Company Reconfirms Full-Year 2015 Revenue Guidance of $790-$800 Million, Withdraws Full-Year 2015 Diluted EPS Guidance Due to Uncertainties Regarding Currency Exchange-Rate Volatility and Costs Associated with Several Transactions Under Consideration

Management Comment

“WuXi had excellent year-over-year revenue growth of 18.8% in the second quarter, meeting the company’s expectations,” said Dr. Ge Li, Chairman and CEO. “That revenue growth was again broad-based, with double-digit growth from each of the four segments of the business. Revenue growth in our small-molecule manufacturing businesses was slightly lower than expected due to the timing of product deliveries, but this is not expected to impact the full-year performance of this business. The revenue performance of our biologics business exceeded expectations. This overall performance gives us confidence to reconfirm our full-year 2015 revenue guidance of $790-$800 million.

“The quarter was also characterized by significant year-over-year declines in margins and diluted EPS because of sharply increased levels of investment in new businesses,” Dr. Li continued. “WuXi today is two groups of businesses—strong core businesses, and promising, but very challenging, new businesses. Our core businesses are performing well, generating solid revenue and operating income growth. But we also see many compelling investment opportunities in new businesses, such as in genomics / bioinformatics, e-commerce, and China healthcare initiatives, opportunities that we are choosing to seize during this period of strength to drive longterm growth. To date, these new businesses are developing more slowly than we had anticipated.

“As many of you know, the RMB depreciated significantly versus the US dollar earlier this week, and this depreciation could result in significant mark-to-market losses and realized losses on foreign-exchange forward contracts in the third quarter and full year,” Dr. Li concluded. “In addition, WuXi is considering several transactions that in comparison to historical results could further reduce margins and diluted EPS in full-year 2015 and beyond. Therefore, because of uncertainties regarding these circumstances, we are withdrawing our GAAP and non-GAAP diluted EPS financial guidance for full-year 2015.”

Second-Quarter 2015 GAAP Results

Second-quarter 2015 net revenues increased 18.8% year over year to $194.1 million. Laboratory Services revenue grew 17.9%, driven by our comprehensive and integrated drug discovery and development services. Revenue growth of 10.0% in Small-Molecule Manufacturing Services resulted from strong demand in both research manufacturing and commercial manufacturing, slightly reduced by the timing of deliveries of specific projects. Biologics Services revenue increased 48.4% from strong growth in both development and manufacturing. Revenue growth of 42.8% in New Businesses and Other related mainly to the significant revenue increase of clinical site management services in China, offset by slower than expected growth in the genomics / bioinformatics business.

Second-quarter 2015 GAAP gross profit increased 8.4% year over year to $66.7 million due to 18.8% revenue growth, partially offset by increased labor costs in China and investments in new businesses. Gross margin decreased year over year to 34.4% from 37.7%. Gross margin in Laboratory Services decreased year over year to 37.0% from 40.9% due to increased labor costs in China and investments in new businesses. Gross margin in Small-Molecule Manufacturing Services increased year over year to 36.6% from 31.8% because of changes in business mix and higher capacity utilization. The decrease in gross margin in Biologics Services year over year to 25.0% from 34.5% was caused by investments in biomanufacturing, which is in an early stage of its revenue ramp-up. Gross margin in New Businesses and Other decreased year over year to (5.8%) from 25.3% mainly as a result of investments in genomics and bioinformatics.

Second-quarter 2015 GAAP operating income decreased 39.1% year over year to $17.1 million mainly due to investments in new businesses, including increased selling and marketing, general and administrative, and research and development expenses and transaction expenses related to the proposed privatization, partially offset by the 8.4% increase in gross profit. Operating margin declined to 8.8% from 17.1% due to these increased operating expenses.

Second-quarter 2015 GAAP net income decreased 33.7% year over year to $19.4 million mainly due to the 39.1% year-over-year decrease in operating income, an adverse change in realized gains on settled foreign-exchange forward contracts (gains of $0.2 million in the second quarter of 2015 compared to gains of $1.6 million in the second quarter of 2014), larger equity-method investment losses from our joint ventures with PRA and MedImmune and other equity-method investments, losses of $1.2 million from writing off an investment in a portfolio company by our venture fund and lower gains on the sale of investments by the corporate venture fund (gains of $1.1 million in the second quarter of 2015 compared to gains of $2.2 million in the second quarter of 2014), and higher interest expense due to higher loan balances needed to support increased investment, partially offset by a favorable change of $5.8 million in mark-to-market gains and losses on foreign-exchange forward contracts (gains of $3.3 million in the second quarter of 2015 compared to losses of $2.5 million in the second quarter of 2014).

Second-quarter 2015 GAAP net income attributable to WuXi shareholders decreased 35.7% year over year to $18.9 million mainly due to the 33.7% year-over-year decrease in net income and net income attributable to non-controlling interests of $0.6 million in 2015.

Second-quarter 2015 GAAP diluted earnings per ADS attributable to WuXi shareholders decreased 35.9% year over year to $0.26 due to the 35.7% decrease in net income attributable to WuXi shareholders and a higher number of outstanding ADSs as a result of share issuances relating to the XenoBiotic Laboratories acquisition and vesting of restricted stock units, partially offset by the impact of share purchases in 2014. Second-quarter 2015 GAAP comprehensive income attributable to WuXi shareholders decreased 21.2% year over year to $19.0 million mainly due to the 35.7% decrease in net income and an unfavorable change in unrealized losses on available-for-sale securities, partially offset by favorable changes in currency translation adjustments and cash flow hedges.

