1.&nbsp;&nbsp;&nbsp;&nbsp; DESCRIPTION OF BUSINESS

Neuronetics, Inc. (the "Company" or "Neuronetics" or the "Registrant") believes that mental health is as important as physical health. As a global leader in neuroscience, the Company is delivering more treatment options to patients and healthcare providers by offering exceptional in-office treatments that produce extraordinary results. The Company's first commercial product, the NeuroStar Advanced Therapy System, is a non-invasive and non-systemic office-based treatment that uses transcranial magnetic stimulation ("TMS"), to create a pulsed, magnetic resonance imaging ("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 United States ("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 NeuroStar Advanced Therapy System and associated treatment sessions to customers, we operate Greenbrook TMS Inc. ("Greenbrook") treatment centers ("Treatment Centers") across the U.S., offering NeuroStar Advanced Therapy. We acquired Greenbrook, a leading provider of mental healthcare services, pursuant to an Arrangement Agreement effective as of December 9, 2024. The NeuroStar Advanced Therapy System is safe, clinically effective, reproducible and precise and we believe is supported by the largest clinical data set of any competing TMS system. Treatment Centers also obtain 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 continue to trade on the Nasdaq Global Market under the ticker "STIM".

#### Liquidity
As of September 30, 2025, the Company had cash and cash equivalents of $28.0 million and an accumulated deficit of $451.6 million. The Company incurred negative cash flows from operating activities of $21.3 million for the nine months ended September 30, 2025 and $31.0 million for the year ended December 31, 2024. The Company has incurred operating losses since its inception, and management anticipates that our operating losses will lessen in the near term due to revenue growth and the pursuit of ongoing cost efficiencies in connection with our Greenbrook acquisition. The Company's primary sources of capital to date have been from its initial public offering ("IPO"), borrowings under its credit facility, proceeds from its secondary public offerings of common stock, and revenues from sales of its products. As of September 30, 2025, the Company had $70.0 million of borrowings outstanding under its credit facility, which mature 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 ("Canaccord"), 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 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 period ended September 30, 2025, the Company sold an aggregate of 2,261,835 shares of its common stock under the ATM Program at an average price of $3.68 per share, generating gross proceeds of

**Notes to Interim Consolidated Financial Statements**

**(Unaudited)**

approximately $8.3 million. The Company paid aggregate sales commissions of $0.3 million and incurred additional offering-related expenses of $0.2 million. As a result, net proceeds from the offering are $7.8 million.

As of September 30, 2025, the Company had approximately $41.7 million remaining available for future issuance under the ATM Program.

The Company's ability to meet its liquidity needs is dependent on growth in existing and acquired product lines and the realization of synergies subsequent to its acquisition of Greenbrook. Management believes that the Company's cash and cash equivalents as of September 30, 2025 and anticipated revenues from sales of our products and services are sufficient to fund the Company's operations for at least the next 12 months from the issuance of these consolidated financial statements.

2.&nbsp;&nbsp;&nbsp;&nbsp; BASIS OF PRESENTATION

The accompanying financial statements have been prepared in accordance with U.S. generally accepted accounting principles ("U.S. GAAP"). Any reference in these notes to applicable guidance is meant to refer to U.S. GAAP as found in the Accounting Standards Codification 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 Neuronetics and Greenbrook. 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 ("VOE") model. 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 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

[**Table of Contents**](#TOC)

**Notes to Interim Consolidated Financial Statements**

**(Unaudited)**

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. The unaudited interim consolidated statement of operations for the three and nine months ended September 30, 2025, and the consolidated statements of cash flows for the nine months ended September 30, 2025, 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 27, 2025, wherein a more complete discussion of significant accounting policies and certain other information can be found.

**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 require 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.&nbsp;&nbsp;&nbsp;&nbsp; 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 27, 2025.

4.&nbsp;&nbsp;&nbsp;&nbsp; RECENT ACCOUNTING PRONOUNCEMENTS

In November 2023, the FASB issued ASU 2023-07, *Improvements to Reportable Segment Disclosures* ("ASU 2023-07"), which requires public companies to disclose for each reportable segment the significant expense categories and amounts for such expenses. ASU 2023-07 is effective for annual periods beginning December 15, 2023, and for interim periods within fiscal years beginning after December 15, 2024. Accordingly, we have expanded our interim consolidated financial statement disclosures in order to comply with the guidance.

