Tata Power Shares Fall After Singapore Court Rejects Award Challenge
Tata Power had a disagreement with Kleros Capital about a coal project in Russia.
The companies discussed working together and shared confidential information.
Their partnership ended in 2016.
Tata Power later bid for the same coal deposit through its Russian subsidiary and won the licence.
Kleros said Tata Power improperly used information from their earlier discussions.
An arbitration tribunal ordered Tata Power to pay $490.32 million, plus interest and costs.
Tata Power challenged that decision in a Singapore court, but the court rejected the challenge.
Tata Power plans to appeal the ruling.
Investors are worried that the possible payment could affect the company’s money and future spending.
Tata Power shares fell as much as 4.7% after a Singapore court rejected challenges to a $490.32 million arbitration award.
The dispute concerns a Russian coal deposit and confidential information shared during proposed partnership talks beginning in 2013.
Kleros Capital alleged Tata Power used shared geological and economic data to secure the deposit’s 2017 mining licence.
The award includes 5.33% annual interest, legal costs and arbitration expenses, potentially taking total liability above $640 million.
Tata Power said it plans to appeal within 28 days, while investors are assessing effects on provisions, cash flow, debt and renewable-energy spending.
