Company Overview

Founded in 1981 when computer vision was in its infancy, Cognex (NASDAQ: CGNX) develops machine vision systems and software that help manufacturers and logistics companies automate quality inspection and tracking of products.

Revenue Growth

A company’s long-term performance is an indicator of its overall quality. Even a bad business can shine for one or two quarters, but a top-tier one grows for years.

With $1.05 billion in revenue over the past 12 months, Cognex 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.

As you can see below, Cognex grew its sales at a tepid 3.5% compounded annual growth rate over the last five years. This shows it failed to generate demand in any major way and is a rough starting point for our analysis.

We at StockStory place the most emphasis on long-term growth, but within business services, a half-decade historical view may miss recent innovations or disruptive industry trends. Cognex’s annualized revenue growth of 11.2% over the last two years is above its five-year trend, suggesting its demand recently accelerated.

This quarter, Cognex reported robust year-on-year revenue growth of 24.3%, and its $268.4 million of revenue topped Wall Street estimates by 9.3%. Company management is currently guiding for a 16.4% year-on-year increase in sales next quarter.

Looking further ahead, sell-side analysts expect revenue to grow 3.7% over the next 12 months, a deceleration versus the last two years. This projection doesn't excite us and implies its products and services will see some demand headwinds.

Adjusted Operating Margin

Adjusted operating margin is an important measure of profitability as it shows the portion of revenue left after accounting for all core expenses – everything from the cost of goods sold to advertising and wages. It’s also useful for comparing profitability across companies because it excludes non-recurring expenses, interest on debt, and taxes.

Cognex has been a well-oiled machine over the last five years. It demonstrated elite profitability for a business services business, boasting an average adjusted operating margin of 21.8%.

Looking at the trend in its profitability, Cognex’s adjusted operating margin decreased by 7.5 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 Q1, Cognex generated an adjusted operating margin profit margin of 26.7%, up 12.3 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.

Sadly for Cognex, its EPS declined by 2.2% annually over the last five years while its revenue grew by 3.5%. This tells us the company became less profitable on a per-share basis as it expanded due to non-fundamental factors such as interest expenses and taxes.

Diving into the nuances of Cognex’s earnings can give us a better understanding of its performance. As we mentioned earlier, Cognex’s adjusted operating margin expanded this quarter but declined by 7.5 percentage points over the last five years. This was the most relevant factor (aside from the revenue impact) behind its lower earnings; interest expenses and taxes can also affect EPS but don’t tell us as much about a company’s fundamentals.

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

For Cognex, its two-year annual EPS growth of 30.4% was higher than its five-year trend. This acceleration made it one of the faster-growing business services companies in recent history.

In Q1, Cognex reported adjusted EPS of $0.34, up from $0.16 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 Cognex’s full-year EPS of $1.19 to grow 11.5%.

Key Takeaways from Cognex’s Q1 Results

It was good to see Cognex beat analysts’ EPS expectations this quarter. We were also excited its revenue outperformed Wall Street’s estimates by a wide margin. Zooming out, we think this quarter featured some important positives. The stock traded up 3% to $65.45 immediately after reporting.

Cognex put up rock-solid earnings, but one quarter doesn’t necessarily make the stock a buy. Let’s see if this is a good investment. If you’re making that decision, you should consider the bigger picture of valuation, business qualities, as well as the latest earnings.
