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:
•the impact of the COVID-19 outbreak or future epidemics on our business, including the potential for new or continuing job site closures or work stoppages, supply chain disruptions, delays in awarding new project bids, construction delays, reduced demand for our services, delays in our ability to collect from our customers, or illness of management or other employees;
•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 and certain plastics;
•potential supply chain disruptions due to credit or liquidity problems faced by our suppliers;
•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;
•a general reduction in the demand for our services;
•backlog that may not be realized or may not result in profits;
•closures or sales of facilities resulting in significant future charges, including potential warranty losses or other unexpected liabilities, or a significant disruption of our operations;
•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;
3

•interruptions to our information systems and cyber security or data breaches;
•liabilities under laws and regulations protecting the environment;
•loss of key personnel and effective transition of new management, or inability to transfer, renew and obtain electrical and other professional licenses;
•the possibility that certain tax benefits of our net operating losses may be restricted or reduced in a change in ownership or a change 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, complete acquisitions, and for debt service;
•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;
•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 we may incur under such revolving credit facility;
•inaccurate estimates used when entering into fixed-priced 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;
•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 phase-out, replacement or unavailability of the London Interbank Offered Rate ("LIBOR");
•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, as a result of which it could be 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 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.
4

You should understand that the foregoing, as well as other risk factors discussed in this document and those listed in Part I, Item 1A of our Annual Report on Form 10-K for the fiscal year ended September 30, 2020 and Part II, Item 1A of our Quarterly Report on Form 10-Q for the fiscal quarter ended March 31, 2021, 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 without limitation information concerning our controlling stockholder, 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.

(Unaudited)
1. BUSINESS AND ACCOUNTING POLICIES
Description of the Business
IES Holdings, Inc. is a holding company that owns and manages operating subsidiaries that design and install integrated electrical and technology systems and provide infrastructure products and services across a variety of end-markets, including data centers, residential housing and commercial and industrial facilities. Our operations are organized into the following four principal 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.
•Infrastructure Solutions – Provider of electro-mechanical solutions for industrial operations, including apparatus repair and custom-engineered products, such as generator enclosures, to be 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, 2020. 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, NEXT Electric, LLC in fiscal 2017, and STR Mechanical, LLC in fiscal 2016, 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
11

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. During the quarter ended June 30, 2021, we acquired the noncontrolling interest in STR Mechanical, LLC for $1,188. If all of the noncontrolling interests remaining outstanding at June 30, 2021 had been redeemable at that date, the redemption amount would have been $17,355. During the three and nine months ended June 30, 2021, we recorded valuation adjustments to the balance sheet carrying value of noncontrolling interest of a $103 decrease and $400 increase, respectively.
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 and analyzing goodwill, investments, intangible assets and long-lived asset impairments and adjustments, allowance for credit losses, stock-based compensation, reserves for legal matters, realizability of deferred tax assets, unrecognized tax benefits and self-insured claims liabilities and related reserves.
Accounting Standards Recently Adopted
In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update No. 2016-13, Financial Instruments – Credit Losses (“ASU 2016-13”), which requires companies to consider historical experiences, current market conditions and reasonable and supportable forecasts in the measurement of expected credit losses, with further clarifications made in April 2019 and May 2019 with the issuances of Accounting Standard Updates No. 2019-04 and 2019-05. This update is effective for fiscal years beginning after December 15, 2019 and for interim periods within those fiscal years. We adopted this standard on October 1, 2020, using a modified retrospective transition method through a cumulative-effect adjustment to beginning retained earnings in the period of adoption. As a result, we recorded an increase in the Allowance for Credit Losses of $284, an increase to Deferred Tax Assets of $70, and an increase of $214 to retained earnings.
ASU 2016-13 requires the recognition of expected credit losses on financial assets measured at amortized cost basis. In calculating our expected credit losses, we considered trade receivables, retainage, and costs and estimated earnings in excess of billings, all of which constitute a homogenous portfolio, and therefore, to measure the expected credit loss, they have been grouped together.
We have elected to calculate an expected credit loss based on loss rates from historical data. Each segment groups financial assets with similar risk characteristics and collectively assesses the expected credit losses. If an individual asset experiences credit deterioration to the extent the credit risk is no longer characteristic of the other assets in the group, it will be analyzed individually. The loss rates for our portfolios include our history of credit loss expense, the aging of our receivables, our expectation of payments and adjustment for forward-looking factors specific to the macroeconomic trends in the U.S. construction market.
Other than trade receivables due in one year or less, we do not have any other financial assets that are past due or are on non-accrual status.
In August 2018, the FASB issued Accounting Standard Update No. 2018-13, Fair Value Measurement Disclosure Framework (“ASU 2018-13”), to modify certain disclosure requirements for fair value measurements. Under the new guidance, registrants will need to disclose weighted average information for significant unobservable inputs for all Level 3 fair value measurements. The guidance does not specify how entities should calculate the weighted average, but requires them to explain their calculation. The new guidance also requires disclosing the changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements of instruments held at the end of the reporting period. This guidance is effective for fiscal years beginning after December 15, 2019 and for interim periods within those fiscal years. We adopted this standard on October 1, 2020, with no impact on our Condensed Consolidated Financial Statements.
Accounting Standards Not Yet Adopted
In December 2019, the FASB issued Accounting Standard Update No. 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes.” This standard simplifies the accounting for income taxes by eliminating certain exceptions to the guidance in Topic 740 related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. The standard also simplifies aspects of the accounting for franchise taxes and enacted changes in tax laws or rates and clarifies the accounting for transactions that result in a step-up in the tax basis of goodwill. This update is effective for fiscal years beginning after December 15, 2020 and for interim periods within that year. Early adoption is permitted. We expect to adopt this standard on October 1, 2021, and do not expect it to have a material impact on our Condensed Consolidated Financial Statements.

