Notes to Condensed Consolidated Financial Statements
(unaudited)



1. Description of Business and Summary of Significant Accounting Policies
Description of Business

A10 Networks, Inc. (together with our subsidiaries, the “Company”, “we”, “our” or “us”) was incorporated in
California in 2004 and reincorporated in Delaware in March 2014. We are headquartered in San Jose, California and have wholly-owned subsidiaries throughout the world including Asia and Europe. Our solutions enable enterprises, service providers, Web giants and government organizations to accelerate, secure and optimize the performance of their data center applications and networks. We currently offer three software based advanced application networking solutions. These are Application Delivery Controllers, or ADCs, to optimize data center performance; Carrier Grade Network Address Translation, or CGN, to provide address and protocol translation services for service provider networks; and a Distributed Denial of Service Threat Protection System, or TPS, for network-wide security protection. We deliver these solutions both on optimized hardware appliances and as virtual appliances across our Thunder Series and AX Series product families.

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements include the accounts of A10 Networks, Inc., and our wholly owned subsidiaries. All inter-company balances and transactions have been eliminated in consolidation.

We had no comprehensive income (loss) other than our net income (loss), hence our comprehensive income (loss) is the same as the net income (loss) for all periods presented. Pursuant to the accounting guidance provided by Accounting Standard Codification ("ASC") 220 Comprehensive Income, we did not present statements of comprehensive income (loss) for the periods presented.

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and following the requirements of the Securities and Exchange Commission (“SEC”) for interim reporting. As permitted under those rules, certain notes or other financial information that are normally required by U.S. GAAP can be condensed or omitted. These financial statements have been prepared on the same basis as our annual financial statements and, in the opinion of management, reflect all adjustments, consisting only of normal recurring adjustments that are necessary for a fair presentation of our financial information. The results of operations for the three and nine months ended September 30, 2015 are not necessarily indicative of the results to be expected for the year ending December 31, 2015 or for any other interim period or for any other future year. The balance sheet as of December 31, 2014 has been derived from audited financial statements at that date but does not include all of the information required by U.S. GAAP for complete financial statements.

The accompanying unaudited condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements for the year ended December 31, 2014, which are included in the Annual Report on Form 10-K filed with the SEC on March 11, 2015.

Use of Estimates

The preparation of the condensed consolidated financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Those estimates and assumptions affect revenue recognition and deferred revenue, allowance for doubtful accounts, sales return reserve, valuation of inventory, contingencies and litigation, and determination of fair value of stock-based compensation. These estimates are based on information available as of the date of the condensed consolidated financial statements; therefore, actual results could differ from management’s estimates.

Summary of Significant Accounting Policies

There have been no changes to the significant accounting policies described in the 2014 Annual Report on Form 10-K that have had a material impact on our condensed consolidated financial statements and related notes.

Concentration of Credit Risk and Significant Customers

Financial instruments that potentially subject us to concentrations of credit risk consist of cash, cash equivalents and accounts receivable. Our cash and cash equivalents are invested in high-credit quality financial instruments with banks and financial institutions. Management believes that the financial institutions that hold our cash and cash equivalents are financially sound and, accordingly, are subject to minimal credit risk. Such deposits may be in excess of insured limits provided on such deposits.

Our accounts receivable are unsecured and represent amounts due to us based on contractual obligations of our customers. We mitigate credit risk in respect to accounts receivable by performing periodic credit evaluations of our customers to assess the probability of accounts receivable collection based on a number of factors, including past transaction experience with the customer, evaluation of their credit history, limiting the credit extended and review of the invoicing terms of the contract. We generally do not require our customers to provide collateral to support accounts receivable.

Significant customers, including distribution channel partners and direct customers, are those which represent more than 10% of our total revenue for each period presented or our gross accounts receivable balance as of each respective balance sheet date. Revenue from our significant customers as a percentage of our total revenue for the three and nine months ended September 30, 2015 and 2014 are as follows:

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

2015
 
2014
Customer A

13%
 
*
 
14%
 
* represents less than 10% of total revenue

As of September 30, 2015 and December 31, 2014, no customer accounted for 10% or more of our total gross accounts receivable.

Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standard Update ("ASU") No. 2014-09, Revenue from Contracts with Customers, which provides new guidance on the recognition of revenue and states that an entity should recognize revenue to depict the transfer of promised 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. The updated standard will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective and permits the use of either the retrospective or cumulative effect transition method. The original effective date of this accounting standard was annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. In August 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers: Deferral of the Effective Date, which deferred the effective date of the new revenue standard for periods beginning after December 15, 2016 to December 15, 2017, with early adoption permitted but not earlier than the original effective date. This updated standard is effective for us on January 1, 2018. We are currently evaluating the impact of the adoption of this accounting standard update on our consolidated financial position or results of operations and method of adoption.

In April 2015, the FASB issued 2015-03 Interest—Imputation of Interest (Subtopic 835-30) Simplifying the Presentation of Debt Issuance Costs and during August 2015, the FASB issued ASU No. 2015-15, Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements, which clarifies the treatment of debt issuance costs from line-of-credit arrangements after adoption of ASU No. 2015-03. This accounting guidance requires debt issuance costs be presented on the balance sheet as a direct reduction from the carrying amount of the related debt liability. ASU No. 2015-15 clarifies that the SEC staff would not object to an entity deferring and presenting debt issuance costs as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. ASU No. 2015-03 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. We believe the adoption of ASU No. 2015-15 will not have a material effect on our consolidated financial statements.


6


In July 2015, the FASB issued ASU No. 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory. Under this accounting guidance, inventory will be measured at the lower of cost and net realizable value and other options that currently exist for market value will be eliminated. ASU No. 2015-11 defines net realizable value as the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. No other changes were made to the current guidance on inventory measurement. This accounting guidance is effective for us in the first quarter of 2017. Early adoption is permitted. We are currently evaluating the impact of the adoption of this accounting standard update on our consolidated financial statements.

There have been no other recent accounting pronouncements or changes in accounting pronouncements during the nine months ended September 30, 2015, as compared to the recent accounting pronouncements described in our Annual Report on Form 10-K for the year ended December 31, 2014 filed with SEC on March 11, 2015, that are of significance or potential significance to us.

2. Fair Value Measurements

Our financial instruments consist of cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities. Cash equivalents, which include money market funds, are stated at amortized cost, which approximates fair value as of the balance sheet dates, due to the short period of time to maturity. Accounts receivable, accounts payable and accrued liabilities are stated at their carrying value, which approximates fair value due to the short time to the expected receipt or payment.

Cash and cash equivalents are carried at fair value. Our money market funds are classified within Level I of the fair value hierarchy, as these instruments are valued using quoted market prices. Specifically, we value our investments in money market securities based on quoted market prices in active markets. As of September 30, 2015 and December 31, 2014, we had no assets or liabilities classified within Level II or Level III and there were no transfers of instruments between Level I, Level II and Level III regarding fair value measurement.

The following table sets forth the fair value of our financial assets measured on a recurring basis, by level, within the fair value hierarchy (in thousands):

4. Credit Facility
In September 2013, we entered into a credit agreement with Royal Bank of Canada, JPMorgan Chase Bank, N.A. and Bank of America, N.A. as lenders. The credit agreement provides a three-year, $35.0 million, revolving credit facility, which includes a maximum $10.0 million letter of credit facility. As of September 30, 2015 and December 31, 2014, we have no outstanding borrowings under this credit facility.
Our obligations under the credit agreement are secured by a security interest on substantially all of our assets, including our intellectual property. The credit agreement contains customary financial and non-financial covenants, and are described in Note 4, Credit Facility of the Notes to Consolidated Financial Statements of our Annual Report on Form 10-K for

8


the year ended December 31, 2014 filed with the SEC on March 11, 2015. We were in compliance with all financial and nonfinancial covenants under the revolving credit facility as of September 30, 2015.
At our option, the revolving credit facility bears interest at a rate per annum based on either (i) an alternate base rate plus a margin ranging from 1.75% to 2.50% depending on our total leverage ratio, or (ii) the London interbank offered rate, or LIBOR, based on one, two, three or six month interest periods plus a margin ranging from 2.75% to 3.50% depending on our total leverage ratio. The alternate base rate is equal to the greatest of (i) the Royal Bank of Canada’s prime rate, (ii) the federal funds rate plus a margin equal to 0.50% and (iii) the Eurodollar rate for a one month interest period plus a margin equal to 1.00%.
In addition, we incurred $1.0 million of debt issuance costs that were directly attributable to the issuance of this revolving credit facility which will be amortized to interest expense over the three-year term of this credit facility. As of September 30, 2015, the unamortized debt issuance costs of $0.3 million were included within other long-term assets in our Condensed Consolidated Balance Sheets. We are also required to pay quarterly facility fees of 0.45% per annum on the average daily unused portion of the revolving credit facility.

5. Commitments and Contingencies

Legal Proceedings

From time to time, we may be party or subject to various legal proceedings and claims, either asserted or unasserted, which arise in the ordinary course of business, including proceedings and claims that relate to intellectual property matters. Some of these proceedings involve claims that are subject to substantial uncertainties and unascertainable damages. Accordingly, except as disclosed, we have not established reserves or ranges of possible loss related to these proceedings, as at this time in the proceedings, if any, the matters do not relate to a probable loss and/or amounts cannot be reasonably estimated.

 In November 2013, Parallel Networks, LLC (“Parallel Networks”), which we believe is a non-practicing patent holding company, filed a lawsuit against us in the United States District Court for the District of Delaware, alleging that our AX and Thunder series products infringe two of their U.S. patents. In June 2015, we entered into a settlement agreement whereby we obtained a fully-paid up license and the case was dismissed.
 
On January 29, 2015, the Company, the members of our Board of Directors, our Chief Financial Officer, and the underwriters of our March 21, 2014 Initial Public Offering ("IPO") were named as defendants in a putative class action lawsuit filed in the Superior Court of the State of California, County of Santa Clara, captioned City of Warren Police and Fire Retirement System v. A10 Networks, Inc., et al., 1-15-CV-276207.  Several substantially identical lawsuits were subsequently filed in the same court, bringing the same claims against the same defendants, captioned Arkansas Teacher Retirement System v. A10 Networks, Inc., et al., 1-15-CV-278575 (filed March 25, 2015) and Kaveny v. A10 Networks, Inc., et al., 1-15-CV-279006 (filed April 6, 2015).  On May 29, 2015, the aforementioned putative class actions were consolidated under the caption In re A10 Networks, Inc. Shareholder Litigation, 1-15-CV-276207.  On June 30, 2015, plaintiffs filed a Consolidated Class Action Complaint. The Consolidated Complaint seeks to allege violations of the federal Securities Act of 1933 on behalf of a putative class consisting of purchasers of our common stock pursuant or traceable to the registration statement and prospectus for the initial public offering, and seek unspecified compensatory damages and other relief. On July 31, 2015, the defendants filed demurrers, which the plaintiffs opposed, and which are currently set for a hearing before the Superior Court on November 6, 2015. We intend to vigorously defend these lawsuits.

On June 24, 2015, our directors and certain of our officers were named as defendants in a putative derivative lawsuit filed in the Superior Court of the State of California, County of Santa Clara, captioned Hornung v. Chen, et al., 1-15-CV-282286.  We were also named as a nominal defendant.  The complaint seeks to allege breaches of fiduciary duties and other related claims, arising out of allegations that our officers and directors caused us to infringe patents and intellectual property, improperly approved the settlement of prior litigation, failed to adopt and implement effective internal controls, and caused us to issue false and misleading statements in connection with our IPO. Plaintiff seeks unspecified compensatory damages and other equitable relief. We intend to vigorously defend these lawsuits.

Lease Obligations and Other Commitments

Commencing in 2012, we entered into an equipment financing arrangement with a financial institution whereby the financial institution purchases and leases to us, equipment (primarily computer and network-related) for use in our business. Amounts financed under the leases are accounted for as capital leases. We financed $0.8 million under the arrangement in 2012, which was fully repaid by December 2014. In March 2015, we entered into an agreement to lease an additional $0.3

9


million of equipment under this financing arrangement. The various leased equipment was delivered to us by the end of the third quarter of 2015. As of September 30, 2015, we had $0.3 million in outstanding capital lease obligations. We had no outstanding borrowings under this financing arrangement as of December 31, 2014.

We lease various operating spaces in the United States, Asia, and Europe under non-cancelable operating lease arrangements that expire on various dates through February 2020. These arrangements require us to pay certain operating expenses, such as taxes, repairs, and insurance and contain renewal and escalation clauses. We recognize rent expense under these arrangements on a straight-line basis over the term of the lease.

We have entered into agreements with some of our customers and channel partners that contain indemnification provisions in the event of claims alleging that our products infringe the intellectual property rights of a third party. Other guarantees or indemnification arrangements include guarantees of product and service performance and standby letters of credit for lease facilities and corporate credit cards. We have not recorded a liability related to these indemnification and guarantee provisions and our guarantees and indemnification arrangements have not had any significant impact on our consolidated financial statements to date.

6. Equity Award Plans

Equity Incentive Plans

2014 Equity Incentive Plan

Our 2014 Equity Incentive Plan (the "2014 Plan") was adopted by our Board of Directors and approved by our stockholders in March 2014. The 2014 Plan provides for the granting of stock options, restricted stock awards, restricted stock units, stock appreciation rights, performance units and performance shares to our employees, directors and consultants.

As of December 31, 2014, we had 1,343,743 shares available for future grant. Annually, the shares authorized for the Plan will increase by the least of (i) 8,000,000 shares, (ii) 5% of the outstanding shares of common stock on the last day of our immediately preceding fiscal year, or (iii) such other amount as determined by our Board of Directors. On January 1, 2015, the number of shares in the 2014 Plan was increased by 3,078,645 shares, which represents 5% of the prior year end’s common stock outstanding. In addition, effective as of June 10, 2015, our Board of Directors adopted, and our stockholders approved, an amendment and restatement of our 2014 Plan, which increased the number of shares available for issuance under the 2014 Plan by the number of shares available from the 2008 Plan that were canceled or otherwise forfeited or repurchased by us after March 20, 2014. A maximum of 8,310,566 shares may become available from the 2008 Plan for issuance under the 2014 Plan. As of September 30, 2015, 1,374,975 shares of our common stock were eligible to be added to the 2014 Plan share reserve in accordance with the amendment and restatement of the 2014 Plan. During the nine months ended September 30, 2015, we granted 408,500 stock options and 1,295,806 restricted stock units ("RSUs") under the 2014 Plan to our employees, directors and consultants. As of September 30, 2015, we have 3,532,415 shares available for future grant, excluding shares eligible to be added from the 2008 Plan.

2014 Employee Stock Purchase Plan

The 2014 Employee Stock Purchase Plan (the "2014 Purchase Plan") was adopted by our Board of Directors and approved by our stockholders in March 2014.

As of December 31, 2014, we had 1,031,316 shares available for future purchase. Under the provisions of the 2014 Purchase Plan, on the first day of each fiscal year, starting with January 1, 2015, the number of shares in the reserve will increase by the lesser of (i) 3,500,000 shares, (ii) 1% of the outstanding shares of our common stock on the last day of the immediately preceding fiscal year, or (iii) such other amount as determined by our Board of Directors or other committee administering the 2014 Purchase Plan. In January 2015, we increased common shares reserved for future purchase by 615,729 shares in accordance with the provision of the 2014 Purchase Plan. The participants of the plan purchased 542,102 shares during the nine months ended September 30, 2015, and as of September 30, 2015, we have 1,104,943 shares available for future purchase.

Stock-based Compensation

Stock-based compensation is based on the estimated fair value of awards, net of estimated forfeitures, and recognized over the requisite service period. The following is a summary of stock-based compensation for stock-based awards granted under the 2014 Plan, the 2008 Plan, and employee stock purchases under the 2014 Purchase Plan recognized during the three and nine months ended September 30, 2015 and 2014 (in thousands):

At September 30, 2015, we had $26.6 million of unrecognized stock-based compensation expense, net of estimated forfeitures, related to stock options, unvested restricted stock units and 2014 Purchase Plan purchases. This unamortized stock-based compensation expense will be recognized over a weighted-average period of 2.6 years.

Determination of Fair Value

We use the Black-Scholes option pricing model to determine the grant date fair value of stock options and stock purchases and generally recognize stock-based compensation expense on a straight-line basis over the requisite service period.

The determination of the fair value on the date of grant is affected by the estimated underlying common stock price, as well as assumptions regarding a number of complex and subjective variables. These variables include expected stock price volatility over the term of the awards, actual and projected employee stock option exercise behaviors, risk-free interest rates, and expected dividends.

The fair value of the stock options and employee stock purchases were determined using the Black-Scholes option pricing model and assumptions discussed below. Each of these inputs is subjective and generally requires significant judgment to determine.

Expected Term. We estimate the expected life of options based on an analysis of our historical experience of employee exercise and post-vesting termination behavior considered in relation to the contractual life of the option. The expected term for the 2014 Purchase Plan is based on the term of the purchase period.

