Management Comments

“In the first quarter, we grew revenue, gross profit, and Adjusted EBITDA, demonstrating the scalability of our business model,” Michael McCann, President and Chief Executive Officer of Limbach, said. “While the first quarter is typically our softest due to weather and customer budget seasonality, we gained significant momentum in March. Based on Q1 results, ODR now represents 67.9% of total revenue, up from 62.4% in Q1 of the previous year. We believe by expanding the ODR segment, we are substantially enhancing margins, reducing risk, and driving more predictable, reoccurring revenue. We are pleased with the additional traction we’ve gained in key end markets like healthcare as we continue to implement our growth strategy and establish Limbach as a leading building systems solutions firm that provides solutions for mission critical existing infrastructure.

“We continue to believe our strategy to grow the ODR business has significant potential. We've only begun to tap into customer relationships and market penetration. We also believe Limbach is well-positioned for continued growth in ODR, supported by strong cash generation, operational execution, and a solid M&A pipeline. Based on our current visibility, we are confident in meeting our full-year guidance and delivering long-term value for our stockholders.”

The following are results for the three months ended March 31, 2025, compared to the three months ended March 31, 2024:

•Total revenue was $133.1 million, an increase of 11.9% from $119.0 million. ODR segment revenue of $90.4 million increased by $16.1 million, or 21.7%, while General Contractor Relationships (“GCR”) segment revenue decreased by $2.0 million, or 4.5%. The increase in period-over-period ODR segment revenue was primarily due to the Company's continued focus on the accelerated growth of its ODR business and as a result of the operations of Consolidated Mechanical, LLC (“Consolidated Mechanical”). The decrease in period-over-period GCR segment revenue was primarily due to the Company’s continued focus on the execution of its mix-shift strategy to ODR, partially offset by an increase in GCR revenue associated with the operations of Kent Island Mechanical, LLC (“Kent Island”). Kent Island and Consolidated Mechanical were not acquired entities of the Company for the three months ended March 31, 2024.

•Total gross profit was $36.7 million, compared to $31.1 million. ODR gross profit increased $4.0 million, or 18.0%, due to an increase in revenue, despite slightly lower segment margins of 28.9% versus 29.8% resulting from certain ODR-related project write-ups recognized in the first quarter of 2024. GCR gross profit increased $1.6 million, or 18.3%, due to higher margins of

24.7% compared to 20.0%, despite lower revenue. The total gross profit percentage increased from 26.1% to 27.6%, mainly driven by the mix of higher margin ODR segment work and the Company continuing to be more selective when pursuing GCR segment work.

•Selling, general and administrative (“SG&A”) expenses increased by approximately $3.6 million, to $26.5 million, compared to $22.9 million. The increase in SG&A expense was primarily due to a $2.0 million increase in payroll-related expenses, a $0.5 million increase in professional services fees, a $0.4 million increase in non-cash stock-based compensation expenses and a $0.2 million increase in travel and entertainment related expenses. These variances include SG&A associated with Kent Island and Consolidated Mechanical, which were not acquired entities of the Company during the three months ended March 31, 2024. As a percentage of revenue, SG&A expenses were 19.9%, up from 19.2% in the prior period.

•Interest expense was relatively flat at $0.5 million during both quarters.

•Interest income was $0.4 million during the current quarter, compared to $0.6 million in the first quarter of 2024. This decrease was related to lower interest rates and a lower average amount of cash invested in overnight repurchase agreements and money market funds period-over-period.

•Net income was $10.2 million compared to $7.6 million, an increase of 34.6%. Diluted earnings per share was $0.85, as compared to $0.64 in the prior period.

•Adjusted EBITDA was $14.9 million as compared to $11.8 million in the prior period, an increase of 26.5%.

•Adjusted net income was $13.5 million as compared to $9.7 million, an increase of 38.9%. Adjusted diluted earnings per share were $1.12 as compared to $0.82.

•Net cash provided by operating activities of $2.2 million compared to net cash used-in operating activities of $3.9 million in the prior period primarily due to changes in working capital.

Balance Sheet

At March 31, 2025, cash and cash equivalents were $38.1 million. Current assets were $204.5 million and current liabilities were $131.7 million at March 31, 2025, representing a current ratio of 1.55x compared to 1.46x at December 31, 2024. At March 31, 2025, the Company had $10.0 million in borrowings against its revolving credit facility and $5.1 million for standby letters of credit.

2025 Guidance

The Company is affirming its previously provided guidance for 2025 as follows:


Revenue						$610 million - $630 million
Adjusted EBITDA						$78 million - $82 million

With respect to projected 2025 Adjusted EBITDA guidance and Adjusted EBITDA Margin, a quantitative reconciliation is not available without unreasonable efforts due to the high variability, complexity and low visibility with respect to certain items, which are excluded from Adjusted EBITDA. The Company expects the variability of these items to have a potentially unpredictable, and potentially significant, impact on future financial results.

Non-GAAP Financial Measures

In assessing the performance of our business, management utilizes a variety of financial and performance measures. The key measures are Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Net Income and Adjusted Diluted Earnings per Share, which are non-GAAP financial measures.

Adjusted EBITDA and Adjusted EBITDA Margin

We define Adjusted EBITDA as net income plus depreciation and amortization expense, interest expense, and taxes, as further adjusted to eliminate the impact of, when applicable, other non-cash items or expenses that are unusual or non-recurring that we believe do not reflect our core operating results. We define Adjusted EBITDA Margin as Adjusted EBITDA divided by total revenue. Our board of directors and executive management team focus on Adjusted EBITDA and Adjusted EBITDA Margin as two of our key performance and compensation measures. Adjusted EBITDA and Adjusted EBITDA Margin assists us in comparing our performance over various reporting periods on a consistent basis because it removes from our operating results the impact of certain items that do not necessarily reflect our core operations. We believe that Adjusted EBITDA and Adjusted EBITDA Margin are meaningful to our investors to enhance their understanding of our financial performance for the current period and our ability to generate cash flows from operations that are available for taxes, capital expenditures and debt service.

Adjusted Net Income and Adjusted Diluted Earnings per Share

We define Adjusted Net Income as net income, adjusted to exclude certain items that do not reflect our core operating performance, such as amortization of intangible assets, stock-based compensation, restructuring charges, the change in fair value of contingent consideration, acquisition and other transaction costs and the net tax effect of reconciling items, as further adjusted to eliminate the impact of, when applicable, other non-cash or expenses that are unusual or non-recurring. We define Adjusted Diluted Earnings per Share as Adjusted Net Income divided by the weighted average diluted shares outstanding. We believe Adjusted Net Income and Adjusted Diluted Earnings per Share are useful to investors as we use these metrics to assist with strategic decision making, forecasting future results, and evaluating current performance.

We understand that these non-GAAP financial measures are frequently used by securities analysts, investors and other interested parties as a measure of financial performance and to compare our performance with the performance of other companies that report Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Net Income and Adjusted Diluted Earnings per Share. Our calculations of these non-GAAP measures, however, may not be comparable to similarly titled measures reported by other companies. When assessing our operating performance, investors and others should not consider this data in isolation or as a substitute for net income calculated in accordance with GAAP. Further, the results presented by Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Net Income and Adjusted Diluted Earnings per Share cannot be achieved without incurring the costs that the measure excludes. A reconciliation of net income to Adjusted EBITDA and net income to Adjusted Net Income, the most comparable GAAP measures, are provided below.

We refer to our estimated revenue on uncompleted contracts, including the amount of revenue on contracts for which work has not begun, less the revenue we have recognized under such contracts, as “backlog.” Backlog includes unexercised contract options.
