PART I. FINANCIAL INFORMATION
DEFINITIONS
In this Quarterly Report on Form 10-Q, the words “IES”, the “Company”, the “Registrant”, “we”, “our”, “ours” and “us” refer to IES Holdings, Inc. and, except as otherwise specified herein, to our subsidiaries.
DISCLOSURE REGARDING FORWARD-LOOKING STATEMENTS
This Quarterly Report on Form 10-Q includes certain statements that may be deemed “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, all of which are based upon various estimates and assumptions that the Company believes to be reasonable as of the date hereof. In some cases, you can identify forward-looking statements by terminology such as “may,” “will,” “could,” “should,” “expect,” “plan,” “project,” “intend,” “anticipate,” “believe,” “seek,” “estimate,” “predict,” “potential,” “pursue,” “target,” “continue,” the negative of such terms or other comparable terminology. These statements involve risks and uncertainties that could cause the Company’s actual future outcomes to differ materially from those set forth in such statements. Such risks and uncertainties include, but are not limited to:
•a general reduction in the demand for our products or services;
•changes in general economic conditions, including supply chain constraints, high rates of inflation, tariffs, changes in consumer sentiment, elevated interest rates, and market disruptions resulting from a number of factors, including geo-political events such as the Ukraine-Russia war, the conflict in the Middle East, and trade tensions between the U.S. and China;
•competition in the industries in which we operate, both from third parties and former employees, which could result in the loss of one or more customers or lead to lower margins on new projects;
•our ability to successfully manage and execute projects, the cost and availability of qualified labor and the ability to maintain positive labor relations, and our ability to pass along increases in the cost of commodities used in our business, in particular, copper, aluminum, steel, fuel, electronic components and certain plastics;
•our ability to enter into, and the terms of, future contracts;
•the existence of a small number of customers from whom we derive a meaningful portion of our revenues;
•reliance on third parties, including subcontractors and suppliers, to complete our projects;
•the inability to carry out plans and strategies as expected, including the inability to identify and complete acquisitions that meet our investment criteria in furtherance of our corporate strategy, or the subsequent underperformance of those acquisitions;
•challenges integrating new businesses into the Company or new types of work, products or processes into our segments;
•backlog that may not be realized or may not result in profits;
•failure to adequately recover on contract change orders or claims against customers;
•closures or sales of our facilities resulting in significant future charges, including potential warranty losses or other unexpected liabilities, or a significant disruption of our operations;
•the impact of future epidemics or pandemics on our business, including the potential for new or continued job site closures or work stoppages, supply chain disruptions, delays in awarding new project bids, construction delays, reduced demand for our services, delays in our ability to collect from our customers, or illness of management or other employees;
•an increased cost of surety bonds affecting margins on work and the potential for our surety providers to refuse bonding or require collateral at their discretion;
•the impact of seasonality, adverse weather conditions, and climate change;
•fluctuations in operating activity due to factors such as cyclicality, downturns in levels of construction or the housing market, and differing regional economic conditions;
•difficulties in managing our billings and collections;
•accidents resulting from the physical hazards associated with our work and the potential for accidents;
3

•the possibility that our current insurance coverage may not be adequate or that we may not be able to obtain policies at acceptable rates;
•the effect of litigation, claims and contingencies, including warranty losses, damages or other latent defect claims in excess of our existing reserves and accruals;
•costs and liabilities under existing or potential future laws and regulations, including those laws and regulations related to the environment and climate change, as well as the inability to transfer, renew and obtain electrical and other professional licenses;
•interruptions to our information systems and cybersecurity or data breaches;
•expenditures to conduct environmental remediation activities required by certain environmental laws and regulations;
•loss of key personnel, ineffective transition of new management, or general labor constraints;
•credit and capital market conditions, including changes in interest rates that affect the cost of construction financing and mortgages, and the inability of some of our customers to obtain sufficient financing at acceptable rates, which could lead to project delays or cancellations;
•limitations on our ability to access capital markets and generate cash from operations to fund our working capital needs and capital expenditures, to complete acquisitions, and for debt service;
•the impact on our effective tax rate or cash paid for taxes from changes in tax positions we have taken or changes in tax laws;
•difficulty in fulfilling the covenant terms of our revolving credit facility, which could result in a default and acceleration of any indebtedness under such revolving credit facility;
•reliance on certain estimates and assumptions that may differ from actual results in the preparation of our financial statements;
•uncertainties inherent in the use of percentage-of-completion accounting, which could result in the reduction or elimination of previously recorded revenues and profits;
•the recognition of potential goodwill, long-lived assets and other investment impairments;
•the existence of a controlling shareholder, who has the ability to take action not aligned with other shareholders or to dispose of all or a significant portion of the shares of our common stock it holds, which may trigger certain change of control provisions in a number of our material agreements, including our financing and surety arrangements and our executive severance plan;
•the relatively low trading volume of our common stock, which could increase the volatility of our stock price and could make it more difficult for shareholders to sell a substantial number of shares for the same price at which shareholders could sell a smaller number of shares;
•the possibility that we issue additional shares of common stock, preferred stock or convertible securities that will dilute the percentage ownership interest of existing stockholders and may dilute the value per share of our common stock;
•the potential for substantial sales of our common stock, which could adversely affect our stock price;
•the impact of increasing scrutiny and changing expectations from investors and customers, or new or changing regulations, with respect to environmental, social and governance practices;
•the cost or effort required for our shareholders to bring certain claims or actions against us, as a result of our designation of the Court of Chancery of the State of Delaware as the sole and exclusive forum for certain types of actions and proceedings;
•the possibility that our internal controls over financial reporting and our disclosure controls and procedures may not prevent all possible errors that could occur; and
•other factors discussed elsewhere in this Quarterly Report on Form 10-Q.
You should understand that the foregoing, as well as other risk factors discussed in this document, including those listed in Part I, Item 1A of our Annual Report on Form 10-K for the fiscal year ended September 30, 2024, could cause future outcomes to differ materially from those experienced previously or those expressed in such forward-looking statements. We undertake no obligation to publicly update or revise any information, including information concerning our controlling shareholder, borrowing availability or cash position, or any forward-looking statements to reflect events or circumstances that may arise after the date of this report. Forward-looking statements are provided in this Quarterly Report on Form 10-Q pursuant to the safe harbor established under the Private Securities Litigation Reform Act of 1995 and should be evaluated in the context of the estimates, assumptions, uncertainties and risks described herein.