Risk-Free Interest Rate. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for zero coupon U.S. Treasury notes with maturities approximately equal to the expected terms of stock options and shares to be issued under the 2014 Purchase Plan.

Expected Volatility. Due to the limited trading history of our own common stock, we determined the share price volatility factor based on a combination of the historical volatility of our own common stock and the historical volatility of our peer group.

Dividend Rate. The expected dividend was assumed to be zero as we have never paid dividends and have no current plans to do so.

11



We estimate the fair value of RSUs using the closing market price of our common stock on the grant date.

(1) Common shares granted under the 2008 Plan and canceled after March 20, 2014 are reallocated to the 2014 Plan’s share reserve as they become available for issuance under the 2014 Plan. During the nine months ended September 30, 2015, 469,440 shares of the canceled stock options were eligible to be reallocated to the 2014 Plan share reserve.

As of September 30, 2015, the aggregate intrinsic value represents the excess of the closing price of our common stock of $5.99 over the exercise price of the outstanding in-the-money options.

The aggregate intrinsic value is the amount that would have been received by the unit holders had all RSUs been vested and released on September 30, 2015. This amount will fluctuate based on the fair market value of our stock.

Market Performance-based Restricted Stock Units

We granted MSUs covering 540,000 shares and 40,000 shares of our common stock to certain company executives during 2014 and the nine months ended September 30, 2015, all of which were outstanding as of September 30, 2015. These MSUs will vest if the closing price of our common stock remains above certain predetermined target prices for 20 consecutive trading days within a 4-year period following the award’s grant date, subject to continued service by the award holder.

The total aggregate intrinsic value for the MSUs granted was $3.5 million, which represents the total pre-tax intrinsic value (calculated by multiplying our closing stock price on the last trading day of the period by the number of unvested MSUs) that would have been received by the award holders had all MSUs vested and been released on September 30, 2015. This amount will fluctuate based on the fair market value of our stock. No MSUs were vested or released during the nine months ended September 30, 2015.

Employee Stock Purchase Plan

The fair value of the option component of the 2014 Purchase Plan shares was determined at the grant date using the Black-Scholes option pricing model with the following weighted average assumptions:

8. Income Taxes

We recorded income tax expense of $0.2 million and $0.5 million for the three and nine months ended September 30, 2015, which was primarily comprised of state and foreign taxes. We recorded income tax expense of $0.2 million and $0.7 million for the three and nine months ended September 30, 2014, which was primarily comprised of state and foreign taxes. Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the carrying amounts of existing assets and liabilities in the financial statements and their respective tax bases using tax rates expected to be in effect during the years in which the basis differences reverse.

We believe it is more likely than not that our federal and state net deferred tax assets will not be fully realized. In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of a deferred tax asset will be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. A valuation allowance is recorded for loss carryforwards and other deferred tax assets where it is more likely than not that such deferred tax assets will not be realized. Accordingly, we continue to maintain a valuation allowance against all of our net deferred tax assets as of September 30, 2015. Due to past losses in the U.S., we have a full valuation allowance on the U.S. federal and state deferred tax assets. We will continue to maintain a full valuation allowance against our net federal, state and certain foreign deferred tax assets until there is sufficient evidence to support recoverability of our deferred tax assets.


14


We had $2.4 million and $2.2 million of unrecognized tax benefits as of September 30, 2015 and December 31, 2014.  We do not anticipate a material change to our unrecognized tax benefits over the next twelve months. Unrecognized tax benefits may change during the next twelve months for items that arise in the ordinary course of business.

10. Related-Party Transactions

An affiliate of one of our significant stockholders is also acting as a reseller of our products. On May 27, 2015, the significant stockholder reduced its ownership of our common stock, and ceased to be a related party as its ownership percentage dropped to below 5%. During the nine months ended September 30, 2015, we recognized $2.2 million of revenue from this reseller while it was a related party. During the three and nine months ended September 30, 2014, we recognized $0.8 million and $2.0 million of total revenue from this reseller.
 
We had gross accounts receivable of $0.4 million from this reseller as of December 31, 2014.

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

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our condensed consolidated financial statements and related notes appearing elsewhere in this Quarterly Report on Form 10-Q. The following discussion and analysis contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. The words “believe,” “may,” “will,” “potentially,” “estimate,” “continue,” “anticipate,” “intend,” “could,” “would,” “project,” “plan” “expect,” and similar expressions that convey uncertainty of future events or outcomes are intended to identify forward-looking statements.
These forward-looking statements include, but are not limited to, statements concerning the following:
our ability to maintain an adequate rate of revenue growth;
our ability to successfully anticipate market needs and opportunities;
our business plan and our ability to effectively manage our growth;
costs associated with defending intellectual property infringement and other claims;
our ability to attract and retain end-customers;
loss or delay of expected purchases by our largest end-customers;
our ability to further penetrate our existing customer base;
our ability to displace existing products in established markets;
our ability to expand our leadership position in next-generation application delivery and server load balancing solutions;
continued growth in markets relating to network security;
our ability to timely and effectively scale and adapt our existing technology;
our ability to innovate new products and bring them to market in a timely manner;
our ability to expand internationally;
the effects of increased competition in our market and our ability to compete effectively;
the effects of seasonal trends on our results of operations;

future acquisitions of or investments in complementary companies, products, services or technologies.
These forward-looking statements are subject to a number of risks, uncertainties, and assumptions, including those described in “Risk Factors” and elsewhere in this Quarterly Report on Form 10-Q. Moreover, we operate in a very competitive and rapidly changing environment, and new risks emerge from time to time. It is not possible for our management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make. In light of these risks, uncertainties, and assumptions, the forward-looking events and circumstances discussed in this Quarterly Report on Form 10-Q may not occur and actual results could differ materially and adversely from those anticipated or implied in the forward-looking statements.
You should not rely upon forward-looking statements as predictions of future events. Although we believe that the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee that the future results, levels of activity, performance or events and circumstances reflected in the forward-looking statements will be achieved or occur.

Overview

We are a leading provider of application networking technologies. Our solutions enable service providers, enterprises, Web giants and government organizations to accelerate, secure and optimize the performance of their data center applications and networks. Our products are built on our Advanced Core Operating System ("ACOS") platform of advanced network technologies, which is designed to enable our products to deliver substantially greater performance and security relative to prior generation application networking products. Our software based ACOS architecture also provides the flexibility that enables us to expand our business to offer additional products to solve a growing array of networking and security challenges arising from increased Internet cloud and mobile computing.

We currently offer three software based advanced application networking solutions. These are Application Delivery Controllers ("ADCs") to optimize data center performance, Carrier Grade Network Address Translation ("CGN") to provide address and protocol translation services for service provider networks, and a Distributed Denial of Service Threat Protection System ("TPS") for network-wide security protection. We deliver these solutions both on optimized hardware appliances and as virtual appliances across our Thunder Series and AX Series product families.

We derive revenue from sales of products and related support services. Product revenue is generated primarily by sales of hardware appliances with perpetual licenses to our embedded software solutions. We generate services revenue primarily from sales of maintenance and support contracts. Our end customers predominantly purchase maintenance and support in conjunction with purchases of our products. In addition, we also derive revenues from the sale of professional services.

We sell our products globally to service providers and enterprises that depend on data center applications and networks to generate revenue and manage operations efficiently. Our end customers operate in a variety of industries, including telecommunications, technology, industrial, retail, financial, education and government. Since inception, our customer base has grown rapidly. As of September 30, 2015, we had sold products to approximately 4,500 customers across 73 countries.

We sell substantially all of our solutions through our high-touch sales organization as well as distribution channel partners, including distributors, value added resellers and system integrators, and fulfill nearly all orders globally through such partners. We believe this sales approach allows us to obtain the benefits of channel distribution, such as expanding our market coverage, while still maintaining face-to-face relationships with our end-customers. We outsource the manufacturing of our hardware products to original design manufacturers. We perform quality assurance and testing at our San Jose, Taiwan and Japan distribution centers, as well as at our manufacturers’ locations. We warehouse and deliver our products out of our San Jose warehouse for the Americas. We outsource warehousing and delivery to third-party logistics providers for delivery in other regions.

During the first nine months of 2015, 53% of our total revenue was generated from the United States, 17% from Japan, and 30% from other geographical regions. During the first nine months of 2014, 48% of our total revenue was generated from the United States, 27% from Japan and 25% from other geographical regions. Our enterprise customers accounted for 58% and 51% of our total revenue during the first nine months of 2015 and 2014. Our service provider customers accounted for 42% and 49% of our total revenue during the first nine months of 2015 and 2014.

As a result of the nature of our target market and the current stage of our development, a substantial portion of our revenue comes from a limited number of large end-customers, including service provers, in any period. During the first nine months of 2015 and 2014, purchases from our ten largest end-customers accounted for approximately 30% and 41% of our total revenue. Sales to these large end-customers have typically been characterized by large but irregular purchases with long sales cycles. The timing of these purchases and the delivery of the purchased products is difficult to predict. As a consequence, any acceleration or delay in anticipated product purchases by, or deliveries to, our largest end customers could materially impact our revenue and operating results in any quarterly period. This may cause our quarterly revenue and operating results to fluctuate from quarter to quarter and make them difficult to predict.

We had $100.5 million of cash and cash equivalents as of September 30, 2015. Cash generated by operating activities was $7.6 million in the first nine months of 2015 compared to $13.5 million of cash used in operating activities in the same period of 2014.

We intend to continue to invest for long-term growth. We have invested in, and expect to continue to invest in, our product development efforts to deliver new products and additional features in our current products to address customer needs. In addition, we expect to continue to expand our global sales and marketing organizations, expand our distribution channel partner programs, and increase awareness of our solutions on a global basis. Additionally, we will be investing in general and administrative resources to meet the requirements to operate as a public company. Our investments in growth in these areas may affect short-term profitability.

Revenue

Our product revenue primarily consists of revenue from sales of our hardware appliances upon which our software is installed. Such software includes our ACOS software platform plus one of our ADC, CGN or TPS solutions. Purchase of a hardware appliance includes a perpetual license to the included software. We recognize product revenue at the time of shipment, provided that all other revenue recognition criteria have been met. As a percentage of revenue, our product revenue may vary from quarter to quarter based on, among other things, the timing of orders and delivery of products, cyclicality and seasonality, changes in currency exchange rates and the impact of significant transactions with unique terms and conditions.

We generate services revenue from sales of post contract support, or PCS, which is bundled with sales of products and professional services. We offer tiered PCS services under renewable, fee-based PCS contracts, primarily including technical support, hardware repair and replacement parts, and software upgrades on a when-and-if-released basis. We recognize services revenue ratably over the term of the PCS contract, which is typically one year, but can be up to five years. We expect our services revenue to increase in absolute dollars as we expand our installed base.

A summary of our total revenue for the three and nine months ended September 30, 2015 and 2014 is as follows (in thousands, except for percentages):

Total revenue increased by $7.4 million in the third quarter of 2015 compared to the third quarter of 2014, which was comprised of a $3.4 million increase in product revenue and a $4.0 million increase in services revenue. Revenue from service

20


providers and enterprise customers increased 19% and 16%, respectively, in the third quarter of 2015 compared to the same period in 2014.

Product revenue increased $3.4 million, or 11%, in the third quarter of 2015 compared to the third quarter in 2014 which is primarily attributable to increases from the United States, EMEA and Asia Pacific, excluding Japan, largely due to higher product revenue from service provider customers. These revenue increases were partially offset by lower product revenue from Japan. Japan's product revenue decreased in the third quarter of 2015 compared to the same period in 2014 largely due to the impact of unfavorable currency exchange rate between the Japanese yen and the U.S. dollar and lower product revenues.

Services revenue increased $4.0 million, or 33% in the third quarter of 2015 compared to the same period in 2014 primarily attributable to the increase in PCS sales in connection with our increasing installed customer base as well as increases in our professional services revenue. Over 95% of our end-customers purchase one of our maintenance service products when purchasing our hardware products. During the third quarter of 2015, services revenue recognized from contracts existing prior to 2015 grew by 35% as compared to services revenue related to contracts existing prior to 2014.

During the third quarter of 2015, $25.1 million, or 49%, of total revenue was generated from the United States, which represents a 23% growth compared to the third quarter of 2014. This increase was primarily attributable to increased product revenue from service provider customers as well as higher PCS sales in connection with our increased installed customer base. We continue to see growth in our EMEA and Asia Pacific regions, excluding Japan. In the third quarter of 2015, total revenue from EMEA and Asia Pacific region, excluding Japan, increased 48% and 27%, respectively, compared to the third quarter of 2014, primarily due to our efforts to continue expanding our presence in these regions. During the third quarter of 2015, 17%, or $8.8 million of total revenue was generated from Japan, an 11% decrease compared to the third quarter of 2014, primarily due to lower product revenues. In addition, Japan's third quarter 2015 total revenue was also was more adversely impacted by the unfavorable currency exchange rate between the Japanese yen against the U.S. dollar compared to the same period in 2014.

Total revenue increased by $8.0 million in the first nine months of 2015 compared to the same period of 2014, which comprised of an $11.3 million increase in services revenue, partially offset by a $3.3 million decrease in product revenue. Revenue from enterprise customers increased 13% in the first nine months of 2015 compared to the same period in 2014. Revenue from service provider customers decreased 2% in the first nine months of 2015 compared to the same period in 2014.

Product revenue decreased $3.3 million, or 3%, in the first nine months of 2015 compared to the same period in 2014 which is primarily attributable to lower product revenue from Japan, partially offset by product revenue increases from the United States, EMEA and Asia Pacific, excluding Japan. In the first quarter of 2014, our product revenue from Japan was positively impacted by a higher backlog entering the quarter that resulted from strong demand for our products in Japan in the fourth quarter of 2013. In addition, Japan's total revenue was more adversely impacted by the unfavorable currency exchange rate between the Japanese yen against the U.S. dollar in the third quarter of 2015 compared to the same period in 2014.

Services revenue increased $11.3 million, or 35%, in the first nine months of 2015 compared to the same period in 2014, primarily attributable to the increase in PCS sales in connection with our increasing installed customer base, as well as increases in our professional services revenue. Over 95% of our end-customers purchase one of our maintenance service products when purchasing our hardware products. During the first nine months of 2015, services revenue recognized from contracts existing prior to 2015 grew by 36% as compared to services revenue related to contracts existing prior to 2014.

During the first nine months of 2015, 53%, or $75.4 million of total revenue was generated from the United States, which represents a 16% growth compared to the same period in 2014. This increase was primarily attributable to increased product revenue from service provider customers as well as higher PCS sales in connection with our increased installed customer base. We continue to see growth in our EMEA and Asia Pacific regions, excluding Japan, with total revenue increasing 57% and 21%, respectively, in the first nine months of 2015 compared to the same period of 2014, primarily due to our efforts to continue expanding our presence in these regions. During the first nine months of 2015, 17%, or $24.2 million of total revenue was generated from Japan, a 32% decrease compared to the same period in 2014 primarily due to lower product revenue as a result of the positive impact of higher backlog entering into 2014. This decrease was partially offset by an increase in services revenue. In addition, Japan's total revenue was more adversely impacted by the unfavorable currency exchange rate between the Japanese yen against the U.S. dollar during the first nine months of 2015 compared to the same period in 2014.

Gross Margin

Gross margin varies from period to period due to a variety of factors. These may include the mix of revenue from each of our regions, the mix of our products sold within a period, discounts provided to customers, inventory write-downs and foreign currency exchange rates.

Our sales are generally denominated in U.S. dollars, however, in Japan they are denominated in the Japanese yen. Changes in the exchange rates between the U.S. dollar and Japanese yen will therefore affect our revenue and gross margin. Any of the factors noted above can generate either a positive or negative impact on gross margin as compared to another period.

Products gross margin in the third quarter of 2015 increased by 3.5% compared to the same period in 2014 primarily due to improved product mix and a decrease in inventory reserves, partially offset by the impact of unfavorable exchange rates of Japanese yen against the U.S. dollar. In the third quarter of 2014, our products gross margins was negatively impacted due to an increase in our inventory reserves as a result of our end-customers adopting our new Thunder Series.

Products gross margin decreased 0.6% in the first nine months of 2015 compared to the same period in 2014 primarily due to the impact of unfavorable exchange rates of Japanese yen against the U.S. dollar partially offset by a favorable shift in our geographical sales mix. In addition, our products gross margins in the third quarter of 2015 were also negatively impacted by investments we made related to two Original Equipment Manufacturers ("OEM") opportunities.

We experienced higher sales volumes from geographic regions with generally higher gross margins during the third quarter and the first nine months of 2015 compared to the same periods in 2014, which had a positive impact on our gross margins for the three and nine months ended September 30, 2015. Our gross margin for the third quarter and the first nine months of 2015 was also impacted by unfavorable foreign exchange rates as the Japanese yen exchange rates continue to devalue against the U.S. dollar. We anticipate that our gross margin will continue to be impacted by these factors in subsequent periods.

