NOTE 1 - ORGANIZATION
Installed Building Products (“IBP”), a Delaware corporation formed on October 28, 2011, and its wholly-owned subsidiaries (collectively referred to as the “Company,” and “we,” “us” and “our”) primarily install insulation, waterproofing, fire-stopping, fireproofing, garage doors, rain gutters, window blinds, shower doors, closet shelving and mirrors and other products for residential and commercial builders located in the continental United States. The Company operates in more than 250 locations and its corporate office is located in Columbus, Ohio.
The vast majority of our sales originate from our one reportable segment, Installation. Substantially all of our Installation segment sales are derived from the service-based installation of various products in the residential new construction, repair and remodel and commercial construction end markets from our national network of branch locations. Each of our Installation branches has the capacity to serve all of our end markets. See Note 3, Revenue Recognition, for information on our revenues by product and end market, and see Note 10, Information on Segments, for information on how we segment the business.
NOTE 2 - SIGNIFICANT ACCOUNTING POLICIES
Basis of Presentation and Principles of Consolidation
The accompanying consolidated financial statements include all of our wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated.
The information furnished in the Condensed Consolidated Financial Statements includes normal recurring adjustments and reflects all adjustments which are, in the opinion of management, necessary for a fair presentation of the results of operations and statements of financial position for the interim periods presented. Certain information and footnote disclosures normally included in the consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and the rules and regulations of the Securities and Exchange Commission (the “SEC”) have been omitted pursuant to such rules and regulations. We believe that the disclosures are adequate to prevent the information presented from being misleading when read in conjunction with our audited consolidated financial statements and the notes thereto included in Part II, Item 8, Financial Statements and Supplementary Data, of our Annual Report on Form 10-K for the fiscal year ended December 31, 2024 (“2024 Form 10-K”), as filed with the SEC on February 27, 2025. The December 31, 2024 Condensed Consolidated Balance Sheet data herein was derived from the audited consolidated financial statements, but the related footnotes do not include all disclosures required by U.S. GAAP.
Our interim operating results for the three and nine months ended September 30, 2025 are not necessarily indicative of the results to be expected in future operating quarters.
Note 2 to the audited consolidated financial statements in our 2024 Form 10-K describes the significant accounting policies and estimates used in preparation of the audited consolidated financial statements. There have been no changes to our significant accounting policies during the nine months ended September 30, 2025.

Contract Assets and Liabilities
Our contract assets consist of unbilled amounts typically resulting from sales under contracts when the cost-to-cost method of revenue recognition is utilized and revenue recognized, based on costs incurred, exceeds the amount billed to the customer. Our contract assets are recorded in other current assets in our Condensed Consolidated Balance Sheets. Our contract liabilities consist of customer deposits and billings in excess of revenue recognized, based on costs incurred and are included in other current liabilities in our Condensed Consolidated Balance Sheets.
Contract assets and liabilities related to our uncompleted contracts and customer deposits were as follows (in millions):

| September 30, 2025 |  | December 31, 2024
Contract assets | $ | 34.4 |  |  | $ | 33.2 |
Contract liabilities | (21.9) |  |  | (19.7) |

Uncompleted contracts were as follows (in millions):

| September 30, 2025 |  | December 31, 2024
Costs incurred on uncompleted contracts | $ | 196.0 |  |  | $ | 248.4 |
Estimated earnings | 139.5 |  |  | 128.5 |
Total | 335.5 |  |  | 376.9 |
Less: Billings to date | 312.7 |  |  | 352.9 |
Net under billings | $ | 22.8 |  |  | $ | 24.0 |

Net under billings were as follows (in millions):

| September 30, 2025 |  | December 31, 2024
Costs and estimated earnings in excess of billings on uncompleted contracts (contract assets) | $ | 34.4 |  |  | $ | 33.2 |
Billings in excess of costs and estimated earnings on uncompleted contracts (contract liabilities) | (11.6) |  |  | (9.2) |
Net under billings | $ | 22.8 |  |  | $ | 24.0 |

The difference between contract assets and contract liabilities as of September 30, 2025 compared to December 31, 2024 is primarily the result of timing differences between our performance of obligations under contracts and customer payments and billings. During the three and nine months ended September 30, 2025, we recognized $0.5 million and $18.8 million of revenue that was included in the contract liability balance at December 31, 2024. We did not recognize any impairment losses on our contract assets during the three and nine months ended September 30, 2025 or 2024.

Remaining performance obligations represent the transaction price of contracts for which work has not been performed and excludes unexercised contract options and potential modifications. As of September 30, 2025, the aggregate amount of the transaction price allocated to remaining uncompleted contracts was $159.9 million. We expect to satisfy remaining performance obligations and recognize revenue on substantially all of these uncompleted contracts over the next 18 months.
NOTE 4 - CREDIT LOSSES
Our expected loss allowance methodology for accounts receivable is developed using historical experience, present economic conditions and other factors management considers relevant to estimate expected credit losses.

Current period provision | 6.1 |
Recoveries collected and additions | 0.4 |
Amounts written off | (4.0) |
Balance as of September 30, 2025 | $ | 13.2 |

NOTE 5 - CASH AND CASH EQUIVALENTS
Cash and cash equivalents include money market funds which are highly liquid instruments with insignificant interest rate risk and original or remaining maturities of three months or less at the time of purchase. These money market funds amounted to approximately $285.9 million and $296.7 million as of September 30, 2025 and December 31, 2024, respectively. See Note 9, Fair Value Measurements, for additional information.
NOTE 6 - GOODWILL AND INTANGIBLES

NOTE 9 - FAIR VALUE MEASUREMENTS
Assets and Liabilities Measured at Fair Value on a Recurring Basis
In many cases, a valuation technique used to measure fair value includes inputs from multiple levels of the fair value hierarchy. The lowest level of significant input determines the placement of the entire fair value measurement in the hierarchy. During the periods presented, there were no transfers between fair value hierarchical levels.
Assets Measured at Fair Value on a Nonrecurring Basis
Certain assets, specifically other intangible and long-lived assets, are measured at fair value on a nonrecurring basis in periods subsequent to initial recognition. Assets measured at fair value on a nonrecurring basis as of September 30, 2025 and December 31, 2024 are categorized based on the lowest level of significant input to the valuation. The assets are measured at fair value when our impairment assessment indicates a carrying value for each of the assets in excess of the asset’s estimated fair value. Undiscounted cash flows, a Level 3 input, are utilized in determining estimated fair values. During the three and nine months ended September 30, 2025, we did not record any impairments on these assets required to be measured at fair value on a nonrecurring basis. Certain long-lived assets were impaired based on estimated future cash flows due to the wind down of a single branch during the nine months ended September 30, 2024.
The table below presents asset impairment information related to long-lived assets during the nine months ended September 30, 2024 (in millions):

Property and equipment assets impairment |  |  |  |  |  |  | $ | 0.2 |
Right-of-use assets impairment |  |  |  |  |  |  | 0.1 |
Intangible assets impairment |  |  |  |  |  |  | 4.6 |
Total asset impairments |  |  |  |  |  |  | $ | 4.9 |

