Note 2—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 8—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, end-user markets and methods of distribution) into three reportable segments: Americas, International, and Corporate.
The Americas segment is comprised of our operations in Northern North American and Latin American 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 of the end-customer.
Adjusted operating income (loss), adjusted operating margin, adjusted earnings before interest, taxes, depreciation and amortization (EBITDA) and adjusted EBITDA margin are the measures used by the chief operating decision maker to evaluate segment performance and allocate resources. Adjusted operating income (loss) is defined as operating income (loss) excluding restructuring charges, currency exchange (gains) losses, product liability expense, loss on divestiture of Mine Safety Appliances Company, LLC ("MSA LLC"), transaction costs and acquisition-related amortization. Adjusted operating margin is defined as adjusted operating income (loss) divided by segment net sales to external customers. Adjusted EBITDA is defined as adjusted operating income (loss) plus depreciation and amortization. Adjusted EBITDA margin is defined as adjusted EBITDA divided by segment net sales to external customers.

Table of Contents
The accounting principles applied at the operating segment level in determining operating income (loss) are generally 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 9—Earnings (Loss) per Share
Basic earnings (loss) 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 (loss) 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.

(a) During periods in which the Company incurs a net loss, stock-based compensation awards are excluded from the computation of diluted earnings per share because their effect would be anti-dilutive. As such, during periods in which the Company incurs a net loss, diluted weighted-average shares outstanding are equivalent to basic weighted-average shares outstanding.

Note 10—Income Taxes
The Company's effective tax rate for the three months ended September 30, 2023, was 25.6%, which differs from the United States of America ("U.S.") federal statutory rate of 21% primarily due to higher earnings in higher tax jurisdictions and nondeductible compensation. The Company's effective tax rate for the three months ended September 30, 2022, was 26.0%, which differs from the U.S. federal statutory rate of 21% primarily due to state income taxes and nondeductible foreign exchange on entity closures.
The Company's effective tax rate for the nine months ended September 30, 2023, was 116.6%, which differs from the "U.S." federal statutory rate of 21% primarily due to the divestiture of MSA LLC and the non-deductible loss recorded on the derecognition of the product liability reserves and related assets. Refer to Note 17—Contingencies to the unaudited condensed consolidated financial statements in Part I Item 1 of this Form 10-Q for further information on this transaction. The Company's effective tax rate for the nine months ended September 30, 2022, was 24.4%, which differs from the U.S. federal statutory rate of 21% primarily due to state income taxes and nondeductible foreign exchange on entity closures.
At September 30, 2023, the Company had a gross liability for unrecognized tax benefits of $3.4 million. The Company has recognized tax benefits associated with these liabilities of $1.7 million at September 30, 2023. The gross liability includes amounts associated with foreign tax exposure in prior periods.
The Company recognizes interest and penalties related to unrecognized tax benefits in interest expense and operating expenses, respectively. The Company's liability for accrued interest related to uncertain tax positions was $0.3 million at September 30, 2023.
We are subject to regular review and audit by both foreign and domestic tax authorities. While we believe our tax positions will be sustained, the final outcome of tax audits and related litigation may differ materially from the tax amounts recorded in our unaudited condensed consolidated financial statements.
Note 11—Stock Plans
The 2016 Management Equity Incentive Plan provides for various forms of stock-based compensation for eligible employees through May 2026 including stock options, restricted stock awards, restricted stock units and performance stock units. The 2017 Non-Employee Directors’ Equity Incentive Plan provides for grants of stock options, restricted stock awards and restricted stock units to non-employee directors through May 2027.
Stock compensation expense, included in Selling, general and administrative expense in the unaudited Condensed Consolidated Statements of Operations, is as follows:

Restricted stock awards and restricted stock units are valued at the market value of the stock on the grant date. A summary of restricted stock activity for the nine months ended September 30, 2023, is as follows:

| Shares |  | Weighted Average Grant Date Fair Value
Unvested at January 1, 2023 | 145,886 |  |  | $ | 137.36 |

Forfeited | (8,463) |  |  | 141.17 |
Unvested at September 30, 2023 | 171,532 |  |  | $ | 141.66 |

Performance stock units that have a market condition modifier are valued at an estimated fair value using a Monte Carlo model. The final number of shares to be issued for performance stock units granted in the first quarter of 2023 may range from 0% to 200% of the target award based on achieving the specified performance targets over the performance period plus an additional modifier based on total shareholder return ("TSR") over the performance period. The following weighted average assumptions were used in estimating the fair value of the performance stock units granted in the first quarter of 2023.

