NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

Note 1. Basis of Presentation

HeartWare International, Inc., referred to in these notes collectively with its subsidiaries HeartWare Pty. Limited, HeartWare, Inc., HeartWare (UK) Limited, HeartWare GmbH and HeartWare France as “we,” “our,” “HeartWare” or the “Company,” is a medical device company that develops, manufactures and markets miniaturized implantable heart pumps, or ventricular assist devices, to treat patients suffering from advanced heart failure.

The accompanying unaudited interim condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for reporting of interim financial information. Pursuant to such rules and regulations, certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted. Accordingly, these statements do not include all the disclosures normally required by accounting principles generally accepted in the United States for annual financial statements and should be read in conjunction with Management’s Discussion and Analysis of Financial Condition and Results of Operations contained in this report and the audited financial statements and notes thereto included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2011. The accompanying condensed consolidated balance sheet as of December 31, 2011 has been derived from our audited financial statements. The condensed consolidated statements of operations for the three and six months ended June 30, 2012 and cash flows for the six months ended June 30, 2012 are not necessarily indicative of the results to be expected for any future period or for the year ending December 31, 2012.

In the opinion of management, the accompanying unaudited interim condensed consolidated financial statements contain all adjustments (consisting of only normally recurring adjustments) necessary to present fairly the financial position and results of operations as of the dates and for the periods presented.

Note 2. Liquidity

At June 30, 2012, we had approximately $131.0 million of cash, cash equivalents and investments. The accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States, which contemplate continuation of the Company as a going concern. We have incurred substantial losses from operations since our inception, and such losses have continued through June 30, 2012. At June 30, 2012, we had an accumulated deficit of approximately $224.0 million.

We have financed our operations primarily through the issuance of shares of our common stock and the issuance of convertible notes. Most recently, in December 2010, we consummated the issuance and sale of $143.75 million aggregate principal amount of convertible notes. The convertible notes are the senior unsecured obligations of the Company. The convertible notes bear interest at a rate of 3.5% per annum, payable semi-annually in arrears on June 15 and December 15 of each year. The convertible notes will mature on December 15, 2017, unless earlier repurchased or converted. The convertible notes will be convertible at an initial conversion rate of 10 shares of common stock per $1,000 principal amount of convertible notes, which corresponds to an initial conversion price of $100.00 per share of common stock.

For the remainder of 2012, our cash, cash equivalents and investments are expected to primarily be used to fund our ongoing operations including preparing the launch of the HeartWare^® Ventricular Assist System (the “HeartWare System”) in the United States, research and development of new products, managing on-going and new clinical trials, and regulatory and other compliance functions, as well as for general working capital. We believe our cash, cash equivalents and investment balances are sufficient to support our planned operations for at least the next twelve months.

Note 3. Significant Accounting Policies

Principles of Consolidation

The condensed consolidated financial statements include the accounts of HeartWare International, Inc., and its subsidiaries described in Note 1. All inter-company balances and transactions have been eliminated in consolidation. We hold certain investments in small development stage entities. In accordance with FASB ASC 810, we analyzed the investments to determine if the investments are variable interests or interests that gave us a controlling financial interest in a variable interest entity (“VIE”). As of June 30, 2012, we determined there were no VIE’s required to be consolidated, because we are not the primary beneficiary, as we do not have the power to direct the most meaningful activities of the VIE. Investments where the Company does not exercise operating and financial control are accounted for under the equity method or cost method depending on our respective ownership interest.

Accounting Estimates

The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from those estimates.

Cash and Cash Equivalents

Cash and cash equivalents are recorded on our condensed consolidated balance sheets at cost, which approximates fair value. All highly liquid investments with an original maturity of three months or less at the date of purchase are considered to be cash equivalents.

Investments

Our investments classified as available-for-sale are stated at fair value with unrealized gains and losses reported in accumulated other comprehensive loss within stockholders’ equity. We classify our available-for-sale investments as short-term if their remaining time to maturity at purchase is beyond three months, but less than twenty-four months. Investments with maturities beyond one year may be classified as short-term based on their highly liquid nature and because such marketable securities represent the investment of cash that is available for current operations. Interest on investments classified as available-for-sale is included in investment income, net. Premiums paid on our short-term investments are amortized over the remaining term of the investment and such amortization is included in investment income, net.

Receivables

Accounts receivable consists of amounts due from the sale of our HeartWare System to our customers, which include hospitals, health research institutions and medical device distributors. We grant credit to customers in the normal course of business, but do not require collateral or any other security to support credit sales. Our receivables are geographically dispersed, with a significant portion from customers located in Europe and other foreign countries. At June 30, 2012, one customer had an accounts receivable balance representing approximately 20% of our total accounts receivable. At December 31, 2011, no customer had an accounts receivable balance greater than 10% of our total accounts receivable.

We maintain allowances for doubtful accounts for estimated losses that may result from an inability to collect payments owed to us for product sales. We regularly review the allowance by considering factors such as historical experience, the age of the accounts receivable balances and current economic conditions that may affect a customer’s ability to pay. Account balances are charged off against the allowance after appropriate collection efforts are exhausted and we feel it is probable that the receivable will not be recovered.

11

The following table summarizes the change in our allowance for doubtful accounts for the six months ended June 30, 2012 and 2011:

	2012		2011
	(in thousands)
Beginning balance	$	500	$	600
Additions (bad debt expense)		250		300
Deductions (charge-offs)		—		—
Ending balance	$	750	$	900

As of June 30, 2012 and December 31, 2011, we did not have an allowance for returns.

Inventories, net

Inventories are stated at the lower of cost or market. Cost is determined using a first-in, first-out, or FIFO, method. Work-in-process and finished goods manufactured or assembled by us include direct and indirect labor and manufacturing overhead. Finished goods include product which is ready-for-use and which is held by us or by our customers on a consignment basis.

We review our inventory for excess or obsolete inventory and write-down obsolete or otherwise unmarketable inventory to its estimated net realizable value. Obsolescence may occur due to product expiring or product improvements rendering previous versions obsolete.

Deferred Financing Costs

Costs incurred in connection with the issuance of our convertible senior notes have been allocated between the liability component and the equity component as further discussed in Note 10. The liability component of the issuance costs incurred was capitalized and is included in deferred financing costs, net on our condensed consolidated balance sheets. These costs are being amortized using the effective interest method through December 15, 2017, the maturity date of the notes, and such amortization expense is reflected in interest expense on our condensed consolidated statements of operations. The amount of amortization for the three months ended June 30, 2012 and 2011 was approximately $0.1 million for each period. The amount of amortization for the six months ended June 30, 2012 and 2011 was approximately $0.2 million and $0.1 million, respectively. The amount of accumulated amortization at June 30, 2012 and December 31, 2011 was approximately $0.5 million and $0.3 million, respectively.

Product Warranty

Certain patient accessories sold with the HeartWare System are covered by a limited warranty ranging from one to two years. Estimated contractual warranty obligations are recorded as an expense when the related revenue is recognized and are included in cost of revenue on our condensed consolidated statements of operations. Factors that affect estimated warranty liability include the number of units sold, historical and anticipated rates of warranty claims, cost per claim, and vendor supported warranty programs. We periodically assess the adequacy of our recorded warranty liabilities and adjust the amounts as necessary.

The amount of the liability recorded is equal to the estimated costs to repair or otherwise satisfy claims made by customers. Accrued warranty expense is included as a component of other accrued liabilities on our condensed consolidated balance sheets.

