1. Description of Business and Summary of Significant Accounting Policies

Fusion-io, Inc. (the “Company” or “Fusion-io”) provides an enterprise storage memory platform, based on the Company’s ioMemory technology with VSL storage virtualization software, automated data-tiering and virtualization caching software, datacenter management software, ION Data Accelerator software, and storage memory programming software. The Company was originally incorporated in the state of Nevada in December 2005 and in June 2010 was reincorporated in the state of Delaware as Fusion-io, Inc. The Company sells its products and services through its global direct sales force, original equipment manufacturers (“OEMs”), and other channel partners.

Basis of Presentation

The accompanying condensed consolidated balance sheets and the condensed consolidated statements of operations, comprehensive income, and cash flows are unaudited. These unaudited interim condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) on the same basis as the audited consolidated financial statements and, in the opinion of management, reflect all adjustments (all of which are considered of a normal recurring nature) considered necessary to present fairly the Company’s financial position, results of operations, and cash flows. The results of operations for the three months ended September 30, 2012 are not necessarily indicative of the results that may be expected for the full fiscal year ending June 30, 2013 or any other period.

These unaudited interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended June 30, 2012 (the “2012 Annual Report”) filed with the Securities and Exchange Commission (the “SEC”).

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

Segment and Geographic Information

Operating segments are defined in accounting standards as components of an enterprise about which separate financial information is available and is regularly evaluated by management, namely the chief operating decision maker of an organization, in order to make operating and resource allocation decisions. The Company has concluded it operates in one business segment, which is the development, marketing, and sale of storage memory platforms. Substantially all of the Company’s revenue for all periods presented in the accompanying condensed consolidated statements of operations has been from sales of the ioDrive product lines and related customer support services. The Company’s headquarters and most of its operations are located in the United States; however, it conducts sales activities through sales offices in Europe and Asia. Revenue recognized from sales with a ship-to location outside of the United States was 29% and 38% of revenue for the three months ended September 30, 2011 and 2012, respectively. Revenue recognized from sales to customers with a ship-to address in Puerto Rico was 11% of revenue for the three months ended September 30, 2011 and revenue recognized from sales to customers with a ship-to address in Germany was 19% of revenue for the three months ended September 30, 2012. No other country outside of the United States accounted for 10% or more of revenue for all periods presented. Long-lived assets located outside of the United States were not material for all periods for which a condensed consolidated balance sheet is presented.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. On an on-going basis, the Company evaluates its significant estimates, including those related to revenue recognition, sales returns, accounting for business combinations and impairment of long-lived and intangible assets including goodwill, determination of fair value of stock options, valuation of inventory, product warranty, and income taxes. The Company also uses estimates in determining the useful lives of property and equipment and intangible assets and provisions for doubtful accounts. Actual results could differ from those estimates.

Significant Customers

Customers that accounted for 10% or more of the Company’s revenue represented 68% and 70% of revenue for the three months ended September 30, 2011 and 2012, respectively. As a result of the concentration of the Company’s customers, and typically a small number of large purchases by these customers, revenue, gross margin, and operating results may fluctuate significantly from period to period.

Product Warranty

The Company provides its customers a standard limited product warranty of up to five years. The standard warranty requires the Company to repair or replace defective products at no cost to the customer during such warranty period. The Company estimates the costs that may be incurred under its standard limited warranty and records a liability in the amount of such costs at the time product sales are recognized. Factors that affect the Company’s warranty liability include the number of installed units, identified warranty issues, historical experience, and management’s judgment regarding anticipated rates of warranty claims and cost per claim. The Company assesses the adequacy of its recorded warranty liability each period and makes adjustments to the liability as necessary based on actual experience.

The following table presents the changes in the product warranty liability (in thousands):

	Total
Balance at June 30, 2012	$	2,825
Warranty costs accrued		359
Warranty claims		(522	)
Balance at September 30, 2012	$	2,662

Warranty costs accrued includes amounts accrued for products at the time of shipment, adjustments for changes in estimated costs for warranties on products shipped in the period, and changes in estimated costs for warranties on products shipped in prior periods. It is not practicable to determine the amounts applicable to each of these components.

Net Income Per Share

Basic net income per share is computed using the weighted-average number of common shares outstanding during the period, less weighted-average common shares subject to repurchase. Diluted net income per share is computed using the weighted-average number of common shares outstanding and potentially dilutive common shares outstanding during the period that have a dilutive effect on net income per share. Potentially dilutive common shares result from the assumed exercise of outstanding stock options, common stock warrants, restricted stock awards, restricted stock units, and the assumed vesting of outstanding restricted stock subject to vesting provisions. In a net loss position, diluted net loss per share is computed using only the weighted-average number of common shares outstanding during the period, less weighted-average common shares subject to repurchase, as any additional common shares would be anti-dilutive.

The following table presents the reconciliation of the numerator and denominator used in the calculation of basic and diluted net income per share (in thousands):

	Three Months Ended September 30,
	2011			2012
Numerator:
Net income	$	7,189		$	3,933
Denominator:
Weighted-average common shares outstanding		82,232			94,432
Less weighted-average common shares outstanding subject to repurchase		(224	)		(211	)
Weighted-average shares, basic		82,008			94,221
Effect of dilutive securities		21,446			14,204
Weighted-average shares, diluted		103,454			108,425

The computation of diluted net income per common share for the three months ended September 30, 2011 and 2012 excluded common stock equivalents of 3,803,000 and 6,504,577, respectively, as their impact was anti-dilutive.

Recently Issued and Adopted Accounting Pronouncements

In June 2011, the FASB issued new guidance which improves the comparability, consistency, and transparency of financial reporting and increases the prominence of items reported in other comprehensive income (“OCI”) by eliminating the option to present

- 6 -

FUSION-IO, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(unaudited)

components of OCI as part of the statement of changes in stockholders’ equity. The amendments in this standard require that all nonowner changes in stockholders’ equity be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements. Subsequently in December 2011, the FASB issued additional guidance, which indefinitely defers the requirement to present on the face of the financial statements reclassification adjustments for items that are reclassified from OCI to net income in the statement where the components of net income and the components of OCI are presented. The amendments in these standards do not change the items that must be reported in OCI, when an item of OCI must be reclassified to net income, or change the option for an entity to present components. The Company adopted this guidance retrospectively in the first quarter of fiscal year 2013. The adoption of this guidance did not have an impact on the Company’s results of operations, financial position, or cash flows as it related only to financial statement presentation.

3. Fair Value Measurements

Assets Measured and Recorded at Fair Value on a Recurring Basis

The Company measures and records certain financial assets at fair value on a recurring basis. Fair value is based on the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.

The Company’s financial instruments that are measured at fair value on a recurring basis consist of money market funds. The following three levels of inputs are used to measure the fair value of financial instruments:

Level 1:	Quoted prices in active markets for identical assets or liabilities. The Company classifies its money market funds as Level 1 instruments as they are traded in active markets with sufficient volume and frequency of transactions.
Level 2:	Observable prices that are based on inputs not quoted on active markets, but corroborated by market data.
Level 3:	Unobservable inputs are used when little or no market data is available.

The fair value of the Company’s money market funds was as follows (in thousands):

	Fair Value Measurements at June 30, 2012
Description	Level 1		Level 2		Level 3		Total
Cash equivalents:
Money market funds	$	266,944	$	—	$	—	$	266,944

Description	Level 1		Level 2		Level 3		Total
Cash equivalents:
Money market funds	$	267,048	$	—	$	—	$	267,048

Fair Value of Other Financial Instruments

The carrying amounts of the Company’s accounts receivable, accounts payable, accrued liabilities, and other liabilities approximate their fair values due to their short maturities.

4. Acquisitions

On August 11, 2011, the Company acquired 100% of the stock of IO Turbine, Inc. (“IO Turbine”) pursuant to the Agreement and Plan of Reorganization (the “Merger Agreement”) dated August 4, 2011. IO Turbine was a provider of caching solutions for virtual environments, based in San Jose, California. Accordingly, the assets, liabilities, and operating results of IO Turbine are reflected in the Company’s condensed consolidated financial statements following the date of acquisition. The fair value of the aggregate purchase price was approximately $65,568,000, which consisted of (1) cash of approximately $21,199,000, (2) approximately $43,485,000 in common stock valued at $28.40 per share, the closing sale price of the Company’s common stock on the closing date of the acquisition, and (3) approximately $884,000 in assumed stock options attributable to pre-acquisition service. In addition, subsequent to the acquisition, the Company will recognize up to approximately $26,421,000 of stock-based compensation expense related to the fair value of assumed restricted stock awards (“RSAs”) and stock options, of which approximately $3,795,000 were expensed immediately in connection with the acceleration of vesting of certain restricted stock awards and the remainder will be recognized over the underlying future service period of the assumed stock awards and stock options. At the time of acquisition, IO Turbine stockholders holding RSAs had the option to receive cash and/or shares of the Company’s common stock for their unvested RSAs based on a fixed value determined at the acquisition date. As a result, the Company: (1) issued approximately 414,000 shares of its common stock that remain subject to forfeiture based on the original vesting schedule applicable to such awards and (2) will pay up to approximately $4,631,000 in cash in accordance with the original vesting schedule applicable to such awards. Of this total cash amount, approximately $2,407,000 had been paid through September 30, 2012.

For the three months ended September 30, 2011 and 2012, operating expenses associated with IO Turbine were approximately $6,443,000 and $3,056,000, respectively, of which approximately $5,261,000 and $2,269,000, respectively, related to stock-based compensation expense.

Unaudited pro forma financial information

The following unaudited pro forma financial information is based on the combined historical financial statements of the Company and IO Turbine after giving effect to the Company’s acquisition of IO Turbine as if it had occurred as of July 1, 2010 and includes pro forma adjustments related to the amortization of acquired intangible assets, stock-based compensation expense, and depreciation expense (in thousands, except per share data):

Revenue	$	74,385	$	118,115
Net income from operations		412		8,449
Net income		2,934		3,933
Net income per share, basic	$	0.04	$	0.04

The amounts in the table above do not include non-recurring expense of approximately $3,795,000 related to the acceleration of vesting on certain stock-based awards that was recorded by the Company as stock-based compensation expense in the three months ended September 30, 2011.

	$	7,508

6. Long-term Obligations

Loan and Security Agreement

In September 2010, the Company amended and restated its loan and security agreement (the “Revolving Line of Credit”) with a financial institution. The Revolving Line of Credit allows the Company to borrow up to a limit of $25,000,000. A sublimit of $6,000,000 for letters of credit, certain cash management services, and foreign exchange forward contracts applied until May 2012. The total balance of letters of credit outstanding at September 30, 2012 was $3,183,000, which reduces the amount the Company has available to borrow under the Revolving Line of Credit. Prior to May 2012, borrowings under the Revolving Line of Credit would have accrued interest at a floating per annum rate equal to one-half of one percentage point (0.50%) above the prime rate as published in the Wall Street Journal. An unused commitment fee equal to 0.375% of the difference between the $25,000,000 limit and the average daily balance of borrowings outstanding each quarter was due on the last day of such quarter. Prior to May 2012, the Revolving Line of Credit was secured by substantially all of the Company’s assets. The Company can make advances against the Revolving Line of Credit until its maturity date, at which time all unpaid principal and interest shall be due and payable.

In August 2011, the Company entered into an amendment to the Revolving Line of Credit which provided for the consent of the financial institution with respect to the acquisition of IO Turbine and certain amendments to provide the Company with further flexibility to consummate mergers and acquisitions permitted under the Revolving Line of Credit.

In May 2012, the Company entered into a second amendment to the Revolving Line of Credit. Pursuant to this amendment, the pricing on revolving line of credit was amended such that borrowings under the Revolving Line of Credit accrue interest at a per annum rate equal to, at the Company’s option, a floating per annum rate equal to the prime rate as published in the Wall Street Journal, or the LIBOR rate (based on 1, 2, 3 or 6-month interest periods) plus a margin equal to two percent (2.00%) per annum. This amendment further provides for, among other things, (i) the reduction of the quarterly unused commitment fee to an amount equal to one-quarter of one percent (0.25%) per annum of the difference between the $25,000,000 loan commitment and the average daily balance of borrowings outstanding on the last day of each quarter, (ii) the removal of the borrowing base formula and the sublimit restricting the issuance of letters of credit, cash management services and foreign exchange forward contracts, and (iii) the release of the financial institution’s security interest in all of the Company’s assets.

Under the terms of the Revolving Line of Credit, the Company is required to maintain the following minimum financial covenants on a consolidated basis:

• A ratio of current assets to current liabilities plus, without duplication, any of the Company’s obligations to the financial institution, of at least 1.25 to 1.00.

• A tangible net worth of at least $25,000,000, plus 25% of the net proceeds the Company received from the sale or issuance of its equity or subordinated debt, such increase to be measured as of the last day of the quarter in which the Company received such proceeds.

In September 2012, the Company entered into a third amendment to the Revolving Line of Credit. Pursuant to this amendment, the maturity date of the Revolving Line of Credit was extended to December 2012.

As of September 30, 2012, no borrowings were outstanding under the Revolving Line of Credit and the Company was in compliance with all covenants.

7. Income Taxes

        In order to determine the quarterly provision for income taxes, the Company considers the estimated annual effective tax rate, which is based on expected annual income and statutory tax rates in the various jurisdictions in which the Company operates. To the extent that application of the estimated annual effective tax rate is not representative of the quarterly portion of actual tax expense expected to be recorded for the year, the Company determines the quarterly provision for income taxes based on actual year-to-date income. Certain significant or unusual items are separately recognized in the quarter during which they occur and can be a source of variability in the effective tax rates from quarter to quarter.

The components of the Company income tax expense or benefit include state income taxes, foreign income taxes, U.S. federal alternative minimum tax, and effects of stock-based awards. Income tax benefit was approximately $1,726,000 and income tax expense was approximately $4,571,000 for the three months ended September 30, 2011 and 2012, respectively, or approximately a benefit of 32% and an expense of 54% of income before income taxes, respectively. The Company’s effective tax rate for the three months ended September 30, 2012 is higher when compared to the same period in the prior year primarily due to the income tax benefit recorded in the prior year as a result of a valuation allowance reversal related to deferred tax liabilities generated from the acquisition of IO Turbine. In addition, the prior year taxable income was substantially offset by net operating losses which are no longer available to offset income tax expense in the current year. The effective tax rate for the three months ended September 30, 2012 differs from the U.S. federal statutory rate of 35% primarily due to the Company’s full valuation allowance against its net deferred tax assets, the tax effect of stock-based awards, as well as foreign and state tax expense.

The Company files U.S., state, and foreign income tax returns in jurisdictions with various statutes of limitations. The Company’s consolidated federal tax return and any significant state or foreign tax returns are not currently under examination.

The Company is subject to income taxes in various U.S. and foreign jurisdictions and to continual examination by tax authorities. Significant judgment is required in evaluating the Company’s uncertain tax positions and determining its provision for income taxes. During the three months ended September 30, 2012, the aggregate change in the total gross amount of unrecognized tax benefits was as follows (in thousands):

	Total
Balance at June 30, 2012	$	2,709
Decrease of unrecognized tax benefits taken in prior years		(39	)
Increase in unrecognized tax benefits related to current year		405
Balance at September 30, 2012	$	3,075

The Company recognizes interest and penalties related to uncertain tax positions as a component of income tax expense. The Company did not incur any material interest or penalties related to income taxes in any of the periods presented. The total amount of unrecognized tax benefits that, if recognized, would affect the effective tax rate is approximately $715,000. The Company does not anticipate any significant change of its uncertain tax positions within fiscal year 2013, and the Company does not anticipate any events which could cause a change to these uncertainties.

As of September 30, 2012, the Company had federal net operating loss carryforwards of $204,655,000, of which $201,520,000 relate to stock option deductions claimed for tax purposes greater than the deductions claimed for book purposes. As of September 30, 2012, the Company had state net operating loss carryforwards of $176,306,000, of which $161,996,000 relate to stock option deductions claimed for tax purposes greater than the deductions claimed for book purposes. Additionally, the Company had federal research and development tax credit carryforwards of $2,543,000, of which $2,492,000 relate to stock option deductions claimed for tax purposes greater than the deductions claimed for book purposes. The Company had state research and development tax credit carryforwards of $2,412,000, of which $537,000 related to stock option deductions claimed for tax purposes greater than the deductions claimed for book purposes. In the future, the Company intends to utilize any carryforwards available to reduce its tax payments.

The Company recorded directly to equity a tax benefit for the three months ended September 30, 2012 of approximately $4,385,000 related to certain tax deductions for stock-based awards.

8. Stockholders’ Equity

Equity Incentive Plans

On July 1, 2012, the number of authorized shares of common stock available for issuance under the 2011 Equity Incentive Plan (the “2011 Plan”) was increased by 4,681,423 shares in accordance with the provisions of the 2011 Plan. At September 30, 2012, a total of 11,409,895 shares of common stock were available for grant under the Company’s equity incentive plans.

Stock option activity for all the Equity Incentive Plans for the three months ended September 30, 2012 was as follows:

	Number of Shares Subject to Outstanding Options			Weighted- Average Exercise Price Per Share		Weighted- Average Contractual Term (in Years)		Aggregate Intrinsic Value (1)
								(in thousands)
Outstanding as of June 30, 2012		19,885,406		$	5.21
Granted		645,050			28.86
Exercised		(1,688,246	)		2.53

Outstanding as of September 30, 2012		18,794,986		$	6.23		7.86	$	451,803
Vested and expected to vest as of September 30, 2012		17,084,497		$	5.82		7.79	$	417,647
Vested and exercisable as of September 30, 2012		7,007,421		$	2.84		7.31	$	192,205

(1) The aggregate intrinsic value is equal to the difference between the exercise price of the underlying stock option awards and the fair value of the Company’s common stock as of September 30, 2012.

