US Court Issues Preliminary Injunction Blocking Section 1260H List Enforcement, Wuxi AppTec Gains Positive Momentum

Overview

This is a quick note from Nomura regarding geopolitical developments for Wuxi AppTec (2359.HK). The core event is that the US Federal District Court approved a preliminary injunction filed by Wuxi AppTec, temporarily preventing the US Department of Defense from enforcing the Section 1260H list designation against the company. Nomura characterizes this development as positive and expects a favorable market reaction, maintaining its Buy rating and HKD 209.99 target price. The report is brief, falling under the category of event-driven quick notes.

Core views

This quick note focuses on a specific event. On August 9, 2026 (Hong Kong time), Wuxi AppTec announced that the US District Court for the District of Columbia had approved its motion for a preliminary injunction on August 7, 2026 (US time). This injunction temporarily prevents the US Department of Defense from enforcing the Section 1260H list designation against Wuxi AppTec during the course of the litigation. Nomura's assessment is: Although the preliminary injunction is merely a temporary measure, it represents a positive development for Wuxi AppTec. The core logic emphasized in the report is that the impact of Section 1260H list-related news on Wuxi AppTec is primarily sentimental rather than fundamental—the company recently reported very strong quarterly results and provided encouraging full-year guidance for FY2026. In other words, compared to actual operational performance, the news shock from the geopolitical list is more akin to a short-term emotional disturbance to valuation. Based on this positive direction, Nomura expects the market to react positively to the above developments. The firm maintains its Buy rating and target price of HKD 209.99 (derived using the DCF model). Regarding valuation, the report points out that the stock currently trades at approximately 20.5 times its fully diluted EPS of RMB 8.15 for FY2026.

Analysis framework

Nomura employs a typical 'Event - Nature Assessment - Maintain View' quick note framework. First, it confirms the event itself: the court issued a preliminary injunction during litigation, temporarily blocking the Department of Defense from enforcing the Section 1260H designation. It then assesses the nature of the event: it is a temporary measure but has a positive direction. The key deductive logic lies in distinguishing between 'sentimental impact' and 'fundamental impact': The report does not treat this geopolitical development as a catalyst for changing the company's fundamentals. Instead, it places this development in the broader context of the company's recently released strong quarterly results and positive FY2026 guidance, concluding that 'the news flow is sentiment-driven, while fundamentals remain unaffected.' For valuation, the DCF model is continued (assuming a WACC of 10.1% and a terminal growth rate of 3.5%), with the target price of HKD 209.99 based on the model's output, not adjusted due to this specific event.

Methodology notes

• Event Game Theory and Behavioral FinanceEvent-driven analysis

  Treating the preliminary injunction of the geopolitical list litigation as an event to judge its short-term direction and nature on the stock price

  The report revolves around the single-point event of the 'court's preliminary injunction,' judging it as positive but temporary. Event-driven analysis is commonly used in quick note reports, with the core being to judge the short-term directional impact of events on stock prices, rather than re-evaluating the company's long-term value.

• Valuation methodsDCF Discounted Cash Flow

  Target price of HKD 209.99 is based on the DCF model, assuming a WACC of 10.1% and a terminal growth rate of 3.5%

  DCF is a discounted cash flow valuation method that discounts future corporate cash flows back to their current value at a certain discount rate. The report uses a weighted average cost of capital of 10.1% and a perpetual growth rate of 3.5% to calculate the target price, using the Hang Seng Index as the benchmark index for the stock.

• Event Game Theory and Behavioral FinanceExpectation Gap / Expectation Management

  Distinguishing between the 'sentimental impact' and 'fundamental impact' of Section 1260H list news on stock prices

  The report's core judgment is that Section 1260H list news is more of a sentiment-level disturbance, while the company's recently reported strong performance and positive guidance are the fundamental anchors. This distinction between 'sentiment vs. fundamentals' reflects expectation management thinking, helping investors avoid misinterpreting short-term market sentiment as long-term operational deterioration.

Impact & implications

Nomura believes that the implementation of the preliminary injunction tilts geopolitical developments in favor of Wuxi AppTec, expecting a positive market reaction. However, the report simultaneously emphasizes that this is only a temporary measure, with litigation still ongoing, and the Section 1260H list designation has not been finally lifted. More importantly, the institution reaffirms that its judgment on Wuxi AppTec's fundamentals has not changed: the company just reported strong quarterly results and positive FY2026 guidance, so the substantive impact of geopolitical news on fundamentals is limited, being mostly fluctuations at the emotional level.

Risks

• The Section 1260H list litigation is ongoing, and the preliminary injunction is only a temporary measure. If subsequent rulings are unfavorable, geopolitical pressure may increase again.
• Increased competition or declining demand could lead to slowed growth.
• The target price is based on DCF model assumptions; if the company's earnings deviate from expectations, the target price may not be realized.

What to watch

• Subsequent developments and final judgment results of the Section 1260H list litigation.
• Whether the preliminary injunction will be extended or converted into a formal ruling.
• The actual realization of the company's subsequent performance and full-year FY2026 guidance.