The costs to repair or replace products associated with product recalls and voluntary service campaigns are recorded when they are determined to be probable and reasonably estimable as a cost of revenue and are not included in product warranty liability. No such costs were incurred in the three and six months ended June 30, 2012 and 2011.

12

The following table summarizes the change in our warranty liability for the six months ended June 30, 2012 and 2011:

	2012			2011
	(in thousands)
Beginning balance	$	203		$	291
Accrual for (reversal of) warranty expense		449			(21	)
Warranty costs incurred during the period		(385	)		(28	)
Ending balance	$	267		$	242

Leases

We lease all of our administrative and manufacturing facilities. We recognize rent expense on a straight-line basis over the terms of our leases. Any scheduled rent increases, rent holidays and other related incentives are recognized on a straight-line basis over the terms of the leases. The difference between the cash rental payments and the straight-line recognition of rent expense over the terms of the leases results in a deferred rent asset or liability. As of June 30, 2012, the long-term portion of our deferred rent liability of approximately $2.9 million is included in other long-term liabilities on our condensed consolidated balance sheets.

Fair Value Measurements

The carrying amounts reported on our condensed consolidated balance sheets for cash and cash equivalents, accounts receivable, accounts payable and other accrued liabilities approximate their fair value based on the short-term maturity of these instruments. Investments are considered available-for-sale as of June 30, 2012 and December 31, 2011 and are carried at fair value. See Note 4, “Fair Value Measurements” and Note 10, “Debt” for more information.

Vendor Concentration

For the three and six months ended June 30, 2012, we purchased approximately 70% and 71%, respectively, of our inventory components and supplies from three vendors. For the three and six months ended June 30, 2011, we purchased approximately 59% and 58%, respectively of our inventory components and supplies from the same three vendors. In addition, one of these vendors supplies consulting services and material used in research and development activities. As of June 30, 2012 and 2011, the amounts due to these vendors totaled approximately $1.6 million and $1.0 million, respectively.

We purchase certain important components of the HeartWare System from single-source suppliers. We cannot guarantee that we can secure alternative suppliers that could provide similar components on comparable terms. A change in suppliers could cause a delay in manufacturing and a possible loss of product sales or result in higher component costs, all of which would have a negative effect on our results of operations.

Concentration of Credit Risk and other Risks and Uncertainties

Financial instruments that potentially expose us to concentrations of credit risk consist primarily of cash and cash equivalents, investments and trade accounts receivable. Cash and cash equivalents are primarily on deposit with financial institutions in the United States and these deposits generally exceed the amount of insurance provided by the Federal Deposit Insurance Corporation (the “FDIC”). The Company has not experienced any historical losses on its deposits of cash and cash equivalents. Our investments consist of investment grade rated corporate and government agency debt and time deposits.

13

Concentration of credit risk with respect to our trade accounts receivable from our customers is primarily limited to hospitals, health research institutions and medical device distributors. Credit is extended to our customers, based on an evaluation of a customer’s financial condition and collateral is not required.

We are subject to certain risks and uncertainties including, but not limited to, our ability to achieve profitability, to generate cash flow sufficient to satisfy our indebtedness, to run clinical trials in order to receive and maintain FDA and foreign regulatory approvals for our products, the ability to achieve widespread acceptance of our product, our ability to manufacture our products in a sufficient volume and at a reasonable cost, the ability to protect our proprietary technologies and develop new products, the risks associated with operating in foreign countries, and general competitive and economic conditions. Changes in any of the preceding areas could have a material adverse effect on our business, results of operations or financial position.

New Accounting Standards

In June 2011, the FASB issued ASU No. 2011-05,Comprehensive Income (Topic 220): Presentation of Comprehensive Income. ASU No. 2011-05 requires an entity to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income, or in two separate but consecutive statements. ASU No. 2011-05 eliminates the option to present components of other comprehensive income as part of the statement of stockholders’ equity. The presentation requirements became effective for us on January 1, 2012. The adoption of ASU No. 2011-05 did not affect our consolidated financial position, results of operations or cash flows.

Note 4. Fair Value Measurements

FASB ASC 820 –Fair Value Measurements and Disclosures, defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. FASB ASC 820 requires disclosures about the fair value of all financial instruments, whether or not recognized, for financial statement purposes. Disclosures about the fair value of financial instruments are based on pertinent information available to us as of the reporting dates. Accordingly, the estimates presented in these condensed consolidated financial statements are not necessarily indicative of the amounts that could be realized on disposition of the financial instruments.

FASB ASC 820 specifies a hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect market assumptions. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurement) and the lowest priority to unobservable inputs (Level 3 measurement).

The three levels of the fair value hierarchy are as follows:

Level 1 – Quoted prices for identical instruments in active markets.

Level 2 – Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable.

Level 3 – Instruments with primarily unobservable value drivers.

The following table represents the fair value of our financial assets and financial liabilities measured at fair value on a recurring basis and which level was used in the fair value hierarchy.

Note 10. Debt

On December 15, 2010, we completed the sale of 3.5% convertible senior notes due 2017 (the “Convertible Notes”) for an aggregate principal amount of $143.75 million pursuant to the terms of an Indenture dated December 15, 2010. The Convertible Notes are the senior unsecured obligations of the Company. The Convertible Notes bear interest at a rate of 3.5% per annum, payable semi-annually in arrears on June 15 and December 15 of each year. The Convertible Notes will mature on December 15, 2017, unless earlier repurchased by us or converted.

The Convertible Notes will be convertible at an initial conversion rate of 10 shares of our common stock per $1,000 principal amount of Convertible Notes, which corresponds to an initial conversion price of $100.00 per share of our common stock. The conversion rate is subject to adjustment from time to time upon the occurrence of certain events.

Prior to June 15, 2017, holders may convert their Convertible Notes at their option only upon satisfaction of one or more conditions relating to the sale price of our common stock, the trading price per $1,000 principal amount of Convertible Notes or specified corporate events. On or after June 15, 2017, until the close of business of the business day immediately preceding the date the Convertible Notes mature, holders may convert their Convertible Notes at any time, regardless of whether any of the foregoing conditions have been met. As of the date of this report, none of the events that would allow holders to convert their Convertible Notes have occurred. Upon conversion, we will pay or deliver, as the case may be, cash, shares of our common stock or a combination thereof, at our election.

We may not redeem the Convertible Notes prior to maturity. Holders of the Convertible Notes may require us to purchase for cash all or a part of their Convertible Notes at a repurchase price equal to 100% of the principal amount of the Convertible Notes to be repurchased, plus accrued and unpaid interest, upon the occurrence of certain fundamental changes (as defined in the Indenture) involving the Company. The Indenture does not contain any financial or operating covenants or restrictions on the payments of dividends, the incurrence of indebtedness or the issuance or repurchase of securities by us or any of our subsidiaries.

The Indenture contains customary terms and nonfinancial covenants and defines events of default. If an event of default (other than certain events of bankruptcy, insolvency or reorganization) involving the Company occurs and is continuing, the Trustee (by notice to the Company) or the holders of at least 25% in principal amount of the outstanding Convertible Notes (by notice to the Company and the Trustee) may declare 100% of the principal of and accrued and unpaid interest, if any, on all the Convertible Notes to be due and payable. In case of certain events of bankruptcy, insolvency or reorganization, involving the Company, 100% of the principal of and accrued and unpaid interest on the Convertible Notes will automatically become due and payable. Upon a declaration of acceleration, principal and accrued and unpaid interest, if any, will be due and payable immediately. Notwithstanding the foregoing, the Indenture provides that, to the extent we elect, the sole remedy for an event of default relating to certain failures by us to comply with certain reporting covenants in the Indenture consists exclusively of the right to receive additional interest on the Convertible Notes.