2. CONTROLLING STOCKHOLDER
Tontine Associates, L.L.C. ("Tontine Associates"), together with its affiliates (collectively, “Tontine”), is the Company’s controlling stockholder, owning approximately 56 percent of the Company’s outstanding common stock according to a Form 4 filed by Tontine with the SEC on June 9, 2021. 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 ownership of IES could occur. A change in ownership, as defined by Internal Revenue Code Section 382, could reduce the availability of the Company’s net operating losses (“NOLs”) for federal and state income tax purposes. Furthermore, 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. The Company previously had in place a tax benefit protection plan (the “NOL Rights Plan”), designed to deter an acquisition of the Company's stock in excess of a threshold amount that could trigger a change in ownership within the meaning of Internal Revenue Code Section 382. However, on May 7, 2021, we amended the NOL Rights Plan, accelerating the expiration of the plan from December 31, 2021 to May 21, 2021. As a result of this amendment, the NOL Rights Plan has now expired.
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 Company's Board of Directors (the "Board"), 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 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 December 31, 2017.
The Company is party to a sublease agreement with Tontine Associates for corporate office space in Greenwich, Connecticut. The sublease extends through February 27, 2023, with monthly payments due in the amount of approximately $8. 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.
13

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 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 segment, 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 we have the right to bill the customer as costs are incurred. Such assessment involves an evaluation of contractual termination clauses. Where 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 fixed price arrangements, 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 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.
Costs of Obtaining a Contract
In certain of our operations, we incur commission costs related to entering into a contract that we only incurred because of that contract. When this occurs, we capitalize that cost and amortize it over the expected term of the contract. At June 30, 2021, we had capitalized commission costs of $100.
We generally do not incur significant incremental costs related to obtaining or fulfilling a contract prior to the start of a project. When significant pre-contract costs are incurred, they will be capitalized and amortized on a percentage of completion basis over the life of the contract.
Disaggregation of Revenue
We disaggregate our revenue from contracts with customers by activity and contract type, as these categories reflect how the nature, amount, timing and uncertainty of our revenue and cash flows are affected by economic factors. Our consolidated revenue for the three and nine months ended June 30, 2021 and 2020 was derived from the following activities. See details in the following tables:

Accounts Receivable
Accounts receivable include amounts which we have billed or have an unconditional right to bill our customers. As of June 30, 2021, Accounts receivable included $18,525 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 June 30, 2021 and 2020, we recognized revenue of $25,851 and $19,661 related to our contract liabilities at April 1, 2021 and 2020, respectively. During the nine months ended June 30, 2021 and 2020, we recognized revenue of $41,121 and $29,692 related to our contract liabilities at October 1, 2020 and 2019, respectively.
We did not have any impairment losses recognized on our receivables or contract assets for the three and nine months ended June 30, 2021 or 2020.
Remaining Performance Obligations
Remaining performance obligations represent the unrecognized revenue value of our contract commitments. New awards represent the total expected revenue value of new contract commitments undertaken during a given period, as well as additions to the scope of existing contract commitments. Our new performance obligations vary significantly each reporting period based on the timing of our major new contract commitments. At June 30, 2021, we had remaining performance obligations of $668,716. The Company expects to recognize revenue on approximately $555,454 of the remaining performance obligations over the next 12 months, with the remaining recognized thereafter.
For the three and nine months ended June 30, 2021, net revenue recognized from our performance obligations satisfied in previous periods was not material.
4. DEBT
At June 30, 2021 and September 30, 2020, we had $30,479 and $12, respectively, in borrowings outstanding under our revolving credit facility with Wells Fargo Bank, N.A. ("Wells Fargo"), and long-term debt related to loans on capital expenditures of $97 and $205, respectively. At June 30, 2021, we also had $4,527 in outstanding letters of credit and total availability of $64,331 under our revolving credit facility without triggering our financial covenants under the Amended Credit Agreement (as defined below).
The Company maintains a $100 million revolving credit facility that matures on September 30, 2024, pursuant to our Second Amended and Restated Credit and Security Agreement with Wells Fargo (as amended, the “Amended Credit Agreement”). The Amended Credit Agreement contains customary affirmative, negative and financial covenants as disclosed in Item 7 of our Annual Report on Form 10-K for the year ended September 30, 2020. As of June 30, 2021, the Company was in compliance with the financial covenants under the Amended Credit Agreement.

