Gross profit rose 23.5% to $408.0 million, driven by NDS, higher volumes and favorable price/cost and manufacturing, partly offset by higher transportation costs.

Filing Explained

NDS purchase accounting remains preliminary, while Teco’s July sale is complete and recorded a $4.0 million discontinued-operations loss.

Form 10-Q is the company’s unaudited quarterly report. This filing shows that the NDS acquisition was completed on February 2, 2026, but its purchase price allocation remains preliminary, so additional accounting adjustments may still be recorded.

The acquisition carried a preliminary fair value of $972.5 million and was primarily funded with cash on hand. At June 30, 2026, certain NDS international entities and one property remained classified as held for sale.

In July 2026, the company completed the sale of Teco S. and Teco Irrigation USA, which had been included in the held-for-sale group; the sale produced a $4.0 million loss recorded in discontinued operations for the quarter.

The remaining accounting uncertainty is the final valuation of assets acquired and liabilities assumed in the NDS transaction, which the filing says may be adjusted during the measurement period ending up to one year after closing.

Adjusted EBITDA financial
"Adjusted EBITDA, a non-GAAP measure, increased 28.8% to $358.3 million"
Adjusted EBITDA is a way companies measure how much money they make from their core operations, like running a business, by removing certain costs or income that aren’t part of regular business activities. It helps investors see how well a company is doing without distractions from unusual expenses or gains, making it easier to compare companies or track performance over time.
inventory step up financial
"Inventory step up related to NDS acquisition | 14,197 | —"
Term Loan Facility financial
"Payments on syndicated Term Loan Facility | — | ( 1,750 )"
A term loan facility is a type of loan provided by a lender that is repaid over a set period of time, usually with fixed payments. It functions like a large, upfront loan that a borrower agrees to pay back gradually, often used to fund major investments or projects. For investors, understanding a company's use of such loans helps assess its financial stability and risk level.
held for sale financial
"have been classified held for sale and are reported as assets held for sale"
An asset or a group of assets classified as 'held for sale' is one the company intends to sell rather than keep using, and management has committed to that plan with an active effort to find a buyer. Investors care because these items are removed from ongoing operating results and valued differently, offering a clearer view of the business’s continuing performance—think of it like marking a piece of furniture for the garage sale rather than counting it as part of your regular household setup.
performance-based Restricted Stock Units financial
"Performance-based restricted stock units | 6,787 | 2,424"
Performance-based restricted stock units are a type of employee equity award that converts into company shares only if predefined financial or operational targets are met over a set period. Think of it like a bonus check that becomes stock only when specific goals are hit; it ties pay to results, aligning managers’ incentives with shareholders. Investors care because these awards affect future share count, executive incentives, and signal how management’s success will be measured and rewarded.
free cash flow financial
"Free Cash Flow - Free cash flow is a non-GAAP financial measure"
Free cash flow is the amount of money a company has left over after paying all its expenses and investing in its business, like buying equipment or updating facilities. It shows how much cash is available to reward shareholders, pay down debt, or save for future growth. This helps investors understand if a company is financially healthy and able to grow.

