NeuroPace, Inc., or the Company, was incorporated in the state of Delaware on November 19, 1997. The Company is a commercial-stage medical device company that has developed the RNS System, the only commercially available brain-responsive neuromodulation system designed for treating medically refractory focal epilepsy by delivering personalized, real-time treatment at the seizure source. The Company began commercializing its products in the United States in 2014.

On April 21, 2021, the Company’s registration statement on Form S-1 (File No. 333-254663) relating to its initial public offering, or IPO, of common stock became effective. The IPO closed on April 26, 2021, at which time the Company issued 6,900,000 shares of its common stock at a price of $17.00 per share, which included the issuance of shares in connection with the exercise by the underwriters of their option to purchase up to 900,000 additional shares. The Company received an aggregate of $117.3 million in gross proceeds, before underwriting discounts and commissions and offering costs, and approximately $105.5 million in net proceeds after deducting $8.2 million in underwriting discounts and commissions and $3.6 million in offering costs.

Upon the closing of the IPO, all outstanding shares of the Company’s redeemable convertible preferred stock converted into 16,614,178 shares of common stock, warrants to purchase 346,823 shares of Series B’ convertible preferred stock net exercised to 213,941 shares of Series B’ convertible preferred stock and subsequently converted into common stock on a one-to-one basis, and warrants to purchase 219 shares of common stock net exercised to 185 shares of common stock. In connection with the completion of its IPO, on April 26, 2021, the Company’s certificate of incorporation was amended and restated to provide for 200,000,000 authorized shares of common stock with a par value of $0.001 per share and 10,000,000 authorized shares of preferred stock with a par value of $0.001 per share.

The COVID-19 pandemic is affecting business conditions in the industry in which the Company operates. Beginning in March 2020, the Company’s net sales were negatively impacted by the COVID-19 pandemic as hospitals delayed or canceled elective procedures. In response to the pandemic, many state and local governments in the U.S. issued orders that temporarily precluded elective procedures in order to conserve scarce health system resources. The decrease in hospital admission rates and elective surgeries reduced both the number of patients being evaluated for treatment with and demand for elective procedures using the Company's RNS System. The Company has taken necessary precautions to safeguard its employees, patients, customers, and other stakeholders from theA similar

The unaudited interim condensed financial statements have been prepared in conformity with generally accepted accounting principles in the United States, or GAAP, as defined by the Financial Accounting Standards Board, or the FASB.

On August 18, 2020, the Company effected a 1-for-100 reverse stock split of its common stock and redeemable convertible preferred stock. The par value of the authorized stock was not adjusted as a result of the reverse stock split.

On April 9, 2021, the Company effected a 1-for-2.6 reverse stock split of its common stock and redeemable convertible preferred stock. The par value of the authorized stock was not adjusted as a result of the reverse stock split.

All issued and outstanding shares of common stock and redeemable convertible preferred stock and related per share amounts contained in the accompanying financial statements have been retroactively revised to reflect the combined effect of these reverse stock splits for all periods presented.

The condensed balance sheet as of December 31, 2020 was derived from the Company’s audited financial statements, but does not include all disclosures required by GAAP. The accompanying unaudited condensed financial statements as of JuneSeptember 30, 2021 and for the three and sixnine months ended JuneSeptember 30, 2021 and 2020, have been prepared by the Company, pursuant to the rules and regulations of the Securities and Exchange Commission, or the SEC, for interim financial statements. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. However, the Company believes that the disclosures are adequate to make the information presented not misleading. Accordingly, these financial statements should be read in conjunction with the audited financial statements as of and for the year ended December 31, 2020 and notes thereto, included in the Company’s final prospectus for the IPO filed with the SEC pursuant to Rule 424(b)(4) on April 23, 2021, or the final prospectus. In the opinion of management, all adjustments, consisting only of normal recurring adjustments necessary for a fair statement of the Company’s condensed financial position as of JuneSeptember 30, 2021 and condensed results of operations for the three and sixnine months ended JuneSeptember 30, 2021 and 2020 and condensed cash flows for the sixnine months ended JuneSeptember 30, 2021 and 2020 have been made. The results of operations for the three and sixnine months ended JuneSeptember 30, 2021 are not necessarily indicative of the results of operations that may be expected for the year ending December 31, 2021.

