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;
•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;
•the risk associated with manufacturing processes;
•the effects of global climate change and any related regulatory responses;
•our ability to protect against cybersecurity incidents and disruptions or failures of our IT systems;
•our ability to assess and monitor the effects of artificial intelligence, machine learning, robotics and blockchain or other new approaches to data mining on our business and operations;
•our ability to manage our supply purchasing and customer credit policies;
•our ability to control labor costs and to attract, train and retain highly qualified employees and key personnel;
•our ability to protect our intellectual property rights;
•changes in laws and regulations, including environmental laws and regulations;
•our ability to appropriately address any environmental, social or governance concerns that may arise from our activities;
•the risks associated with our current levels of indebtedness, including borrowings under our existing credit agreement and outstanding indebtedness under our existing senior notes; and
•other risks and uncertainties, including those listed under “Part I - Item 1A. Risk Factors” in the Fiscal 2025 Form 10-K.
All forward-looking statements are made only as of the date of this report and we do not undertake any obligation, other than as may be required by law, to update or revise any forward-looking statements to reflect future events or developments. Comparisons of results for current and any prior periods are not intended to express any future trends, or indications of future performance, unless expressed as such, and should only be viewed as historical data.

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 three reportable segments: Pipe, Infiltrator Water Technologies, LLC (“Infiltrator”) and International. The Company also reports the results of its Allied Products and all other business segments as Allied Products & Other.
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, 2025 was derived from audited financial statements included in the Annual Report on Form 10-K for the year ended March 31, 2025 (“Fiscal 2025 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 December 31, 2025, the results of operations for the three and nine months ended December 31, 2025 and cash flows for the nine months ended December 31, 2025. 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 2025 Form 10-K.
Presentation - Prior period segment results and related disclosures have been recast to conform to the current period segment presentation. See “Note 13. 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
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 ASU is effective for fiscal years beginning after December 15, 2025, and interim reporting periods within those annual reporting periods, with early adoption permitted. The new guidance is to be applied prospectively. The Company is currently evaluating the impact this standard will have on the Condensed Consolidated Financial Statements.
Accounting for and Disclosure of Software Costs - In September 2025, the FASB issued an ASU which amends certain aspects of ASC 350-40. The amended guidance eliminates project stages and requires capitalizing software costs to begin when (1) management has authorized and committed to funding the software project and (2) it is probable that the project will be completed and the software will be used to perform the function intended. When evaluating if a project is probable to be completed, significant development uncertainty must be assessed. Additionally, disclosures for property, plant and equipment will be required for all capitalized software costs. The ASU is effective for fiscal years beginning after December 15, 2027, and interim reporting periods within those annual reporting periods, with early adoption permitted. The Company is currently evaluating the impact this standard will have on the Condensed Consolidated Financial Statements.
- 10 -
Except for the pronouncements described above, there have been no new accounting pronouncements issued or adopted since the filing of the Fiscal 2025 Form 10-K that have significance, or potential significance, to the Consolidated Financial Statements.
2.RESTRUCTURING AND LOSS (GAIN) ON DISPOSAL OF ASSETS AND COSTS FROM EXIT AND DISPOSAL ACTIVITIES
In fiscal 2026, the Company undertook certain restructuring and realignment activities (the “2026 Restructuring Plan”) to optimize the Company’s production, recycling and distribution network. Under the 2026 Restructuring Plan, during the three and nine months ended December 31, 2025, the Company recorded expense of $1.7 million and $17.7 million, respectively, related to the closure of one of the Company’s recycling facilities to optimize its recycling network, one offsite storage location and one distribution yard. The Company does not currently have an estimate of additional costs or an expected end date for the restructuring actions. The following table summarizes the activities included in Restructuring and realignment expense during the periods presented.

The restructuring liability is recorded in Other accrued liabilities in the Company’s Condensed Consolidated Balance Sheet.
Loss (Gain) on Disposal of Assets and Costs From Exit and Disposal Activities - The Company recorded a less than $0.1 million loss and a $16.4 million gain on disposal of assets in the three and nine months ended December 31, 2025, respectively. The sale of properties previously held-for-sale resulted in the gain of $18.1 million. The remaining balance is due to the sale or disposal of other property, plant and equipment.
3.ACQUISITIONS
Acquisition of Orenco - On October 1, 2024, the Company’s wholly-owned subsidiary, Infiltrator, completed the acquisition of Orenco Systems, Inc. (“Orenco”), a leading manufacturer of decentralized wastewater management products serving residential and non-residential end markets. The fair value of consideration transferred was approximately $236.3 million, which represented the purchase price of $255.0 million, net of cash acquired of $18.7 million. The purchase price excludes transactions costs. The acquisition was funded from cash on hand. Orenco will be included in the Infiltrator reportable segment.

