Neuronetics (STIM) grows sales as going concern risk emerges under debt covenants

(Moderate)
(Neutral)
Form Type
10-Q

Rhea-AI Filing Summary

Neuronetics, Inc. reported higher revenues but continued losses for the quarter and six months ended June 30, 2026. Total revenue was $41.6 million for the quarter, up from $38.1 million, and $76.0 million for the first half of 2026, up from $70.1 million, driven mainly by growth in Greenbrook clinic revenue, which contributed about two-thirds of sales. Gross profit rose to $21.2 million for the quarter and $37.4 million year-to-date, while operating expenses declined, leading to a smaller operating loss.

Net loss attributable to stockholders narrowed to $3.4 million for the quarter and $14.2 million year-to-date, compared with $10.1 million and $22.8 million in the prior-year periods. Operating cash outflow improved to $10.4 million for the first half of 2026, but cash and cash equivalents declined to $19.2 million, with $65.0 million of debt outstanding under the Perceptive Facility. Management discloses substantial doubt about the company’s ability to continue as a going concern due to projected failure of a revenue covenant for the period ending March 31, 2027, which could allow lenders to call the credit facility. Neuronetics raised $7.6 million net through its at-the-market equity program during the quarter and remained in covenant compliance as of June 30, 2026.

Positive

  • Net loss improved to $3.5 million for the quarter and $14.2 million year-to-date, compared with $9.8 million and $22.5 million in the prior-year periods, reflecting higher gross profit and lower operating expenses.
  • Operating cash outflow nearly halved to $10.4 million for the first six months of 2026 from $20.5 million a year earlier, indicating better cash efficiency despite ongoing losses.
  • Neuronetics successfully raised $7.6 million in net proceeds via its at-the-market equity program, supporting liquidity while remaining in compliance with credit facility covenants as of June 30, 2026.

Negative

  • Management states that substantial doubt exists about the company’s ability to continue as a going concern due to projected failure of the March 31, 2027 revenue covenant, which could allow the lender to call the $65.0 million credit facility.
  • The company remains highly leveraged, with $65.0 million of outstanding principal and $4.4 million of interest expense in the first half of 2026, contributing significantly to ongoing net losses.
  • Despite improved trends, Neuronetics generated a net loss of $14.2 million and used $10.4 million of cash in operating activities in the first half of 2026, while cash and cash equivalents fell to $19.2 million.

Filing Explained

The completed ATM sales increased outstanding shares to 76.2 million by June 30, 2026, reducing existing holders’ percentage ownership; $33.7 million of capacity remains.

Neuronetics’s Form 10-Q, an unaudited quarterly report, states that it sold and issued $7.6 million net through its ATM program during the six months ended June 30, 2026, including 6,052,953 new common shares; this increases the share count and dilutes existing holders’ percentage ownership.

An at-the-market program permits gradual sales of new shares at prevailing market prices. The filing reports approximately $33.7 million still available for future issuance as of June 30, 2026; that amount is remaining capacity, not additional shares already sold or proceeds already received.

The filing reports 76,193 thousand common shares issued and outstanding at June 30, 2026, compared with 68,994 thousand at December 31, 2025, while the company remained in compliance with its credit-facility covenants at the quarter-end date.

going concern financial
"Therefore, substantial doubt exists about the Company’s ability to continue as a going concern."
Going concern is the accounting assumption that a company will keep operating and meeting its obligations for the foreseeable future. The phrase matters most when a company or its auditors disclose substantial doubt about it, a formal warning that the business may not have enough resources to continue without raising money, restructuring, or selling assets. That language in a filing or press release signals elevated financial risk.
at-the-market equity offering program financial
"through an at-the-market equity offering program (the “ATM Program”)."
A program that lets a company sell newly issued shares directly into the open market at whatever the current trading price is, usually through a broker, and do so gradually over time instead of all at once. Investors care because it can dilute existing ownership and put steady selling pressure on the stock price, while giving the company a flexible, on-demand way to raise cash — like adding small amounts of water to a pool rather than dumping in a bucket.
Perceptive Facility financial
"The Perceptive Facility permits the Company to borrow up to an aggregate amount of $90.0 million"
sales-type leases financial
"Certain customers have purchased the Systems on a rent-to-own basis. The lease term is two to four years"
A sales-type lease is when the owner of an asset treats a long-term lease more like a sale: the owner records the lease as if it sold the asset and recognizes any immediate profit, while the buyer records a financed purchase. Think of it as selling a car but letting the buyer pay over time with the seller recording a sale now. Investors care because it changes reported revenue, profit, and asset balances, which can affect valuation and cash-flow analysis.
Employee Retention Credit financial
"The Coronavirus Aid, Relief and Economic Security Act provided an employee retention credit (the “ERC”)"
A government-provided payroll tax credit that reimburses employers for a portion of wages paid to staff during qualifying downturns or disruptions, designed to encourage businesses to keep employees on the payroll. For investors, it matters because the credit improves a company’s cash flow and reduces payroll expenses—like a temporary government subsidy that boosts short-term profits and may change the company’s reported tax liabilities and cash reserves, which can affect valuation and risk assessments.

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

7

Table of Contents

NEURONETICS, INC.

Notes to Interim Consolidated Financial Statements

(Unaudited)

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.

2.     BASIS OF PRESENTATION

The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”). Any reference in these notes to applicable guidance is meant to refer to U.S. GAAP as found in the Accounting Standards Codification (“ASC”) and Accounting Standards Updates (“ASUs”) promulgated by the Financial Accounting Standards Board (the “FASB”).

Basis of Consolidation

The consolidated financial statements of the Company are presented in U.S. dollars and include the accounts of the Company and its subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation.

The Company consolidates entities in which it has a controlling financial interest based on either the variable interest entity (“VIE”) or voting interest model (“VOE”). The Company is required to first apply the VIE model to determine whether it holds a variable interest in an entity, and if so, whether the entity is a VIE. ASC Topic 810, Consolidation ("Topic 810") defines the criteria for determining the existence of VIEs and provides guidance for consolidation.

An entity is considered to be a VIE if (i) the entity does not have enough equity to finance its own activities without additional support, (ii) the entity's at-risk equity holders lack the characteristics of a controlling financial interest, or (iii) the entity is structured with non-substantive voting rights. The primary beneficiary of a VIE is the party that has the power to direct the activities that most significantly impact the performance of the entity and the obligation to absorb losses or the right to receive benefits that could potentially be significant to

8

Notes to Interim Consolidated Financial Statements

(Unaudited)

the entity. The primary beneficiary is required to consolidate the VIE for financial reporting purposes. A VIE can have only one primary beneficiary but may not have a primary beneficiary if no party meets the criteria described above.

