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 the unamortized debt issue costs such that total maturities equal the carrying value of long-term debt as of December 31, 2024. The maturities of long-term debt for the periods subsequent to December 31, 2024 are as follows (in millions):
|  |  |  | 2025 |  | 2026 |  | 2027 |  | 2028 |  | 2029 |  | After 2029 |  | Total
|  |  |  | $ | 1,919 |  |  | $ | 1,520 |  |  | $ | 847 |  |  | $ | 740 |  |  | $ | 1,791 |  |  | $ | 6,227 |  |  | $ | 13,044 |
As a result of put provisions associated with certain debt instruments, long-term debt payments due in 2025 include floating rate notes totaling $119 million (classified as current portion of long-term debt). Credit Facilities: 3M has a $4.25 billion five-year revolving credit facility that expires in May 2028. The revolving credit agreement includes a provision under which 3M may request an increase of up to $1.0 billion (at lender’s discretion), bringing the total facility up to $5.25 billion. The credit facility was undrawn at December 31, 2024. Under the $4.25 billion credit facility, the Company is required to maintain its EBITDA to Interest Ratio as of the end of each fiscal quarter at not less than 3.0 to 1. This is calculated (based on amounts defined in the amended agreement) as the ratio of consolidated total EBITDA for the four consecutive quarters then ended to total interest expense on all funded debt for the same period. At December 31, 2024, 3M was in compliance with this requirement. Debt covenants do not restrict the payment of dividends. Other Credit Facilities: The Company also had $0.5 billion in stand-alone letters of credit, bank guarantees, and other similar instruments issued and outstanding at December 31, 2024. These instruments are utilized in connection with normal business activities. Solventum Related Debt: In the first quarter of 2024, Solventum, prior to the Separation discussed in Note 2, issued a total of $8.4 billion in aggregate principal amount of senior unsecured debt and term loans. Also during the first quarter of 2024, Solventum further entered into a revolving credit facility of $2 billion which was undrawn as of March 31, 2024. These Solventum items were guaranteed by 3M until the completion of the Separation on April 1, 2024 and obligations under these notes, loans and facilities became, as transferred obligations, the sole responsibility of Solventum after the Separation. Fixed-to-Floating Interest Rate Swaps: During 2021, 3M entered into interest rate swaps with an aggregate notional amount of $800 million. These swaps converted $500 million and $300 million of 3M’s $1 billion and $650 million principal amount of fixed rate notes due 2049 and 2050, respectively, into floating rate debt for the portion of their terms through mid-2028 with an original interest rate based on a three-month LIBOR index, which since was amended to a rate based on a SOFR index. Long-Term Debt Maturities and Extinguishments: In 2024, 3M repaid $1.1 billion aggregate principal amount of medium-term notes that matured. In 2023, 3M repaid $500 million aggregate principal amount of fixed-rate registered notes that matured, $650 million aggregate principal amount of fixed-rate medium-term notes that matured and 600 million euros aggregate principal amount of fixed-rate medium-term notes that matured. In 2022, 3M repaid 500 million euros aggregate principal amount of fixed-rate medium-term notes that matured and $600 million aggregate principal amount of fixed-rate medium-term notes that matured. Floating Rate Notes: At various times, 3M has issued floating rate notes containing put provisions, amounting to $0.2 billion in total. 3M would be required to repurchase these securities at various prices ranging from 99 percent to 100 percent of par value according to the reduction schedules for each security. Under the terms of this floating rate note due in 2044, holders have an annual put feature at 100 percent of par value from 2014 and every anniversary thereafter until final maturity. Under the terms of the floating rate notes due in 2027, 2040 and 2041, holders have put options that commence ten years from the date of issuance and each third anniversary thereafter until final maturity at prices ranging from 99 percent to 100 percent of par value. For the periods presented, 3M was required to repurchase an immaterial amount of principal on the aforementioned floating rate notes.
