Nvidia’s Buyback Ambition Faces a Cash-Flow Reality Check

Nvidia’s plan to return as much as $235 billion to shareholders is drawing scrutiny over whether the company’s reported free cash flow reflects the cash truly available for buybacks and dividends.

The questions center on Nvidia’s commitment to return “excess free cash flow” after accounting for “strategic uses.” The company has not changed its stated method for calculating free cash flow, but analysts can arrive at a lower estimate of shareholder-ready cash by treating certain investments and stock-compensation costs differently.

Reported cash flow versus adjusted estimates

Nvidia reported $69.9 billion in free cash flow for the first half of its fiscal year, which ended July 26. A Wall Street Journal analysis adjusted that figure by counting equity investments as spending that competes with shareholder returns.

Nvidia paid $42.4 billion for equity investments during the period and received $7.2 billion from sales, leaving a net outflow of $35.2 billion. Subtracting that from reported free cash flow brings the estimate to about $34.7 billion.

The analysis then deducted another $4.5 billion in taxes withheld when employee shares vested, as well as roughly $9 billion in buybacks used to offset shares issued to employees. On that basis, cash remaining for other uses was about $21.7 billion—approximately 69% below Nvidia’s reported free-cash-flow figure.

These adjustments are not Nvidia’s own reported measure. They reflect an alternative way of assessing how much cash may be available for discretionary spending, including repurchases and dividends.

A demanding buyback pace

Nvidia’s board authorized an additional $150 billion in share repurchases on Sept. 28, bringing the remaining authorization to $235 billion. The company expects to use that authorization through fiscal 2028.

A Barchart analysis estimated that completing the program by January 2028 would require repurchases of about $44 billion per quarter—more than twice Nvidia’s recent pace. Including the dividend, that would amount to roughly $200 billion a year, compared with $126.9 billion in free cash flow over the previous four quarters.

Nvidia Chief Financial Officer Colette Kress has said the company plans to return at least 50% of its free cash flow to shareholders. The company has described its cash generation as allowing it both to invest in technologies and return capital.

Strategic investments complicate the picture

The analysis also points to Nvidia’s growing equity portfolio. The company holds stakes in 13 publicly traded companies and 229 private firms, including OpenAI and Anthropic. Some of those companies are also customers for Nvidia chips.

That overlap has prompted questions about whether Nvidia’s investments are simply separate from its core business—or whether they help finance companies that, in turn, buy Nvidia’s products. The issue has become part of broader debate about the durability of the AI boom and the scale of spending surrounding it.

Nvidia’s long-term debt rose by $24.9 billion during the first half of the fiscal year, reaching $32.4 billion. The Journal analysis said the increase suggests borrowing helped fund some of the buybacks, though the figures alone do not establish how individual funds were used.

Forecasts offer a more optimistic case

Analysts’ projections present a less strained outlook. Forecasts compiled by Visible Alpha put Nvidia’s average free cash flow above $330 billion in fiscal 2028, a level that could theoretically cover the full remaining repurchase authorization.

Nvidia ended the July quarter with $22.44 billion in cash and cash equivalents. The company has also begun listing debt-security and equity-security investments separately in its cash-flow statement, improving investors’ ability to distinguish those activities. By contrast, Microsoft, Amazon and Alphabet report the two categories together.

The central issue is therefore not whether Nvidia has authorized a large buyback, but how much cash will remain for shareholder returns after investments, employee-related costs and other corporate needs are accounted for.
