Notes to Condensed Consolidated Financial Statements

(unaudited)

1. Summary of Significant Accounting Policies

Basis of Presentation

The accompanying interim condensed consolidated financial statements as of June 30, 2024 and for the three and six months ended June 30, 2024 and 2023, and the related interim information contained within the notes to the financial statements, are unaudited. The unaudited interim condensed consolidated financial statements (the condensed consolidated financial statements) have been prepared in accordance with generally accepted accounting principles in the United States (U.S. GAAP) for interim financial information and on the same basis as the audited financial statements included on the Company’s Annual Report on Form 10-K for the year ended December 31, 2023 (the Annual Report) filed with the Securities and Exchange Commission (SEC) on February 23, 2024. The condensed consolidated financial statements are prepared in U.S. dollars and include the Company’s accounts and those of its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated. In the opinion of management, the accompanying unaudited interim condensed consolidated financial statements contain all adjustments (consisting of normal recurring adjustments) necessary to state fairly the Company’s financial position as of June 30, 2024, the results of its operations for the three and six months ended June 30, 2024 and 2023 and the consolidated statements of cash flows for the six months ended June 30, 2024 and 2023. All such adjustments are of a normal and recurring nature. The interim financial data as of June 30, 2024 is not necessarily indicative of the results to be expected for the year ending December 31, 2024, or for any future period.

The consolidated balance sheet as of December 31, 2023 was derived from the audited financials as of that date. The accompanying condensed consolidated financial statements and related financial information should be read in conjunction with the audited consolidated financial statements and the related notes thereto for the year ended December 31, 2023 included in the Annual Report.

Use of Estimates

The preparation of financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Estimates are based on historical experience, where applicable, and other assumptions believed to be reasonable by management. Actual results may differ from those estimates under different assumptions or conditions.

Foreign Currency Translation

Unrealized foreign exchange gains and losses from the remeasurement of assets and liabilities denominated in currencies other than the functional currency of the reporting entity are recorded in other income (expense), net. Additionally, realized gains and losses resulting from transactions denominated in currencies other than the local currency are recorded in other income (expense), net in the condensed consolidated statements of operations and comprehensive loss. The Company recorded net unrealized and net realized foreign currency transaction gains (losses) during the periods presented as follows (in thousands):

	Three Months Ended						Six Months Ended
	June 30,						June 30,
	2024			2023			2024			2023
Net unrealized foreign currency gain (loss)	$	(156	)	$	(278	)	$	196		$	(145	)
Net realized foreign currency gain (loss)		(66	)		(9	)		(388	)		(137	)

New Accounting Pronouncements Not Yet Adopted

In December 2023, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2023-09 (Topic 740): Income Taxes: Improvements to Income Tax Disclosures which expands the existing rules on income tax disclosures. This update requires entities to disclose specific categories in the tax rate reconciliation, provide additional information for reconciling items that meet a quantitative threshold and disclose additional information about income taxes paid on an annual basis. The new disclosure requirements are effective for fiscal years beginning after December 15, 2024. The Company is currently evaluating the impact of adopting ASU 2023-09.

7

In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures which expands disclosure requirements to require entities to disclose significant segment expenses that are regularly provided to or easily computed from information regularly provided to the chief operating decision maker. This update also requires all annual disclosures currently required by Topic 280 to be disclosed in interim periods. The new disclosure requirements are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. The Company is currently evaluating the impact of adopting ASU 2023-07.

2. Revenue

The following table presents revenue by geography, based on the billing address of the customer (in thousands):

	Three Months Ended				Six Months Ended
	June 30,				June 30,
	2024		2023		2024		2023
United States	$	90,694	$	92,961	$	177,732	$	175,282
International		13,467		15,848		28,328		29,854
Total revenue	$	104,161	$	108,809	$	206,060	$	205,136

The United States is the only country that accounts for 10% or more of the revenue during the periods presented:

	Three Months Ended						Six Months Ended
	June 30,						June 30,
	2024			2023			2024			2023
United States		87	%		85	%		86	%		85	%

There were no customers that accounted for 10% or more of the Company’s revenue for each of the three and six months ended June 30, 2024 and 2023. Additionally, there were no customers that accounted for 10% or more of the Company’s accounts receivable balance as of June 30, 2024 and December 31, 2023. For the three and six months ended June 30, 2024, the Company recognized bad debt expenses of $0.3 and $0.6 million, respectively. For the three and six months ended June 30, 2023, the Company recognized bad debt expenses of $0.3 million and $0.4 million, respectively.

3. Lease Accounting

The Company has operating leases for office space, a manufacturing facility, warehouse, research and development facilities and equipment. Leases with terms of 12 months or less are not recorded on the balance sheet, as the related lease expenses are recognized on a straight-line basis over the lease term. The Company accounts for lease components (such as fixed payments) separately from non-lease components (such as common area expenses).

In April 2024, the Company entered into an amendment to its office space located in Redwood City, California, which reduced the total office space to approximately 78,000 square feet, beginning on June 1, 2024 and ending on December 31, 2031. Pursuant to the lease amendment, the landlord provided the Company with a tenant improvement allowance of up to $4.7 million. The amendment increased the right-of-use asset and lease liability by $15.5 million.

The weighted average lease terms and discounts rates are as follows:

	June 30, 2024	December 31, 2023
Operating Lease Term and Discount Rate
Weighted-average remaining lease term	7.41 years	2.86 years
Weighted-average discount rate	7.0%	7.0%

As of June 30, 2024, the maturity of lease liabilities are as follows (in thousands):

Thereafter		18,071
Total lease payments		35,636

4. Fair Value Measurements

Cash Equivalents and Short-Term Investments

The Company’s money market funds are classified within Level 1 of the fair value hierarchy and are valued based on quoted prices in active markets for identical securities. The Company’s short-term investments are comprised of agency bonds, commercial paper, corporate notes and treasury bonds. All short-term investments have been classified within Level 1 or Level 2 of the fair value hierarchy because of the sufficient observable inputs for revaluation. The Company’s Level 2 investments are valued using third-party pricing sources. The pricing services utilize industry-standard valuation models, including both income and market-based approaches, for which all significant inputs are observable, either directly or indirectly, to estimate fair value. These inputs include reported trades of and broker/dealer quotes on the same or similar investments, issuer credit spreads, benchmark investments, prepayment/default

Convertible Senior Notes

As of June 30, 2024 and December 31, 2023, the fair value of the 2.75% convertible senior notes due 2025 (the 2025 Notes) was $35.7 million and $35.6 million, respectively. The fair value was determined on the basis of market prices observable for similar instruments and is considered Level 2 in the fair value hierarchy (See Note 7 for additional information regarding the 2025 Notes).

Warrant Liability

In November 2023, the Company entered into a Credit Agreement and Guaranty (the Braidwell Credit Agreement) with Braidwell LP (together with its affiliates, Braidwell). In connection with the Braidwell Credit Agreement, the Company issued warrants (the Braidwell Warrants) to Braidwell to purchase an aggregate of approximately 2.58 million shares of the Company's common stock.

The Braidwell Warrants are valued using the Black Scholes valuation model and are considered Level 3 in the fair value hierarchy. As of June 30, 2024 and December 31, 2023, the fair value of the Braidwell Warrants was $5.7 million and $28.7 million, respectively. Assumptions for the warrant liability are as follows:

	June 30, 2024	December 31, 2023
Expected term (in years)	5.4	6.0
Expected volatility	53%	53%
Risk-free interest rate	4.08%	3.50%
Dividend yield	0%	0%

Contingent Consideration

In connection with the Company's acquisition of Interventional Pain Technologies, Inc. (Vyrsa) in the fourth quarter of 2023, the Company is subject to certain contingent consideration. Changes in the fair value of the contingent consideration liability for the six months ended June 30, 2024 were as follows (in thousands):

Balance as of December 31, 2023	$	22,093
Change in fair value of contingent consideration		4,431
Contingent consideration payments		(9,804	)
Balance as of June 30, 2024	$	16,720

Upon the achievement of the regulatory approval milestone in the three months ended March 31, 2024, the Company accrued an additional $5.0 million and made contingent consideration payments of $9.8 million.

The regulatory approval milestone and product development milestone consideration are valued using the probability-weighted average discount cash flow model, and the revenue milestone consideration is valued using the Monte Carlo simulation model. The contingent consideration is considered Level 3 in the fair value hierarchy. As of June 30, 2024, the fair value of the contingent consideration related to the product development and revenue milestones were $1.7 million and $14.9 million, respectively. As of December 31, 2023, the fair value of the contingent consideration related to the regulatory approval, product development and revenue milestones were $5.0 million, $1.7 million and $15.5 million, respectively.

5. Balance Sheet Components

Cash and Cash Equivalents

The Company considers all highly-liquid investments purchased with an original maturity of three months or less at the date of purchase to be cash equivalents. Cash and cash equivalents include money market funds in the amount of $54.1 million and $82.9 million as of June 30, 2024 and December 31, 2023, respectively. As of June 30, 2024 and December 31, 2023, the Company’s cash equivalents were held at institutions in the United States and include deposits in a money market fund which was unrestricted as to withdrawal or use. The Company also held cash in foreign banks of approximately $13.2 million at June 30, 2024 and $9.4 million at December 31, 2023 that was not insured. The Company has not experienced any losses on its deposits of cash and cash equivalents.

Investments

The Company measures its cash equivalents and short-term investments at fair value, with unrealized gains and losses recorded in accumulated other comprehensive income within stockholders’ equity. The Company regularly reviews its investments and evaluates the current expected credit loss by considering factors such as historical experience, market data, and the near-term

Total securities	$	218,248	$	390	$	(132	)	$	218,506

Realized gains or losses and other-than-temporary impairments, if any, on available-for-sale securities are reported in other income (expense), net as incurred. The cost of securities sold is determined based on the specific identification method. The amount of realized gains and realized losses on investments recorded for the periods presented has not been material.

The contractual maturities of the Company’s investment securities as of June 30, 2024 were as follows (in thousands):

	Amortized Cost		Fair Value
Amounts maturing within one year	$	125,126	$	124,995
Amounts maturing after one year through five years		74,283		73,996

Work in process		12,490		2,149
Finished goods		57,844		51,553
Total inventories	$	126,096	$	118,676

Inventories are stated at the lower of cost or net realizable value. Cost is determined using the standard cost method which approximates the first-in, first-out basis. Net realizable value is determined as the prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. The Company regularly reviews inventory quantities compared to forecasted sales to record a provision for excess and obsolete inventory when appropriate. Inventory write-downs are recorded for excess and obsolete inventory. The Company estimates forecasted sales by considering product acceptance in the marketplace, customer demand, historical sales, product obsolescence and technological innovations.

The Company periodically evaluates the carrying value of inventory on hand for potential excess amount over demand using the same lower of cost or net realizable value approach as that has been used to value the inventory. The Company also periodically evaluates inventory quantities in consideration of actual loss experience. As a result of these evaluations, there was an immaterial change to the carrying value of inventory recognized for the three months ended June 30, 2024 and for the three months ended June 30, 2023, the Company recognized a write-down of $1.6 million. For the six months ended June 30, 2024 and 2023, the Company had write-downs of $0.7 million and $2.8 million, respectively.