Employee Stock Options

Additional per share information related to stock options granted to employees was as follows:

	Three Months Ended September 30,
	2011		2012
Weighted-average grant date fair value — granted	$	10.86	$	15.42
Weighted-average grant date fair value — assumed in connection with the acquisition of IO Turbine		27.31		—
Weighted-average grant date fair value — forfeited		9.08		11.06

The aggregate intrinsic value of stock options exercised during the three months ended September 30, 2011 and 2012 was approximately $2,086,000 and $41,576,000, respectively, which reflected the difference between the exercise prices of the underlying stock option awards and the fair value of the Company’s common stock on the date of exercise.

The Company recorded stock-based compensation expense related to employee stock options of approximately $2,443,000 and $5,093,000 for the three months ended September 30, 2011 and 2012, respectively. As of September 30, 2012, there was approximately $53,569,000 of total unrecognized compensation expense related to unvested stock options, which is expected to be recognized over a weighted-average service period of 2.8 years.

The Company estimates the fair value of stock options granted to employees using the Black-Scholes-Merton pricing model and a single option award approach, which requires the input of several highly subjective and complex assumptions. The risk-free interest rate for the expected term of the option is based on the yield available on United States Treasury Zero Coupon issues with an equivalent expected term. The expected option term used in the Black-Scholes-Merton pricing model is calculated using the simplified method. The simplified method defines the expected term as the average of the option’s contractual term and the option’s weighted-average vesting period. The Company utilizes this method as it has limited historical stock option data that is sufficient to derive a reasonable estimate of the expected stock option term. The computation of estimated expected volatility is based on the volatility of comparable companies from a representative peer group selected based on industry data.

The following table presents the assumptions used in the Black-Scholes-Merton pricing model related to employee stock options:

	Three Months Ended September 30,
	2011	2012
Expected volatility	59.1–59.9%	61.4–63.1%
Expected term (in years)	5.2–6.6	4.5–5.4
Risk-free interest rate	1.2–2.0%	0.6–0.7%
Expected dividends	—	—

Non-employee Stock Options

The Company from time to time grants options to purchase common stock to non-employees for advisory and consulting services. The Company estimates the fair value of these stock options using the Black-Scholes-Merton option pricing formula at each balance sheet date and records expense ratably over the vesting period of each stock option award. The Company recorded stock-based compensation expense related to these non-employee stock options of approximately $1,742,000 and $2,748,000 for the three months ended September 30, 2011 and 2012, respectively.

The following table presents the assumptions used in the Black-Scholes-Merton pricing model related to non-employee stock options:

	Three Months Ended September 30,
	2011	2012
Expected volatility	59.7–61.9%	61.2–61.8%
Expected term (in years)	7.1–9.7	6.1–8.7
Risk-free interest rate	1.9–2.4%	1.3–1.7%
Expected dividends	—	—

Restricted Stock Units and Restricted Stock Awards

The following table summarizes activity during the three months ended September 30, 2012 related to restricted stock units (“RSUs”) and RSAs:

	Number of Shares			Weighted-Average Grant-Date Fair Value
Unvested RSUs and RSAs at June 30, 2012		1,957,566		$	24.17
Granted		860,310			27.15
Vested		(169,229	)		23.94
Forfeited		(4,965	)		28.40
Cancelled		(19,351	)		24.25
Unvested RSUs and RSAs at September 30, 2012		2,624,331		$	25.15

The Company recorded stock-based compensation expense related to RSUs and RSAs of approximately $5,270,000 and $5,344,000 for the three months ended September 30, 2011 and 2012, respectively. Of the stock-based compensation expense recognized during the three months ended September 30, 2011, approximately $3,795,000 was due to accelerated vesting of certain RSAs assumed in connection with the IO Turbine acquisition, of which, approximately $793,000 related to awards that were settled in cash at the time of acquisition. At September 30, 2012, there was approximately $60,812,000 of total unrecognized compensation cost related to unvested RSUs and RSAs. This unrecognized compensation cost is equal to the fair value of RSUs and RSAs expected to vest and will be recognized over a weighted-average period of 3.4 years.

Repurchases of Vested Restricted Stock Units

The Company is required to withhold minimum statutory taxes related to the vesting of RSUs, including the forfeiting of a portion of the newly vested award that has a current value equal to the withholding obligation. The Company is then required to remit the amount of taxes owed by the employee to the appropriate taxing authority. As a result of such forfeitures, during the three months ended September 30, 2012, the Company effectively repurchased a total of 43,392 shares of common stock related to employee tax withholding obligations. The Company has recorded approximately $1,055,000 as a financing activity for these forfeitures in the condensed consolidated statement of cash flows for the three months ended September 30, 2012. There were no repurchases of vested restricted stock units during the three months ended September 30, 2011.

Employee Stock Purchase Plan

The Company recorded stock-based compensation expense related to its 2011 Employee Stock Purchase Plan (“ESPP”) of approximately $321,000 and $704,000 for the three months ended September 30, 2011 and 2012, respectively. On July 1, 2012, the number of authorized shares available for issuance under the ESPP was increased by 936,284 shares in accordance with the provisions of the ESPP. During the three months ended September 30, 2012, the Company issued 158,241 shares of common stock under the ESPP. At September 30, 2012, a total of 1,129,105 shares of common stock were reserved for future issuance under the ESPP.

9. Commitments and Contingencies

Letters of Credit

As of June 30, 2012 and September 30, 2012, the Company had a total of $3,183,000 in letters of credit outstanding with a financial institution. These outstanding letters of credit have been issued for purposes of securing the Company’s obligations under facility leases.

Leases

Future minimum lease payments under non-cancelable operating leases were as follows (in thousands):

Fiscal Year Ended June 30,	Operating Leases
Remaining 2013	$	4,405
2014		5,618
2015		6,015
2016		6,150
2017		6,228
Thereafter		23,844
Total	$	52,260

Operating lease payments primarily relate to the Company’s leases of office space with various expiration dates through 2021. The terms of these leases often include periods of free rent, or rent holidays, and increasing rental rates over time. The Company recognizes rent expense on a straight-line basis over the lease period and has accrued for rent expense recorded but not paid.

The Company also leases certain equipment under operating leases that expire at various dates through 2016. These equipment leases typically include provisions that allow the Company at the end of the initial lease term to renew the lease, purchase the underlying equipment at the then fair market value, or return the equipment to the lessor.

Rent expense was $982,000 and $1,741,000 for the three months ended September 30, 2011 and 2012, respectively.

Purchase Commitments

In May 2012, the Company entered into a minimum purchase commitment for raw materials inventory that ends in June 2013 and provides for a termination fee based on a percentage of the amount of raw materials inventory not taken under the commitment. As of September 30, 2012, approximately $21,545,000 remained outstanding under this commitment.

Indemnification

The Company has agreed to indemnify its officers and directors for certain events or occurrences, while the officer or director is or was serving at the Company’s request in such capacity. The maximum amount of potential future indemnification is unlimited; however, the Company has a director and officer insurance policy that provides corporate reimbursement coverage that limits its exposure and enables it to recover a portion of any future amounts paid. The Company is unable to reasonably estimate the maximum amount that could be payable under these arrangements since these obligations are not capped but are conditional to the unique facts and circumstances involved. Accordingly, the Company has no liabilities recorded for these agreements as of June 30, 2012 and September 30, 2012.

Many of the Company’s agreements with channel partners and customers generally include certain provisions for indemnifying the channel partners and customers against liabilities if the Company’s products infringe a third party’s intellectual property rights. To date, the Company has not incurred any material costs as a result of such indemnification provisions and has not accrued any liabilities related to such obligations in the condensed consolidated financial statements.

Employee Agreements

The Company has various agreements with selected employees pursuant to which if their employment is terminated by the Company without cause or by the employees for good reason, or following a change of control of the Company, the employees are entitled to receive certain benefits, including severance payments, accelerated vesting of stock and stock options, and certain insurance benefits.

Legal Matters

The Company is subject to legal proceedings and claims arising in the ordinary course of business, including claims of alleged infringement of third-party intellectual property rights. With respect to certain of these matters, the Company’s third-party suppliers have agreed to indemnify and defend the Company.

On September 7, 2011, Solid State Storage Solutions, Inc. filed a lawsuit in U.S. District Court for the Eastern District of Texas against the Company and eight other companies. The complaint alleges that the Company’s products infringe U.S. Patent Nos. 6,701,471; 7,234,087; 7,721,165; 6,370,059; 7,366,016; 7,746,697; 7,616,485; 6,341,085; 6,567,334; 6,347,051; 7,064,995; and 7,327,624. The complaint seeks both damages and a permanent injunction against the Company. The Company has limited information about the specific infringement allegations, but based on its preliminary investigation of the patents identified in the complaint, the Company does not believe that its products infringe any valid or enforceable claim of these patents. The Court has set a schedule calling for a patent claim construction hearing on January 9, 2013, and a trial commencing on July 1, 2013.

No amount has been accrued or disclosed as of September 30, 2012, as the Company has determined that an unfavorable resolution is either not currently probable or that an amount or relevant range is not reasonably estimable. However, litigation is inherently unpredictable and it is possible that a loss may occur related to the aforementioned lawsuit. Any unfavorable resolution of any of these matters could materially affect the Company’s consolidated financial position, cash flows, or results of operations. All legal costs associated with litigation are expensed as incurred.

Overview

We provide Enterprise datacenter, Hyperscale, and Workstation solutions that accelerate databases, virtualization, cloud computing, big data, information systems, and the applications that help drive business from the smallest e-tailers to some of the world’s largest data centers, social media leaders, and Fortune Global 500 businesses. Our integrated hardware and software platform enables the acceleration of data away from legacy architectures and specialized hardware. This core technology leverages flash memory to significantly increase datacenter and computer-based information system efficiency, with enterprise grade performance, reliability, availability, and manageability.

We were incorporated in December 2005, and we initially focused on the engineering and development of our platform. We have experienced significant growth with revenue increasing from $74.4 million in the three months ended September 30, 2011 to $118.1 million in the three months ended September 30, 2012. Our headcount increased from 499 employees as of September 30, 2011 to 733 employees as of September 30, 2012.

We sell our products through our global direct sales force, OEMs, including Cisco, Dell, HP, and IBM, and other channel partners. Some of our OEMs and channel partners integrate our platform into their own proprietary product offerings. Our primary sales office is located in San Jose, California, and we also have additional sales presence in North America, Europe, and Asia.

Large purchases by a limited number of customers have accounted for a substantial majority of our revenue, and the composition of the group of our largest customers changes from period to period. Some of our customers make concentrated purchases to complete or upgrade specific large-scale data storage installations. These concentrated purchases are short-term in nature and are typically made on a purchase order basis rather than pursuant to long-term contracts. During the three months ended September 30, 2011 and 2012, sales to the 10 largest customers in each period, including the applicable OEMs, accounted for approximately 94% and 91% of revenue, respectively. Apple, through a reseller, our OEM customer HP, and our direct customer Facebook, each accounted for 46%, 22%, and less than 10% of our revenue, respectively, during the three months ended September 30, 2011, and 28%, 14%, and 28% of our revenue, respectively, during the three months ended September 30, 2012. We expect that sales to a limited number of customers will continue to contribute materially to our revenue for the foreseeable future.

We anticipate that sales through OEMs and other channel partners will continue to constitute a substantial portion of our future revenue. In some cases, our products must be designed or qualified into the OEM’s products. If that fails to occur for a given product line of an OEM, we would likely be unable to sell our products to that OEM during the life cycle of that product, which would adversely affect our revenue. We expect that as we continue to expand our global presence and business overseas, we will increasingly depend on our OEM relationships in such markets.

We believe that extending our platform differentiation through software innovation will be critical to achieving broader market acceptance along with maintaining or increasing our gross margins. In this regard, our ioTurbine virtualization software, directCache data-tiering software, ION Data Accelerator software, ioSphere platform management software, and storage memory programming software allow Integrated Software Vendors to develop, integrate, and add significant value to applications using our platforms. We intend to continue adding software functionality to differentiate our products. The next generation VSL 3.0 virtualization software and hardware platform is in full production. We continue to devote the majority of our research and development resources to software development, and if we are unable to successfully develop or acquire, and then market and sell additional software functionality, our ability to increase our revenue and gross margins could be adversely affected.

Our ioMemory technology forms the basis of our hardware offering and is designed as a portfolio of upgradeable design modules, enabling faster time-to-market and increased extensibility, and it provides server-based storage memory, low access latency, field upgradeability, deep error correction, self-healing protection and native PCI Express connectivity. Our second generation ioMemory technology supports the latest NAND geometries, significantly increases performance and capacity, improves reliability while retaining the ability to build storage systems of varying capacity, performance, and form factors. At the heart of the ioMemory technology is our proprietary field programmable data-path controller. It connects a large array of non-volatile memory chips natively

- 17 -

to the server’s PCI-Express 1.0 or 2.0 peripheral bus, and addresses the reliability issues of non-volatile memory with our Adaptive Flashback Protection advanced chip-level fault tolerance technology, which is capable of restoring, correcting, and resurrecting lost data in the Flash-based storage sub-system.

Our portfolio of storage memory products incorporates our ioMemory based hardware subsystems and related VSL and caching software into our family of ioDrive, ioDrive2, ioCache, and ioFX enterprise grade products. Our ioDrive, ioDrive2, ioCache, and ioFX products work in conjunction or are integrated with our ioTurbine virtualization caching software, directCache data-tiering software, and ION Data Accelerator software.

We outsource manufacturing of our hardware products using a limited number of contract manufacturers. We procure a majority of the components used in our products directly from third-party vendors and have them delivered to our contract manufacturers for manufacturing and assembly. Once our contract manufacturers perform sub-assembly and assembly quality tests, they are assembled to our specified configurations. We perform final manufacturing assurance tests, labeling, final configuration, including a final firmware installation and shipment to our customers.

As a consequence of the rapidly evolving nature of our business and our limited operating history, we believe that period-to-period comparisons of revenue and other operating results, including gross margin and operating expenses as a percentage of our revenue, are not necessarily meaningful and should not be relied upon as indications of future performance. Although we have experienced significant percentage growth in our revenue, we do not believe that our historical growth rates are likely to be sustainable or indicative of future growth.

Components of Condensed Consolidated Statements of Operations

Revenue

We derive revenue primarily from the sale of our storage memory products and support services. We sell our storage memory platforms and software through our global direct sales force, OEMs, and other channel partners. We provide our support services pursuant to support contracts, which involve hardware support, software support, and software upgrades on a when-and-if available basis for a period of one to five years. We recorded revenue from support services of $2.1 million and $7.5 million for the three months ended September 30, 2011 and 2012, respectively. For the periods presented, our software revenue was not significant to our condensed consolidated statements of operations.

Cost of Revenue

Cost of revenue consists primarily of material costs including amounts paid to our suppliers and contract manufacturers for hardware components and assembly of those components into our products. The largest portion of our cost of revenue consists of the cost of non-volatile memory components. Given the commodity nature of memory components, neither we nor our contract manufacturers generally enter into long-term supply contracts for our product components, which can cause our cost of revenue to fluctuate. Cost of revenue is recorded when the related product revenue is recognized. Cost of revenue also includes costs related to allocated personnel expenses related to customer support, warranty costs, costs of shipping, manufacturing operations, and carrying value adjustments recorded for excess and obsolete inventory.

Operating Expenses

The largest component of our operating expenses is personnel costs, consisting of salaries, benefits, and incentive compensation for our employees, which includes stock-based compensation.

Sales and Marketing

Sales and marketing expenses consist primarily of personnel costs, incentive compensation, marketing programs, travel-related costs, consulting expenses associated with sales and marketing activities, and facilities-related costs.

Research and Development

Research and development expenses consist primarily of personnel costs, prototype expenses, amortization of an intangible asset, consulting services, depreciation associated with research and development equipment, and facilities-related costs. We expense research and development costs as incurred.

General and Administrative

General and administrative expenses consist primarily of personnel costs, legal expenses, consulting and professional services, audit costs, and facility-related expenses for our executive, finance, human resources, information technology, and legal organizations.

Other income (expense), net

Other income (expense), net consists of changes in the fair value of a derivative related to a repurchase of our common stock, interest expense, interest income, realized gains and losses from investments, and transactional foreign currency gains and losses.

Trends in Our Business

Gross Margin

We anticipate our gross margin will slightly decrease due to product mix and balancing driving market adoption with gross margin.

Sales and Marketing

We plan to continue to invest in sales by increasing our sales headcount. Our sales personnel are typically not immediately productive and therefore the increase in sales and marketing expense when we add new sales representatives is not immediately offset by increased revenue and may not result in increased revenue over the long-term. The timing of our hiring of new sales personnel and the rate at which they generate incremental revenue could therefore affect our future period-to-period financial performance. We expect sales and marketing expenses to increase in absolute dollars and increase as a percentage of revenue as we expect to continue hiring new sales representatives. We also expect to expand marketing activities to drive sales opportunities and brand awareness.

Research and Development

We expect to continue to devote substantial resources to the development of our products including the development of new products. We believe that these investments are necessary to maintain and improve our competitive position. We expect research and development expenses to increase in absolute dollars and increase as a percentage of revenue as we expect to continue to invest in additional engineering personnel and infrastructure required to support the development of new products and to enhance existing products.

General and Administrative

While we expect personnel costs, including stock-based compensation expense for employees and non-employees, to be the primary component of general and administrative expenses, we also expect to continue to incur significant legal and accounting costs related to compliance with rules and regulations implemented by the SEC. We expect that general and administrative expenses will continue to increase in absolute dollars and as a percentage of revenue primarily due to general growth of the business, infrastructure costs to support our international growth, and in legal costs related to intellectual property.

