Full Conference Call Transcript
Suresh Krishna: Thanks, Ryan. Good morning, everyone, and thank you for joining our third quarter earnings call. I'm pleased to be with you today to discuss our strong results. We delivered record quarterly revenues and exceeded earnings expectations, highlighting the strength of our model and the power of focused execution. Before discussing our results in detail, I want to take a moment to share a few reflections from my first five months with Proto Labs. Spending time in our facilities and with our customers and our partners has left me energized and confident in the opportunities ahead. We are focused on removing friction, expanding our offerings, and deepening customer relationships.
While it's still early, my short time here has strengthened my confidence that our current strategy, delivering high-quality custom parts throughout the product lifecycle, from prototyping to production, is the right one.
We are in the midst of a comprehensive strategic planning process to identify specific initiatives and projects to accelerate growth and improve our operations. We are refining the details on how to achieve full realization of our strategy, and I look forward to sharing more in 2026. Meanwhile, we are committed to delivering value with speed, clarity, and discipline, unlocking long-term growth. Together with our teams, I am focused on re-accelerating revenue growth and ultimately positioning Proto Labs for long-term shareholder value creation. Now, on to our third quarter results. Revenue grew 7.8% year-over-year to a quarterly record of $135.4 million, and we had a strong quarter of earnings that exceeded expectations.
Our teams continue to execute with speed and focus, driving strong financial results. I'd like to specially commend our U.S. go-to-market teams, whose continued commitment to customers and execution fueled another quarter of double-digit revenue growth in the U.S. Our record revenue was led by increased demand in our U.S. CNC machining and sheet metal offerings, supported by strength across several key end markets. First, in aerospace and defense, we experienced continued strong demand for mission-critical precision parts in innovative areas like drones, satellites, and space exploration. As you know by now, Proto Labs works with the most prominent, innovative, and fastest-growing companies, Amazon being one of them.
Our speed, precision, quality, and reliability allow us to be a trusted partner to Amazon in several of its critical business units, notably drones and robotics. We have also supported Blue Origin with parts for their single-launch lunar cargo lander, among other projects.
Blue Origin told us they continue to use Proto Labs' services due to our impeccable customer service and levels of detail and accountability. The second area of note for us is industrial and commercial machinery. This segment also performed well, with notable activity in robotics and semiconductors. In addition, overall, Proto Labs' CNC machining revenue was driven by very strong network-fulfilled growth. I want to acknowledge our Proto Labs Network teams for their excellent execution through periods of significant tariff uncertainty and implementation challenges. Our teams managed through uncertainty and increased demand while reducing customer friction and driving higher sequential network gross margins. These results demonstrate our ability to execute well and deliver strong performance across our target industries.
Now, shifting to our two key performance indicators where we made significant improvements.
Third quarter revenue per customer increased almost 15% year-over-year as we continue to drive increased share of wallet with our large and strategic customers. I am very encouraged by the traction we are seeing in deepening customer relationships, and I can tell you anecdotally that our large enterprise customers want to do even more with Proto Labs. Adoption of our combined offer continued to expand in this quarter, with customers utilizing both factory and network fulfillment in the last 12 months, up 35% versus the prior quarter. As we continue to serve more customers and remove customer friction, this is showing up in accelerated demand.
In fact, due to strong demand, we are expanding CNC machining capacity in our factories, a significant signal of momentum and confidence. We expect this investment to generate meaningful return. I know we can do more for our customers.
Over the past several months, we have worked to significantly expand our factory CNC machining service. You might have seen a press release announcing the launch of advanced CNC machining capabilities a few weeks ago. If you haven't, I'd encourage you to check it out. We listened to our customers and heard loud and clear that they require advanced manufacturing capabilities from Proto Labs. These capabilities include tighter tolerances for added precision, diverse finishes to strengthen and cosmetically improve parts, and fast, comprehensive quality documentation. Further, these services are all now available via our proto-labs.com e-commerce ordering platform.
This is an example of our commitment to removing friction, and we will continue to invest in improvements like this to drive demand. Moving to a broader commentary about our business, as I noted in our last earnings call, I believe we have great talent and a great culture.
I want to build on that culture by continuing to bring in and retain top talent. We are proud to be named one of America's Best-in-State Employers in 2025 by Forbes, recognizing our strong workplace culture and commitment to our employees. In addition, in early October, we announced the appointment of Mark Kermish as our Chief Technology and AI Officer. This move helps strengthen our leadership team. Mark will lead our technology teams through Proto Labs' next chapter. He brings a strong track record in digital transformation and AI strategy, and his addition underscores our commitment to these areas. We've been using AI and machine language at Proto Labs for a long time now as part of digital manufacturing.
Mark will lead our tech teams as we further embed AI and automation across our operations, driving both efficiency and better customer outcomes, both of which are central to our strategy.