The preparation of unaudited interim condensed financial statements in conformity with GAAP requires the Company to make estimates and assumptions that affect the amounts and disclosures reported in the financial statements. The Company uses significant judgment when making estimates related to the valuation of its common stock and related stock-based compensation, the valuation of deferred tax assets and related valuation allowances, provision for excess and obsolete inventories, the valuation of derivative financial instruments and redeemable

Carrying amounts of certain of the Company’s financial instruments, including cash equivalents, accounts receivable, accounts payable and accrued liabilities, approximate fair value because of the short-term nature of these instruments. Short-term investments comprise available-for-sale debt securities, which are carried at fair value. The Company believes that its borrowings bear interest at the prevailing market rates for instruments with similar characteristics; accordingly, the carrying value of this instrument approximates its fair value. Derivative instruments and the redeemable convertible preferred stock warrant liability are carried at fair value based on unobservable market inputs. The Company determines the fair value of financial and non-financial assets and liabilities using the fair value hierarchy which establishes three levels of inputs that may be used to measure fair value (see Note 3).

Financial instruments that potentially subject the Company to credit risk consist of cash and cash equivalents, short-term investments and accounts receivable to the extent of the amounts recorded on the balance sheet. The Company’s cash is invested in one major financial institution in the United States. Deposits in this financial institution may exceed federally insured limits. The Company’s cash equivalents are invested in money market funds.

The Company’s accounts receivable are due from a variety of health care organizations in the United States. For the three and sixnine months ended JuneSeptember 30, 2021 and 2020, there were no customers that represented 10% or more of revenue. As of JuneSeptember 30, 2021 and December 31, 2020, no customer represented 10% or more of the Company’s accounts receivable.

The Company is subject to certain risks, including that its devices may not be approved or cleared or continue to be approved or cleared for marketing by governmental authorities or be successfully marketed for expanded indications. There can be no assurance that the Company’s products will achieve widespread adoption in the marketplace, nor can there be any assurance that existing devices or any future devices can be developed or manufactured at an acceptable cost and speed and with appropriate performance characteristics. The Company is also subject to risks common to companies in the medical device industry, including, but not limited to, new technological innovations, dependence on healthcare providers to prescribe initial implants and replacements, dependence upon third-party payors to provide adequate coverage and reimbursement, dependence on key personnel, single-source suppliers and vendors in connection with the manufacture of its products, concentration of Level 4 CECs and epileptologists, obtaining, maintaining, protecting, enforcing, and defending intellectual property rights and proprietary technology, product liability claims, legal proceedings, and compliance with government regulations.

The Company’s medical devices require approvals or clearances from the U.S. Food and Drug Administration, or the FDA, or international regulatory agencies. In addition, in order to continue the Company’s operations, compliance with various federal and state laws is required. If approvals or clearances were withdrawn by the FDA for the Company’s current products or if such approvals or clearances were denied or delayed for future products, product updates, or expanded indications for use, it would have a material adverse impact on the Company.

The Company capitalizes, within other assets, certain legal, accounting and other third-party fees that are directly related to the Company’s in-process equity financings, including its IPO, until such financings are consummated. After consummation of the equity financing, these costs are recorded as a reduction of the proceeds received as a result of the offering. Should a planned equity financing be abandoned, terminated or significantly delayed, the deferred offering costs are immediately written off to operating expenses. As of December 31, 2020, $0.5