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 office provides general and administrative services, as well as support services, to each of our four operating segments. Management allocates certain shared costs between segments for selling, general and administrative expenses and depreciation expense.
Segment information for the three and nine months ended June 30, 2021 and 2020 is as follows:

7. STOCKHOLDERS’ EQUITY
Equity Incentive Plan
The Company’s 2006 Equity Incentive Plan, as amended and restated (the “Equity Incentive Plan”), provides for grants of 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 842,141 shares were available for issuance at June 30, 2021.
Stock Repurchase Program
In 2015, our Board authorized a stock repurchase program for the purchase from time to time of up to 1.5 million shares of the Company’s common stock, and on May 2, 2019, our Board authorized the repurchase from time to time of up to an additional 1.0 million shares of our common stock under the stock 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 or reinstated at any time at the Company’s discretion and without notice. We repurchased no shares of our common stock during the three and nine months ended June 30, 2021. We repurchased 26,711 and 224,959 shares, respectively, of our common stock during the three and nine months ended June 30, 2020 in open market transactions at an average price of $20.29 and $22.32 per share, respectively.
Treasury Stock
During the nine months ended June 30, 2021, we issued 71,420 shares of common stock from treasury stock to employees and repurchased 32,323 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, 13,996 restricted shares were forfeited by
19

certain former employees upon their departure and returned to treasury stock. We also issued 380 unrestricted shares of common stock from treasury stock to members of our Board of Directors as part of their overall compensation, and we issued 68,860 shares from treasury stock to satisfy the vesting of Director PSUs (as defined below) in conjunction with the departure of a Board member.
During the nine months ended June 30, 2020, we issued 113,408 shares of common stock from treasury stock to employees and repurchased 17,427 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. We also issued 5,225 unrestricted shares of common stock from treasury to members of our Board of Directors as part of their overall compensation and 5,750 unrestricted shares of common stock from treasury stock to satisfy the exercise of outstanding options. In addition, we repurchased 224,959 shares of common stock on the open market pursuant to our stock repurchase program.
Restricted Stock
We granted no restricted shares to executives during the nine months ended June 30, 2021. Of the awards previously granted, 8,183 shares vested and 13,996 shares were forfeited by certain former employees upon their departure. The remaining restricted shares either vest subject to the achievement of specified levels of cumulative net income before taxes or vest based on the passage of time. During the three months ended June 30, 2021 and 2020, we recognized $36 and $521, respectively, in compensation expense related to all restricted stock awards. During the nine months ended June 30, 2021 and 2020, we recognized $109 and $1,316, respectively, in compensation expense related to all restricted stock awards. At June 30, 2021, the unamortized compensation cost related to outstanding unvested restricted stock was $202.
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. During the three months ended June 30, 2021 and 2020, we recognized $93 and $97, respectively, in compensation expense related to these grants. During the nine months ended June 30, 2021 and 2020, we recognized $280 and $293, respectively, in compensation expense related to these grants.
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 June 30, 2021, the Company had outstanding Employee PSUs, which, subject to the achievement of certain performance metrics, could result in the issuance of 258,253 shares of common stock. Of the Employee PSUs granted, 114,067 Employee PSUs have been forfeited, and 121,102 have vested. During the three months ended June 30, 2021 and 2020, we recognized $928 and $505, respectively, in compensation expense related to Employee PSU grants. During the nine months ended June 30, 2021 and 2020, we recognized $2,336 and $1,121, respectively, in compensation expense related to Employee PSU grants. In July 2021, we issued an additional 22,807 Employee PSUs.

8. EMPLOYEE BENEFIT PLANS
401(k) Plan
In November 1998, we established the IES Holdings, Inc. 401(k) Retirement Savings Plan. All full-time IES employees are eligible to participate on the first day of the month subsequent to completing sixty days of service and attaining age twenty one. Participants become vested in our matching contributions following three years of service. We also maintain several subsidiary retirement savings plans. During the three months ended June 30, 2021 and 2020, we recognized $847 and $665, respectively, in matching expense. During the nine months ended June 30, 2021 and 2020, we recognized $2,326 and $1,747, respectively, in matching expense.
Post Retirement Benefit Plans
Certain individuals at one of the Company’s locations are entitled to receive fixed annual payments pursuant to post retirement benefit plans. We had an unfunded benefit liability of $585 and $719 recorded as of June 30, 2021 and September 30, 2020, respectively, related to such plans.
9. FAIR VALUE MEASUREMENTS
Fair Value Measurement Accounting
Fair value is considered the price to sell an asset, or transfer a liability, between market participants on the measurement date. Fair value measurements assume that (1) the asset or liability is exchanged in an orderly manner, (2) the exchange is in the principal market for that asset or liability, and (3) the market participants are independent, knowledgeable, and able and willing to transact an exchange. Fair value accounting and reporting establishes a framework for measuring fair value by creating a hierarchy for observable independent market inputs and unobservable market assumptions and expands disclosures about fair value measurements. Considerable 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 June 30, 2021, 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), and contingent consideration liabilities related to certain of our acquisitions.
Financial assets and liabilities measured at fair value on a recurring basis as of June 30, 2021 and September 30, 2020, are summarized in the following tables by the type of inputs applicable to the fair value measurements:

| June 30, 2021

We entered into a contingent consideration arrangement related to the acquisition of Bayonet. At June 30, 2021, we estimated the fair value of this contingent consideration liability at $4,147. The table below presents the fair value of this obligation, which used significant unobservable inputs (Level 3).

