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"), net cost for product related legal matter, 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.

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.


	Three Months Ended June 30,				Six Months Ended June 30,
(In thousands, except per share values)	2024		2023		2024		2023

Diluted	$	1.83	$	1.70	$	3.30	$	(2.12)
(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 June 30, 2024, was 23.5%, which differs from the United States of America ("U.S.") federal statutory rate of 21% primarily due to state income taxes. The Company's effective tax rate for the three months ended June 30, 2023, was 23.3%, which differs from the U.S. federal statutory rate of 21% primarily due to state income taxes.

The Company's effective tax rate for the six months ended June 30, 2024, was 23.3%, which differs from the United States of America ("U.S.") federal statutory rate of 21% primarily due to state income taxes and nondeductible compensation. The Company's effective tax rate for the six months ended June 30, 2023, was 520.8%, 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—Commitments and Contingencies to the unaudited condensed consolidated financial statements in Part I Item 1 of this Form 10-Q for further information on this transaction.

At June 30, 2024, the Company had a gross liability for unrecognized tax benefits of $7.3 million. The Company has recognized tax benefits associated with these liabilities of $0.6 million at June 30, 2024. 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 $0.2 million at June 30, 2024.

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.

Forfeited	(21,904)	166.54
Unvested at June 30, 2024	189,659	$	150.08

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 2024 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 2024.


Fair value per unit			$181.31
Risk-free interest rate			4.34%
Expected dividend yield			1.19%
Expected volatility			25.9%
MSA stock beta			0.728

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.

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. The agreement was amended in August 2021 and June 2023 to transition from Sterling LIBOR reference rates and U.S. LIBOR reference rates. Under the amended agreement, the Company may elect either a Base rate of interest (“BASE”) or an interest rate based on Secured Overnight Financing Rate (“SOFR”). The BASE is a daily fluctuating per annum rate equal to the highest of (i) 0.00%, (ii) the Overnight Bank Funding Rate, plus 0.5%, (iii) the Prime Rate (iv) the Daily Simple SOFR rate, plus 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 SOFR). The Company has a weighted average revolver interest rate of 6.23% as of June 30, 2024. At June 30, 2024, $831.4 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, 2024, the Company entered into Amendment No. 3 to the 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 June 30, 2024, the Company has outstanding £42.7 million (approximately $54.1 million at June 30, 2024) of 3.4% Series B Senior Notes due January 22, 2031. Remaining maturities of this note are £6.1 million (approximately $7.7 million at June 30, 2024) due annually through January 2031.

On July 1, 2024, the Company entered into Amendment No. 3 to the Second Amended and Restated Master Note Facility (the “NYL Note Facility”) with NYL Investors.

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.

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 6.43% as of June 30, 2024.

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. All credit facilities exclude MSA LLC prior to the divestiture of this subsidiary on January 5, 2023, as discussed further in Note 17—Commitments and Contingencies to the unaudited condensed consolidated financial statements in Part I Item 1 of this Form 10-Q for further information on this transaction.

As of June 30, 2024, 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 June 30, 2024, totaling $10.2 million, of which $1.1 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 June 30, 2024, the Company has $2.0 million of restricted cash in support of these arrangements.

We expect to make net contributions of $5.3 million to our pension plans in 2024, 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 (gains) losses, net, in the unaudited Condensed Consolidated Statements of Operations. The notional amount of open forward contracts was $113.6 million and $110.9 million at June 30, 2024, and December 31, 2023, respectively.

The following table presents the unaudited Condensed Consolidated Balance Sheets location and fair value of assets and liabilities associated with derivative financial instruments:

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 are also used to value 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 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 was $304.1 million and $312.2 million at June 30, 2024, and December 31, 2023, respectively. The fair value of this debt was $263.9 million and $278.7 million at June 30, 2024, and December 31, 2023, 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—Commitments and 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 $1.4 million at June 30, 2024 and $1.3 million at December 31, 2023. Single incident product liability expense was $0.1 million for both the six months ended June 30, 2024, and 2023. 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.

