Tariff Surcharge, Effective April 16, 2025

Dear Valued Customer,

As you are aware, the U.S. government announced tariffs on a wide range of goods imported
from several countries, including Canada. In response the Government of Canada has
announced reciprocal tariffs. These tariffs are creating increased cost pressures throughout
the supply chain. In response, Henry Company Canada will implement a tariff surcharge to help
offset these impacts.

Effective April 16, 2025, a 5.5% tariff surcharge will be added to all new orders. Any new
orders received on or after this date will include the surcharge.

This surcharge is necessary due to the increased costs tied to global supply chain volatility—
specifically U.S and Canada.-imposed tariffs, as well as ongoing freight and raw material price
fluctuations. We are working actively to reduce the impact of these changes while continuing to
offer the quality and service you rely on.

We understand this may affect your budgeting and planning, and we are providing advance
notice to help you prepare. Please know we are actively working to mitigate the impact of these
tariffs while continuing to deliver high-quality products at competitive prices.

If you have any questions or concerns, please contact your account representative.

We appreciate your continued partnership and the trust you place in Henry Company Canada to
deliver reliable, high-performance building envelope solutions. We remain committed to
supporting your business through these changes and will continue to keep you informed as the
situation evolves.

Sincerely,