Estimated Fair Value of Financial Instruments
Accounts receivable, accounts payable and accrued liabilities as of September 30, 2025 and December 31, 2024 approximate fair value due to the short-term maturities of these financial instruments. The carrying amounts of certain long-term debt, including the Term Loan and ABL Revolver as of September 30, 2025 and December 31, 2024, approximate fair value due to the variable rate nature of the agreements. The carrying amounts of our operating lease right-of-use assets and the obligations associated with our operating and finance leases as well as our vehicle and equipment notes approximate fair value as of September 30, 2025 and December 31, 2024. All debt classifications represent Level 2 fair value measurements. Derivative financial instruments are measured at fair value based on observable market information and appropriate valuation methods.
Contingent consideration liabilities arise from future earnout payments to the sellers associated with certain acquisitions and are based on predetermined calculations of certain future results. These future payments are estimated by considering various factors, including business risk and projections. The contingent consideration liabilities are measured at fair value by discounting estimated future payments, calculated based on a weighted average of various future forecast scenarios, to their net present value.
The fair values of financial assets and liabilities that are recorded at fair value in the Condensed Consolidated Balance Sheets and not described above were as follows (in millions):

NOTE 10 - INFORMATION ON SEGMENTS
Our Chief Executive Officer is our Chief Operating Decision Maker ("CODM") who reviews financial information for each of our three operating segments, consisting of Installation, Distribution and Manufacturing, for the purpose of assessing business performance, managing the business and allocating resources.
Our Installation operating segment represents the majority of our net revenue and gross profit and forms our one reportable segment. This operating segment represents the service-based installation of insulation and complementary building products in the residential new construction, repair and remodel and commercial construction end markets from our national network of branch locations. These branch locations have similar economic and operating characteristics including the nature of products and services offered, operating procedures and risks, customer bases, employee incentives, material procurement and shared corporate resources which led us to conclude that they combine to form one operating segment.
The Other category reported below reflects the operations of our two remaining operating segments, Distribution and Manufacturing, which do not meet the quantitative thresholds for separate reporting. Our Distribution operating segment includes our distribution businesses that sell insulation, gutters and accessories primarily to installers of these products who operate in multiple end markets. Our Manufacturing operating segment consists of our manufacturing operations which produce cellulose insulation and asphalt and industrial fibers to sell to distributors and installers of these products.
The Installation reportable segment includes substantially all of our net revenue from services while net revenue included in the Other category includes substantially all of our net revenue from sales of products. The intercompany sales from the Other category to the Installation reportable segment include a profit margin while our Installation segment records these transactions at cost. These transactions are shown in the reconciliation of revenue and segment gross profit below.
The key metrics used by our CODM to assess performance, review results and allocate resources of our operating segments are revenue and segment gross profit. Our CODM reviews segment gross profit for each of our segments separately and uses this metric to guide operating decisions and business strategy. We define segment gross profit as revenue less cost of sales, excluding depreciation and amortization. We do not report depreciation, amortization, operating expenses, other expense, net or total assets by segment because our CODM does not regularly receive or use this information. The following tables represent our Installation segment information for the three and nine months ended September 30, 2025 and 2024 (in millions):

NOTE 11 - DERIVATIVES AND HEDGING ACTIVITIES
Cash Flow Hedges of Interest Rate Risk
Our purpose for using interest rate derivatives is to add stability to interest expense and to manage our exposure to interest rate movements. During the nine months ended September 30, 2025, we used interest rate swaps to hedge the variable cash flows associated with existing variable-rate debt. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. We do not use derivatives for trading or speculative purposes and we currently do not have any derivatives that are not designated as hedges. As of September 30, 2025, we have not posted any collateral related to these agreements.

As of September 30, 2025 and December 31, 2024, we had the following interest rate swap derivatives (notional amounts in millions):

Effective Date |  | Notional Amount |  | Fixed Rate |  | Maturity Date
April 28, 2023 |  | $ | 200.0 |  |  | 0.46 | % |  | December 31, 2025

December 31, 2025 |  | 100.0 |  |  | 2.93 | % |  | December 14, 2028

As of September 30, 2025, our two forward interest rate swaps, combined with our three active swaps, serve to hedge $400.0 million of the variable cash flows on our variable rate Term Loan through December 14, 2028. The assets associated with these interest rate swaps are included in other current assets and other non-current assets on the Condensed Consolidated Balance Sheets at their fair value amounts as described in Note 9, Fair Value Measurements.
In July 2022, we amended the maturity date of each of our three active interest rate swaps to December 31, 2025 with other terms remaining unchanged. The remaining unrealized gains will be amortized as a decrease to interest expense, net through the original maturity dates of April 15, 2030 and December 15, 2028. For each of the three months ended September 30, 2025 and 2024, we amortized $1.8 million, respectively, and for each of the nine months ended September 30, 2025 and 2024, we amortized $5.3 million, respectively, of the remaining unrealized gains as a decrease to interest expense, net.
During the three and nine months ended September 30, 2024, we amorti zed $1.0 million and $3.1 million, respectively, and during the nine months ended September 30, 2025, we amortized $1.2 million of the remaining unrealized losses associated with the August 2020 terminated swaps as an increase to interest expense, net. All losses were fully amortized as of April 15, 2025.
The amended swaps included off-market terms at inception. This other-than-insignificant financing element will be amortized as an increase to interest expense, net through the December 31, 2025 maturity date of the amended swaps. For each of the three months ended September 30, 2025 and 2024, we amortized $1.8 million, respectively, and for each of the nine months ended September 30, 2025 and 2024, we amortized $5.5 million, respectively, of the financing element as an increase to interest expense, net. Future net c ash settlements with interest rate counterparties are recognized through cash flows from investing activities in the Condensed Consolidated Statements of Cash Flows due to the other-than-insignificant financing element.
The changes in the fair value of derivatives designated, and that qualify, as cash flow hedges are recorded in other comprehensive loss, net of tax on the Condensed Consolidated Statements of Operations and Comprehensive Income and in accumulated other comprehensive income on the Condensed Consolidated Balance Sheets and subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. We had no such changes during the nine months ended September 30, 2025 and 2024.
Amounts reported in accumulated other comprehensive income related to derivatives will be reclassified to interest expense, net as interest payments are made on our variable-rate debt, and as our terminated and amended swaps are amortized. Over the next twelve months, we estimate that an additional $9.5 million will be reclassified as a decrease to interest expense, net.
The following table summarizes amounts recorded to interest expense, net included in the Condensed Consolidated Statements of Operations and Comprehensive Income related to our interest rate swaps (in millions):

| Three months ended September 30, |  | Nine months ended September 30,

Share repurchases
During the three months ended September 30, 2025, we repurchased 200 thousand shares of our common stock with an aggregate price of approximately $51.5 million, or $257.38 price per share. Repurchases during the nine months ended September 30, 2025 amounted to 700 thousand shares of our common stock with an aggregate price of approximately $134.9 million, or $192.75 average price per share. The effect of these treasury shares in reducing the number of common shares outstanding is reflected in our earnings per share calculation. During the three months ended September 30, 2024, we repurchased 100 thousand shares of our common stock with an aggregate price of approximately $20.7 million, or $206.90 price per share. Repurchases during the nine months ended September 30, 2024 amounted to approximately 315 thousand shares of our common stock with an aggregate price of approximately $66.4 million, or $210.94 average price per share.
On February 27, 2025, we announced that our board of directors authorized a new stock repurchase program that allows for the repurchase of up to $500.0 million of our outstanding common stock. The new program replaces the previous program and is in effect through March 1, 2026.

