3 Profitable Stocks with Mounting Challenges

NSSC Cover Image

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.

Not all profitable companies are created equal, and that’s why we built StockStory - to help you find the ones that truly shine bright. Keeping that in mind, here are three profitable companies that don’t make the cut and some better opportunities instead.

Napco (NSSC)

Trailing 12-Month GAAP Operating Margin: 27.5%

Protecting everything from schools to government facilities since 1969, Napco Security Technologies (NASDAQ: NSSC) manufactures electronic security devices, access control systems, and communication services for intrusion and fire alarm systems.

Why Do We Think Twice About NSSC?

  1. 3.7% annual revenue growth over the last two years was slower than its business services peers
  2. Revenue base of $181.2 million puts it at a disadvantage compared to larger competitors exhibiting economies of scale
  3. Demand will likely fall over the next 12 months as Wall Street expects flat revenue

At $30.01 per share, Napco trades at 25.8x forward P/E. To fully understand why you should be careful with NSSC, check out our full research report (it’s free).

Kadant (KAI)

Trailing 12-Month GAAP Operating Margin: 16.3%

Headquartered in Massachusetts, Kadant (NYSE: KAI) is a global supplier of high-value, critical components and engineered systems used in process industries worldwide.

Why Does KAI Fall Short?

  1. Sales trends were unexciting over the last two years as its 7.2% annual growth was below the typical industrials company
  2. Projected sales are flat for the next 12 months, implying demand will slow from its two-year trend
  3. Earnings growth underperformed the sector average over the last two years as its EPS grew by just 3.4% annually

Kadant’s stock price of $329.87 implies a valuation ratio of 32.5x forward P/E. If you’re considering KAI for your portfolio, see our FREE research report to learn more.

Luxfer (LXFR)

Trailing 12-Month GAAP Operating Margin: 10.6%

With its magnesium alloys used in the construction of the famous Spirit of St. Louis aircraft, Luxfer (NYSE: LXFR) offers specialized materials, components, and gas containment devices to various industries.

Why Should You Sell LXFR?

  1. Sales trends were unexciting over the last one years as its 1.6% annual growth was below the typical industrials company
  2. Free cash flow margin dropped by 8.7 percentage points over the last five years, implying the company became more capital intensive as competition picked up
  3. Waning returns on capital imply its previous profit engines are losing steam

Luxfer is trading at $12.68 per share, or 12.1x forward P/E. Check out our free in-depth research report to learn more about why LXFR doesn’t pass our bar.
