ABIOMED, INC. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

(In thousands, except share data)

Note 1. Nature of Business

ABIOMED, Inc. (the “Company” or “ABIOMED”) is a provider of medical devices that provide circulatory support and oxygenation. Our products are designed to enable the heart to rest by improving blood flow and/or provide sufficient oxygenation to those in respiratory failure. The Company develops, manufactures and markets proprietary products that are designed to enable the heart to rest, heal and recover by improving blood flow and/or performing the pumping function of the heart. The Company’s products are used in the cardiac catheterization lab, or cath lab, by interventional cardiologists and in the heart surgery suite by cardiac surgeons for patients who are in need of hemodynamic support prophylactically or emergently before, during or after angioplasty or heart surgery procedures.

Note 2. Basis of Preparation and Summary of Significant Accounting Policies

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles, or GAAP, for interim financial reporting as found in the Accounting Standards Codification (“ASC”) and Accounting Standards Update (“ASU”) of the Financial Accounting Standards Board (“FASB”) and in accordance with Article 10 of Regulation S-X. Accordingly, they do not include all of the information and note disclosures required by GAAP for complete financial statements. These statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2021 that has been filed with the SEC.

In the opinion of management, the accompanying unaudited condensed consolidated financial statements include all normal and recurring adjustments that are necessary for a fair presentation of results for the interim periods presented. The results of operations for any interim period may not be indicative of results for the full fiscal year or any other subsequent period. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements. Actual results may differ from these estimates.

There have been no changes in the Company’s significant accounting policies for the three and six 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 March 31, 2021 that has been filed with the SEC.

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements. Actual results may differ from these estimates.

Certain prior period amounts within the notes to the condensed consolidated financial statements have been reclassified to conform to the current period presentation.

COVID-19 Pandemic

The Company is subject to additional risks and uncertainties as a result of the ongoing novel coronavirus (“COVID-19”) pandemic. The ongoing COVID-19 pandemic has adversely impacted and is likely to further adversely impact the Company’s business and markets, including the Company’s workforce and the operations of its customers, suppliers, and business partners. While the COVID-19 (including new variants of COVID-19) pandemic remains fluid and continues to evolve differently across various geographies, the Company believes it is likely to continue to experience variable impacts on its business, including, for example: supply shortages, particularly of its product components; supply chain disruptions, which may limit its ability to manufacture or distribute its products.

The depth and extent to which the COVID-19 pandemic may directly or indirectly impact the Company’s business, results of operations, financial condition and individual markets is dependent upon various factors, including the spread of additional variants; the availability of vaccinations, personal protective equipment, intensive care unit (“ICU”) and operating room capacity, and medical staff; and government interventions to reduce the spread of the virus. During the second quarter of fiscal year 2022, the Company has experienced varying levels of recovery across its product lines and geographic locations from the challenges caused by the pandemic. Despite these improvements, the impact of COVID-19 on the Company’s patient utilization volumes is likely to vary widely by country, region, and type. In particular, Impella product revenue increased in the three and six months ended September 30, 2021 as a result of sales mix and higher patient utilization in the U.S., Germany and Japan as compared to the three and six months ended September 30, 2020, however, in the second quarter of fiscal year 2022, patient utilization of Impella heart pump devices was negatively impacted by an increase in COVID-19 hospitalizations and ongoing shortage of hospital workers that limited ICU capacity which contributed to some deferral of elective procedures. When COVID-19 infection rates spike in a particular region, the Company’s patient utilization volumes have generally been negatively impacted as hospitals face capacity limitations, staffing shortages and some in-patient treatments have been deferred. While the Company believes there may be a backlog of patients in need

8

of medical attention that requires the use of the Company’s products, it is difficult to predict when or if those patients may ultimately seek treatment, and therefore, the extent to which COVID-19 may impact patient utilization and, consequently, product revenue.

To ensure the health and safety of its global employees, the Company continues to offer onsite COVID-19 testing and vaccinations in order to maintain a safe working environment. The Company’s proactive testing and vaccination programs have reduced exposure with early detection and enabled its manufacturing facilities to operate at full capacity.  

The Company continues to closely monitor the impact of COVID-19 on all aspects of its business and geographies, including any impact on the Company’s customers, employees, suppliers, vendors, business partners and distribution channels, as well as on procedures and the demand for its products by keeping apprised of local, regional, and global COVID-19 surges (including new variants of the virus). As of the date of issuance of these financial statements, the extent to which the COVID-19 pandemic may lead materially adversely affect the Company’s financial condition, liquidity or results of operations is uncertain.

Recently Adopted Accounting Pronouncements

In December 2019, the Financial Accounting Standards Board (“FASB”) issued ASU 2019-12, Simplifying the Accounting for Income Taxes (ASC 740). The ASU enhances and simplifies various aspects of the income tax accounting guidance in ASC 740, including requirements related to hybrid tax regimes, the tax basis step-up in goodwill obtained in a transaction that is not a business combination, separate financial statements of entities not subject to tax, the intra-period tax allocation exception to the incremental approach, ownership changes in investments, changes from a subsidiary to an equity method investment, interim-period accounting for enacted changes in tax law, and the year-to-date loss limitation in interim-period tax accounting. This guidance is effective for the Company for annual and interim periods beginning after December 31, 2020; however, early adoption is permitted. The Company adopted this standard as of April 1, 2021 on a prospective basis. The adoption did not have a material impact on the Company’s condensed consolidated financial statements.

In January 2020, the FASB issued ASU 2020-01, “Investments—Equity Securities (Topic 321), Investments—Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815),” an amendment clarifying the interaction between accounting standards related to equity securities, equity method investments, and certain derivative instruments. The guidance is effective for fiscal years beginning after December 15, 2020. The Company adopted this standard as of April 1, 2021 and the adoption did not have a material impact on the Company’s condensed consolidated financial statements.

Recently Issued Accounting Pronouncements Not Yet Effective

No other new accounting pronouncements, issued or effective, during the period had, or are expected to have, a material impact on the condensed consolidated financial statements.

Note 3. Acquisitions

Acquisition of preCARDIA, Inc.

The Company acquired 100% interest in preCARDIA , Inc. (“preCARDIA”) on May 28, 2021. preCARDIA is a developer of a proprietary catheter and controller that is expected to complement the Company’s product portfolio to expand options for patients with acute decompensated heart failure (“ADHF”). The preCARDIA system is uniquely designed to rapidly treat ADHF-related volume overload by effectively reducing cardiac filling pressures and promoting decongestion to improve overall cardiac and renal function. The Company determined that substantially all of the fair value was concentrated in the acquired in-process research and development asset in accordance with ASC 805 Business Combinations. As such, the acquisition was accounted for as an asset acquisition.

The Company acquired preCARDIA for a purchase price of $115.2 million, with a potential payout of $5 million payable based on achievement of a commercial milestone. The purchase price included cash consideration of $82.8 million for the remaining interest in preCARDIA, paid to the selling shareholders and for transaction costs associated with the acquisition and $32.4 million representing the Company’s previously owned minority interest in preCARDIA. The Company recognized a gain of $21.0 million related to its previously owned minority interest in preCARDIA within the condensed consolidated statement of operations for the six months ended September 30, 2021.  

In connection with the acquisition, the Company acquired net assets of $115.2 million, which included $115.5 million related to the fair value of the in-process research and development asset and $0.3 million for net liabilities assumed. Since the acquired technology platform is pre-commercial and has not reached technical feasibility, the cost of the in-process research and development asset was expensed, resulting in a charge of $115.5 million to the condensed consolidated statement of operations for the six months ended September 30, 2021.

Acquisition of Breethe, Inc.

The Company acquired Breethe, Inc. (“Breethe”), a Maryland corporation, on April 24, 2020. Breethe is engaged in research and development of a novel extracorporeal membrane oxygenation (“ECMO”) system that will complement and expand its product portfolio to more comprehensively serve the needs of patients whose lungs can no longer provide sufficient oxygenation, including patients suffering from cardiogenic shock, or respiratory failure, such as ARDS, H1N1, or COVID-19. The Company acquired Breethe for $55.0 million in cash, with additional potential payouts up to a maximum of $55.0 million payable based on the achievement of certain technical, regulatory and commercial milestones.

Purchase Price Allocation

The acquisition was accounted for as a business combination. The purchase price for the acquisition has been allocated to the assets acquired and liabilities assumed based on their estimated fair values and was finalized in the year ended March 31, 2021.

The acquisition-date fair value of the consideration transferred is as follows:

	Total Acquisition Date Fair Value (in thousands)
Cash and other considerations	$	57,850
Contingent consideration		13,300
Total consideration transferred	$	71,150

The following table summarizes the estimated fair values of the assets acquired and liabilities assumed on the date of acquisition (in thousands):

Acquired assets:
Cash and cash equivalents	$	3,404
Property and equipment		744
Goodwill		44,485
In-process research and development		27,000
Other assets acquired		895
Total assets acquired		76,528
Liabilities assumed:
Accounts payable and other liabilities		1,562
Deferred tax liabilities		3,816
Net assets acquired	$	71,150

Goodwill is calculated as the difference between the acquisition-date fair value of the consideration transferred and the fair values of the assets acquired and liabilities assumed. The goodwill is not expected to be deductible for income tax purposes.

Note 4. Net Income Per Share

Basic net income per share is computed by dividing net income by the weighted average number of common shares outstanding during the period. Diluted net income per share is computed by dividing net income by the weighted average number of dilutive common shares outstanding during the period. Diluted shares outstanding are calculated by adding to the weighted average shares outstanding any potential dilutive securities outstanding for the period. Potential dilutive securities include stock options, restricted stock units, performance-based stock awards and shares to be purchased under the Company’s employee stock purchase plan.

For purposes of the diluted net income per share calculation, potential dilutive securities are excluded from the calculation if their effect would be anti-dilutive.

The following tables illustrate the determination of basic and diluted net income per share for each period presented (in thousands, except per share data):

	For the Three Months Ended September 30,				For the Six Months Ended September 30,
		2021		2020		2021		2020
Net income	$	56,953	$	62,213	$	30,428	$	106,801

	For the Three Months Ended September 30,				For the Six Months Ended September 30,
		2021		2020		2021		2020
Net income	$	56,953		62,213		30,428		106,801
Weighted average shares – basic		45,437		45,104		45,374		45,057
Effect of dilutive securities		456		557		483		552
Weighted average shares – diluted		45,893		45,661		45,857		45,609
Net income per share – diluted	$	1.24	$	1.36	$	0.66	$	2.34

Share-based compensation awards of approximately 0.2 million and 0.1 million shares for the three months ended September 30, 2021 and 2020, respectively, and approximately 0.2 million and 0.2 million for the six months ended September 30, 2021 and 2020, respectively, were outstanding but were not included in the computation of diluted net income per share because the effect of including such shares would have been anti-dilutive or such shares are contingently issuable upon meeting performance criteria in the periods presented.

Note 5. Revenue Recognition 

Revenue is recognized when, or as, obligations under the terms of a contract are satisfied, which occurs when control of the promised products or services is transferred to customers.  Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring products or services to a customer.

Product revenue is generally recognized when the customer obtains control of the Company’s product, which occurs at a point in time, and may be upon shipment or upon delivery based on the contractual shipping terms of a contract.

Service revenue is generally recognized over time as the services are rendered to the customer based on the extent of progress towards completion of the performance obligation. The Company recognizes service revenue over the term of the service contract. Services are expected to be transferred to the customer throughout the term of the contract and the Company believes recognizing revenue ratably over the term of the contract best depicts the transfer of value to the customer. Revenue generated from preventative maintenance calls is recognized at a point in time when the services are provided to the customer.

Revenue from the sale of products and services is evidenced by either a contract with the customer or a valid purchase order and an invoice which includes all relevant terms of sale and shipment of product or service provided has been incurred. The Company performs a review of each specific customer’s credit worthiness and ability to pay prior to acceptance as a customer. Further, the Company performs periodic reviews of its customers’ creditworthiness prospectively.

If a contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. Contracts that contain multiple performance obligations require an allocation of the transaction price based on the estimated relative standalone selling prices of the promised products or services underlying each performance obligation. The Company determines standalone selling prices based on the price at which the performance obligation is sold separately.  

11

Disaggregation of Revenue

Revenue is disaggregated between product revenue and service and other revenue and by geography, which the Company believes best depicts how the nature, amount, timing, and uncertainty of revenues and cash flows are affected by economic factors. The Company generally sells its products and services through a direct sales force in the U.S. and Germany and through direct sales and distribution agreements in other international markets outside (e.g., Japan, Europe, Canada, Latin America, Asia-Pacific, Middle East).

The following table disaggregates the Company’s revenue by products and services:

	For the Three Months Ended September 30,				For the Six Months Ended September 30,
		2021		2020		2021		2020
	(in thousands)				(in thousands)
Product revenue	$	235,785	$	199,676	$	477,259	$	355,093

Total revenue	$	248,142	$	209,764	$	500,727	$	374,614

Variable Consideration

Returns Reserve

The Company estimates an allowance for future sales returns based on historical return experience, which requires judgment. 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 the related product revenue is recognized.  The Company estimates product return liabilities using the expected value method based on its historical sales information and other factors that it believes could significantly impact its expected returns, including product discontinuations, product recalls and expirations, of which it becomes aware. The Company’s cost of replacing defective products has not been material and is accounted for at the time of replacement. The Company’s returns reserve as of September 30, 2021 and March 31, 2021, was not material.

Rebates and Discounts  

The Company provides certain customers with rebates and discounts that are defined in the Company’s contract arrangements with customers and are recorded as a reduction of revenue in the period the related revenue is recognized, resulting in a reduction to revenue and the establishment of a liability, which are all included in accrued expenses in the accompanying consolidated balance sheet. Rebates normally result from performance-based offers that are primarily based on attaining contractually specified sales volumes as well as product usage.  Discounts are normally from early payment incentives. The Company estimates the amount of rebates and discounts based on an estimate of the third-party’s sales and the respective rebate or discount defined in the customer contractual arrangement. Revenue adjustments that relate to performance obligations satisfied in prior periods during the three and six months ended September 30, 2021 and 2020, were not material.

Contract Balances

Deferred Revenue

The Company’s deferred revenue balance was $24.1 million and $24.3 million as of September 30, 2021 and March 31, 2021 respectively. The deferred revenue balance is due to the timing of product shipment and completion of recognizing revenue when the customer obtains control of the product, and additional preventative maintenance service contracts and the subsequent recognition of

12

the contract ratably over the term of the service contract. The Company recognized $9.9 million and $21 million of revenue during the three and six months ended September 30, 2021, that was included in the deferred revenue balance as of March 31, 2021. The Company recognized $5.4 million and $14.6 million of revenue during the three and six months ended September 30, 2020,that was included in the deferred revenue balance as of March 31, 2020.