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

[**Table of Contents**](#TOC)

#### NEURONETICS, INC.
**Notes to Interim Consolidated Financial Statements**

**(Unaudited)**

effective for annual periods beginning after December 15, 2024. ASU 2023-09 will be effective for our annual period ended December 31, 2025. The Company is currently evaluating the impact of the adoption of ASU 2023-09 on its consolidated financial statements and related disclosures.

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 is currently evaluating the expected impact that the standard could have on its consolidated financial statements and related disclosures.

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.

5. ACQUISITION

Effective as of December 9, 2024, the Company completed the acquisition of Greenbrook whereby the Company acquired all of the issued and outstanding common shares of Greenbrook, which became a wholly owned subsidiary. The results of operations and financial position of Greenbrook are included in the Company's consolidated financial statements from the date of acquisition.

The allocation of the purchase price to the assets acquired and liabilities assumed was based on preliminary information and is subject to further adjustment within the measurement period.

In accordance with the acquisition method of accounting for a business combination, the purchase price of $38.8 million was allocated to the assets acquired and liabilities assumed based on their estimated fair values on the date of acquisition as follows (in thousands, except share data):

7.&nbsp;&nbsp;&nbsp;&nbsp; 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 September 30, 2025 and December 31, 2024 due to their short-term nature. The carrying values of the Perceptive Facility (as defined below) approximated its fair value as of September 30, 2025 and December 31, 2024 due to its variable interest rate.

The Perceptive First Amendment (as defined below) included contingently issuable warrants of up to 900,000 shares that did not meet equity classification. Accordingly, the Company classified the warrants as a liability

[**Table of Contents**](#TOC)

**Notes to Interim Consolidated Financial Statements**

**(Unaudited)**

at their fair value and will adjust the warrants to their fair value at each reporting period. At September 30, 2025, the fair value of the liability-classified warrants was de minimis.

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 September 30, 2025 and December 31, 2024 (in thousands):

**12.&nbsp;&nbsp;&nbsp;&nbsp; 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 42,000 square foot facility comprising office and warehouse space.

During the nine month period ended September 30, 2025, the Company executed a lease modification for this facility, extending the lease term through June 2033 for only 32,000 square feet of the premises.

The Company leases an approximately 9,600 square foot facility in Charlotte, North Carolina as a training facility for its NeuroStar Advanced Therapy 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.

Following the acquisition of Greenbrook, the Company has lease agreements related to its Treatment Centers and corporate offices. These lease agreements range from month-to-month to seven years in length.

Operating lease rent expense was $2.2 million and $0.2 million for the three months ended September 30, 2025 and 2024, respectively and $6.6 million and $0.6 million for the nine months ended September 30, 2025 and 2024, respectively. As of September 30, 2025, the weighted average remaining lease term of operating leases was 5.5 years, and the weighted average discount rate was 12.4%.

As of September 30, 2025 and December 31, 2024 the carrying amount of the lease receivables was $0.3 million. The Company does not have any unguaranteed residual assets.

*Lessor operating leases:*

NeuroStar Advanced Therapy Systems sold for which collection is not probable are accounted for as operating leases. For the three months ended September 30, 2025 and 2024, the Company recognized operating lease income of $0.06 million and $0.04 million, respectively. For the nine months ended September 30, 2025 and 2024, the Company recognized operating lease income of $0.2 million and $0.1 million, respectively.

The Company maintained rental equipment, net, of $0.1 million and $0.3 million as of September 30, 2025 and December 31, 2024, respectively, which are included in property and equipment, net on the consolidated balance sheets. Rental equipment depreciation expense was $0.01 million and $0.02 million for the three months ended September 30, 2025 and 2024, respectively and $0.05 million and $0.07 million for the nine months ended September 30, 2025 and 2024, respectively.

13.&nbsp;&nbsp;&nbsp;&nbsp; PREPAID COMMISSION EXPENSE

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

NeuroStar Advanced Therapy 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 represented by the current portion of prepaid commission expense, while the long-term portion is included in prepaid commission expense. Amortization expense was $0.8 million and $0.7 million for the three months ended September 30, 2025 and 2024, respectively, and $2.4 million and $2.1 million for the nine months ended September 30, 2025 and 2024, respectively.

15.&nbsp;&nbsp;&nbsp;&nbsp; REVENUE AND DEFERRED REVENUE

Contract terms typically require payment upon shipment or installation of the NeuroStar Advanced Therapy System and additional payments as access codes for treatment sessions are delivered, which can span several years after the NeuroStar Advanced Therapy 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.

