Impact of the COVID-19 Pandemic
In March 2020, the World Health Organization declared the outbreak of COVID-19 a global pandemic. The COVID-19 pandemic has caused significant disruption and volatility on a global scale resulting in, among other things, an economic slowdown and the possibility of a continued economic recession. In response to the COVID-19 outbreak, national and local governments around the world instituted certain measures, including travel bans, prohibitionsrestrictions on group events and gatherings, shutdowns of certain non-essential businesses, curfews, shelter-in-place orders and recommendations to practice social distancing. The various governmental actions have been andabated over time, but remain applicable to Limbach's operations in differentvarious ways, often varying by state. In some instances, these orders continued to result in shutdowns ofaffect certain projects in our ConstructionGCR and ServiceODR segments into the three months ended June 30, 2020.first quarter of 2021. In limited instances, during fiscal 2020, projects chose to shutdown work irrespective of the existence or applicability of government action. In most markets, construction is considered an essential business and Limbach continued to staff its projects and perform work during the three months ended June 30,fiscal 2020 and has since then seeninto 2021, and most all of the projects that were in progress restart. As Limbach's operations have been deemed essential, we have taken several measures to combatat the COVID-19 downturn.time shutdowns commenced were restarted. The duration or recurrence of these measures and the impact of COVID-19 is unknown and may be extended, and additional measures may be necessary. The New England region was the only branch where all construction activity was prohibited for a period of time. In addition to project suspensions in the New England region, each of our other branches experienced select project suspensions and were adversely impacted by COVID-19 related regulation. In May, much of the COVID-19 regulations that caused shutdowns of projects in the New England region were lifted and all of the projects that were suspended in that region resumed operations, as well as the other projects that were impacted by similar suspensions in each of our other branches also resumed. In the Service segment, the branches are currently experiencing a slowdown in some types of work due to restrictions on building access but began to see improvement start in the month of July. As building access returns, theCompany’s branches are expecting building owners to maintain or retrofit current facilities in lieu of funding larger capital projects.projects as the effects of the pandemic remain ongoing and uncertain.

During fiscal 2020 and through the first halfsecond quarter of 2020, we took2021, the Company continued to take several actions to combat the adverse impacts that the COVID-19 outbreak induced downturn inhad on our business including, but not limited to the following:

•    Identification of projects that have been shut down and methods for seeking to preserve any contractual entitlement that may exist;exist to recover monetary and time impacts;

•    Establishment of a task force to identify possible types and areas of impact from COVID-19 for both shutdown and     continuing operations;
•    Examination of the Company's productivity and potential impact on gross profit as a result of COVID-19;
•    Implementation of the Company's pandemic response plan;
•    Implemented our furlough and work schedule reduction plans, as well as permanent reductions in force; and
Suspended•    Temporarily suspended substantially all discretionary, non-essential expenditures, including but not limited to, auto allowances, deferral of rent ranging between 1 and 3 months,months; and
•    A temporary 10% salary reduction for a select group of corporate and regional management, along with a 10% fee reduction in director compensation, and cost reduction opportunities identified by our external consultant; andconsultant.
Continued our hiring freeze.

During the month of July 2020, with the substantial restart and return of project and service work, wethe Company removed the 10% salary reduction for the select group of corporate and regional management, along with the fee reduction for director compensation, returned auto allowances, reinstated positions, removed schedule reduction plans and discontinued our hiring freeze.
In addition During the remainder of 2020 and into 2021, the Company reinstituted limited travel and in-person meetings, along with encouraging employees to return to the above actions taken duringoffice, field and training settings in a partial, flexible manner that is consistent with our Work From Home Policy and our COVID-19 Policy. The Company has remained steadfastly committed to our COVID-19 Policy as our work environment evolves in response to the initialchanging landscape of the pandemic and in response to the increasing availability of vaccinations.

We continue to monitor the short and long term impacts of the pandemic. While our employees and customers have adapted to a new work environment and there continues to be scientific, societal and economic progress to address the effect of COVID-19, there remains significant uncertainty about the future impacts of the pandemic, including the potential effects on our operations. We remain cautiously optimistic about the markets in which we operate and the customers we serve; however, the spread of more contagious variants of the virus, including the current rapid increase of the Delta Variant, may impact economic activity and could cause projects to be delayed or canceled, or we may experience access restrictions to our customers’ facilities and project sites. Additionally, the spread of the Delta Variant has the near-term possibility of causing some state and local governments where we work to reinstitute restrictions that could impact our customers, vendors and our own ability to perform existing projects.

The ongoing effects of the pandemic, including decreased consumer confidence and economic instability, can make it extremely difficult for our customers, our vendors and us to accurately forecast and plan future business activities, and could cause constrained spending on our services, delays and a lengthening of our business development efforts, the demand for more favorable pricing or other terms, and/or difficulty in collection of our accounts receivable. Our clients may face budget deficits or other financial constraints that prohibit them from funding proposed and existing projects. During the fourth quarter of 2020 and the first half of 2021, several of our business units experienced slowdowns in the closing of sales related to the ongoing effects of the pandemic, which impacted our revenue and profitability. These impacts may continue as the pandemic persists. Further, ongoing economic instability in the global markets, including from the pandemic, could limit our ability to access the capital markets at a time when we would like, or need, to raise capital, which could have an impact on our ability to react to changing business conditions or new opportunities. If economic conditions remain uncertain or weaken, or spending continues to be reduced, our financial condition and results of operations may be adversely affected.

The Company continues to take steps to minimize the adverse impacts of the COVID-19 pandemic on ourits business and to protect the safety of ourits employees, and continuethe Company continues to emphasize wearing of masks, more frequent washing of hands and tools, social distancing, wearing masks and work protocols. Limbach's COVID-19 policyPolicy is written based on the best practices provided by the Centers for Disease Control and Prevention (“CDC”) and Occupational Safety and Health Administration for essential workers. Our updated Work From Home Policy, along with the Company's business continuity planning and information technology enhancements have enabled an orderly transition to remote work and facilitated social distancing for salaried employees. Although the Company has not mandated vaccinations for employees, it is encouraging all employees to be vaccinated, in accordance with CDC recommendations.


Testing and inpatient treatment for COVID-19 is covered under our medical plan and fees have been waived since the onset of the pandemic. Counseling is available through our employee assistance plan to assist employees with financial, mental and emotional stress related to the virus and other issues.
Management continues to perform a reforecast of its 2020 and 2021 financial plans on a monthly basis. For the period ended June 30, 2020, we assessed a variety of factors, including but not limited to projects in our Construction and Service segments currently being impacted or delayed, construction industry financial forecasts for the remainder of 2020, and the impact of certain cost-cutting measures implemented during the end of the our first fiscal quarter. Based on these factors we assumed a measured recovery in revenue and gross profit that commenced in May and returning to normal revenue and gross profit levels in Q4 2020. However, it is difficult to identify the nature and extent of the COVID-19 impacts and fully estimate any costs associated with its impacts. We believe these impacts will become more defined over time and any actual cost impacts are expected to be more readily discernible as projects continue to progress towards completion. Based on management's current reforecast, management projects compliance with the financial covenants associated with its current credit agreements for the next 12 months.
While management has used all currently available information in its forecasts, the ultimate impact of the COVID-19 pandemic on our business, results of operations, financial condition and cash flows is highly uncertain, cannot be accurately predicted and is dependent on future developments, including the duration of the pandemic and the related length of its impact on the global economy, such as a lengthy or severe recession or any other negative trend in the U.S. or global economy, and any new information that may emerge concerning the COVID-19 outbreak and the actions to contain it or treat its impact. The continued impact on our business as a result of COVID-19 pandemic could result in a material adverse effect on our business, results of operations, financial condition, liquidity and prospects in the near-term and beyond 2020.
On March 27, 2020, the Coronavirus Aid Relief and Economic Security Act (the “CARES Act”) was signed into law. The CARES Act provides opportunities for additional liquidity, loan guarantees and other government programs to support companies affected by the COVID-19 pandemic and their employees. The Company elected to utilize the option to defer payment of certain payroll taxes and utilize certain income tax updates (i.e. NOL carryback).

Note 3 – Accounting Standards
Recently Adopted Accounting Standards
New Revenue Recognition Standard

In May 2014,December 2019, the FASB issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with CustomersASU 2019-12, Income Taxes (Topic 606)740), as amended by subsequent ASUs (collectively, “ASCwhich affects general principles within Topic 606”) which amends740, and is meant to simplify and reduce the existingcost of accounting standards for revenue recognitionincome taxes. It removes certain exceptions to the general principles in Topic 740 and establishes principles for recognizing revenue upon the transfer of promised goods or services to customerssimplifies areas including franchise taxes that are partially based on income, transactions with a government that result in a step up in the expected consideration to be receivedtax basis of goodwill, the incremental approach for intraperiod tax allocation, interim period income tax accounting for year-to-date losses that exceed anticipated losses and enacted changes in exchangetax laws in interim periods. The changes are effective for those goods or services. Effective December 31, 2019, management adopted ASC Topic 606 for the annual and quarterly periods beginning after January 1, 2019 using a modified retrospective transition approach. The financial information for the three and six months ended June 30, 2019 has been recast to conform to the new standard.

