Berkshire Hathaway (BRKA)(BRKB) is widely known as a conglomerate combining a massive stock portfolio with wholly owned businesses like GEICO Insurance, Duracell, and Shaw flooring.
What investors may be underestimating, however, is just how much raw cash one of those wholly owned businesses is quietly generating every single year.
That business is BNSF, the railroad giant Berkshire acquired in 2010 for $34.5 billion, a deal that has since become one of the most lucrative acquisitions in corporate history.
As Greg Abel noted in his 2025 letter to Berkshire Hathaway shareholders, BNSF generated $8.1 billion in operating earnings last year, handing $4.4 billion of that back to Berkshire as a cash dividend.
That payout was slightly above the five-year average of $4.1 billion, reflecting consistent and growing cash generation from the railroad over an extended period.
Measured against the original $34.5 billion purchase price from 2010, that $4.4 billion dividend translates into an effective yield of 12.7%, a figure that excludes any appreciation in BNSF’s underlying value.
Although Berkshire does not publish a specific valuation for BNSF, estimates of its current market value range from $75 billion to as much as $200 billion, according to various analyst assessments.
Warren Buffett himself acknowledged the railroad’s importance, stating that BNSF is Berkshire’s second-most-valuable asset, driven primarily by the substantial and reliable cash it produces year after year.
Through the first half of 2026, BNSF has already generated just over $2.9 billion in operating earnings, representing growth of nearly 10% year over year and putting it on pace to match or exceed last year’s strong results.
That first-half figure alone accounts for more than one-tenth of Berkshire’s total operating earnings, underscoring just how significant a single railroad is to the broader conglomerate’s financial performance.
With Berkshire currently sitting on $365.5 billion in uninvested cash, some shareholders may be wondering whether Greg Abel should pursue more outright acquisitions of cash-generating private businesses rather than deploying capital into publicly traded stocks.
The BNSF track record suggests that the private ownership model, when applied to the right business, can deliver compounding returns that are difficult for a traditional stock portfolio to replicate over time.
Sixteen years after the original acquisition, BNSF continues to demonstrate why patient capital allocated to durable, asset-heavy businesses remains one of the most powerful wealth-building strategies available to long-term investors.