Forward-Looking Statements
This Form 10-Q includes forward-looking statements. Some of the forward-looking statements can be identified by the use of terms such as “believes,” “expects,” “may,” “will,” “would,” “should,” “could,” “seeks,” “predict,” “potential,” “target,” “outlook,” “continue,” “intends,” “plans,” “projects,” “estimates,” “anticipates” or other comparable terms or the negative of those terms or similar expressions. These forward-looking statements include all matters that are not related to present facts or current conditions or that are not historical facts. They appear in a number of places throughout this Form 10-Q and include statements regarding our intentions, beliefs or current expectations concerning, among other things, our consolidated results of operations, financial condition, liquidity, prospects, growth strategies, and the industries in which we operate and include, without limitation, statements relating to our future performance.
Forward-looking statements are subject to known and unknown risks and uncertainties, many of which are beyond our control. We caution you that forward-looking statements are not guarantees of future performance and that our actual consolidated results of operations, financial condition, liquidity and industry development may differ materially from those made in or suggested by the forward-looking statements contained in this Form 10-Q. In addition, even if our actual consolidated results of operations, financial condition, liquidity and industry development are consistent with the forward-looking statements contained in this Form 10-Q, those results or developments may not be indicative of results or developments in subsequent periods. A number of important factors could cause actual results to differ materially from those contained in or implied by the forward-looking statements, including those reflected in forward-looking statements relating to our operations and business, the risks and uncertainties discussed in this Form 10-Q (including under the headings “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations”), and those described from time to time in our other filings with the SEC. Factors that could cause actual results to differ from those reflected in forward-looking statements relating to our operations and business include:
fluctuations in the price and availability of resins and other raw materials, new tariff and international trade policies and our ability to pass any increased costs of raw materials and tariffs on to our customers in a timely manner;
disruption or volatility in general business, political and economic conditions in the markets in which we operate;
cyclicality and seasonality of the non-residential and residential construction markets and infrastructure spending;
the risks of increasing competition in our existing and future markets;
uncertainties surrounding the integration and realization of anticipated benefits of acquisitions or doing so within the intended timeframe, including our ability to successfully integrate National Diversified Sales (“NDS”) into our business;
risks that the acquisition of NDS may involve unexpected costs, liabilities, risks that the cost savings and synergies from the acquisition of NDS may not be fully realized;
the effect of any claims, litigation, investigations or proceedings, including those described under “Part II - Item 1. Legal Proceedings” of this Form 10-Q;
the effect of weather or seasonality;
the loss of any of our significant customers;
the risks of doing business internationally;
the risks of conducting a portion of our operations through joint ventures;
our ability to expand into new geographic or product markets;

ADVANCED DRAINAGE SYSTEMS, INC. AND SUBSIDIARIES
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(UNAUDITED)
1.BACKGROUND AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Description of Business - Advanced Drainage Systems, Inc., incorporated in Delaware, and its subsidiaries (collectively referred to as “ADS” or the “Company”) designs, manufactures and markets innovative water management solutions in the stormwater and onsite septic wastewater industries, providing superior drainage solutions for use in the construction and agriculture marketplace. ADS’s products are used across a broad range of end markets and applications, including non-residential, residential, infrastructure and agriculture applications.
The Company is managed and reports results of operations in two reportable segments: Stormwater and Wastewater.
Historically, sales of the Company’s products have been higher in the first and second quarters of each fiscal year due to favorable weather and longer daylight conditions accelerating construction activity during these periods. Seasonal variations in operating results may also be impacted by inclement weather conditions, such as cold or wet weather, which can delay projects.
Basis of Presentation - The Company prepares its Condensed Consolidated Financial Statements in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The Condensed Consolidated Balance Sheet as of March 31, 2026 was derived from audited financial statements included in the Annual Report on Form 10-K for the year ended March 31, 2026 (“Fiscal 2026 Form 10-K”). The accompanying unaudited Condensed Consolidated Financial Statements contain all adjustments, of a normal recurring nature, necessary to present fairly its financial position as of June 30, 2026, the results of operations for the three months ended June 30, 2026 and cash flows for the three months ended June 30, 2026. The interim Condensed Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements, including the notes thereto, filed in the Company’s Fiscal 2026 Form 10-K.
Presentation - Prior period segment results and related disclosures have been recast to conform to the current period segment presentation. See “Note 14. Business Segment Information” for additional information.
Principles of Consolidation - The Condensed Consolidated Financial Statements include the Company, its wholly-owned subsidiaries, its majority-owned subsidiaries and variable interest entities of which the Company is the primary beneficiary. The Company uses the equity method of accounting for equity investments where it exercises significant influence but does not hold a controlling financial interest. Such investments are recorded in Other assets in the Condensed Consolidated Balance Sheets and the related equity earnings from these investments are included in Equity in net income of unconsolidated affiliates in the Condensed Consolidated Statements of Operations. All intercompany balances and transactions have been eliminated in consolidation.
Recent Accounting Guidance
Recently Adopted Accounting Pronouncement
Measurement of Credit Losses for Accounts Receivable and Contract Assets - In July 2025, the FASB issued an accounting standards update (“ASU”) which amends Accounting Standards Codification (“ASC”) 326-20 to provide a practical expedient and an accounting policy election related to the estimation of expected credit losses for current accounts receivable and current contract assets that arise from transactions accounted for under ASC 606. An entity is required to disclose whether it has elected to use the practical expedient and, if so, whether it has also applied the accounting policy election. The Company adopted this pronouncement effective April 1, 2026 and elected to use the practical expedient. The Company’s adoption did not have a material impact on the Company’s Condensed Consolidated Financial Statements.
Except for the pronouncements described above, there have been no new accounting pronouncements issued or adopted since the filing of the Fiscal 2026 Form 10-K that have significance, or potential significance, to the Consolidated Financial Statements.
2.REVENUE RECOGNITION
Revenue Disaggregation - The Company disaggregates Stormwater net sales by Domestic and International and further disaggregates Domestic by product type.