The amount of dividends declared may vary from the amount of dividends paid in a period due to the vesting of restricted stock awards and performance share awards, which accrue dividend equivalent rights that are paid when the award vests. During the nine months ended September 30, 2025 and 2024, we also paid $0.8 million and $0.5 million, respectively, in accrued

Retirement Plans
We participate in multiple 401(k) plans, whereby we provide a matching contribution of wages deferred by employees and can also make discretionary contributions to each plan. Certain plans allow for discretionary employer contributions only. These plans cover substantially all our eligible employees. We recognized 401(k) plan expenses of $0.5 million and $0.7 million during the three months ended September 30, 2025 and 2024, respectively, and $2.4 million and $2.6 million for the nine months ended September 30, 2025 and 2024, respectively.

Share-Based Compensation
Common Stock Awards
We periodically grant shares of our common stock to non-employee members of our board of directors and our employees. We granted approximately five thousand and four thousand shares during the nine months ended September 30, 2025 and 2024, respectively, under our 2023 Omnibus Incentive Plan to non-employee members of our board of directors.
In addition, we granted approximately two thousand and 77 thousand shares of our common stock to employees during the three and nine months ended September 30, 2025, respectively, and seven thousand and 37 thousand shares of our common stock to employees during the three and nine months ended September 30, 2024, respectively.
Employees – Performance-Based Stock Awards
During the nine months ended September 30, 2025, we issued approximately 34 thousand shares of our common stock to certain officers, which vest in two equal installments on each of April 20, 2026 and April 20, 2027. In addition, during the nine months ended September 30, 2025, we established, and our board of directors approved, performance-based targets in connection with common stock awards to be issued to certain officers in 2026 contingent upon achievement of these targets.
In addition, there are various performance-based bonus plans for certain employees to be issued through the 2029 performance period that are accounted for as liability-based awards since they represent a predominantly-fixed monetary amount that will be settled with a variable number of common shares contingent upon achievement of certain performance targets. Some of these awards will vest in 2030 if achieved. During the nine months ended September 30, 2025 and 2024, we issued approximately 11 thousand and four thousand shares of our common stock, respectively, which both vested in the second quarter of 2025.
Employees – Performance-Based Restricted Stock Units
During 2024, we established, and our board of directors approved, performance-based restricted stock units in connection with common stock awards which were issued to certain employees in 2025 based upon achievement of a performance target. In addition, during the nine months ended September 30, 2025, we established, and our board of directors approved, performance-based restricted stock units in connection with common stock awards to be issued to certain employees in 2026 based upon achievement of a performance target. These units will be accounted for as equity-based awards that will be settled with a fixed number of common shares.

September 30, 2024, our effective tax rate was 26.9% and 26.2%, respectively. The rates for the three and nine months ended September 30, 2024 were based on an estimated annual effective tax rate and the rate for the nine months ended September 30, 2024 was favorably impacted by recognition of a windfall tax benefit from equity vesting.
In July 2025, the One Big Beautiful Bill Act (the "OBBB Act") was enacted in the United States. The OBBB Act made permanent certain key provisions from the 2017 Tax Cuts and Jobs Act, with other provisions becoming effective through 2027. We do not expect the OBBB Act to have a material impact to our 2025 effective tax rate as a result of its enactment.

Leases
See Note 8, Leases, for further information regarding our lease commitments.
Other Commitments and Contingencies
From time to time, various claims and litigation are asserted or commenced against us principally arising from contractual matters and personnel and employment disputes. In determining loss contingencies, management considers the likelihood of loss as well as the ability to reasonably estimate the amount of such loss or liability. An estimated loss is recorded when it is considered probable that such a liability has been incurred and when the amount of loss can be reasonably estimated. As litigation is subject to inherent uncertainties, we cannot be certain that we will prevail in these matters. However, we do not believe that the ultimate outcome of any pending matters will have a material adverse effect on our consolidated financial position, results of operations or cash flows.
We have an agreement with one of our suppliers to purchase a portion of the materials we utilize in our business with variable pricing . This agreement is effective March 31, 2023 through May 15, 2026 with a purchase obligation of 12.0 million pounds for the period ending May 15, 2024, 14.4 million pounds for the period ending May 15, 2025 and 17.3 million pounds for the period ending March 31, 2026. During the nine months ended September 30, 2025, we entered into an amendment which reduced our 17.3 million pounds commitment to 12.3 million pounds and amended the period commitment to May 15, 2026. Through September 30, 2025, we satisfied the agreement for the period ending May 15, 2025 and purchased approximately 4.3 million pounds of materials under the agreement for the period ending May 15, 2026.
We also have a contract with a supplier to purchase various products we employ in our business with fixed rate pricing. The agreement is effective January 1, 2025 through December 31, 2027 with a purchase obligation of 8.0 million pounds for each of the periods ending December 31, 2025, 2026 and 2027, and a total minimum commitment of $10.8 million. During the nine months ended September 30, 2025, we purchased approximately 7.7 million pounds of materials under this agreement for the period ending December 31, 2025.
During the nine months ended September 30, 2025, we entered into a purchase agreement with one of our suppliers to purchase certain products we utilize in our business. This agreement includes variable pricing terms and is effective July 1, 2025 with a volume commitment of 40.6 million pounds for the remainder of 2025. The volume commitment increases to 89.1 million pounds in 2026 and is subject to adjustments in future periods beyond 2026, conditional upon certain contingencies, for a period of five years. During the three months ended September 30, 2025, we purchased approximately 23.9 million pounds of materials under this agreement for the period ending December 31, 2025.

NOTE 17 - BUSINESS COMBINATIONS
As part of our ongoing strategy to expand geographically and increase market share in certain markets, as well as diversify our products and end markets, we completed three business combinations and four insignificant bolt-on acquisitions merged into existing operations during the nine months ended September 30, 2025 and six business combinations and one insi gnificant bolt-on acquisition merged into an existing operation during the nine months ended September 30, 2024. The largest of these acquisitions were Carolina Precision ACP, LLC ("Carolina Precision Fibers") in September 2025 and Euroview Enterprises, LLC and Contract Mirror and Supply, LLC (collectively, "Euroview") in July 2024.
Below is a summary of acquisitions in aggregate by year, including revenue and net income since date of acquisition shown for the year of acquisition. Net income includes amortization and taxes when appropriate.
For the three and nine months ended September 30, 2025 (in millions):

Acquisition-related costs recorded within administrative expenses on the Condensed Consolidated Statements of Operations and Comprehensive Income amounted to $0.8 million and $0.5 million for the three months ended September 30, 2025 and 2024, respectively, and $1.8 million and $1.6 million for the nine months ended September 30, 2025 and 2024, respectively.
The goodwill recognized in conjunction with these business combinations represents the excess cost of the acquired entity over the net amount assigned to assets acquired and liabilities assumed (including the identifiable intangible assets). The goodwill recognized for Carolina Precision Fibers reflects the value of its manufacturing capabilities, supplier relationships and other synergies from combining operations that are expected to be realized from the acquisition. The goodwill recognized for Euroview represents the advantage of its product lines, human capital, geographic presence and other benefits that are expected to be achieved from the acquisition. We expect to deduct approximately $10.7 million of goodwill for tax purposes as a result of 2025 acquisitions.