As of September 30, 2025, the Company expects to recognize approximately the following percentages of deferred revenue by year:

---

| | |
|:---|:---|
| <br>**Year:** | **Revenue**<br>**Recognition** |
| Remainder of 2025 | 46% |
| 2026 | 54% |
| &nbsp;&nbsp;Total | 100% |

---

Revenue recognized for the three months ended September 30, 2025 and 2024 that was included in the contract liability balance at the beginning of the year was $0.1 million and $0.3 million, respectively. Revenue recognized for the nine months ended September 30, 2025 and 2024 that was included in the contract liability balance at the beginning of the year was $0.9 million and $1.4 million, respectively, and primarily represented revenue earned from separately priced extended warranties, customer deposits, milestone revenue, and clinical training.

*Customers*

Significant customers are those that represent more than 10% of the Company's total revenue. For the three months ended September 30, 2024, one customer accounted for 13% of the Company's revenue. For the nine months ended September 30, 2024, one customer accounted for 14% of the Company's revenue. Following the acquisition of Greenbrook, there are no significant customers for the three and nine months periods ended September 30, 2025.

*Perceptive Credit Facility*

On July 25, 2024, the Company entered into a Credit Agreement and Guaranty with Perceptive Credit Holdings 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.) ("Solar" and such facility, the "Solar Facility").

[**Table of Contents**](#TOC)

**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 is 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 has been no event of default under the Perceptive Facility prior to such election. The Tranche 2 Loan must be borrowed on or before January 31, 2026. Under the Tranche 3 Loan, the Company may request 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 is available until June 30, 2026. There are no scheduled repayments of the principal on the Tranche 1 Loan, the Tranche 2 Loan and 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 accrue 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% plus the greater of (a) 4.50% and (b) One-Month Term SOFR (as defined in the Perceptive Facility).

If the Company prepays either the Tranche 1 Loan, the Tranche 2 Loan or the Tranche 3 Loan prior to their scheduled 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 will be issued for 337,500 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 (the "Perceptive First Amendment") 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 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 million under Tranche 2, lowered the minimum liquidity balance requirement to $2 million through September 30, 2026, and issued Perceptive a warrant certificate exercisable into 225,000 shares of the Company's common stock.

As of September 30, 2025, the Company had $70.0 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 September 30, 2025.

#### Solar Credit Facility
On March 2, 2020, the Company entered into a Loan and Security Agreement with Solar as collateral agent and other lenders as defined in the Solar Facility.

In connection with the Company's entry into the Perceptive Facility, on July 25, 2024, the Company prepaid in full all outstanding obligations under, and terminated, the Solar Facility. In connection with this prepayment, the Company paid total consideration of $64.7 million, which consisted of (i) $60.0 million of remaining principal amount outstanding, (ii) $0.5 million of accrued and unpaid interest, (iii) $3.0 million in connection with the final payment fee, and (iv) $1.2 million in connection with the prepayment fee. The Company funded the prepayment of the Solar Facility using proceeds from the Perceptive Facility and cash on hand.

17.&nbsp;&nbsp;&nbsp;&nbsp; COMMON STOCK

#### Common Stock Offering
**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 approximately $18.9 million after deducting underwriting discounts, commissions and estimated offering expenses.**

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 nine months period ended September 30, 2025, the Company sold an aggregate of 2,261,835 shares of its common stock under the ATM Program at an average price of $3.68 per share, generating gross proceeds of approximately $8.3 million.

18.&nbsp;&nbsp;&nbsp;&nbsp; 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.

[**Table of Contents**](#TOC)

#### NEURONETICS, INC.
**Notes to Interim Consolidated Financial Statements**

**(Unaudited)**

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 the Company achieves profitability in the future, 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 units, 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.

