Profit isn't the same as cash
A company can report a profit and still see cash leave — if it spends that money buying inventory or waiting to be paid by customers. 'Operating cash flow' shows what actually hit the bank. When it's deeply negative, the company has to fund itself some other way.

Operating cash flow / working capital
Supermicro's profit was positive but its cash flow was *minus $6.6B* — a sign of how much it's stretching to chase AI demand.

-$6.6
B
Operations used $6.6B of cash in the quarter — despite a reported profit. The money went into inventory and unpaid customer bills, not the bank.

Where did the cash go? Mostly into a warehouse. To be ready for AI orders, Supermicro stockpiled components — chips, boards, parts. That inventory more than doubled in nine months. It's a bet: if the orders arrive, the inventory turns into sales. If demand cools or chip prices drop, it becomes a costly pile of aging parts.
The bet · inventory
$11.1
B
Inventory swelled to $11.1B (from $4.7B nine months earlier) — a huge wager on parts ahead of orders, and the main reason cash drained away.
With cash flowing out, Supermicro funded the gap by borrowing. That leaves it in a very different spot from its cash-rich peers: a thin cash cushion against meaningful debt, in a business that eats cash to grow. The balance sheet is the soft spot.
The cushion · cash vs debt
$1.3
B
Just $1.3B of cash against about $8.8B of bank debt and convertible notes — a thin cushion for a company burning cash to grow.
