Warren Edward Buffett ( born August 30, 1930) is an American business magnate, investor, and philanthropist. He is currently the chairman and CEO of Berkshire Hathaway. As a result of his immense investment success, Buffett is one of the best-known fundamental investors in the world. As of June 2023, he possessed a net worth of $117 billion making him the fifth-richest person in the world.
Buffett was born in Omaha, Nebraska. The son of congressman and businessman Howard Buffett, he developed an interest in business and investing during his youth, eventually entering the Wharton School of the University of Pennsylvania in 1947 before transferring to and graduating from the University of Nebraska at 19. He went on to graduate from Columbia Business School, where he molded his investment philosophy around the concept of value investing pioneered by Benjamin Graham. He attended New York Institute of Finance to focus on his economics background and soon after began various investment business partnerships, including one with Graham. He created Buffett Partnership, Ltd in 1956 and his investment firm eventually acquired a textile manufacturing firm called Berkshire Hathaway, assuming its name to create a diversified holding company, and later as the company’s chairman and majority shareholder in 1970. In 1978, Charlie Munger joined Buffett as vice-chairman.
Since 1970, Buffett has presided as the chairman and largest shareholder of Berkshire Hathaway, one of America’s foremost holding companies and world’s leading corporate conglomerates. He has been referred to as the “Oracle” or “Sage” of Omaha by global media as a result of having accumulated a massive fortune derived from his business and investment success. He is noted for his adherence to the principles of value investing, and his personal frugality despite his vast wealth.
Buffett is also a noted philanthropist, having pledged to give away 99 percent of his fortune to philanthropic causes, primarily via the Bill & Melinda Gates Foundation. He founded The Giving Pledge in 2010 with Bill Gates, whereby billionaires pledge to give away at least half of their fortunes
Overview
Buffett is the chairman and largest shareholder of Berkshire Hathaway, the investment group that’s delivered a 19.8% compounded annual gain in market value since 1965. The Omaha, Nebraska-based company owns Geico, Clayton Homes and Dairy Queen, and has stakes in Coca-Cola and American Express.
The majority of Buffett’s fortune is derived from his interest in Berkshire Hathaway, a publicly traded investment company. Berkshire has delivered a compounded annual gain in per share market value of 19.8% since 1965, according to its 2023 letter to shareholders. Buffett owns about 37.9% of the Class A shares and less than 0.001% of the Class B shares, according to company filings from June and August 2023.
The billionaire also owns a less than 1% stake in U.S. Bancorp, according to a November 2022 13G filing.
In the 2011 shareholders letter, Buffett said Berkshire represents “more than 98%” of his net worth. Based on the value of his Berkshire shares on Feb. 25, 2012 — the date of the letter — the value of his non-Berkshire investments was calculated to be between $500 million and $900 million. In a separate letter to US Congressman Tim Huelskamp dated Oct. 11, 2011 Buffett said he had adjusted gross income of $62.9 million in 2010. Because Berkshire shares don’t pay dividends, the income implies that the non-Berkshire assets were valued at about $500 million if he had investment returns of 13%.
A non-Berkshire stock portfolio of $533 million was calculated for 2010, consisting of $61 million in Wells Fargo stock he held directly at that time based on SEC filings and $472 million in cash representing undisclosed share holdings. The value of the cash figure has been adjusted since then based on market performance, dividends, share purchases and taxes.
Debbie Bosanek, Buffett’s assistant, said he declined to comment.
Biography
Education: Columbia University, University of Nebraska
Nebraska-born Warren Buffett demonstrated an early knack for making money, delivering newspapers and selling candy and magazines door-to-door. He bought his first stock a year after visiting the New York Stock Exchange at age 11: three preferred shares of Cities Service. In 1950, he applied to Columbia University after discovering that Benjamin Graham and David Dodd, authors of the book “The Intelligent Investor,” taught there. After getting a master’s degree in economics, he worked as a securities analyst and stockbroker before starting his own investment firm, Buffett Partnership.
He began buying shares of distressed textile manufacturer Berkshire Hathaway in 1962, ultimately taking over as chairman and using it as a holding company. Since then, he’s returned more than 20% compounded annually. Known as a buy-and-hold value investor, Buffett typically buys stakes in — or purchases outright — companies whose business operations he says are easily understandable.
During the recession of the late 2000s, he served as a white knight-at-large, coming to the rescue of Goldman Sachs, General Electric and Swiss Re, while rejecting pleas from Lehman Brothers Holdings. He made what he called a big bet on the American economy in 2009, buying Burlington Northern Santa Fe for $34 billion.
Buffett has pledged to give away most of his fortune by his death, much of it going to the Bill & Melinda Gates Foundation.
