NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 — THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

Company

Mellanox Technologies, Ltd. (the “Company” or “Mellanox”) was incorporated in Israel and commenced operations in March 1999. Mellanox is a supplier of high-performance semiconductor interconnect products for computing, storage and communications applications.

Principles of presentation

The unaudited condensed consolidated financial statements include the Company’s accounts as well as those of its wholly owned subsidiaries after the elimination of all significant intercompany balances and transactions.

The unaudited condensed consolidated financial statements included in this quarterly report on Form 10-Q have been prepared by the Company without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). The year-end unaudited condensed balance sheet data was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States. Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted pursuant to such rules and regulations. However, the Company believes that the disclosures contained in this quarterly report comply with the requirements of Section 13(a) of the Securities Exchange Act of 1934, as amended, for a quarterly report on Form 10-Q and are adequate to make the information presented not misleading. The unaudited condensed consolidated financial statements included herein reflect all adjustments (consisting of normal recurring adjustments) which are, in the opinion of management, necessary for a fair statement of the financial position, results of operations and cash flows for the interim periods presented. These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2012, filed with the SEC on February 25, 2013. The results of operations for the three and nine months ended September 30, 2013 are not necessarily indicative of the results to be anticipated for the entire year ending December 31, 2013 or thereafter.

Risks and uncertainties

The Company is subject to all of the risks inherent in a company which operates in the dynamic and competitive semiconductor industry. Significant changes in any of the following areas could have a material adverse impact on the Company’s financial position and results of operations: unpredictable volume or timing of customer orders; ordered product mix; the sales outlook and purchasing patterns of the Company’s customers based on consumer demands and general economic conditions; loss of one or more of the Company’s customers; decreases in the average selling prices of products or increases in the average cost of finished goods; the availability, pricing and timeliness of delivery of components used in the Company’s products; reliance on a limited number of subcontractors to manufacture, assemble, package and production test the Company’s products; the Company’s ability to successfully develop, introduce and sell new or enhanced products in a timely manner; product obsolescence and the Company’s ability to manage product transitions; and the timing of announcements or introductions of new products by the Company’s competitors.

Additionally, the Company has a significant presence in Israel, including research and development activities, corporate facilities and sales support operations. Uncertainty surrounding the political, economic and military conditions in Israel may directly impact the Company’s financial results.

Use of estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of net revenues and expenses in the reporting period. The Company regularly evaluates estimates and assumptions related to revenue recognition, allowances for doubtful accounts, sales returns and allowances, fair value of financial instruments, short-term investments, warranty reserves, inventory reserves, share-based compensation expense, long-term asset valuations, investments, goodwill and purchased intangible asset valuation, deferred income tax asset valuation allowances, uncertain

tax positions, litigation and other loss contingencies. These estimates and assumptions are based on current facts, historical experience and various other factors that the Company believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities and the recording of revenue, costs and expenses that are not readily apparent from other sources. The actual results the Company experiences may differ materially and adversely from its original estimates. To the extent there are material differences between the estimates and actual results, the Company’s future results of operations will be affected.

Significant accounting policies

There have been no changes in the Company’s significant accounting policies that were disclosed in its Annual Report on Form 10-K for the fiscal year ended December 31, 2012. See our Annual Report on Form 10-K for the year ended December 31, 2012, filed with the SEC on February 25, 2013, for a discussion of significant accounting policies and estimates.

Concentration of credit risk

The following table summarizes the revenues from customers (including original equipment manufacturers) in excess of 10% of the total revenues:

	Three Months EndedSeptember 30,				Nine Months EndedSeptember 30,
	2013		2012		2013		2012

The following table summarizes the accounts receivable balance in excess of 10% of the total accounts receivable:

	September 30,2013		December 31,2012
IBM	17	%	21	%

At September 30, 2013 and December 31, 2012, based on information filed with the SEC or reported to us, Oracle Corporation held approximately 3.8 million ordinary shares of Mellanox. Sales to Oracle mainly through its contract manufacturers in the three and nine months ended September 30, 2013 were $7.2 million and $22.0 million, respectively, and were conducted at arm’s-length. Sales to Oracle mainly through its contract manufacturers in the three and nine months ended September 30, 2012 were $8.0 million and $19.5 million, respectively, and were conducted at arm’s-length. At September 30, 2013 and December 31, 2012, accounts receivable from Oracle totaled $0.9 million and $0.2 million, respectively.

Product warranty

Changes in the Company’s liability for product warranty during the nine months ended September 30, 2013 and 2012 are included in Accrued liabilities and are as follows:

	Nine Months Ended September 30,

Net income (loss) per share

The following table sets forth the computation of basic and diluted net income (loss) per share for the periods indicated:

	Three Months EndedSeptember 30,					Nine Months EndedSeptember 30,
	2013			2012		2013			2012
	(in thousands except per share data)
Net income (loss)	$	(5,414	)	$	48,403	$	(15,610	)	$	92,938
Basic and diluted shares:
Weighted average ordinary shares outstanding used to compute basic net income (loss) per share	43,579			41,871		43,257			40,923
Dilutive effect of employee stock option plans	—			2,563		—			2,672
Shares used to compute diluted net income (loss) per share	43,579			44,434		43,257			43,595
Net income (loss) per share — basic	$	(0.12	)	$	1.16	$	(0.36	)	$	2.27
Net income (loss) per share — diluted	$	(0.12	)	$	1.09	$	(0.36	)	$	2.13

The Company excluded 1,066,286 and 772,885 outstanding shares for the three and nine months ended September 30, 2013, respectively, from the computation of diluted net income per ordinary share, because including these outstanding shares would have had an anti-dilutive effect.

The Company excluded 225,864 and 187,391 outstanding shares for the three and nine months ended September 30, 2012, respectively, from the computation of diluted net income per ordinary share, because including these outstanding shares would have had an anti-dilutive effect.

Recent accounting pronouncements

Effective January 1, 2013, the Company adopted the authoritative guidance, issued by the Financial Accounting Standards Board (“FASB”) in February 2013, related to reclassifications out of accumulated other comprehensive income (“OCI”). Under this guidance, an entity is required to report, in one place, information about reclassifications out of accumulated OCI and changes in its accumulated OCI balances. For significant items reclassified out of accumulated OCI to net income in their entirety in the same reporting period, reporting is required about the effect of the reclassifications on the respective line items in the statement where net income is presented. For items that are not reclassified to net income in their entirety in the same reporting period, a cross reference to other disclosures currently required under GAAP is required in the notes to the financial statements. The Company elected to present the information in the notes to the Company’s unaudited condensed consolidated financial statements. The adoption of this guidance had no impact on the Company’s consolidated financial statements.

In July 2013, the FASB issued authoritative guidance which requires that an unrecognized tax benefit, or portion of an unrecognized tax benefit, be presented as a reduction of a deferred tax asset for a net operating loss carryforward, a similar tax loss or a tax credit carryforward. If an applicable deferred tax asset is not available or a company does not expect to use the applicable deferred tax asset, the unrecognized tax benefit should be presented as a liability in the financial statements and should not be combined with an unrelated deferred tax asset. This guidance is effective for annual reporting periods, and interim periods within those years, beginning after December 15, 2013. The amendments should be applied prospectively to all unrecognized tax benefits that exist at the effective date; however, retrospective application is permitted. The Company will provide the required disclosures beginning in the first quarter of fiscal year 2014 and does not expect the adoption of this guidance to have a significant impact on its consolidated results of operations and financial condition.

NOTE 3 — BUSINESS COMBINATIONS:

On July 1, 2013, the Company completed its acquisition of a privately held company, IPtronics A/S (“IPtronics”). On August 15, 2013, the Company completed its acquisition of a privately held company, Kotura, Inc. (“Kotura”). The Company’s primary reasons for the IPtronics and Kotura acquisitions were to enhance its ability to deliver cost-effective, high-speed networks with next generation optical connectivity at 100 Gb/s and beyond. The acquisitions also enhanced the Company’s engineering team and added a strong patent portfolio in the field of silicon photonics.

The following table presents details of the purchase consideration related to each acquisition:

Company Acquired	Cash Consideration Paid		Cash Assumed		Net Cash Paid
	(in thousands)
IPtronics A/S	$	44,925	$	2,077	$	42,848
Kotura, Inc.	80,772		101		80,671
Total	$	125,697	$	2,178	$	123,519

10

In conjunction with the IPtronics acquisition, the Company issued 60,508 restricted stock units (“RSUs”) of the Company’s ordinary shares with an aggregate value of $3.0 million in exchange for RSUs of IPtronics. The fair value of the RSUs is based on the closing price of the Company’s ordinary shares on July 1, 2013 of $49.92. The RSU grants will result in compensation expense of $3.0 million which will be recognized over the vesting period of four years.

