Exhibit 99.1

Neuronetics Reports Second Quarter 2025 Financial and Operating Results

Delivered $38.1 million total revenue in the quarter, representing 18% adjusted pro forma revenue growth

Generated record Greenbrook clinic revenue of $23.0 million in the quarter

Reduced cash used in operations to $3.5 million, beating guidance of under $5 million

In August 2025, received an additional $10 million in funding under the existing debt agreement with Perceptive Advisors LLC

MALVERN, PA., August 5 2025 – Neuronetics, Inc., (NASDAQ: STIM) (the “Company” or “Neuronetics”) 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, today announced its financial and operating results for the second quarter of 2025.

Second Quarter 2025 Highlights

Recent Operational Highlights

“We’re extremely pleased with our second quarter performance, which demonstrated solid revenue growth. Our Greenbrook integration continues to progress well, with record clinic revenue. We also reduced cash used in operations to just $3.5 million, better than our target,” said Keith Sullivan, President and Chief Executive Officer of Neuronetics “Our strong quarterly results are expected to help us achieve positive cash flow from operations in 2025 and I’m confident we’re well-positioned to continue executing on our strategic priorities and drive sustainable growth for the remainder of 2025. We’re also excited to welcome our new Chief Financial Officer, Steve Pfanstiel, who brings over two decades of experience driving growth and profitability at healthcare companies to the team.”

Second Quarter 2025 Financial and Operating Results for the Three Months Ended June 30, 2025

Total revenues for the three months ended June 30, 2025 was $38.1 million, an increase of 132% compared to revenues of $16.5 million in the second quarter of 2024, primarily driven by the acquisition of Greenbrook TMS Inc. (“Greenbrook”). During the quarter, total U.S. revenue increased by 133% and international revenue increased marginally over the second quarter of 2024. The increase in U.S. revenue was primarily attributable to U.S. clinic revenue of $23.0 million, added as a result of the acquisition of Greenbrook, partially offset by the absence of prior year quarter sales to Greenbrook of $2.3 million and an increase of sales of $0.9 million relating to NeuroStar Advanced Therapy Systems and treatment session revenue.

U.S. NeuroStar Advanced Therapy System revenue for the three months ended June 30, 2025 was $3.5 million a decrease of 13% compared to $4.0 million in the second quarter of 2024. For the three months ended June 30, 2025, the Company shipped 41 systems. Following our previously announced realignment of our capital team, the number of units shipped in the second quarter of 2025 was below the prior year quarter, but in line with our focus on strategic higher volume accounts. The average selling price per system (“ASP”) was over $85,000 which was the highest ASP in the past 5 years.

U.S. treatment session revenue for the three months ended June 30, 2025 was $10.8 million, a decrease of 8% compared to $11.7 million in the second quarter of 2024. The decline was primarily attributable to the absence of $2.1 million in treatment session revenue from Greenbrook which was partially offset by an increase in treatment session volume over the prior year quarter. On a pro forma basis U.S treatment session revenue increased 13% compared to $9.6 million in the second quarter of 2024, representing a record quarterly performance.

U.S. clinic revenue, which represents revenue generated by treatment centers from the Greenbrook acquisition, was $23.0 million for the three months ended June 30, 2025.

Gross margin for the second quarter of 2025 was 46.6% compared to the second quarter of 2024 gross margin of 74.0%. The decrease in gross margin was primarily a result of the inclusion of Greenbrook’s clinic business.

Operating expenses during the second quarter of 2025 were $25.8 million, an increase of $5.1 million, or 25%, compared to $20.7 million in the second quarter of 2024, mainly attributable to inclusion of Greenbrook’s general and administrative expenses of $6.1 million, partially offset by savings in sales and marketing expenses.

Net loss for the second quarter of 2025 was $(9.8) million, or $(0.15) per share, as compared to $(9.8) million, or $(0.33) per share, in the second quarter of 2024. Net loss per share was based on 66,180,069 and 30,051,751 weighted average common shares outstanding for the second quarters of 2025 and 2024, respectively.

As of June 30, 2025, the Company held $17.5 million in total cash, consisting of cash and cash equivalents of $11.0 million and $6.5 million of restricted cash, which is compared to $19.5 million as of December 31, 2024. Cash used in operations for the second quarter was $3.5 million.

Company Secures $10 Million in Additional Funding from Perceptive Advisors

In August 2025, Neuronetics received $10.0 million of additional funding under the existing debt agreement with Perceptive Advisors LLC. The Company became eligible for the funds as a result of achieving required revenue conditions under the Tranche 2 funds. Neuronetics also remains eligible for an additional $5 million of Tranche 2 funding, subject to certain customary conditions described in the agreement. The current $2 million minimum liquidity requirement was extended from September 2025 through September 2026 , after which the requirement becomes $5 million.