Services gross margin decreased 1.7% and 0.3% in the three and nine months ended September 30, 2015 compared to the same periods in 2014, as a result of increases in cost of services partially offset by the growth in services revenue. The increase in cost of services was primarily a result of headcount increase as we continue to expand our services and support teams in anticipation of future growth in our installed base. Our services revenue recognized from our installed base with existing contracts prior to 2015 grew by 36% in the first nine months of 2015 compared to services revenue generated from contracts existing prior to 2014 during the first nine months of 2014.

Operating Expenses

Our operating expenses consist of sales and marketing, research and development, general and administrative and litigation. The largest component of our operating expenses is personnel costs which consist of wages, benefits, bonuses, and, with respect to sales and marketing expenses, sales commissions. Personnel costs also include stock-based compensation and travel expenses.

A summary of our operating expenses for the three and nine months ended September 30, 2015 and 2014 is as follows (in thousands, except for percentages):

Sales and Marketing

Sales and marketing expenses are our largest functional category of total operating expenses. These expenses primarily consist of personnel costs related to our employees engaged in sales and marketing activities. Sales and marketing expenses also include the cost of marketing programs, trade shows, consulting services, promotional materials, demonstration equipment, depreciation and certain allocated facilities and information technology infrastructure costs.

Sales and marketing expenses increased $1.1 million, or 5%, in the third quarter of 2015 compared to the third quarter of 2014 primarily attributable to a $2.2 million increase in personnel related costs which includes a $1.0 million increase in sales commissions and a $0.4 million increase in stock-based compensation. The increase in personnel related costs was largely due to increased sales and marketing headcount and higher bonus attainment and sales commissions in the third quarter of 2015 compared to the same period in 2014. This increase was partially offset by a $0.4 million decrease in market development costs and a $0.4 million decrease in professional services and consultant fees.

Sales and marketing expenses increased $5.1 million, or 7%, in the first nine months of 2015 compared to the same period in 2014 primarily attributable to a $4.8 million increase in personnel related costs and a $0.7 million increase in company meeting expenses. The increase in personnel related costs, which includes a $2.3 million increase in sales commission and a $2.0 million increase in stock-based compensation was primarily attributable to increased sales and marketing headcount and higher bonus attainment and sales commissions in the first nine months of 2015 compared to the same period in 2014. These increases were partially offset by a $0.4 million decrease in trade show and market development costs.

We expect our sales and marketing expenses to continue to increase in absolute dollars in the future as we increase the size of our sales and marketing organization and as we increase our sales presence in existing countries and expand into new countries.

Research and Development

Research and development efforts are focused on new product development and on developing additional functionality
for our existing products. These expenses consist of personnel costs, and to a lesser extent, professional services, prototype materials, depreciation and certain allocated facilities and information technology infrastructure costs. We expense research and development costs as incurred.

Research and development expenses increased $1.2 million, or 10%, in the third quarter of 2015 compared to the third quarter of 2014 primarily attributable to a $1.6 million increase in personnel related costs, which includes a $0.4 million increase in stock-based compensation. The increase in personnel related costs was primarily attributable to higher salaries and benefits. This increase was partially offset by a $0.3 million decrease in depreciation expense as a result of certain assets being fully depreciated.

Research and development expenses increased $6.1 million, or 17%, in the first nine months of 2015 compared to the same period in 2014 primarily attributable to a $7.3 million increase in personnel related costs, which includes a $1.8 million increase in stock-based compensation. The increase in personnel related costs was primarily attributable to higher salaries and benefits. The increase in personnel related research and development expense was partially offset by a $0.7 million decrease in professional services fees due to lower product certification related activities in the first nine months of 2015 compared to the same period in 2014 and a $0.6 million decrease in depreciation expense as a result of certain assets being fully depreciated.

We expect our research and development expenses to increase in absolute dollars in the future as we continue to develop new products and enhance our existing products.

24



General and Administrative

General and administrative expenses consist primarily of personnel costs, professional services fees and office costs. General and administrative personnel costs include executive, finance, human resources, information technology, facility and legal (excluding litigation) related expenses. Professional fees consist primarily of fees for outside accounting, tax, legal, recruiting and other administrative services.

General and administrative expenses increased $1.8 million, or 34%, for the third quarter of 2015 compared to the third quarter of 2014 primarily attributable to a $0.7 million increase in personnel related costs and a $0.9 million increase in bad debt expense.

General and administrative expenses increased $4.1 million, or 25%, for the first nine months of 2015 compared to the same period of 2014 primarily attributable to a $2.4 million increase in personnel related costs, a $1.1 million increase in professional services cost and a $1.8 million increase in bad debt expense. These increases were partially offset by a $1.1 million decrease in sales and use tax expense largely as a result of the completion of several state sales tax registration processes and adjustments resulting from our reassessment of previously accrued sales and use tax liabilities.

The increase in personnel related costs in the three and nine months ended September 30, 2015 compared to the same periods in 2014 was a result of higher general and administrative headcount and increased salaries and benefits.

Based on management’s assessment and historical collection experience with our customer base, we recorded $0.6 million and $1.1 million of bad debt expense during the three and nine months ended September 30, 2015 compared to a reduction of $0.3 million and $0.7 million in bad debt expense in each of the three and nine months ended September 30, 2014.

The increase in professional services fees in the first nine months of 2015 compared to the same period in 2014 was primarily related to increased general legal and consultant fees in connection with scaling our organization to support increased business activity and costs associated with being a public company.

We expect our general and administrative expenses to increase slightly in the future.

Litigation Expense

Litigation expense is comprised of legal expenses incurred related to litigation and, if applicable, charges for litigation reserves. Litigation expenses consist of professional fees incurred in defending ourselves against litigation matters and are expensed as incurred when professional services are provided. The litigation reserve, if any, consists of accruals we make related to estimated losses in pending legal proceedings. Litigation reserves, if any, are adjusted as we change our estimates or make payments in damages or settlements.

Litigation expense decreased $0.4 million for the third quarter of 2015 compared to the third quarter of 2014 primarily attributable to a reduction in litigation related activities.

Litigation expense increased $5.0 million in the first nine months of 2015 compared to the same period of 2014 primarily attributable to the $7.0 million litigation benefit recognized in the second quarter of 2014 following a settlement agreement in May 2014 with one of our legal services providers which resulted in the reduction of a previously accrued contractual liability, partially offset by a $2.0 million decrease in other litigation expense largely attributable to a reduction in litigation related activities in the first nine months of 2015 compared to the same period in 2014.

Interest Expense

Interest expense decreased by $0.5 million in the first nine months of 2015 compared to the same period in 2014, primarily due to lower borrowing related activities in the first nine months of 2015 compared to the same period in 2014. During the first nine months of 2014, we recorded a $0.3 million contingent payment due to a lender upon completion of our initial public offering and $0.2 million of interest expense related to our revolving credit facility. We completed our initial public offering and repaid the outstanding balance under our revolving credit facility in March 2014.


25


Interest Income and Other Income (Expense), Net

Interest income and other income (expense), net, increased by $0.5 million in the third quarter of 2015 compared to the same period in 2014 primarily due to a $0.5 million decrease in foreign exchange losses. Interest income and other income (expense), net, increased by $0.5 million in the first nine months of 2015 compared to the same period in 2014 primarily due to a $0.4 million decrease in foreign exchange losses.
The Japanese yen exchange rates declined significantly against the U.S dollar in 2014, which resulted in $0.5 million and $0.4 million in increased foreign exchange losses during the three and nine months of 2014.


Provision for Income Taxes

We recorded an income tax provision of $0.2 million and $0.5 million for the three and nine months ended September 30, 2015, and $0.2 million and $0.7 million for the three and nine months ended September 30, 2014, which was primarily due to state and foreign taxes. We maintain a valuation allowance on federal and state deferred tax assets as we do not believe it is more likely than not that said deferred tax assets will be realized. We will continue to maintain a full valuation allowance on our deferred tax assets until there is sufficient evidence to support the reversal of all or some portion of this allowance.


Liquidity and Capital Resources

As of September 30, 2015, we had cash and cash equivalents of $100.5 million, including $2.3 million held outside the United States in our foreign subsidiaries. We currently do not have any plans to repatriate our earnings from our foreign operations. As of September 30, 2015, we had working capital of $91.0 million, accumulated deficit of $214.5 million and total stockholders' equity of $80.9 million.

We plan to continue to invest for long-term growth and anticipate our investment will continue to increase in absolute dollars. We believe that our existing cash and cash equivalents and other available financial resources will be sufficient to meet our anticipated cash needs for at least the next 12 months. Our future capital requirements will depend on many factors, including our growth rate, the expansion of sales and marketing activities, the timing and extent of spending to support development efforts, the introduction of new and enhanced product and service offerings and the continuing market acceptance of our products. In the event that additional financing is required from outside sources, we may not be able to raise such financing on terms acceptable to us or at all. If we are unable to raise additional capital when desired, our business, operating results and financial condition could be adversely affected.

In addition, as described in Note 5. Commitments and Contingencies, we are currently involved in ongoing litigation. Any adverse settlements or judgments in any litigation could have a material adverse impact on our results of operations, cash balances and cash flows in the period in which such events occur.

Credit Agreement

In September 2013, we entered into a credit agreement with Royal Bank of Canada, acting as administrative agent and lender, and JPMorgan Chase Bank, N.A. and Bank of America, N.A. as lenders. The credit agreement provides a three-year $35.0 million revolving credit facility, which includes a maximum $10.0 million letter of credit facility. The revolving credit facility expires on September 30, 2016.

Our obligations under the credit agreement are secured by a security interest on substantially all of our assets, including our intellectual property. The credit agreement contains customary non-financial covenants, and also requires us to comply with financial covenants. One financial covenant requires us to maintain a total leverage ratio, which is defined as total consolidated debt divided by adjusted EBITDA (defined as earnings before interest expense, tax expense, depreciation, amortization and stock-based compensation, adjusted for certain other non-cash or non-recurring income or expenses such as specified litigation settlement payments and litigation expenses) for the trailing four quarters. In addition, we must maintain a minimum amount of liquidity based on our unrestricted cash and availability under the revolving credit facility. The covenant requires us to maintain a minimum liquidity of $25.0 million provided that at least $10.0 million of such liquidity is comprised of unrestricted cash and cash equivalents. The credit agreement includes customary events of default which, if triggered, could result in the acceleration of our obligations under the revolving credit facility, the termination of any obligation by the lenders to extend further credit and the right of the lenders to exercise their remedies as a secured creditor and foreclose upon the collateral securing our obligation under the credit agreement; however, we also have the ability, in certain instances, to cure

26


non-compliance with the financial covenants through qualified equity contributions by certain holders of our equity. Currently, the agreement for our revolving credit facility contains restrictions on our ability to pay dividends. As of September 30, 2015, we had no outstanding balance on our credit facility and were in compliance with our covenants.

Cash Flows from Operating Activities

Our cash used in operating activities is driven primarily by sales of our products and, to a lesser extent, by up-front payments from end-customers under PCS contracts. Our primary uses of cash from operating activities have been for personnel-related expenditures, manufacturing costs, marketing and promotional expenses, costs related to our facilities and litigation expenses. Our cash flows from operating activities will continue to be affected principally by the extent to which we increase spending on personnel and sales and marketing activities, our working capital requirements, and litigation expenses.

During the nine months ended September 30, 2015, cash provided by operating activities was $7.6 million, consisting of a net loss of $32.7 million partially offset by non-cash charges of $21.6 million and an $18.7 million cash increase that resulted from changes in net operating assets and liabilities. Our non-cash charges consisted of $13.2 million of stock-based compensation, $6.8 million of depreciation and amortization and $1.6 million in provision for doubtful accounts and sales returns allowance. The changes in our net operating assets and liabilities were primarily attributable to an $11.2 million decrease in accounts receivable, a $9.1 million increase in deferred revenue, and a $0.9 million decrease in inventory, partially offset by a $2.6 million decrease in accounts payable and accrued liabilities.

The decrease in accounts receivable was primarily due to improved cash collection in 2015 and the timing of billing, as a higher portion of the December 31, 2014 outstanding accounts receivable were billed during the latter part of the quarter compared to the September 30, 2015 outstanding accounts receivable. The increase in deferred revenue was due to timing of billings of support contracts, the increase in PCS sales in connection with our increasing installed customer base and an increase in deferred professional services revenue. The decrease in inventory was primarily due to increased consumption of existing inventory. The decrease in accounts payable and accrued liabilities was primarily attributable to a decrease in accrued compensation costs largely due to the payment of accrued commissions and bonuses and the timing of vendor invoice payments.
During the nine months ended September 30, 2014, cash used in operating activities was $13.5 million, consisting of a net loss of $18.7 million and a $3.5 million increase in net operating assets and liabilities offset by non-cash charges of $8.7 million. Our non-cash charges consisted primarily of stock-based compensation of $8.3 million and depreciation and amortization of $7.3 million, partially offset by a $7.0 million gain on settlement of a contractual liability. The change in our net operating assets and liabilities was primarily due to a $6.8 million decrease in accrued litigation expenses, a $6.3 million increase in inventory, a $4.8 million increase in accounts receivable and a $3.3 million increase in prepaid expenses and other current assets, partially offset by a $9.7 million increase in deferred revenue and an $8.2 million increase in accounts payable and accrued liabilities.
The decrease in accrued litigation costs was primarily due to the $5.0 million payment we made under the terms of a settlement of a contractual liability we reached with one of our legal services providers in May 2014 as well as lower litigation activities in the nine months ended September 30, 2014 compared to the same period in 2013. The increase in inventory and prepaid and other current assets was attributable to our year over year business growth. The increase in accounts receivable was primarily due to increased billing and the timing of billing and cash collection, as a higher portion of the September 30, 2014 outstanding accounts receivable were billed during the latter part of the quarter compared to the December 31, 2013 outstanding accounts receivable. The increase in accounts payable and accrued liabilities was primarily attributable to increases in accrued compensation costs due to higher headcount and increases in accounts payable and other accrued liabilities

27


as a result of increased business activity levels and the timing of vendor invoice payments. The increase in deferred revenue was due to billings of support contracts with service terms that are typically one year.

Cash Flows from Investing Activities

During the nine months ended September 30, 2015 and 2014, cash used in investing activities was $2.6 million and $5.4 million, primarily for purchases of property and equipment. 

Cash Flows from Financing Activities

During the nine months ended September 30, 2015, cash provided by financing activities was $3.5 million, consisting of proceeds from common stock issuance under our equity incentive plans, net of repurchases of common stock.
During the nine months ended September 30, 2014, cash provided by financing activities was $105.2 million, primarily consisting of $121.0 million in net proceeds from the issuance of our common stock to outside investors in our IPO, and $4.4 million from the exercise of common stock options, net of repurchases of common stock, partially offset by a $20.0 million repayment of our revolving credit facility.

Contractual Obligations

In September 2013, we entered into a credit agreement with Royal Bank of Canada, JPMorgan Chase Bank, N.A. and Bank of America, N.A. as lenders. The credit agreement provides a three-year $35.0 million revolving credit facility, which includes a maximum $10.0 million letter of credit facility. We have no outstanding borrowings under this credit facility as of September 30, 2015.

Off-Balance Sheet Arrangements

As of September 30, 2015, we did not have any relationships with any unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities that would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes.

Critical Accounting Policies and Estimates

Our condensed consolidated financial statements are prepared in accordance with U.S. GAAP. The preparation of these condensed consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, expenses and related disclosures. We evaluate our estimates and assumptions on an ongoing basis. Our estimates are based on historical experience and various other assumptions that we believe to be reasonable under the circumstances. Our actual results could differ from these estimates.


There were no significant changes in our critical accounting policies and estimates during the nine months ended September 30, 2015 as compared to the critical accounting policies and estimates disclosed in Management’s Discussion and Analysis of Financial Condition and Results of Operations included in our annual report on Form 10-K filed with the SEC on March 11, 2015. 

ITEM 3.
QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Foreign Currency Risk

Our consolidated results of operations, financial position and cash flows are subject to fluctuations due to changes in foreign currency exchange rates. Historically, the majority of our revenue contracts are denominated in U.S. dollars, with the most significant exception being Japan where we invoice primarily in the Japanese yen. Our costs and expenses are generally denominated in the currencies where our operations are located, which is primarily in North America, Japan and to a lesser extent EMEA and the Asia Pacific region. To date, we have not entered into any hedging arrangements with respect to foreign currency risk or other derivative instruments. Revenue resulting from selling in local currencies and costs and expenses incurred in local currencies are exposed to foreign currency exchange rate fluctuations which can affect our revenue and operating income. As exchange rates vary, operating income may differ from expectations.


28


The functional currency of our foreign subsidiaries is the U.S. dollar. At the end of each reporting period, monetary assets and liabilities are remeasured to the functional currency using exchange rates in effect at the balance sheet date. Nonmonetary assets and liabilities are remeasured at historical exchange rates. Gains and losses related to remeasurement are recorded in interest income and other income (expense), net in the Consolidated Statements of Operations. A significant fluctuation in the exchange rates between our subsidiaries' local currencies, especially the Japanese yen and the Euro, and the U.S. dollar could have an adverse impact on our consolidated financial position and results of operations.

