Warren Buffett and Berkshire Hathaway
The company’s publicly available archive of annual shareholder letters.
Free online letter archive
Original letters in the company’s free archive.
Inside the book
Berkshire’s shareholder letters offer a sequence of business decisions recorded across changing economic conditions. The free archive lets you move year by year instead of relying on quotations removed from their original setting. Read each letter alongside the corresponding annual report, then compare the discussion with what happened in later years. This is a primary-source reading project: the writer is explaining the company’s choices to its owners. Perimeter’s questions below are prompts for your own analysis, rather than a substitute for the full letters or financial statements.
Readers who want to study a company through its own dated disclosures, compare decisions over time, and build a primary-source research habit.