17

In accordance with ASC 470-20,Debt, which applies to certain convertible debt instruments that may be settled in cash or other assets, or partially in cash, upon conversion, we recorded the long-term debt and equity components on our Convertible Notes separately on the issuance date. The amount recorded for long-term debt was determined by measuring the fair value of a similar liability that does not have an associated equity component. The measurement of fair value required the Company to make estimates and assumptions to determine the present value of the cash flows of the Convertible Notes, absent the conversion feature. This treatment increased interest expense associated with our Convertible Notes by adding a non-cash component to interest expense in the form of amortization of a debt discount calculated based on the difference between the 3.5% cash coupon rate and the effective interest rate on debt borrowing of approximately 12.5%. The discount is being amortized to interest expense through the December 15, 2017 maturity date of the Convertible Notes using the effective interest method and is included in interest expense on our condensed consolidated statements of operations. Additionally, we allocated the costs related to issuance of the Convertible Notes on the same percentage as the long-term debt and equity components, such that a portion of the costs is allocated to the long-term debt component and the equity component included in additional paid-in capital. The portion of the costs allocated to the long-term debt component is presented as deferred financing costs, net on our condensed consolidated balance sheets. These deferred financing costs are also being amortized to interest expense through the December 15, 2017 maturity date of the Convertible Notes using the effective interest method and such amortization is included in interest expense on our condensed consolidated statements of operations

The Convertible Notes and the equity component, which is recorded in additional paid-in-capital, consisted of the following:

	June 30,			December 31,
	2012			2011
	(in thousands)
Principal amount	$	143,750		$	143,750
Unamortized discount		(46,545	)		(49,473	)
Net carrying amount	$	97,205		$	94,277
Equity component	$	55,038		$	55,038

Based on the initial conversion rate of 10 shares of our common stock per $1,000 principal amount of Convertible Notes, which corresponds to an initial conversion price of $100.00 per share of our common stock, the number of shares issuable upon conversion of the Convertible Notes is 1,437,500. The value of these shares, based on the closing price of our common stock on June 29, 2012 of $88.80, was approximately $127.7 million. The fair value of our Convertible Notes as presented in Note 4 was $166.9 million at June 30, 2012.

Interest expense related to the Convertible Notes consisted of interest due on the principal amount, amortization of the discount and amortization of the portion of the deferred financing costs allocated to the long-term debt component. For the three and six months ended June 30, 2012 and 2011, interest expense related to the Convertible Notes was as follows:

	Three Months Ended June  30,				Six Months Ended June 30,
	2012		2011		2012		2011
	(in thousands)

Note 11. Stockholders’ Equity

In the six months ended June 30, 2012, we issued an aggregate of 31,820 shares of our common stock upon the exercise of stock options and an aggregate of 34,721 shares of our common stock upon the vesting of restricted stock units.

In the six months ended June 30, 2011, we issued an aggregate of 17,606 shares of our common stock upon the exercise of stock options and an aggregate of 29,692 shares of our common stock upon the vesting of restricted stock units.

Note 12. Share-Based Compensation

We recognize share-based compensation expense related to our stock options and restricted stock units (“RSU’s) based on the estimated fair value of the awards on the date of the grant, net of estimated forfeitures, using an accelerated accrual method over the vesting period. Vesting of share-based awards issued with performance-based vesting criteria must be probable before we begin recording share-based compensation expense. At each reporting period, we review the likelihood that these awards will vest and if vesting is deemed probable, we begin to recognize compensation expense at that time. If ultimately performance goals are not met, for any awards where vesting was previously deemed probable, previously recognized compensation expense will be reversed.

We allocate share-based compensation expense to cost of revenue, selling, general and administrative expense and research and development expense based on the award holders’ employment function. For the three and six months ended June 30, 2012 and 2011, we recorded share-based compensation expense as follows:

	Three Months Ended June  30,				Six Months Ended June 30,
	2012		2011		2012		2011
	(In thousands)
Cost of revenues	$	1,022	$	533	$	1,754	$	1,119
Selling, general and administrative		3,606		2,209		5,487		3,653
Research and development		1,713		759		2,814		1,665
	$	6,341	$	3,501	$	10,055	$	6,437

A reduction in our estimated forfeiture rate resulted in approximately $1.9 million of additional share-based compensation expense for the three and six months ended June 30, 2012.

No deferred tax benefits were attributed to our share-based compensation expense recorded in the accompanying condensed consolidated financial statements because we are in a net operating loss position and a full valuation allowance is maintained for all net deferred tax assets. We receive a tax deduction for certain stock option exercises during the period the options are exercised, and for the vesting of restricted stock units during the period the restricted stock units vest. For stock options, the amount of the tax deduction is generally for the excess of the fair market value of our shares of common stock over the exercise price of the stock options at the date of exercise. For restricted stock units, the amount of the tax deduction is generally for the fair market value of our shares of common stock at the vesting date. Excess tax benefits are not included in the accompanying condensed consolidated financial statements because we are in a net operating loss position and a full valuation allowance is maintained for all net deferred tax assets.

Equity Plans

We have issued share-based awards to employees, non-executive directors and outside consultants through various approved plans and outside of any formal plan. New shares are issued upon the exercise of share-based awards.

19

On August 5, 2008, we adopted the HeartWare International, Inc. 2008 Stock Incentive Plan (“2008 SIP”). The 2008 SIP allowed for the issuance of share-based awards to employees, directors and consultants. We have issued options and RSU’s to employees and directors under the 2008 SIP. As noted below, subsequent to adoption of the HeartWare International, Inc. 2012 Incentive Award Plan, no new awards will be granted under the 2008 SIP.

Upon receipt of stockholder approval on May 31, 2012, we adopted the HeartWare International, Inc. 2012 Incentive Award Plan (“2012 Plan”). The 2012 Plan provides for the grant of incentive stock options, non-qualified stock options, restricted stock, restricted stock units, performance awards, dividend equivalent rights, deferred stock, deferred stock units, stock payments and stock appreciation rights (collectively referred to as “Awards”), to our directors, employees and consultants. Under the terms of the 2012 Plan, the total number of shares of our common stock initially reserved for issuance under Awards is 1,375,000, provided that the total number of shares of our common stock that may be issued pursuant to “Full Value Awards” (Awards other than options, SARs or other awards for which the holder pays the intrinsic value existing as of the date of grant whether directly or by forgoing a right to receive a payment from the company) is 1,275,000. As of June 30, 2012, no awards had been issued under the 2012 Plan. Subsequent to adoption of the 2012 Plan, no new awards will be granted under the 2008 SIP (or prior plans). Any outstanding awards under the 2008 SIP and any other plans will continue to be subject to the terms and conditions of the plan from which they were granted.

Stock Options

Each option allows the holder to subscribe for and be issued one share of our common stock at a specified price, which is generally the quoted market price of our common stock on the date the option is issued. Options generally vest on a pro-rata basis on each anniversary of the issuance date within four years of the date the option is issued or vest in accordance with performance-based criteria. Options may be exercised after they have vested and prior to the specified expiry date provided applicable exercise conditions are met, if any. The expiry date can be for periods of up to ten years from the date the option is issued.