12. COMMITMENTS AND CONTINGENCIES
Legal Matters
From time to time we are a party to various claims, lawsuits and other legal proceedings that arise in the ordinary course of business. We maintain various insurance coverages to minimize financial risk associated with these proceedings. None of these proceedings, separately or in the aggregate, are expected to have a material adverse effect on our financial position, results of operations or cash flows. With respect to all such proceedings, we record reserves when it is probable that a liability has been incurred and the amount of loss can be reasonably estimated. We expense routine legal costs related to these proceedings as they are incurred. As of June 30, 2021, we did not have any material pending legal proceedings.
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 insureds under our insurance policies. Losses are accrued based upon our known claims incurred and an estimate of claims incurred but not reported. As a result, many of our claims are effectively self-insured. Many claims against our insurance are in the form of litigation. At June 30, 2021 and September 30, 2020, we had $5,642 and $6,254, 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 June 30, 2021 and September 30, 2020, $4,327 and $5,464, respectively, of our outstanding letters of credit were utilized to collateralize our insurance program.
Surety
As of June 30, 2021, the estimated cost to complete our bonded projects was approximately $98,342. 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. At each of June 30, 2021 and September 30, 2020, $200 of our outstanding letters of credit were to collateralize our vendors. Posting letters of credit in favor of our insurers, customers or vendors reduces the borrowing availability under our revolving credit facility.
From time to time we may enter into firm purchase commitments for materials, such as copper or aluminum wire, which we expect to use in the ordinary course of business. These commitments are typically for terms of less than one year and require us to buy minimum quantities of materials at specific intervals at a fixed price over the term. As of June 30, 2021, we had commitments of $13,771 outstanding under agreements to purchase copper wire over the next four months in the ordinary course of business.
13. LEASES
We enter into various contractual arrangements for the right to use facilities, vehicles and equipment. The lease term generally ranges from two to ten years for facilities and three to five years for vehicles and equipment. Our lease terms may reflect 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 liabilities of $13,668 and $832, respectively, as of June 30, 2021, and $11,056 and $418, respectively, as of September 30, 2020, 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.

14. BUSINESS COMBINATIONS AND DIVESTITURES
Fiscal 2021
The Company completed the following four acquisitions during the nine months ended June 30, 2021:
•Edmonson Electric, LLC ("Edmonson") - On May 18, 2021, we acquired an 80% ownership interest in Edmonson, a Land O'Lakes, Florida-based provider of residential electric, low voltage, and heating, ventilation and air conditioning (HVAC)
24

installation services. The acquisition of Edmonson expands our presence in the Florida market and adds electrical to our Florida service offerings. Edmonson is part of our Residential segment and continues to operate under the Edmonson name.
•Bayonet Plumbing, Heating & Air-Conditioning, LLC ("Bayonet") - On December 21, 2020, we acquired an 80% ownership interest in Bayonet, a Hudson, Florida-based provider of residential HVAC and plumbing installation and maintenance services. The acquisition of Bayonet allows us to expand into the Florida market, while adding plumbing and HVAC to our service offerings. Bayonet is part of our Residential segment and continues to operate under the Bayonet name.
•Wedlake Fabricating, Inc. (“Wedlake”) - On November 19, 2020, we acquired Wedlake, a Tulsa, Oklahoma-based manufacturer of custom generator enclosures that are primarily used by data centers and large commercial and industrial facilities. The acquisition of Wedlake expands our generator enclosures business and our geographic footprint. Wedlake is part of our Infrastructure Solutions segment and continues to operate under the Wedlake name.
•K.E.P. Electric, Inc. (“KEP”) - On November 5, 2020, we acquired KEP, a Batavia, Ohio-based electrical contractor specializing in the design and installation of electrical systems for single-family housing and multi-family developments. The acquisition of KEP, which has operations in Ohio and Kentucky, advances the expansion of our Residential service offerings into the Midwest. KEP is part of our Residential segment and continues to operate under the KEP name.
Total aggregate cash consideration for these acquisitions was $92,694, of which $10,916 was paid into escrow pending discharge of the acquired companies' indebtedness under the Paycheck Protection Program ("PPP") established by the Coronavirus Aid, Relief, and Economic Security Act and implemented by the U.S. Small Business Administration. Loans made under the PPP are eligible to be forgiven if certain criteria are met. As of June 30, 2021, all PPP loans were forgiven and escrow payments have been distributed to the respective sellers.
In addition to the cash consideration, the purchase price also includes contingent consideration with respect to the acquisition of Bayonet of up to $4,500 due in December 2023. Amounts to be paid are contingent on earnings achieved over a three year period, and will accrue interest on the $4,500 at a rate of 3%, to be paid quarterly. This contingent liability was valued at $4,074 as of the date of the acquisition.
The Company accounted for the transactions under the acquisition method of accounting, which requires recording assets and liabilities at fair value (Level 3). The valuations derived from the estimated fair value assessments and assumptions used by management are preliminary pending finalization of certain tangible and intangible asset valuations and assessment of deferred taxes. While management believes the preliminary estimates and assumptions underlying the valuations are reasonable, different estimates and assumptions could result in different values being assigned to individual assets acquired and liabilities assumed. This may result in further adjustments to the preliminary amounts recorded. The preliminary valuation of the assets acquired and liabilities assumed is as follows:

Current assets | $ | 36,256 |
Property and equipment |  | 11,965 |
Intangible assets |  | 59,695 |
Goodwill |  | 38,264 |
Operating right of use assets |  | 802 |
Current liabilities |  | (29,212) |
Operating long-term lease liability |  | (342) |
Deferred tax liability |  | (3,168) |
Noncontrolling interest |  | (21,566) |
Net assets acquired | $ | 92,694 |

With regard to goodwill, the balance is attributable to the workforce of the acquired businesses and other intangibles that do not qualify for separate recognition. In connection with these acquisitions, the preliminary estimate of acquired goodwill is $38,264 of which $24,611 is estimated to be tax deductible.
The intangible assets acquired primarily consisted of Customer Relationships and Trade Names with a total weighted-average amortization period of 6.4 years.
These acquisitions contributed $53,881 in revenue and $665 in operating income during the three months ended June 30, 2021. These acquisitions contributed $98,420 in revenue and $3,101 in operating income during the nine months ended June 30, 2021.

Fiscal 2020
We completed two acquisitions in fiscal 2020 for total aggregate cash consideration of $28,952. We acquired both Aerial Lighting & Electric, Inc. ("Aerial") and Plant Power and Control Systems, L.L.C. ("PPCS") in February 2020.

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 year ended September 30, 2020, 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 year ended September 30, 2020, for a discussion of the Company’s services and corporate strategy. IES Holdings, Inc., a Delaware corporation, is a holding company that owns and manages operating subsidiaries that design and install integrated electrical and technology systems and provide infrastructure products and services across a variety of end markets, including data centers, residential housing, and commercial and industrial facilities. Our operations are currently organized into four principal business segments: Communications, Residential, Infrastructure Solutions and Commercial & Industrial.
Impact of COVID-19 and Current Market Conditions on Our Business
The coronavirus disease 2019 (“COVID-19”) pandemic and its ongoing impact on markets and the supply chain continue to influence trends affecting our business. We are beginning to see indicators that some of our customers who delayed projects or reduced operations during the pandemic are resuming normal levels of activity. However, we continue to experience increased prices or limited availability for certain materials necessary for our projects, notably copper, steel, electrical components, and certain plastics.
The COVID-19 pandemic and related responses are continuing to evolve, and therefore, continue to present potential new risks to our business, particularly in light of new variants of the virus. To date, the COVID-19 pandemic has had a number of adverse impacts on our results of operations. While government restrictions and customer reductions in business activity have eased in most areas, we continue to monitor and implement evolving health and safety protocols. Factors that we expect will continue to affect our results of operations in the future include, but are not limited to, the potential impacts on our workforce of either illness or the shut-down of job sites; a reduced demand for our services; increases in operating costs due to disruptions and personal protective equipment requirements and other increased employment-related costs; potential supply chain disruptions; increased material prices; and limitations on the ability of our customers to pay us on a timely basis. We may also be more vulnerable to security breaches, cyber-attacks, computer viruses, ransomware, or other similar events, particularly with respect to employees working remotely.
We are continuing to monitor conditions affecting our business and will take actions as may be necessary to protect the health and safety of our employees and to serve our customers. The ultimate impact and the extent to which the COVID-19 pandemic will continue to affect our business, results of operations and financial condition are difficult to predict and depend on numerous evolving factors outside our control including: emergence of new variants of the virus; government, social, business and other actions that have been and will be taken in response to the pandemic; any additional waves of the virus; prevalence of vaccines and their ultimate efficacy on new variants of the virus; and the effect of the pandemic on short- and long-term general economic conditions.
26

We are continuing to experience increased prices for commodities such as copper and steel, as well as electrical components. Some materials, such as certain plastics, have also become more difficult to procure due to increased demand or limited availability. We seek to mitigate supply chain risk by maintaining relationships with multiple vendors, and to recoup higher materials costs through adjusted pricing. However, we may not be able to pass on all increased costs, and our suppliers may be unable to provide the materials we require. An inability to procure materials in a timely manner, or to reflect higher materials costs in our pricing to customers, could result in a loss of revenue or lower profit margins, and could have 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 year ended September 30, 2020 for further information.