We recorded $0.3 million and $0.7 million foreign exchange loss during the nine months ended September 30, 2015 and 2014. The effect of a hypothetical 10% change in our exchange rate would not have a significant impact on our consolidated results of operations.

We do not yet have any hedging programs in place to limit the risk of exchange rate fluctuation. In the future, however, to the extent our foreign currency exposures become more material, we may elect to deploy normal and customary hedging practices designed to more proactively mitigate such exposure.

Interest Rate Sensitivity

Our exposure to market risk for changes in interest rates relates primarily to our cash and cash equivalents and our indebtedness. Our cash and cash equivalents are held in cash deposits and money market funds with maturities of less than 90 days from the date of purchase. Our primary exposure to market risk is interest income sensitivity, which is affected by changes in the general level of the interest rates in the United States. However, because of the short-term nature of the instruments in our portfolio, a sudden change in market interest rates would not be expected to have a material impact on our consolidated financial statements.

Our exposure to interest rate risk relates to our revolving credit facility with variable interest rates, where an increase in interest rates may result in higher borrowing costs. Since we have no outstanding borrowings under our credit facility as of September 30, 2015, the effect of a hypothetical 10% change in interest rates would not have a significant impact on our interest expense.
 
ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures, as required by Rule 13a-15(b) under the Securities Exchange Act of 1934 as amended (the “Exchange Act”), as of September 30, 2015. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were not effective as of September 30, 2015 solely due to the material weakness in our internal control over financial reporting as described below.

Changes in Internal Control over Financial Reporting

Through September 30, 2015, our management, with the participation of our Chief Executive Officer and Chief Financial Officer, have evaluated whether there were any changes in our internal control over financial reporting since December 31, 2014. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that no changes in our internal control over financial reporting occurred during the three months ended September 30, 2015 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting, except as described below with regards to computation of stock-based compensation related to our 2014 Purchase Plan.

As discussed in Item 9A. Controls and Procedures in our Annual Report on Form 10-K for the year ended December 31, 2014, management identified a material weakness in our internal control over financial reporting as it relates to the computation of stock-based compensation associated with our 2014 Purchase Plan.

In response to the material weakness described above, during the three months ended September 30, 2015, we continued to evaluate new controls and procedures. Though management is still evaluating the effectiveness of these new procedures, we believe that our improved processes and procedures will lead to the remediation of the material weakness by the end of 2015. Once placed in operation for a sufficient period of time, we will subject these procedures to appropriate tests, in order to determine whether they are operating effectively. In designing and evaluating the stock-based compensation controls

29


and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives.

Management has implemented the following steps during the first nine months of 2015:

We added a control activity where we will consult with technical accounting experts to review and analyze the impact of new or unusual accounting transactions and the adoption of new accounting standards that may have a material impact on our consolidated financial statements.

We strengthened our processes in the area of equity administration and equity accounting, which included the review, redesign and documentation of our policies and procedures; implementation of additional review and reconciliation controls, and expanded the use of software based solutions to handle certain aspects of accounting for stock-based compensation related to the 2014 Purchase Plan.

We will continue to evaluate the effectiveness of our internal controls and procedures on an ongoing basis and will take further action, as appropriate.

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

We have been and may currently be involved in various legal proceedings, the outcomes of which are not within our complete control or may not be known for prolonged periods of time. Management is required to assess the probability of loss and amount of such loss, if any, in preparing our consolidated financial statements. We evaluate the likelihood of a potential loss from legal proceedings to which we are a party. We record a liability for such claims when a loss is deemed probable and the amount can be reasonably estimated. Significant judgment may be required in the determination of both probability and whether an exposure is reasonably estimable. Our judgments are subjective based on the status of the legal proceedings, the merits of our defenses and consultation with in-house and outside legal counsel. As additional information becomes available, we reassess the potential liability related to pending claims and may revise our estimates. Due to the inherent uncertainties of the legal processes in the multiple jurisdictions in which we operate, our judgments may be materially different than the actual outcomes, which could have material adverse effects on our business, financial conditions and results of operations.

Additional information with respect to this Item may be found in Note 5. Commitments and Contingencies, in the Notes to Condensed Consolidated Financial Statements of this Quarterly Report on Form 10-Q, which is incorporated into this Item 1 by reference.

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 contained in this report, and in our other public filings. The risks and uncertainties described below are not the only ones we face. Additional risks and uncertainties that we are unaware of, or that we currently believe are not material, may also become important factors that affect us. If any of the following risks occur, our business, financial condition, operating results, and prospects could be materially harmed. In that event, the trading price of our common stock could decline, perhaps significantly.

If we do not successfully anticipate market needs and opportunities or if the market does not continue to adopt our application networking products, our business, financial condition and results of operations could be significantly harmed.

The application networking market is rapidly evolving and difficult to predict. Technologies, customer requirements, security threats and industry standards are constantly changing. As a result, we must anticipate future market needs and opportunities and then develop new products or enhancements to our current products that are designed to address those needs and opportunities, and we may not be successful in doing so. 

Even if we are able to anticipate, develop and commercially introduce new products and enhancements that address the market’s needs and opportunities, there can be no assurance that new products or enhancements will achieve widespread market acceptance. For example, organizations that use other conventional or first-generation application networking products for their needs may believe that these products are sufficient. In addition, as we launch new product offerings, organizations

30


may not believe that such new product offerings offer any additional benefits as compared to the existing application networking products that they currently use. Accordingly, organizations may continue allocating their IT budgets for existing application networking products and may not adopt our products, regardless of whether our products can offer superior performance or security. 

If we fail to anticipate market needs and opportunities or if the market does not continue to adopt our application networking products, then market acceptance and sales of our current and future application networking products could be substantially decreased or delayed, we could lose customers, and our revenue may not grow or may decline. Any of such events would significantly harm our business, financial condition and results of operations.

Our success depends on our timely development of new products and features to address rapid technological changes and evolving customer requirements. If we are unable to timely develop new products and features that adequately address these changes and requirements, our business and operating results could be adversely affected.

Changes in application software technologies, data center and communications hardware, networking software and operating systems, and industry standards, as well as our end-customers’ continuing business growth, result in evolving application networking needs and requirements. Our continued success depends on our ability to identify and develop in a timely manner new products and new features for our existing products that meet these needs and requirements.

Our future plans include significant investments in research and development and related product opportunities. Developing our products and related enhancements is time-consuming and expensive. We have made significant investments in our research and development team in order to address these product development needs. Our investments in research and development may not result in significant design and performance improvements or marketable products or features, or may result in products that are more expensive than anticipated. We may take longer to generate revenue, or generate less revenue, than we anticipate from our new products and product enhancements. We believe that we must continue to dedicate a significant amount of resources to our research and development efforts to maintain our competitive position.

If we are unable to develop new products and features to address technological changes and new customer requirements in the application networking market or if our investments in research and development do not yield the expected benefits in a timely manner, our business and operating results could be adversely affected.

We have experienced net losses in recent periods, anticipate increasing our operating expenses in the future and may not achieve or maintain profitability in the future. If we cannot achieve or maintain profitability, our financial performance will be harmed and our business may suffer.

We experienced net losses for the years ended December 31, 2013 and 2014, and nine months ended September 30, 2015. Although we experienced revenue growth over these same periods and had achieved profitability in prior year periods, we may not be able to sustain or increase our revenue growth or achieve profitability in the future or on a consistent basis. During 2013 and 2014, we invested in our sales, marketing and research and development teams in order to develop, market and sell our products. We expect to continue to invest significantly in these areas in the future. As a result of these increased expenditures, we will have to generate and sustain increased revenue, manage our cost structure and avoid significant liabilities to achieve future profitability. In particular, in 2012 and 2013, we incurred substantial expenses associated with defending ourselves in separate litigation matters involving Brocade Communications Systems, Inc. and Radware Ltd. (both settled) and in our settlement of the Brocade litigation. As a public company, we are also incurring significant accounting, legal and other expenses that we did not incur as a private company.

Revenue growth may slow or decline, and we may incur significant losses in the future for a number of possible reasons, including our inability to develop products that achieve market acceptance, general economic conditions, increasing competition, decreased growth in the markets in which we operate, or our failure for any reason to capitalize on growth opportunities. Additionally, we may encounter unforeseen operating expenses, difficulties, complications, delays and other unknown factors that may result in losses in future periods. If these losses exceed our expectations or our revenue growth expectations are not met in future periods, our financial performance will be harmed and our stock price could be volatile or decline.

Our operating results are likely to vary significantly from period to period and may be unpredictable, which could cause the trading price of our common stock to decline.

Our operating results, in particular, revenue, margins and operating expenses, have fluctuated in the past, and we expect this will continue, which makes it difficult for us to predict our future operating results. The timing and size of sales of our products are highly variable and difficult to predict and can result in significant fluctuations in our revenue from period to period. This is particularly true of sales to our largest end-customers, such as service providers, Web giants and governmental organizations, who typically make large and concentrated purchases and for whom close or sales cycles can be long, as a result of their complex networks and data centers, as well as requests that may be made for customized features. Our quarterly results may vary significantly based on when these large end-customers place orders with us and the content of their orders. For example, during the three months ended September 30, 2014, we experienced a decline in our revenues primarily due to longer than expected close or sales cycles for certain large deals and lower North America service provider spending as compared to the same period in 2013, which may have contributed to a dramatic decline in our stock price. We anticipate a possible slowdown in spending from North America service providers, which may lead to continued near term fluctuation in our product revenue and total revenue.

 Our operating results may also fluctuate due to a number of other factors, many of which are outside of our control and may be difficult to predict. In addition to other risks listed in this “Risk Factors” section, factors that may affect our operating results include:

fluctuations in and timing of purchases from, or loss of, large customers;

the budgeting cycles and purchasing practices of end-customers;

our ability to attract and retain new end-customers;

changes in demand for our products and services, including seasonal variations in customer spending patterns or cyclical fluctuations in our markets;

our reliance on shipments at the end of our quarters;

variations in product mix or geographic locations of our sales, which can affect the revenue we realize for those sales;

the timing and success of new product and service introductions by us or our competitors;

our ability to increase the size of our distribution channel and to maintain relationships with important distribution channel partners;

the effect of currency exchange rates on our revenue and expenses;

the cost and potential outcomes of existing and future litigation;

the effect of discounts negotiated by our largest end-customers for sales or pricing pressure from our competitors;

changes in the growth rate of the application networking market or changes in market needs;

inventory write downs, which may be necessary for our older products when our new products are launched and adopted by our end-customers; and

our third-party manufacturers’ and component suppliers’ capacity to meet our product demand forecasts on a timely basis, or at all.

Any one of the factors above or the cumulative effect of some of these factors may result in significant fluctuations in our financial and other operating results. This variability and unpredictability could result in our failure to meet our or our investors’ or securities analysts’ revenue, margin or other operating results expectations for a particular period, resulting in a decline in the trading price of our common stock.

32



Reliance on shipments at the end of the quarter could cause our revenue for the applicable period to fall below expected levels.

As a result of end-customer buying patterns and the efforts of our sales force and distribution channel partners to meet or exceed their sales objectives, we have historically received a substantial portion of purchase orders and generated a substantial portion of revenue during the last few weeks of each quarter. We can recognize such revenue in the quarter received, however, only if all of the requirements of revenue recognition, especially shipment, are met by the end of the quarter. In addition, any significant interruption in our information technology systems, which manage critical functions such as order processing, revenue recognition, financial forecasts, inventory and supply chain management, could result in delayed order fulfillment and thus decreased revenue for that quarter. If expected revenue at the end of any quarter is delayed for any reason, including the failure of anticipated purchase orders to materialize, our third-party manufacturers’ inability to manufacture and ship products prior to quarter-end to fulfill purchase orders received near the end of the quarter, our failure to manage inventory to meet demand, our inability to release new products on schedule, any failure of our systems related to order review and processing, or any delays in shipments or achieving specified acceptance criteria, our revenue for that quarter could fall below our, or our investors’ or securities analysts’ expectations, resulting in a decline in the trading price of our common stock.

A limited number of our end-customers, including service providers, make large and concentrated purchases that comprise a significant portion of our revenue. Any loss or delay of expected purchases by our largest end-customers could adversely affect our operating results.

As a result of the nature of our target market and the current stage of our development, a substantial portion of our revenue in any period comes from a limited number of large end-customers, including service providers. For example, NTT DoCoMo, Inc., through a reseller, accounted for approximately 32% of our total revenue during 2012, approximately 13% of our total revenue during 2013 and 7% of our total revenue during 2014.  In addition, during the years ended December 31, 2013 and 2014, and the nine months ended September 30, 2015, purchases from our ten largest end-customers accounted for approximately 43% , 37% and 30% of our total revenue. The composition of the group of these ten largest end-customers changes from period to period, but often includes service providers, who accounted for approximately 47%, 46% and 42% of our total revenue during the years ended December 31, 2013 and 2014, and nine months ended September 30, 2015.

Sales to these large end-customers have typically been characterized by large but irregular purchases with long initial sales cycles. After initial deployment, subsequent purchases of our products typically have a more compressed sales cycle. The timing of these purchases and of the requested delivery of the purchased product is difficult to predict. As a consequence, any acceleration or delay in anticipated product purchases by or requested deliveries to our largest end-customers could materially affect our revenue and operating results in any quarter and cause our quarterly revenue and operating results to fluctuate from quarter to quarter.

We cannot provide any assurance that we will be able to sustain or increase our revenue from our largest end-customers nor that we will be able to offset any absence of significant purchases by our largest end-customers in any particular period with purchases by new or existing end-customers in that or a subsequent period. We expect that sales of our products to a limited number of end-customers will continue to contribute materially to our revenue for the foreseeable future. The loss of, or a significant delay or reduction in purchases by, a small number of end-customers could have a material adverse effect on our consolidated financial position, results of operations or cash flows.

We have been and are, or may in the future be, a party to litigation and claims regarding intellectual property rights, resolution of which has been and may in the future be time-consuming, expensive and adverse to us, as well as require a significant amount of resources to prosecute, defend, or make our products non-infringing.

Our industry is characterized by the existence of a large number of patents and by increasingly frequent claims and related litigation based on allegations of infringement or other violations of patent and other intellectual property rights. In the ordinary course of our business, we have been and are involved in disputes and licensing discussions with others regarding their patents and other claimed intellectual property and proprietary rights. Intellectual property infringement and misappropriation lawsuits and other claims are subject to inherent uncertainties due to the complexity of the technical and legal issues involved, and we cannot be certain that we will be successful in defending ourselves against such claims or in concluding licenses on reasonable terms or at all.

We currently have fewer issued patents than some of our major competitors, and therefore may not be able to utilize our patent portfolio effectively to assert defenses or counterclaims in response to patent infringement claims or litigation brought against us by third parties. Further, litigation may involve patent holding companies or other adverse patent owners that

33


have no relevant product revenue and against which our potential patents may provide little or no deterrence. In addition, many potential litigants have the capability to dedicate substantially greater resources than we can to enforce their intellectual property rights and to defend claims that may be brought against them. We expect that infringement claims may increase as the numbers of product types and the number of competitors in our market increases. Also, to the extent we gain greater visibility, market exposure and competitive success, we face a higher risk of being the subject of intellectual property infringement claims.

If we are found in the future to infringe the proprietary rights of others, or if we otherwise settle such claims, we could be compelled to pay damages or royalties and either obtain a license to those intellectual property rights or alter our products such that they no longer infringe. Any license could be very expensive to obtain or may not be available at all. Similarly, changing our products or processes to avoid infringing the rights of others may be costly, time-consuming or impractical. Alternatively, we could also become subject to an injunction or other court order that could prevent us from offering our products. Any of these claims, regardless of their merit, may be time-consuming, result in costly litigation and diversion of technical and management personnel, or require us to cease using infringing technology, develop non-infringing technology or enter into royalty or licensing agreements.

Many of our commercial agreements require us to indemnify our end-customers, distributors and resellers for certain third-party intellectual property infringement actions related to our technology, which may require us to defend or otherwise become involved in such infringement claims, and we could incur liabilities in excess of the amounts we have received for the relevant products and/or services from our end-customers, distributors or resellers. These types of claims could harm our relationships with our end-customers, distributors and resellers, may deter future end-customers from purchasing our products or could expose us to litigation for these claims. Even if we are not a party to any litigation between an end-customer, distributor or reseller, on the one hand, and a third party, on the other hand, an adverse outcome in any such litigation could make it more difficult for us to defend our intellectual property rights in any subsequent litigation in which we are a named party.

We have in the past been involved in intellectual property litigation matters with F5 Networks, Inc., Allegro Software Development, Inc., Brocade, Radware and Parallel Networks, LLC., all of which have since settled. As part of the settlement with Brocade, we made a significant cash payment to Brocade, granted a license to Brocade to use all of our issued, pending and future patents, and received and granted certain covenants not to sue.

We may face risks related to shareholder litigation that could result in significant legal expenses and settlement or damage awards.

