What does Berkshire Hathaway do? A Comprehensive Guide to Understanding the Conglomerate Powerhouse
Are you curious about the company led by the legendary investor Warren Buffett? Do you wonder how a single company can be involved in everything from insurance to railroads and even candy? If so, you've come to the right place! Let's embark on a journey to unravel the fascinating world of Berkshire Hathaway.
Berkshire Hathaway, headquartered in Omaha, Nebraska, isn't your typical company. It's a multinational conglomerate holding company. Think of it as a massive, diversified portfolio of businesses, both wholly owned and publicly traded investments, all under one roof. Its genius lies in its unique business model, built on the principles of value investing and long-term ownership, championed by Warren Buffett and his late partner, Charlie Munger.

| What Does Berkshire Hathaway Company Do |
Step 1: Get Your Head Around the Core Concept - It's a "Cash Machine"
Before we dive into the specifics, let's grasp the fundamental idea. Berkshire Hathaway is a cash-generating machine. The core of its business model revolves around its massive insurance operations, particularly GEICO. The insurance companies collect premiums from customers upfront and then pay out claims later. This creates a huge pool of money, known as the "float," which Berkshire can then invest.
Think of it this way: when you pay your car insurance premium to GEICO, that money doesn't just sit in a bank account. Berkshire takes that cash and puts it to work, investing it in other companies and assets. This float is a zero-cost source of capital, which is a massive advantage over other companies that have to borrow money or issue new shares to fund their investments. It’s a brilliant, self-perpetuating cycle of cash flow.
QuickTip: Look for patterns as you read.
Step 2: Unpack the Two Main Pillars of the Business
Berkshire Hathaway's operations can be broken down into two major, interconnected segments:
A. The Wholly-Owned Subsidiaries
This is where the magic happens on the operational side. Berkshire Hathaway owns and operates dozens of diverse businesses across various sectors. These aren't just small stakes; Berkshire owns them outright, gaining complete control over their operations. However, Buffett is known for giving significant autonomy to the managers of these companies. Here are some of the key areas and notable examples:
Insurance: This is the heart of the cash machine. Besides GEICO, Berkshire's insurance empire includes General Re and National Indemnity Company. These businesses are the primary source of the "float" we discussed earlier.
Rail Transportation: Berkshire owns BNSF Railway, one of the largest freight rail networks in North America. This is a massive, capital-intensive business that generates consistent and reliable revenue.
Utilities and Energy: Through Berkshire Hathaway Energy, the company owns utility businesses like PacifiCorp and NV Energy, as well as natural gas pipelines and renewable energy assets.
Manufacturing, Service, and Retailing: This is a vast and diverse category. It includes iconic brands like Dairy Queen, See's Candies, and Fruit of the Loom. It also encompasses a wide range of industrial and consumer goods companies, such as Precision Castparts Corp. (aerospace components), Marmon Holdings (industrial products), and Shaw Industries (flooring). You might be surprised to learn they own companies that make everything from bricks to motor homes and even private jets (NetJets)!
Building Products: They own companies like Acme Brick Company and Johns Manville, which produce building materials.
Retail: In addition to the well-known brands, they also own retailers like Nebraska Furniture Mart and Borsheims Fine Jewelry.
Tip: Read at your natural pace.
B. The Investment Portfolio
This is the second, equally important pillar. The cash generated by the wholly-owned businesses, particularly the insurance float, is deployed into a massive portfolio of publicly traded stocks. Warren Buffett and his team meticulously select companies to invest in for the long term. Their strategy is centered on value investing, which means buying shares of companies that are trading for less than their intrinsic value, and holding them for years, or even decades.
Their portfolio is a who's who of blue-chip American companies. As of early 2025, some of their largest holdings include:
Apple: A significant chunk of their portfolio is in the tech giant.
Bank of America: A major stake in the financial sector.
Coca-Cola: One of Buffett's longest-held and most famous investments.
American Express: Another long-term holding.
Chevron and Occidental Petroleum: Significant investments in the energy sector.
Kraft Heinz: A large stake in the food and beverage company.
Buffett often says they aren't "stock-pickers," but "business-pickers." This means they invest in a company's underlying business, not just its stock price, and they want to own a piece of a great business for a very long time.

Step 3: Understand the Synergy - How It All Comes Together
So, how do these two pillars work in harmony? The brilliant synergy is what makes Berkshire Hathaway so powerful.
QuickTip: Stop scrolling fast, start reading slow.
Cash Generation: The wholly-owned operating businesses, especially the insurance segment, generate a continuous stream of cash.
Capital Allocation: This cash is then allocated by the central management team, led by Buffett, to either acquire new businesses outright or to invest in publicly traded stocks.
Compounding Growth: The profits from the investments and the wholly-owned businesses are reinvested, leading to a powerful compounding effect over time.
Decentralized Management: The managers of the individual subsidiaries have a great deal of autonomy. This allows them to run their businesses effectively without micromanagement from the top, while still benefiting from the immense financial backing of Berkshire.
This model is a testament to the power of a diversified, decentralized, and patient approach to building wealth.
Step 4: A Look at the Leadership and Philosophy
The driving force behind this entire operation is, of course, Warren Buffett, and his late partner, Charlie Munger. Their investment philosophy is what defines Berkshire Hathaway.
Value Investing: Buying assets for less than they are worth.
"Moats": Investing in companies with a sustainable competitive advantage (a "moat") that protects them from competitors.
Long-Term Horizon: Holding investments for decades, not days or months.
Simplicity: Investing in businesses they can understand.
Patience and Discipline: Waiting for the right opportunity to invest and not being swayed by market fads or panics.
Their approach has created one of the most successful and admired companies in the world.