Second-Quarter 2015 Non-GAAP Results

Non-GAAP financial results exclude the impact of share-based compensation expenses and the amortization of acquired intangible assets and the associated deferred tax impact.

Second-quarter 2015 non-GAAP gross profit increased 11.6% year over year to $70.5 million due to 18.8% revenue growth, offset by increased labor costs in China and investments in new businesses. Non-GAAP gross margin decreased year over year to 36.3% from 38.7% for the same reasons.

Second-quarter 2015 non-GAAP operating income decreased 22.3% year over year to $26.4 million due to investments in new businesses, including increased selling and marketing, general and administrative, and research and development expenses and transaction expenses related to the proposed privatization, partially offset by the 11.6% increase in non-GAAP gross profit. Non-GAAP operating margin decreased to 13.6% from 20.8% due to higher operating expenses.

Second-quarter 2015 non-GAAP net income decreased 19.4% year over year to $28.4 million mainly due to the 22.3% year-over-year decrease in operating income, an adverse change in realized gains on settled foreign-exchange forward contracts (gains of $0.2 million in the second quarter of 2015 compared to gains of $1.6 million in the second quarter of 2014), larger equity-method investment losses from our joint ventures with PRA and MedImmune and other equity-method investments, losses of $1.2 million from writing off an investment in a portfolio company by our venture fund and lower gains on the sale of investments by the corporate venture fund (gains of $1.1 million in the second quarter of 2015 compared to gains of $2.2 million in the second quarter of 2014), and higher interest expense due to higher loan balances needed to support higher investment, partially offset by a favorable change of $5.8 million in mark-to-market gains and losses on foreign-exchange forward contracts (gains of $3.3 million in the second quarter of 2015 compared to losses of $2.5 million in the second quarter of 2014).

Second-quarter 2015 non-GAAP net income attributable to WuXi shareholders decreased 21.3% year over year to $27.7 million mainly due to the 19.4% year-over-year decrease in net income and net income attributable to noncontrolling interests of $0.6 million in 2015.

Second-quarter 2015 non-GAAP diluted earnings per ADS attributable to WuXi shareholders decreased 21.6% year over year to $0.38 due to the 21.3% decrease in net income attributable to WuXi shareholders and a higher number of outstanding ADSs as a result of share issuances relating to the XenoBiotic Laboratories acquisition and vesting of restricted stock units, partially offset by the impact of share purchases in 2014.

Full-Year 2015 Financial Guidance

WuXi PharmaTech reconfirms full-year 2015 revenue guidance of $790-$800 million. The company withdraws its full-year 2015 guidance for GAAP and non-GAAP diluted EPS because of uncertainties regarding currency exchange-rate volatility and potential significant costs associated with several transactions under consideration. The rapid depreciation of the RMB against the U.S. dollar could result in significant mark-to-market losses and realized losses on foreign-exchange forward contracts.

Forward-Looking Statements

This press release contains “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements are not historical facts, but instead are predictions about future events. Examples of forward-looking statements in this press release include statements about expected full-year 2015 revenues, costs associated with several transactions under consideration and the related negative impact on gross margins and earnings per share (EPS), expected drivers of our future growth, and our planned investments in small-molecule manufacturing, biologics, new businesses and other areas and expected market opportunities and trends and related benefits of those investments. Although we believe that our predictions are reasonable, future events are inherently uncertain, and our forward-looking statements may turn out to be incorrect. Our forward-looking statements are subject to risks relating to, among other things, our ability to control our costs and sustain revenue growth, to realize the anticipated benefits of our investments, to protect our clients’ intellectual property, to compete effectively, and to complete the expansion of our small-molecule manufacturing facilities in Changzhou and other manufacturing facilities and potential co-development and acquisition activities. Additional information about these and other relevant risks can be found in our Annual Report on Form 20-F for the year ended December 31, 2014. The forward-looking statements in this press release speak only as of the date on which they are made, and we assume no obligation to update any forward-looking statements except as required by law.

Use of Non-GAAP Financial Measures

We have provided the second-quarter 2014 and 2015 gross profit, gross margin, operating income, operating margin, net income, net margin, and diluted earnings per ADS on a non-GAAP basis, which excludes share-based compensation expenses and the amortization and deferred tax impact of acquired intangible assets. The non-GAAP financial measures used in this press release are useful for understanding and assessing underlying business performance and operating trends, and we believe that management and investors benefit from referring to these non-GAAP financial measures in assessing our financial performance and liquidity and when planning and forecasting future periods. We expect to continue to provide such non-GAAP financial measures on a quarterly basis using a consistent method. You should not view non-GAAP results on a stand-alone basis or as a substitute for results under GAAP, or as being comparable to results reported or forecasted by other companies.

Statement Regarding Unaudited Financial Information

The financial information in this press release is unaudited and subject to adjustments. Adjustments to the financial statements may be identified when our annual financial statements are prepared and audit work is performed for the year-end audit, which could result in significant differences from this unaudited financial information.