Derivative Instruments

In October 2019, the Company entered into an intercompany agreement in which it loaned 85.0 million Euro to Abiomed Europe GMBH, its German subsidiary.  In conjunction with this intercompany loan agreement, the Company entered into a cross-currency swap agreement to convert a notional amount of 85.0 million Euro equivalent to $93.5 million denominated intercompany loan into U.S. dollars. The objective of this cross-currency swap is to hedge the variability of cash flows related to the forecasted interest and principal payments on the Euro denominated fixed rate loan against changes in the exchange rate between the U.S. dollar and the Euro. Under the terms of this cross-currency swap contract, which has been designated as a cash flow hedge, the Company will make interest payments in Euro and receive interest in U.S. dollars. Upon the maturity of this contract, the Company will pay the principal amount of the loan in Euro and receive U.S. dollars from the counterparty. The cross-currency swap is carried on the consolidated balance sheet at fair value, and changes in the fair values are recorded as unrealized gains or losses in accumulated other comprehensive (loss) income.

The Company does not enter into derivative instruments for any purpose other than cash flow hedging.

The following table summarizes the terms of the cross-currency swap agreement as of September 30, 2021:

	Effective Date	Maturity	Fixed Rate	Aggregate Notional Amount (in thousands)
Pay EUR	October 15,	October 15,	2.75%		EUR 85,000
Receive U.S.$	2019	2024	4.64%		USD 93,457

The following table presents the fair value of the Company’s derivative instrument:

Derivatives designated as hedging instruments under ASC 815	Balance Sheet classification	September 30, 2021		March 31, 2021
Cross-currency swap	Other long-term liabilities	$	2,767	$	4,298

The Company has structured its cross-currency swap agreement to be 100% effective and, as a result, there was no net impact to earnings resulting from hedge ineffectiveness. Changes in the fair value of the cross-currency swap are designated as a hedging instrument that effectively offsets the variability of cash flows and are reported in accumulated other comprehensive (loss) income. These amounts subsequently are reclassified into the consolidated statements of operations in the same period in which the related hedged item affects earnings. The change in fair value of the cross-currency swap during the three and six months ended September 30, 2021 was mainly due to fluctuations in the Euro to the U.S. dollar exchange rates.

For the three and six months ended September 30, 2021, the Company recorded income related to the interest rate differential of the cross-currency swap of $0.4 million and $0.8 million, respectively in other income, net, within the condensed consolidated statements of operations. For both the three and six months ended September 30, 2020, the Company recorded income related to the interest rate differential of the cross-currency swap of $0.7 million in other income, net, within the condensed consolidated statements of operations.

Fair Value Hierarchy

Fair value is defined as the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Financial assets and liabilities carried at fair value are to be classified and disclosed in one of the following three categories:

Level 1 primarily consists of financial instruments whose values are based on quoted market prices such as exchange-traded instruments and listed equities.

Level 2 includes financial instruments that are valued using models or other valuation methodologies. These models are primarily industry-standard models that consider various assumptions, including time value, yield curve, volatility factors, prepayment speeds, default rates, loss severity, current market and contractual prices for the underlying financial instruments, as well as other relevant economic measures. Substantially all of these assumptions are observable in the marketplace, can be derived from observable data or are supported by observable levels at which transactions are executed in the marketplace.

Level 3 is comprised of unobservable inputs that are supported by little or no market activity. Financial assets are considered Level 3 when their fair values are determined using pricing models, discounted cash flows or similar techniques and at least one significant model assumption or input is unobservable.

The Company has determined that the estimated fair value of its money market funds and its investment in Shockwave Medical, a publicly traded medical device company, are reported as Level 1 financial assets as they are valued at quoted market prices in active markets. The investment in Shockwave Medical is classified within other assets in the condensed consolidated balance sheets.

The Company has determined that the estimated fair value of its repurchase agreements, U.S. Treasury mutual fund securities, government-backed securities, corporate debt securities and commercial paper and cross-currency swap agreement are reported as Level 2 financial assets and liabilities as they are based on model-driven valuations in which all significant inputs are observable, or can be derived from or corroborated by observable market data for substantially the full term of the asset or liability.

The Company evaluates transfers between fair value levels at the end of each reporting period. There were no transfers of assets or liabilities between fair value levels during the six months ended September 30, 2021.

Level 3 Assets and Liabilities

Other Investments

The Company periodically makes investments in medical device companies that focus on heart failure and heart pumps and other medical device technologies. The Company measures these investments at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for an identical or similar investment. The Company monitors any events or changes in circumstances that may have a significant effect on the fair value of investments, either due to impairment or based on observable price changes and makes any necessary adjustments.

15

The Company’s other investments balance is classified as a Level 3 asset and is not included in the fair value table above. The carrying value of the Company’s portfolio of other investments and the change in the balance for the six months ended September 30, 2021 are as follows:

Contingent Consideration

Contingent consideration represents potential milestones that the Company may pay as additional consideration related to the acquisition of ECP Entwicklungsgesellschaft mbH (“ECP”) in July 2014 and the acquisition of Breethe in April 2020. Changes in fair value of contingent consideration are reflected within research and development expenses in the Company’s condensed consolidated statements of operations. There is no assurance that any of the conditions for the milestone payments will be met.

The components of contingent consideration are as follows:

ECP

In July 2014, the Company acquired ECP and AIS GmbH Aachen Innovative Solutions (“AIS”) for $13.0 million in cash, with additional potential payouts totaling $15.0 million based on the achievement of CE Mark approval in the European Union and a revenue-based milestone related to the development of the future Impella ECP^TM expandable catheter pump technology. These potential milestone payments may be made, at the Company’s option, by a combination of cash or ABIOMED common stock. 

The Company uses a combination of an income approach, based on various revenue and cost assumptions and applies a probability to each outcome and a Monte-Carlo valuation model, both of which consider significant unobservable inputs. Probabilities are applied to the clinical and regulatory milestones, for each potential scenario and the resulting values are discounted using a rate that considers weighted average cost of capital as well as a specific risk premium associated with the riskiness of the earn out itself, the related projections, and the overall business. The revenue-based milestone is valued using a Monte-Carlo valuation model, which simulates estimated future revenues during the earn out-period using management’s best estimates.

Key unobservable inputs include the discount rate used to present value the projected revenues and cash flows (ranging from 1% to 2%), the probability of achieving the various technical, regulatory and commercial milestones (estimated to range from 15% be 74%) and projected revenues, which are based on the Company’s most recent internal operational budgets and long-range strategic plans.

Breethe

In April 2020, the Company acquired Breethe for $55.0 million in cash, with additional potential payouts up to a maximum of $55.0 million payable based on the achievement of certain technical, regulatory and commercial milestones.

16

The Company uses a combination of an income approach, based on various revenue and cost assumptions and applies a probability to each outcome and a Monte-Carlo valuation model, both of which consider significant unobservable inputs. For the regulatory milestones, probabilities are applied to each potential scenario and the resulting values are discounted using a rate that considers weighted average cost of capital as well as a specific risk premium associated with the riskiness of the earn out itself, the related projections, and the overall business. The commercial milestones are valued using a Monte-Carlo valuation model, which simulates estimated future revenues during the earn out-period using management’s best estimates.

Key unobservable inputs include the discount rates used to present value the projected revenues and cash flows (ranging from 1% to 2%), the probability of achieving the various technical, regulatory and commercial milestones (estimated to range from 15% to 75%) and projected revenues, which are based on the Company’s most recent internal operational budgets and long-range strategic plans.

Contingent consideration is classified as a Level 3 liability as the estimated fair value of the contingent consideration related to the acquisitions of ECP and Breethe require significant management judgment or estimation.

The following table summarizes the change in fair value, as determined by Level 3 inputs, of the contingent consideration for the six months ended September 30, 2021:

	(in thousands)
Balance, March 31, 2021	$	24,706
Change in fair value		108
Balance, September 30, 2021	$	24,814

The change in fair value of the contingent consideration was primarily due to estimates related to development timelines and the passage of time on the fair value measurement of milestones.

The significant unobservable inputs used in the fair value of the Company’s contingent consideration are the discount rate and forecasted financial information. Significant increases (decreases) in the discount rate would have resulted in a significantly lower (higher) fair value measurement. Significant increases (decreases) in the forecasted financial information would have resulted in a significantly higher (lower) fair value measurement. As of September 30, 2021 and March 31, 2021, the present value of expected payments related to the Company’s contingent consideration was $24.8 million and $24.7 million, respectively. The undiscounted value of the payments, assuming that all contingencies are met, would be $67.5 million as of September 30, 2021.

Note 9. Goodwill and Other Intangible Assets, net

Goodwill

The carrying amount of goodwill as of September 30, 2021 and March 31, 2021 was $78.2 million and $78.6 million, respectively, and has been recorded in connection with the Company’s acquisition of Impella Cardiosystems AG, in May 2005, ECP in July 2014 and Breethe in April 2020. The carrying value of goodwill and the change in the balance for the six months ended September 30, 2021 are as follows:

	(in thousands)
Balance, March 31, 2021	$	78,568

Total			$	42,712	$	(1,650	)	$	41,062		(750	)	$	42,150

The Company’s finite-lived intangible asset represents developed technology associated with the estimated fair value of the Breethe OXY-1 System. The estimated fair value of developed technology was determined using a probability-weighted income approach, which discounts expected future cash flows to present value. The projected cash flow estimates for the Breethe OXY-1 System were based on certain key assumptions, including estimates of future revenue and expenses, the stage of development of the technology at the acquisition date and the time and resources needed to complete development. During the year ended March 31, 2021, the Company reclassified the in-process research and development (“IPR&D”) asset to developed technology upon receiving FDA 510(k) clearance of the Breethe OXY-1 System and began amortizing the intangible asset on a straight-line basis over an estimated useful life of 15 years.

18

The Company’s IPR&D asset represents the estimated fair value of the Impella ECP^TM related to the acquisition of ECP and AIS, in July 2014. The estimated fair value of the IPR&D asset at the acquisition date was determined using a probability-weighted income approach, which discounts expected future cash flows to present value. The projected cash flow estimates for the future Impella ECP^TM expandable catheter pump were based on certain key assumptions, including estimates of future revenue and expenses, taking into account the stage of development of the technology at the acquisition date and the time and resources needed to complete development.

The Company evaluates the other intangible assets at least annually on October 31, as well as whenever events or changes in circumstances suggest that the carrying amount may not be recoverable. The Company has no accumulated impairment losses on other intangible assets. The change in the indefinite-lived intangible assets balance for the six months ended September 30, 2021, was related to the impact of foreign currency translation.

Options vested and expected to vest at end of period		612		$	175.86		5.90		95,180

Stock options generally vest and become exercisable annually over three years. The remaining unrecognized stock-based compensation expense for unvested stock option awards as of September 30, 2021, was approximately $10.9 million and the estimated weighted-average period over which this cost is expected to be recognized is 2.0 years.

The aggregate intrinsic value of stock options exercised was $42.8 million for the six months ended September 30, 2021. The total cash received as a result of employee stock option exercises for the six months ended September 30, 2021, was approximately $8.4 million.

The Company estimates the fair value of each stock option granted at the grant date using the Black-Scholes option valuation model.

The weighted average grant-date fair values and weighted average assumptions used in the calculation of fair value of options granted was as follows: 

	For the Three Months Ended September 30,						For the Six Months Ended September 30,
		2021			2020			2021			2020
Weighted average grant-date fair value	$	115.99		$	100.51		$	103.48		$	76.10

Restricted Stock Units

The following table summarizes activity of restricted stock units for the six months ended September 30, 2021:

				Weighted
				Average
	Number of			Grant Date
	Shares			Fair Value
	(in thousands)			(per share)
Restricted stock units at beginning of period		301		$	273.57
Granted		156			288.64
Vested		(103	)		304.20
Forfeited		(19	)		270.35
Restricted stock units at end of period		335		$	271.32

Restricted stock units generally vest annually over three years. The remaining unrecognized compensation expense for outstanding restricted stock units, including performance and market-based awards, as of September 30, 2021 was $70.6 million and the estimated weighted-average period over which this cost is expected to be recognized is 2.1 years.

The weighted average grant-date fair value for restricted stock units granted during the six months ended September 30, 2021 was $288.64. The total fair value of restricted stock units vested during the six months ended September 30, 2021 was $31.4 million.

Performance-Based Awards

The Company grants performance-based restricted stock units to certain executive officers and employees, which vest upon achievement of prescribed service milestones by the award recipients and the achievement of prescribed performance milestones by the Company. As of September 30, 2021, the Company recognized compensation expense based on the probable outcomes related to the prescribed performance targets on the outstanding awards.

Market-Based Awards

The Company grants market-based restricted stock units to certain executive officers and employees. These restricted stock units vest upon achievement of prescribed service-based milestones, relative TSR goals by the Company and the achievement of prescribed performance milestones, as defined in the respective agreements.

The relative total shareholder return (“TSR”) is based on the Company’s common stock in relation to the TSR of twenty peer companies over a defined period, based on a comparison of average closing stock prices during the 20 trading days prior to the first day of the performance period, reinstated dividends during each performance period and the average closing stock prices during the final 20 trading days of each performance period. The actual number of market-based restricted stock units that may be earned can range from 0% to 200% of the target number of shares. The payout percentage may be further adjusted based on the Company’s performance relative to the constituents of the S&P 500 Index on the first day of the performance period that are still actively trading on the last day of each performance period, as defined in the respective agreements.

The Company used a Monte-Carlo simulation model to estimate the grant-date fair value of the market-based restricted stock units. The fair value related to these awards are recorded as compensation expense over the period from date of grant, based on the probable outcomes related to the prescribed performance targets on the outstanding awards, regardless of the actual TSR outcome reached.

The table below sets forth the assumptions used to value the awards and the estimated grant-date fair value:

	May 2021			May  2020
Risk-free interest rate		0.3	%		0.2	%
Expected volatility		44.8	%		35.5	%
Dividend yield		—			—
Remaining performance period (years)		2.8		1.9 - 2.9
Estimated fair value per share	$	292.40		$347.05 - $349.28
Target performance (number of shares)		25,172			30,881

Note 15. Income Taxes

The Company’s income tax provision was $10.3 million and $10.7 million for the three months ended September 30, 2021 and 2020, respectively. The Company’s income tax provision was $27.5 million and $27.2 million for the six months ended September 30, 2021 and 2020, respectively. The Company’s effective tax rate was 15.3% and 14.7% for the three months ended September 30, 2021 and 2020, respectively. The Company’s effective tax rate was 47.5% and 20.3% for the six months ended September 30, 2021 and 2020, respectively. The effective tax rate differs from the statutory federal income tax rate of 21% for the three months ended September 30, 2021 and 2020 primarily due to the recognition of excess tax benefits associated with stock-based awards of $6.2 million and $7.9 million as an income tax benefit for the three months ended September 30, 2021 and 2020, respectively. The effective tax rate differs from the statutory federal income tax rate of 21% for the six months ended September 30, 2021 and 2020 primarily due to a non-deductible charge for in-process research and development related to the preCARDIA acquisition offset by excess tax benefits related to share-based compensation.    The Company recognized excess tax benefits associated with stock-based awards of $9.8 million and $8.5 million for the six months ended September 30, 2021 and 2020, respectively.

