Income taxes	6 Months Ended
Income taxes	Jun. 30, 2026
Income Tax Disclosure [Abstract]
Income taxes	Income taxes As of June 30, 2026 and December 31, 2025, a valuation allowance was recorded against all deferred tax assets due to our cumulative net loss position. Provision for income taxes for the three months ended June 30, 2026 was $3,000 and benefit for income taxes for the three months ended June 30, 2025 was $3,000. Provision for income taxes for the six months ended June 30, 2026 was $4,000 and benefit for income taxes for the six months ended June 30, 2025 was $8,000. As of December 31, 2025, we had federal and state net operating loss carryforwards (“NOLs”) of approximately $483.7 million and $9.7 million, respectively. The federal NOLs began expiring in 2021 and the state NOLs began expiring in 2020. As of December 31, 2025, we had federal and state tax credit carryforwards of approximately $10.3 million and $1.9 million, respectively. The federal tax credit carryforwards began expiring in 2021 and the state tax credits will begin expiring in 2028. Utilization of NOLs may be subject to an annual limitation due to the ownership change limitations provided by Section 382 of the Internal Revenue Code of 1986, as amended, and similar state provisions. We have not performed a detailed analysis to determine whether an ownership change has occurred. Such a change of ownership would limit our utilization of the NOLs and could be triggered by subsequent sales of securities by us or our stockholders. On July 4, 2025, the One Big Beautiful Bill Act (“OBBBA”) was enacted in the U.S. The OBBBA includes significant tax-related provisions, such as the permanent extension of certain expiring provisions of the Tax Cuts and Jobs Act, modifications to the international tax framework, and the restoration of favorable tax treatment for certain business provisions, including the capitalization of certain R&D costs. The legislation has multiple effective dates, with certain provisions effective in 2026 and others implemented through 2028. The impacts of the OBBBA were taken into account in our provision for income taxes for fiscal year 2025. Because a valuation allowance has been recorded against all deferred tax assets, the impacts of the OBBBA were not material to our consolidated financial statements or related disclosures.

Earnings Per Share [Abstract]

Loss Per Share

Basic and diluted net loss per share attributable to common stockholders was calculated for the periods indicated (in thousands, except share and per share data):

Net loss per share attributable to common stockholders — basic and diluted	$	(0.53)	$	(0.57)	$	(1.03)	$	(1.10)

Our potentially dilutive securities, which include stock options, RSUs, PSUs, and warrants to purchase shares of common stock, have been excluded from the computation of diluted net loss per share attributable to common stockholders, as the effect would be to reduce the net loss per share attributable to common stockholders. Therefore, the weighted average number of common shares outstanding used to calculate both basic and diluted net loss per share attributable to common stockholders is the same. We excluded the following potential common shares, presented based on amounts outstanding at each period end, from the computation of diluted net loss per share attributable to common stockholders for the periods indicated because including them would have had an anti-dilutive effect:

Accounting Policies [Abstract]
Statement presentation	Statement presentation and basis of consolidation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) applicable to interim financial statements. In the Company’s opinion, the accompanying unaudited condensed consolidated financial statements reflect all adjustments necessary for a fair presentation of the Company’s statements of financial position, results of operations, and cash flows for the periods presented. The results of operations for the interim periods are not necessarily indicative of results that may be expected for the fiscal year as a whole or any other future period. The condensed consolidated financial statements include the accounts of CVRx, Inc. and its wholly owned subsidiary, CVRx Switzerland LLC. All intercompany balances and transactions have been eliminated in consolidation.

