2. Summary of Significant Accounting Policies

Basis of Presentation and Consolidation

The accompanying condensed consolidated balance sheet as of June 30, 2023, the condensed consolidated statements of operations, the condensed consolidated statements of comprehensive income (loss), and the condensed consolidated statements of stockholders’ equity for the three and six months ended June 30, 2023 and 2022, and the condensed consolidated statements of cash flows for the six months ended June 30, 2023 and 2022 are unaudited. The unaudited condensed consolidated financial statements included herein have been prepared by the Company in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and the applicable rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”) for interim financial information. Accordingly, they do not include all of the information and notes required by U.S. GAAP for complete financial statements. The condensed consolidated balance sheet data as of December 31, 2022 was derived from the audited financial statements as of that date.

The unaudited condensed consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements and, in the opinion of management, reflect all adjustments of a normal recurring nature considered necessary to state fairly the Company’s financial position as of June 30, 2023, the results of its operations for the three and six months ended June 30, 2023 and 2022, the changes in its comprehensive income (loss) and stockholders’ equity for the three and six months ended June 30, 2023 and 2022, and its cash flows for the six months ended June 30, 2023 and 2022. The results for the three and six months ended June 30, 2023 are not necessarily indicative of the results that may be expected for the year ending December 31, 2023 or for any other future annual or interim period.

The information included in this Quarterly Report on Form 10-Q should be read in conjunction with the audited consolidated financial statements and notes thereto for the fiscal year ended December 31, 2022, included in the Company’s Annual Report on Form 10-K. There have been no changes to the Company’s significant accounting policies during the six months ended June 30, 2023, as compared to the significant accounting policies described in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022, except for the granting of restricted stock units with performance conditions to senior management during the three months ended March 31, 2023. Refer to Note “9. Stockholders’ Equity” for information on the Company’s accounting policy.

The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities and equity accounts; disclosure of contingent assets and liabilities at the date of the financial statements; and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, the Company evaluates its estimates, including those related to marketable investments, allowances for credit losses, the amount of variable consideration included in the transaction price, warranty reserve, valuation of inventories, useful lives of property and equipment, intangibles, operating and financing lease right-of-use (“ROU”) assets and liabilities, income taxes, contingent consideration and other contingencies, including the probability of achieving performance targets associated with equity awards with performance conditions, among others. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which

Penumbra, Inc.

Notes to Condensed Consolidated Financial Statements

(unaudited)

form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other data. Actual results could differ from those estimates.

Segments

The Company determined its operating segment on the same basis that it uses to evaluate its performance internally. The Company has one business activity: the design, development, manufacturing and marketing of innovative medical products, and operates as one operating segment. The Company’s chief operating decision-maker, its Chief Executive Officer, reviews its consolidated operating results for the purpose of allocating resources and evaluating financial performance.

3. Investments and Fair Value of Financial Instruments

Marketable Investments

The Company’s marketable investments have been classified and accounted for as available-for-sale. The following table presents the Company’s marketable investments as of June 30, 2023 and December 31, 2022 (in thousands):

	June 30, 2023
			Securities with net gains or losses in accumulated other comprehensive income (loss)
	Amortized Cost		Gross Unrealized Gains		Gross Unrealized Losses		Allowance  for  Credit Loss		Fair Value

U.S. treasury	18,021		$	1	$	(370)	$	—	$	17,652
U.S. agency and government sponsored securities	2,998		—		(65)		—		2,933
U.S. states and municipalities	12,615		—		(249)		—		12,366

Total	$	108,907	$	1	$	(2,012)	$	—	$	106,896

	December 31, 2022
			Securities with net gains or losses in accumulated other comprehensive income (loss)
	Amortized Cost		Gross Unrealized Gains		Gross Unrealized Losses		Allowance  for  Credit Loss		Fair Value
U.S. treasury	$	14,482	$	—	$	(478)	$	—	$	14,004
U.S. agency and government sponsored securities	6,999		—		(176)		—		6,823
U.S. states and municipalities	23,460		—		(501)		—		22,959
Corporate bonds	76,731		—		(2,345)		—		74,386
Total	$	121,672	$	—	$	(3,500)	$	—	$	118,172

As of June 30, 2023, the total amortized cost basis of the Company’s available-for-sale securities in an unrealized loss position exceeded its fair value by $2.0 million, which was primarily attributable to widening credit spreads and rising interest rates since purchase. The Company reviewed its available-for-sale securities in an unrealized loss position and concluded that the decline in fair value was not related to credit losses and is recoverable. During the three and six months ended June 30, 2023, no allowance for credit losses was recorded and instead the unrealized losses are reported as a component of accumulated other comprehensive loss.

Fair Value of Financial Instruments

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the measurement date. The accounting guidance establishes a three-tiered hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value:

Level 1 - Quoted prices in active markets for identical assets or liabilities.

Level 2 - Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

The categorization of a financial instrument within the valuation hierarchy is based on the lowest level of input that is significant to the fair value measurement.

The Company classifies its cash equivalents and marketable investments within Level 1 and Level 2, as it uses quoted market prices or alternative pricing sources and models utilizing market observable inputs.

The Company determined the fair value of its Level 1 financial instruments, which are traded in active markets, using quoted market prices for identical instruments.

Marketable investments classified within Level 2 of the fair value hierarchy are valued based on other observable inputs, including broker or dealer quotations or alternative pricing sources. When quoted prices in active markets for identical assets or liabilities are not available, the Company relies on non-binding quotes from its investment managers, which are based on proprietary valuation models of independent pricing services. These models generally use inputs such as observable market data, quoted market prices for similar instruments, historical pricing trends of a security as relative to its peers. To validate the fair value determination provided by its investment managers, the Company reviews the pricing movement in the context of overall market trends and trading information from its investment managers. In addition, the Company assesses the inputs and methods used in determining the fair value in order to determine the classification of securities in the fair value hierarchy.

The Company did not hold any Level 3 marketable investments as of June 30, 2023 or December 31, 2022. During the six months ended June 30, 2023 and 2022, the Company did not have any transfers between Level 1, Level 2 or Level 3 of the fair value hierarchy. Additionally, the Company did not have any financial assets and liabilities measured at fair value on a non-recurring basis as of June 30, 2023 or December 31, 2022.

The following tables set forth the Company’s financial assets measured at fair value by level within the fair value hierarchy as of June 30, 2023 and December 31, 2022 (in thousands):

7. Indebtedness

Credit Agreement

On April 24, 2020, the Company entered into a Credit Agreement (the “Credit Agreement”) with JPMorgan Chase Bank, N.A., as administrative agent and lender, and Bank of America, N.A. and Citibank, N.A. as lenders. The Credit Agreement is secured and provides for up to $100 million in available revolving borrowing capacity with an option, subject to certain conditions, for the Company to increase the aggregate borrowing capacity to up to $150 million, and originally matured on April 23, 2021. During the three months ended March 31, 2021 and 2022, the Credit Agreement was amended to extend the maturity date and make other changes to the terms of the Credit Agreement.

In the first quarter of 2023, the Company and JPMorgan Chase Bank, N.A., as administrative agent and lender, and Bank of America, N.A. and Citibank, N.A., as lenders, entered into Amendment No. 3 to the Credit Agreement. Pursuant to the amendment, (i) the maturity date of the Credit Agreement was extended from February 17, 2023 to February 16, 2024, (ii) certain changes were made to the reference benchmark interest rates, applicable margins and borrowing mechanics under the Credit Agreement, which have the overall effect of increasing the interest rates payable by the Company on amounts borrowed under the Credit Agreement, and (iii) the commitment fee payable on the average daily unused amount under the Credit Agreement was increased to 0.35% per annum.

The Credit Agreement requires the Company to maintain a minimum fixed charge coverage ratio and to not exceed a

12

Penumbra, Inc.

Notes to Condensed Consolidated Financial Statements

(unaudited)

maximum leverage ratio. As of June 30, 2023, the Company was in compliance with these requirements.

As of June 30, 2023 and December 31, 2022, there were no borrowings outstanding under the Credit Agreement.

8. Commitments and Contingencies

Royalty Obligations

In March 2005, the Company entered into a license agreement that requires the Company to make minimum royalty payments to the licensor on a quarterly basis. In July 2019, the Company amended the license agreement to extend its term for an additional ten years and to increase the required minimum annual royalty payments by $0.2 million. As of both June 30, 2023 and December 31, 2022, the amended license agreement required minimum quarterly royalty payments of $0.3 million. Unless terminated earlier, the term of the amended license agreement shall expire June 30, 2029.

In April 2012, the Company entered into an agreement that requires the Company to pay, on a quarterly basis, a 5% royalty on sales of products covered under applicable patents. The first commercial sale of covered products occurred in April 2014. Unless terminated earlier, the royalty term for each applicable product shall continue for fifteen years following the first commercial sale of such patented product, or when the applicable patent covering such product has expired, whichever is sooner.

Royalty expense included in cost of revenue for the three months ended June 30, 2023 and 2022 was $0.7 million and $0.6 million, respectively, and for the six months ended June 30, 2023 and 2022, was $1.3 million and $1.2 million, respectively.

Contingencies

From time to time, the Company may have certain contingent liabilities that arise in the ordinary course of business. 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.

Indemnification

The Company enters into standard indemnification arrangements in the ordinary course of business. In many such arrangements, the Company agrees to indemnify, hold harmless, and reimburse the indemnified parties for losses suffered or incurred by the indemnified parties 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 Company also agrees to indemnify many indemnified parties for product defect and similar claims. 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 Company has not incurred costs to defend lawsuits or settle claims related to these indemnification agreements. No liability associated with any of these indemnification requirements has been recorded to date.

Litigation

From time to time, the Company is subject to other claims and assessments in the ordinary course of business. The Company is not currently a party to any such litigation matter that, individually or in the aggregate, is expected to have a material adverse effect on the Company’s business, financial condition, results of operations or cash flows.

