Notes to Condensed Consolidated Financial Statements

(unaudited)

1. Organization and Description of Business

Penumbra, Inc. (the “Company”) is a global healthcare company focused on innovative therapies. The Company designs, develops, manufactures and markets novel products and has a broad portfolio that addresses challenging medical conditions in markets with significant unmet need.

2. Summary of Significant Accounting Policies

Basis of Presentation and Consolidation

The accompanying condensed consolidated balance sheet as of September 30, 2021, 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 nine months ended September 30, 2021 and 2020, and the condensed consolidated statements of cash flows for the nine months ended September 30, 2021 and 2020 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, 2020 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 September 30, 2021, the results of its operations for the three and nine months ended September 30, 2021 and 2020, the changes in comprehensive income (loss) and stockholders’ equity for the three and nine months ended September 30, 2021 and 2020, and the cash flows for the nine months ended September 30, 2021 and 2020. The results for the three and nine months ended September 30, 2021 are not necessarily indicative of the results that may be expected for the year ending December 31, 2021 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 year ended December 31, 2020, 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 nine months ended September 30, 2021, 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, 2020.

The condensed consolidated financial statements include the accounts of the Company, its wholly-owned subsidiaries and its majority-owned subsidiary. The portion of equity and consolidated net income not attributable to the Company is considered non-controlling interest and is classified separately in the condensed consolidated financial statements. Any subsequent changes in the Company’s ownership interest while the Company retains its controlling interest in its majority-owned subsidiary will be accounted for as equity transactions. 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, operating and financing lease right-of-use (“ROU”) assets and liabilities, income taxes, contingent consideration and other contingencies, 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 devices, and

(unaudited)

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.

Recently Adopted Accounting Standards

On January 1, 2021, the Company adopted ASU No. 2019-12, Income Taxes— Simplifying the Accounting for Income Taxes (“ASU 2019-12”). This new standard removes certain exceptions for recognizing deferred taxes of foreign investments, the incremental approach to performing intraperiod allocation, and calculating income taxes for year-to-date interim period losses when such losses exceed anticipated full year losses. The standard also adds guidance to reduce complexity in certain areas, including accounting for franchise taxes that are partially based on income, transactions with a government that result in a step up in goodwill tax basis, enacted tax law changes impact during interim periods, and allocation of taxes to members of a consolidated group which are not subject to tax. The adoption of ASU 2019-12 did not have a material impact on the consolidated financial statements during the nine months ended September 30, 2021.

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 September 30, 2021 and December 31, 2020 (in thousands):

As of September 30, 2021, the total amortized cost basis of the Company’s impaired available-for-sale securities exceeded its fair value by a nominal amount. The Company reviewed its impaired available-for-sale securities and concluded that the decline in fair value was not related to credit losses and is recoverable. Accordingly, during the three and nine months ended September 30, 2021 no allowance for credit losses was recorded and instead the unrealized losses are reported as a component of accumulated other comprehensive (loss) income.

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.

(unaudited)

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 September 30, 2021 or December 31, 2020. During the nine months ended September 30, 2021 and 2020, 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 September 30, 2021 or December 31, 2020.

The following tables set forth the Company’s financial assets measured at fair value by level within the fair value hierarchy as of September 30, 2021 and December 31, 2020 (in thousands):

The customer relationships and other intangible assets subject to amortization relate to the acquisition of Crossmed during the third quarter of 2017. The gross carrying amount and accumulated amortization of these intangible assets are subject to foreign currency translation effects. The Company’s $5.3 million trade secrets and processes intangible asset was recognized in connection with a royalty buyout agreement entered into during the first quarter of 2018.

The following table presents the amortization expense recorded related to the Company’s finite-lived intangible assets for the three and nine months ended September 30, 2021 and September 30, 2020 (in thousands):

Licensed technology

During the third quarter of 2017, the Company entered into an exclusive technology license agreement (the “License Agreement”) that required the Company to pay an upfront payment to the licensor of $2.5 million and future revenue milestone-based payments on sales of products covered by the licensed intellectual property. The Company accounted for the transaction as an asset acquisition and recorded an indefinite-lived intangible asset as it was determined to have alternative future use. The Company recorded an indefinite-lived intangible asset equal to the total payments made and expected to be made under the License Agreement and a corresponding contingent liability for the probable future milestone payments not yet paid.