Contingent consideration, non-compete agreements and/or amounts based on working capital calculations are included as “seller obligations” in the above table or within “fair value of assets acquired” if subsequently paid during the period presented. Contingent consideration payments consist primarily of earnouts based on performance that are recorded at fair value at the time of acquisition. When these payments are expected to be made over one year from the acquisition date, the contingent consideration is discounted to net present value of future payments based on a weighted average of various future forecast scenarios.
Further adjustments to the allocation for each acquisition still under its measurement period are expected as third-party or internal valuations are finalized, certain tax aspects of the transaction are completed and customary post-closing reviews are concluded during the measurement period attributable to each individual business combination. As a result, adjustments to the fair value of assets acquired, and in some cases total purchase price, have been made to certain business combinations since the date of acquisition and future adjustments may be made through the end of each measurement period. Any acquisition acquired after September 30, 2024 is deemed to be within the measurement period and its purchase price considered preliminary.
Goodwill and intangibles per the above table may not agree to the total gross increase of these assets as shown in Note 6, Goodwill and Intangibles, during each of the nine months ended September 30, 2025 and 2024 due to adjustments to goodwill for the allocation of certain acquisitions still under measurement as well as intangible impairment charges and other immaterial intangible assets added during the ordinary course of business. All of the goodwill for Carolina Precision Fibers was assigned to our Manufacturing operating segment. One immaterial acquisition also had its respective goodwill assigned to Other during the nine months ended September 30, 2024. All other acquisitions during the nine months ended September 30, 2025 and 2024 had their respective goodwill assigned to our Installation operating segment.

Pro Forma Information
The unaudited pro forma information for the combined results of the Company has been prepared as if the 2025 acquisitions had taken place on January 1, 2024 and the 2024 acquisitions had taken place on January 1, 2023. The unaudited pro forma information is not necessarily indicative of the results that we would have achieved had the transactions actually taken place on January 1, 2024 and 2023, respectively, and the unaudited pro forma information does not purport to be indicative of future financial operating results (in millions, except per share data):

| Unaudited pro forma for the three months ended September 30, |  | Unaudited pro forma for the nine months ended September 30,
| 2025 |  | 2024 |  | 2025 |  | 2024
Net revenue | $ | 782.6 |  |  | $ | 783.0 |  |  | $ | 2,239.3 |  |  | $ | 2,274.3 |
Net income | 75.0 |  |  | 70.4 |  |  | 190.6 |  |  | 196.4 |
Basic net income per share | 2.77 |  |  | 2.52 |  |  | 6.98 |  |  | 6.99 |
Diluted net income per share | 2.76 |  |  | 2.50 |  |  | 6.95 |  |  | 6.95 |

Unaudited pro forma net income reflects additional intangible asset amortization expense of approximately $0.1 million and $1.0 million for the three months ended September 30, 2025 and 2024, respectively, and $0.8 million and $3.8 million for the nine months ended September 30, 2025 and 2024, respectively, as well as additional income tax expense of approximately $0.2 million and $0.6 million for the three months ended September 30, 2025 and 2024, respectively, and $0.6 million and $2.2 million for the nine months ended September 30, 2025 and 2024, respectively, that would have been recorded had the 2025 acquisitions taken place on January 1, 2024 and the 2024 acquisitions taken place on January 1, 2023.
NOTE 18 - INCOME PER COMMON SHARE
Basic net income per common share is calculated by dividing net income by the weighted average shares outstanding during the period, without consideration for common stock equivalents.
Diluted net income per common share is calculated by adjusting weighted average shares outstanding for the dilutive effect of common stock equivalents outstanding for the period, determined using the treasury stock method. Potential common stock is included in the diluted income per common share calculation when dilutive. The dilutive effect of outstanding restricted stock awards after application of the treasury stock method was approximately 101 thousand and 120 thousand shares for the three and nine months ended September 30, 2025, respectively, and 130 thousand and 162 thousand shares for the three and nine months ended September 30, 2024, respectively. Approximately one thousand and six thousand weighted average shares of potential common stock were not included in the calculation of diluted weighted average shares outstanding for the three and nine months ended September 30, 2025, respectively, because the effect would have been anti-dilutive. Such shares were not material for the three and nine months ended September 30, 2024.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations
This Management’s Discussion and Analysis of Financial Condition and Results of Operations should be read in conjunction with our condensed consolidated financial statements and related notes in “Item 1. Financial Statements” of this Quarterly Report on Form 10-Q, as well as our 2024 Form 10-K.
OVERVIEW
We are one of the nation’s largest insulation installers for the residential new construction market and are also a diversified installer of complementary building products throughout the United States, including waterproofing, fire-stopping and fireproofing, garage doors, rain gutters, window blinds, shower doors, closet shelving, mirrors and other products. We offer our portfolio of services for new and existing single-family and multi-family residential and commercial building projects in all 48 continental states and the District of Columbia from our national network of over 250 branch locations. During the three months ended September 30, 2025, 93% of our net revenue came from the service-based installation of these products across all of our end markets which forms our Installation operating segment and single reportable segment. In addition, three regional distribution operations serve the Midwest, Mountain West, Northeast and Mid-Atlantic regions of the United States, and we operate two cellulose insulation manufacturing facilities. We believe our business is well positioned to continue to profitably grow over the long-term due to our strong balance sheet, liquidity and our continuing acquisition strategy.
A large portion of our net revenue comes from the U.S. residential new construction market, which depends upon a number of economic factors, including demographic trends, interest rates, inflation, consumer confidence, employment rates, housing inventory levels and affordability, foreclosure rates, the health of the economy and availability of mortgage financing.
2025 Third Quarter Highlights
Net revenue increased 2.3%, or $17.6 million to $778.2 million, while gross profit increased 2.9% to $264.2 million during the three months ended September 30, 2025 compared to 2024. The increase in net revenue was primarily due to the 11.7% increase in commercial end market same branch sales growth and the contribution of our recent acquisitions, partially offset by a decline in Installation job volume and sales decreases in the residential end markets. The increase in gross profit was primarily driven by selling price and product mix improvements and improved material costs. Specifically, gross profit outpaced sales growth due to higher selling prices compared to the prior year as we continued to prioritize profitability over sales volume. Certain net revenue and industry metrics we use to monitor our operations are discussed in the "Key Measures of Performance" section below, and further details regarding results of our various end markets are discussed further in the "Net Revenue, Cost of Sales and Gross Profit" section below.
As of September 30, 2025, we had $333.3 million of cash and cash equivalents and we have not drawn on our revolving line of credit. This strong liquidity position allowed us to return capital to shareholders by increasing our regular quarterly dividend 6% over the third quarter of 2024 to $0.37 per share, or $10.1 million in the aggregate. Additionally, we repurchased $51.5 million of our outstanding common stock during the three months ended September 30, 2025 for a total capital return to shareholders of $61.6 million.
Key Measures of Performance
We utilize certain net revenue and industry metrics to monitor our operations. Key metrics include total sales growth and same branch growth metrics for our consolidated results, our Installation reportable segment and our Other category consisting of our Distribution and Manufacturing operating segments. We also monitor sales growth for our Installation segment by end market and track volume growth and price/mix growth.
We believe the revenue growth measures are important indicators of how our business is performing, however, we may rely on different metrics in the future. We also utilize gross profit percentage as shown in the following section to monitor our most significant variable costs and to evaluate labor efficiency and success at passing increasing costs of materials to customers.