9. Stockholders’ Equity

Stock-based Compensation

Stock-based compensation expense is associated with restricted stock units (“RSUs”), RSUs with performance conditions (“PSUs”), stock options, and the Company’s Employee Stock Purchase Plan.

Certain RSUs granted to senior management during the three months ended March 31, 2023, will vest subject to the achievement of pre-established financial performance targets for the year ending December 31, 2023, and continued service. The fair value of these PSUs is based on the closing price of the Company's common stock on the date of grant. Stock-based compensation costs associated with these PSUs are recognized over the requisite service period of 4.25 years using graded

vesting which results in more accelerated expense recognition compared to traditional time-based vesting over the same vesting period. Each reporting period, the Company monitors the probability of achieving the performance targets and may adjust periodic stock-based compensation expense based on its determination of the likelihood of achieving these performance targets and the estimated number of shares of common stock that will vest. The actual number of PSUs awarded is based on the actual performance during the performance period compared to the performance targets.

The following table sets forth the stock-based compensation expense included in the Company’s condensed consolidated statements of operations for the three and six months ended June 30, 2023 and 2022 (in thousands):

	Three Months Ended June 30,				Six Months Ended June 30,
	2023		2022		2023		2022
Cost of revenue	$	1,281	$	880	$	2,472	$	1,736
Research and development	2,431		1,514		4,709		2,900
Sales, general and administrative	9,111		6,392		18,408		13,043
Total	$	12,823	$	8,786	$	25,589	$	17,679

As of June 30, 2023, total unrecognized compensation cost related to unvested share-based compensation arrangements, excluding PSUs, was $71.4 million, which is expected to be recognized over a weighted average period of 2.8 years.

As of June 30, 2023, total unrecognized compensation cost related to unvested PSU share-based compensation arrangements was $15.8 million, which is expected to be recognized over a weighted average period of 3.7 years.

The total stock-based compensation cost capitalized in inventory was $2.1 million and $2.2 million as of June 30, 2023 and December 31, 2022, respectively.

10. Accumulated Other Comprehensive Income (Loss)

Other comprehensive income (loss) consists of two components: unrealized gains or losses on the Company’s available-for-sale marketable investments and gains or losses from foreign currency translation adjustments. Until realized and reported as a component of consolidated net income (loss), these comprehensive income (loss) items accumulate and are included within accumulated other comprehensive income (loss). Unrealized gains and losses on the Company’s marketable investments are reclassified from accumulated other comprehensive income (loss) into earnings when realized upon sale, and are determined based on specific identification of securities sold. Gains and losses from the translation of assets and liabilities denominated in non-U.S. dollar functional currencies are included in accumulated other comprehensive income (loss).

The following table summarizes the changes in the accumulated balances during the period and includes information regarding the manner in which the reclassifications out of accumulated other comprehensive income (loss) into earnings affect the Company’s condensed consolidated statements of operations and condensed consolidated statements of comprehensive income (loss) (in thousands):

11. Income Taxes

The Company’s income tax expense (benefit), deferred tax assets and liabilities, and reserves for unrecognized tax benefits reflect management’s best assessment of estimated current and future taxes to be paid. The Company is subject to income taxes in both the United States and foreign jurisdictions. Significant judgment and estimates are required in determining the consolidated income tax expense (benefit).

During interim periods, the Company generally utilizes the estimated annual effective tax rate (“AETR”) method which involves the use of forecasted information. Under the AETR method, the provision is calculated by applying the estimated AETR for the full fiscal year to “ordinary” income or loss (pretax income or loss excluding unusual or infrequently occurring discrete items) for the reporting period. Jurisdictions with tax assets for which the Company believes a tax benefit cannot be realized are excluded from the computation of its AETR.

The Company’s provision for income taxes for the three months ended June 30, 2023 was $0.6 million, which was primarily due to tax expenses attributable to its worldwide profits offset by excess tax benefits from stock-based compensation attributable to its U.S. jurisdiction. The Company’s provision for income taxes for the three months ended June 30, 2022 was $2.5 million, which was primarily due to tax deficiencies (shortfalls) expenses from stock-based compensation attributable to its U.S. jurisdiction as a result of stock price fluctuation, offset by tax benefits attributable to its worldwide losses. The Company’s effective tax rate changed to 2.9% for the three months ended June 30, 2023 from (215.9)% for the three months ended June 30, 2022, primarily due to small tax expenses over relatively large worldwide profits in 2023 comparing to large tax expenses over relatively small worldwide losses in 2022.

The Company’s provision for income taxes for the six months ended June 30, 2023 was $0.7 million, which was primarily due to tax expenses attributable to its worldwide profits offset by excess tax benefits from stock-based compensation attributable to its U.S. jurisdiction. The Company’s benefit from income taxes for the six months ended June 30, 2022 was $2.7 million, which was primarily due to tax benefits attributable to its worldwide losses, offset by tax deficiencies (shortfall) expenses from stock-based compensation attributable to its U.S. jurisdiction as a result of stock price fluctuation. The Company’s effective tax rate changed to 2.4% for the six months ended June 30, 2023 from 42.5% for the six months ended June 30, 2022, primarily due to small tax expenses over relatively large worldwide profits in 2023 comparing to large tax benefits over relatively small worldwide losses in 2022.

Significant domestic deferred tax assets (“DTAs”) were generated in recent years, primarily due to excess tax benefits from stock option exercises and vesting of restricted stock units. The Company evaluates all available positive and negative evidence, objective and subjective in nature, in each reporting period to determine if sufficient taxable income will be generated to realize the benefits of its DTAs and, if not, a valuation allowance to reduce the DTAs is recorded.

As of June 30, 2023 and 2022, the Company maintains a valuation allowance against its Federal Research and Development Tax Credit DTAs as the Company could not conclude at the required more-likely-than-not level of certainty, that the benefit of these tax attributes would be realized prior to expiration. The Company intends to continue maintaining this full valuation allowance until there is sufficient evidence to reverse it. However, considering current earnings and anticipated future earnings, as well as the impact of IRC Section 174 requiring qualified research expenditures to be capitalized and amortized over 5 or 15 years, the Company anticipates net operating loss (“NOL”) utilization may be accelerated. As a consequence, the Company believes there is a reasonable possibility that sufficient positive evidence may become available to conclude this valuation allowance may no longer be needed within the next 12 months. Release of the valuation allowance will result in the recognition of Federal Research and Development Tax Credit DTAs and a decrease to income tax expenses for the period in which the release is recorded. The exact timing and amount of the valuation allowance release are highly dependent on the level

15

Penumbra, Inc.

Notes to Condensed Consolidated Financial Statements

(unaudited)

of taxable income in future years. The Company will continue to closely monitor the need for this valuation allowance in each subsequent reporting period.

As of June 30, 2023 and 2022, the company maintains a full valuation allowance against its California DTAs as the Company does not expect to generate sufficient future taxable income in California to realize the tax benefit due to the computation of California taxes under the single sales factor and non-conformity of the Section 174 capitalization rule.

The Company maintains that all foreign earnings, with the exception of a portion of the earnings of its German subsidiary, are permanently reinvested outside the United States and therefore deferred taxes attributable to such earnings are not provided for in the Company’s condensed consolidated financial statements as of June 30, 2023.

12. Net Income (Loss) per Share

The Company computed basic net income (loss) per share based on the weighted average number of shares of common stock outstanding during the period. The Company computed diluted net income (loss) per share based on the weighted average number of shares of common stock outstanding plus potentially dilutive common stock equivalents outstanding during the period using the treasury stock method. For the purposes of this calculation, stock options, restricted stock units and stock sold through the Company’s employee stock purchase plan are considered common stock equivalents.

A reconciliation of the numerator and denominator used in the calculation of the basic and diluted net income (loss) per share is as follows (in thousands, except share and per share amounts):

	Three Months Ended June 30,				Six Months Ended June 30,
	2023		2022		2023		2022
Numerator:
Net income (loss)	$	18,960	$	(3,687)	$	27,522	$	(3,608)
Denominator:
Weighted average shares used to compute net income (loss) attributable to common stockholders:
Basic	38,320,999		37,767,519		38,254,042		37,707,156
Potential dilutive stock-based options and awards	880,156		—		897,370		—
Diluted	39,201,155		37,767,519		39,151,412		37,707,156
Net income (loss) per share:
Basic	$	0.49	$	(0.10)	$	0.72	$	(0.10)
Diluted	$	0.48	$	(0.10)	$	0.70	$	(0.10)

For the three months ended June 30, 2023 and 2022, outstanding stock-based awards of 8 thousand and 1,766 thousand shares, respectively, and for the six months ended June 30, 2023 and 2022 outstanding stock-based awards of 8 thousand and 1,878 thousand shares, respectively, were excluded from the computation of diluted net income (loss) per share because their effect would have been anti-dilutive.

13. Revenues

Revenue Recognition

Revenue is recognized in an amount that reflects the consideration the Company expects to be entitled to in exchange for goods or services. All revenue recognized in the condensed consolidated statements of operations is considered to be revenue from contracts with customers.

China Distribution and Technology Licensing Agreement

In December 2020, the Company entered into a distribution and technology licensing arrangement with its existing distribution partner in China. In addition to modifying the Company’s standard distribution agreement with its partner in China, the Company agreed to license the technology for certain products to its partner in China to permit the manufacturing and commercialization of such products in China as well as provide certain regulatory support. During the three months ended March 31, 2022, the Company further amended the distribution agreement and entered into an additional license agreement, pursuant to which the Company agreed to license the technology for additional products to its partner in China on substantially the same terms as the existing license agreement. Apart from the standard distribution agreement, the Company will receive fixed payments upon transferring its distinct licensed technology and providing related regulatory support and royalty payments on the down-stream sale of the licensed products.