6. Commitments and Contingencies

Operating Leases

In March 2015, the Company entered into a lease agreement for approximately 50,000 square feet of office space located in Redwood City, California for a period beginning on June 30, 2015 and ending in May 2022, with initial annual payments of approximately $2.0 million, increasing to $2.4 million annually during the final year of the lease term. In December 2016, the Company entered into a first amendment to the lease for an additional approximately 50,000 square feet of office space adjacent to the premises under the original lease (the Expansion Premises), with initial annual payments of $1.2 million, increasing to $2.9 million in the final year of the amended lease term. The lease for the Expansion Premises commenced on June 1, 2018, and includes an expiration date of May 31, 2025. The first amendment extended the lease term for the original premises to terminate on the same date as the Expansion Premises. In April 2024, the Company entered into a second amendment which reduced the total office space to approximately 78,000 square feet, beginning on June 1, 2024 and ending on December 31, 2031, with initial annual payments of approximately $3.0 million, increasing to approximately $5.7 million during the final year of the lease term. Pursuant to the second lease amendment, the landlord provided the Company with a tenant improvement allowance of up to $4.7 million.

The Company entered into a separate non-cancellable facility lease for warehouse space beginning on March 1, 2017 through February 28, 2022, under which it is obligated to pay approximately $0.4 million in lease payments over the term of the lease. In October 2021, the Company entered into a first amendment of the warehouse lease, which extends the lease term to terminate on May 31, 2025 and under which the Company is obligated to pay approximately $0.4 million over the term of the extension period.

13

In August 2020, the Company entered into a lease for approximately 35,411 square feet of space for a manufacturing facility in Costa Rica to begin in April 2021 and to last through June 2031, under which it is obligated to pay approximately $3.9 million in lease payments over the term of the lease. On the commencement date in April 2021, the Company classified and measured the lease, resulting in the recording of operating assets of $2.9 million and operating lease liabilities of $2.9 million.

See Note 3 for further discussion on Lease Accounting.

Warranty Obligations

The Company provides a limited one- to five-year warranty and warrants that its products will operate substantially in conformity with product specifications. The Company records an estimate for the provision for warranty claims in cost of revenue when the related revenues are recognized. This estimate is based on historical and anticipated rates of warranty claims, the cost per claim and the number of units sold. The Company regularly assesses the adequacy of its recorded warranty obligations and adjusts the amounts as necessary. Activities related to warranty obligations were as follows (in thousands):

	Three Months Ended						Six Months Ended
	June 30,						June 30,
	2024			2023			2024			2023
Beginning balance	$	2,004		$	1,147		$	1,531		$	866

Ending balance	$	2,200		$	1,349		$	2,200		$	1,349

Supply Agreements

The Company has entered into supply agreements with certain suppliers that require certain minimum annual purchase agreements. As of June 30, 2024, the Company had minimum annual purchase commitments of $6.3 million due for the remainder of 2024 and $4.9 million due in 2025. In addition, the Company renegotiated a supplier contract resulting in a one-time $6.0 million fee, recorded in accrued liabilities and expensed to cost of revenue as of June 30, 2024. The renegotiation reduced the Company’s future purchase commitments enabling the company to accelerate the move of inventory production to its Costa Rica facility.

Contingencies

From time to time, the Company may have certain contingent liabilities that arise in the ordinary course of business activities related to, for example, employment matters and patent issues. 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. When determining the estimated loss or range of loss, significant judgment is required.

Indemnification

The Company enters into standard indemnification arrangements in the ordinary course of business. Pursuant to these arrangements, the Company indemnifies, holds harmless and agrees to reimburse the indemnified parties for losses suffered or incurred by the indemnified party, in connection with any trade secret, copyright, patent or other intellectual property infringement claim by any third-party with respect to the Company’s technology. The term of these indemnification agreements is generally perpetual. The maximum potential amount of future payments the Company could be required to make under these agreements is not determinable because it involves claims that may be made against the Company in the future, but have not yet been made.

The Company has entered into indemnification agreements with its directors and officers that may require the Company to indemnify its directors and officers against liabilities that may arise by reason of their status or service as directors or officers, other than liabilities arising from willful misconduct of the individual. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is unlimited; however, the Company has director and officer insurance coverage that reduces the Company’s exposure and enables the Company to recover a portion of any future amounts paid. The Company believes the estimated fair value of these indemnification agreements in excess of applicable insurance coverage is minimal.

14

Legal Matters

The Company is and may from time to time continue to be involved in various legal proceedings to defend its intellectual property, including several pending European patent oppositions at the European Patent Office (EPO) initiated by the Company’s competitors Medtronic and Boston Scientific. In addition, the Company is and may from time to time also be involved in various legal proceedings, such as employment matters, product liability matters, and professional liability matters, which the Company does not deem to be material to its business and condensed consolidated financial statements at this stage.

Flathead Partners Litigation/Arbitration

On July 15, 2022, the Company filed a lawsuit in the U.S. District Court for the Northern District of California for breach of contract against Flathead Partners, LLC, the Mayo Foundation for Medical Education and Research, and Mayo Clinic Ventures (herein referred to as “Flathead Partners”). The Company’s suit alleged that Flathead Partners breached the 2006 license agreement between the Company and the Mayo Clinic (referred to in the Company’s 10-K filing as the “Mayo License”), when Flathead Partners unilaterally asserted control of pending U.S. Patent Application 16/286,389 (the “’389 Application”), which is subject to the Mayo License. The suit sought to enjoin the Flathead Partners from taking any action at the U.S. Patent Office with respect to the ‘389 Application, and to thereafter engage in an arbitration as called for in the Mayo License. On July 27, 2022, the Flathead Partners agreed to enter into an arbitration to determine which party shall have control of prosecution of the ‘389 Application, and whether there are ongoing royalty obligations under the Mayo License. Therefore, Nevro dismissed the lawsuit in the Northern District of California. The parties then engaged in an arbitration. An arbitration hearing was held during the week of September 11, 2023, and a ruling was issued on April 8, 2024 requiring that Flathead Partners transfer back to the Company the power to control and direct prosecution of the ‘389 Application and its patent family. The April 8, 2024 ruling also concluded that Nevro did not owe Flathead Partners royalties under the Mayo License. More specifically, the Arbitrator found that Flathead Partners had breached the Mayo License, and that the Company had not breached the Mayo License. The Arbitrator awarded the Company (i) $0.2 million in damages, paid by Flathead Partners in May 2024; (ii) the Company’s attorneys’ fees and costs for the Northern District of California litigation (a final amount to be awarded after accounting submissions in August 2024); and (iii) prejudgment interest at a rate of 10%, with prejudgment interest running from June 1, 2022 (a final amount to be calculated in August 2024).

Civil Investigative Demand

In December 2022, the Company received a civil investigative demand (CID) pursuant to the federal False Claims Act from the United States Attorney’s Office for the Northern District of California seeking information relating to the Company’s spinal cord stimulation system (SCS System). The CID primarily relates to marketing, promotion and billing practices, not the therapeutic or safety attributes of the Company’s SCS System. The Company maintains rigorous policies and procedures designed to promote compliance with the federal False Claims Act and other regulatory requirements, and is cooperating in this matter and providing the requested information.

2025 Notes and Convertible Note Hedge and Warrant Transactions

During the three months ended June 30, 2024, the conditions allowing holders of the 2025 Notes to convert have not been met. Therefore, the 2025 Notes are not convertible during the three months ended September 30, 2024. As of June 30, 2024, the if-converted value of the 2025 Notes did not exceed the principal value of those notes.

Credit Agreement with Braidwell LP

The Braidwell Credit Agreement provides for a term loan facility in the amount of $200.0 million, which was funded in its entirety in November 2023. Loans borrowed pursuant to the Braidwell Credit Agreement (the Braidwell Term Loans) bear interest at a rate per annum equal to Term Secured Overnight Financing Rate (as defined in the Braidwell Credit Agreement and with a floor of 3.50%) plus 5.25%. At the option of the Company, a portion of the interest payable on the Braidwell Term Loans equal to (i) (a) on or prior to the first anniversary of the Closing Date (as defined in the Braidwell Credit Agreement), 5.25%, (b) following the first anniversary of the Closing Date and on or prior to the third anniversary of the Closing Date, 2.50% and (c) following the third anniversary of the Closing Date, 1.50%, may be paid in-kind rather than in cash. The portion of the interest payable that the Company elects to be paid-in-kind results in an increase to the principal of the Braidwell Term Loans, which for the three and six months ended June 30, 2024 was $2.8 million and $5.4 million, respectively. The Braidwell Term Loans do not amortize, and have a maturity date of November 30, 2029. As of June 30, 2024, the Company was in compliance with covenants under the Braidwell Credit Agreement.

The net carrying amount of the liability component of the Braidwell Term Loans was as follows (in thousands):

9. Stock-Based Compensation

The Company accounts for stock-based compensation arrangements with employees in accordance with Accounting Standards Codification (ASC) 718, Compensation—Stock Compensation. ASC 718 requires the recognition of compensation expense, using a fair value-based method, for costs related to all share-based payments including stock options. The Company estimates forfeitures expected to occur to determine the amount of compensation cost recognized in each period.

In addition to restricted stock units, the Company grants performance stock units (PSUs) to certain members of the management team. These PSUs vest over a three-year period, subject to continued service, and are based on (1) the total shareholder return (TSR) of the Company’s common stock price compared to the S&P Healthcare Equipment Select Industry Index (the Index) over a two-year period or (2) specific revenue targets over a two-year performance period. Additionally, in 2022, the Company made PSU grants to its then CEO that included attainment criteria that required the Company's stock price to reach certain pre-specified stock prices. Since TSR and stock price attainment are considered market conditions, the PSUs based on TSR and stock price attainment have fair values that are determined at the grant date using the Monte Carlo simulation model, with the recorded expense based on fair value. Since revenue targets are considered performance conditions, the PSUs based on revenue targets have a fair value that is equal to the closing stock price on the grant date, with the recorded expense based on the fair value and the probability of achievement, which is reassessed at each reporting period.

The PSU grant activity is as follows:

	Three Months Ended				Six Months Ended
	June 30, 2024				June 30, 2024
	Shares		Weighted Average Fair Value		Shares		Weighted Average Fair Value
Total shareholder return		6,110	$	15.80		245,833	$	20.89

Revenue targets		85,395	$	32.10		172,952	$	32.20
Total PSUs granted		170,788	$	38.39		345,876	$	38.65

10. Basic and Diluted Net Income (Loss) Per Share

Basic net loss per share is computed by dividing the net loss by the weighted average number of common shares outstanding for the period. Diluted net income (loss) per share is computed by dividing the net income (loss) by the weighted average number of common shares and dilutive common stock equivalents outstanding for the period, if inclusion of these is dilutive. The Company uses the if-converted method and presumes share settlement for its 2025 Notes when calculating the dilutive effect of these notes. In connection with the offerings of the convertible senior notes, the Company entered into convertible note hedges and warrants. However, the convertible note hedges are not included when calculating potentially dilutive shares since their effect is always anti-dilutive. Warrants were considered anti-dilutive to the extent that their strike price were above the Company's average share price during the period.

