LIMBACH HOLDINGS, INC.

Notes to Condensed Consolidated Financial Statements (Unaudited)

Note 1 – Organization and Plan of Business Operations

Limbach Holdings, Inc. (the “Company,” “we” or “us”), is a Delaware corporation headquartered in Pittsburgh, Pennsylvania that was formed on July 20, 2016, as a result of a business combination with Limbach Holdings LLC (“LHLLC”). The Company’s condensed consolidated financial statements include the accounts of Limbach Holdings, Inc. and its wholly-owned subsidiaries, including LHLLC, Limbach Facility Services LLC, Limbach Company LLC, Limbach Company LP, Harper Limbach LLC, and Harper Limbach Construction LLC.

As of January 1, 2021, the Company renamed its existing 2 reportable segments to reflect our 2 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”). The Company operates in 2 segments that are based on the relationship with its customer, (i) GCR, in which the Company generally manages new construction or renovation projects that involve primarily heating, ventilation, and air conditioning (“HVAC”), plumbing, or electrical services awarded to the Company by general contractors or construction managers, and (ii) ODR, in which the Company provides maintenance or service primarily on HVAC, plumbing or electrical systems, building controls and 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.

The Company's customers operate in diverse industries including, but not limited to, healthcare, life sciences, data centers, industrial and light manufacturing, entertainment, education and government. The Company operates primarily in the Northeast, Mid-Atlantic, Southeast, Midwest, and Southwestern regions of the United States.

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, restrictions 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 abated over time, but remain applicable to Limbach's operations in various ways, often varying by state. In some instances, these orders continued to affect certain projects in our GCR and ODR segments into the 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 fiscal 2020 and into 2021, and most of the projects that were in progress at the time shutdowns commenced ~~have~~were restarted. The Company’s branches are expecting building owners to maintain or retrofit current facilities in lieu of funding larger capital projects as the effects of the pandemic remain ongoing and uncertain.

During fiscal 2020 and through the ~~first~~second quarter of 2021, the Company continued to take several actions to combat the adverse impacts that the COVID-19 outbreak had 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 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

• Temporarily suspended substantially all discretionary, non-essential expenditures, including but not limited to, auto allowances, deferral of rent ranging between 1 and 3 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.

Table of Contents

During the month of July 2020, with the substantial restart and return of project and service work, the 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. During the remainder of 2020 and into 2021, the Company reinstituted limited travel and in-person meetings, along with

~~Table of Contents~~

encouraging employees to return to the office, 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 changing 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 ~~quarter~~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 its business and to protect the safety of its employees, and the Company continues to emphasize wearing of masks, more frequent washing of hands and tools, social distancing, and work protocols. Limbach's COVID-19 Policy is 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 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.

Basis of Presentation

Condensed Consolidated Financial Statements

The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with instructions to the Quarterly Report on Form 10-Q and Rule 8-03 of Regulation S-X for smaller reporting companies. Consequently, certain information and note disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) have been condensed or omitted pursuant to those rules and regulations, although the Company believes that the disclosures made are adequate to make the information not misleading. Readers of this report should refer to the consolidated financial statements and the notes thereto included in our most recent Annual Report on Form 10-K filed with the Securities and Exchange Commission (the “SEC”) on March 25, 2021.

Unaudited Interim Financial Information

The accompanying interim Condensed Consolidated Balance Sheets, Condensed Consolidated Statements of Operations, Condensed Consolidated Statements of Stockholders’ Equity and Condensed Consolidated Statements of Cash Flows for the periods presented are unaudited. Also, within the notes to the Condensed Consolidated Financial Statements, we have included unaudited information for these interim periods. These unaudited interim Condensed Consolidated Financial Statements have been prepared in accordance with GAAP. In our opinion, the accompanying unaudited Condensed Consolidated Financial Statements contain all normal and recurring adjustments necessary for a fair statement of the Company’s financial position as of ~~March 31,~~June 30, 2021, its results of operations and its cash flows for the three and six months ended ~~March 31,~~June 30, 2021. The results for the three and six months ended ~~March 31,~~June 30, 2021 are not necessarily indicative of the results to be expected for the year ending December 31, 2021.

The Condensed Consolidated Balance Sheet as of December 31, 2020 was derived from our audited financial statements included in our Annual Report on Form 10-K filed with the SEC on March 25, 2021, but is presented as condensed and does not contain all of the footnote disclosures from the annual financial statements.

Note 3 – Accounting Standards

Recently Adopted Accounting Standards

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. The adoption of this pronouncement did not have a material impact on our condensed consolidated financial statements or presentation thereof.

Also 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 the Codification, and makes other improvements and technical corrections to the Codification. The amendments in Sections B and C of this amendment are effective for annual periods beginning after December 15, 2020, for public business entities, with early adoption permitted. The adoption of this pronouncement did not have a material impact on our condensed consolidated financial statements or presentation thereof.

