Consolidated Revenue of $129.2 million

Revenue from Owner Direct Relationships Segment (ODR) up 17.6% for the year-over-year quarter

ODR Segment Accounted for Approximately 48% of Consolidated Gross Profit

Gross Margins Improved to 18.9%; Diluted EPS of $0.38

Conference Call Scheduled for 9:00 am ET on November 11, 2021

Limbach Holdings, Inc. (NASDAQ:LMB) today announced its financial results for the quarter ended September 30, 2021. Consolidated revenue improved to $129.2 million, or 6.7%, compared with the second quarter of 2021 as business conditions strengthened relative to the second quarter of 2021. ODR⁽¹⁾ segment revenue accounted for 30.4% of consolidated revenue in the third quarter of 2021 compared to 20.4% in the third quarter of 2020. Consolidated gross margin of 18.9% increased 350 basis points sequentially over the second quarter of 2021, and 410 basis points year-over-year for the third quarter as a result of a shift in mix to the ODR segment, which provides for higher gross margins, as well as better overall execution. In the third quarter of 2021, the ODR segment accounted for approximately 48% of consolidated gross profit.

Charlie Bacon, Limbach's President and Chief Executive Officer, said, "We had a strong quarter and I want to thank everyone from our office personnel to our field talent for all of their hard work. Although the year started off slowly, we have consistently maintained our view that business would meaningfully accelerate in the second half of the year and our third quarter results bear that out. Our ODR segment continues to shine, with our maintenance base hitting its highest level in company history and continuing growth in smaller dollar projects."

Mr. Bacon continued, "Sales booking activity continued to be strong during the third quarter, with activity accelerating in September, particularly in our higher margin ODR segment. At this time, we have contracts in hand that would satisfy our revenue guidance for the full year 2021 and are focused on the execution of that work and securing work for 2022 and beyond. We continue to be selective in our bidding, maintaining the same gating criteria that drove our third quarter results."

Mr. Bacon concluded, "We are affirming our Adjusted EBITDA guidance for the year to be in a range from $23 million to $25 million. However, I am disappointed with the continuing supply chain disruptions and as a result we currently believe those disruptions will drive us to track to the bottom end of this range. As many of our peers have noted, labor, materials, and equipment constitute the primary headwinds facing our industry and we echo this sentiment. We are also very mindful of our office and field labor and the current environment with respect to COVID-19. Despite these headwinds, we expect our risk management processes to deliver improved project and service execution."

⁽¹⁾As of January 1, 2021, Limbach renamed its existing two reportable segments to reflect our two distinct approaches to our customer base and to better align with our owner direct strategy. The previously named Construction Segment is now known as General Contractor Relationships ("GCR") and the previously named Service Segment is now known as Owner Direct Relationships ("ODR").

The following are results for the three months ended September 30, 2021 compared to the three months ended September 30, 2020:

Consolidated revenue was $129.2 million, a decrease of 21.2% from $163.9 million. GCR segment revenue of $90.0 million was down 31.1%, while ODR segment revenue of $39.2 million increased by $5.9 million, or 17.6%.
Gross margin increased to 18.9%, up from 14.8%. This increase was mainly driven by the mix of higher margin ODR segment work, coupled with improved GCR segment margins. GCR gross profit decreased $2.1 million, or 14.1%, largely due to lower revenue despite increased margins. ODR gross profit increased $2.4 million, or 25.6%, due to an increase in revenue at higher margins. On a dollar basis, total gross profit was $24.5 million, compared to $24.2 million. In addition, the increase in gross margin was also attributable to total net gross profit write-ups of $1.2 million compared to total net gross profit write-downs of $0.8 million.
Selling, general and administrative expenses increased by approximately $1.3 million, to $18.3 million, compared to $17.0 million. This increase was characterized by temporary, lower operating expenses resulting from pandemic-driven operational reductions in the third quarter of 2020 and our investment in ODR expansion in 2021, such as the opening of our new Nashville office in 2021 in order to attract additional healthcare ODR business. As a percent of revenue, selling, general and administrative expenses were 14.2%, up from 10.4%.
Interest expense, net was $0.4 million compared to $2.2 million. This significant decrease was due to our refinancing of the 2019 debt facilities in February 2021, replacing them with debt facilities that carry a lower cost of financing, as well as a lower overall level of indebtedness.
Net income for the third quarter of 2021 was $4.0 million as compared to $2.5 million. Diluted income per share was $0.38 as compared to $0.31. The increase in net income was primarily attributable to increased gross profit on lower revenue as well as the aforementioned decrease in net interest expense. In addition, during the third quarter of 2020, we recognized a loss of $1.4 million to reflect the change in fair value of warrant liability.
Adjusted EBITDA was $8.1 million as compared to $8.8 million, a decrease of 8.0%. The decrease in Adjusted EBITDA was primarily attributable to the $1.3 million increase in selling, general and administrative expenses, most of which was incurred to fund our ODR expansion.
Net cash provided by operating activities was $7.8 million as compared to $12.8 million. Cash flows provided by operating activities were primarily due to an increase in accounts payable, including retainage, an increase in accrued expenses and other current liabilities and net income for the period of $4.0 million, partially offset by an increase in accounts receivable due to the timing of billings and collections and a decrease in our overbilled position due to the reduction in GCR revenue in 2021 and the timing of contract billings and the recognition of contract revenue.

Balance Sheet and Backlog

At September 30, 2021, we had cash and cash equivalents of $33.3 million. We had current assets of $209.7 million and current liabilities of $143.1 million at September 30, 2021, representing a current ratio of 1.47x compared to 1.33x at December 31, 2020. Working capital was $66.6 million at September 30, 2021, an increase of $17.5 million from December 31, 2020. At September 30, 2021, we had no borrowings against our revolving credit facility, other than for standby letters of credit totaling $3.4 million, and carried a term loan balance of $26.5 million.

Total backlog at September 30, 2021 was $414.9 million as compared to $444.4 million as of December 31, 2020. At September 30, 2021, GCR and ODR segment backlog accounted for $345.5 million and $69.4 million of that consolidated total, respectively.

2021 Guidance

We affirm our guidance for 2021 as follows:

*Revenue*		$480 million - $510 million
*Adjusted EBITDA*		$23 million - $25 million

With respect to projected 2021 Adjusted EBITDA, a quantitative reconciliation is not available without unreasonable effort due to the high variability, complexity and low visibility with respect to taxes and other items, which are excluded from Adjusted EBITDA. We expect the variability of this item to have a potentially unpredictable, and potentially significant, impact on future GAAP financial results.

Non-GAAP Financial Measures

In assessing the performance of our business, management utilizes a variety of financial and performance measures. The key measure is Adjusted EBITDA, a non-GAAP financial measure. 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 believe that Adjusted EBITDA is 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 Adjusted EBITDA is 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. Our calculation of Adjusted EBITDA, 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 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.