The following table summarizes the computation of basic and diluted net loss per share (in thousands, except share and per share data):

	Three Months Ended						Six Months Ended

11. Employee Benefit Plans

401(k) Plan

In 2007, the Company adopted a 401(k) plan for its employees whereby eligible employees may contribute up to the maximum amount permitted by the Internal Revenue Code. In June 2016, the Company adopted a policy to match a portion of employee contributions for all qualified employees participating in the 401(k) plan. The Company recorded an expense for matching contributions of $0.7 million and $0.6 million for the three months ended June 30, 2024 and 2023, respectively, and $3.0 million and $3.1 million for the six months ended June 30, 2024 and 2023.

12. Restructuring

On January 6, 2024, the Company approved a restructuring plan to accelerate its path to profitability that included laying off 63 employees, which represented approximately 5% of the Company’s total number of employees. Operating expenses for the three months ended March 31, 2024 reflected a $5.5 million restructuring charge, consisting of one-time severance and other termination benefit costs. On May 5, 2024, the Company approved additional restructuring steps to further accelerate its path to profitability. Operating expenses for the three months ended June 30, 2024 reflected a $4.6 million restructuring charge, consisting of one-time severance and other termination benefit costs. As of June 30, 2024, substantially all severance and other termination benefit amounts have been paid.

Overview

We are a global medical device company focused on delivering comprehensive, life-changing solutions that continue to set the standard for enduring patient outcomes in chronic pain treatment. We have developed and commercialized our HFX™ spinal cord stimulation (SCS) platform, which includes the Senza® SCS system, an evidence-based neuromodulation system for the treatment of chronic pain, with the Senza® HFX iQ™ platform being our latest addition to the Senza family of products. Our HFX solution is approved to deliver a versatile range of waveforms, including our proprietary, paresthesia-free 10 kHz Therapy. Our 10 kHz Therapy was demonstrated in our SENZA randomized controlled trial (RCT) to be superior to traditional SCS therapy, with 10 kHz Therapy being nearly twice as successful in treating back pain and 1.5 times as successful in treating leg pain when compared to traditional SCS therapy. In addition to the original approval of our therapy in back and leg pain, we received approval of our 10 kHz Therapy for the management of chronic intractable pain of the lower limbs, including unilateral or bilateral pain, associated with painful diabetic neuropathy (PDN) in July 2021 in the United States. We received expanded labeling in non-surgical back pain (NSBP) in January 2022 in the United States. Our SENZA-RCT study, along with our SENZA-PDN clinical study, SENZA-NSRBP clinical study and European studies, represents what we believe is the most robust body of clinical evidence for any SCS therapy. We believe the superiority of 10 kHz Therapy over traditional SCS therapies will allow us to capitalize on and expand the approximately $2.3 billion global SCS market by treating patients with debilitating chronic pain, including back and leg pain, NSBP and PDN.

We launched Senza commercially in the United States in May 2015, after receiving a label from the U.S. Food and Drug Administration (FDA) supporting the superiority of our 10 kHz Therapy over traditional SCS. The Senza system has been commercially available in certain European markets since November 2010 and in Australia since August 2011. Senza is currently reimbursed by all of the major insurance providers.

In November 2023, we acquired Vyrsa Technologies (Vyrsa), who developed and manufactured a portfolio of Sacroiliac (SI) Joint Fusion devices, expanding our chronic pain portfolio to treat patients diagnosed with SI Joint Dysfunction. With the addition of SI Joint to our pain portfolio, we are able to enter a growing market that builds upon our current customer base, leverages our existing sales force and the addition of the NevroV1™, NevroFix™ and NevroPro™ SI Joint products to our portfolio provides physicians we work with today with another option for treating their chronic pain patients.

In April 2023, we enrolled the first patient in our PDN Sensory study, the first prospective RCT to assess the restoration of neurological function as a primary objective in patients with intractable PDN. The study will enroll up to 236 patients at multiple sites across the United States. Patients will be randomized to conventional medical management (CMM) or 10 kHz Therapy plus CMM, with optional crossover to the other treatment arm at 6 months if those specific criteria are met. Given that enrollment was proceeding ahead of schedule, we executed a pre-planned pause in enrollment in May 2024 to allow for an interim primary endpoint analysis by

20

an independent statistician of all subjects who are randomized to date. With this milestone, we hope to bring the results of this study to physicians sooner than initially contemplated to potentially accelerate adoption. We still may return to enrolling additional patients in the future.

The tables below set forth our revenue from U.S. and international sales the past ten quarters on a quarterly basis and total revenue for each of the past five full fiscal years.

Since our inception, we have financed our operations primarily through equity and debt financings and borrowings under a debt facility. Our accumulated deficit as of June 30, 2024 was $744.4 million. A significant amount of our capital resources has been used to support the development of our Senza products and our 10 kHz Therapy, and we have also made a significant investment building our U.S. commercial infrastructure and sales force to support our commercialization efforts in the United States. We intend to continue to make significant investments in our U.S. commercial infrastructure, including building out a sales organization that targets physician specialties involved in PDN treatment decisions, as well as in research and development (R&D), and in conducting clinical trials to support our future regulatory submissions. In order to further enhance our R&D efforts, pursue product expansion opportunities or acquire a new business or products that are complementary to our business, we may choose to raise additional funds, which may include future equity and debt financings.

We rely on third-party suppliers for the components of our Senza products. Several of these suppliers are currently single-source suppliers. We are also required to maintain high levels of inventory, and, as a result, we are subject to the risk of inventory obsolescence and expiration, which may lead to inventory impairment charges. Additionally, our dependence on third-party suppliers makes us vulnerable to supply shortage problems and exposes us to greater lead times, increasing our risk of inventory obsolescence. In the third quarter of 2020, we made the strategic decision to vertically integrate the assembly of IPG’s, peripherals and various other manufacturing related activities to mitigate our reliance on third-party manufacturers and improve our long-term gross margins. We plan on conducting these manufacturing activities in our facility in Costa Rica, for which our lease began in April 2021. The integration process was completed in mid-2022, and we received approval from the FDA for the manufacture of our Senza system in the Costa Rica facility in September 2022. Even with the commencement of manufacturing in Costa Rica, we have continued to rely on third-party manufacturers as we ramped our factory and in order to provide key components to support the assembly process. We have incurred and may continue to incur significant capital expenditures and implementation costs in our Costa Rica facility.

Macroeconomic Conditions

Our business and financial performance are significantly impacted by macroeconomic conditions. Global macroeconomic challenges, such as the effects of the ongoing war between Russian and Ukraine, the conflict in the Middle East, political instability, supply chain constraints, market uncertainty, volatility in exchange rates, inflationary trends, lower consumer confidence and evolving dynamics in the global trade environment have impacted our business and financial performance. Such economic impacts could also impact the decision of patients and customers to seek and undertake elective procedures which would adversely impact our revenue and results of operations.

Furthermore, a recession or market correction resulting from other macroeconomic factors could materially affect our business and the value of our common stock. The occurrence of any such events may lead to reduced disposable income and access to health insurance which could adversely affect the number of products sold as a result of customer and patient reluctance to seek elective care treatment due to increase patient copays and similar financial considerations.

Adverse macroeconomic conditions, other pandemics or international tensions, could also result in significant disruption of global economic conditions and consumer trends, as well as a significant disruption in financial markets, reducing our ability to access capital, which could in the future negatively affect our liquidity, including our ability to repay our 2025 Notes and the Braidwell Term

21

Loans. Our ability to repay the 2025 Notes and the Braidwell Term Loans could also be adversely impacted by higher interest rates which could make it more difficult to access capital on favorable terms, or at all.

Important Factors Affecting our Results of Operations

We believe that the following factors have impacted, and we expect will continue to impact, our results of operations.

Macroeconomic Environment

The global economy is experiencing increased inflationary pressures, increased interest rates, supply chain issues, recession fears and lower consumer confidence as a result of current macroeconomic environment and geopolitical conditions. Higher interest rates and capital costs, increased costs of labor and volatile currency exchange rates are creating additional economic challenges. These conditions may cause patients to delay their decisions to seek medical elective procedures.

Furthermore, healthcare providers are experiencing and may continue to experience financial and operational pressures as a result of staffing shortages, the supply chain environment and increased inflation, which could impact their decision to prioritize medical elective procedures.

Importance of Physician Awareness and Acceptance of Our Products

We continue to invest in programs to educate physicians who treat chronic back and leg pain about the advantages of our products. This requires significant commitment by our marketing team and sales organization, and can vary depending upon the physician’s practice specialization, personal preferences and geographic location.

Reimbursement and Coverage Decisions by Third-Party Payors

Healthcare providers in the United States generally rely on third-party payors, principally federal Medicare, state Medicaid and private health insurance plans, to cover and reimburse all or part of the cost of our products and the related implant procedure for patients. The revenue we are able to generate from sales of our products depends in large part on the availability of reimbursement from such payors. Currently, there is a National Coverage Determination (NCD 160.7) that provides the conditions for coverage by Medicare as a late (if not last) resort for patients with chronic intractable pain. This broad coverage is inclusive of all our approved indications such as Failed Back Surgery Syndrome, Painful Diabetic Neuropathy (PDN), and Non Surgical Refractory Back Pain (NSBP). The local Medicare Administrative Contractors (MACs) cannot be more restrictive in coverage than this NCD. Only one MAC, Noridian, still has a Local Coverage Determination (LCD) which does not limit based on indications but does have a finite list of diagnosis they deem to meet medical necessity criteria. Decisions of coverage and reimbursement for Senza and the related implant procedure from private health insurance providers can vary. In general, these decisions require that such payors perform analyses to determine if the procedure is medically necessary and if our technology is a covered benefit under the patient's existing policies. These payors may deny pre-service prior authorization if they determine that the device or procedure is not medically necessary for the patient and used in accordance with the payor’s coverage policy. Pre-service denials are able to be appealed through various channels with medical necessity decisions often made by third-parties based on an individual patient’s medical history.

A significant component of our commercial efforts includes working with private payors to ensure positive coverage decisions for our products. For our traditional chronic back and leg pain market, we believe that favorable coverage and reimbursement for procedures using our products from Medicare and certain commercial payors, such as Aetna, Cigna, Humana, Blue Cross Blue Shield (BCBS) and United Healthcare, have contributed to our increase in revenue to date. Although the largest commercial payors and Medicare cover procedures using Senza, there can be no assurance that all private health insurance plans will cover the therapy. While Medicare, through both national and local coverage policies, currently provides coverage for NSBP, most commercial payors do not yet have coverage policies for NSBP and may consider coverage for this indication on a case-by-case basis.

Effective April 14, 2024, Carelon and Anthem BCBS updated their medical policy to explicitly cover PDN. These health plans cover approximately 44 million covered lives and brings total PDN coverage to over 250 million covered lives.

With respect to both PDN and NSBP, there are still some payors that have not yet updated their policies to expressly cover SCS procedures, including in the case of PDN, Cigna and Humana. Nevro’s Patient Access team supports case-by-case approvals for these indications with these payors, however, a significant number of negative coverage and reimbursement decisions by private insurers may impair our ability or delay our ability to grow our revenue.

We are working to expand payor coverage to include the use of our 10 kHz Therapy for the management of PDN and NSBP. This effort could be costly and could take many years to gain broad acceptance, and there can be no guarantee that it will be successful.