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.

The FASB has issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting in March 2020. This new guidance provides optional expedients for a 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.

Table of Contents

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 affected by the discounting transition. The amendments in this update are effective for all entities as of March 12, 2020 through December 31, 2022. The Company is currently evaluating the impact of adopting the reference rate reform guidance (both ASU 2020-04 and ASU 2021-01) on its condensed consolidated financial 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.

Retainage receivable represents amounts invoiced to customers where payments have been partially withheld, typically 10%, pending the completion of certain milestones, satisfaction of other contractual conditions or the completion of the project. Retainage agreements vary from project to project and balances could be outstanding for several months or years depending on a number of circumstances such as contract-specific terms, project performance and other variables that may arise as the Company makes progress towards completion.

Table of Contents

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 ~~$40.8~~$40.1 million and $33.6 million as of ~~March 31,~~June 30, 2021 and December 31, 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.

Contract liabilities include billings in excess of costs and estimated earnings and provisions for losses. The components of the contract liability balances as of the respective dates were as follows:


(in thousands)	(in thousands)	March 31, 2021		December 31, 2020		Change		(in thousands)	June 30, 2021		December 31, 2020		Change

~~Table of Contents~~

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.

The net overbilling position for contracts in process consist of the following:

We recorded revisions in our contract estimates for certain GCR projects. For projects having revisions with a material gross profit impact of $0.25 million or more, this resulted in: (1) gross profit write downs on 2 GCR segment projects of $0.7 million for the three months ended March 31, 2021, 1 of which was within the Southern California region for a total of $0.2 million and the other was within the Eastern Pennsylvania region for a total of $0.5 million, and (2) gross profit write ups of $0.7 million on 2 GCR segment projects for the three months ended March 31, 2021.

2019 Refinancing Agreement

On April 12, 2019 (the “Refinancing Closing Date”), Limbach Facility Services LLC (“LFS”) entered into a financing agreement (the “2019 Refinancing Agreement”) with the lenders thereto and Cortland Capital Market Services LLC, as collateral agent and administrative agent and CB Agent Services LLC, as origination agent (“CB”). The 2019 Refinancing Agreement consisted of (i) a $40.0 million term loan (the “2019 Refinancing Term Loan”) and (ii) a new $25.0 million multi-draw delayed draw term loan (the “2019 Delayed Draw Term Loan” and, collectively with the 2019 Refinancing Term Loan, the “2019 Term Loans”). Proceeds from the 2019 Refinancing Term Loan were used to repay the then existing Credit Agreement, to pay related fees and expenses thereof and to fund working capital of the 2019 Refinancing Borrowers (defined below). Management intended for proceeds of the 2019 Delayed Draw Term Loan to be used to fund permitted acquisitions under the 2019 Refinancing Agreement and related fees and expenses in connection therewith.

LFS and each of its subsidiaries were borrowers (the “2019 Refinancing Borrowers”) under the 2019 Refinancing Agreement. In addition, the 2019 Refinancing Agreement was guaranteed by the Company and LHLLC (each, a ~~“Guarantor”~~“2019 Refinancing Guarantor”, and together with the 2019 Refinancing Borrowers, the “Loan Parties”).

The 2019 Refinancing Agreement was secured by a first-priority lien on the real property of the Loan Parties and a second-priority lien on substantially all other assets of the Loan Parties, behind the 2019 ABL Credit Agreement (as defined below). The respective lien priorities of the 2019 Refinancing Agreement and the 2019 ABL Credit Agreement were governed by an intercreditor agreement.

At February 24, 2021 (the 2021 refinancing date) and ~~March 31,~~June 30, 2020, the interest rate in effect on the 2019 Refinancing Term Loan was 13.00%.

There was an unused line fee of 2.0% per annum on the undrawn portion of the 2019 Delayed Draw Term Loan, and there iswas a make-whole premium on prepayments made prior to the 19-month anniversary of the Refinancing Closing Date. This make-whole provision guaranteed that the Company would pay no less than 18 months’ applicable interest to the lenders under the 2019 Refinancing Agreement.

The 2019 Refinancing Agreement contained representations and warranties, and covenants which were customary for debt facilities of this type. Unless the Required Lenders (as defined in the 2019 Refinancing Agreement) otherwise consented in writing, the covenants limited the ability of the Company and its restricted subsidiaries to, among other things, (i) incur additional indebtedness or issue preferred stock, (ii) pay dividends or make distributions to the Company’s stockholders, (iii) purchase or redeem the Company’s equity interests, (iv) make investments, (v) create liens on their assets, (vi) enter into transactions with the Company’s affiliates, (vii) sell assets and (viii) merge or consolidate with, or dispose of substantially all of the Company’s assets to, other companies.