Basic net loss per common share is calculated by dividing the net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period, without consideration of potentially dilutive securities. Diluted net loss per share is computed by dividing the net loss attributable to common stockholders by the weighted-average number of shares of common stock and potentially dilutive securities outstanding for the period. For purposes of the diluted net loss per share calculation, redeemable convertible preferred stock, stock options, common stock subject to repurchase related to early exercise of stock options, and convertible notes are considered to be potentially dilutive securities. Basic and diluted net loss attributable to common stockholders per share is presented in conformity with the two-class method required for participating securities, as the redeemable convertible preferred stock is considered a participating security because it participates in dividends with common stock. The Company also considers the shares issued upon the early exercise of stock options subject to repurchase to be participating securities, because holders of such shares have non-forfeitable dividend rights in the event a dividend is paid on common stock. The holders of redeemable convertible preferred stock and the holders of the shares issued upon early exercise of stock options subject to repurchase do not have a contractual obligation to share in the Company’s losses. As such, the net loss was attributed entirely to common stockholders. Because the Company has reported a net loss for all periods presented, diluted net loss per common share is the same as basic net loss per common share for those periods.

The Company measures certain financial assets and liabilities at fair value on a recurring basis. Fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be

The following table sets forth a summary of the changes in the fair value of the Company’s Level 3 financial instruments (in thousands):

The fair value of the derivative instrument has been estimated at the date of inception and at the subsequent balance sheet date using a two-step approach to valuation, employing a probability-weighted scenario valuation method and then comparing the instrument’s value with-and-without the derivative features in order to estimate their combined fair value, using unobservable inputs, which are classified as Level 3 within the fair value hierarchy.

In August 2020, the derivative instrument was extinguished in connection with the issuance of Series B’ redeemable convertible preferred stock and conversion of all outstanding convertible notes and accrued unpaid interest into shares of Series B’ redeemable convertible preferred stock.

In determining the fair value of the redeemable convertible preferred stock warrant liability, the Company used the Black-Scholes option pricing model to estimate the fair value using unobservable inputs including the expected term, expected volatility, risk-free interest rate and dividend yield (see Note 8). There were no warrants outstanding for the purchase of redeemable convertible preferred stock as of JuneSeptember 30, 2021, as all such warrants were net exercised to shares of common stock upon the closing of the IPO.

Inventories consist of the following (in thousands):

Depreciation expense for the three months ended JuneSeptember 30, 2021 and 2020 was $0.1 million and $0.1 million, respectively. Depreciation expense for the sixnine months ended JuneSeptember 30, 2021 and 2020 was $0.1$0.2 million and $0.2 million, respectively.

Accrued liabilities consist of the following (in thousands):

In August 2011, the Company entered into a non-cancelable operating lease for combined office and manufacturing facilities in Mountain View, California. The lease was scheduled to expire in April 2019 and was amended in May 2018 to extend it through June 2024. The terms of the facility lease provide for rental payments on

Rental payments range from $2.9 million to $3.3 million per year over the extended term of the lease. In April 2020, the Company amended the lease agreement to defer 50.0% of the rental payment for May and June 2020 of $0.3 million. The deferred rental payments accrued interest at an annual rate of 8.0% starting from October 1, 2020 and were paid in three equal monthly installments commencing on April 1, 2021.

Rent expense for the three months ended JuneSeptember 30, 2021 and 2020 was $0.7 million and $0.7 million, respectively. Rent expense for the sixnine months ended JuneSeptember 30, 2021 and 2020 was $1.4$2.1 million and $1.3$2.0 million, respectively. As of JuneSeptember 30, 2021 and December 31, 2020, $1.5$1.4 million and $2.0 million was recorded as deferred rent expense, respectively.

The Company’s future payments under the non-cancellable operating lease (in thousands) are as follows:

In the normal course of business, the Company enters into contracts and agreements that contain a variety of representations and warranties and may provide for indemnification of the counterparty. The Company’s exposure under these agreements is unknown because it involves claims that may be made against it in the future but have not yet been made. To date, theThe Company has not beenmay, from time to time, be subject to any claims or beenbe required to defend any actionactions related to its indemnification obligations.