Indefinite-lived intangible assets are tested for impairment annually during the fourth quarter or more frequently if events or changes in circumstances between annual tests indicate that it is more likely than not that the asset is impaired. As a result of a triggering event in July 2020 that provided additional information about a condition that existed on the balance sheet date, the Company determined that an impairment existed as of June 30, 2020. As a result, the Company wrote-off the full carrying value of the indefinite-lived intangible asset and its related contingent liabilities, and recognized an impairment loss of $2.5 million in research and development expense in the consolidated statement of operations as of September 30, 2020.

At the end of each reporting period the Company had also adjusted the contingent liabilities to reflect the amount of future milestone payments that were probable to be paid. Prior to the commercialization of products utilizing the underlying technology, any changes in the contingent liability were recorded as an adjustment between the liability balances and the gross

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 was set to mature on April 23, 2021. The Company entered into an amended one-year 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 during the three months ended March 31, 2021.

The amended Credit Agreement extended the maturity date from April 23, 2021 to February 21, 2022 and has substantially the same terms and conditions as the prior credit agreement with certain changes including the exclusion of certain one-time charges and expenses incurred during the fiscal quarters ended September 30, 2020 and December 31, 2020 from the calculation of the financial covenants, reductions in interest rate floors applicable to revolving loans and other changes to borrowing mechanics under the Credit Agreement.

The Credit Agreement requires the Company to maintain a minimum fixed charge coverage ratio and to not exceed a maximum leverage ratio. As of September 30, 2021, the Company was in compliance with these requirements.

As of September 30, 2021 and December 31, 2020, there were no borrowings outstanding under the amended Credit Agreement.

8. Leases

9. 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 September 30, 2021 and December 31, 2020, 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 September 30, 2021 and 2020, was $0.6 million and $0.7 million, respectively, and for the nine months ended September 30, 2021 and 2020, was $1.7 million and $1.8 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.

On January 15, 2021, a putative securities class action complaint was filed against the Company and its CEO, Adam Elsesser, and Executive Vice President, Global Marketing and Public Relations, Gita Barry, on behalf of a single shareholder in the U.S. District Court for the Northern District of California, asserting claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and Rule 10b-5 promulgated thereunder. The complaint sought unspecified damages on behalf of a purported class that would comprise all individuals who purchased or otherwise acquired the Company's common stock between August 3, 2020 and December 15, 2020. The complaint alleged securities law violations based on allegedly misleading statements and/or omissions made in connection with the Company’s JET 7 Xtra Flex product. On March 16, 2021, the plaintiff voluntarily dismissed the complaint without prejudice.

The Company is not currently a party to any 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.

11. Accumulated Other Comprehensive Income

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. Unrealized gains and losses on the Company’s marketable investments are reclassified from accumulated other comprehensive income 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.

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 into earnings affect the Company’s condensed consolidated statements of operations and condensed consolidated statements of comprehensive income (loss) (in thousands):

12. Income Taxes

The Company’s income tax expense, 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.

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. In addition, the Company excluded the unusual and infrequent anticipated one-time expenses associated with the acquisition (See Note “15. Subsequent Events” to our condensed consolidated financial statements in Part I, Item 1 of this Quarterly Report on Form 10-Q for more information) from the full year forecast when computing the AETR for the three and nine months ended September 30, 2021.

The Company’s income taxes for the three and nine months ended September 30, 2021 was $0.2 million of tax benefit and $3.2 million of tax expense, respectively, compared to $9.9 million and $15.6 million of tax benefit for the three and nine months ended September 30, 2020, respectively. The Company’s tax benefit or expense for 2021 was primarily due to tax expense attributable to worldwide profit, offset by excess tax benefit from stock-based compensation attributable to U.S. jurisdiction, compared to the tax benefit attributable to worldwide loss as a result of the COVID-19 pandemic impact combined with excess tax benefit from stock-based compensation attributable to the U.S. jurisdiction in 2020.

The Company’s effective tax rate was (3.2)% and 10.5% for the three and nine months ended September 30, 2021, respectively, compared to 49.9% and 41.6% for the three and nine months ended September 30, 2020, respectively. The Company’s change in effective tax rate was primarily attributable to small tax benefit or expense over relatively large worldwide profit for the three and nine months ended September 30, 2021, when compared to large tax benefit over relatively small worldwide loss for the three and nine months ended September 30, 2020.

