Overview

• Berkshire confirmed in its June 30 10-Q that it no longer holds BYD shares, and Berkshire Hathaway Energy had marked the investment at zero value as of March 31.
• The stake was trimmed steadily starting in mid-2022 and fell below Hong Kong’s 5% disclosure threshold in 2024, limiting visibility into the final sales.
• BYD stock fell roughly 3%–3.4% in Hong Kong trading after the confirmation of Berkshire’s full exit.
• Buffett’s 2008 investment of about $230 million generated outsized gains over the years, even as BYD now faces a domestic price war and a reported 30% year-on-year profit decline in the second quarter of 2025.
• Coverage also notes Berkshire sold about $4 billion of TSMC shares in a broader portfolio rethink that has included reassessing China-linked geopolitical risk.