	2011		2012		$		%
Sales and marketing	$	17,477	$	25,020	$	7,543		43	%

Sales and marketing expenses increased $7.5 million from the three months ended September 30, 2011 compared to the three months ended September 30, 2012, primarily due to an increase in sales and marketing personnel, as we hired additional employees to focus on acquiring new customers and expanding our business. This increase in headcount resulted in a $5.2 million increase in personnel-related costs, including a $1.1 million increase in sales commissions. The largest portion of the remaining increase was due to a $0.6 million increase in tradeshow-related costs.

Income tax benefit (expense)	$	1,726	$	(4,571	)	$	(6,297	)		(365	)%

Income tax benefit (expense) changed by $6.3 million, primarily due to the income tax benefit recorded in the prior year as a result of a valuation allowance reversal related to deferred tax liabilities generated from the acquisition of IO Turbine. In addition, the prior year taxable income was substantially offset by net operating losses which are no longer available in the current year. The provision for income taxes for the three months ended September 30, 2012 was comprised of foreign income taxes as well as U.S. federal and state income taxes.

Financial Position, Liquidity, and Capital Resources

Primary Sources of Liquidity

As of September 30, 2012, our principal sources of liquidity consisted of cash and cash equivalents of $353.9 million, net accounts receivable of $65.7 million, and amounts available under our revolving line of credit of approximately $21.8 million. In June 2011, we completed an initial public offering of our common stock, or IPO, in which we issued and sold 12,600,607 shares and received net proceeds of approximately $218.9 million. In November 2011, we completed a follow-on public offering of our common stock in which we issued and sold 3,000,000 shares and received net proceeds of approximately $94.0 million. We had working capital of $414.5 million as of September 30, 2012.

In August 2011, we used approximately $17.6 million (net of cash acquired) of the net IPO proceeds as partial consideration to purchase IO Turbine. We anticipate using the remaining net proceeds from our public offerings for working capital and general corporate purposes, including expansion of our sales organization, further development and expansion of our product offerings and possible acquisitions of, or investments in, businesses, technologies, or other assets. We have no present material understandings, commitments, or agreements to enter into any acquisitions or investments. Our excess cash is primarily invested in money market funds.

Historically, our primary sources of liquidity have been from customer payments for our products and services, the issuance of common and convertible preferred stock and convertible notes, and proceeds from our revolving line of credit.

Investing activities		(21,799	)		(5,175	)
Financing activities		1,042			9,068

- 21 -

Operating Activities

Our operating cash flow primarily depends on the timing and amount of cash receipts from our customers, inventory purchases, and payments for operating expenses.

Our net cash provided by operating activities for the three months ended September 30, 2011 and 2012 was $3.1 million and $28.7 million, respectively. During these periods, cash collected from our customers exceeded our operating cash outflows, which consisted primarily of purchases of inventory and personnel-related costs.

Investing Activities

Cash flows from investing activities primarily relate to purchases of computer equipment, leasehold improvements, and property and equipment to support our growth. Investing activities also include cash used for business acquisitions.

During the three months ended September 30, 2011, our net cash used in investing activities was $21.8 million and was primarily due to cash paid for the acquisition of IO Turbine, net of cash acquired, of $17.6 million and purchases of property and equipment of $4.2 million.

During the three months ended September 30, 2012, our net cash used in investing activities was $5.2 million for purchases of property and equipment.

Financing Activities

Cash flows from financing activities primarily include net proceeds from issuances of common and convertible preferred stock, proceeds and payments related to issuances of convertible notes, and loans from a financial institution.

We generated $1.0 million of net cash from financing activities for the three months ended September 30, 2011, primarily due to $1.1 million in net proceeds from our employee stock purchase plan and exercise of stock options.

We generated $9.1 million of net cash from financing activities for the three months ended September 30, 2012, primarily due to $5.7 million in net proceeds from the exercise of stock options and our employee stock purchase plan, and $4.4 million from a tax benefit from the exercise of stock options, all offset by the issuance of restricted stock awards and restricted stock units, net of repurchases of $1.1 million.

Revolving Line of Credit

In September 2010, we amended and restated our loan and security agreement, or the revolving line of credit, with a financial institution. The revolving line of credit allows us to borrow up to a limit of $25.0 million. A sublimit of $6.0 million for letters of credit, certain cash management services, and foreign exchange forward contracts applied until May 2012. The total balance of letters of credit outstanding at September 30, 2012 was $3.2 million, which reduces the amount we have available to borrow under the revolving line of credit. Prior to May 2012, borrowings under the revolving line of credit would have accrued interest at a floating per annum rate equal to one-half of one percentage point (0.50%) above the prime rate as published in the Wall Street Journal. An unused commitment fee equal to 0.375% of the difference between the $25.0 million limit and the average daily balance of borrowings outstanding each quarter was due on the last day of such quarter. Prior to May 2012, the revolving line of credit was secured by substantially all of our assets. We can make advances against the revolving line of credit until its maturity date, at which time all unpaid principal and interest shall be due and payable.

In August 2011, we entered into an amendment to the revolving line of credit which provided for the consent of the financial institution with respect to the IO Turbine acquisition and certain amendments to provide us with further flexibility to consummate mergers and acquisitions permitted under the revolving line of credit.

In May 2012, we entered into a second amendment to the revolving line of credit. Pursuant to this amendment, the pricing on revolving line of credit was amended such that borrowings under the revolving line of credit accrue interest at a per annum rate equal to, at our option, a floating per annum rate equal to the prime rate as published in the Wall Street Journal, or the LIBOR rate (based on 1, 2, 3 or 6-month interest periods) plus a margin equal to two percent (2.00%) per annum. This amendment further provides for, among other things, (i) the reduction of the quarterly unused commitment fee to an amount equal to one-quarter of one percent (0.25%) per annum of the difference between the $25.0 million loan commitment and the average daily balance of borrowings outstanding on the last day of each quarter, (ii) the removal of the borrowing base formula and the sublimit restricting the issuance of letters of credit, cash management services and foreign exchange forward contracts, and (iii) the release of the financial institution’s security interest in all of our assets.

- 22 -

Under the terms of the revolving line of credit, we are required to maintain the following minimum financial covenants on a consolidated basis:

• A ratio of current assets to current liabilities plus, without duplication, any of our obligations to the financial institution, of at least 1.25 to 1.00.

• A tangible net worth of at least $25.0 million, plus 25% of the net proceeds we received from the sale or issuance of our equity or subordinated debt, such increase to be measured as of the last day of the quarter in which we received such proceeds.

In September 2012, we entered into a third amendment to the revolving line of credit. Pursuant to this amendment, the maturity date of the revolving line of credit was extended to December 2012.

As of September 30, 2012, no borrowings were outstanding under the revolving line of credit and we were in compliance with all covenants.

Future Capital Requirements

Our future capital requirements will depend on many factors, including our rate of revenue growth, possible acquisitions of, or investments in, businesses, technologies, or other assets, the expansion of our sales and marketing activities, the timing and extent of spending to support product development efforts, and the expansion into new territories, the timing of new product introductions, the building of infrastructure to support our growth, the continued market acceptance of our products, and strategic investments in businesses.

We believe that our cash and cash equivalents and available amounts under the revolving line of credit, will be sufficient to meet our working capital and capital expenditure requirements for at least the next 12 months. Although we are not currently a party to any material agreement or letter of intent regarding potential investments in, or acquisitions of, complementary businesses, applications, or technologies, we may enter into these types of arrangements, which could require us to seek additional equity or debt financing. If required, additional financing may not be available on terms that are favorable to us, if at all. If we raise additional funds through the issuance of equity or convertible debt securities, the percentage ownership of our stockholders will be reduced and these securities might have rights, preferences, and privileges senior to those of our current stockholders. We cannot assure you that additional financing will be available or that, if available, such financing can be obtained on terms favorable to our stockholders and us.

Off Balance Sheet Arrangements

During the periods presented, we did not have any relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purpose.

Contractual Obligations and Material Commitments

In May 2012, we entered into a minimum purchase commitment for raw materials inventory that ends in June 2013 and provides for a termination fee based on a percentage of the amount of raw materials inventory not taken under the commitment. As of September 30, 2012, approximately $21.5 million remained outstanding under this commitment.

Indemnification

We have agreed to indemnify our officers and directors for certain events or occurrences, while the officer or director is or was serving at our request in such capacity. The maximum amount of potential future indemnification is unlimited; however, we have a director and officer insurance policy that provides corporate reimbursement coverage that limits our exposure and enables us to recover a portion of any future amounts paid. We are unable to reasonably estimate the maximum amount that could be payable under these arrangements since these obligations are not capped but are conditional to the unique facts and circumstances involved. Accordingly, we had no liabilities recorded for these agreements as of June 30, 2012 and September 30, 2012.

Many of our agreements with customers and channel partners, including OEMs and resellers, generally include certain provisions for indemnifying the channel partners and customers against third-party claims of intellectual property infringement arising from the use of our products. To date, we have not incurred any material costs as a result of such indemnification provisions and have not accrued any liabilities related to such obligations in our condensed consolidated financial statements.

Critical Accounting Policies and Estimates

Our condensed consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles, or GAAP. The preparation of these condensed consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, expenses, and related disclosures. These estimates and assumptions are often based on judgments that we believe to be reasonable under the circumstances at the time made, but all such estimates and assumptions are inherently uncertain and unpredictable. Actual results may differ from those estimates and assumptions, and it is possible that

- 23 -

other professionals, applying their own judgment to the same facts and circumstances, could develop and support alternative estimates and assumptions that would result in material changes to our operating results and financial condition. We evaluate our estimates and assumptions on an ongoing basis. Our estimates are based on historical experience and various other assumptions that we believe to be reasonable under the circumstances. Our actual results could differ from these estimates.

Our critical accounting policies and estimates are detailed in Management’s Discussion and Analysis of Financial Condition and Results of Operations contained in Part II, Item 7 of our Annual Report on Form 10-K for the year ended June 30, 2012. None of our critical accounting policies and estimates have been significantly changed since the filing of our most recent Form 10-K except for those noted below.

Income Taxes

Significant judgment is required in determining our provision for income taxes and evaluating our uncertain tax positions. Historically, our effective tax rate has been volatile and difficult to forecast due to the valuation allowance against our deferred tax assets, stock based compensation, our ability to use tax credits and other adjustments. We expect this volatility to continue in our effective tax rate.

In evaluating our ability to recover our deferred tax assets, in full or in part, we consider all available positive and negative evidence, including reversal of taxable temporary differences, our past operating results, our forecast of future market growth, forecasted earnings, future taxable income, and prudent and feasible tax planning strategies. To the extent that we continue to generate positive income and expect, with reasonable certainty, to continue to generate positive income we may release all or a portion of our valuation allowance during fiscal year 2013. This release would result in the recognition of certain deferred tax assets and a decrease to income tax expense for the period such release is recorded.

Recently Issued and Adopted Accounting Pronouncements

For information with respect to recent accounting pronouncements and the impact of these pronouncements on our condensed consolidated financial statements, see Note 1 “Description of Business and Summary of Significant Accounting Policies – Recently Issued and Adopted Accounting Pronouncements” in the notes to condensed consolidated financial statements.

Segments

Operating segments are defined in accounting standards as components of an enterprise about which separate financial information is available and is regularly evaluated by management, namely the chief operating decision maker of an organization, in order to make operating and resource allocation decisions. We have concluded that we operate in one business segment, which is the development, marketing and sale of storage memory products. Substantially all of our revenue for all periods presented in the accompanying condensed consolidated statements of operations has been from sales of the ioDrive product lines and related customer support services.

Part I. Item 3. Quantitative and Qualitative Disclosures About Market Risk

Foreign Currency Risk

Our international sales and marketing operations incur expenses that are denominated in foreign currencies. Although our international operations are currently immaterial compared to our operations in the United States, we expect to continue to expand our international operations which will increase our potential exposure to fluctuations in foreign currencies. Our exposures are to fluctuations in exchange rates primarily for the U.S. dollar versus the euro and the British pound. Changes in currency exchange rates could adversely affect our consolidated results of operations or financial position. Additionally, our international sales and marketing operations maintain cash balances denominated in foreign currencies. In order to decrease the inherent risk associated with translation of foreign cash balances into our reporting currency, we have not maintained excess cash balances in foreign currencies. As of September 30, 2012, we had approximately $1.9 million of cash in foreign accounts. To date, we have not hedged our exposure to changes in foreign currency exchange rates and, as a result, could incur unanticipated translation gains and losses. Through September 30, 2012, all of our sales were billed in U.S. dollars and therefore not subject to direct foreign currency risk.

Part I. Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

As required by Rule 13a-15(b) under the Securities Exchange Act of 1934, as amended, or the Exchange Act, our management, including our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures, as defined in Rule 13a-15(e) under the Exchange Act. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of the end of the period covered by this report, our disclosure controls and procedures were effective.

- 24 -

Changes in Internal Control Over Financial Reporting

During the first quarter fiscal 2013, we implemented a stock-based compensation accounting system in our U.S. operations. During fiscal 2013 we plan to continue to enhance our enterprise resource planning system and continue to enhance our system of internal control over financial reporting. These items have not had an adverse impact on our business. There were no other changes in our internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15(d)-15(f) under the Securities Exchange Act of 1934) that occurred during our most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Part II. OTHER INFORMATION

Item 1. Legal Proceedings

On February 7, 2012, Entorian Technologies L.P., filed a lawsuit in the U.S. District Court for the District of Utah against our company. The complaint alleged that memory stacks included in some of our products infringe U.S. Patent No. 5,420,751, or the ‘751 patent, which expired in May 2012. Polystak, Inc. is our third-party supplier of the accused memory stack component. On March 1, 2012, Polystak filed a lawsuit against Entorian Technologies in the U.S. District Court for the Northern District of California. The complaint alleges that the ‘751 patent is invalid, and that Polystak’s memory stacks do not infringe the ‘751 patent. On March 8, 2012, Entorian Technologies dismissed the lawsuit against us in Utah. On March 9, 2012, Entorian Technologies filed a counterclaim against us and Polystak in the Northern District of California lawsuit. The counterclaim alleges that Fusion-io and Polystak infringe the ‘751 patent and seeks damages, but it does not seek an injunction. On September 4, 2012, the Court stayed this lawsuit pending reexamination of the ‘751 patent by the U.S. Patent Office. Polystak has agreed to indemnify and defend us with respect to these lawsuits.

On September 7, 2011, Solid State Storage Solutions, Inc., or S4, filed a lawsuit in U.S. District Court for the Eastern District of Texas against our company and eight other companies. The complaint alleges that our products infringe U.S. Patent Nos. 6,701,471; 7,234,087; 7,721,165; 6,370,059; 7,366,016; 7,746,697; 7,616,485; 6,341,085; 6,567,334; 6,347,051; 7,064,995; and 7,327,624. The complaint seeks both damages and a permanent injunction against us. We have limited information about the specific infringement allegations, but they appear to focus on storage controllers for flash memory and in particular to storage address mapping, I/O buffering, wear leveling, and reducing read latency in relation to interfacing with flash storage media. We use a custom programmed storage controller in our products. The Court has set a schedule calling for a patent claim construction hearing on January 9, 2013, and a trial commencing on July 1, 2013.

On May 18, 2011, Internet Machines LLC filed a lawsuit in U.S. District Court for the Eastern District of Texas against us and 20 other companies. The complaint alleges that our products infringe U.S. Patent Nos. 7,454,552; 7,421,532; 7,814,259; and 7,945,722. On August 26, 2011, Internet Machines MC LLC amended its prior complaint filed in U.S. District Court for the Eastern District of Texas against PLX Technology, Inc. to add our company and several other companies as defendants. This complaint alleges that our products infringe U.S. Patent No. 7,539,190. These complaints seek both damages and a permanent injunction against us. The specific infringement allegations appear to focus on a PCI switch component that, while used in some of our products, is manufactured by a third-party supplier. This third-party supplier was found to infringe the above identified U.S. Patent Nos. 7,454,552 and 7,421,532 by a jury in a prior case. The judge has stayed the lawsuits against us pending the entry of a final non-appealable judgment in the prior case between the third-party supplier and Internet Machines. The third-party supplier has agreed to indemnify and defend us with respect to these lawsuits.

Based on our preliminary investigations of the patents identified in the Entorian Technologies, Internet Machines and S4 complaints, we do not believe that our products infringe any valid or enforceable claim of the patents at issue in those complaints. Nevertheless, the costs associated with any actual, pending, or threatened litigation could negatively impact our operating results regardless of the actual outcome. In addition, we may, from time to time, be involved in various legal proceedings arising from the normal course of business activities, and an unfavorable resolution of any of these matters could materially affect our future results of operations, cash flows, or financial position.

Part II. Item 1A. Risk Factors

Our operations and financial results are subject to various risks and uncertainties, including those described below, which could adversely affect our business, financial condition, results of operations, cash flows, and the trading price of our common stock.

Risks Related to Our Business and Industry

Our limited operating history makes it difficult to evaluate our current business and future prospects, and may increase the risk of your investment.

We were founded in December 2005 and sold our first products in April 2007. The majority of our revenue growth has occurred since the three months ended December 31, 2009. We continue to innovate and develop enterprise data acceleration solutions. For example, we recently released our ION Data Accelerator software, our next generation ioDrive2 platforms, and our virtualization and automated data-tiering caching software. In addition, our current management team has only been working together for a relatively short period of time. Our limited operating history makes it difficult to evaluate our current business and our future prospects, including our ability to plan for and model future growth. We have encountered and will continue to encounter risks and difficulties frequently experienced by growing companies in rapidly changing industries, such as the risks described herein. If we do not address these risks successfully, our business and operating results would be adversely affected, and our stock price could decline.

- 26 -

Our revenue growth rate in recent periods is not expected to recur in the near term and may not be indicative of our future performance.

You should not consider our revenue growth in recent periods as indicative of our future performance. In fact, in future periods, our revenue could decline. We do not expect to achieve similar percentage revenue growth rates in future periods. We have experienced in the past, and continue to expect to experience, substantial concentrated purchases by customers to complete or upgrade large-scale datacenter deployments. Our revenue in any particular quarterly period could be disproportionately affected if this trend continues. You should not rely on our revenue for any prior quarterly or annual periods as an indication of our future revenue or revenue growth. If we are unable to maintain consistent revenue or revenue growth, our stock price could be volatile, and it may be difficult to achieve and maintain profitability.

