Energy Future Holdings (EFH)

Energy Future Holdings (formerly TXU Corp) is the subject of one of Warren Buffett's most significant and publicly acknowledged capital allocation errors. Berkshire invested approximately $2 billion in EFH junior bonds, an investment that ultimately resulted in a substantial pre-tax loss.

🏁 Origin & The Thesis

In 2007, EFH was the target of a record-breaking $45 billion leveraged buyout led by KKR, TPG, and Goldman Sachs. Berkshire purchased ~$2 billion of the company's 10.875% junior bonds.

The investment was not a typical Berkshire "moat" play, but a commodity bet:

• The Bet: Buffett assumed that natural gas prices would rise, which would drive up the price of electricity and allow the highly-leveraged EFH to service its massive debt.
• The Error: Natural gas prices crashed over the following years (due to the fracking revolution), and EFH’s revenue was insufficient to cover its interest obligations.

🚀 Strategic Importance (as a Lesson)

Buffett used EFH in the 2011 Letter as a "teachable moment" for shareholders:

• Idiosyncratic Failure: He admitted that he purchased the bonds without consulting Charlie Munger. "That was a big mistake," he noted, emphasizing that Munger’s skepticism might have caught the flaw in the commodity-price assumption.
• The Institutional Imperative: The deal was part of a massive, fashionable LBO wave. Buffett's participation showed that even he was not immune to occasional errors of judgment when departing from his core strictly-defined circle of competence (predictable cash flows vs. commodity predictions).

📈 Outcome

• 2013-2014: Berkshire sold the EFH bonds for $259 million in 2013, avoiding the total wipeout when EFH filed for bankruptcy in 2014.
• The Loss: Berkshire finalized a pre-tax loss of $873 million on the investment. While the loss was small in the context of Berkshire's total capital, it remains one of the largest single-investment losses in Buffett's career, cementing the lesson of straying outside the Circle of Competence.

[!WARNING] EFH stands as a stark reminder that even the world's most disciplined capital allocator can fail when betting on commodity price directions rather than durable competitive advantages.
