These reclassifications had no impact on net cash provided by operating activities.
The Company refined the presentation of contract-related balances within operating activities by presenting changes in contract assets and contract liabilities on a net basis, rather than as separate line items, to align with the presentation of net contract positions.

Note 2 – Summary of Significant Accounting Policies
Basis of Presentation
References in these financial statements to the Company refer collectively to the accounts of Limbach Holdings, Inc. and its wholly-owned subsidiaries, including Limbach Holdings LLC (“LHLLC”), Limbach Facility Services LLC (“LFS”), Limbach Company LLC (“LC LLC”), Limbach Company LP (“LC LP”), Harper Limbach LLC (“Harper”), Harper Limbach Construction LLC (“Harper Construction LLC”), Limbach Facility & Project Solutions LLC (“LFPS”), Jake Marshall, LLC (“JMLLC”), Coating Solutions, LLC (“CSLLC”), ACME Industrial Piping, LLC (“ACME”), Industrial Air, LLC (“Industrial Air”), Kent Island Mechanical, LLC (“Kent Island”), Consolidated Mechanical, LLC (“Consolidated Mechanical”), Pioneer Power, LLC (“Pioneer Power”), CYMCOR, LLC (“CYMCOR”) and 1901 LLC (“1901”) for all periods presented, unless otherwise indicated. All intercompany balances and transactions have been eliminated.
The accompanying unaudited condensed consolidated financial statements were prepared using generally accepted accounting principles (“GAAP”) for interim financial information and with the requirements of Form 10-Q and applicable rules of Regulation S-X of the Securities and Exchange Commission (“SEC”). Consequently, certain information and note disclosures normally included in financial statements prepared in accordance with 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 the Company’s most recent Annual Report on Form 10-K filed with the SEC on March 2, 2026.
Cash & Cash Equivalents
Cash and cash equivalents of $29.1 million and $11.3 million as of September 30, 2026 and December 31, 2025, respectively, consist of cash on hand, deposits held at financial institutions, and highly liquid investments with original maturities of three months or less.
Restricted Cash
Restricted cash of $7.0 million at September 30, 2026 is primarily comprised of cash collateral securing letters of credit outstanding under the Company's predecessor credit facility. The related restriction will be released upon the issuance of replacement letters of credit under the PNC Credit Agreement and termination of the legacy letters of credit. See Note 6 – Debt for more information. Restricted cash of $0.1 million at December 31, 2025 represents an imprest cash balance set aside for the funding of workers' compensation and general liability insurance claims. This amount is replenished either when depleted or at the beginning of each month.
Accounts Receivable and Allowance for Credit Losses
5
Accounts receivable consist primarily of amounts due from customers for services provided in the ordinary course of business. As of September 30, 2026 and December 31, 2025, trade accounts receivable were $189.0 million and $133.2 million, respectively.
The Company maintains an allowance for expected credit losses based on historical collection experience, aging of receivable balances, customer-specific risk characteristics, current economic conditions, and reasonable and supportable forecasts. The allowance for credit losses was $0.5 million and $0.4 million as of September 30, 2026 and December 31, 2025, respectively.
Use of Estimates
The preparation of the condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements for assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, the reported amounts of revenue and expenses during the reported period, and the accompanying notes. Management believes that its most significant estimates and assumptions have been based on reasonable and supportable assumptions and the resulting estimates are reasonable for use in the preparation of the condensed consolidated financial statements. The Company’s significant estimates include estimates associated with revenue recognition on construction contracts, costs incurred through each balance sheet date, intangibles, property and equipment, fair value accounting for acquisitions, insurance reserves, income tax valuation allowances, fair value of contingent consideration arrangements, and contingencies. If the underlying estimates and assumptions upon which the condensed consolidated financial statements are based change in the future, actual amounts may differ from those included in the accompanying condensed consolidated financial statements.
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, the Company has included unaudited information for these interim periods. These unaudited interim condensed consolidated financial statements have been prepared in accordance with GAAP. In the Company’s 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 September 30, 2026, its results of operations and equity for the three and nine months ended September 30, 2026 and 2025 and its cash flows for the nine months ended September 30, 2026 and 2025. The results for the three and nine months ended September 30, 2026 are not necessarily indicative of the results to be expected for the year ending December 31, 2026.
The Condensed Consolidated Balance Sheet as of December 31, 2025 was derived from the Company’s audited financial statements included in its Annual Report on Form 10-K filed with the SEC on March 2, 2026, but is presented as condensed and does not contain all the footnote disclosures from the annual financial statements.
Recent Accounting Pronouncements
In July 2025, the FASB issued Accounting Standards Update (“ASU”) 2025-05, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets. ASU 2025-05 provides a practical expedient that all entities can use when estimating expected credit losses for current accounts receivable and current contract assets arising from transactions accounted for under Accounting Standards Codification (“ASC”) Topic 606 – Revenue from Contracts with Customers. Under this practical expedient, an entity is allowed to assume that the current conditions it has applied in determining credit loss allowances for current accounts receivable and current contract assets remain unchanged for the remaining life of those assets. The Company adopted ASU 2025-05 effective January 1, 2026 on a prospective basis and elected to apply the practical expedient to its current accounts receivable and contract assets. The adoption of ASU 2025-05 did not have a material impact on the Company’s condensed consolidated financial statements or related disclosures.
In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, and in January 2025, the FASB issued ASU 2025-01, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date. ASU 2024-03 requires additional disclosure of the nature of expenses included in the income statement as well as disclosures about specific types of expenses included in the expense captions presented in the income statement. ASU 2024-03, as clarified by ASU 2025-01, is effective for fiscal years beginning after December 15, 2026, and interim periods beginning after December 15, 2027. Companies have the option to apply this guidance either on a retrospective or prospective basis, and early adoption is permitted. The Company is currently evaluating the impact that the adoption of these standards will have on its condensed consolidated financial statements and disclosures.

Note 3 – Acquisitions
1901
On September 1, 2026 (the “1901 Effective Date”), the Company, through LFS, acquired all of the outstanding equity interests of 1901 pursuant to a Purchase Agreement with the former owners of 1901 (the “1901 Purchase Agreement”). The base purchase price was $63.0 million, subject to customary closing and post-closing adjustments, including adjustments related to working capital. After giving effect to closing adjustments and cash acquired, net cash consideration paid at closing was approximately $66.0 million. Approximately $4.2 million of the purchase price was deposited into an escrow account to secure certain indemnification obligations of the former owners. In addition, the Company recorded an estimated working capital adjustment receivable of $3.3 million representing management's current estimate of the amount recoverable pursuant to the post-closing adjustment provisions of the purchase agreement. The final settlement amount remains subject to review and determination in accordance with the terms of the purchase agreement. The acquisition was funded through a combination of cash on hand and borrowings under the Company's revolving credit facility. Upon closing, 1901 became a wholly owned indirect subsidiary of the Company.
1901 is a Madison, Wisconsin-based union MEP contractor providing mechanical, electrical, plumbing, controls, design-build, construction, fabrication, service, maintenance, and underground utility solutions throughout Wisconsin and the Midwest. The acquisition expands the Company’s footprint in the Midwest, strengthens its MEPC capabilities and increases its presence across market verticals, including higher education, healthcare, and cultural facilities, while creating additional opportunities in data centers, advanced manufacturing, life sciences, and technology.
The acquisition also includes contingent consideration of up to $6.0 million, payable in cash in two tranches of $3.0 two-year period following the 1901 Effective Date, as set forth in the 1901 Purchase Agreement.
The 1901 Transaction was accounted for as a business combination using the acquisition method of accounting. As a result of the acquisition, the Company recognized preliminary goodwill of $14.3
The fair value estimates of the assets acquired and liabilities assumed, as well as the Company's estimates and assumptions, are preliminary and subject to change as additional information becomes available during the measurement period.

As of September 30, 2026, the preliminary purchase price allocation has not been finalized with respect to the valuation of identifiable intangible assets, the fair value of certain tangible assets acquired and liabilities assumed, the final working capital adjustment, goodwill and income tax-related matters. A final determination of the fair values of the assets acquired and liabilities assumed could differ from the preliminary purchase price allocation. The Company expects to finalize the valuation and complete the purchase price allocation as soon as practicable, but no later than one year from the 1901 Effective Date.
For working capital items, including cash and cash equivalents, accounts receivable, other current assets, accounts payable, accrued expenses and other current liabilities, the carrying value was assumed to approximate fair value due to the short-term nature of these instruments. There was no difference between the contractual value and fair value of the accounts receivable acquired. Contract assets and contract liabilities were recognized and measured in accordance with ASC 606, Revenue from Contracts with Customers, as if the Company had originated the related contracts.
As part of the preliminary purchase price allocation, the Company identified certain definite-lived intangible assets associated with customer relationships, acquired backlog and trade names and trademarks. The fair value of customer relationships and acquired backlog was determined using the multi-period excess earnings method under the income approach. The multi-period excess earnings method is a variation of the discounted cash flow method that isolates the cash flows attributable to a specific intangible asset and measures fair value by discounting those cash flows to present value.
The fair value of trade names and trademarks was determined using the relief-from-royalty method. This method requires identifying the future revenue expected to be generated by the asset, applying an appropriate royalty rate and discounting the resulting royalty savings to present value as of the acquisition date. The royalty rate used in the valuation was based on market rates for similar categories of assets.
The fair value of the non-compete agreements was determined using the with-or-without method under the income approach. This method measures the present value of the difference between projected cash flows assuming the non-compete agreements

are in place and those assuming the agreements are not in place, reflecting the potential impact of competition from the individuals subject to the agreements.
Significant estimates and assumptions used in determining the fair value of the identifiable intangible assets include projected revenues, profitability, customer attrition rates and discount rates, which represent Level 3 inputs.
The Company amortizes acquired finite-lived intangible assets over their estimated useful lives in a manner that reflects the expected consumption of their economic benefits. When this pattern cannot be reliably determined, the Company uses the straight-line method. The estimated amortization expense for the remainder of 2026 is approximately $2.2 million, $7.2 million for 2027, $2.3 million for 2028, and $2.1

In addition, in connection with the 1901 Transaction, the Company entered into certain retention-related bonus arrangements with key employees of 1901. These arrangements are designed to promote continued employment and support integration efforts following the acquisition. Retention-related compensation is recognized as expense ratably over the service period, which runs through August 2028, and is contingent on continued employment. Although funded from amounts withheld from the seller’s proceeds under the purchase agreement, these arrangements are accounted for separately from the acquisition as post-combination compensation expense and are excluded from consideration transferred under ASC 805, Business Combinations. Related expenses are recognized within acquisition-related retention expense and contingent consideration in the Condensed Consolidated Statements of Operations. During the three and nine months ended September 30, 2026, the Company recognized $0.1
CYMCOR
On August 4, 2026 (the "CYMCOR Effective Date"), the Company, through LFS, acquired all of the outstanding equity interests of CYMCOR pursuant to a Purchase Agreement with the former owners of CYMCOR (the "CYMCOR Purchase Agreement"). The base purchase price was $30.0 million, subject to customary closing and post-closing adjustments, including adjustments related to working capital. After giving effect to closing adjustments and cash acquired, net cash consideration paid at closing was approximately $29.9 million. Approximately $0.2 million of the purchase price was deposited into an escrow account to secure certain indemnification obligations of the former owners. In addition, the Company recorded an estimated working capital adjustment payable of less than $0.1 million representing management's current estimate of the amount payable pursuant to the post-closing adjustment provisions of the purchase agreement. The final settlement amount remains subject to review and determination in accordance with the terms of the purchase agreement. The acquisition was funded through a combination of cash on hand and borrowings under the Company's revolving credit facility. Upon closing, CYMCOR became a wholly owned indirect subsidiary of the Company.
CYMCOR is a professional services firm specializing in program management, commissioning oversight, and strategic consulting for hyperscale, colocation, enterprise, and mission-critical data center clients. CYMCOR partners directly with owners to plan, coordinate, and deliver complex projects throughout the facility lifecycle, building long-term relationships through a highly technical, service-oriented approach. The acquisition expands the Company’s professional services platform and is intended to strengthen the Company’s position within the rapidly growing data center market.
The CYMCOR Transaction was accounted for as a business combination using the acquisition method of accounting. As a result of the acquisition, the Company recognized preliminary goodwill of approximately $14.2