Fair value per unit | $131.46 |  |  |
Risk-free interest rate | 4.4% |  |  |
Expected dividend yield | 1.43% |  |  |
Expected volatility | 36.7% |  |  |
MSA stock beta | 0.739 |  |  |

The risk-free interest rate is based on the U.S. Treasury Constant Maturity rates as of the grant date converted into an implied spot rate yield curve. Expected dividend yield is based on the most recent annualized dividend divided by the one year average closing share price. Expected volatility is based on the three year historical volatility preceding the grant date using daily stock prices. Expected life is based on historical stock option exercise data.
A summary of performance stock unit activity for the nine months ended September 30, 2023, is as follows:

| Shares |  | Weighted Average Grant Date Fair Value
Unvested at January 1, 2023 | 178,760 |  |  | $ | 146.28 |
Granted | 77,654 |  |  | 132.39 |
Performance adjustments(a) | (3,009) |  |  | 127.40 |
Vested | (53,407) |  |  | 127.36 |
Forfeited | (10,146) |  |  | 147.83 |
Unvested at September 30, 2023 | 189,852 |  |  | $ | 146.14 |
(a)Performance adjustments relate primarily to the final number of shares issued for the 2020 performance unit awards which vested in the first quarter of 2023 at 94.9% of the target award based on both cumulative performance against EBITDA margin and revenue growth targets and MSA's TSR during the three-year performance period.

On May 24, 2021, the Company entered into a Fourth Amended and Restated Credit Agreement (the “Revolving Credit Facility" or "Facility”) that extended its term through May 24, 2026 and increased the capacity to $900.0 million. Under the amended agreement, the Company may elect either a Base rate of interest (“BASE”) or an interest rate based on the London Interbank Offered Rate (“LIBOR”). The BASE is a daily fluctuating per annum rate equal to the highest of (i) 0.00%, (ii) the Prime Rate, (iii) the Federal Funds Open Rate plus one half of one percent (0.5%), (iv) the Overnight Bank Funding Rate, plus one half of one percent (0.5%), or (v) the Daily LIBOR Rate plus one percent (1.00%). The Company pays a credit spread of 0 to 175 basis points based on the Company’s net EBITDA leverage ratio and elected rate (BASE or LIBOR). The Company has a weighted average revolver interest rate of 6.72% as of September 30, 2023. At September 30, 2023, $700.8 million of the existing $900.0 million 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 $400.0 million of capacity pending approval by MSA’s board of directors and from the bank group.
On July 1, 2021, the Company entered into a Third Amended and Restated Multi-Currency Note Purchase and Private Shelf Agreement (the “Prudential Note Agreement”) with PGIM, Inc. (“Prudential”). The Prudential Note Agreement provided for (i) the issuance of $100.0 million of 2.69% Series C Senior Notes due July 1, 2036 and (ii) the establishment of an uncommitted note issuance facility whereby the Company may request, subject to Prudential’s acceptance in its sole discretion, the issuance of up to $335.0 million aggregate principal amount of senior unsecured notes. As of September 30, 2023, the Company has outstanding £48.8 million (approximately $59.6 million at September 30, 2023) of 3.4% Series B Senior Notes due January 22, 2031. Remaining maturities of this note are £6.1 million (approximately $7.4 million at September 30, 2023) due January 22, 2024, with annual maturities of £6.1 million through January 2031.
On July 1, 2021, the Company entered into a Second Amended and Restated Master Note Facility (the “NYL Note Facility”) with NYL Investors. The NYL Note Facility provided for (i) the issuance of $100.0 million of 2.69% Series A Senior Notes due July 1, 2036, and (ii) the establishment of an uncommitted note issuance facility whereby the Company may request, subject to NYL Investors’ acceptance in its sole discretion, the issuance of up to $200.0 million aggregate principal amount of senior unsecured notes. On June 29, 2023, the Company issued $50 million of 5.25% Series B Senior Notes due July 1, 2028, pursuant to the NYL Note Facility (the "Notes"). The Notes bear interest at 5.25% per annum, payable semi-annually, and mature on July 1, 2028. The Notes provide for a principal payment of $25 million on July 1, 2027, with the remaining $25 million due on July 1, 2028. The Notes may be redeemed at the Company’s option prior to their maturity at a make-whole redemption price calculated as provided in the NYL Note Facility. 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, subject to certain exceptions and limitations, including carve-outs and baskets. All credit facilities exclude MSA LLC prior to the divestiture of this subsidiary on January 5, 2023, as discussed further in Note 17.

