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 market and macro-economic disruptions resulting from Russia's invasion of Ukraine or other geo-political events;

•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 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;

•supply chain disruptions due to our suppliers' access to materials and labor, their ability to ship products timely, or credit or liquidity problems they may face;

•the impact of the novel coronavirus (“COVID-19”) pandemic or any 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, the impact of third party vaccine mandates on employee recruiting and retention, or illness of management or other employees;

•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 retain sufficient financing, which could lead to project delays or cancellations;

•inaccurate estimates used when entering into fixed-price contracts, the possibility of errors when estimating revenue and progress to date on percentage-of-completion contracts, and complications associated with the incorporation of new accounting, control and operating procedures;

•our ability to enter into, and the terms of, future contracts;

•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 seasonality, adverse weather conditions, and climate change;

•an increased cost of surety bonds affecting margins on work and the potential for our surety providers to refuse bonding or require additional collateral at their discretion;

•fluctuations in operating activity due to downturns in levels of construction or the housing market, seasonality and differing regional economic conditions;

•increases in bad debt expense and days sales outstanding due to liquidity problems faced by our customers;

•accidents resulting from the physical hazards associated with our work and the potential for accidents;

•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;

•interruptions to our information systems and cyber security or data breaches;

•liabilities under existing or potential future laws and regulations, including those laws and regulations related to the environment and climate change;

•expenditures to comply with future changes in laws and regulations, including environmental laws and regulations and those relating to climate change;

•loss of key personnel, ineffective transition of new management, or inability to transfer, renew and obtain electrical and other professional licenses;

•the possibility that the value of certain tax benefits may be reduced by a decrease in the federal tax rate;

•the recognition of tax benefits related to uncertain tax positions and the potential for disagreements with taxing authorities with regard to tax positions we have adopted;

•the potential recognition of valuation allowances or write-downs on deferred tax assets;

•limitations on the availability of sufficient credit or cash flow to fund our working capital needs and capital expenditures, to complete acquisitions, and for debt service;

•difficulty in fulfilling the covenant terms of our revolving credit facility, including liquidity, and other financial requirements, which could result in a default and acceleration of any indebtedness under such revolving credit facility;

•uncertainties inherent in estimating future operating results, including revenues, operating income or cash flow;

•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 any portion of the shares of our common stock it holds, which could 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 may 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, resulting from 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, 2023, 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, net operating losses, 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.

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, 2023. 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.

Noncontrolling Interest

In connection with our acquisitions of Edmonson Electric, LLC 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. 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. The purchase price is variable, based on a multiple of earnings as defined in the operating agreements. Therefore, this noncontrolling interest is carried at the greater of the balance determined under Accounting Standards Codification (“ASC”) 810 and the redemption

amounts assuming the noncontrolling interests were redeemable at the balance sheet date. If all of the noncontrolling interests remaining outstanding at December 31, 2023 had been redeemable at that date, the redemption amount would have been $54,969.

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 will impact how we account for future business combinations.

2. CONTROLLING STOCKHOLDER

Tontine Associates, L.L.C. (“Tontine Associates”), together with its affiliates (collectively, “Tontine”), is the Company’s controlling stockholder, owning approximately 57 percent of the Company’s outstanding common stock based on a Form 4 filed by Tontine with the SEC on January 24, 2024 and the Company's shares outstanding as of January 31, 2024. 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 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. 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. In December 2022, the Company entered into an amendment of the sublease agreement, which was set to terminate on February 28, 2023, to extend the term of the agreement through August 31, 2024 and to increase the monthly payments from approximately $8 to approximately $9 effective March 1, 2023. 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 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.

We recognize revenue over time for the majority of the services we perform other than the Residential Single-family and Infrastructure Solutions Industrial Services businesses, 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 Power 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. Such assessment involves an evaluation of contractual termination clauses. 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 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.

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 and performance obligation. We estimate variable consideration for a performance obligation 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 which 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 months ended December 31, 2023 and 2022 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:


	Three Months Ended December 31,
	2023		2022
Communications	$	170,748	$	147,245
Residential
Single-family	246,567		243,710

Total revenue		$	147,245	$	318,078	$	49,284	$	60,267	$	574,874

Accounts Receivable and Allowance for Credit Losses

Accounts receivable include amounts that we have billed or have an unconditional right to bill our customers. As of December 31, 2023, Accounts receivable included $5,347 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 Sheet 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 Sheet under the caption “Billings in excess of costs and estimated earnings”.

