Material Weakness in Internal Control over Financial Reporting
A “material weakness,” as defined in Rule 1-02(a)(4) of Regulation S-X, 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 our annual or interim financial statements will not be p…

●We did not design and maintain an effective control environment commensurate with our financial reporting requirements. During the period, we lacked a sufficient number of trained professionals with (i) an appropriate level of accounting knowledge, training and experience to appropriately analyze, …

Risk factors
Text added vs the prior filing · source: 10-Q · 2026-05-11
Other than the amended and additional risk factors set forth below, there were no material changes to the risk factors disclosed in Part II, Item 1A, Risk Factors of our Annual Report on the Form 10-K for the year ended December 31, 2025 as filed with the SEC on March 2, 2026.
The integration of LSI and NuCrypt and the scaling of our Arizona thin-film lithium niobate facility and planned “FAB 2” present significant execution risks.
Realizing the anticipated benefits of the LSI and NuCrypt acquisitions and our capacity expansion depends on successful integration of technology, systems, processes and personnel; achieving required quality and reliability metrics; and timely scaling of production. Integration and scaling activitie…
Failure to execute effectively could delay product roadmaps, increase our cost structure and negatively impact revenue growth and margins.
We depend on certain suppliers to source products. Failure to maintain our relationship with any of these suppliers, or a failure to replace any of these suppliers, could have a material adverse effect on our business, financial position, results of operations and cash flows.

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.
