TOPBUILD CORP.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

​

1.  BASIS OF PRESENTATION

​

TopBuild is listed on the NYSE under the ticker symbol “BLD.” We report our business in two segments: Installation and Specialty Distribution.  Our Installation segment primarily installs insulation and other building products. Our Specialty Distribution segment primarily sells and distributes insulation and other building products. Our segments are based on our operating units, for which financial information is regularly evaluated by our chief operating decision maker.

​

We believe the accompanying unaudited condensed consolidated financial statements contain all adjustments, of a normal recurring nature, necessary to state fairly our financial position as of March 31, 2024, our results of operations and comprehensive income for the three months ended March 31, 2024 and 2023, and our cash flows for the three months ended March 31, 2024 and 2023. The condensed consolidated balance sheet at December 31, 2023 was derived from our audited financial statements, but does not include all disclosures required by GAAP.

​

These condensed consolidated financial statements and related notes should be read in conjunction with the audited Consolidated Financial Statements included in the Company’s Annual report for the year ended December 31, 2023, as filed with the SEC on February 28, 2024.

​

2.  ACCOUNTING POLICIES

​

Financial Statement Presentation.  Our condensed consolidated financial statements have been developed in conformity with GAAP, which requires management to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities and disclosures of contingent liabilities at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting periods. Actual results could differ materially from these estimates. All intercompany transactions between TopBuild entities have been eliminated.

​

Recently Adopted Accounting Pronouncements

​

In October 2021, the FASB issued ASU 2021-08, “Accounting for Contract Assets and Contract Liabilities from Contracts with Customers”. This standard improved the accounting for acquired revenue contracts with customers in a business combination by addressing diversity in practice and inconsistency related to recognition of an acquired contract liability, as well as payment terms and their effect on subsequent revenue recognized by the acquirer. This standard became effective for us on January 1, 2023, and did not have a material impact to our financial statements upon adoption.

​

Recently Issued Accounting Pronouncements Not Yet Adopted

​

In November 2023, the FASB issued ASU 2023-07, “Segment Reporting (Topic 280), Improvements to Reportable Segment Disclosures”.  This standard amends Topic 280 to require all entities to disclose, on an annual and interim basis, significant segment expenses and an amount for other segment items by reportable segment.  This standard is effective for fiscal years beginning after December 15, 2023, with early adoption permitted.  We do not anticipate that this standard will affect our consolidated results of operations, financial position or cash flows and we are assessing the impact of adoption in our disclosures to the consolidated financial statements.

​

In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740), Improvements to Income Tax Disclosures”.  This standard amends Topic 740 to require all entities to disclose specific categories in the rate reconciliation, income taxes paid and other income tax information.  This standard is effective for fiscal years beginning after December 15, 2024, with early adoption permitted and should be applied on a prospective basis.  We do not anticipate that this standard will affect our consolidated results of operations, financial position or cash flows and we are assessing the impact of its adoption in our disclosures to our consolidated financial statements.

​

The aggregate amount remaining on uncompleted performance obligations was $392.4 million as of March 31, 2024. We expect to satisfy the performance obligations and recognize revenue on substantially all of these uncompleted contracts over the next 18 months.

​

On certain of our long-term contracts, a percentage of the total project cost is withheld and not invoiced to the customer and collected until satisfactory completion of the customer’s project, typically within a year. This amount is referred to as retainage and is common practice in the construction industry. Retainage receivables are classified as a component of Receivables, net on our condensed consolidated balance sheets and were $82.2 million and $81.9 million as of March 31, 2024 and December 31, 2023, respectively.

4.  GOODWILL AND OTHER INTANGIBLES

​

We have two reporting units which are also our operating and reporting segments: Installation and Specialty Distribution.  Both reporting units contain goodwill.  Assets acquired and liabilities assumed are assigned to the applicable reporting unit based on whether the acquired assets and liabilities relate to the operations of such unit and determination of its fair value.  Goodwill assigned to the reporting unit is the excess of the fair value of the acquired business over the fair value of the individual assets acquired and liabilities assumed for the reporting unit.

​

In the fourth quarter of 2023, we performed an annual assessment on our goodwill resulting in no impairment and there were no indicators of impairment for the three months ended March 31, 2024.

​

Credit Agreement

On July 26, 2023, we entered into Amendment No. 4 to our Credit Agreement, which provided for a new $550.0 million Term Facility Two, the proceeds of which were intended to be used, in part, to finance the acquisition of SPI, including the payment of related fees and expenses.  Refer to Note 14 – Subsequent Events for details regarding the termination of our agreement to acquire SPI and Term Facility Two.

​

The following table outlines the key terms of the Credit Agreement (dollars in thousands):

​

​	​	​	​
Senior secured term loan facility	$	600,000	​
​	​	​	​
Revolving facility (a)	$	500,000	​
Sublimit for issuance of letters of credit under revolving facility	$	100,000	​
Sublimit for swingline loans under revolving facility	$	35,000	​
​	​	​	​
Interest rate as of March 31, 2024	​	6.43	%
Scheduled maturity date	​	10/7/2026	​

(a)	Use of the sublimits for the issuance of letters of credit and swingline loans reduces the availability under the revolving facility.

​

Interest expense on borrowings under the Credit Agreement is based on an applicable margin rate plus, at our option, either:  

​

●

A base rate determined by reference to the highest of either (i) the federal funds rate plus 0.50 percent, (ii) BofA’s “prime rate,” and (iii) the SOFR rate for U.S. dollar deposits with a term of one month, plus 1.00 percent (Term Facility One); or

●

A SOFR rate determined by reference to the costs of funds for deposits in U.S. dollars for the interest period relevant to such borrowings, subject to a floor of 0%.

​

The applicable margin rate is determined based on our Secured Leverage Ratio. In the case of base rate borrowings, the applicable margin rate ranges from 0.00 percent to 1.50 percent for Term Facility One and in the case of SOFR rate borrowings, the applicable margin ranges from 1.00 percent to 2.50 percent for Term Facility One. Borrowings under the Credit Agreement are prepayable at the Company’s option without premium or penalty. The Company is required to make prepayments with the net cash proceeds of certain asset sales and certain extraordinary receipts.

