Why Does Scorpio Tankers Spark Debate?

Operating one of the youngest fleets in the industry, Scorpio Tankers (NYSE: STNG) is an international provider of marine transportation services, specializing in the shipment of refined petroleum.

Two Positive Attributes:

1. Elite Gross Margin Powers Best-In-Class Business Model

Gross profit margin is a critical metric to track because it sheds light on its pricing power, complexity of products, and ability to procure raw materials, equipment, and labor.

Scorpio Tankers has best-in-class unit economics for an industrials company, enabling it to invest in areas such as research and development. Its margin also signals it sells differentiated products, not commodities. As you can see below, it averaged an elite 68.8% gross margin over the last five years. That means Scorpio Tankers only paid its suppliers $31.17 for every $100 in revenue.

2. Excellent Free Cash Flow Margin Boosts Reinvestment Potential

Free cash flow isn’t a prominently featured metric in company financials and earnings releases, but we think it’s telling because it accounts for all operating and capital expenses, making it tough to manipulate. Cash is king.

Scorpio Tankers has shown terrific cash profitability, putting it in an advantageous position to invest in new products, return capital to investors, and consolidate the market during industry downturns. The company’s free cash flow margin was among the best in the industrials sector, averaging an eye-popping 50.5% over the last five years.

One Reason to Be Careful:

Decline in total vessels Points to Weak Demand

Revenue growth can be broken down into changes in price and volume (for companies like Scorpio Tankers, our preferred volume metric is total vessels). While both are important, the latter is the most critical to analyze because prices have a ceiling.

Scorpio Tankers’s total vessels came in at 91 in the latest quarter, and over the last two years, averaged 7.9% year-on-year declines. This performance was underwhelming and implies there may be increasing competition or market saturation. It also suggests Scorpio Tankers might have to lower prices or invest in product improvements to grow, factors that can hinder near-term profitability.

Final Judgment

Scorpio Tankers has huge potential even though it has some open questions, and with its shares topping the market in recent months, the stock trades at 6.8× forward P/E (or $76.44 per share).
