"Our focus on penetrating the mid-market with our differentiated suite of cloud communications and contact center services has clearly paid off and has positioned us as the provider of choice for this rapidly growing customer segment."

"Our record fourth quarter capped a very eventful year for the company as we posted strong revenue growth and non-GAAP net income quarter after quarter while successfully executing strategic initiatives such as the expansion of our mid-market customer base, the establishment of our global footprint in Europe and Asia, an acquisition in the United Kingdom and a $126 million capital raise," Verma continued.

"We have all of the elements in place, including compelling service differentiation, an international presence and a financial war chest, to further capture increasing worldwide market share for cloud communications and collaboration services, all designed to increase the business productivity of our customers," concluded Verma. "As we continue to expand both domestically and internationally in fiscal 2015, we plan to increase revenue by approximately 25% and maintain our non-GAAP net income as a percentage of revenue in the high-single digit range."

The Company has provided in this release financial information that has not been prepared in accordance with Generally Accepted Accounting Principles (GAAP). Management uses these non-GAAP financial measures internally in analyzing our financial results and believes they are useful to investors, as a supplement to GAAP measures, in evaluating the Company's ongoing operational performance. Management believes that the use of these non-GAAP financial measures provides an additional tool for investors to use in evaluating 8x8's ongoing operating results and trends and in comparing financial results with other companies in the industry, many of which present similar non-GAAP financial measures to investors.

Non-GAAP financial measures should not be considered in isolation from, or as a substitute for, financial information prepared in accordance with GAAP. Investors are encouraged to review the reconciliation of these non-GAAP financial measures to their most directly comparable GAAP financial measures below. A reconciliation of non-GAAP financial measures to their most directly comparable GAAP measures has been provided in the financial statement tables included below in this press release.

Non-GAAP net income and non-GAAP net income per share

We have defined non-GAAP net income as net income for GAAP plus non-cash tax adjustments, stock-based compensation, amortization of acquired intangible assets, acquisition-related costs, facility exit costs, gain on patent sale, gain on disposal of discontinued operations, management transition and gain on escrow settlement. We have excluded gain on patent sale, gain on disposal of discontinued operations and gain on escrow settlement because we consider these to have been isolated transactions and believe these are not reflective of our ongoing operations, and this reduces comparability of periodic operating results when these are included. Non-cash tax adjustments represent the differences between the amount of taxes we expect to pay and our GAAP tax provision each period. We have excluded stock-based compensation expense because it relies on valuations based on future events, such as the market price of our common stock, that are difficult to predict and are affected by market factors that are largely not within the control of management. Amortization of acquired intangible assets is excluded because it is a non-cash expense that we do not consider part of ongoing operations when assessing our financial performance, as it relates to accounting for certain purchased assets. We have excluded acquisition-related expenses, including expenses to exit an acquired facility, and management transition expenses because these expenses are attributable to non-routine transactions and are not part of ongoing operations that we measure for internal management reporting purposes. We define non-GAAP net income per share as non-GAAP net income divided by the weighted-average diluted shares outstanding. We define non-GAAP net income percentage of revenue as non-GAAP net income divided by revenue. The GAAP and non-GAAP weighted average number of diluted shares to calculate GAAP and non-GAAP earnings per share are the same. We believe that such exclusions facilitate comparisons to our historical operating results and to the results of other companies in the same industry, and provides investors with information that we use in evaluating management's performance on a quarterly and annual basis.

Management will host a conference call to discuss these results and other matters related to the Company's business today, May 21, 2014, at 4:30 pm EDT. The call is accessible via the following numbers and webcast links:

Participants should plan to dial in or log on ten minutes prior to the start time.