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. 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 September 30, 2021 and 2020, the Company maintains a valuation allowance against its Federal Research and Development Tax Credit and California 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. As of September 30, 2021 and 2020, the Company also maintains a valuation allowance against DTAs acquired from MVI which are subject to Separate Return Limitation Year (“SRLY”) rules that limit the utilization of the pre-acquisition tax attributes to offset future taxable income solely generated by MVI.

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 are not provided for in the Company’s condensed consolidated financial statements as of September 30, 2021.

13. Net Income (Loss) Attributable to Penumbra, Inc. Per Share

The Company computed basic net income (loss) attributable to Penumbra, Inc. per share based on the weighted average number of shares of common stock outstanding during the period. The Company computed diluted net income (loss) attributable to Penumbra, Inc. 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, 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) attributable to Penumbra, Inc. per share is as follows (in thousands, except share and per share amounts):


	Three Months Ended September 30,				Nine Months Ended September 30,
	2021		2020		2021		2020
Numerator:
Net income (loss) attributable to Penumbra, Inc.	$	8,850	$	(8,815)	$	29,917	$	(19,350)



Denominator:
Weighted average shares used to compute net income (loss) attributable to common stockholders:
Basic	36,617,961		36,207,716		36,532,822		35,568,591
Potential dilutive stock-based options and awards	993,394		—		1,059,273		—

Diluted	37,611,355		36,207,716		37,592,095		35,568,591
Net income (loss) attributable to Penumbra, Inc. per share:
Basic	$	0.24	$	(0.24)	$	0.82	$	(0.54)
Diluted	$	0.24	$	(0.24)	$	0.80	$	(0.54)

For the three months ended September 30, 2021 and 2020, outstanding stock-based awards of 6 thousand and 1.8 million shares, respectively, and for the nine months ended September 30, 2021 and 2020, outstanding stock-based awards of 27 thousand and 1.9 million shares, respectively, were excluded from the computation of diluted net income (loss) attributable to Penumbra, Inc. per share because their effect would have been anti-dilutive.

14. 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 Chinese partner, the Company agreed to license the technology for certain products to its Chinese partner to permit the manufacturing and commercialization of such products in China as well as provide certain regulatory support. Apart from the standard distribution agreement, the Company will receive fixed payments upon transferring its distinct licensed technology and providing related regulatory support and receive royalty payments on the downstream sales 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 September 30, 2021.

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 as required. During the three and nine months ended September 30, 2021, 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.

15. Subsequent Events

On October 1, 2021 the Company closed (the “Closing”) the acquisition of Sixense Enterprises Inc. (“Sixense”) pursuant to the Agreement and Plan of Merger, dated September 17, 2021 (the “Merger Agreement”) among the Company, Sixense, Seychelles Merger Corporation, a wholly owned subsidiary of the Company, and a stockholders’ agent (the “Merger”).

Sixense, a privately held company, specializes in enterprise use of virtual reality hardware and software and has been an integral partner on the development of the Company’s REAL System portfolio. This acquisition allows the Company to streamline its efforts and collaborate more closely on its immersive therapeutics offerings.

At the Closing and as consideration for the Merger, all outstanding shares of Sixense capital stock were cancelled in exchange for the right to receive an aggregate amount of 661,877 shares of the Company’s common stock, representing purchase consideration to be calculated by using the closing price of the Company's common stock on October 1, 2021. Additionally, at the closing, the Company converted all stock options held by Sixense service providers that would continue as service providers after the Merger into fully vested options to purchase an aggregate amount of 447,017 shares of the Company’s common stock. These converted options to purchase the Company’s common stock, which are attributable to precombination vesting, will represent purchase consideration based on the fair value of these replacement awards as of October 1, 2021. The shares of the Company’s common stock issued pursuant to the terms of the Merger Agreement were issued in reliance upon the exemption from registration available under Section 4(a)(2) of the Securities Act of 1933, as amended.

Given the short period of time from the close of the acquisition to the filing of this Form 10-Q, the Company is in the process of compiling the required information to complete the initial accounting for the Merger. As a result certain information, including the fair value of the consideration transferred, its allocation to the major classes of assets acquired and liabilities assumed and other required disclosures, will be included in the Company’s Annual Report on Form 10-K for the year ending December 31, 2021.

