FINANCIAL STATEMENTS

8x8, Inc. (8x8 or the Company) is a leading provider of global cloud communications and customer engagement solutions to over a million business users worldwide. The Company's suite of products weaves together cloud communications, conferencing, collaboration and contact center solutions so today's organization can deliver exceptional employee and customer experiences. 8x8 technology provides one integrated platform for employees and customers engagement solutions, as well as a real-time data analytics platform for constant learning and improvement.

The Company's fiscal year ends on March 31 of each calendar year. Each reference to a fiscal year in these notes to the consolidated financial statements refers to the fiscal year ended March 31 of the calendar year indicated (for example, fiscal 2018 refers to the fiscal year ending March 31, 2018).

The accompanying interim condensed consolidated financial statements are unaudited and have been prepared on substantially the same basis as our annual consolidated financial statements for the fiscal year ended March 31, 2017. In the opinion of the Company's management, these interim condensed consolidated financial statements reflect all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair statement of our financial position, results of operations, and cash flows for the periods presented. The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, 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 periods. Actual results could differ from these estimates.

The March 31, 2017 year-end condensed consolidated balance sheet data in this document were derived from audited consolidated financial statements and does not include all of the disclosures required by U.S. generally accepted accounting principles. These condensed consolidated financial statements should be read in conjunction with the Company's audited consolidated financial statements as of and for the fiscal year ended March 31, 2017 and notes thereto included in the Company's fiscal 2017 Annual Report on Form 10-K.

The results of operations and cash flows for the interim periods included in these condensed consolidated financial statements are not necessarily indicative of the results to be expected for any future period or the entire fiscal year.

Certain software development costs capitalized in accordance with ASC 350-40, Internal Use Software (ASC 350-40), that were presented in other long-term assets in the Company's consolidated balance sheets as of March 31, 2017 are presented as property and equipment for the condensed consolidated balance sheet as of December 31, 2017. Assets in the amount of $7.7 million, net of accumulated amortization, have been reclassified in the balance sheet as of March 31, 2017 to conform to the current period presentation. The reclassification had no impact on the Company's previously reported consolidated net income (loss), cash flows, or basic or diluted net income per share amounts.

Certain amounts previously reported within the Company's condensed consolidated balance sheets and condensed consolidated statements of cash flows have been reclassified within each financial statement section to conform to the current period presentation. The reclassification had no impact on the Company's previously reported net loss, cash flows, or basic or diluted net loss per share amounts.

DXI

In May 2015, the Company entered into a share purchase agreement with the shareholders of DXI Limited for a purchase price of $22.5 million, consisting of $18.7 million in cash paid to the DXI shareholders at closing and $3.8 million in cash deposited into escrow to be held for two years as security against indemnity claims made by the Company after the closing date. During the fiscal quarter ended June 30, 2017, $1.4 million of the cash held in escrow was returned to the Company and the escrow fund was closed. Since the purchase accounting for the acquisition was finalized by March 31, 2016, the proceeds are realized as a gain and reported as other income in the consolidated statements of operations.

The Company performs its annual goodwill impairment test on January 1 of each year and during the year, whenever a triggering event for such an assessment is identified. During the third quarter of fiscal year 2018, the Company changed its product and marketing strategy for the use of DXI's technology and re-assessed the profitability outlook which triggered the requirement that the Company test the recorded goodwill for impairment in accordance with ASC 350-20-35, as amended by ASU 2017-04 (see Footnote 1, Recently Adopted Accounting Pronouncements). First, the Company estimated the fair value of its three reporting units using the market approach. Under the market approach, the Company utilized the market capitalization of its publicly-traded shares and comparable company information to determine revenue multiples which were used to determine the fair value of the reporting unit. Based on this approach, the Company determined that there was an indication of impairment for its DXI reporting unit in the UK as the carrying value including goodwill exceeded the estimated fair value. As largely independent cash flows could not be attributed to any assets individually the Company evaluated DXI's assets and liabilities as one asset group. Then the Company estimated the fair value of DXI's assets and liabilities as one asset group using discounted cash flow methods to determine the implied fair value of goodwill. The difference between this implied fair value of the goodwill and its carrying value was recorded as impairment. The outcome of the analysis resulted in a non-cash expense for impairment of property and equipment, intangible assets and goodwill of $0.3 million, $1.2 million and $8.0 million, respectively, which was recorded during the third quarter of fiscal year 2018 as a separate line item in the Company's Condensed Consolidated Statements of Operations.

