Current report
We are subject to securities class action and stockholder derivative litigation, which could result in substantial costs and divert management’s attention.
Current report
The Company and certain of its current and former officers are defendants in a putative securities class action, and certain of the Company’s current and former directors and officers are defendants in a consolidated stockholder derivative action in which the Company is a nominal defendant, each pending in the United States District Court for the Northern District of Illinois. The actions involve allegations of misstatements and omissions concerning, among other things, demand, manufacturing capacity, operating inefficiencies, product mix and gross margins relating to our data center product lines. See Note 11. Commitments and Contingencies. We cannot predict the outcome of these matters. Regardless of outcome, these matters may result in significant legal fees and expenses, including amounts payable under our advancement and indemnification obligations to current and former directors and officers, subject to applicable agreements and law. These costs may not be fully covered by our directors’ and officers’ liability insurance. The litigation may also divert management’s attention, harm our reputation and result in additional claims. An unfavorable outcome or settlement could have a material adverse effect on our financial condition, results of operations and cash flows.
Current report
We have recently experienced significant changes in our senior leadership, which could disrupt our business.
Current report
In May 2026, our former Chief Executive Officer resigned, and our Chief Financial Officer served as interim Chief Executive Officer until the appointment of our current Chief Executive Officer became effective on August 17, 2026. Leadership transitions can disrupt operations, strategy execution, customer relationships and internal controls, and may make it more difficult to retain key employees.