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. 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 and vascular. We have successfully developed, obtained regulatory clearance or approval for, and introduced products into the neurovascular market since 2007, vascular market since 2013 and neurosurgical market since 2014, 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 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 two key markets, we developed products that fall into the following broad product offering families:

Our neuro products fall into five broad product families:

•Neuro thrombectomy - Penumbra System, including Penumbra JET, ACE 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, DDC and PX SLIM

•Neurosurgical - Artemis Neuro Evacuation Device

•Virtual Reality Platform - REAL Immersive System

Our vascular products fall into two broad product families:

•Vascular thrombectomy - INDIGO System designed for mechanical thrombectomy, including aspiration catheters, separators, aspiration pump and accessories and Lightning, our next-generation aspiration system for peripheral thrombectomy

Table of Contents

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

We support healthcare providers, hospitals and clinics in more than 100 countries. In the nine months ended September 30, 2021 and 2020, 29.5% and 28.0% 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 $543.6 million and $393.5 million for the nine months ended September 30, 2021 and 2020, respectively, an increase of $150.1 million. We generated operating income of $32.6 million and an operating loss of $37.2 million for the nine months ended September 30, 2021 and 2020, respectively.

COVID-19 Pandemic

In March 2020, the World Health Organization declared the outbreak of COVID-19 as a pandemic, which continues to spread throughout the U.S. and the world. In response, governments have issued orders restricting certain activities, and while our business falls within the category of healthcare operations, which are essential businesses permitted to continue operating during the COVID-19 pandemic, we have experienced, and expect to continue to experience, disruptions to our operations as a result of the pandemic. For example, 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 during the pandemic. Some of Penumbra’s medical devices are used in certain procedures that the United States Centers for Medicare & Medicaid Services (“CMS”) has indicated are “high-acuity” procedures that should not be postponed during the pandemic in its March 18, 2020 recommendations, while other Penumbra devices are used in elective procedures that physicians may consider postponing. Many of the procedures in which our vascular products are used are elective in nature, whereas procedures in which our neuro products are used, such as stroke, tend to be more emergent in nature.

The impact of COVID-19 on our business remains fluid, and we continue to actively monitor the dynamic situation. We will continue to undertake the following specific actions and strategic priorities to navigate the pandemic:

•We have made 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 we are committed to continue meeting demand for our essential devices, we have implemented social distancing and other measures to protect the health and safety of our employees, which have reduced, and may continue to reduce, our manufacturing capacity.

•We further strengthened our liquidity position by entering into a Credit Agreement (the “Credit Agreement”) on April 24, 2020, 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. This revolving line of credit provides access to capital beyond the $266.9 million in cash, cash equivalents and marketable investments on our balance sheet as of September 30, 2021, and we believe this will allow us to both navigate the current environment and emerge in a strong liquidity position after the pandemic. During the three months ended March 31, 2021, we entered into an amended one-year 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 amended Credit Agreement extended the maturity date from April 23, 2021 to February 21, 2022 and has substantially the same terms and conditions as the prior credit agreement with certain changes including the exclusion of certain one-time charges and expenses incurred during the fiscal quarters ended September 30, 2020 and December 31, 2020 from the calculation of the financial covenants, reductions in interest rate floors applicable to revolving loans and other changes to borrowing mechanics under the Credit Agreement. As of September 30, 2021, the Company was in compliance with the requirements in the amended Credit Agreement. As of September 30, 2021, there were no borrowings outstanding under the Credit Agreement.

•We will continue to prioritize investments in our production capacity and flexibility, commercial channels, preparation for new product launches, and new product developments to help patients.

While we began to see positive trends in certain areas of our business in May 2020, we remain mindful of the negative impacts on business trends we experienced in April 2020 due to the COVID-19 pandemic. The general impact of COVID-19 on our business has been negative and we are unable to reliably predict the full impact that the COVID-19 pandemic 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

Table of Contents

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 year ended December 31, 2020. 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.

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 we expect will continue to negatively affect, our revenues and results of operations. Due to these impacts and measures, we may experience significant and unpredictable fluctuations in demand for certain of our products as hospital customers re-prioritize the treatment of patients and distributors adjust their operations to support the current demand level.

•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 who use our products.

•We must continue to successfully introduce new products that gain acceptance with specialist physicians 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 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 impact of COVID-19, 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. Due to the impact of the COVID-19 pandemic on our business during the quarter ended September 30, 2020, comparisons of our results of operations for the three and nine months ended September 30, 2021 to the comparable period of the prior year may not be indicative of our performance in future periods as we saw an increase in elective procedures during the nine months ended September 30, 2021 as COVID-19 vaccinations increased in the U.S.