Performance Obligations

Delivery of products - The Company’s contracts with customers typically contain a single performance obligation, delivery of the Company’s products. Satisfaction of that performance obligation occurs when control of the promised goods transfers to the customer, which is generally upon shipment for non-consignment sale agreements and upon utilization for consignment sale agreements.

Payment terms - The Company’s payment terms vary by the type and location of our customer. The timing between fulfillment of performance obligations and when payment is due is not significant and does not give rise to financing transactions. The Company did not have any contracts with significant financing components as of June 30, 2023.

Product returns - The Company may allow customers to return products purchased at the Company’s discretion. The Company estimates the amount of its product sales that may be returned by its customers and records this estimate as a reduction of revenue in the period in which the related product revenue is recognized. The Company currently estimates product return liabilities using its own historic sales information, trends, industry data, and other relevant data points.

Warranties - The Company offers its standard warranty to all customers and it is not available for sale on a standalone basis. The Company’s standard warranty represents its guarantee that its products function as intended, are free from defects, and comply with agreed-upon specifications and quality standards. This assurance does not constitute a service and is not a separate performance obligation.

Transaction Price

Revenue is recorded at the net sales price, which includes estimates of variable consideration such as product returns utilizing historical return rates, rebates, discounts, and other adjustments to net revenue. To the extent the transaction price includes variable consideration, the Company estimates the amount of variable consideration that should be included in the transaction price. When determining if variable consideration should be constrained, management considers whether there are

17

factors that could result in a significant reversal of revenue and the likelihood of a potential reversal. Variable consideration is included in revenue only to the extent that it is probable that a significant reversal of the revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. These estimates are reassessed each reporting period. During the three and six months ended June 30, 2023, the Company made no material changes in estimates for variable consideration. When the Company performs shipping and handling activities after control of goods is transferred to the customer, they are considered as fulfillment activities, and costs are accrued for when the related revenue is recognized. Taxes collected from customers relating to product sales and remitted to governmental authorities are excluded from revenues.

Contract liabilities, net

The following information summarizes the Company’s contract assets and liabilities, net as of June 30, 2023 and December 31, 2022 (in thousands):

	June 30, 2023		December 31, 2022
Contract liabilities, net	$	7,883	$	8,783

Contract liabilities represents amounts that the Company has already invoiced and are ultimately expected to be recognized as revenue, but for which not all revenue recognition criteria have been met and is recognized as the associated performance obligations are satisfied. Contract assets for the periods presented primarily represent the difference between the revenue that was recognized based on the relative standalone selling price of the related performance obligations satisfied and the contractual billing terms in the arrangements. Revenue recognized during the three and six months ended June 30, 2023 relating to contract liabilities as of March 31, 2023 and December 31, 2022 was $0.4 million and $0.9 million, respectively.

Overview

Penumbra is a global healthcare company focused on innovative therapies. We design, develop, manufacture and market novel products and have a broad portfolio that addresses challenging medical conditions in markets with significant unmet need. Our team focuses on developing, manufacturing and marketing novel products for use by specialist physicians and healthcare providers to drive improved clinical outcomes and health. We believe that the cost-effectiveness of our products is attractive to our customers.

Since our founding in 2004, we have invested heavily in our product development capabilities in our major markets: neuro, vascular, and immersive healthcare. We have successfully developed, obtained regulatory clearance or approval for, and introduced products into the neurovascular market since 2007, vascular market since 2013, neurosurgical market since 2014, and immersive healthcare market since 2020, respectively. We continue to expand our portfolio of product offerings, while developing and iterating on our currently available products.

We expect to continue to develop and build our portfolio of products, including our thrombectomy, embolization and access and immersive technologies. Generally, when we introduce a next generation product or a new product designed to replace a current product, sales of the earlier generation product or the product replaced decline. Our research and development activities are centered around the development of new products and clinical activities designed to support our regulatory submissions and demonstrate the effectiveness of our products.

To address the challenging and significant clinical needs of our key markets, we have developed products that fall into the following broad product families:

Our neuro products fall into four broad product families:

•Neuro thrombectomy - Penumbra System, including Penumbra RED, JET, ACE catheters and the 3D Revascularization Device, Penumbra ENGINE and other components and accessories

•Neuro embolization - Penumbra SMART COIL, Penumbra Coil 400, POD400 and PAC400

•Neuro access - delivery catheters, consisting of Neuron, Neuron MAX Select, BENCHMARK, BMX96, BMX81, DDC, PX SLIM and SENDit

•Neurosurgical - Artemis Neuro Evacuation Device

Our vascular products fall into two broad product families:

•Vascular thrombectomy - INDIGO System designed for continuous or modulated aspiration, computer-orchestrated mechanical thrombectomy, including aspiration catheters, microprocessor-controlled software algorithms that orchestrate the interaction of our pump and catheters, separators, aspiration pump and accessories

19

Table of Contents

•Peripheral embolization - RUBY Coil System, Ruby LP, LANTERN Delivery Microcatheter and the POD System (POD and POD Packing Coil)

Our immersive healthcare products fall into one broad product family:

•REAL Immersive System - portfolio of products that leverages immersive computer-based technologies to deliver engaging, immersive therapeutics to promote better health, motor function and cognition

We support healthcare providers, hospitals and clinics in more than 100 countries. In the six months ended June 30, 2023 and 2022, 28.7% and 30.7% of our revenue, respectively, was generated from customers located outside of the United States. Our sales outside of the United States are denominated principally in the euro and Japanese yen, with some sales being denominated in other currencies. As a result, we have foreign exchange exposure but do not currently engage in hedging.

We generated revenue of $502.9 million and $412.2 million for the six months ended June 30, 2023 and 2022, respectively, an increase of $90.7 million. We generated income from operations of $25.9 million and a loss from operations of $4.2 million for the six months ended June 30, 2023 and 2022, respectively.

Factors Affecting Our Performance

There are a number of factors that have impacted, and we believe will continue to impact, our results of operations and growth. These factors include: 

•The COVID-19 pandemic and measures taken in response thereto, which have negatively affected, and may continue to negatively affect, our revenues and results of operations. For example, as a result of the pandemic and the response thereto, global supply chains have been impacted, and we may experience significant and unpredictable fluctuations in the availability and cost of components and raw materials used in our products.

•The rate at which we grow our salesforce and the speed at which newly hired salespeople become fully effective can impact our revenue growth or our costs incurred in anticipation of such growth.

•Our industry is intensely competitive and, in particular, we compete with a number of large, well-capitalized companies. We must continue to successfully compete in light of our competitors’ existing and future products and their resources to successfully market to the specialist physicians and other healthcare providers who use our products.

•We must continue to successfully introduce new products that gain acceptance with specialist physicians and other healthcare providers and successfully transition from existing products to new products, ensuring adequate supply. In addition, as we introduce new products and expand our production capacity, we anticipate additional personnel will be hired and trained to build our inventory of components and finished goods in advance of sales, which may cause quarterly fluctuations in our operating results and financial condition.

•Publications of clinical results by us, our competitors and other third parties can have a significant influence on whether, and the degree to which, our products are used by specialist physicians and the procedures and treatments those physicians choose to administer for a given condition.

•The specialist physicians who use our interventional products may not perform procedures during certain times of the year, such as those periods when they are at major medical conferences or are away from their practices for other reasons, the timing of which occurs irregularly during the year and from year to year.

•Most of our sales outside of the United States are denominated in the local currency of the country in which we sell our products. As a result, our revenue from international sales can be significantly impacted by fluctuations in foreign currency exchange rates.

•The availability and levels of reimbursement within the relevant healthcare payment system for healthcare providers for procedures in which our products are used.

In addition, we have experienced and expect to continue to experience meaningful variability in our quarterly revenue, gross profit and gross margin percentage as a result of a number of factors, including, but not limited to: the number of available selling days, which can be impacted by holidays; the mix of products sold; the geographic mix of where products are sold; the demand for our products and the products of our competitors; the timing of or failure to obtain regulatory approvals or clearances for products; increased competition; the timing of customer orders; inventory write-offs due to obsolescence; costs, benefits and timing of new product introductions; costs, benefits and timing of the acquisition and integration of businesses and product lines we may acquire; the availability and cost of components and raw materials; and fluctuations in foreign currency

exchange rates. We may experience quarters in which we have significant revenue growth sequentially followed by quarters of moderate or no revenue growth. Additionally, we may experience quarters in which operating expenses, in particular research and development expenses, fluctuate depending on the stage and timing of product development.

COVID-19 Pandemic

In March 2020, the World Health Organization declared the outbreak of COVID-19 as a pandemic, which spread throughout the U.S. and the world. In response, governments issued orders restricting certain activities, and while our business falls within the category of healthcare operations, which are essential businesses that have generally been permitted to continue operating during the COVID-19 pandemic, we have experienced, and may continue to experience, disruptions to our operations as a result of the pandemic. For example, at times during the pandemic, hospital resources have been diverted to fight the pandemic, and many government agencies, in conjunction with healthcare systems, have recommended the deferral of elective and semi-elective medical procedures. In addition, the pandemic and the response thereto have impacted global supply chains and labor markets, resulting in cost inflation and raw material supply constraints, as well as an increase in employee turnover rates in certain jurisdictions, which has impacted, and may continue to impact, our business. In order to navigate the pandemic, we made certain changes to how we manufacture, inspect and ship our products to prioritize the health and safety of our employees and to operate under the protocols mandated by our local and state governments.

