MSA SAFETY INCORPORATED

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Unaudited

Note 1—Basis of Presentation

The condensed consolidated financial statements of MSA Safety Incorporated and its subsidiaries ("“MSA"” or "“the Company"”) are unaudited. These unaudited condensed consolidated financial statements include all adjustments, consisting of normal recurring adjustments, considered necessary by management to fairly state the Company's results. Intercompany accounts and transactions have been eliminated. The results reported in these unaudited condensed consolidated financial statements are not necessarily indicative of the results that may be expected for the entire year. The December 31, ~~2024~~2025, Balance Sheet data was derived from the audited Consolidated Balance Sheets, but does not include all disclosures required by accounting principles generally accepted in the United States of America ("“U.S. GAAP"”). This Form 10-Q report should be read in conjunction with MSA's Form 10-K for the year ended December 31, ~~2024~~2025, which includes all disclosures required by U.S. GAAP.

In ~~December 2023,~~ the ~~Financial~~first ~~Accounting~~quarter ~~Standards~~2026, ~~Board (~~the ~~“FASB”)~~Company ~~issued~~early ~~ASU~~adopted ~~No.~~Accounting ~~2023-09~~Standards Update (“"ASU ~~2023-09”~~") 2025‑06, Targeted Improvements to ~~Income~~the ~~Tax~~Accounting ~~Disclosures~~for Internal-Use Software. The ASU ~~2023-09~~updates ~~requires~~guidance ~~disaggregated~~related ~~information~~to ~~about~~recognition aand ~~reporting~~capitalization ~~entity's~~costs ~~effective~~incurred ~~tax~~to ~~rate~~develop ~~reconciliation~~or asobtain ~~well~~internal-use assoftware, ~~information~~including oncertain ~~income~~cloud-based ~~taxes~~software ~~paid.~~arrangements, ~~This~~and ~~standard~~clarifies ~~also~~related ~~includes~~disclosure ~~certain~~requirements. ~~other~~The ~~amendments~~company toadopted ~~improve~~ the ~~effectiveness~~ASU prospectively as of ~~income~~January ~~tax~~1, ~~disclosures.~~2026, ~~ASU~~in ~~2023-09~~accordance iswith ~~effective~~the ~~for~~transition ~~public~~provisions ~~business~~of ~~entities~~the standard. Accordingly, ~~for~~amounts ~~annual~~capitalized ~~periods~~prior ~~beginning~~to ~~after~~the ~~December~~adoption ~~15,~~date ~~2024.~~were ~~With~~not adjusted, and the ~~exception~~new ofguidance ~~expanding~~applies ~~disclosures,~~only weto doqualifying ~~not~~costs ~~expect~~incurred after adoption. Therefore, the adoption of ~~ASU~~the ~~2023-09~~standard todid not have aan impact ~~material~~on ~~effect~~the onCompany’s ~~our~~condensed consolidated financial statements ~~taken~~for asthe aquarter ~~whole~~ended March 31, 2026.

In November 2024, the FASB issued ASU No. 2024-03 (“ASU 2024-03”), Disaggregation of Income Statement Expenses (“DISE”). ASU 2024-03 requires disaggregated disclosure of income statement expenses for public business entities. ASU 2024-03 does not change the expense captions an entity presents on the face of the income statement; rather, it requires disaggregation of certain expense captions into specified categories in disclosures within the footnotes to the financial statements. As revised by ASU No. 2025-01, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures, the provisions of ASU 2024-03 are effective for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027, with early adoption permitted. With the exception of expanding disclosures to include more granular income statement expense categories, we do not expect the adoption of ASU 2024-03 to have a material effect on our consolidated financial statements taken as a whole.

In September 2025, the FASB issued ASU No. 2025-06 (“ASU 2025-06”), Targeted Improvements to the Accounting for Internal-Use Software. ASU 2025-06 amends certain aspects of the accounting for a disclosure of software costs under ASC 350-40. ASU 2025-06 makes targeted improvements to ASC 350-40, but does not fully align the framework for accounting for internally developed software costs that are subject to ASC 350-40 with the framework applied to software to be sold or marketed externally that is subject to ASC 985-20. ASU 2025-06 also does not amend the guidance on costs of software licenses that are within the scope of ASC 985-20. ASU 2025-06’s amendments are effective for all entities for annual reporting periods beginning after December 15, 2027, and interim reporting periods within those annual reporting periods. The Company is still evaluating the impact that the adoption of ASU 2025-06 will have on the condensed consolidated financial statements.

Note 2—Revenue Recognition

We are the global leader in advanced industrial safety technology products and solutions and generate revenue primarily from manufacturing and selling a comprehensive line of safety products and solutions to protect the health and safety of workers and facility infrastructures around the world. Our customers generally fall into two categories: distributors orand end-users. All customer categories have similar nature, timing and uncertainty related to cash flows. As a result, the underlying principles of revenue recognition are identical for both categories of customers.

We account for revenue in accordance with ASC 606, Revenue from Contracts with Customers. Revenue from the sale of products and solutions is recognized when there is persuasive evidence of an arrangement and control passes to the customer, which generally occurs either when product is shipped to the customer or, in the case of certain customers, when product is delivered to the customer's site. We establish our shipping terms according to local practice and market characteristics. We do not ship product unless we have an order or other documentation authorizing shipment to our customers. Our payment terms vary by the type and location of our customer and the products and solutions offered; however, in most cases, the term between invoicing and when payment is due is not significant.

Revenue is measured as the amount of consideration we expect to receive in exchange for transferring goods or providing services. Amounts billed and due from our customers are classified as receivables on the unaudited Condensed Consolidated Balance Sheets. We make appropriate provisions for credit losses, which have historically been insignificant in relation to our net sales. Certain contracts with customers may have an element of variable consideration that is estimated when revenue is recognized under the contract. Variable consideration could include volume incentive rebates and performance guarantees. Rebates are based on achieving a certain level of purchases and other performance criteria that are documented in established distributor programs. These rebates are estimated based on projected sales to the customer and accrued as a reduction of net sales as they are earned by the customer. Sales, value added and other taxes collected with revenue-producing activities and remitted to governmental authorities are excluded from revenue.

Sales, value-added and other taxes collected with revenue-producing activities and remitted to governmental authorities are excluded from revenue.

Depending on the terms of the arrangement, we may defer revenue for which we have a future obligation, which may include leases where the Company is the lessor, training, extended warranty, software subscriptions, maintenance and technical services, until such time that the obligation has been satisfied. We use an observable price, or a cost plus margin approach when one is not available, to determine the stand-alone selling price for separate performance obligations. We have elected to recognize the cost for shipping and handling as an expense when control of the product has passed to the customer. These costs are included within the Cost of products sold line on the unaudited Condensed Consolidated Statements of Income. Amounts billed to customers for shipping and handling are included within the Net sales line on the unaudited Condensed Consolidated Statements of Income.

