Martin Marietta's $13.5B Lhoist deal clears path as Q2 hits records
▲
Lhoist acquisition clears regulatory hurdle All regulatory approvals are now in for the $13.5 billion Lhoist North America deal, expected to close in Q3 2026. This removes a major uncertainty and should let the company become the top U.S. lime and limestone producer, boosting future earnings and margins.
This is a new, concrete step that de-risks the largest deal in company history and directly affects MLM's future earnings power.
▲
Record Q2 results and raised guidance MLM reported record Q2 revenue of $1.95 billion (up 21%) and adjusted EPS of $5.00, beating estimates. It raised full-year revenue guidance to $7.2–$7.4 billion and reaffirmed EBITDA guidance, showing strong demand for aggregates and lime.
This is fresh evidence of the company's underlying business strength and supports the bull case for the stock.
◆
Premium valuation and lowered earnings estimate Despite the earnings beat, MLM trades at 26.2 times forward earnings, above its industry average and five-year median. The consensus current-year earnings estimate has slipped 1.4% in four weeks, and Zacks rates the stock a Hold, suggesting limited upside from here.
This is the main counterweight: even with good news, the stock's high price and slightly falling profit forecasts could cap gains.

J.P. Morgan Names Reformation and Martin Marietta as Top Buys
J.P. Morgan analysts issued Buy ratings on two stocks outside the market's usual favorites, sustainable womenswear brand Reformation and construction materials supplier Martin Marietta Materials. Analyst Matthew Boss rates Reformation Overweight with a $21 price target, implying a 60% one-year gain, citing mid-to-high-teens revenue growth, a 90% direct-to-consumer revenue mix, and gross margins above 60%. Reformation, which went public on July 30 at $15 per share and raised $210.9 million in gross proceeds, reported fiscal 2Q26 revenue of $155.2 million, up 24.1% year-over-year, and EPS of $0.23, and guided full fiscal 2026 net revenue to $602 million to $606 million. Analyst Adrian Huerta rates Martin Marietta Overweight with a $680 price target, a 35% gain, after the company completed its $13.5 billion acquisition of Lhoist North America, funded with $7 billion in cash and $6.5 billion in stock. Huerta expects $85 million in cost synergies by year two and $100 million to $175 million in commercial EBITDA upside, noting the lime business will be roughly 23% to 25% of Martin Marietta's operations. Martin Marietta reported 2Q26 revenue of more than $1.9 billion, up 21% and a company record, with adjusted earnings per diluted share from continuing operations of $5.
Martin Marietta to Acquire Lhoist North America for $13.5 Billion
Martin Marietta Materials has agreed to acquire Lhoist North America in a transaction valued at approximately $13.5 billion, its largest deal to date. The consideration includes $7 billion in cash and $6.5 billion in stock, subject to customary adjustments. Lhoist North America operates 20 quarries and production facilities and 45 distribution terminals, with more than 2 billion tons of limestone reserves. On a 2026 pro forma basis including run-rate synergies and New Frontier Materials, the combined business is indicated to generate about $3.3 billion of adjusted EBITDA from continuing operations, up from roughly $2.4 billion for Martin Marietta standalone, with adjusted EBITDA margin rising to 36% from 33%. Free-cash-flow conversion is indicated at 81% for the combined company versus 76% standalone. Management expects pro forma net leverage of about 3.7 times at closing and aims to reduce it below 2.5 times within 24 months. The company ended June with $112 million of unrestricted cash and $742 million of unused borrowing capacity, and later secured a commitment for a new three-year, $1.5 billion senior unsecured term loan facility tied to the transaction. Risks include obtaining financing and regulatory approvals, integrating the businesses, realizing expected synergies, and managing dilution from newly issued shares.
Martin Marietta Q2 Earnings Beat but Premium Valuation Limits Upside
Martin Marietta Materials reported second-quarter adjusted earnings of $5.00 per share, beating the Zacks Consensus Estimate by 8.2% and rising 3.3% year over year, while revenues increased 21% to $1.95 billion. Aggregates shipments rose 17% to a record 61.6 million tons, including 2.3% organic growth, marking the fourth consecutive quarter of organic volume growth. The company raised 2026 revenue guidance to $7.2-$7.4 billion and reaffirmed adjusted EBITDA guidance of $2.36-$2.50 billion. However, the stock trades at 26.2 times forward earnings, above the sub-industry average of 20.9 times and its own five-year median of 25.8 times, and the Zacks Consensus Estimate for current-year earnings has moved 1.4% lower over the past four weeks. Zacks rates the stock a Hold, citing a neutral earnings-revision signal and weak Value, Growth, and Momentum scores.

Martin Marietta Materials Raises Revenue Guidance Despite Margin Decline
Martin Marietta Materials reported second-quarter revenue of $1.95 billion, beating analyst estimates by 6% and growing 21.1% year on year, while raising its full-year revenue guidance to $7.3 billion at the midpoint. Adjusted earnings per share came in at $5, 5.1% above consensus, but operating margin fell to 19.1% from 28.5% a year earlier, pressured by acquisition mix effects and higher energy costs. CEO Ward Nye noted that organic aggregates volumes rose for the fourth straight quarter and mix-adjusted pricing remained solid, while CFO Michael Petro said contributions from the New Frontier acquisition should largely offset elevated diesel costs. The company also highlighted the pending Lhoist North America deal, expected to diversify end markets and enhance free cash flow, and the completed rollout of new pricing technology aimed at improving future margins. Management remains cautious on near-term energy volatility but sees infrastructure and nonresidential demand, along with acquisition synergies, supporting ongoing performance.
