Specialized Disclosure Report

Introduction

This Specialized Disclosure Report on Form SD (this “ Report ”) is filed pursuant to Rule 13p-1 promulgated under the Securities Exchange Act of 1934, as amended (the “ Exchange Act ”), for the reporting period from January 1, 2018 to December 31, 2018. This rule requires disclosure of certain information when a company manufactures or contracts to manufacture products for which gold, columbite-tantalite (coltan), cassiterite, wolframite, tantulum, tin and/or tungsten (collectively, the “ Conflict Minerals ”) are necessary to the functionality or production of such products.

Ampco-Pittsburgh Corporation (including its consolidated subsidiaries as the context may require, the “ Corporation ” or the “ Registrant ”) has determined that tin and tungsten (together, the “ Identified Minerals ”) were necessary to the functionality or production of one or more products manufactured by the Corporation or contracted by the Corporation to be manufactured (the “ Covered Products ”) during the period covered by this Report. As such, the Corporation has conducted in good faith a reasonable country of origin inquiry (an “ RCOI ”) to determine whether any of the Identified Minerals in the Covered Products (1) originated in the Democratic Republic of the Congo or any adjoining country (i.e., Angola, Burundi, Central African Republic, the Republic of the Congo, Rwanda, South Sudan, Tanzania, Uganda or Zambia) (the “ Covered Countries ”) or (2) are from recycled or scrap sources.

As discussed more fully below, based on the Corporation’s RCOI, the Corporation has concluded that (a) it does not have any reason to believe that any of the Identified Minerals used in connection with the Covered Products may have originated in a Covered Country or (b) it has reason to believe that the Identified Minerals used in connection with the Covered Products may be from recycled or scrap sources.

The Corporation and its Business Segments

The Corporation was incorporated in Pennsylvania in 1929 and manufactures and sells highly engineered, high performance specialty metal products and customized equipment utilized by industry throughout the world. The Corporation classifies its business in two segments: Forged and Cast Engineered Products and Air and Liquid Processing.

Forged and Cast Engineered Products Segment

The Forged and Cast Engineered Products segment, consisting of Union Electric Steel Corporation and its direct and indirect subsidiaries (collectively, “UES”), has operations in the United States, England, Sweden, Slovenia and Canada and has an equity interest in three joint-venture companies in China. The companies comprising this segment produce ingot, forged products and cast products that service a wide variety of industries globally. The Forged and Cast Engineered Products segment specializes in the production of forged hardened steel rolls used mainly for cold rolling by producers of steel, aluminum and other metals and cast rolls for hot and cold strip mills, medium/heavy section mills and plate mills in a variety of iron and steel qualities. In addition, this segment produces ingot and open-die forged products which are used in the gas and oil industry and the aluminum and plastic extrusion industries.

Air and Liquid Processing Segment

The Air and Liquid Processing segment consists of Aerofin, Buffalo Air Handling and Buffalo Pumps, all divisions of Air & Liquid Systems Corporation, a wholly-owned subsidiary of the Corporation. This segment has operations in Virginia and New York, with headquarters in Carnegie, Pennsylvania, and distributes a significant portion of its products through a common independent group of sales offices located throughout the United States and Canada.

Aerofin produces custom-engineered finned tube heat exchange coils and related heat transfer products for a variety of industries including OEM/commercial, fossil fuel power generation, nuclear power generation and industrial manufacturing.

Buffalo Air Handling produces large custom-designed air handling systems for institutional markets (e.g., hospitals and universities), pharmaceutical markets and general industrial building markets.

Buffalo Pumps manufactures centrifugal pumps for the fossil fuel power generation, marine defense and industrial refrigeration industries.

Reasonable Country of Origin Inquiry

In accordance with the Exchange Act and the rules and regulations thereunder, the Corporation performed an assessment of its product line to examine which of the products manufactured by it or contracted to be manufactured by it contained one or more Conflict Minerals that were necessary for the functionality or production of such identified products. The Corporation concluded that certain of its products contained one or more of the Identified Minerals of tin and tungsten. Consequently, the Corporation conducted in good faith an RCOI with respect to the Identified Minerals in such Covered Products. The purpose of the RCOI was to determine whether any of such Identified Minerals (1) originated in a Covered Country or (2) are from recycled or scrap sources.

After identifying the Covered Products, the Corporation then identified which supplier may have provided materials included in the Covered Products that potentially contained any of the Identified Minerals. The Corporation contacted each of these suppliers and informed them of its obligations with respect to conducting an RCOI and filing this Report pursuant to the Exchange Act. The Corporation also provided each of these suppliers with the most recent due diligence template developed by the Electronic Industry Citizenship Coalition (the “ EICC ”) and the Global e-Sustainability Initiative (the “ GeSI ”), commonly referred to as the Conflict Mineral Report Template (the “ CMRT ”).

The Corporation uses a network of suppliers from numerous countries across multiple continents. The materials sourced from the Corporation’s suppliers are not purchased directly from the smelters where they originated. As such, the Corporation relies on information provided by its suppliers who are, in many cases, themselves sometimes several tiers separated from the smelter at which the original minerals were smelted. The Corporation’s suppliers (many of whom are not subject to the reporting requirements of the Exchange Act) rely on their own suppliers to provide them with information regarding the materials that they source, or they may purchase the materials on the secondary market from recycled or scrap sources.

Once the information was received from suppliers, the Corporation compiled all of the CMRTs and analyzed them individually and compared the smelters and refiners identified in the CMRT supply-chain survey against the list of smelter facilities which have been identified as “conflict free” by programs such as the Conflict-Free Smelter Program of the EICC/GeSI Conflict-Free Sourcing Initiative (the “ CFSI ”).

Results of the Corporation’s Good Faith RCOI and Due Diligence Process

Suppliers & Smelters

In connection with the Corporation’s use of tin and tungsten in Covered Products, a total of 22 suppliers were identified through the Corporation’s due diligence process:

Each of these suppliers reported to the Corporation that the supplied Identified Minerals were (1) not sourced from a Covered Country or (2) originated from recycled or scrap sources.

Despite the Corporation’s best efforts to follow up with certain suppliers, the Corporation did not receive complete and thorough responses from all of them. There are numerous reasons for the Corporation’s inability to receive complete responsiveness from its suppliers and to identify the full supply chain or originating smelter:

As a result, the Corporation has not been able to identify all of the smelters from which its suppliers sourced the Identified Minerals (other than those identified as from recycled or scrap sources). For the Identified Minerals for which the Corporation was able to identify information about the smelter through the relevant supplier, the name and location of that smelter is indicated in the tables below. Because this information is provided by the Corporation’s suppliers, the Corporation cannot be certain that these smelters were in fact in the Corporation’s supply chain.

The Corporation has noted that each of the smelters identified below, other than those marked with an asterisk (the “ Identified Smelters ”), is currently on the conflict-free smelters list published by the CFSI. In addition, each of the Corporation’s suppliers of Identified Minerals sourced from the Identified Smelters has indicated to the Corporation that the applicable Identified Smelter does not source the Identified Mineral from any Covered Country.