During the second quarter of 2024, the Company recorded $5.0 million of net cost for product related legal matter. The expense is reflected within the selling, general and administration line of the unaudited Condensed Consolidated Statement of Operations.

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.

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 was 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.

MSA LLC was the obligor for the claims to which the Company's legacy cumulative trauma product liability reserves relate and policyholder of the related insurance assets. The rights and obligations related to these items remained with MSA LLC 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 transaction, 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. The Buyer has assumed management of the divested subsidiary, including the management of its claims and associated assets.

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 Operations as incurred. Globe is also pursuing insurance coverage and indemnification related to the lawsuits. As of July 17, 2024, Globe was named as a defendant in 659 lawsuits comprised of 12,137 claims, predominantly styled as individual personal injury claims and including two putative class actions. Certain of these lawsuits include MSA Safety 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 Buyer 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 Inc. or its subsidiaries, under the terms of the divestiture on January 5, 2023. Further information about the transaction 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.

The following table reconciles changes in the Company's accrued warranty reserve:


(In thousands)	Six Months Ended June 30, 2024		Year Ended December 31, 2023
Beginning warranty reserve	$	14,288	$	15,230
Warranty payments	(5,387)		(9,794)
Warranty claims	4,826		8,899
Provision for product warranties and other adjustments	208		(47)
Ending warranty reserve	$	13,935	$	14,288

Warranty expense was $5.0 million and $4.7 million for the six months ended June 30, 2024, and 2023, respectively, and is included in Costs of products sold on the unaudited Condensed Consolidated Statements of Operations.

Outstanding Performance Obligations

The Company derives a portion of its revenue from various leasing arrangements where the Company is the lessor, primarily fire service contracts entered into by Bristol. Such arrangements provide for monthly payments covering equipment provided, maintenance and interest. These arrangements meet the criteria to be accounted for as sales-type leases under Accounting Standards Codification ("ASC") 842 and contain both lease and non-lease components.

Revenue from equipment provided is considered a lease component and recognized with point in time revenue recognition upon lease commencement. Maintenance revenue, which is considered a non-lease component, and interest is recognized monthly over the lease term. As of June 30, 2024, the Company had remaining maintenance performance obligations of approximately $29.5 million which are expected to be recognized to revenue in approximately three years.

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 Safety Incorporated is the global leader in advanced safety products, technology and solutions. Driven by its singular mission of safety, the Company has been at the forefront of safety innovation since 1914, protecting workers and facility infrastructure around the world across a broad range of diverse end markets while creating sustainable value for shareholders. The Company's comprehensive product line, which is governed by rigorous safety standards across highly regulated industries, is used to protect workers and facility infrastructures around the world in a broad range of markets, including fire service, energy, utility, construction and industrial manufacturing applications as well as heating, ventilation, air conditioning and refrigeration ("HVAC-R"). The Company's product portfolio includes fire service where core products include self-contained breathing apparatus ("SCBA"), protective apparel and helmets; detection where core products include fixed gas and flame detection ("FGFD") systems and portable gas detection instruments; and industrial personal protective equipment ("PPE") where core products include industrial head protection and fall protection devices.

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, 2023.

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 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 (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, Morocco 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.

RESULTS OF OPERATIONS

Three Months Ended June 30, 2024, Compared to Three Months Ended June 30, 2023

Net Sales. Net sales for the three months ended June 30, 2024, were $462.5 million, an increase of $15.2 million, or 3.4%, compared to $447.3 million in the same period last year. Please refer to the Net Sales table for a reconciliation of the quarter over quarter sales change.


Net Sales	Three Months Ended June 30,		Dollar Increase	Percent Increase
(In millions, except percentage change)	2024	2023
Consolidated	$462.5	$447.3	$15.2	3.4%
Americas	314.7	308.4	6.3	2.0%
International	147.8	138.9	8.9	6.4%


Net Sales	Three Months Ended June 30, 2024 versus June 30, 2023
(Percent Change)	Americas	International	Consolidated
GAAP reported sales change	2.0%	6.4%	3.4%
Currency translation effects	0.4%	0.8%	0.5%
Organic constant currency sales change	2.4%	7.2%	3.9%


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

Net sales for the Americas segment were $314.7 million in the second quarter of 2024, an increase of $6.3 million, or 2.0%, compared to $308.4 million in the second quarter of 2023. Organic constant currency sales in the Americas segment increased 2.4%. This growth was driven by increases in detection and industrial PPE, partially offset by a decline in fire service.

