Revenue growth

Reviewing a company’s long-term revenue performance reveals insights into its quality. Any business can deliver a good quarter or two, but many enduring ones grow for years. Belden’s revenue grew at a mediocre 7.4% annualized rate over the last five years, falling short of the rest of the industrials sector, but there are still things to like about Belden.

Long-term growth is the most important, but within industrials, a half-decade historical view may miss new industry trends or demand cycles. Belden’s annualized revenue growth of 15.6% over the last two years is above its five-year trend, suggesting its demand recently accelerated.

This quarter, Belden reported year-on-year revenue growth of 38.3%, and its $966 million of revenue exceeded Wall Street’s consensus estimates by 0.5%. Company management is currently guiding for a 34.7% year-on-year increase in revenue next quarter.

Looking further ahead, sell-side analysts expect revenue to grow 24.6% over the next 12 months, according to S&P, an improvement versus the last two years. This strong growth projection suggests its newer products and services will fuel better revenue performance.

Operating margin

Operating margin is one of the best measures of profitability because it shows how much money a company earns after procuring and manufacturing its products, marketing and selling those products and, most importantly, keeping them relevant through research and development.

Belden has managed its cost base well over the last five years. It demonstrated solid profitability for an industrials business, producing an average operating margin of 11.5%. That outcome is unsurprising given its high gross margin baseline.

Analyzing the trend in its profitability, Belden’s operating margin decreased by 4.9 percentage points over the last five years. This raises questions about the company’s expense base because its revenue growth should have given it leverage on its fixed costs, resulting in better economies of scale and profitability.

In Q3, Belden generated an operating margin of 1.7%, down 9.2 percentage points year on year. The larger decline in operating margin than in gross margin suggests Belden was less efficient as 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 revenue through excessive spending on advertising and promotions.

Belden’s EPS grew at a 14.1% compounded annual growth rate over the last five years, higher than its 7.4% annualized revenue growth. However, this alone doesn’t tell us much about its business quality because its operating margin didn’t improve.

Diving into Belden’s quality of earnings can give us a better understanding of its performance. A five-year view shows that Belden has repurchased its stock, shrinking its share count by 14%. This tells us its EPS outperformed its revenue not because of increased operational efficiency but financial engineering, as buybacks boost per share earnings.

As with revenue, we analyze EPS over a shorter period to see if we are missing a change in the business.

For Belden, its two-year annual EPS growth of 19.6% was higher than its five-year trend. That acceleration is a positive sign, particularly given the already high base.

In Q3, Belden reported adjusted EPS of $2.26, up from $1.97 in the same quarter last year. This result was close to analysts’ consensus estimates. Over the next 12 months, Wall Street expects Belden’s full-year EPS to grow 14.5% from $8.45 to $9.67, according to S&P.

Key takeaways from Belden’s Q3 results

Belden’s narrow revenue beat against analysts’ consensus estimates made for a decent quarter, but investors were likely hoping for more. Shares fell 4.9% to $101.38 immediately after the release.
