Notes to Condensed Consolidated Financial Statements

(Unaudited)

1. Description of the Company

The Company

Gigamon Inc. (the “Company”) designs, develops and sells products and services that together provide customers visibility and control of network traffic. The Company serves global enterprises, governments and service providers that seek to maintain and improve the security, reliability and performance of their network infrastructure.

2. Summary of Significant Accounting Policies

Basis of Presentation and Consolidation

The Company prepared its condensed consolidated financial statements in accordance with U.S. generally accepted accounting principles (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (the “SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. As such, the unaudited information included in this Quarterly Report on Form 10-Q should be read in conjunction with the audited consolidated financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2016.

There have been no changes to the Company’s significant accounting policies described in the Annual Report on Form 10-K that have had a material impact on the Company’s condensed consolidated financial statements and related notes except for the adoption of the accounting standard update related to Improvements to Employee Share-Based Payment Accounting, which amends Compensation - Stock Compensation and the accounting standard update related to restricted cash, which affected the presentation in the condensed consolidated statements of cash flows.

Certain prior periods’ amounts were reclassified to conform to the current year’s presentation. None of these reclassifications impacted the reported net income (loss) or earnings per share for any of the periods presented.

The Company's fiscal year is 52 or 53 weeks and ends on the last Saturday in December. Fiscal 2016 was a 53-week fiscal year ending on December 31, 2016; the first quarter was a 14-week quarter ended on April 2, 2016 and each subsequent quarter was a 13-week quarter. Fiscal 2017 is a 52-week fiscal year ending on December 30, 2017, with each quarter therein being a 13-week quarter.

Unaudited Interim Financial Statements

The accompanying unaudited interim condensed consolidated financial statements have been prepared on a basis consistent with the annual consolidated financial statements and, in the opinion of management, reflect all adjustments, which include normal recurring adjustments, necessary to fairly state the Company’s financial position as of September 30, 2017, its results of operations and comprehensive income (loss) for the three and nine months ended September 30, 2017 and October 1, 2016, respectively, and cash flows for the nine months ended September 30, 2017 and October 1, 2016, respectively. The financial data and the other financial information disclosed in the accompanying notes to the condensed consolidated financial statements related to these three and nine month periods are also unaudited. The fiscal year-end condensed consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by GAAP. The condensed consolidated statements of operations for the three and nine months ended September 30, 2017 is not necessarily indicative of the results to be expected for the full fiscal year or any other future periods.

Principles of Consolidation

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

Use of Estimates

The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make certain 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 revenues and expenses during the reported periods. On an ongoing basis, the Company evaluates its estimates, including but not limited to those related to revenue recognition, allowance for doubtful accounts, warranty reserve, excess and obsolete inventory write-downs, stock-based compensation expense, depreciable useful lives and income taxes. The Company

bases its estimates on historical experience, projections for future performance and other assumptions that it believes to be reasonable under the circumstances. Actual results could differ materially from those estimates.

Concentrations

The Company operates in highly competitive and rapidly changing markets that could negatively impact the Company’s operating results. A number of components that meet the Company’s manufacturing requirements are available only from single source suppliers. In addition, the Company relies on two contract manufacturers to manufacture a substantial majority of its products. The inability of its single source suppliers and contract manufacturers to provide the Company with adequate supplies of high-quality components and products could cause a delay in order fulfillment, which could adversely affect the Company’s revenue, cost of revenue and operating results.

Financial instruments that potentially subject the Company to significant concentrations of credit risk consist principally of cash, cash equivalents, short-term investments and accounts receivable. The majority of the Company's cash, cash equivalents and short-term investments are held in, or managed by a limited number of major financial institutions in the United States that management believes are creditworthy. Such deposits may exceed the insured limits provided on them. The Company mitigates credit risk associated with its accounts receivable by performing ongoing credit evaluations of its customers and determines if it needs to establish an allowance for doubtful accounts for estimated losses based on management’s assessment of the collectability of customer accounts.

The following customers represented more than 10% or more of total revenue or accounts receivable:



	Three Months Ended				Nine Months Ended

Recent Accounting Pronouncements

New Accounting Updates Recently Adopted

The Company has adopted the accounting standard update related to Improvements to Employee Share-Based Payment Accounting, which amends Compensation – Stock Compensation during the first quarter of fiscal 2017. Specifically, the Company elected to account for forfeitures as they occur, rather than estimate expected forfeitures. The net cumulative effect of the change was recognized as a $3.6 million reduction to retained earnings as of January 1, 2017. Stock-based excess tax benefits or shortfalls are now reflected in the results of operations as a component of the income tax benefit (provision), whereas they previously were recognized in equity. The cumulative impact of this change was recorded as a deferred tax asset of $7.6 million for the previously unrecognized excess tax benefits with an adjustment of $7.1 million and $0.5 million to retained earnings and a valuation allowance for a certain jurisdiction, respectively. Additionally, the Company's condensed consolidated statements of cash flows now include excess tax benefits as an operating activity with the prior period adjusted accordingly.

The Company has adopted the restricted cash guidance, which requires amounts generally described as restricted cash and restricted cash equivalents be included with cash and cash equivalents when reconciling the total beginning

and ending amounts for the periods presented in the condensed consolidated statements of cash flows in the first quarter of fiscal 2017 using a retrospective transition method for each period presented.

Recent Accounting Updates Not Yet Effective

In May 2014, the Financial Accounting Standards Board (the "FASB") issued an accounting standard update related to revenue from contracts with customers, which supersedes the revenue recognition requirements in the current Accounting Standards Codification. This standard is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This standard also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. In August 2015, the FASB voted to defer the effective date of this standard by one year. Additionally, in March 2016 the FASB issued additional information that clarifies the implementation guidance on principal versus agent considerations. The new standard permits adoption either by using (i) a full retrospective approach for all periods presented in the period of adoption or (ii) a modified retrospective approach with the cumulative effect of initially applying the new standard recognized at the date of initial application and providing certain additional disclosures. The new standard is effective for annual reporting periods beginning after December 15, 2017, with early adoption permitted for annual reporting periods beginning after December 15, 2016. The Company did not elect to early adopt, and accordingly, it will adopt the new standard effective for its fiscal year 2018.

The Company is evaluating the impact of the new standard on its accounting policies, processes, and system requirements and currently plans to adopt using the full retrospective approach. However, a final decision regarding the adoption method has not been finalized at this time. The Company's final determination will depend on a number of factors, such as the significance of the impact of the new standard on our financial results, system readiness, including that of software procured from third-party providers, and its ability to accumulate and analyze the information necessary to assess the impact on prior period financial statements, as necessary.

Revenue recognition for non-essential software is currently accounted for under the Software Revenue Recognition guidance, which entails allocating the arrangement consideration to deliverables that have established vendor specific objective evidence value (“VSOE”) or fair value and the residual to other deliverables based on third party evidence or best estimates of selling prices. Revenue from each deliverable is then recognized when all requirements are met for that specific deliverable. As the new standard does not retain the concept of VSOE, the Company preliminarily believes it will use the Standalone Selling Price to determine the appropriate amount to be allocated to each separate performance obligation using the Relative Selling Price approach. As part of the Company's preliminary evaluation, it has also considered the impact of the guidance relating to Other Assets and Deferred Costs; Contracts with customers, and the interpretations of the FASB Transition Resource Group for Revenue Recognition ("TRG") from their November 7, 2016 meeting with respect to capitalization and amortization of incremental costs of obtaining a contract. As a result of this new guidance, the Company preliminarily believes that it will capitalize certain costs of obtaining a contract, including additional sales commissions, as the new cost guidance, as interpreted by the TRG, requires the capitalization of all incremental costs that the Company incurs to obtain a contract with a customer that it would not have incurred if the contract had not been obtained, provided it expects to recover the costs. Under the Company's current accounting policy, it expenses the commission costs immediately as incurred.

While the Company continues to assess the potential impacts of the new standard, it anticipates this standard could have a material impact on its consolidated financial statements. However, the Company cannot reasonably estimate quantitative information related to the impact of the new standard on its consolidated financial statements at this time.

In February 2016, the FASB issued an accounting standard update which amends the existing accounting standards for leases. Consistent with current guidance, the recognition, measurement and presentation of expenses and cash flows arising from a lease by a lessee primarily will depend on its classification. Under the new guidance, a lessee will be required to recognize assets and liabilities for all leases with lease terms of more than 12 months. The effective date of this update will be for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018 using a modified retrospective transition method with early adoption permitted. The Company expects the standard to have a material impact on its assets and liabilities for the addition of right-of-use assets and lease liabilities, but the Company does not expect it to have a material impact on its results of operations or liquidity.

In June 2016, the FASB issued new guidance that changes the accounting for recognizing impairments of financial assets. Under the new guidance, credit losses for certain types of financial instruments will be estimated based on expected losses. The new guidance also modifies the impairment models for available-for-sale debt securities and for purchased financial assets with credit deterioration since their origination. The effective date of this standard will be

for annual periods ending after December 15, 2019, and interim periods within that reporting period. Early adoption is permitted starting in annual periods ending after December 15, 2018. The Company is evaluating the impact of this guidance on its consolidated financial statements.

In October 2016, the FASB issued new guidance that requires a reporting entity to recognize the tax expense from intra-entity asset transfers of assets other than inventory in the selling entity’s tax jurisdiction when the transfer occurs, even though the pre-tax effects of that transaction are eliminated in consolidation. Any deferred tax asset that arises in the buying entity’s jurisdiction would also be recognized at the time of the transfer. The new guidance will likely impact reporting entities’ effective tax rates. The new guidance is effective for interim and annual periods beginning after December 15, 2017 and early adoption is permitted. The amendment should be adopted using the modified retrospective approach with a cumulative-effect adjustment recorded in retained earnings as of the beginning of the period of adoption. The Company is evaluating the impact of this guidance on its consolidated financial statements.

3. Fair Value Measurements

The inputs used in the valuation methodologies in measuring fair value are defined in the fair value hierarchy as follows:

Level 1 – Quoted prices in active markets for identical assets or liabilities.

Level 2 – Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

The categorization of a financial instrument within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The carrying value of the Company’s accounts receivable, accounts payable and accrued liabilities approximates their fair value due to the short-term nature of these instruments.

Cash Equivalents and Short-Term Investments

The components of the Company’s cash equivalents and short-term investments are as follows (in thousands):

U.S. government securities	64,475		—		64,475
Total short-term investments	$	109,238	$	—	$	109,238

The Company considers all highly liquid investments with maturity of three months or less at the time of purchase to be cash equivalents. The Company holds money market funds that invest primarily in high-quality short-term money-market instruments, and these funds are not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The Company presents available-for-sale investments as current assets as they are available for the Company's current operations.

Money market funds have been classified as Level 1 because these securities are valued based upon quoted prices in active markets. The Company’s Level 2 assets are priced using quoted market prices for similar instruments or non-binding market prices that are corroborated by observable market data. The Company uses inputs such as actual trade data, benchmark yields, broker/dealer quotes or alternative pricing sources with reasonable levels of price transparency which are obtained from quoted market prices, independent pricing vendors or other sources, to determine the ultimate fair value of these assets. The Company has no assets classified as Level 3. The Company’s policy is to recognize transfers among Level 1, Level 2 and Level 3 classifications as of the actual date of the events or change in circumstances that caused the transfers. The Company did not have any transfers between Level 1 and Level 2 in the nine months ended September 30, 2017.

As of September 30, 2017 and December 31, 2016, the Company had no liabilities measured at fair value.

5. Commitments and Contingencies

Lease Commitments

The Company leases office space for its current headquarters in Santa Clara, California and its United Kingdom subsidiary under non-cancelable operating leases that expire at various dates through fiscal 2025. The Company has also entered into lease agreements for additional office space in India, Sweden and Singapore. The Company recognizes rent expense on a straight-line basis over the lease period.

Rent expense related to the Company’s operating leases was $1.5 million and $1.0 million for the three months ended September 30, 2017 and October 1, 2016, respectively, and $3.8 million and $2.9 million for the nine months ended September 30, 2017 and October 1, 2016, respectively.

No material change in the future minimum lease payments under non-cancelable operating leases has occurred in the nine months ended September 30, 2017 and as reported in the Annual Report on Form 10-K for the fiscal year ended December 31, 2016.

Purchase Commitments

The Company has agreements with two contract manufacturers for the manufacture of its products. The agreement with its primary contract manufacturer allows the contract manufacturer to procure components on the Company’s behalf based upon a production forecast provided by the Company. The Company also purchases raw materials directly from suppliers to be used by the contract manufacturers in the production of the Company’s products. The Company may be obligated to purchase component inventory that is non-cancelable. As of September 30, 2017 and December 31, 2016, the Company’s non-cancelable purchase commitments for such component inventory were $22.2 million and $15.7 million, respectively.

Legal Proceedings

On January 27, 2017, a purported shareholder class action was filed in the United States District Court for the Northern District of California against the Company and three of its current and former officers. The plaintiff alleges that the Company made false and misleading statements about the Company’s business, operations, and prospects, including statements about the Company’s guidance, for the fourth quarter of 2016. The complaint, which was amended on September 22, 2017, seeks unspecified monetary damages, attorneys' fees and costs and other relief. The Company believes this lawsuit is without merit and intends to defend against it vigorously. The matter is still in the early stages and the Company will defend against the allegations accordingly. Due to the current early stage of the proceedings, the Company cannot reasonably estimate the loss or the range of possible losses, if any.

Indemnification Obligations

Under the indemnification provisions of its standard sales related contracts, the Company agrees to defend its customers against third-party claims asserting infringement of certain intellectual property rights, which may include patents, copyrights, trademarks, or trade secrets, and to pay judgments entered on such claims. The Company’s exposure under these indemnification provisions is generally limited to the total amount paid by its customer under the agreement. However, certain agreements include indemnification provisions that could potentially expose the Company to losses in excess of the amount received under the agreement. The Company has not incurred any costs as a result of such indemnifications and has not accrued any liabilities related to such obligations in its condensed consolidated financial statements. In addition, the Company indemnifies its officers, directors and certain key employees while they are serving in good faith in the company capacities. To date, there have been no claims under any indemnification provisions.

6. Stockholders’ Equity

Equity Award Plans

2013 Equity Incentive Plan

In May 2013, the Company adopted the 2013 Equity Incentive Plan (the “2013 Equity Plan”). All authorized but unissued shares of the Company’s 2012 Unit Option Plan (the “2012 Plan”) were added to the 2013 Equity Plan’s authorized pool in June 2013. The Company is authorized to issue up to a maximum of 2,929,481 shares of common stock for future issuance, plus up to an additional 4,967,172 shares upon termination of awards under the 2012 Plan. In addition, the 2013 Equity Plan is subject to increase annually on the first day of each of the Company’s fiscal years beginning with fiscal 2014, by an amount equal to the least of (i) 1,464,740 shares, (ii) 5% of the outstanding shares of common stock as of the last day of the immediately preceding fiscal year, or (iii) such other amount as determined by the Company's board of directors. Vested but unexercised options, under the 2013 Equity Plan, expire three months after termination of service with the Company. An additional 1,464,740 shares were authorized during the nine months ended September 30, 2017. As of September 30, 2017, outstanding awards under the 2013 Equity Plan and the 2012 Plan covered 3,588,518 shares and 343,037 shares of the Company's common stock, respectively.

The 2013 Equity Plan permits the granting of stock options, stock appreciation rights, restricted stock, restricted stock units ("RSUs"), performance units and performance shares to employees, directors and consultants of the Company.

Employee Stock Purchase Plan

In conjunction with the completion of its initial public offering in June 2013 (the "IPO"), the Company adopted the 2013 Employee Stock Purchase Plan (the “ESPP”). A maximum of 439,422 shares were initially authorized for future issuance. In addition, the ESPP is subject to increase annually on the first day of each of the Company’s fiscal years beginning with fiscal 2014, by an amount equal to the least of (i) 439,422 shares, (i) 1.5% of the outstanding shares of common stock as of the last day of the immediately preceding fiscal year, or (iii) such other amount as determined by the Company’s board of directors. Eligible employees can purchase shares of the Company’s common stock at a discount through payroll deductions of up to 15% of their eligible compensation, subject to plan limitations. Employees are able to purchase shares at 85% of the lower of the fair market value of the Company’s common stock (i) at the date of commencement of the offering period or (ii) at the last day of the purchase period. The ESPP provides for a 24-month offering period comprised of four purchase periods of approximately six months. The offering periods are scheduled to start on the first trading day on or after February 15 and August 15 of each year, except for the first offering period, which commenced on the first trading day upon the completion of the Company’s IPO, or June 12, 2013, and ended on August 17, 2015.