In connection with the CYMCOR Transaction, the Company entered into certain retention-related bonus arrangements with key employees of CYMCOR. These arrangements are designed to promote continued employment and support integration efforts following the acquisition. Retention-related compensation is recognized as expense ratably over the service period, which primarily runs through August 4, 2028, and is contingent on continued employment. The retention-related bonus arrangements are separate from, and not part of, the purchase price. Accordingly, these amounts were not included in the determination of purchase price or the allocation of purchase consideration under ASC 805, Business Combinations. Related expenses are recognized within acquisition-related retention expense and contingent consideration in the Company's Condensed Consolidated Statements of Operations. During the three and nine months ended September 30, 2026, the Company recognized $0.2
Pioneer Power
On July 1, 2025 (the "Pioneer Power Effective Date"), the Company, through LFS, acquired all the outstanding equity interests of Pioneer Power (the “Pioneer Power Transaction”) for net cash consideration of $65.7 million, after giving effect to cash acquired as part of the transaction. The acquisition was funded through a combination of cash on hand and borrowings under the Company’s revolving credit facility. Approximately $4.1 million of the cash consideration was initially held in escrow for indemnification purposes, a portion of which has subsequently been released. Pioneer Power is a provider of industrial and institutional mechanical solutions serving healthcare, food, power/utility, oil refining and other select markets in the greater Twin Cities region of Minnesota and upper Midwest regions. The acquisition further expanded the Company’s footprint into new geographic markets in the upper Midwest regions. As a result of the Pioneer Power Transaction, Pioneer Power became a wholly-owned indirect subsidiary of the Company.
The Pioneer Power Transaction was accounted for as a business combination using the acquisition method of accounting. As a result of the acquisition, the Company recognized goodwill of $39.5
During the measurement period, the Company recorded measurement period adjustments related to the Pioneer Power Transaction as additional information became available regarding the facts and circumstances that existed as of the acquisition date. The Company finalized the purchase price allocation during the three months ended June 30, 2026, and the measurement

(1) The cumulative measurement period adjustments primarily related to refinements of acquired working capital balances, including accounts payable, accrued expenses and other current liabilities, and contract assets and contract liabilities, based on additional information regarding facts and circumstances that existed as of the acquisition date. The net effect of these adjustments was recorded as a corresponding adjustment to goodwill. Certain contract liability adjustments may be subject to recovery. As of September 30, 2026, no receivable has been recognized in connection with such potential recoveries. Any future amounts recovered will not result in adjustments to the final purchase price allocation.
Note 4 – Revenue from Contracts with Customers
The Company’s revenue is primarily derived from construction-type and services contracts to deliver MEPC systems services to its customers. Such work is primarily performed under fixed-price, modified fixed-price, and time and materials contracts over periods of typically less than two years .
Construction-type contract revenue is primarily derived from fixed-price and modified fixed-price contracts. For the majority of these contracts, the Company’s performance obligations are satisfied over time because the customer controls the asset as it is created or enhanced or because the Company’s performance does not create an asset with an alternative use and the Company has an enforceable right to payment for performance completed to date. For contracts satisfied over time, the Company recognizes revenue using an input method based on costs incurred relative to total estimated costs at completion (the cost-to-cost method), which management believes depicts the transfer of control of services to the customer. The Company believes its extensive experience with MEPC systems projects, together with its internal cost estimation and review processes, enables it to reasonably estimate contract costs and mitigate the risk of cost overruns.
With respect to service contracts, the Company’s service arrangements generally include (i) fixed-price service contracts, typically for maintenance, repair and retrofit work over a period, commonly one year, and (ii) time and materials or similar service work performed on an as-needed basis. Revenue from fixed-price service contracts is generally recognized over time on a systematic basis that depicts performance over the contract term, which is typically on a straight-line basis when services are provided evenly over the contract period. Revenue derived from time and materials and other service work is recognized when the services are performed.
12
The Company generally invoices 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.
Contract Assets and Contract Liabilities
Contract assets represent the Company’s conditional right to consideration for goods or services transferred to customers when that right is conditioned on something other than the passage of time. Contract liabilities represent the Company’s obligation to transfer goods or services to customers for which consideration has been received or is due.
The Company’s contracts commonly include retainage provisions, pursuant to which a portion of billed consideration is contractually withheld by customers until achievement of specified contractual milestones, such as substantial completion, final acceptance, or satisfaction of defined performance criteria. Retainage does not represent an unconditional right to payment and is therefore not considered a trade receivable. Accordingly, retainage is reflected within contract balances based on the related net billing position.
Contract assets include costs and estimated earnings in excess of billings on uncompleted contracts and retainage associated with contracts for which the Company has a conditional right to consideration. The components of the contract asset balances as of the respective dates were as follows:

| Costs and estimated earnings in excess of billings on uncompleted contracts | $ | $ | $ | ||||||||||||||
| Retainage receivable, net | |||||||||||||||||
| Total contract assets, net | $ | $ | $ | ||||||||||||||
Contract liabilities
Contract liabilities include billings in excess of contract costs and estimated earnings on uncompleted contracts, provisions for losses and amounts related to retainage associated with overbilled contracts, which reduce billings in excess of costs until such payment become payable under contract terms. The components of the contract liability balances as of the respective dates were as follows:

| Billings in excess of costs and estimated earnings on uncompleted contracts, net | $ | $ | $ | ||||||||||||||
| Provisions for losses | |||||||||||||||||
| Total contract liabilities, net | $ | $ | $ | ||||||||||||||
Billings in excess of costs and estimated earnings on uncompleted contracts represent the excess of contract billings to date over the amount of contract costs and profits (or contract revenue) recognized to date, net of retention receivables. 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.
During the three and nine months ended September 30, 2026, the Company recognized revenue of $2.9 million and $17.1 million, respectively, that was included in its contract liabilities balance at January 1, 2026. During the three and nine months ended September 30, 2025, the Company recognized revenue of $3.4 million and $40.0 million, respectively, that was included in its contract liabilities balance at January 1, 2025.
Claims and Unapproved Change Orders
Contract assets may include amounts related to claims and unapproved change orders, which arise when there is a dispute regarding changes in scope or pricing, or when additional work is performed or costs are incurred prior to execution of a contract amendment. The Company estimates recoveries related to claims and unapproved change orders as variable
13
consideration using the most likely amount method, to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur. Such amounts generally become billable upon resolution of the underlying claim or execution of contract amendment or other written agreement. The estimated net realizable value of claims and unapproved change orders included within contract assets and contract liabilities was $16.9 million and $13.6 million as of September 30, 2026 and December 31, 2025, respectively.

Revisions in Contract Estimates
The Company recorded revisions in its contract estimates for certain ODR and GCR projects. During the three and nine months ended September 30, 2026 and 2025, the Company did no 1.0
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 include 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 September 30, 2026, the aggregate amount of the transaction prices allocated to the remaining performance obligations of the Company’s ODR and GCR segment contracts were $290.4 million and $366.1 million, respectively. The Company currently estimates that 45 % and 31 % of its ODR and GCR segment remaining performance obligations as of September 30, 2026, respectively, will be recognized as revenue during the remainder of 2026, with the substantial majority of remaining performance obligations to be recognized within 24 months, although the timing of project execution may be affected by factors outside the Company's control.
Remaining performance obligations differ from backlog because certain ODR contracts are excluded from remaining performance obligations as they may be canceled for convenience by either party without significant penalty.
Note 5 – Goodwill and Intangibles
Goodwill
Goodwill was $101.2 million and $70.6 million as of September 30, 2026 and December 31, 2025, respectively. The Company evaluates its goodwill and indefinite-lived intangible assets allocated to its reporting units for impairment annually on October 1, or more frequently if events or circumstances indicate that it is more likely than not that the fair value of its reporting units and indefinite-lived intangible assets are less than their carrying amount.
The Company did not

PNC Credit Facility
On September 9, 2026 (the “PNC Closing Date”), LFS, LHLLC, and other designated parties entered into a credit agreement with PNC Bank, National Association (“PNC”), as administrative agent, and other lenders party thereto (the “PNC Credit Agreement”), which provides for aggregate commitments of up to $300.0 million (the “PNC Credit Facility”), consisting of:
(i) a revolving credit facility with an aggregate principal amount of $200.0 million (the “PNC Revolving Credit Facility”), including a $20.0 million swingline loan subfacility and a $25.0 million letter of credit subfacility;
(ii) a term loan facility with an aggregate principal amount of $50.0 million (the “PNC Term Loan Facility”); and
(iii) a delayed draw term loan facility with aggregate commitments of $50.0 million (the “PNC DDTL Facility”).
The revolving credit facility and term loan facility mature on September 9, 2031. Subject to the provisions of the PNC Credit Agreement, commitments under the delayed draw term loan facility remain available through March 9, 2028. Subject to specified conditions and lender commitments, the PNC Credit Agreement also permits incremental credit facilities and commitment increases of up to the greater of $150.0 million and 100 % of Consolidated EBITDA.
The obligations under the PNC Credit Agreement are guaranteed by the Company, LHLLC and certain subsidiaries and are secured by substantially all assets of LFS and the guarantors, subject to customary exceptions.
Subject to the provisions of the PNC Credit Agreement, borrowings under the PNC Credit Facility bear interest, at LFS's option, at either
(i) a base rate plus an applicable margin ranging from 0.50 % to 1.50 %; or
(ii) Term SOFR plus an applicable margin ranging from 1.50 % to 2.50 %,
with applicable margins determined by reference to LFS's Consolidated Net Leverage Ratio. The PNC Credit Agreement includes commitment fees on the unused portions of the PNC Revolving Credit Facility and the PNC DDTL Facility at a rate ranging from 0.20 0.35
The PNC Term Loan Facility is repayable in quarterly principal installments beginning December 31, 2026, with the remaining outstanding principal due at maturity.
The PNC Credit Agreement contains customary affirmative and negative covenants, representations and warranties and events of default, including financial covenants requiring LFS to maintain (i) a maximum Consolidated Net Leverage Ratio of 3.00 to 1.00 and (ii) a minimum Consolidated Fixed Charge Coverage Ratio of 1.15 to 1.00. The maximum Consolidated Net Leverage Ratio may be increased to 3.50 to 1.00 for four consecutive fiscal quarters following certain qualifying acquisitions.

