AMPCO-PITTSBURGH CORP (AP) 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.

On October 14, 2025, (the “Filing Date”), the Directors of Union Electric Steel UK Limited (“UES-UK”), an indirect wholly owned subsidiary of the Corporation, filed a Notice of Appointment with the High Court of Justice, Business and Property Courts at Leeds (the “Insolvency Court”) formally appointing certain insolvency practitioners of FRP Advisory Trading Limited (“FRP”) as administrators of UES-UK (collectively, the “Administrators”). This action was confined to UES-UK exclusively and did not affect the Corporation or any of its other subsidiaries. As of the Filing Date, UES-UK was in administration and its affairs, business and property were being managed by the Administrators (the “Structured Insolvency”). The Administrators have set out their proposals to UES-UK’s creditors, which include an orderly wind-down of UES-UK’s financial affairs and sale of its assets. In addition, during 2025, the Corporation closed its non-core steel distribution facility located in Ohio previously held by Alloys Unlimited and Processing, LLC (“AUP”). In December 2025, AUP was merged into Union Electric Steel Corporation, a direct wholly owned subsidiary of the Corporation. See Note 2, Exit and Deconsolidation Charges, to the Consolidated Financial Statements included in Item 8 to this Annual Report on Form 10-K (the “Consolidated Financial Statements”) for further information.

For the FCEP segment, global steel manufacturing capacity continues to exceed global consumption of steel products. Demand for steel is soft but stable. In 2025, as a result of low-priced products from other countries entering the United States, tariffs, as outlined under Section 232 of the Trade Expansion Act of 1962, were increased for products with domestic melt and pour requirements imported into the United States. In addition, in the third quarter of 2025, the U.S. government announced new tariffs on coated steel imported into the United States. According to U.S. Census Bureau and U.S. Commerce Department data, imports for 2025 have decreased when compared to 2024 with import reductions accelerating as the year progressed. This should result in increased utilization of our customers' domestic facilities. Similarly, we believe modified tariff and quota systems have been strengthened in Canada and Mexico to support their steel industries, which also should result in better utilization for our customers located in these countries. The primary focus for the FCEP segment for 2026 is to improve its profitability by maintaining a strong position in the roll market and continuing to improve operational efficiency and equipment reliability.

For the ALP segment, businesses are benefiting from increased demand in power generation and U.S. military markets and have successfully increased market share but continue to face increasing production costs due to inflation. The segment has been implementing price increases for its products to help mitigate these inflationary effects. The primary focus for the ALP segment for 2026 is to grow revenues, monitor and minimize inflationary and tariff effects, 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, changes prompted by the U.S. government, repercussions from the 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.

The FCEP segment produces forged hardened steel rolls, cast rolls and forged engineered products (“FEP”). Forged hardened steel rolls are used primarily in hot and cold rolling mills by producers of steel, aluminum and other metals. Cast rolls, which are produced in a variety of iron and steel qualities, are used mainly in hot strip mills, medium/heavy section mills, roughing mills, and plate mills. FEP principally are sold to customers in the steel distribution market, oil and gas industry, and the aluminum and plastic extrusion industries. The segment has operations in the United States, Sweden, Slovenia, and an equity interest in two joint venture companies in China. Collectively, the segment primarily competes with European, Asian, and North and South American companies in both domestic and foreign markets and operates several sales offices located throughout the world.

Union Electric Steel Corporation (“UES”) produces forged hardened steel rolls and FEP. It is headquartered in Carnegie, Pennsylvania, with three manufacturing facilities in Pennsylvania and one in Indiana. The following entities are direct or indirect operating subsidiaries of UES:

Åkers Sweden AB produces cast rolls in a variety of iron and steel qualities for hot strip mills, medium/heavy section mills, roughing mills, and plate mills. It is located in Åkers Styckebruk, Sweden.

Åkers Valji Ravne d.o.o. produces forged rolls for cluster mills and Z-Hi mills, work rolls for narrow and wide strip mills and aluminum mills, back-up rolls for narrow strip mills, and leveling rolls and shafts. It is located in Ravne, Slovenia.

