RT Surges 12% after Securing Key Chiang Mai Infrastructure Projects

Today (December 4, 2025), the share price of Right Tunnelling Public Company Limited (SET: RT) in the morning session closed at THB 0.28 per share, up by 0.03 point or 12%, with the trading value of THB 1.23 million. This uptick was driven by the news that the company has secured a construction agreement.

Mr. Chawalit Tanomtin, Chief Executive Officer of RT, stated that the company has won a bid for the construction of a water delivery tunnel and related buildings, including other components, in the Mae Taeng–Mae Ngat segment, Contract 2.

This contract is part of the project to increase water volume at the Mae Kuang Udom Thara Dam Reservoir, Chiang Mai Province, under the Royal Irrigation Department, with a project value of THB 2.8 billion.

The company is currently awaiting to be called for contract signing within this month and expects to commence construction in early 2026.

Contract 2 continues from Contract 1, which the company executed and delivered in August 2024, demonstrating RT’s expertise and experience in projects within this area.

Additionally, the company has won seven Slope Protection contracts worth approximately THB 85 million combined and is now waiting to be called for contract signing within this year. Securing these projects will support the company’s backlog, increasing it from THB 4.52 billion as of September 30, 2025, to THB 7.3 billion at the end of 2025.

“This securing of these projects further stabilizes our backlog over the long term and aligns with the company’s core expertise, reflecting RT’s role in developing the nation’s key infrastructure. The company focuses on efficient project management, cost control discipline, and stringent cash flow management, along with systematic resource management to ensure project delivery within the set timeframe,” said Mr. Chawalit.
