	•		Revenues of $41.7 million
	•		GAAP diluted net income per share of $0.06 / Non-GAAP diluted net income per share of $0.09
	•		Bookings of $71.8 million

PHILADELPHIA, May 2, 2011 /PRNewswire-FirstCall/ — eResearchTechnology, Inc. (ERT), (Nasdaq: ERT - News) a global technology-driven provider of services and customizable medical devices to biopharmaceutical and healthcare organizations and the market leader for centralized cardiac safety and respiratory efficacy services in drug development, announced today results for the first quarter ended March 31, 2011. Unless otherwise noted, all comparative numbers refer to changes from the same period a year ago. The financial results include the results related to CareFusion Research Services (RS) commencing from its date of acquisition on May 28, 2010.

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 RS acquisition 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 2011

	•		Net revenues were $41.7 million for the first quarter of 2011 compared to $44.9 million for the fourth quarter of 2010 and $21.9 million a year ago. Revenues from RS were $18.9 million in the first quarter of 2011, compared to $20.0 million in the fourth quarter of 2010.
	•		GAAP gross margin percentage was 44.2% in the first quarter of 2011 compared to 43.9% for the fourth quarter of 2010 and 53.8% a year ago. Non-GAAP gross margin percentage was 48.7% in the first quarter of 2011 compared to 49.0% for the fourth quarter of 2010 and 53.8% a year ago.
	•		GAAP operating income margin percentage was 12.8% in the first quarter of 2011 compared to 11.6% for the fourth quarter of 2010 and 12.6% a year ago. Non-GAAP operating income margin percentage was 17.3% in the first quarter of 2011 compared to 18.5% for the fourth quarter of 2010 and 16.0% a year ago.
	•		GAAP net income was $3.1 million, or $0.06 per diluted share, in the first quarter of 2011 compared to $4.1 million, or $0.08 per diluted share, in the fourth quarter of 2010 and $1.8 million, or $0.04 per diluted share, a year ago. Non-GAAP net income was $4.5 million, or $0.09 per diluted share, in the first quarter of 2011 compared to $6.1 million, or $0.12 per diluted share, in the fourth quarter of 2010 and $2.2 million, or $0.05 per diluted share, a year ago.

	•		Cash flow from operations was $5.0 million in the first quarter of 2011, compared to $17.1 million in the fourth quarter of 2010 and $5.3 million a year ago.
	•		Cash and short-term investments totaled $29.7 million at March 31, 2011 compared to $30.4 million on December 31, 2010. ERT had $21.0 million in long-term debt as of March 31, 2011 and December 31, 2010.
	•		New bookings were $71.8 million in the first quarter of 2011 compared to $58.9 million for the fourth quarter of 2010 and $43.3 million a year ago.
	•		The gross book-to-bill ratio was 1.7 in the first quarter of 2011 compared to 1.3 in the fourth quarter of 2010 and 2.0 a year ago.
	•		Backlog was $318.6 million as of March 31, 2011 compared to $302.9 million as of December 31, 2010 and $182.7 million a year ago (which did not include RS). The annualized cancellation rate was 24.6% in the first quarter of 2011 compared to 16.6% in the fourth quarter of 2010 and 21.3% a year ago.

“We are very pleased with the record $71.8 million of bookings reported in this quarter,” commented Dr. Joel Morganroth. “This was driven by strong bookings using our integrated solution, which combines respiratory, cardiac safety, and ePRO to our customers. Our revenue level was slightly lower than expected due to a large TQT cancellation during the quarter. We also experienced higher cancellations in our respiratory business as three large studies were terminated by the sponsors. We managed to moderate our expenses as some of the 2011 planned hiring and other investments were delayed. Offsetting this was the negative impact of the foreign exchange rate changes, which resulted in a charge of approximately $0.01 per share. Overall, we believe we are off to a strong start for 2011.”

“I am also very excited to have Dr. Jeffrey Litwin appointed as our new President and Chief Executive Officer as previously announced earlier today,” continued Dr. Morganroth. “Jeff and I have worked together for many years, and he brings knowledge of the clinical research domain that is our core business and also experience in the adjacent markets of Phase IV safety surveillance and healthcare.”

2011 Guidance

The Company reaffirmed its previously-issued guidance for the full year of 2011. ERT expects net revenues of between $178 million and $188 million for 2011. ERT expects GAAP diluted net income per share to be between $0.30 and $0.40 for 2011 and non-GAAP diluted net income per share to be between $0.40 and $0.50 for the same period. For the second quarter ending June 30, 2011, ERT expects net revenues of between $43.0 million and $46.0 million, GAAP diluted net income per share to be between $0.05 and $0.08 and non-GAAP diluted net income per share to be between $0.08 and $0.11.

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, 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 its recent acquisition 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 incurred in 2010 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 incurred in 2010 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 2010 acquisition of RS 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.

These statements are subject to risks and uncertainties that could cause actual results to differ materially from those expressed or implied in the forward-looking statements. Factors that might cause such a difference include: unfavorable economic conditions; our ability to obtain new contracts and accurately estimate net revenues, our positive outlook for future bookings, variability in size, scope and duration of projects and internal issues at the sponsoring client; our ability to successfully integrate the RS or any future acquisitions; competitive factors in the market for our centralized services; changes in the bio-pharmaceutical and healthcare industries to which we sell our solutions; technological development; and market demand. There is no guarantee that the amounts in our backlog will ever convert to revenue.