​

Revolving Facility

​

The Company has outstanding standby letters of credit that secure our financial obligations related to our workers’ compensation, general insurance, and auto liability programs. These standby letters of credit, as well as any outstanding amount borrowed under our revolving facility, reduce the availability under the revolving facility.

​

We are required to pay commitment fees to the Lenders in respect of any unutilized commitments. The commitment fees range from 0.15 percent to 0.275 percent per annum, depending on our Secured Leverage Ratio. We must also pay customary fees on outstanding letters of credit.

​

3.625% Senior Notes

The 3.625% Senior Notes are $400.0 million senior unsecured obligations and bear interest at 3.625% per year, payable semiannually in arrears on March 15 and September 15, beginning on September 15, 2021. The 3.625% Senior Notes mature on March 15, 2029, unless redeemed early or repurchased. If we undergo a change in control, we must make an offer to repurchase all of the 3.625% Senior Notes then outstanding at a repurchase price equal to 101% of their aggregate principal amount, plus accrued and unpaid interest (if any) to, but not including, the repurchase date. The Company may redeem the 3.625% Senior Notes, in whole or in part, at any time on or after March 15, 2024 at the redemption prices specified in the notes.

​

4.125% Senior Notes

​

The 4.125% Senior Notes are $500.0 million senior unsecured obligations and bear interest at 4.125% per year, payable semiannually in arrears on February 15 and August 15, beginning on August 15, 2022. The 4.125% Senior Notes mature on February 15, 2032, unless redeemed early or repurchased. If we undergo a change in control, we must make an offer to repurchase all of the 4.125% Senior Notes then outstanding at a repurchase price equal to 101% of their aggregate principal amount, plus accrued and unpaid interest (if any) to, but not including, the repurchase date. 

​

The Company may redeem the 4.125% Senior Notes, in whole or in part, at any time on or after October 15, 2026 at the redemption prices specified in the notes plus accrued and unpaid interest if redeemed during the 12 month period commencing on October 15 of the years set for: 2026 – 102.063%, 2027 – 101.375%, 2028 – 100.688%, 2029 and thereafter – 100.000%. The Company may also redeem a make-whole redemption of the 4.125% Senior Notes at any time prior to October 15, 2026 at the treasury rate plus 50 basis points. Additionally, the Company may redeem up to 40% of the aggregate principal amount of the 4.125% Senior Notes prior to October 15, 2024 with the net cash proceeds of certain sales of its capital stock at 104.125% of the principal amount of the notes, plus accrued and unpaid interest, if any, to the date of redemption only if, after the redemption, at least 60% of the aggregate principal amount of the notes originally issued remains outstanding.

​

Equipment Notes

​

We did not issue equipment notes during the three months ended March 31, 2024. The balance of equipment notes, which were issued for the purpose of financing vehicles and equipment, was $1.2 million as of March 31, 2024. The Company’s equipment notes each have a five year term maturing in 2024 and bear interest at fixed rates between 2.8% and 4.4%.

​

  Covenant Compliance

The indentures governing our 3.625% Senior Notes and our 4.125% Senior Notes (together, our “Senior Notes”) contain restrictive covenants that, among other things, generally limit the ability of the Company and certain of its subsidiaries (subject to certain exceptions) to (i) create liens, (ii) pay dividends, acquire shares of capital stock and make payments on subordinated debt, (iii) place limitations on distributions from certain subsidiaries, (iv) issue or sell the capital stock of certain subsidiaries, (v) sell assets, (vi) enter into transactions with affiliates, and (vii) effect mergers. The indentures provide for customary events of default which include (subject in certain cases to customary grace and cure periods), among others: nonpayment of principal or interest; breach of covenants or other agreements in the indenture; defaults in failure to pay certain other indebtedness; and certain events of bankruptcy or insolvency. Generally, if an event of default occurs and is continuing under the indenture, the trustee or the holders of at least 30% in aggregate principal amount of each of our Senior Notes then outstanding may declare the principal of, premium, if any, and accrued interest on the Senior Notes subject to such declaration immediately due and payable. The Senior Notes and related guarantees have not been registered under the Securities Act of 1933, and we are not required to register either the Senior Notes or the guarantees in the future.

​

The Credit Agreement contains certain covenants that limit, among other things, the ability of the Company to incur additional indebtedness or liens; to make certain investments or loans; to make certain restricted payments; to enter into consolidations, mergers, sales of material assets, and other fundamental changes; to transact with affiliates; to enter into agreements restricting the ability of subsidiaries to incur liens or pay dividends; or to make certain accounting changes.  The Credit Agreement contains customary affirmative covenants and events of default.

​

The Credit Agreement requires that we maintain a Net Leverage Ratio and minimum Interest Coverage Ratio throughout the term of the agreement. The following table outlines the key financial covenants effective for the period covered by this Quarterly Report:

​

​	​	​
​	​	As of March 31, 2024
Maximum Net Leverage Ratio	​	3.50:1.00
Minimum Interest Coverage Ratio	​	3.00:1.00

6. FAIR VALUE MEASUREMENTS

Fair Value on Recurring Basis

The carrying values of cash and cash equivalents, receivables, net, and accounts payable are considered to be representative of their respective fair values due to the short-term nature of these instruments. We measure our contingent consideration
liabilities related to business combinations at fair value.