The Company is subject to the examination of its income tax returns by the Internal Revenue Service (“IRS”) and other tax authorities. The outcome of these audits cannot be predicted with certainty. The Company’s most recent completed income tax audits were in the U.S. relating to fiscal year 2016 and in Germany, which covered fiscal years 2012 through 2015. These tax audits did not materially impact the financial statements. The Company is currently undergoing an income tax audit by the German tax authorities on Abiomed Europe GMBH and ECP for fiscal years 2016 through 2019. All other tax years remain subject to examination by the federal, state and foreign tax authorities.

Note 16. Commitments and Contingencies

From time to time, the Company is involved in legal and administrative proceedings and claims of various types. In some actions, the claimants seek damages, as well as other relief, which, if granted, would require significant expenditures. The Company records a liability in its consolidated financial statements for these matters when a loss is known or considered probable and the amount can be reasonably estimated. The Company reviews these estimates each accounting period as additional information is known and adjusts the loss provision when appropriate. If a matter is both probable to result in liability and the amount of loss can be reasonably estimated, the Company estimates and discloses the possible loss or range of loss. If the loss is not probable or cannot be reasonably estimated, a liability is not recorded in its consolidated financial statements.

Maquet Matters

In December 2015, the Company received a letter from Maquet Cardiovascular LLC (“Maquet”), a subsidiary of Getinge AB, asserting that the Company’s Impella® devices infringe certain claims with guidewire, lumen, rotor, purge and sensor features, which were in two Maquet patents and one pending patent application (which has since issued as a third patent) in the U.S. and elsewhere, and attaching a draft litigation complaint.  The letter encouraged the Company to take a license from Maquet. In May 2016, the Company filed suit in U.S. District Court for the District of Massachusetts (“D. Mass.” or “the Court”) against Maquet, seeking a declaratory judgment that the Company’s Impella devices do not infringe Maquet’s cited patent rights.  

In August 2016, Maquet sent a letter to the Company identifying four new Maquet U.S. continuation patent filings with claims that Maquet alleges are infringed by the Company’s Impella devices. The four U.S. continuation applications have been issued as patents of Maquet but expired on September 1, 2020.

In September 2016, Maquet filed a response to the Company’s suit in D. Mass., including various counterclaims alleging that the Company’s Impella 2.5®, Impella CP®, Impella 5.0®, and Impella RP® heart pumps infringe certain claims of the three original issued U.S. patents (“2016 Action”). In July 2017, the Court granted a motion to add three of the four additional continuation patents to the 2016 Action.  In April 2018, the Court conducted a Markman hearing on claim interpretation. On September 7, 2018, the judge issued a Memorandum and Order on Claim Construction, where he interpreted the disputed claim terms in the case.  Maquet then filed a motion for reconsideration of the Court’s construction of one of the disputed claim terms. The motion was denied on May 22, 2019. As a result of the Court’s denial, only one of the six originally asserted patents is in dispute. The Company filed a motion for summary judgement (the “MSJ”) for the remaining patent on September 18, 2019 (non-infringement) and April 13, 2020 (invalidity). The parties argued the MSJ for non-infringement on November 19, 2019 and the MSJ for invalidity on August 20, 2020.  

On September 30, 2021, the Court granted the Company’s MSJ for non-infringement of the asserted claims in the remaining patent which expired on September 1, 2020.   On October 20, 2021, Maquet filed a motion for reconsideration of the Order in favor of the Company. The Company intends to file a response to Maquet’s motion in due time.  Because the Court has not yet issued a final judgement, the case is not yet appealable to the Federal Circuit.    

In November 2017, Maquet filed a second action in D. Mass (the “2017 Action”) alleging that the Company’s Impella 2.5®, Impella CP®, and Impella 5.0® heart pumps infringe certain claims of the fourth additional U.S. continuation patent mentioned above (the seventh patent overall). Discovery in the 2017 Action is ongoing.

24

In a series of letters during January and February 2019, Maquet informed the Company of seven new patent applications filed from the patents in the 2016 Action and 2017 Action with claims Maquet alleges would be infringed by the Impella® products if the new applications were to issue as patents. One of the newly issued patents has been added to the 2017 Action. A Markman hearing for the newly-added patent was held on November 18, 2019.  A Markman order has not been issued yet. The asserted patent in this case expired on September 1, 2020. Discovery remains ongoing.

In the 2016 Action and 2017 Action, Maquet seeks injunctive relief and monetary damages in the form of a reasonable royalty, with three times the amount for alleged willful infringement. In its responses to the Company’s counterclaims, Maquet admits that its current commercially available products do not embody the claims of the asserted patents.

The Company is unable to estimate the potential liability with respect to the legal matters noted above. There are numerous factors that make it difficult to meaningfully estimate possible loss or range of loss at this stage of the legal proceedings, including the significant number of legal and factual issues still to be resolved in the Maquet patent disputes.

Thoratec Matters

Thoratec Corporation (“Thoratec”), a subsidiary of Abbott Laboratories (“Abbott”), has challenged a number of Company-owned patents in Europe in connection with the launch of Thoratec’s HeartMate PHP™ medical device (“PHP”) in Europe and the Company has counterclaimed for infringement in the District Court, or the Court of 1st Instance, in Düsseldorf. The litigation was stayed pending the Federal Court of Justice, the Court of 3rd and Last Instance in Germany for patent infringement cases,  ruling on the validity and scope of the litigated patents. In September 2019, the Federal Court of Justice in Germany upheld the Company’s patents that are the subject of the patent infringement action for the sales and marketing of Thoratec’s PHP pump in Germany. Subsequently, the Court of 1st Instance in Düsseldorf lifted the stay, re-opened the litigation proceedings, and ruled in favor of the Company.  The Court of 1st Instance acknowledged that Thoratec’s PHP product infringes two of the Company’s patents related to the key features of Impella® intravascular pump and future expandable heart pump, known as Impella ECP®.  Abbott appealed and the oral hearing was held on August 26, 2021.  

On September 23, 2021, the Appellate Court (the “Court of 2nd Instance”) in Düsseldorf upheld the ruling by the Court of 1st Instance in both cases and did not allow an appeal to the Federal Court of Justice.  Thoratec has until the end of October 2021 to appeal the Court of 2nd Instance’s order denying appeal in both cases to the Federal Court of Justice.   If Thoratec forgoes the appeal or the case is not heard by Federal Court of Justice, then the verdict will be deemed final and enforceable. The judgement will remain provisionally enforceable until the final resolution, which means that the Company is able to seek a court ordered injunction preventing the sale and marketing by Thoratec of PHP, should Thoratec attempt to launch HeartMate PHP in Germany.

These actions relate solely to Thoratec’s ability to manufacture and sell its PHP product in Europe and have no impact on the Company's ability to manufacture or sell its Impella® line of medical devices.  The actions do not expose the Company to liability risk, except under local German law, which requires a losing party in a proceeding to pay a portion of the other party’s legal fees.

Securities Class Action Litigation

On or about August 6, 2019, the Company received a securities class action complaint filed on behalf of a single shareholder in the U.S. District Court for the Southern District of New York (“SDNY”), on behalf of himself and persons or entities that purchased or acquired the Company’s securities between January 31, 2019 through July 31, 2019. On October 7, 2019, a similar purported class action complaint was filed by a different shareholder on behalf of himself and persons or entities that purchased or acquired the Company’s securities between November 1, 2018 and July 31, 2019. Also, on October 7, 2019, four shareholders filed applications to be appointed lead plaintiff and for their counsel to be appointed lead counsel for the class. Two of those shareholders also filed motions to consolidate the two cases and two of the shareholders have withdrawn their applications to be lead plaintiff.

The complaints alleged that the Company violated Sections 10(b) and 20(a) of and Rule 10b-5 under the Exchange Act, in connection with allegedly misleading disclosures made by the Company regarding its financial condition and results of operations.

On June 29, 2020, SDNY issued an order consolidating the two cases and appointed Local 705 International Brotherhood of Teamsters Pension Fund as the lead plaintiff and Labaton Sucharow LLP as lead counsel.  On September 17, 2020, the lead plaintiff filed an amended complaint in which it proposed a new class period of May 3, 2018 to July 31, 2019. As prescribed by a scheduling order, the Company filed a motion to dismiss on November 16, 2020. On September 21, 2021, SDNY granted the Company’s motion, dismissed the amended complaint, and gave the lead plaintiff leave to move to amend the complaint by October 12, 2021. On October 12, 2021, the Company and the lead plaintiff entered into a stipulation to voluntarily dismiss the securities class action and SDNY ordered dismissal of the case with prejudice on the same day. Under the terms of the stipulation, the lead plaintiff has agreed not to move for leave to amend the complaint and not to appeal the dismissal of the action.  

Shareholder Derivative Litigation

25

On November 6 and 7, 2019, two shareholders filed derivative actions in SDNY that were subsequently consolidated.  On November 8, 2019, another shareholder filed a derivative action in Massachusetts Suffolk County Superior Court.  On January 7, 2020, another shareholder derivative action was filed in the U.S. District Court for the District of Delaware.  The complaints in these actions rely on many of the same allegations as in the securities class actions, and assert that, between November 1, 2018 and July 31, 2019, the directors of the Company made or allowed to be made misleading public statements regarding the Company’s growth, ultimately harming the Company.  

The Company has agreed with the plaintiffs in all three actions to stay the cases pending resolution of a motion to dismiss in the securities class actions. As a result of the stay, the Delaware action has been administratively closed.

Litigation Demand

On March 3, 2020, a shareholder sent a letter to the Board of Directors asserting that the directors of the Company made or allowed to be made misleading public statements regarding the Company’s growth. The letter relies on many of the same allegations as the securities class actions and derivative actions, and demands that the Board (i) undertake an independent investigation of the directors, (ii) bring suit against the directors on behalf of the Company, and (iii) take a number of additional affirmative actions to redress the purported wrongs. On March 30, 2020, the Company, after discussions with the Board of Directors, sent a written response to the shareholder’s counsel which they responded to on June 1, 2020.  The Company then sent a further response to the shareholder’s counsel on June 15, 2020, affirming the decision to defer consideration of the litigation demand pending further developments in the securities class action suit. Following the filing of the amended complaint in the securities class action, described above, the same shareholder renewed their demand on September 29, 2020.  The Company responded on October 9, 2020 and once again affirmed that it will defer consideration of the demand pending further substantive developments in the securities class action suit.

On November 5, 2020, a second shareholder sent a letter to the Board of Directors that made essentially the same demands as the September 29, 2020 letter from the first shareholder.  The Company responded on November 23, 2020, noting that it will defer consideration of the demand pending further substantive developments in the securities class action suit.  

The Company is unable to estimate the potential liability with respect to the various legal matters noted above. There are numerous factors that make it difficult to estimate reasonably possible loss or range of loss at this stage of the legal proceedings, including the significant number of legal and factual issues still to be resolved in the shareholder derivative litigations.

Note 17. Segment and Enterprise Wide Disclosures

The Company operates in one business segment: the research, development and sale of medical devices to assist or replace the pumping function of the failing heart. The Company’s chief operating decision maker (determined to be the Chief Executive Officer) does not manage any part of the Company separately, and the allocation of resources and assessment of performance are based on the Company’s consolidated operating results. Rest of world sales (meaning sales outside the U.S., primarily in Europe and Japan) accounted for 19% and 18% of total revenue for each of the three months ended September 30, 2021 and 2020, respectively. Rest of world sales (meaning sales outside the U.S., primarily in Europe and Japan) accounted for 19% and 18% of total revenue for each of the six months ended September 30, 2021 and 2020, respectively. The Company’s long-lived assets are located in the U.S., except for $56.9 million and $56.4 million at September 30, 2021 and March 31, 2021, respectively, which are located primarily in Germany.

Overview

We are a leading provider of medical devices that provide circulatory support and oxygenation. Our products are designed to enable the heart to rest by improving blood flow and/or provide sufficient oxygenation to those in respiratory failure. We develop, manufacture and market proprietary products that are designed to enable the heart to rest, heal and recover by improving blood flow to the coronary arteries and end-organs and/or temporarily assisting the pumping function of the heart. Our products are used in the cardiac catheterization lab, or cath lab, by interventional cardiologists, the electrophysiology lab, the hybrid lab and in the heart surgery suite by cardiac surgeons. A physician may use our devices for patients who are in need of hemodynamic support

27

prophylactically, urgently or emergently before, during or after angioplasty or heart surgery procedures. We believe that heart recovery is the optimal clinical outcome for a patient experiencing heart failure because it enhances the potential for the patient to go home with their own heart, facilitating the restoration of quality of life. In addition, we believe that, for the care of such patients, heart recovery is often the most cost-effective solution for the healthcare system.

Our strategic focus and the driver of our revenue growth is the market penetration of our family of Impella® heart pumps. The Impella device portfolio, which includes the Impella 2.5®, Impella CP®, Impella 5.0®, Impella LD®, Impella 5.5® and Impella RP® devices, has supported thousands of patients worldwide. We expect that most of our product and service revenue in the near future will be from our Impella devices. Our Impella 2.5, Impella CP, Impella 5.0, Impella LD, Impella 5.5 and Impella RP devices have U.S Food and Drug Administration or FDA and CE Mark approval which allows us to market these devices in the U.S. and European Union. We expect to continue to make additional pre-market approval, or PMA supplement submissions for our Impella portfolio of devices for additional indications. Our Impella 2.5, Impella CP and Impella 5.0 devices have regulatory approval from the Ministry of Health, Labor and Welfare, or MHLW, in Japan.

COVID-19 Pandemic

We are subject to additional risks and uncertainties as a result of the ongoing COVID-19 pandemic. The ongoing COVID-19 pandemic has adversely impacted and is likely to further adversely impact our business and markets, including our workforce and the operations of our customers, suppliers, and business partners. While the COVID-19 (including new variants of COVID-19) pandemic remains fluid and continues to evolve differently across various geographies, we believe we are likely to continue to experience variable impacts on its business, including, for example: supply shortages, particularly of our product components; supply chain disruptions, which may limit our ability to manufacture or distribute our products.

