FLR vs VMC: How Fluor Corporation and Vulcan Materials Compare (2026)
Last updated August 2026
Short answer
FLR and VMC are similarly sized, but FLR trades noticeably cheaper on forward earnings (15.33x vs 24.88x): the market is paying up for VMC's profile and pricing FLR more conservatively, or for faster growth. Which you prefer comes down to the drivers you believe, and whether adding either over-concentrates what you already own.
FLR vs VMC: the tie-breaker metrics
Same yardstick, side by side (as of August 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.
| Metric | FLR | VMC | What it tells you |
|---|---|---|---|
| Forward P/E | 15.33 | 24.88 | Valuation on next year's expected earnings, the same yardstick for both. Lower is cheaper for that growth; higher means the market is paying up. |
| Trailing P/E | 22.91 | 31.63 | Valuation on the last 12 months. A big drop from trailing to forward means the market expects earnings to jump, so more growth is already in the price. |
| Beta | 1.23 | 1.05 | Volatility vs the market. Above 1 swings harder than the index; below 1 is steadier. Higher beta means bigger drawdowns to hold through. |
| Price vs 52-week range | 70% of range | 21% of range | Where today's price sits between the 52-week low and high. Near the high is momentum with less margin of safety; near the low is out of favor or a discount, depending on why. |
| Price / book | 2.47 | 4.11 | How much you pay over book value. Very high can signal an asset-light, high-return business or a rich price. |
Reading it: FLR is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.
Before you buy: how FLR and VMC affect your concentration
The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. FLR and VMC share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.
This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined FLR and VMC exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

What does Fluor Corporation (FLR) do?
Fluor Corporation is one of the largest engineering, procurement, and construction (EPC) firms in the world. The company provides design and construction services for large industrial projects across energy, chemicals, mining, infrastructure, government, and increasingly clean energy and advanced manufacturing. Fluor typically operates as the lead EPC contractor on multi-billion-dollar projects, coordinating engineering, equipment procurement, and construction execution.
What does Vulcan Materials (VMC) do?
Vulcan Materials is the largest producer of construction aggregates in the United States. Aggregates (crushed stone, sand, gravel) are the fundamental inputs to concrete, asphalt, and road base used in virtually every construction project. The business is local and economic: aggregates are heavy and expensive to transport relative to their value, so each Vulcan quarry serves a relatively local market (typically 50-100 miles depending on transport mode). This creates regional pricing power.
FLR vs VMC: how do they differ?
Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.
- FLR drivers: Strategic refocus and risk discipline; NuScale Power and small modular reactors.
- VMC drivers: Federal infrastructure spending; Residential and commercial construction.
Which fits which kind of investor
A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: Large EPC projects carry execution risk that has historically been disruptive to earnings. For VMC, construction activity is cyclical.
FLR or VMC: which should you pick?
FLR vs VMC: the full fundamentals
FLR. Fluor's valuation reflects the EPC project execution risk that has historically driven earnings volatility, the NuScale Power optionality, and the LNG and energy transition project pipeline. The thin EPC margins make profit margins very sensitive to project outcomes.
VMC. Vulcan trades at one of the highest multiples in industrials reflecting the durable pricing power, the federal infrastructure tailwind, the population migration tailwind to Vulcan's geographic footprint, and the irreplaceable nature of aggregates reserves. The premium has been sustained for years.
Headline figures (approximate, early 2026): FLR shows revenue (ttm) ~$17 billion, operating margin ~4% (thin, typical EPC), net income (ttm) ~$200 million (volatile), eps (ttm) ~$1.30; VMC shows revenue (ttm) ~$8 billion, operating margin ~21%, net income (ttm) ~$1 billion, eps (ttm) ~$7.50.
The bottom line: FLR vs VMC
FLR and VMC are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme.

FAQ
What is the difference between FLR and VMC?
+
Fluor Corporation is one of the largest engineering, procurement, and construction (EPC) firms in the world. Vulcan Materials is the largest producer of construction aggregates in the United States. They show up together because they share investment themes, but they are different businesses, so the better fit depends on which thesis you are expressing.
Is FLR or VMC the better stock?
+
Neither is universally better; they suit different views and risk levels. Walnut is informational, not investment advice. Compare what each does, the tie-breaker metrics above, and the risks, then decide which fits your thesis and what you already own.
Which is cheaper, FLR or VMC?
+
On forward P/E (as of August 2026), FLR trades at 15.33x and VMC at 24.88x, so FLR is the cheaper of the two on next year's expected earnings. A lower multiple is not automatically the better buy: a richer valuation can be justified by faster growth, and a lower one can reflect real risk. Weigh the multiple against how fast each business is compounding.
Should you own both FLR and VMC?
+
Because they share themes, owning both concentrates you in that theme. That can be intentional (a focused bet) or accidental (less diversification than it looks). Walnut can show your combined exposure across both, and whether adding either over-concentrates you, before you buy.
What are the risks of FLR vs VMC?
+
FLR: Large EPC projects carry execution risk that has historically been disruptive to earnings. NuScale's commercial path is uncertain. Energy transition policy reversals or delays can affect project pipelines. VMC: Construction activity is cyclical. Energy costs (fuel for trucks and processing) affect operating margins. Reserve life requires ongoing acquisitions and permitting; new quarry permits are increasingly difficult to obtain.
