If we fail to implement our business strategy successfully, our financial performance could be harmed.

We have not been historically profitable, which may recur in the future. Our operating results may fluctuate significantly from quarter to quarter and may fall below expectations in any particular fiscal quarter.
We were profitable in fiscal 2024, however, we have recorded net losses for the prior three fiscal years. We may not be profitable in fiscal 2025 or future years. While we achieved profitable results in fiscal 2024, we cannot be certain that we will sustain profitability in future years.
There remains uncertainty in our business, which makes it difficult to evaluate our business and future prospects. In addition, our operating results historically have been difficult to predict and have at times fluctuated from quarter to quarter due to a variety of factors, many of which are outsid…
Our operating expenses do not always vary directly with revenue and may be difficult to adjust in the short term. As a result, if revenue for a particular quarter is below our expectations, we may not be able to proportionately reduce operating expenses for that quarter, and therefore such a revenue…
While we generated positive operating cash flow in fiscal 2024 and the prior year, we have a history of negative operating cash flows, and we may require additional financing in the future, which may not be available to us.

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.