In addition, the 2019 Refinancing Agreement included customary events of default and other provisions that could require all amounts due thereunder to become immediately due and payable, either automatically or at the option of the lenders, if the Company failed to comply with the terms of the 2019 Refinancing Agreement or if other customary events occur.

2019 Refinancing Agreement - CB Warrants

In connection with the 2019 Refinancing Agreement, on the Refinancing Closing Date, the Company issued to CB and the other lenders under the 2019 Refinancing Agreement warrants (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. The actual number of shares of common stock into which the CB Warrants were exercisable at any given time were equal to: (i) the product of (x) the number of shares equal to 2% of the Company’s issued and outstanding shares of common stock on the Refinancing Closing Date on a fully diluted basis and (y) the percentage of the total 2019 Delayed Draw Term Loan made as of the exercise date, minus (ii) the number of shares previously issued under the CB Warrants. As of the Refinancing Closing Date through February 24, 2021, 0 amounts had been drawn on the 2019 Delayed Draw Term Loan, so 0 portion of the CB Warrants ~~was~~were exercisable. The CB Warrants were to be exercised for cash or on a “cashless basis,” subject to certain adjustments, at any time after the 2019 Refinancing Closing Date until the expiration of such warrant at 5:00 p.m., New York time, on the earlier of (i) the five (5) year anniversary of the 2019 Refinancing Closing Date, or (ii) the liquidation of the Company.

Accounting for the 2019 Term Loans and CB Warrants

~~Table of Contents~~

The CB Warrants represented a freestanding financial instrument that was classified as a liability because the CB Warrants met the definition of a derivative instrument that does not meet the equity scope exception (i.e., the CB Warrants were 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 represented a non-credit related embedded feature that provides for net settlement. Both the CB Warrants liability and the embedded derivative liability were 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 was included in other long-term liabilities. The Company remeasured the fair value of the CB Warrants liability as of December 31, 2020 and February 24, 2021 prior to the refinancing date and recorded any adjustments as other income (expense). At both February 24, 2021 and December 31, 2020, the CB Warrants liability was $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 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 ~~March 31,~~June 30, 2021 as the CB Warrants liability was extinguished as part of the debt refinancing on February 24, 2021. For the three and ~~March 31,~~six months ended June 30, 2020, the Company recorded other income of ~~$14 thousand~~$0.1 million and ~~$0.2~~other expense of $0.1 million ~~respectively,~~ to reflect the change in ~~fair value of~~ the CB Warrants liability.

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 $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 were being amortized into interest expense over the term of the 2019 Term Loans using the effective interest 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 ~~both~~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 ~~March 31,~~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 ~~2020, and recorded an additional~~embedded derivative debt discounts of $0.1 million and ~~$0.4~~$0.2 million for the three and six months ended June 30, 2020, 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 ~~March 31,~~June 30, 2021 as the debt issuance costs were extinguished as part of the debt refinancing on February 24, 2021. For the three and ~~March 31,~~six months ended June 30, 2020, ~~respectively.~~ the Company recorded an additional $0.4 million and $0.7 million of interest expense, respectively, for the amortization of the debt issuance costs related to the 2019 Refinancing Term Loan.

On May 24, 2020 the Board of Directors approved 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. The amendments were approved by the Company's stockholders at the Annual Meeting held on July 14, 2020.

On March 9, 2021, the Board of Directors approved 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 600,000, for a total of 2,250,000 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. The amendments were approved by the Company's stockholders at the Annual Meeting held on June 16, 2021.

See Note 17 - Management Incentive Plans for RSUs granted, vested, forfeited and remaining unvested.

Upon approval 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 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 10 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. In 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 and December 31, 2020 offering periods, respectively. ~~Stock compensation expense related to the ESPP was $17 thousand for the three months ended March 31, 2021. As of March 31, 2020, 0 shares had been issued under the ESPP.~~

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 of 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 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

~~Table of Contents~~

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.

Table of Contents

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 values due to the variable rate on such debt. As of February 24, 2021 and December 31, 2020, the Company determined that the fair value of its 2019 Revolving Agreement term loan was $39.0 million. As of ~~March 31,~~June 30, 2021, the Company determined that the fair value of its 2021 Wintrust Term Loan was ~~$29.5~~$28.0 million. There were 0 outstanding borrowings on the Company's 2019 ABL Credit Agreement revolver at February 24, 2021 and December 31, 2020. Such fair values were determined using discounted estimated future cash flows using level 3 inputs.

(1) For the ~~quarter~~three and six months ended ~~March 31,~~June 30, 2021 and 2020, certain PRSU and MRSU awards were not included in the computation of diluted loss per share because the performance and market conditions were not satisfied during the periods and would not be satisfied if the reporting date was at the end of the contingency period.

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.