The segment’s two joint venture companies in China include:

Shanxi Åkers TISCO Roll Co., Ltd. is a joint venture between Taiyuan Iron and Steel Co. Ltd. and Åkers AB, a non-operating subsidiary of UES, that produces cast rolls for hot strip mills, steckel mills and medium plate mills. It is located in Taiyuan, Shanxi Province, China. Åkers AB holds a 59.88% interest in the joint venture.

Anhui Baochang Roll Co., Ltd. is a joint venture among UES, Magang (Group) Holding Co., Ltd. and Jiangsu Gong-Chang Roll Co., Ltd. that produces large forged backup rolls for hot and cold strip mills. It is located in Maanshan, Anhui Province, China. Union Electric Steel (Hong Kong) Limited, a non-operating subsidiary of UES, holds a 33% interest in the joint venture.

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 and has a second assembly facility in Virginia.

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.

In both segments, 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 10% of its net sales in 2025 and one customer accounted for 11% of its net sales in 2024. For the ALP segment, one customer accounted for 12% of its net sales in 2025 but no customers exceeded 10% of its net sales for 2024. While the Corporation believes is does not have a significant concentration of sales with any one customer consistently year-to-year, the loss of any of these more significant customers could have a material adverse effect on the respective segment. For additional information on the products produced and financial information about each segment, see Note 24, Business Segments, to the Consolidated Financial Statements.

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. See Note 16, Derivative Instruments, to the Consolidated Financial Statements.

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.

The backlog of orders at December 31, 2025 approximated $328.9 million compared to a backlog of $378.9 million at December 31, 2024. Backlog for the FCEP segment decreased by approximately $41.9 million due to lower order intake for forged and cast rolls offset by higher foreign exchange rates used to translate the backlog of the Corporation’s foreign subsidiaries into the U.S. dollar and improved order intake for FEP. Backlog for the ALP segment decreased by approximately $8.0 million year over year primarily due to

the U.S. Navy’s decision to terminate production of the Constellation Frigate program, which resulted in $7.1 million of orders being removed from backlog toward the latter part of 2025. Costs related to the terminated orders are expected to be paid by the U.S. Navy along with normal profit margins. Approximately 6% of the backlog is expected to be released after 2026.

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. Significant barriers to entry exist in both segments that make it challenging for new competitors to enter into the markets we serve.

Expenditures for environmental control matters were not material to either segment in 2025 and are not expected to be material in 2026.

Employees

On December 31, 2025, the Corporation and its subsidiaries had 1,432 active employees worldwide (substantially all full-time), of which approximately 62% were employed in the United States. Approximately 24% of the Corporation’s employees are covered by collective bargaining agreements.

Oversight

The Compensation Committee of the Corporation's 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.

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.

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. Cast rolls, which are produced in a variety of iron and steel qualities, are used mainly in hot strip mills, medium/heavy section mills, roughing mills, and plate mills. FEP principally are sold to customers in the steel distribution market, oil and gas industry and the aluminum and plastic extrusion industries. The segment has operations in the United States, England, Sweden, Slovenia, and an equity interest in three joint venture companies in China. Collectively, the segment primarily competes with European, Asian, and North and South American companies in both domestic and foreign markets and operates several sales offices located throughout the world.

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.

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.

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

While the Corporation currently is operating at more normal levels, when compared to the operating levels during the pandemic and immediately thereafter, it continues to be challenged by lingering global economic effects of a post-pandemic environment and repercussions from the Russia-Ukraine conflict, among other events, including:

•

Periodic disruptions to the global supply chain for the Corporation, its vendors and its customers;

•

Global inflationary pressures;

•

Depressed business activity in Europe and Asia (specifically China); and

Backlog for the ALP segment increased by approximately $14.5 million and benefited from improved order intake for each of the product lines. Backlog for the FCEP segment decreased by approximately $4.6 million year over year due to lower FEP and cast roll orders partly offset by improved demand and selling prices for mill rolls and higher foreign exchange rates used to translate the backlog of the Corporation’s foreign subsidiaries into the U.S. dollar. Approximately 13% of the backlog is expected to be released after 2024.

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.

Expenditures for environmental control matters were not material to either segment in 2023 and are not expected to be material in 2024.

