EXPLANATORY NOTE

DASAN Zhone Solutions, Inc. (the "Company") is filing this Amendment No. 1 on Form 10-Q/A (this "Form 10-Q/A") to its Quarterly Report on Form 10-Q for the quarter ended September 30, 2016, which was originally filed on November 14, 2016 (the "Original Form 10-Q"), to restate and amend the Company’s previously issued unaudited condensed consolidated financial statements and related financial formation as of, and for the three and nine months ended, September 30, 2016, which were included in the Original Form 10-Q. In addition, this Form 10-Q/A amends certain related disclosures (including amended disclosure relating to our evaluation of our disclosure controls and procedures and the removal of the references to “Not Reviewed” in the unaudited condensed consolidated financial statements and in the headings of tables of financial information), and includes certain expanded disclosures in “Part I - Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations” related to the expected impact of the Merger (defined below).

As previously reported, on September 9, 2016, the acquisition of Dasan Network Solutions, Inc. ("DNS") was consummated through the merger of a wholly owned subsidiary of the Company with and into DNS, with DNS surviving as a wholly owned subsidiary of the Company (the "Merger"). The Merger has been accounted for as a reverse acquisition under which DNS was considered the accounting acquirer of the Company. In connection with the Merger, the Company changed its name from Zhone Technologies, Inc. to DASAN Zhone Solutions, Inc. For periods through September 8, 2016, Zhone Technologies, Inc. is referred to herein as "Legacy Zhone."

As previously disclosed in the Company’s Current Report on Form 8-K filed on February 24, 2017 with the Securities and Exchange Commission (the "SEC"), on February 20, 2017, the Audit Committee of the Company’s Board of Directors concluded, in consultation with management and after informing the Company’s independent registered public accounting firm, that, the incorrect application of generally accepted accounting principles resulted in material misstatements and a restatement of the Company's unaudited condensed consolidated financial statements for the three and nine months ended September 30, 2016. As a result, the Company's unaudited condensed consolidated financial statements for the three and nine months ended September 30, 2016 contained in the Original Form 10-Q should no longer be relied upon. Refer to Note 1 of the Notes to Consolidated Financial Statements for additional information.

To assist in review of this filing, this Form 10-Q/A sets forth the Original Form 10-Q in its entirety; however, this Form 10-Q/A amends and restates only the following Items of the Original Form 10-Q and only with respect to matters affected by the restatement and the associated material weaknesses and certain expanded disclosures related to the expected impact of the Merger: Items 1, 2 and 4 of Part I and Item 1A of Part II. In addition, pursuant to the rules of the SEC, Item 6 of Part II of the Original Form 10-Q has been amended to include currently dated certifications from the Company’s Co-Chief Executive Officers and Chief Financial Officer, as required by Sections 302 and 906 of the Sarbanes-Oxley Act of 2002. Except for the foregoing amended information, this Form 10-Q/A continues to speak as of the date of the Original Form 10-Q and the Company has not updated the disclosure contained herein to reflect events that occurred as of a later date.

The financial results of the Company for the three and nine months ended September 30, 2016 presented in the Original Form 10-Q and this Form 10-Q/A reflect the operating results of DNS and its consolidated subsidiaries for the period commencing on the first day of the applicable period through September 8, 2016 and the operating results of both DNS and Legacy Zhone and their respective consolidated subsidiaries for the period September 9 through September 30, 2016. Such results are compared to the financial results of DNS and its consolidated subsidiaries for the three and nine months ended September 30, 2015. The balance sheet of the Company as of September 30, 2016 includes the fair value of the assets and liabilities of Legacy Zhone as of the effective date of the Merger. Those assets include the fair value of acquired intangible assets and goodwill. Due to the foregoing, the Company’s financial results for the three and nine months ended September 30, 2016 are not comparable to its financial results for the three and nine months ended September 30, 2015. Refer to Notes 1 and 2 of the Notes to Unaudited Condensed Consolidated Financial Statements for additional information.

DASAN ZhoneDZS was incorporated under the laws of the state of Delaware in June 1999. On September 9, 2016, the Company acquired Dasan Network Solutions, Inc. ("DNS") through the merger of a wholly owned subsidiary of the Company with and into DNS, with DNS surviving as a wholly owned subsidiary of the Company (the "Merger"). At the effective time of the Merger, all issued and outstanding shares of capital stock of DNS held by DASAN Networks, Inc. ("DNI") were canceled and converted into the right to receive shares of the Company's common stock in an amount equal to 58% of the issued and outstanding shares of the Company's common stock immediately following the Merger. In connection with the Merger, the Company changed its name from Zhone Technologies, Inc. to DASAN Zhone Solutions, Inc.

The Company’s common stock continues to be traded on the Nasdaq Capital Market, and the Company’s ticker symbol was changed from "ZHNE" to "DZSI" effective September 12, 2016. The Company is headquartered in Oakland, California.

(b)Consolidated SubsidiariesGoing Concern
DetailsThe accompanying condensed consolidated financial statements have been prepared in conformity with generally accepted accounting principles in the United States ("U.S. GAAP"), assuming the Company will continue as a going concern, which contemplates the realization of assets and satisfaction of liabilities in the normal course of business. Accordingly, the condensed consolidated financial statements do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classification of liabilities that may result from the possible inability of the Company's consolidated subsidiariesCompany to continue as a going concern.
The Company has incurred significant losses to date and losses from operations may continue. The Company incurred net losses of $4.4 million and $15.3 million for the six months ended June 30, 2017 and for the year ended December 31, 2016, respectively. The Company had accumulated deficit of $24.5 million and working capital of $55.2 million as of SeptemberJune 30, 20162017. As of June 30, 2017, the Company had approximately $9.9 million in cash and December 31, 2015cash equivalents, which included $0.9 million in cash balances held by the Company's Korean subsidiary, and $27.0 million in aggregate principal amount of outstanding borrowings under the Company's short-term debt obligations and the Company's loans from DNI and its affiliates. In addition, the Company had $4.1 million in aggregate borrowing availability under its revolving credit facilities as of June 30, 2017. The Company had $8.6 million committed as security for letters of credit under these facilities as of June 30, 2017. Due to the amount of short-term debt obligations maturing within the next 12 months and the Company's recurring operating losses, the Company's cash resources may not be sufficient to settle these short-term debt obligations. The Company's ability to continue as a “going concern” is dependent on many factors, including, among other things, its ability to comply with the covenants in its existing debt agreements, its ability to cure any defaults that occur under its debt agreements or to obtain waivers or forbearances with respect to any such defaults, and its ability to pay, retire, amend, replace or refinance its indebtedness as defaults occur or as interest and principal payments come due. Although the process of amending, replacing or refinancing the Company’s short-term debt obligations is ongoing and the Company is in active discussions with multiple parties, there is no guarantee that they will result in transactions that are sufficient to provide the Company with the required liquidity to remove the substantial doubt as follows:to its ability to continue as a going concern. If the Company is unable to amend, replace or refinance its short-term debt obligations or raise the capital needed to meet liquidity needs and finance capital expenditures and working capital, the Company may experience material adverse impacts on its business, operating results and financial condition.
The Company has continued its focus on cost control and operating efficiency along with restrictions on discretionary spending, however in order to meet the Company's liquidity needs and finance its capital expenditures and working capital needs for its business, the Company may be required to sell assets, issue debt or

equity securities, purchase credit insurance or borrow on potentially unfavorable terms. In addition, the Company may be required to reduce the scope of its planned product development, reduce sales and marketing efforts and reduce its operations in low margin regions, including reductions in headcount. Based on the Company's current plans and business conditions, the Company believes that its focused operating expense discipline along with its existing cash, cash equivalents and available credit facilities will be sufficient to satisfy its anticipated cash requirements for at least the next 12 months, however the factors discussed above raise substantial doubt about the Company's ability to continue as a going concern. The accompanying condensed consolidated financial statements do not include any adjustments that may result from the outcome of the uncertainties set forth above.

(c)Risks and Uncertainties
As result of the Merger, DNI owned approximately 58% of the outstanding shares of the Company's common stock as of June 30, 2017. Thereafter, for so long as DNI and its affiliates hold shares of the Company's common stock representing at least a majority of the votes, DNI will be able to freely nominate and elect all the members of the Company's board of directors. The directors elected by DNI will have the authority to make decisions affecting the Company's capital structure, including the issuance of additional capital stock or options, the incurrence of additional indebtedness, the implementation of stock repurchase programs, and the declaration of dividends. The interests of DNI may not coincide with the interests of the Company's other stockholders or with holders of the Company's indebtedness. DNI’s ability to control all matters submitted to the Company's stockholders for approval limits the ability of other stockholders to influence corporate matters and, as a result, the Company may take actions that the Company's other stockholders or holders of our indebtedness do not view as beneficial. See Note 2, Note 9 and Note 11 to the consolidated financial statements for additional information.
As discussed above in Note 1(b), there is also substantial doubt about the Company's ability to continue as a going concern. The accompanying unaudited consolidated financial statements do not include any adjustments that might be necessary if the Company is unable to continue as a going concern.

(d)Correction of Errors
In this Quarterly Report on Form 10-Q, certain prior quarter financial information has been revised due to correction of certain errors.  The Company identified errors related to the timing of revenue recognition in the consolidated financial statements for the quarter ended June 30, 2016.  Correction of this error resulted in a decrease in total net revenue of $1.1 million, an increase in net loss of $0.6 million and an increase in basic and diluted net loss per share attributable to DZSI of $0.06 for the quarter ended June 30, 2016 as well as a decrease in net revenue of $1.5 million, an increase in net loss of $0.9 million and an increase in basic and diluted net loss per share attributable to DZSI of $0.09 for the six months ended June 30, 2016. The prior quarter financial information has also been revised for the classification of certain related party revenue, related party cost of revenue, and related royalty fees.  This correction resulted in the Company reclassifying revenues of $4.6 million to related party revenues and costs of $3.6 million to related party cost of revenue for the quarter ended June 30, 2016. This further resulted in the Company reclassifying revenues of $9.4 million to related party revenues and costs of $7.5 million to related party cost of revenue for the six months ended June 30, 2016. Finally, an understatement of the cash flows used in investing activities of $0.7 million was corrected in the statement of cashflows for the six months ended June 30, 2016. The overall impact of these errors on the Company's condensed consolidated financial position and results of operations is not material and as such, previously filed quarterly financial information contained in our proxy statement filed with the SEC on August 8, 2016 affected by the errors has not been amended. 

(e)Basis of Presentation
The accompanying unaudited condensed consolidated financial statements are unauditedhave been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements.
The condensed consolidated financial statements reflect all adjustments (consisting only of normal recurring adjustments) that, in the opinion of management, are necessary for a fair presentation of the results for the interim periods presented in accordance with accounting principles generally accepted in the United States of America ("GAAP").presented. All significant inter-companyintercompany transactions and balances have been eliminated in consolidation. The results of operations for the current interim period are not necessarily indicative of results to be expected for the current year or any other period. These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements of the Company and notes thereto included in the

Company’s Annual Report on Form 10-K for the year ended December 31, 2016 filed with the Securities and Exchange Commission.
As discussed more fully in Note 2, on September 9, 2016, the acquisition of Dasan Network Solutions, Inc. ("DNS") was consummated through the Merger of a wholly owned subsidiary of the Company with and into DNS, with DNS surviving as a wholly owned subsidiary of the Company. For periods through September 8, 2016, Zhone Technologies, Inc. is referred to as "Legacy Zhone."
At the effective time of the Merger, all issued and outstanding shares of capital stock of DNS held by DASAN were canceled and converted into the right to receive shares of the Company's common stock in an amount equal to 58% of the issued and outstanding shares of the Company's common stock immediately following the Merger. As a result, immediately following the effective time of the Merger, DASAN held 58% of the outstanding shares of the Company's common stock and the holders of the Company's common stock immediately prior to the Merger retained, in the aggregate, 42% of the outstanding shares of the Company's common stock.
The Merger has been accounted fortreated as a reverse acquisition under whichfor accounting purposes, with DNS was consideredas the accounting acquirer of the Company. As such, the consolidated financial results of the Company for the three and ninesix months ended SeptemberJune 30, 2016 presented in this Form 10-Q/A reflect the operating results of DNS and its consolidated subsidiaries for the period commencing on the first day of the applicable period through September 8, 2016 and the operating results of both DNS and Legacy Zhone and their respective consolidated subsidiaries for the period

September 9 through September 30, 2016. Such results2017 are compared to the financial results offor DNS and its consolidated subsidiaries for the three and ninesix months ended SeptemberJune 30, 2015.2016. The balance sheet of the Company as of September 30, 2016 includesreflects the fair value of the assets and liabilities of Legacy Zhone as of the effective date of the Merger. Those assets include the fair value of acquired intangible assets and goodwill. Due to the foregoing, the Company’s financial results for the three and ninesix months ended SeptemberJune 30, 20162017 are not comparable to its financial results for the three and ninesix months ended SeptemberJune 30, 2015. The fourth quarter ending December 31, 2016 will be the first quarter in which the Company's financial results reflect a full quarter of operating results for both DNS and Legacy Zhone and their respective consolidated subsidiaries.2016.
Except as otherwise specifically noted herein, all references to the "Company" refer to (i) DNS and its consolidated subsidiaries for periods through September 8, 2016 and (ii) the Company and its consolidated subsidiaries for periods on or after September 9, 2016.

(d)Reclassification of Prior Year Presentation
Certain prior year amounts have been reclassified for consistency with the current period presentation. These reclassifications had no effect on the reported results of operations.

(e)(f)Reverse Stock Split
On February 28, 2017, the Company filed a Certificate of Amendment with the Delaware Secretary of State to amend the Company's Restated Certificate of Incorporation, which amendment effected a one-for-five reverse stock split of its common stock. All share and per share information included in the Company's unaudited condensed consolidated financial statementscommon stock and accompanying notes presented herein reflectreduced the retroactive effectauthorized shares of the one-for-fiveCompany's common stock from 180 million to 36 million. As a result of the reverse stock split, as discussed in Note 14.