While the acute phase of the pandemic has subsided due to the development and widespread availability of vaccines for COVID-19,we are unable to reliably predict the full impact that COVID-19 will have on our business due to numerous uncertainties, including the severity and duration of the pandemic, the global resurgences of cases, particularly as new variants of the virus spread, additional actions that may be taken by governmental authorities in response to the pandemic, the impact of the pandemic on the business of our customers, distributors and suppliers, other businesses and worldwide economies in general, our ability to have access to our customers to provide training and case support, and other factors identified in Part I, Item 1A “Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2022. We will continue to evaluate the nature and extent of the impact of COVID-19 on our business, consolidated results of operations, and financial condition.

Components of Results of Operations

Revenue. We sell our interventional products directly to hospitals and other healthcare providers and through distributors for use in procedures performed by specialist physicians to treat patients in two key markets: neuro and vascular disease. We sell our products through purchase orders, and we do not have long term purchase commitments from our customers. Revenue from product sales is recognized either on the date of shipment or the date of receipt by the customer, but is deferred for certain transactions when control has not yet transferred. With respect to products that we consign to hospitals, which primarily consist of coils, we recognize revenue at the time hospitals utilize products in a procedure. Revenue also includes shipping and handling costs that we charge to customers.

Cost of Revenue. Cost of revenue consists primarily of the cost of raw materials and components, personnel costs, including stock-based compensation, inbound freight charges, receiving costs, inspection and testing costs, warehousing costs, royalty expense, shipping and handling costs, and other labor and overhead costs incurred in the manufacturing of products. In addition, we record write-downs or write-offs of inventory in the event that a portion of our inventory becomes excess or obsolete.

We manufacture substantially all of our products in our manufacturing facilities in Alameda and Roseville, California.

Operating Expenses

Research and Development (“R&D”). R&D expenses primarily consist of product development, clinical and regulatory expenses, materials, depreciation and other costs associated with the development of our products. R&D expenses also include salaries, benefits and other related costs, including stock-based compensation, for personnel and consultants. We generally expense R&D costs as they are incurred, with the exception of certain costs incurred for the development of computer software for internal use related to our REAL Immersive System offerings. We capitalize certain costs when it is determined that it is probable that the project will be completed and the software will be used to perform the function intended, and the preliminary project stage is completed. Capitalized internal use software development costs are included in property and equipment, net within the condensed consolidated balance sheets.

Sales, General and Administrative (“SG&A”). SG&A expenses primarily consist of salaries, benefits and other related costs, including stock-based compensation, for personnel and consultants engaged in sales, marketing, finance, legal, compliance, administrative, facilities, information technology and human resource activities. Our SG&A expenses also include

marketing trials, medical education, training, commissions, generally based on sales, to direct sales representatives, amortization of acquired intangible assets and acquisition-related costs.

Provision For (Benefit from) Income Taxes

We are taxed at the rates applicable within each jurisdiction in which we operate. The composite income tax rate, tax provisions, deferred tax assets (“DTAs”) and deferred tax liabilities will vary according to the jurisdiction in which profits arise. Tax laws are complex and subject to different interpretations by management and the respective governmental taxing authorities, and require us to exercise judgment in determining our income tax provision, our deferred tax assets and deferred tax liabilities and the potential valuation allowance recorded against our net DTAs. Deferred tax assets and liabilities are determined using the enacted tax rates in effect for the years in which those tax assets are expected to be realized. A valuation allowance is established when it is more likely than not that the future realization of all or some of the DTAs will not be achieved.

Three Months Ended June 30, 2023 Compared to the Three Months Ended June 30, 2022

Revenue

	Three Months Ended June 30,				Change
	2023		2022		$		%
	(in thousands, except for percentages)
Vascular	$	152,684	$	123,543	$	29,141	23.6	%
Neuro	108,815		84,801		24,014		28.3	%
Total	$	261,499	$	208,344	$	53,155	25.5	%

Revenue increased $53.2 million, or 25.5%, to $261.5 million in the three months ended June 30, 2023, from $208.3 million in the three months ended June 30, 2022. Overall revenue growth was primarily due to an increase in sales of new and existing products within our vascular and neuro businesses.

Revenue from our vascular products increased $29.1 million, or 23.6%, to $152.7 million in the three months ended June 30, 2023, from $123.5 million in the three months ended June 30, 2022. This increase was driven by a 49.8% increase in sales of our vascular thrombectomy products in the United States and primarily attributable to sales of new products and further market penetration of our existing products while the rest of our vascular business remained relatively flat. Prices for our vascular products remained substantially unchanged during the period.

Revenue from our neuro products increased $24.0 million, or 28.3%, to $108.8 million in the three months ended June 30, 2023, from $84.8 million in the three months ended June 30, 2022. This increase was primarily attributable to sales of new products and further market penetration of our existing products in Europe and the United States. The increase in product sales was driven by an increase in sales of our neuro thrombectomy products and neuro access products, which globally increased by 32.4% and 27.6%, respectively, in the three months ended June 30, 2023, partially offset by a decrease in sales of our neuro embolization products, which decreased by 16.1% in the three months ended June 30, 2023. Prices for our neuro products remained substantially unchanged during the period.

Revenue by Geographic Area

The following table presents revenue by geographic area, based on our customers’ shipping destinations, for the three months ended June 30, 2023 and 2022:

	Three Months Ended June 30,								Change

	(in thousands, except for percentages)
United States	$	186,772	71.4	%	$	141,456	67.9	%	$	45,316	32.0	%
International	74,727		28.6	%	66,888		32.1	%	7,839		11.7	%
Total	$	261,499	100.0	%	$	208,344	100.0	%	$	53,155	25.5	%

Revenue from product sales in international markets increased $7.8 million, or 11.7%, to $74.7 million in the three months ended June 30, 2023, from $66.9 million in the three months ended June 30, 2022. Revenue from international sales represented 28.6% and 32.1% of our total revenue for the three months ended June 30, 2023 and 2022, respectively.

Gross Margin

	Three Months Ended June 30,						Change
	2023			2022			$		%
	(in thousands, except for percentages)
Cost of revenue	$	94,638		$	74,309		$	20,329	27.4	%
Gross profit	$	166,861		$	134,035		$	32,826	24.5	%
Gross margin %	63.8		%	64.3		%

Gross margin remained relatively flat, decreasing by 0.5 percentage points to 63.8% in the three months ended June 30, 2023, from 64.3% in the three months ended June 30, 2022. Gross margin is impacted by product mix, regional mix, start-up costs associated with new product launches, and macroeconomic factors such as inflation headwinds. As such, with favorable product mix, improvement in productivity, and by leveraging our fixed costs on higher volume of new product sales during the year, our gross margin may be positively impacted in the future.

Research and Development (“R&D”)

	Three Months Ended June 30,						Change
	2023			2022			$		%
	(in thousands, except for percentages)
R&D	$	21,537		$	19,559		$	1,978	10.1	%
R&D as a percentage of revenue	8.2		%	9.4		%

R&D expenses increased by $2.0 million, or 10.1%, to $21.5 million in the three months ended June 30, 2023, from $19.6 million in the three months ended June 30, 2022. The increase was primarily due to a $1.7 million increase in personnel-related expenses.

We have continued to make investments, and plan to continue to make investments, in the development of our products. As part of our ongoing investment in the development of our products, we may incur additional expenses related to research and development milestones. In addition, we have experienced in the past, and may continue to experience in the future, variability in expenses incurred due to the timing and costs of clinical trials and product development, which may include additional personnel-related expenses in conjunction with the launch of new products.

SG&A expenses increased by $12.8 million, or 11.2%, to $127.4 million in the three months ended June 30, 2023, from $114.6 million in the three months ended June 30, 2022. The increase was primarily due to a $8.6 million increase in personnel-related expenses to support our growth.

As we continue to invest in our growth, we have expanded and may continue to expand our sales, marketing, and general and administrative teams through the hiring of additional employees in critical roles that support our strategic initiatives. In addition, we have experienced in the past, and may continue to experience in the future, variability in expenses incurred due to the timing and costs of investments to support the business.

Provision for income taxes

	Three Months Ended June 30,						Change
	2023			2022			$		%
	(in thousands, except for percentages)
Provision for income taxes	$	576		$	2,520		$	(1,944)	(77.1)	%
Effective tax rate	2.9		%	(215.9)		%

Our provision for income taxes was $0.6 million for the three months ended June 30, 2023, which was primarily due to tax expenses attributable to our worldwide profits offset by excess tax benefits from stock-based compensation attributable to our U.S. jurisdiction. Our provision for income taxes was $2.5 million for the three months ended June 30, 2022, which was primarily due to tax deficiencies (shortfalls) expenses from stock based compensation attributable to our U.S. jurisdiction as a result of stock price fluctuation, offset by tax benefits attributable to our worldwide losses.

Our effective tax rate changed to 2.9% for the three months ended June 30, 2023 from (215.9)% for the three months ended June 30, 2022, primarily due to small tax expenses over relatively large worldwide profits in 2023 comparing to large tax expenses over relatively small worldwide losses in 2022.

Prospectively, our effective tax rate will likely be driven by (1) permanent differences in taxable income for tax and financial reporting purposes, (2) tax expense or benefit attributable to our worldwide financial result, and (3) discrete tax adjustments such as excess tax benefits or deficiencies related to stock-based compensation. Our income tax provision is subject to volatility as the amount of excess tax benefits or deficiencies can fluctuate from period to period based on the price of our stock, the volume of share-based grants settled or vested, and the fair value assigned to equity awards under U.S. GAAP.

As of June 30, 2023 and 2022, we maintain a valuation allowance against our Federal Research and Development Tax Credit DTAs as we could not conclude at the required more-likely-than-not level of certainty, that the benefit of these tax attributes would be realized prior to expiration. We intend to continue maintaining this full valuation allowance until there is sufficient evidence to reverse it. However, considering current earnings and anticipated future earnings, as well as the impact of IRC Section 174 requiring qualified research expenditures to be capitalized and amortized over 5 or 15 years, we anticipate net operating loss (“NOL”) utilization may be accelerated. As a consequence, we believe there is a reasonable possibility that sufficient positive evidence may become available to conclude this valuation allowance may no longer be needed within the next 12 months. Release of the valuation allowance will result in the recognition of Federal Research and Development Tax Credit DTAs and a decrease to income tax expenses for the period in which the release is recorded. The exact timing and amount of the valuation allowance release are highly dependent on the level of taxable income in future years. We will continue to closely monitor the need for this valuation allowance in each subsequent reporting period.