In accordance with the terms of the ESPP, an additional 439,422 shares were authorized for future issuance during the nine months ended September 30, 2017. The Company recorded stock-based compensation expense for its ESPP of $1.0 million and $4.9 million for the three and nine months ended September 30, 2017, respectively, and $1.4 million and $2.7 million for the three and nine months ended October 1, 2016, respectively. For the nine months ended September 30, 2017 there were two purchase periods that resulted in the issuance of 355,800 shares of the Company's common stock at a weighted average purchase price of $26.63 per share.

Stock Options

Stock options granted under the 2013 Equity Plan and formerly under the 2012 Plan (together, the “Equity Incentive Plans”), are generally subject to a four-year vesting period whereby stock options become 25% vested on the first anniversary of the grant date and then ratably monthly thereafter through the end of the vesting period. Vested stock

options may be exercised up to 10 years from the vesting commencement date. Under the 2012 Plan, vested but unexercised stock options expire 30 days after termination of service with the Company.

The following table summarizes the stock option activity under the Company’s Equity Incentive Plans:



	Number of Stock Options Outstanding		Weighted- Average Exercise Price		Weighted- Average Remaining Contractual Life (Years)	Aggregate Intrinsic Value (in Thousands)
Balance — December 31, 2016	1,391,171		$	21.19	6.39	$	35,076
Options granted	177,777		$	38.43
Options exercised	(75,904	)	$	12.95

Balance — September 30, 2017	1,380,957		$	23.53	6.17	$	27,239
Exercisable — September 30, 2017	927,460		$	17.64	5.69	$	22,728

Aggregate intrinsic value represents the difference between the exercise price of the awards and the Company’s fair value per share of $42.15 and $45.55 as of September 30, 2017 and December 31, 2016, respectively, for the total number of underlying options.

Restricted Stock Unit Activity

RSUs generally vest over a period of one to four years. RSU vesting dates are determined by the Company. The vesting is subject to the employee’s continuing service with the Company over that period. Until vested, RSUs do not have the voting or dividend participation rights of the Company’s common stock and the shares of the Company’s common stock underlying the awards are not considered issued and outstanding. The cost of RSUs is determined using the fair value of the Company’s common stock on the date of the grant.

The following table summarizes the RSU activity under the Company’s Equity Incentive Plans:



	Number of RSUs Outstanding		Weighted- Average Grant Date Fair Value		Weighted- Average Remaining Contractual Life (Years)	Aggregate Intrinsic Value (in Thousands)
December 31, 2016	2,466,049		$	26.66	1.39	$	112,329
RSUs awarded	1,500,180		$	35.66
RSUs released	(867,296	)	$	25.84
RSUs forfeited	(551,779	)	$	28.60
As of September 30, 2017	2,547,154		$	31.81	1.43	$	107,363

Aggregate intrinsic value for RSUs represents the Company’s fair market value per share of $42.15 and $45.55, as of September 30, 2017 and December 31, 2016, respectively, for the total number of underlying RSUs. The Company withheld shares totaling $12.6 million in value as a result of employee withholding taxes based on the value of the RSUs on their vesting dates for the nine months ended September 30, 2017. The total payments for the employees’ tax obligations to the taxing authorities are reflected as financing activities within the condensed consolidated statements of cash flows.

Performance-Based Restricted Stock Units

During the fiscal year ended December 31, 2016, the Company awarded 193,000 shares of performance-based RSUs. The vesting conditions of these awards were tied to the Company's fiscal 2016 revenue and operating income performance. These performance-based RSUs could have vested from 0% to 200% of the target grant, based on attainment of the performance goals. The target achievement percentage became known as of December 31, 2016. On December 31, 2016, the Company concluded that 149.5% of the target grants were likely to vest. For the three and nine months ended September 30, 2017, the Company recorded $0.2 million and $1.3 million, respectively, on a graded-vesting basis in stock-based compensation expense related to these performance-based RSU awards. As of September 30, 2017, there were 66,875 RSUs subject to performance-based vesting criteria.

Restricted Stock Award Activity

During the nine months ended September 30, 2017, the Company awarded 254,397 shares of restricted stock awards ("RSAs") at a weighted average grant date fair value of $30.72, of which 33,345 RSAs with a weighted average grant date fair value of $30.82 vested in the period.

RSA vesting dates are determined by the Company. The vesting is subject to the employee’s continuing service with the Company over that period. RSAs have the voting and dividend participation rights of the Company’s common stock. The cost of RSAs is determined using the fair value of the Company’s common stock on the date of the grant.

Performance-Based Restricted Stock Awards

During the nine months ended, the Company awarded 213,986 shares of performance-based RSAs at a weighted average grant date fair value of $32.01, of which 6,166 awards with a weighted average grant date fair value of $23.78 vested. The vesting conditions of 166,570 of these awards are tied to the Company's fiscal 2017 revenue and operating income performance. These performance-based RSAs could vest from 0% to 200% of the target grant, based on attainment against the performance goals.

Stock-Based Compensation Expense

The fair value of the option awards and ESPP purchase rights granted and the assumptions used in the Black-Scholes option pricing model are summarized as follows:

The following table summarizes the stock-based compensation expense recorded in the Company’s condensed consolidated statements of operations (in thousands):



	Three Months Ended				Nine Months Ended
	September 30, 2017		October 1, 2016		September 30, 2017		October 1, 2016
Cost of revenue	$	333	$	519	$	1,802	$	1,527

Total stock-based compensation expense	$	10,973	$	10,104	$	39,991	$	28,884

As of September 30, 2017 and December 31, 2016, there was $0.4 million and $0.2 million of capitalized stock-based compensation costs, respectively, within the Company's inventory balance.

As of September 30, 2017, unrecognized compensation expense related to stock options, RSUs, RSAs, PSUs, PSAs and ESPP purchase rights was $4.7 million, $44.4 million, $4.1 million, $0.8 million, $0.6 million and $4.5 million, respectively.

7. Defined Contribution Plans

The Company’s contributions to its 401(k)-defined contribution plan, which are expensed immediately as compensation costs, were $0.9 million and $0.6 million for the three months ended September 30, 2017 and October 1, 2016, respectively and $2.8 million and $1.7 million for the nine months ended September 30, 2017 and October 1, 2016, respectively.

8. Income Tax

The Company recorded an income tax benefit of $1.5 million and $9.6 million for the three and nine months ended September 30, 2017, respectively, and an income tax provision of $4.0 million and an income tax benefit of $23.3 million for the three and nine months ended October 1, 2016, respectively. The income tax benefit for the three and nine months ended September 30, 2017 was primarily related to the Company's year-to-date pre-tax loss and a tax benefit related to stock-based compensation. As of September 30, 2017, the Company considered all positive and negative evidence in making a determination that the Company will more likely than not be able to utilize its U.S. deferred tax assets. Such evidence included, among others, the Company's history of profitability, jurisdictional income recognition trends, forecasted income by jurisdiction and maintaining three years of cumulative taxable income in the U.S. federal tax jurisdiction as of September 30, 2017. Therefore, the Company determined that there is sufficient positive evidence to conclude that it is more likely than not that it will utilize its U.S. deferred tax assets. Included in the net deferred tax asset balance is a $6.7 million valuation allowance that relates to research and development credits in a jurisdiction with a history of credits in excess of taxable profits.

The Company adopted the accounting standard update related to Improvements to Employee Share-Based Payment Accounting, which amends Compensation – Stock Compensation in the first quarter of fiscal 2017. As a result, the Company recorded a deferred tax asset of $7.6 million for the previously unrecognized excess tax benefits with an adjustment of $7.1 million and $0.5 million to retained earnings and a valuation allowance for a certain jurisdiction, respectively, on the accompanying condensed consolidated balance sheet. Additionally, the adoption resulted in net excess tax benefits in the Company's provision for income taxes of $4.8 million on its condensed consolidated statements of operations for the nine months ended September 30, 2017.

The Company files annual income tax returns in multiple tax jurisdictions worldwide. A number of years may lapse before an uncertain tax position is audited and finally resolved. While it is typically difficult to predict the final outcome or the timing of resolution of any particular uncertain tax position, the Company believes its reserves for income taxes reflect the most likely outcomes. The Company adjusts these reserves, as well as the related interest, in light of changing facts and circumstances. Settlement of any particular position would likely require the use of cash.

As of September 30, 2017, changes to the Company's uncertain tax positions in the next 12 months that are reasonably possible are not expected to have a material impact on the Company's financial position or results of operations. The Company recognizes interest and penalties related to uncertain tax positions as part of the income tax provision. To date, no such interest and penalties have been accrued.

9. Net Income (Loss) per Share

Basic net income (loss) per share is computed using the weighted average number of common shares outstanding for the period, excluding unvested restricted stock.

Due to the net loss incurred in the nine months ended September 30, 2017, potential dilutive securities were excluded from the calculation of diluted net loss per share attributable to common stockholders for such period as their effect was anti-dilutive.

Diluted net income (loss) per share is computed based upon the weighted average common shares outstanding for the period plus dilutive potential common shares, including unvested stock awards and stock options using the treasury stock method.

The following table presents the computation of basic and diluted net income (loss) per share attributable to common stockholders (in thousands, except per share data):



	Three Months Ended				Nine Months Ended
	September 30, 2017		October 1, 2016		September 30, 2017			October 1, 2016

Net income (loss)	2,178		6,079		(7,397		)	43,009
Denominator:
Weighted average shares used for basic net income (loss) per share computation	37,196		35,770		36,885			35,171

Weighted average shares used for diluted net income (loss) per share computation	39,574		38,113		36,885			37,341
Net income (loss) per share attributable to common stockholders:
Basic	$	0.06	$	0.17	$	(0.20	)	$	1.22
Diluted	$	0.06	$	0.16	$	(0.20	)	$	1.15

(1) Includes RSUs, performance-based RSUs, RSAs and performance-based RSAs

The weighted average number of shares outstanding used in the computation of diluted net income (loss) per share does not include the effect of the following shares of potentially outstanding common stock because the effect would have been anti-dilutive for the periods presented (in thousands):



	Three Months Ended		Nine Months Ended
	September 30, 2017	October 1, 2016	September 30, 2017	October 1, 2016
Equity awards to purchase common stock	258	20	310	74

10. Segment Information

The Company currently has one operating segment. The Company considers operating segments to be components of the Company’s business for which separate financial information is available that is evaluated regularly by the Company’s chief operating decision maker in deciding how to allocate resources and in assessing performance. The Company has determined that the chief operating decision maker is its chief executive officer. The chief executive officer reviews financial information presented on a consolidated basis for purposes of allocating resources and evaluating financial performance. Accordingly, the Company has determined that it has a single operating and reportable segment.

11. Subsequent Event

On October 26, 2017, the Company entered into an agreement and plan of merger (“Merger Agreement”) with Ginsberg Holdco, Inc. (“Newco”) and Ginsberg Merger Sub, Inc., a wholly-owned subsidiary of Newco (“Merger Sub”), providing for the merger of Merger Sub with and into the Company (the “Merger”), with the Company surviving the Merger as a wholly-owned subsidiary of Newco. Newco and Merger Sub were formed by Elliott Associates, L.P. and Elliott International, L.P. (the “Elliott Funds”), funds affiliated with Elliott Management Corporation (“Elliott”). Capitalized terms not otherwise defined have the meanings set forth in the Merger Agreement.

At the Effective Time of the Merger, each share of common stock of the Company (the Company Common Stock) issued and outstanding as of immediately prior to the Effective Time (including Shares of Restricted Stock and excluding Dissenting Shares) will be cancelled and extinguished and automatically converted into the right to receive cash in an amount equal to $38.50, without interest thereon (the Per Share Price). Company Options and awards generally will be cancelled and converted into the right to receive the Per Share Price, less, in the case of Company Options, the exercise price per share.

Newco has secured committed financing, consisting of a combination of equity financing to be provided by the Elliott Funds and debt financing from Jefferies Finance LLC, the aggregate proceeds of which will be sufficient for Newco to pay the aggregate merger consideration and all related fees and expenses. Newco has committed to use its reasonable best efforts to obtain the debt financing on the terms and conditions described in the debt commitment letter entered into in connection with the Merger Agreement on October 26, 2017. The transaction is not subject to any financing condition.

Consummation of the Merger is subject to customary closing conditions, including, without limitation, the absence of certain legal impediments, the expiration or termination of the required waiting periods under the Hart-Scott-Rodino

Antitrust Improvements Act of 1976, as amended, and approval by the Company’s stockholders and a minimum cash condition.

The Company has made customary representations and warranties in the Merger Agreement and has agreed to customary covenants regarding the operation of the business of the Company and its Subsidiaries prior to the Effective Time. The Company is also subject to customary restrictions on its ability to solicit alternative acquisition proposals from third parties and to provide non-public information to, and participate in discussions and engage in negotiations with, third parties regarding alternative acquisition proposals, with certain exceptions for alternative acquisition proposals that are or are reasonably likely to lead to Superior Proposals.

The Merger Agreement contains certain termination rights for the Company and Newco. Upon termination of the Merger Agreement in connection with the Company accepting a Superior Proposal or due to the Company Board’s change or withdrawal of its recommendation of the Merger, the Company will be required to pay Newco a termination fee of $47.2 million. This termination fee will also be payable if the Merger Agreement is terminated because the Company’s stockholders did not vote to adopt the Merger Agreement(or the termination date for the transaction (as described below) occurs before the stockholder approval is obtained) and prior to such termination, a proposal to acquire at least 50% of the Company’s stock or assets is publicly announced (or delivered to the Company’s Board of Directors) and the Company enters into an agreement for, or completes, an alternative acquisition transaction within one year of termination.

Upon termination of the Merger Agreement under other specified circumstances, Newco will be required to pay the Company a termination fee of $94.4 million. The termination fee will become payable by Newco if it fails to consummate the Merger after certain conditions are met, if Newco breaches its representations, warranties or covenants in a manner that would cause the related closing conditions to not be met, or if either party terminates because of the termination date, and at the time of such termination, the Company was otherwise entitled to terminate the Merger Agreement for either of the above reasons. The Elliott Funds have provided the Company with a limited guaranty in favor of the Company (the “Limited Guarantee”). In the aggregate, the Limited Guarantee guarantees the payment of the termination fee payable by Newco and certain reimbursement obligations that may be owed by Newco to the Company pursuant to the Merger Agreement. The Merger Agreement also provides that, under certain conditions, either party may specifically enforce the other party’s obligations under the Merger Agreement.

In addition to the foregoing termination rights, and subject to certain limitations, the Company or Newco may terminate the Merger Agreement if the Merger is not consummated by April 25, 2018. The transaction is expected to close in the first quarter of fiscal 2018.

Overview

We have developed innovative solutions that deliver pervasive, dynamic and intelligent visibility and control of data-in-motion traversing enterprise, federal and service provider networks. Our Visibility Platform consists of a distributed system of nodes (that in combination establish a Visibility Fabric) that enable an advanced level of visibility, modification and control of network traffic. Our Visibility Platform is comprised of physical appliances and virtual nodes that can be deployed in data centers, central offices, remote sites, virtual environments, private clouds, public clouds and hybrid clouds. We believe our Visibility Platform enables organizations to significantly improve their ability to secure, manage and understand critical data-in-motion traversing their infrastructure. Enterprise and federal organizations can enhance their cyber-security posture by leveraging the power of network visibility to achieve a pervasive view within the perimeter of their IT infrastructure. Furthermore, IT departments can significantly increase the effectiveness, efficiency and performance of their network management, analysis and compliance tools. Using our Visibility Platform, mobile service providers can gain subscriber-level awareness across their infrastructure enabling them to improve services, increase revenue generating opportunities and reduce operational costs.

