Koh Brothers Eco Engineering Faces S$57.6m Legal Liabilities Ahead of SGX Mainboard Move
Singapore's Koh Brothers Eco Engineering disclosed S$57.6 million in potential legal liabilities. This news came hours before shareholders approved its transfer to the Singapore Exchange mainboard.

Major Liabilities Disclosed Before Mainboard Vote
Singapore-listed Koh Brothers Eco Engineering disclosed S$57.6 million in potential legal liabilities on Tuesday. This news emerged just hours before an extraordinary general meeting. At that meeting, shareholders approved the company's transfer to the Singapore Exchange (SGX) mainboard.
The engineering and construction firm faces these substantial liabilities from three major legal disputes. These include a S$20.5 million joint-venture (JV) counterclaim, a S$23.3 million consortium arbitration, and a subcontractor claim up to S$13.78 million. The company received in-principle approval for the mainboard move on July 1. It stated the transfer would broaden its investor base and improve share liquidity.
Details of Joint-Venture and Consortium Disputes
The most immediate issue involves the JV counterclaim. A subsidiary, Koh Brothers Building & Civil Engineering Contractor (KBCE), had applications to set aside partial arbitration awards dismissed by the Singapore High Court on August 6. The JV partner subsequently applied for final payment orders on August 7. Koh Brothers estimates its maximum exposure at S$20.5 million.
However, the JV account still holds over S$40 million in undistributed funds. Separately, consortium partners seek S$23.3 million. This relates to KBCE’s alleged failure to pay its share of capital injections. A hearing for this dispute has been postponed indefinitely.
Subcontractor Suit and Company Viability
A former subcontractor is suing KBCE and non-executive chairman Koh Keng Siang. The claim, ranging between S$9.18 million and S$13.78 million, alleges wrongful termination and conspiracy. The parties have agreed to mediation. Koh Brothers intends to file a counterclaim and has not yet made financial provisions for this suit.
Despite these legal proceedings, the company maintains they do not significantly doubt its viability as a going concern. It cited a net asset position of S$124.7 million as of June 30. Its order book stood at S$1 billion on August 5.
Financial Performance and Market Reaction
Koh Brothers Eco Engineering recorded a S$5.7 million loss for the first half, reversing a S$3 million profit in H1 2025. This was due to a 39 per cent increase in cost of sales, driven by higher material and procurement costs. Geopolitical conflicts and supply-chain disruptions contributed to these rising expenses.
The company expects the consortium and subcontractor disputes will not conclude within the next 12 months. Shares in Koh Brothers Eco Engineering fell 9.6 per cent, or S$0.011, to close at S$0.103 on Tuesday. Investors will closely monitor the progress of these legal challenges.