Revenue increased $90.7 million, or 22.0%, to $502.9 million in the six months ended June 30, 2023, from $412.2 million in the six months ended June 30, 2022. Overall revenue growth was primarily due to an increase in sales of new and existing products within our vascular and neuro businesses.

Revenue from our vascular products increased $49.2 million, or 20.0%, to $295.5 million in the six months ended June 30, 2023, from $246.4 million in the six months ended June 30, 2022. This increase in revenue from our vascular products was primarily attributable to increased revenue in the United States and was driven by sales of our vascular thrombectomy products and peripheral embolization products, which globally increased by 23.5% and 14.1%, respectively, in the six months ended June 30, 2023. These increases were primarily due to higher sales volume as a result of sales of new products and further market penetration of our existing products. Prices for our vascular products remained substantially unchanged during the period.

Revenue from our neuro products increased $41.5 million, or 25.0%, to $207.4 million in the six months ended June 30, 2023, from $165.9 million in the six months ended June 30, 2022. This increase in revenue from our neuro products was primarily attributable to increased revenue in Europe and the United States, sales of new products, and further market penetration of our existing products. This increase was driven by an increase in sales of our neuro access products and neuro thrombectomy products, which globally increased by 31.3% and 25.7%, respectively, in the six months ended June 30, 2023, partially offset by a decrease in sales of our neuro embolization products of 14.9% in the six months ended June 30, 2023.

Revenue from international sales represented 28.7% and 30.7% of our total revenue for the six months ended June 30, 2023 and 2022, respectively.

Gross Margin

Cost of revenue	$	184,964		$	150,786		$	34,178	22.7	%
Gross profit	$	317,933		$	261,453		$	56,480	21.6	%
Gross margin %	63.2		%	63.4		%

Gross margin remained relatively flat, decreasing by 0.2 percentage point to 63.2% in the six months ended June 30, 2023, from 63.4% in the six months ended June 30, 2022. Gross margin is impacted by product mix, regional mix, start-up costs associated with new product launches, and macroeconomic factors such as inflation headwinds. As such, with favorable product mix, improvement in productivity, and by leveraging our fixed costs on higher volume of new product sales during the year, our gross margin may be positively impacted in the future.

Research and Development (“R&D”)

	Six Months Ended June 30,						Change
	2023			2022			$		%

R&D	$	41,523		$	40,123		$	1,400	3.5	%
R&D as a percentage of revenue	8.3		%	9.7		%

R&D expenses increased by $1.4 million, or 3.5%, to $41.5 million in the six months ended June 30, 2023, from $40.1 million in the six months ended June 30, 2022. The increase was primarily due to a $2.6 million increase in personnel-related expenses, partially offset by a $1.6 million decrease in product development and testing costs.

We have continued to make investments, and plan to continue to make investments, in the development of our products. As part of our ongoing investment in the development of our products, we may incur additional expenses related to research and development milestones. In addition, we have experienced in the past, and may continue to experience in the future, variability in expenses incurred due to the timing and costs of clinical trials and product development, which may include additional personnel-related expenses in conjunction with the launch of new products.

Sales, General and Administrative (SG&A)

SG&A	$	250,513		$	225,515		$	24,998	11.1	%
SG&A as a percentage of revenue	49.8		%	54.7		%

SG&A expenses increased by $25.0 million, or 11.1%, to $250.5 million in the six months ended June 30, 2023, from $225.5 million in the six months ended June 30, 2022. The increase was primarily due to a $19.7 million increase in personnel-related expense driven by an increase in headcount and related expenses to support our growth.

As we continue to invest in our growth, we have expanded and may continue to expand our sales, marketing, and general and administrative teams through the hiring of additional employees in critical roles that support our strategic initiatives. In addition, we have experienced in the past, and may continue to experience in the future, variability in expenses incurred due to the timing and costs of investments to support the business.

Provision for (benefit from) income taxes

	Six Months Ended June 30,						Change
	2023			2022			$		%
	(in thousands, except for percentages)
Provision for (benefit from) income taxes	$	666		$	(2,663)		$	3,329	(125.0)	%
Effective tax rate	2.4		%	42.5		%

Our provision for income taxes was $0.7 million for the six months ended June 30, 2023, which was primarily due to tax expenses attributable to our worldwide profits offset by tax benefits from stock-based compensation attributable to our U.S. jurisdiction. Our benefit from income taxes was $2.7 million for the six months ended June 30, 2022, which was primarily due to tax benefits attributable to our worldwide losses during the period, offset by excess tax deficiencies (shortfalls) expenses from stock-based compensation attributable to our U.S. jurisdiction as a result of stock price fluctuation.

The effective tax rate changed to 2.4% for the six months ended June 30, 2023 from 42.5% for the six months ended June 30, 2022, primarily due to small tax expenses over relatively large worldwide profits in 2023 comparing to large tax benefits over relatively small worldwide losses in 2023.

Prospectively, our effective tax rate will likely be driven by (1) permanent differences in taxable income for tax and financial reporting purposes, (2) tax expense or benefit attributable to our worldwide financial results, and (3) discrete tax adjustments such as excess tax benefits or deficiencies related to stock-based compensation. Our income tax provision can be volatile as the amount of excess tax benefits or deficiencies can fluctuate from period to period due to the price of our stock, the volume of share-based grants exercised or vested, and the fair value assigned to equity awards under U.S. GAAP. In addition, changes in tax law or our interpretation thereof, and changes to our valuation allowance could result in fluctuations in our effective tax rate.

26

Table of Contents

As of June 30, 2023 and 2022, we maintain a valuation allowance against our Federal Research and Development Tax Credit DTAs as we could not conclude at the required more-likely-than-not level of certainty, that the benefit of these tax attributes would be realized prior to expiration. We intend to continue maintaining this full valuation allowance until there is sufficient evidence to reverse it. However, considering current earnings and anticipated future earnings, as well as the impact of IRC Section 174 requiring qualified research expenditures to be capitalized and amortized over 5 or 15 years, we anticipate net operating loss (“NOL”) utilization may be accelerated. As a consequence, we believe there is a reasonable possibility that sufficient positive evidence may become available to conclude this valuation allowance may no longer be needed within the next 12 months. Release of the valuation allowance will result in the recognition of Federal Research and Development Tax Credit DTAs and a decrease to income tax expenses for the period in which the release is recorded. The exact timing and amount of the valuation allowance release are highly dependent on the level of taxable income in future years. We will continue to closely monitor the need for this valuation allowance in each subsequent reporting period.

Liquidity and Capital Resources

As of June 30, 2023, we had $683.8 million in working capital, which included $114.2 million in cash and cash equivalents and $106.9 million in marketable investments. As of June 30, 2023, we held approximately 15.5% of our cash and cash equivalents in foreign entities.

In addition to our existing cash and cash equivalents and marketable investment balances, our principal source of liquidity is our accounts receivable. In order to further strengthen our liquidity position and financial flexibility, on April 24, 2020 we entered into a Credit Agreement (the “Credit Agreement”) with JPMorgan Chase Bank, N.A., as administrative agent and lender, and Bank of America, N.A. and Citibank, N.A. as lenders. The Credit Agreement is secured and provides for up to $100 million in available revolving borrowing capacity with an option, subject to certain conditions, for us to increase the aggregate borrowing capacity to up to $150 million. The Credit Agreement originally matured on April 23, 2021 and was subsequently amended during the three months ended March 31, 2021, 2022 and 2023 to extend the maturity date and make other changes to the terms of the Credit Agreement. The Credit Agreement currently matures on February 16, 2024. See Note “7. Indebtedness” to our condensed consolidated financial statements in Part I, Item 1 of this Quarterly Report on Form 10-Q for more information.

We believe these sources of liquidity will be sufficient to meet our liquidity requirements for at least the next 12 months. Our principal liquidity requirements are to fund our operations, expand manufacturing operations which includes, but is not limited to, maintaining sufficient levels of inventory to meet the anticipated demand of our customers, fund research and development activities and fund our capital expenditures. We may also lease or purchase additional facilities to facilitate our growth. We expect to continue to make investments as we launch new products, expand our manufacturing operations and information technology infrastructures and further expand into international markets. We may, however, require or elect to secure additional financing as we continue to execute our business strategy. If we require or elect to raise additional funds, we may do so through equity or debt financing, which may not be available on favorable terms, could result in dilution to our stockholders, could result in changes to our capital structure, and could require us to agree to covenants that limit our operating flexibility.

The following table summarizes our cash and cash equivalents, marketable investments and selected working capital data as of June 30, 2023 and December 31, 2022:

	June 30, 2023		December 31, 2022

The following table sets forth, for the periods indicated, our beginning balance of cash and cash equivalents, net cash flows provided by (used in) operating, investing and financing activities and our ending balance of cash and cash equivalents:

Net cash provided by financing activities	10,070		6,490
Cash and cash equivalents and restricted cash at end of period	114,167		58,234

Net Cash Provided By (Used In) Operating Activities

Net cash provided by (used in) operating activities consists primarily of consolidated net income adjusted for certain non-cash items (including depreciation and amortization, stock-based compensation expense, inventory write-downs, and changes in deferred tax balances), and the effect of changes in working capital and other activities.

