Even though the stock has become cheaper, we're cautious about Amentum. Here are three reasons why you should be careful with AMTM and a stock we'd rather own.

Why Do We Think Amentum Will Underperform?

With operations spanning approximately 80 countries and a workforce of specialized engineers and technical experts, Amentum Holdings (NYSE:AMTM) provides advanced engineering and technology solutions to U.S. government agencies, allied governments, and commercial enterprises across defense, energy, and space sectors.

1. Long-Term Revenue Growth Disappoints

A company’s long-term sales performance can indicate its overall quality. Any business can put up a good quarter or two, but many enduring ones grow for years. Regrettably, Amentum’s sales grew at a tepid 4% compounded annual growth rate over the last two years. This was below our standard for the business services sector.

2. Projected Revenue Growth Is Slim

Forecasted revenues by Wall Street analysts signal a company’s potential. Predictions may not always be accurate, but accelerating growth typically boosts valuation multiples and stock prices while slowing growth does the opposite.

Over the next 12 months, sell-side analysts expect Amentum’s revenue to rise by 1.6%, a slight deceleration versus its 4% annualized growth for the past two years. This projection is underwhelming and indicates its products and services will see some demand headwinds.

3. Mediocre Free Cash Flow Margin Limits Reinvestment Potential

If you’ve followed StockStory for a while, you know we emphasize free cash flow. Why, you ask? We believe that in the end, cash is king, and you can’t use accounting profits to pay the bills.

Amentum has shown poor cash profitability over the last three years, giving the company limited opportunities to return capital to shareholders. Its free cash flow margin averaged 1.8%, lousy for a business services business.

Final Judgment

Amentum falls short of our quality standards. Following the recent decline, the stock trades at 9.2× forward price-to-earnings (or $19.75 per share). While this valuation is optically cheap, the potential downside is huge given its shaky fundamentals. There are better investments elsewhere.