Employees

On December 31, 2023, the Corporation and its subsidiaries had 1,697 active employees worldwide (substantially all full-time), of which approximately 58% were employed in the United States. Approximately 31% of the Corporation’s employees are covered by collective bargaining agreements or agreements with works councils.

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.

While the Corporation operated at normal levels in 2022, it continues to be challenged by lingering global economic effects of a post-pandemic environment and repercussions from the Russia-Ukraine conflict, including:

•

Periodic disruptions to the global supply chain for the Corporation, its vendors and its customers,

•

Global inflationary pressures,

•

European energy crisis, and

•

Delays in receiving and shipping product due to lack of transportation.

The Corporation is actively monitoring, and will continue to actively monitor, the geopolitical and economic consequence of these events and the potential impact on its operations, financial condition, liquidity, suppliers, industry, and workforce.

The FCEP segment produces forged hardened steel rolls, cast rolls and forged engineered products (“FEP”). Forged hardened steel rolls are used primarily in hot and cold rolling mills by producers of steel, aluminum and other metals. Cast rolls, which are produced in a variety of iron and steel qualities, are used mainly in hot strip mills, medium/heavy section mills, roughing mills, and plate mills. FEP principally are sold to customers in the steel distribution market, oil and gas industry and the aluminum and plastic extrusion industries. The segment has operations in the United States, England, Sweden, Slovenia, and an equity interest in three joint venture companies in China. Collectively, the segment primarily competes with European, Asian and North and South American companies in both domestic and foreign markets and distributes a significant portion of its products through sales offices located throughout the world.

Union Electric Steel Corporation (“UES”) produces forged hardened steel rolls and FEP. It is headquartered in Carnegie, Pennsylvania, with three manufacturing facilities in Pennsylvania and one in Indiana. The following entities are direct or indirect operating subsidiaries of UES:

Union Electric Steel UK Limited produces cast rolls in a variety of iron and steel qualities for hot strip mills, medium/heavy section mills and plate mills. It is located in Gateshead, England.

Åkers Sweden AB produces cast rolls in a variety of iron and steel qualities for hot strip mills, medium/heavy section mills, roughing mills, and plate mills. It is located in Åkers Styckebruk, Sweden.

Åkers Valji Ravne d.o.o. produces forged rolls for cluster mills and Z-Hi mills, work rolls for narrow and wide strip and aluminum mills, back-up rolls for narrow strip mills, and leveling rolls and shafts. It is located in Ravne, Slovenia.

Alloys Unlimited Processing, LLC is a distributor of tool steels and alloys and carbon round bar. It is located in Austintown, Ohio.

The segment’s three joint venture companies in China include:

Shanxi Åkers TISCO Roll Co., Ltd. is a joint venture between Taiyuan Iron and Steel Co. Ltd. and Åkers AB, a non-operating subsidiary of UES, that produces cast rolls for hot strip mills, steckel mills and medium plate mills. It is located in Taiyuan, Shanxi Province, China. Åkers AB holds a 59.88% interest in the joint venture.

Anhui Baochang Roll Co., Ltd., previously known as Magong Gongchang United Rollers Co., Ltd., is a joint venture among UES, Magang (Group) Holding Co., Ltd. and Jiangsu Gong-Chang Roll Co., Ltd. that produces large forged backup rolls for hot and cold strip mills. It is located in Maanshan, Anhui Province, China. Union Electric Steel (Hong Kong) Limited, a non-operating subsidiary of UES, holds a 33% interest in the joint venture.

Jiangsu Gong-Chang Roll Co., Ltd. is a joint venture that produces cast rolls for hot strip mills, medium/heavy section mills and plate mills. It is located in Xinjian Town Yixing City, Jiangsu Province, China. Union Electric Steel UK Limited holds a 24.03% interest in the joint venture.

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 headquarters in Carnegie, Pennsylvania. The segment distributes a significant portion of its products through a common independent group of sales offices located throughout the United States 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 OEM/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. It is located in Amherst, Virginia.

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.

