Consolidated Revenue of $121.0 Million Driven by Continued Growth in Owner Direct Relationships Segment

Gross Margins Improved to 15.4%; Diluted EPS of $0.07

Conference Call Scheduled for 9:00 am ET on August 13, 2021

Limbach Holdings, Inc. (NASDAQ:LMB) today announced its financial results for the quarter ended June 30, 2021. Consolidated revenue improved to $121.0 million, or 6.8%, compared with the first quarter of 2021 as business conditions strengthened relative to the first quarter of 2021. ODR⁽¹⁾ segment revenue accounted for 27.7% of consolidated revenue in the second quarter of 2021 compared to 21.6% in the second quarter of 2020. Consolidated gross margin of 15.4% increased 24 basis points sequentially, and 40 basis points year-over-year 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 second quarter of 2021, the ODR segment accounted for more than 50% of consolidated gross profit.

Charlie Bacon, Limbach's President and Chief Executive Officer, said, "Our second quarter reflected steady improvement in activity levels from the first quarter as business and economic conditions improved. We're pleased with the sequential and year-over-year growth in ODR revenue and the continued strength of ODR margins, both of which have been key objectives. In the GCR segment, substantially all of the work required to meet our current year total revenue guidance is in backlog and promised work from customer commitments not yet contracted. In our ODR segment, much of the work required to meet our current year total revenue guidance is included in backlog, promised work from customer commitments not yet contracted, our maintenance base, and expected related pull through work. We also continue to see an improving pipeline of opportunities as our customers accelerate their capital spending tied to the reopening and expanding economy."

Mr. Bacon continued, "Our ODR revenue growth is expected to exceed historical rates. However, that growth, while substantial and expected to be in excess of 25% for the year, will fall slightly short of our original expectation. GCR revenue is tracking ahead of plan due to strong sales in the second quarter of 2021, but given the lower margins in that segment and our expectation for selling, general and administrative expense to continue as planned based on the investments into the ODR segment, we are tightening our Adjusted EBITDA guidance range to $23 million to $25 million for 2021 based on the likely mix between GCR and ODR revenue. Based on our current backlog, opportunities in hand, and our work schedules for the second half of 2021, we are tightening our revenue guidance range to $480 million to $510 million. We remain cautiously optimistic about the balance of 2021 despite the emergence of the Delta Variant of COVID-19 becoming more prevalent within the areas we operate. Due to this uncertainty, we are currently not able to forecast any additional impacts from the pandemic during the second half of 2021."

Mr. Bacon concluded, "We have noted that 2021 would be a year of transition for Limbach and I am pleased to report that this process is underway. As we look forward to the second half of 2021, our projections show the ODR segment contributing as much as 30% of our consolidated revenue for the year, helping us drive gross margin improvement of up to 150 basis points. ODR revenue drives higher margins, and our stated goal has been to continuously drive a greater mix of our total revenue towards this segment."

⁽¹⁾As of January 1, 2021, the Company 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 June 30, 2021 compared to the three months ended June 30, 2020:

Consolidated revenue was $121.0 million for the second quarter of 2021, a decrease of 10.5% from the second quarter of 2020 revenue of $135.2 million. GCR segment revenue of $87.6 million was down 17.4%, while ODR segment revenue of $33.5 million increased by $4.2 million, or 14.4%.
Gross margin increased to 15.4% for the second quarter of 2021, up from 15.0% for the second quarter of 2020. This increase was mainly driven by the mix of higher margin ODR segment work. GCR gross profit decreased $3.3 million, or 27.2%, largely due to lower revenue at reduced margins. ODR gross profit increased $1.7 million, or 20.7%, due to an increase in revenue at higher margins. On a dollar basis, total gross profit was $18.7 million for the second quarter of 2021, compared to $20.3 million for the second quarter of 2020.
Selling, general and administrative expenses increased by approximately $3.5 million, to $17.2 million, during the second quarter of 2021 as compared to $13.8 million during the second quarter of 2020. This increase is characterized by lower operating expenses resulting from pandemic-driven operational reductions in the second quarter of 2020 and our investment in ODR expansion in 2021, such as the focus on sales resources in the ODR segment and 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% for the second quarter of 2021, up from 10.2% for the second quarter of 2020. Second quarter 2021 selling, general and administrative expenses were consistent with levels reported during the first quarter of 2021.
Interest expense, net was $0.5 million for the second quarter of 2021 compared to $2.1 million for the second quarter of 2020. This significant decrease was due to the Company's refinancing of its 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 second quarter of 2021 was $0.7 million as compared to $2.9 million for the second quarter of 2020. Diluted income per share was $0.07 for the second quarter of 2021 as compared to $0.37 for the second quarter of 2020. Second quarter 2020 net income benefited significantly from unusually low selling, general and administrative expenses, as previously noted, and an unexpected high margin emergency COVID-19 response project and the resulting income contribution.
Adjusted EBITDA for the second quarter of 2021 was $3.6 million as compared to $8.1 million for the second quarter of 2020, a decrease of 55.6%. The decrease in Adjusted EBITDA was primarily attributable to the $3.5 million increase in selling, general and administrative expenses during the second quarter of 2021, most of which was incurred to fund our ODR expansion, coupled with lower GCR segment gross profit as compared to the second quarter of 2020 and the absence of an unexpected high margin emergency COVID-19 response project which benefited the prior year period, as previously noted.
Net cash used in operating activities was $7.2 million for the second quarter of 2021, as compared to net cash provided by operating activities of $18.9 million for the second quarter of 2020. Cash flows used in operating activities during the second quarter of 2021 were negatively affected primarily due to an increase in accounts receivable due to the timing of billings and collections, a decrease in accrued expenses and other current liabilities primarily due to timing of payments, 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, offset by an increase in accounts payable, including retainage, as compared to the second quarter of 2020.

Balance Sheet and Backlog

At June 30, 2021, the Company had current assets of $199.7 million and current liabilities of $137.9 million, representing a current ratio of 1.45x. As of December 31, 2020, the Company's current ratio was 1.33x. Working capital was $61.8 million at June 30, 2021, an increase of $12.7 million from December 31, 2020. At June 30, 2021, the Company had no borrowings against its revolving credit facility, other than for standby letters of credit totaling $3.4 million, and carried a term loan balance of $28.0 million.

Total backlog at June 30, 2021 was $439.5 million as compared to $444.4 million as of December 31, 2020. At June 30, 2021, GCR and ODR segment backlog accounted for $378.9 and $60.6 million of that consolidated total, respectively.

2021 Guidance

The Company is revising its guidance for 2021 as follows:

	Current	Previous
*Revenue*	$480 million - $510 million	$480 million - $520 million
*Adjusted EBITDA*	$23 million - $25 million	$23 million - $27 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. The Company expects 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 (loss) 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 (loss) 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 (loss) 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.
