    Investigation into contractor labor conditions at Brazil factory and prosecutors' lawsuit

    In late 2024, Brazilian authorities investigated the construction site of BYD's factory, alleging that contractor workers' working and living conditions were suspected of constituting slavery-like labor. BYD terminated contracts with the relevant contractors, and the contractors denied the allegations. In 2025, prosecutors sued BYD and the contractors, seeking damages; the company said it was cooperating with the investigation. The investigation and lawsuit are not equivalent to a final conviction.