We generate product revenue primarily from sale of perpetual software licenses installed on purpose-built physical Visibility Fabric appliances through channel partners, including distributors and resellers, as well as directly to end-user customers. We provide our channel partners with marketing assistance, technical training and support. Typically, we derive 80% or more of our revenue through channel partners.

We generate service revenue primarily from the sales of maintenance and support services for our products. Starting in the quarter ended September 26, 2015, we began to sell first-year maintenance and support as an additional offering. Prior to that time, the first year of maintenance and support services was generally bundled with the initial contract to purchase our products. Following expiration of this one-year contract, our end-user customers typically purchase maintenance and support contracts that generally have one-year terms.

Our revenue decreased to $79.2 million in the three months ended September 30, 2017 from $83.5 million in the three months ended October 1, 2016. As of September 30, 2017, we had increased our cumulative customer count to approximately 2,600, as compared to over 2,200 as of October 1, 2016. Our net income was $2.2 million for the three months ended September 30, 2017 compared to net income of $6.1 million for the three months ended October 1, 2016. We generated cash from operations of $21.5 million for the nine months ended September 30, 2017 compared to $31.2 million for the nine months ended October 1, 2016. We operate as a single reportable segment.

Fiscal year 2016 was a 53-week fiscal year, with the first quarter being a 14-week quarter and each subsequent quarter being a 13-week quarter. Fiscal 2017 is a 52-week fiscal year ending on December 30, 2017, with all quarters being 13 weeks.

Recent Developments

On October 26, 2017, we entered into the Merger Agreement with Newco and Merger Sub, each an affiliate of Elliot, providing for the Merger of Merger Sub with and into the Company, with the Company surviving the Merger as a wholly-owned subsidiary of Newco. Newco will acquire 100% of the Company's common stock for $38.50 per share

in cash (the “Merger Consideration”), for a total value of approximately $1.6 billion. At the Effective Time, each Company Option outstanding immediately prior to the Effective Time (whether vested or unvested) will be cancelled and converted into the right to receive an amount in cash, without interest, equal to the product of (x) the excess, if any, of (A) the Merger Consideration over (B) the exercise price per share of such Company Option multiplied by (y) the total number of Shares issuable upon the exercise in full of such Company Option. At the Effective Time, each Restricted Stock Unit outstanding immediately prior to the Effective Time will be cancelled and converted into the right to receive an amount in cash, without interest, equal to the product of (x) the Merger Consideration multiplied by (y) the total number of Shares subject to such award of Restricted Stock Units. With respect to any Shares of Performance Restricted Stock or Performance Restricted Stock Units, the achievement of all performance goals applicable thereto will be based on actual performance as set forth in the applicable agreements governing the award, any earned portion of such award will be eligible to be cancelled and converted into the right to receive an amount in cash as described above with respect to Company Common Stock or Restricted Stock Units, as applicable, and any unearned portion of such award shall be cancelled without any cash payment or other consideration being made in respect thereof.

We anticipate that the transaction will be consummated in the first quarter of 2018. We did not incur significant costs related to the Merger during the third quarter of 2017 while we anticipate to incur significant costs, expenses, and fees for professional services and other transaction costs in connection with the Merger in future periods.

Key Performance Indicators of Our Business

We monitor a variety of key performance indicators to help us evaluate growth trends, establish budgets, measure the effectiveness of our sales and marketing efforts and assess operational efficiencies. These key performance indicators include (dollars in thousands):

Revenue. We monitor our revenue to assess the acceptance of our products and services by our end-user customers and growth in the markets we serve.

Gross margin. We monitor our gross margin to assess the impact on our current and forecasted financial results from any changes to the pricing, mix and costs of products we are selling to our customers.

Income from operations. We monitor our income from operations to assess how effectively we are conducting our operations as well as controlling our expenses, which are primarily driven by headcount because we have an outsourced production model.

Deferred service revenue. Our deferred service revenue consists of the unamortized portion of service revenue from maintenance and support contracts. We monitor our deferred service revenue balance because it represents a significant portion of the revenue we will recognize in future periods. We assess the annual change in our deferred service revenue balance which, taken together with revenue, is an indication of sales activity year over year.

Financial Overview

Revenue

We generate revenue from the sale of products and related services, including maintenance and support. We present revenue net of discounts, rebates and sales taxes. Our revenue is comprised of the following:

Product revenue. We generate product revenue primarily from sales of perpetual software licenses installed on purpose-built physical appliances that establish a Visibility Fabric. We generally recognize product revenue at the time of product delivery, provided all other revenue recognition criteria have been met. We expect our product revenue as

a percentage of revenue to vary from quarter-to-quarter based on, among other things, the timing of orders, the delivery of products, and seasonal and cyclical factors discussed under the section titled “Results of Operations.”

We have experienced seasonality in the sale of our products. The first quarter of each year is usually our lowest revenue quarter during the year and product revenue typically declines sequentially from the prior fourth quarter. We generally expect and normally experience an increase in sales in the second half of the year relative to the first half, primarily due to the buying habits of many of our end-user customers as budgets for annual capital purchases are being fully utilized. The fiscal year-ending September 30 of the U.S. Federal government has in certain years resulted in increased selling momentum for certain transactions in our third quarter.

Over time we expect our product revenue to increase as we continue to extend our product portfolio, add new end-user customers and expand the volume of shipments to our current end-user customers.

Service revenue. We generate service revenue primarily from sales of maintenance and support contracts, which may be bundled with sales of products, and from sales and subsequent renewals of maintenance and support contracts. We offer tiered maintenance and support services under our renewable, fee-based maintenance and support contracts, which include technical support, bug fixes, patches and unspecified upgrades on a when-and-if-available basis. We recognize service revenue ratably over the duration of the contract, which is typically one year and can be for multiple years depending on the contract. As a result, the impact on service revenue will lag any shift in product revenue because product revenue is recognized when a product is sold and revenue criteria are satisfied, whereas service revenue is recognized ratably over the contract term. We expect our service revenue to increase as we expand our installed base by selling more products and support contracts, and adding more end-user customers.

Cost of revenue

Our cost of revenue consists of cost of product revenue and cost of service revenue. The number of employees attributable to the cost of revenue increased to 54 as of September 30, 2017, compared to 47 as of October 1, 2016.

Cost of product revenue. Cost of product revenue is comprised primarily of the costs associated with manufacturing our products, including third-party hardware manufacturing costs; personnel costs for salary, benefits, bonuses and stock-based compensation expense; shipping costs; allocated costs of facilities and information technology; any inventory write-downs; warranty costs and other related expenses. We expect cost of product revenue to increase in connection with the anticipated increase in product revenue.

Cost of service revenue. Cost of service revenue is comprised primarily of personnel costs for salary, benefits, bonuses and stock-based compensation expense related to our customer support organization, as well as allocated costs of facilities, information technology and engineering. We expect cost of service revenue to increase in connection with the anticipated increase in service revenue.

Gross profit and gross margin

Gross profit has been and will continue to be affected by a variety of factors including shipment volumes, changes in the mix of products and services sold, changes in our product costs including any inventory write-downs, new product introductions and upgrades to existing products, changes in customer mix, changes in pricing and the extent of customer rebates and incentive programs. We expect our gross margin to fluctuate over time depending on a variety of factors, including those described above.

Operating expenses

Operating expenses consist of research and development, sales and marketing and general and administrative expenses. Personnel costs comprise a significant component of our operating expenses, and consist of salaries, benefits, bonuses and stock-based compensation expense; and with respect to our sales organization, personnel costs also include sales commissions. The number of employees attributable to our operating expenses increased to 732 employees as of September 30, 2017, compared to 588 employees as of October 1, 2016.

Research and development

Our research and development efforts consist primarily of software development and are focused on technical research, new product development and additional functionality for our existing products, and on-going activities to sustain previously developed products. Research and development expenses consist primarily of personnel costs, and to a lesser extent, prototype materials, allocated costs of facilities and information technology and product certification. We expense research and development costs as incurred.

Sales and marketing

Sales and marketing expenses are the largest component of our operating expenses and consist primarily of personnel costs, as well as travel expenses, trade shows, marketing and promotional activities, and allocated costs of facilities and information technology. We sell our products through our global sales organization, which is divided into three geographic regions: (i) the Americas (which includes the United States, Canada and Latin America), (ii) Europe, the Middle East and Africa (EMEA) and (iii) Asia Pacific. We expect our sales and marketing expenses to increase as we expand our sales and marketing efforts internationally and domestically to help drive increased revenue.

General and administrative

General and administrative expenses consist of personnel costs and allocated costs of facilities and information technology related to our executive, finance, human resources and legal functions, as well as professional services costs. Professional services costs consist primarily of outside legal and accounting services. We have incurred expenses as a result of operating as a public company, including costs to comply with the rules and regulations applicable to companies listed on a national securities exchange and costs related to compliance and reporting obligations.

Interest income and other income (expense), net

Interest income consists primarily of income earned on our invested cash, cash equivalents and short-term investments. Historically, interest income has not been material, and is not expected to be material despite our increased level of invested cash.

Other income (expense), net consists primarily of foreign currency exchange gains (losses) related to transactions denominated in currencies other than the U.S. dollar, which have not been material to date.

Income Tax (Provision) Benefit

Our income tax benefit was $1.5 million and $9.6 million for the three and nine months ended September 30, 2017, respectively, and we had a $4.0 million income tax provision and a $23.3 million income tax benefit for the three and nine months ended October 1, 2016, respectively. The income tax benefit for the three and nine months ended September 30, 2017 was primarily related to our year-to-date pre-tax loss and a tax benefit related to stock-based compensation. As of September 30, 2017, we concluded that it is more likely than not that we will be able to realize our deferred tax assets in the foreseeable future except for research and development credits in a jurisdiction with a history of credits in excess of taxable profits. We will continue to assess the need for the valuation allowance on a quarterly basis.

Stock-based compensation expense and other compensation charges

Stock-based compensation expense was $11.0 million and $40.0 million for the three and nine months ended September 30, 2017, respectively, compared to $10.1 million and $28.9 million for the three and nine months ended October 1, 2016, respectively. The increase in stock-based compensation expense was primarily due to headcount increases and our election to account for forfeitures as they occur under the recently adopted accounting guidance. As of September 30, 2017, total unrecognized stock-based compensation expense was $59.1 million (see Note 6 "Stockholders' Equity" included in Part I, Item I).

Product revenue decreased $8.0 million and $16.7 million in the three and nine months ended September 30, 2017, respectively, as compared to the same prior year periods, driven primarily by decreases in North American public sector revenue, partially offset by revenue increases in the EMEA and APAC regions.

Service revenue increased $3.7 million and $8.8 million in the three and nine months ended September 30, 2017, respectively, as compared to the same prior year periods, primarily due to the growth in our installed base of end-user customers under maintenance and support contracts.

Three Months Ended September 30, 2017 Compared to Three Months Ended October 1, 2016

Total gross margin was 82% in the three months ended September 30, 2017 compared to 83% in the three months ended October 1, 2016. The slight decline in gross margin was primarily due to higher product discounting, partially offset by a more favorable mix shift to higher margin service and software revenue.

Product gross margin was 78% in the three months ended September 30, 2017 compared to 80% gross margin in the three months ended October 1, 2016, primarily due to higher product discounting in the three months ended September 30, 2017.

Service gross margin was 89% in the three months ended September 30, 2017 compared to 91% in the three months ended October 1, 2016, primarily due to increased headcount investments to better support customers under maintenance and support contracts.

Nine Months Ended September 30, 2017 Compared to Nine Months Ended October 1, 2016

Total gross margin was 81% in the nine months ended September 30, 2017, compared to 82% in the nine months ended October 1, 2016. The slight decline in gross margin was primarily due to higher product discounting, partially offset by a more favorable mix shift to higher margin service and software revenue.

Product gross margin was 77% in the nine months ended September 30, 2017 compared to 78% gross margin in the nine months ended October 1, 2016, primarily due to higher product discounting in the nine months ended September 30, 2017.

Service gross margin was 89% in the nine months ended September 30, 2017 compared to 91% in the nine months ended October 1, 2016, primarily due to increased headcount investments to better support customers under maintenance and support contracts.

Three Months Ended September 30, 2017 Compared to Three Months Ended October 1, 2016

Research and development expenses increased $0.5 million in the three months ended September 30, 2017 as compared to the same prior year period. This increase was primarily driven by increased payroll, payroll tax and contractor-related expenses of $1.4 million, and increased stock-based compensation and related payroll tax expenses of $0.6 million, partially offset by a $1.3 million reduction in bonus expense. The remaining research and development expense increase was primarily driven by higher IT expenses, depreciation, and facilities-related expenses required to support a larger research and development team, partially offset by a decrease of $1.0 million in development related expenses.

Sales and marketing expenses increased $2.9 million in the three months ended September 30, 2017 as compared to the same prior year period. This increase was primarily driven by $1.3 million of additional personnel costs, which were primarily comprised of increased payroll, payroll tax and contractor-related expenses of $3.1 million and severance expenses of $0.8 million related to a restructuring, partially offset by $2.2 million of decreased commission expense and $0.5 million of decreased bonus expense. The remaining sales and marketing expense increase was primarily driven by a $0.7 million increase in marketing costs, a $0.5 million increase in IT and facilities allocations, and higher travel and entertainment expense of $0.3 million.

General and administrative expenses increased $1.8 million in the three months ended September 30, 2017 as compared to the same prior year period. This increase was primarily driven by $1.5 million of expenses related to non-routine shareholder matters expenses, increased payroll, payroll tax and contractor-related expenses of $0.8 million and increased stock-based compensation and related payroll tax expenses of $0.2 million, partially offset by a $0.9 million reduction in bonus expense.

Nine Months Ended September 30, 2017 Compared to Nine Months Ended October 1, 2016

Research and development expenses increased $8.5 million in the nine months ended September 30, 2017 as compared to the same prior year period. This increase was primarily driven by $6.9 million of additional personnel costs , primarily comprised of increased stock-based compensation and related payroll tax expenses of $4.7 million, and increased payroll, payroll tax and contractor-related expenses of $4.5 million, partially offset by a $2.3 million reduction in bonus expense, a $1.0 million increase in facilities-related and IT-related expenses required to support a larger research and development team, and a $0.7 million increase in depreciation expense.

Sales and marketing expenses increased $16.8 million in the nine months ended September 30, 2017 as compared to the same prior year period. This increase was primarily driven by $11.3 million of additional personnel costs, which were primarily comprised of increased payroll, payroll tax and contractor-related expenses of $10.9 million, increased stock-based compensation and related payroll tax expenses of $4.3 million and severance expenses of $0.8 million related to a restructuring, partially offset by a $4.0 million decrease in commission expense and a $0.8 million decrease in bonus expense. The remaining sales and marketing expense increase was primarily driven by a $1.4 million increase IT-related and facilities-related costs to support a larger sales and marketing team, a $1.2 million increase in expenses related to internal sales events, a $1.2 million increase in travel expenses and $0.8 million of software license purchases.

General and administrative expenses increased $4.0 million in the nine months ended September 30, 2017 as compared to the same prior year period. This increase was primarily driven by $3.6 million of additional personnel costs, primarily comprised of a $2.2 million increase in payroll, payroll taxes and contractor-related expenses, and a $1.8 million increase in stock-based compensation and related payroll tax expenses, partially offset by a $1.7 million reduction in bonus expense and $2.0 million of expenses related to in non-routine shareholder matters and other consulting expenses, partially offset by a $0.6 million reduction in use tax.

Income Tax (Provision) Benefit



	Three Months Ended									Nine Months Ended
	September 30, 2017		October 1, 2016			$ Change		% Change		September 30, 2017		October 1, 2016		$ Change			% Change
	(dollars in thousands)									(dollars in thousands)
Income tax (provision) benefit	$	1,531	$	(3,999	)	$	5,530	(138	)%	$	9,576	$	23,321	$	(13,745	)	(59	)%

We account for income taxes under the asset and liability approach. This process involves estimating the actual current tax exposure, including assessing the risks associated with tax audits, and assessing temporary differences resulting from the different treatment of items for tax and accounting purposes. These differences result in deferred tax assets and liabilities. We assess the likelihood that our deferred tax assets will be recovered from future taxable income and, to the extent we believe that recovery is not likely, we establish a valuation allowance. Significant judgment is required in determining whether the valuation allowance should be recorded against deferred tax assets. In assessing the need for a valuation allowance, we consider all available evidence including past operating results and estimates of future forecasted taxable income or losses.