Performance-based options vest in four equal tranches contingent upon the achievement of pre-determined corporate milestones related primarily to the development of our products and the achievement of certain prescribed clinical and regulatory objectives. Any performance-based options that have not vested after five years from the date of grant automatically expire.

The fair value of each option is estimated on the date of grant using the Black-Scholes option pricing model using the assumptions established at that time. The following table includes the weighted average assumptions used for options issued in the three and six months ended June 30, 2012 and 2011.

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

Information related to options granted under all of our plans at June 30, 2012 and activity in the six months then ended is as follows (certain amounts in U.S.$ were converted from AU$ at the then period-end spot rate):

	Number of Options (in thousands)			Weighted Average Exercise Price		Weighted Average Remaining Contractual Life (Years)		Aggregate Intrinsic Value (in thousands)
Outstanding at December 31, 2011		381		$	34.79
Granted		7			81.37

Exercisable at June 30, 2012		260		$	34.09		4.75	$	14,239

The aggregate intrinsic values at June 30, 2012 noted in the table above represent the closing price of our common stock traded on NASDAQ, less the weighted average exercise price at period end multiplied by the number of options outstanding or exercisable.

At June 30, 2012, 16,791 of the options outstanding that are not yet exercisable are subject to performance-based vesting criteria as described above.

The weighted average grant date fair value per share of options issued in the six months ended June 30, 2012 and 2011 was $43.83 and $44.36 per share, respectively.

The total intrinsic value of options exercised in the six months ended June 30, 2012 was approximately $1.4 million. Cash received from options exercised in the six months ended June 30, 2012 was approximately $1.1 million. The total intrinsic value of options exercised in the six months ended June 30, 2011 was approximately $1.0 million. Cash received from options exercised in the six months ended June 30, 2011 was approximately $0.6 million.

At June 30, 2012, there was approximately $1.0 million of unrecognized compensation expense related to non-vested option awards, including performance-based options not yet deemed probable of vesting. The expense is expected to be recognized over a weighted average period of 0.9 years.

Restricted Stock Units

RSU’s issued under the plans vest on a pro-rata basis on each anniversary of the issuance date over three or four years or vest in accordance with performance-based criteria. The RSU’s with performance-based vesting criteria vest in tranches contingent upon the achievement of pre-determined corporate milestones related primarily to the development of our products and the achievement of certain prescribed clinical and regulatory objectives. RSU’s with performance-based vesting criteria not vested after five years from the date of grant automatically expire. There is no consideration payable on the vesting or exercise of RSU’s issued under the plans. Upon vesting, the RSU’s are exercised automatically and settled in shares of our common stock.

Information related to RSU’s at June 30, 2012 and activity in the six months then ended is as follows:

	Number of Units (in thousands)			Weighted Average Remaining Contractual Life (Years)		Aggregate Intrinsic Value (in thousands)
Outstanding at December 31, 2011		635
Granted		48
Vested/Exercised		(35	)

Expired		—
Outstanding at June 30, 2012		637			1.44	$	56,597
Exercisable at June 30, 2012		—			—	$	—

The aggregate intrinsic value at June 30, 2012 noted in the table above represents the closing price of our common stock traded on NASDAQ, multiplied by the number of RSU’s outstanding.

21

At June 30, 2012, 39,117 of the RSU’s outstanding that are not yet exercisable are subject to performance-based vesting criteria as described above.

The total intrinsic value of RSU’s vested in the six months ended June 30, 2012 and 2011 was approximately $2.7 million and $2.5 million, respectively.

The fair value of each RSU award equals the closing price of our common stock on the date of grant. The weighted average grant date fair value per share of RSU’s granted in the six months ended June 30, 2012 and 2011 was $80.67 and $78.77, respectively.

At June 30, 2012, we had approximately $21.1 million of unrecognized compensation expense related to non-vested RSU awards, including awards not yet deemed probable of vesting. The expense is expected to be recognized over a weighted average period of 1.4 years.

Note 13. Net Loss Per Common Share

Basic net loss per common share is computed by dividing net loss for the period by the weighted-average number of common shares outstanding during the period. Diluted net loss per common share adjusts basic net loss per share for the dilutive effects of convertible securities, share-based awards and other potentially dilutive instruments only in the periods in which such effect is dilutive. Due to our net loss for all periods presented, all potentially dilutive instruments were excluded because their inclusion would have been anti-dilutive. The following instruments have been excluded from the calculation of diluted net loss per share, as their effect would be anti-dilutive.

Note 14. Business Segment, Geographic Areas and Major Customers

For financial reporting purposes, we have one reportable segment which designs, manufactures and markets medical devices for the treatment of advanced heart failure. Products are sold to customers located in the United States through our clinical trials, as commercial products to customers in Europe and under special access in other countries. Product sales attributed to a country or region are based on the location of the customer to whom the products are sold. Long-lived assets are primarily held in the United States.

Product sales by geographic location were as follows:

	$	29,053	$	20,389	$	55,398	$	38,364

22

Revenue from U.S. sources for the three and six months ended June 30, 2012 is lower than comparable periods in 2011 due to variability in clinical enrollment. We completed enrollment in our Destination Therapy trial in May 2012. As the majority of our revenue is generated outside of the U.S., we are dependent on favorable economic and regulatory environments for our products in Europe and other countries outside of the U.S. For the three and six months ended June 30, 2012, no customers exceeded 10% of product sales individually. For the three and six months ended June 30, 2011, one customer accounted for approximately 11% and 10%, respectively, of product sales in the aggregate.

Note 15. Commitments and Contingencies

At June 30, 2012, we had purchase order commitments of approximately $18.4 million related to product costs, supplies, services and property, plant and equipment purchases. Many of our materials and supplies require long lead times and as such purchase order commitments reflect materials that may be received up to one year from the date of order.

Litigation

From time to time we may be involved in litigation or other contingencies arising in the ordinary course of business. Except as set forth below or in our Annual Report on Form 10-K for the fiscal year ended December 31, 2011, and based on the information presently available, management believes that there are no contingencies, claims or actions, pending or threatened, the ultimate resolution of which will have a material adverse effect on our financial position, liquidity or result of operations.

On February 24, 2010, we received a letter from two holders of Series A Preferred Stock in HeartWare, Inc., an indirect subsidiary of HeartWare International, Inc. These holders requested various financial and other information regarding HeartWare, Inc. for the purpose of determining the Company’s compliance with their rights as holders of Series A Preferred Stock, including whether a liquidation event has occurred since inception in 2003. HeartWare, Inc. issued Series A-1 and Series A-2 Preferred Stock to certain equity holders of Kriton Medical, Inc. when HeartWare, Inc. purchased out of bankruptcy substantially all of the assets of Kriton in July 2003. The Series A-1 and Series A-2 Preferred Stock do not have voting or dividend rights but entitle the holders thereof to receive, upon certain liquidation events of HeartWare, Inc. (but not the liquidation of or change of control of HeartWare International, Inc.), an amount equal to $10 per share of Series A-1 and $21 per share of Series A-2. The aggregate liquidation preference payment obligation totals approximately $15 million.

