Why Is WuXi AppTec successively selling its subsidiaries? The strategy behind a CXO giant's asset sales

On one hand, its Q3 2025 Report delivered the strongest performance to date: quarterly revenue surpassed the 120 billion yuan mark for the first time, reaching 12.057 billion yuan, a year-on-year increase of 15.26%. Net profit reached 5.13 billion yuan, surging 82.89% year-on-year, exceeding market expectations.

On the other hand, WuXi AppTec simultaneously disclosed the announcement of its asset sale, proposing to sell 100% equity in WuXi Clinical and MedKey for 2.8 billion yuan. It is worth noting that both targets are leading companies in China's CRO (Contract Research Organization) sector and are key entities under WuXi AppTec responsible for clinical research services.

Since the beginning of this year, WuXi AppTec has successively sold multiple overseas subsidiaries including Advanced Therapies and Oxford Genetics, as well as its US medical device testing business, indicating frequent asset adjustments.

Against the backdrop of a record-high quarterly performance on one side and the sale of subsidiaries on the other, what strategic logic is hidden behind WuXi AppTec's simultaneous expansion and reduction? Why are these subsidiaries being sold? How has its overall strategy evolved? 

The sale of subsidiaries may be a strategic move by WuXi AppTec to proactively optimize its business structure, or a necessary response to external environmental changes.

First, influenced by the U.S. Biosecurity Act, WuXi AppTec has swiftly adjusted its overseas asset portfolio. On January 25, 2024, both houses of the U.S. Congress introduced the Biosecurity Act targeting Chinese biotech companies such as BGI Group and WuXi AppTec, citing the protection of genetic data and national security. Following the news, WuXi AppTec and BGI became the focus of market attention, with their stocks hitting consecutive daily limit downs. By February 19, WuXi AppTec's A-share and Hong Kong stock prices had fallen by 31% and 46%, respectively, wiping out nearly 100 billion yuan in market value.

Despite issuing more than ten statements asserting that its operations pose no risk to U.S. national security, WuXi AppTec was unable to curb the U.S. practice of suppressing it under pretexts. The U.S. House of Representatives passed the Biosecurity Act on September 9, 2024, which was subsequently shelved due to an incomplete legislative process. Later that month, senators introduced Amendment S.3558 to the Senate. This amendment not only upheld the ban on U.S. firms contracting with designated biotech suppliers but also incorporated extensive new provisions concerning genetic services.

Against this backdrop, WuXi AppTec sold its U.S. entity Advanced Therapies and U.K. entity Oxford Genetics—which operated its WuXi ATU (WuXi AppTec's cell and gene therapy division) business—to the American private equity firm Altaris for a cash consideration at the end of December 2024.

Regarding WuXi AppTec's divestiture of its WuXi ATU business, CLSA had disclosed the company's divestment intention prior to the official announcement, noting the decision was driven by the business's high sensitivity to the U.S. Biosecurity Act and its below-expectation growth rate in recent years.

This may indeed represent a compelled choice. From a market perspective, WuXi AppTec's WuXi ATU business holds a significant position in the global cell and gene therapy (CGT) sector, having secured the commercial production order for the world's first TIL therapy, AMTAGVI, in February 2024. From January to November 2024, the two divested entities generated approximately 980 million yuan in combined revenue (unaudited). While this accounted for merely 2.4% of WuXi AppTec's total audited revenue from the last fiscal year—indicating minimal impact on its overall financial health—the segment's prospects cannot be overlooked. The CGT field continues to witness emerging therapies like TIL, TCR-T, and CAR-NK, which are poised for rapid expansion. Unfortunately, the U.S. Biosecurity Act has substantially heightened operational risks for WuXi AppTec in conducting such businesses within the United States.

