AMPCO PITTSBURGH CORP

GENERAL DEVELOPMENT OF BUSINESS

Ampco-Pittsburgh Corporation (the “Corporation”) was incorporated in Pennsylvania in 1929. The Corporation, individually or together with its consolidated subsidiaries, is also referred to herein as the “Registrant.” The Corporation manufactures and sells highly engineered, high-performance specialty metal products and customized equipment utilized by industry throughout the world. It operates in two business segments – the Forged and Cast Engineered Products (“FCEP”) segment and the Air and Liquid Processing (“ALP”) segment. This segment presentation is consistent with how the Corporation’s chief operating decision maker evaluates financial performance and makes resource allocation and strategic decisions about the business.

For the FCEP segment, global steel manufacturing capacity continues to exceed global consumption of steel products. Demand for steel in the segment’s two largest markets, North America and Europe, softened during 2024 compared to 2023 and 2022 and is approximately 15% below 2019 pre-pandemic levels as of December 31, 2024. The financial impact from weaker demand has been mitigated through higher pricing and increased participation in new mill builds, primarily in North America. Recent order intake has shown improvement, and shipments are expected to increase for the segment’s cast roll facilities and pricing to remain stable in 2025. In addition, forged engineered products (“FEP”) order activity is improving after several years of depressed demand. Increased entry of low-priced products from other countries has negatively impacted local demand in Europe and the U.S., with several of the segment’s largest customers engaging in trade cases to reduce the number of imports into the U.S. In addition, the new administration has announced new tariffs on steel and aluminum imports to the U.S. and has, for now, removed the exceptions that allowed some countries to continue sending products to the U.S.

The primary focus for the FCEP segment is to improve its profitability by maintaining a strong position in the roll market and continuing to improve operational efficiency and equipment reliability following the completion of the previously announced capital equipment program. In addition, in February 2025, the segment's U.K. operations entered into a formal consultation process with its unions and staff to evaluate various options to improve its profitability.

For the ALP segment, businesses are benefiting from steady demand and increased market share but are facing increasing production costs due to inflation and supply chain issues as a result of the lingering effects from a post-pandemic environment. The segment has been implementing price increases for certain of its products to help mitigate these inflationary effects. The focus for this segment is to grow revenues, strengthen engineering and manufacturing capabilities to keep pace with growth opportunities, and continue to improve its sales distribution network.

The Corporation is actively monitoring, and will continue to actively monitor, the lingering effects from a post-pandemic environment, repercussions from the Russia-Ukraine and Middle East conflicts and similar geopolitical matters, economic conditions, and other developments relevant to its business including the potential impact on its operations, financial condition, liquidity, suppliers, industry, and workforce.

NARRATIVE DESCRIPTION OF BUSINESS

Forged and Cast Engineered Products Segment

The FCEP segment produces forged hardened steel rolls, cast rolls and FEP. Forged hardened steel rolls are used primarily in hot and cold rolling mills by producers of steel, aluminum and other metals.

Air and Liquid Processing Segment

The ALP segment includes Aerofin, Buffalo Air Handling and Buffalo Pumps, all divisions of Air & Liquid Systems Corporation (“Air & Liquid”), a wholly owned subsidiary of the Corporation. The segment has operations in Virginia and New York with its headquarters located in Carnegie, Pennsylvania. The segment utilizes an independent group of sales offices located throughout the United States and Canada and has several major competitors.

Aerofin Division of Air & Liquid Systems Corporation produces custom-engineered finned tube heat exchange coils and related heat transfer products for a variety of industries including original equipment manufacturers and commercial, nuclear power generation and industrial manufacturing. It is located in Lynchburg, Virginia.

Buffalo Air Handling Division of Air & Liquid Systems Corporation produces large custom-designed air handling systems for institutional (e.g., hospital, university), pharmaceutical and general industrial building markets. Its primary manufacturing facility is located in Amherst, Virginia with an additional Virginian manufacturing location added in the second half of 2023.

Buffalo Pumps Division of Air & Liquid Systems Corporation manufactures centrifugal pumps for the fossil-fueled power generation, marine defense and industrial refrigeration industries. It is located in North Tonawanda, New York.

Products

In both segments, the products are dependent on engineering, principally custom designed, and are sold to sophisticated commercial and industrial users located throughout the world. Products are delivered directly to the customer via third-party carriers or customer-arranged transportation. For the FCEP segment, one customer accounted for 11% of its net sales in both 2024 and 2023, the loss of which could have a material adverse effect on the segment. For the ALP segment, no customers exceeded 10% of its net sales in 2024 or 2023. For additional information on the products produced and financial information about each segment, see Note 23, Business Segments, to the Consolidated Financial Statements included in Item 8 to this Annual Report on Form 10-K (the “Consolidated Financial Statements”).

Raw Materials

Raw materials used in both segments are generally available from many sources, and neither segment is dependent upon any single supplier for any raw material. Substantial volumes of raw materials used by each segment are subject to significant variations in price. The Corporation’s subsidiaries generally do not purchase or commit for the purchase of a major portion of raw materials significantly in advance of the time they require such materials but periodically make forward commitments for natural gas, electricity and certain commodities (copper and aluminum). See Note 15, Derivative Instruments, to the Consolidated Financial Statements.

Patents and Trademarks

While the Corporation and its subsidiaries hold certain patents, trademarks and licenses, in the opinion of the Corporation, they are not material to either segment.

Backlog

The backlog of orders approximated $378.9 million at December 31, 2024 and 2023, respectively. Backlog for the FCEP segment increased by approximately $2.9 million due to improved order intake for cast rolls offset by lower backlog for forged rolls and lower foreign exchange rates used to translate the backlog of the Corporation’s foreign subsidiaries into the U.S. dollar. Backlog for the ALP segment decreased by approximately $3.0 million year over year with backlog for air handling units and heat exchange coils declining from a year ago offset by improved order intake for centrifugal pumps. Approximately 5% of the backlog is expected to be released after 2025.

Competition

The Corporation faces considerable competition from a large number of companies in both segments. The Corporation believes, however, its subsidiaries are significant participants in each of the niche markets they serve. Competition in both segments is based on quality, service, price, and delivery.

Environmental Protection Compliance Costs

Expenditures for environmental control matters were not material to either segment in 2024 and are not expected to be material in 2025.

Employees and Human Capital Management

Employees

On December 31, 2024, the Corporation and its subsidiaries had 1,634 active employees worldwide (substantially all full-time), of which approximately 56% were employed in the United States. Approximately 31% of the Corporation’s employees are covered by collective bargaining agreements or agreements with works councils.

Oversight

The Compensation Committee of the Board of Directors maintains oversight of the Corporation’s human capital management strategies it may deem important to the long-term sustainability of the Corporation.