The goodwill of $104.2 million represents the excess of consideration transferred over the fair value of assets acquired and liabilities assumed and is attributable to expected operating efficiencies. The goodwill is not deductible for income tax purposes and is assigned to Infiltrator.
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 Pipe reportable segment.
The following table summarizes the consideration transferred and the preliminary purchase price allocation of assets acquired and liabilities assumed. 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. Such finalization may result in material changes from the preliminary purchase price allocation. The Company's estimates and assumptions are subject to change during the measurement period (up to one year from the closing date), as the Company continues to finalize the valuations of assets acquired and liabilities assumed.

Senior Secured Credit Facility - In May 2022, the Company entered into a Second Amendment (the “Second Amendment”) to the Company's Base Credit Agreement with Barclays Bank PLC, as administrative agent under the Term Loan Facility and PNC Bank, National Association, as new administrative agent under the Revolving Credit Facility. Among other things, the Second Amendment (i) amended the Base Credit Agreement by increasing the Revolving Credit Facility (the “Amended Revolving Credit Facility”) from $350 million to $600 million (including an increase of the sub-limit for the swing-line sub-facility from $50 million to $60 million), (ii) extended the maturity date of the Revolving Credit Facility to May 26, 2027, (iii) revised the “applicable margin” to provide an additional step-down to 175 basis points (for Term Benchmark based loans) and 75 basis points (for base rate loans) in the event the consolidated senior secured net leverage ratio is less than 2.00 to 1.00, and (iv) reset the “incremental amount” and the investment basket in non-guarantors and joint ventures. The Second Amendment also revised the reference interest rate from LIBOR to SOFR for both the Amended Revolving Credit Facility and the Term Loan Facility. On November 26, 2025, the Company entered into a Third Amendment to the Company’s Base Credit Agreement modifying the termination date for the Amended Revolving Credit Facility. Letters of credit outstanding at December 31, 2025 and March 31, 2025 amounted to $10.1 million and $9.5 million, respectively, and reduced the availability of the Revolving Credit Facility.
The maturity date of the Term Loan Facility is September 24, 2026. As of December 31, 2025, the Company has continued to classify the Term Loan Facility as long-term debt as the Company has the intent and the ability to refinance these borrowings on a long-term basis as supported by the available capacity under the Revolving Credit Facility.
Senior Notes due 2027 - On September 23, 2019, the Company issued $350.0 million aggregate principal amount of 5.0% Senior Notes due 2027 (the “2027 Notes”) pursuant to an Indenture, dated September 23, 2019 (the “2027 Indenture”), among the Company, the guarantors party thereto (the “Guarantors”) and U.S. Bank National Association, as Trustee (the “Trustee”).

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 December 31, 2025. The current portion of the equipment financing is $1.2 million, and the long-term portion is $2.2 million at December 31, 2025.
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. As of December 31, 2025, the loan balance is classified as long-term debt in the Condensed Consolidated Balance Sheet.

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 2027 Notes, 2030 Notes and Equipment Financing for the periods presented:
 December 31, 2025 March 31, 2025
(In thousands)Fair ValueCarrying ValueFair Value Carrying Value
Senior Notes due 2027$350,119 $350,000 $344,036 $350,000

Total fair value$865,205 $853,374 $851,595 $855,988 
The fair values of the 2027 Notes and 2030 Notes were determined based on quoted market data for the Company’s 2027 Notes and 2030 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 2027 Notes, 2030 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.

13.BUSINESS SEGMENT INFORMATION
The Company operates its business in three distinct reportable segments: “Pipe”, “International” and “Infiltrator.” “Allied Products & Other” represents the Company’s Allied Products and all other business segments.

Our consolidated Net sales for the three months ended December 31, 2025 increased by $2.8 million, or 0.4%, compared to the same period in fiscal 2025. The overall decrease in Domestic Pipe Net sales was primarily driven by lower volume of sales in the residential and infrastructure end markets. Net sales of Infiltrator increased due to increased demand in the residential markets, primarily from growth in tanks and advanced treatment products. Allied Products & Other increased due to growth in the residential, non-residential and infrastructure end markets.

Our consolidated Net sales for the nine months ended December 31, 2025 increased by $85.1 million, or 3.7%, compared to the same period in fiscal 2025. The overall decrease in Domestic Pipe Net sales was primarily driven by lower demand in the residential and infrastructure end markets partially offset by improved demand in the non-residential construction market. Net sales for Infiltrator were driven by volume in the residential markets and the acquisition of Orenco. For the international segment, the decrease was driven by decreased volume. Allied Products & Other increased due to demand in the residential and non-residential construction markets.