If the Company determines it does not hold a variable interest in a VIE, the Company applies the VOE model. To the extent the entity does not meet the definition of a VIE, Topic 810 guidance for voting interest entities is applied. The usual condition for a controlling financial interest, and therefore consolidation by the Company, is ownership of a majority voting interest of a corporation or a majority of kick-out rights for a limited partnership. The Company has determined that all its subsidiaries are VOEs primarily because it holds a majority voting interest in the entities.

Interim Consolidated Financial Statements

The accompanying unaudited interim consolidated financial statements have been prepared from the books and records of the Company in accordance with U.S. GAAP for interim financial information and Rule 10-01 of Regulation S-X promulgated by the U.S. Securities and Exchange Commission (the “SEC”), which permit reduced disclosures for interim periods. All adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of the accompanying consolidated balance sheets and consolidated statements of operations and stockholders’ equity and consolidated cash flows have been made. Although these interim consolidated financial statements do not include all of the information and footnotes required for complete annual consolidated financial statements, management believes the disclosures are adequate to make the information presented not misleading. Unaudited interim consolidated statements of operations for the three and six months ended June 30, 2026 and interim consolidated statements of cash flows for the six months ended June 30, 2026 are not necessarily indicative of the results that may be expected for the full year. Unaudited interim consolidated financial statements and footnotes should be read in conjunction with the audited consolidated financial statements and footnotes included in the Company’s Annual Report on Form 10-K filed with the SEC on March 17, 2026, wherein a more complete discussion of significant accounting policies and certain other information can be found.

Reclassifications

Certain prior period amounts have been reclassified for comparative purposes.

Currency Risk

Currency risk is the risk to the Company’s earnings that arises from fluctuations in foreign exchange rates and the degree of volatility of those rates. The Company has minimal exposure to currency risk as substantially all of the Company’s revenue, expenses, assets and liabilities are denominated in U.S. dollars. The Company pays certain vendors and payroll costs in Canadian dollars from time to time, but due to the limited size and nature of these payments, it does not give rise to significant currency risk.

Use of Estimates

The preparation of financial statements in accordance with U.S. GAAP and the rules and regulations of the SEC requires the use of estimates and assumptions, based on judgments considered reasonable, which affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. The Company bases its estimates and assumptions on historical experience, known trends and events and various other factors that management believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Although management believes its estimates and assumptions are reasonable when made, they are based upon information available at the time they are made. Management evaluates the estimates and assumptions on an ongoing basis and, if necessary, makes adjustments. Due to the risks and uncertainties involved in the Company’s business and evolving market

conditions, and given the subjective element of the estimates and assumptions made, actual results may differ materially from estimated results.

3.     SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The Company’s complete summary of significant accounting policies can be found in “Summary of Significant Accounting Policies” in the audited consolidated financial statements included in the Company’s Annual Report on Form 10-K filed with the SEC on March 17, 2026.

4.     RECENT ACCOUNTING PRONOUNCEMENTS

In December 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures (“ASU 2023-09”), which requires public business entities to disclose specific categories in the rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold. ASU 2023-09 is effective for annual periods beginning after December 15, 2024. ASU 2023-09 was adopted in the annual period ended December 31, 2025 using the retrospective method. Accordingly, we have expanded our consolidated financial statement disclosures to comply with the guidance.

In November 2024, the FASB issued ASU 2024-03, Income Statements–Reporting Comprehensive Income–Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses (“ASU 2024-03”), which requires enhanced disclosure of income statement expense categories to improve transparency and provide financial statement users with more detailed information about the nature, amount, and timing of expenses impacting financial performance. ASU 2024-03 is effective for the Company for the annual reporting period beginning after December 15, 2026, and interim periods beginning after December 15, 2027. Early adoption is permitted. The amendments in ASU 2024-03 may be adopted either on a prospective basis to financial statements issued for reporting periods after the effective date or on a retrospective basis to all periods presented. The Company is currently evaluating the impact of the adoption of ASU 2024-03 on its consolidated financial statements and related disclosures.

In July 2025, the FASB issued ASU 2025-05, Measurement of Credit Losses for Accounts Receivable and Contract Assets. The guidance provides a practical expedient that an entity may assume that conditions as of the balance sheet date remain unchanged over the remaining life of the asset when estimating expected credit losses for current accounts receivable and current contract assets arising from revenue transactions from contracts with customers. The guidance is effective in the first quarter of 2026 with early adoption permitted, to be applied on a prospective basis. The Company adopted this guidance in the first quarter of 2026. The adoption did not have a material impact on the Company’s consolidated financial statements and related disclosures.

In September 2025, the FASB issued ASU 2025-06, Intangibles—Goodwill and Other—Internal-Use Software Targeted Improvements to the Accounting for Internal-Use Software. The amendments modify the accounting for internal-use software development costs by replacing the existing project stage framework with a principles-based model for determining when capitalization of development costs should begin. The guidance is effective for annual reporting periods beginning after December 15, 2027, including interim periods within those annual reporting periods. Early adoption is permitted. The Company is currently evaluating the impact that adoption of this guidance will have on its consolidated financial statements.

Other than the items noted above, there have been no new accounting pronouncements not yet effective or adopted in the current year that we believe have a material impact, or potential material impact, to our unaudited interim consolidated financial statements.

6.     FAIR VALUE MEASUREMENT AND FINANCIAL INSTRUMENTS

The carrying values of cash equivalents, accounts receivable, prepaids and other current assets, and accounts payable on the Company’s balance sheets approximated their fair values as of June 30, 2026 and December 31, 2025 due to their short-term nature. The carrying values of the Perceptive Facility (as defined below) approximated its fair value as of June 30, 2026 and December 31, 2025 due to its variable interest rate. The carrying value of the Company’s notes receivable approximated its fair value as of June 30, 2026 and December 31, 2025 due to its variable interest rate.

NEURONETICS, INC.

Notes to Interim Consolidated Financial Statements

(Unaudited)

Certain of the Company’s financial instruments are measured at fair value using a three-level hierarchy that prioritizes the inputs used to measure fair value. This hierarchy maximizes the use of observable inputs and minimizes the use of unobservable inputs. The three levels of inputs used to measure fair value are as follows:

Level 1:

Inputs are quoted prices for identical instruments in active markets.

Level 2:

Inputs are quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; or model-derived valuations whose inputs are observable or whose significant value drivers are observable.

Level 3:

Inputs are unobservable and reflect the Company’s own assumptions, based on the best information available, including the Company’s own data.