4.ACQUISITIONS
Acquisition of River Valley Pipe - On May 8, 2025, the Company completed its acquisition of the assets of River Valley Pipe LLC (“River Valley Pipe”), a privately-owned pipe manufacturing company located in the Midwest region of the United States. The preliminary fair value of consideration transferred was approximately $18.8 million. The acquisition was funded from cash on hand. River Valley Pipe is included in the Stormwater reportable segment. The purchase price allocation for assets acquired and liabilities assumed is complete and there were no changes to the valuations of assets acquired and liabilities assumed disclosed in the Fiscal 2026 Form 10-K.
Acquisition of NDS - On February 2, 2026, the Company completed the acquisition of the water management business of Norma Group SE, known as NDS. NDS expands the Company’s water management offering into complementary products through the addition of NDS’ residential water management, access box and irrigation solutions. The preliminary fair value of consideration transferred was approximately $972.5 million, which represented the purchase price of $984.9 million, net of cash acquired of $3.2 million and cash included in held for sale of $9.2 million. The preliminary purchase price excludes transaction costs. The acquisition was primarily funded from cash on hand. NDS is included in the Stormwater reportable segment.
Summary of Consideration Transferred - The Company has applied the acquisition method of accounting in accordance with ASC 805, Business Combinations (“ASC 805”) and recognized assets acquired and liabilities assumed at their fair value as of the date of acquisition, with the excess purchase consideration recorded to goodwill. As of June 30, 2026, there has been no change to the preliminary purchase price allocation of identified assets acquired and liabilities assumed as disclosed in the Fiscal 2026 Form 10-K. The purchase price allocation for assets acquired and liabilities assumed is preliminary and will be finalized when valuations are complete and final assessments of the fair value of acquired assets and assumed liabilities are completed. As the Company finalizes the estimation of the fair value of the assets acquired and liabilities assumed, additional adjustments may be recorded during the measurement period (up to one year from the closing date).
Pro Forma Financial Information - The unaudited pro forma information for the three months ended June 30, 2025 presented below includes the effects of the NDS acquisition as if it had been consummated as of April 1, 2024, with adjustments to give effect to pro forma events that are directly attributable to the acquisition of NDS. Adjustments include those related to the depreciation and amortization of acquired fixed and intangible assets, transaction costs, inventory step-up and the estimated tax impacts thereof. The unaudited pro forma information does not reflect any operating efficiency or potential cost savings that could result from the consolidation of NDS. Accordingly, the unaudited pro forma information is presented for informational purposes only and is not necessarily indicative of the actual results of the combined company if the acquisition had occurred at the beginning of the period presented, nor is it indicative of the future results of operations.

The Company determined Teco S.r.l., Kimplas Piping Systems Private Limited, Kimplas Limited, Teco Irrigation USA, Inc. and Fish Water Products Sdn. Bhd. (collectively, the “NDS International Entities”) met the held for sale criteria upon acquisition. As a result, the assets and liabilities of the NDS International Entities have been classified held for sale and are reported as assets held for sale and liabilities held for sale on the Consolidated Balance Sheet. The results of the NDS International Entities have been accounted for as discontinued operations and are reported as income or loss from discontinued operations, net of tax, on the Consolidated Statements of Operations. In addition to the NDS International Entities, one property is included as held for sale.
The Company measured the net assets of the disposal group at fair value less costs to sell. Costs to sell represent incremental direct costs expected to be incurred in connection with the disposal.

