Vulcan Materials (VMC) vs. MLM and EXP: Can Its Aggregates Shift Keep Lifting Margins?

Is VMC a good stock to buy? We came across a bullish thesis on Vulcan Materials Company on Contrarian Indicator's Substack by Cameron Fen. In this article, we will summarize the bulls' thesis on VMC. Vulcan Materials Company's share was trading at $281.63 as of August 6th 2026. VMC's trailing and forward P/E were 33.62 and 30.96 respectively according to Yahoo Finance.

Vulcan Materials is one of the largest companies that mines and sells construction materials like crushed stone, sand, and gravel — collectively known as "aggregates." The story behind the stock right now is about simplification: management is reshaping the company to focus more on its higher-margin aggregates business. On June 8, Vulcan sold its lower-margin ready-mixed concrete operations in California and used that move to pick up aggregates businesses in southern Colorado and the Dallas-Fort Worth area from Brannan Sand & Gravel.

The company's first-quarter 2026 revenue came in at $1.80 billion, beating the $1.75 billion Wall Street expected, and its gross margin — a measure of how much profit it keeps after production costs — rose to 27.6%, up nine-tenths of a percentage point from a year earlier. That improvement happened even before the June 8 deal, which is an encouraging sign. The big question now is whether this shift toward aggregates can keep boosting profits enough to push the stock higher.

The optimistic case is fairly straightforward: Vulcan is trading a weaker part of its business for a stronger one. Ready-mixed concrete typically earns thinner profits, while aggregates tend to be more lucrative, so shifting the mix in that direction should, in theory, lift overall profitability over time. The results so far back this up, with margins already improving before the latest deal closed.

This latest deal fits that same playbook — sell the lower-margin piece, buy more of the higher-margin one. If the newly acquired Colorado and Dallas-Fort Worth operations turn out to be more profitable than the California business Vulcan gave up, that could mean further margin gains ahead, even without much revenue growth. A steady flow of infrastructure spending in the broader economy should also help keep demand for aggregates strong while management works on improving profitability. Adding to the positive picture, four of Vulcan's independent board members — Kathleen Quirk, Lydia Kennard, James Prokopanko, and David Steiner — bought shares themselves in early May at around $283.72, a sign they're confident in the company's direction near current price levels.

Wall Street analysts, on average, have set a price target of about $327 for Vulcan. That gap suggests analysts think the stock deserves a moderately higher valuation if the aggregates strategy keeps delivering, without needing anything dramatic to happen. Not everyone is fully on board, though: Royal Bank of Canada started covering the stock in late May with a more neutral "Market Perform" rating, offering a more cautious counterpoint to the broader bullish consensus. Investors will want to watch whether margins keep expanding and the new acquisitions perform well enough to justify that higher price target.