We will continue to strengthen organizational capabilities to support our growth initiatives. Before passing the call over to Dan, I'd like to make some closing remarks. As I mentioned earlier, we will provide more details on strategic initiatives in 2026. Sharpening our execution and improving the customer and employee experiences are essential. Our focus is clear: accelerate profitable growth. I am very encouraged by the progress we've made over the last two quarters. We have accelerated revenue growth and exceeded expectations on earnings. We have significant momentum into year-end. I can feel it in our manufacturing facilities and in conversations with our sales teams across all of our offices.
I could not be more confident in Proto Labs' ability to execute with speed, discipline, and innovation as we deliver long-term value to our customers and shareholders. With that, I'll turn it over to Dan to walk through the financials. Dan.
Dan Schumacher: Thanks, Suresh, and good morning. I'll start with a brief overview of our third quarter results, followed by our outlook for the fourth quarter. Third quarter revenue was a company record, $135.4 million, up 7.8% year-over-year, or 6.8% in constant currencies. Revenue fulfilled through Proto Labs' network was $30.1 million, up 16.2% in constant currencies. Third quarter CNC machining revenue grew 18.2% year-over-year, or 17% in constant currencies. As Suresh stated, we're seeing very strong demand for our CNC machining services across several key end markets, most notably drones, satellites, and space exploration. In the U.S., CNC machining revenue grew 24% year-over-year.
Injection molding grew 2% year-over-year, or 1.2% in constant currencies, as we saw strong demand for network-fulfilled injection molding services offset by weak prototyping demand. 3D printing revenue declined 6.3% year-over-year, or 7.1% in constant currencies, driven by weak demand in Europe.
Sheet metal grew 13.9% year-over-year, or 13.3% in constant currencies, fueled by solid growth in most end markets. Revenue in the U.S. grew 10% year-over-year, while Europe revenue declined 5% in constant currencies. Like many manufacturers, we are seeing the effects of continued contraction in European manufacturing activity. Shifting to margins, third quarter consolidated non-GAAP gross margin was 45.9%, up 110 basis points sequentially. We delivered sequential gross margin improvements in both the factory and the network. Non-GAAP operating expenses were $48.6 million, or 35.9% of revenue, down 30 basis points from 36.2% of revenue in the second quarter, as we generated sequential efficiencies on our SG&A costs. On a year-over-year basis, SG&A was up $4.2 million.
The majority of that year-over-year increase was in variable expenses tied to revenue growth, including incentive compensation and commissions. Third quarter adjusted EBITDA was $21.1 million, or 15.6% of revenue.
Non-GAAP earnings per share were $0.47, up $0.06 sequentially. The sequential improvement was primarily driven by gross margin expansion. Compared to the third quarter of 2024, EPS was flat, as increased volume was offset by higher incentive compensation and commissions expenses. We generated $29.1 million of cash from operations during the third quarter. Proto Labs continues to lead the digital manufacturing industry in cash generation, reflecting the strength of our business model. We returned $12.8 million to shareholders in the form of repurchases. On September 30, 2025, we had $138.4 million of cash and investments on our balance sheet and zero debt. Our outlook for the fourth quarter of 2025 is outlined on slide 12.
We expect revenue between $125 million and $133 million. At the midpoint, this implies 6% revenue growth year-over-year.
Dan Schumacher: We expect foreign currency to have a $1.5 million favorable impact on revenue compared to the fourth quarter of 2024. Moving to earnings guidance, we anticipate non-GAAP add-backs in the fourth quarter to include stock-based compensation expense of approximately $3.9 million and amortization expense of $900,000. We currently estimate a non-GAAP effective tax rate between 23% and 24% in the fourth quarter. In summary, we expect fourth quarter non-GAAP earnings per share between $0.30 and $0.38. That concludes our prepared remarks. Operator, please open the line for questions.
Operator: Thank you. The floor is now open for questions. If you would like to ask a question, please press Star 1 on your telephone keypad at this time. A confirmation tone will indicate that your line is in the question queue. You may press Star 2 if you would like to remove your question from the queue. For participants using speaker equipment, it may be necessary to pick up the handset before pressing the Star keys. Again, that is Star 1 to register a question at this time. Today's first question is coming from Greg Palm of Craig Hallum. Please go ahead.
Greg Palm: Good morning. Thanks for taking the questions. Suresh, a lot of your prepared remarks revolved around this idea of accelerated growth, but I don't think a lot of investors think of Proto Labs as a growth company, just given the history over the last seven to eight years. Help us understand. What's the opportunity? What's the potential growth rate for the company longer term?
