How Crucial is Managing Underwriting Expenses to BRK.B's Profits?
Read MoreHide Full Article
Key Takeaways
BRK.B's insurance units rely on disciplined underwriting expense management to sustain profits.
Effective cost control boosts BRK.B's combined ratio and strengthens its investment float.
BRK.B stock is up 8% YTD. The consensus estimate for 2025 EPS indicates a year-over-year decline.
Berkshire Hathaway’s (BRK.B - Free Report) insurance operations serve as the cornerstone of its business model and remain a key growth engine. GEICO, Berkshire Hathaway Reinsurance Group and Berkshire Hathaway Primary Group are the pillars of its business. Their profitability depends on how effectively they manage underwriting expense, which is actually operating costs comprising commissions, salaries, marketing and advertising expenses, policy acquisition costs, as well as technology, data, and regulatory costs.
Since Berkshire’s insurance subsidiaries provide not only underwriting income but also valuable float, the disciplined management of underwriting expense directly impacts both near-term earnings and long-term compounding capacity. Efficiently controlling underwriting costs also helps Berkshire maintain pricing at a competitive rate without compromising on profitability. Accelerated digitalization plays an important role in managing underwriting expenses.
When underwriting expenses are well controlled, Berkshire’s combined ratio, the measure of underwriting profitability for an insurer, improves too, with the loss ratio being a component of the combined ratio. Delivering underwriting profits helps generate float that can be reinvested across its vast investment portfolio, creating amplified value over time.
Underwriting expenses have gone up in the last two years, reflecting higher volumes of business. However, they are not just a cost item but an important driver of BRK.B’s profitability. Effective management strengthens underwriting results, supports float stability, fuels investment firepower and sustains Berkshire’s long-term intrinsic value growth.
What About BRK.B’s Peers?

When Progressive effectively controls these costs, it drives underwriting gains, maintains competitive pricing and secures sustainable long-term growth.
The same holds true for Allstate Corporation (ALL - Free Report) . As a top personal lines insurer, Allstate depends on controlling underwriting expenses to sustain profitability. When Allstate manages these effectively, it strengthens underwriting margins, ensures earnings stability and secures long-term value creation for shareholders.