The depth and extent to which the COVID-19 pandemic may directly or indirectly impact our business, results of operations, financial condition and individual markets is dependent upon various factors, including the spread of additional variants; the availability of vaccinations, personal protective equipment, intensive care unit (“ICU”) and operating room capacity, and medical staff; and government interventions to reduce the spread of the virus. During the second quarter of fiscal year 2022, we experienced varying levels of recovery across our product lines and geographic locations from the challenges caused by the pandemic. Despite these improvements, the impact of COVID-19 on our patient utilization volumes is likely to vary widely by country, region, and type. In particular, our Impella product revenue increased in the three and six months ended September 30, 2021 as a result of sales mix and higher patient utilization in the U.S., Germany and Japan as compared to the three and six months ended September 30, 2020, however, in the second quarter of fiscal year 2022, patient utilization of Impella heart pump devices was negatively impacted by an increase in COVID-19 hospitalizations and ongoing shortage of hospital workers that limited ICU capacity which contributed to some deferral of elective procedures. When COVID-19 infection rates spike in a particular region, our patient utilization volumes have generally been negatively impacted as hospitals face capacity limitations, staffing shortages and some in-patient treatments have been deferred. While we believe there may be a backlog of patients in need of medical attention that requires the use of our products, it is difficult to predict when or if those patients may ultimately seek treatment, and therefore, the extent to which COVID-19 may impact patient utilization and, consequently, product revenue.

To ensure the health and safety of our global employees, we continue to offer onsite COVID-19 testing and vaccinations in order to maintain a safe working environment. Our proactive testing and vaccination programs have reduced exposure with early detection and enabled our manufacturing facilities to operate at full capacity.  

We continue to closely monitor the impact of COVID-19 on all aspects of our business and geographies, including any impact on our customers, employees, suppliers, vendors, business partners and distribution channels, as well as on procedures and the demand for our products by keeping apprised of local, regional, and global COVID-19 surges (including new variants of the virus). As of the date of issuance of these financial statements, the extent to which the COVID-19 pandemic may materially adversely affect our financial condition, liquidity or results of operations is uncertain.

Acquisition of preCARDIA

We acquired 100% interest in preCARDIA on May 28, 2021. preCARDIA is a developer of a proprietary catheter and controller that will complement Abiomed’s product portfolio to expand options for patients with acute decompensated heart failure (“ADHF”). The preCARDIA system is uniquely designed to rapidly treat ADHF-related volume overload by effectively reducing cardiac filling pressures and promoting decongestion to improve overall cardiac and renal function. We acquired preCARDIA for a purchase price of $115.2 million, with a potential payout of $5 million payable based on achievement of a commercial milestone.  The acquisition was accounted for as an asset acquisition as substantially all of the fair value of the acquisition related to the acquired in-process research and development asset.  Since the acquired technology platform is pre-commercial and has not reached technical feasibility, the cost of the in-process research and development asset was expensed, resulting in a charge of $115.5 million to the condensed consolidated statements of operations for the six months ended September 30 2021. In addition, we recognized a gain of $21.0 million related to our previously owned minority interest within the condensed consolidated statements of operations for the six months ended September 30 2021.

Our Existing Products

Impella 2.5®

The Impella 2.5 device is a percutaneous micro heart pump with an integrated motor and sensors. The device is designed primarily for use by interventional cardiologists to support patients in the cath lab who may require assistance to maintain circulation. The Impella 2.5 heart pump can be quickly inserted via the femoral artery to reach the left ventricle of the heart, where it is directly deployed to draw blood out of the ventricle and deliver it to the circulatory system. This function is intended to reduce ventricular work and provide blood flow to vital organs. The Impella 2.5 heart pump is introduced with normal interventional cardiology procedures and can pump up to 2.5 liters of blood per minute.

Our Impella 2.5 device has FDA, CE Mark and MHLW approvals which allows us to market these devices in the U.S., European Union and Japan, respectively. We expect to continue to make additional PMA supplement submissions for our Impella portfolio of devices for additional indications. Our Impella 2.5, Impella CP and Impella 5.0 devices have regulatory approval from the MHLW in Japan. The Impella 2.5 device also has Health Canada approval which allows us to market the device in Canada.

Impella CP®

The Impella CP device provides blood flow of approximately one liter more per minute than the Impella 2.5 device and is primarily used by either interventional cardiologists to support patients in the cath lab or by cardiac surgeons in the heart surgery suite.

Our Impella CP device has FDA, CE Mark, and MHLW approval which allows us to market this device in the U.S., European Union and Japan. We expect to continue to make additional PMA supplement submissions for our Impella portfolio of devices for additional indications of Impella CP in the U.S.

Impella 5.0® and Impella LD®

The Impella 5.0 and Impella LD devices are percutaneous micro heart pumps with integrated motors and sensors for use primarily in the heart surgery suite. These devices are designed to support patients who require higher levels of circulatory support as compared to the Impella 2.5 or Impella CP.

Our Impella 5.0 and Impella LD devices have FDA, CE Mark and MHLW approval which allows us to market these devices in the U.S., European Union and Japan. We expect to continue to make additional PMA supplement submissions for our Impella portfolio of devices for additional indications. Our Impella 5.0 device also has Heath Canada approval which allows us to market the device in Canada. We expect to discontinue production and sale of the Impella LD device in fiscal 2022.

Impella 5.5®

The Impella 5.5 device is designed to be a percutaneous micro heart pump with integrated motors and sensors. The Impella 5.5 delivers peak flows of greater than six liters per minute. The Impella 5.5 has a motor housing that is thinner and 45% shorter than the Impella 5.0 and it improves ease of pump insertion through the vasculature.

In September 2019, the Impella 5.5 device received a PMA from the FDA for safety and efficacy in the therapy of cardiogenic shock for up to 14 days in the U.S. The Impella 5.5 pump was introduced in the U.S. through a controlled rollout at hospitals with established heart recovery protocols beginning in fiscal year 2020. The Impella 5.5 device received CE Mark approval in Europe in April 2018 is being introduced in Europe through a similar controlled rollout. We have submitted an application to the PMDA for the Impella 5.5 device in Japan.

Impella RP®

Impella RP device is a percutaneous catheter-based axial flow pump that is designed to allow greater than four liters of blood flow per minute and is intended to provide the flow and pressure needed to compensate for right side heart failure. Our Impella RP device has FDA and CE Mark approval which allows us to market these devices in the U.S. and European Union. The Impella RP is the first percutaneous single access heart pump designed for right heart support to receive FDA approval. The Impella RP device is approved to provide support of the right heart during times of acute failure for certain patients who have received a left ventricle assist device or have suffered heart failure due to AMI, a failed heart transplant, or following open heart surgery. We expect to continue to make additional PMA supplement submissions for our Impella portfolio of devices for additional indications.

Impella SmartAssist®

The Impella SmartAssist platform includes optical sensor technology for improved pump positioning and the use of algorithms that enable improved native heart assessment during the weaning process.  The Impella SmartAssist platform is currently available for

29

our Impella CP, Impella 5.5 and Impella RP heart pumps. The Impella SmartAssist platform is also approved under CE Mark in the European Union and other countries that require a CE Mark approval.

Impella Connect®

Impella Connect is a cloud-based technology that enables secure, remote viewing of the Automated Impella Controller, or AIC, for physicians and hospital staff. We began a controlled roll-out of Impella Connect at certain hospital sites during fiscal year 2020 and have transitioned most of our customers in the U.S. and continue to introduce this technology to hospitals outside the U.S.

Abiomed Breethe OXY-1 System^TM

The Breethe OXY-1 System is a portable external respiratory assistance device that we acquired as part of our acquisition of Breethe, in April 2020 as part of our efforts to expand our product portfolio to support the needs of patients, such as those suffering from cardiogenic shock or respiratory failure, whose lungs can no longer provide sufficient oxygenation. The Breethe OXY-1 System takes venous blood from the patient, removes carbon dioxide and adds oxygen much like a human lung, and returns the oxygenated blood safely back to the patient. In October 2020, the Breethe OXY-1 System received a 510(k) clearance from the FDA for an all-in-one, compact cardiopulmonary bypass system. We will continue to conduct a controlled launch of the Breethe OXY-1 System at a limited number of hospitals in the U.S.

Our Product Pipeline

Impella ECP™

The Impella ECP device is designed for blood flow of greater than three liters per minute. It is intended to be delivered on a standard sized (9Fr) catheter and will include an expandable inflow in the left ventricle. The Impella ECP device has achieved initial FDA safety milestones, including completion of the first stage in its FDA early feasibility study (“EFS”). The prospective, multi-center, non-randomized EFS is designed to allow us, study investigators, and the FDA to make qualitative assessments about the safety and feasibility of Impella ECP use in high-risk percutaneous coronary intervention (“PCI”) patients. In fiscal year 2021, we received approval from the FDA to expand the EFS for the Impella ECP device and we continue to enroll patients in this study. In August 2021, we received Breakthrough Device designation by the FDA for the Impella ECP device, which is provided pursuant to the FDA’s Breakthrough Device Program, a program intended to help patients receive more timely access to certain medical technologies by providing a speedier development, assessment and review process for such technologies. Concurrently, we are finalizing the protocol of a single arm pivotal high-risk PCI study for the Impella ECP device as part of an investigational device exemption (“IDE”) submission with the FDA. The Impella ECP device is still in development and has not been approved for commercial use or sale.

Impella XR Sheath™

The Impella XR Sheath is a low-profile sheath that expands and recoils, allowing for small bore access and closure with certain Impella heart pumps. It inserts at 10 French (Fr) and the flexible, nitinol braids momentarily expand during insertion, then recoil, simplifying access for complex interventions. The Impella XR sheath is intended to produce less trauma at the arterial access site compared to large bore sheaths. In December 2020, the Impella XR Sheath for our Impella 2.5 device received a 510(k) clearance from the FDA. The Impella XR Sheath for our Impella CP device is still in development and has not been cleared for commercial use or sale.

Impella BTR™

The Impella BTR device is designed to be a percutaneous micro heart pump with integrated motors and sensors. The Impella BTR device is designed to be smaller, provide up to one year of hemodynamic support and is expected to allow for greater than five liters of blood flow per minute.  The Impella BTR device will also include a wearable driver designed for hospital discharge.  The Impella BTR pump is still in development and has not been approved for commercial use or sale. 

Critical Accounting Policies and Estimates

Other than the accounting policy changes discussed in “Note 2. Basis of Preparation and Summary of Significant Accounting Policies” to our condensed consolidated financial statements, which is incorporated herein by reference, there have been no significant changes in our critical accounting policies during the three and six months ended September 30, 2021, as compared to the critical accounting policies disclosed in Management’s Discussion and Analysis of Financial Condition and Results of Operations included in our Annual Report on Form 10-K for the fiscal year ended March 31, 2021.

Total revenue	$	248,142	$	209,764	$	500,727	$	374,614

Impella product revenue encompasses Impella 2.5, Impella CP, Impella 5.0, Impella LD, Impella 5.5, Impella RP and Impella AIC product sales and related accessories. Service and other revenue represents revenue earned on service maintenance contracts and preventative maintenance calls.

Total Revenue

Total revenue for the three months ended September 30, 2021 increased by $38.3 million, or 18%, to $248.1 million from $209.8 million for the three months ended September 30, 2020. Total revenue for the six months ended September 30, 2021 increased $126.1 million, or 34% to $500.7 million from $374.6 million for the six months ended September 30, 2020. The increase in total revenue from the three and six months ended September 30, 2020 to the three and six months ended September 30, 2021 was driven by both Impella product revenue and service and other revenue, as further described below.

31

Impella Product Revenue

Impella product revenue for the three months ended September 30, 2021 increased by $36.1 million, or 18%, to $235.8 million from $199.7 million for the three months ended September 30, 2020. Impella product revenue for the six months ended September 30, 2021 increased by $122.2 million, or 34%, to $477.3 million from $355.1 million for the six months ended September 30, 2020. Impella product revenue increased in the three and six months ended September 30, 2021 primarily related to sales mix and higher patient utilization in the U.S., Germany and Japan as compared to the three and six months ended September 30, 2020, as we are experiencing varying levels of recovery across our product lines and geographic locations due to the challenges caused by the COVID-19 pandemic. Despite these improvements, the impact of COVID-19 on our patient utilization volumes is likely to vary widely by country, region, and type. In the second quarter of fiscal year 2022, patient utilization of Impella heart pump devices was negatively impacted by an increase in COVID-19 hospitalizations and ongoing shortage of hospital workers that limited ICU capacity which contributed to some deferral of elective procedures. When COVID-19 infection rates spike in a particular region, our patient utilization volumes have generally been negatively impacted as hospitals face capacity limitations, staffing shortages and some in-patient treatments have been deferred. While we believe there may be a backlog of patients in need of medical attention that requires the use of our products, it is difficult to predict when or if those patients may ultimately seek treatment, and therefore, the extent to which COVID-19 may impact patient utilization and, consequently, product revenue.

Service and Other Revenue

Service and other revenue for the three months ended September 30, 2021 increased by $2.3 million, or 23%, to $12.4 million from $10.1 million for the three months ended September 30, 2020. Service and other revenue for the six months ended September 30, 2021 increased $4.0 million, or 21%, to $23.5 million from $19.5 million for the six months ended September 30, 2020.

The increase in total service and other revenue from the three and six months ended September 30, 2020 to the three and six months ended September 30, 2021 was primarily due to an increase in preventative maintenance service contracts. We have expanded the number of Impella AIC consoles at many of our existing higher volume customer sites and continue to sell additional consoles to new customer sites. We expect revenue growth for service revenue to be consistent with recent history as most of these higher volume customer sites in the U.S. have service contracts which typically have three-year terms.

Costs and Expenses

Cost of Revenue

Cost of revenue for the three months ended September 30, 2021 increased by $5.2 million, or 13%, to $43.9 million from $38.7 million for the three months ended September 30, 2020. Gross margin was 82.3% for the three months ended September 30, 2021 and 81.5% for the three months ended September 30, 2020.

Cost of revenue for the six months ended September 30, 2021 increased by $14.4 million, or 19%, to $89.1 million from $74.7 million for the six months ended September 30, 2020.  Gross margin was 82.2% for the six months ended September 30, 2021 and 80.1% for the six months ended September 30, 2020.

The increase in cost of product revenue from the three and six months ended September 30, 2020 to the three and six months ended September 30, 2021 was primarily due to increased production volume and investment in direct labor and overhead as we expanded our manufacturing capacity of our facilities in the U.S. and Germany. The increase in gross margin from the three and six months ended September 30, 2020 to the three and six months ended September 30, 2021 was primarily due to a higher production volume and sales mix primarily associated with our initial launch of Impella 5.5.

We expect that our ongoing investment in manufacturing capacity and the expansion of our Impella CP SmartAssist and Impella Connect platform may decrease gross margin slightly in the near future.