Other debt - Other debt includes equipment financing and the commercial loan related to the Company’s headquarters. The assets under the Equipment Financing acquired are titled to the Company and included in Property, plant and equipment, net on the Company's Condensed Consolidated Balance Sheet. The equipment financing has an initial term of between 12 and 84 months, based on the life of the equipment, and bears a weighted average interest rate of 1.8% as of June 30, 2026. The current portion of the equipment financing is $1.2 million, and the long-term portion is $1.6 million at June 30, 2026.
The Company entered into a commercial loan agreement of $27.2 million which matures on December 5, 2028. The agreement bears interest based on SOFR plus a margin of 285 basis points, requires interest only payments through December 5, 2026, and beginning January 5, 2027 through maturity, includes principal and interest payments.
Valuation of Debt - The carrying amounts of current financial assets and liabilities approximate fair value because of the immediate or short-term maturity of these items. The following table presents the carrying and fair value of the Company’s 2030 Notes, 2034 Notes and Equipment Financing for the periods presented:
June 30, 2026March 31, 2026

Total fair value$999,666 $1,002,752 $998,131 $1,003,056 
The fair values of the 2030 Notes and 2034 Notes were determined based on quoted market data for the Company’s 2030 Notes and 2034 Notes, respectively. The fair value of the Equipment Financing was determined based on a comparison of the interest rate and terms of such borrowings to the rates and terms of similar debt available for the period. The categorization of the framework used to evaluate the 2030 Notes, 2034 Notes and Equipment Financing are considered Level 2. The Company believes the carrying amount of the remaining long-term debt, including the Term Loan Facility, Revolving Credit Facility and Commercial loan agreement, is not materially different from its fair value as the interest rates and terms of the borrowings are similar to currently available borrowings.

14.BUSINESS SEGMENT INFORMATION
The Company operates its business in two distinct reportable segments: “Stormwater” and “Wastewater”, which are primarily organized based on products. The CODM for ADS is the Chief Executive Officer (“CEO”). The CEO reviews financial information and makes operational decisions based on Net sales and a measure of operating profit, Segment Adjusted EBITDA, a non-GAAP financial measure.
Certain selling and general and administrative expenses are not allocated to the segments, including non-operating functions such as legal, facilities management, and investor relations. A measure of assets is not applicable, as segment assets are not regularly reviewed by the CODM for evaluating performance or allocating resources. The Company does not aggregate operating segments to form reportable segments.

Item 2.         Management’s Discussion and Analysis of Financial Condition and Results of Operations
Unless the context otherwise indicates or requires, as used in this Quarterly Report on Form 10-Q (“Form 10-Q”), the terms “we,” “our,” “us,” “ADS” and the “Company” refer to Advanced Drainage Systems, Inc. and its directly- and indirectly-owned subsidiaries as a combined entity, except where it is clear that the terms mean only Advanced Drainage Systems, Inc. exclusive of its subsidiaries. We consolidate our joint ventures for purposes of GAAP, except for our South American Joint Venture.
Our fiscal year begins on April 1 and ends on March 31. Unless otherwise noted, references to “year” pertain to our fiscal year. For example, 2027 refers to fiscal 2027, which is the period from April 1, 2026 to March 31, 2027.
The following discussion and analysis of the financial condition and results of our operations should be read in conjunction with our Condensed Consolidated Financial Statements and related footnotes included elsewhere in this Form 10-Q and with the audited Consolidated Financial Statements included in our Fiscal 2026 Form 10-K, as filed with the Securities and Exchange Commission (the “SEC”) on May 21, 2026. In addition to historical condensed consolidated financial information, the following discussion contains forward-looking statements that reflect our plans, estimates and beliefs. Our actual results could differ materially from those discussed in the forward-looking statements. This discussion contains forward-looking statements that are based on the beliefs of our management, as well as assumptions made by, and information currently available to, our management. Our actual results could differ materially from those discussed in the forward-looking statements. For more information, see the section entitled “Forward-Looking Statements.”
Overview
ADS is the leading manufacturer of innovative water management solutions in the stormwater and onsite septic wastewater industries, providing superior drainage solutions for use in the construction and agriculture marketplaces. Our innovative products, for which we hold many patents, are used across a broad range of end markets and applications, including non-residential, residential, infrastructure and agriculture applications. We have established a leading position in many of these end markets by leveraging our national sales and distribution platform, industry-acclaimed engineering support, overall product breadth and scale plus manufacturing excellence.
Executive Summary
First Quarter Fiscal 2027 Results
Net sales increased 20.6% to $1,001.1 million
Net income from continuing operations increased 22.5% to $176.6 million
Adjusted EBITDA, a non-GAAP measure, increased 28.8% to $358.3 million
Net sales increased $171.2 million, or 20.6%, to $1,001.1 million, as compared to $829.9 million in the prior year quarter. Stormwater sales increased $157.8 million, or 24.2%, to $809.4 million. Stormwater sales include $94.7 million of revenue from the acquisition of NDS. Wastewater sales increased $13.4 million, or 7.5%, to $191.7 million.