In conjunction with the Kotura acquisition, the Company issued options to purchase 31,653 shares of the Company’s ordinary shares and 145,425 RSUs of the Company’s ordinary shares with an aggregate value of $6.4 million, in exchange for options to purchase shares and RSUs of Kotura. This grant will result in compensation expense of $6.4 million which will be recognized over the remaining vesting period of these equity awards, which ranges from one day to four years.

The fair value of the exchanged options was determined using a Black-Scholes valuation model with the following weighted-average assumptions: expected life of 4.72 years, volatility of 57.5%, risk-free interest rate of 1.54%, and dividend yield of zero. The fair value of the exchanged RSUs was determined based on the per share value of the underlying Company ordinary shares of $42.19 per share at August 15, 2013.

The Company accounted for both transactions using the acquisition method, and accordingly, the consideration has been allocated to the tangible and intangible assets acquired and liabilities assumed on the basis of their respective estimated fair values on the respective acquisition date. The Company’s preliminary allocation of the total purchase price for each transaction is summarized below:

The preliminary estimates above are subject to change once the Company receives certain information it believes is necessary to finalize its determination of the fair value of assets acquired and liabilities assumed under the acquisition.

Identifiable intangible assets

Intangible assets acquired and their respective estimated remaining useful lives over which each asset will be amortized are:

	Fair value		Weighted Average Useful life
	(in thousands)		(in years)
Purchased intangible assets:
Licensed technology	$	135	6
Developed technology	27,827		5
In-process research and development	13,764		—
Customer relationship	2,420		1-2
Backlog	953		Less than 1
Total purchased intangible assets	$	45,099

Developed technology represents completed technology that has reached the technological feasibility and/or is currently offered for sale to customers. The Company used the income approach to value the developed technology. Under the income approach, the expected future cash flows from each technology are estimated and discounted to their net present values at an appropriate risk-adjusted rate of return. Significant factors considered in the calculation of the rate of return are the weighted average cost of capital

11

and the return on assets. The Company applied a discount rate of 17.5% for IPtronics and 15.5% for Kotura to value the developed technology assets taking into consideration market rates of return on debt and equity capital and the risk associated with achieving forecasted revenues related to these assets.

In-process research and development (“IPR&D”) represents projects that have not yet reached technological feasibility. Technological feasibility is defined as being equivalent to completion of a beta-phase working prototype in which there is no remaining risk relating to the development. As of the acquisition date, IPtronics was involved in research and development projects related to its laser-drivers, modulator-drivers, and trans-impedance-amplifier for 25 Gb/s, enabling fast communication at 4x25 Gb/s for interconnect solutions. Each of these products is focused on developing and later on integrating new technologies while broadening features and functionalities. There is a risk that these development efforts and enhancements will not be competitive with other products on cost and functionality.

As of the acquisition date, Kotura was involved in research and development projects related to its silicon photonics modulator for 25 Gb/s, enabling fast communication at 4x25 Gb/s and wavelength-division multiplexing “WDM” for interconnect products. Each of these products is focused on developing and later on integrating new technologies and broadening features and functionalities. There is a risk that these development efforts and enhancements will not be competitive with other products using alternative technologies that offer comparable functionality.

Upon successful completion of the development process for the acquired IPR&D projects, the assets will then be considered finite-lived intangible assets and amortization of the assets will commence. None of the projects has been completed as of September 30, 2013.

The following table summarizes the significant assumptions underlying the valuations of IPR&D at acquisition:

Company	Development Projects	Average Estimated time to complete	Estimated cost to complete		Risk Adjusted Discount Rate		Fair value
		(in months)	(in thousands)		(%)		(in thousands)
IPtronics	Modulator drivers - 4x25Gb/s	18	$	9,549	19.5	%	$	4,121
Kotura	Silicon photonics modulator - 4x25Gb/s	18	17,210		16.5	%	9,643
			$	26,759			$	13,764

Customer relationships represent the fair value of future projected revenues that will be derived from the sale of products to existing customers of the acquired company. The Company used the comparative method (“with/without”) of the income approach to determine the fair value of this intangible asset and utilized a discount rate of 15.5%.

Backlog represents the fair value of sales order backlog as of the valuation date. The Company used the income approach to determine the fair value of this intangible asset.

The goodwill arising from these acquisitions is primarily attributed to sales of future products and the assembled workforce. Goodwill is not deductible for tax purposes. Goodwill is not being amortized but is reviewed annually for impairment or more frequently if impairment indicators arise, in accordance with authoritative guidance.

The following table presents certain unaudited pro forma information for illustrative purposes only, for fiscal 2013 and fiscal 2012 as if IPtronics and Kotura had been acquired on January 1, 2012. The unaudited estimated pro forma information combines the historical results of IPtronics and Kotura with the Company’s consolidated historical results and includes certain adjustments reflecting the estimated impact of fair value adjustments for the respective periods. The pro forma information is not indicative of what would have occurred had the acquisitions taken place on January 1, 2012. Additionally, the pro forma financial information does not include the impact of possible business model changes between IPtronics, Kotura and the Company. The Company expects to achieve further business synergies, as a result of the acquisitions that are not reflected in the pro forma amounts that follow. As a result, actual results will differ from the unaudited pro forma information presented (in thousands, except per share data):

	Nine Months Ended September 30,

NOTE 4 — FAIR VALUE MEASUREMENTS:

Fair value hierarchy

The Company measures its cash equivalents and marketable securities at fair value. The Company’s cash equivalents are classified within Level 1. Cash equivalents are valued primarily using quoted market prices utilizing market observable inputs. The Company’s investments in debt securities and certificates of deposits are classified within Level 2 as the market inputs to value these instruments consist of market yields, reported trades and broker/dealer quotes. In addition, foreign currency contracts are classified within Level 2 as the valuation inputs are based on quoted prices and market observable data of similar instruments. The Level 3 valuation inputs include the Company’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. The inputs are unobservable in the market and significant to the instrument’s valuation. As of September 30, 2013 and December 31, 2012, the Company did not have any financial assets or liabilities valued based on Level 3 valuations.

The following table presents the fair value hierarchy of the Company’s financial assets measured at fair value as of September 30, 2013. There were no financial liabilities as of September 30, 2013.

NOTE 7 — DERIVATIVES AND HEDGING ACTIVITIES:

The Company uses derivative instruments primarily to manage exposures to foreign currency. The Company enters into forward contracts to manage its exposure to changes in the exchange rate of the New Israeli Shekel (“NIS”) against the U.S. dollar. The Company uses forward contracts designated as cash flow hedges to hedge a substantial portion of future forecasted operating expenses in NIS. The Company’s primary objective in entering into these arrangements is to reduce the volatility of earnings and cash flows associated with changes in foreign currency exchange rates. The program is not designated for trading or speculative purposes. The Company’s forward contracts expose the Company to credit risk to the extent that the counterparties may be unable to meet the terms of the agreement. The Company seeks to mitigate such risk by limiting its counterparties to major financial institutions and by spreading the risk across a number of major financial institutions. In addition, the potential risk of loss with any one counterparty resulting from this type of credit risk is monitored on an ongoing basis.

As of September 30, 2013, the Company had forward contracts in place that hedged future operating expenses of approximately 134.0 million NIS, or approximately $37.9 million based upon the exchange rate as of September 30, 2013. The forward contracts cover a substantial portion of future NIS denominated operating expenses that the Company expects to incur over the next twelve months.

The Company does not use derivative financial instruments for purposes other than cash flow hedges.

Fair value of derivative contracts

Fair value of derivative contracts as of September 30, 2013 and December 31, 2012 were as follows:

	Derivative Assets Reported in Other Current Assets				Derivative Liabilities Reported in Other Current Liabilities
	September 30, 2013		December 31, 2012		September 30, 2013		December 31, 2012

Total derivatives designated as hedging instruments	$	1,755	$	2,942	$	—	$	—

Effect of designated derivative contracts on accumulated other comprehensive income

The following table presents the balance of designated derivative contracts as cash flow hedges as of September 30, 2013 and December 31, 2012, and their impact on OCI for the nine months ended September 30, 2013 (in thousands):

December 31, 2012	$	2,942
Amount of gain recognized in OCI (effective portion)	3,531
Amount of gain reclassified from OCI to income (effective portion)	(4,718		)
September 30, 2013	$	1,755

Foreign exchange contracts designated as cash flow hedges relate primarily to operating expenses and the associated gains and losses are expected to be recorded in operating expenses when reclassified out of OCI. The Company expects to realize the accumulated OCI balance related to foreign exchange contracts within the next twelve months.

