The transaction, having been approved by Lubrizol shareholders and having met all U.S. and non-U.S. regulatory filing requirements, is valued at approximately $9.7 billion, including approximately $0.7 billion in net debt.

“Lubrizol is a great addition to the Berkshire Hathaway family of companies,” said Warren Buffett, Berkshire Hathaway chief executive officer. “We expect to see continued strong performance from the company as it executes its growth strategies.”