Net cash provided by operating activities was $30.2 million during the six months ended June 30, 2023 and consisted of consolidated net income of $27.5 million and non-cash items of $41.4 million, offset by net changes in operating assets and liabilities of $38.7 million. The change in operating assets and liabilities primarily relates to an increase in inventories of $25.8 million to support our growth, an increase in accounts receivable of $8.4 million due to timing of receipt of payment, and an increase in prepaid expenses and other current and non-current assets of $5.9 million. This was partially offset by an increase in accrued expenses and other non-current liabilities of $1.6 million.

Net cash used in operating activities was $44.1 million during the six months ended June 30, 2022 and consisted of consolidated net loss of $3.6 million and non-cash items of $27.4 million, offset by net changes in operating assets and liabilities of $67.9 million. The change in operating assets and liabilities includes an increase in accounts receivable of $54.3 million due to timing of receipt of payment, an increase in inventories of $36.1 million to support our growth, and an increase in prepaid expenses and other current and non-current assets of $2.5 million. This was partially offset by an increase in accrued expenses and other non-current liabilities of $15.7 million, an increase in accounts payable of $9.0 million, and proceeds of $0.2 million received related to lease incentives from operating leases.

Net Cash Provided By Investing Activities

Net cash provided by investing activities relates primarily to proceeds from maturities and sales of marketable investments, net of purchases, and capital expenditures.

Net cash provided by investing activities was $4.0 million during the six months ended June 30, 2023 and primarily consisted of $12.8 million in proceeds from maturities of marketable investments, net of purchases, which was partially offset by capital expenditures of $8.2 million.

Net cash provided by investing activities was $36.4 million during the six months ended June 30, 2022 and primarily consisted of proceeds from maturities and sales of marketable investments of $45.8 million, partially offset by capital expenditures of $9.4 million.

Net Cash Provided By Financing Activities

Net cash provided by financing activities primarily relates to payments of employee taxes related to vested restricted stock units, payments towards the reduction of our finance lease obligations, and proceeds from exercises of stock options and issuance of common stock under our employee stock purchase plan.

28

Table of Contents

Net cash provided by financing activities was $10.1 million during the six months ended June 30, 2023 and primarily consisted of proceeds from the issuance of common stock under our employee stock purchase plan of $8.4 million and proceeds from exercises of stock options of $3.8 million, partially offset by $1.0 million of payments of employee taxes related to vested restricted stock units and $1.0 million in payments towards finance leases.

Net cash provided by financing activities was $6.5 million during the six months ended June 30, 2022 and primarily consisted of proceeds from the issuance of common stock under our employee stock purchase plan of $8.0 million and proceeds from exercises of stock options of $4.6 million. This was partially offset by $5.1 million of payments of employee taxes related to vested restricted stock units and $0.9 million in payments towards finance leases.

Contractual Obligations and Commitments

There have been no other material changes to our contractual obligations and commitments as of June 30, 2023 from those disclosed in our Annual Report on Form 10-K for the year ended December 31, 2022.

Critical Accounting Policies and Estimates

We have prepared our financial statements in accordance with U.S. GAAP. Our preparation of these financial statements requires us to make estimates, assumptions, and judgments that affect the reported amounts of assets, liabilities, expenses, and related disclosures at the date of the financial statements, as well as revenue and expenses recorded during the reporting periods. We evaluate our estimates and judgments on an ongoing basis. We base our estimates on historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results could therefore differ materially from these estimates under different assumptions or conditions.

There have been no material changes to our critical accounting policies from those described in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in our Annual Report on Form 10-K for the year ended December 31, 2022.

Recently Issued Accounting Standards

No recently issued accounting standards are expected to impact the Company.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

We are exposed to various market risks, which may result in potential losses arising from adverse changes in market rates, such as interest rates and foreign exchange rates. We do not enter into derivatives or other financial instruments for trading or speculative purposes and do not believe we are exposed to material market risk with respect to our cash and cash equivalents or our marketable investments.

Interest Rate Risk. We had cash and cash equivalents of $114.2 million as of June 30, 2023, which consisted of funds held in money market funds, general checking and savings accounts. In addition, we had marketable investments of $106.9 million, which consisted primarily of corporate bonds, certificate of deposit, U.S. agency and government sponsored securities, and U.S. states and municipalities. Our investment policy is focused on the preservation of capital and supporting our liquidity needs. Under the policy, we invest in highly rated securities, while limiting the amount of credit exposure to any one issuer other than the U.S. government. We do not invest in financial instruments for trading or speculative purposes, nor do we use leveraged financial instruments. We utilize external investment managers who adhere to the guidelines of our investment policy. The revolving loans under the Credit Agreement bear interest at: (1) the adjusted EURIBOR rate, plus an applicable rate, for euro currency revolving borrowing; or (2) an alternate base rate, daily simple SOFR, or adjusted term SOFR rate, as applicable, plus an applicable rate, for revolving borrowing in U.S. dollars. As of June 30, 2023, there were no borrowings outstanding under the Credit Agreement. A hypothetical 100 basis point change in interest rates would not have a material impact on the value of our cash and cash equivalents or marketable investments.

Foreign Exchange Risk Management. We operate in countries other than the United States, and, therefore, we are exposed to foreign currency risks. We bill most sales outside of the United States in local currencies, primarily euro and Japanese yen, with some sales being denominated in other currencies. We expect that the percentage of our sales denominated in foreign currencies may increase in the foreseeable future as we continue to expand into international markets. When sales or expenses are not denominated in U.S. dollars, a fluctuation in exchange rates could affect our net income. We do not believe our net income would be materially impacted by an immediate 10% adverse change in foreign exchange rates. We do not currently hedge our exposure to foreign currency exchange rate fluctuations; however, we may choose to hedge our exposure in the future.

While our gross margin for the six months ended June 30, 2023 was primarily impacted by product mix, regional mix, start-up costs associated with new product launches, and macroeconomic factors such as inflation headwinds, changes in prices did not have a significant impact on our results of operations for any periods presented on our consolidated financial statements.

ITEM 4. CONTROLS AND PROCEDURES.

Evaluation of Disclosure Controls and Procedures

An evaluation as of June 30, 2023 was carried out under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, of the effectiveness of our “disclosure controls and procedures,” which are defined in Rule 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), as controls and other procedures of a company that are designed to ensure that the 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, and that such information is accumulated and communicated to the company’s management, including its principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure. Based upon that evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) were effective at June 30, 2023.

Changes in Internal Control Over Financial Reporting

There was no change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the quarterly period ended June 30, 2023 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Limitations on the Effectiveness of Controls

A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Because of inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues, if any, within a company have been detected. Accordingly, our disclosure controls and procedures are designed to provide reasonable, not absolute, assurance that the objectives of our disclosure control system are met and, as set forth above, our principal executive officer and principal financial officer have concluded, based on their evaluation as of the end of the period covered by this report, that our disclosure controls and procedures were effective to provide reasonable assurance that the objectives of our disclosure control system were met.

PART II - OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS.

For information with respect to Legal Proceedings, see Note “8. Commitments and Contingencies” to our condensed consolidated financial statements in Part I, Item 1 of this Quarterly Report on Form 10-Q.

On April 7, 2023, a former contractor who had been retained by the Company through a third party staffing agency filed a putative class action lawsuit as well as a Private Attorney General Act (“PAGA”) representative action complaint against the Company in the Superior Court of the State of California for the County of Alameda, on behalf of the contractor and similarly situated Company contractors and employees in California, alleging various claims pursuant to the California Labor Code related to wages, overtime, meal and rest breaks, reimbursement of business expenses, wage statements and records, and other similar allegations. Additionally, on April 10, 2023, a current employee of the Company filed a PAGA representative action complaint against the Company in the Superior Court of the State of California for the County of Alameda, on behalf of the employee and similarly situated Company employees in California, alleging similar claims. The complaints seek payment of various alleged unpaid wages, penalties, interest and attorneys’ fees in unspecified amounts. The Company believes the claims lack merit, and intends to defend itself vigorously. Given the early stage of these proceedings, it is not yet possible to reliably determine any potential liability that could result from these matters. Accordingly, the Company has not accrued any amount for potential losses associated with these matters.

ITEM 1A. RISK FACTORS.

There have been no material changes to our risk factors reported in, or new risk factors identified since the filing of, our Annual Report on Form 10-K for the year ended December 31, 2022, which was filed with the SEC on February 23, 2023.

Basis of Presentation and Consolidation

The accompanying condensed consolidated balance sheet as of June 30, 2023, the condensed consolidated statements of operations, the condensed consolidated statements of comprehensive income (loss), and the condensed consolidated statements of stockholders’ equity for the three and six months ended June 30, 2023 and 2022, and the condensed consolidated statements of cash flows for the six months ended June 30, 2023 and 2022 are unaudited. The unaudited condensed consolidated financial statements included herein have been prepared by the Company in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and the applicable rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”) for interim financial information. Accordingly, they do not include all of the information and notes required by U.S. GAAP for complete financial statements. The condensed consolidated balance sheet data as of December 31, 2022 was derived from the audited financial statements as of that date.

The unaudited condensed consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements and, in the opinion of management, reflect all adjustments of a normal recurring nature considered necessary to state fairly the Company’s financial position as of June 30, 2023, the results of its operations for the three and six months ended June 30, 2023 and 2022, the changes in its comprehensive income (loss) and stockholders’ equity for the three and six months ended June 30, 2023 and 2022, and its cash flows for the six months ended June 30, 2023 and 2022. The results for the three and six months ended June 30, 2023 are not necessarily indicative of the results that may be expected for the year ending December 31, 2023 or for any other future annual or interim period.

The information included in this Quarterly Report on Form 10-Q should be read in conjunction with the audited consolidated financial statements and notes thereto for the fiscal year ended December 31, 2022, included in the Company’s Annual Report on Form 10-K. There have been no changes to the Company’s significant accounting policies during the six months ended June 30, 2023, as compared to the significant accounting policies described in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022, except for the granting of restricted stock units with performance conditions to senior management during the three months ended March 31, 2023. Refer to Note “9. Stockholders’ Equity” for information on the Company’s accounting policy.