The following tables set forth the carrying amounts and fair values of the Company’s financial instruments as of June 30, 2026 and December 31, 2025 (in thousands):

10.     LEASES

Lessee:

The Company has operating leases for its corporate headquarters, Treatment Centers, a training facility, and office equipment. The corporate headquarters is located in Malvern, Pennsylvania, where the Company leases an approximately 32,000 square foot facility comprising office and warehouse space.

In 2025, the Company executed a lease modification for its Malvern, Pennsylvania facility, extending the lease term through June 2033.

The Company leases an approximately 9,600 square foot facility in Charlotte, North Carolina as a training facility for the Systems. The lease ends in September 2027. The Company has an option to extend the lease on its training facility for an additional one-year term; however, the Company has determined it is not reasonably certain to exercise the option at this time after assessing contract, asset, entity and market conditions present upon lease commencement.

The Company has lease agreements related to its Treatment Centers. These lease agreements range from month-to-month to six years in length.

Operating lease rent expense was $2.4 million and $2.1 million for the three months ended June 30, 2026 and 2025, respectively and $4.9 million and $4.4 million for the six months ended June 30, 2026 and 2025, respectively. As of June 30, 2026, the weighted average remaining lease term of operating leases was 6.0 years, and the weighted average discount rate was 12.0%.

As of June 30, 2026 and December 31, 2025 the carrying amount of the lease receivables was $0.3 million, for both periods. The Company does not have any unguaranteed residual assets.

Lessor operating leases:

The Systems leased to customers subsequent to January 1, 2019 for which collection is not probable are accounted for as operating leases. For the three months ended June 30, 2026 and 2025, the Company recognized operating lease income of $0.06 million and $0.05 million, respectively. For the six months ended June 30, 2026 and 2025, the Company recognized operating lease income of $0.1 million, for both periods.

The Company maintained rental equipment, net, of $0.1 million for both June 30, 2026 and December 31, 2025, which are included in property and equipment, net on the consolidated balance sheets. Rental equipment depreciation expense was $0.01 million and $0.14 million for the three months ended June 30, 2026 and 2025, respectively and $0.03 million and $0.16 million for the six months ended June 30, 2026 and 2025, respectively.

11.     PREPAID COMMISSION EXPENSE

The Company pays a commission on both System sales and treatment session sales. Since the commission paid for the System sales is not commensurate with the commission paid for treatment sessions, the Company capitalizes commission expense associated with the System commissions paid that is incremental to specifically anticipated future treatment session orders. In developing this estimate, the Company

15

Table of Contents

NEURONETICS, INC.

Notes to Interim Consolidated Financial Statements

(Unaudited)

considered its historical treatment session sales and customer retention rates, as well as technology development life cycles and other industry factors. These costs are periodically reviewed for impairment.

The System commissions are deferred and amortized on a straight-line basis over a seven year period equal to the average customer term, which the Company deems to be the expected period of benefit for these costs.

On the Company’s consolidated balance sheets, the current portion of capitalized contract costs is presented in current portion of prepaid commission expense, while the long-term portion is included in prepaid commission expense. Amortization expense was $0.8 million for both of the three months ended June 30, 2026 and 2025 and $1.6 million for both of the six months ended June 30, 2026 and 2025.

13.     REVENUE AND DEFERRED REVENUE

Contract terms typically require payment upon shipment or installation of the System and additional payments as access codes for treatment sessions are delivered, which can span several years after the System is first delivered and installed. The timing of revenue recognition compared to billings and cash collections typically results in accounts receivable. However, sometimes customer advances and deposits may be required for certain customers and are recorded as contract liabilities (deferred revenue). For multi-year agreements, the Company generally invoices customers annually at the beginning of each annual coverage period and recognizes revenue over the term of the coverage period. Deferred revenue also includes amounts received in advance of the Company completing performance obligations in relation to the research collaboration agreement with Compass Pathways on COMP360 psilocybin for treatment resistant depression.

As of June 30, 2026, the Company expects to recognize approximately the following percentages of deferred revenue by year:

Perceptive Credit Facility

On July 25, 2024, the Company entered into a Credit Agreement and Guaranty with Perceptive Credit Holding IV, LP (“Perceptive”) as collateral agent and other lenders defined in the agreement (the “Perceptive Facility”) which was used to partially repay the Company’s previous $60.0 million credit facility with SLR Investment Corp. (formerly known as Solar Capital Ltd.).

17

Table of Contents

NEURONETICS, INC.

Notes to Interim Consolidated Financial Statements

(Unaudited)

The Perceptive Facility permits the Company to borrow up to an aggregate amount of $90.0 million in three tranches of term loans, a “Tranche 1 Loan”, a “Tranche 2 Loan” and a “Tranche 3 Loan.” On July 25, 2024, the Company borrowed an aggregate amount of $50.0 million, which was the aggregate amount available under the Tranche 1 Loan. Under the Tranche 2 Loan, the Company was permitted to borrow, at its election, up to an aggregate amount of $15.0 million (i) upon the Company achieving a specified amount of trailing twelve months net revenue, and (ii) assuming there had been no event of default under the Perceptive Facility prior to such election. The Tranche 2 Loan was available until January 31, 2026. Under the Tranche 3 Loan, the Company was permitted to borrow, at the consent of the Majority Lenders (as defined in the Perceptive Facility), up to an aggregate amount of $25.0 million. The Tranche 3 Loan was available until June 30, 2026. There are no scheduled repayments of the principal on the Tranche 1 Loan, the Tranche 2 Loan or the Tranche 3 Loan prior to the maturity date. All amounts borrowed under the Perceptive Facility are due on July 25, 2029.

Each of the Tranche 1 Loan, the Tranche 2 Loan and the Tranche 3 Loan accrues interest from the date of borrowing through the date of repayment at a floating per annum rate of interest equal to the sum of 7.00% plus the greater of (a) 4.50% and (b) One-Month Term SOFR (as defined in the Perceptive Facility).

If the Company prepays Tranche 1 Loan, the Tranche 2 Loan, or the Tranche 3 Loan prior to the maturity date, the Company will also be required to pay prepayment fees to Perceptive equal to 6% of the principal amount of such term loan then-prepaid if prepaid on or before the first anniversary of the closing date, 5% of the principal amount of such term loan then-prepaid if prepaid after the first anniversary and on or before the second anniversary of the closing date, 4% of the principal amount of such term loan then-prepaid if prepaid after the second anniversary and on or before the third anniversary of the closing date, and 3% of the principal amount of such term loan then-prepaid if prepaid after the third anniversary and on or before the fourth anniversary of the closing date.

The Company’s obligations under the Perceptive Facility are secured by a first priority security interest in substantially all of the Company’s assets, including its intellectual property. The Perceptive Facility requires the Company to comply with a quarterly minimum trailing revenue covenant commencing March 2025 and a minimum liquidity covenant as well as affirmative and negative covenants.