The Company indemnifies each of its directors and officers for certain events or occurrences, subject to certain limits, while the director or officer is or was serving at the Company’s request in such capacity, as permitted under Delaware law and in accordance with its certificate of incorporation and bylaws. The term of the indemnification period lasts as long as the director or officer may be subject to any proceeding arising out of acts or omissions of such individual in such capacity. The maximum amount of potential future indemnification is unlimited. The Company believes that the fair value of these indemnification obligations is minimal. Accordingly, the Company has not recognized any liabilities relating to these obligations as of JuneSeptember 30, 2021 and December 31, 2020.

From time to time, the Company may have certain contingent liabilities that arise in the ordinary course of business activities. The Company accrues a liability for such matters when it is probable that future expenditures will be made and such expenditures can be reasonably estimated. The Company determined that no accrual related to contingencies was required as of JuneSeptember 30, 2021 and December 31, 2020.

In November 2014, the Company entered into a Term Loan Agreement, as amended, for total borrowings of up to $40.0 million with Capital Royalty Partners II L.P. and its affiliates Capital Royalty Partners II – Parallel Fund “A” L.P. and Parallel Investment Opportunities Partners II L.P., or collectively, CRG.for total borrowings of up to $40.0 million. As of December 31, 2019, $40.0 million had been funded under this Term Loan Agreement, or the Term Loan. The Term Loan bore interest at a rate of 12.5% per year. Payments under the Term Loan were to be made quarterly with payment dates fixed at the end of each calendar quarter. Through September 30, 2017, the Company had the option to pay interest as follows: 8.0% per year paid in cash and 4.5% per year paid-in-kind, or PIK, by increasing the principal of the Term Loan.

The Term Loan was interest-only through September 30, 2019. Following the interest-only period, principal payments were to be made in equal installments at the end of the next four calendar quarters, with the final payment due on September 30, 2020. The Term Loan included a fee upon repayment of the loan equal to 5% of the aggregate principal amount being prepaid or repaid. The Company ratably accreted the fee over the life of the loan.

In connection with the Term Loan, the Company paid total closing fees of $0.8 million and issued warrants to purchase 219 shares of its Series I redeemable convertible preferred stock at $1,866.80 per share. The initial fair value of the warrants was $0.3 million and resulted in a discount to the Term Loan, which was amortized to interest expense over the life of the loan using the effective interest method. Prior to 2020, these warrants were modified to be exercisable for 219 shares of common stock at $2.60 per share. Upon the closing of the IPO, warrants to purchase 219 shares of common stock net exercised to 185 shares of common stock.

In October 2019, the Term Loan Agreement was amended to extend the interest-only period through December 31, 2019. This amendment was accounted as a debt modification and the impact on the Term Loan’s effective interest rate was a decrease from 15.0% to 14.7%.

In February through June 2020, the Term Loan Agreement was amended to extend the interest-only period through June 30, 2020 and to allow the Company to pay such interest entirely in kind by adding it to the aggregate principal of the loan. The Company paid $1.4 million in interest due on March 31, 2020 in kind and paid $1.4 million in interest due on June 30, 2020 in cash. The amendments were accounted as a debt modification and the Term Loan’s effective interest rate was changed within 14.7% to 14.2% with each amendment.

In September 2020, the Company repaid its entire obligation under the Term Loan amounting to $47.6 million, including principal of $44.1 million, interest of $1.3 million and fees of $2.2 million, using the proceeds from New Term Loan (as defined below). The repayment of the Term Loan was accounted for as a debt extinguishment, which resulted in an immaterial extinguishment loss.

In September 2020, the Company entered into a new Term Loan Agreement with CRG Partners IV L.P. and its affiliates for total borrowings of up to $60.0 million, or the New Term Loan, and borrowed $50.0 million. The remaining $10.0 million of the New Term Loan will be available to the Company for borrowing until March 31, 2022 if the Company achieves a revenue-based milestone in 2021.