Consolidated revenues for the three months ended June 30, 2021, were $112.7 million higher than for the three months ended June 30, 2020, an increase of 38.5%, with increases at all four of our operating segments driven by strong demand and the contribution of businesses acquired in fiscal 2021.
Consolidated gross profit for the three months ended June 30, 2021 increased $14.5 million compared to the three months ended June 30, 2020. Our overall gross profit percentage decreased to 17.9% during the three months ended June 30, 2021, as compared to 19.9% during the three months ended June 30, 2020. Gross profit as a percentage of revenue increased at our Commercial & Industrial segment, while decreasing at our Communications, Residential and Infrastructure Solutions 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 June 30, 2021, our selling, general and administrative expenses were $50.3 million, an increase of $6.1 million, or 13.7%, over the three months ended June 30, 2020, driven largely by increased personnel costs at our Residential operating segment in connection with its growth, and by expenses incurred at businesses acquired during fiscal 2021. Selling, general and administrative expense as a percent of revenue decreased from 15.1% for the three months ended June 30, 2020 to 12.4% for the three months ended June 30, 2021, as we benefited from the increased scale of our operations.

Consolidated revenues for the nine months ended June 30, 2021, were $192.2 million higher than for the nine months ended June 30, 2020, an increase of 22.3%, with increases at our Communications, Residential, and Infrastructure Solutions segments, driven by strong demand and the contribution of acquired businesses. Revenues decreased at our Commercial & Industrial segment.
Our overall gross profit percentage increased slightly to 18.7% during the nine months ended June 30, 2021, as compared to 18.6% during the nine months ended June 30, 2020. Gross profit as a percentage of revenue increased at our Communications, Infrastructure Solutions, and Commercial & Industrial segments, but decreased at our Residential segment.

Selling, general and administrative expense as a percent of revenue decreased from 14.4% for the nine months ended June 30, 2020, to 13.4% for the nine months ended June 30, 2021.

Revenues. Our Communications segment’s revenues increased by $19.7 million during the three months ended June 30, 2021, or 20.4%, compared to the three months ended June 30, 2020. The increase primarily resulted from increased demand from our data center and distribution center customers.
Gross Profit. Our Communications segment’s gross profit during the three months ended June 30, 2021 increased by $1.9 million compared to the three months ended June 30, 2020. Gross profit as a percentage of revenue decreased from 19.4% to 17.8% as we invested in hiring and training personnel, particularly in estimating and project management, to grow the business.

Selling, General and Administrative Expenses. Our Communications segment’s selling, general and administrative expenses increased by $1.5 million, or 15.8%, during the three months ended June 30, 2021, compared to the three months ended June 30, 2020. The increase is a result of higher personnel cost, particularly related to higher incentive compensation expense in connection with improved profitability. We also experienced a more typical level of selling expense for the three months ended June 30, 2021 as compared to the same period in 2020, when travel and other activities were curtailed due to the pandemic. Selling, general and administrative expenses as a percentage of revenue in the Communications segment were 9.3% during the three months ended June 30, 2021, compared to 9.7% for the three months ended June 30, 2020.

Revenues. Revenues in our Commercial & Industrial segment increased $7.3 million, or 12.9%, during the three months ended June 30, 2021, compared to the three months ended June 30, 2020. Our Commercial & Industrial segment has been affected by the COVID-19 pandemic, which resulted in delays in awarding new projects and decreased demand for new construction in certain sectors we serve. During the three months ended June 30, 2021, we have started to see more typical levels of activity in the awarding of new contracts. However, this market remains highly competitive.
Gross Profit. Our Commercial & Industrial segment’s gross profit during the three months ended June 30, 2021, increased by $3.2 million, as compared to the three months ended June 30, 2020. We have adjusted our cost structure in response to a highly competitive market, and have improved our procurement process and achieved operating efficiencies on certain projects. Gross profit as a percentage of revenue increased from 8.0% for the three months ended June 30, 2020, to 12.1% for the three months ended June 30, 2021.

Our Commercial & Industrial segment’s selling, general and administrative expenses during the three months ended June 30, 2021 decreased $2.0 million, or 22.8%, compared to the three months ended June 30, 2020 as a result of costs incurred in 2020 to improve our procurement process. For 2021, we have benefited from changes to our cost structure implemented in the prior year, as well as a continued focus on controlling costs. Selling, general and administrative expenses as a percentage of revenue decreased from 15.5% to 10.6% for the three months ended June 30, 2021 compared to the three months ended June 30, 2020, as we benefited from the increased scale of our operations, as well as an improved cost structure.

Revenues. Revenues in our Commercial & Industrial segment decreased $11.8 million during the nine months ended June 30, 2021, or 6.2%, compared to the nine months ended June 30, 2020. The decrease was largely driven by a reduction in time-and-material work, as well as lower demand for large, agricultural projects. The market for our Commercial & Industrial segment's services remains highly competitive, and disruptions caused by the COVID-19 pandemic resulted in some delays in the awarding of new projects and the progress of certain existing projects, as well as decreased demand for new construction in certain sectors we serve, particularly through the first six months of fiscal 2021. However, we have seen an increase in activity during the past few months, as many of our customers have reverted to more typical levels of activity.
Gross Profit. Our Commercial & Industrial segment’s gross profit during the nine months ended June 30, 2021 increased by $3.3 million, or 20.7%, as compared to the nine months ended June 30, 2020. We have improved project efficiency and our procurement process, and as a result, gross profit as a percentage of revenue increased from 8.3% for the nine months ended June 30, 2020, to 10.7% for the nine months ended June 30, 2021.

