In the third and fourth quarters of fiscal 2025, the Company announced restructuring and cost reduction measures, including closure of its Tempe, Arizona wafer fabrication facility, a reduction in headcount at its manufacturing facilities in Oregon, Colorado Springs and the Philippines. In addition, the Company announced 10% reductions in employee headcount across the Company to decrease its operating expenses, and cancellation or modification of its LTSAs with certain wafer foundries.