We have experienced rapid growth in recent periods and we may not be able to sustain or manage any future growth effectively.

We have significantly expanded our overall business, customer base, headcount, and operations, and we anticipate that we will continue to grow our business. For example, from September 30, 2011 to September 30, 2012, our headcount increased from 499 to 733 employees, representing an increase of 234 employees. Our future operating results depend to a large extent on our ability to successfully manage our anticipated expansion and growth.

To manage our growth successfully, we believe we must effectively, among other things:

• maintain and extend our leadership in enterprise data acceleration;

• maintain and expand our existing original equipment manufacturer, or OEM, and channel partner relationships and develop new OEM and channel partner relationships;

• forecast and control expenses;

• recruit, hire, train, and manage additional research and development and sales personnel;

• expand our support capabilities;

• enhance and expand our distribution and supply chain infrastructure;

• manage inventory levels;

• enhance and expand our international operations; and

• implement, improve, and maintain our administrative, financial and operational systems, procedures, and controls.

We expect that our future growth will continue to place a significant strain on our managerial, administrative, operational, financial, and other resources. We will incur costs associated with this future growth prior to realizing the anticipated benefits, and the return on these investments may be lower, or may develop more slowly, than we expect or may be nonexistent. If we are unable to manage our growth effectively, we may not be able to take advantage of market opportunities or develop new products or enhancements to existing products and we may fail to satisfy end-users’ requirements, maintain product quality, execute on our business plan or respond to competitive pressures, each of which could adversely affect our business and operating results.

We expect large and concentrated purchases by a limited number of customers to continue to represent a substantial majority of our revenue, and any loss or delay of expected purchases could adversely affect our operating results.

Historically, large purchases by a relatively limited number of customers have accounted for a substantial majority of our revenue, and the composition of the group of our largest customers changes from period to period. Some of our customers make concentrated purchases to complete or upgrade specific large-scale data storage installations. These concentrated purchases are short-term in nature and are typically made on a purchase order basis rather than pursuant to long-term contracts. During the three months ended September 30, 2011 and 2012, sales to the 10 largest customers in each period, including the applicable OEMs, accounted for approximately 94% and 91% of revenue, respectively. Apple, through a reseller, our OEM customer HP, and our direct customer Facebook, each accounted for 46%, 22%, and less than 10% of our revenue, respectively, during the three months ended September 30, 2011, and 28%, 14%, and 28% of our revenue, respectively, during the three months ended September 30, 2012.

As a consequence of our limited number of customers and the concentrated nature of their purchases, our quarterly revenue and operating results may fluctuate from quarter to quarter and are difficult to estimate. For example, any acceleration or delay in anticipated product purchases or the acceptance of shipped products by our larger customers could materially impact our revenue and operating results in any quarterly period. Additionally, our revenue and operating results could be adversely affected if any of these larger customers purchase our competitors’ products instead of purchasing our products. We cannot provide any assurance that we will be able to sustain or increase our revenue from our larger customers or that we will be able to offset the discontinuation of concentrated purchases by our larger customers with purchases by new or existing customers. We expect that sales of our products to a limited number of customers will continue to contribute materially to our revenue for the foreseeable future, but that competition for these sales will increase. The loss of, or a significant delay or reduction in purchases by, a small number of customers could materially harm our business and operating results.

Our gross margins are impacted by a variety of factors, are subject to variation from period to period and are difficult to predict.

Our gross margins fluctuate from period to period due primarily to product costs, customer mix, and product mix. From the three months ended September 30, 2011 through the three months ended September 30, 2012, our quarterly gross margins ranged from 51.0% to 63.2%. Our gross margins are likely to continue to fluctuate and may be affected by a variety of factors, including:

• demand for our products;

• changes in customer, geographic, or product mix, including mix of configurations within products;

• significant new customer deployments;

• the cost of components and freight;

• changes in our manufacturing costs, including fluctuations in yields and production volumes;

• new product introductions and enhancements, potentially with initial sales at relatively small volumes and higher product costs;

• rebates, sales and marketing initiatives, discount levels, and competitive pricing;

• changes in the mix between direct versus indirect sales;

• the timing and amount of revenue recognized and deferred;

• excess inventory levels or purchase commitments as a result of changes in demand forecasts or last time buy purchases;

• write-downs due to excess and obsolete inventory;

• possible product and software defects and related increased warranty or repair costs;

• the timing of technical support service contracts and contract renewals;

• inventory stocking requirements to support new product introductions; and

• product quality and service ability issues.

Due to such factors, gross margins are subject to variation from period to period and are difficult to predict. If we are unable to manage these factors effectively, our gross margins may decline, and fluctuations in gross margin may make it difficult to manage our business and achieve or maintain profitability, which could materially harm our business and operating results.

Some of our larger customers require more favorable terms and conditions from their vendors and may request pricing concessions. As we seek to sell more products to these customers, we may be required to agree to terms and conditions that may have an adverse effect on our business or ability to recognize revenue.

Some of our larger customers have significant purchasing power and, accordingly, have requested and received more favorable terms and conditions, including lower prices, than we typically provide. As we seek to sell more products to this class of customer, we may be required to agree to these terms and conditions, which may include terms that affect the timing of our revenue recognition or may reduce our gross margins and have an adverse effect on our business and operating results.

The future growth of our sales to OEMs is dependent on OEM customers incorporating our products into their server and data storage systems and the OEM’s sales efforts. Any failure to grow our OEM sales and maintain relationships with OEMs could adversely affect our business, operating results and financial condition.

Sales of our products to OEMs represent a significant portion of our revenue and we anticipate that our OEM sales will constitute a substantial portion of our future sales. In some cases, our products must be designed into the OEM’s products. If that fails to occur for a given product line of an OEM, we would likely be unable to sell our products to that OEM for such product line during the life cycle of that product. Even if an OEM integrates one or more of our products into its server, data storage systems or appliance solutions, we cannot be assured that its product will be commercially successful, and as a result, our sales volumes may be less than anticipated. Our OEM customers are typically not obligated to purchase our products and can choose at any time to stop using our products, if their own systems are not commercially successful or if they decide to pursue other strategies or for any other reason, including the incorporation or development of competing products by these OEMs. Moreover, our OEM customers may not devote sufficient attention and resources to selling our products. We may not be able to develop or maintain relationships with OEMs for a number of reasons, including because of the OEM’s relationships with our competitors or prospective competitors or other incentives that may not motivate their internal sales forces to promote our products. In addition, direct sales of our ioDrive and ioDrive2 product lines may compete with products sold by our OEM partners, and our OEM partners may compete directly with our other OEM partners, which may affect the commitment of our OEM partners to sell our products. Even if we are successful in selling through OEMs, we expect that sales through OEMs will be a lower gross margin business than our direct sales business. If we are unable to grow our OEM sales, if our OEM customers’ systems incorporating our products are not commercially successful, if our products,

- 28 -

including new and next generation products, are not designed into a given OEM product cycle, if we fail to minimize conflicts between our channel partners, in particular OEMs, if our OEM customers do not timely qualify our products for promotion or sale by them, or if our OEM customers significantly reduce, cancel, or delay their orders with us, our revenue would suffer and our business, operating results, and financial condition could be materially adversely affected.

Ineffective management of our inventory levels could adversely affect our operating results.

If we are unable to properly forecast, monitor, control, and manage our inventory and maintain appropriate inventory levels and mix of products to support our customers’ needs, we may incur increased and unexpected costs associated with our inventory. Sales of our products are generally made through individual purchase orders and some of our customers place large orders with short lead times, which make it difficult to predict demand for our products and the level of inventory that we need to maintain to satisfy customer demand. If we build our inventory in anticipation of future demand that does not materialize, or if a customer cancels or postpones outstanding orders, we could experience an unanticipated increase in levels of our finished products. For some customers, even if we are not contractually obligated to accept returned products, we may determine that it is in our best interest to accept returns in order to maintain good relationships with those customers. Product returns would increase our inventory and reduce our revenue. If we are unable to sell our inventory in a timely manner, we could incur additional carrying costs, reduced inventory turns, and potential write-downs due to obsolescence.

Alternatively, we could carry insufficient inventory, and we may not be able to satisfy demand, which could have a material adverse effect on our customer relationships or cause us to lose potential sales.

We have often experienced order changes including delivery delays and fluctuations in order levels from period-to-period, and we expect to continue to experience similar delays and fluctuations in the future, which could result in fluctuations in inventory levels, cash balances, and revenue.

The occurrence of any of these risks could adversely affect our business, operating results, and financial condition.

Our operating results may fluctuate significantly, which could make our future results difficult to predict and could cause our operating results to fall below expectations.

Our operating results may fluctuate due to a variety of factors, many of which are outside of our control. As a result, comparing our operating results on a period-to-period basis may not be meaningful. You should not rely on our past results as an indication of our future performance. If our revenue or operating results fall below the expectations of investors or any securities analysts that follow our company, the price of our common stock would likely decline.

Factors that are difficult to predict and that could cause our operating results to fluctuate include:

• the timing and magnitude of orders, shipments, and acceptance of our products in any quarter;

• our ability to control the costs of the components we use in our hardware products;

• disruption in our supply chains, component availability, and related procurement costs;

• reductions in customers’ budgets for information technology purchases;

• delays in customers’ purchasing cycles or deferments of customers’ product purchases in anticipation of new products or updates from us or our competitors;

• fluctuations in demand and prices for our products;

• changes in industry standards in the data storage industry;

• our ability to develop, introduce, and ship in a timely manner new products and product enhancements that meet customer requirements;

• the timing of product releases or upgrades or announcements by us or our competitors;

• any change in the competitive dynamics of our markets, including new entrants or discounting of product prices;

• our ability to control costs, including our operating expenses; and

• future accounting pronouncements and changes in accounting policies.

The occurrence of any one of these risks could negatively affect our operating results in any particular quarter, which could cause the price of our common stock to decline.

- 29 -

We have incurred significant net losses during our limited operating history and may not consistently achieve or maintain profitability.

Prior to the three months ended March 31, 2011, we had incurred net losses in each quarter since our inception and again incurred net losses in the three months ended December 31, 2011, March 31, 2012, and June 30, 2012. We may incur losses in future periods as we continue to increase our expenses in all areas of our operations to support our growth. If our revenue does not increase to offset these expected increases in operating expenses, we will not be profitable. As of September 30, 2012, we had an accumulated deficit of approximately $67 million.

Changes in our provision for income taxes or adverse outcomes resulting from examination of our income tax returns could adversely affect our results.

Our provision for income taxes is subject to volatility and could be adversely affected by several factors, many of which are outside of our control, including:

• changes in the valuation of our deferred tax assets and liabilities;

• changes in the research and development tax credit laws;

• an increase in non-deductible expenses for tax purposes, including certain stock-based compensation expense and impairment of goodwill;

• transfer pricing adjustments;

• earnings being lower than anticipated in countries that have lower tax rates and higher than anticipated in countries that have higher tax rates;

• changes in the income allocation methods for state taxes;

• a change in the pattern of stock option exercises by our employees;

• tax assessments resulting from income tax audits or any related tax interest or penalties that could significantly affect our income tax provision for the period in which the settlement takes place;

• a change in our decision to indefinitely reinvest foreign earnings;

• changes in accounting principles;

• the tax effects of purchase accounting for acquisitions and restructuring charges that may cause fluctuations between reporting periods;

• imposition of withholding or other taxes on payments by subsidiaries or customers; or

• changes in tax laws or related interpretations, accounting standards, regulations, and interpretations in multiple tax jurisdictions in which we operate.

Significant judgment is required to determine the recognition and measurement attribute prescribed in Accounting Standards Codification 740. In addition, the standard applies to all income tax positions, including the potential recovery of previously paid taxes, which if settled unfavorably could adversely impact our provision for income taxes or additional paid-in capital.

In evaluating our ability to recover our deferred tax assets, in full or in part, we consider all available positive and negative evidence, including reversal of taxable temporary differences, our past operating results, our forecast of future market growth, forecasted earnings, and future taxable income, and prudent and feasible tax planning strategies. The assumptions utilized in determining future taxable income require significant judgment and are consistent with the plans and estimates we are using to manage the underlying businesses. Due to historical net losses incurred and the uncertainty of realizing the deferred tax assets, for all the periods presented, we have a full valuation allowance against our deferred tax assets. We will continue to assess the need for a valuation allowance on the deferred tax assets by evaluating both positive and negative evidence that may exist. To the extent that we continue to generate positive income and expect, with reasonable certainty, to continue to generate positive income we may release all or a portion of our valuation allowance during fiscal 2013. This release would result in the recognition of certain deferred tax assets and a decrease to income tax expense for the period such release is recorded. The release of all or a portion of the valuation allowance will have a significant effect on our tax expense in the period it is released.

As a multinational corporation, we conduct our business in many countries and are subject to taxation in many jurisdictions. The taxation of our business is subject to the application of multiple and sometimes conflicting tax laws and regulations as well as multinational tax conventions. Our effective tax rate is dependent upon the availability of tax credits and carryforwards. The application of tax laws and regulations is subject to legal and factual interpretation, judgment and uncertainty. Tax laws themselves are subject to change as a result of changes in fiscal policy, changes in legislation, and the evolution of regulations and court rulings. Consequently, taxing authorities may impose tax assessments or judgments against us that could materially impact our tax liability and/or our effective income tax rate.

- 30 -

In addition, we may be subject to examination of our income tax returns by the Internal Revenue Service and other tax authorities. If tax authorities challenge the relative mix of our U.S. and international income, our future effective income tax rates could be adversely affected. While we regularly assess the likelihood of adverse outcomes from such examinations and the adequacy of our provision for income taxes, there can be no assurance that such provision is sufficient and that a determination by a tax authority will not have an adverse effect on our business, financial condition and results of operations.

Our sales cycles can be long and unpredictable, particularly with respect to large orders and OEM relationships, and our sales efforts require considerable time and expense. As a result, it can be difficult for us to predict when, if ever, a particular customer will choose to purchase our products, which may cause our operating results to fluctuate significantly.

Our sales efforts involve educating our customers about the use and benefits of our products, including their technical capabilities and cost saving potential. Customers often undertake an evaluation and testing process that can result in a lengthy sales cycle. We spend substantial time and resources on our sales efforts without any assurance that our efforts will produce any sales. In addition, product purchases are frequently subject to budget constraints, multiple approvals, and unplanned administrative, processing, and other delays. Additionally, a significant portion of our sales personnel have been with us for less than a year, and we continue to increase our number of sales personnel, which could further extend the sales cycle as these new personnel are typically not immediately productive. These factors, among others, could result in long and unpredictable sales cycles, particularly with respect to large orders.

We also sell to OEMs that incorporate our solutions into their products, which can require an extended evaluation, testing, and qualification process before our product is approved for inclusion in one of their product lines. We also may be required to customize our product to interoperate with an OEM’s product, which could further lengthen the sales cycle for OEM customers. The length of our sales cycle for an OEM makes us susceptible to the risk of delays or termination of orders if end-users decide to delay or withdraw funding for datacenter projects, which could occur for various reasons, including global economic cycles and capital market fluctuations.

As a result of these lengthy and uncertain sales cycles of our products, it is difficult for us to predict when customers may purchase and accept products from us and as a result, our operating results may vary significantly and may be adversely affected.

We compete with large storage and software providers and expect competition to intensify in the future from established competitors and new market entrants.

The market for data storage products is highly competitive, and we expect competition to intensify in the future. Our products compete with various traditional datacenter architectures, including high performance server and storage approaches. These may include the traditional data storage providers, including storage array vendors such as EMC Corporation and Hitachi Data Systems, who typically sell centralized storage products as well as high-performance storage approaches utilizing solid state disks, as well as vertically integrated appliance vendors such as Oracle. In this regard, EMC recently introduced a product designed to compete with our caching solutions. In addition, we may also compete with enterprise solid state disk vendors such as Huawei Technologies, Co., Intel Corp., LSI Corporation, Marvell Semiconductor, Inc., Micron Technology, Inc., OCZ Technology Group, Inc., Samsung Electronics, Inc., SanDisk, Corp., Seagate Technology, STEC, Inc., Toshiba Corp., and Western Digital Corp. Our ION Data Accelerator software competes with proprietary integrated flash appliances from EMC Corporation, HP 3PAR by Hewlett-Packard Development Company, Texas Memory Systems, an IBM company, and a number of privately held companies. Our ioTurbine intelligent caching software, competes with solutions from EMC, Oracle, STEC’s open-source based product, and a privately held company. A number of new, privately held companies are currently attempting to enter our market, one or more of which may become significant competitors in the future.

Many of our current competitors have, and some of our potential competitors could have, longer operating histories, greater name recognition, larger customer bases, and significantly greater financial, technical, sales, marketing, and other resources than we have. Potential customers may prefer to purchase from their existing suppliers rather than a new supplier regardless of product performance or features. New start-up companies continue to innovate and may invent similar or superior products and technologies that may compete with our products and technology. Some of our competitors have made acquisitions of businesses that may allow them to offer more directly competitive and comprehensive solutions than they had previously offered. In addition, some of our competitors, including our OEM customers, may develop competing technologies and sell at zero or negative margins, through product bundling, closed technology platforms, or otherwise, to gain business. Our current and potential competitors may also establish cooperative relationships among themselves or with third parties. As a result, we cannot assure you that our products will continue to compete favorably, and any failure to do so could seriously harm our business, operating results, and financial condition.

- 31 -

Competitive factors could make it more difficult for us to sell our products, resulting in increased pricing pressure, reduced gross margins, increased sales and marketing expenses, longer customer sales cycles, and failure to increase, or the loss of, market share, any of which could seriously harm our business, operating results, and financial condition. Any failure to meet and address these competitive challenges could seriously harm our business and operating results.

The market for non-volatile storage memory products is developing and rapidly evolving, which makes it difficult to forecast end-user adoption rates and demand for our products.

The market for non-volatile storage memory products is developing and rapidly evolving. Accordingly, our future financial performance will depend in large part on growth in this market and on our ability to adapt to emerging demands in this market. Sales of our products currently are dependent in large part upon demand in markets that require high performance data storage solutions such as computing, Internet, and financial services. It is difficult to predict with any precision end-user adoption rates, end-user demand for our products or the future growth rate and size of our market. The rapidly evolving nature of the technology in the data storage products market, as well as other factors that are beyond our control, reduce our ability to accurately evaluate our future outlook and forecast quarterly or annual performance. Our products may never reach mass adoption, and changes or advances in technologies could adversely affect the demand for our products. Further, although Flash-based data storage products have a number of advantages compared to other data storage alternatives, Flash-based storage devices have certain disadvantages as well, including a higher price per gigabyte of storage, potentially shortened product lifespan, more limited methods for data recovery and lower performance for certain uses, including sequential input / output transactions and increased utilization of host system resources than traditional storage, and may require end-users to modify or replace network systems originally made for traditional storage media. A reduction in demand for Flash-based data storage caused by lack of end-user acceptance, technological challenges, competing technologies, and products or otherwise would result in a lower revenue growth rate or decreased revenue, either of which could negatively impact our business and operating results.

If our industry experiences declines in average sales prices, it may result in declines in our revenue and gross profit.

The industry for data storage products is highly competitive and has historically been characterized by declines in average sales prices. It is possible that the market for decentralized storage solutions could experience similar trends. Our average sales prices could decline due to pricing pressure caused by several factors, including competition, the introduction of competing technologies, overcapacity in the worldwide supply of Flash-based or similar memory components, increased manufacturing efficiencies, implementation of new manufacturing processes, and expansion of manufacturing capacity by component suppliers. If we are required to decrease our prices to be competitive and are not able to offset this decrease by increases in volume of sales or the sales of new products with higher margins, our gross margins and operating results would likely be adversely affected.

Developments or improvements in storage system technologies may materially adversely affect the demand for our products.

Significant developments in data storage systems, such as advances in solid state storage drives or improvements in non-volatile memory, may materially and adversely affect our business and prospects in ways we do not currently anticipate. For example, improvements in existing data storage technologies, such as a significant increase in the speed of traditional interfaces for transferring data between storage and a server or the speed of traditional embedded controllers, could emerge as preferred alternative to our products especially if they are sold at lower prices. This could be the case even if such advances do not deliver all of the benefits of our products. Any failure by us to develop new or enhanced technologies or processes, or to react to changes or advances in existing technologies, could materially delay our development and introduction of new products, which could result in the loss of competitiveness of our products, decreased revenue, and a loss of market share to competitors.

We derive substantially all of our revenue from our storage memory products, and a decline in demand for these products would cause our revenue to grow more slowly or to decline.

Our storage memory products account for substantially all of our revenue and will continue to comprise a significant portion of our revenue for the foreseeable future. As a result, our revenue could be reduced by:

• the failure of our storage memory products to achieve broad market acceptance;

• any decline or fluctuation in demand for our storage memory products, whether as a result of product obsolescence, technological change, customer budgetary constraints or other factors;

• the introduction of products and technologies that serve as a replacement or substitute for, or represent an improvement over, these products; and

• our inability to release enhanced versions of our products, including any related software, on a timely basis.

If the storage markets grow more slowly than anticipated or if demand for our products declines, we may not be able to increase our revenue sufficiently to achieve and maintain profitability and our stock price would decline.

- 32 -

If we fail to develop and introduce new or enhanced products on a timely basis, including innovations in our software offerings, our ability to attract and retain customers could be impaired and our competitive position could be harmed.

We operate in a dynamic environment characterized by rapidly changing technologies and industry standards and technological obsolescence. To compete successfully, we must design, develop, market, and sell new or enhanced products that provide increasingly higher levels of performance, capacity, and reliability and meet the cost expectations of our customers. The introduction of new products by our competitors, the market acceptance of products based on new or alternative technologies, or the emergence of new industry standards could render our existing or future products obsolete. Our failure to anticipate or timely develop new or enhanced products or technologies in response to technological shifts could result in decreased revenue and harm our business. If we fail to introduce new or enhanced products that meet the needs of our customers or penetrate new markets in a timely fashion, we will lose market share and our operating results will be adversely affected.

In order to maintain or increase our gross margins, we will need to continue to create valuable software solutions to be integrated with our storage memory products. Any new feature or application that we develop or acquire may not be introduced in a timely or cost-effective manner and may not achieve the broad market acceptance necessary to help increase our overall gross margins. If we are unable to successfully develop or acquire, and then market and sell our next generation products, our ability to increase our revenue and gross margin will be adversely affected.

Our products are highly technical and may contain undetected defects, which could cause data unavailability, loss or corruption that might, in turn, result in liability to our customers and harm to our reputation and business.

Our products are highly technical and complex and are often used to store information critical to our customers’ business operations. Our products may contain undetected errors, defects, or security vulnerabilities that could result in data unavailability, loss, or corruption or other harm to our customers. Some errors in our products may only be discovered after they have been installed and used by customers. Any errors, defects, or security vulnerabilities discovered in our products after commercial release could result in a loss of revenue or delay in revenue recognition, injury to our reputation, a loss of customers or increased service and warranty costs, any of which could adversely affect our business. In addition, we could face claims for product liability, tort, or breach of warranty. Many of our contracts with customers contain provisions relating to warranty disclaimers and liability limitations, which may be difficult to enforce. Defending a lawsuit, regardless of its merit, would be costly and might divert management’s attention and adversely affect the market’s perception of us and our products. In addition, our business liability insurance coverage could prove inadequate with respect to a claim and future coverage may be unavailable on acceptable terms or at all. These product-related issues could result in claims against us and our business could be adversely impacted.

Our products must interoperate with operating systems, software applications and hardware that is developed by others and if we are unable to devote the necessary resources to ensure that our products interoperate with such software and hardware, we may fail to increase, or we may lose, market share and we may experience a weakening demand for our products.

Our products must interoperate with our customers’ existing infrastructure, specifically their networks, servers, software, and operating systems, which may be manufactured by a wide variety of vendors and OEMs. When new or updated versions of these software operating systems or applications are introduced, we must sometimes develop updated versions of our software so that our products will interoperate properly. We may not accomplish these development efforts quickly, cost-effectively, or at all. These development efforts require capital investment and the devotion of engineering resources. If we fail to maintain compatibility with these applications, our customers may not be able to adequately utilize the data stored on our products, and we may, among other consequences, fail to increase, or we may lose, market share and experience a weakening in demand for our products, which would adversely affect our business, operating results, and financial condition.

Our products must conform to industry standards in order to be accepted by customers in our markets.

Generally, our products comprise only a part of a datacenter. The servers, network, software, and other components and systems of a datacenter must comply with established industry standards in order to interoperate and function efficiently together. We depend on companies that provide other components of the servers and systems in a datacenter to support prevailing industry standards. Often, these companies are significantly larger and more influential in driving industry standards than we are. Some industry standards may not be widely adopted or implemented uniformly, and competing standards may emerge that may be preferred by our customers. If larger companies do not support the same industry standards that we do, or if competing standards emerge, market acceptance of our products could be adversely affected, which would harm our business, operating results, and financial condition.

We rely on our key technical, sales and management personnel to grow our business, and the loss of one or more key employees or the inability to attract and retain qualified personnel could harm our business.

Our success and future growth depends to a significant degree on the skills and continued services of our key technical, sales and management personnel. In particular, we are highly dependent on the services of our Chief Executive Officer, David Flynn. All of our employees work for us on an at-will basis, and we could experience difficulty in retaining members of our senior management

- 33 -

team. We do not have “key person” life insurance policies that cover any of our officers or other key employees, other than our Chief Executive Officer. The loss of the services of any of our key employees could disrupt our operations, delay the development and introduction of our products, and negatively impact our business, prospects, and operating results.

We plan to hire additional personnel in all areas of our business, particularly for sales and research and development. Competition for these types of personnel is intense. We cannot assure you that we will be able to successfully attract or retain qualified personnel. Our inability to retain and attract the necessary personnel could adversely affect our business, operating results, and financial condition.

Our current research and development efforts may not produce successful products that result in significant revenue in the near future, if at all.

Developing our products and related enhancements is expensive. Our investments in research and development may not result in marketable products or may result in products that are more expensive than anticipated, take longer to generate revenue or generate less revenue, than we anticipate. Our future plans include significant investments in research and development and related product opportunities. We believe that we must continue to dedicate a significant amount of resources to our research and development efforts to maintain our competitive position. However, we may not receive significant revenue from these investments in the near future, if at all, which could adversely affect our business and operating results.

Our ability to sell our products is dependent in part on ease of use and the quality of our support offerings, and any failure to offer high-quality technical support would harm our business, operating results, and financial condition.

Although our products are designed to be interoperable with existing servers and systems, we may need to provide customized installation and configuration support to our customers before our products become fully operational in their environments. Once our products are deployed within our customers’ datacenters, they depend on our support organization to resolve any technical issues relating to our products. Our ability to provide effective support is largely dependent on our ability to attract, train, and retains qualified personnel. In addition, our sales process is highly dependent on our product and business reputation and on strong recommendations from our existing customers. Any failure to maintain high-quality installation and technical support, or a market perception that we do not maintain high-quality support, could harm our reputation, adversely affect our ability to sell our products to existing and prospective customers, and could harm our business, operating results, and financial condition.

If we fail to successfully maintain or grow our reseller and other channel partner relationships, our business and operating results could be adversely affected.

Our ability to maintain or grow our revenue will depend, in part, on our ability to maintain our arrangements with our existing channel partners and to establish and expand arrangements with new channel partners. Our channel partners may choose to discontinue offering our products or may not devote sufficient attention and resources toward selling our products. For example, our competitors may provide incentives to our existing and potential channel partners to use or purchase their products and services or to prevent or reduce sales of our products. The occurrence of any of these events could adversely affect our business and operating results.

We are exposed to the credit risk of some of our customers and to credit exposure in weakened markets, which could result in material losses.

Most of our sales are on an open credit basis. As a general matter, we monitor individual customer payment capability in granting open credit arrangements and may limit these open credit arrangements based on creditworthiness. We also maintain reserves we believe are adequate to cover exposure for doubtful accounts. Although we have programs in place that are designed to monitor and mitigate these risks, we cannot assure you these programs will be effective in reducing our credit risks, especially as we expand our business internationally. If we are unable to adequately control these risks, our business, operating results, and financial condition could be harmed.

We currently rely on contract manufacturers to manufacture our products, and our failure to manage our relationship with our contract manufacturers successfully could negatively impact our business.

We rely on several contract manufacturers to manufacture our products. We continue to evaluate other contract manufacturers. We currently do not have any long-term manufacturing contracts with these contract manufacturers. Our reliance on these contract manufacturers reduces our control over the assembly process, exposing us to risks, including reduced control over quality assurance, production costs, and product supply. If we fail to manage our relationship with these contract manufacturers effectively, or if these contract manufacturers experience delays, disruptions, capacity constraints, or quality control problems in their operations, our ability to ship products to our customers could be impaired and our competitive position and reputation could be harmed. If we are required to change contract manufacturers or assume internal manufacturing operations, we may lose revenue, incur increased costs, and damage our customer relationships. Qualifying a new contract manufacturer and commencing production is expensive and time-

- 34 -

consuming. We may need to increase our component purchases, contract manufacturing capacity, and internal test and quality functions if we experience increased demand. The inability of these contract manufacturers to provide us with adequate supplies of high-quality products, could cause a delay in our order fulfillment, and our business, operating results, and financial condition would be adversely affected.

We rely on a limited number of suppliers, and in some cases single-source suppliers, and any disruption or termination of these supply arrangements could delay shipments of our products and could materially and adversely affect our relationships with current and prospective customers.

We rely on a limited number of suppliers, and in some cases single-source suppliers, for several key components of our products, and we have not generally entered into agreements for the long-term purchase of these components. This reliance on a limited number of suppliers and the lack of any guaranteed sources of supply exposes us to several risks, including:

• the inability to obtain an adequate supply of key components, including non-volatile memory and reprogrammable controllers;

• price volatility for the components of our products;

• failure of a supplier to meet our quality, yield, or production requirements;

• failure of a key supplier to remain in business or adjust to market conditions; and

• consolidation among suppliers, resulting in some suppliers exiting the industry or discontinuing the manufacture of components.

As a result of these risks, we cannot assure you that we will be able to obtain enough of these key components in the future or that the cost of these components will not increase. If our supply of certain components is disrupted or delayed, or if we need to replace our existing suppliers, there can be no assurance that additional supplies or components will be available when required or that supplies will be available on terms that are favorable to us, which could extend our lead times, increase the costs of our components and materially adversely affect our business, operating results, and financial condition. If we are successful in growing our business, we may not be able to continue to procure components at current prices, which would require us to enter into longer term contracts with component suppliers to obtain these components at competitive prices. This could increase our costs and decrease our gross margins, harming our operating results.

Our results of operations could be affected by natural events in locations in which our customers or suppliers operate.

Several of our customers and suppliers have operations in locations that are subject to natural disasters, such as severe weather and geological events, which could disrupt the operations of those customers and suppliers. For example, in March 2011, the northern region of Japan experienced a severe earthquake followed by a tsunami. These geological events caused significant damage in that region and have adversely affected Japan’s infrastructure and economy. Some of our customers and suppliers are located in Japan and they have experienced, and may experience in the future, shutdowns as a result of these events, and their operations may be negatively impacted by these events. Our customers affected by this or a future natural disaster could postpone or cancel orders of our products, which could negatively impact our business. Moreover, should any of our key suppliers fail to deliver components to us as a result of this or a future natural disaster, we may be unable to purchase these components in necessary quantities or may be forced to purchase components in the open market at significantly higher costs. We may also be forced to purchase components in advance of our normal supply chain demand to avoid potential market shortages. In addition, if we are required to obtain one or more new suppliers for components or use alternative components in our solutions, we may need to conduct additional testing of our solutions to ensure those components meet our quality and performance standards, all of which could delay shipments to our customers and adversely affect our financial condition and results of operations.

To the extent we purchase excess or insufficient component inventory in connection with discontinuations by our vendors of components used in our products, our business or operating results may be adversely affected.

It is common in the storage and networking industries for component vendors to discontinue the manufacture of certain types of components from time to time due to evolving technologies and changes in the market. A supplier’s discontinuation of a particular type of component, such as a specific size of NAND Flash memory, may require us to make significant “last time” purchases of component inventory that is being discontinued by the vendor to ensure supply continuity until the transition to products based on next generation components or until we are able to secure an alternative supply. To the extent we purchase insufficient component inventory in connection with these discontinuations, we may experience delayed shipments, order cancellations or otherwise purchase more expensive components to meet customer demand, which could result in reduced gross margins. Alternatively, to the extent we purchase excess component inventory that we cannot use in our products due to obsolescence, we could be required to reduce the carrying value of inventory or be required to sell the components at or below our carrying value, which could reduce our gross margins.

Our business may be adversely affected if we encounter difficulties as we upgrade our enterprise resource planning system, or ERP, and other information technology systems.

We have substantially completed the upgrade of our ERP system and other information technology systems. Because we are in the process of upgrading and implementing these systems, this upgrading and implementation poses a risk to our internal controls over financial reporting and to our business operations. Disruptions or difficulties in upgrading and implementing these systems or the related procedures or controls could adversely affect both our internal and disclosure controls and harm our business, including our ability to forecast or make sales, manage our supply chain, and collect our receivables. Moreover, such a disruption could result in unanticipated costs or expenditures and a diversion of management’s attention and resources.

We will need to achieve and maintain effective internal control over financial reporting in accordance with Section 404 of the Sarbanes-Oxley Act and the failure to do so could have a material adverse effect on our business and stock price.

The Sarbanes-Oxley Act requires, among other things, that we maintain effective internal control over financial reporting and disclosure controls and procedures. We are required to perform system and process evaluation and testing of our internal control over financial reporting to allow management and our independent registered public accounting firm to report on the effectiveness of our internal control over financial reporting, as required by Section 404 of the Sarbanes-Oxley Act, or Section 404. Our compliance with Section 404 will require that we continue to incur substantial expense and expend significant management efforts. If we are unable to comply with the requirements of Section 404 in a timely manner, or if we or our independent registered public accounting firm notes or identifies deficiencies in our internal control over financial reporting that are deemed to be material weaknesses, the market price of our stock could decline and we could be subject to sanctions or investigations by the New York Stock Exchange, the SEC, or other regulatory authorities, which would require additional financial and management resources.

Third-party claims that we are infringing intellectual property, whether successful or not, could subject us to costly and time-consuming litigation or expensive licenses, and our business could be harmed.

The storage and networking industries are characterized by the existence of a large number of patents, copyrights, trademarks and trade secrets and by frequent litigation based on allegations of infringement or other violations of intellectual property rights. We have in the past received and may in the future receive inquiries from other intellectual property holders and may become subject to claims that we infringe their intellectual property rights, particularly as we expand our presence in the market and face increasing competition. For example, in 2011, we received two letters from Entorian Technologies, Inc. alleging that memory stacks included in our products infringe its U.S. Patent No. 5,420,751, or the ‘751 patent. Polystak, Inc. is our supplier of the accused memory stack component. On February 7, 2012, Entorian Technologies filed a lawsuit in the U.S. District Court for the District of Utah against our company. The complaint alleged that our products infringe the ‘751 patent, which expired in May 2012. On March 1, 2012, Polystak filed a lawsuit against Entorian Technologies in the U.S. District Court for the Northern District of California. The complaint alleges that the ‘751 patent is invalid, and that Polystak’s memory stacks do not infringe the ‘751 patent. On March 8, 2012, Entorian Technologies dismissed the lawsuit against us in Utah. On March 9, 2012, Entorian Technologies filed a counterclaim against Polystak and us in the Northern District of California lawsuit. The counterclaim alleges infringement of the ‘751 patent by Polystak and us and seeks damages, but it does not seek an injunction. On September 4, 2012, the Court stayed this lawsuit pending reexamination of the ‘751 patent by the U.S. Patent Office. Based on our preliminary investigation, we do not believe that our products infringe any valid or enforceable claim of the ‘751 patent. Polystak has agreed to indemnify and defend us with respect to these lawsuits. Nevertheless, the costs associated with any actual, pending, or threatened litigation could negatively impact our operating results regardless of the actual outcome.