Research and Development Expenses

Research and development expenses for the three months ended September 30, 2021 increased by $10.5 million, or 34%, to $41.0 million from $30.5 million for three months ended September 30, 2020.

Research and development expense for the six months ended September 30, 2021 increased $21.8 million, or 38% to $78.7 million from $56.9 million for the six months ended September 30, 2020.

The increase in research and development expenses from the three and six months ended September 30, 2020 to the three and six months ended September 30, 2021 is primarily due to our increases in regulatory and quality hiring, ongoing product development initiatives relating to our existing and pipeline products, the development of the Impella ECP™, Breethe OXY-1 System™, Impella XR Sheath™, Impella BTR^TM and preCARDIA devices, the expansion of our engineering organization, continued investment in our

32

clinical trials, most notably the STEMI DTU and PROTECT IV studies, and our focus on clinical, technological and quality initiatives for our products.

We expect research and development expenses to continue to increase as we continue to increase engineering, product development and clinical spending related to our initiatives to improve our existing products and develop new technologies and conduct clinical studies. Research and development expenses can fluctuate with project timing.

Selling, General and Administrative Expenses

Selling, general and administrative expenses for the three months ended September 30, 2021 increased by $23.6 million, or 30%, to $102.8 million from $79.2 million for the three months ended September 30, 2020.

Selling, general, and administrative expenses for the six months ended September 30, 2021 increased $58.7 million, or 40%, to $206.3 million from $147.6 million for the six months ended September 30, 2020.

Selling, general and administrative expenses increased from the three and six months ended September 30, 2020 to the three and six months ended September 30, 2021 primarily due to increases in commercial hiring, marketing, clinical training and education initiatives and higher stock compensation expense.

We aim to continue to invest strategically in hiring and sales and marketing activities, with a particular focus on training and education to drive utilization of our Impella devices and recovery awareness for acute heart failure patients.

Operating Income

Operating income for the three months ended September 30, 2021 decreased by $0.9 million, to $60.4 million, compared to $61.3 million operating income for the three months ended September 30, 2020. Operating margin was 24.4% for the three months ended September 30, 2021 compared to 29.2% for the three months ended September 30, 2020. The decrease in operating income and margin was primarily due to strategic investments in clinical, engineering, commercial, training and marketing initiatives which increased operating expenses  as described above.

Operating income for the six months ended September 30, 2021 decreased by $84.2 million, to $11.2 million, compared to $95.4 million operating income for the six months ended September 30, 2020. Operating margin was 2.2% for the six months ended September 30, 2021 compared to 25.5% for the six months ended September 30, 2020. The decrease in operating income and margin was primarily due to the preCARDIA acquisition in May 2021. The acquisition was accounted for as an asset acquisition as substantially all of the fair value of the acquisition related to the acquired in-process research and development asset.  Since the acquired technology platform is pre-commercial and has not reached technical feasibility, the cost of the in-process research and development asset was expensed, resulting in a charge of $115.5 million to the condensed consolidated statements of operations for the six months ended September 30, 2021.

Other Income

Other income decreased by $4.8 million, to other income of $6.8 million for the three months ended September 30, 2021, compared to other income of $11.6 million for the three months ended September 30, 2020. The decrease was primarily due to the recognition of a $4.8 million gain from our investment in Shockwave Medical for the three months ended September 30, 2021, compared to a $10.8 million gain from our investment in Shockwave Medical for the three months ended September 30, 2020.

Other income, increased by $8.2 million, to other income of $46.8 million for the six months ended September 30, 2021, compared to other income of $38.6 million for the six months ended September 30, 2020. This increase was primarily due to a $21.0 million gain related to our previously owned minority interest in preCARDIA recognized upon the acquisition of preCARDIA in May 2021 and a $22.4 million gain from our investment in Shockwave Medical for the six months ended September 30, 2021, compared to a $34.7 million gain from our investment in Shockwave Medical for the six months ended September 30, 2020.

Income Tax Provision

Our income tax provision was $10.3 million and $10.7 million for the three months ended September 30, 2021 and 2020, respectively. Our effective tax rate was 15.3% and 14.7% for the three months ended September 30, 2021 and 2020, respectively. Our income tax provision was $27.5 million and $27.2 million for the six months ended September 30, 2021 and 2020, respectively. Our effective tax rate was 47.5% and 20.3% for the six months ended September 30, 2021 and 2020, respectively. The change in the effective tax rate for the six months ended September 30, 2021 is primarily due to a non-deductible charge for in-process research and development related to the preCARDIA acquisition offset by an increase in excess tax benefits related to share-based compensation.

33

Net Income

Net income for the three months ended September 30, 2021 was $57.0 million, or $1.25 per basic share and $1.24 diluted share, compared to net income of $62.2 million, or $1.38 per basic share and $1.36 per diluted share, for three months ended September 30, 2020.

Net income for the six months ended September 30, 2021, was $30.4 million, or $0.67 per basic share and $0.66 per diluted share, compared to net income of $106.8 million, or $2.37 per basic share and $2.34 per diluted share for the six months ended September 30, 2020.

Liquidity and Capital Resources

As of September 30, 2021, our total cash, cash equivalents and marketable securities totaled $861.5 million, an increase of $13.7 million compared to $847.8 million at March 31, 2021. The increase in our cash, cash equivalents and marketable securities during the six months ended September 30, 2021 was primarily due to changes in working capital.

Following is a summary of our cash flow activities:

	For the Six Months Ended September 30,
	2021			2020
Net cash provided by operating activities	$	115,931		$	108,968
Net cash used for investing activities		(108,395	)		(81,314	)
Net cash used for financing activities		(786	)		(14,711	)
Effect of exchange rate changes on cash		2,422			(3,043	)
Net increase in cash and cash equivalents	$	9,172		$	9,900

Cash Provided by Operating Activities

For the six months ended September 30, 2021, cash provided by operating activities consisted of net income of $30.4 million, plus non-cash items of $132.1 million offset by cash used in working capital of $46.6 million. Adjustments for non-cash items consisted primarily of $115.5 million for acquired preCARDIA in-process research and development, a $21.0 million gain related to our previously owned minority interest in preCARDIA recognized upon the acquisition of preCARDIA in May 2021, a $22.4 million change in fair value of our investments in Shockwave Medical and other private medical technology companies, $28.4 million of stock-based compensation expense, $13.9 million of depreciation and amortization expense, $8.2 million in deferred tax provision, $6.2 million in inventory and other write-downs, and $1.8 million in accretion on marketable securities. The change in cash from working capital included a $7.4 million decrease in accounts receivable due to timing of collections, a $21.9 million decrease in accounts payable, accrued expenses and other liabilities offset by a $20.3 increase in prepaid expenses and other assets and a $11.7 increase in inventory due to the mix of customer demand and production.

For the six months ended September 30, 2020, cash provided by operating activities consisted of net income of $106.8 million, adjustments for non-cash items of $19.7 million and cash used in working capital of $17.5 million. As discussed above, the change in net income was primarily due to modest increases in Impella revenue, lower selling, general and administrative expenses to reduced discretionary spending and hiring and gains from our investment in Shockwave Medical, partially offset by increases in research and development expenses due to product development and clinical initiatives relating to our existing and pipeline products and lower excess tax benefits. Adjustments for non-cash items consisted primarily of $20.9 million of stock-based compensation expense, $14.2 million in deferred tax provision, $11.1 million of depreciation and amortization expense, $3.1 million in inventory and other write-downs, and $0.5 million in accretion on marketable securities. The change in cash from working capital included a $4.8 million decrease in accounts receivable due to timing of collections, a $6.1 million decrease in inventory due to lower production volumes, a $32.1 million decrease in accounts payable and accrued expenses primarily due to payment of annual bonuses during the quarter ended September 30, 2020, and a $2.0 million increase in deferred revenue.

Cash Used for Investing Activities

For the six months ended September 30, 2021, net cash used for investing activities primarily consisted of $82.8 million for our acquisition of preCARDIA, $3.9 million for our investment in private medical technology companies, $7.3 million in purchases of marketable securities (net of sales), and $14.4 million for the purchase of property and equipment primarily related to continued expansion of manufacturing capacity, office space and research development facilities in Danvers and Aachen, Germany.

For the six months ended September 30, 2020, net cash used for investing activities primarily consisted of $74.4 million in purchases from the sale of marketable securities (net of maturities), $52.2 million in net cash for our acquisition of Breethe and $19.6 million used in the purchase of property and equipment primarily related to continued expansion of manufacturing capacity, office space and research development facilities in Danvers and Aachen, Germany. We also made an additional $3.1 million investment in a

34

private medical technology companies. These amounts were partially offset by $67.9 million in proceeds from the sale of Shockwave Medical securities.

Capital expenditures for fiscal year 2022 are estimated to range from $30 million to $40 million to support the long-term development of our business, including manufacturing capacity, building expansions in our Danvers and Aachen facilities and information systems development projects.

Cash Used for Financing Activities

For the six months ended September 30, 2021, net cash used for financing activities included $12.1 million in payments in lieu of issuance of common stock for payroll withholding taxes upon vesting of certain equity awards. These amounts were offset by $8.4 million in proceeds from the exercise of stock options and $3.0 million in proceeds from the issuance of stock under the employee stock purchase plan.

For the six months ended September 30, 2020, net cash used for financing activities included $11.3 million for the repurchase of our common stock and $10.9 million in payments in lieu of issuance of common stock for payroll withholding taxes upon vesting of certain equity awards. These amounts were offset by $5.6 million in proceeds from the exercise of stock options and $2.0 million in proceeds from the issuance of stock under the employee stock purchase plan.

Operating Capital Resources and Liquidity Requirements

Our sources of cash liquidity are primarily from existing cash and cash equivalents, marketable securities and cash flows from operations. On September 30, 2021, our total cash, cash equivalents, and short and long-term marketable securities totaled $861.5 million, an increase of $13.7 million compared to $847.8 million at March 31, 2021. Marketable securities at September 30, 2021 consisted of $619.7 million held in funds that invest in U.S. Treasury securities, government-backed securities, corporate debt securities and commercial paper. We generated operating cash flows of $115.9 million and $109.0 million for the six months ended September 30, 2021 and 2020, respectively. At September 30, 2021, we had no debt outstanding. We believe that our sources of liquidity are sufficient to fund the current requirements of working capital, capital expenditures, and other financial commitments for at least the next twelve months.

Our primary liquidity requirements are to fund the following: expansion of our commercial and operational infrastructures; expansion of our manufacturing capacity and office space; the procurement and production of inventory to meet customer demand for our Impella devices; funding of new product and business development initiatives, such as the recent acquisitions of preCARDIA and Breethe; ongoing commercial launch in Japan and expansion into potential new markets; increased clinical spending; legal expenses related to ongoing patent litigation and other legal matters; stock repurchases and payments in lieu of issuance of common stock for payroll withholding taxes upon vesting of certain equity awards and provide for general working capital needs. To date, we have primarily funded our operations through product sales and the sale of equity securities.

Our liquidity is influenced by our ability to sell our products in a competitive industry and our customers’ ability to pay for our products. Factors that may affect liquidity primarily include our ability to penetrate the market for our products, our ability to maintain or reduce the length of the selling cycle for our products, our capital expenditures, and our ability to collect cash from customers after our products are sold. We continue to review our short-term and long-term cash needs on a regular basis.

Off-Balance Sheet Arrangements

We had no off-balance sheet arrangements or guarantees of third-party obligations during the periods presented. An “off-balance sheet arrangement” generally entails a transaction, agreement or other contractual arrangement to which an entity unconsolidated with us, is a party under which we have any obligation arising under a guarantee contract, derivative instrument or variable interest or a retained or contingent interest in assets transferred to such entity or similar arrangement that serves as credit, liquidity or market risk support for such assets.

Contractual Obligations and Commercial Commitments 

We have various contractual obligations, which are recorded as liabilities in our condensed consolidated financial statements. Other items are not recognized as liabilities in our condensed consolidated financial statements but are required to be disclosed. There have been no material changes, outside of the ordinary course of business, to our contractual obligations as previously disclosed in our Annual Report on Form 10-K for the fiscal year ended March 31, 2021.

35

ITEM 3: QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

There have been no material changes to our quantitative and qualitative disclosures about market risk as compared to the quantitative and qualitative disclosures about market risk described in our Annual Report on Form 10-K for the fiscal year ended March 31, 2021.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our principal executive officer and principal financial officer, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) and Rule 15d-15(e) under the Exchange Act, as of September 30, 2021. Based on this evaluation, our principal executive officer and principal financial officer concluded that, as of September 30, 2021, these disclosure controls and procedures were effective to provide reasonable assurance that material information required to be disclosed by us, including our consolidated subsidiaries, in reports that we file or submit under the Exchange Act, is recorded, processed, summarized and reported, within the time periods specified in SEC rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

During the second quarter of our fiscal year ending March 31, 2022, there were no changes in our internal control over financial reporting (as defined in Rule 13a-15(f) and Rule 15d-15(f) under the Exchange Act), that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

36

PART II — OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

We are from time to time involved in various legal actions, the outcomes of which are not within our complete control and may not be known for prolonged periods of time. In some actions, the claimants seek damages, as well as other relief, which, if granted, would require significant expenditures and could impair our business and results of operations. Material legal proceedings are discussed in “Note 16. Commitments and Contingencies” to our condensed consolidated financial statements and such information is incorporated herein by reference.

ITEM 1A. RISK FACTORS

Investing in our common stock involves a high degree of risk. In addition to the other information set forth in this Report, you should carefully consider the factors discussed in Part I, “Item 1A. Risk Factors” in our Annual Report on Form 10-K for the year ended March 31, 2021, which could materially affect our business, financial condition or future results. The risk factors set forth below update, and should be read together with, the risk factors described in our Annual Report on Form 10-K for the fiscal year ended March 31, 2021.

Risks Related to Our Business, Industry and Operations

The various United States federal government orders and regulations directing employers to require their employees to be vaccinated could lead to labor disruptions, which could have a material adverse effect on our business and results of operations.

On September 9, 2021, President Biden issued an executive order obligating parties that contract with the federal government to require their employees to be fully vaccinated against COVID-19, with limited exceptions for certain accommodations. Additionally, on September 9, 2021, President Biden announced a plan directing the Department of Labor’s Occupational Safety and Health Administration (“OSHA”) to issue an emergency temporary standard requiring all private employers with 100 or more workers to mandate COVID-19 vaccination or produce a weekly test for all employees. As a company with more than 100 employees, we would thus be required to mandate COVID-19 vaccination of our workforce or require our unvaccinated employees to be tested weekly.