During August 2021 and June 2023, respectively, the Company amended its Revolving Credit Facility to transition from Sterling LIBOR reference rates to Sterling Overnight Interbank Average Rate ("SONIA") reference rates and from U.S. LIBOR reference rates to Secured Overnight Financing Rate ("SOFR") reference rates. The Company will apply the optional expedients in ASC 848, Reference Rate Reform, to these modifications driven by reference rate reform, accounting for the modifications as a continuation of the existing contracts. Therefore, these modifications will not require remeasurement at the modification date or a reassessment of previous accounting determinations. As such, the Company does not anticipate the change in reference rates will have an impact on the Company’s unaudited condensed consolidated financial statements.
On January 5, 2023, the Company entered into a new $250 million term loan facility to fund the divestiture of MSA LLC, a wholly owned subsidiary. Under the agreement, the Company may elect either BASE or an interest rate based on SOFR. The Company pays a credit spread of 0 to 200 basis points based on the Company's net EBITDA leverage ratio and elected rate. The Company had a Term Loan interest rate of 6.93% as of September 30, 2023.
As of September 30, 2023, 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 30, 2023, totaling $9.2 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. At September 30, 2023, the Company has $1.9 million of restricted cash in support of these arrangements.

We expect to make total contributions of $5.7 million to our pension plans in 2023, which are primarily associated with statutorily required plans in the International reporting segment.
Note 15—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 Operations. The notional amount of open forward contracts was $106.4 million and $103.0 million at September 30, 2023, and December 31, 2022, respectively.

Note 16—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 include the derivative financial instruments described in Note 15—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 investments in marketable securities and fixed rate long-term debt, we believe that the reported carrying amounts of our financial assets and liabilities approximate their fair values.
Our investments in available-for-sale marketable securities, primarily fixed income, were transferred to Sag Main Holdings, LLC, on January 5, 2023, as part of our MSA LLC divestiture as described in Note 17—Contingencies. Prior to the divestiture, these investments were valued at fair value using quoted market prices for similar securities or pricing models. Accordingly, the fair values of the investments were classified within Level 2 of the fair value hierarchy. The amortized cost basis of our investments was $9.9 million as of December 31, 2022. The fair value was $9.9 million as of December 31, 2022, which was reported in Investments, short-term in the accompanying unaudited Condensed Consolidated Balance Sheets. Prior to the divestiture, changes in fair value were recorded in Other comprehensive income (loss), net of tax. No impairment losses relating to these securities occurred during the three months ended March 31, 2023. All investments in marketable securities had maturities of one year or less and were in an unrealized loss position as of December 31, 2022.
The reported carrying amount of our fixed rate long-term debt was $309.6 million and $266.5 million at September 30, 2023, and December 31, 2022, respectively. The fair value of this debt was $255.1 million and $218.3 million at September 30, 2023, and December 31, 2022, 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 17—Contingencies
Product liability
The Company and its subsidiaries face an inherent business risk of exposure to legal 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. Product liability claims are categorized as either single incident or cumulative trauma.
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. The reserve for single incident product liability claims was $1.3 million at September 30, 2023 and $1.4 million at December 31, 2022. Single incident product liability benefit was $0.1 million for the nine months ended September 30, 2023, and expense was $0.1 million for the nine months ended September 30, 2022. Single incident product liability exposures are evaluated on an annual basis, or more frequently if changing circumstances warrant. Adjustments are made to the reserve as appropriate. The reserve has not been discounted to present value and does not include future amounts which will be spent to defend the claims.

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. Prior to the divestiture described below, one of the Company's former subsidiaries, MSA LLC, was 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.
Management previously established a reserve for MSA LLC's potential exposure to cumulative trauma product liability claims. Prior to its divestiture, MSA LLC's total cumulative trauma product liability reserve was $395.1 million, including $13.4 million for claims settled but not yet paid and related defense costs, as of December 31, 2022. The reserve included estimated amounts related to asserted and IBNR asbestos, silica, and coal dust claims expected to be resolved through the year 2075. The reserve was not discounted to present value and did not include future amounts which will be spent to defend the claims. Defense costs were recognized in the unaudited Condensed Consolidated Statements of Operations as incurred.
At December 31, 2022, $65.1 million of the total reserve for cumulative trauma product liability claims was recorded in the Insurance and product liability line within other current liabilities in the Consolidated Balance Sheets and the remainder, $330.0 million, is recorded in the Product liability and other noncurrent liabilities line.
Prior to the divestiture, MSA LLC's cumulative trauma product liability reserve was based upon an estimate of MSA LLC’s current and potential future liability for cumulative trauma product liability claims, in accordance with applicable accounting principles. See further discussion on the process and assumptions used to derive this estimate in Note 20—Contingencies of the consolidated financial statements in Part II Item 8 of MSA's Form 10-K for the year ended December 31, 2022.
On January 5, 2023, the Company entered into a membership interest purchase agreement (the “Purchase Agreement”) with Sag Main Holdings, LLC (the “Buyer”). The Buyer is a joint venture between R&Q Insurance Holdings Ltd. (“R&Q”) and Obra Capital, Inc. (“Obra”). Under the Purchase Agreement, on January 5, 2023, the Company transferred to the Buyer all of the issued and outstanding limited liability company interests of MSA LLC (the “Sale”). In connection with the closing, the Company contributed $341.2 million in cash and cash equivalents, while R&Q and Obra contributed an additional $35.0 million.
As MSA LLC was the obligor for the Company's legacy cumulative trauma product liability reserves and policyholder of the related insurance assets, the rights and obligations related to these items transferred upon the sale to the Buyer. In addition, pursuant to the Purchase Agreement, the Buyer 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.
Following the completion of the sale and transfer, the Company no longer has any obligation with respect to pending and future cumulative trauma product liability claims relating to these matters. As such, all legacy cumulative trauma product liability reserves, related insurance assets, and associated deferred tax assets of the divested subsidiary were derecognized from our balance sheet and the Company incurred a tax-effected loss on the divestiture of MSA LLC of $199.6 million, including transaction related costs of $5.6 million. R&Q and Obra's joint venture has assumed management of the divested subsidiary, including the management of its claims and associated assets.