In addition, on May 18, 2011, Internet Machines LLC filed a lawsuit in U.S. District Court for the Eastern District of Texas against our company and 20 other companies. The complaint alleges that our products infringe U.S. Patent Nos. 7,454,552; 7,421,532; 7,814,259; and 7,945,722. On August 26, 2011, Internet Machines MC LLC amended its prior complaint filed in U.S. District Court for the Eastern District of Texas against PLX Technology, Inc. to add our company and several other companies as defendants. This complaint alleges that our products infringe U.S. Patent No. 7,539,190. These complaints seek both damages and a permanent injunction against us. The specific infringement allegations appear to focus on a PCI switch component that, while used in some of our products, is manufactured by a third-party supplier. This third-party supplier was found to infringe U.S. Patent Nos. 7,454,552 and 7,421,532 by a jury in a prior case. The judge has stayed the lawsuits against us pending the entry of a final non-appealable judgment in the prior case between the third-party supplier and Internet Machines. The third-party supplier has agreed to indemnify and defend us with respect to these lawsuits. Based upon our preliminary investigation of the patents identified in the complaints, we do not believe that our products infringe any valid or enforceable claim of these patents. Nevertheless, the costs associated with any actual, pending, or threatened litigation could negatively impact our operating results regardless of the actual outcome.

Moreover, on September 7, 2011, Solid State Storage Solutions, Inc., or S4, filed a lawsuit in U.S. District Court for the Eastern District of Texas against our company and eight other companies. The complaint alleges that our products infringe U.S. Patent Nos. 6,701,471; 7,234,087; 7,721,165; 6,370,059; 7,366,016; 7,746,697; 7,616,485; 6,341,085; 6,567,334; 6,347,051; 7,064,995; and 7,327,624. The complaint seeks both damages and a permanent injunction against us. We have limited information about the specific infringement allegations, but they appear to focus on storage controllers for flash memory and in particular to storage address

- 36 -

mapping, I/O buffering, wear leveling, and reducing read latency in relation to interfacing with flash storage media. We use a custom programmed storage controller in our products. The Court has set a schedule calling for a patent claim construction hearing on January 9, 2013, and a trial commencing on July 1, 2013. Based on our preliminary investigation of the patents identified in the complaint, we do not believe that our products infringe any valid or enforceable claim of these patents. Nevertheless, the costs associated with any actual, pending, or threatened litigation could negatively impact our operating results regardless of the actual outcome.

We currently have a number of agreements in effect pursuant to which we have agreed to defend, indemnify, and hold harmless our customers, suppliers, and channel partners from damages and costs which may arise from the infringement by our products of third-party patents, trademarks, or other proprietary rights. The scope of these indemnity obligations varies, but may, in some instances, include indemnification for damages and expenses, including attorneys’ fees. Our insurance may not cover intellectual property infringement claims. A claim that our products infringe a third party’s intellectual property rights, if any, could harm our relationships with our customers, may deter future customers from purchasing our products and could expose us to costly litigation and settlement expenses. Even if we are not a party to any litigation between a customer and a third party relating to infringement by our products, an adverse outcome in any such litigation could make it more difficult for us to defend our products against intellectual property infringement claims in any subsequent litigation in which we are a named party. Any of these results could harm our brand and operating results.

Any intellectual property rights claim against us or our customers, suppliers, and channel partners, with or without merit, could be time-consuming, expensive to litigate or settle, could divert management resources and attention and could force us to acquire intellectual property rights and licenses, which may involve substantial royalty payments. Further, a party making such a claim, if successful, could secure a judgment that requires us to pay substantial damages. An adverse determination also could invalidate our intellectual property rights and prevent us from offering our products to our customers and may require that we procure or develop substitute products that do not infringe, which could require significant effort and expense. We may have to seek a license for the technology, which may not be available on reasonable terms or at all, may significantly increase our operating expenses or require us to restrict our business activities in one or more respects. Any of these events could seriously harm our business, operating results, and financial condition.

The success of our business depends in part on our ability to protect and enforce our intellectual property rights.

We rely on a combination of patent, copyright, service mark, trademark, and trade secret laws, as well as confidentiality procedures and contractual restrictions, to establish and protect our proprietary rights, all of which provide only limited protection. As of October 31, 2012, we had 32 issued patents and 114 patent applications in the United States and 107 corresponding patent applications in foreign countries. We cannot assure you that any patents will issue with respect to our currently pending patent applications in a manner that gives us the protection that we seek, if at all, or that any patents issued to us will not be challenged, invalidated, or circumvented. Our currently issued patents and any patents that may issue in the future with respect to pending or future patent applications may not provide sufficiently broad protection or they may not prove to be enforceable in actions against alleged infringers. We cannot be certain that the steps we have taken will prevent unauthorized use of our technology or the reverse engineering of our technology. Moreover, others may independently develop technologies that are competitive to ours or infringe our intellectual property.

Protecting against the unauthorized use of our intellectual property, products, and other proprietary rights is expensive and difficult. Litigation may be necessary in the future to enforce or defend our intellectual property rights or to determine the validity and scope of the proprietary rights of others. Any such litigation could result in substantial costs and diversion of management resources, either of which could harm our business, operating results, and financial condition. Further, many of our current and potential competitors have the ability to dedicate substantially greater resources to defending intellectual property infringement claims and to enforcing their intellectual property rights than we have. Accordingly, we may not be able to prevent third parties from infringing upon or misappropriating our intellectual property. Effective patent, trademark, service mark, copyright, and trade secret protection may not be available in every country in which our products are available. An inability to adequately protect and enforce our intellectual property and other proprietary rights could seriously harm our business, operating results, and financial condition.

Our use of open source and third-party technology could impose limitations on our ability to commercialize our software.

We use open source software in our products. Although we monitor our use of open source software closely, the terms of many open source licenses have not been interpreted by U.S. courts, and there is a risk that such licenses could be construed in a manner that imposes unanticipated conditions or restrictions on our ability to market our products. In such event, we could be required to seek licenses from third parties in order to continue offering our products for certain uses, to license portions of our source code at no charge, to re-engineer our technology or to discontinue offering some of our software in the event re-engineering cannot be accomplished on a timely basis, any of which could adversely affect our business, operating results, and financial condition.

- 37 -

We might require additional capital to support business growth, and this capital might not be available on acceptable terms, or at all.

We intend to continue to make investments to support our business growth and may require additional funds to respond to business challenges, including the need to develop new products or enhance our existing products, enhance our operating infrastructure and acquire complementary businesses and technologies. Accordingly, we may need to engage in equity or debt financings to secure additional funds. If we raise additional funds through further issuances of equity or convertible debt securities, our stockholders could suffer significant dilution, and any new equity securities we issue could have rights, preferences, and privileges superior to those of holders of our common stock. Any debt financing in the future could involve additional restrictive covenants relating to our capital raising activities and other financial and operational matters, which may make it more difficult for us to obtain additional capital and to pursue business opportunities, including potential acquisitions. We may not be able to obtain additional financing on terms favorable to us, if at all. If we are unable to obtain adequate financing or financing on terms satisfactory to us, when we require it, our ability to continue to support our business growth and to respond to business challenges could be significantly limited, and our business, operating results, financial condition, and prospects could be adversely affected.

If we do not successfully integrate our acquisition of IO Turbine, or if we do not otherwise achieve the expected benefits of the acquisition, our growth rate may decline and our operating results may be materially harmed.

In August 2011, we acquired IO Turbine, a provider of caching solutions for virtual environments, based in San Jose, California. If we fail to successfully integrate the business, operations, and technologies of IO Turbine, we may not realize the potential benefits of the acquisition. The integration of IO Turbine has resulted in the incurrence of ongoing expenses. If our integration effort is not successful, our results of operations could be harmed, employee morale could decline, key employees could leave, and customers could cancel existing orders or choose not to place new ones. Even if our integration efforts are successful, we may not achieve anticipated synergies or other benefits of the acquisition, including the anticipated benefits from the IO Turbine technology.

We may further expand through acquisitions of, or investments in, other companies, each of which may divert our management’s attention, resulting in additional dilution to our stockholders and consumption of resources that are necessary to sustain and grow our business.

Our business strategy may, from time to time, include acquiring other complementary products, technologies, or businesses. We also may enter into relationships with other businesses in order to expand our product offerings, which could involve preferred or exclusive licenses, additional channels of distribution or discount pricing or investments in other companies. Negotiating these transactions can be time-consuming, difficult, and expensive, and our ability to close these transactions may be subject to third-party approvals, such as government regulation, which are beyond our control. Consequently, we can make no assurance that these transactions, once undertaken and announced, will close.

These kinds of acquisitions or investments may result in unforeseen operating difficulties and expenditures. In particular, we may encounter difficulties assimilating or integrating the businesses, technologies, products, personnel, or operations of the acquired companies, particularly if the key personnel of the acquired business choose not to work for us, and we may have difficulty retaining the customers of any acquired business. Acquisitions may also disrupt our ongoing business, divert our resources and require significant management attention that would otherwise be available for development of our business. Any acquisition or investment could expose us to unknown liabilities. Moreover, we cannot assure you that the anticipated benefits of any acquisition or investment would be realized or that we would not be exposed to unknown liabilities. In connection with these types of transactions, we may issue additional equity securities that would dilute our stockholders, use cash that we may need in the future to operate our business, incur debt on terms unfavorable to us or that we are unable to repay, incur large charges or substantial liabilities, encounter difficulties integrating diverse business cultures, and become subject to adverse tax consequences, substantial depreciation or deferred compensation charges. These challenges related to acquisitions or investments could adversely affect our business, operating results, and financial condition.

Because our long-term success depends, in part, on our ability to expand the sales of our products to customers located outside of the United States, our business is susceptible to risks associated with international operations.

While we currently maintain limited operations outside of the United States, we have been expanding and intend to continue to expand these operations in the future. We have limited experience operating in foreign jurisdictions. Our inexperience in operating our business outside of the United States increases the risk that our international expansion efforts may not be successful. In addition, conducting and expanding international operations subjects us to new risks that we have not generally faced in the United States. These include: exposure to foreign currency exchange rate risk; difficulties in managing and staffing international operations; the increased travel, infrastructure, and legal compliance costs associated with multiple international locations; potentially adverse tax consequences; the burdens of complying with a wide variety of foreign laws, including trade barriers, and different legal standards; increased financial accounting and reporting burdens and complexities; political, social and economic instability abroad, terrorist attacks, and security concerns in general; and reduced or varied protection for intellectual property rights in some countries. The occurrence of any one of these risks could negatively affect our international business and, consequently, our business, operating results, and financial condition generally.

Adverse economic conditions or reduced datacenter spending may adversely impact our revenues and profitability.

Our operations and performance depend in part on worldwide economic conditions and the impact these conditions have on levels of spending on datacenter technology. Our business depends on the overall demand for datacenter infrastructure and on the economic health of our current and prospective customers. Weak economic conditions, or a reduction in datacenter spending, would likely adversely impact our business, operating results, and financial condition in a number of ways, including by reducing sales, lengthening sales cycles, and lowering prices for our products and services.

Governmental regulations affecting the import or export of products could negatively affect our revenue.

The U.S. and various foreign governments have imposed controls, export license requirements, and restrictions on the import or export of some technologies, especially encryption technology. In addition, from time to time, governmental agencies have proposed additional regulation of encryption technology, such as requiring the escrow and governmental recovery of private encryption keys. Governmental regulation of encryption technology and regulation of imports or exports, or our failure to obtain required import or export approval for our products, could harm our international and domestic sales and adversely affect our revenue. In addition, failure to comply with such regulations could result in penalties, costs, and restrictions on export privileges, which would harm our operating results.

The terms of our loan and security agreement with a financial institution may restrict our ability to engage in certain transactions.

Pursuant to the current terms of our loan and security agreement with a financial institution, we are subject to financial covenants and cannot engage in certain transactions, including disposing of certain assets, incurring additional indebtedness, declaring dividends, acquiring or merging with another entity or leasing additional real property unless certain conditions are met or unless we receive prior approval from the financial institution. The loan and security agreement further limits our ability to make material changes to our management team or enter into transactions with affiliates. If the financial institution does not consent to any of these actions or if we are unable to comply with these covenants, we could be prohibited from engaging in transactions which could be beneficial to our business and our stockholders.

Our business is subject to the risks of earthquakes and other natural catastrophic events, and to interruption by man-made problems such as computer viruses or terrorism.

Our two largest facilities and our current contract manufacturers are located in the San Francisco Bay and Salt Lake City areas, which have heightened risks of earthquakes. We may not have adequate business interruption insurance to compensate us for losses that may occur from a significant natural disaster, such as an earthquake, which could have a material adverse impact on our business, operating results and financial condition. In addition, acts of terrorism or malicious computer viruses could cause disruptions in our or our customers’ businesses or the economy as a whole. To the extent that these disruptions result in delays or cancellations of customer orders or the deployment of our products, our business, operating results, and financial condition would be adversely affected.

Failure to comply with governmental laws and regulations could harm our business.

Our business is subject to regulation by various federal, state, local, and foreign governmental agencies, including agencies responsible for monitoring and enforcing employment and labor laws, workplace safety, product safety, environmental laws, consumer protection laws, anti-bribery laws, import/export controls, federal securities laws and tax laws, and regulations. In certain jurisdictions, these regulatory requirements may be more stringent than in the United States. Noncompliance with applicable regulations or requirements could subject us to investigations, sanctions, mandatory product recalls, enforcement actions, disgorgement of profits, fines, damages, and civil and criminal penalties, or injunctions. If any governmental sanctions are imposed, or if we do not prevail in any possible civil or criminal litigation, our business, operating results, and financial condition could be materially adversely affected. In addition, responding to any action will likely result in a significant diversion of management’s attention and resources and an increase in professional fees. Enforcement actions and sanctions could harm our business, operating results, and financial condition.

Risks Related to Our Common Stock

The trading price of our common stock is likely to be volatile, and an active, liquid, and orderly market for our common stock may not be sustained.

Our common stock is currently traded on the New York Stock Exchange, but we can provide no assurance that there will be active trading on that market or any other market in the future. If there is not an active trading market or if the volume of trading is limited, the price of our common stock could decline and holders of our common stock may have difficulty selling their shares. In

- 39 -

addition, the trading price of our common stock may be highly volatile and could be subject to wide fluctuations in response to various factors, some of which are beyond our control. For example, after opening at $19.00 per share at the IPO, our common stock has experienced an intra-day trading high of $41.74 per share and a low of $14.90 per share through September 30, 2012. Some of the factors affecting our volatility include:

• price and volume fluctuations in the overall stock market from time to time;

• significant volatility in the market price and trading volume of technology companies in general, and of companies in our industry;

• actual or anticipated changes in our results of operations or fluctuations in our operating results;

• whether our operating results meet the expectations of securities analysts or investors;

• actual or anticipated changes in the expectations of investors or securities analysts;

• actual or anticipated developments in our competitors’ businesses or the competitive landscape generally;

• litigation involving us, our industry or both;

• regulatory developments in the United States, foreign countries or both;

• general economic conditions and trends;

• major catastrophic events;

• sales of large blocks of our stock; or

• departures of key personnel.

The stock markets in general, and market prices for the securities of technology-based companies like ours in particular, have from time to time experienced volatility that often has been unrelated to the operating performance of the underlying companies. A certain degree of stock price volatility can be attributed to being a newly public company. These broad market and industry fluctuations may adversely affect the market price of our common stock, regardless of our operating performance. In several recent situations where the market price of a stock has been volatile, holders of that stock have instituted securities class action litigation against the company that issued the stock. If any of our stockholders were to bring a lawsuit against us, the defense and disposition of the lawsuit could be costly and divert the time and attention of our management and harm our operating results.

If securities analysts do not publish research or reports about our business, or if they downgrade our stock, the price of our stock could decline.

The trading market for our common stock is likely to be influenced by any research and reports that securities or industry analysts publish about us or our business. In the event securities or industry analysts cover our company and one or more of these analysts downgrade our stock or publish inaccurate or unfavorable research about our business, our stock price would likely decline. If one or more of these analysts ceases coverage of our company or fails to publish reports on us regularly, demand for our stock could decrease, which could cause our stock price and trading volume to decline.

Insiders will continue to have substantial control over us, which could limit your ability to influence the outcome of key transactions, including a change of control.

As of October 31, 2012, our directors, executive officers, and each of our stockholders who own greater than 5% of our outstanding common stock and their affiliates, in the aggregate, own approximately 37% of the outstanding shares of our common stock. As a result, these stockholders, if acting together, could influence matters requiring approval by our stockholders, including the election of directors and the approval of mergers, acquisitions, or other extraordinary transactions. They may also have interests that differ from yours and may vote in a way with which you disagree and which may be adverse to your interests. This concentration of ownership may have the effect of delaying, preventing, or deterring a change of control of our company, could deprive our stockholders of an opportunity to receive a premium for their common stock as part of a sale of our company and might ultimately affect the market price of our common stock. In addition, the significant concentration of stock ownership may adversely affect the trading price of our common stock due to investors’ perception that conflicts of interest may exist or arise.

