Enpro Inc. (NYSE:NPO) today announced its financial results for the three months ended March 31, 2024.

"We began the year with strong profitability in Sealing Technologies, and, as expected, continued softness in Advanced Surface Technologies resulting from semiconductor market conditions," said Eric Vaillancourt, President and Chief Executive Officer. "Our disciplined and focused execution across our business continues to deliver outstanding results in a choppy demand environment, demonstrating the resilience of the Enpro portfolio."

Mr. Vaillancourt added, "We're excited about the addition of the AMI business, which closed in late January. Our balance sheet remains healthy, and we have ample flexibility to invest in organic growth opportunities and value-added projects throughout the enterprise, while building our acquisition pipeline of attractive businesses that meet our strategic and financial criteria. We are well-positioned to continue executing on our long-term value creating strategy while delivering critical solutions to our customers."

First Quarter 2024 Consolidated Results

Sales of $257.5 million decreased 8.9% compared to last year. Excluding the impacts of the AMI acquisition and foreign exchange translation, sales declined 11.6% year-over-year. Slower semiconductor markets, as well as weaker demand in commercial vehicle and food and pharmaceutical, more than offset the contribution from pricing actions and strength in nuclear and aerospace markets.

Corporate expenses of $12.2 million in the first quarter of 2024 increased from $11.0 million in the first quarter of 2023. Last year, corporate expense benefited by a favorable $1.9 million mark-to-market valuation of long-term equity incentive plans.

Income from continuing operations was $12.5 million, compared to $26.0 million in the prior-year period. Diluted earnings per share was $0.59, compared to $1.24 in the prior year. The year-over-year change was driven primarily by weakness in the Advanced Surface Technologies (or "AST") segment and an increase in the valuation reserve on a long-term promissory note received in partial consideration for the sale of a non-strategic business in 2020.

Adjusted net income from continuing operations of $33.1 million decreased 18.7% compared to the first quarter of 2023 and adjusted diluted earnings per share from continuing operations decreased 19.5% to $1.57, compared to $1.95 in the prior-year period.

Adjusted EBITDA* of $58.4 million, or 22.7% of total sales, decreased 14.9% compared to the prior-year period driven primarily by results in the AST segment.

First Quarter 2024 Segment Highlights

(All results reflect comparisons to prior-year period unless otherwise noted)

Sealing Technologies - Safeguarding environments with critical applications in diverse end markets

Garlock, STEMCO, and Technetics Group

	Quarters Ended March 31,
(Dollars in millions)	2024	2023	Change
Sales	$171.6	$173.3	(1.0)%
Adjusted Segment EBITDA	$53.0	$49.7	6.6%
Adjusted Segment EBITDA Margin	30.9%	28.7%

Sales decreased 1.0% versus the prior-year period. Excluding the addition of AMI and foreign exchange translation, sales decreased 5.4% as weaker demand in commercial vehicle, general industrial in Asia and food and pharmaceutical was offset in part by pricing gains and strength in nuclear and aerospace.
Adjusted segment EBITDA of $53.0 million was up 6.6% year-over-year, with adjusted EBITDA margins expanding approximately 220 basis points. Excluding the impacts of the acquisition and foreign exchange translation, adjusted segment EBITDA decreased 2.0% compared to the prior-year period. The decrease was driven mainly by lower volume, offset in part by pricing gains, favorable mix and effective cost management.

Advanced Surface Technologies - Leading edge precision manufacturing, coatings, cleaning and refurbishment solutions and innovative optical filter products — NxEdge, Technetics Semi, LeanTeq, and Alluxa

	Quarters Ended March 31,
(Dollars in millions)	2024	2023	Change
Sales	$86.0	$109.4	(21.4)%
Adjusted Segment EBITDA	$17.3	$29.4	(41.2)%
Adjusted Segment EBITDA Margin	20.1%	26.9%

Sales decreased 21.4% versus the prior-year period driven primarily by the current slowdown in semiconductor capital equipment spending and, to a lesser extent, lower sales of optical filter solutions.
Adjusted segment EBITDA decreased 41.2% versus the prior-year period and segment EBITDA margins declined by 680 basis points, driven primarily by the decline in volume.

