Micron expands buyback plan by $33 billion

Micron Technology disclosed in a 10-K filing published Friday that its board approved an additional $33 billion of stock buybacks, lifting the chipmaker’s total authorization to $35.16 billion.

The disclosure, highlighted by CNBC Investing Club in an Oct. 12 article, puts Micron’s authorization at about 3% of its current market capitalization, according to CNBC.

Buyback capacity

The expanded plan is scheduled to take effect Dec. 9, when CNBC said buyback limits tied to the CHIPS Act expire. The CHIPS Act is the U.S.

semiconductor subsidy law that also carries restrictions for participating companies.

A share repurchase authorization allows a company to buy its own stock up to a board-approved ceiling. It does not require Micron to spend the full amount, and the article did not specify a deadline for completing the program.

CNBC said the new authorization roughly matches Micron’s adjusted free cash flow in the fourth quarter of fiscal 2026, which ended in August. The article also cited FactSet estimates for $141 billion of free cash flow over the next four quarters.

The update matters because memory-chip companies often face sharp swings in pricing and capital spending. A larger authorization gives Micron room to return cash if free cash flow holds up, but actual repurchases will depend on management decisions and market conditions.

AI chip read-through

CNBC also said Microsoft announced plans to scale its Azure Maia family of custom accelerators to multi-gigawatt deployments next year. Custom accelerators are in-house chips designed for specific computing workloads, including artificial intelligence.

The article framed the Microsoft move as part of the market debate around Nvidia’s role in AI infrastructure. CNBC said Nvidia customers continue to demand each new generation of its chips because of their computing performance and revenue potential per gigawatt of power.

That point remains an interpretation from CNBC’s market commentary, not a company forecast. The article did not provide an independent estimate of how much Microsoft’s internal silicon may replace Nvidia graphics processors, or when any effect would appear in Nvidia revenue.

Meta Platforms introduced Muse Wonder, which the company said produced state-of-the-art results across benchmarks for personal and professional agents, memory and coding. CNBC said monthly paid subscribers to the Muse personal agent will receive access to the model.

CNBC linked the Meta launch to the company’s $14.3 billion investment in Scale AI, a data-labeling startup. Meta’s benchmark claims were attributed to the company; the article did not include third-party test results.

What to watch

Micron’s expanded authorization is due to become effective on Dec. 9, when CNBC said CHIPS Act buyback restrictions expire. The observable next step is whether the company starts repurchases under the enlarged ceiling.

Before the opening bell on Tuesday, Goldman Sachs, Wells Fargo and Johnson & Johnson are scheduled to report third-quarter results. LSEG estimates cited by CNBC call for Goldman earnings per share of $13.02 on $16.71 billion of revenue, Wells Fargo earnings per share of $1.85 on $22.30 billion of revenue, and Johnson & Johnson earnings per share of $2.54 on $25.28 billion of revenue.

JPMorgan, Citigroup, UnitedHealth Group and Domino’s Pizza are also scheduled to report, according to CNBC. The article said the NFIB Small Business Optimism Index and existing home sales are also due.
