Revenue Growth

A company’s long-term sales performance is one signal of its overall quality. Any business can have short-term success, but a top-tier one grows for years.

With $192 million in revenue over the past 12 months, Napco is a small player in the business services space, which sometimes brings disadvantages compared to larger competitors benefiting from economies of scale and numerous distribution channels. On the bright side, it can grow faster because it has more room to expand.

As you can see below, Napco grew its sales at an exceptional 14% compounded annual growth rate over the last five years. This is a great starting point for our analysis because it shows Napco’s demand was higher than many business services companies.

Long-term growth is the most important, but within business services, a half-decade historical view may miss new innovations or demand cycles. Napco’s recent performance shows its demand has slowed significantly as its annualized revenue growth of 4% over the last two years was well below its five-year trend.

This quarter, Napco reported year-on-year revenue growth of 12.2%, and its $48.17 million of revenue exceeded Wall Street’s estimates by 0.7%.

Looking ahead, sell-side analysts expect revenue to grow 9.6% over the next 12 months, an improvement versus the last two years. This projection is noteworthy and suggests its newer products and services will fuel better top-line performance.

Looking at the trend in its profitability, Napco’s operating margin rose by 14 percentage points over the last five years, as its sales growth gave it immense operating leverage.

This quarter, Napco generated an operating margin profit margin of 30.6%, up 4.6 percentage points year on year. This increase was a welcome development and shows it was more efficient.

Earnings Per Share

We track the long-term change in earnings per share (EPS) for the same reason as long-term revenue growth. Compared to revenue, however, EPS highlights whether a company’s growth is profitable.

Napco’s EPS grew at an astounding 46.1% compounded annual growth rate over the last five years, higher than its 14% annualized revenue growth. This tells us the company became more profitable on a per-share basis as it expanded.

Diving into the nuances of Napco’s earnings can give us a better understanding of its performance. As we mentioned earlier, Napco’s operating margin expanded by 14 percentage points over the last five years. On top of that, its share count shrank by 2.4%. These are positive signs for shareholders because improving profitability and share buybacks turbocharge EPS growth relative to revenue growth.

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

For Napco, its two-year annual EPS growth of 5.7% was lower than its five-year trend. This wasn’t great, but at least the company was successful in other measures of financial health.

In Q4, Napco reported EPS of $0.38, up from $0.28 in the same quarter last year. This print easily cleared analysts’ estimates, and shareholders should be content with the results. Over the next 12 months, Wall Street expects Napco’s full-year EPS of $1.33 to grow 9%.