Net Revenue, Cost of Sales and Gross Profit
The components of gross profit were as follows (in millions):

| Three months ended September 30, |  | Nine months ended September 30,
| 2025 |  | Change |  | 2024 |  | 2025 |  | Change |  | 2024
Net revenue | $ | 778.2 |  |  | 2.3 | % |  | $ | 760.6 |  |  | $ | 2,223.3 |  |  | 1.5 | % |  | $ | 2,191.1 |
Cost of sales | 514.0 |  |  | 2.0 | % |  | 503.8 |  |  | 1,475.5 |  |  | 1.9 | % |  | 1,448.4 |
Gross profit | $ | 264.2 |  |  | 2.9 | % |  | $ | 256.8 |  |  | $ | 747.8 |  |  | 0.7 | % |  | $ | 742.7 |
Gross profit percentage | 34.0 | % |  |  |  | 33.8 | % |  | 33.6 | % |  |  |  | 33.9 | %

Net revenue increased during the three months ended September 30, 2025 over the same period in 2024 due to both organic growth and contributions from our recent acquisitions. Same branch sales from our single-family end market declined 1.9% while same branch sales from our multi-family end market remained resilient with a decrease of only 6.5%, far outpacing the 25.4% decline in national multi-family completions through the latest U.S. Census Bureau data available of August 2025. These markets combined for a residential same branch sales decline of 2.8% for the three months ended September 30, 2025 over the same period in 2024, driven primarily by a 4.8% same branch sales volume decline and selling price and product mix growth of 1.5%. Conversely, our commercial end market grew 11.7% on a same branch basis for the three months ended September 30, 2025 over the same period in 2024, resulting in a 0.4% increase in total same branch sales for the three months ended September 30, 2025 over the same period in 2024. Lastly, sales within our Distribution and Manufacturing businesses, including intercompany sales, increased 29.8% during the three months ended September 30, 2025 which aligns with our strategy to enhance our procurement efforts through vertical integration in select product and end markets.
During the nine months ended September 30, 2025, net revenue increased 1.5% over the same period in 2024 due to contributions from our recent acquisitions and sales growth from our commercial end market.
During the three months ended September 30, 2025, gross profit increased as a percentage of net revenue as compared to the same period in 2024 primarily due to customer and supplier mix, partially offset by increased insurance costs and additional vehicle depreciation expense. Gross profit decreased as a percentage of net revenue during the nine months ended September 30, 2025 compared to the same period in 2024 primarily due to higher insurance and vehicle costs. We will continue to work with our suppliers to lessen the impact on our margins and with our customers to offset further cost increases through selling price adjustments.
Operating Expenses
Operating expenses were as follows (in millions):

| Three months ended September 30, |  | Nine months ended September 30,
| 2025 |  | Change |  | 2024 |  | 2025 |  | Change |  | 2024
Selling | $ | 36.2 |  |  | 1.1 | % |  | $ | 35.8 |  |  | $ | 107.3 |  |  | 3.6 | % |  | $ | 103.6 |
Percentage of total net revenue | 4.7 | % |  |  |  | 4.7 | % |  | 4.8 | % |  |  |  | 4.7 | %
Administrative | $ | 111.1 |  |  | 1.7 | % |  | $ | 109.2 |  |  | $ | 332.6 |  |  | 4.4 | % |  | $ | 318.5 |

Percentage of total net revenue | — | % |  |  |  | — | % |  | — | % |  |  |  | 0.2 | %
Amortization | $ | 10.1 |  |  | (3.8) | % |  | $ | 10.5 |  |  | $ | 30.3 |  |  | (4.4) | % |  | $ | 31.7 |
Percentage of total net revenue | 1.3 | % |  |  |  | 1.4 | % |  | 1.4 | % |  |  |  | 1.4 | %

Selling
The dollar increase in selling expenses for the three and nine months ended September 30, 2025 compared to 2024 was primarily driven by an increase in selling compensation and increased credit loss expense on higher revenues. Selling expense as a percentage of sales increased during the nine months ended September 30, 2025 compared to 2024 due to higher compensation expense.
30

Administrative
The dollar increase in administrative expenses for the three and nine months ended September 30, 2025 compared to 2024 was primarily due to an increase in compensation, which was attributable to both acquisitions and wage inflation. Also, facility costs increased due to inflationary pressures and acquisitions factored into the overall increase in administrative operating expenses. Administrative expenses increased as a percentage of sales for the nine months ended September 30, 2025 compared to 2024 primarily due to wage inflationary pressures, while administrative expenses decreased as a percentage of sales for the three months ended September 30, 2025 primarily due to organizational optimization and lower transaction fees.
Amortization
Amortization expense for the three and nine months ended September 30, 2025 compared to 2024 decreased primarily due to the acquisition of fewer finite-lived intangible assets.
Other Expense, Net
Other expense, net was as follows (in millions):

| Three months ended September 30, |  | Nine months ended September 30,
| 2025 |  | Change |  | 2024 |  | 2025 |  | Change |  | 2024
Interest expense, net | $ | 6.9 |  |  | (10.4) | % |  | $ | 7.7 |  |  | $ | 23.5 |  |  | (15.5) | % |  | $ | 27.8 |
Other income | (0.4) |  |  | 33.3 | % |  | (0.3) |  |  | (0.9) |  |  | 12.5 | % |  | (0.8) |
Total other expense, net | $ | 6.5 |  |  |  |  | $ | 7.4 |  |  | $ | 22.6 |  |  |  |  | $ | 27.0 |

Interest expense, net decreased during the three and nine months ended September 30, 2025 compared to the same periods in 2024 due to decreased interest expense associated with prior year term loan repricing, partially offset by decreased interest income on money market accounts.
Income Tax Provision
Income tax provision and effective tax rates were as follows (in millions):

| Three months ended September 30, |  | Nine months ended September 30,
| 2025 |  | 2024 |  | 2025 |  | 2024
Income tax provision | $ | 25.9 |  |  | $ | 25.3 |  |  | $ | 66.2 |  |  | $ | 67.3 |
Effective tax rate | 25.8 | % |  | 26.9 | % |  | 26.0 | % |  | 26.2 | %

The effective tax rates for each of the three and nine months ended September 30, 2025 were based on an estimated annual effective tax rate and were favorably impacted by recognition of a windfall tax benefit from equity award vesting. The effective tax rates for the three and nine months ended September 30, 2024 were based on an estimated annual effective tax rate, and the rate for nine months ended September 30, 2024 was favorably impacted by recognition of a windfall tax benefit from equity vesting. We do not expect the enactment of the One Big Beautiful Bill Act to have a material impact to our 2025 effective tax rate.
Other Comprehensive Loss, Net of Tax
Other comprehensive loss, net of tax was as follows (in millions):

| Three months ended September 30, |  | Nine months ended September 30,
| 2025 |  | 2024 |  | 2025 |  | 2024
Net change on cash flow hedges, net of taxes | $ | (2.2) |  |  | $ | (10.6) |  |  | $ | (11.6) |  |  | $ | (5.9) |

During the three and nine months ended September 30, 2025, we recorded unrealized losses of $2.3 million and $12.6 million, net of taxes, on our cash flow hedges due to the market's expectations for lower interest rates in the future relative to our two forward interest rate swaps. During the three and nine months ended September 30, 2024, we recorded unrealized losses of $11.4 million and $8.3 million, respectively, net of taxes, on our cash flow hedges due to the changes in the market's expectations for future long-term interest rates.
31

