The reporting period reflects a strategic shift following several divestitures in 2025, with results from infrastructure distribution, hydraulic fracturing equipment, and engineering businesses classified as discontinued operations.
Key Financial Metrics
| Metric | Q1 2026 | Q1 2025 |
|---|---|---|
| Total Revenue | $22.0 million | $11.6 million |
| Net Income (Loss) | $5.2 million | $(0.5) million |
| Net Income from Continuing Ops | $4.7 million | $(2.2) million |
| Adjusted EBITDA (Continuing Ops) | $1.9 million | $(2.3) million |

Margins: Gross margin for continuing operations was approximately 25% (Revenue $22.0M vs. Cost of Revenue $16.5M). The effective tax rate for continuing operations was 23.7%.
Material Changes vs. Prior Period
- Revenue Growth: Total revenue increased 90% year-over-year, driven primarily by a 584% surge in Rental Services and Aviation Sales ($13.0M vs. $1.9M) due to a $6.5M aviation equipment sale and higher utilization. Accommodation and Drilling services also saw significant revenue increases (67% and 600%, respectively).
- Profitability Turnaround: The Company reported a net income of $5.2 million compared to a net loss of $0.5 million in Q1 2025. This turnaround was significantly aided by a $7.1 million unrealized gain on marketable securities, which did not exist in the prior year.
- Segment Performance: While Rental and Accommodation segments improved, Natural Sand Proppant revenue declined 42% due to lower volume and price per ton. Infrastructure services revenue decreased 57% due to reduced fiber optic activity.
- Cash Flow: Operating cash flow from continuing operations turned negative ($2.8M outflow) compared to a smaller outflow in the prior year, primarily due to a decline in accounts receivable collections. Investing activities consumed $10.3 million, largely for aviation fleet expansion and marketable securities purchases.
Guidance, Outlook, and Risks
- Outlook: Management expects to generate positive Adjusted EBITDA from continuing operations for the full year 2026. Capital expenditures for 2026 (excluding aviation) are estimated at approximately $23.0 million.
- PREPA Settlement: A significant contingency remains regarding the Puerto Rico Electric Power Authority (PREPA). As of March 31, 2026, PREPA owes the Company $20.0 million, payable upon the effective date of PREPA's bankruptcy plan adjustment. The Company has recorded a $170.7 million allowance for expected credit losses related to this settlement.
- Litigation: The Company is defending against multiple lawsuits in Puerto Rico regarding construction excise and volume of business taxes, with judgments totaling over $10 million in 2025. The outcome remains uncertain, and the Company is unable to predict the material impact.
- Debt Facility Update: Subsequent to the quarter end (May 8, 2026), the Company reduced its revolving credit facility maximum availability from $50.0 million to $25.0 million.
Investor Verification Checklist
- Unrealized Gains: Verify the sustainability of the $7.1 million unrealized gain on marketable securities, which was a primary driver of Q1 2026 net income.
- PREPA Receivables: Monitor the status of PREPA's bankruptcy plan adjustment to assess the collectability of the remaining $20.0 million receivable.
- Aviation Sales: Confirm whether the $6.5M aviation equipment sale in Q1 2026 represents a recurring revenue stream or a one-time asset liquidation.
- Credit Facility Reduction: Review the implications of the May 2026 reduction in the revolving credit facility from $50M to $25M on future liquidity and capital expenditure flexibility.
- Operating Cash Flow: Analyze the trend in accounts receivable collections, which contributed to negative operating cash flow despite positive net income.