Insurance Receivable and Notes Receivable, Insurance Companies
Many years ago, MSA LLC purchased insurance policies from various insurance carriers that, subject to common contract exclusions, provided coverage for cumulative trauma product liability losses (the "Occurrence-Based Policies").
Prior to the divestiture of MSA LLC, when adjustments were made to amounts recorded in the cumulative trauma product liability reserve, we calculated amounts due to be reimbursed pursuant to the terms of the negotiated Coverage-In-Place Agreements, including cumulative trauma product liability losses and related defense costs, and we recorded the amounts probable of reimbursement as insurance receivables.
Insurance receivables at December 31, 2022 totaled $127.6 million, of which $17.3 million was reported in Prepaid expenses and other current assets in the unaudited Condensed Consolidated Balance Sheets and $110.3 million was reported in Insurance receivables and other noncurrent assets.
A summary of insurance receivables balance and activity related to cumulative trauma product liability losses and divestiture of MSA LLC is as follows:

(In millions) |  | Nine Months Ended September 30, 2023 |  | Year Ended December 31, 2022

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 turnout gear from technical fabrics sourced from a small pool of specialty textile manufacturers. These protective fabrics have been tested and certified to meet industry standards, and some of them contain PFAS to achieve water, oil, or chemical resistance. At this time, no manufacturer of firefighter protective clothing is able to meet current National Fire Protection Association safety standards while offering coats or pants that are completely PFAS free.
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 Operations as incurred. Globe is also pursuing insurance coverage and indemnification related to the lawsuits. As of October 20, 2023, Globe was named as a defendant in 165 lawsuits comprised of approximately 8,432 claims, plus one action filed on behalf of a putative class of Florida firefighters and certain of their dependents.
MSA LLC is also a defendant in a number of PFAS lawsuits and the Buyer assumed responsibility for these and any similar future claims specific to MSA LLC in connection with the divestiture on January 5, 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.
The following table reconciles changes in the Company's accrued warranty reserve:

(In thousands) |  | Nine Months Ended September 30, 2023 |  | Year Ended December 31, 2022
Beginning warranty reserve |  | $ | 15,230 |  |  | $ | 12,423 |

Provision for product warranties and other adjustments |  | (91) |  |  | (1,106) |
Ending warranty reserve |  | $ | 14,607 |  |  | $ | 15,230 |

Warranty expense was $6.7 million and $9.0 million for the nine months ended September 30, 2023, and 2022, respectively, and is included in Costs of products sold on the unaudited Condensed Consolidated Statements of Operations.