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 10% of its net sales in 2022, the loss of which could have a material adverse effect on the segment, and no customers exceeded 10% of its net sales in 2021. For the ALP segment, no customers exceeded 10% of its net sales in 2022 or 2021. For additional information on the products produced and financial information about each segment, see Note 17, Revenue, and Note 24, Business Segments, to the Consolidated Financial Statements.

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.

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.

The backlog of orders at December 31, 2022 was approximately $369.0 million compared to a backlog of $292.6 million at year-end 2021. Both segments contributed to the improvement in backlog. Backlog for the FCEP segment increased by approximately $28.8 million year over year due to the net of improved demand and sale price increases for mill rolls offset by lower FEP backlog and foreign exchange rates used to translate the backlog of the Corporation’s foreign subsidiaries into the U.S. dollar. Backlog for the ALP segment increased by approximately $47.6 million and benefited from improved order intake for each of its product lines. Approximately 6% of the backlog is expected to be released after 2023.

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

Expenditures for environmental control matters were not material to either segment in 2022 and are not expected to be material in 2023.

Employees

On December 31, 2022, the Corporation and its subsidiaries had 1,565 active employees worldwide (substantially all full-time), of which approximately 54% were employed in the United States. Approximately 34% of the Corporation’s employees are covered by collective bargaining agreements or agreements with works councils.

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.

On January 30, 2020, the World Health Organization (“WHO”) announced a global health emergency caused by a new strain of the coronavirus (“COVID-19”) and advised of the risks to the international community as the virus spread globally. In March 2020, the WHO classified the COVID-19 outbreak as a pandemic based on the rapid increase in exposure globally. In response, many state and local governments required the closure of various businesses. The U.S. Department of Homeland Security, however, issued guidance outlining criteria to identify domestic businesses as operating in critical infrastructure industries, essential to the economic prosperity, security and continuity of the United States, which provides exceptions to certain closures mandated by state and local governments and permits businesses to continue operations during such an order. The Corporation’s domestic businesses were, and continue to be, deemed to participate in critical infrastructure industries; however, despite the designation and particularly in 2020, the Corporation has had to periodically and temporarily idle certain operations of its FCEP segment and, consequently, furlough certain of its employees in response to market conditions. While most of these direct impacts were experienced in 2020, as variants have developed, the Corporation has experienced episodic disruptions to its operations or the operations of its customers and suppliers. The pandemic also has spurred disruptions to the global supply chain, which is believed to be a key factor in the global inflationary pressures of 2021. Accordingly, the Corporation has experienced, and may continue to experience, customer-requested delays of deliveries or cancellation of orders, lower order intake resulting from customers postponing projects, inability to obtain raw materials and supplies critical to the manufacturing process, delays in receiving and shipping product due to the lack of transportation, and higher cost of production and transportation.

Air and Liquid Processing Segment

The Air and Liquid Processing 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 headquarters in Carnegie, Pennsylvania. It distributes a significant portion of its products through a common independent group of sales offices located throughout the United States and Canada and has several major competitors.

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, and is located in Amherst, Virginia.

Buffalo Pumps Division of Air & Liquid Systems Corporation manufactures centrifugal pumps for the fossil fueled power generation, marine defense and industrial refrigeration industries, and 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 additional information on the products produced and financial information about each segment, see Note 17, Revenue, and Note 24, Business Segments, to 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 do make forward commitments for 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 at December 31, 2020, was approximately $246 million compared to a backlog of $321 million at year-end 2019. The reduction in backlog is attributable to the FCEP segment due to customers postponing order placement given the uncertainty surrounding the COVID-19 pandemic and several of the FCEP segment’s largest customers adjusting their ordering patterns. The reduction is not a reflection of any loss of market share. Approximately 8% of the backlog is expected to be released after 2021.

Competition

The Corporation faces considerable competition from a large number of companies in both segments. The Corporation believes, however, that its subsidiaries are significant participants in each of the niche markets that 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 2020 and are not expected to be material in 2021.

Employees and Human Capital Management

Employees

On December 31, 2020, the Corporation and its subsidiaries had 1,533 active employees worldwide, of which approximately 50% are employed in the United States and approximately 50% are outside the United States. Approximately one-third of the Corporation’s employees are covered by collective bargaining agreements or works councils.

