"Our adjusted earnings per share increased by 24%, driven by 6% reported sales growth and robust margin expansion. We also generated strong free cash flow and returned capital to shareholders," stated Julie Beck, MSA Safety's Chief Financial Officer. "Margin expansion was primarily driven by our ongoing execution of the principles of the MSA Business System and benefited from tariff refunds. Our full-year sales outlook includes low-double-digit total revenue growth, supported by mid-single-digit organic growth, a mid-single-digit contribution from acquisitions and a low-single-digit tailwind from foreign exchange," Ms. Beck added.

(more)

The company increased its annual dividend for a 56th consecutive year and returned a total of $47 million to shareholders through $26 million of share repurchases and dividends of $21 million, while investing $13 million in capital expenditures. The company's net leverage ratio was 0.8x at quarter end. Including the debt for the acquisition of Autronica Fire and Security, pro forma net leverage is ~1.8x.

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.

(a)Transaction costs include advisory, legal, accounting, valuation, and other professional or consulting fees incurred during our evaluation of or in connection with acquisitions and divestitures. These costs are included in Selling, general and administrative expense in the unaudited Condensed Consolidated Statements of Income.

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.

Cautionary Statement Regarding Forward-Looking Statements:

Except for historical information, certain matters discussed in this press release may be "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995. These statements relate to future events or our future financial performance and involve various assumptions, known and unknown risks, uncertainties and other factors that may cause our actual results, levels of activity, performance or achievements to be materially different from any future results, levels of activity, performance or achievements expressed or implied by these forward-looking statements. In some cases, you can identify forward-looking statements by words such as “may,” “will,” “should,” “expects,” “intends,” “plans,” “anticipates,” “believes,” “estimates,” “predicts,” “potential” or other comparable words. Actual results, performance or outcomes may differ materially from those expressed or implied by these forward-looking statements and may not align with historical performance and events due to a number of factors, including those discussed in the sections of our annual report on Form 10-K entitled “Cautionary Statement Regarding Forward-Looking Statements” and “Risk Factors,” and those discussed in our Form 10-Q quarterly reports filed after such annual report. MSA’s SEC filings are readily obtainable at no charge at www.sec.gov, as well as on its own investor relations website at http://investors.MSAsafety.com. Although we believe that the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee future results, levels of activity, performance or achievements, and caution should be exercised against placing undue reliance upon such statements, which are based only on information currently available to us and speak only as of the date hereof. We are under no duty to update publicly any of the forward-looking statements after the date of this earnings press release, whether as a result of new information, future events or otherwise, except as required by law.

Non-GAAP Financial Measures:

This press release includes certain non-GAAP financial measures. These financial measures include organic sales change, adjusted operating income, adjusted operating margin, adjusted EBITDA, adjusted EBITDA margin, adjusted earnings, adjusted earnings per diluted share, debt to adjusted EBITDA, and net debt to adjusted EBITDA. 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 also uses these measures internally to assess and better understand our underlying business performance and trends related to core business activities. 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.

(more)

The presentation of these non-GAAP financial measures does not comply with U.S. generally accepted accounting principles ("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. When non-GAAP financial measures are disclosed, the Securities and Exchange Commission's Regulation G requires: (i) the presentation of the most directly comparable financial measure calculated and presented in accordance with GAAP and (ii) a reconciliation of the differences between the non-GAAP financial measure presented and the most directly comparable financial measure calculated and presented in accordance with GAAP. For an explanation of these measures, with a reconciliation to the most directly comparable GAAP financial measure, see the Reconciliation of GAAP Financial Measures to Non-GAAP Financial Measures in the financial tables section above.