Table of Contents

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 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 ~~March 31,~~June 30, 2021, respectively. For the three and ~~March 31,~~six months ended June 30, 2020, ~~was 31.2%~~the Company had an income tax rate of 27.4% and ~~92.4%~~14.1%, respectively.

NaN valuation allowance was required as of ~~March 31,~~June 30, 2021 or December 31, 2020.

The Company had previously recorded a liability for unrecognized tax benefits (“UTB”) related to tax positions taken on its various income tax returns in open tax periods. If recognized, a portion of unrecognized tax benefits would favorably impact the effective tax rate that is reported in future periods. The Company filed to change an improper tax method of accounting in the fourth quarter of 2020 related to the UTB that affords the Company IRS audit protection in past periods. Therefore, the total unrecognized tax benefits were reduced in the fourth quarter of 2020.

The following is a reconciliation of the beginning and ending unrecognized tax 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 2 distinct operating 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 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.

~~Table of Contents~~

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 ~~Corporate~~corporate office operating expenses. In accordance with ASC Topic 280 – Segment Reporting, the Company has elected to aggregate all of the construction activity into 1 GCR reportable segment and all of the service branches into 1 ODR reportable segment. All transactions between segments are eliminated in consolidation. Our corporate department provides general and administrative support services to our 2 operating segments. The CODM allocates costs between segments for selling, general and administrative and depreciation expense.

All of the Company’s identifiable assets are located in the United States, which is where the Company is domiciled. Interest expense is not allocated to segments because of the corporate management of debt service including interest.

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.

Note 15 – Commitments and Contingencies

Legal. The Company is continually engaged in administrative proceedings, arbitrations, and litigation with owners, general contractors, suppliers, and other unrelated parties, all arising in the ordinary courses of business. In the opinion of the Company’s management, the results of these actions will not have a material adverse effect on the financial position, results of operations, or cash flows of the Company.

On November 13, 2019, claimant, Lanzo Trenchless Technologies, Inc. - North, filed a Demand for Arbitration in the state of Michigan against the Company's wholly-owned subsidiary, Limbach Company LLC. The demand seeks damages in excess of $0.4 million based upon the allegation that Limbach breached a construction contract by improperly terminating Lanzo’s subcontract, and for withholding payment from Lanzo based upon deficient performance. Limbach has asserted a counterclaim seeking damages caused by Lanzo’s deficient performance. ~~A binding arbitration proceeding is scheduled for July of 2021.~~Lanzo has recently abandoned its claims and the parties are attempting to negotiate a consent judgement in Limbach's favor that will result in the matter being concluded.

On January 23, 2020, plaintiff, Bernards Bros. Inc., filed a complaint against Limbach Holdings, Inc. in Superior Court of the State of California for the County of Los Angeles against Limbach Holdings, Inc. The complaint alleges that our Southern California operations refused to honor a proposal made to Bernards to act as a subcontractor on a construction project, and that, as a result of the wrongful failure to honor the proposal, Bernards suffered damages in excess of $3.0 million, including alleged increased costs for hiring a different subcontractor to perform the work. The Company is vigorously defending the ~~suit, which~~suit. A non-binding mediation is scheduled for August 19, 2021 and trial is currently ~~set for trial~~expected to take place in February 2022.

On April 17, 2020, plaintiff, LA Excavating, Inc., filed a complaint against our wholly-owned subsidiary, Limbach Company LP, and several other parties, in Superior Court of the State of California, for the County of Los Angeles. The complaint seeks damages of approximately $1.0 million for alleged failure to pay contract balances and extra work ordered by Limbach, as well as seeks to enforce payment obligations under payment and stop notice release bonds. The Company disputes the allegations and intends to vigorously defend the suit, which is currently set for trial in November of 2021.

In July of 2020, plaintiff, Kimball Construction Co., Inc., filed a complaint against our wholly-owned subsidiary, Limbach Company LLC in circuit Court for Montgomery County, Maryland. The complaint seeks damages of approximately $1.7 million for alleged failure to pay contract balances and extra work, as well as to enforce payment obligations under a payment bond issued by Limbach's surety provider. The Company ~~disputes the allegations~~ and ~~intends to vigorously defend~~Kimball have reached a cooperative resolution of these claims, which resulted in a Stipulation of Dismissal of the suit ~~which is currently set for trial to take place sometime in the second quarter~~on or about June 21, 2021.

Table of ~~2021.~~Contents

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 ~~March 31,~~June 30, 2021, the Company had approximately ~~$160.7~~$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

~~Table of Contents~~

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 ~~March 31,~~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 ~~$393.6~~$378.9 million and ~~$37.4~~$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 GCR and ODR segment contracts were $393.5 million and $35.7 million, respectively.

We estimate that ~~56%~~44% and ~~94%~~62% of our GCR and ODR segment remaining performance obligations as of ~~March 31,~~June 30, 2021, respectively, will be recognized as revenue during 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 ODR 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 ~~1,650,000~~2,250,000 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.

