Koh Brothers Eco Engineering Limited on Aug, 18 2026 outlined the status and potential financial impact of three separate legal actions involving its wholly-owned unit, Koh Brothers Building & Civil Engineering Contractor (Pte.) Ltd.

The largest matter is the SCA Arbitration with a joint-venture partner, where the tribunal on Jul, 14 2025 valued the partner’s counterclaims at about 20.5 million Singapore dollars (excluding interest and costs) and Koh Brothers’ own claims at about 2.1 million Singapore dollars. Subsequent awards on Dec, 09 2025 fixed arbitration costs at 5.33 million Singapore dollars and 4.12 million U.S. dollars. The High Court dismissed Koh Brothers’ applications to set aside these awards on Aug, 06 2026, leaving them binding, while allocation issues between the joint-venture parties remain unresolved.

In a separate High Court suit, a former subcontractor is seeking damages of between 9.18 million and 13.78 million Singapore dollars from Koh Brothers and director Koh Keng Siang, alleging wrongful termination and conspiracy. The company denies the claims and is preparing a counterclaim exceeding the amount sought; mediation has been proposed.

A third case, the Consortium Arbitration, was started by joint-venture partners who claim 23.3 million Singapore dollars, or alternatively 20.7 million Singapore dollars, over alleged non-payment of capital contributions. Koh Brothers disputes both liability and quantum; the hearing has been deferred to a date to be fixed.

The group reported net assets of about 124.7 million Singapore dollars as of Jun, 30 2026 and said it does not expect the disputes to pose a material threat to its ability to continue as a going concern, assuming access to its share of more than 40 million Singapore dollars held in the joint-venture account related to the SCA matter.

Koh Brothers said it will update shareholders on any significant developments and urged investors to exercise caution when trading its shares.