(f)Risks and Uncertainties
The accompanying condensed consolidated financial statements have been prepared assuming that the Company will continue as a going concern. The Company incurred a net lossnumber of $3.0 million for the year ended December 31, 2015 and a net loss of $8.6 million for the nine months ended September 30, 2016, which net losses have continued to reduce cash and cash equivalents. As of September 30, 2016, the Company had approximately $33.6 million in cash and cash equivalents and $26.9 million in aggregate principal amount of outstanding borrowings under short-term loans and the Company's loan agreement with DASAN. In addition, the Company had an aggregate of $37.0 million in revolving line of credit and letter of credit facilities as of September 30, 2016. The Company had $9.5 million committed as security for letters of credit under these facilities as of September 30, 2016. The $25.0 million revolving line of credit and letter of credit facility with Wells Fargo Bank (the "WFB Facility") contains certain financial covenants, and customary affirmative covenants and negative covenants. See Note 7 and Note 9 for additional information.
The Company’s current lack of liquidity could harm it by:
increasing its vulnerability to adverse economic conditions in its industry or the economy in general;
requiring substantial amounts of cash to be used for debt servicing, rather than other purposes, including operations;
limiting its ability to plan for, or react to, changes in its business and industry; and
influencing investor and customer perceptions about its financial stability and limiting its ability to obtain financing or acquire customers.
In order to meet the Company’s liquidity needs and finance its capital expenditures and working capital needs for the business, the Company may be required to sell assets, issue debt or equity securities, purchase credit insurance or borrow on unfavorable terms. In addition, the Company may be required to reduce its operations in low margin regions, including reductions in headcount. The Company may be unable to sell assets, issue securities or access additional indebtedness to meet these needs on favorable terms, or at all. If additional capital is raised through the issuance of debt securities or other debt financing, the terms of such debt may include covenants, restrictions and financial ratios that may restrict the Company’s ability to operate its business. Likewise, any equity financing could result in additional dilutionshares of the Company’s stockholders. Ifcommon stock then issued and outstanding was reduced from approximately 81.9 million to approximately 16.4 million. References to shares of the Company is unable to sell assets, issue securities or access additional indebtedness to meet these needsCompany's common stock, stock options (and associated exercise price) and restricted stock units in this Quarterly Report on favorable terms, or at all, the Company may become unable to pay its ordinary expenses, including its debt service,Form 10-Q are provided on a timely basis and may be required to reduce the scope of its planned product development and sales and marketing efforts beyond the reductions it has previously taken. Based on the Company’s current plans and business conditions, it believes that its focused

operating expense discipline along with its existing cash, cash equivalents and available credit facilities will be sufficient to satisfy its anticipated cash requirements for at least the next twelve months.
The Company's financial condition and results of operations could be materially and adversely affected by various factors, including:
Potential deferment of purchases and orders by customers;
Customers’ inability to obtain financing to make purchases from the Company and/or maintain their business;
Negative impact from increased financial pressures on third-party dealers, distributors and retailers;
Intense competition in the communication equipment market;
Commercial acceptance of the Company’s products; and
Negative impact from increased financial pressures on key suppliers.
The Company may experience material adverse impacts on its business, operating results and financial condition as a result of weak or recessionary economic or market conditions in the United States, Korea or the rest of the world.post-reverse stock split basis.

(g)Restatement of Previously Reported Consolidated Financial Statements
The Company has determined that the incorrect application of generally accepted accounting principles, resulted in material misstatements and a restatement of the Company's unaudited condensed consolidated financial statements for the three and nine months ended September 30, 2016. The Company concluded that the impact of the errors was immaterial to the unaudited condensed consolidated financial statements for the quarter ended September 30, 2015, except for the impact relating to the error in not calculating EPS by retroactively adjusting the weighted average shares for the impact from the Merger.

The following schedules reconcile the amounts as previously reported in the unaudited condensed consolidated financial statements for the three and nine months ended September 30, 2016 to the corresponding restated amounts (in thousands, except per share data):

(2) The Company did not appropriately classify restricted cash of $0.9 million separately from cash and cash equivalents as of December 31, 2015. The Company has corrected for this error as cumulative adjustment as of September 30, 2016. Management has concluded that this is not material to the current or prior period.

In addition, certain disclosures included in the unaudited condensed consolidated financial statements previously filed were also restated. These disclosures in this Form 10Q/A include schedules reconciling the amounts previously reported to the corresponding restated amounts in their respective sections.

(h)Use of Estimates
The preparation of the condensed consolidated financial statements in conformity with generally accepted accounting principles in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ materially from those estimates.

(i)Revenue Recognition
The Company recognizes revenue when the earnings process is complete. The Company recognizes product revenue upon shipment of product under contractual terms which transfer title to customers upon shipment, under normal credit terms, net of estimated sales returns and allowances at the time of shipment. Revenue is deferred if there are significant post-delivery obligations or if the fees are not fixed or determinable. When significant post-delivery obligations exist, revenue is deferred until such obligations are fulfilled. The Company’s arrangements generally do not have any significant post-delivery obligations. If the Company’s arrangements include customer acceptance provisions, revenue is recognized upon obtaining the signed acceptance certificate from the customer, unless the Company can objectively demonstrate that the delivered products or services meet all the acceptance criteria specified in the arrangement prior to obtaining the signed acceptance. In those instances where revenue is recognized prior to obtaining the signed acceptance certificate, the Company uses successful completion of customer testing as the basis to objectively demonstrate that the delivered products or services meet all the acceptance criteria specified in the arrangement. The Company also considers historical acceptance experience with the customer, as well as the payment terms specified in the arrangement, when revenue is recognized prior to obtaining the signed acceptance certificate. When collectability is not reasonably assured, revenue is recognized when cash is collected.
The Company makes certain sales to product distributors. These customers are given certain privileges to return a portion of inventory. Return privileges generally allow distributors to return inventory based on a percent of purchases made within a specific period of time. The Company recognizes revenue on sales to distributors that have contractual return rights when the products have been sold by the distributors, unless there is sufficient customer specific sales and sales returns history to support revenue recognition upon shipment. In those instances when revenue is recognized upon shipment to distributors, the Company uses historical rates of return from the distributors to provide for estimated product returns.
The Company derives revenue primarily from stand-alone sales of its products. In certain cases, the Company’s products are sold along with services, which include education, training, installation, and/or extended warranty services. As such, some of the Company’s sales have multiple deliverables. The Company’s products and services qualify as separate units of accounting and are deemed to be non-contingent deliverables as the Company’s arrangements typically do not have any significant performance, cancellation, termination and refund type provisions. Products are typically considered delivered upon shipment. Revenue from services is recognized ratably over the period during which the services are to be performed.
For multiple deliverable revenue arrangements, the Company allocates revenue to products and services using the relative selling price method to recognize revenue when the revenue recognition criteria for each deliverable are met. The selling price of a deliverable is based on a hierarchy and if the Company is unable to establish vendor-specific objective evidence of selling price (“VSOE”) it uses third-party evidence of selling price (“TPE”), and if no such data is available, it uses a best estimated selling price (“BSP”). In most instances, particularly as it relates to products, the Company is not able to establish VSOE for all deliverables in an arrangement with multiple elements. This may be due to infrequently selling each element separately, not pricing products within a narrow range, or only having a limited sales history. When VSOE cannot be established, the Company attempts to establish the selling price of each element based on TPE. Generally, the Company’s marketing strategy differs from that of the Company’s peers and the Company’s offerings contain a significant level of customization and differentiation such that the comparable pricing of products with similar functionality cannot be obtained. Furthermore, the Company is unable to reliably determine what similar competitor products’ selling prices are on a stand-alone basis. Therefore, the Company is typically not able to determine TPE for the Company’s products.
When the Company is unable to establish selling price using VSOE or TPE, the Company uses BSP. The objective of BSP is to determine the price at which the Company would transact a sale if the product or service were sold on a stand-alone basis. The BSP of each deliverable is determined using average discounts from list price from historical sales transactions or cost plus margin approaches based on the factors, including but not limited to, the Company’s gross margin objectives and pricing practices plus customer and market specific considerations.
The Company has established TPE for its training, education and installation services. TPE is determined based on competitor prices for similar deliverables when sold separately. These service arrangements are typically short term in nature and are largely completed shortly after delivery of the product. Training and education services are based on a daily rate per person and vary according to the type of class offered. Installation services are based on daily rate per person and vary according to the complexity of the products being installed.

Extended warranty services are priced based on the type of product and are sold in one to five year durations. Extended warranty services include the right to warranty coverage beyond the standard warranty period. In substantially all of the arrangements with multiple deliverables pertaining to arrangements with these services, the Company has used and intends to continue using VSOE to determine the selling price for the services. The Company determines VSOE based on its normal pricing practices for these specific services when sold separately.
(j)Fair Value of Financial Instruments
As of September 30, 2016 and December 31, 2015, the Company's financial instruments included cash and cash equivalents, short-term investments, trade and other receivables, other current assets, accounts payable, other current liabilities and debt. Due to the short-term maturities of cash and cash equivalents, trade and other receivables, other current assets, accounts payable and other current liabilities, the carrying amounts approximate fair value at the applicable balance sheet date. The carrying value of debt approximated its fair value based on a comparison with then-prevailing market interest rates. Due to the short-term maturities of the Company’s investments, carrying amounts approximated fair value at the applicable balance sheet date. The fair value of these instruments would be categorized as Level 2 in the fair value hierarchy, with the exception of cash and cash equivalents, which would be categorized as Level 1.

(k)Concentration of Risk
The Company’s customers include competitive and incumbent local exchange carriers, competitive access providers, Internet service providers, wireless carriers and resellers serving these markets. The Company performs ongoing credit evaluations of its customers and generally does not require collateral. Allowances are maintained for potential doubtful accounts. For the three months ended SeptemberJune 30, 2016 and 2015, three2017, two customers represented 55%11% and 63%14% (a related-party) of net revenue, respectively. For the ninethree months ended SeptemberJune 30, 2016, and 2015, three customers represented 48%34%, 21% (a related-party) and 55%12% of net revenue, respectively. SK Broadband, LG UplusFor the six months ended June 30, 2017, one customer represented 12% (a related-party) of net revenue. For the six months ended June 30, 2016, three customers represented 25%, 23% (a related-party) and DASAN (a related party) each accounted for more than 10%12% of net revenue, for therespectively.
As of June 30, 2017, three months ended September 30, 2016. SK Broadband, LG Uplus, Viettel Groupcustomers represented 22%, 14% and DASAN (a related party) each accounted for more than 10% of net revenue for the nine months ended September 30, 2016. LG Uplus, Korea Telecom and SK Broadband each accounted for more than 10% of net revenue for the three months ended September 30, 2015. LG Uplus, Korea Telecom and Viettel Group each accounted for more than 10% of net revenue for the nine months ended September 30, 2015. Each of the foregoing customers was a customer of DNS prior to the Merger. No Legacy Zhone customers and no other DNS customers accounted for more than 10% of net revenue during the three and nine months ended September 30, 2016 and 2015.
Three customers accounted for 37% and 66%12% of net accounts receivable, asrespectively. The customers who represented 22% and 12% were related parties. As of SeptemberDecember 31, 2016, two customers represented 13% (a related-party) and 10% of net accounts receivable, respectively.
As of June 30, 20162017 and December 31, 2015, respectively.
As of September 30, 2016, and December 31, 2015, receivables from customers in countries other than the United States represented 86%88% and 93%87%, respectively, of net accounts receivable.
(l)Comprehensive Loss
There have been no items reclassified out of accumulated other comprehensive loss and into net loss. The Company’s other comprehensive loss for the three and nine months ended September 30, 2016 and 2015 is comprised of only foreign exchange translation adjustments.

(m)Recent Accounting Pronouncements

On May 28, 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The standard permits the use of either the retrospective or cumulative effect transition method. In August 2015, the FASB issued ASU 2015-14, which defers the effective date of the guidance in ASU No. 2014-09, Revenue from Contracts with Customer, for all entities by one year. With the deferral, the new standard is effective for the Company on January 1, 2018. Early adoption is permitted, but not before the original effective date of January 1, 2017. In May 2016, the FASB issued ASU 2016-12, Revenue from Contracts with Customers, Narrow-Scope Improvements and Practical Expedients, which provides clarification on how to assess collectibility, present sales tax, treat noncash

consideration, and account for completed and modified contracts at the time of transition of ASU 2014-09.

On September 9, 2016, the Company acquired DNS through the Merger of a wholly owned subsidiary of the Company with and into DNS, with DNS surviving as a wholly owned subsidiary of the Company. The Merger combines leading technology platforms with a broadened customer base.


At the effective time of the Merger, all issued and outstanding shares of capital stock of DNS held by DASANDNI were canceled and converted into the right to receive shares of the Company's common stock in an amount equal to 58% of the issued and outstanding shares of the Company's common stock immediately following the Merger. Accordingly, at the effective time of the Merger, the Company issued 9,493,016 shares (post reverse stock split) of the Company’s common stock to DASANDNI as consideration in the Merger, of which 949,302 shares (post reverse stock split) are being held in escrow as security for claims for indemnifiable losses in accordance with the merger agreement relating to the Merger. As a result, immediately following the effective time of the Merger, DASANDNI held 58% of the outstanding shares of the Company's common stock and the holders of the Company's common stock immediately prior to the Merger retained, in the aggregate, 42% of the outstanding shares of the Company's common stock.

As described in Note 1,1(d), the Company accounted for the Merger as a reverse acquisition under the acquisition method of accounting in accordance with ASC 805, "Business Combination." Consequently, for the purpose of the Purchase Price Allocation ("PPA")purchase price allocation, DNS' assets and liabilities have been retained at their carrying values and Legacy Zhone's assets acquired, and liabilities assumed, by DNS (as the accounting acquirer in the Merger) have been recorded at their fair value measured as of September 9, 2016.

The total purchase consideration in the Merger is based on the number of shares of Legacy Zhone common stock and Legacy Zhone stock options vested and outstanding immediately prior to the closing of the Merger, and was determined based on the closing price of $5.95 per share (post reverse stock split) of the Company's common stock on the September 9, 2016 (the effective date of the Merger) and the 6,874,253 shares (post reverse split).2016.

The goodwill was primarily attributed to people, geographic diversification and complementary products. The Goodwillgoodwill arising from the Merger is not tax deductible.

The fair value of the assets acquired included trade receivables of $17.7 million, net of allowances for sales returns and doubtful accounts of $4.6 million.

The Company considered the deferred tax liabilities caused by the Merger to be a source of income to support recoverability of acquired deferred tax assets, before considering the recoverability of the acquirer's existing deferred tax assets. Accordingly, the valuation allowance on the acquiree's deferred tax assets was reduced by the deferred tax liabilities caused by the Merger and accounted for as part of the purchase price allocation.

The Company recorded $1.3 million in Merger-related costs during the three and nine months ended September 30, 2016. These expenses are included in selling, general and administrative expense.