Performance Obligations

The Company recognizes revenue when performance obligations identified under the terms of the contract with its customers are satisfied, which generally occurs upon the transfer of control in accordance with the contractual terms and conditions of sale. For most contracts with customers, this results in point-in-time revenue recognition once contractual shipping terms are fulfilled.

Disaggregation of Revenue

Refer to Note 9—Segment Information for disaggregation of revenue by segment and product category, as we believe this best depicts how the nature, amount, timing and uncertainty of our revenue and cash flows are affected by economic factors.

Lessor Arrangements

The Company derives a portion of its revenue from various leasing contracts where the Company is the lessor, primarily managed fire service contracts. Such arrangements provide for recurring payments throughout the contract term. These payments cover equipment provided in addition to several services which include maintenance and interest.

Managed fire service contracts meet the criteria to be accounted for as sales-type leases. Under ASC 842, Leases, these contracts contain both lease and non-lease components. For a component to be separate, the customer would be able to benefit from the right of use of the component separately or with other resources readily available to the customer and the right of the use is not highly dependent or highly interrelated with the other rights to use the other underlying assets or components.

For managed fire service contracts, revenue from equipment provided is considered a lease component and recognized with point in time revenue recognition upon lease commencement. Upon the recognition of such revenue, an asset is established for the investment in sales-type leases. Maintenance revenue, which is considered a non-lease component, and interest are recognized monthly over the lease term. As of ~~September~~March 3031, ~~2025~~2026, remaining maintenance performance obligations for managed fire service contracts were $3027.90 million, which are expected to be recognized toas revenue over ~~approximately~~the ~~three~~remaining contract lives which are primarily two years.

Lease revenues and interest earned by the Company, which are included in the unaudited Condensed Consolidated Statements of Income, were not material tofor ~~either~~ the three month period ended ~~September~~March 3031, ~~2025~~2026, or ~~2024~~2025.

Practical Expedients and Exemptions

We do not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less and (ii) contracts for which we recognize revenue at the amount to which we have the right to invoice for services performed.

We do not assess whether a contract has a significant financing component if the expectation at contract inception is such that the period between payment by the customer and the transfer of the promised goods or services to the customer will be one year or less.

We generally expense sales commissions when incurred because the amortization period would have been one year or less. These costs are recorded within selling, general and administrative expenses in our unaudited Condensed Consolidated Statements of Income.

Note 3—Cash and Cash Equivalents

Several of the Company's subsidiaries participate in a notional cash pooling arrangement to manage global liquidity requirements. As part of a master netting arrangement, the participants combine their cash balances in pooling accounts at the same financial institution with the ability to offset bank overdrafts of one participant against positive cash account balances held by another participant. Under the terms of the master netting arrangement, the financial institution has the right, ability and intent to offset a positive balance in one account against an overdrawn amount in another account. Amounts in each of the accounts are unencumbered and unrestricted with respect to use. As such, the net cash balance related to this pooling arrangement is included in Cash and cash equivalents in the unaudited Condensed Consolidated Balance Sheets.

Note 9—Segment Information

The Company is organized into four geographical operating segments that are based on management responsibilities: Northern North America; Latin America; Europe, Middle East & Africa; and Asia Pacific. The operating segments have been aggregated (based on economic similarities, the nature of their products and solutions, end-user markets and methods of distribution) into ~~three~~two reportable segments: Americas, ~~International,~~ and ~~Corporate~~International.

The Americas segment is comprised of our operations in Northern North America and Latin America geographies. The International segment is comprised of our operations in all geographies outside of the Americas. Certain global expenses are allocated to each segment in a manner consistent with where the benefits from the expenses are derived.

The Company's sales are allocated to each segment based primarily on the ~~country~~ destination country of the end-customer.

~~The~~Adjusted ~~Company~~operating ~~adopted~~income ~~ASU~~is ~~No.~~the ~~2023-07~~measure ~~(“ASU~~used ~~2023-07”)~~by the chief operating decision maker, ~~Segment~~identified ~~Reporting~~as ~~(Topic~~our ~~280):~~President ~~Improvements~~and Chief Executive Officer, to ~~Reportable~~evaluate ~~Segment~~reportable ~~Disclosures~~segment ~~for~~performance ~~the~~and ~~year~~identify ~~ended~~opportunities ~~December~~when ~~31,~~allocating ~~2024,~~resources. ~~and~~Adjusted ~~applied~~operating itincome ~~retrospectively~~is ~~for~~defined ~~all~~as ~~prior~~operating ~~periods~~income ~~presented~~excluding restructuring charges, currency exchange, transaction costs and acquisition-related amortization.

Adjusted operating income (loss) is the measure used by the chief operating decision maker, identified as our President and Chief Executive Officer, to evaluate segment performance and identify opportunities when allocating resources. Adjusted operating income (loss) is defined as operating income excluding restructuring charges, currency exchange gains (losses), transaction costs and acquisition-~~related amortization.~~ 12-

Table of Contents

The accounting principles applied at the operating segment level in determining the segment measure of profit or loss are the same as those applied at the unaudited condensed consolidated financial statement level. Sales and transfers between operating segments are accounted for at market-based transaction prices and are eliminated in consolidation.

Reportable segment information is presented in the following table:

Note 10—Earnings per Share

Basic earnings per share is computed by dividing net income, after the deduction of preferred stock dividends and undistributed earnings allocated to participating securities, by the weighted average number of common shares outstanding during the period. Diluted earnings per share assumes the issuance of common stock for all potentially dilutive share equivalents outstanding not classified as participating securities. Participating securities are defined as unvested stock-based compensation awards that contain nonforfeitable rights to dividends.

The proceeds of the Notes were used on June 29, 2023, to pay down an equivalent amount of borrowings under the Company’s Revolving Credit Facility with PNC Bank, National Association, as Administrative Agent.

The Revolving Credit Facility, Prudential Note Agreement and NYL Note Facility require the Company to comply with specified financial covenants, including a requirement to maintain a minimum fixed charges coverage ratio of not less than 1.50 to 1.00, and a consolidated leverage ratio not to exceed 3.50 to 1.00; except during an acquisition period, defined as four consecutive fiscal quarters beginning with the quarter of acquisition, in which case the consolidated net leverage ratio shall not exceed 4.00 to 1.00; in each case calculated on the basis of the trailing four fiscal quarters. In addition, the agreements contain negative covenants limiting the ability of the Company and its subsidiaries to incur additional indebtedness or issue guarantees, create or incur liens, make loans and investments, make acquisitions, transfer or sell assets, enter into transactions with affiliated parties, make changes in its organizational documents that are materially adverse to lenders or modify the nature of the Company's or its subsidiaries' business.

