Explore the valuation, bull and bear cases for Berkshire Hathaway Class B (BRK.B) in 2026.

What the Business Does

Berkshire Hathaway Class B (BRK.B) operates in the financial sector, specifically focusing on FIRE, marine, and casualty insurance. The company has built a diversified portfolio that includes railroads, energy, and consumer businesses. This broad base helps cushion the impact from any single segment shock, providing a level of stability that is often sought after by investors.

The Buffett-Framework Verdict

According to the Buffett-framework analysis, Berkshire Hathaway Class B scores a total of 20 out of 100, resulting in a grade of D. The key components of this score include:

• Moat: 0 - The assessment indicates a lack of verified margins or returns, with critical figures like gross margin and return on invested capital (ROIC) remaining unknown.
• Durability: 20 - The company does not demonstrate strong durability as the data does not support it being a reliable compounder.
• Management: 31 - Management has not diluted shares, and their capital allocation discipline is commendable, yet overall performance is hampered by other factors.
• Valuation: 0 - The trailing P/E ratio of 182 indicates a severe valuation concern, leaving no margin for error.
• Financial Health: 50 - The company maintains a strong balance sheet, reflecting solid financial health despite the other weaknesses.

The verdict concludes that while Berkshire Hathaway has a fortress balance sheet, its current price does not justify its trailing earnings, marking it as a sell.

Valuation and Margin of Safety

Berkshire Hathaway Class B is currently priced at $498.66. With a trailing P/E of 182, the valuation is a significant concern. This high P/E ratio translates to an earnings yield of only 0.55%, which suggests that investors are paying a premium for earnings that may not sustain or grow.

The company's market capitalization stands at approximately $1.08 trillion, but the lack of measurable growth in revenue and earnings per share (EPS) raises questions about the sustainability of this valuation. Without solid growth metrics, the margin of safety for potential investments appears thin.

The Bull Case

Despite the valuation concerns, there are some strengths worth noting:

• Strong Financial Health: The company’s financial health score of 50 is the highest among the five pillars analyzed, indicating a solid balance sheet.
• No Share Dilution: The share count has remained stable, ensuring that existing owners are not being diluted.
• Capital Allocation: A disciplined approach to capital allocation enhances the management score to 31, suggesting that the company is retaining capital wisely.
• Diversification: The diversified portfolio across various sectors may provide a buffer against downturns in specific industries.

These factors present a case for long-term investors who believe in the company’s management and its ability to navigate economic fluctuations.

The Bear Case

On the flip side, several concerns cannot be overlooked:

• Extreme Valuation: The primary dealbreaker is the P/E ratio of 182, signaling that the market is overvaluing the company's earnings.
• Lack of Measurable Growth: The absence of growth metrics, such as revenue and EPS growth, raises doubts about the company's future performance.
• Uncertain Earnings: The reliance on mark-to-market portfolio gains to report earnings makes the P/E an unreliable indicator.
• Moat and Durability: The moat score of 0 and a durability score of 20 imply that the company lacks a competitive edge and does not show signs of being a durable compounder.

These factors suggest that investors should approach Berkshire Hathaway Class B with caution, particularly in light of its current valuation.

The Bottom Line

Berkshire Hathaway Class B presents a complex case for investors. While it boasts a strong balance sheet and disciplined management, the extreme valuation and lack of measurable growth metrics pose significant risks. The company's current P/E of 182 is a major concern, indicating that the stock may be overvalued at its current price of $498.66.