On June 27, 2011, HeartWare International, Inc. and HeartWare, Inc., along with HeartWare’s directors, certain officers and a significant stockholder, were named as defendants in a putative class action lawsuit filed in Massachusetts state court by two other Series A Preferred Stockholders on behalf of all holders of Series A Preferred Stock. The complaint alleges that the defendants breached their fiduciary and contractual obligations to Series A Preferred Stockholders by preventing them from receiving a payment of the liquidation preference in connection with certain corporate transactions, including a transaction in 2005 in which HeartWare, Inc. was acquired by HeartWare Limited, a subsidiary of HeartWare International, Inc. The plaintiffs seek monetary damages, interest, costs and limited equitable relief. We do not believe HeartWare International, Inc., HeartWare, Inc. or any of our directors, officers or stockholders have abrogated the rights, or in any way failed to satisfy obligations owed to, any of our stockholders, including holders of Series A Preferred Stock. On September 12, 2011, the defendants served on plaintiffs a motion to dismiss the complaint with prejudice. On February 3, 2012, counsel for plaintiffs and defendants entered into a Memorandum of Understanding to settle the matter. Defendants have agreed to pay up to $1.1 million to participating putative class members in exchange for a full and unconditional release of all claims asserted in the litigation, including any and all claims arising from any right to receive a payment upon any liquidation or deemed liquidation event that has arisen or may arise in the future. On March 22, 2012, the parties filed with the court a stipulation of settlement

23

formalizing the settlement agreement. Shortly thereafter, plaintiffs caused notice of the settlement to be made to putative class members. Following a hearing on July 25, 2012, the court entered judgment granting plaintiffs’ motion to finally approve the settlement, including the full and unconditional release of all present and future claims to receive the liquidation preference.

In accordance with ASC 450, Contingencies, we accrue loss contingencies including costs of settlement, damages and defense related to litigation to the extent they are probable and reasonably estimable. Otherwise, we expense these costs as incurred. If the estimate of a probable loss is a range and no amount within the range is more likely, we accrue the minimum amount of the range. At December 31, 2011, we determined that settlement of the litigation discussed above was probable and that the reasonably estimable settlement amount is $1.1 million. Accordingly, we recorded a liability for the $1.1 million, a $0.2 million receivable from one of the co-defendants, who is a related party. In the six months ended June 30, 2012, we deposited $50,000 in escrow in connection with the potential settlement. As a result of the settlement approval we recorded a receivable at June 30, 2012 in the amount of $0.8 million representing the estimated contribution we will receive from our insurance carrier in connection with the settlement of this litigation. The anticipated insurance recovery is included in selling, general and administrative expenses in our statement of operations.

Milestone Payment

In connection with the purchase of the assets from Kriton Medical, we entered into a settlement and release agreement pursuant to which we are required to make a milestone payment of $1.25 million within 6 months of the date when the first circulatory assist device is approved for sale in the United States, provided that we have at least $25 million in cash on hand and, if we do not have $25 million at that time, then the payment is deferred until such time that we have $25 million in cash on hand. On April 25, 2012, the FDA’s Circulatory System Devices Advisory Committee voted 9 to 2 that the benefits outweigh the risks for the use of the HeartWare System as a bridge to heart transplantation in patients with end-stage heart failure. The Advisory Committee’s recommendation, while not binding, will be considered by the FDA in its review of the Premarket Approval (PMA) application that HeartWare submitted for the HeartWare System in December 2010. Approval of the PMA application will result in this contingent liability being recognized. We will record the effect of this payment obligation when and if this event occurs.

Note 16. Subsequent Events

Acquisition of World Heart

On August 2, 2012, we completed the acquisition of 100% of the outstanding shares of World Heart Corporation (“World Heart”) for consideration of $8.0 million in the form of approximately 83,000 shares of HeartWare International common stock. The acquisition will expand our intellectual property and technology portfolio. In accordance with accounting standards for business combinations, we will account for the acquisition of World Heart under the acquisition method. Under the acquisition method, the assets and liabilities assumed at the date of acquisition are to be recorded in the consolidated financial statements at their respective fair values at the acquisition date. The excess of the purchase price over the fair value of the acquired net assets, if any, will be recorded as goodwill. We have expensed all legal, consulting and other costs related to the acquisition and have included these costs in selling, general and administrative expenses in our statements of operations. World Heart's results of operations will be included in our consolidated financial statements from the date of acquisition.

24

We have evaluated events and transactions that occurred subsequent to June 30, 2012 through the date the financial statements were issued, for potential recognition or disclosure in the accompanying condensed consolidated financial statements. Except as disclosed above, we did not identify any events or transactions that should be recognized or disclosed in the accompanying condensed consolidated financial statements.

ITEM 2: MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis of our financial condition and results of operations should be read together with our unaudited interim condensed consolidated financial statements and related notes appearing elsewhere in this Quarterly Report on Form 10-Q. Certain abbreviated key terms have the meanings defined elsewhere in this Quarterly Report on Form 10-Q.

Overview

HeartWare is a medical device company that develops, manufactures and markets miniaturized implantable heart pumps, or ventricular assist devices, to treat patients suffering from advanced heart failure.

The HeartWare^® Ventricular Assist System (the “HeartWare System”), which includes a ventricular assist device (“VAD”), or blood pump, patient accessories and surgical tools, is designed to provide circulatory support for patients in the advanced stage of heart failure. The core of the HeartWare System is a proprietary continuous flow blood pump, the HVAD^® Pump, which is a full-output device capable of pumping up to 10 liters of blood per minute. The HeartWare System is designed to be implanted adjacent to the heart, avoiding the abdominal surgery generally required to implant similar devices.

In 2009, we received CE Marking for the HeartWare System in the European Union and in March 2011 we received approval from the Therapeutic Goods Administration in Australia allowing for commercial sale and distribution of our device. In the U.S., our device is the subject of clinical trials for two indications: bridge-to-transplant and destination therapy. Our device is also available in other countries around the world under special access programs and limited commercial availability.

Recent key milestones in the development and commercialization of the HeartWare System include the following:

• In May 2012, we received an expanded European label for long-term use of the HeartWare System in all patients at risk of death from refractory, end-stage heart failure.

• In May 2012, results from our ADVANCE bridge-to-transplant clinical trial were published in the American Heart Association's journalCirculation.

• In May 2012, we completed enrollment of our ENDURANCE destination therapy clinical trial. In July 2012, we requested from the U.S. Food and Drug Administration’s (FDA) approval to implant additional Destination Therapy patients under a Continued Access Protocol (CAP) in U.S. centers that implanted a patient in the ENDURANCE trial.

• On April 25, 2012, the FDA’s Circulatory System Devices Advisory Committee voted 9 to 2 that the benefits outweigh the risks for the use of the HeartWare System as a bridge to heart transplantation in patients with end-stage heart failure.

• In March 2012, the FDA approved an Investigational Device Exemption Supplement that allows us to enroll a fourth allotment, of 54 additional patients, in our ADVANCE bridge-to-transplant clinical trial under a CAP. In three prior CAP allotments granted by FDA, 202 patients were enrolled between April 2010 and December 2011.

Beyond the HeartWare System, we are also evaluating our next generation device, the MVAD^® Pump. The MVAD Pump is a development-stage miniature ventricular assist device, approximately one-third the size of the HVAD Pump. The MVAD Pump is based on the same proprietary impeller suspension technology used in the HVAD Pump, with its single moving part held in place through a combination of passive-magnetic and hydrodynamic forces. Like the HVAD Pump, the MVAD Pump is designed to support the heart's full cardiac output, yet also has the capability for partial support. On September 9, 2011, pre-clinical data was presented at

26

the 19th Congress of the International Society for Rotary Blood Pumps (ISRBP), which demonstrated that the MVAD Pump attained the objectives for system performance, hemocompatability and biocompatibility in Good Laboratory Practice (“GLP”) animal studies, a precursor to human clinical trials. We are currently preparing to commence human clinical studies in the second half of 2012. The MVAD Pump is designed to be implantable by surgical techniques that are even less invasive than those required to implant the HVAD Pump.