As of ~~September~~March 3031, ~~2025~~2026, the Company was in full compliance with the restrictive covenants under its various credit agreements.

The Company had outstanding bank guarantees and standby letters of credit with banks as of ~~September~~March 3031, ~~2025~~2026, totaling $107.47 million, of which $1.5 million relate to the Revolving Credit Facility. The letters of credit serve to cover customer requirements in connection with certain sales orders and insurance companies. The Company is also required to provide cash collateral in connection with certain arrangements. As of ~~September~~March 3031, ~~2025~~2026, the Company has $01.92 million of restricted cash in support of these arrangements.

On May 6, 2025, the ~~company~~Company acquired M&C ~~TechGroup Germany GmbH and its affiliated companies ("M&C")~~ in a transaction valued at approximately $189 million, net of cash acquired. Refer to Note 15—Acquisitions for further information. The acquisition was financed by $137.3 million under the Revolving Credit Facility and cash on hand.

Note 15—Acquisitions

Acquisition of M&C

On May 6, 2025, the Company acquired 100% of the common stock of M&C in an all-cash transaction valued at approximately $189 million, net of cash acquired.

Headquartered in Ratingen, Germany, M&C provides a comprehensive range of gas analysis systems that detect, measure and monitor gases in critical environments. ~~The company~~M&C's product portfolio includes systems and solutions for gas sampling, gas conditioning, as well as advanced process control. M&C products and systems are used in a wide range of industries and applications, including energy, chemicals, utilities, manufacturing, food and beverage, and other industrial applications.

M&C’s operating results are included in our ~~unaudited condensed~~ consolidated financial statements from the acquisition date within the Americas and International reportable segments. The acquisition qualified as a business combination and was accounted for using the acquisition method of accounting.

The following table summarizes the preliminary fair values of M&C’s assets acquired and liabilities assumed at the acquisition date:

(In millions)	May 6, 2025
Current assets (including cash of $10.0)	$	3938.28
Property, plant and equipment and other noncurrent assets	4850.40
Customer relationships and other intangible assets	66.6
Goodwill	9291.6
Total assets acquired	$	~~246~~247.80
Deferred tax liability	$(24.9)	~~(24.7)~~
Other liabilities	(22.8)
Total liabilities assumed	$	(47.57)
Net assets acquired	$	199.3

AsThe ofamounts ~~September 30,~~in ~~2025,~~ the ~~purchase~~table ~~accounting~~above ~~for~~are ~~M&C~~substantially iscomplete, but subject to change ~~upon~~through ~~completion~~the second quarter of ~~the~~2026 ~~valuation~~based ofon ~~the~~management's ~~assets~~continued ~~acquired~~review of estimates and ~~liabilities~~assumptions ~~assumed,~~reflected ~~primarily~~in ~~for~~preliminary ~~review~~valuation data or receipt of additional information related to tax balances and liabilities assumed.

Assets acquired and liabilities assumed in connection with the acquisition were recorded at their preliminary fair values. Fair values were determined by management, based in part on an independent valuation performed by a third-21party valuation specialist. The valuation methods used to determine the fair value of intangible assets included the excess earnings approach for customer relationships using customer inputs and contributory charges; the relief from royalty method for trade name and developed technologies and the cost approach for assembled workforce, which is included in goodwill. Assumptions and estimates were involved in the application of these valuation methods, including forecasted sales volumes and prices, royalty rates, costs to produce, tax rates and amortization tax benefits, capital spending, discount rates, customer attrition rates, technology obsolescence assumptions and working capital changes. Cash flow forecasts were generally based on M&C pre-acquisition forecasts, coupled with estimated MSA financial synergies. Identifiable intangible assets with finite lives are subject to amortization over their estimated useful lives. The customer relationships, developed technology, and trade name acquired in the M&C transaction are being amortized over periods of 20 years, 8 years, and 20 years, respectively. Estimated future amortization expense related to the identifiable intangible assets is approximately $3 million for the remainder of 2026, approximately $4 million annually for 2027 through 2030, and $43.8 million thereafter.

Goodwill was calculated as the excess of the purchase price over the fair value of net assets acquired and represents the future economic benefits arising from other assets acquired that could not be individually identified and separately recognized. Among the factors that contributed to a purchase price in excess of the fair value of the net tangible and intangible assets acquired were the acquisition of an assembled workforce, the expected synergies and other benefits that we believe will result from combining the operations of M&C with our operations. Goodwill of $91.6 million related to the M&C acquisition was recorded, with $57.9 million and $33.7 million allocated to the International and Americas reportable segments, respectively. This Goodwill is nondeductible for tax purposes.

Note 17—Derivative Financial Instruments

As part of our currency exchange rate risk management strategy, we enter into certain derivative foreign currency forward contracts that do not meet the U.S. GAAP criteria for hedge accounting but have the impact of partially offsetting certain ~~of our~~ foreign currency exposures. We account for these forward contracts at fair value and report the related gains or losses in currency exchange losses, net, in the unaudited Condensed Consolidated Statements of Income. The notional amount of open forward contracts not designated as hedging instruments was $~~114~~109.82 million and $~~184~~113.04 million at ~~September~~March 3031, ~~2025~~2026, and December 31, ~~2024~~2025, respectively.

These instruments meet the ~~unaudited~~U.S. ~~Condensed~~GAAP ~~Consolidated~~criteria ~~Balance~~for ~~Sheets~~hedge ~~location~~accounting and ~~fair~~are ~~value~~accounted for under ASC 815, Derivatives and Hedging. For hedges of ~~assets~~forecasted transactions, significant characteristics and ~~liabilities~~expected ~~associated~~terms ~~with~~of ~~derivative~~a ~~financial~~forecasted ~~instruments:~~transaction are specifically identified, and it is probable that each forecasted transaction will occur. If it is deemed probable the forecasted transaction will not occur, then the gain or loss would be recognized immediately into net income. At March 31, 2026, and December 31, 2025, the notional amount of open foreign currency exchange forward contracts designated as cash flow hedges was $23.7 million and $31.6 million, respectively. See Note 7—Reclassifications Out of Accumulated Other Comprehensive Loss for information on unrealized loss deferred in Accumulated other comprehensive loss until the transactions related to these cash flow hedges affect earnings. Fair values of these contracts are derived using quoted forward foreign exchange prices to interpolate values of outstanding trades at the reporting date based on their maturities. All open foreign currency exchange forward contracts designated as cash flow hedges outstanding at March 31, 2026, will mature by December 2026.

Note 18—Fair Value Measurements

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value hierarchy consists of three broad levels, which gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The three levels of the fair value hierarchy are:

•Level 1—Observable inputs that reflect unadjusted quoted prices for identical assets or liabilities in active markets.

•Level 2—Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly.

•Level 3—Unobservable inputs for the asset or liability.