We are currently and may in the future become subject to claims and litigation alleging violations of securities laws or other related claims, including shareholder derivative litigation, which could harm our business, divert management attention and require us to incur significant costs. For example, in January 2015, a class action lawsuit was filed against us, our Board of Directors, our Chief Financial Officer and the underwriters of our initial public offering alleging violations of the Securities Act of 1933. Several substantially identical lawsuits were subsequently filed in the same court, bringing the same claims against the same defendants. A related shareholder derivatives action was filed in January 2015. These lawsuits seek unspecified compensatory damages and other relief. We are generally obliged, to the extent permitted by law, to indemnify our current and former directors and officers who are named as defendants in these types of lawsuits. We also have certain contractual obligations to the underwriters regarding the securites class action lawsuits. While a certain amount of insurance coverage is available for expenses or losses associated with these lawsuits, this coverage may not be sufficient. Based on information currently available, we are unable to reasonably estimate a possible loss or range of possible loss, if any, with regards to these lawsuits; therefore, no litigation reserve has been recorded in the accompanying Condensed Consolidated Balance Sheets. Although we plan to defend against these lawsuits vigorously, there can be no assurances that a favorable final outcome will be obtained. These lawsuits or future litigation may require significant attention from management and could result in significant legal expenses, settlement costs or damage awards that could have a material impact on our financial position, results of operations and cash flows.



34


We may not be able to adequately protect our intellectual property, and if we are unable to do so, our competitive position could be harmed, or we could be required to incur significant expenses to enforce our rights.

We rely on a combination of patent, copyright, trademark and trade secret laws, and contractual restrictions on disclosure of confidential and proprietary information, to protect our intellectual property. Despite the efforts we take to protect our intellectual property and other proprietary rights, these efforts may not be sufficient or effective at preventing their unauthorized use. In addition, effective trademark, patent, copyright and trade secret protection may not be available or cost-effective in every country in which we have rights. There may be instances where we are not able to protect intellectual property or other proprietary rights in a manner that maximizes competitive advantage. If we are unable to protect our intellectual property and other proprietary rights from unauthorized use, the value of those assets may be reduced, which could negatively impact our business.

We also rely in part on confidentiality and/or assignment agreements with our technology partners, employees, consultants, advisors and others. These protections and agreements may not effectively prevent disclosure of our confidential information and may not provide an adequate remedy in the event of unauthorized disclosure. In addition, others may independently discover our trade secrets and intellectual property information we thought to be proprietary, and in these cases we would not be able to assert any trade secret rights against those parties. Despite our efforts to protect our intellectual property, unauthorized parties may attempt to copy or otherwise obtain and use our intellectual property or technology. Monitoring unauthorized use of our intellectual property is difficult and expensive. We have not made such monitoring a priority to date and will not likely make this a priority in the future. We cannot be certain that the steps we have taken or will take will prevent misappropriation of our technology, particularly in foreign countries where the laws may not protect our proprietary rights as fully as in the United States.

If we fail to protect our intellectual property adequately, our competitors might gain access to our technology, and our business might be harmed. In addition, even if we protect our intellectual property, we may need to license it to competitors, which could also be harmful. For example, we have already licensed all of our issued patents, pending applications, and future patents and patent applications that we may acquire, obtain, apply for or have a right to license to Brocade until May 2025, for the life of each such patent. In addition, we might incur significant expenses in defending our intellectual property rights. Any of our patents, copyrights, trademarks or other intellectual property rights could be challenged by others or invalidated through administrative process or litigation.

We may in the future initiate claims or litigation against third parties for infringement of our proprietary rights or to establish the validity of our proprietary rights. Any litigation, whether or not resolved in our favor, could result in significant expense to us and divert the efforts of our management and technical personnel, as well as cause other claims to be made against us, which might adversely affect our business, operating results and financial condition.

We face intense competition in our market, especially from larger, well-established companies, and we may lack sufficient financial or other resources to maintain or improve our competitive position.

The application networking market is intensely competitive, and we expect competition to increase in the future. To the extent that we sell our solutions in adjacent markets, we expect to face intense competition in those markets as well. We believe that our main competitors fall into three categories:

Companies that sell products in the traditional ADC market. In the ADC market, we compete against other companies that are well established in this market, including F5 Networks, Inc., Brocade, Cisco Systems, Inc., Citrix Systems, Inc., and Radware Ltd.;

Companies that sell CGN products. Our purpose-built CGN solution competes primarily against products originally designed for other networking purposes, such as edge routers and security appliances from vendors such as Alcatel-Lucent USA Inc., Cisco Systems, Inc. and Juniper Networks, Inc.; and

Companies that sell traditional DDoS mitigation products. We are a new entrant into the DDoS market and first publicly launched our DDoS detection and mitigation solution, TPS, in January 2014. We believe our principal competitors in this market are Arbor Networks, Inc., a subsidiary of Danaher Corporation, and Radware.

Many of our competitors are substantially larger and have greater financial, technical, research and development, sales and marketing, manufacturing, distribution and other resources and greater name recognition. In addition, some of our larger competitors have broader products offerings and could leverage their customer relationships based on their other products.

35


Potential customers who have purchased products from our competitors in the past may also prefer to continue to purchase from these competitors rather than change to a new supplier regardless of the performance, price or features of the respective products. We could also face competition from new market entrants, which may include our current technology partners. As we continue to expand globally, we may also see new competitors in different geographic regions. Such current and potential competitors may also establish cooperative relationships among themselves or with third parties that may further enhance their resources.

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 and services at a greater range of prices;

the ability to 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;

broader distribution and established relationships with distribution channel partners in a greater number of worldwide locations;

access to larger end-customer bases;

the ability to use their greater financial resources to attract our research and development engineers as well as other employees of ours;

larger intellectual property portfolios; and

the ability to bundle competitive offerings with other products and services.

Our ability to compete will depend upon our ability to provide a better solution than our competitors at a competitive price. We may be required to make substantial additional investments in research and 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. Moreover, 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. As a result of these acquisitions, our current or potential competitors might take advantage of the greater resources of the larger organization to compete more vigorously or broadly with us. In addition, continued industry consolidation might adversely impact end-customers’ perceptions of the viability of smaller and even medium-sized networking companies and, consequently, end-customers’ willingness to purchase from companies like us.

As a result, increased competition could lead to fewer end-customer orders, price reductions, reduced margins and loss of market share.

Some of our large end-customers demand favorable terms and conditions from their vendors and may request price concessions. As we seek to sell more products to these end-customers, we may agree to terms and conditions that may have an adverse effect on our business.

Some of our large end-customers have significant purchasing power and, accordingly, have requested from us and received more favorable terms and conditions, including lower prices than we typically provide. As we seek to sell products to this class of end-customer, we may agree to these terms and conditions, which may include terms that reduce our gross margin and have an adverse effect on our business.


36


If we are unable to attract new end-customers, sell additional products to our existing end-customers or achieve the anticipated benefits from our investment in additional sales personnel and resources, our revenue may decline, and our gross margin will be adversely affected.

To maintain and increase our revenue, we must continually add new end-customers and sell additional products to existing end-customers. The rate at which new and existing end-customers purchase solutions depends on a number of factors, including some outside of our control, such as general economic conditions. If our efforts to sell our solutions to new end-customers and additional solutions to our existing end-customers are not successful, our business and operating results will suffer.

In recent periods, we have been adding personnel and other resources to our sales and marketing functions, as we focus on growing our business, entering new markets and increasing our market share. We expect to incur significant additional expenses by hiring additional sales personnel and expanding our international operations in order to seek revenue growth. The return on these and future investments may be lower, or may be realized more slowly, than we expect, if realized at all. If we do not achieve the benefits anticipated from these investments, or if the achievement of these benefits is delayed, our growth rates will decline, and our gross margin would likely be adversely affected.

Our gross margin may fluctuate from period to period based on the mix of products sold, the geographic location of our customers, price discounts offered, required inventory write downs and current exchange rate fluctuations.

Our gross margin may fluctuate from period to period in response to a number of factors, such as the mix of our products sold and the geographic locations of our sales. Our products tend to have varying gross margins in different geographic regions. We also may offer pricing discounts from time to time as part of a targeted sales campaign or as a result of pricing pressure from our competitors. In addition, our larger end-customers may negotiate pricing discounts in connection with large orders they place with us. The sale of our products at discounted prices could have a negative impact on our gross margin. We also must manage our inventory of existing products when we introduce new products. For example, in the fourth quarter of 2013 and the third quarter of 2014, our gross margin decreased to 74% and 73% due primarily to geographical mix and selling some end-of-life product at low margins.

If we are unable to sell the remaining inventory of our older products prior to or following the launch of such new product offerings, we may be forced to write down inventory for such older products, which could also negatively affect our gross margin. Our gross margin may also vary based on international currency exchange rates. In general, our sales are denominated in U.S. dollars; however, in Japan they are denominated in Japanese yen. Changes in the exchange rate between the U.S. dollar and the Japanese yen may therefore affect our actual revenue and gross margin. For example, in the third and fourth quarters of 2014, our gross margin was adversely impacted by both an increase in our inventory reserve primarily due to obsolete inventory on hand and unfavorable exchange rate fluctuations between the U.S. dollar and the Japanese yen. We anticipate that our gross margin will continue to be impacted by these factors in subsequent periods.

We generate a significant amount of revenue from sales to distributors, resellers, and end-customers outside of the United States, and we are therefore subject to a number of risks that could adversely affect these international sources of our revenue.

A significant portion of our revenue is generated in international markets, including Japan, Western Europe, China, Taiwan and South Korea. For the years ended December 31, 2013 and 2014, and the nine months ended September 30, 2015 approximately 52%, 52% and 47% of our total revenue was generated from customers located outside of the United States. If we are unable to maintain or continue to grow our revenue in these markets, our financial results may suffer.

As a result, we must hire and train experienced personnel to staff and manage our foreign operations. To the extent that we experience difficulties in recruiting, training, managing and retaining an international staff, and specifically sales management and sales personnel, we may experience difficulties in sales productivity in foreign markets. We also seek to enter into distributor and reseller relationships with companies in certain international markets where we do not have a local presence. If we are not able to maintain successful distributor relationships internationally or recruit additional companies to enter into distributor relationships, our future success in these international markets could be limited. Business practices in the international markets that we serve may differ from those in the United States and may require us in the future to include terms in customer contracts other than our standard terms. To the extent that we may enter into customer contracts in the future that include non-standard terms, our operating results may be adversely impacted.


37


We have a significant presence in international markets and plan to continue to expand our international operations, which exposes us to a number of risks that could affect our future growth.

Our sales team is comprised of field sales and inside sales personnel who are organized by geography and maintain sales presence in 28 countries, including in the following countries and regions: United States, Western Europe, Japan, China, Taiwan and South Korea. We expect to continue to increase our sales headcount in all markets, particularly in markets where we currently do not have a sales presence. As we continue to expand our international sales and operations, we are subject to a number of risks, including the following:

greater difficulty in enforcing contracts and accounts receivable collection and longer collection periods;

increased expenses incurred in establishing and maintaining office space and equipment for our international operations;

greater difficulty in recruiting local experienced personnel, and the costs and expenses associated with such activities;

general economic and political conditions in these foreign markets;

economic uncertainty around the world, including continued economic uncertainty as a result of sovereign debt issues in Europe;

management communication and integration problems resulting from cultural and geographic dispersion;

risks associated with trade restrictions and foreign legal requirements, including the importation, certification, and localization of our products required in foreign countries;

greater risk of unexpected changes in regulatory practices, tariffs, and tax laws and treaties;

the uncertainty of protection for intellectual property rights in some countries;

greater risk of a failure of foreign employees to comply with both U.S. and foreign laws, including antitrust regulations, the U.S. Foreign Corrupt Practices Act, and any trade regulations ensuring fair trade practices; and

heightened risk of unfair or corrupt business practices in certain geographies and of improper or fraudulent sales arrangements that may impact financial results and result in restatements of, or irregularities in, financial statements.

Because of our worldwide operations, we are also subject to risks associated with compliance with applicable anticorruption laws. One such applicable anticorruption law is the U.S. Foreign Corrupt Practices Act, or FCPA, which generally prohibits U.S. companies and their employees and intermediaries from making payments to foreign officials for the purpose of obtaining or keeping business, securing an advantage, or directing business to another, and requires public companies to maintain accurate books and records and a system of internal accounting controls. Under the FCPA, U.S. companies may be held liable for actions taken by directors, officers, employees, agents, or other strategic or local partners or representatives. As such, if we or our intermediaries, such as channel partners and distributors, fail to comply with the requirements of the FCPA or similar legislation, governmental authorities in the United States and elsewhere could seek to impose civil and/or criminal fines and penalties which could have a material adverse effect on our business, operating results and financial condition.

We are exposed to fluctuations in currency exchange rates, which could negatively affect our results of operations.

Our consolidated results of operations, financial position and cash flows are subject to fluctuations due to changes in foreign currency exchange rates. Historically, the majority of our revenue contracts are denominated in U.S. dollars, with the most significant exception being Japan, where we invoice primarily in the Japanese yen. Our expenses are generally denominated in the currencies in which our operations are located, which is primarily in North America and Japan. Revenue resulting from selling in local currencies and costs incurred in local currencies are exposed to foreign currency exchange rate fluctuations that can affect our operating income. For example, a hypothetical 10% adverse movement in the exchange rate between the U.S. dollar and the Japanese yen would have resulted in a $4.6 million decrease in our total revenue and a $3.4

38


million decrease in our operating income for the year ended December 31, 2014, and a hypothetical 10% favorable movement in the exchange rate between the U.S. dollar and the Japanese yen would have resulted in a $4.6 million increase in our total revenue and a $3.4 million increase in operating income for the year ended December 31, 2014.  As exchange rates vary, our operating income may differ from expectations.

To date, we have not entered into any hedging arrangements with respect to foreign currency risk or other derivative instruments. In the future, however, to the extent our foreign currency exposures become more material, we may elect to deploy normal and customary hedging practices designed to more proactively mitigate such exposure. The use of such hedging activities may not offset any, or more than a portion, of the adverse financial effects of unfavorable movements in currency exchange rates over the limited time the hedges are in place and would not protect us from long term shifts in currency exchange rates.

Our success depends on our key personnel and our ability to hire, retain and motivate qualified product development, sales, marketing and finance personnel.

Our success depends to a significant degree upon the continued contributions of our key management, product development, sales, marketing and finance personnel, many of whom may be difficult to replace. The complexity of our products, their integration into existing networks and ongoing support of our products requires us to retain highly trained professional services, customer support and sales personnel with specific expertise related to our business. Competition for qualified professional services, customer support, engineering and sales personnel in our industry is intense, because of the limited number of people available with the necessary technical skills and understanding of our products. Our ability to recruit and hire these personnel is harmed by tightening labor markets, particularly in the engineering field, in several of our key geographic hiring areas. We may not be successful in attracting, integrating, or retaining qualified personnel to fulfill our current or future needs, nor may we be successful in keeping the qualified personnel we currently have. Our ability to hire and retain these personnel may be adversely affected by volatility or reductions in the price of our common stock, since these employees are generally granted equity-based awards. Also, to the extent we hire personnel from competitors, we may be subject to allegations that they have been improperly solicited, or that they have divulged proprietary or other confidential information, or that their former employers own their inventions or other work product.

Our future performance also depends on the continued services and continuing contributions of our senior management to execute on our business plan and to identify and pursue new opportunities and product innovations. In particular, Lee Chen, our founder and Chief Executive Officer, and Rajkumar Jalan, our Chief Technology Officer, are critical to the development of our technology and the future vision and strategic direction of our company. The loss of services of senior management could significantly delay or prevent the achievement of our development and strategic objectives, which could adversely affect our business, financial condition, and operating results.

We are obligated to implement and maintain effective internal control over financial reporting. We may not complete our analysis of our internal control over financial reporting in a timely manner, or our internal control over financial reporting may not be determined to be effective, which may adversely affect investor confidence in our company and, as a result, the value of our common stock.

We are required, pursuant to the Exchange Act, to furnish a report by management on, among other things, the effectiveness of our internal control over financial reporting for each fiscal year beginning with fiscal 2015. This assessment will need to include disclosure of any material weaknesses identified by our management in our internal control over financial reporting, such as the material weakness described in the following risk factor that we discovered in connection with our review of internal control over financial reporting as of December 31, 2014.

We are currently evaluating our internal controls, identifying and remediating deficiencies and the identified material weakness in those internal controls and documenting the results of our evaluation, testing and remediation. We may not be able to complete our evaluation, testing and any required remediation in a timely fashion. During the evaluation and testing process, if we identify one or more material weaknesses in our internal control over financial reporting that we are unable to remediate before the end of the same fiscal year in which the material weakness is identified, we will be unable to assert that our internal control over financial reporting is effective. If we are unable to conclude that our internal control over financial reporting is effective, if our auditors are unable to attest to management’s report on the effectiveness of our internal control over financial reporting, or if we are required to restate our financial statements as a result of ineffective internal control over financial reporting, we could lose investor confidence in the accuracy and completeness of our financial reports, which would cause the price of our common stock to decline.


39


We are required to disclose material changes made in our internal control and procedures on a quarterly basis. However, our independent registered public accounting firm will not be required to formally attest to the effectiveness of our internal control over financial reporting pursuant to Section 404 of the Sarbanes-Oxley Act until the later of the year following our first annual report required to be filed with the SEC or the date we are no longer an emerging growth company as defined in the JOBS Act, if we take advantage of the exemptions contained in the JOBS Act. To comply with these requirements, we may need to undertake various actions, such as implementing new internal controls and procedures and hiring accounting or internal audit staff.

We have identified a material weakness in our internal control over the computation of share-based compensation expense related to our 2014 Employee Stock Purchase Plan, and our business and stock price may be materially adversely affected if we do not adequately address this material weakness or if we have other material weaknesses in our internal control over financial reporting.

In connection with our review of internal control over financial reporting as of December 31, 2014, we determined that we did not adequately implement certain controls over the computation of share-based compensation related to our 2014 Employee Stock Purchase Plan, and we have therefore concluded that a material weakness in our internal control over financial reporting existed as of December 31, 2014. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of a company's annual or interim financial statements will not be prevented or detected on a timely basis. In order to remediate this material weakness, during the first nine months of 2015, we implemented new review procedures and controls relating to the computation of stock-based compensation expense related to our 2014 Purchase Plan. Although we have taken these actions to remediate this material weakness, we cannot guarantee that the changes we made to our controls and processes will be effective in maintaining the adequacy of our internal controls in future reporting periods.

The existence of this material weakness or the discovery of one or more other material weaknesses or significant deficiencies in our internal control over financial reporting could result in errors in our financial statements, and substantial costs and resources may be required to rectify any internal control deficiencies. Although we continually review and evaluate internal control systems, we have in the past discovered significant deficiencies and we cannot assure you that we will not discover additional significant deficiencies or material weaknesses in our internal control over financial reporting. Any such additional significant deficiency or material weakness or failure to remediate the existing material weakness could materially adversely affect our ability to comply with applicable financial reporting requirements. Further, if we cannot produce reliable financial reports, investors could lose confidence in our reported financial information, the market price of our stock could decline significantly, and our business, financial condition and results of operations could be materially harmed.

If we are not able to maintain and enhance our brand and reputation, our business and operating results may be harmed in tangible or intangible ways.

We believe that maintaining and enhancing our brand and reputation are critical to our relationships with, and our ability to attract, new end-customers, technology partners and employees. The successful promotion of our brand will depend largely upon our ability to continue to develop, offer and maintain high-quality products and services, our marketing and public relations efforts, and our ability to differentiate our products and services successfully from those of our competitors. Our brand promotion activities may not be successful and may not yield increased revenue. In addition, extension of our brand to products and uses different from our traditional products and services may dilute our brand, particularly if we fail to maintain the quality of products and services in these new areas. We have in the past, and may in the future, become involved in litigation that could negatively affect our brand. If we do not successfully maintain and enhance our brand and reputation, our growth rate may decline, we may have reduced pricing power relative to competitors with stronger brands or reputations, and we could lose end-customers or technology partners, all of which would harm our business, operating results and financial condition.

Adverse general economic conditions or reduced information technology spending may adversely impact our business.

A substantial portion of our business depends on the demand for information technology by large enterprises and service providers, the overall economic health of our current and prospective end-customers and the continued growth and evolution of the Internet. The timing of the purchase of our products is often discretionary and may involve a significant commitment of capital and other resources. While some economic indicators have recently improved, there are still lingering effects of economic weakness from the recent financial recession, including more limited availability of credit, a reduction in business confidence and activity, deficit-driven austerity measures that continue to affect governments and educational institutions, and other difficulties that may affect one or more of the industries to which we sell our products and services. If economic conditions in the United States, Europe and other key markets for our products do not continue to improve or those markets experience another downturn, many end-customers may delay or reduce their IT spending. This could result in

40


reductions in sales of our products and services, longer sales cycles, slower adoption of new technologies and increased price competition. Any of these events would likely harm our business, operating results and financial condition. In addition, there can be no assurance that IT spending levels will increase following any recovery.

We are dependent on third-party manufacturers, and changes to those relationships, expected or unexpected, may result in delays or disruptions that could harm our business.

We outsource the manufacturing of our hardware components to third-party original design manufacturers who assemble these hardware components to our specifications. Our primary manufacturers are Lanner Electronics, Inc. and AEWIN Technologies Co., Ltd., each of which is located in Taiwan. Our reliance on these third-party manufacturers reduces our control over the manufacturing process and exposes us to risks, including reduced control over quality assurance, product costs, and product supply and timing. Any manufacturing disruption at these manufacturers could severely impair our ability to fulfill orders. Our reliance on outsourced manufacturers also may create the potential for infringement or misappropriation of our intellectual property rights or confidential information. If we are unable to manage our relationships with these manufacturers effectively, or if these manufacturers suffer delays or disruptions for any reason, experience increased manufacturing lead-times, experience capacity constraints or quality control problems in their manufacturing operations, or fail to meet our future requirements for timely delivery, our ability to ship products to our end-customers would be severely impaired, and our business and operating results would be seriously harmed.

These manufacturers typically fulfill our supply requirements on the basis of individual orders. We do not have long-term contracts with our manufacturers that guarantee capacity, the continuation of particular pricing terms, or the extension of credit limits. Accordingly, they are not obligated to continue to fulfill our supply requirements, which could result in supply shortages, and the prices we are charged for manufacturing services could be increased on short notice. In addition, our orders may represent a relatively small percentage of the overall orders received by our manufacturers from their customers. As a result, fulfilling our orders may not be considered a priority by one or more of our manufacturers in the event the manufacturer is constrained in its ability to fulfill all of its customer obligations in a timely manner.

Although the services required to manufacture our hardware components may be readily available from a number of established manufacturers, it is time-consuming and costly to qualify and implement such relationships. If we are required to change manufacturers, whether due to an interruption in one of our manufacturers’ businesses, quality control problems or otherwise, or if we are required to engage additional manufacturers, our ability to meet our scheduled product deliveries to our customers could be adversely affected, which could cause the loss of sales to existing or potential customers, delayed revenue or an increase in our costs that could adversely affect our gross margin.

Because some of the key components in our products come from limited sources of supply, we are susceptible to supply shortages or supply changes, which could disrupt or delay our scheduled product deliveries to our end-customers and may result in the loss of sales and end-customers.

Our products incorporate key components, including certain integrated circuits that we and our third-party manufacturers purchase on our behalf from a limited number of suppliers, including some sole-source providers. In addition, the lead times associated with these and other components of our products can be lengthy and preclude rapid changes in quantities and delivery schedules. Moreover, long-term supply and maintenance obligations to our end-customers increase the duration for which specific components are required, which may further increase the risk we may incur component shortages or the cost of carrying inventory. If we are unable to obtain a sufficient quantity of these components in a timely manner for any reason, sales and/or shipments of our products could be delayed or halted, which would seriously affect present and future sales and cause damage to end-customer relationships, which would, in turn, adversely affect our business, financial condition and results of operations.

In addition, our component suppliers change their selling prices frequently in response to market trends, including industry-wide increases in demand, and because we do not necessarily have contracts with these suppliers, we are susceptible to price fluctuations related to raw materials and components. If we are unable to pass component price increases along to our end-customers or maintain stable pricing, our gross margin and operating results could be negatively impacted. Furthermore, poor quality in sole-sourced components or certain other components in our products could also result in lost sales or lost sales opportunities. If the quality of such components does not meet our standards or our end-customers’ requirements, if we are unable to obtain components from our existing suppliers on commercially reasonable terms, or if any of our sole source providers cease to continue to manufacture such components or to remain in business, we could be forced to redesign our products and qualify new components from alternate suppliers. The development of alternate sources for those components can be time-consuming, difficult and costly, and we may not be able to develop alternate or second sources in a timely manner.

41


Even if we are able to locate alternate sources of supply, we could be forced to pay for expedited shipments of such components or our products at dramatically increased costs.

Real or perceived defects, errors, or vulnerabilities in our products or services or the failure of our products or services to block a threat or prevent a security breach could harm our reputation and adversely impact our results of operations.

Because our products and services are complex, they have contained and may contain design or manufacturing defects or errors that are not detected until after their commercial release and deployment by our end-customers. Even if we discover those weaknesses, we may not be able to correct them promptly, if at all. Defects may cause our products to be vulnerable to security attacks, cause them to fail to help secure networks, or temporarily interrupt end-customers’ networking traffic. Furthermore, our products may fail to detect or prevent malware, viruses, worms or similar threats for any number of reasons, including our failure to enhance and expand our platform to reflect industry trends, new technologies and new operating environments, the complexity of the environment of our end-customers and the sophistication of malware, viruses and other threats. Data thieves and hackers are increasingly sophisticated, often affiliated with organized crime and may operate large-scale and complex automated attacks. The techniques used to obtain unauthorized access or to sabotage networks change frequently and may not be recognized until launched against a target. Additionally, as a well-known provider of enterprise security solutions, our networks, products, and services could be targeted by attacks specifically designed to disrupt our business and harm our reputation. As our products are adopted by an increasing number of enterprises and governments, it is possible that the individuals and organizations behind advanced attacks will focus on finding ways to defeat our products. In addition, defects or errors in our updates to our products could result in a failure of our services to effectively update end-customers’ products and thereby leave our end-customers vulnerable to attacks. Our data centers and networks may experience technical failures and downtime, may fail to distribute appropriate updates, or may fail to meet the increased requirements of a growing installed end-customer base, any of which could temporarily or permanently expose our end-customers’ networks, leaving their networks unprotected against security threats. Our end-customers may also misuse our products, which may result in loss or a breach of business data. For all of these reasons, we may be unable to anticipate all data security threats or provide a solution in time to protect our end-customers’ networks. If we fail to identify and respond to new and increasingly complex methods of attack and to update our products to detect or prevent such threats in time to protect our end-customers’ critical business data, our business, operating results and reputation could suffer.

If any companies or governments that are publicly known to use our platform are the subject of an advanced cyberattack that becomes publicized, our other current or potential channel partners or end-customers may look to our competitors for alternatives to our products. Real or perceived security breaches of our end-customers’ networks could cause disruption or damage to their networks or other negative consequences and could result in negative publicity to us, damage to our reputation, declining sales, increased expenses and end-customer relations issues. To the extent potential end-customers or industry analysts believe that the occurrence of any actual or perceived failure of our products to detect or prevent malware, viruses, worms or similar threats is a flaw or indicates that our products do not provide significant value, our reputation and business could be harmed.

Any real or perceived defects, errors, or vulnerabilities in our products, or any failure of our products to detect a threat, could result in:
a loss of existing or potential end-customers or channel partners;

delayed or lost revenue;

a delay in attaining, or the failure to attain, market acceptance;

the expenditure of significant financial and product development resources in efforts to analyze, correct, eliminate, or work around errors or defects, to address and eliminate vulnerabilities, or to identify and ramp up production with third-party providers;

an increase in warranty claims, or an increase in the cost of servicing warranty claims, either of which would adversely affect our gross margins;

harm to our reputation or brand; and

litigation, regulatory inquiries, or investigations that may be costly and further harm our reputation.   


42


Failure to protect and ensure the confidentiality and security of data could lead to legal liability, adversely affect our reputation and have a material adverse effect on our operating results, business and reputation.

We may collect, store and use certain confidential information in the course of providing our services, and we have invested in preserving the security of this data. We may also outsource operations to third-party service providers to whom we transmit certain confidential data. There are no assurances that any security measures we have in place, or any additional security measures that our subcontractors may have in place, will be sufficient to protect this confidential information from unauthorized security breaches.

We cannot assure you that, despite the implementation of these security measures, we will not be subject to a security incident or other data breach or that this data will not be compromised. We may be required to expend significant capital and other resources to protect against security breaches or to alleviate problems caused by security breaches, or to pay penalties as a result of such breaches. Despite our implementation of security measures, techniques used to obtain unauthorized access or to sabotage systems change frequently and may not be recognized until launched against a target. As a result, we may be unable to anticipate these techniques or implement adequate preventative measures to protect this data. In addition, security breaches can also occur as a result of non-technical issues, including intentional or inadvertent breaches by our employees or service providers or by other persons or entities with whom we have commercial relationships. Any compromise or perceived compromise of our security could damage our reputation with our end-customers, and could subject us to significant liability, as well as regulatory action, including financial penalties, which would materially adversely affect our brand, results of operations, financial condition, business and prospects.

We have incurred, and expect to continue to incur, significant costs to protect against security breaches. We may incur significant additional costs in the future to address problems caused by any actual or perceived security breaches.

Breaches of our security measures or those of our third-party service providers, or other security incidents, could result in unauthorized access to our sites, networks and systems; unauthorized access to, misuse or misappropriation of information, including personally identifiable information, or other confidential or proprietary information of ourselves or third parties; viruses, worms, spyware or other malware being served from our sites, networks or systems; deletion or modification of content or the display of unauthorized content on our sites; interruption, disruption or malfunction of operations; costs relating to notification of individuals, or other forms of breach remediation; deployment of additional personnel and protection technologies; response to governmental investigations and media inquiries and coverage; engagement of third party experts and consultants; litigation, regulatory investigations, prosecutions, and other actions, and other potential liabilities. If any of these events occurs, or is believed to occur, our reputation and brand could be damaged, our business may suffer, we could be required to expend significant capital and other resources to alleviate problems caused by such actual or perceived breaches, we could be exposed to a risk of loss, litigation or regulatory action and possible liability, and our ability to operate our business, including our ability to provide maintenance and support services to our channel partners and end-customers, may be impaired. If current or prospective channel partners and end-customers believe that our systems and solutions do not provide adequate security for their businesses’ needs, our business and our financial results could be harmed. Additionally, actual, potential or anticipated attacks may cause us to incur increasing costs, including costs to deploy additional personnel and protection technologies, train employees and engage third-party experts and consultants.

Although we maintain privacy, data breach and network security liability insurance, we cannot be certain that our coverage will be adequate for liabilities actually incurred or that insurance will continue to be available to us on economically reasonable terms, or at all. Any actual or perceived compromise or breach of our security measures, or those of our third-party service providers, or any unauthorized access to, misuse or misappropriation of personally identifiable information, channel partners’ or end-customers information, or other information, could violate applicable laws and regulations, contractual obligations or other legal obligations and cause significant legal and financial exposure, adverse publicity and a loss of confidence in our security measures, any of which could have an material adverse effect on our business, financial condition and operating results.

Our failure to adequately protect personal data could have a material adverse effect on our business.

A wide variety of provincial, state, national, foreign, and international laws and regulations apply to the collection, use, retention, protection, disclosure, transfer, and other processing of personal data. These data protection and privacy-related laws and regulations are evolving and being tested in courts and may result in ever-increasing regulatory and public scrutiny and escalating levels of enforcement and sanctions. Our failure to comply with applicable laws and regulations, or to protect such data, could result in enforcement action against us, including fines, imprisonment of company officials and public censure, claims for damages by end-customers and other affected persons and entities, damage to our reputation and loss of goodwill (both in relation to existing and prospective channel partners and end-customers), and other forms of injunctive or operations-

43


limiting relief, any of which could have a material adverse effect on our operations, financial performance, and business. Evolving and changing definitions of personal data and personal information, within the European Union, the United States, and elsewhere, especially relating to classification of Internet Protocol (IP) addresses, machine identification, location data, and other information, may limit or inhibit our ability to operate or expand our business, including limiting strategic partnerships that may involve the sharing of data. We may be required to expend significant resources to modify our solutions and otherwise adapt to these changes, which we may be unable to do on commercially reasonable terms or at all, and our ability to develop new solutions and features could be limited. These developments could harm our business, financial condition and results of operations. Even if not subject to legal challenge, the perception of privacy concerns, whether or not valid, may harm our reputation and inhibit adoption of our products by current and prospective end-customers.

If the general level of advanced cyberattacks declines, or is perceived by our current or potential customers to have declined, our business could be harmed.

Our security business may be dependent on enterprises and governments recognizing that advanced cyberattacks are pervasive and are not effectively prevented by legacy security solutions. High visibility attacks on prominent companies and governments have increased market awareness of advanced cyberattacks and help to provide an impetus for enterprises and governments to devote resources to protecting against advanced cyberattacks, which may include testing, purchasing, and deploying our products. If advanced cyberattacks were to decline, or enterprises or governments perceived a decline in the general level of advanced cyberattacks, our ability to attract new channel partners and end-customers and expand our offerings within existing channel partners and end-customers could be materially and adversely affected. An actual or perceived reduction in the threat landscape could increase our sales cycles and harm our business, results of operations and financial condition.

Undetected software or hardware errors may harm our business and results of operations.