Net sales for the International segment were $147.8 million in the second quarter of 2024, an increase of $8.9 million, or 6.4%, compared to $138.9 million for the second quarter of 2023. Organic constant currency sales in the International segment increased 7.2% during the quarter. Growth in fire service and detection was partially offset by a decline in industrial PPE.

The operating environment remains dynamic, and we continue to navigate these challenges to continue delivering solutions to our customers. Our end markets are generally healthy, demand trends lean positive, and we have executed initiatives to bring our backlog down to more normalized levels. Timing of orders can be a factor but we expect growth rates for the second half of 2024 to be similar to the first half. Looking forward, we continue to expect to generate mid-single digit sales growth in 2024.

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 second quarter of 2024 was $223.0 million, an increase of $9.2 million or 4.3%, compared to $213.8 million for the second quarter of 2023. The ratio of gross profit to net sales was 48.2% in the second quarter of 2024 compared to 47.8% in the same quarter last year. Improved productivity, price/cost management and favorable mix of higher margin products are the leading drivers of the increase year over year.

Selling, general and administrative expenses. Selling, general and administrative ("SG&A") expenses were $105.1 million during the second quarter of 2024, an increase of $8.8 million or 9.1%, compared to $96.3 million for the same period a year ago. Overall, SG&A expenses were 22.7% of net sales during the second quarter of 2024, compared to 21.5% of net sales during the same period in 2023. Organic constant currency SG&A increased by approximately $9.3 million or 9.7%. The increase in SG&A was driven by the higher level of sales, inflation, net cost for product related legal matter and higher professional service expense related to strategic initiatives partially offset by lower variable compensation.

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 June 30, 2024 versus June 30, 2023
(Percent Change)			Consolidated
GAAP reported change			9.1%
Currency translation effects			0.6%
Organic Constant currency change			9.7%

Note: Organic constant currency 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 $17.1 million during the second quarter of 2024, an increase of $1.1 million, compared to $16.0 million during the second quarter of 2023. Research and development expense was 3.7% of net sales in the second quarter of 2024 and 3.6% in the second quarter of 2023.

During the second quarter of 2024 and 2023, we capitalized $3.4 million and $3.1 million of software development costs, respectively. Depreciation expense for capitalized software development costs of $2.8 million and $2.5 million during the second quarter of 2024 and 2023, 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 $20.5 million and $19.1 million during the second quarter of June 30, 2024, and 2023, respectively.

Restructuring charges. Restructuring charges of $1.5 million during the second quarter of 2024 were primarily related to initiatives to optimize our manufacturing footprint and improve productivity. Restructuring charges of $3.4 million during the second quarter of 2023 were primarily related to our initiatives to adjust our cost structure and improve productivity.

Currency exchange. Currency exchange gains were $0.6 million in the second quarter of 2024 compared to losses of $3.1 million in the second quarter of 2023. During the second quarter of 2024, we recognized non-cash net cumulative translation gains of $1.2 million associated with certain foreign subsidiaries. The remaining currency exchange activity for both periods related primarily to foreign currency exposure on unsettled inter-company balances and recognized exchange loss for our Argentina affiliate operating in a hyper-inflationary environment. 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.

GAAP operating income. Consolidated operating income for the second quarter of 2024 was $99.9 million compared to $95.0 million in the same period last year. The increase in operating income was primarily driven by higher sales and gross profit partially offset by increased SG&A.

Adjusted operating income. Americas adjusted operating income for the second quarter of 2024 was $98.5 million, an increase of $3.7 million or 3.9% compared to $94.8 million in the prior year second quarter. The increase in adjusted operating income is attributable to higher sales and gross profit, partially offset by higher SG&A expenses to support business growth.

