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 two profitable companies that balance growth and profitability and one best left off your watchlist.
One Stock to Sell:
Qualys (QLYS)
Trailing 12-Month GAAP Operating Margin: 34.4%
Originally developed to address the growing complexity of IT security in the cloud era, Qualys (NASDAQ: QLYS) provides a cloud-based platform that helps organizations identify, manage, and protect their IT assets from cyber threats across on-premises, cloud, and mobile environments.
Why Does QLYS Give Us Pause?
- Underwhelming ARR growth of 10.3% over the last year suggests the company faced challenges in acquiring and retaining long-term customers
- Estimated sales growth of 8.9% for the next 12 months is soft and implies weaker demand
- Operating margin expanded by 3.4 percentage points over the last year as it scaled and became more efficient
Qualys’s stock price of $181.91 implies a valuation ratio of 8.3x forward price-to-sales. Read our free research report to see why you should think twice about including QLYS in your portfolio.
Two Stocks to Watch:
TransDigm (TDG)
Trailing 12-Month GAAP Operating Margin: 46%
Supplying parts for nearly all aircraft currently in service, TransDigm (NYSE: TDG) develops and manufactures components and systems for military and commercial aviation.
What Makes TDG Stand Out?
- Average organic revenue growth of 9.3% over the past two years demonstrates its ability to expand independently without relying on acquisitions
- Share buybacks catapulted its annual earnings per share growth to 29.9%, which outperformed its revenue gains over the last five years
- Robust free cash flow margin of 20% gives it many options for capital deployment, and its improved cash conversion implies it’s becoming a less capital-intensive business
At $1,202 per share, TransDigm trades at 25.3x forward P/E. Is now a good time to buy? Find out in our full research report, it’s free.
RTX (RTX)
Trailing 12-Month GAAP Operating Margin: 11.2%
Originally focused on refrigeration technology, Raytheon (NSYE:RTX) provides a variety of products and services to the aerospace and defense industries.
Why Is RTX Interesting?
- Core business is healthy and doesn’t need acquisitions to boost sales as its organic revenue growth averaged 10.5% over the past two years
- Share buybacks catapulted its annual earnings per share growth to 16.3%, which outperformed its revenue gains over the last five years
- Free cash flow margin expanded by 5.2 percentage points over the last five years, providing additional flexibility for investments and share buybacks/dividends
RTX is trading at $210.68 per share, or 28.8x forward P/E. Is now the right time to buy? See for yourself in our in-depth research report, it’s free.