Given current information, it is not possible to predict with certainty the impacts the impending mandates would have on us. These mandates may result in increased costs, labor disruptions or employee attrition, which could be material as a substantial number of our employees are based in areas of the country where vaccination rates are below the national average. If we lose employees, it may be difficult in the current competitive labor market to find replacement employees, and this could have an adverse effect on future revenues and costs, which could be material. Additional uncertainty could be caused by competing and potentially conflicting laws and regulations, such as the recent executive order issued by the governor of Texas prohibiting vaccine mandates. Accordingly, the impending mandates when implemented could have a material adverse effect on our business and results of operations.

Basis of Preparation and Summary of Significant Accounting Policies

Note 2. Basis of Preparation and Summary of Significant Accounting Policies

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles, or GAAP, for interim financial reporting as found in the Accounting Standards Codification (“ASC”) and Accounting Standards Update (“ASU”) of the Financial Accounting Standards Board (“FASB”) and in accordance with Article 10 of Regulation S-X. Accordingly, they do not include all of the information and note disclosures required by GAAP for complete financial statements. These statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2021 that has been filed with the SEC.

In the opinion of management, the accompanying unaudited condensed consolidated financial statements include all normal and recurring adjustments that are necessary for a fair presentation of results for the interim periods presented. The results of operations for any interim period may not be indicative of results for the full fiscal year or any other subsequent period. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements. Actual results may differ from these estimates.

There have been no changes in the Company’s significant accounting policies for the three and six 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 March 31, 2021 that has been filed with the SEC.

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements. Actual results may differ from these estimates.

Certain prior period amounts within the notes to the condensed consolidated financial statements have been reclassified to conform to the current period presentation.

COVID-19 Pandemic

The Company is subject to additional risks and uncertainties as a result of the ongoing novel coronavirus (“COVID-19”) pandemic. The ongoing COVID-19 pandemic has adversely impacted and is likely to further adversely impact the Company’s business and markets, including the Company’s workforce and the operations of its customers, suppliers, and business partners. While the COVID-19 (including new variants of COVID-19) pandemic remains fluid and continues to evolve differently across various geographies, the Company believes it is likely to continue to experience variable impacts on its business, including, for example: supply shortages, particularly of its product components; supply chain disruptions, which may limit its ability to manufacture or distribute its products.

The depth and extent to which the COVID-19 pandemic may directly or indirectly impact the Company’s business, results of operations, financial condition and individual markets is dependent upon various factors, including the spread of additional variants; the availability of vaccinations, personal protective equipment, intensive care unit (“ICU”) and operating room capacity, and medical staff; and government interventions to reduce the spread of the virus. During the second quarter of fiscal year 2022, the Company has experienced varying levels of recovery across its product lines and geographic locations from the challenges caused by the pandemic. Despite these improvements, the impact of COVID-19 on the Company’s patient utilization volumes is likely to vary widely by country, region, and type. In particular, Impella product revenue increased in the three and six months ended September 30, 2021 as a result of sales mix and higher patient utilization in the U.S., Germany and Japan as compared to the three and six months ended September 30, 2020, however, in the second quarter of fiscal year 2022, patient utilization of Impella heart pump devices was negatively impacted by an increase in COVID-19 hospitalizations and ongoing shortage of hospital workers that limited ICU capacity which contributed to some deferral of elective procedures. When COVID-19 infection rates spike in a particular region, the Company’s patient utilization volumes have generally been negatively impacted as hospitals face capacity limitations, staffing shortages and some in-patient treatments have been deferred. While the Company believes there may be a backlog of patients in need

of medical attention that requires the use of the Company’s products, it is difficult to predict when or if those patients may ultimately seek treatment, and therefore, the extent to which COVID-19 may impact patient utilization and, consequently, product revenue.

To ensure the health and safety of its global employees, the Company continues to offer onsite COVID-19 testing and vaccinations in order to maintain a safe working environment. The Company’s proactive testing and vaccination programs have reduced exposure with early detection and enabled its manufacturing facilities to operate at full capacity.  

The Company continues to closely monitor the impact of COVID-19 on all aspects of its business and geographies, including any impact on the Company’s customers, employees, suppliers, vendors, business partners and distribution channels, as well as on procedures and the demand for its products by keeping apprised of local, regional, and global COVID-19 surges (including new variants of the virus). As of the date of issuance of these financial statements, the extent to which the COVID-19 pandemic may lead materially adversely affect the Company’s financial condition, liquidity or results of operations is uncertain.

Recently Adopted Accounting Pronouncements

In December 2019, the Financial Accounting Standards Board (“FASB”) issued ASU 2019-12, Simplifying the Accounting for Income Taxes (ASC 740). The ASU enhances and simplifies various aspects of the income tax accounting guidance in ASC 740, including requirements related to hybrid tax regimes, the tax basis step-up in goodwill obtained in a transaction that is not a business combination, separate financial statements of entities not subject to tax, the intra-period tax allocation exception to the incremental approach, ownership changes in investments, changes from a subsidiary to an equity method investment, interim-period accounting for enacted changes in tax law, and the year-to-date loss limitation in interim-period tax accounting. This guidance is effective for the Company for annual and interim periods beginning after December 31, 2020; however, early adoption is permitted. The Company adopted this standard as of April 1, 2021 on a prospective basis. The adoption did not have a material impact on the Company’s condensed consolidated financial statements.

In January 2020, the FASB issued ASU 2020-01, “Investments—Equity Securities (Topic 321), Investments—Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815),” an amendment clarifying the interaction between accounting standards related to equity securities, equity method investments, and certain derivative instruments. The guidance is effective for fiscal years beginning after December 15, 2020. The Company adopted this standard as of April 1, 2021 and the adoption did not have a material impact on the Company’s condensed consolidated financial statements.

Recently Issued Accounting Pronouncements Not Yet Effective

No other new accounting pronouncements, issued or effective, during the period had, or are expected to have, a material impact on the condensed consolidated financial statements.

Business Combinations [Abstract]

Acquisitions

Note 3. Acquisitions

Acquisition of preCARDIA, Inc.

The Company acquired 100% interest in preCARDIA , Inc. (“preCARDIA”) on May 28, 2021. preCARDIA is a developer of a proprietary catheter and controller that is expected to complement the Company’s product portfolio to expand options for patients with acute decompensated heart failure (“ADHF”). The preCARDIA system is uniquely designed to rapidly treat ADHF-related volume overload by effectively reducing cardiac filling pressures and promoting decongestion to improve overall cardiac and renal function. The Company determined that substantially all of the fair value was concentrated in the acquired in-process research and development asset in accordance with ASC 805 Business Combinations. As such, the acquisition was accounted for as an asset acquisition.

The Company acquired preCARDIA for a purchase price of $115.2 million, with a potential payout of $5 million payable based on achievement of a commercial milestone. The purchase price included cash consideration of $82.8 million for the remaining interest in preCARDIA, paid to the selling shareholders and for transaction costs associated with the acquisition and $32.4 million representing the Company’s previously owned minority interest in preCARDIA. The Company recognized a gain of $21.0 million related to its previously owned minority interest in preCARDIA within the condensed consolidated statement of operations for the six months ended September 30, 2021.  

In connection with the acquisition, the Company acquired net assets of $115.2 million, which included $115.5 million related to the fair value of the in-process research and development asset and $0.3 million for net liabilities assumed. Since the acquired technology platform is pre-commercial and has not reached technical feasibility, the cost of the in-process research and development asset was expensed, resulting in a charge of $115.5 million to the condensed consolidated statement of operations for the six months ended September 30, 2021.

Acquisition of Breethe, Inc.

The Company acquired Breethe, Inc. (“Breethe”), a Maryland corporation, on April 24, 2020. Breethe is engaged in research and development of a novel extracorporeal membrane oxygenation (“ECMO”) system that will complement and expand its product portfolio to more comprehensively serve the needs of patients whose lungs can no longer provide sufficient oxygenation, including patients suffering from cardiogenic shock, or respiratory failure, such as ARDS, H1N1, or COVID-19. The Company acquired Breethe for $55.0 million in cash, with additional potential payouts up to a maximum of $55.0 million payable based on the achievement of certain technical, regulatory and commercial milestones.

Purchase Price Allocation

The acquisition was accounted for as a business combination. The purchase price for the acquisition has been allocated to the assets acquired and liabilities assumed based on their estimated fair values and was finalized in the year ended March 31, 2021.

The acquisition-date fair value of the consideration transferred is as follows:

	Total Acquisition Date Fair Value (in thousands)
Cash and other considerations	$	57,850
Contingent consideration		13,300
Total consideration transferred	$	71,150

The following table summarizes the estimated fair values of the assets acquired and liabilities assumed on the date of acquisition (in thousands):

Acquired assets:
Cash and cash equivalents	$	3,404
Property and equipment		744
Goodwill		44,485
In-process research and development		27,000
Other assets acquired		895
Total assets acquired		76,528
Liabilities assumed:
Accounts payable and other liabilities		1,562
Deferred tax liabilities		3,816
Net assets acquired	$	71,150

Goodwill is calculated as the difference between the acquisition-date fair value of the consideration transferred and the fair values of the assets acquired and liabilities assumed. The goodwill is not expected to be deductible for income tax purposes.

Earnings Per Share [Abstract]

Net Income Per Share

Note 4. Net Income Per Share

Basic net income per share is computed by dividing net income by the weighted average number of common shares outstanding during the period. Diluted net income per share is computed by dividing net income by the weighted average number of dilutive common shares outstanding during the period. Diluted shares outstanding are calculated by adding to the weighted average shares outstanding any potential dilutive securities outstanding for the period. Potential dilutive securities include stock options, restricted stock units, performance-based stock awards and shares to be purchased under the Company’s employee stock purchase plan.

For purposes of the diluted net income per share calculation, potential dilutive securities are excluded from the calculation if their effect would be anti-dilutive.

The following tables illustrate the determination of basic and diluted net income per share for each period presented (in thousands, except per share data):

	For the Three Months Ended September 30,				For the Six Months Ended September 30,
		2021		2020		2021		2020
Net income	$	56,953	$	62,213	$	30,428	$	106,801

Net income per share – diluted	$	1.24	$	1.36	$	0.66	$	2.34

Share-based compensation awards of approximately 0.2 million and 0.1 million shares for the three months ended September 30, 2021 and 2020, respectively, and approximately 0.2 million and 0.2 million for the six months ended September 30, 2021 and 2020, respectively, were outstanding but were not included in the computation of diluted net income per share because the effect of including such shares would have been anti-dilutive or such shares are contingently issuable upon meeting performance criteria in the periods presented.

Revenue From Contract With Customer [Abstract]

Revenue Recognition

Note 5. Revenue Recognition 

Revenue is recognized when, or as, obligations under the terms of a contract are satisfied, which occurs when control of the promised products or services is transferred to customers.  Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring products or services to a customer.

Product revenue is generally recognized when the customer obtains control of the Company’s product, which occurs at a point in time, and may be upon shipment or upon delivery based on the contractual shipping terms of a contract.

Service revenue is generally recognized over time as the services are rendered to the customer based on the extent of progress towards completion of the performance obligation. The Company recognizes service revenue over the term of the service contract. Services are expected to be transferred to the customer throughout the term of the contract and the Company believes recognizing revenue ratably over the term of the contract best depicts the transfer of value to the customer. Revenue generated from preventative maintenance calls is recognized at a point in time when the services are provided to the customer.

Revenue from the sale of products and services is evidenced by either a contract with the customer or a valid purchase order and an invoice which includes all relevant terms of sale and shipment of product or service provided has been incurred. The Company performs a review of each specific customer’s credit worthiness and ability to pay prior to acceptance as a customer. Further, the Company performs periodic reviews of its customers’ creditworthiness prospectively.

If a contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. Contracts that contain multiple performance obligations require an allocation of the transaction price based on the estimated relative standalone selling prices of the promised products or services underlying each performance obligation. The Company determines standalone selling prices based on the price at which the performance obligation is sold separately.  

Disaggregation of Revenue

Revenue is disaggregated between product revenue and service and other revenue and by geography, which the Company believes best depicts how the nature, amount, timing, and uncertainty of revenues and cash flows are affected by economic factors. The Company generally sells its products and services through a direct sales force in the U.S. and Germany and through direct sales and distribution agreements in other international markets outside (e.g., Japan, Europe, Canada, Latin America, Asia-Pacific, Middle East).

The following table disaggregates the Company’s revenue by products and services:

	For the Three Months Ended September 30,				For the Six Months Ended September 30,
		2021		2020		2021		2020
	(in thousands)				(in thousands)

Variable Consideration

Returns Reserve

The Company estimates an allowance for future sales returns based on historical return experience, which requires judgment. 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 the related product revenue is recognized.  The Company estimates product return liabilities using the expected value method based on its historical sales information and other factors that it believes could significantly impact its expected returns, including product discontinuations, product recalls and expirations, of which it becomes aware. The Company’s cost of replacing defective products has not been material and is accounted for at the time of replacement. The Company’s returns reserve as of September 30, 2021 and March 31, 2021, was not material.

Rebates and Discounts  

The Company provides certain customers with rebates and discounts that are defined in the Company’s contract arrangements with customers and are recorded as a reduction of revenue in the period the related revenue is recognized, resulting in a reduction to revenue and the establishment of a liability, which are all included in accrued expenses in the accompanying consolidated balance sheet. Rebates normally result from performance-based offers that are primarily based on attaining contractually specified sales volumes as well as product usage.  Discounts are normally from early payment incentives. The Company estimates the amount of rebates and discounts based on an estimate of the third-party’s sales and the respective rebate or discount defined in the customer contractual arrangement. Revenue adjustments that relate to performance obligations satisfied in prior periods during the three and six months ended September 30, 2021 and 2020, were not material.

Contract Balances

Deferred Revenue

The Company’s deferred revenue balance was $24.1 million and $24.3 million as of September 30, 2021 and March 31, 2021 respectively. The deferred revenue balance is due to the timing of product shipment and completion of recognizing revenue when the customer obtains control of the product, and additional preventative maintenance service contracts and the subsequent recognition of

the contract ratably over the term of the service contract. The Company recognized $9.9 million and $21 million of revenue during the three and six months ended September 30, 2021, that was included in the deferred revenue balance as of March 31, 2021. The Company recognized $5.4 million and $14.6 million of revenue during the three and six months ended September 30, 2020,that was included in the deferred revenue balance as of March 31, 2020.

Gross realized gains and losses on sales of marketable securities were not material for the three and six months ended September 30, 2021 and 2020.