(3) Fair Value Measurement
The Company utilizes a fair value hierarchy that is intended to increase consistency and comparability in fair value measurements and related disclosures. The fair value hierarchy is based on inputs to valuation techniques that are used to measure fair value that are either observable or unobservable. Observable inputs reflect assumptions market participants would use in pricing an asset or liability based on market data obtained from independent sources while unobservable inputs reflect a reporting entity’s pricing based upon their own market assumptions. The fair value hierarchy consists of the following three levels:
(3)Level 1 –CashInputs are quoted prices in active markets for identical assets or liabilities.
Level 2 –Inputs are quoted prices for similar assets or liabilities in an active market, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable and Cash Equivalents and Restricted Cashmarket-corroborated inputs which are derived principally from or corroborated by observable market data.
Level 3 –Inputs are derived from valuation techniques in which one or more significant inputs or value drivers are unobservable.
AsThe following financial instruments are not measured at fair value on the Company’s consolidated balance sheet as of SeptemberJune 30, 20162017 and December 31, 2015, the Company's2016, but require disclosure of their fair values: cash and cash equivalents, comprisedshort-term investments, accounts receivable, accounts payable and debt.

(13)Income Taxes
Income tax expense per the three and six months ended June 30, 2017 was $0.1 million and $0.5 million, respectively, on pre-tax losses of $0.8 million and $3.8 million, respectively. For the three and six months ended June 30, 2016, the Company recognized income tax expense (benefit) of $0.2 million and -$0.4 million, respectively, on pre-tax losses of $0.3 million and $4.7 million, respectively. As of June 30, 2017, the income tax rate varied from the United States statutory income tax rate primarily due to valuation allowances in the United States and taxable income generated by the Company’s wholly-owned foreign subsidiaries.
The total amount of unrecognized tax benefits, including interest and penalties, at SeptemberJune 30, 20162017 was not material. The amount of tax benefits that would impact the effective income tax rate, if recognized, is not expected to be material. There were no significant changes to unrecognized tax benefits during the threequarters ended June 30, 2017 and nine months ended September 30, 2016 and 2015.2016. The Company does not anticipate any significant changes with respect to unrecognized tax benefits within the next 12 months.

The Company or one of its subsidiaries files income tax returns in the U.S. federal jurisdiction, and various state and foreign jurisdictions. The open tax years for the major jurisdictions are as follows:
•    Federal2012 – 2015
2013 - 2016
•    California and Canada2011 – 2015
2012 - 2016
•    Brazil2010 – 2015
2011 - 2016
•    Germany2008 – 2015
2012 - 2016
•    Japan2011 – 2015
- 2016
•    Korea2014 – 2015
- 2016
•    United Kingdom2014 - 2016
•    Vietnam2011 – 20152016

However, due to the fact the Company had net operating losses and credits carried forward in most jurisdictions, certain items attributable to technically closed years are still subject to adjustment by the relevant taxing authority through an adjustment to tax attributes carried forward to open years.
The Company uses the asset and liability method to account for income taxes. Under this method, deferred tax assets and liabilities are determined based on differences between the financial reporting and the income tax bases of assets and liabilities. Deferred tax assets and liabilities are measured using enacted tax rates and laws that will be in effect when the differences are expected to reverse. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized.
The Company estimates that its foreign income will generally be subject to taxation in the United States on a current basis and that its foreign subsidiaries and representative offices will therefore not have any material untaxed earnings subject to deferred taxes. In addition, to the extent the Company is deemed to have a sufficient connection to a particular taxing jurisdiction to enable that jurisdiction to tax the Company but the Company has not filed an income tax return in that jurisdiction for the year(s) at issue, the jurisdiction would typically be able to assert a tax liability for such years without limitation on the number of years it may examine.

The Company is not currently under examination for income taxes in any material jurisdiction.
The deferred tax liabilities arising from the Merger were applied to the acquiree's deferred tax assets first. Accordingly, the tax benefit arising from those deferred tax liabilities was used to offset the corresponding deferred tax assets as part of the purchase price allocation.
The Company recognizes deferred tax liabilities associated with undistributed earnings of foreign subsidiaries, unless the earnings are expected to be reinvested permanently. Thus, the Company has not recorded deferred taxes on undistributed earnings, as they are intended to be permanently reinvested. If circumstances change and it becomes apparent that some or all of the undistributed earnings will not be invested indefinitely, or will be remitted in the foreseeable future, an additional deferred tax liability will be recorded for some or all of the undistributed earnings.

OVERVIEW

We are a global leader in broad-basedprovider of network access solutions.solutions and communications equipment for service provider and enterprise networks. We provide solutionsresearch, develop, test, sell, manufacture and support communications equipment in five major product areas: broadband access, Ethernet switching, mobile backhaul, passive optical LAN (POLAN) and software defined networks (SDN).

As discussed under "Liquidity and Capital Resources" below, the maturing of short-term debt obligations and our recurring losses from operations raise substantial doubt on whether we will be able to continue as a going concern.
Broadband AccessAs of June 30, 2017, the total outstanding principal amount of our debt obligations was $27.0 million, consisting of the following:

$16.7 million in short-term debt obligations;
$5.3 million in short-term debt obligations to related parties; and
$5.0 million in long-term debt obligations to related parties.
Our broadband access products offerability to continue as a variety of options for carriers“going concern” is dependent on many factors, including, among other things, our ability to comply with the covenants in our existing debt agreements, our ability to cure any defaults that occur under our debt agreements or to obtain waivers or forbearances with respect to any such defaults, and service providersour ability to connect residentialpay, retire, amend, replace or refinance our indebtedness as defaults occur or as interest and business customers. Our solutions allow carriers and service providers to either use high-speed fiber or leverage their existing deployed copper networks to offer broadband services to customer premises. Once our broadband access products are deployed, the service provider can offer voice, high-definition and ultra-high-definition video, high-speed internet access and business class services to their customers. We develop our broadband access products for all aspects of carrier and service provider access networks: customer premise equipment (such as DSL modems), Ethernet access demarcation devices, Gigabit passive optical network (GPON) and Gigabit Ethernet passive optical network (GEPON) optical network terminals (ONTs). We also develop central office products, such as broadband loop carriers for digital subscriber lines (DSL) and voice-grade telephone service (POTS), high-speed digital subscriber line access multiplexers (DSLAMs) with G.fast and very-high-bit-rate DSL (VDSL) capabilities, optical line terminals (OLTs) for passive optical distribution networks like GPON and GEPON as well as point-to-point Ethernet service for 1 Gigabit to 10 Gigabit access. Both DNS and Legacy Zhone were market leaders in the broadband access market prior to the Merger, and the combination of DNS and Legacy Zhone is expected to enhance our leadership position for both carrier and enterprise solutions in this market following the Merger.

Ethernet Switching

Our Ethernet switching products provide a high-performance and manageable solution that bridges the gap from carrier access technologies to the core network. Over the past ten years carriers have migrated access infrastructure to Ethernet from time-division multiplexing and asynchronous transfer mode systems. Our products can also be deployed in data centers, blurring the line between central office and data center. Our products support pure Ethernet switching as well as layer 3 IP and MPLS capabilities, and are currently being developed for interfacing with SDNs. Legacy Zhone did not offer comparable Ethernet switching products prior to the Merger, and therefore the Ethernet switching market is expected to provide an opportunity for growth for the combined company following the Merger.

Mobile Backhaul

Our mobile backhaul products provide a robust, manageable and scalable solution for mobile operators that enable them to upgrade their mobile backhaul systems and migrate from 3G networks to LTE and beyond. We provide our mobile backhaul products to mobile operators or carriers who provide the transport for mobile operators. Our mobile backhaul products may be collocated at the radio access node (RAN) base station (BS) and can aggregate multiple RAN BS in to a single backhaul for delivery of mobile traffic to the RAN network controller. We provide standard Ethernet/IP or multiprotocol label switching (MPLS) interfaces and interoperate with other vendors in these networks. With mobile backhaul networks providing carriers with significant revenue growth in recent years, mobile backhaul has become one of the most important parts of their networks. Legacy Zhone did not offer comparable mobile backhaul products prior to the Merger, and therefore the mobile backhaul market is expected to provide an opportunity for growth for the combined company following the Merger.

Passive Optical LAN

Our FiberLAN portfolio of POLAN products are designed for enterprise, campus, hospitality, and entertainment arena usage. Our FiberLAN portfolio includes our high-performance, high-bandwidth GPON OLTs connected to the industry’s most diverse ONT product line, which include units with integrated Power over Ethernet (PoE) to power a wide range of devices such as our full range of WIFI access points (APs) and scalable WIFI AP controller. Our environmentally friendly FiberLAN POLAN solutions are one of the most cost effective LAN technologies that can be deployed, allowing network managers to deploy a future proof, low-maintenance, manageable solution that requires less space, air conditioning, copper and electricity than other alternatives. Our FiberLAN portfolio relates primarily to Legacy Zhone products, while our WIFI access points and controllers consist primarily of DNS products. We expect the combination of Legacy Zhone and DNS products in this market to enhance the functionality of our product offerings and provide an opportunity for growth for the combined company following the Merger.


Software Defined Networks

Our SDN and network function virtualization (NFV) tools and building blocks to allow service providers to migrate their networks’ full complement of legacy control plane and data plane devices to a centralized intelligent controller that can reconfigure the services of the hundreds of network elements in real time for more controlled and efficient provision of bandwidth and latency across the network. This move to SDN and NFV provides better service for end customers and a more efficient and cost-effective use of hardware resources for service providers. We leverage our broadband access, mobile backhaul and Ethernet switching expertise to extract and virtualize many of the traditional legacy control and data plane functions to allow them to be run from the cloud. The latest evolution of our hardware-based solution was designed to support SDN and NFV. Our SDN and NFV tools reflect the combined experience and technologies of DNS and Legacy Zhone.

We have incurred significant losses to date and expect that our operating losses and negative cash flows from operations may continue. We incurred a net loss of $3.0 million for the year ended December 31, 2015 and a net loss of $8.6 million for the nine months ended September 30, 2016, which net losses have continued to reduce cash and cash equivalents. We had an accumulated deficit of $12.8 million as of September 30, 2016. If we are unable to access or raise the capital needed to meet liquidity needs and finance capital expenditures and working capital, or if the economic, market and geopolitical conditions in the United States, Korea and the rest of the world deteriorate, we may experience material adverse impacts on our business, operating results and financial condition. We have continued our focus on cost control and operating efficiency along with restrictions on discretionary spending.principal payments come due.
Going forward, our key financial objectives include the following:
Increasing revenue while continuing to carefully control costs;
Continued investments in strategic research and product development activities that will provide the maximum potential return on investment; and
Minimizing consumption of our cash and cash equivalents.
MERGERMerger
On September 9, 2016, we acquired DNS through the merger of a wholly owned subsidiary of Zhone Technologies, Inc. with and into DNS, with DNS surviving as our wholly owned subsidiary (the Merger). In connection with the Merger, Zhone Technologies, Inc. changed its name to DASAN Zhone Solutions, Inc. Our common stock continues to be traded on the Nasdaq Capital Market, and our ticker symbol was changed from "ZHNE" to "DZSI" effective September 12, 2016.
At the effective time of the Merger, all issued and outstanding shares of capital stock of DNS held by its sole shareholder, DASAN Networks, Inc. (DASAN)(DNI), were canceled and converted into the right to receive shares of our common stock in an amount equal to 58% of the issued and outstanding shares of our commonscommon stock immediately following the Merger. Accordingly, at the effective time of the Merger, we issued 9,493,016 shares (post reverse stock split) of our common stock to DASANDNI as consideration in the Merger, of which 949,302 shares (post reverse stock split) are being held in escrow as security for claims for indemnifiable losses in accordance with the merger agreement relating to the Merger. As a result, immediately following the effective time of the Merger, DASANDNI held 58% of the outstanding shares of our common stock and the holders of our common stock immediately prior to the Merger retained, in the aggregate, 42% of the outstanding shares of our common stock.
See Note 2 to the unaudited condensed consolidated financial statements set forth in Part I, Item 1 of this report for additional information regarding the Merger.

ITEMS AFFECTING COMPARABILITY OF OUR FINANCIAL RESULTS
As discussed in Note 11(e) to the unaudited condensed consolidated financial statements set forth in Part I, Item 1 of this report, the Merger has been accounted for as a reverse acquisition under which DNS was considered the accounting acquirer of Legacy Zhone. As such, our financial results for the three and ninesix months ended SeptemberJune 30, 20162017 presented in this Form 10-Q/A reflect the operating results of DNS and its consolidated subsidiaries for the period commencing on the first day of the applicable period through September 8, 2016 and the operating results of both DNS and Legacy Zhone and their respective consolidated subsidiaries for the period September 9 through September 30, 2016. Such resultsreport are compared to the financial results of DNS and its consolidated subsidiaries for the three and ninesix months ended SeptemberJune 30, 2015.2016. Our balance sheet as of September 30, 2016 includes the fair value of the assets and

liabilities of Legacy Zhone as of the effective date of the Merger. Those assets include the fair value of acquired intangible assets and goodwill. Due to the foregoing, our financial results for the three and ninesix months ended SeptemberJune 30, 20162017 are not comparable to our financial results for the three and ninesix months ended SeptemberJune 30, 2015. The fourth quarter ending December 31, 2016 will be the first quarter in which our financial results reflect a full quarter of operating results for both DNS and Legacy Zhone and their respective consolidated subsidiaries.2016.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

There have been no material changes to our critical accounting policies and estimates from the critical accounting policiesinformation provided in Part II, “Item 7. Management’s Discussion and estimatesAnalysis of DNS set forth in the consolidated financial statementsFinancial Condition and Results of DNSOperations – Critical Accounting Policies and the notes thereto and elsewhereEstimates” included in our Definitive Proxy Statement filed withAnnual Report on Form 10-K for the SEC on August 8, 2016, except for Goodwill and Other Acquisition-Related Intangible Assets as described below.