The condensed consolidated financial statements include the accounts of CVRx, Inc. and its wholly owned subsidiary, CVRx Switzerland LLC. All intercompany balances and transactions have been eliminated in consolidation.
JOBS Act accounting election	JOBS Act accounting election We are an emerging growth company under the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). As a result, we have elected to take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies.
Use of estimates	Use of estimates Preparation of the condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and the accompanying notes. Actual results could differ from those estimates.
Cash and cash equivalents	Cash and cash equivalents Cash and cash equivalents include highly liquid investments with an original maturity of three months or less. As of June 30, 2026 and December 31, 2025, cash equivalents consisted of money market funds, which are stated at cost and approximate fair value. Additionally, as of June 30, 2026 and December 31, 2025, a majority of our cash and cash equivalents were maintained with two financial institutions in the U.S., and our current deposits were in excess of insured limits.
Accounts Receivable	Accounts Receivable Trade accounts receivable are recorded at the invoiced amount and do not bear interest. Customer credit terms are established prior to shipment with the standard generally being net 30 days. We evaluate the collectability of our accounts receivable based on known collection risks and historical experience. In circumstances where we are aware of a specific customer's inability to meet its financial obligations to us, we record a specific allowance for bad debts against amounts due to reduce the carrying amount of accounts receivable to the amount we reasonably believe will be collected.
Inventory	Inventory Inventory is stated at the lower of cost or net realizable value, with cost determined on a first-in, first-out basis. We regularly review inventory quantities based on actual loss experiences, projected future demand and remaining shelf life to record a provision for excess and obsolete inventory when appropriate.
Leases	Leases Operating leases are included in operating lease right-of-use (“ROU”) asset, accrued expenses, and operating lease liability – non-current portion in our balance sheets. ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. We used the incremental borrowing rate based on information readily available at the time of recognition to determine the present value of the lease payments. The determination of our incremental borrowing rate requires management judgment based on information available at lease commencement.
Revenue recognition	Revenue recognition We sell our products primarily through a direct sales force and to a lesser extent through a combination of sales agents and independent distributors. Our revenue consists primarily of the sale of our Barostim, which consists of two implantable components: a pulse generator and a stimulation lead. Under Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts with Customers (“ASC 606”), revenue is recognized when a customer obtains control of promised goods or services, in an amount that reflects the consideration that the entity expects to receive in exchange for those goods or services. To determine revenue recognition for arrangements that an entity determines are within the scope of ASC 606, we perform the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a performance obligation. We only apply the five-step model to contracts when it is probable that we will collect the consideration we are entitled to in exchange for the goods or services it transfers to the customer. We recognize net revenue on product sales, adjusted for any applicable estimates of variable consideration, when the customer obtains control of our product, which generally occurs at a point in time upon delivery based on the contractual shipping terms of a contract. Our contracts have a single performance obligation, and our payment terms with customers are generally between 30 and 90 days. Variable consideration related to certain customer rebates is estimated based on the amounts expected to be paid under the agreement with the customer.
Stock-Based Compensation	Stock-Based Compensation We recognize equity-based compensation expense for awards of equity instruments to employees and non-employees based on the grant date fair value of those awards in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Topic 718, Compensation—Stock Compensation (“ASC 718”). ASC 718 requires all equity-based compensation awards to employees and non-employee directors, including grants of restricted shares and stock options, to be recognized as expense in the statements of operations and comprehensive loss based on their grant date fair values. We estimate the grant date fair value of stock options using the Black-Scholes option pricing model, and the fair value of restricted stock units (“RSUs”) and performance stock units (“PSUs”) are equal to the closing price of our common stock on the grant date. We account for forfeitures as they occur. We expense the fair value of our equity-based compensation awards granted to employees on a straight-line basis over the associated service period, which is generally the period in which the related services are received for stock options and RSUs, and the performance period and any additional service period based on the probability of achieving the performance objectives for PSUs.
Recent accounting pronouncements	Recent accounting pronouncements In November 2024, the FASB issued ASU 2024-03, Income Statement — Reporting Comprehensive Income (Subtopic 220-40): Disaggregation of Income Statement Expenses. The amendments require public business entities to provide enhanced disclosures related to the disaggregation of income statement expenses, including additional quantitative and qualitative information about the nature of expenses presented within relevant expense captions. The guidance is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027, with early adoption permitted. We have not yet adopted ASU 2024-03 and are in the process of evaluating the impact of the guidance on our consolidated financial statements. While the amendments will require additional disclosures and may require changes to internal data aggregation and reporting processes, we do not expect adoption to have a material impact on its results of operations, financial position, or cash flows.