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 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.”)
BUSINESS OVERVIEW
MSA is a global leader in the development, manufacture and supply of safety products and solutions that protect people and facility infrastructures. Recognized for their market leading innovation, many MSA products integrate a combination of electronics, mechanical systems and advanced materials to protect users against hazardous or life-threatening situations. The Company's comprehensive product line, which is governed by rigorous safety standards across highly regulated industries, is used by workers around the world in a broad range of markets, including fire service, oil, gas and petrochemical industry, construction, industrial manufacturing applications, utilities, mining and the military. MSA's core products include breathing apparatus, fixed gas and flame detection systems ("FGFD"), portable gas detection instruments, industrial head protection products, firefighter helmets and protective apparel, and fall protection devices. We are committed to providing our customers with service unmatched in the safety industry and, in the process, enhancing our ability to provide a growing line of safety solutions for customers in key global markets.
On January 5, 2023, the Company divested Mine Safety Appliances, LLC ("MSA LLC"), a wholly owned subsidiary that holds legacy product liability claims relating to coal dust, asbestos, silica, and other exposures, to Sag Main Holdings, LLC, a joint venture between R&Q Insurance Holdings Ltd. (“R&Q”) and Obra Capital, Inc. (“Obra”). In connection with the closing, MSA contributed $341.2 million in cash and cash equivalents, while R&Q and Obra contributed an additional $35.0 million. As a result of the transaction, MSA derecognized all legacy cumulative trauma product liability reserves, related insurance assets, and associated deferred tax assets of the divested subsidiary from its balance sheet in the first quarter of 2023. R&Q and Obra have assumed management of the divested subsidiary, including the management of its claims. Refer to Note 17—Contingencies to the unaudited condensed consolidated financial statements in Part I Item 1 of this Form 10-Q for further information.
We tailor our product 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 three reportable geographic segments: Americas, International and Corporate.
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 and China or are purchased from third-party vendors.
Corporate. The Corporate segment primarily consists 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 and administrative costs comprise the majority of the expense in the Corporate segment.

Table of Contents
PRINCIPAL PRODUCTS
The following is a brief description of each of our principal product categories:
MSA's corporate strategy includes a focus on driving sales of core products, where we have leading market positions and a distinct competitive advantage. Core products, as mentioned above, include breathing apparatus where self-contained breathing apparatus is the principal product, FGFD systems, portable gas detection instruments, industrial head protection products, firefighter helmets and protective apparel, and fall protection devices. Core products comprised approximately 92% and 89% of sales, respectively, for the three months ended September 30, 2023 and 2022. MSA also maintains a portfolio of non-core products. Non-core products reinforce and extend the core offerings, drawing upon our customer relationships, distribution channels, geographical presence and technical experience. These products are complementary to the core offerings and sometimes reflect more episodic or contract-driven growth patterns. Non-core products include air-purifying respirators, eye and face protection, ballistic helmets and gas masks.
MSA's diversified portfolio of safety products protects workers and facility infrastructure across a broad array of end markets including fire service, the oil, gas and petrochemical industry, construction, industrial manufacturing applications, heating, ventilation, air conditioning and refrigeration, utilities, mining and the military.
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, 2022.
RESULTS OF OPERATIONS
Three Months Ended September 30, 2023, Compared to Three Months Ended September 30, 2022
Net Sales. Net sales for the three months ended September 30, 2023, were $446.7 million, an increase of $65.0 million, or 17.0%, compared to $381.7 million in the same period last year, driven by volume growth and pricing actions. We saw healthy growth across product categories and both reporting segments. Please refer to the Net Sales table for a reconciliation of the quarter over quarter sales change.

Net Sales | Three Months Ended September 30, |  | Dollar Increase |  | Percent Increase
(In millions) | 2023 |  | 2022 |
Consolidated | $446.7 |  | $381.7 |  | $65.0 |  | 17.0%
Americas | 314.3 |  | 276.1 |  | 38.2 |  | 13.8%
International | 132.4 |  | 105.6 |  | 26.8 |  | 25.4%

Net Sales | Three Months Ended September 30, 2023 versus September 30, 2022
(Percent Change) | Americas | International | Consolidated
GAAP reported sales change | 13.8% | 25.4% | 17.0%
Currency translation effects | (1.5)% | (4.7)% | (2.3)%
Constant currency sales change | 12.3% | 20.7% | 14.7%

Note: Constant currency sales change is a non-GAAP financial measure provided by the Company to give a better understanding of the Company's underlying business performance. Constant currency sales change is calculated by deducting the percentage impact from currency translation effects from the overall percentage change in net sales.
Net sales for the Americas segment were $314.3 million in the third quarter of 2023, an increase of $38.2 million, or 13.8%, compared to $276.1 million in the third quarter of 2022. Constant currency sales in the Americas segment increased 12.3%. This growth was driven by increases in all products, particularly firefighter protective apparel, FGFD, fall protection, portable instruments and breathing apparatus associated with healthy demand and backlog conversion as a result of supply chain improvements.