We began generating revenue from our products in August 2008 and have incurred net losses in each year since our inception. We expect our losses to continue as we continue to develop commercial markets, expand our research and development into next generation products including the MVAD Pump and related accessories and support on-going and new clinical trial activity.

We have financed our operations primarily through the issuance of convertible notes and the issuance of shares of our common stock. Most recently, on December 15, 2010, we issued convertible notes with an aggregate principal amount of $143.75 million pursuant to the terms of an Indenture dated as of December 15, 2010. The convertible notes are senior unsecured obligations of the Company. The convertible notes bear interest at a rate of 3.5% per annum, payable semi-annually in arrears on June 15 and December 15 of each year. The convertible notes will mature on December 15, 2017, unless earlier repurchased or converted.

We are headquartered in Framingham, Massachusetts. We have operations and manufacturing facilities in Miami Lakes, Florida, a development and operations facility in Sydney, Australia and a distribution and customer service facility in Hannover, Germany.

Critical Accounting Policies and Estimates

We prepare our financial statements in accordance with accounting principles generally accepted in the United States. We are required to adopt various accounting policies and to make estimates and assumptions in preparing our financial statements that affect the reported amounts of our assets, liabilities, revenue and expenses. On an ongoing basis, we evaluate our estimates and assumptions. We base our estimates on our historical experience to the extent practicable and on various other assumptions that we believe are reasonable under the circumstances and at the time they are made. If our assumptions prove inaccurate or if our future results are not consistent with our historical experience, we may be required to make adjustments in our policies that affect our reported results. Our significant accounting policies are disclosed in Note 3 to the Consolidated Financial Statements included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2011 (“2011 Annual Report on Form 10-K”) filed with the Securities and Exchange Commission on February 27, 2012. During the six months ended June 30, 2012, there were no significant changes to any of our significant accounting policies.

Our most critical accounting policies and estimates include revenue recognition, inventory capitalization and valuation, accounting for share-based compensation, measurement of fair value, and the valuation of tax assets and liabilities. We also have other key accounting policies that are less subjective and, therefore, their application is less subject to variations that would have a material impact on our reported results of operations. There have been no material changes to our critical accounting policies and estimates from the information provided in Part II, Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations included in our 2011 Annual Report on Form 10-K.

Results of Operations

Three and six months ended June 30, 2012 and 2011

Revenue, net

In the three and six months ended June 30, 2012 and 2011, we generated revenue from commercial sales outside of the U.S. and sales in connection with our clinical trials in the U.S. The increase in revenue in 2012 is primarily due to increased market penetration outside of the U.S.

27

	Three Months Ended							Six Months Ended
	June 30,							June 30,
	2012		2011		Change			2012		2011		Change
	(in thousands)							(in thousands)
Revenue, net	$	29,053	$	20,389		42	%	$	55,398	$	38,364		44	%

In the three months ended June 30, 2012, approximately 14% of our product sales were derived in the U.S. compared to approximately 31% in the three months ended June 30, 2011. In the six months ended June 30, 2012, approximately 19% of our product sales were derived in the U.S. compared to 32% in the six months ended June 30, 2011. The percentage of our revenue generated in the U.S. decreased in the three and six months ended June 30, 2012 as compared to the same periods in 2011 primarily due to the continued expansion of our commercial efforts in Europe. Revenue from U.S. sources for the three and six months ended June 30, 2012 is lower than comparable periods in 2011 due to variability in clinical enrollment. We completed enrollment in our Destination Therapy trial in May 2012.

Our sales outside of the U.S. are made in multiple currencies, with the majority of our international revenue denominated in the Euro. In the three and six months ended June 30, 2012, our net international revenue denominated in foreign currencies increased by $6.9 million, or 55%, and $12.8 million, or 56%, respectively, compared to the three and six months ended June 30, 2011. Changes in foreign exchange rates unfavorably impacted revenue by approximately $1.9 million, or 9%, and $2.4 million, or 6%, in the three and six months ended June 30, 2012, respectively, compared to the three and six months ended June 30, 2011.

Prior to FDA approval of the HeartWare System for sale in the U.S., revenue from U.S. sources may vary from quarter to quarter as revenue from U.S. clinical trials is dependent on FDA approval of Continued Access Protocols. In March 2012, the FDA approved an Investigational Device Exemption Supplement that allowed us to enroll a fourth allotment, of 54 additional patients, in our ADVANCE bridge-to-transplant clinical trial under a Continued Access Protocol (CAP). In May 2012, we completed enrollment of our ENDURANCE destination therapy clinical trial and in July 2012 requested from the FDA approval to implant additional patients under a CAP in U.S. centers that implanted a patient in the ENDURANCE trial.

Cost of Revenue

Cost of revenue includes costs associated with manufacturing and distributing our product and consists of direct materials, labor and overhead expenses allocated to the manufacturing process. Cost of revenue totaled approximately $12.7 million and $7.9 million in the three months ended June 30, 2012 and 2011, respectively. Cost of revenue totaled approximately $23.5 million and $15.5 million in the six months ended June 30, 2012 and 2011, respectively.

Gross profit and gross margin percentage are as follows:

	Three Months Ended						Six Months Ended
	June 30,						June 30,
	2012			2011			2012			2011
	(in thousands)						(in thousands)
Gross profit	$	16,388		$	12,476		$	31,905		$	22,855
Gross margin %		56.4	%		61.2	%		57.6	%		59.6	%

28

Gross margin percentage for the three and six months ended June 30, 2012 decreased compared to the same periods in 2011 primarily due to the negative impact of currency movements upon revenue, including principally the Euro, and an increase in certain reserves including warranty obligations and obsolescence. During the three and six months ended June 30, 2012 we realized increased expense related to obsolete inventory particularly related to prior versions of our controller, a component of the HVAD system. We also experienced an increase in expired product and warranty expense.

Selling, General and Administrative

Selling, general and administrative expenses include costs associated with selling and marketing our products and the general corporate administration of the Company. These costs are primarily related to salaries and wages and related employee costs, travel, external consultants and contractors, legal and accounting fees and general infrastructure costs, and include all operating costs not associated with or otherwise classified as research and development costs or cost of revenue.

Total selling, general and administrative expenses	$	14,204	$	9,892		44	%	$	26,920	$	18,556		45	%
% of operating expenses

The increase of $4.3 million for the three months ended June 30, 2012 as compared to the three months ended June 30, 2011 was primarily a result of an increase in employee costs, including salaries and wages and related costs, of approximately $1.1 million, due to increased headcount to build our global sales and marketing and administrative functions to support expected future growth. We also experienced an increase in non-cash share-based compensation expense of $1.4 million, primarily due to a reduction in our estimated forfeiture rate. Other contributors included increased costs for consultants and contractors of $0.2 million, marketing expenses of $0.2 million and travel expenses of $0.3 million. Increased legal costs of $0.8 million associated with litigation and corporate transaction activity, including the acquisition of World Heart, were offset by the anticipated insurance recovery of $0.8 million related to the settlement of litigation discussed in Note 15 to the accompanying condensed consolidated financial statements.