Oversight

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

Key Areas of Focus for the Corporation

Health and Safety – The Corporation’s health and safety program is designed around the regulations associated with the specific hazards and unique working environments of the Corporation’s manufacturing and headquarter operations. The Corporation requires all of its locations to perform regular safety audits to ensure compliance with the safety program. Leading indicators, such as reporting and training of all near-miss events, are used to identify risks for potential future incidents. Lagging indicators, such as OSHA recordable rates and lost time incidence rates, are used to measure achievement of safety metrics, both of which statistically improved in 2020 over 2019.

Diversity and Inclusion – The Corporation tracks various metrics such as turnover, absenteeism and diversity. The Corporation has developed strategies to ensure that employees of diverse backgrounds and perspectives enjoy a culture of mutual respect, inclusiveness and teamwork in an environment which values diversity.

For additional information on the products produced and financial information about each segment, see Note 21 (Business Segments) of this Annual Report on Form 10-K.

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 do make forward commitments for the supply of natural gas and certain commodities (copper and aluminum). See Note 13 (Derivative Instruments) of this Annual Report on Form 10-K.

Patents and Trademarks

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

Backlog

The backlog of orders at December 31, 2017, was approximately $326 million, compared to a backlog of $234 million at year-end 2016. Approximately 6% of the backlog is expected to be released after 2018.

Competition

The Corporation faces considerable competition from a large number of companies in both segments. The Corporation believes, however, that its subsidiaries are significant participants in each of the niche markets which they serve. Competition in both segments is based on quality, service, price and delivery. For additional information, see Part I, Item 1 “General Development of Business” of this Annual Report on Form 10-K.

As part of an overall strategy to develop new markets and maintain a leadership position in each of the industry niches served, the Corporation’s subsidiaries in both segments incur expenditures for research and development. The activities that are undertaken are designed to develop new products, improve existing products and processes, enhance product quality, adapt products to meet customer specifications and reduce manufacturing costs. In the aggregate, these expenditures approximated $3.39 million in 2017, $2.72 million in 2016 and $1.14 million in 2015.

Environmental Protection Compliance Costs

Expenditures for environmental control matters were not material to either segment in 2017 and are not expected to be material in 2018.

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 classifies its businesses in two segments: Forged and Cast Engineered Products and Air and Liquid Processing.

On March 3, 2016, the Corporation acquired the stock of Åkers AB and certain of its affiliated companies, including Åkers AB’s 60% equity interest in a Chinese joint venture company (collectively, “Åkers”) from Altor Fund II GP Limited. The acquired companies, now part of the Forged and Cast Engineered Products segment, added roll production facilities in Sweden, the United States, Slovenia, and China, a number of sales offices, and a service capability in the United States. The acquisition enables cast roll production in the United States, forged roll production in Europe, and a low-cost product alternative for customers.

On November 1, 2016, the Corporation acquired the stock of ASW Steel Inc. (“ASW”), a premier specialty steel producer based in Welland, Ontario, Canada, from CK Pearl Fund, Ltd., CK Pearl Fund LP, and White Oak Strategic Master Fund, L.P. The acquisition provides the Forged and Cast Engineered Products segment of the Corporation with the capabilities to manufacture the additional chemistries needed to expand the reach into the open-die forging market.

FINANCIAL INFORMATION ABOUT SEGMENTS

The sales and operating results of the Corporation’s two segments and the identifiable assets attributable to both segments for the three years ended December 31, 2016 are set forth in Note 21 (Business Segments) of this Annual Report on Form 10-K.

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”.

In 2013, the Forged and Cast Rolls segment recognized a need to diversify its product offerings and started producing non-roll products - primarily ingot and open die forged products which are used in the gas and oil industry and the aluminum and plastic extrusion industries. As the demand for the non-roll product has grown, we determined that Forged and Cast Engineered Products is a more appropriate segment name and have reflected that change throughout this Annual Report on Form 10-K.

The Corporation classifies its businesses in two segments: Forged and Cast Engineered Products and Air and Liquid Processing.

