Long-Term Debt and Short-Term Borrowings

Note 12. Long-Term Debt and Short-Term Borrowings

2024 issuances, maturities, and extinguishments of short- and long-term debt are described in Note 14 to the Consolidated Financial Statements in 3M's 2024 Annual Report on Form 10-K. The Consolidated Statements of Cash Flows include the results of continuing and discontinued operations and, therefore, information regarding similar debt-related activity for 2024 includes activity associated with Solventum through its April 2024 Separation.

The Company had no commercial paper outstanding at September 30, 2025 and December 31, 2024.

In the third quarter and first nine months of 2025, 3M repaid $0.6 billion and $1.8 billion respectively, in aggregate principal amount of primarily fixed-rate unsecured notes that matured.

In the first quarter of 2025, 3M issued $1.1 billion aggregate principal amount of fixed rate unsecured notes. These were comprised of $550 million of 5-year notes due 2030 with a coupon rate of 4.80% and $550 million of 10-year notes due 2035 with a coupon rate of 5.15%.

In 2021, 3M entered into interest rate swaps with an aggregate notional amount of $800 million that converted $500 million and $300 million of 3M’s $1 billion and $650 million principal amount of fixed rate notes due in 2049 and 2050, respectively, into floating rate debt, based on a SOFR index (as subsequently amended) for the portion of their terms through mid-2028. During the third quarter of 2025, 3M terminated half of these fixed-to-floating interest rate swaps, returning $400 million of notes due in 2049 to fixed-rate debt. At the time of termination, a cumulative basis adjustment of $25 million related to the terminated swaps existed on the carrying value of these notes and will be amortized as interest expense over their remaining term.

Future Maturities of Long-term Debt: Maturities of long-term debt in the table below reflect the impact of put provisions associated with certain debt instruments and are net of items such as unamortized debt issue costs such that total maturities equal the carrying value of long-term debt as of September 30, 2025. The maturities of long-term debt for the periods subsequent to September 30, 2025 are as follows (in millions):

Remainder of 2025		2026		2027		2028		2029		2030		After 2030		Total
