  1. Modified · Business Momentum

    Our industry has been experiencing unprecedented increases in demand, in particular due to capital expenditures related to AI and other cloud-based applications. As a result, we experienced strong momentum and growth in fiscal 2025 that continued in the first half three quarters of fiscal 2026. As our sales to cloud providers grow, we are seeing a small number of those customers become a larger portion of our business across multiple revenue segments. Our revenue increased by 4037% to $1.61.7 billion in the secondthird quarter of fiscal 2026 as compared to $1.11.2 billion in the secondthird quarter of fiscal 2025, with orders for our products and services significantly exceeding our revenue. This dynamic, together with an industry-wide constrained supply environment, has resulted in historically high backlog. As part of our efforts to secure both long-term supply and demand, we have, and are seeking to continue to, enter into multi-year supply agreements with certain of our suppliers, some of which involve firm purchase commitments and prepayment arrangements, and long-term purchase arrangements with customers.