The following potentially dilutive securities outstanding as of September 30, 2025 and 2024 have been excluded from the denominator of the diluted loss per share of common stock outstanding calculation (in thousands):

#### 2018 Equity Incentive Plan
In June 2018, the Company adopted 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. Effective as of December 9, 2024, the Company authorized the issuance of up to 5,592,670 shares under the 2018 Plan. The amount and terms of grants are determined by the Company's board of directors. 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. The contractual term of stock options is up to 10 years, and stock options are exercisable in cash or as otherwise determined by the Company's board of directors. Generally, stock options vest 25% upon the first anniversary of the date of grant and the remainder ratably monthly thereafter for 36 months. Restricted stock units generally vest ratably in three equal installments on the first, second, and third anniversaries of the grant date. PRSUs generally vest based on attainment of performance metrics, such as achievement of cash flow breakeven or retention of key employees as determined by the Company's board of directors. The fair value of the PRSUs based upon the achievement of certain share prices are determined using a risk neutral Monte Carlo simulation valuation model. As of September 30, 2025, there were 4.8 million shares available for future issuance under the 2018 Plan.

The Company recognized $1.4 million in share-based compensation expense related to the restricted stock units and PRSUs for the three months ended September 30, 2025 and 2024, and $4.7 million and $4.2 million for the nine months ended September 30, 2025 and 2024, respectively. As of September 30, 2025, there was $11.2 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 2.2 years. The total fair value at the vesting date of restricted stock units and PRSUs vested during the nine months ended September 30, 2025 was $4.6 million.

During the period ended September 30, 2025, the Company granted PRSUs to certain key employees, 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. The awards are subject to the 2018 Plan and the 2020 Plan.

The Company offers our board of directors and certain employees the opportunity to defer restricted stock units into an equity-based deferred equity compensation plan (the "RSUDEP"). Benefits from the RSUDEP are payable in shares of the Company's stock and the awards under the RSUDEP 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 September 30, 2025, there were 0.3 million shares deferred under this plan.

20.&nbsp;&nbsp;&nbsp;&nbsp; COMMITMENTS AND CONTINGENCIES

#### 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**

The Company is 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 and are in various stages of completion. As of September 30, 2025 and December 31, 2024, at this time, the Company has not recorded a liability related to any of these audits based on our best estimates of potential exposure known at this point in time.

On July 4, 2025, the "One Big Beautiful Bill Act" (the "OBBB Act") was enacted into law. The OBBB Act has multiple effective dates, with certain provisions effective in 2025 and others implemented through 2027. These changes include provisions allowing accelerated tax deductions for qualified property and research expenditures. We are in the process of evaluating the impact of the OBBB Act to our consolidated financial statements.

21.&nbsp;&nbsp;&nbsp;&nbsp; SEGMENT INFORMATION

Operating segments are defined as components of an enterprise about which separate discrete information is available for evaluation by the chief operating decision maker ("CODM") in deciding how to allocate resources and in assessing performance. The Company currently operates in one business segment focused on the sale and delivery of TMS products and clinical services that improve the quality of life for people suffering from neurohealth disorders. The CODM is the Company's chief executive officer.

**(Unaudited)**

The accounting policies of the Company's segment are the same as those described in the summary of significant accounting policies. The key measure of segment profit or loss that the CODM uses to allocate resources and assess performance is the Company's net loss from operations, as reported in the accompanying statements of operations. The measure of segment assets is reported on the balance sheets as total consolidated assets, with particular emphasis on the Company's available liquidity, including its cash and cash equivalents and restricted cash.

The following table illustrates information about reported segment revenue, measures of a segment's profit or loss, significant segment expenses, and measure of a segment's assets for the current reporting period.

22.&nbsp;&nbsp;&nbsp;&nbsp; NONCONTROLLING INTEREST

The Company has operating agreements with 22 non-wholly owned entities. The non-controlling interest percentages range from 10% 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.

There were no changes in the Company's non-wholly owned entities in the three and nine month periods ended September 30, 2025.

23.&nbsp;&nbsp;&nbsp;&nbsp; GOVERNMENT ASSISTANCE

*Employee Retention Credit*

#### Overview
We believe that mental health is as important as physical health. As a global leader in neuroscience, we are delivering more treatment options to patients and healthcare providers by offering exceptional in-office treatments that produce extraordinary results. Our first commercial product, the NeuroStar Advanced Therapy 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

[**Table of Contents**](#TOC)

associated with mood. The system is cleared by the FDA to treat adult patients with MDD that 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. The NeuroStar Advanced Therapy System is also available in other parts of the world. NeuroStar Advanced Therapy System is safe, clinically effective, reproducible and precise and we believe is supported by the largest clinical data set of any competing TMS system. We believe we are the market leader in TMS therapy based on over 229,429 global patients treated with over 8.2 million of our treatment sessions through September 30, 2025. We generated revenues of $37.3 million and $18.5 million for the three months ended September 30, 2025 and 2024, respectively, and $107.4 million and $52.4 million for the nine months ended September 30, 2025 and 2024, respectively.

