Risk factors
Text added vs the prior filing · source: 10-K · 2026-05-21
We participate in intensely competitive end markets in the global semiconductor industry. Our competitive landscape includes rapid technological change in product design and manufacturing, continuous declines in ASPs, and customers who make purchase decisions based on a mix of factors that vary by c…
market upturn we may not be able to purchase sufficient supplies or components to meet increasing product demand, which could prevent us from taking advantage of opportunities and maximizing our net sales. Any failure to adjust our supply chain volume, secure sufficient supply from third-party vendo…
Our gross margins may be adversely affected by decreases in average selling prices of our products, increases in input costs and shifts in product, customer or channel mix.
The market for our products is generally characterized by declining ASPs, resulting from factors such as increased competition, overcapacity, the amount of inventory held by our customers, the introduction of new products and increased unit volumes. Further, our overall gross margins have fluctuated…
introduction of new products by us or our competitors, or due to other factors, such as customer pricing pressures. To sustain profitable operations, we must continually reduce costs for our existing products and rapidly develop and introduce new products with enhanced features that can be sold init…

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.
