Management Comments

“We are pleased to report a solid third quarter, underscoring the success of our strategic transition to higher margin ODR business,” said Michael McCann, President and Chief Executive Officer of Limbach. “ODR revenue increased 52.0% year-over-year and now represents about 76.6% of total revenue for the quarter, in line with our annual mix shift guidance of 70% to 80%. We also expect ODR organic revenue growth to be in the range of 20% to 25% for the full year and maintain strong gross margins. Total ODR gross profit rose $6.0 million accounting for approximately 80% of total gross profit. These results demonstrate the tangible impact of our strategic focus to drive growth in our ODR business, minimize risk, and improve the consistency of our revenue and earnings.

“Limbach is delivering against all three core elements of our growth strategy, leveraging disciplined M&A to accelerate scale and reinforce long-term growth. In the third quarter, we completed the acquisition of Pioneer Power, expanding our footprint into the Upper Midwest, and deepening our access to industrial markets including power generation. Pioneer Power’s revenue performance exceeded our initial expectations this quarter. While Pioneer Power’s current margin profile differs from Limbach’s, we are actively integrating Pioneer into the Limbach platform and have a path to implement operational and commercial enhancements that we expect will expand its margins over time. Combined with our focus on expanding our top-line through our ODR business, broadening our service offerings, and deepening customer relationships, we are building a resilient business designed to deliver durable long-term value for our stockholders.”

The following are results for the three months ended September 30, 2025, compared to the three months ended September 30, 2024:

• Total revenue increased 37.8%, or $50.7 million, to $184.6 million from $133.9 million. The increase in revenue was primarily attributable to the acquisitions of Pioneer Power, Consolidated Mechanical, LLC (“Consolidated Mechanical”) and Kent Island Mechanical, LLC (“Kent Island”). Of the total increase in revenue, acquisition related revenue represented 35.3%, or $47.3 million, and organic represented 2.5%, or $3.3 million.

• ODR segment revenue increased 52.0%, or $48.4 million, to $141.4 million. Acquisition-related revenue represented 39.8% or $37.1 million, while organic revenue represented 12.2%, or $11.3 million period-over-period.
• General Contractor Relationships (“GCR”) segment revenue increased 5.6%, or $2.3 million, to $43.2 million. Acquisition-related revenue represented 25.1%, or $10.3 million, while organic revenue represented a 19.5%, or $8.0 million decrease period-over-period as the Company continues its strategic mix-shift to ODR.

• Total gross profit increased 23.7% to $44.7 million compared to $36.1 million. Total gross margin of 24.2% decreased from 27.0% in the third quarter of 2024.

• ODR gross profit increased 20.3%, or $6.0 million, to $35.7 million from $29.6 million while gross margins decreased to 25.2% from 31.9% primarily due to the impact of Pioneer Power which has a lower gross margin profile compared to Limbach’s historical profile. Management is focused on improving Pioneer Power’s gross margins to align with the Company’s broader operating model over time.
• GCR gross profit increased 39.3%, or $2.5 million, to $9.0 million from $6.5 million and gross margins increased to 20.8% from 15.8% driven by the Company’s selective focus on higher quality projects.

• Selling, general and administrative (“SG&A”) expense increased by approximately $4.6 million to $28.3 million, compared to $23.7 million in the prior year period. SG&A expense increased primarily due to a $2.3 million increase in payroll related expense, a $1.5 million aggregate increase in SG&A expense associated with Pioneer Power and Consolidated Mechanical, and a $0.4 million increase in non-cash stock-based compensation expense. Pioneer Power and Consolidated Mechanical were not acquired entities during the same period in 2024. SG&A expense as a percentage of revenue decreased to 15.3% as compared to 17.7% primarily due to the increased revenue in the third quarter of 2025 as a result of the Pioneer Power acquisition.
• Interest expense was $1.2 million, an increase of $0.8 million, compared to $0.5 million in the prior year period. The increase in interest expense was driven by increased borrowings under the Company’s revolving credit facility and higher financing costs associated with a larger vehicle fleet.
• Interest income was $0.1 million, a decrease of $0.5 million, compared to $0.6 million in the third quarter of 2024. This decrease was related to reduced cash and cash equivalent balances and lower yields on investments.
• Net income increased 17.4% to $8.8 million from $7.5 million. Diluted earnings per share was $0.73 compared to $0.62 in the prior year period.
• Adjusted EBITDA increased 25.6% to $21.8 million compared to $17.3 million in the prior year period.
• Adjusted net income increased 16.4% to $12.7 million compared to $10.9 million. Adjusted diluted earnings per share was $1.05 compared to $0.91 in the prior period.
• Net cash from operating activities was $13.3 million compared to $4.9 million reflecting the timing of billings that impacted changes in working capital.

Balance Sheet

At September 30, 2025, cash and cash equivalents were $9.8 million. Current assets were $216.8 million and current liabilities were $151.2 million, representing a current ratio of 1.43x compared to 1.46x at December 31, 2024. At September 30, 2025, the Company had $34.5 million in borrowings under its revolving credit facility and $5.1 million of standby letters of credit. The Company intends to deploy free cash flow to continue to reduce its borrowings under its revolving credit facility for the remainder of the year.

2025 Guidance

The Company is reaffirming its previous guidance for FY 2025 as follows:

With respect to projected 2025 Adjusted EBITDA guidance and Adjusted EBITDA Margin (and the assumptions underlying those projections), 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 (and components that go into the calculation of Adjusted EBITDA). The Company expects the variability of these items to have a potentially unpredictable, and potentially significant, impact on future financial results. During the period, the Company refined certain underlying assumptions used to model its 2025 guidance to better reflect current market conditions, project timing, and operational performance trends. These updates influence the Company’s outlook and are incorporated into the Company’s publicly issued guidance ranges for total revenue and Adjusted EBITDA.

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.

Supplemental Revenue Disclosures

Organic and acquisition-related revenue are not defined under GAAP and may not be comparable to similarly-titled measures used by other companies and should not be considered a substitute for revenue as determined in accordance with GAAP. Management believes these non-GAAP measures provide useful information to investors by highlighting the underlying growth trends of the Company’s existing operations, separate from the effects of recent acquisitions. Organic revenue growth reflects the change in revenue from the Company’s continuing operations excluding the impact of acquisitions, while acquisition-related revenue represents the incremental contribution from businesses acquired during the twelve month period following the date of acquisition. These measures are intended to enhance investors’ understanding of the Company’s performance and trends over time, and should be considered in conjunction with, but not as a substitute for, GAAP revenue.

The following are reconciliations of reported revenue to organic / acquisition-related revenue for the three and nine months ended September 30, 2025, compared to revenue for the three and nine months ended September 30, 2024:
