(Nasdaq:BSFT), the leading global provider of software that enables fixed-line, mobile and cable service providers to deliver real time communications, voice and multimedia, services over their IP-based networks, today announced financial results for the quarter and year ended December 31, 2010.

	•		Total revenue increased 61% sequentially and 85% year-over-year to $35.8 million
	•		License revenue increased 64% sequentially and 97% year-over-year to $21.1 million

	•		GAAP diluted EPS increased to $0.41 per common share; Non-GAAP diluted EPS increased to $0.44 per common share

Results for the quarter ended December 31, 2010

Total revenue rose to a record $35.8 million in the fourth quarter of 2010, an increase of 85% compared to $19.3 million in the fourth quarter of 2009 and an increase of 61% compared to $22.3 million in the third quarter of 2010.

Net income for the fourth quarter of 2010 was $11.2 million, or $0.41 per diluted common share, compared to net income of $0.4 million, or $0.05 per diluted common share in the fourth quarter of 2009. GAAP results for the fourth quarter of 2010 included $0.8 million of non-cash stock-based compensation expense and $0.2 million of amortization expense related to acquired intangible assets.

On a non-GAAP basis, net income in the fourth quarter of 2010 was $12.2 million or $0.44 per diluted common share, compared to non-GAAP net income of $1.0 million, or $0.07 per diluted common share, in the fourth quarter of 2009. Non-GAAP net income for these periods excludes the impact of non-cash stock-based compensation expense and amortization expense related to acquired intangible assets.

Management Commentary

“BroadSoft delivered another strong quarter driven by the expanding adoption of our hosted unified communications and SIP trunking applications,” said Michael Tessler, president and chief executive officer, BroadSoft. “We continue to innovate and extend our technology and market leadership in the emerging market for voice application servers. In addition to our recently introduced BroadCloud service delivery platform, we announced MobileMxD, an integrated suite of consumer and enterprise UC services optimized for 4G networks. With MobileMxD, we believe mobile operators will be able to quickly introduce new revenue generating services to monetize their LTE investments.”

“In the fourth quarter, we achieved a 64% sequential increase in license revenue while growing our deferred revenue balance by $5.0 million quarter over quarter” said Jim Tholen, chief financial officer, BroadSoft. “Moreover, our margins reached the highest levels in company history, with gross margins expanding for the third quarter in a row, to 86% on a non-GAAP basis and 85% on a GAAP basis, while our income from operations as a percent of total revenue rose to 36% on a non-GAAP basis, and 34% on a GAAP basis, in the fourth quarter. In addition, we generated $9.0 million in cash flow from operations during the fourth quarter and ended the year with cash, cash equivalents, and marketable securities totaling $65.9 million.”

Results for the year ended December 31, 2010

For the full year, total revenue was $95.6 million, compared to $68.9 million in 2009, reflecting year over year growth of 39%.

Net income for the full year 2010 was $8.0 million, or $0.49 per basic common share and $0.32 per diluted common share, compared to a net loss of $7.8 million, or $(1.25) per basic and diluted common share in 2009. GAAP results in 2010 included $3.0 million of non-cash stock-based compensation expense and $0.8 million of amortization expense related to acquired intangible assets.

On a non-GAAP basis, net income for the full year 2010 was $11.8 million or $0.53 per basic common share and $0.48 per diluted common share, compared to a non-GAAP net loss of $3.4 million, or $(0.18) per basic and diluted common share in 2009. Non-GAAP net income (loss) for these periods excludes the impact of non-cash stock-based compensation expense and amortization expense related to acquired intangible assets and the pro forma conversion of the redeemable convertible preferred stock.

Guidance

For the first quarter of 2011, BroadSoft anticipates revenue of $27.0 to $29.0 million. The Company expects to achieve first quarter earnings on a non-GAAP basis of $0.04 to $0.11 per diluted common share and on a GAAP basis, $0.00 to $0.07 per diluted common share.

For the full year 2011, BroadSoft expects revenue of $116.0 to $120.0 million. The Company expects to achieve full year earnings on a non-GAAP basis of $0.56 to $0.66 per diluted common share and on a GAAP basis, $0.35 to $0.45 per diluted common share.

