FOR IMMEDIATE RELEASE

CARNEGIE, PA

May 9, 2022

Carnegie, PA, May 10, 2022 – Ampco-Pittsburgh Corporation (NYSE: AP) (“Ampco-Pittsburgh” or the “Corporation”) reported total net sales of $94.4 million for the three months ended March 31, 2022, compared to $86.8 million for the three months ended March 31, 2021. The increase is primarily attributable to higher sales for the Forged and Cast Engineered Products segment due to higher pricing and surcharges passed through to customers driven by higher raw material, energy and transportation costs, and a higher volume of forged engineered products shipments to the steel distribution and oil and gas markets. This increase was partly offset by a decline in sales in the Air and Liquid Processing segment resulting from supply chain issues impacting the availability of components for production and customer delivery timing.

Commenting on the quarter, Ampco-Pittsburgh’s CEO, Brett McBrayer, said, “We successfully implemented price increases and expanded surcharge coverage in the Forged and Cast Engineered Products segment to address not only raw material price escalation, but also natural gas, electricity and transportation for a large majority of our contracts, which has helped to restore margins. Although we and our customers have been negatively impacted like most manufacturers by supply chain issues affecting availability and lead times for parts, we continue to focus on the controllable elements of our cost structure. We are pleased with the accelerating backlog growth in both segments.”

Income from operations for the three months ended March 31, 2022, was $1.2 million, compared to $0.9 million for the three months ended March 31, 2021. The increase primarily reflects a change in certain employee benefits, which increased income from operations for the current year quarter by $1.4 million, offset, in part, by the impact of unfavorable manufacturing variances from lower production levels, higher raw material, energy and transportation costs in excess of lagging customer pass-throughs, and a lower volume of mill roll, centrifugal pump and custom air handler shipments.

Other – net improved from a year ago, primarily due to foreign exchange gains recorded in the current year quarter compared to losses in the prior year quarter.

Net income was $1.6 million, or $0.08 per diluted share, for the three months ended March 31, 2022, compared to $0.2 million, or $0.01 per diluted share, for the three months ended March 31, 2021.

Mr. McBrayer continued, “While the conflict in Eastern Europe has exacerbated energy cost inflation, particularly for our European facilities, surcharge coverage for natural gas and electricity should help mitigate this headwind in our roll business.”