Leases [Abstract]

Leases

We lease 35,183 square feet of office space in Minneapolis, Minnesota, which houses our principal executive offices and our manufacturing facility. We lease this space under an operating lease agreement that commenced December 1, 2008 and was scheduled to expire August 31, 2024. On April 21, 2023, we extended the operating lease for our office space in Minneapolis, Minnesota for an additional 49 consecutive months through August 31, 2028. On November 7, 2023, we expanded our existing office space with the addition of 7,615 square feet of property adjacent to our principal executive offices and our manufacturing facility. On May 20, 2025, we further increased our office space by leasing an additional 3,678 square feet of the contiguous property. The term on this expanded property is for 40 consecutive months, which will run concurrently with the term on the existing lease. We intend to add new facilities as we grow, and we believe that suitable additional or substitute space will be available as needed to accommodate any such expansion of our operations. Our operating lease agreement includes an option to renew for one additional period of three years. The exercise of the lease renewal option is at our sole discretion and was not included in the lease term for the calculation of the ROU asset and lease liability, as it is not reasonably certain of exercise.

In addition to base rent, we also pay our proportionate share of operating expenses, as defined in the lease. These payments are made monthly and are adjusted annually to reflect actual charges incurred for operating expenses, such as common area maintenance, taxes, and insurance.

The following table presents the lease balances within the condensed consolidated balance sheets:


(in thousands)	June 30, 2026		December 31, 2025
Right-of-use assets:
Operating lease right-of-use asset	$	708	$	878
Operating lease liabilities:
Accrued expenses	371		352
Operating lease liability, non-current portion	448		638
Total operating lease liabilities	$	819	$	990

Maturities of our lease liability for our operating lease are as follows as of June 30, 2026:


(in thousands)	June 30, 2026
2026	$	207
2027	424
2028	253
Total undiscounted lease payments	884
Less: imputed interest	(65)
Present value of lease liability	$	819

As of June 30, 2026, the remaining lease term was 2.2 years, and the weighted average discount rate was 7.1%. The operating cash outflows from our operating lease were $0.3 million for each of the six months ended June 30, 2026 and 2025.

Segment Reporting [Abstract]

Segment, geographic information, and revenue disaggregation

We have determined that we have a single reportable and operating segment structure. We have one business activity and there are no segment managers who are held accountable for operations, operating results, or plans for levels or components below the consolidated unit level. Our chief operating decision maker is our Chief Executive Officer. Our Chief Executive Officer evaluates performance based primarily on revenue in the geographic locations in which we operate and consolidated net loss. The Chief Executive Officer reviews financial information presented on a consolidated basis, including consolidated net loss, accompanied by information about revenue by geographic region, for purposes of allocating resources and evaluating financial performance. Further, the financial information on expenses provided to the Chief Executive Officer is presented on a consolidated basis, as reported in the condensed consolidated statements of operations and comprehensive loss in this Quarterly Report on Form 10-Q.

We derive all our revenues from sales to customers in Europe and the U.S. The following table provides revenue by country for each location accounting for more than 10% of the total revenue for the periods indicated (in thousands):


	Three months ended June 30,				Six months ended June 30,
	2026		2025		2026		2025
U.S.	$	14,775	$	12,243	$	28,425	$	23,444
Other countries	930		1,346		2,049		2,493
	$	15,705	$	13,589	$	30,474	$	25,937

As of June 30, 2026 and December 31, 2025, substantially all our long-lived assets were located in the U.S.

Share-Based Payment Arrangement [Abstract]

Stock-based compensation

Summary of plans and activity

In June 2001, our Board of Directors and stockholders established the 2001 Stock Incentive Award Plan (“2001 Plan”). Under the 2001 Plan, as amended, 2,674,749 shares of common stock had been reserved for the issuance of incentive stock options granted to employees, non-employee directors, consultants, or independent contractors. Options granted under the 2001 Plan have vesting terms that range from the date of grant to four years and expire within a maximum term of 10 years from the grant date.

In 2021, our Board of Directors and stockholders established the 2021 Equity Incentive Plan (“2021 Plan”). The number of shares of common stock initially reserved for issuance under the 2021 Plan was 1,854,490 newly reserved shares in addition to the 600,737 shares that remained available for issuance under the 2001 Plan. The shares available for issuance under the 2021 Plan automatically increase on the first day of each year, commencing January 1, 2022, and ending on (and including) January 1, 2031, in an amount equal to 5% of the total number of shares of our common stock outstanding on the last day of the calendar month before the date of each automatic increase, or such lesser number of shares as determined by the Board of Directors. The annual increase resulted in an additional 1,315,580 shares being reserved for issuance under the 2021 Plan as of January 1, 2026. The 2021 Plan provides for the issuance of stock options, stock appreciation rights,

restricted stock awards, stock unit awards and other stock-based awards and cash incentive awards to employees, consultants and non-employee directors of the Company and its subsidiaries. Awards granted under the 2021 Plan will have such vesting schedules and other terms as determined by the Compensation Committee and stock options and stock appreciation rights have a maximum term of 10 years from the grant date. No further awards can be granted under the 2001 Plan following the adoption of the 2021 Plan.

