMS clinical policy to allow Nurse Practitioners to order, supervise, and administer NeuroStar Advanced Therapy

Optum/United Healthcare/United Behavioral Health (“Optum/UHC/UBH”) has expanded its transcranial magnetic stimulation (“TMS”) clinical policy to allow psychiatric mental health nurse practitioners (“PMHNPs”) to order, supervise, and administer NeuroStar Advanced Therapy, significantly broadening access to this non-drug, non-invasive treatment for major depressive disorder (“MDD”). Previously limited to psychiatrists, the updated policy applies to PMHNPs practicing in states with full practice authority and extends access across 26 states and Washington, D.C., reaching approximately 34.8 million covered lives. This milestone policy change is expected to enhance patient access—particularly in underserved communities—by enabling more qualified providers to deliver NeuroStar TMS Therapy, a clinically proven option for patients who have not achieved adequate relief from antidepressant medications.

Business Outlook

For the second quarter of 2026, the Company expects total revenue growth in the mid-single digits.

For the full year 2026, Neuronetics continues to expect:

•

Total revenue between $160 million and $166 million;

•

Gross margin between 47% and 49%;

•

Operating expenses between $100 million and $105 million, inclusive of approximately $8.5 million of non-cash stock-based compensation;

•

Cash flow from operations between negative $13 million and negative $17 million;

About Neuronetics

Neuronetics, Inc. believes 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 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 and associated treatment sessions to customers, Neuronetics operates Greenbrook TMS Inc. (“Greenbrook”) treatment centers across the United States, offering NeuroStar Advanced Therapy for the treatment of MDD and other mental health disorders. NeuroStar Advanced Therapy is the leading TMS treatment for MDD in adults and is backed by what we believe is the largest clinical data set of any TMS treatment system for depression. Greenbrook treatment centers also offer SPRAVATO^® (esketamine) Nasal Spray, a prescription medicine indicated for the treatment of treatment-resistant depression (“TRD”) in adults as monotherapy or in conjunction with an oral antidepressant. It is also indicated for depressive symptoms in adults with MDD with acute suicidal ideation or behavior in conjunction with an oral antidepressant.¹

The NeuroStar Advanced Therapy System is cleared by the U.S. Food and Drug Administration for adults with MDD, as an adjunct for adults with obsessive-compulsive disorder, to decrease anxiety symptoms in adult patients with MDD that may exhibit comorbid anxiety symptoms (anxious depression), and as a first line adjunct for the treatment of MDD in adolescent patients aged 15-21.

Non-GAAP Financial Measures (Unaudited)

EBITDA and Adjusted EBITDA are not measures of financial performance under generally accepted accounting principles in the U.S. (“GAAP”), and should not be construed as a substitute for, or superior to, GAAP net loss. However, management uses both the GAAP and non-GAAP financial measures internally to evaluate and manage the Company’s operations and to better understand its business. Further, management believes that the addition of the non-GAAP financial measures provides meaningful supplementary information to, and facilitates analysis by, investors in evaluating the Company’s financial performance, results of operations and trends. The Company’s calculation of EBITDA and Adjusted EBITDA may not be comparable to similarly designated measures reported by other companies, because companies and investors may differ as to what type of events warrant adjustment.

The following table reconciles reported net loss to EBITDA and Adjusted EBITDA:


	Three Months ended March 31,
	2026			2025
	(in thousands)
Net loss attributable to Neuronetics stockholders’	$	(10,790	)	$	(12,675	)

Loss on extinguishment of debt (Note.2)		539			—

Adjusted EBITDA	$	(6,583	)	$	(8,645	)

Footnotes

Stock-based compensation consists of expenses related to restricted stock units. We exclude these expenses from our non-GAAP financial measures because they are non-cash charges that we do not consider reflective of our core ongoing operational performance. While share-based compensation is a recurring expense and a key part of our employee retention strategy, excluding it allows management and investors to compare our operational profitability more consistently against prior periods and industry peers.

In connection with its $5 million repayment of debt in the first quarter of 2026 to Perceptive Advisors, LLC, the Company recorded a total loss on partial debt extinguishment of approximately $0.5 million. This infrequent and non-recurring expense is removed from EBITDA in order to provide a more accurate reflection of the Company’s core operational performance for the period presented.
