Capital structure and balance-sheet actions

Fiscal 2026 was marked by an active program of debt reduction and equity-linked transactions, largely funded by monetizing the company's retained equity stake in Sandisk Corporation (received in the February 2025 separation of the Flash business):

• February 9, 2026 (accession 0001193125-26-041896): The company satisfied and discharged its 4.750% Senior Notes due 2026 by depositing funds with the trustee on February 5, 2026, following a January 2026 conditional redemption notice.
• February 17, 2026 (accession 0001193125-26-055920, Item 3.03): All outstanding shares of the company's Series A Convertible Perpetual Preferred Stock (issued in a January 2023 private placement) were mandatorily converted into common stock after the stock traded above 150% of the conversion price for the required period.
• February 24, 2026 (accession 0001193125-26-067035): The company filed a Certificate of Elimination retiring the now-unissued Series A Preferred Stock, and separately redeemed in full its 2.850% Senior Notes due 2029 and 3.100% Senior Notes due 2032, depositing redemption funds with the trustee on February 23, 2026 after a February 13, 2026 conditional notice.
• June 2, 2026 (accession 0001193125-26-254621; share count finalized by 8-K/A filed June 8, 2026, accession 0001193125-26-260797): The company entered privately negotiated exchange agreements to retire approximately $858.4 million principal amount of its 3.00% Convertible Senior Notes due 2028 for cash plus new common shares; the amendment disclosed that 21,289,938 shares were delivered in the transactions, which closed on or after June 5, 2026.
• June 11, 2026 (accession 0001193125-26-267514): The company entered exchange agreements with institutional investors to exchange 1,038,681 shares of Sandisk Corporation common stock that it held for shares of the company's own common stock held by those investors, with the exchange expected to close June 22, 2026.
• August 26, 2026 (accession 0001193125-26-365796; share count finalized by 8-K/A filed August 27, 2026, accession 0001193125-26-371309): The company entered further privately negotiated exchange agreements to retire approximately $191.0 million principal amount of its 3.00% Convertible Senior Notes due 2028 for approximately $192.7 million in cash plus new common shares; the amendment disclosed that 4,653,572 shares will be delivered, with closing expected on or after September 2, 2026. Both of these August 2026 filings post-date the company's fiscal 2026 Form 10-K (filed August 14, 2026) and represent the most recent disclosed capital-structure activity.

Together, these actions eliminated the company's 2026, 2029, and 2032 senior notes, retired approximately $858.4 million of its 2028 convertible notes (closed on or after June 5, 2026), and converted all outstanding preferred stock to common equity, materially delevering the balance sheet during fiscal 2026; a further $191.0 million of the 2028 convertible notes was subsequently agreed to be retired in the August 2026 exchange, with closing expected on or after September 2, 2026, after the fiscal year end, adding to the increase in share count driven by the equity components of these exchanges.

M&A and divestitures

No new acquisition, divestiture, or business-combination agreement was signed or closed during the period covered by these filings. Every 8-K, 8-K/A, and earnings release reviewed in this range refers back to the company's completed separation of its Flash business into Sandisk Corporation, which closed on February 21, 2025 (before the current reporting period), as historical background for the "Basis of Presentation" sections of the quarterly results and for the balance-sheet monetization transactions described above under Capital structure. No filing in this range discloses a new deal being signed or closed.