We designed the NeuroStar Advanced Therapy 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 clinic revenue.

We generate revenues from clinic operations, initial capital sales of our systems, sales of our recurring treatment sessions and from service and repair and extended warranty contracts.

For the three months ended September 30, 2025, revenues from sales of our clinic revenue, treatment sessions and NeuroStar Advanced Therapy Systems represented 60%, 29% and 10% of our U.S. revenues, respectively. For the nine months ended September 30, 2025, revenues from sales of our clinic revenue, treatment sessions and NeuroStar Advanced Therapy Systems represented 60%, 30% and 9% of our U.S. revenues, respectively.

Clinic revenue consists of revenue attributable to the performance of treatments to patients in 15 states 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 clinic 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.

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

We currently sell our NeuroStar Advanced Therapy 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 our NeuroStar Advanced Therapy System to psychiatrists and their MDD patients. Some of our customers have purchased or may purchase more than one NeuroStar Advanced Therapy System. Based on our commercial data, we believe psychiatrists can recoup their initial capital investment in our system by providing a standard course of treatment to approximately 12 patients. We believe psychiatrists can generate approximately $8,500 of average revenue per patient for a standard course of treatment, which may provide meaningful incremental income to their practices. We have a diverse customer base of psychiatrists in group psychiatric practices in the U.S. Patients are reimbursed by federal healthcare programs and the vast majority of commercial payors in the U.S. for treatment sessions utilizing our NeuroStar Advanced Therapy System. For the three months ended September 30, 2024, one customer, Greenbrook, accounted for 13% of the Company's revenue. Following the acquisition of Greenbrook, there are no significant customers.

We market our products in a few select markets outside the U.S. through independent distributors. International revenues represented 3% of our total revenues for each of the three months ended September 30, 2025 and 2024 and 2% and 3% for the nine months ended September 30, 2025 and 2024, respectively. We expect our international revenues to decrease as a percentage of our total revenue.

[**Table of Contents**](#TOC)

Our research and development efforts are focused on the following: hardware and software product developments and enhancements of our NeuroStar Advanced Therapy System and clinical development relating to additional indications. We outsource the manufacture of components of our NeuroStar Advanced Therapy Systems that are produced to our specifications, and individual 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 our NeuroStar Advanced Therapy Systems occurs at the customer site.

Total revenues increased by $18.8 million, or 101%, from $18.5 million for the three months ended September 30, 2024 to $37.3 million for the three months ended September 30, 2025 and increased by $55.0 million, or 105%, from $52.4 million for the nine months ended September 30, 2024 to $107.4 million for the nine months ended September 30, 2025. The increase was primarily attributable to an increase in clinic revenue.

We incurred net losses of $9.4 million and $31.9 million for the three and nine months ended September 30, 2025 compared to net losses of $13.3 million and $31.0 million for three and nine months ended September 30, 2024. As of September 30, 2025, we had an accumulated deficit of $451.6 million.

**Global Economic Conditions**

We continue to closely monitor macroeconomic impacts, including, but not limited to, developments affecting financial institutions, supply chains, trade and tariff policy, 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 our NeuroStar Advanced Therapy Systems and related sales and rentals of the NeuroStar Advanced Therapy System, clinic revenue and the recurring revenues from our sale of treatment sessions in the U.S.

***Clinic Revenues.*** Clinic revenue 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 2025.

***NeuroStar Advanced Therapy System Revenues***. NeuroStar Advanced Therapy System revenues consist primarily of sales or rentals of a capital component, including equipment upgrades to the initial sale of the NeuroStar Advanced Therapy System. NeuroStar Advanced Therapy Systems can be purchased outright or on a rent-to-own basis by certain customers.

***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 NeuroStar Advanced Therapy 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 27, 2025. Also, refer to "Summary of Significant

[**Table of Contents**](#TOC)

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 primarily consists of the costs of components and products purchased from our third-party contract manufacturers of our NeuroStar Advanced Therapy Systems as well as the cost of treatment packs for individual treatment sessions. We use third-party contract manufacturing partners to produce the components for and assemble the completed NeuroStar Advanced Therapy Systems. Cost of revenues also includes costs related to personnel, royalties, warranty, shipping, amortization of capitalized software and our operations and field service departments. Our treatment center costs include direct center and patient care costs, regional employee compensation and depreciation. We expect our cost of revenues to increase mainly for Treatment Centers, 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 NeuroStar Advanced Therapy Systems and clinic revenue are lower than our gross margins on revenues from sales of treatment sessions and, as a result, the sales mix between NeuroStar Advanced Therapy Systems, clinic revenues and treatment sessions can affect the gross margin in any reporting period.

