Management Comments

"I am pleased with our performance in the first quarter. We advanced our strategy of becoming a partner to building owners with mission critical building systems by accelerating our shift to ODR through acquisitions and organic growth. As a result, we are increasing Adjusted EBITDA guidance for the year," said Michael McCann, Limbach's President and Chief Executive Officer. "At the end of Q1, ODR revenue was 62.4% of total revenue, up from 55.1% at the end of Q4. With this increase in our higher margin ODR business, we are now projecting $51 million to $55 million in Adjusted EBITDA for the year compared to our previous $49 million to $53 million guidance, and our annual goal for ODR revenue as a percentage of consolidated revenue has increased from a range of 60% - 70% to a revised range of 65% - 70%. With this mix shift, we expect to see full-year Adjusted EBITDA Margin in the range of 9.6% to 10.8% for 2024 based on full-year total revenue in the range of $510 million to $530 million. Shifting our segment mix from General Contractor Relationships ("GCR") to ODR is a key pillar of our growth strategy to create a stronger, more durable Limbach, and our strategy is working.

"Gross margins and Adjusted EBITDA margins have steadily increased with the increase in ODR revenue since we began executing our strategy. As we have moved away from bigger, lower margin GCR projects, consolidated revenue has declined by design. This is an intentional sacrifice of topline growth to increase bottom line profit. Once we reach an optimized segment mix, we will expect to see the growth of the ODR business strategy reflected in topline revenue growth.

"Although the first quarter is typically the softest of the year due to weather and the seasonality of customer budgets, we are off to a strong start as business began gaining momentum in March. Our team is executing well, and their strong performance is driving the growth of the ODR business. We are adding sales resources and training as planned investments as we focus on the ODR sales model, which has been a transition for the overall business and requires more customer interaction and selling activities. These investments are paying off as we generate more frequent, more profitable transactions.

"Our strategy to grow the ODR business has plenty of runway. We strongly believe we have only scratched the surface with respect to customer relationships and market penetration. I am confident in Limbach's ability to continue to grow its ODR business, and in our team's ability to perform at a high level. We will continue to be disciplined with our engagement of new business. Our balance sheet remains strong, and we will judiciously make investments that support our strategy. Executing our strategy is how we drive higher returns and create meaningful value for our stockholders."

The following are results for the three months ended March 31, 2024 compared to the three months ended March 31, 2023:

Consolidated revenue was $119.0 million, a decrease of 1.7% from $121.0 million. ODR segment revenue of $74.3 million increased by $15.5 million, or 26.5%, while GCR revenue decreased by $17.6 million, or 28.2%. 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 ACME and Industrial Air transactions. These entities were not acquired entities of the Company for the three months ended March 31, 2023.

Total gross profit was $31.1 million, compared to $26.2 million. ODR gross profit increased $6.3 million, or 39.3%, due to the combination of an increase in revenue and higher segment margins of 29.8% versus 27.1% driven by contract mix. GCR gross profit decreased $1.4 million, or 13.5%, primarily due to lower revenue despite higher margins of 20.0%, compared with 16.6% in the prior period. The total gross profit percentage increased from 21.7% to 26.1%, mainly driven by the mix of higher margin ODR segment work, becoming more selective when pursuing GCR work, and as a result of the ACME and Industrial Air transactions.

Selling, general and administrative ("SG&A") expenses increased by approximately $1.8 million, to $22.9 million, compared to $21.1 million. The increase in SG&A expense was primarily due to approximately $1.1 million of SG&A expenses incurred within the ACME and Industrial Air entities. SG&A expense also increased due to a $0.4 million increase in professional fees, a $0.3 million increase in travel and entertainment expenses and a $0.2 million increase associated with payroll related expenses. As a percent of revenue, SG&A expenses were 19.2%, up from 17.4% in the prior period.

Interest expense was $0.5 million during the current quarter compared to $0.7 million, which was the result of a lower overall outstanding debt balance period-over-period.

Interest income was $0.6 million during the current quarter. This increase was due to the Company's investments in overnight repurchase agreements, U.S. Treasury Bills, and money market funds.

Net income was $7.6 million as compared to $3.0 million, an increase of 153.5%. A portion of the increase was attributable to a $2.0 million quarter-over-quarter income tax benefit related to the vesting of stock-based compensation awards at substantially higher market prices at each vesting date in 2024 as compared to 2023. Diluted income per share was $0.64 as compared to $0.27 in the prior period. Adjusted EBITDA was $11.8 million as compared to $8.7 million in the prior period, an increase of 35.4%.

Net cash used in operating activities of $3.9 million compared to net cash provided by operating activities of $9.4 million in the prior period.

Balance Sheet

At March 31, 2024, cash and cash equivalents were $48.2 million. Current assets were $199.4 million and current liabilities were $124.4 million at March 31, 2024, representing a current ratio of 1.60x compared to 1.50x at December 31, 2023. Working capital was $75.0 million at March 31, 2024, an increase of $3.2 million from December 31, 2023. At March 31, 2024, we had $10.0 million in borrowings against our revolving credit facility and $5.2 million for standby letters of credit.

2024 Guidance

We are updating our guidance for FY 2024 as follows:

	Current	Previous
*Revenue*	$510 million - $530 million⁽¹⁾	$510 million - $530 million
*Adjusted EBITDA*	$51 million - $55 million	$49 million - $53 million

⁽¹⁾	No change from the previous

With respect to projected 2024 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. We expect 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 and Adjusted EBITDA Margin, which are non-GAAP financial measures. 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 consolidated revenue. 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. 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 and Adjusted EBITDA Margin. Our calculation of Adjusted EBITDA and Adjusted EBITDA Margin, 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 and Adjusted EBITDA Margin cannot be achieved without incurring the costs that the measure excludes. A reconciliation of net income to Adjusted EBITDA, the most comparable GAAP measure, is 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.