These assets are reported within the Company's Europe (primarily UK) reporting segment (Footnote 9). The inputs used to measure the estimated fair value of goodwill are classified as a Level 3 fair value measurement due to the significance of unobservable inputs based on company specific information.

The condensed consolidated financial statements include the accounts of 8x8 and its subsidiaries. All material intercompany accounts and transactions have been eliminated.

The significant accounting policies used in preparation of these condensed consolidated financial statements are disclosed in our Annual Report on Form 10-K for the fiscal year ended March 31, 2017 filed with the SEC on May 30, 2017, and there have been no changes to the Company's significant accounting policies during the nine months ended December 31, 2017, except as described in the "Recently Adopted Accounting Pronouncements" section below.

In July 2015, the FASB issued ASU 2015-11, Simplifying the Measurement of Inventory. Under this guidance, entities utilizing the first-in-first-out or average cost method should measure inventory at the lower of cost or net realizable value, where net realizable value is defined as the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. The adoption of this standard did not have a material impact to the Company's consolidated financial statements.

In March 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Stock-based Payment Accounting, which simplified certain aspects of accounting for stock-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, an option to recognize gross stock compensation expense with actual forfeitures recognized as they occur, as well as certain classifications on the statement of cash flows. The following is a summary of the impact the adoption of this ASU on the Company's consolidated financial statements:

7

• In recording stock-based compensation expense, the ASU allows companies to make a policy election as to whether they will include an estimate of awards expected to be forfeited or whether they will account for forfeitures as they occur. The Company has elected to continue to include an estimate of forfeitures in its stock-based compensation expense. Therefore, the ASU had no impact to the Company's consolidated financial statements.

• The ASU requires that employee taxes paid when an employer withholds shares for tax-withholding purposes be reported as financing activities in the consolidated statements of cash flows. Previously, the Company already included these cash flows in financing activities. Therefore, the adoption of the ASU had no impact.

• The ASU requires previously unrecognized excess tax benefits from stock-based compensation to be recognized on a modified retrospective basis. Unrecognized tax benefits result when a deduction for stock-based compensation does not reduce taxes payable. The impact of the ASU on the Company's deferred tax assets is disclosed in Note 7.

• The ASU also requires excess tax benefits to be presented as an operating activity on the statement of cash flows rather than as a financing activity on either a retrospective or prospective basis. The Company has elected to apply this provision of the ASU only on a prospective basis beginning with the first quarter of fiscal 2018.

In January 2017, the FASB issued ASU No. 2017-04, Intangibles and Other (Topic 350): Simplifying the Test for Goodwill Impairment, which eliminates the requirement to calculate the implied fair value of goodwill and instead requires an entity to record an impairment charge based on the excess of a reporting unit's carrying value over its fair value. This amendment is effective for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted. The Company has elected to early and prospectively adopt the provisions of ASU 2017-04 in the third quarter of fiscal 2018. The early adoption resulted in the Company recognizing goodwill impairment of the amount by which a reporting unit's carrying value exceeds its fair value.

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, along with amendments issued in 2015, 2016, and 2017, 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. This ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The new standard will become effective for the Company on April 1, 2018 and permits the use of either the full retrospective or modified retrospective transition method. The Company has preliminarily selected the modified retrospective method as the transition method.

The Company is in the middle stages of assessing the impact of the new standard on the Company's accounting policies, processes and system requirements. The Company has assigned internal resources and engaged third-party service providers to assist with the assessment and implementation. The Company currently believes the most significant impact will be to the allocation of consideration in a contract between product and service performance obligations and allocations to professional services performance obligations, as well as the deferral of certain sales commission as capitalized contract costs, which are expensed under current accounting principles.

In May 2017, the FASB issued ASU No. 2017-09, Compensation-Stock Compensation (Topic 718) - Scope of Modification Accounting. The amendments in the update provide guidance on types of changes to the terms or conditions of share-based payment awards that would be required to apply modification accounting under ASC 718, Compensation-Stock Compensation. The amendments are effective for annual reporting periods beginning after December 15, 2017 with early adoption permitted. Upon adoption, the amendment is not expected to have a material impact to the consolidated financial statements.

The Company has entered into a series of noncancelable capital lease agreements for data center and office equipment bearing interest at various rates.

With the exception of the new San Jose, California headquarter lease (Footnote 10), there were no material changes in our other commitments under contractual obligations, indemnification and other contingencies since March 31, 2017.

The Company, from time to time, is involved in various legal claims or litigation, including patent infringement claims that can arise in the normal course of the Company's operations. Pending or future litigation could be costly, could cause the diversion of management's attention and could upon resolution, have a material adverse effect on the Company's business, results of operations, financial condition and cash flows.

