NIELSEN REPORTS FIRST QUARTER 2012 RESULTS

New York, USA – April 25, 2012 – Nielsen Holdings N.V. (NYSE: NLSN), a leading global provider of information and insights into what consumers buy and watch, today announced financial results for the first quarter ended March 31, 2012.

“Nielsen delivered solid first quarter results, with continued growth in developing markets and steady performance across our businesses,” said David Calhoun, Chief Executive Officer of Nielsen. “We have great confidence about our investments in growth, our ability to deliver value to clients and our outlook for 2012.”

First Quarter 2012 Operating Results

Revenues for the first quarter increased 3% to $1,340 million, or 4% on a constant currency basis compared to the first quarter of 2011. Growth was driven by a 3% increase within our Buy segment (5% on a constant currency basis), a 3% increase within our Watch segment (3% on a constant currency basis) and a 9% increase within our Expositions segment (9% on a constant currency basis).

Adjusted EBITDA for the first quarter increased 4% to $332 million, or 5% on a constant currency basis compared to the first quarter of 2011, as we continue to strategically reinvest in the expansion of our services globally.

Net income for the first quarter was $25 million compared to a net loss of $181 million in the first quarter of 2011, driven primarily by the first quarter 2011 charges of $206 million, net of tax, associated with the IPO. Net income per share, on a diluted basis, was $0.07 compared to a net loss per share of $0.55 in the first quarter of 2011.

Adjusted Net Income for the first quarter increased to $113 million compared to $64 million in the first quarter of 2011, driven primarily by a net $34 million reduction in interest expense resulting from debt retirements and growth in Adjusted EBITDA. Adjusted Net Income per share was $0.30 compared to $0.19 in the first quarter of 2011.

Financial Position

As of March 31, 2012, cash balances were $295 million and gross debt was $6,568 million, excluding the $288 million mandatory convertible subordinated bonds due 2013. Net debt

(gross debt less cash and cash equivalents) at the end of the quarter was $6,273 million and our net debt leverage ratio was 4.0x. Capital expenditures were $82 million for first quarter of 2012 as compared to $52 million for the first quarter of 2011.

In February 2012, we executed a new $1.2 billion five-year term loan, the proceeds from which were applied to refinance the majority of our existing 2013 bank maturities. As of March 31, 2012, more than 80% of our debt portfolio has a maturity of 2016 or beyond.

In March 2012, we completed a secondary public offering of 34.5 million shares of our common stock on behalf of the selling stockholders, primarily comprised of the Sponsor group. All proceeds were received by the selling stockholders and the offering did not have a significant impact on our operating results or financial position.

Results of Operations—(Three Months Ended March 31, 2012 and 2011)

The following table sets forth, for the periods indicated, the amounts included in our Condensed Consolidated Statements of Operations:

Page 3 of 6

Certain Non-GAAP Measures

We use the non-GAAP financial measures discussed below to evaluate the results of our operations. We believe that the presentation of these non-GAAP measures provides useful information to investors regarding financial and business trends related to our results of operations and that when this non-GAAP financial information is viewed with our GAAP financial information, investors are provided with a more meaningful understanding of our ongoing operating performance. None of the non-GAAP measures presented should be considered as an alternative to net income or loss, operating income or loss, cash flows from operating activities, total indebtedness or any other performance measures of operating performance, liquidity or indebtedness derived in accordance with GAAP. These non-GAAP measures have important limitations as analytical tools and should not be considered in isolation or as substitutes for an analysis of our results as reported under GAAP. Our use of these terms may vary from the use of similarly-titled measures by others in our industry due to the potential inconsistencies in the method of calculation and differences due to items subject to interpretation

Constant Currency Presentation

We evaluate our results of operations on both an as reported and a constant currency basis. The constant currency presentation, which is a non-GAAP measure, excludes the impact of fluctuations in foreign currency exchange rates. We believe providing constant currency information provides valuable supplemental information regarding our results of operations, consistent with how we evaluate our performance. We calculate constant currency percentages by converting our prior-period local currency financial results using the current period exchange rates and comparing these adjusted amounts to our current period reported results.

Adjusted EBITDA and Adjusted Net Income

We define Adjusted EBITDA as net income or loss from our consolidated statements of operations before interest income and expense, income taxes, depreciation and amortization, restructuring charges, goodwill and intangible asset impairment charges, stock compensation expense and other non-operating items from our consolidated statements of operations as well as certain other items considered unusual or non-recurring in nature. Adjusted EBITDA is not a presentation made in accordance with GAAP, and our use of the term Adjusted EBITDA may vary from the use of similarly-titled measures by others in our industry due to the potential inconsistencies in the method of calculation and differences due to items subject to interpretation. We use Adjusted EBITDA to measure our performance from period to period both at the consolidated level as well as within our operating segments, to evaluate and fund incentive compensation programs and to compare our results to those of our competitors.

We define Adjusted net income as net income or loss from our consolidated statements of operations before income taxes, depreciation and amortization associated with acquired tangible and intangible assets, restructuring charges, goodwill and intangible asset impairment charges, other non-operating items from our consolidated statements of operations and certain other items considered unusual or non-recurring in nature, reduced by cash paid for income taxes. Also excluded from Adjusted net income is interest expense attributable to the mandatory convertible subordinated bonds due 2013. Adjusted Net Income per share of common stock presented on a diluted basis includes potential common shares associated with stock-based compensation plans that may have been considered anti-dilutive in accordance with GAAP. The amount also includes the weighted-average amount of shares of common stock convertible associated with the mandatory convertible bonds based upon the average price of our common stock during the period.

Adjusted net income and Adjusted net income per share of common stock are not presentations made in accordance with GAAP.

The below table presents a reconciliation from net income to Adjusted EBITDA and Adjusted net income and a reconciliation from weighted-average shares outstanding on a GAAP basis to diluted shares outstanding for the three months ended March 31, 2012 and 2011, respectively:

Net Debt and Net Debt Leverage Ratio

The net debt leverage ratio is defined as net debt (gross debt less cash and cash equivalents) as of the balance sheet date divided by Adjusted EBITDA for the twelve months then ended. Net debt and the net debt leverage ratio are commonly used metrics to evaluate and compare leverage between companies and are not presentations made in accordance with GAAP. The calculation of net debt and the net debt leverage ratio as of March 31, 2012 is as follows:
