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 6^th 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.

Still, the strategy hasn’t fully proven itself yet. For the aggregates-focused approach to keep working, profitability needs to keep climbing as the newly acquired operations get folded into the business. The margin improvement seen so far is a promising start, but it doesn’t guarantee that the June 8 deal will keep paying off. What happens next depends on Vulcan successfully integrating the new Colorado and Dallas-Fort Worth operations and converting steady infrastructure demand into real profit growth. If that doesn’t happen, the case for the stock moving meaningfully higher gets weaker.

Hedge fund positioning shows a cautious signal. As per our database, 55 hedge funds held Vulcan Materials (NYSE:VMC) at the end of the first quarter, down from 68 the quarter before. That’s a fairly steep drop, and it suggests institutional investors were growing more hesitant about the stock even as its margins were improving — a sign that big money hasn’t fully bought into the turnaround story yet. For comparison, Martin Marietta Materials (NYSE:MLM) was the most popular name in the group, held by 65 hedge funds, unchanged from the prior quarter. Eagle Materials (NASDAQ:EXP) was held by 31 hedge funds, down from 45, and Knife River (NYSE:KNF) was held by 18, down from 28. So while Vulcan Materials (NYSE:VMC) still attracts more hedge fund interest than Eagle Materials (NASDAQ:EXP) or Knife River (NYSE:KNF), its decline in ownership stands out next to Martin Marietta Materials (NYSE:MLM), where institutional interest held steady.

Short interest data also paints a fairly mixed picture. About 5.85% of Vulcan Materials (NYSE:VMC) shares available for trading are currently sold short — a bet that the price will fall. That’s higher than Martin Marietta Materials (NYSE:MLM) at 4.65%, but lower than Eagle Materials (NASDAQ:EXP) at 8.29% and Knife River (NYSE:KNF) at 7.47%. In other words, some investors are skeptical of Vulcan’s turnaround story, but that skepticism is milder than what’s being directed at Eagle Materials (NASDAQ:EXP) and Knife River (NYSE:KNF).

Ultimately, the bullish case for Vulcan holds together as long as margins keep expanding, the newly acquired aggregates operations integrate smoothly, and exiting the California concrete business proves to have improved the overall quality of the company. The real test is whether Vulcan’s more focused, aggregates-driven portfolio — combined with steady infrastructure spending — can generate enough profit growth to justify Wall Street’s optimism and push the stock toward a higher valuation. Overall, hedge funds are skeptical and believe that there are better alternatives.

Previously, we covered a bullish thesis on Eagle Materials Inc. (EXP) by Margin of Sanity in May 2025, which highlighted the company’s localized market dominance, vertical integration, strong balance sheet, and disciplined capital allocation. EXP’s stock price has depreciated by approximately 11.91% since our coverage. Cameron Fen shares a similar view but emphasizes Vulcan Materials Company’s aggregates-focused transformation, expanding margins, insider buying, and infrastructure-driven upside.