The increase of $8.4 million for the six months ended June 30, 2012 as compared to the six months ended June 30, 2011 was primarily a result of an increase in employee costs, including salaries and wages and related costs, of approximately $2.8 million, due to increased headcount to build our global sales and marketing and administrative functions to support expected future growth. We also experienced an increase in non-cash share-based compensation expense of $1.8 million, primarily due to a reduction in our estimated forfeiture rate. Other contributors included increased costs for consultants and contractors of $0.6 million, marketing expenses of $0.5 million, travel expenses of $0.6 million and office expenses of $0.2 million. Increased legal costs of $1.1 million associated with litigation and corporate transaction activity, including the acquisition of World Heart, were mostly offset by the anticipated insurance recovery of $0.8 million related to the settlement of litigation discussed in Note 15 to the accompanying condensed consolidated financial statements.

We expect our selling, general and administrative expenses to continue to increase in 2012 compared to 2011 as we prepare for the launch of the HeartWare System in the United States, and continue to expand our sales and distribution capabilities as well as our administrative capabilities to support our overall corporate growth. We have and will continue to experience an increase in our employee headcount as well as an increase in costs associated with the necessary administrative infrastructure to support this expansion.

29

Research and Development

Research and development expenses are the direct and indirect costs associated with developing our products prior to commercialization and are expensed as incurred. These expenses fluctuate based on project level activity and consist primarily of salaries and wages and related employee costs of our research and development, clinical and regulatory staff, external research and development costs, and materials and expenses associated with clinical trials. Additional costs include travel, facilities and overhead allocations.

	Three Months Ended June 30,							Six Months Ended June 30,
	2012		2011		Change			2012		2011		Change
	(in thousands)							(in thousands)
Total research and development expenses	$	20,005	$	10,280		95	%	$	40,012	$	19,580		104	%
% of operating expenses

The increase of $9.7 million for the three months ended June 30, 2012 as compared to the three months ended June 30, 2011 was due to an increase in costs associated with development projects, including consumables, outside engineering, consultants and contractors, of $4.2 million, related to development projects and on-going clinical trials. We also experienced an increase in employee costs, including salaries and wages and related costs, of approximately $1.1 million related to new product development and an increase in non-cash share-based compensation of $1.0 million due to a reduction in our estimated forfeiture rate. Costs associated with our U.S. clinical trials increased by $3.2 million.

The increase of $20.4 million for the six months ended June 30, 2012 as compared to the six months ended June 30, 2011 was due to an increase in costs associated with development projects, including consumables, outside engineering, consultants and contractors, of $11.2 million, primarily related to development projects and on-going clinical trials. We also experienced an increase in employee costs, including salaries and wages and related costs, of approximately $2.9 million related to new product development and an increase in non-cash share-based compensation of $1.1 million due to a reduction in our estimated forfeiture rate. Costs associated with our U.S. clinical trials increased by $4.4 million.

We expect that research and development expenses will continue to represent a significant portion of our operating expenses for the foreseeable future related to clinical trials in the U.S. and new product development, including costs related to the development of the MVAD system.

Foreign Exchange

We generate a substantial portion of our revenue and collect receivables in foreign currencies. Fluctuations in the exchange rate of the U.S. dollar against the Euro, British Pound and Australian dollar can result in foreign currency exchange gains and losses that may significantly impact our financial results. Continued fluctuation of these exchange rates could result in financial results that are not comparable from quarter to quarter. In general, we do not currently utilize foreign currency contracts to mitigate foreign exchange gains and losses.

In the three and six months ended June 30, 2012, our net foreign exchange losses totaled approximately $2.2 million and $1.1 million, respectively, compared to net gains of approximately $0.1 million and $0.7 million in the same periods of 2011. In 2012 and 2011, the majority of our realized and unrealized foreign exchange gains and losses were experienced upon the collection of certain accounts receivable that were denominated in foreign currencies, and the translation to U.S. dollars at period end of certain balance sheet accounts, denominated in foreign currencies, primarily the Euro. We expect to continue to realize foreign exchange gains and losses for the foreseeable future as the majority of our sales denominated in foreign currencies are settled in Euros.

30

Interest Expense

Interest expense in 2012 and 2011 consists of interest incurred on the principal amount of our convertible senior notes issued in December 2010, amortization of the related discount and amortization of the portion of the deferred financing costs allocated to the debt component. The convertible senior notes bear interest at a rate of 3.5% per annum. The discount on the convertible senior notes and the deferred financing costs are being amortized to interest expense through the December 15, 2017 maturity date of the convertible senior notes using the effective interest method.

In the three months ended June 30, 2012, interest expense was approximately $2.82 million, which included $1.26 million of interest incurred on the principal amount of the convertible notes at the 3.5% coupon rate and $1.56 million of non-cash amortization of the discount and deferred financing costs. In the three months ended June 30, 2011, interest expense was approximately $2.65 million, which included $1.26 million of interest incurred on the principal amount of the convertible notes at the 3.5% coupon rate and $1.39 million of non-cash amortization of the discount and deferred financing costs.

In the six months ended June 30, 2012, interest expense was approximately $5.6 million, which included $2.51 million of interest incurred on the principal amount of the convertible notes at the 3.5% coupon rate and $3.09 million of non-cash amortization of the discount and deferred financing costs. In the six months ended June 30, 2011, interest expense was approximately $5.25 million, which included $2.51 million of interest incurred on the principal amount of the convertible notes at the 3.5% coupon rate and $2.74 million of non-cash amortization of the discount and deferred financing costs.

Investment Income, net

Investment income is primarily derived from investments and cash and short-term deposit accounts held in the U.S. The amortization of premium on our investments is also included in investment income, net. Investment income, net was approximately $0.1 million and $0.2 million in the three and six months ended June 30, 2012, compared to $0.1 million and $0.3 million in the same periods in the prior year. We have had lower cash and investments balances during 2012 and have experienced lower interest rates compared to 2011.

Income Taxes

We are subject to taxation in the United States and jurisdictions outside of the United States. These jurisdictions have different marginal tax rates. While we have incurred losses since inception, changes in issued capital and share ownership, as well as other factors, may limit our ability to utilize any net operating loss carry-forwards, and as such a 100% valuation allowance has been recorded against our net deferred tax assets.

As of June 30, 2012, we did not have earnings which would be sufficient to allow any portion of our deferred tax assets to be recorded. We intend to monitor closely whether to record a deferred tax asset as we further expand the commercialization of our products.

Liquidity and Capital Resources

As of June 30, 2012, our cash and cash equivalents were approximately $114.5 million as compared to $71.3 million at December 31, 2011.

Following is a summary of our cash flow activities:

	Six Months Ended June 30,

Cash Used in Operating Activities

For the six months ended June 30, 2012, cash used in operating activities included a net loss of approximately $41.6 million and non-cash adjustments to net loss totaling approximately $16.2 million, which primarily consisted of $10.1 million of share-based compensation, $2.9 million for the amortization of the discount on our convertible senior notes and $2.1 million of depreciation and amortization on long-lived assets. Also included in cash used in operating activities in the six months ended June 30, 2012 is approximately $6.8 million related to an increase in accounts receivable, $3.2 million for the purchase and manufacture of inventories and $1.3 million for prepaid expenses and other current assets. These amounts were partially offset by increases in trade accounts payable of $6.0 million and other current liabilities of $0.8 million.