We had an income tax benefit of $1.5 million and $9.6 million for the three and nine months ended September 30, 2017, respectively, compared to an income tax provision of $4.0 million and an income tax benefit of $23.3 million for the three and nine months ended October 1, 2016, respectively. The income tax benefit recorded in the three and nine months ended September 30, 2017 was primarily related to our year-to-date pre-tax loss and a tax benefit related to stock-based compensation. The income tax benefit for the nine months ended October 1, 2016 represents the release of $30.5 million of existing valuation allowance against our U.S. deferred tax assets and additional foreign income tax expense.

In making a determination whether to set up a valuation allowance or not, we considered all available evidence, both positive and negative. Such evidence included, but was not limited to, our history of profitability and losses, jurisdictional income recognition trends, pre-tax losses adjusted for certain other items, and forecasted income by jurisdiction. Based on the above evidence, we determined that it is more likely than not that we will utilize our U.S. deferred tax assets except for research and development credits in a jurisdiction with a history of credits in excess of taxable profits.

Liquidity and Capital Resources

As of September 30, 2017, our principal sources of liquidity, which consisted of cash, cash equivalents and short-term investments of $264.6 million, were held primarily in the United States. Our liquidity requirements are primarily to fund our working capital and operating expenses. As of September 30, 2017, we had no material commitments for capital expenditures.

Our future capital requirements will depend on many factors, including our results of operations and the expansion of our research and development, sales and marketing and general and administrative functions. Based on our current operating plan, we believe our existing cash, cash equivalents and investments, combined with cash generated from operations, will be sufficient to fund our working capital and operating expenses for at least the next 12 months. If we require additional capital resources to grow our business internally or to acquire complementary technologies and businesses at any time in the future, we may seek to sell additional equity, or raise funds through debt financing or other sources. The sale of additional equity could result in additional dilution to our stockholders. If we raise additional funds by obtaining loans from third parties, the terms of those financing arrangements may include negative covenants or other restrictions on our business that could impair our operating flexibility, and would also require us to incur cash interest expense. We can provide no assurance that additional financing will be available at all or, if available, that we would be able to obtain financing on terms favorable to us.

Cash flows

The following table summarizes our cash flows for the periods indicated (in thousands):



	Nine Months Ended
	September 30, 2017			October 1, 2016⁽¹⁾
Net cash provided by (used in) operating activities	$	21,501		$	31,169
Net cash provided by (used in) investing activities	$	5,734		$	(5,027	)
Net cash provided by (used in) financing activities	$	(2,166	)	$	9,199

⁽¹⁾Reflects the impact of the adoption of the accounting standard update related to Improvements to Employee Share-Based Payment Accounting, which amends Compensation - Stock Compensation.

Cash flows from operating activities

Our cash provided by operating activities is generated from sales of our products and, to a lesser extent, by upfront payments from customers under maintenance and support contracts. Our primary uses of cash from operating activities have been for personnel-related expenses, manufacturing costs, expenses related to marketing and promotional activities and costs related to our facilities. Our cash flows from operating activities will continue to be affected principally by our working capital requirements and increased spending on personnel, facilities and sales and marketing activities to meet our anticipated business growth.

In the nine months ended September 30, 2017, our operating activities provided cash of $21.5 million. This was primarily due to timing of collection of our accounts receivable and a higher concentration of service bookings with upfront payment from customers.

Cash flows from investing activities

Net cash provided by investing activities of $5.7 million for the nine months ended September 30, 2017 was primarily attributable to maturities of short-term investments of $96.0 million, mostly offset by $78.1 million used for purchases of short-term investments and $12.2 million used for capital expenditures for property and equipment to support our business.

Cash flows from financing activities

Net cash used in financing activities of $2.2 million for the nine months ended September 30, 2017 was primarily due to $12.6 million of tax payments upon vesting of restricted stock units, mostly offset by proceeds of $9.4 million from the issuance of common stock pursuant to our ESPP and $1.0 million from stock option exercises.

Contractual Obligations

As of September 30, 2017, we had not entered into any material additional contractual obligation beyond those disclosed in the Annual Report on Form 10-K as of December 31, 2016. As of September 30, 2017, we had no material changes in tax liabilities recorded related to uncertain income tax positions beyond those disclosed in the Annual Report on Form 10-K as of December 31, 2016.

Off-Balance Sheet Arrangements

We do 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 purposes.

Indemnification Obligations

Under the indemnification provisions of our standard sales related contracts, we agree to defend our customers against third-party claims asserting infringement of certain intellectual property rights, which may include patents, copyrights, trademarks, or trade secrets, and to pay judgments entered on such claims. Our exposure under these indemnification provisions is generally limited to the total amount paid by our customer under the agreement. However, certain agreements include indemnification provisions that could potentially expose us to losses in excess of the amount received under the agreement. We have not incurred any costs as a result of such indemnifications and have not accrued any liabilities related to such obligations in our consolidated financial statements. In addition, we indemnify our officers, directors, and certain key employees while they are serving in good faith in the company capacities. To date, there have been no claims under any indemnification provisions.

Recent Accounting Pronouncements

See Note 2, Summary of Significant Accounting Policies, in Notes to Condensed Consolidated Financial Statements in Part I - Item 1 - Financial Statements (unaudited) of this Report, for a full description of recent accounting pronouncements, including the expected dates of adoption and effects on the consolidated financial statements, which is incorporated herein by reference.

Critical Accounting Policies and Estimates

Our condensed consolidated financial statements are prepared in accordance with GAAP. The preparation of these condensed financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, operating expenses and related disclosures. On an ongoing basis, we evaluate our estimates and assumptions. We base our estimates and assumptions on historical experience and on various other factors that we believe to be reasonable under the circumstances. Accordingly, actual results could differ significantly from the estimates made by our management. To the extent that there are material differences between our estimates and actual results, our future financial statement presentation, financial condition, results of operations and cash flows would be affected.

An accounting policy is considered to be critical if the nature of the estimates or assumptions is material due to the levels of subjectivity and judgment necessary to account for highly uncertain matters or the susceptibility of such matters to change, and the effect of the estimates and assumptions on financial condition or operating performance is material. The accounting policies we believe to reflect our more significant estimates, judgments, and assumptions and are most critical to understanding and evaluating our reported financial results are as follows:


•	Revenue Recognition;


•	Stock-Based Compensation;


•	Inventory Valuation;


•	Warranty Reserves; and


•	Income Taxes and the release of our Valuation Allowance (see Note 8 Income Tax included in Part I, Item I).

There have been no material changes to our critical accounting policies and estimates as compared to the critical accounting policies and estimates described in our Annual Report on Form 10-K for the fiscal year ended December 31, 2016.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

We are exposed to market risks in the ordinary course of our business. Market risk represents the risk of loss that may impact our financial position due to adverse changes in financial market prices and rates. We do not hold or issue financial instruments for trading purposes.

Foreign currency exchange rate sensitivity

Our functional currency is the U.S. dollar. Most of our revenue, cost of revenue and operating expenses are denominated in U.S. dollars, and therefore our revenue is not currently subject to significant foreign currency risk. Our operating expenses are transacted in the currencies of the countries in which our operations are located, which are primarily in the Americas, Europe, the Middle East, and Africa, and the Asia-Pacific region. Our condensed consolidated statements of operations, comprehensive income (loss) and cash flows are, therefore, subject to fluctuations due to changes in foreign currency exchange rates and may be adversely affected in the future due to changes in foreign exchange rates. To date, we have not entered into any hedging arrangements with respect to foreign currency risk or other derivative financial instruments. In the nine months ended September 30, 2017 and October 1, 2016, the effect of a hypothetical 10% change in foreign currency exchange rates applicable to our business would not have had a material impact on our condensed consolidated financial statements.

Interest rate sensitivity

We had cash, cash equivalents and short-term investments of $264.6 million as of September 30, 2017. We hold our cash, cash equivalents and short-term investments for working capital purposes. Our cash and cash equivalents are primarily held in cash deposits and money market funds. We have invested a portion of our funds in short-term investments that are focused on preservation of capital and supporting our liquidity requirements. Our short-term investments are held in U.S. Treasury securities, U.S. agency debt securities and corporate debt securities. Due to the short-term nature of these instruments, we believe that we do not have any material exposure to changes in the fair value of our investment portfolio as a result of changes in interest rates. Declines in interest rates, however, would reduce future interest income. For the nine months ended September 30, 2017 and October 1, 2016, the effect of a

hypothetical 10% increase or decrease in overall interest rates would not have had a material impact on the fair value of our available-for-sale securities or our interest income.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

The phrase “disclosure controls and procedures” refers to controls and other procedures designed to ensure that information required to be disclosed in our reports filed or submitted under the Securities Exchange Act of 1934, as amended, or the Exchange Act, such as this Quarterly Report on Form 10-Q, is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the U.S. Securities and Exchange Commission, or the SEC. Disclosure controls and procedures are also designed to ensure that such information is accumulated and communicated to our management, including our Chief Executive Officer, or the CEO, and our Chief Financial Officer, or the CFO, as appropriate to allow timely decisions regarding required disclosure.

Under the supervision and with the participation of our management, including our CEO and CFO, we carried out an evaluation of the effectiveness of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, as of September 30, 2017, the end of the fiscal period covered by this Quarterly Report on Form 10-Q, or the Evaluation Date. Based on this evaluation, our CEO and CFO concluded that, as of the Evaluation Date, our disclosure controls and procedures were effective such that the information required to be disclosed in our SEC reports (i) is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms and (ii) is accumulated and communicated to our management, including our CEO and CFO, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Control Over Financial Reporting

There has been no change in our internal control over financial reporting identified in connection with our evaluation required by paragraph (d) of rules 13a-15 and 15d-15 under the Exchange Act that occurred during the third quarter of fiscal 2017 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

On January 27, 2017, a purported shareholder class action was filed in the United States District Court for the Northern District of California against us and three of our current and former officers, Rodriguez v. Gigamon Inc., et al., Case No. 17-cv-00434 (N.D. Cal. filed Jan. 27, 2017). The plaintiff alleges that we made false and misleading statements about our business, operations and prospects, including statements about our guidance for the fourth quarter of 2016. The complaint asserts claims for violations of Section 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended and SEC Rule 10b-5 on behalf of all persons and entities who acquired our securities between October 27, 2016 and January 17, 2017. The complaint, as amended, seeks unspecified monetary damages, attorneys' fees and costs and other relief. We believe this lawsuit is without merit and intend to defend against it vigorously.

In addition, we may, from time to time, be subject to various legal proceedings, claims and litigation arising in the ordinary course of business. Other than that disclosed above, we do not believe we are a party to any currently pending legal proceedings the outcome of which would be expected to have a material adverse effect on our financial position, results of operations or cash flows.

There can be no assurance that existing or future legal proceedings arising in the ordinary course of business or otherwise will not have a material adverse effect on our financial position, results of operations or cash flows.

Item 1A. Risk Factors

Investing in our common stock involves a high degree of risk. You should carefully consider the risks and uncertainties described below together with all of the other information in this Quarterly Report on Form 10-Q and our Annual Report on Form 10-K, before making a decision to invest in our common stock. The risks and uncertainties described below may not be the only ones we face. If any of the risks actually occur, our business, financial condition, operating results and prospects could be materially and adversely affected. In that event, the trading price of our common stock could decline, and you could lose part or all of your investment.

Risks Related to Our Business

The Merger, the pendency of the Merger or our failure to complete the Merger could have a material adverse effect on our business, results of operations, financial condition and stock price.

On October 26, 2017, we entered into an Agreement and Plan of Merger, or the Merger Agreement, with [Elliott Management Corporation]. Completion of the Merger is subject to the satisfaction of various conditions, including approval of the Merger by our shareholders, the absence of certain legal impediments, a minimum closing cash balance of at least $230 million, and the absence of a material adverse effect on our business. There is no assurance that all of the various conditions will be satisfied, or that the Merger will be completed on the proposed terms, within the expected timeframe, or at all. Furthermore, there are additional inherent risks in the Merger, including the risks detailed below.

Risks related to the pendency of the Merger

During the period prior to the closing of the Merger, our business is exposed to certain inherent risks due to the effect of the announcement or pendency of the Merger on our business relationships, financial condition, operating results and business, including:


•	potential uncertainty in the marketplace, which could lead current and prospective end-user customers to purchase from other vendors or delay purchasing from us;


•	the possibility of disruption to our business and operations, including diversion of management attention and resources, increased transaction costs, and the potentially negative impact on our relationships with our partners, third-party manufacturers and suppliers;


•	the inability to attract and retain key personnel, and the possibility that our current employees could be distracted, and their productivity decline as a result, due to uncertainty regarding the Merger;


•	the inability to pursue alternative business opportunities or make changes to our business pending the completion of the Merger, and other restrictions on our ability to conduct our business;


•	the fact that under the terms of the Merger Agreement, we are unable to solicit other acquisition proposals during the pendency of the Merger;


•	the amount of the costs, fees, expenses and charges related to the Merger Agreement and the Merger; and


•	other developments beyond our control, including, but not limited to, changes in domestic or global economic conditions that may affect the timing or success of the Merger.

Risks that the Merger may be delayed or may not be completed

The Merger may be delayed, and may ultimately not be completed, due to a number of factors, including:


•	the failure to obtain the approval of the Merger Agreement by our shareholders;


•	the failure to obtain regulatory approvals from various governmental entities (or the imposition of any conditions, limitations or restrictions on such approvals);


•	potential future shareholder litigation and other legal and regulatory proceedings, which could delay or prevent the Merger; and


•	the failure to satisfy the other conditions to the completion of the Merger, including the possibility that a material adverse effect on our business would permit Elliot not to close the Merger.

Risks to our business if the Merger does not close

If the Merger does not close, our business and shareholders would be exposed to additional risks, including:


•	to the extent that the current market price of our stock reflects an assumption that the Merger will be completed, the price of our common stock could decrease if the Merger is not completed;


•	investor confidence could decline, shareholder litigation could be brought against us, relationships with existing and prospective customers, suppliers and other business partners may be adversely impacted, we may be unable to retain key personnel, and profitability may be adversely impacted due to costs incurred in connection with the pending Merger; and


•	the requirement that we pay a termination fee of $47.2 million to Elliot if we terminate the agreement governing the Merger under certain circumstances.

Risks related to the successful completion of the Merger

Even if successfully completed, there are certain risks to our shareholders from the Merger, including:


•	the amount of cash to be paid under the Merger Agreement is fixed and will not be adjusted for changes in our business, assets, liabilities, prospects, outlook, financial condition or operating results or in the event of any change in the market price of, analyst estimates of, or projections relating to, our common stock; and


•	the fact that, if the Merger is completed, shareholders will forego the opportunity to realize the potential long-term value of the successful execution of our current strategy as an independent company.

The network traffic visibility market is rapidly evolving and difficult to predict. If the network traffic visibility market does not evolve as we anticipate or if our target end-user customers do not adopt our Visibility Platform or our Security Delivery Platform, our sales will not grow as quickly as anticipated and our stock price could decline.

We are in a new, rapidly evolving category within the network infrastructure industry that focuses on providing organizations with enhanced visibility and control over their networks through the efficient collection and analysis of network traffic. As such, it is difficult to predict important market trends, including how large the network traffic visibility market will be, or when and what products end-user customers will adopt. For example, organizations that currently use traditional approaches may believe that these approaches already provide them with sufficient visibility and control to secure and manage their network traffic. Therefore, they may continue spending their network infrastructure budgets on these products and may not adopt our Visibility Platform or Security Delivery Platform in addition to or in lieu of such products.

If the market for network traffic visibility does not evolve in the way we anticipate, if organizations do not recognize the benefits of our solution, if we are unable to sell our family of products to end-user customers, or if we are not able to effectively expand into new or adjacent markets, then our revenue may not grow as expected or may decline, and our stock price could decline.