On August 22, 2017, the Company was named as a defendant in Venadium LLC v. 8x8 Inc., filed in the District of Delaware (Civil Action No. 1:17-cv-1176-LPS-CJB) along with five other defendants. Plaintiff Venadium LLC sued the Company for alleged patent infringement concerning alleged activities involving the Company's alleged methods for protecting computer programs. Based on the Company's subscription to certain patent risk management services, the Company settled the suit without needing to respond to the Complaint. The settlement amount was immaterial. On October 5, 2017, Plaintiff Venadium LLC filed a Notice of Voluntary Dismissal of Defendant (with prejudice) pursuant to Federal Rule of Civil Procedure 41(a)(1), thereby effecting formal dismissal of the suit without a Court Order. Accordingly, the lawsuit was resolved and withdrawn before the Company was obligated to respond to the Complaint.

On August 25, 2017, the Company was named as a defendant in Hublink, LLC v. 8x8 Inc., based on a Complaint filed in the District of Delaware (Civil Action No. 1:17-cv-1214-GMS) along with four other defendants. Plaintiff Hublink, LLC sued the Company for alleged patent infringement concerning alleged activities involving alleged implementations of the Company's videophone communications uses and/or offerings. Based on the Company's subscription to certain patent risk management services provided by a third party on October 31, 2017, Plaintiff Hublink, LLC filed a Notice of Voluntary Dismissal of Defendant (with prejudice) pursuant to Federal Rule of Civil Procedure 41(a)(1), thereby effecting formal dismissal of the suit without a Court Order. Accordingly, the lawsuit was resolved and withdrawn before the Company was obligated to respond to the Complaint.

6. STOCK-BASED COMPENSATION

The following table summarizes information pertaining to the stock-based compensation expense from stock options and stock awards (in thousands, except weighted-average grant-date fair value and recognition period):

During the nine months ended December 31, 2017, the Company issued restricted performance stock units (PSUs) to a group of executives with vesting that is contingent on both market performance and continued service. These PSUs vest (1) 50% on September 19, 2019 and (2) 50% on September 19, 2020, in each case subject to the performance of the Company's common stock relative to the Russell 2000 Index (the benchmark) during the period from grant date through such vesting date. A 2x multiplier will be applied to the total shareholder returns (TSR) for each 1% of positive or negative relative TSR, and the number of shares earned will increase or decrease at the end of each respective performance measurement period by 2% of the target numbers. In the event the Company's common stock performance is below negative 30% relative to the benchmark, no shares will be issued. These PSU grants are included in the restricted stock unit activity disclosure for the nine months ended December 31, 2017.

To value these market-based PSUs under the Equity Compensation Plans, the Company used a Monte Carlo simulation model on the date of grant. Fair value determined using the Monte Carlo simulation model varies based on the assumptions used for the expected stock price volatility, the correlation coefficient between the Company and the NASDAQ Composite Index, risk free interest rates, and future dividend payments.

Stock Repurchases

In May 2017, the Company's board of directors authorized the Company to purchase $25.0 million of its common stock from time to time under the 2017 Repurchase Plan (the "2017 Plan"). The 2017 Plan expires when the maximum purchase amount is reached, or upon the earlier revocation or termination by the board of directors. The remaining amount available under the 2017 Plan at December 31, 2017 was approximately $7.1 million.

The stock repurchase activity as of December 31, 2017 is summarized as follows (in thousands):

The total purchase price of the common stock repurchased and retired was reflected as a reduction to consolidated stockholders' equity during the period of repurchase.

The Company's effective tax rate was -400.7% and -2.2% for the three months ended December 31, 2017 and 2016, respectively. The difference in the effective tax rate and the blended U.S. federal statutory rate of 31.5% for the three months ended December 31, 2017 was due primarily to the recording of a full valuation allowance against our deferred tax assets in the period. The difference in the effective tax rate and the U.S. federal statutory rate of 34% for the three months ended December 31, 2016 was due primarily to the geographic mix of profits and losses.

The Company accounts for income taxes under the asset and liability approach and records deferred taxes based on differences between the financial statement basis and tax basis of assets and liabilities and available tax loss and credit carryforwards. In evaluating the ability to utilize deferred tax assets, management considers available evidence, both positive and negative, in determining future taxable income on a jurisdiction-by-jurisdiction basis. A valuation allowance against deferred tax assets is recorded if, based on the weight of the evidence, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Judgment is required in evaluating this ability to utilize deferred tax assets.

