Recently announced and future U.S. tariffs or other restrictions placed on imports, retaliatory trade measures taken by other countries and resulting trade wars may have a material adverse impact on our results of operations.
In 2025, the U.S. implemented a number of tariffs on goods imported into the U.S., on a country and industry-specific basis (including aluminum, copper and steel). While some of the U.S. Tariffs have been paused, certain U.S. Tariffs are currently in effect, including a base tariff on nearly all imp…

How to read Risk Factors (Item 1A) in a 10-Q
A 10-Q risk-factor section usually takes one of three forms; this page classifies it as one of:
- Pointer — the filer states there have been no material changes and points back to the annual 10-K risk factors; there is no own risk text to compare this quarter.
- Partial update — the filer carves out specific updated risks ("except as set forth below"); the excerpts show exactly what is new this quarter.
- Restated in full — the quarter carries the complete risk-factor text. When the prior quarter was only a pointer there is no prior full text to diff against, so the page flags the section as restated instead.
This describes the filing structure only — it is never a judgement on whether risk went up or down.
