A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of the annual or interim financial statements will not be prevented or detected on a timely basis. During the f…
During the first quarter of fiscal 2026, our management, with the oversight of our audit committee, has initiated steps and plans to take additional measures to remediate the underlying causes of the material weakness, which we currently believe will be primarily through the development and implemen…
Notwithstanding the material weakness, we believe that our financial statements contained in this Quarterly Report on Form 10-Q fairly present our financial position, results of operations and cash flows for the periods covered by this Quarterly Report on Form 10-Q in all material respects.
Other than the foregoing, there were no changes to our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the quarter ended June 30, 2026 that have materially affected, or are reasonably likely to materially affect, our internal cont…

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.