December 15, 2020. The adoption of ASC Topic 606 did not have an impact on revenue of our fixed-price and other service contracts. However, it did impact revenue of our construction-type contracts within our construction and service segments specifically in accounting for warranties. For many of our construction-type contracts, we previously included assurance-type warranties in total estimated project costs. Under ASC Topic 606, the estimated cost of satisfying assurance-type warranties is accrued in accordance with the guidance in ASC Topic 460, Guarantees. Upon adoption of ASC Topic 606, we removed estimated and actual warranty costs at the contract level and recognized a warranty liability and expense in direct proportion to the cost-to-cost method progress towards completion of the associated contract, which had a $0.6 million effect on our opening accumulated deficit balance at January 1, 2019.

The Company also offers service-type warranties on certain construction-type projects. These service-type warranties were not accounted for as a separate performance obligation prior to the adoption of ASC Topic 606. Upon adoption of ASC Topic 606, we allocated a portion of the contract's transaction price to the service-type warranty based on its estimated standalone selling price. The accounting for service-type warranties under ASC Topic 606this pronouncement did not have a material impact on theour condensed consolidated financial statements.statements or presentation thereof.

In addition, asAlso in October 2020, the FASB issued ASU 2020-10, Codification Improvements. The amendments in this update remove references to various FASB Concepts Statements, situates all disclosure guidance in the appropriate disclosure section of January 1, 2019, we beganthe Codification, and makes other improvements and technical corrections to separately present contract assetsthe Codification.

Refer to the section, Effects of Adoption of ASC 606 and ASC 842 on Condensed Consolidated Financial Statements, below for additional disclosures around the quantitative impacts that the adoption of ASC Topic 606 had on our condensed consolidated financial statements.

New Leasing Standard

In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-02, Leases (Topic 842), as amended and supplemented by subsequent ASUs (collectively, “ASC Topic 842”). ASC Topic 842 amends the existing guidance in Accounting Standards Codification (“ASC”) 840, Leases. This ASU requires, among other things, the recognition of lease right-of-use (“ROU”) assets and lease liabilities by lessees for those leases currently classified as operating leases. Effective December 31, 2019, management adopted ASC Topic 606 for the annual and quarterly periods beginning after January 1, 2019 using a modified retrospective transition approach. The financial information for the quarter-ended June 30, 2019 has been recast to conform to the new standard.

The Company elected the package of practical expedients which provides relief from having to reassess (1) whether any expiredstatements or existing contracts contain leases, (2) lease classification (as operating or financing) for any expired or existing leases, and (3) initial direct costs for any existing leases. The Company also elected not to separate non-lease components from lease components and did not elect the hindsight practical expedient.

The adoption of ASC Topic 842 had no impact to the Company's condensed consolidated statements of operations or the consolidated cash flows provided by operating and financing activities in the Company's condensed consolidated statements of cash flows.

Refer to Note 13 - Leases for additional information regarding the impact of the adoption of ASC Topic 842 on the Company's financial position.

Additionally, refer to the section, Effects of Adoption of ASC 606 and ASC 842 on Condensed Consolidated Financial Statements, below for additional disclosures around the quantitative impacts that the adoption of ASC Topic 842 had on our condensed consolidated financial statements.

Effects of Adoption of ASC 606 and ASC 842 on Condensed Consolidated Financial Statements

The effect of the changes made to the Company's condensed consolidated June 30, 2019 balance sheet and condensed consolidated statement of operations for the three and six month periods ended June 30, 2019 for the adoption of ASC Topic 606 and ASC Topic 842 were as follows:

Recent Accounting Pronouncements
In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments, which introduced an expected credit loss methodology for the measurement and recognition of credit losses on most financial instruments, including trade receivables and off-balance sheet credit exposure. Under this guidance, an entity is required to consider a broader range of information to estimate expected credit losses, which may result in earlier recognition of losses. This ASU also requires disclosure of information regarding how a company developed its allowance, including changes in the factors that influenced management’s estimate of expected credit losses and the reasons for those changes. The guidance is effective for smaller reporting companies on January 1, 2023 with early adoption permitted. The adoption of this standard will be through a cumulative-effect adjustment to retained earnings as of the effective date. Based on our historical experience, the Company does not expect that this pronouncement will have a significant impact in its financial statements or on the estimate of the allowance for doubtful accounts.
In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740), which affects general principles within Topic 740, and is meant to simplify and reduce the cost of accounting for income taxes. It removes certain exceptions to the general principles in Topic 740 and simplifies areas including franchise taxes that are partially based on income, transactions with a government that result in a step up in the tax basis of goodwill, the incremental approach for intraperiod tax allocation, interim period income tax accounting for year-to-date losses that exceed anticipated losses and enacted changes in tax laws in interim periods. The changes are effective for annual periods beginning after December 15, 2020. Management is currently assessing the impact of this pronouncement on its condensed consolidated financial statements.

In March 2020, the FASB issued ASU 2020-03, Codification Improvements to Financial Instruments, which makes improvements to financial instruments guidance. The amendments make the Codification easier to understand and easier to apply by eliminating inconsistencies and providing clarifications. With regard to amendments related to Issue 1, Issue 2, Issue 4 and Issue 5, for public business entities, the amendments are effective upon issuance of this final ASU. With regard to amendments related to Issue 6 and Issue 7, for entities that have not yet adopted the guidance in Update 2016-13, the effective dates and the transition requirements for these amendments are the same as the effective date and transition requirements in ASU 2016-13. For entities that have adopted the guidance in ASU 2016-13, the amendments are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. We do not expect the adoption of this pronouncement to have a material impact on our condensed consolidated financial statements or presentation thereof.
The FASB alsohas issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting in March 2020. TheThis new guidance provides optional expedients for applying GAAPa limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform, on financial reporting. The risk of termination of the London Interbank Offered Rate (LIBOR), has caused regulators to undertake reference rate reform initiatives to identify alternative reference rates that are more observable or transaction based that are less susceptible to manipulation. ASU 2020-04 is effective between March 12, 2020 and December 31, 2022.

In addition, in January 2021, the FASB issued ASU 2021-01, Reference Rate Reform (Topic 848): Scope. The amendments in this update refine the scope for certain optional expedients and exceptions for contract modifications and hedge accounting to apply to derivative contracts and certain hedging relationships and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform.affected by the discounting transition. The guidance isamendments in this update are effective prospectivelyfor all entities as of March 12, 2020 through December 31, 20222022.

We do not expect the adoption of this ASU to have a material impact2021-01) on ourits condensed consolidated financial statements or presentation thereof.statements. Management has identified that its credit agreement utilizes LIBOR as a benchmark rate. Management will continue to evaluate the impact of adopting reference rate reform as the LIBOR benchmark rate within the credit agreement is phased out.
In August 2020, the FASB issued ASU 2020-06, Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity's Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity's Own Equity, which simplifies the accounting for certain financial instruments with characteristics of liabilities and equity and amends the scope guidance for contracts in an entity's own equity. The ASU addresses how convertible instruments are accounted for in the calculation of diluted earnings per share by using the if-converted method. The guidance is effective for all entities for fiscal years beginning after March 31, 2024, albeit early adoption is permitted no earlier than fiscal years beginning after December 15, 2020. Management is currently assessing the impact of this pronouncement on its condensed consolidated financial statements.

Contract assets represent the excess of contract costs and profits (or contract revenue) over the amount of contract billings to date and are classified as a current asset. Contract assets result when either: 1) the appropriate contract revenue amount has been recognized over time in accordance with ASC Topic 606, but a portion of the revenue recorded cannot be currently billed due to the billing terms defined in the contract, or 2) costs are incurred related to certain claims and unapproved change orders. Claims occur when there is a dispute regarding both a change in the scope of work and the price associated with that change. Unapproved change orders occur when a change in the scope of work results in additional work being performed before the parties have agreed on the corresponding change in the contract price. The Company routinely estimates recovery related to claims and unapproved change orders as a form of variable consideration at the most likely amount it expects to receive and to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. Claims and unapproved change orders are billable upon the agreement and resolution between the contractual parties and after the execution of contractual amendments. Increases in claims and

unapproved change orders typically result from costs being incurred against existing or new positions; decreases normally result from resolutions and subsequent billings.