Selling, General and Administrative Expenses. Our Commercial & Industrial segment’s selling, general and administrative expenses during the nine months ended June 30, 2021 decreased $4.7 million, or 19.1%, compared to the nine months ended June 30, 2020. The higher expense in fiscal 2020 primarily reflected a write-off recorded in 2020 related to a commercial dispute, as well as cost incurred in 2020 to improve our procurement process. Selling, general and administrative expenses as a percentage of revenue decreased despite lower volumes, from 12.9% for the nine months ended June 30, 2020 to 11.2% for the nine months ended June 30, 2021.

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 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.
REMAINING PERFORMANCE OBLIGATIONS AND BACKLOG
Remaining performance obligations represent the unrecognized revenue value of our contract 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:

|  | June 30, |  | March 31, |  | December 31, |  | September 30,
|  | 2021 |  | 2021 |  | 2020 |  | 2020
Remaining performance obligations |  | $ | 669 |  |  | $ | 614 |  |  | $ | 525 |  |  | $ | 505 |
Agreements without an enforceable obligation (1) |  |  | 156 |  |  |  | 93 |  |  |  | 107 |  |  |  | 97 |
Backlog |  | $ | 825 |  |  | $ | 707 |  |  | $ | 632 |  |  | $ | 602 |
(1) Our backlog contains signed agreements and letters of intent, which we do not have a legal right to enforce prior to work starting. These arrangements are excluded from remaining performance obligations until work begins.

WORKING CAPITAL
During the nine months ended June 30, 2021, working capital exclusive of cash increased by $41.8 million from September 30, 2020, reflecting an $88.8 million increase in current assets excluding cash and a $47.1 million increase in current liabilities during the period.
During the nine months ended June 30, 2021, our current assets exclusive of cash increased to $406.7 million, as compared to $317.9 million as of September 30, 2020, primarily as a result of a $46.7 million increase in inventory. Certain materials we carry in inventory, particularly copper wire, have increased in price. Further, we have increased the quantity of inventory we are currently carrying to manage procurement risks, as some of our key suppliers have increased lead times necessary to fill our orders. We also acquired $12.9 million of inventory in business combinations during the nine months ended June 30, 2021. Prepaid expenses and other current assets increased by $11.0 million, largely as a result of deposits made to secure future deliveries of materials. A seasonal increase in accounts receivable, as well as the addition of accounts receivable at acquired businesses, drove a $30.8 million increase in trade accounts receivable. Days sales outstanding reduced to 54 at June 30, 2021 from 61 at September 30, 2020. 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.
During the nine months ended June 30, 2021, our total current liabilities increased by $47.1 million to $289.5 million, compared to $242.4 million as of September 30, 2020, primarily related to an increase in accounts payable and accrued liabilities. A seasonal increase in accounts payable and accrued liabilities, as well as current liabilities at businesses acquired, drove the increase.
Surety
We believe the bonding capacity provided by our sureties is adequate for our current operations and will be adequate for our operations for the foreseeable future. As of June 30, 2021, the estimated cost to complete our bonded projects was approximately $98.3 million.
LIQUIDITY AND CAPITAL RESOURCES
The Revolving Credit Facility
We maintain a $100 million revolving credit facility pursuant to a credit agreement with Wells Fargo Bank, N.A. ("Wells Fargo") that matures on September 30, 2024 (as amended, the "Amended Credit Agreement").
The Amended Credit Agreement contains customary affirmative, negative and financial covenants as well as events of default.
As of June 30, 2021, 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 (as defined in the Amended Credit Agreement) of at least 20% of the Maximum Revolver Amount (as defined in the Amended Credit Agreement), or $20 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 June 30, 2021, our Liquidity was $81.8 million, our Excess Availability was $64.3 million (or greater than 50% of minimum Liquidity), and our Fixed Charge Coverage Ratio was 20.4:1.0.
If in the future our Liquidity falls below $20 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 June 30, 2021, we had $4.5 million in outstanding letters of credit with Wells Fargo and outstanding borrowings of $30.5 million 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.
Operating activities provided net cash of $35.1 million during the nine months ended June 30, 2021, as compared to $55.6 million of net cash provided in the nine months ended June 30, 2020. The decrease in operating cash flow resulted from an increase in working capital, particularly related to inventory. As commodity prices have increased, we have also experienced longer lead times for deliveries, and reduced availability for certain products we procure, particularly copper wire. As a result, we have increased the amount of inventory we are currently carrying in an effort to ensure the availability of materials to serve our customers. This increase in working capital was partly offset by higher earnings during the nine months ended June 30, 2021.
Investing Activities
Net cash used in investing activities was $97.9 million for the nine months ended June 30, 2021, compared to $32.6 million for the nine months ended June 30, 2020. We used $92.7 million for business acquisitions and $5.4 million for capital expenditures in the nine months ended June 30, 2021. For the nine months ended June 30, 2020, we used $29.0 million to complete two acquisitions and $3.7 million for capital expenditures.
Financing Activities
Net cash used in financing activities for the nine months ended June 30, 2021 was $27.7 million, compared to $6.1 million provided by financing activities for the nine months ended June 30, 2020. Net cash used by financing activities included $1.5 million used to repurchase our shares to satisfy statutory withholding requirements upon the vesting of employee stock compensation. We also paid $1.5 million to noncontrolling interest holders, $1.2 million of which was used to purchase the remaining equity interests in STR Mechanical, LLC. For the nine months ended June 30, 2020, we drew $592.6 million and repaid $592.6 million on our revolving credit facility. Additionally, we used $5.4 million for market repurchases under our stock repurchase plan as well as to repurchase our shares to satisfy statutory withholding requirements upon the vesting of employee stock compensation.
Stock Repurchase Program
In 2015, our Board authorized a stock repurchase program for the purchase from time to time of up to 1.5 million shares of the Company’s common stock, and on May 2, 2019, our Board authorized the repurchase from time to time of up to an additional 1.0 million shares of the Company's common stock under the stock 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 or reinstated at any time at the Company’s discretion and without notice. We repurchased no shares pursuant to this program during the nine months ended June 30, 2021.
OFF-BALANCE SHEET ARRANGEMENTS AND CONTRACTUAL OBLIGATIONS
From time to time, we may enter into firm purchase commitments for materials, such as copper or aluminum wire, which we expect to use in the ordinary course of business. These commitments are typically for terms of less than one year and require us to buy minimum quantities of materials at specific intervals at a fixed price over the term. As of June 30, 2021, we had commitments of $13.8 million outstanding under such agreements to purchase copper wire over the next four months in the ordinary course of business. There have been no other material changes in our contractual obligations and commitments from those disclosed in our Annual Report on Form 10-K for the fiscal year ended September 30, 2020.

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 for copper, aluminum, steel 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. 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, 2020, and Part II, Item 1A "Risk Factors" of our Quarterly Report on Form 10-Q for the fiscal quarter ended March 31, 2021.
Commodity Risk
Our exposure to significant market risks includes fluctuations in commodity prices for copper, aluminum, steel and fuel. Commodity price risks may have an impact on our results of operations due to the fixed 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 construction industry will allow.
Interest Rate Risk
Floating rate debt, where the interest rate fluctuates periodically, exposes us to short-term changes in market interest rates. All of the long-term debt outstanding 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. If LIBOR or its replacement benchmark were to increase, our interest payment obligations on any then-outstanding borrowings would increase, having a negative effect on our cash flow and financial condition. A one percentage point increase in the interest rate on our long-term debt outstanding under the credit facility as of June 30, 2021 would cause a $0.3 million pre-tax annual increase in interest expense.
In July 2017, the Financial Conduct Authority (the “FCA”), the regulatory authority over LIBOR, stated that it would phase out LIBOR as a benchmark after 2021 to allow for an orderly transition to an alternative reference rate. In November 2020, the ICE Benchmark Administration (the “IBA”) announced that it intends to continue publishing LIBOR until the end of June 2023, beyond the previously announced 2021 cessation date. The IBA announcement was supported by announcements from the FCA and the Board of Governors of the Federal Reserve System, Federal Deposit Insurance Corporation and Office of the Comptroller of the Currency (collectively, the “U.S. Regulators”). However, both the FCA and U.S. Regulators in their announcements also advised banks to cease entering into new contracts referencing LIBOR after December 2021. These announcements indicate that the continuation of LIBOR on the current basis may not be assured after 2021 and will not be assured beyond June 2023. In light of these recent announcements, the future of LIBOR at this time is uncertain, and any changes in the methods by which LIBOR is determined or regulatory activity related to LIBOR’s phase-out could cause LIBOR to perform differently than in the past or cease to exist.
In the United States, the Alternative Reference Rates Committee (the working group formed to recommend an alternative rate to LIBOR) has identified the Secured Overnight Financing Rate ("SOFR") as its preferred alternative rate for LIBOR. On July 29, 2021, the Alternative Reference Rates Committee announced that it is formally recommending SOFR term rates. Even with this update, there can be no guarantee that SOFR will become a widely-accepted benchmark in place of LIBOR. Although the full impact of the transition away from LIBOR, including the discontinuance of LIBOR publication and the adoption of SOFR as the replacement rate for LIBOR, remains unclear, these changes may have an adverse impact on our floating rate indebtedness and financing costs under our revolving credit facility.
Our Amended Credit Agreement provides for a mechanism to amend the facility to reflect the establishment of an alternative rate of interest upon the occurrence of certain events related to the phase-out of LIBOR. However, we have not yet pursued any technical amendment or other contractual alternative to address this matter and are currently evaluating the impact of the potential replacement of the LIBOR interest rate.