Goodwill and Other Acquisition-Related Intangible Assets
Goodwill and other acquisition-related intangible assets not subject to amortization are tested annually for impairment using a two-step approach, and are tested for impairment more frequently if events and circumstances indicate that the asset might be impaired. An impairment loss is recognized to the extent that the carrying amount exceeds the asset’s fair value. In the application of the impairment testing, we are required to make estimates of future operating trends and resulting cash flows and judgments on discount rates and other variables. Actual future results and other assumed variables could differ from these estimates.   Our future operating performance will be impacted by the future amortization of intangible assets, potential charges related to purchased in-process research and development for future acquisitions, and potential impairment charges related to goodwill. Accordingly, the allocation of the purchase price of the acquired companies to intangible assets and goodwill has a significant impact on our future operating results. The allocation process requires management to make significant estimates and assumptions, including estimates of future cash flows expected to be generated by the acquired assets and the appropriate discount rate for these cash flows. Should different conditions prevail, we would have to perform an impairment review that might result in material write-downs of intangible assets and/or goodwill. Other factors we consider important which could trigger an impairment review, include, but are not limited to, significant changes in the manner of use of our acquired assets, significant changes in the strategy for our overall business or significant negative economic trends. If this evaluation indicates that the value of an intangible asset may be impaired, an assessment of the recoverability of the net carrying value of the asset over its remaining useful life is made. If this assessment indicates that the cost of an intangible asset is not recoverable, based on the estimated undiscounted future cash flows or other comparable market valuations of the entity or technology acquired over the remaining amortization, the net carrying value of the related intangible asset will be reduced to fair value and the remaining amortization period may be adjusted.  Due to uncertain market conditions and potential changes in our strategy and product portfolio, it is possible that forecasts used to support our intangible assets may change in the future, which could result in additional non-cash charges that would adversely affect our results of operations and financial condition.

Net Revenue
Prior to the Merger, DNS was a leading telecommunications equipment provider in the Asia-Pacific region, providing products and services to some of the largest carriers in the region with a particular focus on Korea, Japan and Vietnam. DNS typically generated approximately 85% of its net revenue from the Asia-Pacific region prior to the Merger. In contrast, Legacy Zhone typically generated less than 5% of its net revenue from the Asia-Pacific region prior to the Merger, with instead the majority of its net revenue derived from the Americas and the EMEA region. Given DNS’ pre-Merger market share in Korea and in the Asia-Pacific region generally, we expect that net revenue from Korea and elsewhere in the Asia-Pacific region will continue to be significant for the combined company following the Merger, with growth opportunities for the combined company to expand sales of legacy DNS products in the geographic regions where Legacy Zhone had a strong presence.

For the nine months ended September 30, 2016, product revenue decreased 3% or $2.4 million to $86.5 million, compared to $88.9 million for the same period last year. The increase in net revenue for the three and six months ended SeptemberJune 30, 20162017 was primarily related to the consummation of the Merger in September 2016 (which resulted in the inclusion of net revenue related to the Legacy Zhone business for 22 days of the current year quarter)periods). The relatively flat net revenues for the nine months ended September 30 2016 compared to the prior year period was primarily attributable to decreased sales in the Korea, offset by the inclusion of net revenue related to the Legacy Zhone business for 22 days of the current year period.
Service revenue mainly represents revenue from service maintenance contracts.and other services associated with product shipments. For the three months ended SeptemberJune 30, 2016 and 2015,2017, service revenue increased 1,100%108% or $2.2$1.4 million to $2.3$2.7 million compared to $0.2 million for the same period last year.

The increaseincreases in service revenue for the three and nine months ended September 30, 2016 waswere primarily related to the consummation of the Merger in September 2016 (which resulted in the inclusion of service revenue related to the Legacy Zhone business for 22 days of the current year period)periods), as well as an increase in sales of maintenance services.
International net revenue increased 14%43% or $3.2$14.0 million to $25.3$46.6 million for the three months ended SeptemberJune 30, 20162017 from $22.1$32.6 million for the same period last year, and represented 79%78% of total net revenue compared with 98%95% during the same period of 2015.2016.

The decrease in international net revenue for the nine months ended September 30, 2016 compared to the prior year period was primarily due to decreased sales in Korea, partially offset by the inclusion of net revenue related to the Legacy Zhone business for 22 days of the current year period.

No Legacy Zhone customers and no other DNS customers accounted for more than 10% of net revenue during the three and nine months ended September 30, 2016 and 2015.
respectively. We anticipate that our results of operations in any given period may depend to a large extent on sales to a small number of large accounts. As a result, our revenue for any quarter may be subject to significant volatility based upon changes in orders from one or a small number of key customers.
Cost of Revenue and Gross Margin
Total cost of revenue including stock-based compensation and amortization of intangibles, increased 34%61% or $5.8$15.5 million to $22.6$40.8 million for the three months ended SeptemberJune 30, 2016,2017, compared to $16.8$25.3 million for the three months ended SeptemberJune 30, 2015.2016. Total cost of revenue including stock-based compensation and amortization of intangibles slightly decreased 0.6%increased 63% or $0.4$29.1 million to $68.9$75.1 million for the ninesix months ended SeptemberJune 30, 20162017, compared to $69.3$46.0 million for the same period last year.six months ended June 30, 2016. The increaseincreases in total cost of revenue for the three months ended September 30, 2016 waswere primarily due to the consummation of the Merger in September 2016 (which resulted in the inclusion of cost of revenue related to the Legacy Zhone business for 22 days of the current year period)periods) as well as increased sales in the current year period.sales. Gross margin increased slightly increasedin both the three and six months ended June 30, 2017 compared to the prior year periods due to improved manufacturing efficiencies and product mix.
We expect that in the future our cost of revenue as a percentage of net revenue will vary depending on the mix and average selling prices of products sold, with longer term gross margin expansion expected to come from product cost reductions and manufacturing economies of scale resulting from the Merger.sold. In addition, continued competitive and economic pressures could cause us to reduce our prices, adjust the carrying values of our inventory, or record inventory charges relating to discontinued products and excess or obsolete inventory.

Research and Product Development Expenses
Research and product development expenses increased 21%79% or $1.0$4.0 million to $5.9$9.0 million for the three months ended SeptemberJune 30, 20162017 compared to $4.9$5.0 million for the three months ended SeptemberJune 30, 2015.2016. Research and product development expenses decreased 6%increased 88% or $1.0$8.5 million to $15.6$18.2 million for the ninesix months ended SeptemberJune 30, 20162017 compared to $16.5$9.7 million for the same period last year.six months ended June 30, 2016. The increase in research and product development expenses for the three months ended September 30, 2016 was primarily due to the consummation of the Merger in September 2016 (which resulted in the inclusion of research and product development expenses related to the Legacy Zhone business for 22 days of the current year period. The decrease in research and product development expenses for the nine months ended September 30, 2016 was primarily due to a reduction in personnel-related expenses from lower headcount as compared to the same period last year, partially offset by the inclusion of research and product development expenses relating to the Legacy Zhone business in the current year period as a result of the consummation of the Merger in September 2016.period). We intend to continue to invest in research and product development to attain our strategic product development objectives while seeking to manage the associated costs through expense controls.
Selling, Marketing, General and Administrative Expenses
Selling, marketing, general and administrative expenses increased 110%152% or $4.3$6.3 million to $8.3$10.5 million for the three months ended SeptemberJune 30, 20162017 compared to $3.9$4.1 million for the three months ended SeptemberJune 30, 2015,2016. Selling, marketing, general and administrative expenses increased 36%150% or $4.5$12.6 million to $17.0$21.1 million for the ninesix months ended SeptemberJune 30, 20162017 compared to $12.5$8.4 million for the same period last year.six months ended June 30, 2016. The increases in selling, marketing, general and administrative expenses were primarily due to the consummation of the Merger in September 2016 (which resulted in the inclusion of selling, marketing, general and administrative expenses related to Legacy Zhone business for 22 days of the current year period)periods), offset by higher commission expenses during the three and inclusion in the current year periods of $1.3 million in Merger-related costs.
We expect selling, general and administrative expenses to increase following the Merger, primarily driven by an increase in sales commission expense resulting from expected additional sales opportunities primarily related to the combined company's mobile backhaul and FiberLAN POLAN products.six months ended June 30, 2016.
Income Tax Provision
During the three and ninesix months ended SeptemberJune 30, 20162017 and 2015,2016, no material provision or benefit for income taxes was recorded, due to our recurring operating losses and the significant uncertainty regarding the realization of our net deferred tax assets, against which we have continued to record a full valuation allowance.

OTHER PERFORMANCE MEASURES
In managing our business and assessing our financial performance, we supplement the information provided by our GAAP results with adjusted earnings before stock-based compensation, interest, taxes, and depreciation, or Adjusted EBITDA, a non-GAAP financial measure. We define Adjusted EBITDA as net income (loss) plus (i) interest expense, (ii) provision (benefit) for taxes, (iii) depreciation and amortization, (iv) Merger-related costsstock-based compensation, and (v) non-cash equity-based compensation expense, and (vi) material non-recurring non-cash transactions or events, such as Merger transaction costs or a gain (loss) on sale of assets or impairment of fixed assets. We believe that the presentation of Adjusted EBITDA enhances the usefulness of our financial information by presenting a measure that management uses internally to monitor and evaluate our operating performance and to evaluate the effectiveness of our business strategies. We believe Adjusted EBITDA also assists investors and analysts in comparing our performance across reporting periods on a consistent basis because it excludes the impact of items that we do not believe reflect our core operating performance.

Adjusted EBITDA has limitations as an analytical tool. Some of these limitations are:
Adjusted EBITDA does not reflect our cash expenditures, or future requirements, for capital expenditures or contractual requirements;
Adjusted EBITDA does not reflect changes in, or cash requirements for, our working capital needs;
Adjusted EBITDA does not reflect the interest expense, or the cash requirements necessary to service interest or principal payments, on our debts;
although depreciation and amortization are non-cash charges, the assets being depreciated and amortized will often have to be replaced in the future, and Adjusted EBITDA does not reflect any cash requirements for such replacements;

non-cash compensation is and will remain a key element of our overall long-term incentive compensation package, although we exclude it as an expense when evaluating our ongoing operating performance for a particular period; and
other companies in our industry may calculate Adjusted EBITDA and similar measures differently than we do, limiting its usefulness as a comparative measure.
Because of these limitations, Adjusted EBITDA should not be considered in isolation or as a substitute for net income (loss) or any other performance measures calculated in accordance with GAAP or as a measure of liquidity. Management understands these limitations and compensates for these limitations by relying primarily on our GAAP results and using Adjusted EBITDA only supplementally.
Set forth below is a reconciliation of net loss to Adjusted EBITDA, which we consider to be the most directly comparable GAAP financial measure to Adjusted EBITDA (in thousands):

LIQUIDITY AND CAPITAL RESOURCES (AS RESTATED)
Our operations are financed through a combination of our existing cash, cash equivalents, available credit facilities, and sales of equity and debt instruments, based on our operating requirements and market conditions.
As of SeptemberJune 30, 20162017, our cash and cash equivalents were $33.69.9 million compared to $10.0$17.9 million at December 31, 2015, which2016. Our cash and cash equivalents as of June 30, 2017 included $24.8$0.9 million in international cash balances.balances held by our Korean subsidiary. The $23.6$8.0 million increasedecrease in cash and cash equivalents was attributable to net cash provided byused in operating investing and financing activities of $13.2 million, $5.3$6.8 million and $3.5$0.9 million, respectively, andpartially offset by the effect of exchange rate changes on cash of $1.6$0.7 million and net cash provided by investing activities of $0.9 million.
Ability to Continue as a Going Concern
The accompanying condensed consolidated financial statements have been prepared in conformity with GAAP, assuming we will continue as a going concern, which contemplates the realization of assets and satisfaction of liabilities in the normal course of business. Accordingly, the condensed consolidated financial statements do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classification of liabilities that may result from the possible inability of DZS to continue as a going concern.
We have incurred significant losses to date and our losses from operations may continue. We incurred net losses of $0.9 million and $15.3 million for the six months ended June 30, 2017 and the year ended December 31, 2016, respectively. We had accumulated deficit of $24.5 million and working capital of $55.2 million as of June 30, 2017. As of June 30, 2017, we had

approximately $9.9 million in cash and cash equivalents, which included $0.9 million in cash balances held by our Korean subsidiary, and $27.0 million in aggregate principal amount of outstanding borrowings under our short-term debt obligations and our loans from DNI and its affiliates. In addition, we had $5.5 million in aggregate borrowing availability under our credit facilities as of June 30, 2017. We had $9.0 million committed as security for letters of credit under these facilities as of June 30, 2017. Due to the amount of short-term debt obligations maturing within the next 12 months and our recurring operating losses, our cash resources may not be sufficient to settle these short-term debt obligations. Our ability to continue as a "going concern" is dependent on many factors, including, among other things, our ability to comply with the covenants in our existing debt agreements, our ability to cure any defaults that occur under our debt agreements or to obtain waivers or forbearances with respect to any such defaults, and our ability to pay, retire, amend, replace or refinance our indebtedness as defaults occur or as interest and principal payments come due. Although the process of amending, replacing or refinancing our short-term debt obligations is ongoing and we are in active discussions with multiple parties, there is no guarantee that they will result in transactions that are sufficient to provide us with the required liquidity to remove the substantial doubt as to our ability to continue as a going concern. If we are unable to amend, replace, refinance our short-term debt obligations or raise the capital needed to meet liquidity needs and finance capital expenditures and working capital, we may experience material adverse impacts on our business, operating results and financial condition.

We have continued our focus on cost control and operating efficiency along with restrictions on discretionary spending. In order to meet our liquidity needs and finance our capital expenditures and working capital needs for our business, we may be required to sell assets, issue debt or equity securities, purchase credit insurance or borrow on potentially unfavorable terms. In addition, we may be required to reduce the scope of our planned product development, reduce sales and marketing efforts and reduce our operations in low margin regions, including reductions in headcount. Based on our current plans and business conditions, we believe that our focused operating expense discipline along with our existing cash, cash equivalents and available credit facilities will be sufficient to satisfy our anticipated cash requirements for at least the next 12 months, however the factors discussed above raise substantial doubt about our ability to continue as a going concern.
Operating Activities
Net cash provided byused in operating activities for the ninesix months ended SeptemberJune 30, 20162017 consisted of a net loss of $8.6$4.4 million, adjusted for non-cash charges totaling $1.9$3.1 million and an increasea decrease in net operating assets totaling $19.9$5.5 million.

Under the WFB Facility, we have the option of borrowing funds at agreed upon interest rates. The amount that we are able to borrow under the WFB Facility varies based on eligible accounts receivable and inventory, as defined in the WFB Facility, as long as the aggregate amount outstanding does not exceed $25.0 million less the amount committed as security for letters of credit. To maintain availability of funds under the WFB Facility, we pay a commitment fee on the unused portion. The commitment fee is 0.25% per annum and is recorded as interest expense.
Based on eligible accounts receivable and inventory, as defined inAs of June 30, 2017, we had no outstanding borrowings under the WFB Facility, weand $2.5 million was committed as security for letters of credit.

