Trip.com Group, China's largest online travel agency, has flagged its slowest revenue growth in over three years and warned investors of a potentially “significant fine” stemming from an antitrust investigation by the country’s top market regulator. The dual blow — a decelerating top line and regulatory overhang — rattled confidence in the Nasdaq-listed company following its Thursday, 25 June 2026 earnings release.

Q1 results and a cautious Q2 outlook

Trip.com posted first-quarter 2026 revenue of 16.2 billion yuan (approximately US$2.4 billion), a 17 per cent year-on-year increase. However, net profit for the March quarter tumbled nearly 42 per cent to 2.5 billion yuan, the weakest quarterly profit since late 2024.

For the second quarter, the company guided revenue growth of just 3 to 8 per cent — the softest forecast since late 2022, a period when China’s travel sector was still constrained by pandemic-era restrictions. The sharp deceleration signals that post-pandemic revenge-travel tailwinds are fading faster than anticipated.

Why it matters: Airfare pressure and booking shifts

Chief Financial Officer Cindy Wang attributed the slowdown to a confluence of macroeconomic headwinds. “Rising energy prices and recent geopolitical tensions have led to higher airfares, tighter airline capacity, and disruptions on certain international routes, particularly long-haul travel, contributing to a moderation in air travel demand and changes in booking patterns,” she said on the earnings call.

The company, which operates the Ctrip and Qunar platforms domestically as well as the global metasearch engine Skyscanner, is particularly exposed to long-haul international routes where capacity constraints are most acute. Its train-ticketing business provides a partial domestic buffer, but cannot fully offset weakness in higher-margin air travel bookings.

The regulatory backdrop: Antitrust probe looms large

The State Administration for Market Regulation (SAMR) announced an antitrust investigation into Trip.com in January 2026. The company disclosed on Thursday that the probe “could directly result in a significant fine, other financial penalties [or] changes to the company’s business practices”, which “may have a material adverse effect on the company’s consolidated financial position, results of operations, or cash flows.”

Trip.com added it could not “predict the timing, outcome or consequences of the investigation, or estimate the possible loss.” The open-ended disclosure offers investors little visibility, a dynamic that typically weighs on valuation multiples until a resolution is reached.

Competitive context

China’s online travel sector has grown intensely competitive, with domestic rivals and global platforms vying for the same pool of outbound and inbound travellers. Regulatory scrutiny of dominant platforms — spanning the State Administration for Market Regulation and the Cyberspace Administration of China — has become a recurring feature of the tech landscape, following high-profile enforcement actions against other internet giants in recent years.

Trip.com’s simultaneous exposure to slowing travel demand and an unresolved antitrust case places it in a uniquely pressured position among its peers.

What’s next

Investors will be watching for any update from SAMR on the investigation’s timeline, as well as whether Q2 bookings stabilise if energy prices ease or geopolitical tensions soften. The trajectory of long-haul international air capacity into China will be the single most important demand variable to monitor in the second half of 2026.