The Company incurred approximately $1.8 million in debt issuance costs in connection with the PNC Credit Agreement. Debt issuance costs attributable to the funded PNC Term Loan Facility are presented as a direct deduction from the related debt balance. Debt issuance costs attributable to the PNC Revolving Credit Facility are included in other noncurrent assets and amortized over the term of the facility. Debt issuance costs attributable to the undrawn PNC DDTL Facility are included in other noncurrent assets and will be reclassified as a reduction of the carrying amount of the related debt to the extent borrowings are made. As of September 30, 2026, approximately $0.3 million of unamortized debt issuance costs attributable to the undrawn PNC DDTL Facility were included in other noncurrent assets.
In connection with entering into the PNC Credit Agreement, on the PNC Closing Date, the Company terminated its prior Wintrust credit facility and repaid approximately $118.1 million of outstanding borrowings using proceeds from the PNC Credit Facility. The Company recorded a loss on extinguishment of debt of approximately $0.2 million related to the write-off of unamortized debt issuance costs associated with the terminated facility.
As of September 30, 2026, the Company had $75.0 million in borrowings outstanding under the PNC Revolving Credit Facility and $50.0 million outstanding under the PNC Term Loan Facility, with a weighted average annual interest rate of 5.50 % and 5.50 %, respectively. Remaining availability under the PNC Revolving Credit Facility was $125.0 million, after giving effect to outstanding borrowings. No amounts were outstanding under the PNC DDTL Facility, and the full $50.0 million commitment remained available. Of the combined $175.0 million in unused commitments, approximately $39.9 million was unavailable due to financial covenant limitations, resulting in approximately $135.1 million of available borrowing capacity as of September 30, 2026. Availability under these facilities is subject to satisfaction of the applicable borrowing conditions, including compliance with financial covenants and the absence of specified defaults.
In connection with the closing of the PNC Credit Agreement and termination of the Wheaton Bank & Trust Company, N.A., a subsidiary of Wintrust Financial Corporation (collectively, “Wintrust”) credit facility, letters of credit totaling approximately $7.0 million remained outstanding as of September 30, 2026. These letters of credit expire no later than April 2027 and will be replaced with letters of credit issued under the PNC Credit Agreement. The Company maintains cash collateral of approximately $7.0 million, which is included in restricted cash on the Company's condensed consolidated balance sheets and will be released upon termination and replacement of the related legacy letters of credit. No amounts had been drawn under these letters of credit as of September 30, 2026.
As of September 30, 2026, the Company was in compliance with all financial maintenance covenants under the PNC Credit Agreement.
As of September 30, 2026, future maturities of debt outstanding under the PNC Credit Facility are as follows (in thousands):

Former Wintrust Revolving Credit Facility
Prior to entering into the PNC Credit Agreement, the Company maintained a senior secured revolving credit facility with Wintrust, as administrative agent, pursuant to a Second Amended and Restated Credit Agreement originally entered into on May 5, 2023 (the “Second A&R Wintrust Credit Agreement”).
On July 24, 2026, LFS, LHLLC, and certain other designated parties entered into the Third Amendment to the Second A&R Wintrust Credit Agreement with Wintrust, as administrative agent, which increased total commitments from $100.0 million to $125.0 million and modified certain pricing and other terms. The Wintrust revolving credit facility was terminated on September 9, 2026 in connection with the Company's entry into the PNC Credit Agreement.
For the period from July 1, 2026 through September 9, 2026, maximum borrowings outstanding under the Wintrust revolving credit facility were $118.1 million and average daily borrowings were $28.0 million. For the period from January 1, 2026 through September 9, 2026, maximum borrowings outstanding were $118.1 million and average daily borrowings were $20.1 million. During the three and nine months ended September 30, 2025, maximum borrowings outstanding were $50.0 million and average daily borrowings were $48.0 million and $22.8 million, respectively.
17
For the period from July 1, 2026 through September 9, 2026 and for the period from January 1, 2026 through September 9, 2026, borrowings under the Wintrust revolving credit facility bore weighted average annual interest rates of 5.77 % and 5.64 %, respectively, inclusive of the net impact of the Company's interest rate swap arrangement. For the three and nine months ended September 30, 2025, borrowings under the Wintrust revolving credit facility bore weighted average annual interest rates of 6.28 % and 6.12 %, respectively.
Interest Rate Swap
Prior to the termination of the Wintrust revolving credit facility, the Company maintained an interest rate swap agreement to manage its exposure to interest rate variability associated with a portion of its variable-rate debt. The swap agreement became effective on July 14, 2022 and was scheduled to mature on July 31, 2027. The swap had a notional amount of $10.0 million and effectively fixed the underlying benchmark interest rate at 3.12 %, subject to the applicable credit spread under the related debt agreement. The Company did not designate the swap as a hedge for accounting purposes; accordingly, changes in the fair value of the derivative were recognized in earnings within gain (loss) on interest rate swap.
In connection with the termination of the Wintrust revolving credit facility and entry into the PNC Credit Agreement, the Company terminated the swap and received settlement proceeds of approximately $0.1 million. The Company remeasured the derivative to fair value immediately prior to settlement, recognized the resulting adjustment in earnings and derecognized the instrument upon settlement. No amounts remained outstanding under the swap as of September 30, 2026.
Sale-Leaseback Financing Transaction
On September 29, 2022, the Company completed a sale and leaseback transaction related to its facility in Pontiac, Michigan (the “Pontiac Facility”), with an aggregate transaction value of approximately $7.8 million, consisting of a purchase price of approximately $5.4 million and up to $2.4 million of tenant improvement allowances.
In connection with the transaction, the Company entered into a 25 -year lease agreement with two five-year renewal options. Annual minimum rent is approximately $0.5 million, payable monthly and subject to annual escalations of approximately 2.5 %. The lease includes a one-time termination option at the end of the fifteenth lease year, which would require payment of a termination fee of approximately $1.7 million if exercised.
The Company accounted for the transaction as a failed sale-leaseback and financing arrangement under ASC Topic 842 – Leases, as the lease was classified as a finance lease and control of the property did not transfer to the buyer-lessor. Accordingly, no gain or loss was recognized, and the property was not derecognized from the Company’s condensed consolidated balance sheets and continues to be recognized therein. Proceeds received were recorded as a financing liability and are repaid through lease payments, which are allocated between principal and interest.
Note 7 – Equity
The Company’s second amended and restated certificate of incorporation currently authorizes the issuance of 100,000,000 shares of common stock, par value $0.0001 , and 1,000,000 shares of preferred stock, par value $0.0001 .
Incentive Plan
Upon the consummation of the Company’s business combination with LHLLC in July 2016, the Company adopted an omnibus incentive plan (as amended, the “Omnibus Incentive Plan”) pursuant to which equity awards may be granted thereunder. See Note 14 – Management Incentive Plans for a discussion of the Company’s management incentive plans for restricted stock units (“RSUs”) granted, vested, forfeited and remaining unvested.
Share Repurchase Program
In December 2025, the Company announced that its Board of Directors authorized a share repurchase program (the “Share Repurchase Program”), pursuant to which the Company may, from time to time, purchase up to $50.0 million of shares of its common stock through December 15, 2027. Share repurchases may be executed through various means, including, without limitation, open market transactions, privately negotiated transactions or by other means in accordance with federal securities laws. Repurchases may also be made under Rule 10b5-1 plans. The Share Repurchase Program does not obligate the Company to acquire any particular amount of common stock, and the program may be suspended or terminated by the Company at any time at its discretion without prior notice. As of September 30, 2026, the Company had repurchased 194,788 shares under the
18
Share Repurchase Program at an average price of $51.31 per share for an aggregate cost of approximately $10.0 million. The repurchased shares are held as treasury stock.
Employee Stock Purchase Plan
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”), which became effective on January 1, 2020. The ESPP permits eligible employees to purchase shares of the Company's common stock through payroll deductions at a purchase price equal to 85 % of the fair market value of the Company's common stock at the end of each offering period. Offering periods are six months in duration and commence on January 1st and July 1st of each year. A total of 500,000 shares of common stock are authorized for issuance under the ESPP.
In January 2026 and July 2026, the Company issued 3,305 and 3,926 shares of common stock, respectively, under the ESPP. In January 2025 and July 2025, the Company issued a total of 2,321 and 2,175 shares of common stock, respectively, under the ESPP. As of September 30, 2026, 371,139 shares of common stock remain available for future issuance under the ESPP.
Note 8 – Fair Value Measurements
The Company measures the fair value of financial assets and liabilities in accordance with ASC Topic 820 – Fair Value Measurements and Disclosures, which defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. ASC Topic 820 establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value and requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to measurements involving significant unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are as follows:
•Level 1 — inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that are accessible at the measurement date;
•Level 2 — inputs other than quoted prices included in Level 1 that are observable for the asset or liability either directly or indirectly such as quoted prices in active markets for similar assets and liabilities, quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of assets or liabilities; and
•Level 3 — unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions.
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. The Company considers all highly liquid investments purchased with a maturity of 90 days or less on the date of purchase to be cash equivalents. Cash equivalents as of September 30, 2026 and December 31, 2025 consisted of overnight repurchase agreements in which cash from the Company’s main operating checking account is invested overnight in highly liquid, short-term investments and certain investments in money market funds sponsored by a large financial institution. For both the three and nine months ending September 30, 2026, interest income in the aggregate was approximately $0.1 0.1 million and $0.8 million, respectively. The Company has not experienced any losses in its cash and cash equivalents and management believes the Company is not exposed to significant credit risk with respect to such accounts.

