Does Warren Buffett Know Something Wall Street Doesn't? Why the Billionaire Investor Owns This High-Yielding Dividend Stock.

Warren Buffett doesn't make many mistakes when it comes to investing, as evidenced by his supreme long-term track record in public markets. He and the team at Berkshire Hathaway (NYSE: BRK.B) seem to have made a mistake by investing in SiriusXM (NASDAQ: SIRI) -- at least, so far. The automotive satellite radio provider is down over 60% in the last five years, while the broad market indices have soared.

Today, the stock trades at a price-to-earnings (P/E) ratio of 8 and a dividend yield of 5%. Does Berkshire Hathaway see something in SiriusXM that the rest of the market is missing? Let's dive in further and investigate this fallen internet stock and see if it is a buy for your portfolio today.

Declining revenue, competitive threats

SiriusXM made its money selling satellite radio subscriptions in conjunction with automotive purchases. Today, this business is facing multiple headwinds with the rise of Spotify, Apple Music, and YouTube taking share from satellite radio for talk and music. Its subscribers stood at 32.86 million last quarter, which is below its user count at the end of 2018.

Lower subscriber figures have led to declining revenue, with sales now off 4.4% from all-time highs last quarter. This is coming at a time when the streaming music services such as Spotify are growing like gangbusters, which are putting a world of hurt on SiriusXM's business. With the rise of Google and Apple Car Play, users can stream the same applications in vehicles that they use on their phones, which has disrupted SiriusXM's competitive edge.

It has tried to fight back with a stand-alone SiriusXM streaming application, acquiring rights to podcasts, and even acquiring Pandora Radio back in the day. It has not lived up to expectations, with this other segment seeing a 2% decline in revenue year over year last quarter. Management is guiding for $1.15 billion in free cash flow this year, but that is still well below all-time highs set a few years ago. If revenue keeps sliding, free cash flow will eventually disappear.

Perhaps it wasn't a Buffett investment?

Just because a stock is owned by Berkshire Hathaway does not mean it was a Warren Buffett investment. The company has two investors -- Todd Combs and Ted Weschler -- who manage billions of dollars of investments. One of these investors may be the purchaser of SiriusXM stock instead of Buffett, who at this point only dabbles in investments that can move the needle for the trillion-dollar market-cap stock.

At a market cap of just $7 billion, SiriusXM is not going to be a meaningful contributor to Berkshire Hathaway's stock portfolio even if it goes up by 10 times. The company owns $2.8 billion worth of SiriusXM stock. If that stock is worth $28 billion someday, that is barely 2% of Berkshire's market value. A 10 times move upwards is highly unlikely too.

The truth behind SiriusXM stock

With a dividend yield of 5%, you might think SiriusXM stock is a buy just because Berkshire Hathaway owns it. In this case, following Berkshire Hathaway blindly has led an investor to lose money.

The problem with SiriusXM is not just its declining subscribers and declining revenue. It is the huge debt load carried on its balance sheet. The company has over $10 billion in long-term debt vs. its $1.1 billion in projected 2025 free cash flow. Free cash flow will decline if revenue keeps sliding. The debt is mostly due before 2030, meaning that SiriusXM is going to have to scramble to pay back these loans or refinance at higher interest rates. Either way, this is not good for shareholders.

SiriusXM is a stock with declining revenue and heavy indebtedness in a declining industry. Even with a high dividend yield of 5%, it is best to stay away from this stock. It's unclear what Berkshire Hathaway sees in this business.