International adjusted operating income for the second quarter of 2024 was $24.3 million, an increase of $2.6 million, or 11.7%, compared to $21.7 million in the prior year second quarter. The increase in adjusted operating income is attributable to higher sales and gross profit, partially offset by higher SG&A expenses to support business growth.

Corporate segment adjusted operating loss for the second quarter of 2024 was $14.6 million, an increase of $1.8 million in comparison to an adjusted operating loss of $12.8 million in the second quarter of 2023, driven by inflation and increased professional service fees associated with various strategic initiatives partially offset by lower variable compensation.

Note: Adjusted operating income (loss), adjusted operating margin %, adjusted EBITDA and adjusted EBITDA margin % are non-GAAP financial measures. See the "Non-GAAP Financial Measures" section below.

Total other expense, net. Total other expense, net, for the second quarter of 2024 was $5.5 million, compared to $7.5 million for the same period in 2023, driven primarily by decreased interest expense related to reduced debt balances related to prior year borrowings associated with the MSA LLC divestiture as well as increased pension income driven by a higher expected rate of return partially offset by pension settlement expense recognized in the current year.

Income taxes. The reported effective tax rate for the second quarter of 2024 was 23.5% compared to 23.3% for the second quarter of 2023. This increase from the prior year is related to a one-time benefit recorded in the second quarter of 2023 related to prior year foreign tax returns, partially offset by a decrease in nondeductible compensation.

Net income. Net income was $72.2 million for the second quarter of 2024, or $1.83 per diluted share compared to $67.1 million, or $1.70 per diluted share, for the same period last year.

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

Net sales for the Americas segment were $610.2 million in the six months ended June 30, 2024, an increase of $21.6 million, or 3.7%, compared to $588.6 million in the same period last year. Organic constant currency sales in the Americas segment increased 3.6% compared to the prior year period. This growth was driven by increases in most products, particularly across fire service and FGFD partially offset by a decrease in portable instruments.

Net sales for the International segment were $265.5 million in the six months ended June 30, 2024, an increase of $8.6 million, or 3.3%, compared to $256.9 million in the same period last year. Organic constant currency sales in the International segment increased 3.3% during the period. This growth was driven by strength across fire service and FGFD, partially offset by decreases in portable instruments and industrial PPE.

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 six months ended June 30, 2024, was $418.6 million, an increase of $23.4 million or 5.9%, compared to $395.2 million during the same period last year. The ratio of gross profit to net sales was 47.8% during the six months ended June 30, 2024 compared to 46.7% during the same period last year. Volume leverage, price/cost management and productivity efforts contributed to the gross profit improvement.

Selling, general and administrative expenses. SG&A expenses were $199.2 million during the six months ended June 30, 2024, an increase of $11.8 million or 6.3%, compared to $187.4 million during the same period last year. Overall, SG&A expenses were 22.7% of net sales during the six months ended June 30, 2024, compared to 22.2% of net sales during the same period in 2023. Organic constant currency SG&A increased $12.0 million or 6.4%. The increase in SG&A was driven by the higher level of sales, inflation, net cost for product related legal matter and higher professional service expense partially offset by lower variable compensation.

Please refer to the selling, general, and administrative expenses table for a reconciliation of the period over period expense change.

Restructuring charges of $4.6 million during the six months ended June 30, 2024 were primarily related to ongoing initiatives to optimize our manufacturing footprint and improve productivity as well as management restructuring. Restructuring charges of $5.1 million during six months ended June 30, 2023 related to our ongoing initiatives to adjust our cost structure and improve productivity. We remain focused on executing programs to optimize our cost structure.

Currency exchange. Currency exchange losses were $1.7 million during the six months ended June 30, 2024, compared to $7.3 million in the same period of 2023. During 2024, we recognized non-cash net cumulative translation gains of $1.2 million associated with certain foreign subsidiaries. The remaining currency exchange activity for both periods related primarily due 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. Product liability expense for the six months ended June 30, 2024, and 2023, was minimal due to our divestiture of MSA LLC in January 2023, as discussed further in Note 17—Commitments and Contingencies to the unaudited condensed consolidated financial statements in Part I Item 1 of this Form 10-Q.