IES HOLDINGS, INC. AND SUBSIDIARIES
Notes to the Condensed Consolidated Financial Statements
(All Amounts in Thousands Except Share Amounts)
(Unaudited)
1. BUSINESS AND ACCOUNTING POLICIES
Description of the Business
IES Holdings, Inc. designs and installs integrated electrical and technology systems and provides infrastructure products and services to a variety of end markets, including data centers, residential housing and commercial and industrial facilities. Our operations are organized into four business segments, based upon the nature of our services:
•Communications – Nationwide provider of technology infrastructure services, including the design, build, and maintenance of the communications infrastructure within data centers for co-location and managed hosting customers, for both large corporations and independent businesses.
•Residential – Regional provider of electrical installation services for single-family housing and multi-family apartment complexes, as well as heating, ventilation and air conditioning (HVAC) and plumbing installation services in certain markets.
•Infrastructure Solutions – Provider of electro-mechanical solutions for industrial operations, including apparatus repair and custom-engineered products such as generator enclosures used in data centers and other industrial applications.
•Commercial & Industrial – Provider of electrical and mechanical design, construction, and maintenance services to the commercial and industrial markets in various regional markets and nationwide in certain areas of expertise, such as the power infrastructure market and data centers.
The words “IES”, the “Company”, “we”, “our”, and “us” refer to IES Holdings, Inc. and, except as otherwise specified herein, to our consolidated subsidiaries.
Seasonality and Quarterly Fluctuations
Results of operations from our Residential segment can be seasonal, depending on weather trends, with typically higher revenues generated during spring and summer and lower revenues generated during fall and winter. The Commercial & Industrial, Communications and Infrastructure Solutions segments of our business are less subject to seasonal trends, as work in these segments generally is performed inside structures protected from the weather, although weather can still impact these businesses, especially in the early stages of projects. From quarter to quarter, results for our Communications, Residential, and Commercial & Industrial segments may be materially affected by the timing of new construction projects, and our volume of business may be adversely affected by declines in construction projects resulting from adverse regional or national economic conditions. Quarterly results for our Infrastructure Solutions segment may be affected by the timing of outages or capital projects at our customers’ facilities. Accordingly, operating results for any fiscal period are not necessarily indicative of results that may be achieved for any subsequent fiscal period.
Basis of Financial Statement Preparation
The accompanying unaudited Condensed Consolidated Financial Statements include the accounts of IES, our wholly-owned subsidiaries, and entities that we control due to ownership of a majority of voting interest and have been prepared in accordance with the instructions to interim financial reporting as prescribed by the United States Securities and Exchange Commission (the “SEC”). The results for the interim periods are not necessarily indicative of results for the entire year. These interim financial statements do not include all disclosures required by U.S. generally accepted accounting principles (“GAAP”) and should be read in conjunction with the consolidated financial statements and notes thereto filed with the SEC in our Annual Report on Form 10-K for the fiscal year ended September 30, 2024. In the opinion of management, the unaudited Condensed Consolidated Financial Statements contained in this report include all known accruals and adjustments necessary for a fair presentation of the financial position, results of operations, and cash flows for the periods reported herein. Any such adjustments are of a normal recurring nature.
Income Taxes
On July 4, 2025, the U.S. enacted the One Big Beautiful Bill Act (“Act”), a comprehensive legislative package that includes significant changes to federal tax policy. The Act, among other corporate provisions, includes the permanent extension of 100% bonus depreciation and the repeal of mandatory capitalization of domestic research and experimental expenditures. The Company is currently assessing the impact the Act will have on our overall financial results, financial position, and cash flows.
Equity Method Investments
We account for investments using the equity method of accounting if the investment gives us the ability to exercise significant influence over an investee but does not grant us control. Significant influence generally exists when an investor owns 20% or more of
10

the voting stock of an incorporated investee or a more than 3% to 5% interest in an unincorporated investee. Under the equity method of accounting, the carrying amount of an investment is initially recorded at cost basis and is subsequently adjusted for our proportionate share of earnings or losses, additional investments in the entity, and distributions. Our proportionate share of earnings or losses is recorded in earnings on our Condensed Consolidated Statements of Comprehensive Income.
Noncontrolling Interest
In connection with our acquisitions of Edmonson Electric, LLC (“Edmonson Electric”) and Bayonet Plumbing, Heating & Air-Conditioning, LLC (“Bayonet”) in fiscal 2021, and NEXT Electric, LLC in fiscal 2017, we acquired an 80 percent interest in each of the entities, with the remaining 20 percent interest in each such entity being retained by the respective third-party seller. The interests retained by those third-party sellers are identified on our Condensed Consolidated Balance Sheets as “Noncontrolling interest,” classified outside of permanent equity. On June 28, 2024, we acquired the remaining 20 percent noncontrolling interest in Bayonet for $32,000.
Under the terms of each entity’s operating agreement, after five years from the date of the acquisition, we may elect to purchase, or the third-party seller may require us to purchase, part or all of the remaining 20 percent interest in the applicable entity. In each case, the purchase price is variable, based on a multiple of earnings as defined in the applicable operating agreement. Therefore, each noncontrolling interest is carried at the greater of the balance determined under Accounting Standards Codification (“ASC”) 810 and the redemption amounts assuming the noncontrolling interest was redeemable at the balance sheet date. If all of the noncontrolling interests remaining outstanding at June 30, 2025 had been redeemable at that date, the aggregate redemption amount would have been $40,977.
The activity in redeemable noncontrolling interest for the nine months ended June 30, 2025 and 2024 is summarized in the table below.

| Nine Months Ended June 30,
| 2025 |  | 2024
Balance at beginning of period | $ | 40,996 |  |  | $ | 49,951 |
Net income attributable to noncontrolling interests | 5,375 |  |  | 11,062 |
Distributions to noncontrolling interests | (7,536) |  |  | (14,474) |
Adjustments to record noncontrolling interests at redemption value | 2,142 |  |  | 21,260 |
Adjustment to record noncontrolling interests at value of consideration paid to acquire ownership interest | — |  |  | 3,120 |
Purchase of ownership interest from noncontrolling interests | — |  |  | (32,000) |
Balance at end of period | $ | 40,977 |  |  | $ | 38,919 |

On July 1, 2025, we acquired the remaining 20 percent noncontrolling interest in Edmonson Electric for $40,000.
Use of Estimates
The preparation of financial statements in conformity with GAAP requires the use of estimates and assumptions by management in determining the reported amounts of assets and liabilities, disclosures of contingent liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Estimates are primarily used in our revenue recognition of construction in progress, fair value assumptions in accounting for business combinations, stock-based compensation, reserves for legal matters, and realizability of deferred tax assets and unrecognized tax benefits.
Accounting Standards Recently Adopted
In October 2021, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update No. 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers (“ASU 2021-08”). This standard amends the existing guidance under ASC 805 to add contract assets and contract liabilities to the list of exceptions to the recognition and measurement principles that apply to business combinations. Under this standard, the acquirer of a business is expected to recognize and measure acquired contract assets and contract liabilities as if the acquirer entered into the original contract on the same date with the same terms in accordance with ASC 606 rather than at fair value on the date of acquisition. This update is effective for fiscal years beginning after December 15, 2022 and for interim periods within that year. We adopted this standard on October 1, 2023 using the prospective method. ASU 2021-08 impacts how we account for business combinations completed after its adoption.

