GAITHERSBURG, MD, May 9, 2011 – BroadSoft, Inc. (Nasdaq:BSFT), the leading global provider of software that enables fixed-line, mobile and cable service providers to deliver real time voice and multimedia communications services over their IP-based networks, today announced financial results for the quarter ended March 31, 2011.

Financial Highlights for the First Quarter of 2011

   •   Total revenue increased 67% year-over-year to $29.7 million

   •   License revenue increased 73% year-over-year to $15.2 million

•

GAAP gross profit increased to 80% of total revenue; non-GAAP gross profit increased to 81% of total revenue

•

GAAP income from operations increased to $4.1 million; non-GAAP income from operations increased to $5.5 million

•

GAAP diluted EPS increased to $0.13 per common share; non-GAAP diluted EPS increased to $0.18 per common share

Results for the three months ended March 31, 2011

Total revenue rose to $29.7 million in the first quarter of 2011, an increase of 67% compared to $17.8 million in the first quarter of 2010.

Net income for the first quarter of 2011 was $3.7 million, or $0.13 per diluted common share, compared to a net loss of $(2.6) million, or $(0.41) per basic and diluted common share, in the first quarter of 2010. GAAP results for the first quarter of 2011 included $1.1 million of non-cash stock-based compensation expense and $0.2 million of amortization expense for acquired intangible assets.

On a non-GAAP basis, net income in the first quarter of 2011 was $5.0 million, or $0.18 per diluted common share, compared to a non-GAAP net loss of $(2.1) million, or $(0.11) per basic and diluted common share, in the first quarter of 2010. Non-GAAP net income for these periods excluded the impact of non-cash stock-based compensation expense and amortization expense for acquired intangible assets, and for the three months ended March 31, 2010, the loss per basic and diluted share included an adjustment for the preferred stock conversion.

Management Commentary

“BroadSoft is off to a great start in 2011, delivering record first quarter financial results driven by continued strong demand for our hosted unified communications and SIP trunking applications from both new and existing customers,” said Michael Tessler, president and chief executive officer, BroadSoft. “We are confident that our leadership position in the market for voice application servers, combined with accelerating demand from our service provider customers, will lead to solid growth in our business in 2011.”

“We posted a strong first quarter, marked by a 73% increase in license revenue compared to the year ago period led by robust demand from our North American service provider customers,” said Jim Tholen, chief financial officer, BroadSoft. “Moreover, our margins and profitability improved significantly relative to last year’s first quarter. In addition, we generated $3.1 million in cash flow from operations during the first quarter and ended the quarter with cash, cash equivalents and marketable securities totaling $69.8 million.”

Guidance

For the second quarter of 2011, BroadSoft anticipates revenue of $28.0 to $29.0 million, which represents growth of 41% to 46% over second quarter 2010 revenue of $19.8 million. The Company expects to achieve second quarter earnings on a non-GAAP basis of $0.09 to $0.11 per

diluted common share and on a GAAP basis, $0.03 to $0.05 per diluted common share.

For the full year 2011, BroadSoft is increasing its guidance and now expects revenue of $121.0 to $125.0 million, reflecting growth of 27% to 31% over 2010 revenue of $95.6 million. The Company anticipates full year 2011 earnings on a non-GAAP basis of $0.67 to $0.77 per diluted common share and on a GAAP basis, $0.45 to $0.55 per diluted common share.

The above second quarter and full year guidance does not reflect the impact of a potential release of a tax valuation allowance relating to net deferred tax assets. The Company currently expects this release could occur as early as the second quarter of 2011 and that the release of the valuation allowance would be recorded as an income tax benefit, which would significantly increase the Company’s reported net income for the period in which the release occurs.

Use of Non-GAAP Financial Measures

BroadSoft has provided in this release, and will provide on this morning’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 morning’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 for 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 March 31, 2010, 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 services gross margin. We define non-GAAP gross margin as gross margin plus stock-based compensation expense and amortization expense for 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 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 for 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 morning’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.