Table of Contents
Net sales for the International segment were $132.4 million in the third quarter of 2023, an increase of $26.8 million, or 25.4%, compared to $105.6 million for the third quarter of 2022. Constant currency sales in the International segment increased 20.7% during the quarter. This growth was driven by increases in most products, particularly FGFD and breathing apparatus, associated with backlog conversion as a result of supply chain improvements.
Looking ahead, we continue to operate in a dynamic environment. There are a number of other evolving factors that will continue to influence our revenue and earnings outlook. These factors include, among other things, supply chain constraints, raw material availability, industrial employment rates, interest rate changes, military conflict, currency exchange volatility, the pace of economic recovery, and geopolitical risk. These or other conditions could impact our future results and growth expectations through the balance of 2023.
Refer to Note 8—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 quarter of 2023 was $218.8 million, an increase of $49.4 million or 29.1%, compared to $169.4 million for the third quarter of 2022. The ratio of gross profit to net sales was 49.0% in the third quarter of 2023 compared to 44.4% in the same quarter last year. Volume leverage, price/cost management, and productivity efforts contributed to the gross profit improvement.
Selling, general and administrative expenses. Selling, general and administrative ("SG&A") expenses were $102.2 million during the third quarter of 2023, an increase of $19.4 million or 23.5%, compared to $82.8 million for the same period a year ago. Overall, SG&A expenses were 22.9% of net sales during the third quarter of 2023, compared to 21.7% of net sales during the same period in 2022. Constant currency SG&A increased by approximately $17.7 million or 21.2%. The increase in SG&A was driven by the higher level of sales, increased variable compensation, targeted investments and inflation.
Please refer to the SG&A expenses table for a reconciliation of the quarter over quarter expense change.

Selling, general, and administrative expenses | Three Months Ended September 30, 2023 versus September 30, 2022
(Percent Change) | Consolidated
GAAP reported change | 23.5%
Currency translation effects | (2.3)%
Constant currency change | 21.2%

Research and development expense. Research and development expense was $17.7 million during the third quarter of 2023, an increase of $3.3 million, compared to $14.4 million during the third quarter of 2022. Research and development expense was 4.0% of net sales in the third quarter of 2023 compared to 3.8% in the same period of 2022.
During the third quarter of 2023 and 2022, we capitalized $3.3 million and $2.2 million of software development costs, respectively. Depreciation expense for capitalized software development cost of $2.7 million and $2.1 million during the third quarter of 2023 and 2022, respectively, was recorded in costs of products sold on the unaudited Condensed Consolidated Statements of Operations.
MSA remains committed to dedicating significant resources to research and development activities, including the development of technology-based safety solutions. 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 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 $21.0 million and $16.6 million during the third quarter of September 30, 2023, and 2022, respectively.
Restructuring charges. Restructuring charges of $3.3 million during the third quarter of 2023 were primarily related to manufacturing footprint optimization activities and ongoing initiatives to drive profitable growth. Restructuring charges of $0.9 million during the third quarter of 2022 were related to various optimization activities including the implementation of our European Shared Service Center in Warsaw, Poland and other optimization activities. We remain focused on executing programs to further optimize our cost structure.

Currency exchange. Currency exchange losses were $1.5 million in the third quarter of 2023 compared to $3.0 million in the third quarter of 2022. Currency exchange activity for both periods related primarily to foreign currency exposure on unsettled inter-company balances. Refer to Note 15—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.
Product liability expense. There was no product liability expense for the third quarter of 2023 due to our divestiture of MSA LLC, as discussed further in Note 17—Contingencies to the unaudited condensed consolidated financial statements in Part I Item 1 of this Form 10-Q. This compared to $4.0 million in the third quarter of 2022 which related primarily to defense costs incurred for cumulative trauma product liability claims.
GAAP operating income. Consolidated operating income for the third quarter of 2023 was $94.1 million compared to $64.3 million in the same period last year. The increase in operating income was primarily driven by higher sales and gross margin partially offset by increased SG&A.
Adjusted operating income. Americas adjusted operating income for the third quarter of 2023 was $93.9 million, an increase of $18.8 million or 25.1% compared to $75.1 million in the prior year third quarter. The increase in adjusted operating income is attributable to higher sales and gross margin.
International adjusted operating income for the third quarter of 2023 was $22.6 million, an increase of $14.1 million, or 167.2%, compared to $8.4 million in the prior year third quarter. The increase in adjusted operating income is primarily attributable to higher sales and gross margin.
Corporate segment adjusted operating loss for the third quarter of 2023 was $15.2 million, an increase of $6.8 million in comparison to an adjusted operating loss of $8.4 million in the third quarter of 2022, driven by higher performance based compensation expense related to sales growth and improved results from prior year.
The following tables represent a reconciliation from GAAP operating income to adjusted operating income (loss) and adjusted EBITDA. Adjusted operating margin % is calculated as adjusted operating income (loss) divided by net sales and adjusted EBITDA margin % is calculated as adjusted EBITDA divided by net sales.

