Trip.com Group Limited's stock experienced a 5.01% plunge intraday, reflecting heightened investor concern following significant corporate and regulatory developments.

The company announced that co-founders Fan Min and Ji Qi have resigned from their positions as director and president, and director, respectively. Such departures of key founding members often prompt market uncertainty regarding future leadership and strategic direction.

Concurrently, the company disclosed in its financial results that it received a notice in January 2026 that China's State Administration for Market Regulation (SAMR) has commenced an investigation pursuant to the PRC Anti-monopoly Law. The ongoing regulatory probe into potential monopolistic practices represents a material risk that has negatively impacted investor sentiment.