The current estimated net realizable value on such claims and unapproved change orders as recorded in contract assets and contract liabilities in the condensed consolidated balance sheets was $39.4$40.1 million and $38.4$33.6 million as of June 30, 20202021 and December 31, 2019,2020, respectively. The Company anticipates that the majority of such amounts will be approved or executed within one year. The resolution of these claims and unapproved change orders may require litigation or other forms of dispute resolution proceedings.

Billings in excess of costs and estimated earnings represent the excess of contract billings to date over the amount of contract costs and profits (or contract revenue) recognized to date. The balance may fluctuate depending on the timing of contract billings and the recognition of contract revenue.


Provisions for losses are recognized in the condensed consolidated statements of operations at the uncompleted performance obligation level for the amount of total estimated losses in the period that evidence indicates that the estimated total cost of a performance obligation exceeds its estimated total revenue.

Accordingly, the Company recognized a subsidiaryloss on the early debt extinguishment related to the refinancing of $2.0 million on the refinancing date. This loss consisted of the Company, entered intowrite-off of $2.6 million of debt issuance and debt discount costs, the Credit Agreement (as amended,reversal of the “Credit Agreement”). The Credit Agreement consisted of a $25.0$2.0 million revolving line of credit (the “Credit Agreement revolver”) and a $24.0 million term loan (the “Credit Agreement term loan”), both with a maturity date of July 20, 2021. The Credit Agreement was collateralized by substantially all assets of LFS and its subsidiaries. Principal payments of $900,000CB warrants liability due to the warrants being cancelled on the Credit Agreement term loan were due at the end of each quarter, beginning September 30, 2018, through maturity of the loan, with any remaining amounts due at maturity. Outstanding borrowings on both the Credit Agreement term loanrefinancing date and the Credit Agreement revolver bore interest at either the Base Rate (as defined in the Credit Agreement) or LIBOR (as defined in the Credit Agreement), plus the applicable additional margin, payable monthly. Mandatory prepayments were required upon the occurrenceprepayment penalty and other extinguishment costs of certain events, including, among other things and subject to certain exceptions, equity issuances, changes of control of the Company, certain debt issuances, assets sales and excess cash flow.
The Credit Agreement included restrictions on, among other things and subject to certain exceptions, the Company and its subsidiaries’ ability to incur additional indebtedness, pay dividends or make other distributions, redeem or purchase capital stock, make investments and loans and enter into certain transactions, including selling assets, engaging in mergers or acquisitions and entering into transactions with affiliates. Loans under the Credit Agreement bore interest, at the borrower's option, at either Adjusted LIBOR (“Eurodollar”) or a Base Rate, in each case, plus an applicable margin. The applicable margin with respect to any Base Rate loan was 5.00% per annum and with respect to a Eurodollar loan was 6.00% per annum.
The borrower was required to make principal payments on the Bridge Term Loan in the amount of $250,000 on the last business day of March, June, September and December of each year. The Bridge Term Loan had a maturity date of April 12, 2019. The Bridge Term Loan was guaranteed by the same guarantors (including Limbach Holdings, Inc., Limbach Facility Services LLC, Limbach Holdings LLC, Limbach Company LLC, Limbach Company LP, Harper Limbach LLC and Harper Limbach Construction LLC) and secured (on a pari passu basis) by the same collateral as the other loans under the Credit Agreement.
The equity interests of the Company’s subsidiaries were pledged as security for the obligations under the Credit Agreement. The Credit Agreement included customary events of default, including, among other items, payment defaults, cross-defaults to other indebtedness, a change of control default and events of default with respect to certain material agreements. Additionally, with respect to the Company, an event of default would have been deemed to have occurred if the Company’s securities ceased to be registered with the SEC pursuant to Section 12(b) of the Exchange Act. In case of an event of default, the administrative agent would have been entitled to, among other things, accelerated payment of amounts due under the Credit Agreement, foreclose on the equity of the Company’s subsidiaries, and exercise all rights of a secured creditor on behalf of the lenders.
The additional margin applied to both the Credit Agreement revolver and Credit Agreement term loan were determined based on levels achieved under the Company’s senior leverage ratio covenant, which reflects the ratio of indebtedness divided by EBITDA for the most recently ended four quarters.

The following is a summary of the additional margin and commitment fees payable on the available revolving credit commitment:

Accounting for the 2019 Term Loans and CB Warrants
 
The CB Warrants representrepresented a freestanding financial instrument that iswas classified as a liability because the CB Warrants meetmet the definition of a derivative instrument that does not meet the equity scope exception (i.e., the CB Warrants arewere not indexed to the entity’s own equity). In addition, the material weakness penalty described above was evaluated as an embedded derivative liability and bifurcated from the 2019 Term Loans as it representsrepresented a non-credit related embedded feature that provides for net settlement.

Both the CB Warrants liability and the embedded derivative liability arewere required to be initially and subsequently measured at fair value. The initial fair values of the CB Warrants liability and the embedded derivative liability approximated $0.9 million and $0.4 million, respectively, on the Refinancing Closing Date. The Company estimated these fair values by using the Black-Scholes-Merton option pricing model and a probability-weighted discounted cash flow approach.


The CB Warrants liability iswas included in other long-term liabilities. The Company remeasured the fair value of the CB Warrants liability as of June 30,December 31, 2020 and February 24, 2021 prior to the refinancing date and recorded any adjustments as other income (expense). At June 30, 2020both February 24, 2021 and December 31, 2019,2020, the CB Warrants liability was $0.3$2.0 million. Due to the extinguishment of the CB Warrants on February 24, 2021, there was 0 liability associated with the CB Warrants recorded as of June 30, 2021. For the six months ended June 30, 2021, the Company recorded other income of $0.1 million and $0.4 million, respectively.to reflect the change in the fair value of the CB Warrants liability. The Company did not record a change in fair value of the warrant liability during the three months ended June 30, 2021 as the CB Warrants liability was extinguished as part of the debt refinancing on February 24, 2021. For the three and six months ended June 30, 2020, respectively, the Company recorded other income of $0.1 million and other expensesexpense of $0.1 million to reflect the change in fair value of the CB Warrants liability. For the three and six months ended June 30, 2019, the Company recorded other income of $0.1 million for both periods. At June 30, 2020 and December 31, 2019, the embedded derivative liability was $0.0 million as the Company remediated the material weakness associated with the embedded derivative as of December 31, 2019, and the $0.4 million embedded derivative liability was fully reversed and recorded as other income at that date.
 
The proceeds for the 2019 Refinancing Term Loan were first allocated to the CB Warrants liability and embedded derivative liability based on their respective fair values with a corresponding amount of $1.3 million recorded as a debt discount to the 2019 Term Loans. In addition, the Company incurred approximately $2.5$3.9 million of debt issuance costs, including $1.4 million related to the first amendment, for the 2019 Term Loans that have also been recorded as a debt discount. The combined debt discount from the CB Warrants liability, embedded derivative liability and the debt issuance costs arewere being amortized into interest expense over the term of the 2019 Term Loans using the effective interest method.method and were expensed on the refinancing date as a loss on early debt extinguishment. The Company recorded interest expense for the amortization of the CB Warrants liability and embedded derivative debt discounts of $0.1 million for the six months ended June 30, 2021. The Company did 0t record interest expense for the amortization of the CB Warrants liability and embedded derivative liability debt discounts for the three months ended June 30, 2021 as these debt discounts were extinguished as part of the debt refinancing on February 24, 2021. The Company recorded interest expense for the amortization of the CB Warrants liability and embedded derivative debt discounts of $0.1 million and $0.2 million for the three and six months ended June 30, 2020, respectively,respectively.

In addition to the amortization of the debt discounts into interest expense, the Company recorded $0.1 million of interest expense for the amortization of debt issuance costs related to the 2019 Refinancing Term Loan for the six months ended June 30, 2021. The Company did 0t record any interest expense for the amortization of debt issuance costs for the three months ended June 30, 2021 as the debt issuance costs were extinguished as part of the debt refinancing on February 24, 2021.

The ESPP enables eligible employees, as defined by the ESPP, the right to purchase the Company's common stock through payroll deductions during consecutive subscription periods at a purchase price of not less than 85% of the fair market value of a common share at the end of each offering period. Annual purchases by participants are limited to the number of whole shares that can be purchased by an amount equal to ten10 percent of the participant's compensation or $5,000, whichever is less. Each offering period of the ESPP lasts six months, commencing on January 1 and July 1 of each year.  The amounts collected from participants during a subscription period are used on the exercise date to purchase full shares of common stock.  Participants may withdraw from an offering before the exercise date and obtain a refund of amounts withheld through payroll deductions. Compensation cost, representing the 15% discount applied to the fair market value of common stock, is recognized on a straight-line basis over the six-month vesting period during which employees perform related services. Under the ESPP, 500,000 shares are authorized to be issued. AsIn July 2020 and January 2021, the Company issued 30,825 and 8,928 shares of its common stock, respectively, to participants in the ESPP who contributed to the plan through the June 30, 2020 noand December 31, 2020 offering periods, respectively.