During the three months ended December 31, 2023 and 2022, we recognized revenue of $77,964 and $38,047 related to our contract liabilities at October 1, 2023 and 2022, 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 December 31, 2023, we had remaining performance obligations of $1,072,593. The Company expects to recognize revenue on approximately $872,321 of the remaining performance obligations over the next 12 months, with the remainder recognized thereafter.

For the three months ended December 31, 2023, net revenue recognized from our performance obligations satisfied in previous periods was not material.

4. DEBT

We are a party to the Third Amended and Restated Credit and Security Agreement (the “Amended Credit Agreement”), which provides for a maximum borrowing amount of $150,000 under our revolving credit facility. The Amended Credit Agreement, which matures on September 30, 2026, contains customary affirmative, negative and financial covenants as disclosed in Item 7 of our Annual Report on Form 10-K for the fiscal year ended September 30, 2023. As of December 31, 2023, the Company was in compliance with the financial covenants under the Amended Credit Agreement.

At December 31, 2023 and at September 30, 2023, we had no outstanding borrowings under our revolving credit facility. At December 31, 2023, we also had $5,606 in outstanding letters of credit and total availability of $142,489 under our revolving credit facility without triggering the financial covenants under the Amended Credit Agreement.

5. PER SHARE INFORMATION

The following tables reconcile the components of basic and diluted earnings per share for the three months ended December 31, 2023 and 2022:


	Three Months Ended December 31,
	2023		2022
Numerator:
Net income attributable to IES Holdings, Inc.	$	40,956	$	26,402
Increase in noncontrolling interest		(2,782)		(3,055)
Net income attributable to restricted stockholders of IES Holdings, Inc.		—		(11)
Net income attributable to common stockholders of IES Holdings, Inc.	$	38,174	$	23,336

Denominator:
Weighted average common shares outstanding — basic		20,199,587		20,242,114
Effect of dilutive stock options and non-vested securities		235,561		206,921
Weighted average common and common equivalent shares outstanding — diluted		20,435,148		20,449,035

Earnings per share attributable to common stockholders of IES Holdings, Inc.:
Basic	$	1.89	$	1.15
Diluted	$	1.87	$	1.14

For the three months ended December 31, 2023 and 2022, the average price of our common shares exceeded the exercise price of all of our outstanding stock options; therefore, all of our outstanding stock options were included in the computation of diluted earnings per share. For the three months ended December 31, 2023 and 2022, the computation of diluted earnings per share excluded 64,500 and 60,212 unvested Employee PSUs (as defined below), respectively, as the inclusion of such instruments would have been anti-dilutive.

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 Chief Operating Decision Maker (“CODM”) reviews operating results for the purpose of allocating resources and assessing performance. The Company’s

CODM is its Chief Executive Officer.

Transactions between segments, if any, are eliminated in consolidation. Our corporate organization 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 months ended December 31, 2023 and 2022 is as follows:


		Three Months Ended December 31, 2023

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 stock options as well as grants of stock, including restricted stock. Approximately 3.0 million shares of common stock are authorized for issuance under the Equity Incentive Plan, of which approximately 547,804 shares were available for issuance at December 31, 2023.

Stock Repurchase Program

In December 2022, our Board authorized a stock repurchase program for the purchase from time to time of up to $40,000 of the Company’s common stock, replacing the Company's previous repurchase program. 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 219,731 shares of our common stock during the three months ended December 31, 2022 in open market transactions at an average price of

$30.97 per share. We had no repurchases of common stock in open market transactions during the three months ended December 31, 2023.

Treasury Stock

During the three months ended December 31, 2023, we issued 32,180 shares of common stock from treasury stock to employees and repurchased 12,422 shares of common stock from our employees to satisfy statutory tax withholding requirements upon the vesting of certain performance phantom stock units under the Equity Incentive Plan.

During the three months ended December 31, 2022, we issued 71,013 shares of common stock from treasury stock to employees and repurchased 19,142 shares of common stock from our employees to satisfy statutory tax withholding requirements upon the vesting of certain performance phantom stock units under the Equity Incentive Plan. In addition, 187 restricted shares were forfeited and returned to treasury stock.

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.

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.