Suresh Krishna: Yeah, thanks again for that question. We are very focused on driving growth. Our last two quarters would indicate that. We've been above 7% two quarters in a row. We are working on our new strategic plan, and, as I said in my prepared remarks, will come out and share back with all of you in 2026. In the meantime, we are focused on listening to our customers, understanding our friction points, removing those friction points, and providing them what they need. We are very focused on delivering products across the entire product lifecycle. All of these are resonating with our customers.
As we focus on executing those, we will continue to evolve our strategy with our strategic plan that we will announce in 2026. The confidence we have in future growth is things we are doing right now are resonating very strongly with our customers.
Greg Palm: Is it fair to assume, are you seeing any of that right now, or are you more or less riding the wave of growth of some of your end markets like A&D? I'm just trying to get a sense of what company-specific initiatives can happen that can translate into a step up in the growth rate.
Suresh Krishna: Yeah. We shared one example of advanced machining capabilities that came directly from listening to our customers. We have a few others that we are working on that we will share more details when we come back to you in 2026. To be clear, we are seeing growth across several industries. It's not just aerospace and defense. We serve 50,000 customers a year. We are the supplier of choice for anything that has to do with innovation, and there is a lot of innovation happening across a wide variety of industries today. While we are seeing good growth in aerospace and defense, we are seeing very good growth in different industries as well.
Innovators, whether they're in their garage or they're big Fortune 500 companies, we are their destination because they want to go with speed and innovation, and we are the best partner for that. We are very diverse in our customer base.
Greg Palm: Okay. Understand. Just last one on the CNC expansion. What is the CapEx requirement associated with that? Is that just more machines? Is that a facility? Where are we in terms of that build-out right now?
Dan Schumacher: Yeah, Greg, thanks for the question. This is Dan. We're fine from a facility perspective. This is just continuing to add mills. With our digital manufacturing model, we can expand very quickly just by adding mills to the facility. I know you've been out to our Brooklyn Park facility. We can simply add mills and be able to continue industry-leading fast lead times by doing that. It's an equipment purchase.
Greg Palm: Okay. All right. Thanks for taking the questions, and best of luck.
Dan Schumacher: Thank you.
Operator: Thank you. The next question is coming from Troy Jensen of Cantor Fitzgerald. Please go ahead.
Troy Jensen: Hey, gentlemen. Congrats on the nice results.
Dan Schumacher: Thanks, Troy.
Operator: Thank you.
Troy Jensen: Hey, Suresh, for you, I know you called out record revenue per unique developer, but the unique developer number was down on a year-over-year basis. It looks like it's at least a three-year low. Can you just talk about new developers and not just growing the services you're offering? It just seems like this market, you guys should be growing unique developers and not shrinking them. Any thoughts on that, please?
Suresh Krishna: We are absolutely focused on growing our customer base. We are definitely seeing the efforts that we are putting right now is growing share of wallet, and that's what we are focused on. We are definitely looking to increase our customer base overall. When you serve 50,000 customers and our focus is right now on growing share of wallet, that's where we are seeing results. We are absolutely focused on increasing our customer base as well.
Troy Jensen: All right. Understood. Can you just talk about cross-selling? I think, Rob, you should provide us data points on % of customers that are using both factory and network.
Dan Schumacher: I think we mentioned in the script that's up 35% year-over-year of those customers that are in the trailing 12 months have ordered from both the network and the factory. The key here is what type of conversation are we having with the customer? The customer is going to upload their CAD file, and we can have a holistic discussion with them about what's important to them. Do they need fine details in terms of what their part is? Do they need it right away? Can they wait longer? What price point are they looking for?
That's really what that metric is all about, is our ability to have that broader conversation with the customer and win more business for Proto Labs.
Troy Jensen: Got it. Okay, good luck moving forward here.
Operator: Thank you.
Brian Drab: Hi. Good morning. Thanks for taking my questions. I can hear the cold in my voice as I'm starting to talk this morning. With the advanced CNC machining capability, how automated is that going to be, or how automated is it? I see that you're talking about the ability to evaluate 2D drawings. Is that type of evaluation automated? Just what were some of the challenges in bringing that additional level of service online?
Suresh Krishna: This is, as I indicated in my prepared remarks, it's tighter tolerances. It's different kinds of finishes that our customers want, and then improvements in quality documentation. We've automated all that by putting everything on our website so people can just order it on proto-labs.com as an e-commerce transaction. We've made the entire thing a digital thread. In the past, it would have been more manual, and we made it a digital thread, removing the friction for our customers.
Brian Drab: If I give you a 2D drawing that has 400 tolerances on it, is the system taking into account all 400 of those tolerances automatically, or do you have some level of manual evaluation of that by an engineer?
