What the filing says
Martin Marietta entered a definitive agreement on June 27, 2026, to acquire Lhoist North America (LNA) for approximately $13.5 billion in cash and stock, expected to close H2 2026. The deal combines LNA's 20 lime/mineral quarries and 45 distribution terminals with MLM's aggregates platform. MLM also raised full-year 2026 revenue guidance to $7.2B–$7.4B (from prior range) while reaffirming Adjusted EBITDA guidance of $2.36B–$2.5B; separately identified $350M in annualized cash flow improvements from operational efficiencies and identified $200M+ cash benefits year-to-date.
Why this rating
LNA deal (~47% of MLM's $28.8B market cap) is transformational in size; however, pending close, no near-term P&L impact. Revenue guidance raise and $350M efficiency target offset execution risk and leverage increase.