New or existing technologies that are perceived to address network traffic visibility or address the need for network traffic visibility in different ways could gain wide adoption and supplant our products, thereby weakening our sales and our financial results.

The introduction of products and services embodying new technologies could render our existing products obsolete or less attractive to end-user customers. Other network traffic visibility technologies exist and could be developed in the future, and our business could be materially negatively affected if such technologies are widely adopted. We may not be able to successfully anticipate or adapt to changing technology or customer requirements on a timely basis, or

at all. If we fail to keep up with technological changes, do not effectively adapt our technology to next generation network infrastructure deployments or fail to convince our end-user customers and potential end-user customers of the value of our solution even in light of new technologies, our business, operating results and financial condition could be materially and adversely affected.

If we are unable to introduce new products successfully and to make enhancements to existing products, our growth rates would likely decline and our business, operating results and competitive position could suffer.

Our continued success depends on our ability to identify and develop new products and to enhance and improve our existing products, and the acceptance of those products by our existing and target end-user customers. Our growth would likely be adversely affected if:


•	we fail to correctly anticipate technology trends and introduce new products or product enhancements to address those trends;


•	our new products or product enhancements are not timely introduced or do not function as expected;


•	we fail to successfully manage the transition to new products from the products they are replacing;


•	we do not invest our development efforts in appropriate products or enhancements for markets in which we now compete and expect to compete;


•	we fail to predict the demand for new products following their introduction to market;


•	these new products or enhancements do not address existing or target end-user customer needs or do not attain broad market acceptance; or


•	lower cost products negatively impact sales of other existing products.

We invest substantial amounts of time and resources in researching and developing new products and enhancing existing products by incorporating additional features, improving functionality and adding other improvements to meet end-user customers’ rapidly evolving demands in our highly competitive industry. Our research and development expenses were $59.5 million, or 27% of our revenue in the nine months ended September 30, 2017, and $50.9 million, or 23% of revenue in the nine months ended October 1, 2016.

Our future plans contemplate significant investments in research and development and related product opportunities. In addition, we plan to increasingly use third-party joint development and original design manufacturing partners for the development of future products in our road map. We believe that we must continue to dedicate a significant amount of resources to our research and development efforts and increase our investment in joint development relationships to maintain our competitive position. We have limited experience in joint development of products and our increasing use of third-party joint development and original design manufacturers reduces our control over the design, as well as the timing and delivery, of products to the market. If we do not manage these joint design relationships successfully, future products may be delayed or the features and quality of the products may not meet our expectations or that of our customers. We have invested and continue to invest in our internal research and development capabilities and other internal research and development efforts as well as third-party design and manufacturing relationships without being certain that they will result in products that the market will accept or that will expand our share of those markets.

The introduction of new products or product enhancements may shorten the life cycle of our existing products, or replace sales of some of our current products, thereby offsetting the benefit of even a successful product introduction, and may cause end-user customers to defer purchasing our existing products in anticipation of the new products.

Failure to successfully introduce new products to our portfolio could harm our operating results by decreasing sales, increasing our inventory levels of older products and exposing us to greater risk of product obsolescence. We have also experienced, and may in the future experience, delays in developing and releasing new products and product enhancements. This has led to, and may in the future lead to, delayed sales, deferred revenue, increased expenses and lower than anticipated quarterly revenue. In addition, complexity and difficulties in managing product transitions at the end-of-life stage of a product can create excess inventory of components associated with the outgoing products that can lead to increased expenses. Any or all of the above problems could materially harm our business and operating results.

Our quarterly and annual operating results may vary significantly and be difficult to predict, which may cause our stock price to fluctuate.

Our quarterly and annual operating results have varied historically from period to period, and we expect that they will continue to fluctuate due to a variety of factors, many of which are outside of our control, including:


•	fluctuations in demand for our products and services, the timing of orders from our channel partners and end-user customers, and our ability to accurately forecast end-user customer demand;


•	the timing of our product shipments, which may depend on many factors such as inventory and logistics and our ability to ship new products on schedule and accurately forecast inventory requirements;


•	the budgeting cycles and internal purchasing priorities of our end-user customers;


•	seasonal buying patterns of our end-user customers;


•	changes in end-user customer or channel partner requirements or market needs;


•	dependence on key customers or large sales to individual customers;


•	the mix of products sold and the mix of revenue between products and services;


•	changes in the growth rate of the network traffic visibility market, the cyber-security market and related markets, such as the network infrastructure market, and the market for network management, analysis, compliance and security tools;


•	our ability to control costs, including operating expenses, the costs of hardware and software components, and other manufacturing costs;


•	our ability to timely develop, introduce and gain market acceptance for new products, technologies and services;


•	price competition;


•	any significant changes in the competitive environment, including the entry of new competitors, and any related discounting of products or services;


•	the timing and execution of product transitions or new product introductions, and related inventory costs;


•	deferral of orders from end-user customers in anticipation of new products or product enhancements announced by us or our competitors;


•	decisions by potential end-user customers to purchase alternative network traffic visibility solutions or cyber-security solutions from their existing network infrastructure and security vendors or other third parties;


•	our ability to establish and manage our distribution channels, and the effectiveness of any changes we make to our distribution model;


•	the ability of our suppliers and contract manufacturers to provide component parts and finished products in a timely manner;


•	changes in end-user customer renewal rates for our services and our ability to up-sell additional products;


•	general economic conditions, both domestically and in our foreign markets; and


•	future accounting pronouncements or standards changes or changes in our accounting policies and accounting standards including, but not limited to, changes in the revenue recognition standard scheduled to take place in 2018.

Any one of the factors above or the cumulative effect of some of the factors referred to above may result in significant fluctuations in our quarterly and annual operating results, including fluctuations in our key performance indicators. This variability and unpredictability could result in our failure to meet our internal operating plan or the expectations of securities analysts or investors for any period. In addition, a significant percentage of our operating expenses are fixed in nature in the short term and based on forecasted revenue trends. Accordingly, in the event of revenue shortfalls, we are generally unable to mitigate the negative impact on margins in the short term. For example, the market price of our shares fell substantially when we announced financial results for the fourth quarter of fiscal 2016 which included revenue results below our expectations and the expectations of securities analysts. If we fail to meet or exceed such expectations for these or any other reasons, the market price of our shares could fall substantially and we could face costly lawsuits, including securities class action suits.

Our revenue growth rate in recent periods can not be relied on as an indication of our future performance.

Our revenue growth rates have been highly variable in recent periods. We experienced annual revenue growth rates of 40% and 41% in fiscal 2016 and fiscal 2015, respectively, followed by revenue decline of 5% and 4% when comparing the three months ended September 30, 2017 to the three months ended October 1, 2016 and the nine months ended September 30, 2017 to the nine months ended October 1, 2016, respectively. Our revenue growth rates in future periods may be increasingly difficult to predict, especially as we enter new markets and expand our cloud-focused solutions. For example, we are seeing the public cloud cause a shift in deployment architectures across the industry. To the extent customers delay their purchasing decisions as they consider new deployment architectures or if they do not adopt our cloud-focused solutions at a rate sufficient to maintain our revenue growth, our operating results would be adversely impacted. You should not rely on our revenue for any prior quarterly or annual period as any indication of our future revenue or revenue growth. If we are unable to maintain consistent revenue or revenue growth, our business, financial condition, results of operations and prospects could be materially and adversely affected and our stock price could decline.

We compete in highly competitive markets, and competitive pressures from existing and new companies may adversely impact our business and operating results.

The markets in which we compete are highly competitive. We expect competition to intensify in the future as existing competitors bundle new and more competitive offerings with their existing products and services, and as new market entrants introduce new products into our markets. This competition could result in increased pricing pressure, reduced profit margins, increased sales and marketing expenses and our failure to increase, or the loss of, market share, any of which would likely seriously harm our business, operating results and financial condition. We also expect that competition will continue to increase as a result of advancements in networking technology and architecture. If we do not keep pace with product and technology advances and otherwise keep our product offerings competitive, there could be a material and adverse effect on our competitive position, revenue and prospects for growth.

We compete either directly or indirectly with certain large Ethernet switch vendors, such as Cisco Systems Inc., and Arista Networks, Inc., and network management, analysis, compliance and security tool vendors, including Ixia (which was recently acquired by Keysight Technologies, Inc.) and NetScout Systems, Inc., that offer solutions that address a portion of the issues that we solve. The principal competitive factors in our markets include functionality and performance, price and total cost of ownership, ease of use, flexibility and scalability of deployment, brand awareness, breadth of portfolio, product reliability and quality, interoperability with other products, the extent and speed of user adoption and quality of service, support and fulfillment.

Many of our current and potential competitors are substantially larger and have greater financial, technical, research and development, sales and marketing, manufacturing, distribution and other resources and greater name recognition. We could also face competition from new market entrants, including current technology partners. In addition, many of our existing and potential competitors enjoy substantial competitive advantages, such as:


•	longer operating histories;


•	the capacity to leverage their sales efforts and marketing expenditures across a broader portfolio of products;


•	broader distribution and established relationships with channel partners;


•	access to larger customer bases;


•	greater resources to make acquisitions;


•	larger intellectual property portfolios;


•	the ability to bundle competitive offerings with other products and services; and


•	greater customer support.

As a result, increased competition could result in fewer or delayed customer orders, price reductions, reduced operating margins and loss of market share. Our competitors also may be able to provide end-user customers with capabilities or benefits different from or greater than those we can provide in areas such as technical qualifications or geographic presence, or to provide end-user customers a broader range of products, services and prices. Some of our larger potential competitors have substantially broader product offerings and could leverage their relationships based on other products or incorporate functionality into existing products to gain business in a manner that discourages users from purchasing our products, including through selling at zero or negative margins, product bundling or closed technology platforms. These larger potential competitors may also have more extensive relationships within existing and potential end-user customers that provide them with an advantage in competing for business with those end-user

customers. In addition, to the extent that one of our competitors establishes or strengthens a cooperative relationship with, or acquires, one or more of the network management, analysis, compliance and security tool vendors that we have relationships with, it could adversely affect our ability to compete. Our ability to compete will depend upon our ability to provide a better solution than our competitors at a competitive price. To remain competitive, we may be required to make substantial additional investments in research, development, marketing and sales in order to respond to competition, and there is no assurance that these investments will achieve any returns for us or that we will be able to compete successfully in the future.

We also expect increased competition if our market continues to expand. Conditions in our market could change rapidly and significantly as a result of technological advancements or other factors. In addition, current or potential competitors may be acquired by third parties that have greater resources available. For example, our competitor, Ixia was recently acquired by Keysight Technologies. As a result of these acquisitions, our current or potential competitors, such as Ixia, might take advantage of the greater resources of the larger organization to compete more aggressively against us.

We depend on growth in markets relating to network security, management and analysis, and lack of growth or contraction in one or more of these markets could have a material adverse effect on our sales and financial condition.

Demand for our products is linked to, among other things, growth in the size and complexity of network infrastructures and the demand for networking technologies addressing the security, management and analysis of such infrastructures. If this demand declines or if we do not effectively adapt our technology to next generation network infrastructure deployments, our sales, profitability and financial condition would be materially adversely affected. Segments of the network infrastructure industry have in the past experienced significant economic downturns. The occurrence of any of these factors in the markets relating to network security, management and analysis could materially adversely affect our sales, profitability and financial condition. Furthermore, these markets are dynamic and evolving. Our future financial performance will depend in large part on continued growth in the number of organizations investing in their network infrastructure and the amount they commit to such investments. The market for network infrastructure may not continue to grow at historic rates, or at all. If this market fails to grow, or grows more slowly than we currently anticipate, our sales and profitability could be adversely affected.

If our end-user customers do not continue to purchase our products or expand deployment of our technologies, our ability to grow our business and improve our operating results and financial condition may be adversely affected.

A significant portion of our revenues come from new or recurring purchases of products from our installed base of end-user customers. Our future success depends, in part, on our ability to increase the adoption of our products within and across our existing end-user customers and future end-user customers. If we fail to expand existing deployments or sell additional products to our customers, our ability to grow our business and improve our operating results and financial condition would be adversely affected.

Our sales cycles can be long and unpredictable, and our sales efforts require considerable time and expense.

We have experienced difficulty managing lengthening and increasingly unpredictable sales cycles in the past. Our sales efforts involve educating our end-user customers about the use and benefits of our solutions, including their technical capabilities. End-user customers often undertake an evaluation and testing process that can result in a lengthy sales cycle. Also, as our distribution strategy typically leverages a channel model, utilizing distributors, the level of variability in the length of sales cycles across transactions has increased and made it more difficult to predict the timing of many of our sales transactions. We spend substantial time and resources on our sales efforts without any assurance that our efforts will produce any sales or a material amount of revenue from such sales. In addition, product purchases are frequently subject to budget constraints, multiple approvals and unplanned administrative, processing and other delays. These factors, among others, have in the past led to, and could continue to result in, long and unpredictable sales cycles.

We sell our products primarily to enterprise IT departments and service providers. Our sales cycles typically range from three to six months and are generally longer for larger transactions. Often times, our larger transactions are part of larger data center projects or upgrades by our customers and we have little ability to influence the timing of these transactions. As a result, our sales cycles can often be more than six months, with sales cycles involving service providers taking significantly longer to complete. To the extent that the mix of our future sales shifts to include relatively more revenue from service providers, the average length of our sales cycles will likely increase. Furthermore, our sales to federal, state and local governmental agency end-user customers have fluctuated in recent periods, and we have in recent periods and may in the future increase our sales efforts to governmental entities. Selling to governmental

entities can be highly competitive, expensive and time consuming, often requiring significant upfront time and expense without any assurance that some of these efforts will generate a sale. As a result of these lengthy and uncertain sales cycles and the increasing size of our transactions, it is difficult for us to predict when end-user customers may purchase solutions and accept products from us. If we are unable to effectively manage the sales cycle or if we fail to close a large transaction or multiple smaller transactions that we expect to close in a given period, our operating results may vary significantly from period to period and may be materially adversely affected.

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

We were founded in 2004 and sold our first products commercially in 2005. We have experienced rapid growth since our inception, and we have been increasing the breadth and scope of our product offerings. The majority of our revenue growth, however, has occurred over the past six years. This limited operating history, as well as the early stage of our relationships with many of our channel partners, makes financial forecasting and evaluation of our business difficult. Furthermore, because we depend in part on the market’s acceptance of our products, it is difficult to evaluate trends that may affect our business. We have encountered and will continue to encounter risks and difficulties frequently experienced by growing companies in rapidly changing industries. If we do not address these risks successfully, our business and operating results would be adversely affected, and our stock price could decline.

Some of the components and technologies used in our products are purchased and licensed from a single source or a limited number of sources. The loss of any of these suppliers might cause us to incur additional transition costs, result in delays in the manufacturing and delivery of our products, or cause us to carry excess or obsolete inventory and could require us to redesign our products.

Although supplies of our components are generally available from a variety of sources, we currently depend on a single source or a limited number of sources for some components included in our products. For example, processors that we use in our products are manufactured by Broadcom Corp., Freescale Semiconductor. Ltd., Intel Corporation and Cavium, Inc. and are currently available only from a limited number of sources, and neither we nor, to our knowledge our manufacturers have entered into supply agreements with such sources. As there are no other sources for identical components and technologies, if we lost any of these suppliers or were unable to acquire enough of these components or license these technologies on acceptable terms or at all, we would not be able to sell our products for a significant period of time, and we could incur significant costs to redesign our hardware and software to incorporate components or technologies from alternative sources or to qualify alternative suppliers. Our reliance on a single source or a limited number of suppliers involves a number of additional risks, including risks related to:


•	supplier capacity constraints;


•	price increases;


•	timely delivery;


•	component quality;


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


•	delays in, or the inability to execute on, a supplier roadmap for components and technologies; and


•	natural disasters.

