While profitability is essential, it doesn’t guarantee long-term success. Some companies that rest on their margins will lose ground as competition intensifies - as Jeff Bezos said, "Your margin is my opportunity".

Profits are valuable, but they’re not everything. At StockStory, we help you identify the companies that have real staying power. Keeping that in mind, here are three profitable companies to avoid and some better opportunities instead.

Palo Alto Networks (PANW)

Trailing 12-Month GAAP Operating Margin: 11.1%

Founded in 2005 by cybersecurity engineer Nir Zuk, Palo Alto Networks (NASDAQ: PANW) makes hardware and software cybersecurity products that protect companies from cyberattacks, breaches, and malware threats.

Why Does PANW Worry Us?

1. Annual revenue growth of 19.7% over the last three years was below our standards for the software sector
2. Offerings struggled to generate meaningful interest as its average billings growth of 3% over the last year did not impress

Palo Alto Networks’s stock price of $201.40 implies a valuation ratio of 14.1x forward price-to-sales. Check out our free in-depth research report to learn more about why PANW doesn’t pass our bar.

Knight-Swift Transportation (KNX)

Trailing 12-Month GAAP Operating Margin: 3.9%

Covering 1.6 billion loaded miles in 2023 alone, Knight-Swift Transportation (NYSE: KNX) offers less-than-truckload and full truckload delivery services.

Why Should You Sell KNX?

1. Annual revenue growth of 1.2% over the last two years was below our standards for the industrials sector
2. Free cash flow margin dropped by 9.5 percentage points over the last five years, implying the company became more capital intensive as competition picked up
3. Diminishing returns on capital from an already low starting point show that neither management’s prior nor current bets are going as planned

At $47.39 per share, Knight-Swift Transportation trades at 24.2x forward P/E. Dive into our free research report to see why there are better opportunities than KNX.

Labcorp (LH)

Trailing 12-Month GAAP Operating Margin: 8.3%

With over 600 million tests performed annually and involvement in 90% of FDA-approved drugs in 2023, Labcorp (NYSE: LH) provides laboratory testing services and drug development solutions to doctors, hospitals, pharmaceutical companies, and patients worldwide.

Why Are We Cautious About LH?

1. Core business is underperforming as its organic revenue has disappointed over the past two years, suggesting it might need acquisitions to stimulate growth
2. Efficiency has decreased over the last five years as its adjusted operating margin fell by 13.3 percentage points
3. Waning returns on capital imply its previous profit engines are losing steam

Labcorp is trading at $261.89 per share, or 15.9x forward P/E. To fully understand why you should be careful with LH, check out our full research report (it’s free).