Recent Accounting Pronouncements and Disclosure Rules Not Yet Adopted
In November 2023, the FASB issued Accounting Standard Update No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (“ASU 2023-07”). This standard requires disclosure of significant segment expenses, other segment items, and additional information about the chief operating decision maker (“CODM”). This update is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted, and retrospective application is required. We are evaluating the impact this update will have on our annual disclosures; however, it will not impact our financial condition, results of operations, or cash flows.
In December 2023, the FASB issued Accounting Standard Update No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”). This standard requires more detailed disclosure within the tax rate reconciliation table, as well as additional information about cash taxes paid. This update is effective for fiscal years beginning after December 15, 2024. Early adoption is permitted. We are evaluating the impact this update will have on our annual disclosures; however, it will not impact our financial condition, results of operations, or cash flows.
In November 2024, the FASB issued Accounting Standard Update No. 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses (“ASU 2024-03”). This standard requires additional disclosures of certain expenses, including purchases of inventory, employee compensation, depreciation, intangible asset amortization, and other specific expense categories. This standard also requires disclosure of the total amount of selling expenses and the Company's definition of selling expenses. This update is effective for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027. Early adoption is permitted. We are evaluating the impact this update will have on our annual disclosures; however, it will not impact our financial condition, results of operations, or cash flows.
2. CONTROLLING STOCKHOLDER
Tontine Associates, L.L.C. (“Tontine Associates”), together with its affiliates (collectively, “Tontine”), is the Company’s controlling stockholder, owning approximately 55 percent of the Company’s outstanding common stock based on a Form 4 filed by Tontine with the SEC on June 13, 2025 and the Company's shares outstanding as of July 31, 2025. Accordingly, Tontine has the ability to exercise significant control over our affairs, including the election of directors and most actions requiring the approval of stockholders.
While Tontine is subject to certain restrictions under federal securities laws on sales of its shares as an affiliate, the Company has filed a shelf registration statement to register all of the shares of IES common stock owned by Tontine at the time of registration. As long as the shelf registration statement remains effective and the Company remains eligible to use it, Tontine has the ability to resell any or all of its registered shares from time to time in one or more offerings, as described in the shelf registration statement and in any prospectus supplement filed in connection with an offering pursuant to the shelf registration statement.
Should Tontine sell or otherwise dispose of all or a significant portion of its position in IES, a change in control of IES could occur. A change of control would trigger the change of control provisions in a number of our material agreements, including our credit agreement, bonding agreements with our sureties and our executive severance plan.
Jeffrey L. Gendell was appointed as Chief Executive Officer of the Company effective October 1, 2020, having served as the Company's Interim Chief Executive Officer since July 31, 2020. Mr. Gendell also serves as Chairman of the Board of Directors, a position he has held since November 2016. Effective July 1, 2025, Mr. Gendell transitioned from Chief Executive Officer to Executive Chairman. He is the managing member and founder of Tontine, and the brother of David B. Gendell, who has served as a member of our Board of Directors since February 2012, and who previously served as Interim Director of Operations from November 2017 to January 2019, as Vice Chairman of the Board from November 2016 to November 2017 and as Chairman of the Board from January 2015 to November 2016. David B. Gendell was an employee of Tontine from 2004 until January 2018.
The Company is party to a sublease agreement with Tontine Associates for corporate office space in Greenwich, Connecticut. On August 1, 2024, the Company entered into an amendment of the sublease agreement, which was set to terminate on August 31, 2024, to extend the term of the agreement through September 30, 2025 effective September 1, 2024, while maintaining monthly payments due in the amount of approximately $9. Payments by the Company are at a rate consistent with that paid by Tontine Associates to its landlord.
On December 6, 2018, the Company entered into a Board Observer Letter Agreement (the "Observer Agreement") with Tontine Associates in order to assist Tontine in managing its investment in the Company. Subject to the terms and conditions set forth in the Observer Agreement, the Company granted Tontine the right, at any time that Tontine holds at least 20% of the outstanding common stock of the Company, to appoint a representative to serve as an observer to the Board (the “Board Observer”). The Board Observer, who must be reasonably acceptable to those members of the Board who are not affiliates of Tontine, shall have no voting rights or other decision making authority. Subject to the terms and conditions set forth in the Observer Agreement, so long as Tontine has the
12

right to appoint a Board Observer, the Board Observer will have the right to attend and participate in meetings of the Board and the committees thereof, subject to confidentiality requirements, and to receive reimbursement for reasonable out-of-pocket expenses incurred in his or her capacity as a Board Observer and such rights to coverage under the Company’s directors’ and officers’ liability insurance policy as are available to the Company’s directors.
3. REVENUE RECOGNITION
Contracts
Our revenue is derived from contracts with customers, and we determine the appropriate accounting treatment for each contract at its inception. Our contracts primarily relate to electrical and mechanical contracting services, technology infrastructure products and services, and electro-mechanical solutions for industrial operations. Revenue is earned based upon an agreed fixed price or actual costs incurred plus an agreed upon percentage.
We account for a contract when: (i) it has approval and commitment from both parties, (ii) the rights of the parties are identified, (iii) payment terms are identified, (iv) the contract has commercial substance, and (v) collectability of consideration is probable. We consider the start of a project to be when the above criteria have been met and we have written authorization from the customer to proceed.
Performance Obligations
A performance obligation is a promise in a contract to transfer a distinct good or service to the customer. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. Given the nature of the Company's services, our contracts with customers have historically been comprised of a single performance obligation.
We recognize revenue over time for the majority of the services we perform as (i) control continuously transfers to the customer as work progresses at a project location controlled by the customer and (ii) we have the right to bill the customer as costs are incurred. Within our Infrastructure Solutions Custom Engineered Solutions business, we often perform work inside our own facilities, where control does not continuously transfer to the customer as work progresses. In such cases, we evaluate whether the work performed creates an asset with alternative use to the Company and whether we have the right to bill the customer as costs are incurred. Where we are creating an asset with no alternative use and we have a contractual right to payment for work performed to date, we recognize revenue over time. If we do not have such a right, we recognize revenue upon completion of the contract, when control of the work transfers to the customer.
For arrangements where we recognize revenue over time, we generally use the percentage of completion method of accounting under which revenue recognized is measured principally by the costs incurred and accrued to date for each contract as a percentage of the estimated total cost for each contract at completion. Contract costs include all direct material, labor and indirect costs related to contract performance. Changes in job performance, job conditions, estimated contract costs and profitability and final contract settlements may result in revisions to costs and income, and the effects of these revisions are recognized in the period in which the revisions are determined. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are determined. This measurement and comparison process requires updates to the estimate of total costs to complete the contract, and these updates may include subjective assessments and judgments. Certain divisions in the Residential and Infrastructure Solutions segments recognize revenue under the right to invoice practical expedient because the duration of their contracts is short. We recognize revenue on such contracts when amounts are billable to the customer, generally when the project is complete.
Variable Consideration
The transaction price for our contracts may include variable consideration, which includes changes to transaction price for approved and unapproved change orders, claims and incentives. Change orders, claims, and incentives are generally not distinct from the existing contract due to the significant integration service provided in the context of the contract and are accounted for as a modification of the existing contract. We estimate variable consideration at the probability weighted value we expect to receive (or the most probable amount we expect to incur in the case of liquidated damages, if any), utilizing estimation methods that best predict the amount of consideration to which we will be entitled (or will be incurred in the case of liquidated damages, if any). We include variable consideration in the estimated transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur or when the uncertainty associated with the variable consideration is resolved. Our estimates of variable consideration and determination of whether to include estimated amounts in transaction price are based largely on an assessment of our anticipated performance and all information (historical, current and forecasted) that is reasonably available to us. The effect of variable consideration on the transaction price of a performance obligation is recognized as an adjustment to revenue on a cumulative catch-up basis. To the extent unapproved change orders and claims reflected in transaction price (or accounted for as a reduction of the transaction price in the case of liquidated damages) are not resolved in our favor, or to the extent incentives reflected in transaction price are not earned, there could be reductions in, or reversals of, previously recognized revenue.

Disaggregation of Revenue
We disaggregate our revenue from contracts with customers by activity and contract type, as these categories reflect how the nature, amount, timing and uncertainty of our revenue and cash flows are affected by economic factors. Our consolidated revenue for the three and nine months ended June 30, 2025 and 2024 was derived from the following activities. Certain prior period amounts have been reclassified to conform with the current period presentation, where applicable. See details in the following tables:

Accounts Receivable
Accounts receivable include amounts that we have billed or have an unconditional right to bill our customers. As of June 30, 2025, Accounts receivable included $13,639 of unbilled receivables for which we have an unconditional right to bill.
Contract Assets and Liabilities
Project contracts typically provide for a schedule of billings on percentage of completion of specific tasks inherent in the fulfillment of our performance obligation(s). The schedules for such billings usually do not precisely match the schedule on which costs are incurred. As a result, contract revenue recognized in the statement of operations can and usually does differ from amounts that can be billed to the customer at any point during the contract. Amounts by which cumulative contract revenue recognized on a contract as of a given date exceeds cumulative billings and unbilled receivables to the customer under the contract are reflected as a current asset in our Condensed Consolidated Balance Sheets under the caption “Costs and estimated earnings in excess of billings”. Amounts by which cumulative billings to the customer under a contract as of a given date exceed cumulative contract revenue recognized are reflected as a current liability in our Condensed Consolidated Balance Sheets under the caption “Billings in excess of costs and estimated earnings”.
During the nine months ended June 30, 2025 and 2024, we recognized revenue of $145,991 and $96,889 related to our contract liabilities at September 30, 2024 and 2023, respectively.
Remaining Performance Obligations
Remaining performance obligations represent the unrecognized revenue value of our contract commitments. New awards represent the total expected revenue value of new contract commitments undertaken during a given period, as well as additions to the scope of existing contract commitments. Our new performance obligations vary significantly each reporting period based on the timing of our major new contract commitments. At June 30, 2025, we had remaining performance obligations of $1,295,207. The Company expects to recognize revenue on approximately $940,247 of the remaining performance obligations over the next 12 months, with the remainder recognized thereafter.
For the three and nine months ended June 30, 2025, net revenue recognized from our performance obligations satisfied in previous periods was not material.
4. DEBT
Prior to January 21, 2025, we were a party to the Third Amended and Restated Credit and Security Agreement (the “Third Credit Agreement”), which provided for a maximum borrowing amount of $150,000 under our revolving credit facility. Borrowings were limited by a borrowing base determined based on available collateral. The Third Credit Agreement, which was scheduled to mature on September 30, 2026, contained customary affirmative, negative and financial covenants.
Fourth Amended and Restated Credit and Security Agreement
On January 21, 2025 we entered into the Fourth Amended and Restated Credit Agreement (the “Amended Credit Agreement”). Pursuant to the Amended Credit Agreement, our revolver amount increased from $150,000 to $300,000, and the maturity date was extended from September 30, 2026, to January 21, 2030. In addition, the limitation on borrowings based on available collateral was eliminated under the Amended Credit Agreement.
Under the Amended Credit Agreement, the Company is subject to certain financial covenants including a maximum Consolidated Total Leverage Ratio (as defined in the Amended Credit Agreement) of 3.00 to 1.00 and a minimum Consolidated Interest Coverage Ratio (as defined in the Amended Credit Agreement) of 3.00 to 1.00. As of June 30, 2025, the Company was in compliance with the financial covenants under the Amended Credit Agreement.
At June 30, 2025, we had $20,000 in borrowings under our revolving credit facility, and we had no outstanding borrowings under our revolving credit facility at September 30, 2024. At June 30, 2025, we had $5,545 in outstanding letters of credit and our total availability under the revolving credit facility was $274,455.
15

Amounts outstanding bear interest at a rate equal to either (1) the Base Rate (which is the greater of the Federal Funds Rate (as defined in the Amended Credit Agreement) and the Prime Rate (as defined in the Amended Credit Agreement)), (2) the Daily Simple SOFR (as defined in the Amended Credit Agreement) or (3) Term SOFR (as defined in the Amended Credit Agreement), plus, in each case, an interest rate margin, which is determined quarterly based on our Consolidated Total Leverage Ratio, in accordance with the following thresholds:

Pricing Level |  | Consolidated Total Leverage Ratio |  | Interest Margin applicable to Daily Simple SOFR/Term SOFR |  | Interest Margin applicable to Base Rate
I |  | Greater than or equal to 2.50 to 1.00 |  | 2.25 percentage points |  | 1.25 percentage points
II |  | Greater than or equal to 1.75 to 1.00, but less than 2.50 to 1.00 |  | 2.00 percentage points |  | 1.00 percentage points
III |  | Greater than or equal to 1.00 to 1.00, but less than 1.75 to 1.00 |  | 1.75 percentage points |  | 0.75 percentage points
IV |  | Less than 1.00 to 1.00 |  | 1.50 percentage points |  | 0.50 percentage points

In addition, we are charged monthly in arrears for an unused commitment fee of 0.25% to 0.35% per annum on any unused portion of the revolving credit facility based on the Company's Consolidated Total Leverage Ratio.
The Amended Credit Agreement restricts certain types of transactions when the Company’s Consolidated Total Leverage Ratio, after giving pro forma effect thereto, exceeds 2.75 to 1.00. The Amended Credit Agreement continues to contain other customary affirmative and negative covenants as well as events of default.
5. PER SHARE INFORMATION

For the three and nine months ended June 30, 2024, the average price of our common shares exceeded the exercise price of all of our outstanding stock options. As a result, all of our outstanding stock options were included in the computation of diluted earnings per share. We had no remaining outstanding unvested stock options during the three and nine months ended June 30, 2025.
6. OPERATING SEGMENTS
We manage and measure performance of our business in four distinct operating segments: Communications, Residential, Infrastructure Solutions, and Commercial & Industrial. These segments are reflective of how the Company's CODM reviews operating results for the purpose of allocating resources and assessing performance. The Company’s CODM is its Chief Executive Officer.
16

Transactions between segments, if any, are eliminated in consolidation. Our corporate office provides general and administrative services, as well as support services, to each of our four operating segments. Management allocates certain shared costs among segments for selling, general and administrative expenses and depreciation expense.
Segment information for the three and nine months ended June 30, 2025 and 2024 is as follows:

7. STOCKHOLDERS’ EQUITY
Equity Incentive Plan
The Company’s 2006 Equity Incentive Plan, as amended and restated (the “Equity Incentive Plan”), provides for grants of phantom stock units, performance awards and stock options as well as grants of stock, including restricted stock. The Equity Incentive Plan was amended and restated effective February 20, 2025 following approval by stockholders at the Company's 2025 Annual Meeting of Stockholders to, among other things, authorize the issuance of an additional 750,000 shares under the Equity Incentive Plan and extend its term to February 19, 2035. As of June 30, 2025, approximately 3.75 million shares of common stock were authorized for issuance under the Equity Incentive Plan, of which approximately 1,265,795 shares were available for issuance.
Stock Repurchase Program
On July 31, 2024, our Board authorized a stock repurchase program for the purchase from time to time of up to $200,000 of the Company’s common stock after the previous stock repurchase program was fully utilized. Share purchases are made for cash in open market transactions at prevailing market prices or in privately negotiated transactions or otherwise. The timing and amount of purchases under the program are determined based upon prevailing market conditions, our liquidity requirements, contractual restrictions and other factors. All or part of the repurchases may be implemented under a Rule 10b5-1 trading plan, which allows repurchases under predetermined terms at times when the Company might otherwise be prevented from purchasing under insider trading laws or because of self-imposed blackout periods. The program does not require the Company to purchase any specific number of shares and may be modified, suspended, reinstated, or terminated at any time at the Company’s discretion and without notice. We repurchased 33,900 and 173,262 shares of our common stock during the three and nine months ended June 30, 2025 in open market transactions at an average price of $157.16 and $174.25 per share, respectively. We repurchased 157,505 shares of our common stock during the three and nine months ended June 30, 2024 in open market transactions at an average price of $132.92.
Treasury Stock
During the nine months ended June 30, 2025, we issued 94,752 shares of common stock from treasury stock to employees and repurchased 38,744 shares of common stock from our employees to satisfy statutory tax withholding requirements upon the vesting of certain phantom stock units under the Equity Incentive Plan.
During the nine months ended June 30, 2024, we issued 82,180 shares of common stock from treasury stock to employees and repurchased 33,940 shares of common stock from our employees to satisfy statutory tax withholding requirements upon the vesting of certain phantom stock units under the Equity Incentive Plan. During the nine months ended June 30, 2024, we issued 1,000 unrestricted shares to satisfy the exercise of certain outstanding option awards under the Equity Incentive Plan.
Director Phantom Stock Units
Director phantom stock units (“Director PSUs”) are granted to the members of the Board of Directors as part of their overall compensation. The Director PSUs are contractual rights to receive one share of the Company's common stock and are paid via unrestricted stock grants to each director upon their departure from the Board of Directors, or upon a change in control. We record compensation expense for the full value of the grant on the date of grant.
18