Effect of derivative contracts on the condensed consolidated statement of operations

The impact of derivative contracts on total operating expenses in the three and nine months ended September 30, 2013 and 2012 was as follows:

	Three Months Ended September 30,					Nine Months Ended September 30,

Purchase commitments

At September 30, 2013, the Company had non-cancelable purchase commitments of $52.9 million, of which $46.4 million is expected to be paid in the remainder of 2013 and $6.5 million in 2014 and beyond.

Legal proceedings

The Company considers all legal claims on a quarterly basis in accordance with GAAP and, based on known facts, assesses whether potential losses are considered reasonably possible, probable and estimable.

The Company makes a provision for a liability when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. These provisions are reviewed at least quarterly and adjusted to reflect the impacts of negotiations, settlements, rulings, advice of legal counsel and other information and events pertaining to a particular case. Unless otherwise specifically disclosed in this note, the Company has determined that no provision for liability nor disclosure is required related to any claim against us because: (a) there is not a reasonable possibility that a loss exceeding amounts already recognized (if any) may be incurred with respect to such claim; (b) a reasonably possible loss or range of loss cannot be estimated; or (c) such estimate is immaterial. All legal costs associated with litigation are expensed as incurred.

Litigation is inherently unpredictable. However, the Company believes that it has valid defenses with respect to the pending legal matters. It is possible, nevertheless, that the consolidated financial position, cash flows or results of operations could be negatively affected by an unfavorable resolution of one or more of such proceedings, claims or investigations.

Pending legal proceedings as of September 30, 2013 were as follows:

Avago Technologies Fiber (IP) Singapore Pte. Ltd.

In re Mellanox Technologies, Ltd. Securities Litigation

On February 7, February 14 and February 22, 2013, Mellanox Technologies, Ltd., the Company’s President and CEO, former CFO and CFO were sued in three separate legal complaints filed in the United States District Court for the Southern District of New York naming the Company and them each as defendants and respectively entitled, Patrick Barnicle, on behalf of himself and others similarly situated v. Mellanox Technologies, Ltd., Eyal Waldman, Michael Gray and Jacob Shulman, Case No. 13 CIV 925, David R. Ryan, Jr., on behalf of himself and others similarly situated v. Mellanox Technologies, Ltd., Eyal Waldman, Michael Gray and Jacob Shulman, Case No. 13 CV 1047 and Valentin Petrov, on behalf of himself and others similarly situated v. Mellanox Technologies, Ltd., Eyal Waldman, Michael Gray and Jacob Shulman, Case No. 13 CV 1225. The complaints were filed by Patrick Barnacle, David R. Ryan and Valentin Petrov, respectively, each for himself as a plaintiff and, purportedly, on behalf of persons purchasing the Company’s ordinary shares between April 19, 2012 and January 2, 2013 (the “Class Period”).

On May 14, 2013, the Court consolidated the Barnicle, Ryan and Petrov complaints and appointed lead plaintiffs and lead counsel. The consolidated case is captioned, In re Mellanox Technologies, Ltd. Securities Litigation, Case No. 13-cv-00925 (AKH). On July 12, 2013, an Amended Consolidated Complaint was filed against the same defendants. The Amended Consolidated Complaint alleges violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended, and Rule 10b-5 promulgated thereunder. The Amended Consolidated Complaint alleges that, during the Class Period, the defendants made false or misleading statements (or failed to disclose certain facts) regarding the Company’s business and outlook.

In the amended complaint, plaintiffs seek unspecified damages, an award of reasonable costs and expenses, including reasonable attorney’s fees, and any other relief deemed just and proper by the court.

Weinberger Case

On February 20, 2013, a request for approval of a class action was filed in the Economic Division of the District Court of Tel Aviv-Jaffa against Mellanox Technologies, Ltd., the Company’s President and CEO, former CFO, CFO and each of the members of the Company’s board of directors (the “Israeli Claim”). The Israeli Claim was filed by Mr. Avigdor Weinberger (the “Claimant”).  The Israeli Claim alleges that the Company, the board members, the Company’s President and CEO, its former CFO and its current CFO are responsible for making misleading statements (or failing to disclose certain facts) and filings to the public, as a result of which the shares of the Company were allegedly traded at a higher price than their true value during a period commencing on April 19, 2012 and ending January 2, 2013 and, therefore, these parties are responsible for damages caused to the purchasers of the Company’s shares on the Tel Aviv Stock Exchange during this time. The Claimant seeks an award of compensation to the relevant shareholders for all damages caused to them, including attorney fees and Claimant’s fee and any other relief deemed just and proper by the court. On April 24, 2013, the Claimant and the Company filed a procedural agreement with the court to stay the Israeli Claim pending the completion of the Barnicle, Ryan and Petrov cases disclosed herein. On April 24, 2013, the Israeli court approved this procedural agreement and stayed the Israeli proceedings. Based on currently available information, the Company believes that the resolution of this proceeding is not likely to have a material adverse effect on the Company’s business, financial position, results of operations or cash flows.

Infinite Data Case

On February 19, 2013, Infinite Data LLC, a Delaware limited liability company (“Infinite Data”) and a non-practicing entity and exclusive licensee of U.S. patent number 5,790,530 (the “Patent”), filed suit against approximately 25 of the Company’s end users and direct customers of its InfiniBand products in the United States District Court in Delaware. All approximately 25 actions include the same allegation of infringement regarding the Patent and seek the payment of damages, costs, expenses and injunctive relief. Several of the end users and direct customers sued by Infinite Data have tendered indemnification requests to the Company on the basis of existing contractual or asserted statutory obligations imposed on the Company to provide such indemnification. Based on currently available information, the Company believes that the resolution of these proceedings is not likely to have a material adverse effect on the Company’s business, financial position, results of operations or cash flows.

NOTE 11 — INCOME TAXES:

As of September 30, 2013 and December 31, 2012, the Company had unrecognized tax benefits of $22.0 million and $9.7 million, respectively. The Company established $9.2 million of unrecognized tax benefits in conjunction with the acquisitions of Kotura and IPtronics. It is the Company’s policy to classify accrued interest and penalties as part of the unrecognized tax benefits, or tax contingencies, and record the expense in the provision for income taxes. As of September 30, 2013 and December 31, 2012, the amount of accrued interest and penalties totaled $0.8 million and $0.4 million, respectively. As of September 30, 2013, calendar years 2008 through 2012 were open and subject to potential examination in one or more jurisdictions.

The Company’s effective tax rate is highly dependent upon the geographic distribution of its worldwide earnings or losses, tax regulations and tax holiday benefits in Israel, and the effectiveness of the Company’s tax planning strategies. The Company’s effective tax rates were (24.9)% and (35.5)% for the three and nine months ended September 30, 2013, respectively. The Company’s effective tax rates were 2.8% and 2.6% for the three and nine months ended September 30, 2012, respectively. The difference between the Company’s effective tax rates for the three and nine months ended September 30, 2013 and the 35% federal statutory rate resulted primarily from losses generated from non-US subsidiaries without tax benefit, along with non-tax-deductible expenses such as share-based compensation expense and the accrual of unrecognized tax benefits, and interest and penalties associated with unrecognized tax positions, partially offset by foreign earnings taxed at rates lower than the federal statutory rates.

The application of income tax law is inherently complex. Laws and regulations in this area are voluminous and are often ambiguous, and the Company is required to make many subjective assumptions and judgments regarding its income tax exposures. In addition, interpretations of and guidance surrounding income tax laws and regulations are subject to change over time. Any changes in the Company’s subjective assumptions and judgments could materially affect amounts recognized in its consolidated balance sheets and statements of income.

Overview

We are a fabless semiconductor company that produces and supplies high-performance interconnect products that facilitate efficient data transmission between servers, storage systems, communications infrastructure equipment and other embedded systems. We offer adapter, gateway and switch integrated circuits (“ICs”), adapter cards, switch systems, long-haul systems, gateway systems, software, services and cables, Variable Optical Attenuators, TransImpedance & Limiting Amplifiers and VCSEL Driver ICs as an integral part of a total end-to-end networking solution focused on computing, storage and communication applications used in multiple markets, including high-performance computing, or HPC, Web 2.0, storage, financial services, database and cloud. Our adapters and switch ICs provide per port bandwidth up to 10Gb/s, 40Gb/s and 56Gb/s Ethernet, and 10Gb/s (Single Data Rate or SDR), 20Gb/s (Double Data Rate or DDR), 40Gb/s (Quad Data Rate or QDR) and 56Gb/s (Fourteen Data Rate or FDR) InfiniBand. Our switch systems range in port density from 8, 18, 36, 48 and 64 port top-of-rack switches to director-class switches ranging in size from 108 to 648 ports. Connectivity between the adapters and switches is supported with our short reach copper cables and long reach active optical cables, and our management software provides visibility, monitoring and diagnostics for the system.

