⚠ Designs Built for One BuyerModerate threat

Cisco Systems (CSCO) — threat to the moat

Cisco is building products for single hyperscaler customers that it says would be difficult to sell to anyone else.

Selling to hyperscalers changes what Cisco builds, and not always safely. Its filing warns that these sales may involve "bespoke product designs and features that would be difficult to sell to alternate customers"1, and that certain committed components are qualified to a specific customer design2.

Provisions for inventory and purchase commitments ($M)819FY24493FY25387FY26Cisco Form 10-K FY2026
Falling, from the last cycle.

Cisco has paid for supply mistakes before. Provisions for inventory and purchase commitments were $819 million in fiscal 2024, $493 million in fiscal 2025 and $387 million in fiscal 20263, the cost of earlier commitments that did not match demand.

The new exposure is larger. Purchase commitments rose to $17,165 million4, and inventory to $5.7 billion5.

The filing is candid that the commitment risk is Cisco's own making. It says "These past efforts and additional purchase commitments and prepayments significantly increased our supply chain exposure, which resulted in negative impacts to our product gross margin"6. Cisco chose to secure supply ahead of demand, and it has paid for that choice before.

The sign to watch is the provision line. If it rises above the fiscal 2024 level of $819 million while hyperscaler orders slow, Cisco will be writing down equipment built for customers who changed their minds.