​

Fair Value on Non-Recurring Basis

Fair value measurements were applied to our long-term debt portfolio. We believe the carrying value of our term loan and equipment notes approximate their fair market value primarily due to the fact that the non-performance risk of servicing our debt obligations, as reflected in our business and credit risk profile, has not materially changed since we assumed our debt obligations under the Credit Agreement. In addition, due to the floating-rate nature of our term loan, the market value is not subject to variability solely due to changes in the general level of interest rates as is the case with a fixed-rate debt obligation. Based on market trades of our 3.625% Senior Notes and our 4.125% Senior Notes close to March 31, 2024 (Level 1 fair value measurement), we estimate the fair value of each in the table below:  

​

​	​	​	​	​	​	​
​	​	As of March 31, 2024
​	​	​	Fair Value	​	​	Gross Carrying Value
3.625% Senior Notes	​	$	364,940	​	$	400,000
4.125% Senior Notes	​	$	445,000	​	$	500,000

8.  INCOME TAXES    

​

Our effective tax rates were 26.4 percent and 25.9 percent for the three months ended March 31, 2024 and March 31, 2023, respectively. The higher 2024 tax rate was primarily related to an increase in tax expense related to share-based compensation.

​

A tax expense of $2.0 million related to share-based compensation was recognized in our condensed consolidated statements of operations as a discrete item in income tax expense for the three months ended March 31, 2024.

9. NET INCOME PER SHARE

​

Basic net income per share is calculated by dividing net income by the number of weighted average shares outstanding during the period, without consideration for common stock equivalents. Diluted net income per share is calculated by adjusting the number of weighted average shares outstanding for the dilutive effect of common stock equivalents outstanding for the period, determined using the treasury stock method.

​

Basic and diluted net income per share were computed as follows:

11. BUSINESS COMBINATIONS

​

Acquiring businesses is a key part of our ongoing strategy to grow our company and expand our market share. Each acquisition has been accounted for as a business combination under ASC 805, “Business Combinations.” Acquisition related costs were $0.5 million and $1.7 million in the three months ended March 31, 2024 and 2023, respectively. Acquisition related costs are included in selling, general, and administrative expense in our condensed consolidated statements of operations.

​

On February 15, 2024, we acquired the assets of the residential and light commercial insulation business Brabble. This installation acquisition enhanced our presence in North Carolina. The purchase price of $5.4 million was funded by cash on hand and we recognized $3.0 million of goodwill in connection with this acquisition.

​

On March 1, 2024, we acquired the assets of the residential insulation business Morris Black. This installation acquisition enhanced our presence in the Pennsylvania market. The purchase price of $3.6 million was funded by cash on hand and we recognized $2.0 million of goodwill in connection with this acquisition.

​

On March 1, 2024, we acquired the assets of the customized insulation products and accessories business PCI. This specialty distribution acquisition has a national customer base focused on the domestic pest control industry.  The purchase price of $13.3 million was funded by cash on hand and we recognized $6.3 million of goodwill in connection with this acquisition.

​

The estimate of acquired customer relationships related to our 2024 acquisitions was $6.0 million and the weighted average useful life is 12 years.

​

As third-party or internal valuations are finalized, certain tax aspects of the foregoing transactions are completed, and customer post-closing reviews are concluded, adjustments may be made to the fair value of assets acquired, and in some cases total purchase price, through the end of each measurement period, generally one year following the applicable acquisition date.  

​

During the three months ended March 31, 2023, we acquired SRI and the purchase price of $45.3 was funded by cash on hand and we recognized goodwill of $23.1 million in connection with this acquisition.

​

Goodwill to be recognized in connection with acquisitions is attributable to the synergies expected to be realized and improvements in the businesses after the acquisitions. Primarily all of the $11.2 million and $23.1 million of goodwill recorded from acquisitions completed in the three months ended March 31, 2024 and 2023, respectively, is expected to be deductible for income tax purposes.

​

See Note 3 – Revenue Recognition for discussion of our deferred revenue balances. Accrued income taxes payable increased significantly compared to December 31, 2023 due to timing of tax payments, which typically occur later in the year.

​

13.  OTHER COMMITMENTS AND CONTINGENCIES

​

Litigation.  We are subject to certain claims, charges, litigation, and other proceedings in the ordinary course of our business, including those arising from or related to contractual matters, intellectual property, personal injury, environmental matters, product liability, product recalls, construction defects, insurance coverage, personnel and employment disputes, antitrust, and other matters, including class actions. We believe we have adequate defenses in these matters, and we do not believe that the ultimate outcome of these matters will have a material adverse effect on us.  However, there is no assurance that we will prevail in any of these pending matters, and we could in the future incur judgments, enter into settlements of claims, or revise our expectations regarding the outcome of these matters, which could materially impact our liquidity and our results of operations.

​

Other Matters.  We enter into contracts, which include customary indemnities that are standard for the industries in which we operate. Such indemnities include, among other things, claims against our builder customers for issues relating to our workmanship. We generally exclude from our contracts with builder customers indemnity relating to product quality and warranty claims, as we pass such claims directly to the manufacturers of the products we install or distribute. In conjunction with divestitures and other transactions, we occasionally provide customary indemnities relating to various items including, among others, the enforceability of trademarks, legal and environmental issues, and asset valuations. We evaluate the probability that we may incur liabilities under these customary indemnities and appropriately record an estimated liability when deemed probable.

​

We also maintain indemnification agreements with our directors and officers that may require us to indemnify them against liabilities that arise by reason of their status or service as directors or officers, except as prohibited by applicable law.

​

We occasionally use performance bonds to ensure completion of our work on certain larger customer contracts that can span multiple accounting periods. Performance bonds generally do not have stated expiration dates; rather, we are released from the bonds as the contractual performance is completed. We also have bonds outstanding for license and insurance.

14.  SUBSEQUENT EVENTS

​

On April 22, 2024, we agreed to a mutual termination of our previous agreement to acquire SPI, originally announced on July 27, 2023. We withdrew our Hart-Scott Rodino filings and were required to pay a termination fee of $23.0 million to the seller under the terms of the purchase agreement. In connection with the termination of the SPI acquisition, the Company terminated the commitments with respect to its undrawn Term Facility Two which was provided pursuant to Amendment No. 4. All other terms of the Company’s Credit Agreement, as amended, remain in full force and effect.