The New Term Loan bears interest at a rate of 12.5% per year. Payments under the New Term Loan are made quarterly with payment dates fixed at the end of each calendar quarter. The New Term Loan was interest-only through September 30, 2023, which could be extended through September 30, 2025 at the Company’s option if the Company completed its IPO on or prior September 30, 2023. In connection with closing the IPO, the Company extended the interest-only period to September 30, 2025. Following the interest-only period, principal payment is

The New Term Loan is collateralized by substantially all of the Company’s assets. The New Term Loan Agreement contains customary representations and warranties, covenants, events of default and termination provisions. The financial covenants require that the Company achieve minimum annual revenue thresholds commencing in 2021 and maintain a minimum balance of cash and cash equivalents (see Note 1).

The Company paid $1.0 million in fees to the lender and third parties which is reflected as a discount on the loan and is being accreted over the life of the loan using the effective interest method. Also, the Company issued warrants to the lender for a total of 346,823 shares of Series B’ redeemable convertible preferred stock. The warrants had a fair value of $0.6 million as of the issuance date, which was accounted for as debt issuance costs (see Note 8).

During the three and six months ended JuneSeptember 30, 2021 and 2020, the Company recorded interest expense related to deferred financing and debt issuance costs of the New Term Loan of $0.1 million and less than $0.1 million, respectively. During the nine months ended September 30, 2021 and 2020, the Company recorded interest expense related to deferred financing and debt issuance costs of the New Term Loan of $0.2 million and less than $0.1 million, respectively.

Interest expense on the New Term Loan was $1.9 million and $3.7$0.1 million during the three and six months ended JuneSeptember 30, 2021 and 2020, respectively. Interest expense on the New Term Loan was $5.5 million and $0.1 million during the nine months ended September 30, 2021 and 2020, respectively.

In April 2020, the Company received $4.0 million from a federal Small Business Administration loan under the Paycheck Protection Program, or the PPP Loan. The note bore interest at 1.0% per year on the outstanding principal amount and had a maturity date 24 months from the date of the note. No payments were due for the six-month period beginning on the date of the note. Payments of principal and interest were due over the following 18 months. The Small Business Administration modified the PPP Loan such that monthly payments of principal and interest were due from September 2021 through April 2022. In April 2021, the Company repaid its entire obligation under

In March and September 2019, Company issued convertible notes to certain investors for aggregate proceeds of $21.3 million, or the 2019 Convertible Notes. In January and March 2020, the Company raised $7.1 million and $5.4 million, respectively, through the sale and issuance of additional convertible notes, or the 2020 Convertible Notes. The 2019 and 2020 Convertible Notes were subordinated to the Term Loan, bore interest on the outstanding principal amount at the rate of 8.0% per year, and had a maturity date of December 31, 2020.

Upon the consummation of an equity financing with aggregate proceeds to the Company of not less than $18 million, or the Qualified Financing, the outstanding principal balance of the 2019 and 2020 Convertible Notes and accrued but unpaid interest would convert into shares of capital stock issued in such Qualified Financing at a conversion price equal to 85% of the issuance price per share of such capital stock in such Qualified Financing. In the event the Company consummated, while the 2019 and 2020 Convertible Notes remained outstanding, an equity financing that did not constitute a Qualified Financing, then the majority holders had the option to treat such equity financing as a Qualified Financing. If the Company did not complete a Qualified Financing prior to the maturity date while the 2019 and 2020 Convertible Notes remained outstanding, the holders of the notes could elect to convert the outstanding principal and unpaid accrued interest into the Company’s Series A’ redeemable convertible preferred stock at a conversion price of $116.35 per share.