Employee Phantom Stock Units
An employee phantom stock unit (an “Employee PSU”) is a contractual right to receive one share of the Company’s common stock. Depending on the terms of each grant, Employee PSUs may vest upon the achievement of certain specified performance objectives and continued performance of services, or may vest based on continued performance of services through the vesting date.
A summary of Employee PSU activity for the nine months ended June 30, 2025 is provided in the table below:

Unvested at September 30, 2024 | 300,301 |

8. INVESTMENTS
Investments in Marketable Securities
Investments in marketable equity and debt securities classified as trading securities, which were included in “Marketable securities” in our Condensed Consolidated Balance Sheets, are measured at fair value on a recurring basis and classified within Level 1 of the fair value hierarchy, because we use quoted prices of identical assets in active markets. For more information, refer to Note 9, “Fair Value Measurements.” The balance of our marketable securities was as follows:

| June 30, 2025 |  | September 30, 2024
Marketable equity securities | $ | 66,815 |  |  | $ | 31,639 |
Marketable debt securities | — |  |  | 3,364 |
Marketable securities | $ | 66,815 |  |  | $ | 35,003 |

Gains and losses to measure our investments in marketable equity and debt securities at fair value were included in “Other (income) expense, net” on our Condensed Consolidated Statements of Comprehensive Income. Our unrealized net gains (losses), which are calculated as total net gains (losses) recognized during the period less net gains (losses) recognized on securities sold during the period, were as follows:

| Three Months Ended June 30, |  | Nine Months Ended June 30,
| 2025 |  | 2024 |  | 2025 |  | 2024
Unrealized gain (loss) on marketable equity securities | $ | (3,764) |  |  | $ | (1,497) |  |  | $ | 4,098 |  |  | $ | (3,349) |
Unrealized gain (loss) on marketable debt securities | — |  |  | (55) |  |  | — |  |  | 7 |
Total unrealized gain (loss) on trading securities | $ | (3,764) |  |  | $ | (1,552) |  |  | $ | 4,098 |  |  | $ | (3,342) |

Equity Method Investments
On December 2, 2024, we paid $44,900 to acquire a 12.5% membership interest in Jett Texas Company LLC (“Jett”), an investment company, as part of the financing of Jett's investment in the CB&I storage solutions business, a designer and builder of storage facilities, tanks and terminals for energy and industrial markets, formerly owned by McDermott International, Ltd. Our investment, which was included in “Investments” on our Condensed Consolidated Balance Sheets, is measured using the equity method of accounting, wherein the carrying value of our investment is initially recorded at cost basis and subsequently adjusted for our proportionate share of earnings or losses, additional investments, and distributions. We recorded no earnings or loss on our investment in Jett in the three and nine months ended June 30, 2025 and the carrying value of our investment in Jett was $44,900 at June 30, 2025.

9. FAIR VALUE MEASUREMENTS
Fair Value Measurement Accounting
Fair value is considered the price to sell an asset, or transfer a liability, between market participants on the measurement date. Fair value measurements assume that (1) the asset or liability is exchanged in an orderly manner, (2) the exchange is in the principal market for that asset or liability, and (3) the market participants are independent, knowledgeable, and able and willing to transact an exchange. Fair value accounting and reporting establishes a framework for measuring fair value by creating a hierarchy for observable independent market inputs and unobservable market assumptions and expands disclosures about fair value measurements. Judgment is required to interpret the market data used to develop fair value estimates. As such, the estimates presented herein are not necessarily indicative of the amounts that could be realized in a current exchange. The use of different market assumptions and/or estimation methods could have a material effect on the estimated fair value.
The carrying values of cash and cash equivalents, restricted cash, accounts receivable, accounts payable, and contract assets and liabilities approximate fair values due to their short-term nature. The carrying value of borrowings under our revolving credit facility approximates fair value as its effective interest rate is variable and approximates market rates.
At June 30, 2025 and September 30, 2024, financial assets and liabilities measured at fair value on a recurring basis were limited to investments in marketable equity and debt securities classified as trading securities, our executive savings plan, under which certain employees are permitted to defer a portion of their base salary and/or bonus for a Plan Year (as defined in the plan), and contingent consideration liabilities related to certain of our acquisitions.
Financial assets (liabilities) measured at fair value on a recurring basis as of June 30, 2025 and September 30, 2024, are summarized in the following tables by the type of inputs applicable to the fair value measurements:

| June 30, 2025
|  |  | Total Fair Value |  |  | Quoted Prices (Level 1) |  |  | Significant Unobservable Inputs (Level 3)

Total |  | $ | 31,669 |  |  | $ | 35,137 |  |  | $ | (3,468) |

On April 1, 2024, we entered into a contingent consideration arrangement under which we are obligated to pay up to $5,000 upon achievement of certain future earnings targets in connection with the acquisition of Greiner Industries, Inc. (“Greiner”) valued at $2,790 on the acquisition date. The fair value of this liability, which was included in “Other non-current liabilities” in our Condensed Consolidated Balance Sheets, is measured on a recurring basis classified within Level 3 of the fair value hierarchy. Net adjustments to its fair value were included in “Contingent consideration” in our Condensed Consolidated Statements of Comprehensive Income.
The table below presents the change in fair value of liabilities measured using significant unobservable inputs (Level 3).

12. COMMITMENTS AND CONTINGENCIES
Legal Matters
From time to time, we are a party to various claims, lawsuits and other legal proceedings that arise in the ordinary course of business. We maintain various insurance coverages to minimize financial risk associated with these proceedings. None of these proceedings, separately or in the aggregate, are expected to have a material adverse effect on our financial position, results of operations or cash flows. With respect to all such proceedings, we record reserves when it is probable that a liability has been incurred and the amount of loss can be reasonably estimated. We expense routine legal costs related to these proceedings as they are incurred.

