comScore Reports Second Quarter 2012 Results

RESTON, VA –August 2, 2012 – comScore, Inc. (NASDAQ: SCOR), a leader in measuring the digital world, today announced financial results for the second quarter of 2012.

In the second quarter of 2012, comScore reported quarterly revenue of $60.3 million, an increase of 4% over the second quarter of 2011. Revenue growth in the second quarter of 2012 was adversely affected primarily by declines in the Company’s TV copy testing business and to a lesser degree by foreign currency fluctuations.

comScore entered the copy testing business in 2010 following the acquisition of ARSgroup, which offered survey based studies that help advertisers to pre-screen a TV commercial before putting it on the air. Recently, increased competition from suppliers who offer global offline research fielding capabilities encompassing countries with low Internet penetration has resulted in copy testing ceasing to be a strategic fit for comScore. Excluding the Company’s copy testing business which impacted revenue by 5% in the quarter, second quarter revenue measured on a non-GAAP pro forma basis would have increased 9% over the comparable period in 2011.

comScore also recorded a charge of $3.3 million for impairment of related TV copy testing intangible assets during the second quarter of 2012. GAAP loss before income taxes was ($6.4) million and GAAP net loss was ($6.6) million. This represents a GAAP net loss of ($0.20) per basic and diluted share. Non-GAAP net income was $13.1 million, or $0.37 per diluted share, an increase of 144% from the second quarter of 2011. Adjusted EBITDA was $9.6 million or 16% of revenue, compared to adjusted EBITDA of $11.1 million in the second quarter of 2011. Reconciliations of the foregoing historical non-GAAP financial measures to the most closely applicable GAAP financial measures are included in the financial tables attached to this press release.

Dr. Magid Abraham, comScore’s president and chief executive officer said, “We are disappointed that our revenue and adjusted EBITDA results were below expectations for the second quarter, largely due to the decline in our non-strategic copy testing business and a greater than expected effect of foreign currency fluctuations.

“However, we believe these factors mask the strength in new contract signings we are experiencing in our comprehensive portfolio of digital business analytics solutions. We are seeing accelerating adoption of our digital campaign measurement solutions, and we estimate that comScore has captured a strong share in the rapidly growing market for digital campaign ratings and performance measurement. In addition, our validated Campaign Essentials (vCE) service recently achieved accreditation from the Media Rating Council (MRC) for campaign validation including ad viewability measurement, a capability critical for delivering on an industry endorsed ‘viewable impression’ currency. Digital Analytix (DAx) is showing traction with customers attracted to its on–the-fly real-time analytics, scalable, big data architecture, and unique capabilities like DAx Monetization to help publishers more effectively monetize display advertising on their sites. In the mobile space, the recently launched Mobile Metrix 2.0 has been well received and has driven an uptick in

mobile analytics sales activity. Our core Audience Analytics family, led by Media Metrix 360 is performing well, and our overall renewal rate continued to exceed 90% on a constant dollar basis, while we also added 47 net new customers during the second quarter.

“Although newer products such as vCE and DAx are gaining traction, these products have a more extended revenue recognition ramp compared to products in our base business. While we remain optimistic as to our long-term growth outlook excluding the copy testing business, we are adjusting our full year revenue outlook to reflect these revenue recognition dynamics and greater anticipated foreign exchange impact due to the fragile economy in Europe, as well as the effects of declines in traditional TV copy testing revenues. At the same time, a strengthening market position, and robust bookings activity underscore our confidence in our longer-term growth and profitability prospects.”

Financial Outlook

comScore’s expectations for the third quarter of 2012 are outlined in the table below:

comScore’s expectations for full year 2012 are outlined in the table below:

Due to the high variability and difficulty in predicting certain items that affect GAAP net income, such as tax rates and stock price, comScore is unable to provide a complete reconciliation of Adjusted EBITDA to net income (loss) on a forward-looking basis without unreasonable efforts. However, a reconciliation of forward-looking Adjusted EBITDA to GAAP income (loss) before income taxes is set forth in the attachments to this press release.

