Purchase Commitments vs Inventory in Hardware
Inventory sits on the balance sheet; purchase commitments sit off it and can dwarf it. Filer definitions differ, and write-downs follow a demand drop.

Inventory Is On the Balance Sheet; Commitments Sit Off It
Inventory is stock the company already owns. Purchase commitments are promises to buy inputs under contracts that have not yet become inventory. In a downturn the balance-sheet line is only part of the exposure: the filing can show obligations several times larger, and they still bind if demand collapses.
Filers put those obligations in MD&A, a notes schedule, or a contractual-obligations table. Definitions differ, so a peer column that strips the footnote mixes unlike pools.
Four Filers Side by Side
| Company | Fiscal year | Purchase commitments (as stated) |
|---|---|---|
| Apple | FY2025 | $56.2B manufacturing purchase obligations (MD&A); inventory $5.7B |
| Dell Technologies | FY2026 | $18.8B |
| Cisco Systems | FY2026 | $17.2B (from $7.6B) |
| Arista Networks | FY2025 | $6.8B |
Apple’s $56.2B is the MD&A manufacturing purchase-obligations figure. The notes carry a separate $13.3B of unconditional purchase obligations; those are not the same pool. Inventory was $5,718M at 27 September 2025, shown here as $5.7B. The ratio of those commitments to inventory is about 9.9 times ($56.2B / $5.7B).
Cisco’s purchase commitments rose from $7.6B to $17.2B in FY2026 (filed as up 126%). Arista’s $6.8B includes $6.3B due within a year. Dell’s $18.8B is the sum of the disclosed schedule. Only Apple’s inventory is shown here; the cash-cycle pages carry each filer’s inventory days.
Why the Gap Matters When Demand Drops
A company can report thin inventory days and still be bound to buy wafers, components or assembly capacity for quarters ahead. When end demand falls, two charges often arrive together:
- Inventory already owned is written down to net realisable value.
- Firm purchase commitments force delivery or cancellation costs on volume the company no longer needs.
That sequence is why a negative cash conversion cycle (Negative Cash Conversion Cycles in Hardware) does not erase purchase-commitment risk. Suppliers may fund the on-balance-sheet float while the filing still discloses a large forward buy.
Filer Definitions Are Not Interchangeable
Apple is the clearest warning against a single-column peer table. Manufacturing purchase obligations in MD&A ($56.2B) and unconditional purchase obligations in the notes ($13.3B) are disclosed separately. Adding them, or picking one without a label, changes the ratio to inventory by a wide margin.
Cisco and Arista each publish a commitments figure, and Cisco’s more than doubled year on year. The number is a point-in-time obligation, not a steady-state ratio.
Linking Commitments to Cycle Risk
Purchase commitments scale with expected build. In a product-cycle trough, the same absolute commitment against lower revenue is a heavier burden, and gross margin can compress for reasons that go beyond price (Mid-Cycle Margins for Hardware Companies).
A practical read of a hardware 10-K therefore pairs three items: inventory days from the cash conversion cycle ladder, purchase commitments from MD&A or the notes, and the demand cycle that sized those commitments.
Technology Hardware Sector Primer
The primer places purchase commitments beside inventory so the off-balance-sheet buy-side risk enters the working-capital view of the multi-period model.
- 17 sections, from units, price and the product cycle to working capital in days, mid-cycle margins and a reverse DCF
- 43 pages
- a device brand, a networking maker, a contract manufacturer and a storage maker, all fictional
- 4 worked valuations
- listed hardware makers on filed margins, working-capital days and purchase commitments, each with its fiscal year
- 7-company screen
The Excel model is the primer's product-cycle DCF live across 13 sheets: a device brand, a networking maker, a contract manufacturer and a storage maker, all fictional, plus a column for a company of your own in any of five business-model modes. Revenue is built from trend units, a yearly cycle index and price, with a recurring line on the installed base and an order book for networking; gross margin carries a fixed share of cost of goods, so it rises and falls with the cycle; working capital runs in days; capex funds growth; and the terminal value is struck on mid-cycle cash flow. A reverse DCF reads the margin and the unit growth a price requires, and the sensitivity grids re-run the model in every cell. Change the cycle, the days or the margin and the value moves.

Frequently Asked Questions
- What are purchase commitments in a hardware 10-K?
- Purchase commitments are promises to buy components, manufacturing capacity or other inputs under contracts that are not yet inventory on the balance sheet. Filers disclose them in MD&A, the notes, or a contractual-obligations table, and each filer defines the pool slightly differently.
- How do purchase commitments compare with inventory?
- Inventory is on the balance sheet. Purchase commitments sit off the balance sheet and can be several times larger. Apple FY2025 shows $56.2B of manufacturing purchase obligations in MD&A against $5.7B of inventory; Cisco FY2026 shows $17.2B of purchase commitments.
- Why do write-downs follow a demand drop in hardware?
- When demand falls, inventory already on hand may need a lower carrying value, and firm purchase commitments can force the company to take delivery of components it no longer needs at the old volume. Both paths hit cost of sales or a separate charge.
- Do all hardware filers define purchase obligations the same way?
- No. Apple separates MD&A manufacturing purchase obligations from a smaller unconditional purchase-obligations figure in the notes. Other filers publish a single schedule. Cross-peer tables need each definition labelled beside the number.
