DivX, Inc. Reports First Quarter 2009 Financial Results

Emerging Product Categories Exceed 10% of Licensing Revenues for First Time

Balance Sheet Remains Strong with $138 Million or $4.24 per Share in

Cash and Investments

SAN DIEGO, CA — May 7, 2009 — DivX, Inc. (NASDAQ:DIVX), a digital media company, today announced results for the first quarter ended March 31, 2009.

The Company reported revenues for the first quarter of $18.7 million, comprised primarily of $18.6 million of technology licensing revenues. This compares to revenues of $25.0 million reported for the same period a year ago, which included $19.1 million of technology licensing revenues and $5.9 million of media and other distribution and services revenues. The decrease in non-licensing revenues was due to the transition to a new distribution agreement with Google that was signed in the first quarter and is expected to generate revenues in the second quarter of 2009.

“It has been an active start to the year for DivX,” stated Kevin Hell, Chief Executive Officer for DivX. “We saw meaningful traction beyond DVD players in Q1. For the first time, our emerging product categories represented over 10% of licensing revenue and we certified hundreds of new devices, including digital televisions, Blu-ray players and mobile handsets. In addition, we introduced a major new release of our software with the launch of DivX^® 7 supporting H.264, and we signed a new software distribution agreement with Google. With our industry-wide presence, global brand, strong business model, and a massive international community of DivX users, we remain confident in our ability to realize our vision of enabling consumers to enjoy high-quality video on any device and in any location.”

GAAP net loss in the first quarter of 2009 was approximately $1.4 million, or $0.04 per diluted share. DivX generated non-GAAP net income of approximately $1.2 million, or $0.04 per diluted share. Non-GAAP net income and earnings per diluted share exclude the following expenses: (1) non-cash share-based compensation of approximately $2.2 million ($1.3 million, or $0.04 per diluted share,

net of related taxes); (2) the scheduled amortization of purchased intangible assets related to the acquisition of MainConcept of $511,000 ($309,000, or $0.01 per diluted share, net of related taxes); (3) the foreign exchange impact on our intercompany loan of $313,000 ($189,000, or $0.01 per diluted share, net of related taxes); and (4) a non-cash charge of approximately $750,000, or $0.02 per diluted share, related to the change in value of certain deferred tax assets, due to a change in California income tax law enacted during the first quarter of 2009.

Dan Halvorson, Executive Vice President and Chief Financial Officer, added, “Despite the ongoing weakness in the worldwide consumer electronics market, DivX continues to deliver solid bottom line results through focused execution and rigid expense management. In addition, we continue to maintain a strong balance sheet with $137.8 million in cash and investments, or $4.24 per share, and continue to operate our business in a manner that is mindful of the global economic conditions, while investing where appropriate to capture market opportunities.”

Second Quarter 2009 Fiscal Outlook

The following table summarizes the Company’s financial guidance for the second quarter of 2009, its historic seasonably low quarter. The following estimates are based on the Company’s current business outlook as of the date of this press release:

Forward-Looking Statements

Statements in this press release that are not strictly historical in nature constitute “forward-looking statements.” Such statements include, but are not limited to, references to the expected growth and earnings potential of the DivX business, the Company’s position in the digital media space, uncertainties contributing to the macroeconomic climate in 2009, anticipated financial results for the second quarter 2009, and the uncertainty of anticipated revenue under the Google software distribution agreement. Such forward-looking statements involve known and unknown risks, uncertainties and other factors which may cause DivX’s actual results to be materially different from historical results or from any results expressed or implied by such forward-looking statements. These factors include, but are not limited to: the risk that customer use of DivX^® technology may not grow as anticipated; the risk that anticipated market opportunities may not materialize at expected levels, or at all; the risk that the Company’s activities may not result in the growth of profitable revenue; the uncertainties surrounding the macroeconomic climate, the risk that the Company’s financial performance for the second quarter 2009 may not meet expectations; the risk that the Google software distribution revenue may not meet expectations; risks and uncertainties related to the maintenance and strength of the DivX brand; DivX’s ability to penetrate existing and new markets; the effects of competition; DivX’s dependence on its licensees and partners; the effect of intellectual property rights claims; and other factors discussed in the “Risk Factors” section

3

of DivX’s most recent reports filed with the SEC. All forward-looking statements are qualified in their entirety by this cautionary statement. DivX is providing this information as of the date of this release and does not undertake any obligation to update any forward-looking statements contained in this release as a result of new information, future events or otherwise, other than as required under applicable securities laws.

Non-GAAP Financial Measures; GAAP EPS

DivX has provided in this release financial information that has not been prepared in accordance with GAAP. This information includes non-GAAP net income and diluted earnings per share, which excludes non-cash share-based compensation expense, the amortization of purchased intangible assets, the foreign exchange impact of our intercompany loan, and the non-cash charge related to the change in value of certain deferred tax assets. This non-GAAP information is provided to enhance the reader’s overall understanding of our current financial performance and prospects for the future. Specifically, we believe this information provides useful comparative data by excluding non-cash share-based compensation expense, which is not consistent from period-to-period. Also, we believe that the exclusion of amortization of purchased intangible assets, the foreign exchange impact of our intercompany loan, and the change in value of certain tax deferred assets provides useful comparative data by reflecting our business operations in a manner that is consistent with expected future operations. Management has historically used non-GAAP net income and non-GAAP earnings per diluted share when evaluating operating performance because we believe the exclusion of the items described above provides an additional measure of our core operating results and facilitates comparisons of our core operating performance against prior periods and our business model objectives. The presentation of this additional information should not be considered in isolation or as a substitute for results prepared in accordance with accounting principles generally accepted in the United States.

We will continue to evaluate the factors that might impact non-cash share-based compensation expense and accruals for income tax expense. The non-cash share-based compensation expense is expected to vary depending on the number of new grants issued to both current and new employees, and changes in the Company’s stock price, stock market volatility, expected option life, and risk-free interest rates (all of which are difficult to estimate). In addition, the factors that impact our deferred tax assets are expected to vary from period-to-period, also making our effective tax rate difficult to estimate.