The Perceptive Facility contains events of default, including, without limitation, events of default upon: (i) failure to make payment pursuant to the terms of the agreement; (ii) violation of covenants; (iii) material adverse changes to the Company’s business; (iv) insolvency; (v) material cross-defaults; (vi) significant judgments, orders, or decrees for payments by the Company; (vii) incorrectness of representations and warranties; (viii) significant adverse events related to the Employee Retirement Income Security Act of 1974; (ix) failure by the Company to be registered with the SEC in good standing; or (x) failure by the Company to maintain a valid and perfected lien on the collateral securing the borrowing.

As consideration for the Perceptive Facility, the Company agreed to issue to Perceptive warrants to purchase up to 1,462,500 shares of the Company’s common stock, with a warrant exercisable into 1,125,000 shares of the Company’s common stock issued on the closing date (the “Initial Warrant”). The per share exercise price for the Initial Warrant is equal to the lower of (x) the 10-day volume weighted average price of the Company’s common stock on the business day immediately prior to the closing date and (y) the 10-day volume weighted average price of the common stock ended on August 31, 2024. In addition to the Initial Warrant, an additional warrant was issued for 225,000 shares of common stock concurrently with the borrowing of the Tranche 2 Loan. The per share exercise price for the additional warrant will be equal to the exercise price of the Initial Warrant. Each warrant will be exercisable, in whole or in part, until the tenth anniversary of the applicable date of issuance.

Effective as of December 9, 2024, the Company amended the Perceptive Facility and borrowed against the Tranche 3 Loan in a principal amount of $10.0 million and used the proceeds thereof to finance, in part, the operations of the combined enterprise after the acquisition of Greenbrook and the related transactions

included in the Arrangement. As consideration for Tranche 3 Loan borrowing, the Company issued warrants to purchase 600,000 shares of the Company’s common stock at a per share exercise price of $0.94.

The Company calculated the issuance date fair value of the warrants using the Black-Scholes option pricing model, which resulted in a fair value of $2.6 million. Accordingly, the Company allocated the proceeds from the Perceptive Facility on a relative fair value basis resulting in $2.5 million allocated to the warrants.

On March 26, 2025, the Company entered into Amendment No. 2 to Credit Agreement and Guaranty by and between the Company, as the borrower, and Perceptive, in its capacities as administrative agent for the lenders and the majority lender, in which the parties agreed to revise the net revenue covenant to align with the Company’s pre-existing operating plan for the first quarter of 2025.

On August 1, 2025, the Company entered into Amendment No. 3 to Credit Agreement and Guaranty (the “Perceptive Third Amendment”). Pursuant to the Perceptive Third Amendment, the Company borrowed $10.0 million under Tranche 2, lowered the minimum liquidity balance requirement to $2.0 million through September 30, 2026, and issued Perceptive a warrant certificate exercisable into 225,000 shares of the Company’s common stock.

On January 15, 2026, the Company entered into Amendment No. 4 to Credit Agreement and Guaranty (the “Perceptive Fourth Amendment”). The Perceptive Fourth Amendment amended the Perceptive Facility to modify the requirements of subsidiaries joining as an obligor and subsidiary guarantor thereunder.

On March 12, 2026, the Company entered into Amendment No. 5 to the Credit Agreement and Guaranty (the “Perceptive Fifth Amendment”). Under the Perceptive Fifth Amendment, Neuronetics made a one-time principal payment of $5.0 million, and Neuronetics and Perceptive agreed to adjustments to the existing debt covenants. In connection with the amendment, the Company incurred a prepayment penalty of $0.3 million, which, together with the proportional write-off of unamortized debt issuance costs and discounts, resulted in a total loss on partial debt extinguishment of approximately $0.5 million for accounting purposes.

As of June 30, 2026, the Company had $65.0 million of borrowings outstanding under the Perceptive Facility, which has a final maturity in July 2029. The interest rate on borrowings under the credit facility is variable and resets monthly.

The Company was in compliance with the covenants under the Perceptive Facility as of June 30, 2026.

15.     COMMON STOCK

Common Stock Offering

On July 3, 2025, the Company entered into the Distribution Agreement, 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 the ATM Program. Sales under the Distribution Agreement will be 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 approximately $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.There were no sales under the ATM Program for the three and six months ended June 30, 2025.

16.     LOSS PER SHARE

The Company’s basic loss per common share is computed by dividing the net loss by the weighted average number of shares of common stock outstanding during the period. The Company’s restricted stock awards (non-vested shares) are issued and outstanding at the time of grant, but are excluded from the Company’s computation of weighted average shares outstanding in the determination of basic loss per share until vesting occurs.

A net loss cannot be diluted; so, when the Company is in a net loss position, basic and diluted loss per common share are the same. If, in the future, the Company achieves profitability, the denominator of a diluted earnings per common share calculation will include both the weighted average number of shares outstanding and the number of common stock equivalents, if the inclusion of such common stock equivalents would be dilutive. Dilutive common stock equivalents potentially include warrants, stock options, non-vested restricted stock awards and non-vested performance restricted stock units (“PRSUs”) using the treasury stock method, along with the effect, if any, from the potential conversion of outstanding securities, such as convertible preferred stock.

2026 Equity Incentive Plan

On May 28, 2026 (the “Stockholder Approval Date”), the Company’s stockholders approved the 2026 Equity Incentive Plan (the “2026 Plan”), which was previously approved by the Company’s Board of Directors (the “Board”) on March 18, 2026, and which provides for the issuance of the number of shares of common stock that were available for issuance under the 2018 Plan as of the Stockholder Approval Date. The number of shares available for issuance under the 2026 Plan may be increased annually at the discretion of the Board from January 1, 2027 through January 1, 2036, by an amount equal to 4% of the Company’s outstanding shares of common stock on the applicable date. The 2026 Plan permits the grant of stock options, stock appreciation rights, restricted stock units, PRSUs, and other stock-based awards to the Company’s directors, employees, consultants, and other eligible service providers. The terms and conditions of awards granted under the 2026 Plan are determined by the Board. As of June 30, 2026, 6.0 million shares remained available for future issuance under the 2026 Plan.

2018 Equity Incentive Plan

In June 2018, the Board adopted, and the Company’s stockholders approved, the 2018 Equity Incentive Plan (the “2018 Plan”), which authorized the issuance of up to 1.4 million shares, subject to an annual 4% increase based on the number of shares of common stock outstanding, in the form of restricted stock, stock appreciation rights and stock options to the Company’s directors, employees and consultants. The amount and terms of grants were determined by the Board. All stock options granted to date have had exercise prices equal to the fair value, as determined by the closing price as reported by the Nasdaq Global Market, of the underlying common stock on the date of grant. As of June 30, 2026, there were no shares available for future issuance under the 2018 Plan because the share reserve under the 2018 Plan was decreased to the number of shares of common stock reserved for all outstanding awards under the 2018 Plan.

