Bell Laboratories

Bell Laboratories is a premier manufacturer of rodent control products, acquired by Berkshire Hathaway in 2025.

📝 Business Overview & Acquisition Context

  • Acquisition (2025): Announced in the 2025 Letter, the acquisition originated when CEO Steve Levy sent a letter to Warren Buffett asking Berkshire to evaluate the business, which he was managing for the daughters of the late founder, Malcolm Stack.
  • The "Perfect" Inquiry: Greg Abel highlighted the letter as exemplary of the ideal Berkshire acquisition proposal. The letter outlined a business that meets a persistent, basic need (rodent control), and demonstrated:
    1. High operating margins.
    2. Very strong historical growth and future growth potential.
    3. An easily understandable and durable business model.
    4. A strong, committed management team.
  • The Heuristic (Size Constraint): In a classic Berkshire reflection, Greg Abel remarked that Bell Laboratories represents a business with durable advantages and excellent management, adding: "We only wish it had been ten times bigger." This highlights Berkshire's persistent challenge of size: finding capital-efficient businesses that can move the needle for a conglomerate of Berkshire's scale.

In 2025, our approach resulted in Berkshire announcing the acquisition of two very different businesses: OxyChem and Bell Laboratories. Last year, Warren received a letter from Steve Levy, Bell Laboratories’ CEO, asking that we look at the family-owned business he manages for the daughters of founder Malcolm Stack. Steve’s letter was perfect. Bell Laboratories meets a persistent need: rodent control. In Steve’s words, it possesses “high operating margins, very good historical growth and future growth potential, easy to understand and always needed, and a strong management team.” In our words: a business with durable advantages and long-term economic prospects run by excellent managers. We only wish it had been ten times bigger.