As of June 30, 2026, there were 463,119 shares available for future issuance under the 2021 Plan, based on awards outstanding and reserved at target levels for PSUs. In connection with the PSUs granted during 2026, we evaluated the number of shares that could be issued assuming maximum achievement of the applicable performance conditions. If PSUs are reserved at the maximum payout level, the number of shares subject to outstanding awards could exceed the shares available under the plan as of June 30, 2026. We expect that we will have sufficient shares available for issuance under the 2021 Plan to satisfy these awards as a result of future automatic annual increases pursuant to the terms of the plan prior to the end of the performance period.

Stock Options

Options are granted at exercise prices not less than the fair market value of our common stock on the date of grant. Prior to our initial public offering (the “IPO”), the fair market value of our common stock was determined by our Board of Directors, and following our IPO, the fair market value of our common stock is based on the closing price of our common stock on the date of grant.

During the years 2008 through the IPO, the Board of Directors authorized the grant of stock options for the purchase of shares of common stock to the employers of certain non-employee directors. The options were not granted under the 2001 Plan or the 2021 Plan, but terms are substantially the same as our standard form of option agreement for non-employee directors as they have an exercise price not less than the fair market value on the grant date and vest over 48 months from the date of grant.

The following is a summary of stock option activity:


	Number of Options	Weighted Average Exercise Price		Aggregate Intrinsic Value
				(in thousands)
Balance as of December 31, 2025	5,834,448	$	11.96	$	2,459
Granted	1,217,444	7.83
Cancelled / Forfeited	(241,342)	13.63
Exercised	(42,881)	1.58
Balance as of June 30, 2026	6,767,669	$	11.23	$	620
Options exercisable as of June 30, 2026	4,181,115	$	11.48	$	620

As of June 30, 2026, stock options outstanding included 4,363 options that were not granted under the 2001 Plan or the 2021 Plan. For options outstanding as of June 30, 2026, the weighted average remaining contractual life was 6.8 years. For options exercisable as of June 30, 2026, the weighted average remaining contractual life was 5.5 years. As of June 30, 2026, unrecognized compensation expense related to unvested stock-based compensation arrangements for stock options was $20.1 million. As of June 30, 2026, the related weighted average period over which the expense is expected to be recognized is approximately 2.7 years.

Restricted Stock Units

RSUs are share awards that entitle the holder to receive freely tradable shares of our common stock upon vesting. The RSUs cannot be transferred and the awards are subject to forfeiture if the holder’s service terminates prior to vesting other than for death, disability, or other qualifying terminations.

The following is a summary of RSU activity:


	Number of RSUs	Weighted Average Grant Date Fair Value		Aggregate Intrinsic Value
				(in thousands)
Unvested Balance as of December 31, 2025	383,268	$	12.11	$	2,721
Granted	743,430	7.76
Vested	(82,147)	12.84
Cancelled / Forfeited	(22,020)	10.28
Unvested Balance as of June 30, 2026	1,022,531	$	8.92	$	5,256

The aggregate intrinsic value of unvested RSUs is based on our closing stock price on the last trading day of the period. 82,147 RSUs were vested as of June 30, 2026. As of June 30, 2026, the unrecognized compensation expense related to unvested stock-based compensation arrangements for RSUs was $8.3 million. As of June 30, 2026, the related weighted average period over which the expense is expected to be recognized is approximately 3.3 years.

Performance Stock Units

We grant PSUs to officers and key employees. The number of PSUs that will ultimately be earned is based on our performance relative to pre-established performance goals for the respective performance period. The expense is recorded on a straight-line basis over the requisite performance and service periods based on an estimate of the number of PSUs expected to vest. Management expectations related to the achievement of the performance goals associated with PSU grants are assessed each reporting period. The number of PSUs earned at the end of the performance period ranges from 0% to 200% of the number of PSU’s granted. The PSUs cannot be transferred and the awards are subject to forfeiture if the holder’s service terminates prior to vesting other than for death, disability, or other qualifying terminations.