On February 10, 2021 the Company entered into an underwriting agreement (“Underwriting Agreement”) with Lake Street Capital Markets, LLC (“Underwriter”) relating to an underwritten public offering (the “Offering”). On February 12, 2021 the Company sold to the Underwriter 1,783,500 shares have been issuedof its Common Stock. The Underwriting Agreement provided for purchase and sale of the Shares by the company to the Underwriter at a price of $11.28 per share. The price to the public in the Offering was $12.00 per share. In addition, under the ESPP.terms of the Underwriting Agreement, the Company granted the Underwriter a 30-day option to purchase up to an additional 267,525 shares of Common Stock to cover over-allotments, if any, on the same terms and conditions. The net proceeds to the Company from the Offering after deducting the underwriting discounts and commissions were approximately $19.8 million. On February 18, 2021, the Company received approximately $3.0 million of net proceeds for the sale of 267,525 shares in connection with the exercise of the over-allotment option.
Note 9 – Fair Value Measurements
The Company measures the fair value of financial assets and liabilities in accordance with ASC Topic 820 – Fair Value Measurements and Disclosures, which defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. ASC Topic 820 establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value and requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to measurements involving significant unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are as follows:
Level 1 — inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that are accessible at the measurement date;
Level 2 — inputs other than quoted prices included in Level 1 that are observable for the asset or liability either directly or indirectly such as quoted prices in active markets for similar assets and liabilities, quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of assets or liabilities; and
Level 3 — unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions.
18


The Company believes that the carrying amounts of its financial instruments, including cash and cash equivalents, trade accounts receivable and accounts payable consist primarily of instruments without extended maturities, which approximate fair value primarily due to their short-term maturities and low risk of counterparty default. We also believe that the carrying value of the 2019 Refinancing Agreement term loan and 2021 Wintrust Term Loan approximates its fair valuevalues due to the variable rate on such debt. As of June 30, 2020February 24, 2021 and December 31, 2019,2020, the Company determined that the fair value of its 2019 RefinancingRevolving Agreement term loan was $41.0 million$39.0 million. As of June 30, 2021, the Company determined that the fair value of its 2021 Wintrust Term Loan was $28.0 million. There were 0 outstanding borrowings on the Company's 2019 ABL Credit Agreement revolver at each date.February 24, 2021 and December 31, 2020. Such fair value isvalues were determined using discounted estimated future cash flows using level 3 inputs.
In connection with the 2019 Refinancing Agreement, on the Refinancing Closing Date, the Company issued to CB and the other lenders under the CB Warrants to purchase up to a maximum of 263,314 shares of the Company's common stock at an exercise price of $7.63 per share subject to certain adjustments, including for stock dividends, stock splits or reclassifications (refer to Note 7 - Debt). The fair value of the Company’s warrant liability is recorded in the Company’s condensed consolidated financial

statements and is determined using the Black-Scholes-Merton option pricing model. The valuation inputs include the quoted price of the Company’s common stock in an active market, volatility and expected life of the warrants, which are Level 3 inputs. Volatility is based on the actual market activity of the Company’s stock. The expected life is based on the remaining contractual term of the warrants and the risk-free interest rate is based on the implied yield available on U.S. Treasury Securities with a maturity equivalent to the warrants’ expected life.
The table below sets forth the assumptions used within the Black-Scholes-Merton option pricing model to value the Company's warrant liabilities as of June 30, 2020:
Stock price$3.70
Exercise price$7.63
Time until expiration (years)3.79
Expected volatility70.0%
Risk-free interest rate0.3%

Note 11 – Income Taxes

The Company is taxed as a C corporation.
For interim periods, the provision for income taxes (including federal, state, local and foreign taxes) is calculated based on the estimated annual effective tax rate, adjusted for certain discrete items for the full fiscal year. Cumulative adjustments to the Company's estimate are recorded in the interim period in which a change in the estimated annual effective rate is determined.

Each quarter we update our estimate of the annual effective tax rate, and if our estimated tax rate changes, we make a cumulative adjustment.
The provision (benefit)Company had an effective tax rate of 26.5% and an effective tax benefit rate of 33.2% for the three and six months ended June 30, 2021, respectively. For the three and six months ended June 30, 2020, the Company had an income taxes consisttax rate of the following:27.4% and 14.1%, respectively.
NoNaN valuation allowance was required as of June 30, 20202021 or December 31, 2019.2020.
The Company hashad previously recorded a liability for unrecognized tax benefits of $0.5 million and $0.4 million as of June 30, 2020 and December 31, 2019, respectively, which were included in accrued expenses and other current liabilities. These unrecognized tax benefits are(“UTB”) related to tax positions taken on its various income tax returns in open tax periods.

The differenceCompany filed to change an improper tax method of accounting in the effective rate for the six months ended June 30,fourth quarter of 2020 as comparedrelated to the six months ended June 30, 2019 is primarily due to the CARES Act allowingUTB that affords the Company to carryback net operating losses (“NOLs”) generatedIRS audit protection in 2018 and 2019 (originally valued atpast periods. Therefore, the total unrecognized tax benefits were reduced in the fourth quarter of 2020.

The following is a 21% federal tax rate) to prior years and generate a tax refund based on the higher 34% federal tax rate in those prior years.
On March 27, 2020, the CARES Act was signed into law making several changes to the Internal Revenue Code. The CARES Act, among other things, permits NOL carryovers to offset 100% of taxable income for tax years beginning before 2021. In addition, the CARES Act allows NOLs incurred in 2018, 2019 and 2020 to be carried back to eachreconciliation of the five preceding years to generate a $1.6 million refund of previously paid income taxes. The CARES Act contains modification on the limitation of business interest forbeginning and ending unrecognized tax years beginning in 2019 and 2020. The modifications to Section 163(j) increase the allowable business interest deduction from 30% of adjusted taxable income to 50% of adjusted taxable income. The CARES Act also accelerates the refund of AMT credits that were previously accumulated.benefits:

Note 12 – Operating Segments
The Company determined its operating segments on the same basis that it assesses performance and makes operating decisions. The Company manages and measures the performance of its business in two2 distinct operating segments:segments. As of January 1, 2021, the Company renamed its existing 2 reportable segments to reflect its 2 distinct approaches to our customer base and to better align with our owner direct strategy. The previously named Construction and Service.Segment is now known as General Contractor Relationships (“GCR”); the previously named Service Segment is now known as Owner Direct Relationships (“ODR”). These segments are reflective of how the Company’s Chief Operating Decision Maker (“CODM”) reviews operating results for the purposes of allocating resources and assessing performance. The Company's CODM is comprised of its Chief Executive Officer, Chief Financial Officer and Chief Operating Officer.
The accounting policies of the segments are the same as those described in the summary of significant accounting policies. The CODM evaluates performance based on income from operations of the respective segments after the allocation of Corporatecorporate office operating expenses. In accordance with ASC Topic 280 – Segment Reporting, the Company has elected to aggregate all of the construction branchesactivity into one Construction1 GCR reportable segment and all of the service branches into one Service1 ODR reportable segment. All transactions between segments are eliminated in consolidation. Our Corporatecorporate department provides general and administrative support services to our two2 operating segments. The CODM allocates costs between segments for selling, general and administrative expenses and depreciation expense.
All of the Company’s identifiable assets are located in the United States, which is where the Company is domiciled. The Company does not have sales outside the United States. The Company does not identify capital expenditures and total assets by segment in its internal financial reports due in part to the shared use of a centralized fleet of vehicles and specialized equipment. Interest expense is not allocated to segments because of the corporate management of debt service including interest.

Summarized segment information is as follows:

(1)Starting January 1, 2020, we changed the methodology in which we present our corporate selling, general and administrative expenses to our CODM to better reflect the way the business is managed. Under this new methodology, all corporate expenses except for stock-based compensation are allocated to our Construction and Service segments. For comparability purposes, we reclassified our selling, general and administrative expense segment amounts for the three and six months ended June 30, 2019 to align with this updated allocation methodology.

Note 13 - Leases


The Company leases real estate, trucks and other equipment. The determination of whether an arrangement is, or contains, a lease is performed at the inception of the arrangement. Classification and initial measurement of the right-of-use asset and lease liability are determined at the lease commencement date. The Company elected the short-term lease measurement and recognition

exemption; therefore, leases with an initial term of 12 months or less are not recorded on the condensed consolidated balance sheets.


