What Happened?
Shares of manufacturing services provider Proto Labs (NYSE: PRLB) fell 7% in the morning session after the company's third-quarter results and fourth-quarter guidance prompted a negative market reaction, even though quarterly revenue and earnings exceeded expectations. Management attributed the company's performance to strong demand for its U.S. CNC machining and sheet metal services. However, this momentum was tempered by persistent weakness in European manufacturing and reduced prototyping demand within the injection molding business. Looking forward, Proto Labs provided revenue guidance for the fourth quarter between $125 million and $133 million. The company also offered non-GAAP earnings per share guidance ranging from $0.30 to $0.38, which reflected cautious optimism amid market uncertainties.

What Is The Market Telling Us
Proto Labs’s shares are somewhat volatile and have had 13 moves greater than 5% over the last year. In that context, today’s move indicates the market considers this news meaningful but not something that would fundamentally change its perception of the business.
The previous big move we wrote about was 4 days ago when the stock dropped 13.8% on the news that the company's third-quarter results was overshadowed by underlying concerns about its long-term growth and profitability. The digital manufacturing services provider reported third-quarter revenue of $135.4 million, up 7.8% year on year, and an adjusted profit of $0.47 per share, both beating Wall Street estimates. Furthermore, its fourth-quarter guidance for revenue was in line with analyst expectations, and its profit forecast was slightly ahead. Despite these positive headline numbers, the initial optimism faded. Investors seemed to look past the quarterly beats and focus on weaker long-term fundamentals, including sluggish historical sales growth and a negative five-year average return on invested capital. This suggests the market believes the company has struggled to generate profitable growth, and a single strong quarter was not enough to change that perception.
Proto Labs is up 27.9% since the beginning of the year, but at $49.58 per share, it is still trading 10.3% below its 52-week high of $55.27 from October 2025. Investors who bought $1,000 worth of Proto Labs’s shares 5 years ago would now be looking at an investment worth $394.24.