We are one of the pioneers of InfiniBand, an industry-standard architecture that provides specifications for high-performance interconnects. We believe InfiniBand interconnect solutions deliver industry-leading performance, efficiency and scalability of clustered computing and storage systems that incorporate our products. In addition to supporting InfiniBand, our products also support industry-standard Ethernet transmission protocols providing unique product differentiation and connectivity flexibility. Our products serve as building blocks for creating reliable and scalable InfiniBand and Ethernet solutions with leading performance.

On July 1, 2013, we completed the acquisition of IPtronics for a total purchase price of $42.8 million. We believe that the acquisition enhances our ability to deliver cost-effective, high-speed networks with next generation optical connectivity at 100Gb/s and beyond. The acquisition is expected to increase our competiveness and position as a leading provider of high-performance, end-to-end interconnect solutions for servers and storage systems.

On August 15, 2013, we completed the acquisition of Kotura, Inc. for a total purchase price of $80.7 million. The acquisition is expected to expand our ability to deliver cost-effective, high-speed networks with next generation optical connectivity. Kotura has an assembled workforce and a strong patent portfolio in the field of silicon photonics, a technology we expect to enhance our ability to offer interconnect solutions at per port bandwidths of 100 Gb/s and beyond.

Revenues. We derive revenues from sales of our ICs, cards, switch systems, cables, software and accessories. Our sales have historically been made on the basis of purchase orders rather than long-term agreements. Revenues were $285.3 million for the nine months ended September 30, 2013, compared to $378.7 million for the nine months ended September 30, 2012, representing a decrease of approximately 25%. The year-over-year revenue decrease was primarily due to increased revenues in the nine months ended September 30, 2012 related to pent up demand associated with the launch of Romley and Sandy Bridge platforms by Intel Corporation. In addition, our revenues in the nine months ended September 30, 2013 were negatively impacted by depletion of inventory accumulated at an OEM customer during the second half of 2012. Our revenues for the nine months ended September 30, 2013 are not necessarily indicative of future results.

Our products have broad adoption with multiple end customers across HPC, Web 2.0, cloud, EDC, financial services and storage markets; however, these markets are mainly served by leading server, storage and communications infrastructure OEMs.  Therefore, we have derived a substantial portion of our revenues from a relatively small number of OEM customers. Sales to our top ten customers represented 69% and 78% of our total revenues for the nine months ended September 30, 2013 and 2012, respectively. Sales to customers representing 10% or more of revenues accounted for 32% and 43% of our total revenues for the nine months ended September 30, 2013 and 2012, respectively. The loss of one or more of our principal customers, the reduction or deferral of purchases, or changes in the mix of our products ordered by any one of these customers could cause our revenues to decline materially if we are unable to increase our revenues from other customers. Our customers, including our most significant customers, are not obligated by long-term contracts to purchase our products and may cancel orders with limited potential penalties. If any of our large customers reduces or cancels its purchases from us for any reason, it could have an adverse effect on our revenues and results of operations.

23

At September 30, 2013 and December 31, 2012, based on information filed with the SEC or reported to us, Oracle Corporation held approximately 3.8 million of our ordinary shares. Sales to Oracle mainly through its contract manufacturers in the nine months ended September 30, 2013 and 2012 were $22.0 million and $19.5 million, respectively, and were conducted at arm’s-length. There were no other material transactions with Oracle during the nine months ended September 30, 2013 and 2012. At September 30, 2013 and December 31, 2012, accounts receivable from Oracle totaled $0.9 million and $0.2 million, respectively.

Cost of revenues and gross profit. The cost of revenues consists primarily of the cost of silicon wafers purchased from our foundry supplier, costs associated with the assembly, packaging and production testing of our ICs, outside processing costs associated with the manufacture of our adapter cards, and switch systems, purchased cable costs, royalties due to third parties, warranty costs, excess and obsolete inventory costs, depreciation and amortization, and costs of personnel associated with production management, quality assurance and services. In addition, after we purchase wafers from our foundries, we also face yield risk related to manufacturing these wafers into semiconductor devices. Manufacturing yield is the percentage of acceptable product resulting from the manufacturing process, as identified when the product is tested as a finished IC. If our manufacturing yields decrease, our cost per unit increases, which could have a significant adverse impact on our cost of revenues. We do not have long-term pricing agreements with foundry suppliers and contract manufacturers. Accordingly, our costs are subject to price fluctuations based on the overall cyclical demand for semiconductors.

We purchase our inventory pursuant to standard purchase orders. We estimate that lead times for delivery of our finished semiconductors from our foundry supplier and assembly, packaging and production testing subcontractor are approximately three to four months, lead times for delivery from our adapter card manufacturing subcontractor are approximately eight to ten weeks, and lead times for delivery from our switch systems manufacturing subcontractors are approximately twelve weeks. We build inventory based on forecasts of customer orders rather than the actual orders themselves.

We expect our cost of revenues as a percentage of sales to increase in the future as a result of a reduction in the average sale price of our products and a higher percentage of revenue deriving from sales of switch systems and cables, which generally yield lower gross margins. This trend will depend on overall customer demand for our products, our product mix, composition of our revenues by respective data rate, competitive product offerings and related pricing and our ability to reduce manufacturing costs.

Operational Expenses

Research and Development Expenses.  Our research and development expenses consist primarily of salaries, share-based compensation and associated costs for employees engaged in research and development, costs associated with computer aided design software tools, depreciation, allocable facilities and administrative expenses and tape-out costs. Tape-out costs are expenses related to the manufacture of new ICs, including charges for mask sets, prototype wafers, mask set revisions and testing incurred before releasing new ICs into production. We anticipate that our research and development expenses will increase as we continue to invest in development of new products and technologies.

Sales and Marketing Expenses. Sales and marketing expenses consist primarily of salaries, incentive compensation, share-based compensation and associated costs for employees engaged in sales, marketing and business development, commission payments to external sales representatives, advertising, and charges for trade shows, promotions, travel and allocable facilities and administrative expenses. We expect these expenses will increase in absolute dollars in future periods based on an increase in sales, marketing and business development personnel and increased marketing activities.

General and Administrative Expenses. General and administrative expenses consist primarily of salaries, share-based compensation and associated costs for employees engaged in finance, legal, human resources and administrative activities, and other professional service expenses for accounting, corporate legal fees and allocable facilities expenses. We expect these expenses will increase in absolute dollars in future periods based on an increase in personnel to support our business activities.

Amortization of Intangible Assets. Amortization of intangible assets relates to intangible assets resulting from our acquisitions of Voltaire Ltd., IPtronics A/S and Kotura, Inc. and purchases of patents and other license rights, which will be amortized over their estimated useful lives. Amortization is included in cost of revenues, research and development, sales and marketing or general and administrative expenses based upon the nature of the intangible asset.

Taxes on Income. Our operations in Israel have been granted “Approved Enterprise” status by the Investment Center of the Israeli Ministry of Industry, Trade and Labor and “Beneficiary Enterprise” status by the Israeli Income Tax Authority, which makes us eligible for tax benefits under the Israeli Law for Encouragement of Capital Investments, 1959. Under the terms of the Beneficiary

24

Enterprise program, income that is attributable to our operations in Yokneam, Israel will be exempt from income tax for a period of ten years commencing fiscal year 2011. Income that is attributable to our operations in Tel Aviv, Israel is subject to a reduced income tax rate (generally 10 to 25%, depending on the percentage of foreign investment in the Company) for five to eight years beginning fiscal year 2013. The Yokneam tax holiday is expected to expire in 2020 and the Tel Aviv tax holiday is expected to expire between 2015 and 2018.

In the first quarter of 2013, we realigned some of our business activities and, as a result, may utilize carryforward net operating losses in one of our subsidiaries in the future. The valuation allowance established for deferred tax assets will be released if it becomes more likely than not the subsidiary will generate sufficient future taxable income.

Critical Accounting Policies and Estimates

Our consolidated financial statements are prepared in accordance with generally accepted accounting principles in the United States. The preparation of these consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses and related disclosures. 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.

We believe that the assumptions and estimates associated with revenue recognition, allowance for doubtful accounts, fair value of financial instruments, short-term investments, warranty reserves, inventory reserves, share-based compensation expense, long-term asset valuations, investments, goodwill and purchased intangible asset valuation, deferred income tax asset valuation allowances, uncertain tax positions, litigation and other loss contingencies have the greatest potential impact on our consolidated financial statements. Therefore, we consider these to be our critical accounting policies and estimates. For further information on all of our significant accounting policies, please see Note 1 of the accompanying notes to our unaudited condensed consolidated financial statements.