In addition, for certain components for which there are multiple sources, we are subject to potential price increases and limited availability as a result of market demand for these components. In the past, unexpected demand for computer and network products has caused worldwide shortages of certain electronic parts. If similar shortages occur in the future, our business would be adversely affected. Although we carry some finished goods inventory of our products, we and our manufacturers rely on our suppliers to deliver necessary components in a timely manner. We and our manufacturers rely on purchase orders rather than long-term contracts with these suppliers. As a result, we or our manufacturers might not be able to secure sufficient components, even if they were available, at reasonable prices or of acceptable quality to build products in a timely manner and, therefore, might not be able to meet end-user customer demands for our products, which would have a material and adverse effect on our business, operating results and financial condition.

We rely on third-party channel partners for a substantial portion of our revenue. If our partners fail to perform, our ability to sell our products and services would be limited. Further, if we fail to optimize our channel partner model going forward, our operating results would be harmed.

Our revenue is primarily generated through sales by our channel partners, which include distributors and resellers. We depend upon our channel partners to assist with the sales process through introduction to accounts and the

distribution of our products. In North America we principally rely on two distributors, Global Convergence Inc., or GCI, and Arrow Enterprise Computing Solutions, Inc. or Arrow. GCI accounted for less than 10% and 16% of our revenue for the three and nine months ended September 30, 2017, respectively and 33% of our revenue for the fiscal year 2016. Arrow accounted for 36% and 29% of our revenue for the three and nine months ended September 30, 2017, respectively and 26% of our revenue for the fiscal year 2016. To the extent our channel partners are unable to generate an increasing amount of our sales opportunities, are unsuccessful in selling our products, or we are unable to enter into arrangements with, and retain, a sufficient number of high quality channel partners in each of the regions in which we sell products, and keep them motivated to sell our products, our ability to sell our products and operating results would be harmed. Furthermore, any adverse change in the financial or business condition of our third-party channel partners could disrupt our ability to fulfill orders to our end-user customers, damage our relationships with our end-user customers or adversely impact our financial condition and results of operations. The termination of our relationship with any significant channel partner may adversely impact our sales, operating results and revenue growth. If we fail to optimize our channel partner model or fail to manage existing sales channels, our business and operating results could be materially and adversely affected.

Managing inventory of our products and product components is complex. Insufficient inventory may result in lost sales opportunities or delayed revenue, while excess inventory may harm our gross margins.

Managing inventory of our products and product components is complex with many critical components requiring long lead times from the component manufacturer. These long lead times place added importance on our ability to effectively forecast end-user customer demand so that we have the right amount of product or product components available. Managing inventory is further complicated as our channel partners may increase orders during periods of product shortages, cancel orders, return product or take advantage of price protection (if any) or delay orders in anticipation of new products. They also may adjust their orders in response to the supply of our products and the products of our competitors that are available to them and in response to seasonal fluctuations in end-user customer demand. Furthermore, if the time required to manufacture certain products or ship products increases for any reason, this could result in inventory shortfalls. Managing our inventory depends significantly on our ability to accurately forecast end-user customer demand for our products. Our inventory management and demand planning systems and related supply chain visibility tools may be inadequate to enable us to effectively manage inventory. Inventory management remains an area of focus as we balance the need to maintain inventory levels that are sufficient to ensure competitive lead times against the risk of inventory obsolescence because of rapidly changing technology and customer requirements. If we ultimately determine that we have excess inventory, we may have to reduce our prices or write-down inventory, which in turn could result in lower gross margins. Alternatively, insufficient inventory levels may lead to shortages that result in delayed revenue or loss of sales opportunities altogether as potential end-user customers turn to competitors’ products that are readily available. If we are unable to effectively manage our inventory, our operating results could be adversely affected.

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

We outsource the manufacturing, systems assembly, testing and order fulfillment of our hardware products to third-party contract manufacturers, original design manufacturers and third party logistics providers. Jabil Circuit, Inc., or Jabil and Delta Networks, Inc., or DNI, manufacture and, through joint design arrangements with us, develop substantially all of our hardware products. We also contract with Expeditors International to provide warehousing, packaging, order fulfillment and light manufacturing services for our products. We rely on Jabil and, to a lesser extent, DNI to manufacture a substantial majority of our products.

Our reliance on these third parties reduces our control over the assembly and order fulfillment process, exposing us to risks, including reduced control over quality assurance, production costs and product supply. If we fail to effectively manage our relationship with our contract manufacturers, or if they experience delays, disruptions, capacity constraints or quality control problems in their operations, our ability to ship products to our end-user customers could be impaired and our competitive position and reputation could be harmed. Furthermore, Jabil manufactures our products in their facility in Guadalajara, Mexico. As such, these manufacturing operations may be subject to changes in the economic, security and political conditions in Mexico, or to changes in Mexico's trade relations with the United States, which might interrupt or impact manufacturing operations. For example, the political climate in the United States has created some uncertainty whether the United States might impose tariffs or other restrictions on foreign imports, including imports from Mexico. If any such tariffs are imposed on products or components that we import, including those manufactured by Jabil, our costs could increase or our gross margins could be negatively impacted. Furthermore, any adverse change in the financial or business condition of our third-party contract manufacturers could disrupt our ability to supply quality products to our end-user customers. If we are required to change our contract manufacturers and cannot find a suitable alternative in a timely manner, we may lose revenue, incur increased costs and damage our relationships with our

channel partners and end-user customers. In addition, qualifying a new contract manufacturer and commencing production can be an expensive and lengthy process. If we experience increased demand that our contract manufacturers are unable to fulfill, or if they are unable to provide us with an adequate supply of high-quality products for any reason, we could experience a delay in our order fulfillment, and our business, operating results and financial condition would be adversely affected.

Defects, errors or vulnerabilities in our products, or the failure of our solution to improve network security, could harm our reputation and business.

Our products are complex and have contained and may contain undetected defects or errors, especially when first introduced or when new versions are released. Defects in our products may impede or block network traffic or cause our products to fail to provide network traffic visibility as intended. Further, defects in our products may impair the functionality or performance of the appliances and applications that rely on the data provided by our products. Defects in our products may lead to product returns and require us to implement design changes or software updates. Additionally, defects or vulnerabilities in our products or services may cause the networks of our end-user customers to be vulnerable to security attacks, cause them to fail to help secure networks, or temporarily interrupt the networking traffic of our end-user customers. Because the techniques used by computer hackers to access or sabotage networks change frequently and generally are not recognized until launched against a target, we may be unable to anticipate these techniques and provide a solution in time to fix the defect or vulnerability in our products or services. Furthermore, as we increasingly design and market our products with specific security-related features, our networks, products, and services could be targeted by attacks specifically designed to disrupt our business and harm our reputation. Any successful security attack on our network or on the network of one of our end-user customers that could be traced to a defect or vulnerability in one of our products or services could lead to significant liability or reputational harm that could have a material adverse impact on our operating results.

Any defects or errors in our products, or the perception of such defects or errors, could result in:


•	expenditure of significant financial and product development resources in efforts to analyze, correct, eliminate or work around errors or defects;


•	loss of existing or potential end-user customers or channel partners;


•	delayed or lost revenue;


•	delay or failure to attain market acceptance;


•	delay in the development or release of new products or services;


•	negative publicity, which will harm our reputation;


•	warranty claims against us, which could result in an increase in our provision for warranty reserve;


•	an increase in collection cycles for accounts receivable or the expense and risk of litigation; and


•	harm to our operating results.

Although we have limitation of liability provisions in our standard terms and conditions, they may not fully or effectively protect us from claims as a result of federal, state or local laws or ordinances or unfavorable judicial decisions in the United States or other countries. The sale and support of our products also entail the risk of product liability claims. We maintain insurance to protect against certain claims associated with the use of our products, but our insurance coverage may not adequately cover any claim asserted against us. In addition, even claims that ultimately are unsuccessful could result in our expenditure of funds in litigation and divert management’s time and other resources.

We rely on the availability of licenses to third-party software and other intellectual property.

Many of our products and services include software or other intellectual property licensed from third parties, and we otherwise use software and other intellectual property licensed from third parties in our business. This exposes us to risks over which we may have little or no control. For example, a licensor may have difficulties keeping up with technological changes or may stop supporting the software or other intellectual property that it licenses to us. Also, it will be necessary in the future to renew certain licenses, expand the scope of certain existing licenses or seek new licenses, relating to various aspects of these products and services, or otherwise relating to our business, which may result in increased license fees. There can be no assurance that the necessary licenses will be available on acceptable terms, if at all. In addition, a third-party may assert that we or our end-user customers, are in breach of the terms of a license, which could, among other things, give such third-party the right to terminate a license, seek damages from us, or both. The inability to obtain or maintain certain licenses or other rights or to obtain or maintain such licenses or rights on favorable terms, or the need to engage in litigation regarding these matters, could result in delays in releases

of products and services, and could otherwise disrupt our business, until equivalent technology can be identified, licensed, developed and integrated (if at all). Any of these events could have a material adverse effect on our business, operating results and financial condition. Moreover, the inclusion in our products and services of software or other intellectual property licensed from third parties on a non-exclusive basis may limit our ability to differentiate our products from those of our competitors.

Furthermore, we have a license and services agreement with Tall Maple Systems, Inc., or Tall Maple, pursuant to which we have been granted a perpetual, non-exclusive, worldwide license to certain software code of Tall Maple, which we integrate into the software components of our H Series products and certain additional products and which can be integrated into our other products and applications. In return, we paid Tall Maple a license fee. The agreement can only be terminated for cause upon written notice of a material breach and if the other party does not cure such breach within 30 days of such notice. We were notified in 2013 that the assets of Tall Maple were acquired by a third party. If our agreement with Tall Maple is terminated as a result of a material breach by us that we do not timely cure, we may need to identify, license or develop equivalent software, and integrate such replacement software into the software component of our H Series products, which could impede our ability to sell our H Series products until equivalent software is identified, licensed or developed, and integrated. These delays, if they occur, could adversely affect our business, operating results and financial condition.

Failure to protect our proprietary technology and intellectual property rights could substantially harm our business and operating results.

The success of our business depends on our ability to protect and enforce our trade secrets, trademarks, copyrights, patents and other intellectual property rights. We attempt to protect our intellectual property under patent, trademark, copyright and trade secret laws, and through a combination of confidentiality procedures, contractual provisions and other methods, all of which offer only limited protection.

As of September 30, 2017, we had 44 issued patents in the United States, but this number may be relatively small in comparison to some of our competitors and potential competitors. Additionally, as of September 30, 2017, we had 37 pending U.S. patent applications. Internationally, as of September 30, 2017, we had 10 issued patents and a number of pending patent applications. We may file additional patent applications in the future. The process of obtaining patent protection is expensive and time-consuming, and we may not be able to prosecute all necessary or desirable patent applications at a reasonable cost or in a timely manner. We may choose not to seek patent protection for certain innovations and may choose not to pursue patent protection in certain jurisdictions. Furthermore, it is possible that our patent applications may not issue as granted patents, that the scope of our issued patents will be insufficient or not have the coverage originally sought, that our issued patents will not provide us with any competitive advantages, and that our patents and other intellectual property rights may be challenged by others or invalidated through administrative process or litigation. In addition, issuance of a patent does not guarantee that we have an absolute right to practice the patented invention, or that we have the right to exclude others from practicing the claimed invention. As a result, we may not be able to obtain adequate patent protection or to enforce our issued patents effectively.

In addition to patented technology, we rely on our unpatented proprietary technology and trade secrets. Despite our efforts to protect our proprietary technology and trade secrets, unauthorized parties may attempt to misappropriate, reverse engineer or otherwise obtain and use them. The contractual provisions that we enter into with employees, consultants, partners, vendors and customers may not prevent unauthorized use or disclosure of our proprietary technology or intellectual property rights and may not provide an adequate remedy in the event of unauthorized use or disclosure of our proprietary technology or intellectual property rights. Moreover, policing unauthorized use of our technologies, products and intellectual property is difficult, expensive and time-consuming, particularly in foreign countries where the laws may not be as protective of intellectual property rights as those in the United States and where mechanisms for enforcement of intellectual property rights may be weak. For example, the laws of India, where we have established a research and development facility, do not protect our proprietary rights to the same extent as the laws of the United States. We may be unable to determine the extent of any unauthorized use or infringement of our products, technologies or intellectual property rights.

From time to time, we may need to take legal action to enforce our patents and other intellectual property rights, to protect our trade secrets, to determine the validity and scope of the intellectual property rights of others or to defend against claims of infringement, misappropriation or invalidity. Such litigation could result in substantial costs and diversion of resources and could negatively affect our business, operating results, financial condition and cash flows. If we are unable to adequately protect our intellectual property rights, we may find ourselves at a competitive disadvantage to others who need not incur the additional expense, time and effort required to create the innovative products that have enabled us to be successful to date.

Assertions by third parties of infringement or other violations by us of their intellectual property rights, or other lawsuits asserted against us, could result in significant costs and substantially harm our business and operating results.

Patent and other intellectual property disputes are common in the network infrastructure industry. Some companies in the network infrastructure industry, including some of our competitors, own large numbers of patents, copyrights, trademarks and trade secrets, which they may use to assert claims against us. Third parties may in the future assert claims of infringement, misappropriation or other violations of intellectual property rights against us. They may also assert such claims against our end-user customers or against channel partners whom we indemnify against claims that our products violate the intellectual property rights of third parties. As the number of products and competitors in our market increase and overlaps occur, claims of infringement, misappropriation and other violations of intellectual property rights may increase. Any claim of infringement, misappropriation or other violation of intellectual property rights by a third party, even those without merit, could cause us to incur substantial costs defending against the claim and could distract our management from our business.

The patent portfolios of our most significant competitors and potential competitors may be larger than ours. Any disparity between our patent portfolio and the patent portfolios of our most significant competitors or potential competitors may increase the risk that they may sue us for patent infringement and may limit our ability to counterclaim for patent infringement or settle through patent cross-licenses. In addition, future assertions of patent rights by third parties, and any resulting litigation, may involve patent holding companies or other adverse patent owners who have no relevant product revenue and against whom our own patents may therefore provide little or no deterrence or protection. We cannot assure you that we are not infringing or otherwise violating any third-party intellectual property rights.

An adverse outcome of a dispute may require us to, among other things; pay substantial damages, including treble damages, if we are found to have willfully infringed a third party’s patents or copyrights; cease making, licensing or using solutions that are alleged to infringe or misappropriate the intellectual property of others; expend additional development resources to attempt to redesign our products or services or otherwise to develop non-infringing technology, which may not be successful; enter into potentially unfavorable royalty or license agreements in order to obtain the right to use necessary technologies or intellectual property rights; and indemnify our partners and other third parties. Any damages or royalty obligations we may become subject to, and any third-party indemnity we may need to provide, as a result of an adverse outcome could harm our operating results. Royalty or licensing agreements, if required or desirable, may be unavailable on terms acceptable to us, or at all, and may require significant royalty payments and other expenditures. In addition, some licenses may be non-exclusive, and therefore our competitors may have access to the same technology licensed to us. Any of these events could seriously harm our business, financial condition and operating results.

Under the indemnification provisions of our standard channel contracts and certain additional sales contracts, we agree to defend against third-party claims asserting infringement of certain intellectual property rights, which typically include patents, copyrights and trademarks, and to pay judgments entered on, and certain damages and costs in connection with, such claims. Our exposure under the channel indemnification provisions is generally limited to the total amount paid under the agreement (i) for the 12 months preceding the claim or (ii) for the products at issue. However, certain agreements include indemnification provisions that could potentially expose us to losses in excess of the amount received under the agreement. We have not incurred any material costs in the past as a result of such indemnification obligations, and have not accrued any liabilities related to such obligations in our consolidated financial statements.

In addition, we may, from time to time, be a party to other lawsuits in the normal course of our business. Litigation in general, and intellectual property and securities litigation in particular, can be expensive, lengthy and disruptive to normal business operations. Moreover, the results of complex legal proceedings are difficult to predict. Responding to lawsuits is likely to be expensive and time consuming for us, and could divert our management’s attention from our business. An unfavorable resolution of any lawsuit could adversely affect our business, operating results or 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, and although we monitor our use of open source software to avoid subjecting our products to conditions we do not intend, the terms of many open source licenses have not been interpreted by U.S. courts. As a result, there is a risk that these licenses could be construed in a way that could impose unanticipated conditions or restrictions on our ability to commercialize our products. In such an event, or if we fail to adequately monitor our use of open source software, we could be required to seek licenses from third parties to continue offering

our products, to make our proprietary code generally available in source code form, to re-engineer our products or to discontinue the sale of our products if re-engineering could not be accomplished on a timely basis, any of which could adversely affect our business, operating results and financial condition.

