JPMorgan has upgraded Martin Marietta Materials to Overweight from Neutral, citing expected synergies from the company’s pending acquisition of Lhoist North America (LNA).
The brokerage set a $680 price target for the stock, representing a 35% premium to Tuesday’s closing price of $504.92 and implying a 2027 enterprise-value-to-EBITDA multiple of 16.0x. The stock has declined 18.6% year-to-date, underperforming peer Vulcan Materials by roughly 12% in the same period.
JPMorgan estimates the LNA deal will generate $85 million in annual cost synergies by the second year post-close, alongside $100 million to $175 million in commercial synergies. The acquisition is projected to add about 5% to Martin Marietta’s 2027 earnings per share, though these figures are not yet reflected in JPMorgan’s published estimates pending updated guidance following the third-quarter results.
The lime business will account for 23% to 25% of Martin Marietta’s total operations once the deal closes. The company secured $5.5 billion in senior unsecured notes to finance the acquisition, with all regulatory approvals in place and closing expected in the third quarter of 2026.
Martin Marietta reported adjusted earnings per share of $5.00 for the second quarter, exceeding Wall Street forecasts of $4.91, while revenue reached $1.95 billion, ahead of the $1.88 billion consensus. Separately, DA Davidson initiated coverage with a Neutral rating, while Truist Securities maintained its Buy recommendation.
