Management Comments

“We delivered yet another strong performance for the first half of 2017, with revenues across each of our key geographies increasing significantly,” said Dr. Ge Li, Chairman of WuXi Biologics. “With US$452 million of backlog and 134 ongoing integrated projects, the momentum of our business is stronger than ever. We continue to be confident that we will deliver 2017 full-year financials as we expected.”

“The growth of the global biologics market showed no signs of abating in the first half of 2017 and WuXi Biologics has certainly been a key beneficiary,” said Dr. Chris Chen, CEO of WuXi Biologics. “Our established track record and reputation as an open-access and integrated biologics platform continue to attract new customers and more projects from existing customers, which became evident in the financial results for the first half of 2017. Our revenue and adjusted EBITDA grow 59.5% and 51.7% year-on-year respectively, which is a strong manifestation of impressive execution of our “follow-the-molecule” strategy. Overall, gross profit margin, adjusted EBITDA margin and adjusted net profit margin of the last 6 months all compare favorably to those of full-year 2016.”

“In terms of our expansion plans, the construction of our Wuxi and Shanghai facilities is fully on track, with the facilities scheduled to become operational in Q4 2017 and Q2 2018 respectively. We also continue to be able to attract top-notch talents, which is a key business focus and competitive strength of ours. We grew our employee headcount from 1,624 at the end of 2016 to 1,998 as of June 30, 2017.”

“We have witnessed phenomenal backlog growth in recent months due to our increasingly solid track record in the global competitive landscape, our successful execution of business development in Europe, and doubling of our late phase projects from 3 to 6 requiring more process development and large-scale manufacturing.”

“We have also achieved key business milestones in recent months. In early August this year, the US FDA completed the pre-license inspection (PLI) of our current cGMP manufacturing facilities for production of ibalizumab with no critical observations. If approved, ibalizumab will be the first biologics drug approved in the United States to be commercially manufactured in China. This validates both our global quality standard and pioneer use of single-use systems for commercial manufacturing. Separately, in a recent deal with a total value of up to US$816 million, we and our partner Harbin Gloria Pharmaceuticals (“Gloria”) granted Arcus Biosciences an exclusive license of GLS-010, a novel anti-PD-1 antibody for several markets outside of China. We and Gloria expect to receive US$18.5 million upfront payment during the second half of 2017 of which approximately US$1.55 million will be paid to Gloria. This important development demonstrates that our China gateway and global capabilities allow us to increase our potential revenues significantly for each molecule. We are highly confident that we will continue to execute our strategy well and deliver as expected financial results full year 2017,” Dr. Chen added.

1H 2017 Interim Results

Revenue increased by 59.5% year-on-year to RMB654.0 million in the first half of 2017. The major revenue growth drivers are (i) a continued increase in the number of customers and the strong growth in the number of integrated projects; (ii) marketing efforts by the Group, resulting in robust performance in China, United States and Europe.

Gross profit grew 41.6% year-on-year to RMB264.3 million while gross profit margin was 40.4%, compared to 45.5% and 39.3% for the first six months and full year of 2016 respectively. The lower gross profit margin compared to the first six months of 2016 was primarily due to higher milestone fees received during the first six months of 2016.

Adjusted EBITDA increased by 51.7% year-on-year to RMB266.1 million in the first half of 2017. Adjusted EBITDA margin was 40.7%, compared to 42.8% and 37.5% for the first six months and full year of 2016 respectively. The lower adjusted EBITDA margin compared to the first six months of 2016 was primarily due to higher milestone fees received during the first six months of 2016.

Net profit increased by 9.9% year-on-year to RMB92.2 million in the first half of 2017. Net profit margin was 14.1%, compared to 20.5% and 14.3% for the first six months and full year of 2016 respectively. The lower net profit margin compared to the first six months of 2016 was primarily due to (i) a higher interest expense[4]; (ii) impact of FX[5] losses, and (iii) higher milestone fees received during the first six months of 2016.

[4] The onshore bank loan of RMB 1 billion was fully repaid in July 2017 and the offshore loan of US$38.6 million is expected to be fully repaid in early September 2017. As such, interest expense is expected to decrease accordingly.

[5] FX represents the foreign currency exchange rate (US dollar VS RMB)

Adjusted net profit, which excludes share-based compensation, FX gains or losses, and listing expenses increased 35.8% year-on-year to RMB152.8 million in the first half of 2017. Adjusted net profit margin was 23.4%, compared to 27.4% and 22.2% for the first six months and full year of 2016 respectively. The lower adjusted net profit margin compared to the first six months of 2016 was primarily due to (i) higher interest expense and (ii) higher milestone fees received during the first six months of 2016.

Basic and diluted EPS remained unchanged year-on-year at RMB0.09.

Adjusted diluted EPS grew 25.0% from RMB 0.12 year-on-year to RMB 0.15.