PNC Credit Facility
As of September 30, 2026, the estimated fair values of borrowings outstanding under the PNC Revolving Credit Facility and PNC Term Loan Facility were approximately $75.0 million and $50.0 million, respectively, and approximated their carrying amounts before the deduction of unamortized debt issuance costs. The fair values were estimated using discounted cash flow analyses based on current market interest rates for similar debt instruments and were classified as Level 2 within the fair value hierarchy.
Earnout Payments
As a part of the total consideration for the Company’s November 2023 acquisition of Industrial Air, the former owner of Industrial Air was eligible to receive up to an aggregate of $6.5 million in cash, consisting of two individual tranches of $3.0 million and $3.5 million pursuant to the terms of the purchase agreement, if the gross profit of Industrial Air equaled or exceeded (i) $7.6 million in the 12 -month period beginning on the closing date of the transaction (the “First IA Earnout Period”) or (ii) $8.8 million in the 12 -month period beginning on the first anniversary of the closing date of the transaction (the “Second IA Earnout Period” and together with the First IA Earnout Period, the “IA Earnout Payments”). The Company initially recognized $3.2 million in contingent consideration as of the closing date of the transaction. The fair value of contingent IA Earnout Payments was based on generating growth rates on the projected gross margins of Industrial Air and calculating the associated contingent payments based on achieving the earnout targets, which were reassessed each reporting period. In February 2026 and February 2025, the Company made payments in the amount of $3.5 million and $3.0 million, respectively, to the former owner of Industrial Air related to the First and Second Industrial Air Earnout Periods.
As a part of the total consideration for the Company’s September 2024 acquisition of Kent Island, the former owner of Kent Island is eligible to receive up to an aggregate of $5.0 million in cash, consisting of two individual tranches of $2.5 million pursuant to the terms of the purchase agreement, if the gross profit of Kent Island equals or exceeds approximately (i) $3.3 million in the 12 -month period beginning on the closing date of the transaction (the “First Kent Island Earnout Period”) or (ii) $0.2 million in the 12 -month period beginning on the first anniversary of the closing date of the transaction (the “Second Kent Island Earnout Period” and together with the First Kent Island Earnout Period, the “Kent Island Earnout Payments”). The Company initially recognized $4.4 million in contingent consideration as of the closing date of the transaction. The fair value of contingent Kent Island Earnout Payments are based on generating growth rates on the projected gross margins of Kent Island and calculating the associated contingent payments based on achieving the earnout targets, which are reassessed each reporting period. In January 2026, the Company made a payment in the amount of $2.5 million to the former owner of Kent Island related to the First Kent Island Earnout Period.
As a part of the total consideration for the Company’s December 2024 acquisition of Consolidated Mechanical, the former owner of Consolidated Mechanical is eligible to receive up to an aggregate of $2.0 million in cash, consisting of two individual tranches of $1.0 million pursuant to the terms of the purchase agreement, if the gross profit of Consolidated Mechanical equals or exceeds approximately (i) $6.8 million in the 12 -month period beginning on the closing date of the transaction (the “First Consolidated Mechanical Earnout Period”) or (ii) $6.8 million in the 12 -month period beginning on the first anniversary of the closing date of the transaction (the “Second Consolidated Mechanical Earnout Period” and together with the First Consolidated Mechanical Earnout Period, the “Consolidated Mechanical Earnout Payments”). The Company initially recognized $0.8 million in contingent consideration as of the closing date of the transaction. The fair value of contingent Consolidated Mechanical Earnout Payments is based on generating growth rates on the projected gross margins of Consolidated Mechanical and calculating the associated contingent payments based on achieving the earnout targets, which are reassessed each reporting period. In April 2026, the Company made a payment in the amount of $0.9 million to the former owner of Consolidated Mechanical related to the First Consolidated Mechanical Earnout Period.
As a part of the total consideration for the Company’s September 2026 acquisition of 1901, the 1901 Sellers are eligible to receive up to an aggregate of $6.0 million in cash, consisting of two individual tranches of $3.0 4.8 million in contingent consideration as of the 1901 Effective Date. The fair value of contingent 1901 Earnout Payments is based on generating growth rates on the projected gross margins of 1901 and calculating the associated contingent payments based on achieving the earnout targets, which are reassessed each reporting period.
Based on the Company’s ongoing assessment of the fair value of contingent earnout liabilities, the Company recorded a net increase in the estimated fair value of such liabilities of $0.2 million and $0.3 million for the three and nine months ended September 30, 2026, respectively, which was presented in the acquisition-related retention expense and contingent consideration in the Company’s condensed consolidated statements of operations. For the three and nine months ended September 30, 2025, the Company recorded a net increase in the estimated fair value of such liabilities of $0.3 million and
20
$1.5 million, respectively. The Company determined the fair value of the earnout payments by utilizing the Monte Carlo Simulation method, which represents a Level 3 measurement.
The following table presents the carrying values of the Company’s contingent earnout payment obligations included in the accompanying condensed consolidated balance sheets, which approximated fair value at September 30, 2026 and December 31, 2025.

(3) In April 2026, the Company made a $0.9 million payment to the former owner of Consolidated Mechanical related to the First Consolidated Mechanical Earnout Period.
Interest Rate Swap
Prior to its termination, the fair value of the interest rate swap was determined using observable market inputs, including interest rate curves, and incorporated assumptions regarding the nonperformance risk of both the Company and the counterparty. Accordingly, the interest rate swap was classified as a Level 2 item within the fair value hierarchy.
In connection with the termination of the Wintrust revolving credit agreement, the Company terminated and settled the interest rate swap on September 9, 2026. The swap was remeasured to fair value immediately prior to settlement, with the resulting adjustment recognized in earnings, and was derecognized upon settlement. Accordingly, no interest rate swap asset remained outstanding as of September 30, 2026. As of December 31, 2025, the swap had a fair value of less than $0.1 million and was recognized in other assets on the Company’s condensed consolidated balance sheets.
For the three and nine months ended September 30, 2026, the Company recognized a loss of less than $0.1 million and a gain of approximately $0.1 million, respectively, related to the changes in the fair value of the interest rate swap. For the three and nine months ended September 30, 2025, the Company recognized losses of less than $0.1 million and $0.2 million, respectively, related to the changes in the fair value of the interest rate swap.

Note 9 – Earnings per Share
Earnings per Share
The Company calculates earnings per share in accordance with ASC Topic 260 – Earnings Per Share (“EPS”). Basic earnings per share of the Company’s common stock applicable to common stockholders is computed by dividing earnings applicable to common stockholders by the weighted-average number of shares of the Company’s common stock outstanding and assumed to be outstanding. Diluted EPS assumes the dilutive effect of outstanding common stock warrants and shares issued in conjunction with the Company’s ESPP and RSUs, all using the treasury stock method.
The following table sets forth the computation of the basic and diluted earnings per share attributable to the Company’s common stockholders for the three and nine months ended September 30, 2026 and 2025:

Note 10 – Income Taxes
The Company is taxed as a C corporation and files income tax returns in the U.S. federal jurisdiction and in various state jurisdictions.
For interim periods, the provision for income taxes (including federal, state and local taxes) is calculated based on the estimated annual effective tax rate, adjusted for certain discrete items for the full fiscal year. Cumulative adjustments to the Company’s estimate are recorded in the interim period in which a change in the estimated annual effective rate is determined. Each quarter the Company updates its estimate of the annual effective tax rate, and if its estimated tax rate changes, the Company makes a cumulative adjustment.
The following table presents the Company’s income tax expense and its income tax rate for the three and nine months ended September 30, 2026 and 2025.

| Income tax expense | $ | $ | $ | $ | ||||||||||||||||||||||
| Income tax rate | % | % | % | % | ||||||||||||||||||||||
The U.S. federal statutory tax rate was 21% for each of the three and nine months ended September 30, 2026 and 2025. The Company’s effective tax rate differed from the U.S. federal statutory tax rate primarily due to state income taxes, federal tax credits, other permanent adjustments and discrete tax items.
The Company’s effective tax rates for the nine months ended September 30, 2026 and 2025 were significantly impacted by excess tax benefits related to the vesting of restricted stock units (“RSUs”) (see Note 14) which were recorded as discrete tax benefits during the first quarter of each year. The amount of these excess tax benefits is primarily dependent on the Company’s stock price on the applicable vesting dates. The excess tax benefits reduced the first-quarter effective tax rate by approximately 533.3 % and 53.5 % during 2026 and 2025, respectively.
Note 11 – Operating Segments
As discussed in Note 1, the Company operates in two segments (i) ODR, in which the Company performs owner direct projects and/or provides maintenance or service primarily on MEPC systems, and specialty contracting projects to existing buildings direct to, or assigned by, building owners or operators, and (ii) GCR, in which the Company generally manages new construction or renovation projects that involve primarily MEPC systems awarded to the Company by general contractors or construction managers.
Segment information is prepared on the same basis 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 President and Chief Executive Officer and Executive Vice President and Chief Financial Officer. The Company’s CODM evaluates segment performance and makes resource allocation decisions primarily based on gross profit. Gross profit is a key measure used by the CODM in the annual budgeting and forecasting process, as well as in periodic reviews of actual operating results compared to planned performance. The CODM uses the Company's gross profit measure to assess the operating performance of its reportable segments, establish business priorities, and make decisions regarding the allocation of capital and other resources among those segments.
All of the Company’s identifiable assets are located in the United States, which is where the Company is domiciled.

Note 13 – Commitments and Contingencies
Legal. The Company is continually involved in administrative proceedings, arbitrations, and litigation with owners, general contractors, suppliers, employees, former employees and other unrelated parties, all arising in the ordinary courses of business.

The ultimate resolution of these contingencies could, individually or in the aggregate, be material to the condensed consolidated financial statements. Management currently believes 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.
Surety. The terms of its construction contracts frequently require that the Company obtain from surety companies, and provide to its customers, payment and performance bonds (“Surety Bonds”) as a condition to the award of such contracts. The Surety Bonds secure the Company’s payment and performance obligations under such contracts, and the Company has agreed to indemnify the surety companies for amounts, if any, paid by them in respect of Surety Bonds issued on its behalf. In addition, at the request of labor unions representing certain of the Company’s 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, the Company’s bonding requirements typically increase as the amount of public sector work increases. As of September 30, 2026, the Company had approximately $121.6 million in surety bonds outstanding. The Surety Bonds are issued by surety companies in return for premiums, which vary depending on the size and type of bond.
Collective Bargaining Agreements. Many of the Company’s craft labor employees are covered by collective bargaining agreements. The agreements require the Company to pay specified wages, provide certain benefits and contribute certain amounts to multi-employer pension plans. If the Company withdraws from any of the multi-employer pension plans or if the plans were to otherwise become underfunded, the Company could incur additional liabilities related to these plans. Although the Company has been informed that some of the multi-employer pension plans to which it contributes have been classified as “critical” status, the Company is not currently aware of any significant liabilities related to this issue.
Self-insurance. The Company is substantially self-insured for workers’ compensation and general liability claims, due to the relatively high per-occurrence deductibles under its insurance programs. The Company purchases workers’ compensation and general liability insurance under policies with per-incident deductibles of $250,000 per occurrence and a $7.9 million maximum aggregate deductible loss limit per year. Losses incurred over primary policy limits are covered by umbrella and excess policies up to specified limits with multiple excess insurers. The Company accrues 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 determined by establishing 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.
The Company is also self-insured for medical and dental claims under policies with annual per-claimant and annual aggregate stop-loss limits. The Company accrues 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 as of September 30, 2026 and December 31, 2025 are as follows:

The restricted cash balance represents an imprest cash balance set aside for the funding of workers' compensation and general liability insurance claims. This amount is replenished either when depleted or at the beginning of each month.
Note 14 – Management Incentive Plans
The Company maintains the Omnibus Incentive Plan to provide equity-based and cash-based incentive awards to employees, directors and consultants. The Omnibus Incentive Plan provides for grants of options, stock appreciation rights, restricted shares, RSUs, performance-based awards (including performance-based restricted shares and restricted stock units), other share-based awards, other cash-based awards or any combination thereof.
27
Service-Based Awards
The Company grants service-based stock awards in the form of RSUs. Service-based RSUs granted to executives, employees, and non-employee directors vest ratably, on an annual basis, over three years and in the case of certain awards to non-employee directors, over one year . The grant date fair value of the service-based awards was equal to the closing market price of the Company’s common stock on the date of grant. For both the three months ended September 30, 2026 and 2025, the Company recognized $0.6 2.0 million and $1.7 million, respectively, of stock-based compensation expense related to outstanding service-based RSUs.
The following table summarizes the Company’s service-based RSU activity for the nine months ended September 30, 2026:

Performance-Based Awards
The Company has granted performance-based restricted stock units (“PRSUs”) under which shares of the Company’s common stock may be earned based on the Company’s performance compared to defined metrics. The number of shares earned under a performance award may vary from zero to 150 % of the target shares awarded, based upon the Company’s performance compared to the metrics. The metrics used for the grant are determined by the Company’s Compensation Committee of the Board of Directors and are based on internal measures such as the achievement of certain predetermined adjusted EBITDA and EBITDA margin performance goals generally over a three-year period.
The Company recognizes non-cash stock-based compensation expense for these awards over the vesting period based on the projected probability of achievement of the 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 months ended September 30, 2026 and 2025, the Company recognized $0.3 million and $1.0 million, respectively, of non-cash stock-based compensation expense related to outstanding PRSUs. For the nine months ended September 30, 2026 and 2025, the Company recognized $1.4 million and $2.4 million, respectively, of stock-based compensation expense related to outstanding PRSUs. All unvested PRSU awards as of September 30, 2026 are related to awards granted in fiscal year 2024.
The following table summarizes the Company’s PRSU activity for the nine months ended September 30, 2026:

(1) Performance-based awards covering the three-year period ended December 31, 2025 were paid out in the first quarter of 2026 based on the approval of the Company’s Compensation Committee. The performance factor during the measurement period used to determine compensation payouts was 150 % of the pre-defined metric target of 100 %, which resulted in a positive performance factor adjustment and the issuance of 99,690 shares of the Company’s common stock as additional awards associated with the original grant.
28
Market-Based Awards
The Company grants market-based RSUs (“MRSUs”) to certain employees that vest based on the Company’s total shareholder return (“TSR”) relative to the TSR of the Russell 2000 Index over a three-year performance period. The number of shares that ultimately vest can range from 0 % to 150 % of the target award, based on the Company’s TSR percentile ranking relative to the Russell 2000 Index constituents during the performance period.
Because vesting is subject to a market condition, the grant date fair value of these awards was estimated using a Monte Carlo simulation model. The assumptions used in the model included expected volatility for the Company and the Russell 2000 Index, risk-free interest rates, expected dividend yields, and the correlation between the Company’s stock and the Russell 2000 Index. The grant date fair value is expensed over the requisite three-year performance period using a straight-line method, as long as the employee remains employed during the performance period. For the three months ended September 30, 2026, and 2025 the Company recognized $0.6 million and $0.4 million, respectively, of non-cash stock-based compensation expense related to outstanding MRSUs. For the nine months ended September 30, 2026, and 2025 the Company recognized $2.1 million and $1.1 million, respectively, of non-cash stock-based compensation expense related to outstanding MRSUs.

Stock-Based Compensation Expense
Total recognized non-cash stock-based compensation expense amounted to $1.5 million and $1.9 million for the three months ended September 30, 2026 and 2025, respectively. For the nine months ended September 30, 2026 and 2025, the Company recognized non-cash stock-based compensation expense of $5.5 million and $5.2 million, respectively. The aggregate fair value as of the vest date of RSUs that vested during the nine months ended September 30, 2026 and 2025 was $31.2 million and $29.7 million, respectively. Total non-cash unrecognized stock-based compensation expense related to unvested RSUs that are probable of vesting was $7.9 million at September 30, 2026. These costs are expected to be recognized over a weighted average period of 1.74 years.

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. See “Cautionary Note Regarding Forward-Looking Statements” contained above in this Quarterly Report on Form 10-Q. The Company assumes no obligation to update any of these forward-looking statements, unless required to do so by applicable law.
Unless the context otherwise requires, a reference to a “Note” herein refers to the accompanying Notes to Condensed Consolidated Financial Statements (Unaudited) contained in Part I, "Item 1. Financial Statements."
Overview
The Company is a building systems solutions firm that designs, delivers, and maintains mechanical (heating, ventilation, and air conditioning), electrical, plumbing, and controls (“MEPC”) systems. The Company partners with building owners and operators of mission-critical facilities across healthcare, industrial and manufacturing, data centers, life sciences, higher education, and cultural and entertainment markets. As of September 30, 2026, the Company had approximately 2,100 team members across 23 offices throughout the Eastern and Midwestern regions of the United States. The Company strives to be an indispensable partner by combining its national capabilities with strong local execution and talent to deliver proactive, safe, and reliable solutions for complex facilities. Operating on a connected platform, the Company integrates engineering expertise with field execution to provide customized MEPC infrastructure solutions that address both operational and capital project needs, optimizing performance, enhancing reliability, and ensuring long-term safety.
The Company’s core market sectors consist of the following customer base with mission-critical systems:
•Healthcare, including research, acute care and inpatient hospitals for regional and national hospital groups;
•Industrial and manufacturing, including automotive, energy and general manufacturing plants;
•Data centers, including facilities composed of networked computers, storage systems and computing infrastructure that organizations use to assemble, process, store and disseminate large amounts of data;
•Life sciences, including organizations and companies whose work is centered around research and development focused on living organisms and biological systems;
•Higher education, including both public and private colleges, universities and research centers; and
•Cultural and entertainment, including entertainment facilities (including casinos) and amusement rides and parks.
The Company operates in two segments, (i) ODR, in which the Company performs owner direct projects and/or provides maintenance or service primarily on MEPC systems, and specialty contracting projects to existing buildings direct to, or assigned by, building owners or operators, and (ii) GCR, in which the Company generally manages new construction or renovation projects that involve primarily MEPC systems awarded to the Company by general contractors or construction managers. The Company’s work is primarily performed under fixed-price, modified fixed-price, and time and materials contracts over periods of typically less than two years.
Key Components of Condensed Consolidated Statements of Operations
Revenue
The Company’s revenue is primarily derived from construction-type and services contracts to deliver MEPC systems services to its customers. Such work is primarily performed under fixed-price, modified fixed-price, and time and materials contracts over periods of typically less than two years.
Construction-type contract revenue is primarily derived from fixed-price and modified fixed-price contracts. For the majority of these contracts, the Company’s performance obligations are satisfied over time because the customer controls the asset as it is created or enhanced or because the Company’s performance does not create an asset with an alternative use and the Company has an enforceable right to payment for performance completed to date. For contracts satisfied over time, the Company recognizes revenue using an input method based on costs incurred relative to total estimated costs at completion (the cost-to-cost method), which management believes depicts the transfer of control of services to the customer. The Company believes its extensive experience with MEPC systems projects, together with its internal cost estimation and review processes, enables it to reasonably estimate contract costs and mitigate the risk of cost overruns.
30
With respect to service contracts, the Company’s service arrangements generally include (i) fixed-price service contracts, typically for maintenance, repair and retrofit work over a period, commonly one year, and (ii) time and materials or similar service work performed on an as-needed basis. Revenue from fixed-price service contracts is generally recognized over time on a systematic basis that depicts performance over the contract term, which is typically on a straight-line basis when services are provided evenly over the contract period. Revenue derived from time and materials and other service work is recognized when the services are performed.
The Company generally invoices 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 labor, equipment, material, subcontract and other job costs in connection with fulfilling the terms of the Company’s 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 the Company’s services, and the risks associated therewith, contract costs as a percentage of contract revenue have historically fluctuated, and this fluctuation is expected to continue in future periods as well.
Selling, General and Administrative
Selling, general and administrative (“SG&A”) expenses consist primarily of personnel costs for the Company’s administrative, estimating, human resources, safety, information technology, legal, finance and accounting team members and executives. Also included in SG&A expenses are non-personnel costs, such as travel-related expenses, legal and other professional fees and other corporate expenses to support the growth of the Company’s business and to meet the compliance requirements associated with operating as a public company. Those costs include 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 of 2002.
Acquisition-related Retention Expense and Contingent Consideration
As part of the acquisitions of Pioneer Power, CYMCOR and 1901, the Company implemented retention arrangements for certain key employees of the acquired businesses. Retention-related compensation is contingent on continued employment and is recognized as expense ratably over the respective required service periods.
Certain of the Company’s prior acquisitions include contingent earnout arrangements in which the Company may be required to make additional payments contingent upon the acquired businesses achieving specified performance targets over specified periods. The change in fair value of contingent consideration relates to the remeasurement of the contingent consideration arrangements resulting from the acquisitions of each of ACME, Industrial Air, Kent Island, Consolidated Mechanical and 1901. The carrying values of the ACME, Industrial Air, Kent Island, Consolidated Mechanical and 1901 earnout payments are subject to remeasurement at fair value at each reporting date through the end of the respective earnout periods with any changes in the fair value reported as a separate component of operating income in the condensed consolidated statements of operations. See Note 8 – Fair Value Measurements in the accompanying notes to the Company’s condensed consolidated financial statements for further information on the Company’s contingent earnout arrangements.
Amortization of Intangibles
Amortization expense represents periodic non-cash charges that consist of amortization of various intangible assets primarily including customer relationships, backlog, trade name, trademarks and intellectual property, favorable leasehold interests, developed technology and non-compete agreements. Each of the Company's acquisition-related intangible assets was recorded under the acquisition method of accounting at their estimated fair values at the acquisition date. See Note 5 – Goodwill and Intangible Assets in the accompanying notes to the Company’s condensed consolidated financial statements for further information on the Company’s intangible assets.
Other (Expenses) Income
Other (expenses) income consists primarily of interest expense incurred in connection with the Company’s indebtedness, gains and losses on dispositions of property and equipment, changes in the fair value of the Company’s interest rate swap, a loss on early debt extinguishment and interest income earned on overnight repurchase agreements. Deferred financing costs are amortized to interest expense using the effective interest method.
31
Provision for Income Taxes
The Company is taxed as a C corporation, and its financial results include the effects of federal income taxes, which are paid at the parent level.
The Company’s provision for income taxes (including federal, state and local income taxes) is calculated based on the estimated annual effective tax rate. The Company accounts for income taxes in accordance with Accounting Standards Update (“ASC”) Topic 740 – Income Taxes, which requires an asset and liability approach. Under this approach, 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 amounts of existing assets and liabilities and their respective tax bases, using enacted tax rates expected to apply in the periods in which those temporary differences are expected to reverse. Changes in deferred tax assets and liabilities are included in the provision for income taxes.
Impact of Acquisitions
In order to provide a more meaningful discussion of period-over-period changes in the Company’s operating results, the Company may discuss the impact of acquisitions on revenue, gross profit, selling, general and administrative expenses, and operating income. Because acquired businesses are included in the Company’s results only from their respective acquisition dates, the size and timing of acquisitions may affect the comparability of period-over-period results. Accordingly, such comparisons may not be fully indicative of ongoing trends in the Company’s operating performance.
On September 1, 2026, the Company completed the acquisition of Madison, Wisconsin-based mechanical contractor, 1901. 1901 is a union MEP contractor providing mechanical, electrical, plumbing, controls, design-build, construction, fabrication, service, maintenance, and underground utility solutions throughout Wisconsin and the Midwest. The acquisition further expands the Company’s footprint in the core Midwest, strengthens its MEPC capabilities and increases its exposure across market verticals, including higher education, healthcare, and cultural facilities, while creating additional opportunities in data centers, advanced manufacturing, life sciences, and technology.
On August 4, 2026, the Company completed the acquisition of Frisco, Texas-based professional services firm, CYMCOR. CYMCOR is a professional services firm specializing in program management, commissioning oversight, and strategic consulting for hyperscale, colocation, enterprise, and mission-critical data center clients. CYMCOR partners directly with owners to plan, coordinate, and deliver complex projects throughout the facility lifecycle, building long-term relationships through a highly technical, service-oriented approach. The acquisition expands the Company’s professional services platform and strengthens the Company’s position within the rapidly growing data center market.
On July 1, 2025, the Company completed an acquisition of Woodbury, Minnesota-based mechanical contractor, Pioneer Power. Pioneer Power is a provider of industrial and institutional mechanical solutions serving healthcare, food, power/utility, oil refining and other select markets in the greater Twin Cities region of Minnesota and upper Midwest region. The acquisition further expanded the Company’s footprint in the core Midwest region and extended its reach into new geographic markets in the upper Midwest.
See Note 3 – Acquisitions in the accompanying notes to the Company’s condensed consolidated financial statements for further information.
Operating Segments
The Company manages and measures the performance of its business in two operating segments: ODR and GCR. Segment information is prepared on the same basis that is used by the Company’s Chief Operating Decision Maker (“CODM”) to assess performance and allocate resources. The Company's CODM is comprised of its President and Chief Executive Officer and Executive Vice President and Chief Financial Officer. The Company’s CODM evaluates segment performance and makes resource allocation decisions primarily based on gross profit. Gross profit is a key measure used by the CODM in the annual budgeting and forecasting process, as well as in periodic reviews of actual operating results compared to planned performance. The CODM uses the Company's gross profit measure to assess the operating performance of its reportable segments, establish business priorities, and make decisions regarding the allocation of capital and other resources among those segments.
In accordance with ASC Topic 280 – Segment Reporting, the Company has elected to aggregate all of the ODR work performed at its branches into one ODR reportable segment and all of the GCR work performed at its branches into one GCR reportable segment. All transactions between segments are eliminated in consolidation.