These facilities are renewed on an annual basis and are generally secured by a security interest in certain assets of the applicable foreign subsidiaries. Payments under such facilities are made in accordance with the given lender’s amortization schedules. As of SeptemberJune 30, 20162017 and December 31, 2015,2016, we had an aggregate outstanding balance of $20.1$16.7 million and $21.8$17.6 million, respectively, under such financing arrangements, and the interest rate per annum applicable to outstanding borrowings under these financing arrangements as of SeptemberJune 30, 20162017 and December 31, 20152016 ranged from 1.66%2.3% to 4.26%5.9% and 2.04%1.9% to 3.55%4.1%, respectively.
As of September 30, 2016, we had a $12.0 million letter of credit facility with certain foreign banks under which $5.7 million was committed as security for letters of credit.
Related PartyRelated-Party Debt
In connection with the Merger, on September 9, 2016, we entered into a Loan Agreementloan agreement with DASANDNI for a $5.0 million unsecured subordinated term loan facility. Under the Loan Agreement,loan agreement, we were permitted to request drawdowns of one or more term loans in an aggregate principal amount not to exceed $5.0 million. As of SeptemberJune 30, 2016,2017, $5.0 million in term loans was outstanding under the facility. Such term loans mature in September 2021 and are pre-payable at any time by us without premium or penalty. The interest rate as of SeptemberJune 30, 20162017 under this facility was 4.6% per annum.
In addition, DNSwe borrowed $1.8 million from DASANDNI for capital investment in February 2016, which amount was outstanding as of SeptemberJune 30, 2016.2017. This loan maturesmatured in March 2017 with an option of renewal by mutual agreement, and bearsbore interest at a rate of 6.9% per annum, payable annually. Effective February 27, 2017, we amended the terms of this loan to extend the repayment date from March 2017 to March 2018 and to reduce the interest rate from 6.9% to 4.6% per annum.
On June 23, 2017, we borrowed $3.5 million from Solueta, an affiliate of DNI, which amount was outstanding as of June 30, 2017. This loan matures in November 2017 and bears interest at a rate of 4.6% per annum, payable monthly.
Future Requirements and Funding Sources
Our fixed commitments for cash expenditures consist primarily of payments under operating leases, inventory purchase commitments, and payments of principal and interest for debt obligations.
From time to time, we may provide or commit to extend credit or credit support to our customers. This financing may include extending the terms for product payments to customers. Any extension of financing to our customers will limit the capital that we have available for other uses.
Our accounts receivable, while not considered a primary source of liquidity, represent a concentration of credit risk because a significant portion of the accounts receivable balance at any point in time typically consists of a relatively small number of customer account balances. As of SeptemberJune 30, 2016,2017, three customers accounted for 37%22%, 14% and 12% of net accounts receivablereceivables, respectively, and receivables from customers in countries other than the United States represented 86%88% of net accounts receivable. We do not currently have any material commitments for capital expenditures, or any other material commitments aside from operating leases for our facilities, inventory purchase commitments and debt.

We have incurred significant lossesAs discussed above in "Ability to date and expect that our operating losses and negative cash flows from operations may continue. We incurredContinue as a net loss of $3.0 million for the year ended December 31, 2015 and a net loss of $8.6 million for the nine months ended September 30, 2016, which net losses have continued to reduce cash and cash equivalents. We had an accumulated deficit of $12.8 million at September 30, 2016. In order to meet our liquidity needs and finance our capital expenditures and working capital needs for our business, we may be required to sell assets, issue debt or equity securities, purchase credit insurance or borrow on potentially unfavorable terms. In addition, we may be required to reduce our operations in low margin regions, including reductions in headcount. We may be unable to sell assets, issue securities or access additional indebtedness to meet these needs on favorable terms, or at all. If additional capitalGoing Concern", there is raised through the issuance of debt securities or other debt financing, the terms of such debt may include covenants, restrictions and financial ratios that may restrictsubstantial doubt about our ability to operate our business. Likewise,continue as a going concern. The accompanying condensed consolidated financial statements do not include any equity financing could result in additional dilution of our stockholders. Ifadjustments that might be necessary if we are unable to obtain additional capital or are required to obtain additional capital on terms that are not favorable to us, we may be required to reduce the scope of our planned product development and sales and marketing efforts beyond the reductions we have previously taken. Based on our current plans and business conditions, we believe that our focused operating expense discipline along with our existing cash, cash equivalents and available credit facilities will be sufficient to satisfy our anticipated cash requirements for at least the next twelve months.continue as a going concern.


Contractual Commitments and Off-Balance Sheet Arrangements

Operating Leases
The operating lease amounts shown above represent primarily off-balance sheet arrangements. For operating lease commitments, a liability is generally not recorded on our balance sheet unless the facility represents an excess facility for which an estimate of the facility exit costs has been recorded on our balance sheet, net of estimated sublease income. For operating leases that include contractual commitments for operating expenses and maintenance, estimates of such amounts are included based on current rates. Payments made under operating leases will be treated as rent expense for the facilities currently being utilized.
Unrecognized
Purchase Commitments
The unrecognized purchase commitments shown above represent non-cancellable inventory purchase commitments as of SeptemberJune 30, 2016.2017.
Lines of CreditOn July 16, 2017, we reached an agreement with a supplier to cancel a purchase arrangement for certain inventory which was committed through 2020. Under the settlement, we are no longer required to fulfill our commitment to purchase $4.3 million in inventory. In connection with the settlement, we also entered into a technical support services arrangement with the supplier through April 30, 2021.

Our short-term debt obligations have been recorded as liabilities on our balance sheet, and comprise $5.7comprised $16.7 million in outstanding borrowings under the tradecredit facilities of our foreign subsidiaries.subsidiaries as of June 30, 2017. The lines of credit obligation amount shown above represents scheduled principal repayments under the facilities, but not the associated interest payments which may vary based on changes in market interest rates. At SeptemberJune 30, 2016,2017, the interest rate per annum applicable to outstanding borrowings under the trade facilities of our foreign subsidiaries ranged from 1.66%2.3% to 2.38%5.9%. The amount shown above excludes $5.3 million in short-term debt obligations to related parties, which is included in the table as related-party debt (as discussed further below).

Item 3.    Quantitative and Qualitative Disclosures about Market Risk

Concentration of Credit Risk
Financial instruments which potentially subject us to concentrations of credit risk consist primarily of cash and cash equivalents, and accounts receivable. Cash and cash equivalents consist principally of financial depositsdemand deposit and money market accounts. Cash and cash equivalents are principally held with various domestic financial institutions with high credit standing. We perform ongoing credit evaluations of our customers and generally do not require collateral. Allowances are maintained for potential doubtful accounts.

We anticipate that our results of operations in any given period may depend to a large extent on sales to a small number of large accounts. As a result, our revenue for any quarter may be subject to significant volatility based upon changes in orders from one or a small number of key customers.
For the three months ended SeptemberJune 30, 20162017 and 2015, three, two customers represented 55%11% and 63%14% of net revenue, respectively. For the ninesix months ended SeptemberJune 30, 2017, one customer represented 11% ( a related-party) of net revenue. For the three months ended June 30, 2016, and 2015, three customers represented 48%34%, 21% ( a related-party) and 55%12% of net revenue, respectively. SK Broadband, LG UplusFor the six months ended June 30, 2016, three customers represented 25%, 23% (a related-party) and DASAN (a related party) each accounted for more than 10%12% of net revenue, for the three and nine months ended September 30, 2016. LG Uplus, Korea Telecom and SK Broadband each accounted for more than 10% of net revenue for the three months ended September 30, 2015. LG Uplus, Korea Telecom and Viettel Group each accounted for more than 10% of net revenue for the nine months ended September 30, 2015. Each of the foregoing customers was a customer of DNS prior to the Merger. No Legacy Zhone customers and no other DNS customers accounted for more than 10% of net revenue during the three and nine months ended September 30, 2016 and 2015.respectively.
As of SeptemberJune 30, 20162017 and December 31, 2015,, three customers accounted for 37%represented 22%, 14% and 12% of net accounts receivable.receivable, respectively. The customers who represented 22% and 12% were related parties. As of December 31, 2016, two customers represented 13% (a related-party) and 10% of net accounts receivable, respectively.
As of SeptemberJune 30, 20162017, and December 31, 2015,2016, receivables from customers in countries other than the United States represented 86%88% and 93%87%, respectively, of net accounts receivable.
Interest Rate Risk
Our exposure to market risk for changes in interest rates relates primarily to our variable rate outstanding short-term debt. As of SeptemberJune 30, 20162017, our outstanding short-term debt balance was $21.9 million.$27.0 million, which comprised $16.7 million in aggregate principal amount of borrowings under our short-term credit facilities and $10.3 million in loans from DNI and its affiliates (which bear interest at a fixed rate). Amounts borrowed under theour short-term debtcredit facilities bear interest ranging from 1.66%2.3% to 4.26%5.9% as of SeptemberJune 30, 20162017. Assuming the outstanding balance on our variable rate debt remains constant over a year, a 2% increase in the interest rate would decrease pre-tax income and cash flow by approximately $0.4$0.3 million.

Foreign Currency Risk
We transact business in various foreign countries, and a significant portion of our assets is located in Korea. We have sales operations throughout Europe, Asia, the Middle East and Latin America. We are exposed to foreign currency exchange rate risk associated with foreign currency denominated assets and liabilities, primarily intercompany receivables and payables. Accordingly, our operating results are exposed to changes in exchange rates between the U.S. dollar and those currencies. During the first ninesix months of 20162017 and during 2015,fiscal year 2016, we did not hedge any of our foreign currency exposure.
We have performed a sensitivity analysesanalysis as of SeptemberJune 30, 20162017 using a modeling technique that measures the impact on the balance sheet arising from a hypothetical 10% adverse movement in the levels of foreign currency exchange rates relative to the U.S. dollar, with all other variables held constant. The sensitivity analysesanalysis indicated that a hypothetical 10% adverse movement in foreign currency exchange rates would result in a foreign exchange loss of $0.3$2.6 million at SeptemberJune 30, 20162017. This sensitivity analysis assumes a parallel adverse shift in foreign currency exchange rates, which do not always move in the same direction. Actual results may differ materially.

Item 4.    Controls and Procedures

Disclosure Controls and Procedures
We maintain disclosure controls and procedures designed to provide reasonable assurance of achieving the objective that information required to be disclosed in our reports filed or submitted pursuant to the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and that such information is accumulated and communicated to our management, including our Co-Chief Executive Officers and Chief Financial Officer, as appropriate to allow for timely decisions regarding required disclosures. In connection withdesigning and evaluating the filingdisclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the Original Form 10-Q on November 14, 2016,desired control objectives, and management applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures.
As required by SEC Rule 13a-15(b), we conducted an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures as of June 30, 2017, the end of the period covered by this report. The controls evaluation was done under the supervision and with the participation of management, including our Co-Chief Executive Officers and our Chief Financial Officer. Based upon this evaluation, our Co-Chief Executive

Officers and Chief Financial Officer concluded that, subject to the limitations noted in Part I, Item 4 of the Original Form 10-Q, as of the end of the period covered by this report, our disclosure controls and procedures were effective, except for those pertaining to DNS, to provide reasonable assurance that information required to be disclosed in our reports under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified by the SEC, and that material information relating to DASAN Zhone and its consolidated subsidiaries is made known to management, including our Co-Chief Executive Officers and Chief Financial Officer, particularly during the period when our periodic reports are being prepared.
Subsequent to that evaluation, in connection with the restatement discussed in Note 1 of the unaudited condensed consolidated financial statements set forth in Part I, Item 1 of this report and the filing of this Form 10-Q/A, we re-evaluated the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this report. This re-evaluation was done under the supervision and with the participation of management, including our Co-Chief Executive Officers and our Chief Financial Officer. Based upon this reevaluation, our Co-Chief Executive Officers and Chief Financial Officer have concluded that, because of the material weaknesses in our internal control over financial reporting that existed as of December 31, 2016, as described below, our disclosure controls and procedures were not effective as of SeptemberJune 30, 2016.2017.
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 the registrant’s annual or interim financial statements will not be prevented or detected on a timely basis. Due to the incorrect application of generally accepted accounting principles that resulted in material misstatements and a restatement of our unaudited condensed consolidated financial statement discussed in Note 1 of the unaudited condensed consolidated financial statements set forth in Part I, Item 1 of this report, management identifiedThe material weaknesses that management previously identified in connection with its evaluation of our internal control over financial reporting. Specifically,reporting as of December 31, 2016 were as follows: we did not maintain an effective control environment as there was an insufficient complement of personnel with appropriate accounting knowledge, experience and competence, resulting in incorrect application of generally accepted accounting principles. This material weakness contributed to the following material weaknesses. We did not maintain effective controls over itsour financial close process. Also, we did not design and maintain effective controls over the review of supporting information to determine the completeness and accuracy of the accounting for complex transactions, specifically related to the business combination that occurred on September 9, 2016, which resulted in an incorrect application of generally accepted accounting principles that resulted in material misstatements and a restatement of our unaudited condensed consolidated financial statements for the three and nine months period ended September 30, 2016. Additionally, these material weaknesses could result in a misstatement in the financial statements that would result in a material misstatement in the annual or interim consolidated financial statements that would not be prevented or detected.
In light of the material weakness described above, and based on the criteria set forth in Internal Control —Integrated Framework (2013) issued by the Committee Sponsoring Organizations of the Treadway Commission (COSO), our management concluded that our internal control over financial reporting was not effective as of December 31, 2016.
As of the date of this Form 10-Q/A,report, we are re-assessing the design of our controls and modifying processes related to the accounting for significant and unusual transactions as well as enhancing monitoring and oversight controls in the application of applicable accounting guidance related to such transactions. In connection therewith, we anticipate that we will hire additional accounting personnel with relevant skills, training and experience, and conduct further training of accounting and finance personnel.


Changes in Internal Control over Financial Reporting

Except as described above, there were no changes in our internal control over financial reporting that occurred during our last fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. Merger-related integration activities may lead us to modify certain internal controls in future periods.

Inherent Limitations on Effectiveness of Controls
Our management, including our Co-Chief Executive Officers and Chief Financial Officer, does not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent or detect all error and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. The design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Further, because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, within the company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty and that breakdowns can occur because of simple error or mistake. Controls can also be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls. The design of any system of controls is based in part on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Projections of any evaluation of controls effectiveness to future periods are subject to risks. Over time, controls may become inadequate because of changes in conditions or deterioration in the degree of compliance with policies or procedures.