During the three months ended September 30, 2025 and 2024, we amortized $0.1 million and $1.1 million, respectively, and during the nine months ended September 30, 2025 and 2024 we amortized $1.4 million and $3.3 million, respectively, of our remaining unrealized gains and losses, net, on our terminated cash flow hedges to interest expense, not including the offsetting tax effects of $21 thousand and $0.3 million for the three months ended September 30, 2025 and 2024, respectively, and $0.4 million and $0.9 million for the nine months ended September 30, 2025 and 2024, respectively.
KEY FACTORS AFFECTING OUR OPERATING RESULTS
Inflation, Housing Affordability and Interest Rates
Inflation that affected the economy as a whole in 2022 began moderating in 2023 as the Federal Reserve took actions to stabilize inflation by raising the federal funds rate multiple times through July 2023. These rate hikes indirectly affected the 30-year fixed rate mortgage average in the United States, resulting in some rates peaking above 7% in recent years. These rate-driven pressures have curtailed housing demand as mortgage financing affordability has been reduced. Inflation rates in 2025 have remained above the 2% stated target, however the Federal Reserve has signaled plans to potentially lower rates further during the remainder of 2025. While a more accommodating Federal Reserve monetary policy does not directly determine mortgage rates, the expected easing of rates will likely contribute to a downward trend in mortgage rates in the near term. We expect to be impacted by the current elevated rates for the remainder of 2025 and into 2026 but anticipate pressures to lessen over time if mortgage rates are further reduced in the coming months.
In addition, housing affordability is impacted by international trade as certain housing inputs are more reliant on imports than domestic production. While we purchase the large majority of the products we install and sell domestically, our business could be impacted if overall home affordability is further reduced by higher material prices due to increased tariffs.
Trends in the Construction Industry
Elevated home prices, high mortgage rates, recent economic uncertainty and rising new home inventory were the primary contributors to the decline in demand of new homes in 2025. Activity slowed in the residential homebuilding market as non-seasonally adjusted single-family starts, our largest end market, decreased 4.9% through August 2025 compared to the same period in 2024, per the latest available U.S. Census Bureau data. Employment remains stable and continues to support demand for residential new construction activity despite the affordability concerns and recent economic uncertainty. As a result, while we expect cyclicality to continue in the housing industry, we believe the long-term opportunities in our residential and commercial end markets are favorable. Our largest customers are publicly traded homebuilders, and these builders have been able to increase affordability by offering mortgage rate buydowns as incentives to their customers. Regarding the repair and remodel markets, many existing homeowners are locked into low interest mortgages and an aging housing stock exists in many areas of the United States, bolstering demand in this end market.
Cost and Availability of Materials
We typically purchase the materials we use in our business directly from manufacturers. The largest fiberglass manufacturers have cut production capacity during past business cycles which has caused periods of industry-wide supply allocations. While we are not currently experiencing material supply shortages, we could incur such shortages in the remainder of 2025 and beyond if these manufacturers reduce production this year. We also experience price increases from our suppliers from time to time, including multiple increases over the last four years caused by supply shortages and general economic inflationary pressures. We could be subject to increased material pricing on some of the materials we install and sell due to tariffs imposed on goods imported from certain foreign nations. The extent of these increases will depend on a variety of factors including the magnitude of each tariff, the extent our vendors pass on the tariffs they incur, and the number of countries subject to tariffs in the future. We have not experienced a material impact from tariffs to date in 2025. Increased market pricing, regardless of the catalyst, has and could continue to impact our results of operations in 2025, to the extent that price increases cannot be passed on to our customers. We may have more difficulty raising prices in 2025 if housing demand contracts further. We will continue to work with our customers to adjust selling prices to offset higher costs as they occur.
Cost of Labor
Our business is labor intensive and the majority of our employees work as installers on local construction sites. We expect to continue to spend more to hire, train and retain installers to support our business, as tight labor availability continues within the construction industry. Our workers’ compensation costs also continue to rise as we increase our coverage for additional personnel.
32

Our employee retention rates remained better than industry averages in the nine months ended September 30, 2025. We believe this is a result of our strong culture and the various programs meant to benefit our employees, including our financial wellness plan, emotional well-being coaching, longevity stock compensation plan and comprehensive benefit packages we offer. We also provide assistance from the Installed Building Products Foundation meant to benefit our employees, their families and their communities. While improved retention drives lower costs to recruit and train new employees, resulting in greater installer productivity, these improvements are somewhat offset by the additional costs of these incentives.
LIQUIDITY AND CAPITAL RESOURCES
Our capital resources primarily consist of cash from operations and borrowings under our various debt agreements and capital equipment leases and loans. As of September 30, 2025, we had cash and cash equivalents of $333.3 million as well as access to $250.0 million under our asset-based lending credit facility (as defined below), less $3.5 million of outstanding letters of credit, resulting in total liquidity of $579.8 million. Liquidity may also be limited in the future by certain cash collateral limitations under our asset-based credit facility (as defined below), depending on the status of our borrowing base availability.
Short-Term Material Cash Requirements
Our primary capital requirements are to fund working capital needs, operating expenses, acquisitions and capital expenditures, to meet debt and leasing principal and interest obligations and to make required income tax payments. We may also use our resources to fund our optional stock repurchase program and pay quarterly and annual dividends. We expect to spend cash and cash equivalents to acquire various companies with at least $100.0 million in aggregate net revenue each fiscal year. The amount of cash paid for an acquisition is dependent on various factors, including the size and determined value of the business being acquired.
We expect to meet our short-term liquidity requirements primarily through net cash flows from operations, our cash and cash equivalents on hand and borrowings from various lenders under equipment and loan agreements. Additional sources of funds, should we need them, include borrowing capacity under our asset-based lending credit facility (as defined below).
We believe that our cash flows from operations, combined with our current cash levels and available borrowing capacity, will be adequate to support our ongoing operations and to fund our business needs, commitments and contractual obligations for at least the next 12 months as evidenced by our net positive cash flows from operations for the nine months ended September 30, 2025. We believe that we have access to additional funds, if needed, through the capital markets to obtain further debt financing under the current market conditions, but we cannot guarantee that such financing will be available on favorable terms, or at all. In the short-term, we expect the seasonal trends we typically experience to return, including higher sales in the spring, summer and fall than in the winter. This could affect the timing of cash collections and payments during the rest of 2025.
Long-Term Material Cash Requirements
Beyond the next twelve months, our principal demands for funds will be to fund working capital needs and operating expenses, to meet principal and interest obligations on our long-term debts and finance leases as they become due or mature, and to make required income tax payments. Additional funds may be spent on acquisitions, stock repurchases, capital improvements and dividend payments, at our discretion.
On a long-term basis, we may refinance existing debt or obtain further debt financing to the extent that our sources of capital are insufficient to meet our operating needs and/or growth strategy.
In "Management's Discussion and Analysis of Financial Condition and Results of Operations" included in our 2024 Form 10-K, we disclosed that we had $1.1 billion aggregate long-term material cash requirements as of December 31, 2024. In addition to these commitments, we have various long-term commitments to purchase material with variable pricing. See Part I, Item 1. Financial Statements, Note 16, Commitments and Contingencies, for more information on these commitments. There were no other material changes to our cash requirements during the period covered by this Quarterly Report on Form 10-Q outside of the normal course of our business.
Sources and Uses of Cash and Related Trends
Working Capital
We carefully manage our working capital and operating expenses. As of September 30, 2025 and December 31, 2024, our working capital including cash and cash equivalents was $663.0 million and $695.9 million, respectively. The decrease in 2025
33

was primarily driven by other current assets decreasing $32.8 million, the majority of which was a result of the amortization of prepaid expenses including insurance. There was also a $6.9 million decrease in inventory levels that contributed to lower working capital. We continue to look for opportunities to reduce our working capital as a percentage of net revenue.
The following table summarizes our cash flow activity (in millions):

| Nine months ended September 30,
| 2025 |  | 2024
Net cash provided by operating activities | $ | 306.5 |  |  | $ | 265.2 |
Net cash used in investing activities | (80.4) |  |  | (94.4) |
Net cash used in financing activities | (220.4) |  |  | (151.1) |

