3 Profitable Stocks with Questionable Fundamentals

Not all profitable companies are built to last - some rely on outdated models or unsustainable advantages. Just because a business is in the green today doesn’t mean it will thrive tomorrow.

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

Acushnet (GOLF)

Trailing 12-Month GAAP Operating Margin: 12.4%

Producer of the acclaimed Titleist Pro V1 golf ball, Acushnet (NYSE:GOLF) is a design and manufacturing company specializing in performance-driven golf products.

Why Is GOLF Risky?

  1. Lackluster 10.1% annual revenue growth over the last five years indicates the company is losing ground to competitors
  2. Lacking free cash flow generation means it has few chances to reinvest for growth, repurchase shares, or distribute capital
  3. Diminishing returns on capital from an already low starting point show that neither management’s prior nor current bets are going as planned

Acushnet’s stock price of $84.10 implies a valuation ratio of 21.3x forward P/E. If you’re considering GOLF for your portfolio, see our FREE research report to learn more.

Ameresco (AMRC)

Trailing 12-Month GAAP Operating Margin: 6.8%

Having played a role in upgrading the energy solutions of Alcatraz Island, Ameresco (NYSE:AMRC) provides energy and renewable energy solutions for various sectors.

Why Are We Hesitant About AMRC?

  1. Gross margin of 16.5% is below its competitors, leaving less money to invest in areas like marketing and R&D
  2. Cash-burning history makes us doubt the long-term viability of its business model
  3. Limited cash reserves may force the company to seek unfavorable financing terms that could dilute shareholders

Ameresco is trading at $34.74 per share, or 36.3x forward P/E. Read our free research report to see why you should think twice about including AMRC in your portfolio.

Bio-Techne (TECH)

Trailing 12-Month GAAP Operating Margin: 9%

With a catalog of hundreds of thousands of specialized biological products used in laboratories worldwide, Bio-Techne (NASDAQ:TECH) develops and manufactures specialized reagents, instruments, and services that help researchers study biological processes and enable diagnostic testing and cell therapy development.

Why Do We Pass on TECH?

  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. Smaller revenue base of $1.22 billion means it hasn’t achieved the economies of scale that some industry juggernauts enjoy
  3. 11.6 percentage point decline in its free cash flow margin over the last five years reflects the company’s increased investments to defend its market position

At $64.35 per share, Bio-Techne trades at 31.9x forward P/E. Dive into our free research report to see why there are better opportunities than TECH.
