Berkshire Hathaway Inc: what insiders have been doing
Headquartered in Omaha, United States, Berkshire Hathaway Inc belongs to the Banks sector and traces its origins to 1955. Filings by its managers are published through SEC (Form 4). From 24 October 2025 to 24 October 2026, the disclosure feed for Berkshire Hathaway Inc logged 21 filings by 4 insiders.
Both sides are active: 3 purchases worth €217k and 1 sale worth €17.5M, from 1 insider and 1 insider respectively. Netting one side against the other leaves €17.3M of net selling. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. One trade stands out by size: a sale of €17.5M from Jain Ajit, disclosed on 29 September 2026.
Compared with its exchange (2,023 companies, median 41 filings), a count of 21 filings is below the norm. The full history, which starts in 2006, counts 131 purchases against 1,791 sales. In its latest annual report filed with the SEC (10-K, fiscal year ended 31 December 2025), the company reported revenue of 371.44 bn USD and net income of 66.97 bn USD.
The most recent open-market purchase was published on 13 August 2026, 72 days ago. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 1 day. For comparison, the SEC allows two business days to file a Form 4.
Elsewhere in the same sector, our signals recently picked up insider purchases at BAWAG Group AG and ASR Nederland N.V. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.

About Berkshire Hathaway Inc
Berkshire Hathaway Inc. is a U.S.-listed conglomerate, traded in the American market on NYSE/NASDAQ terms, with its Class A shares BRK.A primarily associated with the NYSE. The company is headquartered in Omaha, Nebraska, United States, where it has remained rooted for decades. Berkshire’s identity is closely tied to Warren Buffett, who reshaped a former textile business into one of the world’s most diversified capital-allocation platforms. Today, Berkshire operates as a decentralized holding company with a long-term ownership mindset, strong cash generation, and a highly disciplined approach to capital deployment.
The group’s business model rests on several core pillars. First is insurance, which is the economic engine of Berkshire. Its insurance operations include GEICO, Berkshire Hathaway Primary Group, and Berkshire Hathaway Reinsurance Group. Insurance provides underwriting profits when pricing is favorable and, crucially, generates float that Berkshire can invest over time. The second major pillar is BNSF, one of the largest freight rail networks in North America, which gives Berkshire exposure to essential transportation infrastructure. A third pillar is Berkshire Hathaway Energy, a regulated utility and energy platform active in power generation, transmission, distribution, and related energy services. Beyond that, Berkshire owns a broad set of manufacturing, service, retail, and distribution businesses across industrial, consumer, and logistics-related niches.

Berkshire’s competitive position is unusual. Few companies combine large-scale insurance, a strategic rail franchise, regulated utilities, and a portfolio of private operating businesses and marketable securities with similar breadth. This diversification helps reduce reliance on any single end market, but it also means the company carries substantial capital intensity and earnings exposure across multiple cycles. Berkshire is also a major investor in public equities, so its reported results can be materially influenced by market-driven gains and losses on its investment portfolio.
Geographically, Berkshire remains predominantly U.S.-centered operationally, although some subsidiaries have international exposure, especially in insurance and certain industrial businesses. The latest annual reporting shows a very broad operating footprint, with major groupings including insurance, BNSF, BHE, manufacturing, service and retailing, McLane, and Pilot. The company’s 2025 annual report highlights the scale of capital employed across BHE, BNSF and the industrial platform, underscoring the defensive yet capital-heavy nature of the model.
Recent developments are also important. Berkshire’s 2025 annual report shows Gregory E. Abel as President and Chief Executive Officer in 2026, reinforcing the succession transition away from the Buffett era. The same filing also disclosed significant investment impairments related to Kraft Heinz and Occidental, reminding investors that Berkshire’s results still reflect volatility in its listed equity portfolio. For French-speaking investors, Berkshire Hathaway remains a benchmark U.S. holding company: a rare blend of insurance, infrastructure, energy, and long-duration capital allocation on the NYSE/NASDAQ market in the United States.
