Dear Valued Quaker Houghton Customer

The current Geo-Political conditions throughout the world along with challenging macro-economic
conditions continue to impact our operating costs with higher than expected escalation on raw
materials, packaging, utilities and transportation costs in North America. Raw material and Trucking
availability also remains extremely unpredictable in the region given global supply-demand imbalances,
domestic and international supply chain delays, and ongoing allocations/force majeures from several
large producers in the Chemical Industry.

Effective April 20, 2022, Quaker Houghton is increasing prices across all product lines in the United
States and Canada.
Our decision on the price increase is in light of the significant cost inflation and rising fuel costs have
proven to be more than a temporary market fluctuation.
