Proto Labs Manufactures Solid 3D Printing Growth Amid Challenging Macroeconomic Environment

Proto Labs (NYSE: PRLB)released its fourth-quarter and full-year 2016 earnings before the market opened on Thursday. Year-over-year revenue for the quarter inched down 1.9%, while adjusted earnings per share declined 18%.

The quick-turn manufacturing service provider's performance was better than the numbers reflect, given that theslowdown in the manufacturing environment in which it operates has negatively impacted research and developmentspending in certain industries. Quarterly revenue came in at the midpoint of the company's guidance range, and adjusted EPS came in at the mid-to-high point of the range.

The market was enthused by the results, with shares closing up 12.4% on Thursday.

The relatively nascent 3D printing business continues to be the best performer in terms of revenue growth. Its results are better than the 7.6% year-over-year growth figure reflects. The 2015 fourth-quarter results included revenue from unprofitable 3D printing contracts at Alphaform (the German service bureau acquired in early October 2015) that Proto Labs terminated. Excluding these contracts, revenue from 3D printing jumped 16.6%.

Given the robust projected growth dynamics for the 3D printing industry, Proto Labs' 3D printing business has the potential to be a particularly powerful growth engine. The challenge this presents to earnings growth is that this business, at least currently, has a lower gross margin than the other services provided, as management has previously said.

  • GAAP operating margin was 20.5% compared to 22.4% in the year-ago period. Adjusted operating margin was 23.1%.

What management had to say

CEO Vicki Holt addressed the macroeconomic environment in the press release: "Our fourth quarter financial results continued to reflect the challenges that we faced throughout 2016 with general economic conditions affecting the R&D spending in certain industries, a trend that was felt with greater impact as we closed out the year."

She also outlined steps that Proto Labs took in 2016 that havestrengthened its competitive position and enhanced its ability to generate better results:

Looking ahead

CFO John Way outlined the first-quarter 2017 guidance on the conference call as follows:

Metric Q1 2017 Guidance Q1 2016 Result Expected Year-Over-Year Change
Revenue $73 million-$78 million $72.6 million flat to 7.4%
Adjusted EPS $0.42 to $0.48 $0.44 (4.5%)-9.1%

Data source: Proto Labs.

Adjusted for an expected $1.2 million negative impact from foreign currency translation and the year-ago period's approximately $1 million of revenue related to resin resale and terminated unprofitable contracts, revenue growth is expected to be in the range of 3.5% to 10%.

Holt said in the press release that Proto Labs will be focused on three priorities in 2017:

  1. "[Improving] sales and marketing productivity to bring in new product developers and generate increased revenue."
  2. Continued expansion of service offerings "to capture more of our customers' needs."
  3. Improving gross margin to 58% to 60% of revenue.

Holt said on the earnings call that plans to improve the gross margin will be focused on the European 3D printing business, which has a lower gross margin than the 3D printing business in the U.S.