If the performance conditions are not met or not expected to be met, any compensation expense recognized associated with the grant will be reversed.

The following is a summary of PSU activity:


	Number of PSUs	Weighted Average Grant Date Fair Value		Aggregate Intrinsic Value
				(in thousands)
Unvested Balance as of December 31, 2025	—	$	—	$	—
Granted	602,000	8.16
Vested	—	—
Cancelled / Forfeited	—	—
Unvested Balance as of June 30, 2026	602,000	$	8.16	$	3,094

The aggregate intrinsic value of unvested PSUs is based on our closing stock price on the last trading day of the period. As of June 30, 2026, there was $4.2 million of unrecognized stock-based compensation expense related to outstanding PSUs that is expected to be recognized over a weighted-average period of 2.0 years.

Employee Stock Purchase Plan

Our Board of Directors and stockholders also established an Employee Stock Purchase Plan (the “ESPP”). The number of shares of common stock initially reserved for issuance under the ESPP was 278,170. The shares available for issuance under the ESPP automatically increase on the first day of each year, commencing January 1, 2022, and ending on (and including) January 1, 2031, in an amount equal to 1% of the total number of shares of our common stock outstanding on the last day of the calendar month before the date of each automatic increase, or such lesser number of shares as determined by the Board of Directors. No annual

increase was made to the shares reserved for issuance under the ESPP as of January 1, 2026. The ESPP permits certain of our U.S. employees to purchase shares of our common stock at a price per share not less than 85% of the lower of (i) the closing market price per share of our common stock on the first day of the applicable purchase period or (ii) the closing market price per share of our common stock on the purchase date at the end of the applicable six-month purchase period. For the six months ended June 30, 2026, 102,808 shares of common stock were purchased under the ESPP for $0.5 million of employee contributions. As of June 30, 2026, there were 634,588 shares available for issuance under the ESPP.

Stock-based compensation expense

We use the Black-Scholes option pricing model to determine the fair value of stock options and ESPP purchase rights on the grant date. The fair values of RSUs and PSUs are determined based on the closing stock price of our common stock on the grant date. We measure stock-based compensation expense based on the grant date fair value of the award and recognize compensation expense over the requisite service period, which is generally the vesting period for stock options, RSUs, and PSUs, and the offering period for ESPP purchase rights. The amount of stock-based compensation expense recognized for stock option, RSU, and PSU awards during a period is based on the portion of the awards that are ultimately expected to vest. The amount of stock-based compensation expense recognized for ESPP purchase rights during a period is based on the estimated purchase rights as of the grant date. We account for forfeitures as they occur.

The following table provides the weighted average fair value of options granted to employees and the related assumptions used in the Black-Scholes option pricing model for the six months ended June 30, 2026 and 2025:


	June 30,
	2026			2025
Weighted average fair value of options granted	$	6.28		$	9.52
Expected term (in years) — non-officer employees	5.5 to 6.1			5.5 to 6.1
Expected term (in years) — officer employees	6.1			6.1
Expected volatility	98.2% to 99.1%			95.0% to 103.1%
Expected dividend yield	—		%	—		%
Risk-free interest rate	3.72% to 4.32%			3.93% to 4.47%

The following table provides the weighted average fair value of ESPP purchase rights and the related assumptions used in the Black-Scholes option pricing model for the six months ended June 30, 2026 and 2025:


	June 30,
	2026			2025
Weighted average fair value per ESPP purchase right	$	1.63		$	2.83
Expected term (in years)	0.5			0.5
Expected volatility	61.1%			112.3%
Expected dividend yield	—		%	—		%
Risk-free interest rate	3.58%			4.25%

We review these assumptions on a periodic basis and adjust them, as necessary. We utilize the simplified method to develop the estimate of the expected term for stock option awards and ESPP purchase rights. The expected volatility is based upon our historical stock price. The expected dividend yield is assumed to be zero, as we have never paid dividends and have no current plans to do so. The risk-free interest rate is based on the yield on U.S. Treasury securities for a period approximating the expected term of the options being valued.