Loss on divestiture of MSA LLC. The $129.2 million pre-tax loss on divestiture of MSA LLC for the six months ended June 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—Commitments and 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 six months ended June 30, 2024, was $180.1 million compared to $34.9 million in the same period last year. The increase in operating results was driven by the higher sales and gross profit as well as the absence of loss on divestiture of MSA LLC that was recognized in 2023, partially offset by increased SG&A expense.

Adjusted operating income. Americas adjusted operating income for the six months ended June 30, 2024 was $184.7 million, an increase of $18.2 million, or 10.9%, compared to $166.5 million in the prior year. The increase in adjusted operating income is primarily attributable to higher sales and gross profit, partially offset by higher SG&A expense to support business growth.

International adjusted operating income for the six months ended June 30, 2024, was $37.8 million, an increase of $0.3 million, or 0.7%, compared to $37.5 million in the prior year. The increase in adjusted operating income is primarily attributable to higher sales.

Corporate segment adjusted operating loss for the six months ended June 30, 2024, was $26.3 million, an increase of $3.4 million compared to an adjusted operating loss of $22.9 million in the same period of 2023 driven by inflation and increased professional service fees associated with various strategic initiatives partially offset by lower variable compensation.

Total other expense, net. Total other expense, net, for the six months ended June 30, 2024 was $10.0 million, compared to total other income, net, of $15.2 million for the same period in 2023 due to decreased interest expense related to reduced debt balances related to prior year borrowings associated with the MSA LLC divestiture as well as increased pension income driven by a higher expected rate of return partially offset by pension settlement expense recognized in the current year.

Income taxes. The reported effective tax rate for the six months ended June 30, 2024 was 23.3% compared to 520.8% for the same period in 2023. This significant variance 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 in the prior year . Refer to Note 17—Commitments and Contingencies to the unaudited condensed consolidated financial statements in Part I Item 1 of this Form 10-Q for further information on this transaction.

Net income (loss) attributable to MSA Safety Incorporated. Net income was $130.4 million for the six months ended June 30, 2024, or $3.30 per diluted share compared to net loss of $83.1 million, or $(2.12) per diluted share, for the same period last year.

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 constant currency revenue growth, organic constant currency SG&A change, adjusted operating income (loss), adjusted operating margin %, adjusted EBITDA and adjusted EBITDA margin %.

Organic constant currency 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 constant currency sales and SG&A change are calculated by deducting the percentage impact from currency translation effects from the overall percentage change in net sales and SG&A. The Company believes that organic constant currency revenue growth 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 constant currency revenue growth and SG&A change highlight ongoing business performance excluding the impact of fluctuating foreign currencies, which is outside of the Company's control.

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. 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, net cost for product related legal matter, 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. Adjusted operating margin % is defined as adjusted operating income (loss) divided by segment net sales to external customers and adjusted EBITDA margin % is defined as adjusted EBITDA divided by segment net sales to external customers. These metrics are consistent with how the Company's chief operating decision maker ("CODM") evaluates segment results and makes strategic decisions about the business. 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.

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 allocate resources. 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, declared dividend payments and acquisitions. At June 30, 2024, approximately 52% 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 June 30, 2024, approximately 84% of our borrowings are denominated in U.S. dollars, which limits our exposure to currency exchange rate fluctuations.

At June 30, 2024, the Company had cash and cash equivalents totaling $146.8 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 $0.4 million during the six months ended June 30, 2024 compared to cash decreasing $15.6 million during the same period in 2023. We believe MSA's healthy balance sheet and access to significant capital at June 30, 2024, positions us well to navigate through challenging business conditions, supply chain constraints or other unexpected events.

Operating activities. Operating activities provided cash of $104.2 million during the six months ended June 30, 2024, compared to using cash of $190.8 million during the same period in 2023. The improved cash flow from operating activities as compared to the same period in 2023 was primarily related to the prior year contribution of $341.2 million in the divestiture of MSA LLC. Refer to Note 17—Commitments and Contingencies to the unaudited condensed consolidated financial statements in Part I Item 1 of this Form 10-Q for further information. Cash flow provided by operating activities decreased slightly excluding the cash flow impact of the MSA LLC divestiture. Improved operating results were offset by higher cash usage for working capital needs, primarily inventory partially offset by improved accounts payable cash flow as well as higher cash usage for variable compensation payouts and tax prepayments both driven by prior year performance.