We are dependent on a single product family comprised of a limited number of products.

Our product offering is limited to a single product family comprised of our GigaVUE, GigaSECURE, GigaSMART, Gigamon Visibility Platform for Amazon Web Services (AWS) and G-TAP products. Historically, we have derived a substantial portion of our revenue from sales of our GigaVUE appliances and related services, and we expect to continue to derive a significant portion of our revenue from sales of our GigaVUE appliances and related services for the foreseeable future. A decline in the price of these products and related services, whether due to competition or otherwise, or our inability to increase sales of these products, would harm our business and operating results more seriously than it would if we derived significant revenue from a variety of product lines and services. We expect that this concentration of revenue from a single product family comprised of a limited number of products will continue for the foreseeable future. As a result, our future growth and financial performance will depend heavily on our ability to develop and sell enhanced versions of our GigaVUE appliances and the related family of products and services. If we fail to deliver product enhancements, new releases or new products that end-user customers want, it will be more difficult for us to succeed.

Adverse economic conditions or reduced information technology and network or security infrastructure spending may adversely impact our business and operating results.

Our business depends on the overall demand for information technology, network or security infrastructure and the market for network security analysis, compliance and monitoring tools. In addition, the purchase of our products and services is often discretionary and may involve a significant commitment of capital and other resources. Weak global economic conditions, or a reduction in information technology and network infrastructure spending even if economic conditions improve, could adversely impact our business, financial condition and operating results in a number of ways, including longer sales cycles, lower prices for our products and services, higher default rates among our distributors, reduced unit sales and lower or no growth. As global or regional economic conditions continue to be volatile or economic uncertainty remains, trends in information technology and network infrastructure spending also remain unpredictable and subject to reductions due to credit constraints and uncertainties about the future. Unfavorable economic conditions may lead end-user customers to delay or reduce purchases of our solution. Demand for our solution may not reach our sales targets, or may decline, when there is an economic downturn or economic uncertainty. Our sensitivity to economic cycles and any related fluctuation in demand may have a material adverse effect on our business, financial condition and operating results.

The market for cloud-based and cloud-focused solutions has been accelerating. If the market does not continue to develop or develops more slowly than we expect, or our cloud-focused solutions are not adopted or adopted more slowly than we anticipate, our business could be harmed.

We recently introduced our first Visibility Platform offering addressing the public cloud (Gigamon Visibility Platform for AWS) and expect to expand the range of our cloud-focused offerings in the future. Many factors may affect the market acceptance of cloud-based and cloud-focused solutions, including:

•perceived security capabilities and reliability;

•perceived concerns about the ability to scale operations for large enterprise customers;

•concerns with entrusting a third party to store and manage critical data; and

•the level of configurability or customizability of the solution.

If this market does not continue to accelerate as we anticipate, if organizations that establish a presence in the cloud do not perceive the benefits of our cloud-focused solutions, or if our competitors or new market entrants are able to develop cloud-focused solutions that are or are perceived to be more effective than ours, this portion of our business may not grow further or may develop more slowly than we expect, either of which would adversely affect our business and operating results.

The average selling price of our products has decreased from time to time, and may decrease in the future, which may negatively impact gross profits.

From time to time, the average selling price of our products has decreased. In the future, it is possible that the average selling prices of our products will decrease in response to competitive pricing pressures, increased sales discounts, new product introductions by us or our competitors or other factors. Such pricing pressures may also be dependent upon the mix of products sold, the mix of revenue between products and services and the degree to which

products and services are bundled and sold together for a package price. Therefore, in order to maintain our profitability, we must develop and introduce new products and product enhancements on a timely basis and continually reduce our product costs. Our failure to do so would likely cause our revenue and gross profits to decline, which would harm our business and operating results. In addition, we may experience substantial period-to-period fluctuations in future operating results in the event we experience an erosion of our average selling prices.

We rely on revenue from support services which may decline, and because we recognize revenue from support services over the term of the relevant service period, downturns or upturns in sales of support services are not immediately reflected in full in our operating results.

Our service revenue has become a more meaningful part of revenue in recent periods. Starting in the quarter ended September 26, 2015, we began to sell first year maintenance and support as an additional offering. Prior to that time, the first year of maintenance and support was bundled as part of the initial contract to purchase our products. Sales of new or renewal services contracts may decline and fluctuate as a result of a number of factors, including end-user customers’ level of satisfaction with our products and services, the prices of our products and services, the prices of products and services offered by our competitors or reductions in our end-user customers’ spending levels. If our sales of new or renewal services contracts decline, our revenue and revenue growth may decline and our business will suffer. In addition, we recognize service revenue over the term of the relevant service period, which is typically 12 months. As a result, some of the revenue we report each quarter is the recognition of deferred revenue from services contracts entered into during previous quarters. Consequently, a decline in new or renewed service contracts in any one quarter will not be fully reflected in revenue in that quarter but will negatively affect our revenue in future quarters. Accordingly, the effect of significant downturns in new or renewed sales of our services is not reflected in full in our operating results until future periods. Our service revenue also makes it difficult for us to rapidly increase our revenue through additional service sales in any period, as revenue from new and renewal service contracts must be recognized over the applicable service period. Furthermore, increases in the average term of services contracts would result in revenue for services contracts being recognized over longer periods of time.

Seasonality may cause fluctuations in our revenue and operating results.

We have experienced seasonality in our product revenue and operating results in the past, and we believe that we will continue to experience such seasonality in the future. The first quarter of each year is usually our lowest revenue quarter during the year and product revenue typically declines sequentially from the prior fourth quarter. We believe that this results in part from the procurement, budgeting and deployment cycles of many of our end-user customers. We generally expect a relative increase in sales in the second half of each year as budgets of our end-user customers for annual capital purchases are being fully utilized. We expect that seasonality will continue to affect our revenue and operating results in the future.

Our business and operations have experienced rapid growth, and if we do not appropriately manage any future growth, or are unable to improve our systems and processes, our operating results will be negatively affected.

We have experienced rapid growth over the last several years, which has placed a strain on our management, administrative, operational and financial infrastructure. In addition, some of the members of our current management team have only been working together for a short period of time. We also anticipate that additional investments in key channel partnerships and direct-sales personnel, as well as infrastructure, sales and marketing and research and development spending, will be required to:


•	scale our operations and increase productivity;


•	address the needs of our end-user customers;


•	further develop and enhance our products and services;


•	develop new technology; and


•	expand our markets and opportunity under management, including into new industry verticals and geographic areas.

Our success will depend in part upon our ability to manage our growth effectively. To do so, we must continue to increase the productivity of our existing employees and to hire, train and manage new employees as needed. To manage domestic and international growth of our operations and personnel, we will need to continue to improve our operational, financial and management controls and our reporting processes and procedures, and implement more extensive and integrated financial and business information systems. These additional investments will increase our operating costs, which will make it more difficult for us to offset any future revenue shortfalls by reducing expenses in

the short term. Moreover, if we fail to scale our operations successfully, our business and operating results could be materially and adversely affected.

If we are unable to implement and maintain effective internal control over financial reporting, the accuracy and timeliness of our financial reporting may be adversely affected.

We must maintain effective internal control over financial reporting in order to accurately and timely report our results of operations and financial condition. In addition, the Sarbanes-Oxley Act requires, among other things, that we assess the effectiveness of our internal control over financial reporting and the effectiveness of our disclosure controls and procedures quarterly. If we are not able to comply with the requirements of the Sarbanes-Oxley Act in a timely manner, 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 diminish investor confidence in our financial reporting and require additional financial and management resources, each of which may adversely affect our business and operating results.

We have reported material weaknesses in our financial reporting in the past. Although prior material weaknesses have been remediated, including certain material weaknesses which our management determined were remediated in connection with their review of our internal control over financial reporting for fiscal 2015, there can be no assurance that control deficiencies or other significant deficiencies or material weaknesses in our financial reporting will not occur in the future. Any failure to maintain or implement required new or improved controls, or difficulties we encounter in their implementation, could result in significant deficiencies or material weaknesses, or cause us to fail to meet our future reporting obligations. Internal control deficiencies could also result in a restatement of our financial statements in the future or cause investors to lose confidence in our reported financial information, which could cause a decline in the market price of our common stock.

We are dependent on the continued services and performance of our senior management and other key employees, the loss of any of whom could adversely affect our business, operating results and financial condition.

Our future performance depends on the continued services and contributions of our senior management and other key employees to execute on our business plan and to identify and pursue new opportunities and product innovations. The loss of services of senior management or other key employees could significantly delay or prevent the achievement of our development and strategic objectives. In addition, certain members of our current management team have recently joined us, including our Senior Vice President of Worldwide Sales, Burney Barker and our Chief Marketing Officer, Kim DeCarlis. The loss of the services of our senior management or other key employees for any reason could adversely affect our business, financial condition and operating results.

If we are unable to hire, retain and motivate qualified personnel, our business will suffer.

Our future success depends, in part, on our ability to continue to attract and retain highly skilled personnel. The loss of the services of any of our key personnel, the inability to attract or retain qualified personnel or delays in hiring required personnel, particularly in engineering and sales, may seriously harm our business, financial condition and operating results. None of our key employees has an employment agreement for a specific term, and any of our employees may terminate their employment at any time. Our ability to continue to attract and retain highly-skilled personnel will be critical to our future success. Competition for highly skilled personnel is frequently intense, especially in the San Francisco Bay Area, the location in which we have a substantial presence and need for highly-skilled personnel. We intend to continue to issue restricted stock units (and, to a lesser extent, stock options) as a key component of our overall compensation and employee attraction and retention efforts. In addition, we are required under GAAP to recognize compensation expense in our operating results for employee stock-based compensation under our equity grant programs, which may negatively impact our operating results and may increase the pressure to limit stock-based compensation. We may not be successful in attracting, assimilating or retaining qualified personnel to fulfill our current or future needs. Also, to the extent we hire personnel from competitors, we may be subject to allegations that they have been improperly solicited or divulged proprietary or other confidential information.

Our business could be negatively affected as a result of actions of activist shareholders

Responding to actions by activist shareholders can be costly and time-consuming, disrupting our operations, and diverting the attention of management and our employees. The perceived uncertainties as to our future direction may result in the loss of potential business opportunities, and may make it more difficult to attract and retain qualified personnel and business partners.

Our long-term success depends, in part, on our ability to further expand the sales of our products to end-user customers located outside of the United States, and therefore our business will be susceptible to risks associated with international operations.

While we currently maintain limited operations outside of the United States, we intend to expand these operations in the future. For example, in 2017 we expanded our operations in, and relocated a significant portion of our research and development facility to India and in 2016 completed the transition of our primary manufacturing operations, through Jabil, to Mexico. We have limited experience operating in foreign jurisdictions. Our inexperience in operating our business outside of the United States increases the risk that any international expansion efforts we may undertake will 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 overall business, operating results and financial condition.

A portion of our revenue is generated by sales to government entities, which are subject to a number of challenges and risks.

Sales to U.S. and foreign, federal, state and local governmental agency end-user customers have accounted for a significant amount of our revenue in recent periods, and we may in the future increase sales to government entities. Sales to government entities are subject to a number of risks. Selling to government entities can be highly competitive, expensive, and time-consuming, often requiring significant upfront time and expenses without any assurance that these efforts will generate a sale. Government certification requirements for products like ours may change, thereby restricting our ability to sell into the government sector until we have attained the revised certification. Government demand and payment for our products and services may be impacted by public sector budgetary cycles and funding authorizations, with funding reductions or delays adversely affecting public sector demand for our products and services. Our sales to date to government entities have been made indirectly through our channel partners. Government entities may have statutory, contractual or other legal rights to terminate contracts with our distributors and resellers for convenience or due to a default, and any such termination may adversely impact our operating results. We have contractual obligations to provide certain channel partners that sell to the government with certain pricing information that they may pass on to government entities. Governments routinely investigate and audit government contractors’ administrative processes and compliance, and any unfavorable audit could result in the government refusing to continue buying our products and services, a reduction of revenue, or fines or civil or criminal liability if the audit uncovers improper or illegal activities, which could adversely impact our operating results in a material way. Finally, for purchases by the U.S. government, the government may require that certain products to be manufactured in the United States and other relatively high cost manufacturing locations, and we may not manufacture all products in locations that meet such requirements, affecting our ability to sell these products to the U.S. government.

Our use of and reliance on research and development resources in India may expose us to unanticipated costs or events.

We opened a research and development center in India during the second quarter of fiscal 2015, expanded and relocated a significant portion of our research and development operations there in 2016, and, in the future, expect to increase our headcount and development activity at this facility. There is no assurance that our reliance upon research and development resources in India will enable us to achieve our research and development goals or greater resource efficiency. Further, our research and development efforts in India involve significant risks, including:


•	difficulty hiring and retaining appropriate engineering personnel due to intense competition for such resources and resulting wage inflation;


•	the knowledge transfer related to our technology and resulting exposure to misappropriation of intellectual property or information that is proprietary to us, our customers or other third parties;


•	heightened exposure to change in the economic, security and political conditions in India;


•	fluctuations in currency exchange rates and regulatory compliance in India; and


•	interruptions to our operations in India as a result of floods and other natural catastrophic events as well as man-made problems such as power disruptions or terrorism.

Difficulties resulting from the factors above and other risks related to our research and development activities in India could increase our research and development expenses, delay the introduction of new products, or impact our product quality, the occurrence of which could adversely affect our business and operating results.

We are dependent on various IT systems, and failures of or interruptions to those systems could harm our business.

Many of our business processes depend upon our IT systems, the systems and processes of third parties and on interfaces with the systems of third parties. For example, we rely on Microsoft AX Dynamics for our ERP system and Salesforce.com for our customer relationship management system. If those systems fail or are interrupted, or if our ability to connect to or interact with one or more networks is interrupted, our processes may function at a diminished level or not at all. This would harm our ability to ship products, and our financial results would likely be harmed.

In addition, reconfiguring our IT systems or other business processes in response to changing business needs may be time consuming and costly. To the extent this impacts our ability to react in a timely manner to specific market or business opportunities, our financial results would likely be harmed.

Failure to comply with 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. For example, our products are subject to various U.S. and foreign governmental regulations limiting the electromagnetic interference that our products can safely emit. If our products do not meet these regulatory standards, we may be required to stop shipping or recall non-compliant products until we are able to meet the applicable standards. Noncompliance with applicable regulations or requirements could subject us to investigations, sanctions, mandatory product recalls, enforcement actions, disgorgement of profits, fines, damages, 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.

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

The U.S. and various foreign governments have imposed controls, license requirements and restrictions on the import or export of some technologies, especially encryption technology, that apply to our products. 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.

Due to the global nature of our business, we could be adversely affected by violations of the U.S. Foreign Corrupt Practices Act, the U.K. Bribery Act, similar anti-bribery laws in other jurisdictions in which we operate, or various international trade or export laws.

The global nature of our business creates various domestic and local regulatory challenges. The U.S. Foreign Corrupt Practices Act, or the FCPA, the U.K. Bribery Act 2010, or the U.K. Bribery Act, and similar anti-bribery laws in other jurisdictions generally prohibit U.S.-based companies and their intermediaries from making improper payments to non-U.S. officials for the purpose of obtaining or retaining business. In addition, U.S.-based companies are required to maintain records that accurately and fairly represent their transactions and have an adequate system of internal accounting controls. We operate in areas of the world that experience corruption by government officials to some degree and, in certain circumstances, compliance with anti-bribery laws may conflict with local customs and practices. Our global operations require us to import and export to and from several countries, which geographically stretches

our compliance obligations. In addition, changes in such laws could result in increased regulatory requirements and compliance costs which could adversely affect our business, financial condition and results of operations. We cannot assure you that our employees or other agents will not engage in prohibited conduct and render us responsible under the FCPA, the U.K. Bribery Act or other anti-bribery laws. If we are found to be in violation of the FCPA, the U.K. Bribery Act or other anti-bribery laws (either due to acts or inadvertence of our employees, or due to the acts or inadvertence of others), we could suffer criminal or civil penalties or other sanctions, which could have a material adverse effect on our business.