2020 Inducement Incentive Plan

In December 2020, the Board adopted the 2020 Inducement Incentive Plan (the “2020 Inducement Plan”), which authorized the issuance of up to 0.4 million shares in the form of stock options, stock appreciation rights, restricted stock awards, restricted stock unit awards, performance stock awards and other stock awards to eligible employees who satisfy the standards for inducement grants under Nasdaq Global Market rules. In March 2022, the Board approved an additional 0.5 million shares for issuance under the 2020 Inducement Plan. In October 2025, the Board approved an additional 0.6 million shares for issuance under the plan. An individual who previously served as an employee or director of the Company is not eligible to receive awards under the 2020 Inducement Plan other than following a bona fide period of non-employment. The amount and terms of grants are determined by the Board. As of June 30, 2026, there were 1.4 million shares available for future issuance under the 2020 Inducement Plan.

The Company recognized $0.7 million and $1.8 million in share-based compensation expense related to the restricted stock units and PRSUs for the three months ended June 30, 2026 and 2025, respectively and $2.4 million and $3.3 million for the six months ended June 30, 2026 and 2025, respectively. As of June 30, 2026, there was $8.0 million of unrecognized compensation cost related to non-vested restricted stock units and PRSUs, which the Company expects to recognize over a weighted average period of 2.3 years. The total fair

(Unaudited)

value at the vesting date of restricted stock units and PRSUs vested during the six months ended June 30, 2026 was $2.0 million.

The Company has granted PRSUs to certain key employees of the Company, with vesting subject to the recipient’s continued service with the Company through the applicable vesting date and the achievement of certain performance conditions as outlined in the award document. For legacy Greenbrook employees who became Neuronetics employees in connection with the Arrangement, the awards are subject to the terms of the 2020 Inducement Plan. For legacy Neuronetics employees, the awards are subject to the 2018 Plan.

The Company offers the Board the opportunity to defer restricted stock units into an equity-based deferred equity compensation plan known as the restricted stock unit deferral election plan (the “RSUDEP”). The Company offered certain employees the opportunity to defer into the RSUDEP restricted stock units with grant dates in 2024 and 2025, and discontinued employee eligibility beginning with restricted stock units with grant dates in 2026.

Benefits from these plans are payable in shares of Neuronetics stock and the awards under these plans are unfunded to the plans’ participants. Restricted stock units deferred under the RSUDEP are counted against the total shares available for future issuance under the 2018 Plan. As of June 30, 2026, there were 0.3 million shares deferred under the RSUDEP.

The Company did not grant PRSUs during the three and six months ended June 30, 2026.

18.     COMMITMENTS AND CONTINGENCIES

Executive Employment Agreements

The Company has entered into an employment agreement and offer letters with certain key executives, providing for compensation and severance in certain circumstances, as defined in the agreements.

Legal Matters

The Company is subject from time to time to various claims and legal actions arising during the ordinary course of its business. Management believes that there are currently no claims or legal actions that would reasonably be expected to have a material adverse effect on the Company’s results of operations, financial condition, or cash flows.

Other Matters

We are subject to various audits from government agencies including Medicaid and Medicare which involve the potential recoupment of reimbursements received from these agencies. These audits occur in the ordinary course of business. As of June 30, 2026 the Company had $0 of expenses recorded within other payables on the consolidated balance sheets. As of December 31, 2025, the Company had $0.8 million of expenses recorded within accrued expenses on the consolidated balance sheets.

19.     SEGMENT INFORMATION

The Company reports the results of its operations as two segments in its consolidated financial statements: (i) NeuroStar, formerly known as medical device and (ii) Greenbrook, formerly known as clinic services.

The determination of its reporting segments was made based on its strategic priorities, which corresponds to the way the Company’s chief operating decision maker (“CODM”) reviews and evaluates operating performance to make decisions about resources to be allocated. For our operating segments, the CODM

23

Table of Contents

NEURONETICS, INC.

Notes to Interim Consolidated Financial Statements

(Unaudited)

uses segment gross profit and segment loss before unallocated general and administrative as the primary measure of segment performance because it reflects results that are directly attributable to each reportable segment and is the measure most consistent with the Company’s consolidated results prepared in accordance with U.S. GAAP. The CODM does not regularly review any other measures of segment profit or loss for purposes of assessing segment performance or allocating resources.

On a monthly basis, the CODM considers month-to-month and budget-to-actual variances for both measures when allocating resources to segments. The accounting policies of its segment are the same as those described in the summary of significant accounting policies. The CODM is regularly provided information on total consolidated assets and liquidity; however, the CODM is not provided asset information at the reportable segment level. Accordingly, segment assets have not been disclosed.

Significant segment expenses regularly reviewed by the CODM for both segments include directly attributable cost of revenues, selling, general and administrative and research and development expenses. Unallocated general and administrative costs include corporate support functions such as executive management, corporate accounting, information technology, legal, human resources and Board fees. Additionally, unallocated general and administrative costs may include expenses such as litigation and merger and acquisition related costs, which are not specific to a segment and thus not allocated to the reportable segments.

Segment information for prior periods has been recast to conform to the current year reportable segment structure. There were no intercompany transactions between the Company’s reportable segments during the periods presented. Reportable segment information is presented below (in thousands):

20.     NONCONTROLLING INTEREST

The Company has operating agreements with several non-wholly owned entities. The non-controlling interest percentages range from 7% to 49%. The Company has control over these entities under U.S. GAAP as the Company has power over all significant decisions made by these entities. Thus, 100% of the financial results of these subsidiaries are included in the Company’s consolidated financial results.

21.     GOVERNMENT ASSISTANCE

Employee Retention Credit

The Coronavirus Aid, Relief and Economic Security Act provided an employee retention credit (the “ERC”), a refundable tax credit related to certain payroll taxes. The Company applied the grant model and determined that the criteria for recognition of the ERC were met based on its eligibility assessment and filing of the ERC claim.

During the six months ended June 30, 2025, Neuronetics received $2.6 million related to its ERC claim, consisting of $2.3 million of claims related to fiscal year 2021 and interest of $0.3 million.

