RALEIGH, NC — PRA Health Sciences, Inc. (NASDAQ: PRAH) today reported financial results for the quarter ended March 31, 2015.

For the three months ended March 31, 2015, the company's service revenues were $332.0 million, which represents growth of 7%, or $20.6 million, compared to the first quarter of 2014 at actual foreign exchange rates. On a constant currency basis, service revenue grew $30.6 million, an increase of 10% compared to the first quarter of 2014.

Net new business for the quarter ended March 31, 2015 was $398.0 million representing a book-to-bill ratio of 1.2 for the period. This net new business contributed to an ending backlog of $2.2 billion at March 31, 2015.

"We are off to a strong start in 2015 and I am pleased by our first quarter financial results that demonstrate a continuation of the solid momentum we achieved in 2014," said Colin Shannon, chief executive officer. "We continue to execute consistently across all of our businesses, which resulted in 10% revenue growth on a constant currency basis in the first quarter. We continue to win new business, as evidenced by our strong book-to-bill ratio and our $2.2 billion of backlog, the highest level in our company's history.

"In addition, we were recently honored as the "International Clinical Company of the Year" by PharmaTimes, which is recognition of our dedication to our clients and the exceptional talent and caliber of our employees."

Direct costs were $219.0 million during the three months ended March 31, 2015 compared to $215.2 million for the first quarter of 2014. Direct costs were 66.0% of service revenue during the first quarter of 2015 compared to 69.1% of service revenue during the first quarter of 2014. The decrease in direct costs as a percentage of service revenue is primarily related to the favorable impact from foreign currency exchange rate fluctuations.

Selling, general and administrative expenses were $60.8 million during the three months ended March 31, 2015 and 2014. Selling, general and administrative costs were 18.3% of service revenue during the first quarter of 2015 compared to 19.5% of service revenue during the first quarter of 2014. The decrease in selling, general and administrative expenses is primarily related to our continued leveraging of our selling and administrative functions.

Reported EBITDA on a GAAP basis was $59.8 million, representing an increase of 99.3% compared to the first quarter of 2014. Adjusted EBITDA was $55.7 million for the three months ended March 31, 2015, representing growth of 40.3% compared to the first quarter of 2014.

Reported GAAP net income was $17.2 million and reported GAAP diluted net income per share was $0.27 for the three months ended March 31, 2015, increases of 272% and 208%, respectively, when compared to the first quarter of 2014.

Adjusted Net Income was $25.8 million for the three months ended March 31, 2015, representing growth of 190% compared to the first quarter of 2014. Adjusted Net Income per share was $0.41 for the three months ended March 31, 2015, representing growth of 86% compared to the first quarter of 2014.

Reconciliations of our non-GAAP measures, including Adjusted EBITDA, Adjusted Net Income and Adjusted Net Income per share to the corresponding GAAP measures are attached to this press release.

Actual results may differ materially from the Company's expectations due to a number of factors, including that most of the Company's contracts may be terminated on short notice, and that the Company may be unable to maintain large customer contracts or to enter into new contracts; the historical indications of the relationship of backlog to revenues may not be indicative of their future relationship; the market for the Company's services may not grow as the Company expects; the Company may under price contracts or overrun its cost estimates, and if the Company is unable to achieve operating efficiencies or grow revenues faster than expenses, operating margins will be adversely affected; the Company may be unable to maintain information systems or effectively update them; customer or therapeutic concentration could harm the Company's business; the Company's business is subject to risks associated with international operations, including economic, political and other risks; government regulators or customers may limit the scope of prescription or withdraw products from the market, and government regulators may impose new regulations affecting the Company's business; the Company may be unable to successfully develop and market new services or enter new markets; the Company's failure to perform services in accordance with contractual requirements, regulatory standards and ethical considerations may subject it to significant costs or liability, damage its reputation and cause it to lose existing business or not receive new business; the Company's services are related to treatment of human patients, and it could face liability if a patient is harmed; the Company has substantial indebtedness and may incur additional indebtedness in the future, which could adversely affect the Company's financial condition; and other factors that are set forth in the Company's filings with the Securities and Exchange Commission, including our most recent Annual Report on Form 10-K filed with the SEC on March 2, 2015.