Note: Adjusted operating income (loss) and adjusted EBITDA are non-GAAP financial measures. Adjusted operating income (loss) is reconciled above to the nearest GAAP financial measure, Operating income (loss), and excludes restructuring, currency exchange, product liability expense, loss on divestiture of MSA LLC, transaction costs and acquisition-related amortization. Adjusted EBITDA is reconciled above to the nearest GAAP financial measure, Operating income (loss) and excludes depreciation and amortization expense.

Total other expense (income), net. Total other expense, net, for the third quarter of 2023 was $6.5 million, compared to $3.6 million for the same period in 2022 driven primarily by higher interest expense related to higher interest rates, increased debt balances and decreased pension income driven by a lower expected rate of return.
Income taxes. The reported effective tax rate for the third quarter of 2023 was 25.6% compared to 26.0% for the third quarter of 2022. This decrease from the prior year is primarily due to a one time expense recorded in the third quarter of 2022 related to state income tax audits and an increase in the research and development credit, partially offset by higher profits in higher tax jurisdictions and an increase in nondeductible compensation.
We are subject to regular review and audit by both foreign and domestic tax authorities. While we believe our tax positions will be sustained, the final outcome of tax audits and related litigation may differ materially from the tax amounts recorded in our unaudited condensed consolidated financial statements.
Net income. Net income was $65.3 million for the third quarter of 2023, or $1.65 per diluted share compared to net income of $44.9 million, or $1.14 per diluted share, for the same period last year.

Note: Constant currency sales change is a non-GAAP financial measure provided by the Company to give a better understanding of the Company's underlying business performance. Constant currency sales change is calculated by deducting the percentage impact from currency translation effects from the overall percentage change in net sales.
Net sales for the Americas segment were $902.9 million in the nine months ended September 30, 2023, an increase of $148.8 million, or 19.7%, compared to $754.1 million in the same period last year. Constant currency sales in the Americas segment increased 18.8% compared to the prior year period. This growth was driven by increases in all products, particularly firefighter protective apparel, portable instruments and FGFD associated with healthy demand and improved output as well as backlog conversion as a result of continued progress with the supply chain.
Net sales for the International segment were $389.4 million in the nine months ended September 30, 2023, an increase of $58.8 million, or 17.8%, compared to $330.6 million in the same period last year. Constant currency sales in the International segment increased 18.3% during the period. This growth was driven by strength across most core products, partially offset by a decrease in firefighter helmets and protective apparel.

During the nine months ended September 30, 2023 and 2022, we capitalized $9.4 million and $6.5 million of software development costs, respectively. Depreciation expense for capitalized software development cost of $7.5 million and $5.7 million during the nine months ended September 30, 2023 and 2022, respectively, was recorded in costs of products sold on the unaudited Condensed Consolidated Statements of Operations.
MSA remains committed to dedicating significant resources to research and development activities, including the development of technology-based safety solutions. 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 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 $58.3 million and $49.5 million during the nine months ended September 30, 2023, and 2022, respectively.
Restructuring charges. Restructuring charges of $8.4 million during the nine months ended September 30, 2023 related to our ongoing initiatives to adjust our cost structure and improve productivity.

Product liability expense. Product liability expense for the nine months ended September 30, 2023 was minimal due to our divestiture of MSA LLC. This compared to $9.7 million in the same period of 2022 which related primarily to defense costs incurred for cumulative trauma product liability claims.
Loss on divestiture of MSA LLC. The $129.2 million pre-tax loss on divestiture of MSA LLC for the nine months ended September 30, 2023 relates to the derecognition of all legacy cumulative trauma product liability reserves and related insurance assets of the divested subsidiary during the first quarter of 2023. The loss also includes a $341.2 million contribution of cash and cash equivalents, as well as transaction related costs of $5.6 million. Refer to Note 17—Contingencies to the unaudited condensed consolidated financial statements in Part I Item 1 of this Form 10-Q for further information.
GAAP operating income. Consolidated operating income for the nine months ended September 30, 2023, was $129.1 million compared to $168.5 million in the same period last year. The decrease in operating results was primarily driven by the loss on divestiture of MSA LLC, partially offset by higher sales and gross margin.
Adjusted operating income. Americas adjusted operating income for the nine months ended September 30, 2023 was $260.4 million, an increase of $75.7 million, or 41.0%, compared to $184.7 million in the prior year.

Total other expense, net, for the nine months ended September 30, 2023 was $21.7 million, compared to total other income, net, of $1.0 million for the same period in 2022 driven primarily by higher interest expense related to higher interest rates, increased debt balances and decreased pension income driven by a lower expected rate of return.
Income taxes. The reported effective tax rate for the nine months ended September 30, 2023 was 116.6% compared to 24.4% for the same period in 2022. This significant variance from the prior year is primarily due to the divestiture of MSA LLC and the non-deductible loss recorded on the derecognition of the product liability reserves and related assets. Refer to Note 17—Contingencies to the unaudited condensed consolidated financial statements in Part I Item 1 of this Form 10-Q for further information on this transaction.