​

On May 3, 2024, our Board authorized the 2024 Repurchase Program, pursuant to which the Company may purchase up to $1.0 billion of our common stock.  Share repurchases may be executed through various means including open market purchases, privately negotiated transactions, accelerated share repurchase transactions, or other available means.  The 2024 Repurchase Program does not obligate the Company to purchase any shares and has no expiration date.  Authorization for the 2024 Repurchase Program may be terminated, increased, or decreased by the Board at its discretion at any time.

​

On May 3, 2024, we entered into an agreement to acquire the assets of the residential insulation business Insulation Works, Inc., which is expected to close in mid-May 2024. This installation acquisition will enhance our presence in the Arkansas market and extend our expertise to the agricultural market. The purchase price of approximately $25.2 million is expected to be funded by cash on hand. This acquisition will be accounted for as a business combination under ASC 805, “Business Combinations.”

Item 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

OVERVIEW

​

TopBuild, headquartered in Daytona Beach, Florida, is a leading installer and specialty distributor of insulation and other building material products to the construction industry in the United States and Canada.

​

We operate in two segments: Installation and Specialty Distribution. Our Installation segment installs insulation and other building products nationwide. As of March 31, 2024, we had approximately 240 Installation branches located across the United States. We install various insulation applications, including fiberglass batts and rolls, blown-in loose fill fiberglass, polyurethane spray foam, and blown-in loose fill cellulose. Additionally, we install other building products including glass and windows, rain gutters, garage doors, closet shelving, and fireplaces, among other items. We handle every stage of the installation process, including material procurement supplied by leading manufacturers, project scheduling and logistics, multi-phase professional installation, and installation quality assurance.

​

Our Specialty Distribution segment distributes building and mechanical insulation, insulation accessories, rain gutters, and other building product materials for the residential and commercial/industrial end markets. As of March 31, 2024, we had approximately 150 distribution centers located across the United States and 18 distribution centers in Canada. Our Specialty Distribution customer base consists of thousands of insulation contractors of all sizes serving a wide variety of residential and commercial/industrial industries, gutter contractors, weatherization contractors, other contractors, dealers, metal building erectors, and modular home builders.

​

We believe that having both Installation and Specialty Distribution provides us with several distinct competitive advantages.  First, the combined buying power of our two business segments, along with our scale, strengthens our ties to the major manufacturers of insulation and other building material products. This helps to ensure we are buying competitively and ensures the availability of supply to our local branches and distribution centers.  The overall effect is driving efficiencies through our supply chain. Second, being a leader in both installation and specialty distribution allows us to reach a broader set of builders and contractors more effectively, regardless of their size or geographic location in the U.S. and Canada, and leverage housing and commercial/industrial construction growth wherever it occurs. Third, during housing industry downturns, many insulation contractors who buy directly from manufacturers during industry peaks return to purchasing through specialty distributors. As a result, this helps to reduce our exposure to cyclical swings in our business.

​

For additional details pertaining to our operating results by segment, see Note 7 – Segment Information to our unaudited condensed consolidated financial statements contained in Part I, Item 1 of this Quarterly Report. For additional details regarding our strategy, material trends in our business and seasonality, please refer to Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Annual Report for the year ended December 31, 2023, as filed with the SEC on February 28, 2024.

The following discussion and analysis contains forward-looking statements and should be read in conjunction with the unaudited condensed consolidated financial statements, the notes thereto, and the section entitled “Forward-Looking Statements” included in this Quarterly Report.

​

Sales and Operations

​

Net sales increased 1.1% for the three months ended March 31, 2024, from the comparable period of 2023. The increase was primarily driven by a 2.3% increase in sales from acquisitions and a 1.3% impact from higher selling prices, partially offset by a 2.0% decline in sales volume and a decline of 0.5% driven by the disposition of a non-core business.

 

Gross profit margins were 30.3% and 29.3% for the three months ended March 31, 2024 and 2023, respectively. Gross profit margin improved primarily due to productivity initiatives and higher selling prices.

​

Selling, general, and administrative expenses as a percentage of sales were 13.5% for the three months ended March 31, 2024 and 2023, respectively. Selling, general, and administrative expenses were relatively flat to the prior year period.

​

Operating margins were 16.8% and 15.8% for the three months ended March 31, 2024 and 2023, respectively. The increase in operating margins was due to productivity initiatives and higher selling prices, partially offset by higher material costs and lower sales volume in our Specialty Distribution segment.

​

Operating margins

​

Operating margins in our Installation segment were 19.6% and 19.1% for the three months ended March 31, 2024 and 2023, respectively. The increase in operating margin was driven by productivity initiatives and higher selling prices which were partially offset by higher material costs.

OTHER ITEMS

​

Other expense, net

​

Other expense, net, decreased to $7.5 million for the three months ended March 31, 2024 from $16.1 million in the three months ended March 31, 2023. The decrease was driven by $9.0 million higher interest income due to increased cash balances and higher deposit rates compared to the three months ended March 31, 2023. Interest expense increased by $0.8 million for the three months ended March 31, 2024 due to higher interest rates on borrowings under the Credit Agreement compared to the same period in 2023.

​

Income tax expense

​

Income tax expense was $54.6 million, an effective tax rate of 26.4 percent, for the three months ended March 31, 2024, compared to $47.4 million, an effective tax rate of 25.9 percent, for the comparable period in 2023. The tax rate for the three months ended March 31, 2024, was higher primarily related to an increase in tax expense related to share-based compensation.

​

Net cash flows provided by operating activities increased $9.0 million for the three months ended March 31, 2024, as compared to the prior year period primarily due to the increase of net income of $16.5 million compared with the prior year period.

Net cash used in investing activities was $40.5 million for the three months ended March 31, 2024, primarily composed of $22.2 million for our acquisitions and $19.9 million for purchases of property and equipment, mainly vehicles, partially offset by $1.6 million proceeds received from the sale of assets. Net cash used in investing activities was $61.0 million for the three months ended March 31, 2023, primarily composed of $45.8 million for the acquisition of SRI and $15.6 million for purchases of property and equipment, mainly vehicles and machinery & equipment.