The following table presents the components and classification of stock-based compensation expense for the periods indicated:

Accounting Policies [Abstract]
Summary of significant accounting policies	Summary of significant accounting policies Statement presentation and basis of consolidation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) applicable to interim financial statements. In the Company’s opinion, the accompanying unaudited condensed consolidated financial statements reflect all adjustments necessary for a fair presentation of the Company’s statements of financial position, results of operations, and cash flows for the periods presented. The results of operations for the interim periods are not necessarily indicative of results that may be expected for the fiscal year as a whole or any other future period. The condensed consolidated financial statements include the accounts of CVRx, Inc. and its wholly owned subsidiary, CVRx Switzerland LLC. All intercompany balances and transactions have been eliminated in consolidation. JOBS Act accounting election We are an emerging growth company under the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). As a result, we have elected to take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies. Use of estimates Preparation of the condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and the accompanying notes. Actual results could differ from those estimates. Cash and cash equivalents Cash and cash equivalents include highly liquid investments with an original maturity of three months or less. As of June 30, 2026 and December 31, 2025, cash equivalents consisted of money market funds, which are stated at cost and approximate fair value. Additionally, as of June 30, 2026 and December 31, 2025, a majority of our cash and cash equivalents were maintained with two financial institutions in the U.S., and our current deposits were in excess of insured limits. Accounts Receivable Trade accounts receivable are recorded at the invoiced amount and do not bear interest. Customer credit terms are established prior to shipment with the standard generally being net 30 days. We evaluate the collectability of our accounts receivable based on known collection risks and historical experience. In circumstances where we are aware of a specific customer's inability to meet its financial obligations to us, we record a specific allowance for bad debts against amounts due to reduce the carrying amount of accounts receivable to the amount we reasonably believe will be collected. Inventory Inventory is stated at the lower of cost or net realizable value, with cost determined on a first-in, first-out basis. We regularly review inventory quantities based on actual loss experiences, projected future demand and remaining shelf life to record a provision for excess and obsolete inventory when appropriate. Leases Operating leases are included in operating lease right-of-use (“ROU”) asset, accrued expenses, and operating lease liability – non-current portion in our balance sheets. ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. We used the incremental borrowing rate based on information readily available at the time of recognition to determine the present value of the lease payments. The determination of our incremental borrowing rate requires management judgment based on information available at lease commencement. Revenue recognition We sell our products primarily through a direct sales force and to a lesser extent through a combination of sales agents and independent distributors. Our revenue consists primarily of the sale of our Barostim, which consists of two implantable components: a pulse generator and a stimulation lead. Under Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts with Customers (“ASC 606”), revenue is recognized when a customer obtains control of promised goods or services, in an amount that reflects the consideration that the entity expects to receive in exchange for those goods or services. To determine revenue recognition for arrangements that an entity determines are within the scope of ASC 606, we perform the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a performance obligation. We only apply the five-step model to contracts when it is probable that we will collect the consideration we are entitled to in exchange for the goods or services it transfers to the customer. We recognize net revenue on product sales, adjusted for any applicable estimates of variable consideration, when the customer obtains control of our product, which generally occurs at a point in time upon delivery based on the contractual shipping terms of a contract. Our contracts have a single performance obligation, and our payment terms with customers are generally between 30 and 90 days. Variable consideration related to certain customer rebates is estimated based on the amounts expected to be paid under the agreement with the customer. Stock-Based Compensation We recognize equity-based compensation expense for awards of equity instruments to employees and non-employees based on the grant date fair value of those awards in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Topic 718, Compensation—Stock Compensation (“ASC 718”). ASC 718 requires all equity-based compensation awards to employees and non-employee directors, including grants of restricted shares and stock options, to be recognized as expense in the statements of operations and comprehensive loss based on their grant date fair values. We estimate the grant date fair value of stock options using the Black-Scholes option pricing model, and the fair value of restricted stock units (“RSUs”) and performance stock units (“PSUs”) are equal to the closing price of our common stock on the grant date. We account for forfeitures as they occur. We expense the fair value of our equity-based compensation awards granted to employees on a straight-line basis over the associated service period, which is generally the period in which the related services are received for stock options and RSUs, and the performance period and any additional service period based on the probability of achieving the performance objectives for PSUs. Recent accounting pronouncements In November 2024, the FASB issued ASU 2024-03, Income Statement — Reporting Comprehensive Income (Subtopic 220-40): Disaggregation of Income Statement Expenses. The amendments require public business entities to provide enhanced disclosures related to the disaggregation of income statement expenses, including additional quantitative and qualitative information about the nature of expenses presented within relevant expense captions. The guidance is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027, with early adoption permitted. We have not yet adopted ASU 2024-03 and are in the process of evaluating the impact of the guidance on our consolidated financial statements. While the amendments will require additional disclosures and may require changes to internal data aggregation and reporting processes, we do not expect adoption to have a material impact on its results of operations, financial position, or cash flows.

