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.) (“Solar” and such facility, the “Solar Facility”).

​

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, Tranche 2 Loan and 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 either the Tranche 1 Loan, Tranche 2 Loan or 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 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 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.

As of December 31, 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.

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 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, see “Note 26. Subsequent Events” for further discussion on the Perceptive Credit Agreement.

The Company was in compliance with the covenants under the Perceptive Facility at December 31, 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. The Solar Credit Facility had various amendments.

On March 7, 2024, the Company entered into a sixth amendment (the “Solar Sixth Amendment”) to the Solar Facility.

Under the Solar Sixth Amendment, Solar (i) waived the specified events with respect to the Company’s non-compliance with the required revenue under the net product revenue covenant and (ii) amended the financial covenants to reflect current projections.

As of June 30, 2024, the Company was not in compliance with its minimum net product revenue covenant under the Solar Facility. The amount of borrowing affected by this noncompliance was $60 million.

On July 25, 2024 following the Company’s entry into Perceptive Facility, 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.

A loss on extinguishment of debt amounting to $4.4 million was recorded during the three months ended September 30, 2024, related to the repayment of the Solar Facility. This included $1.2 million of early prepayment fees and $3.2 million of deferred financing expense related to extinguishment of debt. Additionally the Company incurred $2.8 million to Solar for exit fees in relation to the acquisition.