The increase in Selling, general and administrative expenses was due to realignment expenses of $10.0 million, transaction costs of $17.3 million and operating expenses for Orenco.
Loss (gain) on disposal of assets and costs from exit and disposal activities - The gain on disposal in fiscal 2026 was due to the sale of properties held-for-sale partially offset by exit and disposal activities. See “Note 2. Restructuring and (Loss) Gain on Disposal of Assets and Costs from Exit and Disposal Activities” for additional information.

The change in the effective tax rate for the nine months ended December 31, 2025 was primarily driven by the decrease of the discrete income tax benefit related to the stock-based compensation windfall. See “Note 11. Income Taxes” for additional information.
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 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.

In addition to the available liquidity above, we have the ability to borrow up to $1.3 billion under our Senior Secured Credit Facility, subject to leverage ratio restrictions.
As of December 31, 2025, we had $41.1 million in cash that was held by our foreign subsidiaries, including $26.1 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 December 31, 2025, we had $1,598.1 million in liquidity, including $1,008.2 million of cash and $589.9 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.
As disclosed in “Note 15. Subsequent Events”, we primarily funded our acquisition of NDS in the fourth fiscal quarter of 2026 with cash on hand and the remainder with availability under our Revolving Credit Facility.
Working Capital - Working capital increased to $1,291.7 million as of December 31, 2025, from $926.4 million as of March 31, 2025. The increase in working capital is primarily due to increased cash on hand offset by changes in inventory and accounts receivable due to seasonality.

Operating Cash Flows - Cash flows from operating activities increased $238.9 million during the nine months ended December 31, 2025 primarily driven by changes in working capital.

Investing Cash Flows - Cash flows used in investing activities during the nine months ended December 31, 2025 decreased by $216.3 million compared to the same period in fiscal 2025. The decrease in cash used in investing activities was due to the proceeds from the sale of properties held-for-sale and the acquisition of Orenco in the prior year offset by the acquisition of River Valley Pipe.
Capital expenditures totaled $196.7 million and $166.4 million for the nine months ended December 31, 2025 and 2024, respectively. Our capital expenditures for the nine months ended December 31, 2025 were used primarily to support facility expansions, equipment replacements and technology improvement initiatives. We also acquired $36.6 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 $250 million in fiscal year 2026, including approximately $95 million of open orders as of December 31, 2025. Such capital expenditures are expected to be financed using funds generated by operations.
Financing Cash Flows - During the nine months ended December 31, 2025, cash used in financing activities included $42.1 million of dividend payments, $31.2 million of payments of finance lease obligations and $7.0 million for shares withheld for tax purposes. Cash provided by financing activities includes proceeds from the commercial loan agreement of $27.2 million.
During the nine months ended December 31, 2024, cash used in financing activities included the repurchase of common stock of $69.9 million, $37.3 million of dividend payments, $17.8 million of payments of finance lease obligations and $10.6 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 2025 Form 10-K. We are in compliance with our debt covenants as of December 31, 2025.
As of December 31, 2025, we have $408.0 million of debt under our Term Loan facility maturing within twelve months on its scheduled maturity. We have classified this debt as long-term debt as we have the intent and the ability to refinance these borrowings on a long-term basis as supported by the available capacity under the Revolving Credit Facility.
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 December 31, 2025, 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 2025 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 2025 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 $4.0 million based on our borrowings as of December 31, 2025. 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 $10.0 million, for the twelve months ended December 31, 2025.

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 changes 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 December 31, 2025 that has materially affected, or is reasonably likely to materially affect, internal control over financial reporting.

The Company is involved from time to time in various legal proceedings that arise in the ordinary course of business, including but not limited to commercial disputes, environmental matters, employee related claims, intellectual property disputes and litigation in connection with transactions including acquisitions and divestitures.

Please see “Note 10. Commitments and Contingencies,” of the Condensed Consolidated Financial Statements of this Form 10-Q for more information regarding legal proceedings.
Item 1A.     Risk Factors
The following risk factors are related to the acquisition of NDS. Additional important risk factors that could affect our operations and financial performance, or that could cause results or events to differ from current expectations, are described in “Part I, Item 1A — Risk Factors” of our Fiscal 2025 Form 10-K. These factors are further supplemented by those discussed in “Part II, Item 7A — Quantitative and Qualitative Disclosures about Market Risk” of our Fiscal 2025 Form 10-K and in “Part I, Item 3 — Quantitative and Qualitative Disclosures about Market Risk” and “Part II, Item 1 — Legal Proceedings” of this Quarterly Report on Form 10-Q.
Risks Relating to Our Acquisition of NDS
We may be unable to successfully integrate our and NDS’ businesses in order to realize the anticipated benefits of the acquisition or do so within the intended timeframe.
We will be required to devote significant management attention and resources to integrating the business practices and operations of NDS with our business. We may be unable to realize the planned synergies from the acquisition or other benefits in the timeframe that we expect or at all. We continue to assess synergies that we may realize as a combined company, the realization of which will depend on a number of factors.
The success of the acquisition, including anticipated synergies, benefits and cost savings, will depend, in part, on our ability to successfully combine and integrate our current operations with NDS’ business. If we experience difficulties with the integration process or other unforeseen costs, the anticipated benefits and cost savings of the acquisition may not be realized fully or at all, or may take longer to realize than expected. The integration planning and implementation process will result in significant costs and divert management attention and resources. These integration matters could have an adverse effect on our combined company for an undetermined period after completion of the acquisition. In addition, the actual cost savings of the acquisition could be less than anticipated, or otherwise offset by other factors.