See our Annual Report on Form 10-K for the year ended December 31, 2012, filed with the SEC on February 25, 2013, for a discussion of additional critical accounting policies and estimates. There have been no changes in our critical accounting policies as compared to what was disclosed in the Form 10-K for the year ended December 31, 2012.

Revenues. Revenues were $104.1 million for the three months ended September 30, 2013 compared to $156.5 million for the three months ended September 30, 2012, representing a decrease of 33.5%. The year-over-year revenue decrease was primarily due to increased revenues in the three months ended September 30, 2012 related to pent up demand associated with the launch of Romley and Sandy Bridge platforms by Intel Corporation. The revenues from sales by Kotura and IPtronics from their respective acquisition dates are included in the other revenues category. Revenues for the three months ended September 30, 2013 are not necessarily indicative of future results.

Gross Profit and Margin. Gross profit was $67.0 million for the three months ended September 30, 2013 compared to $108.1 million for the three months ended September 30, 2012, representing a decrease of 38.0%. As a percentage of revenues, gross margin decreased to 64.4% in the three months ended September 30, 2013 from 69.1% in the three months ended September 30, 2012. The gross margin percentage decrease was mainly due to product mix and increased warranty expenses associated with our expansion into new markets. Specifically, the portion of revenues attributed to ICs and boards declined in the three months ended September 30, 2013 while the portion of revenues attributable to switch and gateway systems increased. We garnish higher gross margins on sales of ICs and boards. In addition, gross profit in the third quarter of 2013 was impacted by an increase in amortization of acquired intangible assets in the amount of $1.9 million and acquisition related charges of $0.7 million associated with the acquisitions of Kotura and IPtronics. Gross margin for the three months ended September 30, 2013 is not necessarily indicative of future results.

Research and development expenses were $44.2 million in the three months ended September 30, 2013 compared to $36.2 million in the three months ended September 30, 2012, representing an increase of 22.0%. The increase in salaries and benefits and share-based compensation was attributable to headcount additions, including those associated with the Kotura and IPtronics acquisitions, partially offset by lower accrued bonuses. The increase in share-based compensation was attributable to RSUs granted to existing employees in the first quarter of fiscal 2013, RSUs grants to new hires and assumed RSUs and stock options from the Kotura and IPtronics acquisitions. Development and tape-out costs were higher in the third quarter of 2013 primarily due to higher mask, software costs, and product test expenses. The increase in other research and development costs was primarily attributable to higher depreciation, and amortization expenses due to amortization of acquired intangibles, other acquisition related charges as well as increased facilities and maintenance expenses. We expect that research and development expenses will increase in absolute dollars in future periods as we continue to devote more resources to develop new products, meet the changing requirements of our customers, expand into new markets and technologies and hire additional personnel.

Sales and Marketing.

The following table presents details of our sales and marketing expenses for the periods indicated:

	Three Months Ended September 30,
	2013		% of Revenues		2012		% of Revenues
	(In thousands)				(In thousands)
Salaries and benefits	$	10,287	9.9	%	$	8,447	5.4	%
Share-based compensation	2,407		2.3	%	2,476		1.6	%
Trade shows and promotions	2,449		2.4	%	2,908		1.8	%

Total sales and marketing	$	18,071	17.4	%	$	16,451	10.5	%

Sales and marketing expenses were $18.1 million for the three months ended September 30, 2013 compared to $16.5 million for the three months ended September 30, 2012, representing an increase of 9.8%. The increase in salaries and benefits was attributable to headcount additions, including those associated with the Kotura and IPtronics acquisitions, partially offset by lower accrued bonuses. The decrease in trade show and promotion costs was primarily due to a decrease in the volume of trade show and promotional activities, lower external sales commission and a decrease in expenses related to equipment for customer product evaluations. The increase in other sales and marketing costs was primarily attributable to higher amortization expenses due to acquired intangible assets in the amount of $0.8 million and acquisition related charges of $0.3 million.

General and Administrative.

The following table presents details of our general and administrative expenses for the periods indicated:

	Three Months Ended September 30,
	2013		% of Revenues		2012		% of Revenues
	(In thousands)				(In thousands)
Salaries and benefits	$	3,232	3.1	%	$	2,714	1.8	%
Share-based compensation	2,166		2.1	%	1,604		1.0	%
Professional services	3,715		3.5	%	1,113		0.7	%
Other general and administrative costs	487		0.5	%	781		0.5	%
Total general and administrative	$	9,600	9.2	%	$	6,212	4.0	%

General and administrative expenses were $9.6 million for the three months ended September 30, 2013 compared to $6.2 million for the three months ended September 30, 2012, representing an increase of 54.5%. The increase in salaries and benefits and share-

27

based compensation was attributable to headcount additions, including those associated with the Kotura and IPtronics acquisitions, partially offset by lower accrued bonuses. The increase in share-based compensation was attributable to RSUs granted to existing employees in the first quarter of fiscal 2013, RSU grants to new hires and assumed RSUs and stock options from the Kotura and IPtronics acquisitions. The increase in professional services costs was primarily due to $2.5 million of legal, accounting and consulting fees associated with the acquisitions of Kotura and IPtronics, as well as legal expenses related to the legal proceedings in which we are currently involved. The decrease in other general and administrative costs was due to lower human resources related costs.

For a further discussion of share-based compensation included in general and administrative expense, see “Share-based Compensation Expense” below.

Share-based Compensation Expense.

The following table summarizes the distribution of total share-based compensation expense in the consolidated statements of operations:

	Three Months Ended September 30,
	2013		2012
	(In thousands)
Cost of goods sold	$	461	$	406
Research and development	6,898		4,883
Sales and marketing	2,407		2,476
General and administrative	2,166		1,604
Total share-based compensation expense	$	11,932	$	9,369

Share-based compensation expense was $11.9 million for the three months ended September 30, 2013, compared to $9.4 million for the three months ended September 30, 2012, representing an increase of 27.4%. The increase in share-based compensation expense was primarily due to RSUs granted to existing employees in the first quarter of fiscal 2013, RSU grants to new hires and assumed RSUs and stock options from the Kotura and IPtronics acquisitions.

At September 30, 2013, there was $100.9 million of unrecognized share-based compensation cost related to non-vested share-based compensation arrangements. The costs are expected to be recognized over a weighted average period of 2.46 years.

At September 30, 2012, there was $86.9 million of unrecognized share-based compensation cost related to non-vested share-based compensation arrangements. The costs are expected to be recognized over a weighted average period of 2.81 years.

Other Income, Net. Other income, net consists of interest earned on cash and cash equivalents and short-term investments and foreign currency exchange gains and losses. Other income, net was $0.5 million for the three months ended September 30, 2013 compared to $0.6 million for the three months ended September 30, 2012. The slight decrease in other income, net is due to a decrease in interest income and lower foreign currency exchange gains.

Provision for Taxes on Income. Provision for taxes on income was $1.1 million for the three months ended September 30, 2013, compared to $1.4 million for the three months ended September 30, 2012. Effective January 2013, the Company’s income associated with the Tel Aviv, Israel area is subject to a reduced income tax rate. The effective tax rate was approximately (24.9)% and 2.8% for the three months ended September 30, 2013 and 2012, respectively. The difference between our effective tax rates and the 35% federal statutory rate resulted primarily from losses generated from non-US subsidiaries without tax benefit, along with non-tax-deductible expenses such as share-based compensation expense and the accrual of unrecognized tax benefits, and interest and penalties associated with unrecognized tax positions, partially offset by foreign earnings taxed at rates lower than the federal statutory rates.

Total revenue	$	285,315	100.0	%	$	378,681	100.0	%

Revenues. Revenues were $285.3 million for the nine months ended September 30, 2013 compared to $378.7 million for the nine months ended September 30, 2012, representing a decrease of 24.7%. The year-over-year revenue decrease was primarily due to increased revenues in the nine months ended September 30, 2012 related to pent up demand associated with the launch of Romley and Sandy Bridge platforms by Intel Corporation. In addition, our revenues in the nine months ended September 30, 2013 were negatively impacted by the depletion of inventory accumulated at an OEM customer during the second half of 2012. The revenues from sales by Kotura and IPtronics from their respective acquisition dates are included in the other revenues category. Revenues for the nine months ended September 30, 2013 are not necessarily indicative of future results.