PART II. OTHER INFORMATION

Item 1.    Legal Proceedings

We are subject to various legal proceedings, claims and litigation arising in the ordinary course of business. While the outcome of these matters is currently not determinable, we do not expect that the ultimate costs to resolve these matters will have a material adverse effect on our consolidated financial position or results of operations. However, litigation is subject to inherent uncertainties, and unfavorable rulings could occur. If an unfavorable ruling were to occur, there exists the possibility of a material adverse impact on the results of operations of the period in which the ruling occurs, or future periods.
 
Item 1A. Risk Factors

In addition to the other information set forth in this report, you should carefully consider the factors discussed below, which we are including in this report as a result of the consummation of the Merger on September 9, 2016, and which replace and supersede the risk factors previously described in Part 1, ItemI, "Item 1A, “RiskRisk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2015.2016, which could materially affect our business, financial condition or future results. There have been no material changes to the risk factors described in the "Risk Factors" section in our Annual Report on Form 10-K for the year ended December 31, 2016. The risks described below and elsewhere in this reportour Annual Report on Form 10-K are not the only risks facing our company. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our businesses, financial condition, results of operations or prospects.

The integration of Legacy Zhone and DNS may not be completed successfully, cost-effectively or on a timely basis, and we may not realize the full benefits of the Merger.
Our ability to realize the anticipated benefits of the Merger will depend, to a large extent, on our ability to successfully integrate the Legacy Zhone and DNS businesses. Integrating and coordinating certain aspects of the operations and personnel of the two businesses and managing the expansion in the scope of our operations and financial systems involves complex operational, technological and personnel-related challenges. Our management will be required to devote a significant amount of time and attention to the process of integrating the Legacy Zhone operations with those of DNS. The potential difficulties, and resulting costs and delays, relating to the integration of the Legacy Zhone and DNS businesses include, among others:
the diversion of management’s attention from day-to-day operations;
the management of a significantly larger company than before the Merger;
the assimilation of DNS employees and the integration of the two business cultures;
challenges in attracting and retaining key personnel;
the need to integrate information, accounting, finance, sales, billing, payroll and regulatory compliance systems;
challenges in keeping existing customers and obtaining new customers; and
challenges in combining product offerings and sales and marketing activities.
There is no assurance that we will successfully or cost-effectively integrate the Legacy Zhone and DNS operations. The costs of achieving systems integration may substantially exceed our current estimates. As a non-public company prior to the Merger, DNS did not have to comply with the requirements of the Sarbanes-Oxley Act of 2002, or the Sarbanes-Oxley Act, for internal control over financial reporting and other procedures. Accordingly, neither DNS nor its independent auditors undertook a formal assessment or audit of DNS’ internal control over financial reporting prior to the Merger. However, in connection with the preparation and external audit of DNS’ consolidated financial statements as of and for the three years ended December 31, 2015 and the preparation and review of DNS’ unaudited condensed consolidated financial statements as of and for the three months ended March 31, 2016, DNS and its independent auditors noted two material weaknesses in DNS’ internal control over financial reporting. The material weaknesses that were identified were (a) lack of resources that are knowledgeable about U.S. GAAP and SEC reporting matters to allow the company to prepare the required filings on an accurate and timely basis as a U.S. domestic registrant, and (b) lack of knowledge and experience in preparing financial statements under U.S. GAAP and that comply with SEC reporting matters on a timely and accurate basis as a U.S. domestic registrant. Bringing the legacy systems for the DNS business into compliance with requirements under the Sarbanes-Oxley Act may cause us to incur substantial additional expense. In addition, the integration process may cause an interruption of, or loss of momentum in, the activities of our business. If our management is not able to effectively manage the integration process, or if any significant business activities are

interrupted as a result of the integration process, our business could suffer and its results of operations and financial condition may be harmed.
Even if the businesses of Legacy Zhone and DNS are successfully integrated, we may not realize the full benefits of the Merger, including anticipated cost synergies, growth opportunities and other financial and operating benefits, within the expected timeframe or at all. In addition, we expect to incur significant integration and restructuring expenses to realize synergies. However, many of the expenses that will be incurred are, by their nature, difficult to estimate accurately. These expenses could, particularly in the near term, exceed the savings that we expect to achieve from elimination of duplicative expenses and the realization of economies of scale and cost savings. Although we expect that the realization of efficiencies related to the integration of the businesses may offset incremental transaction, Merger-related and restructuring costs over time, we cannot give any assurance that this net benefit will be achieved in the near term, or at all. Any of these matters could adversely affect our businesses or harm our financial condition, results of operations and prospects.
Our future operating results are difficult to predict and our stock price may continue to be volatile.
As a result of a variety of factors discussed in this report, our revenues for a particular quarter are difficult to predict. Our revenue and operating results may vary significantly from quarter to quarter due to a number of factors, many of which are outside of our control. The primary factors that may affect our results of operations include the following:
commercial acceptance of our products and services;
fluctuations in demand for network access products;
the timing and size of orders from customers;
the ability of our customers to finance their purchase of our products as well as their own operations;
new product introductions, enhancements or announcements by our competitors;
our ability to develop, introduce and ship new products and product enhancements that meet customer requirements in a timely manner;
changes in our pricing policies or the pricing policies of our competitors;
the ability of our company and our contract manufacturers to attain and maintain production volumes and quality levels for our products;
our ability to obtain sufficient supplies of sole or limited source components;
increases in the prices of the components we purchase, or quality problems associated with these components;
unanticipated changes in regulatory requirements which may require us to redesign portions of our products;
changes in accounting rules, such as recording expenses for employee stock option grants;
integrating and operating any acquired businesses;
our ability to achieve targeted cost reductions;
how well we execute on our strategy and operating plans; and
general economic conditions as well as those specific to the communications, internet and related industries.
Any of the foregoing factors, or any other factors discussed elsewhere herein, could have a material adverse effect on our business, results of operations, and financial condition that could adversely affect our stock price. We anticipate that our stock price and trading volume may continue to be volatile in the future, whether due to the factors described above, volatility in public stock markets generally (particularly in the technology sector) or otherwise.
Our common stock may be delisted from The Nasdaq Capital Market, which could negatively impact the price of our common stock and our ability to access the capital markets.
On September 12, 2016, we received a staff delisting determination letter from The Nasdaq Stock Market (Nasdaq) notifying us that, because we did not satisfy Nasdaq’s initial listing standard requiring a minimum bid price of $4 per share (or a minimum closing price of $3 per share for five consecutive trading days or $2 per share for 90 consecutive trading days) at the closing of the Merger, our common stock would be subject to delisting unless we timely requested a hearing before a Nasdaq Hearings Panel (the Panel). We timely requested a hearing before the Panel with respect to the staff’s delisting determination letter, which was held on November 3, 2016. At the hearing, we presented our plan to gain

compliance with the initial listing minimum bid or closing price requirement, including via the implementation of a reverse stock split if necessary. On November 8, 2016, Nasdaq notified us that the Panel had granted our request for continued listing on Nasdaq, subject to us evidencing compliance with the initial listing minimum bid or closing price requirement by March 13, 2017. The compliance period granted by the Panel through March 13, 2017 is subject to us filing a preliminary proxy statement and a definitive proxy statement seeking stockholder approval of a reverse stock split with the SEC by January 31, 2017 and February 13, 2017, respectively. Although we intend to comply with the conditions set forth in the Panel’s determination, there can be no assurance that we will be successful in regaining compliance by the March 13, 2017 deadline, in which event the Panel will issue a final determination to delist and suspend trading of our shares on Nasdaq. Delisting from the Nasdaq Capital Market could have a material adverse effect on our business and on the trading of our common stock.
We have identified material weaknesses in our internal control over financial reporting, and we cannot provide assurances that these weaknesses will be effectively remediated or that additional material weaknesses will not occur in the future. If our internal control over financial reporting or our disclosure controls and procedures are not effective, we may not be able to accurately report our financial results, prevent fraud or file our periodic reports in a timely manner, which may cause investors to lose confidence in our reported financial information and which may lead to a decline in our stock price.
As discussed in the “Explanatory Note” and in Note 1 of our unaudited condensed consolidated financial statements for the quarterly period ended September 30, 2016, on February 20, 2017, the Audit Committee of our Board of Directors concluded, in consultation with management and after informing our independent registered public accounting firm, that, due to incorrect application of generally accepted accounting principles that resulted in material misstatements and a restatement of the Company's unaudited condensed consolidated financial statements, our previously issued interim unaudited condensed consolidated financial statements for the three and nine months ended September 30, 2016 should no longer be relied upon and required restatement. Furthermore, as discussed in “Part I, Item 4. Controls and Procedures,” our management has identified material weaknesses in our internal control over financial reporting as of September 30, 2016. 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 the registrant’s annual or interim financial statements will not be prevented or detected on a timely basis.
The Company did not maintain an effective control environment as there was an insufficient complement of personnel with appropriate accounting knowledge, experience and competence, resulting in incorrect application of generally accepted accounting principles. This material weakness contributed to the following material weaknesses. The Company did not maintain effective controls over its financial close process. Also, the Company did not design and maintain effective controls over the review of supporting information to determine the completeness and accuracy of the accounting for complex transactions, specifically related to the business combination that occurred on September 9, 2016, which resulted in an incorrect application of generally accepted accounting principles that resulted in material misstatements and a restatement of the our unaudited condensed consolidated financial statements for the three and nine months ended September 30, 2016.
As of the date of this Form 10-Q/A, we are re-assessing the design of our controls and modifying processes related to the accounting for significant and unusual transactions as well as enhancing monitoring and oversight controls in the application of applicable accounting guidance related to such transactions. In connection therewith, we anticipate that we will hire additional accounting personnel with relevant skills, training and experience, and conduct further training of accounting and finance personnel. We believe that these initiatives will remediate the material weaknesses in internal control over financial reporting described above. However, there can be no assurance that we will be able to fully remediate our existing material weaknesses or that our internal control over financial reporting will not suffer in the future from other material weaknesses, thus making us unable to prevent or detect on a timely basis material misstatements in our periodic reports with the SEC. If we fail to remediate these material weaknesses or otherwise maintain effective internal control over financial reporting in the future, the existence of one or more internal control deficiencies could result in errors in our financial statements, and substantial costs and resources may be required to rectify internal control deficiencies. If we cannot produce reliable financial reports, we may have difficulty in filing timely periodic reports with the SEC, investors could lose confidence in our reported financial information, the market price of our stock could decline significantly, we may be unable to obtain additional financing to operate and expand our business, and our business and financial condition could be materially harmed. In addition, any failure to remediate the existing material weaknesses or a failure to maintain effective internal control over financial reporting could negatively impact our results of operations, cash flows and financial condition, subject us to potential litigation and regulatory inquiry and cause us to incur additional costs in future periods relating to the implementation of remedial measures.

We have experienced significant losses and we may incur losses in the future. If we fail to generate sufficient revenue to sustain our profitability, our stock price could decline.
We have incurred significant losses to date and expect that our operating losses and negative cash flows from operations may continue. Our net loss was $8.6 million and$3.0 million for the nine months ended September 30, 2016 and year ended December 31, 2015, respectively, and we had an accumulated deficit of $12.8 millionat September 30, 2016. We have significant fixed expenses and expect that we will continue to incur substantial manufacturing, research and product development, sales and marketing, customer support, administrative and other expenses in connection with the ongoing development of our business. In addition, we may be required to spend more on research and product development than originally budgeted to respond to industry trends. We may also incur significant new costs related to acquisitions and the integration of new technologies and other acquisitions that may occur in the future. We may not be able to adequately control costs and expenses or achieve or maintain adequate operating margins. As a result, our ability to sustain profitability in future periods will depend on our ability to generate and sustain higher revenue while maintaining reasonable cost and expense levels. If we fail to generate sufficient revenue to sustain profitability in future periods, we may continue to incur operating losses, which could be substantial, and our stock price could decline.
Our level of indebtedness could adversely affect our business, operating results and financial condition.
We have a significant amount of indebtedness. As of September 30, 2016, the aggregate principal amount of our total outstanding indebtedness was $26.9 million, which comprised $20.1 million in short-term borrowings under various financing arrangements of our foreign subsidiaries and $6.8 million in related party borrowings. We may incur additional indebtedness in the future, including additional borrowings under the WFB Facility. The level of indebtedness could have important consequences and could materially and adversely affect us in a number of ways, including:
limiting our ability to obtain additional financing in the future for working capital, capital expenditures, acquisitions or general corporate purposes;
limiting our flexibility to plan for, or react to, changes in our business or market conditions;
requiring us to use a significant portion of any future cash flow from operations to repay or service the debt, thereby reducing the amount of cash available for other purposes;
making us more highly leveraged than some of our competitors, which may place us at a competitive disadvantage; and
making us more vulnerable to the impact of adverse economic and industry conditions and increases in interest rates.
The WFB Facility and the instruments governing our other indebtedness include covenants (including, in the case of the WFB Facility, financial ratios) that may restrict our ability to operate our business. These covenants restrict, among other matters, our ability to incur additional indebtedness, grant liens, sell or dispose of assets, make loans and investments, pay dividends, redeem or repurchase capital stock, enter into affiliate transactions and consolidate or merger with, or sell substantially all of our assets to, another person. If we default under the WFB Facility or other instrument governing our other indebtedness because of a covenant breach or otherwise, all amounts outstanding thereunder could become immediately due and payable. In addition, WFB may be entitled to, among other things, sell our assets to satisfy the obligations under the WFB Facility. In the past we have violated the covenants in our former revolving line of credit and letter of credit facility and received waivers for these violations. We were in compliance with our covenants under our WFB Facility as of September 30, 2016. We cannot assure you that we will be able to comply with our financial or other covenants in the future or that any covenant violations will be waived in the future. Any acceleration of amounts due could have a material adverse effect on our liquidity and financial condition.
We cannot assure you that we will be able to generate cash flow in amounts sufficient to enable us to service our debt or to meet our working capital and capital expenditure requirements. If we are unable to generate sufficient cash flow from operations or to borrow sufficient funds to service our debt, due to borrowing base restrictions or otherwise, we may be required to sell assets, reduce capital expenditures, purchase credit insurance or obtain additional financing. We cannot assure you that we will be able to engage in any of these actions on reasonable terms, if at all.
If we are unable to obtain additional capital to fund our existing and future operations, we may be required to reduce the scope of our planned product development, and marketing and sales efforts, which would harm our business, financial condition and results of operations.