The Company's arrangements include certain non-lease components such as common area and other maintenance for leased real estate, as well as mileage, fuel and maintenance costs related to leased vehicles. For all leased asset classes, the Company has elected to not separate non-lease components from lease components and will account for each separate lease component and non-lease component associated with the lease as a single lease component. The Company does not guarantee any residual value in its lease agreements, and there are no material restrictions or covenants imposed by lease arrangements. Real estate leases typically include one or more options to extend the lease. The Company regularly evaluates the renewal options, and when they are reasonably certain of exercise, the Company includes the renewal period in its lease term. For our leased vehicles, the Company uses the interest rate implicit in its leases with the lessor to discount lease payments at the lease commencement date. When the implicit rate is not readily available, as is the case with our real estate leases, the Company uses quoted borrowing rates on our secured debt.

Surety. The terms of our construction contracts frequently require that we obtain from surety companies, and provide to our customers, payment and performance bonds (“Surety Bonds”) as a condition to the award of such contracts. The Surety Bonds secure our payment and performance obligations under such contracts, and we have agreed to indemnify the surety companies for amounts, if any, paid by them in respect of Surety Bonds issued on our behalf. In addition, at the request of labor unions representing certain of our employees, Surety Bonds are sometimes provided to secure obligations for wages and benefits payable to or for such employees. Public sector contracts require Surety Bonds more frequently than private sector contracts, and accordingly, our bonding requirements typically increase as the amount of public sector work increases. As of June 30, 2020,2021, the Company had approximately $128.6$265.3 million in surety bonds outstanding. The Surety Bonds are issued by surety companies in return for premiums, which vary depending on the size and type of bond.

Collective Bargaining Agreements. Many of the Company’s craft labor employees are covered by collective bargaining agreements. The agreements require the Company to pay specified wages, provide certain benefits and contribute certain amounts to multi-employer pension plans. If the Company withdraws from any of the multi-employer pension plans or if the plans were to otherwise become underfunded, the Company could incur additional liabilities related to these plans. Although the Company has been informed that some of the multi-employer pension plans to which it contributes have been classified as “critical” status, the Company is not currently aware of any significant liabilities related to this issue.
Note 16 – Remaining Performance Obligations
Remaining performance obligations represent the transaction price of firm orders for which work has not been performed and exclude unexercised contract options. The Company’s remaining performance obligations includes projects that have a written award, a letter of intent, a notice to proceed or an agreed upon work order to perform work on mutually accepted terms and conditions.
As of June 30, 2021, the aggregate amount of the transaction prices allocated to the remaining performance obligations of the Company's GCR and ODR segment contracts were $378.9 million and $44.2 million, respectively. As of December 31, 2020, the aggregate amount of the transaction prices allocated to the remaining performance obligations of the Company's ConstructionGCR and ServiceODR segment contracts were $408.8$393.5 million and $46.6 million, respectively. As of December 31, 2019, the aggregate amount of the transaction prices allocated to the remaining performance obligations of the Company's Construction and Service segment contracts were $504.2 million and $41.9$35.7 million, respectively.
We estimate that 56%44% and 100%62% of our ConstructionGCR and ServiceODR segment remaining performance obligations as of June 30, 2020,2021, respectively, will be recognized as revenue during 2020,2021, with the substantial majority of remaining performance obligations to be recognized within 24 months, although the timing of the Company's performance is not always under its control.
Additionally, the difference between remaining performance obligations and backlog is due to the exclusion of a portion of the Company’s serviceODR agreements under certain contract types from the Company’s remaining performance obligations as these contracts can be canceled for convenience at any time by the Company or the customer without considerable cost incurred by the customer. Additional information related to backlog is provided in “Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations” of this Quarterly Report on Form 10-Q.
Note 17 – Management Incentive Plans
The Company initially adopted the Omnibus Incentive Plan on July 20, 2016 for the purpose of: (a) encouraging the profitability and growth of the Company through short-term and long-term incentives that are consistent with the Company’s objectives; (b) giving participants an incentive for excellence in individual performance; (c) promoting teamwork among participants; and (d) giving the Company a significant advantage in attracting and retaining key employees, directors and consultants. To accomplish such purposes, the Omnibus Incentive Plan provides that the Company may grant options, stock appreciation rights, restricted shares, restricted stock units, performance-based awards (including performance-based restricted shares and restricted stock units), other share based awards, other cash-based awards or any combination of the foregoing.
Following the further amendment and restatement of the Omnibus Incentive Plan upon approval of the Company's stockholders on July 14, 2020,June 16, 2021, the Company has reserved a total of 1,650,0002,250,000 shares of its common stock for issuance under the Omnibus Incentive Plan. The number of shares issued or reserved pursuant to the Omnibus Incentive Plan will be adjusted by the plan administrator, as they deem appropriate and equitable, as a result of stock splits, stock dividends, and similar changes in the Company’s common stock. In connection with the grant of an award, the plan administrator may provide for the treatment of such award in the event of a change in control. All awards are made in the form of shares only. See Note 18 - Subsequent Events.
Service-Based Awards
During the first six months of 2020,2021, the Company granted 118,633120,899 service-based RSUs to its executives, certain employees, and non-employee directors under the Omnibus Incentive Plan.

Upon approval
29

Table of the Company's stockholders on May 30, 2019, the Company adopted the Limbach Holdings, Inc. 2019 Employee Stock Purchase Plan (“the ESPP”). On January 1, 2020, the ESPP went into effect. The ESPP enables eligible employees, as defined by the ESPP, the right to purchase the Company's common stock through payroll deductions during consecutive subscription periods at a purchase price of 85% of the fair market value of a common share at the end of each offering period. Annual purchases by participants are limited to the number of whole shares that can be purchased by an amount equal to ten percent of the participant's compensation or $5,000, whichever is less. Each offering period of the ESPP lasts six months, commencing on January 1st and July 1st of each year.  The amounts collected from participants during a subscription period are used on the exercise date to purchase full shares of common stock.  Participants may withdraw from an offering before the exercise date and obtain a refund of amounts withheld through payroll deductions. Compensation cost, representing the 15% discount applied to the fair market value of common stock, is recognized on a straight-line basis over the six-month vesting period during which employees perform related services. Under the ESPP 500,000 shares are authorized to be issued. As of June 30, 2020, no shares have been issued under the ESPP. See Note 18 - Subsequent Events.Contents

Note 18 – Subsequent Events
At the 2020 Annual Meeting, held on July 14, 2020, the stockholders approved the further amendments to the Company's amended and restated Omnibus Incentive Plan to increase the number of shares of the Company's common stock that may be issued pursuant to awards by 500,000, for a total of 1,650,000 shares, and extend the term of the plan so that it will expire on the tenth anniversary of the date the stockholders approve the Amended Incentive Plan.

In July 2020, we issued 30,825 shares of our common stock to participants in the ESPP who contributed to the plan through June 30, 2020. Stock compensation expense related to the ESPP was $17 thousand for the three and six months ended June 30, 2020.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations
The following discussion should be read in conjunction with the condensed consolidated financial statements and related notes thereto included elsewhere in this Quarterly Report on Form 10-Q. In addition to historical information, this discussion contains forward-looking statements that involve risks, uncertainties and assumptions that could cause actual results to differ materially from our management’s expectations. Factors that could cause such differences are discussed in “Forward-Looking Statements” and “Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended December 31, 20192020 and in subsequent Quarterly Reports on Form 10-Q. We assume no obligation to update any of these forward-looking statements.
Overview
We are an industry-leading commercial specialty contractorintegrated building systems solutions firm whose expertise is in the areasdesign, modular prefabrication, installation, management and maintenance of heating, ventilation, and air conditioning (“HVAC”), mechanical, electrical, plumbing electrical and building controls through designcontrol systems. Our market sectors primarily include the following: healthcare, life sciences, data centers, industrial and construction of newlight manufacturing, entertainment, education and renovated buildings, maintenance services, energy retrofits and equipment upgrades for privategovernment. Our customers and federal, state, and local public agencies inare primarily located throughout Florida, California, Massachusetts, New Jersey, Pennsylvania, Delaware, Maryland, Washington, D.C., Virginia, West Virginia, Ohio and Michigan. We operateAs of January 1, 2021, the Company renamed its existing two reportable segments to reflect our businessdistinct 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”); the previously named Service Segment is now known as Owner Direct Relationships (“ODR”). The Company operates in two segments that are based on the relationship with its customer, (i) Construction,GCR, in which wethe Company generally manage largemanages new construction or renovation projects that involve primarily HVAC, plumbing or electrical services and are awarded to the Company by general contractors or construction managers and (ii) Service,ODR, in which we provide facilitythe Company provides maintenance or servicesservice primarily on HVAC, plumbing or electrical systems. Our branchessystems, building controls and corporate headquarters are located in the United States.specialty contracting projects direct to, or assigned by, building owners or property managers. This work is primarily performed under fixed price, modified fixed price, and time and material contracts over periods of typically less than two years.
JOBS Act
We ceased to qualify as an “emerging growth company” pursuant to the Jumpstart Our Business Startups Act on December 31, 2019, at which time we reached the last day of the fiscal year following the fifth anniversary of our initial public offering of common equity securities.
Key Components of Condensed Consolidated Statements of Operations
Revenue
We generate revenue principally from fixed-price construction contracts to deliver HVAC, plumbing, and electrical construction services to our customers. The duration of our contracts generally ranges from six months to two years. Revenue from fixed price contracts is recognized on the cost-to-cost method, measured by the relationship of total cost incurred to total estimated contract costs. Revenue from time and materials contracts is recognized as services are performed. We believe that our extensive experience in HVAC, plumbing, and electrical projects, and our internal cost review procedures during the bidding process, enable us to reasonably estimate costs and mitigate the risk of cost overruns on fixed price contracts.

