Protolabs’ Production Push Tests Its New Operations Chief

A new operations chief is stepping into Protolabs as the company tries to turn its quick-turn manufacturing business into a broader production partner. Sam Ramahi, who took the chief operations officer role on August 31, now oversees global operations, supply chain, quality, sourcing and continuous improvement. CEO Suresh Krishna will retain ultimate oversight of operations, the company said.

The timing follows a strong second quarter. Revenue rose 10.6% year over year to a record $149.3 million in the quarter ended June 30. CNC machining grew 13.6%, injection molding 13.1%, and GAAP gross margin widened to 46.4% from 44.3% a year earlier. Protolabs also raised its 2026 revenue-growth forecast to 8% to 10%, from 6% to 8%.

The harder test is whether that growth can be repeated as customers move beyond prototypes and small batches. Protolabs’ model combines its own factories with Protolabs Network, a roster of manufacturing partners that extends the company’s capacity and range of processes. That gives customers more options, but it also means execution depends on coordinating quality, delivery and cost across different production sources. The company’s annual filing describes the network as a way to add capacity and specialized processes without the investment required to expand its own factories.

Ramahi brings experience suited to that task. At SIG Group, he led 1,300 employees across five facilities supporting $700 million in annual revenue; Protolabs said he improved delivery performance and inventory management there. Whether those gains translate to Protolabs is not yet established. The appointment is a bet on operational discipline, not proof of it.

Investors will also want to distinguish reported results from adjusted ones. Second-quarter GAAP operating margin was 7.6%, while the company’s non-GAAP figure was 12%. Protolabs reported $15.4 million in operating cash flow and $162.9 million in cash and investments at quarter-end. Those figures leave room to pursue growth, while making cash generation and the margin gap useful measures of whether expansion is paying off. The next quarters will show whether production work adds durable scale, or strains the speed and consistency that made Protolabs useful to customers in the first place.