22

Inventory Buildup and Supply Chain Management

Our products are composed of a substantial number of individual components and, in order to market and sell them effectively, we must maintain high levels of inventory. We have continued to add suppliers to fortify our supply chain and we have maintained increased levels of inventory. As a result, a significant amount of our cash used in operations has been associated with maintaining these levels of inventory. There may also be times in which we determine that our inventory does not meet our product requirements. The manufacturing process for our products requires lengthy lead times, during which components may become obsolete. We may also over or underestimate the quantities of required components, in which case we may expend extra resources or be constrained in the amount of end product that we can produce. Additionally, as we release later generations of products that contain advancements or additional features, the earlier generations may become obsolete. These factors subject us to the risk of inventory obsolescence and expiration, which may lead to inventory impairment charges. The sum of the charges for the items listed above were $0.7 million for the six months ended June 30, 2024 and $2.1 million for the year ended December 31, 2023.

Investment in Research and Clinical Trials

We intend to continue investing in R&D to help our commercialization efforts around and to expand into new indications and chronic pain conditions, as well as develop product enhancements to improve outcomes and enhance the physician and patient experience. For example, we commenced commercial launches of Surpass, our surgical lead product family in early 2017 and Senza II SCS System in late 2017. We launched our Senza Omnia platform, in the United States in late 2019, in Europe during the second quarter of 2020 and in Australia in July 2020. In the first quarter of 2021, we received FDA approvals for our first Senza Omnia upgrade and a new trial stimulator. In July 2021, we received FDA approval of our 10 kHz Therapy for the management of chronic intractable pain of the lower limbs, including unilateral or bilateral pain, associated with PDN. In January 2022, we received regulatory approval for expanded labeling to include NSBP. In October 2022, we received FDA approval of our latest generation SCS system, HFX iQ™, which we launched on a limited basis in the United States in the fourth quarter of 2022 and more fully in 2023. We are continuing to invest in product improvements to Senza, including enhanced MRI capabilities and next generation IPGs. While R&D and clinical testing are time consuming and costly, we believe expanding into new indications, implementing product improvements and continuing to demonstrate the efficacy, safety and cost effectiveness of the 10 kHz Therapy through clinical data are all critical to increasing the adoption of this therapy.

The SENZA-PDN study was one of the largest RCT conducted in the field of spinal cord stimulation with 216 randomized patients. The study evaluated paresthesia-free 10 kHz Therapy among patients diagnosed with PDN and refractory to CMM. Patients were randomized one-to-one to CMM alone or CMM with 10 kHz Therapy. A crossover study design was used, where subjects who did not have adequate pain relief at 6 months were given the option to cross over to the other treatment arm. Subjects were followed for 24 months, with subjects who crossed over from CMM alone to CMM with 10 kHz Therapy followed for 24 months post-implantation. In April 2021, the six-month data were published online in JAMA Neurology. In July 2021, the FDA approved the Senza System for the treatment of chronic intractable pain of the lower limbs, including unilateral and bilateral pain, associated with PDN. This approval is specific to Nevro’s unique 10 kHz SCS stimulation, and the Senza system was the first spinal cord stimulation system approved by the FDA with a specific indication to treat PDN. In September 2022, the study was completed, and the study results have been presented at numerous conferences and published in multiple journal publications.

Our other large RCT, the SENZA-NSRBP study, was executed to support the new indication for treatment of non-surgical back pain (NSBP) which includes patients with NSBP. NSBP is defined as chronic back pain in patients who have not had previous spine surgery, and based on an assessment from a spine surgeon, are not surgical candidates. The study compared patients receiving 10 kHz Therapy plus CMM to patients receiving CMM alone. In January 2022, the FDA approved the Senza System as an aid in the management of NSBP (intractable back pain without prior surgery and not a candidate for back surgery) based on 6 month efficacy data showing profound improvements in pain and function with 10 kHz Therapy over CMM alone. At the 2022 NANS conference, we presented our 12-month results, including six-month crossover patient data, for the SENZA-NSRBP study. Key findings at 12 months showed profound improvements in pain relief, function, quality of life measures, awareness of positive change and reduction in daily opioid use in NSBP patients receiving 10 kHz Therapy at 12-months post-implant. Results also included comparable improvements for patients that crossed over from CMM to 10 kHz after 6 months. In February 2022, the SENZA-NSRBP 12-month results were published online in the Journal of Neurosurgery: Spine. Finally, in January 2023, we presented the full 24-month results from the SENZA-NSRBP study at the 2023 NANS conference, and the full manuscript reporting the 24-month results was published in Journal of Neurosurgery: Spine in November 2023. We have utilized this 24-month publication in our Patient Access efforts by successfully obtaining case-by-case prior authorization approvals in the absence of defined payor medical policies or explicit non-coverage policies. We expect that this 24-month publication will be critical in efforts to expand payor coverage for this patient cohort.

23

Significant Investment in U.S. Sales Organization

In 2021, we established a sales organization to support the launch of our PDN indication in the United States. This sales organization targets physician specialties involved in PDN treatment decisions, including primary care physicians, endocrinologists, internal medicine and podiatrists, to create awareness of 10 kHz Therapy to treat PDN patients. We are continuing to make investments in building our U.S. commercial infrastructure and recruiting and training our U.S. sales force. This is a lengthy process that requires recruiting appropriate sales representatives, establishing and, on occasion, refining a commercial infrastructure in the United States and training our sales representatives. Following initial training for Senza, our sales representatives typically require lead time in the field to grow their network of accounts and produce sales results. Successfully recruiting and training a sufficient number of productive sales representatives has been required to achieve growth at the rate we expect.

Access to Hospital Facilities

In the United States, in order for physicians to use our products, the hospital facilities where these physicians treat patients often require us to enter into purchasing contracts directly with the hospital facilities or with the Group Purchasing Organizations of which the hospital facilities are members. This process can be lengthy and time-consuming and requires extensive negotiations and management time. In Europe, we may be required to engage in a contract bidding process in order to sell our products, where the bidding processes are only open at certain periods of time, and we may not be successful in the bidding process.

Critical Accounting Policies, Significant Judgments and Use of Estimates

Our management’s discussion and analysis of financial condition and results of operations are based upon our condensed consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP). The preparation of these condensed consolidated financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses. On an ongoing basis, we evaluate our critical accounting policies and estimates. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable in the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions and conditions. Our significant accounting policies are more fully described in Note 1, Summary of Significant Accounting Policies, of Notes to Condensed Consolidated Financial Statements. There have been no other significant or material changes in our critical accounting policies during the six months ended June 30, 2024 to the items we disclosed as our critical accounting policies in Management’s Discussion and Analysis of Financial Conditions and Results of Operations in our Annual Report.

Components of Results of Operations

Revenue

Our revenue is generated primarily from sales to two types of customers: hospitals and outpatient medical facilities, with each being served primarily through a direct sales force. Sales to these entities are billed to, and paid by, the hospitals and outpatient medical facilities as part of their normal payment processes, with payment received by us in the form of an electronic transfer, check or credit card payment. Product sales to third-party distributors are billed to and paid by the distributors as part of their normal payment processes, with payment received by us in the form of an electronic transfer.

U.S. revenue is generally recognized after our sales representatives deliver our product at the point of implantation and upon the completion and authorization of the implant procedure. In response to competitive practices and pressures, we have offered some volume price discounting for larger orders, where products are ordered in advance of an implantation and revenue is recognized when the transfer of control occurs at the time of shipment.

Revenue from sales fluctuates based on the selling price of the products, as the average sales price of our products vary geographically and by the generation of the product sold, and based on the mix of sales by geography. Our revenue from international sales can also be significantly impacted by fluctuations in foreign currency exchange rates, as our sales are denominated in the local currency in the countries in which we sell our products.

We expect our revenue to fluctuate from quarter to quarter due to a variety of factors, including seasonality. For example, the industry generally experiences lower revenues in the first and third quarters of the year and higher revenues in the fourth quarter. Our revenue has been impacted by these industry trends. Further, the impact of the buying patterns and implant volumes of hospitals and medical facilities, and third-party distributors may vary, and as a result could have an effect on our revenue from quarter to quarter.

24

Cost of Revenue

Cost of revenue consists primarily of acquisition costs of components of our products, manufacturing overhead, scrap and inventory excess and obsolescence charges, as well as distribution-related expenses, such as logistics and shipping costs, net of costs charged to customers.

We calculate gross margin as revenue less cost of revenue divided by revenue. Our gross margin has been and will continue to be affected by a variety of factors, but primarily by our average sales price and the costs to have our products manufactured. While costs are primarily incurred in U.S. dollars, international revenue may be impacted by the appreciation or depreciation of the U.S. dollar, which may impact our overall gross margin. Our gross margin is also affected by our ability to reduce manufacturing costs as a percentage of revenue.

Operating Expenses

Our operating expenses consist of R&D expense and sales, general and administrative (SG&A) expenses, amortization of intangibles and change in fair value of contingent consideration. Personnel costs are the most significant component of operating expenses and consist primarily of salaries, bonus incentives, benefits, stock-based compensation and sales commissions.

Research and Development. R&D costs are expensed as incurred. R&D expense consists primarily of personnel costs, including salary, employee benefits and stock-based compensation expenses for our R&D employees. R&D expense also includes costs associated with product design efforts, development prototypes, testing, clinical trial programs and regulatory activities, contractors and consultants, equipment and software to support our development, facilities and information technology. We expect product development expenses to increase in absolute dollars as we continue to develop product enhancements to our products. Our R&D expenses may fluctuate from period to period due to the timing and extent of our R&D and clinical trial expenses.

Sales, General and Administrative. SG&A expense consists primarily of personnel costs, including salary, employee benefits and stock-based compensation expenses for our sales and marketing personnel, including sales commissions, and for administrative personnel that support our general operations, such as information technology, executive management, financial accounting, customer service and human resources personnel. We expense commissions at the time of the sale. SG&A expense also includes costs attributable to marketing, as well as travel, intellectual property and other legal fees, financial audit fees, insurance, fees for other consulting services, depreciation and facilities.

In 2021, we established a sales organization to support the launch of our PDN indication in the U.S. This sales organization targets physician specialties involved in PDN treatment decisions, including primary care physicians, endocrinologists, internal medicine and podiatrists, to create awareness of 10 kHz Therapy to treat PDN patients. We have continued to invest significant spend in marketing efforts in order to generate additional sales opportunities. Additionally, we have made substantial investments in our U.S. commercial infrastructure to support our commercialization efforts in the United States. We expect SG&A expenses to decrease as a percent of revenue as we engage in activities that leverage our existing sales and marketing personnel to support the commercialization of our products in the United States.

In the years leading up to 2022, we had experienced significant legal expenses associated with our intellectual property litigation with Boston Scientific. We continued to incur significant legal expenses associated with intellectual property litigation in 2023. Additionally, we continue to incur significant expenses related to audit, legal, regulatory and tax-related services associated with maintaining compliance with exchange listing and SEC requirements, including compliance under the Sarbanes-Oxley Act of 2002 (the Sarbanes-Oxley Act), director and officer insurance premiums and investor relations costs associated with being a public company. Our SG&A expense may fluctuate from period to period due to the seasonality of our revenue and the timing and extent of our SG&A expense.

Amortization of Intangibles. Our amortization expense relates to intangible assets acquired in a business combination or asset acquisition.