Use of Non-GAAP Financial Measures

BroadSoft has provided in this release, and will provide on this afternoon’s teleconference, financial information that has not been prepared in accordance with generally accepted accounting principles, or GAAP. BroadSoft uses these non-GAAP financial measures internally in analyzing its financial results and believes they are useful to investors, as a supplement to GAAP measures, in evaluating BroadSoft’s ongoing operational performance. BroadSoft’s management regularly uses these non-GAAP financial measures to understand and manage its business and believes that these non-GAAP financial measures provide meaningful supplemental information regarding the Company’s performance by excluding certain non-cash expenses, and may include additional adjustments for items that are infrequent in nature. BroadSoft believes that the use of these non-GAAP financial measures provides an additional tool for investors to use in evaluating ongoing operating results and trends and in comparing its financial results with other companies in BroadSoft’s industry, many of which present similar non-GAAP financial measures to investors. A reconciliation of the non-GAAP financial measures included in this release and to be discussed on this afternoon’s teleconference to the most directly comparable GAAP financial measures is set forth below.

Non-GAAP net income (loss) and net income (loss) per share. We define non-GAAP net income (loss) as net income (loss) plus stock-based compensation expense and amortization expense related to acquired intangible assets. We define non-GAAP income (loss) per share as non-GAAP net income (loss) divided by the weighted average shares outstanding. Also, in calculating non-GAAP net income (loss) per share for the three months ended December 31, 2009 and the years ended December 31, 2010 and December 31, 2009, we adjusted the GAAP weighted average shares outstanding to include shares of redeemable convertible preferred stock on an “as-if-converted to common stock” basis. We consider these non-GAAP financial measures to be useful metrics for management and our investors because they exclude the effect of certain non-cash expenses so that management and our investors can compare BroadSoft’s core business operating results over multiple periods.

Non-GAAP gross margin, license gross margin and maintenance and professional services gross margin. We define non-GAAP gross margin as gross margin plus stock-based compensation expense and amortization expense related to acquired intangible assets. We consider non-GAAP gross margin to be a useful metric for management and our investors because it excludes the effect of certain non-cash expenses so that management and its investors can compare BroadSoft’s sales margins over multiple periods. Where we provide further breakdown of non-GAAP gross margin between license, and maintenance and professional services, we add back the stock-based compensation expense and amortization expense, as applicable, to the related gross margin.

Non-GAAP income (loss) from operations. We define non-GAAP income (loss) from operations as income (loss) from operations plus stock-based compensation expense and amortization expense related to acquired intangible assets. We consider non-GAAP income (loss) from operations to be a useful metric for management and our investors because it excludes the effect of certain non-cash expenses so that management and our investors can compare BroadSoft’s core business operating results over multiple periods. Where we provide further breakdown of non-GAAP operating expenses for sales and marketing, research and development and general and administrative, we deduct stock-based compensation expense included in the applicable expense item.

The presentation of non-GAAP net income (loss), non-GAAP net income (loss) per share, non-GAAP gross margin, non-GAAP income (loss) from operations and other non-GAAP financial measures in this release and on this afternoon’s teleconference is not meant to be a substitute for “net income (loss),” “net income (loss) per share,” “gross margin,” “income (loss) from operations” or other financial measures presented in accordance with GAAP, but rather should be evaluated in conjunction with such data. Our definition of “non-GAAP net income (loss),” “non-GAAP net income (loss) per share,” “non-GAAP gross margin,” “non-GAAP income (loss) from operations” and other non-GAAP financial measures may differ from similarly titled non-GAAP measures used by other companies and may differ from period to period. In reporting non-GAAP measures in the future, management may make other adjustments for expenses and gains that it does not consider reflective of core operating performance in a particular period and may modify “non-GAAP net income (loss),” “non-GAAP net income (loss) per share,” “non-GAAP gross margin,” “non-GAAP income (loss) from operations” and such other non-GAAP measures by excluding these expenses and gains.