We have broad discretion in the use of the net proceeds that we received in our public offerings of common stock and may not use them effectively.

We have broad discretion in the application of the net proceeds from our public offerings of common stock in 2011 and could spend the proceeds in ways that do not improve our results of operations or enhance the value of our common stock. We have not allocated these net proceeds for any specific purposes. We might not be able to yield a significant return, if any, on any investment of these net proceeds. Stockholders will not have the opportunity to influence our management’s decisions on how to use the net proceeds, and our failure to apply the funds effectively could have a material adverse effect on our business, and could cause the price of our common stock to decline.

- 40 -

We have never paid dividends on our common stock and we do not anticipate paying any cash dividends in the foreseeable future.

We have never declared or paid any dividends on our common stock. In addition, our credit facility with a financial institution restricts our ability to pay dividends. We intend to retain any earnings to finance the operation and expansion of our business, and we do not anticipate paying any cash dividends in the future. As a result, you may only receive a return on your investment in our common stock if the market price of our common stock increases.

We will continue to incur increased costs as a result of being a public company.

As a public company, we are incurring and will continue to incur significant legal, accounting, and other expenses that we did not incur as a private company. In addition, new rules implemented by the SEC and the New York Stock Exchange, require changes in corporate governance practices of public companies. We expect these rules and regulations to continue to increase our legal and financial compliance costs and to make some activities more time-consuming and costly. We will continue to incur additional costs associated with our public company reporting requirements. We expect these rules and regulations to make it more difficult and more expensive for us to obtain director and officer liability insurance, and we may be required to accept reduced policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage. As a result, it may be more difficult for us to attract and retain qualified people to serve on our board of directors or as executive officers.

Provisions in our certificate of incorporation and bylaws and under Delaware law might discourage, delay, or prevent a change of control of our company or changes in our management and, therefore, depress the trading price of our common stock.

Our certificate of incorporation and bylaws contain provisions that could depress the trading price of our common stock by acting to discourage, delay, or prevent a change of control of our company or changes in our management that the stockholders of our company may deem advantageous. These provisions:

• establish a classified board of directors so that not all members of our board of directors are elected at one time;

• authorize the issuance of “blank check” preferred stock that our board of directors could issue to increase the number of outstanding shares to discourage a takeover attempt;

• prohibit stockholder action by written consent, which requires all stockholder actions to be taken at a meeting of our stockholders;

• prohibit stockholders from calling a special meeting of our stockholders;

• provide that the board of directors is expressly authorized to make, alter, or repeal our bylaws; and

• establish advance notice requirements for nominations for elections to our board of directors or for proposing matters that can be acted upon by stockholders at stockholder meetings.

Additionally, we are subject to Section 203 of the Delaware General Corporation Law, which generally prohibits a Delaware corporation from engaging in any of a broad range of business combinations with any “interested” stockholder for a period of three years following the date on which the stockholder became an “interested” stockholder and which may discourage, delay, or prevent a change of control of our company.

Any provision of our certificate of incorporation or bylaws or Delaware law that has the effect of delaying or deterring a change in control could limit the opportunity for our stockholders to receive a premium for their shares of our common stock, and could also affect the price that some investors are willing to pay for our common stock.

Part II. Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

Use of Proceeds from Registered Securities

Our initial public offering of common stock, or IPO, was made pursuant to a registration statement on Form S-1 (File No. 333-172683), which the SEC declared effective on June 8, 2011. In the offering, we issued and sold 12,600,607 shares, including 1,845,000 shares sold pursuant to the full exercise by the underwriters of their over-allotment option, at an issuance price of $19.00 per share. The offering did not terminate until after the sale of all of the securities registered by the registration statement. Goldman, Sachs & Co. and Morgan Stanley & Co. LLC acted as lead joint book-runners for the offering, and J.P. Morgan Securities LLC and Credit Suisse Securities (USA) LLC acted as passive joint book-runners. As a result of the offering, we raised approximately $218.9 million in proceeds, net of underwriting discounts, commissions and offering expenses.

- 41 -

During the three months ended September 30, 2011, we used approximately $17.6 million (net of cash acquired) of the net IPO proceeds to acquire IO Turbine.

Fair Value Measurements

3. Fair Value Measurements

Assets Measured and Recorded at Fair Value on a Recurring Basis

The Company measures and records certain financial assets at fair value on a recurring basis. Fair value is based on the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.

The Company’s financial instruments that are measured at fair value on a recurring basis consist of money market funds. The following three levels of inputs are used to measure the fair value of financial instruments:

Level 1:	Quoted prices in active markets for identical assets or liabilities. The Company classifies its money market funds as Level 1 instruments as they are traded in active markets with sufficient volume and frequency of transactions.
Level 2:	Observable prices that are based on inputs not quoted on active markets, but corroborated by market data.
Level 3:	Unobservable inputs are used when little or no market data is available.

The fair value of the Company’s money market funds was as follows (in thousands):

	Fair Value Measurements at June 30, 2012
Description	Level 1		Level 2		Level 3		Total
Cash equivalents:
Money market funds	$	266,944	$	—	$	—	$	266,944

Fair Value of Other Financial Instruments

The carrying amounts of the Company’s accounts receivable, accounts payable, accrued liabilities, and other liabilities approximate their fair values due to their short maturities.

Description of Business and Summary of Significant Accounting Policies

1. Description of Business and Summary of Significant Accounting Policies

Fusion-io, Inc. (the “Company” or “Fusion-io”) provides an enterprise storage memory platform, based on the Company’s ioMemory technology with VSL storage virtualization software, automated data-tiering and virtualization caching software, datacenter management software, ION Data Accelerator software, and storage memory programming software. The Company was originally incorporated in the state of Nevada in December 2005 and in June 2010 was reincorporated in the state of Delaware as Fusion-io, Inc. The Company sells its products and services through its global direct sales force, original equipment manufacturers (“OEMs”), and other channel partners.

Basis of Presentation

The accompanying condensed consolidated balance sheets and the condensed consolidated statements of operations, comprehensive income, and cash flows are unaudited. These unaudited interim condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) on the same basis as the audited consolidated financial statements and, in the opinion of management, reflect all adjustments (all of which are considered of a normal recurring nature) considered necessary to present fairly the Company’s financial position, results of operations, and cash flows. The results of operations for the three months ended September 30, 2012 are not necessarily indicative of the results that may be expected for the full fiscal year ending June 30, 2013 or any other period.

These unaudited interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended June 30, 2012 (the “2012 Annual Report”) filed with the Securities and Exchange Commission (the “SEC”).

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

Segment and Geographic Information

Operating segments are defined in accounting standards as components of an enterprise about which separate financial information is available and is regularly evaluated by management, namely the chief operating decision maker of an organization, in order to make operating and resource allocation decisions. The Company has concluded it operates in one business segment, which is the development, marketing, and sale of storage memory platforms. Substantially all of the Company’s revenue for all periods presented in the accompanying condensed consolidated statements of operations has been from sales of the ioDrive product lines and related customer support services. The Company’s headquarters and most of its operations are located in the United States; however, it conducts sales activities through sales offices in Europe and Asia. Revenue recognized from sales with a ship-to location outside of the United States was 29% and 38% of revenue for the three months ended September 30, 2011 and 2012, respectively. Revenue recognized from sales to customers with a ship-to address in Puerto Rico was 11% of revenue for the three months ended September 30, 2011 and revenue recognized from sales to customers with a ship-to address in Germany was 19% of revenue for the three months ended September 30, 2012. No other country outside of the United States accounted for 10% or more of revenue for all periods presented. Long-lived assets located outside of the United States were not material for all periods for which a condensed consolidated balance sheet is presented.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. On an on-going basis, the Company evaluates its significant estimates, including those related to revenue recognition, sales returns, accounting for business combinations and impairment of long-lived and intangible assets including goodwill, determination of fair value of stock options, valuation of inventory, product warranty, and income taxes. The Company also uses estimates in determining the useful lives of property and equipment and intangible assets and provisions for doubtful accounts. Actual results could differ from those estimates.

Significant Customers

Customers that accounted for 10% or more of the Company’s revenue represented 68% and 70% of revenue for the three months ended September 30, 2011 and 2012, respectively. As a result of the concentration of the Company’s customers, and typically a small number of large purchases by these customers, revenue, gross margin, and operating results may fluctuate significantly from period to period.

Product Warranty

The Company provides its customers a standard limited product warranty of up to five years. The standard warranty requires the Company to repair or replace defective products at no cost to the customer during such warranty period. The Company estimates the costs that may be incurred under its standard limited warranty and records a liability in the amount of such costs at the time product sales are recognized. Factors that affect the Company’s warranty liability include the number of installed units, identified warranty issues, historical experience, and management’s judgment regarding anticipated rates of warranty claims and cost per claim. The Company assesses the adequacy of its recorded warranty liability each period and makes adjustments to the liability as necessary based on actual experience.

The following table presents the changes in the product warranty liability (in thousands):

	Total
Balance at June 30, 2012	$	2,825
Warranty costs accrued		359
Warranty claims		(522	)
Balance at September 30, 2012	$	2,662

Warranty costs accrued includes amounts accrued for products at the time of shipment, adjustments for changes in estimated costs for warranties on products shipped in the period, and changes in estimated costs for warranties on products shipped in prior periods. It is not practicable to determine the amounts applicable to each of these components.

Net Income Per Share

Basic net income per share is computed using the weighted-average number of common shares outstanding during the period, less weighted-average common shares subject to repurchase. Diluted net income per share is computed using the weighted-average number of common shares outstanding and potentially dilutive common shares outstanding during the period that have a dilutive effect on net income per share. Potentially dilutive common shares result from the assumed exercise of outstanding stock options, common stock warrants, restricted stock awards, restricted stock units, and the assumed vesting of outstanding restricted stock subject to vesting provisions. In a net loss position, diluted net loss per share is computed using only the weighted-average number of common shares outstanding during the period, less weighted-average common shares subject to repurchase, as any additional common shares would be anti-dilutive.

The following table presents the reconciliation of the numerator and denominator used in the calculation of basic and diluted net income per share (in thousands):

	Three Months Ended September 30,
	2011			2012
Numerator:
Net income	$	7,189		$	3,933
Denominator:
Weighted-average common shares outstanding		82,232			94,432
Less weighted-average common shares outstanding subject to repurchase		(224	)		(211	)
Weighted-average shares, basic		82,008			94,221
Effect of dilutive securities		21,446			14,204
Weighted-average shares, diluted		103,454			108,425

The computation of diluted net income per common share for the three months ended September 30, 2011 and 2012 excluded common stock equivalents of 3,803,000 and 6,504,577, respectively, as their impact was anti-dilutive.

Recently Issued and Adopted Accounting Pronouncements

In June 2011, the FASB issued new guidance which improves the comparability, consistency, and transparency of financial reporting and increases the prominence of items reported in other comprehensive income (“OCI”) by eliminating the option to present components of OCI as part of the statement of changes in stockholders’ equity. The amendments in this standard require that all nonowner changes in stockholders’ equity be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements. Subsequently in December 2011, the FASB issued additional guidance, which indefinitely defers the requirement to present on the face of the financial statements reclassification adjustments for items that are reclassified from OCI to net income in the statement where the components of net income and the components of OCI are presented. The amendments in these standards do not change the items that must be reported in OCI, when an item of OCI must be reclassified to net income, or change the option for an entity to present components. The Company adopted this guidance retrospectively in the first quarter of fiscal year 2013. The adoption of this guidance did not have an impact on the Company’s results of operations, financial position, or cash flows as it related only to financial statement presentation.

Loan and Security Agreement

In September 2010, the Company amended and restated its loan and security agreement (the “Revolving Line of Credit”) with a financial institution. The Revolving Line of Credit allows the Company to borrow up to a limit of $25,000,000. A sublimit of $6,000,000 for letters of credit, certain cash management services, and foreign exchange forward contracts applied until May 2012. The total balance of letters of credit outstanding at September 30, 2012 was $3,183,000, which reduces the amount the Company has available to borrow under the Revolving Line of Credit. Prior to May 2012, borrowings under the Revolving Line of Credit would have accrued interest at a floating per annum rate equal to one-half of one percentage point (0.50%) above the prime rate as published in the Wall Street Journal. An unused commitment fee equal to 0.375% of the difference between the $25,000,000 limit and the average daily balance of borrowings outstanding each quarter was due on the last day of such quarter. Prior to May 2012, the Revolving Line of Credit was secured by substantially all of the Company’s assets. The Company can make advances against the Revolving Line of Credit until its maturity date, at which time all unpaid principal and interest shall be due and payable.

In August 2011, the Company entered into an amendment to the Revolving Line of Credit which provided for the consent of the financial institution with respect to the acquisition of IO Turbine and certain amendments to provide the Company with further flexibility to consummate mergers and acquisitions permitted under the Revolving Line of Credit.

In May 2012, the Company entered into a second amendment to the Revolving Line of Credit. Pursuant to this amendment, the pricing on revolving line of credit was amended such that borrowings under the Revolving Line of Credit accrue interest at a per annum rate equal to, at the Company’s option, a floating per annum rate equal to the prime rate as published in the Wall Street Journal, or the LIBOR rate (based on 1, 2, 3 or 6-month interest periods) plus a margin equal to two percent (2.00%) per annum. This amendment further provides for, among other things, (i) the reduction of the quarterly unused commitment fee to an amount equal to one-quarter of one percent (0.25%) per annum of the difference between the $25,000,000 loan commitment and the average daily balance of borrowings outstanding on the last day of each quarter, (ii) the removal of the borrowing base formula and the sublimit restricting the issuance of letters of credit, cash management services and foreign exchange forward contracts, and (iii) the release of the financial institution’s security interest in all of the Company’s assets.

Under the terms of the Revolving Line of Credit, the Company is required to maintain the following minimum financial covenants on a consolidated basis:

• A ratio of current assets to current liabilities plus, without duplication, any of the Company’s obligations to the financial institution, of at least 1.25 to 1.00.

• A tangible net worth of at least $25,000,000, plus 25% of the net proceeds the Company received from the sale or issuance of its equity or subordinated debt, such increase to be measured as of the last day of the quarter in which the Company received such proceeds.

In September 2012, the Company entered into a third amendment to the Revolving Line of Credit. Pursuant to this amendment, the maturity date of the Revolving Line of Credit was extended to December 2012.

As of September 30, 2012, no borrowings were outstanding under the Revolving Line of Credit and the Company was in compliance with all covenants.

Letters of Credit

As of June 30, 2012 and September 30, 2012, the Company had a total of $3,183,000 in letters of credit outstanding with a financial institution. These outstanding letters of credit have been issued for purposes of securing the Company’s obligations under facility leases.

Leases

Future minimum lease payments under non-cancelable operating leases were as follows (in thousands):

Fiscal Year Ended June 30,	Operating Leases
Remaining 2013	$	4,405
2014		5,618
2015		6,015
2016		6,150
2017		6,228
Thereafter		23,844
Total	$	52,260

Operating lease payments primarily relate to the Company’s leases of office space with various expiration dates through 2021. The terms of these leases often include periods of free rent, or rent holidays, and increasing rental rates over time. The Company recognizes rent expense on a straight-line basis over the lease period and has accrued for rent expense recorded but not paid.

The Company also leases certain equipment under operating leases that expire at various dates through 2016. These equipment leases typically include provisions that allow the Company at the end of the initial lease term to renew the lease, purchase the underlying equipment at the then fair market value, or return the equipment to the lessor.

Rent expense was $982,000 and $1,741,000 for the three months ended September 30, 2011 and 2012, respectively.

Purchase Commitments

In May 2012, the Company entered into a minimum purchase commitment for raw materials inventory that ends in June 2013 and provides for a termination fee based on a percentage of the amount of raw materials inventory not taken under the commitment. As of September 30, 2012, approximately $21,545,000 remained outstanding under this commitment.

Indemnification

The Company has agreed to indemnify its officers and directors for certain events or occurrences, while the officer or director is or was serving at the Company’s request in such capacity. The maximum amount of potential future indemnification is unlimited; however, the Company has a director and officer insurance policy that provides corporate reimbursement coverage that limits its exposure and enables it to recover a portion of any future amounts paid. The Company is unable to reasonably estimate the maximum amount that could be payable under these arrangements since these obligations are not capped but are conditional to the unique facts and circumstances involved. Accordingly, the Company has no liabilities recorded for these agreements as of June 30, 2012 and September 30, 2012.

Many of the Company’s agreements with channel partners and customers generally include certain provisions for indemnifying the channel partners and customers against liabilities if the Company’s products infringe a third party’s intellectual property rights. To date, the Company has not incurred any material costs as a result of such indemnification provisions and has not accrued any liabilities related to such obligations in the condensed consolidated financial statements.

Employee Agreements

The Company has various agreements with selected employees pursuant to which if their employment is terminated by the Company without cause or by the employees for good reason, or following a change of control of the Company, the employees are entitled to receive certain benefits, including severance payments, accelerated vesting of stock and stock options, and certain insurance benefits.

Legal Matters

The Company is subject to legal proceedings and claims arising in the ordinary course of business, including claims of alleged infringement of third-party intellectual property rights. With respect to certain of these matters, the Company’s third-party suppliers have agreed to indemnify and defend the Company.

On September 7, 2011, Solid State Storage Solutions, Inc. filed a lawsuit in U.S. District Court for the Eastern District of Texas against the Company and eight other companies. The complaint alleges that the Company’s products infringe U.S. Patent Nos. 6,701,471; 7,234,087; 7,721,165; 6,370,059; 7,366,016; 7,746,697; 7,616,485; 6,341,085; 6,567,334; 6,347,051; 7,064,995; and 7,327,624. The complaint seeks both damages and a permanent injunction against the Company. The Company has limited information about the specific infringement allegations, but based on its preliminary investigation of the patents identified in the complaint, the Company does not believe that its products infringe any valid or enforceable claim of these patents. The Court has set a schedule calling for a patent claim construction hearing on January 9, 2013, and a trial commencing on July 1, 2013.