*Sales and Marketing Expenses*

Sales and marketing expenses consist of market research and commercial activities related to the sale of our NeuroStar Advanced Therapy Systems and treatment sessions 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, practice support programs, primarily digital media campaigns, travel and training expenses.

We anticipate that our sales and marketing expenses will increase in 2025 relative to 2024 as a result of the addition of the Greenbrook sales and marketing related expenses.

*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, information technology, legal, compliance and human resource functions. General and administrative expenses also include the cost of insurance, outside legal fees, accounting and other consulting services, audit fees from our independent registered public accounting firm, board of directors 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 increase in 2025 from 2024 due to an increase in the overall size of the general and administrative function within the consolidated company.

*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.

[**Table of Contents**](#TOC)

We expect our research and development expenses to decrease during 2025 compared to our 2024 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.

*Revenues*

Total revenue for the three months ended September 30, 2025 was $37.3 million, an increase of 101% compared to the three months ended September 30, 2024 revenue of $18.5 million. During the quarter, total U.S. revenue increased by 102% and international revenue increased by 73% compared to the prior year period.

The revenue growth was primarily due to the inclusion of clinic revenue of $21.8 million as a result of the acquisition of Greenbrook, partially offset by the absence of sales to Greenbrook of $2.4 million and a $0.6 million decline in sales of NeuroStar Advanced Therapy Systems and treatment session revenue to customers other than Greenbrook.

U.S. NeuroStar Advanced Therapy System revenue for the three months ended September 30, 2025 was $3.5 million, a decrease of 15% compared to the three months ended September 30, 2024 revenue of $4.1 million. For the three months ended September 30, 2025 and 2024, the Company sold 40 and 48 systems, respectively, that were recognized as NeuroStar Advanced Therapy System capital revenue during each period.

U.S. treatment session revenue for the three months ended September 30, 2025 was $10.5 million, a decrease of 21% compared to the three months ended September 30, 2024 revenue of $13.3 million. The decline was primarily attributable to the absence of $2.2 million in treatment session revenue to Greenbrook associated with the prior year period, as well as a further decrease in treatment session volume with other customers compared to the prior year period.

*Cost of Revenues and Gross Margin*

Cost of revenues increased by $15.7 million, or 346%, from $4.5 million for the three months ended September 30, 2024 to $20.2 million for the three months ended September 30, 2025. Gross margin decreased from 75.6% for the three months ended September 30, 2024 to 45.9% for the three months ended September 30, 2025. The decrease in gross margin was primarily a result of the inclusion of Greenbrook's clinic business and reduction in treatment session revenue.

*Sales and Marketing Expenses*

Sales and marketing expenses decreased marginally from $11.9 million for the three months ended September 30, 2024 to $11.8 million for the three months ended September 30, 2025. Sales and marketing expense increased during the period due to the inclusion of Greenbrook, which was offset by the decrease in bad debt expense during the same period.

[**Table of Contents**](#TOC)

*General and Administrative Expenses*

General and administrative expenses increased by $3.6 million, or 49%, from $7.4 million for the three months ended September 30, 2024 to $11 million for the three months ended September 30, 2025. The increase was primarily driven by the addition of Greenbrook general and administrative expenses of $6.1 million, partially offset by cost synergies realized following the acquisition of Greenbrook.

*Research and Development Expenses*

Research and development expenses decreased by $0.9 million, or 38%, from $2.4 million for the three months ended September 30, 2024 to $1.5 million for the three months ended September 30, 2025. The decrease in research and development was driven by personnel expense savings related to restructuring after the Company's acquisition of Greenbrook.

*Interest Expense*

Interest expense increased by $0.5 million, or 28% from $1.7 million for the three months ended September 30, 2024 to $2.2 million for the three months ended September 30, 2025, primarily due to a higher outstanding debt balance.