FINANCIAL INFORMATION ABOUT SEGMENTS

The sales and operating profit of the Corporation’s two segments and the identifiable assets attributable to both segments for the three years ended December 31, 2014 are set forth in Note 19 (Business Segments) on page 53 of this Annual Report on Form 10-K.

It is located in Gateshead, England and is a major supplier of cast rolls to the metalworking industry worldwide. It primarily competes with European, Asian and North and South American companies in both the domestic and foreign markets. Union Electric Steel UK also has an investment in a Chinese producer of cast rolls.

Air and Liquid Processing Segment

Aerofin Division of Air & Liquid Systems Corporation produces finned tube and plate finned heat exchange coils for the commercial and industrial construction, process and utility industries and is located in Lynchburg, Virginia.

Buffalo Air Handling Division of Air & Liquid Systems Corporation produces large custom air handling systems used in commercial, institutional and industrial buildings and is located in Amherst, Virginia.

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

All three of the divisions in this segment are principally represented by a common independent sales organization and have several major competitors.

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.

The Forged and Cast Rolls segment has one international customer which constituted approximately 12% of its sales in 2010. The loss of this customer would not be expected to have a significant adverse financial impact on the segment.

For additional information on the products produced and financial information about each segment, see page 4 and Note 19 (Business Segments) on page 51 of this Annual Report on Form 10-K.

ampco pittsburgh | 2010 annual report 6

Raw Materials

Raw materials used in both segments are generally available from many sources and the Corporation is not dependent upon any single supplier for any raw material. Substantial volumes of raw materials used by the Corporation are subject to significant variations in price. The Corporation generally does not purchase or commit for the purchase of a major portion of raw materials significantly in advance of the time it requires such materials but does make substantial forward commitments for the supply of natural gas.

Patents

While the Corporation holds some patents, trademarks and licenses, in the opinion of management they are not material to either segment of the Corporation’s business, other than in protecting the goodwill associated with the names under which products are sold.

Backlog

The backlog of orders at December 31, 2010 was approximately $397 million compared to a backlog of $501 million at year-end 2009. In addition, certain companies in the Forged and Cast Rolls group have long-term supply agreements under which certain customers are committed to purchasing approximately $50 million (through 2014) of product for which specific orders have not yet been received. To better match the changing production levels of their customers, backlog remains subject to rescheduling including, in some situations, bringing forward orders previously deferred. Accordingly, it is difficult to predict accurately the proportion of backlog to ship in 2011 and thereafter; however, based on current estimates, approximately $137 million is expected to be released after 2011.

Competition

The Corporation faces considerable competition from a large number of companies in both segments. The Corporation believes, however, that it is a significant factor in each of the niche markets which it serves. Competition in both segments is based on quality, service, price and delivery. For additional information, see “Narrative Description of Business” on page 6 of this Annual Report on Form 10-K.

Research and Development

As part of an overall strategy to develop new markets and maintain leadership in each of the industry niches served, the Corporation’s businesses in both segments incur expenditures for research and development. The activities that are undertaken are designed to develop new products, improve existing products and processes, enhance product quality, adapt products to meet customer specifications and reduce manufacturing costs. In the aggregate, these expenditures approximated $1.71 million in 2010, $1.35 million in 2009 and $1.35 million in 2008.

Environmental Protection Compliance Costs

Expenditures for environmental control matters were not material to either segment in 2010 and such expenditures are not expected to be material in 2011.

Employees

On December 31, 2010, the Corporation had 1,264 active employees.

The backlog of orders at December 31, 2008 was approximately $691 million compared to a backlog of $729 million at year-end 2007. In addition, the Corporation is a party to long-term supply agreements under which certain customers are committed to purchasing (in 2010 and 2011) approximately $72 million of product for which specific orders have not yet been received. As a result of the severe economic downturn and the reduction in the level of steel output, the Corporation is negotiating deferment of roll deliveries with customers to better meet their production requirements. Therefore it is not possible to accurately determine in which year shipments will be made.

The Corporation faces considerable competition from a large number of companies in both segments. The Corporation believes, however, that it is a significant factor in each of the niche markets which it serves. Competition in both segments is based on quality, service, price and delivery.
