What Ampco-Pittsburgh does

Ampco-Pittsburgh Corporation, incorporated in Pennsylvania in 1929 and listed on the New York Stock Exchange under ticker AP, is a specialty industrial manufacturer organized into two reporting segments. The Forged and Cast Engineered Products segment, operated through the Union Electric Steel subsidiary, produces forged and cast rolls for global steel and aluminum rolling mills along with ingot and open-die forged products for oil and gas, aluminum, and plastic extrusion customers. The Air and Liquid Processing segment, operating through wholly-owned subsidiaries Aerofin, Buffalo Air Handling, and Buffalo Pumps, manufactures custom finned-tube heat exchanger coils, air handling units, and centrifugal pumps for power generation (including nuclear), the U.S. Navy, pharmaceutical, healthcare, and other industrial markets.

The company makes money by engineering, manufacturing, and selling custom-specification heavy industrial equipment directly to enterprise end-users through a direct field sales force. Pricing is project- and specification-based rather than list-priced, with no public price disclosure. Revenue is generated across two primary verticals: metal production (steel and aluminum rolling mill consumables) and industrial fluid/air handling. The company maintains wholly-owned manufacturing operations in the United States, Sweden, and Slovenia, and participates in China-based manufacturing through joint ventures. Recent corporate actions — including the exit from UK cast roll and steel distribution businesses, a $113.5 million amended credit facility, and a CFO transition — indicate an active portfolio simplification and balance sheet repositioning, while early 2026 order activity grew 38% year-over-year with the Air and Liquid Processing segment up 73%.