The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities and equity accounts; disclosure of contingent assets and liabilities at the date of the financial statements; and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, the Company evaluates its estimates, including those related to marketable investments, allowances for credit losses, the amount of variable consideration included in the transaction price, warranty reserve, valuation of inventories, useful lives of property and equipment, intangibles, operating and financing lease right-of-use (“ROU”) assets and liabilities, income taxes, contingent consideration and other contingencies, including the probability of achieving performance targets associated with equity awards with performance conditions, among others. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under 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 data. Actual results could differ from those estimates.

Segments

The Company determined its operating segment on the same basis that it uses to evaluate its performance internally. The Company has one business activity: the design, development, manufacturing and marketing of innovative medical products, and operates as one operating segment. The Company’s chief operating decision-maker, its Chief Executive Officer, reviews its consolidated operating results for the purpose of allocating resources and evaluating financial performance.

The Company’s marketable investments have been classified and accounted for as available-for-sale. The following table presents the Company’s marketable investments as of June 30, 2023 and December 31, 2022 (in thousands):

Total	$	121,672	$	—	$	(3,500)	$	—	$	118,172

As of June 30, 2023, the total amortized cost basis of the Company’s available-for-sale securities in an unrealized loss position exceeded its fair value by $2.0 million, which was primarily attributable to widening credit spreads and rising interest rates since purchase. The Company reviewed its available-for-sale securities in an unrealized loss position and concluded that the decline in fair value was not related to credit losses and is recoverable. During the three and six months ended June 30, 2023, no allowance for credit losses was recorded and instead the unrealized losses are reported as a component of accumulated other comprehensive loss.

The following tables present the gross unrealized losses and the fair value for those marketable investments that were in an unrealized loss position for less than twelve months or for twelve months or more as of June 30, 2023 and December 31, 2022 (in thousands):

Fair Value of Financial Instruments

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the measurement date. The accounting guidance establishes a three-tiered hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value:

Level 1 - Quoted prices in active markets for identical assets or liabilities.

Level 2 - Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

The categorization of a financial instrument within the valuation hierarchy is based on the lowest level of input that is significant to the fair value measurement.

The Company classifies its cash equivalents and marketable investments within Level 1 and Level 2, as it uses quoted market prices or alternative pricing sources and models utilizing market observable inputs.

The Company determined the fair value of its Level 1 financial instruments, which are traded in active markets, using quoted market prices for identical instruments.

Marketable investments classified within Level 2 of the fair value hierarchy are valued based on other observable inputs, including broker or dealer quotations or alternative pricing sources. When quoted prices in active markets for identical assets or liabilities are not available, the Company relies on non-binding quotes from its investment managers, which are based on proprietary valuation models of independent pricing services. These models generally use inputs such as observable market data, quoted market prices for similar instruments, historical pricing trends of a security as relative to its peers. To validate the fair value determination provided by its investment managers, the Company reviews the pricing movement in the context of overall market trends and trading information from its investment managers. In addition, the Company assesses the inputs and methods used in determining the fair value in order to determine the classification of securities in the fair value hierarchy.

The Company did not hold any Level 3 marketable investments as of June 30, 2023 or December 31, 2022. During the six months ended June 30, 2023 and 2022, the Company did not have any transfers between Level 1, Level 2 or Level 3 of the fair value hierarchy. Additionally, the Company did not have any financial assets and liabilities measured at fair value on a non-recurring basis as of June 30, 2023 or December 31, 2022.

Royalty Obligations

In March 2005, the Company entered into a license agreement that requires the Company to make minimum royalty payments to the licensor on a quarterly basis. In July 2019, the Company amended the license agreement to extend its term for an additional ten years and to increase the required minimum annual royalty payments by $0.2 million. As of both June 30, 2023 and December 31, 2022, the amended license agreement required minimum quarterly royalty payments of $0.3 million. Unless terminated earlier, the term of the amended license agreement shall expire June 30, 2029.

In April 2012, the Company entered into an agreement that requires the Company to pay, on a quarterly basis, a 5% royalty on sales of products covered under applicable patents. The first commercial sale of covered products occurred in April 2014. Unless terminated earlier, the royalty term for each applicable product shall continue for fifteen years following the first commercial sale of such patented product, or when the applicable patent covering such product has expired, whichever is sooner.

Royalty expense included in cost of revenue for the three months ended June 30, 2023 and 2022 was $0.7 million and $0.6 million, respectively, and for the six months ended June 30, 2023 and 2022, was $1.3 million and $1.2 million, respectively.

Contingencies

From time to time, the Company may have certain contingent liabilities that arise in the ordinary course of business. 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.

Indemnification

The Company enters into standard indemnification arrangements in the ordinary course of business. In many such arrangements, the Company agrees to indemnify, hold harmless, and reimburse the indemnified parties for losses suffered or incurred by the indemnified parties 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 Company also agrees to indemnify many indemnified parties for product defect and similar claims. 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 Company has not incurred costs to defend lawsuits or settle claims related to these indemnification agreements. No liability associated with any of these indemnification requirements has been recorded to date.

Litigation

From time to time, the Company is subject to other claims and assessments in the ordinary course of business. The Company is not currently a party to any such litigation matter that, individually or in the aggregate, is expected to have a material adverse effect on the Company’s business, financial condition, results of operations or cash flows.

Stockholder's Equity

9. Stockholders’ Equity

Stock-based Compensation

Stock-based compensation expense is associated with restricted stock units (“RSUs”), RSUs with performance conditions (“PSUs”), stock options, and the Company’s Employee Stock Purchase Plan.

Certain RSUs granted to senior management during the three months ended March 31, 2023, will vest subject to the achievement of pre-established financial performance targets for the year ending December 31, 2023, and continued service. The fair value of these PSUs is based on the closing price of the Company's common stock on the date of grant. Stock-based compensation costs associated with these PSUs are recognized over the requisite service period of 4.25 years using graded

vesting which results in more accelerated expense recognition compared to traditional time-based vesting over the same vesting period. Each reporting period, the Company monitors the probability of achieving the performance targets and may adjust periodic stock-based compensation expense based on its determination of the likelihood of achieving these performance targets and the estimated number of shares of common stock that will vest. The actual number of PSUs awarded is based on the actual performance during the performance period compared to the performance targets.

The following table sets forth the stock-based compensation expense included in the Company’s condensed consolidated statements of operations for the three and six months ended June 30, 2023 and 2022 (in thousands):

	Three Months Ended June 30,				Six Months Ended June 30,

As of June 30, 2023, total unrecognized compensation cost related to unvested share-based compensation arrangements, excluding PSUs, was $71.4 million, which is expected to be recognized over a weighted average period of 2.8 years.

As of June 30, 2023, total unrecognized compensation cost related to unvested PSU share-based compensation arrangements was $15.8 million, which is expected to be recognized over a weighted average period of 3.7 years.

The total stock-based compensation cost capitalized in inventory was $2.1 million and $2.2 million as of June 30, 2023 and December 31, 2022, respectively.

Accumulated Other Comprehensive Income (Loss)

10. Accumulated Other Comprehensive Income (Loss)

Other comprehensive income (loss) consists of two components: unrealized gains or losses on the Company’s available-for-sale marketable investments and gains or losses from foreign currency translation adjustments. Until realized and reported as a component of consolidated net income (loss), these comprehensive income (loss) items accumulate and are included within accumulated other comprehensive income (loss). Unrealized gains and losses on the Company’s marketable investments are reclassified from accumulated other comprehensive income (loss) into earnings when realized upon sale, and are determined based on specific identification of securities sold. Gains and losses from the translation of assets and liabilities denominated in non-U.S. dollar functional currencies are included in accumulated other comprehensive income (loss).

Income Taxes

11. Income Taxes

The Company’s income tax expense (benefit), deferred tax assets and liabilities, and reserves for unrecognized tax benefits reflect management’s best assessment of estimated current and future taxes to be paid. The Company is subject to income taxes in both the United States and foreign jurisdictions. Significant judgment and estimates are required in determining the consolidated income tax expense (benefit).

During interim periods, the Company generally utilizes the estimated annual effective tax rate (“AETR”) method which involves the use of forecasted information. Under the AETR method, the provision is calculated by applying the estimated AETR for the full fiscal year to “ordinary” income or loss (pretax income or loss excluding unusual or infrequently occurring discrete items) for the reporting period. Jurisdictions with tax assets for which the Company believes a tax benefit cannot be realized are excluded from the computation of its AETR.

The Company’s provision for income taxes for the three months ended June 30, 2023 was $0.6 million, which was primarily due to tax expenses attributable to its worldwide profits offset by excess tax benefits from stock-based compensation attributable to its U.S. jurisdiction. The Company’s provision for income taxes for the three months ended June 30, 2022 was $2.5 million, which was primarily due to tax deficiencies (shortfalls) expenses from stock-based compensation attributable to its U.S. jurisdiction as a result of stock price fluctuation, offset by tax benefits attributable to its worldwide losses. The Company’s effective tax rate changed to 2.9% for the three months ended June 30, 2023 from (215.9)% for the three months ended June 30, 2022, primarily due to small tax expenses over relatively large worldwide profits in 2023 comparing to large tax expenses over relatively small worldwide losses in 2022.

