2.70% Senior Notes - On March 18, 2021, we issued $400 million aggregate principal amount of 2.70% senior notes due 2031 at an issue price of 98.763%. The 2.70% senior notes are general unsecured senior obligations and rank equally with our other unsecured senior indebtedness. The offer and sale of the notes were registered under the Securities Act of 1933, as amended. We incurred financing costs in 2021 of approximately $4 million related to the 2.70% senior notes, which are being amortized over the term of the notes.
The indenture governing the 2.70% senior notes includes certain customary covenants that, among other things and subject to certain qualifications and exceptions, limit our ability and the ability of our subsidiaries to:
•grant liens to secure indebtedness;
•engage in sale and lease back transactions;
•merge or consolidate with, or convey, transfer or lease all or substantially all of our assets to a third party.
We were in compliance with all covenants under the indenture governing the 2.70% senior notes as of December 31, 2025 and December 31, 2024.
3.78% Senior Notes - On January 4, 2017, we issued $250 million in senior unsecured notes in a private placement with The Prudential Insurance Company of America and certain other purchasers. These notes bear interest at 3.78% with interest payable semiannually. We have made two principal payments of $50 million each on January 4, 2025 and January 5, 2026. We have three remaining principal payments of $50 million due January 4 of each year through 2029. We have the right to make optional prepayments on the notes at any time, subject to certain limitations. The note purchase agreement contains representations, warranties, terms, and conditions customary for transactions of this type. These include negative covenants, certain financial covenants, and events of default which are substantially similar to the covenants and events of default in our revolving credit facility.
We were in compliance with all covenants under the 3.78% senior notes as of December 31, 2025 and December 31, 2024.
Term Loan - On January 22, 2024, we entered into a credit agreement for an unsecured $250 million term loan (the Term Loan Credit Agreement), which had a maturity date of January 22, 2026. We borrowed the entire $250 million available under the Term Loan Credit Agreement and paid financing costs of $0.4 million, which were amortized over the term that the principal was outstanding under the agreement. We were required to repay the principal amount borrowed under the term loan in full at maturity. Subject to the conditions set forth in the Term Loan Credit Agreement, we had the option to prepay, without penalty, amounts borrowed under the term loan, together with any accrued and unpaid interest, prior to maturity. Any amounts prepaid prior to maturity were not available for additional borrowings by us. We repaid the Term Loan Credit Agreement in full during 2025 and there are no remaining obligations related to the loan as of December 31, 2025.
The principal amount borrowed under the term loan bore interest at a variable rate equal to Term SOFR plus the Applicable Rate. The Applicable Rate was based, at our option, on either our Leverage Ratio or Ratings Level. All capitalized terms are as defined in the Term Loan Credit Agreement.
The Term Loan Credit Agreement contained certain customary covenants, including financial covenants, which required us to maintain a consolidated Leverage Ratio (as defined in the Term Loan Credit Agreement) of no more than 3.75 to 1.00 except during an Increased Leverage Period (as defined in the Term Loan Credit Agreement). We were in compliance with all covenants under the term loan at the time we repaid it in 2025 and as of December 31, 2024.
Revolving Credit Facility - On January 22, 2024, we entered into a credit agreement for a $900 million revolving credit facility (the Revolving Credit Agreement). The revolving credit facility matures on January 22, 2029 and includes a $500 million sublimit for multicurrency borrowings, an initial letter of credit sublimit of $25 million, and a $20 million sublimit for swingline loans. The Revolving Credit Agreement includes an expansion feature allowing us, subject to certain conditions, to request an increase in the aggregate amount of the revolving credit facility or obtain incremental term loans in an amount up to $450 million. We may also request an extension of the maturity date as provided for in the Revolving Credit Agreement. Certain of our foreign subsidiaries may, from time to time, become borrowers under the Revolving Credit Agreement. The obligations under the Revolving Credit Agreement are unsecured and are fully and unconditionally guaranteed by NewMarket.
Concurrently with entering into the Revolving Credit Agreement, we terminated our former revolving credit facility entered into on March 5, 2020. Upon termination, we repaid the amount then outstanding under the former revolving credit facility, plus accrued and unpaid interest.
Borrowings made under the revolving credit facility bear interest at a variable rate determined, at our option, at an annual rate equal to (i) the Base Rate, (ii) Term SOFR, (iii) the Weekly Adjusted Term SOFR, (iv) the Alternative Currency Term Rate, or (v) the Alternative Currency Daily Rate, each plus the Applicable Rate and all as defined in the Revolving Credit Agreement. The Applicable Rate is based, at our option, on either our Leverage Ratio or Ratings Level. All capitalized terms are as defined in the Revolving Credit Agreement.
We paid financing costs in 2024 of approximately $1.8 million related to this revolving credit facility and carried over deferred financing costs from the former revolving credit facility of approximately $0.4 million, resulting in total gross deferred financing costs of $2.2 million, which we are amortizing over the term of the Revolving Credit Agreement.
Outstanding borrowings under the revolving credit facility amounted to $288 million at December 31, 2025 and $77 million at December 31, 2024. Outstanding letters of credit amounted to approximately $4 million at both December 31, 2025 and December 31, 2024. The unused portion of the revolving credit facility amounted to $608 million at December 31, 2025 and $819 million at December 31, 2024.
The average interest rate for borrowings under the applicable revolving credit agreement was 5.3% during the year ended December 31, 2025 and 6.5% during the year ended December 31, 2024.
The Revolving Credit Agreement contains certain customary covenants, including financial covenants, which require us to maintain a consolidated Leverage Ratio (as defined in the Revolving Credit Agreement) of no more than 3.75 to 1.00 except during an Increased Leverage Period (as defined in the Revolving Credit Agreement). We were in compliance with all covenants under the revolving credit facility as of December 31, 2025 and December 31, 2024.Historical Timeline

About Debt Disclosures
Debt disclosures detail a company's borrowing structure — the types of instruments, interest rates, maturity schedule, and covenant restrictions that define its financial obligations and flexibility. This section is essential for assessing refinancing risk, interest rate exposure, and the margin of safety against financial distress.
Key signals: the maturity schedule reveals concentration risk — large maturities within 1-2 years during tight credit markets can force dilutive refinancing or asset sales. Compare the fair value of debt against carrying amount to gauge whether the market views the company's credit risk differently than the balance sheet suggests. Watch covenant compliance disclosures for tightening cushions, especially leverage and interest coverage ratios. Variable-rate debt exposure quantifies sensitivity to interest rate changes. Secured versus unsecured mix affects recovery rates and future borrowing capacity. Compare net debt-to-EBITDA against industry peers and covenant limits to assess financial health.