Cash Flows from Operating Activities
Our primary source of cash provided by operations is revenues generated from installing or selling building products and the resulting operating income generated by these revenues. Operating income is adjusted for certain non-cash items, and our cash flows from operations can be impacted by the timing of our cash collections on sales and collection of retainage amounts.
Our primary uses of cash from operating activities include payments for installation materials, compensation costs, leases, income taxes and other general corporate expenditures included in net income.
Net cash provided by operating activities increased from 2024 to 2025 primarily due to higher non-cash adjustments, a decrease in other assets and lower inventory levels partially offset by a decrease in accounts payable and an increase in accounts receivable due to higher net revenue.
Cash Flows from Investing Activities
Sources of cash from investing activities consist primarily of proceeds from the sales of property and equipment, settlements with interest rate swap counterparties and, periodically, maturities from short term investments. Cash used in investing activities consists primarily of purchases of property and equipment, payments for acquisitions and, periodically, purchases of short term investments.
Net cash used in investing activities decreased from 2024 to 2025 primarily due to less spending on acquisitions of businesses and fewer purchases of property and equipment in 2025 compared to 2024, partially offset by additional purchases of insignificant bolt-on acquisitions during the nine months ended September 30, 2025.
Cash Flows from Financing Activities
Our sources of cash from financing activities consist of proceeds from the issuances of vehicle and equipment notes payable and, periodically, other sources of debt financing. Cash used in financing activities consists primarily of debt repayments, acquisition-related obligations, dividends and stock repurchases.
Net cash used in financing activities increased from 2024 to 2025 primarily due to higher amounts of capital returned to shareholders in connection with common stock repurchases and dividend payments during the nine months ended September 30, 2025. These increases were partially offset by greater net proceeds from vehicle and equipment notes. See Part I, Item 1. Financial Statements, Note 12, Stockholders' Equity, for more information on the dividends paid and stock repurchases.
Debt
5.75% Senior Notes due 2028
In September 2019, we issued $300.0 million in aggregate principal amount of 5.75% senior unsecured notes (the “Senior Notes”). The Senior Notes will mature on February 1, 2028 and interest is payable semi-annually in cash in arrears on February 1 and August 1, commencing on February 1, 2020. The net proceeds from the Senior Notes offering were $295.0 million after debt issuance costs.
The indenture covering the Senior Notes contains restrictive covenants that, among other things, limit the ability of the Company and certain of our subsidiaries (subject to certain exceptions) to: (i) incur additional debt and issue preferred stock;
34

(ii) pay dividends on, redeem or repurchase stock in an aggregate amount exceeding 2.0% of market capitalization per fiscal year, or in an aggregate amount exceeding certain applicable restricted payment baskets; (iii) prepay subordinated debt; (iv) create liens; (v) make specified types of investments; (vi) apply net proceeds from certain asset sales; (vii) engage in transactions with affiliates; (viii) merge, consolidate or sell substantially all of our assets; and (ix) pay dividends and make other distributions from subsidiaries.
Credit Facilities
Term Loan Facility
In March 2024, we entered into Amendment No. 3 to our Term Loan Credit Agreement ("Third Amendment"). The Third Amendment amended certain terms of the previous seven-year term loan facility with Royal Bank of Canada as the administrative agent and collateral agent thereunder under our credit agreement (the “Term Loan Agreement”), dated as of December 14, 2021 (as previously amended by the First Amendment thereto dated April 28, 2023 and the Second Amendment thereto dated August 14, 2023). The Third Amendment allowed for the issuance of a new term loan (the "Term Loan") in the amount of $500.0 million which will mature on March 28, 2031. Net proceeds of the Term Loan were used to refinance the remaining $490.0 million on our previous term loan, pay fees and increase working capital. In November 2024, we repriced our Term Loan by entering into Amendment No. 4 to our Term loan Credit Agreement ("Fourth Amendment"). The amended Term Loan now bears interest, at our option, at a rate equal to either: the adjusted Term SOFR plus 1.75% per annum, or an alternative base rate plus 0.75%.
The Term Loan amortizes in quarterly principal payments of $1.3 million, with any remaining unpaid balances due on the maturity date of March 28, 2031. As of September 30, 2025, we had $489.2 million, net of unamortized debt issuance costs, due on our Term Loan.
Subject to certain exceptions, the Term Loan will be subject to mandatory prepayments of (i) 100% of the net cash proceeds from issuances or incurrence of debt by the Company or any of its restricted subsidiaries (other than with respect to certain permitted indebtedness (excluding any refinancing indebtedness); (ii) 100% (with step-downs to 50% and 0% based on achievement of specified net leverage ratios) of the net cash proceeds from certain sales or dispositions of assets by the Company or any of its restricted subsidiaries in excess of a certain amount and subject to reinvestment provision and certain other exception; and (iii) 50% (with step-downs to 25% and 0% based upon achievement of specified net leverage ratios) of excess cash flow of the Company and its restricted subsidiaries in excess of $15.0 million, subject to certain exceptions and limitations.
Asset-based Lending Credit Agreement
In February 2022, we amended and extended the term of our asset-based lending credit agreement (the "ABL Credit Agreement"). The ABL Credit Agreement increased the commitment under the asset-based lending credit facility (the "ABL Revolver") to $250.0 million from $200.0 million and permits us to further increase the commitment amount up to $300.0 million. The amendment also extends the maturity date from September 26, 2024 to February 17, 2027. The ABL Revolver bears interest at either the base rate or the Secured Overnight Financing Rate ("Term SOFR"), at our election, plus a margin of 0.25% or 0.50% in the case of base rate loans or 1.25% or 1.50% for Term SOFR advances (in each case based on a measure of availability under the ABL Credit Agreement). The amendment also allows for modification of specified fees dependent upon achieving certain sustainability targets, in addition to making other modifications to the ABL Credit Agreement. Including outstanding letters of credit, our remaining availability under the ABL Revolver as of September 30, 2025 was $246.5 million.
The ABL Revolver provides incremental revolving credit facility commitments of up to $50.0 million. The terms and conditions of any incremental revolving credit facility commitments must be no more favorable than the terms of the ABL Revolver. The ABL Revolver also allows for the issuance of letters of credit of up to $100.0 million in aggregate and borrowing of swingline loans of up to $25.0 million in aggregate.
The ABL Credit Agreement contains a financial covenant requiring the satisfaction of a minimum fixed charge coverage ratio of 1.0x in the event that we do not meet a minimum measure of availability under the ABL Revolver. The ABL Credit Agreement and the Term Loan Agreement contain restrictive covenants that, among other things, limit the ability of the Company and certain of our subsidiaries (subject to certain exceptions) to: (i) incur additional debt and issue preferred stock; (ii) pay dividends on, redeem or repurchase stock in an aggregate amount exceeding the greater of 2.0% of market capitalization per fiscal year or certain applicable restricted payment basket amounts' (iii) prepay subordinated debt; (iv) create liens; (v) make specified types of investments; (vi) apply net proceeds from certain asset sales; (vii) engage in transactions with affiliates; (viii) merge, consolidate or sell substantially all of our assets; and (ix) pay dividends and make other distributions from subsidiaries.
35