Service-Based Awards

During the first ~~three~~six months of 2021, the Company granted ~~118,232~~120,899 service-based RSUs to its executives, certain employees, and non-employee directors under the Omnibus Incentive Plan.

Performance-Based Awards

During the first ~~three~~six months of 2021, the Company granted ~~180,034~~185,367 performance-based RSUs (“PRSUs”) to its executives and certain employees under the Omnibus Incentive Plan. The Company will recognize stock-based compensation expense for these awards over the vesting period based on the projected probability of achievement of certain performance conditions as of the end of each reporting period during the performance period and may periodically adjust the recognition of such expense, as necessary, in response to any changes in the Company’s forecasts with respect to the performance conditions. For the three and six months ended ~~March 31,~~June 30, 2021, the Company recognized $0.2 million and $0.4 million, respectively, of stock-based compensation expense related to outstanding PRSUs. For the three and six months ended ~~March 31,~~June 30, 2020, the Company ~~did 0t recognize any~~recognized $0.1 million of stock-based compensation expense related to ~~any~~ outstanding PRSUs.

Market-Based Awards

On September 4, 2020, the Compensation Committee (the “Committee”) of the Board of Directors of the Company approved amendments to certain restricted stock units initially awarded on August 30, 2017 by the Company to certain employees. Pursuant to the amendment adopted on September 4, 2020, the measurement period was extended to July 16, 2022. In addition to the market performance-based vesting condition, the vesting of such restricted stock unit is subject to continued employment from August 1, 2017 through the later of July 31, 2019 or the date on which the Committee certifies the achievement of the performance goal. The Company has accounted for this amendment as a Type I modification and will recognize approximately $0.2 million of incremental stock-based compensation expense over 1.26 years based on an updated Monte Carlo simulation model.

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, 2020 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 integrated building systems solutions firm whose expertise is in the design, modular prefabrication, installation, management and maintenance of heating, ventilation, and air conditioning (“HVAC”), mechanical, electrical, plumbing and control systems. Our market sectors primarily include the following: healthcare, life sciences, data centers, industrial and light manufacturing, entertainment, education and government. Our customers are primarily located throughout Florida, California, Massachusetts, New Jersey, Pennsylvania, Delaware, Maryland, Washington, D.C., Virginia, West Virginia, Ohio and Michigan. As of January 1, 2021, the Company renamed its existing two reportable segments to reflect our 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”). The Company operates in two segments that are based on the relationship with its customer, (i) GCR, in which the Company generally manages 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) ODR, in which the Company provides maintenance or service primarily on HVAC, plumbing or electrical systems, building controls and 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.

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

Selling, general and administrative 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.

Table of Contents

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 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 loss on the sale of property and equipment and changes 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. 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 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 GCR work performed at branches into one GCR reportable segment and all of the ODR work performed at branches into one ODR 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 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 recorded revisions in our contract estimates for certain GCR ~~segment~~and ODR projects. For projects having revisions with a material gross profit impact of $0.25 million or more, this resulted in: (1) gross profit write downs on two GCR projects of $0.7 million for the three months ended March 31, 2021, one of which was within the Southern California region for a total of $0.2 million and the other was within the Eastern Pennsylvania region for a total of $0.5 million, and (2) gross profit write ups of $0.7 million on two GCR segment projects for the three months ended March 31, 2021. There were no material gross profit write ups or write downs of $0.25 million or more on ODR segment projects.

For the three months ended ~~March 31,~~June 30, 2021 and 2020, ~~we recorded revisions in our contract estimates for certain GCR segment projects.

Revenue for the six months ended June 30, 2021 decreased by $39.6 million compared to the revenue for the six months ended June 30, 2020. GCR revenue decreased by $43.1 million, or 20.0%, while ODR revenue increased by $3.5 million, or 5.9%. GCR segment revenue of $172.4 million decreased due to a planned decrease in the Southern California and Mid-Atlantic operating regions and other decreases in the Florida, Eastern Pennsylvania, Ohio, and Western Pennsylvania operating regions. These decreases were partially offset by revenue increases in the Michigan and New England operating regions largely due to the start of new projects and the continuation of work on existing projects. Ohio, Eastern Pennsylvania, Michigan, and New England regions' ODR revenue increased nearly offset by declines in ODR revenue in Florida and Mid-Atlantic. Maintenance contract revenue, a component of ODR revenue, increased by $0.4 million compared to the six months ended June 30, 2020.

Our gross profit for the six months ended June 30, 2021 decreased by $2.6 million compared to our gross profit for the six months ended June 30, 2020. GCR gross profit decreased $4.9 million, or 21.2%, largely due to lower revenue at slightly lower margins. ODR gross profit increased $2.3 million, or 14.8%, due to an increase in revenue at higher margins. The total gross profit percentage increased from 14.1% for the six months ended June 30, 2020 to 15.3% for the same period ended in 2021, mainly driven by the mix of higher margin ODR segment work.