The development and marketing of new products, and the expansion of our direct sales operations and associated support personnel requires a significant commitment of resources. We may incur significant losses or expend significant amounts of capital if:
the market for our products develops more slowly than anticipated;
we fail to establish market share or generate revenue at anticipated levels;
our capital expenditure forecasts change or prove inaccurate; or
we fail to respond to unforeseen challenges or take advantage of unanticipated opportunities.
As a result, we may need to raise substantial additional capital. Additional capital, if required, may not be available on acceptable terms, or at all. If additional capital is raised through the issuance of debt securities or other debt financing, the terms of such debt may include covenants, restrictions and financial ratios that may restrict our ability to operate our business. In addition, volatility in our stock price may make it more difficult or costly for us to raise capital through the issuance of common stock, preferred stock or other equity securities. If we elect to raise equity capital, this may be dilutive to existing stockholders and could reduce the trading price of our common stock. If we are unable to obtain additional capital or are required to obtain additional capital on terms that are not favorable to us, we may be required to reduce the scope of our planned product development and sales and marketing efforts beyond the reductions that we have previously taken, which could have a material adverse effect on our business, financial condition and results of operations.
Our lack of liquid funds and other sources of financing may limit our ability to maintain our existing operations, grow our business and compete effectively.
As of September 30, 2016, we had approximately $33.6 million in cash and cash equivalents and $26.9 million in aggregate principal amount outstanding under our debt facilities and other financing arrangements. Our current lack of liquidity could harm us by:
increasing our vulnerability to adverse economic conditions in our industry or the economy in general;
requiring substantial amounts of cash to be used for debt servicing, rather than other purposes, including operations;
limiting our ability to plan for, or react to, changes in our business and industry; and
influencing investor and customer perceptions about our financial stability and limiting our ability to obtain financing or acquire customers.
In order to meet our liquidity needs and finance our capital expenditures and working capital needs for our business, we may be required to sell assets, issue debt or equity securities, purchase credit insurance, or borrow on potentially unfavorable terms. In addition, we may be required to reduce our operations in low margin regions, including reductions in headcount. We may be unable to sell assets, access additional indebtedness or undertake other actions to meet these needs. As a result, we may become unable to pay our ordinary expenses, including our debt service, on a timely basis. If additional capital is raised through the issuance of debt securities or other debt financing, the terms of such debt may include covenants, restrictions and financial ratios that may restrict our ability to operate our business. Likewise, any equity financing could result in additional dilution of our stockholders. If we are unable to sell assets, issue securities or access additional indebtedness to meet these needs on favorable terms, or at all, we may become unable to pay our ordinary expenses, including our debt service, on a timely basis and may be required to reduce the scope of our planned product development and sales and marketing efforts beyond the reductions we have previously taken. In addition, we may not be able to fund our business expansion, take advantage of future opportunities, or respond to competitive pressures or unanticipated capital requirements, any of which could have a material adverse effect on our business, financial condition and results of operations.
Our business and future operating results are subject to global economic and market conditions.
Market turbulence and weak economic conditions, as well as concerns about energy costs, geopolitical issues, the availability and cost of credit, business and consumer confidence, and unemployment could impact our business in a number of ways, including:

Potential deferment of purchases and orders by customers: Uncertainty about global economic conditions may cause consumers, businesses and governments to defer purchases in response to flat revenue budgets, tighter credit, decreased

cash availability and weak consumer confidence. Accordingly, future demand for our products could differ materially from our current expectations.

Customers’ inability to obtain financing to make purchases from us and/or maintain their business: Some of our customers require substantial financing in order to finance their business operations, including capital expenditures on new equipment and equipment upgrades, and make purchases from us. The potential inability of these customers to access the capital needed to finance purchases of our products and meet their payment obligations to us could adversely impact our financial condition and results of operations. To sell to some of these customers, we may be required to assume incremental risks of uncollectible accounts or to extend credit or credit support. While we monitor these situations carefully and attempt to take appropriate measures to protect ourselves, including factoring credit arrangements to financial institutions, it is possible that we may have to defer revenue until cash is collected or write-down or write-off uncollectible accounts. Such write-downs or write-offs, if large, could have a material adverse effect on our results of operations and financial condition. If our customers become insolvent due to market and economic conditions or otherwise, it could have a material adverse impact on our business, financial condition and results of operations.

Negative impact from increased financial pressures on third-party dealers, distributors and retailers: We make sales in certain regions through third-party dealers, distributors and retailers. These third parties may be impacted, among other things, by a significant decrease in available credit. If credit pressures or other financial difficulties result in insolvency for these third parties and we are unable to successfully transition end customers to purchase our products from other third parties, or from us directly, it could adversely impact our financial condition and results of operations.

Negative impact from increased financial pressures on key suppliers: Our ability to meet customers’ demands depends, in part, on our ability to obtain timely and adequate delivery of quality materials, parts and components from our suppliers. Certain of our components are available only from a single source or limited sources. If certain key suppliers were to become capacity constrained or insolvent, it could result in a reduction or interruption in supplies or a significant increase in the price of supplies and adversely impact our financial condition and results of operations. In addition, credit constraints of key suppliers could result in accelerated payment of accounts payable by Zhone, impacting our cash flow.
We may experience material adverse impacts on our business, operating results and financial condition as a result of weak or recessionary economic or market conditions in the United States, Korea or the rest of the world.
If demand for our products and solutions does not develop as we anticipate, then our results of operations and financial condition will be adversely affected.
Our future revenue depends significantly on our ability to successfully develop, enhance and market our products and solutions to our target markets. Most network service providers have made substantial investments in their current infrastructure, and they may elect to remain with their current architectures or to adopt new architectures in limited stages or over extended periods of time. A decision by a customer to purchase our products will involve a significant capital investment. We must convince our service provider customers that they will achieve substantial benefits by deploying our products for future upgrades or expansions. We may experience difficulties with product reliability, partnering, and sales and marketing efforts that could adversely affect our business and divert management attention and resources from our core business. We do not know whether a viable market for our products and solutions will develop or be sustainable in our businesses. If these markets do not develop or develop more slowly than we expect, our business, financial condition and results of operations will be seriously harmed.
We depend upon the development of new products and enhancements to existing products, and if we fail to predict and respond to emerging technological trends and customers’ changing needs, our operating results and market share may suffer.
The markets for our products are characterized by rapidly changing technology, evolving industry standards, changes in end-user requirements, frequent new product introductions and changes in communications offerings from network service provider customers. Our future success depends on our ability to anticipate or adapt to such changes and to offer, on a timely and cost-effective basis, products that meet changing customer demands and industry standards. We may not have sufficient resources to successfully and accurately anticipate customers’ changing needs and technological trends, manage long development cycles or develop, introduce and market new products and enhancements. The process of developing new technology is complex and uncertain, and if we fail to develop new products or enhancements to existing products on a timely and cost-effective basis, or if our new products or enhancements fail to achieve market acceptance, our business, financial condition and results of operations would be materially adversely affected.

Because our products are complex and are deployed in complex environments, our products may have defects that we discover only after full deployment by our customers, which could seriously harm our business.
We produce highly complex products that incorporate leading-edge technology, including both hardware and software. Software typically contains defects or programming flaws that can unexpectedly interfere with expected operations. In addition, our products are complex and are designed to be deployed in large quantities across complex networks. Because of the nature of these products, they can only be fully tested when completely deployed in large networks with high amounts of traffic, and there is no assurance that our pre-shipment testing programs will be adequate to detect all defects. As a result, our customers may discover errors or defects in our hardware or software, or our products may not operate as expected, after they have been fully deployed by our customers. If we are unable to cure a product defect, we could experience damage to our reputation, reduced customer satisfaction, loss of existing customers and failure to attract new customers, failure to achieve market acceptance, reduced sales opportunities, loss of revenue and market share, increased service and warranty costs, diversion of development resources, legal actions by our customers, and increased insurance costs. Defects, integration issues or other performance problems in our products could also result in financial or other damages to our customers. Our customers could seek damages for related losses from us, which could seriously harm our business, financial condition and results of operations. A product liability claim brought against us, even if unsuccessful, would likely be time consuming and costly. The occurrence of any of these problems would seriously harm our business, financial condition and results of operations.

Due to the international nature of our business, political or economic changes or other factors in a specific country or region could harm our future revenue, costs and expenses and financial condition.
We currently have significant operations in Korea, as well sales and technical support teams in various locations around the world. Many of our international sales may be denominated in foreign currencies. Because we do not currently engage in material foreign currency hedging transactions related to international sales, a decrease in the value of foreign currencies relative to the U.S. dollar could result in losses from transactions denominated in foreign currencies. We expect to continue expanding our international operations in the future. The successful management and expansion of our international operations requires significant human effort and the commitment of substantial financial resources. Further, our international operations may be subject to certain risks and challenges that could harm our operating results, including:
unexpected changes in laws, policies and regulatory requirements, including but not limited to regulations related to import-export control;
trade protection measures, tariffs, embargoes and other regulatory requirements which may affect our ability to import or export our products into or from various countries;
political considerations that affect service provider and government spending patterns;
differing technology standards or customer requirements;
developing and customizing our products for foreign countries;
fluctuations in currency exchange rates, foreign exchange controls and restrictions on cash repatriation;
longer accounts receivable collection cycles and financial instability of customers;
requirements for additional liquidity to fund our international operations;
difficulties and excessive costs for staffing and managing foreign operations;
ineffective legal protection of our intellectual property rights in certain countries;
potentially adverse tax consequences; and
changes in a country’s or region’s political and economic conditions.
In addition, some of our customer purchase agreements are governed by foreign laws, which may differ significantly from U.S. laws. We may be limited in our ability to enforce our rights under these agreements and to collect damages, if awarded. Any of these factors could harm our existing international operations and business or impair our ability to continue expanding into international markets.
We are subject to Korean foreign currency exchange rate risk.
We conduct significant business in Korea, which subjects us to foreign currency exchange rate risk. Currently, we do not hold or issue foreign currency forward contracts, option contracts or other derivative financial instruments to mitigate the currency exchange rate risk. Our results of operations and our cash flows could be impacted by changes in foreign currency exchange rates.

A shortage of adequate component supply or manufacturing capacity could increase our costs or cause a delay in our ability to fulfill orders, and our failure to estimate customer demand properly may result in excess or obsolete component inventories that could adversely affect our gross margins.
Occasionally, we may experience a supply shortage, or a delay in receiving, certain component parts as a result of strong demand for the component parts and/or capacity constraints or other problems experienced by suppliers. If shortages or delays persist, the price of these components may increase, or the components may not be available at all, and we may also encounter shortages if we do not accurately anticipate our needs. Conversely, we may not be able to secure enough components at reasonable prices or of acceptable quality to build new products in a timely manner in the quantities or configurations needed. Accordingly, our revenue and gross margins could suffer until other sources can be developed. Our operating results would also be adversely affected if, anticipating greater demand than actually develops, we commit to the purchase of more components than we need. Furthermore, as a result of binding price or purchase commitments with suppliers, we may be obligated to purchase components at prices that are higher than those available in the current market. In the event that we become committed to purchase components at prices in excess of the current market price when the components are actually used, our gross margins could decrease. In the past we experienced component shortages that adversely affected our financial results and in the future may continue to experience component shortages.
We rely on contract manufacturers for a portion of our manufacturing requirements.
We rely on contract manufacturers to perform a portion of the manufacturing operations for our products. These contract manufacturers build product for other companies, including our competitors. In addition, we do not have contracts in place with some of these providers and may not be able to effectively manage those relationships. We cannot be certain that our contract manufacturers will be able to fill our orders in a timely manner. We face a number of risks associated with this dependence on contract manufacturers including reduced control over delivery schedules, the potential lack of adequate capacity during periods of excess demand, poor manufacturing yields and high costs, quality assurance, increases in prices, and the potential misappropriation of our intellectual property. We have experienced in the past, and may experience in the future, problems with our contract manufacturers, such as inferior quality, insufficient quantities and late delivery of products.
We depend on a limited source of suppliers for several key components. If we are unable to obtain these components on a timely basis, we will be unable to meet our customers’ product delivery requirements, which would harm our business.
We currently purchase several key components from a limited number of suppliers. If any of our limited source of suppliers become insolvent, cease business or experience capacity constraints, work stoppages or any other reduction or disruption in output, they may be unable to meet our delivery schedules. Our suppliers may enter into exclusive arrangements with our competitors, be acquired by our competitors, stop selling their products or components to us at commercially reasonable prices, refuse to sell their products or components to us at any price or be unable to obtain or have difficulty obtaining components for their products from their suppliers. If we do not receive critical components from our limited source of suppliers in a timely manner, we will be unable to meet our customers’ product delivery requirements. Any failure to meet a customer’s delivery requirements could materially adversely affect our business, operating results and financial condition and could materially damage customer relationships.
Our target customer base is concentrated, and the loss of one or more of our customers could harm our business.
The target customers for our products are network service providers that operate voice, data and video communications networks. There are a limited number of potential customers in our target market. For the nine months ended September 30, 2016 and year ended December 31, 2015, three customers represented 55% and 63% of net revenue, respectively. SK Broadband, LG Uplus and DASAN (a related party) each accounted for more than 10% of net revenue for the three months ended September 30, 2016. SK Broadband, LG Uplus,Viettel and DASAN (a related party) each accounted for more than 10% of net revenue for the nine months ended September 30, 2016. LG Uplus, Korea Telecom and SK Broadband each accounted for more than 10% of net revenue for the three months ended September 30, 2015. LG Uplus, Korea Telecom and Viettel Group each accounted for more than 10% of net revenue for the nine months ended September 30, 2015. Each of the foregoing customers was a customer of DNS prior to the Merger. No Legacy Zhone customers and no other DNS customers accounted for more than 10% of net revenue during the three and nine months ended September 30, 2016 and 2015. We expect that a significant portion of our future revenue will depend on sales of our products to a limited number of customers. As a result, our revenue for any quarter may be subject to significant volatility based on changes in orders from one or a small number of key customers. Any failure of one or more customers to purchase products from us for any reason, including any downturn in their businesses, would seriously harm our business, financial condition and results of operations.