The valuation methodologies we used to measure financial assets and liabilities are also used to value the derivative financial instruments described in Note 17—Derivative Financial Instruments. We estimate the fair value of the derivative financial instruments, consisting of foreign currency forward contracts, based upon valuation models with inputs that generally can be verified by observable market conditions and do not involve significant management judgment. Accordingly, the fair values of the derivative financial instruments are classified within Level 2 of the fair value hierarchy. With the exception of our fixed rate long-term debt, we believe that the reported carrying amounts of our financial assets and liabilities approximate their fair values.

The reported carrying amount of our fixed rate long-term debt, including the current portion of long-term debt, was $~~299~~290.34 million and $~~303~~299.53 million at ~~September~~March 3031, ~~2025~~2026, and December 31, ~~2024~~2025, respectively. The fair value of this debt was $~~271~~260.50 million and $~~266~~272.45 million at ~~September~~March 3031, ~~2025~~2026, and December 31, ~~2024~~2025, respectively. The fair value of this debt was determined using Level 2 inputs by evaluating similarly rated companies with publicly traded bonds where available or current borrowing rates available for financings with similar terms and maturities.

Note 19—Commitments and Contingencies

Product liability

The Company and its subsidiaries face an inherent business risk of exposure to product liability claims arising from the alleged failure of our products to prevent the types of personal injury or death against which they are designed to protect.

Single incident product liability claims. Single incident product liability claims involve incidents of short duration that are typically known when they occur and involve observable injuries, which provide an objective basis for quantifying damages. Management has established reserves for the single incident product liability claims of the Company's various subsidiaries, including asserted single incident product liability claims and incurred but not reported ("IBNR") single incident claims. To determine the reserves, Management makes reasonable estimates of losses for single incident claims based on the number and characteristics of asserted claims, historical experience, sales volumes, expected settlement costs, and other relevant information. -21-

Cumulative trauma product liability claims. Cumulative trauma product liability claims involve alleged exposures to harmful substances (e.g., silica, asbestos and coal dust) that occurred years ago and may have developed over long periods of time into diseases such as silicosis, asbestosis, mesothelioma, or coal worker’s pneumoconiosis. A former subsidiary of the Company, MSA LLC, which was divested on January 5, 2023, under a membership interest purchase agreement (the "Purchase Agreement") with Sag Main Holdings LLC (the "Purchaser"), as further described in the Company’s Current Report on Form 8-K filed on January 6, 2023, has been named as a defendant in various lawsuits related to such claims. These lawsuits mainly involve respiratory protection products allegedly manufactured and sold by MSA LLC or its predecessors.

Cumulative trauma product liability claims. Cumulative trauma product liability claims involve alleged exposures to harmful substances (e.g., silica, asbestos and coal dust) that occurred years ago and may have developed over long periods of time into diseases such as silicosis, asbestosis, mesothelioma, or coal worker’s pneumoconiosis. A former subsidiary of the Company, Mine Safety Appliances Company, LLC (“MSA LLC”), which was divested on January 5, 2023, under a membership interest purchase agreement (the “Purchase Agreement”) with Sag Main Holdings LLC (the “Purchaser”), as further described in the Company’s Current Report on Form 8-K filed on January 6, 2023, has been named as a defendant in various lawsuits related to such claims. These lawsuits mainly involve respiratory protection products allegedly manufactured and sold by MSA LLC or its predecessors.

As MSA LLC was the obligor for the claims to which the Company's legacy cumulative trauma product liability reserves relate and the policyholder of the related insurance assets, the rights and obligations related to these items remained with MSA LLC when it transferred to the Purchaser's ownership pursuant to the Purchase Agreement. In addition, pursuant to the Purchase Agreement, the Purchaser and MSA LLC have agreed to indemnify the Company and its affiliates for legacy cumulative trauma product liabilities and other product liabilities, and a subsidiary of the Company has agreed to indemnify MSA LLC for all other historical liabilities of MSA LLC. This indemnification is not subject to any cap or time limitation. In connection with the sale, the Company and its Board of Directors received a solvency opinion from an independent advisory firm that MSA LLC was solvent and adequately capitalized after giving effect to the transaction.

Other Litigation

Globe, a subsidiary of the Company, is defending claims in which plaintiffs assert that certain products allegedly containing per- and polyfluoroalkyl substances (“PFAS”) have caused harm, including injury or health issues. PFAS are a large class of substances that are widely used in everyday products. Specifically, Globe builds firefighter turnout gear from technical fabrics sourced from a small pool of specialty textile manufacturers. These protective fabrics have been tested and certified to meet current National Fire Protection Association safety standards, and some of them as supplied to Globe contain or historically have contained PFAS to achieve performance characteristics such as water, oil, or chemical resistance.

Globe believes it has valid defenses to these claims. These matters are at a very early stage with numerous factual and legal issues to be resolved. Defense costs relating to these lawsuits are recognized in the unaudited Condensed Consolidated Statements of Income as incurred. Globe is also pursuing insurance coverage and indemnification related to the lawsuits. As of ~~October~~April 1530, ~~2025~~2026, Globe was named as a defendant in 1,~~085~~275 lawsuits comprised of 13about 21,~~140~~619 claims based on a largely common set of assertions, predominantly styled as individual personal injury claims and including several putative class actions. Certain of these lawsuits include MSA Safety ~~Incorporated~~Inc. or other Globe affiliates as defendants.

MSA LLC is also a defendant in a number of PFAS lawsuits predominantly relating to Aqueous Film-Forming Foam. The ~~purchaser~~Purchaser assumed responsibility for these and any similar future claims specific to MSA LLC, including such claims that have been or may be brought against MSA Safety ~~Incorporated~~Inc. or its subsidiaries, under the terms of the ~~purchase~~Purchase ~~agreement~~Agreement governing the Company's January 5, 2023, divestiture of MSA LLC. Further information about the transaction ~~and the purchase agreement~~ can be found in the Company’s Current Report on Form 8-K filed on January 6, 2023.

Product Warranty

The Company provides warranties on certain product sales. Product warranty reserves are established in the same period that revenue from the sale of the related products is recognized, or in the period that a specific issue arises as to the functionality of the Company's product. The determination of such reserves requires the Company to make estimates of product return rates and expected costs to repair or to replace the products under warranty.

The amounts of the reserves are based on established terms and the Company's best estimate of the amounts necessary to settle future and existing claims on products sold as of the balance sheet date. If actual return rates and/or repair and replacement costs differ significantly from estimates, adjustments to recognize additional cost of sales may be required in future periods.

Item 2.			Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis should be read in conjunction with the historical financial statements and other financial information included elsewhere in this quarterly report on Form 10-Q. This discussion may contain forward-looking statements that involve risks and uncertainties. The forward-looking statements are not historical facts, but rather are based on current expectations, estimates, assumptions and projections about our industry, business and future financial results. Our actual results could differ materially from the results contemplated by these forward-looking statements due to a number of factors, including but not limited to the effects of changes in U.S. trade policy and trade agreements, along with increased tariffs as well as those discussed in the sections of our annual report entitled “Forward-Looking Statements” and “Risk Factors,” and those discussed in our Form 10-Q quarterly reports filed after such annual report (such as in Part II, Item 1A, “Risk Factors.”)

