Management Comment

“WuXi continues to make progress in building a broad, integrated platform of R&D services that will enable anyone and any company to discover and develop medicines more efficiently and cost effectively,” said Dr. Ge Li, Chairman and Chief Executive Officer. “This integrated platform does more than simply provide convenience to clients; it helps them realize their dream of being a drug discoverer and developer.

“By serving our customers well, we are achieving solid, broad-based revenue growth,” Dr. Li continued. “We exceeded our second-quarter 2013 revenue guidance, driven by excellent performances by China-based Laboratory Services and Manufacturing Services. We also exceeded our second-quarter 2013 EPS guidance. Year-over-year GAAP diluted EPS growth of 45.5% benefited from this revenue performance, gross margin improvement, large mark-to-market gains from foreign-exchange forward contracts, and lower tax expense.

“We are also building businesses to sustain growth in 2014 and beyond. Revenues from biologics services grew strongly in the second quarter and will be one of the key drivers of revenue and earnings growth for the next several years. Commercial manufacturing has a growing pipeline of products, several of which have received breakthrough designation by the U.S. FDA. And our joint venture WuXiPRA has named an experienced executive, Dr. James Pusey, as President and General Manager to lead it to the forefront of China’s clinical research services business.

“WuXi is also effectively controlling its costs through continuous operational improvements, increased productivity, and implementation of a company-wide Lean Sigma program. We continue to expect to achieve gross margin and operating margin in 2013 comparable to 2012, as businesses like small-molecule drug development and biologics services ramp up their revenues, achieve scale, and provide solid returns on investment.

“Our strong second-quarter performance gives us confidence to increase full-year 2013 revenue guidance to $572-$578 million and full-year 2013 diluted EPS guidance to $1.38-$1.44 GAAP and $1.61-$1.67 non-GAAP,” Dr. Li concluded. “We are investing in capabilities and capacity to sustain long-term revenue and earnings growth. Capital expenditures will increase in the second half of the year as planned and total about $60 million for the full year. Our free cash flow has been quite strong in recent quarters, and we will continue to seek opportunities to buy back shares.”

Second-Quarter 2013 GAAP Results

Second-quarter 2013 net revenues increased 9.2% year over year to $142.3 million. Revenue growth in Laboratory Services of 13.2% was driven by our comprehensive and integrated discovery and development services, primarily in China. A revenue decline of 1.1% in Manufacturing Services was caused by slightly lower demand compared to the record level achieved in the second quarter of 2012.

Second-quarter 2013 GAAP gross profit increased 11.3% year over year to $51.8 million due to 9.2% revenue growth, improved operating efficiency, and effective cost control. Gross margin increased year over year to 36.4% from 35.7%. Gross margin in Laboratory Services increased year over year to 38.9% from 36.7% mainly due to improved productivity and the ramp-up of biologics and preclinical services, partially offset by the effects of increasing labor costs in China and appreciation of the RMB versus the U.S. dollar. Gross margin in Manufacturing Services decreased year over year to 29.1% from 33.1% due to business mix.

Second-quarter 2013 GAAP operating income increased 8.1% year over year to $25.7 million due to the 11.3% increase in gross profit, partially offset by a 14.7% increase in operating expenses. Operating margin declined slightly to 18.1% from 18.2%, primarily due to the increase in operating expenses.

Second-quarter 2013 GAAP net income increased 44.6% year over year to $29.6 million due to the 8.1% year-over-year increase in operating income, higher other income primarily due to $1.6 million of realized gains and $3.0 million of mark-to-market gains on foreign-exchange forward contracts, and a 6.2% decrease in income tax expense due to the mix of taxable income and $2.3 million of one-time tax benefits received this quarter, partially offset by $1.4 million of equity-method investment losses associated with our joint ventures with PRA and MedImmune.

Second-quarter 2013 GAAP diluted earnings per ADS increased 45.5% to $0.41 due to the 44.6% increase in net income and a lower number of outstanding ADSs as a result of last year’s share buybacks. Second-quarter 2013 GAAP comprehensive income increased 102.6% year over year to $37.4 million due to the increase in currency translation adjustments and the 44.6% increase in GAAP net income.

Second-Quarter 2013 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 2013 non-GAAP gross profit increased 10.2% year over year to $53.0 million, due to the revenue growth, improved operating efficiency, and effective cost control discussed above. Non-GAAP gross margin increased year-over-year to 37.2% from 36.8%, mainly due to improved productivity and the ramp-up of biologics and preclinical services, partially offset by the effects of increasing labor costs in China and appreciation of the RMB versus the U.S. dollar.

Second-quarter 2013 non-GAAP operating income increased 8.8% year over year to $29.8 million, primarily due to the 10.2% increase in non-GAAP gross profit. Operating margin declined slightly to 20.9% from 21.0%, primarily due to higher operating expenses.

Second-quarter 2013 non-GAAP net income grew 41.0% year over year to $33.7 million due to the 8.8% increase in non-GAAP operating income, higher other income primarily due to $1.6 million of realized gains and $3.0 million of mark-to-market gains on foreign-exchange forward contracts, and a decrease in income tax expense due to the mix of taxable income and $2.3 million of one-time tax benefits received this quarter, partially offset by $1.4 million of equity-method investment losses associated with our joint ventures with PRA and MedImmune.

Second-quarter 2013 non-GAAP diluted earnings per ADS grew 41.9% year over year to $0.46 due to the 41.0% increase in net income and a lower number of outstanding ADSs as a result of last year’s share buybacks.

Examples of forward-looking statements in this press release include statements about our third-quarter and full-year 2013 guidance and our goal of building an open-access technology platform. 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, and to compete effectively. 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, 2012.

Use of Non-GAAP and Pro-Forma Financial Measures

We have provided the second-quarter and first-half 2012 and 2013 gross profit, gross margin, operating income, operating margin, net income, net margin, and 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. We believe both 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. These non-GAAP operating measures are useful for understanding and assessing underlying business performance and operating trends. We expect to continue to provide net income and earnings per ADS on a non-GAAP basis using a consistent method on a quarterly basis. 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, and you should refer to the reconciliation of GAAP measures to non-GAAP measures for the indicated periods in this press release.
