Warren Buffett used to give a lot of money to the Gates Foundation, but he's stopped now. Even though he's not giving them money anymore, the things he invested in are still in the foundation's portfolio. These things are like boring businesses that Buffett likes to buy and hold onto for a long time.
Analysis
Warren Buffett's Influence on the Gates Foundation's Portfolio
Warren Buffett's decision to cut ties with the Gates Foundation is a significant development, especially considering the influence he has had on the nonprofit's investment style. Since 2006, Buffett has donated over $47 billion worth of Berkshire Hathaway stock to the Gates Foundation. However, despite his decision to suspend his annual donation, his influence remains evident in the nonprofit's trust portfolio.
The Top Holdings of the Gates Foundation's Portfolio
The Gates Foundation's top four holdings, which account for approximately 79% of the trust's $34 billion stock portfolio, are Berkshire Hathaway, WM, Caterpillar, and Canadian National Railway. These companies are the kinds of boring businesses Buffett would buy and hold for decades. Berkshire Hathaway, the largest holding in the portfolio, is a value stock that has historically outperformed in periods of volatility and downward pressure on stocks.
WM: A Boring Business with a Strong Track Record
WM, formerly known as Waste Management, is the largest waste hauler in the United States. Its landfill portfolio is practically impossible to replicate due to regulatory restrictions, making it a key facility for smaller competitors. WM's core waste-hauling business delivers an excellent operating margin, enabling it to expand horizontally into new businesses. Most recently, it acquired Stericycle, rebranding it as WM Healthcare Solutions to expand the business.
Caterpillar: A Railroad Business with a Strong Track Record
Caterpillar makes the iconic yellow construction and mining equipment found on worksites for decades. The company has recently seen earnings boom amid massive spending from hyperscalers for AI data center build-outs. Management has moved to capitalize on that trend in the long term by focusing on recurring services for its equipment, which could help reduce the cyclicality of large-scale infrastructure projects.
Canadian National Railway: A Railroad Business with a Strong Track Record
One of Buffett's biggest investments ever was the purchase of Burlington Northern Santa Fe. The railroad business is one Buffett understands, with its clear returns on capital. The Gates Foundation holds a stake in its competitor, Canadian National Railway, Canada's largest railway. The current investment is worth about $6.6 billion. The railroad industry, Canadian National in particular, is very attractive for several reasons. First, there's a high barrier to entry. Laying down or acquiring track is very capital-intensive. Canadian National has a tri-coastal network that spans East to West in Canada and runs South through the Midwest United States to the Gulf of Mexico. The railroads also benefit from economies of scale, which have been amplified by industrywide consolidation.