Components of Results of Operations

Revenue. We sell our 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 and 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.

(Benefit from) Provision For 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.

Total	$	190,117	$	151,076	$	39,041	25.8	%

Revenue increased $39.0 million, or 25.8%, to $190.1 million in the three months ended September 30, 2021, from $151.1 million in the three months ended September 30, 2020. Overall revenue growth is primarily due to an increase in sales of new and existing products within our vascular and neuro businesses, as well as a higher number of elective procedures performed as COVID-19 vaccination rates increased. Given the current state of vaccinations and the spread of new variants of the virus, it is possible that the increase in elective cases will begin to normalize in future quarters.

Revenue from our vascular products increased $30.3 million, or 40.3%, to $105.5 million in the three months ended September 30, 2021, from $75.2 million in the three months ended September 30, 2020. This increase was driven by sales of our vascular thrombectomy products and peripheral embolization products, which globally increased by 55.4% and 22.2%, respectively in the three months ended September 30, 2021. These increases were primarily due to higher sales volume as a result of sales of new products, further market penetration of our existing products, and an increase in the number of elective procedures performed. Prices for our vascular products remained substantially unchanged during the period.

Revenue from our neuro products increased $8.7 million, or 11.5%, to $84.7 million in the three months ended September 30, 2021, from $75.9 million in the three months ended September 30, 2020. This increase in revenue from our neuro products was primarily attributable to increased revenue in China, sales of new products, and further market penetration of our existing

products. These increases were driven by an increase in sales of our neuro access products, neuro embolization products and neuro thrombectomy products which globally increased by 34.3%, 8.1% and 1.7%, respectively, in the three months ended September 30, 2021. Prices for our neuro products remained substantially unchanged during the period.

Gross margin increased 2.9 percentage points to 63.1% in the three months ended September 30, 2021, from 60.2% in the three months ended September 30, 2020, primarily due to benefits from higher volume and stable product mix. Gross margin is impacted by our ability to scale production capacity to support our expanding portfolio of products as well as our continued investments in COVID-19 related safety measures. As such, as we continue to accelerate investments in our production capacity, our gross margin may be negatively impacted in the short term.

R&D expenses decreased by $18.2 million, or 52.1%, to $16.7 million in the three months ended September 30, 2021, from $34.9 million in the three months ended September 30, 2020. The decrease was primarily due to $13.2 million of one-time, non-recurring personnel-related expenses associated with the launch of our Lightning product in the third quarter of 2020 and a $2.6 million decrease in product development and testing costs.

We have made investments, and plan to continue to make investments, in the development of our products, which may include hiring additional research and development employees. As part of our ongoing investment in the development of our products, we are anticipating future payments 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 $18.2 million, or 23.9%, to $94.4 million in the three months ended September 30, 2021, from $76.2 million in the three months ended September 30, 2020. The increase was primarily due to a $5.9 million increase in personnel-related expenses driven by an increase in headcount and related expenses to support our growth, a $3.5 million increase in travel-related expenses as most domestic travel and other in-person activities returned to pre-COVID-19 levels in the current period, a $3.4 million increase in cost related to marketing events, and a $1.9 million increase in infrastructure costs.

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. As part of our ongoing investment in our growth, we are anticipating one-time expenses associated with the Sixense acquisition (See Note “15. Subsequent Events” to our condensed consolidated financial statements in Part I, Item 1 of this Quarterly Report on Form 10-Q for more information). 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 in infrastructure to support the business.

Provision for (benefit from) income taxes	$	(249)		$	(9,855)		$	9,606	(97.5)	%
Effective tax rate	(3.2)		%	49.9		%

Our benefit from income taxes was $0.2 million for the three months ended September 30, 2021, which was primarily due to tax expense attributable to our worldwide profit, offset by excess tax benefit from stock-based compensation attributable to our U.S. jurisdiction. Our benefit from income taxes was $9.9 million for the three months ended September 30, 2020, which was primarily due to tax benefit attributable to our worldwide loss as a result of the COVID-19 pandemic impact, combined with excess tax benefit from stock-based compensation attributable to our U.S. jurisdiction. The effective tax rate was (3.2)% for the three months ended September 30, 2021, compared to 49.9% for the three months ended September 30, 2020. Our change in effective tax rate was primarily attributable to small tax benefit over relatively large worldwide profit for the three months ended September 30, 2021, when compared to large tax benefit over relatively small worldwide loss for the three months ended September 30, 2020. In addition, the anticipated payments related to research and development milestones and one-time expenses associated with the Sixense acquisition may result in a future tax benefit.