Gross Profit and Margin. Gross profit was $187.2 million for the nine months ended September 30, 2013 compared to $259.7 million for the nine months ended September 30, 2012, representing a decrease of 27.9%. As a percentage of revenues, gross margin decreased to 65.6% in the nine months ended September 30, 2013 from 68.6% in the nine months ended September 30, 2012. The gross margin percentage decrease was mainly due to product mix and increased warranty expenses associated with our expansion into new markets. Specifically, the portion of revenues attributed to ICs and boards declined in the nine months ended September 30, 2013 while the portion of revenues attributable to switch and gateway systems increased. We garnish higher gross margins on sales of ICs and boards. In addition, gross profit in 2013 was impacted by higher amortization of acquired intangible assets from the Kotura and IPtronics acquisitions in the amount of $1.9 million and acquisition related charges of $0.7 million. Gross margin for the nine months ended September 30, 2013 is not necessarily indicative of future results.

Research and Development.

The following table presents details of our research and development expenses for the periods indicated:

	Nine Months Ended September 30,
	2013		% of Revenues		2012		% of Revenues
	(In thousands)				(In thousands)
Salaries and benefits	$	59,509	20.9	%	$	57,479	15.2	%

Other research and development costs	27,706		9.7	%	19,540		5.2	%
Total research and development	$	121,203	42.5	%	$	102,845	27.2	%

Research and development expenses were $121.2 million in the nine months ended September 30, 2013 compared to $102.8 million in the nine months ended September 30, 2012, representing an increase of 17.9%. The increase in salaries and benefits and share-based compensation was attributable to headcount additions, including those associated with the Kotura and IPtronics

29

acquisitions, partially offset by lower accrued bonuses. The increase in share-based compensation was attributable to RSUs granted to existing employees in the first quarter of fiscal 2013, RSUs grants to new hires and assumed RSUs and stock options from the Kotura and IPtronics acquisitions. Development and tape-out costs were higher primarily due to increased non-recurring engineering expenses and higher software costs, outsourcing and product development expenses. The increase in other research and development costs was primarily attributable to higher depreciation and amortization expenses due to amortization of acquired intangibles, as well as increased facilities and maintenance expenses. We expect that research and development expenses will increase in absolute dollars in future periods as we continue to devote more resources to develop new products, meet the changing requirements of our customers, expand into new markets and technologies and hire additional personnel.

Total sales and marketing	$	51,282	18.0	%	$	45,066	11.9	%

Sales and marketing expenses were $51.3 million for the nine months ended September 30, 2013 compared to $45.1 million for the nine months ended September 30, 2012, representing an increase of 13.8%. The increase in salaries and benefits and share-based compensation was attributable to headcount additions, including those associated with the Kotura and IPtronics acquisitions, partially offset by lower accrued bonuses. The decrease in trade show and promotion costs was primarily due to lower external sales commission. The increase in other sales and marketing costs was primarily attributable to higher amortization expenses due to acquired intangible assets related to the new acquisitions in the amount of $0.2 million and acquisition related charges of $0.3 million.

For a further discussion of share-based compensation included in sales and marketing expense, see “Share-based Compensation Expense” below.

General and Administrative.

The following table presents details of our general and administrative expenses for the periods indicated:

	Nine Months Ended September 30,
	2013		% of Revenues		2012		% of Revenues
	(In thousands)				(In thousands)
Salaries and benefits	$	8,278	2.9	%	$	7,941	2.1	%

Total general and administrative	$	27,132	9.5	%	$	17,405	4.6	%

General and administrative expenses were $27.1 million for the nine months ended September 30, 2013 compared to $17.4 million for the nine months ended September 30, 2012, representing an increase of 55.9%. The increase in salaries and benefits and share-based compensation was attributable to headcount additions, including those associated with the Kotura and IPtronics acquisitions, partially offset by lower accrued bonuses. The increase in share-based compensation was attributable to RSUs granted to existing employees in the first quarter of fiscal 2013, RSU grants to new hires and assumed RSUs and stock options from the Kotura and IPtronics acquisitions. The increase in professional services costs was primarily due to $6.8 million of legal, accounting and other

30

consulting fees associated with the acquisitions of Kotura and IPtronics, as well as legal expenses related to the legal proceedings in which the Company is currently involved. The increase in other general and administrative costs was due to higher facilities and maintenance expenses.

For a further discussion of share-based compensation included in general and administrative expense, see “Share-based Compensation Expense” below.

Share-based Compensation Expense.

The following table summarizes the distribution of total share-based compensation expense in the consolidated statements of operations:

	Nine months ended September 30,
	2013		2012
	(In thousands)
Cost of goods sold	$	1,359	$	1,176
Research and development	19,148		13,583
Sales and marketing	6,873		6,179
General and administrative	6,092		4,118
Total share-based compensation expense	$	33,472	$	25,056

Share-based compensation expense was $33.5 million for the nine months ended September 30, 2013, compared to $25.1 million for the nine months ended September 30, 2012, representing an increase of 33.6%. The increase in share-based compensation expense was primarily due to RSUs granted to existing employees in the first quarter of fiscal 2013, RSU grants to new hires and assumed RSUs and stock options from the Kotura and IPtronics acquisitions.

Other Income, Net. Other income, net consists of interest earned on cash and cash equivalents, short-term investments and foreign currency exchange gains and losses. Other income, net was $0.9 million for the nine months ended September 30, 2013, compared to $1.0 million for the nine months ended September 30, 2012. Interest income, net increased by $0.1 million and was partially offset by higher foreign currency exchange losses of $0.2 million.

Provision for Taxes on Income. Provision for taxes on income was $4.1 million for the nine months ended September 30, 2013, compared to $2.5 million for the nine months ended September 30, 2012. Effective January 2013, the Company’s income associated with the Tel Aviv, Israel area is subject to a reduced income tax rate. The effective tax rate was approximately (35.5)% and 2.6% for the nine months ended September 30, 2013 and 2012, respectively. The difference between our effective tax rates and the 35% federal statutory rate resulted primarily from losses generated from non-US subsidiaries without tax benefit, along with non-tax-deductible expenses such as share-based compensation expense and the accrual of unrecognized tax benefits, and interest and penalties associated with unrecognized tax positions, partially offset by foreign earnings taxed at rates lower than the federal statutory rates, partially offset by foreign earnings taxed at rates lower than the federal statutory rates.

Liquidity and Capital Resources

Historically, we have financed our operations through a combination of sales of equity securities and cash generated by operations. As of September 30, 2013, our principal source of liquidity consisted of cash and cash equivalents of $37.9 million and short-term investments of $257.7 million. During the third quarter of 2013, we completed acquisitions of IPtronics and Kotura and paid the total net cash purchase price of approximately $123.5 million from our existing capital resources. We expect that our current cash, cash equivalents, short-term investments, and cash flows from operating activities will be sufficient to fund our operations over the next twelve months after taking into account expected increases in research and development expenses, including tape out costs, higher sales and marketing and general and administrative expenses, and capital expenditures to support our infrastructure and growth.

Our cash position, short-term investments, restricted cash and working capital at September 30, 2013 and December 31, 2012 were as follows:

	September 30, 2013		December 31, 2012
	(in thousands)
Cash and cash equivalents	$	37,878	$	117,054
Short-term investments	257,672		302,593
Restricted cash, current	3,527		3,229
Restricted cash, long-term	7,360		3,388
Total	$	306,437	$	426,264
Working capital	$	337,667	$	431,745

Our ratio of current assets to current liabilities was 5.0:1 at September 30, 2013 and December 31, 2012.

31

Operating activities

Net cash provided by our operating activities amounted to $21.3 million and $157.1 million in the nine months ended September 30, 2013 and 2012, respectively. Net cash provided by operating activities in the nine months ended September 30, 2013 was primarily attributable to net non-cash items of $53.0 million partially offset by changes in assets and liabilities of $16.1 million and net loss of $15.6 million. Non-cash expenses consisted primarily of $30.7 million of share-based compensation, net of the excess tax benefits, and $25.4 million for depreciation and amortization, partially offset by deferred income taxes of $2.4 million. The $16.1 million cash outflow from changes in assets and liabilities resulted from an increase in accounts receivable of $12.1 million, a decrease of $8.7 million in accrued liabilities primarily due to the payment of accrued bonuses for fiscal year 2012, and a decrease in accounts payable of $8.9 million primarily due to payments to contract manufacturers for inventory purchased in fiscal 2012, partially offset by a decrease in inventories of $12.9 million as we continued to fulfill customer orders from existing inventories and a decrease in prepaid expenses and other assets of $0.7 million.

