Material changes versus the prior year
- Revenue rose 12.4%, including $33.3 million from Hubs. Excluding Hubs, U.S. revenue rose 6.1% and Europe was essentially flat; Japan revenue declined 4.7%.
- CNC machining revenue increased 26.8%, 3D printing 16.3%, sheet metal 8.3% and injection molding 3.7%.
- Gross margin fell 4.5 percentage points, primarily due to labor and material inflation and revenue mix. Cost of revenue grew 22.6%, faster than sales.
- Operating income declined 32.6% and net income declined 34.4%. Higher Hubs-related costs, wage and material inflation, and PL 2.0 system costs contributed.
- Operating cash flow fell by $51.7 million, including a $20.1 million increase in accounts receivable. Investing included $127.4 million of net cash used for the Hubs acquisition and $34.2 million in capital expenditures.
Outlook, commentary and risks
Management expects continued investment in technology, personnel, facilities and growth; anticipated future growth capital expenditures are approximately 8%–12% of revenue, excluding building purchases and maintenance capital. No specific revenue or earnings guidance is provided. The company expects Hubs and the PL 2.0 platform to broaden its offering and support growth, while noting that integration and execution remain important.
Risks highlighted include COVID-19 uncertainty, supply-chain constraints, labor and materials inflation, intense competition, customer demand and pricing, technology and system interruptions, cybersecurity and confidential design-data protection, foreign-exchange exposure, and acquisition integration. The Hubs contingent consideration was reversed after performance targets were not met, producing a $12.5 million operating-expense benefit; the company reported no goodwill impairment. Auditors issued unqualified opinions on the financial statements and internal controls, but Hubs—representing 7% of 2021 revenue—was excluded from the internal-control assessment.
Important facts for investors to verify
- How much of future growth and profitability depends on successfully integrating Hubs and combining its platform with Protolabs’ systems.
- Whether gross-margin pressure from labor, materials and product mix persists, and how operating costs scale with revenue.
- Collections and working-capital trends following the increase in accounts receivable and decline in operating cash flow.
- Performance of the acquired business and any further contingent consideration or acquisition-related effects.
- Exposure to currency movements, supply disruptions, and the company’s ability to protect customer design data and maintain system availability.
