Even if a company is profitable, it doesn’t always mean it’s a great investment. Some struggle to maintain growth, face looming threats, or fail to reinvest wisely, limiting their future potential.

A business making money today isn’t necessarily a winner, which is why we analyze companies across multiple dimensions at StockStory. That said, here are three profitable companies to steer clear of and a few better alternatives.

Tenable (TENB)

Trailing 12-Month GAAP Operating Margin: 1.7%

Starting with the widely-used Nessus vulnerability scanner first released in 1998, Tenable (NASDAQ:TENB) provides exposure management solutions that help organizations identify, assess, and prioritize cybersecurity vulnerabilities across their IT infrastructure and cloud environments.

Why Does TENB Give Us Pause?

  1. Customers had second thoughts about committing to its platform over the last year as its average billings growth of 6.9% underwhelmed
  2. Estimated sales growth of 6.8% for the next 12 months implies demand will slow from its two-year trend
  3. Operating margin improvement of 3.4 percentage points over the last year demonstrates its ability to scale efficiently

Tenable is trading at $26.14 per share, or 2.6x forward price-to-sales. If you’re considering TENB for your portfolio, see our FREE research report to learn more.

Advanced Energy (AEIS)

Trailing 12-Month GAAP Operating Margin: 10.8%

Pioneering technologies for radio frequency power delivery, Advanced Energy (NASDAQ:AEIS) provides power supplies, thermal management systems, and measurement and control instruments for various manufacturing processes.

Why Are We Wary of AEIS?

  1. Muted 5.6% annual revenue growth over the last five years shows its demand lagged behind its industrials peers
  2. Earnings growth underperformed the sector average over the last five years as its EPS grew by just 5.3% annually
  3. Shrinking returns on capital suggest that increasing competition is eating into the company’s profitability

Advanced Energy’s stock price of $322.55 implies a valuation ratio of 32.9x forward P/E. Dive into our free research report to see why there are better opportunities than AEIS.

United Airlines (UAL)

Trailing 12-Month GAAP Operating Margin: 8.4%

Founded in 1926, United Airlines Holdings (NASDAQ:UAL) operates a global airline network, providing passenger and cargo air transportation services across domestic and international routes.

Why Should You Dump UAL?

  1. Sluggish trends in its revenue passenger miles suggest customers aren’t adopting its solutions as quickly as the company hoped
  2. Poor expense management has led to an operating margin of 9.1% that is below the industry average
  3. Capital intensity will likely ramp up in the next year as its free cash flow margin is expected to contract by 5.5 percentage points

At $114.95 per share, United Airlines trades at 12.5x forward P/E. If you’re considering UAL for your portfolio, see our FREE research report to learn more.