In the course of performing work as a subcontractor, from time to time we may be involved in projects which are the subject of contractual disputes between the general contractor and project owner, or between us and the general contractor. In such cases, payment of amounts owed to us by the general contractor may be delayed as contractual disputes are resolved through mediation, arbitration, or litigation. Such disputes may cause us to incur legal fees and other expenses to enforce our contractual rights, and we may not prevail in recovering all amounts to which we believe we are contractually entitled.
Risk Management
We retain the risk for workers’ compensation, employer’s liability, automobile liability, construction defects, general liability and employee group health claims, as well as pollution coverage, resulting from uninsured deductibles per accident or occurrence which are generally subject to annual aggregate limits. Our general liability program provides coverage for bodily injury and property damage. In many cases, we insure third parties, including general contractors, as additional insured parties under our insurance policies. Losses are accrued based upon our known claims incurred and an estimate of claims incurred but not reported. As a result, many of our claims are effectively self-insured. Many claims against our insurance are in the form of litigation. At June 30, 2025 and September 30, 2024, we had $11,435 and $11,158, respectively, accrued for self-insurance liabilities. Because the reserves are based on judgment and estimates and involve variables that are inherently uncertain, such as the outcome of litigation and an assessment of insurance coverage, there can be no assurance that the ultimate liability will not be higher or lower than such estimates.
Some of the underwriters of our casualty insurance program require us to post letters of credit as collateral. This is common in the insurance industry. To date, we have not had a situation where an underwriter has had reasonable cause to effect payment under a letter of credit. At June 30, 2025 and September 30, 2024, $5,545 and $4,756, respectively, of our outstanding letters of credit was utilized to collateralize our insurance program.
Surety
As of June 30, 2025, the estimated cost to complete our bonded projects was approximately $142,193. We evaluate our bonding requirements on a regular basis, including the terms offered by our sureties. We believe the bonding capacity presently provided by our current sureties is adequate for our current operations and will be adequate for our operations for the foreseeable future.
Other Commitments and Contingencies
Some of our customers and vendors require us to post letters of credit, or provide intercompany guarantees, as a means of guaranteeing performance under our contracts and ensuring payment by us to subcontractors and vendors. If our customer has reasonable cause to effect payment under a letter of credit, we would be required to reimburse our creditor for the letter of credit.
From time to time, we may enter into firm purchase commitments for materials, such as copper or aluminum wire, which we expect to use in the ordinary course of business. These commitments are typically for terms of less than one year and require us to buy minimum quantities of materials at specific intervals at a fixed price over the term. As of June 30, 2025, we did not have any such firm commitments to purchase materials outstanding.
13. SUPPLEMENTAL CASH FLOW INFORMATION
The following provides a reconciliation of the components of cash, cash equivalents and restricted cash to the amounts reported on our Condensed Consolidated Balance Sheets as of June 30, 2025 and September 30, 2024, which sum to the amounts shown in our Condensed Consolidated Statements of Cash Flows for the nine months ended June 30, 2025.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations
The following discussion and analysis should be read in conjunction with our Consolidated Financial Statements and the notes thereto, set forth in Part II, Item 8. “Financial Statements and Supplementary Data” as set forth in our Annual Report on Form 10-K for the fiscal year ended September 30, 2024, and the Condensed Consolidated Financial Statements and notes thereto included in Part I, Item 1 of this Quarterly Report on Form 10-Q. The following discussion may contain forward looking statements. For additional information, see “Disclosure Regarding Forward Looking Statements” in Part I of this Quarterly Report on Form 10-Q.
OVERVIEW
Executive Overview
Please refer to Part I, Item 1. “Business” of our Annual Report on Form 10-K for the fiscal year ended September 30, 2024, for a discussion of the Company’s services and corporate strategy. IES Holdings, Inc., a Delaware corporation, designs and installs integrated electrical and technology systems and provides infrastructure products and services to a variety of end markets, including data centers, residential housing, and commercial and industrial facilities. Our operations are organized into four business segments: Communications, Residential, Infrastructure Solutions and Commercial & Industrial.
Current Market and Operating Conditions
Throughout the first nine months of fiscal 2025, our business has benefited from strong demand continuing across many of our key end markets. However, our business segments each have their own unique set of factors influencing demand for our services. Housing affordability challenges from elevated mortgage rates and inflation, as well as the impact of overall economic uncertainty on consumer confidence, have persisted throughout the spring and into the summer, which is typically an active time for home sales. In response to this, many large home builders have increased their offerings of customer incentives as they focus on maintaining volume through fluctuations in consumer demand. These incentives have put pressure on our revenues and gross margins in our single-family business. Current tariff policy could exacerbate these housing affordability and consumer confidence issues, which could further impact our single-family business. In the multi-family residential business, higher borrowing costs for project owners during fiscal 2024 resulted in a reduction in backlog entering fiscal 2025, which in turn drove a reduction in multi-family residential revenues for fiscal 2025 to date. Backlog across our business segments as a whole remains high, reflecting strong demand in key end markets. Demand with respect to data centers, a key end market served by our Communications, Infrastructure Solutions, and Commercial & Industrial segments, remains particularly strong. However, availability of labor and capacity could constrain the rate at which we are able to grow our business in this end market.
RESULTS OF OPERATIONS
We report our operating results across our four operating segments: Communications, Residential, Infrastructure Solutions, and Commercial & Industrial. Expenses associated with our corporate office are classified separately. The following table presents selected historical results of operations of IES Holdings, Inc., including the results of acquired businesses from the dates acquired.

Consolidated revenues for the three months ended June 30, 2025, were $121.7 million higher than for the three months ended June 30, 2024, an increase of 15.8%, with increases at our Communications, Infrastructure Solutions and Commercial & Industrial segments and a decrease at our Residential segment. See further discussion below of changes in revenues for our individual segments.
Consolidated gross profit for the three months ended June 30, 2025 increased $44.8 million compared to the three months ended June 30, 2024. Our overall gross profit percentage was 26.9% during the three months ended June 30, 2025, as compared to 25.3% during the three months ended June 30, 2024. Gross profit as a percentage of revenue increased at our Communications, Residential and Infrastructure Solutions segments and decreased at our Commercial & Industrial segment. See further discussion below of changes in gross margin for our individual segments.
Selling, general and administrative expenses include costs not directly associated with performing work for our customers. These costs consist primarily of compensation and benefits related to corporate, segment and branch management (including incentive-based compensation), occupancy and utilities, training, professional services, information technology costs, consulting fees, travel and certain types of depreciation and amortization. We allocate certain corporate selling, general and administrative costs across our segments as we believe this more accurately reflects the costs associated with operating each segment.
During the three months ended June 30, 2025, our selling, general and administrative expenses were $127.3 million, an increase of $22.6 million, or 21.6%, over the three months ended June 30, 2024, driven by increased personnel costs across our operating segments to support their growth and increased incentive compensation in connection with higher earnings than in the prior fiscal year. As a percentage of revenue, selling, general and administrative expenses increased from 13.6% for the three months ended June 30, 2024 to 14.3% for the three months ended June 30, 2025.

During the three months ended June 30, 2025, we incurred interest expense of $0.5 million primarily comprised of interest on our finance lease agreements and fees on an average letter of credit balance of $5.5 million under our revolving credit facility and an average unused line of credit balance of $292.2 million. This compares to interest expense of $0.4 million for the three months ended June 30, 2024, primarily comprised of interest on our finance lease agreements and fees on an average letter of credit balance of $5.6 million under our revolving credit facility and an average unused line of credit balance of $142.9 million.
The increase in total other expense, net for the three months ended June 30, 2025, compared to the three months ended June 30, 2024 is primarily the result of unrealized losses on investments in trading securities of $3.8 million in the three months ended June 30, 2025 compared to unrealized losses of $1.6 million on investments in trading securities in the three months ended June 30, 2024.

During the nine months ended June 30, 2025, we incurred interest expense of $1.3 million primarily comprised of interest on our finance lease agreements and fees on an average letter of credit balance of $5.5 million under our revolving credit facility and an average unused line of credit balance of $233.3 million. This compares to interest expense of $1.2 million for the nine months ended June 30, 2024, primarily comprised of interest on our finance lease agreements and fees on an average letter of credit balance of $5.5 million under our revolving credit facility and an average unused line of credit balance of $142.7 million.

