• 3Q 2025 GAAP operating income of $1.1 million and net loss of $2.2 million, or $0.11 per share, include non-cash expenses of $3.1 million for accelerated depreciation and other costs related to exiting U.K. cast roll and domestic steel distribution businesses
• Q3 2025 Adjusted EBITDA of $9.2 million up 35% versus prior year
• Q3 2025 Adjusted EPS of $0.04 up $0.14 versus prior year
• Company expects at least $7 to $8 million per year adjusted EBITDA improvement post-U.K. exit

Ampco-Pittsburgh Corporation (NYSE: AP) reported net sales of $108.0 million and $325.4 million for the three and nine months ended September 30, 2025, compared to $96.2 million and $317.4 million for the three and nine months ended September 30, 2024, with sales growth in both segments. Higher shipment volumes in the Air and Liquid Processing segment led the increase, while higher net roll pricing and higher forged engineered products shipments more than offset softer roll shipments in the Forged Engineered Products segment.

The Corporation reported income from operations of $1.1 million and net loss of $2.2 million, or $0.11 per share, for the three months ended September 30, 2025, which included $3.1 million, or $0.15 per share, in accelerated depreciation and other principally non-cash costs associated with the exit from its U.K. cast roll operations and a non-core steel distribution facility. The Corporation expects to have completed the exit from these businesses during the fourth quarter of 2025, after which its consolidated earnings are expected to rise significantly. Income from operations for the nine months ended September 30, 2025 was $1.9 million and net loss of $8.4 million, or $0.42 per share, for the nine months ended September 30, 2025, with exit-related costs of $9.8 million offsetting operational segment results.

Adjusted EBITDA of $9.2 million and $26.0 million for the three and nine months ended September 30, 2025, respectively, improved by $2.4 million and $3.9 million, respectively, compared to the three and nine months ended September 30, 2024, primarily due to higher shipment volumes and margins in the Air and Liquid Processing segment and higher net pricing in the Forged and Cast Engineered Products segment.

Adjusted Earnings Per Share of $0.04 for the three months ended September 30, 2025, exceeded the prior year quarter by $0.14 per share, and rose by $0.16 per share for the nine-months ended September 30, 2025.

Commenting on the quarter, Ampco-Pittsburgh’s CEO, Brett McBrayer, said, “Roll pricing and volume growth at higher margins in the Air and Liquid Processing segment have been key factors in our adjusted EBITDA improvement. While the steel cycle remains sluggish, forged engineered products sales have recently helped to counterbalance. The major headline is that we have taken definitive steps to right-size our operating footprint with demand. In mid-October we accelerated and completed the exit from our U.K. cast roll facility and before the end of the year we expect to complete the exit from a small steel distribution business. In doing so, we will have fundamentally changed the earnings power of our portfolio. We expect $7 to $8 million per full year Adjusted EBITDA improvement following the U.K. exit. As trade policy further clarifies for our steel customers, we are well positioned for sustainable elevated profitability prior to heading into 2026.”

Interest expense of $3.0 million and $8.6 million for the three and nine months ended September 30, 2025, is comparable to interest expense for the three and nine months ended September 30, 2024.

Other income – net for the three months ended September 30, 2025, improved when compared to the three months ended September 30, 2024, due to lower foreign exchange transaction losses, offset in part by lower pension income, but declined for the nine months ended September 30, 2025, due to lower pension income.

The income tax provision for the three and nine months ended September 30, 2025, decreased when compared to the income tax provision for the three and nine months ended September 30, 2024, driven primarily by the benefit of a reduced statutory income tax rate for one of the Corporation's foreign tax-paying entities.

NON-GAAP FINANCIAL MEASURES

The Corporation presents non-GAAP adjusted net income (loss) attributable to Ampco-Pittsburgh, non-GAAP adjusted net income (loss) per share attributable to Ampco-Pittsburgh, non-GAAP adjusted EBITDA and non-GAAP adjusted income (loss) from operations. Non-GAAP adjusted net income (loss) attributable to Ampco-Pittsburgh and non-GAAP adjusted net income (loss) per share attributable to Ampco-Pittsburgh exclude significant charges or credits that are one-time charges or credits, unrelated to the Corporation’s ongoing results of operations, or beyond its control. Non-GAAP adjusted EBITDA is calculated as net loss excluding interest expense, other income - net, income tax provision, depreciation and amortization, and stock-based compensation along with significant charges or credits that are one-time charges or credits, unrelated to the Corporation’s ongoing results of operations, or beyond its control. Non-GAAP adjusted income (loss) from operations is calculated as (loss) income from operations excluding depreciation and amortization and stock-based compensation along with significant charges or credits that are one-time charges or credits, unrelated to the segment’s ongoing results of operations, or beyond its control. During the three and nine months ended September 30, 2025, the non-GAAP financial measures were adjusted to exclude severance and other exit costs (including accelerated depreciation) associated with our exit from U.K. cast roll operations and a non-core steel distribution facility. In addition, for the nine months ended September 30, 2025, the non-GAAP financial measures were adjusted to exclude the benefit resulting from employee-retention credits received. These non-GAAP financial measures are not based on any standardized methodology prescribed by accounting principles generally accepted in the United States of America (“GAAP”).

Beginning in 2025, the Corporation began presenting non-GAAP adjusted EBITDA along with non-GAAP adjusted income (loss) from operations. These measures are key measures used by the Corporation's management and Board of Directors to understand and evaluate the operating performance of the Corporation and its segments. While these non-GAAP measures may not be directly comparable to similarly titled measures presented by other companies, the Corporation's management and Board of Directors believe these non-GAAP measures enhance comparability to companies in its stated industry peer group.

The Corporation believes these non-GAAP financial measures help identify underlying trends in its business that otherwise could be masked by the effect of the items it excludes from adjusted EBITDA and adjusted income (loss) from operations. The Corporation also believes these non-GAAP financial measures provide useful information to management, shareholders and investors, and others in understanding and evaluating its operating results, enhancing the overall understanding of its past performance and future prospects and allowing for greater transparency with respect to key financial metrics used by the Corporation’s management in its financial and operational decision-making. In particular, the Corporation believes the exclusion of the severance and other exit costs and the employee-retention credits can provide a useful measure for period-to-period comparisons of the Corporation’s core business performance.

Non-GAAP adjusted net income (loss) attributable to Ampco-Pittsburgh, non-GAAP adjusted net income (loss) per share attributable to Ampco-Pittsburgh, non-GAAP adjusted EBITDA and non-GAAP adjusted income (loss) from operations are not prepared in accordance with GAAP and should not be considered in isolation of, or as an alternative to, measures prepared in accordance with GAAP. There are limitations related to the use of non-GAAP adjusted net income (loss) attributable to Ampco-Pittsburgh, rather than net loss attributable to Ampco-Pittsburgh, non-GAAP adjusted net income (loss) per share attributable to Ampco-Pittsburgh, rather than net loss per share attributable to Ampco-Pittsburgh, non-GAAP adjusted EBITDA, rather than net (loss) income, or non-GAAP adjusted income (loss) from operations, rather than (loss) income from operations, which are the nearest GAAP equivalents. Among other things, there can be no assurance that additional expenses similar to the severance and other exit costs (including accelerated depreciation) or additional benefits similar to the employee-retention credits will not occur in future periods.