Net cash used in financing activities was $17.1 million for the three months ended March 31, 2024.  During the three months ended March 31, 2024, we used $12.1 million for debt repayments and incurred $5.0 million net cash outflow related to exercise of share-based incentive awards and stock options. Net cash used in financing activities was $15.1 million for the three months ended March 31, 2023. During the three months ended March 31, 2023, we used $9.7 million for debt repayments, and $5.3 million net activity related to exercise of share-based incentive awards and stock options.

We have access to liquidity through our cash from operations and available borrowing capacity under our Credit Agreement, which provides for borrowing and/or standby letter of credit issuances of up to $500 million under the Revolving Facility. Additional information regarding our outstanding debt and borrowing capacity is incorporated by reference from Note 5 – Long-term Debt to our unaudited condensed consolidated financial statements contained in Part 1, Item 1 of this Quarterly Report.

(a)

Our cash and cash equivalents consist of AAA-rated money market funds as well as cash held in our demand deposit accounts.

​

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 known contractual obligations including funding our debt service requirements, capital expenditures, lease obligations and working capital needs for at least the next twelve months. We also have adequate liquidity to maintain off-balance sheet arrangements for short-term leases, letters of credit, and performance and license bonds. Information regarding our outstanding bonds as of March 31, 2024, is incorporated by reference from Note 13 – Other Commitments and Contingencies to our unaudited condensed consolidated financial statements contained in Part I, Item 1 of this Quarterly Report.

OUTLOOK

Residential New Construction

Home builders continue to report improving demand resulting in single-family housing starts that improved in the first quarter in comparison to the prior year.  Multifamily construction activity also remains strong but starts have slowed, in comparison to the prior year.  While there is a strong backlog of multi-family units that need to be completed, we do expect multifamily activity to decline as we move towards 2025. Single-family housing is a larger proportion of the overall housing market as well as a larger proportion of our market share. Overall, despite uncertainty around the economy and the impact of higher interest rates, we remain optimistic about the long-term fundamentals of the U.S. housing market, supported by a limited supply of both new and existing homes, favorable demographic trends, and increasing household formations. 

​

Commercial and Industrial Construction

Our commercial backlog is strong, and our bidding activity is active, both of which continue to support our optimistic view of commercial/industrial sales at our Installation and Specialty Distribution segments.  There are many major projects being planned across several different industries fueling demand. In addition, maintenance and repair work on industrial sites will serve as a continued driver for our Specialty Distribution business.

​

OFF-BALANCE SHEET ARRANGEMENTS

​

We had no material off-balance sheet arrangements during the three months ended March 31, 2024, other than short-term leases, letters of credit, and performance and license bonds, which have been disclosed in Part 1, Item 1 of this Quarterly report.

​

CONTRACTUAL OBLIGATIONS

​

There have been no material changes to our contractual obligations from those previously disclosed in our Annual Report for the year ended December 31, 2023, as filed with the SEC on February 28, 2024.

​

​

CRITICAL ACCOUNTING POLICIES

​

We prepare our condensed consolidated financial statements in conformity with GAAP. The preparation of these financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities, at the date of the financial statements, and the reported amounts of sales and expenses during the reporting period. Actual results could differ from those estimates. Our critical accounting policies have not changed from those previously reported in our Annual Report for the year ended December 31, 2023, as filed with the SEC on February 28, 2024.

​

APPLICATION OF NEW ACCOUNTING STANDARDS

​

Information regarding application of new accounting standards is incorporated by reference from Note 2 – Accounting Policies to our unaudited condensed consolidated financial statements contained in Part I, Item 1 of this Quarterly Report.

​

FORWARD-LOOKING STATEMENTS

​

Statements contained in this report that reflect our views about future periods, including our future plans and performance, constitute “forward-looking statements” under the Private Securities Litigation Reform Act of 1995. Forward-looking statements can be identified by words such as “will,” “would,” “should,” “anticipate,” “expect,” “believe,” “designed,” “plan,” “may,” “project,” “estimate”  or “intend,” the negative of these terms, and similar references to future periods.  These views involve risks and uncertainties that are difficult to predict and, accordingly, our actual results may differ materially from the results discussed in our forward-looking statements. We caution you against unduly relying on any of these forward-looking statements. Our future performance may be affected by the duration and impact of negative macro-economic impacts on the United States economy, specifically with respect to residential, commercial/industrial construction, our ability to collect our receivables from our customers, our reliance on residential new construction, residential repair/remodel, and commercial/industrial construction; our reliance on third-party suppliers and manufacturers; our ability to attract, develop, and retain talented personnel and our sales and labor force; our ability to maintain consistent practices across our locations; our ability to maintain our competitive position; and our ability to realize the expected benefits of our acquisitions. We discuss the material risks we face under the caption entitled “Risk Factors” in our Annual Report for the year ended December 31, 2023, as filed with the SEC on February 28, 2024, as well as under the caption entitled “Risk Factors” in subsequent reports that we file with the SEC. Our forward-looking statements in this filing speak only as of the date of this filing. Factors or events that could cause our actual results to differ may emerge from time to time and it is not possible for us to predict all of them.  Unless required by law, we undertake no obligation to update publicly any forward-looking statements as a result of new information, future events, or otherwise.

​

Item 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

​

Interest Rate Risk

​

We have a Term Loan outstanding with a principal balance of $521.3 million and a revolving facility with an aggregate borrowing capacity of $500.0 million. We also have outstanding 3.625% Senior Notes with an aggregate principal balance of $400.0 million and 4.125% Senior Notes with an aggregate principal balance of $500.0 million. The 3.625% Senior Notes and 4.125% Senior Notes bear a fixed rate of interest and therefore are excluded from the calculation below as they are not subject to fluctuations in interest rates.

