Values are as tagged by the issuer in XBRL. Revenue for banks and insurers is net of interest expense where that is the reported line. Fiscal years that do not follow the calendar are shown by their period-end date. No price, market cap, or valuation multiple is shown because Yield Theory does not republish unlicensed market data.

Diluted EPS is the earnings figure behind the price-to-earnings ratio; the P/E multiple compression calculator shows how a change in that multiple moves a share price. Shares outstanding multiplied by the share price gives market capitalization.

What investors should watch in MLM

Martin Marietta Materials, Inc. sits in Materials. Miners, chemicals, and building materials — an early-cycle, China-sensitive read on global industrial demand. We have not yet written company-specific drivers for MLM; the forces that matter most for the sector are:

  • ◆Chinese industrial and construction demand
  • ◆The US dollar and commodity prices
  • ◆Energy-transition metals like copper and lithium
  • ◆Tariffs and global trade flows

Key questions for the MLM thesis

Each question starts with what the filings show, then why it matters. None of these is a rating or a forecast.

Does MLM's reported profit turn into cash?

Operating cash flow was $1.8B, 1.57 times net income of $1.1B, for the fiscal year ended December 31, 2025.

Cash from operations exceeded reported earnings. Non-cash charges such as depreciation, amortization and stock-based compensation usually explain the gap; the cash-flow statement shows which.

How much of MLM's revenue is left as profit?

Net income was 18.5% of revenue for the fiscal year ended December 31, 2025, based on revenue and net income reported for the same period.

Net margin reflects the business model as much as execution, so compare it with companies in the same SEC industry and read the income statement for one-time items before treating it as a run rate.