The change in total other (income) expense, net for the nine months ended June 30, 2025, compared with June 30, 2024 is primarily the result of unrealized gains on investments in trading securities of $4.1 million in the nine months ended June 30, 2025 compared to unrealized losses on investments in trading securities of $3.3 million in the nine months ended June 30, 2024, partially offset by a decrease in interest income from $3.3 million in the nine months ended June 30, 2024 to $2.1 million in the nine months ended June 30, 2025.
PROVISION FOR INCOME TAXES
We recorded income tax expense of $29.5 million for the three months ended June 30, 2025, compared to $22.6 million for the three months ended June 30, 2024, driven primarily by increased pretax income.
We recorded income tax expense of $75.5 million for the nine months ended June 30, 2025, compared to $57.3 million for the nine months ended June 30, 2024, driven primarily by increased pretax income.
CRITICAL ACCOUNTING POLICIES AND ESTIMATES
Management’s discussion and analysis of financial condition and results of operations is based on our Condensed Consolidated Financial Statements included in this Quarterly Report on Form 10-Q, which have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”). The preparation of our Condensed Consolidated Financial Statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities known to exist as of the date of the Condensed Consolidated Financial Statements, and the reported amounts of revenues and expenses recognized during the periods presented. We review all significant estimates affecting our Condensed Consolidated Financial Statements on a recurring basis and record the effect of any necessary adjustments prior to their publication. Judgments and estimates are based on our beliefs and assumptions derived from information available at the time such judgments and estimates are made. Uncertainties with respect to such estimates and assumptions are inherent in the preparation of financial statements. There can be no assurance that actual results will not differ from those estimates. For a discussion of our significant accounting policies, please see our Annual Report on Form 10-K for the fiscal year ended September 30, 2024. Some of the more significant estimates include revenue recognition, business combinations, and income taxes.
There have been no significant changes to our accounting policies as disclosed in our Annual Report on Form 10-K for the fiscal year ended September 30, 2024.
REMAINING PERFORMANCE OBLIGATIONS AND BACKLOG
Remaining performance obligations represent the unrecognized revenue value of our contractual commitments. While backlog is not a defined term under GAAP, it is a common measurement used in our industry, and we believe it improves our ability to forecast future results and identify operating trends that may not otherwise be apparent. Backlog is a measure of revenue that we expect to recognize from work that has yet to be performed on uncompleted contracts and from work that has been contracted but has not started, exclusive of short-term projects. While all of our backlog is supported by documentation from customers, backlog is not a guarantee of future revenues, as contractual commitments may change and our performance may vary. Not all of our work is performed under contracts included in backlog; for example, most of the apparatus repair work that is completed by our Infrastructure Solutions segment is performed under master service agreements on an as-needed basis. Additionally, electrical, plumbing and HVAC installation services for single-family housing at our Residential segment are completed on a short-term basis and are therefore excluded from backlog. The table below summarizes our remaining performance obligations and backlog (in thousands):

|  | June 30, |  | March 31, |  | December 31, |  | September 30,
|  | 2025 |  | 2025 |  | 2024 |  | 2024
Remaining performance obligations |  | $ | 1,295,207 |  |  | $ | 1,225,985 |  |  | $ | 1,214,828 |  |  | $ | 1,175,695 |

(1) Our backlog contains signed agreements and letters of intent, which we do not have a legal right to enforce prior to work starting. These arrangements are excluded from remaining performance obligations until work begins.

WORKING CAPITAL
During the nine months ended June 30, 2025, working capital exclusive of cash, cash equivalents and restricted cash increased by $109.6 million from September 30, 2024, reflecting a $133.6 million increase in current assets excluding cash partially offset by a $24.0 million increase in current liabilities during the period.
During the nine months ended June 30, 2025, our current assets exclusive of cash, cash equivalents and restricted cash increased to $904.5 million, as compared to $770.9 million as of September 30, 2024. The increase was primarily driven by a $74.4 million
31

increase in accounts receivable including retainage due to higher overall volume of sales and the timing of customer billings and project execution at the end of the period. Marketable securities also increased by $31.8 million as a portion of our excess cash was invested in trading securities. In addition, costs and estimated earnings in excess of billings increased by $14.6 million, driven by the timing of contract billings, and inventory increased by $7.0 million primarily due to the acquisition of Arrow during the nine months ended June 30, 2025.
During the nine months ended June 30, 2025, our total current liabilities increased by $24.0 million to $546.6 million, compared to $522.6 million as of September 30, 2024, primarily driven by a $28.2 million increase in accounts payable and accrued expenses as our volume of sales increased.
Surety
We believe the bonding capacity provided by our sureties is adequate for our current operations and will be adequate for our operations for the foreseeable future. As of June 30, 2025, the estimated cost to complete our bonded projects was approximately $142.2 million.
LIQUIDITY AND CAPITAL RESOURCES
The Revolving Credit Facility
On January 21, 2025 we entered into the Fourth Amended and Restated Credit Agreement (the “Amended Credit Agreement”). Pursuant to the Amended Credit Agreement, our maximum revolver amount increased from $150 million to $300 million, and the maturity date was extended from September 30, 2026 to January 21, 2030. In addition, the limitation on borrowings based on available collateral under the previous credit agreement was eliminated under the Amended Credit Agreement.
Under the Amended Credit Agreement, the Company is subject to certain financial covenants including a maximum Consolidated Total Leverage Ratio (as defined in the Amended Credit Agreement) of 3.00 to 1.00 and a minimum Consolidated Interest Coverage Ratio (as defined in the Amended Credit Agreement) of 3.00 to 1.00. As of June 30, 2025, the Company was in compliance with the financial covenants under the Amended Credit Agreement.
Amounts outstanding bear interest at a rate equal to either (1) the Base Rate (which is the greater of the Federal Funds Rate (as defined in the Amended Credit Agreement) and the Prime Rate (as defined in the Amended Credit Agreement)), (2) the Daily Simple SOFR (as defined in the Amended Credit Agreement) or (3) Term SOFR (as defined in the Amended Credit Agreement), plus, in each case, an interest rate margin, which is determined quarterly based on our Consolidated Total Leverage Ratio, in accordance with the following thresholds:

Pricing Level |  | Consolidated Total Leverage Ratio |  | Interest Margin applicable to Daily Simple SOFR/Term SOFR |  | Interest Margin applicable to Base Rate
I |  | Greater than or equal to 2.50 to 1.00 |  | 2.25 percentage points |  | 1.25 percentage points
II |  | Greater than or equal to 1.75 to 1.00, but less than 2.50 to 1.00 |  | 2.00 percentage points |  | 1.00 percentage points
III |  | Greater than or equal to 1.00 to 1.00, but less than 1.75 to 1.00 |  | 1.75 percentage points |  | 0.75 percentage points
IV |  | Less than 1.00 to 1.00 |  | 1.50 percentage points |  | 0.50 percentage points

In addition, we are charged monthly in arrears for an unused commitment fee of 0.25% to 0.35% per annum on any unused portion of the revolving credit facility based on the Company's Consolidated Total Leverage Ratio.
The Amended Credit Agreement restricts certain types of transactions when the Company’s Consolidated Total Leverage Ratio, after giving pro forma effect thereto, exceeds 2.75 to 1.00. The Amended Credit Agreement continues to contain other customary affirmative and negative covenants as well as events of default.
Under the Amended Credit Agreement, if in the future our Consolidated Total Leverage Ratio is greater than 3.00:1.00, or our Consolidated Interest Coverage Ratio is less than 3.00:1.00, or if we otherwise fail to perform or otherwise comply with certain of our covenants or other agreements under the Amended Credit Agreement, it would result in an event of default under the Amended Credit Agreement, which could result in some or all of our then-outstanding indebtedness becoming immediately due and payable.
At June 30, 2025, we had $5.5 million in outstanding letters of credit and $20.0 million of outstanding borrowings under our revolving credit facility.

