(a) Definition of organic revenue growth provided on the bottom of page eight.

"We closed 2024 with solid performance against the backdrop of a dynamic operating environment," said Steve Blanco, MSA Safety President and Chief Executive Officer. "Our team delivered resilient full year results with double-digit EPS growth and solid operating margin expansion, supported by effective SG A management, despite lower-than-expected sales growth. This year, our sales growth headwinds included pockets of industrial end market weakness, softer U.S. fire service demand and FX. As we enter 2025, we continue to navigate a dynamic operating environment, and we maintain our commitment to achieving our 2028 targets through the execution of our Accelerate corporate strategy, enabled by the MSA Business System.

Financial Highlights

(b) Free cash flow conversion refers to the ratio of free cash flow to adjusted earnings. The free cash flow for the twelve months ended 2023 is adjusted to reflect the divestiture of MSA LLC.

Balance Sheet and Cash Flow

"While the fourth quarter and full year proved to be more volatile than expected, our team's strong operational execution this year delivered resilient results, including continued margin enhancement, double-digit EPS growth, and moderately lower than expected free cash flow conversion. We also made substantial progress on strengthening our financial position and returned cash to shareholders," commented Lee McChesney, MSA Safety Senior Vice President and Chief Financial Officer. While there are macro and geopolitical considerations included in the 2025 outlook, we retain a cautious optimism given our generally healthy operating conditions, solid order pace, and capital deployment flexibility, and we are prepared for a wide array of scenarios, McChesney added.

The company balanced capital allocation priorities in 2024 by returning $79 million of capital to shareholders via dividends, executing $30 million of share repurchases and repaying $94 million in debt. MSA maintains a strong liquidity position with net debt at the end of the fourth quarter of $343 million. The company's net leverage ratio was 0.7x at December 31, 2024. MSA's healthy balance sheet and strong financial profile continue to provide optionality around execution of strategic growth initiatives, including acquisitions.

Reconciliation of GAAP to Non-GAAP Financial Measures

Organic revenue change (Unaudited)

Management believes that organic revenue growth is a useful metric for investors, as foreign currency translation can have a material impact on revenue growth trends. Organic revenue growth highlights ongoing business performance excluding the impact of fluctuating foreign currencies, which is outside of management's control. There can be no assurances that MSA's definition of organic revenue growth is consistent with that of other companies. As such, management believes that it is appropriate to consider revenue growth determined on a GAAP basis in addition to this non-GAAP financial measure.

Adjusted operating income (Unaudited)

Adjusted EBITDA (Unaudited)

Adjusted operating income, adjusted operating margin, adjusted earnings before interest, taxes, depreciation and amortization (EBITDA) and adjusted EBITDA margin are the measures used by management to evaluate segment performance and allocate resources. As such, management believes these measures are useful metrics for investors. Adjusted operating income is defined as operating income excluding restructuring charges, currency exchange gains losses, loss on divestiture of MSA LLC, product liability expense, net cost for product related legal matter, amortization of acquisition-related intangible assets, and transaction costs. Adjusted operating margin is defined as adjusted operating income divided by net sales to external customers. Adjusted EBITDA is defined as adjusted operating income plus depreciation and amortization, and adjusted EBITDA margin is defined as adjusted EBITDA divided by net sales to external customers. Adjusted operating income, adjusted operating margin, adjusted EBITDA and adjusted EBITDA margin are not recognized terms under GAAP, and therefore do not purport to be alternatives to operating income or operating margin as a measure of operating performance. The company's definition of adjusted operating income, adjusted operating margin, adjusted EBITDA and adjusted EBITDA margin may not be comparable to similarly titled measures of other companies. As such, management believes that it is appropriate to consider operating income and net income determined on a GAAP basis in addition to these non-GAAP measures.

Adjusted earnings per diluted share (Unaudited)

(In thousands, except percentages and per share amounts)

Management believes that adjusted earnings and adjusted earnings per diluted share are useful measures for investors, as management uses these measures to internally assess the Company's performance and ongoing operating trends. There can be no assurances that additional special items will not occur in future periods, nor that MSA's definition of adjusted earnings is consistent with that of other companies. As such, management believes that it is appropriate to consider both net income determined on a GAAP basis as well as adjusted earnings.

There can be no assurances that that MSA's definition of debt to adjusted EBITDA and net debt to adjusted EBITDA is consistent with that of other companies.