Additional difficulties we may encounter as part of the integration process include the following:

•the costs of integration and compliance and the possibility that the full benefits anticipated to result from our acquisition of NDS will not be realized;
•any delay in the integration of management teams, strategies, operations, products and services;
•diversion of the attention of each company’s management as a result of our acquisition of NDS;
•differences in business backgrounds, corporate cultures and management philosophies that may delay successful integration;
•operating in foreign jurisdictions where we have no prior operating experience, including compliance, workforce and operational challenges;
•the ability to retain key employees;
•the ability to create and enforce uniform standards, controls, procedures, policies and information systems;
•the challenge of integrating complex systems, technology, networks and other assets of NDS into those of ours in a seamless manner that minimizes any adverse impact on customers, suppliers, employees and other constituencies;
•potential unknown liabilities and unforeseen increased expenses or delays associated with the acquisition, including costs to integrate NDS beyond current estimates and operating in; or
•the disruption of, or the loss of momentum in, each company’s ongoing businesses or inconsistencies in standards, controls, procedures and policies.
Any of these factors could adversely affect each company’s ability to maintain relationships with customers, suppliers, employees and other constituencies or our ability to achieve the anticipated benefits of the acquisition or could
- 30 -
reduce each company’s earnings or otherwise adversely affect our business and financial results after the acquisition. These risks are not limited to our acquisition of NDS and could also apply to our future acquisitions.
Uncertainties associated with our acquisition of NDS may cause a loss of management personnel and other key employees, which could adversely affect our future business, operations and financial results.
The acquisition of NDS could disrupt our and NDS’ businesses. We are dependent on the experience and industry knowledge of senior management and other key employees to execute our business plans, which could be disrupted by the unanticipated departure of any key member of our management team or employee base, as well as management or key employees of NDS. Our and NDS’ current and prospective employees may experience uncertainty about their roles within our company, which may have an adverse effect on the ability of each of us to attract or retain key management and other key personnel.
Accordingly, no assurance can be given that we will be able to attract or retain our and NDS’ key management personnel and other key employees to the same extent that our companies have previously been able to attract or retain such employees. In addition, because of the specialized and technical nature of our business, our future performance is dependent on the continued service of, and on our ability to attract and retain, qualified management, engineering, technical, marketing and support personnel. Competition for such personnel is intense, and we may be unable to continue to attract or retain such personnel.
Our results after our acquisition of NDS may suffer if we do not effectively manage our expanded operations following the acquisition or the business of NDS may underperform relative to our expectations.
Following our acquisition of NDS, the size and complexity of our business will increase significantly beyond the current size of either our or NDS’ existing business. Our future success depends, in part, upon our ability to manage this expanded business, which will pose substantial challenges for management, including challenges related to the management and monitoring of new operations and new types of manufacturing processes and products and associated increased costs and complexity. There can be no assurances that we will be successful after completion of the acquisition or that we will realize the expected benefits currently anticipated from our acquisition of NDS.
Additionally, we may not be able to maintain the levels of revenue, earnings or operating efficiency that we and NDS have achieved or might achieve separately. The business and financial performance of NDS is subject to certain risks and uncertainties, including the risk of the loss of, or changes to, its relationships with its customers. We may be unable to achieve the same growth, revenues and profitability that NDS has achieved in the past.
Item 2.        Unregistered Sales of Equity Securities and Use of Proceeds
In February 2022, our Board of Directors authorized a $1.0 billion common stock repurchase program and authorized an additional $1.0 billion in February 2026. Repurchases of common stock will be made in accordance with applicable securities laws. During the three months ended December 31, 2025, the Company did not repurchase any shares of common stock. As of December 31, 2025, approximately $147.7 million of common stock may be repurchased under the authorization. The stock repurchase program does not obligate us to acquire any particular amount of common stock and may be suspended or terminated at any time at our discretion.
Item 3.        Defaults Upon Senior Securities
None.
Item 4.        Mine Safety Disclosures
Not applicable.