We may expand through acquisitions of, or investments in, other companies, each of which may divert our management’s attention. Such efforts may result 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 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, including government regulatory approvals, which are beyond our control. Consequently, we can make no assurance that these transactions, once undertaken and announced, will close.

An acquisition or investment 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. An acquisition could also result in dilutive issuances of our equity securities, the incurrence of debt, contingent liabilities, amortization expenses or the write-off of goodwill. These challenges related to acquisitions or investments could adversely affect our business, operating results and financial condition.

If our estimates or judgments relating to our critical accounting policies are based on assumptions that change or prove to be incorrect, our operating results could fall below the expectations of securities analysts and investors, resulting in a decline in our stock price.

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, as provided in the section titled “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” the results of which form the basis for making judgments about the carrying values of assets, liabilities and equity, and the amount of revenue and expenses that are not readily apparent from other sources. Our operating results may be adversely affected if our assumptions change or if actual circumstances differ from those in our assumptions, which could cause our operating results to fall below the expectations of securities analysts and investors, resulting in a decline in our stock price. Significant assumptions and estimates used in preparing our consolidated financial statements include, or may in the future include, those related to revenue recognition, stock-based compensation expense, long-lived assets, excess and obsolete inventory write-downs, warranty reserves and accounting for income taxes including deferred tax assets and liabilities.

The nature of our business requires the application of complex revenue and expense recognition rules and the current legislative and regulatory environment affecting generally accepted accounting principles is uncertain. Significant changes in current principles could affect our financial statements going forward and changes in financial accounting standards or practices may cause adverse, unexpected financial reporting fluctuations and harm our operating results.

The accounting rules and regulations that we must comply with are complex and subject to interpretation by the FASB, the SEC and various bodies formed to promulgate and interpret appropriate accounting principles. Recent actions and public comments from the FASB and the SEC have focused on the integrity of financial reporting and internal controls. In addition, many companies’ accounting policies are being subject to heightened scrutiny by regulators and the public. Further, the accounting rules and regulations are continually changing in ways that could materially impact our financial statements. For example, the FASB issued an accounting standards update related to revenue from contracts with customers, which supersedes the revenue recognition requirements in the current Accounting Standards Codification.

We are evaluating the impact of the new standard on our accounting policies, processes, and system requirements and currently plan to adopt the standard using the full retrospective approach. However, a final decision regarding the adoption method has not been finalized at this time. Our final determination will depend on a number of factors, such as the significance of the impact of the new standard on our financial results, system readiness, including that of software procured from third-party providers, and our ability to accumulate and analyze the information necessary to assess the impact on prior period financial statements, as necessary. While we continue to assess the potential impacts of the new standard we anticipate this standard could have a moderate impact on our consolidated financial statements. However, we cannot reasonably estimate quantitative information related to the impact of the new standard on our financial statements at this time. The application of this new guidance may result in a change in the timing and pattern of revenue and cost of sales recognition. We cannot predict the impact of future changes to accounting principles or our accounting policies on our financial statements going forward, which could have a significant effect on our reported financial results, and could affect the reporting of transactions completed before the announcement of the change. In addition, if we were to change our critical accounting estimates, including those related to the recognition of revenue and cost of sales our operating results could be significantly affected.

If we fail to comply with environmental requirements, our business, financial condition, operating results and reputation could be adversely affected.

We are subject to various environmental laws and regulations including laws governing the hazardous material content of our products and laws relating to the collection of and recycling of electrical and electronic equipment. Examples of these laws and regulations include the European Union, or the EU, Restrictions of Hazardous Substances Directive, or the RoHS Directive, and the EU Waste Electrical and Electronic Equipment Directive, or the WEEE Directive, as well as the implementing legislation of the EU member states. Similar laws and regulations have been passed or are pending in China, South Korea, Norway and Japan and may be enacted in other regions, including in the United States, and we are, or may in the future be, subject to these laws and regulations.

The RoHS Directive and the similar laws of other jurisdictions ban the use of certain hazardous materials such as lead, mercury and cadmium in the manufacture of electrical equipment, including our products. We rely on our contract manufacturers to ensure that the manufacturer of our physical appliances and major component part suppliers comply with the RoHS Directive requirements. In addition, if there are changes to this or other laws (or their interpretation) or if new similar laws are passed in other jurisdictions, we may be required to reengineer our products to use components compatible with these laws. This reengineering and component substitution could result in additional costs to us or disrupt our operations or logistics.

The WEEE Directive requires electronic goods producers to be responsible for the collection, recycling and treatment of such products. Changes in the interpretation of the WEEE Directive may cause us to incur costs or have additional regulatory requirements to meet in the future in order to comply with this directive.

Our failure to comply with past, present and future similar laws could result in reduced sales of our products, substantial product inventory write-offs, reputational damage, penalties and other sanctions, which could harm our business and financial condition. We also expect that our products will be affected by new environmental laws and regulations on an ongoing basis. To date, our expenditures for environmental compliance have not had a material impact on our results of operations or cash flows, but, although we cannot predict the future impact of such laws and regulations, they will likely result in additional costs and may increase penalties associated with violations or require us to change the content of our products or how they are manufactured, which could have a material adverse effect on our business, operating results and financial condition.

Changes in our valuation allowance against deferred tax assets may affect our future financial results

We record a valuation allowance to reduce our net deferred tax assets to the amount that we believe is more-likely-than-not to be realized. In assessing the need for a valuation allowance, we considered historical levels of income, expectations and risks associated with estimates of future taxable income and ongoing prudent and practical tax planning strategies. On a periodic basis we evaluate our deferred tax asset balance for realizability. To the extent that we believe it is more-likely-than-not that some portion of our deferred tax assets will not be realized, we will increase the valuation allowance against the deferred tax assets. Realization of our deferred tax assets is primarily dependent upon future taxable income in related tax jurisdictions. If our assumptions and consequently our estimates change in the future, the valuation allowances may be increased or decreased, resulting in a respective increase or decrease in income tax expense. For example, during the three months ended July 2, 2016, we considered all available positive and negative evidence in making a determination to release $30.5 million of the then existing valuation allowance.

As of September 30, 2017, we assessed that it is more-likely-than-not that we will realize our federal and a portion of our state deferred tax assets based on sufficient positive objective evidence that we would generate sufficient taxable income in our U.S. tax jurisdiction to realize the deferred tax assets. Such evidence included, among others, our history

of profitability and losses, jurisdictional income recognition trends, pretax losses adjusted for certain other items, and forecasted income by jurisdiction. Accordingly, we only have a valuation allowance set up against a portion of our state deferred tax assets (see Note 8 of the Notes to Condensed Consolidated Financial Statements in Part I - Item 1 of this Quarterly Report on Form 10-Q).

New regulations related to conflict minerals may cause us to incur additional expenses and could limit the supply and increase the costs of certain metals used in the manufacturing of our products.

As a public company, we are subject to new requirements under the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, or the Dodd-Frank Act, which requires us to diligence, disclose, and report whether or not our products contain conflict minerals. As a recently public company, we filed our initial report with respect to conflict minerals on May 26, 2016 for the 2015 calendar year. The implementation of these new requirements could adversely affect the sourcing, availability and pricing of the materials used in the manufacture of components used in our products. In addition, we have incurred, and will continue to incur, additional costs to comply with the disclosure requirements, including costs related to (i) conducting diligence procedures to determine the sources of conflict minerals that may be used or necessary to the production of our products and, if applicable, (ii) potential changes to products, processes or sources of supply as a consequence of such verification activities. It is also possible that we may face reputational harm if we determine that certain of our products contain minerals not determined to be conflict-free or if we are unable to alter our products, processes or sources of supply to avoid such materials.

The requirements of being a public company may strain our resources, divert management’s attention and affect our ability to attract and retain executive management and qualified board members.

As a public company, we are subject to the reporting requirements of the Exchange Act, the Sarbanes-Oxley Act, the Dodd-Frank Act, the listing requirements of the New York Stock Exchange and other applicable securities rules and regulations. Compliance with these rules and regulations may continue to increase our (i) legal and financial compliance costs, (ii) make some activities more difficult, time-consuming or costly and (iii) increase demand on our systems and resources, particularly as we ceased to be an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act of 2012 on December 26, 2015. The Exchange Act requires, among other things, that we file annual, quarterly and current reports with respect to our business and operating results. The Sarbanes-Oxley Act requires, among other things, that we maintain effective disclosure controls and procedures and internal control over financial reporting. In order to maintain and, if required, improve our disclosure controls and procedures and internal control over financial reporting to meet this standard, significant resources and management oversight will be required. As a result, management’s attention may be diverted from other business concerns, which could adversely affect our business and operating results. Additionally, beginning with our Annual Report on Form 10-K for fiscal 2015, our independent registered public accounting firm has been required to attest to the effectiveness of our internal control over financial reporting pursuant to Section 404 of the Sarbanes-Oxley Act. Although we have already hired additional employees to comply with these requirements, we may need to hire more employees in the future or engage outside consultants, which will increase our costs and expenses.

In addition, changing laws, regulations and standards relating to corporate governance and public disclosure are creating uncertainty for public companies, increasing legal and financial compliance costs and making some activities more time consuming. These laws, regulations and standards are subject to varying interpretations, in many cases due to their lack of specificity, and, as a result, their application in practice may evolve over time as new guidance is provided by regulatory and governing bodies. This could result in continuing uncertainty regarding compliance matters and higher costs necessitated by ongoing revisions to disclosure and governance practices. We intend to invest resources to comply with evolving laws, regulations and standards, and this investment may result in increased general and administrative expenses and a diversion of management’s time and attention from revenue-generating activities to compliance activities. If our efforts to comply with new laws, regulations and standards differ from the activities intended by regulatory or governing bodies due to ambiguities related to their application and practice, regulatory authorities may initiate legal proceedings against us and our business may be adversely affected.

Our business is subject to the risks of earthquakes, fire, power outages, floods and other catastrophic events, and to interruption by manmade problems such as terrorism.

A significant natural disaster, such as an earthquake, fire or a flood, or a significant power outage could have a material adverse impact on our business, operating results and financial condition. Our corporate headquarters are located in the San Francisco Bay Area, a region known for seismic activity. In addition, natural disasters could affect our manufacturing vendors or logistics providers’ ability to perform services such as manufacturing products on a timely basis and assisting with shipments on a timely basis. In the event our service providers’ information technology systems or manufacturing or logistics abilities are hindered by any of the events discussed above, shipments could be delayed, resulting in missing financial targets, such as revenue and shipment targets, for a particular quarter. Further, if a natural

disaster occurs in a region from which we derive a significant portion of our revenue, end-user customers in that region may delay or forego purchases of our products, which may materially and adversely impact our operating results for a particular period. In addition, acts of terrorism could cause disruptions in our business or the business of our manufacturer, logistics providers, partners, end-user customers or the economy as a whole. Given our typical concentration of sales at each quarter end, any disruption in the business of our manufacturer, logistics providers, partners or customers that impacts sales at the end of our quarter could have a significant adverse impact on our quarterly results. All of the aforementioned risks may be heightened if the disaster recovery plans for us and our suppliers prove to be inadequate. To the extent that any of the above results in delays or cancellations of customer orders, or delays in the manufacture, deployment or shipment of our products, our business, financial condition and operating results would be adversely affected.

Risks Relating to Owning Our Common Stock

Our actual operating results may differ significantly from our guidance.

From time to time, we have released, and may continue to release guidance in our quarterly earnings conference call, quarterly earnings releases, or otherwise, regarding our future performance that represents our management’s estimates as of the date of release. This guidance, which includes forward-looking statements, has been and will be based on projections prepared by our management.

Projections are based upon a number of assumptions and estimates that, while presented with numerical specificity, are inherently subject to significant business, economic and competitive uncertainties and contingencies, many of which are beyond our control and are based upon specific assumptions with respect to future business decisions, some of which will change. We intend to state possible outcomes as high and low ranges which are intended to provide a sensitivity analysis as variables are changed but are not intended to imply that actual results could not fall outside of the suggested ranges. The principal reason that we release guidance is to provide a basis for our management to discuss our business outlook with analysts and investors. We do not accept any responsibility for any projections or reports published by any such third parties.

Guidance is necessarily speculative in nature, and it can be expected that some or all of the assumptions underlying the guidance furnished by us will not materialize or will vary significantly from actual results. Accordingly, our guidance is only an estimate of what management believes is realizable as of the date of release. Actual results may vary from our guidance and the variations may be material. For example, for the third quarter of fiscal 2017, the fourth quarter of fiscal 2016 and the first and second quarters of fiscal 2014, we announced results that fell below our guidance and below analyst expectations, which, in most instances, resulted in sharp declines in our stock price. If we fail to meet such expectations in the future, the market price of our common stock could again fall substantially and we could face costly lawsuits, including securities class action litigation. We undertake no obligation to make revisions or publicly update our guidance in advance of actual results unless required by law. In light of the foregoing, investors are urged to consider all of the information we make publicly available in making an investment decision regarding our common stock and not rely solely upon our guidance.

Any failure to successfully implement our operating strategy or the occurrence of any of the events or circumstances set forth in this “Risk Factors” section could result in the actual operating results being different from our guidance, and the differences may be adverse and material.

Our share price has been and may continue to be volatile, and you could lose all or part of your investment.

Technology stocks have historically experienced high levels of volatility. The trading price of our common stock has been and is likely to continue to be highly volatile and subject to wide fluctuations in response to various factors, some of which are beyond our control and may not be related to our operating performance. Since shares of our common stock were sold in our initial public offering in June 2013 at a price of $19.00 per share, the reported high and low sales prices of our common stock have ranged from $9.95 to $61.25 through September 30, 2017. These fluctuations could cause you to lose all or part of your investment in our common stock. Factors that may cause the market price of our common stock to fluctuate 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 or repurchase of large blocks of our stock;


•	departures of key personnel; and


•	issues or perceived issued regarding the consummation of the Merger.

In addition, if the market for technology stocks, or the stock market in general, experiences a loss of investor confidence, the trading price of our common stock could decline for reasons unrelated to our business, operating results or financial condition. The trading price of our common stock might also decline in reaction to events that affect other companies in our industry even if these events do not directly affect us.

In the past, following periods of volatility in the market price of a company’s securities, securities class action litigation has often been brought against that company. If our stock price is volatile, we may become the target of additional securities litigation (including a recent purported shareholder class action lawsuit filed against us on January 27, 2017). Securities litigation could result in substantial costs and divert our management’s attention and resources from our business, and this could have a material adverse effect on our business, operating results and financial condition.

Sales of outstanding shares of our common stock into the market in the future could cause the market price of our common stock to drop significantly.

If our existing stockholders sell, or indicate an intention to sell, substantial amounts of our common stock in the public market, the trading price of our common stock could decline. There were 37,308,868 shares of common stock outstanding as of September 30, 2017, all of which are freely tradable, unless such shares are held by “affiliates,” as that term is defined in Rule 144 of the Securities Act of 1933, as amended.

In addition, we have filed registration statements to register all shares subject to options or RSUs that are currently outstanding or that are reserved for future issuance under our equity compensation plans. If these additional shares are sold, or if it is perceived that they will be sold, in the public market, the trading price of our common stock could decline.

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 could be influenced by any research and reports that securities or industry analysts publish about us or our business. Securities and industry analysts have only relatively recently commenced research coverage of us. In the event securities or industry analysts who cover our company 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 cease coverage of our company or fail to publish reports on us regularly, demand for our stock could decrease, which could cause our stock price and trading volume to decline.

We do not intend to pay dividends in the foreseeable future.

We intend to retain any earnings to finance the operation and expansion of our business, and we do not anticipate paying any cash dividends on our common stock for the foreseeable 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.

Provisions in our certificate of incorporation and bylaws and certain provisions 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 and 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.