•Total revenue increased by $45.9 million, or 24.9%, during the three months ended September 30, 2026 compared to the three months ended September 30, 2025. Revenue generated from the Company’s organic operations increased by
33
$26.6 million, or 14.4%. The Company’s organic revenue growth during the third quarter was driven primarily by project commencements and execution within its existing backlog. The Company expects continued execution of its backlog, together with anticipated new bookings, to support further organic revenue growth during the remainder of 2026.
During the three months ended September 30, 2026, the acquisitions of 1901 and CYMCOR contributed $19.3 million of revenue in the aggregate. Acquisition-related revenue represents revenue generated by an acquired business during the twelve-month period following its acquisition date. Thereafter, the acquired business is included within the Company's organic operations and period-over-period changes are discussed on a combined basis.
•ODR revenue increased by $9.3 million, or 6.6%, primarily due to the acquisitions of 1901 and CYMCOR, as well as organic growth. These acquisitions contributed approximately $6.2 million of ODR revenue during the three months ended September 30, 2026, while the Company’s ODR organic revenue increased approximately $3.1 million.
•GCR revenue increased by $36.6 million, or 84.7%, primarily due to a $23.5 million increase in GCR organic revenue, as well as an increase in GCR acquisition-related revenue of approximately $13.1 million attributable to the 1901 acquisition.

•Total gross profit increased by $9.2 million primarily due to higher revenue. Gross margin percentage reflected the quarter’s revenue mix, including a higher proportion of GCR revenue, which typically carries lower gross margins than ODR revenue. Segment gross margins also reflected the contribution from certain recently acquired businesses that currently operate at lower gross margin profiles than Limbach’s historical levels. These businesses currently continue to perform in line with the Company’s integration expectations, and management is implementing operational and pricing initiatives to improve profitability, with the goal of bringing their gross margins closer to the Company’s historical averages over the next two to three years.
The Company recorded revisions in its contract estimates for certain ODR and GCR projects; however, the Company did not record any material gross profit write-ups or write-downs that had a net gross profit impact of $1.0 million or more during the three months ended September 30, 2026 and 2025.

•SG&A expense increased $6.3 million, or 22.1%, which included approximately $1.2 million of aggregate SG&A expenses associated with the 1901 and CYMCOR acquisitions. Acquisition-related SG&A represents SG&A expenses incurred by an acquired business during the twelve-month period following its respective acquisition date. After such period, the results of acquired businesses are included within the Company’s organic operations, and period-over-period changes are discussed on a combined basis. The increase in organic SG&A expense was approximately $5.1
34
million, primarily driven by a $2.8 million increase in professional services expense due to the 1901 and CYMCOR acquisitions and a $2.7 million increase in payroll-related expenses, partially offset by a $0.4 million decrease in stock-based compensation expense.
•As a percentage of revenue, SG&A expense decreased to 15.0% from 15.3% in the prior-year period.
Acquisition-Related Retention Expense and Contingent Consideration
Acquisition-related retention and contingent consideration expenses were $0.6 million for both the three months ended September 30, 2026 and 2025, respectively. For the three months ended September 30, 2026 and 2025, these expenses included approximately $0.4 million and $0.3 million, respectively, of aggregate acquisition-related retention expense associated with the Pioneer Power, 1901 and CYMCOR acquisitions. In connection with these acquisitions, the Company entered into retention agreements with certain key employees of the acquired businesses. Retention-related compensation is contingent on continued employment and is recognized as expense ratably over the respective required service periods.
The Company also recognized a $0.2 million increase in the fair value of contingent consideration during the three months ended September 30, 2026, compared to a $0.3 million increase during the three months ended September 30, 2025. Changes in the fair value of contingent consideration represent non-cash expenses and were primarily attributable to updates in the estimated probability of achieving the gross profit targets underlying the related earnout arrangements.

•Total revenue increased by $82.8 million, or 18.0%, primarily due to the acquisitions of Pioneer Power, 1901 and CYMCOR, which collectively contributed $73.8 million during the nine months ended September 30, 2026. Acquisition-related revenue represents revenue generated by an acquired business during the twelve-month period following its acquisition date. Thereafter, the acquired business is included within the Company's organic operations and period-over-period changes are discussed on a combined basis. For the nine months ended September 30, 2026, acquisition-related revenue included Pioneer Power’s revenue from January 1, 2026 through June 30, 2026, and revenue from 1901 and CYMCOR from their respective acquisition dates through September 30, 2026.
Revenue generated from the Company’s organic operations increased by $9.1 million for the nine months ended September 30, 2026. The Company’s organic revenue growth was driven by project commencements and execution within its existing backlog. The Company expects to continue executing on its existing backlog, together with new bookings, to support further organic revenue growth during the remainder of 2026.
•ODR revenue increased by $38.2 million, or 11.2%, primarily due to the acquisitions of Pioneer Power, 1901 and CYMCOR, which collectively contributed approximately $43.7 million of ODR revenue during the nine months ended September 30, 2026. The Company’s organic ODR revenue decreased approximately $5.5 million.
•GCR revenue increased by $44.7 million, or 37.5% primarily due to $30.1 million of acquisition-related revenue attributable to the Pioneer Power and 1901 acquisitions, as well as a $14.6 million increase in organic GCR revenue.

| Total gross profit as a percentage of total revenue | 22.5 | % | 26.4 | % | |||||||||||||||||||
•Total gross profit increased by $1.1 million, or 0.9%, primarily due to increased revenue despite a decline in gross profit margin, reflecting a greater proportion of period-over-period GCR revenue, which typically generates lower gross margins than ODR revenue. Segment gross margins also remained below historical levels due in part to the inclusion of certain acquired businesses with historically lower gross margin profiles. These businesses continue to perform in line with the Company’s integration expectations, and management is implementing operational and pricing initiatives to improve profitability, with the goal of bringing their gross margins closer to the Company’s historical averages over the next two to three years.
•Gross profit margin was also impacted by lower net project write-ups compared to the prior year period and competition for skilled labor and materials associated with construction activity in data center markets. The Company currently expects gross profit margins to improve during the remainder of 2026; nevertheless they are expected to remain below the levels achieved during the comparable periods of 2025.
The Company recorded revisions in its contract estimates for certain ODR and GCR projects; however, the Company did not record any material gross profit write-ups or write-downs that had a net gross profit impact of $1.0 million or more during the nine months ended September 30, 2026 and 2025.

After such period, the results of acquired businesses are included within the Company’s organic operations, and period-over-period changes are discussed on a combined basis. The increase in organic SG&A expense was approximately $6.4 million, primarily due to a $4.0 million increase in payroll-related expense and a $2.0 million increase in professional services expense due to the 1901 and CYMCOR acquisitions. The remaining increase was due to various items, none of which was individually material.
•As a percentage of revenue, SG&A expense decreased to 16.7% from 17.7% in the prior-year period.
Acquisition-Related Retention Expense and Contingent Consideration
Acquisition-related retention and contingent consideration expenses were $0.9 million and $1.8 million for the nine months ended September 30, 2026 and 2025, respectively. Such expenses included approximately $0.6 million and $0.3 million, respectively, of aggregate acquisition-related retention expense associated with the Pioneer Power, 1901 and CYMCOR acquisitions. In connection with these acquisitions, the Company entered into retention agreements with certain key employees of the acquired businesses. Retention-related compensation is contingent on continued employment and is recognized as expense ratably over the respective required service periods.
In addition, the Company recognized a $0.3 million increase in the fair value of contingent consideration during the nine months ended September 30, 2026, compared to a $1.5 million increase during the nine months ended September 30, 2025. Changes in the fair value of contingent consideration represent non-cash expenses and were primarily attributable to updates to the estimated probability of achieving the gross profit targets underlying the related earnout arrangements.