As of December 31, 2023, the Company had outstanding Employee PSUs, which, subject to the achievement of certain performance metrics, could result in the issuance of 376,533 shares of common stock. During the three months ended December 31, 2023, we granted 85,424 Employee PSUs, 2,535 were forfeited, and 32,180 vested.

A summary of the compensation expense related to our stock awards recognized during the three months ended December 31, 2023 and 2022 is provided in the table below:


	Three Months Ended December 31,

8. 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.

At December 31, 2023, financial assets and liabilities measured at fair value on a recurring basis were limited to our Executive Deferred Compensation 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), debt and equity investments classified as trading securities, and contingent consideration liabilities related to certain of our acquisitions.

Financial assets (liabilities) measured at fair value on a recurring basis as of December 31, 2023 and September 30, 2023, are summarized in the following tables by the type of inputs applicable to the fair value measurements:


	December 31, 2023
			Total Fair Value		Quoted Prices (Level 1)		Significant Unobservable Inputs (Level 3)
Executive savings plan assets		$	851	$	851	$	—

Contingent consideration liability			(4,465)		—		(4,465)
Total		$	(4,339)	$	126	$	(4,465)

In fiscal year 2021, we entered into a contingent consideration arrangement related to the acquisition of Bayonet. The table below presents the change in fair value of this obligation, which used significant unobservable inputs (Level 3). This obligation was settled during the three months ended December 31, 2023, and we did not have any other assets or liabilities measured using significant unobservable inputs at December 31, 2023.

11. 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 December 31, 2023 and September 30, 2023, we had $9,334 and $7,726, 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 or that the timing of payments will not create liquidity issues for the Company.

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 December 31, 2023 and September 30, 2023, $5,606 and $4,166, respectively, of our outstanding letters of credit was utilized to collateralize our insurance program.

Surety

As of December 31, 2023, the estimated cost to complete our bonded projects was approximately $136,569. 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.

12. LEASES

We enter into various contractual arrangements for the right to use facilities, vehicles and equipment. The lease terms generally range from two to ten years for facilities and three to five years for vehicles and equipment. Our lease terms may include the exercise of renewal or termination options when it is reasonably certain these options will be exercised. Our lease agreements do not contain any material residual value guarantees or restrictive covenants.

Current operating and finance lease liabilities of $20,184 and $4,529, respectively, as of December 31, 2023, and 19,496 and 4,301, respectively, as of September 30, 2023, were included in “Accounts payable and accrued expenses” in the Condensed Consolidated Balance Sheets. Non-current finance lease liabilities and finance lease right-of-use assets were included in the “Other non-current liabilities” and “Other non-current assets”, respectively, in the Condensed Consolidated Balance Sheets.

The maturities of our lease liabilities as of December 31, 2023 are as follows:

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, 2023, 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, 2023, 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

Increases in the target federal funds rate throughout calendar years 2022 and 2023 have resulted in higher mortgage rates, which when combined with elevated materials and labor costs, have had a substantial impact on the affordability of housing. While there continue to be several trends, such as rising household formation and population growth in our key markets, that we expect will drive long-term demand for our services in the single-family housing market, decreased housing affordability has led to uncertainty around near-term demand for our services in this market. Within the various other end markets we serve, our customers' capital budgets for new construction projects may be impacted by broader economic, technological or other factors.

The COVID-19 pandemic and its impact on markets, the supply chain and the labor force continue to be areas of focus for our business as we work to protect our workforce and serve our customers. While the pandemic has had less of an impact on our business in the first quarter of fiscal 2024 compared with prior fiscal years, this or any future pandemic or other public health emergency could impact our workforce, customers and suppliers. An inability to procure materials in a timely manner, to complete work on schedule, and to reflect higher materials or labor costs in our pricing to customers has had, and could have in the future, a significant impact on our operating results.

Please refer to Part I. Item 1A. “Risk Factors” of our Annual Report on Form 10-K for the fiscal year ended September 30, 2023 for further information.

Consolidated revenues for the three months ended December 31, 2023, were $59.6 million higher than for the three months ended December 31, 2022, an increase of 10.4%, with increases at our Communications, Infrastructure Solutions and Commercial & Industrial operating segments, slightly offset by 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 December 31, 2023 increased $48.4 million compared to the three months ended December 31, 2022. Our overall gross profit percentage was 22.7% during the three months ended December 31, 2023, as compared to 16.6% during the three months ended December 31, 2022. Gross profit as a percentage of revenue increased at all four of our operating segments. 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 December 31, 2023, our selling, general and administrative expenses were $85.9 million, an increase of $18.1 million, or 26.7%, over the three months ended December 31, 2022, driven largely by increased personnel costs at our Residential operating segment in connection with a reorganization of the segment's management structure in fiscal 2023 and higher incentive compensation at the division level as a result of higher earnings. Selling, general and administrative expenses as a percentage of revenue increased from 11.8% for the three months ended December 31, 2022 to 13.5% for the three months ended December 31, 2023.