Change in Fair Value of Contingent Consideration. Our acquisition of Vyrsa includes a contingent consideration arrangement, for which we recognized a liability equal to the fair value of the contingent payments we expect to make. We re-measure this liability each reporting period and record any changes in fair value. Changes in discount rates, periods, timing and amount of projected revenue or timing or likelihood of achieving milestones may result in changes in the fair value.

Interest Income and Interest Expense

Interest income consists primarily of interest income earned on our investments and interest expense consists of interest paid on our outstanding debt and the amortization of debt discount and debt issuance costs.

Change in Fair Value of Warrants

The value of the Braidwell Warrants are remeasured to the Fair Market Value at the end of each reporting period while they remain outstanding. The change in the fair value of these warrants are recorded as change in fair value of warrants in our condensed consolidated statements of operations.

Other Income (Expense), Net

Other income (expense), net consists primarily of foreign currency transaction gains and losses and the gains and losses from the remeasurement of foreign-denominated balances to the U.S. dollar.

Provision for Income Taxes

The provision for income taxes consists primarily of income taxes in foreign jurisdictions in which we conduct business as well as states where we have determined we have state nexus. We maintain a full valuation allowance for all of our U.S. deferred tax assets including net operating loss (NOL) carryforwards and federal and state tax credits.

The increase was primarily due to an increase in personnel expenses of $0.9 million and clinical trials expenses of $0.7 million, partially offset by a decrease in development expenses of $0.4 million and office expenses of $0.3 million.

Sales, General and Administrative Expense. SG&A expenses decreased to $76.8 million in the three months ended June 30, 2024, from $86.8 million in the three months ended June 30, 2023, a decrease of $10.0 million, or 12%.

The increase of interest expense from the Braidwell Credit Agreement was partially offset by a decrease of $1.3 million in interest expense and amortization of debt issuance costs for the 2025 Notes, due to our repurchase of $151.7 million in principal of our 2025 Notes in December 2023.

Change in Fair Value of Warrants. The value of the outstanding Braidwell Warrants requires remeasurement at each reporting date. The change in the fair value of these warrants was a gain of $9.5 million in the three months ended June 30, 2024.

Liquidity, Capital Resources and Plan of Operations

Since our inception, we have financed our operations through revenue generated from our operations, private placements of preferred stock, the issuance of common stock in our IPO in November 2014 and our underwritten public offering in June 2015, borrowings under our credit facility, which we have subsequently repaid, and the June 2016 issuance of convertible senior notes due 2021 (2021 Notes). In April 2020, we completed a concurrent underwritten public offering of common stock and convertible senior notes due 2025. Our total net proceeds from the April 2020 offerings, after giving effect to the note hedge transactions and warrant transactions and associated offering expense, was $313.3 million. On June 1, 2021, our outstanding 2021 Notes matured and we paid $172.5 million to settle the outstanding principal and issued 682,912 shares of common stock to holders who elected to convert the 2021 Notes. In November 2023, we entered into the Braidwell Credit Agreement for $200.0 million, and we used portions of the proceeds to repurchase $151.7 million of our 2025 Notes. As of June 30, 2024, we had cash, cash equivalents and short-term investments of $273.7 million. Based on our current operating plan, we expect that our cash and cash equivalents on hand, together with the anticipated funds from the collection of our receivables, will be sufficient to fund our operations through at least the next 12 months.

We expect to incur continued expenditures in the future in support of our commercial infrastructure and sales force. In addition, we intend to continue to make investments in the further development of our products, including ongoing R&D programs and conducting clinical trials. In order to further enhance our R&D efforts, pursue product expansion opportunities or acquire a new business or products that are complementary to our business, we may choose to raise additional funds.

We may continue to seek funds through equity or debt financings, or through other sources of financing. Adequate additional funding may not be available to us on acceptable terms or at all. Our failure to raise capital in the future could have a negative impact

29

on our financial condition and our ability to pursue our business strategies. Should we choose to raise additional capital, the requirements will depend on many factors, including:

•the impact from any recession or other adverse macroeconomic conditions, including but not limited to increased interest rates, inflationary pressures, geopolitical conflicts and lower consumer confidence;

•the costs related to the continued commercialization of our products in the United States and elsewhere, including product sales, marketing, manufacturing and distribution;

•the cost of filing, prosecuting, defending and enforcing any patent claims and other intellectual property rights;

•the R&D activities we intend to undertake in order to expand the chronic pain indications and product enhancements that we intend to pursue;

•whether or not we pursue acquisitions or investments in businesses, products or technologies that are complementary to our current business;

•the degree and rate of market acceptance of our products in the United States and elsewhere;

•changes or fluctuations in our inventory supply needs and forecasts of our supply needs;

•costs related to the development of our internal manufacturing capabilities;

•our need to implement additional infrastructure and internal systems;

•our ability to hire additional personnel to support our operations as a public company; and

•the emergence of competing technologies or other adverse market developments.

Our success depends, in part, upon our ability to establish a competitive position in the neuromodulation market by securing broad market acceptance of our 10 kHz Therapy and our Senza product platform for the treatment of chronic pain conditions, as well as our ability to gain market acceptance for other products, such as our SI Joint product portfolio. Any product we develop that achieves regulatory clearance or approval will have to compete for market acceptance and market share. We face significant competition in the United States and internationally, which we believe will intensify as we continue to commercialize in the United States. For example, our major competitors, Medtronic, Boston Scientific and Abbott Laboratories, each have approved neuromodulation systems in at least the United States, Europe and Australia and have been established for several years. In addition to these major competitors, we may also face competition from other emerging competitors and smaller companies with active neuromodulation system development programs that may emerge in the future.

If we are unable to raise, or have access, to sufficient funds when needed, we may be required to delay, reduce, or terminate some or all of our commercial development plans.

The following table sets forth the primary sources and uses of cash for each of the periods presented below:

Net cash used in operating activities was $40.8 million in the six months ended June 30, 2024, compared to $43.8 million in the six months ended June 30, 2023. In the six months ended June 30, 2024, net cash used in operating activities was primarily a result of the net loss recorded during the period of $45.0 million. The cash used in operating activities for the six months ended June 30, 2024 was affected by a decrease in accounts payable and accrued liabilities of $10.3 million and change in fair value of warrants of $23.1 million. These changes were partially offset by the recording of non-cash stock-based compensation expense of $27.3 million, non-cash interest expense of $5.4 million, change in fair value of contingent consideration of $4.4 million and a decrease in accounts receivable of $4.2 million. In the six months ended June 30, 2023, net cash used in operating activities was primarily a result of the net loss recorded during the period of $59.8 million, as well as increases in inventory of $22.6 million, decreases in accounts payable and accrued liabilities of $3.7 million and decreases in other long term liabilities of $2.7 million. These changes were partially offset by the recording of non-cash stock-based compensation expense of

30

$29.7 million, depreciation and amortization of $3.2 million, write-down of inventory of $2.8 million and amortization of operating lease assets of $2.2 million, as well as decreases in accounts receivable of $9.1 million.

We had net proceeds from the maturity of short-term investments of $21.1 million in the six months ended June 30, 2024 and had net purchases of short-term investments of $8.6 million in the six months ended June 30, 2023. We also had purchases of property and equipment of $5.2 million and $4.8 million in the six months ended June 30, 2024 and 2023, respectively.

Cash Provided by (Used in) Financing Activities. Financing activities consisted primarily of tax withholdings for net share settlement and cash received from the issuance of common stock to employees pursuant to the exercise of employee stock options and our employee stock purchase plan. In the six months ended June 30, 2024, we had proceeds from issuance of common stock of $2.7 million, offset by tax withholdings of $1.9 million. Additionally, during the six months ended June 30, 2024, we made a $5.0 million payment related to the contingent consideration. In the six months ended June 30, 2023, we had proceeds from issuance of common stock of $5.2 million, offset by tax withholdings of $3.4 million.

Restructuring

On January 6, 2024, the Company approved a restructuring plan to accelerate its path to profitability that included laying off 63 employees, which represented approximately 5% of the Company’s total number of employees. Operating expenses for the three months ended March 31, 2024 reflected a $5.5 million restructuring charge, consisting of one-time severance and other termination benefit costs. On May 5, 2024, the Company approved additional restructuring steps to further accelerate its path to profitability. Operating expenses for the three months ended June 30, 2024 reflected a $4.6 million restructuring charge, consisting of one-time severance and other termination benefit costs. As of June 30, 2024, substantially all severance and other termination benefit amounts have been paid.

Contractual Obligations and Commitments

We have lease obligations primarily consisting of operating leases for our principal offices, which expire as set forth below, and for our warehouse space. In 2020, we also entered into an operating lease for a manufacturing facility with an expiration date of June 2031.

In March 2015, we entered into a lease agreement for approximately 50,740 square feet of office space located in Redwood City, California for a period beginning in June 2015 and ending in May 2022, with initial annual payments of approximately $2.0 million, increasing to $2.4 million annually in the final year of the lease term. In December 2016, we entered into a first amendment to the lease for an additional approximately 49,980 square feet of office space adjacent to the premises under the original lease (the Expansion Premises) with initial annual payments of $1.2 million, increasing to $2.9 million in the final year of the amended lease term. The lease for the Expansion Premises commenced on June 1, 2018. The first amendment also extends the lease term for the original premises to terminate on the same date as the amended lease, which is May 31, 2025. In April 2024, we entered into an amendment which reduced the total office space to approximately 77,620 square feet, beginning June 1, 2024 through December 31, 2031, with annual payments of $3.0 million, increasing to $5.7 million in the final year of the amended lease term. See Note 6, Commitments and Contingencies, of Notes to Condensed Consolidated Financial Statements for additional information.

In February 2017, we entered into a separate non-cancellable facility lease for warehouse space beginning March 1, 2017 through February 28, 2022, under which we are obligated to pay approximately $0.4 million in lease payments over the term of the lease. In October 2021, we extended our warehouse lease through May 2025, under which we are obligated to pay approximately $0.4 million over the extended term.

In August 2020, we entered into a lease for approximately 35,411 square feet of manufacturing space to begin in April 2021 and to last through June 2031 at a facility in Costa Rica, under which we are obligated to pay approximately $3.9 million in lease payments over the term of the lease. We currently use this facility to build-out certain manufacturing capabilities so that we can vertically integrate the assembly of IPGs, peripherals and various other manufacturing related activities.

We have entered into supply agreements with certain suppliers that require certain minimum annual purchase agreements. As of June 30, 2024, we had minimum annual purchase commitments of $6.3 million due for the remainder of 2024 and $4.9 million due in 2025. In addition, we renegotiated a supplier contract resulting in a one-time $6.0 million fee, expensed as of June 30, 2024. The renegotiation reduced the Company’s future purchase commitments enabling the company to accelerate the move of inventory production to its Costa Rica facility.

31

As of June 30, 2024, our contractual obligations related to the 2025 Notes are payments of interest of $0.5 million due for the remainder of 2024 and payments of interest and principal totaling $38.6 million due in April 2025.

As of June 30, 2024, our contractual obligations related to the Braidwell Term Loan are payments of interest of $5.7 million due for the remainder of 2024, $17.5 million due in 2025, $18.1 million due in 2026 and $20.5 million due in 2027, as well as payments of interest, principal and fees totaling $46.3 million due in 2028 and $232.3 million in 2029.