During the six months ended June 30, 2026, Greenbrook received $2.2 million related to its ERC claim. On March 2, 2026, the Company entered into an agreement with Madryn Asset Management, LP and its affiliates (collectively, “Madryn”), pursuant to which it paid $1.1 million of the ERC proceeds to Madryn. The Company incurred $0.3 million of professional fees and recognized net other income of $0.8 million. This payment to Madryn related to the Term Loan and Exchange Agreement previously executed between Madryn and Greenbrook prior to the completion of the Arrangement. Madryn is the Company’s largest stockholder, and Avinash Amin, M.D., a representative of Madryn, serves on the Board.

Item 2.     Management’s Discussion and Analysis of Financial Condition and Results of Operations.

The following discussion and analysis of our financial condition and results of operations, as well as other sections in this Quarterly Report on Form 10-Q, should be read in conjunction with our unaudited interim consolidated financial statements and related notes thereto included elsewhere herein. In addition to historical financial information, some of the information contained in the following discussion and analysis contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”) and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). All statements other than statements of historical facts, including statements regarding our future results of operations and financial position, business strategy, current and prospective products, product approvals, research and development costs, current and prospective collaborations, timing and likelihood of success, plans and objectives of management for future operations and future results of current and anticipated products, are forward-looking statements. These statements involve known and unknown risks, uncertainties and other important factors that may cause our actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements.

In some cases, you can identify forward-looking statements by terms such as “may,” “will,” “would,” “should,” “expect,” “plan,” “design,” “anticipate,” “could,” “intend,” “target,” “project,” “contemplate,” “believe,” “estimate,” “predict,” “potential,” “outlook” or “continue” or the negative of these terms or other similar expressions. The forward-looking statements in this Quarterly Report on Form 10-Q are only predictions.

Overview

We believe that mental health is as important as physical health. The Company’s first commercial product, the System, is a non-invasive and non-systemic office-based treatment that uses 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 FDA to treat adult patients with 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 OCD and for adolescent patients aged 15-21 with MDD. It is

27

Table of Contents

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 Treatment Centers across the U.S., offering TMS therapy using the Systems. The Company acquired Greenbrook, a provider of mental healthcare services, pursuant to 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.

Effective as of December 9, 2024, Neuronetics and Greenbrook completed the Arrangement. Each share of Greenbrook common stock outstanding immediately prior to the effective time of the Arrangement was exchanged for shares of Neuronetics common stock at a specified exchange ratio upon closing of the Arrangement. We continue to operate as Neuronetics, Inc., and the Company’s shares trade on the NASDAQ Global Market under the ticker “STIM.”

We designed the System as a non-invasive therapeutic alternative to treat patients who suffer from MDD and to address many of the key limitations of existing treatment options. Additionally, through our acquisition of Greenbrook, we now derive revenue directly from our Treatment Centers, by providing TMS therapy and SPRAVATO® for MDD and other mental health disorders. We derive the majority of our revenues from Greenbrook revenue,treatment session sales, and sales of the System.

We currently operate in two segments: NeuroStar, formerly known as medical device and Greenbrook, formerly known as clinic services. We generate revenues from clinic operations, initial capital sales of our systems, sales of our recurring treatment sessions, service and repair, clinic collaboration services and extended warranty contracts.

For the three months ended June 30, 2026, our Greenbrook revenue and our NeuroStar revenue represented 65% and 35% of our revenues, respectively. For the six months ended June 30, 2026, Greenbrook revenue and our NeuroStar revenue represented 64%and 36% of our revenues, respectively.

Greenbrook revenue consists of revenue attributable to the performance of treatments to patients in the U.S. In circumstances where the net patient fees have not yet been received, the amount of revenue recognized is estimated based on an expected value approach. Due to the nature of the industry and complexity of our Greenbrook revenue arrangements, where price lists are subject to the discretion of payors, variable consideration exists that may result in price concessions and constraints to the transaction price for the services rendered.

Greenbrook revenue reimbursements are derived from third-party payors including federal and state agencies (under the federal healthcare programs), managed care health plans and commercial insurance companies.

We currently sell the System and recurring treatment sessions in the U.S. through our sales and customer support team. Our sales force targets an estimated 53,000 psychiatrists across 26,000 practices. We expect to continue to expand our direct sales and customer support team to further penetrate the market by demonstrating the benefits of the System to providers and their patients. Some of our customers have purchased or may purchase more than one of the Systems. Based on our commercial data, we believe many providers can recoup their initial capital investment in a System by providing a standard course of treatment to approximately 12 patients. We believe psychiatrists can generate approximately $9,000 of average revenue per patient for a standard course of treatment, which may provide meaningful incremental income to their practices. We serve a diverse customer base. In the U.S., providers are reimbursed by federal healthcare programs, as well as the vast majority of commercial payors, for treatment sessions utilizing our System.

Our research and development efforts are primarily focused on hardware and software product developments and enhancements of the System and clinical development relating to additional indications. We outsource the manufacture of components of the Systems that are produced to our specifications, and individual

28

Table of Contents

components are either shipped directly from our third-party contract manufacturers to our customers or consolidated into pallets at our Malvern, Pennsylvania facility prior to shipment. Final installation of these systems occurs at the customer site.

Total revenues increased by $3.5 million, or 9%, from $38.1 million for the three months ended June 30, 2025 to $41.6 million for the three months ended June 30, 2026 and increased by $5.9 million, or 8%, from $70.1 million for the six months ended June 30, 2025 to $76.0 million for the six months ended June 30, 2026. The increase was primarily attributable to an increase in Greenbrook revenue. We incurred net losses of $3.5 million and $14.2 million for the three and six months ended June 30, 2026, respectively compared to net losses of $9.8 million and $22.5 million for three and six months ended June 30, 2025, respectively. As of June 30, 2026, we had an accumulated deficit of $473.2 million.

Global Economic Conditions

We are continuing to closely monitor macroeconomic impacts, including but not limited to developments affecting financial institutions, supply chains, unemployment rates, investment values, consumer confidence, inflationary and potential recessionary pressures, on our business, results of operations and financial results, which could adversely affect us.

Components of Our Results of Operations

Revenues

We have generated revenues primarily from the sale of the Systems and related sales and rentals of the System, clinic revenue and the recurring revenues from our sale of treatment sessions in the U.S.

Greenbrook Revenues. Greenbrook revenue, formerly known as service or clinic revenue, consisting of TMS services, SPRAVATO® sales and other mental wellness services is determined based on net patient fees, which includes estimates for contractual allowances and discounts. Net patient fees are estimated using an expected value approach where management considers such variables as the average of previous net patient fees received by the applicable payor and fees received by other patients for similar services and the Company’s best estimate leveraging industry knowledge and expectations of third-party payors’ fee schedules. We expect clinic revenue to increase in 2026.

NeuroStar Revenues. NeuroStar revenue, formerly known as products and other revenue, consists of System revenues,treatment session revenues, and other revenues.

