Company Overview

Pioneering the concept of online quoting and manufacturing for custom prototypes and low-volume production parts, Proto Labs (NYSE:PRLB) offers injection molding, 3D printing, and sheet metal fabrication for manufacturers in various industries.

Revenue Growth

A company’s long-term performance is an indicator of its overall quality. Any business can experience short-term success, but top-performing ones enjoy sustained growth for years. Regrettably, Proto Labs’s sales grew at a sluggish 4.4% compounded annual growth rate over the last five years. This was below our standard for the industrials sector and is a poor baseline 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. Proto Labs’s annualized revenue growth of 4.9% over the last two years aligns with its five-year trend, suggesting its demand was consistently weak.

We can dig further into the company’s revenue dynamics by analyzing its three most important segments: Injection Molding , CNC Machining , and 3D Printing, which are 35.9%, 47.1%, and 13.8% of revenue. Over the last two years, Proto Labs’s Injection Molding (injection molds and parts) and CNC Machining (custom CNC-machined parts) revenues averaged year-on-year growth of 2.2% and 17.2% while its 3D Printing revenue (custom 3D-printed parts) averaged 2.3% declines.

This quarter, Proto Labs reported year-on-year revenue growth of 10.6%, and its $149.3 million of revenue exceeded Wall Street’s estimates by 3.6%. Company management is currently guiding for a 10.1% year-on-year increase in sales next quarter.

Looking further ahead, sell-side analysts expect revenue to grow 5.5% over the next 12 months, similar to its two-year rate. This projection is underwhelming and indicates its newer products and services will not accelerate its top-line performance yet.

Operating Margin

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

Proto Labs’s operating margin has been trending up over the last 12 months, leading to break even profits over the last five years. However, its large expense base and inefficient cost structure mean it still sports inadequate profitability for an industrials business. This result is surprising given its high gross margin as a starting point.

Analyzing the trend in its profitability, Proto Labs’s operating margin might have fluctuated slightly but has generally stayed the same 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.

This quarter, Proto Labs generated an operating margin profit margin of 7.6%, up 3.9 percentage points year on year. The increase was encouraging, and because its operating margin rose more than its gross margin, we can infer it was more efficient with expenses such as marketing, R&D, and administrative overhead.

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.

Proto Labs’s flat EPS over the last five years was below its 4.4% annualized revenue growth. However, its operating margin didn’t change during this time, telling us that non-fundamental factors such as interest and taxes affected its ultimate earnings.

Like with revenue, we analyze EPS over a more recent period because it can provide insight into an emerging theme or development for the business.

For Proto Labs, its two-year annual EPS growth of 8.2% was higher than its five-year trend. Accelerating earnings growth is almost always an encouraging data point.

In Q2, Proto Labs reported adjusted EPS of $0.60, up from $0.41 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 Proto Labs’s full-year EPS to stay about the same, moving from $2.05 to $2.06.

Key Takeaways from Proto Labs’s Q2 Results

We were impressed by Proto Labs’s optimistic EPS guidance for next quarter, which blew past analysts’ expectations. We were also excited its revenue outperformed Wall Street’s estimates by a wide margin. Zooming out, we think this was a solid print. The stock traded up 2.8% to $77.28 immediately following the results.

Proto Labs 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.