Gain on Sale of Assets. Our results for the three months ended December 31, 2022 included a pretax gain on sale of $13.0 million from the sale of STR Mechanical, LLC (“STR”) on October 7, 2022. STR previously operated as part of our Commercial & Industrial segment.

Gain on sale of assets		(4)	—			—	—
Operating income	$	21,378	12.5	%	$	9,441	6.4	%

Revenues. Our Communications segment’s revenues increased by $23.5 million during the three months ended December 31, 2023, or 16.0%, compared to the three months ended December 31, 2022. The increase primarily resulted from an increase in demand from high-tech manufacturing and e-commerce distribution center customers.

Gross Profit. Our Communications segment’s gross profit during the three months ended December 31, 2023 increased by $14.5 million compared to the three months ended December 31, 2022. Gross profit as a percentage of revenue increased from 14.8% to 21.2%. The increase in profitability in the three months ended December 31, 2023 was primarily the result of improved project execution and pricing during the period, as well as the impact of investments we have made in hiring and training personnel to support the growth of our business.

Selling, General and Administrative Expenses. Our Communications segment’s selling, general and administrative expenses increased by $2.6 million, or 21.2%, during the three months ended December 31, 2023, compared to the three months ended December 31, 2022. The increase is primarily a result of higher personnel cost including higher incentive compensation as a result of higher earnings, investment in an organizational structure that will enhance the scalability of our business, and higher wages in an increasingly competitive labor market. Selling, general and administrative expenses as a percentage of revenue in the Communications segment were 8.7% during the three months ended December 31, 2023, compared to 8.4% for the three months ended December 31, 2022.

Gain on sale of assets	(82)		—		(6)		—
Operating income	$	24,100	7.6	%	$	20,505	6.4	%

Revenues. Our Residential segment’s revenues decreased by $2.2 million, or 0.7%, during the three months ended December 31, 2023 compared to the three months ended December 31, 2022. Our multi-family revenue decreased as we have become more selective in our bidding process, and have reduced our activity in certain areas where we experienced project execution challenges in the prior year, resulting in a $5.1 million decrease in revenues compared to the prior year period. This was partially offset by expansion into new markets and continued strong demand in our single-family business, where revenues increased by $2.9 million compared to the prior year period.

Gross Profit. During the three months ended December 31, 2023, our Residential segment's gross profit increased by $15.8 million, or 26.5%, compared to the three months ended December 31, 2022. Gross profit as a percentage of revenue increased to 23.9% during the three months ended December 31, 2023, from 18.7% for the three months ended December 31, 2022. The increase in profitability was driven primarily by improved project execution in our multi-family business, as well as the benefit of improved procurement and other processes implemented as part of the reorganization of the segment in fiscal 2023.

Selling, General and Administrative Expenses. Our Residential segment's selling, general and administrative expenses increased by $12.3 million, or 31.6%, during the three months ended December 31, 2023, compared to the three months ended December 31, 2022. The increase was driven by higher personnel costs in connection with a reorganization of the segment's management structure in fiscal 2023 and incentive profit sharing for division management. Selling, general and administrative expenses as a percentage of revenue in the Residential segment increased to 16.3% during the three months ended December 31, 2023, compared to 12.3% in the three months ended December 31, 2022.

Gain on sale of assets		—	—			(19)	—
Operating income	$	10,906	17.3	%	$	4,725	9.6	%

Revenues. Revenues in our Infrastructure Solutions segment increased $13.6 million during the three months ended December 31, 2023, an increase of 27.6% compared to the three months ended December 31, 2022, driven primarily by continued strong demand in our custom power solutions manufacturing businesses.

Gross Profit. Our Infrastructure Solutions segment’s gross profit during the three months ended December 31, 2023 increased $7.7 million as compared to the three months ended December 31, 2022, primarily resulting from operational improvements within our manufacturing facilities during the quarter, as well as improved pricing. Gross profit as a percentage of revenue increased from 21.2% to 28.9%.