Provision For (Benefit from) Income Taxes

	(in thousands, except for percentages)
Provision for (benefit from) income taxes	$	3,196		$	(15,618)		$	18,814	(120.5)	%
Effective tax rate	10.5		%	41.6		%

Our provision for income taxes was $3.2 million for the nine months ended September 30, 2021, which was primarily due to tax expense attributable to our worldwide profit, offset by excess tax benefit from stock-based compensation attributable to our U.S. jurisdiction. Our benefit from income taxes was $15.6 million for the nine months ended September 30, 2020, which was primarily due to tax benefit attributable to our worldwide loss as a result of the COVID-19 pandemic impact, combined with excess tax benefit from stock-based compensation attributable to our U.S. jurisdiction. The effective tax rate was 10.5% for the nine months ended September 30, 2021, compared to 41.6% for the nine months ended September 30, 2020. Our change in effective tax rate was primarily attributable to small tax expense over relatively large worldwide profit for the nine months ended September 30, 2021, when compared to large tax benefit over relatively small worldwide loss for the nine months ended September 30, 2020. In addition, the anticipated payments related to research and development milestones and one-time expenses associated with the Sixense acquisition may result in a future tax benefit.

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 attributable to our worldwide profit or tax benefit attributable to our worldwide losses, and (3) discrete tax adjustments such as excess tax benefits related to stock-based compensation. Our income tax provision is subject to volatility as the amount of excess tax benefits 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. 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.

Liquidity and Capital Resources

As of September 30, 2021, we had $551.9 million in working capital, which included $66.3 million in cash and cash equivalents and $200.6 million in marketable investments. As of September 30, 2021, we held approximately 26.2% of our cash and cash equivalents in foreign entities.

Table of Contents

In June 2020, we issued and sold an aggregate of 865,963 shares of our common stock at a public offering price of $166.00 per share, less the underwriters’ discounts and commissions, pursuant to an underwritten public offering. We received approximately $134.8 million in net cash proceeds from the offering after deducting underwriting discounts and commissions of $8.6 million and other offering expenses of $0.4 million. We intend to use the net proceeds from the offering for general corporate purposes, including working capital, continued development of our products, including research and development and clinical trials, potential acquisitions and other business opportunities. Pending the use of the net proceeds from the offering, we are investing the net proceeds in investment grade, interest bearing securities.

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 during the COVID-19 pandemic, 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, and was set to mature on April 23, 2021. During the three months ended March 31, 2021, we entered into an amended one-year 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 amended Credit Agreement extended the maturity date from April 23, 2021 to February 21, 2022 and has substantially the same terms and conditions as the prior credit agreement with certain changes including the exclusion of certain one-time charges and expenses incurred during the fiscal quarters ended September 30, 2020 and December 31, 2020 from the calculation of the financial covenants, reductions in interest rate floors applicable to revolving loans and other changes to borrowing mechanics under the Credit Agreement. 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 our 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.

While we have strengthened our liquidity position, we cannot reliably estimate the extent to which the COVID-19 pandemic may impact our cash flow from operations in the fourth quarter and beyond.

The following table summarizes our cash and cash equivalents, marketable investments and selected working capital data as of September 30, 2021 and December 31, 2020:

Cash and cash equivalents and restricted cash at end of period	66,290		80,115

Net Cash Provided By (Used In) Operating Activities

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

Net cash provided by operating activities was $18.8 million during the nine months ended September 30, 2021 and consisted of consolidated net income of $27.3 million and non-cash items of $39.6 million, offset by net changes in operating assets and liabilities of $48.0 million. The change in operating assets and liabilities includes an increase in inventories of $45.8 million to support our growth, an increase in prepaid expenses and other current and non-current assets of $7.1 million, an increase in accounts receivable of $7.0 million, and a decrease in accounts payable of $1.2 million. This was partially offset by an increase in accrued expenses and other non-current liabilities of $9.8 million and proceeds of $3.2 million received related to lease incentives from operating leases.