We generally invoice customers on a monthly basis, based on a schedule of values that breaks down the contract amount into discrete billing items. Costs and estimated earnings in excess of billings on uncompleted contracts are recorded as a contract asset until billable under the contract terms. Billings in excess of costs and estimated earnings on uncompleted contracts are recorded as a contract liability until the related revenue is recognizable.
Cost of Revenue
Cost of revenue primarily consists of the labor, equipment, material, subcontract, and other job costs in connection with fulfilling the terms of our contracts. Labor costs consist of wages plus taxes, fringe benefits, and insurance. Equipment costs consist of the ownership and operating costs of company-owned assets, in addition to outside-rented equipment. If applicable, job costs include estimated contract losses to be incurred in future periods. Due to the varied nature of our services, and the risks associated therewith, contract costs as a percentage of contract revenue have historically fluctuated and we expect this fluctuation to continue in future periods.
Selling, General and Administrative Expenses
Selling, general and administrative expenses consist primarily of personnel costs for our administrative, estimating, human resources, safety, information technology, legal, finance and accounting employees and executives. Also included are non-personnel costs, such as travel-related expenses, legal and other professional fees and other corporate expenses to support the growth of our business and to meet the compliance requirements associated with operating as a public company. Those costs include accounting, human resources, information technology, legal personnel, additional consulting, legal and audit fees, insurance costs, board of directors’ compensation and the costs of achieving and maintaining compliance with Section 404 of the Sarbanes-Oxley Act.
Starting January 1, 2020, we changed the methodology in which we present our corporate selling, general and administrative expenses to our CODM (as defined below) to better reflect the way the business is managed. Under this new methodology, all corporate expenses except for stock-based compensation are allocated to our Construction and Service segments. For comparability purposes, we reclassified our selling, general and administrative expense segment amounts for the three and six months ended June
30 2019 to align with this updated allocation methodology.


Amortization of Intangibles
Amortization expense represents periodic non-cash charges that consist of amortization of various intangible assets, primarily including leasehold interests and certain customer relationships - Service and backlog - Construction.in the ODR segment.
Other Income/Expense
Other income/expense, net consists primarily of interest expense incurred in connection with our debt, net of interest income, loss on early debt extinguishment, gain and gains and lossesloss on the sale of property and equipment and changechanges in fair value of warrant liability. Deferred financing costs are amortized to interest expense using the effective interest method.
Income Taxes
We are taxed as a C corporation and our financial results include the effects of federal income taxes which are paid at the parent level.
For interim periods, the provision for income taxes (including federal, state and local taxes) is calculated based on the estimated annual effective tax rate. The Company accounts for income taxes in accordance with ASC Topic 740 - Income Taxes, which requires the use of the asset and liability method. Under this method, deferred tax assets and liabilities and income or expense are recognized for the expected future tax consequences of temporary differences between the financial statement carrying values and their respective tax bases, using enacted tax rates expected to be applicable in the years in which the temporary differences are expected to reverse. Changes in deferred tax assets and liabilities are recorded in the provision for income taxes.
Operating Segments
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”); the previously named Service Segment is now known as Owner Direct Relationships (“ODR”). We manage and measure the performance of our business in these two operating segments: Construction and Service.segments. These segments are reflective of how the Company’s Chief Operating Decision Makers (“CODM”) reviews its operating results for the purposes of allocating resources and assessing performance. Our CODM is comprised of our Chief Executive Officer, Chief Financial Officer and Chief Operating Officer. The CODM evaluates performance and allocates resources based on operating income, which is profit or loss from operations before “other” corporate expenses, income tax provision (benefit), if any.

The accounting policies of the segments are the same as those described in the summary of significant accounting policies. The CODM evaluates performance based on income from operations of the respective branches after the allocation of corporate office operating expenses. In accordance with ASC Topic 280 – Segment Reporting, the Company has elected to aggregate all of the constructionGCR work performed at branches into one ConstructionGCR reportable segment and all of the serviceODR work performed at branches into one ServiceODR reportable segment. All transactions between segments are eliminated in consolidation. Our corporate department provides general and administrative support services to our two operating segments. We allocate costs between segments for selling, general and administrative expenses and depreciation expense. Interest expense is not allocated to segments because of the corporate management of debt service. See Note 12 – Operating Segments in the notes to condensed consolidated financial statements.
We do not identify capital expenditures and total assets by segment in our internal financial reports due in part to the shared use

$2.1 million of 2019, including debt issuance and discount amortization, associated with the 2019 Refinancing Agreement that occurred on April 12, 2019. Accordingly, a loss on debt extinguishment of $0.5 million was recognized on that same date.

Income Taxes
For the three months ended June 30, 2020, the Company recorded a $1.0 million current tax provision and a $0.2 million deferred income tax benefitinterest expense for the three months ended June 30, 2020. ForThe reduction in interest expense year over year is due to the three months ended June 30, 2019,refinancing of the higher interest rate debt with a lower interest rate debt instrument in late February 2021.
Income Taxes
The Company recorded a $0.1$0.3 million current federal tax benefit. In addition, the Company recorded a $0.5and $1.1 million deferred federal income tax benefitprovision for the three months ended June 30, 2019.2021 and 2020, respectively.

The difference in the effective rate for the three months ended June 30, 2020 as compared to 2019 is primarily due to the CARES Act allowing the Company to carryback net operating losses generated in 2018 and 2019 (originally valued at a 21% federal tax rate) to prior tax years and generate a tax refund based on the higher 34% federal tax rate in those prior years. The refund generated by this carryback has been netted against income taxes payable and has been included in income tax receivable as $0.7 million in the condensed consolidated balance sheet at June 30, 2020.respectively.

Under this new methodology, all corporate expenses except for stock-based compensation are allocated to our Construction and Service segments. For comparability purposes, we reclassified our selling, general and administrative expense segment amounts for the six months ended June 30, 2019 to align with this updated allocation methodology.

The increase in interest expense was primarily due to the Company's higher interest rates on the refinanced debt obligations, including debt issuance and discount amortization, associated with the 2019 Refinancing Agreement that occurred on April 12, 2019. The Company also recorded other income of $0.5 million for a loss on debt

Income Taxes
The Company recorded a $0.2 million current federal tax benefit and a $0.1 million current state and local income tax benefit for the six months ended June 30, 2020. In addition,The reduction in interest expense year over year is due to the refinancing of the higher interest rate debt with a lower interest rate debt instrument in late February 2021. The Company recognized a loss on early debt extinguishment of $2.0 million in connection with its refinancing of the 2019 Refinancing Term Loan and 2019 Revolving Credit Facility with the Wintrust Term Loan and Wintrust Revolving Loan.

