Shanghai Fudan's stock fell sharply during intraday trading, plummeting 5.42%. The decline followed the release of the company's first-quarter financial results, which revealed a concerning divergence between top-line and bottom-line growth.

The company reported operating revenue of approximately RMB 1.032 billion for Q1 2026, representing a year-on-year increase of 16.23%. However, net profit attributable to shareholders grew only 8.91% to RMB 148 million. This significant mismatch was primarily driven by a substantial year-over-year increase in R&D expenses of approximately RMB 63 million, which compressed margins and disappointed investors.

Analysts note that the market has been particularly sensitive to profitability shortfalls for Shanghai Fudan, given the company's elevated valuation and historical earnings volatility. The surge in R&D spending, while potentially beneficial for long-term growth, weighed heavily on near-term profit margins and triggered the selling pressure observed during the session.