NeuroStar TMS Shows Strong Real-World Efficacy in Treating Depression in Adolescents and Young Adults

Neuronetics announced the publication of real-world clinical data in Journal of the American Academy of Child & Adolescent Psychiatry Open (JAACAP Open) demonstrating the effectiveness of NeuroStar transcranial magnetic stimulation (TMS) in adolescents and young adults with major depressive disorder. Drawing from the NeuroStar TrakStar Clinical Database—the world’s largest depression outcomes dataset—the study included over 1,200 patients aged 12–21 and revealed that nearly 70% experienced clinically meaningful improvement, with less than 1% reporting worsening symptoms. These results closely mirror outcomes in adults and further validate the FDA-cleared use of NeuroStar as an adjunct therapy in younger populations. With depression affecting one in five adolescents and limited safe treatment options available, NeuroStar TMS offers a much-needed, evidence-based alternative.

Neuronetics Appoints New Chief Financial Officer

The Company appointed Steven Pfanstiel as its new Chief Financial Officer, effective July 15, 2025, succeeding Stephen Furlong. Mr. Pfanstiel brings over 20 years of experience in the healthcare sector, including leadership roles at Marinus Pharmaceuticals, Lifescan, and Johnson & Johnson. Subsequent to Mr. Pfanstiel’s appointment, Mr. Furlong’s separation of service date was accelerated to August 1, 2025.

Business Outlook

For the third quarter of 2025, the Company expects total worldwide revenue between $37.0 million and $39.0 million.

For the full year 2025, the Company maintains its total worldwide revenue to be between $149.0 million and $155.0 million.

For the full year 2025, the Company now expects gross margin to be between 48% and 50%. This update reflects an adjustment in the product mix, with Greenbrook clinical revenues representing a higher percentage of the total revenue vs. prior estimates, as well as the mix of Spravato business between bill and buy and administer and observe. The Company anticipates gross profit margin improvement in the second half as it optimizes the Spravato business mix and as it leverages its fixed infrastructure through continued growth.

For the full year 2025, the Company now expects total operating expenses to be between $100.0 million and $105.0 million vs. the prior guidance of $90 million to $98 million. The updated guidance reflects approximately $20 million in realized annual cost savings from our efforts in 2024 and associated with the Greenbrook integration. The change in guidance for 2025 reflects the need to augment some critical areas, including our claims collections team which is crucial to our cash management, and additional time needed to fully assess and implement other synergies.

The Company expects third quarter cash flow from operations to be in the range of negative $3 million to break-even and turn positive in the fourth quarter of 2025. This compares to our prior guidance of positive cash flow from operations beginning in the third quarter of 2025. The Company now expects year-end 2025 total cash, inclusive of cash, cash equivalents, and restricted cash, to be on the range of $25 million and $28 million, inclusive of the $10 million from the August 2025 Perceptive tranche.

Non-GAAP Financial Measures (Unaudited)

EBITDA is not a measure 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 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:

The pro forma financial information reflects the historical operating results of both the Company and Greenbrook, with all intercompany transactions eliminated. The Adjusted pro forma results further reflect eliminations related to the closure of certain clinics in 2024. The pro forma data does not include the impact of any potential synergies or cost-saving initiatives resulting from the acquisition:

Non-GAAP Financial Measures In addition to financial measures prepared in accordance with accounting principles generally accepted in the United States (“GAAP”), from time to time we may use or publicly disclose certain non-GAAP financial measures in the course of our financial presentations, earnings releases, earnings conference calls, and otherwise. For these purposes, the SEC defines a non-GAAP financial measure as a numerical measure of historical or future financial performance, financial positions, or cash flows that (i) exclude amounts, or is subject to adjustments that effectively exclude amounts, included in the most directly comparable measure calculated and presented in accordance with GAAP in financial statements, and (ii) include amounts, or is subject to adjustments that effectively include amounts, that are excluded from the most directly comparable measure so calculated and presented. Non-GAAP financial measures are provided as additional information to investors to provide an alternative method for assessing our financial condition and operating results. We believe that these non-GAAP measures, when taken together with our GAAP financial measures, allow us and our investors to better evaluate our performance and profitability. These measures are not in accordance with, or a substitute for, GAAP, and may be different from or inconsistent with non-GAAP financial measures used by other companies. These measures should be used in addition to and in conjunction with results presented in accordance with GAAP, and should not be relied upon to the exclusion of GAAP financial measures. Pursuant to the requirements of Regulation G, whenever we refer to a non-GAAP financial measure, we will also generally present, the most directly comparable financial measure calculated and presented in accordance with GAAP, along with a reconciliation of the differences between the non-GAAP financial measure we reference with such comparable GAAP financial measure.