Gross profit increased $77.6 million, or 23.5%, to $408.0 million as compared to $330.4 million in the prior year. The increase in gross profit is primarily driven by the acquisition of NDS, volume growth, and favorable price/cost and manufacturing costs, partially offset by higher transportation costs.
Adjusted EBITDA, a non-GAAP measure, increased $80.1 million, or 28.8%, to $358.3 million, as compared to $278.2 million in the prior year. As a percentage of Net sales, Adjusted EBITDA was 35.8% as compared to 33.5% in the prior year.

Our consolidated Cost of goods sold for the three months ended June 30, 2026 increased by $93.6 million, or 18.7%, and our consolidated Gross profit increased by $77.6 million, or 23.5%, compared to the same period in fiscal 2026. The increase in gross profit for Stormwater is primarily due to the acquisition of NDS, volume growth, and favorable price/cost and manufacturing costs, partially offset by higher transportation costs. The increase in gross profit for Wastewater was driven by volume.

Selling, general and administrative expenses for the three months ended June 30, 2026 increased $26.9 million from the same period in fiscal 2026 and as a percentage of Net sales, increased by 0.6%. The increase in Selling, general and administrative expenses was primarily due to the operating expenses of NDS, integration costs of $3.2 million and increased stock-based compensation due to performance.
Loss on disposal of assets and costs from exit and disposal activities - The loss on disposal in fiscal 2026 was due to exit and disposal activities. See “Note 3. Restructuring and Loss (Gain) on Disposal of Assets and Costs from Exit and Disposal Activities” for additional information.
Intangible amortization - Intangible amortization increased by $6.4 million primarily due to the increase in intangible assets due to the NDS acquisition.
Interest expense - Interest expense for the three months ended June 30, 2026 increased by $4.0 million from the same period in fiscal 2026. The increase was primarily due to increased debt levels.
Interest income and other, net - Interest income and other, net decreased by $5.3 million for the three months ended June 30, 2026 compared to the same period in fiscal 2026. The decrease was primarily due to decreased cash balances.
Income tax expense - The following table presents the effective tax rates for the periods presented:
Three Months Ended June 30,
20262025
Effective tax rate23.4 %24.6 %
The change in the effective tax rate for the three months ended June 30, 2026 was primarily related to a discrete income tax benefit for the change in valuation allowance on deferred tax assets for net losses on outside basis differences. See “Note 11. Income Taxes” for additional information.
Net loss from discontinued operations - The loss from discontinued operations was attributable to the NDS International entities classified as held for sale as of June 30, 2026.
Adjusted EBITDA and Adjusted EBITDA Margin - Adjusted EBITDA and Adjusted EBITDA Margin, which are non-GAAP financial measures, have been presented in this Form 10-Q as supplemental measures of financial performance that are not required by, or presented in accordance with GAAP and should not be considered as alternatives to net income as measures of financial performance or cash flows from operations or any other performance measure derived in accordance with GAAP. We calculate Adjusted EBITDA as net income from continuing operations before interest, income taxes, depreciation and amortization, stock-based compensation expense, non-cash charges and certain other expenses. We calculate Adjusted EBITDA Margin as Adjusted EBITDA divided by Net sales.
Adjusted EBITDA and Adjusted EBITDA Margin are included in this Form 10-Q because they are key metrics used by management and our board of directors to assess our consolidated financial performance. These non-GAAP financial measures are frequently used by analysts, investors and other interested parties to evaluate companies in our industry. In addition to covenant compliance and executive performance evaluations, we use these non-GAAP financial measures to supplement GAAP measures of performance to evaluate the effectiveness of our consolidated business strategies, to make budgeting decisions and to compare our performance against that of other peer companies using similar measures. We use Adjusted EBITDA Margin to evaluate our ability to generate profitable sales.
Adjusted EBITDA and Adjusted EBITDA Margin contain certain other limitations, including the failure to reflect our cash expenditures, cash requirements for working capital needs, cash expenditures to replace assets being depreciated and amortized and interest expense, or the cash requirements necessary to service interest on principal payments on our indebtedness. In evaluating Adjusted EBITDA and Adjusted EBITDA Margin, you should be aware that in the future we will incur expenses that are the same as or similar to some of the adjustments in this presentation, such as stock-based compensation expense, derivative fair value adjustments, and foreign currency transaction losses. Management compensates for these limitations by relying on our GAAP results and using non-GAAP measures on a supplemental basis.