A detailed listing of our significant product offerings in the aforementioned product groups above is included in MSA's Annual Report on Form 10-K for the year ended December 31, 2025.

We tailor our product and solution offerings and distribution strategy to satisfy distinct customer preferences that vary across geographic regions. To best serve these customer preferences, we have organized our business into four geographical operating segments that are aggregated into two reportable segments: Americas and International.

Americas. Our largest manufacturing and research and development facilities are located in the United States. We serve our markets across the Americas with manufacturing facilities in the U.S., Mexico and Brazil. Operations in the other countries within the Americas segment focus primarily on sales and distribution in their respective home country markets.

International. Our International segment includes companies in Europe, the Middle East and Africa ("“EMEA"”) and the Asia Pacific region. In our largest International subsidiaries (in Germany, France, U.K., Ireland and China), we develop, manufacture and sell a wide variety of products. In China, the products manufactured are sold primarily in China as well as in regional markets. Operations in other International segment countries focus primarily on sales and distribution in their respective home country markets. Although some of these companies may perform limited production, most of their sales are of products manufactured in our plants in Germany, France, the U.S., U.K., Ireland, Mexico, Morocco and China or are purchased from third-party vendors.

Corporate. ~~The~~ Corporate ~~segment~~expenses ~~primarily~~not ~~consists~~allocated to the reportable segments consist of general and administrative expenses incurred in our corporate headquarters, costs associated with corporate development initiatives, legal expense, interest expense, foreign exchange gains or losses and other centrally-managed costs. ~~Corporate~~General ~~general~~ and administrative costs and overhead comprise the majority of the ~~expense~~corporate inrelated ~~the Corporate segment~~expenses.

On May 6, 2025, we acquired M&C TechGroup and its affiliated companies ("M&C") in a transaction valued at approximately $189 million, net of cash acquired. Headquartered in Ratingen, Germany, M&C provides a comprehensive range of gas analysis systems that detect, measure and monitor gases in critical environments. M&C’s product portfolio includes systems and solutions for gas sampling, gas conditioning, as well as advanced process control.

The operating environment continues to be dynamic with continued macroeconomic, tariff and geopolitical uncertainty, particularly surrounding the conflict in the Middle East. We expect to generate full-year mid-single digit organic sales growth in 2026. We anticipate ongoing momentum in portable gas detection and fall protection as key growth drivers, as well as SCBA, which should benefit, in part, from the timing delays in 2025 that shifted some business to 2026. Furthermore, pricing actions in 2025 and 2026, along with moderate volume growth, should also support our outlook. Overall backlog remains healthy, and we have a solid commercial pipeline.

MSA has applied for International Emergency Economic Powers Act ("IEEPA") tariff refunds through US Customs and Border Protection’s (“CBP”) newly developed Consolidated Administration and Processing of Entries (“CAPE”) functionality within its Automated Commercial Environment (“ACE”) Portal. CBP has indicated refunds would be issued within 60-90 days of IEEPA tariff claim acceptance, but it is possible that our submission may not be accepted or that delays could occur for a variety of reasons. As of March 31, 2026, the Company has not recorded any amount related to potential tariff refunds in our unaudited condensed consolidated financial statements.

Refer to Note 9—Segment Information to the unaudited condensed consolidated financial statements in Part I Item 1 of this Form 10-Q, for information regarding sales by product group.

Gross profit. Gross profit for the ~~third~~three ~~quarter~~months ofended ~~2025~~March 31, 2026, was $~~217~~219.6 million, an increase of $1026.1 2 million or 413.95%, compared to $~~207~~193.54 million in the same period of ~~2024~~2025. The ratio of gross profit to net sales was 4647.54% induring the ~~third~~three ~~quarter~~months ofended ~~2025~~March 31, 2026, compared to 4745.9% in the same ~~quarter~~period ~~last~~of ~~year~~2025.

Selling, general and administrative expenses. Selling, general and administrative ("SG&A") expenses were $102.9 million during the third quarter of 2025, an increase of $7.8 million or 8.1%, compared to $95.1 million in the same period of 2024. SG&A expenses were 22.0% of net sales during both the third quarter of 2025 and 2024. SG&A includes $5.4 million of expenses associated with M&C operations and $1.9 million of strategic transaction costs. Organic SG&A decreased by approximately $0.9 million or 1.0% driven primarily by lower variable compensation and discretionary expense management partially offset by inflation and higher sales commission expense on detection growth. -25-

~~Please~~Selling, ~~refer~~general and administrative expenses. Selling, general and administrative (“SG&A”) expenses were $107.7 million during the three months ended March 31, 2026, an increase of $13.7 million or 14.6%, compared to $94.0 million in the same period of 2025.

Organic SG&A increased $4.3 million or 4.6%, driven primarily by higher variable compensation largely due to the cancellation of unvested equity awards in the prior period in accordance with plan terms, higher professional service costs and inflation.

Note: Organic SG&A change is a non-GAAP financial measure. See the "Non-GAAP Financial Measures" section below.

Research and development expense. Research and development expense was $16.5 million during the third quarter of 2025, a decrease of $0.2 million, compared to $16.7 million in the same period of 2024. Research and development expense was 3.5% of net sales in the third quarter of 2025 and 3.9% in the third quarter of 2024.

During the third quarter of 2025 and 2024, we capitalized $3.7 million and $3.2 million of software development costs, respectively. Depreciation expense for capitalized software development costs of $2.8 million and $2.7 million for the third quarter of 2025 and 2024, respectively, was recorded in Costs of products sold on the unaudited Condensed Consolidated Statements of Income.

MSA remains committed to dedicating significant resources to research and development activities, including the recently introduced ALTAIR io™ 6 portable gas detector and V-Gard H2® full brim safety helmet. As we continue to invest a significant portion of our new product development into technology-based safety solutions, we anticipate that the historical relationship of research and development expense and capitalized software development costs to net sales will continue to evolve; however, we do not anticipate reductions in the relative level of total spend on research and development activities on an annual basis. Total spend on both software development and research and development activities was $20.2 million and $19.9 million during the third quarter of September 30, 2025, and 2024, respectively.

Restructuring charges. Restructuring charges of $0.1 million during the third quarter of 2025 were primarily related to initiatives to right-size the organization in response to macroeconomic conditions. Restructuring charges of $1.2 million in the same period of 2024 were primarily related to initiatives to optimize our manufacturing footprint and improve productivity.