System Revenues. System revenues consist primarily of sales or rentals of a capital component, including equipment upgrades to the initial sale of the System. The Systems can be purchased outright or on a sales type lease basis by certain customers. Additionally, Systems may be sold as unlocked Systems, which do not require the customer to purchase treatment sessions for the life of the System.

Treatment Session Revenues. Treatment session revenues primarily include sales of treatment sessions and SenStar treatment links. The treatment sessions are access codes that are delivered electronically in the U.S. The SenStar treatment links are disposable units containing single-use access codes that are sold and used outside the U.S. Access codes are purchased separately by our customers, primarily on an as-needed basis, and are required by the System in order to deliver treatment sessions.

Other Revenues. Other revenues are derived primarily from service and repair, research collaboration agreements and extended warranty contracts with our existing customers.

Refer to the section titled “Critical Accounting Policies and Use of Estimates—Revenue Recognition” in our Annual Report on Form 10-K filed with the SEC on March 17, 2026. Also, refer to “Summary of Significant Accounting Policies” in Notes to Interim Consolidated Financial Statements located in Part I – FINANCIAL INFORMATION, Item 1. Financial Statements.

Cost of Revenues and Gross Margin

Cost of revenues consists of the costs of components and products purchased from our third-party contract manufacturers of the Systems. We use third-party contract manufacturing partners to produce the components for and assemble the Systems. Cost of revenues also includes costs related to personnel, warranty, shipping, amortization of capitalized software and our operations and field service departments. Our clinic costs primarily include direct center and patient care/treatment costs, regional employee compensation and depreciation. We expect our cost of revenues to increase mainly for Greenbrook, as our product mix changes.

Our gross profit is calculated by subtracting our cost of revenues from our revenues. We calculate our gross margin as our gross profit divided by our revenues. Our gross margin has been and will continue to be affected by a variety of factors, primarily product sales mix, pricing and third-party contract manufacturing costs. Our gross margins on revenues from sales of the Systems and Greenbrook revenue are lower than our gross margins on revenues from sales of treatment sessions and sale of unlocked systems. As a result, the sales mix between the Systems, Greenbrook revenues and treatment sessions can affect the gross margin in any reporting period.

Sales and Marketing Expenses

Sales and marketing expenses consist of commercial activities related to the sale of the Systems and clinic services and personnel costs including salaries and related benefits, sales commissions and share-based compensation for employees focused on these efforts. Other significant sales and marketing costs include conferences and trade shows, promotional and marketing activities, including direct and online marketing and practice support programs.

We anticipate that our sales and marketing expenses will decrease in 2026 relative to 2025 as a result of the cost efficiencies realized post-acquisition across the sales and marketing divisions.

General and Administrative Expenses

General and administrative expenses consist primarily of personnel expenses, including salaries and related benefits, share-based compensation and travel expenses, for employees in executive, finance, clinic support, information technology, legal and human resource functions. General and administrative expenses also include insurance, outside legal fees, accounting and other consulting services, audit fees from our independent registered public accounting firm, Board fees and other administrative costs, such as corporate facility costs, including rent, utilities, depreciation and maintenance not otherwise included in cost of revenues.

We anticipate that our general and administrative expenses will decrease during 2026 compared to 2025 expenses.

Research and Development Expenses

Research and development expenses consist primarily of personnel expenses, including salaries and related benefits and share-based compensation for employees in clinical development, product development, regulatory and quality assurance functions, as well as expenses associated with outsourced professional scientific development services and costs of investigative sites and consultants that conduct our preclinical and clinical development programs. We typically use our employee, consultant and infrastructure resources across our research and development programs.

We expect our research and development expenses to decrease during 2026 compared to 2025 expenses.

Interest Expense

Interest expense consists of cash interest payable under our credit facility and the amortization of deferred financing costs related to our indebtedness.

Other Income, Net

Other income, net, consists primarily of interest income earned on our money market account balances and notes receivable and ERC payments.

Loss on extinguishment of debt

Loss on debt extinguishment consists of prepayment penalties and impairment of deferred financing costs associated with the extinguishment of debt, as well as fees incurred with third parties in connection with debt extinguishment.

Revenues

Total revenue for the three months ended June 30, 2026 was $41.6 million, an increase of $3.5 million, or 9%, compared to the three months ended June 30, 2025 revenue of $38.1 million.

The increase in revenue was primarily driven by higher Greenbrook revenue, which increased $3.9 million, or 17%, to $26.9 million in the second quarter of 2026 from $23.0 million in the second quarter of 2025, reflecting continued contributions from clinics acquired in connection with the Greenbrook transaction and improved revenue cycle management within our Greenbrook segment. The growth was partially offset by a decline in NeuroStar revenue, which decreased $0.4 million to $14.7 million for the three months ended June 30, 2026 from $15.1 million for the three months ended June 30, 2025.

Cost of Revenues and Gross Margin

Cost of revenues remained relatively consistent at $20.3 million for the three months ended June 30, 2026, compared to $20.4 million for the three months ended June 30, 2025. Gross margin increased from 46.6% for the three months ended June 30, 2025 to 51.1% for the three months ended June 30, 2026. The increase in gross margin was primarily due to sales of unlocked capital systems, which carry a higher average selling price, as well as improved revenue cycle management within the Greenbrook clinics.

Sales and Marketing Expenses

Sales and marketing expenses decreased by $1.9 million, or 16.0%, from $11.9 million for the three months ended June 30, 2025 to $10.0 million for the three months ended June 30, 2026. The decrease was primarily driven by lower personnel costs and reduced marketing program spend.

General and Administrative Expenses

General and administrative expenses decreased by $0.8 million, or 6%, from $12.2 million for the three months ended June 30, 2025 to $11.4 million for the three months ended June 30, 2026. The decrease was due to a decrease in stock based expense within the general and administrative function.

Research and Development Expenses

Research and development expenses decreased by $0.5 million, or 26%, from $1.8 million for the three months ended June 30, 2025 to $1.3 million for the three months ended June 30, 2026. The decrease in research and development was driven by personnel expense.

Interest Expense

Interest expense increased by $0.1 million, or 8%, from $2.0 million for the three months ended June 30, 2025 to $2.1 million for the three months ended June 30, 2026, primarily due to a higher outstanding debt balance.

Other Income, Net

Other income, net decreased by $0.03 million, or 14%, primarily due to lower interest income earned on the Company's money market accounts and notes receivable.

Revenues

Total revenue for the six months ended June 30, 2026 was $76.0 million, an increase of 8% compared to the six months ended June 30, 2025 revenue of $70.1 million.