Our products may contain undetected errors or defects when first introduced or as new versions are released. We have experienced these errors or defects in the past in connection with new products and product upgrades. We expect that these errors or defects will be found from time to time in new or enhanced products after commencement of commercial distribution. These problems may cause us to incur significant warranty and repair costs, divert the attention of our engineering personnel from our product development efforts and cause significant customer relations problems. We may also be subject to liability claims for damages related to product errors or defects. While we carry insurance policies covering this type of liability, these policies may not provide sufficient protection should a claim be asserted. A material product liability claim may harm our business and results of operations.

Any errors, defects or vulnerabilities in our products could result in:

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

loss of existing or potential end-customers or distribution channel partners;

delayed or lost revenue;

delay or failure to attain market acceptance;

indemnification obligations under our agreements with resellers, distributors and/or end-customers;

an increase in warranty claims compared with our historical experience or an increased cost of servicing warranty claims, either of which would adversely affect our gross margin; and

litigation, regulatory inquiries, or investigations that may be costly and harm our reputation.

Our use of open source software in our products could negatively affect our ability to sell our products and subject us to possible litigation.

We incorporate open source software such as the Linux operating system kernel into our products. We recently implemented a formal open source use policy, including written guidelines for use of open source software and business processes for approval of that use. We have developed and implemented our open source policies according to industry practice; however, best practices in this area are subject to change, because there is little reported case law on the interpretation

44


of material terms of many open source licenses. We are in the process of reviewing our open source use and our compliance with open source licenses and implementing remediation and changes necessary to comply with the open source licenses related thereto. We cannot guarantee that our use of open source software has been, and will be, managed effectively for our intended business purposes and/or compliant with applicable open source licenses. We may face legal action by third parties seeking to enforce their intellectual property rights related to our use of such open source software. Failure to adequately manage open source license compliance and our use of open source software may result in unanticipated obligations regarding our products and services, such as a requirement that we license proprietary portions of our products or services on unfavorable terms, that we make available source code for modifications or derivative works we created based upon, incorporating or using open source software, that we license such modifications or derivative works under the terms of the particular open source license and/or that we redesign the affected products or services, which could result, for example, in a loss of intellectual property rights, or delay in providing our products and services. From time to time, there have been claims against companies that distribute or use third-party open source software in their products and services, asserting that the open source software or its combination with the products or services infringes third parties’ patents or copyrights, or that the companies’ distribution or use of the open source software does not comply with the terms of the applicable open source licenses. Use of certain open source software can lead to greater risks than use of warranted third-party commercial software, as open source licensors generally do not provide warranties or controls on the origin of such open source software. From time to time, there have been claims against companies that use open source software in their products, challenging the ownership of rights in such open source software. As a result, we could also be subject to suits by parties claiming ownership of rights in what we believe to be open source software and so challenging our right to use such software in our products. If any such claims were asserted against us, we could be required to incur significant legal expenses defending against such a claim. Further, if our defenses to such a claim were not successful, we could be, for example, subject to significant damages, be required to seek licenses from third parties in order to continue offering our products and services without infringing such third party’s intellectual property rights, be required to re-engineer such products and services, or be required to discontinue making available such products and services if re-engineering cannot be accomplished on a timely or successful basis. The need to engage in these or other remedies could increase our costs or otherwise adversely affect our business, operating results and financial condition.

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

Our products must interoperate with our end-customers’ existing infrastructure, specifically their networks, servers, software and operating systems, which may be manufactured by a wide variety of vendors and original equipment manufacturers. As a result, when problems occur in a network, it may be difficult to identify the source of the problem. The occurrence of software or hardware problems, whether caused by our products or another vendor’s products, may result in the delay or loss of market acceptance of our products. In addition, when new or updated versions of our end-customers’ software operating systems or applications are introduced, we must sometimes develop updated versions of our software so that our products will interoperate properly. We may not accomplish these development efforts quickly, cost-effectively or at all. These development efforts require capital investment and the devotion of engineering resources. If we fail to maintain compatibility with these applications, our end-customers may not be able to adequately utilize our products, and we may, among other consequences, fail to increase, or we may lose market share and experience a weakening in demand for our products, which would adversely affect our business, operating results and financial condition.

We license technology from third parties, and our inability to maintain those licenses could harm our business.

Many of our products include proprietary technologies licensed from third parties. In the future, it may be necessary to renew licenses for third party technology or obtain new licenses for other technology. These third party licenses may not be available to us on acceptable terms, if at all. As a result, we could also face delays or be unable to make changes to our products until equivalent technology can be identified, licensed or developed and integrated with our products. Such delays or an inability to make changes to our products, if it were to occur, could adversely affect our business, operating results and financial condition. The inability to obtain certain licenses to third-party technology, or litigation regarding the interpretation or enforcement of license agreements and related intellectual property issues, could have a material adverse effect on our business, operating results and financial condition.

Failure to prevent excess inventories or inventory shortages could result in decreased revenue and gross margin and harm our business.

We purchase products from our manufacturers outside of, and in advance of, reseller or end-customer orders, which we hold in inventory and resell. We place orders with our manufacturers based on our forecasts of our end-customers’

45


requirements and forecasts provided by our distribution channel partners. These forecasts are based on multiple assumptions, each of which might cause our estimates to be inaccurate, affecting our ability to provide products to our customers. There is a risk we may be unable to sell excess products ordered from our manufacturers. Inventory levels in excess of customer demand may result in obsolete inventory and inventory write-downs. The sale of excess inventory at discounted prices could impair our brand image and have an adverse effect on our financial condition and results of operations. Conversely, if we underestimate demand for our products or if our manufacturers fail to supply products we require at the time we need them, we may experience inventory shortages. Inventory shortages might delay shipments to resellers, distributors and customers and cause us to lose sales. These shortages may diminish the loyalty of our distribution channel partners or customers.

The difficulty in forecasting demand also makes it difficult to estimate our future financial condition and results of operations from period to period. A failure to accurately predict the level of demand for our products could adversely affect our net revenue and net income, and we are unlikely to forecast such effects with any certainty in advance. For example, we failed to predict the slowdown in the United States sales during the three months ended September 30, 2014 which resulted in lower revenues, gross margin and net income than expected.

Our sales cycles can be long and unpredictable, primarily due to the complexity of our end-customers’ networks and data centers and the length of their budget cycles. As a result, our sales and revenue are difficult to predict and may vary substantially from period to period, which may cause our operating results to fluctuate significantly.

The timing of our sales is difficult to predict because of the length and unpredictability of our products’ sales cycles. A sales cycle is the period between initial contact with a prospective end-customer and any sale of our products. Our sales cycle, in particular to our large end-customers, may be lengthy due to the complexity of their networks and data centers. Because of this complexity, prospective end-customers generally consider a number of factors over an extended period of time before committing to purchase our products. End-customers often view the purchase of our products as a significant and strategic decision that can have important implications on their existing networks and data centers and, as a result, require considerable time to evaluate, test and qualify our products prior to making a purchase decision and placing an order to ensure that our products will successfully interoperate with our end-customers’ complex network and data centers. Additionally, the budgetary decisions at these entities can be lengthy and require multiple organization reviews. The length of time that end-customers devote to their evaluation of our products and decision making process varies significantly. The length of our products’ sales cycles typically ranges from three to 12 months but can be longer for our large end-customers. In addition, the length of our close or sales cycle can be affected by the extent to which customized features are requested, in particular in our large deals.

For all of these reasons, it is difficult to predict whether a sale will be completed or the particular fiscal period in which a sale will be completed, both of which contribute to the uncertainty of our future operating results. If our close or sales cycles lengthen, our revenue could be lower than expected, which would have an adverse impact on our operating results and could cause our stock price to decline. For example, during the three months ended September 30, 2014, we experienced longer than expected close and sales cycles for certain large deals and a 62% decrease in North America service provider revenue as compared to the same period in 2013 that adversely affected our revenue and may have contributed to a dramatic decline in our stock price.

Our ability to sell our products is highly dependent on the quality of our support and services offerings, and our failure to offer high-quality support could have a material adverse effect on our business, revenue and results of operations.

We believe that our ability to provide consistent, high quality customer service and technical support is a key factor in attracting and retaining end-customers of all sizes and is critical to the deployment of our products. When support is purchased our end-customers depend on our support organization to provide a broad range of support services, including on-site technical support, 24-hour support and shipment of replacement parts on an expedited basis. If our support organization or our distribution channel partners do not assist our end-customers in deploying our products effectively, succeed in helping our end-customers resolve post-deployment issues quickly, or provide ongoing support, it could adversely affect our ability to sell our products to existing end-customers and could harm our reputation with potential end-customers. We currently have technical support centers in the United States, Japan, China and the Netherlands. As we continue to expand our operations internationally, our support organization will face additional challenges, including those associated with delivering support, training and documentation in languages other than English.

We typically sell our products with maintenance and support as part of the initial purchase, and a substantial portion of our support revenue comes from renewals of maintenance and support contracts. Our end-customers have no obligation to renew their maintenance and support contracts after the expiration of the initial period. If we are unable to provide high quality support, our end-customers may elect not to renew their maintenance and support contracts or to reduce the product quantity under their maintenance and support contracts, thereby reducing our future revenue from maintenance and support contracts.

46



Our failure or the failure of our distribution channel partners to maintain high-quality support and services could have a material and adverse effect on our business, revenue and operating results.

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 results of operations 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. 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. If this demand declines, our results of operations and financial condition would be materially and adversely affected. Segments of the network infrastructure industry have in the past experienced significant economic downturns. Furthermore, the market for network infrastructure may not continue to grow at historic rates, or at all. The occurrence of any of these factors in the markets relating to network security, management and analysis could materially and adversely affect our results of operations and financial condition. For example, during the three months ended September 30, 2014, we experienced a 62% decrease in North America service provider revenue as compared to the same period in 2013 that adversely affected our revenue and may have contributed to a dramatic decline in our stock price. We anticipate a possible slowdown in North America service providers, which may lead to continued near term fluctuation in our product revenue and total revenue.

Our revenue growth rate in recent periods may not be indicative of our future performance.

You should not consider our revenue growth rate in recent periods as indicative of our future performance. We have recently experienced revenue growth rates of 32%, 18% and 27% in 2012, 2013 and 2014 as compared to the same prior periods. We may not achieve similar revenue growth rates in future periods. You should not rely on our revenue for any prior quarterly or annual periods as any indication of our future revenue or revenue growth. If we are unable to maintain consistent revenue or revenue growth, our stock price could be volatile, and it may be difficult to achieve and maintain profitability. For example, our sequential product growth rate between the three months ended June 30, 2014 and September 30, 2014 was a negative 7% and was lower than expected which resulted in a decline in our stock price.

Our business and operations have experienced rapid growth in recent periods, and if we do not effectively manage any future growth or are unable to improve our controls, systems and processes, our operating results will be adversely affected.

In recent periods, we have significantly increased the number of our employees and independent contractors. As we hire new employees and independent contractors and expand into new locations outside the United States, we are required to comply with varying local laws for each of these new locations. We anticipate that further expansion of our infrastructure and headcount will be required. Our rapid growth has placed, and will continue to place, a significant strain on our administrative and operational infrastructure and financial resources. Our ability to manage our operations and growth across multiple countries will require us to continue to refine our operational, financial and management controls, human resource policies, and reporting systems and processes.

We need to continue to improve our internal systems, processes, and controls to effectively manage our operations and growth. We may not be able to successfully implement improvements to these systems, processes and controls in an efficient or timely manner. In addition, our systems and processes may not prevent or detect all errors, omissions, or fraud. We may experience difficulties in managing improvements to our systems, processes, and controls or in connection with third-party software, which could impair our ability to provide products or services to our customers in a timely manner, causing us to lose customers, limit us to smaller deployments of our products, increase our technical support costs, or damage our reputation and brand. Our failure to improve our systems and processes, or their failure to operate in the intended manner, may result in our inability to manage the growth of our business and to accurately forecast our revenue, expenses, and earnings, or to prevent certain losses, any of which may harm our business and results of operations.

We may not be able to sustain or develop new distributor and reseller relationships, and a reduction or delay in sales to significant distribution channel partners could hurt our business.

We sell our products and services through multiple distribution channels in the United States and internationally. We may not be able to increase our number of distributor or reseller relationships or maintain our existing relationships. Recruiting and retaining qualified distribution channel partners and training them on our technologies requires significant time and resources. These distribution channel partners may also market, sell and support products and services that are competitive with ours and may devote more resources to the marketing, sales and support of such competitive products. Our sales channel

47


structure could subject us to lawsuits, potential liability and reputational harm if, for example, any of our distribution channel partners misrepresent the functionality of our products or services to end-customers or violate laws or our corporate policies. If we are unable to establish or maintain our sales channels or if our distribution channel partners are unable to adapt to our future sales focus and needs, our business and results of operations will be harmed.

The terms of our credit facility could restrict our operations, particularly our ability to respond to changes in our business or to take specified actions.

Our credit facility contains a number of restrictive covenants that impose operating and financial restrictions on us, including restrictions on our ability to take actions that may be in our best interests. Our credit facility requires us to satisfy specified financial covenants. In the past, we were not in compliance with one of the covenants on one occasion and were able to obtain a waiver from our lenders regarding the non-compliance. Our ability to meet those financial covenants can be affected by events beyond our control, and we may not be able to continue to meet those covenants or obtain waivers if we fail to meet a covenant. Upon the occurrence of an event of default, our lenders could elect to declare all amounts outstanding under the credit facility to be immediately due and payable and terminate all commitments to extend further credit. If our lenders accelerate the repayment, if any, we may not have sufficient funds to repay our existing debt. If we were unable to repay those amounts, our lenders could proceed against the collateral granted to them to secure such indebtedness. We have pledged substantially all of our assets, including our intellectual property, as collateral under the credit facility. As of September 30, 2015, we had no outstanding balance on our credit facility and were in compliance with the covenants.

Our sales to governmental organizations are subject to a number of challenges and risks.

We sell to governmental organization end-customers. Sales to governmental organizations are subject to a number of challenges and risks. Selling to governmental organizations can be highly competitive, expensive and time consuming, often requiring significant upfront time and expense without any assurance that these efforts will generate a sale. We have not yet received security clearance from the United States government, which prevents us from being able to sell directly for certain governmental uses. There can be no assurance that such clearance will be obtained, and failure to do so may adversely affect our operating results. Governmental organization demand and payment for our products may be impacted by public sector budgetary cycles and funding authorizations, with funding reductions or delays adversely affecting public sector demand for our products. Governmental organizations 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 future operating results.

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

Our business is subject to regulation by various federal, state, local and foreign governmental entities, including agencies responsible for monitoring and enforcing employment and labor laws, workplace safety, product safety, environmental laws, consumer protection laws, anti-bribery laws, import/export controls, federal securities laws, and tax laws and regulations. In certain jurisdictions, these regulatory requirements may be more stringent than those in the United States. Noncompliance with applicable regulations or requirements could subject us to investigations, sanctions, mandatory product recalls, enforcement actions, disgorgement of profits, fines, damages, 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.


48


We are subject to governmental export and import controls that could subject us to liability or impair our ability to compete in international markets.

Our products are subject to U.S. export controls and may be exported outside the United States only with the required level of export license or through an export license exception because we incorporate encryption technology into our products. In addition, various countries regulate the import of certain encryption technology and have enacted laws that could limit our ability to distribute our products or our end-customers’ ability to implement our products in those countries. Changes in our products or changes in export and import regulations may create delays in the introduction of our products in international markets, prevent our end-customers with international operations from deploying our products throughout their global systems or, in some cases, prevent the export or import of our products to certain countries altogether. Any change in export or import regulations or related legislation, shift in approach to the enforcement or scope of existing regulations or change in the countries, persons or technologies targeted by such regulations, could result in decreased use of our products by, or in our decreased ability to export or sell our products to, existing or potential end-customers with international operations. Any decreased use of our products or limitation on our ability to export or sell our products would likely adversely affect our business, operating results and financial condition.

We discovered that we inadvertently reported incorrect information to the U.S. Census Bureau when reporting certain exports, although the underlying exports were authorized under the Export Administration Regulations. We implemented corrective actions and filed a Voluntary Self Disclosure with the U.S. Census Bureau regarding these technical violations. The Census Bureau closed the voluntary self-disclosure in October, 2014 without imposition of any fines or penalties.

We are subject to various environmental laws and regulations that could impose substantial costs upon us.

Our company must comply with local, state, federal, and international environmental laws and regulations in the countries in which we do business. We are also subject to laws, which restrict certain hazardous substances, including lead, used in the construction of our products, such as the European Union Restriction on the Use of Hazardous Substances in electrical and electronic equipment directive. We are also subject to the European Union Directive, known as the Waste Electrical and Electronic Equipment Directive, or WEEE Directive, which requires producers of certain electrical and electronic equipment to properly label products, register as a WEEE producer, and provide for the collection, disposal, and recycling of waste electronic products. Failure to comply with these environmental directives and other environmental laws could result in the imposition of fines and penalties, inability to sell covered products in certain countries, the loss of revenue, or subject us to third-party property damage or personal injury claims, or require us to incur investigation, remediation or engineering costs. Our operations and products will be affected by future environmental laws and regulations, but we cannot predict the ultimate impact of any such future laws and regulations at this time.