Off-Balance Sheet Arrangements

Through June 30, 2024, we did not have any relationships with unconsolidated organizations or financial partnerships, such as structured finance or special purpose entities that would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. For information regarding indemnification obligations, refer to Note 6, Commitments and Contingencies, of Notes to Condensed Consolidated Financial Statements within this report.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act refers to controls and procedures that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. Our management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and our management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Our disclosure controls and procedures are designed to provide reasonable assurance of achieving their control objectives.

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures as of June 30, 2024, the end of the period covered by this Quarterly Report. Based upon such evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures were effective at the reasonable assurance level as of such date.

Changes in Internal Control over Financial Reporting

There was no change in our internal control over financial reporting that occurred during the period covered by this Quarterly Report that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Exhibit 10.1

NEVRO CORP.

Non-Employee DIRECTOR COMPENSATION PROGRAM

Non-employee members of the board of directors (the “Board”) of Nevro Corp. (the “Company”) shall be eligible to receive cash and equity compensation as set forth in this Non-Employee Director Compensation Program (this “Program”), as amended by the Board and effective April 7, 2023 (the “Effective Date”). The cash and equity compensation described in this Program shall be paid or be made, as applicable, automatically and without further action of the Board, to each member of the Board who is not an employee of the Company or any parent or subsidiary of the Company (each, a “Non-Employee Director”) who may be eligible to receive such cash or equity compensation, unless such Non-Employee Director declines the receipt of such cash or equity compensation by written notice to the Company. This Program shall remain in effect until it is revised or rescinded by further action of the Board. This Program may be amended, modified or terminated by the Board at any time, without advance notice, in its sole discretion. The terms and conditions of this Program shall supersede any prior cash and/or equity compensation arrangements for service as a member of the Board between the Company and any of its Non-Employee Directors.

1. Cash Compensation.

(a) Annual Retainers. Each Non-Employee Director shall be eligible to receive an annual retainer of $55,000 for service on the Board.

(b) Additional Annual Retainers. In addition, a Non-Employee Director shall receive the following annual retainers:

(i) Non-Executive Chair. To the extent appointed, a Non-Employee Director serving as Non-Executive Chair of the Board shall receive an additional annual retainer of $75,000 for such service.

(ii) Lead Director. To the extent appointed, a Lead Director of the Board shall receive an additional annual retainer of $50,000 for such service.

(iii) Audit Committee. A Non-Employee Director serving as Chairperson of the Audit Committee shall receive an additional annual retainer of $25,000 for such service. A Non-Employee Director serving as a member of the Audit Committee (other than the Chairperson) shall receive an additional annual retainer of $12,000 for such service.

(iv) Compensation Committee. A Non-Employee Director serving as Chairperson of the Compensation Committee shall receive an additional annual retainer of $18,250 for such service. A Non-Employee Director serving as a member of the Compensation Committee (other than the Chairperson) shall receive an additional annual retainer of $8,000 for such service.

(v) Nominating and Corporate Governance Committee. A Non-Employee Director serving as Chairperson of the Nominating and Corporate Governance Committee shall receive an additional annual retainer of $12,000 for such service. A Non-Employee Director serving as a member of the Nominating and Corporate Governance Committee (other than the Chairperson) shall receive an additional annual retainer of $6,000 for such service.

|US-DOCS\141673405.2||

(c) Payment of Retainers. The annual retainers described in Sections 1(a) and 1(b) shall be earned on a quarterly basis based on a calendar quarter and shall be paid by the Company in arrears not later than the fifteenth day following the end of each calendar quarter. In the event a Non-Employee Director does not serve as a Non-Employee Director, or in the applicable positions described in Section 1(b), for an entire calendar quarter, the retainer paid to such Non-Employee Director shall be prorated for the portion of such calendar quarter actually served as a Non-Employee Director, or in such position, as applicable. A director may elect, at his or her option by delivering an election form no later than the 60th day of a calendar quarter, to receive the payment of all or a portion of the Non-Employee Director’s aggregate annual retainer in shares of fully vested common stock issued under the Equity Plan with such election remaining in place unless changed by the Non-Employee Director (the “Stock Payment”). The number of shares shall be calculated by dividing (i) the percentage of the quarterly portion of the annual retainer elected to be received as a Stock Payment (denominated in dollars) by (ii) the per share Fair Market Value (as defined in the Equity Plan) of the Company’s common stock on the last trading day of the applicable fiscal quarter, rounded down to the next whole number of shares. The Stock Payment shall be made on the same date the Company makes the cash payment of the annual retainers.

2. Equity Compensation. Non-Employee Directors shall be granted the equity awards described below. The awards described below shall be granted under and shall be subject to the terms and provisions of the Company’s 2014 Equity Incentive Award Plan or any other applicable Company equity incentive plan then-maintained by the Company (the “Equity Plan”) and shall be evidenced by the execution and delivery of award agreements, including attached exhibits, in substantially the forms previously approved by the Board. All applicable terms of the Equity Plan apply to this Program as if fully set forth herein, and all grants of equity awards hereby are subject in all respects to the terms of the Equity Plan.

(a)Initial Awards. Each Non-Employee Director who is initially elected or appointed to the Board on or after the Effective Date shall automatically be granted, on the date of such initial election or appointment, an award of restricted stock units (an “Initial Award”) with respect to that number of shares of Company common stock calculated by dividing (x) $300,000 by (y) the per share Fair Market Value (as defined in the Equity Plan) of the Company’s common stock on the date of grant, rounded down to the next whole number of shares. No Non-Employee Director shall be granted more than one Initial Award.

(b)Annual Awards. A Non-Employee Director who has served at least six (6) months prior to, and will continue to serve as a Non-Employee Director immediately following, any annual meeting of the Company’s stockholders after the Effective Date (an “Annual Meeting”) shall be automatically granted, on the date of such Annual Meeting, an award of restricted stock units (a “Annual Award”) with respect to that number of shares of Company common stock calculated by dividing (x) $180,000 by (y) the per share Fair Market Value (as defined in the Equity Plan) of the Company’s common stock on the date of grant, rounded down to the next whole number of shares.

(c)Pro-rata Awards. Any Non-Employee Director who is elected or appointed to the Board after January 1, 2019 and prior to the Effective Date, shall be granted, on the Effective Date, an award of restricted stock units (a “Pro-rata Award”) with respect to that number of shares of Company common stock calculated by subtracting the number of shares of Company common stock subject to restricted stock units previously granted to the Non-Employee Director from the quotient obtained by dividing (i) $300,000 by (ii) the per share Fair Market Value of the Company’s common stock on the date of the Non-Employee Director was initially elected or appointed to the Board, rounded down to the next whole number of shares.

2

|US-DOCS\141673405.2||

(d)Vesting. Each Initial Award and Pro-Rata Award shall vest in three (3) equal annual installments on the anniversary of the date the Non-Employee Director was initially elected or appointed to the Board, subject to the Non-Employee Director continuing to provide services to the Company through such vesting date. Each Annual Award shall vest in full upon the earlier of (i) the first anniversary of the date of grant or (ii) the next Annual Meeting following the date of grant, subject to the Non-Employee Director continuing to provide services to the Company through such vesting date. Each Initial Award, Annual Award and Pro-rata Award, along with any other stock options or other equity-based awards held by any Non-Employee Director, shall vest in full immediately prior to the occurrence of a Change in Control (as defined in the Equity Plan), to the extent outstanding at such time.

3. Reimbursements. The Company shall reimburse each Non-Employee Director for all reasonable, documented, out-of-pocket travel and other business expenses incurred by such Non-Employee Director in the performance of his or her duties to the Company in accordance with the Company’s applicable expense reimbursement policies and procedures as in effect from time to time.

Exhibit 10.2

Date:	May 2, 2024
To:	Chris Christoforou
From:	Kevin Thornal
Subject:	Promotion

Dear Chris:

Congratulations! I am pleased to confirm your promotion effective May 15th, 2024.

Here are the details of the new role:

New Title: Chief Operating Officer

Base Salary: Your base salary will be $452,000.16 per year (Exempt - $18,833.34 semi-monthly).

Bonus: Your performance based discretionary cash bonus percentage will now be up to 60% starting May 15, 2024.

Equity: Subject to required corporate approvals, you will be granted a number of Company restricted stock units (“RSUs”) equal to the quotient of (a) $350,000 divided by (b) the average closing price for the Company’s common stock for the thirty (30) day period ending two trading days prior to the date of the grant approval. Such restricted stock units will convert one-for-one into shares of common stock of the Company upon vesting and will vest over a three year period from the Grant Date as follows: (a) one- third of the original number of RSUs on the first anniversary of the Grant Date (the “Anniversary Date”), (b) 1/12th of the original number of RSUs on the three month anniversary of the Anniversary Date (such three month anniversary or any subsequent three month anniversary thereafter referred to as a “Quarterly Anniversary”) and (c) 1/12th of the original number of RSUs on each of the seven subsequent Quarterly Anniversaries, such that all RSUs will have vested on the third anniversary of the Grant Date. The RSUs will be subject to the terms of the Company’s equity plan(s) and a separate RSU agreement to be entered into between you and the Company.

You will also be granted a number of performance stock units (the “PSUs”) equal to (i) $150,000 divided by (ii) the average closing price of the Company’s common stock for the thirty (30) day period ending two trading days prior to the date of the grant approval. The award of the PSUs will be subject to certain performance criteria (the “Criteria”) to be established by the Nevro management. The PSUs will vest fifty percent (50%) on the second anniversary of your grant date (or the first Tuesday of the month following your start date, the “Vesting Commencement Date”) and fifty percent (50%) on the third anniversary of Vesting Commencement Date, in each case subject to (i) your continuous service to the Company through each vesting date and (ii) achievement of the Criteria. The PSUs will, upon vesting and settlement, represent the right to receive a certain number of shares of the Company’s common stock as set forth in a performance stock unit agreement (“PSU Agreement”) to be entered into between you and the Company and as determined pursuant to the Criteria. The PSUs will be granted under the Company’s equity plan(s) and will otherwise be subject to the terms of the Company’s equity plan(s) and the PSU Agreement.

I believe this to be an excellent opportunity for you to continue your contribution to the success of Nevro.

Sincerely,

/s/ Kevin Thornal

Summary of Significant Accounting Policies

1. Summary of Significant Accounting Policies

Basis of Presentation

The accompanying interim condensed consolidated financial statements as of June 30, 2024 and for the three and six months ended June 30, 2024 and 2023, and the related interim information contained within the notes to the financial statements, are unaudited. The unaudited interim condensed consolidated financial statements (the condensed consolidated financial statements) have been prepared in accordance with generally accepted accounting principles in the United States (U.S. GAAP) for interim financial information and on the same basis as the audited financial statements included on the Company’s Annual Report on Form 10-K for the year ended December 31, 2023 (the Annual Report) filed with the Securities and Exchange Commission (SEC) on February 23, 2024. The condensed consolidated financial statements are prepared in U.S. dollars and include the Company’s accounts and those of its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated. In the opinion of management, the accompanying unaudited interim condensed consolidated financial statements contain all adjustments (consisting of normal recurring adjustments) necessary to state fairly the Company’s financial position as of June 30, 2024, the results of its operations for the three and six months ended June 30, 2024 and 2023 and the consolidated statements of cash flows for the six months ended June 30, 2024 and 2023. All such adjustments are of a normal and recurring nature. The interim financial data as of June 30, 2024 is not necessarily indicative of the results to be expected for the year ending December 31, 2024, or for any future period.

