Gross margin improved 140 basis points in Q4 to 44.8%, driven by higher U.S. factory utilization, but network gross margin compressed due to tariffs and inefficiencies. Operating expenses increased on higher incentive compensation and commissions, but as a percentage of revenue, they declined slightly. Cash generation remained robust, enabling $43 million in share repurchases and a debt-free balance sheet.
- Segment Divergence: U.S. growth was offset by persistent European contraction, highlighting geographic execution gaps.
- Service Mix Shift: CNC and sheet metal outperformed, while injection molding and 3D printing lagged, except for metal additive (DMLS) strength.
- Cost Structure: Factory productivity gains lifted factory margins, but network margin erosion from tariffs and execution issues persisted.
Revenue per customer increased 13% for the year, reflecting a deliberate strategy to deepen relationships and capture greater share of wallet from existing clients. This metric, alongside record cash flow, signals improving unit economics and business resilience.

Efforts to elevate the customer experience include launching ProDesk, a new customer-facing interface designed to streamline ordering, collaboration, and support. The goal is to unify disparate storefronts, reduce friction, and drive higher conversion and retention, ultimately boosting revenue per customer and operating leverage.
4. Operational Efficiency and Global Capability Center (GCC)
Operational efficiency is being pursued through expanded productivity programs (ProtoExcellence), organizational restructuring, and the creation of a GCC in India. This hub will serve as a strategic extension for digital, engineering, and AI capabilities, supporting global innovation and delivery while tapping into India’s technical talent pool. Cost discipline and resource reallocation are prioritized to fund transformation without margin expansion in the near term.
5. European Reset and Go-to-Market Overhaul
Europe, facing two years of revenue decline, is the focus of a structural reset. Management is aligning costs to current demand, deploying new go-to-market strategies, and prioritizing productivity improvements to stabilize the region and position it for future growth.
Key Considerations
The 2026 playbook is transformational, not incremental, with leadership prioritizing foundational change over short-term margin gains. Investors should weigh the following:
- Service Mix Evolution: Growth is increasingly concentrated in U.S. CNC and sheet metal, while injection molding and 3D printing require strategic pivots toward production and metal additive, respectively.
- Revenue Per Customer Focus: The deliberate push for higher revenue per contact reflects a shift from broad customer acquisition to deepening share of wallet, which is boosting unit economics but may temporarily suppress unique developer counts.
- Tariff and Network Margin Drag: Network segment margins remain pressured by tariffs and operational inefficiencies, requiring executional discipline to restore profitability.
- Transformation Investment: Operating leverage is a long-term goal, with 2026 SG&A savings largely recycled into transformation and capability building rather than near-term profit improvement.
- European Turnaround: The success of the European reset will be critical for restoring geographic balance and unlocking latent market potential similar in size to the U.S.