For the six months ended June 30, 2021 and 2020, total net gross profit write-downs were $1.7 million and $3.4 million, respectively. For projects having a material gross profit impact of $0.25 million or more, we recorded gross profit write downs on eight GCR segment projects of $3.5 million and one ODR project for $0.3 million. Of the material GCR segment write downs, two projects were within the Michigan region for a total of $1.2 million, two projects were within the Eastern Pennsylvania region for $1.0 million, two projects were within the Southern California region for $0.8 million, one project was within the New England region for $0.3 million, and one project was within the Mid-Atlantic region for $0.3 million. We also materially wrote down one ODR segment project within the Eastern Pennsylvania region for $0.3 million. We also recorded material GCR segment gross profit write ups of $0.9 million on one GCR segment project in the Michigan region for $0.5 million and one project within the Ohio region for $0.4 million. For the six months ended June 30, 2020, we recorded material gross profit write downs on eight GCR projects and two gross profit write ups on GCR projects, for an aggregate revision of $5.2 million and $1.2 million, respectively.

Our payroll and travel and entertainment expenses remained flat during the six months ended June 30, 2021 compared to the six months ended June 30, 2020, as our investment in ODR expansion in 2021 was offset by severance expense incurred in 2020 due to our pandemic-driven operational reductions. Additionally, total SG&A as a percentage of revenues were 14.7% for the six months ended June 30, 2021 and 11.2% for the six months ended June 30, 2020.

GCR and ODR 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. Our GCR backlog as of ~~March 31,~~June 30, 2021 was ~~$393.6~~$378.9 million compared to $393.5 million at December 31, 2020. In addition, ODR backlog as of ~~March 31,~~June 30, 2021 was ~~$52.9~~$60.6 million compared to $50.9 million at December 31, 2020. Of the total backlog at ~~March 31,~~June 30, 2021, we expect to recognize approximately ~~$270.5~~$211.0 million by the end of 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 increases. It is difficult to accurately measure the impact of inflation, tariffs and price escalation due to the imprecise nature of the estimates required. However, these effects are, at times, material to our results of operations and financial condition. During the first half of 2021, we have 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 ~~March 31,~~June 30, 2021 and December 31, 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 GCR 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 along with borrowings available under our Wintrust 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.

The following table represents our summarized working capital information:

Cash Flows (Used in) Provided by Operating Activities

~~Table of Contents~~

Cash flows used in operating activities were ~~$17.4~~$24.6 million for the ~~three~~six months ended ~~March 31,~~June 30, 2021 compared to cash flows provided by operating activities of ~~$3.5~~$22.5 million for the ~~three~~six months ended ~~March 31,~~June 30, 2020. For the ~~three~~six months ended ~~March 31,~~June 30, 2021, cash used in operating activities ~~was significantly~~were negatively impacted by an $8.9 million increase in accounts receivable, a $7.5 million decrease in contract liabilities, ~~an $8.8~~a $5.5 million decrease in ~~accounts payable, including retainage, $2.0 million related to an increase in our contract assets reflecting the shift from an overbilled position to a neutral position,~~accrued expenses and other current liabilities, and a ~~$2.0~~$3.7 million increase in ~~other current~~contract assets. These cash outflows were offset by an increase of $2.6 million in accounts receivable and $2.0 million for the loss on early debt extinguishment in connection with our debt refinancing in late February 2021.

Cash flows provided by operating activities were ~~$3.5~~$22.5 million for the ~~three~~six months ended ~~March 31,~~June 30, 2020. For the ~~three~~six months ended ~~March 31,~~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, ~~$6.0~~$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 ~~$1.4~~$9.4 million related to accrued expenses and other current liabilities. These cash inflows were offset by outflows of ~~$7.3 million related to our accounts receivable and $5.8~~$19.5 million related to our accounts payable, including retainage.

The decrease in operating cash flows during the six months ended June 30, 2021 compared to the six months ended June 30, 2020 were mostly 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 ~~$1.5~~$3.0 million for the ~~three~~six months ended ~~March 31,~~June 30, 2021 and $3.1 million for the six months ended June 30, 2020.

Cash Flows ~~Provided by (Used in)~~Used in Investing Activities

Cash flows ~~provided by~~used in investing activities were ~~nearly breakeven~~$0.1 million and $0.6 million for the ~~three~~six months ended ~~March 31,~~June 30, 2021, ~~with $0.2~~and 2020, respectively. For the six months ended June 30, 2021, $0.5 million was used to purchase property and equipment, offset by ~~$0.2~~$0.4 million in proceeds from the sale of property and equipment. ~~Cash flows used in investing activities were $0.5 million for~~For the ~~three~~six months ended ~~March 31, 2020.~~ June 30, 2020, $0.7 million was used to purchase property and equipment, offset by $0.1 million in proceeds from the sale of property and equipment.