​

Interest payable on both the aggregate Term Loan and Revolving Facility is based on a variable interest rate.  As a result, we are exposed to market risks related to fluctuations in interest rates on this outstanding indebtedness. As of March 31, 2024, the applicable interest rate as of such date was 6.43%. Based on our outstanding borrowings as of March 31, 2024, a 100-basis point increase in the interest rate would result in a $5.0 million increase in our annualized interest expense. There was no outstanding balance under the Revolving Facility as of March 31, 2024.

​

Evaluation of Disclosure Controls and Procedures

 

As of the end of the period covered by this Quarterly Report, we carried out an evaluation, under the supervision and with the participation of our principal executive officer and principal financial officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act). Based on this evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective as of March 31, 2024.

​

Changes in Internal Control over Financial Reporting

 

There was no change in the Company’s internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) in the most recent fiscal quarter ended March 31, 2024, that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

Basis of Presentation
Basis of Presentation	1.  BASIS OF PRESENTATION ​ TopBuild is listed on the NYSE under the ticker symbol “BLD.” We report our business in two segments: Installation and Specialty Distribution.  Our Installation segment primarily installs insulation and other building products. Our Specialty Distribution segment primarily sells and distributes insulation and other building products. Our segments are based on our operating units, for which financial information is regularly evaluated by our chief operating decision maker. ​ We believe the accompanying unaudited condensed consolidated financial statements contain all adjustments, of a normal recurring nature, necessary to state fairly our financial position as of March 31, 2024, our results of operations and comprehensive income for the three months ended March 31, 2024 and 2023, and our cash flows for the three months ended March 31, 2024 and 2023. The condensed consolidated balance sheet at December 31, 2023 was derived from our audited financial statements, but does not include all disclosures required by GAAP. ​ These condensed consolidated financial statements and related notes should be read in conjunction with the audited Consolidated Financial Statements included in the Company’s Annual report for the year ended December 31, 2023, as filed with the SEC on February 28, 2024. ​

Accounting Policies
Accounting Policies	2.  ACCOUNTING POLICIES ​ Financial Statement Presentation.  Our condensed consolidated financial statements have been developed in conformity with GAAP, which requires management to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities and disclosures of contingent liabilities at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting periods. Actual results could differ materially from these estimates. All intercompany transactions between TopBuild entities have been eliminated. ​ Recently Adopted Accounting Pronouncements ​ In October 2021, the FASB issued ASU 2021-08, “Accounting for Contract Assets and Contract Liabilities from Contracts with Customers”. This standard improved the accounting for acquired revenue contracts with customers in a business combination by addressing diversity in practice and inconsistency related to recognition of an acquired contract liability, as well as payment terms and their effect on subsequent revenue recognized by the acquirer. This standard became effective for us on January 1, 2023, and did not have a material impact to our financial statements upon adoption. ​ Recently Issued Accounting Pronouncements Not Yet Adopted ​ In November 2023, the FASB issued ASU 2023-07, “Segment Reporting (Topic 280), Improvements to Reportable Segment Disclosures”.  This standard amends Topic 280 to require all entities to disclose, on an annual and interim basis, significant segment expenses and an amount for other segment items by reportable segment.  This standard is effective for fiscal years beginning after December 15, 2023, with early adoption permitted.  We do not anticipate that this standard will affect our consolidated results of operations, financial position or cash flows and we are assessing the impact of adoption in our disclosures to the consolidated financial statements. ​ In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740), Improvements to Income Tax Disclosures”.  This standard amends Topic 740 to require all entities to disclose specific categories in the rate reconciliation, income taxes paid and other income tax information.  This standard is effective for fiscal years beginning after December 15, 2024, with early adoption permitted and should be applied on a prospective basis.  We do not anticipate that this standard will affect our consolidated results of operations, financial position or cash flows and we are assessing the impact of its adoption in our disclosures to our consolidated financial statements. ​

Goodwill and Other Intangibles	4.  GOODWILL AND OTHER INTANGIBLES ​ We have two reporting units which are also our operating and reporting segments: Installation and Specialty Distribution.  Both reporting units contain goodwill.  Assets acquired and liabilities assumed are assigned to the applicable reporting unit based on whether the acquired assets and liabilities relate to the operations of such unit and determination of its fair value.  Goodwill assigned to the reporting unit is the excess of the fair value of the acquired business over the fair value of the individual assets acquired and liabilities assumed for the reporting unit. ​ In the fourth quarter of 2023, we performed an annual assessment on our goodwill resulting in no impairment and there were no indicators of impairment for the three months ended March 31, 2024. ​ Changes in the carrying amount of goodwill for the three months ended March 31, 2024, by segment, were as follows, in thousands: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​      ​ ​      ​      ​ ​ ​ ​         Accumulated         ​ ​ ​ ​ Gross Goodwill ​ ​ ​ FX Translation ​ Gross Goodwill ​ Impairment ​ Net Goodwill ​ ​ December 31, 2023 ​ Additions ​ Adjustment ​ March 31, 2024 ​ Losses ​ March 31, 2024 Goodwill, by segment: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Installation ​ $ 1,901,160 ​ $ 4,916 ​ $ - ​ $ 1,906,076 ​ $ (762,021) ​ $ 1,144,055 Specialty Distribution ​   903,429 ​   6,261 ​ ​ (1,426) ​   908,264 ​   - ​   908,264 Total goodwill ​ $ 2,804,589 ​ $ 11,177 ​ $ (1,426) ​ $ 2,814,340 ​ $ (762,021) ​ $ 2,052,319 ​ See Note 11 – Business Combinations for goodwill recognized on acquisitions that occurred during the three months ended March 31, 2024. ​ Other intangible assets, net includes customer relationships, non-compete agreements, and trademarks / trade names.