•Gain on disposition of property and equipment decreased $0.7 million, reflecting normal fluctuations in asset disposal activity.
•The Company also recognized a $0.3 million loss on early debt extinguishment, reflecting the write-off of unamortized debt issuance costs and other fees associated with the termination of its former credit facility with Wintrust, compared to no such loss in the prior-year period. See Note 6 – Debt in the accompanying notes to the Company’s condensed consolidated financial statements for additional information.
Income Taxes
The Company recorded an income tax provision of $2.5 million for the nine months ended September 30, 2026 compared to $4.5 million for the nine months ended September 30, 2025. The effective tax rate was 11.9% and 14.5% for the nine months ended September 30, 2026 and 2025, respectively. The Company’s effective tax rate differed from the U.S. federal statutory tax rate in each period primarily due to state income taxes, federal tax credits, other permanent items and discrete excess tax benefits related to RSU vesting activity recognized during the first quarter of each year. See Note 10 – Income Taxes in the accompanying notes to the Company’s condensed consolidated financial statements for additional information.
ODR and GCR Backlog Information
The Company refers to its estimated revenue on uncompleted contracts, including the amount of revenue on contracts for which work has not begun, less the revenue previously recognized under such contracts, as “backlog.” Backlog includes unexercised contract options. The Company’s 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 the Company’s backlog and remaining performance obligations is due to the portion of unexercised contract options that are excluded, 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. While backlog provides a measure of work expected to be performed in future periods, it is not necessarily a reliable indicator of future revenue or overall performance of the Company.
A substantial portion of the Company’s contracts, particularly within its ODR operations, are short-cycle in nature and may be awarded and substantially completed within a short period following award. These projects typically have short lead times and rapid burn rates and, as a result, are generally not included in reported backlog. Consequently, fluctuations in reported backlog may not correlate with changes in overall market demand, revenue generation, or operational performance. Additional information related to the Company’s remaining performance obligations is provided in Note 4 – Revenue from Contracts with Customers in the accompanying notes to its condensed consolidated financial statements.
The Company’s ODR backlog was $313.4 million and $255.8 million as of September 30, 2026 and December 31, 2025, respectively. These amounts reflect unrecognized revenue expected to be recognized over the remaining terms of its construction-type and service contracts. Based on historical trends, the Company currently estimates that 44% of its ODR
39
backlog as of September 30, 2026 will be recognized as revenue over the remainder of 2026. The Company’s ODR backlog increased due to its continued growth in the Company's ODR business and the acquisitions of CYMCOR and 1901, which collectively contributed $33.2 million to ODR backlog as of September 30, 2026.
The Company’s GCR backlog was $366.1 million and $141.8 million as of September 30, 2026 and December 31, 2025, respectively. Projects are brought into backlog once the Company has been provided a written confirmation of award and the contract value has been established. At any point in time, the Company has a substantial volume of projects that are specifically identified and advanced in negotiations and/or documentation, however those projects are not booked as backlog until the Company has received written confirmation from the owner or the general contractor / construction manager of their intention to award the contract and they have directed the Company to begin engineering, designing, incurring construction labor costs or procuring needed equipment and material. The Company’s GCR projects tend to be built over a 12- to 24-month schedule depending upon scope and complexity. Most major projects have a preconstruction planning phase, which may require months of planning before actual construction commences. The Company is occasionally employed to deliver a “fast-track” project, where construction commences as the preconstruction planning work continues. As work on the Company’s projects progress, it increases or decreases backlog to take into account its estimate of the effects of changes in estimated quantities, changes in conditions, change orders and other variations from initially anticipated contract revenue, and the percentage of completion of the Company’s work on the projects. Based on historical trends, the Company currently estimates that 31% of its GCR backlog as of September 30, 2026 will be recognized as revenue over the remainder of 2026. Additionally, the increase in GCR backlog was attributable to new project awards and the acquisition of 1901, which contributed $75.3 million to GCR backlog as of September 30, 2026.
Market Update
The Company continuously monitors evolving macroeconomic conditions and heightened geopolitical risks. Economic and trade policy uncertainty has remained elevated in 2026. Trade tensions and changes in trade policy, including tariffs, global conflicts, labor disruptions, and evolving regulations may continue to contribute to inflationary pressures, supply chain disruptions, and pricing and lead-time volatility for certain materials and equipment. The Company continues to work closely with suppliers and subcontractors to mitigate potential shortages and manage supply and pricing volatility. The Company anticipates continued uncertainty with respect to inflation and other macroeconomic trends for the foreseeable future.
The Company continues to evaluate the extent to which these conditions may impact its business, financial condition, and results of operations. During periods of economic uncertainty, customers may delay or cancel large capital projects, including new construction or significant mechanical system upgrades. At the same time, demand for the Company’s service, maintenance, and repair offerings may remain stable or increase as customers prioritize maintaining existing systems over capital-intensive replacements. Economic uncertainty may also result in increased competition and pricing pressure, which could adversely affect revenue and margins. The Company believes its diversified service offerings and customer base help reduce exposure to market volatility. While the Company believes its remaining performance obligations generally represent firm commitments, project timing may shift due to customer scheduling decisions or the availability and timing of critical equipment. Prolonged delays could result in customers seeking to defer, modify, or terminate existing or pending agreements. Any of these events could have a material adverse effect on the Company’s business, financial condition, and results of operations.
The Company believes that certain of the markets in which it sources materials, equipment and, in certain instances, subcontracted services have experienced consolidation during 2026 and may continue to consolidate. Given this trend, the Company continues to actively manage its supplier and subcontractor relationships with the ultimate view and goal of providing high-quality services to its customers in an effort to be a leading building systems solutions firm.
Notwithstanding those active managerial efforts with that goal in mind, the Company understands that if it is not successful in these managerial efforts that increased consolidation among suppliers and/or subcontractors could over time impair its ability to deliver services efficiently, competitively price its offerings, or meet customer expectations.
Strategy
The Company is focused on creating value for building owners by developing long-term relationships and becoming an indispensable partner to building owners with mission-critical systems. The strategic initiatives undertaken over the past several years have strengthened the Company’s operating platform and positioned it to shift its focus from business transformation and revenue mix improvement to disciplined growth.
Building on this foundation, the Company intends to expand its business while generating strong cash flow, enhancing the durability of its earnings and delivering attractive returns over time. The Company’s strategy is centered on building enterprise scale through vertical market diversification, expanding its geographic reach and leveraging an integrated operating model
40
designed to strengthen its competitive advantages as the business grows. For additional information regarding the Company’s prior strategic initiatives, see Part I, Item 1, “Business,” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025.
Seasonality, Cyclicality and Quarterly Trends
Severe weather can impact the Company’s operations. In the northern climates where it operates, and to a lesser extent the southern climates as well, severe winters can slow the Company’s productivity on projects, which shifts revenue and gross profit recognition to a later period. The Company’s maintenance operations may also be impacted by mild or severe weather. Mild weather tends to reduce demand for its maintenance services, whereas severe weather may increase the demand for its maintenance and time and materials services. The Company’s operations also experience cyclicality, as the Company tends to see customer budgets being allocated in the first quarter of the year and an increased level of maintenance and capital project execution during the third and fourth calendar quarters of each year.
Effect of Inflation and Tariffs
The prices of key inputs used in the Company’s projects and service operations, including steel, pipe, copper, and certain equipment and components, remain subject to volatility, including increases driven by inflation, tariffs, supply constraints, and price escalation. These factors can, at times, be material to the Company’s results of operations and financial condition, particularly on fixed-price projects and where equipment lead times extend beyond procurement windows. During the nine months ended September 30, 2026, the Company continued to experience selective pricing pressure and extended lead times for certain materials and equipment, although such impacts were not material to its consolidated results of operations or financial condition.
Where appropriate, the Company seeks to mitigate these impacts by (i) incorporating cost escalation assumptions and/or escalation provisions into bids and proposals, (ii) limiting bid acceptance periods, (iii) procuring materials and equipment earlier in the project lifecycle, including through fixed-price purchase orders where feasible, and (iv) negotiating with suppliers and subcontractors to manage pricing and delivery terms. Despite these efforts, sustained inflationary pressures, supply chain disruptions, labor shortages, or rapid changes in tariff regimes could increase costs, reduce margins, and/or require the Company to defer or re-sequence projects, which could adversely affect the pace at which backlog converts to revenue.
The Company continues to monitor developments in U.S. trade policy, including tariffs imposed under Section 232 of the Trade Expansion Act of 1962 on imported steel, aluminum, and certain derivative products, as well as the potential for additional duties, exemptions, or retaliatory measures. These actions could increase costs, impact the availability and lead times of certain materials and components, and alter competitive dynamics. In the Company’s ODR segment, which generally operates on shorter sales cycles, the Company can often adjust pricing to reflect cost increases; however, it may still be unable to recover all cost increases in a timely manner, particularly for fixed-price contracts and long-lead equipment orders. Accordingly, the Company cannot predict the ultimate impact of tariffs or other trade restrictions on its business, results of operations, or financial condition.
Liquidity and Capital Resources
Cash Flows
The Company's 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.

The Company's cash flows are primarily impacted period to period by fluctuations in working capital. Factors such as the Company's contract mix, commercial terms, days sales outstanding (“DSO”) and delays in the start of projects may impact its working capital. In line with industry practice, the Company accumulates costs during a given month and then bills those costs in the current month for many of its contracts. While labor costs associated with these contracts are paid weekly and salary costs associated with the contracts are paid semi-monthly, certain subcontractor costs are generally not paid until the Company receives payment from its customers (contractual “pay-if-paid” terms). The Company has not historically experienced a large volume of write-offs related to its receivables and contract assets. The Company regularly assesses its receivables for collectability and provides allowances for credit losses where appropriate. The Company believes that its reserves for its expected credit losses are appropriate as of September 30, 2026 and December 31, 2025, but adverse changes in the economic environment may impact certain of its customers’ ability to access capital and compensate the Company for its services, as well as impact project activity for the foreseeable future.
The Company's existing backlog is projected to support a portion of forecasted revenue for one year from the date of the financial statement issuance. In addition to the Company's backlog, the Company has a substantial amount of contracts with short lead times that book-and-bill within the same reporting period and are not included in backlog. The Company's current cash balance, together with the cash it expects to generate from future operations along with borrowings available under its credit facility, are expected to be sufficient to finance its short- and long-term capital requirements (or meet working capital requirements) for at least 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 currently believes it will be able to meet any working capital and future operating requirements, and capital investment forecast opportunities for at least the next twelve months.

(1)Represents non-cash activity associated with depreciation and amortization, provision for credit losses, non-cash stock-based compensation expense, operating lease expense, amortization of debt issuance costs, deferred income tax provision, gain or loss on sale of property and equipment, acquisition-related retention expense and contingent consideration, loss on early debt extinguishment and changes in the fair value of the Company's interest rate swap.
(2)Certain prior-period operating cash flow amounts have been reclassified to conform to the current-period presentation, including the net presentation of changes in contract assets and contract liabilities and the presentation of acquisition-related retention expense and contingent consideration. These reclassifications had no impact on net cash provided by operating activities.
The Company refined the presentation of contract-related balances within operating activities by presenting changes in contract assets and contract liabilities on a net basis, rather than as separate line items, to align with the presentation of net contract positions.
During the nine months ended September 30, 2026, the Company generated $31.2 million in cash from its operating activities, which consisted of non-cash adjustments of $26.8 million and net income of $18.6 million, partly offset by cash used in working capital of $14.2 million. During the nine months ended September 30, 2025, the Company generated $17.6 million in cash from its operating activities, which consisted of net income of $26.8 million and certain non-cash adjustments of $24.1 million, partly offset by cash used in working capital of $33.3 million.
The change in operating cash flows during the nine months ended September 30, 2026 compared to the nine months ended September 30, 2025 was primarily attributable to a $17.2 million favorable change in contract assets and contract liabilities, net, reflecting the timing of billings, collections and other working capital activity. In addition, there was a $12.5 million favorable change in accounts payable, including retainage, and a $3.5 million favorable change in accrued expenses and other current liabilities due to the timing of payments. These cash inflows were partially offset by a $10.4 million unfavorable change in accounts receivable due to the timing of cash collections, a $8.2 million decrease in net income and a $2.7 million unfavorable change due to increased acquisition-related earnout payments compared to the prior-year period.
43
Cash Flows Used in Investing Activities
Cash flows used in investing activities were $96.9 million and $67.9 million for the nine months ended September 30, 2026 and 2025, respectively. Cash used in investing activities for the nine months ended September 30, 2026 included cash outflows of $66.0 million and $29.9 million associated with the 1901 Transaction and CYMCOR Transaction, respectively, net of cash acquired, and $1.8 million related to the purchase of property and equipment, partially offset by $0.7 million in proceeds from the sale of property and equipment. Cash used in investing activities for the nine months ended September 30, 2025 included a cash outflow of $65.7 million associated with the Pioneer Power Transaction, net of cash acquired, and a cash outflow of $3.6 million related to the purchase of property and equipment, which was primarily associated with the purchase of certain rental equipment to expand customer offerings. These cash outflows were partially offset by $1.3 million in proceeds from the sale of property and equipment.
Aside from the rental equipment purchases in 2025, the majority of the Company's net cash used in purchases of property plant and equipment 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 Financing Activities
Cash flows provided by financing activities were $90.3 million for the nine months ended September 30, 2026 compared to $15.2 million for the nine months ended September 30, 2025. During the nine months ended September 30, 2026, the Company borrowed $229.6 million and repaid $239.6 million under the former Wintrust revolving credit facility. In September 2026, the Company entered into the PNC Credit Agreement, with initial borrowings of $75.0 million under the PNC Revolving Credit Facility and $50.0 million under the PNC Term Loan Facility. The Company also paid approximately $1.8 million in debt issuance costs associated with the PNC Credit Agreement. See Note 6 – Debt in the accompanying notes to the Company’s condensed consolidated financial statements for additional information.
Other financing cash inflows included $5.9 million in proceeds from the sale of shares to satisfy employee tax withholding requirements and $0.6 million from employee contributions to the ESPP. Financing cash outflows included $12.0 million in tax payments related to the net share settlement of equity awards and $3.9 million in finance lease payments. Additionally, the Company made earnout payments of $3.5 million, $2.5 million and $0.9 million to the former owners of Industrial Air, Kent Island and Consolidated Mechanical, respectively, of which an aggregate of $3.5 million was classified as financing cash outflows.
During the nine months ended September 30, 2025, the Company borrowed $41.8 million under its revolving credit facility and recognized additional financing cash inflows of $6.3 million associated with the sale of shares to satisfy employee tax withholding requirements and $0.6 million from employee contributions under the ESPP. These financing cash inflows were partially offset by $17.3 million of repayments under the Company's revolving credit facility, $10.7 million in taxes paid related to the net share settlement of equity awards, $3.1 million of finance lease payments and a $3.0 million payment to the former owner of Industrial Air related to the First IA Earnout Period, of which $2.3 million was classified as a cash outflow from financing activities.

