Reworded paragraphs (3)
Previous wording
Significant uncertainty exists around the future relationship between the United States and other countries with respect to tariffs and other trade matters. The United States has recently instituted or proposed changes in trade policies that include the renegotiation or termination of trade agreements, the imposition of higher tariffs on imports into the United States, economic sanctions on individuals, corporations or countries, and other government regulations affecting trade between the United States and other countries. In response to these actions, other countries have announced retaliatory tariffs and other trade measures against the United States. We have estimated the effect of the increased tariffs, as they currently stand, could have a $4 million to $8 million impact on our pre-tax profit during 2025 if we are unable to mitigate them, which we intend to do. Mitigation efforts include changing the origin of sourcing materials, sharing of incremental tariff costs with vendors and customer price increases where contractually possible.

We have estimated the effect of the increased tariffs, as they currently stand, could have a $10 million to $14 million impact on our pre-tax profit during the next twelve months if we are unable to mitigate them, which we intend to do. Mitigation efforts include changing the origin of sourcing materials, sharing of incremental tariff costs with vendors and customer price increases where contractually possible.