For the six months ended June 30, 2011, cash used in operating activities included a net loss of approximately $19.5 million and non-cash adjustments to net loss totaling approximately $11.0 million, which primarily consisted of $6.4 million of share-based compensation, $2.6 million for the amortization of the discount on our convertible notes and $1.1 million of depreciation and amortization. Also included in cash used in operating activities in the six months ended June 30, 2011 is approximately $7.5 million for the purchase and manufacture of inventories, $2.2 million for prepaid expenses and $555,000 for payment of trade accounts payable. These amounts were partially offset by net collections of trade accounts receivable of $3.5 million and an increase in accrued expenses of $1.3 million.

Cash Used in Investing Activities

In the six months ended June 30, 2012, net cash provided by investing activities included $75.0 million received upon maturity (net of purchases) of available-for-sale securities, $2.9 million used to acquire property, plant and equipment and $0.8 million paid for a security deposit on a facility lease.

In the six months ended June 30, 2011, net cash used by investing activities included $55.1 million for the purchase (net of maturities in 2011) of available-for sale securities. Other investing activities in the six months ended June 30, 2011 used cash of approximately $4.9 million. These amounts were expended to acquire property, plant and equipment and for capitalized patent costs.

Cash Provided by Financing Activities

The exercise of stock options in the six months ended June 30, 2012 and 2011 resulted in cash proceeds of approximately $1.1 million and $0.6 million, respectively.

Operating Capital and Capital Expenditure Requirements

We have incurred operating losses to date and anticipate that we will continue to incur substantial net losses as we expand our sales and marketing capabilities, and develop new products. For the remainder of 2012, cash on hand is expected to primarily be used to fund our ongoing operations, including;

• Expanding our sales and marketing capabilities on a global basis, including preparing for the commercial launch in the U.S. of the HeartWare System subject to FDA approval,

• continued product development, including first human implants and clinical trials of next generation projects,

• existing and new clinical trials,

• regulatory and other compliance functions, and

• general working capital.

32

We expect to experience increased cash requirements for inventory and other working capital requirements to support continued growth.

Our convertible notes bear interest at a rate of 3.5% per annum, payable semi-annually in arrears on June 15 and December 15 of each year. During the quarter ended June 30, 2012 we paid the $2.5 million interest payment that was due on June 15, 2012. The $2.5 million interest payments that were due on June 15 and December 15, 2011 were also paid on a timely basis. Based on the outstanding principal amount of our convertible senior notes at June 30, 2012, the semi-annual interest payment due on December 15, 2012 will be approximately $2.5 million. This amount is expected to be paid from cash on hand.

We believe cash on hand and investment balances as of June 30, 2012 are sufficient to support our planned operations for at least the next twelve months.

Because of the numerous risks and uncertainties associated with the development of medical devices we are unable to estimate the exact amounts of capital outlays and operating expenditures necessary to maintain regulatory approvals, fund commercial expansion. and develop and obtain regulatory approvals for new products. Our future capital requirements will depend on many factors, including but not limited to the following:

• commercial acceptance of our products;

• costs to manufacture our products;

• expenses required to operate multiple clinical trials;

• further product research and development for next generation products and peripherals and expanding indications for our products as well as efforts to sustain and implement incremental improvements to existing products;

• expanding our sales and marketing capabilities on a global basis, including building a team to support U.S. commercialization should the FDA approve our device for marketing in the U.S.;

• broadening our infrastructure in order to meet the needs of our growing operations;

• expenses related to funding and integrating strategic investments, acquisitions and collaborative arrangements; and

• complying with the requirements related to being a public company in both the United States and Australia.

Contractual Obligations

In the six months ended June 30, 2012, there were no material changes to our contractual obligations provided in Part II, Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations included in our 2011 Annual Report on Form 10-K filed with the SEC on February 27, 2012, outside the ordinary course of business.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market risk represents the risk of changes in the value of market risk sensitive instruments caused by fluctuations in interest rates, foreign exchange rates and commodity prices. Changes in these factors could cause fluctuations in our results of operations and cash flows.

Interest Rate Risk

Our exposure to interest rate risk is currently confined to interest earnings on our cash and cash equivalents that are invested in highly liquid money market funds, short-term time deposits, short-term bank notes and short-term commercial paper. The primary objective of our investment activities is to preserve our capital to fund operations. We also seek to generate reasonable income from our investments without assuming significant risk. We do not presently use derivative financial instruments in our investment portfolio. Our cash and investments policy emphasizes liquidity and preservation of principal over other portfolio considerations.

If interest rates rise, the market value of our investment portfolio may decline, which could result in a loss if we choose or are forced to sell an investment before its scheduled maturity. We do not utilize derivative financial instruments to manage interest rate risks.

Our convertible senior notes do not bear interest rate risk as the notes were issued with a fixed interest rate of 3.5% per annum.

Foreign Currency Rate Fluctuations

We conduct business in foreign countries. For U.S. reporting purposes, we translate all assets and liabilities of our non-U.S. entities at the period-end exchange rate and revenue and expenses at the average exchange rates in effect during the periods. The net effect of these translation adjustments is shown in the accompanying condensed consolidated financial statements as a component of stockholders’ equity.

We generate a significant portion of our revenue and collect receivables in foreign currencies. Fluctuations in the exchange rate of the U.S. dollar against major foreign currencies, including the Euro, British Pound and Australian dollar, can result in foreign currency exchange gains and losses that may significantly impact our financial results. These foreign currency transaction and translation gains and losses are presented as a separate line item on our condensed consolidated statements of operations. Continued fluctuation of these exchange rates could result in financial results that are not comparable from quarter to quarter. We do not currently utilize foreign currency contracts to mitigate the gains and losses generated by the re-measurement of non-functional currency assets and liabilities but do hold cash reserves in currencies in which those reserves are anticipated to be expended.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of the Chief Executive Officer and Chief Financial Officer, carried out an evaluation required by the Securities Exchange Act of 1934, as amended (the “Exchange Act”), of the effectiveness of the design and operation of our disclosure controls and procedures, as defined in Rule 13a-15(e) of the Exchange Act, as of June 30, 2012. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of June 30, 2012, our disclosure controls and procedures were effective to provide reasonable assurance that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms and to provide reasonable assurance that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosures.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting during the fiscal quarter ended June 30, 2012, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Inherent Limitations on Controls and Procedures

Our management, including the Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent all error and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, have been detected. Thus, misstatements due to error or fraud may occur and not be detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of controls.

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

Except as described in Note 15 to the accompanying condensed consolidated financial statements, the Company is not a party to any material legal proceedings at the date of filing of the Quarterly Report on Form 10-Q.

ITEM 1A. RISK FACTORS

In addition to the information set forth in this report you should carefully consider the risk factors described in Part I, Item 1A. “Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2011 filed with the SEC on February 27, 2012.

The following risk factor reflects a material addition to the Risk Factors set forth in our 2011 Annual Report on Form 10-K.

Global market and economic conditions may exacerbate certain risks affecting our business.

International markets, especially Europe, represent a major part of our present business. Approximately 86% of our second quarter 2012 revenues were derived from international sales and much of our marketing efforts are focused on European countries. Although not materially impacted to date, our accounts receivable in certain European countries may be subject to significant payment delays due to government funding and reimbursement practices or limited financial flexibility of our distributors. European governments have announced or implemented austerity measures to constrain the overall level of government expenditures, which may include reforming health care coverage and reducing health care costs. These measures will continue to exert pressure on our customers and may impact their ability to pay for product on a timely basis or to maintain their current purchasing patterns. These adverse market and economic conditions could reduce our product sales and revenue, result in additional allowances, or reduce credit sales to our distribution network.