Operating Activities
Our cash flow from operations is not only influenced by cyclicality, demand for our services, operating margins and the type of services we provide, but can also be influenced by working capital needs such as the timing of our receivable collections. Working capital needs are generally lower during our fiscal first and second quarters due to the seasonality that we experience in many regions of the country; however, a seasonal decline in working capital may be offset by needs associated with higher growth or acquisitions. Currently, our working capital needs are higher than they have been historically, as a result of growth of our business and elevated commodity prices.
Net cash provided by operating activities was $154.1 million during the nine months ended June 30, 2025, as compared to $141.6 million in the nine months ended June 30, 2024. The increase in operating cash flow resulted from increased earnings in the nine months ended June 30, 2025, partially offset by an increase in cash used in working capital, including $26.9 million of investments, net of sales, in marketable securities securities, during the nine months ended June 30, 2025 as compared with the nine months ended June 30, 2024.
Investing Activities
Net cash used in investing activities was $114.1 million for the nine months ended June 30, 2025, compared to $96.4 million used in investing activities in the nine months ended June 30, 2024. During the nine months ended June 30, 2025, we paid $44.9 million to acquire a membership interest in Jett Texas Company LLC (“Jett”), an investment company, as part of the financing of Jett's investment in the CB&I storage solutions business formerly owned by McDermott International, Ltd. We also made capital expenditures of $47.3 million as we continued to purchase new assets instead of entering into new lease agreements at our Communications segment and made other capital expenditures to support the growth of our business. Additionally, we paid $22.6 million in conjunction with business combinations, primarily related to the acquisition of Arrow in January 2025. During the nine months ended June 30, 2024, we completed the acquisition of Greiner for $67.7 million and used $30.9 million for capital expenditures to support the growth of our business.
Financing Activities
Net cash used in financing activities for the nine months ended June 30, 2025 was $32.4 million, compared to $76.1 million for the nine months ended June 30, 2024. Net cash used in financing activities for the nine months ended June 30, 2025 included $41.6 million used to repurchase our common stock, including repurchases to satisfy statutory withholding requirements upon the vesting of employee stock compensation, and $7.5 million in distributions to noncontrolling interests under operating agreements in connection with certain acquisitions. Net cash used in financing activities for the nine months ended June 30, 2024 included $31.2 million paid to acquire the noncontrolling interest in Bayonet, $24.3 million used to repurchase our common stock, including repurchases to satisfy statutory withholding requirements upon the vesting of employee stock compensation, $13.5 million in distributions to noncontrolling interests under operating agreements in connection with certain acquisitions, and $4.1 million to settle our contingent consideration liability related to prior year acquisitions.
Stock Repurchase Program
On July 31, 2024, our Board authorized a stock repurchase program for the purchase from time to time of up to $200.0 million of the Company’s common stock after the previous stock repurchase program was fully utilized. Share purchases are made for cash in open market transactions at prevailing market prices or in privately negotiated transactions or otherwise. The timing and amount of purchases under the program are determined based upon prevailing market conditions, our liquidity requirements, contractual restrictions and other factors. All or part of the repurchases may be implemented under a Rule 10b5-1 trading plan, which allows repurchases under pre-set terms at times when the Company might otherwise be prevented from purchasing under insider trading laws or because of self-imposed blackout periods. The program does not require the Company to purchase any specific number of shares and may be modified, suspended, reinstated, or terminated at any time at the Company’s discretion and without notice. We repurchased 173,262 shares pursuant to our repurchase programs during the nine months ended June 30, 2025.
MATERIAL CASH REQUIREMENTS
From time to time, we may enter into firm purchase commitments for materials, such as copper or aluminum wire, which we expect to use in the ordinary course of business. These commitments are typically for terms of less than one year and require us to buy minimum quantities of materials at specific intervals at a fixed price over the term. As of June 30, 2025, we did not have any such firm commitments to purchase materials outstanding. In connection with expected growth in our business, we are planning to expand capacity in certain areas. In the second quarter of fiscal 2025 we updated our capital expenditure expectations for the current fiscal year to a range of $70 million to $80 million, compared to $45.2 million for the year ended September 30, 2024. There have been no other material changes in our material cash requirements from those disclosed in our Annual Report on Form 10-K for the fiscal year ended September 30, 2024. We expect that cash and cash equivalents, cash flow from operations and availability under our revolving
33

credit facility will be sufficient to satisfy cash requirements during at least the next 12 months.

Item 3. Quantitative and Qualitative Disclosures About Market Risk
Management is actively involved in monitoring exposure to market risk and continues to develop and utilize appropriate risk management techniques. Our exposure to significant market risks includes fluctuations in labor costs and commodity prices. We are also exposed to interest rate risk with respect to any debt obligations we may incur our revolving credit facility. For additional information see “Disclosure Regarding Forward-Looking Statements” in Part I of this Quarterly Report on Form 10-Q and our risk factors in Part I, Item 1A. “Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended September 30, 2024.
Commodity Risk
Our exposure to significant market risks includes fluctuations in commodity prices for, among other things, copper, aluminum, steel, electrical components, certain plastics, and fuel. Commodity price risks may have an impact on our results of operations due to the fixed-price nature of many of our contracts. Over the long term, we expect to be able to pass along a portion of these costs to our customers, as market conditions in the industries we serve will allow.
Investment Risk
We are exposed to market price volatility for our investments in marketable securities which are carried at fair value measured using market prices, with gains and losses included in “Other expense, net” on our Condensed Consolidated Statements of Comprehensive Income. Changes in the market value of these investments could create volatility in our reported earnings from period to period, and a decline in value of our investments could have an adverse impact on our reported earnings. Changes in market value of these investments measured at fair value resulted in an unrealized gain of $4.1 million in the nine months ended June 30, 2025. As of June 30, 2025, we had investments in marketable securities with a fair value of $66.8 million, and a 10% increase or decrease in the market value of these investments would cause a $6.7 million increase or decrease, respectively, to the carrying value of our investments in marketable securities and our pre-tax income. The hypothetical 10% increase or decrease does not represent the maximum extent to which the fair value of our investments could be affected by changes in market conditions. Our investments could decline in value by a far greater amount as a result of volatility in the equity markets and the concentrated nature of our investment portfolio.
Interest Rate Risk
Floating rate debt, where the interest rate fluctuates periodically, exposes us to short-term changes in market interest rates. Any long-term debt that may be outstanding from time to time under our revolving credit facility is structured on floating rate terms. We currently do not maintain any hedging contracts that would limit our exposure to variable rates of interest when we have outstanding borrowings under our revolving credit facility. Under the Amended Credit Agreement, we have the option to use SOFR as the benchmark for establishing the interest rate charged on our borrowings. If we choose to use SOFR to establish the interest rate on our borrowings and SOFR were to increase, our interest payment obligations on any then-outstanding borrowings would increase, having a negative effect on our cash flow and financial condition. A one percentage point increase in the interest rate on our long-term debt outstanding under the credit facility as of June 30, 2025 would cause a $0.2 million pre-tax annual increase in interest expense.
Item 4. Controls and Procedures
Changes in Internal Control Over Financial Reporting
There have been no changes in the Company’s internal control over financial reporting (as such term is defined in Rules 13a-15 and 15d-15 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) during the fiscal quarter to which this report relates that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting. In the fiscal year ended September 30, 2024, we began planning and preparing for our phased implementation of a new enterprise resource planning (“ERP”) system, which will replace and upgrade many of our existing financial systems and processes. The ERP system is designed to accurately maintain our financial records and provide timely information to management to be used in operating the business. The first phase was implemented in the quarter ended December 31, 2024 and the Company has continued working toward the next phase of the implementation throughout the second and third quarters of fiscal 2025. Upon the first phase implementation, the Company updated its internal controls as appropriate. As the implementation activities take place, we will continue to monitor the impact of the implementation on our financial reporting business processes and evaluate each quarter whether there are changes that affect our internal control over financial reporting.
Disclosure Controls and Procedures
In accordance with Rules 13a-15 and 15d-15 of the Exchange Act, we carried out an evaluation, under the supervision and with the participation of management, including our Chief Executive Officer and our Chief Financial Officer, of the effectiveness of our disclosure controls and procedures as of the end of the period covered by this report. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of June 30, 2025, to provide reasonable assurance that information required to be disclosed in our reports filed or submitted under the Exchange Act is
35

recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms. Our disclosure controls and procedures include controls and procedures designed to ensure that information required to be disclosed in reports filed or submitted under the Exchange Act is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.