(1) The Company considers all highly liquid investments purchased with a maturity of 90 days or less on the date of purchase to be cash equivalents. Cash equivalents as of September 30, 2026 consisted of certain overnight repurchase agreements. Cash and cash equivalents exclude approximately $7.0 million of restricted cash held to collateralize outstanding letters of credit issued under the former Wintrust credit facility. Such letters of credit remain outstanding until expiration, the latest of which expires in April 2027.

(2) On September 9, 2026, LFS, LHLLC, and other designated parties entered into the PNC Credit Agreement with PNC, as administrative agent, swingline lender and issuing lender, and other lenders party thereto. The PNC Credit Agreement provides for a credit facility in an aggregate amount of up to $300.0 million in total commitments, consisting of: a revolving credit facility with an aggregate principal amount of $200.0 million, including a $20.0 million swingline loan subfacility and a $25.0 million letter of credit subfacility, a term loan facility with an aggregate principal amount of $50.0 million and a delayed draw term loan facility with aggregate commitments of $50.0 million. See Note 6 – Debt to the condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q for additional information regarding the PNC Credit Facility.
(3) The Company intends to deploy free cash flow to reduce borrowings under the PNC Revolving Credit Facility, subject to its liquidity, capital allocation and operating requirements.
(4) Represents the portion of unused borrowing capacity under the PNC Revolving Credit Facility and PNC Delayed Draw Term Loan Facility that was unavailable to the Company as of September 30, 2026 due to the requirement to maintain compliance with the maximum Consolidated Net Leverage Ratio under the PNC Credit Agreement. This amount is based on the Company's covenant calculation as of September 30, 2026 and assumes that proceeds from any additional borrowings are used for purposes that do not increase cash included in the covenant calculation. Actual borrowing availability may vary based on the Company's financial performance, the use of borrowing proceeds, and other conditions under the PNC Credit Agreement.
Cash Flow Summary
Management continued to devote additional resources to its billing and collection efforts during the nine months ended September 30, 2026. Management continues to expect that growth in the Company's ODR business, which is less sensitive to the cash flow issues presented by large GCR projects, together with a more selective approach to pursuing GCR projects, will positively impact the Company's cash flow trends.
On September 9, 2026, the Company entered into the PNC Credit Agreement, which provides for aggregate commitments of up to $300.0 million, including a $200.0 million revolving credit facility, a $50.0 million term loan facility and a $50.0 million delayed draw term loan facility. The Company believes the new credit facility enhances its liquidity and financial flexibility and increases its available borrowing capacity to support its operating requirements. See Note 6 – Debt to the condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q for additional information regarding the PNC Credit Facility.
Based on its current forecast, the Company believes that its cash and cash equivalents of $29.1 million as of September 30, 2026, cash flows expected to be generated from operations and available borrowing capacity under the PNC Revolving Credit Facility and PNC DDTL Facility of $125.0 million and $50.0 million, respectively, as of September 30, 2026, subject to applicable borrowing conditions and continued compliance with the financial covenants under the PNC Credit Agreement, are expected to be sufficient to meet its working capital needs, capital expenditure requirements and other liquidity requirements for at least the next 12 months. Of the combined $175.0 million in unused commitments, approximately $39.9 million was unavailable due to financial covenant limitations, resulting in approximately $135.1 million of available borrowing capacity as of September 30, 2026.

Surety Bonding
In connection with its business, the Company is occasionally required to provide various types of surety bonds that provide an additional measure of security to its customers for its performance under certain government and private sector contracts. The Company’s ability to obtain surety bonds depends upon its 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 the Company’s backlog that it has currently bonded and their current underwriting standards, which may change from time-to-time. The bonds, if any, the Company provides typically reflect the contract value. As of September 30, 2026 and December 31, 2025, the Company had approximately $121.6 million and $156.6 million in surety bonds outstanding, respectively. The Company believes that its $1.0 billion bonding capacity provides us with a significant competitive advantage relative to many of its competitors, which we believe have limited bonding capacity. See Note 13 – Commitments and Contingencies to the condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q for additional information.
Insurance and Self-Insurance
The Company purchases 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. The Company accrues 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 consolidated balance sheets as current and non-current liabilities. The liability is determined by establishing 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.
The Company is also self-insured related to medical and dental claims under policies with annual per-claimant and annual aggregate stop-loss limits. The Company accrues 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. See Note 13 – Commitments and Contingencies to the condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q for additional information.
Multiemployer Pension Plans
The Company participates in approximately 80 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, the Company is responsible with the other participating employers for any plan underfunding. The Company’s 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 its 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 the Company 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.
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.
The Company could also be obligated to make payments to MEPPs if it either ceases to have an obligation to contribute to the MEPP or significantly reduces its contributions to the MEPP because it reduces 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 the Company’s proportionate share of the MEPPs’ unfunded vested benefits. The Company believes that certain of the MEPPs in which it participates may have unfunded vested benefits. Due to uncertainty regarding future factors that could trigger withdrawal liability, the Company is unable to determine (a) the amount and timing of any future withdrawal liability, if any,
46
and (b) whether its participation in these MEPPs could have a material adverse impact on its financial condition, results of operations or liquidity.
Critical Accounting Policies and Estimates
Management’s Discussion and Analysis of Financial Condition and Results of Operations are based upon our condensed consolidated financial statements, which have been prepared in accordance with GAAP. The preparation of the condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements for assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, the reported amounts of revenue and expenses during the reported period, and the accompanying notes. Management believes that its most significant estimates and assumptions have been based on reasonable and supportable assumptions and the resulting estimates are reasonable for use in the preparation of the condensed consolidated financial statements. The Company’s significant estimates include estimates associated with revenue recognition on construction contracts, costs incurred through each balance sheet date, intangibles, property and equipment, fair value accounting for acquisitions, insurance reserves, income tax valuation allowances, fair value of contingent consideration arrangements and contingencies. If the underlying estimates and assumptions upon which the condensed consolidated financial statements are based change in the future, actual amounts may differ from those included in the accompanying consolidated financial statements.
Management believes there have been no significant changes during the nine months ended September 30, 2026, to the items that we disclosed as our critical accounting policies and estimates in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and Note 2 – Significant Accounting Policies in the accompanying notes to the Company’s consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2025.
Recent Accounting Pronouncements
See Note 2 – Summary of Significant Accounting Policies in the accompanying notes to the Company’s condensed consolidated financial statements for a discussion of recent accounting pronouncements.
Item 3. Quantitative and Qualitative Disclosures About Market Risk
Interest Rate Risk
The Company is exposed to market risk through changes in interest rates on its variable-rate borrowings under the PNC Credit Agreement. Borrowings under the PNC Revolving Credit Facility and PNC Term Loan Facility bear interest, at the Company’s election, at either the Base Rate or Term SOFR, plus an applicable margin. As of September 30, 2026, the Company had $75.0 million and $50.0 million of borrowings outstanding under the PNC Revolving Credit Facility and PNC Term Loan Facility, respectively.
In September 2026, the Company repaid and terminated its former Wintrust credit facility and terminated the related interest rate swap arrangement. Accordingly, as of September 30, 2026, the Company had no outstanding interest rate swap arrangements to mitigate its exposure to changes in interest rates. See Note 6 – Debt to the condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q for additional information regarding the PNC Credit Facility.
Assuming outstanding borrowing balances remain constant, a hypothetical 100 basis point increase in interest rates applicable to the Company’s variable-rate debt as of September 30, 2026 would result in an approximately $1.3 million increase in annualized interest expense. Conversely, a 100 basis point decrease in interest rates would result in a comparable decrease in annualized interest expense, subject to applicable interest rate floors. Actual results could differ from these estimates due to fluctuations in borrowing levels and other factors. See Note 6 – Debt to the condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q for additional information.
In addition, the Company considers all highly liquid investments purchased with a maturity of 90 days or less on the date of purchase to be cash equivalents. Cash and cash equivalents as of September 30, 2026 were $29.1 million. The Company maintains a disciplined cash management strategy, generally using available cash to reduce outstanding borrowings under the PNC Revolving Credit Facility while maintaining sufficient liquidity to support operating requirements. Excess cash may be invested in overnight repurchase agreements. For both the three and nine months ending September 30, 2026, interest income in the aggregate was approximately $0.1 million. The Company maintains a conservative investment policy and has not experienced any losses in its cash and cash equivalents. Management believes the Company is not exposed to significant risk with respect to such accounts.
Item 4. Controls and Procedures
47
Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures
Our management, with the participation of our President and Chief Executive Officer and Executive Vice President 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 September 30, 2026, our President and Chief Executive Officer and Executive Vice President 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.
Part II
Item 1. Legal Proceedings
See Note 13 – Commitments and Contingencies to the condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q for information regarding legal proceedings, which information is incorporated herein by reference.
Item 1A. Risk Factors
The financial condition and results of operations of the Company may be affected by a number of factors, whether currently known or unknown, including, but not limited to, those described under “Item 1A. Risk Factors” in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025. These risks could materially and adversely affect the Company’s business, financial condition, cash flows, and results of operations. The Company may also be subject to additional risks and uncertainties that are not currently known or that, due to future developments, may become material.
Except for the risk factor disclosed in Part II, Item 1A of the Company’s Quarterly Report on Form 10-Q for the quarter ended March 31, 2026, which is incorporated herein by reference, there have been no material changes to the risk factors disclosed in the 2025 Annual Report.
