The total consideration represents a 43% premium over the book value and net asset value of SembEnviro and its subsidiaries as at June 30.

Sembcorp Industries has entered into a share purchase agreement to sell 100% of the shares in its wholly-owned subsidiary Sembcorp Environment (SembEnviro) to SBT Investment 2, a wholly-owned subsidiary of Indonesia Stock Exchange-listed PT TBS Energi Utama (TBS).

The total consideration for the proposed transaction is estimated at $405 million. This represents a 43% premium over the book value and net asset value of SembEnviro and its subsidiaries as at June 30, after taking into account the estimated pre-completion dividend to be distributed from SembEnviro group.

The proposed transaction aligns with Sembcorp's strategic plan and will sharpen its focus on growth in the energy sector to ensure strategic fit and maximise shareholder value, the company says in a filing.

TBS, through its subsidiaries, manages a waste management portfolio in Singapore and Indonesia. In Singapore, TBS owns and operates Asia Medical Enviro Services, which specialises in biohazardous and medical waste treatment services. 

With the proposed transaction, SembEnviro will transition to ownership under TBS, a strategic buyer committed to investing in and supporting the future growth and performance of SembEnviro group. 

To ensure continuity and best practices of the services provided, TBS has agreed to retain management and staff of SembEnviro group following the completion of the proposed transaction. Sembcorp will also provide transitional services to support a smooth handover and ensure continued provision of integrated waste management services by TBS.

The proposed transaction is expected to be completed by the first half of 2025.
