(1)Definitions and reconciliations for all non-GAAP measures are provided in this press release.

“Second quarter results reflected the beginnings of our efforts to improve profitability by better balancing the need to generate positive margins on the bottom line with investments to drive growth,” said Steve Swad, Rosetta Stone’s President and Chief Executive Officer.  Swad added, “We undertook a number of actions during the quarter that focused on resetting our cost structure to enable us to pursue profitable growth.  Some of these actions included reducing, and better managing, our media spending, continuing to optimize our distribution channels, streamlining our European operations and carrying out a modest headcount reduction, primarily in the U.S.  The end result was positive Adjusted EBITDA of $1.1 million, a $2.4 million improvement compared to last year’s second quarter result of negative $1.3 million.”

Swad added, “At our Investor Day in May of this year, I laid out my strategy and priorities for the company, which are i) leveraging our brand, ii) innovating our platform

and iii) expanding distribution. I believe that we are executing on that strategy and Rosetta Stone is making progress towards our goals.”

Second Quarter 2012 Operational and Financial Highlights

·                  Revenue decreased 9%:  Revenue decreased 9% to $60.8 million reflecting the rationalization of less efficient kiosks, lower sales internationally and a decline in the Institutional business because of the non-renewal of the Army and Marines contracts last year.

·                  Adjusted EBITDA:  Adjusted EBITDA for the second quarter was $1.1 million, an increase of $2.4 million from ($1.3) million in the second quarter of 2011.  The improvement in Adjusted EBITDA was predominantly driven by a reduction in sales and marketing expenses, including a decrease in media spending, as well as a decrease in general and administrative expenses.  Adjusted EBITDA in the quarter includes approximately $1.7 million of restructuring and other one-time costs.

·                  Net Income: Rosetta Stone recorded a net loss of $4.5 million in the second quarter 2012, compared to a net loss of $4.6 million in the second quarter of 2011.  Net loss per share was $0.22 unchanged from a net loss of $0.22 per share in the prior year period.

·                  Balance Sheet and Cash Flow:  Cash, cash equivalents and short-term investments were $120.4 million at June 30, 2012, an increase of $4.1 million compared with $116.3 million at December 31, 2011 and an increase of $5.2 million from the prior year period.  The company has no debt.  Net cash provided by operating activities in the quarter was $3.4 million compared with ($2.9) million a year ago.  Capital expenditures were $1.0 million.  Free cash flow for the quarter was $2.4 million, compared with ($5.8) million in the second quarter of 2011.

Financial Outlook

The company is providing the following update to its guidance for the full year 2012:

·                  Increasing the bottom end of the range for Adjusted EBITDA* to $6 million for a range of $6 million to $8 million with Adjusted EBITDA margin of approximately 2% to 3% compared with previous guidance of $5 million to $8 million.

·                  Capital expenditures of $8 million to $11 million

*Adjusted EBITDA excludes any potential expenses related to the previously disclosed lawsuit seeking to prevent Google Inc. from infringing upon Rosetta Stone’s trademarks, and any restructuring costs.

Non-GAAP Financial Measures

This press release contains the non-GAAP financial measure Adjusted EBITDA, which is GAAP net income or loss plus interest expense, income tax expense, depreciation, amortization and stock-based compensation expenses.  Adjusted EBITDA excludes any potential expenses related to the previously disclosed lawsuit seeking to prevent Google Inc. from infringing upon Rosetta Stone’s trademarks, and any restructuring costs. Adjusted EBITDA for prior periods has been revised to conform to current definition.  This press release also includes the non-GAAP financial measure “free cash flow,” which is cash flow from operations less cash used in purchases of property and equipment.  Management believes that these non-GAAP measures of financial results provide useful information to investors regarding certain financial and business trends relating to the company’s financial condition and results of operations. Management uses these non-GAAP measures to compare the company’s performance to that of prior periods for trend analyses, for purposes of determining executive incentive compensation, and for budgeting and planning purposes.  These measures are used in monthly financial reports prepared for management and in quarterly financial reports presented to the company’s board of directors.  Management 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 the company’s financial measures with other software companies, many of which present similar non-GAAP financial measures to investors.

Management typically excludes the amounts described above when evaluating the company’s operating performance and believes that the resulting non-GAAP measures are useful to investors and financial analysts in assessing the company’s operating performance due to the following factors:

3

·                  Amortization of Acquired Intangibles. Amortization costs and the related tax effects are fixed at the time of an acquisition, and then amortized over a period of several years after the acquisition and generally cannot be changed or influenced by management after the acquisition.

·                  Stock-based Compensation. Although stock-based compensation is an important aspect of compensation of the company’s employees and executives, stock-based compensation expense is generally fixed at the time of grant, then amortized over a period of several years after the grant of the stock-based instrument, and generally cannot be changed or influenced by management after the grant.  In addition, the impact of shares granted under these plans is considered in the company’s EPS calculation to the extent the shares are dilutive.

Management does not consider these non-GAAP measures in isolation or as an alternative to financial measures determined in accordance with GAAP.  The principal limitation of these non-GAAP financial measures is that they exclude significant expenses and income that are required by GAAP to be recorded in the company’s financial statements.  In addition, they are subject to inherent limitations, because they reflect the exercise of judgments by management about which expenses and items of income are excluded from these non-GAAP financial measures and may not be calculated in the same manner as other companies’ similarly titled non-GAAP measures.

In order to compensate for these limitations, management presents its non-GAAP financial measures in connection with its GAAP results.  The company urges investors to review the reconciliation of its non-GAAP financial measures to the comparable GAAP financial measures, which it includes in press releases announcing earnings information, including this press release, and not to rely on any single financial measure to evaluate the company’s business.

Reconciliation tables of the most comparable GAAP financial measures to the non-GAAP measures used in this press release are included at the end of this release.