Industry consolidation may lead to increased competition and may harm our operating results.
There has been a trend toward industry consolidation in the communications equipment market for several years. We expect this trend to continue as companies attempt to strengthen or hold their market positions in an evolving industry and as companies are acquired or are unable to continue operations. We believe that industry consolidation may result in stronger competitors that are better able to compete as sole-source vendors for customers. This could have a material adverse effect on our business, financial condition and results of operations. Furthermore, rapid consolidation could result in a decrease in the number of customers we serve. Loss of a major customer could have a material adverse effect on our business, financial condition and results of operations.
The market we serve is highly competitive and we may not be able to compete successfully.
Competition in the communications equipment market is intense. This market is characterized by rapid change, converging technologies and a migration to networking solutions that offer superior advantages. We are aware of many companies in related markets that address particular aspects of the features and functions that our products provide. Currently, our primary competitors in our core business include Alcatel-Lucent, Calix, Adtran, Huawei, and ZTE, among others. In our FiberLAN business, our competitors include Tellabs and Cisco. We also may face competition from other large communications equipment companies or other companies that may enter our market in the future. In addition, a number of companies have introduced products that address the same network needs that our products address, both domestically and abroad. Many of our competitors have longer operating histories, greater name recognition, larger customer bases and greater financial, technical, sales and marketing resources than we do and may be able to undertake more extensive marketing efforts, adopt more aggressive pricing policies and provide more customer financing than we can. In particular, we are encountering price-focused competitors from Asia, especially China, which places pressure on us to reduce our prices. If we are forced to reduce prices in order to secure customers, we may be unable to sustain gross margins at desired levels or achieve profitability. Competitive pressures could result in increased pricing pressure, reduced profit margins, increased sales and marketing expenses and failure to increase, or the loss of, market share, any of which could reduce our revenue and adversely affect our financial results. Moreover, our competitors may foresee the course of market developments more accurately than we do and could develop new technologies that render our products less valuable or obsolete.
In our markets, principal competitive factors include:
product performance;
interoperability with existing products;
scalability and upgradeability;
conformance to standards;
breadth of services;
reliability;
ease of installation and use;
geographic footprints for products;
ability to provide customer financing;
price;
technical support and customer service; and
brand recognition.
If we are unable to compete successfully against our current and future competitors, we may have difficulty obtaining or retaining customers, and we could experience price reductions, order cancellations, increased expenses and reduced gross margins, any of which could have a material adverse effect on our business, financial condition and results of operations.
Our success largely depends on our ability to retain and recruit key personnel, and any failure to do so would harm our ability to meet key objectives.
Our future success depends upon the continued services of our Co-Chief Executive Officers and our other executive officers, our ability to identify, attract and retain highly skilled technical, managerial, sales and marketing personnel who have critical industry experience and relationships that we rely on to build our business. The loss of the services of any of our key employees, including our Co-Chief Executive Officers and our Chief Financial Officer, could delay the

development and production of our products and negatively impact our ability to maintain customer relationships, which would harm our business, financial condition and results of operations. Moreover, our inability to attract and retain sufficient qualified accounting personnel with expertise in GAAP following the Merger may adversely affect our ability to maintain an effective system of internal controls or our ability to produce reliable financial reports, which may materially and adversely affect our business.

Any strategic acquisitions or investments we make could disrupt our operations and harm our operating results.
On an ongoing basis, we may evaluate acquisitions of, or investments in, complementary companies, products or technologies to supplement our internal growth, may acquire additional businesses, products or technologies in the future. If we do complete future acquisitions, we could:
issue stock that would dilute our current stockholders’ percentage ownership;
consume a substantial portion of our cash resources;
incur substantial debt;
assume liabilities;
increase our ongoing operating expenses and level of fixed costs;
record goodwill and non-amortizable intangible assets that will be subject to impairment testing and potential periodic impairment charges;
incur amortization expenses related to certain intangible assets;
incur large and immediate write-offs; and
become subject to litigation.
Any acquisitions or investments that we make in the future will involve numerous risks, including:
difficulties in integrating the operations, technologies, products and personnel of the acquired companies;
unanticipated costs;
diversion of management’s time and attention away from normal daily operations of the business and the challenges of managing larger and more widespread operations resulting from acquisitions;
difficulties in entering markets in which we have no or limited prior experience;
insufficient revenues to offset increased expenses associated with acquisitions and where competitors in such markets have stronger market positions; and
potential loss of key employees, customers, distributors, vendors and other business partners of the companies we acquire following and continuing after announcement of acquisition plans.
Mergers and acquisitions of high-technology companies are inherently risky and subject to many factors outside of our control, and we cannot be certain that our previous or future acquisitions will be successful and will not materially adversely affect our business, operating results or financial condition. We do not know whether we will be able to successfully integrate the businesses, products, technologies or personnel that we might acquire in the future or that any strategic investments we make will meet our financial or other investment objectives. Any failure to do so could seriously harm our business, financial condition and results of operations.
Sales to communications service providers are especially volatile, and weakness in sales orders from this industry may harm our operating results and financial condition.
Sales activity in the service provider industry depends upon the stage of completion of expanding network infrastructures, the availability of funding, and the extent to which service providers are affected by regulatory, economic and business conditions in the country of operations. Although some service providers may be increasing capital expenditures over the depressed levels that have prevailed over the last few years, weakness in orders from this industry could have a material adverse effect on our business, operating results and financial condition. Slowdowns in the general economy, overcapacity, changes in the service provider market, regulatory developments and constraints on capital availability have had a material adverse effect on many of our service provider customers, with many of these customers going out of business or substantially reducing their expansion plans. These conditions have materially harmed our business and operating results, and we expect that some or all of these conditions may continue for the foreseeable future. Finally, service provider customers typically have longer implementation cycles; require a broader range of service including design services;

demand that vendors take on a larger share of risks; often require acceptance provisions, which can lead to a delay in revenue recognition; and expect financing from vendors. All these factors can add further risk to business conducted with service providers.
Compliance or the failure to comply with current and future environmental regulations could cause us significant expense.
We are subject to a variety of federal, state, local and foreign environmental regulations. If we fail to comply with any present and future regulations, we could be subject to future liabilities, the suspension of production or a prohibition on the sale of our products. In addition, such regulations could require us to incur other significant expenses to comply with environmental regulations, including expenses associated with the redesign of any non-compliant product. From time to time new regulations are enacted, and it is difficult to anticipate how such regulations will be implemented and enforced. For example, in 2003 the European Union enacted the Restriction on the Use of Certain Hazardous Substances in Electrical and Electronic Equipment Directive (RoHS) and the Waste Electrical and Electronic Equipment Directive (WEEE), for implementation in European Union member states. We are aware of similar legislation that is currently in force or is being considered in the United States, as well as other countries, such as Japan and China. Our failure to comply with any of such regulatory requirements or contractual obligations could result in our being liable for costs, fines, penalties and third-party claims, and could jeopardize our ability to conduct business in countries in the jurisdictions where these regulations apply.
Adverse resolution of litigation may harm our operating results or financial condition.
We are a party to various lawsuits and claims in the normal course of our business. Litigation can be expensive, lengthy, and disruptive to normal business operations. Moreover, the results of complex legal proceedings are difficult to predict. An unfavorable resolution of a particular lawsuit could have a material adverse effect on our business, operating results and financial condition.
Our intellectual property rights may prove difficult to protect and enforce.
We generally rely on a combination of copyrights, patents, trademarks and trade secret laws and restrictions on disclosure to protect our intellectual property rights. We also enter into confidentiality or license agreements with our employees, consultants and corporate partners, and control access to and distribution of our proprietary information. Despite our efforts to protect our proprietary rights, unauthorized parties may attempt to copy or otherwise obtain and use our products or technology. Monitoring unauthorized use of our technology is difficult, and we do not know whether the steps we have taken will prevent unauthorized use of our technology, particularly in foreign countries where the laws may not protect our proprietary rights as extensively as in the United States. We cannot assure you that our pending, or any future, patent applications will be granted, that any existing or future patents will not be challenged, invalidated, or circumvented, or that any existing or future patents will be enforceable. While we are not dependent on any individual patents, if we are unable to protect our proprietary rights, we may find ourselves at a competitive disadvantage to others who need not incur the substantial expense, time and effort required to create the innovative products.
We may be subject to intellectual property infringement claims that are costly and time consuming to defend and could limit our ability to use some technologies in the future.
Third parties have in the past and may in the future assert claims or initiate litigation related to patent, copyright, trademark and other intellectual property rights to technologies and related standards that are relevant to us. The asserted claims or initiated litigation can include claims against us or our manufacturers, suppliers or customers alleging infringement of their proprietary rights with respect to our existing or future products, or components of those products. We have received correspondence from companies claiming that many of our products are using technology covered by or related to the intellectual property rights of these companies and inviting us to discuss licensing arrangements for the use of the technology. Regardless of the merit of these claims, intellectual property litigation can be time consuming and costly, and result in the diversion of technical and management personnel. Any such litigation could force us to stop selling, incorporating or using our products that include the challenged intellectual property, or redesign those products that use the technology. In addition, if a party accuses us of infringing upon its proprietary rights, we may have to enter into royalty or licensing agreements, which may not be available on terms acceptable to us, if at all. If we are unsuccessful in any such litigation, we could be subject to significant liability for damages and loss of our proprietary rights. Any of these results could have a material adverse effect on our business, financial condition and results of operations.
We rely on the availability of third party licenses.

Many of our products are designed to include software or other intellectual property licensed from third parties. It may be necessary in the future to seek or renew licenses relating to various elements of the technology used to develop these products. We cannot assure you that our existing and future third-party licenses will be available to us on commercially reasonable terms, if at all. Our inability to maintain or obtain any third-party license required to sell or develop our products and product enhancements could require us to obtain substitute technology of lower quality or performance standards, or at greater cost.
The long and variable sales cycles for our products may cause revenue and operating results to vary significantly from quarter to quarter.
The target customers for our products have substantial and complex networks that they traditionally expand in large increments on a periodic basis. Accordingly, our marketing efforts are focused primarily on prospective customers that may purchase our products as part of a large-scale network deployment. Our target customers typically require a lengthy evaluation, testing and product qualification process. Throughout this process, we are often required to spend considerable time and incur significant expense educating and providing information to prospective customers about the uses and features of our products. Even after a company makes the final decision to purchase our products, it may deploy our products over extended periods of time. The timing of deployment of our products varies widely, and depends on a number of factors, including our customers’ skill sets, geographic density of potential subscribers, the degree of configuration and integration required to deploy our products, and our customers’ ability to finance their purchase of our products as well as their operations. As a result of any of these factors, our revenue and operating results may vary significantly from quarter to quarter.
Decreased effectiveness of share-based compensation could adversely affect our ability to attract and retain employees.
We have historically used stock options as a key component of our employee compensation program in order to align the interests of our employees with the interests of our stockholders, encourage employee retention and provide competitive compensation and benefit packages. If the trading price of our common stock declines, this would reduce the value of our share-based compensation to our present employees and could affect our ability to retain existing or attract prospective employees. Difficulties relating to obtaining stockholder approval of equity compensation plans could also make it harder or more expensive for us to grant share-based payments to employees in the future.
Our industry is subject to government regulations, which could harm our business.
Our operations are subject to various laws and regulations, including those regulations promulgated by the FCC. The FCC has jurisdiction over the entire communications industry in the United States and, as a result, our existing and future products and our customers’ products are subject to FCC rules and regulations. Changes to current FCC rules and regulations and future FCC rules and regulations could negatively affect our business. The uncertainty associated with future FCC decisions may cause network service providers to delay decisions regarding their capital expenditures for equipment for broadband services. In addition, international regulatory bodies establish standards that may govern our products in foreign markets. The SEC has adopted disclosure rules regarding the use of “conflict minerals” mined from the Democratic Republic of Congo and adjoining countries (DRC) and procedures regarding a manufacturer’s efforts to prevent the sourcing of such conflict minerals. These rules may have the effect of reducing the pool of suppliers who can supply DRC “conflict free” components and parts, and we may not be able to obtain DRC conflict free products or supplies in sufficient quantities for our operations. Also, we may face reputational challenges with our customers, stockholders and other stakeholders if we are unable to sufficiently verify the origins for the conflict minerals used in our products. We are unable to predict the scope, pace or financial impact of government regulations and other policy changes that could be adopted in the future, any of which could negatively impact our operations and costs of doing business. Because of our smaller size, legislation or governmental regulations can significantly increase our costs and affect our competitive position. Changes to or future domestic and international regulatory requirements could result in postponements or cancellations of customer orders for our products and services, which would harm our business, financial condition and results of operations. Further, we cannot be certain that we will be successful in obtaining or maintaining regulatory approvals that may, in the future, be required to operate our business.
Our business and operations are especially subject to the risks of earthquakes and other natural catastrophic events.
Our corporate headquarters, including a significant portion of our research and development operations, are located in Northern California, a region known for seismic activity. Additionally, some of our facilities, including our manufacturing facilities, are located near geographic areas that have experienced hurricanes in the past. A significant natural disaster, such

as an earthquake, hurricane, fire, flood or other catastrophic event, could severely affect our ability to conduct normal business operations, and as a result, our future operating results could be materially and adversely affected.
Our executive officers and directors and entities affiliated with them own or control a large percentage of our common stock, which permits them to exercise significant control over us.
As of September 30, 2016, our executive officers and directors and entities affiliated with them owned, in the aggregate, approximately 64% of the outstanding shares of our common stock. Accordingly, these stockholders will be able to substantially influence all matters requiring approval by our shareholders, including the approval of mergers or other business combination transactions and the composition of our Board of Directors. This concentration of ownership may also delay, defer or even prevent a change in control of our company and would make some transactions more difficult or impossible without their support, even if such a transaction would be beneficial to our other stockholders. Circumstances may arise in which the interests of these stockholders could conflict with the interests of our other stockholders. In addition, provisions of our certificate of incorporation, bylaws and Delaware law could make it more difficult for a third party to acquire us, even if doing so would be beneficial to certain stockholders.
Future sales of our common stock could lower our stock price and dilute existing shareholders.
We issued a total of approximately 9.5 million shares (post reverse split) of our common stock to DASAN in connection with the Merger, and may issue additional shares of common stock to finance future acquisitions through the use of equity. DASAN has the right to require us to register with the SEC resales of the shares issued in connection with the Merger from time to time. In the event that DASAN exercises its registration rights with respect to such shares, such shares would become eligible for resale upon registration. Additionally, shares of our common stock are available for future sale pursuant to awards granted under our equity incentive plans. Our stock price may suffer a significant decline as a result of any sudden increase in the number of shares sold in the public market or market perception that the increased number of shares available for sale will exceed the demand for our common stock.
There is a limited public market of our common stock.
There is a limited public market for our common stock. The average daily trading volume in our common stock during the nine months ended September 30, 2016 was approximately 16,600 shares (post reverse split) per day. We cannot provide assurances that a more active trading market will develop or be sustained. As a result of low trading volume in our common stock, the purchase or sale of a relatively small number of shares of our common stock could result in significant price fluctuations and it may be difficult for holders to sell their shares without depressing the market price for our common stock.