Investing activities. Investing activities used cash of $25.5 million during the six months ended June 30, 2024, compared to using $15.6 million during the same period in 2023. The increase in cash used in investing activities as compared to the same period in 2023 was related to increased capital expenditures to support our manufacturing footprint optimization activities. 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 used cash of $67.7 million during the six months ended June 30, 2024, compared to providing cash of $196.6 million during the same period in 2023. During the six months ended June 30, 2024, we had net payments on long-term debt of $13.3 million as compared to net proceeds from long-term debt of $236.9 million during the same period in 2023 to fund the MSA LLC divestiture. Since the MSA LLC divestiture in January 2023, we have paid down $302.3 million of our outstanding borrowings. We paid cash dividends of $38.6 million during the six months ended June 30, 2024, compared to $36.5 million in the same period in 2023. We used cash of $16.8 million during the six months ended June 30, 2024, to repurchase shares, including $10.0 million related to our share repurchase program and the remainder related to our employee stock compensation transactions compared to $3.9 million in the same period in 2023, all of which related to our employee stock compensation transactions.

CUMULATIVE TRANSLATION ADJUSTMENTS

The position of the U.S. dollar relative to international currencies, primarily the euro, at June 30, 2024, resulted in a translation loss of $19.5 million being recorded to the cumulative translation adjustments shareholders' equity account during the six months ended June 30, 2024, compared to a $16.2 million translation gain being recorded to the cumulative translation adjustments shareholders' equity account during the same period in 2023.

COMMITMENTS AND CONTINGENCIES

We made contributions of $2.6 million to our pension plans during the six months ended June 30, 2024. We expect to make total contributions of approximately $5.3 million to our pension plans in 2024 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 June 30, 2024, totaling $10.2 million, of which $1.1 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 June 30, 2024, the Company has $2.0 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 17—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, 2023.

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 $18.9 million or 4.1% and $2.6 million or 3.5%, respectively, for the three months ended June 30, 2024.

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 June 30, 2024, we had open foreign currency forward contracts with a U.S. dollar notional value of $113.6 million. A hypothetical 10% strengthening or weakening of the U.S. dollar would result in a $11.4 million increase or decrease in the fair value of these contracts at June 30, 2024.

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 June 30, 2024, we had $304.1 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 $8.3 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 June 30, 2024, we had $286.3 million of variable rate borrowings. A 100 basis point increase or decrease in interest rates would have a $3.4 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.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company's effective tax rate for the three months ended June 30, 2024, was 23.5%, which differs from the United States of America ("U.S.") federal statutory rate of 21% primarily due to state income taxes. The Company's effective tax rate for the three months ended June 30, 2023, was 23.3%, which differs from the U.S. federal statutory rate of 21% primarily due to state income taxes. The Company's effective tax rate for the six months ended June 30, 2024, was 23.3%, which differs from the United States of America ("U.S.") federal statutory rate of 21% primarily due to state income taxes and nondeductible compensation. The Company's effective tax rate for the six months ended June 30, 2023, was 520.8%, 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—Commitments and Contingencies to the unaudited condensed consolidated financial statements in Part I Item 1 of this Form 10-Q for further information on this transaction. At June 30, 2024, the Company had a gross liability for unrecognized tax benefits of $7.3 million. The Company has recognized tax benefits associated with these liabilities of $0.6 million at June 30, 2024. 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 $0.2 million at June 30, 2024. 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.

Fair Value Measurements	6 Months Ended
Fair Value Measurements	Jun. 30, 2024
Fair Value Disclosures [Abstract]
Fair Value Measurements	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 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 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 was $304.1 million and $312.2 million at June 30, 2024, and December 31, 2023, respectively. The fair value of this debt was $263.9 million and $278.7 million at June 30, 2024, and December 31, 2023, 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.
