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".

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 two profitable companies that leverage their financial strength to beat the competition and one that may face some trouble.

Trailing 12-Month GAAP Operating Margin: 68.7%

Created by Congress in 1987 to build a bridge between Wall Street and rural America, Farmer Mac (NYSE:AGM) provides a secondary market for agricultural and rural loans, helping lenders increase their liquidity and lending capacity to serve rural America.

Why Is AGM Not Exciting?

3.7% annual revenue growth over the last two years was slower than its financials peers

Earnings growth over the last two years fell short of the peer group average as its EPS only increased by 3.3% annually

Elevated debt-to-equity ratio of 19.8× suggests the firm is overleveraged and may struggle to secure additional financing

Farmer Mac is trading at $162.15 per share, or 8.5x forward P/E. To fully understand why you should be careful with AGM, check out our full research report (it’s free).

Trailing 12-Month GAAP Operating Margin: 7.2%

With its technology protecting workers in over 130 countries and equipment used in 80% of cancer centers worldwide, Mirion Technologies (NYSE:MIR) provides radiation detection, measurement, and monitoring solutions for medical, nuclear energy, defense, and scientific research applications.

Why Is MIR on Our Radar?

Market share has increased this cycle as its 11.8% annual revenue growth over the last five years was exceptional

Operating profits and efficiency rose over the last five years as it benefited from some fixed cost leverage

Free cash flow margin expanded by 11.1 percentage points over the last five years, providing additional flexibility for investments and share buybacks/dividends

Massive revenue base of $26.98 billion makes it a well-known name that influences purchasing decisions

Impressive free cash flow profitability enables the company to fund new investments or reward investors with share buybacks/dividends, and its improved cash conversion implies it’s becoming a less capital-intensive business