Derivative Instruments

In October 2019, the Company entered into an intercompany agreement in which it loaned 85.0 million Euro to Abiomed Europe GMBH, its German subsidiary.  In conjunction with this intercompany loan agreement, the Company entered into a cross-currency swap agreement to convert a notional amount of 85.0 million Euro equivalent to $93.5 million denominated intercompany loan into U.S. dollars. The objective of this cross-currency swap is to hedge the variability of cash flows related to the forecasted interest and principal payments on the Euro denominated fixed rate loan against changes in the exchange rate between the U.S. dollar and the Euro. Under the terms of this cross-currency swap contract, which has been designated as a cash flow hedge, the Company will make interest payments in Euro and receive interest in U.S. dollars. Upon the maturity of this contract, the Company will pay the principal amount of the loan in Euro and receive U.S. dollars from the counterparty. The cross-currency swap is carried on the consolidated balance sheet at fair value, and changes in the fair values are recorded as unrealized gains or losses in accumulated other comprehensive (loss) income.

The Company does not enter into derivative instruments for any purpose other than cash flow hedging.

The following table summarizes the terms of the cross-currency swap agreement as of September 30, 2021:

	Effective Date	Maturity	Fixed Rate	Aggregate Notional Amount (in thousands)
Pay EUR	October 15,	October 15,	2.75%		EUR 85,000
Receive U.S.$	2019	2024	4.64%		USD 93,457

The following table presents the fair value of the Company’s derivative instrument:

Derivatives designated as hedging instruments under ASC 815	Balance Sheet classification	September 30, 2021		March 31, 2021
Cross-currency swap	Other long-term liabilities	$	2,767	$	4,298

The Company has structured its cross-currency swap agreement to be 100% effective and, as a result, there was no net impact to earnings resulting from hedge ineffectiveness. Changes in the fair value of the cross-currency swap are designated as a hedging instrument that effectively offsets the variability of cash flows and are reported in accumulated other comprehensive (loss) income. These amounts subsequently are reclassified into the consolidated statements of operations in the same period in which the related hedged item affects earnings. The change in fair value of the cross-currency swap during the three and six months ended September 30, 2021 was mainly due to fluctuations in the Euro to the U.S. dollar exchange rates.

For the three and six months ended September 30, 2021, the Company recorded income related to the interest rate differential of the cross-currency swap of $0.4 million and $0.8 million, respectively in other income, net, within the condensed consolidated statements of operations. For both the three and six months ended September 30, 2020, the Company recorded income related to the interest rate differential of the cross-currency swap of $0.7 million in other income, net, within the condensed consolidated statements of operations.

Fair Value Hierarchy

Fair value is defined as the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Financial assets and liabilities carried at fair value are to be classified and disclosed in one of the following three categories:

Level 1 primarily consists of financial instruments whose values are based on quoted market prices such as exchange-traded instruments and listed equities.

Level 2 includes financial instruments that are valued using models or other valuation methodologies. These models are primarily industry-standard models that consider various assumptions, including time value, yield curve, volatility factors, prepayment speeds, default rates, loss severity, current market and contractual prices for the underlying financial instruments, as well as other relevant economic measures. Substantially all of these assumptions are observable in the marketplace, can be derived from observable data or are supported by observable levels at which transactions are executed in the marketplace.

Level 3 is comprised of unobservable inputs that are supported by little or no market activity. Financial assets are considered Level 3 when their fair values are determined using pricing models, discounted cash flows or similar techniques and at least one significant model assumption or input is unobservable.

The following tables present the Company’s assets and liabilities measured at fair value on a recurring basis:

	Level 1		Level 2		Level 3		Total

The Company has determined that the estimated fair value of its money market funds and its investment in Shockwave Medical, a publicly traded medical device company, are reported as Level 1 financial assets as they are valued at quoted market prices in active markets. The investment in Shockwave Medical is classified within other assets in the condensed consolidated balance sheets.

The Company has determined that the estimated fair value of its repurchase agreements, U.S. Treasury mutual fund securities, government-backed securities, corporate debt securities and commercial paper and cross-currency swap agreement are reported as Level 2 financial assets and liabilities as they are based on model-driven valuations in which all significant inputs are observable, or can be derived from or corroborated by observable market data for substantially the full term of the asset or liability.

The Company evaluates transfers between fair value levels at the end of each reporting period. There were no transfers of assets or liabilities between fair value levels during the six months ended September 30, 2021.

Level 3 Assets and Liabilities

Other Investments

The Company periodically makes investments in medical device companies that focus on heart failure and heart pumps and other medical device technologies. The Company measures these investments at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for an identical or similar investment. The Company monitors any events or changes in circumstances that may have a significant effect on the fair value of investments, either due to impairment or based on observable price changes and makes any necessary adjustments.

The Company’s other investments balance is classified as a Level 3 asset and is not included in the fair value table above. The carrying value of the Company’s portfolio of other investments and the change in the balance for the six months ended September 30, 2021 are as follows:

	(in thousands)
Balance, March 31, 2021	$	62,995
Additions		3,866
Change in investment upon acquisition (Note 3)		(11,443	)

Contingent Consideration

Contingent consideration represents potential milestones that the Company may pay as additional consideration related to the acquisition of ECP Entwicklungsgesellschaft mbH (“ECP”) in July 2014 and the acquisition of Breethe in April 2020. Changes in fair value of contingent consideration are reflected within research and development expenses in the Company’s condensed consolidated statements of operations. There is no assurance that any of the conditions for the milestone payments will be met.

The components of contingent consideration are as follows:

	September 30, 2021		March 31, 2021

Contingent consideration		22,314		24,706
Total contingent consideration	$	24,814	$	24,706

ECP

In July 2014, the Company acquired ECP and AIS GmbH Aachen Innovative Solutions (“AIS”) for $13.0 million in cash, with additional potential payouts totaling $15.0 million based on the achievement of CE Mark approval in the European Union and a revenue-based milestone related to the development of the future Impella ECP^TM expandable catheter pump technology. These potential milestone payments may be made, at the Company’s option, by a combination of cash or ABIOMED common stock. 

The Company uses a combination of an income approach, based on various revenue and cost assumptions and applies a probability to each outcome and a Monte-Carlo valuation model, both of which consider significant unobservable inputs. Probabilities are applied to the clinical and regulatory milestones, for each potential scenario and the resulting values are discounted using a rate that considers weighted average cost of capital as well as a specific risk premium associated with the riskiness of the earn out itself, the related projections, and the overall business. The revenue-based milestone is valued using a Monte-Carlo valuation model, which simulates estimated future revenues during the earn out-period using management’s best estimates.

Key unobservable inputs include the discount rate used to present value the projected revenues and cash flows (ranging from 1% to 2%), the probability of achieving the various technical, regulatory and commercial milestones (estimated to range from 15% be 74%) and projected revenues, which are based on the Company’s most recent internal operational budgets and long-range strategic plans.

Breethe

In April 2020, the Company acquired Breethe for $55.0 million in cash, with additional potential payouts up to a maximum of $55.0 million payable based on the achievement of certain technical, regulatory and commercial milestones.

The Company uses a combination of an income approach, based on various revenue and cost assumptions and applies a probability to each outcome and a Monte-Carlo valuation model, both of which consider significant unobservable inputs. For the regulatory milestones, probabilities are applied to each potential scenario and the resulting values are discounted using a rate that considers weighted average cost of capital as well as a specific risk premium associated with the riskiness of the earn out itself, the related projections, and the overall business. The commercial milestones are valued using a Monte-Carlo valuation model, which simulates estimated future revenues during the earn out-period using management’s best estimates.

Key unobservable inputs include the discount rates used to present value the projected revenues and cash flows (ranging from 1% to 2%), the probability of achieving the various technical, regulatory and commercial milestones (estimated to range from 15% to 75%) and projected revenues, which are based on the Company’s most recent internal operational budgets and long-range strategic plans.

Contingent consideration is classified as a Level 3 liability as the estimated fair value of the contingent consideration related to the acquisitions of ECP and Breethe require significant management judgment or estimation.

The following table summarizes the change in fair value, as determined by Level 3 inputs, of the contingent consideration for the six months ended September 30, 2021:

	(in thousands)
Balance, March 31, 2021	$	24,706
Change in fair value		108
Balance, September 30, 2021	$	24,814

The change in fair value of the contingent consideration was primarily due to estimates related to development timelines and the passage of time on the fair value measurement of milestones.

The significant unobservable inputs used in the fair value of the Company’s contingent consideration are the discount rate and forecasted financial information. Significant increases (decreases) in the discount rate would have resulted in a significantly lower (higher) fair value measurement. Significant increases (decreases) in the forecasted financial information would have resulted in a significantly higher (lower) fair value measurement. As of September 30, 2021 and March 31, 2021, the present value of expected payments related to the Company’s contingent consideration was $24.8 million and $24.7 million, respectively. The undiscounted value of the payments, assuming that all contingencies are met, would be $67.5 million as of September 30, 2021.

The carrying amount of goodwill as of September 30, 2021 and March 31, 2021 was $78.2 million and $78.6 million, respectively, and has been recorded in connection with the Company’s acquisition of Impella Cardiosystems AG, in May 2005, ECP in July 2014 and Breethe in April 2020. The carrying value of goodwill and the change in the balance for the six months ended September 30, 2021 are as follows:

Total			$	42,712	$	(1,650	)	$	41,062		(750	)	$	42,150

The Company’s finite-lived intangible asset represents developed technology associated with the estimated fair value of the Breethe OXY-1 System. The estimated fair value of developed technology was determined using a probability-weighted income approach, which discounts expected future cash flows to present value. The projected cash flow estimates for the Breethe OXY-1 System were based on certain key assumptions, including estimates of future revenue and expenses, the stage of development of the technology at the acquisition date and the time and resources needed to complete development. During the year ended March 31, 2021, the Company reclassified the in-process research and development (“IPR&D”) asset to developed technology upon receiving FDA 510(k) clearance of the Breethe OXY-1 System and began amortizing the intangible asset on a straight-line basis over an estimated useful life of 15 years.

The Company’s IPR&D asset represents the estimated fair value of the Impella ECP^TM related to the acquisition of ECP and AIS, in July 2014. The estimated fair value of the IPR&D asset at the acquisition date was determined using a probability-weighted income approach, which discounts expected future cash flows to present value. The projected cash flow estimates for the future Impella ECP^TM expandable catheter pump were based on certain key assumptions, including estimates of future revenue and expenses, taking into account the stage of development of the technology at the acquisition date and the time and resources needed to complete development.

The Company evaluates the other intangible assets at least annually on October 31, as well as whenever events or changes in circumstances suggest that the carrying amount may not be recoverable. The Company has no accumulated impairment losses on other intangible assets. The change in the indefinite-lived intangible assets balance for the six months ended September 30, 2021, was related to the impact of foreign currency translation.

Stock options generally vest and become exercisable annually over three years. The remaining unrecognized stock-based compensation expense for unvested stock option awards as of September 30, 2021, was approximately $10.9 million and the estimated weighted-average period over which this cost is expected to be recognized is 2.0 years.

The aggregate intrinsic value of stock options exercised was $42.8 million for the six months ended September 30, 2021. The total cash received as a result of employee stock option exercises for the six months ended September 30, 2021, was approximately $8.4 million.

The Company estimates the fair value of each stock option granted at the grant date using the Black-Scholes option valuation model.

The weighted average grant-date fair values and weighted average assumptions used in the calculation of fair value of options granted was as follows: 

	For the Three Months Ended September 30,						For the Six Months Ended September 30,
		2021			2020			2021			2020

Forfeited		(19	)		270.35
Restricted stock units at end of period		335		$	271.32

Restricted stock units generally vest annually over three years. The remaining unrecognized compensation expense for outstanding restricted stock units, including performance and market-based awards, as of September 30, 2021 was $70.6 million and the estimated weighted-average period over which this cost is expected to be recognized is 2.1 years.

The weighted average grant-date fair value for restricted stock units granted during the six months ended September 30, 2021 was $288.64. The total fair value of restricted stock units vested during the six months ended September 30, 2021 was $31.4 million.

Performance-Based Awards

The Company grants performance-based restricted stock units to certain executive officers and employees, which vest upon achievement of prescribed service milestones by the award recipients and the achievement of prescribed performance milestones by the Company. As of September 30, 2021, the Company recognized compensation expense based on the probable outcomes related to the prescribed performance targets on the outstanding awards.

Market-Based Awards

The Company grants market-based restricted stock units to certain executive officers and employees. These restricted stock units vest upon achievement of prescribed service-based milestones, relative TSR goals by the Company and the achievement of prescribed performance milestones, as defined in the respective agreements.

The relative total shareholder return (“TSR”) is based on the Company’s common stock in relation to the TSR of twenty peer companies over a defined period, based on a comparison of average closing stock prices during the 20 trading days prior to the first day of the performance period, reinstated dividends during each performance period and the average closing stock prices during the final 20 trading days of each performance period. The actual number of market-based restricted stock units that may be earned can range from 0% to 200% of the target number of shares. The payout percentage may be further adjusted based on the Company’s performance relative to the constituents of the S&P 500 Index on the first day of the performance period that are still actively trading on the last day of each performance period, as defined in the respective agreements.

The Company used a Monte-Carlo simulation model to estimate the grant-date fair value of the market-based restricted stock units. The fair value related to these awards are recorded as compensation expense over the period from date of grant, based on the probable outcomes related to the prescribed performance targets on the outstanding awards, regardless of the actual TSR outcome reached.

The table below sets forth the assumptions used to value the awards and the estimated grant-date fair value:

	May 2021			May  2020
Risk-free interest rate		0.3	%		0.2	%

Income Taxes

Note 15. Income Taxes

The Company’s income tax provision was $10.3 million and $10.7 million for the three months ended September 30, 2021 and 2020, respectively. The Company’s income tax provision was $27.5 million and $27.2 million for the six months ended September 30, 2021 and 2020, respectively. The Company’s effective tax rate was 15.3% and 14.7% for the three months ended September 30, 2021 and 2020, respectively. The Company’s effective tax rate was 47.5% and 20.3% for the six months ended September 30, 2021 and 2020, respectively. The effective tax rate differs from the statutory federal income tax rate of 21% for the three months ended September 30, 2021 and 2020 primarily due to the recognition of excess tax benefits associated with stock-based awards of $6.2 million and $7.9 million as an income tax benefit for the three months ended September 30, 2021 and 2020, respectively. The effective tax rate differs from the statutory federal income tax rate of 21% for the six months ended September 30, 2021 and 2020 primarily due to a non-deductible charge for in-process research and development related to the preCARDIA acquisition offset by excess tax benefits related to share-based compensation.    The Company recognized excess tax benefits associated with stock-based awards of $9.8 million and $8.5 million for the six months ended September 30, 2021 and 2020, respectively.

The Company is subject to the examination of its income tax returns by the Internal Revenue Service (“IRS”) and other tax authorities. The outcome of these audits cannot be predicted with certainty. The Company’s most recent completed income tax audits were in the U.S. relating to fiscal year 2016 and in Germany, which covered fiscal years 2012 through 2015. These tax audits did not materially impact the financial statements. The Company is currently undergoing an income tax audit by the German tax authorities on Abiomed Europe GMBH and ECP for fiscal years 2016 through 2019. All other tax years remain subject to examination by the federal, state and foreign tax authorities.

