SUNNYVALE, CA -- May 19, 2010 -- 8x8, Inc. (Nasdaq: EGHT), provider of innovative business communications solutions, today announced financial operating results for its fiscal fourth quarter and year ended March 31, 2010.

Full-Year Financial Results

Net income for fiscal 2010 was $3.9 million or $0.06 per share compared with a net loss of $2.5 million or ($0.04) per share for fiscal 2009. Total revenue for fiscal 2010 was $63.4 million compared with $64.7 million for fiscal 2009. Revenue from business customers grew 21% year over year from $40.2 million in fiscal 2009 to $48.7 million in fiscal 2010 while revenue from residential customers declined 40% from $24.4 million to $14.7 million in fiscal 2010. Revenue from business customers accounted for 77% of the company's total annual revenue, compared with 62% of annual revenue in fiscal 2009.

Fourth Quarter Financial Results

Net income for the fourth quarter of fiscal 2010 was $1.1 million or $0.02 per share compared sequentially to net income of $1 million or $0.02 per share for the previous quarter and a net loss of $3.9 million or ($0.06) per share for the same period of fiscal 2009. Total revenue for the fourth quarter of fiscal 2010 was $15.9 million compared sequentially to $15.9 million for the previous quarter and $15.8 million for the same period of fiscal 2009. In the fourth quarter of fiscal 2010, 8x8 revenue from business customers grew to $13.4 million, a 6% increase over the prior quarter and 25% increase over the same period last year and accounted for 85% of total revenue in the fourth quarter of fiscal 2010 compared to 79% in the prior quarter and 68% in the same period last year. Revenue from residential customers declined 27% in the fourth quarter of fiscal 2010 to $2.4 million from $3.3 million in the prior quarter.

During the fourth quarter of fiscal 2010, 8x8 added a record 29,985 new business lines and services, up 14% from the prior quarter and 35% from the same period last year. Average lines and services per new business customer increased to a record 10.4 compared to 9.5 in the prior quarter and 8.0 in the same year ago period. 8x8 added 2,875 gross new business customers during the fourth quarter, compared with 2,785 customers in the prior quarter, and ended the fourth quarter of fiscal 2010 with a total of 20,428 business customers.

"8x8 continues to generate robust growth in its core business customer service revenue," said Bryan Martin, 8x8's Chairman and Chief Executive Officer. "As demonstrated by our performance of sequential business customer revenue growth over the past three years, we believe the impact of the current economic climate has been minimal on this revenue stream. We expect this trend to continue going forward, potentially enhanced through select acquisitions that can expand our product service offerings into our business customer base. Our ability to expand this recurring base of revenue has enabled us to generate predictable profitability and strengthen our balance sheet, positioning 8x8 for continued success in fiscal 2011 and beyond."

Balance Sheet Highlights

Cash and cash equivalents increased to $18.1 million in the fourth quarter of fiscal 2010 from $17.1 million in the previous quarter and $16.4 million in the same period of fiscal 2009.

Subsequent Events

In April 2010, 8x8 sold its wholly-owned French research and development subsidiary, 8x8 Europe, SARL, to Stonyfish, a privately-held company in Los Altos, California. 8x8 also invested $250,000 cash in the new venture and granted a non-exclusive license to certain 8x8 technology. 8x8 will own 17% of Stonyfish following its initial round of external fundraising. All 8x8 research and development activities will remain at the Company's Sunnyvale, California headquarters under the leadership of 8x8 Chief Technology Officer Ramprakash Narayanaswamy.

In May 2010, 8x8 acquired Central Host, Inc., a Los Gatos, California company, for $1.6 million in a combination of cash and unregistered 8x8 common stock. Central Host provides customized, high-performance, managed hosting and cloud-based computing solutions targeted at small and medium sized enterprises. Central Host has relocated to 8x8's Sunnyvale, California headquarters and will combine its operations with 8x8's existing Network Operations Center (NOC), sales and customer service operations. Central Host's services compliment the current suite of hosted business communication services 8x8 offers to its more than 20,000 business customers.

"8x8 continues to expand its portfolio of hosted, profitable services for small businesses with the acquisition of Central Host," added Mr. Martin. "Central Host has built a loyal customer base and provides 8x8 with differentiated IT hosting services, which we will market to both existing and new business customers, further expanding our technological lead in the marketplace."

(1)	Includes 1,154 "Find me, Follow me" and 40 8x8 Virtual Office customers acquired in the second quarter of fiscal 2009 from Avtex Solutions, LLC ("Avtex").
(2)	Business customer churn is calculated by dividing the number of business customers that terminated (after the expiration of the 30-day trial) during that period by the simple average number of business customers during the period and dividing the result by the number of months in the period. The simple average number of business customers during the period is the number of business customers on the first day of the period plus the number of business customers on the last day of the period divided by two.
(3)	Business customers are defined as customers paying for service. Customers that have prepaid for their first month of service and are currently in the 30-day trial period are considered to be customers that are paying for service.
(4)	Business customer average monthly service revenue per customer is service revenue from business customers in the period divided by the number of months in the period divided by the simple average number of business customers during the period.
(5)	Total (business and residential) subscriber acquisition cost per service is defined as the combined costs of advertising, marketing, promotions, commissions and equipment subsidies during the period divided by the number of gross services added during the period.
(6)	Business subscriber acquisition cost per service is defined as the combined costs of advertising, marketing, promotions, commissions and equipment subsidies for business services sold during the period divided by the number of gross business services added during the period. The addition of 1,154 Avtex customers that migrated to 8x8 in the second fiscal quarter of 2009 but subscribed to "Find me, Follow me" services rather than 8x8 Virtual Office service, and the $79,230 in expense related to the acquisition of these 1,154 customers, is excluded from this calculation.
(7)	Business customer subscriber acquisition cost is business subscriber acquisition cost per service times the average number of services subscribed to per business customer.