Selling, General and Administrative Expenses. Our Infrastructure Solutions segment’s selling, general and administrative expenses during the three months ended December 31, 2023 increased $1.5 million when compared to the three months ended December 31, 2022, primarily as a result of increased employee compensation cost. Selling, general and administrative expenses as a percentage of revenue was 11.6% at December 31, 2023 compared to 11.7% at December 31, 2022.

Commercial & Industrial


	Three Months Ended December 31,
	2023				2022
	$		%		$		%

Gain on sale of assets		15	—			(13,035)	(21.6)
Operating income	$	7,045	8.3	%	$	10,960	18.2	%

Revenues. Revenues in our Commercial & Industrial segment increased $24.7 million, or 41.0%, during the three months ended December 31, 2023, compared to the three months ended December 31, 2022. The increase primarily relates to a large data center project.

Gross Profit. Our Commercial & Industrial segment’s gross profit during the three months ended December 31, 2023, increased by $10.3 million, as compared to the three months ended December 31, 2022. Gross profit as a percentage of revenue increased from 6.0% for the quarter ended December 31, 2022 to 16.4% for the quarter ended December 31, 2023. Our results for the quarter ended December 31, 2022 were impacted by continuing operating challenges at one branch that incurred significant losses during fiscal 2022 and into fiscal 2023. In the three months ended December 31, 2023, segment results benefited from improved project execution, improving bid margins in certain markets, and a more selective bidding strategy implemented in the prior year.

Selling, General and Administrative Expenses. Our Commercial & Industrial segment’s selling, general and administrative expenses during the three months ended December 31, 2023 increased $1.2 million, or 20.4%, compared to the three months ended December 31, 2022. Selling, general and administrative expenses as a percentage of revenue decreased from 9.4% to 8.1% for the three months ended December 31, 2023 compared to the three months ended December 31, 2022 as we benefited from the scale of our operations.

Gain on Sale of Assets. As discussed above, our results for the three months ended December 31, 2022 included a pretax gain on sale of $13.0 million from the sale of STR in October 2022.

During the three months ended December 31, 2023, we incurred interest expense of $0.4 million 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 $142.4 million. This compares to interest expense of $1.2 million for the three months ended December 31, 2022, primarily comprising interest expense from our revolving credit facility, which had an average outstanding balance of $43.0 million, in addition to fees on an average letter of credit balance of $5.4 million under our revolving credit facility and an average unused line of credit balance of $80.7 million. The reduction in interest expense in the three months ended December 31, 2023 compared to the three months ended December 31, 2022 was a result of a decrease in average outstanding borrowings under our revolving credit facility, which had no outstanding balance during the three months ended December 31, 2023.

The improvement in Total other (income) expense, net for the three months ended December 31, 2023 as compared with December 31, 2022 is primarily the result of interest income earned during the three months ended December 31, 2023 on short-term investments made in late fiscal 2023 with no such interest income in the three months ended December 31, 2022, and unrealized gains on investments in trading securities of $0.1 million in the three months ended December 31, 2023, compared to no interest income and unrealized losses of $0.8 million in the three months ended December 31, 2022.

PROVISION FOR INCOME TAXES

We recorded income tax expense of $15.4 million for the three months ended December 31, 2023, compared to $10.0 million for the three months ended December 31, 2022, driven 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, 2023. Some of the more significant estimates include revenue recognition, business combinations, valuation allowance for deferred tax assets 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, 2023.

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 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):


	December 31,		September 30,		June 30,		March 31,
	2023		2023		2023		2023
Remaining performance obligations	$	1,072,593	$	1,143,423	$	1,071,605	$	1,012,111

Backlog	$	1,452,056	$	1,558,012	$	1,529,662	$	1,389,059
(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 three months ended December 31, 2023, working capital exclusive of cash increased by $23.3 million from September 30, 2023, reflecting a $44.6 million increase in current assets excluding cash partially offset by a $21.3 million increase in current liabilities during the period.

During the three months ended December 31, 2023, our current assets exclusive of cash increased to $640.1 million, as compared to $595.5 million as of September 30, 2023. An increase in activity at our Communications, Infrastructure Solutions and Commercial & Industrial businesses drove a $24.7 million increase in trade accounts receivable. While the rate of collections may vary, our typically secured position, resulting from our ability in general to secure liens against our customers’ overdue receivables, offers some protection that collection will occur eventually to the extent that our security retains value. We also had an $18.1 million increase in inventories from advance material purchases primarily for projects not yet commenced in our Residential multi-family business.

