Micron can pay current-quarter investments from operating cash flows, and customer deposits must be accounted for separately

Micron’s operating cash flow for fiscal year $MU 2026 fourth quarter already covers the company’s current-quarter spending on plant and equipment. Customer deposits received additionally increase available funds, but they come with repayment conditions attached. To judge how much more Micron has for capacity expansion or share repurchases, you need to separate cash generated from operations from deposits that are temporarily available.

On September 30, Micron disclosed that for the fourth quarter ended September 3, it generated about $43.97 billion in operating cash flow, while spending $11.11 billion to construct plants and buy equipment. Subtracting the two directly leaves roughly $32.86 billion. This does not add back government subsidies or proceeds from equipment sales, so it differs from the company’s adjusted free cash flow definition.

This quarter, Micron also received $12.3 billion in cash deposits from strategic customer agreements. In the prepared remarks for the earnings call, management made it explicit that these deposits are recorded in financing activities and do not affect free cash flow. The money had not originally flowed into operating cash flow, so deducting it again would underestimate operating performance; including it as “extra money made from selling chips” would overestimate it.

When customers place deposits in advance and agree to multi-year supply arrangements, Micron can receive part of the funds earlier to plan capacity. In the previously disclosed 10-Q for the third quarter, these contract terms set binding purchase quantities, with most using fixed prices or price bands with floors and ceilings. Having purchase volumes written into the contracts provides a higher degree of certainty in arranging capacity than merely relying on forecasts based on customer demand.

This time, management explained that cash deposits under strategic customer agreements are not subject to usage restrictions. After customers meet minimum purchase requirements, they gradually get their deposits back during the latter portion of each agreement. When assessing room for repurchases, dividends, or continued capacity expansion, this obligation must be included as well.

Long-term agreements also cannot guarantee the same amount of operating cash flow every quarter. Even with a price floor, production costs still need to be controlled, deliveries must be completed as agreed, and the timing of cash collections versus accounts payable can all affect cash flow in the quarter. While deposit receipts can ease funding pressure, they cannot replace cash generated by ongoing operations.

If the current-quarter investments are supported by operating cash flow, you still need to calculate how much cash will be left in the future. After the company increases investment, whether operating cash flow remains sufficient and whether deposit repayments clash with other spending will both change the amounts available for repurchases or dividends. Ignoring the deposit repayment obligation would overestimate the funds available for shareholder returns.