Net cash used in operating activities was $31.2 million during the nine months ended September 30, 2020 and consisted of consolidated net loss of $21.9 million and net changes in operating assets and liabilities of $27.5 million, offset by non-cash items of $18.3 million. The change in operating assets and liabilities includes an increase in inventories of $39.9 million, an increase in accounts receivable of $7.4 million and an increase in prepaid expenses and other current and non-current assets of $6.0 million. This was partially offset by an increase in accrued expenses and other non-current liabilities of $26.1 million.

Net Cash Used In Investing Activities

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

Net cash used in investing activities was $20.4 million during the nine months ended September 30, 2021 and primarily consisted of purchases of marketable investments, net of proceeds from maturities and sales, of $7.2 million, and capital expenditures of $13.1 million.

Net cash used in investing activities was $93.9 million during the nine months ended September 30, 2020 and consisted of purchases of marketable investments, net of proceeds from maturities and sales, of $69.9 million, and capital expenditures of $21.0 million.

Net Cash (Used In) Provided By Financing Activities

Net cash (used in) 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 certain acquisition-related payments, and proceeds from exercises of stock options and issuance of common stock.

Table of Contents

Net cash used in financing activities was $2.1 million during the nine months ended September 30, 2021 and primarily consisted of $10.5 million of payments of employee taxes related to vested restricted stock and restricted stock units and $1.1 million in payments towards finance leases. This was partially offset by proceeds from the issuance of common stock under our employee stock purchase plan of $7.4 million and proceeds from exercises of stock options of $2.2 million.

Net cash provided by financing activities was $132.5 million during the nine months ended September 30, 2020 and primarily consisted of proceeds from the issuance of common stock, net of issuance costs, of $134.8 million, proceeds from the issuance of common stock under our employee stock purchase plan of $5.9 million, and proceeds from exercises of stock options of $4.4 million. This was partially offset by $8.6 million of payments of employee taxes related to vested restricted stock and restricted stock units, $3.1 million in payments towards finance leases, and $0.7 million related to contingent consideration payments made in the first quarter of 2020 in connection with our acquisition of Crossmed in 2017.

Contractual Obligations and Commitments

During the nine months ended September 30, 2021, the Company entered into new leases, and modified existing leases for certain properties. See Note “8. Leases” to our condensed consolidated financial statements in Part I, Item 1 of this Quarterly Report on Form 10-Q for more information regarding our future lease obligations.

During the nine months ended September 30, 2021, we entered into a $7.3 million non-cancelable supply agreement to purchase a fixed amount of materials used in our manufacturing process.

There have been no other material changes to our contractual obligations and commitments as of September 30, 2021 from those disclosed in our Annual Report on Form 10-K for the year ended December 31, 2020.

Off-Balance Sheet Arrangements

We do not have any significant off-balance sheet arrangements or holdings in variable interest entities.

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, 2020.

Recently Issued Accounting Standards

For information with respect to recently issued accounting standards and the impact of these standards on our condensed consolidated financial statements, see Note “2. Summary of Significant Accounting Policies” to our condensed consolidated financial statements in Part I, Item 1 of this Quarterly Report on Form 10-Q.

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 and/or our marketable investments.

Interest Rate Risk. We had cash and cash equivalents of $66.3 million as of September 30, 2021, which consisted of funds held in money market funds, general checking and savings accounts. In addition, we had marketable investments of $200.6 million, which consisted primarily of commercial paper, corporate bonds, 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 our Credit Agreement bear interest at: 1) the adjusted LIBO rate or adjusted EURIBO rate, as applicable,

plus an applicable rate, for euro currency revolving borrowing; or 2) an alternate base rate plus an applicable rate, for revolving borrowing in U.S. Dollars. The United Kingdom’s Financial Conduct Authority, which regulates LIBOR, announced in July 2017 that it intends to phase out LIBOR by the end of 2021. In the event that certain transition events are triggered under our Credit Agreement, interest on our future revolving loans would be determined by a replacement benchmark reference rate.

As of September 30, 2021, 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 attributable to Penumbra, Inc. 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.

We do not believe that inflation and changes in prices had a significant impact on our results of operations as of and for the period ended September 30, 2021.

ITEM 4. CONTROLS AND PROCEDURES.

Evaluation of Disclosure Controls and Procedures

An evaluation as of September 30, 2021 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) 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 Securities and Exchange Commission’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 September 30, 2021.

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 September 30, 2021 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.