An industry insider stated: "WuXi AppTec has repeatedly issued announcements emphasizing that its operations do not involve data collection and it has no human genomics business, yet the U.S. side remained unresponsive. Divesting the cell and gene therapy business could alleviate U.S. concerns regarding the security of WuXi AppTec's operations and reduce the policy risks and uncertainties it faces in the American market."

Under these circumstances, although the U.S. Senate passed the FY2026 National Defense Authorization Act, which incorporated a new version of the Biosecurity Act, with a majority vote on October 9, 2025, WuXi AppTec had already achieved a soft landing by selling its U.S. and U.K. entities operating the WuXi ATU business. From January to September 2025, the company's revenue derived from U.S. clients reached 22.15 billion yuan, reflecting a year-on-year increase of 31.9%.

Second, proactively optimizing its global business portfolio by divesting non-core assets to strengthen its integrated CRDMO model. In January 2025, WuXi AppTec announced the sale of its manufacturing facilities in Atlanta, Georgia and St. Paul, Minnesota to NAMSA, a leading medical device CRO service provider.

Previously, WuXi AppTec's U.S. medical device operations were primarily conducted through its wholly-owned subsidiary AppTec, which maintained laboratories in Philadelphia, St. Paul, and Atlanta providing medical device testing services and overseas precision medicine R&D production. The company also offered comprehensive testing services through its cGMP and GLP R&D and manufacturing base in Minnesota.

This transaction enables NAMSA to expand its service capabilities, providing clients with integrated clinical research and testing solutions. For WuXi AppTec, the divestiture generates proceeds while successfully streamlining its strategic business portfolio, allowing the company to focus on further investments in core CRDMO operations both in the United States and other regions, thereby strengthening its unique CRDMO model in the pharmaceutical sector.

The CRDMO business model refers to WuXi AppTec's integrated platform that provides end-to-end services for novel drugs, spanning from early-stage discovery and research (R) through development (D) to manufacturing (M). Its core strength lies in robust capabilities in client engagement, market insight, and internal synergy, enabling innovative drug molecules to flow seamlessly across WuXi AppTec's various business divisions, thereby forming a formidable competitive barrier. For instance, WuXi AppTec's small molecule drug discovery (R) business successfully delivered over 460,000 new compounds in 2024. Leveraging this vast repository of small molecules, the company advanced 366 molecules from research (R) to development (D) in 2024, with the related pipeline continuing to expand. Through its comprehensive one-stop service model, WuXi AppTec is progressively moving more molecules from the R stage to the D and M stages, driving sustained growth in commercial orders.

On October 26, WuXi AppTec announced the sale of its subsidiaries WuXi Clinical and MedKey to Hillhouse Capital for 2.8 billion yuan, a strategic move to further concentrate on its CRDMO business model. This divestment allows the company to reallocate more resources to core segments, such as drug discovery, laboratory testing, process development, and manufacturing services, thereby enhancing its competitiveness in these key areas.

Both divested entities belonged to the clinical development services segment of WuXi AppTec's CRO business. WuXi Clinical specializes in comprehensive clinical research services for innovative drugs, covering Phases I-IV clinical trials and real-world studies. MedKey is a leading SMO (Site Management Organization) in China with a team of over 5,300 professionals.

From January to September 2025, WuXi Clinical and MedKey collectively generated approximately 1.16 billion yuan in unaudited revenue, accounting for about 3.5% of WuXi AppTec's total unaudited revenue during the same period. Their combined unaudited net profit reached around 90 million yuan, representing 0.7% of the company's total.

The total transaction value of 2.8 billion yuan significantly exceeds the target companies' current net asset value (their total assets amounted to approximately 1.82 billion yuan at the end of 2024). This disposal will generate profit contributions for WuXi AppTec and strengthen its cash flow position. The company stated: "This divestment aligns with our strategy to focus on the CRDMO business model and concentrate on drug discovery, laboratory testing, and process development and manufacturing services. The proceeds will help accelerate the deployment of our global capabilities and production capacity, supporting our corporate development strategy and long-term interests."