Balance Sheet, Cash Flow and Capital Allocation

The company generated $6.3 million of cash flow from operating activities of continuing operations during the three months ended March 31, 2024 and $(1.9) million of free cash flow, net of $8.2 million in capital expenditures. This compares to $26.4 million of cash flow from operating activities of continuing operations, or $21.4 million of free cash flow, net of $5.0 million in capital expenditures in the prior year. During the first quarter, the company paid a regular quarterly dividend of $0.30 per share, with dividend payments totaling $6.4 million for the three months ended March 31, 2024.

Enpro ended the first quarter with total debt of $680.1 million and cash of $163.9 million.

Enpro declared a regular quarterly dividend of $0.30 per share on May 2, 2024. The dividend is payable on June 20, 2024 to shareholders of record as of the close of business on June 5, 2024.

2024 Guidance

Enpro continues to expect 2024 revenue growth in the low-to-mid single digit range compared to 2023. Expected adjusted EBITDA and adjusted diluted earnings per share for 2024 remain at $260 million to $280 million and $7.00-$7.80, respectively.

Primary Segment Operating Performance Measure

The primary metric used by management to allocate resources and assess segment performance is adjusted segment EBITDA, which is segment revenue reduced by operating expenses and other costs identifiable with the segment, excluding acquisition and divestiture expenses, restructuring costs, impairment charges, non-controlling interest compensation, amortization of the fair value adjustment to acquisition date inventory, and depreciation and amortization. Segment non-operating expenses and income, corporate expenses, net interest expense, and income taxes are not included in the computation of adjusted segment EBITDA. Under U.S. generally accepted accounting principles ("GAAP"), the primary metric used by management to allocate resources and assess segment performance is required to be disclosed in financial statement footnotes, and accordingly such metric as presented for each segment is not deemed to be a non-GAAP measure under applicable regulations of the Securities and Exchange Commission.

Non-GAAP Financial Information

This press release contains financial measures that have not been prepared in conformity with GAAP. They include adjusted net income, adjusted diluted earnings per share, adjusted EBITDA, adjusted EBITDA margin, total adjusted segment EBITDA and free cash flow. Tables showing the reconciliation of these historical non-GAAP financial measures to the comparable GAAP measures are attached to the release. Adjusted EBITDA and adjusted diluted earnings per share anticipated for full-year 2024 are calculated in a manner consistent with the historical presentation of these measures in the attached tables. Because of the forward-looking nature of these estimates, it is impractical to present quantitative reconciliations of such measures to comparable GAAP measures, and accordingly no such GAAP measures are being presented.

Management believes these non-GAAP metrics are commonly used financial measures for investors to evaluate the company's operating performance and, when read in conjunction with the company's consolidated financial statements, present a useful tool to evaluate the company's ongoing operations and performance from period to period. In addition, these are some of the factors the company uses in internal evaluations of the overall performance of its businesses. Management acknowledges that there are many items that impact a company's reported results and the adjustments reflected in these non-GAAP measures are not intended to present all items that may have impacted these results. In addition, these non-GAAP measures are not necessarily comparable to similarly titled measures used by other companies.

Forward-Looking Statements and Guidance

Statements in this press release that express a belief, expectation or intention, including the 2024 guidance and other statements that are not historical fact, are forward-looking statements under the Private Securities Litigation Reform Act of 1995. They involve a number of risks and uncertainties that may cause actual events and results to differ materially from such forward-looking statements. These risks and uncertainties include, but are not limited to: economic conditions in the markets served by the company's businesses and the businesses of its customers, some of which are cyclical and experience periodic downturns; the impact of geopolitical activity on those markets, including instabilities associated with the armed conflicts in Ukraine and in the Middle East region and any conflict or threat of conflict that may affect Taiwan; uncertainties with respect to the imposition of government embargoes, tariffs and trade protection measures, such as "anti-dumping" duties applicable to classes of products, and import or export licensing requirements, as well as the imposition of trade sanctions against a class of products imported from or sold and exported to, or the loss of "normal trade relations" status with, countries in which the company conducts business, could significantly increase the company's cost of products or otherwise reduce its sales and harm its business; uncertainties with respect to prices and availability of raw materials, including as a result of instabilities from geopolitical conflicts; uncertainties with respect to the company's ability to achieve anticipated growth within the semiconductor, life sciences, and other technology-enabled markets, including uncertainties with respect to receipt of CHIPS Act support and the timing of completion of the new Arizona facility; the impact of fluctuations in relevant foreign currency exchange rates or unanticipated increases in applicable interest rates; unanticipated delays or problems in introducing new products; the impact of any labor disputes; announcements by competitors of new products, services or technological innovations; changes in the company's pricing policies or the pricing policies of its competitors; risks related to the reliance of the AST segment on a small number of significant customers; uncertainties with respect to the company's ability to identify and complete business acquisitions consistent with its strategy and to successfully integrate any businesses that it acquires; and uncertainties with respect to the amount of any payments required to satisfy contingent liabilities, including those related to discontinued operations, other divested businesses and discontinued operations of the company's predecessors, including liabilities for certain products, environmental matters, employee benefit and statutory severance obligations and other matters. Enpro's filings with the Securities and Exchange Commission, including its most recent Form 10-K report, describe these and other risks and uncertainties in more detail. Enpro does not undertake to update any forward-looking statements made in this press release to reflect any change in management's expectations or any change in the assumptions or circumstances on which such statements are based.