Liquidity and Capital Resources
Historically, we have funded our operations through internally generated cash flow supplemented by debt financings, equity issuance and finance and operating leases. These sources have been sufficient historically to fund our primary liquidity requirements, including working capital, capital expenditures, debt service and dividend payments for our common stock. From time to time, we may explore additional financing methods and other means to raise capital. There can be no assurance that any additional financing will be available to us on acceptable terms or at all.
Free Cash Flow - Free cash flow is a non-GAAP financial measure that comprises cash flow from operations less capital expenditures and is used by management and our Board of Directors to assess our ability to generate cash. Accordingly, free cash flow has been presented as a supplemental measure of liquidity that is not required by, or presented in accordance with GAAP, because management believes that free cash flow provides useful information to investors and others in understanding and evaluating our ability to generate cash flow from operations after capital expenditures. Free cash flow is not a GAAP measure of our liquidity and should not be considered as an alternative to cash flow from operating activities as a measure of liquidity or any other liquidity measure derived in accordance with GAAP. Our measure of free cash flow is not necessarily comparable to other similarly titled captions of other companies due to different methods of calculation.
The following table presents a reconciliation of free cash flow to cash provided by operating activities, the most comparable GAAP measure, for each of the periods presented:

Revolver capacity$750,000 
Less: outstanding borrowings— 
Less: letters of credit(11,365)
Revolver available liquidity$738,635 
As of June 30, 2026, we had $24.8 million in cash that was held by our foreign subsidiaries, including $9.8 million held by our Canadian subsidiaries. We continue to evaluate our strategy regarding foreign cash, but our earnings in foreign subsidiaries still remain indefinitely reinvested, except for Canada. We plan to repatriate earnings from Canada and believe that there will be no additional tax costs associated with the repatriation of such earnings other than any potential non-U.S. withholding taxes.
Working Capital and Cash Flows
As of June 30, 2026, we had $900.9 million in liquidity, including $162.3 million of cash and $738.6 million in borrowings available under our Revolving Credit Agreement, net of outstanding letters of credit. We believe that our cash on hand, together with the availability of borrowings under our Credit Agreement and other financing arrangements and cash generated from operations, will be sufficient to meet our working capital requirements, anticipated capital expenditures, and scheduled principal and interest payments on our indebtedness for at least the next twelve months.
Working Capital - Working capital decreased to $655.3 million as of June 30, 2026, from $721.4 million as of March 31, 2026. The decrease in working capital is primarily due to decreased cash on hand and increased accounts payable offset by increased accounts receivable due to seasonality.

