Rio Tinto Slows Construction at Quebec Lithium Plant
Rio Tinto PLC's stock fell 5.13% as it hit a 20-day low amid broader market weakness, with the Nasdaq-100 down 0.91% and the S&P 500 down 0.68%.
The decline in Rio Tinto's stock is primarily due to the company's announcement of a slowdown in construction at its Nemaska lithium processing plant in Quebec. Although Rio Tinto plans to invest over $300 million in its Quebec lithium business in 2026, the construction pace will be reduced, with full construction expected to restart in 2027. This decision comes as several contractors halt work due to surging costs, which raises concerns about the project's timeline and overall execution.
This slowdown may impact investor sentiment regarding Rio Tinto's growth prospects in the lithium market, especially as the company plays a significant role in the lithium battery supply chain. The market's reaction reflects caution as investors assess the implications of this construction delay on future profitability.