Suresh Krishna: The website will walk you through with drop-down menus on all the things that you want to specify. As a design engineer, you can go in and interact with the website to be able to decide what is needed, what you need, all the way into quality documentation. That way, it's all digital, and we don't need any manual intervention. We always have our application engineers available for a conversation, and many of the customers do use that. That way, if they have any clarifications, those are all sorted out. That is available for everything, whether it's for advanced or for regular. That service is available for all our customers.
Brian Drab: How are you thinking about pricing of that level of service relative to what I assume the customers could have gotten historically anyways through the Proto Labs Network? Maybe just having to wait a little bit longer. I think you have partners probably available on that network. Yeah.
Dan Schumacher: Brian, a couple of things on it. It's very automated on the front end, but if it's tripping into something that is very specific and the customer needs, we do have people that are responding to the customer and making sure that we have their parts and the parts that they need. It's a very competitive offer in the 5 to 10-day lead time space. We can do complex CNC parts very competitively from a pricing perspective in that 5 to 10-day space.
Brian Drab: Okay. Got it. Maybe just one more for now. Suresh, you've been there for five months, and you see how the CNC machining business is just booming. The injection molding business, which was obviously the legacy growth driver for many years, is still relatively flat lately. What do you think about the medium-term prospects for that business to get the growth going there again?
Suresh Krishna: Yeah. There is reduced prototyping activity in that space, which is driving some of the softness that it has been for the past few years. We are definitely focused on the three service lines and the sheet metal, which is only U.S.-based in both our geographies. As we come out and talk to you in 2026, we'll talk about more specific initiatives on what we are doing. It is, as you said, a legacy business for us, but it's a very, very good business, and we've been known for that, and we'll redouble our efforts for growth in all our service lines.
Brian Drab: Okay, thanks very much. I'll follow up more later.
Operator: Thank you. The next question is coming from James Ricchiuti of Needham & Company. Please go ahead.
James Ricchiuti: Hi. Thank you. Good morning. First, congrats on the results and the margin improvement. I was wondering, what were some of the puts and takes in the gross margin performance in the quarter? Volume, I'm sure, played a role. Did you see much improvement in the network gross margins? I don't think I heard you talk at all about tariffs, so I'm guessing that was not an issue. In general, did you break out the network gross margin?
Dan Schumacher: We did not. Network gross margins were around 33% in the quarter. Jim, you might recall from last quarter, we talked about the change in tariffs and how that negatively impacted our U.S. network margin. We give the customer a price when they order it, and we hold to that price. We could have a 30-day worth of backlog that the cost goes up on it due to pricing, and you would have a negative margin impact. We were successfully able to implement changes both to our pricing and our sourcing algorithms so that in the third quarter, even though tariff costs were still up, we were able to improve our margins quarter over quarter in the network.
There is about 80 basis points quarter over quarter that was just due to the improvement in the network margins. Outside of that, we saw improvements in our factory margin as well.
Dan Schumacher: One main driver of that is revenue in Europe was up quarter over quarter. With that increase in our Europe factory revenue quarter over quarter, we were able to operate those plants more efficiently in the third quarter. Those two things combined, both factory margins being up and network margins being up, contributed to our 110 basis point improvement second quarter to third quarter in gross margins.
James Ricchiuti: Got it. That's helpful. Thank you. When you look at the progress that you're making in the revenue per customer, that growth that you're seeing, I wonder if you could help us understand where the biggest benefits are coming from. Are they coming from—you highlighted a couple of key verticals. Obviously, there's a lot of activity in the drone space, in the robotics space. Are you seeing growth in this area just in the revenue per customer? Is it coming from the well-established Proto Labs customer that you've been working with for a long time, or is this coming perhaps from more recent customers that have just been more receptive to your production capabilities?
Just trying to understand what's driving that because it is noteworthy, I think.
Suresh Krishna: Yeah. That's a great question. We are seeing improvements from new and existing customers. We are seeing what I would say is share of wallet increase across different industries. As I said even earlier, we are a very diverse customer base. While we are seeing good strength in the sectors you mentioned within aerospace and defense, which is around drones, satellites, space, we are also seeing it in industrial areas like robotics, semiconductors, consumer electronics. We are seeing the benefits of focusing on customer voice and turning around and responding to that. That's what is helping us improve our share of wallet. Dan, you want to add anything?
Dan Schumacher: Yeah. I also would like to say we reorganized from a go-to-market perspective. At the start of the year, we talked to you guys about that. The American sales team is performing extremely well. They're having in-depth conversations with customers about what their needs are and how we can better fulfill those needs. That interaction as well is helping us to serve those customers more holistically. That is showing in that metric where how much a customer is purchasing from us is increasing.
James Ricchiuti: Got it. Thank you.
Operator: Thank you. Ladies and gentlemen, this concludes today's question and answer session and today's conference call. We would like to thank you all for your participation. You may disconnect your lines or log off the webcast at this time and enjoy the rest of your day.
