Martin Marietta's $12.9B Lhoist deal cuts pro forma 2025 EPS to $14.17
What's the deal? Martin MariettaDealroom has a profile for this one. Try Dealroom → Materials has disclosed that its $12.9 billion acquisition of Lhoist North America would have diluted 2025 earnings per share to $14.17 from $16.37 on a historical basis, according to an 8-K/A filed with the US Securities and Exchange Commission. The deal, which closed on August 21, combines Martin Marietta's construction aggregates business with Lhoist's lime operations, pushing the company into steel, environmental, and industrial markets.
The terms: Consideration was $7.028 billion in cash and 10,953,543 newly issued shares valued at $5.859 billion. To fund the cash portion, Martin Marietta issued $5.5 billion of senior notes across five tranches, took on a $1.5 billion term loan, and tapped its revolving credit facility.
Why the dilution? Pro forma 2025 revenue would have risen to $7.9 billion from $6.15 billion, and net earnings from continuing operations to $1.012 billion from $990 million. But the larger share count and heavier debt dragged on per-share results; pro forma interest expense would have more than doubled to $615 million from $230 million.
What the latest quarter shows: Third-quarter revenue rose 28% to $2.37 billion, beating the $2.31 billion consensus and prompting Martin Marietta to raise its full-year revenue outlook to between $7.75 billion and $7.85 billion. Adjusted EPS of $5.47 missed the $5.71 estimate, hit by $138 million in quarterly interest expense — more than double the prior year's $59 million.
What could go wrong? Acquired Lhoist assets carry lower selling prices than the legacy business, pushing reported aggregates average selling price down 3.6% in the quarter. The key question is whether those assets can ramp toward Martin Marietta's pricing quickly enough to service the $398 million to $408 million in net interest expense now embedded in the full-year outlook.
What's next? Management guided for mid- to high-single-digit mix-adjusted aggregates pricing in 2027 and cited infrastructure and data center construction as tailwinds. January 1 pricing actions are designed to restore a positive price-cost relationship next year. The pro forma figures exclude anticipated synergies, so the company cautioned they are not indicative of future results.
The signal: The deal reflects a consolidation push in US building materials, following CRHDealroom has a profile for this one.