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, declared dividend payments and acquisitions. At September 30, 2023, approximately 42% 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 and a term loan, both due in 2026. At September 30, 2023, approximately 87% of our borrowings are denominated in U.S. dollars, which limits our exposure to currency exchange rate fluctuations.
At September 30, 2023, the Company had cash and cash equivalents totaling $164.5 million and access to sufficient capital, providing ample liquidity and flexibility to continue to maintain our balanced capital allocation strategy that prioritizes growth investments, funding our dividends and servicing debt obligations. Cash, cash equivalents and restricted cash increased $2.0 million during the nine months ended September 30, 2023. The cash flow activity reflects strong operating results and working capital performance being mostly offset by the MSA LLC divestiture as discussed below. This compared to cash increasing $19.8 million during the same period in 2022. We believe MSA's healthy balance sheet and access to significant capital at September 30, 2023, positions us well to navigate through challenging business conditions and supply chain constraints or other unexpected events.
Operating activities. Operating activities used cash of $66.1 million during the nine months ended September 30, 2023, compared to providing $103.9 million during the same period in 2022. The decreased operating cash flow as compared to the same period in 2022 was primarily related to the contribution of $341.2 million in the divestiture of MSA LLC. Refer to Note 17—Contingencies to the unaudited condensed consolidated financial statements in Part I Item 1 of this Form 10-Q for further information. This decrease was partially offset by working capital improvements, notably for inventories, and improved operating results.
Investing activities. Investing activities used cash of $28.3 million during the nine months ended September 30, 2023, compared to using $4.4 million during the same period in 2022. The increase in cash used in investing activities as compared to the same period in 2022 was primarily related to the absence of short-term investment activity. Our investments in available-for-sale marketable securities, primarily fixed income, were transferred to Sag Main Holdings, LLC, as part of our MSA LLC divestiture as described in Note 17—Contingencies to the unaudited condensed consolidated financial statements in Part I Item 1 of this Form 10-Q. We remain committed to evaluating additional acquisition opportunities that will allow us to continue to grow in key end markets and geographies.
Financing activities. Financing activities provided cash of $110.5 million during the nine months ended September 30, 2023, compared to using cash of $56.2 million during the same period in 2022. During the nine months ended September 30, 2023, we had net proceeds from long-term debt of $168.6 million to fund the MSA LLC divestiture as compared to net proceeds from long-term debt of $27.0 million during the same period in 2022. Since the MSA LLC divestiture in January 2023, we have paid down $146 million of our outstanding borrowings. We paid cash dividends of $55.0 million during the nine months ended September 30, 2023, compared to $53.4 million in the same period in 2022. We used cash of $3.9 million during the nine months ended September 30, 2023 to repurchase shares related to our employee stock compensation transactions. We used cash of $34.4 million during the nine months ended September 30, 2022, including $30.4 million related to our share repurchase program with the remainder related to employee stock compensation transactions.
CUMULATIVE TRANSLATION ADJUSTMENTS
The position of the U.S. dollar relative to international currencies, primarily the euro, British pound and Mexican peso, at September 30, 2023, resulted in a translation loss of $2.5 million being recorded to the cumulative translation adjustments shareholders' equity account during the nine months ended September 30, 2023, compared to a $58.1 million translation loss being recorded to the cumulative translation adjustments shareholders' equity account during the same period in 2022.
COMMITMENTS AND CONTINGENCIES
We made contributions of $4.3 million to our pension plans during the nine months ended September 30, 2023. We expect to make total contributions of approximately $5.7 million to our pension plans in 2023 primarily associated with statutorily required plans in the International segment.
The Company had outstanding bank guarantees and standby letters of credit with banks as of September 30, 2023, totaling $9.2 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 30, 2023, the Company has $1.9 million of restricted cash in support of these arrangements.

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 $17.3 million or 3.9% and $0.6 million or 0.9%, respectively, for the three months ended September 30, 2023.
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 30, 2023, we had open foreign currency forward contracts with a U.S. dollar notional value of $106.4 million. A hypothetical 10% strengthening or weakening of the U.S. dollar would result in a $10.6 million increase or decrease in the fair value of these contracts at September 30, 2023.
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 30, 2023, we had $309.6 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 $10.0 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 30, 2023, we had $435.2 million of variable rate borrowings. A 100 basis point increase or decrease in interest rates would have a $4.6 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.