Commitments And Contingencies Disclosure [Abstract]

Commitments and Contingencies

Note 16. Commitments and Contingencies

From time to time, the Company is involved in legal and administrative proceedings and claims of various types. In some actions, the claimants seek damages, as well as other relief, which, if granted, would require significant expenditures. The Company records a liability in its consolidated financial statements for these matters when a loss is known or considered probable and the amount can be reasonably estimated. The Company reviews these estimates each accounting period as additional information is known and adjusts the loss provision when appropriate. If a matter is both probable to result in liability and the amount of loss can be reasonably estimated, the Company estimates and discloses the possible loss or range of loss. If the loss is not probable or cannot be reasonably estimated, a liability is not recorded in its consolidated financial statements.

Maquet Matters

In December 2015, the Company received a letter from Maquet Cardiovascular LLC (“Maquet”), a subsidiary of Getinge AB, asserting that the Company’s Impella® devices infringe certain claims with guidewire, lumen, rotor, purge and sensor features, which were in two Maquet patents and one pending patent application (which has since issued as a third patent) in the U.S. and elsewhere, and attaching a draft litigation complaint.  The letter encouraged the Company to take a license from Maquet. In May 2016, the Company filed suit in U.S. District Court for the District of Massachusetts (“D. Mass.” or “the Court”) against Maquet, seeking a declaratory judgment that the Company’s Impella devices do not infringe Maquet’s cited patent rights.  

In August 2016, Maquet sent a letter to the Company identifying four new Maquet U.S. continuation patent filings with claims that Maquet alleges are infringed by the Company’s Impella devices. The four U.S. continuation applications have been issued as patents of Maquet but expired on September 1, 2020.

In September 2016, Maquet filed a response to the Company’s suit in D. Mass., including various counterclaims alleging that the Company’s Impella 2.5®, Impella CP®, Impella 5.0®, and Impella RP® heart pumps infringe certain claims of the three original issued U.S. patents (“2016 Action”). In July 2017, the Court granted a motion to add three of the four additional continuation patents to the 2016 Action.  In April 2018, the Court conducted a Markman hearing on claim interpretation. On September 7, 2018, the judge issued a Memorandum and Order on Claim Construction, where he interpreted the disputed claim terms in the case.  Maquet then filed a motion for reconsideration of the Court’s construction of one of the disputed claim terms. The motion was denied on May 22, 2019. As a result of the Court’s denial, only one of the six originally asserted patents is in dispute. The Company filed a motion for summary judgement (the “MSJ”) for the remaining patent on September 18, 2019 (non-infringement) and April 13, 2020 (invalidity). The parties argued the MSJ for non-infringement on November 19, 2019 and the MSJ for invalidity on August 20, 2020.  

On September 30, 2021, the Court granted the Company’s MSJ for non-infringement of the asserted claims in the remaining patent which expired on September 1, 2020.   On October 20, 2021, Maquet filed a motion for reconsideration of the Order in favor of the Company. The Company intends to file a response to Maquet’s motion in due time.  Because the Court has not yet issued a final judgement, the case is not yet appealable to the Federal Circuit.    

In November 2017, Maquet filed a second action in D. Mass (the “2017 Action”) alleging that the Company’s Impella 2.5®, Impella CP®, and Impella 5.0® heart pumps infringe certain claims of the fourth additional U.S. continuation patent mentioned above (the seventh patent overall). Discovery in the 2017 Action is ongoing.

In a series of letters during January and February 2019, Maquet informed the Company of seven new patent applications filed from the patents in the 2016 Action and 2017 Action with claims Maquet alleges would be infringed by the Impella® products if the new applications were to issue as patents. One of the newly issued patents has been added to the 2017 Action. A Markman hearing for the newly-added patent was held on November 18, 2019.  A Markman order has not been issued yet. The asserted patent in this case expired on September 1, 2020. Discovery remains ongoing.

In the 2016 Action and 2017 Action, Maquet seeks injunctive relief and monetary damages in the form of a reasonable royalty, with three times the amount for alleged willful infringement. In its responses to the Company’s counterclaims, Maquet admits that its current commercially available products do not embody the claims of the asserted patents.

The Company is unable to estimate the potential liability with respect to the legal matters noted above. There are numerous factors that make it difficult to meaningfully estimate possible loss or range of loss at this stage of the legal proceedings, including the significant number of legal and factual issues still to be resolved in the Maquet patent disputes.

Thoratec Matters

Thoratec Corporation (“Thoratec”), a subsidiary of Abbott Laboratories (“Abbott”), has challenged a number of Company-owned patents in Europe in connection with the launch of Thoratec’s HeartMate PHP™ medical device (“PHP”) in Europe and the Company has counterclaimed for infringement in the District Court, or the Court of 1st Instance, in Düsseldorf. The litigation was stayed pending the Federal Court of Justice, the Court of 3rd and Last Instance in Germany for patent infringement cases,  ruling on the validity and scope of the litigated patents. In September 2019, the Federal Court of Justice in Germany upheld the Company’s patents that are the subject of the patent infringement action for the sales and marketing of Thoratec’s PHP pump in Germany. Subsequently, the Court of 1st Instance in Düsseldorf lifted the stay, re-opened the litigation proceedings, and ruled in favor of the Company.  The Court of 1st Instance acknowledged that Thoratec’s PHP product infringes two of the Company’s patents related to the key features of Impella® intravascular pump and future expandable heart pump, known as Impella ECP®.  Abbott appealed and the oral hearing was held on August 26, 2021.  

On September 23, 2021, the Appellate Court (the “Court of 2nd Instance”) in Düsseldorf upheld the ruling by the Court of 1st Instance in both cases and did not allow an appeal to the Federal Court of Justice.  Thoratec has until the end of October 2021 to appeal the Court of 2nd Instance’s order denying appeal in both cases to the Federal Court of Justice.   If Thoratec forgoes the appeal or the case is not heard by Federal Court of Justice, then the verdict will be deemed final and enforceable. The judgement will remain provisionally enforceable until the final resolution, which means that the Company is able to seek a court ordered injunction preventing the sale and marketing by Thoratec of PHP, should Thoratec attempt to launch HeartMate PHP in Germany.

These actions relate solely to Thoratec’s ability to manufacture and sell its PHP product in Europe and have no impact on the Company's ability to manufacture or sell its Impella® line of medical devices.  The actions do not expose the Company to liability risk, except under local German law, which requires a losing party in a proceeding to pay a portion of the other party’s legal fees.

Securities Class Action Litigation

On or about August 6, 2019, the Company received a securities class action complaint filed on behalf of a single shareholder in the U.S. District Court for the Southern District of New York (“SDNY”), on behalf of himself and persons or entities that purchased or acquired the Company’s securities between January 31, 2019 through July 31, 2019. On October 7, 2019, a similar purported class action complaint was filed by a different shareholder on behalf of himself and persons or entities that purchased or acquired the Company’s securities between November 1, 2018 and July 31, 2019. Also, on October 7, 2019, four shareholders filed applications to be appointed lead plaintiff and for their counsel to be appointed lead counsel for the class. Two of those shareholders also filed motions to consolidate the two cases and two of the shareholders have withdrawn their applications to be lead plaintiff.

The complaints alleged that the Company violated Sections 10(b) and 20(a) of and Rule 10b-5 under the Exchange Act, in connection with allegedly misleading disclosures made by the Company regarding its financial condition and results of operations.

On June 29, 2020, SDNY issued an order consolidating the two cases and appointed Local 705 International Brotherhood of Teamsters Pension Fund as the lead plaintiff and Labaton Sucharow LLP as lead counsel.  On September 17, 2020, the lead plaintiff filed an amended complaint in which it proposed a new class period of May 3, 2018 to July 31, 2019. As prescribed by a scheduling order, the Company filed a motion to dismiss on November 16, 2020. On September 21, 2021, SDNY granted the Company’s motion, dismissed the amended complaint, and gave the lead plaintiff leave to move to amend the complaint by October 12, 2021. On October 12, 2021, the Company and the lead plaintiff entered into a stipulation to voluntarily dismiss the securities class action and SDNY ordered dismissal of the case with prejudice on the same day. Under the terms of the stipulation, the lead plaintiff has agreed not to move for leave to amend the complaint and not to appeal the dismissal of the action.  

Shareholder Derivative Litigation

On November 6 and 7, 2019, two shareholders filed derivative actions in SDNY that were subsequently consolidated.  On November 8, 2019, another shareholder filed a derivative action in Massachusetts Suffolk County Superior Court.  On January 7, 2020, another shareholder derivative action was filed in the U.S. District Court for the District of Delaware.  The complaints in these actions rely on many of the same allegations as in the securities class actions, and assert that, between November 1, 2018 and July 31, 2019, the directors of the Company made or allowed to be made misleading public statements regarding the Company’s growth, ultimately harming the Company.  

The Company has agreed with the plaintiffs in all three actions to stay the cases pending resolution of a motion to dismiss in the securities class actions. As a result of the stay, the Delaware action has been administratively closed.

Litigation Demand

On March 3, 2020, a shareholder sent a letter to the Board of Directors asserting that the directors of the Company made or allowed to be made misleading public statements regarding the Company’s growth. The letter relies on many of the same allegations as the securities class actions and derivative actions, and demands that the Board (i) undertake an independent investigation of the directors, (ii) bring suit against the directors on behalf of the Company, and (iii) take a number of additional affirmative actions to redress the purported wrongs. On March 30, 2020, the Company, after discussions with the Board of Directors, sent a written response to the shareholder’s counsel which they responded to on June 1, 2020.  The Company then sent a further response to the shareholder’s counsel on June 15, 2020, affirming the decision to defer consideration of the litigation demand pending further developments in the securities class action suit. Following the filing of the amended complaint in the securities class action, described above, the same shareholder renewed their demand on September 29, 2020.  The Company responded on October 9, 2020 and once again affirmed that it will defer consideration of the demand pending further substantive developments in the securities class action suit.

On November 5, 2020, a second shareholder sent a letter to the Board of Directors that made essentially the same demands as the September 29, 2020 letter from the first shareholder.  The Company responded on November 23, 2020, noting that it will defer consideration of the demand pending further substantive developments in the securities class action suit.  

The Company is unable to estimate the potential liability with respect to the various legal matters noted above. There are numerous factors that make it difficult to estimate reasonably possible loss or range of loss at this stage of the legal proceedings, including the significant number of legal and factual issues still to be resolved in the shareholder derivative litigations.

Basis of Preparation and Summary of Significant Accounting Policies (Policies)

Accounting Policies [Abstract]

COVID-19 Pandemic

COVID-19 Pandemic

The Company is subject to additional risks and uncertainties as a result of the ongoing novel coronavirus (“COVID-19”) pandemic. The ongoing COVID-19 pandemic has adversely impacted and is likely to further adversely impact the Company’s business and markets, including the Company’s workforce and the operations of its customers, suppliers, and business partners. While the COVID-19 (including new variants of COVID-19) pandemic remains fluid and continues to evolve differently across various geographies, the Company believes it is likely to continue to experience variable impacts on its business, including, for example: supply shortages, particularly of its product components; supply chain disruptions, which may limit its ability to manufacture or distribute its products.

The depth and extent to which the COVID-19 pandemic may directly or indirectly impact the Company’s business, results of operations, financial condition and individual markets is dependent upon various factors, including the spread of additional variants; the availability of vaccinations, personal protective equipment, intensive care unit (“ICU”) and operating room capacity, and medical staff; and government interventions to reduce the spread of the virus. During the second quarter of fiscal year 2022, the Company has experienced varying levels of recovery across its product lines and geographic locations from the challenges caused by the pandemic. Despite these improvements, the impact of COVID-19 on the Company’s patient utilization volumes is likely to vary widely by country, region, and type. In particular, Impella product revenue increased in the three and six months ended September 30, 2021 as a result of sales mix and higher patient utilization in the U.S., Germany and Japan as compared to the three and six months ended September 30, 2020, however, in the second quarter of fiscal year 2022, patient utilization of Impella heart pump devices was negatively impacted by an increase in COVID-19 hospitalizations and ongoing shortage of hospital workers that limited ICU capacity which contributed to some deferral of elective procedures. When COVID-19 infection rates spike in a particular region, the Company’s patient utilization volumes have generally been negatively impacted as hospitals face capacity limitations, staffing shortages and some in-patient treatments have been deferred. While the Company believes there may be a backlog of patients in need

of medical attention that requires the use of the Company’s products, it is difficult to predict when or if those patients may ultimately seek treatment, and therefore, the extent to which COVID-19 may impact patient utilization and, consequently, product revenue.

To ensure the health and safety of its global employees, the Company continues to offer onsite COVID-19 testing and vaccinations in order to maintain a safe working environment. The Company’s proactive testing and vaccination programs have reduced exposure with early detection and enabled its manufacturing facilities to operate at full capacity.  

The Company continues to closely monitor the impact of COVID-19 on all aspects of its business and geographies, including any impact on the Company’s customers, employees, suppliers, vendors, business partners and distribution channels, as well as on procedures and the demand for its products by keeping apprised of local, regional, and global COVID-19 surges (including new variants of the virus). As of the date of issuance of these financial statements, the extent to which the COVID-19 pandemic may lead materially adversely affect the Company’s financial condition, liquidity or results of operations is uncertain.

Recently Adopted Accounting Pronouncements

Recently Adopted Accounting Pronouncements

In December 2019, the Financial Accounting Standards Board (“FASB”) issued ASU 2019-12, Simplifying the Accounting for Income Taxes (ASC 740). The ASU enhances and simplifies various aspects of the income tax accounting guidance in ASC 740, including requirements related to hybrid tax regimes, the tax basis step-up in goodwill obtained in a transaction that is not a business combination, separate financial statements of entities not subject to tax, the intra-period tax allocation exception to the incremental approach, ownership changes in investments, changes from a subsidiary to an equity method investment, interim-period accounting for enacted changes in tax law, and the year-to-date loss limitation in interim-period tax accounting. This guidance is effective for the Company for annual and interim periods beginning after December 31, 2020; however, early adoption is permitted. The Company adopted this standard as of April 1, 2021 on a prospective basis. The adoption did not have a material impact on the Company’s condensed consolidated financial statements.

In January 2020, the FASB issued ASU 2020-01, “Investments—Equity Securities (Topic 321), Investments—Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815),” an amendment clarifying the interaction between accounting standards related to equity securities, equity method investments, and certain derivative instruments. The guidance is effective for fiscal years beginning after December 15, 2020. The Company adopted this standard as of April 1, 2021 and the adoption did not have a material impact on the Company’s condensed consolidated financial statements.
