Exhibit 99.1

ERT Reports First Quarter 2012 Operating Results

PHILADELPHIA, May 7, 2012 /PRNewswire-FirstCall/ — eResearchTechnology, Inc. (ERT), (Nasdaq: ERT—News), a global technology-driven provider of health outcomes research services and customizable medical devices to biopharmaceutical sponsors and contract research organizations (CROs), announced results today for the first quarter ended March 31, 2012. Unless otherwise noted, all comparative numbers refer to changes from the same period a year ago.

This press release contains financial measures prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) and non-GAAP measures adjusted to exclude the impact of the amortization of the acquired intangibles and other assets and acquisition and other costs related to the acquisition of CareFusion Research Services (RS or German operations) as well as costs related to our proposed acquisition by Genstar Capital LLC (Genstar) and related income tax effects. A reconciliation of these GAAP and non-GAAP measures is found in the attached “Reconciliation of GAAP to Non-GAAP Information.”

Financial Highlights for the First Quarter of 2012

1

Use of Non-GAAP Financial Measures

In addition to GAAP financial measures, ERT uses certain non-GAAP financial measures that exclude charges related to the amortization of the RS acquired intangible and other assets and acquisition and other costs which are related to the RS acquisition, in 2011 an other-than-temporary impairment of marketable securities that we received in connection with the sale of our former EDC operations in 2009 and in 2012 costs related to our proposed acquisition by Genstar, and also their related income tax effects. ERT believes that these non-GAAP measures are useful to investors because this supplemental information facilitates comparisons of its operations from period to period and to the performance of other companies within its industry and assists in gaining a better understanding of its operating results and future prospects. ERT views amortization of acquired intangible and other assets related to the RS acquisition, which includes such items as the amortization of acquired customer backlog and technology, as items determined at the time of the acquisition. While ERT reviews the underlying value of these intangibles regularly for impairment, the amortization is an expense typically not affected by operations during any particular period and does not contribute to the operational performance in any particular period. ERT regards acquisition and other costs related to the RS acquisition and proposed acquisition by Genstar as a cost that does not recur on a regular basis.

ERT’s non-GAAP effective tax rates differ from its GAAP effective tax rates because of 1) the exclusion of the amortization of acquired intangible and other assets and acquisition and other costs related to its recent acquisition of RS, and 2) the income tax effect due to the difference between the GAAP and non-GAAP effective tax rate applied against the GAAP pre-tax income, primarily as a result of the acquisition costs and the other-than-temporary impairment charge not being deductible for income tax purposes. ERT excludes the impact of these discrete tax items from its non-GAAP income tax provision because it believes they are not indicative of the effective income tax rate of its ongoing business operations.

Management uses these non-GAAP financial measures, in addition to the measures prepared in accordance with GAAP, as the basis for measuring ERT’s operating performance, financial and operating decision-making, development of budgets, and comparing such performance to that of prior periods for the same reasons stated above. These non-GAAP financial measures are not meant to be considered superior to or a substitute for comparable financial measures prepared in accordance with GAAP. There are also limitations on the non-GAAP measures, including: 1) these non-GAAP measures do not have standardized meanings and may not be comparable to similar non-GAAP measures used by other companies, 2) acquisition and other costs related to ERT’s recent acquisition of RS and proposed acquisition by Genstar represent actual cash expenditures that are excluded from ERT’s non-GAAP measures, and 3) although amortization of acquired intangible and other assets does not directly impact ERT’s current cash position, such expense is amortized over their expected economic lives and does represent the declining value of the assets acquired, but this expense is excluded from ERT’s non-GAAP measures. ERT adjusts for these limitations by relying on these non-GAAP measures only as a supplement to its GAAP results.