At September 30, 2025, we were in compliance with all applicable covenants under the Term Loan Agreement, ABL Credit Agreement and the Senior Notes.
Derivative Instruments
As of September 30, 2025, we had three active interest rate swaps with maturity dates of December 31, 2025 and two forward interest rate swaps with maturity dates of December 14, 2028. When combined, these five swaps serve to hedge $400.0 million of the variable cash flows on our Term Loan through December 14, 2028. For further information about our interest rate swaps, see Part I, Item 1. Financial Statements, Note 11, Derivatives and Hedging Activities. The assets associated with the interest rate swaps are included in current assets and other non-current assets on the Consolidated Balance Sheets at their fair value amounts as described in Note 9, Fair Value Measurements.
Vehicle and Equipment Notes
We are party to a Master Loan and Security Agreement (“Master Loan and Security Agreement”), a Master Equipment Lease Agreement (“Master Equipment Agreement”) and one or more Master Loan Agreements (“Master Loan Agreements” and together with the Master Loan and Security Agreement and Master Equipment Agreement, the “Master Loan and Equipment Agreements”) with various lenders to provide financing for the purpose of purchasing or leasing vehicles and equipment used in the normal course of business. Vehicles and equipment purchased or leased under each financing arrangement serve as collateral for the note applicable to such financing arrangement. Regular payments are due under each note for a period of typically 60 consecutive months after the incurrence of the obligation.
Total outstanding loan balances relating to our Master Loan and Equipment Agreements were $92.0 million as of September 30, 2025 and $82.3 million as of December 31, 2024. Depreciation of assets held under these agreements is included within cost of sales on the Condensed Consolidated Statements of Operations and Comprehensive Income included herein.
Letters of Credit and Bonds
We may use performance bonds to ensure completion of our work on certain larger customer contracts that can span multiple accounting periods. Performance bonds are generally released as the contractual performance is completed. In addition, we occasionally use letters of credit and cash to secure our performance under our general liability, workers’ compensation and auto insurance programs. Permit and license bonds are typically issued for one year and are required by certain states and municipalities when we obtain licenses and permits to perform work in their jurisdictions.
The following table summarizes our outstanding bonds, letters of credit and cash-collateral (in millions):

| As of September 30, 2025
Performance bonds | $ | 143.9 |
Insurance letters of credit and cash collateral | 71.7 |
Permit and license bonds | 11.2 |
Total bonds and letters of credit | $ | 226.8 |

We have $65.3 million included in our insurance letters of credit in the above table that are unsecured and therefore do not reduce total liquidity.
Critical Accounting Policies and Estimates
Management’s discussion and analysis of our financial condition and results of operations is based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of our consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and related disclosure of contingent assets and liabilities. Certain accounting policies involve judgments and uncertainties to such an extent that there is a reasonable likelihood that materially different amounts could have been reported using different assumptions or under different conditions. We evaluate our estimates and assumptions on a regular basis. We base our estimates on historical experience and various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of our assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates and assumptions used in preparation of our consolidated financial statements. There have been no significant changes
36

to our critical accounting policies and estimates during the nine months ended September 30, 2025 from those disclosed in the “Management’s Discussion and Analysis of Financial Condition and Results of Operations” section of our 2024 Form 10-K.
Recent Accounting Pronouncements
For a description of recently issued and/or adopted accounting pronouncements, see Note 2, Significant Accounting Policies, to our audited consolidated financial statements included in our 2024 Form 10-K.
Forward-Looking Statements
This Quarterly Report on Form 10-Q contains forward-looking statements within the meaning of the federal securities laws, including with respect to the housing market and the commercial market, our operations, economic and industry conditions, our financial and business model, payment of dividends, the demand for our services and product offerings, trends in the commercial business, expansion of our national footprint and diversification, our ability to grow and strengthen our market position, our ability to pursue and integrate value-enhancing acquisitions, our ability to improve sales and profitability, our efforts to navigate the material pricing environment, our ability to increase selling prices, our material and labor costs, supply chain and material constraints and expectations for demand for our services and our earnings in 2025. Forward-looking statements may generally be identified by the use of words such as “anticipate,” “believe,” “estimate,” “project,” “predict,” “possible,” “forecast,” “may,” “could,” “would,” “should,” “expect,” “intends,” “plan,” and “will” or, in each case, their negative, or other variations or comparable terminology. These forward-looking statements include all matters that are not historical facts. By their nature, forward-looking statements involve risks and uncertainties because they relate to events and depend on circumstances that may or may not occur in the future. Any forward-looking statements that we make herein and in any future reports and statements are not guarantees of future performance, and actual results may differ materially from those expressed in or suggested by such forward-looking statements as a result of various factors, including, without limitation the general economic and industry conditions; increases in mortgage interest rates and rising home prices; inflation and interest rates; the material price and supply environment; increased tariffs; federal government shutdowns and uncertainty regarding the federal government’s changes in fiscal, trade, monetary or regulatory policy; the timing of increases in our selling prices; the risk that the Company may reduce, suspend or eliminate dividend payments in the future; and the factors discussed in the “Risk Factors” section of our 2024 Form 10-K, as the same may be updated from time to time in our subsequent filings with the SEC. In addition, any future declaration of dividends will be subject to the final determination of our Board of Directors. Any forward-looking statement made by the Company in this report speaks only as of the date hereof. New risks and uncertainties arise from time to time and it is impossible for the Company to predict these events or how they may affect it. The Company has no obligation, and does not intend, to update any forward-looking statements after the date hereof, except as required by federal securities laws.
Item 3. Quantitative and Qualitative Disclosures About Market Risk
We are exposed to market risks related to fluctuations in interest rates on our outstanding variable rate debt. As of September 30, 2025, we had $492.5 million outstanding on our Term Loan, gross of unamortized debt issuance costs, no outstanding borrowings on our ABL Revolver and no outstanding borrowings under finance leases subject to variable interest rates. As of September 30, 2025, we had three active and two forward interest rate swaps which, when combined, serve to hedge $400.0 million of the variable cash flows on our Term Loan through December 14, 2028. As a result, total variable rate debt of $92.5 million was exposed to market risks as of September 30, 2025. A hypothetical one percentage point increase (decrease) in interest rates on our variable rate debt would increase (decrease) our annual interest expense by approximately $0.9 million. Our Senior Notes accrue interest at a fixed rate of 5.75%.
For variable rate debt, interest rate changes generally do not affect the fair value of the debt instrument, but do impact future earnings and cash flows, assuming other factors are held constant. We have not entered into and currently do not hold derivatives for trading or speculative purposes.
Item 4. Controls and Procedures
Evaluation of Disclosure Controls and Procedures
We have evaluated the effectiveness of our disclosure controls and procedures as of the end of the period covered by this report with the participation of our Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”) as required by Exchange

Changes in Internal Control over Financial Reporting
There were no changes in our internal control over financial reporting during the three months ended September 30, 2025 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