Full-year guidance is subject to the risks and uncertainties discussed above and specifically excludes changes in the number of shares outstanding, changes in long-term compensation expense due to changes in the company's common stock price, impacts from future and pending acquisitions, dispositions and related transaction costs, restructuring costs, incremental impacts of tariffs and trade tensions on market demand and costs, and the impact of changes in foreign exchange rates, in each case subsequent to March 31, 2024.

Adjusted Segment EBITDA is total segment revenue reduced by operating expenses and other costs identifiable with the segment, excluding acquisition and divestiture expenses, restructuring and impairment expense, non-controlling interest compensation, amortization of the fair value adjustment to acquisition date inventory, and depreciation and amortization.

Corporate expenses include general corporate administrative costs. Non-operating expenses not directly attributable to the segments, corporate expenses, net interest expense, and income taxes are not included in the computation of Adjusted Segment EBITDA. The accounting policies of the reportable segments are the same as those for the Company.

In 2024, we refined our definition of Adjusted Segment EBITDA and corporate expenses to include certain other income or expenses previously reported in other expense, net. These items were primarily comprised of bank fees and certain foreign exchange transaction gains and losses. As a result of this change, for the quarter ended March 31, 2023, we decreased Advanced Surface Technologies adjusted segment EBITDA by $0.1 million and increased corporate expenses by $0.3 million.

¹Non-controlling interest compensation allocation represents compensation expense adjustment associated with a portion of the rollover equity from the acquisition of Alluxa that was subject to reduction for certain types of employment terminations of the Alluxa sellers and is directly related to the terms of the acquisition. This expense was recognized as compensation expense over the term of the put and call option associated with the acquisition unless certain employment terminations occurred. The Alluxa non-controlling interests were acquired in February 2024.

Management of the Company believes that it would be helpful to the readers of the financial statements to understand the impact of certain selected items on the Company's reported income from continuing operations and diluted earnings per share, including items that may recur from time to time. The items adjusted for in this schedule are those that are excluded by management in budgeting or projecting for performance in future periods, as they typically relate to events specific to the period in which they occur. This presentation enables readers to better compare Enpro Inc. to other diversified industrial technology companies that do not incur the sporadic impact of restructuring activities, costs associated with previously disposed of businesses, acquisitions and divestitures, or other selected items. The adjustments in the table above relate solely to expenses attributable to Enpro Inc. and have been adjusted to remove any amounts attributable to non-controlling interests.

Management acknowledges that there are many items that impact a company's reported results and this list is not intended to present all items that may have impacted these results.

Other adjustments are included in selling, general, and administrative, cost of sales, and other operating expenses on the consolidated statements of operations.

The adjusted income tax expense presented above is calculated using a normalized company-wide effective tax rate excluding discrete items of 25.0%. Per share amounts were calculated by dividing by the weighted-average shares of diluted common stock outstanding during the periods.

²In connection with the sale of GGB, accounted for as a discontinued operation, in the fourth quarter of 2022, we issued an intercompany note between a domestic and foreign entity that is denominated in a foreign currency. As a result of this note, we have recorded losses due to the changes in the foreign exchange rate. The outstanding note is hedged in order to minimize related gains or losses.

³We issued a long-term promissory note in connection to the sale of a divested business. As part of our regular review of the note, in the first quarter of 2024 we concluded a reserve was needed for expected future credit losses. We will continue to monitor the note regularly and make adjustments to the reserve as needed based on known facts and circumstances.