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

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

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

Many of our business processes depend upon our information technology systems, the systems and processes of third parties, and on interfaces with the systems of third parties. 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 could harm our ability to ship or support our products, and our financial results may be harmed.

In addition, reconfiguring or upgrading our information technology systems or other business processes in response to changing business needs may be time-consuming and costly and is subject to risks of delay or failed deployment. To the extent this impacts our ability to react timely to specific market or business opportunities, our financial results may be harmed.


49


Future acquisitions we may undertake may not result in the financial and strategic goals that are contemplated at the time of the transaction.

We may make acquisitions of complementary companies, products or technologies. With respect to any other future acquisitions we may undertake, we may find that the acquired businesses, products or technologies do not further our business strategy as expected, that we paid more than what the assets are later worth or that economic conditions change, all of which may generate future impairment charges. Any future acquisitions may be viewed negatively by customers, financial markets or investors. There may be difficulty integrating the operations and personnel of an acquired business, and we may have difficulty retaining the key personnel of an acquired business. We may have difficulty in integrating acquired technologies or products with our existing product lines. Any integration process may require significant time and resources, and we may not be able to manage the process successfully. Our ongoing business and management’s attention may be disrupted or diverted by transition or integration issues and the complexity of managing geographically and culturally diverse locations. We may have difficulty maintaining uniform standards, controls, procedures and policies across locations. We may experience significant problems or liabilities associated with product quality, technology and other matters.

Our inability to successfully operate and integrate future acquisitions appropriately, effectively and in a timely manner, or to retain key personnel of any acquired business, could have a material adverse effect on our revenue, gross margin and expenses.

Our ability to use our net operating loss carryforwards may be subject to limitation and may result in increased future tax liability to us.

Generally, a change of more than 50% in the ownership of a corporation’s stock, by value, over a three-year period constitutes an ownership change for U.S. federal income tax purposes. An ownership change may limit a company’s ability to use its net operating loss carryforwards attributable to the period prior to such change. In the event we have undergone an ownership change under Section 382 of the Internal Revenue Code, if we earn net taxable income, our ability to use our pre-change net operating loss carryforwards to offset U.S. federal taxable income may become subject to limitations, which could potentially result in increased future tax liability to us.

Unanticipated changes in effective tax rates or adverse outcomes resulting from examination of our income or other tax returns could adversely affect our operating results and financial condition.

We are subject to income taxes in the United States and various foreign jurisdictions, and our domestic and international tax liabilities will be subject to the allocation of expenses in differing jurisdictions. Our future effective tax rates could be subject to volatility or adversely affected by a number of factors, including:

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

expected timing and amount of the release of tax valuation allowances;

expiration of, or detrimental changes in, research and development tax credit laws;

tax effects of stock-based compensation;

costs related to intercompany restructurings;

changes in tax laws, regulations, accounting principles or interpretations thereof;

future earnings being lower than anticipated in countries where we have lower statutory tax rates and higher than anticipated earnings in countries where we have higher statutory tax rates. or

examinations by US federal, state or foreign jurisdictions that disagree with interpretations of tax rules and regulations in regards to positions taken on tax filings

Changes in our effective tax rate could adversely affect our results of operations.

As our business grows, we are required to comply with increasingly complex taxation rules and practices. We are subject to tax in multiple U.S. tax jurisdictions and in foreign tax jurisdictions as we expand internationally. The development of our tax strategies requires additional expertise and may impact how we conduct our business. Our future effective tax rates

50


could be unfavorably affected by changes in, or interpretations of, tax rules and regulations in the jurisdictions in which we do business, lapses of the availability of the U.S. research and development tax credit or changes in the valuation of our deferred tax assets and liabilities. Furthermore, we provide for certain tax liabilities that involve significant judgment. We are subject to the examination of our tax returns by federal, state and foreign tax authorities, which could focus on our intercompany transfer pricing methodology as well as other matters. If our tax strategies are ineffective or we are not in compliance with domestic and international tax laws, our financial position, operating results and cash flows could be adversely affected.

Our business is subject to the risks of warranty claims, product returns, product liability, and product defects.

Real or perceived errors, failures or bugs in our products could result in claims by end-customers for losses that they sustain. If end-customers make these types of claims, we may be required, or may choose, for customer relations or other reasons, to expend additional resources in order to help correct the problem. Historically, the amount of warranty claims has not been significant, but there are no assurances that the amount of such claims will not be material in the future. Liability provisions in our standard terms and conditions of sale, and those of our resellers and distributors, may not be enforceable under some circumstances or may not fully or effectively protect us from customer claims and related liabilities and costs, including indemnification obligations under our agreements with resellers, distributors or end-customers. The sale and support of our products also entail the risk of product liability claims. We maintain insurance to protect against certain types of claims associated with the use of our products, but our insurance coverage may not adequately cover any such claims. In addition, even claims that ultimately are unsuccessful could result in expenditures of funds in connection with litigation and divert management’s time and other resources.

We are exposed to the credit risk of our distribution channel partners and end-customers, which could result in material losses and negatively impact our operating results.

Most of our sales are on an open credit basis, with typical payment terms ranging from 30 to 90 days depending on local customs or conditions that exist in the sale location. If any of the distribution channel partners or end-customers responsible for a significant portion of our revenue becomes insolvent or suffers a deterioration in its financial or business condition and is unable to pay for our products, our results of operations could be harmed.

Concentration of ownership among our existing executive officers, a small number of stockholders, directors and their affiliates may prevent new investors from influencing significant corporate decisions.

Our executive officers and directors, together with affiliated entities, hold 33% of our outstanding common stock as of September 30, 2015. Accordingly, these stockholders, acting together, have significant influence over the election of our directors, over whether matters requiring stockholder approval are approved or disapproved and over our affairs in general. The interests of these stockholders could conflict with your interests. These stockholders may also have an interest in pursuing acquisitions, divestitures, financings or other transactions that, in their judgment, could enhance their investments, even though such transactions might involve risks to you. In addition, this concentration of ownership could have the effect of delaying or preventing a liquidity event such as a merger or liquidation of our company.

We may need to raise additional funds in future private or public offerings, and such funds may not be available on acceptable terms, if at all. If we do raise additional funds, existing stockholders will suffer dilution.

We may need to raise additional funds in private or public offerings, and these funds may not be available to us when we need them or on acceptable terms, if at all. If we raise additional funds through further issuances of equity or convertible debt securities, you could suffer significant dilution, and any new equity securities we issue could have rights, preferences and privileges superior to those of our then-existing capital stock. Any debt financing secured by us in the future could involve restrictive covenants relating to our capital raising activities and other financial and operational matters, which may make it more difficult for us to obtain additional capital and to pursue business opportunities. If we cannot raise additional funds when we need them, our business and prospects could fail or be materially and adversely affected.

The price of our common stock may be volatile, and the value of your investment could decline.

Technology stocks have historically experienced high levels of volatility. The trading price of our common stock following the initial public offering has fluctuated substantially. Following the completion of the initial public offering, the market price of our common stock has been higher or lower than the price you paid in the offering, depending on many factors, some of which are beyond our control and may not be related to our operating performance. These fluctuations could cause you to lose all or part of your investment in our common stock. Factors that could cause fluctuations in the trading price of our common stock include the following:

51



announcements of new products, services or technologies, commercial relationships, acquisitions or other events by us or our competitors;

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;

fluctuations in the trading volume of our shares or the size of our public float;

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

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

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

litigation or investigations involving us, our industry, or both;

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

general economic conditions and trends;

major catastrophic events;

sales of large blocks of our common stock; or

departures of key personnel.

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, results of operations 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. The price of our common stock has been highly volatile since our IPO in March 2014, and beginning in January 2015, several substantially identical law suits alleging violations of securities laws were filed against us, our directors and certain of our executive officers. These and any future securities litigation, including any related to shareholder derivative litigation, could result in substantial costs and divert our management’s attention and resources from our business. This could have a material adverse effect on our business, results of operations and financial condition.

Sales of substantial amounts of our common stock in the public markets, or the perception that such sales might occur, could reduce the price that our common stock might otherwise attain and may dilute your voting power and your ownership interest in us.

Sales of a substantial number of shares of our common stock in the public market, or the perception that such sales could occur, could adversely affect the market price of our common stock and may make it more difficult for you to sell your common stock at a time and price that you deem appropriate. As of September 30, 2015, there were approximately 5.6 million vested and exercisable options to purchase our common stock, in addition to the 63,243,771 common shares outstanding as of such date. All outstanding shares and all shares issuable upon exercise of outstanding and vested options are freely tradable, subject in some cases to volume and other restrictions of Rules 144 and 701 under the Securities Act of 1933, as amended, as well as our insider trading policy. In addition, holders of certain shares of our outstanding common stock, including an aggregate of 9,427,846 shares held by funds affiliated with Summit Partners, L.P. as of September 30, 2015, are entitled to rights with respect to registration of these shares under the Securities Act pursuant to an investors’ rights agreement.

If these holders of our common stock, by exercising their registration rights, sell a large number of shares, they could adversely affect the market price for our common stock. If we file a registration statement for the purposes of selling additional shares to raise capital and are required to include shares held by these holders pursuant to the exercise of their registration rights, our ability to raise capital may be impaired. Sales of substantial amounts of our common stock in the public market, or the perception that these sales could occur, could cause the market price of our common stock to decline.

52



We are an emerging growth company, and any decision on our part to comply only with certain reduced disclosure requirements applicable to emerging growth companies could make our common stock less attractive to investors.

We are an emerging growth company, and, for as long as we continue to be an emerging growth company, we may choose to take advantage of exemptions from various reporting requirements applicable to other public companies but not to “emerging growth companies,” including, but not limited to, not being required to have our independent registered public accounting firm audit our internal control over financial reporting under Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. We could be an emerging growth company for up to five years following the completion of the initial public offering. We will remain an emerging growth company until the earliest of: (a) the last day of the year (i) following the fifth anniversary of the completion of the initial public offering, (ii) in which we have total annual gross revenue of at least $1.0 billion, or (iii) in which we qualify as a large accelerated filer, which means the market value of our common stock that is held by non-affiliates exceeds $700 million as of the prior June 30, or (b) the date on which we have issued more than $1.0 billion in non-convertible debt securities during the prior three-year period. We cannot predict if investors will find our common stock less attractive if we choose to rely on these exemptions. If some investors find our common stock less attractive as a result of any choices to reduce future disclosure, there may be a less active trading market for our common stock and the price of our common stock may be more volatile.

Under the JOBS Act, emerging growth companies can also delay adopting new or revised accounting standards until such time as those standards apply to private companies. We have irrevocably elected not to avail ourselves of this accommodation allowing for delayed adoption of new or revised accounting standards, and, therefore, we will be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies.

The requirements of being a public company increase costs and may divert management attention.

As a reporting company, we are incurring increased legal, accounting and other expenses, including costs associated with SEC reporting and corporate governance requirements. These requirements include compliance with Section 404 and other provisions of the Sarbanes-Oxley Act, as well as rules implemented by the SEC. In addition, our management team is adopting the requirements of being a reporting company. The expenses incurred for reporting and corporate governance purposes are significant. We expect these rules and regulations to substantially increase our legal and financial compliance costs and to make some activities more time-consuming and costly.

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. Additionally, implementation of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, or the Dodd-Frank Act, may also cause us to incur additional costs and subject us to risks if we are unable to fully comply. For instance, the SEC adopted new disclosure requirements in 2012 as part of implementation of the Dodd-Frank Act regarding the use of conflict minerals mined from the Democratic Republic of Congo and adjoining countries and procedures regarding a manufacturer’s efforts to prevent the sourcing of such conflict minerals. The implementation of these requirements could adversely affect our costs and our relationships with customers and suppliers. 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 expense 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, regulatory authorities may initiate legal proceedings against us and our business may be harmed.

The increased costs associated with operating as a reporting company may decrease our net income or increase our net loss, and may require us to reduce costs in other areas of our business or increase the prices of our products or services. Additionally, if these requirements divert our management’s attention from other business concerns, they could have a material adverse effect on our business, financial condition and results of operations.


53


If securities or industry analysts do not publish research or reports about our business, or publish inaccurate or unfavorable research reports about our business, our share price and trading volume could decline.

The market for our common stock, to some extent, depends on the research and reports that securities or industry analysts publish about us or our business. We do not have any control over these analysts. If one or more of the analysts who cover us should downgrade our shares or change their opinion of our shares, our share price would likely decline. If one or more of these analysts should cease coverage of our company or fail to regularly publish reports on us, we could lose visibility in the financial markets, which would cause our share price or trading volume to decline.

Our charter documents and Delaware law could discourage takeover attempts and lead to management entrenchment.

Our restated certificate of incorporation and bylaws contain provisions that could delay or prevent a change in control of our company. These provisions could also make it difficult for stockholders to elect directors that are not nominated by the current members of our board of directors or take other corporate actions, including effecting changes in our management. These provisions include:

a classified board of directors with three-year staggered terms, which could delay the ability of stockholders to change the membership of a majority of our board of directors;

the ability of our board of directors to issue shares of preferred stock and to determine the price and other terms of those shares, including preference and voting rights, without stockholder approval, which could be used to significantly dilute the ownership of a hostile acquirer;

the exclusive right of our board of directors to elect a director to fill a vacancy created by the expansion of our board of directors or the resignation, death or removal of a director, which prevents stockholders from being able to fill vacancies on our board of directors;

a prohibition on stockholder action by written consent, which forces stockholder action to be taken at an annual or special meeting of our stockholders;

the requirement that a special meeting of stockholders may be called only by the chairman of our board of directors, our Chief Executive Officer, our secretary, or a majority vote of our board of directors, which could delay the ability of our stockholders to force consideration of a proposal or to take action, including the removal of directors;

the requirement for the affirmative vote of holders of at least 66-2/3% of the voting power of all of the then-outstanding shares of the voting stock, voting together as a single class, to amend the provisions of our restated certificate of incorporation relating to the issuance of preferred stock and management of our business or our bylaws, which may inhibit the ability of an acquirer to effect such amendments to facilitate an unsolicited takeover attempt;

the ability of our board of directors, by majority vote, to amend the bylaws, which may allow our board of directors to take additional actions to prevent an unsolicited takeover and inhibit the ability of an acquirer to amend the bylaws to facilitate an unsolicited takeover attempt; and

advance notice procedures with which stockholders must comply to nominate candidates to our board of directors or not to propose matters to be acted upon at a stockholders’ meeting, which may discourage or deter a potential acquirer from conducting a solicitation of proxies to elect the acquiror’s own slate of directors or otherwise attempting to obtain control of us.

In addition, as a Delaware corporation, we are subject to Section 203 of the Delaware General Corporation Law. These provisions may prohibit large stockholders, in particular those owning 15% or more of our outstanding voting stock, from merging or combining with us for a certain period of time.

Proceeds received from the sale of our capital stock may be used for general corporate purposes, and we may not use such proceeds effectively.

We completed our public offering in March 2014. The principal purposes of the initial public offering were to raise additional capital, to create a public market for our common stock and to facilitate our future access to the public equity

54


markets. We intend to use the net proceeds that we received in the initial public offering primarily for general corporate purposes, including working capital, sales and marketing activities, research and development activities, general and administrative matters and capital expenditures, and we may use a portion of the net proceeds for the acquisition of, or investment in, business products, services or technologies that complement our business. Accordingly, our management will have broad discretion over the specific use of the net proceeds that we receive in the initial public offering and might not be able to obtain a significant return, if any, on investment of these net proceeds. We cannot assure you that we will use such proceeds effectively. If we do not use the net proceeds that we received in the initial public offering effectively, our business, results of operations and financial condition could be harmed.

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

A significant natural disaster, such as an earthquake, fire, a flood, or 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, our two primary manufacturers are located in Taiwan, which is near major earthquake fault lines and subject to typhoons during certain times of the year. In the event of a major earthquake or typhoon, or other natural or man-made disaster, our manufacturers in Taiwan may face business interruptions, which may impact quality assurance, product costs, and product supply and timing. In the event our or 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 missed financial targets, such as revenue and shipment targets, and our operations could be disrupted, for the affected quarter or quarters. In addition, cyber security attacks, acts of war or terrorism, or other geo-political unrest could cause disruptions in our business or the business of our supply chain, manufacturers, logistics providers, partners, or end-customers or the economy as a whole. Any disruption in the business of our supply chain, manufacturers, logistics providers, partners or end-customers that impacts sales at the end of a quarter could have a significant adverse impact on our quarterly results. All of the aforementioned risks may be further increased if the disaster recovery plans for us and our suppliers prove to be inadequate. To the extent that any of the above should result in delays or cancellations of customer orders, or the delay in the manufacture, deployment or shipment of our products, our business, financial condition and operating results would be adversely affected.

We do not intend to pay dividends for 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 in the future. In addition, our revolving credit facility currently restrict our ability to pay dividends while this facility remains outstanding. As a result, you may only receive a return on your investment in our common stock if the value of our common stock increases.
