Not all profitable companies are built to last - some rely on outdated models or unsustainable advantages.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. Keeping that in mind, here are three profitable companies to avoid and some better opportunities instead.
Papa John's (PZZA)
Trailing 12-Month GAAP Operating Margin: 4.3%
Founded by the eclectic John “Papa John” Schnatter, Papa John’s (NASDAQ:PZZA) is a globally recognized pizza delivery and carryout chain known for “better ingredients” and “better pizza”.
Why Are We Bearish on PZZA?
- Poor same-store sales performance over the past two years indicates it’s having trouble bringing new diners into its restaurants
- Projected sales decline of 5.7% for the next 12 months points to a tough demand environment ahead
- Expenses have increased as a percentage of revenue over the last year as its operating margin fell by 2.6 percentage points
At $19.81 per share, Papa John's trades at 17.1x forward P/E. Read our free research report to see why you should think twice about including PZZA in your portfolio.
Ameresco (AMRC)
Trailing 12-Month GAAP Operating Margin: 6.7%
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 Does AMRC Give Us Pause?
- Revenue growth over the past five years was nullified by the company’s new share issuances as its earnings per share fell by 15.7% annually
- Cash-burning tendencies make us wonder if it can sustainably generate shareholder value
- Short cash runway increases the probability of a capital raise that dilutes existing shareholders
Ameresco’s stock price of $21.19 implies a valuation ratio of 15.3x forward P/E. Check out our free in-depth research report to learn more about why AMRC doesn’t pass our bar.
Merck (MRK)
Trailing 12-Month GAAP Operating Margin: 9.6%
With roots dating back to 1891 and a portfolio that includes the blockbuster cancer immunotherapy Keytruda, Merck (NYSE:MRK) develops and sells prescription medicines, vaccines, and animal health products across oncology, infectious diseases, cardiovascular, and other therapeutic areas.
Why Are We Wary of MRK?
- Constant currency growth was below our standards over the past two years, suggesting it might need to invest in product improvements to get back on track
- Efficiency has decreased over the last five years as its adjusted operating margin fell by 19.9 percentage points
- Incremental sales over the last five years were much less profitable as its earnings per share fell by 11.1% annually while its revenue grew
Merck is trading at $146.15 per share, or 17x forward P/E. To fully understand why you should be careful with MRK, check out our full research report (it’s free).