*Loss on extinguishment of debt*

Loss on extinguishment of debt amounting to $4.4 million was recorded during the three months ended September 30, 2024, related to the Solar Facility. This included $1.2 million of early prepayment fees and $3.2 million of deferred financing expense relates to extinguishment of debt.

*Other Income, Net*

Other income, net decreased by $0.4 million, or 77%, from $0.5 million for the three months ended September 30, 2024 to $0.1 million for the three months ended September 30, 2025, primarily as a result of decreased interest income earned on the Company's money market accounts and notes receivable interest.

*Revenues*

Total revenue for the nine months ended September 30, 2025 was $107.4 million, an increase of 105% compared to the nine months ended September 30, 2024 revenue of $52.4 million. During the nine months ended September 30, 2025, total U.S. revenue increased by 107% and international revenue increased by 28%.

The revenue growth was primarily due to the inclusion of clinic revenue of $63.5 million as a result of the acquisition of Greenbrook, partially offset by the absence of sales to Greenbrook of $7.6 million and a $0.9 million decline in sales of NeuroStar Advanced Therapy Systems and treatment session revenue to customers other than Greenbrook.

U.S. NeuroStar Advanced Therapy System revenue for the nine months ended September 30, 2025 was $9.8 million, a decrease of 14% compared to the nine months ended September 30, 2024 revenue of $11.4 million. For the nine months ended September 30, 2025 and 2024, the Company sold 112 and 137 systems, respectively, that were recognized as NeuroStar Advanced Therapy System capital revenue during each period. Additionally, for the nine months ended September 30, 2024 the Company executed 1 operating lease agreement which contributed to operating lease revenue. While the number of systems decreased, the average selling price per system increased by 5%.

U.S. treatment session revenue for the nine months ended September 30, 2025 was $30.9 million, a decrease of 19% compared to the nine months ended September 30, 2024 revenue of $38.0 million. The decline was primarily attributable to the absence of $7.1 million in treatment session revenue to Greenbrook associated with the prior year period.

*Cost of Revenues and Gross Margin*

Cost of revenues increased by $43.6 million, or 332%, from $13.1 million for the nine months ended September 30, 2024 to $56.7 million for the nine months ended September 30, 2025. Gross margin decreased from 74.9% for the nine months ended September 30, 2024 to 47.1% for the nine months ended September 30, 2025. The decrease in gross margin was primarily a result of the inclusion of Greenbrook's clinic business and reduction in treatment session revenue.

*General and Administrative Expenses*

General and administrative expenses increased by $16.8 million, or 86% from $19.5 million for the nine months ended September 30, 2024 to $36.3 million for the nine months ended September 30, 2025. The increase was primarily driven by the addition of Greenbrook general and administrative expense of $18.8 million, partially offset by cost synergies realized following the acquisition of Greenbrook.

*Research and Development Expenses*

Research and development expenses decreased by $2.1 million, or 30%, from $7.0 million for the nine months ended September 30, 2024 to $4.9 million for the nine months ended September 30, 2025.

Interest expense increased by $0.6 million, or 10%, from $5.5 million for the nine months ended September 30, 2024 to $6.1 million for the nine months ended September 30, 2025, primarily due to a higher outstanding debt balance.

*Loss on extinguishment of debt*

Loss on extinguishment of debt amounting to $4.4 million was recorded during the nine months ended September 30, 2024, related to the Solar Facility. This included $1.2 million of early prepayment fees and $3.2 million of deferred financing expense relates to extinguishment of debt.

*Other Income, Net*

Other income, net decreased by $1.4 million from $2.0 million for the nine months ended September 30, 2024 to $0.6 million for the nine months ended September 30, 2025, primarily as a result of decreased interest income earned on the Company's money market accounts and notes receivable interest.

#### Liquidity and Capital Resources
*Overview*

As of September 30, 2025, we had cash and cash equivalents of $28.0 million and an accumulated deficit of $451.6 million, compared to cash and cash equivalents of $18.5 million and an accumulated deficit of $419.8 million as of December 31, 2024. We incurred negative cash flows from operating activities of $21.3 million and $22.4 million for the nine months ended September 30, 2025 and 2024, respectively. We have incurred operating losses since our inception, and we anticipate that our operating losses will lessen in the near term due to revenue growth and the pursuit of ongoing cost efficiencies in connection with our Greenbrook acquisition. The Company's primary sources of capital to date have been proceeds from its IPO, borrowings under its credit facility, proceeds from its secondary public offerings and ATM offerings of common stock and revenues from sales of its products. As of September 30, 2025, the Company had $70.0 million of borrowings outstanding under the Perceptive Facility, which have 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.