The Company’s provision for income taxes for the six months ended June 30, 2023 was $0.7 million, which was primarily due to tax expenses attributable to its worldwide profits offset by excess tax benefits from stock-based compensation attributable to its U.S. jurisdiction. The Company’s benefit from income taxes for the six months ended June 30, 2022 was $2.7 million, which was primarily due to tax benefits attributable to its worldwide losses, offset by tax deficiencies (shortfall) expenses from stock-based compensation attributable to its U.S. jurisdiction as a result of stock price fluctuation. The Company’s effective tax rate changed to 2.4% for the six months ended June 30, 2023 from 42.5% for the six months ended June 30, 2022, primarily due to small tax expenses over relatively large worldwide profits in 2023 comparing to large tax benefits over relatively small worldwide losses in 2022.

Significant domestic deferred tax assets (“DTAs”) were generated in recent years, primarily due to excess tax benefits from stock option exercises and vesting of restricted stock units. The Company evaluates all available positive and negative evidence, objective and subjective in nature, in each reporting period to determine if sufficient taxable income will be generated to realize the benefits of its DTAs and, if not, a valuation allowance to reduce the DTAs is recorded.

As of June 30, 2023 and 2022, the Company maintains a valuation allowance against its Federal Research and Development Tax Credit DTAs as the Company could not conclude at the required more-likely-than-not level of certainty, that the benefit of these tax attributes would be realized prior to expiration. The Company intends to continue maintaining this full valuation allowance until there is sufficient evidence to reverse it. However, considering current earnings and anticipated future earnings, as well as the impact of IRC Section 174 requiring qualified research expenditures to be capitalized and amortized over 5 or 15 years, the Company anticipates net operating loss (“NOL”) utilization may be accelerated. As a consequence, the Company believes there is a reasonable possibility that sufficient positive evidence may become available to conclude this valuation allowance may no longer be needed within the next 12 months. Release of the valuation allowance will result in the recognition of Federal Research and Development Tax Credit DTAs and a decrease to income tax expenses for the period in which the release is recorded. The exact timing and amount of the valuation allowance release are highly dependent on the level

of taxable income in future years. The Company will continue to closely monitor the need for this valuation allowance in each subsequent reporting period.

As of June 30, 2023 and 2022, the company maintains a full valuation allowance against its California DTAs as the Company does not expect to generate sufficient future taxable income in California to realize the tax benefit due to the computation of California taxes under the single sales factor and non-conformity of the Section 174 capitalization rule.

The Company maintains that all foreign earnings, with the exception of a portion of the earnings of its German subsidiary, are permanently reinvested outside the United States and therefore deferred taxes attributable to such earnings are not provided for in the Company’s condensed consolidated financial statements as of June 30, 2023.

Earnings Per Share [Abstract]

Net Income (Loss) per Share

12. Net Income (Loss) per Share

The Company computed basic net income (loss) per share based on the weighted average number of shares of common stock outstanding during the period. The Company computed diluted net income (loss) per share based on the weighted average number of shares of common stock outstanding plus potentially dilutive common stock equivalents outstanding during the period using the treasury stock method. For the purposes of this calculation, stock options, restricted stock units and stock sold through the Company’s employee stock purchase plan are considered common stock equivalents.

A reconciliation of the numerator and denominator used in the calculation of the basic and diluted net income (loss) per share is as follows (in thousands, except share and per share amounts):

China Distribution and Technology Licensing Agreement

In December 2020, the Company entered into a distribution and technology licensing arrangement with its existing distribution partner in China. In addition to modifying the Company’s standard distribution agreement with its partner in China, the Company agreed to license the technology for certain products to its partner in China to permit the manufacturing and commercialization of such products in China as well as provide certain regulatory support. During the three months ended March 31, 2022, the Company further amended the distribution agreement and entered into an additional license agreement, pursuant to which the Company agreed to license the technology for additional products to its partner in China on substantially the same terms as the existing license agreement. Apart from the standard distribution agreement, the Company will receive fixed payments upon transferring its distinct licensed technology and providing related regulatory support and royalty payments on the down-stream sale of the licensed products.

Performance Obligations

Delivery of products - The Company’s contracts with customers typically contain a single performance obligation, delivery of the Company’s products. Satisfaction of that performance obligation occurs when control of the promised goods transfers to the customer, which is generally upon shipment for non-consignment sale agreements and upon utilization for consignment sale agreements.

Payment terms - The Company’s payment terms vary by the type and location of our customer. The timing between fulfillment of performance obligations and when payment is due is not significant and does not give rise to financing transactions. The Company did not have any contracts with significant financing components as of June 30, 2023.

Product returns - The Company may allow customers to return products purchased at the Company’s discretion. The Company estimates the amount of its product sales that may be returned by its customers and records this estimate as a reduction of revenue in the period in which the related product revenue is recognized. The Company currently estimates product return liabilities using its own historic sales information, trends, industry data, and other relevant data points.

Warranties - The Company offers its standard warranty to all customers and it is not available for sale on a standalone basis. The Company’s standard warranty represents its guarantee that its products function as intended, are free from defects, and comply with agreed-upon specifications and quality standards. This assurance does not constitute a service and is not a separate performance obligation.

Transaction Price

Revenue is recorded at the net sales price, which includes estimates of variable consideration such as product returns utilizing historical return rates, rebates, discounts, and other adjustments to net revenue. To the extent the transaction price includes variable consideration, the Company estimates the amount of variable consideration that should be included in the transaction price. When determining if variable consideration should be constrained, management considers whether there are

factors that could result in a significant reversal of revenue and the likelihood of a potential reversal. Variable consideration is included in revenue only to the extent that it is probable that a significant reversal of the revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. These estimates are reassessed each reporting period. During the three and six months ended June 30, 2023, the Company made no material changes in estimates for variable consideration. When the Company performs shipping and handling activities after control of goods is transferred to the customer, they are considered as fulfillment activities, and costs are accrued for when the related revenue is recognized. Taxes collected from customers relating to product sales and remitted to governmental authorities are excluded from revenues.

Contract liabilities, net

The following information summarizes the Company’s contract assets and liabilities, net as of June 30, 2023 and December 31, 2022 (in thousands):

	June 30, 2023		December 31, 2022
Contract liabilities, net	$	7,883	$	8,783

Contract liabilities represents amounts that the Company has already invoiced and are ultimately expected to be recognized as revenue, but for which not all revenue recognition criteria have been met and is recognized as the associated performance obligations are satisfied. Contract assets for the periods presented primarily represent the difference between the revenue that was recognized based on the relative standalone selling price of the related performance obligations satisfied and the contractual billing terms in the arrangements. Revenue recognized during the three and six months ended June 30, 2023 relating to contract liabilities as of March 31, 2023 and December 31, 2022 was $0.4 million and $0.9 million, respectively.

Summary of Significant Accounting Policies (Policies)

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation and Consolidation

The accompanying condensed consolidated balance sheet as of June 30, 2023, the condensed consolidated statements of operations, the condensed consolidated statements of comprehensive income (loss), and the condensed consolidated statements of stockholders’ equity for the three and six months ended June 30, 2023 and 2022, and the condensed consolidated statements of cash flows for the six months ended June 30, 2023 and 2022 are unaudited. The unaudited condensed consolidated financial statements included herein have been prepared by the Company in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and the applicable rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”) for interim financial information. Accordingly, they do not include all of the information and notes required by U.S. GAAP for complete financial statements. The condensed consolidated balance sheet data as of December 31, 2022 was derived from the audited financial statements as of that date.

The unaudited condensed consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements and, in the opinion of management, reflect all adjustments of a normal recurring nature considered necessary to state fairly the Company’s financial position as of June 30, 2023, the results of its operations for the three and six months ended June 30, 2023 and 2022, the changes in its comprehensive income (loss) and stockholders’ equity for the three and six months ended June 30, 2023 and 2022, and its cash flows for the six months ended June 30, 2023 and 2022. The results for the three and six months ended June 30, 2023 are not necessarily indicative of the results that may be expected for the year ending December 31, 2023 or for any other future annual or interim period.

The information included in this Quarterly Report on Form 10-Q should be read in conjunction with the audited consolidated financial statements and notes thereto for the fiscal year ended December 31, 2022, included in the Company’s Annual Report on Form 10-K. There have been no changes to the Company’s significant accounting policies during the six months ended June 30, 2023, as compared to the significant accounting policies described in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022, except for the granting of restricted stock units with performance conditions to senior management during the three months ended March 31, 2023. Refer to Note “9. Stockholders’ Equity” for information on the Company’s accounting policy.

Consolidation

The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.

Use of Estimates

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities and equity accounts; disclosure of contingent assets and liabilities at the date of the financial statements; and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, the Company evaluates its estimates, including those related to marketable investments, allowances for credit losses, the amount of variable consideration included in the transaction price, warranty reserve, valuation of inventories, useful lives of property and equipment, intangibles, operating and financing lease right-of-use (“ROU”) assets and liabilities, income taxes, contingent consideration and other contingencies, including the probability of achieving performance targets associated with equity awards with performance conditions, among others. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under 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 data. Actual results could differ from those estimates.

Segments

Segments The Company determined its operating segment on the same basis that it uses to evaluate its performance internally. The Company has one business activity: the design, development, manufacturing and marketing of innovative medical products, and operates as one operating segment. The Company’s chief operating decision-maker, its Chief Executive Officer, reviews its consolidated operating results for the purpose of allocating resources and evaluating financial performance.

Marketable Investments

Marketable InvestmentsThe Company’s marketable investments have been classified and accounted for as available-for-sale.

Performance Shares

The fair value of these PSUs is based on the closing price of the Company's common stock on the date of grant. Stock-based compensation costs associated with these PSUs are recognized over the requisite service period of 4.25 years using graded vesting which results in more accelerated expense recognition compared to traditional time-based vesting over the same vesting period. Each reporting period, the Company monitors the probability of achieving the performance targets and may adjust periodic stock-based compensation expense based on its determination of the likelihood of achieving these performance targets and the estimated number of shares of common stock that will vest. The actual number of PSUs awarded is based on the actual performance during the performance period compared to the performance targets.
