Organization, Consolidation and Presentation of Financial Statements [Abstract]
The Company	The Company NeuroPace, Inc., or the Company, was incorporated in the state of Delaware on November 19, 1997. The Company is a medical device company that has developed the RNS System, the only commercially available brain-responsive neuromodulation system designed for treating drug-resistant focal epilepsy by delivering personalized, real-time treatment at the seizure source. The Company began commercializing its products in the United States in 2014. At-the-Market Equity Offering In November 2022, the Company filed a Registration Statement on Form S-3, or Shelf, with the Securities and Exchange Commission, or the SEC, in relation to the registration of common stock, preferred stock, debt securities, warrants or any combination thereof for up to an aggregate of $150.0 million, of which $50.0 million may be issued and sold pursuant to an at-the-market, or ATM, offering program for sales of the Company’s common stock under a sales agreement, or Sales Agreement, with Leerink Partners LLC, or Leerink (formerly SVB Securities LLC). The Company agreed to pay Leerink up to 3.0% of the gross proceeds of sales of common stock made through the Sales Agreement. The Company’s common stock would be sold at prevailing market prices at the time of the sale and, as a result, prices may vary. During the year ended December 31, 2024, the Company sold 444,555 shares of common stock under the Sales Agreement for gross proceeds of $3.4 million, or $3.2 million after deducting sales commissions and offering expenses. In January 2025, the Company sold 18,590 shares of common stock under the Sales Agreement for gross proceeds of $0.2 million, or $0.2 million after deducting sales commissions and offering expenses. In February 2025, the Company terminated the Sales Agreement and the ATM program. On the date of termination, the Company had $38.3 million remaining under the ATM program. Follow-On Offering In February 2025, the Company completed a follow-on offering of 7,475,000 shares of the Company’s common stock, including 975,000 shares from the exercise of the underwriters’ option to purchase additional shares, at an offering price of $10.00 per share. The aggregate net proceeds to the Company from the follow-on offering were $69.7 million after deducting underwriting discounts and commissions and offering expenses. The Company used $49.5 million of the net proceeds to repurchase all of the 5,270,845 shares held by its significant stockholder, KCK Ltd., at $9.40 per share. The repurchased shares became authorized but unissued shares. Liquidity and Capital Resources The Company has incurred operating losses and negative cash flows from operations since its inception and has an accumulated deficit of $549.7 million as of September 30, 2025. For the nine months ended September 30, 2025 and 2024, the Company used $11.5 million and $13.2 million, respectively, of cash in its operating activities. As of September 30, 2025, the Company had cash, cash equivalents and short-term investments of $60.0 million. Historically, the Company has funded its operations principally through the sales of its products, issuance of equity securities and debt financing. The Company’s condensed financial statements have been prepared on the basis of the Company continuing as a going concern for the next 12 months. Management believes that the Company’s cash, cash equivalents and short-term investments will allow the Company to continue its planned operations for at least the next 12 months from the date of the issuance of these unaudited interim condensed financial statements. The MidCap Credit Agreement (see Note 6) financial covenants require the Company to maintain an Applicable Liquidity Threshold no less than (a) $60.0 million until June 30, 2027, and (b) $40.0 million thereafter; or (c) provided the Company earns at least $90.0 million net revenue from the RNS System in 2026, liquidity shall be no less than $35.0 million thereafter. In the event liquidity falls below the Applicable Liquidity Threshold, the Company is required to achieve minimum annual trailing net RNS System revenue, tested on a quarterly basis, starting from $69.2 million over a trailing 12-month period ending June 30, 2025, and increasing to $87.3 million for the trailing 12-month period ending March 31, 2030. The Company’s trailing 12-month net RNS System revenue was $77.0 million as of September 30, 2025, exceeding the $70.1 million minimum per the MidCap Credit Agreement. In addition to the Applicable Liquidity Threshold, the MidCap Credit Agreement requires the Company to maintain a Minimum Liquidity balance of $25.0 million, which ceases to apply if the Company earns at least $90.0 million net revenue from RNS System in 2026. The MidCap Credit Agreement defines liquidity to include cash and cash equivalents, short-term investments, and following the initial borrowing under the Revolver (see Note 6), the available Revolver balance. If the Company does not meet the financial covenants, the lenders may call the debt, which will result in the Company immediately needing additional capital and may raise doubt about the Company’s ability to continue as a going concern. The Company’s ability to raise additional capital may be adversely impacted by global economic conditions and disruptions to, and volatility in, the financial markets in the United States and worldwide. If the Company is unable to raise capital when needed, it will need to delay, limit, reduce or terminate planned commercialization or product development activities in order to reduce costs. As of September 30, 2025, the Company was in compliance with all covenants of the MidCap Credit Agreement.