[**Table of Contents**](#TOC)

If our cash and cash equivalents and anticipated revenues from sales or our products and services 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.

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 the Perceptive 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 and international third-party and government payors, particularly in Japan;

● 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;

● efficiency of our clinic operations; and

● the potential cost of and delays in product development as a result of any regulatory oversight applicable to our products.

The Company's material cash requirements include the following contractual and other obligations.

*Debt*

On July 25, 2024 the Company entered into the Perceptive Facility and used the proceeds to partially prepay in full all outstanding obligations under the Solar Facility. In connection with this prepayment, the Company paid Solar $64.7 million, which consisted of (i) $60.0 million of remaining principal amount outstanding, (ii) $0.5 million of accrued and unpaid interest, (iii) $3.0 million in connection with the final payment fee, and (iv) $1.2 million in connection with the prepayment fee. The Company funded the prepayment of the Solar Facility using proceeds from the Perceptive Facility and cash on hand.

[**Table of Contents**](#TOC)

In connection with the Perceptive Facility and closure of the Solar Facility, the Company recorded a loss on extinguishment of $4.4 million. This included $1.2 million of early prepayment fees and $3.2 million of deferred financing expense related to extinguishment of debt.

As of September 30, 2025, the Company had $70 million of borrowings outstanding under the Perceptive Facility, which has a final maturity on July 25, 2029. The interest rate on borrowings under the Perceptive Facility is the monthly SOFR (as defined in the Perceptive Facility) rate plus 7%.

*Leases*

The Company has lease arrangements for equipment and certain facilities, including corporate headquarters and our warehouse in Malvern, Pennsylvania and a training facility in Charlotte, North Carolina. Additionally following the acquisition of Greenbrook, the Company has lease agreements related to Treatment Centers. These lease agreements range from "month-to-month" to seven years in length. As of September 30, 2025, the Company had fixed lease payment obligations of $34.9 million, including $7.9 million due within the next twelve months.

---

*Net Cash used in Operating Activities*

Net cash used in operating activities for the nine months ended September 30, 2025 was $21.3 million, consisting primarily of a net loss of $31.9 million offset by a decrease in net operating assets of $1.9 million, and by non-cash charges of $8.7 million primarily consisting of depreciation and amortization and share-based compensation. The decrease in net operating assets was primarily due to decreases in accounts receivable, and decreases in accounts payable, accrued expenses, prepaid expenses and other assets and prepaid commission expense.

[**Table of Contents**](#TOC)

Net cash used in operating activities for the nine months ended September 30, 2024 was $22.4 million, consisting primarily of a net loss of $31.0 million and an increase in net operating assets of $4.6 million, offset by non-cash charges of $8.8 million and a loss on extinguishment of debt of $4.4 million. The increase in net operating assets was primarily due to decreases in accrued expenses related to the final payment fee to Solar, payment of our 2024 bonus accrued as of December 31, 2023, and increases in our accounts receivable offset by lower inventory levels from the prior year. Non-cash charges primarily consisted of depreciation and amortization, loss on extinguishment related to the Solar Facility, allowance for credit losses, and share-based compensation.

*Net Cash used in Investing Activities* 

Net cash used in investing activities for the nine months ended September 30, 2025 was $0.6 million, which was attributable to purchases of property and equipment and capitalized software costs.

Net cash used in investing activities for the nine months ended September 30, 2024 was $0.04 million, which was attributable to purchases of property and equipment and capitalized software costs, partially offset by the repayment of notes receivable.

*Net Cash provided by (used in) Financing Activities*

Net cash provided by financing activities for the nine months ended September 30, 2025 was $36.9 million. This primarily reflected proceeds from the issuance of common stock of $20.7 million and proceeds from the issuance of long-term debt of $10.0 million. In addition, the Company received approximately $8.3 million in proceeds from the issuance of common stock under the ATM Program. These inflows were partially offset by common stock offering issuance costs of $1.7 million, payments of issuance costs under the ATM Program of $0.3 million, and debt issuance costs of $0.1 million.

Net cash used in financing activities for the nine months ended September 30, 2024 was $16.4 million and primarily consisted of the repayment of the Solar Facility, proceeds from the Perceptive Facility, and payment of debt issuance costs related to the Perceptive Facility.