Currency exchange. Currency exchange losses were $3.9 million in the third quarter of 2025 compared to $3.0 million in the same period of 2024. The currency exchange activity for both periods related primarily to foreign currency exposure on unsettled inter-company balances. Refer to Note 17—Derivative Financial Instruments to the unaudited condensed consolidated financial statements in Part I Item 1 of this Form 10-Q, for information regarding our currency exchange rate risk management strategy.

GAAP operating income. Consolidated operating income for the third quarter of 2025 was $94.3 million compared to $91.5 million in same period of 2024. The increase in operating income was primarily related to the contribution from M&C.

Adjusted operating income. Americas adjusted operating income for the third quarter of 2025 was $88.7 million, a decrease of $3.1 million or 3.4% compared to $91.8 million in the same period of 2024. The decrease in adjusted operating income is primarily attributable to higher SG&A expense.

International adjusted operating income for the third quarter of 2025 was $24.8 million, an increase of $6.6 million, or 36.6%, compared to $18.2 million in the same period of 2024. The increase in adjusted operating income is attributable to higher sales volumes and the contribution from M&C.

Corporate segment adjusted operating loss for the third quarter of 2025 was $9.8 million, a decrease of $2.3 million, compared to an adjusted operating loss of $12.1 million in the same period of 2024, driven by decreased professional service fees and other discretionary expense management as well as decreased variable compensation partially offset by inflation.

Total other expense, net. Total other expense, net, for the third quarter of 2025 was $1.9 million, compared to $3.3 million for the same period of 2024, driven primarily by decreased interest expense related to lower interest rates as well as increased pension income driven by a higher expected rate of return.

Income taxes. The reported effective tax rate for the third quarter of 2025 was 24.7% compared to 24.4% in the same period of 2024. The increase from the prior year was primarily driven by discrete expense booked in the third quarter of 2025 related to the filing of prior period tax returns, partially offset by a discrete benefit booked in the third quarter of 2025 related to the statutory rate decrease in Germany.

On July 4, 2025, the United States enacted into law the One, Big, Beautiful Bill Act ("the Act"). The Act makes permanent key elements of the Tax Cuts and Jobs Act, including 100% bonus depreciation, domestic research cost expensing, and the business interest expense limitation. The Act has multiple effective dates, with certain provisions effective in 2025 and others implemented through 2027. The Company is currently assessing the impact of these provisions on our consolidated financial statements and currently do not expect a material impact.

Net income. Net income was $69.6 million for the third quarter of 2025, or $1.77 per diluted share, compared to $66.6 million, or $1.69 per diluted share, in the same period of 2024.

Note: Organic sales change is a non-GAAP financial measure. See the "Non-GAAP Financial Measures" section below.

Net sales for the Americas segment were $926.6 million in the nine months ended September 30, 2025, an increase of $16.9 million, or 1.9%, compared to $909.7 million in the same period of 2024. Organic sales in the Americas segment increased 1.7% during the period, driven by growth in detection and industrial PPE partially offset by a decrease in fire service. M&C added $8.9 million of sales to the Americas segment during the period.

Net sales for the International segment were $437.3 million in the nine months ended September 30, 2025, an increase of $38.6 million, or 9.7%, compared to $398.7 million in the same period of 2024. Organic sales in the International segment increased 3.3% during the period, driven by growth in detection and industrial PPE. M&C added $17.3 million of sales to the International segment during the period.

Refer to Note 9—Segment Information to the unaudited condensed consolidated financial statements in Part I Item 1 of this Form 10-Q, for information regarding sales by product group.

Gross profit. Gross profit for the nine months ended September 30, 2025, was $631.7 million, an increase of $5.7 million or 0.9%, compared to $626.0 million in the same period of 2024. The ratio of gross profit to net sales was 46.3% during the nine months ended September 30, 2025 compared to 47.8% in the same period of 2024. The decrease in gross profit margin is primarily related to inflation and transactional foreign currency challenges as well as to a lesser extent the impacts of tariffs and additional amortization related to the M&C acquisition partially offset by price realization and improved productivity.

Selling, general and administrative expenses. SG&A expenses were $308.9 million during the nine months ended September 30, 2025, an increase of $14.6 million or 4.9%, compared to $294.3 million in the same period of 2024. Overall, SG&A expenses were 22.6% of net sales during the nine months ended September 30, 2025, compared to 22.5% of net sales in the same period of 2024. SG&A includes $9.5 million of expenses associated with M&C operations and $10.0 million of strategic transaction costs. Organic SG&A decreased $5.6 million or 1.9%. driven primarily by the absence of the net cost for product related legal matter from the prior year, lower variable compensation, discretionary expense management and lower professional service costs mostly offset by inflation and higher sales commission expense on double-digit detection growth.

During the ~~nine~~three months ended ~~September~~March 3031, ~~2025~~2026, and ~~2024~~2025, we capitalized $~~10.~~4.2 million and $103.0 3 million of software development costs, respectively. ~~Depreciation~~Amortization expense for capitalized software development costs of $83.83 million and $8.2.9 million during the ~~nine~~three months ended ~~September~~March 3031, ~~2025~~2026, and ~~2024~~2025, respectively, was recorded in costs of products sold on the unaudited Condensed Consolidated Statements of Income.

As we continue to invest a significant portion of our new product development into technology-based safety solutions, we anticipate that the historical relationship of research and development expense ~~and capitalized software development costs~~ to net sales will continue to evolve; however, we do not anticipate reductions in the relative level of total spend on research and development activities on an annual basis. Total spend on both software development and research and development activities was $5920.6 million and $5919.70 million during the ~~nine~~three months ended ~~September~~March 3031, ~~2025~~2026, and ~~2024~~2025, respectively.

Restructuring charges. Restructuring charges of $2.53 million during the ~~nine~~three months ended ~~September~~March 3031, ~~2025~~2026, were primarily related to management restructuring, footprint optimization and other ongoing initiatives to right-size the organization in response to macroeconomic conditions ~~and ongoing initiatives to optimize our manufacturing footprint and improve productivity~~. Restructuring charges of $51.79 million in the same period of ~~2024~~2025 were primarily related to ~~our~~initiatives ~~ongoing~~to ~~initiatives~~right-size the organization in response to macroeconomic conditions, optimize our manufacturing footprint and improve productivity ~~as well as management restructuring~~.

Currency exchange losses, net. Currency exchange losses were $130.2 million during the ~~nine~~three months ended ~~September~~March 3031, ~~2025~~2026, compared to $4.71 million in the same period of ~~2024~~2025. The currency exchange activity for both periods related primarily to foreign currency exposure on unsettled inter-company balances. Refer to Note 17—Derivative Financial Instruments to the unaudited condensed consolidated financial statements in Part I Item 1 of this Form 10-Q, for information regarding our currency exchange rate risk management strategy.