Use of Non-GAAP Financial Measures

This press release includes Adjusted EBITDA, Adjusted Net Income and Adjusted Net Income per share, each of which are financial measures not prepared in accordance with accounting principles generally accepted in the United States ("GAAP"). Management believes that these measures are more indicative of our operating results as they exclude certain items whose fluctuation from period-to-period do not necessarily correspond to changes in the operating results of our business. As a result, management and our board of directors regularly use EBITDA and Adjusted EBITDA as a tool in evaluating our operating and financial performance and in establishing discretionary annual bonuses. Adjusted EBITDA is also the basis for covenant compliance EBITDA, which is used in certain covenants in the credit agreement governing our senior secured credit facilities and the indenture governing the senior notes. In addition, management believes that EBITDA, Adjusted EBITDA and Adjusted Net Income (including diluted adjusted net income per share) facilitate comparisons of our operating results with those of other companies by backing out of GAAP net income items relating to variations in capital structures (affecting interest expense), taxation, and the age and book depreciation of facilities and equipment (affecting relative depreciation expense), which may vary for different companies for reasons unrelated to operating performance. We believe that EBITDA, Adjusted EBITDA and Adjusted Net Income (including diluted adjusted net income per share) are frequently used by securities analysts, investors, and other interested parties in the evaluation of issuers, many of which also present EBITDA, Adjusted EBITDA and Adjusted Net Income (including diluted adjusted net income per share) when reporting their results in an effort to facilitate an understanding of their operating results.

These non-GAAP financial measures have limitations as analytical tools, and you should not consider these measures in isolation, or as a substitute for analysis of our results as reported under GAAP. Additionally, because not all companies use identical calculations, these presentations of EBITDA, Adjusted EBITDA and Adjusted Net Income (including diluted adjusted net income per share) may not be comparable to similarly titled measures of other companies.

EBITDA represents net (loss) income before interest, taxes, depreciation and amortization. Adjusted EBITDA and Adjusted Net Income (including diluted adjusted net income per share) represent EBITDA and net income (including diluted net income per share), respectively, adjusted to exclude management fees, stock-based compensation expense, loss on disposal of fixed assets, loss on modification or extinguishment of debt, foreign currency losses and gains, other (expense) income, equity in losses of unconsolidated joint ventures, transaction and acquisition related costs, relocation costs, severance costs and restructuring charges, non-cash rent adjustments and other one-time charges. Adjusted Net Income is also adjusted to exclude amortization of intangible assets and amortization of deferred financing costs. EBITDA and Adjusted EBITDA are not measurements of our financial performance under GAAP and should not be considered as alternatives to net (loss) income or other performance measures derived in accordance with GAAP or as alternatives to cash flow from operating activities as measures of our liquidity. EBITDA and Adjusted EBITDA have limitations as analytical tools, and you should not consider such measures either in isolation or as substitutes for analyzing our results as reported under GAAP. Some of these limitations are:

• EBITDA and Adjusted EBITDA do not reflect changes in, or cash requirements for, our working capital needs;
• EBITDA and Adjusted EBITDA do not reflect our interest expense, or the cash requirements necessary to service interest or principal payments, on our debt;
• EBITDA and Adjusted EBITDA do not reflect our tax expense or the cash requirements to pay our taxes;
• EBITDA and Adjusted EBITDA do not reflect historical capital expenditures or future requirements for capital expenditures or contractual commitments;
• although depreciation and amortization are non-cash charges, the assets being depreciated and amortized will often have to be replaced in the future, and EBITDA and Adjusted EBITDA do not reflect any cash requirements for such replacements; and
• other companies in our industry may calculate EBITDA and Adjusted EBITDA differently, limiting their usefulness as comparative measures.

Because of these limitations, EBITDA and Adjusted EBITDA should not be considered as discretionary cash available to us to reinvest in the growth of our business or as a measure of cash that will be available to us to meet our obligations.