The Company recorded a full valuation allowance against its U.S. deferred tax assets in the period ended December 31, 2017, as it considered its cumulative loss in recent years to be substantial negative evidence for establishing the valuation allowance. As a result, the Company recognized a discrete tax expense of $71 million in the period. The Company will continue to assess the future realization of our deferred tax assets in each applicable jurisdiction and will adjust the valuation allowance accordingly.

As described in Note 1, the Company adopted the updated accounting standard for share-based payment accounting in first quarter of fiscal 2018. As a result, the Company recorded deferred tax assets of approximately $17.6 million with a corresponding increase to retained earnings related to previously unrecognized excess tax benefits. For the first quarter of fiscal 2018, the Company recognized approximately $0.4 million of excess tax benefits within the provision for income taxes. Additionally, the Company elected to prospectively apply the change in presentation of excess tax benefits as an operating activity on the statement of cash flows rather than as a financing activity. Accordingly, prior period classification of cash flows related to excess tax benefits were not adjusted.

The Act was enacted on December 22, 2017. Among numerous provisions, the Act reduces the U.S. federal corporate income tax rate from 35% to 21%, requires companies to pay a one-time transition tax on earnings of certain foreign subsidiaries that were previously tax deferred, and creates new taxes on certain foreign sourced earnings.

13

Deferred Tax Assets and Liabilities Impact

The Company remeasured certain deferred tax assets and liabilities based on the rates at which they are expected to reverse in the future, which is generally 21%. Accordingly, deferred tax assets decreased approximately $22 million in the period ended December 31, 2017. However, because the Company recorded a full valuation allowance, the decrease in deferred tax assets from the tax rate change was fully offset by a corresponding decrease in valuation allowance. As a result, there was no impact to the provision for income taxes due to the change in tax rate.

The one-time transition tax on foreign sourced earnings is based on the Company's total post-1986 earnings and profits (E&P) for which U.S. income taxes have been previously deferred. The Company did not record a one-time transition tax liability for its foreign subsidiaries as it does not have any untaxed foreign accumulated earnings as of the measurement dates.

The following is a reconciliation of the weighted average number of common shares outstanding used in calculating basic and diluted net loss per share (in thousands, except share and per share data):

The following shares attributable to outstanding stock options and stock awards were excluded from the calculation of diluted earnings per share because their inclusion would have been antidilutive (in thousands):

ASC 280, Segment Reporting, establishes annual and interim reporting standards for an enterprise's business segments and related disclosures about its products, services, geographic areas and major customers. Under ASC 280, the method for determining what information to report is based upon the way management organizes the operating segments within the Company for making operating decisions and assessing financial performance. The Company manages its operations primarily on a geographic basis. The Chief Executive Officer, the Chief Financial Officer, and the Chief Technology Officer or the Company's Chief Operating Decision Makers (CODMs), evaluate performance of the Company and make decisions regarding allocation of resources based on geographic results. The Company's reportable segments are the Americas and Europe. The Americas segment is primarily North America. The Europe segment is primarily the United Kingdom. Each operating segment provides similar products and services.

Revenues are attributed to each segment based on the ordering location of the customer or ship to location.

14

The following tables set forth the segment and geographic information for each period (in thousands):

Revenue is based upon the destination of shipments and the customers' service address. For the three and nine months ended December 31, 2017 and 2016, intersegment revenues of approximately $3.9 million and $1.8 million, and $10.6 million and $4.4 million, respectively, were eliminated in consolidation, and have been excluded from the table above.

On January 23, 2018, the Company entered into a 132-month lease to rent approximately 162,000 square feet for a new Company headquarters in San Jose, California. The lease term begins on January 1, 2019 or such earlier date on which the Company first commences to conduct business on the premises. The Company has the option to extend the lease for one additional five-year term, on substantially the same terms and conditions as the prior term but with the base rent rate adjusted to fair market value at that time.

Base rent is approximately $512,000 per month for the first 12 months of the lease, and the rate increases 3% on each anniversary of the lease commencement date. The Company is entitled to full rent abatement during the first 10 months of the lease term and 50% rent abatement during the next four months of the lease term. The Company is also responsible for paying its proportionate share of building and common area operating expenses, property taxes and insurance costs.

The Company is entitled to a one-time tenant improvement allowance of approximately $13.3 million, the full amount of which must be used within 12 months of the lease commencement date.

The Company has procured a standby letter of credit in the amount of $8.1 million (Footnote 5) for the benefit of the landlord, which may be drawn down in the event the Company defaults in the payment of its obligations under the lease.

We are a leading provider of global cloud communications and customer engagement solutions to over a million business users worldwide, empowering them to deliver exceptional customer experiences. Our suite of products weaves together unified cloud communications, conferencing, collaboration, and contact center solutions so today's organization can provide a positive customer and employee engagement experience by any channel and with real time access to systems of record and subject matter experts. Our technology provides one integrated management platform with one communication experience for employees and customers, as well as a real-time data analytics platform for constant learning and improvement.

Our fiscal year ends on March 31 of each calendar year. Each reference to a fiscal year in this report refers to the fiscal year ending March 31 of the calendar year indicated (for example, fiscal 2018 refers to the fiscal year ending March 31, 2018).

In the third quarter of fiscal year 2018, our service revenue from mid-market and enterprise customers grew 28% year-over year and represented 59% of total service revenue. New monthly recurring revenue (MRR) bookings from mid-market and enterprise customers was 65% of total bookings for the quarter and represented a 40% increase from the year ago quarter, reflecting strong demand for our services in our target market segments. Also, average monthly service revenue per mid-market and enterprise business customer (ARPU) increased 8% to a record $4,765, compared with $4,412 in the same period last year. The increase resulted from our success in selling a greater number of subscriptions to larger, more established customers.

In October 2017, we launched the new 8x8 Virtual Office Editions, in three product bundles: X2, X5 and X8. X8, our most unified offering, weaves together communications, collaboration with our contact center all into one solution. It includes an unlimited calling zone to 45 countries and a full suite of 8x8 Virtual Office features, such as HD voice, Virtual Office Meetings, HD Video, integrations with Salesforce, Zendesk and NetSuite CRM, Salesforce analytics for better and faster data insights, call recording, call quality reporting, and barge monitor whisper capabilities.

In order to position ourselves most effectively for our next phase of growth, we will pursue the following strategic initiatives:

First, we aligned global business units around our core market segments to optimize for growth. We bifurcated our internal sales operations into two separate sales operations - Small Business & eCommerce and Mid-market & Enterprise. These operations will align sales and delivery, connecting demand generation, services and support to drive revenue growth and profitability globally. Small Business & eCommerce will focus on our high-volume, transactional business, with the objective of accelerating growth and productivity through eCommerce and self-service. Midmarket & Enterprise will focus on creating leads through our internal demand generation portal and leveraging channel relationships to drive our consultative approach to our land and expand strategy for larger accounts in the North America, Europe, Middle East and Asia, and Asia-Pacific regions.

Second, we made executive appointments in our engineering, product, marketing and sales organizations to align with our new sales operations and accelerate adoption of our solutions across all market segments.

Third, we are transforming our product packaging and pricing through 8x8 Editions to streamline customer acquisition and leverage our integrated communications platform.

In the first fiscal quarter of 2018, we announced increased investments for sales and marketing expenses to accelerate the growth of our business in the mid-market and enterprise segments. We commenced these investments in the second quarter of fiscal 2018 and intend to incur them over several quarters. The precise timing of these additional expenditures, and the reporting periods in which they occur, will depend in part on when our management can implement the steps, particularly hiring additional personnel, necessary for achieving anticipated growth in our bookings and revenues. In addition, though we believe our new marketing and sales expenditures, and, to a lesser extent, our product development expenditures will help us achieve the bookings and revenue growth we are seeking, such growth in not assured, and will be impacted not only by the timing of those expenditures but also by our ability to effectively implement such plans and limit disruptions to our current operations while we do so. If we do not timely and effectively implement our new marketing, sales and product development plans, and productively utilize the increased expenditures, we may fail to realize the anticipated increase in growth rates in our bookings and revenues.

The discussion and analysis of our financial condition and results of operations are based upon our condensed consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses, and related disclosure of assets and liabilities. On an on-going basis, we evaluate our critical accounting policies and estimates. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. In the third fiscal quarter of 2018, we conducted an impairment test of the Company's goodwill. As a result of the test, we recorded impairment charges for goodwill and other assets in one of our reporting units in the United Kingdom totaling $9.5 million. Refer to Note 1 to our Condensed Consolidated Unaudited Financial Statements in Part I, Item 1.  We also recorded a full valuation allowance against our deferred tax assets of $71 million. Refer to Note 7 to our Condensed Consolidated Unaudited Financial Statements in Part I, Item 1. Actual results may differ from these estimates under different assumptions or conditions.

See Item 1 of Part I, "Financial Statements - Note 1 - Basis of Presentation - Recent Adopted Accounting Pronouncements."
