Changes in the United States trade environment, including the imposition of import tariffs, has and could adversely affect the amount or timing of our revenue, results of operations or cash flows.
Our business is dependent upon the availability of raw materials and components for assembly.

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.