In the case of base rate borrowings, the applicable margin rate ranges from 0.00 percent to 1.50 percent for Term Facility One and in the case of SOFR rate borrowings, the applicable margin ranges from 1.00 percent to 2.50 percent for Term Facility One. Borrowings under the Credit Agreement are prepayable at the Company’s option without premium or penalty. The Company is required to make prepayments with the net cash proceeds of certain asset sales and certain extraordinary receipts. ​ Revolving Facility ​ The Company has outstanding standby letters of credit that secure our financial obligations related to our workers’ compensation, general insurance, and auto liability programs. These standby letters of credit, as well as any outstanding amount borrowed under our revolving facility, reduce the availability under the revolving facility.   ​ The following table summarizes our availability under the revolving facility, in thousands: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ As of ​ ​ March 31, 2024      December 31, 2023 Revolving facility ​ $ 500,000 ​ $ 500,000 Less: standby letters of credit ​ ​ (63,770) ​ ​ (63,770) Availability under revolving facility ​ $ 436,230 ​ $ 436,230 ​ We are required to pay commitment fees to the Lenders in respect of any unutilized commitments. The commitment fees range from 0.15 percent to 0.275 percent per annum, depending on our Secured Leverage Ratio. We must also pay customary fees on outstanding letters of credit. ​ 3.625% Senior Notes The 3.625% Senior Notes are $400.0 million senior unsecured obligations and bear interest at 3.625% per year, payable semiannually in arrears on March 15 and September 15, beginning on September 15, 2021. The 3.625% Senior Notes mature on March 15, 2029, unless redeemed early or repurchased. If we undergo a change in control, we must make an offer to repurchase all of the 3.625% Senior Notes then outstanding at a repurchase price equal to 101% of their aggregate principal amount, plus accrued and unpaid interest (if any) to, but not including, the repurchase date. The Company may redeem the 3.625% Senior Notes, in whole or in part, at any time on or after March 15, 2024 at the redemption prices specified in the notes. ​ 4.125% Senior Notes ​ The 4.125% Senior Notes are $500.0 million senior unsecured obligations and bear interest at 4.125% per year, payable semiannually in arrears on February 15 and August 15, beginning on August 15, 2022. The 4.125% Senior Notes mature on February 15, 2032, unless redeemed early or repurchased. If we undergo a change in control, we must make an offer to repurchase all of the 4.125% Senior Notes then outstanding at a repurchase price equal to 101% of their aggregate principal amount, plus accrued and unpaid interest (if any) to, but not including, the repurchase date.  ​ The Company may redeem the 4.125% Senior Notes, in whole or in part, at any time on or after October 15, 2026 at the redemption prices specified in the notes plus accrued and unpaid interest if redeemed during the 12 month period commencing on October 15 of the years set for: 2026 – 102.063%, 2027 – 101.375%, 2028 – 100.688%, 2029 and thereafter – 100.000%. The Company may also redeem a make-whole redemption of the 4.125% Senior Notes at any time prior to October 15, 2026 at the treasury rate plus 50 basis points. Additionally, the Company may redeem up to 40% of the aggregate principal amount of the 4.125% Senior Notes prior to October 15, 2024 with the net cash proceeds of certain sales of its capital stock at 104.125% of the principal amount of the notes, plus accrued and unpaid interest, if any, to the date of redemption only if, after the redemption, at least 60% of the aggregate principal amount of the notes originally issued remains outstanding. ​ Equipment Notes ​ We did not issue equipment notes during the three months ended March 31, 2024. The balance of equipment notes, which were issued for the purpose of financing vehicles and equipment, was $1.2 million as of March 31, 2024. The Company’s equipment notes each have a five year term maturing in 2024 and bear interest at fixed rates between 2.8% and 4.4%. ​   Covenant Compliance The indentures governing our 3.625% Senior Notes and our 4.125% Senior Notes (together, our “Senior Notes”) contain restrictive covenants that, among other things, generally limit the ability of the Company and certain of its subsidiaries (subject to certain exceptions) to (i) create liens, (ii) pay dividends, acquire shares of capital stock and make payments on subordinated debt, (iii) place limitations on distributions from certain subsidiaries, (iv) issue or sell the capital stock of certain subsidiaries, (v) sell assets, (vi) enter into transactions with affiliates, and (vii) effect mergers. The indentures provide for customary events of default which include (subject in certain cases to customary grace and cure periods), among others: nonpayment of principal or interest; breach of covenants or other agreements in the indenture; defaults in failure to pay certain other indebtedness; and certain events of bankruptcy or insolvency. Generally, if an event of default occurs and is continuing under the indenture, the trustee or the holders of at least 30% in aggregate principal amount of each of our Senior Notes then outstanding may declare the principal of, premium, if any, and accrued interest on the Senior Notes subject to such declaration immediately due and payable. The Senior Notes and related guarantees have not been registered under the Securities Act of 1933, and we are not required to register either the Senior Notes or the guarantees in the future. ​ The Credit Agreement contains certain covenants that limit, among other things, the ability of the Company to incur additional indebtedness or liens; to make certain investments or loans; to make certain restricted payments; to enter into consolidations, mergers, sales of material assets, and other fundamental changes; to transact with affiliates; to enter into agreements restricting the ability of subsidiaries to incur liens or pay dividends; or to make certain accounting changes.  The Credit Agreement contains customary affirmative covenants and events of default. ​ The Credit Agreement requires that we maintain a Net Leverage Ratio and minimum Interest Coverage Ratio throughout the term of the agreement. The following table outlines the key financial covenants effective for the period covered by this Quarterly Report: ​ ​ ​ ​ ​ ​ As of March 31, 2024 Maximum Net Leverage Ratio ​ 3.50:1.00 Minimum Interest Coverage Ratio ​ 3.00:1.00 Compliance as of period end ​ In Compliance ​