Debt Disclosure [Abstract]

Debt

Innovatus Loan Agreement

On October 31, 2022, we entered into a Loan and Security Agreement (the “Loan Agreement”) with Innovatus Life Sciences Fund I, LP, as the collateral agent and a lender, allowing us to borrow, subject to our achievement of certain milestones, up to a total of $50.0 million in a series of term loans (collectively, the “Term Loans”). On January 9, 2026, we entered into an Amendment to our existing Loan Agreement. Pursuant to the Amendment, the term loans available were increased by $50.0 million, to an aggregate principal amount of up to $100.0 million, subject to our achievement of certain milestones, and the maturity date was extended to 2031. In connection with the Amendment, we borrowed an additional $10.0 million under the Loan Agreement. We had $60.0 million in outstanding Term Loans under the Loan Agreement as of June 30, 2026. The Term Loans require interest only payments through December 2029, followed by monthly principal and interest payments. A final payment of $2.7 million, equal to 4.5% of the original borrowed principal amount, is due in May 2031. The Term Loans bear interest at a floating rate per annum equal to the sum of (a) the greater of (i) the prime rate and (ii) 6.75%; plus (b) 2.65%, which margin will decrease to 2% after we achieve a positive adjusted EBITDA for two consecutive quarters. The Term Loans are secured by substantially all of our personal property. A performance covenant took effect upon the third tranche funding, requiring that we achieve 50% of the trailing twelve months revenue target set in the Board-approved revenue plan in effect for such period. The Loan Agreement requires the payment of certain penalties if the Term Loans are paid off prior to maturity for any reason, including pursuant to an acceleration clause, and includes various restrictive covenants, including a restriction on the payment of dividends or making other distributions or payments on our capital stock, subject to limited exceptions. We were in compliance with these covenants as of June 30, 2026.

In connection with the Loan Agreement, we recorded $2.2 million of debt issuance costs and discounts as a reduction of long-term debt.

The annual principal maturities of debt under the Loan Agreement are as follows:


(in thousands)	June 30, 2026
2026	$	—
2027	—
2028	—
2029	—
2030	41,250
Thereafter	18,750

Commitments and Contingencies Disclosure [Abstract]
Commitments and contingencies	Commitments and contingencies From time to time, we may have certain contingent liabilities that arise in the ordinary course of business. We accrue a liability for such matters when it is probable that future expenditures will be made, and such expenditures can be reasonably estimated. There have been no contingent liabilities requiring accrual or disclosure as of June 30, 2026 or December 31, 2025. On May 14, 2026, we received a civil investigative demand (“CID”) from the U.S. Department of Justice in connection with an investigation under the False Claims Act. The CID requested information and documents regarding an investigation into whether we caused the submission of false claims to government health insurance programs by improperly marketing our device, offering or paying kickbacks to healthcare providers or providing false information to government health insurance programs. We are cooperating with the investigation and are in the process of responding to the CID. We cannot predict the eventual scope, duration or outcome of this matter at this time and are unable to estimate the possibility of, or amount or range of, any possible financial loss related to this matter.

Retirement Benefits [Abstract]
Employee benefit plans	Employee benefit plans We sponsor a voluntary defined-contribution employee retirement plan (the “401(k) plan”) for our U.S. employees. The 401(k) plan provides that each participant may contribute pre-tax or post-tax compensation up to the statutory limit allowable. Under the 401(k) plan, each participant is fully vested in his or her deferred salary contributions when contributed. Beginning January 1, 2024, we adopted a policy to match a portion of employee contributions for all qualified employees participating in the 401(k) plan. We recorded an expense for matching contributions of $0.4 million for the three months ended June 30, 2026 and $0.3 million for the three months ended 2025. We recorded an expense for matching contributions of $0.8 million and $0.6 million for the six months ended June 30, 2026 and 2025.