Third, capitalizing on market momentum by divesting shares in WuXi XDC to realize investment returns. Between November 2024 and October 2025, WuXi AppTec executed four consecutive share reductions in WuXi XDC, cumulatively realizing approximately HK$6.95 billion in proceeds.

The company stated in its disclosure that the capital generated from these divestments would be allocated to accelerating global capacity and capability expansion, attracting and retaining top talent, and further strengthening its unique integrated CRDMO business model—thereby more effectively meeting the evolving demands of global clients and patients.

While this explanation presents a logical narrative of "reallocating divestment proceeds to reinforce business development and model enhancement," the crucial point remains that WuXi AppTec already maintains ample liquidity, negating the necessity of raising funds through equity sales to drive operational upgrades. According to its financial reports, the company’s cash and cash equivalents stood at approximately 13.445 billion yuan at the end of 2024, increased to 17.552 billion yuan by June 2025, and further grew to 25.476 billion yuan as of September 2025.

Especially since WuXi XDC holds the position as the world's second-largest and China's largest player in the R&D and production services (CRDMO) for bioconjugate drugs such as Antibody-Drug Conjugates (ADCs), representing significant long-term investment value. This long-term confidence in its business prospects is further underscored by the recent move from another WuXi ecosystem company, WuXi Biologics, which increased its stake in WuXi XDC with an investment of HK$1.311 billion.

This suggests that there are underlying implications behind WuXi AppTec's divestment of WuXi XDC shares. The period from November 2024 to October 2025 coincided with a sustained upward trend in WuXi XDC's stock price, which rose from HK$30 to HK$85.5. It is plausible that WuXi AppTec's divestment was strategically timed to capitalize on this price appreciation, converting paper gains into realized cash profits and thereby building a "war chest" for future investments in its core businesses.

The divestment of WuXi XDC shares has had a notable impact on WuXi AppTec's income statement. According to financial reports, WuXi AppTec's net profits for 2023, 2024, and the first half of 2025 were 9.7 billion yuan, 9.568 billion yuan, and 8.66 billion yuan, respectively. During these periods, the company's investment income amounted to 234 million yuan, 604 million yuan, and 3.669 billion yuan, representing 2.41%, 6.31%, and 42.37% of its total pre-tax profits. In 2025 alone, the net investment gains from selling WuXi XDC shares contributed 4.351 billion yuan to WuXi AppTec's after-tax net profit, accounting for 36% of its net profit in the first three quarters.

In summary, WuXi AppTec's successive divestments from the long-term valuable WuXi XDC and the sale of its two subsidiaries have significantly boosted its cash reserves. This strategic move may signal other important initiatives in the pipeline, warranting continued attention.

WuXi AppTec's strategic priorities can be discerned from its latest financial report.

On October 26, the company's earnings report revealed third-quarter revenue of 12.057 billion yuan, representing a 15.26% year-on-year increase, with net profit attributable to shareholders reaching 3.515 billion yuan, up 53.27% year-on-year. For the first three quarters, WuXi AppTec achieved total revenue of 32.857 billion yuan, an 18.61% year-on-year growth, while net profit attributable to shareholders surged 84.84% to 12.076 billion yuan.

By business segment, chemical business revenue reached 25.98 billion yuan in the first three quarters, rising 29.3% year-on-year; testing business revenue recorded 4.17 billion yuan, edging down 0.04% year-on-year; and biology business revenue grew 6.6% to 1.95 billion yuan.

As of the end of September 2025, WuXi AppTec's order backlog for continuing operations stood at 59.88 billion yuan, reflecting a substantial 41.2% year-on-year increase.

The significant order growth has been largely driven by the integrated CRDMO business model.

Dr. Minzhang Chen, Co-CEO of WuXi AppTec, stated: "Under the CRDMO model, the small molecule pipeline within our chemical business platform continues to expand both in volume and quality. Projects flow steadily through the R-D-M funnel, transitioning seamlessly from one stage to the next. From the second half of 2024 to the first half of 2025, the small molecule business delivered over 440,000 compounds at the Research stage; maintained 3,333 molecules in the Development stage, a 3% year-on-year increase; and had 76 molecules in the commercial Manufacturing stage, up 13% year-on-year."

Compared to 2018, WuXi AppTec has now achieved a 17-fold increase in D&M stage orders from a base of R-stage orders that only doubled. This demonstrates the predictable growth trajectory enabled by the R-stage project inflow within the CRDMO model.

It is worth noting that within its chemical business, WuXi AppTec's strategic focus on new molecular modalities such as peptides and oligonucleotides has become a major growth driver. In the first three quarters of 2025, revenue from its TIDES business (comprising oligonucleotides and peptides) reached 7.84 billion yuan, surging 121.1% year-on-year. The segment's order backlog also grew by 17.1%, while the number of clients using TIDES D&M services increased by 12%, and the number of molecules serviced rose by 34%.

Likely recognizing the strong competitiveness of its unique CRDMO model, WuXi AppTec has repeatedly emphasized its intention to use the proceeds from share divestments to attract and retain top talent, thereby continuously strengthening its integrated CRDMO business model.

Another key driver behind the substantial order growth is the capacity expansion in its Development and Manufacturing (D&M) segment. Data released by WuXi AppTec shows that the proportion of capital expenditure allocated to D&M capacity has increased from 28% in 2018 to approximately 85% in 2025. This significant investment in production capacity has enhanced the company's ability to secure high-quality molecules. With the rising proportion of late-stage and commercial projects, along with the growing share of new molecular modalities, WuXi AppTec has maintained rapid growth in both revenue and profit.

Building on this successful experience, WuXi AppTec has chosen to further accelerate capacity investment and expedite production base construction. In March 2025, both its Changzhou and Taixing API production bases successfully passed FDA on-site inspections with zero observations, and the total reactor volume for small molecule APIs is expected to exceed 4,000 kL by the end of 2025. In September 2025, the company completed its Taixing peptide capacity expansion ahead of schedule, increasing its total solid-phase peptide synthesis reactor volume to over 100,000 L.

Geographically, approximately 85% of WuXi AppTec's revenue in the first three quarters of 2025 came from overseas markets. Revenue from U.S. clients reached 22.15 billion yuan, accounting for about 68.26% of total revenue. In terms of growth rates, revenue from U.S. clients increased by 31.9% year-on-year, while European clients contributed 13.5% growth, and domestic Chinese client revenue grew only 0.5%. This indicates that overseas markets, particularly the U.S., remain WuXi AppTec's primary battlefield, necessitating a continued commitment to global expansion and enhanced worldwide capabilities.

Consequently, WuXi AppTec plans to accelerate facility development across Asia, Europe, and America to build a comprehensive global supply chain network.

In the United States, WuXi AppTec announced the opening of its Boston Center of Excellence in Watertown, Massachusetts on September 10, 2025. The company is also advancing the construction of its Middleton site, scheduled to commence operations by the end of 2026, while steadily progressing with its Delaware production base, expected to become operational in the fourth quarter of 2026.

In Asia, WuXi AppTec's Singapore R&D and manufacturing base commenced construction in 2024, with its first phase planned to launch in 2027.

In Europe, the company is continuously expanding its Couvre manufacturing facility in Switzerland. The packaging capacity for oral dosage forms was doubled in 2024, and a spray drying workshop is under construction, set for completion in the fourth quarter of 2026. Additional capabilities in parenteral formulations will be added subsequently.

To date, WuXi AppTec's chemical business platform operates 15 facilities globally, spanning China, the U.S., Switzerland, and Singapore. With its ongoing capacity investments, the company is positioned to provide clients with a flexible and resilient global supply network, further mitigating risks associated with geopolitical factors.