Fair Value Measurements
Fair Value Measurements	6. FAIR VALUE MEASUREMENTS Fair Value on Recurring Basis The carrying values of cash and cash equivalents, receivables, net, and accounts payable are considered to be representative of their respective fair values due to the short-term nature of these instruments. We measure our contingent consideration liabilities related to business combinations at fair value. ​ Fair Value on Non-Recurring Basis Fair value measurements were applied to our long-term debt portfolio. We believe the carrying value of our term loan and equipment notes approximate their fair market value primarily due to the fact that the non-performance risk of servicing our debt obligations, as reflected in our business and credit risk profile, has not materially changed since we assumed our debt obligations under the Credit Agreement. In addition, due to the floating-rate nature of our term loan, the market value is not subject to variability solely due to changes in the general level of interest rates as is the case with a fixed-rate debt obligation. Based on market trades of our 3.625% Senior Notes and our 4.125% Senior Notes close to March 31, 2024 (Level 1 fair value measurement), we estimate the fair value of each in the table below:   ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ As of March 31, 2024 ​ ​ ​ Fair Value ​ ​ Gross Carrying Value 3.625% Senior Notes ​ $ 364,940 ​ $ 400,000 4.125% Senior Notes ​ $ 445,000 ​ $ 500,000 ​

Business Combinations	11. BUSINESS COMBINATIONS ​ Acquiring businesses is a key part of our ongoing strategy to grow our company and expand our market share. Each acquisition has been accounted for as a business combination under ASC 805, “Business Combinations.” Acquisition related costs were $0.5 million and $1.7 million in the three months ended March 31, 2024 and 2023, respectively. Acquisition related costs are included in selling, general, and administrative expense in our condensed consolidated statements of operations. ​ On February 15, 2024, we acquired the assets of the residential and light commercial insulation business Brabble. This installation acquisition enhanced our presence in North Carolina. The purchase price of $5.4 million was funded by cash on hand and we recognized $3.0 million of goodwill in connection with this acquisition. ​ On March 1, 2024, we acquired the assets of the residential insulation business Morris Black. This installation acquisition enhanced our presence in the Pennsylvania market. The purchase price of $3.6 million was funded by cash on hand and we recognized $2.0 million of goodwill in connection with this acquisition. ​ On March 1, 2024, we acquired the assets of the customized insulation products and accessories business PCI. This specialty distribution acquisition has a national customer base focused on the domestic pest control industry.  The purchase price of $13.3 million was funded by cash on hand and we recognized $6.3 million of goodwill in connection with this acquisition. ​ The estimate of acquired customer relationships related to our 2024 acquisitions was $6.0 million and the weighted average useful life is 12 years. ​ As third-party or internal valuations are finalized, certain tax aspects of the foregoing transactions are completed, and customer post-closing reviews are concluded, adjustments may be made to the fair value of assets acquired, and in some cases total purchase price, through the end of each measurement period, generally one year following the applicable acquisition date.   ​ During the three months ended March 31, 2023, we acquired SRI and the purchase price of $45.3 was funded by cash on hand and we recognized goodwill of $23.1 million in connection with this acquisition. ​ Goodwill to be recognized in connection with acquisitions is attributable to the synergies expected to be realized and improvements in the businesses after the acquisitions. Primarily all of the $11.2 million and $23.1 million of goodwill recorded from acquisitions completed in the three months ended March 31, 2024 and 2023, respectively, is expected to be deductible for income tax purposes.

We believe we have adequate defenses in these matters, and we do not believe that the ultimate outcome of these matters will have a material adverse effect on us.  However, there is no assurance that we will prevail in any of these pending matters, and we could in the future incur judgments, enter into settlements of claims, or revise our expectations regarding the outcome of these matters, which could materially impact our liquidity and our results of operations. ​ Other Matters.  We enter into contracts, which include customary indemnities that are standard for the industries in which we operate. Such indemnities include, among other things, claims against our builder customers for issues relating to our workmanship. We generally exclude from our contracts with builder customers indemnity relating to product quality and warranty claims, as we pass such claims directly to the manufacturers of the products we install or distribute. In conjunction with divestitures and other transactions, we occasionally provide customary indemnities relating to various items including, among others, the enforceability of trademarks, legal and environmental issues, and asset valuations. We evaluate the probability that we may incur liabilities under these customary indemnities and appropriately record an estimated liability when deemed probable. ​ We also maintain indemnification agreements with our directors and officers that may require us to indemnify them against liabilities that arise by reason of their status or service as directors or officers, except as prohibited by applicable law. ​ We occasionally use performance bonds to ensure completion of our work on certain larger customer contracts that can span multiple accounting periods. Performance bonds generally do not have stated expiration dates; rather, we are released from the bonds as the contractual performance is completed. We also have bonds outstanding for license and insurance. ​ The following table summarizes our outstanding performance, licensing, insurance, and other bonds, in thousands: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ As of ​ ​ March 31, 2024 ​ December 31, 2023 Outstanding bonds: ​ ​ ​ ​ ​ ​ Performance bonds ​ $ 141,380 ​ $ 145,982 Licensing, insurance, and other bonds ​ ​ 27,979 ​ ​ 27,415 Total bonds ​ $ 169,359 ​ $ 173,397 ​

We withdrew our Hart-Scott Rodino filings and were required to pay a termination fee of $23.0 million to the seller under the terms of the purchase agreement. In connection with the termination of the SPI acquisition, the Company terminated the commitments with respect to its undrawn Term Facility Two which was provided pursuant to Amendment No. 4. All other terms of the Company’s Credit Agreement, as amended, remain in full force and effect. ​ On May 3, 2024, our Board authorized the 2024 Repurchase Program, pursuant to which the Company may purchase up to $1.0 billion of our common stock.  Share repurchases may be executed through various means including open market purchases, privately negotiated transactions, accelerated share repurchase transactions, or other available means.  The 2024 Repurchase Program does not obligate the Company to purchase any shares and has no expiration date.  Authorization for the 2024 Repurchase Program may be terminated, increased, or decreased by the Board at its discretion at any time. ​ On May 3, 2024, we entered into an agreement to acquire the assets of the residential insulation business Insulation Works, Inc., which is expected to close in mid-May 2024. This installation acquisition will enhance our presence in the Arkansas market and extend our expertise to the agricultural market. The purchase price of approximately $25.2 million is expected to be funded by cash on hand. This acquisition will be accounted for as a business combination under ASC 805, “Business Combinations.” ​
