Broadcom files Q3 fiscal 2026 10-Q for quarter ended Aug. 2
Broadcom Inc. filed its quarterly report on Form 10-Q with the SEC on Sept. 10, 2026. The report covers the quarter ended Aug. 2, 2026, and includes year-to-date results for the period from Nov. 3, 2025 through Aug. 2, 2026. Comparative figures are presented for the corresponding periods of fiscal 2025. Broadcom files under Section 13 or 15(d) of the Securities Exchange Act of 1934. The operating structure in the filing is built around two reportable segments: Semiconductor Solutions and Infrastructure Software. Revenue is classified as product revenue or subscriptions and services revenue. The same segment and revenue classifications are used for the prior-year periods, allowing a direct comparison across quarters and nine-month periods. The filing also includes revenue data by geographic region. Selected balance sheet information is included in the filing. Cash and cash equivalents are measured at fair value using Level 1 and Level 2 inputs. Intangible assets are broken out by technology-based assets, customer contracts, trade names, and other intangibles, with in-process research and development captured at the beginning of fiscal 2026. Stockholders' equity activity is shown for common stock, additional paid-in capital, retained earnings, and accumulated other comprehensive income. The debt disclosures cover a wide range of senior notes with maturities from 2025 to 2056. A number of those notes are identified as related to the VMware acquisition. The company also reports term loans due in 2028 and revolver borrowings. Commercial paper balances appear in the same disclosure. These balances are presented as of Aug. 2, 2026, and compared with the balance sheet at Nov. 2, 2025. The filing includes restricted stock unit activity as part of its stock-based compensation disclosures. The officer signature block names Amie Thuener. A subsequent event disclosure describes a quarterly dividend. The dividend was declared on Sept. 1, 2026, with a record date of Sept. 21, 2026, and a payment date of Sept. 30, 2026.

Nvidia to buy Hugging Face for $11.9 billion
Nvidia on Sept. 2 agreed to acquire Hugging Face, the open-source AI model platform, for about $11.9 billion in cash payable to stockholders plus an equity retention program worth up to $1 billion for employees joining Nvidia. The deal is expected to close in the first half of 2027, subject to regulatory approvals. Nvidia said it will keep Hugging Face's platform open, allowing users to upload and download models of their choosing and supporting other chip vendors. In a risk factor filed with the 8-K, Nvidia warned that government restrictions on open-source AI models could hurt Hugging Face's platform and Nvidia's own business, particularly if rules limit models originating from China.
