"The team delivered solid organic growth and profit pull-through in the first quarter, resulting in 18% adjusted EPS growth," stated Julie Beck, MSA Safety's Chief Financial Officer. "Our gross margin expansion reflects MBS-driven execution. The balance sheet and free cash flow generation remain strong, and we returned cash to shareholders. We announced a new $500 million share repurchase authorization in February and maintain an active M&A pipeline. Given the solid start to the year and our healthy order book, we are maintaining our mid-single-digit 2026 organic sales growth outlook. We also recognize the potential challenges posed by the volatile geopolitical and macroeconomic operating environment," Ms. Beck added.

The company returned a total of $71 million to shareholders via dividends of $21 million and executing $50 million of share repurchases, while investing $11 million in capital expenditures. MSA maintains a strong liquidity position with net debt at the end of the first quarter of $433 million. The company’s net leverage ratio was 0.9x at March 31, 2026. MSA's strong financial profile, including ample liquidity of $1.2 billion, continues to provide optionality around execution of strategic growth initiatives, including acquisitions.

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

Adjusted operating income, adjusted operating margin, adjusted earnings before interest, taxes, depreciation and amortization (EBITDA) and adjusted EBITDA margin are non-GAAP financial measures and operating ratios derived from non-GAAP measures. Adjusted operating income is defined as operating income excluding currency exchange gains / losses, restructuring charges, acquisition-related amortization, 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. These metrics are consistent with how management 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. 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.

Management believes that adjusted earnings and adjusted diluted earnings per 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.