The consolidated balance sheet as of December 31, 2023 was derived from the audited financials as of that date. The accompanying condensed consolidated financial statements and related financial information should be read in conjunction with the audited consolidated financial statements and the related notes thereto for the year ended December 31, 2023 included in the Annual Report.

Use of Estimates

The preparation of financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Estimates are based on historical experience, where applicable, and other assumptions believed to be reasonable by management. Actual results may differ from those estimates under different assumptions or conditions.

Foreign Currency Translation

Unrealized foreign exchange gains and losses from the remeasurement of assets and liabilities denominated in currencies other than the functional currency of the reporting entity are recorded in other income (expense), net. Additionally, realized gains and losses resulting from transactions denominated in currencies other than the local currency are recorded in other income (expense), net in the condensed consolidated statements of operations and comprehensive loss. The Company recorded net unrealized and net realized foreign currency transaction gains (losses) during the periods presented as follows (in thousands):

	Three Months Ended						Six Months Ended
	June 30,						June 30,
	2024			2023			2024			2023

Net realized foreign currency gain (loss)		(66	)		(9	)		(388	)		(137	)

New Accounting Pronouncements Not Yet Adopted

In December 2023, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2023-09 (Topic 740): Income Taxes: Improvements to Income Tax Disclosures which expands the existing rules on income tax disclosures. This update requires entities to disclose specific categories in the tax rate reconciliation, provide additional information for reconciling items that meet a quantitative threshold and disclose additional information about income taxes paid on an annual basis. The new disclosure requirements are effective for fiscal years beginning after December 15, 2024. The Company is currently evaluating the impact of adopting ASU 2023-09.

In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures which expands disclosure requirements to require entities to disclose significant segment expenses that are regularly provided to or easily computed from information regularly provided to the chief operating decision maker. This update also requires all annual disclosures currently required by Topic 280 to be disclosed in interim periods. The new disclosure requirements are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. The Company is currently evaluating the impact of adopting ASU 2023-07.

Leases [Abstract]

Lease Accounting

3. Lease Accounting

The Company has operating leases for office space, a manufacturing facility, warehouse, research and development facilities and equipment. Leases with terms of 12 months or less are not recorded on the balance sheet, as the related lease expenses are recognized on a straight-line basis over the lease term. The Company accounts for lease components (such as fixed payments) separately from non-lease components (such as common area expenses).

In April 2024, the Company entered into an amendment to its office space located in Redwood City, California, which reduced the total office space to approximately 78,000 square feet, beginning on June 1, 2024 and ending on December 31, 2031. Pursuant to the lease amendment, the landlord provided the Company with a tenant improvement allowance of up to $4.7 million. The amendment increased the right-of-use asset and lease liability by $15.5 million.

The weighted average lease terms and discounts rates are as follows:

	June 30, 2024	December 31, 2023
Operating Lease Term and Discount Rate
Weighted-average remaining lease term	7.41 years	2.86 years
Weighted-average discount rate	7.0%	7.0%

As of June 30, 2024, the maturity of lease liabilities are as follows (in thousands):

	Operating Leases

Fair Value Disclosures [Abstract]

Fair Value Measurements

4. Fair Value Measurements

Cash Equivalents and Short-Term Investments

The Company’s money market funds are classified within Level 1 of the fair value hierarchy and are valued based on quoted prices in active markets for identical securities. The Company’s short-term investments are comprised of agency bonds, commercial paper, corporate notes and treasury bonds. All short-term investments have been classified within Level 1 or Level 2 of the fair value hierarchy because of the sufficient observable inputs for revaluation. The Company’s Level 2 investments are valued using third-party pricing sources. The pricing services utilize industry-standard valuation models, including both income and market-based approaches, for which all significant inputs are observable, either directly or indirectly, to estimate fair value. These inputs include reported trades of and broker/dealer quotes on the same or similar investments, issuer credit spreads, benchmark investments, prepayment/default

projections based on historical data and other observable inputs. The following table sets forth the Company’s financial instruments that were measured at fair value on a recurring basis by level within the fair value hierarchy (in thousands):

Balance as of June 30, 2024	Level 1		Level 2		Level 3		Total

(i)Included in cash and cash equivalents on the condensed consolidated balance sheets.

(ii)Included in short-term investments on the condensed consolidated balance sheets.

Convertible Senior Notes

As of June 30, 2024 and December 31, 2023, the fair value of the 2.75% convertible senior notes due 2025 (the 2025 Notes) was $35.7 million and $35.6 million, respectively. The fair value was determined on the basis of market prices observable for similar instruments and is considered Level 2 in the fair value hierarchy (See Note 7 for additional information regarding the 2025 Notes).

Warrant Liability

In November 2023, the Company entered into a Credit Agreement and Guaranty (the Braidwell Credit Agreement) with Braidwell LP (together with its affiliates, Braidwell). In connection with the Braidwell Credit Agreement, the Company issued warrants (the Braidwell Warrants) to Braidwell to purchase an aggregate of approximately 2.58 million shares of the Company's common stock.

The Braidwell Warrants are valued using the Black Scholes valuation model and are considered Level 3 in the fair value hierarchy. As of June 30, 2024 and December 31, 2023, the fair value of the Braidwell Warrants was $5.7 million and $28.7 million, respectively. Assumptions for the warrant liability are as follows:

	June 30, 2024	December 31, 2023
Expected term (in years)	5.4	6.0
Expected volatility	53%	53%
Risk-free interest rate	4.08%	3.50%
Dividend yield	0%	0%

Contingent Consideration

In connection with the Company's acquisition of Interventional Pain Technologies, Inc. (Vyrsa) in the fourth quarter of 2023, the Company is subject to certain contingent consideration. Changes in the fair value of the contingent consideration liability for the six months ended June 30, 2024 were as follows (in thousands):

Balance as of December 31, 2023	$	22,093
Change in fair value of contingent consideration		4,431
Contingent consideration payments		(9,804	)
Balance as of June 30, 2024	$	16,720

Upon the achievement of the regulatory approval milestone in the three months ended March 31, 2024, the Company accrued an additional $5.0 million and made contingent consideration payments of $9.8 million.

The regulatory approval milestone and product development milestone consideration are valued using the probability-weighted average discount cash flow model, and the revenue milestone consideration is valued using the Monte Carlo simulation model. The contingent consideration is considered Level 3 in the fair value hierarchy. As of June 30, 2024, the fair value of the contingent consideration related to the product development and revenue milestones were $1.7 million and $14.9 million, respectively. As of December 31, 2023, the fair value of the contingent consideration related to the regulatory approval, product development and revenue milestones were $5.0 million, $1.7 million and $15.5 million, respectively.

Significant unobservable inputs for the contingent consideration are as follows:

Contingent Liability	Fair Value at June 30, 2024	Valuation Technique	Unobservable Input	Range

Cash and cash equivalents include money market funds in the amount of $54.1 million and $82.9 million as of June 30, 2024 and December 31, 2023, respectively. As of June 30, 2024 and December 31, 2023, the Company’s cash equivalents were held at institutions in the United States and include deposits in a money market fund which was unrestricted as to withdrawal or use. The Company also held cash in foreign banks of approximately $13.2 million at June 30, 2024 and $9.4 million at December 31, 2023 that was not insured. The Company has not experienced any losses on its deposits of cash and cash equivalents.

Investments

The Company measures its cash equivalents and short-term investments at fair value, with unrealized gains and losses recorded in accumulated other comprehensive income within stockholders’ equity. The Company regularly reviews its investments and evaluates the current expected credit loss by considering factors such as historical experience, market data, and the near-term

prospects of the investee. The following is a summary of the gross unrealized gains and unrealized losses on the Company’s investment securities, excluding investments in money market funds (in thousands):

Realized gains or losses and other-than-temporary impairments, if any, on available-for-sale securities are reported in other income (expense), net as incurred. The cost of securities sold is determined based on the specific identification method. The amount of realized gains and realized losses on investments recorded for the periods presented has not been material.

The contractual maturities of the Company’s investment securities as of June 30, 2024 were as follows (in thousands):

	Amortized Cost		Fair Value

Finished goods		57,844		51,553
Total inventories	$	126,096	$	118,676

Inventories are stated at the lower of cost or net realizable value. Cost is determined using the standard cost method which approximates the first-in, first-out basis. Net realizable value is determined as the prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. The Company regularly reviews inventory quantities compared to forecasted sales to record a provision for excess and obsolete inventory when appropriate. Inventory write-downs are recorded for excess and obsolete inventory. The Company estimates forecasted sales by considering product acceptance in the marketplace, customer demand, historical sales, product obsolescence and technological innovations.

The Company periodically evaluates the carrying value of inventory on hand for potential excess amount over demand using the same lower of cost or net realizable value approach as that has been used to value the inventory. The Company also periodically evaluates inventory quantities in consideration of actual loss experience. As a result of these evaluations, there was an immaterial change to the carrying value of inventory recognized for the three months ended June 30, 2024 and for the three months ended June 30, 2023, the Company recognized a write-down of $1.6 million. For the six months ended June 30, 2024 and 2023, the Company had write-downs of $0.7 million and $2.8 million, respectively.

Commitments and Contingencies

Operating Leases

In March 2015, the Company entered into a lease agreement for approximately 50,000 square feet of office space located in Redwood City, California for a period beginning on June 30, 2015 and ending in May 2022, with initial annual payments of approximately $2.0 million, increasing to $2.4 million annually during the final year of the lease term. In December 2016, the Company entered into a first amendment to the lease for an additional approximately 50,000 square feet of office space adjacent to the premises under the original lease (the Expansion Premises), with initial annual payments of $1.2 million, increasing to $2.9 million in the final year of the amended lease term. The lease for the Expansion Premises commenced on June 1, 2018, and includes an expiration date of May 31, 2025. The first amendment extended the lease term for the original premises to terminate on the same date as the Expansion Premises. In April 2024, the Company entered into a second amendment which reduced the total office space to approximately 78,000 square feet, beginning on June 1, 2024 and ending on December 31, 2031, with initial annual payments of approximately $3.0 million, increasing to approximately $5.7 million during the final year of the lease term. Pursuant to the second lease amendment, the landlord provided the Company with a tenant improvement allowance of up to $4.7 million.

The Company entered into a separate non-cancellable facility lease for warehouse space beginning on March 1, 2017 through February 28, 2022, under which it is obligated to pay approximately $0.4 million in lease payments over the term of the lease. In October 2021, the Company entered into a first amendment of the warehouse lease, which extends the lease term to terminate on May 31, 2025 and under which the Company is obligated to pay approximately $0.4 million over the term of the extension period.

In August 2020, the Company entered into a lease for approximately 35,411 square feet of space for a manufacturing facility in Costa Rica to begin in April 2021 and to last through June 2031, under which it is obligated to pay approximately $3.9 million in lease payments over the term of the lease. On the commencement date in April 2021, the Company classified and measured the lease, resulting in the recording of operating assets of $2.9 million and operating lease liabilities of $2.9 million.