The majority of our cash used for investing activities in both periods was for capital additions pertaining to tools and equipment, computer software and hardware purchases, office furniture and office related leasehold improvements.

Cash Flows Provided by (Used in) Financing Activities

Cash flows provided by financing activities were ~~$12.4~~$10.3 million for the ~~three~~six months ended ~~March 31, 2021. Net~~June 30, 2021 compared to cash flows used in financing activities ~~was $0.7~~of $1.4 million for the ~~three~~six months ended ~~March 31,~~June 30, 2020. For the ~~three~~six months ended ~~March 31,~~June 30, 2021, we received proceeds from the following: $22.8 million, net of fees and expenses, in conjunction with our common stock offering in February 2021, $2.0 million from the exercise of warrants and $30.0 million in connection with the refinancing of the 2019 Refinancing Term Loan with the Wintrust Loans. These proceeds were offset by the $39.0 million payment in full of the 2019 Refinancing Term Loan and associated $1.4 million prepayment penalty and other extinguishment costs, ~~a $0.5~~$2.0 million of scheduled principal ~~payment~~payments on the Wintrust Term Loan, ~~$0.7~~$1.3 million for payments on finance leases, $0.4 million in taxes related to net share settlement of equity awards and $0.6 million for payments related to debt issuance costs related to the Wintrust Term Loan and ~~Revolver.~~Wintrust Revolving Loan.

For the ~~three~~six months ended ~~March 31,~~June 30, 2020, we ~~both~~ borrowed and repaid ~~a total of~~ $7.3 million on the 2019 Revolving Credit Facility and made ~~finance~~capital lease payments of ~~$0.7~~$1.3 million.

Debt and Other Obligations

The Company refinanced its 2019 Refinancing and ABL Credit Agreements on February 24, 2021, described below and therefore had no amounts outstanding under these agreements at ~~March 31,~~June 30, 2021. Accordingly, the Company recognized a loss on the early debt extinguishment of $2.0 million. This loss consisted of $2.6 million of debt issuance and debt discount costs, reversed $2.0 million of the CB warrant liability due to the warrants being cancelled on the refinancing date and paid a prepayment penalty of $1.4 million.

2019 Refinancing Agreement - CB Warrants

In connection with the 2019 Refinancing Agreement, on the Refinancing Closing Date, the Company issued to CB and the other lenders under the 2019 Refinancing Agreement warrants (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. The actual number of shares of common stock into which the CB Warrants ~~will be~~were exercisable at any given time ~~will be~~were equal to: (i) the product of (x) the number of shares equal to 2% of the Company’s issued and outstanding shares of common stock on the Refinancing Closing Date on a fully diluted basis and (y) the percentage of the total 2019 Delayed Draw Term Loan made as of the exercise date, minus (ii) the number of shares previously issued under the CB Warrants. As of the Refinancing Closing Date ~~and~~through February 24, 2021, no amounts had been drawn on the 2019 Delayed Draw Term Loan, so no portion of the CB Warrants ~~was~~were exercisable. The CB Warrants ~~may~~were to be exercised for cash or on a “cashless basis,” subject to certain adjustments, at any time after the 2019 Refinancing Closing Date until the expiration of such warrant at 5:00 p.m., New York time, on the earlier of (i) the five (5) year anniversary of the 2019 Refinancing Closing Date, or (ii) the liquidation of the Company.

Accounting for the 2019 Term Loans and CB Warrants

The CB Warrants represented a freestanding financial instrument that was classified as a liability because the CB Warrants met the definition of a derivative instrument that does not meet the equity scope exception (i.e., the CB Warrants ~~are~~were 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 represented a non-credit related embedded feature that provides for net settlement. Both the CB Warrants liability and the embedded derivative liability were 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, respectively.~~approach.

The CB Warrants liability was included in other long-term liabilities. The Company remeasured the fair value of the CB Warrants liability as of December 31, 2020 and February 24, 2021 prior to the refinancing date and recorded any adjustments as other income (expense). At both February 24, 2021 and December 31, 2020, the CB Warrants liability was $2.0 million. Due to the extinguishment of the CB Warrants on February 24, 2021, there was no 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 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 ~~March 31,~~June 30, 2021 as the CB Warrants liability was extinguished as part of the debt refinancing on February 24, 2021. For the three and ~~March 31,~~six months ended June 30, 2020, the Company recorded other income of ~~$14 thousand~~$0.1 million and ~~$0.2~~other expense of $0.1 million ~~respectively,~~ to reflect the change in ~~fair value of~~ the CB Warrants liability.