GAAP operating income. Consolidated operating income for the ~~nine~~three months ended ~~September~~March 3031, ~~2025~~2026, was $~~257~~93.90 million compared to $~~271~~77.58 million in the same period of ~~2024~~2025. The ~~decrease~~increase in operating results was primarily driven by ~~increased~~higher ~~SG&A~~gross ~~expenses~~profit and lower currency exchange losses, partially offset by higher ~~sales~~SG&A and ~~lower~~ restructuring charges as discussed further above.

Adjusted operating income. Americas adjusted operating income for the ~~nine~~three months ended ~~September~~March 3031, ~~2025~~2026, was $~~260~~98.71 million, aan ~~decrease~~increase of $1519.84 million, or 524.7%, compared to $~~276~~78.57 million in the same period of ~~2024~~2025. The ~~decrease~~increase in adjusted operating income is attributable to ~~lower~~higher gross profit ~~and~~partially ~~slightly~~offset by higher SG&A expenses.

International adjusted operating income was $63.7 million, an increase of $7.8 million, or 13.9%, compared to $55.9 million in the same period of 2024. Higher sales volumes and the contribution from M&C were partially offset by higher SG&A expense.-26-

Corporate segment adjusted operating loss for the nine months ended September 30, 2025, was $31.7 million, a decrease of $6.7 million compared to an adjusted operating loss of $38.4 million in the same period of 2024 driven by decreased professional service fees and decreased variable compensation as well as other discretionary expense management partially offset by inflation.

Non-GAAP Financial Measures

This report includes certain non-GAAP financial measures and operating ratios derived from non-GAAP financial measures. These financial measures and ratios include organic (referred to in our historical filings as constant currency) sales change, organic SG&A change, adjusted operating income ~~(loss)~~, adjusted operating margin %, adjusted EBITDA and adjusted EBITDA margin %.

Organic sales and SG&A change are non-GAAP financial measures provided by the Company to give a better understanding of the Company's underlying business performance. Organic sales and SG&A change are calculated by deducting the percentage impact from currency translation effects as well as the impact from acquisitions and divestitures completed in the preceding 12 months from the overall percentage change in net sales and SG&A. The Company believes that organic sales and SG&A change are useful metrics for investors, as foreign currency translation can have a material impact on revenue and SG&A trends. Organic sales and SG&A change highlight ongoing business performance excluding the impact of fluctuating foreign currencies, acquisitions and divestitures.

Adjusted operating income ~~(loss)~~, adjusted operating margin %, adjusted EBITDA and adjusted EBITDA margin % are non-GAAP financial measures and operating ratios derived from non-GAAP measures. Total reportable segment adjusted operating income is reconciled above to the nearest GAAP financial measure, operating income, and excludes restructuring, currency exchange, ~~net cost for product related legal matter,~~ transaction costs and acquisition-related amortization. Total reportable segment adjusted EBITDA is reconciled above to the nearest GAAP financial measure, net income and, in addition to the items summarized above that are excluded from adjusted operating income (loss), excludes depreciation and amortization expense; interest expense; other income, net; and provision for income taxes. Adjusted operating margin % is defined as adjusted operating income (loss) divided by net sales to external customers and adjusted EBITDA margin % is defined as adjusted EBITDA divided by net sales to external customers. Management uses these measures internally to assess and better understand our underlying business performance and trends related to core business activities as well as to make strategic decisions about the business and allocate resources. Additionally, these non-GAAP financial measures provide information useful to investors in understanding our operating performance and trends, and to facilitate comparisons with the performance of our peers.

The non-GAAP financial measures and key performance indicators we use, and computational methods with respect thereto, may differ from the non-GAAP financial measures and key performance indicators, and computational methods, that our peers use to assess their performance and trends. The presentation of these non-GAAP financial measures does not comply with U.S. GAAP. These non-GAAP financial measures should be viewed as supplemental in nature, and not as a substitute for, or superior to, our reported results prepared in accordance with GAAP.

LIQUIDITY AND CAPITAL RESOURCES

Our main source of liquidity is operating cash flows, supplemented by borrowings. Our principal liquidity requirements are for working capital, capital expenditures, principal and interest payments on debt, dividend payments and share repurchases. At ~~September~~March 3031, ~~2025~~2026, approximately 47% of our long-term debt is at fixed interest rates with repayment schedules through 2036. The remainder of our long-term debt is at variable rates on an unsecured revolving credit facility due in 2030. At ~~September~~March 3031, ~~2025~~2026, approximately 8271% of our borrowings are denominated in U.S. dollars, which limits our exposure to currency exchange rate fluctuations.

We believe MSA's healthy balance sheet and access to significant capital at ~~September~~March 3031, ~~2025~~2026, positions us well to navigate through a dynamic operating environment and other unexpected events. We maintain a balanced capital deployment strategy that focuses on investing for organic growth and pursuing inorganic growth opportunities, ~~as well as~~ returning cash to shareholders in the form of dividends, and share buybacks.

At ~~September~~March 3031, ~~2025~~2026, the Company had cash and cash equivalents totaling $~~170~~180.02 million. Cash, ~~cash equivalents~~ and ~~restricted~~ cash equivalents increased $515.81 million during the ~~nine~~three months ended ~~September~~March 3031, ~~2025~~2026, compared to increasing $6.61 million during the same period in ~~2024~~2025. At ~~September~~March 3031, ~~2025~~2026, $~~965~~972.3 million of the existing $1.3 billion revolving credit facility was unused, including letters of credit issued under the facility. The facility also provides an accordion feature that allows the Company to access an additional $500.0 million of capacity pending approval by MSA’s board of directors and from the bank group. The Company also has access under the Prudential Note Agreement and NYL Note Facility, subject to the issuers' acceptance, to $195.0 million and $50.0 million aggregate principal amount, respectively, of senior unsecured notes.

Operating activities. Operating activities provided cash of $~~241~~75.57 million during the ~~nine~~three months ended ~~September~~March 3031, ~~2025~~2026, compared to $~~188~~61.58 million during the same period in ~~2024~~2025. The increased cash flow from operating activities was primarily related to higher operating results and lower cash used for variable compensation and other accruals as compared to the prior year ~~and lower cash usage for working capital needs. The working capital cash usage decrease related primarily to inventory~~, partially offset by higher cash ~~use~~usage for ~~accounts~~working ~~payable~~capital ~~and accounts receivable~~needs.