Net cash provided by operating activities was $157.1 million in the nine months ended September 30, 2012. Net cash provided by operating activities in the nine months ended September 30, 2012 was primarily attributable to net income of $92.9 million, adjusted by net non-cash items of $34.4 million and changes in assets and liabilities of $29.8 million. Non-cash expenses consisted primarily of $22.1 million of share-based compensation, net of the excess tax benefits, and $17.1 million for depreciation and amortization, and were partially offset by deferred income taxes of $4.4 million. The $29.8 million cash inflow from changes in assets and liabilities resulted from an increase of $37.4 million in accrued liabilities primarily due to higher payroll obligations and an increase in accounts payable of $9.9 million due to the higher volume of purchases during the period, and was partially offset by an increase in inventories of $9.9 million to support higher demand from our customers, an increase in accounts receivable of $4.3 million and an increase in prepaid expenses and other assets of $3.3 million.

Investing activities

Net cash used in investing activities was $115.9 million in the nine months ended September 30, 2013. Cash used in investing activities was primarily attributable to the acquisitions of Kotura and IPtronics in the amount of $123.5 million, purchases of property and equipment of $24.1 million, purchases of intangible assets of $6.4 million, an increase in restricted cash deposits by $3.9 million and an equity investment of $3.1 million in private companies partially offset by net sales and maturities of short-term investments of $45.8 million.

Net cash used in investing activities was $230.0 million in the nine months ended September 30, 2012. Cash used in investing activities was primarily attributable to net purchases of short-term investments of $207.2 million, purchases of property and equipment of $20.9 million and an equity investment of $1.4 million in a private company.

Financing activities

Our financing activities generated $15.4 million in the nine months ended September 30, 2013. Cash provided by financing activities was primarily due to proceeds of $13.6 million from share option exercises and purchases pursuant to our employee share purchase plan and an excess tax benefit from share-based compensation of $2.8 million, partially offset by principal payments on capital lease obligations of $1.0 million.

Our financing activities generated $29.5 million in the nine months ended September 30, 2012. Cash provided by financing activities was primarily due to proceeds of $27.3 million from stock option exercises and purchases pursuant to our employee stock purchase plan, and an excess tax benefit from share-based compensation of $2.9 million, and was partially offset by principal payments on capital lease obligations of $0.6 million.

32

Off-Balance Sheet Arrangements

As of September 30, 2013, we did not have any off-balance sheet arrangements.

Contractual Obligations

The following table summarizes our contractual obligations at September 30, 2013, and the effect those obligations are expected to have on our liquidity and cash flows in future periods:

			Payments Due by Period
Contractual Obligations:	Total		Less Than 1 Year		1-3 Years		3-5 Years		Beyond 5 Years
	(in thousands)
Commitments under capital lease	$	3,128	$	344	$	2,784	$	—	$	—
Non-cancelable operating lease commitments	54,124		16,451		19,027		10,740		7,906

Total	$	110,111	$	67,810	$	23,505	$	10,890	$	7,906

For purposes of this table, purchase obligations for the purchase of goods or services are defined as agreements that are enforceable and legally binding and that specify all significant terms including: fixed or minimum purchase quantities; fixed, minimum or variable price provisions; and the approximate timing of the transaction. Our purchase orders are based on our current manufacturing needs and are fulfilled by our vendors within short time horizons. We do not have significant agreements for the purchase of raw materials or other goods specifying minimum quantities or set prices that exceed our expected requirements.

Recent Accounting Standards

See Note 1, “The Company and Summary of Significant Accounting Policies—Recent accounting pronouncements” of the Notes to the Unaudited Condensed Consolidated Financial Statements, included in Part I, Item 1 of this report, for a full description of recent accounting standards, including the respective dates of adoption and effects on our condensed consolidated financial position, results of operations and cash flows.

ITEM 3 — QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rate Fluctuation Risk

We do not have any long-term borrowings. Our investments consist of cash and cash equivalents, short-term deposits, and interest bearing investments in U.S. government debt securities and corporate bonds with an average maturity of less than one year. The primary objective of our investment activities is to preserve principal while maximizing income without significantly increasing risk. By policy, we limit the amount of our credit exposure through diversification and restricting our investments to highly rated securities. At the time of purchase, we do not invest more than 3% of the total investment portfolio in individual securities, except U.S. Treasury or agency securities. Highly rated securities are defined as having a minimum Moody or Standard & Poor’s rating of A2 or A, respectively. We have not experienced any material losses on cash equivalents or short-term investments. We do not enter into investments for trading or speculative purposes. Our investments are exposed to market risk due to a fluctuation in interest rates, which may affect our interest income and the fair market value of our investments. Due to the short-term nature of our investment portfolio, we do not believe an immediate 1% change in interest rates would have a material effect on the fair market value of our portfolio, and therefore we do not expect our operating results or cash flows to be materially affected by a sudden change in market interest rates.

Foreign Currency Exchange Risk

We derive all of our revenues in U.S. dollars. The U.S. dollar is our functional and reporting currency in all of our foreign locations. However, a significant portion of our headcount related expenses, consisting principally of salaries and related personnel expenses, and our Israeli facility expenses are denominated in new Israeli shekels, or NIS. This foreign currency exposure gives rise to market risk associated with exchange rate movements of the U.S. dollar against the NIS. Furthermore, we anticipate that a material portion of our expenses will continue to be denominated in NIS. To the extent the U.S. dollar weakens against the NIS, we will experience a negative impact on our profits.

33

To protect against reductions in the value and the volatility of future cash flows caused by changes in foreign currency exchange rates, we have established a balance sheet and anticipated transaction risk management program. Currency forward contracts and natural hedges are generally utilized in this hedging program. We do not enter into forward contracts for trading or speculative purposes. Our hedging program reduces, but does not eliminate, the impact of currency exchange rate movements (see Part II, Item 1A, “Risk Factors”). If we were to experience a 10% change in currency exchange rates, the impact on assets and liabilities denominated in currencies other than the U.S. dollar, after taking into account hedges and offsetting positions, would result in a gain before taxes of approximately $0.1 million at September 30, 2013. There would also be an impact on future operating expenses denominated in currencies other than the U.S. dollar. At September 30, 2013, approximately $11.4 million of our monthly operating expenses were denominated in NIS. As of September 30, 2013, we had forward contracts in place that hedged future operating expenses of approximately 134.0 million NIS, or approximately $37.9 million based upon the exchange rate on September 30, 2013. The forward contracts cover a portion of future NIS denominated operating expenses expected to occur over the next twelve months. Our derivatives expose us to credit risk to the extent that the counterparties may be unable to meet the terms of the agreement. We seek to mitigate such risk by limiting our counterparties to major financial institutions and by spreading the risk across a number of major financial institutions. However, failure of one or more of these financial institutions could result in incurred losses.

ITEM 4 — CONTROLS AND PROCEDURES

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and that such information is accumulated and communicated to our management, including our chief executive officer and chief financial officer, as appropriate, to allow for timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

As required by Rule 13a-15(b) under the Exchange Act, we carried out an evaluation, under the supervision and with the participation of our management, including our chief executive officer and chief financial officer, of the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this Quarterly Report on Form 10-Q. Based on the foregoing, our chief executive officer and chief financial officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

Changes in Internal Control Over Financial Reporting

During the quarter, we completed the acquisitions of IPtronics A/S and Kotura, Inc. Other than the impact of these business combinations, there has been no change in our internal control over financial reporting during our most recent quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

ITEM 1 — LEGAL PROCEEDINGS

See Note 8, “Commitments and Contingencies—Legal proceedings” of the Notes to the Unaudited Condensed Consolidated Financial Statements, included in Part I, Item 1 of this report, for a full description of legal proceedings and related contingencies and their effects on our condensed consolidated financial position, results of operations and cash flows.

We may, from time to time, become a party to various other legal proceedings arising in the ordinary course of business. We may also be indirectly affected by administrative or court proceedings or actions in which we are not involved, but which have general applicability to the semiconductor industry.

ITEM 1A — RISK FACTORS

Investing in our ordinary shares involves a high degree of risk. You should carefully consider the following risk factors, in addition to the risk factors previously disclosed in our Annual Report on Form 10-K for the year ended December 31, 2012, the other information set forth in this report and our other filings with the SEC, before purchasing our ordinary shares. Each of these risk factors could harm our business, financial condition or operating results, as well as decrease the value of an investment in our ordinary shares.

There have been no material changes from risk factors previously disclosed in our Annual Report on Form 10-K for the year ended December 31, 2012, except for the following:

Risks Related to Our Business

We may pursue acquisitions of other companies or new or complementary products, technologies and businesses, which could harm our operating results, may disrupt our business and could result in unanticipated accounting charges.

In the third quarter of 2013, we acquired IPtronics and Kotura. We may pursue acquisitions of other companies or new or complementary products, technologies and businesses in the future. Acquisitions create additional, material risk factors for our business that could cause our results to differ materially and adversely from our expected or projected results. Such risk factors include the effects of possible disruption to the continued expansion of our product lines, potential changes in our customer base and changes to the total available market for our products, reduced demand for our products, the impact of any such acquisition on our financial results, negative customer reaction to any such acquisition, reduced investment income as a result of lower cash and investment balances and our ability to successfully integrate an acquired company’s operations with our operations.