During the three months ended December 31, 2023, our total current liabilities increased by $21.3 million to $421.9 million, compared to $400.6 million as of September 30, 2023, driven by a $23.2 million increase in billings in excess of costs and estimated earnings driven by the timing of contract billings on projects on which revenue is recognized using the percentage of completion method, partially offset by a $1.9 million decrease in accounts payable and accrued expenses primarily as a result of the timing of payments by our Communications segment.

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 December 31, 2023, the estimated cost to complete our bonded projects was approximately $136.6 million.

LIQUIDITY AND CAPITAL RESOURCES

The Revolving Credit Facility

We are a party to the Third Amended and Restated Credit and Security Agreement (the "Amended Credit Agreement"), which provides for a maximum borrowing amount of $150 million. The Amended Credit Agreement contains customary affirmative, negative and financial covenants and events of default.

Borrowings under the Amended Credit Agreement may not exceed a Borrowing Base, as defined in the Amended Credit Agreement, that is determined monthly based on available collateral, primarily certain accounts receivables, inventories, and equipment. Amounts outstanding bear interest at a per annum rate equal to the Daily Three Month Secured Overnight Financing Rate ("SOFR"), plus an interest rate margin, which is determined quarterly, based on the following thresholds:

Level

Thresholds

Interest Rate Margin

If Liquidity is less than 35% of the Maximum Revolver Amount (each as defined in the Amended Credit Agreement) at any time during the period

2.00 percentage points

If Liquidity is greater than or equal to 35% of the Maximum Revolver Amount at all times during the period and less than 50% of the Maximum Revolver Amount at any time during the period

1.75 percentage points

III

If Liquidity is greater than or equal to 50% of the Maximum Revolver Amount at all times during the period

1.50 percentage points

In addition, we are charged monthly in arrears for (1) an unused commitment fee of 0.25% per annum, (2) a collateral monitoring fee of $5 thousand per quarter, (3) a letter of credit fee based on the then-applicable interest rate margin (4) appraisal fees, costs and expenses and (5) certain other fees and charges as specified in the Amended Credit Agreement.

As of December 31, 2023, we were in compliance with the financial covenants under the Amended Credit Agreement, requiring that we maintain:

•a Fixed Charge Coverage Ratio (as defined in the Amended Credit Agreement), measured quarterly on a trailing four-quarter basis at the end of each quarter, of at least 1.1 to 1.0; and

•minimum Liquidity of at least 10% of the Maximum Revolver Amount, or $15.0 million; with, for purposes of this covenant, at least 50% of our Liquidity comprised of Excess Availability (as defined in the Amended Credit Agreement).

At December 31, 2023, our Liquidity was $229.9 million, our Excess Availability was $142.5 million (or greater than 50% of minimum Liquidity), and our Fixed Charge Coverage Ratio was 9.8:1.0.

If in the future our Liquidity falls below $15.0 million (or Excess Availability falls below 50% of our minimum Liquidity), our Fixed Charge Coverage Ratio is less than 1.1:1.0, 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 December 31, 2023, we had $5.6 million in outstanding letters of credit and no 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, elevated commodity prices, and the steps taken to mitigate the impact of supply chain disruptions.

Net cash provided by operating activities was $25.0 million during the three months ended December 31, 2023, as compared to $14.3 million in the three months ended December 31, 2022. The increase in operating cash flow resulted from increased earnings, partially offset by an increase in cash used in working capital during the three months ended December 31, 2023 as compared with the three months ended December 31, 2022.

Investing Activities

Net cash used in investing activities was $6.0 million for the three months ended December 31, 2023, compared to $16.3 million provided by investing activities in the three months ended December 31, 2022. During the three months ended December 31, 2023, we used $6.5 million for capital expenditures to support the growth of our business. During the three months ended December 31, 2022, the sale of assets, including the sale of STR, provided cash of $19.2 million, which was partially offset by $2.7 million used for capital expenditures.