Investing activities. Investing activities used cash of $239.9 million during the nine months ended September 30, 2025, compared to using $39.7 million during the same period in 2024. The acquisition of M&C and capital expenditures, including a $19.6 million strategic footprint investment, drove the increase in cash outflows from investing activities during the nine months ended September 30, 2025. We remain committed to evaluating acquisition opportunities that will allow us to continue to grow in key end markets and geographies. -29-

Financing activities. Financing activities provided cash of $2.2 million during the nine months ended September 30, 2025, compared to using cash of $136.2 million during the same period in 2024. During the nine months ended September 30, 2025, we had net proceeds on long-term debt of $115.3 million, used primarily to fund the M&C acquisition, as compared to net payments of $51.0 million during the same period in 2024. We paid cash dividends of $61.6 million during the nine months ended September 30, 2025, compared to $58.7 million in the same period in 2024. We used cash of $50.0 million during the nine months ended September 30, 2025, to repurchase shares, including $40.0 million related to our share repurchase program, compared to $27.4 million in the same period in 2024, including $20.0 million related to our share repurchase program. The remainder in both periods related to our employee stock compensation programs.

The remainder in both periods related to our employee stock compensation programs.

CUMULATIVE TRANSLATION ADJUSTMENTS

The position of the U.S. dollar relative to international currencies, primarily the euro and British pound, at ~~September~~March 3031, ~~2025~~2026, resulted in a translation ~~gain~~loss of $656.01 million being recorded to the cumulative translation adjustments shareholders' equity account during the ~~nine~~three months ended ~~September~~March 3031, ~~2025~~2026, compared to a $122.85 million translation gain being recorded to the cumulative translation adjustments shareholders' equity account during the same period in ~~2024~~2025.

COMMITMENTS AND CONTINGENCIES

We made contributions of $52.72 million to our pension plans during the ~~nine~~three months ended ~~September~~March 3031, ~~2025~~2026. We expect to make net contributions between $78.0 million and $810.0 million to our pension plans in ~~2025~~2026, which are primarily associated with statutorily required plans in the International reporting segment.

The Company had outstanding bank guarantees and standby letters of credit with banks as of ~~September~~March 3031, ~~2025~~2026, totaling $107.47 million, of which $1.5 million relate to the senior revolving credit facility. These letters of credit serve to cover customer requirements in connection with certain sales orders and insurance companies. The Company is also required to provide cash collateral in connection with certain arrangements. At ~~September~~March 3031, ~~2025~~2026, the Company has $01.92 million of restricted cash in support of these arrangements.

We have purchase commitments for materials, supplies, services, and property, plant and equipment as part of our ordinary conduct of business.

Please refer to Note 19—Commitments and Contingencies to the unaudited condensed consolidated financial statements in Part I Item 1 of this Form 10-Q for further discussion on the Company's single incident and cumulative trauma product liabilities.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

We prepare our unaudited condensed consolidated financial statements in accordance with accounting principles generally accepted in the United States of America ("“U.S. GAAP"”). The preparation of these unaudited condensed consolidated financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and the related disclosures. We evaluate these estimates and judgments on an on-going basis based on historical experience and various assumptions that we believe to be reasonable under the circumstances. However, different amounts could be reported if we had used different assumptions and in light of different facts and circumstances. Actual amounts could differ from the estimates and judgments reflected in our unaudited condensed consolidated financial statements.

The more critical judgments and estimates used in the preparation of our unaudited condensed consolidated financial statements are discussed in Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations in our Annual Report on Form 10-K for the year ended December 31, ~~2024. During the nine months ended September 30,~~ 2025~~, we made an acquisition that raised business combinations to a critical accounting policy and estimate used in the preparation of our consolidated financial statements~~.

Business Combinations

In accordance with the accounting guidance for business combinations, the Company uses the acquisition method of accounting to allocate costs of acquired businesses to the assets acquired and liabilities assumed based on their estimated fair values at the dates of acquisition. The excess costs of acquired businesses over the fair values of the assets acquired and liabilities assumed will be recognized as goodwill. The valuations of the acquired assets and liabilities will impact the determination of future operating results. In addition to using management estimates and negotiated amounts, the Company uses a variety of information sources to determine the estimated fair values of acquired assets and liabilities including: third-party appraisals for the estimated value and lives of identifiable intangible assets and property, plant and equipment; third-party actuaries for the estimated obligations of defined benefit pension plans and similar benefit obligations; and legal counsel or other experts to assess the obligations associated with legal, environmental and other contingent liabilities.

The business and technical judgment of management was used in determining which intangible assets have indefinite lives and in determining the useful lives of finite-lived intangible assets in accordance with the accounting guidance for goodwill and other intangible assets.

Item 3.			Quantitative and Qualitative Disclosures About Market Risk

Market risk represents the risk of adverse changes in the value of a financial instrument caused by changes in currency exchange rates, interest rates and equity prices. We are exposed to market risks related to currency exchange rates and interest rates.

Currency exchange rate sensitivity. We are subject to the effects of fluctuations in currency exchange rates on various transactions and on the translation of the reported financial position and operating results of our non-U.S. companies from local currencies to U.S. dollars. A hypothetical 10% strengthening or weakening of the U.S. dollar would decrease or increase our reported sales and net income by approximately $2019.34 million, or 4.32%, and $12.60 million, or 2.37%, respectively, for the three months ended ~~September~~March 3031, ~~2025~~2026.

When appropriate, we may attempt to limit our transactional exposure to changes in currency exchange rates through forward contracts or other actions intended to reduce existing exposures by creating offsetting currency exposures. At ~~September~~March 3031, ~~2025~~2026, we had open foreign currency forward contracts with a U.S. dollar notional value of $~~114~~109.82 million. A hypothetical 10% strengthening or weakening of the U.S. dollar would result in a $1110.59 million increase or decrease in the fair value of these contracts at ~~September~~March 3031, ~~2025~~2026.

Interest rates. We are exposed to changes in interest rates primarily as a result of borrowing and investing activities used to maintain liquidity and fund business operations.

At ~~September~~March 3031, ~~2025~~2026, we had $~~299~~290.34 million of fixed rate debt which matures at various dates through 2036. The incremental increase in the fair value of fixed rate long-term debt resulting from a hypothetical 10% decrease in interest rates would be approximately $54.0 million. However, our sensitivity to interest rate declines and the corresponding increase in the fair value of our debt portfolio would unfavorably affect earnings and cash flows only to the extent that we elected to repurchase or retire all or a portion of our fixed rate debt portfolio at prices above carrying values.

At ~~September~~March 3031, ~~2025~~2026, we had $~~333~~326.23 million of variable rate borrowings. A 100 basis point increase or decrease in interest rates would have a $3.38 million impact on future annual earnings under our current capital structure.


Item 4.			Controls and Procedures

(a)Evaluation of disclosure controls and procedures. Based on their evaluation as of the end of the period covered by this Form 10-Q, the Company’s principal executive officer and principal financial officer have concluded that the Company’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934 (the “Exchange Act”)) are effective to ensure that information required to be disclosed by the Company in reports that it files or submits under the Exchange Act is (i) recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms and (ii) accumulated and communicated to our management, including the principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

(b)Changes in internal control. There were no changes in the Company’s internal control over financial reporting that occurred during the most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.