~~Table of Contents~~

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 $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 were being amortized into interest expense over the term of the 2019 Term Loans using the effective interest 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 ~~both~~the six months ended June 30, 2021. The Company did not record interest expense for the amortization of the CB Warrants liability and embedded derivative liability debt discounts for the three months ended ~~March 31,~~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 ~~2020, and recorded an additional~~embedded derivative debt discounts of $0.1 million and ~~$0.4~~$0.2 million for the three and six months ended June 30, 2020, respectively.

2019 ABL Credit Agreement - Interest Rates and Fees

2019 ABL Credit Agreement - Other Terms and Conditions

The 2019 ABL Credit Agreement was set to mature on April 12, 2022. There was also an unused line fee ranging from 0.250% to 0.375% per annum on undrawn amounts.

The 2019 ABL Credit Agreement also contained a financial maintenance covenant for the 2019 Revolving Credit Facility, which is a requirement for the Total Leverage Ratio of the Company and its ~~Subsidiaries~~subsidiaries not to exceed an amount beginning at 4.00 to 1.00 through September 30, 2019, and stepping down to 1.75 to 1.00 effective July 1, 2021. In addition, the parties to the 2019 ABL Credit Agreement entered into an amendment which, among other changes ~~revised~~revises the maximum permitted Total Leverage Ratio, starting at 3.30 to 1.00 on October 1, 2019 with a peak ratio of 4.25 during March 2020 along with varying monthly rates culminating in the lowest Total Leverage Ratio of 2.00 to 1.00 on April 1, 2021 through the term of such agreement.

As noted above in the section ~~titled “2019~~titled: 2019 Refinancing Agreement - Other Terms and Conditions,” the Company was subject to cross-default under our 2019 Revolving Credit Facility as a result of our failure to satisfy the Collateral Coverage Amount as defined in the 2019 Term Loan ~~Financing Agreement,~~financing agreement, which required the company to obtain a waiver. Accordingly, on February 1, 2021, the Company, LFS and LHLLC entered into a Waiver - Collateral Coverage Amount (December 2020) (“December 2020 Waiver”) with the lenders party thereto and Citizens Bank, N.A., as collateral agent and administrative agent. The December 2020 Waiver ~~includes~~included a waiver of the Company's compliance with the Collateral Coverage Amount for the month ending December 31, 2020. The lender has waived the event of default arising from this noncompliance as of December 31, 2020, while reserving its rights with respect to covenant compliance in future months.

Accounting for the 2019 ABL Credit Agreement

The Company incurred approximately $0.9 million of debt issuance costs for the 2019 ABL Credit Agreement that ~~have~~had been recorded as a non-current deferred asset. The deferred asset ~~is being~~was amortized into interest expense over the term of the 2019 Term ABL Credit Agreement using the effective interest method and then expensed on the February 24, 2021 refinancing date as a loss on early debt extinguishment. The Company recorded $0.1 million of interest expense ~~of $23 thousand and $0.1 million~~ for the amortization of debt issuance costs for the six months ended June 30, 2021. The Company did not record any interest expense for the amortization of debt issuance costs for the three months ended ~~March 31,~~June 30, 2021 ~~and 2020, respectively. As~~as the debt issuance costs were extinguished as part of the debt refinancing on February 24, ~~2021,~~2021.

Wintrust Term and Revolving Loans

~~Table of Contents~~

Table of Contents

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 (the “Total Leverage Ratio”)~~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 ~~March 31,~~June 30, 2021, the Company was in compliance with all ~~debt~~financial maintenance covenants as required by the Wintrust ~~Term and Revolving~~ Loans.

The following is a summary of the additional margin and commitment fees payable on the available ~~term loan~~Wintrust Term Loan and ~~revolving~~Wintrust Revolving Loan credit commitment:

Cash Flow Summary

Management continues to devote additional resources to its billing and collection efforts during the ~~three~~six months ended ~~March 31,~~June 30, 2021. Management continues to expect that growth in its ODR business, which is less sensitive to the cash flow issues presented by large GCR 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 ~~$37.2~~$27.7 million as of ~~March 31,~~June 30, 2021, cash payments to be received from existing and new customers, and availability of borrowing under the revolving line of credit under our Wintrust Loans (pursuant to which we had $21.6 million of availability as of ~~March 31,~~June 30, 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~~

Table of Contents

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 ~~March 31,~~June 30, 2021 and December 31, 2020, the Company had approximately ~~$160.7~~$265.3 million and $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 ~~March 31,~~June 30, 2021 and December 31, 2020:


(in thousands)	(in thousands)	March 31, 2021		December 31, 2020		(in thousands)	June 30, 2021		December 31, 2020

The restricted cash balance represents cash set aside for the funding of workers’ compensation and general liability insurance claims. This amount is replenished when depleted, or at the beginning of each month.

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.

~~Table of Contents~~

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 ~~March 31,~~June 30, 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 were no changes 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.

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.
