Not all profitable companies are built to last - some rely on outdated models or unsustainable advantages.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.

Profits are valuable, but they’re not everything. At StockStory, we help you identify the companies that have real staying power. That said, here are two profitable companies that balance growth and profitability and one that may face some trouble.

One Stock to Sell:

SiteOne (SITE)

Trailing 12-Month GAAP Operating Margin: 5.1%

Known for distributing John Deere tractors and LESCO turf care products, SiteOne Landscape Supply (NYSE:SITE) provides landscaping products and services to professionals, including irrigation, lighting, and nursery supplies.

Why Is SITE Risky?

1. Organic revenue growth fell short of our benchmarks over the past two years and implies it may need to improve its products, pricing, or go-to-market strategy
2. Flat earnings per share over the last two years underperformed the sector average
3. Waning returns on capital imply its previous profit engines are losing steam

SiteOne is trading at $105.33 per share, or 23.7x forward P/E. Dive into our free research report to see why there are better opportunities than SITE.

Two Stocks to Watch:

Monolithic Power Systems (MPWR)

Trailing 12-Month GAAP Operating Margin: 27.1%

Founded in 1997 by its longtime CEO Michael Hsing, Monolithic Power Systems (NASDAQ:MPWR) is an analog and mixed signal chipmaker that specializes in power management chips meant to minimize total energy consumption.

Why Is MPWR a Top Pick?

1. Annual revenue growth of 25.9% over the past five years was outstanding, reflecting market share gains this cycle
2. Incremental sales significantly boosted profitability as its annual earnings per share growth of 27.7% over the last five years outstripped its revenue performance
3. Stellar returns on capital showcase management’s ability to surface highly profitable business ventures

At $1,284 per share, Monolithic Power Systems trades at 52.9x forward P/E. Is now the time to initiate a position? Find out in our full research report, it’s free.

Champion Homes (SKY)

Trailing 12-Month GAAP Operating Margin: 9.5%

Founded in 1951, Champion Homes (NYSE:SKY) is a manufacturer of modular homes and buildings in North America.

Why Does SKY Stand Out?

1. Annual revenue growth of 14.7% over the last two years was superb and indicates its market share increased during this cycle
2. Share buybacks catapulted its annual earnings per share growth to 20.4%, which outperformed its revenue gains over the last five years
3. Industry-leading 37.9% return on capital demonstrates management’s skill in finding high-return investments

Champion Homes’s stock price of $79.06 implies a valuation ratio of 23.9x forward P/E. Is now a good time to buy? See for yourself in our comprehensive research report, it’s free.