The increase in revenue was primarily driven by higher Greenbrook revenue, which increased $6.7 million, or 16%, to $48.4 million for the six months ended June 30, 2026 from $41.7 million for the six months ended June 30, 2025. The increase in Greenbrook revenue was primarily attributable to contributions from clinics acquired in connection with the Greenbrook transaction, as well as continued growth in clinic operations and improved revenue cycle management within the Greenbrook segment. This growth was partially offset by a decrease in NeuroStar revenue, which declined $0.8 million, or 3%, to $27.6 million for the six months ended June 30, 2026 from $28.4 million for the six months ended June 30, 2025. Greenbrook revenue represented 64% of total revenue for the six months ended June 30, 2026 compared to 59% for the six months ended June 30, 2025, while NeuroStar revenue represented 36% of total revenue compared to 41% in the prior-year period.

Cost of Revenues and Gross Margin

Cost of revenues increased by $2.0 million, or 6%, from $36.6 million for the six months ended June 30, 2025 to $38.6 million for the six months ended June 30, 2026. Gross margin increased from 47.8% for the six months ended June 30, 2025 to 49.2% for the six months ended June 30, 2026. The increase in gross margin

33

Table of Contents

was primarily due to sales of unlocked capital systems, which carry a higher average selling price, as well as improved revenue cycle management within the Greenbrook clinics.

Sales and Marketing Expenses

Sales and marketing expenses decreased by $3.2 million, or 13%, from $23.9 million for the six months ended June 30, 2025 to $20.7 million for the six months ended June 30, 2026. The decrease was primarily driven by lower personnel costs, reduced marketing program spend, and a favorable bad debt adjustment related to the current expected credit loss reserve.

General and Administrative Expenses

General and administrative expenses decreased by $0.8 million, or 3%, from $25.3 million for the six months ended June 30, 2025 to $24.5 million for the six months ended June 30, 2026. The decrease was due to a decrease in stock based expense within the general and administrative function.

Research and Development Expenses

Research and development expenses decreased by $0.7 million, or 21%, from $3.4 million for the six months ended June 30, 2025 to $2.7 million for the six months ended June 30, 2026. The decrease in research and development was primarily driven by lower personnel expense.

Interest Expense

Interest expense increased by $0.5 million, or 13%, from $3.9 million for the six months ended June 30, 2025 to $4.4 million for the six months ended June 30, 2026, primarily due to a higher outstanding debt balance.

Loss on extinguishment of debt

Loss on extinguishment of debt amounting to $0.5 million was recorded during the six months ended June 30, 2026, related to the Perceptive Facility. This included $0.3 million of early prepayment fees and $0.2 million of deferred financing expense related to extinguishment of debt.

Other Income, Net

Other income, net increased by $0.8 million, or 172%, from $0.4 million for the six months ended June 30, 2025 to $1.2 million for the six months ended June 30, 2026, primarily due to higher interest income earned on the Company's money market accounts, notes receivable and ERC payments.

Liquidity and Capital Resources

Overview

As of June 30, 2026, we had cash and cash equivalents of $19.2 million and an accumulated deficit of $473.2 million, compared to cash and cash equivalents of $28.1 million and an accumulated deficit of $458.8 million as of December 31, 2025. We incurred negative cash flows from operating activities of $10.4 million and $20.5 million for the six months ended June 30, 2026 and 2025, respectively. 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), and revenues from Greenbrook and NeuroStar. As of June 30, 2026, the Company had $65.0 million of borrowings outstanding under the Perceptive Facility, which has a final maturity on July 25, 2029. The Perceptive Facility is subject to certain financial covenants including a minimum net revenue covenant that escalates over the term of the Perceptive Facility and a minimum liquidity covenant.

34

Table of Contents

If our cash and cash equivalents and anticipated revenues from Greenbrook and NeuroStar are insufficient to satisfy our liquidity requirements, we may seek to sell additional common or preferred equity or debt securities or enter into a new credit facility or another form of third-party funding or seek other debt financing. If we raise additional funds by issuing equity or equity-linked securities, our stockholders would experience dilution and any new equity securities could have rights, preferences and privileges superior to those of holders of our common stock. Debt financing, if available, may involve covenants restricting our operations or our ability to incur additional debt. We cannot be assured that additional equity, equity-linked or debt financing will be available on terms favorable to us or our stockholders, or at all. It is also possible that we may allocate significant amounts of capital towards products or technologies for which market demand is lower than expected and, as a result, abandon such efforts. If we are unable to maintain our current financing or obtain adequate additional financing when we require it, or if we obtain financing on terms which are not favorable to us, or if we expend capital on products or technologies that are unsuccessful, our ability to continue to support our business growth and to respond to business challenges could be significantly limited, or we may be required to delay the development, commercialization and marketing of our products.

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 accordance with 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 facility 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 to increase collections, 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.

Our current and future funding requirements will depend on many factors, including:

our ability to achieve revenue growth and improve operating margins;
compliance with the terms and conditions, including covenants, set forth in our credit facility;
the cost of expanding our operations and offerings, including our sales and marketing efforts;
our ability to improve or maintain coverage and reimbursement arrangements with domestic third-party and government payors;
our rate of progress in establishing coverage and reimbursement arrangements from international commercial third-party and government payors;
our rate of progress in, and cost of the sales and marketing activities associated with, establishing adoption of our products and maintaining or improving our sales to our current customers;
the cost of research and development activities, including research and development relating to additional indications of neurohealth disorders;

the effect of competing technological and market developments;

Item 3.     Quantitative and Qualitative Disclosures About Market Risk.

Refer to the information described in “Item 7A. Quantitative and Qualitative Disclosures About Market Risk” section of the Company’s Annual Report on Form 10-K filed with the SEC on March 17, 2026. There have been no material changes to our market risk described therein.

We are continuing to closely monitor macroeconomic impacts, including but not limited to tariffs, developments affecting financial institutions, supply chains, unemployment rates, investment values, consumer confidence, inflationary and potential recessionary pressures, on our business, results of operations and financial results, which could adversely affect us. Although we do not believe inflation or tariffs have had a material impact on our financial condition, results of operations or cash flows to date, a high rate of inflation in the future may have an adverse effect on our ability to maintain and increase our gross margin or decrease our operating expenses as a percentage of our revenues if the selling prices of our products do not increase as much or more than our costs increase.

Evaluation of Disclosure Controls and Procedures

The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act, refers to controls and procedures that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure. As required by Rules 13a-15(b) and 15d-15(b) of the Exchange Act, our management, with the participation of our principal executive officer and principal financial and accounting officer, evaluated the effectiveness of our disclosure controls and procedures as of the end of the period covered by this Quarterly Report on Form 10-Q.