See Note 3 for further discussion on Lease Accounting.

Warranty Obligations

The Company provides a limited one- to five-year warranty and warrants that its products will operate substantially in conformity with product specifications. The Company records an estimate for the provision for warranty claims in cost of revenue when the related revenues are recognized. This estimate is based on historical and anticipated rates of warranty claims, the cost per claim and the number of units sold. The Company regularly assesses the adequacy of its recorded warranty obligations and adjusts the amounts as necessary. Activities related to warranty obligations were as follows (in thousands):

	Three Months Ended						Six Months Ended

Ending balance	$	2,200		$	1,349		$	2,200		$	1,349

Supply Agreements

The Company has entered into supply agreements with certain suppliers that require certain minimum annual purchase agreements. As of June 30, 2024, the Company had minimum annual purchase commitments of $6.3 million due for the remainder of 2024 and $4.9 million due in 2025. In addition, the Company renegotiated a supplier contract resulting in a one-time $6.0 million fee, recorded in accrued liabilities and expensed to cost of revenue as of June 30, 2024. The renegotiation reduced the Company’s future purchase commitments enabling the company to accelerate the move of inventory production to its Costa Rica facility.

Contingencies

From time to time, the Company may have certain contingent liabilities that arise in the ordinary course of business activities related to, for example, employment matters and patent issues. 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. When determining the estimated loss or range of loss, significant judgment is required.

Indemnification

The Company enters into standard indemnification arrangements in the ordinary course of business. Pursuant to these arrangements, the Company indemnifies, holds harmless and agrees to reimburse the indemnified parties for losses suffered or incurred by the indemnified party, in connection with any trade secret, copyright, patent or other intellectual property infringement claim by any third-party with respect to the Company’s technology. The term of these indemnification agreements is generally perpetual. The maximum potential amount of future payments the Company could be required to make under these agreements is not determinable because it involves claims that may be made against the Company in the future, but have not yet been made.

The Company has entered into indemnification agreements with its directors and officers that may require the Company to indemnify its directors and officers against liabilities that may arise by reason of their status or service as directors or officers, other than liabilities arising from willful misconduct of the individual. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is unlimited; however, the Company has director and officer insurance coverage that reduces the Company’s exposure and enables the Company to recover a portion of any future amounts paid. The Company believes the estimated fair value of these indemnification agreements in excess of applicable insurance coverage is minimal.

Legal Matters

The Company is and may from time to time continue to be involved in various legal proceedings to defend its intellectual property, including several pending European patent oppositions at the European Patent Office (EPO) initiated by the Company’s competitors Medtronic and Boston Scientific. In addition, the Company is and may from time to time also be involved in various legal proceedings, such as employment matters, product liability matters, and professional liability matters, which the Company does not deem to be material to its business and condensed consolidated financial statements at this stage.

Flathead Partners Litigation/Arbitration

On July 15, 2022, the Company filed a lawsuit in the U.S. District Court for the Northern District of California for breach of contract against Flathead Partners, LLC, the Mayo Foundation for Medical Education and Research, and Mayo Clinic Ventures (herein referred to as “Flathead Partners”). The Company’s suit alleged that Flathead Partners breached the 2006 license agreement between the Company and the Mayo Clinic (referred to in the Company’s 10-K filing as the “Mayo License”), when Flathead Partners unilaterally asserted control of pending U.S. Patent Application 16/286,389 (the “’389 Application”), which is subject to the Mayo License. The suit sought to enjoin the Flathead Partners from taking any action at the U.S. Patent Office with respect to the ‘389 Application, and to thereafter engage in an arbitration as called for in the Mayo License. On July 27, 2022, the Flathead Partners agreed to enter into an arbitration to determine which party shall have control of prosecution of the ‘389 Application, and whether there are ongoing royalty obligations under the Mayo License. Therefore, Nevro dismissed the lawsuit in the Northern District of California. The parties then engaged in an arbitration. An arbitration hearing was held during the week of September 11, 2023, and a ruling was issued on April 8, 2024 requiring that Flathead Partners transfer back to the Company the power to control and direct prosecution of the ‘389 Application and its patent family. The April 8, 2024 ruling also concluded that Nevro did not owe Flathead Partners royalties under the Mayo License. More specifically, the Arbitrator found that Flathead Partners had breached the Mayo License, and that the Company had not breached the Mayo License. The Arbitrator awarded the Company (i) $0.2 million in damages, paid by Flathead Partners in May 2024; (ii) the Company’s attorneys’ fees and costs for the Northern District of California litigation (a final amount to be awarded after accounting submissions in August 2024); and (iii) prejudgment interest at a rate of 10%, with prejudgment interest running from June 1, 2022 (a final amount to be calculated in August 2024).

Civil Investigative Demand

In December 2022, the Company received a civil investigative demand (CID) pursuant to the federal False Claims Act from the United States Attorney’s Office for the Northern District of California seeking information relating to the Company’s spinal cord stimulation system (SCS System). The CID primarily relates to marketing, promotion and billing practices, not the therapeutic or safety attributes of the Company’s SCS System. The Company maintains rigorous policies and procedures designed to promote compliance with the federal False Claims Act and other regulatory requirements, and is cooperating in this matter and providing the requested information.

2025 Notes and Convertible Note Hedge and Warrant Transactions

During the three months ended June 30, 2024, the conditions allowing holders of the 2025 Notes to convert have not been met.

Credit Agreement with Braidwell LP

The Braidwell Credit Agreement provides for a term loan facility in the amount of $200.0 million, which was funded in its entirety in November 2023. Loans borrowed pursuant to the Braidwell Credit Agreement (the Braidwell Term Loans) bear interest at a rate per annum equal to Term Secured Overnight Financing Rate (as defined in the Braidwell Credit Agreement and with a floor of 3.50%) plus 5.25%. At the option of the Company, a portion of the interest payable on the Braidwell Term Loans equal to (i) (a) on or prior to the first anniversary of the Closing Date (as defined in the Braidwell Credit Agreement), 5.25%, (b) following the first anniversary of the Closing Date and on or prior to the third anniversary of the Closing Date, 2.50% and (c) following the third anniversary of the Closing Date, 1.50%, may be paid in-kind rather than in cash. The portion of the interest payable that the Company elects to be paid-in-kind results in an increase to the principal of the Braidwell Term Loans, which for the three and six months ended June 30, 2024 was $2.8 million and $5.4 million, respectively. The Braidwell Term Loans do not amortize, and have a maturity date of November 30, 2029. As of June 30, 2024, the Company was in compliance with covenants under the Braidwell Credit Agreement.

Stock-Based Compensation

9. Stock-Based Compensation

The Company accounts for stock-based compensation arrangements with employees in accordance with Accounting Standards Codification (ASC) 718, Compensation—Stock Compensation. ASC 718 requires the recognition of compensation expense, using a fair value-based method, for costs related to all share-based payments including stock options. The Company estimates forfeitures expected to occur to determine the amount of compensation cost recognized in each period.

In addition to restricted stock units, the Company grants performance stock units (PSUs) to certain members of the management team. These PSUs vest over a three-year period, subject to continued service, and are based on (1) the total shareholder return (TSR) of the Company’s common stock price compared to the S&P Healthcare Equipment Select Industry Index (the Index) over a two-year period or (2) specific revenue targets over a two-year performance period. Additionally, in 2022, the Company made PSU grants to its then CEO that included attainment criteria that required the Company's stock price to reach certain pre-specified stock prices. Since TSR and stock price attainment are considered market conditions, the PSUs based on TSR and stock price attainment have fair values that are determined at the grant date using the Monte Carlo simulation model, with the recorded expense based on fair value. Since revenue targets are considered performance conditions, the PSUs based on revenue targets have a fair value that is equal to the closing stock price on the grant date, with the recorded expense based on the fair value and the probability of achievement, which is reassessed at each reporting period.

The PSU grant activity is as follows:

Basic and Diluted Net Income (Loss) Per Share

10. Basic and Diluted Net Income (Loss) Per Share

Basic net loss per share is computed by dividing the net loss by the weighted average number of common shares outstanding for the period. Diluted net income (loss) per share is computed by dividing the net income (loss) by the weighted average number of common shares and dilutive common stock equivalents outstanding for the period, if inclusion of these is dilutive. The Company uses the if-converted method and presumes share settlement for its 2025 Notes when calculating the dilutive effect of these notes. In connection with the offerings of the convertible senior notes, the Company entered into convertible note hedges and warrants. However, the convertible note hedges are not included when calculating potentially dilutive shares since their effect is always anti-dilutive. Warrants were considered anti-dilutive to the extent that their strike price were above the Company's average share price during the period.

The following table summarizes the computation of basic and diluted net loss per share (in thousands, except share and per share data):

New Accounting Pronouncements Not Yet Adopted

In December 2023, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2023-09 (Topic 740): Income Taxes: Improvements to Income Tax Disclosures which expands the existing rules on income tax disclosures. This update requires entities to disclose specific categories in the tax rate reconciliation, provide additional information for reconciling items that meet a quantitative threshold and disclose additional information about income taxes paid on an annual basis. The new disclosure requirements are effective for fiscal years beginning after December 15, 2024. The Company is currently evaluating the impact of adopting ASU 2023-09.

In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures which expands disclosure requirements to require entities to disclose significant segment expenses that are regularly provided to or easily computed from information regularly provided to the chief operating decision maker. This update also requires all annual disclosures currently required by Topic 280 to be disclosed in interim periods. The new disclosure requirements are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. The Company is currently evaluating the impact of adopting ASU 2023-07.

Cash and Cash Equivalents

Cash and Cash Equivalents

The Company considers all highly-liquid investments purchased with an original maturity of three months or less at the date of purchase to be cash equivalents. Cash and cash equivalents include money market funds in the amount of $54.1 million and $82.9 million as of June 30, 2024 and December 31, 2023, respectively. As of June 30, 2024 and December 31, 2023, the Company’s cash equivalents were held at institutions in the United States and include deposits in a money market fund which was unrestricted as to withdrawal or use. The Company also held cash in foreign banks of approximately $13.2 million at June 30, 2024 and $9.4 million at December 31, 2023 that was not insured. The Company has not experienced any losses on its deposits of cash and cash equivalents.

Inventories

Inventories

Inventories are stated at the lower of cost or net realizable value. Cost is determined using the standard cost method which approximates the first-in, first-out basis. Net realizable value is determined as the prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. The Company regularly reviews inventory quantities compared to forecasted sales to record a provision for excess and obsolete inventory when appropriate. Inventory write-downs are recorded for excess and obsolete inventory. The Company estimates forecasted sales by considering product acceptance in the marketplace, customer demand, historical sales, product obsolescence and technological innovations.

The Company periodically evaluates the carrying value of inventory on hand for potential excess amount over demand using the same lower of cost or net realizable value approach as that has been used to value the inventory. The Company also periodically evaluates inventory quantities in consideration of actual loss experience. As a result of these evaluations, there was an immaterial change to the carrying value of inventory recognized for the three months ended June 30, 2024 and for the three months ended June 30, 2023, the Company recognized a write-down of $1.6 million. For the six months ended June 30, 2024 and 2023, the Company had write-downs of $0.7 million and $2.8 million, respectively.
