Warren Buffett built a reputation as one of the greatest investors due to his disciplined value investing approach. Maintaining a long-term perspective and prioritizing fundamentally sound companies with durable competitive advantages, Buffett has become a magician at finding undervalued stocks to build his multi-billion dollar portfolio. 

One of those companies is BYD (BYDDY -1.47%), an up-and-coming Chinese electric vehicle (EV) manufacturer. Initially investing $225 million in 2008, Buffett realized this obscure automaker checked all the right boxes to take the auto industry by storm one day. While recently selling some shares to secure profits, Buffett's stake in the company remains at just under 8% and is worth more than $5.5 billion today.

While we can't go back in time and invest when shares of BYD were trading for less than $5, the company's strong performance and promising growth prospects make it an appealing investment even at its current price.

A historic rise to the top

Starting out as a battery maker in the 1990s, BYD has used this experience to build an incredibly successful EV business. Today, BYD is the best-selling automaker in China and is slowly closing the gap to become the most productive and profitable EV maker in the world. 

Thanks to a record-breaking Q3, BYD has sold more than 2 million vehicles year to date (YTD), a 76% increase from a year ago. This surge in production helped the company overtake the top spot of total EV production worldwide, previously held by industry champion Tesla. Amidst the surge, BYD's profits YTD grew by nearly 142% compared to last year, now at more than $3 billion.

Yet the most attractive aspect of BYD is its high-profit margins. Coming in at roughly 22%, BYD can keep costs low due to its uniquely efficient, vertically integrated production model. Often, the most challenging aspect of manufacturing EVs is perfecting supply chain logistics around batteries. But thanks to BYD's origins as a battery manufacturer, it can overcome a crucial obstacle that prevents many other EV makers from scaling production.

Even better, BYD has specific divisions for every component of vehicle production, such as telematics assembly and air conditioners. This has enabled almost all components to be made entirely in-house. Add it all up, and what usually takes the average automaker around four years from start to finish takes BYD just 18 months.

Expanding abroad

With the Chinese market in firm grasp, BYD plans to expand to international markets. The company is building a factory in Thailand, which is set to begin production in 2024. In late June, BYD announced a new plant will be constructed in Brazil while deliveries in Mexico recently started as part of a strategy to expand in Latin America.

BYD is uniquely suited for success in middle-income countries due to its expansive suite of more than two dozen vehicles at a range of price points. While it offers high-end luxury EVs, BYD also caters to more cost-conscious consumers, with cars like its Seagull going for less than $11,000. 

Furthermore, BYD already has a considerable presence in countries such as Japan, India, Malaysia, Australia, and Singapore. Even though exports remain a small share of total sales, they are up significantly from almost being non-existent just a year ago and have plenty of room to grow.

The opportunity at hand

It is easy to see why BYD is one of only two auto companies to hold a spot in Buffett's portfolio. The company has a clear competitive advantage due to its experience with battery production and vertically integrated supply chain. In addition, it can flex its muscles even more by selling cars for cheap, putting added pressure on competitors.

With international expansion only in its beginning stages and trends in EV adoption continuing to grow, BYD is in a position to outperform over the long term. Yet, today, its price-to-earnings ratio is at its lowest level in over three years. 

Investors seeking to emulate Buffett's success can follow his strategy of acquiring companies with strong fundamentals at discounted prices, such as BYD. The company is well-positioned to become one of the leading automakers globally, and its history of success suggests that it has long-term growth potential.