Financing Activities

Net cash used in financing activities for the three months ended December 31, 2023 was $7.3 million, compared to $50.3 million for the three months ended December 31, 2022. Net cash used in financing activities for the three months ended December 31, 2023 included $4.1 million to settle our contingent consideration liability related to prior year acquisitions and $1.3 million in distributions to noncontrolling interests under operating agreements in connection with certain acquisitions. Net cash used in financing activities for the three months ended December 31, 2022 included net repayments on our credit facility of $39.7 million, $7.5 million used to repurchase our common stock, including repurchases to satisfy statutory withholding requirements upon the vesting of employee stock compensation, and distributions of $2.3 million to noncontrolling interests under operating agreements in connection with certain acquisitions.

Stock Repurchase Program

In December 2022, our Board authorized a stock repurchase program for the purchase from time to time of up to $40.0 million of the Company’s common stock, replacing the Company's previous repurchase program. 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 had no purchases pursuant to our repurchase programs during the three months ended December 31, 2023.

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 December 31, 2023, we did not have any such firm commitments to purchase materials outstanding. 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, 2023. We expect that cash and cash equivalents, cash flow from operations and availability under our revolving 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 our outstanding borrowings under 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, 2023.

Commodity Risk

Our exposure to significant market risks includes fluctuations in commodity prices for copper, aluminum, steel, electronic 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.

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. The Amended Credit Agreement uses SOFR as the benchmark for establishing the interest rate charged on our borrowings. If 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. We had no borrowings outstanding under our revolving credit facility as of December 31, 2023.

Item 4. Controls and Procedures

Changes in Internal Control Over Financial Reporting

There have not been any 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.

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 December 31, 2023, to provide reasonable assurance that information required to be disclosed in our reports filed or submitted under the Exchange Act is 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.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

Item 5. Other Information

Rule 10b5-1 Trading Arrangements

From time to time, members of the Company's Board of Directors and officers of the Company may enter into Rule 10b5-1 trading plans, which allow for the purchase or sale of common stock under pre-established terms at times when directors and officers might otherwise be prevented from trading under insider trading laws or because of self-imposed blackout periods. Such trading plans are intended to satisfy the affirmative defense conditions of Rule 10b5-1(c) under the Exchange Act and comply with the Company's Insider Trading Policy. During the three months ended December 31, 2023, none of the Company's directors or officers adopted, modified or terminated a “Rule 10b5-1 trading arrangement” or a “non-Rule 10b5-1 trading arrangement” as each term is defined under Item 408 of Regulation S-K.

Accounting Policies [Abstract]
Business Description and Basis of Presentation [Text Block]	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, 2023. 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. Noncontrolling Interest In connection with our acquisitions of Edmonson Electric, LLC 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. 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. The purchase price is variable, based on a multiple of earnings as defined in the operating agreements. Therefore, this noncontrolling interest is carried at the greater of the balance determined under Accounting Standards Codification (“ASC”) 810 and the redemption amounts assuming the noncontrolling interests were redeemable at the balance sheet date. If all of the noncontrolling interests remaining outstanding at December 31, 2023 had been redeemable at that date, the redemption amount would have been $54,969. 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 Update and Change in Accounting Principle	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 will impact how we account for future business combinations.

Risks and Uncertainties [Abstract]
Controlling Shareholder [Text Block]	2. CONTROLLING STOCKHOLDER Tontine Associates, L.L.C. (“Tontine Associates”), together with its affiliates (collectively, “Tontine”), is the Company’s controlling stockholder, owning approximately 57 percent of the Company’s outstanding common stock based on a Form 4 filed by Tontine with the SEC on January 24, 2024 and the Company's shares outstanding as of January 31, 2024. 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 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. 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. In December 2022, the Company entered into an amendment of the sublease agreement, which was set to terminate on February 28, 2023, to extend the term of the agreement through August 31, 2024 and to increase the monthly payments from approximately $8 to approximately $9 effective March 1, 2023. 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 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.

Commitments and Contingencies	Dec. 31, 2023
Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies Disclosure [Text Block]	11. 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 December 31, 2023 and September 30, 2023, we had $9,334 and $7,726, 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 or that the timing of payments will not create liquidity issues for the Company. 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 December 31, 2023 and September 30, 2023, $5,606 and $4,166, respectively, of our outstanding letters of credit was utilized to collateralize our insurance program. Surety As of December 31, 2023, the estimated cost to complete our bonded projects was approximately $136,569. 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 December 31, 2023, we did not have any such firm commitments to purchase materials outstanding.

Use of Estimates, Policy	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 Update and Change in Accounting Principle	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 will impact how we account for future business combinations.
