BRK.B's Insurance Business Grows Steadily: Can it Accelerate Growth?

Berkshire Hathaway's insurance operations, including GEICO and General Re, contribute roughly one-quarter of total revenues and are a key growth driver, with the insurance float rising from $114 billion in 2017 to $173 billion in Q1 2025. This float provides capital for strategic investments, enhancing returns and shareholder value; however, while revenue estimates for 2025 and 2026 indicate year-over-year increases, EPS estimates for Q2 and Q3 2025 have recently moved down.

Analysis

Berkshire Hathaway's (BRK.B) insurance operations are a fundamental pillar, contributing approximately one-quarter of total revenues and consistently generating underwriting profits. The segment's strategic importance is underscored by the substantial growth of its float, which increased from $114 billion in 2017 to $173 billion by the end of Q1 2025, providing significant capital for strategic investments and enhancing overall returns. Despite this operational strength, recent estimate revisions present a mixed outlook: Zacks Consensus Estimates for Q2 and Q3 2025 EPS have declined by 3% and 0.3% respectively over the past 30 days. While the full-year 2025 EPS estimate saw a slight upward revision of 0.2% recently, the overall 2025 EPS is still anticipated to show a year-over-year decline, contrasting with projected year-over-year revenue growth for 2025 and an expected increase in 2026 EPS. Shares of BRK.B have gained 8.9% year-to-date, underperforming the broader industry. The stock trades at a price-to-book ratio of 1.62, slightly above the industry average of 1.58, and carries a Zacks Value Score of D, suggesting a potentially expensive valuation. The upcoming leadership transition, with Greg Abel slated to become CEO on January 1, 2026, while Warren Buffett remains executive chairman, will be closely watched for continuity in strategy, particularly concerning the insurance-led model. The general sentiment surrounding the company, based on the provided signals, is mildly positive.

Key Decisions for Investors

• Investors should recognize the ongoing strength and float generation capabilities of BRK.B's core insurance business as a long-term positive driver.
• Closely monitor the upcoming CEO transition in early 2026 for any shifts in capital allocation strategy or operational management, although continuity is currently emphasized.
• Consider the near-term pressure on earnings, as evidenced by downward revisions for Q2 and Q3 2025 EPS and an anticipated overall decline in 2025 EPS, against the backdrop of projected revenue growth and a more positive 2026 EPS outlook.
• Evaluate the current valuation, with a price-to-book ratio slightly above the industry average and a 'D' Value Score, and weigh this against the company's fundamental strengths and recent share underperformance when making new investment or position adjustment decisions.
