Revenue growth

A company’s long-term revenue performance can indicate its overall quality. Any business can have short-term success, but a top-tier one grows for years. MDU Resources struggled to consistently generate demand over the last five years as its revenue dropped at a 19.8% annual rate. That underwhelming result suggests it is a low-quality business.

Long-term growth matters the most, but within industrials, a half-decade historical view may miss cycles, industry trends or a company capitalizing on catalysts such as a new contract win or a successful product line. MDU Resources’s annualized revenue growth of 140% over the last two years is above its five-year trend, suggesting its demand recently accelerated.

This quarter, MDU Resources’s year-on-year revenue growth was 10.4%, and its $347.8 million of revenue was in line with Wall Street’s consensus estimates.

Looking ahead, sell-side analysts expect revenue to grow 12.5% over the next 12 months, according to S&P, a deceleration versus the last two years. Still, this projection is noteworthy and indicates the market sees success for its products and services.

Operating margin

MDU Resources has been an efficient company over the last five years. It was one of the more profitable businesses in the industrials sector, with an average operating margin of 11.9%. This result was particularly impressive given its low gross margin, which largely reflects what it sells and requires substantial shifts to change meaningfully. Companies have more control over their operating margins, and high operating margins despite low gross margins are a sign of well-managed operations.

Looking at the trend in its profitability, MDU Resources’s operating margin rose by 9.1 percentage points over the last five years, showing its efficiency has meaningfully improved.

In Q3, MDU Resources reported an operating margin of 13.7%, in line with the same quarter last year. This indicates the company’s cost structure has recently been stable.

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 revenue through excessive spending on advertising and promotions.

MDU Resources’s EPS and revenue declined by 17.2% and 19.8% annually over the last five years. Companies with falling revenue and EPS warrant caution, as diminishing earnings could imply changing secular trends and preferences. If the tide turns unexpectedly, MDU Resources’s low margin of safety could leave its stock price susceptible to large downswings.

As with revenue, examining EPS over a shorter period can reveal a change in the business.

For MDU Resources, its two-year annual EPS declines of 30.9% show it has continued to underperform. These results were poor by any measure.

In Q3, MDU Resources reported EPS of $0.07, down from $0.09 in the same quarter last year. This result missed analysts’ consensus estimates. Over the next 12 months, Wall Street expects MDU Resources’s full-year EPS to grow 9.6% from $0.93 to $1.02, according to S&P.

Key takeaways from MDU Resources’s Q3 results

MDU Resources delivered a weaker quarter, with an EPS miss and full-year EPS guidance below Wall Street’s consensus estimates. Revenue met analysts’ consensus expectations, but that was the main bright spot. Shares edged lower 1.8% to $19.47 immediately after the results.

MDU Resources underperformed this quarter, but that alone does not determine its investment appeal. What happened in the latest quarter matters, but not as much as longer-term business quality and valuation when deciding whether to invest in this stock.
