Whether you are researching Berkshire Hathaway Inc. on its own, evaluating NEC Corporation, or weighing the two companies side by side, the breakdown below highlights where each company leads and where the gap between Berkshire Hathaway Inc. and NEC Corporation is widest.

On the headline numbers, Berkshire Hathaway Inc. reports annual revenue of $371.4B against ~$24B for NEC Corporation, while their respective market capitalizations stand at $1.07T and $40.2B. Berkshire Hathaway Inc. is headquartered in United States and NEC Corporation in Japan, and those different home markets shape how each company competes.

Berkshire Hathaway Inc.: Berkshire Hathaway does not make a single product under its own name. It owns insurers (GEICO, General Re, National Indemnity, Alleghany), the BNSF railroad, Berkshire Hathaway Energy's regulated utilities and pipelines, manufacturers such as Precision Castparts, Lubrizol, Marmon and OxyChem, distributors such as McLane and Pilot, and consumer businesses such as See's Candies and Dairy Queen. On top of that sits an equity portfolio worth $297.8 billion at the end of 2025, whose five largest positions, American Express, Apple, Bank of America, Coca-Cola and Chevron, accounted for 65% of its value. About 387,800 people worked for Berkshire's businesses at the end of 2025, roughly 80% of them in the United States.

NEC Corporation: NEC Corporation is a Tokyo-based technology company with 101,800 employees and FY26/3 revenue of ~$24 billion (3,582.7 billion yen). It no longer makes consumer PCs or phones; instead it builds and runs IT systems for Japanese government and business, supplies telecom network gear and submarine cables, makes radar, satellite and defense communications systems, and sells biometric identification used at airports and borders. It is listed on the Tokyo Stock Exchange Prime Market under ticker 6701.

Berkshire Hathaway Inc. and NEC Corporation pursue distinct approaches to generating revenue, and understanding how each company operates is the foundation of any fair comparison between Berkshire Hathaway Inc. and NEC Corporation.

Berkshire Hathaway Inc. business model: Berkshire's business model is capital allocation on top of a decentralized group of operating companies. Subsidiary managers run their own businesses, with no corporate budget submissions and no committee structure at headquarters, and send surplus cash to Omaha. The chief executive then decides where it goes: into existing operations, new acquisitions such as the $9.7 billion purchase of OxyChem completed in January 2026, marketable equities, or Berkshire stock when it trades below estimated intrinsic value. Insurance is the core. Policyholder money held before claims are paid, which Berkshire calls float, reached $176 billion at the end of 2025, and the group has earned a pre-tax underwriting profit in each of the three years to 2025, so that float has cost less than nothing. Berkshire has not paid a dividend since 1967, which is why retained earnings and float, rather than outside capital, fund almost everything it buys.

NEC Corporation business model: NEC makes money by selling technology projects and recurring services to governments, enterprises and telecom carriers. In FY26/3 (year ended March 31, 2026), IT Services produced ~$16.8 billion (2,508.9 billion yen), about 70% of revenue: system integration, managed services and the BluStellar DX offering in Japan, plus digital government and digital finance software abroad through subsidiaries such as Avaloq, KMD and NEC Software Solutions UK. Social Infrastructure added ~$6.27 billion (935.3 billion yen), about 26%, from telecom network equipment and software, submarine cable systems, and aerospace and national security systems. Biometric identification (NeoFace face recognition, fingerprint and iris matching) is sold across both segments to airports, border agencies and police.

The durability of a company's moat often decides long-term winners. Here is how the competitive advantages of Berkshire Hathaway Inc. stack up against those of NEC Corporation.

Berkshire Hathaway Inc. competitive advantage: Berkshire's advantages are permanent capital, a balance sheet that stays liquid by design, and a reputation that brings sellers to it. It held $369.0 billion of cash, cash equivalents and Treasury Bills in its insurance and other businesses at the end of 2025 and carries limited debt, which is why it could supply capital to Goldman Sachs, General Electric and other companies during the 2008 crisis on terms no one else was offering. Owners of private businesses who care where their companies end up sell to Berkshire for the same reason: Bell Laboratories came to Berkshire in 2025 because its chief executive wrote to Buffett on behalf of the founder's daughters. Subsidiary managers also keep real autonomy, with no corporate budgets to submit and no quarterly earnings pressure.

NEC Corporation competitive advantage: NEC's edge comes from decades of trusted delivery to Japanese ministries, municipalities, the Ministry of Defense and NTT-group carriers, which makes it hard to displace on security-sensitive systems. Its face and fingerprint algorithms have repeatedly placed at or near the top of US NIST benchmark tests, which supports border-control and airport contracts abroad. It is also one of only a handful of companies (with SubCom and Alcatel Submarine Networks) able to build and lay transoceanic submarine cable systems.

Future prospects matter as much as current results. The growth strategies below explain how Berkshire Hathaway Inc. and NEC Corporation each plan to expand from here.

Berkshire Hathaway Inc. growth strategy: Berkshire's size limits what can move its results, so growth comes from large purchases, reinvestment inside existing businesses and buying back its own stock. Buffett described the 2009 BNSF agreement, a $34 billion investment in the railroad, as an all-in wager on the economic future of the United States. The 2025 and 2026 examples are smaller: a $9.7 billion purchase of Occidental's chemicals business, OxyChem, and the family-owned pest-control manufacturer Bell Laboratories. Abel has said Berkshire will buy productive businesses in preference to holding Treasuries, but will not stretch on price, which is why cash and Treasury holdings still exceeded $370 billion at the end of 2025 and no shares were repurchased that year. Berkshire also adds to listed holdings when prices suit it, paying $16.9 billion for equity securities during 2025.

NEC Corporation growth strategy: Under its 2025 Mid-term Management Plan, which NEC says it achieved in FY26/3, the company prioritized digital government and digital finance, 5G, and core DX (now branded BluStellar) as growth businesses while monitoring and pruning low-profit work. Current priorities include BluStellar consulting-led modernization in Japan, AI services including its cotomi language model and partnerships with US AI firms, defense and space systems, and international digital government software.
