Revenue Growth Driven by Pioneer Power, but Margins Under Pressure

SG&A Growth and Operating Income Compression

Cash Flow Deterioration on Working Capital Outflows

Net cash provided by operating activities was negative $7.8 million in the first quarter of 2026, compared to positive $2.2 million in the prior-year period. The decline was driven by working capital outflows and lower net income. Capital expenditures decreased to $0.4 million from $2.2 million, resulting in negative free cash flow of $8.2 million. The company's backlog includes projects with written awards, letters of intent, or notices to proceed, and the pace of backlog conversion may be affected by macroeconomic factors.

Outlook and Risks

Management anticipates continued macroeconomic uncertainty, including inflationary pressures, supply chain disruptions, and labor shortages, which could increase costs and reduce margins. The company is focused on integrating Pioneer Power and expects gross margins to improve as the year progresses. Sales enablement initiatives are expected to support scalable, margin-accretive growth over the long term. Key risks include the pace of Pioneer Power integration, the ability to pass through cost increases to customers, and the potential for further working capital volatility on large projects.