Net cash used in investing activities(55,006)(69,934)
Net cash used in financing activities(268,608)(31,132)
Operating Cash Flows - Cash flows from operating activities decreased $14.6 million during the three months ended June 30, 2026 primarily driven by changes in working capital.
Investing Cash Flows - Cash flows used in investing activities during the three months ended June 30, 2026 decreased by $14.9 million compared to the same period in fiscal 2026. The decrease in cash used in investing activities was due to the prior period acquisition of River Valley Pipe.
Capital expenditures totaled $57.2 million and $52.6 million for the three months ended June 30, 2026 and 2025, respectively. Our capital expenditures for the three months ended June 30, 2026 were used primarily to support facility expansions, equipment replacements and technology improvement initiatives. We also acquired $2.8 million of property, plant and equipment under finance leases, which includes material handling transportation equipment to update our fleet of forklifts, trucks and trailers.
We currently anticipate that we will make capital expenditures of approximately $200 million in fiscal year 2027, including approximately $110 million of open orders as of June 30, 2026. Such capital expenditures are expected to be financed using funds generated by operations.

Financing Cash Flows - During the three months ended June 30, 2026, cash used in financing activities included the repurchase of common stock of $233.2 million, $15.3 million of dividend payments, $10.7 million for shares withheld for tax purposes and $9.5 million of payments of finance lease obligations.
During the three months ended June 30, 2025, cash used in financing activities included $14.0 million of dividend payments, $8.3 million of payments of finance lease obligations and $6.7 million for shares withheld for tax purposes.
Financing Transactions - There have been no changes in our debt disclosures from those disclosed in “Liquidity and Capital Resources” in our Fiscal 2026 Form 10-K. We are in compliance with our debt covenants as of June 30, 2026.
Off-Balance Sheet Arrangements
Excluding the guarantees of 50% of certain debt of our unconsolidated South American Joint Venture as further discussed in “Note 8. Related Party Transactions” to the Condensed Consolidated Financial Statements, we do not have any other off-balance sheet arrangements. As of June 30, 2026, our South American Joint Venture had no outstanding debt subject to our guarantees. We do not believe that this guarantee will have a current or future effect on our financial condition, results of operations, liquidity or capital resources.
Critical Accounting Policies and Estimates
There have been no changes in critical accounting policies from those disclosed in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Fiscal 2026 Form 10-K, except as disclosed in “Note 1. Background and Summary of Significant Accounting Policies.”
Item 3.         Quantitative and Qualitative Disclosures about Market Risk
We are subject to various market risks, primarily related to changes in interest rates, credit, raw material supply prices and, to a lesser extent, foreign currency exchange rates. Our financial position, results of operations or cash flows may be negatively impacted in the event of adverse movements in the respective market rates or prices in each of these risk categories. Our exposure in each category is limited to those risks that arise in the normal course of business, as we do not engage in speculative, non-operating transactions. Our exposure to market risk has not materially changed from what we previously disclosed in Part II. Item 7A. “Quantitative and Qualitative Disclosures about Market Risk” of our Fiscal 2026 Form 10-K except as disclosed below.
Interest Rate Risk - We are subject to interest rate risk associated with our bank debt. A 1.0% increase in interest rates on our variable-rate debt would increase our annual forecasted interest expense by approximately $6.0 million based on our borrowings as of June 30, 2026. Assuming the Revolving Credit Facility is fully drawn, each 1.0% increase or decrease in the applicable interest rate would change our interest expense by approximately $11.4 million, for the twelve months ended June 30, 2026.
Item 4.         Controls and Procedures
Evaluation of Disclosure Controls and Procedures - The Company’s CEO and Chief Financial Officer (“CFO”) are responsible for evaluating the effectiveness of our disclosure controls and procedures as defined in the Securities Exchange Act of 1934, as amended (the “Exchange Act”), rules 13a-15(e) and 15d-15(e). The Company’s disclosure controls and procedures are designed to provide reasonable assurance that the information required to be disclosed in the Company’s reports under the Exchange Act, is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to management, including the Company’s CEO and CFO, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives, and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures.
Based on the evaluation of our disclosure controls and procedures, our CEO and CFO concluded that the Company’s disclosure controls and procedures were effective as of the end of the period covered by this report.
Changes in Internal Control over Financial Reporting - There were no change in the Company’s internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act that occurred during the three months ended June 30, 2026 that has materially affected, or is reasonably likely to materially affect, internal control over financial reporting.