Upon the occurrence of a change of control, the 2019 and 2020 Convertible Notes would upon the election of the majority holders either (i) become due and payable upon the closing of such change of control in cash in an amount equal to (a) the outstanding principal amount plus any unpaid accrued interest, plus (b) a repayment premium equal to 100% of the outstanding principal amount, or (ii) be converted such that the outstanding principal balance of the notes and any unpaid accrued interest would convert into shares of the Company’s Series A’ redeemable convertible preferred stock at a conversion price equal to $116.35 per share.

The 2019 and 2020 Convertible Notes contained embedded derivative instruments, including automatic conversion into equity securities upon completion of a Qualified Financing, that were required to be bifurcated and accounted for separately as a single derivative instrument initially and subsequently measured at fair value with the change in fair value recorded in other income (expense), net in the statements of operations and comprehensive loss. The issuance date estimated fair values of the derivative instruments issued with the March and September 2019 notes were $4.1 million and $1.9 million, respectively, which were recorded as debt discounts. The issuance date estimated fair values of the derivative instruments issued with the January and March 2020 notes were $1.0 million and $0.7 million, respectively, which were recorded as debt discounts. In August 2020, the derivative instrument was extinguished in connection with the issuance of Series B’ redeemable convertible preferred stock.

The discount on the 2019 and 2020 Convertible Notes was amortized over the contractual term ending on December 31, 2020, using the effective interest method. The annual effective interest rate was estimated from 10.8% to 12.2% per year. The interest expense for the three months ended JuneSeptember 30, 2020 was $2.2$1.0 million, consisting of $1.5$0.2 million of contractual interest expense and $0.7$0.8 million amortization of debt discount arising from separation of the embedded derivative instrument. The interest expense for the sixnine months ended JuneSeptember 30, 2020 was $3.6$4.6 million, consisting of $2.4$1.4 million of contractual interest expense and $1.2$3.2 million amortization of debt discount arising from separation of the embedded derivative instrument.

For the sixnine months ended JuneSeptember 30, 2020, $10.3 million of convertible notes were issued to related parties. The interest expense ofon convertible notes issued to related parties for the three and sixnine months ended JuneSeptember 30, 2020 was $0.6$0.2 million and $1.1$1.3 million, respectively.

In connection with the sale and issuance of Series B’ redeemable convertible preferred stock all outstanding convertible notes were modified to remove the 15% discount on conversion. All outstanding convertible notes of $33.9 million and accrued unpaid interest of $2.5 million were converted into 8,379,410 shares of Series B’ redeemable convertible preferred stock at 100% of the preferred stock issuance price of $4.3423 per share.

The conversion of the 2019 Convertible Notes and 2020 Convertible Notes into shares of Series B' redeemable convertible preferred stock was accounted for as a debt extinguishment with $4.1 million extinguishment gain recognized as a deemed capital contribution to additional paid-in capital in the quarter ended September 30, 2020, as the holders of the notes were existing stockholders of the Company.

In August 2020, the Company amended its Certificate of Incorporation, pursuant to which the Company had 2 series of redeemable convertible preferred stock, designated as Series A’ and Series B’. In August 2020, the Company issued 7,599,720 shares of Series B’ redeemable convertible preferred stock at $4.3423 per share for gross proceeds of $33.0 million. In connection with the issuance of Series B’ redeemable convertible preferred stock, all

As of December 31, 2020, the redeemable convertible preferred stock comprised (in thousands, except per share and share amounts):

On April 26, 2021, upon the closing of the Company’s IPO, all outstanding redeemable convertible preferred stock automatically converted into 16,614,178 shares of common stock. Prior to the closing of the Company’s IPO, the holders of redeemable convertible preferred stock had the following various rights and preferences:

The holders of redeemable convertible preferred stock were entitled to receive dividends, out of any assets legally available therefore, prior and in preference to any declaration or payment of any dividend to the common stockholders, at the rate of $4.6540 per share per annum on each outstanding share of Series A’ redeemable convertible preferred stock and $0.3474 per share per annum on each outstanding share of Series B’ redeemable convertible preferred stock, payable when, as and if declared by the Board of Directors.
