Management Commentary

Limbach’s President and CEO Mike McCann emphasized the significance of the company’s strong bookings as a leading indicator of future demand and revenue growth. The company’s momentum is particularly strong in the mission-critical and data center end markets, with the latter accounting for over a quarter of bookings this quarter. Management pointed to longstanding relationships with hyperscale and mission-critical customers as a foundation for continued growth in these verticals.

However, margins were pressured this quarter due to lower fixed cost absorption, the lack of prior-year project write-ups, and the inclusion of Pioneer Power, which carries a lower margin profile. Management has already initiated targeted pricing, operational, integration, and sales actions expected to restore and expand margins as the year progresses.

The company is focused on three main strategic priorities for 2026:

1. Driving organic ODR revenue growth
2. Expanding margins by delivering higher-value solutions
3. Disciplined capital allocation, including acquisitions

Acquisition Impact: Pioneer Power

Pioneer Power, acquired in July 2025, contributed a full quarter of revenue, accounting for a significant portion of the year-over-year revenue increase. Of the \$5.8 million overall revenue gain, \$23.5 million was acquisition-related, while organic revenue declined by \$17.8 million (13.4%), reflecting lower mid-2025 bookings and normal seasonality in the industrial segment. Management expects the improved recent bookings will drive organic revenue growth as 2026 progresses.

Integration of Pioneer Power is ongoing, and management expects gross margins at Pioneer Power to improve over 2026 and reach company averages within two to three years.

Segment Performance

• ODR Segment: Revenue increased 10.4% (\$9.4 million), with acquisition-related growth of 15.8% (\$14.3 million) offsetting an organic decline of 5.4% (\$4.9 million).
• GCR Segment: Revenue decreased 8.6% (\$3.7 million), as organic revenue fell 30.2% (\$12.9 million) and acquisition-related revenue grew 21.6% (\$9.2 million).

Profitability and Cost Trends

• Gross Profit: Down 15.1% to \$31.2 million, with gross margin dropping to 22.4%.
• SG&A Expenses: Increased by \$1.6 million to \$28.1 million (20.2% of revenue), mainly due to higher payroll and Pioneer Power integration costs.
• Interest Expense: Rose to \$0.7 million from \$0.5 million, reflecting higher borrowings and fleet financing costs.
• Interest Income: Decreased to less than \$0.1 million (from \$0.4 million), due to lower cash balances and yields.

Balance Sheet and Liquidity

• Cash & Cash Equivalents: \$15.8 million as of March 31, 2026.
• Current Assets: \$191.8 million; Current Liabilities: \$112.4 million; Current Ratio: 1.71x.
• Outstanding Borrowings: \$51.7 million in long-term debt, \$7.0 million in standby letters of credit; company plans to use free cash flow to reduce borrowings.

2026 Guidance Reaffirmed

• Revenue: \$730 million – \$760 million
• Adjusted EBITDA: \$90 million – \$94 million
• Total Organic Revenue Growth: 4–8%
• ODR Revenue as % of Total Revenue: 75–80%
• ODR Organic Revenue Growth: 9–12%
• Gross Margin: 26–27%
• SG&A as % of Revenue: 15–17%
• Free Cash Flow: Targeting 75% of Adjusted EBITDA

Management highlighted that the robust bookings, especially in mission-critical sectors like data centers, support confidence in meeting full-year guidance despite Q1 margin pressures.

Non-GAAP Financial Measures

Limbach uses Adjusted EBITDA, Adjusted Net Income, and related metrics to provide greater insight into core operating performance. Adjusted EBITDA in Q1 2026 was \$8.7 million (margin of 6.2%), down from \$14.9 million (margin of 11.2%) in Q1 2025. Adjusted Net Income was \$7.8 million (\$0.64 per diluted share), down from \$13.5 million (\$1.12 per share).

Potential Share Price Sensitivities and Investor Considerations

• Strong Bookings: The exceptionally high book-to-bill ratio and continued momentum in mission-critical markets, particularly data centers, could signal future revenue acceleration and may be viewed positively by the market.
• Margin Compression: Significant declines in gross and operating margins, as well as Adjusted EBITDA, may raise concerns about profitability, especially if integration of acquisitions like Pioneer Power does not deliver anticipated margin improvements.
• Organic Revenue Decline and Acquisition Reliance: The revenue growth was driven by acquisitions, while organic revenue declined. Sustained organic growth will be important for future share price performance.
• Cash Flow Usage: The shift to net cash used in operations (vs. generation last year) reflects working capital needs and acquisition-related outflows, which may impact liquidity perceptions.
• Guidance Reaffirmation: The reiteration of full-year guidance despite Q1 challenges signals management’s confidence, but investors should closely monitor margin improvement through the year.

Conference Call Details

Limbach will host a conference call on Wednesday, May 6, 2026, at 9:00 a.m. Eastern Time to discuss these results. Dial-in and webcast links are available on the company’s investor relations website.
