Rosetta Stone Inc. Announces Updated Guidance for the Third Quarter and Full Year 2009 and Discontinues Follow-On Offering

ARLINGTON, Va.--(Business Wire)--
Rosetta Stone Inc. (NYSE: RST), a leading provider of technology-based language
learning solutions, today announced updated guidance for the three months ending
September 30, 2009 and for the year ending December 31, 2009. The Company also
announced that it will not proceed with the previously announced public offering
of shares of its common stock at this time.

"Our revisions are primarily due to greater than expected operating expenses for
the quarter ending September 30, 2009," said Brian Helman, chief financial
officer of Rosetta Stone. "While we continue to have confidence in our sales
performance, we no longer believe that we will achieve the third quarter
profitability targets that we guided to on our previous earnings release."

"During the current quarter, the company has incurred higher sales and marketing
costs and higher product development costs than previously anticipated," stated
Mr. Helman. "In addition, in the ordinary course of business, we frequently test
new types of marketing media. In the current quarter, we experimented with a
significant amount of internet and television test marketing programs and we did
not expeditiously terminate certain of those programs that were not yielding
acceptable results. We also changed our media mix, increasing radio and
long-form television as a proportion of the mix, which resulted in lower than
expected returns during the current quarter."

Mr. Helman further stated, "Due to the success of Levels 4 and 5, which we just
released in English (US) and Spanish (Latin America) in May 2009, we have
accelerated product development expenses in order to expedite bringing four
additional languages to market in levels 4 and 5 prior to the 2009 holiday
season."

"We believe our business and fundamentals remain strong," said Tom Adams,
president and chief executive officer of Rosetta Stone. "Despite higher expenses
in July and August, we still expect to deliver strong financial results for 2009
and beyond. We continue to make the necessary investments in our business and
believe we are well positioned for long term growth."

The Company`s updated guidance is as follows:

Third Quarter of 2009
Previous Guidance Revised Guidance
Revenue $64.5 to $66.5 million No change
GAAP net income $6.5 to $6.9 million $4.9 to $5.3 million
GAAP net income per diluted share $0.30 to $0.32 $0.22 to $0.24
Non-GAAP net income per diluted share $0.33 to $0.35 $0.25 to $0.27
Adjusted EBITDA $13.2 to $13.7 million $10.4 to $10.8 million
Diluted weighted-average shares outstanding 21.6 million No change

Full Year 2009
Previous Guidance Revised Guidance

Revenue $245.0 to $248.0 million No change
GAAP net income $11.3 to $12.1 million $9.7 to $10.5 million
GAAP net income per diluted share $0.56 to $0.60 $0.48 to $0.52
Non-GAAP net income per diluted share $1.22 to $1.26 $1.14 to $1.18
Adjusted EBITDA $46.5 to $47.5 million $43.7 to $44.7 million
Diluted weighted-average shares outstanding 20.2 million No change

The above statements are based on current expectations. These statements are
forward-looking, and actual results may differ materially.

Non-GAAP Financial Measures

This press release contains guidance on expected non-GAAP financial measures,
including non-GAAP net income per share and adjusted EBITDA. These measures
differ from GAAP in that they exclude amortization primarily related to acquired
intangibles, stock-based compensation expenses, and IPO related compensation
expenses. Adjusted EBITDA is GAAP net income or loss plus interest expense,
income tax expense, depreciation, amortization, and stock-based and IPO related
compensation expenses. 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:

* 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.
* IPO related Compensation. Although the IPO related compensation was an
important aspect of compensation for the company`s key employees that played a
material role in the growth and success of the company, it was an award that was
triggered by the company`s initial public offering which took place on April 16,
2009.

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 as they reflect the exercise of judgments by management about which
expenses and 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. Rosetta Stone 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, and not to rely on any single financial measure
to evaluate the company's business.