Construction and ServiceODR Backlog Information
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. Our backlog includes projects that have a written award, a letter of intent, a notice to proceed or an agreed upon work order to perform work on mutually accepted terms and conditions. Additionally, the difference between our backlog and remaining performance obligations is due to the portion of unexercised contract options that are excluded, under certain contract types, from our remaining performance obligations as these contracts can be canceled for convenience at any time by us or the customer without considerable cost incurred by the customer. Additional information related to our remaining performance obligations is provided in Note 16 — Remaining Performance Obligations in the accompanying notes to our condensed consolidated financial statements.
Given the multi-year duration of many of our contracts, revenue from backlog is expected to be earned over a period that will extend beyond one year. Many of our contracts contain provisions that allow the contract to be canceled at any time; however, if this occurs, we can generally recover costs incurred up to the date of cancellation.
ConstructionOur GCR backlog as of June 30, 20202021 was $408.8$378.9 million compared to $504.2$393.5 million at December 31, 2019.2020. In addition, ServiceODR backlog as of June 30, 20202021 was $61.8$60.6 million compared to $57.0$50.9 million at December 31, 2019 as a result of incremental Service sales generated from the Company’s investment in Service sales staff over the past few years.2020. Of the total backlog at June 30, 2020,2021, we expect to recognize approximately $275.9$211.0 million by the end of 2020.2021.
Seasonality, Cyclicality and Quarterly Trends
Severe weather can impact our operations. In the northern climates where we operate, and to a lesser extent the southern climates as well, severe winters can slow our productivity on construction projects, which shifts revenue and gross profit recognition to a later period. Our maintenance operations may also be impacted by mild or severe weather. Mild weather tends to reduce demand for our maintenance services, whereas severe weather may increase the demand for our maintenance and spot services. Our operations also experience mild cyclicality, as building owners typically work through maintenance and capital projects at an increased level during the third and fourth calendar quarters of each year.
Effect of Inflation and Tariffs
The prices of products such as steel, pipe, copper and equipment from manufacturers are subject to fluctuation and the imposition of or increases in tariffs. While itincreases. It is difficult to accurately measure the impact of inflation, tariffs and tariffsprice escalation due to the imprecise nature of the estimates required, we believerequired. However, these effects of inflation, if any, onare, at times, material to our results of operations and financial conditioncondition. During the first half of 2021, we have been immaterial.experienced higher cost of materials on specific projects and delays in our supply chain for equipment and service vehicles from the manufacturers, and we expect these higher costs and delays in our supply chain to persist through 2021. When appropriate, we include cost escalation factors into our bids and proposals.proposals as well as limit the acceptance time of our bid. In addition, we are often able to mitigate the impact of future price increases by entering into fixed price purchase orders for materials and equipment and subcontracts on our projects. Notwithstanding these efforts, if we experience significant disruptions to our supply chain, we may need to delay certain projects that would otherwise be accretive to our business and this may also impact the conversion rate of our current backlog into revenue.
Liquidity and Capital Resources
Cash Flows

Our liquidity needs relate primarily to the provision of working capital (defined as current assets less current liabilities) to support operations, funding of capital expenditures, and investment in strategic opportunities. Historically, liquidity has been provided by operating activities and borrowings from commercial banks and institutional lenders.

Our cash flows are primarily impacted from period to period by fluctuations in working capital. Factors such as our contract mix, commercial terms, days sales outstanding (“DSO”) and delays in the start of projects may impact our working capital. In line with industry practice, we accumulate costs during a given month then bill those costs in the current month for many of our contracts. While labor costs associated with these contracts are paid weekly and salary costs associated with the contracts are paid bi-weekly, certain subcontractor costs are generally not paid until we receive payment from our customers (contractual “pay-if-paid” terms). We have not historically experienced a large volume of write-offs related to our receivables and contract assets. We regularly assess our receivables for collectability and provide allowances for doubtful accounts where appropriate. We believe that our reserves for doubtful accounts are appropriate as of June 30, 20202021 and December 31, 2019,2020, but adverse changes in the economic environment may impact certain of our customers’ ability to access capital and compensate us for our services, as well as impact project activity for the foreseeable future.
The Company's existing current backlog is projected to provide substantial coverage of forecasted constructionGCR revenue for one year from the date of the financial statement issuance. Our current cash balance, together with cash we expect to generate from future operations (inclusive of actions we are taking to reduce costs and spending across our organization, in response to the COVID-19 pandemic) along with borrowings available under our 2019 Refinancing Agreement and 2019 ABL Credit Agreement, isWintrust Loans, are expected to be sufficient to finance our short- and long-term capital requirements (or meet working capital requirements) for the next twelve months. In addition to the future operating cash flows of the Company, along with its existing borrowing availability and access to financial markets, the Company believes it will be able to meet any working capital and future operating requirements, and capital investment forecast opportunities for the next twelve months. If current economic conditions decline materially from information presently available or if project shutdowns recur in the fourth quarter of 2020 or the first quarter of 2021, the Company could be unable to meet its financial covenants, which would cause an event of default thereby classifying its debt as current. If the lenders were to call the debt, the Company might not have the available working capital to satisfy its outstanding debt obligations.

Cash Flows (Used in) Provided by (Used in) Operating Activities
Cash flows used in operating activities were $24.6 million for the six months ended June 30, 2021 compared to cash flows provided by operating activities of $22.5 million for the six months ended June 30, 2020. For the six months ended June 30, 2021, cash used in operating activities were negatively impacted by an $8.9 million increase in accounts receivable, a $7.5 million decrease in contract liabilities, a $5.5 million decrease in accrued expenses and other current liabilities, and a $3.7 million increase in contract assets.
Cash flows provided by operating activities were $22.5 million for the six months ended June 30, 2020 compared to cash flows used in operating activities of $15.7 million for the six months ended June 30, 2019.2020. For the six months ended June 30, 2020, the key components included cash inflows of $3.6 million related to our accounts receivable, $4.9 million related to our contract assets, $16.3 million for our contract liabilities shifting from an underbilled to an overbilled position consistent with our renewed focus on project cash flows and $9.4 million related to accrued expenses and other current liabilities. These cash inflows were offset by outflows of $19.5 million related to our accounts payable, including retainage.
Cash flows usedThe decrease in operating activitiescash flows during the six months ended June 30, 2021 compared to the six months ended June 30, 2020 were $15.7mostly attributable to the reduction of our net overbilling position, which resulted in a $32.3 million cash outflow period-over-period, and a $12.5 million period-over-period cash outflow related to the change in accounts receivable. The decrease in our overbilled position was due to the reduction in GCR revenue and the timing of contract billings and the recognition of contract revenue. In addition, the reduction in accounts receivable was due to the timing of billings and collections.
Non-cash charges for depreciation and amortization were $3.0 million for the six months ended June 30, 2019. For the six months ended June 30, 2019, our cash usage in operating activities was significantly impacted by a $5.7 million increase in accounts receivable, a $4.7 million decrease in accounts payable, a $4.5 million decrease in contract assets, a $4.7 million increase in contract liabilities. The accounts receivable increase resulted primarily from our lower revenue volume2021 and billing during the second quarter of 2019 in comparison to stronger revenue and billings for the fourth quarter of 2018. The reduction in accounts payable is consistent with our decrease in accounts receivable and attributable to our second quarter 2019 revenue volume decrease, as well as tighter management of our payable balances. Our decrease of $9.2 million in net contract assets resulted primarily from the combination of 2019 unbilled costs incurred on a Southern California region Construction project on which a claim and change orders are pending, additional work performed on a previously overbilled Florida Construction project that is nearing completion, the final settlement of a significant Michigan region project, and the effects of our second quarter 2019 overall revenue reduction as compared to the fourth quarter of 2018. The significant decreases in other current assets and accrued expenses and other current liabilities are primarily attributable to the $30.0 million lawsuit settlement payments referenced in Note 14 to the accompanying condensed consolidated financial statements. The settlement of this matter was entirely covered by the Company's insurance carriers.
Non-cash charges for depreciation and amortization were $3.1 million for the six months ended June 30, 2020 and $2.9 million for the six months ended June 30, 2019.2020.
Cash Flows Used in Investing Activities

On February 24, 2021, LFS, LHLLC and the direct and indirect subsidiaries of LFS from time to time included as parties to the agreement (the “Wintrust Guarantors”) entered into a Credit Agreement (the “Credit Agreement”) by and among the LFS, LHLLC, Wintrust Guarantors, the lenders party thereto from time to time, Wheaton Bank & Trust Company, N.A., a subsidiary of Wintrust Financial Corporation (collectively, “Wintrust”), as administrative agent and L/C issuer, Bank of the West as documentation agent, M&T Bank as syndication agent, and Wintrust as lead arranger and sole book runner.

In accordance with the terms of the Credit Agreement, Lenders provide to LFS (i) a $30.0 million senior secured term loan (the “Wintrust Term Loan”); and (ii) a $25.0 million senior secured revolving credit facility with a $5.0 million sublimit for the issuance of letters of credit (the “Wintrust Revolving Loan” and, together with the Wintrust Term Loan, the “Wintrust Loans”). Proceeds of the Wintrust Loans were used to refinance certain existing indebtedness, finance working capital and other general corporate purposes and fund certain fees and expenses associated with the closing of the Wintrust Loans.

The Wintrust Revolving Loan bears interest, at the LFS’s option, at either LIBOR (with a 0.25% floor) plus 3.5% or a base rate (with a 3.0% floor) plus 0.50%, subject to a 50 basis point step-down based on the ratio between the senior debt of the Company and its subsidiaries to the EBITDA (earnings before interest, income taxes, depreciation and amortization) of the LFS and its subsidiaries for the most recently ended four fiscal quarters (the “Senior Leverage Ratio”). The Wintrust Term Loan bears interest, at LFS’s option, at either LIBOR (with a 0.25% floor) plus 4.0% or a base rate (with a 3.0% floor) plus 1.00%, subject to a 50 (for LIBOR) or 75 (for base rate) basis point step-down based on the Senior Leverage Ratio.

