Martin Marietta Earnings: Pricing Power Continues to Drive Results Despite Mixed Construction Demand

Narrow-moat-rated Martin Marietta Materials reported solid fourth-quarter results that were largely in line with our expectations. Net sales rose 1.5% year over year as strong growth in aggregates was offset by declines in the cement business, mainly due to the impact of divestitures. Higher interest rates continue to be a challenge for Martin Marietta as residential and light commercial construction demand remains muted. That said, the company continues to benefit from infrastructure demand due to spending from the 2021 infrastructure bill as well as some other private-construction end markets, such as data centers. While risks of a prolonged downturn in residential and private construction markets remains, we expect infrastructure spending will buoy Martin Marietta's aggregate shipments in 2025. We have increased our fair value estimate to $380 per share from $370 due to the time value of money.