Given the above discussion regarding our copy-testing business, we are also providing non-GAAP pro forma revenue and pro forma adjusted EBITDA guidance reconciliations that exclude this business in the attachments to this press release.

Non-GAAP Financial Measures

comScore reports all financial information required in accordance with generally accepted accounting principles (GAAP). comScore believes, however, that evaluating its ongoing operating results will be enhanced if it also discloses certain non-GAAP information because it is useful to understand comScore’s performance, as it excludes non-cash and other charges that many investors believe may obscure comScore’s on-going operating results.

For example, comScore uses non-GAAP net income, which excludes stock-based compensation, amortization of acquired intangible assets, impairment of intangible assets, impairment of marketable securities, costs from acquisitions, restructurings and other non-recurring items, the non-cash deferred tax provision, litigation and related settlement costs, and the purchase accounting impact on acquired deferred revenue. comScore reports non-GAAP EPS (diluted), which uses non-GAAP net income in lieu of GAAP net income in calculating earnings per share. Non-GAAP pro forma revenue excludes the estimated effects of revenue generated from ARS products. Adjusted pro forma EBITDA also excludes the estimated effects of operations related to ARS products.

In addition, comScore believes that adjusted EBITDA is a useful measure for investors to use to evaluate its operating performance. Adjusted EBITDA comprises non-GAAP net income further adjusted to exclude the cash tax provision, depreciation, interest income (expense) net, and costs not associated with ongoing operations, such as acquisition related, litigation and related settlement costs. A reconciliation of comScore’s GAAP results to these non-GAAP measures is included in the financial tables accompanying this release.

The company believes that adjusted EBITDA is an important indicator of the company’s operational strength and the performance of its business because it provides a link between profitability and operating cash flow. Adjusted EBITDA is also widely used by investors and analysts as a supplemental measure to evaluate the overall operating performance of companies in comScore’s industry. comScore’s management also uses adjusted EBITDA extensively as a measure of operating performance because it does not include the impact of items not directly resulting from its core operations. Moreover, the company’s management uses the measure for planning purposes, to allocate resources and to evaluate the effectiveness of the company’s business strategies and management’s performance.

The company believes that excluding certain costs from non-GAAP net income and EPS and from adjusted EBITDA provides a meaningful indication to investors of the expected on-going operating performance of the company. Specifically as it relates to acquisitions and restructurings, the exclusion of these costs reflects the expected benefits realized or to be realized upon the integration of acquired entities into comScore, and the realized benefits of the restructurings.

comScore’s management also uses free cash flow as a non-GAAP measure of the company’s operating cash flow less cash expenditures for capital spending and acquisition-related costs as a key indicator of the company’s operating cash flow performance.

Whenever comScore uses such historical non-GAAP financial measures, it provides a reconciliation of historical non-GAAP financial measures to the most closely applicable GAAP financial measure. Investors are encouraged to review the related GAAP financial measures and the reconciliation of these historical non-GAAP financial measures to their most directly comparable GAAP financial measure included in the financial tables accompanying this release. Although the company provides a reconciliation of historical non-GAAP financial measures, due to the high variability and difficulty in predicting certain items that affect net income, such as tax rates and stock price, comScore is unable to provide a complete reconciliation of adjusted EBITDA to net income on a forward-looking basis without unreasonable efforts. However, a reconciliation of forward-looking adjusted EBITDA to GAAP income (loss) before income taxes is set forth in the attachment to this press release.

These non-GAAP financial measures do not reflect a comprehensive system of accounting, differ from GAAP measures with the same captions and may differ from non-GAAP financial measures with the same or similar captions that are used by other companies. The use of certain non-GAAP financial measures requires management to make estimates and assumptions regarding amounts of assets and liabilities and the amounts of revenue and expense during the reporting periods. Significant estimates and assumptions are inherent in the analysis and the measurement of certain elements of non-GAAP financial measures such as the impact of purchase accounting on acquired deferred revenue and the amortization of deferred contract costs associated with acquired deferred revenue. comScore bases its estimates on historical experience and assumptions that it believes are reasonable. Actual results could differ from those estimates.