No amount has been accrued or disclosed as of September 30, 2012, as the Company has determined that an unfavorable resolution is either not currently probable or that an amount or relevant range is not reasonably estimable. However, litigation is inherently unpredictable and it is possible that a loss may occur related to the aforementioned lawsuit. Any unfavorable resolution of any of these matters could materially affect the Company’s consolidated financial position, cash flows, or results of operations. All legal costs associated with litigation are expensed as incurred.

Income Taxes

Income Taxes

7. Income Taxes

        In order to determine the quarterly provision for income taxes, the Company considers the estimated annual effective tax rate, which is based on expected annual income and statutory tax rates in the various jurisdictions in which the Company operates. To the extent that application of the estimated annual effective tax rate is not representative of the quarterly portion of actual tax expense expected to be recorded for the year, the Company determines the quarterly provision for income taxes based on actual year-to-date income. Certain significant or unusual items are separately recognized in the quarter during which they occur and can be a source of variability in the effective tax rates from quarter to quarter.

The components of the Company income tax expense or benefit include state income taxes, foreign income taxes, U.S. federal alternative minimum tax, and effects of stock-based awards. Income tax benefit was approximately $1,726,000 and income tax expense was approximately $4,571,000 for the three months ended September 30, 2011 and 2012, respectively, or approximately a benefit of 32% and an expense of 54% of income before income taxes, respectively. The Company’s effective tax rate for the three months ended September 30, 2012 is higher when compared to the same period in the prior year primarily due to the income tax benefit recorded in the prior year as a result of a valuation allowance reversal related to deferred tax liabilities generated from the acquisition of IO Turbine. In addition, the prior year taxable income was substantially offset by net operating losses which are no longer available to offset income tax expense in the current year. The effective tax rate for the three months ended September 30, 2012 differs from the U.S. federal statutory rate of 35% primarily due to the Company’s full valuation allowance against its net deferred tax assets, the tax effect of stock-based awards, as well as foreign and state tax expense.

The Company files U.S., state, and foreign income tax returns in jurisdictions with various statutes of limitations. The Company’s consolidated federal tax return and any significant state or foreign tax returns are not currently under examination.

The Company is subject to income taxes in various U.S. and foreign jurisdictions and to continual examination by tax authorities. Significant judgment is required in evaluating the Company’s uncertain tax positions and determining its provision for income taxes. During the three months ended September 30, 2012, the aggregate change in the total gross amount of unrecognized tax benefits was as follows (in thousands):

	Total
Balance at June 30, 2012	$	2,709
Decrease of unrecognized tax benefits taken in prior years		(39	)
Increase in unrecognized tax benefits related to current year		405
Balance at September 30, 2012	$	3,075

The Company recognizes interest and penalties related to uncertain tax positions as a component of income tax expense. The Company did not incur any material interest or penalties related to income taxes in any of the periods presented. The total amount of unrecognized tax benefits that, if recognized, would affect the effective tax rate is approximately $715,000. The Company does not anticipate any significant change of its uncertain tax positions within fiscal year 2013, and the Company does not anticipate any events which could cause a change to these uncertainties.

As of September 30, 2012, the Company had federal net operating loss carryforwards of $204,655,000, of which $201,520,000 relate to stock option deductions claimed for tax purposes greater than the deductions claimed for book purposes. As of September 30, 2012, the Company had state net operating loss carryforwards of $176,306,000, of which $161,996,000 relate to stock option deductions claimed for tax purposes greater than the deductions claimed for book purposes. Additionally, the Company had federal research and development tax credit carryforwards of $2,543,000, of which $2,492,000 relate to stock option deductions claimed for tax purposes greater than the deductions claimed for book purposes. The Company had state research and development tax credit carryforwards of $2,412,000, of which $537,000 related to stock option deductions claimed for tax purposes greater than the deductions claimed for book purposes. In the future, the Company intends to utilize any carryforwards available to reduce its tax payments.

The Company recorded directly to equity a tax benefit for the three months ended September 30, 2012 of approximately $4,385,000 related to certain tax deductions for stock-based awards.

Equity Incentive Plans

On July 1, 2012, the number of authorized shares of common stock available for issuance under the 2011 Equity Incentive Plan (the “2011 Plan”) was increased by 4,681,423 shares in accordance with the provisions of the 2011 Plan. At September 30, 2012, a total of 11,409,895 shares of common stock were available for grant under the Company’s equity incentive plans.

Stock option activity for all the Equity Incentive Plans for the three months ended September 30, 2012 was as follows:

	Number of Shares Subject to Outstanding Options			Weighted- Average Exercise Price Per Share		Weighted- Average Contractual Term (in Years)		Aggregate Intrinsic Value (1)

(1) The aggregate intrinsic value is equal to the difference between the exercise price of the underlying stock option awards and the fair value of the Company’s common stock as of September 30, 2012.

Employee Stock Options

Additional per share information related to stock options granted to employees was as follows:

	Three Months Ended September 30,

Weighted-average grant date fair value — granted	$	10.86	$	15.42
Weighted-average grant date fair value — assumed in connection with the acquisition of IO Turbine		27.31		—
Weighted-average grant date fair value — forfeited		9.08		11.06

The aggregate intrinsic value of stock options exercised during the three months ended September 30, 2011 and 2012 was approximately $2,086,000 and $41,576,000, respectively, which reflected the difference between the exercise prices of the underlying stock option awards and the fair value of the Company’s common stock on the date of exercise.

The Company recorded stock-based compensation expense related to employee stock options of approximately $2,443,000 and $5,093,000 for the three months ended September 30, 2011 and 2012, respectively. As of September 30, 2012, there was approximately $53,569,000 of total unrecognized compensation expense related to unvested stock options, which is expected to be recognized over a weighted-average service period of 2.8 years.

The Company estimates the fair value of stock options granted to employees using the Black-Scholes-Merton pricing model and a single option award approach, which requires the input of several highly subjective and complex assumptions. The risk-free interest rate for the expected term of the option is based on the yield available on United States Treasury Zero Coupon issues with an equivalent expected term. The expected option term used in the Black-Scholes-Merton pricing model is calculated using the simplified method. The simplified method defines the expected term as the average of the option’s contractual term and the option’s weighted-average vesting period. The Company utilizes this method as it has limited historical stock option data that is sufficient to derive a reasonable estimate of the expected stock option term. The computation of estimated expected volatility is based on the volatility of comparable companies from a representative peer group selected based on industry data.

The following table presents the assumptions used in the Black-Scholes-Merton pricing model related to employee stock options:

	Three Months Ended September 30,
	2011	2012
Expected volatility	59.1–59.9%	61.4–63.1%
Expected term (in years)	5.2–6.6	4.5–5.4
Risk-free interest rate	1.2–2.0%	0.6–0.7%
Expected dividends	—	—

Non-employee Stock Options

The Company from time to time grants options to purchase common stock to non-employees for advisory and consulting services. The Company estimates the fair value of these stock options using the Black-Scholes-Merton option pricing formula at each balance sheet date and records expense ratably over the vesting period of each stock option award. The Company recorded stock-based compensation expense related to these non-employee stock options of approximately $1,742,000 and $2,748,000 for the three months ended September 30, 2011 and 2012, respectively.

The following table presents the assumptions used in the Black-Scholes-Merton pricing model related to non-employee stock options:

	Three Months Ended September 30,
	2011	2012
Expected volatility	59.7–61.9%	61.2–61.8%
Expected term (in years)	7.1–9.7	6.1–8.7
Risk-free interest rate	1.9–2.4%	1.3–1.7%

Restricted Stock Units and Restricted Stock Awards

The following table summarizes activity during the three months ended September 30, 2012 related to restricted stock units (“RSUs”) and RSAs:

	Number of Shares			Weighted-Average Grant-Date Fair Value
Unvested RSUs and RSAs at June 30, 2012		1,957,566		$	24.17
Granted		860,310			27.15
Vested		(169,229	)		23.94
Forfeited		(4,965	)		28.40
Cancelled		(19,351	)		24.25
Unvested RSUs and RSAs at September 30, 2012		2,624,331		$	25.15

The Company recorded stock-based compensation expense related to RSUs and RSAs of approximately $5,270,000 and $5,344,000 for the three months ended September 30, 2011 and 2012, respectively. Of the stock-based compensation expense recognized during the three months ended September 30, 2011, approximately $3,795,000 was due to accelerated vesting of certain RSAs assumed in connection with the IO Turbine acquisition, of which, approximately $793,000 related to awards that were settled in cash at the time of acquisition. At September 30, 2012, there was approximately $60,812,000 of total unrecognized compensation cost related to unvested RSUs and RSAs. This unrecognized compensation cost is equal to the fair value of RSUs and RSAs expected to vest and will be recognized over a weighted-average period of 3.4 years.

Repurchases of Vested Restricted Stock Units

The Company is required to withhold minimum statutory taxes related to the vesting of RSUs, including the forfeiting of a portion of the newly vested award that has a current value equal to the withholding obligation. The Company is then required to remit the amount of taxes owed by the employee to the appropriate taxing authority. As a result of such forfeitures, during the three months ended September 30, 2012, the Company effectively repurchased a total of 43,392 shares of common stock related to employee tax withholding obligations. The Company has recorded approximately $1,055,000 as a financing activity for these forfeitures in the condensed consolidated statement of cash flows for the three months ended September 30, 2012. There were no repurchases of vested restricted stock units during the three months ended September 30, 2011.

Employee Stock Purchase Plan

The Company recorded stock-based compensation expense related to its 2011 Employee Stock Purchase Plan (“ESPP”) of approximately $321,000 and $704,000 for the three months ended September 30, 2011 and 2012, respectively. On July 1, 2012, the number of authorized shares available for issuance under the ESPP was increased by 936,284 shares in accordance with the provisions of the ESPP. During the three months ended September 30, 2012, the Company issued 158,241 shares of common stock under the ESPP. At September 30, 2012, a total of 1,129,105 shares of common stock were reserved for future issuance under the ESPP.

Description of Business and Summary of Significant Accounting Policies (Policies)

3 Months Ended

Sep. 30, 2012

Basis of Presentation

Basis of Presentation

The accompanying condensed consolidated balance sheets and the condensed consolidated statements of operations, comprehensive income, and cash flows are unaudited. These unaudited interim condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) on the same basis as the audited consolidated financial statements and, in the opinion of management, reflect all adjustments (all of which are considered of a normal recurring nature) considered necessary to present fairly the Company’s financial position, results of operations, and cash flows. The results of operations for the three months ended September 30, 2012 are not necessarily indicative of the results that may be expected for the full fiscal year ending June 30, 2013 or any other period.

These unaudited interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended June 30, 2012 (the “2012 Annual Report”) filed with the Securities and Exchange Commission (the “SEC”).

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

Segment and Geographic Information

Segment and Geographic Information

Operating segments are defined in accounting standards as components of an enterprise about which separate financial information is available and is regularly evaluated by management, namely the chief operating decision maker of an organization, in order to make operating and resource allocation decisions. The Company has concluded it operates in one business segment, which is the development, marketing, and sale of storage memory platforms. Substantially all of the Company’s revenue for all periods presented in the accompanying condensed consolidated statements of operations has been from sales of the ioDrive product lines and related customer support services. The Company’s headquarters and most of its operations are located in the United States; however, it conducts sales activities through sales offices in Europe and Asia. Revenue recognized from sales with a ship-to location outside of the United States was 29% and 38% of revenue for the three months ended September 30, 2011 and 2012, respectively. Revenue recognized from sales to customers with a ship-to address in Puerto Rico was 11% of revenue for the three months ended September 30, 2011 and revenue recognized from sales to customers with a ship-to address in Germany was 19% of revenue for the three months ended September 30, 2012. No other country outside of the United States accounted for 10% or more of revenue for all periods presented. Long-lived assets located outside of the United States were not material for all periods for which a condensed consolidated balance sheet is presented.

Use of Estimates

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. On an on-going basis, the Company evaluates its significant estimates, including those related to revenue recognition, sales returns, accounting for business combinations and impairment of long-lived and intangible assets including goodwill, determination of fair value of stock options, valuation of inventory, product warranty, and income taxes. The Company also uses estimates in determining the useful lives of property and equipment and intangible assets and provisions for doubtful accounts. Actual results could differ from those estimates.

Significant Customers

Significant Customers

Customers that accounted for 10% or more of the Company’s revenue represented 68% and 70% of revenue for the three months ended September 30, 2011 and 2012, respectively. As a result of the concentration of the Company’s customers, and typically a small number of large purchases by these customers, revenue, gross margin, and operating results may fluctuate significantly from period to period.

Product Warranty

Product Warranty

The Company provides its customers a standard limited product warranty of up to five years. The standard warranty requires the Company to repair or replace defective products at no cost to the customer during such warranty period. The Company estimates the costs that may be incurred under its standard limited warranty and records a liability in the amount of such costs at the time product sales are recognized. Factors that affect the Company’s warranty liability include the number of installed units, identified warranty issues, historical experience, and management’s judgment regarding anticipated rates of warranty claims and cost per claim. The Company assesses the adequacy of its recorded warranty liability each period and makes adjustments to the liability as necessary based on actual experience.

The following table presents the changes in the product warranty liability (in thousands):

	Total
Balance at June 30, 2012	$	2,825
Warranty costs accrued		359
Warranty claims		(522	)
Balance at September 30, 2012	$	2,662

Warranty costs accrued includes amounts accrued for products at the time of shipment, adjustments for changes in estimated costs for warranties on products shipped in the period, and changes in estimated costs for warranties on products shipped in prior periods. It is not practicable to determine the amounts applicable to each of these components.

Net Income Per Share

Net Income Per Share

Basic net income per share is computed using the weighted-average number of common shares outstanding during the period, less weighted-average common shares subject to repurchase. Diluted net income per share is computed using the weighted-average number of common shares outstanding and potentially dilutive common shares outstanding during the period that have a dilutive effect on net income per share. Potentially dilutive common shares result from the assumed exercise of outstanding stock options, common stock warrants, restricted stock awards, restricted stock units, and the assumed vesting of outstanding restricted stock subject to vesting provisions. In a net loss position, diluted net loss per share is computed using only the weighted-average number of common shares outstanding during the period, less weighted-average common shares subject to repurchase, as any additional common shares would be anti-dilutive.

The following table presents the reconciliation of the numerator and denominator used in the calculation of basic and diluted net income per share (in thousands):

	Three Months Ended September 30,
	2011			2012
Numerator:
Net income	$	7,189		$	3,933
Denominator:
Weighted-average common shares outstanding		82,232			94,432
Less weighted-average common shares outstanding subject to repurchase		(224	)		(211	)
Weighted-average shares, basic		82,008			94,221
Effect of dilutive securities		21,446			14,204
Weighted-average shares, diluted		103,454			108,425

The computation of diluted net income per common share for the three months ended September 30, 2011 and 2012 excluded common stock equivalents of 3,803,000 and 6,504,577, respectively, as their impact was anti-dilutive.

Recently Issued and Adopted Accounting Pronouncements

Recently Issued and Adopted Accounting Pronouncements

In June 2011, the FASB issued new guidance which improves the comparability, consistency, and transparency of financial reporting and increases the prominence of items reported in other comprehensive income (“OCI”) by eliminating the option to present components of OCI as part of the statement of changes in stockholders’ equity. The amendments in this standard require that all nonowner changes in stockholders’ equity be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements. Subsequently in December 2011, the FASB issued additional guidance, which indefinitely defers the requirement to present on the face of the financial statements reclassification adjustments for items that are reclassified from OCI to net income in the statement where the components of net income and the components of OCI are presented. The amendments in these standards do not change the items that must be reported in OCI, when an item of OCI must be reclassified to net income, or change the option for an entity to present components. The Company adopted this guidance retrospectively in the first quarter of fiscal year 2013. The adoption of this guidance did not have an impact on the Company’s results of operations, financial position, or cash flows as it related only to financial statement presentation.

Acquisitions

4. Acquisitions

On August 11, 2011, the Company acquired 100% of the stock of IO Turbine, Inc. (“IO Turbine”) pursuant to the Agreement and Plan of Reorganization (the “Merger Agreement”) dated August 4, 2011. IO Turbine was a provider of caching solutions for virtual environments, based in San Jose, California. Accordingly, the assets, liabilities, and operating results of IO Turbine are reflected in the Company’s condensed consolidated financial statements following the date of acquisition. The fair value of the aggregate purchase price was approximately $65,568,000, which consisted of (1) cash of approximately $21,199,000, (2) approximately $43,485,000 in common stock valued at $28.40 per share, the closing sale price of the Company’s common stock on the closing date of the acquisition, and (3) approximately $884,000 in assumed stock options attributable to pre-acquisition service. In addition, subsequent to the acquisition, the Company will recognize up to approximately $26,421,000 of stock-based compensation expense related to the fair value of assumed restricted stock awards (“RSAs”) and stock options, of which approximately $3,795,000 were expensed immediately in connection with the acceleration of vesting of certain restricted stock awards and the remainder will be recognized over the underlying future service period of the assumed stock awards and stock options. At the time of acquisition, IO Turbine stockholders holding RSAs had the option to receive cash and/or shares of the Company’s common stock for their unvested RSAs based on a fixed value determined at the acquisition date. As a result, the Company: (1) issued approximately 414,000 shares of its common stock that remain subject to forfeiture based on the original vesting schedule applicable to such awards and (2) will pay up to approximately $4,631,000 in cash in accordance with the original vesting schedule applicable to such awards. Of this total cash amount, approximately $2,407,000 had been paid through September 30, 2012.

For the three months ended September 30, 2011 and 2012, operating expenses associated with IO Turbine were approximately $6,443,000 and $3,056,000, respectively, of which approximately $5,261,000 and $2,269,000, respectively, related to stock-based compensation expense.
