Tata Steel , one of India's leading steel manufacturers, has announced a strategic move to strengthen its presence in the South-East Asian market. The company's indirect subsidiary, Siam Industrial Wire Company Limited (SIW), has acquired the remaining 40% stake in TSN Wires Company Limited from Nichia Steel Works Ltd. for a nominal sum of THB 100 (approximately ₹270).
Acquisition Details
The acquisition, executed through a Share Purchase Agreement on July 31, 2025, transforms TSN Wires from a joint venture into a wholly owned subsidiary of Tata Steel. This move is expected to enhance synergies and improve management efficiency between SIW and TSN Wires, both of which are part of Tata Steel's South-East Asia business.
About TSN Wires
TSN Wires, incorporated on April 11, 2012, is a Thailand-based downstream steel wires company with a production capacity of 41,000 tonnes per annum. The company operates in Thailand's domestic market and certain export markets, focusing on premium steel wire segments.
Financial Performance
TSN Wires has faced financial challenges in recent years, as evidenced by its financial results:
Fiscal Year | Turnover (₹ crore) | Profit After Tax (₹ crore) | Net Worth (₹ crore) |
---|---|---|---|
FY25 | 275.00 | -10.00 | -10.00 |
FY24 | 251.00 | -17.00 | 1.00 |
FY23 | 267.00 | -14.00 | 19.00 |
Despite the company's recent losses and negative net worth, Tata Steel appears to see potential in fully integrating TSN Wires into its operations.
Strategic Implications
The acquisition aligns with Tata Steel's strategy to strengthen its downstream capabilities and expand its presence in the South-East Asian market. By taking full control of TSN Wires, Tata Steel can potentially streamline operations, reduce costs, and leverage synergies between SIW and TSN Wires.
Regulatory Aspects
The transaction does not require any governmental or regulatory approvals and is scheduled to be completed within one month of the Share Purchase Agreement execution. This acquisition falls outside the purview of related party transactions.
As Tata Steel continues to expand its global footprint, this move underscores the company's commitment to strengthening its position in key markets and optimizing its operational portfolio. The nominal consideration for the acquisition suggests that Tata Steel is focused on the strategic value of full ownership rather than immediate financial gains from the transaction.
