Own Caterpillar For The Boom? Federal Signal Deserves A Look

Both stocks ride the same industrial wave, but the smaller Federal Signal is sending a clearer forward signal on profits and guidance than the high-flying giant.

If you own a piece of the industrial economy, there’s a good chance you do it through Caterpillar (CAT). It’s the default way to bet on everything from construction to energy infrastructure. But in the same industry, a much smaller rival, Federal Signal (FSS), offers the same exposure. After a year where CAT’s stock has dramatically outperformed, the obvious conclusion is that the giant is the only name that matters. The forward-looking evidence, however, tells a more complicated story.

Decisions are about the future. And on that score, the company sending the cleaner, more confident signal right now isn’t the one you’d expect.

The Clearest Signal: Who Just Raised The Bar?

A company’s own forecast is its most direct statement about the future. Here, the contrast is sharp. In its latest report, Federal Signal’s management beat expectations and followed up by raising its full-year outlook. The company is now guiding for adjusted earnings per share in a new range of “$4.80 to $5.05 from the prior range of $4.50 to $4.80.” That’s a tangible increase in confidence.

Caterpillar also increased its sales outlook, now anticipating “low double-digit growth for full year 2026 sales and revenues.” But its profit outlook was more measured. Management expects its adjusted operating profit margin to remain near the bottom of the target range, partly due to the ongoing impact of tariffs, which it estimates will be in the range of “$2.2 billion to $2.4 billion” for the year. A company is raising its profit forecast; the other is raising its sales forecast while flagging persistent margin constraints.

The Demand Story: A Record Backlog Versus A Quieter One

Caterpillar’s bull case is built on a powerful and visible demand story. The company’s backlog grew to a “record level of $63 billion,” fueled by a surge in orders for large engines to power data centers. More than a cyclical bump, this appears to be a structural tailwind, with management noting that “customers are committing to longer-term orders with some orders well into 2028.” This visibility is CAT’s primary moat, justifying a massive plan to increase its large engine capacity to “nearly 3x 2024 levels.”

Federal Signal’s demand picture is solid, but less spectacular. Its backlog stands at $1.04 billion. While orders grew, management noted that after adjusting for acquisitions and other items, underlying “organic orders were flat.” This was partly due to an approximate “$20 million year-over-year reduction in international export orders.” An investor in FSS is accepting a story with less certain organic growth momentum.

Which Profit Story Is More Durable?

Looking forward, profitability is where the two stories diverge most. Federal Signal is actively raising its own performance targets. Management is “formally raising our EBITDA margin targets today for our Safety and Security Group to a new range of 22% to 28% from the previous range of 18% to 24%.” This signals a belief in durable, structural profit improvement.

Caterpillar, by contrast, is fighting battles on multiple fronts. Its Resource Industries segment saw its profit decrease by 39% in the first quarter, with the segment’s margin falling by 700 basis points. While the data center business is booming, weakness in other key areas and the significant tariff headwind create a more complex profit picture.

Trailing results confirm this forward-looking tension. Federal Signal screens as the more profitable of the two on operating margin and has grown revenue faster over both the last year and a 3-year average. Caterpillar’s massive stock run of +171.3% in the last 12 months has pushed its valuation to a price-to-operating-income multiple of 36.4, while Federal Signal trades at a more modest 20.5. You are paying a significant premium for CAT’s visible backlog, a price that doesn’t seem to fully account for its margin challenges.

The Tradeoff: Visible Growth vs. Confident Execution

On the evidence, Federal Signal currently presents a cleaner way to own this industrial exposure. Its management is sending stronger signals on future profitability, and its valuation, growth, and balance sheet metrics line up to confirm that story. It is growing faster, is more profitable at the operating level, and costs less.

The choice isn’t simple. With Caterpillar, you get exposure to a massive, multi-year backlog driven by the data center buildout, of the most powerful secular trends today. The risk is that you’re paying a premium price for a company whose profitability is being pressured by tariffs and weakness in other key segments. With Federal Signal, you get a company whose management is raising its own targets for profit and earnings, backed by stronger recent growth and a lower valuation. The risk is that its organic growth has flattened, and you need to trust that management can continue its strong execution and integration of acquisitions to keep the story going.

The decision turns on which forward risk you’d rather underwrite: Caterpillar’s execution on its massive backlog against significant margin headwinds, or Federal Signal’s ability to translate its operational discipline into renewed organic growth.

Rather Compare Them On Your Own Terms?

You can line Caterpillar and Federal Signal up directly on the Caterpillar peer comparison, weigh them on valuation, growth, margins, and returns, and swap in any other Construction Machinery & Heavy Transportation Equipment names you hold.

Asking that question of one pair is easy. Asking it of every stock you own, and re-asking it each quarter as the numbers move, is the part almost nobody keeps up with, and it is exactly where most portfolios quietly fall behind the market.