Acquisitions, such as our acquisitions of IPtronics and Kotura, present a number of other potential risks and challenges that could disrupt our business operations. For example, we may not be able to successfully negotiate or finance the acquisition on favorable terms. If an acquired company also has inventory that we assume, we will be required to write up the carrying value of that inventory to its fair value. When that inventory is sold, the gross margins for those products are reduced and our gross margins for that period are negatively affected. Furthermore, the purchase price of any acquired businesses may exceed the current fair values of the net tangible assets of such acquired businesses. As a result, we would be required to record material amounts of goodwill, acquired in-process research and development and other intangible assets, which could result in significant impairment and acquired in-process research and development charges and amortization expense in future periods. These charges, in addition to the results of operations of such acquired businesses and potential restructuring costs associated with an acquisition, could have a material adverse effect on our business, financial condition and results of operations. We cannot forecast the number, timing or size of future acquisitions, or the effect that any such acquisitions might have on our operating or financial results. Furthermore, potential acquisitions, whether or not consummated, will divert our management’s attention and may require considerable cash outlays at the expense of our existing operations. In addition, to complete future acquisitions, we may issue equity securities, incur debt, assume contingent liabilities or have amortization expenses and write-downs of acquired assets, which could adversely affect our profitability.

We depend on a small number of customers for a significant portion of our sales, and the loss of any one of these customers will adversely affect our revenues.

A small number of customers account for a significant portion of our revenues. For the three months ended September 30, 2013, sales to IBM and Hewlett-Packard accounted for 17% and 12%, respectively, of our total revenues, while sales to our top ten customers accounted for 68% of our revenues. For the three months ended September 30, 2012, sales to Hewlett-Packard, IBM and Polywell Computers accounted for 19%, 18% and 11%, respectively, of our total revenues, while sales to our top ten customers accounted for 80%. of our revenues. For the year ended December 31, 2012, sales to Hewlett-Packard and IBM accounted for 20% and 19%, respectively, of our total revenues, while sales to our top ten customers accounted for 74% of our revenues. Because the majority of servers, storage, communications infrastructure equipment and embedded systems are sold by a relatively small number of vendors, we expect that we will continue to depend on a small number of customers to account for a significant percentage of our revenues for the foreseeable future. Our customers, including our most significant customers, are not obligated by long-term contracts to purchase our products and may cancel orders with limited potential penalties. If any of our large customers reduces or cancels its purchases from us for any reason, it could have an adverse effect on our revenues and results of operations.

35

Risks Related to Operations in Israel and Other Foreign Countries

We are susceptible to additional risks from our international operations.

We derived 48% and 53% of our revenues in the three months ended September 30, 2013 and 2012, respectively, from sales outside of North America. As a result, we face additional risks from doing business internationally, including:

·reduced protection of intellectual property rights in some countries;

·difficulties in staffing and managing foreign operations;

·longer sales and payment cycles;

·greater difficulties in collecting accounts receivable;

·adverse economic conditions;

·seasonal reductions in business activity;

·potentially adverse tax consequences;

·laws and business practices favoring local competition;

·costs and difficulties of customizing products for foreign countries;

·compliance with a wide variety of complex foreign laws and treaties;

·compliance with the United States’ Foreign Corrupt Practices Act and similar anti-bribery laws in other jurisdictions;

·compliance with export control and regulations;

·licenses, tariffs, other trade barriers, transit restrictions and other regulatory or contractual limitations on our ability to sell or develop our products in certain foreign markets;

·foreign currency exchange risks;

·fluctuations in freight rates and transportation disruptions;

·political and economic instability;

·variance and unexpected changes in local laws and regulations;

·natural disasters and public health emergencies; and

·trade and travel restrictions.

Our principal research and development facilities are located in Israel, and our directors, executive officers and other key employees are located primarily in Israel and the United States. In addition, we engage sales representatives in various countries throughout the world to market and sell our products in those countries and surrounding regions. If we encounter any of the above risks in our international operations, we could experience slower than expected revenue growth and our business could be harmed.

Exchange rate fluctuations between the U.S. dollar and the NIS may negatively affect our earnings.

Although all of our revenues and a majority of our expenses are denominated in U.S. dollars, a significant portion of our research and development expenses and our Israeli facility expenses are incurred in new Israeli shekels, or NIS. As a result, we are exposed to risk to the extent that the inflation rate in Israel exceeds the rate of devaluation of the NIS in relation to the U.S. dollar, or if the timing of these devaluations lags behind inflation in Israel. In that event, the U.S. dollar cost of our research and development operations in

36

Israel will increase and our U.S. dollar-measured results of operations will be adversely affected. To the extent that the value of the NIS increases against the U.S. dollar, our expenses on a U.S. dollar cost basis increase. We cannot predict any future trends in the rate of inflation in Israel or the rate of appreciation of the NIS against the U.S. dollar. If the U.S. dollar cost of our research and development operations and facility expenses in Israel increases, our dollar-measured results of operations will be adversely affected. Our operations also could be adversely affected if we are unable to guard against currency fluctuations in the future. Further, because all of our international revenues are denominated in U.S. dollars, a strengthening of the dollar versus other currencies could make our products less competitive in foreign markets and the collection of our receivables more difficult. To help manage this risk we have been engaged in foreign currency hedging activities. These measures, however, may not adequately protect us from material adverse effects due to the impact of inflation in Israel and changes in value of NIS against the U.S. dollar.

Risks Related to Our Ordinary Shares

The ownership of our ordinary shares will continue to be highly concentrated, and your interests may conflict with the interests of our existing shareholders.

As of September 30, 2013, based on information filed with the SEC or reported to us, Oracle Corporation and certain entities affiliated with Fidelity Management & Research Company, Migdal Insurance and Financial Holdings, Psagot Investments House Ltd. and T. Rowe Price Associates, Inc. beneficially owned an aggregate of approximately 41% of our outstanding ordinary shares, and taken together with our executive officers and directors and their affiliates, beneficially owned an aggregate of approximately 47% of our outstanding ordinary shares. Accordingly, these shareholders, should they act as a group, would have significant influence over the outcome of corporate actions requiring shareholder approval, including the election of directors, any merger, consolidation or sale of all or substantially all of our assets or any other significant corporate transaction. These shareholders could delay or prevent a change of control of our company, even if such a change of control would benefit our other shareholders. The significant concentration of share ownership may adversely affect the trading price of our ordinary shares due to investors’ perception that conflicts of interest may exist or arise.

The price of our ordinary shares may continue to be volatile, and the value of an investment in our ordinary shares may decline.

During the three months ended September 30, 2013, our shares traded as low as $33.69 and as high as $54.89 per share. During the last 52 weeks our shares traded as low as $33.69 per share and as high as $111.38 per share. Factors that could cause volatility in the market price of our ordinary shares include, but are not limited to:

·quarterly variations in our results of operations or those of our competitors;

·announcements by us, our competitors, our customers or rumors from sources other than our company related to acquisitions, new products, significant contracts, commercial relationships, capital commitments or changes in the competitive landscape;

·our ability to develop and market new and enhanced products on a timely basis;

·disruption to our operations;

·geopolitical instability;

·the emergence of new sales channels in which we are unable to compete effectively;

·any major change in our board of directors or management;

·changes in financial estimates, including our ability to meet our future revenue and operating profit or loss projections;

·changes in governmental regulations or in the status of our regulatory approvals;

·general economic conditions and slow or negative growth of related markets;

·commencement of, or our involvement in, litigation;

·changes in earnings estimates or recommendations by securities analysts;

37

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

·continuing international conflicts and acts of terrorism; and

·changes in accounting rules.

We have initiated the process to delist our ordinary shares from the Tel Aviv Stock Exchange (the “TASE”). Although our ordinary shares will continue to be listed on NASDAQ, delisting from the TASE could reduce the trading volume and liquidity of our ordinary shares, which could increase the volatility in the market price of our ordinary shares. In addition, the stock markets in general, and the markets for semiconductor stocks in particular, have experienced extreme volatility that often has been unrelated to the operating performance of the issuer. These broad market fluctuations may adversely affect the trading price or liquidity of our ordinary shares. When the market price of a stock has been volatile and declined, holders of that stock have sometimes instituted securities class action litigation against the issuer. Lawsuits brought against us by shareholders, such as the shareholder class action suits filed in February 2013 against us and certain of our current and former executive officers, could cause us to incur substantial costs defending the lawsuits and divert the attention of our management from the operation of our business.
