Revenue Growth
Examining a company’s long-term performance can provide clues about its quality. Any business can experience short-term success, but top-performing ones enjoy sustained growth for years. Regrettably, Martin Marietta Materials’s sales grew at a mediocre 6.6% compounded annual growth rate over the last five years. This was below our standard for the industrials sector and is a tough starting point for our analysis.
Long-term growth is the most important, but within industrials, a half-decade historical view may miss new industry trends or demand cycles. Martin Marietta Materials’s recent performance shows its demand has slowed as its revenue was flat over the last two years. 
This quarter, Martin Marietta Materials reported robust year-on-year revenue growth of 21.1%, and its $1.95 billion of revenue topped Wall Street estimates by 6%.
Looking ahead, sell-side analysts expect revenue to grow 9% over the next 12 months, an improvement versus the last two years. This projection is admirable and indicates its newer products and services will fuel better top-line performance.

Operating Margin
Martin Marietta Materials has been a well-oiled machine over the last five years. It demonstrated elite profitability for an industrials business, boasting an average operating margin of 21%. This result was particularly impressive because of its low gross margin, which is mostly a factor of what it sells and takes huge shifts to move meaningfully. Companies have more control over their operating margins, and it’s a show of well-managed operations if they’re high when gross margins are low.
Looking at the trend in its profitability, Martin Marietta Materials’s operating margin rose by 2 percentage points over the last five years, as its sales growth gave it operating leverage.
This quarter, Martin Marietta Materials generated an operating margin profit margin of 19.1%, down 9.4 percentage points year on year. Since Martin Marietta Materials’s operating margin decreased more than its gross margin, we can assume it was less efficient because expenses such as marketing, R&D, and administrative overhead increased.
Earnings Per Share
Revenue trends explain a company’s historical growth, but the long-term change in earnings per share (EPS) points to the profitability of that growth — for example, a company could inflate its sales through excessive spending on advertising and promotions.
