Strategic Positioning

1. Siemens Partnership as Platform Multiplier

The native integration of Xometry’s AI marketplace into Siemens’ Accelerator ecosystem exposes the platform to millions of global engineers, embedding manufacturability and pricing intelligence directly into design workflows. This move dramatically expands Xometry’s reach, lowers customer acquisition costs, and sets the foundation for future large-scale enterprise partnerships. The $50 million Siemens equity investment is both a validation and a catalyst for international growth.

2. AI-Driven Product-Led Growth

Xometry’s core AI models are the engine behind its competitive moat, with recent upgrades quadrupling the training dataset and enhancing prediction accuracy for lead times, material selection, and pricing. The launch of new features like “Name Your Part” and expanded instant quoting for injection molding are reducing friction, boosting buyer retention, and driving higher conversion and margin outcomes.

3. Marketplace Network Effects and Supplier Scale

The supplier network, now at 5,000 partners across 50 countries, is a key strategic asset, enabling buyers to access certified, resilient capacity and offering Xometry sourcing flexibility. Supplier-facing tech enhancements, such as centralized communications, are deepening engagement and data capture, further strengthening the AI flywheel and margin structure.

4. Operating Leverage and International Expansion

Disciplined cost management and automation are translating growth into profitability, particularly in the U.S. where segment EBITDA margins have expanded sharply. International losses are narrowing, with management signaling further leverage as scale builds, especially as the Siemens partnership accelerates global adoption.

Key Considerations

This quarter marks an inflection point for Xometry, with the Siemens partnership and AI-driven execution accelerating both platform adoption and financial leverage. The strategic context is defined by:

Key Considerations:

  • Embedded Enterprise Access: Siemens’ global install base offers a step-function increase in buyer exposure, with direct workflow integration likely to boost active buyer counts and lower marketing costs.
  • AI Model Differentiation: Proprietary data and closed-loop learning underpin a defensible advantage in pricing, lead time, and supplier matching—key drivers of both growth and margin.
  • Supplier Network Resilience: Expansion into certified and specialized suppliers supports growth in regulated end markets and enhances platform stickiness.
  • Services Stabilization: While marketplace growth leads, services revenue remains flat, with management focused on stabilizing and eventually reaccelerating digital advertising and sourcing solutions.

Risks

Execution on large-scale integrations, such as the Siemens partnership, introduces operational complexity and timing risk, especially as global rollout ramps. International margin improvement remains unproven at scale, and services revenue is still flat, reflecting challenges in digital advertising amid broader industrial cycles. Competitive threats from legacy procurement platforms and emerging digital players persist, while macro volatility and supply chain disruptions could impact both buyer demand and supplier reliability. Guidance does not yet include Siemens upside, reflecting prudent conservatism but also leaving room for potential upward revisions—or disappointment if integration lags.

Forward Outlook

For Q2 2026, Xometry guided to:

  • Revenue of $214 to $216 million (32% to 33% YoY growth)
  • Marketplace revenue growth of approximately 35% to 36% YoY
  • Adjusted EBITDA of $11 to $12 million

For full-year 2026, management raised guidance:

  • Revenue growth of at least 27% to 28%, up from 21% previously
  • Marketplace growth of ~30%
  • Marketplace gross margins higher than 2025
  • Incremental adjusted EBITDA margins of at least 20%

Management emphasized that current guidance excludes any contribution from the Siemens partnership, and noted a strong start to Q2, with continued momentum across enterprise and product-led initiatives.

  • Siemens integration is expected to drive future upside, but is not yet in the forecast.
  • Services revenue expected to remain flat in the first half, with modest growth in the back half of the year.