LFS is required to make principal payments on the Wintrust Term Loan in $0.5 million installments on the last business day of each month commencing on March 31, 2021 with a final payment of all principal and interest not sooner paid on the Wintrust Term Loan due and payable on February 24, 2026. The Wintrust Revolving Loan will mature and become due and payable by LFS on February 24, 2026.

The Wintrust Loans are secured by (i) a valid, perfected and enforceable lien of the administrative agent on the ownership interests held by each of LFS and Wintrust Guarantors in their respective subsidiaries; and (ii) a valid, perfected and enforceable lien of the administrative agent on each of LFS and Wintrust Guarantors’ personal property, fixtures and real estate, subject to certain exceptions and limitations. Additionally, the re-payment of the Wintrust Loans shall be jointly and severally guaranteed by each Wintrust Guarantor.

The Credit Agreement contains representations and warranties, covenants and events of default that are customary for facilities of this type, as more particularly described in the Credit Agreement. The Wintrust Loans also contain three financial maintenance covenants, including (i) a requirement to have as of the last day of each quarter for the senior leverage ratio of the Company and its subsidiaries not to exceed an amount beginning at 2.25 to 1.00 through December 31, 2021, and stepping down to 2.00 to 1.00 at all times thereafter, (ii) a fixed charge coverage ratio of not less than 1.20 to 1.00 as of the last day of each fiscal quarter commencing with the fiscal quarter ending March 31, 2021, and (iii) no unfinanced capital expenditures, except for unfinanced capital expenditures in the ordinary course of business not exceeding in the aggregate $4.0 million during any fiscal year; and no default or event of default (as defined by the agreement) has occurred and is continuing, 50% of any portion of this annual limit, if not expended in the fiscal year for which it is permitted, may be carried over for expenditure in the next following fiscal year as stipulated by the agreement. LFS and its affiliates maintain various commercial and service relationships with certain members of the syndicate and their affiliates in the ordinary course of business. As of June 30, 2021, the Company was in compliance with all financial maintenance covenants as required by the Wintrust Loans.

Cash Flow Summary
Management continues to devote additional resources to its billing and collection efforts which has resulted in positive cash flow from operating activities forduring the six months ended June 30, 2020.2021. Management continues to expect that growth in its serviceODR business, which is less sensitive to the cash flow issues presented by large constructionGCR projects, will positively impact our cash flow trends.
Provided that the Company’s lenders continue to provide working capital funding, we believe based on the Company's current reforecast that our current cash and cash equivalents of $28.8$27.7 million as of June 30, 2020,2021, cash payments to be received from existing and new customers, and availability of borrowing under the revolving line of credit under our 2019 Refinancing AgreementWintrust Loans (pursuant to which we had $14.0$21.6 million of availability as of June 30, 2020)2021) will be sufficient to meet our working capital and capital expenditure requirements for at least the next 12 months. See Note 1 - Organization and Plan of Business Operations.

Surety Bonding
In connection with our business, we are occasionally required to provide various types of surety bonds that provide an additional measure of security to our customers for our performance under certain government and private sector contracts. Our ability to obtain surety bonds depends upon our capitalization, working capital, past performance, management expertise and external factors, including the capacity of the overall surety market. Surety companies consider such factors in light of the amount of our backlog that we have currently bonded and their current underwriting standards, which may change from time-to-time. The bonds we provide typically reflect the contract value. As of June 30, 20202021 and December 31, 2019,2020, the Company had approximately $128.6$265.3 million and $116.0$79.4 million in surety bonds outstanding, respectively. We believe that our $700.0 million bonding capacity provides us with a significant competitive advantage relative to many of our competitors which have limited bonding capacity.

Insurance and Self-Insurance
We purchase workers’ compensation and general liability insurance under policies with per-incident deductibles of $250,000 per occurrence. Losses incurred over primary policy limits are covered by umbrella and excess policies up to specified limits with multiple excess insurers. We accrue for the unfunded portion of costs for both reported claims and claims incurred but not reported. The liability for unfunded reported claims and future claims is reflected on the Condensed Consolidated Balance Sheets as current and non-current liabilities. The liability is computed by determining a reserve for each reported claim on a case-by-case basis based on the nature of the claim and historical loss experience for similar claims plus an allowance for the cost of incurred but not reported claims. The current portion of the liability is included in accrued expenses and other current liabilities on the Condensed Consolidated Balance Sheets. The non-current portion of the liability is included in other long-term liabilities on the Condensed Consolidated Balance Sheets.
We are self-insured related to medical and dental claims under policies with annual per-claimant and annual aggregate stop-loss limits. We accrue for the unfunded portion of costs for both reported claims and claims incurred but not reported. The liability for unfunded reported claims and future claims is reflected on the Condensed Consolidated Balance Sheets as a current liability in accrued expenses and other current liabilities.
The components of the self-insurance liability are reflected below as of June 30, 20202021 and December 31, 2019:2020:

Multiemployer Pension Plans
We participate in approximately 40 multiemployer pension plans (“MEPPs”) that provide retirement benefits to certain union employees in accordance with various collective bargaining agreements (“CBAs”). As one of many participating employers in these MEPPs, we are responsible with the other participating employers for any plan underfunding. Our contributions to a particular

MEPP are established by the applicable CBAs; however, required contributions may increase based on the funded status of an MEPP and legal requirements of the Pension Protection Act of 2006 (the “PPA”), which requires substantially underfunded MEPPs to implement a funding improvement plan (“FIP”) or a rehabilitation plan (“RP”) to improve their funded status. Factors that could impact funded status of an MEPP include, without limitation, investment performance, changes in the participant demographics, decline in the number of contributing employers, changes in actuarial assumptions and the utilization of extended amortization provisions. Assets contributed to the MEPPs by us may be used to provide benefits to employees of other participating employers. If a participating employer stops contributing to an MEPP, the unfunded obligations of the MEPP may be borne by the remaining participating employers.

Table of Contents

An FIP or RP requires a particular MEPP to adopt measures to correct its underfunding status. These measures may include, but are not limited to an increase in a company’s contribution rate as a signatory to the applicable CBA, or changes to the benefits paid to retirees. In addition, the PPA requires that a 5.0% surcharge be levied on employer contributions for the first year commencing shortly after the date the employer receives notice that the MEPP is in critical status and a 10.0% surcharge on each succeeding year until a CBA is in place with terms and conditions consistent with the RP.
We could also be obligated to make payments to MEPPs if we either cease to have an obligation to contribute to the MEPP or significantly reduce our contributions to the MEPP because we reduce the number of employees who are covered by the relevant MEPP for various reasons, including, but not limited to, layoffs or closure of a subsidiary assuming the MEPP has unfunded vested benefits. The amount of such payments (known as a complete or partial withdrawal liability) would equal our proportionate share of the MEPPs’ unfunded vested benefits. We believe that certain of the MEPPs in which we participate may have unfunded vested benefits. Due to uncertainty regarding future factors that could trigger withdrawal liability, we are unable to determine (a) the amount and timing of any future withdrawal liability, if any, and (b) whether our participation in these MEPPs could have a material adverse impact on our financial condition, results of operations or liquidity.
Item 3. Quantitative and Qualitative Disclosures About Market Risk
We are a smaller reporting company as defined in Rule 12b-2 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”); therefore, pursuant to Item 301(c) of Regulation S-K, we are not required to provide the information required by this Item.
Item 4. Controls and Procedures
Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures
Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures, as defined in Rule 13a-15(e) under the Exchange Act. Based on that evaluation as of June 30, 2020,2021, our Chief Executive Officer and Chief Financial Officer concluded that our Company’s disclosure controls and procedures were effective.
Changes in Internal Control over Financial Reporting
There waswere no changechanges in our internal control over financial reporting identified in connection with the evaluation required by Rule 13a-15(d) and 15d-15(d) of the Exchange Act that occurred during the period covered by this Quarterly Report on Form 10-Q that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
As a result of the COVID-19 pandemic, certain employees began working remotely in March 2020 and continue to do so. Notwithstanding these changes to the working environment, we have not identified any material changes in our internal control over financial reporting. We will continue to monitor and assess the COVID-19 situation to determine any potential impact on the design and operating effectiveness of our internal controls over financial reporting.
Inherent Limitations on Effectiveness of Controls
In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, cannot provide absolute assurance of achieving the desired control objectives. Our management recognizes that any control system, no matter how well designed and operated, is based upon certain judgments and assumptions and cannot provide absolute assurance that its objectives will be met. Similarly, an evaluation of controls cannot provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, have been detected.
